Theory to feveral natural Phenomena. § l. Of the Rainlo'w. f-pHIS beautiful phenomenon hath engaged the at- tention of all ages. By fome nations it hath been deified; though the more fenfible part always looked upon it as a natural appearance, and endeavoured, however imperfeftly, to account for it. The obfer- vations of the ancients and philofophers of the mid¬ dle ages concerning the rainbow were fuch as could not have efcaped the notice of the moft illiterate huf- bandmen who gazed at the iky; and their hypothe- fes were fuch as deferve no notice. Tt was a confi- derable time even after the dawn of true philofophy in this weftern part of the world, before we find any difcovery of importance on this fubjeft. Maurolycus was the firft who pretended to have meafured the dia¬ meters of the two rainbows with much exaftnefs; and he reports, that he found that of the inner bow to be 45 degrees, and that of the outer bow 56; from which Des Cartes takes occafion to obfcrve, how little we can depend upon the obfervations of thofe who were not acquainted with the caufes of appearances. One Clichtcyxus (the fame, it is probable, who di- ftinguiihed. himfelf by his oppofition to Luther, and who died in 1543) had maintained, that the fecond bow is the image of the firft, as he thought was evi- dent from the inverted order of the colours. For, faid he, when we look into the water, all the images that we fee refle&ed by it are inverted with refped to the obje&s themfelves; the tops of the trees, for in- Jtance, that itand near the brink, appearing lower than the roots. That the rainbow is oppofite to the fun, had al¬ ways been obferved. It was, therefore, natural to imagine, that the colours of it were produced by fome kind of reflexion of the rays of light from drops of rain, or vapour. The regular order of the colours was another circumftance that could not have efcaped the notice of any perfon. But, notwithftanding mere refiedlion had in no other cafe been obferved to pro¬ duce colours, and it could not but have been obferved 2 . Part III. that refra&ion is frequently attended with that phe- r nomenon, yet no perfon feems to have thought of ha- ving recourfe ts a proper refra&ion in this cafe, be- - ^ °" fore one Fletcher of Breflau, who, in a treatife which he publiihed in 1571, endeavoured to account for the colours of the rainbow by means of a double refrac¬ tion and one refleflion. But he imagined that a ray of light, after entering a drop of rain, and fuffering a refraftion both at its entrance and exit, was after¬ wards reflefled from another drop, before it reached the eye of the fpedlator. He feems to have ovei- looked the refleftion at the farther fide of the drop, or to have imagined that all the bendings of the light within the drop would not make a fufficient curvature to bring the ray of the fun to the eye of the fpe&ator. That he fiiould think of two refra&ions, was the ne- ceflary confequence of his fuppofing that the ray en¬ tered the drop at all. This fuppofition, therefore, was all the light that he threw upon the fubjecl. B.. Porta fuppofed that the rainbow is produced by the refraftion of light in the whole body of rain or vapour, but not in the feparate drops. After all, it was a man whom no writers allow to have had any pretenfions to philofophy, that hit upon this curious difcovery. This was Antonio De Do- minis, bifhop of Spalatro, whofe treatife De Radtis Vi- fus et Lucis, was publifhed by J. Bartolus in 1611. He firft advanced, that the double refraftion of Flet¬ cher, with an intervening reflexion, was fufficient to produce the colours of thi. bow, and alfo to bring the rays that formed them to the eye of the fpe&ator, without any fubfequent refle&ion. He diftindly dc- feribes the progrefs of a ray of light entering the up¬ per part of the drop, where it fuffers one refra&ion, and after being thereby thrown upon the back part of the inner furface, is from thence refleded to the lower part of the drop; at which place undergoing a fecond refraftion, it is thereby bent, fo as to come dire&ly to the eye. To verify this hypothefis, this perfon (no philofopher as he was) proceeded in a very fenfible and philofophical manner. For he procured a fmall globe of folid glafs, and viewing it when it was expo- fed to the rays of the fun, in the fame manner in which he had fuppoied that the drops of rain w*re fituated 31 K 2 with 5562 Of the Rainbow, OPT with refpeft to them, he aftually obferved the fame co¬ lours which he had feen in the true rainbow, and in the fame order. Thus the circumflances in which the colours of the rainbow were formed, and the progrefs of a ray of light through a drop of water, were clearly under- flood ; but philofophers were a long time at a lofs when they endeavoured to aflign reafons for all the particu¬ lar colours, and for the order of them. Indeed no¬ thing but the do&rine of the different refrangibility of the rays of light, which was a difcovery referved for the great Sir Ifaae Newton, could furnifn a complete folution of this difficulty. De Dominis fuppofed that the red rays were thofe which had traverfed the lead fpace in the infide of a drop of water, and therefore retained more of their native force, and confequently, linking the eye more brilkly, gave it a ftfonger fen- fation; that the green and blue colours were pro¬ duced by thofe rays, the force of which had been, in fome meafure, obtunded in pafiing through a greater body of water; and that all the intermediate colpurs were comppfed (according to the hypothefis which ge¬ nerally prevailed at that time) of a mixture of thefe three primary ones. That the different colours were caufed by fome difference in the impulfe of light upon the eye, and the greater or lefs impreflion that was thereby made upon it, was an opinion which had been adopted by many perfons, who had ventured to depart from the authority of Ariftotle. Afterwards the fame De Dominis obferved, that all the rays of the fame colour muft leave the drop of wa¬ ter in a part fimilarly fituated with refpeft to the eye, in order that each of the colours may appear in a circle, the centre of which is a point of the heavens, in a line drawn from the fun through the eye of the fpe&ator. The red rays, he obferved, muft iflue from the drop neareft to the bottom of it, in order that the circle of red may be the outermoft, and therefore the moft ele¬ vated in the bow. Notwithftanding De Dominis conceived fo juftly of the manner in which the inner rainbow is formed, he was far from having as juft an idea of the caufe of the exterior bow. This he endeavoured to explain in the very fame manner in which he had done the inte¬ rior, viz. by one refle&ion of the light within the drop, preceded and followed by a refraction ; fuppo- fing only that the rays which formed the exterior bow, were returned to the eye by a part of the drop lower than that which tranfmitted the red of the inte¬ rior bow. He alfo fuppofed that the rays which form¬ ed oneT)f the bows came from the fuperior part of the fun’s diik, and thofe which formed the other from the inferior part of it. He did not confider, that upon thofe principles, the two bows ought to have been contiguous; or rather, that an indefinite number of bows would have had their colours all intermixed; which would have been no bow at all. When Sir Ifaac Newton difeovered the different re¬ frangibility of the rays of light, he immediately ap¬ plied his new theory of light and colours to the phe¬ nomena of the rainbow, taking this remarkable objeft cf philofophical inquiry where De Dominis and Del- cartes, for want of this knowledge, were obliged to leave their inveftigations imperfeft. For they could give no good reafon why the bow fliould be coloured, ICS. Partlll. and much lefs could they give any fatisfa&ory account Of the of the order in which the colours appear. Rainbow If different particles of light had not different de- grees of refrangibility, on which the colours depend, the rainbow, befides being much narrower than it is, would be colourlefs; but the different refrangibility of differently coloured rays being admitted, the reafon is obvious, both why the bow fhould be coloured, and alio why the colours fliould appear in the order in which they are obferved. Let A, (fig. 2.) be a Hate drop of water, and S a pencil of light; which, on itsct‘XIV* leaving the drop of water, reaches the eye of the fpe&ator. This ray, at its entrqpce into the drop, begins to be decompofed into its proper colours; and upon leaving the drop, after one reflexion and a fe- cond refraflion, it is farther decompofed into as many fmall differently-coloured pencils, as there are primi¬ tive colours in the light. Three of them oply are drawn in this figure, of which the blue is the moft, and the red the leaft refrafted. The doctrine of the different refrangibility of light enables us to give a reafon for the fize of a bow of each particular colour. Newton, having found that the fines of refraftion of the moft refrangible and leaft refrangible rays, in paffing from rain-water into air, are in the proportion of 185 to 182, when the fine of incidence is 138, calculated the fize of the bow; and he found, that if the fun was only a phyfical point, without fenfible magnitude, the breadth of the inner bow would be 2 degrees ; and if to this 30’ was ad¬ ded, for the apparent diameter of the fun, the whole breadth would be 2^- degrees. But as the outermoft colours, efpecrally the violet, are extremely faint, the breadth of the bow will not, in reality, appear to ex¬ ceed two degrees. He finds, by the fame principles, that the breadth of the exterior bow, if it was every where equally vivid, would be 40 20'. But in this cafe there is a greater deduflion to be made, on account of the faintnefs of the light of the exterior bow; fo that, in faft, it will not appear to be more than 3 degrees broad. The principal phenomena of the rainbow are all explained on Sir Ifaac Newton’s principles in the fol¬ lowing propofnions. When the rays of the fun fall upon a drop of rain and enter into it, fome of them, after one reflection and two refractions, may come to the eye of a fpeClator who has his back towards the fun and his face toward the drop. If XY (fig. 6 ) is a drop of rain/* and the funpjate fhines upon it in any lines//j s d, s a. See. moft ofccxiir. the rays will enter into the drop; fome few of them only will-be reflected from the firft furface ; thofe rays, which are refle&ed from thence, do not Come under our prefent confideration, becaufe they are never re- frafted at all. The greateft part of the rays then en¬ ter the drop, and thofe paffing on to the fecond fur- face, will moft of them be tranfmitted through the drop; but neither do thofe rays which are thus tranf¬ mitted fall under our prefent confideration, fince they are not refle&ed. For the rays, which are deferibed in the propofition, are fuch as are twice refrafted and once reflected. However, at the fecond furface, or hinder part of the drop, at pg, fome few rays will be re.* Tlafe COXm. PartHI. OPT of the refie&ed, whilft the rays are tranfmitted : thofe rays R=,inho«'. proceed ;n fome fuch lines as nr, nq\ and coming out of the drop in the lines rv, qt, may fall upon the eye of a fpedtatof, who is placed any where in thofe lines, with his face towards the drop, and coniequent- ly with his back towards the fun, which is fuppofed to fhine upon the drop in the lines s f, s d, s a, &c. Thefe rays are twice refracted, and once reflected: they are refrafted when they pafs out of the air into the drop; they are refle&ed from the fecond furface, and are refra&ed again when they pafs out of the drop into the air. I When rays of light rejletted from a drop of rain come to the eye, thofe are called effeftuai ‘which are able to excite a fenfation. When rays of light come out of a drop of rain, they ‘will not be effettual, unlefs they are parallel and conti¬ guous. There are but few rays that can come to the eye at all: for the greateft part of thofe rays which enter the drop XY (fig. 6.) between X and a, pafs out of the drop thro’ the hinder furface pg ; only few are reflec¬ ted from thence, and come out through the nearer fur¬ face between a and^. Now, fuch rays as emerge, or come out of the drop, between a and Y, will be inef- feftual, unlefs they are parallel to one another, as r t; and qt are ; becaufe fuch rays as come out diverging from one another, will be fo far afunder when they come to the eye, that all of them cannot enter the pu¬ pil ; and the very few that can enter it will not be fufficient to excite any fenfation. But even rays, which are parallel, as rv, qt, will not be effe&ual, unlefs there are feveral of them contiguous or very near to one another. The two rays rv and qt alone will not be perceived, though both of them enter the eye ; for fo very few rays are not fufficient to excite a fenfation. When rays of light come out of a drop of rain after one refieftion, thofe ‘will be effectual •which are refieded from the fame point, and ‘which entered the drop near to one another. Any rays, as and c d, (fig. 7.) when they have pafled out of the air into a drop of water, will be re- frafted towards the perpendiculars hi, dl; and as the ray sb falls farther from the axis av than the ray cd, s b will be more refrafted than cd\ ia that thefe rays, though parallel to one another at their incidence, may defcribe the lines be and de after refra&ion, and be both of them reflefled from one and the fame point e. Now all rays which are thus refle&ed from one and the fame point, when they have defcribed the lines e/i eg, and after reflexion emerge at f and g, will be fo refracted, when they pafs out of the drop into the air, as todefcribe the lines/^, gi, parallel to one another. ' If thefe rays were to return from e in the lines eb, ed:, and were to emerge at b and d, they would be refrac¬ ted into the lines of their incidence b s, dc. But if thefe rays, inflead of being returned in the lines eb, e d, are refle&ed from the fame point e in the lines eg, ef the lines of refledfion ej1, and e/^will be inclined both to one another, and to the furface of the drop : juft as much as the lines eb and ed are. Firft eb and eg make juft the fame angle with the furface of the I c s. drop: forthe angle hex, which el makes with the furface of the drop, is the complement of incidence, and the angle gey, which eg makes with the furface,' is the complement of refle&ion ; and thefe two are equal to one another. In the fame manner we might prove, that ed and ef make equal angles with the furface of the drop. Secondly, The angle led is equal to the angle feg} or the refleded rays eg, ef, and the incident rays be, de, are equal¬ ly inclined to each other. For the angle of incidence b el \s equal to the angle of refledlion gel, and the angle of incidence de l \s equal to the angle of reflec¬ tion f e l; confequently the difference between the angles of incidence is equal to the difference between the angles of refle&ion, oxbel—del—gel—fel, or bed—gef. — Since therefore either the lines eg,ef, or the lines eb, e d, are equally inclined both to one an¬ other and to the furface of the drop ; the rays will be refradted in the fame manner, whether they were to return in the lines eb, ed, or are refledted in the lings* eg, ef. But if they were to return in the lines eb, the refradtion, when they emerge at b and d, would make them parallel. Therefore, if they are refledfed from one and the fame point e in the lines eg, ef, the refradtion, when they emerge at g and f, will likevvife make them parallel. But though fuch rays as are refledted from the fame point in the hinder part of a drop of rain, are parallel to one another when they emerge, and fo have one condition that is requifite towards making them effec¬ tual, yet there is another condition neceffary; for rays, that are effedtual, muft be contiguous, as well as paral¬ lel. And though rays, which enter the drop in diffe¬ rent places, may be parallel when they emerge, thofe only will be contiguous which enter it nearly at the fame place. Let XY, (fig. 6.) be a drop of rain, ag the axis or diameter of the drop, and / r? a ray of light that comes from the fun and enters the drop at the point a. This ray s a, becaufe it is perpendicular to both the furfa- ces, will pafs ftraight through the drop in the line agh without being refradted ; but any collateral rays that fall about s b, as they pafs through the drop, will be made to converge to their axis, and palling out at n will meet the axis at h-. rays which fall farther from the axis than s b, fuch as thofe which fall about sc, will likewife be made to converge; but then their fo¬ cus will be nearer to the drop than h. Suppofe there¬ fore i to be the focus to which the rays that fall about s c will converge, any ray s c, when it has deferihed the line co within the drop, and is tending to the fo¬ cus i, will pafs out of the drop at the point o. The ' rays that fall upon the drop about s d, more remote, ftill from the axis, will converge to a focus dill nearer than i, as fuppofe at k. Thefe rays therefore go out of the drop at p. The rays, that fall ftill more remote from the axis, as s e, will converge to a focus nearer than k, as fuppofe at l; and the ray s e, when it has defcribed the line eo within the drop, and is tending to /, will pafs out at the point 0. The rays, that fall ftill more remote from the axis, will converge to a focus ftill nearer. Thus the ray /f will after refradtion con¬ verge to a focus at m, which is nearer than l; and ha¬ ving defcribed the line fn within the drop, it will pafs out at the point n. Now here we may obferve, that 5563 Of the Rainbow. 5564 Of the Rainbow. OPT as any rays sb or / c, fall farther above the axis / a, the points or 0, where they pafs out behind the drop, will be farther above g; or that, as the inci¬ dent ray rifes from the axis 1 a, the zrcg no increafes, till we come to. fome ray / d, which paffes out of the drop at p : and this is the higheft point where any ray that falls upon the quadrant or quarter a x can pafs out: for any rays s e, or sf that fall higher than/*/, will not pafs out in any point above />, but at the points 0 or /r, which are below it. Confequently, tho* the arc gnop increafes, whilft the diftance of the in¬ cident ray from the axis s a increafed, till we come to the ray / d; yet afterwards, the higher the ray falls above the axis s a, this arc pong will decreafe. We have hitherto fpoken of the points on the hin¬ der part of the drop, where the rays pafs out of it? but this was for the fake of determining the points from whence thofe rays are refle&ed, which do not pafs out behind the drop. For, in explaining the rain¬ bow, we have no farther reafon to confider thofe rays which go through the drop j fince they can never come to the eye of a fpeflator placed any where in the lines rv or qt with his face towards the drop. Now, as there are many rays which pafs out of the drop be¬ tween g and p, fo fome few rays will be reflected from thence; and confequently the feveral points between £ and p, which are the points where fome of the rays pafs out of the drop, are likewife the points of reflec¬ tion for the reft which do not pafs out. Therefore, in refpeft of thofe rays which are reflefted, we may call gp the arc of refledlion; and many fay, that this arc of refle&ion increafes, as the diftance of the incident ray from the axis / a increafes, till we come to the ray sd\ the arc of refledtion is gn for the ray sb, it isj-0 for the ray sc, and gp for the ray s d. But after this, as the diftance of the incident ray from the axis sa increafes, the arc of refledlion decrea- fes; for 0g lefs than />£ is the arc of refledtion for the ray s e, and is the are of refledtion for the ■ vay sf. From hence it is obvious, that fome one ray, which falls above r d, may be refledted from the fame point with fome other ray which falls below s d. Thus, for inftance, the ray s b will be refledted from the point n, and the ray sf will be refledted from the fame point; and confequently, when the refledted rzyznr, n q, are refracted as they pafs out of the drop at r and q, they will be parallel, by what has been {hewn in the for¬ mer part of this propofition. But fine* the interme¬ diate rays, which enter the drop between sf and sb, are not refledted from the fame point n, thefe two rays alone will be the parallel to one another when they come ont of the drop, and the intermediate rays will not be parallel to them. And confequently thefe rays rv, qt, though they are parallel after they emerge at r and q^ will rot be contiguous, and for that reafon wilt not be effedtual ; the ray s d \$ refledted from />, which has been (hewn to be the limit of the arc of re- ffedtion ; fuch rays as fall juft above s d, and juft be¬ low s d, will be refledted from nearly the fame point />,~as appears from what has been already {hewn. Thefe rays therefore will be parallel, becaufe they are reflec¬ ted from the fame point />: and they will likewife be contiguous, becaufe they all of them enter the drop at one and the fame place very near to d. Confe- I C S. Partin quently, fuch rays as enter the drop at d, and are re- Of th< fledted from p the limit of the arc of refledtion, will Ra>nbo\ be effedtual; fince, when they emerge at the fore part ' of the drop between a and j’, they will be both parallel and contiguous. If we can make out hereafter that the rainbow is produced by the rays of the fun which are thus reflec¬ ted from drops of rain as they fall whilft the fun (hines upon them, this propofition may ferve to fhew us, that this appearance is not produced by any rays that fall upon any part, and are refledted from any part of thofe drops: fince this appearance cannot be produced by any rays but thofe which are effedtual; and effedtual rays muft always enter each drop at one certain place in the fore-part of it, and muft likewife be refledted from one certain place in the hinder furface. When rays that are effectual emerge from a drop of j rain after one reflection and two refractions, thofe which are mojl refrangible, will, at their emerfion, make a lefs angle with the incident rays than thofe do which are leaji refrangible ; and by this means the rays of different colours will be feparated from one another. Let fh and gi, (fig. 7.) be effedtual violet rays Plate emerging from the drop *tfg\ and f n, gp, effedtualCCXIH. red rays emerging from the fame drop at the fame place. Now, though all the violet rays are parallel to one another, becaufe they are fuppofed effedtual, and though all the red rays are likewife parallel to one another for the fame reafon ; yet the violet rays will not be parallel to the red rays. Thefe rays, as they have different colours, and different degrees of re- frangibility, will diverge from one another ; any vio¬ lent ray g i, which emerges at g, will diverge from any red ray gp, which emerges at the fame place. Now, both the violet ray gi, and the red ray gp, as they pafs out of the drop of water into the air, will be refradied from the perpendicular lo. But the violet ray is more refrangible than the red one; and for that rcafon g i, or the refradled violet ray, will make a greater angle with the perpendicular than gp the re- fradted red ray; or the angle igo will be greater than the angle pgo. Suppofe the incident ray / £ to be continued in the diredfion s k, and the violet ray ig to be continued backward in the dire&ion i k, till it meets the incident ray at k. Suppofe likewife the red ray pg to be continued backwards in the fame manner, till it meets the incident ray at w. The angle i k s is that which the violet ray, or moft refrangible ray at its emerfion, makes with the incident ray ; and the angle pws is that which the red ray, or leaft re¬ frangible ray at its emerfion, makes with the incident ray. The angle.//fa is lefs than the angle pws. For, in the triangle, g w k, g ws, or p w s, is the external angle at the bale, zn& g k 10 or iks is one of the in¬ ternal oppofite angles; and either internal oppofite angle is lefs than the external angle at the bafe. (Euc. b. I. prop. 16.) What has been (hewn to be true of the rays g i zn& gp might be (hewn in the fame man¬ ner of the rays fh and fn, or of any other rays that emerge refpedlively parallel to gi and gp. But all the effedtual violet rays are parallel to gi, and all the effedtual reel rays are parallel to gp. Therefore the effedtual violet rays at their emerfion make a leis angle PartHI. OPT ' Of the angle with the incident ones than the effe&ual red ones. f Rainbow. An(j for the fame reafon, in all the other forts of rays, thofe which are moft refrangible, at their emerfion from a drop of rain after one reflexion, will make a lefs angle with the incident rays, than thofe do which are lefs refrangible. Or otherwife : When the rays gi and gp emerge at the fame point gt as they both come out of water into air, and confequently are refra&ed from a perpendi¬ cular, inftead of going ftraight forwards in the line eg continued, they will both be turned round upon the point g from the perpendicular £ and will meet in a focus at e, fo that ge will be the principal focal diftance of this refle&ing furface fg. And becatife hi and/^ are parts of the fame fphere, the principal focal diftances^e and k i will be equal to one another. When the rays have pafled the focus e, they will diverge from thence in the lines ed, eb: and we are to (hew, that when they emerge at d and b, and are refra&ed there, they will become parallel. Now if the rays vk, wi, when they have met at k, were to be turned back again in the dire&ions tv, k]ate If rays of different colours, which are differently re- CCXIII. frangible, emerge at any point b, (fig. 8.) thefe rays will not be all of them equally refrafted from the per¬ pendicular. Thus, \ib o is a red ray, which is of all others the lead refrangible, and b m is a violet ray, which is of all others the moft refrangible; when thefe two rays emerge at b, the violet ray will be refradted more from the perpendicular b x than the red ray, and the refradled angle xbm will be greater than the refrac¬ ted angle xbo. From hence it follows, that thefe two rays, after emerfion, will diverge from one another. In like ma.fner, the rays that emerge at d will diverge frome one another; a red ray will emerge in the line dp, a violet ray in the line dt. So that though all the effedfual red rays of the beam bdmt are parallel to one another, and all the effedlual red rays of the beam bdop are likewife parallel to one another, yet the violet rays will not be parallel to the red ones, but the violet beam will diverge from the red beam. Thus the rays of dif¬ ferent colours will be feparated from one another. This will appear farther, if we confider what the pro- pofition affirms, That any violet or moft refrangible ray will make a greater angle with the incident rays, than any red or lead refrangible ray makes with the fame incident rays. Thus ifj w is an incident ray, b m a violet ray emerging from the point b, and boz red ray emerging from the fame point; the angle which Vol. VIII. a I C S. the violet ray makes with the incident one yrm, and that which the red ray makes with it isyso. NnWyrm is a greater angle than y so. For in the triangle brs the internal angle brs is lefs than bsy the externa! angle at the bafe. Euc. B. I. prop. 16. But yrm is the complement of irr or of bry to two right ones, andyso is the complement of bsy to two right ones. Therefore, fince bry is lefs than bsy, the complement of bry to two right angles will be greater than the complement of bsy to two right angles; or yrm will be greater than yso. Orotherwife: Both the rays bo and bm, when they are refra&ed in palling out of the drop at b, are turned round upon the point b from the perpendicular b x. Now either of thefe lines b o or bm might be turned round in thi» manner, till it made a right angle with yw. Confequently, that ray which is moft turned round upon b, or which is moft refrafted, will make an angle with yw that will be nearer to a right one than that ray makes with it which is leaft turned round upon b, or which is leaft refra&ed. Therefore that ray which is moft refrafted will make a greater angle with the in¬ cident ray than that which is leaft: refraded. But fince the emerging rays, as they are differently refrangible, make different angles with the fame inci¬ dent ray^w, the refradion which they fuffer at emer¬ fion will feparate them from one'another. The angle jrw, which the moft refrangible or vio¬ let rays make with the incident ones, is found by cal¬ culation to be 54° 7'; and the angle yso, which the leaft refrangible or red rays make with the incident ones, is found to be 50° 57': the angles, which the rays of the intermediate colours, indigo, blue, green, yellow, and orange, make with the incidents rays, are intermediate angles between 540 7' and 50° 57'. If a line is fuppofed to be drawn from the centre of the fun through the eye of the fpeftator; the angle, which, after two refraXions and two reflexions, any effeXual ray makes with the incident ray, will be equal to the the angle which it makes with that line. If yw (fig. 8.) is an incident ray, bo an effedual ray, and qti a line drawn from the centre of the fun through 0 the eye of the fpedator; the angle yso, which the effedual ray makes with the incident ray, is equal to son the angle which the fame effedual ray makes with the line qn. Forj/w and qn, confidered as drawn from the centre of the fun, are parallel; bo croffes them, and confequently makes the alternate angles yso, son, equal to one another. Euc. B. I. Prop. 29. When the fun fhines upon the drops of rain as they, are falling; the rays that come from thefe drops to the eye of a fpeXator, after two refleXions and two refrac¬ tions, produce the fecondary rainbow. The fecondary rainbow is the outermoft CHD, fig. 9. When the fun (bines upon a drop of rain H; and the rays HO, which emerge at H fo as to be ef¬ fedual, make an angle HOP of 540 7 with LOP a line drawn from the fun through the eye of the fpec- tator; the fame effedual rays will make likewife an angle of 54° 7' with the incident rays S, and the rays which emerge at this angle are violet ones, by what was obferv-d above. Therefore, if the fpedator’s ey e 5567 Rainbow. 5568 Of the Rainbow. OPT is at O, none but violet rays will enter it: for as all the other rays make a lefs angle with OP, they will fall above the fpe&ator’s eye. In like manner, if the ef¬ fectual rays that emerge frorn the drop G make an angle of 50° 57' with the line OP, they will likewife make the fame angle with the incident rays S; and confequently, from the drop. G to the fpeCtator’s eye at O, no rays will come but red ones; for all the other rays, making a greater angle with the line OP, will fall below the eye at O. For the fame reafon, the rays emerging from the intermediate drops between H and G, and coming to the fpeftator’s eye at O, will emerge at intermediate angles, and therefore will have the in¬ termediate colours. Thus, if there are feyen drops from H to G inchifively* their colours will be violet, indigo, blue, green, yellow, orange, and red. This coloured line is the breadth of the fequndary rainbow. Now, if HOP was to turn round upon the line OP, like a pair of compafles upon one of the legs OP with the opening HOP, it is plain from the fuppofition, that, in fuch a revolution of the drop H, the angle HOP would be the fame, and confequently the emer¬ ging rays would make the fame angle with the inci¬ dent ones. But in fuch a revolution the drop would defcribe a circle of which P would be the centre, and CNHRD an arc. Confequently, fince, when the drop is at N, or at R, or any where elfe in that arc, the emerging rays make the fame angle with the incident ones as when the drop is at H, the colour of the drop will be the fame to an eye placed at O, whether the drop is at N, or at H, or at R, or any where elfe in that arc. Now, though the drop does not thus turn round as it falls, and does not pafs through the feveral parts of this arc, yet, fince there are drops of ruin fall¬ ing every where at the fame time, when one drop is at H, there will be another at R, another at N, and others in all parts of the arc; and thefe drops will all of them be violet-coloured, for the fame reafon that the drop H would have been of this colour if it had been in any of thofe places. In like manner, as the drop G is red when it is at G, it would likewife be red in any part of the arc CWGQD; and fo will any other drop, when, as it is falling, it comes to any part of that arc. Thus as the fun (bines upon the rain, whilft it falls, there will be two arcs produced, a violet coloured one CNHRD, and a red one CWGQD; and for the fame reafons the intermediate fpace between thefe two arcs will be filled up with arcs of the intermediate colours. All thefe arcs together make up the fecondary rain¬ bow. The colours of the fecondary ralnbonu are fainter than thofe of the primary rainboiu ; and are ranged in the contrary order. The primary rainbow is produced by fuch rays as have been only once reflefted; the fecondary rainbow is produced by fuch rays as have been twice refle&ed. But at every reflexion fome rays pafs out of the drop of rain without being refle&ed; fo that the oftener the rays are tefle&ed, the fewer of them are left. There¬ fore the colours of the fecondary bow are produced by fewer rays, and confequently will be fainter, than the colours of the primary bow. In the primary .bow, reckoning from the outfide of it, the colours are ranged in this order; red, orange, ICS. Part ill. yellow, green, blue, indigo, violet. In the feeondary Apparent bow, reckoning from the outfide, the colours are vio- Plare, &e. let, indigo, blue, green, yellow, orange, red. So that of ot>jefts. the red, which is the outermoft or higheft colour in the primary bow, is the innermoft or lowed colour in the fecondary one. Now the violet rays, when they emerge fo as to be effe&ual after one refleftion, make a lefs angle with the incident rays than the red ones; confeqnently the violet rays make a lefs angle with the lines OP (fig. 9.) Plate than the red ones. But, in the primary rainbow, the CCXIii, rays are only once refledted, and the angle which the effe&ual rays make with OP is the diftance of the co¬ loured drop from P the centre of the bow. Therefore the violet drops,or violet arc, in the primary bow, will be nearer to the centre of the bow, than the red drops or red arc; that is, the innerajoft colour in the primary bow wifi be violet, and the outermoit colour will be red. And, for the fame reafon, through the whole pri¬ mary bow, every colour will be nearer to the centre P, as the rays of that colour are more refrangible, But the violet rays, when they emerge fo as to be effectual after two refle&ions^ make a greater angle with the incident rays than the red ones; confequently the violet rays will make a greater angle with the line OP, than the red ones. But in the fecondary rain¬ bow the rays are twice reflefted, and the angle which effeftual rays make with OP is the diftance of the co¬ loured drop from P the centre of the bow. Therefore the violet drops or violet arc in the fecondary bow will be farther from the centre of the bow than the red drops or red arc; that is, the outermoft colour in the fecondary bow will be violet, and the innermoft co¬ lour will be red. And, for the fame reafon, through the whole fecondary bow, every colour will be further from the centre P, as the rays of that colour are more refrangible. § 2. Of Coronas, Parhelia, &c. Under the articles Corona and Parhelion a pretty full account is given of the different hypothefes concerning thefe phenomena, and likewife of the me¬ thod by which thefe hypothefes are fupported, from the known laws of refraaion and reflexion ; to which therefore, in order to avoid repetition, we muft refer. $ 3* Of the Apparent Place, Di/lance, Magnitude, and Motion of Objetts. Philosophers in general had taken for granted, that the place to which the eye refers any vifible ob-, jedk feen by refleftion or refraiftion, is that in which the vifual ray meets a perpendicular from the objeft upon the refle&ing or refrading plane. But this me¬ thod of judging of the place of objtds was called in queftion by Dr Barrow, who contended that the ar¬ guments brought in favour of the opinion were not conclufive. Thefe arguments are, that the images of objeds appear ftraight in a plane mirror, but curved in a convex or concave one: that a ftraight thread, when partly immerfed perpendicularly in water, does not appear crooked as when it is obliquely plunged into the fluid ; but that which is within the water feems to be a continuation of that which is without. With re- fped to the refleded image, however, of a perpen¬ dicular right line from a convex, or concave mirror, he PartHI. OPT Apparent he fays, that it is not eafy for the eye to diftinguifti P|ac®! ^c* the curve that it really makes; and that, if the ap- ° 0 J£ s* pearance of a perpendicular thread, part of which is plunged in water, be clofely attended to, it will not favour the common hypothefis. If the thread is of any fhining metal, as filver, and viewed obliquely, the image of the part immerfed will appear to detach itfelf feniibly from that part which is without the water, fo that it cannot be true that every objeft ap¬ pears to be in the fame place where the refracted ray meets the perpendicular; and the fame obfervation he thinks may be extended to the cafe of refledtion. Ac¬ cording to this writer, we refer every point of an ob- je6t to the place from which the pencils of light, that give us the image of it, iflue, or from which they would have ifiued if no refledling or refradting fub- ftance intervened. Purfuing this principle, he pro¬ ceeds to inveftigate the place, in which the rays iffuing from each of the points of an objedt, and which reach the eye after one refle&ion or refradfion, meet; and he found, that, if the refradling furface was plane, and the refradtion was made from a denfer medium into a rarer, thofe rays would always meet in a place between the eye and a perpendicular to the point of incidence. If a convex mirror be ufed, the cafe will be the fame ; but if the mirror be plane, the rays will meet in the perpendicular, and beyond it if it be con¬ cave. He alfo determined, according to thefe prin¬ ciples, what form the image of a right line will take, when it is prefented in different manners to a fpheri- cal mirror, or when it is feen through a refradling medium. Probable as Dr Barrow thought the maxim which he endeavoured to eftabliih, concerning the fuppofed place of vifible objedts, he has the candour to mention an objedlion to it, and to acknowledge that he was not able to give a fatisfadtory folution of it. It is this. Let an objedt be placed beyond the focus of a convex lens; and if the eye be clofe to the lens, it will appear confufed, but very near to its true place. If the eye be a little withdrawn, the confufion will increafe, and the objedl will feetn to come nearer; and when the eye is very near the focus, the confufion will be ex¬ ceedingly great, and the objedt will feem to be clofe to the eye. But in this experiment the eye receives no rays but thofe that are converging; and the point from which they iffue is fo far from being nearer than the objedt, that it is beyond it; notwithftanding which, the objedt is conceived to be much nearer than it is, though no very diftindt idea can be formed of its precife diftance. It may be obferved, that, in reality, the rays falling upon the eye in this cafe in a manner quite different from that in which they fall upon it in other circumftances, we can form no judge¬ ment about the place from which they iffue. This fubjedt was afterwards taken up by Berkley, Smith, Montucla, and others. M. De la Hire made feveral valuable obfervations concerning the diftance of vifible objedls, and various Other phenomena of vifion, which are well worth our notice. He alfo took particular pains to afeertain the manner in which the eye conforms itfelf to the view of objedts placed at different diftances. He enumerates five circumftances, which afiift us in judging of the diftance of objedts, namely, their apparent magnitude, ICS. | 5565 the ftrength of the colouring, the direAion of the two Apparent eyes, the parallax of the objedts, and the diftindtnefs of their fmall parts. Painters, he fays, can only take 0 ^ ‘ advantage of the two firft mentioned circumftances, and therefore pidtures can never perfedtly deceive the eye ; but in the decorations of theatres, they, in fome meafure, make ufe of them all. The fize of objedts, and the ftrength of their colouring, are diminiftied in proportion to the diftance at which they are intended to appear. Parts of the fame objedt which are to ap¬ pear at different diftances, as columns in an order of architcdture, are drawn upon different planes, a little removed from one another, that the two eyes may be obliged to change their diredtion, in order to diftin¬ guifti the parts of the nearer plane from thofe of the more remote. The fmall diftance of the planes ferves to make a fmall parallax, by changing the pofition of the eye ; and as we do not preferve a diftindt idea of the quantity of parallax, correfponding to the different diftances of objedts, it is fufficient that we perceive there is a parallax, to be convinced tha^ thefe planes are diftant from one another, without determining what that diftance is; and as to the laft circumftance, viz. the diftindtnefs of the fmall parts of objedts, it is of no ufe in difeovering the deception, on account of the falfe light that is thrown upon thefe decorations. To thefe obfervations concerning deceptions of Fight, we fhall add a fimilar one of M. Le Cat, who took notice that the reafon why we imagine objedts to be larger when they are feen through a mift, is the dimnefs or obfeurity with which they are then feen ; this circumftancc being affociated with the idea of great diftance. This he fays is confirmed by our be¬ ing furprifed to find, upon approaching fuch objedts, that they are fo much nearer to us, as well as fo much fmaller, than we had imagined. Among other cafes concerning vifion, which fell under the confideration of M. De la Hire, he men¬ tions one which is of difficult folution. It is when a candle, in a dark place, and fituated beyond the limits of diftindt vifion, is viewed through a very nar¬ row chink in a card ; in which cafe a confiderable number of candles, fometimes fo many as fix, will be feen along the chink. This appearance he aferibes to ftnall irregularities in the furface of the humours of the eye, the effedt of which is not fenfible when rays are admitted into the eye through the whole extent of the pupil, and confequently one principal image effaces a number of fmall ones; whereas, in this cafe, each of them is formed feparately, and no one of them is fo confiderable as to prevent the others from being per¬ ceived at the fame time. There are few perfons, M. De la Hire obferves, who have both their eyes perfedtly equal, not only with refpedt to the limits of diftindt vifion, but alfo with refpedt to the colour with which objedts appear tinged when they are viewed by them, efpecially if one of the eyes has been expofed to the impreffion of a ftrong light. To compare them together in this re¬ fpedt, he diredts us to take two thin cards, and to make in each of them a round hole of a third or a fourth of a line in diameter, and, applying one of them to each of the eyes, to look through the holes on a white paper, equally illuminated ; when a circle of the paper will appear to each of the eyes, and, placing 31 L z the 557° OPT Apparent the cards properly, thefe two circles may be made to Pfob'efts' touc^ one anotl)er> an<^ thereby the appearance of the 0 J Sl fame objeft to each of the eyes may be compared to the greateft advantage. To make this experiment with the greateft exa&nefs, it is neceflary, he fays, that the eyes be kept (hut fome time before the cards be applied to them. M. De la Hire firft endeavoured to explain the caufe of thofe dark fpots which feem to float before the eyes, cfpecially thofe of old people. They are moft vifible when the eyes are turned towards an uniform white objeft, as the fnow in the open fields. If they be fixed when the eye is fo, this philofopher fuppofed that they were occafioned by extravafated blood upon the retina. But he thought that the movable fpots were occafioned by opaque matter floating in the aqueous humour of the eye. He thought the vitreous humour was not fufficiently limpid for this purpofe. By the following calculation M. De la Hire gives us an idea of the extreme fenfibility of the optic nerves. One may fee very eafily, at the diftance of 4000 tojfes, the fail of a wind-mill, 6 feet in diameter; and the eye being fuppofed tobe an inch in diameter, thepidure of this fail, at the bottom of the eye, will be of an inch, which is lefs than the 666th part of a line, and is about the 66th part of a common hair, or the 8th part of a fingle thread of filk. So fmall, therefore, muft one of the fibres of the optic nerve be, which he fays is almoft inconceivable, fince each of thefe fibres is a tube that contains fpirits. If birds perceive di- ftant objefts as well as men, which he thought very probable, he obferves that the fibres of their optic nerves muft be much finer than ours. The perfon who firft took much notice of Dr Bar¬ row’s hypothefis was the ingenious Dr Berkley, biftiop of Cloyne, who diftinguiflied himfelf fo much by the objedions which he darted to the reality of a material world, and by his oppofition to the Newtonian doc¬ trine of fluxions. In his effay on a new theory of viison, he obferves, that the circle formed upon the retina, by the rays which do not come to a focus, produce the fame confufion in the eye, whether they crofs one another before they reach the retina, or tend to do it afterwards; and therefore that the judgment concerning diftance will be the fame in both the cafes, without any regard to the place from which the rays originally ifiued ; fo that in this cafe, as, by receding from the lens, the confufion, which always , accompanies the nearnefs of an objed, increafes, the mind will judge that the objed comes nearer. But, fay Dr Smith, if this be true, the objed ought always to appear at a lefs diftance from the eye than that at which objeds are feen diftindly, which is not the cafe : and to explain this appearance, as well as every other in which a judgment is formed concerning diftance, he maintains, that we judge of it by the apparent magnitude of objeds only, or chiefly; fo that, fince the image grows lager as we recede from the lens through which it is viewed, we conceive the objed to come nearer. He alfo endeavours to (hew, that, in all cafes in which glades are ufed, we judge of diftance by the fame Ample rule; from which he concludes univerfaily, that the apparent diftance of an objtd feen in a glafs, is to its apparent diftance ieen by the naked eye, as ;he apparent magnitude to I C S. Part III. the raked eye is to its apparent magnitude in the glafs. Apparent But that we do not judge of diftance merely by the angle under which objeds are feen, is an nhfervation 0 °>je s‘ as old as Alhazen, who mentions feveral inftances, in which, though the angles under which objeds appear be different, the magnitudes are univerfaily and in- ftantaneoufly deemed not to be fo. And Mr Robins clearly (hews the hypothefis of Dr Smith to be con¬ trary to fad in the moft common and fimple cafes. In microfcopes, he fays, it is impoffible that the eye (hould judge the objed to be nearer than the dittance at which it has viewed the objed itfelf, in proportion to the degree of magnifying. For when the micro- fcope magnifies much, this rule would place the image at a diftance, of which the fight cannot poffibly form any opinion, as being an interval from the eye at which no objed can be feen. In general, he fays, he believes, that whoever looks at an objed through a convex glafs, and then at the objed itfelf, without the glafs, will find it to appear nearer in the latter cafe, though it be magnified in the glafs; and in the fame trial with the concave glafs, though by the glafs the objed be diminiflied, it will appear nearer through the glafs than without it. But the moft convincing proof that the apparent diftance of the image is not determined by its apparent magnitude is the following experiment. If a double convex glafs be held upright before fome luminous objed, as a candle, there will be feen two images, one ered, and the other inverted. The firft is made Amply by refledion from the neareft furface, the fecond by refledion from the farther furface, the rays undergoing a refradion from the firft furface both be¬ fore and after the refledion. If this glafs has not too (hort a focal diftance, when it is held near the objed, the inverted image will appear larger than the other, and alfo nearer; but if the glafs be carried off from the objed, though the eye remain as near to it as be¬ fore, the inverted image will diminifti fo much fafter than the other, that, at length, it will appear very much lefs than it, but ftill nearer. Here, fays Mr Robins, two images of the fame objed are feen under one view, and their apparent diftances immediately compared ; and here it is evident, that thofe diftances have no neceffary connedion with the apparent mag¬ nitude. He alfo (hews how this experiment may be made ftill more convincing, by (licking a piece of paper on the middle of the lens, and viewing it thro' a (hort tube. M. Bouguer adopts the general maxim of Dr Bar- row, in fuppofing that we refer objeds to the place from which the pencils of rays feemingly converge at their entrance into the pupil. But when rays iffue from below the furface of a veffel of water, or any other refrading medium, he finds that there are always two different places of this feeming convergence ; one of them of the rays that iffue from it in the fame ver¬ tical circle, and therefore fall with different degrees of obliquity upon the furface of the refrading medium ; and another, of thofe that fall upon the furface with the fame degreeof obliquity, entering the eye laterally with refped to one another. Sometimes, he fays, one of thefe images is attended to by the mind, and fometimes the other, and different images may be ob- ferved by different perfgns. An objed plunged in water Partlll. OPT Apparent water affords an example^ he fays, of this duplicity of piac!’ ^c' images. 0 0 Je s‘ If BA b, fig. 1. be part of the furface of water, Plate and the objeA be at O, there will be two images of CCXIII. it, in two different places ; one at G, on the cauftic by refra&ion, and the other at E, in the perpendicu¬ lar AO, which is as much a cauftic as the other line. The former image is vifible by the rays ODM, O dm, which are one higher than the other, in their progrefs to the eye ; whereas the image at E is made by the rays 0DM,0 ef, which enter the eye laterally. This, fays he, may ferve fo explain the difficulty of Father Tacquct, Barrow, Smith, and many other authors, and which Newton himfelf confidered as a very diffi¬ cult problem, though it might not be abiolutely info- luble. G. W. Krafft has ably fupported the opinion of Dr Barrow, that the place of any point, feen by reflec¬ tion from the furface of any medium, is that in which rays iffuing from it, infinitely near to one another, would meet; and confidering the cafe of a diftant ob- jedi, viewed in a concave mirror, by an eye very near to it, when the image, according to Euclid and other writers, would be between the eye and the objedt, and the rule of Dr Barrow cannot be applied, he fays that in this cafe the fpeculum may be confidered as a plane, the effedl being the fame, only the image is more obfcure. Dr Porterfield gives a diftindl and comprehenfive view of the natural methods of judging concerning the diftance of objedls. The conformation of the eye, he obferves, can be of no ufe to us with refpedf to objefts that are placed without the limits of diftinft vifion. As the objedt, however, does then appear more or lefs confufed, ac¬ cording as it is more or lefs removed from thofe li¬ mits, this confufion affifts the mind in judging of the diftance of the objedf; it being always efteemed fo much the nearer, or the farther off, by how much the confufion is greater. But this confufion hath its li¬ mits alfo, beyond which it can never extend; for when an objedtis placed at a certain diftance from the eye, to which the breadth of the pupil bears no fen- fible proportion, the rays of light that come from a point in theobjedf, and pafs the pupil, are fo little di- verging, that they may be confidered as parallel. For a pidture on the retina will not be fenfibly more con- ^ £ufed, tho’ the objsdfc be removed to a much greater diftance. The moft univerfal, and frequently the mod fure means of judging of the diftance of objedls is, he fays, the angle made by the optic axis. For our two eyes are like two different ftations, by the affiftance of which diftanees are taken ; and this is the feafon why thofe perfons who are blind of one eye, fo frequently mifs their mark in pouring liquor into a glafs, bluf¬ fing a candle, and fuch other adlions as require that the diftanct be exadly diftinguiftied. To convince ourfelves of the ufefulnefs of this method ofjudging of the diftance of objedls, he diredls us to fufpend a ring in a thread, fo that its fide may be towards us, and the hole in it to the right and left hand ; and taking a fmall rod, crooked at the end, retire from the ring two or three paces, and having with one hand cover¬ ed one of our eyes} to endeavour with the other to ICS. ... pafs the crooked end of the rod thro’ the ring. This, Apparent fays he, appears very eafy ; and yet, upon trial, per- haps once in 100 times we fhall not fucceed, efpe- J cially if we move the rod a little quickly. Our author obferves, that by perfons recolle&ing the time when they began to be fubjeft to the mi- flakes above-mentioned, they may tell when it was that they loft the ufe of -one of their eyes; which, many perfons are long ignorant of, and which may be a circumftance of fome confequence to a phyfician f. f See The ufe of this fecond method of judging of diftances Mediant, De Chales limited to 120 feet; beyond which, he fays,n 4Ji we are not fenfible of any difference in the angle of the optic axis, A third method ofjudging of the diftance of ob- je£ls, confifts in their apparent magnitudes, on which fo much ftrefs was laid by Dr Smith. From this change in the magnitude of the image upon the reti¬ na, we eafily judge of the diftance of objedls, as often as we are otherwife acquainted with the magnitude of the objedls themfeives ; but as often as we are igno¬ rant of the real magnitude of bodies, we can never, from their apparent magnitude, form any judgment of their diftance. From this we may fee why we are fo frequently de¬ ceived in our eftimates of diftance, by any extraordi¬ nary magnitudes of objedls feen at the end of it; as, in travelling towards a large city, or a caftie, or a ca¬ thedral church, or a mountain larger than ordinary, we fancy them to be nearer than we find them to be. This alfo is the reafon why animals, and all fmall ob¬ jedls, feen in valleys, contiguous to large mountains, appear exceedingly fmall. For we think the moun¬ tain nearer to us than if it were fmaller ; and we fiiould not be furprifed at the fmallnefs of the neigh¬ bouring animals, if we thought them farther off. For the fame reafon, we think them exceedingly fmall when they are placed upon the top of a moun¬ tain, or a large building ; which appear nearer to us than they really are, on account of their extraor¬ dinary fize. Dr Jurin clearly accounts for our imagining objedls, when fien from a high building, to be fmaller than they are, and fmaller than we fancy them to be when we view them at the fame diftance on level ground. It is, fays he, becSufe we have no diftindl idea of di¬ ftance in that direction, and therefore judge of things by their pidlures upon the eye only; but cuftom will enable us to judge rightly even in this cafe. Let a boy, fays he, who has never been upon any high building, go to the top of the monument, and look down into the fires.t; the objedls feen there, as men and horfes, will appear fo fmall as greatly to fur- prife him. But 10 or 20 years after, if in the mean time he has ufed himfelf now and then to look down from that and other great heights, he will no longer find the fame objedls to appear fo fmall. And if he was to view the fame objedts from fuch heights as frequently as he fees them upon the fame level with, himfelf in the ftreets, he fuppofes that they would ap¬ pear to him juft of the fame magnitude from the top of the monument, as they do from a window one ftory high. For tliis reafon it is, that flatues placed upon very high buildings ought to be made of a larger fize than thofe which are feen at a nearer di¬ ftance 3, 5572 Apparent place, &c, of objefls. OPT fiance ; becaufe all perfons, except architedls, are apt to imagine the height of fuch buildings to be, much lefs than it really is. The fourth method by which Dr Porterfield fays that we judge of the diftance of obje&s, is, the force with which their colour ftrikes upon our eyes. For if we be affured that two objefts are of a fimilar and like colour, and that one appears more bright and lively than the other, we judge that the brighter objedt is the nearer of the two. The fifth method confiils in the different appearance of the fmall parts of objefts. When thefe parts appear diftindt, we judge that the objedi is near; but when they appear confufed, or when they do not appear at all, we judge that it is at a greater diftance. For the image of any objedt, or part of an objedt, diminifhes as the diftance of it increafes. The fixth and laft method by which we judge of the diftance of obje&s'is, that the eye does not repre- fent to our mind one objedt alone, but at the fame time all thofe that are placed betwixt us and the prin¬ cipal objedt, whofe diftance we are confidering; and the more this diftance is divided into feparate and di- ftindt parts, the greater it appears to be. For this reafon, diltances upon Uneven furfaces appear lefs than upon a plane; for the inequalities of the furfaces, fuch as hills, and holes, and rivers, that lie low and out of fight, either do not appear, or hinder the parts that lie behind them from appearing; and fo the whole apparent diftance is diminifhed by the parts that do not appear in it. This is the reafon that the banks of a river appear contiguous to a diftant eye, when the river is low and not feen. Dr Porterfield very well explains feveral fallacies in -vifion depending upon our miftaking the diftances of objedfs. Of this kind, be fays, is the appearance of parallel lines, and long viftas confiding of parallel rows of trees; for they feem to converge more and more, as they are farther extended from the eye. The reafon of this, he fays, is becaufe the apparent mag¬ nitudes of their perpendicular intervals are perpetual¬ ly diminifhing, while, at the fame time, we miftake their diftance, Hence we may fee why, when the two parallel rows of trees ftand upon an afcent, whereby the more remote parts appear farther off than they really are, becaufe the line that meafures the length of the viftas now appears under a greater angle than when it was horizontal, the trees, in fuch a cafe, will feem to converge lefs, and fometimes, inftead of conver¬ ging, they will be thought to diverge. >> For the fame reafon that a long villa appears to converge more and rtiore the farther it is extended from the eye, the remoter parts of a horizontal walk or a long floor will appear to afcend gradually; and objedls placed upon it, the more remote they are, the higher they will appear, till the laft be fee a on a level with the eye ; whereas the Ceiling of a long gallery appears to defcend towards a horizontal line, drawn from the eye of the fpedlator. For this reafon, alfo, the furface of the fea, feen from an eminence, feems to rife higher and higher the farther we look; and the upper parts of high buildings feem to (loop, or in¬ cline forvvards over the eye below, becaufe they feem to approach towards a vertical line proceeding from the fpe&ator’a eye; fo that llatues on the top of fuch ICS. Part III, buildings, in order to appear upright, muft recline, Apparent or bend backwards. Our author alfo (hews the reafon why a windmill,. 0 ° } feen from a great diftance, is fometimes imagined to move the contrary way from what it really does, by our taking the nearer end of the fail for the more re¬ mote. The uncertainty we fometimes find in the courfe of the motion of a branch of lighted candles, turned round at a diftance, is owing, he fays, to the fame caufe ; as alfo our fometimes miftaking a convex fora concave furface, more efpecially in viewingfeals, and impreffions, with a convex glafs or a double mi- crofcope; and laftly, that, upon coming in a dark night into a ftreet, in which there is but one row of lamps, we often miftake the fide of the ftreet they are on. Far more light was thrown upon this curious fub- jeft by M. Bouguer. The proper method of drawing the appearance of two rows of trees that (hall appear parallel to the eye, is a problem which has exercifed the ingenuity of fe¬ veral philofophers and mathematicians. That the ap¬ parent magnitude of obje&s decreafes with the angle under which they are feen, has always been acknow¬ ledged. it is alfo acknowledged, that it is only by cuftom and experience that we learn to form a judg¬ ment both of magnitudes and diftances. But in the application of thefe maxims to the above-mentioned problem, all perfons, before M. Bouguer, made ufc of the real diftance inftead of the apparent one; by which only the mind can form its judgment. And it is manifeft, that, if any circumdances contribute to make the diftance appear otherwife than it is in rea¬ lity, the apparent magnitude of the object will be affe&ed by it ; for the fame reafon, that, if the mag¬ nitude be mifapprehended, the idea of the diftance will vary. For want of attending to this diftinftion, Tacquet pretended to demonftrate, that nothing can give the idea of two parallel lines (rows of trees for inftance) to an eye fituated at one of their extremities, but two hyperbolical curves, turned the contrary way ; and M. Varignon maintained, that in order to make a vifta appear of the fame width, it muft be made nar¬ rower, inftead of wider, as it recedes from the eye. M. Bouguer obferves, that very great diftances, and thofe that are confiderably lefs than them, make near¬ ly the fame impreffion upon the eye. We, therefore, always imagine great diftances to be lefs than they are, and for this reafon the ground-plan of a long villa al¬ ways appears to rife. The vifual rays come in a de¬ terminate direction; but as we imagine that they ter¬ minate fooner than they do, we neceffarily conceive that the place from which they iffue is elevated. E- very large plane, therefore, as AB, fig. 4. viewed Plate by an eye at O, will feem to lie in fuch a dire&ion as CCXIU, A b; and confequently lines, in order to appear truly parallel on the plane AB, mull be drawn fo as that they would appear parallel on the plane Ab, and be from thence proje&ed to the plane AB. Todetermine the inclinationof the apparent ground- plane A 3 to the true ground-plane AB, our ingeni¬ ous author dire&s us to draw upon a piece of level ground, two ftraight lines of a fuffieient length, (for which purpofe lines fattened to iinall flicks are very con- fart III. OPT Apparent convenient), making an angle of 3 or 4 degrees with place, &<*, one another. Then a perfon, placing himfelf within of objects. t^g with his back towards the angular point, muft walk backwards and forwards till be can fancy the lines to be parallel. In this fituation, a line drawn from the point of the angle thro’ the place of his eye, will contain the fame angle with the true grpund- plane which this does with the apparent one. M. Bouguer then (hews other more geometrical methods of determining this inclination ; and fays, that by thefe means he has often found it to be 4 or 5 degrees, though fometimes only 2 or degrees. The determination of this angle, he obferves, is variable ; depending upon the manner in which the ground is il¬ luminated, and the intenfity of the light. The colour of the foil is alfo not without its influence, as well as the particular conformation of the eye, by which it is more or lefs affeded by the fame degree of light, and alfo the part of the eye on which the objeft is paint¬ ed. When, by a flight motion of his head, he con¬ trived, that certain parts of the foil, the image of which fell towards the bottom of his eye, fhould fall towards the top of the retina, he always thought that this apparent inclination became a little greater. But what is very remarkable, and what he fays he can aflure his reader may be depended upon, is, that, if he look towards a rifing ground, the difference be¬ tween the apparent ground-plan and the trite one, will be much more confiderable, fo that they will fome¬ times make an angle of 25 or 30 degrees. Of this he had made frequent obfervations. Mountains, he fays, begin to be inaccelBble when their fides made an angle from 35 to 37 degrees with the horizon, as then it is not poflible to climb them but by means of ftones or fhrubs, to ferve as fteps to fix the feet on. In thefe cafes, both he and his companions always agreed that the apparent inclination of the fide of the mountain was 60 or 70 degrees. Plate Thefe deceptions are reprefented in fig. 3. in which, CCXIII. when the ground plan, AM, or AN, are much incli¬ ned, the apparent ground plan Km, or Atz, makes a very large angle with it. On the contrary, if the ground dips below the level, the inclination of the ap¬ parent to the true ground-plan diminilhes, till, at a certain degree of the flope, it becomes nothing at all; the two plans AP and Kp being the fame, fo that pa¬ rallel lines drawn upon them would always appear fo.. If the inclination below the horizon is carried beyond the fituation AP, the error will increafe; and what is very remarkable, it will be on the contrary fide; the apparent plan A r being always below the true plan AR, fo that if a perfon would draw upon the plan AR lines that fhall appear parallel to the eye, they muft be drawn converging, and not diverging, as is ufual on the level ground, becaufe they muft be the projections of two lines imagined to be parallel, on the plan A r, which is more inclined to the horizon than AR. Thefe remarks, he obferves, are applicable to differ¬ ent planes expofed to the eye at the fame time. For if BH, fig. 2. be the front of a building, at the di- ftance of AB from the eye, it will be reduced in ap¬ pearance to the diftance Kb; and the front of the building will be bb> rather inclined towards the fpec- Jator, unlefs the diftance be inconfiderable. After making a great number of obfervationa upon 1 c s. 5573 this fubjed, our author concludes, that when a man Apparent Hands upon a level plane, it does not feem to rife fen- p|.acf’-fl*"’ fibly but at fome diftance from him. The apparent 0 0 je. s\ plane, therefore, has a curvature in it, at that diftance, the form of which is not very eafy to determine; fo that a man ftanding upon a level plane, of infinite ex¬ tent, will imagine that he Hands in the centre of a ba- fon. This is alfo, in fome meafure, the cafe with a perfpn Handing upon the level of the fea. He concludes with obferving that there is no di- ficulty in drawing lines according to thefe rules, fo as to have any given tffeCl upon the eye, except when fome parts of the profped are very near the fpedator, and others very diftant from him; becaufe, in this cafe, regard muH be had to the conical or conoid®! figure of a furface. A right line palling at a fmall diHance from the obferver, and below the level of his eye, in that cafe almott always appears fenfibly curved at a certain diHance from the eye; and almolt all figures, in this cafe, are fubjed to fome complicated optical alteration to which the rules of perfpedive have not as yet been extended. If a circle be drawn near our feet, and within that part of the ground which always appears level to us, it will always appear to be a circle, and at a very confiderable diHance it will appear an el- lipfe; but between thofe two fituations, it will not ap¬ pear to be either the one or the other, but will be like one of thofe ovals of Defcartes, which is more curved on one of its fides than the other. On thefe principles a parterre, which appears di- Horted when it is feen in a low fituation, appears per- fedly regular when it is viewed from a balcony oc any other eminence. Still, however, the apparent ir¬ regularity takes place at a greater diHance, while the part that is near the fpedator is exempt from it. If AB, fig. 5. be the ground plane, and Ka be a per¬ pendicular, under the eye, the higher it is fituated, at O, to the greater diHance will T, the place at which the plane begins to have an apparent afeent along T^, be removed. All the varieties that can occur with refped to the vifible motion of objeds, are fuccindly fiimmed up by Dr Porterfield under 11 heads, with which we lhall prefent our readers. 1. An objed moving very fwiftly is not feen, unlefs it be very luminous. Thus a cannon-ball is not feen if it is viewed tranfverfely : but if it be viewed accord¬ ing to the line it deferihes, it may be feen, becaufe its pidure continues long pn the fame place of the retina; which, therefore, receives a more fenfible imprefiion from the objed. 2. A live coal fwung brifkly round in a circle ap¬ pears a continued circle of fire, becaufe the impreffions made on the retina by light, being of a vibrating, and confeqnently of a lading nature, do not prefently pe- rifh, but continue till the coal performs its whole cir¬ cuit, and returns again to its former place. 3. If two objeds, unequally diflant from the eye, move with equal velocity, the more remote one will appear the flower; or, if their celerities be propor¬ tional to their dillances, they will appear - qually fwift, 4. If two objeds, unequally diflant from the eye, move with unequal velocities in the fame diredion, their apparent velocities are in a ratio compounded of the dired ratio of their true velocities, and the reci- ' procal 5574 Apparent place, &c. of objefts. OPT procal one of their diflances from the eye. 5. A vilible objeft moving with any velocity appears to be at reft, if the fpace defcribed in the interval of one fecond be imperceptible at the diftance of the eye. Hence it is that a near objedt moving very flowly, as the index of a clock, or a remote one very fwiftly, as a planet, feems to be at reft. 6. An objed moving with any degree of velocity will appear at reft, if the fpace it runs over in a fe¬ cond of time be to its diftance from the eye as 1 to 1400. 7. The eye proceeding ftraight from one place to another, a lateral objeft, not too far off, whether on the right or left, will feem to move the contrary way. 8. The eye proceeding ftraight from one place to ano¬ ther, and being fenlible of its motion, diftant objeds will feem to move the fame way, and with the fame velocity. Thus, to a perfon running caftwards, the moon on his right hand appears to move the fame way, and with equal fwiftnefs; for, by reafon of its diftance, its image continues fixed upon the fame place of the retina, from whence we imagine that the objed moves along with the eye. 9. If the eye and the objed move both the fame way, only the eye much fwifter than the objed> the laft will appear to go backwards. 10. If two or more objeds move with the fame velo¬ city, and a third remain at reft, the moveable ones will appear fixed, and the quiefeent in motion, the contrary way. Thus clouds moving very fwiftly, their parts feem topreferve their fituation, and the moon to move the contrary way. x 1. If the eye be moved with great velocity, lateral objeds at reft appear to move the contrary way. Thus to a perfon fitting in a coach, and riding brifkly through a wood, the trees feem to retire the contrary way; and to people in a (hip, &c. the fhores feem to recede. At the conclufion of thefe obfervations, our author endeavours to explain another phenomenon of motion, which, though very common and well known, had not, as far as he knew, been explained in a fatisfac- tory m-’nner. It is this: If a perfon turns fwiftly round, without changing his place, all objeds about will feem to move round in a circle the contrary way; and this deception continues not only while the perfon himfelf moves round, hut, which is more furprifing, h alfo continues for fome time after he ceafes to move, when the eye, as well as the objed, is at abfo- lute reft. The reafon why objeds appear to move round the contrary way, when the eye turns round, is not fo dif¬ ficult to explain: for though, properly fpeaking, mo¬ tion is not feen, as not being in itfelf the immediate objed of fight; yet by the fight we eafily know when the image changes its place on the retina, and thence conclude that either the objed, the eye, or both, are moved. But by the fight alone we can never deter¬ mine how far this motion belongs to the objed, how far to the eye, or how far to both. If we imagine the eye at reft, we aferibe the whole motion to the objed, though it be truly at reft. If we imagine the objed at reft, we aferibe the whole motion to the eye, though it belongs entirely to the objed; and when ihe eye is in motion, though we are fenfible of its I C S. Part III. motion, yet, if we do not imagine that it moves fo Apparent fwiftly as it really does, we aferibe only a part of the place, &c. motion to the eye, and the reft of it we aferibe to the ofobje^s> objed, though it be truly at reft. This laft, he fays, is what happens in the prefent cafe, when the eye turns round; for though we are fenfible of the motion of the eye, yet we do not apprehend that it moves fo fall as it really does; and therefore the bodies about appear to move the contrary way, as is agreeable to experience. But the great difficulty ftill remains, viz. Why, after the eye ceafes to move, objeds fhould, for fome time, ftill appear to continue in motion, though their pidures on the retina be truly at reft, and do not at all change their place. This, he imagined, proceeds from a miftake we are in with refped to the eye, which, though it be abfolutely at reft, we neverthelefs conceive it as moving the contrary way to that in which it moved before; from which miftake, with re¬ fped to the motion of the eye, the objeds at reft will appear to move the fame way which the eye is ima¬ gined to move; and, confequently, will feeni to con¬ tinue their motion for fome time after the eye is at reft. M. Le Cat well explains a remarkable deception, by which a perfon fhall imagine an objed to be on the oppofite fide of a board, when it is not fo, and alfo inverted, and magnified. It is illuftrated by fig. 3. Plate in which D reprefents the eye, and CB a large CCXIV. black board, pierced with a fmall hole. E is a large white board, placed beyond it, and ftrongly illumi¬ nated; and d a pin, or other fmall objed, held be¬ twixt the eye and the firft board. In thefe circum- ftances, the pin ftiall be imagined to be at F, on the other fide of the board, where it will appear inverted, and magnified; becaufe what is in fad perceived, is the (hadow of the pin upon the retina; and the light that is (topped by the upper part of the pin coming from the lower part of the enlightened board, and that which is (topped by the lower part coming from the upper part of the board, the (hadow muft necef- farily be inverted with refped to the objed. There is a curious phenomenon relating to vifion, which fome perfons have aferibed to the infledion of light, but which Mr Melville explains in a very diffe¬ rent and very fimple.manner. When any opaque body is held at the diftance of three or four inches from the eye, fo that a part of fome more diftant luminous objed, fuch as the win¬ dow, or the flame of a candle, may be feen by rays paffing near its edge, if another opaque body, nearer to the eye, be brought acrofs from the oppofite fide, the edge of the firft body will feem to fwell out¬ wards, and meet the latter; and in doing fo will in¬ tercept a portion of the luminous objed that was fetn before. This appearance be explains in the following man¬ ner: Let AB, fig. 1. reprefent the luminous objed, to which the fight is direded, CD the more diftant opaque body, GH the nearer, and EF the diameter of the pupil. Join ED, FD, EG, FG, and produce them till they meet AB in K, N, M, and L. It is plain that the parts AN, MB, of the luminous objed cannot be feen. But taking any point a between N and K, and drawing aDd, fince the portion dF oi „ v • ;■ ■ v .;:a A_ Optics . Plate CCXIV'. 3 ^V- <$ . Part III. OPT Concavity the pupil is filled with light flowing from that point, ot the Sky. v;f,b]e. Any point b, between a and K, muft fill /"F, a greater portion of the pupil, and there¬ fore muft appear brighter. Again, any point c, be¬ tween b and K, muft appear brighter than b, becaufe it fills a greater portion ^F with light. The point K itfelf, and every other point in the fpace KL, muft appear very luminous, fince they fend entire pencils of rays EKF, ELF, to the eye; arid the vifible bright- nefs of every point from L towards M, muft decreafe gradually, as from K to N; that is, the fpaces KN, LM, will appear as dim ftiadowy borders, or fringes, adjacent to the edges of the opaque bodies. When the edge G is brought to touch the right line KF, the penumbras unite; and as foon as it reaches NDF, the above phenomenon begins; for it cannot pafs that right line without meeting feme line aT) d, drawn from a point between N and K, and, by inter¬ cepting all the rays that fall upon the pupil, render it invifible. In advancing gradually to the line KDE, it will meet other lines bT)f, cT>g, &c. and there¬ fore render the points b> c, &c. from N to K, fuccef- fively invifible; and therefore the edge of the fixed opaque body CD muft feem to fwell outwards, and cover the whole fpace NK; while GH, by its motion, covers MK. When GH is placed at a greater diftance from the eye, CD continuing fixed, the fpace OP to be paired over in order to intercept NK is kfs; and therefore, with an equal motion of GH, the apparent fwelling of CD muft be quicker; which is found true by experience. If ML reprefent a luminous objeft, and REFQ^ any plane expofed to its light, the fpace FQ_will be entirely fhaded from the rays, and the fpace FE will be occupied by a penumbra, gradually darker, from E to F. Let now GH continue fixed, and CD move parallel to the plane EF; and as foon as it paffes the line LF, it is evident that the Ihadow QF will feem to fwell outwards; and when CD reaches klE, fo as to cover with its Ihadow the fpace RE, QF, by its extenfion, will cover FE. This is found to hold true likewife by experiment. ^ if. Of the Concave Figure of the Sky. Extent of This apparent concavity is only an optical decep- the vifible tion founded on the incapacity of our organs of vifion apianeflir-*0 ta^e *n very ^arSe diftances.—Dr Smith, in his face. Complete Syftem of Optics, hath demonftrated, that, if the furface of the earth was perfeftly plane, the di¬ ftance of the vifible horizon from the eye would fcarce exceed the diftance of 5000 times the height of the eye above the ground, fuppofing the height of the Plate eye between five and fix feet: beyond this diftance, CCX1V. all objefts would appear in the vifible horizon. For, 4* let OP be the height of the eye above the line PA drawn upon the ground ; and if an objeft AB, equal in height to PO, be removed to a diftance PA equal to 5O00 times that height, it will hardly be vifible by reafon of the fmallnefs of the angle AOB. Confe- quently any diftance AC, how great foever, beyond A, will be invifible. For fince AC and BO are parallel, the ray CO will always cut AB in fome point D between A and B ; and therefore the angle AOC, or AOD, will always be lefs than AOB, and Vol. VIIL ICS. . 5567 therefore AD or AC will be invifible. Conftcpiently Concavity all objedls and clouds, as CE and EG, placed at allt)f the sky diftances beyond A, if they be high enough to be vifible, or to fubtend a bigger angle at the eye than AOB, will appear at the horizon AB ; becaufe the diftance AC is invifible. ,3J Hence, if we fuppofe a vaft long row of obje&s, or Why a very a vaft long wall ABZ/, built upon this plane, and long row its perpendicular diftance OA from the eye at O to”1^* ^ be equal to or greater than the diftance O a of the cjialia!., vifiblethorizon', it will not appear ftraight, but circular, Fig i as if it was built upon the circumference of the horizon acegy : and if the wall be continued to an immenfe diftance, its extreme parts YZ, will appear in the horizon atyz, where it is cut by a line Oy pa¬ rallel to the wall. For, fuppofing a ray YO, the angle Y O^ will become infenfibly fmall. Imagine this infinite plane OAYy, with the wall upon it, to be turned about the horizontal line O like the lid of a box, till it becomes perpendicularto the other half of the horizontal plane L M^', and the wall parallel to it, like a vaft ceiling over head; and then the wail will appear like the concave figure of the clouds over-head. But though the wall in the horizon appear in the figure of a femicircle, yet the ceiling will not, but • much flatter. Becaufe the horizontal plane was a vifible furface, which fuggefted the idea of the fame diftances quite round the eye : but in the vertical plane extended between the eye and the ceiling, there is nothing that affe&s the fenfe with an idea of its parts but the common line ; confi^quently the apparent diftances of the higher parts of the ceiling will be gra¬ dually diminiftied in afeending from that line. Now when the fky is quite overcaft with clouds of equal gravities, they will all float in the air at equal heights above the earth, and confequently will compofe a fur- face refembling a large ceiling, as flat as the vifible fnrface of the earth. Its concavity therefore is not real, but apparent: and when the heights of the clouds are unequal, fince their real lhapes and magni¬ tudes are all unknown, the eye can feldom diftinguifti the unequal diftances of thofe clouds that appear in the fame diredlions, unlefs when they are very near us, or are driven by contrary currents of the air. So that the vifible fhape of the whole furface remains alike in both cafes. And when the fky is either partly over¬ caft, or perfeftly free from clouds, it is matter of fa& that we retain much the fame idea of its concavity as when it was quite overcaft. 13S The concavity of the heavens appears to the eye, f.hc which is the only judge of an apparent figure, to be lefs portion of a fpherical Fn-face than a hemifphere. appears lefs Dr Smith fays, that the centre of the concavity is much than a he- below the eye ; and by taking a medium among feveral mifphere. obfervations, he found the apparent diftance of its parts at the horizon to be generally between three and four times greater than the apparent .diftance of its parts overhead. For let the arch ABCD reprefent Fig. tf, the apparent concavity of the Iky, O the place of the eye, OA and OC the horizontal and vertical apparent diftances, whofe proportion is required. Firft obferve when the fun or the moon, or any cloud or ftar, is in fiuch a pofition at B, that the apparent arches BA, BC, extended on each fide of this obje& towards the 2 31 M horizon 5568 OPT Blue colour horizon and zenith, feem equal to the eye; then ofjhe^ky. taking the altitude of the objedf B with a quadrant, or a crofs-ftaff, or finding it by aftronomy from the given time of obfervation, the angle AOB is known. Drawing therefore the line OB in the pofition thus determined, and taking in it any point B at plea- fure in the vertical line CO produced downwards, feek the centre E of a circle ABC, whofe arches BA, BC, intercepted between B and the legs of the right angle AOC, fiiall be equal to each other; then will this arch ABCD reprefent the apparent figure of the Iky. For by the eye we eftimate the diftance between any two objefts in the heavens by the quantity of fky that appears to lie between them; as upon earth we eftimate it by the quantity of ground that lies be¬ tween them. The centre E may be found geometri¬ cally by conftru&ing a cubic equation, or as quick and fufficiently exadl hy trying whether the chords BA, BC, of the arch ABC drawn by conje&ure are equal, and by altering its radius BE till they are fo. Now in making feveral obfervations upon the fun, and fome others upon the moon and ftars, they feemed to our author to bifedt th? vertical arch ABC at B, when their apparent altitudes or the angle AOB was about 23 degrees; which gives the proportion of OC to OA as 3 to 10 or as 1 to 3-j- nearly. When the fun was but 30 degrees high, the upper arch feemed always lefs than the under one ; and, in our author’s opinion, always greater when the fun was about 18 or 20 de¬ grees high. § 5- Of the Blue Colour of the fky, and of Blue and Green Shadows. ©pinions The opinions of ancient writers concerning the co- cients'c”* lour of the Iky merit no notice. The firft who gave C)en s’ c‘ any rational explanation was Fromondus. By him it was fuppofed, that the bluenefs of the Iky proceeded from a mixture of the white light of the fun with the black fpace beyond the atmofphere, where there is neither refraftion nor refleftion. This opinion pre¬ vailed very generally even in modern times, and was maintained by Otto Guerick and all his cotemporaries, who afferted that white and black may be mixed in Juch a manner as to make a blue. Mr Bouguer had recourfe to the vapours diffufed through the atmo¬ fphere, to account for the refle&ion of the blue rays rather than any other. He feems however to fuppofe, that it arifes from the conftitution of the air itfelf, whereby the fainter coloured rays are incapable of making their way through any confiderable tradl of it. Hence he is of opinion, that the colour of the air is properly blue; to which opinion Dr Smith feems alfo 139 to have inclined. ^owTob*" ^ l^'s k*uc co1°ur of the fky is owing the appear ferved by ance an<^ green fhadows in the mornings and M. Buffon. evenings.'—Thefe were firft taken notice of by M. Buffon in the month of July 1742, when he obferved that the fhadows of trees which fell upon a white wall were green. He was at that time ftanding upon an eminence, and the fun was fetting in the cleft of a mountain, fo that he appeared confiderably lower than the horizon. The fky was clear, excepting in the -weft, which, though free from clouds, was lightly fhaded with vapours, of a yellow colour, inclining to red. Then the funJtfelf was exceedingly red, and was I C S. Part III. feemingly, at leaft, four times as large as he appears Blue colour to be at mid-day. In thefe circumftances, he fawof t^ie very diftinftly the fhadows of the trees, which were 30 or 40 feet from the white wall, coloured with a light green, inclining to blue. The fhadow of an ar¬ bour, which was three feet from the wall, was ex¬ actly drawn upon it, and looked as if it had been newly painted with verdegrife. This appearance lafted near five minutes ; after which it grew fainter, and vanifhed at the fame time with the light of the fun. 139 The next morning, at fun rife, he went to obferve ®lne An¬ other fhadows, upon another white wall ; but *nftead of finding them green, as he expe&ed, be obfervedbim. that they were blue, or rather of the colour of lively indigo. The fky was ferene, except a flight covering of yeilowifli vapours in the eaft ; and the fun arofe be¬ hind a hill, fo that it was elevated above his horizon. In thefe circumftances, the blue fhadows were only vi- fible three minutes; after which they appeared black, and in the evening of fame day he obferved the green fhadows exa&ly as before. Six dayspafled without his being able to repeat his obfervations, on account of the clouds; but the 7th day, at fnn-fet, the fhadows were not green, but of a beautiful fky-blue. He alfo obfer¬ ved, that the fky was, in a great meafure, free from va¬ pours at that time ; and that the fun fet behind a rock, fo that it difappeared before it came to his horizon. Afterwards he often obferved the fhadows both at fun- rife and fun-fet; but always obferved them to be blue, though with a great variety of fliades of that colour. He fhewed this phenomenon to many of his friends, who were as much furprifed at it as he himfelf had been; but he fays that any perfon may fee a blue fha¬ dow, if he will only hold his finger before a piece of white paper at fun-rife or fun-fet. t4;) ! The firft perfon who attempted to explain thisphe-Explana- nomenon was the Abbe Mazeas, in a memoir of thetion of th® 1 fociety in Berlin for the year 1752. He °bferved, that when an opaque body was illuminated by theAbbe moon and a candle at the fame time, and the two Mazeas. fhadows were caft upon the fame white wall, that which was enlightened by the candle was reddifh, and that which was enlightened by the moon was blue. But, without attending to any other circumftances, he fuppofed the change of colour to be occafionedby the diminution of the light; but M. Melville, and M. Bouguer, both independent of one another, feem to have hit upon the true caufe of this curious appear- i4t ance, and which hath been already hinted at. The for- Melville’s mer of thefe gentlemen, in his attempts to explain the ’d i5011." blue colour of the fky, obferves, that fince it is cer- pi^nation. tain that no body affumes any particular colour, but becaufe it refleds one fort of rays more abundantly than the reft ; and fince it cannot be fuppofed that the conftituent parts of pure air are grofs enough to fepa- rate any colours of themfelves ; wemuft conclude with Sir Ifaac Newton, that the violet and blue making rays are refleded more copioufly than the reft, by the finer vapours diffufed through the atmofphere, whofe parts are not big enough to give them the appearance of vilible opaque clouds. And he fhews, that in proper circumftances, the bluilh colour of the fky-light may be adually feen on bodies illuminated by it, as, he fays, it is objeded fhould always happen upon this hy- pothefis. For that, if on a dear cloudlefs day a fheet Partlll. OPT Blue colour of white paper be expofed to the fun’s beams, when of the Sky.any opaque body is placed upon it, the fhadow which is illuminated by the Iky only will appear remarkably bluilh compared with the reft of the paper, which re- 141 ceives the fun’s diredl rays. M. Begue- M. Beguehn, who has taken the moft pains with nationTf^thi8 fubgeft, obferves, that as M. Buffon mentions the the'greeti lhadows appearing green only twice, and that at all thadows. other times they are blue, this is the colour which they regularly have, and that the blue was changed into green by fome accidental circumftance. Green, he fays, is only a compofition of blue and yellow, fo that this accidental change may have arifen from the mixture of fome yellow rays in the blue fhadow; and that perhaps the wall might have had that tinge, fo that the blue is the only colour for which a general reafon is required. And this, he fays, muft be derived from the colour of pure air, which always appears blue, and which always refle&s that colour upon all ©bje&s without diftin&ion ; but which is too faint to be perceived when our eyes are ftrongly affc&ed by the light of the fun, refle&ed from other objefts around us. To confirm this hypothefis, he adds fome curious ©bfervations of his own, in which this appearance is agreeably diverfified. Being at the village of Boucholtz in July 1764, he obferved the fhadows proje&ed on the ,43 white paper of his pocket-book, when the fky was clear. Some cu- At half an hour paft 6 in the evening, when the fun was rious phe- about four degrees high, he obferved that the fhadow ~0b-°f his finger was of a dark grey, while he held the him. paper oppofite to the fun ; but when he inclined it al- moft horizontally, the paper had a bluifh caft, and the fhadow upon it was of a beautiful bright blue. When his eye was placed between the fun and the paper laid horizontally, it always appeared of a bluifh caft ; but when he held the paper, thus inclined, be¬ tween his eye and the fun, he could diftinguifh, upon every little eminence occafioned by the inequality of the furface of the paper, the principal of the prifma- tic colours. He alfo perceived them upon his nails, and upon the fkin of his hand. This multitude of co¬ loured points, red, yellow, green, and blue, almoft ef¬ faced the natural colour of the objefts. At three quarters paft fix, the fhadow’s began to be blue, even when the rays of the fun fell perpendicu¬ larly. The colour was the moft lively when the rays fell upon it at an angle of 450 degrees; but with a lefs inclination of the paper, he could diftinftly perceive, that the blue fhadow had a border of a ftronger blue, on that fide which looked towards the fky, and a r^d border on that fide which was turned towards the earth. To fee thefe borders, the body that made the fhadow was obliged to be placed very near the paper; and the nearer it was, the more fenfible was the red border. At the diftance of three inches, the whole fhadow was blue. At every obfervation, after having held the paper towards the fky, he turned it towards the earth, which was covered with verdure; holding it in fuch a manner, that the fun might fliine upon it while it received the fhadows of various bodies, but, in this pofitfon, he could never perceive the fhadow to be blue or green at any inclination with refpeft to the fun’s rays. At feven o’clock, the fun being ftill about two de- ! C S. 5569 grees high, the fhadows were of a bright blue, even Blue colofar when the rays fell perpendicularly upon the paper, butof the were the brighteft when it was inclined at an angle of 450. At this time he was furprifed to obferve, that a large trad of fky was nut favourable to this blue co¬ lour, and that the fhadow falling upon the paper placed horizontally was not coloured, or atleaft the blue was very faint. This Angularity, he concluded, arofefrom the fmall difference between the light of that part of the paper which received the rays of the fun, and that which was in the (hade in this fituation. In a fitua- tion precifely horizontal, the difference would vanifh, and there could be no fhadow. Thus too much or too little of the fun’s light produced, but for different rea- fons, the fame effed ; for they both made the blue light reflefted from the fky to become infenfible. This gentleman never faw any green fhadows, but when he made them fall on yellow paper. But he does not abfolutely fay, that green fhadows cannot be produ¬ ced in any other manner; and fuppofes, that if it was on the fame wall that M. Buffon faw the blue fha¬ dows, feven days after having feen the green ones, he thinks that the caufe of it might be the mixture of yellow rays, reflefted from the vapours, which he ob¬ ferves were of that colour. 144 Thefe blue fhadows, our author obferves, are not Blue ftia- confined to the times of the fun-rifing and fun-fetting;dowfis “i* on the 19th of July, when the fun has the greateft^" force, he obferved them at three o’clock in the af- ings and ternoon, but the fun (hone through a mift at thate»enings* time. If the (Icy is clear, the fhadows begin to be blue; when, if they be proje&ed horizontally, they are eight times as long as the height of the body that produces them, that is, when the centre of the fun is 70 8' a- bove the horizon. This obfervation, he fays, was made in the beginning of Auguft. Befides thefe coloured fhadows, which are produced by the interception of the diredl rays of the fun, our author obferved others fimilar to them at ever hour of the day, in rooms into which the light of the fun wag refledled from fome white body, if any part of the clear fky could be feen from the place, and all unne- ceffary light was excluded as much as poffible. Ob- ferving thefe precautions, he fays that the blue fha¬ dows may be feen at any hour of the day, even with the diredl light of the fun ; and that this colour will difappear in all thofe places of the fhadow from which the blue flcy cannot be feen. All the obfervations that our author made upon the yellow or reddifh borders of fhadows above-mention¬ ed, led him to conclude, that they were occafioned by the interception of the fky-light, whereby part of the fhadow was illuminated either by the red rays reflec¬ ted from the clouds, when the fun is near the horizon, or from fome terreftrial bodies in the neighbourhood. This conjedlure is favoured by the neeeflity he was under of placing any body near the paper, in order to produce this bordered fhadow, as he fays it is eafily demonflrated, that the interception of the fky-light can only take place when the breadth of [he opaqne body is to its diftance from the white ground on which the fhadow falls, as twice the fine of half the ampli- tu - ■ of the fky to its cofine. J4j At the conclufion of his obfervations on thefe blue Anolher 31 M 2 fhadotvs,kmd’ 557° OPT Irradiations fhadows, he gives a (hort account of another kind of ^ S^cs them, which, he does not doubt, have the fame ori- g ’ igin. Thefe he often faw early in the fpring when he was reading by the light of a candle in the morning, and confequently the twilight mixed with that of his candle. In thefe circumftances, the fhadow that was made by intercepting the light of his candle, at the di¬ ll ance of about fix feet, was of a beautiful and clear blue, which became deeper as the opaque body which made the fhadow was brought nearer to the wall, and was exceedingly deep at the diftance of a few inches only. But wherever the day-light did not «ome, the fhadows were all black without the lead mixture of blue. § 6. 0/ the Irradiations of the Sun’s Light appearing through the interfices of the Clouds. This is an appearance which every one muft have obferved when the fky was pretty much overcaft with clouds at fome diftance from each other. At that time feveral large beams of light, fomething like the appear¬ ance of the light of the fun admitted into a fmoky room, will be feen, generally with a very confiderable degree of divergence, as if the radiant point was fi- tuated at no great diftance above the clouds. Dr Smith obferves, that this appearance is one of thofe which ferve to demonftrate that very high and remote obje&s in the heavens do not appear to us in their real fliapes and pofitions, but according to their perfpe&ive projections on the apparent concavity of the fky. He acquaints us, that though thefe beams are generally rrxiv feen c,iverg'nS’ as reprefented in fig. 7. it is not al- ccx v< ways the cafe. He himfelf, in particular, once faw 146 _ them converging towards a point diametrically oppo- irradiation^ t0 the flin : for> as Iiear as he could conjefture, the obferved byPoint t0 which they converged was fituated as much Dr Smith, below the horizon, as the fun was then elevated above the line tY)t> and the point below it in oppofition to the fun is E; towards which all the beams vt, vt, &c. j47 appeared to converge. Thepheno- “ Obferving, (fays our author,) that the point of "hined^b conve,'Sence was oppofite to the fun, I began to fufpeft -'.tame ythat this unufua! phenomenon was but a cafe of the ufual apparent divergence of the beams of the fun from his appai-ent place among the clouds, as reprefented in fig. 7. I fay, an apparent divergence; for though no¬ thing; is more common than for rays to diverge from a luminous, body, yet the divergence of thefe beams in fuch large angles is not real but apparent. Becaufe it is impofiible for the direCt rays of the fun to crofs one another at any point of the apparent concavity of the fky, in a greater angle than about half a degree. For the diameter of the earth being fo extremely final], in comparifon to the diftance of the fun, as to fubtend ah angle at any point of his body of but 20 or 22 feconds at molt; and the diameter of ourvifible horizon being extremely fmaller than that of the earth ; it is plain, that all the rays which fall upon the horizon, from any given point of the fun, muft be inclined to each other in the fmalieft angles imaginable ; the greateft of them being as much fmaller than that angle of 22 feconds, as the diameter of the vifible horizon is fmaller than that of the earth. All the rays that come to us from any given point of the fun piay therefore be cOnfuK - ICS. Partin. ed as parallel to each other; as the rays from the irradiations point e, or ffth from the oppofite point f; and con- LVhrS&cS fequently the rays of thefe two pencils that come from lg * c* oppofite points of the fun’s real diameter, and crofs each other in the fun’s apparent place B among the clouds, can conftitute no greater an angle with each other than about half a degree; this angle of their interfec- tion e B/"being the fame as the fun would appear un¬ der to an eye placed among the clouds at B, or (which is much the fame), to an eye at O upon the ground. Becaufe the fun’s real diftance OS is inconceivably greater than his apparent diftance OB. Therefore the rays of the fun, as B^, B^, do really diverge from his apparent place B in no greater angles^B^ than about half a degree. Neverthelefs they appear to diverge from the place B in all poffible angles, and even in op- Fig. 7* pofite dire&ions. Let us proceed then to an explana¬ tion of this apparent divergence, which is not felf-evi- dent by any means; though at firft fight we are apt to think it is, by not diftinguilhing the vaft difference between the true and apparent diftances of the fun. “ What I am going to demonftrate is this. Sup- pofing all the rays of the fun to fall accurately paral¬ lel to each other upon the vifible horizon, as they do very nearly, yef in both cafes they muft appear to di¬ verge in all poffible angles. Let us imagine the hea¬ vens to be partly overcaft with a fpacious bed of bro¬ ken clouds, v, v, v, &c. lying parallel to the plane ofp. ^ the vifible horizon, here reprefented by the line AOD. S' And w'hen the fun’s rays fall upon thefe clouds in the parallel lines sv, sv, See. let fome of them pafs through their intervals in the lines vt, vt, See. and fall upon the plane of the horizon at the places t, t, Sec. And fince the reft of the incident rays sv, sv, are fuppofed to be intercepted from the place of the fpe&ator at O by the cloud x, and from the intervals between the tranfmitted rays vt, vt. Sec. by the clouds v, v, Sec. a fmall part of thefe latter rays vt, vt, when refle&ed every way from fome certain kind of thin vapours float¬ ing in the air, may undoubtedly be fufficient to affeft the eye with an appearance of lights and fliades, in the form of bright beams in the places W, v t, Sec. and of dark ones in the intervals between them: juft as the like beams of light and fliade appear in a room by reflexions of the fun’s rays from a fmoky or dufty air within it: the lights and fliades being here occa- fioned by the tranfmiffion of the rays through fome parts of the window, and by their interruption at other parts. “ Now if the apparent concavity of this bed of clouds v, v, to the eye at O, be reprefented by the arch ABCD, and be cut in the point B by the line OB.v drawn parallel to the beams tv; it will be evident by the rules of perfpedlive, that thefe long beams will not appear in their real places, but upon the concave AB CD diverging every way from the place B, where the fun himfelf appears, or the cloud x that covers his body, as reprefeut' d feparately in full view in fig. 7. “ And for the fame reafon, if the line BO be pro¬ duced towards E, below the plane of the horizon AOD, and the eye be dlrefted towards the region of the Iky direftly above E, the lower ends of the fame real beams vt, vt, will now appear upon the part DF of this concave; and will feem to converge towards the point Fij inuaud juft ad much below the horizon as the op¬ pofite OPTICS . Plate CCXV Part III. OPT Irradiations pofite point B is above it: which is feparately repre- of the Sun’s fente<] ;n full v;evv jn flgt g. g 'r* c’ “ For if the beams vt, vt, be fuppofed to be vifible throughout their whole lengths, and the eye be direc¬ ted in a plane perpendicular to them, here reprefented by the line OF; they and their intervals will appear broadeft in and about this plane, becaufe thefe parts of them are the neared to the eye; and therefore their remoter parts and intervals will appear gradually nar¬ rower towards the oppofite ends of the line BE. As a farther illudration of this matter, we may conceive the fpeftator at O to be fnuated upon the top of fo large a defcent OHI towards a remote valley IK, and the fun to be fo very low, that the point E, oppofite to him, may be feen above the horizon of this (hady valley. In this cafe it is manifed, that the fpeftators at O would now fee thefe beams converging fo far as to 148 meet each other at the point E in the Iky itfelf. ved'*' ^ n0t reniem^er to ^ave ever ^een any pheno- mooi/lieht menon by moon-light; not fo much as of beams diverging from her apparent place. Probably her light is too weak after reflexions from any kind of vapours, to caufe a fenfible appearance of lights and (hades fo as to form thefe beams. And in the unufual phenomenon I well remember, that the converging fun-beams towards the point below the horizon were not quite fo bright and drong as thofe ufually are that diverge from him; and that the Iky beyond them ap¬ peared very black (feveral (howers having pafled that way), which certainly contributed to the evidence of this appearance. Hence it it is probable that the thin- nefs and weaknefs of the refleXed rays from the va¬ pours oppofite to the fun, is the chief catife that this appearance is fo very uncommon in comparifon to that other of diverging beams. For as the region of the Iky round about the fun, is always brighter than the oppofite one ; fo the light of the diverging beams ought alfo to be brighter than that of the converging ones. For, though rays are refleXed from rough un- polifhed bodies in all pofiible direXions, yet it is a ge¬ neral obfervation, that more of them are refleXed for¬ wards obliquely, than are refleXed more direXly back¬ wards. Befides, in the prefent cafe, the incident rays upon the oppofite region to the fun, are more dimi- nifhed by continual refleXions from a longer traX of the atmofphere, than the incident rays upon the region 149 next the fun. More fre- «< -phe common phenomenon of diverging.beams, I furmner th»nk> 13 m°re frequent in fummer than in winter, and than in alfo when the fun is lower than when higher up; pro- winter. bably becaufe the lower vapours are denfer and there¬ fore more ftrongly refltXive than the higher ; be¬ caufe the lower iky-lightis not fo bright as the upper; becaufe the air is generally quieter in the morn¬ ings and evenings than about noon-day; and laltly, becaufe many forts of vapours are exhaled in greater plenty in fummer than in winter, from many kinds of volatile vegetables; which vapours, when the air is cooled and condenfed in the mornings and evenings, may become denfe enough to refleX a fenfible light.” §7-0/ the Illumination of the Shadow of the Earth by ■ the refraflion of the Atmofphere. The ancient philofophers, who knew nothing of the refraXive power of the atmofphere, were very much perplexed to account for the body of the moon being ICS. 5571 vifible when totally eclipfed. At fuch times fhe gene- lHumina- rally appears of a dull red colour, like tarniflied C0P* g3”t£>fsthfr per, or of iron almoft red hot. This, they thought, was the moon’s native light, by which (he became vi fible when hid from the brighter light of the fun. Plutarch indeed, in his difeourfe upon the face of the moon, attributes this appearance to the light of the iio fixed ftars refleXed to us by the moon; but this muftExplained be by far too weak to produce that effeX. The trueg^1|^ caufe of it is the fcattered beams of the fun bent into53"11 the earth’s fttadow by refraXions through the atmo¬ fphere in the following manner. “ Let the body of the fun, fays Dr Smith, be repre- Plate fented by the greater circle a b, and that of the earth by CCXV. the leffer one c d; and let the lines ace and b de touch Ia them both on their oppofite fides, and meet in e beyond the earth ; then the angular fpace ced will reprefent the conic figure of the earth’s fhadow, which would be to¬ tally deprived of the fun’s rays, were none of them bent into it by the refraXive power of the atmofphere. Let this power juft vanifh at the circle hi, concentric to the earth, fo that the rays ah and hi, which touch its oppofite fides, may proceed unrefraXed, and meet each other at k. Then the two neareft rays to thefe that flow within them, from the fame points a and b, being refraXed inwards through the margin of the at- mofphere, will crofs each other at a point /, fomewhat nearer to the earth than k; and in like manner, two oppofite rays next within the two laft will crofs each other at a point m, fomewhat nearer to the earth than /, having fuffered greater refraXions, by palling thro’ longer and denfer traXs of air lyii^* fomewhat nearer to the earth. The like approach of the fucceflive in- terfeXions k, /, m, is to be underftood of innumerable couples of rays, till you come to the interfeXion n of the two innermoft ; which we may fuppofe juft to touch the earth at the points oand />. It is plain then, that the fpace bounded by thefe rays on, np, will be the only part of the earth’s (hadow wholly deprived of the fun’a rays. Let reprefent part of the moon’s orbit when it is neareft to the earth, at a time when the earth’s dark (hadow onp\% the longed : in this cafe I will (hew that the ratio of tm to tn is about 4 to 3; and confequently that the moon, tho’ centrally eclip¬ fed at m, may yet be vifible by means of thofe fcatter¬ ed rays above-mentioned, firft tranfmitted to the moon by refraXion through the atmofphere, and from thence refleXed to the earth. “ For let the incident and emergent parts aq, r«, of the ray aqorn, that juft touches the earth at 0, be produced till they meet at u, and let <7 y « produced meet the axis // produced in x; and joining us and u m, fince the refraXions of an horizontal ray pafling from 0 to r, or from 0 to q, would be alike and equal, the external angle nux is double the quantity of the ufual refraXion of an horizontal ray ; and the angle aus is the apparent meafure of the fun’s femidiameter feen from the earth ; and the angle ust is that of the earth’s femidiameter tu feen from the fun (called his horizon¬ tal parallax); and laftly, the angle umt is that of the earth’s femidiameter feen from the moon, (called her horizontal parallax); becaufe the elevation of the point u above the earth, is too fmall to make a fenfible er¬ ror in the quantity of thefe angles; whole meafures by aftronomical tables are as follow; The S572 Illumina¬ tion of the Earth’s Shadow.

It is eafy to colleft from the moon’s greateft horizontal parallax of 62'—10", that her leaft diftarvce tm is about 55I- femidiameters of the earth; and therefore the greateft length of the dark fhadow, being three quarters of tm, is about 414 fe- midiamettrs. “ The difference of the laft mentioned angles tnu, tmu, is murr=-2\', that is, about two thirds of 31'— 40", the angle which the whole diameter of the fun fubtends at a. Whence it follows, that the middle point in of the moon centrally eclipfed, is illuminated by rays which come from two thirds of every diameter of the fun’s difk, and pafs by one fide of the earth; and alfo by rays that come from the oppofite two thirds of every one of the faid diameters, and pafs by the other fide of the earth. This will appear by conceiving the ray aqorn to be inflexible, and its middle point 0 to Bide upon the earth, while the part rn is approaching to touch the point m; for then the oppofite part qa will trace over two thirds of the fun’s diameter. The true proportion of the angles num,aus, could not be preferred in the fcherne, by reafon of the fun’s im- menfe diftance and magnitude with refpeft to the earth. Having drawn the line at*, is is obfervable, that all the incident rays, as aq, «*, flowing from any one point of the fun to the circumference of the earth, will be colle&ed to a focus «, whofe diftance t“ is lefs than tm in the ratio of 62 to 67 nearly; and thus an image of the fun will be formed at «/?, whofe rays will di¬ verge upon the moon. For the angle t«.u is the dif¬ ference of the angles xu*, u«t found above; and to. : tm :: ang. tmu : ang. t*u :: 62'—16" : 67—30". “ The rays that flow next above aq and a*., by paffing through ja thinner part of the atmofphere, will be united at a point in the axis at* fomewhat farther from the earth than the laft focus «; and the fame may be faid of the rays that pafs next above thefe, and fo on ; whereby an infinite feries of images of the fun will be formed, whofe diameters and degrees of bright- nefs will increafe with their diftances from the earth. Hence it is manifeft why the moon eclipfed in her >n ap- perigee is obferved to appear always duller and dark- pears dullerer ;n fop,, apogee. The reason why her colour is fclTin herF'a'W3ys l^e c0PPer k'nt* between a dull red and perigee orange, I take to be this. The blue colour of a clear than in herfky fhews manifeftly that the blue-making rays are more copioofly refleded from pure air than thofe of any other colour; confequently they are lefs copioufly tranfmitted through it among the reft that come from the fun, and fo much the lefs as the traft of air thro’ which they pafs is the longer. Hence the common co¬ lour of the fun and moon is whiteft in the meridian, and grows gradually more inclined to diluted yellow, Why the .apogee. = ang. tnu — 83—10 parallax = ang. tmu — 62—to orange, and red, as they defcend lower, that is, as the rays are tranfmitted through a longer traft of air ; which tradt being ftill lengthened in palling to the moon and back again, caufes a ftill greater lofs of the blue-making rays in proportion to the reft ; and fo the refulting colour of the tranfmitted rays mull lie be¬ tween a dark orange and red, accoiding to Sir Ifaac Newton’s rule for finding the refult of a mixture of colours. We have an inftance of the reverfe of this cafe in leaf-gold, which appears yellow by refle&ed, and blue by tranfmitted rays. The circular edge of the (hadow in a partial eclipfe appears red; becaufe the red-making rays are the leaft refracted of all others, and confequently are left alone in the conical furface of the lhadow, all the reft being refradted into it. § 8. Of the Meafures of Light. That fome luminous bodies give a ftronger, and others a weaker light, and that fome refledt more light than others, was always obvious to mankind; Mr Bou- but no perfon, before Mr Bouguer, hit upon a toler- guer’s co able method of afcertaining the proportion that twotrivances or more lights bear to one another. The methods he^or.niea* mod commonly ufed were the following. light? He took two pieces of wood or pafteboard EC and p| ^ CD, fig. 4. in which he made two equal holes PcCXV and over which he drew pieces of oiled or white paper. Upon thefe holes he contrived that the light of the different bodies he was comparing fhould fall; while he placed a third piece of pafteboard FC, to prevent the two lights from mixing with one another. Then placing himfelf fometimes on one fide, andfome- times on the other, but generally on the oppofite fide of this inftrument, with refpedt to the light, he alter¬ ed their polition till the papers in the two holes ap¬ peared to equally enlightened. This being done, he computed the proportion of their light by the fquares of the diftances at which the luminous bodies were placed from the objefts. If, for inftance, the diftan¬ ces were as three and nine, he concluded that the light they gave were as nine and eighty-one. Where any light was very faint, he fometimes made ufe of lenfes, in order to condenfe it; and he inclofed them in tubes or not, as his particular application of them required. To meafure the intenfity of light proceeding from the heavenly bodies, or reffe&ed from any part of the fky, he contrived an inftrument which rtfembles a kind of portable camera obfcura. He had two tubes, of which the inner was black, fattened at their lower extremities by a hinge C, fig. 5. At the bottom of thefe tubes were two holes, R and S, three or four lines in diameter, covered with two pie'es of fine'white paper. The two other extremities had each of them a circular aperture, an inch in diameter; and one of the tubes confifted of two, one of them Aiding into the Part III. OPT Meafures of the other, which produced the Tame effedl as varying the aperture at the end. When this inftrument is ufed, theobferver has his head, and the end of the in¬ ftrument C, fo covered, that no light can fall upon his eye, befides that which comes thro’ the two holes S and R, while an afliftant manages the inftrument, and draws out or fhortens the tube DE, as the obferver di- refls. When the two holes appear equally illumina¬ ted, the intenfity of the lights is judged to be inverfe- ly as the fquares of the tubes. In ufing this inftrument, it is neceflary that the ob- jedi (hould fubtend an angle larger than the aperture A or D, feen from the other end of the tube ; for, otherwife, the lengthening of the tube has no effeft. To avoid, in this cafe, making the inftrument of an inconvenient length, or making the aperture D too CCXV narrow« he has recourfe to another expedient. He conftruds an inftrument, reprefented fig. 6. confid¬ ing of two objeft-glafies, AE and DF, exaftly equal, fixed in the ends of two tubes fix or feven feet, or, in fome cafes, toor 12 feet long, and having their foci at the other ends. At the bottom of thefe tubes B, are two holes, three or four lines in diameter, covered with a piece of white paper; and this inftrument is ufed exactly like the former. If the two objedls to be obferved by this inftrument be not equally luminous, the light that iffues from them muft be reduced to an equality, by diminifhing the aperture of one of the objedt-glafies ; and then the re¬ maining furface of the two glaffes will give the propor¬ tion of their lights. But for this purpofe, the central parts of the glafs muft be covered in the fame propor¬ tion with the parts near the circumference, leaving the aperture fuch as is reprefented fig. 7. becaufe the middle part of the glafs is thicker and lefs tranfparent than the reft. If all the objedls to be obferved lie nearly in the fame direftion, our author obferves, that thefe two long tubes may be reduced into one, the two obje&- glafies being placed clofe together, and one eye-glafs fuffieing for them both. The inftrument will then be the fame with that of which he publifhed an ac¬ count in 1748, and which he called a heliometer, or I?5 aftrometer. There in- Our author obferves, that it is not the abfolute ftruments quantity, but only the intenfity of the light, that is onT^h6 • mea^ure^ by tbefe two inftruments, or the number of tcnLy of"' rays> *n proportion to the furface of the luminous bo- the light, dy 5 and it is of great importance that thefe two things be diftinguifhed. The intenfity of light may be very great, when the quantity, and its power of illumina- tfng other bodies, may be very fmall, on account of the fmallnefs of its furface ; or the contrary may be the cafe, when the furface is large. Having explained thefe methods which M. Bouguer took to meafure the different proportions of light, we fhall fubjoin in this place a few mifcellaneous examples of his application of them. It is obfervable, that when a perfon Hands in a place where there is a ftrong light, he cannot diftinguifh objefts that are placed in the (hade ; nor can he fee any thing upon going immediately into a place where there is very little light. It is plain, therefore, that the aflion of a ftrong light upon the eye, and alfothe imprefiion which it leaves upon it, makes it infenfible ICS. 5573 to the effe& of a weaker light. M. Bouguer had theMeafnres of curiofity to endeavour to afeertain the proportion be- -b’febc tween the intenfities of the two lights in this cafe; and by throwing the light of two equal candles upon a board, he found that the (hadow made by intercep¬ ting the light of one of them, could not be perceived by his eye, upon the place enlightened by the other, at little more than eight times the diftance ; from whence he concluded, that when one light is eight times eight, or 64 times lefs than another, its pre¬ fence or abfence will not be perceived. He allows, however, that the effect may be different on different eyes ; and fuppofes that the boundaries in this cafe, with refpedl to different perfons, may lie between 60 and 80. Applying the two tubes of his inftrnmenf, men¬ tioned above, to meafure the intenfity of the light re- fle&cd from different parts of the Iky ; he found, that when the fun was 25 degrees high, the light was four times ftronger at the diftance of eight or nine degrees from his body, than it was at 31 or 32 degrees. But what ftruckhim the moft was to find, that when the fun is 15 or 20 degrees high, the light decreafes oa the fame parallel to the horizon to 110 or 120 de¬ grees, and then increafes again to the place exaftly oppofite to the fun. The light of the fun, our author obferves, is too ftrong, and that of the ftars too weak, to determine the variation of their light at different altitudes : but Ss, in both cafes, it muft be in the fame proportion, with the diminution of the light of the moon in the fame circumftances, he made his obfervations on that luminary, and found, that its light at 190 16', is to its light at 66° 1T, as 1681 to 2500; that is, the one is nearly two thirds of the other. He chofe thofe 154 particular altitudes, becaufe they are thofe of the fun 9r<:at va" at the two folllices at Croific, where he then refided.^of When one limb of the moon touched the horizon ofthe moon the fea, its light was 2000 times lefs than at the alti-at different tude of 66° 11'. But this proportion he acknowledges akitu lle concerning compared each of them to that of a candle in a dark the light8 room, ooe in the day-time, and the other in the night of the following, when the moon was at her mean diftance moon. fr0m the earth; and, after many trials, he concluded that the light of the fun is about 300,000 times greater than that of the moon; which is fuch a difproportion, that, as he obferves, it can be no wonder that philo¬ fophers have had fo little fuccefs in their attempts to colled! the light of the moon with burning-glaffes. For the larged of them will not increafe the light 1000 times; which will dill leave the light of the moon, in the focus of the mirror, 300 times lefs than the inten- fity of the common light of the fun. To this account of the proportion of light which we adtually receive from the moon, it cannot be dif- pleafing to the reader, if we compare It with the quan¬ tity which would have been tranfmitted to us from that opaque body, if it refledted all the light it re¬ ceives. Dr Smith thought that he had proved, from two different confiderations, that the light of the full moon would be to our day-light as one to about 90,900, JS7 if no rays were lod at the moon. Dr Smith’s In the fird place, he fuppofes that the moon, en- cakulation. lightened by the fun, is as luminous as the clouds are at a medium. He therefore fuppofed the light of the fun to be equal to that of a whole hemifphere of clouds, or as many moons as would cover the furface of the heavens. But on this Dr Priedley obferves, that it is true, the light of the fun fhining perpendi¬ cularly upon any furface would be equal to the light „ refledted from the whole hemifphere, if every part re¬ fledted all the light that fell upon it; but tlie light that would in fadt be received from the whole hemi¬ fphere (part of it being received obliquely) would be only one-half as much as would be received from the whole hemifphere if every part of it fhone diredtly upon the furface to be illuminated. In his Remarks, par. 97, Dr Smith demondrates his method of calculation in the following manner: “ Let the little circle cfdg reprefent the moon’s CCXV k°fiy fialf enlightened by the fun, and the great circle 8. * a el, ^ fpherical fhell concentric to the moon, and touching the earth; a b, any diameter of that fhell per¬ pendicular to a great circle of the moon’s body, re- prefented by its diameter cd; e the place of the fhell receiving full moon light from the bright hemifphere f dg. Now, becatrfe the furface of the moon is rough like that of the earth, we may allow that the fun’s rays, incident upon any fmall part of it, with any ob¬ liquity, are refiedted from it every way alike, as if they were emitted. And therefore, if the fegment df fhone alone, the points a, e, would be equally illudrated by it; and likewife if the remaining bright fegment dg fhone alone, the points b e would be equally il- kidrated by it. Conftquently, if the light at the ICS. Part ml point a was increafed by the light at l, it would be- Meafure.# come equal to the full moon-light at e. And con- ceiving the fame transfer to be made from every point of the hemifpherical furface bbik to their oppofite points in the hemifphere kaeh, the former hemi¬ fphere would be left quite dark, and the latter would be uniformly illuftrated with full moon-light; arifing from a quantity of the fun’s light, which, immediately before its incidence on the moon, would uniformly il- luftrate a circular plane equal to a great circle of her body, called her dijk. Therefore the quantities of light being the fame upon both furfaces, the denfity of the fun’s .incident light, is to the denfity of full moon-light, as that hemilpherical furface bek is to the faid difk; that is, as any other hemifpherical fur- face whofe centre is at the eye, to that part of it which the moon’s diflt appears to poffefs very nearly, becaufe it fubtends but a fmall angle at the eye: that is, as radius of the hemifphere to the verfed fine of the moon’s apparent femidiameter, or as 10,000,000 to 1106— or as 90,400 to 1; taking the moon’s meaa horizontal diameter to be 16' 7". “ Striftly fpeaking, this rule compares moon-light at the earth with day-light at the moon; the medium of which, at her quadratures, is the fame as our day¬ light ; but is lefs at her full in the duplicate ratio of 365 to 366,' or thereabout; that is, of the fun’s di- ttances from the earth and full moon: and therefore fall-moon light would be to our day-light, as about 1 to 90,900, if no rays were loft at the moon. 1 Secondly, I fay that full-moon light is to any "L of the r other moon light as the whole diflc of the moon to the part that appears enlightened, confidered upon a plane furface. For now let the earth be at b, and let Fig. 5. d/be perpendicular to fg, and gtn to cd: then it is plain, that g l is equal to dm; and that^/ is equal to a perpendicular fedtion of the fun’s rays incident upon the arch dg, which at b appears equal to dm; the eye being unable to diftinguiih the unequal diftances of its parts. In like manner, conceiving the moon’s furface to confift of innumerable phyfical circles pa¬ rallel to cfdg, as represented at A, the fame reafon holds for every one of thefe circles as for cfdg. It follows then, that the bright part of the furface vifible at b, when reduced to a flat as reprefented at B, by the crefcent pdqmp, will be equal and fimilar to a perpendicular fedtion of all the rays incident on that part, reprefented at C by the crefcent pgqlp- Now the whole diflc being in proportion to this crefcent, as the quantities of light incident upon them; and the light falling upon every rough particle, being equally rarified in diverging to the eye at b, conlidered as equidiftaut from them alh; it fellows, that full moon¬ light is to this moon-light as the whole diflc pdqc to the crefcent pdqvip. “ Therefore, "by compounding this ratio with that in the former remark, day light is to moon-light as the furface of an hemifphere whofe centre is at the eye, to the part of that furface which appears to be poffeffed by the enlightened part of the moon. * Mr Miehell made his computation in a much more Mr Mi- fimple and eafy manner, and in which there is lefs danger of falling into any miftake. Confidering™ a lon‘ the diftance of the moon from the fun, and that the denfuy PartHI. OPT Of Optical denfity of the light muft decreafe in the proportion of Iaftrumeiust}ie fqUare 0f that diltance, he calculated the denfity p 0f lhe fun>s Ught, at that diftance, in proportion to its denfity at the furface of the fun and in this manner he found, that if the moon refle&ed all the light it re¬ ceives from the fun, it would only be the 45,000th part of the light we receive from the greater lumi- ; uary. Admitting, therefore, that moon light is only a 300,000th part of the light of the fun, Mr Michell concludes, that it reflects no more than between the 6th and 7th part of what falls upon it. Sect. IV. Of Optical Injlruments. . pia(e § 1. The Multiplying-glafs. . CCXVI. The multiplying-glafs is made by grinding down the round fide hik (fig. 1.) of a convex glafs AB, into feveral flat furfaces, as hbt bid, dk. An ob¬ ject C will not appear magnified when feen through this glafs by the eye at H; but it will appear multiplied into as many different objeds as the glafs contains plane furfaces. For, fince rays will flow from the objed C to all parts of the glafs, and each plane fur- face will refrad thefe rays to the eye, the fame objed will appear to the eye in the diredion of the rays which enter it through each furface. Thus, a ray gi H, falling perpendicularly on the middle furface, will go through the glafs to the eye without fuffering any refradion; and will therefore fhew the objed in its true place at C: whilft a ray ab flowing from the fame objed, and falling obliquely on the plane furface bh, will be refraded in the diredion be, by » pafiing through the glafs; and, upon leaving it, will go on to the eye in the diredion eH; which will caufe the fame objed C to appear alfo at E, in the diredion of the ray H e, produced in the right line Hen. And the ray c d, flowing from the objed C, and falling obliquely on the plane furface d k, will be refraded (by pafiing through the glafs, and leaving it at f) to the eye at H; which will caufe the fame objed to appear at D, in the diredion Hfm.—If the glafs be turned round the line glH, as an axis, the objed C will keep its place, becaufe the furface bld'vs not removed; but all the other objeds will feem to go round C, becaufe the oblique planes, on which the rays abed fall, will go round by the turning of the glafs. § 2. Mirrors. 1. The Plane Mirror, or common Looking-glafs. The image of any objed that is placed before a plane mirror, appears aS big to the eye as the objed itfelf; and is ered, diftind, and feetningly as far behind the mirror, as the objed is before it ; and that part of the mirror which refleds the image of the objed to the eye (the eye being fuppofed equally diftant from the glafs with the objed) is juft half as long and half as broad as.the I piate objed itfelf. Let AB (fig. 3.) be an objed placed CCXVT. before the refieding furface g h i of the plane mirror CD ; and let the eye be at 0. Let A/£ be a ray of light flowing from the top A of the objed and falling upon the mirror at h, and b in be a perpendicular to the furface of the mirror at h; the ray Ab will be re- fkded from the mirror to the eye at os making an angle >«A/j,?equal to the angle A h m: then will the Von. VIII. 1 ICS. . . SS7S top of the image E appear to the eye in the direc-Of Optical tion of the refleded ray oh produced to E, where theIaftrtlmcnir' right line A/> E, from the top of the objed, cuts the right line o/’E, at E. Let B/' be a ray of light pro¬ ceeding from the foot of the objed at B to the mirror at i; and ni a perpendicular to the mirror from the point i, where the ray B i falls upon it: this ray will be refleded in the line i0, making an angle w/o, equal the angle B i n, with that perpendicular, and enter¬ ing the eye at 0; then will the foot F of the image ap¬ pear in the diredion of the refleded ray oi, produced to F, where the right line BF cuts the refleded ray pro¬ duced to F. All the other rays that flow from the inter¬ mediate points of the objed AB, and fall upon the mirror between h and i, will be refleded to the eye at 0} and all the intermediate points of the image EF will appear to the eye in the diredion of thefe reflec¬ ted rays produced. But all the rays that flow from the objed, and fall upon the mirror above b, will be re¬ fleded back above the eye at c; and all the rays that flow from the objed, and fall upon the mirror be¬ low i, will be refleded back below the eye at 0 ; fo that none of the rays that fall above h, or below i, can be refleded to the eye at 0; and the diftance be¬ tween h and i is equal to half the length of the objed AB. l69 Hence it appears, that if a man fees his whole size of a image in a plane looking-glafs, the part of the glafslooking- that refleds his image muft be juft half as long andsbf5”1 half as broad as himfelf, let him Hand at any diftance wjq from it whatever ; and that his image muft appear juft fee his as far behind the glafs as he is before it. Thus, the man whole i- AB (fig 4.) viewing himfelf in the plane mirror CD,1*19^- which is juft half as long as himfelf, fees his whole image as at EF, behind the glafs, exadly equal to his own fize. For, a ray AC proceeding from his eye at A, and falling perpendicularly upon the furface of the glafs at C, is reflected back to his eye, in the fame line CA; and the eye of his image will appear at E, in the fame line produced to E, beyond the glafs. And a ray BD, flowing from his foot, and falling obliquely on the glafs at D, will be refleded as ob¬ liquely on the other fide of the perpendicular abT), in the diredion DA ; and the foot of his image will ap¬ pear at F, in the diredion of the refleded ray AD, produced to F, where it is cut by the right line BGF, drawn parallel to the right line ACE. Juft the fame as if the glafs were taken away, and a real man flood at F, equal in fize to the man {landing at B : for to his eye at A, the eye of the other man at E would be feen in the diredftion of the line ACE ; and the foot of the man at F would be feen by the eye A, in the diredion of the line ADF. If the glafs be brought nearer the man AB, as fup- pofe to c b, he will fee his image as at CDG : for the refleded ray CA (being perpendicular to thp glafs) will {hew the eye of the image as at C ; and the inci¬ dent ray B being refleded in the line b A, will ftiew the foot of his image as at G ; the angle of re- fledion ab A being always equal to the angle of inci¬ dence H>ba: and fo of all the intermediate rays from A to B. Hence, if the man AB advances towards the glafs CD, his image will approach towards it; and if he recedes from the glafs, his image will alfo recede from it. . 3»N If 5576 OPT Ot Optical If the objedl be placed before a common looking- Inftrnmentsg)af3< an(j v;eweci obliquely, three, four, or more images p. of it will appear behind the glafs. CCXII. To explain this, let ABCD (fig. n.) reprefent the glafs; and let EF be the axis of a pencil of rays flow- WhV'three ing from E, a point in an objeft fituated there. The or four i- rays of this pencil will in part be refle&ed at F, fup- mages of pofe into the line FG. What remains will (after re- cbjefls are fra(qjon at which we do not confider here) pafs on plane'mir- to ^ ’ ^rom wl161106 (on account of the quickfilver rors. which is fpread over the fecond furface of glafles of this kind to prevent any of the rays from being tranf- mitted there) they will be llrongly refledted to K, where part of them will emerge and enter an eye at L. By this means one reprefentation of the faid point will be formed in the line LK produced, fuppofe in M: Again, another pencil, whofe axis is E N, firft reflec¬ ted at N, then at O, and afterwards at P, will form a fecond reprefentation of the fame point at Qj And thirdly, another pencil, whofe axis is ER, after reflec¬ tion at the feveral points R, S, H, T, V, fuccefiively, will exhibit a third reprefentation of the fame point at X ; and fo on in infinitum. The fame being true of each point in the object, the whole will be reprefented in the like manner; but the reprefentations will be faint, in proportion to the number of reflections the rays fuffer, and the length of their progrefs within the glafs. We may add to thefe another reprefentation of the fame objedt in the line LO produced, made by fuch .of the rays as fall upon O, and are from thence reflec¬ ted to the eye at L. This experiment may be tried by placing a candle before the glafs as at E, and viewing it obliquely, as fiom L. 2. Of Concave and Convex Mirrors. The effedls of thefe in magnifying and diminilhing objedts have been already in general explained ; but for the better un- derftanding the nature of reflecting telefcopes, it will ft ill be proper to fubjoin the following particular de- fcription of the effedts of concave ones. ' rvuii When parallel rays, (fig. 2.) as dfat C?nb, etc, ’ ’ fall upon a concave mirror AB (which is not tranfpa- rent, but has only the furface Abb oi a clear polifli) they will be refiedted back from that mirror, and meet in a point m, at half the diflanceof the furface of the mirror from C the centre of its concavity; for they will be reflected at as great an angle from a perpen¬ dicular to the furface of the mirror, as they fell upon it with regard to that perpendicular, but on the other fide thereof. Thus, let C be the centre of concavity of the mirror A ^B; and let the parallel rays dfat G mb, and elc, fall upon it at the points a, b, and c. Draw the lines Cia, Cmb, and Cbc, from the cen¬ tre C to thefe points; and all thefe lines will be per¬ pendicular to the furface of the mirror, becaufe they proceed thereto like fo many radii or fpokes from its centre. Make the angle Cab equal to the angle da C, and draw the line amh, which will be the direc¬ tion of the ray dfa, after it is reflected from the point a of the mirror: fo that the angle of incidence daC, is equal to the angle of reflection Cab; the rays making equal angles with the perpendicular C on its oppofite Tides. Draw alfo the perpendicular to the point c, where the ray elc touches the mirror; and having made the angle 2c i equal to the angle Ctf?, draw the I C S. Part in. line cmi, which will be the courfe of the ray elc, af- Of Optical | ter it is reflected from the mirror. Iifttramems The ray G mb paffing thro’ the centre of concavity of the mirror, and falling upon it at b, is perpendicu¬ lar to it; and is therefore reflected back from it in the fame line bmC. j All thefe reflected rays meet in the point m; and in that point the image of the body which emits the pa¬ rallel rays da, Cb, and and an eye-glafs ef The CCX. fmall objed ab is placed at a little greater diftance from the glafs c d than its principal focus; fo that the pencils of rays flowing from the different points of the objed, and pafling through the glafs, may be made to converge, and unite in as many points between g and hy where the image of the objed will be formed: which image is viewed by the eye through the eye- glafs ef. For the eye-glafs being fo placed, that the image g h may be in its focus, and the eye much about the fame diftance on the other fide, the rays of each pencil will be parallel after going out of the eye- glafs, as at e and f, till they come to the eye at h, where they will begin to converge by the refradive power of the humours; and after having croffed each other in the pupil, and paffed through the cryftalline and vitreous humours, they will be colleded into points on the retina, and form the large inverted image AB thereon. i(f2 By this combination of lenfes, the aberration ofufeof fe* the light from the figure of the glafs, which in a glo- yeral lenfes bule of the kind abovementioned is very confiderable,in a <\om: is in fome meafure correded. This appeared fo fen-crofcop?.1* fibly to be the cafe, even to former opticians, that they very foon began to make the addition of another lens. The inftrument, however, receives a confiderable improvement by the addition of a third lens. For, fays Mr Martin, it is not only evident from the theory of this aberration, that the image of any point is ren¬ dered lefs confufed by refraction through two lenfes, 31 N 2 than 5578 OPT Of Optical than by an equal refraftion through one; but it alfo 3;Utrunients£0]j0VVE} fr0m the fame principle, that the fame point has its image ftill lefs confufed when formed by rays re- frafted through three lenfes, than by an equal refrac¬ tion through two; and therefore a third lens added to the other two, will contribute to make the image more diftin<5t, and confequently the inftrument more com¬ plete. At the fame time the field of view is ampli¬ fied, and the ufe of the microfcope rendered more agreeable, by the addition of the other lens. Thus alfo we may allow a fomewhat larger aperture to the objeft-lens, and thereby increafe the brightnefs of objects, and greatly heighten the pleafure of viewing them. For the fame reafon, Mr Martin has propofed a four-glafs microfcope, which anfwers the purpofes of of magnifying and of dillindt vificn ftill more per- feftly. The magnifying power of double microfcopes is ea- Plate fily underftood, thus: The glafs L next the objedt PQ^ CCXVin. veryfmall, and very much convex, and confequently 7‘ its focal diftance LF is very ftiort; the diftance LQjaf the fmall objedt PQ^is but a little greater than LF: fo that the image /> q may be formed at a great di¬ ftance from the glafs, and confequently may be much greater than the objedl itfelf. This pidhire pq being viewed through a convex glafs AE, whofe focal di¬ ftance is q E, appears diftindt as in a telefcope. Now the objedf appears magnified upon two ac¬ counts ; firft, becaufe, if we viewed its pidfure pq with the naked eye, it would appear as much greater than the objedf, at the fame diftance, as it really is greater than the objedt, or as much as L y is greater than LQ^ and, fecondly, becaufe this pic¬ ture appears magnified through the eye-glafs as much as the leaft diftance at which it can be feen diftindlly with the naked eye, is greater than yEj.the focal diftance of the eye-glafs. For example, if this latter ratio be five to one, and the former ratio of L y to LQJ^e 20 to i; then, upon both accounts, the objedt will appear 5 times 20, or 100 times greater than to the naked eye. Fig. 2. reprefents a compound microfcope with three lenfes. By the middle one GK the pencils of rays coming from the objedt-glafs are refradted fo as to tend to a focus at O; but being intercepted by the proper eye-glafs DF, they are brought together at I, which is nearer to that lens than its proper focus atL; fo that the angle DIF, under which the objedl now appears, is larger than DLF, under which it would have appeared without this additional glafs; and con¬ fequently the objedt is more magnified in the fame proportion. Dr Hooke tells us, that, in moft of his obfervations, he made ufe of a double microfcope with this broad middle-glafs when he wanted to fee much of an objedt at one view, and taking it out when he would examine the fmall parts of an objedt more ac¬ curately; for the fewer refradtions there are, the more jjj. bright and clear the objedt appears. How to In microfcopical lenfes whofe focal diftances are not preferve the much (horter than half an inch, there is no need to contradt their apertures for procuring diftindt vifion; in diffe- * t^ie PUP^ itfelf being fmall enough to exclude the ex¬ rent magni- terior ftraggling rays. But in fmaller lenfes, where fers. apertures are neceflary, Dr Smith has demonftrated, that, to preferve the fame degree of diftindtnefs, their I c s. Part III. apertures muft be as their focal diftances, and then Of Optical the apparent brightnefs will decreafe in a duplicate In^rument ratio of their focal diftances: fo that, by ufing fmaller glaffes, the apparent magnitude and the obfcurity of the objedl will both increafe in the fame ratio. F the ratio of PD to PF being invariable, the angle Fig. 3. PFD is alfo invariable; and confequently the quan¬ tity of light received from the point F is alfo invari¬ able ; becaufe the apertures of the lenfes, whether fmaller or larger, mnft all be fituated at fuch diftances from F as juft to receive all the rays contained in a tone defcribed by^turning the angle PFD about the axis PF, neither more nor lefs. But the apparent magnitude of the objedl, or the furface of its pidhire upon the retina, is reciprocally as PF fquare; and confequently, the light being the fame, its brightnefs is dfredlly as PF fquare. By this theory it appears, that a minute objedt cannot be magnified to infinity by a fingle lens, though it were poffible to make it as fmall as we pleafe, without fome method of increafing its light. Neverthelefs, this imperfedtion in fingle microfcopes is not fo great as at firft fight one would take it to be, or as in fadt we find it; the reafon may be, becaufe the eye is capable of discerning objedts tolerably well by above 20,000 different degrees of light. But though the brightnefs of the objedt were increafed by throwing new light upon it, yet Huygens pbferves, that the power of the microfcope will ftill be limited by the breadth of the pencils which enter the pupil; which is equal to the breadth of the aperture. For, if this breadth be lefs than or £ of a line, he affirms that the edges of the objedl will begin to appear indiftindt. But by double mi¬ crofcopes this author has made it appear, that we may magnify objedls at pleafure, provided it was poffible to form their objedt-glaffes fufficiently fmall. 3. The Solar Microfcope (fig. 4..), invented by Drpiatc Lieberkuhn, is conftrudted in the following manner. CCXVII. Having procured ,a very dark room, let a round hole be made in the windovv-ffiutter, about three inches diameter, through which the fun may caft a cylinder of rays AA into the room. In this hole place the end of a tube containing two convex glaffes and an objedt, viz. 1. A convex glafs a a, of about two inches diameter, and three inches focal diftance, is to be placed in that end of the tube which is put into the hole. 2. The objedt bb being put between two glaf¬ fes, which muft be concave to hold it at liberty, is placed about two inches and a half from the glafs a a. 3. A little more than a quarter of an inch from the objedt is placed the fmall convex glafs cc, whofe focal diftance is a quarter of an inch. The tube may be fo ‘‘placed when the fun is low, that his rays AA may enter diredtly into it; but when he is high, his rays BB muft be refledted into it by the mirror CC. Things being thus prepared, the rays that enter the tube will be con¬ veyed by the glafs a a towards the objedt bb^ by which means it will be ftrongly illuminated, and the rays d, which flow from it through the convex lens cc, will make a large inverted pidture of the objedt at DD, which, being received on a white paper, will reprefent- the objedt magnified in length, in the proportion of the diftance of the pidture from the glafs c c to the di¬ ftance of the objedt from the fame glafs.

We may fuppofe this glafs GH to be from three to fix inches diameter; and therefore, in our example, let it be a lens of 4 inches diameter, and its focal diftance 12 inches. Then the looking-glafs EF being properly adjufted, and the lens GH fo pofited as to receive the rays of the fun a, 6, c, in a perpendicular diredlion, they will be refradted through it, tending towards a focus in the axis IL at 12 inches from the lens. But this cone of rays falling upon the glafs EF, between K and L, will, by it, be refledied to a focus O in the refledted axis L,g, which is parallel to the horizon. Now the focus O of any lens being the image of the fun, will of courfe be a circle; and in the prefent cafe of a lens 12 inches focal diftance, this circle will be extremely near tV of an inch diameter, by allowing 3o'-«for the diameter of the fun. Hence the vertex N of the cone will be of an inch beyond the focus O. Therefore the diameter of the fedLon of the cone within the focus, will be of an inch ; at ^ within the focus, the fedlion will be ; at from the fo-. cus, the fedlion will be -rcr > an(f at J-iV from the focus, the fediion will be or half an inch in dia¬ meter. Therefore at of an inch from the focus the fec- tion of the cone will be alfo of an inch in diameter; and it is found by experience that nearer the focuS O no objedts can be placed. Therefore the firft inch and quarter of the radious cone may be applied for all the various powers of magnifying microfcopic objedis; and from thence, through the next inch, the me- galafcope may be applied in the greateft perfediion. Let Z be the centre of the hole CD in the frame, then ZO will be about yi of the 12 inches, and confequently long enough for a movement of the mi- crofcope and megalafcope through the 2 inches juft mentioned. Hence it will appear, that in this con- ftrudlion of the folar microfcope* a much lefs appara¬ tus of tube-work will be neceffary than in the common fort, where DOC makes all the cone, and the length Z^ is 7 or 8 inches. If we put the diameter of the common illuminator CD=i,5, and the diameter of the lens GH=3, then, in the fame fedlion RS of the cone produced by each lens feparately, we have the intenfity of light as CD* to GH% that is, as 2,25 to 9, or as 1 to 4. If GH=4, then the ratio of the increafe of light will be that of 2,25 to 16, or as 1 to 7,1. Suppofe 1 C S. 5579 GH = 5 ; then 2, 25 : 25 : : t : 11 nearly. So that Of Optical by this conftrudlion you may increafe the light uponJn^run~‘ei>ts objedfs, or their images, at leaft feven times with eafe, or ten times with very little trouble or expence. § 4. Teltfcopes. I. The Refracting Telescope. After what has been faid concerning the ftrudlure of the compound microfcope, and the manner in wlfich the rays pafs through it to the eye, the nature of the common aftronomical telefcope will eafily be under- ftood : for it differs from the microfcope only in that the objedl is placed at fo great a diftance from it, that the rays of the fame pencil, flowing from thence, may be confidered as falling parallel to one another upon the objedl-glafs; and therefore the image made by that glafs is looked upon as coincident with its focus of parallel rays. 1. The 6th figure will render this very plain ; in Plate which AB is the objedl emitting the feveral pencilsCCXVlL of rays A.dc, Red, &c. but fuppofed to be at fo great a diftance from the objedl-glafs e d, that the rays of the fame pencil may be confidered as parallel to each other; they are therefore fuppofed to be cclledted into their refpedtive foci at the point m and />, fituated at the focal diftance of the objedl-glafs c d. Here they form an image E, and croffing each other proceed diverging to the eye-glafs ^ ; which being placed at its own focal diftance from the points m and />, the rays of each pencil, after pafiing through that glafs, will become parallel among themfelves; but the pencils themfelves will converge confiderably with refpedl to one another, even fo as tocrofs at e, very little farther from the glafs gh than its focus ; becaufe, when they entered the glafs, their axes were almoft parallel, as coming through the objedl-glafs at the point k, to vvhofe diftance the breadth of the eye-glafs in a long telefcope bears very fmall proportion. So that the place of the eye will be nearly at the focal diftance of the eye-glafs, and the rays of each refpedlive pencil being parallel^among themfelves, and their axes crofting each other in a larger angle than they would do if the objedl were to be feen by the naked eye, vifion will be diftindl, and the objedl will appear magnified. The power of magifying in this telefcope is as the focal length of the objedl-glafs to the focal length of the eye-glafs. Dem. In order to prove this, we may confider the angle A^B as that under which the objedl would be feen by the naked eye; for in confidering the diftance of the objedl, the length of the telefcope may be omit¬ ted, as bearing no proportion to it. Now' the angle under which the objedl is feen by means of the tele¬ fcope, \§ geh, which is to the other AIB, or its equal gklu as the diftance from the centre of the objedl-glafs to that of the eye-glafs. The angle, therefore, under which an objedl appears to an eye aflifted by a tele- fcopc of this kind, is to that under which it vvguld be feen without it, as the focal length of the objedl-glafs to the focal length of the eye-glafs. It is evident from the figure,, that the vifible area, or fpace which can be feen at one view when we look through this telefcope, depends on the breadth of the eye-glafs, and not of the objedl-glafs; for if the eye- glafs be too fmall to receive the rays^;«, fb7 the ex¬ tremities 558° Of Optical Inftrument! Plate CCXVII. Plate1 CCXVII. OPT tremities of theobjeft could not have been feen at a!!: 1 a larger breadth of the objetft-glafs conduces only to the rendering eacli point of the image more luminous by receiving a larger pencil of rays from each point of the objeft. It is in this telefcope as in the compound micro- fcope, where we fee, when we look through it, not the objeft itfelf, but only an image of it at CED: now that image being inverted with refpefit to the objedl, as it is, becaufe the axes of the pencils that flow from the objedf erofs each other at k, obje&s feen through a telefcope of this kind neceflarily appear inverted. This is a circumftance not at all regarded by aftro- nomers : but for viewing obje&s upon the earth, it is convenient that the telefcope rtiould reprefent them in their natural pofture; to which ufe the telefcope with three eye-glaffes, as reprefented fig. 7. is peculiarly adapted, and the progrefs of the rays through it from the objedl to the eye is as follows: AB is the objeft fending out the feveral pencils Acd, Red, &c. which paffing through the objecl- glafscaf, are eollefted into their refpeftive foci in CD, where they form an inverted image. From hence they proceed to the firft eye-glafs ef, whofe focus being at /, the rays of each pencil are rendered parallel among tbemfelves, and their axes, which were nearly parallel before, are made to converge and crofs each other: the fecond eye-glafs gbt being fo placed that its focus ftiall fall upon m, renders the axis of the pencils which diverge from thence parallel, and caufes the rays of each which were parallel among themfelves to meet again at its focus EF on the other fide, where they form a fecond image inverted with refpeft to the for¬ mer, but ereft with refpefl: to the objeft. Now this image being feen by the eye at ab through the eye- glafs iky affords a direft reprefentation of the objedl, and under the fame angle that the firft image CD wbuld have appeared, had the eye been placed at /, fuppofing the eye-glaffes to be of equal convexity ; and therefore the objedt is feen equally magnified in this as in the former telefcope, that is, as the focal di¬ fiance of the objedl- glafs to that of any one of the eye- glafles, and appears eredt. If a telefcope exceeds 20 feet, it is of no ufe in view¬ ing objedts upon the furface of the earth; for if it mag¬ nifies above 90 or too times, as thofe of that length ufually do, the vapours, which continually float near the earth in great plenty, will be fo magnified as to render vifiou obfeure. 2. The Galilean Telefcope with the concave eye-glafs is conftrudled as follows: AB (fig. 5.) is an objedl fending forth the pencils of vzys g h i, k lin, &c. which, after pafiing through the object-glafs cdy tend towards eE_/'(where we will fnppofe the focus of it to be), in order to form an in¬ verted image there as before; but in their way to it arc made to pafs through the concave glafs no, fo pla- I C S. Parti] ced that its focus may fall upon E, and jconfequently Of Opd the rays of the feveral pencils which were convergingInftrum* towards thofe refpedtive focal points e, E,y^ will be” rendered parallel among themfelves ; but the axes of thofe pencils croffing each other at F, and diverging from thence, will be rendered more diverging, as re¬ prefented in the figure. Now thefe rays entering the pupil of an eye, will form a large and diftindl image ab upon the retina, which will be inverted with refpedt to the objedl, becaufe the axes of the pencils crofs in F; and the angle the objedl will appear under will be equal to that which the lines a¥, b¥, produced back through the eye-glafs, form at F. It is evident, that the lefs the pupil of the eye is, the lefs is the vifible area feen through a telefcope of this kind; for a lefs pupil would exclude fuch pencils as proceed from the extremities of the objedl AB, as is evident from the figure. This is an inconvenience that renders this telefcope unfit for many ufes; and is only to be remedied by the telefcope with the convex eye-glaffes, where the rays which form the extreme parts of the image are brought together in order to enter the pupil of the eye, as explained above. It is apparent alfo, that the nearer the eye is placed to the eye-glafs of this telefcope, the larger is the area feen through it; for, being placed dole to the glafs, as in the figure, it admits rays that come from A and B, the extremities of the objedl, which it could not if ' it was placed farther off. The degree of magnifying in this telefcope is in the fame proportiort with that in the other, wz. as the fo¬ cal diftance of the objedt-glafs is to the focal-diftancc of the eye-glafs. For there is no other difference but this, viz. that as the extreme pencils in that telefcope were made to converge and form the angle (fig. 6.), ox i n k (fig. 7.), thefe are now made to diverge and form the angle «F£ (fig. 5.) ; which angles, if the concave glafs in one has an equal refradlive power with the convex one in the other, will be equal, and therefore each kind will exhibit the objedl magnified in the fame de¬ gree. There is a defedt in all thefe kinds of telefcopes, not to be remedied in a fingle lens by any means whatever, which was‘thought only to arife from hence, viz. that fpherical glaffes do not colledl rays to one and the fame point. But it was happily dif- covered by Sir Ifaac Newton, that the imperfec¬ tion of this fort of telefcope, fo far as it arifes from the fpherical form of the glaffes, bears almoft no pro¬ portion to that which is owing to the different re- frangibility of light. This diverfity in the refradlion of rays is about a 28th part of the whole; fo that the objedi-glafs of a telefcope cannot colledl the rays which impjrfe,.. flow from any one point in the objedl into a lefs room tion in than the circularfpace whofe diameter is about the56th dioptrical part of the breadth of the glafs (a). Therefore, fince telefcoPes* each (A) To fhew this, let AS, fig. 1. reprefent a convex lens, and let CDF be a pencil of rays flowing from the point D : let H be the pmnt at which the leaft refrangible rays are colkdted to a focus; and I, that where the moft refrangible concur. Then, if IH be the 28th part of EH, IK will be a proportionable part of EC (the triangles iIK and HEC being fimilar): confequently LK will be the 28th part of FC. But MN will be the leaft fpace in- to vyhich the rays will be collected, as appears by their progrefs reprefented in the figure. Now MN is but about halt of KL; and therefore it is about the j6th part of CF: fo that the diameter of the fpace, into which the rays are colledled, will be about the 56th part of the breadth of that part of the glafs thro’ which the rays pals. Which was to be fhewn. r o 1 v Part III. OPT Of Optical each point of the obje& will he reprefented ia fo large ffftruincntsa fpace, and the centres of thofe fpaces will be conti¬ guous, becaufe the points in the obje& the rays flow from are fo; it is evident, that the image of an objedt made by fuch a glafs mull be a mod confufed repre- fentation, though it does not appear fo when viewed through an eye-glafs that magnifies in a moderate de¬ gree ; confequently the degree of magnifying in the eye-glafs mull not be too great with refpeft to that of the object-glafs, left the confufion become fen- fible. Notwithftanding this imperfe&ion, a dioptrical te- lefcope may be made to magnify in any given degree, provided it be of fufficient length ; for the greater the focal diftance of the objedt-glafs is, the kfs may be the proportion which the focal diftance of the eye-glafs may bear to that of the objedl-glafs, without render¬ ing the image obfcure. Thus, an objeft-glafs, whofe focal diftance is about four feet, will admit of an eye- glafs whofe focal diftance fhall be liitle more than an inch, and confequently will magnify almoft 48 times : but an objedt-glafs of 40 foot focus will admit of an eye-glafs of only four-inch focus, and will therefore magnify 120 times; and an objedt-glafs of too foot focus will admit of an eye-glafs of little more than fix-inch focus, and will therefore magnify almoft zoo times. The reafon of this difproportion in their feveral de¬ grees of magnifying is to be explained in the follow¬ ing manner. Since the diameter of the fpaces, into which rays flowing from the feveral points of an ob- jedl are colledted, are as the breadth of the objedl- glafs, it is evident that the degree of confufednefs in the image is as the breadth of that glafs; for the de¬ gree of confufednefs will only be as the diameters or breadths of thofe fpaces, and not as the fpaces them- felves. Now the focal length of the eye-glafs, that is, its power of magnifying, muft be as that degree ; for, if it exceeds it, it will render the confufednefs fen- Able; and therefore it muft be as the breadth or dia¬ meter of the objedt-glafs. The diameter of the ob- j eA-glafs, which is as the fquare root of its aperture or magnitude, muft be as the fquare-root of the power of magnifying in the telefcope ; for unlefs the aper¬ ture itfelf be as the power of magnifying, the image will want light: the fquare root of the power of magnifying will be as the fquare root of the focal diftance of the objeft-glafs ; and therefore the fo¬ cal diftance of the eye-glafs muft be only aS the fquare root of that of the objeft-glafs. So that in making ufe of an objedl-glai's of a longer focus, fuppofe, than one that is given, you are not obli¬ ged to apply an eye-glafs of a proportionably longer focus than what would fuit the given objecl-glafs, but fuch an one only whofe focal diftance (hall be to the fo¬ cal diftance of that which will fuit the given objedl- glafs, as the fquare root of the focal length of the ob¬ jedt-glafs you make ufe of, is to the fquare root of the focal length of the given one. And this is the reafdn that longer telefcopes are capable of magnify¬ ing in a greater degree than fhorterones, without ren- x66 dering the objedt ponfufed or coloured. How reme- 3. Doilond's ‘Telefcopes.—The general principle on died by Mr^jch tj,;g artift’s celebrated improvement of therefrac- 0 ou ' ting telefcope depends, hath been already mentioned } ICS. - 5iSi namely, that by the different powers of refradlion in two Of Optical kinds of glafs, and by their different powers of difner- Ir'ftrumei1ts fing the rays, theerrofs arifing from the different refran- gibility of the light are in a great meafute, if nottotallyj corredted.—For this purpofe the objedl-glaffes of his telefcopes are compofed of three diftindl lenfes, ria'c two convex and one concave; of which the concave^cxvr’ one is placed in the middle, as is reprefenled in fig. 6. where a and e (hew the two convex lenfes, and 60 the concave one, which is by the Britifh artifts placed in the middle. The two convex ones are made of green glafs, and the middle one of white flint glafs, and are all ground to fpheres of the fame radius. When put together, they refradl the rays in the following manner. Let ab, db, be two red rays of the fun’s light falling '• parallel on the firft green convex lens c. Suppofing there was no other lens prefent but that one, they would then be converged into the lines be, be, and at laft meet in the focus q. Let the lines gh, g b, re- prefent two violet rays falling on the furface of the lens. Thefe are alfo refradted, and will meet in a focus; but as they have a greater degree of refran- gibiiity than the red rays, they trinft, of confe- quence, converge more by the fame power of refrac¬ tion in the glafs, and meet fooner in a focus, fuppofe at r.—Let now the concave lens d d be placed in fuch a manner as to intercept all the rays before they come to their focus. As this lens is ground to the fame radius with the convex one, it muft; have the fame power to caufe the rays diverge that the former had to make them converge ; that is, fuppofing them both to be made of the fame materials. In this cafe, the red rays would become parallel, and move on in the line 00, ope But the concave lens, being made of white glafi, has a greater refradlive power, and therefore they diverge a little after they come out of it ; and if no third lens was interpofed, they would proceed diverging in the lines opt, opt; but, by the interpofition of the third lens ovo, they are again made to converge, and meet, in a focus fomewhat more diftant than the former, as at x. By the concave lens the violet rays are alfo refradled, and made to diverge : but having a greater degree of refrangibility, the fame power of refradion makes them diverge fomewhat more than the red ones;, and thus, if no third lens was interpofed, they would proceed in fuch lines as hnn, linn. Now as the differently coloured rays fall upon the third lens with different degrees of divergence, it is plain, that the fame power of refradion in that lens will operate upon them in fuch a manner as to bring them all together to a focus very nearly at the fame point. The red rays, it is true, require the greateft power of refrac¬ tion to bring them to a focus ; but they fall upon the lens with the lead degree of divergence. The violet rays, though they require the lead power of refradion, yet have the greateft; degree of divergence; and thus all meet together at the point x, or very nearly fo. But, though we have hitherto fuppofed the refrac¬ tion of the concave lens to be greater than that of the convex ones, it is eafy to fee how the errors occafion- ed by the firft lens may be correded by it, though it ftiould ha've even a lefs power of refradion than the convex one. Thus, let ab, ab, fig* 8. be two rays of red light falling upon the convex lens c, and refraded into the focus q; let alfog^, gb} be two violet rays can* 55B2 OPT Of Optical converged into a focus at r; itis not neceflary, in order Inftrements jq the,',- convergence into a common focus at x, that the ~~ concave lens (hould make them diverge: it isfufficient if the glafs has a power of difperfing the violet rays fomewhat more than the red ones ; and many kinds of glafs have this power of difperfing fome kinds of rays, without a very great power of refraction. It is better, however, to have the objedt-glafs compofed of three lenfes; becaufe there is then another correction of the aberration by means of the third lens; and it might be impofiible to find two lenfes, the errors of which would exaCtly correCt each other. It is alfo eafy to fee, that the effeCt may be the fame whether the con¬ cave glafs is a portion of the fame fphere with the others or not; the effeCt depending upon a combina¬ tion of certain circumllances, of which there is an in¬ finite variety. By means of this correction of the errors arifing from the different refrangibility of the rays of light, it is poffible to fhorten dioptric telefcopes confider- ably, and yet leave them equal magnifying powers. The reafon of this is, that the errors arifing from the objeCt-glafs being removed, thofe which are occafion- ed by the eye-glafs are inconfiderable: for the error is always in proportion to the length of the focus in any glafs ; and in very long telefcopes it becomes ex¬ ceedingly great, being no lefs than of the whole ; but in glaffes of a few inches focus it becomes trifling. RefraCting telefcopes which go by the name of Dol- plste land’s, are therefore now. conftruCted in the following CCXVIII. manner. Let AB (fig. I.) reprefent an objeCt-glafs compofed of three lenfes as above defcribed, and con- verging the rays I, 2, 3, 4, &c. to a very diftant focus as at x. By means of the interpofed lens CD, however, they are converged to one much nearer, as at^>, where an image of the objeCt is formed. The rays diverging from thence fall upon another lens EF, where the pencils are rendered parallel, and an eye placed near that lens would fee the objeCt magnified and very diftinCt. To enlarge the magnifying power ftill more, however, the pencils thus become parallel are made to fall upon another at GH; by which they are again made to converge to a diilant focus: but, being intercepted by the lens IK, they are made to tneet at the nearer one z; whence diverging to LM, they are again rendered parallel, and the eye at N fees the objeCt very diftinCtly. From an infpeCtion of the figure it is evident, that Dollond’s telefcopc thus conitruCted is in fad two te- lefcopes combined together; the firft ending with the lens EF, and the fecond with LM. In the firft we do not perceive the objeft itfelf, but tlie image of it formed at ; and in the fecond we perceive only the image of that image formed at z. Neverthelefs fuch telefcopes are exceedingly diftinCt, and reprefent ob¬ jects fo clearly as to be preferred, in viewing terreftrial things, even to refleCtprs themfelves. The latterindeed have greatly the advantage in their powers of magni¬ fying, but they are much deficient in point of light. Much more light is loft by refieCtion than by refrac¬ tion : and as in thefe telefcopes-the light muft una¬ voidably fuffer two reflections, a great deal of it is loft; nor is this lofs counterbalanced by the great¬ er aperture which thefe telefcopes will bear, which enables them to receive a greater quantity of light I C S. Part Illi than the refraCIing ones. The metals of reflefting tele- Of Optica fcopes alfo are verymuch fubjeftrto tarnifh, and requireIn^ru 11161 much more dexterity to clean them than the glaffes of refraCtors; which makes them more troublefome and expenfive, though for making difeoveries in the cele- ftial regions they are undoubtedly the only proper in- ftruments. II. The Reflecting Telescope. 1. Of Sir Ifaac Newton's Refletting Telefcope. The inconveniences arifing from the great length of refrac¬ ting telefcopes are fufficiently obvious; and thefe, to¬ gether with the difficulties arifing from the different refrangibility of light, induced Sir Ifaac Newton to give attention to the fubjeCt of reflection, and endea¬ vour to realize the ideas of himfelf and others con¬ cerning the poffibility of conftruCting telefcopes upon p]ate l this principle. The inftrument he contrived is repre- CCXVI. > fented fig. 9. where ABCD is the tube, BC a con¬ cave reflecting metal, EF a plain reflecting metal fix¬ ed to the tube by means of the ftem HI. MN repre- fents a diftant objeCt emitting pencils of rays from each point, two only of which are here reprefented, and thofe cut off before they reach the metal, to prevent confufion in the figure. Now it is evident from what has been explained above, that thefe rays, were they not intercepted in their way, would return after reflec¬ tion at the concave furface BC, and form an inverted image at OP, fuppofing that to be the place of the focus of reflected rays. But in this cafe the reflected rays are intercepted in their return to that place by the plain metal, and are thereby thrown fidewife; and in- ftead of forming the image OP, are made to form the image QR : which, becaufe the rays have as yet fuf- fered no refraCtion, is not liable to the imperfeCtion which arifes from the different refrangibility of the rays of light, nor to any other except what may arife from an imperfeCt polifh, or the want of the form of one of the conic feCtions in the refleCtor BC; and therefore may be viewed by an eye at T with a very fmall lens or eye-glafs KL, without appearing either coloured or confufed. 2. The Gregorian telefcope. This remedies the in¬ convenience of the Newtonian one, by which ob¬ jects are found with difficulty. This defeCt, indeed, was in forne meafure removed by having a fmall refrac¬ ting telefcope with two hairs, or wires, running thro’ the tube in the common focus of the two glaffes, and croffing each other at right angles; and the objeCt be¬ ing firft viewed through this fmall telefcope was after¬ wards eafily found by the refleCtor. But the inconve¬ nience is more effectually remedied by the following conftruCtion. pjate At the bottom of the great tube TTTT (fig. 8.)cCXVM. is placed the large concave mirror DUVF, whole prin¬ cipal focus is at m; and in its middle is a round hole P, oppofite to which is placed the fmall mirror L, concave toward the great one; and fo fixed to a ftrong wire M, that it may be moved farther from the great mirror, or nearer to it, by means of a long ferew on the outfide of the tube, keeping its axis lull in the fame line Rmn with that of the great one. Now, fince in viewing a very remote objeCt, we can fcarce fee a point of it but what is at leaft as broad as the great mirror, we may confider the rays of each pencil, which flow Part III. OPT Optical flow from every point of the objeft, to be parallel to Inftrumentseac^ other, and to cover the whole reflefting furface DUVF. But to avoid confufion in the figure, we fliall only draw two rays of a pencil flowing from each ex¬ tremity of the objeft into the great tube, and trace their progtefs, through all their refledtions and refrac¬ tions, to the eye f, at the end of the fmall tube which is joined to the great one. Let us then fuppofe the objedt AB to be at fuch a diftance, that the rays C may flow from its lower ex¬ tremity B, and the rays E from its upper extremity A. Then the rays C falling parallel upon the great mirror at D, will be thence reflected converging^ in the di¬ rection DG; and by crofling at I, in the principal fo¬ cus of the mirror, they will form the upper extremity I of the inverted image IK, fimilar to the lower ex¬ tremity B of the objedt AB: and palling on to the concave mirror L (whofe focus is at ») they will fall upon it at g, and be thence refledted converging, in the direction ^N, becaufep-w is longer than and palling through the hole P in the large mirror, they would meet fomewhere about r, and form the lower extremity D of the eredt image a d, fimilar to the lower extremity B of the objedt AB. But by palling through the plano-convex glafs R in their way, they form that extremity of the image at b. In like man¬ ner, the rays E, which come from the top of the ob- jedl AB, and fall parallel upon the great mirror at F, are thence refledted converging to its focus, where they form the lower extremity K of the inverted image IK, fimilar to the upper extremity A of the objedt AB ; and thence palling on to the fmall mirror L, and fall- ing upon it at they are thence refledted in the con- verging Hate hO-, and going on through the hole P of the great mirror, they would meet fomewhere about q, and form there the upper extremity a of the eredl image ad, fimilar to the upper extremity A of the ob¬ jedt AB: but by palling through the convex glafs R in their way, they meet and crofs fooner, as at a, where the point of the eredt image is formed. The like be¬ ing underftood of all thofe rays which flow from the intermediate points of the objedt between A and B, and enter the tube TT, all the intermediate points of the image between a and b will be formed ; and the rays palling on from the image, through the eye-glafs S, and through a fmall hole e in the end of the lef- fer tube tt, they enter the eye f, (which fees the image by means of the eye-glafs) under the large angle ced, and magnified in length under that angle from c to d. In the bell reflediing telefcopes, the focus of the fmall mirror is never coincident with the focus ?n of the great one, where the firft image IK is formed, but a little beyond it (with refpedl to the eye), as at n: the confequence of which is, that the rays of the pencils will not be parallel after refledlion from the fmall mirror, but converge fo as to meet in points about q,e,r\ where they would form a larger upright image than a b, if the glafs R was not in their way ; and this image might be viewed by means of a Angle eye-glafs properly placed between the image and the eye: but then the field of view would be lefs, and corifequently not fo pleafant; for which reafon, the glafs R is ftill retained, to enlarge the fcope or area of the field.

VIII. 2 ICS.’ J583 To find the magnifying power of this telefcope, < >;»tical multiply the focal diftance of the great mirror by theInftri,mei,t5 diftance of the fmall mirror from the image next the eye, and multiply the focal diftance of the fmall mir¬ ror by the focal diftance of the eye-glafs; then divide the produdf of the former multiplication by the pro- dudf of the latter, and the quotient will exprefs the magnifying power. One great advantage of the refle&ing telefcope is, that it will admit of an eye-glafs of a much ftiorier focal diftance than a refradling telefcope wHl ; and, confequently, it will magnify fo much the more : for the rays are not coloured by refle&ion from a concave mirror, if it be ground to a true figure, as they arc by palling through a convex-glafs, let it be ground ever fo true. The adjufting ferew on the outfideof the great tube fits this telefcope to all forts of eyes, by bringing the fmall mirror either nearer to the eye, or removing it farther; by which means the rays are made to diverge a little for ftiort-fighted eyes, or to converge for thofe of a long fight. The nearer an objefl is to the telefcope, the more its pencils of rays will diverge before they fall upon the great mirror, and therefore they will be the longer of meeting in points after reflexion ; fo that the firft; image IK will be formed at a greater diftance from the large mirror, when the objeft is near the tele¬ fcope, than when it is very remote. But as this image muft be formed farther from the fmall mirror than its principal focus n, this mirror muft be always fet at a greater diftance from the large one, in view¬ ing near objefts, than in viewing remote ones. And this is done by turning the ferew on the outfide of the tube, until the fmall mirror be fo adjufted, that the objeft (or rather its image) appears perfeft. In looking through any telefcope towards an ob- je£l, we never fee the objeft itfelf, but only that image of it which is formed next the eye in the tele¬ fcope. For if a man holds his finger or a ftick be¬ tween his bare eye and an objed, it will hide part (if not the whole) of the objeft from his view. But if he ties a ftick acrofs the mouth of a telefcope be¬ fore the ohjedt-glafs, it will hide no part of the ima¬ ginary objedt he faw through the telefcope before, unlefs it covers the whole mouth of the tube; for all the effedt will be, to make the objedl appear dimmer, becaufe it intercepts part of the rays. Whereas, if he puts only a piece of wire acrofs the infide of the tube, between the eye-glafs and his eye, it will hide part of the objedt which he thinks he fees: which proves, that he fees not the real objedl, but its image. This is alfo confirmed by means of the fmall mirror L, in the refledting telefcope, which is made of opake metal, and ftands diredtly between the eye and the objedt towards which the telefcope is turned ; and will hide the whole objedt from the eye at e>, if the two glafles R and S are taken out of the tube. § 5. Camera Obfcura. The camera obfcura is made by a convex-glafs CD (fig. 2.) placed in a hole of a window-fhutter. pfate Then if the room be darkened, fo as no light can en-CCXVI. ter but what comes thro’ the glafs, the pidtures of all the objedts (as fields, trees, buildings, men, 31 O cattle. i5§4 OPT Optical cattle, &c.) on the outfide, will be (hewn in an in- lnftriunentsvertej or(jer} on a white paper placed at GH in the focus of the glafs ; and will afford a mod beautiful and perfect piece of perfpedtive or landfcape of what¬ ever is before the glafs, efpecially if the fun fliines up¬ on the objects. If the convex-glafs CD be placed in a tube in the fide of a fquare box, within which is the plane mirror Plate EF, reclining backwards in an angle of 45 degrees CCXVI. from the perpendicular k q, the pencils of rays flow- ** ing from the outward obje&s, and paffing thro’ the convex glafs to the plane mirror, will be refle&ed up¬ wards from it, and meet in points, as I and K (at the fame diftance that they would have met at H and G, if the mirror had not been in the way,) and will form the aforefaid images on an oiled paper ftretched ho¬ rizontally in the diredlion IK: on which paper the outlines of the images may be eatily drawn with a black-lead pencil ; and then copied on a clean (heet, and coloured by art, as the objefts themfelves are by nature.—In this machine, it is ufual to place a plane glafs, unpolilhed, in the horizontal fituation IK, which glafs receives the images of the outward obje&s ; and their outlines may be traced upon it by a black-lead pencil. N. B. The tube in which the convex-glafs CD is fixed, mull be made to draw out, or pulh in, fo as to adjuft the diftance of that glafs from the plane mirror, in proportion to the diftance of the out¬ ward obje&s; which the operator does, until he fees their images diftinftly painted on the horizontal glafs at IK. The forming a horizontal image, as IK, of an up¬ right objeft AB, depends upon the angles of inci¬ dence of the rays upon the plane mirror EF, being equal to their angles of reflediion from it. For, if a perpendicular be fuppofed to be drawn to the furface of the plane mirror ate, where the ray A.aCe falls upon it, that ray will be refledted upwards in an equal angle with the other fide of the perpendicular, in the line edl. Again, if a perpendicular be drawn to the mirror from the point f, where the ray P^hf falls up¬ on it, that ray will be refledted in an equal angle from the other fide of the perpendicular, in the line fh\. And if a perpendicular be drawn from the point where the ray &.cg falls upon the mirror, that ray will be refledled in an equal angle from the other fide of the perpendicular, in .the line g i I. So that all the rays of the pencil ab c, flowing from the upper extre¬ mity of the objedt AB, and paffing thro’ the convex glafs CD, to the plane mirror EF, will be refledted from the mirror, and meet at I, where they will form the extremity I of the image IK, fimilar to the^xtre- mity A of the objedt AB. The like is to be under- ftood of the pencil qrs, flowing from the lower ex¬ tremity of the objedt AB, and meeting at K (after refledtion from the plane mirror) the rays form the extremity K of the image, fimilar to the extremity B of the objedt: and fo of all the pencils that flow from the intermediate points of the objedt to the mirror, thro’ the convex glafs. If a convex glafs, of a fhort focal diftance, be placed Bear the plane mirror in the end of a ffiort tube, and a sonvex glafs be placed in a hole in the fide of the I C S. Partin. tube, fo as the image may be formed between the Optica! laft-mentioned convex glafs and the plane mirror; theIn^ruments image being viewed thro’ this glafs, will appear mag- “ nified.—In this manner, the Opera-glaffes are con- ftrudted ; with which a gentleman may look at any lady at a diftance in the company, and the lady know nothing of it. § 6. Magic Lantern, ABCD (fig. 5.) is a tin lantern, with a tube nklm fixed in the fide of it. This tube confifts of two joints, one of which flips into the other: and by drawing this joint out, or pufhing it in, the tube may be made longer or fhorter. At k l, in the end of the moveable joint of the tube, a convex lens is fixed ; and an objedt painted with tranfparent colours upon a piece of thin glafs is placed at de, fomewhere in the immoveable joint of the tube ; fo that as the tube is lengthened or fhortened, the lens will be either at a greater or a lefs diftance from this tranfparent objedt. In the fide of the lantern there is a very convex lens bh c, which ferves to caft a very ftrong light from the candle within the lantern upon the objedt ie. Now when the rays, which fhine through the objedt di¬ verge from the feveral points as d, e, Sec. in the ob¬ jedt, and fall upon the lens b /, they will be made to converge to as many points f, g, 8cc. on the other fide of the lens, and will paint an inverted pidture of the objedt at fg upon a white wall, a {heet, or a fereen of white paper, provided the objedt is farther from the lens than its principal focus. To make this pidture appear diftindt and bright, it muft have no other light fall upon it but what comes through the lens and for this reafon the vyhole apparatus is to be placed in a dark room EFGH. The lens k l muft be very con¬ vex, fo that the objedt d e may be very near to it, and yet not be nearer than its principal focus: for by this means, as the objedt is near to the lens, the pidture fg will be at a great diflance from it, and confequent- ly the pidture will be much bigger than the objedt. Since the pidture is inverted in refpedt of the objedt, in order to make the pidture appear with the right end upwards, it is neceffary that the objedt de fhould be placed with the wrong end upwards. Sect. V. A Defcription of the above and other Optical Injlruments, fitted with their Appara¬ tus : with an account of the methods of apply¬ ing them to the purpofes for which they are in¬ tended. § 1. Camera Obfcura and Magic Lantern. See Dioptrics, p. 2477 to p. 2482. $ 2. The Graphical Perfpeflive. This inftrument confifts of two lenfes AB and CD, fig. 1. which are placed at twice their focal diftance piate , from one another; and in their common focus is ano-CCXIX. ther glafs EF, divided into equal parts with the point of a diamond. Though this inftrument does not magnify objedts, yet the angle under which any ob¬ jedt is feen is eafily known by it; and fince this angle varies with the diltance of objedts, it is eafily applied to the purpofe of meafuring inacceffible heights and diftances j. Fart III. OPT Optical diftances ; and fincethe field of view is divided into equal inftrumentsfquaces, k4s ufeful in drawing the perfpedive appear- ” ~ auce of objefts. As all foreign light is excluded by the tube in which thefe lenfes are inclofed, pi&ures feen through this machine have a fine relievo; on which account, as alfo becaufe obje&s appear inverted through it, the images of a camera obfcura are viewed to particular advantage by its means. If a lens of a greater focal length be fixed at a proper didance from the centre of the tube, this inftrument will be a tele- fcope, and will magnify the prints which are looked at through it ; and if a fmall lens be ufed, it will be a microfcope, and the fame micrometer will ferve for both. $ 3. Of the Single Microfcope. The famous microfcopes made ufe of by Mr Leeu¬ wenhoek, were all, as Mr Baker affures us, of the fingle kind, and the condruftion of them the mod finaple poffible, each confiding only of a fingle lens fet between two plates of filver, perforated with a fmall hole, with a moveable pin before it to place the objeft on, and adjud it to the eye of the beholder. He in¬ forms us alfo, that lenfes only, and not globules, were ufed in every one of thefe microfcopes. The fingle microfcope now mod generally known and ufed is that called Wilfon’s Pocket Microfcope. The body is made of brafs, ivory, or filver, and is re- Plate prefented by AA, BB. CC is a long fine-threaded CCXVIII. male-fcrew that turns into the body of the microfcope, 8. D a convex glafs at the end of the fcrew. *, Two con¬ cave round pieces of thin brafs, with holes of different diameters in the middle of them, to cover the above- mentioned glafs, and thereby diminifh the aperture when the greated magnifiers are employed. EE, three thin plates of brafs within the body of the mi¬ crofcope ; one of which is bent femicircularly in the middle, fo as to form an arched cavity for the recep¬ tion of a tube of glafs, the ufe of the other two be¬ ing to receive and hold the Aiders between them. F, a piece ol wood or ivory, arched in the manner of the femicircular plate, and cemented thereto. G, the other end of the body of the microfcope, where a hol¬ low female fcrew is adapted to receive the different magnifiers. H, is a fptral fpring of deel, between the end G and the plates of brafs, intended to keep the plates in aright pofition, and counteraft the long fcrew CC. I, is a fmall turned handle, for the better holding of the inftrument, to fcrew on or off at plea- fure. To this microfcope belong fix or feven magnifying glaffes: fix of them are fet in filver, brafs, or ivory, as in the figure K, and marked 1, 2, 3, 4, 5, 6; theloweft numbers being the greatell magnifiers. L, is the feventh magnifier, fet in the manner of a little barrel, to be held in the hand for the viewing of any larger objeft. M, is a flat flip of ivory, called a fider, with four round holes thro’ it, wherein to place objects between two pieces of glafs, or Mufcovy talc, as they appear dddd. Eight fuch Aiders, and one of brafs, are ufually fold with this microfcope ; fome with objedls placed in them, and others empty for viewing any thing that may offer: but whoever pleafes to make a colleftion, may have as many, as he defircs. The brafs Aider is to confine any fmall ob- I C S. 558.; je6t, that it may be viewed without crufhing or de- Optical ftroying it. Inftrume* N, is a forceps, or pair of plyers, for the taking up of infefts or other objects, and adjufting them to the glaffes. O, is a little hair-brufli or pencil, wherewith to wip any dull from off the glaffes, or to take up any fmall drop of liquid, which one would want to examine, and put it upon the talcs, or ifinglafs. P is a tube of glafs contrived to confine living ob¬ jects, fuch as frogs, fiflies, &c. in order to difeo- ver the circulation of the blood. All thefe are con¬ tained in a little neat box, very convenient for car¬ rying in the pocket. When an objeA is to be viewed, thruft the ivory Aider, in which the faid objedl is placed, between the two flat brafs plates EE : obferving always to put that fide of the Aider where the brafs rings are, far- theft from the eye. Then fcrew on the magnifying glafs you intend to ufe, at the end of the inftrument G; and looking thro’ it againft the light, turn the long fcrew CC, till your objeft be brought to fit yogr eye; which will be known by its appearing perfe&Iy diftinft and clear. It is moft proper to look at it firft through a magnifier that can /hew the whole at once, and afterwards to infpedi the fevera! parts more parti¬ cularly with one of the greateft magnifiers ; for thu* you will gain a true idea of the whole, and of all its parts. And tho’ the greateft magnifiers can ftrew but a minute portion of any objeft at once, fuch as the claw of a flea, the horn of a loufe, or the like, yet by gently moving the Aider which contains theobjedl, the eye will gradually overlook it all. As objects muft be brought very near the glaffes when the greateft magnifiers are made ufe of, be care¬ ful not to fcatch them by rubbing the Aider againft them as you move it in or out. A few turns of the fcrew CC will eafily prevent this mifehief, by giving them room enough. You may change the objefts in your Aiders for what others you think proper, by taking out the brafs rings with the point of a pen-knife ; the ifinglafs will then fall out, if you but turn the Ai¬ ders ; and after putting what you pleafe between them, by replacing the brafs rings you will faften them as they were before. It is proper to have fome Aiders fur- niflied with talcs, but without any objesft between them, to be always in readinefs for the examination of fluids, falls, fands, powders, the farina of flowers, or any other cafual objefts of fuch fort as need only be applied to the outfide of the talc. The circulation of the blood may be eafieft feen in the tails or fins of fifties, in the fine membranes be¬ tween a frog’s toes, or beft of all in the tail of a water-newt. If your objeft be a fmall fifti, place it within the tube, and fpread its tail or fin along the fide thereof: if a frog, choofe fuch an one as can but juft be got into your tube ; and, with a pen, or fmall ftick, expand the tranfparent membrane between the toes of the frog’s hind foot as much asyou can. When your object is fo adjuft^d, that no part of it can in¬ tercept the light from the place you intend to view, unferew the long fcrew CCj and thruft your tube in¬ to the arched cavity, quite thro’ the body of the mi- ferope; then fcrew it to the true focal diftance, and you will fee the blood paffitig along, its veffels with a rapid motion, and in a moft furprifing manner. The 5586 OPT Optical The third or fourth magnifiers may be ufed for Inftrnments frag3 or fifhes: but for the tails of water-newts, the fifth or fixth will do ; becaufe the globules of their blood are twice as large as thofe of frogs or fifh. The firft or fecond magnifier cannot well be employed for this purpofe ; becaufe the thicknefs of the tube, in which the objedt lies, will fcarce admit }ts being brought fo near as the focal diftance of the mag¬ nifier. $ 5. The Single Microfcope with Reflexion. Plate jN fig. 2, A is a fcroll of brafs fixed upright on a CCXIX. roun(j pedeftal of wood B, fo as to ftand perfedlly firm and fteady. C is a brafs fcrew, that pafies thro’ a hole in the upper limb of the fcroll, into the fide of the microfcope D, and fcrews it fall to the faid fcroll. E, is a concave fpeculum fet in a box of brafs, which hangs in the arch G by two fmall fcrews ff, that fcrew into the oppofite fides thereof. At the bot¬ tom of this arch is a pin of the fame metal, exadlly fitted to a hole /; in the wooden pedeftal, made for the reception of the pin. As the arch turns on this pin, and the fpeculum turns on the ends of the arch, it may, by this twofold motion, be eafily adjufted in fuch a manner as to refledt the light of the fun, of the fky, or of a candle, diredlly upwards through the micro¬ fcope that is fixed perpendicularly over it; and by fo doing, may be made to anfwer almoft all the purpofes of the large double refledling microfcope. The body of the microfcope may'alfo be fixed horizontally, and objedls viewed in that pofition by any light you choofe, which is an advantage the double refledling microfcope has not. It may alfo be rendered further ufeful by means of a flip of glafs, one end of which being thruft thro’ between the plates where the Aiders go, and the other extending to fome diftance, fuch ob- jefts may be placed thereon as cannot be applied in the Aiders : and then, having a limb of brafs that may faften to the body of the microfcope, and extend over the projedting glafs a hollow ring wherein to fcrew the magnifiers, all forts of fubjedls may be examined with great conveniency, if a hole be made in the pedeftal, to place the fpeculum exadlly underneath, and there¬ by throw up the rays of light. The pocket-microfcope, thus mounted, fays Mr Baker, “ is as eafy and pleafant in its ufe; as fit for the moft curious examination of the animalcules and falls in fluids, of the farinse in vegetables, and of the circulation in fmall animals; in fhort, is as likely to make confiderable difcoveries in objedlsthat have fome degree of tranfparency, as any microfcope I have ever feen or heardof.” § 5. Of the Double Ref rafting and Reflefting Micro- fcopes. Double microfcopes are fo called as being a com¬ bination of two or more lenfes. The only advantage which the double refrafting microfcope hath over the Angle one is, that it takes in a larger field of view; and therefore hath yielded to the double reflefting microfcope, which gives a clearer view of objedls, with a greater power of mag¬ nifying at the fame time. F'S- 3* The body of this microfcope AAAA is a large tube, fupported by three brafs pillars kb b) rifing from I C S. Partlll. a wooden pedeftal C; in which pedeftal is a drawer Optical D, to hold the objedl-glafies and other parts of the tnftrumcnts apparatus. A lefler tube ee Aides into the greater, and fends from its bottom another tube f much fmal- ler than itfelf, with a male fcrew g at the end there¬ of, whereon to fcrew the objeft-glafs or magnifier. There are five of thefe magnifiers, numbered 1, 2, 3, 4, 5 ; which numbers are alfo marked on the inner tube, to dir'efl whereabout to place it according to the magnifier made ufe of: but if then it fits not the eye exadlly, Aide the inner tube gently higher or lower, or turn the fcrew of the magnifier gradually, till the objedl appears diftindL The greateft mag¬ nifiers have the fmalleft apertures and the loweft numbers. L, is a circular plate of brafs fixed horizontally be¬ tween the three brafs pillars, and in the centre there¬ of a round hole M is adapted to receive a proper con¬ trivance N for holding ivory Aiders wherein objedls are placed: this contrivance confifts of a fpiral fteel wire confined between three brafs circles, one where¬ of is moveable for the admiffion of a Aider. O is a round brafs plate with feveral holes for placing objedls in, fome of which are ufually furniftied with them at the fhops: bnt two holes are commonly referved for fmall concave glafles, whereon to place a drop of any liquid, in order to view the animalcules, &c. There is alfo a piece of white ivory, and a piece of black ebony, of the fame fize and Aiape as the holes for ob¬ jedls : the ivory is for holding fuch opaque objedls as are black, and the ebony fuch as are white, by which contrariety of colours they will be feen more diftindl- ly. At the bottom of this objedl-plate is a button to flip into a flit P, that fits it, on the circular plate of brafs: and by turning it round on this, all the ob¬ jedls may be examined fucceffively with very little trouble. is a concave fpeculum fet in a box of brafs, and turning in an arch R, upon two fmall fcrews / r. From the bottom of the arch comes a pin, which be¬ ing let down into a hole /, in the centre of the pede¬ ftal, enables the fpeculum to turn either vertically or horizontally, and to refledl the light diredlly upwards on the objedl to be viewed. V, is a plano-convex lens, which by turning on two fcrews * *, when the pin at the bottom of it is placed in the hole W, for its reception in the circular plate L, will tranfmit the light of a candle to illuminate any opaque objedl that is put on the round piece of ivory or on the ebony for examination: and it may be moved higher or lower, as the light requires. This glafs is of fervice to point the funfliine or the light of a candle upon any opake objedl, but in plain day-light is of no great ufe. X, is a cone of black ivory, to faften on a fhank underneath the brafs circular plate L, princi¬ pally when the firft or fecond magnifier is made ufe of, and the objedl very tranfparent: for objedls are rendered much more diftindlly vifible, by intercepting fome part of the oblique rays which come from the fpeculum. The brafs fifli-pan Y is to faften any fmall fifh upon, to fee the circulation of the blood in its tail. For this purpofe, the tail of the fifh muft be expanded acrofs the oblong hole at the fmalleft end of the pan: then by flipping the button on the back- fide of the pan into the flit JP thro’ the circular plate OPTICS . Plate OCXJX. . PartHI. OPT Optical L, the fpring that comes from the button will make Inftrumcnts ;t ftCady, and prefent it well to view. But if it be a frog, a newt, or an eel, in which the circulation is defired to be Ihewn, a glafs tube i is fitteft for the pur- pofe. The tail of a newt or eel, or, in a frog, the web be¬ tween the toes of the hind-feet, are the parts where it may be feen beft. When the objedt is well expanded on the infide of the tube. Aide the tube along under the circular brafs plate L, (where there are two fprings and a cavity made in the fhank to hold it), and bring your objedt diredtly under the magnifier. There are three of thefe glafs tubes fmaller one than another, and the fize of the objedt muft diredl which of them is to be ufed ; but, in general, the lefs room the creature has to move about in, the eafier will it be managed. The cell 2, with a concave and a plane glafs in it, is intended to confine fleas, lice, mites, or any fmall living objedls, during pleafure ; and by placing it over the hole M, in the middle of the circular brafs plate, they may be viewed with much conveniency. Three loofe glaffes, viz. one plane, and two concave, belong alfo to this microfcope ; and are defigned to confine objeSs, or to place them upon occafionally. The long fteel wire 3, with a pair of plyers at one end, and a point on the other, to hold faft or ftick objedts upon, flips backward or forward in a ihort brafs tube where¬ to a button is faftened, which fits into the little holez, near the edge of the brafs plate L : and then the ob- jedl may be readily brought to a right pofition, and a light be call upon it either by the fpeculum under¬ neath, or, if it be opake, by the plano-convex lens V. 4, Is a flat piece of ivory called a Jlider, with four round holes thro’ it, and objedls placed in them, between Mufcovy talcs or ifinglafs, kept in by brafs wires. It is proper to have a number of thefe Aiders, filled with curious objedts, always ready, as well as fome empty ones for any thing new that offers. When made ufe of, thruft them between the brafs rings of the contrivance on purpofe for them, which flioots into the round hole M, in the centre of the brafs plate L. This keeps them fteady, and at the fame time permits them to be moved to and fro for a thorough exami¬ nation. 5, Is a little round ivory box to hold pieces of ifinglafs for the Aiders ; 6, a fmall hair-brulh to wipe off any duft from the glafies, or to apply a drop of any liquid; 7, a pair of nippers to take up any objedt to be examined. § 6. The Microfcope for Opaque Ohjefis. This microfcope remedies the inconvenience of ha¬ ving the dark fide of an objedl next the eye, which formerly was an unfurmountable objedtion to the ma¬ king obfervations on opaque objedts with any confider- able degree of exadtnefs or fatisfadtion : for, in all other contrivances commonly known, the nearnefs of the inftrument to the objedl (when glafles that mag¬ nify much are ufed) unavoidably overfliadows it fo much, that its appearance is rendered obfcure and in- diftindt. And, notwithflanding ways have been tried to point light upon an objedt, from the fun or a candle, by a convex glafs placed on the fide thereof, the rays from either can be thrown upon it in fuch an acute angle only, that they ferve to give a confufed glare, but are infufficient to afford a clear and perfect ICS. 5587 view of the objedl. But in this microfcope, by means Optical of a concave fpeculum of filver highly polifhed, in h'flrumen;; whofe centre a magnifying lens is placed, fuch a ftrong and diredt light is refledted upon the objedl, that it may be examined with all imaginable cafe and pleafure. The feveral parts of this inftrument, made either of brafs or filver, are as follow. Thro’ the firft fide A, pafles a fine fcrew B, thephte other end of which is faftened to the moveable fide C. CCX1X. D is a nut applied to this fcrew, by the turning offiS,4* which the two fides A and C are gradually brought together. E, is a fpring of fteel that feparates the two fides when the nut is unfcrewed. F a piece of brafs, turning round in a focket, whence proceeds a fmall fpring-tube moving upon a rivet, thro’ which tube there runs a fteel wirej one end whereof termi¬ nates in a Aiarp point G, and the other hath a pair of plyers H faftened to it. The point and plyers are to thruft into, or take up and hold, any infedl or objedl ; and either of them may be turned upwards, as beft fuits the purpofe. I, is a ring of brafs, with a female fcrew within it, mounted on an upright piece of the fame metal; which turns round on a rivet, that it may be fet at a due diftance when the leaft magnifiers are employed. This ring receives the fcrews of all the magnifiers. K, is a concave fpeculum of filver, po- liftied as bright as pofiible; in the centre of which is placed a double convex lens, with a proper aperture to look thro’ it. On the back of this fpeculum, a male fcrew, L, is made to fit the brafs ring I, to fcrew into it at pleafure. There are four of thefe concave fpecula of different depths, adapted to four glafles of different magnifying powers, to be ufed as the ob¬ jedts to be examined may require. The greateft mag¬ nifiers have the leaft apertures. M, is a round objedl- plate, one fide of which is white and the other black : The intention of this is to render objedls the more vi- fible, by placing them, if black, on the white fide, or, if white, on the black fide. A fteel ring, N, turns down on each fide to make any objedl faft; and if- fuing from the object-plate is a hollow pipe to fcrew it on the needle’s point G. O is a fmall box of brafs, with a glafs on each fide, contrived to confine any li¬ ving objedl, in order to examine it: this alfo has a pipe to fcrew upon the end of the needle G. P, is a turned handle of wood, to fcrew into the inftrument when it is made ufe of. a pair of brafs plyers to take up any objedl, or manage it with conveniency. R is a foft hair-brufh for cleaning the glaffes, &c. S, is a fmall ivory box for ifinglafles, to be placed, when wanted, in the fmall brafs box O. When you would view any objedt with this micro¬ fcope, fcrew the fpeculum, with the magnifier you think proper to ufe, into the brafs ring I. Place your objedl, either on the needle G in the plyers H, on the objedl-plate M, or in the hollow brafs box O, as may be moft convenient: then holding up your inftrument by the handle P, look againft the light thro’ the mag¬ nifying lens ; and by means of the nut D, together with the motion of the needle, by managing its lower end, the objedl may be turned about, raifed, or de- prefled, brought nearer the glafs, or removed farther from it, till you hit the true focal diftance, and the light be feen ftrongly refledled from the fpeculum up¬ on the objedl, by which means it will be ftrewn in a manner 5588 OPT Optical manner furprifingly difHnd and clear; and for this Jnftniments purp0fe the light of the flcy or of a candle will anfwer very well. Tranfparent objefts may alfo be viewed by this microfcope : only obferving, that when fuch come under examination, it will not always be proper to throw on them the light refle&ed from the fpeculum ; for the light tranfmitted thro’ them, meeting the re- fleded light, may together produce too great a glare. A little pra&ice, however, will fliew how to regulate both lights in a proper manner. $ 7, The Solar Microfcope. This inftrument is compofed of a tube, alooking- glafs, a convex lens, and Wilfon’s Angle pocket mi¬ crofcope before defcribed. The fun’s rays being di¬ rected thro’ the .tube, by means of the looking-glafs, upon the objed, the image or pidure of the objed is thrown diftindly and beautifully upon a fcreen of white paper, or a white linen Iheet, placed at a pro¬ per diitance to receive the fame ; and may be magni¬ fied to a fize not to be conceived by thofe who have not feen it: for the farther the fcreen is removed, the larger will the objed appear ; infomuch, that a loufe may thus be magnified to the length of five or fix feet, or even a great deal more; though it is more diftind, when not enlarged to above half that fize.—The ap¬ paratus for this purpofe is as follows, crxx. ^ a ^luare woo by which it is moveable vertically. * E, is a hollow fquare focket, with F, a fcrew, by which it is fixed to the part at D. DQR is a (trong brafs pillar or (land. S, T, V, the tripod, or three feet, on which it Hands. GHI is a ftage on which objedls of different forts are placed to be viewed. K, is a ftrong fcrew by which the ftage is rendered moveable horizontally. MN, are two brafs fockets, conne&ed by an adjuft- ing fcrew, and moveable up and down upon the fquare part of the (land. O is a fcrew for fixing the focket M. P is a long adjufting fcrew by which the focket N is moveable, and the objefts upon the ftage adjufted to the view. W is a concave mirror, or fpeculum, fixed at X, juft under the central part of the ftage, for illu¬ minating tranfparent objeds. Y is a concave lens moveable at Z, in a fpring focket; by this lens opaque bodies are fufficiently enlightened for the view. This compound microfcope is in the bed manner adapted to view tranfparent objedls; for if they are fuch as can be put into the concave glafs in the middle of the ftage at H, then they will be fufficiently en¬ lightened by the refle&or W below, in one fide of which is a plane fpeculum, and in the other a concave one, as both forts are occafionally neeeffary. If the tranfparent obje&s are fuch as may be included between talcs in the ivory Aiders, then there is a part J'S’ ABCD, called the f ider-holder, which is fitted to the hole at H in the middle of the ftage, and in which all the variety of objedls in Aiders may be viewed to great perfedlion by refiedted light from the fpeculum W below.. ICS. 5589 As fome curious experiments with tranfparent ob- Optical jedts require the light to be very pure, and adjufted to Inflruments a proper degree, there is an inverted cone of brafs, ABC, to be placed in the under part of the hole at Fig. 3. H by its broad end or bafe AC; and by the narrow end B only the interior and purer light contained in the upper and denfer part of the large cone of rays re¬ fiedted by the fpeculum W, can illuminate the objedls to be viewed. This cone is indeed of more immediate ufe in the fingle microfcope, to be mentioned by and by. Thus, it is plain, in one or other of thefe ways all kinds of tranfparent objedts are to be viewed in the utmoft perfedxion. In this conftrudlion it is alfo as evident, that every opaque objedt may be ftiewn as well in this as in that which is ufually called the opaque microfcope: becaufe here is all the fame apparatus for that purpofe, and much more ; for this is both a fingle and compound opaque microfcope. Thus, if any opaque objedt be laid upon the glafs at H, it may be very ftrongly illuminated by the lens Y, moveable higher or lower in the focket Z, to make the light upon the objedt greater or lefs, as occafion requires. In this cafe you have the advantage of a large and delightful field of view, and objedts of all (hapes and fizes are immediately viewed upon the (lage GHI, as it is fo eafily moved up and down by the Ai¬ ding fockets MandN, faftened in any pofition by ths fcrew O, and adjufted for the mod accurate infpec- tion by the fcrew P. In many cafes it may be requifite to view light-co¬ loured objedts upon a dark ground, and the contrary: therefore, to anfwerfuch purpofes, there is provided a round flat piece of ivory, with one fide white and the other black, fitted into the hole at G, and to be taken in and out at pleafure. To anfwer thefe purpofes dill more generally, there is a pair of plyers, AB, moveable in a brafs fpring Fig. 4, focket at C, and by the (hank at D it is fitted in the hole of the ftage at I, where it has a horizontal mo¬ tion, and alfo a vertical motion (up and down) by its joint at E. By the pincers at the end A any objedt may be very readily adjufted to the view, and illumin¬ ed by the lens Y. Alio at the other end of the plyers B, there is a fmall cylindric piece of ivory F ferewed on, with one end black, the other white, for the above- mentioned purpofes. But oftentimes objedts will be found which require the ufe of the plyers AB, and are feen to the greateft advantage by light refledted upon them ; for which purpofe a fmall concave metallic fpeculum AB is ferew¬ ed into the end CD of a tube CDEF, which is Fig. s. made to go on upon the pipe of the microfcope; and the large cone of refledted light from the mir¬ ror W will pafs through the hole H to this fmall concave AB, by which it will be refledted upon the objedt in the plyers at A, but more efpecial- ly Upon the ivory at F, where exceeding fmall obr jedts require the greateft degree of light they can bear. Further, to make this microfcope anfwer all the ends of a fingle opaque microfcope, there is a brafs piece AB, with a fquare hole-or focket, to go on upon the Fig. C. (hank at D (fig. 1.) when the body of the microfcope ABC is taken off, and is there made fad by the fcrew G. 559° 0 P . Optical C. To tills is annexed a ftrong brafs ring DE, into InftrumentswhlCh are fcrewed the fame Liberkhuns, as they are called, or concaves with a fmall lens in the middle of each, as are ufed in the fingle opaque microfcope ; and being applied to objefts on the ftage GHI, or in the plyers, they are viewed in the fame mannner here as they are there; with this additional advantage, that in the prefent microfcope, the light is much more intenfe from the fpeculum W, than the common light but once refle&ed in the ufual form of this inftrument. Laftly, every thing (hewn in the aquatic microfcope is to he feen equally in this ; becaufe, fince the hole at H in the ftage is very large, it will admit of a con¬ cavity fufficiently capacious for any purpofes of view¬ ing objefts in water, of any fort whatfoever. And not only the magnifiers, but the mode of applying them, is nearly the fame here as in thofe of the common form. But in this conftru&ion, you have both the fingle arid compound aquatic microfcope: for the ftage GHI being moveable horizontally, and the magnifier at A moving vertically on the joint at D, it is plain, every part of the water in the concave glafs at H may be brought under it, and the moft minute obje&s well enlightened by the conCave AB, and ftiewn with great diftinclnefs. The other parts of the apparatus are common to all microfcopes. Every body knows the ufe of the ivory Aiders, for holding and applying tranfparent objefts as above directed, (fig. 7.). But in fig. 8. you have the form of a brafs Aider, with feveral fmall glafs con¬ caves fixed in one fide, and over them a fiip of clear plain glafs is made to Aide in the frame, and thereby to confine in the hollow of the glafles very fmall living objefts, as a flea, loufe, mite, &c. and prevent their crawling out of the field of view. There is alfo what is called a bug-bo-x, confiding of two parts: the lowed contains a large concave; and ‘ the upper part contains a plane glafs, which, being fcrewed upon the concave, will confine any larger animal, as a bug, an ant, a fpider, a fmall fly, &c. As the circulation of the blood is one of the nobleft experiments of the microfcope, fo ample jtrovifion is made for it by a fet of glafs tubes of different fizes for applying the tranfparent parts of proper obje&s fer that purpofe, fuch as fmall fifh, tadpoles, and water- newts, the bed fubjeA of all; fuch a tube is AB (fig. 9.) It being neceflary to dop the open end B, when the animal is in, with a cork, there is a fmall hole at the other end A to give air to the animal. Thefe tubes are applied to the hole H in the ftage by two fteel fprings on the under part, bent to receive them. In cafe it be required to view the circulation in the tail of a large fifh, as a gudgeon, loach, &c. thtre is an inftrument of brafs called the fifo-patt) (fig. 10.) contrived of a proper form to hold and confine it; where ABD is the incurved plate to receive the body of the fifh; CFG is a ribbon to tie the fifh to the faid plate or pan, and is kept tight by a fpring behind at H. At the end AD, is a long tranfverfe hole or flit, over which the tranfparent tail of the fifh is placed; and then by the {hank at E, on the under fide, it is put upon the ftage thro’ a hole at I, and there eafily adap¬ ted to the magnifier A, by moving it every way un¬ der the fame. TICS. § 9. Clark's Improved Pocket Microfcope. This is reprefented in Plate CCXX. where ABC DEE (fig. 2. n° 1.) is a box three inches broad, four inches long, and one inch deep, covered with fhagreen, and having the lid open, which when fhutis faftened by clafps as in the figure. This box ferves for the pe- deftal as well as cafe of the inftrument. abed, Is a folid piece of wood, fixed in the middle of the box; on which is fcrewed a brafs plate ef having in the middle a female ferew for holding the other parts now to be deferibed. n° 2. Is a piece of brafs of the fhape reprefent¬ ed in the plate, having a male ferew at «, anfwering to the female one abovementioned at and by which this part is firmly fixed upright in the middle of the box. On the lower part of this piece of brafs is fa¬ ftened, but in fuch a manner as to be moveable at the joint a femicircle of brafs £ f, in which is a concave fpeculum iiHy ground to a focus of about eight inches: it is moyeable in the ring, by means of two pivots ; and as the ring itfelf is alfo moveable, it is plain that the fpeculum may be moved to a proper diftance from the ftandard. The face of it is placed next the ftandard when the inftrument is put into the cafe, in order to prevent the polifhed furface from in¬ jury. v Is a piece of folid brafs, which goes into a dovetail flit in the part next to be deferibed, and which Mr Clark calls the Jlage. This confifts of two pieces, n° 3. One of thefe, x xx .v, is a parallelogram of brafs, in which the other part yzyz Aides up or down by means of the ferew mn. From the upper part of this, proceeds at right angles another piece 91 zr s. This is formed of two pieces of brafs riveted at y and z ; and joined to each other at their extremities by the crofs piece rs. Upon this Aides another piece 1, 2, 3, 4, having in it a round hole 5, and which can be made to approach either to y-z or to rs as occafion re¬ quires. This part, by means of the dovetail flit at xx, may be put on the folid piece of brafs at y of the former, and fecured in a perpendicular pofition on the top of it. The laft; part of this microfcope is reprefented n° 4. It confifts of a folid piece of brafs 0p q t, to which is fixed at right angles the piece op v; is a fmall plane fpeculum, with the refle&ing fide downwards, and, by means of a joint, capable of being raifed up or let down as the obferver finds neceffary. To the under fide Part HI. It is often required to fee what many fmall objefts OpticalT are, and how they are beft difpofed in Aiders, glaffes, Inftrumea tubes, &c. for which purpofe there is a hand-mag¬ nifier ABC, (fig. 11.) containing a lens of about one inch focal diftance, to be ufed upon all fuch occa¬ fion 3. Befides the above particulars, there is a pair of nip¬ pers (or forceps) to take "up fmall obje&s, in order to place them on the ftage, between the talcs, &c. alfo a camel-hair brufh, for cleanfing talcs, glafs, See. A fmall wire, with a fpiral ferew at the end, for holding cotton, &c. for cleanfing the glafs tubes. A little ivory box with fpare talcs, and wires to faften them in the Aiders. A piece of (hammy leather is ufeful up¬ on all occafions for wiping the glades of every fort, as it will cleanfe them well without hurting their fur- faces. Optics . Plate ecxx Part III. OPT Optical fide of the fore*part of this is placed a fmall brafs Jnftrumentscjrc|e> cdges of which appear at « and a, and ""which is fully reprefented in n° 5. Round this circle, the magnifiers are difpofed, and over againft each of them is engraved its magnifying power, ex- preffed by x, 2, 3, 4, 5, the higheft numbers magnify¬ ing mod. This circle is movable; and fo difpofed, that, as it turns round, the magnifiers appear fuccef- fively through the hole at at the fame time that the power of each is Ihewn by the cipher which appears through the little fquare hole at ), n° 4. This whole part of the machine Aides up and down on the back of the other, by means of a dovetail; and thus, though the part 0 p ^ v is always above and parallel to the ftage, yet it may be brought nearer to it or removed farther off at pleaftire. On the folid back plate are marked the numbers Tj 2, 3, 4, 5, to fhew the foci of the different mag- ■ , nifiers. Concerning the proper method of ufing this microfcope, Mr'Clark gives the following direftions. When the cafe is opened, take out the microfcope, which confifts of two feparate parts ; fcrew the under part (on which the fpeculum is) into the brafs plate in the infide of the cafe, which is the bafe for the inflru- ment while in ufe.—Put the other end into the dove¬ tail flit behind the handle of the adjufting fcrew m », n° 3. place the microfcope fo as the fpeculum may front the light ; then gently move up the back part by the button for that purpofe, till the figure x, on the plate opqt, (n° 4.) appears juft above the ftage: then turn round the circular plate which contains the magnifiers, being five in number, till 1 appear in the fquare hole a-top. Put the Aider with the objefts into the ftage ; give the concave fpeculum fuch an in¬ clination as to throw the rays through the object im¬ mediately under the magnifier: thereabout diftin£t vifion will be had ; if not entirely fo, a turn or two of the adjufting fcrew will either raife or deprefs the ftage, as the eye or objeft requires: and fo on with «ach magnifier and correfponding figure, always taking care that the fpeculum be in fuch a fituation as to throw the light properly up. The Aider for opaque objeAs confifts of three divifions ; firft, ebony, for laying all white or light- coloured obje&s on, fuch as feeds, fands, mineral, &c. The fecond divifion ivory, for all dark and black bodies. The third divifion glafs, which opens and fhuts ; when open, for the circulation of the blood in tadpoles, &c. when fhut, for confining any live objeft to be examined, and for all kinds of animalcules in fluids, folmions of falls, &c. Likewife there are on the. fide of the above Aider, a pair of fmall forceps, that turn out at pleafure, to hold any opaque or tranfparent objedf, fuch as a fly, fpider, &c. which may be viewed with the aid of one or both fpeculums to great advantage. See n° 6. When this microfcope is employed for examining an opaque objeft, the upper fpeculum muft be bent down to fuch an angle as to throw the rays rtfle&ed from the under fpecultim upon the opaque objeift in view: with the fun or candle-light, thofe two fpe¬ culums have a moft delightful effed. The rays from the under fpeculum, pafiing through the fquare opening yz, t, 2, (n° 3.) behind the ftage, fall on the fmall up¬ per plane fpeculum, which, moving on an axis, may , Vot-Vril. 1 I C S. 5591 be placed in a dife&ion fo as to illuminate the opaque Optical objedl with the whole light proceeding from the large Inftrum{'ll!S concave fpeculum. In this operation all the magni¬ fiers but n° 5. may be ufed with fucccfs and fatisfa&ion. § 10. Of Extempore Microfcopes. For thofe who cannot conveniently procure the apparatus of any of the above-mentioned microfcopes, it may afford fome entertainment to try the magnify¬ ing power of fmall globules of water, which in fome cafes is very confiderable. The inventor of this me¬ thod of viewing objefls was Mr Stephen Gray, who gives an account of it in the Philofophical Tranfac- tions N° 221, 223. “ Having obferved, fays he, fome irregular particles within the glafs globules (for microfcopes), and finding that they appeared diftinft, and prodigioufly magnified when held clofe to my eye ; I concluded, that if I conveyed a fmall globule of water clofe to my eye, in which there were any opacous or lefs tranfparent particles than water, I might fee them diftinftly. I therefore took on a pin a fmall portion of water, which I knew to have in it fome minute animals, and laid it on the end of a fmall piece of brafs wire that then lay by me, about of an inch in diameter, till there was formed fomewhat more than an hemifphere of water. Then keeping the wire ercft, I applied it to my eye, and, ftanding at a proper diftance from the light, I faw them and fome irregular particles, as I had predi&ed ; but moftly enormouAy magnified. For, whereas they were fcarce difcetnable by my glafs microfcope, they appeared within the globule not much different in form, nor lefs in magnitude, than ordinary peas. They cannot be well feen by day-light, unlefs the room be darkened; but mod diftinftly by candle-light. They may alfo be very well feen by the light of the full moon.” But Mr Gray tells us, that thefe little animals will appear more diftindtly, if drops of water be con¬ veyed by a pin’s point into a round hole made in a brafs plate whofe thicknefs is about one tenth of an inch, and the diameter of the cylindrical hole a little lefs than half a tenth; obferving to fill it till near an hemifphere of water be extant on each fide of it. Now, fuppofing the axis of this cylinder of water to be terminated by equal fpherical furfaces, and to be exaftly equal to three diameters of the fpheres of thofe furfaces; in that cafe the little animals feen by reflec¬ tion from the farther furface, will appear juft twice as big in diameter, as if they were placed in the focus of one of thofe fpheres of water, and were feen thro' it as in common microfcopes. His defcription of the animalcules thus obferved is curious. “ They are (fays he) of a globular form, and but little lefs tranf¬ parent than the water they fwim in. They have fometimes two dark fpots diametrically oppofite ; but thefe are rarely feen. There are fometimes two of thefe globular infefts flicking together, and the place of junction is opacous: poflibly they may be in the adt of generation. They have a twofold motion ; a fwift progreflive regular one, and at the fame time a rotation about their axes, at .right angles to the dia¬ meter that joins their dark fpots ; but this is only feen when they move flowly. They are almoft of an .incredible minuteijefs. Mr Leeuwenhoek is moderate 31 P enough optical enough in his computation, when he tells us that he Iiiftrumemspaw infe&s in water fo fmall that 30,000 ofjhern could fcarcely equal a grain of coarfe fand. But I believe it will feem a paradox to him when he is told, that he may fee them by only applying his eye to a portion of water wherein they are contained. I have examined many tranfparent fluids, as water, wine, brandy, vinegar, beer, fpittle, urine, &c. and do not remember to have found any liquors without thefe infe&s. But I have not feen many in motion, except in common water that has flood, for fometimes a longer, at others a fnortcr time. In the rivers, after the water has been thickened by rain, there are fuch infinite numbers of them, that the water feems in great part to owe its opacity and whitenefs to thofe globules. Rain-water, as foon as it falls, has many, and fnow- water has more of them. The dew that ftands on glafs windows has many of them : and for as much as rains and dews are continually afcending and defcend- ing, I believe we may fay the air is full of them. They feem to be of the fame fpecific gravity with the water they fwim in ; the dead remaining in all parts of tlse water. Of the many thoufands that I have feen, I could difcern no fenfible difference in their dia¬ meters ; they appear of equal bigneffes in water that has been boiled: they retain their ftiapes, and will fometimes revive.” Plafe. The fame ingenious author deferibes another water- CCXXII. microfcope of his own invention, as follows. “ AB “S' I call the frame of the microfcope; it may be about of an inch in thicknefs. At A there is a fmall hole near of an inch in diameter, in the middle of a fpherical cavity about ^ of an inch in diameter, and in depth fomewhat more than half the thicknefs of the brafs. Oppofite to this, at the other fide of the brafs, there is another fpherical cavity, half as broad as the former; and fo deep as to reduce the circum¬ ference of the fmall hole above-mentioned, almoft to to a (harp edge. In thefe cavities the water is to be placed, being taken upon a pin or a large needle, and conveyed into them till there be formed a double con¬ vex lens of water ; which, by the concavities being of different diameters, will be equivalent to a double convex lens of unequal convexities. By this means I find the obje& is rendered more diftinft than by a plano-convex of water, or by a double convex formed on the plane furfaces of a piece of metal. CDE is the fupporter whereon to place the obje or jo ■h> or 40 tV> or 3° j-, or 20 !5 H ’3 12 11 26 40 53 57 61 66 72 80 . 88 100 “4 133 160 200 266 400 800 Magnifies theSuper- ficies. 256 400 676 1,600 2,809 3»249 3.721 4.356 5,184 6,400 7.744 10,000 12,996 17,689 25,600 40,000 70,756 160,000 640,000 Objeft. 4,096 8,000 64,000 148.877 rtS’m 226,981 287,496 373.248 512,000 681,472 1,000,000 i,48i,544 2,352,637 4,096,000 8,000,000 18,821,096 64,000,000 512,000,000. The greateft magnifier in Mr Leeuwenhoek’s cabinet of microfcopes, prefented to the Royal Society, has its focus, as nearly as can well be meafured, at one-twentieth of an inch diftance from its centre; and confe¬ quently magnifies the diameter of an objed 160 times, and the fuperficies 25,600. But the greateft mag¬ nifier in Mr Wilfon’s fingle microfcopes, as they are now made, has ufually its focus at no farther diftance than about the 50th part of an inch; whereby it has a power of enlarging the diameter of an objed 400, and us fuperficies 160,000 times. 2 31 P 2 The Optical The magnifying power of the folar microfcope In liniments mujj calculated in a different manner; for here the difference between the focus of the magnifier and the diflance of the fcreen or. fheet whereon the image of the objeft is caft, is the proportion of its being mag¬ nified. Suppofe, for inftance, the lens made ufe of has its focus at half an inch, and the fcreen is placed at the diflance of five feet, the objedt will then ap¬ pear magnified in the proportion of five feet to half an inch: and as in five feet there are 120 half-inches, the diameter will be magnified 120 times, and the furperficies 14,400 times; and, by putting the fcreen at farther dillances, you may magnify the objedt almoft as. much as you pleafe ; but Mr Baker advifes to regard diftindlnefs more than bignefs, and to place the fcreen juft at that diftance where the obje& is feen moft diftindt and clear. With regard to the double refledling microfcope, Mr Baker obferves, that the power of the objedl-lens is indeed greatly increafed by the addition of twoeye- glafles; but as no objedl lens can be ufed with them of fo minute a diameter, or which magnifies of itfelf near fo much as thofe that can be ufed alone, the glaffes of this microfcope, upon the whole, magnify little or nothing more than thofe of Mr Wilfon’s fingle one; the chief advantage arifing from a com¬ bination of lenfes being the fight of a larger field or portion of an objedt magnified in the fame degree. $ 12. To find out the real Size of Objefts fein by Microfcopes. Though, by the diredlions already given, the mag- sifying powers of microfcopes,may be eafily calcu¬ lated ; yet if we examine extremely minute objedls, the real fize of them will ftill remain uncertain. For, though we may know that they are magnified fo many thoufand times, we can by that make but a very imperfedl computation of their natural and true lize ; nor indeed can we come to any certain conclufion as to that, but by the mediation of fome larger objedt whofe dimenfions we really know. For as bulk itfelf is merely comparative, the only way we can judge of the bignefs of any thing is by comparing it with fome- thing elfe, and finding out how many times the lefler is contained in the larger body. The plained and moft pradticable methods of doing this in microfcopical ob- jedts are the following. I. Mr Leeuwenhoek’s method of computing the fize of falls in fluids, of the animalcules in femine mafculino, in pepper-water, &c. was by comparing them with a grain of fand. By this, however, we muft underftand the coarfe fea-fand, ufually called fcouring-fand, which is equal in bignefs to feveral grains of writing fand. But to make our caculations ftill more certain, we muft fuppofe them to be of fuch a fize, that too of them placed in a row (hall extend an inch in length. Mr Leeuwenhoek then made his calculations in the following manner. p)ate He viewed thro’ his microfcope a fingle grain of oohcil. fand, which we will fuppofe to be magnified as the fig. i. round figure ABCD. Then, obferving an animal¬ cule fwimming or running acrofs it, (which fuppofe to be of the fize 1,) confidering and meafuring this, by his eye, he concludes, that the diameter of this animalcule is only xV of the diameter of the grain I C S. Partin; of fand : confequently, according to the common Optical rules, the fuperficies of the grain of fand is 144 times,Illftlument? and the whole contents 1728 times, larger than the ani¬ malcule. Suppofe again, that he fees among thefe another and fmaller fpecies of animalcules; one of which, 2, he likewife meafures by his eye, and computes its dia¬ meter to be four times lefs than the former: then, ac¬ cording to the foregoing rules, the furface of this fe- cond animalcule will be 16, and the whole bulk 64, times lefs than the animalcule 1. If farther, upon a nicer view, he difeovers a third kind of animalcule, 3, fo exceedingly minute, that, examining it-in the former manner, lie concludes the diameter to be 10 times fmaller than the fecond fort; it will then follow, that 100c of them are only equal in bignefs to one of that fort. Hence, of the firft fort, 1728 would be contained in a grain of fand ; of the fecond, 110,592 ; and of the third, 110,592,000. In this manner may the comparative fize of fmall objefts be judged of with tolerable certainty : parti¬ cularly in the folar microfcope; fince the image of the objedt and of the grain of fand, or whatever elfe is thought proper to compare with it, may be really mea- fured by a ruler or a pair of compafies, and the diffe¬ rence of their diameters moft exadlly found. 2. Mr Hooke deferibes his method in the follow¬ ing words. “ Having redtified the microfcope to fee the defired objedl thro’ it very diftindlly ; at the fame time that I look upon the objedl thro’ the glafs with one eye, I look upon other objedls at the fame di¬ ftance with my other bare eye : by which means I am able, by the help of a ruler divided into inches and fmall parts, and laid on the pedeftal of the microfcope, to caft as it were the magnified appearance of the ob¬ jedl upon the ruler, and thereby exadtly to meafure the diameter it appears of thro’ the glafs; which be¬ ing compared with the diameter it appears of to the naked eye, will eafily afford the quantity of its be¬ ing magnified.” This method is recommended by Mr Baker as very good for multitudes of objefts; and he declares from his own experience, that a little pradlice will render it exceedingly eafy and pleafant. 3. Another very curious method for this purpofe is deferibed by Dr Jurin in his Phyfico-Mathematical Differtations. Wind a piece of the fined filver-wire you can get a great many times about a pin, or fome other fuch (lender body, fo clofely as to leave no in¬ terval between the wire-threads; to be certain of which, they muft be carefully examined with a glafs. Then, with a fmall pair of compaffes, meafure what length of pin the wire covers; and applying the com¬ paffes with that meafure to a diagonal fcale of inches, you will find how much it is; after which, by count¬ ing the number of wire-rounds contained in that length, you will eafily difeover the real thicknefs of the fingle wire. This being known, cut it into very fmall pieces ; and, when you examine the obje£l, if it be opaque, drew fome of thefe wires upon it; if tranf- parent, under it; and by your eye compare the parts of the objedl with the thicknefs of fuch bits of wire as lie fairdt to the view. By this method, Dr Jurin obferv.ed, that four globules of human blood would generally cover the breadth of a wire which he had found to be part of an inch ; and confequently Part III. OPT Optical that the diameter of a fmgle globule was r-jrar^tli of [nflmmenlsan . which Was alfo confirmed by Leeuwenhoek, from obfervations made on the blood with a piece of the fame wire. 4. Mr Martin in his Optics gives another method fufficiently eafy. On a circular piece of glafs, let a number of parallel lines be carefully drawn, with the fine point of a diamond, at the diftance of ^th of an inch from each othert If this be placed in the focus of the eye-glafs of a microfcope, the iq^age of the ob- jeft will be feen upon thefe lines, and the parts there¬ of may be compared with the intervals: whereby its true magnitude or dimenfions may be very nearly known ; for the intervals of thefe lines, tho’ fcarce difcernible to the naked eye, appear very large thro* the microfcope. A contrivance of this kind may alfo be invented for fuch microfcopes as a glafs cannot be applied to in the above manner, by placing it under or behind the objeft, which will anfwer the fame pur- pofe. Here it will be eafy to find what proportion an objeft, or any part thereof, bears to an interval be¬ tween two lines, and then determine it in parts of an inch : for if the width of an objedf appears juft one interval, we fhall know it to be juft one fortieth part of an inch ; if half an interval, the 80th ; if a quar¬ ter of an interval, the 160th; if one fifth, only the 200th part of an inch. 5. Dr Smith has an invention fimilar to this for taking exa6t draughts of objefts viewed in double micro¬ fcopes : for he advifes to get a lattice made with fmall filver wires, or fmall fquares drawn upon a plane glafs by the ftrokes of a diamond, and to put into the place of the image formed by the objeA-glafs. Then, by transferring the parts of the objeft feen in the fquares of the glafs or lattice upon fimilar correfponding fquares drawn upon paper, the pidture thereof may be exactly taken. A micrometer may alfo be applied to microfcopes of the fame form with thofe applied to telefcopes; for by opening the hairs of the micrometer till they exadfly correfpond to a certain length, fup- pofe x^th of an inch, and by obferving the number of revolutions in this opening, the diameter of any other objeft, anfwering to a known number of revo¬ lutions, may be found by the golden rule. $13. Of the Field of Flew in Microfcopes. This is always in proportion to the diameter of the lens made ufe of, and its power of magnifying, by which it may be determined : fince, if the lens is ex¬ tremely fmall, it magnifies a great deal, and confe- quently a very minute portion of an objedt only can be diftinguilhed thro’ it; for which reafon the greateft magnifiers never fhould be employed but for the moft minute objedls. This confideration will dired to the life of fuch magnifiers as are moft proper to be em¬ ployed, which is of the utmoft confequence in micro- fcopical obfervations. On this fubjed Mr Baker gives the following ftiort rule, viz. that the field of view dif¬ fers not greatly from the fize of the lens; and that the whole of any objed much beyond that fize, cannot be conveniently viewed thro’ it. There is fome diffe¬ rence, as to the vifible area of an objed, as feen thro’ fingle or double microfcopes ; for the double fhew a larger portion of it than the fingle, tho’ mag¬ nified as much* ICS. 5595 Optical § 14. Of Microfcopic Objefls, and the Method of pre- Inftrunients paring them for being examined. Mr Hooke gives a general account of microfcopic objeds under the following denominations, viz. “ ex¬ ceeding fmall bodies, exceeding fmall pores, and ex¬ ceeding fmall motions.” The firft muft either be the parts of larger bodies ; or things, the whole of which is exceedingly minute, fuch as fmall feeds, infeds, fands, falts, &c. The fecond are the interftices be¬ tween the folid parts of bodies, as in ftones, minerals, fhells, &c. or the mouths of minute veffels in vege¬ tables, the pores in the fkins, bones, &c. of animals, —Exceeding fmall motions' are the movements of the feveral parts or members of minute animals, or the motion of the fluids contained either in animal or ve¬ getable bodies. Many, as Mr Baker obferves, even of thofe who have purchafed microfcopes, are fo little acquainted with their general and extenfive ufefulnefs, and fo much at a lofs for objeds to examine by them, that, after di¬ verting themfelves and their friends fome few times with what they find in the Aiders bought with them, or two or three more common things, the microfcopes are laid afide as of little farther value; and a fuppo- fition that this muft be the cafe, prevents many others from buying them : whereas, among all the inven¬ tions that ever appeared in the world, none perhaps can be found fo conftantly capable of entertaining, improving, and fatisfying the mind of man. An examination of objeds, in order to difeover truth, requires a great deal of attention, care, and patience, together with .fome confiderable fkill and dexterity, (to be acquired by pradice chiefly), in the preparing, managing, and applying them to the mi¬ crofcope. When any objed comes to be examined, the fize, contexture, and nature of it, fhould be duely confidered, in order to apply it to fuch glaffes and in fuch a manner as may fhew it beft. The firft ftep towards this fhould conftantly be, to view it thro’ a magnifier that can take in the whole at once : for, by obferving how the parts lie as to one another, we fhall find it much eafier to examine and judge of them fe- parately if there be occafion. After having made ourfelves acquainted with the form of the whole, we may divide it as we pleafe ; and the fmaller the parts into which it is divided, the greater muft be the mag¬ nifiers with which we view them. The tranfparency or opacity of an objed muft alfa be regarded, and the glaffes made ufe of muft be fuit- ed to it accordingly : for a tranfpSrent objed will bear a much greater magnifier-than one that is opaque; fince the nearnefs required in a large magnifier un¬ avoidably darkens an opaque obj^d, and prevents its being feen, unlefs by the microfcope contrived on purpofe for fuch objeds. Moft objeds,. however, be¬ come tranfparent by being divided into extremely thin or minute parts. Contrivance therefore is requifiteta reduce them into fuch thinnefa or fmallnefs as may render them moft fit for examination. The nature of the objed, whether it be alive or dead, a folid or a fluid, an animal, a vegetable, or a mineral fubftance, muft likewife be confidered, and all the circumftances attended to, that we may apply it in the moft convenient manner. If it be a living ani¬ mal^ 550 OPT optical mal, care mu ft be taken to fqueeze, hurt, or dif- InftruinehtsCompofe it as little as pofiible, that its right form, po- ^fture, and temper, may be difcovered. If a fluid, and too thick, it muft be thinned with water ; if too thin, we muft let fome of its watery parts evaporate. Some fubftances are fitteft for obfervation when dry, others again when moiftened; fome when frefti, and fome af¬ ter being kept a while. Light is a thing next to be taken care of; for on this the.truth of all our examination depends, and a very little experience will {hew how differently objedts appear in one pofition and kind of it, from what they do in another. So that we (hould turn them every way, and view them in every degree of light, from bright- nefs even to obfcurity ; and in all pofitions to each degree ; till we are certain of their true form, and that we are not deceived. For, as Mr Hooke fays, it is very difficult, in many objefts, to diftinguifli be¬ tween a prominency and a depreffion, between a (ha- dow and a black ftain ; and, in colour, between a re¬ flection and a whitenefs. The eye of a fly, for in- ftance, in one kind of light, appears like a lattice drilled through with abundance of holes,; in the fun- fliine, like a furface covered with golden nails; in one pofition like a furface covered with pyramids, in ano¬ ther with cones, and in other pofitions of quite other fhapes. The degree of light muft be duly fuited to the objefl:: which if dark, will be belt feen in a full and ftrong light; but, if very tranfparent, the light {hould be proportionably weak ; for which reafon there is a contrivance both in the Angle and double microfcope to cut off abundance of its rays when fuch tranfparent objects are viewed by the greateft mag¬ nifiers. The light of a candle, for many objeCts, and efpecially fuch as are exceedingly minute and tranfpa¬ rent, is preferable to day-light. For others, day¬ light is beft; that is, the light of a bright cloud. As for fun-ftiine, it is reflected from objeCts with fo much glare, and exhibits fuch gaudy colours, that nothing can be determined by it with certainty ; and there¬ fore it is to be accounted the worft light that can be had. This opinion of foolhine, however, mull; not be extended to the folar microfcope, which cannot be ufed to advantage without its brighteft light: for in that way we fee not the objeCt itfelf, whereon the fun- fiiine is caft, but only the image or (hadow of it exhi¬ bited upon a fcreen ; and therefore no confufion can arife from the glaring reflection of the fun-beams from the objeCt to the eye, which is the cafe in other mi- crofcopes: but then, in this way, we muft reft contented with viewing the true form and ftiape of an objeCt without expeCting to find its natural colour, fince no {hadow can pofiibly wear the colours of the body it reprefents. Moft objeCts require fome management in order to bring them properly before the glaffes. If they are flat and tranfparent, and fuch as will not be inju¬ red by preffure, the beft method is to inclofe them in Aiders, between two Mufcovy talcs or ifinglafs. This way, the feathers of butterflies, the fcales of fiflies, the farinae of flowers, &c. the feveral parts aad even whole bodies of minute infeCts, and a ICS. Partin. thoufand other things, may very conveniently be pre- Qpticali ferved. Every curious obferver, therefore, will haveIn^ruwY them always ready to receive any accidental objeCt, T and fecure it for future examination : and a dozen or if two of thefe fliders properly furniflied are 8 fine natu- | ral hiftory. In making a collection of objeCts, the fliders | {hould not be filled promifcuoufly, but care taken to fort the objeCts accordingto their fize and tranfparen- | cy ; in fuch a manner that none may be put together | in the fame Aider but what may be properly examin¬ ed by the fame magnifier : and then the Aider fliould I be marked with the number of the magnifier its objeCts are fitteft for: that is, the moft tranfparent, or mi¬ nuted objeCts of all, which require the firft magnifier to view them by, fiiould be placed in a Aider or Aiders marked with number I, thofe of the next degree in fliders marked with number II, and fo of the reft. j| This method will fave abundance of time and trouble in (hifting the magnifiers, which, without fuch forf- ment, muft perhaps be done two or three times, in overlooking a Angle Aider. The numbers marked out I upon the Aiders will likewife prevent our being at any t] lofs what glafs to apply to each. In placing your § objeCts in fliders, a convex glafs of about an inch focus, to hold in the hand, and thereby adjuft them properly between the talcs, before you fallen them down with the brafs rings, will be found very conve- | nient. Small living objeCts, fuch as lice, fleas, gnats, ij; fmall bugs, minute fpiders, mites, &c. may be placed between thefe talcs, without killing or hurting them, if care be taken not to prefs down the brafs rings that keep in the talcs, and will remain alive even for | weeks in this manner. But if they are larger than | to be treated thus, either put them in a Aider with concave glaffes intended for that ufe, or in the cell de- 1 fcribed above, or elfe examine them ftuck on the pin or held between the plyers; either of which ways they may be viewed at pleafure. If fluids come under examination, to difcover the animalcules that may be in them, take up a fmall drop | with your pen or hair-pencil, and place it on a Angle j ifinglafs, which you rtiould have in a Aider ready, or elfe in one of the little concave glaffes, and fo apply j it. But in cafe, upon viewing it, you find, as often happens, the animalcules fwarming together, and fo ] exceedingly numerous, that, running continually over one another, their kinds and real form cannot be ! known ; fome part of the drop muft be taken off the glafs, and then a little fair water added to the reft, will make them feparate, and fhew them diftinft and well. And this mixture of water is particularly neceffary in viewing the femen mafculinum of all creatures ; for the animalcules therein contained are inconceivably minute, and yet crowded together in fuch infinite num¬ bers, that, unlefs it be diluted a great deal, they can¬ not be fufficiently feparated to diftinguifh their true fhape. But if we vie'w a fluid, to find what falls it may have in it, a method quite contrary to the foregoing muft be employed: for then the fluid muft be fuffered to evaporate, that the falls, being left behind upon the glafs, may the more eafily be examined. Another, and indeed the moft curious way of ex¬ amining PartlH. OPT I| Optical amining fluids, is by applying them to the microfcope tjnftrumems exceedingly fmall capillary tubes made of the thin- neft glafs poffible. This was Mr Leeuwenhoek’s me¬ thod of difcovering the fttapes of falls floating in vinegar, wine, and feveral other liquors; and fuch tubes Ihould be always ready to ufe as occafion requires. For the circulation of the blood, frogs, newts, or fifhes, are commonly made ufe of; and there are glafs tubes in the Angle microfcope, and a filh-pan as well as tubes in the double one, on purpofe to con¬ fine thefe creatures, and bring the proper parts of them to view : thefe parts, in newts and fifhes, are the tails, and in frogs the fine filmy membrane between the toes of the hinder legs. Though, if we can con¬ trive to fallen down the creature, and bring our ob- Ijedt to the magnifier, the circulation cannot poffiblybe feen fo plainly any where as in the mefentery, or thin' tranfparent membrane which joins the guts together; and this part, by pulling out the gut a little, may ea- fily be adjufted to the magnifier. To difieft minute infe£ts, as fleas, lice, gnats, mites, &c. and view their internal parts, requires a great deal of patience and dexterity; yet this may be done in a very fatisfa&ory manner, by means of a fine lancet and needle, if they are placed in a drop of wa¬ ter : for their parts will then be feparated with cafe, and lie fair before the microfcope, fo that the ftomach and other bowels may be plainly diftinguifhed and ex¬ amined. We fhould always have ready for this purpofe, little flips of glafs, about the fize of a Aider, to place objefls on occafionally ; fome of which flips fhould be made of green, blue, and other coloured glafs, many objedls being much more diftinguifhable when placed on one colour than on another. We fhould likewife be provided with glafs tubes of all fixes, from thefinefl capillaries that can be blown, to a bore of half an inch diameter. There is, perhaps, no better way of preferring tranfparent obje&s in general, than by placing them between clear ifinglafs in Aiders: but opaque bodies, fuch as fands, feeds, woods, &c. require different ma¬ nagement, and a colledion of them fhould be prepared in the following manner. Cut cards into fmall flips, about half an inch in length, and one tenth of an inch in breadth : wet them half their length with a ftrong but very tranfpa¬ rent gum-water, and with that flick on your objedd. As the fpots of cards are red and black, by making your flips of fuch fpots, you will obtain a contrail to objefts of almoft any colour ; and by fixing black things on the white, white on the black, blue cr green on the red or white, and all other coloured obje&s on flips moft contrary to themfelves, they will be fhewn to the bed advantage. Thefe flips are intended chiefly for the microfcope for opaque objeds, to be applied between the nippers: but they will alfo be proper for any other microfcope that.can fhew opaque bodies- A little fquare box fhould be contrived to keep thefe flips in, with a number of very fhallow holes in it jufl big enough to hold them. If fueh holes were cut through that pafteboard of which the covers of books are made, exaftly fitted to the box, and a paper pafted on one fide of it to ferve for a bottom to it, three or four fuch paflvboards flored with objects might lie up¬ on one another in fame box, and contain too or more ICS. 5507 flips; with obje&s fattened on them, always ready for Optica| examination. It will not be found amifs to provide Intbumeurs fome flips larger than others, for the reception of dif¬ ferent fixed obje&s. But this will, perhaps, be bet¬ ter underftood by an infpeftion of fig. 3. The box fhould likewife be furnifhed with a pair of pliers, toPI3'6 take up and adjufl the flips, and therefore a convenientCCXXI1, place is contrived therein to hold them, as is ihewn in the figure. There is no advantage in examining any ohjefl with a greater magnifier than what fhews the fame di- flindly ; and therefore, if you can fee it well with the third or fourth glafs, never ufe the firfl or fecond; for the lefs a glafs magnifies, the better light you will have, the eafier you can manage the objedt, and the clearer it will appear. It is much to be doubted, whe¬ ther the true colours of objedts can be judged of when feen through the greateft magnifiers: for as the pores or interftices of an objedt mull be enlarged according to the magnifying power of the glafs made ufe of, and the component particles of matter mutt by the fame means appear feparated many thoufands of times farther than they do to the naked eye, their reflexions of the rays of light will probably be different, and ex¬ hibit different colours. And indeed the variety of co¬ louring which fome objedls appear dreffed in, may ferve as a proof of this. The motions of living creatures themfelves, or of the fluids contained within them, as feen through the roicrofcope, are Hkewife not to be determined without due confideration : for, as the moving body, and the fpace wherein it moves, are magnified, the motion mutt probably be fo too; and therefore that rapi¬ dity wherewith the blood feems to pafs along through the veffels of fmall animals mutt be judged of accord- ingly. § 15. Doll-jncTs Achromatic Telefcope. Mr. Doliond’s telefcopes are of two kinds. I. Thofe in which only the eye-piece Aides, fo as to be drawn out as far as is neceffary for procuring diilinft vifion. Of this form are all the larger inflruments; which are therefore generally fixed upon a Hand, for viewing objedls with greater (leadinefs.—2. Thofe which are compofed of feveral Aiding tubes, for the convenience of being put into the pocket. The ufual method of makingthe Aiding tubes of tele* fcopes has been with paper covered with vellum ; but as fuch tubes have been found liable to feveral inconve- niencies from being affedled by the moillure of the air, they are now contrived to be made exceedingly thin of brafs, and the outfide of mahogany. The Aiding tubes are all made to flop, when drawn out to the proper length; fo that, by applying one hand to the outfide tube A, fig. 4. and the other hand to the end of the fmallell tube B, the telefcope may be, at one pull, drawn out to its whole length, as is re- prefented by fig. 5.; then any of the tubes may be flip¬ ped in a little while you look through, and the objedt rendered diftindt to any fight. To make the tubes Aide properly, they all pafs thro* ftiort fprings or tubes, which are fetewed in at a,ht and c, fig. 5. Thefe fprings may be unferewed from the ends of the Aiding tubes by means of the milled edges which projedt above the tubes, and the tubes taken from one another when required. There 559§ OPT Optical There are four convex Cye-glafles to thefe tele- Inftriiitientsfcopes, whofe furfaces and focal-lengths are fo pro- ~ portioned as to render the field of view very large.— Thefe eye-glafles are all contained in the fmallelt Aiding tube ; three of them may be feen by unfcrew- ing the tube at e e e; and the fourth, which is at the end of the tube, may be come at by unfcrewing the fpring at c. Thefe telefcopes are of three different lengths and fixes, ufually called i foot, 2 feet, and 3 feet. 14 Inches. 28 ditto. 40 ditto. Length when Ann up. 5 Inches. 9 ditto. 10 ditto. Aperture of the Achromatic Obje£t-glafs. I,i Inches. 1,6 ditto. 2,0 ditto. Wei^t. 6 Ounces. 16 ditto. 30 ditto. The bed achromatic telefcopes which Mr Dollond has yet made, are thofe with a triple objeft-glafs of about 45 inches focal diftance, with an aperture of 34- inches. Some of thefe magnify the diameters of objedls 150 times, with great diftin&nefs, and light fufficient for moft aftronomical purpofes. When fitted (for terre- ftrial objedls) with an eye-piece magnifying about 70 or 80 times, they give moft agreeable vifion. The objed-glafs of one' of thefe telefcopes was found to have the following radii (in inches) of cur¬ vature for its different furfaces, beginning with that next the objedf, 264, 374, ty-rV, 264, 26-f-, 26-4. But it does not appear that Mr Dollond and the bed ar- tids abide by a fixed rule in their condruflions ; for telefcopes of the fame length and magnifying power, and made by the fame artid, have different conftruc- tions of the objeft glafs. This may be expedled, when wre confider the variable nature of the flint-glafs. It is probable, that thete very fine objedi>glaffes have been produced by trials pro re nata of different curva¬ tures. Till fome method can be difcovered of making flint glafs free from veins, which differ in their refrac- iing power, it is not probable that larger tele¬ fcopes than thofe now mentioned will be produced. § \6. Of the Newtonian Re fie fling Telefcope. Flafe Fig. 1. fhews one of thofe telefcopes made by the CCXXin. jjon> Samuel Molyneux, and prefented by him to king John V. of Portugal. ABC reprefents a tri¬ angular board or table fupported by the globe D, and by the annexed carvings and malks, and which ferves for the bafis or pededal of the indrument. Upon occafion this board may be taken off by un¬ fcrewing three iron fcrews, the heads of which lie near the three volutes at the three corners. At E is repre- fented a fmall key or handle which turns fome wheel- work, concealed under the board of the table, and which ferves to give an horizontal circular motion to the pillar F placed in the middle, and to the fuperincumbent tube HIKE. If this fhould ever be out of order by taking off the upper board, it may be re&ified. At G is reprefented another handle which gives the tube its perpendicular motion ; fo that while the obferver fits with his right fide applied to the fide of the table AC at the end C, by turning the two handles E and G, he can give the tube any required elevation or azimuth, and thereby follow the motion of the heavenly bodies very commodioufly. ICS. Partin: The telefcope itfelf confifts of two metalline fpecula Optical and an eye-glafs, which are to be duely placed in the Inftnimel tube HIKE left open at the end HE. The large concave fpherical fpeculnm ik is to be placed within the tube at IK; in which are fixed three flops, or bits of wood, againft which the polifhed furface of the < fpeculum being applied, the axis of refledlion will fall ; exaftly in the axis of the tube. In the brafs plate which clofes this end of the tube, there are three fcrews intended for holding the metal in this fituation; l but many cautions are requifite with regard to this metal and the placing of it. In the firft place, it is i never to be touched, but by fcrewing into the backfide ] of it a handle /, which fits the hole therein. In the next \ place, great care mufl be taken not to breathe on it, or to expofe it to damp air. If any thing of that kind happens, it muft be wiped thoroughly dry with a linen cloth before a fire; and it may be fometimes in like ' manner cleaned with a rag wetted in fpirit of wine ; provided the fpirit be not left to evaporate, for that would leave an humid fediment which wouldEurt the polifh. In the third place, unlefs when in ufe, it fhould be conftantly kept with its face downwards on a piece of plane glafs made on purpofe. The fpeculum is a portion of a concave fphere whofe diameter is about eight feet eight inches, and |! which of confequence colle&s the rays into a focus about 26 inches diftant from its furface. The laws of | refleftion are fuch, that any error in the figure ef this 1 fpeculum will produce about fix times as great an ir¬ regularity in the pi&ure formed in'its focus, as the like irregularity would caufe in a common refra&ing tele¬ fcope. It hath been found by experiment, that an error of lefs than 1000th part of an inch is capable of vitiating its figure ; fo that great care muft be taken in placing the metal in the tube for ufe, againft the three flops above-mentioned; and that the three fcrews at IK be gently ferewed, only j'uft fufficient to bear the metal truly againft the flops; for the fmalieft excefs of ftrefs in the fcrews againft the back of the metal may diftort and very much damage its figure. There is alfo a piece of wood >n, having a round hole p in it, and carrying a fmall brafs arm «, which holds the other fmaller fpeculum o, which is plane. This fpe¬ culum muft be always preferved from the air when out of ufe. When the telefcope is to be ufed, the cqver ^ of the fmall fpeculum muft firft be taken off; then ^ « place it in the tube at the hole M, which exactly fits the above-faid fquare piece. Prefs it in pretty tight and true ; which, if duely performed, the centre of the fmall fpeculum will be placed in the axis of the large concave one, and will reflect the parallel rays which enter at the open end HE, to the round hole/* in the faid fquare piece, -ro which hole one of the two eye-glaffes in its cel! ^ is to be placed; and then the inftrument is prepared for ufe. The obferver is there¬ fore to place himfelf at the fide of the tube, and to look in at M, where he will fee the images of the ob¬ jects which lie at his left-hand. In taking out or put¬ ting in the little fpeculum at c, great care muft be ufed to avoid (baking or bending the arm ; for the fmalleft accident of that kind will certainly diforder its fituation. There are three fcrews at the back, the middlemoft of which fixes it to the arm mn; the other two only prefs upon the back, and lerve to ad- juft Part III. OPT Optical juft its fituation to an exa& angle of 450 with the fn{tinmentsax;3 0f great fpeculum. There are two eye-glafles, whereof the one that hath the largeft aperture being made ufe of, th einftrument will magnify as much as a common refrafting tclefcope of about 20 or 22 feet long; and with the eye-glafs that hath the fmalleft apertures, it will magnify as much and as diftiri&ly as one of 3£ or 40 feet. At P Hands a round button of ivory ; and at Qjs reprefented a fmall pin of ivory, which may be feen with a fmall white thread fixed to it, at the end of the tube H. This thread at the other end is fixed in the infide of the tube ; and towards the middle of it, itis wound once roundthe inward endofthe ivory button P. From this difpofition, by turning round the ivory button P, the whole Aider of black ebony wood NO, ' with the fmall fpeculum and the eye-glafs applied at M, may be made to approach to or recede from the large fpeculum at the other end IK: and by this means its true diftance, and the diftinft appearance of the objeft, muft be found, for various diftanccs of ‘ the fame objeff, and for the various eyes of different obfervers; which variety in different perfons, from the great magnifying power of the eye-glafs in this inftrument, will be confiderably more fenlible than in a refra&ing telefcope. But the true diftance of the fpecula will immediately be found in all cafes, by turning this ivory pin P backwards and forwards very floWly and gently; and, for celeftial objedls, the true diftance being once found for the obferver’s eye, a fmall mark may be made acrofs the Aider, and upon the edge of the tube, to bring it fpeedily, and without any difficulty, to its proper place at another time. By the little ivory pin at the firing may be tightened or relaxed to make the Aider NO move moft eafily as occafion requires. Either of the eye-glaffes being ap¬ plied in the cylindrical hole />, in the fquare piece inp, may alfo be made to approach to or recede from the focus, by turning round the fmall tube q in which they are inferted, the outfide whereof is wrought into a fine ferew for that pnrpofe. Diftindt vifion may alfo by that means be obtained for different eyes, without moving the whole Aider NO. RS reprefents a fmall refrafting telefcope, whofe axis is parallel to the axis of the refle&or. In its focus there are placed two crofs-hairs, and its only ufe is to find out any objeft more readily by the refle&or. The eye being applied at S, turn the two handles at E and G, till the point of the objed to be viewed in the refleftor falls exactly on the crofs-hairs ; then the eye applied at'M to the refledor, will fee the fame objed diftindly; with this caution, that as the whole inftru¬ ment with its bafis can eafily be moved, the moft con¬ venient fituation for the obferver will be to keep the tube HI nearly at right angles to the fide AC, and to fit with the fide AC flat againlt his right fide near C, as hath been already mentioned. And in finding the objed at firft with the fmall refrading telefcope, it is moft con¬ venient to ftand at the corner of the table C. The handle G, may be inferted at either fide of the pillar F, as con¬ venience (hall require. At the (mail pillars TV, which fupport and hold the fmall telefcope RS, there arefome fmall ferews near T, which being relaxed, the direc¬ tion of the tube RS way be altered horizontally by pufliing the tube with the hand fidewife, either way, as occafion requires, and then tightening the (crews Vot..

And at V there sre ferews and a fpringing Optical piece of brafs, which, beiag relaxed or tightened, willInf,rumcn^ in like manner alter its elevation, fo as to reftore the parallelifm of the tubes in cafe of any accident that may have difturbed them. In making obfervations, it will be found convenient not to touch the table, but only to move the handles, as the motions of the (far or other celeftial body dired ; for in an inftrumtnt that magnifies fo much, the leaft motion or trembling is magnified proportionably. In this telefcope Dr Smith takes notice of a re¬ markable deception; namely, that, when the refledor is compared with a refrading telefcope of equal mag¬ nifying power, the obferver always imagines that the latter has the advantage. For this he does not pre¬ tend to account, but looks upon it to be an optical deception common to all mankind. § 17. The Gregorian Re fie fling Telefcope. This is reprefented, fig. 16.

On the top of this ftand is faftened the plate CD, having in it a focket to receive the brafs ball D. This plate is compofed of two parts; and by means of the ferews L, M, the focket is tightened or loofened on the ball, fo that it can ei¬ ther allow it a free motion, or keep it firm in its place. This ball is fully ffiewn at fig. 17.; and, with its ftalk F, is ftddered into the piece of brafs FG, which is again faftened on the body of the telefcope by means of the ferews HI. The whole length of the telefcope is reprefented by ah; the eye-piece, or the part wdiich contains the eye-glaffes, by a r; the other part, con- # taining the fpecula, is reprefented by cb. Fig. 4. and 5. fhew the proportional fuse of the two fpecula to one another. The larger is placed at c, in the fame man¬ ner and with the fame precautions as have been al¬ ready mentioned with regard to the Newtonian tele¬ fcope; the other is placed on a fhort arm within the tube, in fuch a manner, that it occupies exaftly the middle of it: and by means of a rod rpqmo, having the upper end of it turned into a ferew, the little fpe¬ culum can be removed from the other, or brought nearer to it, as occafion requires. In the eye-piece, ar, are two eye-glaffes, which receive the light re- flefted from the little fpeculum ; and the eye being applied at a, the obferver fees thofe objeCls which are placed direftly before the mouth of the tube. The following are the proportions of an excellent Gregorian telefcope, made by Mr James Short of Edinburgh, which may ferve as a model for calcula¬ ting others of any given length. inches.

For finding the magnifying power of a telefcope by experiment, Dr Smith tells us, that the following method was purfued by Mr Haukfbee, Mr Folkes, and Dr Jurin. Having fixed a paper circle of one inch diameter upon a wall, at the dittance of 2674 inches from the eye-glafs of the telefcope, they viewed it in the telefcope with one eye, while, with the other eye naked, they viewed two parallel lines drawn upon paper, 12 inches afunder, moving them gradually to and fro, till they appeared to touch two oppofite points of the circle feen in the telefcope; and then the perpendicular diftance of the lines was found to be 332 inches. In this pofition of the objefts, the angle at the eye made by the rays that came from the ex¬ tremities of the diameter of the one-inch circle, was equal to the angle fubtended at the other eye by the 12-inch interval of the parallel lines; and therefore the ratio of this angle to that which the faid circle would fubtend at the naked eye, viewing it at the faid diftance of 2674 inches, is the magnifying power of the telefcope; and is compounded of the diredl ratio of the fubtenfes of thefe angles, and the inverfe ratio of the diftances of the fubtenfes from the eye; that is, of 12 to 1, and of 267410 142: which make the ratio of 226 to 1, very nearly. Suppofing a larger paper circle had been placed at lb great a diftance, that its pi&ure might have been formed by the fpeculum in its principal focus; the telefcope would have magnified it more than our one- inch circle, in the ratio of the diftance of this latter fc circle from the principal focus, to its diftance from the centre of the fphere of the fpeculum: becaufe the diameter of the picture of the remoter circle would have been greater, in this ratio, than that of the one- inch circle, fuppofing thefe circles to fubtend the fame angle at the centre of the fpeculum. But this ratio, in the prefent experiment, being only 2674 to 2671, gives only an inconfiderable incrcafe to the magnifying power already determined. Thus we have an eafy and accurate method of exa¬ mining the goodnefs of a telefcope of any kind. Firft, by giving it the lead eye-glafs that will fhew the new moon, or rather Jupiter and Saturn, with fufficient light and diftinftnefs when the air is quiet and pure; and then by finding how much it magnifies by the method abovementioned. But if feveral telefcopes of the fame kind have nearly the fame length, thofe are the beft in their kind with which you can read a print at the greateft diftance. That the reader may have fome notion of the powers of telefcopes in this way, we (hall fubjoin a ftiort account of the effefls of fome refle&ors made by Mr James Short of Edinburgh, as related by Mr Maclaurin. With a reflefting telefcope, of which the fpeculum was quick-filvered glafs, and focal diftance 15 inches, the Philofophical Tranfa&ions could eafily be read at the diftance of 230 feet; by another of. the fame di- menfions, the Tranfa&ions could be read at 280 feet diftance. By a telefcope of the fame kind, whofe focal diftance was nine inches, Mr Maclaurin read in theTranfaffions at the diftance of 138 feet; and ano¬ ther much fmaller print at the diftance of 1,25 feet. I C S. Partin. It is not mentioned whether thefe telefcopes were of Optical the Newtonian or Gregorian form; though it is moftIn^rumenls probable that they were of the former kind. As the light produced by thefe glafs fpeculums was very faint, Mr Short next applied himfelf to the con- ftru&ion of metallic ones, and the effe&s of thefe were vaftly greater; but as they were of the Grego¬ rian form, it is'doubtful whether we are to aferibe their fuperiority entirely to the ufe of metalline fpe¬ culums, or to the more advantageous conftru&ion of them. Thefe telefcopes had focal diftances of two inches and 6-ioths; of four inches; fix, nine* and 15 inches. By thofe of four inches, the fatellites of Ju¬ piter were feen very dittin&ly; and he could read the Philofophical Tranfa&ions at above 125 feet diftance. By thofe of fix inches focus, he read at 160feet diftance; by thofe of 9 inches, he read at 220 feet diftanec; and by thofe of 15 inches,he was able to read the Tranfadions at 500 feet diftance. With thefe laft he alfo feveral times faw the five fatellites of Saturn. The effe&s of thefe 15-inch telefcopes of Mr Short’s therefore were equal to thofe of the beft x7-feet refra&ors ever known; for it was thought wonderful that Caffini ftiould obferve all the fatellites of Saturn with a 17-feet refrading telefcope. $ 18. 77;s reprefented at A ; it (lands upon leexxv. ^eet ^iat have rollers joined to them, that it may be ;fig. j. eafily moved. It is open at one end, which end is mo¬ ved to a window, through which the fun’s rays come freely to the fpeculum. “ But the box is every way larger than the win¬ dow, that, by being applied clofe to the wall, the light may be hindered from entering into the chamber; to this end, the box is moved as near the wall as pofiible, and the ferews C, C, which are fattened to the fore¬ feet, are turned till they touch the ground. “ The door in my machine is oppofite to the win¬ dow ; it might have been otherwife difpofed. We tranfmit the rays through the fore part B ; we make choice of this, by reafon of the make of the place in which the experiments concerning light were made. In this part there are two apertures three inches broad, and about to inches high, one of which is reprefented open at DE. “ Thefe are clofed on the outfide by pieces of wood, which are moveable between wooden rulers. Each piece ferves either aperture, that they may be changed. One of them F is three feet long, and has a hole in its middle. The aperture is five inches long, and two broad. “ This is clofed by the copper plate GH, in which there are two holes, c, d; the diameter of that is two thirds of an inch, the diameter of this is lefs. Thefe holes are (lopped by the plates I and K, which are applied to the firit plate GH, and are moveable about the centres i and k : the magnitudes of the holes may alfo be varied, by turning the laft plates, as the fi¬ gure (hews. “ The board F is hollowed behind, in order to receive the objedl-glafs of a telefcope of 16, 20 or 25 feet, according to the magnitude of the place in which the experiments art made ; the centre of this glafs ought to anfwer to the centre of the hole c. “ This board F is pretty long ; the holes of the fmall plate may anfwer to any part of the aperture of the box, the other part of the aperture remaining (hut. ICS. 5603 For this reafon the fecond board is fhorter; it is fuffi- Optical cient if the aperture be clofed with this. Thefe boardsInftruments are fattened by the ferews M, M. “ We have (hewn how the box is to be applied to the window ; but this cannot be done thus, if we would make the experiments in the hours in which the fun’s rays enter the window very obliquely. In this cafe, that the rays may come to the fpectr- lum, the box muft anfwer to a part of the window only ; the remaining part is clofed any other way : I make ufe of a curtain to exclude all the fun’s rays.” § 20. Equatorial Telefcopet or Portable Obfervatory. The Equatorial Telefcope was contrived by Mr James Short; and confifts of two circular planes or plates A A, fupported upon four pillars; and thefe again fupported by a crofs-foot or pedeftal moveable at each end by the four ferews BBBB. The two circular plates AA> are moveable, the one above the other, and called the horizontal plates, as reprefenting the horizon of the place ; and upon the upper one are placed two fpirit-levels, tn render them at all times horizontal: thefe levels are fixed at right angles to each other. The upper plate is moved by a handle G which is called \\\e horizontal handle, and is divided into 360°, and has a nonius index divided into every three minutes.—Above this horizontal plate is a femicircle DD; divided into twice 90°, which is called the meridian fetnicircle, as reprefenting the meridian of the place; and is moved by a handle E, called the meridian handle', and has a nonius index divided into every three minutes. Above this meridian femicircle is fattened a circular plate, upon which are placed two other circular plates FF, moveable the one upon the other, and which are called the equatorial plates ; one of them, reprefenting the plane of the equator, is divided into twice twelve hours, and thefe fubdivided into every ten minutes of time. This plane is moved by a handle G, called the equatorial handle, and has a nonius index for (hew¬ ing every minute. Above this equatorial plate there is a femicircle HH, which is called the declination femi¬ circle, as reprefenting the half of a circle of declina¬ tion, or horary circle, and is divided into twice 90°, being moved by the handle K, which is called the declination handle. It has alfo a nonius index, for fubdividing into every three minutes. Above this de¬ clination femicircle is fattened a reflefting telefcope LL, the focal length of its great fpeculum being 18 inches. In order to adjuft this inftrument f ancj the difficulty in well replacing it ver¬ tically again, hinders our making obfervations oftener than once in four minutes, during which time the dif¬ ference in the ftar’s altitude will be one degree. In thefe cafes, therefore, it will be better to have the true pofition of the meridian, In order to place the in¬ ftrument exaftly in it; or to move it fo that one may obferve the altitude of the ftar the moment it paffes the meridian. The refrafifion maybe found in the following man¬ ner. Having the meridian altitudes, and the declina¬ tion of two ftars of nearly equal altitudes, find a!fo,by the dire&ions already given, the apparent meridian al¬ titude of fome ftar near the pole ; and if the comple¬ ment of that ftar’s declination be added thereto or taken therefrom, we (hall have the apparent- height of the pole. After the fame manner may the apparent height of the equator be found by means of the meri- jdian altitude of fome ftar near it, and adding or fub- tradling its declination. Then thefe heights of the pole and equator being added together, they will al¬ ways make more than 90 degrees, becaufe both of them are raifed by the refra&ion : but taking 90 de¬ grees from this fum, the remainder will be double the refra&ion of either of the ftars obferved at the fame height; and therefore taking this refradtion from the apparent height of the pole, or equator, we (hall have their true altitude. To illuftrate this : Suppofe the meridian altitude of a ftar obferved below the north pole to be 30* 15', and complement of its declination 50 ; whence the appa¬ rent height of the pole will be 350 15'. Alfo let the apparent meridian altitude of fome other ftar, obfer¬ ved near the equator, be 30® 40', and its declination 40° 9'? whence the apparent height of the equator will be 54° 49’. Therefore the fum of the heights of the pole and equator thus found will be 90° 4'; from which fubtrafiing 90°, there remain 4', which is double the refraction at 30® 28' of altitude, which is about the middle of the heights found. Therefore at the al¬ titude of 30° 15', the refradion will be fomewhat above 2', viz. 2' t" ; and at the altitude of 30° 40', the refradion will be I’jfp". Laftly, if 2' 1" be taken from the apparent height of the pole, 35' 15", the re¬ mainder 35° 12' 59" will be the true height of the pole ; and fo the true height of the equator will be 54° 47' 1", as being the complement of height of the pole to 90°. The refraftion and height of the pole found according to this way, will be fo much the more exad as the height of the ftars is greater; for if the difference of the altitudes of the ftars (hould be even 2° when their altitudes are above 30°, we may by this method have the refradion and the true height of the pole ; becaufe, in this cafe, the difference of refrac¬ tion in altitudes differing only two degrees is not per¬ ceptible. The quantity of refradion may alfo be found by the obfervation of one ftar only, whafe meridian alti¬ tude is 90°, or a little lefs: for the height of the pole or equator above the place of obfervation being other- wife known, we (hall have the ftar’s true declination by its meridian altitude ; becaufe refradions near the zenith are infenfible. Now, if we obferve by a pen¬ dulum the exad times when the faidttar comes to every I C S. Part ill: degree of altitude, as alfo the time of its pafTage by Opticjt; the meridian, which may be known by the equal alti- Inftrl'rnf! tudes of the ftar being eaft and weft, the refradion may be found by the folution of a cafe in fpherical | trigonometry: for here, in a fpherical triangle, we have the diftance between the pole and zenith, the y complement of the ftar’s declination, and the angle comprehended by the arcs abovementioned ; namely, the difference of mean time between the paffage of the i ftar by the meridian and its place, converted into de- |l grees and minutes, to which muft be added the pro- i per proportional part of the mean motion of the fun in i the proportion of 59' S" per day ; therefore the true arc of the vertical circle between the zenith and true x |; place of the ftar may be had. But the apparent arc of the altitude of the ftar is had by obfervation, and the difference of thefe arcs will be the quantity of re- | fradion at the height of the ftar. To find the time of the equinox and folftice by ob- | fervation, we muft proceed in the following manner. I Having found the height of the equator, the refrac- I| tion, and the fun’s parallax at the fame altitude, it t1 will not be difficult afterwards to find the time in which the centre of the fun is in the equator; for if, from the apparent meridian altitude of the fun’s centre the I fame day that it comes to the equinox, be taken the convenient refradion, and then the parallax be added j thereto, the true meridian altitude of the fun’s centre | will then be had. Now the difference of this altitude ; and the height of the equinodial will (hew the true time of the true equinox before or after noon : and if the fum of the feconds of that difference be divided by 59, the quotient will (hew the hours and fradions . which muft be added to or fubtraded from the true hour i of noon to have the time of the true equinox. The hours of the quotient muft be added to the time of ; noon, if the meridian altitude of the fun be lefs than the height of the equator about the time of the vernal equinox ; but they muft be fubtraded, if it be found 1 greater. We muft proceed in a contrary manner when the fun is near the autumnal equinox. The folftices are found with much more difficulty ; for one obfervation only is not fufficient, becaufe about this time the difference between the meridian al- j titudes in one day and the next fucceeding day is al- ' moft infenfible. The exad meridian altitude of the fun muft therefore be taken for 12 or 15 days before ! the folftice, and as many after, that fo one may find the fame meridian angle by little and little ; to the end that, by the proportional parts of the alteration of the fun’s meridian altitude, we may the more exadly find the time when the fun’s altitude is the fame before and after the folftice, being in the fame parallel to the equator. Now, having found the time elapfed between both fituations of the fun, you muft take half of it, and feek in the tables the true place of the fun at thefe three times. This being done, the difference of the ex¬ treme place of the fun muft be added to the mean place, in order to have it with comparifon to the extremes; but if the mean place found by calculation does not agree with the mean place found by comparifon, you muft take the difference, and add to the mean time, that which anfwers to that difference, if the mean time found by calculation be leffer; but, if greater, it muft be fubtraded, in order to have the time of the fol¬ ftice. - ' (o') St!

Here It mud be noticed, that an error of a Inftruments few fecon(js Jn the obferved altitude of the fun will make an alteration of an hour in the true time of the folftice ; whence it is plain, than the true time of the folftice cannot be had but with inftruments very well divided, and feveral very exaft obfervations. With regard to eclipfes, the beginning, end, and total emerfion may be eftimated with fufficient exaft- nefs without telefcopes; excepting the beginning and ending of lunar eclipfes, where an error of one or two minutes may be made, becaufe it is difficult to deter¬ mine with certainty the extremity ofthe lhadow. But the quantity of the eclipfe, that is, the eclipfed por¬ tion of the fun and moon’s dilk, which is meafured by digits, or the 12th part of the fun and moon’s diame¬ ter, and minutes, or the 60th part of digits, cannot be well known without a telefcope joined to fome in- ftrument. One method of obferving them by the fo- lar telefcope hath been already defcribed ; but this ap¬ plies only to eclipfes of the fun, thofe of the moon not being difcoverable by reafon of the faintnefs of the light: for thefe therefore micrometers mult be ufed, which are be placed in the focus of the telefcope, Bnd of which various kinds are defcribed under the ar¬ ticle Micrometer. The eclipfes of the fateliites of Jupiter are to be obferved in the fame manner, but re¬ quire a better telefcope than what is neceffary for ob¬ ferving the eclipfes of our moon. It is here proper to take notice of the method of obviating a difficulty formerly taken notice of j name¬ ly, that in a ferene night we often find the light of Jupiter and its fateliites obferved through the tele¬ fcope to diminifh by degrees, fo that it is impoffible to determine exattly the true times of the immerfion and emerfion of the fateliites. This proceeds from the dew which falls upon the furface of the objeft-glafs, and intercepts the light. A very hire remedy is, to make a tube of blotting paper, about two feet long, and of a fufficient bigncfs to go about the end of the tube of the telefcope next to the objeft-glafs, which will very efFeftually drink up the dew, and hinder it from coming to the objed-glafs; and by this means we may make our obfervations with fufficient exadlnefs. $ 15. Telefcopic Injlruments for finding ’Time by obfer¬ ving ’when the Sun or any Star has equal Altitudes on tgj each fide of the Meridian. in ft rumen* ^NE t^ie^e *n^ruments W3S made by Mr Roger defcribed. Cotes, and was contrived by him for the purpofe of regu¬ lating a pendulum-clock prefented to the Royal Society by Sir Ifaac Newton, to whom he fent the following Plate defcription. “ AB is a ftrong wooden axis about fix CCXX7f. feet in length : CD and DE on one fide, EF and FG *• on the other, are pieces framed to each other and to the axis as firmly as was poffible. Into the piece CD, and at the angle F, were fixed ftrong wooden pins nearly parallel to each other, and perpendicular to the plane CDEFG. PQ_is the cylindrical brafs tube of a five-foot telefcope (belonging to our fextant;) this was well fattened with iron ftaples and fcrews to the piece of wood IKML, whofe under plane furface is here reprefented as obje&ed to view. Into this fur¬ face there was perpendicularly fixed a ftrong wooden pin N, which was defigned to hang the upper end of Von. VIII. 2 ICS. 5607 the telefcope upon any of the pins in CD, whilft its Optical lower end retted upon the pin F. Now, that the tele-InftTument!’ fcope might be taken off, and yet afterwards be again r~~ placed accurately in the fame pofition, I ordered the edges IK and CD, which touched each other, to be rounded like the furface of a cylinder, as alfo the edge EF into which the pin F was fixed, and againft which the cylindrical tube of the telefcope refted, fo that the contaft in both places might be made in a point. Up¬ on the fame account the pins in CD were made a little hollow, as is reprefented at R ; and the pin F was a fruftum of a cone, that thereby the telefcope might more furely touch the edges CD and EF. Into the two ends of the wooden axis were ftrongly fixed two pieces of well-tempered fteel: that at the upper end A was a cylinder well turned, which moved in a collar, whofe cavity, reprefented by S, was figured like two hollow and inverted fruftums of cones joined together ; the lower at B was a cone moving in a conical focket of a fomewhat larger angle. This focket had liberty to be moved horizontally, and to be fixed in any pofition by two fcrews, which preffed againft it fideways at right angles to each other. The inftrument being thus pre¬ pared, 1 fixed a needle V, at the lower end of the wooden axis, whofe point flood out from it about an inch; then fufpending a fine plumb-line TVX from the upper end of the fome axis, I altered the pofition of the inftrument by the fcrews, until the plumb- line came to beat againft the point of the needle in the whole revolution of the inftrument, and there I fixed it as prepared for ufe.” So far Mr Cotes. The plumb-line or fine wire TVX was fufpended by a loop T upon a brafs pin that ferewed into the top of the axis AB ; a nick be¬ ing filed round the pin to flay the loop from Hiding out of it. Then by ferewing the pin in or out, the plumb-line was brought to the fame diftance from the axis AB as the point of the needle is at V : which was fixed in the end of a thick wooden pin Y, not in the axis of it, but towards one fide ; fo that by turning the pin round itfelf, in a hole bored through the axis AB, the needle’s point might deferibe a fmall circle, and be brought to touch the plumb-line when parallel to the axis of motion of the wood AB. Dr Smith gives the following defcription of an ex¬ cellent inftrument of this kind, in the noble colleftion rtf8 of the right honourable the earl of Hay. “ It is made Earl 0f all of brafs, except a fquare fteel axis ab 30 inches in Hay’s in¬ length. To one fide of the upper part of this axis^rument" there is fixed a fmall fextantal arch cd reprefented fe- parately at E ; its centre a being at the top of the axis a b. The telefcope MN is alfo 30 inches long, and is fixed along the diameter of a femicircle of the fame radius as the fextant, and concentric to it. The telefcope with the femicircle being moveable about this centre upon the plane of the fixed fextant a c d, may be fattened to it in any elevation by two nuts and fcrews c, d, fixed in the ends of the fextantal arch ; a circular flit being made all along the limb of the femi¬ circle for thefe ferew-pins to Aide in. Clofe under thefe arches, the axis a b is furrounded by a (hort cy¬ linder e, about an inch in diameter, well turned and polilhed. The lower end of the axis is formed into a fine conical point b. The frame in which the axis turns, is a long hollow parallelepiped wanting two 31 R fides. 5608 OPT Optical fides. Its other (ides fg, are two brafs plates, equal l.iitnimentsjn ]engt}, t0 t}ie part i e q{ the axjS} ancj are fcrewed together edgeways. It has For its bafes two equal plates h, it four inches £quare. In the middle of the upper fquare there is a round hole large enough to re¬ ceive the cylinder e, without touching it ; and over this hole is fixed a triangular hole in another plate ; one of whofe fides is moveable by a fcrew, to make all the fides of the triangle touch the cylinder. Up¬ on the lower fquare there lies a fmaller plate with a fine centre-hole to receive the point 3 of the axis. This centre-plate is moveable fideways by two fcrews at right angles to each other, which, when the frame is firmly fixed into a nitch of «Tfree-ftone pillar, will bring the axis ab exa&ly perpendicular to the horizon. This pofition is known by a fpirit-level lm fixed at right angles to the axis above the cylinder, upon the fide oppofite to the femicircle. Along the top of the level there is a Aiding pointer to be fet to the end of the air-bubble ; and when the pofition of the axis is fo adjufted by the fcrews below, that the air-bubble keeps to the pointer for a whole revolution of the in- ftrument, the axis a b \% certainly perpendicular to the horizon ; and then the line of fight through the tele- fcope defcribes a circle of equal altitudes in the hea¬ vens. There are feveral of thefe circles defcribed in the heavens, even when the telefcope is fixed to the fextantal arch. For the round hole in its focus has five wires parallel to the horizon at equal intervals from one another, as at k ; and they are crolfed at right angles in the middle by two other upright wires at a fmalfdi- ftanee from each other. The defign of fo many wires is to obferve when the fame ftar is fuccefiively covered by every one of the five, both in the eaft and weft; fo that the time of its paflage over the meridian may be had more accurately, by taking a medium among all the obfervations. The diftances between the five wires need be no greater than to afford time enough to write down the feveral obfervations, which muft be taken when the ftar is between the perpendicular wires. Ufts of thefe Time (hewn by a clock may be called mechanicaly memi dift!ngui/b from filar and Jidereal time. By obfer- ving when a ftar has equal altitudes before and after its culmination or appulfe to the meridian, we have the mechanical time of its culmination. Then by fubtrac- ting the fun’s right afcenfion computed to this me¬ chanical time, from the ftar’s right afcenfion determi¬ ned for the fame time, we have the folar time of the ftar’s culmination, and confequently the difference be¬ tween the mechanical and folar times. Thus, by finding the mechanical times, when the fame ftar culminates any two nights, rather at a di- ftance from each other than fueceflive, we have the difference between a fidereal day and a mechanical day; and confequently between a mechanical day and a fo¬ lar day of a mean length. Hence any number of mechanical minutes may be converted into folar or into fidereal minutes by the rule of three. Thefe obfervations will anfwer the purpofe the more exaftly as the ftar is nearer to the prime verti¬ cal; becaufe the variation of its altitude is heregreater in a given time, than if it were fituated in any other vertical oblique to the meridian. In the latitude of I C S. Part nr. 50 degrees an erfof of one minute in altittfde, at any Optical] point of the prime vertical, will caufe an error of fiHnflrumcd feconds in time ; and in the latitude of 55 degrees it will caufe an error of near 7 feconds; as that excellent geometer Mr Cotes has fhewn in his treatife con¬ cerning the Efii motion and Limits of Error} in mix¬ ed mathematics, publifhed at the end of his admi¬ rable book called Hannonia Menfurarum. It is alfo the fafeft to choofe a ftar as high as poffible, left a different ftate of the atmofpbere (hould caufe a diffe¬ rent refraftion of the vifual rays, and confequently an error in the times of obfervation. The folar time may alfo be found by obferving when the fun bimfelf has equal altitudes in the morn¬ ing and evening ; if we correft the time of the latter obfervation by a juft allowance for the variation of the fun’s declination, as follows. Upon a celeftial globe : let the pole be at P ; the vertex of the obferVer’s place 4, 1 : at V ; the complement of its latitude PV ; its rneri- £ dian PVBG ; a circle of equal altitudes ABCD, de¬ fcribed about its pole V; and palling thro’ the fun’s centre at A at the time of the morning obfervation, and through it at D at the time of the evening obfer¬ vation ; two circles of declination, PAF, PUl, cut¬ ting the equator FGHI, in F and I; a parallel of declination ACE, cutting the circle PDI in E, and ABD in C ; three equal vertical arches VA, VC, VD ; and laftly, a third circle of declination PCH cutting the equator in H. Now, had not the fun va¬ ried his declination from A or E to D, in the even¬ ing he would have had the fame altitude at C as in reality he has at D. And then as the angles VPC, VPA, would have been equal, fo the times of the evening and morning obfervations would alfo have been equidiftant from noon; being meafured by thofe angles, or by the arches GF, GH. Therefore the angle CPU, or the arch IH, which ifteafures it, is al¬ fo the meafure of a portion of time to be fobtra&ed from the evening obfervation, if the fun’s declination varies northwards, otherwife lobe added, to give the time fought equidiftant from noon. Let another circle of declination Vkl bifeft the fmall angle HPI, and confequently the fmall arches CD and HI in k and /. Draw the vertical arch /IV ; and in the triangle iPV, we have given PV the complement of the latitude, and P k half the fum of the given complements, PC or PA and PD, of the fun’s declinations at the times of the two obfervations, and laftly, the included angle k PV, by converting half the interval of time between the obfervations into degrees and minutes. Hence by tri¬ gonometry we have the angle P^ V, of an interme¬ diate magnitude between PCV and PDV, and there¬ fore fitter to be ufed inftead of either of them. Hence alfo we (hall have the arch IH ; by taking it in pro¬ portion to DE the difference of the declinations, as the co-tangent of the angle PCV, to the fine of the arch PC or PL For IH is to DE in a ratio compounded of IH to CE and of CE to DE, that is, of the radius to the fine of the arch PC, and of the co tangent of the angle DCE or PCV to the radius : as appears by taking away the common angle DCP from the right angles ECP and DCV ; and by cbhfidering the fmall triangle DCE, right-angled at E, as if it was rectili¬ near. The calculation fuppofes the fun’s centre has equal altitudes at A and D; which is agreeable to the Mechanifm obfervatipns that determine when his upper or his un- o t'c I ^cr ^as c breadth of it may cerning the be about half an inch more than the diameter of its iize of the aperture, or even three quarters, or a whole inch glafs and more, if its focal diftance be between 50 and 200 feet. Mr Huygens dire&s in general to make the breadth of the concave tool or plate in which an objeft-glafs muft be ground, almoft. three times the breadth of the glafs; though in another place he fpeaks of grinding a glafs whofe focal diftance was 200 feet, and breadth 8^- inches, in a plate only 15 inches broad. But for eye-glafles, and others of a (horter radius, the tool muft be in proportion to the breadth of thefe glafles, to afford fufficient room for the hand in po- lifliing. Huygens made his tools of copper or call brafs; which, for fear they fhould change their figures by bending, can hardly be caft too thick: neverthelefs he found by experience, that a tool 14 inches broad and half an inch thick was fufficient for grinding glaffes to a fphere of 36 feet diameter; when the tool I C S. Part III. breadth two or thure inches. Then having faftened Mechanifri 1 thefe plates flat againft the wall in an horizontal po- 0p°cal . ftion, with the moveable point in the pole ftrike ainftrumentj|ii true arch upon each of them. Then file away the —— brafs on one fide exaftly to the arch ftruck, fo ai to make one of the brafs edges convex and the other concave ; and, to make the arches correfpond more exa&ly, fix one of the plates flat upon a table, and grind the other againft it with emery. Thefe are the gauges to be made ufe of in turning the brafs tools exadly to the fphere required. But if the radius of the fphere be very large, the gauges muft be made in the following manner. Sup- PIafe_ tools for grinding. gauges muu oe mauc m luciumrwwg niauuvi. „x m, pofe the line AE, fig. 1. drawn upon the brafs plate, 'I to be the tangent of the required arch AFB, whofe radius, for example, is 36 feet, and diameter 72. From A fet off the parts AE, EE, &c. feverally equal to an inch, and let them be continued a little beyond half the breadth of the tool required. Then, as 72 feet or 864 inches is to one inch, folet one inch be to a fourth number ; this will be the number of decimal parts of an inch in the firft line EF, reck¬ oning from A. Multiply this fourth number fuc- cdfively by the numbers 4, 9, 16, 25, &c. the fquares of 2, 3, 4, 5, &c. and the feveral produds will be the numbers of decimal parts contained in the 2d, 3d, 4th, and 5th EF refpedively. But becaufe thefe numbers of parts are too fmall to be taken from a fcale by a pair of compafles, fubtrad them feverally from an inch reprefented by the lines EG; and the remainders being taken from a fcale of an inch divided into decimal parts, and transferred by the compaffes from G to F, will determine the points F, F, &c. of the arch required ; after which the brafs plate muft be filed away exadly to the points of this arch, and poliflied as before. 176 ; To apply the brafs tool to a turning lathe in order Of turning | to turn the concave furface of it exadly fpherical, let the brafs fig. 2. reprefent a view of fome part of the lathe,100 * j taken from a point diredly over it; \ei a b reprefent Fig 2, 3,4, a ftrong flat diflc of brafs half an inch thick at leaft. was ft rongly cemented upon a cylindrical ftone an inch having a ftrong iron fcrew-pin firmly fixed in the ,74 thick, with hard cement made of pitch and allies. Method of In order to make moulds for calling fuch tools as making theare pretty much concave, he direds that wooden 115011 s‘ patterns Ihould be turned in a lathe a|little thicker and broader than the tools themfelves. But for tools that belong to fpheres above 20 or 30 feet diameter, he fays it is fufficient to ufe flat boards turned circular to the length and breadth required. When the plates are caft, they muft be turned in a lathe exadly to the concavity required. And for this purpofe it is requi- fite to make a couple of brafs gauges in the following 17s manner. of making Take a wooden pole a little longer than the radius t>e£auScs* 0f tj)e fp!ler;cai furface of the glafs intended, and through the end of it ftrike two fmall fteel points at a diftance from each other, equal to the radius of the fphtre intended ; and by one of the points hang up the pole againft a wall, fo that this upper point may centre of it, and Handing out exadly perpendicular to one fide; by which it may be fcrewed into the end c of the mandrel or axis of the lathe, reprefented by c d. This difk is reprefented feparately in fig. 3. and muft be well foldered to the backfide of the tool e f, which therefore, in the middle of it, muft be made plane, and exadly parallel to the circumference of its oppofite furface, in order that the circumference may be carried round the axis of the lathe in a plane perpendicular to it. The mandrel or axis cd turns upon a point*/ in the puppet-head of the lathe, and in an iron collar reprefented by / /. Let ghik reprefent a board nailed fail on the other puppet-head; and let the concave gauge £ ^ belaid upon this board, with its concave arch parallel to the concavity of the tool e f, and be fcrewed down to the board with flat-headed fcrews funk into the brafs. Let l mn 0 reprefent fuch another board lying upon have a circular motion in a hole or focket made of the former, with the convex gauge Im fcrewed to the brafs or iron firmly fixed in the wall. Then take two under fide of it; fo that, by moving this upper board, equal plates of brafs or copper well hammered and the arch of the convex gauge may be brought to touclv fmoothed, whofe length is fomewhat more than the the concave one, and to Aide againft it. The turning breadth of the tool of caft brafs, and whofe thicknefs tool / S' is laid upon the moveable board, and is held may be a tenth or a twelfth part of an inch, and the fall to it by a broad-headed ferew at r, to be turned Part III.

To know < o °fcal w^et^er t^ie concave gauge be exaftly parallel to the llnftrLimentsconcavity t^ie to°^ ef Screwed fall to the mandrel, ——— diredt the point p of the turning tool to touch any i point of the tool ef near its circumference: then having fixed the turning tool pqby its fcrew r, turn the brafs tool e f half round, and move the upper board till the point p of the turning tool be brought over- againlt the fame mark upon the tool e f; and if it juft touches it as before when the gauges coincide, all is right. If not, the pofition of the head of the lathe may be altered a little by ftriking it with a mallet. But the beft way is, to make this examination of the fituation of the concave gauge, when only one end of it is fixed to the lathe by a Angle tack or fcrew, about which it may eafily be moved into its true pofition. And while the tool or plate ef \s turning, the fame examination of its parallelifm to the gauge muft be fre¬ quently repeated; otherwifc its furface will take a falfe figure. It is convenient that the upper board Imno (hould projeft over both the gauges ; and to keep its furface parallel to that of the under board, two round-headed nails, or a plate of brafs, as thick as the gauges, muft be fixed to its under furface, to¬ wards the oppofite fide/zc. Care muft be taken to drill the holes in the gauges, through which they are fcrewed to the boards, not too near the polilhed arches for fear of altering their figure by the yielding of the brafs. The tool and all the parts of the lathe muft be fixed very firm ; becaufe any trembling motion will caufe the graving tool p q Xo indent the brafs. After the tool is well turned, it muft be feparated from the brafs ab by melting the folder with live coals laid up¬ on it. In a fimilar manner may a convex tool be turned by tranfpofing the gauges. Mr Huygens advifes firft to form the plates or tools in a turning lathe ; and then to grind them together with emery; that is to fay, the concave and convex tool of the fame fphere together. But the tools of very large fpheres, he would have ground at firft quite plane by a ftone-cutter; and then ground hollow with a round flat ftone and emery to the proper gauge. And he prefcribes to ufe for this grinding firft a ftone half as broad as the tool, and after that another nearly of the whole breadth of it; and in this way of form¬ ing the tools, it will be convenient to tie a little frame of thick paper, or rather of thin pafteboard, about an inch high, round the tool, in order to keep in the emery ; and in grinding, the whole muft be made extremely firm. When the tool is to be po- lifhed, it muft ftill remain upon the ftone pedeftal; otherwife it will be in danger of bending a little in the operation. Of polilh- Forpolifhingthe tools when ground, Mr Huygens di- ing the refts the concave tool to be daubed with foap; after tools. which,he takes the round ftone above-mentioned, fome- what lefsthan the tool, (or the convex tool itfelf),and heats it; then he pours upon it fome hot melted cement (made of pitch and fine powdered and lifted aihes, as much as he can mix with it ), and then he turns over the ftone and cement upon the concave tool, into which alfo he had poured a good quantity of the fame cement; ha¬ ving firft laid three little pieces of brafs, of equal thick- neffes, on the circumference of it, in order to prefs and keep this cruft of cement of an esad equal ihicknefs ICS. 5611 in all its parts; and thus he lets them cool together. Mechanlfm Then taking the ftone from the tool, and tnrning it n . up, he lifts upon the cement that Hicks to it a cruft of very fine emery; and with a flat iron fpatula, about one third of an inch thick, gently warmed, he prefles light¬ ly the emery, to ftick to and incruftate upon the ce¬ ment. The whole is then gently warmed, viz. the ftone, cement, and emery, and he again replaces it upon the concave tool, and leaves it again to cool; fo that he has by this means a cruft of emery exaftly of the figure of his tool; and with this he polilhes the tool dry, without the addition of any wet, prefiing it hard on the furface of the tool. To prefs it the harder, he places upon it a long pole, a little bent, to make it fpring, whofe upper end is fixed to the ceiling of the room, or elfe is prefled downwards by a ftrong iron fpring; and he thinks it is neceflary to have two per- fons to rub the ftone upon the tool. Here, however, it muft be obferved, that great care muft be taken in this, and in all cafes where this way of grinding by a pole is made ufe of, to fix the point of prefiure exadily in the middle. To bring the concave tool ftill nearer to perfe&ion, take equal pieces, about an inch fquare, of blue hone, fuch as are ufed by engravers for polifhing their cop¬ per, and place as many of them as you can upon the furface of the tool to be polifhed, laying the grain of them, fome one way, fdme another; fticking them as clofe as you can to one another with foap and com¬ mon white ftarch: then fill up all the interfticesof the hones with clean dry fand, to about two thirds of the tbicknefs of the hones; then having a border of paper or pafteboard put round the tool as before, (hake the tool gently, that the fand may equally fubfide, and blow it every where to an equal depth with a pair of bellows. Then take fome hard cement, extremely hot, and pour it all over the hones ; then having cleaned the ftone, or convex tool, which before was incrufta- ted with pitch and emery, place this ftone (or convex tool) warmed, on the top of the cement, and let all cool together. Then rubbing the tool with this po- lifher made with hones, by applying your pole to the top of the ftone as before, you will know when the tool is brought to perfection, by wiping off the filth, in which cafe all parts of it will appear equally bright by looking upon it obliquely againft the light. If you would ufe this poliflier again, it muft be kept in- a cool cellar, leaving the hones uppermoft; otherwife in warm weather they will change their fituation in the cement, even by their own weight. I7g The cement ufed for faftening the glaffes is. made Cement for of feveral different compofitions, according to the fancy fjl^en1'n1j>ioa of the operator. Cherubin informs us, that it was"162,1 ^ ufually made of common black pitch and fine fifted vine-afhes: but he himfelf made it of rofin and ochre, or rodn and Spaniflr white ; pounding the rofin firft, and mixing it with a due quantity of the powder, and then fifting the mixture upon hot melted pitch, and, . while hot, well mixing and incorporating the whole. By others, the cement is made of pitch and common coai-afhes fifted fine. In all cafes, it is harder orfoft- er, as more or lefs of the afhes or other fine powder is put into it: and in the prefent cafe, for polifliing thefe tools, it muft be made as bard as poffible, by putting in a large quantity of aftus; for otherwife, if the ce- 561s OPT Mechanifm ment is not hard enough, the particles of the emery will be loofened by the heat in grinding, and then will ihtmtiikiiu,°nly run round upon the tool, without working out —the little inequalities thereof. If the emery (hould be found to grow blunt, a very little more of it may be dufted dry upon the tool, by which its (harrpnefs and cutting quality will be a little recovered; but if the cement be fufficiently hard at firft, the emery will al- n? ways remain fufficiently fharp. Of choofing -phe beH 0f gjafs ;s perfedlly white; but great 1 e 2 a s* c3re muft be taken in choofing it totally free from veins. To difcover thefe veins, one fhould look very obliquely againft a fmall light in a room otherwife dark. In this manner one may examine pieces of a polilhed looking-glafs, of which objedt-glafies are fometimes made; but becaufe thefe are fddom of a fufficient thicknefs for this purpofe, it will be proper to take fome pieces of the fame fort of glafs before it is poliPned, and get it ground to an equal thicknefs and polKhed a little by the common glafs-grinders, in order to judge what pieces are fit for ufe. Sometimes little veins will appear like fine threads, which fcarce do any harm. Sometimes their imperfe&ions cannot be difeovered by the former way of trial; and yet af¬ ter the glafs is well formed and polilhed, they will ap¬ pear by refledlion in the following manner. In a dark room place the glafs upright upon a table, turning that fin face from you which is fufpedted to be faulty; then holding a lighted candle in your hand, fo that the middle of the broad light refledfed from the firft furface may fall upon your eye, recede from the glafs till the rays refteded from the back furface lhall juft begin to invert the candle; then the whole glafa will appear all over bright, and then you will difcover its defeds, and the imperfedions of the polilh.- When the glafs is a portion of a large fphere, we ufe a fmall perfpedive, three or four inches long, to magnify the 180 defeds. Howglafles The pieces of glafs above-mentioned fhould be fmoothed milc^ broader than the intended objed-glafs, that there and round- ma7 room enough for choofing the beft part of ed. them. For planing and fmoothing thefe large pieces of glafs, plates of caft-iron may be made ufe of; fuch as are fold at the iron-mongers (hops, after they have been ground and planed on a ftone-cutter’s en¬ gine. Upon the plate of glafs, with a diamond- pointed -compafs, ftrike a circle reprefenting the ob- jed-glafs; and alfo another concentric circle, with a tadius about a tenth or twelfth part of an inch bigger; And alfo two other fuch circles, on the -other tide of the glafs, diredly oppofite to the former; which may be done by means of the circular glafs to be after¬ wards defcribed. The larger parts of the glafs may be feparated from the outward circle by a red-hot iron, or by a ftrong broad vice, opened exaftly to the thick- nefs of the glafs. The remaining inequalities may be taken off by a grind-ftone ; beginning with the lar- geft firft, and taking care that they do not fplinter. Then, having warmed the glafs, cement a wooden handle to it, and in a common deep tool for eye- glaffes, making ufe of white clear fend and water, grind the circumference of the glafs exaftly true to the innermoft circle on each fide of it. Then, having ‘made a great many fmall cavities with a punch upon one fide of a round copper-plate, and having fixed the I C S. Partin. other fide of it upon the middle of the round glafs, by Mechanif cement made with two parts of rofin or hard pitch, °! and one part of wax, place the fteel-point pf the fpring- inftr„mer ing pole above defcribed, being 14 or 15 feet long, ; into that cavity of the copp’er plate which lies neareft the thickeft part of the glafs; then work the glafs by the pole with fend and water upon a flat plate of caft iron, of a round figure, the plate having been planed with fend and water by a ftone-cutter, Then having examined the thicknefs of the glafs in feveral places by a hand-vice, which is better than a pair of cal¬ lipers, by repeating the fame operation, it will foon be reduced to an equal thicknefs in all its parts. To¬ wards the end of this operation it will be convenient to make ufe of fifted emery, becaufe the fend will fcratch too deep : and then it will alfp be neceffary to place the fteel-point of the pole exa&ly over the centre of the under furface of the glafs; otherwife that furface will take a cylindrical or convex figure, even though it was exactly plane before you began to grind it; and when concave glaffes are to be polifhed, it is alfo ab- fohuejy neceffary to place the point of preffure exaflly over the centre of the under furface of the glafs. To bring one of the little cavities in the copper-plate ex- adlly over that centre, a circular glafs is made ufe of, formed from a broken looking-glafs with the quick- filver rubbed off. On this muff be defcribed, with a diamond-pointed compafs, eight or ten concentric circles, about a quarter of an inch diftant from each other, fo that the larger circles may be fomewhat big¬ ger than the circumference of the glafs to be poliftied. Lay this circular glafs upon the furface of the glafs to be poliftied; and move it to and fro till you perceive that the circumference of the glafs to be poliftied is exa&ly parallel to the neareft circle upon the circular glafs; then, having inverted both the glaffes, lay the • circular glafs upon a table, and having laid a fmall live coal upon the copper plate, to make it moveable on the cement, place one point of a pair of compaffes in one of the little cavities, and move the copper till a cir¬ cumference defcribed with the other point coincides ! exa&ly with any one circle upon the circular glafs, and the bufinefs is done. It is convenient to pafte three flender ftireds of fine linen diredfed towards the : centre of the circular glafs, that the other glafs may not Aide too eafily upon it, and that they may not j fcratch one another. The cavities punched in the cop¬ per plate, and alfo in the point of the pole, (hould be triangular, to hinder the rotation of the glafs; which is ftill more neceffary in giving it the laft polifh. Here alfo we muft obferve whether the circumference re¬ mains exa&ly circular on both Tides of it, which muft j be tried with compaffes: and if it be not, it muft be 1 corredted again by grinding it exadtly circular in a common tool for making eye glaffes; which will,con¬ tribute very much to its taking an exadl fpherical fur- j face when it comes to be ground in its proper tool. 1 For if any part of the circumference be protuberant, i it will hinder the adjoining parts of the furface from wearing fo much as tliey ftiould do; and of confequence { will fpoil its furface. When the glafs is thoroughly planed and rounded as above, take away the plate with the feveral cavi¬ ties, and, with fome of the feme cement, fix on a 1 Imaller round piece of brafs or rather fteel truely flat, and i PartUI. OPT .Mechamfm and turned about the bJgnefs of a farthing, but thicker, °( . having firft made in the centre thereof, with a trian* ilnftrnnients Su^r fteel punch, a hole about the bignefsofa goofe* I— quill, and about the depth ofTV of an inch ; and at the vefy bottom of this triangular hole, a fmall round hole mull be punched, fomewhat deeper, with a very fine fteel punch. A fmall fteel point about an inch long mull be truly fhaped and fitted to this triangular hole, and, at the very apex, to the fmall, round, deeper i|?Iate impreffion. Neverthelefs, it muft not be fitted fo ex- fCXXVII. aaiyj jjU{ t}jat jt may have feme liberty to move to ' and fro ; the apex always continuing to prefs upon !| the furface of the round hole below. This fteel tri¬ angular point muft be fixed to one end of a pole; to the other end of which another round iron point muft be fixed, of about five or fix inches long, to play freely up and down in a round hole in a piece of brafs let into a board fixed in the deling for that purpofe, perpendicularly over the bench, and over the centre of the tool, which muft be ftrongly and truely fixed ho- Ir tizontally thereon. Mr Huygens diredls the brafs plate to be fixed to the glafs by means of cement, and takes no notice of any other method whatever; though it is plain, that it is hardly poffible, in this, or any other cafe, to bring the cement to a fluidity fufficient to fix two plane furfaces exa&ly parallel to one ano¬ ther, without heating the glafs, and the brafs alfo, to a very great degree, and thus endangering the glafs confiderably. To avoid this, fome have ufed plafter of Paris ; others cement an intermediate glafs to the brafs or wood, and then fix the glafs to be ground to the outward furface of the cemented glafs with com¬ mon glue. It may eafily be done, however, with common ifinglafs or fifti-glue, which will run very fluid, and will fix the glafs and the brafs of itfelf ftrongly together. Some common foft red wax is to be ftuck on the edges of the brafs, to keep wet from I H gctt'ng to the glue. For grinding glafles truely plane by this method, Mr Huygens prescribes the pole to be about 15 feet long ; but, in grinding upon a concave plate, the pole is moft conveniently made of the fame length with the radius of the fphere, though Dr Smith is of opinion that it would not be material if made confiderably fliorter, as the height of the room may allow. It is neceffary to have, lying by, an ordinary piece ofcoarfe glafs ground in the fame tool, called zbruifer; where¬ by, when any new emery is laid on the tool in grind¬ ing the glafs, it muft be firft run over and fmoothed, for fear that aiiy little coarfe grains (hould remain and fcratch the glafs. Things being thus prepared, fome pots of emery of 'various finenffles muft be prepared. Take of the rougheft fort a fmall half-pugil, ‘wetting and daubing it pretty equably on the tool : then lay on y6ur glafs, and fix up the pole, continuing to grind fbr a quarter of an hour; not prefnng upon the pole, but barely carrying the glafs round thereby : then take the like quantity of fome fine emery, and work another quarter of an hour therewith ; and then take the like quantity of emery ft ill finer,’ and work for the-fame time: after which you muft work for an hour and an half with fome of the fineft emery you have, taking away by little and little fome of the emery with a wet fponge. It amft neither be ICS. 5615 kept too moift nor too dry, but about the confiftence Merhamim of pap. Much depends on this laft circumftance. For, °f if it is too dry, the emery will clog and flick, and in- Inftr^*)U corporate in fuch a manner as to cut little or none at all, unlefs here and there, where its body chances to be broke ; and in thofe places it will fcratch and cut the glafs irregularly : or if it is too much diluted, it will, from the irregular reparation of its parts, cut in fome places more than in others, as in the former cafe. But Mr Huygens tells us, that this method of ufing various forts of frefh emery is not good ; as in this way, he finds by experience, that the beft glafles are often fcratched. For this reafon, he advifes to take a large quantity of emery of the firft or fecond fort, and wmrk with it from firft to laft, taking away by little and little every half hour, or quarter of an hour, more and more of the emery with a wet fponge. By this means he could bring the glafs extremely fmooth and fine, fo that a candle or fafh window could be feeu through it pretty well defined ; which is a mark of its being fufficiently well ground for receiving the laft polifli. But, if the glafs has not acquired this degree of tranfparency, it is certain, fays Mr Huygens, that too much emery remains ; and therefore it muft ftill be diminiflied, and the operation continued. He found common well-water moft proper in this operation of grinding; and he took care to move the glafs in circles, taking an inch beyond the centre of the tool, and fomewhat beyond its outfide; and he found in a glafs of 200 feet, whofe diameter was 8|r inches, which he ground in a tool of 15 inches diameter, that the figure of the tool in grinding would alter confiderably, unlefs he carried the glafs round an inch beyond the centre of the tool one way, and 3^ inches beyond the fleirts of it another way; but if he carried it no farther than a ftraw’s breadth beyond the fkirts of the tool, and of confequence farther beyond the centre, the glafs would always grind falfely, fo that he could never afterwards bring the outfides of it to a true and fine polifti. When you firft begin to grind, and the emery be¬ gins to be fmooth, the glafs will flick a little to the tool and run ttiff. Then frefh emery is to be added. When it afterwards comes to be polifhed, it will, if large, require a confiderable ftrength to move it; but this inconvenience will happen lefs in grinding by the pole than in grinding with the hand. For the warmth of the hand makes the fubftance of the glafs fwell; and not only increafes the flicking of the glafs, but in fome meafure may fpoil the figure of it, as alfo of the tool. When it is ground with the pole, it never flicks very ftrongly, unlefs when you take the glafa off from the tool, and keep it from it for fome time, and then apply it to the tool again : and this in large glaffes ; for by this means the glafs gets from the arr a greater warmth than it had on the tool ; and being again applied to the tool, its lower furface is fuddenly contradied by the cold, and thus flicks to the tool. Wherefore, fays Mr Huygens, you muft in that cafe- wait till the glafs and the tool come to be of one tem¬ perature. The like effedt is obftrvable in grinding when there is a fire in the room ; and hence we may fee the great nicety requifite in grinding thefe large glaffes, and the neceffity of attending even to the mi- nuteft circumftances. In-- 56i4 'Mech^nilm of Optical Initruments Plate CCXXVII. % 6. OPT Inftead of emery, Father Cherubin prefcribes the grit of a hard grind-ftone, well beaten into fine powder, and fifted. The fame thing hath been done by com¬ mon white-fand wafhed clean, taking away by little and little the grit as it became finer and finer. Nay, glafles have been frequently polilhed off in this man¬ ner without the ufe of any other material whatever. This method is called drying off on fond; becaufe, as the matter grows finer and finer, they wet it lefs and lefs, till for the laft quarter of an hour (the whole work lafting nearly two hours) they only wet it by breath¬ ing upon it; and at the very laft, not at all. This me¬ thod, however, is now entirely difufed; for which Dr Smith afiigns, as one reafon, the violent labour requi- fite at the laft : another and better reafon, he fays, may be, the great improbability of grinding or po¬ licing true by this method, by reafon of the uncer¬ tain and unequal force of the hand. But if this laft is the reafon. Dr Smith is of opinion, that the method might be reftored, and greatly improved by adding a pole, and fpring to prefs down the pole, or fome ana¬ logous contrivance. And in all methods of grinding hitherto invented, the artift muft allow time to bring his glafs by grinding to the fmootheft and fineft fur- face that he poffibly can, before he attempts to give the laft polifti. For the fmoother you bring it in grinding, the lefs labour you will have in policing; in which confifts not only the greateft difficulty, but the greateft danger of {polling all you have already done.^ In order to give the laft and fineft poliffi to glafles, Mr Huygens dire&s us to proceed as follows. “ Ha¬ ving removed the little brafs plate from the glafs, take a very thick flate, or rather a block of blue or giey ftone ; let it be half an inch thick, and let it be ground true and round at the ftone-cutter’s ; its diameter be¬ ing fomewhat fmaller than the diameter of your glafs, leaving a hole quite tlfrough in the centre, of about an inch diameter. Then make fome cement of two parts rofin or hard pitch, and one part wax ; and taking a piece of thick kerfey cloth, truly and equally wrought, cut this cloth round, and leave a like hole one inch diameter in the middle. Then warming the ftone and alfo warming the glafs, and fpreading thinly and equably upon them fome of this cement, lay on the cloth, and thereupon lay alfo the glafs, having left in the middle a fpace the breadth of a fhilling unce¬ mented and blacked with a candle. Then provide an hollow conical plate of iron or fteel (fhaped like an high-crowned hat) having the balis of the cone i inch diameter, and having round the bafis a.flat border about inches diameter, and having the depth or al¬ titude of the cone exaftly of the thicknefs pf the flate, cloth, and cement, to which the glafs is fixed. The vertex of this cone muft go down thro’ the flate and cloth; fo that being cemented on the flate, thefaid vertex may approach to the glafs within a hair’s breadth, and lie perpendicularly over the centre of the lower furface of the glafs: and this muft be adjufted by the circular glafs defcribed above. Within the vertex of this hollow cone, the lower point of the pole is to be applied in polifhing ; but it may be firft pro¬ per to be obferved, that fifti-glue and a brafs plate, in lieu and of the dimenfions of the aforefaid flate, -may perhaps be better. Mr Huygens obferves alfo, that the angle of the cone ffiould be 80 or 90 de- I C S. Part m\ grees, and that the hollow vertex of it ffiould be folid Mechaniij enough to receive a fmall impreffion from a round fteel °( punch, to put the point of the pole into, which might inftrumet otherwife have too much liberty, and flip from the— 1 vertex. The defign of the black fpot in the middle of the glafs, is to difcover by the light of a candle J obliquely refle&ed from your glafs, after it has been poliffied fome time, whether it be perfectly clear, and free from the appearance ofany bluifli colour like that of allies. Before the work of poliffiing is begun, it is proper ! to ftretch an even well wrought piece of linen over the tool, dufting thereupon fome very fine tripoly. Then -| taking the glafs in your hand, run it round 40 or 50 . times thereupon; and this will chiefly take off. the roughnefs of the glafs about the border of it, which | otherwife might too much wear a^vay the lower parts of the tool, in which the glafs is chiefly to obtain its laft poliffi. This cloth is then to be removed, and the glafs is to be begun to be polifhed upon the very na¬ ked tool itfelf. But firft there is to be prepared fome 1 very fine tripoly, and alfo fome blue vitriol, otherwife I called cyprion, Englifli and Hungarian vitriol finely I powdered : mix four parts of tripoly with one of vi« | triol: 6 or 8 grains of this mixture (which is about the quantity of two large peas) is fufficient for a glafs 5 inches broad. This compound powder muft be wet¬ ted with about 8 or 10 drops of clear vinegar in the middle of the tool; and it muft be mixed and foften- ! ed throughly with a very fine fmall mullet. Then with a cqarfe painting brufh, take great care to fpread it thinly and equably upon the tool, or at leaft upon a much larger fpace in the middle of it than the glafs | {hall run over in the poliffiing. This coat muft be laid on very thin, (but not too thin neither), otherwife it will wafte away too much in the poliffiing, and the tool will be apt to be furrowed thereby, and to have its fi¬ gure impaired; infomuch that fometimesa new daub¬ ing thereof muft be laid on, which it is not eafy to do I fo equably as at firft. This daubing muft be perfefl- ly dried by holding over it a hot clean frying-pan, or | a thin pan of iron, with light charcoal therein for that purpofe ; then leave all till the tool is perfe£Uy cold. Then having fome other very fine tripoly very well wafhed and ground with a mullet, and afterwards dried j and finely powdered, take fome of the fame and ftrow it thinly and equably on the tool fo prepared; then take your coarfe glafs which lay by you, and fmooth j all the faid tripoly very equably and finely: then take your glafs to be polilhed, and wipe it thoroughly dean from all cement, greafe, or other filth which may ftick to it, with a clean cloth dipped in water, a little tinged with tripoly and vitriol; then taking your | glafs in your hand, apply it on the tool, and move it j gently twice or thrice, in a ftraightline, backwards and forwards; then take it off, and obferve whether the marks of the tripoly, fticking to'the glafs, feem to be equably fpread over the whole furface thereof; if not, it is a fign that either the tool or the glafs is too warm; then you muft wait a little and try again till you find the glafs takes the tripoly every where alike. Then you may begin boldly to poliffi, and there will be no great danger of fpoiling the figure of the glafs; which in the other cafe would infallibly happen. If the tool , be warmer than the glafs, it will touch the glafs hard¬ er Part III. Mechanifm er In the middle than towards its circumference ; be- . caufe the upper furface of the tool being fwelled by i infjruments hcst will become too flat. On the contrary, if the . glafs be warmer than the tool, it will bear harder to¬ wards its circumference than at the centre; bCcaufe the inferior furface of the glafs is contra&ed by the cold- nefs of the plate, more than the fuperion Mr Huygens fays, that if the work of polifliing were to be performed, by ftrength of hand only, it would be a work of very great labour, and even could not be performed in glafles of 5 or 6 feet focal di- ftance : and he feems to think it abfolutely neceflary that an extraordinary great force or preflure (houldbe applied upon the glafs. For this purpofe he has there- - fore contrived and defcribed two methods for fufficient- f Seen0i8i.]yincreafing the pre(fure|. both of which chiefly con- fift in applying the force of a ftrong fpring to prefs H ig, down the centre of the glafs upon the polilher. t Sir Ifaac This operation of polifliing, as it is one of the moft I Newton's difficult and nice points of the whole, hath been very i of varioufly attempted and defcribed by various authors. 3 |>« 1 ing. Newton, Pere Cherubin, Mr Huygens, and the common glafs-grinders, have taken different me¬ thods in this matter. Sir Ifaac is the only perfon who feems not to infill on the neceflity of a very violent and ftrong prefiure. In the Englifh 8vo edition of his Op¬ tics, p, 95. he hath thefe words: “ An objecl-glafs of a 14 foot telefcope, made by an artificer at London, I once mended confiderably, by grinding it on pitch with putty, and leaning very eafily on it in the grind¬ ing, left the putty fliould fcratch it. Whether this may not do well enough for polifhing thefe refleding glafles, I have not yet tried. But he that fhall try either this or any other way of polifhing which he may think better, may do well to make his glafles ready for polifliing by grinding them without that violence wherewith our London workmen prefs their glafles in grinding : for-by fuch violent preffure, glaffes are apt to bend a little in the grinding, and fuch bending will certainly fpoil their figure.” As to his own method of polifliing glafs, he no where exprefsly deferibes it; but his method of polifli¬ ing refleding metals he doth ; and it was thus, in his own words, p. 92. “ The polifh I ufed was in this manner. I had two round copper plates each fix inches in diameter, the one convex the other concave, ground very true to one another. On the convex I ground the objed-metal or concave, which was to be polifhed, till it had taken the figure of the convex and was ready for a polifh. Then I pitched over the con¬ vex very thinly, by dropping melted pitch upon it, and warming it to keep the pitch foft, whilft I ground it with the concave copper wetted to make it fpread evenly all over the convex. Thus by working it well, 1 made it as thin as a groat; and after the convex was cold I ground it again, to give it as true a figure as I could. Then I took putty, which I had made very fine by wafhing it from all its groffer particles; and laying a little of this upon the pitch, I ground it upon the pitch with the concave copper till it had done making a noife ; and then upon the pitch I ground the obje6l- metal with a brifk motion for about two or three mir nutes of time, leaning hard upon it. Then I put frefh putty upon the pitch, and ground it again till it had done making a noife, and afterwards ground the ob- jeS-metal upon it as before. And this work I re- Vol. VIII. 2 5(>I5 peated till the metal was polimed, grinding it the laftMeehamt 1 time with all my ftrength for a good while together, and of frequently breathing upon the pitch to,keep it moift> inftrumjate At CC rs reprefented a fquare beam of wood, a CCXXVII. little longer than the diameter of the tool, and about %• 7’ i-r inch thick : the two extremities of it at C and C 185 are bent downwards, and then are again dire&ed pa- Mr Huy- rallel to the whole length, and ferve for handles for chines7o~ ^ wor^man to lay'hold of. In the middle of this foMfiog1 beam there is fixed an iron fpike, fo long, that when the lower furfaces of the handles, C,C, are placed upon a plane, the point of the fpike fhall juft touch the plane. This point preffes upon the apex of the hollow cone, which defcends through the hole in the flate, which, by the interpofition of a cloth, was cemented to the glafs B lying upon the tool A. To increafe this preffure, a fort of bow, DED, is fhaped out of a deal-board, half an inch thick, and five feet long, being feven inches broad in the middle, and tapered narrower to¬ wards its extremities, fo as almoft to end in a (harp point. The middle of the bow is fixed to the floor by an iron ftaple at E driven crofs it; and is bent into an arch by a rope FIIF; to which two other ropes are tied at I and I ; the interval II being equal to the length of the beam CC. One of thefe ropes ICCG goes over the back of the beam CC, palling through a hole in each handle at C and C, and then is lapped round a cylindrical peg at G, that pafles through two wooden chaps, to the bottom of which the other rope is tied that comes from the other I. So that, by turning the peg G, to lap the rope about it, the bow DD may be bent as much as you pleafe. The tool A is placed upon a ftrong fquare board fixed to the table O on one fide, and fupported on the other fide by the poft P. Then the workman fits down, and taking hold of the handles CC, he draws the glafs to him and from him over the tool A, with a moderate mo¬ tion ; and after every 20 or 24 ftrokes, he turns the glafs a little about its axis. This way of policing took up two or three hours, and was very laborious as well as tedious; becaufe the gtafs, being fo much prtfled downwards, was moved very flowly. j-lg. g, Inftead of the bow DD, Mr Huygens afterwards in¬ vented another fpring by Hoping the flat ends of a couple I C S. Tart III.!! of dealboards * « y> and by nailing the flat Hopes to- Mechanifi^ |t gether very firmly, that the boards might make an acute | angle One of thefe boards fo joined was laid up- L on the floor under the polifliing table, the endsbe- -j p ing under the middle of the tool A.. So that they lay quite out of the way of the workman, who before was a little incommoded by the ends of the bow DD. The boards at the end « were 8 or to inches broad^ and from thence went tapering almoft to a point at fi and 7. The board lying upon the floor, the end p, of the upper board, was pulled downwards by a rope 0 f £ that paffed under a pulley *, fixed to the floor, and then was lapped round a ftrong peg £ that turned (tiffin a hole in the floor. Under the end y the middle of a ftrong (tick fy* was fixed at right angles to the board «y, and cords were tied to each end of this (lick at which went over the polifliing beam C, C, as in the former machine. This (tick was lift¬ ed up but very little from the floor at the time of po¬ lishing ; and* by confequence the ropes J C, ^ C were long enough to give liberty of motion to the polifliing beam CC. Two iron pins 8, «, pafling through the ends of the boards at «, were ferewed into the floor; but the heads of the pins flood up above the boards, to give them liberty to rife up when the rope P * £ was ftretched. To facilitate the labour of moving the glafs back- Fig. 1. wards and forwards in the tool, Dr Smith made the following addition to the machine. At M is repre¬ fented a ftrong hand made of wood or iron, having a fquare cavity cut through the bottom of it, for the poliftiing beam CC to pafs through, not tight, but at fome liberty. To one fide of this hand M is annexed a long board LL, by means of an iron bolt. The breadth of the lower furface of this board LL is equal to the breadth of the hand M, being 2i inches; its thicknefs is half an inch, and its length equal to three femidiameters of the tool. The board LL muft be drawn backwards and forwards lengthwife over a block H firmly fixed to a table O ; the thicknefs of the block being fucb, that the board LL may lie an inch higher than the furface of the tool A. The wooden hooks at n, and the pins at S, keep the mo¬ tion of the board in the fame direflion, by hindering it from flipping either upwards or Tideways. Over this board, at right angles to it, and over the middle of the block H, there lies a wooden roller, having a ftrong iron axis which turns in the holes of two iron plates fixed to the ends of the block. The thicknefs of the roller is about an inch and an half. Thro’ two holes bored thro’ this roller, and made wider at one end of them, two ftrong cords are made to pafs with knots at one end of them, to be drawn into the wider parts of the holes, that they may neither flip through, nor ftand out from the roller. Then each cord is lap¬ ped round the cylinder feveral times ; and one end of each is pegged firmly into the board LL at the end towards M, and the other ends of them are lapped round a peg at N ; which being turned round, will ftretch the cords as much as you pleafe. At one end of the axis of this roller there is a handle Q^which be¬ ing turned round backwards and forwards alternately, the board LL with the glafs annexed to it is moved to and fro, fo far, that about a third part of its dia¬ meter flioots both ways over the margin of the tool. The. I Part III. OPT Mechanifm The fplke m the middle of the beam CC preflea the | 0 °f j glafsa little obliquely, becaufe the hand M holds the 1 Inftriiments^earn not ^ut fonaewhat loofcly, to the end I— -that the glafs may pafs over the tool without trem¬ bling. Neverthelefs this inclination of the fpike mull be very fmali; and may eafily be increafed or dimi- nifhed feveral ways. Two pins or flops muft be fixed to the under furface of the board LL, to determine the length of the ftroke. The tool A, or rather the ftone to which it is cemented, is fqueezed faft between the block H, and a ftrong flop on the oppofite fide of the flone, by the interpofition of a wedge. The work¬ man fits upon a round ftool; and, when one hand is tired with turning the roller, he applies the other; and therefore is not fo foon tired as with the other machine, which required both hands, and alfo a reci¬ procating motion of the whole body. A longer handle Qjc wa's alfo made, which turned at both ends, for the convenience of ufing both hands at once. After every 20 or 24 ftrokes, it is neceflary to give, the glafs a fmali turn about its axis; which is eafily done by laying hold of the flate fixed to it, with one hand, while the other hand goes on with the policing motion. The tool muft alfo be moved a little after every 25 or 50 ftrokes, by drawing it half a ftraw’s- breadth towards that part of it which the glafs has left, and by drawing it back again after as many more ftrokes. At the beginning of the work the tri¬ poly will be gathered into little lumps in fome places of the tool, but will be difperfed again in a little time; and then the area of the tool will become perfectly fmooth. If the tripoly does not appear to flick equally to the glafs in all parts, and to be diffufed over it in {lender ftraight ftreaks, the frying-pan with coals in it muft be held over the tool again, till you perceive the area, or coat of tripoly is not quite fo cold as the other parts of the tool. Then let tripoly be rubbed upon the tool again, and let the glafs be prefled over it with your hand, to try whether it flicks equally to the glafs in every place. When it does, you may proceed in the work of polifhing. But when vitriol is ufed inftead of verdigreafe, all that is faid about warming the tool may be omitted ; becaufe thefe coats always touch the glafs as they ftiould do, and ftick better than before. The tool ought alfo, without being warmed, to be rubbed with tripoly over the coat, that the latter may be preferred more entire, and that the glafs may touch it better, which muft always be repeated after 200 or 400 ftrokes in poliftiing. The glafs fhould al¬ fo be taken from the tool after 200 ftrokes, by with¬ drawing the boh L, which connedfs the hand M to the board LL, and by removing the beam CC. Then rub your finger upon the glafs, or a clean rag, or a bit of leather, to examine how much it is po- i$ feven or ei‘ght illche8 broad, Ufed in po- againft a board fixed to the fide of a wall. It lifting. turns eafily about an axis, and has 24 teeth, like thofe of a faw, which are pufhed round by a bended wire TYX in the following manner. The wire turns about a centre Y ; and while one end of it is polled by the firing TV tied to the end of the board LL, the op¬ pofite end YX pufhes back a long fpring RS, fixed to the board at R ; which, by preffing upon the wire at ICS. 5617 S, caufes the part YX to bend a little* and fo the Mecbanifnv point X, in returning to the wheel (the firing being °( . relaxed) falls a little lower into the next tooth, arid jn4^ments pufhes it forward in thepofition reprefented in the fi gure. There is a fpringing catch at A, vvhich flays the wheel after every ftroke at X. Laftly, there is a pin fixed in the circumference of the wheel at Z, which, by preffing the tail of a hammer, and letting it go again, caufes a bell to found after every revolution of the wheel, and gives notice that the glafs muft be turned a little about its centre. It is eafy to under- ftand, that another piece of wheel-work, having three or four indexes, whofe revolutions are in decimal pro- greffion, may be fixed to the block H, and impelled by the ftrokes of the board LL; by which means, without any trouble of counting, one may be informed how many ftrokes go to polifh a glafs. A glafs five or fix inches broad requires about 3000 ftrokes upon each furface to bring it to perfeftion. You muft care¬ fully examine the middle of the glafs oppofite to the blacking, whether any place appears darkifh or of an afh-colour; or whether any fmali fpots appears by an oblique refleftion of the light of a candle, or of a fmali beam of light let into a dark room; for the other parts of the glafs will appear perfeftly fine much foon- er than the middle. After the glafs has been fufficiently polilhed, let the ftone, the cloth, and the cement, be warmed over a pan of charcoal, till the cement grows fo foft that the glafs may be feparated from it by a fide-motion. Then,, whatever cement remains upon the glafs muft be wiped off with a hot cloth dipped in oil or tallow, and laft of all with cleaner cloths. Then if it does not appear perfectly poliftied, (for we are often deceived in this point), the work muft be repeated again, by glueing the glafs to the flate as before; then it muft be wiped very clean, and made a little rough, as we faid before. We muft alfo lay a new fund, or coat, upon the tool, if the old one be fpoiled ; provided no other glafs has been poliffied in the tool in the mean time. The old fund may be waftied off from the tool with a little vi¬ negar. Laftly, take care always to choofe the thick- eft and cleareft pieces of glafs, to avoid a great many difficulties that arife from the unequal preffure in po- lilhing. § 3. To Centre an Objett-glafs. A circular objeft-glafs is faid to be truely centered when the centre of its circumference is fituated in the axis of the glafs, and to be ill centered when the centre of the circumference lies befide the axis. Thus, let d be the centre of the circumference of an objedl- Plate glafs ab c; and fuppofe e to be the point where its CCXXVIll axis cuts its upper furface. If the points 5618 OPT Ulechanifm the planes of the bafesof the tubes be exa&ly perpen- °? dicular to their fides. Place the bafe of the narrower hftrumentstub€ uPon a fmooth brafs P,ate or a wooden board of an equal thicknefs; and with any (harp-pointed tool defcribe a true circle upon the board round the out¬ ward circumference of the bafe ; and upon the centre of this circle, to be found when the tube is removed, defcribe a larger circle upon the board. Thefe two circles (hould be fo proportioned, that the one may be fomewhat greater, and the other fomewhat fmaller, than any of the glaffes intended to be centered by them. Then, having cleared out all the wood within the inner circle, put the end of the tube into this hole, and there fallen it with glue, fo that the bafe of the tube may lie in the furface of the board : then, having fixed the wider tube very firmly in a hole made in a window-(hutter, and having darkened the room, lay the glafs to be centered upon the board fixed to the narrower tube; and havingplaced the centre of it as nearly as you can guefs ever the centre of the hole, fix it to the board with two or three lumps of pitch, or foft cement, placed at its circumference. Then put the narrower tube in¬ to the wider as far as it can go, and fix up a fmooth fereen of white paper to receive the pi&uresof objedls that lie before the window; and when they appear di- ftinft upon the fereen, turn the inner tube round upon its axis; and if the centre of the glafs happens to be in this axis, the pi&ure will be perfe&ly at reft upon the fereen ; if not, every point of it will defcribe a circle. With a pencil mark the higheft and loweft places of any one circle, deferibed by Tome remarkable point in that part of the pifture which appears moft diftinft; and when this point of the pi&ure is brought jgg to the higheft mark, flop the circular motion of the How to tul>e> and keeping it in that pofition deprefs the coned the objeft-glafs till the point aforefaid falls exadtly in the errors. middle between the two marks. Then turn the tube round again, and the point of the pifture will either reft there, or will defcribe a much fmaller circle than before; which muft be reduced to a quiefeent point by repeating the fame operation. The centre of refrac¬ tion of the glafs will then lie in the axis of the tube, and by confequence will be equidiftant from the cir¬ cumference of the large circle deferibed upon the board fixed to it. Now to defcribe a circle upon the glafs fgh about its centre of refraftion, let a long flender plate of brafs acb hz bent fquare at each end, as re- prefented in the figure, leaving a piece in the middle equal in length to the diameter of the large circle adbe that was deferibed upon the board; and let the fquare ends of the plate be filed away, fo that a little round pin may be left in the middle of each. Then, having laid it over the glafs, along any diameter of the large circle adbe, make two holes in the board to receive the pins a and b; and find the centre of this circle upon the long plate. Then upon the centre c, defcribe a circle as large as you can, upon the glafs underneath, with a diamond-pointed compafs, and grind away all the margin as far as this circle/V^, in a deep tool for grinding eye-glaffes; and then the glafs will be truly centered. If the pitch or cement be top foft to keep the glafs from flipping, while the circle is deferibing, it may be fixed firmer with wax or harder cement.

Draw Q^, e,f, cutting the fereen in f; and while the tube is turning round, the line Q_/y will defcribe a conical furface whofe axis is the fixed line Q tf/7 and therefore the focus q, or image of the point will defertbe a circle qg x about f, to be found upon the fereen by bifefting the inter¬ val q n between the higheft and loweft points of the circle.

It is not. ne- ceffary for the accuracy of the praftice, that the point QJhould be in the axis of the glafs. For in fig. 7.

This indeed gives the metal its utmoft i whitenefs, but at the fame time renders it fo exceed¬ ingly hard, that the fined waihed emery will not cut it without breaking up its furface; and the common blue dones ufed in grinding fpecula will not touch it. With great pains, however, Mr Jackfon found a done which would work upon this metal, and was at the fame time of a texture fufficiently fine not to injure its furface; but what this done was, or where it was to be found, he would not difcover. Another very effential property in the metal for fpecula is its compaftnefs; and in this every one of thofe formerly tried was deficient; neither was Mr Mudge able to remove this defeft till after a great many experiments. Sometimes, indeed, he fays that he fucceeded in cading a fingle metal, or perhaps two Iw or three, without this imperfedion; but mod frequently he was unfuccefsful, without his being in any degree able to aflign a reafon. The pores were fo very fmall, that they were not perceptible when the metal had recei¬ ved a good face and figure upon the hones, nor till the lad and highed polilh had been given: then it fre¬ quently appeared as if duded over with millions of mi- crofcopic pores, which were exceedingly prejudicial in two refpedts; for, fird, they became in time a lodge¬ ment for a moidure which tarnifhed the furface; and, fecondly, on polilhing the fpeculum, the putty necef- farily rounded off the edges of the pores, in fuch a manner as to fpoil a great part of the metal, by the lofs of as much light and fharpnefs in the image as there were defe&ive points of refleftion in the metal; and, to add to the misfortune, this fault was not dif- covered till a great deal of pains had been taken in grinding, and even polifhing the fpeculum ; which was at once rendered ufekfs by this mortifying dif- covery. At lad Mr Mutlge was extricated from thefe diffi¬ culties by accident. Having made a great number of experiments, and entirely exhauded his copper, he re- collefted that he had fome metal which was preferved out of curiofity, and was part of one of the bells of St Andrew’s which had been recad. This he melted with a little freih tin, and, contrary to his expecta¬ tion, it turned out perfedly free from pores, and in every refpeft as fine a metal as could be defired. At fird he could not account for this fuccefs, but after¬ wards difcovered it by reflecting on the circumdances of his procefs. He had always melted the copper fird, and, when it was fufficicntly fufed, he added the pro¬ portional quantity of tin ; and as foon as the two were mixed, and the fcoria taken off, the metal was poured into the moulds. He now began to confider that putty was calcined tin, and fufpeCted that the exceffive heat which copper neceffarily tindergoes before fufion, was fufficient to reduce part of the tin to this date of calcination, which therefore might fly off from the compofition in the ftate of putty, at the 'ime the me¬ tal was poured out. On this idea he furniftied him- felf with fome more Swedilh copper and grain-tin. The former he melted as ufual, and mixed the tin a- long with it, cafling the nrtixture into an ingot. This was porous, as he had expeCkd; but after a fecond i c s. ^6I9 fufion, it became perfe&ly clofe; nor, after this, did Mechanifm he ever meet with the above-mentioned imperfedion °.f in a fingle inftance. All that is neceffary to be done, jnftrPv^e,us therefore, in order to procure a metal with the requi —- fite properties for a fpeculum, is to melt the copper and tin in the above-mentioned proportions ; then, having taken off the fcoria, cad it into an ingot. This metal mud be a fecond time melted to cad the fpecu¬ lum; but as it will fufe with a fmall heat in this com¬ pound date, it ffiould be poured off as foon as melted, giving it no more heat than is abfolutely neceffary. It mud be obferved, however, that the fame metal, by frequent melting, lofes fotnething of its hardnefs and whitenefs; when this is this cafe, it becomes neceffary to enrich that metal by the addition of a little tin, perhaps of half an ounce to a pound. And indeed, when the metal is firft made, if, indead of adding the 144- ounces of tin to the copper all at once, about an ounce of the former is referved, and added to it in the fecond melting, the compofition will be more beauti¬ ful, and the grain much finer. That the metal may have a good furface, it is neceffary, before it is poured off, to throw into the crucible a fpoonful of charcoal- dud; immediately after which the metal mud be dir- red with a wooden fpatula, and poured into the moulds- §5’ Of preparing the Moulds} Grinding., Cajling, and Polijhing, the Metal. For this purpofe Dr Smith preferibes the following method. “ Having in the fird place confidered of what length one would propofe the inftrument to be,methodof and confequently what diameter it will be neceffary to making the give to the large fpeculum, for which there are ample 8aUSes- indruftions by Sir Ifaac Newton’s table in the Philo- fophical Tranfadlions aforefaid, allowing about an inch more than the aperture in the table for the falfe figure of the edges, which very often happens; I fay, having determined thefe things, take a long pole of fir deal, or any wood, of a little more than double the length of the indrument intended, and drike through each end of it two fmall deel points, and by one of them hang up the fame againd a wall perpendicularly ; then take two pieces of thin plate-brafs well hammered, a little thicker than a fixpence; thefe may be about an inch and a half broad, and let their length be in re- fpe& of the diameter of the fpeculum as 3 to 2, viz. if the fpeculum be 8 inches diameter, thefe may be about 12. Fix each of thefe drongly with rivets be¬ tween two thin bits of wainfeot, fo that a little more than a quarter of an inch in the breadth may dand out from between the boards. Then fix up thefe pieces horizontally againd the wall under your pole ; and therewith, as with a beam compafs, drike an arch up¬ on each of them: then file each of them with a fmooth file to the arch druck, fo as one may bg a convex and the other a concave arch of the fame circle. Thefe braffes are the gauges to keep the fpeculum, and the tools on which it is ground, always to the fame fphere. And that they may be therefore perfedlh true to each o- ther, it is neceffary to grind them with fine emery one againft the other, laying them on a flat table for that purpofe, and fixing one of them to the table. 0f n “ When .he gauges are perfedly true_, let a piece the of wood be turned about 2 tenths of an inch broaderfor the fpe- than the intended fpeculum, and fomewhat thicker, colam. which 5620 OPT Mechanifm which it is bell to cad in no cafe lefs than a tenths of °( , an inch thick, and for fpecula of 6, 8, or jo inches Inftrumentsbroad, this fhould be at lead 3 or 4 tenths thick when — finilhed. This board being turned, take fome com¬ mon pewter, and mix with it about of regulus of antimony; and with that wooden pattern caft one of this pewter, which will be confiderably harder than common pewter. Let this pewter pattern be truly turned in a lathe, and examined by means of the gauges aforefaid, as a pattern for cafting the fpecula them- felves; and take care when it is turned that it be at lead -j1^ of an inch thicker, and about of an inch broader, than the fpeculum intended to be cad there¬ from. “ The manner of making the moulds for cading is now to be explained; and will ferve for a direction as well for cading this pewter pattern, as aftewards for cafting thereby the fpeculum itfelf. The flafles had bed be of iron, and mud be at lead two inches wider every way than the fpeculum intended. In each flaik there fltould be the thicknefs at lead of one inch of fand. The cafting-fand which the common founders ufe from Highgate, will do as well as any; and any fand will do which is mixed with a fmall proportion of clay to make it dick. The fand thould be as little wet as may be, and well beaten but not too hard. The ingates ihould be cut fo as to let the metal flow in, in four or five dreams, over the whole upper part of the mould ; otherwife whatever pores happen in the metal will not be fo equally difperfed as they fltould be over the whole face of the metal, thefe pores ge¬ nerally falling near the ingate dreams. Let the flafles dry in the fun for fome hours, or near a very gentle fire; otherwife they will warp, and give the fpeculum, when cad, a wrong figure. For befides faving the trouble in grinding, it is bed on many accounts to have the fpeculum cad of a true figure; and it is for this reafon, that it is bed to caft it from a hard pewter pattern, and not from a wooden one as founders ufu- ally cad.” With regard to the proper metal, opticians have been greatly at a lofs, till of late that Mr Mudge has difeovered a compofition which anfwers every purpofe I93 as well as can be expetded, and of which an account Dr Smith’s hath been already given. “ The metal being duely method of cad, the furface of it is to be ground quite bright upon rough- a cornmon grindftone ; keeping it, by means of your fheVpecu- convex g£USe> as near t^ie figure as may be. When lum. afi the outward furface and fand-holes, falfe parts, and inequalities, are ground off, then provide a good thick done; a common fmall grindftone will do very well. Let its diameter be to the diameter of the fpeculum as 6 to y : with another coarfe done and fharp fand or coarfe emery rub this done till it fits the concave gauge ; and then with water and coarfe emery at firft, and afterwards with finer, rub your fpeculum upon this done until it forms itfelf into a true portion of a fphere fitting your convex gauge. A different method of moving the metal upon the done will incline it to form itfelf fomewhat of a fmalleror larger fphere. If it be ftruck round and round, after the manner of glafs-grinders, the done will wear off at the outfides, and the metal will form itfelf into the portion of a lefs fphere. If it be ftruck crofs and crofs the middle, it will flat the done, and become fomewhat of a larger I C S. Part II fphere. There (hould be ufed but very little emery Meehai at a time, and it ought to be frequently changed ; otherwife the metal will always be of a fmaller fphere than the done, and will hardly take a true figure, efpe- cially at the outfide. For the better grinding the me¬ tal, it is neceffary, that this ftone (hould be placed firm upon a ftrong round board fixed firmly on a pod to the floor, as is ufual with glafs-grinders; and the fame table or pillar will ferve for the further grinding and polilhing the fpeculum. “ When the metal is caft and rough-figured, which (hould be done with taking off as little of the fur¬ face of the metal as pofiible, (becaufe that cruft feems generally to be harder and more folid than the inner parts) the fides and back of it (hould be fmoothed and finiftied ; left the doing that afterwards (hould make the metal caft, and fpoil the figure of the fore- fide. “ Around brafs plate mud becadoffufficientbreadthinftrumi and thicknefs (for a fpeculum of fix inches in diameter requifite* Mr Hadley ufed a brafs plate 8 or 9 inches and half an inch thick.) Let one fide be turned to the concavity you defign your fpeculum to have, on the other fide let it have fuch an handle faftened as may make it eafily manageable. This handle (hould be as (hort as conveniently it can, and be fixed to the plate’s back rather by fome other method than either by ferew- ing it into a hole in the metal, or by a broad (boulder ferewed againft the back of it, for fear of bending the plate. Have ready a round marble of about or Tr^ broader than the brafs plate, and an inch or an inch j and a quarter thick: let this be cut by a done-cutter to the fame convexity on one fide as the concavity of the plate, and then grind it with the plate and emery till all the marks of the chifel are out. This marble is to be covered with pieces of the fined blue hone or whetftone, choofing thofe that are neared of a breadth and thicknefs ; but chiefly thofe that when wetted appear mod even and uniform in their colour and grain. They are to bp cut into fquare bits; and thefe, having each one fide ground concave on the con¬ vex marble with emery or fine fand, are to be fixed Plate clofe down on it with fome tough and ftrong cement CCXXV1 in the manner of a pavement, leaving a fpace of a^S-s* fmall draw’s breadth between each ; their grain be¬ ing likewife placed in an alternate dire&ion, as repre- fented in the figure. I choofe rather to difperfe the fquares that come out of the fame whetftone, than to keep them together. They mud then be reduced to one common convex furface to fit the brafs plate.; and if the cement happen to rife any where between them, fo as to come up even with the furface, it mud be dug out; and fo, from time to time, as often as the hones wear down to it. Upon thefe fquare pieces of whetftone the lad figure is to be given to the fpe¬ culum. “ Befides thefe, there will be wanted for the lad po- lifli, either a very thick round gla|s plate, (its diameter being about the middle fize between that of the brafs tool and the fpeculum itfelf,) or if that cannot be pro¬ cured of near half an inch in thicknefs, a piece of true black marble of the evened grain and freed from white veins or threads, may do in its dead. This glafs or marble muft be figured on one fide to the brafs tool likewife, and is to ferve for iiniftiing of the poli(h of Partlll. OPT Mtrhanifm of tlie fpeculum, when covered with farctnet as fliall 1be dire died. 'Indrumen's “ ^ f««aller brafs or metal plate of the fame conca- vity with the larger will be ufeful, as well to help to reduce the figure of the hones whenever it appears to be too convex, as to ferve for-a bruifer to rub down any gritty matter happening to be amongft your put¬ ty before you put the fpeculutn on the polilher, when you renew the powder. Any of the fpeculums which prove bad in calling, will ferve for this purpofe. When all is thus far ready, let the marble with the blue hones be fixed in fuch a manner that it may be often wallied during your work, by throwing up¬ on it about half a quarter of a pint of water at a time without inconvenience. Then place the brafs tool on the hone pavement; and rub it backwards and for¬ wards with almoft a diredt motion; yet carrying it by turns a little to the right and left, fo as to go a little over the edges of the pavement every way, regularly turning the tool on its own axis, and alfochatlging the diredtion of the ftroke oh the hones. This continue, keeping them alw'ays very wet, till you have got out all the rings remaining in the plate from the turning, and the blacknefs from grinding the marble or glafs in it; and, towards the latter end, often wafhing away the mud which comes from the whetftones. When this is done, lay the brafs tool down, and in it grind again with fine emery the glafs or marble defigned for the Jaft polilher, giving it as true a figure as poffible. “ Choofe a piece of fine farcenet as free from rows and great threads as you can. Let it be three or four inches broader than the glafs or marble; and turn down the edges of the farcenet round the fides of the glafs, &c. Strain it by lacing it on the backfide as tight and fmooth as you can, having firft cleared it of all wrinkles and folds with a fmooth iron, and drawn out the knots and gouty threads. Then wet it all over as evenly as you can with a pretty ftrong foliation of common pitch in fpirit of wine; and when the fpirit is dried out, repeat the fame ; and if any bubbles or blifters appear under the farcenet, endeavour to let them out with the point.of a needle. This mull be repeated till the filkis not only ftuck every where firm¬ ly down to the glafs or marble, but is quite filled with the pitch. A large painter’s pencil, made of fquir- rel’s hair, is of ufe for fpreading this varnilh equally on the li!k, efpeeially when it begins to be full. It mud then be fet by for fome days, for the fpirit to dry well out of it, and the pitch to harden, before any thing more be done to it. If you do not care to wait fo long, the pitch may be melted into the filk without dilfolving it in fpirits. In order to this, drain a fe- cond thin filk over the fird, but you need not be cu¬ rious in the choice of it; and having heated all together as hot as you think the filk or glafs will fafely bear, pour on it a little melted pitch (fird drained through a rag) fo much as you judge fufficient to fill both filks; it mud be kept hot for fome time till the pitch feems to have fpread itfelf evenly all over. If you cannot get it to fink all into the upper filk, but it Hands above it any where, it is a lign that there was too much pitch laid on, which Ihould be taken away in thofe places while it remains liquid, with a hot rag preffed down on it. When all is cold again, drip off the outward filk, and cut away the ufekfs loofe edges ICS. 562 r of the inward. To take off the fuperflous pitch where Mechanifm it lies too thick, and reduce the whole to a regular °( furface, it mud be rubbed in the brafs tool with alittle foap and water, till they are coloured of a pretty deep brown with the pitch ; then wafh them away, and re¬ peat the fame with more foap and water, till the wea¬ ving of the filk appears every where as equally as you can make it. As this work takes up fome time, you may expedite it by putting a few drops of fpirit of wine to the foap and water (which will help them to diffolve and wear away the pitch fomewhat fader till it comes towards a conclufion ; and'if there are any places where the pitch lies very thick, you may ferape it away with a fharp knife. This polilher mud be carefully kept from all dud and grit, but particularly from emery and filings of hard metals, and therefore (hould not be ufed in the place where the others come. After they have ferved a good while, they are more apt to fleek the metals than at fird ; to prevent which, their furfaces may be taken off by rubbing them wish foap and water in the tool as before, and then driking- them over once or twice with the abovementioned folution of pitch with a pencil, proceeding as before ; only that you mud not now put any fpirit to your foap and water, nor will you- need to change them above once or twice. “ You may now begin to give the figure to your fpeculum on the hones, rubbing it and the brafs tool on them by turns, till both are all over equally bright; having fird fixed on to the middle of the back of your fpeculum a fmall and lowhandle, with only pitch drain¬ ed through a rag. For of all cements, that feems the lead apt to bend the metals in dicking thefe handles, &c. on them. rpf “ The polilher being fixed likewife in a proper man- Method off ner for your work, rub either the metal itfelf, or ra-giving the ther the before-mentioned bruifer, being fird alfo fi-PoliJh- gured on the hones, with a little putty, wafhed very fine, and fair water, till it begins to fhew fome polilh. Then if you find it takes the polilh unequally, that is,, more or lefs about the edges than in the middle, it is a fign the brafs tool and metal, &c. are more or lefs concave than to anfwer the convexity of the polilher and mud be reduced to the curvature of this, rather than to attempt an alteration in the figure of the po¬ lilher, which would be a much more difficult as well as laborious work. If the fpeculum appears too fiat, the larger brafs tool mud be worked on the hones for fome time, keeping its centre near their circumference, with a circular motion; but concluding for four or five minutes with fuch a motion as was before deferibed,. Then figure the metal anew on the hones, and try it again on the polilher as before. If the metal be too concave, the furface of the hones may be flatted by rubbing the fmaller brafs plate, or the before-mention¬ ed ill-cad metal, on the middle of them; with a diredi but ihort droke, fo as but jud to reach over their cir¬ cumference with the edge of it. Then the larger brafs is to be worked on them in the fame manner; and lad of all the metal to be polilhed. When you find the brafs tool and hones, &c. anfwer the curvature of the poliflier, you may then examine the truth of the figure of the fpeculum more dridlly, to avoid the Ipfs of time and labour in finilhing its polilh while the figure is im¬ perfect.

Thofe largeft images in this cafe will be vi- fible, (although the fpeculum have no other polifh than what the hones give it), when received on a thick white card held clofe to that edge of the plate, if the back of the card be either blacked or fo lhaded that the candle may not Ihine through it, and the eye be alfo fkreened from the candle’s diredi light. If any difficulty happens in difcerning them, the plate may be removed, and the Image of the whole flame will be eafily feen. Have ready an eye-glafs whofe focal di- flance may be fomething greater than the double of that of the eye-glafs you intend for the inftrument when finilhed: you may try feveral at your difcretion. Let this be fupported by a fmall {land moveable on the table, and capable of raifing and finking it as the height of the flame requires, and of turning it into any dire&ion. By means of this (land, bring the eye-glafs Into fuch a pofition, that the light from fome of the holes, after its refledlion from the fpeculum, may be received perpendicularly on its furface; and that its diilance from the fpeculum be fuch, that the refle&ed images of the holes may be feen diftindlly through it, near the edge of the thin plate, by the light coming im¬ mediately from the fpeculum : guide the candle and thin plate with one hand, and the ftand carrying the eye-glafs with the other, till you have got them Into fuch a fituation, that you fee difiinftly at the fame time, through the eye-glafs, the edge of the thin plate, and the image of one of the holes clofe to It. Meafure the cxa& diftance of the middle of the fpeculum from the thin plate diredliy againft the flame, and alfo from the edge clofe to which you fee the image of the hole. If thefe meafures are the fame, fet it down as the exa& radius of concavity of your fpeculum, and proper cur¬ vature for any that are to be polifhed on your poliffi- er, though that will allow fome latitude: if the mea¬ fures aforefaid differ, take the mean between them. “ You will now alfo judge of the perfe&ion of the fpherical figure of your metal by the diftindtnefs with which you fee the reprefentations of the holes, with their raggednefs, duits, and fmall hairs flicking in them; and you will be able to judge of this more ex- adtly, and likewife to difcover the particular defers of your fpeculum, by placing the eye glafs fo as to fee one of the ftnalleft holes in or near its axis; and then by fhoving the eye glafs a very little forward towards the fpeculum, and pulling it away, by turns, let¬ ting the candle and plate ftand dill in the mean time. By this means you will obferve in what manner the light from the metal comes to a point, to form the I C S. Part III Images, and opens again after It has paft It. If the Mechanp: area of the light, juft as it comes to or parts from the °.f ' point, appears not round, but oval, fquarifh, or trian- E gular, &c. it Is a fign that the fedlions of the fpecu- 1 L lar furface, through feveral diameters of it, have not the fame curvature. If the light, juft before it comes to a point, have a brighter circle round the circumfe¬ rence, and a greater darknefs near the centre, than -!1 after it has croffed and is parting again ; the furface is more curve towards the circumference, and flatter about the centre, like that of a prolate fpheroid round jl the extremities of its axis ; and the ill effects of this figure will be more fenfible when it comes to be ufed in the telefcope. But if the light appears more hazy and undefined near the edges, and brighter in the middle before its meeting than afterwards, the metal is then more curve at its centre and lefs towards the circumference ; and if it be In a proper degree, may I, probably come near the true parabolic figure. But the {kill to judge well of this, muft be acquired by obfer- vation. “ In performing the foregoing examination, the fw image muft be reflefted back as near the hole itfelf as the eye’s approach to the candle will admit of, that ■ the obliquity of the reflexion may not occafion any fenfible errors: in order to which, the eye (hould be Ikreened from the candle; and the glaring light, which may difturb the obfervation, may be ftill more effeftu- 4 ally fhut out, by placing a plate, with a fmall hole in 4 it, in that focus of the eye- glafs which is next the eye. A is the fpeculum, B the candle and plate with the Fig- >•->* fmall holes, C the cell with the eye-glafs and plate be¬ hind it. “ Inftead of the flame of the candle and plate with fmall holes, 1 fometimes made ufe of a piece of glaf* thick ftuck with globules of quickfilver,{trained thro' a leather, and allowed to fall on it in a dew; placing this glafs near a window, and the fpeculum at a diftance on the fide of the room, being itfelf and every thing a- bout it as much in the dark as can be. The light of the window reflected from the globules of mercury, 1 appearing as fo many ftars, ferves inftead of the fmall holes, with this advantage, that the refledlion from the metal may be very near at right angles. 197 J “ If the figure of the metal appears not fatisfa&o-9f corrccfl ry, the hones muft be worked with the brafs tool and tln2 thc water for 2 or 3 minutes with the motion, &c. firftrorS* dire&ed; then work the metal on them with the like I motion, and fuch length of the flroke as may carry the edge of it about or I; of its diameter beyond that 1 of the hone pavement each way; carry it likewife by turns to the right and left, to about the fame diftance. Continue this about 5 minutes, not preffing the metal down to the hones with any more than its own weight, and obferve that the oftener the mud is wafhed away, the more truly fpherical the figure of the fpeculum will generally be: but the leaving a little more of this mud on the Hones has fometimes feemed to give the metal a parabolic figure. I have likewife given it the fame, by concluding with a kind of fpiral motion of 11 the centre of the metal, near the circumference of the hones, in the manner reprefented in fig. 11. for about half a minute. “ If after feveral trials the metal appears to have always the fame kind of defedt, and anfwering to the fame Part III. OPT Mechatiifm fame particular part of tbe metal, it is a fign of a dif- j§ ■ ferent hardnefs in its feveral parts, which will make it Inftrumentsvery to bring that fpeculum to perfeftion. In working the tools or metals on the hones, there will often appear little fpots in them, much blacker and harder than the reft ; thefe muft be dug out as fall; as they appear. “ When the figure is to your mind, you may pro¬ ceed to finifh the polilh on the farcenet with very little putty, and that diluted with a great deal of water. Before you put the putty and water on it, obferve, by holding it very obliquely between your eyes and the light, if it have any lifts or ftripes acrofs it, which appear more glofly than the reft. If it be fo, let the motion of the metal in polifhing be direflly athwart thefe lifts, and not along with them, nor even circu¬ lar. In other refpe6ts you may obferve the fame direc¬ tions as were before given for its motion on the hones; not forgetting, after every 15 or 20 ftrokes, to turn it on its axis about -jV or of a revolution. As the polifher grows dry, you will find the metal flick to it more and more ft iff; at which time it both polifties fafter and with a better glofs: only take care that it grows not fo dry as for the metal to take hold of the farcenet and cut it up, or for the pitch and putty to fix in little knobs here and there on it; which, if it happen, will prefently fpoil the figure. As fall there¬ fore as the farcenet appears to be growing dry at any of its edges, touch the place with the end of a fea¬ ther dipped in clean water: you may ufe the fame putty at leaft half an hour. As often as you change it, wafh the old clean away, and rub the new about firft with your bruifer, to fee if there be any gritty or grofs particles in it, and rub them away for fear of fcratching the metal ; then laying down the edge of the fpeculum a little way on the edge of the polilher, where it is well covered with water, Aide it on the middle, and then proceed. The lefs putty you ufe at a time, the flower the work will advance ; but if you ufe too much, it will fpoil a little of tbe figure round the edges. It will not want any confiderable force to prefs it down ; but if it be of 5 or 6 inches diameter or more, it will be very laborious to go through the polifh without fome kind of machine.” Mr Mudge is of opinion that all this troublefome method is entirely unneceffary, and of the fame opi¬ nion is an anonymous French author who wrote on this fubjedt in the year 1738. The latter tells us what is certainly agreeable to reafon and experience, that the more complicated the machines are by which we attempt to accomplifh any purpofe, the more liable we are to error by r’afon of their perpetual ten¬ dency to go wrong, and the neceffary multiplication of inaccuracy is a complicated motion. Four tools, according to Mr Mudge, are all that are neceffary; viz. the rough grinder to work off the rough face of the metal; a brafs convex grinder, on which the metal is to receive its fpherical figure ; a bed of hones, which is to perfeft that figure, and to give the metal its fmooth fine face ; and a concave tool or bruifer, with which both the brafs grinder and the hones are to be formed. A poliftter may be confidered as an additional tool ; but as the brafs grinder is ufed for this purpofe, and its pitchy furface is expeditioufly ‘ and without difficulty formed by the bruifer, the ap- Vol. VIII. i I C S. 5623 paratus is therefore not enlarged.

This leaden tool being call, it being fixed in the lathe, and turned as true as poffible by the gauge to the figure of the intended fpeculum, making a hole or pit in the middle for a lodgement to the emery, of four inches ; when this is done, deep grooves muft be cut acrofs its furface with a graver, as is reprefented fig. 7. TLefe grooves will ferve t0J;lavvvm lodge the emery, and by their means the tool will cut^ a great deal fafter. There is no reafon to fear any al¬ teration in the convexity of this tool by working the metal upon it; for the emery will bed itfelf in the lead, and fo far arm the furface of it, that it will pre- ferve its figure, and cut the metal very faft. Any kind of low handle, fixed on the back of the metal, with foft cement, will be fufficient; but it ftiould cover two thirds of its back, to prevent its bending. “ This way of working (fays Mr Mudge) will cut the metal fafter, and with more truth, than the me¬ thod deferibed by Dr Smith ; for fhould the furface and rough parts be attempted to be ground off by a common grindftone by hand, though you did it as near the gauge as poffible, yet the metal would be fo much out of truth when applied to the fucceding tool, that no time would be faved by it.” For this purpofe Mr Mudge ufed to employ a common labourer, who foon acquired fuch dexterity at working upon the tool, that in two hours time he would give a metal of four inches dimeter fo good a face and figure as even to fit it for the hones. When all the fand-holes and irregularities on the face of the metal are ground off, and the whole furface is fmooth and regularly figured, the fpeculum is then ready for the brafs grinder, and muft be laid afide for the prefent. ijj, The brafs grinding-tool is formed in the following Manner of ' manner. Procure around flout piece of Hamburgh brafs, at rrioft a fixth part larger than the metal to be ing-tooZ" poliffied; and let it be well hammered, by the affiftance of the gauge, into a degree of convexity fuitable to the intended fpeculum. Having done this, ferape and clean the concave fide fo thoroughly, that it may be well tinned all over ; than call upon it, after it has been preffed a proper depth into the fand, the compofition of tin and lead above-mentioned, in fuch quantity, that it may, for a fpeculum of four inches diameter, be at leaft an inch and half thick, and with a bafe confiderably broader than the top, in order that it may ftand firmly upon the bench hereafter to be deferibed. This being done, it muft be fixed and turned in the lathe with great care, and of fuch a con¬ vexity as exadliy to fuit the concave gauge. More care will be neceffary in forming this tool than the former, efpecially that no rings be left in turning ; nor will the fucceeding hone-tool require fo much ex- adlnefs, as any defedts in turning will, by a method hereafter mentioned, be eafily removed ; but any in¬ equality or wanUof truth in the brafs tool will occa- OPT Mechanifm fion a great deal of troble before it can be ground out „ . , by the emery. This tool mull have a hole, fomewhat Optical , V ^ .v. .-i :* InarPumentslefs that in the metal to be worked upon it, in — the middle, quite through to the bottom. When this tool is finilhed off in the lathe, its diameter fliould be aoo one-eighth wider than the metal. The hones Ihould be of the beft fort of thofe re- I C S. Part mm every now and then, (hift your own pofition, by Mechani^iu walking round, and working at different fides of the °f .Kc Krafc tool • at timpe tVi<» ftrolre (VinnM Kp ronnrl . t^Tof 6 commended by Dr Smith. They fhould be cemented hones. in fmall pieces (in a kind of pavement, as hath been already mentioned) upon a thick round piece of mar¬ ble, or metal made of lead and tin in the proportions above diredted, in fuch a manner, that the lines be¬ tween the ftqnes may run ftraight from ope end to the other; fo that placing the teeth of a fine faw in each of thefc divisions, they may be cleared from one end to the other of the cement which rifes between the ftones. This bed of hones fhould be at lead one- fourth larger than the metal which is to be ground upon it ; but there i$ no neceflity for turning the me¬ tal on which the hones are cemented tq the fame con¬ vexity with the gaugje. As foon as the hones are cemented down, and the joints cleared by the faw, this tool mull be fixed in the lathe, and turned as exadlly true to the gauge as pofiible ; which done, it muft be laid afide for the prefent. The next tool to a or be made is the bruifer. Manner of The broiler fhquld be made of thick flout brafs like brutfcrgthe^h? former, perfe&ly found, about a quarter of an inch thick, and hammered as near to the g?uge as poffible. It fhould then be ferpped, cleaned, and tinned on the convex fide, as the former tool was on the concave, and the fame thickqefs of lead and tin cafl upon it. The general fhape of this fhould differ from the for¬ mer ; for as that increafed in diameter at thg bottoiq for the fake of (landing firmly, fo this fhould be only as broad at bpltorp as at top, as it is to be ufed oc- cafionally in both thofe pofitions. When this tool is fixed in the lathe, and turned off concave to the convex gauge with great truth likewife, its diameter ought tq be the middle fixe between the hones and the po- lifiier. Having with the lathe roughly formed the convex brafs grinder, the bed of hones, and the concave bruifers, the convex and concave brafs tqqls and the metal muft be wrought alternately and reciprocally upon each other with fine emery and water, fo as to keep them as nearely to the fame figure as poffible; in order to yrhich, fome wafhed emery muft be pro¬ cured. This is beft done by putting it into a vial, which muft be half filled with water and well fhaken up, fo that, as it fnbfixles, the coarfeft may fall to the bottom firft, and the fined remain at the top; and whenever frefh emery is laid upon the tools, the beft method (which we fhould alfo obferve with the putty in palifhing) will be, to fhake gently the bottle, and act pour opt a (mail quantity of the turbid mixture. Of grinding The tp0|3 being n.ow all, ready, upon a firm poft in lum^the" t^ie of a room, you are to begin to grind the brafs tool, -brafs convex tool witli the bruifer upon it, working and the the latter croffwife, with ftrpkes fo.metimes actofs its brmfer, to- diameter, at others a little to the right and left, and ge.her. always fo ftiort, that the bruifers may not pafs above half an inch within the furface of the brafs tool, either way, fhifting the bruifer round its axis every half dozen firokes or thereabout. Yqu muft likewife, brafs tool: at times the ftroke fhould be carried round inftrrUmenH and round, but not much over the tool: in fhort, 3| they muft be dire&ed in fuch a manner, and with fuch equability, that every part of both tools may wear equally. This habit of grinding, as well as the future one of polifhing, will foon be aquired. When you have wrought m this manner about a quarter of an hour with the bruifer upon the tool, it will be then neceffary to change them, and, placing the bruifer upon its bottom, to work the convex tool upon that in the fame manner. When, by working in this equable manner alternate¬ ly with the bruifer and tool, and occafionally adding frefh emery, you have nearly got out all the veftiges of the turning tool, and brought them both nearly to a figure, it will then be time to give the fame form to the metal. This muft be doire by now and then grinding it upon the brafs topi with the fame kind qf emery; taking care, however, by working the two former tools frequently together, to keep all three exaflly in the fame curve. The beft kind of handle for the metal is made of lead, a little more than double its thicknefs, and fomewhat lefs in diameter, of about three ppqnds weight, with a hole in the middle, (for reafons to be afterwards fhown), a little larger than that in the metal: this handle fhould be cemented on with pitch. The upper edge of this weight fhould be rounded off, that the fingers may not be hurt; and a groove about the bignefs of a little finger be turned round juft below it, for the more cqnveniently holding and taking the metal off the tools. When the bruifer, brafs tpol, and metal, are all Manner brought to the fame figure, and have all a true goodfiguring furface, the next part of the procefs is to give a cor- reA fphericsl figure and a fine face to the metal upon the hones, {t is neceffary to obferve, however, that the hones fhould be placed in a veffel pf water, with which they fhould be quite covered for at leaft an hour be¬ fore they are ufed ;^otherwife they will be continually altering their figure when the metal comes to be ground upon them. The fame precaution is alfo neceffary if you are called off from the work while you are grind¬ ing the metal; for, if they be fuffered to grow dry, the fame inconvenience will enfue. In order to give a proper figure to the hones, and exa&ly fuitableto that of the brafs tool, bruifer, and metal, when the hones are fixed down to the block, fome common flqur emery (unwa(hed),withagood deal of wa¬ ter, muft be put upon them, and the bruifer being placed upon the hones and rubbed thereon with a few ftrokes and a light hand, the inequalities of the done will be quickly worn off; but, as a great deal of mud will be fuddeoly generated, it muft be wafhed off every quar¬ ter of a minute with plenty of water. By a repeti¬ tion of this two or three times, the hones (being of a very foft and friable nature) will be cut down, to the figure without wearing or altering the bruifer at all. Tho* this bufinefs may be qqickly done, and can be continued but for a few ftr.okes at a time, it is abso¬ lutely neceffary that thofe ftrokes be carried in the fame dire&ion, and with the fame care, which was ob- ferved in grinding the former tools together. As i PartlH. OPT I Mecharif'm As foon as the hones have received the general fi- W . gure of the bruifer, and all the turning ftrokes are ii flirtnimentsworn out ^rom t*iem> t^ie emery muft be carefully Jj wafhed off; in order to which, it will be neceflary to clear it from the joints with a brufh, under a ftreamof water. The bruifer and metal mud likewife be cleared in the fame manner, and with equal care, from any lurking particles of emery. The hones being fixed down upon the block, you now begin to work the bruifer upon them with very cautious, regular, fhort ftrokes, forward and back¬ ward, to the right and left, turning the axis of the bruifer in the hand, while you move round the hones by fhifting your pofition, and walking round the block. The whole now depends upon a knack in working, which fhould be condu&ed nearly in the fol¬ lowing manner. Having placed the bruifer on the centre of the hones, Aide it in an equable manner for¬ ward and backward, with a ftroke or two direftly acrofs the diameter, a little on one fide, and fo on the other. Then, fhifting your pofition an eighth part round the block, and having turned the bruifer in your hand about as much, give it a ftroke or two round and round, but not far over the edges of the hones, and then repeat the crofs-ftrokes as before: thofe round ftrokes, which ought not to be above two or three at moft, are given every time you fhift your own pofition and that of the metals previous to the crofs ones, in order to take out any ftripes, either in the hones or bruifer, which may be fuppofed to be occafioned by the ftraight crofs ftrokes. During the time of work¬ ing, no mud muft be fuffered to colledf upon the hones, fo as to deftroy the perfeft contact between the two tools ; and therefore they muft every now and then be wafhed clean by throwing fome water upon them. When, by working in this manner, all the emery ftrokes are ground off from the bruifef, and it lias acquired a good figure and clean furface, you may then begin with the metal upon the hones, in the fame cautious manner, wafhing off the mud as faff as it col- lefts ; though that will be much lefs now than when the bruifer was ground upon them. Every now and then, however, the bruifer muft be rubbed gently and lightly upon the hones, which will, as it were, by fharpening them, and preventing too great fmoothnefs, occafion them to cut the metal fatter. After having, by working in this manner, taken out all the emery ftrokes, and given a fine face and true figure to the metal, which will be pretty well known by the great equality there is in the feel while you are working, and by which an experienced work¬ man will form a pretty certain judgement, you may then try your metal, and judge of its figure by the following more certain method. Wafh the hone pavement quite clean ; then put the metal upon the centre of it, and give two or three ftrokes round and round only, not carrying, however, the edges of the metal much over the hones; this will take out the order of ftraight ftrokes : then, ha- ving again walhed the hones, and placed the fpeculum upon their centre, with gentle preffure. Aide it to¬ wards you, till its edge be brought a little over that of the hones; then carry it quite acrofs the diameter as far on the other fide, and having given the metal a light ftroke or two in this direftion, take it off the I C S. 5625 tool. The metal being wiped quite dry, place it up- Mechaniftn; on a table at a little diftance from a window; {land °f . yourfelf as near the window, at fome diftance from the rnfifumeuts metal, and looking obliquely on its furface, turn it - round its axis, and you will fee at every half turn the grain given by the laft crofs ftrokes flaAi upon your eye at once over the whole furface of the metal. This, fays Mr Mudge, is as certain a proof of a true fpherical fi¬ gure, as the operofe and difficult method defcribed by Dr Smith: for as there is nothing foft or elaflic either in the metal, or in the hones, this glare is a certain proof of a perfsft contaft in every part of the two fur- faces ; which there could not be, if the fpheres were not both perfeft and precifely the fame. Indeed there is one accidental circumftance which affords its aid in this and other fimilar cafes; namely, that a con¬ cave and convex furface ground together, though ever fo irregular at firft, (will, if the working be uniform and proper, confifting, efpecially at laft, of crofs ftrokes in every poffible direftion acrofs the diameter) be formed into portions of true and equal fpheres. Had it not been for this lucky neceffity, it would have been impoffible to have produced that correftnefs which is effential in the fpeculum of a good refiefting telefcope by any mechanical contrivance whatever. For when it is confidered, that the errors in refleftion are four times as great as in refraftion, and that the leaft defeft in figure is magnified by the powers of the inftrument, any thing fhort of perfeftion in the figure of the fpeculum would be evidently perceived by the want of diftinftnefs in the performance. Here, however, Mr Mudge obferves, that he all along fuppofes, both in forming the tools, and at lafl in figuring the metal (and the fame is to be obferved in the future procefsof polifhing), that no kind of pref- fure is ufed that may endanger the bending or irregu¬ larly grinding them : they fhould therefore be held with a light hand, and loofely between the fingers; and the motion given (hould be in a horizontal di¬ reftion, with no other preffure than their own dead weight. Having now finiftied the metal on the hones, and rendered it both in point of figure and furface fit for the laft and moft effential part of the procefs, viz. that of polifhing, we fhall now proceed to defcribe it as minutely as poffible, though many little circumftances muft neceffarily be omitted, and can only be fupplied by experience. 204 The polifhing of the fpeculum is the moft difficult Of the po- and effential part of the procefs; and every experienced workman knows, to his vexation, that the moft tri-05" fling error here will be fufficient to fpoil the figure of his metal, and render all his preceding caution ufe- lefs. On this occafion alfo Mr Mudge makes the following remarks on the method of polifhing ufed by Hadley and Molyneux, and already defcribed from Dr Smith’s Optics. “ Firft then, fays he, the tool it- felf ufed by them in polifhing the metal is formed with infinite difficulty. The firft defcribed polifher is di¬ rected to be made by covering the tool with farcenet, which is to be faturated with a folution of pitch in fpirit of wine, by fucceffive applications of it with a brufli, till it is covered, and by the evaporation of the fpirit of wine filled with this extraft of pitch ; the furface is then to be worked down and finiihed with 31 T z the 5626 OPT Mcchaniim the bruifer. This is all very eafy in imagination; but ‘K . whoever has ufed this method (which I have myfelf, InArumu!tslul^ucce^(u"y> ^evera' times) muil have found it at- -r— tended with infinite labour, and at laft the bufmefs done in a very unfatisfadory manner; for the pitch by this procefs will be deprived of an eflential part of itscompofition. The fpirit of wine diffolves none but the refinous parts of its fubflance, which is hard and untradable ; and if you ufe foap or fpirit of wine to foftes or difTolve it, it will equally affe£t the whole fur- face, the lower as well as the higher parts of it. And fuppofe that, with infinite labour with the bruifer, it is at lail reduced to a fine uniform furface, it is never- thelefs too hard ever to give a good polifh with that Inftre which is always feen in good metals. Nor will it give a good fpherical figure : for a perfed fphere is formed, as I obferved before, by that intimate accom¬ modation'arifing from the wear and yielding of both tool and metal; whereas, in this method there isfuch a ftubbornnefs in the polifher, that the figure of the metal, whether good or bad, mull depend upon the truth of the former, which is very feldom perfed. “ If the polifher be made in the fecond manner pro- pofed, viz. by {training the pitch through an outer covering, which is afterwards to be ftripped off, the fuperficies of pitch and farcenet is fo very thin, that the putty working into them forms a furface hard and untradable, fo that it is irapoffible to give the fpecu'- lum a fine polifh. Accordingly all thofe metals which are wrought in this way have an order of fcratches in- ftead of polifh, difcovering itfelf by a greyifh vifible furface. Befides, fuppofing this tool perfedly finifh- cd, and anfwering its purpofe ever fo well, it is im- poffible that it can produce in the fpeculum any other than a fpherical figure ; and indeed nothing elfe is expeded from this method, as is evident from the ex¬ periment recommended to afcertain the truth of it. You are direded to place a fmall luminous objedf in the centre of the fphere of which the metal is a feg- ment; and then having adjufted an eye-glafs at the diftance of its own focal length from the objed, and fo lituated that the image of the objed formed by the fpeculum may be vifible to the eye, you are to judge of the perfed figure of the metal by the fharp- nefs and diftindnefs with which the image appears. 'From hence it is very evident, that as the objed and image are both diftant from the metal by exadly its radius, nothing but a true fpherical figure of the fpe¬ culum can produce a {harp and diftind image ; and that the image could not be diftind if the figure of the fpeculum were parabolic. Confequently, if the fame fpeculum ufed in a telefcope were to receive pa¬ rallel rays, there would neceffarily be a confiderable aberration produced, and a confequent imperfedion in the image. Accordingly, there never was a good telefcope made in this manner; for if the number of degrees, or the portion of the fphere of which the great metal is a part, were as confiderable as it ought to be, the inftrument would bear but a verylow charge, unlcfs a great part of the circumference of the metal were cut off by an aperture, and the ill effeds of the aberration by that means in fome meafure prevented. “ If ever a finiftied metal turned out without this defed, and has been found perfedly iharp and diftind, ,t muft have, been owing to an accidental parabolic I C S. Part nr. tendency, noways the natural refult of the procefs, and Meelianifi therefore quite unexpeded, and moft probably un- °f known to the workman.” Tnftrumenf Our author next acquaints us, that, from obferving- the high polifti of fome of the metals made by Mr Short, and concluding that the high luftre of the polifli could never have been produced in the manner above deferibed, but by fome more foft and tender fubftance, he was direded to make ufe of pitch itfelf, efpecially as Sir Ifaac Newton mentions his having ufed that fubftance in his operations. Accordingly, ftiortening Dr Smith’s procefs, he made a fet of tools in the manner above-mentioned, except that he was obliged to make fome fubfequent alteration in the polifher. Having given a good fpherical figure to the brafs tool and the bruifer, and likewife to the metal upon the hones, and made the brafs convex tool fo hot as juft not to hurt the finger, he tied a lump of common pitch, which {hould neither be too hard nor » too foft, in a rag, and holding it in a pair of tongs over a ftill fire where there was no rifing duft, till it was ready to ftrain through the linen, he caufed it to drop on the feveral parts of the convex tool, till he fup- pofed it would cover the whole furface to about twice the thicknefs of a {hilling; then fpreading the pitch as equally as he could, he fuffered the polijher (the name he gives to the tool fo prepared) to grow quite cold. He then made the bruifer fo hot as almoft to burn his fingers; and having fixed it to the bench with its face upwards, he fuddenly placed the poliftier upon it, and quickly Aid it off; by this means ren¬ dering the furface of the pitch fomewhat more equal. The pitch is then to be wiped off from the bruifer with a little tow; and by touching the furface with a tallow candle, apd wiping it a fecond time, it will then be perfeflly clean, and fit for a fecond pro¬ cefs of the fame fort, which muft again be performed as quickly as poffible; and this is ordinarily fufficient to give a general figure to the furface of the pitch. The bruifer and the poliftier are then fuffered to grow perfeftly cold; when the pitch, confidering what has been taken off, will be about the thicknefs of a {hilling. Here, however, it is neceffary to obferve, that the pitch lhould neither be very hard and refinous, nor too foft: if the former, it will be fo untradable as not to work kindly; and if too foft, it will in work¬ ing alter its figure fafter than the metal, and too readily fit itfelf to the irregularity of its figure, if it have any. When both tools are perfedly cold, he gave the poliftier a gentle warmth, and then fixed the bruifer to the block with its face upwards; and (ha¬ ving, with a large camel’s-hair brufti, fpread over the face of the poliftier a little water and foap to prevent fticking, with ftiort, ftraight, and round ftrokes, be worked it uporr the bruifer, every now and then add¬ ing a little more water and foap, till the pitch upon the poliftier. had a fine furface and the true form of the bruifer; and this he continued till they both grew perfedly cold together: in this manner the polifher was formed in about a quarter of an hour. But here a difficulty arofe. For when he began to polifh the metal, he found that the edge of the hole in the fpe¬ culum colleded the pitch towards the middle of the poliffier:. hence, though in this method of working b Part III. OPT ikechanifm he could give an exquifite poli/li, as the putty lodged 1 °( . itfelf in the pitch exceedingly well, yet the figure of llftiu'ments^1C meta' was injured in the middle; nor indeed did |I— the work go on with that equability which is the in- I feparable attendant on a good figure, la order to obviate this difficulty, he call fome metals with a con¬ tinued face, the holes not going quite through, within perhaps the thicknefs of a fixpence. In this way he iinifhed two or three metals, and the work went on very well; but when he came to open the holes, even though the utmoft caution was ufed, the metals were found to be imperfeid. This he attributed to an al¬ teration of the figure from the removal of even that fmall portion of metal after the fpeculum had been finifhed. This he fuppofes to have been the caufe of his fpoiling a very diftindl and perfedt two-foot metal, which bore a charge of 200 times, only by opening the (harp part of the edge of the hole, becaufe he thought that it bounded the field: fo efientially ne- ceflary is an exquifite corredtnefs of figure in the fpe¬ culum of a perfedt refledtor. This experiment not fucceeding, inftead of calling the metal without a hole, he made one quite through I . the middle~of the polifher, a little lefs than that in the fpeculum. This perfedtly anfwered the purpofe; no more inconvenience arofe from the gathering of the pitch, for it had now no greater tendency to colledt at the centre than the fides; and thus he finiihed feveral metals fucceffively, excellent both in figure and polifh. One of thefe, of 2 inches diameter and 7.5 focal length, bore a charge of 60 times and upwards. In this method of working, the poliihing goes on in an agreeable, uniform, and fmooth manner; and the fmall degree of yielding in the pitch, which is adtually not more than the wearing of the metal, produces that mutual accommodation of furfaces fo neceifary to a true figure. In the beginning of the poliih, and indeed for fome time during the progrefs of it, {always remembering now and then to move the metal round its axis), he worked round and round, not far from, and always equally diftant from, the ir: centre; except that every time, previous to the fiiifting the metal on its axis, he ufed a crofs ftroke or two; and when the polifh was nearly completed, he ufed moftly crofs ftrokes, giving a round ftroke or two likewife every time he turned the metal on its axis. In this method of working, he always obferved that the metal poliihed fafteft in the middle ; infomuch that one half or two thirds of it would be completely, polifhed, when the circumference was fcarcely touched by the tool. Obferving this in fome of the firlt me¬ tals, and not confidering that this way of polifhing was in faft a fpecies of grinding, and as perfedt as that upon the hones, he went on reludlantly with the work, almoft defpairing of being able to produce a good figure. However, he was always agreeably difap- pointed; for when the polifh was extended to the edge, or within a tenth of an inch of it, he almoft conftantly found the figure good, and the performance of the metal very diftindt. But this fame circumftance of apparent defedt in the metals,, was in fadt that to which their*perfediion was owing; for they all, con¬ trary to his expedlatiop, turned out parabolic. On the other hand, when he chanced to find that a metal, when firft applied to the poiilher, took the polifh I C S. 5627 equally all over, and confeqDently the bufinefs didMechanifin not take up above 10 minutes; yet the metal con- flantly turned out good for nothing. From frequent fnftrum*nts obfervations, however, he at laft found a method of giving a corredt parabolic figure and an exquifite polifh at the fame time. 10J In polifhing the fpecolum, in order to avoid the in-How to po- trufion of any particles of emery, it would not be right li[h the fPe" to polifh in the fame room where the metal and toolscu^um‘ were ground, nor in the fame cloths which were worn in the former procefs; at leaf! it would be neceflary to keep the bench quite wet, to prevent any dull from rifing. Having then made the polifher, by coating the brafs convex tool equally with pitch, which we fuppofc fmoothed and finifhed with the brafs tool in the man¬ ner before deferibed, and which is a very eafy procefs, the whole operation is begun and finifhed in the fol¬ lowing manner. The leaden weight, or handle, upon the back of the metal, fhould be divided into eight parts, by fo many deep ftrokes of a graver upon the upper furface of the lead, marking each ftroke with the numbers 1, 2, 3, 4, and fo on, that the turns of the metal in the hand may be known to be uniform and regular. To prevent any mifehief from coarfe particles of putty, it muft be wafhed immediately before ufing. In order to this, put about half an ounce of putty into an ounce phial, and fill it two-thirds with water; then having ftiaken the whole, let the putty fubfide, and flop the bottle with a cork. In a tea-cup with a little water, there fhould be a full-fized camel’s-hair brufh, and a piece of dry clean foap in a galley-pot: a foft piece of fponge will alfo be neceflary. Thefe, as well as the metal bruifer and polifher, fhould be con^antly covered from dull. The polifher being fixed down, and the camel’s-hair brufh being firft wetted and rubbed a little over the foap, let every part of the tool be brufhed over there¬ with; then work the bruifer with fhort, ftraight, and round ftrokes, lightly upon the tool, and continue to do fo, now and then turning it, till the polifher have a good face, and be fit for the metal. Then having fhaken up the putty in the phial, and touched the po¬ lifher in five or fix places with the cork wetted with that and the water, place the bruifer upon the toolr. and give a few ftrokes upon the putty to rub down any gritty particles; after which, having removed it,, work the metal lightly upon the polifher round and round, carrying the edges of the fpeculum, however, not quite half an inch over the edge of the tool, and now and then with a crofs ftroke. The firft putty,, and indeed all the fucceeding ap¬ plications of it, fhould be wrought with a confiderable while: for if time be not given for the putty to bed itfelf in the pitch, and any quantity of it lie loofe up¬ on the polifher, it will accumulate into knobs, which will injure the figure of the metal ; and therefore as often as ever fuch knobs arile, they muft be carefully feraped off with the point of a penknife, and the loofe fluff taken away with the brufh. After the putty is well wrought into the pitch, fome more may be added in the fame manner, but never much at a time; and always remembering to work upon it firft with the bruifer, for fear any gritty particles may find their way irpom 5628 OPT Mcchanifm upon the polifher. If the bruifer be apt to ftick, and °.f du not Aide fmoothly upon the pitch, the furface of 1 ftrumcmseither to°^ may be occafionaily brufhed over with the _i foap and water, but it muft be remembered that the wet brufli muft be but lightly rubbed upon the foap. In the beginning of this procefs little effeffc is pro¬ duced, and the metal does not feem to polifh faft, in fome meafure owing to its taking the polilh in the middle, andf perhaps becaufe neither that nor the brui¬ fer move evenly upon the polifher: but a little perfe- verance will bring the whole into a good temper of working; and, when the pitch is well defended by the coating of the putty, the procefs will advance apace, and the former acquiring poflibly fome little warmth, the metal moves more agreeably over it, with an uni¬ form and regular fridlion. All this while the metal muft have no more prcffure than that which it derives from its own weight and that of the handle ; and the polifher muft never be fufftred to grow dry, but, as often as it has any tendency to do fo, the edges of it muft be moiftened with the hair-pencil; and now and then, even when frefh putty is not laid on, the furface of the polifher fhould be touched with the brttfh to keep it moift. When the polifh of the metal nearly reaches the edge (for it always, as we fatd before, begins in the middle) you muft alter your method of working; for now the round ftrokes muft be gradually altered for the fhort and ftraight ones. Suppofing then you are juft be¬ ginning to alter them; after having put on frefh putty, and gently rubbed it with two or three ftrokes of the bruifer, you place the metal on the tool, and after a ftroke or two round and round, give it a few forward and backward, and from fide to fide, but with the edges very little over the tool; then having turned the metal one-eighth round in your hand, and having mo¬ ved yourfelf as much round the block (which muft be remembered throughout the whole procefs) you go on again with a ftroke or two round, to lead you only to the crofs ftrokes, which are now to be principally ufed, and with more boldnefs. After this has been done fome time, the metal will begin to move ftifly as the fridlion now increafes, and the fpeculum polifhes very beautifully and faft; and the whole furface of the po- bfhing tool will be equally covered with a fine metal¬ lic Bronze. The tool, even now, muft not be fuffered to become dry; a fingle round ftroke in each of your fiat ions and turnings of the metal will be fufficient, and the reft muft all be crofs ones, for we are comple¬ ting a circular figure. You muft now be very diligent; for the polifher drying, and the frkftion increafing very faft, the bufinefs of the fpherical figure is nearly at an end. As the metal wears much, its furface muft be now and then cleaned, with a piece of (hammy leather, from the black fluff which colle&s upon it; and the polifher likevvife from the fame matter, with a foft piece of wet fponge. You will now be able to judge of the perfed fpherical figure of the metal and tool, when there is a perfed correfpondence between the furfaces, by the fine equable feel there is in working, which is totally free from all j.rks and inequalitiw. Having proceeded thus far, you may put the laft fi- rifnlng to this figure of the metal by bold crofs ftrokes, only three or four in the diredions of each of the eight diameters, turning the metal at the. fame time: this I C S. Part lit muft be done quickly; for it ought, in this part of the Mcchanj procefs particularly, to be remembered, that, if you permit the tool to grow quite dry, you will never be ic(irum^ able, with all your force, to feparate that and the me- i tal, without deflroying the polifher by heat. The metal has now a beautiful polifh and a true ; fpherical figure, but will by no means make a (harp diftind image in the telefcope: for the fpeculum (if it be tried in the manner hereafter recommended) will not be found to make parallel rays converge without ; great aberration; indeed the deviation will be fo great, as to be vtry fenfibly perceived by a great indiftind- nefs in the image. ioS ; | In order then to give the fpeculum the laft and fi- Howto) 1 nifhing figure, which is done by a few ftrokes, it muft *hc para) be particularly remarked, that by working the metal round and round, the fphere of the polifher by this means growing lefs, it wears fafteft in the middle: and as a fegment of a fphere may become parabolic, by opening the extremes gradually from within outwards, fo it may be equally well done by increafing the cur¬ vature in the middle, in a certain ratio, from without i 1 inwards. Suppofing then the metal to be now truly fpherical, flop the hole in the polifher, by forcing a cork into it underneath, about an inch, fo that it do not reach quite to the furface; and having wafhed off any mud that may be on the furface of the tool with a wet foft ' piece of fponge, whilft the furface of it is a little moift, place the centre of the metal upon the middle of the polifher; then having, with the wet brufh, lodged as much water round the edge of the metal as the pro¬ jecting edge will hold, fill the hole of the metal and its handle with water, to prevent the evaporation of the moifture, and the confequent adhefion between the fpeculum and polifher, and let the whole reft in this : ftate two or three hours: this will produce an inti¬ mate contafl between the two, and by parting with any degree of warmth they may have acquired by the vicinity of the operator, they will grow perfe&ly cold together. By this time you may pufh out the cork from the polifher, to difeharge the water, and give the metal the parabolic figure in the following manner. Move the metal, gently and flowly at firft, a very little round the centre of the *polifher (indeed after this reft it will move ftifly); then increafing by degrees the diameter of thefe ftrokes, and turning the metal fre¬ quently round its axis, give it a larger circular motion, and this without any preffure but its own weight, and holding it loofely between the fingers: this manner of working may fafely be continued about two minutes, moving yourfelf as ufual round the block, and carry¬ ing the round ftrokes in their increafed and largeft ftate, not more than will move the edge of the mCtal half an inch or five-eighths over the tool. The fpe¬ culum muft not all this while be taken off from the poliiher; and confequently no frefh putty can be added. It will not be fafe to continue this motion longer than the time above mentioned; for if the parabolic ten¬ dency be carried the lead too far, it will be impoffible to recover a true figure of that kind but by going through the whole procefs for the fpherical'One1 in the manner before deferibed, by the crofs ftrokes upon the polifher, which takes a great deal of time. However, when Martin. OPT tbanifm when there is occafion, it may be done; and Mr °f Mudge has feveral times recovered the circular figure gatrurnent; when he had inadvertently gone too far with the para. - L bolic, and ultimately finiihed the metal on the poliflier T; ao7 without the ufe of the hones. t j. try the it w;n now be proper to try the figure of the fpe- the me- cu^um» an optical or mathematical inftrument-maker upon other occafions. Having cleaned the parts to be foldered very well, cut out a piece of tin-foil the exadt fize of them ; then dip a feather into a pretty ftrong folu- tion offal ammoniac in water, and rub it over the fur- faces to be foldered ; after which place the tin-foil be¬ tween them as faff as you can (for the air will quickly corrode their furfaces fo as to prevent the folder ta¬ king), and give the whole a gradual and fufficient heat to melt the tin. If the joints to be foldered have been made very flat, they will not be thicker than a hair: though the furfaces be ever fo extenfive, the foldering may be conduced in the fame manner ; only care mull be taken, by general prefiure, to keep them clofe together. In this manner, for inftance, a filver graduated plate may be foldered on to the brafs limb of a quadrant, fo as not to be difcernible by any thing but the different colour of the metals. This method was communicated to our author by the late Mr Jack- fon, who during his life kept it a fecret, as he ufed it in the cooftruftion of his quadrants. In Plate CCXXVIII. are figured the fhape of the leaden tool for rough-grinding ; the hones ; and the apparatus to be applied in the mouth of the telefcope, to afcertain the true figure of the fpeculum.

Having caft the fpecula, and poliflied them accord¬ ing to the diredtions already given, you muft next pro¬ vide a tube of plate brafs, well fmoothed, for the body of your telefcope; and whofe length muft be deter¬ mined by the focal length of the large fpeculum. This tube muft be painted black on the iniide, in order to reflcdt as little extraneous light as poflible. When the telefcopes are fmall, brafs is the ufual material of the tube; but when large, the expence will be leflened by making them of wood. This tube muft have a flit in one of its fides, for allowing the fmall mirror to Aide up and down.

In this eye¬ piece are placed the two lenfes which magnify the image from the mirrors, and which are kept in their proper places by the rings S, T, V, X.

The former of thefe is placed juft behind the large mirror; the latter in the place where the neareft eye-glafs fhould ftand. If the light palling through the fmall hole in the large circle falls exadly on the interfedion of the hairs, it (hews that the large fpecu¬ lum is properly placed ; if not, its fituation muft be altered till this is accomplifhed.

Fig. 12. Shews a telefcope of the Newtonian form, in which the plane fpeculum is fomewhat nearer the large one than in thofe formerly defcribed: in confe- quence of which this requires a fmall eye-piece at the ait fide, that the magnifying glafs may be placed at a fuf- Of adjuft- ficient diftance from it. This telefcope is to be ad- mfrrors of ju^ec^ 'n ^ following niann^r- Let there be provided a Newtoni-^O circles °f pafteboard, reprefented fig. 13. and 14. an tele- both of which are perforated in fuch a manner, that fcope. the tube of the telefcope may juft enter the perfora¬ tion. The circle fig. 13. is divided into quadrants, at each of which is pricked a hole with a pin. That re¬ prefented fig. 14. is alfo divided into quadrants; but, inftead of pin-holes, has black lines drawn upon it. The former is to be fixed on the open end of the tube, and the latter on the end where the concave fpeculum is placed. The telefcope is then to be turned towards the fun, fo that the little fpecks of light palling thro’ the pin-holes of the circle fig. 13. fall upon the black circular lines of fig. 14. Have then ready another piece of pafteboard, fig. 15. perforated with pin-holes in five different places as there reprefented. This piece muft exa&ly fit the opening of the telefcope; and while the tube continues thus turned ftraight to the fun, look through the eye-piece. If all the fpecks of light co¬ ming through the holes in the pafteboard are feen di* ftimft in the plane mirror, it is a fign that the mirrors are in a proper pofition with regard to each other: but if not, fome of them will not be feen at all, or will appear confufed and indiftinft; in which cafe^ the fitu- atioUiOf. the mirrors muft be altered till the light ap- I C S. Part III. pears bright and d!ftin&. Mechanifm In the application of telefcopes to aflronomical in- Q • ftruments and many other purpofes, it is abfolutelyjH^^yj neceffary to fix the plane of the crofs-hairs exa&ly- -j upon the plane of the pidture of an objeft ; which may of fl*fng eafily be done from a knowledge of the following pro-crofs-hairs \ perties. Firft, let the interval between the two con-in the foci j vex glaffes of the telefcope be adjufted to ftiew an °b-°fo ; jeft diftin&ly ; and if the hairs appear confufed, they copes’ . ' will feem to dance upon the objeft, while the eye moves fideways; and in dancing, if they feem to move the fame way as the eye does, they lie behind the pi&ure of the objedt; but if they move the con¬ trary way, they lie before it ; and muft be removed accordingly, till they appear diftindl; and then they will alfo feem fixed upon the objedt, notwithftanding the motion of the eye. Secondly, let the interval be¬ tween the hairs and the eye-glafs be firft adjufted, till the hairs appear diftindt : then, if the objedt appears confufed, it will alfo appear to dance while the eye moves fideways ; and in dancing, if it moves the fame way as the eye does, its pidture is behind the hairs; if the contrary way, its pidture is before them ; and to bring it to the hairs, either the objedt-glafs muft be moved, or elfe the hairs and eye-glafs both together. In both thefe cafes, it is the confufed objedt (for the hairs may alfo be called fo) that feems to move, and the diftindtoneto ftand ftill; as in vifion with thema- ked eye. For, to a perfon in motion, fuppofe hp be walking, any objedt appears fixed that he fixes his eyes upon and fees diftindtly, while the reft that are nearer or farther off appear confufed and in motion ; the reafon of it is too obvious to need an explanation. But to (hew it in the telefcope, let A be the interfec- plate tion of the crofs-hairs, and hik pencil of rays flow-CCXXV. j ing from it, which, after refradtion through the eye-^S- *•t0 4! glafs e a i, belong to the focus k, either at a finite or an infinite diftance. Draw A e, the axis of this pen¬ cil, cutting theobjedl in and its pi&ure in q; and let the emergent rays of the pencil q a A, flowing from q, cut the emergent rays of the former pencil in the' points />, and belong to the focus b, either at a finite or an infinite diftance. Now, if the eye be placed at any point 0 in the common axis of thefe pencils, the points A, will both appear in the fame diredlion 0 e ; but if the eye be moved fideways from 0 to p, the point Q_jwill appear in the diredlion pa, 'and the point A in the diredlion p i. And from hence the rea¬ fon of the foregoing cafes will be fufficiently manifeft, by attending to the figures. Laftly, while the focufes A q are disjoined, the mutual inclination of the emer¬ gent rays in one pencil, muft be different from the mutual inclination of the emergent rays in the other ; and fo the humours of the eye cannot be adapted to colledt the rays in both pencils to two diftindl points. If one be diftindl, the other will be confufed, and iu a different part of the retina; (except when the eye is in the axis: ) but when the focufes A, q, are united* the focufes k, b, of the emergent rays will alfo be united ; and confequently the coinciding rays of both < pencils will be united in the fame point of the re¬ tina, wherever the pupil of the eye be placed; and therefore the correfponding points of the objedt and crofs-hairs will appear fixed together without any j parallax. When. PartHI. OPT Wechanifm When the place of the hairs is thus determined, it I °f . may be of ufe to meafure their diltance from the ob- InftrumentJe("*'S^s» wh*ch >s exafteft way of finding its fo- cal dittance, if the object be very remote. And to keep this diftance always the fame whenever the telefcope is ufed, it is convenient to have marks or itops at the end of each joint of the tube. For then, whatever eye- glafs be applied, the objeft and hairs will both ap¬ pear diftinA at the fame time, and without parallax. Inftead of hairs, the fineft filver wires are now made 1I4 ufe of, but are ftill called Awv. Line of A line drawn from the interfe&ion of the hairs collimation through the centre of refra&ions in the objetf-glafs, de ned. whether it coincides with the axis of the glafs or is inclined to it, is called the ef collimation or line of fight; becaufe this line produced, falls upon the objedl in that point whofe image falls upon the inter- fedlion of the hairs: and therefore the flraight ray that deferibes this line, anfwers to the vifual ray by which we take aim at an objeft with plain-fights. Hence, when the objeft-glafs and hairs are firmly fix¬ ed in a ftrong tube, or to a ftraight ruler, it is mani- feft, that the line of fight is as immutable with re- fpeft to the tube, as if two little holes or plain- fights were fubftituted in the places of the interfec- tion of the hairs, and of the centre of refradtions in liJ the objedt-glafs. JJow to ad- order to fet the line of fight parallel to a given Kurt tele- line upon the plane of an inftrument, the objeft-glafs Ifcopic mu ft be firmly fixed, and the ring or plate that carries |r£ ts’ the crofs-hairs muft have two gradual motions in its own plane by two ferews at right angles to each other; for by this means the interfedlion of the hairs may be moved to any given point in that plane. Thefe motions are effedled by three brafs plates laid over one another. The uppermoft, having a circular hole in it, over which the hairs are ftrained, Aides over the middlemoft in the dire&ion of an oblong hole cut in it, whofe breadth is fomewhat greater than that of the hole above it; and thefe two together Aide fideways over the undermoft plate, in which there is a larger Plate oval hole. We Aiall deferibe thefe plates more parti- 'pCXXVIII.cularly in a contrary order. On each fide of the oval | 4- h0le in the middle of the plate R laft mentioned, two brafs ledges m, n, are firmly riveted to receive the dove-tailed fides of the plate S ; and the contiguous ends of both thefe plates are turned up fquare at b and e; and through a hole b, in the middle of the part turned up in the larger plate R, there works a pretty thick ferew a be, whofe fore-end c being filed to a neck, goes through a hole e in the lip of the other plate S ; and in the end of the neck c there is made a fmall ferew hole to receive a ferew-pin d; fo that by turning the ferew abc with a kind of a watch-key, the plate S is moved backwards or forwards between the ledges m, n. The figure T reprefents two more ledges o, p, that are to be riveted upon the plate S; thefe ledges are part of the plate T turned up at right angles to them, in which part there is the like contri¬ vance of a ferew abed to move a third plate V be¬ tween the ledges o, p, at right angles to the former motion. The filver wires are ftrained over the hole in the plate V by four fmall peggs, that fix them in four little holes. The other end of the plate R, oppofite to the part b that carries the ferew, is bent fquare the ICS. 5633 contrary way to the part b\ or, which anfwers the fameMechaaiim purpofe, one ledge ef of the plate X bent fquare, is °.f . riveted to the backfide of the plate R at the end op- inftmrnents polite to the ferew b ; and its other ledge^ is ferew- ed to the fide of the tube of the telefcope ; and the necks of the ferews go through long Aits in this ledge, to give liberty of placing it accurately at the due di¬ ftance from the objeft-glafs : and for the purpofe of letting this brafs work into the tube, two large Aits muft: be cut in two contiguous fides of it: one of which may heft be covered with a thin piece of horn, to ad¬ mit the light of a candle upon the hairs in obferving fmall liars in the night time. To make the line of fight through a moveable te¬ lefcope parallel to a given line YZ upon a fixed plane; Fig. 5-, let the ends of the tube of the telefcope, whether fquare or cylindrical, be put through two holes in two fquare plates abedt and efgh, made exaftly equal to each other, and fo fixed to the tube that the fides of the one may be exaftly parallel to the fides of the other ; which is eafily done by applying their corners a,e, to the given line YZ, and by drawing two lines a i, e k> perpendicular to it, upon the given plane, and by making all the correfponding fides, a b,ef, coin¬ cide with thefe perpendiculars. Then obferve what point of a remote objeft is covered by the interfec- tion of the hairs when the corners a, e, touch the given line YZ, and likewife what other point is covered by them when the oppofite corners c, g, touch the fame line in the fame places, that is, when the telefcope is turned upfide down or half round. Then conceiving thefe two points of the objefl to be connedled by a ftraight line, move the crofs-hairs by the two ferews, till you judge their interfedtion bifedts that line ; and by repeating the fame pradtice, you may foon bring the interfedlion of the hairs to cover one and the fame point of the objedt, when the oppofite cor¬ ners of the fquares are fuccefiively applied to the line YZ ; and then the line of fight will be parallel to it. To ftiew the reafon of this pradtice, we may fup- pjg pofe the centre of refradtion in the objedl-glafs to be 0 any point /of the fquare abed, and the interfedlion of the hairs to be any point m of the fquare efgh. Upon the plane of the firft fquare, and through its centres, draw lo*, and take o* equal to 0/; alfo upon the plane of the fecond fquare, and through its centre p, draw mp y., and take p y equal to pm. Join /wand x/q and fuppofing /«and xvparallel to the axis 0 p, join m n, n», v y. Then becaufe the r.efpedlive fides about the equal angles mp n, yp v, are made equal, the lines m n, y*, oppofite to them, are alfo equal and parallel. Now the parallel lines «/, p 0, *x, produced will fall upon a remote objedl in three points fo clofe together as to appear like a fingle point thro’ the te¬ lefcope ; and confequently the planes of the parallel triangles Imn, X/tcv, produced, will cut the fame ob¬ jedl in two parallel lines fo clofe together as to appear but one line through the telefcope; and fince the angles id ln, /«xv, are equal, the interfedtion of the hairs, now at wand then turned half round to y, will cover two points in that line equidiftant from the point abovementioned, and on oppofite fides of it: therefore, by removing the ir.terftdlion from m to n, it will appear to bifedt the interval between thofe two points; and then the line of fight«/ will be parallel 5634 ° p T Mechanifin to the axis p 0, and to the Tides of the parallelepiped, and alfo to the given line YZ. Optical ^ telefcope thus prepared, may be ufeful upon fe- veral occafions ; as if it be required to rectify the hairs in a telefcdpe fixed to any inftrument, fo as to fet the line of fight parallel to a given line upon the plane of the inftrument. Apply the corners of the fquares of the telefcope abovementioned to the given line, and obferving what point of a remote objeft is covered by its crofs hairs, move the crofs hairs of the fixed tele¬ fcope till they cover the fame point of the objeft, and 215 the bufinefs is done. Of reflify- But tj,e telefcopic fights of quadrants and feftants, ff*Ls of whofe planes may be readily placed in any given po- quadrants fture, may be reftified by a plumb-line.

If it be done before, Plate then we fuppofe the telefcope TL fixed to the qua- CCXXIX. drant, which we fuppofe continued a little farther than fig. 18.19. t}ie fourth part of a circle. Choofing then an objedt pretty near the horizon ; let us look thro’ the tele- fcope, in the ufual pollute of obfervation, and ob- ferve the point in the objedl marked by the crofs- bairs ; and at the fame time we are to note moft nice¬ ly the point £•, which the plumb-line fcg, hung from the centre f of the quadrant, cuts on the limb. Then we are to invert the quadrant into the pofture of fig. 19. (which is eafily done by the ufual contrivances forma- naging great quadrants, by toothed femicircles and endlefs ferews) keeping ftill the telefcope TL nearly tipon the fame height from the ground as before, un- lefs the objedl we look at be fo far diftant, that the breadth of the quadrant fubtends but an infenfible angle. But yet for certainty, it is better to keep the telefcope, as it is faid, upon the fame height from the floor ; then diredl the telefcope TL, that the crofs hairs may cover exadlly the fame point in the objedl, as before in the pofture of fig. 18. And hang¬ ing now the plumb-line afg on the limb of the qua¬ drant, let us remove it to and fro, till we find out the exadl point a, from which the plumb-line being hung, (hall moft nicely hang over the centre of the quadrant f Then carefully marking the point a, let us divide the arch c a into two equal parts in b ; and drawing b f the point b is the point from which we are to be¬ gin the divifions of the quadrant: and the line of col- limation through the telefcopic fight, (lands exadlly at right angles to the line bf. So that the quadrant bfd being compleated and divided, the faid line of light thro’ the telefcope runs exquifitely parallel to the line fd. “ In the next place, fuppofing the quadrant truly compleated and divided; and that we defigned to fix thereto the telefcopic fight TL, fo that the line of fight may run exadlly at right angles to the line bf or parallel to the line df ; we are to do as in the foregoing praxis. And if, in dividing the arch ac, we find its half exadlly coincident with the points, we have our defire. But if it differs from the point bt and falls between b and d> then the line of collimation through the telefcope ftands at an obtufe angle with I C S. Partin. the line bf; and the inftritment errs in excefs : if this Meclianifm half arch fall without b and d, then the line of colli- „ °f . ; mation makes an acute angle with the line bf‘, andinftnimenti the inftrument errs in defedl. And by often trials, we ' - are to remove the crofs-hairs within the tube, fo much as is requifite to corredl this error. And when we have thus redlified them to their due place, there they are to be ftrongly fixed. Or elfe, in obfervations ta¬ ken by this inftrument, we are to make allowance for this error; by fubtradling from (if it be in excefs), or by adding to (if it be in defedl), each obfervation, fo much as we find the error to be. “ The reafon of this redlification is moft plain; for it is manifeft, that cfd wants of a full quadrant, as much as afd exceeds a quadrant. So the difference of the two arches in the two poftures being ac ; half this difference be added in fig. 18. or a b fubtradled in fig. 19. makes b d z complete quadrant. “ If we find our Inftrument errs in taking angles, and we defire to know the error more nicely than perhaps the divifions of the inftrument itfelf will (hew it, we are to do thus. Suppofing the quadrant bfd already accurately divided, and that the plumb-line plays over the point c\ and upon the inverfion of the inftrument, we find that before we can get it to play exadlly over the centre f we muft hang it over the point r, fo that the arch eb exceeds bc by the arch er; it is plain that the angle efa is the error of the inftrument: for had the plumb-line hung over a, and over the centre f in this latter pofture, the inftrument had been exadl; becaufe a is as much on one fide b, as c is on the other fide b. Wherefore efa being the angle by which our inftrument errs in obfervation, let us turn the inftrument into the ufual pofture of obfervation, as infig. 18. and hanging the plumb-line on the centre fy let us bring it to play nicely on the point e, and obferve what diftant objedl is covered by the crofs- hairs : then let us bring it to play exadlly on the point a, and obferve likewife what diftant objedl is pointed at by the telefcope-hairs. Laftly, by a large telefcope and micrometer, let us meafure the angle between tbefe two objedls, and we (hall have the angle of error much more nicely than it is poflible the angle efa (hould be given by the divifions on the limb of the quadrant e a. And thus much for adjufting a quadrant. “ A fextant is redlified in like manner ; if we confi- pjg der, that if from the centre f to the beginning of the divifions there be drawn the radius f d, and it be di¬ vided equally in c, and from c there be fufpended the plumb-line cb'. when the plumb-line hangs over the 60th degree at b, then the line f d lies horizontal; and confequently, if the line of collimation thro’ the tube be parallel tothis line alfo lies horizontal. To try which, whilft the fextant ftands in this pofture, obferve the 'objedl marked by the crofs-hairs; then invert the fex¬ tant, and over the point b hang the plumb-line; and when from the point b the plumb-line hangs over the middle point ct then again is the line/VJiorizontal in this pofture. Mark, then, whether the crofs-hairs co¬ ver the fame objedl as before: if they do, then the line of collimation is parallel to f d; if they do not, but the point in the objedl marked in this latter pofture be higher than the point marked in the firft pofture, the iuftrument errs in excefs ; if it be lower, the in¬ ftrument *rt III. OPT ichaniftn ftrument errs in defeft. And either we are to remove | the crofs-hairs, till we bring all to rights, and there fruments t^iem 5 or ^ t^ie meth°ds before laid down in the re&ification of the quadrant, we are to find the quan¬ tity of this erroneous angle, and to allow for it in ob- fervation. “ In inftrumentsfurnilhed with two pair of telefco- pic fights, one on a fixed arm, and the other on a move- able arm (by the ancients termed an alidade); it is eafy reftifying the fights on the moveable arm, thus. [ After the fights on the fixed arm are redified by what foregoes, bring the index of the moveable arm, to the t beginning of the divifions on the limb of the inftru- ment, be it quadrant or fextant, &c. it is then mani- feft, that the line of collimation through the moveable telefcope (if it be right) fhould lie parallel to the line of collimation through the fixed telefcope. Obferve, therefore, whether the crofs-hairs in both telefcopes do at the fame time cut the fame ftar, or fall on the fame point in an objeft diftant three or four miles. If they do, then the moveable telefcope agreeing with the fixed, and the fixed being fuppofed re&ified to the idivifions on the inftrument, the moveable is right like- wife. But if the hairs in the moveable telefcope do not agree in marking the fame point with the crofs-hairs in the fixed telefcope, then the hairs in this moveable tele¬ fcope are to be removed (by whatever contrivance there is for that purpofe) and brought to rights, and there fixed.” There are other methods propounded for reftifying telefcopic fights on other forts of inftruments, by means of obfervations towards the zenith, as our for¬ mer methods have been employed towards the horizon. But it is fufficient here to lay down only what fore¬ goes, as being of the greateft and mod frequent ufe : referring for the others to M. Picard’s “ Treatife of the meafure of a degree of a great circle of the earth,” publilhed at the end of the “ Memoirs of a Natural Hiltory of animals, &c.” by the Royal Academy at Paris; tranfiated into Englifh and printed at Lon¬ don 1688, folio. Sect. VII. Of the different Merits of Microfcopes and Telefcopes^ compared -with one another; how far we may reafonably depend on the Difcoveries made by themt and what hopes we may entertain of further Improvements. j Advantages t^HE advantages arifing from the ufe of microfcopes tfrom the and telefcopes depend in the firft place upon their pro- jfefe of mi- perty of magnifying the minute parts of obje&s, fo wrofccpes t]13t they can by that means be more diftinelly viewed Ifcopcs e" bY lbe eye ; and, fecondly, upon their throwing more || ' light into the pupil of the eye than what is done without them. The advantages arifing from the magnifying power would be extremely limited, if they were not alfo accompanied by the latter : for if the fame quan¬ tity of light is fpread over a large portion of furface, it becomes proportionably diminifhed in force; and therefore the objects, though magnified, appear pro¬ portionably dim. Thus, though any magnifying glafs firould enlarge the diameter of the cbjtft to times, and confequer.tly magnify the furface too times, yet if the focal diftai ce of the glafs was about eight inches, (pro¬ vided this was pofiible), and its diameter only about the fize of the pupil of the eye, the objeft would appear 100 I G S. 5635 times more dim when we looked thro’ the glafs, than Mechanifnj when we beheld it with our naked eyes; and this, even °f on a fuppofition that the glafs tranfmitted all the light, which fell upon it, which no glafs can do. But if the - - focal diftance of the glafs was only four inches, tho* its diameter remained as before, the inconvenience would be vaftly diminilhed, becaufe the glafs could then be placed twice as near the objeft as before, and confequently would receive four times as many rays as in the former cafe, and therefore we would fee it much brighter than before. Going on thus, ftill di- minifhing the focal diltance of the glafs, and keeping its diameter as large as pofiible, we will perceive the objeft more and more magnified, and at the fame time very diftindl and bright. It is evident, however, that with regard to optical inftruments of the microfcopic kind, we mull fooner or later arrive at a limit which 117 cannot be pafled. This limit is formed by the follow- Limits of ing particulars. 1. The quantity of light loft in pafs- 'bef®dya""e ing through the glafs. 2. The diminution of the glafs itfelf, by which it receives only a fmall quantity of crofcopcs, rays. 3. The extreme fhortnefs of the focal di¬ ftance of great magnifiers, whereby the free accefs of the light to the objeft which we wi(h to view is impe¬ ded, and confequently the refle&ion of the light from it is weakened. 4. The aberrations of the rays, oc- cafioned by their different refrangibility. To underftand this more fully, as well as to fee how far thefe obftacles can be removed, let us fuppofe the lens made of fuch a dull kind of glafs that it tranfmits only one half of the light which falls upon it. It is evident that fuch a glafs, of four inches focal diftance, and which magnifies the diameter of an objeft twice, ftill fuppofing its own breadth equal to that of the pupil of the eye, will (hew it four times magnified in furface, but only half as bright as if it was feen by the naked eye at the ufual diftance; for the light which falls upon the eye from the objeft at eight inches diftance, and likewife the furface of the objeft in its natural fize, being both reprefented by 1, the furface of the magnified objedf will be 4, and the light which makes that magnified object vifible only 2 ; becaufe though the glafs receives four times as much light as the naked eye does at the ufual diftance of diftindt vifion, yet one half is loft in pafiing through the glafs. The inconvenience in this refpedt can therefore be re¬ moved only as far as it is pofiible to increafe the clear- nefs qf the glafs, fo that it (hall tranfmit nearly all the rays which fall upon it ; and how far this can be done, hath not yet been afeertained. The fecond obftacle to the perfedlion of microfcopic glaffes is the fmall fize of great magnifiers, by which, notwithftanding their near approach to the objedl, they receive a fmaller quantity of rays than might be, ex- pedled. Thus, fuppofe a glafs of only tV1 of an inch focal diftance ; fuch a glafs would increafe the vifible diameter 80 times, and the furface 6400 times. If the breadth of the glafs could at the fame time be preferved as great as that of the pupil of the eye, which we (hall fuppofe Ath of an inch, the objedk would appear magnified 6400 times, at the fame time that every part of it would be as bright as it appears to the naked eye. But if we fuppofe that this magnifying glafs is only -jV11 of an inch in dia¬ meter, it will then only receive f111 of the light which other- 5636 OPT Mechanifm otherwife would have fallen upon it; and therefore, in- °( Head of communicating to the magnified objedt a Inftrunients . col. 2.

This is found in the warm parts of Europe as well as in America, and grows wild on the fides of the roads in Sicily, Naples, and Spain; but it is probable that the feeds of it may have been brought thither from America. This has oval or roundifh branches, com- prefied on their two fides flat, and have fmall leaves coming out in knots on their furface, as alfo on their upper edges, which fall off in a fhort time; and at the fame knots are three or four fharp fpines, which do not appear unlefs they are clofely viewed ; but, on being handled, they enter the flefh, feparate from the plant, and fo are very troublefome and difficult to get out. The branches fpread near the ground, and frequently trail upon it, putting out new roots; fo are extended to a confiderable didance, and never rife in height: thefe are flefhy and herbaceous while young; but, as they grow old, become drier, of a tough contexture, and have ligneous fibres. The flowers come out on the upper edges of the branches, though fometimes they are produced on their fides : thefe fit upon the embryo of the fruit, and are compofed of feveral round¬ ifh concave petals, which fpread open. They are of pale yellow colour, and appear in July and Augufl. They are fucceeded by an oblong fruit, whofe fkin or cover is fet with fmall fpines in cluders; and the infide is flefhy, of a purple or red colour, in which are lodged many black feeds. 1. The cochinilifera, or cochineal fig; fo called from its being the food of the cochineal infed. It hath oblong, fmooth, green branches, which grow ere& to the height of 8 or to feet, with but very few fpines, and thefe fo foft that they are not trouble¬ fome when handled. The flowers of this are of a purple colour; and fit on the embryo of the fruit, like thofe of the former fort, but do not expand like them. This kind grows naturally in Jamaica; where it is pro¬ bable that the true cochineal might be difcovered if perfons of fkill were to fearch for it. The vulga¬ ris is the only kind which can be raifed in this coun¬ try without great difficulty; and may be propagated by flips, in a light mould.

It is' alfo ufed for the god who was thought to give the an¬ fwer, and the place where it was given. The credit of oracles was fo great, that in all doubts and difputes their determinations were held facred and inviolable : whence vad numbers flocked to them for advice about the management of their affairs ; and no ' bufinefs of any confequence was undertaken, fcarce any peace concluded, any war waged, or any new form of government indituted, without the advice and approbation of fome oracle. The anfwers were ufually given by the intervention of the pried or priedefs of the god who was confulted; and generally expreffed in fuch dark and unintelligible phrafes, as might be eafily wreded to prove the truth of the oracle, what¬ ever was the event. It is not, therefore, to be won¬ dered at, that the prieds who delivered them were in the highed credit and edeem, and that they improved this reputation greatly to their advantage. They ac¬ cordingly allowed no man to confult the gods, before he had offered codly facrifices, and made rich prefents to them. And to keep up the veneration for their oracles, and to prevent their being taken unprepared, they admitted perfons to confult the gods only at cer¬ tain dated times; and fometimes they were fo cau¬ tious, that the greated perfonages could obtain no an¬ fwer at all. Thus Alexander himfelf was perempto¬ rily denied by the pythia, or priedefs of Apollo, till fhe was by downright force obliged to afcend the tri¬ pos; when, being unable to refitt any longer, (he cried out, Thou art invincible: and thefe words were accep¬ ted indead of a farther oracle. Of the ambiguity of oracles, the following, out of a great many examples, may be mentioned. Croefus having received from the pythonefs this anfwer, That by paffing the river Halys, he would dedroy a great empire; he underdopd it to be the empire of his ene¬ my, whereas he dedroyed his own.—The oracle con¬ fulted by Pyrrhus gave him an anfwer, which might be equally underdood of the viftory of Pyrrhus, and the vidtory of the Romans his enemies: Aio te, JEacida, Romanos vincere pojfe. The equivocation lies in the condru&ion of the La¬ tin tongue, which cannot be rendered in Englifli.— The pythonefs advifed Crcefus to guard againd the mule. The king of Lydia underdood nothing of the oracle, which denoted Cyrus defcended from two dif- fereht nations; from the Medes, by Mandana his mo¬ ther, the daughter of Adyages; and from the Perfians, by his father Cambyfes, whofe race was by far lefs grand and illuftrious.—Nero had for anfwer, from the oracle of Delphos, that feventy-three might prove fa¬ tal to him. He believed he was fafe from all danger till that age; but, finding himfelf deferted by every one, and hearing Galba proclaimed emperor, who was 73 years of age, he was fenfible of the deceit of the oracle. When men began to be better indru&ed by the lights philofophy had introduced into the world, the falfe oracles infenfibly lod their credit. Chryfippus filled an entire volume with falfe or doubtful oracles. Oenomaus, to be revenged of fome oracle that had. deceived him, made a compilation of oracles, to flievv thiir ridicule and vanity. Eufebius has preferred. fome Oracle. Oracle. ORA [ 5541 ] ORA fome fragments of this criticifra on oracles by Oeno- ' maus. “ I might (fays Orig.en) have recourfe to the authority of Ariftotle and the Peripatetics, to make the Pythonefs much fufpefied; I might extradf from the writings of Epicurus and his fedtators an abun¬ dance of things to difcredit oracles; and I might fhew that the Greeks themfelves made no great account of them.” The reputation of oracles was greatly leffened when they became an artifice of politics. Themiftocles, with a defign of engaging the Athenians to quit Athens, and to embark, in order to be in a better condition to refill Xerxes, made the Pythonefs deliver an oracle, commanding them to take refuge in wooden walls. Demofthenes faid, that the Pythonefs Pbilip- pifed; to fignify that Ihe was gained over by Philip’s prefents. The ceffation of oracles is attefted by feveral pro- phane authors; as Strabo, Juvenal, Lucan, and others. Plutarch accounts for the caufe of it, either that the benefits of the Gods are not eternal as themfelves are; or that the genii, who prefided over oracles, are fub- jedl to death; or that the exhalations of the earth had been exhaufted. It appears that the laft reafon had been alleged in the time of Cicero, who ridicules it in his fecond book of Divination, as if the fpirit of pro¬ phecy, fuppofed to be excited by fubterraneous effluvia, had evaporated by length of time, as wine or pickle by being long kept. Suidas, Nicephorus, and Cedrenus, relate, that Au- guftus, having confulted the oracle of Delphos, could obtain no other anfwer but this: “ The Hebrew child whom all the Gods obey, drives me hence, and fends me back to hell: get out of this temple without fpeaking one word.” Suidas adds, that Auguftus dedicated an altar in the Capitol with this infeription, “ To the eldeft Son of God.” Notwithftanding thefe teftimonies, the anfvver of the oracle of Delphos to Auguftus feems very fufpicious. Cedrenus cites Eu- febius for this oracle, which is not now found in his works; and Auguftus’s peregrination into Greece was 18 years before the birth of Chrift. Suidas and Cedrenus give an account alfo of an ancient oracle delivered to Thulis, a king of Egypt, which they fay is well authenticated. The king ha¬ ving confulted the oracle of Serapis, to know if there ever was, or would be, one fo great as himfelf, re¬ ceived this anfwer: “ Firft, God, next the Word, and the Spirit with them. They are equally eternal, and make but one, whofe power will never end. But thou, mortal, go hence, and think that the end of the life of man is uncertain.” Van Dale, in his treatife of oracles, does not be¬ lieve that they ceafed at the coming of Chrift. He relates feveral examples of oracles confulted till the death of Theodofius the Great. He quotes the laws of the emperors Theodofius, Gratian, and Valentinian, againft thofe who confulted oracles, as a certain proof that the Cuperftition of oracles ftill fubfifted in the time of thofe emperors. According to others, the opinion of thofe who be¬ lieve that the demons had no (hare in the oracles, and that the coming of the Meffiah made no change in them,-and the contrary opinion of thofe who pretend that the incarnation of the Word impofed a .general filence on all oracles, ftiould be equally reje&ed. They Onclr, allege, that two forts of oracles ought to be diftin- guifhed: the one dhftated by the fpirits of darknefs, who deceived men by their obfeure and doubtful an- fwers; the other, the pure artifice and cheat of the priefts of falfe divinities. As to the oracles given out by demons, the reign of Satan was deftroyed by the coming of the Saviour; truth (hut the mouth of lies; but Satan continued his old craft among idolaters. All the devils were not forced to filence at the fame time by the coming of the Meffiah ; it was on parti¬ cular occafions that the truth of Chriftianity, and the virtue of Chriftians, impofed filence on the devils. St Athanafius tells the Pagans, that they have been wit- ntffes themfelves that the fign of the crofs puts the devils to flight, filences oracles, and diffipates enchant¬ ments. This power of filencing oracles, and putting the devils to flight, is alfo attefted by Arnobius, Lac- tantius, Prudentius, Minutius Felix, and feveral others. Their teftimony is a certain proof that the coming of the Meffiah had not impofed a general filence on oracles. Plutarch relates, that the pilot Thamus heard a voice in the air, crying out, “ The great Pan is dead;” whereupon Eufebius obferves, that the ac¬ counts of the death of the demons were frequent in the reign of Tiberius, when Chrift drove out the wicked fpirits. The fame judgment, it is faid, may be pafled on oracles as on pojfetfions. It was on particular occa¬ fions, by the divine permiffion, that the Chriftians caffc out devils, or filenced oracles, in the prefence, and even by the confeffion, of the Pagans themfelves. And thus it is we fhould, it feems, underhand the paflages of St Jerom, Eufebius, Cyril, Theodoret, Prudentius, and other authors, who faid that the coming of Chrift: had impofed filence on the oracles. As to the fecond fort of oracles, which were pure artifices and cheats of the priefts of falfe divinities, and which probably exceeded the number of thofe that immediately proceeded from demons, they did not ceafe till idolatry was abolifhed, though they had loft their credit for a confiderable time before the coming of Chrift. It was concerning this more com¬ mon and general fort of oracles that Minutius Felix faid, they began to difeontinue their refponfes, ac¬ cording as men began to be more polite. But, how¬ ever decried oracles were, impoftors always found dupes, the grofleft cheats having never failed. Daniel difeovered the impofture of the priefts of Bel, who had a private way of getting into the temple to take away the offered meais, and who made the king believe that the idol confumed them.—Mundus, being in love with Paulina, the eldeft of the priefteffes of Ifis, went and told her, that the god Anubis, be¬ ing paffionately fond of her, commanded her to give him a meeting. She was afterwards ftiut up in a dark room, where her lover Mundus, whom ihe be¬ lieved to be the god Anubis, was concealed. This impofture having been difeovered, Tiberius ordered thole deteftable priefts and priefteffes to be crucified, and with them Idea, Mundus’s free-woman, who had conduced the whole intrigue. He alio commanded the temple of Ifis to be levelled with the ground, and her ffatue to be thrown into the Tiber; and, as to Mun- 31X2 dus, ORA Oracle 15 Oran. dus, he contented himfelf with fending him into bani/h- ment. . Theophilus, bifhop of Alexandria, not only de- ftroyed the temples of the falfe gods, but difcovered the cheats of the priefts, by fliewing that the ftatues, fome of which were of brafs, and others of wood, were hollow within, and led into dark paflages made in the wall. Lucian, in difcovering the impoftures of the falfe prophet Alexander, fays, that the oracles were chiefly afraid of the fubtilties of the Epicureans and Chrifti- ans. The falfe prophet Alexander fometimes feigned himfelf feized with a divine fury, and by means of the herb fopewort, which he chewed, frothed at the mouth in fo extraordinary a manner, that the ignorant people attributed it to the ftrength of the god he was pof- feffed by. He had long before prepared a head of a dragon made of linen, which opened and (hut its mouth by means of a horfe-hair. He went by night to a place where the foundations of a temple were digging; and, having found water, either of a fpring, or rain that had fettled there, he hid in it a goofe- egg, in which he had inclofed a little ferpent that had been juft hatched. The next day, very early in the morning, he came quite naked into the ftreet, having only a fcarf about his middle, holding in his hand a fcythe, and tolling about his hair as the priefts of Cy- bele; then getting a-top of a high altar, he faid that the place was happy to be honoured by the birth of a god.—Afterwards, running down to the place where he had hid the goofe-egg', and going into the water, he began to ling the praifes of Apollo and iEfcula- pius, and to invite the latter to come and (hew himfelf to men. With thefe words, he dips a bowl into the water, and takes out a myfterious egg, which had a god inclofed in it; and when he had it in his hand, he began to fay that he held -/Efculapius. Whilft all were eager to have a fight of this fine myftery, he broke the egg, and the little ferpent darting out, twifted itfelf about his fingers. Thefe examples (hew clearly, that both Chriftians and Pagans were fo far agreed as to treat the greater number of iracles as purely human impoftures.—That, in fad, all of them were fo, will be concluded by thofe who give equal credit to demoniacal infpiration, and demoniacal pojfeffion.

ORA- [ 6543 ] ORATORY; The art of fpeaking well upon any fubjeft, in order to perfuade. INTRODUCTION. $ i. Of the Rife and Progref of Oratory. H E invention of oratory is by the Egyptians, and the fables of the poets, afcribed to Mercury. And it is well known, that the Greeks made their deities the authors likewife of other arts, and fuppofed that they prefided over them. Hence they gave Mercury the titles of Aoj/j®- and both which names come words that fignify “ to fpeak.” And Ariftides call? eloquence the gift of Mercury; and for the fame rea- fon anciently the tongue was confecrated to him. He was likewife faid to be the interpreter or meffenger of the gods; which office very well fuited him, as he ex¬ celled in eloquence. Hence we read in the Sacred Wri¬ tings, that when the people of Lyftra took Barnabas and Paul for gods in human fhape, becaufe of that fudden and furprifing cure which was wrought upon the lame man, they called-Barnabas y«/>/Arr, and Paul Mercury; for this reafon, as the infpired writer tells us, ‘ becaufe he was the chief fpeaker,’that is (as the fpeftators then thought) the interpreter or fpokefman of Barnabas. But to pafs over thefe fidh’ons of the heathen deities, let us hear what Quintilian fays of the origin of this art; who feems to give a very probable account of it in the following paffage. ‘ The faculty of fpeech (fays he) we derive from nature; but the art from obfervation. For as in phyfic, men, by feeing that fome things promote health and others deftroy it, form¬ ed the art upon thofe obfervations; in like manner, by perceiving that fome things in difcourfe are faid toad- vantage, and others not, they accordingly marked thofe things, in order to imitate the one, and avoid the other. They alfo added fome things from their own reafon and judgment, which being confirmed by ufe, they began to teach others what they knew themfelves.’ But no certain account can be given when, or by whom, this method of obfervation firft began to take place. And Ariftotle fuppofes, not without reafon, that the firft lineaments of the art were very rude and imperfed. Paufanias, indeed, in his Defcription of Greece, tells us, thatPittheus, the uncle of Thefeus, taught it at Trezene a city of Peloponne- fus, and wrote a book concerning it ; which he read himfelf, as it was publifhed by one of Epidaurus. But as Pittheus lived above 1000 years before Paufanias, who flourifhed in the time of the emperor Hadrian, fome are of opinion he might be impofed upon by the Epidaurian, who publifhed this book under the name of Pittheus. But be that as it will,itis veryreafonable to believe, that the Greeks had the principles of this art fo early as the time of Pittheus. For Thefeus his nephew lived not long before the taking of Troy, which, accor- dingto Sir liaacNewton,happened 904years before the birth of Chrift; at which time Cicero thought it was in muchefteem among them. ‘ Homer (lays he) would never have given Ulyffes and Neftor in the Trojan wars fo great commendations on account of their fpeechcs (to one of whom he attributes force, and to the other fweetnefs of expreffion) if eloquence had not in thofe times been in great repute.’ And left any one ffiould imagine, that in thofe days they made ufe only of fuch helps as nature and pra&ice could afford them ; the fame poet informs us, that Peleus fentPhenix with his fon Achilles to the Trojan war, to inftrud him not only in the art of war, but iikewife of eloquence. But whcr were the profeffors of this art for fome ages fol¬ lowing, is not known. For Quintilian fays, that af¬ terwards Empedocles is the firft upon record, who at ¬ tempted any thing concerning it. And he, by Sir Ifaac Newton’s account, flourifhed about 500 years af¬ ter Troy was taken. At which time, as Cicero ob- ferves, men being now fenfible of the powerful charms of oratory, and the influence it had upon the mind, there immediately arofe feveral mafters of it; the chief of whom are mentioned by Quintilian, who tells us, that ‘ the oldtft writers upon this art are Corax and Tifias, both of Sicily. After them came Gorgias of Leontium in the fame ifland, who is laid to have been the fcholar of Empedocles, and by reafon of his great age (for he lived to be 109 years old) had many co¬ temporaries. Thrafymachus of Chalcedon, Prodicus of Cea, Protagoras of Abdera, Hippias of Elis, and Al- cidamus of Elea, lived in his time; as likewife Anti¬ phon, who firft wrote orations, and alfo upon the art, and is faid to have fpoken admirably well in his own defence ; and befides tkefe, Polycrates, and Theodore of Byzantium.’ Thefe perfons contributed different ways towards the improvement of the art. Corax and Tifias gave rules for methodizing a difcourfe, and ad- jufting its particular parts;- as may be conje&ured from Cicero’s account of them, who fays, * Though fome had fpoke well before their time, yet none with order and method.’ But Gorgias feems to have ex¬ celled all the reft in fame and reputation: for he was fo highly applauded by all Greece, that a golden ftatue was ereded to him at Dtlphos, which was a di- ftinguifhing honour conferred upon him only. And he is faid to have been fo great a mafter of oratory, that in a public affembly be would undertake to declaim immediately upon any fubjeiSl propofed to him. He wrote, as Cicero informs us, in the demonftrative or laudatory way ; which requires molt of the fublime, and makes what Diodorus Siculus fays of him the more probable, that ‘ he firft introduced the ftrongeft figures, members of periods oppofite in fenfe, of an equal length, or ending with a like found, and other ornaments of that nature.’ And hence thofe figures, which give the greateft force and luftre to a difcourfe, were anciently called by his name. Cicero tells us further, that Thrafymaehus and Gorgias were the firft who introduced numbers into profe, which Ifocrates afterwards brought to perfeftion. Quintilian likewife mentions Protagoras, Gorgias, Prodicus, and Thra¬ fymachus, as the firft who treated of common-places, and fiiewed the ufe of them for the invention of argu¬ ments. Nor mult we omit Plato, whole elegant dia¬ logue upon thje fubjed is ftill extant, which he entitles Gorgias 5544 O R A T Gorgias. For though he does not lay down the com¬ mon rules of the art-; yet he very well explains the nature of it, and maintains its true end and ufeagainft the generality of its profeffors, who had greatly per¬ verted the original defign of it. Thus by the ftudy and induftryof fo many ingenious and great men, the art of oratory was then carried to a confiderable height among the Grecians. Though many of thofe, who profeffed it in thofe times, employed their flcill rather to promote their own reputation and applaufe, than to ferve the realinterefts of truth and virtue,.. ‘ For they propofed in an arrogant manner (as Cicero fays) to teach how a bad caufe might be fo managed, as to get the better of a good one.’ That is, they would undertake to charm the ears and (trike the paffions of their hearers in fo powerful a manner, by fophidical reafonings, turns of wit, and fine language, as to impofe falfebood upon them for truth ; than which nothing could be either more difingenuous in itfelf, or prejudicial to fociety. But thofe who fucceeded them, feem to have con- fulted better, both for their own honour, and that of their profeffion. Ifocrates was the moft renowned of all Gorgias’s fcholars, whom Cicero frequently ex¬ tols with the higheft commendations, as the greateft mailer and teacher of oratory ; ‘ whofe fchool (as he fays) like the Trojan horfe, fent forth abundance of great men.’ Arittotle was chiefly induced to engage in this province from an emulation of his glory ; and would often fay in a verfe of Sophocles, fomewhat va¬ ried to his purpofe, To be filent it is a (hame; While liberates gets Inch fame. Quintilian fays they both wrote upon the art, though there is no fyftem of the former now extant. But that of Ariftotle is efteemed the bed and mod complete of any in the Greek language. In this age the Gre¬ cian eloquence appeared in its highed pcrfe&ion. De- modhenes was an hearer both of Ifocrates and Plato, as al o of Ifseus (ten of whofe orations are yet extant); and by the affidance of a furprifing genius, joined with indefatigable indudry, made that advantage of their precepts, that he has been always edeemed by the bed judges the prince of Grecian orators. His great adverfary and rival iEfchines, after his baniih- ment is faid to have gone to Rhodes, and employed his time there in teaching of rhetoric. Theode&es and Theophradus, both of them fcholars of Aridotle, imi¬ tated their mafier in writing upon the art. And from that time the philofophers, efpecially the doics and peripatetics, applied themfelves to lay down the rules of oratory ; which Socrates had before fepafated from the province of a philofopher. And there is yet pre- ferved a treatife upon this fubjeCl, which fome have aferibed to Demetrius Phalereus the peripatetic, and fcholar of Theophradus, though others more probably to Dionyfius of Halicarnaffus. Quintilian mentions fe- veral other farrvms rhetoricians in the following ages, who were likevvife writers ; as Hermagoras, Athe- T.ssus, ApolloniurMolon, Areus Caecilius, Dionyfius of Halicarnadus, Apollonius of Pergamus, and Theo¬ dore of Gadara. But of thefe nothing now remains upon the fubje& of oratory, except fome tradls pf Dionyfius, who flourilhed in the reign of Augudus Casfar. Nor have there been wanting fome eminent O R Y. writers of this kind among the Greeks fince the time of Quintilian ; two of whom we cannot omit to mention, Hermogenes, and Longinus the author of the incom- t parable treatife Of the Sublime,* book which can fcarce i be too much commended or too often read. It was long before Rome received this art, and not ; without difficulty at fird. The reafon was, becaufe the Romans were for feveral ages wholly addidted to ; military affairs, and to enlarge their territories; fo that they not only negledted to cultivate learning, but thought the purfuit of it a thing of ill tendency, by j diverting the minds of their youth from the cares and toils of war, to a more foft and indolent kind of life. Therefore fo late as the year of their city 592, when by the indudry of fome Grecians the liberal arts be¬ gan to flourifh in Italy, a decree palled the fenate, by which all philofophers and rhetoricians were ordered J to depart out of Rome. But in a few years after, when Carneades, Critolaus, and Diogenes, who were not only philofophers but orators, came ambaffadors from Athens to Rome; the Roman youth were fo charmed with the eloquence of their harangues, that \ they could no longer be dopt from purfuingthe dudy of oratory. And by a further acquaintance with the Greeks, it foon gained fuch edeem, that perfons of the fird quality employed their time and pains to ac¬ quire it. And a young gentleman, who was ambi¬ tious to advance himfelf in the fervice of his country, could have little hopes of fuccefs, unlefs he had laid the foundation of his future profpedls in that dudy. Seneca tells us, that Lucius Plotius, a Gaul, was the fird who taught the art of oratory at Rome in Latin ; which Cicero fays, was while he was a boy ; ; and when the mod dudious perfons went to hear him, he lamented that he could not go with them ; being prevented by the regard he paid to the opinion of fome of his friends, who thought that greater improvements were made by exercifes in the Greek language under Grecian maders. Seneca adds, that this profdfion j continued for fome time in the hands of freedmen* and that the fird Roman who engaged in it was Blan- dus of the equedrian order, who was fucceeded by j others ; fome of whofe lives are yet extant, written by Suetonius, as many of the Grecians are by Philodra- tus and Eunapius. Quintilian likewife gives us the names of thofe among the Romans, who wrote upon l the art. ‘ The fird (fays fie) as far as I can learn, who compofed any thing upon this argument, was M. Cato the cenfor. After him Anthony the orator be¬ gan upon the fubjedl, which is the only work he has left, and that imperfedl. Then followed fome of lefs note. But he who carried eloquence to its highed { pitch among us, was Cicero ; who has likewife by his - rules given the bed plan both to pra&ife and teach the art. After whom modedy would require us to men¬ tion no more, had he not told us himfelf, that his books of rhetoric dipt out of his hands, while he was but a youth. And thofe lefler things, which many perfons want, he has purpofely omitted in his dif- courfes of oratory. Cornificius wrote largely upon the fame fubjecl; Stertinius and Gallic the father, each of them fomething. But Celfus and Lenas were more accurate than Gallio; and in our times Virginius, Pliny, and Rutilius. And there are at this day fome celebrated authors of the fame kind, who, if they had taken ntrod. ORATORY. taken in every thing, might have faved my pains.’ Time has fince deprived us of moll of the writers men¬ tioned here by Quintilian. But we have the lefs rea- fon to regret this lofs, fince it has preferved to us Ci¬ cero’s treatifes upon this fubjedl ; which we may well fuppofe to have been chiefly owing to their own excel¬ lency, and the great efteem they have always had in the world. Befides his Thw books of Invention, which Quintilian here calls his Books of Rhetoric, there are extant of his, Three books of an Orator; one Offasnous Orators; and another, which is called The Orator; as alfo his Topics, a preface Concerning the leji fort oj Orators, and a treatife Of the parts of Oratory. Each of which treatifes, whether we regard thejuftnefs and delicacy of the thoughts, the ufefulnefs of the rules, or the elegance and beatity of the flyle, deferve to be frequently perufed by all who are lovers of eloquence. For who can be thought fo well qualified to give the rules of any art, as he who excelled all mankind in the pra&ice of them ? But thofe Four books to Herennitts, which are publilhed among Cicero’s works, feem with good reafon to be attributed to Cornificius, whom Quintilian here mentions. And Celfus is by fome af¬ firmed to have taught oratory, wdiom he alfo places among the rhetoricians, and whofe Eight books of Me¬ dicine are yet extant, written in fo beautiful a ftyle as plainly fhews him to be a mailer of eloquence. But Quintilian himfelf outdid all who w’ent before him in diligence and accuracy as a writer. His Inf'stations are fo comprehenfive, and written with fuch great ex- aftnefs and judgment, that they are generally allow¬ ed to be the moil perfeA work of the kind. With this excellent author we fliall fini/h the account of the La¬ tin rhetoricians. There were indeed fome others in the following ages, whofe works are yet extant; but as they con¬ tain nothing of moment, which is not to be found in thofe already mentioned, we fliall forbear to name them. Much lefs fhall we defcend to that numerous body of writers, who fince the revival of learning have treated upon this fubjedl, for the fame reafon. And UchbP. a very good judge* has not long fince given it as his Cam- opinion, that the method of forming the bell fyftem y, Lett. 0f oratory, is to colleft it from the fineft precepts of J13' Ariftotle, Cicero, Quintilian, Longinus, and other celebrated authors; with proper examples taken from the choiceft parts of the pureft antiquity. And this is the method attempted to be purfued in the follow¬ ing treatife. $ 2. Of the Nature of Oratory. The terms and oratory, having no other dif¬ ference but that one is taken from the Greek language and the other from the Latin, may be ufed promifcu- oufly; but the cafe is not the fame with refped to the words rhetorician and orator. For although the Gre- cians ufed the former, both to exprefs thofe who taught 'the art, and thofe who pradtifed it; yet the Romans afterward, when they took that word into their lan¬ guage, confined it to the teachers of the art, and call¬ ed the reft orators. And there feems to have been a fufficient reafon for this diftin&ion, fince the art was the fam«s in both, and might therefore go by either name ; but the different province of rhetoricians and orators made it not improper they Ihould be called by different names. Befides, anciently, before rheto¬ ric was made a feparate and diftindl art from philofo- phy, the fame perfons taught both. And then they were called not only rhetoricians, but fophifs. But becaufe they often employed their art rather to vindi¬ cate what was falfe and unjuft, than to fupport truth and virtue: this difingenuous conduS, by which they frequently impofed upon weak minds, brought a dif- credit both upon themfelves and their profeifion. And therefore the name fophif, or fophifer, has been more generally ufed in an ill fenfe, to fignify one fkilled ra¬ ther in the arts of cavilling, than qualified to fpeak well and accurately upon any fubjeft. It is not neceffary to ufe many words, to prove that oratory is an art. For it is comprifed under certain rules, agreeable to reafon, delivered in a regular me¬ thod, and fuited to attain the end it propofes; which are chara&ers fufficient to denominate it an art. In¬ deed the cafe is the fame here, as in moft other things, that a good genius is of itfelf more fcrviceable, than the moft exa6l acquaintance with all the rules of art, where that is wanting. But it is fufficient that art help nature, and carry it farther than it can other- wife advance without it. And he who is defirous to gain the reputation of a good orator, will find the af- fiftance of both very neceffary. Some perfons have thought, that many of the common fyftems written up¬ on the fubjeft of oratory have been attended with this inconvenience, that by burdening the mind with too great a number of rules about things of lefs import¬ ance, they have oftentimes rather difcouraged than promoted the ftudy of eloquence. This undoubtedly is extreme which fhould be always carefully avoided. But however, an indifferent guide in a ftrange road is better than none at all. It may be worth while to hear Quintilian’s opinion upon this head.. 4 I would not (fays he) have young perfons think they are fuf- ficiently inftrudted, if they have learned one of thofe compends which are commonly handed about, and fancy themfelves fafein the decrees, as it were, of thefe technical writers. The art of fpeaking requires much labour, conftant ftudy, a variety of exercife, many trials, the greateft prudence, and readinefsof thought. However, thefe treatifes are ufeful, when they fet you in a plain and open way, and do not confine you to one narrow trad, from which he who thinks it a crime to depart muft move as flowly as one that walks upon a rope.” We fee he is not for having us confine ourfelves too clofely to fyftems, though he thinks they are of fervice at firft,. till ufe and experience render them lefs neceffary. The bufinefs of oratory is to teach us to fpeak well; which, as Cicero explains it, is to {peak jufly, metho¬ dically, floridly, and copioufly. Now, in order to fpeak juflly, or pertinently, a per- fon muft be mafter of his fubjcd, that he may be able to fay all that is proper, and avoid whatever may ap¬ pear foreign and trifling. And he muft clothe his thoughts with fuch words and expreffions, as are moft fuited to the nature of the argument, and will give it the greateft force and evidence. And as it teaches to fpeak juftly, fo likewife metho¬ dically. This requires, that all the parts of a difcourfe be placed in their proper order, and with fuch juft con¬ nection, as to relied a light upon each other, and; thereby, 5645 5646 ORATORY. thereby to render the whole both clear in itfelf, and eafy to be retained. But the fame method is not pro¬ per for all difcourfes. Arid very frequently a different manner is convenient in handling the fame fubjeft. For it is plain, that art, as well as nature, loves va¬ riety ; and it difcovers the fpeaker’s judgment, when the difpofttion of bis difcourfe is fo framed, as to ap¬ pear eafy and natural, rather than the effed of indu- Itry and labour. To fpeak floridly, is fo peculiar a property of this art, that fome have wholly confined it to the pomp and ornaments of language. But that it extends far¬ ther, and refpe&s things as well as words, we (hall have occafion to Ihew hereafter. It contains indeed the whole fubjed of elocution, but does not wholly confift in it. True and folid eloquence requires not only the beauties and flowers of language; but like- wife the belt fenfe and cleareft reafoning. Befides, rhe¬ toric gives rules for the feveral forts of flyle, and di- reds the ufe of them agreeably to the nature of the fubjed. But the force of oratory appears in nothing more, than a oopioufnefs of expreffion, or a proper manner of enlargement, fuited to the nature of the fubjed; which is of great ufe in perfuafion, and forms the laft property, required by Cicero, of fpeaking well. A fhort and concife account of things is often attended with obfcurity, from an omiffion of fome neceffary cir- cumftances relating to them. Or, however, where that is not the cafe, yet for want of proper embellilhments to enliven the difcourfe, and thereby to excite and fix the hearers attention, it is apt to flip through their minds without leaving any impreffion. But where the images of things are drawn in their full proportion, painted iu their proper colours, fet in a clear light, and reprefented in different views, with all the ftrength and beauties of eloquence, they captivate the minds of the audience with the higheft pleafure, engage their attention, and by an irrefiftible force move and bend them to the defign of the fpeaker. The principal end and defign of oratory is to per- fuade. For which reafon it is frequently called the art ef perfuafion. Indeed the orator has often other fub- ordinate views; as when he endeavours either to de¬ light his hearers with what is pleafant and agreeable, ©r to concilitate their good opinion by a fmooth and artful addrefs: but ftill both thefe are in order to per- fuade and excite them to action. And while the orator employs his art in purfuing only thofe ends for which it was at firft defigned, the perfuading men to good and virtuous actions, and dif- fuading them from every thing that is ill and vicious; nothing can be more commendable in itfelf, or ufeful to human focieties. § 3. Of the Divifon of Oratory. Oratory confifts of four parts; invention, difpofi- tion, elocution, and pronunciation. This will appear by confidering the nature of each of them, and what it contributes in forming an orator. Every one who aims to fpeak well and accurately upon any fubjedt, does naturally in the firft place inquire after and pur. fue fuch thoughts as may feem molt proper to explain and illuftrate the thing upon which he defigns to dif¬ courfe. And if the nature of it requires that he flrould bring reafons to confirm what he fays, he not only feeks the ftrongeft, and fuch as are like to be beft re¬ ceived; but alfo prepares to anfwer any thing which may be offered to the contrary. This is invention. After this he deliberates with himfelf in what method to difpofe of thofe things which have occurred to his mind, that they may appear in the plaineft light, and not lofe their force by diforder and confufion. This is the bufinefs of difpofttion. His ne^t concern is to give his thoughts an agreeable drefs; by making choice of the. fitteft words, cleareft expreffions, fmootU and harmonious periods, with other ornaments of ftyle, as may beft fuit the nature of his fubjeft, brighten his difeourfe, and render it moft entertaining to his hear¬ ers. And this is called elocution. The laft thing he attends to, is to deliver what he has thus compofed, with a juft and agreeable pronunciation. And daily experience convinces us, how much this contributes both to engage the attention, and imprefs what is fpo- ken upon the mind. This then is the method to which .nature diredts, in order to qualify ourfelves fordifeour- fing to the beft advantage: Though by cuftom and habit thefe things become fo familiar to us, that we do not always attend to them feparately in their na¬ tural order. However, it is the bufinefs of art to fol¬ low nature, and to treat of things in that manner which Are di&ates. PartI. Of INVENTION. Chat. I. Of Invention in general; and particu¬ larly of Common Places, and State of a Caufe. Nvention, confidered in general, is the difeovery of fuch things as are proper to perfuade. And in order to attain this end, the orator propofes to him¬ felf three things: To prove or iliuftrate the fubjeft up¬ on which he treats; to conciliate the minds of his hear¬ ers; and to engage their paffions in his favour. And as thefe require different kinds of arguments or mo¬ tives, invention furnifhes him with a fupply for each of them, as will be fhewn in their order. An argument, as defined by Cicero, is a reafon, which induces us to believe, what before we doubted o£ And as different kinds of difcourfes require different arguments, rhetoricians have confidered them two ways; in general, under certain heads, as a common fund for all fubje&s; and in a more particular manner, as they are fuited to donor fir at ive, deliberative, or ju¬ dicial difcourfes. At prefent we (hall treat only upon the former of tbefe. And now, that one thing may receive proof and confirmation from another, it is ne¬ ceffary that there be fome relation between them; for all things are not equally adapted to prove one ano¬ ther. Thus, in meafuring the quantity of two things which we would ftrew, to be either equal or unequal, if they are of fuch a nature that one cannot be applied to the other, then we take a third thing, which may be applied to them both; and that muft be equal at leaft Organ. yLafe ( TTtXS:. y. orrery. Plate CCXXSIt. Part I. ORATORY. 5^47 fnyention. lead to one of the two, which if applied to the other, I and found equal to that alfo, we prefently conclude that thofe two things are equal; but if it be unequal to the other, we fay that thofe two things are un¬ equal. Becaufe it is the certain and known property of all quantities, that whatfoever two things are equal to a third, are equal to one another; and where one of any two things is equal to a third, and the other unequal, thofe two things are unequal to one another. What has been faid of quantities, will hold true in all other cafes, that fo far as any two things or ideas agree to a third, fo far they agree to one another. So likewife, on the contrary, as far as one of any two things or ideas does agree to a third, and the other does not, fo far they difagree with one another; in which refpeft, one of them cannot be truly affirmed of the other. Since, therefore, in every propofition, one thing is fpoken of another, if we would find out whe¬ ther the two ideas agree to each other or not, where this is not evident of itfelf, we muft find out fome ! . third thing, the idea of which agrees to one of them; and then that being applied to the other, as it does agree or difagree with it, fo we may conclude, that the two things propofed do agree or difagree with one another. This will be made more clear by an example or two. Should it be inquired, Whether virtue is to he loved; the agreement between virtue and love might be found by comparing them fepa- rately with happinefs, as a common meafure to both. For fince the idea of happinefs agrees to that of love, and. the idea of virtue to that of happinefs; it follows, that the ideas of virtue and love agree to one another: and therefore it may be affirmed, That virtue is to be loved. But on the contrary, becaufe the idea of mi- fery difagrees with that of love, but the idea of vice agrees to that of mifery, the two ideas of vice and love muft; confequentiy difagree with one another; and therefore it would be falfe to affert, That vice is to he loved. Now, this third thing logicians call the mediusn, or middle term, becaufe it does as it were connect two extremes; that is, both parts of a pro¬ pofition. But rhetoricians call it an argument, be¬ caufe it is fo applied to what was before propofed, as to become the inftrument of procuring our affent to it. Thus far as to the nature and ufe of arguments. We Ihall next explain by what methods they are to be fought. A lively imagination, and readinefs of thought, are undoubtedly a very great help to invention. Some perfons are naturally endued with that quicknefs of fancy, and penetration of mind, that they are feldom at a lofs for arguments either to defend their own opinions, or to attack their adverfaries. However, thefe things being the ^ift of nature, and not to be gained by art, do not properly fall under our prefent confideration. It will be readily granted, that great learning and extenfive knowledge are a noble fund for invention. An orator therefore fhould be furnilhed with a (lock of important truths, folid maxims of reafon, and a variety of knowledge, colle&ed and treafured up both from obfervation, and a large acquaintance with the liberal arts ; that he may not only be qualified to exprefs himfelf in the moft agreeable manner, but likewife to fupport what he fays with the ftrongeft and cleareft arguments. Vox.. VIII. 2 But becaufe all are hot born with a like happy Invention* genius, and have not the fame opportunity to cultivate their minds with learning and knowledge; and be¬ caufe nothing is more difficult than to dwell long upon the confideration of one thing, in order to find out the ftrongeft arguments which may be offered for and againft it; upon thefe accounts, art has preferibed a method to leffen, in fome meafure, thefe difficulties, and help every one to a fupply of arguments upon any fubjeft. And this is done by the contrivance of com¬ mon places, which Cicero calls the feats or heads of arguments, and by a Greek name topics. They are of two forts, internal and external. I. Internal topics. Though things, with regard to 3 their nature and properties, are exceedingly various, yet they have certain common relations, by means whereof the truth of what is either affirmed or denied concerning them in any refpeft may be evinced. The ancient Greek rhetoricians therefore reduced thefe re¬ lations to fome general heads, which are termed com¬ mon places; becaufe the reafons or arguments fuited to prove any propofition, are repofited in them, as a common fund or receptacle. And they are called in¬ ternal heads, becaufe they arife from the fubjeft upon which the orator treats; and are therefore diftinguilhed from others named external, which he fetches from without, and applies to his prefent purpofe, as will be Ihewn hereafter. Cicero and Quintilian make them 16; three of which comprehend the whole thing they are brought to prove, namely, definition, enumerationt and notation; of the remaining 13, fome contain a part of it, and the reft its various properties and cir- cumftances, with other confiderations relating to it; and thefe are, genus, fpecies, antecedents, confequents, adjuncts, conjugates, caufe, effett, contraries, oppofites, fmilitude, dijjmilitude, and comparifon. Definition explains the nature of the thing defined, and ffiews what it is. And to whatfoever the defini¬ tion agrees, the thing defined does fo likewife. If therefore Socrates be a rational creature, he is a man; becaufe it is the definition of a man, that he is a ra¬ tional creature. Enumeration takes in all the parts of a thing. And from this we prove, that what agrees to all the parts, agrees to the whole; and what does not agree to any one or more parts, does not agree to the whole: As when Cicero proves to Pifo that all the Roman (late hated him, by enumerating the feveral ranks and orders of Roman citizens who all did fo. Notation, or etymology, explains the meaning or fignification of a word. From which we reafon thus: “ If he cannot pay his debts, he is infolvent;” for that is the meaning of the word insolvent. Genus is what contains under it two or more forts of things, differing in nature. From this head logi¬ cians reafon thus: “ Becaufe every animal is mortal, and man is an animal, therefore man is mortal.” But orators make a further ufe of this argument, which, they call afeending from the hypothejis to the thejis; that is, from a particular to a general: As ffiould a per- fon, when fpeaking in praife of juftice, take occafion from thence to commend and (hew the excellency of virtue in general, with a view to render that particular virtue more amiable. For fince^every fpecies contains in it the whole nature of the genus to which it relates, befides what is peculiar to.itlelf, whereby it is diftin- 31 Y guifhed 5648 O R A T Invention. guHhed from it; what is affirmed of the genus, muft — of neceffity be applicable to the fpecies. Species is that which comprehends under it all the individuals of the fame nature. From hence we may argue, “ He is a man, therefore he has a rational foul.” -And orators fometimes take occafion from this head to defcend from the thefis to the hypothefis: that is, in treating upon what is more general, to in¬ troduce fome particular contained under it, for the greater illuftration of the general. Antecedents are fuch things, as, being once allowed, others neceffarily, or very probably, follow. From this head an infeparable property is proved from its fubjeft: as, It is material, and therefore corruptible. Confeqiients are fuch things, as being allowed, ne- ceflatily, or very probably infer their antecedents. Hence the fubjedl is proved from an infeparable pro¬ perty in this manner: It is corruptible, and therefore material. Adjuncts are feparable properties of things, or cir^ cumftances that attend them. Thefe are very nume¬ rous, and afford a great variety of arguments, fome of which ufually occur in every difcourfe. They do not neceffarily infer their fubjeA; but, if fitly chofen, render a thing credible, and are a fufficient ground for affent. The way of reafoning from them we lhall fhew prefently. Conjugates are words deduced from the fame origin ■with that of our fubject. By thefe the habit is proved from its a&s : as, He who does juftly is juft. He does not a£t wifely, therefore he is not wife. But this infe¬ rence will not hold, unlefs the aftions appear continued and conftant. A caufe is that, by the force of which a thing does exift. There are four kinds of caufes, matter, form, efficient, and end, which afford a great variety of ar¬ guments. The way of reafoning from them is to in¬ fer the effeft from the caufe : as, Man is endued with reafon, therefore he is capable of knowledge. An effed is that which arifes from a caufe, there¬ fore the caufe is proved by it: as, He is endued with knowledge, therefore with reafon. Contraries are things, which under the fame genus are at the utmoft diftance from each other. So that what we grant to the one, we utterly deny the other : as, Virtue ought to be embraced, therefore vice fhould be avoided. Qppofites are fuch things, which, though repugnant to each other, yet are not dire&ly contradiflory : as, To love and to injure, to hate and to commend. They differ from contraries in this, that they do not abfo- lutely exclude one another. An argument is drawn from things repugnant, thus : He will do a man a mif- chief, therefore he does not love him. He loves a man, therefore he will not reproach him. Similitude is an agreement of things in quality. Thus Cicero proves, that pernicious citizens ought to be taken out of the ftate; by the likenefs they bear to corrupted members, which are cut off to prevent fur¬ ther damage to the body. Dijfimilitude is a difagreeraent of things in quality. From this head Cicero fhews the preference of his own exile to Pifo’s government of Macedonia ; by the dif¬ ference between their conduit, and the people’s efteem of them.. ’ O R Y. Part II Companion is made three ways: for either a thing Iiventk?; e is compared with a greater, with a lefs, or with its equal. This place, therefore, differs from that of fimilitude on this account, that the quality was confi- dered in that, but here the quantity. An argument from the greater is thus drawn : If five legions could j| not conquer the enemy, much lefs will two. We (hall juft give one example of the manner of 4 reafoning from thefe heads, whereby the ufe of them '| may further appear. If any one, therefore, fhould ; f have endeavoured to perfuade Cicero not to accept of his life upon the condition offered him by Antony, * That he would burn his Philippic orations which had || been fpoken againft him, he might be fuppofed to 1 ufe fuch arguments as thefe; partly taken from the adjun&s of Cicero, partly from thofe of Antony, and partly from the thing itfelf. And firft with regard to i| Cicero, it might be faid, That fo great a man ought >:| not to purchafe his life at fo dear a price as the lofsof that immortal honour which by fo great pains and labour he had acquired. And this might be confirm- jB ed by another argument, That now he was grown 1 old, and could not expeft to live much longer. And jl frem the chara&er of Antony he might argue thus: 1 That he was very crafty and deceitful; and only de- figned, by giving him hopes of life, to have the Phi¬ lippics firft burnt, which otherwife he knew would tranfmit to pofterity an eternal brand of infamy upon 1 him ; and then he would take off the author. And 1 this might be ftiewn by comparifon. For fince he |! would not fpare others, who had not fo highly exaf- perated him, and from whom he had not fo much to fear; cer*. inly he would not forgive Cicero, fince he knew well enough, that fo long as he lived, he him- .) fclf could never be in fafety. And, laftly, an argu¬ ment might alfo be fetched from the nature of the thing itfelf in the following manner : That Cicero by ? this adlion would fhamefully betray the ftate, and the caufe of liberty, which he had through his whole life J moft couragioufly defended, with fo great honour to himfelf, and advantage to the public. Upon fuch an ; account, a perfon might have ufed thefe or the like arguments with Cicero, which arife from the fore- j mentioned heads. From this account of common places, it is eafy5—(l8i to conceive what a large field of difcourfe they open to the mind upon every fubjeft. Thefe different confiderations furnilh out a great number and variety j of arguments, fufficient to fupply the moft barren in¬ vention. He can never be at a lofs for matter, who confiders well the nature of his fubjeA, the parts of which it confifts, the circumftances which attend it, the caufes from whence it fprings, the effe&s it pro¬ duces, its agreement, difagreement, or repugnancy to other things ; and in like manner carries it through all the remaining heads. But although this method will affift us very much to enlarge upon a fubjeft, and place it in different views ; yet a prudent man is not fo defirous to fay a great deal, as to fpeak to the pur- pofe; and therefore will make choice of proper ar¬ guments, and fuch only as have a direct tendency to confirm or illuftrate his fubjedb. And for this end, it is neceffary for him to gain, firft a thorough know¬ ledge of his fubjedt, and then arguments will naturally - ; fpring up in his mind proper to fupport it: and if he Parti. O R A T Idvention. be ftil! at a loG, and find occafion to have recoiirfe to P~- thefe heads, he will readily perceive from whence to take thofe which are bed fuited to his pUrpofe. ' ig 11. Of external topics. When the orator reafons from fuch topics as do not arife froth his fubjeft, but from things of a different nature, thefe are called external. They are all taken from authorities, and are by one general name called TeJUmenies. Now a teftimony may be exprefled by writing, fpeech, or any other fign proper to declare a perfon’s mind. And all teftimonies may be diftinguifhed into two forts, divine and human. A divine teftirhony, when certainly known to be fuch, is incortteftable, and admits of no debate, but (hould be aCquiefeed in without hefitation. Indeed the anciertt Greeks ahd Romans efteemed the pretended oracles of their deities, ! the'anfwers of their augurs, and the like fallacies, di¬ vine teftimonies : but with us no one can be ignorant of their true notion, though they do not fo direftly come under our prefent confideration. Human tefti¬ monies, confidered as furnifhing the orator with ar¬ guments, may be reduced to three heads ; ’writings, •witnejfes, and contrails. i. By Writings, here, are to be underftood written laws, wills, or other legal inftruments, exprefied and conveyed in that manner. And it is not fo much the force and validity of fuch teftimonies, confidered in themfelves, that is here intended, as the occafion of difpute which may at any time arife concerning their true defign and import, when produced in proof upon either fide of a controverfy. And thefe are five; Am¬ biguity, Difagreement between the Words and inten¬ tion, Contrariety, Reafoning, and Interpretation. A writing is then faid to be ambiguous, when it is capable of two or more fenfes, which makes the wri¬ ter’s defign uncertain. Now ambiguity may arife ei¬ ther from Angle words, Or the conftruftion of fenten- ces. From Angle words ; as when either the fenfe of a word, or the application of it, is doubtful. As, fhould it be queftioned, whether ready money ought to be included under the appellation of chattels left by a will; or, if a teftator bequeath a certain legacy to his nephew Thomas, and he has two nephews of that name. But ambiguity is alfo fometimes occafioned from the conftru&ion of a fentence ; as when feveral things or perfofts having been already mentioned, it is doubtful to Which of them that which follows ought to be referred. For example, a perfon writes thus in his will: ‘ Let my heir give as a legacy to Titius, an horfe out of my ftable, which he pleafes.’ Here it may be queftioned, whether the word be refers to the heir or to Titius ; and confequently, whether the heir be allowed to give Titius which horfe he pleafe, or Titius may choofe which he likes beft. Now as to controverfres of this kind, in the firft cafe above-men¬ tioned, the party who claims the chattels may plead, that all moveable goods come under that name, and therefore that he has a right to the money. This he will endeavour to prove from fome inftances where the word has been fo ufed. The bufinefs of the op- pofite party is to refute this, by ihewing that money is not there included. And if either fide produce precedents in his favour, the other may endeavour to fhew the cafes are not parallel. As to the fecond cafe, arifing from an ambiguity in the name, if any other O R Y. 5649 words or expreflions in the will fcem to countenance Invention, either of the claimants, he will not fail to interpret ^ them to his advantage. So likewife, if any thing faid by the teftator, in his lifetime, or any regard fhewn to either of thefe nephews more than the other, may help to determine which of them was intended, a proper ufe may be made of it. And the fame maybe laid with regard to the third cafe. In which the le¬ gatee may reafon likewife from the common ufe of languige, and fhew, that in fuch expreffions, it is ufual to make the reference to the laft or next antece¬ dent; and from thence plead, that it was the defign of the teftator to give him the option. But in anfwer to this, it may be faid, that allowing it to be very often fo, yet in this inftance it feems more eafy and natural to repeat the verb give after pleafes, and fo to fupply the fentence, 'which be pleafes to give him, re¬ ferring it to the heir, than to bring in the verb choofe, which was not in the fentence before ; and fo, by fupplying the fenfe, •which he pleafes to choofe, to give the option to Titius. But where controverfies of this kind arife from a law, recourfe may be had to other laws where the fame thing has been exprefled with, greater clearnefs; which may help to determine the fenfe of the paflage in difpute. A fecond controverfy from writings is, when one party adheres to the words, and the other to what he aflerts was the writer’s intention. Now he who op- pofes the literal fenfe, either contends, that what he himfelf offers is the iimple and plain meaning of the writing, or that it mull be fo underftood in the parti¬ cular cafe in difpute. An inftance of the former is this, as we find it in Cicero. A perfon who died without children, but left a widow, had made this provifion in his will: “ If I have a fon born to me, he fhall be my heir.” And a little after; “ If my fon die before he comes of age, let Curius be my heir.” There is no fon born : Curius therefore fues for the eftate, and pleads the intention of the teftator, who defigned him for his heir, if he fhould have no fon who arrived at age ; and fays, there can be no reafon to fuppofe he did not intend the fame perfon for his heir if he had no fon, as if he fhould have one Who afterwards died in his minority. But the heir at law infifts upon the words of the will; which, as he fays, require, that firft a fon fhould be born, and afterwards die under age, before Curius can fucceed to the inheritance ; and there being no fon, a fub- ftituted heir, as Curius was, can have no claim where the firft heir does not exift, from whom he derives his pretcnfion, and was to fucceed by the appointment of the will. Of the latter cafe, rhetoricians give this ex¬ ample : “ It was forbidden by a law to open the city- gates in the night. A certain perfon notwithftand- ing, in time of War, did open them in the night, and let in fome auxiliary troops, to prevent their being cut off by the enemy, who was pofted near the town.” Afterwards, when the war was over, this perfon i$ arraigned, and tried for his life on account of this ac¬ tion. Now, in fuch a cafe, the profecutor founds hii charge upon the exprefs words of the law ; and pleads, that no fufficient reafon can be afligned for going contrary to the letter of it, which would be to make a new law, and not to execute one already made. The defendant, on the other hand, alleges, That the 31 Y 2 fa& 5650 O R A 1 invention, fa&he is charged with cannot, however, come within ' the intention of the law ; fince he either could not, or ought not, to have complied with the letter of it in that particular cafe, which mull therefore neceffarily be fuppofed to have been excepted in the defign of that law when it was made. But to this the profe- cutor may reply, That all fuch exceptions as are in¬ tended by any law, are ufually expreffed in it : and inftances may be brought of particular exceptions ex~ preffed in fome laws ; and if there be any fuch excep¬ tion in the law under debate, it fliould efpecially be mentioneJl. He may further add. That to admit of exceptions not expreffed in the law itfelf, is to ener¬ vate the force of all laws, by explaining them away, and in effeft to render them ufelefs. And this he may further corroborate, by comparing the law under debate with others, and confidering its nature and importance, and how far the public intereft of the flate is concerned in the due and regular execution of it; from whence he may infer, that (hould exceptions be admitted in other laws of lefs confequence, yet, how¬ ever, they ought not in this. Laftly, he may confi- der the reafon alleged by the defendant, on which he founds his plea, and lhew there was not that neceffity of violating the law in the prefent cafe, as is pretended. And this is often the more requifite, becaufe the party who difputes againft the words of the law, always en¬ deavours to fupport his allegations from the equity of the cafe. If, therefore, this plea can be enervated, the main fupport of the defendant’s caufe is removed. For as the former arguments are defigned to prevail with the judge, to determine the matter on this fide the queftion from the nature of the cafe; fo the in¬ tention of this argument is to induce him to it, from the weaknefs of the defence made by the oppofite party. But the defendant will, on the contrary, ufe fuch arguments, as may bell demonftrate the equity of his caufe, and endeavour to vindicate the faft from his good defign and intention in doing it. He will fay, That the laws have allotted punilhments for the commiffion of fuch fafts as are evil in. themfelves, or prejudicial to others ; neither of which can be char¬ ged upon the a&ion for which he is accufed : That no' law can be rightly executed, if more regard be had to the words and fyllables of the writing, than to the intention of the legiflator. To which purpofe, he may allege that direftion of the law itfelf, which fays, “ The law ought not to be too rigorofly inter¬ preted, mor the words of it drained ; but the true in¬ tention and defign of each pan of it duly confidered:” As alfo that faying of Cicero, “ What law may not be weakened and deftroyed, if we bend the fenfe to the words, and do not regard the defign and view of the legiflator ?” Hence he may take occafion to com¬ plain of the hardfhip of fuch a procedure, that no dif¬ ference ftiould be made between an audacious and wilful crime, and an honed or neceffary aftion, which might happen to difagree with the letter of the law, though not with the intent of it. And as it was ob- ferved before to be of confiderable fervice to the ac- cufer, if he could remove the defendant’s plea of equity; fo it will be of equal advantage to the de¬ fendant, if he can fix upon any words in the law, which may in the lead feem to countenance his cafe, fince this will take off the main force of the charge. POKY. Parti. The third controverfy of this kind is, when two inventio|tn writings happen to clalh with each other, or at leaft ~” feem to do fo. Of this Hermogenes gives the fol- lowing indance. One law enjoins: “ He who con- ! tinues alone in a (hip during a temped, fhall have the property of the {hip.” Another law fays, “ A difin- i herited fon fliall enjoy no part of his father’s edate.” | Now a fon, who had been difinherited by bis father, «' happens to be in his father’s fliip in a temped, and continues there alone, when every one elfe had de- ferted it. He claims the fliip by the former of thefe laws, and his brother tries bis right with him by the latter. In fuch cafes, therefore, it may fird be con¬ fidered, Whether the two laws can be reconciled.. j| And if that cannot be done, then, Which of them ap¬ pears more equitable. Alfo, Whether one be pofi- tive, and the other negative : becaufe prohibitions are a fort of exceptions to pofitive injunctions. Or, If one be a general law, and the other more particular, and come nearer to the matter in quedion, JLikewife, Which was lad made: fince former laws are often abrogated, either wholly or in part, by fubfequent laws; or at lead were defigned to be fo. Ladly, it may be obferved, Whether one of the laws be not plain and exprefs ; and the other more dubious, or has any ambiguity in it. All, or any of which things, that party will not omit to improve for his advantage whofe intered is concerned in it. The fourth controverfy is reafon'ing. As when fomething, not exprefsly provided for by a law, is in¬ ferred by a fimilitude, or parity of reafon, from what is contained in it. Quintilian mentions this indance of it. “ There was a law made at Tarentum, to pro¬ hibit the exportation of wool, but a certain perfon exports flieep.” In this cafe, the profecutor may fird compare the thing which occafions the charge, with the words of the law, and (hew their agreement, and how unneceffary it was that particular thing {hould have been exprefsly mentioned in the law, fince it is plainly contained in it, or at lead an evident con¬ fequence from it. He may then plead, that many things of a like nature are omitted in other laws for the fame reaion. And, ladly, he may urge the rea- fonabknefs and equity of the procedure. The de¬ fendant, on the other hand, will endeavour to fhew the deficiency of the reafoning, and the difference be¬ tween the two cafes. He will infill upon the plain and exprefs words of the law, and fet forth the ill tendency of fuch inferences and conclufions drawn from fimilitudes and comparifons, fince there is fcarce any thing but in fome refpeft may bear a refemblance to another. The lad controverfy under this head is interpreta¬ tion, in which the difpute turns upon the true mean¬ ing and explication of the law in reference to that particular cafe. We have the following indance of this in the Pandedls : “ A man who had two fons, both under age, fubditutes Titius as heir to him who {hould die lad, provided both of them died in their minority. They both perifli together at fea before they came to age. Here arifes a doubt, whether the fubditotion can take place, or the inheritance de¬ volves to the heir at law.” The latter pleads. That as neither of them can be faid to have died lad, the fubftitution cannot take place; which was fulpended, upon Parti. ORA': Invention, upon the condition that one died after the other. " But to this it may be faid, It was the intention of the teftator, that if both died in their nonage, Titius fliould fucceed to the inheritance; and therefore it makes no difference whether they died together, or one after the other: and fo the law determines it. 2. The fecond head of external arguments are Wit- vejfes. Thefe may either give their evidence, when ab- fent, in writing fubfcribed with their name ; or pre- fent, by word of mouth. And what both of them teftify, may either be from hearfay; or what they faw therafelves, and were prefent at the time it was done. As the weight of the evidence may be thought greater or lefs on each of thefe accounts, either party will make fuch ufe of it as he finds for his advantage. The characters of the witneffes are alfo to be confi- dered ; and if any thing be found in their lives or be¬ haviour that is juftly exceptionable, to invalidate their evidence, it ought not to be omitted. And how they are affeCted to the contending parties, or either of them, may deferve confideration ; for fome allowances may be judged reafpnable in cafe of friendfhip, or enmity, where there is no room for any other exception. But regard Ihould chiefly be had to what they teftify, and how far the caufe is affefted by it. Cicero is very large upon mod of thefe heads in his defence of Marcus Fon- teius, with a defign to weaken the evidence of the Gauls againft hiip. And where witnefles are produ¬ ced on one, fide only, as orators fometimes attempt to jeflen the credit of this kind of proof, by pleading, that witnefles fir.e liable to be corrupted, or biafled by fome prevailing intereft or paffion, to which argu¬ ments taken from the nature and circumftances of things are not fubjeCf; it maybe anfwered on the other hand, that fophiftical arguments and falfe co- Jourjhgs are not expofed to infamy or punifhment, whereas witnefles are reftrained by fhame and penal¬ ties, nor would the law require them if they were not neceffary. 3. The third and laft head of external arguments are Contracts; which may be either public or private. By public are meant the tranfaflions between different ftates, as leagues, alliances, and the like ; which de¬ pend on the laws of nations, and come more pro¬ perly unfler deliberative difcourfes, to which we fhall refer them. Thofe are called private, which re¬ late to leffer bodies or focieties of men, and Angle perfons1) and may be either written, or verbal. And it is not fo much the true meaning and purport of them that is here confidefed, as their force and obli¬ gation. And, as the Roman law declares, ‘ No¬ thing can be more agreeable to human faith, than that perfops fhduld ftand to their agreements.’ Therefore, in controverfies of this kind, the party, whofe inte¬ reft it is that the contradt fhould be maintained, will plead, that fuch covenants have the force of private laws, and ought religioufly to be obferved, fince the common affairs of mankind are tranfatfed in that man- nej^; and therefore to violate them, is to deftroy all commerce and fociety among men. On the other fide it may be faid, that juftice and equity are chiefly to be regarded, which are immutable j and befides, that the.publit laws are the common rule to determine fuch differences, which are defigned to redrefs thofe who are aggrieved. And, indeed, where a compaft has been obtained by force or fraud, it is in itfelf void, and r O R Y. 5651 has no effeft either in law or reafon. But on the other invention, hand, the Roman lawyers feem to have very rightly determined, that all fuch obligations as are founded in natural equity, though not binding by national laws, and are therefore called mida pafta, ought, however, in honour and confcience to be performed. Ill, Of the State of a Controverfy. The ancients, ob- 20 ferving that the principal queftion or point of dif- pute in all controverfies might be referred to fome par¬ ticular head, reduced thofe heads to a certain number; that both the nature of the queftion might by that means be better known, and the arguments fuited to it be difcovered with greater eafe. And thefe heads they call fates. By the ftate of a controverfy, then, we are to under- ftand the principal point in difpute between contend¬ ing parties, upon the proof of which the whole caufe or controverfy depends. Wc find it expreffed by feve- ral other names in ancient writers: as, the confitu- tion of the caufe, the general head, and the chief que- fion- And as this is the principal thing to be attend¬ ed to in every fuch difcourfe ; fo it is what firft re¬ quires the confideration of the fpeaker, and fhould be well fixed and digefted in his mind, before he proceeds to look for arguments proper to fupport it. Thus An¬ thony, toe Roman orator, fpeaking of his own me¬ thod in his pleading, fays : “ When I underftand the nature of the caufe, and begin to confider it, the firft thing I endeavour to do is, to fettle with myfelf what that is to which all my difcourfe relating to the mat¬ ter in difpute ought to be referred : then I diligently attend to thefe other two things, How to recommend myfelf, or thofe for whom I plead, to the good efteem of my hearers ; and how to influence their minds, as may beft fuit my defign.” This way of proceeding appears very agreeable to reafon and prudence. For what can be more abfurd, than for a perfon to attempt the proof of any thing, before he has well fettled in his own mind a clear and diftinft notion, what the thing is which he would endeavour to prove? Quin¬ tilian deferibes it to be, ‘ That kind of queftion which arifes from the firft conflift of caufes.’ In judicial cafes, it immediately follows upon the charge of the plain¬ tiff, and plea of the defendant. Our common law ex- preffes it by one word, namely, the ijfue. Which in¬ terpreters explain, by defcribing it to be, “ That point of matter depending in fuit, whereupon the par¬ ties join, and put their caufe to the trial.” Examples will further help to illuftrate this, and render it more evident. In the caufe of Milo, the charge of the Cio- dian party is, Milo Hilled Clodius. Milo’s pica or de¬ fence, 1 killed him, but jufly. From hence arifes this grand queftion, or ftate of the caufe: Whether it nvas lawful for Milo to kill Clodius P And that Clodius was lawfully killed by Milo, is what Cicero in his defence of Milo principally endeavours to prove. This is the main fubjedl of that fine and beautiful oration. The whole of bis difcourfe is to be confidered as centering at laft in this one point. Whatever different matters are occafionally mentioned, will, if clofely attended to, be found to have been introduced tome way or other the better to fupport and carry on this defign. Now in fuch cafes, where the faft is not denied, but fomething is offered in its defence, the ftate of the caufe is taken from the defendant’s plea, who is obli¬ ged to make it good : As in the inftance here given. 5%2 Invention, the chief point in difpute was the lawfulnefs of Milovs adtion, which it was Cicero’s bufinefs to demonftrate. But when the defendant denies the fadt, the ftate of the caufe arifes from the accufation; the proof of which then lies upon the plaintiff, and not, as in the former cafe, upon the defendant. So in the caufe of Rofcius, the charge made againft him is. That he killed his father. But he denies the fa ft. The grand queftion therefore to be argued is: Whether or not he killed his father ? The proof of this lay upon his ac- cufers. And Cicero’s defign in his defence of him is to fhew, that they had not made good their charge. But it fometimes haippens, that the defendant neithet1 abfolutely denies the faft, nor attempts to juftify it j but only endeavours to qualify it, by denying that it is a crime of that nature, or deferves that name, by which it is exprefled in the charge. We have an ex¬ ample of this propofed by Cicero: “ A perfon is ac- cufed of facrilege, for taking a thing, that was facred, out of a private houfe. He owns the faft, but denies it to te facrilege ; fince it was committed in a private houfe, and not in a temple.” Hence this queftion arifes : Whether to take a facred thing out of a private houfe, is to be deemed facrilege, or only fsmple theft? It lies upon the accufer to prove what the other denies; and therefore the ftate of the caufe is here alfo, as well as in the preceding cafe, taken from the indift- ment. But befides the principal queftion, there are other fubordinate queftions, which follow upon it in the courfe of a difpute, and fhould be carefully diftin- guifhed from it. Particularly that which arifes from the reafon, or argument, which is brought in proof of the principal queftion. For the principal queftion it- fdf proves nothing, but is the thing to be proved, and becomes at laft the conclufion of the difcourfe. Thus, in the caufe of Milo, his argument is: I killed Clo- dius jufly, becaufe he ajfajfmated me. Unlefs the Clo- dian party be fuppofed to deny this, they give up their caufe. From henpe therefore this fubordinate queftion follows : Whether Clodius ajfajfinated Milo ? Now Ci¬ cero fpends much time in the proof of this, as the hinge on which the firft queftion, and confequently the whole caufe, depended. For if this was once made to appear, the lawfulnefs of Milo’s killing Clodius, which was the grand queftion or thing to be proved, might be inferred as an allowed confequence from it. This will be evident, by throwing Milo’s argument, as ufed by Cicero, into the form of a fyllogifm. Jin affajfinator is lawfully killed: Clodius was an affafmator : Therefore he was lawfully killed by Milo, whom he ajfafinated. If the minor propofition of this fyllogifm was granted, no one would deny the conclufion : for the Roman law allowed of felf-defence. But as Cicero was very fenfible this would not be admitted, fo he takes much pains to bring the court into the belief of it. Now where the argument brought in defence of the fecond queftion is contefted, or the orator fuppofes that it may be fo, and therefore fupports that with another argument, this occafions a third queftion confequent upon the former ; and in like manner he may proceed to a fourth. But be they more or fewer, they are to be confidered but as one chain of fubordinate queftions I Part I dependent upon the firft. And though each of them Invemioi has its particular ftate, yet none of thefe is what rhe^ toricians call The fate of the Caufe, which is to be un- f j derftood only of the principal queftion. And if, as it frequently happens, the firft or principal queftion is itfelf diredlly proved from mott than one argument; • this makes no other difference, but that each of thefe arguments) fo far as they are followed by others to ' fupport them, become a diftimfl feries of fiibordinat^ |‘ queftions, all dependent upon the firft:. As when Ci- ,1 cero endeavours to prove, that Rofcius did not kill his father, from two reafons or arguments: Becaufe he had neither any caufe to move him to fuch a barbarout aillion, nor any opportunity for it. Moreover, befides thefe fubordinate queftions, there are alfo incidental ones often introduced, which have fome reference to the principal queftion, and contri- i I bute towards the proof it, though they are not ntcef- farily connedted with it, or dependent upon it. And each of thefe alfo has its ftate, though different from that of the caufe. For every queftion, or point of con- * I troverfy, mu ft be ftated, before it can be made the ij fubjedl of difputation. And it is for this reafon, that :l every new argument advanced by an orator is'called a queftion; becaufe it is confidered as a frefh matter of controverfy. In Cicero’s deffertte of Milo, we rifteet with feveral of this fort of queftions, occafioned by fome afperfions which had been thrown out by thd I Clodian party to the prejudice of Milo, As, “ That he was unworthy to fee the light, who owned he had ;| killed a man :” For Milo before his trial had openly confeffed he killed Clodius. Sd likewrfe, “ That the fenate had declared the killing of Clbdius was an ille¬ gal adtion.” And further, “ That Pcihjiey, by ma¬ king a new law to fettle the manner of Milo’s trial, had given his judgment againft Milo.” Now to each | of thefe Cicero replies, before he proceeds to the prin¬ cipal queftion. And therefore, though the queltiort, in which the ftate of a controverfy confifts, is faid by Quintilian to arife from “ the firft conflidl of caufes,” yet we find by this inftance of Cicero, that it is not always the firft queftion in order, upoft Which the bra- : tor treats. But it fometimes happens, that the fame ckufe of j controverfy contains in it more than one ftate. Thus in judicial caufes, every diftindl charge occafions a new ] ftate. All Cicero’s orations againft Verres relate to one caufe, founded upon a law of the Romans againft unjuft exadlions made by their governors of provinces upon the inhabitants; but as that profecution i's iilade j up of as many charges as there are orations, every charge, or indidment, has its different ftate. So like- wife his oration in defence of Ccelius has two ftates, in - ; anfwer to a double charge made againft him by his adverfaries : one, “ for borrowing money of Clbdia, . in order to bribe certain flaves to kill a foreign ambaf- fador;” and the other, “ for an attempt afterward to poifon Clodia herfelf.” Befides which, there were fe¬ veral other matters of a lefs heinous nature, which Had been thrown upon him by his accufers, with a defign, very likely, to render the two principal charges more credible; to which Cicero firft replies, in the fame man¬ ner as in his defence of Milo. Though all the examples we have hitherto brought to illultrate this fubjed, have been taken from judicial cafes; ORATORY. on I. O R A T O . cafes ; yet not only tiiefe, but very frequently dif. “■courfes of the deliberative kind, and fometimes thofe of the deraonftrative, are managed in a controverfial way. And all controverfies have their ftate. And therefore Quintilian very juftly obferves, that “ dates belong both to general and particular queftions; and to all forts of caufes, demonllrative, deliberative, and judicial.” In Cicero’s oration for the Manilian law, this is the main point in difpute between him, and thofe who oppofed that law; “ Whether Pompey was the fitted perfon to be intruded with the management of the war againd Mithridate-sr” This is a fubjeft of the deliberative kind. And of the fame nature was that debate in the fenate, concerning the demolition of Carthage. For the matter in difpute between Cato, who argued for it, and thofe who were of the contrary opinion, feems to have been this: “ Whether it was for the intered of the Romans to demolifh Carthage?” And fo likewife in thofe two fine orations of Cato and Caefar, given us by Sallud, relating to the confpira- tors with Catiline, who were then in cudody, the con- troverfy turns upon this: “ Whether thofe prifoners fhould be punidied with death, or perpetual impriion- ment?” Examples of the demondrative kind are not fo common; but Cicero’s oration concerning the ‘ An- fwers of the foothfayers,’ may afford us an indance of it. Several prodigies had lately happened at Rome, upon which the fpothfayers being confulted, afligned this as the reafon of them, Becaufc fome places confe- crated to the gods had been afterwards converted to civil ufes. Clodius charged this upon Cicero; whofe houfe was rebuilt at the public expence, after it had been demolifhed by Clodius, and the ground confe- crated to the goddefs Liberty. Cicero in this ora¬ tion retorts the charge; and (hews, that the prodigies did not refpeft him, but Clodius. So that the quedion in difpute was: “ To which of the two thofe prodi¬ gies related ?” This oration does not appear to have been fpoken in a judicial way, and mud therefore be¬ long to the demondrative kind. His inveftive againd: Pifo is likewife much of the fame nature, wherein he compares his own behaviour and conduft with that of Pifo. As to the number of thefe dates, both Cicero and Quintilian reduce them to three. “ We mud (fays Qumtilian) agree with thofe, whofe authority Cicero follows, who tell us, that three things may be inqui¬ red into in all difputes : Whether a thing is; what it is; and how it is. And this is the method which na¬ ture preferibes. For in the fird place, it is neceflary the thing fhould exid, about which the difpute is: be- caufe no judgment can be made either of its nature, or quality, till its exidence be manifed; which is there¬ fore the fird quedion. But though it be manifed that a thing is, it does not prefently appear what it is; and when this is known, the quality yet remains: and af¬ ter thefe three are fettled, no further inquiry is necef- fary.” Now the fitd of thefe three dates is called the cmjetturalJlate; as if it be inquired, “ Whether one perfon killed another?” This always follows upon the denial of a fact, by one of the parties; as was the cafe of Rofcius. And it receives its name from hence, that the judge is left, as it were, to conjecture, whether the fa£t was really committed or not, from the evi¬ dence produced, on the other fide. The fecond is call- R Y. 5653 ed the definitive, fiate, when the faft is not denied; but Invention, the difpute turns upon the nature of it, and what name” is proper to give it: as in that example of Cicero, “ Whether to take a facred thing out of a private houfe be theft, or facrilege?” For in this cafe it is neceffary to fettle the didinCt notion of thofe two crimes, and (hew their difference. The third is called the Jlate of quality; when the contending parties are agreed both as to the fad, and the nature of it; but the difpute is, “ Whether it be jud or unjud, profitable or unprofi¬ table, and the like;” as in the caufe of Milo. From what has been faid upon this fubjeCI, the ufe of it may in a good meafure appear. For whoever en¬ gages in a controverfy, ought in the fird place to cbn- fider with himfelf the main quedion in difpute, to fix it well in his mind, and keep it condantly in his view; without which he will be very liable to ramble from the point, and bewilder both himfelf and his hearers. And it is no lefs the bufinefs of the hearers principally to attend to this; by which means they will be help¬ ed to didinguifh and feparate from the principal que¬ dion what is only incidental, and to obferve how far the principal quedion is affe&ed by it ; to perceive what is offered in proof, and what is only brought in for ilfudration; not to be mifled by digreffions, but to difeern when the fpeaker goes off from his fubjedl, and when he returns to it again ; and, in a word, to accompany him through the whole difeourfe, and carry with them the principal chain of reafoning upon which the caufe depends, fo as to judge upon the whole, whe¬ ther he has made out his point, and the conclufion follows from the premifes. Chap. II. Of Arguments fuited to Demonjirative Difcourjes. These confid either in praife or difpraife; and, 21 agreeably to the nature of all contraries, one of them will ferve to illudrate the other. Now we either praife perfons or things. I. In praifing or difpraifing perfor.s, rhetoricians preferibe two methods. One is, to follow the order in which every thing happened that is mentioned in the difeourfe; the other is, to reduce what is faid un¬ der certain general heads, without a drift regard to the order of time. 1. In purfuing the former method, the difeourfe may be very conveniently divided into three periods- The fird of which will contain what preceded the per- fon’s birth ; the fecond, the whole courfe of his life;; and the third, what followed upon his death. Under the fird of thefe may be comprehended what is proper to be faid concerning his country or family. And therefore, if thefe were honourable, it may be faid to his advantage, that he noways difgraced them, but afled fuitably to fuch a defeent. But if they were not fo, they may be either wholly omitted: or it may be faid, that, indead of deriving thence any advantage to his charafter, he has conferred a lading honour up¬ on them; and that it is not of fo much moment where,, or from whom, a perfon derives his birth, as how he lives. In the fecond period, which is that of his life, the qualities both of his mind and body, with his circum- ftances in the world, may be feparately confidered. Though, as Quintilian rightly obferves: “ All exter¬ nal 5^54 Invention. ORATORY. nal advantages are not pratfes for themfelves, but ac¬ cording to the ufe that is made of them. For riches, and power, and intereft, as they have great influence, and may be applied either to good or bad purpofes, are a proof of the temper of our minds; and therefore we are either made better or worfe by them.” But thefe things are a juft ground for commendation, when they are the reward of virtue, or induftry. Bodily endow¬ ments are health, ftrength, beauty, activity, and the like; which are more or lefs commendable, according as they are employed. And where thefe, or any of them, are wanting, it may be (hewn, that they are a- bundantly compenfated by the more valuable endow¬ ments of the mind. Nay, fometimes a defedt in thefe may give an advantageous turn to a perfon's charac¬ ter; for any virtue appears greater, in proportion to the difadvantages the perfon laboured under in exert¬ ing it. But the chief topics of praife are taken from the virtues and qualifications of the mind. And here the orator may confider the difpofttion, education, learning, and feveral virtues, which (hone through the whole courfe of the perfon’s life. In doing which, the preference fhould always be given to virtue above knowledge or any other accomplifhment. And in ac¬ tions, thofe are moft confiderable, and will be heard with greateft approbation, which a perfon either did alone, or firft, or wherein he had feweft affociates; as likewife thofe which exceeded expeftation, or were done for the advantage of others rather than his own. And further, as the laft fcene of a man’s life generally commands the greateft regard, if any thing remark¬ able at that time was either faid or done, it ought par¬ ticularly to be mentioned. Nor (hould the manner of his death, or caufe of it, if accompanied with any com¬ mendable circumftances, be omitted; as if he died in the fervice of his country, or in the purfuit of any other laudable defign. The third and laft period relates to what followed after the death of the perfon. And here the public lofs, and public honours conferred upon the deceafed, are proper to be mentioned. Sepulchres, ftatutes, and other monuments to perpetuate the memory of the dead, at the expence of the public, were in com¬ mon ufe both among the Greeks and Romans. But in the earlieft times, as thefe honours were more rare, fo they were lefs coftly. For as in one age it was thought a fufficient reward for him who died in the defence of his country, to have his name cut in a marble infcription, with the caufe of his death ; fo, in others, it was very common to fee the ftatues of gladi¬ ators, and perfons of the meaneft rank, ere&ed in public places. And therefore a judgment is to be formed of thefe things from the time, cuftom, and circumftances, of different nations ; fince the frequency of them renders them lefs honourable, and takes off from their evidence as the rewards of virtue. But, as Quintilian fays, “ Children are an honour to their parents, cities to their founders, laws to thofe who compiled them, arts to their inventors, and ufeful cuftoms to the authors of them.” And this may fuffice for the method of praifing perfons, when we propofe to follow the order of time, as Ifocrates has done in his funeral oration upon Eva- goras king of Salamis, and Pliny in his panegyric upon the emperor Trajan. But as this method is Part very plain and obvious, fo it requires the more agree- InventMe able drefs to render it delightful; left otherwife it ' feem rather like an hiftory, than an oration: For which reafon, we find, that epic poets, as Homer, 1 Virgil, and others, begin with the middle of their ftory, and afterwards take a proper occafion to intro- j duce what preceded, to diverfify the fubjedt, and i give the greater pleafure and entertainment to their readers. 2. The other method above hinted was, to reduce the difeourfe to certain general heads, without regard¬ ing the order of time. As if any one, in praifing the elder Cato, (hould propofe to do it, by (hewing, that he was a moft prudent fenator, an excellent orator, and moft valiant general; all which commendations are given him by Pliny. In like manner, the charac- ter of a good general may be comprifed under four heads ; (kill in military affairs, courage, authority, | and fuccefs: from all which Cicero commends Pom- pey. And agreeably to this method Suetonius has written the lives of the firft twelve Csefars. But in praifing of perfons, care (hould always be ■ taken, to fay nothing that may feem fi&itious, or out i of charafter, which may call the orator’s judgment j or integrity in qneftion. It was not without caufe, therefore, that Lyfippus the ftatuary, as Plutarch \ tells us, blamed Apelles for painting Alexander the Great with thunder in his hand ; which could never • fuit his charadler as a man, however he might boaft of 1 his divine defeent: for which reafon Lyfippus himfelf made an image of him holding a fpear, as thefign of a warrior. Light and trivial things in commendations are likewife to be avoided, and nothing mentioned ,! but what may carry in it the idea of fomething truly valuable, and which the hearers may be fuppofed to wifh for, and is proper to excite their emulation. j Thefe are the principal heads of praife with relation to men. In difpraife, the heads contrary to thefe are requifite ; which being fufficiently clear from what has been faid, need not particularly be infilled on. II. We proceed therefore to the other part of the divifion, which refpefts things, as diftinguiftied from j perfons. By which we are to underftand all beings inferior to man, whether animate or inanimate ; as likewife the habits and difpofitions of men, either good or bad; when confidered feparately, and apart from , their fubjefls, as arts and fciences, virtues and vices, with whatever elfe may be a proper fubjeft for praife i or difpraife. Some writers, indeed, have, for their own amufement and the diverfion of others, difplayed i their eloquence in a jocofe manner upon fubjefts of this kind. So Lucian has written in praife of a fly, and Syncfiiis an elegant encomium upon baldnefs. { Others, on the contrary, have done the like in a fa- tyrical way. Such is Seneca’s apotheofis or confe- cration of the emperor Claudius; and the Myfopogon or beard-hater, written by Julian the emperor. Not to mention feveral modern authors, who have imitated them in fuch ludicrous compofitions. But as to thefe j things, and all of the like nature, the obfervation of I Antony in Cicero feems very juft : “ That it is not neceffary to reduce every fubjed we difeourfe upon to rules of art.” For many are fo trivial, as not to de- j ferve it; and others fo plain and evidentPof themfelvcs, i" as not to require it. But fince it frequently comes in t O R A r - the way both of orators and hlftorians to defcribe countries, cities, and fadts, we rtiall briefly mention the principal heads of invention proper to illuftrate each of thefe. Countries, then, may be celebrated from the plea- fan tnefs of their fituation, the clemency and whole- fomenefs of the air, and goodnefs of the foil; to which laft may be referred the fprings, rivers, woods, plains, mountains, and minerals. And to all thefe may be added their extent, cities, the number and antiquity of the inhabitants; their policy, laws, cuftoms, wealth, charadler for cultivating the arts both of peace and war ; their princes, and other eminent men they have produced. Thus Pacatus has given us a very elegant defcription of Spain, in his panegyric upon the em¬ peror Theodofius, who was born there. Cities are praifed from much the fame topics, as countries. And here, whatever contributes either to their defence, or ornament, ought particularly to be mentioned ; as the ftrength of the walls and fortifica¬ tions, the beauty and fplecdor of the buildings, whe¬ ther facred or civil, public or private. We have in Herodotus a very fine defcription of Babylon, which was once the ftrongeft, largeft, and moft regular city in the world.' And Cicero has accurately defcribed the city of Syracufe, in the ifland Sicily, in one of his orations againtt Verres. But fads come much oftener under the cognizance of an orator. And thefe receive their commendation from their honour, juftice, or advantage. But in de- fcribing them, all the circumftances Ihould be related in their proper order ; and that in the moft lively and affcdting manner, fuited to their different nature. Livy has reprefented the demolition of Alba by the Roman army, which was fent thither to deftroy it, through the whole courfe of that melancholy fcene, in a ftyle fo moving and pathetic, that one can hardly forbear condoling with the inhabitants, upon reading bis account. But in difcourfes of this kind, whether of praife or difpraife, the orator Ihould (as he ought indeed upon all occafions) well confider where, and to whom, he fpeaks. For the wife men often think very differently both of perfons and things from the common people. And we find that learned and judicious men are fre¬ quently divided in their fentiments, from the feveral ways of thinking to which they have been ac- cuftomed. Befides, different opinions prevail, and gain the afcendant, at different times. While the Romans continued a free nation, love of their country, liberty, and public fpirit, were principles in the higheft efteem among them. And therefore, when Cato killed himfelf, that he might not fall into the hands of Casfar, and furvive the liberty of his country, it was thought an inftance of the greateft heroic virtue; but afterwards, when they had been ac- cuftomed to an arbitrary government, and the fpirit of liberty was now loft, the poet Martial could ven¬ ture to fay, Death to avoid ’tis madnefs fure to die. A prudent orator therefore will be cautious of op- pofing any fettled and prevailing notions of thofe -to whom he addreffes ; unlefs it be neceffary, and then he will do it in the fofteft and moft gentle manner. Vol. VIII. t r ° ttil Chap. III. Of Arguments fuited to Deliberative -nvei'■■■ -• Difcourfes. This kind of difcourfes mull certainly have been 22 very ancient} fince, doubtlefs, from the firft beginning of mens converfing together, they deliberated upon their common intereft, and offered their advice to each other. But neither thofe of the laudatory nor judi¬ cial kind could have been introduced, till mankind were fettled in communities, and found it neceffary to encourage virtue by public rewards, and bring vice under the reftraint of laws. The early pra&ice of fuafory difcourfes appears from facred writ, where we find, that when Mofes was ordered upon an embaffy into Egypt, he would have excufed himfelf for want of eloquence. And Homer reprefents the Greeks at the fiege of Troy, as flocking like a fvvarm of bees to hear their generals harangue them. Nor is this part of oratory lefs confpicuous for its ufefulnefs to man¬ kind, than its antiquity; being highly beneficial either in councils, camps, or any focieties of men. How many inftances have we upon record, where the fury of an enraged multitude has been checked and appealed by the prudent and artful perfuafion of fome particular perfon ? The ftory of Agrippa Menenius, when the commons of Rome withdrew from the fena- tors, and retired out of the city, is too well known, to need reciting. And how often have armies been animated and fired to the moft dangerous exploits, or recalled to their duty, when ready to mutiny, by a moving fpeech of their general? many inftances o£ which we find in hiftory. All deliberation refpefts fomething future, for it is in vain to confult about what is already paft. The fubjedl-matter of it is, either things public or private, facred or civil; indeed all the valuable concerns of mankind, both prefent and future, come under its regard. And the end propofed by this kind of dif¬ courfes is chiefly profit or intereft. But fince nothing is truly profitable, but what is in fome refped good ; and every thing, which is good in itfelf, may not in all circumftances be for our advantage ; properly fpeaking, what is both good and profitable, or bene¬ ficial good, is the end here defigned. And therefore, as it fometimes happens, that what appears profitable, may feem to interfere with that which is ftri&ly juft and honourable ; in fuch cates it is certainly moft advifeable to determine on the fafer fide of honour and juftice, notwithftanding fome plaufible things may be offered to the contrary. But where the difpute Ires apparently between what is truly honed, and fome external advantage propofed in oppofition to it, all good men cannot but agree in favour of honefty. Such was thecafe of Regulus, who, being taken prifoner by the Carthaginians, was permitted to go to Rome upon giving his oath, that unlefs he could perfuade the fenate to fet at liberty fome young Carthaginian noblemen, then prifoners at Rome, in exchange for him, he fhould return again to Carthage. But Re¬ gulus, when he came to Rome, was fo far from en¬ deavouring to prevail with the fenate to comply with the defirc of the Carthaginians, that he ufed all his intereft to diffuade them from hearkening to the pro- pofal. Nor could the moft earneft intreaties of his 31 Z neareft < 5656 Invention. ORATORY. Part IJ nearell relations and friends, nor any arguments they were able to offer, engage him to continue at Rome, and not return again to Carthage. He had then plainly in his view, on the one fide, eafe, fecurity, affluence, honours, and the enjoyment of his friends; and on the other, certain death, attended with cruel torments. However, thinking the former not con- fiftent with truth and juftice, he chofe the latter. And he certainly afled as become an honed and brave man, in choofing death, rather than to violate his oath. Though whether he did prudently in per- fuading the fenate not to make the exchange, or they in complying with him, we fhall leave others to deter¬ mine. Now, when it proves to be a matter of debate, whether a thing upon the whole be really beneficial or not ; as here arife two parts, advice and diffuafion, they will each require proper heads of argument. But as they are contrary to each other, he who is ac¬ quainted with one, cannot well be ignorant of the other. We fhall therefore chiefly mention thofe pro¬ per for advice, from whence fuch as are fuited to difluade will eafily be perceived. Now the principal heads of this kind are thefe following, which are taken from the nature and properties of the thing itfelf under confideration. 1. Pleafnre often affords a very cogent argument in difcourfes of this nature. Every one knows what an influence this has upon the generality of mankind. Though, as Quintilian remarks, pleafure ought not of itfeif to be propofed as a fit motive for aftion in ferious difcourfes, but when it is defigned to recom¬ mend fomething ufeful, which is the cafe here.- So, would any one advife another to the purfuit of polite literature, Cicero has furnifhed him with a very ftrong inducement to it from the pleafure which attends that Andy, when he fays: “ If pleafure only was propofed by thefe ftudies, you would think them an entertain¬ ment becoming a man of fenfe and a gentleman. For other purfuits neither agree with all times, all ages, nor all places ; but thefe ftudies improve youth, de¬ light old age, adorn profperity, afford a refuge and comfort in adverfity, divert us at home, are no hin¬ drance abroad, fleep, travel, and retire with us into the country.” 2. Profit, or advantage. This has no lefs influence upon many perfons than the former ; and when it re- fpeiSs things truly valuable, it is a very juft and laudable motive. Thus Cicero, when he fends his Boohs of of¬ fices to his fon, which he wrote in Latin for his ufe, advifes him to make the beft advantage both of his tutor’s inftru&ions, and the converfation at Athens, where he then was; but withal to perufe his philofo- pbical treatifes, which would be doubly ufeful to him, not only upon account of the fubje&s, but likewife of the language, as they would enable him to exprefs himfelf upon thofe arguments in Latin, which before had only been treated of in Greek. 3. Honour; than which no argument will fooner prevail with generous minds, or infpire them with greater ardour. Virgil has very beautifully defcribed He&or’s ghoft appearing to JEneas the night Troy was taken, and advifing him to depart from this mo¬ tive of honour: O gofldefs-born, efcape Jiy timely flight The flames, and horrors of this fatal night. The foes already have poflefs’d the wall, Troy nods from high, and totters to her fall. Enough is paid to Priam’s royal name ; More than enough to duty, and to fame. If by a mortal hand my father’s throne Cou’d be defended, ’twas by mine alone. The argument here made ufe of to perfuade iEneas to leave Troy immediately, is, that he had done all that could be expe&ed from him, either as a good fubjedl or brave foldier, both for his king and country; which were fufficient to fecure his honour: and now there was nothing more to be expefted from him, when the city was falling, and impoffible to be faved ; which could it have been preferved by human power, he himfelf had done it. But although a thing confidered in itfelf appear be¬ neficial if it could be attained, yet the expediency of undertaking it may ftill be queftionable ; in which cafe the following heads taken from the circumftances which attend it, will afford proper arguments to en¬ gage in it. (1.) The pojfibility of fucceeding may fometimesbe argued, as one motive to this end. So Hannibal en¬ deavoured to convince king Antiochus, that it was poflible for him to conquer the Romans, if he made Italy the feat of the war; by obferving to him, not only that the Gauls had formerly deftroyed their city ; but that he had himfelf defeated them, in every battle he fought with them in that country. (2.) But an argument founded upon probability W\W be much more likely to prevail. For in many affairs of human life, men are determined either to profecute them or not, as the profpeft of fuccefs appears more or lefs probable. Hence Cicero, after the fatal battle at Pharfalia, diffuades thofe of Pompey’s party, with whom he was engaged, from continuing the war any longer againft Caefar ; becaufe it was highly impro¬ bable, after fuch a defeat, by which their main ftrength was broken, that they fliould be able to Hand their ground, or meet with better fuccefs than they bad be¬ fore. (3.) But further, fince probability is not a motive ftrong enough with many perfons to engage in the profecution of a thing which is attended with confi- derable difficulties, it is often neceffary to reprefent the facility of doing it, as a further reafon to induce them to it. And therefore Cicero makes ufe of this argument to encourage the Roman citizens in oppo- fing Mark Anthony (who upon the death of Csefar had affumed an arbitrary power), by reprefenting to them, that his circumftances were then defperate, and that he might eafily be vanquifhed. (4.) Again, if the thing advifed can be (hewn to be in any refpeft neceffary, this will render the mo¬ tive ftill much ftronger for undertaking it. And there¬ fore Cicero joins this argument with the former, to prevail with the Roman citizens to oppofe Anthony, by telling them, that “ The confideration before them was, not in what circumftances they fhould live ; but whether they fliould live at all, or die with ignominy and difgrace.” This way of reafoning will fometimes prevail when all others prove ineffeflual. For feme perfons are not to be moved, til! things are brought to an extremity, and they find themfelves reduced to the utmoit danger. (5.) To thefe heads may be added the confidera¬ tion Part I. ORATORY. 5657 Hmation. tion of the event, which in fome cafes carries great “ weight with it. As when we advife to the doing of a thing from this motive, That whether it fucceed or not, it will yet be of fervice to undertake it. So after the great vi&ory gained by Themiftocles over the ” Perfian fleet at the {traits of Salamis, Mardoniusad- vifed Xerxes to return into Afia himfelf, left the re¬ port of his defeat fhould occafion an infurreftion in his |jj abfence : but to leave behind him an army of 300,000 men under his command ; with which, if he fhould conquer Greece, the chief glory of the conqueft would redound to Xerxes; but if the defign mifcarried, the difgrace would fall upon his generals. Thefe are the principal heads which furnifh the orator with proper arguments in giving advice. Cicero, in his oration for the Manilian law, where he endea¬ vours to perfuade the Roman people to choofe Pom- pey for their general in the Mithridatic war, reafons from three of thefe topics, into which he divides his whole difcoprfe; namely, the neceffity of the war, the greatnefs of it, and the choice of a proper general. Under the firft of thefe he fhews, that the war was ne- ceifary from four- confiderations ; the honour of the Roman ftate, the fafety of their allies, their own reve¬ nues, and the fortunes of many of their fellow citi¬ zens, which were all highly concerned in it, and call¬ ed upon them to put a flop to the growing power of king Mithridates, by which they were all greatly en¬ dangered. So that this argument is taken from the head of necejjity. The fecond, in which he treats of the greatnefs of the war, is founded upon the topic of fojftbility. For though he fhews the power of Mithri¬ dates tobe very great, yet not fo formidable, but that he might be fubdued ; as was evident from the many advantages Lucullus had gained over him and his af- fociates. In the third head, he endeavours to prevail with them tointruftthe managment of the war in the hands of Pompey, whom he defcribes as a confum- mate general, for his fkill in military affairs, courage, authority, and fuccefs; in all which qualities he re- prefents him as fuperior to any other of their gene¬ rals whom they could at that time make choice of. The defign of all which was, to perfuade them, that they had very good reafon to hope for fuccefs, and a happy event of the war, under his conduft. So that that the whole force of his reafoning under this head is drawn from probability. Thefe are the three gene¬ ral topics which make up that fine difcourfe. Each of which is indeed fupported by divers other arguments and confiderations, which will be obvious in perufing the oration itfelf, and therefore need not be here enu¬ merated. On the contrary, in another oration he en¬ deavours to diffuade the fenate from confenting to a peace with Mark Anthony, becaufe it was bafe, dan¬ gerous, and imprafticable. But no fmall fkill and addrefs are required in giving advice. For fince the tempers and fentiments of man¬ kind, as well as their circumftances, are very different and various ; it is often neceffary to accommodate the difcourfe to their inclinations and opinions of things. And therefore the weightieft arguments are not al¬ ways the moft proper, and fitteft to be ufed on alloc- cafions. Cicero, who was an admirable mafterof this art, and knew perfeftly well how to fuit what he faid to the tafte- and relifti of his hearers, in treating upon 3 this fubjeft, diftinguifhes mankind into two forts; the Invention, ignorant and unpolifhed, who always prefer profit to- honour ; and fuch as are more civilized and polite, who prefer honour and reputation to all other things. Wherefore they are to be moved by thefe different views: Praife, glory, and virtue, influence the one; while the other is only to be engaged by a profpeft of gain and pleafure. Befides, it is plain, that the gene¬ rality are much more inclined to avoid evils than to purfue what is good ; and to keep clear of fcandal and difgrace, than to praftife what is truly generous and noble. Perfons likewife of a different age aft from different principles; young men for the moft part view things in another light, from thofe who are older, and have had more experience, and confequently are not to be influenced by the fame motives. Chap. IV. Of Arguments fuited to Judicial Difcourjes. In judicial controverfies there are two parties; the 23 plaintiff or profecutor, and the defendant or perfon charged. The fubjeft of them is always fomething paft. And the end propofed by them Cicero calls equi¬ ty, or right and equity; the former of which arifes from the laws of the country, and the latter from rea¬ fon and the nature of things. For at Rome the prae¬ tors had a court of equity, and were empowered, in many cafes relating to property, to relax the rigour of the written laws. But as this fubjeft is very copious, and caufes may arife from a great variety of things, writers have reduced them to three heads, which they call Jlates, to fome one of which all judicial proceed¬ ings may be referred ; namely, ’whether a thing is, cwhat it is, or hoifpo!ition this is yet frefli.” And again: “ But I have infifted too long upon trifles, let us come to tilings of greater moment.” And at other times, for greater brevity, the tranfition is imperfefl, and mention made only of the following head, without any intimation of what has been faid already. As in Cicero’s defence of Muraena, where he fays : “ I muft now proceed to the third part of my oration concerning the charge of bribery.” And foon after : “ I come now to Cato, who is the fupport and ftrength of this charge.” III. The third and la!t head is, Amplification. Now by amplification is meant, not barely a method of eu- larging upon a thing, but fo to reprefent it in the fulleft and moil comprehenfive view, as that it may in the livelieft manner ftrike the mind, and influence the paffions. Cicero fpeaking of this, cz\\s\t the greatejl commendation of eloquence; and obferves, “ that it confifts not only in magnifying and heightening a thing, but likewife in extenuating and lefiening it.” But though it coniifts of thefe two parts, and may be ap¬ plied either way; yet to amplify, is not to fetthings in a falfe light, but to paint them in their juft pro- .portion and proper colours, fuitable to their nature and qualities. Rhetoricians have obferved feveral ways of doing this. One is to afcend from a particular thing to a gene¬ ral. Thus Cicero, in his defence of Archias, having commended him as an excellent poet, and likewife ob¬ ferved, that all the liberal arts have a connexion with each other, and a mutual relation between them, in order to raife a juft efteem of him in the minds of his hearers, takes occafion to fay many things in praife of polite literature in general, and the great advantages that may be received from it. “ You will aflt me,” fays he, “ why we are fo delighted with this man ? Becaufe he fupplies us with thofe things, which both refrefh our minds after the noife of the forum, and delight our ears when wearied with contention. Do you think we could either be furnifhed with matter for fuch a variety of fubjeCls, if we did not cultivate our minds with learning ; or bear fuch a conftant fatigue, without affording them that refrefhment ? I own I have always purfued thefe ftudies; let thofe be afhamed, who have fo given up themfelves to learning, as neither to be able to convert it to any common benefit, nor difcover it in public. But why fhould it fhame me, who have fo lived for many years, that no ad¬ vantage or cafe has ever diverted me, no pleafure allured me, nor fleep retarded me, from this purfuit. Who then can blame me, or who can juftly be dif- pleafed with me, if I have employed that time in re¬ viewing thefe ftudies, which has been fpent by others in managing their affairs, in the celebration of fefti- vals, or other diverfions, in refrefhments of mind and body, in unfeafonable banquets, in dice, or tennis ? And this ought the rather to be allowed me, becaufe my ability as an orator has been improved by thofe purfuits, which, fuch as it is, was never want¬ ing to aflift my friends. And if it be efteemed but fmall, yet I am fenfible from what fpring I muft draw thofe things, which are of the greateft impor¬ tance.” With more to the fame purpofe; from which he draws this inference: “ Shall I not therefore love this man ? (hall I not admire him ? fhall I not by all means defend hitja ?” ' O It Y. 5681 A contrary method to the former is, to defcend DifpofitioM from a general to a particular. As if any one, while fpeaking in commendation of eloquence, (hould illu- ftrate what he fays from the example of Cicero, and (hew the gieat fervices he did his country, and the honours he gained to himfelf, by his admirable Ikill in oratory. Our common way of judging of the nature of things is from what we obferve in particular in- ftances, by which we form general notions concerning them. When therefore we confider the charadter of Cicero, and the figure he made in the world, it leads us to conclude, there muft be fomething very admi¬ rable in that art by which he became fo celebrated. And this method he has taken himfelf in his oration for the Manilian law, where having firft intimated the fcarcity of good generals at that time among the Ro¬ mans, he then defcribes the virtues of a complete com¬ mander as a proof of it, and {hews how many and great qualifications are neceffary to form fuch a cha- radler, as courage, prudence, experience, and fuccefs; all which he afterwards applies to Pompey. A third method is by an enumeration of parts. So when Cicero, upon the defeat of Mark Antony before Mutina, propofed that a funeral monument {hould be eredted in honour of the foldiers who were killed in that battle, as a comfort to their furviving relations; he does it in this way, to give it the greater weight: “ Since (fays he) the tribute of glory is paid to the beft and moft valiant citizens by the honour of a mo¬ nument, let us thus comfort their relations, who will receive the greateft confolation in this manner: their parents, who produced fuch brave defenders of the ftate; their children, who will enjoy thefe domeftic examples of fortitude ; their wives, for the lofs of fuch hufbands, whom it will be more fitting to extol than lament ; their brethren, who will hope to re¬ ferable them no lefs in their virtues, than their afpedt. And I with we may be able to remove the grief of all thefe by our refolutions.” Such reprefentations greatly enlarge the image of a thing, and afford the mind a much clearer view of it than if it were contradted into one fingle propofition. Again, another method not much unlike the former is, when any thing is illuftrated from a variety of caufes. Thus Cicero juftifies his behaviour in retiring, and not oppofing his enemies, when they fpirited up the mob in order to banilh him, from the following reafons, which at that time determined him to fuch a condudl: “ When (fays he) unlefs I was given up, fo many armed fleets feemed ready to attack this fingle {hip of the ftate, toffed with the tempefts of feditions and difcords, and the fenate was now removed from the helm ; when banifliment, murder, and outrage, were threatened; when fome, from an apprehenfion of their own danger, would not defend me; others were incited by an inveterate hatred to all good men, others thought I Hood in their way, others took this oppor¬ tunity to exprefs their refentment, others envied the peace and tranquillity of the ftate; and upon all thefe accounts I was particularly ftruck at: {hould I have chofen rather to oppofe them, (I will not fay to my own certain deftrudtion, but to the greateft danger both of you and your children), than alone to fubmit to and undergo what threatened us all in common?” Such a number of reafons brought together, muft fet a 32 C z thing 5682 ORA' Difpofition thing in a very ftrong and clear light. The like may be faid of a number and variety of effe&s. Thus Cicero defcribes the force and excel¬ lence of oratory from its great and furprifing effects, when he fays, “ Nothing feems to me more excellent, than by difcourfe to draw the attention of a whole aflembly, delight them, and fway their inclinations different ways at pleafure. This, in every free ftate, and efpecially in times of peace and tranquillity, has been always in the higheft efteem and reputation. For what is either fo admirable, as for one only, or a very few, out of a vaft multitude, to be able to do that which all have a natural power of doing? or fo delightful to hear, as a judicious and folid difcourfe in florid and polite language? or fo powerful and grand, as to influence the populace, the judges, the lenate, by the charms of eloquence? Nay, what is fo noble, fo generous, fo munificent, as to afford aid to fupplicants, to fupport the afflifted, give fafety, deliver from dangers, and preferve from exile? Or what is fo neceffary as to be always furnifhed with arms to guard yourfelf, affertyour right, or repel injuries? And, not to confine our thoughts wholly to the courts of juftice or the fenate, what is there in the arts of peace more agreeable and entertaining than good language and a fine way of fpeaking? For it is this efpecially where¬ in we excel other animals, that we can difcourfe toge¬ ther, and convey our thoughts to each other by words. Who therefore would not efteem, and in a particular manner endeavour to furpafs others in that wherein mankind principally excels brute hearts? But to pro¬ ceed to itschief advantages: What elfe would have drawn men into focieties, or taken them off from a wild and favage life, and foften them into a polite and civilized behaviour; or, when fettled in communities, have re- llrained them by laws?” Who but, after fuch a de- fcription, mu ft conceive the ftrongeft paflion for an art attended with fo many great and good effeds? A thing may likewife be illuftrated by its oppofite. So the blefiings and advantages of peace may be re¬ commended from the miferies and calamities of war; and thus Cicero endeavours to throw contempt upon Catiline and his party, by comparing them with the contrary fide: “ But if, omitting all thefc things with which we abound, and they want, the fenate, the knights, the populace, the city, treafury, revenues, all Italy, the provinces, and foreign nations; if, I fay, r O R Y. PartlH omitting thefe things, we compare the canfes them-Dhpolinik felves in which each fide is engaged, we may learn F from thence how defpicable they are.—For on this |' fide modefty is engaged, on that impudence; on this chaftity, on that lewdnefs; on this integrity, on that fraud; on this piety, on that profanenefs; on this 1 conftancy, on that fury; on this honour, on that bafe- nefs; on this moderation, on that unbridled pafiion: j In a word, equity, temperance, fortitude, prudence, I and all virtues, contend with injuftice, luxury, cow¬ ardice, rafttnefs, and all vices; plenty with want; rea- fon with folly; fobriety with madnefs; and, laftly, | good hope with defpair. In fuch a conteft,’ did men defert us, would not heaven ordain that fo many and fo great vices ftiould be defeated by thefe moft excel¬ lent virtues?” Gradation is ansther beautiful way of doing this. So when Cicero would aggravate the cruelty and bar¬ barity of Verres for crucifying a Roman citizen, which was a fort of punifhment only inflifted upon flaves, he choofes this way of doing it. “ It is a crime (fays he) to bind a Roman citizen, wickednefs to whip him, and a fort of parricide to kill him; what then muft I call it to crucify him? No name can fufficiently ex- prefs fuch a villany.” And the images of things may be thus heightened, either by afcending, as in this in- ftance; or defcending, as in that which follows, re¬ lating to the fame adtion of Verres: “ Was I not to complain of or bewail thefe things to Roman citizens, nor the friends of our ftate, nor thofe who had heard of the Roman name; nay, if not to men, but beafts; or, to go yet further, if in the moft defert wildernefs to (tones and rocks ; even all mute and inanimate creatures would be moved by fo great and heinous cruelty.” And, to name no more, fadts may be amplified from their circumftances ; as time, place,, manner, event, and the like. But inftances of this would carry us too far; and therefore we (hall only add, that, as the defign of amplification is not barely to prove or evince the truth pf things, but alfo to adorn and illuftrate them, it requires a florid and beautiful ftyle, confiding of ftrong and emphatical words, flowing periods, har¬ monious numbers, lively tropes, and bright figures. But the confideratioti of thefe things come under the third part of oratory, upon which we are now to enter. Part III. Of E ELOCUTION dire&s us to fuit both the words and expreffions of a difcourfe to the nature of the fubjedf, or to fpeak with propriety and decency. This faculty is in one word called eloquence; and thofe per- fons who are pofleffed of it are therefore ftyled elo~ quent. Elocution is twofold ; general, and particular. The former treats of the feveral properties and ornaments of language in common ; the latter confiders them as they are made ufe of to form different forts of ftyle. I. GENERAL ELOCUTION. This, according to rhetoricians, confifts of three LOCUTION. parts; Elegance, Compofition, and Dignity. A difcourfe which has all thefe properties fuitably adjufted, muft, with refpedt to the language, be perfedt in its kind, and delightful to the hearers. Chap. I. Of Elegance. Elegance confifts in two things; Purity, and/Vr- fpicuity: And both thefe, as well with refpedl to fingle words, as their conftrudtion in fentences. Thefe pro¬ perties in language give it the name of elegant, for a like reafon that we call other things fo which are clean and neat in their kind. But in the common ufe of our tongue, we are apt to confound elegance with elo¬ quence i and fay, a difcourfe ij elegant, when we mean Part III. locution, by the expreffion, that it has all the properties of fine " language. § I. Purity. 41 By this we are to underftand the choice of fuch words and phrafes as are fuited and agreeable to the ufeof the language in which we fpeak: And fo gram¬ marians reduce the faults they oppofe to it to two forts, which they call barbarifm and folccifm; the former of which refpedts Angle words, and the latter their conftru&ion. But we lhall confider them jointly, and in a manner different from grammarians; for with them all words are efteemed pure, which are once adopted into a language, and authorifed by ufe. And as to phrafes, or forms of expreffion, they allow them all the fame claim, which are agreeable to the analogy of the tongue. But in oratory, neither all words nor all expreffions are fo called, which occur in language; but fuch only as come recommended by the authority of thofe who fpeak or write with accuracy and politenefs. Indeed it is a common faying, that •we Jhould think •with the learned, and fpeak ivith the vulgar. But the meaning of that expreflion is no ’ more than that we fhould fpeak agreeably to the com¬ mon ufage of the tongue, that every one may under¬ ftand us; and not choofe fuch words or expreffions as are either difficult to be underftood, or may carry in them an appearance of affe&ation and Angularity. But in order to fet this matter in a clearer light, we {hall here recount the principal things which vitiate the purity of language. And firff, it often happens, that fuch words and forms of fpeaking as were introduced by the learned, are afterwards dropped by them as mean and fordid, from a feeming baienefs coritrafted by vulgar ufe. For polite and elegant fpcakers diftinguiffi themfelves by their difcourfe, as perfons of figure do by their garb; one being the drefs of the mind, as the other is of the body. And hence it comes to pafs, that both have their different fafhions, which are often changed; and as the vulgar affefl to imitate thofe above them in both, this frequently occafions an alte¬ ration when either becomes too trite and common. But beiide thefe fordid words and expreffions, which are rendered fo by the ufe of the vulgar ; there is another fort firft introduced by them, which is carefully to be avoided by all thofe who are defirous to fpeak well. For the vulgar have their peculiar words and phrafes, fuited to their circumftances, and taken from fuch things as ufually occur in their way of life. Thus in the old comedians, many things are fpoken by fer- vants, agreeable to their eharaSer, which would be very unbecoming from the mouth of a gentleman. And we cannot but daily obferve the like inftanccs among ourfekes. Again, this is common to language with all other human produftions, that it is in its own nature liable to a conftant change and alteration. For, as Horace has juftly obferved, All human works (hall wafte, Then how can feeble words pretend to laft? Nothing could ever pleafe all perfons, or at lead for any length of time. And there is nothing from which this can lefs be expefted than language. For as the thoughts of men are exceedingly various, and words 5683 are the figns of their thoughts; they will be eondant- Elocnt on. ly inventing new figns to exprefs them by, in order to convey their ideas with more clearnefs, or greater beauty. If we look into the different ages of the La¬ tin writers, what great alterations and changes do we find in their language ? How few now underftand the remaining fragments of the twelve tables ? Nay, how many words do we meet with even in Plautus, the meaning of which has not yet been fixed with certain¬ ty by the fkill of the bell critics ? And if we confidtr our own language, it will appear to have been in a manner entirely changed from what it was a few ages fince. To mention no others, our celebrated Chaucer is to moft perfons nowalmoft unintelligible, and wants an expofitor. And even fince our own memory, we cannot but have obferved, that many words and ex¬ preffions, which a few years ago were in common ufe, are now in a manner laid afide and antiquated ; and that others have conftantly fucceeded, and daily do fuc- ceed, in their room. So true is that obfervation of the fame poet: Some words that have or elfe will fee! decay, Shall be reftor’d, and come again in play; And words now fam’d, (hall not be fancied long. They (ball not pleafe the ear, nor move the tongue : As ufe (hall thefe approve, and thofe condemn; Ufe, the foie rule of fpeech, and judge fuprenie. We muff therefore no lefs abftain from antiquated or obfolete words and phrafes, than from fordid ones. Though all old words are not to be thought antiqua¬ ted. By the former we mean fuch as, though of an ancient Handing, are not yet entirely difufed, nor their fignification loft. And from the ufe of thefe we ate not to be wholly debarred, efpecially when they appear more fignificant than any others we can fix upon. But as to phrafes or expreffions, greater caution feems ftill neceffary ; and fuch as are old, fhould doubtlefs, if at all, be ufed more fparingly. The Latin tongue was brought to its greateft perfedion in the reign of Auguftus, or fomewhat fooner ; and he himfelf ftu- died it very carefully. For, as Suetonius tells ins, “ He applied himfelf to eloquence, and the ftudy of the liberal arts, from his childhood, with great dili¬ gence and labour. He chofe a manner of fpeaking which was fmooth and elegant: he avoided the ill fa¬ vour, as he ufed to call it, of antiquated words ; and he was wont to blame Tiberius for his affedation of them.” In our own language, fuch words are to be efteemed antiquated, which the moft polite perfons have dropped, both in their difcourfe and writings ; whofe example we ftiould follow, unlefs we would be thought to converfe rather with the dead than the li¬ ving. But further: As on the one hand we muft avoid ob¬ folete words and phrafes; fo on the other, we fhould refrain from new ones, or fuch whofe ufe has not been yet been fufficiently eftablifhed, at leaft among thofe of the beft tafte. Words may be confidered as new in two refpeds; either when they are firft brought in¬ to a language, or when they are ufed in a new fenfe. As the former of thefe may fometimes leave us in the dark by not being underftood, fo the latter are moft apt to miflead us; for when we hear a word that has been familiar to us, we are prefently led to fix that idea to it with which it has ufually been attended. And ORATORY. I 5684 ORATORY* Part III.I Elocution. And therefore, in both cafes, fome previous intima- fenfe. And tropes fuch words as are applied to E!ocution|iji] tion may be neceffary.

And in our which it may be capable of being brought to a ftan- dard. But befides thofe things already mentioned, any mi- ftake in the fenfe of words, or their conftrudlion, is op- language, it is well known, that the word knave an¬ ciently fignified a fervant. The reafon of the change feems to be much the fame, as in that of the Latin word latro; which firft fignified a foldier, But after- pofed to purity. For to fpeak purely, is to fpeak wards a robber. Befides, in all languages it has fre^ corre&ly. And fuch is the natnre of thefe faults in quently happened, that many words have gradually elocution, that they are often not fo eafy to be obfer- varied from their firft fenfe to others fomewhat diffe- ved by hearing as by reading. Whence it is, that rent ; which may, notwithftanding, all of them, when many perfons are thought to fpeak better than they rightly applied, be looked upon as proper. Nay, in write ; for while they are fpeaking, many flips and in- procefs of time, it is often difficult to fay which is the accuracies efcape difregarded, which in reading would original, or moft proper fenfe. Again, fometimes prefently appear. And this is more efpecially the cafe two or more words may appear to have the fame fig- ofperfons unacquainted with arts and literature; who, nification with each other, and may therefore be ufed by the affiftance of a lively fancy and flow of words, indifferently ; unlefs the beauty of the period, or fome often fpeak with great eafe and freedom, and by that other particular reafon, determine to the choice of means pleafe the ear ; when, at the fame time, what one rather than another. Of this kind are the words they fay, would not fo well bear reading. enfis zndgladius in the Latin tongue; and in oms, pity We fhall only add, that a diftindh’on ought likewife cornpafiion. And there are other words of fo near to be made between a poetic didtion, and that of an affinity to each other, or at lead appear fo from profe writers. For poets in all languages have a fort vulgar ufe, that they are commonly thought to be fy- of peculiar dialed!, and take greater liberties, not only nonymdus. Such are the words mercy and pity; tho* in their figures, but alfo in their choice and difpofition mercy in its ftridl fenfe is exercifed towards an offen- of words; fo that what is a beauty in them would of- der, and pity refpedts one in diftrefs. As this pecu- ten appear unnatural and affedted in profe. liar force and difiindtion of words is carefully to be r n/r of.. attended to, fo it may be known feveral ways. Thus y - J erjpicut y. tj)e pr0per fignification of fubftantives may be feen Perspicuity, as well as purity, confifts partly in by their application to other fubftantives.

Another way to lay down fome few obfervations, by which the di- of diftinguifliing the propriety of words, is by their ftma notions of words and their peculiar force may ufe in gradations. As if one fhould fay, Hatreds, more eafily be perceived. All words may be divided grudges, quarrels, tumults, feditions, wars, fpring into proper words and tropes. Thofe are called proper from unbridled pafiions. The proper fenfe of words words, which are exprdfed in their proper and ufual may likewife be known by obferving to what other words Partin. O R A 1 jjlocution. words they are either oppofed, or ufed as equivalent. ~t—— in that paflage of Cicero, where he fays, “ I can¬ not perceive why you fhould be angry with me: If it be becaufe I defend him whom you accufe, why may not I be difpleafed with you for accufing him whom I defend ? You fay, I accufe my enemy ; and I fay, I defend my friend.” Here the words accufe and defend, friend and enemy, are oppofed ; and to be angry and difpleafed, are ufed as terms equivalent. Lattly, the | derivation of words, contributes very much to deter¬ mine their true meaning. Thus becaufe the word mannen comes from the word man, it may properly be applied either to that, or any other put for it. And therefore we fay, • the manners of men, and the manners of the age; becaufe the word age is there ufed for the men of the age. But if we apply the word manners to any other animal, it is a trope. By thefe, and fuch like obfervations, we may perceive the pro¬ per fenfe and peculiar force of words, either by their connection with other words, diftinftion from them, oppofition to them, equivalency with them, or deri¬ vation. And by thus fixing their true and genuine fig- nification we fhall eafily fee when they become tropes. But though words, when taken in their proper figni- eation, generally convey the plained and cleared fenfe} yet fome are more forcible, fonorous, or beautiful than others. And by thefe confiderations we mud often be determined in our choice of them. So whe¬ ther we fay, he got, or he obtained, the vittory, the fenfe is the fame; but the latter is more full and fonorous. In Latin, timeo fignifies / fear; pertimeo is more full and fignificant, and pertimefco more fonorous than ei¬ ther of the former. The Latin and Greek languages have much the advantage of ours in this refped, by reafon of their compofnions ; by the help of which they can often exprefs that in one word, for which we are obliged to put two words, and fometimes more. So pertimeo cannot be fully exprefled in our language by one word ; but we are forced to join one or two particles to the verb, to convey its jud idea, and fay, I greatly, or very much fear: and yet even then, we fcarce feem to reach its full force. As to tropes, tho* generally fpeaking they are not' to be chofen where plainnefs and perfpicuity of expreflion is only defign- ed, and proper words may be found ; yet through the penury of all languages, the ufe’of them is often made neceflary. And fome of them, efpecially meta¬ phors, which are taken from the fimilitude of things, may, when cudom has rendered them familiar, be confidered as proper words, and ufed in their dead. Thus, whether we fay, I fee your meaning, or, 1 un- derftand your meaning, the fenfe is equally clear, tho’ the latter expreflion is proper, and the former meta¬ phorical, by which the aftion of feeing is transferred from the eyes to the mind. II. Ibux. perfpicuity arifes not only from a choice of ftngle •vjords, but likewife from the confruftion of them in fentences. For the meaning of all the . words in a fentence, confidered by themfelves, may be R!> very plain and evident; and yet, by reafon of a difor- derly placing them, or confufion of the parts, the fenfe of the whole may be very dark and obfeure. Now it is certain, that the mod natural order is the plained ; that is, when both the words and parts of a fentence are fo difpofed, as bed agrees with their mu- o It Y. 5685 tual relation and dependence upon each other. And Elocution, where this is changed, as is ufually done, efpecially in the ancient languages, for the greater beauty and harmony of the periods; yet due regard is had by the bed writers to the evidence and perfpicuity of the ex- preffion. But to fet this fubjedt in a clearer light, on which the perfe&ion of language fo much depends, we fhall mention fome few things which chiefly occafion obfeu- rity; and this either with refpedi to Angle words, or their conflruftion. And firfl, all ambiguity of expreflion is one caufe of obfeurity. This fometimes arifes from the different fenfes in which a word is capable of being taken. So we are told, that upon Cicero’s addrefling himfelf to Oedavius Caefar, when he thought himfelf iu danger from his refentment, and reminding him of the many fervices he had done him, Ociavius replied. He came the laf of his friends. But there was a defigned am¬ biguity in the word laf, as it might either refpedf the time of his coming, or the opinion he had of his friendfhip. And thisufe of ambiguous words we fome¬ times meeet with, not only in poetry, where the turn and wit of an epigram often refts upon it; but like¬ wife in profe, either for pleafantry or ridicule. Thus Cicero calls Sextus Clodius, the light of the fenate; which is a compliment he pays to feveral great men, who had diftinguifhed themfelves by their public fer¬ vices to their country. But Sextus, who had a con¬ trary chara&er, was a relation of P. Clodius, whofe dead body, after he had been killed by Milo, he car¬ ried in a tumultuous manner into the fenate-houfe, and there burnt it with the fenators benches, in order to inflame the populace againft Milo. And it is in allu- fion to that riotous action, that Cicero, ufing this am- guous expreflion, calls him the light of the finale. In fuch inftances, therefore, it is a beauty, and not the fault we are cautioning againft ; as the fame thing may be either good or bad, as it is differently applied. Tho’ even in fuch defigned ambiguities, where one fenfe is aimed at, it ought to be fufficiently plain, otherwife they lofe their intention. And in all ferious difeourfes they’ought carefully to be avoided. But obfeurity more frequently arifes from the ambiguous conftruction of words, which renders it difficult to determine in what fenfe they are to be taken. Quintilian gives us this example of it: “ A certain man ordered in his will, that his heir fhould erett for him a ftatue holding a fpear made of gold.” A queftfon arifes here, of great confequence to the heir from the ambiguity of the ex¬ preflion, whether the words made of gold, to be applied to the fatue or the fpear ; that is, whether it was the defign of the teftator by this appointment, that the whole ftatue, or only the fpear, fhould be made of gold. A fmall note of dillinftion, different¬ ly placed between the parts of this fentence, would clear up the doubt, and determine the fenfe either way. For if one comma be put after the word fatue, and another after fpear, the words made of gold muft be referred to the ftatpe, as if it had been faid, a fatue, made of gold, holding a fpear. But if there be only the fir ft comma placed after fatue, it will limit the words snade of gold to the fpear only ; in the fame fenfe as if it had been faid, A fatue holding a golden fpear. And either of thefe ways of expreffion would 1 5686 O R A 1 Elocution. In this cafe have been preferable, for avoiding theam- ~ biguity, according to the intention of the teftator. The ancient heathen oracles were generally delivered in fuch ambiguous terms. Which, without doubt, were fo contrived on purpofe, that thofe who gave out the anfwers might have room left for an evafion. Again, obfcurity is occafioned either by too fhort and concife a manner of fpeaking, or by fentences too long and prolix ; either of thefe extremes have fome- times this bad confequence. We find an inftance of the former in Pliny the elder, where, fpeaking of hel¬ lebore, he fays, “ They forbid it to be given to aged perfons and children, and lefs to women than men.” The verbis wanting in the latter part of the fentence, and lefs to •women than men: which in fuch cafes being ufually fnpplied from what went before, would here Hand thus ; and they forbid it to be given lefs to •wo¬ men than men. But this is direftly contrary to the fenfe of the writer, whofe meaning is, either that it is ordered to given in a lefs quantity to women than men, or not fo frequently to women as men. And therefore the word order is here to be fupplied, which being of a contrary fignification to forbid, expreffed in the former part of the fentence, occafions the obfcu¬ rity. That long periods are often attended with the fame ill effefl, muft be fo obvious to everyone’s expe¬ rience, that it would be entirely needlefs to produce any examples in order to evince the truth of it. And therefore we (hall only obferve, that the bed way of preventing this feems to be by dividing fuch fentences as exceed a proper length, into two or more ; which may generally be done without much trouble. Another caiife of obfcurity, not inferior to any yet mentioned, is parenthefis, when it is either too long or too frequent. This of Cicero, in his oration for Sylla, is longer than we ufually find in him : “ O im¬ mortal gods! (for I muft attribute to you what is your own ; nor indeed can I claim fo much to my own abi¬ lities, as to have been able of myfelf to go through fo many, fo great, fuch different affairs, with that ex¬ pedition, in that boifterous tempeft of the date), you inflamed my mind with a defire to fave my country.” But where any obfcurity arifes from fuch fentences, they may frequently be remedied by much the fame means as was juft now hinted concerning long and prolix periods; that is, by feparating the parenthefis from the reft of the fentence, and placing it either before or after. So in this fenttnee of Cicero, the parenthefis may (land laft, in the following manner: “ O immor¬ tal gods! you inflamed my mind with a defire to fave my country: for I muft attribute to you what is your own; nor indeed can I claim fo much to my own abi¬ lities, as to have been able of myfelf to go through fo many, fo great, fuch different affairs, with that expe¬ dition, in that boifterous tempeft of theftate.” This order of the fentence is very plain, and lefs involved than the former. Chap. II. Of Compofition. 44. Composition, in the fenfe it is here ufed, gives ^ rules for the ftrufiure of fentences, with the feveral members, w'ords, and fyllables, of which they con- lift, in fuch a manner as may belt contribute to the force, beauty, and evidence of thewhole. Compofition confifts of four parts, which rhctori- O R Y. Partin. clans call period, order, junfture, and number. The Elocutionl firft of thefe treats on the ftruddure of fentences; the fecond, of the parts of fentences, which are words and f members; and the two laft, of the parts of words, which are letters and fyllables. For all articulate founds, and even the moil minute parts of language, come under the cognizance of oratory. § 1. Of Period. In every fentence or propofition, fomething is faid 4^ of fomething. That of which fomething is faid, logi¬ cians call the fubjett; and that which is faid of it, the predicate: but in grammatical terms, the former is a noun fubjlantive of the nominative cafe, and the latter a finite verb. Thefe two parts may of themfelves conftitute a fentence: As when we fay, The fun fhines, or The clock Jlrikes, the words fun and clock are the fubjedt in thefe exprefiions, Jhines andftrikes the predicate. But moft commonly they are accom¬ panied with other words, which in grammatical con-* ftrudtion are faid either to be connedfed with or to depend upon them ; but in a logical confideration they denote fome property or circumftance relating to them. As in the following fentence : A good man loves virtue for itfelf. The fubjedt of this fentence is a good man ; and the predicate, or thing affirmed of him, that he loves virtue for itfelf. But the two prin¬ cipal or neceffary words, on which all the reft depend, are, man and loves. Now a fimple fentence confifts of one fuch noun and verb, with whatever elfe is joined » j to either or both of them. And a compound fen¬ tence contains two or more of them ; and may be di¬ vided into fo many diftindf propofitions, as there are fuch nouns and verbs, either expreffed or underftood. So in the following fentence, Compliance gains friends, but truth procures hatred, there are two members, each of which contains in it an entire propofition. For, Compliance gains friends, is one complete fentence ; and, Truth procures hatred, is another; which are connedted into one compound fentence by the particle but. Moreover, it frequently happens, that com¬ pound fentences are made up of fuch parts or mem¬ bers, fome if not all of which are themfelves com¬ pounded, and contain in them two or more fimple members. Such is that of Salluft : “ Ambition has betrayed many perfons into deceit; to fay one thing, and to mean another ; to found friendfhip and enmity, not upon reafon, but intereft; and to be more careful to appear honeft, than really to be fo.” This fentence confifts of four members; the laft of which three, con- fifting of oppofite parts, are all compounded, as will appear by expreffing them at length in the following manner: Ambition has betrayed many perfons into deceit; [that is, ambition] has betrayed them to fay one thing, it and to mean another; it has betrayed them to found friendfhip and enmity, not upon reafon, but interef; and it has betrayed them to be more careful to appear honejl, than really to be fo. The three laft of thefe members, beginning with the words it betrays, are ail of them compounded, and confift of two oppofite members; which might each of them be expreffed at length in the fame manner, by fupplying the ellipfis. As, Ambition has betrayed many perfons to fay one thing, and it has betrayed them to mean another. And fo of the reft. From this inftance we fee how much is left c Part III. ORA1 3, EU'cutioii. left to be fupplied by the mind In all difcourfe, which J ' if expreffed would both deftroy its harmony and ren¬ der it exceedingly tedious. But ftill regard muft be had to that which is omitted, fo as to render what is faid confident with it; otherwife there can be no pro¬ priety in what is fpoken. Nor can the members of a fentence be didinguifhed and duly ranged in their pro¬ per order, without this. But to proceed: Some fen- tences confift-either wholly, or in part, of fuch mem- ' bers as contain in them two or more compound ones, which may therefore, for diftindion’s fake, be called decompound jnembers. Of this kind is that of Cicero in his defence of Milo : Great is the force of con- fcience, great either way: that thofe perfons are not afraid who have committed no offence ; and thofe who have offended, always think punifhment prefent be¬ fore their eyes.” The latter member of this fentence, which begins with the word that, contains in it two compound members, which reprefent the different ftate of mind between innocent and guilty perfons. And it is in the proper diftin&ion, and feparation of the members in fuch complex fentences, that the art of pointing chiefly confifts. For the principal ufe of a comma is to divide the fimple members, a femicolon the compound ones, a colon fuch as are decompound¬ ed, and a period the whole from the following fen¬ tence. We mention this the rather, to fhew the dif¬ ferent acceptation of thefe terms by grammarians, from that of the ancient writers upon oratory. For thefe latter apply them to the fenfe, and not to any points of diftin&ion. A very ftiort member, whether fimple or compound, with them is a comma, and a longer a colon ; for they have no fuch term as a femi- colon. Befides, they call a very (liort fentence, whether fimple or compound, a comvia ; and one of fomewhat a greater length, a colon. And therefore, if a perfon expreffed himfelf either of thefe ways in any confider- able number of fentences together, he was to fpeak by commas or colons. f two compound mem¬ bers, which here (land in their natural order, but may¬ be thus inverted : He will fee juft reafon to be always on his guard, and not place too much dependence on things fo precarious ; whoever conftders the uncertainty of human affairs, and how often the greateft hopes are fruftrated. In the following fentence one compound member is included in another: Let us not conclude, while dangers are at a diftance, and do not immediate¬ ly approach us, that we are fecure; unlefs we ufe all neceffary precaution to prevent them. Here the natural order would be : While dangers are at a diftance, and do not immediately approach us ; let us not conclude, that we^are fecure, unlefs we ufe all neceffary precaution to prevesit them. But there are fome other confiderations relating to order, which, being taken from the nature of things, equally fuit all languages. So in amplifying, there {hould be a conftant gradation from a lefs to a greater; as when Cicero fays, Ambition creates hatred, Jhy- nefs, difcords, feditions, and wars. On the contrary, in extenuating, we fhould defcend from a greater to a lefs ; as if, fpeaking of the ancient laws of Rome, one Ihould fay, They were fo far from fuffering a Roman citizen to be put to death, that they would not allow him to be whipt, or even to be bound. In conftituting any whole, we put the parts firft ; as, Invention, difpo- Jition, elocution, and pronunciation, make up the art of oratory. But in feparating any whole, the parts fol¬ low ; as, The art of oratory may be divided into thefe four parts; invention, difpoftticn, elocution, and pronun¬ ciation. In every enumeration care mull be taken not to mix the whole with the parts ; but if it be men¬ tioned at all, it mud either be put firft or laft. So it would be wrong to fay, He was a man of the greateft prudence, virtue, juftice, and modefty : for the word virtue here contains in it the other three, and there¬ fore Ihould not be inferted among them. § 3. Of ffuntture and Number. Quintilian, fpeaking of compofition, reprefents a difcourfe as very happy in that refped, when the order, junfture, and number, are all juft and proper. .The firft of thefe, which gives rules for the due pla¬ cing of the words and members of a fentence, has been already explained. We now proceed to the other two, which relate to letters and fyllables; the former treating of their conneftion, and the latter of their quantity. 46 I. As toyW?are. A due attendance is to be given to the nature of the vowels, confcnants, ^and fyl¬ lables in the conne&ion of words, with regard to the found. As to the firft, when a word ends with a vowel, and the next begins either with a different vowel, or the fame repeated, it ufually renders the pronunciation hollow and unpleafant. For, as Quintilian has juftly obferved, “ This makes a chafm in the fentence, and and Hops the courfe of it.” For there mull be fome paufe, in order to pronounce them both, or other- wife the found of one will 'be loft. So, for inftance, in pronouncing thefe words, the other day, uulefs you O It Y. Tart III. flop a little after the word the, the found ofe will not Elocutions be heard; and if it is dropt, it will cccafion rougher found, from the afpiration of th twice re¬ peated fo near together, as th' other day. Therefore to prevent both thefe inconveniences, we ufually fay, t' other day. But the different confonants, which together with the vowels make up thofe fyllables, of¬ ten caufe a confiderable difference in the pronouncia- tion, fo as to fender it more or lefs agreeable. As, if we fay, he overdid it, the words he over have not fo h?r(h a found, as the other; though dill they re¬ quire fome paufe to keep them diftindl. Befides, fome vowels meet more amicably, and admit of a fofter pro¬ nunciation, than others. Thofe which have the weak- eft and fmalleft found, follow bed ; becaufe they oc- cafion the lead alteration of the organ in forming the two founds. Such are e and i; and therefore, without any chafm in the found, or hefitation of the voice, we fay, he is. But where the adljon of the organs is greater, and the found llronger, the pronunciation is more difficult: as when we fay, tho' all. For here is a contrary motion of the lips, which are firft put for¬ ward in founding the 0, and then drawn backward to pronounce the a; and therefore the found is much fofter to fay, tho' every, where their a&ion is lefs. And the like ill effedt commonly happens from the repetition of the fame vowel : as if we fay, go on; ae^you ufually alt thus. There is a confiderable difference between thefe two expreffions, in repeating the found of the vowel, and where either of them is doubled in a fingle word. For then the famedbund only is protra&ed by one continued motion of the organ; as in the words good, and deem. But here the found is repeated again by a new aftion of the organ; which, if precipitated, obfeures the found of one of the vowels ; and, if too much retarded, makes a chafm in the pronunciation ; either of which is unpleafant to the ear. But as the coalition of two vowels occafions an hollow and obfeure found, fo the the meeting of fome confonants renders it very harfti and rough. Thus the words king Xerxes, and public good, when fo placed, have not only a roughnefs, but likewife a difficulty in their pronunciation, from the country adftion of the lips ; which in the former are firft drawn back and then forward, but in the latter the contrary way, and in both of them with fome eonfiderable force. But this may very eafily be avoided, by faying, with a little alteration in the words, Xerxes the king, and the the good of the public. So likewife the words ill company, have a fofter found, than bad compamy, for the fame reafon. To multiply inftances of this kind feems un- neceffary, which fo frequently occur in all difcourfe. The repetition of the fame fyllable, at the end and beginning of words, is the laft thing to be confidered. And a little obfervation will convince us, that where this happens, it generally renders the found either confufed, or unpleafant. Cicero was often rallied oa account of this verfe : 0 fortunatam natam me confule-Romam. Every one will eafily perceive a difagreeable found in the following expreffion : “ A man many times does that unadvifedly, of which he afterwards repents.” The chime of the words man many both feems affec ted, and difpleafes the ear. But this will foon be re 1 medied, if we feparate thofe two word, and fay, “ A man PartUI. ORATORY. 569 r ^locution, man does that many times unadvifedly.’, word admiralky where none but the firft fyllabje ^Elocution. “ From the fhort account here given of this part of is pronounced long; though that is only rendered fo compofition, it is eafy to perceive what thit\gs are neceffary to render it moft complete and accurate ; which are thefe following. If a word end with a vowel, the next ought to begin with a confonant, or fuch a vowel whofe found may agree well with the former. But if a word conclude with a confonant, either a vowel Ihould follow, or fuch a confonant whofe pro¬ nunciation will fuit with it. And laftly, the fame fyllable ought not to be repeated at the end of one word, and the beginning of the next. It has been obferved by fome critics, that the following verfe at the beginning of Virgil’s iEneid, has all thefe pro¬ perties: Arma virumque cano, Trojae-qui primus at oris. Where any word in this verfe ends with'a vowel, the next begins with a confonant; and where any one ends with a confonant, the next begins with a vowel; and there is no repetition of the fame found through¬ out the whole. But this is what rarely happens, efpecially in our language, which abounds with con- fonants. And what Quintilian fays of the coalition of vowels, in treating upon this fubjeft, feems ap¬ plicable to the whole. “ This” fays he, “ is a thing not much to be dreaded; and I know not whether the negleft of it, or too great a concern about it, be worfe. It necefiarily checks the vigour of the mindj by pofition, and the two following are fo by nature. And again, in the word avarice, we found the firft a long for the fame reafon, and the fecond (hort; con¬ trary to the nature of both thofe vowels. However, we (hall offer a few things that may be of fome ufe to modulate our periods and adjuft their cadency. A great number of monofyllables do not ttand well together. For as there ought to be a greater diftance in the pronounciation between one word and another, than between the fyllables of the fame word ; fuch paufes, though (hort, yet, when too frequent, make the found rough and uneven, and by that means fpoil its harmony. And this may feem more neceffary to be attended to, becaufc the Englifti language abound* fo much with monofyllables. On the contrary, a con¬ tinuation of many long words makes a fentence move too flow and heavily. And therefore fuch periods generally run beft, which have a proper mixture of words of a different length. Befides, as every word has its accent, which with us Hands for quantity ; a number either of monofyllables, or long words, coming together, fo far abates the harmony, as it leflens the variety. Again, feveral words of the fame ending do not Hand well together, efpecially where the accent falls upon the fame fyllable in each of them. For this and diverts it from matters of great importance. And creates too great a jingle by the fimilitude of found ; therefore, as it (hews negligence to permit it, fo to and is apt to difpleafe, from an appearance of affec- be in conftant fear of it difeovers a low genius.” This tation. Of this kind is the following fentence: iVa- was the opinion of that judicious writer.

Such rules are not ap- „ ttt /■)/• re plicable to our language, which has not tjiat accurate HAP. . / ignity. diftin&ion of quantity in its fyllables. For we are Dignity, confifts in the right ufe of tropes and apt to confound accent with quantity, and pronounce figure*. It is not fufficient for an orator to exprefs thofe fyllables longeft, on which we lay the accent, himfelf with propriety and clearnefs,‘or in fmooth and though in their nature they are not fo. As in the harnvsniouS periods; but his language muft likewrfe be & be fulled to tbe nature and importance of the fubjeft. And therefore, as elegance gives rules for the firft of tbefe, and compofition for the fecond; fo does dignity for the lad of them. It is very evident, that different fub- jedts require a different ftyle and manner of expreffion; iince, as Quintilian fays, “ What is magnificent in one difcourfe, would be tm'gid in another; and thofe exprefiions, which appear low upon a fublime fubjeft, would fuit leffer matters: and as in a florid harangue a mean word is remarkable, and like a blemifh ; fo any thing lofty and bright upon a trivial argument is dif- proportionate,and like a tumour upon an even furface.” Now this variety in the manner of expreffion arifes in a great meafure from tropes and figures, which not only enliven and beautify a difcourfe, but give it like- wife force and grandeur; for which reafon this part of elocution feems to have been called dignity. Tropes and figures are diftinguifhed from each other in feveral refpedts. Tropes moftly affedf fingle words, but figures whole fentences. A trope conveys two ideas to the mind by means of one word; but a figure throws the fentence into a different form from the com¬ mon and ufual manner of expreflion. Befides, tropes are chiefly defigned to reprefent our thoughts, but fi¬ gures our pafiions. $ i. Tropes. A trope ks it has been ufually defined, \%, the change of a ’word from its proper fignification to fome other’with advantage. The words, nxiith advantage, are added in the definition, becaufe a trope ought not to be cho- fen, unlefs there is fome good reafon for ufing it ra¬ ther than the proper word. But in what manner, or how far, it can be faid of all tropes in general, that they change the proper fignification of words, will beft appear by confidering the nature of each kind of them leparately. Now in every trope a reference is had to two things, which occafions two ideas, one of the thing expreffed, and another of that thing to which it has a refpedt, and is fupplied by the mind. For all tropes are taken either from things internally related, as the whole and a part; or externally, as caufe and tff<-(ff, fubjeA and adjunct; or from fome fimilitude that is found between them; or from a contrariety. The firft of thefe is called fynecdoche, the fecond metonymy, the third metaphor, and the laft irony. We (hall endea¬ vour to illuftrate this by examples. When we fay, Hannibal heat the Romans; the meaning is, that Han¬ nibal and his army did this. So that altho’ in fome fenfe a part may here be faid to Hand for the whole, which makes it a fynecdoche; yet llrifily fpeaking, the word Hannibal does not alter its fenfe, but there is an el- lipfis in the expreffion, Hannibal being put for him- felf and his army. But if we fay, Cicero Jhould be read by all lovers of eloquence; here indeed the word .Cicero appears to be changed from its proper fenfe, and to fignify the books of Cicero ; which is a meto- vvrny, the author being put for his works; and there¬ fore fuch expreffions need not be deemed elliptical. Again, if any one fpeaking of a fubtle and crafty man, fhould fay he is a fox; the meaning is, he is like a fox; which is a snetaphor, where the word fix retains its proper fenfe, and denotes that animal, to which the man is compared on account of his craft. Laftly, if a_perfon fay to another, Well done; meaning that the thing was HI done, the word •well keeps its own fenfe ;Elocutioi but from the manner of its pronunciation, or fome : other circumftance attending the expreffion, it will be j evident that the contrary is intended : which is called j an irony. From thefe inftances it may appear in what latitude we muff underftand the common definition of i a trope, which makes it to confift in the change of a word from its proper fenfe into fome other. But tho’ in reality there are but four kinds of tropes, which are diftinguiihed by fo many different refpedts which things bear one to another ; yet as thefe feveral re- fptfts are found in a variety of fubjedls, and attended with different circumftances, the names of tropes have from hence been greatly multiplied; which, however, < may all be referred to-fome or other of thofe already mentioned, as will be ffiewn when we come to treat of them in their order. And for diftinftion fake we (hall J calljthe former primary, and the latterfecondary, tropes. We now proceed to confider the rea-fons which have • j occafioned the introduction of tropes. And thefe, as Quintilian obferves, are three; necefity, emphafu, and beauty. 1. Tropes were firft introduced from necefiity, be¬ caufe no language contains a fufficient number of pro¬ per words to exprefs all the different conceptions of our minds. The mind confiders the fame thing vari¬ ous ways ; views it in different lights; compares it with other things; and obferves their feveral relations and • affeCtions; wherein they agree, and in what they dif¬ fer. From ail which reflections, it is furniftied with almoft an infinite number of ideas; which cannot all j of them be diftinguilhed and expreffed by proper words, fince new ones occur daily. And were this poffibie, yet would it be impracticable ; becaufe the multitude of words muft be fo vaftly great, that the memory could not retain them, and be able to recall them as occafion required. Tropes have in a good meafure redreffed both thefe inconveniencies; for by means of them the mind is not burdened with a num- berlefs flock of different words, and yet nothing feems .to want a name. Thus fometimes, where a word is | wanting to exprefs any particular thing, it is clearly enough reprefented by the name of fome other thing, by reafon of the fimilitude between them. At other times, the caufe is fignified by the effeCt; the fubjeCt by the adjunCl; or the contrary. And the whole is often underftood by a part, or a part by the whole. And thus by the ufe of tropes, the mind is helped to conceive of fomething not expreffed, from that which is expreffed. It is much the fame cafe, as when we have occafion to fpeak of a perfon, whofe name we are either unacquainted with, or have forgot; for by de- fcribing his perfon, abode, or fome other circumftances relating to him, thofe we converfe with as well under¬ ftand whom we mean, as if we mentioned his name. So the fhepherd in Virgil, when he could not think of the name of Archimedes, deferibes him by his works: And what’s his name who form’d the fphere, And (hew’d the feafons of the Aiding year? Befides, it fometimes happens in a difcourfe, that thofe things are necefiary to be faid, which, if expreffed in their proper terms, would be o'ffenfive; but being clo¬ thed with metaphors, may be conveyed to the mind with decency. 2. A fecond reafon above-mentioned for the ufe of trope* Part IIL O R A 1 locution, tropes was, emphafis. Tropes do many times exprefs things with greater force and evidence, than can be done by proper words. We receive much the greater part of our knowledge by our fenfes. And fimilitudes taken from fenfible things, as in metaphors, very much aflift the mind in its reflections upon thofe things which do not come under the cognizance of the fenfes. For it is certain, that we are fooner and more ftrongly af- feCted with fenfible objects, than with things of which we can have no ideas but from the internal ope¬ rations of our own minds. Nay, fometimes one bright and lively trope fliall convey a fuller and more juft idea of a thing, than a large periphrafis. So when Virgil calls the Scipios tnm thunderbolts of 'war, he gives a more lively image of the rapid force and fpeedy fuccefs of their arms, than could have been conveyed by a long defcription in plain words. And in many cafes the tropical ufe of words is fo emphatical, and fuited to the idea we defign to excite ; that in this re- fpeCt it may be juftly efteemed the moft proper. So, incenfed 'with anger, inflamed 'with defire, fallen into an error, are all metaphorical expreffions, ufed in a way of fimilitude ; and yet perhaps no proper words can be made ufe of, which will convey a more lively image of the thing we defign to reprefent by them. But beauty and ornament, as was obferved before, have been another caufe of the ufe of tropes. Some fub- je&s require a more florid and elegant drefs than others. When we defcribe or applaud, ornaments of fpeech and a gaiety of expreffion are requifite. And it is the bufinefs of an orator to entertain his hearers at the fame time that he inftruCts them. Now Cice¬ ro, who was an admirable judge of the force and power of eloquence, has obferved, that tropical expreffions give the mind the greateft delight and entertainment. “ I have often wondered (fays he) why tropes fhould give greater pleafure than proper words. I imagine the reafon muft be, either that there is an appearance of wit in negleCting what is. at hand, and making choice of fomething at a diftance ; or that the hearer is furnifhed with a different thought, without being led into a miftake, which affords a very agreeable pleafure ; or that a whole fimilitude is conveyed to the mind by a Angle word ; or that, particularly in the belt and moft lively metaphor, the image is prefented to our fight, which is the quickeft of our fenfes.” And therefore he fuppofes, that “ as garments were firft invented from neceffity, to fecure us from the injuries of the weather, but improved afterwards for ornament and diftinftion; fo the poverty of language firft intro¬ duced tropes, which were afterwards increafed'for de1- light.” Befides, a variety of expreffion is pleafing in a difcourfe. It is many times neceffary that the fame things fliould be repeated ; and if this be done in the fame words, it will grow tirefome to the hearers, and fink their efteem of the fpeaker’s ability. Therefore, to prevent this, it is proper the expreffion fhould be varied, that although the fenfe be the fame, it may give the mind a new pleafure by its different drefs. We come now, in the laft place, to lay down fome directions proper to be obferved in the choice of tropes. And firft, as every trope gives us two ideas; one, of the word expreffed; and another, which, by means of that, the mind conne&s with it; it is neceffary, that the relation between thefe two appear very plain and ’ O R Y. j693 evident. For an obfeure trope is always faulty, un-Elocution, lefs where fome particular reafon makes it neceffary. And therefore tropes ought not to be too far-fetched, left that fhould render them dark. For which reafon Cicero fays, he fhould not choofe to call any thing deftrufttve to a perfon’s fortune, the Syrtis of his pa~ trimony, but rather the rock of it; nor the Charybdis of his eflate, but the gulph of it. For thofe, who ei¬ ther did not know that the Syrtes were two quick- fands upon the coaft of Africa, or that Charybdis was a gulph in the ftreight of Sicily, both of them very ■ deftruClive to mariners, would be at a lofs to under- ftand the meaning of the metaphor. Befides, meta¬ phors taken from things we have feen, affeCi the mind more forcibly than thofe which are taken from fuch things as we have only heard. Now there is fcarce any one who has not feen a rock or a gulph; but there are very few perfbns, comparatively, who have been either at Charybdis or the Syrtes. It is neceffary therefore in a good trope, not only that there be a near affinity between the two ideas, but likewife, that this affinity be very obvious and generally known, fo that the word be no fooner pronounced, but both images do immediately prefent themfelves to the mind. Again, as a trope ought to be very plain and evi¬ dent, fo likewife fhould it bear a due proportion to the thing it is defigned to reprefent, fo as neither to heighten nor diminifh the juft idea of it. Indeed, fometimes, when we fpeak of things indefinitely, we fay too much, left we fhould feem to fay too little. And this manner of fpeaking is called an hyperbole; which is not uncommon in the facred writings. So, for inftance, Saul and Jonathan are faid to be fwifler than eagles, andJlronger than lions. But even in this way of expreffion a proportion is to be obferved. For fome very confiderable and unufual excefs of the thing in its kind is at leaft defigned by it; which perhaps cannot, or however is not ntceffary to be defined. And therefore Quintilian blames Cato for calling the top of an hill a 'wart; becaufe the proportion between the two ideas is no ways adequate. And fo, on the contrary, Ariftotle cenfures Euripides for calling row¬ ing, the empire of the oar. Poets indeed are allowed a greater liberty in this refped. But an orator fhould be modeft in his expreffions, and take care that he neither fo heighten nor diminifh the natural ideas of things by tropes, as to lead his hearers into miftakes. But further : As a moderate ufe of tropes, juftly ap¬ plied, beautifies and enlivens a difcourfe; fo an excefs of them caufes obfeurity, by running it into abftrufe allegories and riddles. Tropes are not the common and ordinary drefs of our thoughts, but a foreign ha¬ bit : And therefore he who fills his difcourfe with a continued feries of them, feems to aft like one who appears in public in a ftrange drefs; which no man of charafter would choofe to do. Moreover, as one ufe of tropes is pleafure and en¬ tertainment, we fhould endeavour to make choice of fuch as are fmooth and eafy. But if at any time we think in neceffary to ufe a harfh trope, it is proper to foften it by fome precaution. For, as Cicero very handfomely fays, a trope Jhould be modeJ},flnce itJlands in a place '•which does not belong to it; for 'which reafon it Jhould feem to come thither by permiflion, and not by force. And therefore, when he thought it harfh to ' 5694 O R A 1 Elacution. fay, The death of Cato made the fenate an orphan; he "* guards the expvefllon by faying, The death of Cato has (if I may he allo’wed to fay ft>) rendered the fenate an orphan. And, to add no more, care fliould be taken how we transfer tropes from one language into another. For as they are frequently taken not only from natural things, or fuch notions as are common to the gene¬ rality of mankind, but likewife from the manners, cu- (loms, and occurrences of particular nations; fo they may be very plain and obvious to thofe among whom they took their rife, but altogether unintelligible to others who are unacquainted with the reafon of them. It was cuftomary for the Roman foldiersto carry their money in their girdles; hence it was the fame thing with them to fay, a perfon had loft bis girdle, as that he had loji his money. And becauie the Romans wore the toga, which was a long gown, in time of peace, and a different garb when engaged in war, their Wri¬ ters fometimes ufe the •vjoxA toga to fignify peace. But as neither of thefe cuftoms is in ufe among us, fo nei¬ ther would the tropes fuit our language, or be gene¬ rally underftood by us. And even in fuch tropes as are taken from the common nature of things, lan¬ guages very much differ. There is a very beautiful trope in the account of St Paul’s fhipwreck, where it is laid. The Jhip was caught, and could not bear up into the wind. The original word, that we tranflate bear up, is ; and properly fignifies, to look, or keep its eyes againjl it; which is a very Itrong and lively image, taken from animate beings, and when applied to men often fignifies to withf and or reftjl: as, av1c?9KXy.e<, torefft an enemy; and Plutarch fays of Demofthenes, that he could not ou/lopSaxyeiv tu ufyvjnu, look againjl or refift the power of money. No¬ thing is more common with Latin writers, than to call men of a public fpirit and true patriots, lumina ct or- namenta reipublicee, that is, the lights and ornaments of the Jlate: And we have borrowed from them the ufe of both thefe metaphors. But becaufe tropes and fi- figures illuftrate and heighten the ftyle, they call them alfo, lumina orationis, or, the lights of a difeourfe. It fometimes happens, that only the tropical fenfe of a word is taken from one language into another, and not the proper fignification of the fame word. So ferupu- lus in Latin properly fignifies a little Jlone, which get¬ ting into the foe hurts a perfon as he walks ; hence it it is applied to the mind, and ufed to exprefs a doubt, or uneafy thought that gives it pain. We have borrowed this latter fenle of the word, but not the former. Art. I. Primary Tropes. s° Metaphor. A metaphor, as ufually defined, is: A trope, which changes words from their proper fgnifi- cation to another different from it, by reafon of fome f- militude between them. But that a word, when ufed metaphorically, does not alter its fignification, but re¬ tains its proper fenfe, was (hewn above. However, it may not be amifs to explain this matter more ful¬ ly, and fet it in a clearer light. Every metaphor, then, is nothing- elfe but a fhort fimilitude. Cicero calls it, a fmilitude reduced to a ftngle word. And Quintilian to the fame purpofe fays, that, “ a meta¬ phor is a (hort fimilitude, and differs from it only in this; that the former is compared to the thing we de- 1 O R Y. Part III fign to exprefs, and the latter is put for it. It is a fi- Elocutiol militude, when I fay of a man, he has afted like a lion ; and a metaphor, when I fay, he is a lion.” J Thus far Quintilian. Now in every fimilitude three i things are requifite : two things that are compared to¬ gether ; and a third, in which the fimilitude or like- 4 nefs between them confifts. And therefore, to keep to this example, when Horace calls a Roman foldier a lion, if the word /few did not retain its proper fenfe, there could be no fimilitude ; becaufe there would not be two things to be compared together with refpeft | to a third, which is neceffary in every fimilitude, and was defigned by this expreflion. The fenfe of which is plainly this : That as a lion feizes his prey with the -jy great eft fiercenefs, fo a Roman foldier with like rage fi and fury attacked his enemies. In the fame manner, | when Cicero calls Pifo the vulture of the province, his I meaning is, that he was like a vulture, or afted in fuch a manner as a vulture a&s, that is, rapacioufly. So that the real difference between a metaphor and a fimilitude confifts in this ; that a metaphor has not | thofe figns of comparifon which are expreffed in a fi¬ militude. But fome perfons have run into miftakes in ] reafoning from tropes of this kind. For they have ] fo argued from metaphorical words, as if all the af- j' feftions and properties of the things expreffed by them might be attributed to thofe other things to which they are applied, and by that means have ftrain- : ed the comparifon (which has ufually but one parti- |l cular view), in order to make it tally in other refpe&s, !' where there is not that fimilitude of ideas. We Will endeavour to make this evident by another example from Cicero, where he calls M. Anthony the torch of theftate. The fimilitude between Anthony and a torch lay in this : That as a torch hums and deftroys every thing within its reach, fo Anthony brought devaftation ■ I and ruin wherever he came. Now a torch has not on¬ ly a property to burn, but alfo to give light; but the fimilitude would not hold in this refpeft, nor was it j I at all defigned. For Cicero never calls a wicked pro¬ fligate man, as Anthony was, the light of the ftate ; j | though he often gives that chara&er to good and vir¬ tuous men, who by their examples do as it were en¬ lighten others, and (hew them the way to be happy themfelves and ufeful to others. But though meta- ;| phors are ufually taken from a fimilitude between two things, as in the inftances here mentioned ; yet fome- ^1 times they are founded in the fimilitude which two . ;| things bear to two others in fome particular refpedt, by means whereof what properly belongs to one of them is transferred to the others the former of which il are called Jimple metaphors, and the latter analogous. . I Hence the rudder of a ihip may be called its reins; for |‘ what the reins are to a horfe, that the rudder is to a i (hip in guiding and directing it. So that here is a | double fimilitude, one between a (hip and an horfe, I and another between the rudder of the former and the reins of the latter ; and from the analogy-between the ] ufe of the rudder to the one and reins to the other, I the reins, which belong properly to the horfe, are ap- I plied to the (hip. Again, fome metaphors are recipro¬ cal, in which the fimilitude holds either way. Thus to fteer and to govern are ufed reciprocally both of a (hip and a ftate: the proper expreffions being, to fteer a Jhip, mb govern a ftate ; and the contrary metaphori- I cal. “ I Partin. /Elocution, cal. But though we fay, the foot of a mountain, bor- ' rowing the fimilitude from animals ; yet we do not fay, on the contrary, the bottom of an animal, meaning his feet; and therefore that metaphor is not reciprocal. From this account therefore of the nature of a meta¬ phor, it maybe faid to be: The application/of a •word by way of fimilitude to feme other thing than what it properly fignifies. And the plainer this fimilitude ap¬ pears, the greater beauty there is in the trope. The ufe of metaphors is very extenfive, as large as univerfal nature. For there are fcarce any two things which have not fome fimilitude between them. How¬ ever, they may all be reduced to four kinds; which was the fecond thing propofed to be confidered. The firft kind of metaphors therefore may be taken from fimilitudes between animate beings. As where thofe things, which properly relate to brutes, are ac¬ commodated to men ; or thofe which belong to men are applied to brutes. Of the former fort is that joke of Cicero : My brother being ajked by Philip, why he barked fe; anfwered, Becaufe he faw a thief. Here larking, the property of a dog, is applied to a man : And the reply does not feem to carry more feverity, or harfhnefs with it, than the queftion. By the latter fort we fay, a crafty fox, and a generous horfe; which are affections that properly relate to men. And to this kind of metaphors may thofe likewife be referred, when that which properly belongs to the fenfes is applied to the mind. Thus we often fay that we fee a thing, when we mean that we underfeand or apprehend it. And in the fame fenfe we fay, that we hear fetch a thing, or perfeon. And by the like manner of expref- fidn, a perfon is faid to frnell out a thing. And thofe who have a genius or difpofition for any art or fcience, are faid to have a tafee for it; and fuch as have entered upon the ftudy of it, are faid to have a touch of it. Thefe ^re common ways of fpeaking in mod languages, and very expreffive of what is in¬ tended by them. And we may alio bring thofe meta¬ phors under this head, by which the properties and affeftions of men are attributed to the Deity: as,-when God is faid to hear, fee, be angry, repent, and the like; which are forms of expreffions very frequent in the fa- cred writings. A fecond kind of metaphors lies between inanimate things, whether natural or artificial, which bear fome fimilitude to each other. And this head is very ex¬ tenfive. Thus we fay, floods of fire, and clouds offmoke, for large quantities. And fo likewife, to infiame an account, that is, to heighten or increafe it; with in¬ numerable others of the like fort. In the two firft of thefe inftances, the terms proper to one element are applied to another; and as thofe elements of fire and water are oppofite to each other, they (hew the exten- „ fivenefs of this trope, that there are no things in na¬ ture fo contrary, but may come within the limits of it, and be accommodated to each other in a way of fimi- j litude. In the laft example, a natural aCUon is applied to what is artificial. A third fort of metaphors is, when inanimate things are applied to animals, on account of fome like pro¬ perties between them. Thus Homer calls Ajax, the bulwark of the Greeks, on account of his valour, which like a wall defended them from the Trojans. And nothing is more common with Cicero, than to brand ill Vol. VIII. 2 5695 men with the chara&er of being the peft of tie fate, Elocution. by reafon of the mifehief which they bring to the pub- lie. So likewife he calls Zeno the philofopher an acute man, for his great difeernment and quick per¬ ception of things; fetching the allufion from metals when brought to an edge or a point. As on the contrary, old Chremes in Terence calls himfelf a feone, for want of apprehenfion. And we fay, a gay perfen, and a bright genius, by this kind of meta¬ phor. The fourth and laft kind of metaphors is that by which the aftions and other attributes of animals are accommodated to inanimate things. Thus Cicero, fpeaking of Clodius, fays: “ The very altars, when they faw that monfter fall, feemed to move themfelves and aflert their right againft him.” Here the words faw, move, and ajfert, are all metaphors taken from the properties of animals. And Virgil, when he would reprefent the impetuous force and rapidity of the river Araxes, fays, it difdained a bridge. And it is a very ufual epithet, which Homer gives to words, to call them or winged, to intimate the fwiftnefs of fpeech. Daftly, as to the choice of metaphors, thofe are efteemed the fineft and ftrongeft, which give life and aflion to inanimate things. The reafon of which is, becaufe they do as it were invigorate all nature, intro¬ duce new forms of beings, and reprefent their images to the fight, which of all the fenfes is the quickeft, moft adlive, and yet moft unwearied. What can be more moving, or in ftronger terms exprefs the villany of Clodius, than when Cicero fays, “ The very al¬ tars of the gods feemed to exult at his death.” And the fame great orator particularly commends thofe me¬ taphors, for their fprightlinefs and vivacity, which are taken from the fenfe of feeing ; as when we fay a bright thought, or a gay expreffion. However, care mult be taken not to venture upon too bold and daring metaphors. Poets indeed claim greater liberty in this refpect, whofe view is often to amufe, terrify, or delight, by heightening the juft and natural images of things. But it is expected the orator fhould reafon coolly, though ftrongly and for¬ cibly : and not by theatrical reprelentations fo tran- fport the mind, as to take it off froKl refledtion, unlefs perhaps on fome particular oecafion. And yet on the other hand, metaphors ought not to fink below the dignity of what they are defigned to exprefs; but the idea they convey ftiould at leaft be equal to the proper word in the place of which they are fubfti- tuted. But there is a very great difference in the choice of metaphors, as they are defigned either to praife or difpraife. One thing may be compared to another in a great variety of refpedts. And the fame thing may be made to appear either noble or bafe, virtuous or vicious, by confidering it in a different light. Such metaphors, therefore, as are chofen to commend, muft be taken from great and laudable things; and on the contrary, thofe which are defigned to difeommend, from things vile and contemptible. Ariftotle gives us a very pleafant example of this in the poet Simonides. A certain perfon, who had carried the prize at a race of mules, offered him a a reward to wiite a poem in ho¬ nour of that action. Simonides thought he did not 32 E bid ORATORY. 5696 ORATORY. Partlll. Elocution, bid high enough; and therefore put him off with fay- ing, the fubjeft was too mean to write in praife of mules which were the offspring of afies. But upon his being offered a larger, fum he undertook the taflc ; and, as Ariftotle obferves, when he has occafion to fpeakof the mules in that poem, he does not mention them by that name, but calls them the daughters of fleet and generous horfes, though he might with as much propriety have called them the daughters of dull ajfes. But it was the poet’s bufinefs, in praifing, to take the moft advantageous part of the chara&er. Where things are capable of fuch different turns, me¬ taphorical exprefiions are generally moft beautiful. And fometimes the fame metaphor may be applied contrary ways, both in praife and difpraife, as it will fuit different properties pf the thing to which it refers. So a dove, in a metaphorical fenfe, may reprefent either innocence or fear; and an iron heart may denote either courage or cruelty ; as an hard head, Jlrength or nneakr refs of thought. And this ambiguity in the applica¬ tion of metaphorical words, often affords occafion for jefts and concife wit. We obferved before, that Ci¬ cero never calls ill men, lights of the fate. But he once in this manner calls Sextius Clodius, the light of the fenate. For, when his kinfman Publius Clodius had been killed by Milo, and his corpfe was brought to Rome, Sextius raifed the mob, and in a tumultu¬ ous manner carried it into the fenate-houfe, where they burnt it, and by that means fet the building on fire : For which feditious aftion Cicero paffes that joke upon him, under the metaphor of light, which elfe* where he always ufes in a good fenfe. But to^ proceed: All forced and harfh metaphors fhould be avoided, the one being no lefs difagreeable to the mind than the other to the ear. Nor fhould they come too thick in a difcourfe. In a word, they ought not to be ufed, but either where a (proper word is wanting, or they are more fignificant or beautiful than the proper word. 51 II. Metonymy. This, as defined by Quintilian, is, the putting one word for another. But Vomus defcribes it more fully, when he calls it, “ A trope, which changes the name of things that are naturally united, but in fuch a manner as that one is not of the effence of the other.” That a metonymy is thus diftinguifh- ed from the other tropes, has been fufficiently fhewn already in the two laft chapters. When it is faid, to put one word for another, or, to change the names of things, the meaning is, that the word fo ufed changes its fenfe, and denotes fomething different from its pro¬ per fignification. Thus, when Mars is put for war, and Ceres for corn, they lofe their perfonal fenfe, and ftand for the effedfs of which thofe deities were faid to be the caufe. So likewife, when Virgil fays, He drank the frothing bowl, the word howl muft neceffarily fignify the liquor in t^e bowl. And when in another place, defcribing the temple of Juno at Carthage, in which the a&ions of the Trojan war were reprefented, and the images of the heroes, he makes ./Eneas, upon difcovering that of Priam among the reft, cry out, Lo here is Priam ;• it is plain the word Priam there muft ftand not for his perfon, but his image or figure. And this property of changing the fenfe of the word appears peculiar to Elocution^ metonymy. In treating upon a metaphor, we obfer- ■* ved the miftake of thofe who teach, that a word ufed metaphorically lofes its proper fignification ; whereas | it only changes its place, but not its fenfe ; being ap¬ plied to a thing to which it does not naturally belong, ; by way of fimilitude. And as the not attending to j this has run fome perfons into very great abfurdities, j in treating upon metaphorical exprefiions, and reafon- J ing from them in the tropical fenfe ; fo the like has happened to others in fome inftances of a metonymy, where, by mifapprehending their true nature, they have reafoned from them in the literal fenfe, as we •Ihall fhew prefently. A metonymy is not fo extenfive I as a metaphor, nor altogether fo neceffary: becaufe | nothing is faid by a metonymy, which cannot be ex- prefled in proper words; whereas metaphors are often ;j ufed for want of proper words to exprefs fome ideas. .However, metonymies are very ufeful in language; for they enrich a difcourfe with an agreeable variety, and give both force and beauty to an exprefiion. And what I we obferved with relation to a metaphor, is true alfo 1 of this trope; that fome metonymies, even in common | difcourfe, are more frequently made ufe of than the proper words in whofe room they are put. So, pale death, a blind way, and a happy fate, are very com¬ mon exprefiions with us. And it is more ufual to fay, This is fuch a perfon's hand, or I know his hand, | than his writing, when we intend this latter fenfe of the word. We now proceed to the divifion of metonymies; | which are commonly diftinguilhed into four kinds, from the different manner in which things are natu¬ rally, but externally, united to one another. Now things are thus united, or one thing depends upon another, either with refpeft to its produftion, or in the j I manner of its exiftence when produced. In the for¬ mer way the effeft depends upon its caufe, and in the latter the adjunft upon its fubjedts. And hence arife four forts of metonymies, which receive their names from the caufe and effe£l, the fubjeft and the ij adjunft. It is called a metonymy of the caufe, when the external caufe is put for the effedl. The external caufe is two¬ fold, the agent and end, which are ufually called the efficient and final caufe. Of the former kind are fuch J metonymies, where the inventor or author is put for what was invented or effefted by him. Thus, as we faid before, CVn?.r is fometimes put forthe ufe of | which Ihe was faid firft to have introduced ; and Mars | for war, over which he was thought to prefide. And by this way of fpeaking, any artift or writer is put for his work. So Juvenal, blaming the luxury and | profufenefs of the Romans, fays: There are few tables , J without Mentor; that is, which were not made by him, or after his manner. And our Saviour fays in the parable of the rich man and Lazarus,* They have Mofes and the prophets; meaning, the books of Mofes and the prophets. But under this fort of metonymy is included not only the agent, ftridUy fo called, but alfo any means or inftruments made ufe of in the do¬ ing of a thing, when put for the thing done. Thus, polite literature is called humanity, becaufe it culti¬ vates and improves the human mind. And in that exprefiion of Cicero, Words move nobody but him who un? ; I PartHI. ORA1 Elocution, underjlands the tongue ; the word tongue, which is the inftrument of fpeech, is put for fpeech, or language. And in the like fenfe, arms are fometimes put for •vear, and tistfnuordiox/laughter. By the fame kind of me¬ tonymy, likewife, any affe&ion or quality is put for its effect. As when it is faid, the end of government is to maintain ju/lice ; that is, fuch mutual offices among men, as are the effetts of jujlice. And fo likewife in that of Cicero, It is the bujinefs of magif rates to check the levity of the multitude; by which he means tumults occafioned by their levity. Moreover, as human af¬ fections are attributed to the Deity in a metaphorical fenfe, fo feveral parts of the human body are likewife afcribed to him by this kind of metonymy. Thus, his hand znd his arm are ufed to exprefs his ponuer; as his ear and eye, his care and providence; thefe being the inftrume'nts of fuch tffedts in mankind. Metonymies of the final caufe are thofe, by which the end in doing a thing is put for the thing done. As when we fay, "The •watch is fet, meaning the ’watchmen, who are ap¬ pointed for that purpofe. And fo likewife that ex- preffion, to make an example, as it fignifies to puni/h, in order to deter others from the like crimes by fuch an example. As alfo that of Virgil, Phillis Ihould garlands crop, by which are meant flo’wers to make garlands. The fecond kind of metonymy puts the effeft for the efficient caufe, whether the agent, or only the means and inftrument. So Virgil calls the two Sci- pios the deflruttion of Libya, becaufe they were the agents who effe&ed it. And Horace compliments his patron Msecenas with the titles of being his guard and honour; that is, his guardian, and the author of his honour. But when Cicero tells the citizens of Rome, that the death of Clodius •was their fafety, he means the occafion only of their fafety. And elfewhere he calls that a dark hope and blind expectation ; the effedl of which was dubious and uncertain to thofe who en¬ tertained it. And in like manner, the fons of the pro¬ phets, when they were eating the pottage which E- lifha had ordered to be fet before them, cried out, There is death in the pot; that is, fame deadly thing, as is prefently after explained. And thus fweat, which is the effedt of labour, is fometimes put for labour. As in the threat denounced againft Adam, In the fweat of thy faceJhalt\thou eat bread; that is, by labour in cultiva-' ting the ground. And, in allufion to this way offpeak- ing, Anthony the orator tells Craffus, “ the improve¬ ment of the ftyleby conftant exercife, as he prefcribed, was a thing of much fweat.And virtue is faid to be gained by fweat, that is, continued care and exercife in fubduing the paffions, and bringing them to a pro¬ per regulation. But in thefe two expreffions there is likewife a metaphof, the effedt of bodily labour being applied to that of the mind. In all thefe inftances, the effedt is put for the efficient caufe. The third kind of metonymy is, when the fubjedt is put for the adjundt. By fubjedt here, in a large fenfe of the word, may be underftood that wherein fome other thing is contained, or about which it is converfant; as likewife the poffeffor with refped): to the thing he poffeffes ; and the tiling fignified, when put for the fign of it. Now, by the firft of thefe ways of fpeaking, the feat of any faculty or affedfion, is ufed for the faculty or affedtion itfelf. So it is ufual to r O R Y. 5697 fay, a man of a clear head, when we mean a clear Elocution, mind or underftanding ; the feat of the mind being in’” the head. And a perfon is faid to have a ’warm heart, becaufe the heart has been thought the feat of the affedtions. In like manner, the place where any ac¬ tions are performed, is put for the adtions done in it. As when Cicero fays, “ Do not always think of the forum, the benches, the roftra, and the fenate meaning the difcourfes which were ufually made in thofe places. So likewife the contrary, or place of refidence, is put for the inhabitants, as in that pafiage of Cicero : “ And to omit Greece, which always claimed the preeminence for eloquence, and Athens, the inventrefs of all fciences, where the art of fpeak¬ ing was invented and perfedted 5 in this city of ours, (meaning Rome), no ftudies have prevailed more than that of eloquence.” Where the words Greece and Athens ftand to denote the inhabitants of thofe places. And hither may alfo be referred thofe expreffions in which the time is put for the perfons living in it; as, the degeneracy of the prefent age, the virtue of former times. In the fecond way above-mentioned, the ob- jedt is ufed for the perfon, or thing employed about it: As when Cicero fays, “ In time of battle the laws are filentwhere by law a thing may be confidered The fourth kind of fynecdoche is, when either the mat- as an whole in three different refpe&s, which logicians ter or form is put for the whole being. Thus fiver and call an unherfdl, ejfential, and integral whole. An £ perfons. Thefe forms of fpeech are called antonomajtd, Elocution.|if and come properly under a fynecdoche; fo. in the for- ~ the whole is put for a part, and in th: alter a part for the whole. Art. II. Secondary Tropes. Secondary tropes are fo called, becaufe they are all of the fame nature with the former, and may be referred to fome or other of them, though they have received different names. They are chiefly eight in number; Antonomcjia, Communication, Litotes, Euphernifm, Catachrefis, Hy¬ perbole, Metalepjis, and Allegory. The three firft of thefe are Ample tropes, and may all be referred to a Synecdoche. But the five laft are of a mixed or com¬ plex nature, and not confined to any one of the pri¬ mary tropes; as will appear in treating upon them in order. I. A common or general word is fometimes ufed for the proper name of fome particular thing or per- fon which upon any account is eminent and remark¬ able. So we fay, He is gone to the city, ox he came frotn the city, that is, London. And by the Scriptures we mean the Bible. So likewife in fpeaking of per¬ fons, the orator is ufed for Cicero, the poet for Homer or Virgil, and thephilcfopher for Ariftotle : and it is not unufual to fay the apojlle, when we mean St Paul. On the contrary, the proper names of things or per¬ fons are fometimes applied tcf any o’her of the fame chara&er. Thus we ufe the word gofpel for any cer¬ tain and undoubted truth. And Carthaginianfaith pro¬ verbially flood for the greateft falfehood and deceit among the Romans. With the Greeks, Hercules fig- nified a ftrong man, Neft or a ■wife man, and Irus a leggar; andthenamesof Samfon, Solomon, and Job, now anfwer the like chara&ers. Both thefe ways of expreflion are often very emphatical, and heighten the idea more than where things are exprefled by their own name. To call a good orator Cicero, or an excel¬ lent poet afecond Virgil, includes not only an encomium from the arts themfdves, but leads the mind to what is moft perfed in them, and was peculiar to thofe II. Nothing is more common with orators, than a change of perfons. Sometimes, to avoid envy, and pre¬ vent the imputation of pride, in affuming to them- felves the praife of any laudable aftion,they aferibe it to their hearers, and do not fay, nve, but^e did fo and fo. At other times, when it is neceflary to remind them of fomething which they have done amifs, or to caution them againft fome wrong ftep for the future; to prevent giving offence, they take it upon themfelves, or at leaft join themfelves with them, and do not fay, you have done this, or do not you do this; but, w have done it, or let us not do it. And again, at other times, in compliment to their hearers, they join them as part¬ ners in the commendable adions or virtues of other perfons; as when the whole body of the people is brought in to fhare the praife arifing from the fuccefs of wife counfels or vidorious arms. Such ways of fpeaking often occur both in Demofthenes and Cicero. They are called communication, and come properly un¬ der a fynecdoche of the whole. III. On the contrary, there is a mode of fpeech, in which, by denying the contrary, more is intended than the words exprefs. This way of fpeaking is call¬ ed litotes ; and is often ufed for modefty fake where a perfon is led to fay any thing in his own praife, or to foften an expreffion which in dired terms might found harfh or give offence. As if one fhould fay, / do not commend you for that; meaning, I greatly dif- commend or blame you for it. Where more being un- derftood than the words exprefsly denote, it is propet* ly a fynecdoche of the part. Not that this manner of fpeaking is always to be fo interpreted; but where it is not, there is no trope; which muft be judged of by the circumftances of the difeourfe. But that it fre¬ quently is fo ufed, might be eafily fhewn from many inftances; though it will be fufficient to mention two or three. Cicero fpeaking of Cotta, calls him no mean orator, whom he had juft called a very great orator.- And he fays of Varro, that, “ he purlued his ftudies not without induftry;” and afterwards gives him the charader “ of a man of the greateft application.” . Which paffages, compared together, plainly (hew the import of thofe negative expreflions. And a friend of Cicero, writing to him, begins his letter thus: “ Al¬ though I am fenfible the news I fend you will not be very pleafant.” This news was concerning thedeafh of another friend of Cicero’s; and there by the words not very pleafant, muft to be fure be meant very un- pleafant and melancholy ; but he chofe that exprefiion in the beginning of his letter, as the fofteft and leaft Ihocking, the better to prepare him for the following account of what that news was. And this way inter¬ preters explain that paffage in St Matthew: And thou Bethlehem in the land of Juda are not the leaft among the princes of Juda ; where, by not the leaft, they underftand the greateft, or very great, upon account of the honour it received by the birth of our Saviour, as the words immediately following plainly intimate. IV. When any difpleafing or ungrateful thing is expreffed by a more foft and agreeable word, it is call¬ ed euphemifm. And as the word made ufe of is either con- 56 iPart III. ORA ocution. contrary to the proper word, or only different from it, ’ it may be referred to different tropes. The Latins have a foft way of expreffing their difregard to a per- fon, by faying valeat; which we have borrawed from them, and fay, fare him 'well. When the contrary being intended to what is expreffed, it comes properly under an irony. And as the word death carries in it an idea that is difagreeable to human nature, inftead of faying a perfon is dead, we often fay he is deceafed, or departed; which we have alfo taken from the La¬ tins, who ufe the words decejjit and obiit, in the fame fenfe. So that in both languages it comes under a fynecdoche of the whole; to depart out of life being one fort of departure. But when the evangelift fpeak- ing of Stephen, who was ftoned to death, expreffes it by faying that he fell afleep ; this is a beautiful meta¬ phor, taken from the fimilitude between the death of a good man and fleep. V. fignifies in general any harfh trope, though it is rnoft commonly found in metaphors. It is principally ufed by poets, who make choice of it for novelty, or to enforce an expreffion, where the pro¬ per word does not feem ftrong enough. As when Mil- ton, in defcribing the angel Raphael’s defcent from heaven, fays, he Sails between worlds and worlds; where the novelty of the word enlivens the image more than if he had faid flies. But it is fometimes found in the graveft authors, and even in the facred writings. So we read of the Hood of the grape. And Solomon fays, the horfe-leech hath two daughters. In all thefe inftances the trope is a metaphor. But when St John fays in the Revelations, I turned to fee the voice that fpake to me, it is here a metonymy of the adjunft; the word voice being put for the perfon who uttered it. In St Matthew we read of Simon the leper; not that he was then a leper, but had been fo, and was cured; which is a fynecdoche of the part. And when a cri¬ minal is faid to have had bis reward, that is, his punifh- ment, it is an Irony. VI. Hyperbole is the boldeft of all tropes; for it ex- 59 ceeds the drift bounds of truth, and reprefents things either greater or lefs, better or worfe, than they really are. But the reprefentation is made in fuch a manner as not to impofe on the hearers. For an hyperbole is not ufed to define or defcribe any thing accurately, but only to magnify or deprefs it in a confiderable de¬ gree, when we either cannot or do not choofe to re- prefent it exaftly. The excefs in this trope is called auxefs ; as when we fay of any thing that is very- high, it reaches to the /kies. The defeft, or contrary extreme, is termed meiofis: So we fay of a very lean perfon, he is nothing but /kin and bones, or a mere /ke- leton. It is principally metaphorical, but fometimes taken from other tropes. When Saul and Jonathan are faid to have been fwifter than eagles, andflronger than lions, the expreffion is founded in fimilitude, and is therefore a metaphor. When, infteadjof faying Cato was a very virtuous man, the hiftor.ian calls him the image of virtue; it is an hyperbolical metonymy of the adjundt for the fubjeft. And when we read in the Mofaic hiftory of cities fenced up to heaven, there is a fynecdoche. But if a man of weak fight be faid to be eagle-eyed, it is an irony. Thofe hyperboles which are expreffed comparatively, are commonly moft em- T O R Y. 5701 phatical, becaufe they fliew a peculiarity in the excefs. Elocution. To fay a thing is as light as a feather, carries the idea very far; but to fay it is lighter, not only carries it ftill farther, but alfo heightens it, by leaving the mind at an uncertainty where to fix the limits. VII. Sometimes two or more tropes, and thofe of 60 a different kind, are contained under one word ; fo that feveral gradations, or intervening fenfes, come be¬ tween the word that is expreffed, and the thing de- figned by it. And this is called a metalepfis. The contefts between Sylla and Marius proved very fatal to the Roman ftate. Julius Caefar was then a young man. But Sylla obferving his afpiring genius, faid of him, “ In one Caefar there are many Mariufes.” Now in this expreffion there is a metalepfis. For the word Marius, by a fynecdoche, or antonomafia, is put for any ambitious and turbulent perfon; and this again, by a metonymy of the caufe, for the ill effe&s of fuch a tem¬ per to the public. So that Sylla’s meaning, divefted of thefe tropes was, that Caefar would prove the moft dangerous perfon to the Roman ftate that ever was bred in it: Which afterwards proved true in the event. So when Virgil, defcribing that part of the African coaft where tineas arrived with his fhips, fays, A dark wood hung over it; the word dark, by a metonymy of the effeft, is put for Jhady, and that again by the fame trope for thick ; for his meaning is, a thick wood. But the words of Dido, in the fame poet, contain a larger gradation, when ffie fays, Happy, ah truly happy had I been, If Trojan fliips our coafts had never feen. In which expreffion, firft by a metonymy of the adjunct, the fliips are put for theTrojans in the (hips; and thefe, by a fynecdoche of the whole, for iEneas, who was one of them ; and again, his arriving on thecoaft, by a me¬ tonymy of the caufe, for her feeing him; and laftly, her feeing him, by the fame trope, for the paffion (he had for him. So that her meaning is, ffie had been happy, if flie had never entertained a paffion for iE- neas. This trope is more frequently to be met with in poets than in orators, as they take greater liberty in ufing diftant allufions than is fuited to that perfpi- cuity of expreffion which is required in oratory. But as Quintilian has well obferved, all the intermediate links of the chain in this trope are of no further ufe than to lead the mind gradually from the firft to the laft, the better to perceive their conneftion. As in the example laft mentioned, relating to Dido, if we drop all the intervening fteps, and connedl the words- expreffed with what is diredtly intended, they will be found to contain a very remote caufe put for the ef¬ fect, which comes under a metonymy. On the contray, in the fecond example, where dark (lands tor thick, the effeft is put for a remote caufe. And the firft, which is founded in a fimilitude of temper between Casfar and Marius, belongs to a metaphor. VIII. Allegory. As a metalepfis comprifes feveral ^ tropes in one word, fo this is a continuation of feveral tropes in one or more fentences. Thus Cicero fays, “ Fortune provided you no field, in which your vir¬ tue could run and difplay itfdfWhere the'words fleld and run are metaphors taken from corporeal things, and applied to the mind. And in another paffage, ("peaking of himfelf, he fays, “ Nor was I fo timorous, that after I had (leered the (hip of the date through* 5702 Elocution, through the greateft ftorms and waves, and brought her fafe into port, I fliould fear the cloud of your fore¬ head, or your colleague’s peftilent breath. I faw other winds, I perceived other (torms, I did not withdraw from other impending tempers; but expofed myfelf fingly to them for the common fafety.” Here the flate is compared to a ihip, and all the things faid of it un¬ der that image are exprefled in metaphors made ufe of to fignify the dangers with which it had been threat¬ ened. And indeed allegories generally confifl of me¬ taphors; which being the moft beautiful trope, a num¬ ber of them well chofen and put together is one of the fineft and brighteft ornaments in language, and exceeds a fingle metaphor in luftre, as a conftellation does a feparate liar. It is true, that allegories are fometimes found in other tropes; but this is very rare. In that known expreffion of Terence, the tropes are all metonymies: Without Ceres and Bacchus Venus grows cold; that is, divefted of the tropes, Without meat and drink, love dies. And Samfon’s riddle is made up of fynecdoches; “ Out of the eater came forth meat, and out of the ftrong came forth fweetnefs.” But there is no fmall fkill required in the right manage¬ ment of allegories. For care fbould be taken, that the fame kind of trope be carried through the whole, fo as to compofe one uniform and confident fet of ideas: otherwife they drefs up a chimera, a thing that has no exidence, and of which the,mind can form no perception. And, as Quintilian fays very judly, “ to begin with a temped and end with a fire, would be very ridiculous and unnatural.” It is likewife very neceflary that the allufions be all plain and evident, efpecially where the name of the thing alluded to is not exprejfed. Thefe are called pure allegories. As that of Cicero: “ So it happens, that I, whofe bufi- nefs it is to repell the darts, and heal the wounds, am obliged to appear before the adverfaries have thrown any dart ; and they are allowed a time to attack us, when it will not be in'our power to avoid theaffault; and if they throw a poifonous dart, which they feem pre¬ pared to do, we fliall have no opportunity to apply a remedy.” The tropes here are all taken from mili¬ tary affairs, without any intimation what they are ap¬ plied to. But that is plain from the context of the difcourfe. For he is fpeaking of the difadvantages he laboured under in defending his client againft thofe of the oppofite fide, and fo applies to the bar thofe terms which were proper to the field. But where the reference is not evident, it becomes a riddle ; which is nothing elfe but an obfcure allegory. To avoid this, therefore, the beft writers generally ufe what they call mixed allegories; that is, fuch wherein the proper name of the thing is expreffed, which the whole fimili- tude refpedts. Of this kind is that in the fpeech of king Philip of Macedon, given us by Juftin, where he fays, “ I perceive that cloud of a dreadful and bloody war arifing in Italy, and a thunder-ftorm from the weft, which will fill all places with a large (bower of blood, wherever the temped of vi&ory (hall carry it.” The proper words war, blood, and vittory, being join¬ ed to the tropes cloud, Jhower,-un&tempeJ}, in this fen- tence, render the feveral parts of the (imilitude plain and evident. Quintilian thinks thofe allegories mod beautiful, where the whole fimilitude is expreffed, and thofe words, which in their proper fenfe relate to one Part Hill of the two things between which the comparifon is Elocutioi|aj made, are allegorically applied to the other: As when Tij Cornelius Nepos lays of Atticus, « If that pilot | gains the greateft reputation who preferves his (hip in a boifterous and rocky fea ; ought not he to be thought a man of lingular prudence, who arrived in ||| fafety through fo many and fo great civil tempefts ?” Thefe are the allegories with which orators are chiefly ijj concerned. § 2. Of Figures. This term feems to have been borrowed from the fit ||| llage, where the different habits and gcftures of the adtors, fuitable to the feveral charadters they fuftained, were by the Greeks called c^^ara, and by the Latins figtiree: And it is not unufual with us to fay of a per- fon, both with refpedt to his drefs and adiion, that he S makes a very bad, or a very gracefid, figure. And as language is the drefs, as it were, of our thoughts, in which they appear and are reprefented to others; fo any particular manner of fpeaking, may in a large fenfe of the word be called its figure, in which lati¬ tudes writers fometimes ufe it. But rhetoricians have reftrained the fenfe of the word to fuch forms of fpeech as differ from the more common and ordinary ways of expreffion ; as the theatrical habits of aftors, and their deporement on the ftage, are different from their ufual garb and behaviour at other times. A figure therefore, in the fenfe it is ufed by rhetoricians, is, A mode of fpeaking different from, and more beautiful and empbatical than, the ordinary and ufual way of exprefs- ing the fame fenfe. Now as the habits and geftures of our bodies are in a manner infinitely variable, fo it is plain that the different forms of fpdech are almoft innumerable. But every alteration from the common manner ought not to be efteemed a figure, nor de- ferves that charadter. It muff contain fome beauty, or exprefs fome paflion, to merit a place among rheto¬ rical figures, and be marked out for imitation. The fubjedl oifigures feems to have been one of the lad things which was brought into the art of oratory in order to complete it. Ariftotle, who treats fo ac¬ curately upon other parts, fays very little of thi*. But the Greek writers who came after him have abundantly fupplied that deficiency. It is to them we owe the chief obfervations, that have been made on this fubjeft. They took notice of the feveral modes and turns of expreflion, obferved their force and beauty, and gave them particular names by which they might be known and diftinguifhed from each other. And indeed they have treated the matter with that minutenefs and fubtility, that Quintilian feems, not without reafon, to think they have multiplied figures to an excefs. But though it was folate before they were taken notice of, and introduced into the art of fpeaking; yet the ufe of them in difcourfe was doubt- lefs very ancient. The author of Homer’s life, which fome have afcribed to Plutrach, has (hewn, by examples taken out of him, that there is fcarce a figure men¬ tioned by rhetoricians, but is to be met with in that moft ancient poet. And, if we confider the nature of fpeech, we fhall eafily perceive that mankind muft have been under a neceffity very early to introduce the ufe of tropes for fupplying the want of proper words to exprefs their Ample ideas: fo the like neceflity muft have ORATORY. PartHI. ORATORY. 5703 elocution, have put them upon the ufe of figures to reprefent their different paffions. Tho’both of them were after¬ wards increafed, and improved in fuch a manner as to become the chief ornaments of language. The paffions of men have been always the fame ; they are implanted in us by nature, and we are all taught to difcover them by the fame ways. When the mind is difturbed, we (hew it by our countenance, by our aftions, and by our words. Fear, joy, anger, alter the counte¬ nance, and occafion different emotions and geftures of the whole body. And we know with what paffion a man is affe&ed, by hearing his words, though we do not fee him. He does not exprefs himfelf as he ufually does at other times when cool and fedate. Objedts appear to him in a different view, and therefore he cannot but fpeak of them in a different way. He in¬ terrogates, he exclaims, he admires, he appeals, he invokes, he threatens, he recalls his words, repeats them, and by many other different turns of expreffion varies his fpeech, no lefs than his countenance, front his common and ordinary manner. Now as nature feems to teach us by thefe figurative expreffions how to reprefent the different commotions of our minds, hence fome have thought fit to call figures the language of the paffions. And as thefe are given us, among other wife ends, to excite us the better to provide for our prefervation and fafety, this is done fometimes by force of arms, and at other times by difcourfe. And therefore Cicero very handfomely compares the con- duft of an orator to the exercifes of the palseftra : in which, as each Combatant endeavours not only to de¬ fend himfelf, and attack his adverfary, but likewife to do both with decency ; fo the principal weapons of an orator, as he reprefents them, are figures, which being no lefs the ornaments of language than images of our paffions, anfwer all thefe purpofes. Befides, figures chiefly diftinguifh the different kinds of ftyle, furnilh it with an agreeable variety, and often ferve to feprefent things in a clear and forcible manner. From this (hort account of the nature of figures, the advantage of them to an orator is very evident. They are a fort of natural eloquence, which every one falls into without attending to it, fuitably to that temper o mind, with which he is affefted himfelf, and is defirous to affeft others. In a cool and fedate dif¬ courfe, fuch figures as convey our fentiments with the greateft ftrength and evidence are mod proper. And there are others, which are fuited to brighten and en¬ liven more gay and fprightly fubje&s. Others again are more peculiarly adapted to exprefs the diforders and perturbations of the mind. To repeat the fame thing again would many times, be deemed a tautology and impertinent ; but to do this when the mind is ruffled, is not only allowable, but the repetition ren- j. ders it more ftrong and affefting. So likewife to in¬ terrogate, exclaim, or admire, under the influence of a paffidn, impreffes the hearers, and difpofes them to attention ; whereas at another time perhaps fuch ways of fpeaking would fcarce be confident with prudence. There is a natural fympathy in mens minds, which difpofes them to receive impreffions from thofe with whom they converfe. Thus one gay and pleafant companion gives a chearfulnefs and vivacity to a whole company whereas on the contrary, one who is dull and flegmatic damps the fpirits of all about Vol. VIII. i him, and affefls them with the fame gloomy temper. Elocution- Figures are peculiarly ferviceable to an orator for an- “ fwering thefe different intentions. And as he finds them in life, from thence he mud copy them ; as a paintSIr does the features of the countenance, and the feveral parts of the body ; figures being to the one what lines and colours are to the other. The defign of Catiline to dedroy the Roman date and burn the city, is a dory well known. There was an army drawn to¬ gether at a proper didance to favour the undertaking; and others were left in Rome, who had their parts affigned them for burning the city, and dedroying thofe who (hould efcape the flames. And in a word, every thing was ready for putting in execution this horrid and barbarous fcheme. So that nothing re¬ tarded it but the taking off Cicero, who was then counful, which was thought neceffary to be done firft. Cicero, upon information of the defign againd his life, finds means to prevent it, and the fame day calls together the fenate. And Catiline, who was a man of confummate boldnefs, had the confidence to ap¬ pear in that affembly. Upon their meeting, Cicero opens to them the whole affair of the confpiracy, and the defign againft himfelf, in a mod warm and pa¬ thetic harangue. In which he had two things in view; to raife the indignation of the fenate againd: the confpirators, and particularly againd Catiline; and, either by terrifying or exafperating him, to oblige him to leave the city. Now he does not begin this fpeeeh in his ufual manner at other times, by addreffing to his audience, befpeaking their favour and attention, or letting them gradually into the de¬ fign of what he was about to fay ; but as Catiline was prefent, he immediately falls upon him with vehemence, in the following manner : “ How far, Catiline, will you abufe our patience? How long will your fury infult us ? What bounds will you fet to your unbridled rage ? Does neither the night guard of the palace, nor the city watch, nor the peoples fear, nor the agreement of all good men, nor the meeting of the fenate in this fortified place, nor the countenances and looks of this affembly, at all move you ? Do not you perceive your defigns are difeo- vered, and that all who are prefent know of your con- fpracy ? Who of us do you think is ignorant of what you did the lad night, and the night before, where you was, who were with you, and what you refolved on? O times, O manners! The fenate knows this, the eonful fees it; and yet this man lives!—-lives ? nay, comes into the fenate, joins in the public counfeis, obferves and marks out each of us for dedruftion!” And in the fame impetuous drain he proceeds through bis whole fpecch, interfperfing a great variety of the like drong and moving figures. And the difcourfe had its defired effeft: for when Catiline dood up afterwards to make his defence, the whole fenate was fo inflamed, and their refentments againd him roie fo high, from what Cicero had faid, that they had not patience to hear him fpeak ; upon which he left both them and the city. Had Cicero, indead of venting his jod indignation againd the author of fo barbarous and inhuman a defign, in the manner he did, by figures fuited to drike the paffions of his hearers ; had he, initead of this, attempted to reafon with him, and told the dory in a cold and lifelefs manner, he would have 3 2 F expofed S7°4 Elocution, expofcd hlmfelf to the contempt of Catiline; and by ' " ^"leaving the fenate liitle or nothing moved at what he faid, prevented perhaps their coming to thofe fpeedy and vigorous refolutions which were neceS'ary at fo critical a juncture. Let us fuppofe him to have expoftulated with Catiline in much the fame words as tcfore, but thrown into a different form, and divefted of thofe pathetic figures. As thus: “ Catiline, you have really abufed our patience to a great degree. You have infulted us with your furious proceedings a long while. You feem to .have fixed no bounds to your unbridled rage. Neither the night-guard of the palace, nor the city- watch, nor the peoples fear, nor the agreement among good men, nor the calling together of the fenate in this fortified place, nor the counte¬ nances and looks of this affembly, appear to move you in the leaft. I affure you we are all of us apprifed of what you did the laft night, and the night before, where you was, and who were with you, and what re¬ folutions you came to. Thefe are fad times, the age is very degenerate ; that the fenate fhould know all this, the conful fee it; and yet that this man fliould live, come into the fenate, hear all our debates, and mark us out to deftroy us.” You fee the fenfe is en¬ tirely the fame, and the words too in a great meafure ; fo that there is little more than an alteration in the form of them. And yet who does not perceive how flat and languid fuch a way of talking muft have appeared at that time ? and how much it lofes of that ipirit and energy, which (hews itfelf in Cicero’s manner of ex- preffion ? Had he delivered himfelf thus, it might in¬ deed have made the fenate look upon Catiline as an abandoned wretch, loft to all virtue and goodnefs, and perhaps have moved fome to pity him on that account; as we are eafily induced to compalfionate perfons in fuch circumftances, efpecially when defcended from noble and virtuous anceftors, which was his cafe. But fnre it would have been ill fuited to fire their minds with that generous regard for their country, and the neceffary precautions for its fecurity, which the cir¬ cumftances of the date then required. Nor would Catiline have been at all deterred by it, but rather en¬ couraged in the profecution of his defigns, from the little effeft a fpeech fo managed muft probably have had upon the minds of the fenators. But Cicero knew very well, that the paffions of mankind are the fprings of adtion: that it is many times not fufficient for an orator to convince their minds, by fetting the truth in a clear light; but he muft alfo raife their hopes, alarm their fears, inflame their anger, or ex¬ cite fome other fuitable pafiion, before they will be brought to aft 'with that zeal and fervour, which the cafe may require. And as he was admirably well (killed in this art of touching the paffions, he feldom fails to fix upon the proper methods of doing it, and makes choice of fuch figures and modes of (peaking as in the ftrongeft manner reprefent the emotions of his own mind. For every paffion is not to be exprefled by the fame figures, any more than it is drawn by the fame lines, or painted with.the fame colours. When Dido finds that iEneas is about to leave her, (he ufes all her arts to detain him. And as perfons in great diftrefs are feldom at a lofs to exprefs their condition sn the moft affefting way; (he difcovers her fear, anger, revenge, with the whole crowd of diforders Part III. which then poflefled her mind, in a variety of moving Elocutiom figures, fuited to raife the counter paffions in his r‘ breaft, as is finely reprefented by Virgil in that artful fpeech he has made for her, which we forbear to re¬ cite for no other reafon but the length of it. But what particular figures are moft accommodated to an- fwer the-feveral ends propofed by them, will beft ap¬ pear when we come to*treat of them feparately. We (hall therefore now proceed to lay down a few direftions for the proper ufe of figures. And firft they (hould always be accommodated to the fentiments, and rife in proportion to the images defigned to be conveyed by them. So far as they ^re founded in reafon, they are fuited to imprefs the mind ; but where the language outftrips the thought, though it may pleafe the ear, and fome weak perfons may be carried away with a pomp of words, yet an intelligent hearer will foon fee through the thin and airy drefs. It is the fenfe which gives weight to the figure, as that by ftriking the imagination awakens the mind, and excites it to aft in conformity to reafon. Again, in the ufe of pathetic figures, it is generally better to be nervous than copious, that the images, by their clofer union, may imprefs the mind with greater force and energy; though in fuch figures as are deugned for ornament or illuftration, a more diffufive way of painting is fometimes agreeable. But farther, the too frequent ufe of figures ought to be avoided. For what was obferved in relation to gropes, is alfo true with refpeft to thefe ; that a great number of them is apt to darken and obfcure the ftyle. And befides, Ci¬ cero’s refleftion in this cafe is very juft, That “ it is hard to fay, what (hould be the reafon, that’ thofe things, which moft affeft us with a fenfible pleafure, and at firft fight fooneft move us, do likewife fooneft cloy and fatiate us.” But that it is fo, we find by common experience. Laftly, figures (hould be fo interwoven in a difeourfe, as not to render the ftyle rough and uneven, fometimes high and at other times low; now dry and jejune, then pompous and florid. In a word, they (hould rather feem to arife from nature than art ; to offer themfelves, than to be the effeft of ftudy ; and to appear not like patches upon a face, but the agreeable beauty of a found and healthful complexion. But of this we (hall have occafion to fpeak more at large hereafter, in treating upon the different kinds or charafters of ftyle. As to the divifion of figures, which is what remains to be confidered, they are ufually divided into two forts, figures of words, and figures of fentences. Tbe difference between them confifts in this ; that in the former, if you alter the words, or fometimes only the fituation of them, you deftroy the figure ; but in the latter the figure remains, whatever words are made ufe of, or in what manner foever the order of them is changed. Thus when the name of a perfoti or thing is repeated, to intimate fome known property or quality belonging thereto, it is a verbal figure called place. Cicero was a true patriot and hearty lover of his country. And therefore we /hall ufe this , figure in faying, that the time of Catiline's con- fpiracy Cicero appeared like Cicero. The fenfe would remain the fame, but the figure would be loft, if we (hould alter the words, and fay, at that time Cicero, appeared like hitnfelf. So when two or more fentences,. or ORATORY. Part III. ij Elocution, or members of a fentence, end with the fame word, i “ it is called epiftrophe ; as when we fay, To lofe all re- UJh of life, is in effetl to lofe life. But if only the or¬ der of the words be changed in the latter claufe thus, To lofe all relif} of life, is to lofe life in effett; the figure vanifhes. And this is the nature of the verbal figures. But it is not fo in figures of fentences ; they continue the fame, whatever alterations are made in the words. An orator fometimes thinks it proper to change the form of his difcourfe, and addrefs himfelf to his audience, or an abfent perfon, or elfe perhaps to introduce fome other perfon as fpeaking to them, whofe words may be fuppofed to carry greater weight and authority with them than his own. The former of thefe is called apojlrophe, and the latter profopopceia or imagery ; which require no certain words, or order I ■ of expreffion. Art. I. Verbal Figures. These may be diftinguifhed into three forts, as they con fid in a deficiency of words, a redundancy, or a repetition. I. Of the firft fort are ellipjis and afyndeton. fa Ellipfis, is when one or more words are wanting in a fentence, to complete the conftru&ion, and fully ex- prefs the fenfe. This figure is often ufed in proverbial fpeeches: as when we fay, Many men, many minds : that is, have many minds; and, The more danger, the ' more honour, that is, gains more honour. But where more is intended by fuch exprefiions than mere brevity, and efpecially when they are the effeft of fome paffion* the figure receives another name, and is called apofio- pejis, which is placed among the figures of fentences, where we (hall confider it. , (jj Afyndeton, is when the particles that conncft the members of a fentence one with another are left out, to reprefent either the celerity of an a&ion, or the hade and eagernefs of the fpeaker. Thus Cas- far exprefles his fpeedy conqueft of Pharnaces: 1 came, I fain, I conquered. If he had inferted the copula¬ tives, and faid, 1 came, and I faav, and I conquered: it would have retarded the expreffion, and not given to full and juft an idea of the fwiftnefs of the aftion. In the laft article we took notice of the vehement and impe¬ tuous manner in which Cicero attacked Catiline in his firft oration, where his defign was to fire the minds of the fenate againft him, and oblige him to leave the city; both which points he gained by that fpeech. The next day therefore, when Catiline was gone, he calls together the body of the citizens, and makes a fpeech to them, which in a fort of rapture or tranfpoft of mind he thus begins, by acquainting them with the departure of Catiline, He is gone, departed, efca- ped, broke out; intimating at the fame time both the exceffive rage in which Catiline Ifcft Rome, and the great pleafure with which he was himfelf affefled on that account. This concife way of fpeaking adds like- wife a confiderable emphafis to an expreffion, and by bringing the feveral parts of a thing nearer together affe&s the mind with greater force. Thus Cicero fets Cato’s charadter in a very ftrong and beautiful light by the ufe of this figure. “ Nature itfelf (fays he) has made you a great and excellent man for integrity, gravity, temperance, magnaminity, juftice, in a word, for all virtues.” J7°5 II. The fecond fort of verbal figures is contrary Elocution, to thefe, and confifts in a redundancy or multiplicity of words; which are likewife two, pleonafmus and po- lyfyndeton. When we ufe more words than are neceffary to ex- 64. prefs a thing, it is called pleonafmus. This is done fometimes for greater emphafis, as when we fay, Where in the world is he ? At other times it is defigned to af- cetuain the truth of what is faid : So the fervant in Terence, when the truth of what he had related was called in queftion, replies, It is certainly fo, I faw it with thefe very eyes. When the feveral parts of a fentence are united by 65 proper particles, it is called polyfyndeton. This adds a weight and gravity to an expreffion, and makes what is faid to appear with an air of folemnity ; and by re¬ tarding the courfe of the fentence, gives the mind an opportunity to confider and refleft upon every part di- ftindly. We often meet with this figure in Demoft- henes, which very well fuits with the gravity of his ftyle. So he encourages the Athenians to profecute the war againft king Philip of Macedon, from this confideration, that now “ they had (hips, and men, and money, and. ftores, and all other things which might contribute to the ftrength of the city, in greater number and plenty than in former times. Every ar¬ ticle here has its weight, and carries in it a proper mo¬ tive to animate them to the war. And if you remove the copulatives, the fentence will lofe much of its force. III. The third kind of verbal figures confift in a re¬ petition. And either the fame word in found or fenfe, is repeated; or one of a like found, or fignification, or both. Ofthe former fort there are ten, called antanacla- fs, place, epizeuxis, climax, anaphora, epiflrophe, fym- ploce, epanalepfis, anadiplqjis, and epanodos. The two firft of thefe agree in found, but differ in fenfe; the eight following agree in both. When the fame word in found but not in fenfe is re- 6S peated, it is called antanaclafis. This figure fome¬ times carries a poignancy in it; and when it appears na¬ tural and eafy, difeovers a ready turn of thought. As when a fon, to clear himfelf of fufpicion, affured his fa¬ ther he didnot wait for his death ; his father replied. But I defire you would wait for it. Here the word wait is taken in two different fenfes. It is likewife ufed on ferious occafions, as in grave and moral pre¬ cepts, which are apt to affeft the mind with greater pleafure when delivered in an agreeable drefs. As this ; Care far thofe things in your youth, whiah in old age may free you from care : Where the word care in the former place fignifies to provide, and in the latter anxiety of mind. And even our Saviour himfelf once ufes this figure, when he fays to one of his difciples, who defired to be difmiffed from attending him that he might go and bury his father; Follow me, and let the dead bury their dead: Where dead in one place denotes a natural death, and in the other a moral or fpiritual death. Sometimes the name of fome perfon or thing is re- peated again, to denote fome particular charadler or * property defigned to be expreffed by it; and then it is called place. Thus Cicero fays, Toung Cato wants experience, but yet he is Cato ; meaning he had the 32 F 2 ftcady ORATORY. 5706 O R A T Elocution, fteacly temper of the family. And fo in the pro¬ verbial expreffion: An ape is an ape, drefs him ever fo fine. When a word is repeated again with vehemence in the fame fenfe, it is called This figure (hews O R Y. Partin. and your anceftors have undergone the greateft la- Elocution, hours ?” Epifirophe, is contrary to the former, and makes the repetition at the end of each member or fentence. As thus : Since concord ’was loji, friendjhip •was loft. of mind about what he fays ; and therefore has tural tendency to excite the attention of the audience. It is fuited to exprefs anger, furprize, forrow, and fe- veral other paffions. As when Cicero would exprefs his indignation againft Anthony for having been the chief inftrument in bringing on the civil war, he fays to him : Ton, you, Anthony, pufhed Cafar upon the civil war. And thus he tells Catiline in his firlt invec¬ tive againft him : I'ou live; and live, not to lay aftde, hit to purfue, your wicked deftgn. And when our Sa¬ viour would exprefs his great concern and forrow for the wickednefs of the Jews, he does it in this pathetic manner: 0 Jerufalem, Jerufalem, who killeft the pro¬ phets ! Climax, is a beautiful kind of repetition, when the word, which ends the firft member of a period, be¬ gins the fecond, and fo through each member, till the whole is finifned. There is a great deal of ftrength as well as beauty in this figure, where the feveral fteps rife naturally, and are clofely cpnnedted with each other. As in this example : Thfte is no enjoyment of no good thing who has virtue.” The figi property ’without government, no government without a magiftrate, no magiftrate without obedience, and no obedience where every one ads as he pleafes. But, as Quintilian obferves, this figure lies fo open, that it is apt to look too much like art ; for which reafon he advifes not to ufe it often. To prevent this, therefore, do nothing, (fays Cicero to Catiline,) you attempt nothing, you think nothing, but what I not only hear, but alfo fee, and plainly perceive.” It is fre¬ quently ufed by way of queftion ^ which renders it not . , only beautiful, but likewife ftrong and nervous. As ing it backwards, fo that it takes in the two laft fi- ''*• the beginning of the fame fpeech : “ Does neither gures; for it both begins and ends with the fame word, came to his own, and his own received him not. This figure generally fuits belt with grave and folemn dif- courfes; is the inverfion of a fentence, or repeat- the night-guard of the palace, nor the city-watch, nor the peoples fear, nor the agreement of all good men, nor the meeting of the fenate in this fortified place, nor the countenances and looks of this affembly, at all move you ?” And in another of his orations : u What is fo popular as peace, which feems to afford a pleafure, not only to beings endowed with fenfe, but even to inanimate nature ? What is fo popular as li¬ berty, which even beafts as well as men feern to covet and the fame word is likewife repeated in the middle. This turn of expreffion has a beauty in it, and (hews area- dinefs of thought. We have the following example of it in Minutius Felix, where he is expofing the folly of the Egyptian fuperftition. “ Ifis (fays he) with Cy- nocephalus and her priefts, laments, bemoans, and feeks her loft fon ; her attendants beat their breafts, and imitate the grief of the unhappy mother ; in a little time the fon is found, upon which they all re¬ am! prefer above all things ? What is fo popular as joice. Nor do they ceafe every year to lofe what cafe and leifure, for the enjoyment of which you they find, or to find what they lofe. Aad is it not ri- di- 71 the earneftnefs of the fpeaker, and his great concern fidelity was loft, liberty was loft, all was loft. And Cicero, in the charge which he brings againft Mark Anthony before the fenate, makes ufe of this figure, when he fays, “ Do you lament the deftrudion of three Roman armies ? The author of that deftrudion was Anthony. Do you bewail the lofs of moft emi¬ nent citizens ? They have been taken from you by An¬ thony. Is the authority of this order weakened ? It is weakened by Anthony.” Symploce in both thefe laft figures. As in that of Cicero: “ You would pardon and acquit him, whom the fenate hath condemned, whom the people of Rome have condemned; whom all mankind have con¬ demned.” Here the feveral members both begin and end with the fame word. We have a beautiful in- ftance of it in St Paul, when he fays: “ Are they Hebrews ? fo am I. Are they Ifraelites ? fo am I. Are they the feed of Abraham ? fo am I.” When a fentence concludes with the word with which it began, it is called epanalepfts. As in that expref¬ fion of Plautus, “Virtue contains all things, he wants i a. 1.r ...1.v,«» 't1 1.„ £l r- *r ^ 1 the fame, but the principle not fo honeft, in the advice which we find given by themifer in Horace, when he fays, “ Get money if you can, honeftly ; but however, get money.” This figure adds a force to an expref¬ fion, when the principal thing defigned to be convey¬ ed is thus repeated, by leaving it laft upon the mind. orators fometimes difguife it, by not repeating the fame And it heightens the beauty of it, when the fentence word which flood in the former member, but fome has an agreeable turn arifing from two oppofite parts, other equivalent to it. As in the following inftance As in Cicero’s compliment to Csefar : “ We have feen of Cicero for Milo : “ Nor did he commit himfelf on- your viclory terminated by the war; your drawn ly to the people, but alfo to the fenate; nor to the fword in the city we have not feen.” Hermogenes fenate only, but likewife to the public forces; nor to calls this a circle, becaufe the fentence returns again thefe only, but alfo to his power with whom the fe- to the fame word, as that geometrical figure is form- nate had entrufted the whole commonwealth.” ed by the orbicular motion of a line to the fame When feveral fentences, or members of a fentence, point, begin with the fame word, it is called anaphora. This When the following fentence begins with the fame is a lively and elegant figure, and ferves very much to word with which the former concluded, it is termed engage the attention. For by the freqnent return of anadiplofts. As in the following inftance: Let us the fame word the mind of the hearer is held in an think no price too great for truth ; truth cannot be agreeable fufpence, till the whole is finiftied. “ You bought too dear. So in that paffage of St John : He i|Part III. i locution, diculous to lament what you worfhip, or to worfhip rf what you lament ?” It ferves likewife to illuftrate and enforce the fenfe, by fetting it in two oppofne views. As in that exprefiion of the prophet: “ Wo unto SIB them who call good evil, and evil good ; who put darknefs for light, and light for darknefs 1” Thofe figures which confift in a repetition of words | of a like found or fignification, or boll?, are four ; paror.omafia, . homoioptoton, fynonyrrria, and dcriva- tio; the two firft of which refpe<£l words that are fitnilar in found only, the third in fenfe, and the laft 1 in both. •I When two words very near in found, but different in fenfe, refped each other in the fame fentence, it is called paronotnafta. As when we fay, After a feajl comes a faff ; and, A friend in need is a friend in~ Ideed. We gfually call it a pun; which when new, and H appofitely ufed, paffes for wit, and ferves to enliven converfation. Nor is it wholly to be excluded from grave and ferious difcourfes : for a witty jeft has many times had a better effedt than a folid argument, and prevailed with thofe who could not be moved by clofe reafoning. And therefore Cicero and the beft fpeak- ers have fometimes recourfe to it upon weighty and fo- j . lemn occafions, as will be fhewn hereafter in its pro- I per place. yi When the feveral parts of a fentence end with the fame cafe, or tenfe of a like found, this alfo is confi- dered as a figure, and named homoioptoton. As thus: No marvel though nnifdom complains that fie is either ’wilfully defpifed, or carelefly neglefied; either openly fcornedt or fecretly abhorred. This figure is efteemed moft beautiful when the parts are all of the fame length, or pretty near it; as it adds to the harmony of the period, and renders the cadency of the feveral members more mufical from the juft proportion be¬ tween them. The Greek rhetoricians were much ad¬ duced to this figure, and Ifocrates is particularly ce- 4 lebrated for it. But fome of the beft orators feem to have induftrioufly avoided it, as carrying in it too much the appearance of art. And it is remarkable, that this figure appears nowhere fo much in all the works of Demofthenes, as in an oration, which he did not fpeak himfelf, but wrote for his friend Diodorus, a man of that tafte, who was to pronounce it as his own. j g The next figure above-mentioned is fynonymia. Now ^ ftriftly fpeaking, fynonymous words are thofe which have exactly the fame fenfe. But there being few fuch, the ufe of the term is fo far extended as to com¬ prehend words of a near affinity in their fignification, which in'difcourfe are frequently put for one another. So, to defire, and intreat, are fometimes ufed as equi¬ valent terms; whereas to defre is no moi-e than to wiih for a thing, and to intreat is to exprefs that in¬ clination in words. In like manner, efeem and honour, are often taken for fynonymous words, though they have not precifely the fame fenfe, but one is the ufual |l confeqUence of the other; for efteem is the good opi¬ nion we entertain of a perfon in our mind, and ho¬ nour the outward expreffion of that opinion. When two or more fuch words come together, they confti- tute this figure. As when Cicero fpeaking of Pifo |, fays, “ His whole countenance, which is the tacit language of the mind, has drawn men into a miftake, | and deceived, cheated,, impofed on thofe who did not 5707 knowjiim.” This figure fometimes adds force to an Elocution, expreffion, by enlivening the idea ; and it often pro- ’ motes the harmony and juft cadency of a fentence, which otherwife would drop too foon, and difappoint the ear. When fuch words as fpring from the fame root, as 79 jufice, jufi, injuflice, unjufi, and the like, come toge¬ ther in the fame fentence, they make the figure call¬ ed derivatio. Cicero obferving the vanity of the philo- fophers, who affefted praife at the fame time that they decried it, ufes this figure, when he fays of them, “ The philofophers fet their names to thofe very books which they write for the contempt of glory ; and are defirous to be honoured and applauded, even for what they fay in contempt of honour and ap- plaufe.” This figure receives an additional beauty when repeated, efpecially in two oppofite members; as, He •wifhed rather to die a prefent death, than t* live a miferable life. Art. II. Figures of Sentekces. Of thefe, fome are principally adapted for reafon* ing, and others to move the paffions. I. Thofe fuited for proof. AVhich are fix: Prolepfs, hypohole, anacoinofts, epitrope, parabole, and antithefs. Prolepfts, or anticipation, is fo called, when the g* orator firft ftarts an objeftion, which he forefees may be made either againft his conduit or caufe, agd then anfwers it. Its ufe is to foreftall an adverfary, and prevent his exceptions, which cannot afterwards be in¬ troduced with fo good a grace. Though it has like¬ wife a farther advantage, as it ferves to conciliate the audience, while the fpeaker appears defirous to repre- fent matters fairly, and not to conceal any objection which may be made againft him. The occafions of this figure are various ; and the manner of introdu¬ cing it very different. Sometimes the orator thinks it neceffary to begin with it, in order to juftify his con— duft, and remove any exceptions which may be made againft his defign. Cicero for feveral years together, after he firft began to plead, had always been for the defendant in criminal cafes. And therefore, when he was prevailed with to undertake the accufation of Verres, he begins his oration with this apology for himfelf: “ If any one prefent fhould wonder, that when for feveral years paft I have fo conduced my- felf as to defend many and accufe none, I now on a fudden alter my cuftom, and undertake an accufation; when he /hall have heard the occafion and reafon pf my defign, he will both approve of it, and think no perfon fo proper to manage this affair as myfelf.’5 And then he proceeds to give an account of the rea- fons which moved him to engage in it. At other- times the obje&ion is admitted as an exception to what has been faid, but not fo as to affedt it in gene¬ ral. Thus, when Cicero has reprefented the advan¬ tages of literature and the polite arts, he Harts this objedtion to what himfelf had faid, “ But fome one will afk, whether thofe great men,- the memory of whole glorious adtions is delivered down to pofterity, were acquainted with that fort of learning I fo ap¬ plaud?” To which he replies, “ Indeed this can fcarce be faid of them all. However, the anfwer is eafy. I have known feveral perfons of excellent abilities, who,- without learning, by the force of an extraordinary ge¬ nius. ORATORY. 57°8 Elocution, nius, ^ave been men of great virtue and folidity. Nay 'I will add, that nature without learning, has ofteuer produced thefe qualifications, than learning without a genius. But yet it muft: ftill be owned, that where both thefe meet, they form fomething very excellent and lingular.” Again, at other times, the orator art¬ fully reprefents the objedion as fomething confider- able and important, to give the greater weight to his anfwer when he has confuted it. Cicero, in his cele¬ brated oration for the Manilian law, could not omit to take notice, that Lucullus had already gained fe- veral very confiderable advantages over Mithridates. And therefore, having before defcribed the war as very great and dangerous, apprehending thefe two ac¬ counts might appear fomewhat inconfiftent, and be liable to an obje&ion; he puts it thus artfully himfelf: “ But now, after what I have faid of Lucullus, it may probably be afked, How then can the war be fo great ? Be pleafed to hear, for there feems to be very juft reafon for this queftion.” And then he proceeds to fhew, from the power of king Mithridates at that time, his great abilities, long experience in military affairs, and frefh alliances, that the war was yet very great and dangerous. But fometimes, when the orator is fenfible that what he has advanced lies open to an ob- je&ion, he omits to make it in exprefs terms; and yet proceeds to vindicate what he had faid, as if it had been made. Thus, when Cicero had charged Verres with having plundered the inhabitants of Sicily of all their plate, jewels, and other valuable moveables, which he thought worth while to carry away ; as the audi¬ ence might imagine this to be fcarce credible, he takes it for granted they thought fo; and therefore imme¬ diately adds, “ As ftrange as this is, I affirm it po- fitively, without any intention to aggravate the crime.” And fo he goes on to the proof pf his affertion. But this figure is likewife made ufe of to guard againft fome objection, which the fpeaker apprehends may be made againft what he defigns to fay. And thus Ci¬ cero ufes it in his oration for Sextius. “ My province, (fays he) as I fpeak laft, feems to call for affedtion to ' my friend, rather than his defence; complaint, rather than eloquence; expreffions of grief, rather than art. And therefore, if I fhall exprefs myfelf with more warmth, or greater freedom, than thofe who have fpoke before me, I hope you will grant me all that li¬ berty of fpeech which you judge reafonable to be al¬ lowed to an affedtionate forrow, and juft refentment.” This figure requires great prudence and difcretion in the management of it. The fpeaker muft conlider well the temper, bias, and other circumftances of his hearers, in order to form a right judgment what parts of his difcourfe may be moft liable to exception. For to obj df fuch things, which the hearers would never have thought of themfelves, is to give himfelf a need- lefs trouble ; and to ftart fuch difficulties, which he cannot afterwards fairly remove, will expofe both him¬ felf and his caufe. But as nothing gives an audience greater pleafure and fatisfadfion, than to have their fcruples fully anfwered as they rife in their thoughts ; fo on the contrary, be a difcourfe otherwife ever fo entertaining and agreeable, if there be any doubt left upon the minds of the hearers, it gives them a pain that continues with them till it be removed. St The figure hypobde or /abjection, is not much un- ORATORY. PartlH., like the former; and is, when feveral things areElocution|) mentioned that feem to make for the contrary fide, i" and each of them refuted in order. It confifts of three parts, when complete; a propofition, an enu¬ meration of particulars with their anfwers, and a conclufion. Thus, C'cero upon his return from ba- nifhment, vindicates his condudt in withdrawing fo quietly, and not oppofing the fa&ion that ejedled him. “ My departure (fays he) is objedfed to me, which charge I cannot anfwer without commending myfelf. For what muft; I fay ? That I fled from a confciouf- nefs of guilt ? But what is charged upon me as a crime, was fo far from being a fault, that it is the moft glo¬ rious adtion fince the memory of man, (he means his puniffiing the aflbciates of Cataline.) That I feared being called to an account by the people? That was never talked of; and if it had been done, I ffiould have come off with double honour. That 1 wanted the fupport of good and honeft men ? That is falfe. That I was afraid of death? That is a calumny. I muft therefore fay, what I would not, unlefs compel¬ led to it, that I withdrew to preferve the city.” When the objedlions are put by way of queftion, as in the example here given, they add a bri/knefs and poignan¬ cy to the figure. All the parts of it are not conftant- ly expreffed. For thus Cicero in his defence of Plan- cius introduces his adverfary objecting, and himfelf anfwering, “ The people judged ill, but they did judge; they Ihould not have done it, but they had a power; I cannot fubmit to it, but many very great and wife men have.” Both the propofition and con¬ clufion are here omitted. The next figure in order is anacoino/is, or communi¬ cation s by which the fpeaker deliberates either with the judges, the hearers, or the adverfary himfelf. Thus Cicero addreffes the judges in his accufation of Verres: “ Now I defire your opinion, what you think I ought to do. And I know your advice will be, though you do not declare it, what appears to me ne- ceffary to be done.” In another place we find him reafoning in this manner with the adverfe party : “ What could you have done in fuch a cafe, and at fuch a time; when to have fat ftill, or withdrawn, would have been cowardice? When the wickednefs and fury of Saturninus the tribune had called you into the Capi¬ tol ; and the confuls, to defend the fafety and liberty of your country ; whofe authority, whofe voice, which party would you have followed, and whofe command would you have chofen to obey?” This figure carries in it an air of modefty and condeftenfion, when the fpeaker feems unwilling to determine in his own caufe, but refers it to the opinion of others. It likewife fliews a perfuafioh of the equity of his caufe, that he can leave it to their arbitration; and ferves very much to conciliate their minds, while he joins them, as it were, with himfelf, and makes them of his party. And when the appeal is made to the adverfe party, it is of confiderable advantage, either to extort a con- feffion, or at lead to filence him. And therefore the facred writers fometimes very beautifully introduce God himfelf thus expoftulating with mankind; as the prophet Malachi, ^ Jon honoureth his father, and a fervant his majier. If then I be a father, ’where is mine honour? and if I be a majier, ’where is my fear? Another figure that comes under this head, is epi- I iJPart III. ORATORY. 5709 cut ion. epitrope or concejfion ; which grants one thing, to ob- tain another more advantageous. It is either real or feigned; and either the whole of a thing, or a part only, is granted. We fhall confider each of thefe fe- parately, and illuftrate them with proper examples. I Nothing more confounds an adverfary, than to grant him his whole argument; and at the fame time either to (hew that it is nothing to the purpofe, or to offer fomething elfe which may invalidate it. I allow, fays the claimant by will againfl the heir at law, that no body was more nearly related to the deceafed than you; that he was under fame obligations to you ; that you were in the army together: but what is all this to the will? And thus Cicero in his defence of Ligarius, who was acc-ufed by Tubero for having joined with Pompey in the civil war between him and Ctefar : “ You have, Tubero, what an accufer would mod 1 defire, the accufed perfon confefiing the charge ; but fo as to affirm, that he was of the fame party with you and your excellent father. Therefore own firft that it was a crime in yourfelf, before you charge it as fuch upon Ligarius.” Sometimes the orator gives up fome particular point that would well admit of a difpute, to gain fomething more confiderable, which he thinks cannot fairly be denied him. In the affair of Rofcius, where the proof depended upon circumflances, Cicero, who defended him, inquires what reafon could be alleged for his committing fo black a crime, as to kill his father. And after he has (hewn there was no probable reafon to be affigned for it, he adds, “ Well, iince you can offer no reafon, although this might be fufficient for me, yet I will recede from my right; and upon the affurance I have of his innocence, I will rant you in this caufe what I would not in another, do not therefore infift upon your telling me why he killed his father, but afk how he did it?” This ap¬ pearance of candour and ingenuity in fuch conceffions removes the fufpicion of art, and gives greater credit to what is denied. We have an example of a feigned or ironical conceffion, in Cicero’s defence of Flaccus; where, interceding for him on the account of his for¬ mer good fervices in the time of Cataline’s confpiracy, he fays in a way of irony, If fuch things are to be overlooked, “ let us appeafe the ghofts of Lentulus and Cethegus; let us recall thofe who are in exile; and let us be punifhed for our too great affe&ion and love for our country.” By this artful infinuation the orator, after he has ufed all his arguments to perfuade his hearers, does as it were fet them at li¬ berty, and leave them to their own ele&ion ; it being the nature of man to adhere more ftedfaft- ly to what is not violently impofed, but referred to their own free and deliberative choice. And to thefe feigned conceffions may be referred fuch ways of reafcning, by which 'the orator both juftifies a charge brought againft him upon the fuppofition ©f its being true, and alfo proves that the charge it- felf is falfe. Thus Cicero, in his defence of Milo, re- prefents the taking off Clodius, with which Milo was accufed, as a glorious a&ion ; after he has (hewn that Milo’s fervants did it without the knowledge of their mafter. Parabole or Jimilitude, illuflrates a thing by com¬ paring it with forae other, to which it bears a refem- blance. Similitudes are indeed generally but weak arguments, though often beautiful and fine ornaments. Elocution, And where the defign of them is not fo much to prove what is doubtful, as to fet things in a clear and agree¬ able light, they come properly under the notion of fi¬ gures. They are of two forts; fimple and compound. Thofe are called fimple, in which one thing only is likened or compared to another, in this manner : As fwallows appear in Jummer, but in winter retreat; fo falfefriendi foow tkemfelves in profperity, but allfly away when adverfity approaches. Compound fimilitudes are fuch, wherein one thing is likened or compared to fe- veral others ; as thus: What light is to the world, phy- fc to the fick, water to the thirfy, and ref to the weary; that is knowledge to the mind. The more exaft the a- greement is between the things thus compared, they give the greater beauty and grace to the figure. Antithefts or oppofition, by which things contrary 8j or different are compared, to render them more evi¬ dent. Thus Cicero fays, “ The Roman people hate private luxury, but love public grandeur.” This is a very florid figure; and fuited no lefs for amplifi¬ cation than proof. As in the following inftance of Cicero, where, fpeaking of Pompey, he fays, “ He waged more wars than others had read ; conquered more provinces than others had governed ; and hath been trained up from his youth to the art of war, not by the precepts of others, but by his own commands ; not by mifcarriages in the field, but by vi&ories; not by campaigns, but triumphs.” It is efteemed a beauty in this figure when any of the members are inverted, which fome czW antimetathefs. As where Cicero, oppo- fing the conduft of Verres when governor of Sicily, to that of Marcellus who took Syracufe the capital city of that ifland, fays, “ Compare this peace with that war, the arrival of this governor with the vidtory of that general, his profligate troops with the invincible army of the other, the luxury of the former with the temperance of the latter; you will fay, that Syracufe was founded by him who took it, and taken by him who held it when founded.” To this figure may alfo be referred oxymoron, or feeming contradiction; that is,, when the parts of a fentence difagree in found, but are confident in fenfe. As when Ovid fays of Althea, that foe was impioufy pious. And fo Cato ufed to- fay of Scipio Africanus, that “ he was never lefs at leifure, than when he was at leifure ; nor lefs alone,, than when alone :” By which he meant, as Cicero tells us, that “ Scipio was wont to think of bufinefs in his retirement, and in his folitude to converfe with himfelf.” This is a flrong and bold figure, which awakens the mind, and affords it an agreeable pleafure to find upon refledlion, that what at firfl feemed con- tradi&ory, is not only confident with good fenfe, but very beautiful. II. Thofe fuited to move the pafions. Which are 13 namely, epdnorthofs, paralepfs, parrhefa, aparithme- fs, exergafa, hypotypofs, aporia, pofopefs, erotefs, ec- phonefs, epiphonema, apofrophe, and profopeia. Epanorthofs, or correction, is a figure, by whLh the fpeaker either recalls or amends what he had lad faid. It is ufed'different ways. For fometimes one or more words are recalled by him, and others fub- joined in their room ; at other times, without recall¬ ing what has been faid, fomething elfe is fubdituted as more, fuitable. This is a very extenfive figure, and made.* 57io ORATORY. Part III. Elocution, made ufe of in addrefllng to different paflions. We lands, he makes ufe of this figure to reprefent the Elocmloit have an inftance of it in Terence’s Self-tormentor, pernicious effeds of fuch a law, particularly with re- where the old man, whofe extraordinary concern for fped to the lands in Italy. “ I do not complain the abfence of his fon gave occafion to the name of (fays he) of the diminution of our revenues, and the the play, thus bewails his condition to his neighbour, woful effeds of this lofs and damage. I omit what “ I have an only fon, Chremes. Alas! did I fay that may give every one occafion for a very grievous and I have? I had indeed; but it is now uncertain whe- juft complaint, that we could not preferve the prin- ther I have or not.” Here, to aggravate his misfor- cipal eftate of the public, the fineft pofl'tffion of the tune, he recalls a pleafing word, and fubftitutes ano- Roman people, the fund of our provifions, the granary ther more affeding in its place. And Cicero, in his of our wants, a revenue entrufted with the date; but defence of Milo, fpeaking to the judges concerning that we muft give up thofe lands to Rullus, which, Clodius, fays, “ Are you only ignorant, what laws, after the power of Sylla, and the largeffes of the if they may be called laws, and not rather torches and Gracchi, are yet left us. I do not fay, this is now plagues of the ftate, he was about to impofe and force the only revenue of the ftate, which continues when ire in hia nf Planrina It? fa vs - others rpafp. is an nrnampnf in nparp. failq na nnt in 57 upon us ?” Again, in his defence of Plancius he fays, others ceafe, is an ornament in peace, fails us not in “ What greater blow could thofe judges, if they are war, fupports the army, and does not fear an enemy, to be called judges, and not parricides of their coun- I pafs over all thefe things, and referve them for my try, have given to the ftate, than when they banilhed difcourfe to the people,, and only fpeak at prefent of him, who, when prxtor, freed the republic from a the danger of our peace and liberties.” His view neighbouring war, and when conful, from a civil one ?” here was to raife the indignation of the fenate againft He is fpeaking there of Opimius. But in commend- Rullus, and excite them to oppofe the law. There is ing the moderation of Lucius Mummius, who did not a beautiful inftance of this figure in St Paul’s epiftle enrich himlelf, but his country, by demolilhing the to Philemon, where, after he has earnei'tly intreated wealthy city of Corinth, he thus recalls his whole ex- him to receive again Onefimus his fervant, who had ^preffion, and by giving it a new turn heightens the run from him, and promifed that if he had wronged compliment he defigned him : “ He chofe rather him, or owed him any thing, he would repay it, he (fays he) to adorn Italy, than his own houfe; though adds, That I may not fay, you owe even yourfelf to me, by adorning Italy, his houfe feems to have received Nothing could be a ftronger motive to foften his dif- the greateft ornament.” And fometimes the correc- pleafure againft his fervant, from a fenfe of gratitude tion is made by fubftituting fomething contrary to to the apoftle. Hermogenes has obferved, that the what had been faid before ; as in the following paf- defign of this figure is to poffefs the minds of the au- fage of Cicero : “ Csefar, (meaning Auguftus) though dience w’ith more than the words exprefs, and that it but a youth, by an incredible and furprifing refolu- is principally made ufe of on three occafiops: either tion and courage, when Antony was moft enraged, when things are fmall, but yet neceffary to be men- and we dreaded his cruel and pernicious return from tioned ; or well known, and need not be enlarged Brundufium, at a tipie when we neither aflced, nor ex- on; or ungrateful, and therefore fhould.be intro- petfted, nor defired it, (becaufe it was thought impof- duced with caution, and not fet in too ftrong a fible), raifed a very powerful army of invincible ve- light. , terans; to effeft which, he threw away his whole eftate: The next figure abovementioned was Parrhefa, or Tho' I have ufed an improper word ; for he did not reprehenfion : Not that whenever a perfon admonifhes throw it away, but employed it for the fafety of the or reproves another, it is to be efteemed a figure; but government.” At other times, as has been faid, the when it is done with art and addrefs, and in fuch cir- corre&ion is made by adding a more fuitable word, cumftances as render it difficult not to difpleafe. The without any repetition of the former. Thus Cicero, The orator therefore fometimes prepares his hearers after he has inveighed againft the crimes of Verres, for this by commending them firft, urging the ne- breaks out into this pathetic exclamation ; 0 the cle- ceffity of it, reprsfenting his great concern f^r them mency, or rather wonder ful andftngular patience, of the as his motive, or joining himfelf with them. Thus Roman people! He did not think the word clemency Cicero charges the fenate with the death of Servius ftrong enough, and therefore adds patience, as better Sulpicius, for fending him to Mark Antony under a anfwering his defign. The hidden and unexpe&ed very ill ftate of health. And his defign in it was to turn of this figure gives a furprize to the mind, and bring them more readily into a motion he was about by that means renders it the more pathetic. to make, that both a ftatue and a fepulchral monu- Paralepfis, or omiffion, is another of thefe figures, ment might be eredled to his memory at the public when the fpeaker pretends to omit, or pafs by, what expence. “ You (fays he), it is a-very fevere ex- at the fame time he declares. It is ufed either in preffion, but Icannot help faying it; you, I fay, have de- praife or difpraife. Thus Cicero, in his defence of prived Servius Sulpicius of his life. It was not from Sextius, introduces his charaQer in this manner, with cruelty indeed, (for what is there with which this a defign to recommend him to the favour of the court: aficmbiy is lefs chargeable?) but when his di^emper “ I might fay many things of his liberality, kindnefs pleaded his excufe more than his words, from the to his domeftics, his command in the army, and mo- hopes you conceived, that there was nothing which deration during his office in the province: but the ho- his authority and wifdom might not be able to effedf, nour of the ftate prefents itfeif to my view; and calling you vehemently oppofed his excufe, and obliged him, me to it, advifes me to omit thefe leffer matters.” who always had the greateft regard for your com- But in bis oration, to tlje fenate againft Rullus the mands, to recede from his refolution.” Sometimes, tribune, who had propofed a law to fell the public indeed, the orator affumes an air of reproof, with a locution view only to pafs a compliment with a better grace. "" ' As Cicero in his addrefs to Casfar, when he fays, “ I hear that excellent and wife faying from you with concern. That you have lived long enough, either for the purpofes of nature, or glory: for nature perhaps, if you think fo; and, if you pleafe, for glory; but, what is principally to be regarded, not for your coun¬ try.” It adds both a beauty and force to this figure, when it is expreffed in a way of comparifon. As in the following inftance of Cicero: “ But fince my dif- courfe leads me to this, confider how you ought to be affedfed for the dignity and glory of your empire. Your anceftors often engaged in war to redrefs the injuries of their merchants or failors: how ought you then to refent it, that fo many thoufand Roman ci¬ tizens were murdered by one meflage, and at one time? Your forefathers deftroyed Corinth, the principal city in Greece, for the haughty treatment of their am- bafiadors ; and will you fuller that king to go un- punilhed who has put to death a Roman legate, of confular dignity, in the moft ignominious as well as moll cruel manner ? See, left, as it was their honour to leave you the glory of fo great an empire, it Ihould prove your difgrace not to be able to maintain and defend what you have received from them.” By this figure an addrefs is made to the more tender paffions, jnodefty, lhatne, and emulation, the attendants of an ingenuous temper, which is fooneft touched, and moft; affe&ed, by a juft reproof. g Another of thefe pathetic figures is Aparithmejist I or enumeration, when that which might beexprelfed in general by a few words, is branched out into feveral particulars, to enlarge the idea, and render it the more affe&ing. Cicero in pleading for the Manilian law, where his defign is to conciliate the love and elleem of the people to Pompey, thus enlarges upon his charafter: “ Now, what language can equal the virtue of Cneius Pompey ? What can be faid either worthy of him, of new to you, or which every one has not heard? For thofe are not the only virtues of a general which are commonly thought fo; labour in affairs, courage in dangers, induftry in afting, dif- patch in performing, defign in contriving; which are greater in him than in all other generals we have ever feen or heard of.” And fo likewife, when he endea¬ vours to difpoffefs Pompey of the apprehenfion that ^ Milo defigned to affaffinate him: “ if (fays he) you fear Milo; if you imagine that either formerly, or at prefent, any ill defign has been formed by him againft your life; if the foldiers ratfed through Italy, (as fome of your officers give out), if thefe arms, if thefe cohorts in the Capitol, if the Gentries, if the watch, if the guards which defend your perfon and houfe, are armed to prevent any attempt of Milo, and all of them appointed, prepared, and ftationed on his account; he muft be thought a perfon of great power, and incre¬ dible refolution, above the reach and capacity of a fingle man, that the moft confumihate general, and the whole republic are in arms againft him only. But who does not perceive, that all the difordered and ^ finking parts of the ftate are committed to you, to redlify and fupport them by thefe forces ?” This might have been faid in a few words, that fuel) vaft preparations could never be intended for fo low a purpofe. But the orator’s view was to expofe that Von. VIII. i groundlefs report, and ffiame it out of countenance. Elocution. And foon after he endeavours to raife compaffion for”" Milo under thofe prejudices, by the fame figure: “ See how various and changeable is the ftate of human life, how unfteady and voluble is fortune, what infidelity in friends, what difguifes fuited to the times, what flights, what fears, even of the neareft acquaintance, at the approach of dangers.” Had no addrefs to the paffions been defigned here, fewer of thefe reflexions might have been fufficient. The ufe of this figure in amplification is very evident from the nature of it, which confifts in unfolding of things, and by that means enlarging the conception of them. Exergajia, or expojition, has an affinity with the 9© former figure: but it differs from it in this, that it confifts of feveral equivalent expreffions, or nearly fuch, in order to reprefent the fame thing in a ftronger manner; whereas the other enlarges the idea by an enumeration of different particulars. So that this figure has a near relation to fynonymia, of which we have treated before under Verbal figures. We have an inftance of it in Cicero’s defence of Sextius, where he fays, “ Thofe who at any time have incited the populace to fedition, or blinded the minds of the ig¬ norant by corruption, or traduced brave and excellent men, and fuch as deferved well of the public, have with us always been efteemed vain, bold, bad, and per¬ nicious citizens. But thofe who repreffed the at¬ tempts and endeavours of fuch as, by their autho¬ rity, integrity, co'nftancy, refolution, and prudence, withftood their infolence, have been always accounted men of folidity, the chiefs, the leaders, and fupporters of our dignity and government.” Nothing more is intended by this paffage, but to fet the oppofite cha- radlers of fa&ious perfons and true patriots in the ftrongeft light, with a view to recommend the one, and create a juft hatred and deteftation of the other. So elfewhere he reprefents the juftice of felf-defence in no lefs different terms: “ If reafon (fays he) pre- feribes this to the learned, and neceffity to barbarians, cuftom to nations, and nature itfelf to brutes, always to ward off all manner of violence, by all poffible ways, from their body, from their head, from their life; you cannot judge this to- be a criminal and wicked action, without judging at the fame time that all perfons who fall among robbers and affaffins muft either perifh by their Jweapons, or your fentence.”—• He is addreffing here to the judges in favour_of Milo. The warmth and vehemence of the fpeaker often runs him into this figure, when he is affefted with his fub- je£l, and thinks no words, no expreffions, forcible enough to convey his fentiments ; and therefore re¬ peats one after another, as his fancy fuggelts them. This ftgw of expreffion, under the conduct of a good judgment, is often.attended with advantage; as it warms the hearers, and impreffes their minds, excites their paffions, and helps them to fee things in a ftronger li8ht- Hypotypojis, or imagery, is a defeription of things painted in fuch ftrong and bright colours, as may help the imagination of the hearers to conceive of them rather as prefent to their view, than deferibed in words. It is peculiarly fuited for drawing chara&ers; and often affords the fined ornaments in poetry and hiftory, as well as oratory. Nor is it lefs moving, 32 G but 5712 O R A T Elocution, but fuited to finite different paflions, according to the nature of the fubjeft, and artful management of the fpeaker. Cicero haa thus drawn the pi&ure of Cati¬ line, confifting of an unaccountable mixture of con¬ trary qualities. “ He had (fays he) the appearance of the greatelt virtues! he made ufe of many ill men to carry on his defigns, and pretended to be in the intereft of the bed men; he had a very engaging be- - haviour, and did not want induftry nor application; he gave into the greateft loofenefs, but was a good foldier. Nor do I believe there was ever the like monfter in the world, made of fuch janing and re¬ pugnant qualities and inclinations. Who at one time was more acceptable to the beft men, and who more intimate with the word? Who was once a better pa¬ triot, and who a greater enemy to this date? Who more devoted to pleafures, who more patient in la¬ bours? Who more rapacious, and yet more profufe? He fuited himfelf to the humours of all he converfed with: was ferious with the referved, and pleafant with the joeofe; grave with the aged, and facetious with the young ; bold with the daring, and extravagant with the profligate.”—Such a charafter of a man, when accompanied with power and intered, mud render him no lefs the objeft of fear, than detedation; which was the defign of Cicero in this defcription. And elfewhere, in order to prevail with the fenate to dire&the execution of thofe confpirators with Catiline who were then in prifon, he paints the mod difmal fcene of that horrid defign in the dronged colours. “ Muhinks (fays he) I fee this city, the light of the world, and citadel of all nations, fuddenly falling into one fire; I perceive heaps of miferable citizens un¬ buried in their ruined country; the countenance and fury of Cethegus raging in your flaughter, prefents itfelf to my view.” This figure is very ferviceable in amplification, as we have formerly fhewn in treating upon that fubjedl. But no fmall judgment is required in the management of defcriptions. L.effer circum- dances flionld either be wholly omitted, or but llightly touched; and thofe which are more material drawn in their due proportion. Nature is as much the rule of the orator as of the painter, and what they both pro- pofe to imitate. And therefore, let a thought be ever lb pleafing and beautiful in itfelf, it mud not be in¬ troduced when foreign to the purpofe, or out of its place; any more than a painter fhould attempt to alter nature, when he propofes to copy it. This figure re¬ quires likewife a vigorous and lively genius. For the images in defcription can rife no higher than the con¬ ception of the fpeaker, fince the idea mud fird be formed in his own mind before he can convey it to others; and agreeably to the clearnefs with which he conceives it himfelf, he will be able to exprefs it in words. 92 jfporia, or doubt, expreffes the debate of the mind with itfelf upon a preffing difficulty. A perfon in fuch a date is apt to hefitate, or dart feveral things fuccefiively, without coming to any fixed refolution. The uneafinefs arifing from fuch a diforder of thought is naturally very moving. Of this kind is that of , Cicero for Cluentius, when he fays, “ I know not which way to turn myfelf. Shall I deny the fcandal thrown upon him of bribing the judges? Can I fay the people were not told of it ? that it was cot talked 93 O R Y. Partlll. of in the court? mentioned in the fenate? Can I re- Elocution, move an opinion fo deeply and long rooted in the ~ minds of men ? It is not in my power. You, judges, mud fupport his innocence, and refeue him from this calamity.” Orators fometimes choofe to begin their difeourfe wu'th this figure. A diffidence of mind at fird is not unbecoming, but graceful. It carries in it an air of modedy, and tends very much to conciliate the affe&ions of the hearers. Livy gives us a very elegant example of this, in a fpeech of Scipio Afri- canus to his foldiers, when, calling them together after a fedition, he thus befpeaks them: “ I never thought I fhould have been at a lofs, in what manner to ad- drefs my army. Not that I have applied myfelf more to words, than things; but becaufe I have been ac- cudomed to the genius of foldiers, having been trained up in the camp almoft from my childhood. But I am in doubt what or how to fpeak to you, not knowing what name to give you. Shall I call you citizens, who have revolted from your country? Soldiers, who have difowned the authority of your general, and broke your military oath? Enemies? I perceive the mien, the afpeft, and habit of citizens; but difeern the a&ions, words, defigns, and difpofitions of enemies.” Sometimes a paffion has that effedl, not fo much to render a perfon doubtful what to fay, as to dop him in the midd of a fentence, and prevent his expreffing the whole of what he defigned; and then it is called Apoftopejis, or concealment. It denotes different paf- fions; as anger, which, by reafon of its heat and vehe¬ mence, caufes perfons to break off abruptly in their difeourfe. So the old man in Terence, when he was jealous that his fervant obdrudfed his defigns, ufes this imperfedt, but threatening expreffion ; Whom, if / find." And Neptune, when deferibed by Virgil as very angry that the winds fhould prefume to didurb the fea without his permiffion, after he has called them to him to know the reafon of it, threatens them in this abrupt manner: “ Whom I- hut firft I’ll lay the ftorm.” But Cicero, in writing to Atticus, applies it to ex¬ prefs grief, where he fays, “ I know nothing of Pom- pey, and believe he mud be taken, if he is not got on fhipboard. O incredible fwiftnefs ! But of our friend.— Though I cannot accufe him without grief, for whom I am in fo much concern and trouble.” And in a letter to Caffius he ufes it to exprefs fear, when be fays to him, “ Brutus could fcarce fupport himfelf at Mutina; if he is fafe, we have carried the day. But if—heaven avert the omen 1 all mud have recourfe to you.” His meaning is, “ If Brutus fhould be de¬ feated.” The next figure is erotefis, or interrogation. But every interrogation or quedion is not figurative. When we inquire about a thing that is doubtful, in order to be informed, this is no figure, but the natural form of fuch expreffions. As if I aflc a perfon, Where he is going? or What he is doing ? But then it becomes fi¬ gurative when the fame thing may be expreffed in a diredl manner; but the putting it by way of que- ftion gives it a much greater life and fpirit. As when Cicero fays, “ Catiline, how long will you abufe our patience ? do not you perceive your defigns are difeo- vered ?” He might indeed have faid, abufe our patience a long while. Ton tnufi be fenjible your defigns 94 Part III. ORA Elocution, are difcovered. But It Is eafy to perceive how much this latter way of expreffion falls fhort of the force and vehemence of the former. And fo when Medea fays, I could fave ; and do you aft) if I can defray ? Had /he faid, I could fave, and I can defray, the fentence had been flat, and very unfit to exprefs the rage and fury in which the poet there reprefents her. This fi¬ gure is fuited to exprefs molt pafiions and emotions of the mind, as anger, difdaitf, fear, defire, and others. It ferves alfo to prefs and bear down an ad- verfary. Cicero frequently makes this nfe of it. As in his defence of Plancius: “ I will make you this of¬ fer (fays he) choofe any tribe you pleafe, and /hew, as you ought, by whom it was bribed ; and if you cannot, as I believe you will not undertake it, I will prove how he gained it. Is this a fair contelt ? Will you engage on this loot ? I cannot give you fairer play. Why are you filent ? Why do you difiemble ? Why do you hefitate ? I infill upon it, urge you to it, prefs it, require, and even demand it of you.” Such a way of pulhingan antagonift fhews the fpeaker has great confidence in his caufe; otherwife he would ne¬ ver lay himfelf fo open, if he was not affured the other party had nothing to reply. This figure likewife di- verfifies a difcourfe, and gives it a beautiful variety, by altering the form of exprellion; provided it be nei¬ ther too frequent, nor continued too long at once. And befides the warmth and eager manner in which it is exprefled, enlivens the hearers, and quickens their attention. Ecphoneftf, or exclamation, is a vehement exten- fion. of the voice, occafioned by a commotion of mind, naturally venting itfelf by this figure, which is ufed by Cicero to exprefs a variety of pafiions. It often denotes refentment or indignation. Thus, after his return from banifhment, reflecting on thofe who had occafioned it, he breaks but into this moving ex¬ clamation : “ O mournful day to the fenate, and all good men, calamitous to the flate, afflictive to me and my family, but glorious in the view of pofterity 1” Hisdefign was to excite an odium againll the authors of his exile, when recalled in fo honourable a manner. And again in his defence of Caslius : “ O the great force of truth; which eafily fupports itfelf againlt the wit, craft, fubtilty, and artful defigns of men 1” He had been juft /hewing the abfurdity of the charge againft Caelius, and now endeavours to expofe his ac- cufers to the indignation of the court. At other times it is ufed to exprefs difdain or contempt. As when fpeaking of Pompey’s houfe, which was bought by Mark Anthony, he fays: “ O confum- mate impudence! dare you go within that houfe! dare you enter that venerable threlhold, and /how your au¬ dacious countenance to the tutelar deities, which re- lide there ?” Nor is it lefs fuited to indicate grief, as when he fays of Milo: “ O that happy country, which /hall receive this man ! ungrateful this, if it bani/h him ! miferable, if it lofe him !” And foraetimes it ferves to exprefs admiration; as when, in compliment to Caefar, he fays, “ O admirable clemency i worthy of the greateft praife, the higheft encomiums, and moft lafting monuments!” It has its ufe alfo in ridi¬ cule and irony. As in his oration for Balbus, where he derides his accufer, by faying, “ O excellent in¬ terpreter of the law! mafter of antiquity i corrector TORY. 57I3 and amender of our conftitution !” The facred writers Elocution, fometimes ufe it by way of intreaty or vvi/h. As the ~ royal Pfalmift : “ O that I had the wings of a dove, that I might flee away, and be at reft 1” And at other times in triumph and exultation, as in that of St Paul : “ O death, where is thy (ling! O grave, where is thy victory!” It is frequently joined with the preceding fi. gure, interrogation; as appears in fome of the inftan- ceshere brought from Cicero. And it generally fol¬ lows the reprefentation of the thing which occafions it. Though fometimes it is made ufe of to introduce it, and then it ferves to prepare the mind by exciting its attention. Thus Cicero, in his defence of Caelius, to render the character of Clodia more odious, at whofe inftigation he was accufed, infinuates that fhe had be¬ fore poifoned her hufband ; and to heighten the bar¬ barity of the faCt,and make it appear the more/hock¬ ing, he Introduces the account of it, with this mo¬ ving exclammation : “ O heavens, why do you fome¬ times wink at the greateft crimes of mankind, or de¬ lay the puni/hment of them to futurity !” Epiphonema, or acclamation,. has a great affinity with the former figure. And it isfo called, when the fpeaker, at the conclufion of his argument, makes fome lively and juft remark upon what he has been faying, to give it the greater force, and render it the more affeCling to his hearers. It is not fo vehement and impetuous as exclamation, being ufually expre/five of the milder and more gentle pafiions. And the reflec¬ tion ought not only to contain fome plain and obvious truth, but likewife to arife naturally from the difcourfe which occafioned it, otherwife it lofes its end. When Cicero has /hewn, that recourfe is never to be had to force and violence, but in cafes of the utmoft necefii- ty, he concludes with the following remark : “ Thus to think, is prudence; to ad, fortitude; both to think and aCt; perfeCt and confummate virtue.” And elfe- where, after he has defcribed a fingular inft'ance of cruelty and breach of friendfhip : “ Hence (fays he) we may learn, that no duties are fo facred and folerr.n, which covetoufnefs will not violate.” This figure is frequently exprefled in a way of admiration. As when Cicero has obferved, that all men are defirous to live to an advanced age, but uneafy tinder it when at¬ tained, he makes this juft refletftion upon fitch a con- duift: “ So great is their inconftancy, folly, and per- verfenefs!” The next figure in order is apofrophe, or addreft, Q_ when the fpeaker breaks off from the feries of his dif- courfe, and addreffes himfelf to fome particular perfon prefent or abfent, living or dead ; or to inanimate na¬ ture, as endowed with fenfe and reafon. By this means he has an opportunity of faying many things with greater freedom than perhaps would be confident with decency if immediately dire&ed to the perfons themfelves. He can admoni/h, chide, or cenfure, with¬ out giving offence. Nor is there any pafiion, but may be very advantageoufly exprtffed by this figure. When an orator has been fpeaking of any particular perfon, on a fudden to turn upon him, and apply the difcourfe to that perfon himfelf, is very moving; it is like at¬ tacking an adverfary by furprize, when he is off his guard, and where he lead expefts it. Thus Ci¬ cero : “ I defire, fenators, to be merciful, but not to appear negligent in fo great dangers of theftate; tho’ 32 G 2 at 57*4 O R A T Elocution, at prefent I cannot bnt condemn myfelf of remiffnefs. There is a camp formed in Italy, at the entrance of Etruria, againft the date; our enemies increafe daily; but we fee the commander of the camp, and general of the enemies, within our walls, in the very fenate, contriving fome inteftine ruin to the date. If now, Catiline, I fiiould order you to be feized and put to death, I have reafon to fear, that all good men would rather think I had deferred it too long, than charge me with cruelty. But I am prevailed with for a certain reafon not to do that yet, which ought to have been done laiig fince.” This fudden turn of the difcourfe to Catiline himfelf, and the addrefs to him in that un- expefted manner, mud have touched him very fenfibly. So in his defence of Milo, expreffing his concern if he diould not fucceed in it, he fays: “ And how fliall I anfwer it to you, my brother Quintus, the partner of my misfortunes, who art now abfent.” And elfe- where addrefling to the foldiers of the Martian legion, who had been killed in an engagement with Mark An¬ thony, he thus befpeaks them: “ O happy death, which due to nature, was paid to your country ! I may efteem you truly born for your country, who likewife received your name from Mars; fo that the fame deity feems to have produced this city for the world, and you for this city.” And in his oration for Balbus he thus calls upon dumb nature to witnefs to Pompey’s virtues: I invoke you, mute regions; you, mod di- ftant countries; you feas, havens, iflands, and ftiores. For what coad, what land, what place is there, in which the marks of his courage, humanity, wifdom, and prudence, are not extant?” An appeal to heaven, or any part of inanimate nature, has fomething very fublime and folemn in it, which we often meet with in facred writ. So the divine prophet: “ Hear, O hea¬ vens! and give ear, O earth! for the Lord hath fpoken.” And in like manner, the prophet Jeremy: “ Be ado- nilhed, O ye heavens, at this.” 58 Profopoptea, or the fi£lion of a perfon: by which, ei¬ ther an abfent perfon is introduced fpeaking; or one who is dead, as if he was alive and prefent; or fpeech is attributed to fome inanimate being. There is no figure, perhaps, which ferves more or better purpofes to an orator, than this. For by this means he is en¬ abled to call in all nature to his aflidance, and can affign to every thing fuch parts as he thinks conve¬ nient. There is fcarce any thing fit to be faid, but may be introduced this way. When he thinks his own ehara&er is not of fufficient weight to affeft his audience in the manner he defires, he fubditutes a per¬ fon of greater authority than himfelf to engage their attention. When he has fevere things to fay, and which may give offence as coming from himfelf; he avoids this, by putting them into the mouth of fome other perfon from whom they will be better taken ; or makes inanimate nature bring a charge, or exprefs a refentment, to render it the more affedting. And by the fame method he fometimes choofes to fecure him¬ felf from a fufpicion of flattery, in carrying a com¬ pliment too high. We meet with feveral very beautiful indances of this figure in Cicero ; but an example of each fort may here fuffice, beginning with that of an abfent perfon, from his defence of Milo, whom he thus introduces as fpeaking to the citizens of ^Rome: “ Should he, holding the bloody fword, cry out, At- ' O R Y. Partin. tend, I pray, hearken, O citizens, I have killed Pu- Elocution, blius Clodius ; by this fword. and by this right hand, I have kept off his rage from your necks, which no laws, no courts of judicature, could reftrain ; it is by my means, thatjudice, equity, laws, liberty, (hame, and, modefty, remain in the city. Is it to be feared how the city would bear this a&ion ? Is there any one now, who would not approve and commend it.” And in his oration for Balbus, he introduces Marius, who was then dead, to plead in bis defence : “ Can. Balbus (fays he) be condemned, without condemning Marius for a like faft ? Let him be prefent a little to your thoughts, fince he cannot be fo in perfon ; that you may view him in your minds, though you cannot with your eyes. Let him tell you, he was not unac¬ quainted with leagues, void of examples, or ignorant of war.” And again, in his firft inveftive againft Ca¬ tiline, he reprefents his country as thus expoftulating with himfelf, and upbraiding him for fuffering fuch a criminal as Catiline to live. “ Should my country (fays he), which is much dearer to me than my life, fhould all Italy, all the ftate, thus addrefs me, Mark Tully, what do you do ? Do you fuffer him, whom you have found to be an enemy, who you fee is to be at the head of the war, whom you perceive your ene¬ mies wait for in their camp as their general, who has been the contriver of this wickednefs, the chief of the confpiracy, the exciter of flaves and profligate citizens, to leave the city, which is rather to bring him in, than let him out ? Will not you order him to be imprifon- ed, condemned, and executed ? What prevents you ? The cuftom of ouranceftors ? But private„perfons have often punifhed pernicious citizens in this ftate. The laws relating to the punifhment of Roman citizens ? But traitors never had the rights of citizens. Do you fear the cenfure of pofterity ? Truly you make a very handfome return to the people of Rome, who have ad¬ vanced you from an obfcure condition fo early to the higheft dignity ; if you negleft their fafety to avoid envy, or from the apprehenfion of any danger. And if you fear cenfure ; which is moft to be dreaded, that which may arife from juftice and fortitude, or from cowardice and treachery ? When Italy fhallbe wafted by a war, cities plundered, and houfes burnt, do you think then to efcape the fevereft cenfure.” In the management of this figure, care fhould be taken, that what is faid be always confiftent with the chara&er in¬ troduced, in which both the force and beauty of it confift. In treating upon figures, we have hitherto confider- ed them feparately; but it may not be amifs to ob- ferve, that fome expreflions confift of a complication of them, and may come under the denomination of fe¬ veral figures, as well verbal as thofe of fentences, differently confidered. Thus when Cicero fays: “ What, Tubero, did your drawn fword do in the Pharfalian battle ? at whofe fide was its point direc¬ ted ? what was the intention of your arms ?” As he fpeaks to Tubero, it is an apoftrophe ; as the expref- fions have much the fame import, and are defigned to heighten and aggravate the fa£t, it is exergafa ; and as they are put by queftion, it is interrogation. So likewife in his fecond Philippic, where he fays, “ What can I think ? that I am contemned ? I fee no¬ thing in my life, intereft, adions, or abilities, as mo- * * derate Part IIL ORA ocutiQn- derate as they are, which Anthony can defpife. Did he think he could eafily leffen me in the fenate ? But they, who have commended many famous citizens for their good government of the ftate, never thanked any but me for preferving it. Would he contend with me for eloquence ? This would be a favour indeed. For what could be a larger and more copious fubjed, than for me to fpeak for myfelf againft Anthony ? His de- fign was really this: he thought he could nor convince his aflbciates, that he was truly an enemy to his coun¬ try, unlefs he was fo firft to me.” There are three fi¬ gures in this pafTage ; doubt, interrogation, and jub- jeftion. And again, when he introduces Sicily thus addrefiirrg to Verres in a way of complaint: “ What¬ ever gold, whatever filver, whatever ornaments in my cities, dwellings, temples, whatever right of any kind I poffefled by the favour of the fenate and people of Rome ; you, Verres, have plundered and taken from me.” Here is a profopopeia, joined with the verbal fi¬ gure anaphora, as feveral members of the fentence be¬ gin with the fame word. The like inftances of complex figures frequently occur, and therefore we need not multiply examples of them here. PARTICULAR ELOCUTION, Or that part of Elocution which confiders the feveral Properties and Ornaments of Language, as they are made ufe of to form different forts of Style. Chap. IV. Of Style, and its different CharaSlers. 99 The word Jlyle, properly fignifies the inftrument which the ancients ufed in writing. Tor as they com¬ monly wrote upon thin boards covered over with wax, and fometimes upon the barks of trees, they made ufe of a long inftrument like a bodkin, pointed at one end, with which they cut their letters; and broad at the other, to eraze any thing they chofe to alter. And this the Latins called f ilus. But tho’ this be the firft fenfe of the word, yet afterwards it came to denote the manner of expreffion. In which fenfe we likewife ufe it, by the fame kind of trope that we call any one’s writing his hand. But as to the rea- fons which occafiona variety of ftyle, they are princi¬ pally thefe. Since both fpeech and writing are only fenfible ex- prefiions of our thoughts, by which we communicate them to others; as all men think more or lefs diffe¬ rently, fo confequently they in fome meafure differ in their ftyle. No two perfons, who were to write up¬ on one fubjefl, would make ufe of all the fame words. And were this poflible, yet they would as certainly differ in their order and connexion, as two painters, who ufed the fame colours in painting the fame pic¬ ture, would neceffai-ily vary their mixtures and dif- pofition of them, in the feveral gradations of lights and (hades. As every painter therefore has fomething peculiar in his manner, fo has every writer in his ftyle. It is from thefe internal charafters, in a good meafure, that critics undertake to difcover the true authors of anonymous writings ; and to (hew that others are fpu- rioue, and not the genuine produ&ions of thofe whofe names they bear; as they judge of the age of fuch TORY. 57J5 writings from the words and manner of exprefiion Elocution- which have been in ufe at different times. And we may often obferve in perfons a fondnefs for fome par¬ ticular words or phrafes; and a peculiarity in the turn or connexion of their fentences, or in their tranfitions from one thing to another; by which their ftyle may be known, even when they defign to conceal it. For thefe things, thro’ cuftom and habit, will fometimes drop from them, notwithdanding the greateft caution to prevent it. There is likewife very often a confiderable difference in the ftyle of the fame perfon, in feveral parts of his life. Young perfons, whofe invention is quick and lively, commonly run into a pompous and luxuriant ftyle. Their fancy reprefents the images of things to their mind in a gay and fpritely manner, cloathed with a variety of cifcumftances; and while they en¬ deavour to fet off each of thefe in the brighteft and mod glittering colours, this renders their ftyle ver- bofe and florid, but weakens the force and (Length of it. And therefore, as their imagination gradually cools, and comes under the conduct of a more mature judgment, they find it proper to cut off many fuper- fluities ; fo that by omitting unneceffary words and cir- cumftances, and by a clofer connexion of things placed in a (Longer light, if their ftyle becomes lefs (welling and pompous, it is, however, more correft and nervous. But as old age finks the powers of the mind, chills the imagination, and weakens the judge¬ ment ; the ftyle, too, in proportion ufualiy grows dry and languid. Critics have obferved fomething of this difference in the writings even of Cicero himfelf. To be mafter of a good ftyle, therefore, it feems neceffary that a perlbn ftiould be endued with a vigorous mind and lively fancy, a (Long memory, and a good judge¬ ment. It is by the imagination that the mind con¬ ceives the images of things. If the imprdfions of thofe images be clear and diftind, the ftyle will be fo too ; fince language is nothing but a copy of thofe images firft conceived by the mind. But if the images are faint and imperfect, the ftyle will accordingly be flat and languH. This is evident from the difference between fuch obje&s as are reprefented to our fight, and things of which we have only reader heard. For as the former generally make a deeper impreflion up¬ on our minds, fo we can deferibe them in a m6re (Long and lively manner. And we commonly find, that according as perfons are affe&ed themfelves when they fpeak, they are able to affeft others with what they fay. Now perfons are more or lefs affe&ed with things in proportion to the impreffions which the images of thofe things make upon the mind. For the fame reafon alfo, if the imagination be dull, and in- difpofed to receive the ideas of things, the ftyle will be ftiff and heavy ; or if the images are irregular and difordered, the ftyle will likewife be perplexed and confufed. When things lie ftraight (as we fay) in the mind, we exprefs them with eafe, and in their jult connexion and dependence ; but when they are warpt and crooked, we deliver them with pain and difficulty, as well as diforder. A good fancy fhould likewife be accompanied with a happy memory. This helps us to retain the names of thofe things the ideas whereof are prefented to the mind by the imagination, together' 57*6 Elocution. tliey are apt to hurry perfons into many inconveniences. Such are generally great talkers, but far from good orators. Frefti images continually crowd in upon them, fader than the tongue can well exprefs them. This runs them into long and tedious difcourfes, abounding with words, but empty of fenfe. Many ORATORY. Part II together with proper and fuitable phrafes to exprefs prefently difcovered. Hence it is often found, that Elocution|» them in their feveral ,conneftions and relations to each difcourfes, which were thought very fine when heard, r“ other. When the images of things offer themfelves to appear to have much lefs beauty, as well as drength, the mind, unlefs the names of thenrprefent themfelves when they come to be read. And therefore it is not at the fame time, we are at a lofs to exprefs them, or without reafon, that Cicero recommends to all thofe at lead are in danger of doing it by wrong and improper who are candidates for eloquence, and defirous to be- terms. Befides, variety is necedary in difcourfe to come maders of a good dyle, to write much. This render it agreeable ; and therefore, without a large affords them an opportunity to diged their thoughts, furniture of words and phrafes, the dyle will neceffari- weigh their words and expreffions, and give every ly become inlipid and jejune, by the frequent return thing its proper force and evidence; as likewife, by of the fame terms and manner of expreflion. But to reviewing a difcourfe when compofed, to corredl its both thefe a folid judgment is highly requifite to form errors, or fupply its defe&s ; till by practice they a jud and accurate dyle.

The eadern nations had a lofty and majedic way of fpeaking. Their words are full and fonorous, their expreflions drong and forcible, and warmed with the mod lively and moving figures. w . _ This is very evident from the Jewifh writings in the impertinencies, if not improprieties, neceffarily mix Old Tedament, in which we find a mod agreeable themfelves with what they fay ; and they are fre- mixture of fimplicity and dignity.

So that, in a word, the foundation of a good Again, people of different nations vary in their ftyle is chiefly good fenfe. Where thefe qualities all cuftoms and manners, which occafions a diverfity in meet in a confiderable degree, fuch perfons have the their ftyle. This was very remarkable in the Attics, happinefs to excell, either in fpeaking or writing. Afiatics, and Rhodians, and is often taken notice of But this is not generally the cafe. Many perfons of by ancient writers. The Athenians, while they con- a vigorous and fpritely imagination, have but a weak tioued a free ftate, were an aflive, indultrious, and judgment; and others much more judicious can think frugal people ; very polite indeed, and cultivated arts but (lowly. And it is this, in a great meafure, which and fciences beyond any other nation : but as they makes the difference between fpeaking and writing had powerful enemies, and were exceeding jealous of veil, as one or the other of thefe qualities is predo- their liberties, this preferved them from wantonnefs minant.

The Afiatics, on the other hand, upon due premeditation, to difeern farther into the were more gay, and loofe in their manners, devoted fubjed, but cannot command his thoughts with the to luxury and pleafure; and accordingly they affedted fame eafe and freedom. And this latter would have a florid and fwelling ftyle, filled with redundancies the fame advantage of the other, were they both and fuperfluities of expreflion. Indeed, fome of the coolly to offer their fentiments in writing. Many ancients have attributed this loofenefs of ftyle to their things appear well in fpeaking,. which will not bear way of purfuing eloquence at firft. For as they were a ft rift ferutiny. While the hearer’s attention is put upon it by converfing with the Greek colonies obliged to keep pace with the fpeaker, he is not at who fettled among them, they fuppofe, that in imi- leifure to obferve every impropriety or incoherence, tating them, before they were mafters of the language, but many flips cafily efcapehim, which'in reading arc they were often obliged to make ufe of circumlocu- - tions, I Part III. |o| locution, tions, which afterwards became habitual, and very H i much weakened the force of their expreffions, as it naturally would do. But one would think, if they were put to this neceflity at firft, when they found its ill efFe&, they might eallly have amended it after¬ wards, as they grew better acquainted with the Greek language, had they been inclined fo to do. The Rhodian ftyle was a medium between the other two; not fo concife and expreffive as the Attic, nor yet fo loofe and redundant as the Afiatic. Quintilian fays, it had a mixture of its author, and the humour of the people ; and, like plants fet in a foreign foil, degene¬ rated from the Attic purity, but not fo wholly as to lofe it. They firft received it from iEfchines, who being worded in his famous conteft with Demofthenes, re¬ tired thither, and taught rhetoric, which put them upon the ftudy of eloquence. The ftyle of the fame country likewife very much alters in different ages. Cicero tells us, that the firft I Latin hiftorians aimed at nothing more than barely to make themfelves intelligible, and that with as much brevity as they could. Thofe who fuceeeded them advanced a ftep further; and gave fomewhat a better turn and cadency to their fentences, though ftill withr out any drefs or ornament. But afterwards, when the Greek language became falhionable at Rome, by co¬ pying after their writers, fuch as Herodotus, Thucy¬ dides, Xenophon, and others, they endeaveured to in¬ troduce all their beauties into their own tongue, which in Cicero’s time was brought to its higheft perfeflion. J3ut it did” not long continue in that date. A dege¬ neracy of manners foon altered their tafte, and cor¬ rupted their language, which Quintilian very much complains of in his time. The cafe was the fame with refpedf to the Greek tongue ; though that had the good fortune to continue its purity much longer than the Latin. Nor can any language be exempt from the common fate of all human produftions; which have their beginning, perfeftion, and decay. Befides, there is a fort of fafliion in language, as well as other I things, and the generality of people are always fond of running into the mode. Perhaps fome one, or a few perfons, fall into a manner which happens to pleafe. This gives them a reputation ; and others im¬ mediately copy after them, till it generally prevail. Cicero tells us, that the mod ancient Greek orators, whofe writings were extant in his time, fuch as Peri- ■ cles, Alcibiades, and others, were fubtle, acute, con¬ cife, and abounded in fenfe rather than words. But another fet that followed them, of which were Critias, Theramenes, and Lyfias, retained the good fenfe of the former, and at the fame time took more care of their ftyle ; not leaving it fo bare as the former had done, but furniihing it with a better drefs. After thefe came Ifocrates, who added all the flowers and beauties of eloquence. And as he had abundance of followers, they applied- thefe ornaments and decora¬ tions according to their different genius; fome for pomp and fplendour; and others to invigorate their ftyle, and give it the greater force and energy. And in this latter way Demofthenes principally excelled. Now as each of thefe manners had its peculiar beau¬ ties, and generally prevailed indifferent ages; Cicero think this could not have happened otherwife than 5717 from imitation. And he attributes it to the fame Elocution, caufe, that afterwards they funk into a fofter and " fmoother manner, not lefs exa£t and florid, but more cold and lifelefs. If we take a view of our own tongue, Chaucer feems to have been the firft who made any confiderable attempts to cultivate it. And whoever looks into him, will perceive the difference to be fo great from what it is at prefent, that it fcarce appears to be the fame language. The gradual im¬ provements it has fince received, are very evident in the writers almoft of every fucceeding age fince that time ; and how much farther it may ftiil be carried, time only can difeover. See Language. Another caufe of the variety of ftyle arifes from the different nature and properties of language. A dif¬ ference in the letters, the make of the words, and the order of them, do all affeft the ftyle. So Quintilian obferves, that the Latin tongue cannot equal the Greek in pronunciation, becaufe it is liarfher. The Latins want two of the fofteft Greek letters, u and t; and life others of a very hard found, which the Greeks have not, as /"and q. Again, many Latin words end in m; a letter of a broad and hollow found, which never terminates any Greek word ; but v does fre¬ quently, whofe found is much fofter and fweeter. Be¬ fides, in the combination of fyllables, the letters b and d are often fo fituated, as to require too ftrong and unequal a force to be laid upon them, as in the words obverfus and adjungo. Another advantage of the Greek tongue arifes from the variety and different feat of the accents: for the Greeks often accent the laft fyllable, which both enlivens the pronounciation, and renders it more mufical; whereas the Latins never do this. But the greateft advantage of the Greeks lies in their plenty and variety of words; for which reafon they have lefs occafion for tropes or circumlocutions, which, when ufed from neceffity, have generally lefs force, and weaken the ftyle. But under thefe difadvantages, Quintilian feems to give his countrymen the bell ad¬ vice the cafe will admit of: That what they cannot do in words, they fhould make up in fenfe. If their expr^ffions are not fo foft and tender, they fhould ex¬ ceed in ftrength ; if they are lefs fubtile, they fhould be more fublime ; and if they have fewer proper words, they (hould excell in the beauty as well as num¬ ber of their figures. If this account of Quintilian be juft, that the Greek tongue does furpafs the Latin in all thefe inftances, it is certain that both of them have much greater advantages over fome modern lan¬ guages. The varying all their declinable words, both tiouns and verbs, by terminations, and not by figns, contributes very much to the fmoothnefs and harmony of their periods. Whereas in the modern languages, thofe fmall particles and pronouns, which dilUnguilh the cafes of nouns, and the tenfes and perfons of verbs, hinder the run of a period, and render the found much more rough and uneven. Befides, the ancient lan¬ guages feem to have a better and more equal mixture of vowels and confonants, which makes their pronun¬ ciation more eafy and mufical. But the chief diftindiion of ftyle arifes from the dif¬ ferent fubjeds, or matter of difeourfe. The fame way of fpeaking no more fuits all fubje&s, than the fame garment would all perfons. A prince end a peafant ought ORATORY. 5718 Elocution, ought not to have the fame drefs ; and another diffe- rent from both becomes thofe of a middle ftation in life. The ftyle therefore (hould always be adapted to the nature of the fubjedt, which rhetoricians have re¬ duced to threee ranks or degrees; the /ew or plain ftyle, the middle or temperate, and the lofty orfublbne : Which are likewife called characters, becaufe they de¬ note the quality of the fubjedt upon which they treat. This divifion of ftyle into three charadters, was taken notice of very early by ancient writers. Some have obferved it even in Homer, who feems to affign the fublime or magnificent to Ulyffes, when he reprefents him fo copious and vehement an orator, that his words came from him like a 'winter fno'w. On the contrary, he defcribes Menelaus as a polite fpeaker, but concife and moderate. And when he mentions Neftor, he reprefents his manner as between thefe two, not fo high and lofty as the one, nor yet fo low and drefled as the other; but fmooth, even, and pleafant, or, as he expreffes it, morefweet than honey. Quintilian obferves, that although accuracy and politenefs were general charadters of the Attic writers; yet among their orators, Lyfias excelled in the lo'w and familiar way ; Ifocrates for his elegancy, fmoothnefs, and the fine turn of his periods ; and De- mofthenes for his flame and rapidity, by which he car¬ ried all before him. And Gellius tells us, that the like difference was found in the three philofophers who were fent from the Athenians to Rome (before the Romans had any relifti for the polite arts) to foli- cit the remittance of a fine laid upon them for an in¬ jury done to a neighbouring ftate. Carneades, one of thofe ambaffadors, was vehement and rapid in his ha¬ rangues; CdwoHus, neat and fmooth; and Diogenes, modejl and fiber. The eloquence of thefe orators, and the agreeable variety of their different manner, fo cap¬ tivated the Roman youth, and inflamed them with a love of the Grecian arts, that old Cato, who did all he could to check it by hurrying away the ambaffa¬ dors, could not prevent their vigorous purfuit of them, till the ftudy became in a manner univerfal. And the old gentleman afterwards learned the Greek language himfelf, when it became more faftiionable. Which a con ^ a~ n°ble writer of ours * reprefents as a punifoment upon him for his former crime. It feldom happens that the fame perfon excells in each of thefe characters. They feem to require a different genius, and moft people are naturally led to one of them more than another; though all of them are requifite for an orator upon different occafions, as we lhall fhew hereafter. -Chap. V. Of the Low Style. This we fliall confider under two heads, thoughts and language; in each of which thefe feveral characters 100 are diftinguifhed from one another. I. And with refpeCt to the former, as the fubjeCts proper for this ftyle are either common things, or fuch 101 as ^10U^ ke treated in a plain and familiar way ; fo plain thoughts are moft fuitable to it, and diftinguifh it from the other characters. Now, by plain thoughts, are meant fuch as are ftmple and obvious, and feem to rife naturally from the fubjeCt, when duly confidered ; fo that any one, upon firft hearing them, would be apt to imagine they Part ini muft have occurred to himfelf. Not that this is really Elocutionlii the cafe, but becaufe the more natural a thing is, the f" more eafy it feems to be; though in reality it is often otherwife; and the perfection of art lies in its neareft refemblance to nature. And therefore, in order to fpeak plainly and clearly upon any fubjeCt, it muft firft || be duly confidered, well underftood, and thoroughly I digefted in the mind; which, though it require labour and ftudy, yet the more a perfon is mafter of what he he fays, the lefs that labour will appear in his dif- courfe. This natural plainnefs and fimplicity, with¬ out any difguife or affeCtation, very much contributes jl? to give credit to what is faid. Nor is any thing more li apt to impofe on us, than the appearance of this, when artfully affumed. Cicero’s account of the fight be¬ tween Milo and Clodius, in which Clodius was killed, is a remarkable inftance of this. “ When Clodius j| knew (fays he) that Milo was obliged to go to La- nuvium upon a folemn and neceflary occafion, he im¬ mediately haftened from Rome, the day before, to af- faffinate him before Clodius’s own houfe, as appeared afterwards by the event. And this he did at a time, 1 when his turbulent mob in the city wanted his affift- ance; whom he would not have left, but for the ad¬ vantage of that place and feafon to execute his wicked defign. But the next day Milo was in the fenate, where be continued till they broke up; then went home; changed his drefs; ftaid there fome time till his wife was ready ; and afterwards fet forward fo late, that if Clodius had defigned to return to Rome that day, he might have been here by that time. Clodius, prepared for his defign, met him on horfeback, having no cha¬ riot, no equipage, no Greek attendants as ufual; and without his wife, which was fcarce ever known: where¬ as Milo was in a chariot with his wife, wrapt up in a cloak, and attended by a large retinue of maid fer- vants, pages, and other perfons unfit for an engage¬ ment. He met with Clodius before his houfe, about five o’clock in the evening; and was prefently affault- ed from an higher ground by many armed men, who killed the coachman. Upon which, Milo, throwing off his cloak, leaped out of the chariot, and bravely defended himfelf: and thofe who were with Clodius, having their fwords drawn, fome made up to the cha¬ riot to attack Milo; and others, who now thought he j! had been killed, began to fall upon his fervants who were behind. And of thefe, fuch as had courage, and were faithful to their mafter, fome were killed; and others, when they faw the fkirmifti at the chariot, and could do their mafter no fervice (for they heard Clodius himfelf fay that Milo was killed, and really thought it was fo), did that, not by their matter’s or¬ der, not with his knowledge, nor when he was prefent, which every one would have his own fervants to do in the like circumftances. I do not fay this to fix any crime upon them, but only to relate what happened.” His meaning is, they killed Clodius; which he avoids mentioning, to render what he fays lefs offenfive. Can any thing be told in a more plain and Ample manner than this ? Here is nothing faid, but what in itfelf feems highly probable, and what one would imagine the faff might eafily fugged to any ordinary fpeda- tor. But in this, both the art and fkill of it confift. For in the whole account, as, on the one hand, Milo is ORATORY. Partlll. O R A Elocution, is fo defcribed as to render it highly improbable he could have any defign at that time againft Clodius ; fo on the other, no one circomftance is omitted which might feem proper to perfuade the hearers that Clo¬ dius was the aggreflbr in that engagement. And yet, if we may believe Afconius, the quarrel was begun by fome of Milo’s retinue, and Clodius was afterwards killed by his exprefs order. But as things are fonve- times bell iliultrated by their oppofites, we fhall here produce a contrary inftance of a very afle&ed and un¬ natural way of relating, a fafl, Val. Maximus tells us of a learned man at Athens, who, by a blow which he received by a (tone upon his head, entirely forgot all his learning, though he continued to remember every thing elfe. And therefore, as he fays, fince this mif- fortune deprived him of the greateft enjoyment of his life, it had been happier for him never to have been learned, than afterwards to lofe that pleafure. This is the plain fenfe of the ftory. But now let us hear him relate it. “ A man (fays he) of great learning at Athens, having received a blow upon his head by a (tone, retained the memory of all other things very perfeftly, and only forgot his learning, to which he had chiefly devoted himfelf. The direful and malig¬ nant wound invading his mind, and as it were defign- edly furveying the knowledge repofited there, cruelly feized on that part of it in particular from which he received the greateft pleafure, and buried the Angular learning of the man with an invidious funeral. Who fince he was not permitted to enjoy his bodies, had better never have obtained accefs to them, than after¬ wards to have been deprived of the delight they af¬ forded him.” What an unnatural way is this of re¬ lating fuch an accident, to talk of a 'ivoujid invading the viind, and furveying the knonvledge repofited there, and cruelly feizing a particular part of it, and burying it with an invidious funeral? There is nothing in the ftory could lead him to this, but an over-fondnefs to refine upon it in a very affe&ed manner. But there are two properties of plain thoughts, one of which ought conftantly to attend them in common with all thoughts, and the other is often neceflary to animate and enliven this charafter. The former of thefe is juftnefs and propriety, which is what reafon diftates in all cafes. What Cicero fays of the death of Craffus the orator, feems very juft, as well as natural. “ It was (fays he) an affli&ion to his friends, a lofs to his country, and a concern to all good men ; but foch public calamities followed upon it, that heaven feemed rather to have favoured him with death, than to have deprived him of life.” This thought feems very juft, and agreeable to the fenti- ments of a good man, as Craflus was, to choofe death rather than to outlive the happinefs of his country, to which he himfelf had fo much contributed. Quintilian has a reflexion upon a like occafion, which is not fo juft and becoming. It is upon the death of his only fon, a youth of very uncommon parts, as he reprefents him ; and for whofe ufe he had defigoed his Inf it u- tions of Oratory ; but he died before they were finiftt- ed. The paflage is this : “ I have loft him of whom I had formed the greateft hopes, and in whom I had repofed the greateft comfort of my old age. What can I do now? or of what farther ufe can I think my- felf to be, thus difappointed by heaven? What -good Vol. VIII. i O R Y. .?719 parent will pardon me, if I can any longer ftudy? and Elocution, not condemn fuch refolution, if, thus furviying all my family, I can make any other ufe of. my voice, than to accufe the; gods, and declare that providence does not rpvern the world ?” Allowance may be made for the (allies of pafiion, even in wife men, upon fome /hocking dccafions ; but when it proceeds to fuch a degree as (o become impious, it is very indecent, as well as unjuft. And all indecency is unnatural, as it is difagreeable to reafon, which always direds to a de¬ corum. That Teems to be a very natural as well as juft thought of Pliny the Younger, when he fays, “ The death of thofe perfons always appear to me too hafty and unfeafonable, who are preparing fome laft- ing work. For perfons wholly devoted to pleafures, live, as it were, from day to day, and daily fini/h the end for which they live; but thofe who have a view to pofterity, and preferve their memory by their labours, always die untimely, becaufe they leave fomething un- finifhed. We /hall mention but one more inftance ; and that in a comparative view, to make it the more evident. The two fons of Junius Brutus, the firft Ro¬ man conful, having been convided of treafon in affb- ciating with Tarquin’s party, were ordered, among others, to be put to death ; and their father not only pronounced the fentcnce, but prefided at the execu¬ tion. This fad is mentioned by feveral of the Ro¬ man hiftorians ; and, as it carries in it not only the appearance of rigorous juftice, but likewife of cruelty in Brutus, to have been prefent at the execution of his fons, they endeavour to vindicate him different ways. What Florus fays, feems rather an affedation of wit, than a juft defence of the fad. “ He beheaded them (fays he), that, being a public parent, he might ap¬ pear to have adopted the whole body of the people.” Nor does Val. Maximus come up to the cafe, who fays, “ He put off the father to ad the conful; and chofe rather to lofe his fons, than he wanting to pub¬ lic juftice.” This might be a reafon for condemning them; and would have been equally true, had he not been prefent at their execution. But Livy, whofe thoughts are generally very juft and natural, alfigns the beft reafon which perhaps can be given for his vindication, when he fays, “ Fortune made him the executioner of the fentence, who ought not to have been a fpedator.” By fortune made him fo, he reprefents it not as a matter of choice, like the other hiftorians, but of nece/fity, from the nature of his of¬ fice, which then obliged him to fee the execution of that fentence he had hirofelf before pronounced; as is the cliftom at prefent, in fome popular governments. The other property, which /hould often accompany plain and Ample thoughts, is, that they be gay and fprightly. This, as has been faid, is necefiaryto ani¬ mate and enliven , fuch difeourfes as require the low ftyle. The fewer ornaments it admits of, the greater fpirit and vivacity is requifite to prevent its being dry and jejune. A thought may be very bri/k and lively, and at the fame time appear very natural, as the effed of a ready and flowing wit. Such thoughts, attend¬ ed with agreeable turns, are very fuitablc to this ftyle; but care fliould be taken, left, while fancy is too much indulged, the juftnefs of them be overlooked. We ftiall give one inftance, in which this feems to have ■been the cafe, from a'celebrated Englifh work, where 32 H the 57^° O R A ¥ Elocution, the Ingenious writer endeavours to fliew the dlfadvan- tages of perfons not attending to their natural genius, but affecting to imitate others in thofe things for which they were not formed. “ The great misfor¬ tune (fays he) of this affe&ation is, that men not only lofe a good quality, but alfo contraA a bad onej they not only are unfit for what they are defigned, but they affign themfelves to what they are unfit for; and inftead of making a very good figure one way, make a very ridiculous one another. Could the world be reformed to the obedience of that famed di&ate, fol¬ low nature, which the oracle of Delphos pronounced to Cicero when he confulted what courfe of ftudies he fhould purfue, we (hould fee almoft every man as eminent in his proper fphere as Tully was in his. For my part, I could never confider this prepofterous repugnancy to nature any otherwife, than not only as the greateft folly, but alfo one of the moll heinous crimes; fince it is a direft oppofition to the difpofi- tion of Providence, and (as Tully expreffes it) like the fin of the giants, an aftual rebellion againft heaven.” The advantages that arife from perfons attending to their own genius, and purfuing its diftates, are here reprefented in a very lively and agreeable mannei. But there is one thing afferted, which we fear will not hold; which is, that, Could the world le reformed to that diftate, “ Follow nature,” we Jhould fee almojl every man as eminent in his proper fphere, as Tully was in his. For though doubtlefs perfons would generally fucceed beft, if they kept to this rule ; yet different degrees of ability are often found, where the bias and inclination is the fame, and that accompanied with equal labour and diligence. If this was not fo, how happened it that no one came up to Tully in the art of oratory; efpecially in his own age, when there were the greateft opportunities for that ftudy, and the higheft encouragements were given to it, as it paved the way to riches, honours, and all the grand offices of the ftate ? It cannot well be queftioned, but that there were other gentlemen, who had all the fame ad¬ vantages, accompanied with as ftrong a paffion for this art, as Tully had, who yet fell much fhort of him in point of fuccefs. And experience fhews, that the cafe has been the fame in all other purfuits. 102 III. But it is time to proceed to the other head, the language proper for this ftyle. And here it may be obferved in general, that the drefs ought to be a- greeable to the thoughts, plain, Ample, and unaffec¬ ted. But the firft thing that comes under confideration is elegance, or a proper choice of words and expref- fions; which ought always to fuit the idea they are defigned to convey. And therefore' when an ancient writer, fpeaking of cruelty, calls it mevus crudelitatis, ihe blemifo of cruelty; and another, applying the fame word to ingratitude, fays n.evus ingratitudinis, the llemijh of ingratitude; that term does not fufficiently convey to us the odious nature of either of thofe vices, as indeed it was not their defign it fhould. But other- wife, where the fpeaker has not foroe particular view in doing it, to fink too low is as much a fault, as to rife too high. So to call ancient Rome the miflrefs of Italy, would as much leffen the juft notion of the ex¬ tent of her power, as the Roman writers aggrandife it when they ftyle her mifrefs of the world. But pu- O R Y, Part III. rity, both in the choice of words and expfeffions, is Elocution, never more neceffary than it is here. This may be -1 called neatnefs in language. And to be plain and neat at the fame time, is not only very confiftent but the former can no other way recommend itfelf, than as joined with the latter. Befides, the fewer advantages any thing has to fet it off, the more carefully they ought to be obferved. Perfpicuity is always to be re¬ garded ; and ferves very much to keep up the atten¬ tion, where other ornaments are wanting. Epithets fhould be fparingly ufed, fince they enlarge the images of things, and contribute very much to heighten the ftyle. Indeed they are fometimes neceffary to fet a thing in its juft light; and then they fhould not be dropped. Thus, in fpeaking of Xerxes, it would be too low and flat to fay, He defended with his army into Greece. Here is no intimation given of their vaft and unparallelled numbers, which ought to be done. Herodotus fays, his whole army, of fea and land for¬ ces, amounted to 2,317,000 and upwards. There¬ fore, unlefs the number be mentioned, the leaft that can be faid is, that he defended with a vaf army. The next thing to be regarded is compofition, which here does not require the greateft accuracy and exaftnefs. A'feeming negligence is fometimes a beau¬ ty in this ftyle, as it appears more natural. Short fentences, or thofe of a moderate length, are likewife upon the whole beft fuited to this charafter. Long and accurate periods, finely wrought up with a gradual rife, harmonious numbers, a due proportion of the feveral parts, and a juft cadency, are therefore impro¬ per, as they are plainly the effeft of (art. But yet fome proportion fhould be obferved in the members, that neither the ears be too much defrauded, nor the fenfe obfcured. Of this kind is that expreffion of a Greek orator, blamed by Demetrius: Ceres came rea¬ dily to our affiance, hut Arfiides not. The latter member of this fentence is too fhort; and by dropping fo fuddenly, both difappoints the ears, and is fome- what obfcure. It would have been plainer, and more agreeable thus, hut Arifiides did not come. As to or¬ der, the plaineft and cleareft difpofition, both of the words and members of fentences, and what is molt agreeable to the natural conftruclion, beft fuits with this charadter. For one of its principal beauties is perfpicuity. And a proper conne&ion likewife of fentences, with a regular order in the dependence of things one upon another, very much contribute to this end. With regard to the collifion of fyllables in dif¬ ferent words, for preventing either an hollownefs or afperity of found, greater liberty may be taken in this ftyle than in the other charaflers. Here it may be al¬ lowed to fay, Virtue is amiable to all, though all do not purfue it. But in an higher charafter, perhaps, in order to prevent the hollow found of the words though all, a perfon would choofe to vary the expref¬ fion a little, and fay, though few purfue it. So, Xerxes' expedition, may be tolerable here ; but in the florid ftyle, the expedition of Xerxes would found much better. The laft thing thing to be confidered, with refpedl to the language, is dignity, or the ufe of tropes and figures. And as to tropes, they ought to be ufed cau- tioufly ; ualefs fuch as are very common, and by time have either come into the place of proper words, or at leaft Part III. ORATORY. Elocution, lead equally plain and clear. So in the inftancemen- tioned above, Diodorus Siculus, fpeaking of the forces of Xerxes, calls them an innumerable company. Where, by a fynecdoche, he has chofe to make ufe of an uncertain number for a certain, as lefs liable per¬ haps to exception. Other examples might be given if neceflary. And with regard to figures, as moft of thofe which confift in words, and are therefore called verbal figures, ferve chiefly to enliven an expreflion, and give an agreeable turn, they are often not impro¬ per for this charafler. Nor are figures of fentences wholly to be excluded, efpecially fuch as are chiefly ufed in reafoning or demonftration. But thofe which ■re more peculiarly adapted to touch the pafilons, or paint things in the ftrongeft colours, are the more proper ornaments of the higher ftyles, as will be ftiewn hereafter. Upon the whole, therefore, pure nature, without any colouring, or appearance of art, is the diftinguilh- ing mark of the low ftyle. The defign of it is to make things plain and intelligible, and fet them in an eafy light. And therefore the proper fubje&s of it are epiftles, dialogues, philofophical diflertations, or any other difcourfes, that ought to be treated in a plain and familiar manner, without much ornament, or ad- drefs to the pafiions. A freedom and eafe both of thought and expreffion, attended with an agreeable humour and pleafantry, are its peculiar beauties that engage us. As we fee perfons of faftiion and good breeding, though in the plaineft habit, have yet fome- thing in their air and manner of behaviour that is very taking and amiable. Somewhat of the like na¬ ture attends this ftyle. It has its difficulties, which are not fo eafily difeerned, but from experience. For it requires no fmall Ikill, to treat a common fubjeft in fuch a manner as to make it entertaining. The fewer ornaments it admits of, the greater art is neceflary to attain this end. Lofty fubjefls often engage and cap¬ tivate the mind by the fublimity of the ideas. And the florid ftyle calls in all the affiftance of language and eloquence. But the plain ftyle is in a great mea- fure ftripped of thofe advantages; and has little more to recommend it, than its own native beauty andfim- plicity. Chap. VI. Of the Middle Style. *0$ This we fhall treat in the fame manner as we did the former, by confidering firft the matter, and then the language proper for it. 104 I. And as the fubjeds proper for this ftyle are things of weight and importance, which require both a gravity and accuracy of expreffion; fo fine thoughts are its diftinguiftn'ng-mark, as plain thoughts are of the low charadfer, and lofty thoughts of the fub- lime. Now a fine thought may deferve that cha- rafter from fome or other of the following proper¬ ties. . And the firft property we fhall mention is gravity and dignity. Thus Cicero in a fpeech to Csefar fays, “ It has been often told me, that you have frequent¬ ly faid, you have lived long enough for yourfelf. I be¬ lieve it, if you either lived, or was born for yourfelf only.” Nothing could either he more fit and proper, than this was, when it was fpoken; or at the fame time a finer compliment upon Csfar. For the civil 57JI was now over, and the whole power of the Ro- Elocution, man government in the hands of Csefar; fo that he might venture to fay, he had lived long enough for himfelf, there being no higher pitch of glory to which his ambition could afpire. But then there were many things in the ftate that wanted redreffing, after thofe times of diforder and confufion, which he had not yet been able to effect, and of which Cicero here takes an opportanity to remind him. We ftiall produce an¬ other example from Curtins. Philotas, one of Alex¬ ander’s captains, having formed a confpiracy agaioil him, was convidled of it, and put to.death. Amin- tas, who was fufpefted of the fame crime, by reafon of his great intimacy with Philotas, when he comes to make his defence, among other things fpeaks thus : “ I am fo far from denying my intimacy with Philo¬ tas, that I own I courted his friendftiip. Dp you wonder that we ffiewed a regard to the fon of Parme- nio, whom you would have to be next to yourfelf, gi¬ ving him the preference to all your other friends ? You, Sir, if I may be allowed to fpeak the truth, have brought me into this danger. For to whom elfe is it owing, that thofe who endeavoured to plcafe you, ad- drefled themfelves to Philotas? By his recommenda¬ tion we have been raifed to this fhare of your friend- fhip. Such was his intereft with you, that we court¬ ed his favour, and feared his difpleafure. Did we not all in a manner engage ourfelves by oath, to have the fame friends, and the fame enemies, which you had ? Should we have refufed to take this, which you as it were propofed to us ? Therefore, if this be a crime, you have few innocent perfons about you ; nay, indeed none. For all defired to be the friends of Philotas; though all could not be fo, who defired it. There¬ fore, if you make no difference between his friends and accomplices, neither ought you to make any be¬ tween thofe who defired to be his friends, and thbfe who really were fo.” Could any thing be finer fpoken, more proper, and becoming the character of a fol- dier, than this defence ; efpecially to a prince of fo great and generous a fpirit as Alexander ? There is fomething which appears like this in Tacitus with re¬ lation to the emperor Tiberius, but falls vaftly ftiort of it in the juftuefs and dignity of the fentiment. Se- janus, his great favourite, and partner in his crimes, falling under his difpleafure, was, like Philotas, put to death for a confpiracy. Now a Roman knight, who apprehended himfelf in danger on account of his friendftiip with Sejanus, thus apologizes for him¬ felf to the emperor, in the manner of Amintas: “ It is not for us to examine the merit of a perfon whom you raife above others, nor your reafons for doing it. The gods have given you the fovereign power of all things, to us the glory of obeying. Let confpiracies formed againft the ftate, or the life of the emperor, be puniftied ; but as to friendlhips and private regards, the fame reafon that juftifies you, Ceefar, renders us innocent.” The turn of the expreffions is not much different from that in the cafe of Amintas; but the beauty of the thought is fpoiled, by the flattery of complimenting Tiberius upon an excefs of power, which he employed to the deftru&ion of many excel¬ lent men. There is not that impropriety in the de¬ fence of Amintas, which is equally brave and juft. Another property of a fine thought is beauty and 32 H 2 elegancy 5721 Elocution.. ORATORY. elegaxc?. It is a fine compliment which Pliny pays to 'the emperor Trajan, when he fays : 11 It has happen¬ ed to you alone, that you was father of your country, before you was made fq.” Some of the Roman em¬ perors had been complimented with the title of father of their country, who little deferved it. But Trajan had a long time refufed it, though he was really fo, both by his good government, and in the efteem of his fubjedts, before he thought fit to accept of it. And Piiny, among other inftances of the generofity of that prince, which he mentions in the fame dif- courfe, fpeaking of the liberty that he gave the Ro¬ mans to purchafe eftates which had belonged to the emperors, and the peaceable poffeffion they had of them, does it by a turn of thought no lefs beautiful than the former. “ Such (fays he) is the prince’s bounty, fuch the fecurity of the times, that he thinks us worthy to enjoy what has been poffeffed by em¬ perors ; and we are not afraid to be thought fo.” There is a fpritelinefs in this image, which gives it a beauty ; as there is likewife in the following paffage of the fame difcourfe, where he fays to Trajan, “ Your life is difpleafmg to you, if it be not joined with the public fafety ; and you fufifer us to wifli you nothing but what is for the good of thofe who wifh it.” And of the fame kind is that of Cicero to Cse- far, when he fays: “ You, Csefar, are wont to for¬ get nothing. but injuries.” It is a very handfome, as well as juft reflection, made by Tacitus upon Galba’s government, that, “ He feemed too great for a pri¬ vate man, while he was but a private man ; and all would have thought him worthy of the em¬ pire, had he never beeen emperor.” The beauty of a thought may give us delight, though the fubjedt be forrowful; and the images of things in them- felves unpleafant, may be fo reprefented as to become agreeable. Sifigambis, the mother of Darius, after the death of her fon, had been treated by Alexander with the greateft regard and tendernefs, in whofe power (he then was. So foon as (he heard therefore that he was dead, (he grew weary of life, and could not bear to outlive him. Upon which QACurtius makes this fine refledtion: “ Though (he had cou¬ rage to furvive Darius, yet (he was afliamed to outlive Alexander.” The next property of a fine thought, which we (hall mention, is delicacy. As, in the objedts of pur fenfes, thofe things are faid to be delicate which aflecl us gradually in a foft and agreeable manner; fo a delicate thought is that which is not wholly difcovered at once, but by degrees opening and unfolding itfelf to the mind, difclofes more than was at firft perceived. Quintilian feems to refer to this, when he fays, “ Thofe things are grateful to the hearers, which when they apprehend, they are delighted with their own fagacity ; and pleafe themfelves, as though they had not heard, but difcovered them.” Such thoughts are not unlike the (ketches of fome pictures, which let us into the defign of the artift, and help us to dif- eern more than the lines themfelves exprefs. Of this kind is that of Sallult : “ In the greateft fortunes, there is the lead liberty.” This is not often fo in fadt, but ought to be; both to guard againft an abufe of power, and to prevent the effeds of a bad example to inferiors. Piiny, fpeaking of the emperor Traj.an’s Part III. entry into Rome, fays : “ Some declared, upon fee- Elocution, tug yog, they had lived long enough ; others, that. '**• now they were more defirous to live.” The compli¬ ment is fine either way, fince both muft efteem the fight of him the greateft happinefs in life ; and in that confiftency lies the delicacy of the thought. It was a fine charader given of Grotius, when very young, on the. account of his furprifing genius and uncommon proficiency in learning, that he 'was ‘horn a man : As if nature, at his coming into the world, had at once furniftied him with thofe endowments which others gradually acquire by iludy and appli¬ cation. The laft property of a fine thought, which we (hall take notice of, is novelty. Mankind is naturally plea- fed with new things ; and when at the fame time they are fet in an agreeable light, this very much heightens the pleafure. Indeed there are few fubjeds, but what have been fo often confidered, that it is not to be ex- peded they (hould afford many thoughts entirely new; but the fame thought fet in a different light, or ap¬ plied to a different occafion, has in fome degree a claim of novelty. And even where a thing hath been fo well, faid already, that it cannot eafily be mended, the revival of a fine thought often affords a pleafure and entertainment to the mind, though it can have no longer the claim of novelty. Cicero, in his treatife of an orator, among feveral other encomiums which he there gives to Craffus, fays of him : “ Craffus al¬ ways excelled every other perfon, but that day he ex¬ celled himfelf.” He means as an orator. But elfe- where he applies the fame thought to Caefar, upon another account; and with fome addition to it. “ You had (fays he) before conquered all other conquerors by your equity and clemency, but to-day you have con¬ quered yourfelf; you feem to have vanquKhed even yi&ory herfelf, therefore you alone are truly invin¬ cible.” This thought, with a little variation of the phrafe, has fince appeared in feveral later writers ; and it is now grown common to fay of a perfon, who ex- cells in any way, upon his doing better than he did before, that he has outdone himfelf. The like has happened to another thought, which, with a little al¬ teration, has been varioufly applied. It was faid by Varro, That if the Mufes 'were to talk Latin, they 'would talk like Plautus. The younger Pliny, apply¬ ing this compliment to a friend of his, fays, His let¬ ters are fo finely 'written, that you 'would think the Mu¬ fes themfelves talked Latin. And Cicero tells us, It •was faid of Xenophon, that the Mufes themfelves feem¬ ed to fpeak Greek •with his voice. And elfewhere, that Philofopbers fay, if Jupiter fpeaks Greek, he mujl fpeak like Plato. The thought is much the fame in alUhefe inftsnces, and KaS been fince revived by fome modern writers. II. We (hall now confider the language proper for I0- the middle ftyle. And in general it may be obftrved, ' that as the proper fubje'As of it are things of weight and importance, though not of that exalted nature as wholly to captivate the mind and divert it from attending to the didtion; fo all theornainents offpeeeh, and beauties of eloquence, have place here. And firll with regard to elegance, it is plain that a different choice of words makes a very great difference iii.ihe ftyle, where the ftnfe is the fame.. Sometimes one. Partlll. ORATORY. 5723 'locution. one fmgle word adds a grace and weight to an ex- preffion, which, if removed, the fenfe becomes flat and lifelefs. Now fuch words as are moft full and expreflive, fuit beft with this charafter. Epithets alfo, which are proper and well chofen, ferve very mtich to beautify and enliven it, as they enlarge the ideas of things, and fet them in a fuller light. The mod accurate compofition, in all the parts of it, has place here. Periods, the moft beautiful and harmonious, of a due length, and wrought up with the moft exacl order, juft cadency, eafy and fmooth connexion of the words, and flowing numbers, are the genuine ornaments, which greatly contribute to form this charafter. But the principal diftinftion of ftyle arifes from tropes and figures. By thefe it is chiefly animated and raifed to its different degrees or characters, as it receives a lefferor greater number of them; and thofe either more mild, or ftrong and powerful. As to tropes, thofe which afford the moft lively and pleafing ideas, efpecialiy metaphors, fuit the middle charadter. It is a pretty remark, which has been made by fome critics upon two verfes of Virgil ; one in his Eclogues, and the other in his Georgies. The former of thefe works is for the moft part written in the low ftyle, as the language of Ihepherds ought to be ; but the latter in the middle ftyle, fuitable to the nature of the fubjed, and the perfons for whom it was defigned, the greateft men in Rome not think¬ ing it below them to entertain themfelves with rural affairs. Now in the Eclogue, as fome copies read the verfe, the Ihepherd, complaining of the barrennefs of his land, fays: Infelix folium ct fteriles najamtar avenx. In Englilh thus: Wild oats ami darnel grow inflead of corn. But in the Georgic, where the fame fenfe is in¬ tended, inftead of the proper word nafeuntur, grow, the author fubftitutes a metaphor, dominantur, com¬ mand, and fays : Infrtix folium et Jferiles dominantur avenx. That is in Englilh : Where corn is fown, darnel and oats command. It was fit and natural for the Ihepherd to exprefs his fenfe in the plained terms; and it would have been wrong to reprefent him going fo far out of bis way, as to fetch a metaphor from government, in talking up¬ on his own affairs. But in the Georgic, where the poet fpeaks in his own perfon, the metaphor is much more beautiful, and agreeable to the dignity of the work. This inftance may (hew in fome meafure how the ftyle is heightened by tropes, and the fame thought may be accommodated to the feveral cbara&ers of ftyle by the different manner of expreffion. The like may alfo be faid of figures either of words or fentences, in reference to this chara&er ; which ad¬ mits of thefineft deferiptions, moft lively images, and brighteft figures, that ferve either for delight, or to influence the pafiions without tranfport or eeftafy, which is the property of the fublime. This is indeed the proper feat of fuch embdlilhments, which fupport and make up a principal part of the middle or florid ftyle. Having treated largely upon thefe in feveral preceding chapters, we (hall here only briefly mention Elocution, fome of the moft confiderable. Deferiptions are not only a great ornament to a dif- i©6 courfe, but reprefent things in a very lively and agree¬ able manner. In what a beautiful light has Cicero placed the polite arts and fciences, when, deferibing them from their effetSs, he thus reprefents to us the great advantages, as well as pleafure, which they af- ford to the mind ? “ Other ftudies neither fuit with all times, nor all ages, nor all places : but thefe im¬ prove youth, delight old age, adorn profperity, afford a refuge and folace in adverfity ; pleafe at home, are no hindrance abroad; fleep, travel, and retire with us.” And they often affecl us very powerfully, when they are addreffed to the fenfes. Quintilian has painted the calamities of a city taken by ftorm in the brighteft and ftrongeft colours, which he reprefents by “ Flames fpreading themfelves over the houfes and temples, the cracking of falling buildings, and a confufed noife from a variety of cries and fliouts; fome running they know not where, others in the laft embraces of their friends, the fhrieks of children, women, and old men unhappily referred to fuch diftrefs ; the plundering of all places civil and facrcd, the hurry and confufion in carrying off the booty, captives driven before their vi&ors, mothers endeavouring to guard their infants, and quarrels among the conquerors where the plun¬ der is largeft.” This feems to be a very natural, as well as moving, image of fo dreadful a calamity. Profopopeia is another very ftrong and beautiful fi- 107 gure, very proper for this charatter. Seneca has a fine inftance of it in his Confolotary letter to Marcia, upon the death of her fon. After many arguments he had made ufe of to alleviate her grief, he at laft introduces her father, Cremutius Cordus, as thus ad¬ drefling to her: “ Imagine your father (fays he) from the celeftial regions, fpeaking to you in this manner: Daughter, why do you fo long indulge your grief? why are you fo ignorant, as to think it unhappy for your fon, that, weary of life, he has withdrawn himfelf to his anceftors ? Are you not fenfible what diforders for¬ tune occa lions every where? and that (he is kindeft to thofe who have lealt concern with her ?. Need I men¬ tion to you princes who had been extremely happy had a more timely death fecured them from impend¬ ing evils ? or Roman generals, who wanted nothing to confummate their glory, but that they lived too long ? Why then is he bewailed longeft in our family, who died moft happily ? There is nothing, as you imagine, defirable among you, nothing great, no¬ thing noble; but, on the contrary, all things are mean, full of trouble and anxiety, and partake very little of the light which we enjoy.” This advice was very fuitable for a philofopher; and he feems to have chofen. this way of introducing it, to enforce the ar¬ gument drawn from the happinefs of good men in a future ftate, from the teftimony of a perfon who was atftually in the poffeffion of it. Similitudes and comparifons are another great orna- jog' ment of this ftyle, and ofteneft found here. Nothing can be finer than the comparifon between thofe two great orators, Demofthenes and Cicero, made by Quintilian, when he fays : “ Demofthenes and Cicero differ in their elocution ; one is more clofe, and the other more copious; the former concludes more con- 5,724 Elocution. 109 110 lit ORA cifely, and the latter takes a larger compafs; the one always with pungency, and the other generally with weight; one can have nothing taken from him, and the other nothing added to him ; the latter has more of art, and the former more of nature. But thismnft be allowed to Demofthenes, that he made Cicero in a great meafure what he was. For as Tully gave himfelf wholly to an imitation of the Gfeeks, he feems to me to have expreffed the force of Demofthenes, the fluen¬ cy of Plato, and the pleafantry of Ifocrates.” Simili¬ tudes, taken from natural things, ferve very much to enliven the ftyle, and give it a cheerfulnefs ; which is a thing fo common and well known, that we need not ftay to give any inftances of it. Antithejis, or oppofition, both in the words and fenfe, has often the like beautiful effeft. There is an agreeable contraft in that pafiage of Seneca : “ Cse- far does not allow himfelf many things, becaufe he can do all things: his watching defends all others fleep, his labour their quiet, his induftry their plea- fure, his bufinefs their eafe ; fince he has governed the world, he has deprived himfelf of it.” Had he faid no more than only in general, that, Cxfar doet not allow himfelf many things% hecaufe he can do all things, it might have paffed for a fine thought; but, by adding fo many particulars, all in the fame form of expreffion, and beginning each member with the fame word, he has both enlarged the idea, and beauti¬ fied the antithefis, by a bright verbal figure. Thefe, and fuch like florid figures, are fometimes found in hiftorians, but oftener in orators ; and in¬ deed this middle charaSer, in the whole of it, is beft accommodated to the fubjefts of hiftory and ora¬ tory. Chap. VII. Of the Sublime Style. The fublime is the moft noble, as well as the mod difficult part, of an orator’s province. It is this prin¬ cipally which Cicero requires in his perfect orator, whom he could not defcribe in words, but only con¬ ceive of in his mind. And indeed, the nobleft ge¬ nius and greateft art are both requifite to form this chara£ter. For where nature has been moft liberal in furnifliing the mind with lofty thoughts, bright ima¬ ges, and ftrong expreffions ; yet without the affiftance of art there will fometimes be found a mixture of what is low, improper, or mifplaced. And a great genius, like a too rich foil, muft produce flowers and weeds promifcuoufly, without cultivation. But the jufteft propriety, joined with the greateft ftrength and higheft elevation, of thought, are required to complete the true fublime. Art therefore is neceftary to regulate and perfeft the tafte oTthofe who are defirous to ex¬ cell in this chara&er. In explaining the nature and properties of this cha- rafter, we {hall, as in the two former, co.nfider firft the thoughts, and then the language, in each of which it is diftinguiftted from them. $ i. Sublime, as it relates to Thoughts. Lofty and grand fentiments are the bafis and foun¬ dation of the true fublime. Longinus therefore ad- vifes thofe who afpire at this excellence, to accuftom themfelves to think upon the nobleft fubje&s. A mind that always dwells upon low and common fubjefts, TORY. Partlll. can never raife itfelf fufficiently to reprefent things Elocution, great and magnificent in their full extent and proper " light. But he who inures himfelf to conceive the higheft and moft exalted ideas, and renders them fa¬ miliar to his thoughts, will not often be at a lofs how to exprefs them ; for where proper words are want¬ ing, by metaphors and images taken from other things he will be able to convey them in a juft and adequate manner. What is more common than for two perfons to conceive very differently of the fame thing from, the different manner of thinking to which they have been accuftomed ? After the great battle in Cilicia, between Alexander and Darius, in which the latter was routed, he fent ambaffadors to Alexander with propofals of peace, offering him half his king¬ dom with his daughter in marriage. Parmenio, one of Alexander’s chief captains, fays to him upon this occafion : “ For my part, was I Alexander, I would accept of thefe conditions.” “And fo would I,” replies that afpiring monarch, “ was I Parmenio.” The half of fo vaft a kingdom at prefent, and a right of fuc- ceffion to the whole by marriage, was the higheft am¬ bition to which the thoughts of Parmenio could rife. But Alexander had vaftly higher views, he aimed at nothing lefs than univerfal monarchy ; and therefore fuch a propofal feemed much beneath his regard. Noble and lofty thoughts are principally thofe which either relate to divine objeds, or fuch things as a- j mong men are generally efteemcd the greateft and moft illuftrious. Of the former fort is that of Homer, when defcri- bing the goddefs Difcord, he fays, that (he Walks on the ground, and hides her head in clouds. Tliis ftretch of thought, fays Longinus, as great as the diftance between heaven and earth, does not more reprefent the ftature of the goddefs, than the meafure of the poet’s genius and capacity. But fuch images, however beautiful in poetry, are not fo proper for an orator, whofe bufinefs it is to make choice of thofe which are fuited to the nature of things and the com¬ mon reafon of mankind. When Numa the fecond king of Rome was fettled in his government, and at peace with his neighbours, in order to foften the fierce and martial temper of his fubje&s, who had been al¬ ways accuftomed to wars during the reign of his pre- deceffor Romulus, he endeavoured to imprefs their minds with an awe of the Deity; and for that end in¬ troduced a number of religious ceremonies, which he pretended to have received from the goddefs Egeria. This muft be efteemed an artful piece of policy at that time. But that fentiment is far more juft and noble, with which Cicero endeavours to infpire the members of a community, in his treatife Of Laws, when he fays, that “ Citizens ought firft to be per- fuaded, that all things are under the rule and govern¬ ment of the gods ; that every affair is directed by their wifdom and power; that the higheft regard is due to them from men, fince they obferve every one’s conduft, how he a&s and behaves himfelf, and with what temper and devotion he worfliips them ; and that they make a difference between the pious and impious.” Perfons under the influence of fuch a per- fuafion, could not fail of behaving well in fociety. And what he fays to Caefar is no lefs in this ftyle, < when, interceding for Ligarius, he tells him, that “ men Part III. ORA'] locution. “ men in nothing approach nearer to deity, than in giving life to men.” And Velleius Paterculus, fpeak* ing of Cato, gives him this fublime chara&er, “ That he was more like the gods than men; who never did a good thing, that he might feem to do it.” The other kind of lofty thoughts mentioned above, are thofe which relate to power, wifdom, courage, beneficence, and fuch other things as are of the higheft efteem among mankind. “ Your fortune (fays Tully to Caefar) has nothing greater than a power, nor your nature than a will, to fave many.” He fubjoins this compliment to what we juft now cited from him; and applies that to Csefar, which was before only ex- prefied in general, leaving him to draw the inference of his fimilitude to deity from the clemency of his nature. And elfewhere, as in a fort of tranfport for his fuccefs in defeating the confpiracy of Catiline, he thus befpeaks the Roman fenate: “ You have always decreed public thanks to others for their good govern¬ ment of the ftate, but to me alone for its prefervation. Let that Scipio fhine, by whofe conduft and valour Hannibal was forced to leave Italy, and retire to Africa ; let the other Scipio be greatly honoured, who deftroyed Carthage and Numantia, two cities the moft dangerous to this empire; let Lucius Paulus be in high efteem, whofe triumphal chariot was adorned with Perfes, once a moft powerful and noble prince; let Marius be in eternal hunour, who twice delivered Italy from an invafion and the dread of fervitude; let Pompey’s name excel all thefe, whofe aftions and vir¬ tues are terminated by no other bounds but the courfe of the fun: yet, among all their praifes, there will (till fome place be left for my glory; unlefs indeed it be a greater thing to open for us new provinces to which we may refort, than to fecure a place for our victorious generals to returrt in triumph.” And Vel¬ leius Paterculus, as if he thought no encomium too high for this great orator, laments his unhappy fate in thefe lofty ftrains, addreffed to M. Antony, by whofe order he was put to death: “ You have taken from Cicero old age, and a life more miferable than death under your government; but his fame, and the glory of his aCtions and words, you have been fo far from deftroying, that you have increafed them. He lives, and will live in the memory of all ages ; and while this fyftem of nature, however conftituted, fhall remain, (which fcarce any Roman but himfelf con¬ ceived in his mind, comprehended by his genius, and illuftrated with his eloquence), the praife of Cicero lhall accompany it; and all pofterity, whilett admires his writings againit you, will curfe your treatment of him; and fooner fhall mankind be loft to the world, than his name.” It was a noble reply of Porus the Indian king, when, after his defeat by Alexander, being brought before him, and afked, Ho22 In the introduction, the orator has three things be¬ fore him ; to gain the efteem of his hearers, to fecure their attention, and to give them fome general no¬ tion of his fubjeft. To fet out modeftly, is undoubt¬ edly the mod likely way to recommend himfelf. For to attempt to inflame an audience, before they are prepared for it, or fee the reafon of much warmth, is highly improper. A prudent fpeaker wfll, like De- mofthenes, begin with temper, and rife gradually, till he has infenfibly warmed his hearers, and in fome degree engaged their affections in his favour. So that this part fcarce rifes above the middle ftyle. And if it carry in it an air of pleafantry and good- humour, it is generally the more apt to engage the attention. 123 The introduction is ufually followed by the narra¬ tion, or a recital of fuch things as either preceded, ac¬ companied, or followed upon the fubjeCt under confi- deration. Now as the qualities that recommend a narration are clearnefs, brevity, and probability; thefe fufficiently point out the ftyle. Perfpicuity arifes from the choice of proper words, and fuch tropes as have been rendered molt familiar by ufe ; brevity re¬ quires moderate periods, whofe parts are but little tranfpofed ; and a plain and Ample drefs, without or¬ nament or colouring, is beft fuited to reprefent things probable : all which are the properties of the low ttyle. And therefore Cicero fays, narrations come pretty near to our ordinary difcourfe. Indeed, fome- times it is neceflary not only to relate the faCts them- felves, but likewife to defcribe the manner in which they were performed. And then a further degree of art may be requifite to reprefent them with all their circumftances, and paint them to the mind in their proper colours. 324 The next part in order is the propoftion, or fubjeCt of the difcourfe, in which there can be no room for ornament. But as it is the bafis and foundation of the orator’s whole defign, it ought to be laid down in the Part IH.i plained and cleared terms, fo as to leave no ro6m for Elocution.] doubt or uncertainty what it is which he intends to - difcourfe upon. The next thing is confirmation, wherein the orator 125 j endeavours to maintain and defend his own caufe, and to convince his hearers of the truth of it by reafon and argument. Now the low ftyle is certainly fitted for cool reafoning and debate. But the orator’s me¬ thod of reafoning often very much differs from that of the philofopher. The latter contents himfelf with the \ mod plain and familiar manner of reprefenting the truth, and thinks it fufficient if what he lays be clear¬ ly underftood. But t.he former, at the fame time that be convinces the judgment, endeavours likewife to af- fe& the paflions, and that in a great variety of ways. So that in this part of the difcourfe the ftyle is very different, according to the nature and circumftances of the caufe. Sometimes, while he is dwelling upon the proof of a thing, he talks coolly, and reafons with the fedatenefs of a philofopher; and where any part of his argument appears doubtful or obfeure, he endeavours with the fame even temper to explain and clear it up. But frequently he intermixes with his proofs all the art's of perfuafion, and embellifties his reafons with the greateft ornaments and beauties of elo¬ quence. Confirmation is ufually followed by confutation, in 126 which the orator endeavours to enervate and over¬ throw all that has been advanced in favour of the op- pofite fide of the queftion. But as the ftyle is much the fame here as in the former part ; what has been faid*upon this, may be fufficient for this like¬ wife. The laft part above-mentioned is the conclufion, 127 This confifts of two branches, recapitulation and ad- drefs. Recapitulasion is a fliort recital of the feveral arguments, or at lead the chief of them, which were before advanced in fupport of the caufe ; that, being brought together into a narrow compafs, they may appear in a ftronger light. Wherefore the language here ought rather to be forcible and ftrong than flo¬ rid, becaufe brevity and concifenefs is a neceffary qua¬ lity. The other branch of the conclufion confifts in an addrefs to the paffions, and is wholly perfuafive; for which the fpeaker is now entirely at leifure. In¬ deed, this is often done occafionally in other parts of the difcourfe, particularly in the introduflion and con¬ firmation : But as in the former of thefe, his view is principally to fecure the good opinion of the hearers, and excite their attention ; an<3 in the latter to defend his own fide of the queftion by reafon and argument; when thefe two points are gained, he has nothing left but to prevail with them to fall in with his defign, and declare for him. And the beft way to attain this is, by engaging their paflions in his intereft. Hence then, to ufe Quintilian’s words, “ All the fprings of elo¬ quence are to be opened. Now we are paft the rocks and (hallows, all the fails may be hoifted. And as the greateft part of the conclufion confifts in illuftration, the raoft pompous language and ftrongeft figures have place here.” All the variety above-mentioned, however, is not always neceflary. Regard muft be had to the nature of the fubjeft, the time, place, perfons, and other cir¬ cumftances ; by all which the ftyle is to be regulated. IV. ORATORY. 5731 i- To difcoorfe in a lofty and grand way upon a common mentions feveral among tlie Greeks, and feme few Prommcii- topic, or in a low and flat manner upon a fublime ar- among the Romans, who excelled in one or other of tl0n‘ gument, are both equally injudicious. Cicero refers thefe different kinds; yet one who excelled in them us to fome difeourfes of his own, as inftances of each all, he fuppofes never to have exifted, except in the kind. His oration for Csscina, he fays, is written in imagination. The reafon perhaps may be, becaufe the low ftyle, that for the Manilian law in the middle each of them feems to require a very different genius, ftyle, and that for Rabirius in the fublime ; and his fo that it is fcarce poffible for the fame perfon to fuc- Aftions againft Verres, with fome others, are patterns -ceed in them all. Since therefore it is fo rare and dif- of the variety here mentioned. And he gives us a very ficult a matter to gain the command of each in any comprehenfive defeription of a perfed orator in a very good degree, it is better perhaps for every one to pur- few words, when he fays : “ He is one who can fue that which nature feems moft inclined to, and to fpeak upon a low fubjeft acutely, upon a lofty fubjeft excel in it, than to drive againd their genius. For with fublimity, and upon a moderate fubjeA tempe- every kind has its perfe&ions; and it is morecommen- rately.” By which he means no more, than one who dable to be raader of one thing, than to do feveral but is mader of the three chara&ers here deferibed, and indifferently, knows when and how to ufe them. But although he Part IV. Of P R O N U N C I A T I O N. Chap. I. Of Pronunciation in general. Ronunctation is alfo called Attion by fome of the ancients. Though if we attend to the proper fig- nification of each of thefe words, the former refpedts the voice, and the latter the gedures and motions of the body. But if we confider them as fynonymous terms, in this large fenfe pronunciation or a&ion may be faid to be, a fuitable conformity of the voice, and the fcveral motions of the body, in fpeaking, to the fubjett mat¬ ter of the difeourfe. The bed judges among the ancients have reprefent- ed this as the principal part of an orator’s province, from whence he is chiefly to expeft fuccefs in the art of perfuafion. When Cicero, in the perfon of Craflus, has largely and elegantly difeourfed upon all the other parts of oratory, coming at lad to fpeak of this, he lays: “ All the former have their effeft as they are pronounced. It is the aftion alone that governs in fpeaking ; without which the bed orator is of no va¬ lue, and is often defeated by one in other refpefls much his inferior.” And he lets us know, that De- modhenes was of the fame opinion, who, when he was allied what was the principal thing in oratory, re¬ plied, A&ion ; and being allied again a fecond and a third time, what was next confiderable, be dill made the fame anfwer.” By which he feemed to intimate, that he thought the whole art did in a manner conflft in it. And indeed, if he had not judged this highly neceflary for an orator, he would fcarce have taken fo much pains in correcting thofe natural defeats, under which he laboured at fird, in-order to acquire it. For he had both a weak voice, and likewife an impedi¬ ment in his fpeech, fo that he could not pronounce di- ftinftly fome particular letters. The former of which defeCts he conquered, partly by fpeaking as loud as he could upon the (bore, when the fea roared and was boiderous ; and partly, by pronouncing long periods as he walked up-hill; both which methods contributed to the drengthening of his voice. And he found means to render his pronunciation more clear and ar¬ ticulate, by the help of fome little dones put under his tongue. Nor was he lefs careful in endeavouring to gain the habit of a becoming and decent gedure^ lor which gurpofe he ufed to pronounce his difeourfes alone before a large glafs. And becaufe he had got an ill cudom of drawing up his fhoulders when he fpoke ; to amend that, he ufed to place them under a fword, which hung over him with the point down¬ ward. Such pains did this prince of the Grecian ora¬ tors take to remove thofe difficulties, which would have been fufficient to difeourage an inferior and lefs afpiring genius. And to hot*’ great a perfection he arrived in his aCtion, under all thefe difadvantages, by his indefatigable diligence and application, is evident from the confeffion of his great adverfary, and rival in oratory, Efchines. “ Who, when he could not bear the difgrace of being worded by Demodhenes in the caufe of Ctefiphon, re¬ tired to Rhodes. And being defired by the inhabi¬ tants to recite to them his own oration upon that oc- cafion, which accordingly he did ; the next day they requeded of him to let them hear that of Demodhe¬ nes ; which having pronounced in a mod graceful man¬ ner, to the admiration of all who were prefent, “ How much more, (fays he,) would you have wondered, if you had heard him fpeak it himfelf!” By which he plainly gave Demodhenes the preference in that re- fped. We might add to thefe authorities the judg¬ ment of Quintilian, who fays, that “ it is not of fo much moment what our compofitions are, as how they are pronounced ; fince it is the manner of the deli¬ very, by which the audience is moved.” And there¬ fore he ventures to affert, that, “ an indifferent dif¬ eourfe, affided by a lively and graceful a&ion, will have greater efficacy than the fined harangue,, which wants that advantage.” The truth of this fentiment of the ancients, con¬ cerning the power and efficacy of pronunciation,, might be proved from many indances; but one or two may here fuffice. Hortenfius, a cotemporary with Cieero, and while living next to him in reputation aa; an orator, was highly applauded for his action. But his orations after his death, as Quintilian tells us (for we have none of them now remaining), did not appear anfwerable to his chana&er; from whence he judly concludes, there mud have been fomething pleafing when he fpoke, by which he gained his charafter, which was lod in reading them. But perhaps there is fcarce a more eonfiderable indance of this than in Cicero hitufelf. After the death of Pompey, when Csefair 5732 ORATORY. Part IV. Pronuncia- Catfar had got the government into his own hands, tlor1, many of his acquaintance interceded with him in be¬ half of their relations and friends, who had been of the contrary party in the late wars. Among others, Cicero folicited for his friend Ligarius; which Tubero underftanding, who owed Ligarius a grudge, he op- pofed it, and undertook to reprefent him to Ctefar as unworthy of his mercy. Casfar himfelf was prejudiced againft Ligarius; and therefore, when the caufe was to come before him, he faid, “ We may venture to hear Cicero difplayhis eloquence ; for I know the per- fon he pleads for to be an ill man, and my enemy.” But, however, in the courfe of his oration, Cicero fo worked upon his paffions, that by the frequent altera¬ tion of his countenance, the emotions of his mind were very confpicuous. And when he came to touch upon the battle of Pharfalia, which had given Caefar the empire of the world, he reprefented it in that moving and lively manner, that Caefar could no longer con¬ tain himfelf, but was thrown into fuch a fit of (hiver¬ ing, that he dropped the papers which he held in his hand. This was the more remarkable, becaufe Caefar was himfelf one of the greatell orators of that age, knew all the arts of addrefs, and avenues to the paf¬ fions, and confequently was better prepared to guard againft them. But neither his (kill, nor refolution of mind, was of fufficient force againft the power of ora¬ tory ; but the conqueror of the world became a con- queft to the charms of Cicero’s eloquence ; fo that, contrary to his intention, he gave into his plea, and pardoned Ligarius. Now that oration is dill extant, and appears exceedingly well calculated to touch the foft and tender pafiions, and fprings of the foul; but we believe it can fcarce be difcernible to any in reading it, how it (hould have had fo furprifing an effe& ; which mult therefore have been chiefly owing to the wonder¬ ful addrefs and condufl of the fpeaker. The more natural the pronunciation is, it will of confequence be the more moving, fince the perfeftion of art confifts in its neareft refemblance to nature. And therefore it is not without good reafon, that the ancients make it one qualification of an orator, that he be a good man ; becaufe a perfon of this chara&er will make the caufe he efpoufes his own, and the more fen- fibly he is touched with it himfelf, his aftion will be the more natural, and by that means the more eafily affeA others in the fame manner. Cicero, fpeaking up¬ on this fubjeft, fays : “ It is certain that truth (by which he means nature) in every thing excels imita¬ tion; but if that was fufficient of itfelf in a&ion, we fhould have no occafion for art.” In his opinion therefore (and who was ever a better judge ?) art in this cafe, as well as in many others, if well managed, will affift and improve nature. But that is not all; for fometimes we find the force of it fo great and power¬ ful, that, where it is wholly counterfeit, it will for the time work the fame effect as if it was founded in truth. This is well known to thofe who have been converfant with the reprefentations of the theatre. In tragedies, though we are fenfible that every thing we fee and hear is feigned and counterfeit, yet fuch is the powfer of a&ion, that we are oftentimes afFefted by it in the fame manner as if they were all realities. Anger and refentment at the appearance of cruelty, concern and folicitude for diftrefled virtue, rife in our breafts; and tears are extorted from us for opprefied innocence: Pronuncia though at the fame time, perhaps, we are ready to tion‘ laugh at ourfelves for being thus decoyed. If art then has fo great an influence upon us, when fupported on¬ ly by fancy and imagination; how powerful muft be the effeA of a juft and lively reprefentation of what we know to be true and real ? How agreeable it is both to nature and reafon, that a warmth of expreffion and vehemency of motion fhould rife in proportion to the importance of the fubjeft and concern of the fpeaker, will further ap¬ pear, by looking back a little into the more early and Ample ages of the world. For the higher we go, the more we (hall find of both. We (hall give the obferva- tion of a very great man upon this head, in his own words. “ The Romans (fays he) had a very great gr talent this way, and the Greeks a greater. The za-Eloquence^ ftern nations excelled in it, and particularly the He-p. jj. brews. Nothing can equal the (Length and vivacity of the figures they employed in their difcourfe; and the very actions they ufed to exprefs their fentiments; fuch as putting afhes on their heads, and tearing their garments, and covering themfelves with fackcloth un¬ der any deep diftrefs and forrow of mind. I do not fpeak of what the prophets did to give a more lively reprefentation of the things they foretold, becaufe fuch figurative actions were the effeft of divine infpi- ration. But even in other cafes we find thofe people underftood much better than we do how to exprefs their grief, and fear, and other palfions. And hence, no doubt, arofe thofe furprifing effefts of eloquence, which we never experience now.” Thus far this ex¬ cellent writer. And what he fays h^ere with refpedl to the a&ions of the eaftern nations, was in a good meafure cuftomary among the Greeks and Romans; if not entirely of the fame kind, yet perhaps as vehe¬ ment and expreflive. They did not think language of itfelf fufficient to exprefs the height of their paffions, unlefs enforced by uncommon motions and geftures. Thus, when Achilles had driven the Trojans into their city with the greateft precipitation and terror, and only Heitor ventured to tarry without the gates to engage him ; Homer reprefents both king Priam and his queen under the higheft confternation for the danger of their fon. And therefore, in order to pre¬ vail with him to come into the city, and not fight with Achilles, they not only intreat him from the walls in the moft tender and moving language imaginable ; but he tears off his grey locks with his hands; and (he in a flood of tears expofes her breafts, and adjures him by thofe paps which fuckled him, to comply with their requeft. The poet knew very well, that no words of themfelves could reprefent thofe agonies of mind he endeavoured to convey, unlefs heightened by the idea of fuch adtions as were expreffive of the deepeft for¬ row. And indeed this was anciently efteemed fo re- quifite in an orator, that in matters of importance he was fcarce thought to be in earned, who wanted it. In one of Cicero’s orations, he does not ftick to argue in that manner with his adverfary. “ Would you talk thus (fays he) if you was ferious ? Would you, who are wont to difplay your eloquence fo warmly in the danger of others, aft fo coldly in your own ? Where is that concern, that ardour, which ufed to extort pity even from children ? Here is no emotion either of mind I Part IV. ORA Rronuncia- or body ; neither the forehead ftruck, nor the thigh, 1,1 tlon- nor fo much as a ftamp of the foot. Therefore, you have been fo far from inflaming our minds, that you have fcarce kept us awake.” As a&ion therefore was judged fo neceflarya qua¬ lification in an orator among the ancients, fo they made ufe of feveral methods and expedients for the better attaining it. The principal of which we (hall briefly mention. Decency of pronunciation is an habit. And as all habits are gained by time, fo the fooner they are learned, they are generally acquired with greater eafe. For while perfons are young, they are not only more flexible, and capable of any particular bent, but they are likewife free from the trouble of encountering and fubduing contrary habits, which doubles the labour, and increafes the difficulty of attaining any laudable quality. Quintilian was very fenfible of this in the cafe here before us; and therefore, in order to have perfons trained up to it, he begins with them in their childhood, and defcends fo low as even to give direc¬ tions how they fliould be taught to pronounce when they firft learn to read. And he advifes, that they fhould then be inftrufted where to fufpend their voice, and make the proper paufes, both in diftinguifhing the feveral parts of the fame fentence, and in fepara- ting one fentence from another: likewife when to raife, or fink their voice, or give it a proper inflec¬ tion ; to be flower or fafter, more vehement or fedate, as the nature of the things may require ; and that the tone of their voice be always manly and grave, but at the fame time mixed with an agreeable fweetnefs. Thefe things may perhaps appear in themfelves fmall; but if duly attended to, they will be found of confi- derable fervice to bring us to a juft and proper pro¬ nunciation. For in every thing that is to be attain¬ ed by praftice, it is a great advantage to fet out right at firft. The ancients likewife had perfons, whom they call¬ ed phor.afci, whofe proper bufinefs it was to teach them how to regulate and manage their voice ; and others, who inftrufted them in the whole art of pro¬ nunciation, both as to their voice and geftures. Thefe latter were generally taken from the theatre, being fome eminent experienced adlors. So Quintilian, treating of the province of thefe perfons, fays: “ The comedian ought to teach them how to relate fafts, with what authority to advife, with what vehemence to exprefs anger, and with what foftnefs compaflion.” And fpeaking of geftures, he fays, “ He fhould ad- monifh them to raife their countenance, not diftort | their lips, or ftretch their mouths.” With feveral other direftions of the like kind. And we are told concerning the emperor M. Antoninus, ufually called the philofopher, that, Hh firji majierj ’were Euphoria the grammarian, and Geminus the comedian. But though they made ufe of aftors to inftruft their youth in forming their fpeech and geftures, yet the action of an orator was much different from that of the theatre. Cicero very plainly reprefents this di- ftinftion, in the words of Craffus, when, fpeaking of orators, he fays: “ The motions of the body ought to be fuited to the expreffions, not in a theatrical way, 'mimicking the words by particular gefticulations; but in a manner exprelfive of the general fenfe j with a fe- TORY. 5733 date and manly inflexion of the fides ; not taken from Prommcia- the ftage and aftors, but from the exercife of arms and the paleftra.” And Quintilian fays to the fame pur- pofe : “ Every gefture and motion of the comedians is not to be imitated, nor to the fame degree.” They thought the aftion of the theatre too light and extra¬ vagant for the imitation of an orator ; and therefore, though they employed aftors to inform young perfons in the firft rudiments, yet they afterwards fent to the paleftra, or fchools defigned on purpofe to teach them a decent and graceful management of their bodies. And fuch fchoole, as Quintilian informs us, were in ufe both among the Greeks and Romans : Juft as of later ages children learn to dance, in fome meafure with the fame intention. Being thus far prepared, they were afterwards fent to the fchools of the rhetoricians. And here, as their bufinefs was to cultivate their ftyle, and gain the whole art of eloquence ; fo particularly to acquire a juft and accurate pronunciation by thofe exercifes, in which for that end they were conftantly employed. And as the Greeks were moft celebrated for their ikiil in all the polite arts, and efpecially oratory ; the Ro¬ man gentry and nobility generally fent their fons abroad, and placed them under the tuition of fome Grecian matter, to inftruft them in the art of fpeak¬ ing, and by that means to fit them for the fervice of their country, either in the courts ofjudicature or the fenate. Thus Cicero was fent to Rhodes, to ftudy un¬ der the famous Molo, and Brutus under Pammenes; Casfar was going to the fame place when taken by pirates ; and Auguftus afterwards ftudied there under Apollodorus. Nor, after all this pains and induftry, did they yet think themfclves fufficiently qualified to take upon them the chara&er of orators. But it was their con- ftant cuftom to get together fome of their friends and acquaintance who were proper judges of fuch perform¬ ances, and declaim before them in private. The bufi- finefs of thefe perfons was to make obfervations both on their language and pronunciation. And they were allowed the greateft freedom to take notice of any thing they thought amifs, either as to inaccuracy of method, impropriety of ftyle, or indecency of their voice or aftions. This gave them an opportunity to correft any fuch defe&s at firft, before they became habitual. What effefts might not juftly be experfted from fuch an inftitution ? Perfons trained up in this manner, with all thofe advantages, joined to a good natural genius, could not fail of making very com¬ plete orators. Though even after they came to appear in public, they did not lay afide the cuftom of de¬ claiming. For Quintilian tells us, that C. Carlo ujed to praftife it daily in his tent. And Auguftus is re¬ ported to have continued it during the war of Mutina againft M. Anthony. Nor is it to be fuppofed, that fo conftantan attendance to this praftice was only fer- viceable to them in their public performances ; but it muft neceffarily affeft their whole conduft, give them a freedom of fpeech, eafinefs of addrefs and behaviour, and render them in all refpefts fine gentlemen, as well as excellent orators. And from hence perhaps we may fee lefs reafon to wonder at the furprifing effeft* of fome of their difeourfes, when we confider what pains they took to arrive at thofe abilities. Having 5734 ° ,R. A T Pronuncia- Having thus far treated on pronunciation in gene- tion- ral, we (hall now proceed to confider the parts of it feparately; which are, voice zaA gejiure. O R Y. Part IV Chap. II. Of the Voice. Voice is one kind of founds. Now the influence of founds, either to raife or allay our paffions, is evi¬ dent from mufic. And certainly the harmony of a fine difcourfe, well and gracefully pronounced, is as ca¬ pable to move us, if not in a way fo violent and ecfta-/ tic, yet no lefs powerful, and more agreeable to our rational faculties. As the bufinefs of this chapter is to offer fome confiderations for the juft and decent management of the voice, it may not be improper in the firft place to obferve in general, what nature does, when free and unconftrained. As perfons are different¬ ly affefted when they Tpeak; fo they naturally alter the tone of their voice, though they do not attend to it. It rifes, finks, and has various inflexions given it, according to the prefent ftate and difpofition of the mind. When the mind is calm and fedate, the voice chafms in fpeaking, than variations. Befides, as they Pronun often prevent the hearers from taking in the fenfe of t‘Qn* what is faid, it gives them no fmall uneafinefs that they are obliged to ftretch their attention. Many per¬ fons are too apt to be guilty of this, efpecially at the end of a fentence, by dropping the laft word; which ought in a particular manner to be expreffed diltinXly, becaufe the meaning of the whole fentence often de¬ pends upon it. The medium between thefe two is a moderate and even voice. But this is not the fame in all ; that which is moderate in one would be high in another. Every perfon therefore muft regulate it by the natural key of his own voice. A calm and fedate voice is general¬ ly beft ; as a moderate found is moft pleafing to the ear, if it be clear and diftind. But this equality of the voice muft alfo be accompanied with a variety, otherwtfe there can be no harmony ; fince all harmony confifts in variety. Nothing is lefs pleafing, than a dif¬ courfe pronounced throughout in one continued tone of the voice^ without any change or alteration. Be¬ ds moderate and even ; when the former is dejeXed fides, a variation of the voice is an cafe to the fpeaker ; with forrow, the latter is languid ; and when that is as the body is relieved by ftiifting its pofture. The inflamed by paflion, this is raifed and elevated. It is equality therefore we are here fpeaking of, admits a the orator’s bufinefs, therefore, to follow nature, and variety of inflexions and changes within the fame to endeavour that the tone of his voice appear natu- pitch. And when that is altered, the gradations, ral and unaffeXed. And for this end, he muft take whether higher or lower, fhould be fo gentle and re¬ care to fuit it to the nature of the fubjeX ; but ftill fo gular, as to preferve a due proportion of the parts, and as to be always grave and decent. Some perfons con- harmony of the whole; which cannot be done, when tinue a difcourfe in fuch a low and drawling manner, the voice is fuddenly varied with too great a diftinc- that they can fcarce be heard by their audience. O- tion. And therefore it fhould move from one key to thers again hurry on in fo loud and boifterous a man- another, fo as rather to glide like a gentle ftream, ner as if they imagined their bearers were deaf. But than pour down like a rapid torrent,^.as an ingenious all the mufic and harmony of fpeech lies in the proper writer has well expreffed it. An even voice is beft fit- temperament of the voice between thefe extremes. In ted to keep the mind to clofe attention. And there- order to fet this matter in a juft light, it will be ne- fore, in fubjeXs defigned only for inftruXion, without ceffary to confider the principal affeXions or proper- any addrefs to the paffions, there is little room for a ties of the voice, and how they are to be regulated by variety of voice. For the voice ought to agree with a orator. Now thefe may all be referred either to quantity or quality. The quantity of the voice confifts in its highnefs or lo’wnefsy fuiftnefs or Jlo’wnefs, and the intermediate degrees between them. Every perfon who fpeaks in public, fhould endea¬ vour, if he can, to fill the place where he fpeaks. But ftill he ought to be careful not to exceed the natural key of his voice. If he does, it will neither be foft nor agreeable ; but either harfh and rough, or too ftirill and fqueaking. Befides, he will not be able to give every fyllable its full and dittinX found ; which will render what he fays obfeure, and difficult to be underftood. He fhould therefore take -care to keep his voice within reach, fo as to have it under manage¬ ment, that he may raife or fink it, or give it any in¬ the ftyle ; and as upoh fuch fubjeXs this ffiould be equal, moderate, and fmooth, fo fhould the other. E- very thing, as we fay, is beautiful in its feafon; and there is a certain propriety in things, which ought al¬ ways to be regarded. And therefore, an affeXed va¬ riety, ill placed, is as difagreeable to a judicious au¬ dience, as the want of it, where the fubjeX requires it. We may find fomC perfons, in pronouncing a grave and plain difcourfe, affeX as many different tones, changes, and variations of their voice, as if they were aXing a comedy ; which is doubtlefs a very great impropriety. But the orator’s province is not barely to apply to the mind, but likewife to the paffions ; which require a great variety of the voice, high or low, vehement or languid, according to the nature of the paffions hede- figns to affeX. So that for an orator always to ufe ficXion he thinks proper: Which it will not be in his the fame tone or degree of his voice, and expeX to power to do, if he put a force upon it, and ftrain it beyond its natural tone. The like caution is to be ufed againft the contrary extreme, that the voice'be not dropped, and fuffered to fink too low. This will give the fpeaker pain in railing it again to its proper pitch, and be no lefs of- fenlive to the hearers. For though the mufic of fpeech confiils in the variations of the voice, yet they muft be gradual to render them pleafant. Such fudden and great changes at once are rather to be efteemed anfwer all his views by it; would be much the fame thing as if a phyfician fhould propofe to cure all di- ftempers by one medicine. From hence it is evi¬ dent, that although various inflexions and tones of the voice are requifite to make it harmonious and plea¬ fing to the ear; yet the degree of it fhould differ ac¬ cording to the nature of the fubjeX and defign of the fpeaker. And, as a pcrftX monotony is al¬ ways unpleafant, fo it can never be neceffary in any difcouife. The Part IV. O R A 1 Pranuncia- The next property of the voice above-mentioned tion- wasfwiftntfs. That fome exprefiions ought to be pronounced fafter and Pwifter than others, is very ma- nifeft. Gay and fprightly ideas (hould not only be expreffed louder, but alfo falter, than fuch as are fad and melancholy. And when we prefs an adverfary, the voice Ihould be bride and quick. But to hurry on in a precipitant manner without paufing, till ftopt for want of breath, is certainly a very great fault. This deltroys not only the necefla-ry diftindtion between fen- tence and fentence, but likewife between the feveral words of the fame fentence ; nay, and often occafions us to exprefs our words by halves, while one is thrown fo fad upon another, that we are not able to give each its full and juft found. By this means all the grace of fpeaking is loft, and in a great meafure the advantage of hearing. For when the ears of the hearers cannot keep pace with the volubility of the fpeaker’s tongue, they will be little the better for what he fays. Befides, by not commanding his voice, ' and eafing his breath at the proper paufes and points of diitinftion.he is often obliged to flop in the middle of a fentence; and fo divides what fhonld be conti¬ nued, and joins what fhould be feparated; which muft neceflarily deftroy the fenfe, and confound his difeourfe. Young perfons are very liable to this, efpe- . daily at firft felting out. And it often arifes from diffidence. They are jealous of their performances, and the fuccefs they may have In fpeaking, which gives them a pain till it is over; and this puts them into a hurry of mind, which incapacitates them from governing their voice, and keeping it under that due regulation which perhaps they propofed to them- felves before they began to fpeak. And the greater degree fuch perfons have of a native and ingenuous modefty, accompanied w-ith a laudable ambition to excel, they are commonly more expofed to this. For while on the one hand they are fired with an ardent defire to recommend themfelves, and on the other are fearful of the event, this dubious ftate of mind is very apt to throw them off their guard, and run them into this excefs. From which we may fee the great advan¬ tage of having the voice well formed betimes ; for when once it is become habitual to fpeak with juftnefs and propriety, perfons readily pradtife it without much at¬ tention or concern. And as a precipitant and hafty pronunciation is culpable, fo likewife on the other hand, it is-a fault to fpeak too flow. This feems to argue a heavinefs in the fpeaker. And as he appears cool himfelf, he can never expedl to warm his hearers, and excite their af¬ fections. When not only every word, but every fyl- lable is drawn out to too great a length, the ideas do not come faft enough to keep up the attention without much uneafinefs. For till the fenfe is completed, the mind is in fufpence ; and, if it be held long in that fi- tuation, it will of courfe flag and grow tired. In¬ deed, in fome cafes, it is reqmifite the pronunciation fhould be flower than in others ; as in reprefenting things great and difficult; or in expreffing fome par¬ ticular paffions, as admiration or grief. But the ex¬ treme we are now fpeaking of, is a flownefs equally continued through an whole difeourfe, which muft ne- ceffarily render it flat and lifelefs. Now, to avoid either of the two extremes laft men- Vou. VIII, a 'OR Y. 5735 tioned, the voice ought to be fedate and diftinft. Prommcu- And in order to render it diftindl, it is neceffary, not t,on' only that each word and fyRablt fliould have its juft and full found, both as to time and accent; hut like¬ wife that every fentence, and part of a fentence, Ihould be feparated by its proper paufe and interval. This is more eafy to be done in reading, from the af- flftance of the points ; but it is no lefs to be attended to in fpeaking, if we would pronounce in a diftindt and graceful manner. For every one ftiould fpeak in the fame manner as he ought to read, if he could ar¬ rive at that exadtnefs. Now the common rule given in paufing is, that we flop our voice at a comma till we can tell one, at a femicolon two, at a colon three, and at a full period four. And as thefe points are either accommodated to the feveral parts of the fame fentence, as the firft three ; or different fentences, as the laft ; this pccafions the different length of the paufe, by which either the dependance of what pre¬ cedes upon that which follows, or its diftindlion from it, is reprefented. And therefore, in the firft three flops, the voice is rather to be fufpended in different degrees or meafures of time, than entirely dropt, to fhew that the fenfe is not yet completed. But between fentence and fentence we refpire, and begin anew. So that in long periods, the voice fhould be favoured by beginning low and fedately, that it may hold to the end without refpiration ; or if it will not, the breath ought to be recovered without finking the voice. For if once the voice drop for want of breath before the period be finifhed, not only the beauty, but likewife the fenfe of it will be loft. Quintilian lays a great ftrefs upon a due attention to thefe paufes ; and fays, “ Though it may appear not fu confidterable in* itfelf, yet all the other virtues of a good pronounewtion are deficient without it.'’ Hitherto we have confidered1 fuch properties of the voice as refpeft quantity, we come n nv to fpeak of its qualities. And the chief of thefe are- Jfren^th or weaknefr, clearnefs or obfeuremfs, fulntfs or fmallnefs, fmoothnefs or roiighnefs. Now, one half of thefe is what every one would willingly ehoofe, as he would wifh to be free from the others. But it is not in our power to give ourfelves what qualities of the voice we pleafe ; but only to make the- heft ufe we can of what nature has beftowed upon- us. However, feveral de¬ feats of the voice are capable of being helped by care and proper means; as, on the other hand, the heft voice may be greatly hurt by ill management and in- diferetion. Temperance is a great prefervative of the voice, and all excefs is highly prejudicial to it. The voice muft neceffarily funer, if the organs of fpeecli have not their proper tone. And in order to their having this, they muft be kept in a due temperature ; that is, they muft neither be too moift nor too dry. If they abound with fluidt-, thefe will qbftruift the clearnefs of the voice, and render it obfetrre and con- fufed ; and if they are parched with drought, the voice will be harfti and rough. Now all exceffes, as well as fome bodily indifpofitions, are apt to affeft the or¬ gans one or other of thefe ways. A ftrong voice is very ferviceabl'e to an orator, be- caufe, if it want fome other advantages, he is, how¬ ever, capable to make himfelf heard. And if at any time he is forced to drain it, he is in lefs danger of its 32 K fail- S7S6 Pronuncia ORATORY. PartIV. failing hinfi before he has finiflied his difcourfe. But he who has a weak voice, (hould be very care¬ ful not to drain it, efpecially at firft. He ought to begin low, and rife gradually to fuch a pitch as the key of his voice will well carry him, without being obliged to fink again afterwards. Frequent in¬ flexions of the voice will likewife be.fome afMance to him. But efpecially he fhould take care to fpeak deliberately, and eafe his voice, by allowing due time for refpiration at all the proper paufes. It is an ex¬ treme much, lefs inconvenient for fuch a perfon rather to fpeak too flow, than too fall. But this defeX of a weak voice is fometimes capable of being helped, by the ufe of proper methods ; as is evident from thein- ftance of Demofthenes, before-mentioned. A voice is faid to be clear, when the organs of fpeech are fuited to give every Angle letter, and all the combinations of them in fyllables and words, their proper and diftinX found. Such a voice is very pleafing and agreeable to the hearers; and no lefs an happinefs to the fpeaker, as it faves him a great ex¬ pence of fpirits. For a moderate voice, if clear, will be as diftinXly heard, as one much louder, if thick and obfcure. Which is a great advantage to the fpeaker, becaufe he can better keep his voice under command, and modulate it at pleafure, as the feveral parts and circumftances of his difcourfe may require. On the contrary, an obfcure and confufed voice is not always occafioned from a deficiency in the organ; but, many times, is the effeX of cuftom and a bad habit. Some perfons, either from want of due care in their education at firft, or from inadvertency and ne¬ gligence afterwards, run into a very irregular and confufed manner of expreffing their words ; either by raifplacing the accent, confounding the found of the letters, or huddling the fyllables one upon another, fo as to render what they fay often unintelligible. In¬ deed, fometimes this arifes from a natural defeX, as in the cafe of Demofthenes; who found a method to reXify that, as well as the weaknefs of his voice. But in faults of this kind, which proceed from habit, doubtlefsthe moft likely way to mend them is to fpeak deliberately. A full voice is not the fame, as a ftrong, nor a loud voice. It fills the ear, but it is often not pjea- fant. And therefore to render it fo,. as well as audible, it fhould be frequently varied. However, this feems better fuited to the charaXer of an orator, than a Tmall and. (hrill voice becaufe it has fomething in it more grave and manly. And thofe, who have the misfortune of a very fmall voice, fhould be cautious of railing it to too high a pitch, efpecially at once; be¬ caufe the fudden comprdfure of the organ, is apt to occafion a fqueaking and very difagreeable found.. A foft and fmooth voice is of all the moft mufical, efpecially if it be flexible. And on the contrary, nothing is lefs harmonious than a voice that is harfh and rough. For the one grates as difagree- ably upon the ear, as the other gives it pleafure and delight. From the confideration of thefe feveral properties of the voice, we may conclude that to be the belt, and fitted for an orator, which is moderate, diftinX, firm, clear, and fmootb, and withal eafily flexible to tfije, feveral degrees and variations, af found which every part of the difcourfe may require. Pronuncia* Chap. III. Of Gefiure. — By this is meant, a fuitable conformity of the mo- tions of the countenance, and feveral parts of the body in fpeaking, to the fubjeX-matter of the difcourfe. The word gejlure is here ufed in a larger fenfe than is ordinarily done in common language. For we rarely make ufe of that word to denote the motions of the counienance, or any parts of it ; but as thefe make a confiderable part of our prefent fubjeX, they mud here be comprehended under this term. It is not agreed among the learned, whether voice or gefture has the greater influence upon us. But as the latter affeXs us by the eye, as the former does by the ear, gefture in the nature of it feems to have this advantage, that it conveys the impreffion more fpeedi- ly to the mind ; for the fight is the quickeft of all our fenfes. Nor is its influence lefs upon our pafiions; nay, in fome inftances it appears to aX more power*' fully. A call of the eye fhall exprefs defire in as mo¬ ving a manner, as the fofteft language; and a diffe¬ rent motion of it, refentment. To wring the hands, tear the hair, or ftrike the bread, are all ftrong indica¬ tions of forrow. And he who claps his hand to his fword, throws us into a greater panic than one who only threatens to kill us. Nor is it in fome refpeXs lefs various and extenfive than language. Cicero tells us, he often diverted himfelf by trying this with Rofcius the comedian; who could exprefs a fentence as many ways by his geftures, as he himfelf by words. And fome dramas have been carried on wholly by mutes, who have performed every part by geftures only, without words, in a way very intelligent, as well as entertaining to the fpeXators. Well therefore might Cicero call attion (or gefture) the language of the body, fince it is capable in fo lively a manner to convey both our ideas and pafiions. But with refpeX to oratory, gefture may very properly be called the fecond part of pronounciation ; in which, as the voice fhould be fuited to the imprefiions it receives from the mind, fo the feveral motions of the body ought to be accommodated to the various tones and inflexions of the voice. When the voice is even and moderate, little gefture is required ; and nothing is more unna¬ tural than violent motion, in difeourfing upon ordi¬ nary and familiar fubjeXs. The motions of the body fhould rife therefore in proportion to the vehemence and energy of the expreffton, as the natural and genuine effeX of it. But as gefture is very different and various as to the manner of it, which depends upon the decent con- duX of feveral parts of the body ; it will not be amifs to confider more particularly, the proper manage¬ ment of each of thofe parts. Now all gefture is either natural, or from imitation. By natural gefture we mean fuch aXions and motions of the body, as na¬ turally accompany our words, as thefe do the im- prtfiions of our minds. And thefe either refpeX the whole body, or fome particular part of it. But be¬ fore we enter upon this, give us leave juft to obferve, that it has been cuftomary in all ages and countries, in making a fet difcourfe before an aflembly, to do it (landing. Thus we read, that, Abraham food upr andfpake unto the children of Heth. And it feems.as Part IV. ORA’ Pionuncia- jf he fat down, when he had ended his fpeech ; be- ri00, caufe, immediately after the account of their anfwer, it is faid again, that Abraham Jlodd up and bowed him* felf to the people of the land, the children of Heth. In like manner Homer reprefents the Grecian princes, as ftanding up, when they made a fpeech, either to the army, or in their councils. So when Achilles has affembled the army, to inquire into the reafon of the reat plague which at that time raged among them, e rifes up before he begins to fpeak, and fits down again when he has done. After him the prophet Calchas rifes, and charges it upon Agamemnon ; who rifing up in a pafiion, does not refufe to comply with what Calchas propofed, but expreffes his refentment at him for faying it. And upon another occafion, both Agamemnon and Neftor do the fame in council. And Cicero acquaints us, that when Lentulus had been charged in the fenate, as an affociate with Ca¬ tiline, he flood up to make his defence. Nor does the advantage of being better heard, feem to have been the only reafon for fo general an agreement in this pofture; but it appears likewife to have been chofen, as the moft decent and refpe&ful. Sitting carries in it an air of authority, and is therefore a pofture fcarce ufed upon fuch occafions, unlefs perhaps where that is defigned to be exprefled by it. Where¬ fore it was a thing very much relented, that when Csefar, after he had got the power into his hands, be¬ ing once addrefled to the fenate, either refufed to rife, as fome fay, or as others, one of his friends held him down by his gown. But though ftanding appears to be the moft proper pofture for fpeaking in public, yet it is very unbe¬ coming for the body to be entirely without any mo¬ tion like a ftatue. It (hould not long continue in the fame pofition, but be conftantly changing, though the motion be very moderate. There ought to be no appearance of ftiffnefs, but a certain eafe and pliable- nefs, naturally fuiting itfelf to every expreflion ; by which means, when a greater degree of motion is neceflary, it will appear lefs fudden and vehement. For as the raifing, finking, and various infleftions of the voice mull be gradual; fo likewife fhould the mo¬ tions of the body. It is only on fome particular oc¬ cafions, that an hafty vehemence and impetuofity is pro¬ per in either cafe. As to the feveral parts of the body, the head is the moft confiderable. To lift it up too high has the air of arrogance and pride; to ftretch it out too far, or throw it back, looks clownilh and unmannerly; to hang it downwards on the breaft, (hews an unmanly balhfulnefs, and want of fpirit; and to fuffer it-to lean on either ftioulder, argues both floth and indolence. Wherefore in calm and fedate difeourfe it ought to keepfts natural ftate, an upright pofture. However, it Ihould not be long without motion, nor yet always moving ; but gently turn fometimes on one fide, and fometimes on the other, as occafions. requires, that the voice may be heard by all who are prefent; and then re¬ turn again to its natural pofition. It Ihould always accompany the other aftions of the body, and turn on the fame fide with them ; except when averfion to any thing is expreft, which is done by ftretching out the right hand, and turning the head to the left. The ancients ere&ed a ftatue of Venus in this pofture, who r O R Y. 5737 was called by the Greeks and by the LatinsProruncia- Verticordia, and in Englilh may be termed the forbid- 1,'t^on'. ding Venus. But nothing is more indecent, than violent motions and agitations of the head. And therefore, when a witty writer, who is well known among us, would convey the moft ridiculous idea of a pretender to knowledge, he exprefles it thus : For having three times (hook his head To ftir his wit up, thus he faid. Hudib. But it is the countenance, that chiefly reprefents both the paffions, and difpofition of the mind. By this wc exprefs love, hatred ; joy, forrow; modefty, and con¬ fidence : by this we fupplicate, threaten, footh, in¬ vite, forbid, confent, or refufe ; and all this without fpeaking. Nay, from hence we form a judgment not only of a perfon’s prefent temper, but of his capacity and natural difpofition. And therefore it is common to fay, fuch an one has a promifing countenance, or that he promifes little by his countenance. It is true, this is no certain rule of judging ; nor is it in the power of any one to alter the natural make of his countenance : however, it may put us upon endeavouring to gain the moft plealing afpeft we can ; fince it is fo natural for mankind to draw fuch conclufions from it; and fome perfons are fo unhappy, as to render their coun¬ tenance more difagreeable, than otherwife it wouldbe, by ill habits. But the feveral parts of the face bear their part, and contribute to the proper and decent motion of the whole. In a calm and fedate difeourfe, all the features retain their natural ftate and fituation. In forrow, the forehead and eyebrows lour, and the cheeks hang down. But in expreflions of joy and chearfulnefs, the forehead and eyebrows are expanded, the cheeks contra&ed, and the corners of the mouth drawn up¬ wards. Anger and refentment contraft the forehead, draw the brows together, and thruft out the lips. And terror elevates both the brows and forehead. As thefe are the natural figns of fuch paflions, the orator Ihould endeavour to conform to them. But as the eyes are moft a&ive and fignincant, it is the advice of Cicero that the greateft care fhould be taken in their management. And he gives this reafon for it, “ Becaufe other parts of the countenance have but few motions; whereas all the paffions of the foul are exprefled in the eyes, by fo many different aftions, which cannot poffibly be reprefented by any geftures of the body, if the eyes are kept in a fixed pofture.” Common experience does in a great mea- fure confirm the truth of this obfervation. We rea¬ dily guefs at a perfon’s intention^or how he is affe&ed to us, by his eyes. And any fudden change or emo¬ tion of the mind is prefently followed by an alteration in the look. In fpeaking therefore upon pleafant and delightful fubjeds, the eyes are brifk and chear- ful; as, on the contrary, they fink and are languid in delivering any thing melancholy and forrowful. This is fo agreeable to nature, that before a perfon fpeaks, we are prepared with the expectation of one or the other from his different afped. So likewife in anger, a certain vehemence and intenfenefs appears in the eyes, which, for want of proper words to exprefs it by, we endeavour to reprefent by metaphors taken from fire, the moft violent and rapid element, and fay in fuch cafes, ..the eyes fparkle, burn, or are inflamed: 32 K z la 5738 O R A 1 Pronuncia- In expreffions of hatred or deteftation, it is natural to tlon* alter the look, either by turning the eyes afide, or downwards. Virgil has very juftly obferved this: for when he defcribes iEneas meeting with Dido in the Elyfian fhades and addreffing her, he reprefents her difregard of him, by faying, Difdainfully (he look’d; then turning round. Still fix’d her eyes untnov’d upon the ground. She fliewed her refentment for his former treatment of her, by not vouchfafing to lookon him. Indeed, the eyes are fometimes turned downwards upon other occafions, as to exprefs modefty. -And if at any time a parti¬ cular object be addreffed to, whatever it be, the eyes fhould be turned that way. And therefore Philo- ftratus very defervedly ridicules a certain rhetorician as guilty of a folecifm in gefture, who, upon faying, 0 Jupiter! turned his eyes downward; and when he faid, 0 earth! looked upward. A flaring look has the appearance of giddinefs and w'ant of thought; and to contraft the eyes, gives fufpicion of craft and de- fign. A fixed look may be occafioned from intenfe- nefs of thought, but at the fame time (hews a difre¬ gard to the audience; and a too quick and wandering motion of the eyes denotes levity and vvantonnefs. A gentle and moderate motion of the eyes is therefore in common mod fuitable, always directed to fome of the audience, and gradually turning from fide to fide with an air of refpefl and modedy, and looking them de¬ cently in the face, as in common difcourfe: Such a behaviour will of courfe draw an attention. As in converfation, when a perfon addrefles us in an hand- fome and becoming manner, we prefently put ourfelves in a podure to give what he fays a proper reception. But as all the paffions are in the mod lively manner expreffcd in the eyes, their motions ought to vary ac¬ cording to the different nature of thole paffions they are fuited both to difcover in the fpeaker, and convey to his hearers:; fince, as the quicked accefs to the mind is by the fight, a proper well-timed look will fometimes fooner effed this than it can be done by words; as in difcharging a cannon, we are druck with the light before we hear the found. As to the other .parts of the body didinft from the head, .the (boulders ought not to be elevated; for this is. not only in itfelf indecent, hut it likewife contradts the neck, and hinders the proper motion of the head. Nor, on the other hand, fhould they be drawn down, and deprcfled; becaufe this occafions a diffnefs both’* to the neck and the whole body. Their natural podure therefore is bed, as being modeafyand grace¬ ful. To (hrug the fhoulders has an abjedt and fervile air; and frequently to heave them upwards and down¬ wards is a very difagreeable fight. A continued motion of the arms any way, is by all means to be avoided. Their adtion fhould generally be very moderate, and follow that of the hands, unlefs in very pathetic expreffions, where it may be proper to give them a more lively fpring. The hands need never be idle. Quintilian feems to think them as neceflary and powerful in adtion, as Cicerp does the eyes. “ The hands (fays he) without which all gedure is lame and weak, have a greater variety pf motions than can well be exprefled; for they are almoft equal to our words. Do not we defire with them, promife, call, difmifs, threaten, befeech, ' O R Y. PartIV. deteft, fear, inquire, deny? Do not they exprefs joy, Pmnuncia- forrow, doubt, confeffion, penitence, meafure, plenty, number, and time ? Do not they excite, redrain, prove, admire, and fhame? That in fo great a variety of fpeech among all nations and countries, this feems to me the common language of all mankind.” Thus far Quintilian. Now, all bodily motion is either up¬ ward or downward, to the right or left, forward or backward, or elfe circular. The hands are employed by the orator in all thefe, except the lad. And as they ought to correfpond with our expreffions, fo they ought to begin and end with them. In admiration, and addrefles to heaven, they mud be elevated, but never raifed above the eyes; and in fpeaking of things below us, they are direfted downwards. Side motion fhould generally begin from the left,andterminategently on the right. In demondrating, addreffing, and on feveral other occafions, they are moved forward; and in threatening, fometimes thrown back. But when the orator fpeaks of himfelf, his right-hand (hould be gently laid on his bread. When no other motion is necefiary, the hands fhould be kept about as high as the bread, fo as to make near a right angle with the arm. This is not only graceful# but likewife the mod eafy podure, and gives the lead drain to the mufcles. They (hould never be differed to hang down, nor to loll upon the cudiion or bar. The left hand (hould never move alone, but accommodate itfelf to the mo¬ tions of the right. In motions to the left fide, the right hand (hould not be carried beyond the left (houlder. In promifes, and expreffions of compliment, the motion of the hands (hould be gentle and flow; but in exhortations and applaufe more; fwift. The hands (hould generally be open; but in expreffions of compunftion and anger they may be clofed. All finical and trifling a&ions of the fingers ought to be avoided; nor (hould they be ftretched out and ex¬ panded in a ftiff and rigid pofture, but kept eafy and pliable. Neither the bread nor the belly (hould be thruft out: which in itfelf looks ungainly, and hinders the free motion of the trunk; which ought not to be kept too ftiff and upright, but eafy and flexible, always fuiting itfelf to the motions of the head and hands. The feet fhould continue fteady, and not give the body a wa¬ vering and giddy motion by frequently (hifting; tho* fome perfons fall into that habit without moving their feet. Curio, a Roman orator, as Cicero tells us, was addifted to this ; which occafioned a friend of his once to pafs a joke upon him, by afleing, Who that 'was talking out of a boat? The jeft is too plain to need explication; for every one knows the waving of a boat will give the body fuch a motion. The geftures we have hitherto difeourfed of, are fuch as naturally accompany our ex;preffions. And we believe thofe we have mentioned, if duly attended to, will be found fufficient to anfwer all the purpofes of our modern pronunciation. The ancients, indeed, ufed feveral more vehement a&ions and geftures than we are accuftomed to; as we have formerly (hewn. Philip the Roman orator, as Cicero informs us, did not ufe to prepare his difeourfes; but fpoke, as we fay, off¬ hand. And he was wont to tell'his friends, “ he was never fit to talk till he had warmed his arm.” He doubtlefc, therefore, ufe£ a more violent motion with PartIV. ORATORY. onuncia- his arms and hands than is common with us. And tion‘ Cicero cails the arm proje&ed the orator's 'weapon. Indeed, to extend or brandifh the arm, carries in it an air of command and authority, which was not unbeco¬ ming the charafter of Philip, who was a perfon of the higheft rank and quality. And therefore young orators, both among the Greeks and Romans, for a time ufed no motion of the arm, but kept it confined in their garment, as an argument of modefty, till age and ex¬ perience allowed them to ufe greater freedom. Nor was it uncommon for the ancient orators to exprefs the excefs of their pafiions by tears. They thought nothing unbecoming that was natural; and judged it agreeable to the charafters even of the braveft men, to be touched with a fenfe of humanity in great cala¬ mities: And therefore we find both Homer and Vir¬ gil make their greateft. heroes Ihed tears on fome oc- cafions. The other fort of geftures abovementioned are fuch as arife from imitation; as where the orator defcribes fome a&ion, or perfonates another fpeaking. But here great care is to be taken not to over-aft his P. part, by running into any ludicrous or theatrical mi¬ micry. It is fufficient for him fo to reprefent things of this nature, as may beft convey the image of them in a lively manner to the minds of the hearers; with¬ out any fuch change either of his aftions or voice as are not fuitable to his own charafter. Chap. IV. Some particular rules for the Voice and Gefture. ..j The fubjeft of pronunciation is of fo great impor¬ tance to an orator, that it can neither be too clearly laid down, nor too ftrongly inculcated. If we inquire into the caufes of that furprifing power it has over us, and by what means it fo ftrongly alfefts us, this may ,in fome meafure appear by reflefting on the frame and conftitution of human nature. For our infinitely great and wife Maker has fo formed us, that not only the aftions of the body are fubjeft to the direftion of the mind; but we are likewife endowed with various pafiions and affeftions, that excite us to purfue thofe things which make for our happinefs, and avoid others which are hurtful to us. And as we are made for fociety, we are alfo furnifhed with fpeech, which en¬ ables us to converfe one with another. And fuch is the contrivance of our make, and influence of our minds upon the mechanifm of our bodies, that we can not only communicate our thoughts to each other, but likewife our pafiions. For, as Cicero well ob- ferves, “ Every motion of the mind has naturally its peculiar countenance, voice, and gefture; and the whole body, every pofition of the face, and found of the voice, like the firings of an inftrument, aft agree¬ ably to the imprefiion they receive from the mind.” Nor is this all: but as every one is differently affefted himfelf, he is capable to make the like imprefiions upon others, and excite them to the fame motions which he feels in himfelf. As when two inftruments are fet to the fame pitch, the firings of the one being touched, produce in the other the like found. This common fympathyin the human frame /hews hownecef- fary it is that an orator fhould not only ingeneral be well acquainted with the rules of pronunciation, but like¬ wife know how to ufe them as occasion requires. For a general knowledge of the rules of art is not of itfelf P fufficient to perfeft an artift, without a further ac- _ quaintance with the particular application of them to their feveral cafes and circumftances. Thus, for in- ftance, it is not enough for an orator to underftand all the beauties and ornaments of language, and which of them are fuited to form the feveral kinds of ftyle; unlefs he can likewife accommodate each of thofe charafters to their proper fubjeft. And fo likewtfe in pronunciation, he ought not only to know the fe¬ veral qualities of the voice, and proper geftures of the body; but alfo when and where to make ufe of them. For not only different fubjefts, but alfo different parts of the fame difcourfe, and even particular expreflions, often require a difference in the manner of pronuncia¬ tion, both as to the voice and gefture. Having there¬ fore treated on both thefe parts of pronunciation in general, it may not be amifs now to confider, how they are to be applied in each of the two refpefts laft mentioned. We (hall begin with the parts of a difcourfe, and treat of them in their natural order. And here the view and defign of the fpeaker in each of them will eafily help us to fee the proper manner of pronuncia¬ tion. Let us fuppofe then a perfon prefenting himfelf be¬ fore an aflembly, in order to make a difcourfe to them. It cannot be decent immediately to begin to fpeak fo foon as ever he makes his appearance. He will firft fettle himfelf, compofe his countenance, and take a refpeftful view of his audience. This prepares them for filence and attention. To begin prefently, and hurry on, without firll allowing either himfelf or his hearers time to compofe themfelves, looks as if he was rather performing a talk, than had any defign to pleafe them; which will be very apt to make them as uneafy till he has done, as he feems to be himfelf. Perfons commonly form fome opinion of a fpeaker from their firft view of him; which prejudices them either in his favour, or otherwife, as to what he fays afterwards. A grave and fedate afpeft inclines them to think him ferious; that he has confidered his fubjeft, and may have fomething to offer worth their attention. A haughty and forbidding air occafions diftafte, as it looks like difrefpeft. A wandering giddy counte¬ nance argues levity. A dejefted drooping appearance is apt to raife contempt, unlels where the fubjeft is melancholy. And a chearful afpeft is a proper pre¬ lude to a pleafant and agreeable argument. To fpeak low at firft has the appearance of mo¬ defty, and is beft for the voice; which, by rifing gra¬ dually, will with more eafe be carried to any pitch that may be afterwards neceffary, without draining it. However, fome variation of the voice is always proper to give it an harmony. Nay, and fometimes it is not improper for an orator to fet out with a confiderabte degree of warmth, expreffed by fuch an elevation of the voice, and geftures of the body, as are fuited to reprefent the emotions of his mind. But this is not ordinarily the cafe. We have fome few inftances of this in Cicero; as in his oration for ,R°fc'us-Arner'm,s» where the heinoufnefs of the charge could not but ex¬ cite his indignation againft the accufers. And fo likewife in that againft Pifo, and the two firft againfl Catiline, which begin in the fame manner, frpm the refentment 5739 ronnneia- 574° O R A T Pronuncia- refentment he had conceived againfl. their perfons and tl0n‘ conduft. In the narration, the voice ought to be railed to foraewhat an higher pitch. Matters of faft ftiould be related in a very plain and diflindl manner, with a proper ftrefs and emphafis laid upon each circum- ftance, accompanied with a fuitable addrefs and mo¬ tions of the body, to engage the attention of the hearers. For there is a certain grace in telling a ftory, by which thofe who are matters of it feldom fail to recommend themfelves in converfation. The beauty of it confifts in an eafy and familiar manner of ex- preflion, attended with fuch adlions and geftures as are fuited to the nature of the things related, and help to enliven each particular circumftance and part of the difcourfe. The propofition, or fubjeft of the difcourfe, fhould be delivered with a very clear and audible voice. For if this be not plainly heard, all that follows in proof of it cannot well be underftood. And for the fame reafon, if it be divided into feveral parts or branches, they fhould each.be exprefled very deliberately and di- ftinftly. But as the defign here is only information, there can be little room for gefture. The confirmation admits of great variety, both of the voice and geftures. In reafoning, the voice is quick and pungent, and Ihould be enforced with fuit¬ able adtions. And as defcriptions likewife have often a place here, in painting out the images of things, the orator fhould fo endeavour to adapt both his voice, and the motions of his body, particularly the turn of bis eyes, and adtion of his hands, as may beft help the imagination of his hearers. Where he introduces another perfon fpeaking, or addreffes to an abfent perfon, it fhould be with fome degree of imitation. And in dialogue the voice fhould alter with the parts. When he diverts from his fubjedl by any digreF fion, his voice fhould be lively and chearful; fince that is rather defigned for entertainment than inftruc- tion. In confutation, the arguments of the adverfe party ought firft to be repeated in a plain and diftindf man¬ ner, that the fpeaker may not feem to conceal, or avoid the force of them. Unlefs they appear trifling and unworthy of a ferious anfwer; and then a face¬ tious manner, both of expreflion and gefture, may be 0IM |‘ a fenfe of the fpeaker’s opinion of the goodnefs of his jf caufe, and that he has offered nothing but what is agreeable to reafon and truth ; as likewife from his af- furancc that the audience agree with him in the fame Jl fentiments. In every undertaking that requires care ] and thought, perfons are apt at firft to be fedate and !| moderate; but when it is drawn to an end, and is near finifhed, it is very natural to appear more gay. If an enumeration of the principal arguments of the difcourfe be convenient, as it fometimes is, where they are pretty numerous, or the difcourfe is long; they ought to be expreffed in the moft clear j) and forcible manner. And if there be an addrefs to the pafiions, both the voice and gefture muft be fuit¬ ed to the nature of them, of which more will be faid prefently. We proceed now to the confideration of particular 1 expreffions. And what we fhall offer here, will be firft in relation to fingle words, then fentences, and laftly fc the paffions. I. Even in thofe fentences, which are expreffed in *33 c the moft even and fedate manner, there is often one It or more words which require an emphafis and diftinc- tion of the voice. Pronouns are often of this kind; as. This is the man. And fuch are many words, that denote the circumftances and qualities of things. tj Such as heighten or magnify the idea of the thing to which they are joined, elevate the voice; as noble, | admirable, majejlic, greatly, and the like. On the j' contrary, thofe which leffen the idea, or debafe it, deprefs the voice, or at leaft protraft the tone ; of ^1 which Jort are the words little, mean, poorly contemptible, with many others. Some tropes likewife, as meta¬ phors, and verbal figures, which confift in the repe¬ tition of a fingle word, fhould have a particular em¬ phafis. As when Virgil fays of the river Araxes, It difdained a bridge. And Nifus of himfelf in the fame poet, I, I am the man; where the repeated word is loudeft. This diftimftion of words, and giving them their proper emphafis, does not only render the ex- ;[• preffion more clear and intelligible; but very much ;j; contributes to the variation of the voice, and the pre- it venting a monotony. And the different pronuncia¬ tion of thefe words will alfo require a peculiar ge- t fture. II. In fentences, regard fhould be had to their 132 ■, length, and the number of their parts, in order to di- ftinguifh them by proper paufes. The frame and ftruc- i I ture of the period ought likewife to be confidered, that i| the voice may be fo managed, as to give it the moft mufical accent. Unlefs there be fome fpecial reafon for , j the contrary, it fhould end louder than it begins. And ; this difference of tone between the end of the former fentence, and the beginning of the next, not only helps || to diftinguifh the fenfe, but adds to the harmony of the voice. And that the laft fyliables of a fentence might become more audible and diftinft, was doubtlefs one i reafon why the ancient rhetoricians diflike ihort feet at | the end of a period. In an antithefis, or a fentence i confifting of oppofite parts, one contrary muft be louder than the other. As : “ He is gone, but by a gain¬ ful remove, from painful labour, to quiet reft ; from un- quiet defirescontentment,yruzK forrow, / imitation of the belt examples.

Syjlem of Oratory.'} O R C Oratory, among the Romanifts, a clofet or like apartment near a bed-chamber, furnilhed with an al- . tar, crucifix, &c. for private devotions. ORB, in aftronomy, denotes an hollow globe or fphere. Orb, in taftics, is the difpofing of a number of foldiers in circular form of defence. The orb has been thought of confequence enough to employ the attention - of the famous marfhal de Puyfegur in his art of war, who prefers this pofition to throw a body of infantry in an open country, to refift caval¬ ry, or even 3 fuperior force of infantry ; becaufe it is regular, and equally ftrong, and gives an enemy no reafon to expeft better fuccefs by attacking one place than another. Caefar drew his whole army in this form, when he fought againft Labienus. The whole army of the Gauls were formed into an orb, under the command of Sabinus and Cotta, when fighting againft the Romans. The orb was generally formed fix deep. ORBIT, in aftronomy, the path of a planet or co¬ met, or the curve that it defcribes in its revolutipn round its central body : thus, the earth’s orbit is the curve which it defcribes in its annual courfe round the fun, and ufually called ih.s ecliptic. See Astronomy, pajfim. ORCADES, the Orkney Iflands. See Orkney. ORCHARD, a garden-department, configned entirely to the growth of ftandard fruit-trees, for furnifiiing a large fupply of the moft ufeful kinds of fruit. In the orchard you may have, as ftandards, all forts of apple-trees, moft forts of pears and plums, and all forts of cherries: which four fpecies are the capital or¬ chard fruits ; each of them comprifing numerous valu¬ able varieties. But to have a complete orchard, you may alfo have quinces, medlars, mulberries, fervice-trees, filberts, Spanifh nuts, berberries; likewife walnuts and chefnuts; which two latter are particularly appli¬ cable for the boundaries of orchards, to fcreen the other trees from the infults of impetuous winds and cold blafts. All the trees ought to be arranged in rows from 20 to 30 feet diftance, as hereafter direfted. But fometimes orchards confift intirely of apple- trees, particularly in the cyder-making counties, where they are cultivated in very great quantities in large fields, and in hedge-rows, for the fruit to make cyder for public fupply. And fometimes whole orchards of very confiderable extent are entirely of cherry-trees. But in this cafe, it is when the fruit is defigned for fale in fome great O R C city, as London, &c. for the fupply of which city, Orch^ great numbers of large cherry-orchards are in fome of the adjacent counties, but more particularly in Kent, which is famous for very extenfive cherry- orchards; many of which are entirely of that fort call- ed Kentijh cherry, as being generally a great .bearer; others are ftored with all the principal forts of culti- ‘ vated cherries, from the earlieft to the lateft kinds. See Prunus Cerafus. A general orchard, however, compofed of all the before-mentioned fruit-trees, (hould confift of a double portion of apple-trees or more, becaufe they are con- fiderably the moft ufeful fruit, and may be continued for ufe the year round. The utility of a general orchard, both for private ■ ufe and profit, ftored with the various forts of fruit- fl trees, muft be very great, as well as afford infinite plea- || fure from the delightful appearance it makes from early ;| fpring till late in autumn: In fpring the various trees in bloffom are highly ornamental; in fummer, the (i| pleafure is heightened by obferving the various fruits .J advancing to perfeftion ; and as the feafon advances, the mature growth of the difl;erent fpecies arriving to :l perfeftion, in regular fucceffion, from May or June, 'll until the end of Oftobtr, muft afford exceeding de¬ light, as well as great profit. Of the proper Extent, Situation, and Soil, for this 11 Department.~\ As to the proper extent of ground for i I an orchard, this muft be proportioned, in fome mea- i | fure, to the extent of land you have to work on, and the quantity of fruit required either for private ufe or i I for public fupply: fo that an orchard may be from ' J half an acre to 20 or more in extent. With refpeft to the fituation and afpeft for an orch¬ ard, we may obferve very thriving orchards both in low and high fituations, and on declivities and plains, in various afpefts or expofures, provided the natural foil is good : we (hould, however, avoid very low damp fituations as much as the nature of the place will j| admit; for in very wet foils no fruit trees will profper, nor the fruit be fine : but a moderately low fituation, free from copious wet, may be more eligible than an elevated ground, as being lefs expofed to t'empeftuous winds; though a fituation having a fmall declivity is very defirable, efpecially if its afpeft incline towards ,> the eaft, fauth-eaft, or foutherly, which are rather ;!i' more eligible than a wefterly afpeft; but a north afpeft is the word of all for an orchard, unlefs particu- larly compenfated by the peculiar temperament or > good quality of the foil. And as for foil, any common field or pafture that pro- | Orchard. O R C [ 5743 ] O R C produces good crops of corn, grafs, or kitchen-gar- ' den vegetables, is luitable for an orchard, if it fhoiild prove of a loamy nature, it will be a particular advan¬ tage : any foil, however, of a good quality, not too light and dry, or too heavy, ftubborn, or wet, but of a medium nature, of a foft, pliant temperature, not lefs than one fpade deep of good ftaple, will beproperfor this purpofe. Preparation of the. Ground.^ The preparation of the ground for the reception of trees, is by trenching; or, if for very confiderable orchards, by deep ploughing; but trench-digging, one or two fpades, as the foil will admit, is the mod eligible, either wholly^ or only for the prefent ip the places where the lines of trees are to ftand, a fpaGe of fix or eight feet wide, all the way in each row, efpecially if it be grafsrground, and in¬ tended to be kept in the fwaird; or if any under-crops are defigned to be raifed, the ground may be whol¬ ly trenched at firft : in either cafe trench the ground in the ufual way to the depth of the- natpral foil; and if in grafs, turn the fward clean to the bottom of each trench, which, when rotted, will prove an excellent ma¬ nure. In planting orchards, however, on grafs-grounds, fome only dig pits for each tree, capacious enough for the reception of the roots, loofening the bottom well, without the labour of digging any other part of the ground. ' The ground muft be fenced fecurely againft cattle, &c. either with a good ditch and hedge, or with a paling-fence, as may be moft convenient. See Hedge. Method of planting the Trees. The belt feafon for planting all the forts of fruit-trees is autumn, foon af¬ ter the fall of the leaf, from about the latter end of October until December ; or indeed it might be per¬ formed any time in open weather from October until March. Choofe principally full ftandards, with ftraight clean Items, fix feet high; each with a branchy well-formed head, of from two or three to four or five years growth; and let feveral varieties of each particular fpecies becho- fen, that ripen their fruit at different times, from the earlieft to the lateft, according to the nature of the different forts, that there may be a proper fupply of every fort regularly during their proper feafon. Of apples and pears in particular, choofe a much greater quantity of the autumnal and late-ripening kinds than of the early forts; but moft of all of apples : for the fummer-ripening fruit is but of fhort duration, only proper for temporary fervice ; but the later-ripening kinds keep found fome confiderable time for autumnal ufe ; and the lateft forts that ripen in Oftober, con¬ tinue in perfe&ion for various ufes all winter, and fe¬ veral forts until the feafon of apples come again. Having- made choice of the proper forts, and mark¬ ed them, let them be taken up with the utmoft care, fo as to preferve all their, roots as entire as poflible; and when taken up, prune off any broken or bruifed parts of the roots, and juft tip the ends of the princi¬ pal roots, in general, with the knife, on the under fide, with a kind of flope outward. If the trees have been already headed, or fo train¬ ed as to have branched out into regular fhoots to form each a proper head, they muft be planted with the faid heads entire, only retrenching or fhortening any Vol. VIII. 2 irregular or ill-placed fhoot that takes an aukward di- reftion, or grows acrofs its neighbours, or fuch as may run confiderably longer than all the reft, &c. The arrangement of the trees in the orchard muft be in rows, each kind feparate, at diftances according to the nature of growth of the different forts; but for the larger growing kinds, fuch as apples, pears, plums, cherries, &e. they Ihould ftand from 25 to 30 or 40 feet every way afunder, though 25 or 30 feet at moft is a reafonable diftance for all thefe kinds. Each fpecies and its varieties fhould generally be in rows by themfelves, the better to fuit their refpedlive modes-of growth: tho’ for variety, there may be fome rows of apples and pears arranged alternately, asalfo of plums and cherries ; and towards the boundaries there may be ranges of leffer growth, as quinces, medlars, filberts, &c. and the outer row of all may be walnut- trees, and fome chefnuts, fet pretty clofe to defend the other trees from violent winds. According to the above diftances, proceed to {lake out the ground for making the holes for the reception of the trees; which if made to range every way, will have a very agreeable effeft, and admit the currency of air, and the fun’s influence more effeftually. But in planting very extenfive orchards, fome di¬ vide the ground into large fquares or quarters, of dif- ferent dimenfions, with intervals of fifty feet wide be¬ tween'; ferving both as walks, and for admitting a greater currency of air; in different quarters planting different forts of fruit, as apples in one, pears in an¬ other, and plums and cherries in others, &c. and thus it may be repeated to as many quarters for each fpe¬ cies and its varieties as may be convenient. As to the mode of planting the trees : A wide hole muft be dug for each tree, capacious enough to re¬ ceive all the roots freely every way without touching the fides. When the holes are all ready, proceed to planting, one tree in each hole, a perfon holding the ftem ere&, whilft another trims in the earth, pre- vioufly breaking it fmall, and cafting it in equally all about the roots, frequently (baking the tree to caufe the mould to fettle in clofe about all the fmaller roots and fibres, and fo as to raife the tree gradually up, that the crown of the roots may be but two or three inches below the general furface ; and when the hole is filled up, tread it gently, firft round the outfide, then near the ftem of the tree, forming the furface a little hollow; and then if on the top of all is laid fome inverted turf to the width of the holes, forming it with a fort of circular-bank, three or four inches high, it will fupport the tree, and guard the roots from dry¬ ing winds and the fummer’s drought: obferving that each tree ftand perfedly upright, and that they range exaftly in their proper rows. ORCHESTRA, in the ancient theatres, a place in the form of a femicircle, where the dancing was perform¬ ed. In the Greek theatres, the orcheftra made part of the ftage; but, among the Romans, it anfwered nearly to our pit; only that in it were difpofed the feats for the fenators, magiftrates, veftals, and other perfons of diftin&ion. ORCHIS, fool-stones ; a genus of the diandria order, belonging to the gynandria clafs of plants. There are a great many fpecies; but the mod remark¬ able are the following. 32 L Orchard !i Qrchif. I. The O R C [ 5744 1 O R D Orchis, i. The mafcula, or male fool-Hones, hath 3 root Ordeal, compofed of two bulbs, crowned with oblong, broad, "'’"Tpotted leaves; upright-flalks, a foot high; garnifhed with one or two narrow amplexicaule leaves; and ter¬ minated by a long fpike of reddifh-purple flowers, ha¬ ving the petals reflexed backward; a quadrilobed cre- nated lip to the •ne&arium, and an obtufe horn. The flowers of this fpecies pofiefs a very agreeable odour. 2. The morio, or female orchis, hath a double bul¬ bous root, crowned with oblong, ribbed, fpreading leaves; ereft flower-ftalks, eight or ten inches high; garnifhed with a few amplexicaule leaves; and termi¬ nated by a Ihort loofe fpike of flowers, having conni- vent petals, a quadrifid crenated lip to the nedarium, and an obtufe horn. 3. The militaris, or man-orchis, hath a double bul¬ bous root, crowned with oblong amplexicaule leaves; ereft flower-italks, eight or ten inches high ; termi¬ nated by a loofe fpike of afh-coloured and reddifli flowers, having confluent petals; a quinquefid, rough, fpotted lip to the nedarium, and an obtufe horn. The flrudure of the flowers exhibit the figure of a naked man; and are often of different colours in the fame flower, as afh-colour, red, brown, and dark-ftriped. Culture and Properties. All the orchifes are very hardy perennials, with bulbous flefhy roots. The flowers appear in May, June, and July, but princi¬ pally in June: their mode of flowering is univerfally in fpikes, many flowers in each fpike; and each flower is compofed of five petals in two feries, and a neda- rium. The feafon for removing them is in fummer, after they have done flowering, when their leaves and ftalks decay: plant them three inches deep, and let them remain undifturbed feveral years; for the lefs they are removed, the ftrooger they will flower. The roots of all the fpecies have a remarkable re- femblance to the fcrotum of animals, whence the name. This plant flouriflies in various parts of Eu¬ rope and Afia, and grows in our country fponta- neoufly, and in great abundance. It is afliduoufly cul¬ tivated in the Eaft; and the root of it forms a confi- derable part of the diet of the inhabitants of Turkey, Perfia, and Syria. From it is made the alimentary powder called salep ; which, prepared from foreign roots, is fold at five or fix (hillings per pound, though it might be furniflied by ourfelves at the fixth part of that price, if we chofe to pay any attention to the culture of this plant. The orchis mafcula is the moft valued for this purpofe. A dry and not very fertile foil is beft adapted to its growth. The propereft time for gathering the roots, is when the feed is formed, aud the (lalk is ready to fall; be- caufe the new bulb, of which the falep is made, is then arrived to its full maturity, and may be diftin- guiflied from the old one, by a white bud rifing from the top of it, which is the germ of the orchis of the fucceeding year. The culture of the orchis is an objeft highly de- ferving of encouragement from all the lovers of agri¬ culture. And as the root, if introduced into com¬ mon ufe, would furnifh a cheap, wholefome, and moft nutritious article of diet, the growth of it would be fufficiently profitable to the farmer. See Salep. ORDEAL, an ancient form of trial. See Trial. It was peculiarly diftinguiftied by the appellation of judicium Dei; and fometimes vulgaris purgatio, to Ordeal, diftinguifli it from the canonical purgation, which was” by the oath of the party. This was of two forts, either fire-ordeal, or water-ordeal; the former being confined to perfons of higher rank, the latter to the common people. Both thefe might be performed by deputy : but the principal was to anfwer for the fuc- cefs of the trial; the deputy only venturing foroe cor¬ poral pain, for hire, or perhaps for friendfliip. Fire-ordeal was performed either by taking up in the hand, unhurt, a piece of red-hot iron, of one, two, or three pounds weight ; or elfe by walking, barefoot, and blindfold, over nine red-hot ploughfhares, laid length- wife at unequal diftances: and if the party efcaped being hurt, he was adjudged innocent; but if it hap¬ pened otherwife, as without collufion it ufually did, he was then condemned as guilty. However, by this latter method queen Emma, the mother of Edward the Confeffor, is mentioned to have cleared her charac¬ ter, when fufpe&ed of Familiarity with Alwyn bifliop of Winchefter. Water-ordeal was performed, either by plunging the bare arm up to the elbow in boiling-water, and efcaping unhurt thereby: or by calling the perfon fufpe6led into a river or pond of cold water; and, if he floated therein without any a&ion of fwimming, it was deemed an evidence of his guilt; but, if he funk, he was acquitted. It is eafy to trace out the traditional relics of this water-ordeal, in the ignorant barbarity Hill pradifed in many countries to difcover witches, by calling them into a pool of water, and drowning them to prove their innocence. And in the Eaftern empire the fire-ordeal was ufed to the fame purpofe by the emperor Theodore Lafcaris ; who, at¬ tributing his ficknefs to magic, caufed all thofe whom he fufpefted to handle the hot iron: thus joining (as has been well remarked) to the moft dubious ccime in the world, the moft dubious proof of innocence. And indeed this purgation by ordeal feems to have been very ancient, and very univerfal in the times of fuperflnious barbarity. It was known to the ancient Greeks : for in the Antigone of Sophocles, a perfon, fufpedked by Creon of a mifdemefnor, declares himfelf ready “ to handle hot iron, and to walk over fire,” in order to manifeft his innocence; which, the fcholiaft tells us, was then a very ufual purgation. And Grotius gives us many inftances of water-ordeal in Bithynia, Sardinia, and other places. There is alfo a very peculiar fpecies of water-ordeal, faid to prevail among the Indians on the coaft of Malabar ; where a perfon accufed of any enormous crime is obliged to fwira over a large river abounding with crocodiles, and, if he efcapes unhurt, he is reputed innocent. j As in Siam, befides the ufual methods of fire and water ordeal, both parties are fometimes expofed to the fury of a tiger let loofe for that purpofe : and, if the bead fpares either, that perfon is accounted in¬ nocent ; if neither, both are held to be guilty ; but if he fpares both, the trial is incomplete, and they proceed to a more certain criterions. One cannot but be aftonilhed at the folly and im¬ piety of pronouncing a man guilty, unlefs he was cleared by a miracle ; and of expecting that all the powers of nature (hould be fufpended, by an imme¬ diate interpofition of Providence to fave the innocent, whenever O R D [ 5745 ] O R D > Order whenever It was prefumptuoufly required. And yet ,9 in England, fo late as king John’s time, we find | Quinary. grants t0 t^e bifhops and clergy to ufe the judicium Jerri, aquie, et ignis. And, both in England and Sweden, the clergy prefided at this trial, and it was only performed in the churches or in other confecrated ground : for which Stiernhook gives the r.eafon, Non defuit Mis opera et laboris pretium; femper enim ab ejufmodi judicio a liquid lucri facerdotibus obveniebat. But, to give it its due praife, we find the canon law very early declaring againll trial by ordeal, ox vulgaris purgatio, as being the fabric of the devil, cum Jit con¬ tra praceptum Domini, Non tentabis Dominum Deum tuum. Upon this authority, though the canons them- felves were of no validity in England, it was thought proper {as had been done in Denmark above a century before) to difufe and abolifh this trial entirely in our courts of juttice, by an aft of parliament in 3 Hen.

Ordination has always been efteemed the principal prerogative of bifhops, and they ftill retain the func¬ tion as a mark of fpiritual fovcreignty in their dio- cefe. Without ordination, no perfon can receive any benefice, parfonage, vicarage, &c. A clerk mult be 23 years of age before he can have any lhare in the miniftry; and 24 before he can be ordained, and by that means be permitted to adminifter the fa- crament. A bifhop, on the ordination of clergymen, is to examine them in the prefence of the minifters who affift him at the impofition of hands; and in cafe any crime, as drunkenncfs, perjury, forgery, &c. be alleged againft any one that is to be ordained, either prieft or deacon, the bilhop ought to defift from ordain¬ ing him. The perfon to be ordained is to bring a teftimonial of his life and doftrine to the bilhop, and give account of his faith in Latin, and both priefts and deacons are obliged to fubfcribe the 39 articles. The ordination-days in the church of England, are the four Sundays immediately following the Ember- weeks, r/z. the firft Sunday in Lent, Trinity-Sunday, and the Sundays following the firft Wednefday after September 14. and December 13. In Scotland, where there are no bilhops, the power of ordination is lodged in the prefbytery. See Pres¬ bytery. ORDNANCE, a general name for all forts of great guns ufed in war. See Gunnery. Boring of Ordnance. Till within thefe to years, iron ordnance were call with a cylindrical cavity, near¬ ly of the dimenfions of the caliber of the piece, which was afterwards enlarged to the proper caliber by means of fteel-cutters fixed into the dog-head of a boring- bar iron. Three fide-cutters equidiftant were requifite to preferve the caliber ftraight and cylindrical; and a fingle cutter was ufed at the end of'the bar to fmooth the breech of the piece. In boring ordnance call hol¬ low, the piece was fixed upon a carriage that could be moved backwards and forwards in a direft line with the centre of a water-wheel; in this centre was fixed the boring bar, of a fufficient length to reach up to the breech of the piece, or more properly to the fur¬ ther end of the caliber. The carriage with the piece being drawn backwards from the centre of the water¬ wheel to introduce the boring and finifhingbars and cut¬ ters, it is then preffed forwards upon this bar by means of levers, weights, &c. and the water-wheel being fet agoing, the bar and fullers are turned round, and clean out and fmooth the caliber to its proper dimenfions. Experience at laft pointed out many inconveniences arifing from the method of calling guns hollonss, and widening the calibers by thefe boring bars. For the body of iron of the hollow gun, being, at calling, in contaft with the core that made the caliber within-fide, and with the mould without-fide, began to confolidate towards thefe fides in the firft place, foonerthan in the intermediate fpace, where of courfe the contraftion of 32 L a the ORE [ 5746 ] O R G Ordnance, the Iron takes place; by which means, all guns cad Ordon- {)0]jow became more or lefs fpongy where they 1_ ought to have been mod compaft ; and numberlefs ca¬ vities alfo were created round the cores, from itagna- ted air generated in them, which were too deep to be cut out by the boring. To remedy thefe defers, iron ordnance is now uni- verfally cad folid, by which means the column of iron is greatly enlarged, and the grain more comprefled; and the contraction of the iron becomes in the heart of the column, and confequently is cut out by the per¬ foration for the caliber. ^ pj -g Guns arebored out of the folid reverfely from the hol- G'XXXH. low method. The piece A is placed upon two dan- dards BB, by means of two journeys; turned round by the water-wheel C, the breech I) being introduced into the centre of the wheel, wit It the muzzle towards the hiding carriage E, which is prefi'ed forwards by a rach F, and weights in the fame way as the gun-car¬ riage was in hollow boring. Upon this Aiding car¬ riage is fixed, truly horizontal, and centrical to the gun, the drill-bar G, to the end of which is fixed a carp’s- tongue drill or cutter H ; which, being prefled forward upon the piece whild it is turning round, perforates the bore, which is afterwards finilhed with bars and cut¬ ters as the hollow guns were. The principal difaculty of perforated folid guns truly centrical, arifes from the contraSidn of the iron above-mentioned; which, refill¬ ing the drill unequally, tends to throw it out of the centrical line.

ORESTES, in ancient hiflory, king of Mycenae, was the fon of Agamemnon and Clytemneftra. At the infligation. of his fifter Eledra, he revenged the death of his father, and did not even fpare his own mother. He alfo killed Pyrrhus the fon of Achilles, for taking away Hermione, who had-been promifed to him in marriage. It is faid, that, after he had killed his mother, he went diftra&ed; and that, to expiate his crime, he was obliged to go to the temple of Diana in the Cherfonefus T^urica. His friend Py- lades accompanied him thither: when king Thoas re- folving to facrifice him to Diana, to whom human viftims were offered, Pylades refolving to be facrificed to fave his friend, aflTured that prince that he was Greftes; while Oreftes, on the contrary, to prevent the death of Pylades, maintained that he alone was the true Orefies. During this generous contefl, which rendered the friendfhip of Orefies and Pylades the ad¬ miration of the world, Iphigenia, who prtfided at Diana’s fpcrifices, knew again her brother Orelles, and delivered him from the danger to which he was expofed.

ORGAN, in general, is an inftrument or machine defigned for the produdtion of fome certain adtion or operation; in which fenfe the mechanic powers, ma¬ chines, and even the veins, arteries, nerves, mufcles, and bones of the human body, may be called organs. Organ, in mufic, the largeft and mod harmonious wind-inflrument. The invention of the organ is very ancient; though it is agreed that It was little ufed till the eighth cen¬ tury. It feems to have been borrowed from the Greeks. Vitruvius defcribes an hydraulic one in his tenth book of Architeflure. The emperor Julian has an epigram in its praife. St Jerom mentions one with twelve pair of bellows, which might be heard a thou- fand paces, or a mile; and another at Jerufalem, which might be heard at the mount of Olives. The church-organ confifts of two parts; the main body, called \he great organ; ^nd the pofitive or little organ, which forms a fmall cafe or buffet, commonly placed before the great organ. The iize of an organ is generally expreffed by the length of its largeft pipe: thus they fay, an organ of 8, j6, 32 feet, £gV. The organ in the cathedral church at Ulm in Germany is 93 feet high, and 28 broad: its largeft pipe is 13 inches diameter, and it has 16 pair of bellows. The feveral parts of the church-organ are as follow- HIH is the found-board : which is compofed of two parts, the upper board or cover HHH, and the under board HI, which is much thicker than the other; each of thefe confifta of feveral planks laid with their edges to each other, and joined very clofe together. In the under-fide of the lower board there are made feveral channels, which run in the dire’&ion LL, MM, &c. and are continued as far as there are flops in the organ, and come almoft to the edge HK. Thefe channels are covered over very clofe with parchment or leather all the way, except a hole that is commonly at the fore-end next HK, upon which a valve or puff is placed. Thefe channels are called partitions. When this valve or flap is flint it keeps out the air,' and ad¬ mits it when open. On the upper fide 'of the lower board there are likevvife cut feveral broad fquare chan¬ nels, lying crofs the former, but not fo deep as to reach them; thefc lie in the dire&ion LN, &c. To fit thefe channels, there are the fame number of wooden Aiders or regifters./J &c. running the whole length; and thefe may be drawn outer thrufl in at pleafure. The number of thefe is the fame as that of the flops in the organ. IKKK is the wind cheft, which is a fquare box fitted clofe to the under fide of the lower board, and made air-tight, fo that no air can get out but what goes through the valves along the partitions. VV are the valves or puffs which open into the wind-chdl ; they are all inclofed in it, and may be placed in any part of it, as occafion fhall require. One of thefe valves, with the fpring that flints it, and the wire that opens it, is reprefented by fig. 2. C, D, E, F, &c. are the keys on which the fingers are placed when the organ is played : thefe keys lie over the horizontal bar of wood W, in which are ftuck an equal number of wire-pins 2, 2, on which keys are Organ. fixed; and the keys move up and down on the bar, as on a centre. There is another bar, againft which the keys fall when put down, and which is heremark- 3 : on this alfo are feveral w-ires, which go through the keys, to guide them ; and on this bar a lift is fa- llened to hinder the keys from knocking againft the wood. The keys are made to communicate with the valves feveral ways, as we fhall now deferibe. Firft, /, /, /, are the key-rollers, moving on the pivots t, t: thefe rollers lie horizontally, one above another, and are of fuch a length as to reach from the valve to the key ; a, a, a, are arms or levers fixed to the key-rollers : w, to, the valve-wires fixed to the arms a, a, and to valves V, and go through the holes h, h, in the bottom of the wind-cheft : b, b, b, are likewife arms fixed to the kty-rollers: d, d, d, the key-wires, fixed to the arms b, b, and to the keys C, D, E. Now, when the end of any one of the keys C, D, E, is put down, it pulls down the arm b, by the wure d, which turns about the roller s with the arm a, that pulls down the wire to, which opens the valve that is {hut by the fpring as foon as the preffure is taken off the key. In this conftruftion there muftbea worm-fpring faftened to the key, and to the bar W on the further fide, to keep down the end 5 of the key. Another method of opening the valves is thus: xy, xyt are flender levers, moveable on the centres J, 1 ; 5 x, 5 x, are wires going from the further ends of the keys to the ends x of the levers ; y V, y V, are other wires, reaching from the ends/of the levers, through the holes b, to the valves V. So that putting down the key C, D, &c. raifes the end 5, which thruftsup the end i of the lever, by the wive 5 x; this depreffes the end/ of the lever, which pulls down the wire/V, and opens the valve V. A third way of opening the valves is this : At the end of the key b, is a lever 8, 9, moving in the cen¬ tre 7. This makes, with the key, a compound lever. From the end 9, a wire goes to the valve. Now the putting down ti?e end 6 of the key, raifes the end 8, which depreffes the end 9, of the lever 8, 9,, pulls down the wire, and opens the valve. There is only one of thefe drawn in the fcheme, and but a few of the others, to avoid confufion. R, R, are the rollers, to move the Aiders, by help of the arms cf cfj which are fixed horizontally in thefe rollers: be, k ey are alfo levers fixed in the rollers; le, le, are the handles, whieh lie horizontal¬ ly, and pafs through the holes/, /; they are faftened to the lever k e, being moveable about a joint at e. Now, any handle Ip, being drawn out, puljs the end e toward /, which .turns about R4, along w’ith, the arm cf; and the end f pulls -out the Aider fg; and when p is thruft in, the arm likewife thrufts in the Aider Upon the feveral. rows of holes which appear on the top of the upper board, there are fet up; an equal numberof rows of pipes. The pipes of an organ are of two kinds ; the one has a mouth like a flute, the other with reeds. The firft, called pipes of mutationy confift, (1.) of a foot AABB (fig. 3.) which is a< hbllow cone, that receives the wind that is to found the pipe: (a.) To this foot is fattened the body of O R G [ 574B ] O R G Organ, the pipe BBDD. Between the foot and the body of " the pipe is a diaphragm or partition FEF, that has a long but narrow aperture by which the wind comes out; over this aperture is the mouth BBC, whofe upper lip C, being level, cuts the wind as it comes out. The pipes are of pewter, of lead mixed with a a twelfth part of tin, and of wood. Thofe of pew¬ ter are always open at their extremities : their diame¬ ter is very fmall, and their found very clear and {hrill. Thofe of lead mixed with tin are larger; the flrorteft are open, the longeft quite flopped ; thofe of a mean fize are partly flopped, and have befide a little ear on each fide the mouth, to be drawn clofer or fet further afunder, in order to raife or lower the found. The wooden pipes are fquare, and their extremity is flop¬ ped with a valve or tampion of leather. The found of the wooden and leaden pipes is very foft ; the large ones flopped are commonly of wood, the fmall ones of lead. The longeft pipes give the graved found, and the ftiorteft the moft acute: their lengths and widths are determined by a fixed proportion to their founds ; and their divifions are regulated by a rule, which is called the diapafon. The longeft has com¬ monly 16 feet ; but in very large organs it has 32 feet. The pedal tubes are always upon, though made of wood and of lead. Whatever note any open pipe founds, when its mouth is flopped it will found an o&ave lower; and a pipe of twice its capacity will likewife found an oftave lower. A reed-pipe contifts of a foot A ABB, (fig. 4.) that carries the wind into the (ballot or reed CD, which is a hollow demi-cylinder, fitted at its extremity D, into a fort of mould, by a wooden tampion G. The fhallot is covered with a plate of copper KKLL, fit¬ ted at its extremity II, into the mould, by the fame wooden tampion. Its other extremity KK, is at liber¬ ty : fo that the air entering the fhallot makes it tremble or (hake againft the reed ; and the' longer that part of the tongue IL, which is at liberty, is made, the deeper is the found. The mould II, that ferves to fix the (hallot or reed, the tongue, tampion, &c. ferves alfo to flop the foot of the pipe, and make the wind go out wholly at the reed. Laftly, in the mould is foldered the tube HH, whofe inward open¬ ing is a continuation of that of the reed : the form of this tube is different in different ranks of pipes. The degree of acutenefs or gravity in the found of a reed pipe, depends on the length of the tongue, and that of the pipe CK, taken from the extremity of the (hallot to the extremity of the tube. The quantity or inten¬ tion of the found depends on the width of the reed, the tongue, and the tube ; as alfo on the thicknefs of the tongue, the figure of the tube, and the quantity of wind. To diverlify the founds of the pipes, a valve is added to the port-vent, which makes the wind go out in fits or (hakes. In fig. 1. X reprefents a flute- pipe of wood, Z a flute-pipe of metal, Y a trumpet- pipe of metal. The pipes, to prevent them from fall¬ ing, pafs through holes made in boards, placed upon the upper board. The pipes are made to communicate with the wind- cheft in the following manner. There are holes bored that go through the upper and lower boards, and through the flitter, (when it is drawn out), into the partition below ; fo that any pipes placed upon thofe Organ, boles will then communicate with the partition, which,- by its valve, communicates with the wind-cheft. But whep the Aider is thruft in, its holes do not anfwerto thofe in the upper and lower boards; therefore the communication is flopped, fo that no wind can get to the pipe. To every large organ there mud be at lead two pair of bellows, which are marked in fig. r. by TU, TU. O, O, are the handles, moving upon the axis nntnn. Each of thefe bellows confifts of two boards, the lowed of which is immoveable ; and in this there is a valve r, opening inwards, and a tube leading to if, called the conveying, tube. There is alfo a hole in this under board, from which a tube leads to the port- vent, which is a fquare tube marked 4, rifing upward, and inferted into the under fide of the wind-cheft at 2. In the tube leading to the port-vent there is a valve that opens towards the port-vent, and fuffersthe air to go up tke port-vent, but not to return. Now the handle O being pulled down, raifes the upper board T, and the air enters through the valve r; and when the handle is let go, the weight of the upper board, which carries three or four pound to every fquare foot, continually defcending, drives the air through the port-vent to the found-board : and as the bellows work alternately, one pair is conftantly de¬ fcending, which occafions a continual blaft through the port-vent. In chamber-organs there is but one pair of bellows ; but they are formed of three boards, in the manner of a fmith’s bellows, and fo have a con¬ tinual blaft. All the internal ftrufture of the organ is concealed from the fight by the front of the inftru- ment, which (lands upon the part between the num¬ bers 3 and 6 (fig. 1.) In every organ the number of partitions LL, MM, Sec. there are in the found-board (fig. 1.) that of the valves V V, that of the rollers / r, or of the levers x or 8 9 and their wires, and that of the keys ABC, Sec. muft be always equal. Large organs have commonly four or five fets of keys, befide thofe that belong to the pedals or large pipes, the flops to which are played by the feet. The keys of an organ are ufually divided into four oflaves ; which are, the fecond fub-o&ave, firft fub-oftave, middle o£ave, and firft oftave. Each oftave is divided into 12 flops or frets, of which feven are black and five white ; the for¬ mer mark the natural notes, and the latter the artifi¬ cial notes, that is, flats and (harps. The number of keys, therefore, when there are four o&aves, muft be 48. Some organifts add one or more flops to the firft and fecond fub-odlaves. The pedals have two or three oftaves, at the option of the organift ; fo that the number of flops is indeterminate. The keys are placed between GG (fig. 1.), but the fcheme could not contain them all. There are alfo as many handles /, /, &c. rollers RR, See. Aiders f, f. See. as there are flops upon the organ ; and it muft be obferved, that between the Aiders f, f, &c. there are as many Aiders on the right hand, and the fame number of handles and rollers, and other rows of pipes placed between LN, PQ^ which could not be expreffed in the figure. The lead pipes and partitions are placed toward the middle of the organ, and the greateft on the outfide. The OKI [ 5749 ] O R I Organ The flops of an organ have various denominations, ac- Onganum. corc3JDg t0 t{je founds they are to produce; Tome of which arediapafon, principal, fifteenth, twelfth, tearce, cornet, trumpet, French horn, vox humana, flute, baflbon, cremona, &c. There is likewife a contrivance to fwell the notes of fome of the flops- When this magnificent inftrument is played, the handle O of the bellows isfirft put down, which raifes the upper board T, and gives room for the air to en¬ ter by the valve r. Then the other handle O is put down ; in the mean time the board T, belonging to the firft handle, defcending, and /hutting the valve r, drives the air through the other valve, up the port- vent, and into the wind-eheft. Then drawing out any handle, as that of the flute-flop p /, which draws out the Aider/£, all the pipes in the fet LN are ready to play, as foon as the keys C,D,E, &e. are put down : therefore, if the key D be put down, it opens the cor- refponding valve wV, through which the air enters into the pipe X, and makes it found. In the fame manner any other pipe in the fet LN, will found when its key is put down ; but no pipe, in any other fet, will found till the Aider be drawn out by its correfpond- ing handle. Hydraulic Organ, denotes a mufical machine that plays by water inftead of wind. Of thefe there are feveral in Italy, in the grottos of vineyards. Cte- febes of Alexandria, who lived in the time of Ptole¬ my Euergetes, is faid to have invented organs that played by comprefling the air with water, as is (till pradlifed. Archimedes and Vitruvius have left us de- fcriptions of the hydraulic organ. ORGASM, an ecftafy, or impetuous defire of coition, occafioned by a turgefcency of the feminal vefiels. ORGIA, in antiquity, feafls and facrifices per¬ formed in honour of Bacchus, inftituted by Orpheus, and chiefly celebrated on the mountains by wild di- ftra&ed women called Baccha. See Bacchanalia, and Dionysia. ORGUES, in the military art, are thick long * pieces of wood, pointed at one end, and fliod with iron, clear one of another ; hanging each by a parti¬ cular rope or cord, over the gateway of a ftrong place, perpendicularly, to be let fall in cafe of the ap¬ proach of an enemy. Orgues, is alfo ufed for a machine compofed of feveral harquebufs or mulket barrels bound together, by means whereof feveral explofions are made at the fame time. It is ufed to defend breaches and other places attacked. ORGYA, an ancient Grecian meafure containing fix feet. ORIFICE, the mouth or aperture of a tube, pipe, or other cavity. ORIGANUM, Origany, or Marjoram; a ge¬ nus of the gymnofpermia order, belonging to the di- dynamia clafs of plants. The principal fpecies are, two hardy perennials and an annual for the open ground, and five perennials for the green-houfe : viz. i. The vulgare, or wild pot-marjoram; 2. The he- racleoticum, or winter fweet-marjoram. Thefe are finely-fcentcd aromatics, excellent for culinary pur- pofes, particularly for broths, foups, &c. they have likewife merit for medical ufes, and for giving fra- rance to ointments; fo that the plants are proper Orienf oth for kitchen and phyfic gardens, and may alfo °ri6f be employed in the pleafure-ground as plants of va¬ riety. 3. The marjorana, or annual fweet marjoram, is an aromatic of the higheft fragrance, is admirable for kitchen ufe, and excellent for nofegays ; fo is pro¬ per both for the kitchen and pleafure garden, but more particularly the former. It is often called knot- ted marjoram, from the flowers growing in clofe knot- ted-Iike heads. The following moftly affume an un- derfiirubby growth ; frequently with abiding ftalks, if they have ftielter here in winter. 4. The didtam- nus, or dittany of Crete ; 5. The fipyleum, or ori¬ ganum of mount Sipylus ; 6. The creticum, or Cre¬ tan origany ; 7. The fmyrmeum, or Smyrna origany; 8. The JEgyptiacum, or Egyptian origany. All thefe eight fpecies of origanum flower in July and Auguft; the flowers are fmall, monopetalous, rin- gent, univerfally hermaphrodite, and colledled into verticilli round the ftalks; fucceeded by ripe feed in autumn ; though in this country the annual marjoram and the three green-houfe forts feldom perfedt feed well, unlefs the autumn proves remarkably fine and warm : in default, however, of feed, the propagation of all the perennial forts, both hardy and green-houfe kinds, is eafily effedled by flips of the roots, &c. And the feed of the annual fort is imported plentifully from France or Italy, by the feed-dealers. ORIENT, a harbour of France, in the province of Bretagne, in the bottom of the bay of St Lewis. Since the year 1720, a handfome town has been built here, where the Eaft India company have large ma¬ gazines. The Englifli attempted to become mafters of it in 1746, but mifcarried. W. Long. 3. 22. N. Lat. 47. 45. ORIGEN, one of the moft celebrated ecclefiaftical writers, greateft geniufes, and mod; learned men of the primitive church, during the third century, was born at Alexandria, in the year 185; and was fur- named Adamantus, either from his indefatigable ap¬ plication to ftudy, or the firmnefs he difcovered amidfl: the torments he fuffered for the faith. Leonides his father educated him with care,-and made him apply to the ftudy of the Holy Scriptures from his infancy, in which he made furprifing progrefs. He had after¬ wards St. Clement of Alexandria for his mafter in divinity, and at 18 years of age fucceeded that great man in the office of catechift, an important employ¬ ment, which confifted in teaching divinity, and ex¬ pounding the Scriptures. Leonides his father had fuffered martyrdom the year before, during the per- fecution of Severus in 202 ; and Origen had ftiewn fuch eagernefs to follow his father to martyrdom, that his mother was obliged to hide his cloaths, to prevent his going abroad. Origen had a great concourfe of au¬ ditors who attended his fchool, fome of whom were of the faithful, and the others pagans. He confirmed and ftrengthened the firft in their faith, and converted moft of the others; and there were fuch a number of martyrs amongft his difciples, that it might be faid, that he kept rather a fchool of martyrdom than of divinity. He taught the dofhines of Chriftianity to the girls and women as well as to the men; and, taking in a too literal fenfe what Chrift fays of becoming vo¬ luntary eunuchs, caftrated himfelf, to prevent his de- O R I Origen. ferving or fufferlng fcandal. He took a voyage to — Rome in 211; and at his return publilhed many works, by which he acquired an extraordinary reputation, that drew to him a great number of auditors. But Demetrius,bifltop of Alexandria, conceiving ajealoufy of him, endeavoured by various pretences to injure him. At length Origen went to Antioch, whither the emprefs Mammasa had fent for him to hear him difcourfe on the Chrrftian religion; he did not how¬ ever ftay long there, but returned to Alexandria, where he continued to teach till the year 288, when he left that city,, and travelled into Achaia. In that journey he went into Paleftine, and was ordained by the bilbops of that province at 4.2 years of age. His being ordianed by foreign bilhops without the per- miffion of Demetrius, renewned that prelate’s refent- ment againft. him ; on which Origen haftily returned to Alexandria, to endeavour to mollify him ; but De¬ metrius drove him from thence in 231, and caufed him to be excommunicated, and even depofed in a council held in Egypt. Origen then retired to Csfa- ria in Paleftine, where he railed a celebrated fchool, and had St Gregory Thaumaturgus, and a great number of other perfons who were illuftrious for their virtue and learning, for his difciples. He afterwards travelled to Athens; and then, at the defire of Firmi- lianus, ftaid fome time at Ctefaria in Cappadocia; whence he was invited into Arabia, to convince and bring back to the truth Beryllus, bilhop of Boftra, who maintained that the Word had no exiftence before his incarnation. Origen had the happinefs to make him fenlible of his miftake ; and fome years after was fent for into Arabia by an aftembly of biftiops, to difpute again the Arabians, who maintained that the fouls of the dead remained in a ftate of infenfibility till the general refurre&ion. At length the feventh perfecu- tion of the Chriftians began in the reign of Decius, and none were uied with greater feverity than Origen. He fopported with incredible conftancy the dreadful torments which-the perfecutors of the Chriftians in¬ vented againft them ; torments that were the more in- fupportable, as they were made to continue a long time, and as they took the greateft care to prevent his expiring in the midft of his tortures; but in the midft of the moft excruciating torments, he difeovered an heroic courage, and fuffered nothing to efcape him that was unworthy a difciple of Jefus Chrift. He died at Tyre in 254, aged 69. He was the author of a great number of excellent works. The principal of thofe which have been handed down to us are, 1. A Treatife againft Celfus, of which Spencer has given a good edition in Greek and Latin, with notes : this learned treatife has been tranflated into French by Elias Bouhereau, a proteftant minifter, born at Rochelle. 2. A great number of Homilies, with Commentaries on the Holy Scriptures. 3. Philocalia, and feveral other treatifes. 4. Fragments of his Hexaples, col- k&ed by father Montfaucon, in two volumes folio. Of all Origen’s books, the lofs of the Hexaples is moft to be regretted. This work was thus named from its containing fix columns; in the firft of which was the Hebrew text of the Bible; in the fecond, the fame text in Greek chara&ers; in the third, the Greek verfion of the Septuagint; in the fourth, that of Aquila ; in the fifth, that of Symmachus; and in the O R I fixth, Theodotian’s Greek verfion. This admirable Origenifts; in work gave the firft. hint for our Polyglot Bibles. II 5. The book of Principles; of which we have only an 0ri° incorreft Latin verfion. In all his writings he dif- covers a furprifing degree of modefty, candour, and humility ; a noble and fublime genius, profound learning, and vaft erudition. His manners were ’ex¬ tremely pure, and he had a warm zeal for fpreading the truths and morals of the gofpel. The moft complete edition of his works is that of father de la Rue, a Be- nedi&ine, in Greek and Latin. He ought not to be confounded with another Ori¬ gen, a Platonic philofopher, and the. difciple and friend of Porphyry, who ftudied philofpphy under Ammonius. ORIGENISTS, in church-hiftory, a Chriftian fed in the fourth century, fo called from their drawing their opinions from the writings of Origen. The Origenifts maintained, that the fouls of men had a pre-exiftent ftate ; that they were holy intelligences, and had finned in heaven before the body was created ; that Chrift is only the fon of God by adoption; that he has been fucceffively united with all the angelical natures, and has been a cherub, a feraph, and all the edeftial virtues one after another ; that, in future ages, he will be crucified for the falvation of the devils, as he has already been for that of men ; and that their punilhment, and that of the damned, will continue only for a certain limited time. ORIGINAL, a firft draught or defign of any thing, which ferves as a model to be imitated or copied. Original Sin, the crime of eating the forbidden fruit, of which, it is faid, all mankind are guilty at their conception, by the imputation of Adam’s tranf- grefiion ; which is accounted for by fuppofing, that Adam, as he was to be the father, was alfo the foa- deral head and reprefentative, of the whole human human race : and that, on his finning, all that were to fpring from him partook of his crimes. ORIGUELA, a town of Spain in Valentia. It is feated between the mountains on the banks of the river Segura, in a place fortified by nature, and in a fertile plain, abounding in all things, efpecially corn. It is furrounded with pleafant gardens, and has a univerfity and a bifhop’s fee. It is defended by an old caftle; and is the capital of a government indepen¬ dent of Valentia, whofe' jurifdidion extends thirty miles in length, and fifteen in breadth. W. Long, o. 56. N.

ORILLON, in fortification, is a fmall rounding of earth, faced with a wall; raifed on the (boulder of thofe baftions that have cafemates, to cover the cannon in the retired flank, and prevent their being dif- mounted by the enemy. See Fortification. ORIOLUS, in ornithology, a genus belonging to the order of picae. The bill is conical, convex, very (harp andftraight; the fuperior mandible being much longer than the under one ; and the tongue is forked and (harp. There are 20 fp.ecies, principally diftin- guiflied by their colour. ORION, in fabulous hiftory, was the fon of Jupi¬ ter, Neptune, and Mercury. For as thefe gods were vifiting the earth, they entered the houfe of Hyrieus, a native of Tanagra, in Boeotia, under the chara&er of benighted travellers, on account of his being famed for [ 575° ] T T O R K [ 5751 ] O R K. Orion for hofpitality to ftrangers. Hyrleus treated them in I the beft manner in his,power; and even killed an ox, l| 1 ney. tj1£ on]y. one j-or entertainment. At which the gods were fo pleafed, that they offered the old man whatever he would afk; who letting them know that he defired nothing fo much as a fon, they, to gratify his wifh, caufed the ox’s hide to be brought before them, in which, having depofited their urine, they bad him keep it under ground for ten months. At the expiration of that term he dug it up, and (found in it an infant, whom he at fxrft called Urion, to exprefs his origin; but afterwards changed it to Orion. He was a remarkable hunter: and Neptune gave him the power of walking on the furface of the waters, with the fame fpeed that Iphiclus did over the ears of corn ; on which he croffed from the continent of Greece to the ifland of Chios, where attemping to j;\ violate iErope, the wife of king Oenopion, that monarch deprived him of his fight. He than travelled to Lefbos, where he was kindly received by Vulcan, who gave him a guide to the palace of the fon, where he was reftored to fight. He then made war on Oenopion ; who efcaping his vengeance by concealing himfelf under ground, he vrent to Crete, where he purfoed his favourite exercife of hunting. But having offended Diana, that goddefs put him to death, either by her arrows, or by fending a fcorpion which gave him a mortal wound; but afterwards relenting, (he prevailed on Jupiter to raife him to the fkies, where be forms a confteliation, remarkable for predicting rain and tempeftuous weather. Orion, in aftronomy, one of the conftellations of the fouthern hemifphere.—The word is formed from the Greek “ to make water;” the ancients fuppofing that it raifed tempefts at its rifing and fetting.—The flars in the confteliation Orion, in Ptolemy’s catalogue are 37, in Tycho’s 62, in the Britannic catalogue 80. ORISTAGNI, an ancient town of the ifland of Sardinia, with an archbifhop’s fee. It is pretty large and well fortified; but thinly inhabited, on account of the unhealthy air : it is feated on the weftern coaft, in a bay of the fame name, in E. Long. 8. 58. I; N.

It is divided fron the ancient king¬ dom of Golconda, by a ridge of mountains, the end of which runs a little way into the fea. It is fertile in corn and cattle, and they have feveral good towns and harbours on the coaft ; there are alfo manufactures of different kinds carried on throughout the kingdom. The prince is a Gentoo, who pays to the Great Mogul a tribute to the amount of about 12,0001. yearly. ORKNEY islands, certain iflands on the north of Scotland, from which they are feparated by a frith 20 miles in length and 10 in breadth. They are '40 in number ; but many are uninhabited, the greater part being fmall, and producing only pafturage for cattle. The principal iflands are denominated by the names of Mainland, South Ronaldjha, Snuinna, Plot- ta. Copin/ha, Strupenjba, Stronfa, Sanda, &c. the terminations in a, or ha, being generally given in the Teutonic to fuch places as are furrounded by water. The currents and tides flowing between the iflands are extremely rapid and dangerous. Near an ifland cali- Vol.VIII. ed S within were found fome i eanois. ^urnej bones and red clay ; and over it was placed a large flat ftone for the prefervation of the whole. Thefc, in all probability were Roman catacombs. In Weftra divers Danilh graves have been difcovered: in one of thefe appeared the ikeleton of a man, witlr a fword on one fide, and a Danifh ax on the other, tSome have been found buried with dogs, combs, knives, and other utenfils. In many places of the country we find round hillocks or barrows, here known by the name oi brogh, fignifying, in the Teutonic lan¬ guage, burying-place, fuppofed to have been the ce¬ meteries of the ancient Saxons. In different parts of thefe iflands we fee the remains of great buildings, believed to have been fortreffes creeled by the Danes or Norwegians when they poffeffed the country. One of thefe in the ifle of Wyre, called the cajile of Cop- pi-row, fignifying a town of fecurity, is furrounded by a foffe, and the firft floor ftill remains above ground, a perfeA fquare of ftone wall, very thick, ftrongly built, and cemented with lime, the area with¬ in not exceeding ten feet in length. Of this Coppi- row the common people relate many idle fables. In the chapel of Clet, in the ifle of Satida, there is a grave 19 feet long, *in which was found part of a man’s back bone, larger than that of a horfe. Hu¬ man bones, of nearly the fame fize, have been dug up in Weftra ; and indeed this country is remarkable for producing men of a gigantic ftature. Within the an¬ cient fabric of Lady Kirk in South Ronalfliaw, there is a ftone four feet long, and two feet broad, on which the print of two feet are engraven, fuppofed to be the place where, in times of Popery, penitents flood to do public pennance. ORLE, Orlet, or Orlo, in archite&ure, a fillet under the ovolo, or quarter round of a capital. When it is at the top or bottom of a fhaft, it is called cinc¬ ture. Palladio ufes the word orlo for the plenith of the bafis of the columns. Orle, in heraldry, an ordinary, in form of a fil¬ let, drawn round the fhield, near the edge or extre¬ mity thereof, leaving the field vacant in the middle. Its breadth is but half that of the treffure or bordure, which contains a fixth part of the fliield ; and the orle only a twelfth: befides, that the orle is its own breadth diftant from the edge of the ftiield, whereas the bor¬ dure comes the edge itfelf. The form of the orle is the fame with that of the Afield, whence it rtf»-mbles an efcutcheon. See Plate CXLIV. fig. 1. (a.) ORLEANOIS, a province of France, including the feveral diftri&s of Orleanois-Proper, Beauce-Pro- per or Chartrain, Dunois, Vendomois, Blaifois, the greateft part of Gatinois, and Perche-Gouet. The principal rivers of it are the Loire, the Loiret, the Cher, the Laconic, the Aigle, the Hyere, the Yonne, and the Evre. There are alfo fome remarkable ca¬ nals, particularly thofe of Briare and Orleans. The river Loire, and the canals drawn from thence, great¬ ly facilitate and promote the inland trade of the king¬ dom ; and particularly of this government, which lies entirely within the jurifdi&iorr of the parliament of Paris; and, befides the chief governor, has feveral fub- ordinate ones. Orleanois, in Latin Aurdianafis Ager, is bounded on the fouth by Sologne, on the north by Upper- OrleanoU. Beauce, on the eaft by Gatinois, and on the weft by ll ■; Dunois and Vendomois. The Loire divides it into 0rm nJ,i Upper and Lower; the former lying to the north, and the latter to the fouth of that river. It yields plenty of graui, wine, wood, and fruit, and abounds in cattle, game, and fifh. The principal places in it are, Orleans, from which it derives its name, and is the capital, not only of it, but of the whole government. It was anciently called Genabum or Cenabum, and af¬ terwards andand (lands 20 leagues from Paris to the fouth, on the northern bank of the Loire, over which there is here a fine ftone bridge of 16 arches, leading into a fuburb on the fouth fide of the river. In Julius Csefar’s time it was the capital of the Carnutes. Aurelian, the emperor, en¬ larged it, and gave it his name. It is one of the lar¬ ged cities in the king; but meanly built, and mod of the inhabitants are poor; though there are here feve¬ ral inferior courts of juftice, with an univerfity, at pre- » fent in no great repute; a public library; a (lately Go¬ thic cathedral, and a great number of other churches, fome of which are collegiate; a public walk, planted with feveral rows of trees; fome fugar-bakers; a ma- nufadlure of dockings and fheep-fkins; a feminary, in which divinity is taught; and a great trade in brandy, wine, fpices, and feveral manufactures, which, with many other commodities, are conveyed from hence to Paris, and other places, by means of the Loire, and the canal which takes its name from the city. Some of the trading people are very rich. The canal begins about two miles above the city; is near 18 leagues in length; and terminates on the Loing, which falls into the Seine. To the north of. the city is a foreft, the larged in the whole kingdom, belonging to the duke of Orleans; to whom the timber felled in it brings in, one year with another, about 100,000 livres. Ever fince the year 1344, this city has been a dukedom and peerage, and ufually an appennage of fome prince of the blood. Lewis XIV. gave it to his brother Philip; who begun and finiihed the canal, in whofe family it Hill continues. The duties paid by veffels going up and down the canal, amount, in fome years, to 150,000 livres. The bifliop of this city is fuffragan to the arch- bifhop of Paris, and has a revenue of 24,000 livres, otft of which his tax to Rome is 2000 florins. It is faid, a new bifliop, on the firft; day of his entering the city, has the privilege to releafe all the prifoners in it, except thofe committed for treafon. On the eighth of May, 1429, Orleans, then clofely befieged by the Englifti, was relieved by Joan of Arc, commonly call¬ ed the Maid of Orleans ; and the anniverfary of that deliverance is ftill kept here. To perpetuate the me¬ mory of it, a monument of brafs was ere£led on the bridge, which is ftill in being. ORLOPE, in the fea language, the uppermoft fpace or deck in a great ftfip, reaching from the main to the mizen-maft. In three-deck flfips, the fecond and lowed decks are fometimes called orlopes. ORMOND, the northern divifion of the county of Tipperary, in the province of Munfter in Ireland. For a long time it gave the title of earl, and afterwards of marquis and duke, to the noble family of Butler, de- feended from a filler of Thomas a Becket archbifliop of Canterbury 5, till, at the acceffion of George I. the OKNITHOIiOGY.

In that part of the country the family had great pre¬ rogatives and privileges granted by Edward III. ORMUS, an ifland of Alia, about two leagues from the main land, almoft at the mouth of the Perfian gulph. It is about fix leagues in circuit; but is quite barren, and has not a drop of frefh water. They catch excellent oyfters about the ifland; and it yields plenty of fine white fait; alfo a kind of ftiining black fand, which is ufed for dulling writings, and is tranfported in confiderable quantity to Europe. This ifland was for fome time in poffeffion of the Portuguefe, when there was a very rich and populous town upon it, where all the trade of the Indies was managed; but that has long been in ruins, and there is now nothing inhabited but the fort. ORNITHOGALLUM, Star of Bethlehem; a genus of the monogynia order, belogning to the hex- andria clafs of plants. There are feven fpecies; all of them herbaceous perennials, rifing from fix inches to three feet high, having ftalks terminated with long fpikes of hexapetalous, ftar-lhaped, white and yellow- flowers. Six of the fpecies are very hardy, and will profper in any fituation; but one, named the capenfet a native of the Cape of Good Hope, requires the affiit- ance of artificial warmth to preferve it in this country. They are all eafily propagated by off-fets from the roots. The bulbous roots of all the fpecies are nutri¬ tious and wholefome. ORNITHOLOGY. Ornithology is a fcience which treats of birds; defcribes their form, external and internal; and teaches their ceconomy and their ufes. See Bird. A bird is an animal covered with feathers; furnilh- ed with a bill; having two wings, and only two legs; with the faculty, except in a very few initances, of re¬ moving itfelf from place to place through the air.— But before proceeding to analife the charadleriftic parts of birds, it will be proper to premife an expla¬ nation of the terms ufed by naturalifts in deferibing them.

The Chin, the fpace between the parts of the lower mandible and the neck, is generally covered with feathers; but, in the cock and fome others, have car- neous appendages called wattles [palearia); in others, is naked, and furnifhed with a pouch, capable of great dilatation (facculus),'zs in the pelican and corvorants. 6. Neck, (collum), the part that connefb the head to the body, is longer in birds than any other animals; and longer in fuch as have long legs than thofe that have fhort, either for gathering up their meat from the ground, or ftriking their prey in the water, except in web-footed fowl, which are, by reverfing their bodies, deftined to fearch for food at the bottom of waters, as fwans, and the like. Birds, efpecially thofe that have a long neck, have the power of retracing, bending, or ffretching it out, in order to change their centre of gravity from their legs to their wings. , II. BOD Y. I. HEAD. 1. Bill (rojlrum), is a hard horny fubftance, con¬ fiding of an upper and under part, extending from the head, and anfwering to the mandibles in quadrupeds. Its edges generally plain and (harp, like the edge of a knife, cultrated, as are the bills of crows ; but fome- times Jerrated, as in the toucan; or jagged, as in the gannet and fome herons; or pollinated, as in the duck; or denticulated, as in the merganfers ; but always de- ftitute of real teeth immerfed in fockets. The bafe in falcons is covered with a naked (kin or cere (cera); in fome birds with a carneous appendage,, as the turkey; or a callous, as the curaffo. In birds of prey, the bill is hooked at the end, and fit for tearing; in crows, ftraight and ftrong for pick¬ ing: In water-fowl, either long and pointed, for ftri¬ king ; or flender and blunt, for fearching in the mire; or flat and broad, for gobbling. Its other ufes are for building nefts ; feeding the young; climbing, as in parrots; or, laftly, as an inftrument of defence, or of¬ fence. , 2. Nostrils, (nares), the nice inftruments of dif- perning their food, are placed either in the middle of the upper mandible, or near the bafe, or at the bale, as in parrots; or behind the bafe, as in toucans and hornbills: but fome birds, as.the gannet, are deftitute of noftrils. The noftrils are generally naked; but fometimes covered with bridles refle&ed over them, -as in crows, or hid in the feathers, as in parrots, See. The fore-part of the head is called the front (capi- Jlrum); the fummit (vertex), or the crown: the hind part, with the next joint of the neck (nucha), the nape: the fpace between the bill and the eyes, which in he¬ rons, grebes, &c. is naked, (lora), the Jlraps: the fpace beneath the eyes (gems), the cheeks. 3. Orbits, (orbit#), the eye-lids ; in fome birds naked, in others covered with (hort foft feathers. Birds have no eye-brows; but the grous kind have in lieu, a fcarlet naked (kin above, which are called fn- percilia ; the fame word is alfo applied to any line of a different colour that pafles from the bill over the 4. Ears.. Birds are deftitute of auricles or exter- 1. Confifts of the Back, (dorfurn); which is flat, ftraight, and inclines; terminated by the 2. Rump, (uropygium), furniftied with two glands, fecreting a fattilh liquor from an orifice each has, which the birds exprefs with their bills to oil or anoint the difeompofed parts of their feathers. Thefe glands are particulai-ly large in moft web-footed water-fowl; but in the grebes, which want tails, they are fmaller. 2. Breast, (pelius), is ridged and very mufcular, defended by a forked bone, (clavicula), the merry¬ thought. The (hort-winged birds, fuch as grous, See. have their breafts moft fleftiy or mufcular ; as they require greater powers in flying than the long-winged birds, fuch as gulls, herons, which are fpecifically lighter, and have greater extent of fail. 4. Belly, (abdomen), is covered with a ftrong (kin, and contains the entrails. 5. The Vent, or vent-feathers, (crijfum), which lies between the thighs and the tail. The anus lies hid in thofe feathers. III. LIMBS. r. Wings, (alee), adapted for flight in all birds except the dodo, oftriches* great auk, and the pin- guins, whofe wings are too (hort for the ufe of flying; but in the dodo and oftrich, when extended, ferve to accelerate their motion in running; and in the pinguins perform the dffice of fins, in fwimming or diving. The wings have near their end an appendage cover¬ ed with four or five feathers called the bajlard wing, (ala notba), and ahda fpuria. The lefler coverts (tellrices), are the feathers which lie on the bones of the wings. The greater coverts are thofe which lie beneath the former, and cover the quill-feathers and the feconda- ries. The quill-feathers (primores), fpring from the firft bones (digit's and metacarpi) of the wings, and are 10 in number. Qiiill-feathers are broader on their inner than exte¬ rior (ides. The fecondaries (fecondari#), are thofe that rife from the fecond part (cubitus), and are about 18 in number. Sea. I. ORNITHOLOGY. 5757 {Extcmal number, are equally broad on both fides. The primary : Parts. 8ncj fec0ndary v.ing-feathers are called retniges. A tuft of feathers placed beyond the fecondaries near the junftion of the wings with the body. This, in water-fowl, is generally longer than the fecondaries, and cuneiform. The fcapulars are a tuft of long feathers arifing near the junftion of the wings (brachia) with the body, and lie along the fides of the back, but may be eafily diftinguilhed, and raifed with one's finger. The inner coverts are thofe that clothe the under fide of the wing. The fubaxillary are peculiar to the greater Paradife. The wings of fome birds are inftruments of offence. The anhima of Marcgrave has two ftrong fpines in the front of each wing. A fpecies of plover, Edw. tab. 47. and 280. has a Angle one on each; the whole tribe of jacana, and the gambo, or fpur-winged goofe of Mr Willoughby, the fame. 2. The Tail is the direftor, or rudder, of birds in their flight; they rife, fink, or turn by its means; for, when the head points one way, the tail inclines to the other fide: it is, befides, an equilibrium or counter- poife to the other parts; the ule is very evident in the kite and fwallows. The tail confifts of ftrong feathers [reftrices), 10 in number, as in the woodpeckers, &c.; 12 in the hawk tribe, and many others; in the gallinaceous, the merganfers, and the duck kind, of more. It is either even at the end, as in moft birds; or fork¬ ed, as in fwallows; orcuneated, as in magpies, See.; or rounded, as in the purple jackdaw of Catefby. The grebe is deftitute of a tail, the rump being covered with down ; and that of the cafibwary with the fea¬ thers of the back. Immediately over the tail, are certain feathers that fpring from the lower part of the back, and are called the coverts of the tail, (uropygiam). 3. Thighs, (feviora), are covered entirely with feathers in all land-birds, except the buftards and the oftriches; the lower part of thofe of all waders, or cloven-footed water-fowl, are naked; that of all web¬ bed-footed fowl the fame, but in a lefs degree; in ra¬ pacious birds, are very mufcular. 4. Legs, (crura) ; thofe of rapacious fowls very ftrong, furnifhed with large tendons, and fitted for tearing and a firm gripe. The legs of fome of this genus are covered with feathers down to the toes, fuch as the golden eagle; others to the very nails; but thofe of moft other birds are covered with feales, or with a fkin divided into fegments, or continuous. In fome of the pies, and in all the pafferine tribe, the fkin is thin and membranous; in thofe of web-footed water-fow], flrong. The legs of moft birds are placed near the centre of gravity: in land-birds, or in waders that want the back toe, exa&ly fo; for they want that appendage to keep them ereiff. Auks, grebes, divers, and pinguins, have their legs placed quite behind, fo are necefiitated to fit ereft: their pace is aukward and difficult, walking like men in fetters : hence Linnaeus ftyles their feet pedes compedes. The legs of all cloven-footed water-fowl are long, as they muft wade in fearch of food: of the palmated, fhort, except thofe of the flamingo, the avofet, and the Courier. External 5. Feet, (pedes), in all land-birds that perch, have Part?‘ a large back toe: moft of them have three toes forward, and one backward. Woodpeckers, parrots, and other birds that climb much, have two forward, two back¬ ward; but parrots have the power of bringing one of their hind toes forward while they are feeding them- felves. Owls have alfo the power of turning one of their fore toes backward. All the toes of thefwift turn forwards, which is peculiar among land-birds: the trida&ylous woodpecker is alfo anomalous, having only two toes forward, one backward : the oftrich is another, having but two toes. 6. Toes, (digiti). The toes of all waders are divi¬ ded; but, between the exterior and middle toe, is ge¬ nerally a fmall web, reaching as far as the firft joint. The toes of birds that fwim are either plain, as in the fingle inftance of the common water-hen or galli- nule; or pinnated, as in the coots and grebes; or en¬ tirely webbed or palmated, as in all other fwimmers. All the plover tribe, or charadrii, want the back- toe. In the fwimmers, the fame want prevails among the albatrofles and auks. No water-fowl perch, ex¬ cept certain herons, the corvorant, and the fliag. 7. Claws, (ungues). Rapacious birds have very ftrong, hooked, and (harp claws, vultures excepted. Thofe of all land-birds that rooft on trees have alfo hooked claws, to enable them to perch in fafety while afleep. The gallinaceous tribe have broad concave claws for feraping up the ground. Grebes have flat nails like the human. Among water-fowl, only the fkua, Br. ZocL 11. p. 417. 3d edit. n° 234, and the black-toed gull, Br. Zool. II. p.419, 3d edit. n° 435, have ftrong hook¬ ed or aquiline claws. All land-birds perch on trees, except the ftruthious and fome of the gallinaceous tribes. Parrots climb ; woodpeckers creep up the bodies and boughs of trees; fwallows cling. All water-fowl reft on the ground, except certain herons, and one fpecies of ibis, the fpoonbill, one or two fpecies of ducks and of corvorants. IV. FEATHERS. Feathers are defigned for two ufes; as coverings from the inclemency of the weather, and inftruments of motion through the air. They are placed in fuch a manner as to fall over one another, (tegulatwi), fo as to permit the wet to run off, and to exclude the cold; and thofe on the body are placed in a quincuncial form; moft apparent in the thick-fkinned water-fowl, parti¬ cularly in the divers. The parts of a feather are, the (hafts; corneous, ftrong, light, rounded, and hollow at the lower part; at the upper, convex above, concave beneath, and chiefly compofed of a pith. 2. On each fide the (hafts are the vanes, broad on one fide, narrow on the other ; each vane confifts of a multitude of thin laminae, ftiff, and of the nature of a fplit quill. Thefe lamina are clofely braced toge¬ ther by the elegant contrivance of a multitude of fmall bridles; thofe on one fide hooked, the other ftraight, which lock into each oilier, and keep the vanes fmooth, compadl, and ftrong. The vanes near the bottom of the (hafts are foft, un- conneded, 5758 ORNITHOLOGY. Sed. III. Flight, conne&ed, and downy. 3. Feathers are of three kinds. (1.) Such as compofe inftruments of flight: as the pen-feathers, or thofe which form the wings and tail, and have a large lhaft. The vanes of the exterior fide bending downward, of the interior upwards, lying clofe on each other, fo that, when fpread, not a feather mifles its impulfe on the air. The component parts of thefe feathers are defcribed before. (2.) The feathers that cover the body, which may be properly called the plumage, have little lhaft, and much vane; and never are exerted or relaxed, ilnlefs in an¬ ger, fright, or illnefs. (3.) The Down, [pluma), which is difperfed over the whole body amidlt the plumage, is Ihort, foft, un- connefted, confifts of lanuginous vanes, and is intend¬ ed for excluding that air or water which may penetrate or efcape through the former. This is particularly ap¬ parent in aquatic birds, and remarkably fo in the an- ferine tribe. There are exceptions to the forms of feathers. The vanes of the fubaxillary feathers of the Paradife are unconne&ed, and the laminae dillant, looking like herring-bone. Thofe of the tail of the oftrich, and head of a fpecies of curaflb, curled. Thofe of the caflbwary confift of two lhafts, arifing from a common Item at the bottom : as do, at the approach of winter, (after moulting), thofe of the ptarmigans of ar&ic countries. The feathers of the pinguins, par¬ ticularly thofe of the wings, confift chiefly of thin flat drafts, and more refemble fcales than feathers ; thofe of the tail, like fplit whale-bone. Sect. II. Flight of Birds. The flight of birds is various; for, had all the fame; , none could elude that of rapacious birds. Thofe which are much on wing, or flit from place to place, often owe their prefervation to that caufe : thofe in the wa¬ ter, to diving. Kites, and many of the falcon tribe, glide fmoothly through the air, with fcarce any apparent motion of the wings. Moft of the order of pies fly quick, with a frequent repetition of the motion of the wings. The Paradife floats on the air. Woodpeckers fly aukwardly, and by jerks, and have a propenfity to fink in their progrefs. The gallinaceous tribe, in general, fly very ftrong and fwiftly ; but their courfe is feldom long, by reafon of the weight of their bodies. The columbine race is of Angular fwiftnefs; witnefs the flight of the Carrier-P^-cow. The paflerine fly with a quick repetition of ftrokes; their flight, except in migration, is feldom diftant. Among them, the fwallow tribe is remarkably agile, their evolutions fudden, and their continuance on wing long. Nature hath denied flight to the ftruthious; but flill, in running, their fhort wings are of pfe, when eredf, to colled the wind, and like fails to accelerate their motion. Many of the greater cloven-footed water-fowl, or waders, have a flow and flagging flight; but moft of the lefler fly fwiftly, and moft of them with extended legs, to compenfate the fhortnefs of their tails. Rails and gallinules, fly with their legs hanging down. Coots and grebes, with difficulty are forced from Nuptials.' the water; but when they rife, fly fwifty. Grebes, and 1 alfo divers, fly with their hind parts downwards, by reafon of the forwardnefs of their wings. Web-footed fowl are various in their flight. Several have a failing or flagging wing, fuch as gulls. Pin¬ guins, and a Angle auk, are denied the power of flight. Wild geefe, in their migrations, do not fly pell-mell, but in a regular figure, in order to cut the air with greater cafe; for example, in long lines, in the figure of a > , or fome pointed form or letter, as the ancients report that the cranes affumed in their annual migra¬ tions, till their order was broken by ftorms.

Of the Nuptials, Nidification, and Eggs of Birds. 1. Most birds are monogamous, or pair; in fpring fixing on a mate, and keeping conftant till the cares of incubation and educating the young brood is paft. This is the cafe, as far as we know, with all the birds of the firft, fecond, fourth, and fifth orders. Birds that lofe their mates early, aflbeiate with others; and birds that lofe their firft eggs will pair and lay again. The male, as well as the female, of feveral, join alternately in the trouble of incubation, and always in that of nutrition; when the young are hatched, both are bufied in looking out for and bringing food to the neftlings; and, at that period the mates of the melo¬ dious tribes, who, before, were perched on fome fprig, and by their warbling alleviated the care of the females confined to the neft, now join in the common duty. Of the gallinaceous tribe, the greateft part are po¬ lygamous, at leaft in a tame ftate; the pheafant, many of the grous, the partridges, and buftards, are mono- amous; of the grous, the cock of the wood, and the lack game, afiemble the females during the feafon of love, by their cries, Et venerem incnlam rapiunt. The males of polygamous birds negleft their young; and, in fome cafes, would deftroy them, if they met with them. The ceconomy of the ftruthious order, in this refpeeft, is obfeure. It is probable that the three fpecies in the genus oftrich are polygamous, like the common poultry, for they lay many eggs; the dodo is faid to lay but one. All waders or cloven-footed fowl are monogamous; and all with pinnated feet, are alfo monogamous, ex¬ cept the ruffs. The fwimmers or web-footed fowl obferve the fame order, as far as can be remarked with any certainty ; but many of the auks affemble in the rocks in fuch numbers, and each individual fo contiguous, that it is not poffible to determine their method in this article. It may be remarked, that the affeftion of birds to their young is very violent during the whole time of nutrition, or as long as they continue in a hclplefs ftate ; but, fo foon as the brood can fly and fhift for itfeif, the parents negleft, and even drive it from their haunts, the Sea.

The Nest of a bird is one of thofe daily miracles that from its familiarity is paffed over without regard. We flare with wonder at things that rarely happen, and negleft the daily operations of nature that ought firft to excite our admiration and claim our attention. Each bird, after nuptials, prepares a place fuited to its fpecies, for the depofiting its eggs and (heltering its little brood : different genera, and different fpecies, fet about the tafk in a manner fuitable to their feveral natures; yet, every individual of the fame fpecies col- le&s the very fame materials, puts them together in the fame form, and choofes the fame fort of fituation for placing this temporary habitation. The young bird of the laft year, which never faw the building of a neft, direfted by a heaven-taught fagacity, purfues the fame plan in the ftruclure of it, and felefts the fame mate¬ rials as its parent did before. Birds of the fame fpe¬ cies, of different and remote countries, do the fame. The fwallows of Britain, and of the remoter parts of Germany, obferve the fame order of archite&ure. The nefts of the larger rapacious birds are rude, made of flicks and bents, but often lined with fome- thing foft; they generally build in high rocks, ruined towers, and in defolate places: enemies to the whole feathered creation, they feem confcious of attacks, and feek folitude. A few build upon the ground. Shrikes, the leaft of rapacious birds, build their nefts in bufties, with mofs, wool, &c. The order of pies is very irregular in the ftrudture of their neftS. Parrots, and in fad all birds with two toes forward and two backward, lay their eggs in the hollows of trees. And moft of this order creep along the bodies of trees, and lodge their eggs alfo within them. Crows build in trees: among them, the neft of the magpie, compofed of rude materials, is made with much art, quite covered with thorns, and only a hole left for admittance. The nefts of the orioles are contrived with wonder¬ ful fagacity, and are hung at the end of fome bough, or between the forks of extreme branches. In Eu¬ rope, only three birds have penfile nefts; the common oriola, the parus pendulinus, or hang-neft titmoufe, and one more. But in the torrid zones, where the birds fear the fearch of the gliding ferpent and inqui- fitive monkey, the inftances are very frequent; a mar¬ vellous inftinft implanted in them for the prefervation of their young. All of the gallinaceous and ftruthius orders lay their eggs on the ground. The oftrich is the only excep¬ tion, among birds, of the want of natural affe&ion : “ Which leaveth her eggs in the earth, and warmeth them in the duft, and forgetteth that the foot may crufh them, or the wild beaft may break them.” The columbine race makes a moft artlefs neft, a few flicks laid acrofs may fuffice. Moft of the pafferine order build their nefts in fhrubs or bufties, and fome in holes of walls or banks. Vol. VIII. 2 Several in the Torrid Zone are penfile from the Eggs, boughs of high trees; that of the taylor-bird, a won- drous inftancef. Some of this order, fuch as larks, f See Mo- and the goatfucker, on the ground. Some fwallows ToAC ILL** make a curious plafter-neft beneath the roofs ofn 5’ houfes ; and an Indian fpecies, one of a certain gluti¬ nous matter, which are colle&ed as delicate ingre¬ dients for foups of Chinefe epicures. See the article Birds-AV/?/. Moft of the cloven-footed water-fowl, or waders, lay upon the ground. Spoonbills and the common heron build in trees, and make up large nefts with flicks, &c. Storks build on churches, or the tops of houfes. Coots make a great neft near the water-fide. Grebes, in the water, a floating neft, perhaps ad¬ hering to fome neighbouring reeds. Web-footed fowl breed on the ground, as the avo- fet, terns, fome of the gulls, merganfers, and ducks: the laft pull the down from their breafts, to make a fofter and warmer bed for their young. Auks and guillemots lay their eggs on the naked (helves of high rocks ; pinguins, in holes under ground : among the pelicans, that which gives name to the genus, makes its neft in the defart, on the ground. Shags, fometimes on trees ; corvorants and gannets, on high rocks, with flicks, dried algse, and other courfe ma¬ terials. 3. Rapacious birds, in general, lay few Eggs; eagles, and the larger kinds, fewer than the Itfler. The eggs of faleons and owls are rounder than thofe of moft other birds ; they lay more than fix. The order of pies vary greatly in the number of their eggs. Parrots lay only two or three white eggs. Crows lay fix eggs, greenifti, mottled with dulky. Cuckoos, as far as we can learn, two. Woodpeckers, wryneck, and kingsfifher, lay eggs of a clear white and femi-tranfparent colour. The woodpeckers lay fix, the others more. The nuthatch lays often in the year,eight at a time, white, fpotted with brown. The hoopoe lays but two cinerous eggs. The creeper lays a great number of eggs. The honeyfucker, the leaft and moft defencelefs of birds, lays but two : but Providence wifely prevents the extintftion of the genus, by a fwiftnefs of flight that eludes every purfuit. The gallinaceous order, the moft ufeful of any to mankind, lay the moft eggs, from 8 to 20. Benigtia circa hoc natura, innocua et efculenta aninialia fa- cundageneravit, is a fine obfervation of Pliny. With exception to the buftard, a bird that hangs be¬ tween the gallinaceous and the waders, which lays only two. The columbine order lays but two white eggs; but the domeftic kind, breeding almoft every month, fup- ports the remark of the Roman naturalift. All of the pafferine order lay from four to fix eggs ; except the titmice and the wren, which lay 15 or 18, and the goatfucker, which lays only two. The ftruthious order, which confifts but of two genera, difagree much in the number of eggs : the oftrich laying many, as far as 50 j the dodo, but one, 32 N The 576° Syftem. ORNITHOLOGY. Sea. IV. The cloven-footed water-fowl, or waders, lay, in general, four eggs: The crane and the Norfolk plo¬ ver, feldom more than two. All thofe of the fnipe and plover genus are of a dirty white, or olive fpotted with black, and fcarce to be diftinguilhed in the holes they lay in. The bird called the Land Rail, (an am¬ biguous fpecies,) lays from 15 to 20. Of birds with pinnated feet, the coot lays feven or eight eggs, and fometimes more. Grebes, from four to eight, and thofe white. The web-footed, or fwimmers, differ in the number of their eggs. Thofe which border on the order of waders, lay few eggs ; the avofet, two ; the flamin¬ go, three; the albatrofs, the auks, and guillemots, lay only one egg a-piece : the eggs of the two laft are of a fize ftrangely large in proportion to the bulk of the birds. They are commonly of a pale green colour, fpotted, and ftriped fo varioufly, that not two are alike ; which gives every individual the means of diftinguifliing its own on the naked rock, where fuch multitudes aflemble. Divers, only two. Terns and gulls lay about three eggs, of a dirty olive, fpotted with black. Ducks lay from eight to twenty eggs; the eggs of all the genus~are of a pale green, or white, and un- fpotted. Pinguins probably lay but one egg. Of the pejican genus,'the gannet lays but one egg; the (hags or corvorants, fix or feven, all white ; the laft, the mod oblong of eggs. A minute account of the eggs of birds might occupy a treatife of itfelf. This is only meant to (hew the great conformity natures obferves in the fhape and colours of the eggs of congenerous birds; and alfo, that {he keeps the fame uniformity of colour in the eggs, as in the plumage of the birds they belong to. Zinanni publifhed, at Venice, in 1737, a treatife on eggs, iiluftrated with accurate figures of 106 eggs. Mr Reyger of Dantzick publiftied in 1766, a pofthumous work by Klein, with 21 plates, ele¬ gantly coloured: but much remains for future wri¬ ters. Sect. IV. Syjlem. Considering the many fyftems that have been offered to the public of late years, Mr Pennant gives the preference to that compofed by Mr Ray in 1667, and afterwards publiftied in 1678 ; but obferves, at the fame time, that it would be unfair to conceal the writer, from whom our great countryman took the original hint of forming that fyftem which has proved the foundation of all that has been compofed fince that period. It was a Frenchman, Belon of Mans, wfio firft at¬ tempted to range birds according to their natures; and performed great matters, confidering the unenlightened age he lived in ; for his book was publiftied in 1555. His arrangment of rapacious birds is as judicious as that of the lateft writers. For his fehond chapter treats of vultures, falcons, ftirikes, and owls : in the two next, he paffes over to the web footed water-fowl, and to the cloven-footed : in the fifth, he includes the gallinaceous and ftruthious; but mixes with thefn the plovers, buntings, and larks : in the fixth are the pies, Syftem. pigeons, and thrufties ; and the feventh takes in the “ reft of.the pafferine order. Notwithftaning the great defe&s that every natu- ralift will at once fee in the arrangement of the leffer birds of this writer, yet he will obferve a reditude of intention in general, and a fine notion of fyftem, which was left to the following age to mature and bring to perfeftion. Accordingly, Mr Ray, and his illuftrious pupil the Hon. Francis Willughby, affumed the plan; but, with great judgment, flung into their proper .Rations and proper genera thofe which Belon had confufedly mixed together. They formed the . great divifion of terreftrial and aquatic birds; they made every fpecies occupy their proper place, con- fulting at once exterior form and natural habit. They could not bear the affedted intervention of aquatic birds in the midft of terreftrial birds. They placed the laft by themfelves; clear and diftinft from thofe whofe haunts and ceconomy were fo different. The fubjoined fcheme of arrangement by Mr Pen¬ nant, is introduced with the following obfervations. “ Mr 'Ray’s general plan is fo judicious, that to me Pennant’s it feems fcarce poffible to make any change in it for Genera of the better: yet, notwithftanding he was in a manner the founder of fyftematic Zoology, later difcoveries have made a few improvements on his labours.

The flowers are univerfally of the papilionaceous or butterfly kind, confiding each of four irregular petals, /. e. a flandard, two wings, and a keel ; and are all fucceeded by long taper feed- pods, furnilhing plenty of ripe feed in autumn; by which the plants may be propagated abundantly, as alfo by parting the roots. The Scots Highlanders have a great efteem for the tubercles of the roots of the tuberofus, or fpe¬ cies fometimes called ’wood-pea.

ORPHAN, a fatherlefs child, or minor; or one that is deprived both of father and mother. ORPHEUS, a celebrated poet and mufician of an¬ tiquity. His reputation was edablifhed as early as the time of the Argonautic expedition, in which he was himfelf an adventurer ; and is faid by Apollonius Rhodius not only to have incited the Argonauts to row by the found of his lyre, but to have vanquifhed and put to filence the firens by the fuperiority of his drains. Yet, notwithdanding the great celebrity he had fo long enjoyed, there is a paflage in Cicero, which fays, that Aridotle, in the third book of his Poetics, which is now lod, doubted if fuch a perfon as Orpheus ever exijled. But as the^work of Cicero, in which this paffage occurs, is in dialogue, it is not eafy to difeover what was his own opinion upon the fubjed, the words ci:ed being put into the mouth of Caius Cotta. And Cicero, in other parts of his wri¬ tings, mentions Orpheus as a perfon of whofe ex,id- 32 N 3 ence O R P [ 5762 ] O R P Orpheus, ence he had no doubts. There are feveral ancient au¬ thors, among whom is Suidas, who enumerates five perfons of the name of Orpheus> and relates fome par¬ ticulars of each. And it is very probable that it has fared with Orpheus as with Hercules, and that wri¬ ters have attributed to one the actions of many. But, however that may have been, we fliall not attempt to colleft all the fables that poets and mythologifts have invented concerning him ; they are too well known to need infertion here. We fhall, therefore, in fpeak- ing of him, make ufe only of fuch materials as the belt ancient hiftorians, and the mod refpeftable wri¬ ters among the moderns, have furnilhed towards his hiftory. Dr Cudworth, in his Intclkttual Syjlem, after exa¬ mining and confuting the obje&ions that have been made to the being of an Orpheus, and with his ufual learning and abilities clearly eftablilhing his exift- ence, proceeds, in a very ample manner, to fpeak of the opinions and writings of our bard, whom he re¬ gards not only as the firft mufician and poet of anti¬ quity, but as a great mythoiogift, from whom the Greeks derived the Thracian religious rites and my- - fteries. “ It is the opinion (fays he) of fome eminent phi- lologers of later times, that there never was any/uch perfon as Orpheus, except in Fairy-land ; and that his whole hiftory was nothing but a mere romantic al¬ legory, utterly devoid of truth and reality. But there is nothing alleged for this opinion from antiquity, ex¬ cept the one paffage of Cicero concerning Ariftotle : who feems to have meant no more than this, that there was no fuch poet as Orpheus, anterior to Ho¬ mer; or that the verfes vulgarly called Orphical, were not written by Orpheus. However, if it (hould be granted that Ariftotle had denied the exiftence of fuch a-man, there feems to be no reafon why his Angle te- ftimony fhould preponderate againft the univerfal con- fent of all antiquity : which agrees, that Orpheus was the fon of Oeager, by birth a Thracian, the father or chief founder of the mythological and allegorical theology amongft the Greeks, and of all their moft facred religious rites and myfteries ; who is common¬ ly fuppofed to have lived before the Trojan war, that is, in the time of the Ifraelitifli judges, or at lead to have been fenior both to Hefiod and Homer ; and to have died a violent death, moft affirming that he was torn in pieces by women. For which reafon, in the vifion of Herus Pamphylius, in Plato, Orpheus’s foul palling into another body, is faid to have chofen that of a fwan, a reputed mufical animal, on account of the great hatred he had conceived for all women, from the death which they had infli&ed on him. And the hi- ftoric truth of Orpheus was not only acknowledged by Plato, but alfo by Ifocrates, who lived before A- riftotle, in his oration in praife of Bufiris; and con¬ firmed by the grave hiftorian Diodorus Siculus, who fays, that Orpheus diligently applied himfelf to litera¬ ture, and when he had learned or the mythological part of theology, he travelled into E- gypt, where he loon became the greateft proficient among the Greeks in the myfteries of religion, theolo¬ gy, and poetry. Neither was his hiftory of Orpheus contradi&ed by Origen, when fo juftly provoked by Celfus, who had preferred him to our Saviour 5 and, according to Suidas, Orpheus the Thracian was the Orpheus, firft inventor of the religious myfteries of the Greeks, u and that religion was thence called Threjkeia, as it was a Thracian invention. On account of the great anti¬ quity of Orpheus, there have been numberlefs fables intermingled with his hiftory, yet there appears no rcafon that we ffiould difbelieve the exiftence of fuch a man.” The biffiop of Gloucefter fpeaks no more doubtful¬ ly of the exiftence of Orpheus, than of Homer and Hefiod, with whom he ranks him, not only as a poet, but alfo as a theologian, and founder of reli¬ gion. The family of Orpheus is traced by Sir Ifaac New¬ ton for feveral generations : “ Sefac palling over the Hellefpont, conquers Thrace ; kills Lycurgus, king of that country ; and gives his kingdom and one of his finging-women to Oeagrus,the fon of Tharops, and father of Orpheus; hence Orpheus is faid to have had the mufe Calliope for his mother.” He is allowed by moft ancient lauthors to have ex¬ celled in poetry and mufic, particularly the latter; and to have early cultivated the lyre, in preference to every other inftrument: fo that all thofe who came after him were contented to be his imitators; whereas he adopted no model, fays Plutarch; for before his time no other mufic was known, except a few airs for the flute. Mufic was fo clofely conneded in ancient times Burnet's with the moft fublime fciences, that Orpheus united it Hi/?- of not only with philofophy, but with theology. He ab- Mujic, ftained from eating animal food; and held eggs in ab- P- horrence as aliment, being perfuaded that the egg fubfifted before the chicken, and was the principle of all exiftence: both his knowledge and prejudices, it is probable, were acquired in Egypt, as well as thofe of Pythagoras many ages after. With refpeft to his abftaining from the flefli of oxen, Gefner fuppofes it may have proceeded from the veneration ftiewn to that animal fo ufeful in tillage, in the Eleufinian myfteries, inftituted in honour of Ceres, the goddefs of agriculture. He might have added that, as thefe myfteries were inftituted in imi¬ tation of thofe eftablilhed in Egypt in honour of Ofiris and Ifis, this abftinence from animal food was of the the origin, and a particular compliment, to Apis. But likeabbe Fraguier, in an ingenious diflertation upon the Orphic Life, gives ftill more importance to the prohi¬ bition ; for as Orpheus was the legiflator and huma- nizer of the wild and favage Thracians, who were ca- nibals, a total abolition of eating human flefli could only be eftablifhed by obliging his countrymen to ab- ftain from every thing that had life. With refpeft to theology, Diodorus Siculus tells us, that his father Oeagrus gave him his firft inftruc- tions in religion, Imparting to him the myfteries of Bacchus, as they were then pradlifed in Thrace. He became afterwards a difciple of the Idas! Daftyli in Crete, and there acquired new ideas concerning reli¬ gious ceremonies. But nothing contributed fo much to his fkill in theological matters, as his journey into Egypt; where being initiated into the myfteries of I- fis and Ofiris, or of Ceres and Bacchus, he acquired a knowledge concerning initiations, expiations, fune¬ ral rites, and other points of religious worfhip, far fu- perior to any on« of bis age and country. And being much O R P [ 5763 ] O R P Orphcns. much connefled with the defcendants of Cadmus, the ties themfelves, whom he rendered fo far propitious to - founder of Thebes in Beotia, he refolved, in order to his intreaties as to reftore to him Eurydice, upon con-' honour their origin, to tranfport into Greece the dition that he would not look at her till he had quit- whole fable of Ofiris, and apply it to the family of ted their dominions; a bleffing which he foon forfeit- Cadmus.

Thus Orpheus, who was held in great veneration at the Grecian Thebes, of which he was become a citizen, admirably adapted this fable, and render it refpeftable, not only by his beautiful verfes, and manner of finging them, but by the reputation he had acquired of being profoundly /killed in all religious concerns. At his return into Greece, according to Paufanias, he was held in the higheft veneration by the people, as they imagined he had difcovered the fecret of expia¬ ting crimes, purifying criminals, curing difeafes, and appeafing the angry gods. He formed and promul¬ gated an idea of a hell, from the funeral ceremonies of the Egyptians, which was received throughout all Greece. He inftituted the mvfteries and worfliip . „ of Hecate among the Eginetes, and that of Ceres at Eurydice from hell, by his great ftill in medicine, with Sparta. which he prolonged her life, or, in other words, Juftin Martyr fays, that he introduced among the fnatched her from the grave. iEfculapins, and other Greeks near 360 gods; Hefiod and Homer purfued phyficians, have been faid to have raifed from the his labours, and followed the fame clue, agreeing in dfad» thofe whom they had recovered from dangerous the like dodlrines, having all drank at the fame E- difeafes. gyptian fountain. The bifhop of Gloucefter, in his learned, ample, Profane authors look upon Orpheus as the inventor and admirable account of the Eleufinian myfteries, of that fpecies of magic called evocation of the manes, fays» “ WhiIe thefe myfteries were confined to Egypt or raifing ghofts ; and indeed the hymns which are at- ^eir native country, and while the Grecian lawgivers tributed to him are moftly pieces of incantation, and weut thither to be initiated, as a kind of defignation real conjuration.

He there fancied he faw his and continued even after the myfteries were introdu- dear Eurydice, and at his departure flattered himfelf ced into Greece, as appears by the fables of Hercules, that (he followed him ; but upon looking behind him, Caftor, Pollux, and Thefeus’s defeent into hell; but and not feeing her, he was fo afflidled, that he foon the allegory was fo circumftanced, as to difeover the died of grief. truth concealed under it. So Orpheus is faid to get There were perfons among the ancients who made t0 ^7 the P°wer of his harp : public profeffion of conjuring up ghofts, and there Tbr'eUia fretus cithard, fidibufque canons. were temples where the ceremony of conjuration was Virg.

Paufanias fpeaks of that which was That is, in quality of lawgiver; the harp being the in Tbefprotia, where Orpheus went to call up the known fymbol of his laws, by which he humanized a ghoft of his wife Eurydice.

Periander, the tyrant of Many ancient writers, in fpeaking of his death, re- Corinth, vifited the Thefprotians, to confult his wife late, that the Thracian women, enraged at being about fomething left with her in truft ; and we arc abandoned by their hufbands, who were difciples of told by the hiftorians, that the Lacedaemonians ha- Orpheus, concealed themfelves in the woods, in order ving ftarved Paufanias their general to death, in the to fatiate their vengeance; and, notwithftandingthey temple of Pallas, and not being able to appeafe his poftponed the perpetration of their defign fome time manes, which tormented them without intermiffion, thro’ fear, at length, by drinking to a degree of in- fent for the magicians from Theflaly, who, when they toxication, they fo far fortified their courage as to put had called up the ghofts of his enemies, fo effeflually him to death. And Plutarch aflures us, that the Thra- put to flight the ghoft of Paufanias, that it never more cians ftigmatized their women, even in his time, for chofeto ihew its face. the barbarity of this a&ion. The poets have embellifhed this ftory, and given Our venerable bard is defended by the author of the to the lyre of Orpheus, not only the power of filen- Divine Legation, from fome infinuations to his difad- cing Cerberus, and of fufpending the torments of vantage in Diogenes Laertius. “ It is true (fays he) Tartarus, but alfo of charming even the infernal dei- if uncertain report was to be believed, the myfteries Orpheus. Orpheus. O R P [ 5464 ] O R R were corrupted very early; for Orpheus himfelfisfaid to have abufed them. But this was an art the de¬ bauched myftae of later times employed to varnifli their enormities ; as the detefted pederafts of after-ages, fcandalized the blamelefs Socrates. Befides, the ftory is fo ill laid, that- it is detefted by the furetl records of antiquity: for in confequence of what they fabled of Orpheus in the myfteries, they pretended he was torn in pieces by the women; whereas it appeared from the infeription on his monument at Dium in Macedonia, that he was ftruck dead with light¬ ning, the envied death of the reputed favourites of the gods.” This monument at Dium, confifting of a marble urn on a pillar, was ftill to be feen in the time of Pau- fanias. It is faid, however, that his fepulchre was removed from Libethra, upon mount Olympus, where Orpheus was born, and from whence it was transfer¬ red to Dium by the Macedonians, after the ruin of Libethra by a fudden inundation which a dreadful Ilorm had occafioned. This event is very minutely re¬ lated by Paufanias. Viigil bellows the lirft place in his Elyfium upon the legiflators, and thofe who brought mankind from a fate of nature into fociety: Magnanimi heroes, nati meliorihus annis. At the head of thefe is Orpheus, the moll renowned of the European law-givers, but better known under the charafler of poet: for the firft laws being written in meafure, to allure men to learn them, and, when learnt, to retain them, the fable would have it, that by the force of harmony Orpheus foftened the favage inhabitants of Thrace: Threicius longa cum vejle facer Jos Obloquitur numeris feptum-diferimna vocum : Jamque eadem digitis, jam peBine pul fit eburno. Mis. lib. vi. ver. 645. The feven firings given by the poet in this paflage to the lyre of Orpheus, is a circumftance fomewhat hiilorical. The firft Mercurean lyre had, at moll, but four firings. Others were afterwards added to it by the fecond Mercury, or Amphion : but according to feveral traditions preferved by Greek hiftorians, it was Orpheus who completed the fecond tetrachord, which extended the fcale to a heptachord, or feven funds, implied by the feptem diferimina vocum. For the afiertion of many writers, that Orpheus added two new firings to the lyre, which before had feven, clafhes with the claims of Pythagoras to the invention of the o&achord, or addition of the found ptofambano- vienos to the heptachord, of which almoft all antiqui¬ ty aflows him to have been the inventor. And it is .not eafy to fuppofe, that the lyre fhould have been reprefented in ancient fculpture with four or five firings only, if it had had nine fo early as the time of Or¬ pheus, who flourifhed long before'fculpture was known in Greece. See the article Lyre. With refpevl to the writings of Orpheus,he is men¬ tioned by Pindar as author of the Argonautics, and Herodotus fpeaks of his Orphics. His hymns, fays Paufanias, were very fhort, and but .few in dumber: the Lyeomides, an Athenian family, knew them by heartland had an exclufive privilege of finging them, and thofe of their old poets, Mufasus, Onomacritus, Pamphus, and Olen, at the celebration of the Eleufi- Orpheut nian myfleries : that is, the priefthood was hereditary „ ill in this family. °rrerr- Jamblicus tells us, that the poems under the name of Orpheus were written in the Doric dialed, but have fince been tranfdialeded, or modernifed. It was the common opinion iq antiquity that they were ge-j nuine; but even thofe who doubted of it, gave them to the earlidt Pythagoreans, and fome of them to Pyr thagoras himfelf, who has frequently been called the follower of Orpheus, and been fuppofed to have adop¬ ted many of his opinions.

In OKS [ 57 Orrery In ordef to this we muft compare, and find out the Oif to Proponion, which the periodical times, or revolutions r at°' of the primary planets, bear to that of the earth: And they are fueh as are exprefied in the table below, where the iiril column is the time of the earth’s period in days and decimal parts; the feqond, that of the planets ; the third and fourth are numbers in the fame proportion to each other : as, 365,25 : 88 $ : : 83 : 20, for Mercury. 365,25 : 224,7 $ : : 52 : 32, for Venus. 365,25 ; 686,9: j1 : : 40 : 75, for Mars. 365,25 : 4332,5 m = : 7 : 83’ for Jupiter. 365,25 : 10759,3 f> : : 5-: 148, for Saturn.

Thefe arbors, with their wheel, are to be placed in a box', of an adequate fize, in a perpendicular pofi¬ tion : the arbor of fixed wheels to move in pivots at the top and bottom of thebox; and the arbor of move- able wheels to go thro’ the top of thebox, to a proper height, on the top of which is to be placed a round ball, gilt with gold to reprefent the fun.

For while the fixed wheel CK moves its equal CP once round, the wheel AM will move AN a little more than four times round, and fo will nicely exhibit the motion of Mercury; and the wheel FG will turn the wheel FS about—— round, and fo 29’5 will truly reprefeut the motion of Saturn : and the fame is to be obferved of all the reft.

This plant grows upon moifl: foils, where the ground can be flowed over with water after it is come up. So that whoever would cultivate it in this country fhould fovv the feeds upon a hot-bed ; and when the plants are come up, they fhould be removed into pots filled with light rich earth, and placed in pans of water, which fhould be plunged into a hot-bed ; and, as the water wades, it mud from time to time be renewed again. In July thefe plants may be fet abroad in a warm fi- tuation, dill preferving the water in the pans, other- wife they will not thrive; and, toward the latter end of Augud, they will produce their grain, which will ripen tolerably well, provided the autumn proves fa¬ vourable—The leaves of rice are long, like the reed, and flefliy; the flowers blow on the top, like barley; but the feed which follows is difpofed in cluders, each of which is inclofed in a yellow hufk, ending in a fpiral threa’d. The feed is oblong, or rather oval and white. Rice is the chief commodity and riches of Damieta in Egypt. Dr Haflclquid gives the following de- fcription of the manner in which they drefs and fepa- rate it from the hulks. “ It is pounded by hollow iron pedles of a cylindrical form, lifted up by a wheel worked by oxen. A perfon fitting between the two pedles, puflies forward the rice when the pedles are Oryza, rifing; another fifts, winnows, and lays it under the (^orn~ pedles. In this manner they continue working it un¬ til it is entirely free from chaff and hulks. When clean, they add a 30th part of fait, and pound them together ; by which the rice, formerly grey, becomes white. After this purification, it is palled through a fine fieve to part the fait from the rice; and then it is ready for fale.” Damieta fells every year 60,800 facks of rice, the greateft part of which goes to Turky, fome to Leghorn, Marfeilles, and Venice. Rice, according to Dr Cullen, is preferable to all other kinds of grain, both for largenefs of produce, quantity of nourifhment, and goodnefs. This, he fays, is plain from macerating the different grains in water ; for, as the rice fwells to the larged fize, fo its parts arc more intimately divided. Rice is faid to affedl the eyes; but this it purely prejudice. Thus it is alleged a particular people of Afia, who live on this grain, are blind-eyed : but if the foil be fandy, and not much covered with herbage, and as thefe people are much employed in the field, this affe&ion of their eyes may be owing to the drong reflexion of the rays of light from this fandy foil; and our author is the more in¬ clined to this opinion, becaufe no fuch effe& is ob- ferved in Carolina, where rice is very commonly ufed. Dr Percival informs us, that as a wholefome nouridi- ment, rice is much inferior to falep. He digeded feveral alimentary mixtures prepared of mutton and water, beat up with bread, fea-bifeuit,falep, rice flour, fago powder, potato, old cheefe, &c. in a heat equal to that of the human body. In 48 hours they had all acquired a vinous fmell, and were in bride fermentation, except the mixture with rice, which did not emit many air- bubbles, and was but little changed. The third day feveral of the mixtures were fweet, and continued to ferment; others had lod their intedine motion, and were four; but the one which contained the rice was become putrid. From this experiment it appears that rice, as an aliment, is flow of fermentation, and a very weak corredlor of putrefaction. It is therefore an im¬ proper diet for hofpital patients ; but more particu¬ larly for failors, in long voyages, becaufe it is inca¬ pable of preventing, and will not contribute much to check the progrefs of, that fatal difeafe, the fea-feurvy. Under certain circumdances, rice feems difpofed of it- felf, without mixture, to become putrid. For by long keeping, it fometimes acquires an offen five foe tor. Nor, according to our author, can it be confidered as a very nutritive kind of food, on account of its difficult fo- lubility in the domach. Experience confirms the truth of this conclufion; for it is obferved by the planters in the Wed-Indies, that the negroes grow thin, and are lefsable to work, whild they fubfid upon rice.

OSNABURG, a bilhopric of Germany, fituated in the centre of the circle of Weftphalia between the Wefer and the Ems, having Minden on the eaft, Munfter on the weft, Diephok on the north-eaft, and Ravehfburg on the fouth weft. It is about 45 miles long and 25 broad, producing fome rye, feveral forts of turf, coals, marble, and good pafturage. The in¬ habitants, who are a mixture of Proteftants and Ro¬ man-catholics, breed a confiderable number of cattle, efpecially hogs, of which they make excellent bacon land hams; but a great part of the country confifts of heaths. By the treaty concluded here in 1648, the bilhopric was to be an alternative between the Roman- catholics and Lutherans ; and the Lutheran bilhop was to be a younger prince of the houfe of Brun- fwic Lunenburg, or, on failure thereof, of Brun- fwic Wolfenbuttle. In confequence of this fettle- ment, his Britannic majefty’s fecond fon is now bilhop of Ofnaburg. The bilhop is able to raife 2500 men, his revenue being between 20,000 and 30,000 1. The chief manufactures of the country are a coarfe kind of linen cloth and yarn, which are faid to bring into it annually above 1,000,000 of rix-dollars. There are alfo fome woollen manufactures in Ofnaburg and Bramfche. The land-eftates of the bilhopric, are the chapter, the knights, and the four towns. The diets are held at Ofnaburg, when called together by the bilhop. The count of Bar is hereditary fenefchal or fteward, and prefident of the college of knights. The bilhop is a prince of the empire; and, in the matricula, is rated at 6 horfe and 36 foot, or 216 florins monthly in lieu of them. To the chamber of the empire he contributes, each term, 81 rix- ‘ dollars, 14 kruitzers and a half. The capital of this bilhopric is Osnabrug, or Ofnalruck. It was formerly an imperial city, and one of the Hanfe-tovvns; but is now fubjeCI to the bilhop, though it ftill enjoys many privileges, and a revenue of about 8000 or 9000 rix-doliars. It has its name from a bridge over the river Hafe, or Ofe, which divides it into the Old and New Town, and Hands 67 miles Weft of Hanover, and 30 north-eaft of Munfter, being furrounded with walls and ditches, but commanded by a mountain within cannon-Ihot.

He was fgcretary at Rome to M. de Foix, archbilhop of Touloufe; to car¬ dinal Efte ; and afterwards to cardinal de Joyeufe, by the French king’s exprefs command. After rifing to the higheft dignities both in church and ftate, in 1599 he was created a cardinal by pope Clement VIII. He died in 1604. A0 eminent French writer gives him the following chara&er. “ He was a man of prodi¬ gious penetration; applied himfelf fo clofely to affairs, and efpecially was fo judicious in forming his refolu- tions, that it is almoft impoffible to find out one falfe ftep in the many negociations in which he was con¬ cerned.” His works, and efpecially his letters, have been much efteemed in the learned world. OSSIAN, the fon of Fingal *, a celebrated Celtic * See the ar- poet, who flourifhed about the end of the third and dele Fin- beginning of the fourth century. Several incidents in * bis poems point out this as his tera: particularly thepjix. engagement of Fingal with Caracul, or Caracalla, the fon of the emperor Severus, ftyled by Oflian, The Son of the King of the ’world; and another expedition under the condud of Ofcar, again ft the ufurper Caraufius, the Caros of Oflian, who aflumed the purple in the year 287. This correfponds pretty nearly with the ac¬ count given by the Irifh hiftories, which place the death of Fingal in the year 283, and the death of Of- car (who died many years before his father Oflian) in the year 296. At fuch a diftance of time, it cannot be expec¬ ted we fliould be able to give a particular account of the life of Oflian. The iirft expedition on which his father fent him was, to raife a (lone on the banks of Crona, to perpetuate the memory of a viftory which the king of Morven had obtained at that place. The Highlanders talk of this as being emblematical of that immortality which heroes were to receive from his future compofitions. In this expedition he was ac¬ companied by Tofcar, father to the beautiful Malvina, the amiable companion of his grief, after the death of her beloved Ofcar, his fon. It appears from his poems, that, in one of his early expeditions to Ireland, he had 32 O fallen OSS f Fingal, ©ffian. fallen in love with and married Evirallin, daughter to Branno, petty king of Lego. “ I went in fuitof the maid of Lego’s fable furge ; twelve of my people “ were there, the fons of ftreamy Morven.

Not eafy to win is the maid that has denied “ the bine-eyed fons of Erin. But bleft be thou, O “ fon of Fingal! happy is the maid that waits thee. “ Though twelve daughters were mine, thine were the “ choice, thou fon of fame.’—Then he opened the hall “ of the maid ; the dark-haired Evirallin This Eviraliin was the mother of his fon Ofcar, whofe ex¬ ploits he celebrates in many of his poems, and whofe death he laments in the firfl book of Temora. Eviral¬ lin died fome time before Ofcar, (FinG. B. iv.), who feems to have been her only child ; and Offian did not marry afterwards: fo that his pofterity ended in the death of Ofcar; who feems to have died as he was a- bout to be married to Malvina, the daughter of Tof- car. Several of her lamentations for her lover are re¬ corded by Offian, which paint her grief in the ftrong- eft and moll beautiful colours.^—“ It is the voice of “ my love! few are his vifits to my dreams.—But “ thou dwelled in the foul of Malvina, fon of mighty “ Offian.

The principal refidence of Offian was in the vale of Cona, now Glenco, in Argyldhire. See Fingal, in APPENDIX. His poems relate many of his expeditions to Ire¬ land, Scandinavia, Clyde, and Tweed or Teutha. His exploits on thefe occafions, after making a large allowance for poetical exaggeration, {hew him to have been no lefs a warrior than a poet. See Ossian’s Works, in the poems Calthon and Colmal, Latbmon, Berratlmn, &c. By thefe expeditions, which were al¬ ways undertaken for the relief of the didreffed, the mind of Offian feems to have been cultivated and en¬ larged beyond what is ufuslly to be met with in fo rude a period of foeiety as that in which he lived. His poems breathe throughout, fuch a fpirit of generofity and tendernefs, efpecially towards the fair fex, as is [ 57^ ] OSS your courfe.

The current tradition is, that he died in the houfe of a Culdee, called the Son of Fllpin, with whom he is faid to have held feveral con¬ ferences about the doftrines of Chridianity. One of thefe dialogues is dill preferved, and bears the genuine marks of a very remote antiquity; (Differtation pre¬ fixed to Ojjians Works.) Several of Offian’s poems are addreffed to this fon of Alpin, who was probably one of thofe Chridians whom the perfecution under Dioclefian had driven beyond the pale of the Roman empire. The poems of Offian, tho’always held in the highed; edeem by thofe who knew them, were allowed to remain in the obfeurity of their original Galic, till Mr Mac- pherfon, about 20 years ago, tranflated a colle&ion of them into Engliffi, which immediately attrafled tire at¬ tention of every perfon who had a true tade for poetry. Dr Blair, in particular, introduced thefe poems into the world with thofe critical remarks, which do no lefs honour fo himfelf than to the poet. According to that eminent critic, the two great charadteridics of Of¬ fian’s poetry are tendernefs and fublimity. Offian is, perhaps, the only poet who never relaxes, or lets him¬ felf down into the light and amufing drain. He moves perpetually in the high region of the grand and pathe¬ tic. The events which he records are all fe -'ous and grave ; the feenery wild and romantic. We find not in him an imagination that fports itfelf and drefles out gay trifles to pleafe the fancy. His poetry, more per- feldom or never to be met with in the compofitions of haps than that of any other, deferves to be dyled the other poets who lived in a more advanced flat^of lifation. He lived to an extreme old age; having fur- vived all his family and friends, many of whom perifli- ed by a fatal accident, recorded in one of his poems •' See Galic called the Fall o/Tura*. Malvina, alone, the love of Antiquities, fois f0n Ofcar, remained with him till within a few years of his death, and paid him every attention that could be expedled' from the tender relation in which fhe flood to him. To her he addrefies many of his poems, which feem to have been compofed for the mofl part in his old age. Her death is pathetically lamented by him in the poem of Berrathon : towards the clpfe of which, lie gives the prefages of his own departure; an event which he often vvifhes for, under the blindnefs and other calamities of his declining years. “ Roll c‘ on, ye. dark-brown yearsj for ye bring no joy on poetry of the heart. It is a heart penetrated with noble fentiments, with fublime and tender paffions; a heart that glows and kindles the fancy ; a heart that is full, and pours itfelf forth. Of all the great poets, Ho¬ mer is the one whofe manner and whofe times come the nearefl to Offian’s. Homer’s ideas were more en¬ larged, and his charafters more diverfified. Offian’s ideas fewer, but of the kind fitteft for poetry; the bravery and generofity of heroes, the tendernefs of lo¬ vers, and the attachment of friends. Homer is dif* fufe; Offian abrupt and concife. His images are a blaze of lightning, which flafii and vanifh. Homer has more of impetuofity and fire; Offian of a folemn and awful grandeur. In the pathetic, Homer has great power; but Offian exerts that power much oftener, and has the chara&er of tyidernefs more deeply im¬ printed G/ITaBf Offian.

With regard to dignity of fentiment, we mult be furprifed to find that the pre¬ eminence mult clearly be given to the Celtic bard. This appears nowhere more remarkable than in the fenti- ments which he exprelfes towards his enemies. “ U- <£ thal fell beneath my fword, and the fons of Berra- “ thon fled.—It was then I law him in his beauty, “ and the tear hung in my eye. Thou art fallen, young “ tree, I'faid, with all thy beauty round thee. Thou “ art fallen on thy plains, and the field is bare. The “ winds come from the defart, and there is no found “ in thy leaves! Lovely art thou in death, fon of car- “ borne Larthmore *!” His fuppofition, that all the little feuds and differences of this life fhouid be forgot in a future ftate, and that thofe who had onee been foes would “ llretch their arms to the fame (hell in “ Loda,” gives us the higheft idea of the man as well as of the poet. “ Daughter of beauty, thou art low! “ A flrange fhore receives thy corfe. But the ghofls “ of Morven will open their halls, when they fee thee “ coming. Heroes around the feaft of dim (hells, in “ the midfl of clouds, fhall admire thee; and virgins - “ fhall touch the harp of miftf.” “ The feuds of “ other years by the mighty dead are forgotten. The “ warriors now meet in peace, and ride together on “ the tempefl’s wing. No clang of the fhield, no noife V of the fpear, is heard in their peaceful dwellings. “ Side by fide they fit, who once mixed in battle their “ fteel. There, Lochlin and Morven meet at the mu- f‘ tual feaft, and liften together to the fong of their “ bards J.” But the fublimity of moral fentiments, if they want¬ ed the foftening of the tender, would be in hazard of giving a ftiff air to poetry. It is not enough that we admire. Admiration is a cold feeling in comparifon of that deep intereft the heart takes in tender and pa¬ thetic fcenes. With fcenes of this kind Offian abounds; and his high merit in thefe is inconteftable. He may be blamed for drawing tears too often from our eyes; but that he has the power of commanding them, no man who has the leaft fenfibility can queftioh. His poems awake the tendered fympathies, and infpirethe molt generous emotions. No reader can rife from him without being warmed with the fentiments of humani¬ ty, virtue, and honour. But the excellency of thefe poems occafioned in many perfons a doubt of their authenticity. Their genuinenefs, however, has been very ably defended by Dr Blair and Lord Karnes, and warmly fupported by the author of the Ga/ic Antiquities, who has given the public fome more remains of Offian’s poetry. As the nature of our work will not allow us to treat this matter at full length, we fhall only give a brief view of the arguments offered in fupport of the authenticity of thefe poems, referring our readers to the authors juft now mentioned for fuller fatisfadion. Thefe compofitions, fay they, have all the internal marks of antiquity fo ftrongly imprefled. upon them, that no reader of tafte and judgment can deny their claim to it. They exhibit fo lively a pi&ure of cuftoms which have difappeared for ages, as could be drawn only from nature and real life. The features are fo diftinft, that few portraits of the life continual¬ ly palling before us are found to be drawn with fo much likenefs. The; manners uniformly relate to a very early ftage of fociety ; and no hint, no allufion to the arts, cuftoms, or manners, of a more advanced period, appears throughout the poems. To that di- ftin&ion of ranks, which is always found in adult fo- cieties, the poet appears to have been a perfedl ftranger. The firft heroes prepare their own repafts, and indifcriminately condefcend to the moft menial fervices. Their quarrels-arife from caufes generally flight, but in fuch a period extremely natural. A ri- valfhip in love, an omiffion at a feaft, or an affront at a tournament, are often the foundation of a quarrel among Angle heroes. And the wars in which whole tribes are engaged, are carried on with a view, not to enlarge their territory, but to revenge perhaps the kill¬ ing of a few deer on their mountains, or the taking forcibly away one of their women. Their occupation was war and hunting, and their chief ambition was to have their fame in the fongs of the bards. The notions of a future ftate, exhibited in thefe poems, are likewife ftrongly marked with the charac¬ ters of antiquity. A creed fo uncommon that the ima¬ gination of a modern could not be fuppofed to grafp fo ftrong an idea of it from mere fancy, is uniformly fupported throughout. This creed is extremely fimple, but admirably fuited to the times. The language too, and the ftrmSure, of thefe poems, bear the moft ftriking chara&ers of antiquity. The language is bold, animated, and metaphorical, fucli as it is found to be in all infant-ftates; where the words, as well as the ideas and objefts, muft be few ; and where the language, like the imagination, is ftrong and undifciplined. No ahftraft, and few general, terms appear in the poems of Offian. If objedfs are but in¬ troduced in a fimile, they are always particularized. It is “ the young pine of Inifhuna it is “ the bow of the fhowery Lena.” This charadter, fo confpicuou» in the poems of Offian, is a linking feature in the lan¬ guage of all early ftates; whofe objedls and ideas are few and particular, and whofe ordinary converfation is of courfe highly figurative and poetical. A pidhire, there¬ fore, marked with fuch ftriking features, could not be drawn without an original. The whole texture of the compofition is alfo, like the language, bold, nervous, and concife ; yet always plain and artlefs; without any thing of that modern refinement, or elaborate decoration, which attend the advancement ofliterature. No foreign ornaments are hunted after. The wild and grand nature which lay within the poet’s view, is the only fource from which he draws his ornaments. Beycnd this circle, his ima¬ gination, though quick and rapid, feldom made any excurfion. We perceive his language always to be that of a perfon who faw and felt what he deferibes; who bore a part in the expeditions which he cele¬ brates, and who fought in the battles which he fings. In giving the external and more pofitive proofs of the authenticity of Offian’s poems, it is obferved,—That there have been in the Highlands of Scotland, for fome ages back, a vaft many poems aferibed to Offian : That thefe poems have been held in the higheft vene¬ ration, repeated by almoft all perfons, and on all oc- caiions. Thefe are fads fo well known, that no¬ body as yet has been hardy enough to deny them; There is pot an old man in the Highlands, who will 32 O 2 not OSS [ 577^ T oss Ofinn. not declare, that be heard fuch poems repeated by his cultivated with moil fuccefs in the earlieft Rages of (b- ~ father and grandfather, as pieces of the moft remote antiquity, There is not a diftridt in the Highlands where there are not many places, waters, ifles, caves, and mountains, which, from time immemorial, are called after the names of Offian’s heroes.—There is not a lover of ancient tale or poetry, however illiterate, who is not well acquainted with almoft every fingle tiame, charadter, and incident, mentioned in thofe tranf- lations of Offian’s poems, which he may have never heard of.-—Bards, who are themfelves feveral centut its old, quote thofe poems, imitate them, and refer to ciety ; that in Greece, Orpheus, Linus, Hefiod, and” Homer, wrote their admirable poems fome ages belore any thing had been written in profe in the Greek lan¬ guage ; that the book of Job, written in a very early period of fociety, is highly poetical; that among the tribes of Lapland and America, there have been found, in the earlieft Rate, fome excellent pieces of poetry. That the Caledonians in particular, had fome peculiar inftitutions, which tended to improve their poetry : their druids were among the moft learned phiiofophers which perhaps any age or country produced; their them.—The ordinary converfation and comparifons of bards or poets were the difciples of thofe druids, and the Highlanders frequently allude to the cuftoms and characters mentioned in them;—and many of their moft common proverbs, eltablifhed by the moft ancient * See ex- ofe, are lines borrowed from the poems of Gffian amples un- ’p^e moft ancient of the clans boaft of deriving their thdTheads Pe^'gree5 eac^ from one of Offian’s heroes;—and in the Galicm*nY l^e %ns armorial affumed by them, are drawn jintiquities, from the feats afcribed to their predeceflbrs in thofe were always a (landing order, to which none but the moft promifmg genittfes were admitted.

From fuch a people, the fuperinr merit of OITian’s poems would naturally procure every encouragement, which they always retained as long as the manners of the people remained unchanged. Many other reafons confpired to preferve the poems of Ofiian. The martial and intrepid fpirit which they breathed, made it the imereti of the chieftains to pre¬ ferve them : the drain of juftice, generofity, and hu¬ manity, which runs through them, recommended them to the fuperintendants of religion, who well knew how much the morals of a people muft be tin&ured with thofe fongs which they are continually repeating, and which have all the advantages of poetry and of mufic. In fuperditious ages, the people revered thefe poems from their being addrefled generally to fome “ fon of “ the rock,” fuppofed to be the tutelar faint of the place, or the great Iriih apoftle St Patrick. Befides, every hill and dale which the natives of the Highlands walked over, was claffic ground. Every mountain, rock, and river, was immortalized in the fong. This fong would naturally be fuggelled by the light of thefe obje&s, and every body would hum it as he walked along. All the proverbs and cuftoms to which thefe poems gave rife, would operate in the fame manner. The fon would alk what they meant, and the father would repeat the fong from which they were taken. The diftinft and unfubdued ftate in which the High¬ landers remained for fo long a courfe of ages, every clan, one generation after another, inhabiting the fame valley, till towards the prefent century, contributed much to preferve their traditions and their poems ; and the conftant and general cuftom of repeating thefe in the winter-nights, kept them always alive in their remembrance. To thefe caufes and cuftoms the prefervation of Offian’s poems, for fo many ages, has been aferibed. But thefe caufes and cuftoms have ceafed to exift; and the poems of Ollian, of courfe, have ceafed to be repeated.—Within a century back, the Highlands of Scotland have undergone a greater revolution than it had done for ten before that period. With a quicker pace the feudal fyftem vanifhed ; property fluctuated ; new laws and new cuftoms ftept in, and fupplanted the old: and all this, with fuch hidden and fuch violent convulfions, as may well account for the (baking of a fabric which had ftood fo many ages, that it feemed to have bidden defiance to all the injuries of time. Even fince Mr Macpherfon gathered the poe* s in his collection, the amufements, employments, and tafte of the Highlanders are much altered. A greater attention to commerce, agriculture, and pafturage, has quite engrofled that partial attention which was paid, even then, to the fong of the bard. In twenty years hence, if manners continue to change £b fall as they do at prefent, the fainted traces will fcarce be found of thCfe tales and poems. “ Oflian himfelf is the laft “ of his race ; and he too (hall foon be no more, for “ his grey branches are already ftrewed on all the “ winds.” Among the caufes which make thefe poems vaniih fo rapidly, poverty and the iron rod (hould come in for a large (hare. From the baneful (hade of thofe imtrdeters of the mufe, the light of the fong muft faft retire. No other reafon needs be given why the pre¬ fent Highlanders neglect fo much ihe fongs of their 71 ] o s T fathers.—Once, the humble, but happy vafifal, fat at Oflnm his cafe, at the foot of his grey rock or green tree, ] Few were his wants, and fewer ftill his carts ; for he _ .

It is more agreeable to remark, as another caufe for the neglect of ancient poems and traditions, the growth of induftry, which fills up all the blanks of time to more advantage, and efpecially the increafe of more ufeful knowledge.—But above all, the ex¬ tinction of the order of the bards haftened the cata- ftrophe of Oflian’s poems. By a happy concidence Macpherfon overtook the very laft that remained of this order, (Macvurich, bard to Clanronald), and got his treafure. This faCt (with the red book furniihed by Mr Macdonald of Croidart,and fome other MSS.) ac¬ counts for MrMacpherfon’s having found thefe poems in greater number and perfection than they could ever fince be met with. The fragments, however, which have fince been gathered, give a credibility to every thing that has been faid of the original grandeur of the building. After giving this abftraCt of the arguments urged for the authenticity of Oflian’s poems, and of the anfwers to objections darted againft them, we (hall Conclude with referring thofe who wi(h to fee the fubjeCt difeufled on a different footing, namely, by an appeal to fa£lst to two pamphlets recently publiftied, Shanu's Inquiry, and Clark's Anfuer: From the former of which, the authenticity of Offian’s poems feemed to fullain a very formidable attack ; till the latter appeared, expofed the impotence of the attempt, and (hewed the unfliaken bails on which the objeCt of it refted. So that now we feem authorifed to conclude, without the imputation of partiality, that the contro- verfy is at laft come to an end; and that the genuine- nefs of the poems will be as univerfally eftabliftied in other nations, as the originals have been admired for ages in the Highlands.

OSTRACISM, in Grecian antiquity, denotes the banifhment of luch perfons whofe merit and influence gave umbrage to the people of Athens, left they fhould atternpt any thing againft the public liberty. This punifhment was called oftracifm, from the Greek word os-fKxovj which properly fignifies a “ (hell;” but when applied to this objed, it is ufed for the billet on which the Athenians wrote the names of the citizens whom they intended to banifh. The learned are divided with regard to the fubftance of which this billet was form¬ ed: fome infift that it was a fmall (tone, or a piece of brick; fome, that it was a piece of bark ; and others affert, that it was a fhell. The word admits moft of thefe interpretations. But what determines .its true fenfe, is the epithet given it by ancient authors, of ceramice maflix; which words fignify, “ The punifli- ment of potter’s clay:” and this expreffion feems to us a proof, that the word orp«r.ov} when applied on this occaiion, fignifies a “ piece of baked earth, in the form of a (hell;” and undoubtedly the Latin authors had this idea of the word here, for they tranflated it by tefu/a. The ancients are likewife divided with regard to the time when oftracifm was inftituted. But they all agree, that the perfon who moved the law, was its fiiu vic¬ tim. But as to the name of its patron, and the time of its eftabliftiment, they differ extremely. Many are of opinion, that oftracifm owes its origin to very re¬ mote times. However that be, the puniftiment of oftracifm was infli&ed by the Athenians when their liberty was ia danger. If, for inftance, jealoufy or ambition had fowed difeord among the chiefs of the republic; and if different parties were formed, which threatened fome revolution O S T [ 5773 ] O S T ©ftraeifm. revolution in the ftate; the people aflembled to propofe - "-»■ meafures proper to be taken in order to prevent the confequences of a divifion which in the end might be fatal to freedom. Oftracifm was the remedy to which they ufually had recourfe on thefe occafions; and the confultations of the people generally terminated with a decree, in which a day was fixed for a particular af- fembly, when they were to proceed to the fentence of oftracifm. Then they who were threatened with ba- niihment, omitted no afliduity or art which might gain them the favour of the people. They made ha¬ rangues to evince their innocence, and the great inju- ftice that would be done them if they were banifhed. They folicited, in perfon, the intereft of every citizen; all their party exerted themfelves in their behalf; they procured informers to vilify the chiefs of the oppofite faftion. Some time before the meeting of the affem- bly, a wooden inclofure was raifed in the forum, with ten doors, /. e. with as many as there were tribes in the republic; and when the appointed day was come, the citizens of each tribe entered at their refpe&ive door, and threw into the middle of the inclofure the fmall brick on which the citizen’s name was written whofe banilhment they voted. The archons and the ,fenate prefided at this affembly, and counted the bil¬ lets. He who was condemned by 6000 of his fellow- citizens, was obliged to quit the city within ten days; for 6000 voices, at leaft, were requifite to banifh an Athenian by oftracifm. The Athenians, without doubt, forefaw the incon¬ veniences to which this law was fubjedt ; but they chofe rather, as Cornelius Neposhath remarked, fome- times to expofe the innocent to an unjuft cenfure, than to live in continual alarms. Yet as they were fenfible that the injufticeof confounding virtue and vice would have been too flagrant, they foftened, as much' as they could, the rigour of oftracifm. It was not ag¬ gravated with the circurriftances which were matt dif- bonourable and fhocking in the ordinary mode of exile. They did not confifcate the goods of thofe who were baniihed by oftracifm. They enjoyed the produce of their effedis in the places into which they were banifhed ; and they were banifhed only for a certain time. But in the common banifhment,"the goods of the exiles were always confifcated, and no hopes were given them of ever returning to Athens. The fcholiaft of Ariftopbanes informs us of a third difference betwixt oftracifm and the common banifh¬ ment. He fays, that a particular place of retirement was affigned to thofe who were banifhed by oftracifm, which was not appointed to the other exiles. Wc fuf- pedl, however, the truth of this obfervation; forThe- miftocles was certainly not limited in his banifliment. That great man, as we are told by Thucydides, tho’ his chief refidence. was at Argi, travelled over all the Pdoponnefus. This punifhment, far from conveying the idea of infamy, became, at Athens, -a proof of merit, by the objedls on which it was inflidled ; as Ariftides the fo- phift juftly obferves, in his fecond declamation againft the Gorgias of Plato, where he fays, that oftracifm was not an eflfedt of the vindidlive fpirit of the people againft thofe whom it condemned ; that the law, whe¬ ther good or bad (for he enters not into an examina¬ tion of the queftion), was only meant to prune the luxuriant growth of tranfcendent merit; that it con- Oftracifm demned to an exile of ten years, only thofe illuftrious (I men who were accufed of being exalted far above oflrea' other citizens by their confpicuous virtue; and that none of that public indignation was fhewn to the exiles by oftracifm, which commonly breaks out againft cri¬ minals. Such were the mitigations with which this law was introduced among the Athenians: and by them we fee that they were fenfible of all the inconveniences to which it was fubjeft. They were indeed too enlight¬ ened a people, not to forefee the many inftancesof in- juftice which it might produce ; that if in fome re- fpefts it would be favourable to liberty, in others it would be its enemy, by condemning citizens without allowing them a previous defence, and by making a capricious and envious people arbiters of the fate of great men ; that it might even become pernicious to the ftate, by depriving it of its heft fubjefts, and by rendering the adminiftration of public affairs an odious employment to men of capital talents and virtue. However great the inconveniences of Oftracifm were, it would not have been impofiible to avoid them; and we may add, that this law would have been of fervice to the ftate, if the people by whoba it was in- ftituted had always had difcernment enough only to give it force on fuch occafions as endangered liberty. But its fate was like that of almoft all other laws which the wifeft legiflators have planned for the good of com¬ munities. Deftined by their inftitution to maintain order, to reprefs injuftice, and to protect innocence, men have found ways to pervert their application, and have made them inftruments to gratify their private paffions. Thus oftraciftn was eftablilhed to prevent the dangerous enterprifes of the great, and to preferve the vigour of the democracy; but the people of A- thens, naturally jealous and envious, exerted that law, to remove men of eminent merit from the Jlate, by whofe prefence they were reproved and intimidated. The fear of tyranny was commonly but a fpecious pretext with which they veiled their malignity. The repeated vi&ories which they had gained over the Per- fians, had rendered them, fays Plutarch, proud and infolent. Intoxicated with their profperity, they arro¬ gated all its glory to themfelves ; they were jealous of thofe citizens, whofe political and military talents were the fubjefts of public culogium. They thought the glory acquired by great men diminiihed the'ir own re¬ putation. An Athenian no fooner diftinguilhed himfelf by a fplendid aftion, than he was marked out as a vic¬ tim by public envy. His reputation was a fufficient - reafon for his banilhment. OSTRACITES, in natural hiftory, the name which authors have given the fofiile oyiter-ftiell.

Britain has been noted for oyftcrs from the time of ” Juvenal, who, fatyrizing an epicure, fays, Circxh nataforent, an Lucrimm ad Saxum, Rutupinove edita fundo, OJirea, callebat primo dcprendere morfu. He, whether Circe’s rock his oyflers bore, Or Lucrine iake, or diftant Richborough’s Hi ore Knew at fir(l tafle. The luxurious Romans were very fond of this fifh, and had their layers or ftews for oytlefs as we have at prefent. Sergius Grata was the firft inventor, 38 early as t^ie t'mek* Craffus the orator. He did vol. iv.M ' not ma^e them for the fake of indulging his appetite, p. ioi. but thro’avarice, and made great profits from them. Grata got great credit for his Lucrine oyfters ; for, fays Pliny, the Britifli were not then known. The ancients eat them raw, and fometimes roaft- ed. They had alfo a cuftom of ftewing them with mallows and docks, or with fifh, and efieemed them very nouri filing. Britain ftill keeps its fuperiority in oyfters over other countries. Moft of our coafts produce them naturally ; and in fuch places they are taken by dred¬ ging, and are become an article of commerce, both raw and pickled. The very (hells, calcined, become an ufeful medicine as an abforbent. In common with other (hells, they prove an excellent manure. Stews or layers of oyfters are formed in places which nature never allotted as habitations for them. Thofe near Colchefter have been long famous ; at pre¬ fent there are others that at lead rival the former, near the mouth of the Thames. The oyfters, or their fpats, are brought to convenient places, where they improve in ;a!te and (ize. It is an error to fuppofe, that the fine green obferved in oyfters taken from artificial beds, is owing to copperas; it being notorious how deftruc- tive the fubftance or the folution of it is to all fifh. We cannot give a better account of the caufe, or of the whole treament of oyfters, than what is preferved in the learned bifhop Sprat’s hiftory of the Royal Socie¬ ty, from p. 307, to 309. “ In the month of May, the oyfters caft their fpawn, (which the dredgers call their it is like to a drop of candle, and about the bignefs of a half¬ penny. “ The fpat cleaves to ftones, old oyfter-fhells, pieces of wood, and fuch like things, at the bottom of the fea, which they call cultch* “ It is probably conje&ured, that the fpat in 24 hours begins to have a (hell. “ In the month of May, the dredgers (by the law of the admiralty court) have liberty to catch all man¬ ner of oyfters, of what fize foever. “ When they have taken them, with a knife they gently raife the fmall brood from the cultch, and then they throw the cultch in again, to preferve the ground -for the future, unlefs they be fo newly fpat, that they cannot be fafely fevered from the cultch ; in that cafe they are permitted to take the (tone or (hell, &c. that the fpat is upon, one (hell having many times 20 fpats. “ After the month of May, it is felony to carry away the cultch, and punilhable to take any other oyfters, unlefs it be thofe of fize, (that is to fay) about the bignefs of an half-crown piece, or when, the two Oftrea (hells being (hut, a fair (hilling will rattle between Oftrieh. ^ them. “ The places where tbefe oyfters are chiefly catched, are called the Pent-Burnham, Malden, and Colne-wa¬ ters ; the latter taking its name from the river of Colne, which pafleth by Colne-Chefter, gives the name to that town, and runs into a cresk of the fea, at a place called the Hythe, being the fuburbs of the town. “ This brood and other oyfters, they carry to the creeks of the fea, at Brickel-Sea, Merfy, Langno, Fingrego, Wivenho, Tolelbury, and Saltcoafe, and there throw them into the channel, which they call their beds or layers, where they grow and fatten, and in two or three years the fmalleft brood will be oyfters of the fize aforefaid. “ Thofe oyfters which they would have green, they put into pits about three feet deep in the falt-marihes, which are overflowed only at fpring-tides, to which they havefluices, and let out the falt-water until it is about a foot and half deep. “ Thefe pits, from fome quality in the foil co-ope¬ rating with the heat of the fun, will become green, and communicate their colour to the oyfters that are put into them in four or five days, tho’ they common¬ ly let them continue there fix weeks or two months, in which time they will be of a dark green. “ To prove that the fun operates in the greening, Tolefbury pits will green only in fummer; but that the earth hath the greater power, Brickel-Sea pits green both winter and fummer : and for a further proof, a pit within a foot of a greening-pit will not green; and thofe that did green very well, will in time lofe their quality. “ The oyfters, when the tide comes in, lie with their hollow (hell downwards; and when it goes out, they turn on the other fide: they remove not from their place, unlefs in cold weather, to cover themfelves in the oufe. “ The reafon of the fcarcity of oyfters, and confe- quently of their dearnefs, is, becaufe. they are of late years bought up by the Dutch. “ There are great penalties by the admiralty court, laid upon thofe that fifti out of thofe grounds which the court appoints, or that deftroy the cultcb, or that take any oyfters that are not of fize, or that do not tread under their feet, or throw upon the (hore, a fifh which they call a five finger, refembling a fpur-rowel, becaufe that fifh gets into the oyfters when they gape, and fucks them out. “ The reafon that fuch a penalty is fet upon any that (hall deftroy the cultch, is, becaufe they find that if that be taken away, the oufe will increafe, and the mufcles and cockles will breed there, and de¬ ftroy the oyfters, they having not whereon to (tick their fpat. “ The oyfters are fick after they have fpat; but in June and July they begin to mend, and in Augult they are perfe&ly well: the male oyfter is black-fick, having a black fubftance in the fin ; the female white- fick (as they term it), having a milky fubftance in the fin.

The tfy* coaft. viewed from the fea, prefents a moft beautiful profpeft, being elevated like an amphitheatre. The ifland is Ikirted with a reef of rocks, and towards the fea is level, being covered with fruit-trees of various kinds, particularly the cocoa-nut. At the diftance of about three miles from the ftiore, the country rifes in¬ to lofty hills that are covered with wood, and termi¬ nate in peaks, from which large rivers are precipitated into the fea. The ftones every where appear to have been burnt, not one being found which did not give manifeft figns of fire ; fo that there is great reafon for fuppofing, that this and the neighbouring iflands are either the (battered remains of a continent, or were torn from rocks, which from the creation of the world have been the bed of the fea, and thrown up in heaps to a height which the waters never reach. What is further extraordinary, the water does not gradually grow (hallow as we approach the (hore, but is of im- menfe depth clofe by the land ; and the iflands in this neighbourhood are almoft every where furrounded by reefs, which appear to be rude and broken in the manner that fome violent concuifion would naturally leave the folid fubftance of the earth ; and Mr Forfter faw a rock with projecting longitudinal angles of black compaft bafaltes. The exterior ranges of hills are fometimes entirely barren, and contain a great quan¬ tity of yellowiflr clay, mixed with iron ochre; but others are covered with mould and wood like the moun¬ tains in the internal parts of the country. Pieces of quartz are fometimes met with here ; but no indica¬ tions of precious minerals or metals of any kind have *, been obferved, iron only excepted. Climate. The air is extremely healthy and pleafant; the heat is not troublefome; and frefli meat will keep very well for two days, and fi(h one day. The winds do not blow conftantly from the eaft, but generally a little breeze from eaft to fouth-fouth eaft. The tide rifes Vox.. VIII. very little ; dnd, being governed by the winds, is very Otahekec* uncertain. “ The climate,” fays Mr Bougainville, “ is fo healthy, that notwithftanding the hard labour of the (hips companies while on (bore, though the men were continually in the water, and expofed to the meridian fun, though they dept upon the bare foil, and in'the open air, none of them fell fick ; thofe who were af¬ flicted with the fcurvy, and were fent on (bore, regain¬ ed their ftrength : although they were obliged to affift in the ereCting of a fort, and had fcarce one uninter¬ rupted night, yet they were fo far recovered in the (hort fpace of time they continued there, that they were afterwards perfectly cured on board.” 3 Notwithftanding the great height of the inland Highmoun- mountains of Otaheitee, none of their rocks have thetains* appearance of barrennefs, every one of them being co¬ vered with woods. “ We hardly believed our eyes,” fays M. de Bougainville, “ when we faw a peak cover¬ ed with woods up to its higheft fummit, which rifes above the level of the mountains in the anterior parts of the fouthern quarter of this ifland. Its apparent fize feemed to be more than 30 toifes in diameter, and grew lefs in breadth as it rofe higher. At a diftance it might have been taken for a pyramid of immenfe height, which the hand of an able fculptor had adorn¬ ed with garlands and foliage.” One of the mates of the dolphin, with a party of marines and feamen, pe¬ netrated into the interior parts of the ifland; and ha¬ ving alcended, with great difficulty, a mountain which they fuppofed to be a mile high, they difcovered mountains before them fo much higher, that with re- fped to them they feemed to be in a valley: towards the fea the view was enchanting, the fides of the hills were beautifully clothed with wood, villages were every where interfperfed, and the valleys between them afforded a ftill richer profpeft; the houfes flood thicker, and the verdure was more luxuriant; and Mr Forfter, with other gentlemen, afeended to the fummit of one of the higheft mountains in the ifland, from whence they had a profpeCt of the ifland of Huahine, and fome others lying at the dittance of 40 leagues; from which we may form fome judgment of the prodigious height of that mountain. The view of the fertile plain below them, and of a river making innumerable me¬ anders, was delightful in the higheft degree. The ve¬ getation on the upper part of the mountains was luxu¬ riant, and the woods confided of many unknown forts of trees and plants. 4 The foil of this ifland is a rich fat earth, of a black-Soil and ifh colour. It produces fpontaneoufly, or with thePro^uce* flighteft culture imaginable, a great variety of the moft excellent fruits; fuch as bread-fruit, cocoa nuts, bananas of 13 forts, plantains, potatoes, yams, a fruit known here by the name ai jambu, and reckoned moft delicious; fugar-canes, which the inhabitants eat raw } ginger ; turmeric ; a root of the falep kind, called by the inhabitants pea ; a plant called etbee, of which the root only is eaten; a fruit that grows in a pod like that of a large kidney-bean, by the natives called a tree called its found is loft; as in the words pfalms, pfychology, pto- Icmaic, ptifan, &c.

PABULUM, among natural philofophers, the fame with Fuel. PACE, a meafure taken from the fpace between the two feet of a man in walking ; ufually reckoned two feet and a half, and in fome men a yard or three feet. The geometrical pace is five feet; and 60,000 fuch paces make one degree on the equator. Pace, in the manege, is of three kinds, viz. walk, trot, and gallop ; to which may be added an amble, becaufe fome horfes have it naturally. Hoffes which go fhuffling, or with mixed paces be¬ tween the walk and amble, are for the mod part of no value ; which commonly proceeds from their fiery tem¬ per, but fometimes from a weaknefs in their reins or kgs. Pace (Richard), a learned Englifhman, born about the year 1482. He was educated at the charge of Thomas Langton bifttop of Winchefter, whom he ferved as an amanuenfis, and afterwards entered into the fervice of cardinal Bainbridge. His accomplifh- ments rendered him fo acceptable to Henry VIII. that he made him fecretary of ftate; and, entering into or¬ ders, he was admitted prebendary in the church of York, archdeacon of Dorfet, and dean of St Paul’s, &c. which preferments were conferred on him during his abfence on foreign embaflies. In 1524, he was lent to Rome on the death of pope Leo X. to folicit the papal chair for cardinal Wolfey; but a new Pope was eledted before his arrival, a circumftance that pro¬ ved the epocha of his troubles. He fell under the dif- pleafure of the difappointed cardinal; and being foon after employed as ambaffador at Venice, he was fo ne- glefted and hardly ufed, that he was feized with a phrenzy: Upon which the king ordered him home; Pachamac and being carefully attended by the phyficians at the 'l king’s command, he was in a ftiort time rettored to the Packa&ft ufe of his reafon, and then applied himfelf to the ftu- dy of the Hebrew tongue. Being now introduced to his Majefty, he remonftrated againft the Cardinal’s cruelty: who being ordered to clear himfelf, fummon- ed Pace before him, fitting in judgment with the duke of Norfolk and others; who condemned Pace, and fent him to the Tower ; where he remained two years, till he was discharged by the king’s command.—When he was enlarged, he refigned his deaneries, and died iti retirement at Stepney in 1532; after having wrote fe- veral works, and enjoyed the tfteem of the learned among his cotemporaries ; efpecially of Sir Thomas More, and Erafmus. PACHAMAC, a valley of Peru, in South Ame¬ rica, ten miles fouth of Lima ; celebrated for its plea- fantnefs and fertility, but more on account of a mag¬ nificent temple built by the Incas of Peru, to the ho¬ nour of their god. When the Spaniards conquered Peru, they found immenfe riches therein. PACHODECARHOMBIS, in natural hiftory, the name of a genus of fofiils, of the clafs of falemi~ tee, exprefling a thick rhomboidal body compofed of ten planes. PACHSU, a fmall ifland in the Mediterranean fea, near the coaft of Epirus, and in European Turky. It lies fouth of Corfu, and is fubjeft to Venice. PACIFIC ocean, that vaft ocean which feparates Afia from America. It is called Pacific, from the mo¬ derate weather the firft mariners who failed in it met with between the tropics: and it was called South Sea, becaufe the Spaniards crofled the ifthmus of Darien from north to fouth, when they firft difeovered it; tho* it is properly the Weftern ocean, with regard to Ame¬ rica. PACK, in commerce, denotes a quantity of goods, made up in loads, or bales, for carriage. A pack of wool is 17 ftone and 2 pounds, or a horfe’s load. PACKET, or Packet .5^/, a veflel appointed by the government to carry the mail of letters, packets, and exprefles, from one kingdom to another by fea, in the moft expeditious manner. Thus, the packet- boats, under the direction of the poft-mafter-general of Great Britain, carry the mails from Dover to Ca¬ lais, from Falmouth to Lifbon, from Harwich toHel- voetfluys, and from Parkgate to Dublin. PACTOLUS (anc. geog.), a river of Lydia, call¬ ed Chryforrhoas, from its rolling down golden fand, according to Herodotus, Plutarch, Pliny, and Stra¬ bo ; rifing in mount Tmolus, (Strabo). From this river Croefus is thought to have had all his riches. In Strabo’s time it ceafed to roll down any. It ran thro’ Sardes ; after which it fell into the Hermus, and both together into the Aegean Sea at Phocaea in Ionia. A river celebrated by Virgil, Ovid, Lucan, Ly'cophron, Horace, Apollonius. PACKAGE, is a fmall duty of one penny in the pound. PAD ppacos pound, paid for all goods not particularly rated. !1 PACOS, in zoology. See Camelus. Padefborn- PACUV1US (Marcus), of Brundufiucn in Gala- bria, a tragic poet in high reputation about the year of Rome 600. He was nephew of Ennius; publifh d feveral theatrical pieces, tho’ we have only fome frag¬ ments of his poetry remaining ; and died at Tarentum at above 90 years of age. PA DAN ARAM (Bible), literally the plains of Aram, or Syria; tranflated by the Seventy, Amply Mefopotamia, or Mofopotamia, of Syria ; by the Vul¬ gate, Syrian; the .Syrians on this and on the other fide of the Euphrates, not differing remarkably from each other in language and manners, as Jofephus al¬ lows. PADDOC, or Paddoc-Ccar/e, a piece of ground encompaffed with pales or a wall, and taken out of a park for exhibiting races with gre-hounds, for plates, wagers, or the like. A paddoc is generally a mile long, and a quarter of a mile broad : at the one end is a little houfe where the dogs are to be entered, and whence they are flip¬ ped ; near which are pens to inclofe two or three deer for the fport. Along the courfe are feveral pofts, viz. the low poft, which is 160 yards from the dog-houfe and pens; the quarter of a mile poft, half-mile poft, and pinching poft ; befides the ditch, which is a place made to receive the deer, and preferve them from far¬ ther purfuit. And near this place are feats for the judges chofen to decide the wager. The keepers, in order to flip the dogs fairly, put a falling collar upon each, flipped round a ring; and the deer being turned loofe, and put forward by a teazer, as foon as he is arrived at the low-poft, the dog-houfe door is thrown open, and the dogs flipped. If now the deer fwerve fo much, as that his head is judged nearer the dog-houfe than the ditch before he arrive at the pinching-poft, it is no match, and muft be run over again three days after: but if the deer runs ftraight beyond the pinchipg-poft, then that dog which is ntareft when he fwerves, or is blanched by any acci¬ dent, wins the match ; but if no fuch fwerve hap¬ pens, then the match is won by the dog who firft leaps the ditch. PADERBORN, a duchy of Germany in the circle of Weftphalja, has the county of JLippe on the north and weft; Heffe-CafTel and Waldeck, on the fouth ; and Munfter, with the duchy of Weftphalia, on the weft. Its greateft length from eaft to weft is about 40 miles, and its breadth where wideft 30. Some parts of it yield good pasture, and breed abundance of -cattle ; but it is not very fruitful in corn. There is a heath called the Senne or Ser.de, of great extent, but very barren and dcfolate. There are, however, good iron mines in the country, with fait and medicinal fprings, plenty of deer and other game; and it is watered with feveral rivers abounding with ftfh, as the Wcfcr, the Dimer, the Bcvcr, the Nette, the great Emmer, the Lippe, the Alme, and the Padtr. It contains 54 parifhes, in which are 25 market-towns, and 16 monasteries. The Roman Catholic is the pre¬ dominant religion of the country,- yet there are alfo many Proteftants in it. The bifhopric was erefted by Charlemagne, towards the clofe of the eighth century ; ^nd the cathedral was confeerated by pope Leo in PAD perfon, anno 796. The bifhop is fovereign of the PaderbonW country, a prince of the empire, and fuffragan of the Pa^ua‘ \ archbifhop of Mentz. His revenue is about 30,000 pounds a year, and he is able to raife 3000 men. In the matricula, his affefTment is 18 horfe and 34 foot, or 352 florins monthly in lieu of them. Towards the charges of the fovereign courts of the empire, he payg for each term, 162 rix-dollars and 29 krnitzers. Ttie chapter conflfts of 24 capitular canons, who muft prove their noble extra&ion by four defeents. The arms of the bilhopric are a crofs or, in a field gules. For the government of it, and the adminiftration of juftice, there are feveral councils and colleges under the bi¬ fhop. Here are alfo a hereditary marfhal, fewer, cup¬ bearer, chamberlain, fteward, and purveyor. It was in this bifhopric that Qujntilius Varus, with the Ro¬ man army under his command, was routed by the Germans under Arminius. Padderborn, the capital of the above bifhop¬ ric. It ftands 40 miles north-weft of Cafftl, 50 fouth-eaft of Munfter, and 60 fouth-weft of Hano¬ ver; being a large, populous, well built, and well fortified city. Its name is compounded of pader, a ri¬ vulet, which rifes juft under the high altar of the ca¬ thedral, and horn, i. e. a fpring. It was one of the Hanfe-tovvns ; and, till 1604, an imperial city. The cathedral is a grand fabric, inferior to few in the em¬ pire. There fs a gold crucifix in it of 60 pounds weight, prefented by Otho II. The umverfity, of which the Jcfuits have the direftion, was founded in 1592, and the walls were built in the beginning of the 1 uh century. In 1530, an attempt was made to in¬ troduce Lutheranifm ; but 16 of the principal citizens who had embraced it were executed, and the reft; ob¬ liged to abjure it. Duke Chriftian of Brunfwic car¬ ried off.from hence, in 1692, the filver images of the 12 apoftles, and the filver coffin of St Lotharius; and had them coined into money, with this infeription, God's Friend, the Priejis Enemy. The trade of this town, though formerly great, is now incopfiderable ; and the inhabitants fubfift moftly by agriculture, and breeding of cattle. Though the bifhop has a palace in the city, he refides (when he vouchfafes to vifit this country, which is feldom, having other and more va¬ luable benefices) at Neuhaus, feven miles off, where he has a magnificent caftle.. Charlemagne, and other emperors, fometimes refided here, and held diets of the empire. PADUA, an ancient, large, and celebrated city of Italy, with an univerfity and a bilhop’s fee. It is alfo capital of the Paduano; but is much lefs confiderable than it was formerly : for it now contains no more than 30,000 inhabitants, whereas it formerly had 100,000, and many of the houfes are gone to ruin : however, the hall where juftjee is adminiftered, is a t’uperb ftruc- ture. Tne cathedra! church, and the college of the univerfity, are in that part called the Old Town ; and there are piazzas under all the houfes, -where perfons may Walk w ithout being expofed to the weather. The garden of the univerfity is curious, on account of the number of plants. Here a ftudent may take his de¬ grees, let him be of what fe& of Chriliianity he will ; nay, though he (hould be a Jew or a Turk. The pa¬ tron of this city is St Anthony, who lies in the ca¬ thedral ; they have fuch a veneration for him, that the [ 5796 ] P iE O [ 5797 ] PAG ‘adiuno beggars do not aflc charity in the name of God, but l| , for the love of St Anthony. The Jews live in a di- ?goma. part 0f city; and the neighbouring moun¬ tains produce excellent wine and oil, with delicious fruit. It was taken by the Venetians in 1706. It is feated on the rivers Brentac and Bachiglione, in a fine plain ; and is about feven miles in circumference. E. Long. 11. 55. N. Lat. 45. 24. . PADUANO, a fmall province of Italy, in the ter¬ ritory of Venice, bounded on the eaft by the Dogado, on the fouth by the Poldino di Rovigo, on the weft by the Veronefe, and on the north by the Vicentino. Its foil is well watered; and is one of the mod fertile in Italy. The province is about 40 miles in length, and 35 in breadth. Padua is the capital town. PADUAN, among the medalifts, a modern medal ftruck in imitation of the antique, or a new medal ftruck with all the marks and chara&ers of antiquity. This name is properly applicable to thofe medals only that were ftruck, in the feventh century, by an Ita¬ lian painter, born at Padua ; who fucceeded fo well in the impofture, that the beft judges are at a lofs to diftinguilh his medals from the genuine ones. Tho’ it is frequently ufed in general for all medals of this kind. PADUS, anciently called Eridanus, efpecially by the Greeks; a river famous for the fable of Phaeton, (Ovid). It rifes in mount Vefulus, in the Alpes Co- thias, from three fprings, dividing the Cifalpine Gaul into the Tranfpadana and Cifpadana, (Strabo) ; and, fwelled by other rivers falling into it on each fide from the Alps and Appennines, it difcharges itfelf with a courfe from weft to eaft, at feven mouths, into the A- driatic, (Mela). The lake thro’ which it difcharges it¬ felf into the fea, is called by the natives the Seven Seas. Now the Po. PADUS, in botany. See Prunu*. PjEAN, among the ancient pagans, was a fong of rejoicing fung in honour of Apollo, chiefly ufed on oc- caiions of victory and triumph. See Apollo. P^an, in the ancient poetry, a foot confilling of four fyllables; of which there are four kinds, the paean pri¬ mus, fecundus, &c. The paean primus confifts of one long fyllable and three fhort ones, or a trochasus and pyrrhichius, as temporibus; the paean fecundus confifts of a fhort fyl- iable, a long, and two fhbrt, or an iambus and a pyr¬ rhichius, as potentia ; the paean tertius confifls of two fhort fyllables, a long and a fhort one, or a pyrrhichius and a trochaeus, as animatus; the pasan quartus confifts of three fhort fyllables and a long one, or a pyrrhichius and iambus, as celeritas. PiEDO-baptism; infant-baptifm, or that conferred on children. PiEONIA, Piony; a genus of the digynia order, belonging to the polyandria clafs of plants. There are two fpecies, both of them very hardy, and will flourifh in any common foil. They are large herbaceous flow¬ ery perennials, with tuberous roots, fending up ftrong annual {talks from one to three feet in height; termi¬ nated by very large flowers of a beautiful red colour, and much larger than any rofe. The common offici¬ nal, or male piony, alfo is remarkable for its capfules turning backward, opening and difplaying their red iafide, together with the numerous feeds, in a Angular¬ ly agreeable order, appearing very ornamental after the IhcfUim flower is paft. The plants may be propagated either I by parting the roots, or by feed. This plant was for- Pagninu* merly celebrated in nervous diftempers, but the pre* fent pra&ice pays very little regard to it. PJESTUM, called Poftdotiia by the Greeks, a town of Lucania, on the Sinus Pseftinus: an ancient colony prior to the firft Punic war, according to Livy ; but later, according to Velleius. Peejlanse rofa were in great efteem, and -produced twice a-year. (Virgil, PAGAN, a heathen, gentile, or idolater; one who adoies falfe gods. See Mythology. PAGANALIA, certain feftivals obferved by the ancient Romans in the month of January. They were inftituted by Servius Tullius, who appointed a certain number of villages (pdgi), in each of which an altar was to be raifed for annual facrifices to their tutelar gods; at which all the inhabitants were to affift, and give prefents in money, according to their fex and age, by which means the number of country-people was known. The fervants upon this occafion offered cakes to Ceres and Tellus, to obtain plentiful harvefts. PAGANELLUS, in ichthyology. See Gobius, PAGANISM, the religious worfhip and difcipline of pagans; or, the adoration of idols and falfe gods. See Idolatry and Mythology. PAGEANT, a triumphal car, chariot, arch, or other like pompous decoration, varioufly adorned with, colours, flags, &c. carried about in public fhews, pro- Ccffions, &c. . PAGI (Antony), a very famous Cordelier, and one of the able ft critics of his time, was born at Rogne in Provence in 1624. He took the habit in the convent at Arles in 1641, and was at length four times pro¬ vincial of bis order; but his religious duties did not prevent his vigorous application to the ftudy of.xhro- nology and ecclefiaftical hiftory, in which he excelled. His moft confiderable work is, “ A Critique upon the Annals of Baronins;” where, following the learned car¬ dinal year by year, he has'reftified an infinite number of millakes, both in chronology and in the reprefenta- tion of fads. He publiflted the firft volume in 1689, dedicated to the clergy of France, who allowed him a penfion : the whole was *printed after his death, in 4 vols, folio, at Geneva, in 1705, by the care of his nephew Francis Pagi, of the fame order. He wrote fome other things before his death, which happened in 1699; and had the chara&er of an able hiftorian as well as of a learned and candid critic. His nephew, Francis, above mentioned, wrote “ A Chronological Abridgment of the hiftory of the Popes,” in Latin, 3 vols, 410. Francis had alfo a nephew, Anthony Pagi, who added three more volumes to the Hiftory of the Popes ^ of which two m6re were intended, if not exe¬ cuted. PAGNINUS (Sandes), a Dominican, illuftn’ous for his {kill in the Oriental languages, was born at Lucca in 1466.' He applied himfelf to examine the vulgar tranflation of the Scriptures; and believing it to be either not of Jerom, or greatly corrupted, he un¬ dertook a new one from the prefent Hebrew text. It appears by a letter from Picus MirUndula to him, that he fpent 23 years on this work, which is the firft mo¬ dern tranflation from the Hebrew; and the Jews who read P A I [ 5798 ] P A I read it, affirmed it to be more exa& than the ancient tranflations: this, however, was his fault; for his fcru- pulous fervile adherence to the letter of the original text, has, according to father Simon, made his tranfla- tion obfeure, barbarous, and full of folecifms. He af¬ terward tranflated the NewTeftament from the Greek, as he had done the Old from the Hebrew, laying the Vulgar all the while before him ; and dedicated it to pope Clement VII. He was alfo the author of a He¬ brew Grammar and Lexicon, which Buxtorf made great ufe of in compiling his; and died in 1536. PAGOD, or Pagoda, a name whereby the Eaft Indians call the temples where they worfhip their gods. Pagod, or Pagoda, is alfo the name of a gold and lilver coin, current in feveral parts of the Eaft Indies. PAIN. See MxTAPHysics, n° 23, 71. As the brain is the feat of fenfation, fo it is of pain. Boerhaave, and moft other authors on this fubjeft, affign a ftretching of the nerves as the only immediate caufe of pain: but as the nerves do not ap¬ pear to coniift of fibres, this caufe of pain does not feem to be well-founded; nor indeed will it be eafy to treat this fubjeft clearly, but in proportion as the means of fenfation are underftood. Many kinds of pain are met,with in authors : fuch as, Agravitative pain; in which there is a fenfe of weight on the part affefted, which is always fome flelhy one, as the liver, &c. A pulfative pain ; which, Galen fays, always fucceeds fome remarkable inflammation in the containing parts, and is obferved inabfcefTes while fup- purating. A tenfive pain, which is alfo called a dijlend- ing pain ; it is excited by the diftenfion of fome ner¬ vous, mufcular, or membranous part, either from fome humour, or from flatulence. An acute pain is, when great pain is attended with quick and lively fenfations: A dull pain is, when a kind of numbnefs is as much com¬ plained of as the pain is. The mediate and more remote caufes of pain are ge¬ nerally obvious; and when fo, the cure will confift for the moft part in removing them: for though in many inftances the chief complaint is very diftanl from the feat of thefe caufes, yet their removal is the proper me¬ thod of relief. See Medicine, Perhaps all pains maybe included, with irritation, in thofe that have fpafm or inflammation for their fource. When pain is owing to inflammation, the pulfe ?is quicker than in a natural ftate; it is alfo generally full, hard, and tenfe; the pain is equal, throbbing, and un¬ remitting. If a fpafm is the caufe, the pulfe is rarely affe&ed; at intervals the pain abates, and then returns with fome degree of aggravation ; gentle motion fome- times abates, or even cures, in fome inftances: but in inflammatory cafes no fuch effedts are ever experien¬ ced. See Dr Lobb’s Treatife on Painful Diftempers. The pain fo frequently attendant on child-bed wo¬ men, called after-pains (from their happening only after being delivered of a child), are often occafioned by fcooping to fetch away coagulated blood, which is a needlefs endeavour. When no improper treatment in delivering the fecundines can be fufpefled, the irri¬ tability of the uterus alone is to be confidered as the caufe. Care fhould be taken not to confound thefe af¬ ter-pains with, or miftake the pains attending puerpe¬ ral fevers for, the colic. After-pains come by fits, and foon go off; but return at different intervals, which are longer each day, and after two or three days are ufu- ally at an end, thoiugh fometimes they continue feven or eight: notwithftanding thefe pains, the lochia flow properly, and generally more abundantly after the cef- fation of each fit; this does not happen in colicky com¬ plaints, nor is the belly fo free from tumefa&ion when the purperal fever is attendant. As thefe pains are of the fpafmodic kind, anodynes and gentle opiates, with frequent draughts of warm caudle, camomile tea, &c. are all that are required in order to their relief. Among the various caufes of pain, a fingular one is related in the third vol. of the Lond. Med. Obf and In q. p. 241, &c. Some perfonswho had taken cold dnring their being falivated, were afflifted with pains which refifted all the ufual methods of relief: at length the author of the narrative referred to, fuggefted the caufe; and by exciting a frefh falivation, the pains abated ; the fpittingwas kept up a little while, and permitted to abate with fome caution; and thus the cures were completed. Pain PAIN yjA-INTING is the art of reprefenting to the eyes, ■*- by means of figures and colours, every objedt in nature that is difcernible by the fight; and of fome¬ times expreffing, by figures, the various emotions of the mind. 1. It is to be imagined that men muft naturally and very early have conceived an idea of the firft principles of the art of painting: the (hadow of each plant and animal, and of each edifice, muft have afforded them the means of conceiving the method of imitating the figures of all bodies whatever. But as in the firft ages of the world the art of writing was unknown, as man¬ kind were ignorant of aftronomy, and as their year cer¬ tainly did not confift of the fame number of days as does that of the moderns, how is it poffible to deter¬ mine the epoch, the precife date, of the rife of each art or fciencei The Egyptians pretend that painting was irt TING. ufe among them many ages before it was known among theGreeks: And the matter is highly probable; for the Egyptians being the moft ancient people, the Greeks drew from them many other'branches of learning; the hieroglyphics of the former were, moreover, a fort of painting. Diodorus Siculus, l. it. c. 4. relates, that Semiramis, having re-eftabliftied Babylon, built there a wall of two leagues and a half in circumference, the bricks of which were painted before they were burnt, and reprefented various kinds of animals. He adds, that fhe had another wall, on which were the figures of all forts of animals painted in their natural colours: and that there were among them even- pidtures which reprefented hunting-matches and combats. This is, in faft, an anecdote of great antiquity. 2. The Greeks were acquainted with the art of wri¬ ting: they were highly oftentatious, and hadamongtbem mea 5799 Part I. PAIN men of real genius. This was fufficient to make them attribute the invention cf all the arts and fciences to tbemfelves. Their authors, however, do not agree about the inventor of painting. Pliny, in his Natural Hirtory, /. xxxv. c. 12. affures us, that Dibutades, a potter of Sicyonia, invented the art of making figures in clay; but that he owed the .invention to his daugh¬ ter, who, on taking leave of her lover that was going to a diilant country, contrived to trace on_a wall, by the means of a lamp, the outline of his fhadow: the father, by applyiugj his clay to thofe lines, formed a ftatue, which he hardened in his ftove; and which was preferved in the tentple of the Nymphs, till the time that Mummius fignalized himfelf by the deftru&ion of Corinth. Love, therefore, was the firft: mafter of paint¬ ing; and that god feems, at this day, to have renewed in France that method of the Greeks, by thofe por¬ traits drawn from fhadows, which they call a la Sil¬ houette. It Ihould feem, however, that neither the Greek hiftorians, nor Pliny, were acquainted with that book of Mofes intitled Genejis; for they would have there feen, in the xxxi chapter, that Rachel, the wife of Jacob, ftole from her father Laban his images, or little figures of houfehold gods; which was in the time of the higheft antiquity : that Aaron afterwards made in the defart a golden calf; that the ark of the cove¬ nant of the Hebrews was ornamented with figures of cherubims ; that Mofes forbad the people the ufe of images: all of which fuppofes a knowledge of defign. Be this as it may, the Greeks feem to have carried the art to great perfe&ion ; if we may believe the fto- ries related of their Apelles and Zeuxis. 3. The Romans were not without confiderable matters in this art, in the latter times of the republic, and un¬ der the firft emperors ; but the inundation of barba¬ rians, who ruined Italy, proved fatal to painting, and TING. almoft reduced it to its firft elements. It was in Italy, however, that the art returned to its ancient honour, and in the beginning of the 15th century; when Ci- mabue, betaking himfelf to the pencil, tranflated the poor remains of the art, from a Greek painter or two, into his own country. He was feconded by fome Flo¬ rentines. The firft who got any reputation was Ghir- landai, Michael Angelo’s mafter; Pietro Pcrugino, Ra¬ phael Urbin’s matter; and Andrea Verocchio, Leo¬ nardo Da Vinci’s mafter. But live fcholars far furpaf- fed the matters; they not only effaced all that had been done before them, but carried painting to the high¬ eft perfe&ion of which it is capable. It was not by their own noble works alone that they advanced paint¬ ing ; but by the number of pupils they bred up, and the fchools they formed. Angelo, in particular, found¬ ed the fchool of Florence; Raphael, the fchool of Rome; and Leonardo, the fchool of Milan ; to which muft be added the Lombard fchool, eftablifhed about the fame time, and which became very confidei;able under Gior¬ gione and Titian. Btfides the Italian mafters, there were others on this fide the Alps, who had no communication with thofe of Italy: fuch were Albert Durer, in Germany; Hol- bens, in Switzerland; Lucas, in Holland; and others in France and Flanders. But Italy, and particularly Rome, was the place where the art was praftifed with the greateft fuccefs; and where, from time to time, the greateft mafters were produced. To Raphael’s fchool, fucceeded that of the Carac- cios; which haslafted, in its fcholars, almofl; to the pre¬ fen t time. It is of the different parts of this art thus re-efta- blifhed, extended, and improved, that we are here to treat. PART I. Principles of the Art, and the Order of the Artifl’s Studies. Sect. I. Of the Fir ft Exercifes of a Painter. 4. TT is not a matter of fo little importance, as fome are, perhaps, apt to imagine, upon what drawings a pupil is firft put to exercife his talents. Let the firft profiles, the firft hands, the firft feet, given him to copy, be of the beft mafters, fo as to bring his eye and his hand early acquainted with the moil elegant forms, and the moft beautiful proportions. A youth, employed in copying the work of a middling painter, in order to proceed afterwards to fomething of Raphael’s, having faid, in the hearing of a matter, That he did it in or¬ der to bring his hand in ; the mafter, as fenfibly as wittily, replied, “ Say rather, to put it out.” A pain¬ ter, who has early acquired a fine ftyle, finds it an eafy matter to give dignity to the meaneft features, while even the works of a Praxiteles or a Glycon are fure to fuffer in the hands of another. A veffel will ever’retain the feent which it has firft contrafted. It would be proper alfo to make the pupil copy fome fine heads from the Greek and Roman medals: not fo much for the reafons juft now laid down, as to make him acquainted, if we may ufe the expreflion, with thofe perfonagts which in time he may have occafion to introduce into his pieces; and, above all, to improve him Vol. VIII. i early in the art of copying from relief. Hence he will learn the rationale of light and lhade, and the nature of that chiar-ofcurot by which it is, properly fpeaking, that the various forms of things are diftinguiftied. To this it is owing, that a boy will profit more by draw¬ ing after things in relief, though but meanly executed, than by copying the moft; excellent drawings. But, whatever he does, care (hould be taken to make him do it with delight, and finifh it in the moft accurate man¬ ner. Nothing in the world is fo neceflary as diligence; efpecially at the firft entrance upon any ftudy. Nor muft he ever expe£ to have the compaffes in his eye, who has not firft had them for a long time in his hand. Sect. II. Of Anatomy. 5. To a Ik if the ftudy of anatomy is requifite to a painter, is the fame thing as to.afk if, in order to learn any fcience, a man muft firft make himfelf acquainted with the principles of it. It would be throwing away time to cite, in confirmation of this truth, the autho¬ rities of the ancient mafters, and the moft celebrated fchools. A man, who is unacquainted with the form and conftru&ion of the feveral bones which fupport and govern the human frame, and does not know in what manner the mufcles moving thefe bones are fixed to 32 S them, 5808 P A I M Anatomy, tliem, can make nothing of what appears of them thro’ “ the integuments with which they are covered ; and ■which appearance is, however, the nobleft objeft of the pencil. It is impoffible for a painter to copy faithfully what he fees, unlefs he thoroughly underftands it. Let him employ ever fo much time and ftudy in the at¬ tempt, it cannot but be attended with many and great miftakes: juft as it muft happen to a man, who under¬ takes to copy fomething in a language which he does not underhand; or to tranflate into his own, what has been written in another, upon a fubjeft with which he is not acquainted. It feldom happens, that nothing more is required of a painter than to copy exaftly an objeft which he has before him. In ftill and very languid attitudes, in which every member is to appear motionlefs and dead, » living mqdel may, no doubt, yield for a long time a faithful image, an'd prove an ufeful pattern to him, But in regard to gellures any way fudden, motions any way violent, or thofe momentary attitudes which it is more frequently the painter’s bufinefs to exprefs, the cafe is quite different. In thefe a living model can hold but an inftantor two; itfoon grows languid, and fettles into a fixed attitude, which is produced by an inftan- taneous concourfe of the animal-fpirits. If, therefore, a painter poffeffes not fo thoroughly all the principles of anatomy, as to be at all times able to have imme¬ diate recourfe to them ; if he knows not the various manners in which the feveral parts of the human body play, according to their various pofitions; living mo¬ dels, far from proving an ufeful pattern to him, will rather tend to lead him aftray, and make him lofe fight of truth and nature, by exhibiting the very reverfe of what is required, or at leaft exhibiting it in a very faint and imperfeft manner. In living models, we often be¬ hold thofe parts flow, which fhould be very quick; thofe cold and torpid, which fhould have the greateft fhare of life and fpirit in them. Nor is it, as fome may be apt to imagine, merely to reprefent athletic and vigorous bodies, in which the parts are moft bold and determined, that anatomy is requifite: it fhould be underftood, to reprefent perfons of the moft delicate frame and condition, even women and children, whofe members are fmootheft and rounded, though the parts made known by it are not to be ftrongly expreffed in fuch objects; juft as logic is equally requilite under the polifhed infinuations of the orator and the rough arguments of the phi- lofopher. But it is needlefs to fpend much time in proving, that a painter fhould be acquainted with anatomy; or in fhowing, how far his acquaintance with it fhould extend. For inftance, it is unneceffary for him to enter into the different fyftems of the nerves, blood- veffels, bowels, and the like ; parts which are re¬ moved from the fight, and which therefore may be left to the furgeon and the phyfician, as being a guide in the operations of the former and in the pre- fcriptions of the latter. It is enough for the painter, to be acquainted with the fkeleton ; in other words, with the figure and coneflion of the bones, which are, in a manner, the pillars and props of the human body ; the origin, progrefs, and fhape, of the mufcles, which cover thefe bones ; as alfo the different degrees which nature has cloathed the mufcles with fat, TING. Part I. for this fubftance lies thicker upon them In fome Anat.my, places them in others. Above all, he fhould know, in what manner the mufcles effeft the various mo¬ tions and geftures of the body. A mufcle is compofed of two tendinous and flender parts, one called the head, the other the tail, both terminating at the bones; and of an intermediate part, called the belly. The aftion of a mufcle confifts in an extraordinary fwelling of this intermediate part, while the head remains at reft, fo as to bring the tail nearer the head, and confe- quently the part, to which the tail of the mufcle is fixed, nearer to that part into which the head is in- ferted. There are many motions, to effedf which feveral of the mufcles (for this reafon called co-operating mufcles) muft fwell and operate together, while thofe calculated to effedt a contrary motion (and therefore called anta- gonifl mufcles) appear foft and flaccid. Thus, for ex¬ ample, the biceps and the brachiasus internus labour when the arm is to be bent, and become more promi¬ nent than ufual; while the gemellus, the brachiseus externus, and the anconaeus, whofe office is to extend the arm, continue, as it were, flat and idle. The fame happens refpe&ively in all the other motions of the body. When the antagonift mufcles of any part operate at one and the fame time, fuch part becomes rigid and motionlefs. This adtion of the mufcle is called tonic. / Michael Angelo intended to have given the public a complete treatife upon this fubjeft ; and it is no fmall misfortune, that he never accomplilhed fo uftful a defign. This gre^t man, having obferved, as we are told in his life by Condivi, that Albert Durer was deficient on the fubjeft, as treating only of the various meafures and forms of bodies, without faying a word of their attitudes and geftures, though things of much greater importance, refolved to compofe a theory, founded upon his long praftice, for the fervice of all future painters and ftatnaries. And, certainly, no one could be better qualified to give anatomical pre¬ cepts for that purpofe, than he, -who, in competition with Da Vinci, defigned that famous cartoon of naked bodies, which was ftudied by Raphael hirrrfelf, and afterwards obtained the approbation of the Vatican, the greateft fchool of the art we are now treating of. The want of Michael Angelo’s precepts may, in fome meafure, be fupplied by other books written on the fame fubjeA by Moro, Cefio, and Tortebat ; and lately by Boucherdon, one of the moft famous ftatu- aries in France. But nothing can be of equal fervice to a young painter, with the leffons of fome ablediffec- tor; under whom, in a few months, he may make himfelf mafter of every branch of anatomy which he need to be acquainted with. A courfe of ofteology is of no great length: and of the infinite number of mufcles difcovered by curious myologifts, there are not above 80 or 90, with which nature fenfibly operates all thofe motions which he can ever have occafion to imitate or exprefs. Thefe, indeed, he ftiould clofely ftudy, thefe he Ihould carefully ftore up in his memory, fo as never to be at the leaft lofs for their proper figure, fituation, office, and motion. But there is another thing befides the difle&ion of dead bodies, by which a young painter may profit greatly; and that is, anatomical calls. Of thefe we have Part I. PAIN Anatomy, have numbers by feveral authors; nay fome, which " pafs under the name of Buonarroti himfelf. But there is one, in which, above all the reft, the parts are moft diftin&ly and lively exprefled. This is the perfor¬ mance of Hercules Lelii, who has, perhaps, gone greater lengths in this kind of ftudy than any other mailer. We have, befides, by the fame able hand, ibme cafts of particular parts of the human body, fo curioufly coloured for the ufe of young painters, as to reprefent thefe parts exatily as they appear on re¬ moving the integuments ; and thus, by the difference in their colour as well as configuration, render the tendinous and the flefhy parts, the belly and the ex¬ tremities, of every mufcle fuprifingly diftinft; at the fame time that, by the various diredion of the fibres, the motion and play of thefe mufcles become very obvious ; a work of the greateft ufe, and never enough to be commended! Perhaps, indeed, it would be an improvement, to give the mufcles various tints; thofe mufcles efpecially, which the pupil might be apt to miftake for others. For example, though the maftoi- des, the deltoides, the fartorius, the fafeia lata, the gafterocnemii, are, of themfelves, fufficiently diftin- guifhable, it is not fo with regard to the mufcles of the arm and of the back, the right mufcles of the belly, and fome others, which, either on account of the many parts into which they branch, or of their being interwoven one with another, do not fo clear- ' ly and fairly prefent themfelves to the eye. But let the caufe of confufion to young beginners be what it will, it may be effe'dually removed by giving, as already hinted, different colours to the different muf¬ cles, and illumining anatomical figures; in the fame manner that maps are, in order to er^able us readliy to diftinguifh the feveral provinces of every kingdom, and the fcveral dominions of every prince. The better to underftand the general effefl, and remember the number, fituation, and play of the mufcles, it will be proper to compare, now and then, the anatomical cafts, and even the dead body itfelf, with the living body covered with its fat and Ikin ; and above all things, with the Greek ftatues ftill in being. It was the peculiar happinffs of the Greeks, to be able to chara&erize and exprefs the feveral parts of the human body much better than we can pretend to do; and this, on account of their particular appli¬ cation to the ftudy of naked figures, efpecially the fii e living ones which they had continually before their eyes. It is well known, that the'mufcles moft ■fed are likewife the moft protuberant and confpi- cuous ; fuch as, in thofe who dance much, the muf¬ cles of the legs; and in boatmen, the mufcles of the back and arms. But the bodies of the Grecian youth, by means of their conftant exertion of them in all the gymnaftic fports, were fo thoroughly exercifed, as to fupply the ftatuary with much more perfeft models than ours can pretend to be. It is not to be doubted, but that, for the fame reafon, the Greek painters at¬ tained the higheft degree of perfection in the figures of thofe pieces of theirs fo much cried up by ancient authors; and it is a great pity, that we have not even thofe copies of nature to diredl our ftudies. For the faults obCervable in the ancient paintings, which have been dug up in great numbers, efpecially within thefe few years, do not fo much tend to prove that the 2 TING. 5801 Greeks were any Way deficient in this art, as the Anatomy, pieces themfelves, taken all together, that they had * carried it to the higheft degree of perfection. For, if in pictures drawn upon walls, which it was therefore impofiible to refeue from fire, and in little country towns, and at a time when the art was at its lowett ebb, there appears, in the opinion of the beft judges, fuch excellence of defign, colouring, and compofition, that one would apt to atribute melt of them to the fchool of Raphael; what muft we think of the pictures, drawn at an earlier period, by their ableft mailers and for their moft flourifhing cities and moft powerful mo- narchs; of picture* admired in a country like Greece, where every art was brought to fuch a degree of per¬ fection, that no paffion could refill their mufic, no fen- timent refill their mimic arts ; of pictures cried up a# Pliny *, the foundnefs of whole judgment in matters jjb xxxv/ * this kind difplays itfelf in fo many palfages of his works; e. i j, collefted at fuch expence by Julius Casfarf, ofwhofefinef Suetonius, tafie, the works compofed by him, and Hill extant, are ain Vlt* Cael- moft inconteftable proof? But what evinces ftill bettercap* theexcellenceof theancients in painting, is that to which they arrived in ftatuary, her fitter art. Both daughters of defign, they both enjoyed in commonthefame models, which, more perfeCt in the happy climate of Greece than in any other part of the globe, mult have been of as great fervice to the Apellefes and the Zeuxifes, in the drawing of their figures, as they were to the Apol- loniufes, the Glycons, and the Agahes, in carving thofe' ftatues which the world has ftill the happinefs of pofftf- fing. Thefe mailers, being befides affilted by a proper infight into anatomy, and thoroughly acquainted with the various play of the mufcles acecording to the va¬ rious attitudes of the body, and with the different de¬ grees of ftrength with which each particular mufcle was to be expreffed in each particular attitude, were thereby enabled to give truth, motion, and life, to all their works. There are a great many exercifes, which a young painter fhould go through while engaged in the ftudy of anatomy, in order to make himfelf more thoroughly mailer of that fcience. For example : The thighs of any figure, a Laocoon for inftance, being given, he Ihouldadd to them legs fuitable to that ftate in which the mufcles of the thighs are reprefented, that is, the mufcles which ferve to bend and extend the legs, and to effeCiuate in them fuch a precife pofition and no other. To the lirnple contour of an anatome, or a ftatue, he fhould add the parts included by it, and give it a fyftem of mufcles conformable to the quality of that particular contour; for every contour denotes fome one certain attitude, motion, exertion, and no other. Exercifes of this kind would foon eftablilh him in the moft fundamental principles of painting, efpecially if he had an opportunity of comparing his drawings with the ftatue or call from which the parts given him to work upon were taken, and thereby dif- covering and correcting his miftakes. This method is very like that ufed by thofe who teach the Latin tongue ; when, having given, their fcholars a paffage of Livy or Casfar already tranflated into their mother- tongue, to tranllate back into Latin, they make them compare their work with the original next. Sect. III. Of Perfpeftive. 6* Tfifi ftudy of perfpeCtive Ihould go hand in band 3282 witfi 5802 PAIN Perfpeaive. with that of anatomy, as not lefs fundamental and ~ neeeflary. In faft, the contour of an objeft drawn upon paper or canvas, reprefents nothing more than fuch an interfe&ion of the vifual jays fent from the extremities of it to the eye, as would arife on a glafs put in the place of the paper or canvas. Now, the fituation of an objeft at the other fide of a glafs being given, the delineation of it on the glafs itfelf depends entirely on the fituation of the eye on this fide of the glafs ; that is to fay, on the rules of perfpedtive : a fcience which, contrary to the opinion of moft people, extends much farther than the painting of fcenes, , floors, and what generally goes under the name of quadratura. Perfpe&ive, according to that great inafter da Vinci, is to be confidered as the reins and rudder of painting. It teaches in what proportion the parts fly from, and leflen upon, the eye ; how fi¬ gures are to be marflialled upon a plain furface, and fore-fhortened. It contains, in fhort, the whole ra¬ tionale of defign. Such are the terms which the mailers bell ground¬ ed in their profefiion have employed to define and commend perfpe&ive: fo far were they from calling it a fallacious art., and an infidious guide; as fome amongft the moderns have not blulhed to do, infilling that it is to be followed no longer than it keeps the high road, or leads by eafy and pleafarit paths. But thefe writers plainly Ihow, that they are equally ig¬ norant of the nature of perfpe&ive, which, founded as it is on geometrical principles, can never lead its vo¬ taries allray; and of the nature of their art, which, without the affiftance of perfpeftive, cannot, in rigour, expedt to make any progrefs, nay, not fo much as delineate a Ample contour. Thofe, too, w'lio would perfuade us, that the ancient mailers of Greece knew nothing of perfpeftive, fhow, that they themfelves know little or nothing of paint-ing. They allege, as a proof of this their idle affertion, that the rules of perfpe&ive are violated in the moft of the ancient pi&ures that have reached us 5 as though the miftakes and blunders of middling artifts were a fufficient ground for calling in queftion the merit of others, who were allowed to excel in their *■ profefiion. Now, not to infill on the abfurdity of fuch a fuppofition, which we have already expofed, Pamphilus, the mailer of Apelles, and the founder of the nobleft fchool of all Greece, has affirmed in the moft exprefs terms, that, without geometry, painting fPHnii mull fall to the ground f. It is well known, befides, Lb^xxxv t^iat t^e anc‘cnts Pra&ifed the art of painting in per- c. 10. * fpe&ive upon walls, in the fame way that it is now done * Vitruvius,by the moderns*; and that one of the walls of the ilb.vii. c. j. theatre of Claudius Pulcher, reprefenting a roof co¬ vered with tiles, was finilhed in fo mafterly a manner, that the rooks, a bird of no fmall fagacity, taking it \.TPUn. for a real roo^ often attempted to alight upon it J. Hb^'xxxv are hkewife told, that a dog was deceived to fuch c, 4, ' a degree, by certain Heps in a perfpe£tive of Dento’s, that, expedting to find a free paflage, he made up to them in full fpeed, and dalhed cut his brains; thus immortalizing by his death the pe icil of the artift, which had'been the occafion of it. But, what is Hill U” ^ more, Vitruvius || tells us in exprefs terms, by whom, 1 ' vu‘ and at what time, this art was invented. It was firft pradtifedby Agatharcus, a contemporary of iEfchylus, TING. Part I. in the theatre of Athens ; and afterwards reduced t o Perfpetfive, certain principles, and treated as a fcience, by Anaxa- — — goras and Democritus; thus faring like all other arts, which exifted in pradtice before they appeared in the¬ ory. The thing, perhaps, may be thus accounted for. Some painter, who happened to be a very ac¬ curate obferver of nature, firft exadlly reprefented thofe effefls which he faw conftantly attend the images offered to our eyes by exterior objedls ; and thefe effedls came afterwards to be demonltrated by geome¬ tricians as fo many necefiary confequences, and re¬ duced to certain theorems: juft as from thofe chef d’ceuvres of the human mind, the Iliad of Homer, . and Oedipus of Sophocles, both built upon the moft accurate obfervations of nature, Ariftotle found means to extradl the rules and precepts contained in his art of poetry. It is therefore clear, that, fo early as the age of Pericles, perfpedtive was reduced into a com¬ plete fcience; which no longer continued confined to the theatre, but made its way into the fchools of painting, as an art not lefs necefiary to painters in general, than it had been found to feene-painters in particular. Pamphilus, who founded in Scion the moft flourifhing fchool of defign, taught it publicly : and from the time of Apelles, Protogenes, and the other bright luminaries of painting amongft the an¬ cients, it was praftifed by the Greek painters, in the fame manner that it was, fo many ages after, by Bellini, Pietro Perugino, and others, down to the days of Titian, Raphael, and Corregi, who put the laft hand to painting, and gave it all that, perfeftion it was capable of receiving. Now, a painter having formed a feene in his mind,, and fuppofed, as it is cuftomary, that the capital fi¬ gures of this feene lie clofe, or almoft clofe, to the back of his canvas, he is, in the next place, to fix upon fome point on this fide of the canvas, from which he would choofe his piece ftiould be feen. But in choofing this point, which is called the point of fight, regard (hould be had to its fituation to the right or left of the middle of the canvas: but, above all things, to its diftance and its height with refpeft to the lower edge of the canvas ; which edge is called the hafe line, and is pa¬ rallel with the horizontal line that paffes through the eye. For by affuming the point of fight, and confe- quently the horizontal line, too low, the planes, upon which the figures Hand, will appear a great deal too fhallow; as, by affuming it too high, they will appear too fteep, fo as to render the piece far lefs light and airy than it ought to be. In like manner, if the point of fight is taken at too great a diftance from the can¬ vas, the figures will not admit of degradation enough to be feen with fufficient diftin&ntfs ; and if taken too near it, the degradation will be too quick and precipi¬ tate to have an agreeable effeft. Thus, then, it ap-~ pears, that no fmall attention is requifite in the choice of this point. When a pifture is to be placed on high, the point of fight (hould be affumed low, and vice verfa ; in or¬ der that the horizontal line of the picture may be, as near as poffible, in the fame horizontal plane with that of the fpe&ator; for this difpolition has an amazing effect. When a pifture is to be placed very high, as, amongft many others, that of the purification by Pao¬ lo Veronefe, engraved by le Fevre, it will be proper to- Part. I. Perfpeftive. to aflume tTie point of fight fo low, that it tnay lie quite under the picture, no part of whofe ground is, in that cafe, to be vifible ; for, were the point of fight to be taken above the picture, the horizontal ground of it would appear Hoping to the eye, and both fi¬ gures and buildings as ready to tumble head foremott. It is true, indeed, that there is feldom any necelTity for fuch extraordinary exa&nefs ; and that, unlefs in fome particular cafes, the point of fight had better be rather high than low: the reafon of which is, that, as we are more accufteiped to behold people on the fame plane with ourfelves, than either higher or lower, the figures of a piece mult (trike us molt when handing on a plane nearly level with that upon which we our¬ felves hand. To this it may be added, that by pla¬ cing the eye low, and greatly fhortening the plane, the heels of the back figures will feem to bear againlt the heads o£ the foremolt, fo as to render the diftance / between them far lefs perceptible than otherwife it would be. The point of fight being fixed upon, aceording to the fituation in which the pidture is to be placed, the point of diftance is next to be determined. In doing _ this, a painter fhould carefully attend to three things: firft, that the fpe&atbr may be able to take in, at one glance, the whole and every part of the compofuion ; fecondly, that he may fee it diftin&ly ; and thirdly, that the degradation of the figures and other objefts of the pidture be fufficiently fenfible. It would take up too much time to lay down certain and precife rules for $oing all this, confidering the great varie¬ ty in the fizts and fhapes of pidtures; for which rea¬ fon we muft leave a great deal to the difcretion of the painter. But there is a point ftill remaining, which will riot admit of the lead latitude. This is, the delineation of the pidture, when once the point of fight has been fix¬ ed upon. The figures of a pidlure are to be confider- ed as fo many columns eredted on different fpots of the fame plane ; and the painter muft not think of de- figning any thing, till he has laid down, in perfpec- tive, all thofe columns which are to enter his compo- fition, with the moll fcrupulous exadtnefs. By pro¬ ceeding in this manner, he may not only be fure of not committing any miftake in the diminution of his figures according to their different dillances, but may flatter himfelf with the thoughts of treading in the fteps of the greateft mailers, efpecially Raphael, in whofe (ketches (fuch was his refpedt to the laws of perfpedlive) we frequently meet with a fcale of de¬ gradation. It is to the pundtual obfervance of thefe laws, that we are to attribute the grand effedl of Tome paintings by Carpazio and Mantegna, fo carelefs in other refpedls ; whereas a Angle fault againft them is often fufficient entirely to fpoil the works of a Gui- * do, in fpite of the fublimity and beauty of his fupe- rior ftyle. Now, as the demonftration of the rules of perfpec- tive depends on the dodtrine of proportions, on the properties of fimilar triangles, and on the interfedtion of planes, it will be proper to put an abridgement of Euclid into the hands of the young painter, that he may underftand thefe rules fundamentally, and not ftaud confined to a blind pradlice of them : but, then, there is nothing in.this author, relative to the art of p.aint- 5803 ing, which may not be eafily acquired in a few months. Symmetry. For, as it would be of no ufe to a painter to lanch' . out into the anatomical depths of a Monro or an Al- binus, it would be equally fuperfluous to perplex bim- felf with the intricacies of the higher geometry with a Taylor, who has handled perfpedlive with that rich profonndnefs, which we cannot help thinking does a great deal more honour to a mathemati¬ cian, than it can poflibly bring advantage to a Ample art iff. But though a much longer time were requifite to become a perfedt mailer of perfpedlive, a painter, fure- ly, ought not to grudge it; as no time can be too long to acquire that knowledge, without which he cannot poflibly expedl to fucceed. Nay, we may boldly affirm, that the (hortell road in every art is that which leads through theory to pradlice. It is from theory that arifes that great facility, by means of which a man advances the quicker, In proportion as he is furer of not taking a wrong ftep: whilft thofe, who are not grounded in the fcience, labour on in perpe¬ tual doubt; obliged, as a certain author expreffes it, to feel out their way with a pencil, juft as the blind, with their Hicks, feel for the ftreets and turnings, with, which they are not acquainted. As pradtice, therefore, ought in every thing to be built upon principle, the ttudyof Optics, as far as it is requifite to determine the degree in which objedts are to be illuminated or (haded, (hould proceed hand in hand with that of perfpedlive : And this, in order that the (hade's, call by figures upon the planes on which they (land, may fall properly, and be neither too ftrong nor too light; in a word, that thofe moll beautiful effedls of the chiar-ofcuro may run no rifle of ever receiving the lie from truth, which fooner or la¬ ter difeovers itfelfto every eye. Sect. IV. Of Symmetry. 7. The ftudy of fymmetry, it is obvious, fliould immediately follow that of anatomy*: for it would avail- us little to be acquainted with the different parts of the human body, and their feveral offices, were we at the fame time ignorant of the order and proportion of thefe parts in regard to the whole in general, and each other in particular. The Greek ftatuaries diftinguifh- ed themfelves above alk others, as much by the juft fymmttry of their members, as by their (kill in anato¬ my;, but Polycletes furpaffed them all by a (latue, call¬ ed the Rule, from which, as from a molt accurate pat-p//n!y tern, other artiils might take meafures for every part Nat. HiJK. of the human body. Thefe meafures, to fay nothing ht}, XX3dVk- of the books which treat profeffedly of them, may nowCi 8- be derived from the Apollo of Belvedere, the Lao- coon, the Venus of Medieis, the Faunus, and parti¬ cularly the Antinous, which laft was the rule of the learned Pouffin. Nature, which in the formation of every fpecies feems to have aimed at the lall degree of perfedtion, does not appear to have been equally folicitous in the production of individuals. She coufiders, one would think, thofe things as nothing, which have a begin¬ ning and an end, and whofe exiffence is of fo (hort a duration, that they may be faid, in a manner, to come into the world merely to leave it. She feems, in fome fort, to abandon individuals to (ecoiid caufes; and if fronfci PAINTING. 5804 Symmetry. from them there now and then breaks forth a primi- ~ live ray-of perfeftion, it is too foon eclipied by the clouds of imperfe&ion that conftantly attend it. Now, Art foars up to the archtypes of Nature ; colle&s the flowers of every beauty, which it here and there meets with ; combines all the perfedl models that come in its way; and propofes them to men for their imita¬ tion. Thus, the painter, who had before him a com- | In Gala- pany of naked Calabrian girls, traced, as la Cafa f in- tca. See al-gen-;ou{]y expreffes it, the refpeftive beauties which they had as it were borrowed from one Angle body; by Carlo ' that, by making each of them reftore to this imagi- Dati, nary form what fhe had borrowed from it, he might note ir. be furniihed with a complete pattern ; rightly imagi¬ ning, that from fuch an union, and of fuch beauties, mufl refult the beauty of an Helen. This was likewife the pra&ice of the ancient ftatuaries, when about to form in brafs or marble the ftatues of their gods or he¬ roes. And, thanks to the hardnefs of thefe materials, fome of their works, containing united all that pof- flble perfeftion which could be found fcattered here and there in individuals, fubfift to this day as patterns not only of exa& fymmetry, but of fupereminent grandeur in the parts, gracefulnefs and contrail in the attitudes; in Ihort, as paragons in every kind, and the very mirrors of beauty. In them we behold precept joined with example : in them we fee where the great mailers of antiquity deviated with a happy boldnefs from the common rules ; or rather made them bend to the different cbara£lers they were to reprefent. In their Niobe, for inftance, which was to breathe majefty like Juno, they have altered fome parts that appear more delicate and flender in their Venus, the pattern of female beauty. The legs and thighs of the Apollo of Belvidere, by being made fomewhat longer than the common proportion- of thefe limbs to the reft of the body feems to admit, contribute not a little to give him that eafe and freedom which correfpond fo well with the aclivity attributed to that deity; as, on the other hand, the extraordinary thicknefs of the neck adds ftrength to the Farnefian Hercules, and gives him fomething of a bull-like look and robuftnefs. It is the general opinion of painters, that the an¬ cients were not as happy in reprefenting the bodies of children, as they are allowed to have been in repre¬ fenting thofe of women and men ; efpectally thofe of their gods ; in which they excelled to fuch a degree, that with thefe gods were often worlhipped the artifts who had carved them. Yet the Venus of Gnidus by Praxiteltes was not more famous than her Cupid, on ■\ Cic. in whofe account alone people flocked to Thefpiae f. To i'rrrem, children, fay they, the ancients knew not how to im- ^ fig™- part that foftnefs and effeminacy, which Fiammingo lib^ix’ has fincecontrived to give them, by.reprefenting their Pli„. cheeks, hands, and feet, fwelled, their heads large, Hifl. and with fcarce any belly. But fuch critics feem to lib. xxxvi. forget, that thefe firft fketches of nature very feldom s‘ come in the painter’s way, and that this puny and de¬ licate ftate has not in its form even the lead glimmer¬ ing of perfedlion. The ancients never undertook to reprefent children lefs than four or five years old ; at which age the fuperfluous humours of the body be¬ ing in fome meafure digefted, their members be¬ gin to affume fuch a contour and proportion, as may fcrve to point out what they are afterwards likely to Part L This obfervation is confirmed by the children Symmetry, which we meet with in ancient baffo-relievos and paint- ings: for they are all doing one thing or another; like thofe moft beautiful little Cupids in a pidlure at Ve¬ nice, who are playing with the arms of Mars, and lift¬ ing up the ponderous fword of that deity; or that little urchin in the Danae of Caracci, who empties a quiver of its arrows, in order to fill it with the golden ftiower. Now, what can be a greater blunder in point of coftume, than to attribute adtions, which require fome degree of ftrength and judgment, to infancy, to that raw and tender age fo totally unable to govern and fuppoft itfelf? Let a young painter confider the Greek ftatues ever fo often, of whatever character or age they may be re- prefented, it is impoflible he fliould ever confider them without difeovering new beauties in them. It is there¬ fore impoflible he fhould copy them too often, accor¬ ding to that judicious motto placed by Moratti on his print called The fchool. This truth was acknowledged by Rubens himfelf: for though, like one bred, as he was, in the foggy climate of the Low Countries, he generally painted from the life ; in fome of bis works he copied the ancients; nay, he wrote atrtatife on the excellency of the ancient ftatues, and on the duty of a painter to lludy and imitate them. As to the fatirical print, or rather pafquinade, of the great Titian, in which he has reprefented a parcel of young monkeys aping the groupe of Laocoon and his fons; he intend¬ ed nothing more by it than to lafh the dulnefs and po¬ verty of thofe artifts, who cannot fo much as draw a figure without having a ftatue before them as a mo¬ del. In fa£l, reafon requires, that an artift fttould be fo much mafter of his art, as feldom to Hand in need of a pattern. To what other purpofe is he to fweat and toil from his infancy, and fpend fo many days and nights in ftudying and copying the bell models ; efpe- cially the fineft faces of antiquity, which we are Hill poftlffed of; fuch as the two Niobes, mother and daughter ; the Ariadne, the Alexander, the young Nero, the Silenus, the Nile; and likewife the fineft figures ; for inftance, the Apollo, the Gladiator, the Venus, and others ; all which (as was faid of Pietro Fdta), he fhould have, as it were, perfeftly by heart? With a flock of excellencies like thefe, treafured up in his memory, he may one day hope to produce fome¬ thing of his own without a model; form a right judge¬ ment of thofe patural beauties which fall in his way ; and, when occaiion offers, avail himfelf properly of them. It is very ill done to fend boys to an academy to draw after naked figures, before they have imbibed a proper relifh for beautiful proportions, and have been well-grounded in the true principles of fymmetry. They fhould firft learn, by ftudying the precious re¬ mains of antiquity, to improve upon life; and difeera where a natural figure is faulty through ftiffnefs in the members, or clumfinefs in the trunk, or in any other refpeft ; fo as to be able to corredl the faulty part, and reduce it to its proper bounds. Painting, in thiV branch, is, like medicine, the art of taking away and adding. It muft not, however, be diffembled, that the me¬ thods hitherto laid down are attended with fome dan¬ ger; PAINTING. be. Part I. PAIN Symmetry, gey • for by too flavifti an attention to ftatues, the — young painter may contraft a hard and dry manner ; and by ftudying anatomies too fervilely, a habit of re- prefenting living bodies as ftripped of their (kin : for, after all, there is nothing but what is natural, that, befides a certain peculiar grace and livelinefs, poffefies that fimplicity, eafe, and foftnefs, which is not to be expefted in the works of art, or even in thofe of nature when deprived of life. Pouffin himfelf has now and then given into one of thefe extremes, and Michael An¬ gelo very often into the other: but from this we can only infer, that even the greateft men are not infallible. It is, in (bore, to be conlhdered as one inftance, among a thoufand, of the ill ufe thofe are wont to make of the beft things, who do not know how to temper and qualify them properly with their contraries. But no fuch danger can arife to a young painter from confining himfelf for a long time to mere defign, fo as not to attempt colouring till he has made him¬ felf mailer of that branch, if, according to a great •f Pouffin; mailer f, colours in painting are in regard to the eye in his Life, what numbers in poetry are in regard to the ear, fo y Bcllori. many charms y0 allure and captivate that fenfe ; may we not affirm, that defign is in the fame art what pro¬ priety of language is in ^writing, and a juft utterance of founds in mufic ? Whatever fome people may think, a pi&ure defigned according to the rules of perfpedive and the principles of anatomy, will ever be held in higher efteem by good judges, than a pidure ill de¬ figned, let it be ever fo well coloured. Annibal Caracci fet fo great a value upon the art of con¬ tour, that, according to fome expreffions of his which have reached us, he confidered almoft every thing elfe as nothing in comparifon with it. And this his judg¬ ment may be juftified, by confidering, that nature, though Ihe forms men of various colours and complec- tions, never operates in their motions contrary to the mechanical principles of anatomy, nor, in exhibiting thefe motions fo the eye, againft the geometrical laws of perfpedive : a plain proof, that, in point of defign, no millake is to be deemed trifling. Hence we are en¬ abled to feel all the weight of thofe words in which Michael Angelo, after he confidered a pidure drawn by a prince of the Venetian fchool, addrefled Vafari: 41 What a pity it is,” faid he, “ that this man did not fet out by ftudying defign !” As the energy of nature ffiines moft in the fmalleft fubjeds, fo the energy of ait Ihines moft in imitating them. Sect. V. Of Colouring. 8. It muft likewife be of great fervice to a painter de- firous to excel in colouring, to be well acquainted with that part of Optics which has the nature of light and colours for its objed. Light, however Ample and uncompounded it may appear, is neverthelefs made up, as it were, of feveral diftind fubftances ; and the num¬ ber, and even dofe, of thefe ingredients, has been hap¬ pily difeovered by the moderns. Every undivided ray, let it be ever fo fine, is a little bundle of red, orange, yellow, green, azure, indigo, and violet rays, which, while combined, are not to be diftinguiffied one from another, and from that kind of light called ’white; fo white is not a colourferje, as the learned da Vin- tteUaPU- C' ^ ^ar> 'hfceros, the precurfor of Newton) exprefs- tura, c. 14. ty affirms, but an affemblage of colours. Now, thefe TING. 580; colours, which compofe light, although immutable in Colouring, themfelves, and endued with various qualities, are con- " tinually, however, feparating from each other in their refledion from and paffage through other fubftances, and thus become manifeft to the eye. Grafs, for ex¬ ample, refleds only green rays, or rather refleds green rays in greater number than it does thofe of any other colour ; and one kind of wine tranfmits red rays, and another yellowiffi rays; and from this kind of fepara - tion arifes that variety of colours with which nature ha» diverfified her various produdions. Man, too, has con trived to feparate the rays of light by making a por¬ tion of the fun’s beams pafs through a glafs prifm ; for after paffing through it, they appear divided into feven pure and primitive colours, placed in fucceffion one by the other, like fo many colours on a painter’s pallet. Now, though Titian, Correggio, and Vandyke, have been excellent colourifts, without knowing any thing of thefe phyfical fubtleties, that is no reafon why others ftiould negled them. For it cannot but be of great fervice to a painter to be well acquainted with the nature of what he is to imitate, and of thofe colours with which he is to give life and perfedion to his de- figns; not to fpeak of the pleafure there is in being able to account truly and folidly for the various eflfeds and appearances of light. From a due tempering, for ex¬ ample, and degrading, of the tints in a pidure; from making colours partake of each other, according to the refledion of light from one objed to another; there arifes, in fome meafure, that fublime harmony which may be confidered as the true mufic of the eye. And this harmony has its foundation in the genuine priii’ ciples of optics. Now this could not happen in the fyftem of thofe philofophers, who held, that colours did not originally exift in light, but were, on the contra¬ ry, nothing elfe than fo many modifications which it un¬ derwent in refleding from or paffing through other fubftances; thus fubjed to alterations without end, and every moment liable to perilh. Were that the cafe, bodies could no more receive any hues one from ano¬ ther, nor this body partake of the colourof that, than fcarlet, for example, becaufe it has the power of chan¬ ging into red all the rays of the fun or Iky which im¬ mediately fall upon it, has the power of changing into red all the other rays refleded to it from a blue or any other colour in its neighbourhood. Whereas, allowing that colours are in their own nature immutable one in¬ to another, and that every body rtfleds more or lefs every fort of coloured rays, though thofe rays in the greateft number which are of the colour it exhibits, there muft neceffarily arife, in colours placed near one another, certain particular hues or temperaments of co¬ lour; nay, this influence of one colour upon another may be fofar traced, that three or four bodies of dif¬ ferent colours, and likewife the intenfenefs of the light falling upon each, being affigned, we may eafily deter¬ mine in what fituations, end how much, they would tinge each other. We may thus, too, by the fame ' principle of optics, account for feveral other things pradifed by painters ; infomuch that a perfon, who has carefully obferved natural effeds with an eye di- reded by folid learning, rtiall be able to form general rules, where another can only diftinguifh particular cafes. But after all, the pidures of the beft colourifls are, it 5806 Colouring, ,'t is untvcrfaHy allowed, the books in which a young painter muft chiefly look for the rules of colouring; that is, of that branch of painting which contributes fo much to exprefs the beauty of objeAs, and is fo requi- fite to reprefent them as what they really are. Gior- gone and Titian feem to have difcoveted circumftances in nature, which others have entirely overlooked ; and the lad in particular has been happy enough to exprefs them with a pencil as delicate as his eye was quick and piercing. In his works we behold that fweetnefs of colouring which is produced by union ; that beauty which is confident with truth ; and all the infenfible tranfmutations, all the foft tranfitions, in a word, all the plealing modulations, of tints and colours. When a young painter has, by clofe application, acquired frctn Titian, whom he can never fufBciently dwell up¬ on, that art which, of all painters, hehasbeft contri¬ ved to hide, he would do well to turn to Baffano and Paolo, on account of the beauty, boldnefs, and ele¬ gance of their touches. That richnefs, foftnefs, and frefhnefs of colouring, for which the Lombard fchool is fo juftly cried up, may likewife be of great ferviee to him. Nor will he reap lefs benefit by (ludying the principles and praflice of the Flemifh fchool ; which, chiefly by means of her varniflies, has contrived to give a moil enchanting luftre and tranfparency to her co¬ lours. But whatever pi&ures a young painter may choofe to ftudy the art of colouring upon, he muft take great care that they are well preferved. There are very few pieces which have not fuffered more or lefs by the length, not to fay the injuries, of time ; and perhaps that precious patina, which years alone can impart to paintings, is in fome meafure akin to that other kind which ages alone impart to medals; inafmuch as, by giving teftimony to their antiquity, it renders them proportionably beautiful in the fuperftitious eyes of the learned. It muft indeed be allowed, that if, on the one hand, this patina beftows, as it really does, an extraordinary degree of harmony upon the colours of a pi&ure, and deftroys, or at leaft: greatly lefiens, their original rawnefs, it, on the other hand, equally im¬ pairs the frelhnefs and life of them. A piece feen ma¬ ny years after it has been painted, appears much as it would do, immediately after painting, behind a dull glafs. It is no idle opinion, that Paolo Veronefe, at¬ tentive above all things to the beauty of his colours, and what is called Jlrepito, left entirely to time the care of harmonizing them perfe&ly and (as we may fay) raellowing them. But. moft of the old mafters took that talk upon themfelves; and never expofed their works to the eyes of the public, until they had ripened and finilhed them with their own hands. And who can fay whether the C^rj^of Moneta, or the of Baffano, have been more improved or injured (if we may fo fpeak) by the touchings and retouchings of time, in the courfe of more than two centuries? It is indeed impoffible to be determined. But the ftudious pupil may make himfelf ample amends for any injuries which his originals may have received from the hands of time, by turning to truth, and to Nature which never grows old, but conftantly retains its primitive flower of youth, and was itfelf the model of the models before him. As fqon, therefore, as a young painter has laid a proper foundation for good colouring, by ftudying the bell Part I* mafters, he fhould turn all Ms thooghts to truth and Camera nature. And it would perhaps be well worth while to 0bfcura- have, in.the academies of painting, models for colour¬ ing as well as defigning ; that as from the one the pu¬ pils learn to give their due proportion to the feveral members and mufcles, they may learn from the other to make their carnations rich and warm, and faithfully copy the different local hues which appear quite dif- tinft in the different parts of a fine body. To iiluftrate ftill farther the ufe of fuch a model, let us fuppofe it placed in different lights ; now in that of the fun, now in that of the fky, and now again in that of a lamp or candle ; one time placed in the (hade, and another in a reflected light. Hence the pupil may learn all the different effedts of the completion in different circum¬ ftances, whether the livid, the lucid, or tranfparent ; and, above all, that variety of tints and half-tints, oc- cafioned in the colour of the Ikin by the epidermis ha¬ ving the bones immediately under it in fome places, and in others a greater or lefs number of blood-vtftels or quantity of fat. An artift who had long ftudied fuch a model, would run no rifle of degrading the beau¬ ties of nature by any particularity of ftyle, or of giving into that prepofterous fulnefs and floridnefs of colour which is at prefent fo much the tafte. He would not feed his figures with rofes, as an ancient painter of Greece fhrewdly expreffed it, but with good beef; a difference, which the learned eye of a modern writer could perceive between the colouring of Barocci and dial. j. that of Titian. To pra&ife in that manner, is, ac¬ cording to a great mailer, no better than inuring one’s felf to the commiffion of blunders. What ftatues are in defign, nature is in colouring; the fountain-head of that perfe&ion to which every artift, ambitious to ex¬ cel, (hould conftantly afpire: and accordingly the Flemifh painters, in confequence of their aiming fole- ly to copy nature, are in colouring as excellent as they are wont to be aukward in defigning. Sect. VI. Of the Camera Obfcura. 9. Wl may well imagine, that could a young pain¬ ter but view a pidlure by the hand of nature herfelf, and ttudy it at his leifure, he would profit more by it than by the moft excellent performances by the hand of man. Now, nature is continually forming fuch pic'- tures in eur eye. The rays of light coming from ex¬ terior objeds, after entering the pupil pafs through the cryftalline humour; and, being there refraded in confe¬ quence of the lenticular form of that part, proceed to the retina, which lies at the bottom of the eye, and ftamp up it, by their union, the image of the objed towards which the pupil is direded. The confeqnencfe of which is, that the foul, by means as yet unknown to us, receives immediate intelligence of thefe rays, and comes to fee the objeds that fent them. But this grand operation of nature, the difeovery of which was refer- ved for our times, might have remained an idle amufe- ment of phyfical curiofity, without being of the leaft fervice to the painter, had not means been happily found of imitating it. The machine contrived for this pnr- pofe, confifts of a lens and mirrror fo fituated, that the fecond throws the-pidure of any thing properly expo- pofed to the firft, and that too of a competent large- refs, on a clean ftieet of paper, where it may be feen and contemplated at leifure. PAINTING. Part I Camera Obfcura. PAIN As tliis artificial eye, ufually called a camera optica or obfcura, gives no admittance to any rays of light, but tbofe coming from the thing whofe reprefentation is wanted, there refuits from them a pidure of inex- preffible force and brightnefs; and as nothnig is more delightful to behold, fo nothing can be more ufeful to ftudy, than fuch a pidure. For, not to fpeak of the juftnefs of the contours, the exadnefs of the perfpedive and of the chiarofcura, which exceeds conception ; the colours are of a vivacity and richnefs that nothing can excel ; the parts which ftand out moft, and are mod expofed to the light^^ppear furprifingly loofe and re- fplendent; and this loofenefs and refplendency declines gradually, as the parts themfelves fink in, or retire from the light. The fliades are ftrong without harfhnefs, and the contours precife without being (harp. Where- ever any refleded light falls, there appears, in confe- quence of it, an infinite variety of tints, which, with¬ out this contrivance, it would be imppffible'to difcern. Yet there prevails fuch a harmony amongft all the co¬ lours of the piece, that fcarce any one of them can be faid to clalh with another. After all, it is no way furprifing, that we fhould, by means of this contrivance, difcover; what otherwife we might juftly defpair of ever being acquainted with. We cannot look diredly at any objed that is not fur- rounded by fo many others, all darting their rays to¬ gether into our eyes, that it is. impoffible we Ihould di- llinguifli all the different modulations of its light and colours. At lead we can only fee them in fo dull and confufed a manner, as not to be able to determine any thing precifely about them. Whereas, in the camera obfcura, the vifual faculty is brought wholly to bear upon the objed before it; and the light of every other objed is, as it were, perfedly extinguifhed. Another mod adonifhing perfedion in pidures of this kind is, the diminution of the fize, and of the in- tenfenefs of light and colour, of the objeds and all their parts, in proportion to their didance from the eye. At a greater didance, the colours appear more faint, and the contours more obfcure. The fhades, likewife, are a great deal weaker in a lefs or more remote light. On the other hand, thofe objeds, which are larged in themfelves, or lie neared to the eye, have the mpd ex- ad contours, the dronged fhades, and the brighted co¬ lours: all which qualities are requifite to form that kind of perfpedive which is called aerial; as though the air between the eye and external objeds, not only veiled them a little, but in fome fort gnawed and prey¬ ed upon them. This kind of perfpedive conditutes a principal part of that branch of painting, which regards the forefhortening of-figures, and likewife the bring¬ ing them forward, and throwing them back in fuch a manner as to make us lofe fight of the ground upon which they are drawn. It is, in a word, this kind of per¬ fpedive, from which, affided by linear perfpedive, arife Dolco cofe a vedere, e dolci inganni ; “ Things fweet to fee, and fweet deceptions.” Nothing proves this better than the camera obfcura, in which nature paints the objeds which lie near the eye, as it were, with a hard and (harp pencil, and thofe at a didance with a foft and blunt one. The bed modern painters among the Italians have availed themfelves greatly of this contrivance; nor is it pofiible they fhould have otherwife reprefented things Vol. VIII. i TING. fo much to the life. It is probable, too, that feveral of the Tramontane maders, confidering their fuccefs in expreffing the minuted objeds, have done the fame. Every one knows of what fervice it has been to Spag- noletto of Bologna, fome of whofe pidures have a grand and mod wonderful tffed. We once happened to be prefent where a very able mader was fhewn this machine for the fird time. „ It is impoffible to exprefs the pleafure he took in examining it. The more he confidered it, the more he feemed to be charmed with it. In fhort, after trying it a thoufand different ways, and with a tboufand different models, he candidly con- fcfTtd, that nothing could compare with the pidures of fo excellent and inimitable a mader. Another, no lefs eminent, has given it as his opinion, that an academy, with no other furniture than the book of da Vinci, a critical account of the excellencies of the capital pain¬ ters, the cads of the fined Greek datues, and the pic¬ tures of the camera obfcura, would alone be fufficient to revive the art of painting. Let the young painter, therefore, begin as early as poffible to dudy thefe di¬ vine pidures, and dudy them all the days of his life, for he never will be able fufficiently to contemplate them. In fhort, painters fhould make the fame ufe of the camera obfcura which naturalids and adronomers make of the microfcope and telefcope; for all thefe in- druments equally contribute to make known and re- prefent nature. Sect. VII. Of Drapery. 10. Drapery is one of the mod important branches of the whole art, and accordingly demands the greatefl attention and dudy. It feldom happens that a painter has nothing but naked figures to reprefent ; nay, his fubjeds generally confid of figures clothed from head to foot. Now the flowing of the folds in every gar¬ ment depends chiefly upon the relief of the parts that lie under it. A certain author, we forget his name, obferves, that as the inequalities of a furface are dif- coverable by the inequalities in the water that runs over it, fo the poflure and fhape of the members mud be difcernible by the folds of the garment that covers them. Thofe idle windings and gatherings, with which fome painters have affeded to cover their figures, make the clothes made up of them look as if the body had fled from tinder them, and left nothing in its place but a heap of empty bubbles, fit emblems of the brain that conceived them. As from the trunk of a tree there iffue here and there boughs of various forms, fo from one midrefs-fold there always flow many lefler ones : and as it is on the quality of the tree that the elegance, compadnefs, or opennefs of its branches chiefly depends ; it is, in like manner, by the quality of the fluff of which a garment is made, that the num¬ ber, order, and fize of its folds mud be determined. To fum up all in two words; the drapery ought to be natural and eafy, fo as to (how what duff it is, and what parts it covers. It ought, as a certain author expreffes it, to cover the body, as it were merely to (how it. It was formerly the cudom with fome of our maders to draw all their figures naked, and then drape them; from the fame principle that they fird drew the fleele- tons of their figures, and afterwards covered them w-ith mufcles. And it was by proceeding in this manner that they attained to fiicli a degree of truth in expref* 32 T ling 5S07 Of Drapery. jSoS PAIN Of fing the folds of their drapery, and the joints and di- Landfcape. redtion of the principal members that lay under it, fo as to exhibit in a molt ftriking manner, the attitude of the perfon to whom they belonged. That the ancient fculptors clothed their ftatues with equal truth and grace, appears from many of them that are ftill in be- ing; particularly a Flora lately dug up in Rome, whofe drapery is executed with fo much judgment, and in fo grand and rich a ftyle, that it may vie with the fineft of their naked ftatues, even with the Venus of Medicis. The ftatue's of the ancients had fo much beauty when naked, that they retained a great deal when clothed. But here it mull be confidered, that it was ufual with them to fuppofe their originals clothed with wet gar¬ ments, and of an extreme finenefs and delicacy, that, by lying clofe to the parts,, and in a manner clinging to them, they might the better fhow what thefe parts were. For this reafon a painter is not to confine him- felf to the ftudy of the ancient ftatues, left he (hould contra& a dry ftyle, and even fall into the fame faults with fome great matters who, accuftomed to drape with fuch light fluffs as fit clofe to the body, have after¬ wards made the coarfeft lie in the fame manner, fo as plainly to exhibit the mufcles underneath them. It is therefore proper to ftudy nature herfelf, and thofe mo¬ dern mailers who have come neareft to her in this branch ; fuch as Paolo Veronefe, Andrea del Sarto, Rubens, and above all, Guido Reni. The flow of their drapery is foft and gentle; and the gatherings and plaits are fo contrived, as not only not to hide the body, but to add grace and dignity to it. Their gold, filk, and woollen fluffs, are fo diftinguifhable one from another, by the quality of their feveral luftres, and the peculiar light and fhade belonging to each, but above all by the form and flow of their folds, that the age and fex of their figures are hardly more difcoverable by their faces. Albert Durer is another great matter in this branch, infomuch that Guido himfelf was not alhamed to ftudy him. There are fttH extant feveral drawings made with the pen by this great man, in which he has copied whole figures from Albert, and fcrupuloufly retained the flow of his drapery as far as his own peculiar ftyle, lefs harfh and fharp, but more eafy and graceful, would allow. It may be faid that he made the fame ufc of Albert, that our modern wri¬ ters ought to make of the beft authors of the 13th cen¬ tury. S£ct. VIII. Of Landfcape and Architecture. 11. When our young painter has made a fufficient progrefs in thofe principal branches of his art, the de- figning, perfpeftive, colouring, and drapery of human figures, he fhould turn his thoughts to landfcape and architefture : for, by ftudying them, he will render himfelf univerfal, and qualified to undertake any fub- jeft 5 fo as not to refemble certain literati, who, tho’ great matters in fome articles, are mere children in every thing elfe. The moft eminent landfcape painters are Pouffin, Lorenefe, and Titian. Pouflin was remarkable for his great diligence. His pieces are quite exotic and uncommon ; being fet off with buildings in a beautiful but Angular ftyle ; and with learned epifodes, fuch as poets reciting their verfes to the woods, and youths exencifing themfdves in the TING. Part L feveral gymnaftic games of antiquity 5 by which it Architec. plainly appears, that be was more indebted for his fub-111 lc- jefts to the deferiptions of Paufanias, than to nature and truth. Lorenefe applied himfelf chiefly to exprefs the va¬ rious phenomena of light, efpecially thofe perceivable in the heavens. And, thanks to the happy climate of Rome, where he ftudied and exercifed his talents, he has left us the brighteft flties, and the richeft and moft glorioufly cloud-tipt horizons that can be well concei¬ ved. Nay, the fun himfelf, which, like the Almighty, can be reprefented merely by his effedls, has fcarce efcaped his daring and ambitious pencil. Titian, the great confident of nature, is the Homer of landfcape. His feenes have fo much truth, fo much variety, and fuch a bloom in them, that it is impoffible to behold them, without wilhing, as if they were real, to make an excurfion into them. And perhaps the, fineft landfcape that ever iffued from mortal hands, is the back ground of his Martyrdom of St Peter; where by the difference between the bodies and the leaves of his trees, and the difpofition of their branches, one im¬ mediately difeovers the difference between the trees themfelves; where the different foils are fo well expref- fed, and fo exquifitely clothed with their proper plants, that a botanift has much ado to keep his hands from them. See Part II. Se open a way to the army of the Ifraelites f Nor has he difplayed lefs judgment in reviving, in his defigns en¬ graved by Agoftino of Venice, the little loves of Ae- tius, playing with the arms of Alexander, conquered by the beauty of Roxana. Among the ancients, Apelles and Parrhafius were thofe who diftinguilhed themfelvs molt in allegorical fubjeds, in which the inventive faculty fiiows itfelf to the greateft advantage ; the firft by his pidure off SeeLucum Calumny f , the fecond by that of the Genius of the}'!5011 Ca- Athenians*. The ancient painter called Galaton, gave cTrlo 'iha'^ likewife a fine proof of his genius in this branch, by in the Life reprefenting a great number of poets greedily quench- ing their third in the waters guftiing from the mouth ^ott ^°; of the fublime Homer. And to this allegory, ac- Hiji1 cording to Guigni, Pliny J has an eye, wjien he calls Ht. xxxv.* that prince of poets, the fountain of wits. But it is,c. 10. after all, no way furprifing that we ftiould often t lib. meet fuch fine flights of fancy in the ancient artifts.xv"'c‘tp'5- They were not guided in their works by a blind prac¬ tice : they were men of polite education ; converfant TfM, with the letters of the age in which they lived; and the companions, rather than the fervants, of the great suea PAINTING. 5812 PAIN Pifpofition. men who employed them. The fineft allegorical ~~~ : painter among the moderns was Rubens ; and he was, accordingly, much celebrated for it. The belt critics, however, find fault with his uniting in Luxemburg dial's Kallery> t^e queen-mother, in council, with two car- 13 ‘ 1 * dinals and Mercury. Nor is there lefs impropriety in his making Tritons and Nereids, in another piece of the fame gallery, fwim to the queen’s veffel through the galleys of the knights of St Stephen. Such freedoms are equally difguftful with the prophecies of Sannazaro’s Proteus, concerning the myftery of the incarnation; or the Indian kings of Camoens, reafon- ing with the Portuguefe on the adventures of Ulyffes. The heft modern performances in pi&urefque alle¬ gory are, certainly, thofe of Poufiin ; who availed himfelf, with great diferetion and judgment, of the raft treafures with which, by a clofe ftudy of the ancients, he had enriched his memory. On the other hand, le Brim, his countryman, has been very un¬ happy this way. Ambitious to have every thing his own, inftead of allegories, he has filled the gallery of Verfatlles with enigmas and riddles, of which none but himfetf was qualified to be the Oedipus. Allegory muft be ingenious, it is true ; but then it muft be equally perfpicuous ; for which reafon, a painter fbould avoid all vague and indeterminate allufions, and like- wife thofe to hiftory and heathen mythology which are too abftrufe to be underftood by the generally of fpedfatos. The befl way, perhaps, to fymbolize moral and abftraft things, is to reprefent particu- SeeBelhri'sfar events: as Caracci did, by advice of Monfig- Life ofCa- nore Agucchi, in the Farnefian palace. For example, what can better exprefs a hero’s love towards his country, than the virtuous Decius confecrating him¬ felf boldly to the infernal gods, in order to fecure viftory to his countrymen over their enemies ? What finer emblems can we defire, of emulation, and an in- fatiable thirft for glory, than Julius Caefar weeping before the ftatue of Alexander in the temple of Her¬ cules at Gades ? of the inconftancy of fortune, than Marius fitting on the ruins of Carthage, and receiving, inftead of the acclamations of an army joyfully fain¬ ting him imperator, orders from a ii&or of Sextilius to quit Africa ? of indiferetion, than Candaules, who, by flrewing the naked beauties of his wife to his friend Giges, kindled a paffion that faon made him repent his folly ? Such reprefentations as thefe require no comment ; they carry their explanation along with them. Befides, fuppofing, and it is the worft we can fuppofe, that the painter’s aim in them fhould happen not to be underftood, his piece would ftill give de¬ light. It is thus that the fables of Ariofto prove fo entertaining, even to thofe who underftand nothing of the moral couched under them ; and likewife the ^ineis, though all do not comprehend the allufions and double intent of the poet. Sect. XI. Of Difpofttion. 14. So much for invention. Difpofition, which may be confidered as a branch of invention, confifts in the proper ftationing of what the inventive faculty has imagined, fo as to exprefs the fubjeft in the mod lively manner. The chief merit of difpofition may be faid to confift in that diforder, which, wearing the ap¬ pearance of mere chance, is, in faft, the moft ftudied TING. Part I. effeft of art. A painter, therefore, is equally to Dhpofition avoid the drynefs of thofe ancients who always plant¬ ed their figures like fo many couples in a procefiion, and the affe&ation of thofe moderns who jumble them together as if they were met merely to fight and fquabble. In this branch Raphael was happy enough tochoofe the juft medium, and attain perfec¬ tion. The difpofition of his figures is alway exactly fuch as the fubjett requires. In the Battle of Con' Jlantine, they are confufedly cluttered with as much art, as they are regularly marlhalled in Chrijl's com- viittnent of the keys to St Peter and conftituting him prince of the apoftles. Let the inferior figures of a piece be placed as they will, the principal figure fhould ftrike the eye moft, and ftand out, as it were, from among the reft. This may be effe&ed various ways, as by placing it on the foremoft lines, or in foroe other confpicuous part of the piece ; by exhibiting it, in a manner, by itfelf; by making the principal light fall upon it ; by giving it the moft refplendent drapery ; or, indeed, by feveral of thefe methods, nay, by all of them together. For, being the hero of the pi&urefque fable, it is but juft that it fhould draw the eye to itfelf, and lord it, as it were, over all the other obje&s. According to Leon Batifta Alberti, painters fhould follow the example of comic writers, who compofe fheir fable of as few perfons as pofiible. For, in faft, a crowded pifture is apt to give as much pain to the fpe&ator, as a crowded road to the traveller. Some fubjedfts, it muft be granted, require a num¬ ber, nay, a nation, as it were, of figures. On thefe occafions, it depends entirely on the fkill of the paint¬ er to difpofe of them in fuch a manner, that the prin¬ cipal ones may always make the principal appearance; and contrive matters fo, that the piece be not over¬ crowded, dr want convenient refts and paufes. He muft, in a word, take care that his piece be full, but not charged. In this refpetft, the Battles of Alexan¬ der by Le Brun are mafter-pieees which can never be fufficiently ftudied ; whereas nothing, on the other hand, can be more unhappy than the famous Paradife of Tintoret, which covers one entire fide of the great council-chamber at Venice. It appears no better than a confufed heap of figures, a fwarm, a cloud, a chaos, which pains and fatigues the eye. What a pity it is that he did not difpofe this fubjeifl after a model of his own, now in the gallery ofBevilacqita at Verona! In this laft, the feveral choirs of martyrs, virgins, bi- fhops, and other faints, are judicioufly thrown into fo many clufters, parted here and there by a fine fleece of clouds; fo as to exhibit the innumerable hoft of hea¬ ven drawn up in a way that makes a moft agreeable and glorious appearance. There goes a ftory, to our purpofe, of a celebrated mafter, who in a drawing of the Uuiverfal Deluge, the better to exprefs the im- menfity of the waters that covered the earth, left a corner of his paper without figures. Being allied, if he did not intend to fill it up : No, faid he ; do not you fee that my leaving it empty is what precifely conftitutes the picture ? The reafon for breaking a compofition into feveral groupes is, that the eye, palling freely from one object to another, may the better comprehend the whole. But the painter is not to ftop here; for thefe groupes are, Part. I. PAIN Difpofition are, befidw, to be fo art Ml y put together, as to form _ rich chillers, give the whole compofition a Angular air of grandeur, and afford the fpeflator an opportunity of difceming the piece at a diftance, and taking the whole in, as it were, at a Angle glance. Thefe effe&s are greatly promoted by a due regard to the nature of colours, fo as not to place together thofe which are apt to pain by their oppoAtion, or diilraft by their variety. They fhould be fo judicioufly difpofed as to temper and qualify each other. A proper ufe of the chiarofcuro is likevvife of great fervice on this occalion, The grotipes are eafsly part¬ ed, and the whole pi&ure acquires a grand effedf, by introducing fome ftrong falls of (hade, and, above all, one principal beam of light. This method has been followed with great fuccefs by Rembrant in a famous pifture of his, reprefenting the Virgin at the foot of the crofs on mount Calvary; the principal light dart¬ ing upon her through a break of the clouds, while the reft of the Agures about her Hand more or lefs in the {hade. Tintoret, too, acquired great reputation, as well by that brifknefs with which he enlivened his fi¬ gures, as by his mafteriy manner of Ihading them j and Polidoro de Caravaggio, though he fcarce paint¬ ed any thing but balfo-relievos, was particularly fa¬ mous for introducing with great (kill the effeds of the cbiarofcuro, a thing Arft attempted by Mantegna in his Trinmph of Julius Cafar. It is by this means that his compofitions appear fo ftrikingly divided into different groupes, and, among their other perfedions, afford fo much delight thro’the beautiful difpoAtion that reigns in them. In like manner, a painter, by the help of perfpec- tive, efpecially that called teriaf, the oppofition of lo¬ cal Colours, and other oontrivanees which he may ex- ped to hit upon by ftodying nature, and thofe who have beft ftudied her before him, will be able not only to part his groupes, but make them appear at different diltances, fo as to leave fufficient paffages between them. But the greateft caution is to be ufed in the purfuit of the methods here laid down ; efpecially in the ma¬ nagement of the chiarofcuro, that the effeds attribu¬ ted to light and ffiade, and to their various concomi¬ tants, may not run Counter to truth and experience-. This a capital point. For this purpofe, a painter would do well to make, in little 'figures, as Tintoret and Pooffin ufed to do, a model of the fubjed that he intends to reprefent, and then illuminate it by lamp or candle light. By this means he may come to know with certainty, if the chiarofcuro, which he has form¬ ed in his mind, does not clafh with thereafon of things. By varying the height and diredion of-his light, he may eafily difcover fuch accidental effeds as are moft likely to recommend his performance, and fo eftablifli a proper fyftem for the illuminating it. Nor will he afterwards find it a difficult matter to modify the qua¬ lity of his fliades, by foftening or ftrengthening them, according to the fituation of his fcene, and the quality of the light falling upon it. If it (hould happen to be a candle or lamp light fcene, he would then have no¬ thing to do but confider his model well, and faithfully copy it. In the next-place, to turn a groupe elegantly, the beft pattern is that of a bunch of grapes adopted by Titian. As, of the many grains that compofe a bunch TING. 5813 of grapes, fome are ftruck diredly by the light, andDifpofuton. thofe oppofite to them are in the /hade, whilft the in- termediate ones partake of both light and (hade in a greater or lefs degree ; fo, according to Titian, the figures of a groupe (hould be fo difpofed, that, by the union of the chiarofcuro, feveral things may appear as it were but one thing. And in fad it is only from his having purfued this method, that we can account for the very grand effed of his pieces this way, in which it is impoffible to ftudy him too much. The manneriils, who do not follow nature in the track of the mailers juft mentioned, are apt to commit many faults. The reafon of their figures cafting their (hades in this or that manner feldom appears in the pidure, or at lead does not appear Efficiently pro¬ bable. They are, befides, wont to trefpafs all bounds in fplaffiing their pieces with light, that is, in enliven¬ ing thofe parts which we ufually term the deafs of a pidure. This method, no doubt, has fometimes a very fine effeft ; but it is, hovvevet, to be ufed with no fmall difcretion, as otherwife the whole lofes that union, that paufe, that majeftic filence, as Caracci ufed to call it, which affords fo much pleafure. The eye is not lefs hurt by many lights fcattered here and Hogarth'} there over a pidure, than the ear is by the confufed'^"'’^ °f tioife of different perfons fpeaking all together in an af- eauJ~ fembly. Guido Reni, whohas imparted to his paintings that gaiety and fplendour in which he lived, feems ena¬ moured with a bright and open light; whereas Michael Angelo da Caravaggio, who was of a fullen and favage difpofition, appears fondeft of a gloomy and clouded Iky : fo that neither of them were qualified to handle indifferently all fubjeds. The chiraofcuro may like- wife prove of great fervice to a painter in giving his compofition a grand effed ; but, neverthelefs, the light he choofes muft be adapted to the fituation of the fcene where the adion is laid: nor would he be lefs faulty, who in a grotto or cavern, where the light entered by a chink, ffiould make his (hades foft and tender, than ■him who (hould reprefent them ftrong and bold in an open (Icy-light. But this is not, by many, the only fault which man- nerifts are apt to be guiky of in hiftorical pieces, and particularly in the difpofition of their figures. To fay nothing of their favourite grotipe of a woman lying on the ground with one child at her bread, and another playing about her, and the like, which they generally place on the fir ft lines of their pieces; nor of thofe half¬ figures in the back ground peeping out from the hol¬ lows contrived for them : they make a common prac¬ tice of mixing naked with clothed figures; old men with young ; placing one figure with its face towards you, and another with its back; they contrail violent motions with languid attitudes, and teem to aim at oppofition in every thing ; whereas oppofitions never pleafe, but when they arife naturally from the fubjed, like antithefes in a difeourfe. As to foreftiortened figures, too much affedation In ufrng or-avoiding them is equally blameable. The at¬ titudes had better be compofed than otherwife. It ve¬ ry feldom happens that there is any occafion for ma¬ king them fo impetuous as to be in danger of iofing their equilibrium ; a thing too much pradifed by fome painters. 5814 PAIN Exfireflion ln regard to drapery, equal care fliould be taken to Pafllons avo‘^ l^at poverty, which makes fome mailers look as 1_ if, through mere penury, they grudged clothes to their figures ; and that profuiion which Albani imputed to Guido, faying, that he was rather a tailor than a painter. The ornaments of drefs (liould be ufed with great fobriety ; and it will not be amifs to remember what was once faid to an ancient painter : “ I pity you greatly ; unable to make Helen handfome, you have taken care to make her fine.” Let the whole, in a word, and all the different parts of the difpofition, poflefs probability, grace, coftume, and the particular charafter of what is to be reprefent- ed. Let nothing look like uniformity ofmanner ; which does not appear lefs in the compofition than it does in colouring, drapery, and defign ; and is, as it were, that kind of accent, by which painters may be as rea¬ dily diltinguifhed as foreigners are, by pronouncing in the fame manner all the different languages they happen to be acquainted with. Sect. XII. Of the Exprejfon of the Pajfions. 15. That language which above all others a painter fhould carefully endeavour to learn, and from nature herfelf, is the language of the pafiions. Without it the fineft works muft appear lifelefs and inanimate. It is not enough for a painter to be able to delineate the moil equifite forms, give them the mod graceful atti¬ tudes, and compofe them well together; it is not e- nough to drefs them.out with propriety, and in the mod beautiful colours; it is not enough, in fine, by the powerful magic of light and fhade to make the canva’s vanifh. No; he mud likewife know how to clothe his figures with grief, with joy, with fear, with anger ; he muft, in fome fort, write on their faces what they think and what they feel; he muft give them life and fpeech. It is indeed in this branch that painting tru¬ ly foars, and in a manner rifes fuperior to itfelf ; it is in this branch die makes the fpedtator apprehend much more than what (he expreffes, The means employed in her imitations by painting, are the circumfcription of terms, the chiraofcuro, and colours; all which appear folely calculated to ftrike the vifual faculty. Notwithftanding which, fhe contrives to reprefent hard and foft, rough and fmooth furfaces, which are obje&s of the touch ; and this by means of certain tints, and a certain chi^rofcuro, which has a different look in marble, in the bark of trees, in downy and delicate fubftances. Nay, fhe contrives to exprefs found and motion, by means of light and fhade, and certain particular configurations. In fome land- fcapes of Diderich, we almod hear the water murmur, and fee it tremble along the fides of the river, and of the boats upon it. In the Battle of Burgogne we are really apt to fancy that the trumpet founds ; 'and we fee the horfe, who has thrown his rider, fcamper along the plain. But what is fttll more wonderful, painting, in virtue of her various colours and certain particular geftures, expreffes even the fentiments and mod hidden affe&ions of the foul, and renders her vifible, fo as to make the eye not only touch and hear, but even kindle into paflion, and reafon. Many have written, and amongft the reft the fa¬ mous le Brun, on the various changes, that, according to the various pafiions, happen in the mufcles of the TING. Part I. face, which is, as it were, the dumb tongue of the foul. Expreffion They obferve, for example, that in fits of anger, the p°f,.the face reddens, the mufcles of the lips puff out, the eyes . a °ns' fparkle ; and that, on the contrary, in fits of melan¬ choly, the eyes grow motionlefs and dead, the face pale, and the lips fink in. It may be of fervice to a painter to read thefe and fuch other remarks ; but it will be of infinitely more fervice to ftudy them in na¬ ture itfelf, from which they have been borrowed, and which exhibits them in that lively manner which nei¬ ther tongue nor pen can exprefs. But if a painter is to have immediate recourfe to na¬ ture in any thing, it is particularly in treating thofe very minute and almoft imperceptible differences, by which, however, things very different from each other are often expreffed. This is particularly the cafe with regard to the pafiions of laughing and crying ; as in thefe, however contrary, the roufcles of the face ope¬ rate nearly in the fame manner. As the famous Pietro de Cortona was one day finifhing the face of a crying child in a reprefentation of the Iron Age, with which he was adorning the floor, called the Hot bath, in the royal palace of Pitti, Ferdinand II. who happened lo be looking over him for his amufement, could not for- '* > bear exprefiing his approbation, by crying out, “Oh how well that child cries !” To whom the artift,—- , ■ “ Has your majefty a mind to fee how eafy it is to ; make children laugh ? Behold, I’ll prove it in an iji- ftantAnd taking up his pencil, by giving the con¬ tour of the mouth a concave turn downwards, inftead of the convex upwards which it before had, and with little or no alteration in any other part of the face, he made the child, who a little before feemed ready to burft its heart with crying, appear in equal danger ci burfting its fides with immoderate laughter ; and then, by reftoring the altered features to their former pofx- tion, he foon fet the child a-crying again. [Leftiibe*, s of Philip Baldinucci, in the academy of la Crufca it '* Lyftrato, &c.J According to Leonardo da Vinci, the bed mafters that a painter can have recourfe to in this branch, are thofe dumb men, who have found out the method of exprefling their fentiments by the motion of their hands, eyes, eyebrows, and in fliort every other part of the body. This advice, no doubt, is very good ; but then fuch geftures muft be imitated with great fobriety and moderation; left they fhould appear too ftrong and ex- aggerated, and the piece fhould fhow nothing put pan¬ tomimes, when fpeaking figures alone are to be exhi¬ bited ; and fo become theatrical and fecond-hand, or, at heft, look like the copy of a theatrical and fecond- hand nature. We are told ftrange things of the ancient, painters of Greece in regard to expreflion : efpecially of Anili¬ des ; who, in a piSure of his, reprefenting a woman wounded to death at a fiege, with a child crawling to her breall, makes her appear afraid, left the child, when fhe was dead, fhould, for want of milk, fuck her blood. A Medea murdering her children^ by Timo- machus, was likewife much cried up, as the ingenious artift contrived to exprefs, at once, in her coumenance, both the fury that hurried her on to the commiflion of fo great a crime, and the tendernefs of a mother that feemed to withhold her from it. Rubens attejppttd to exprefs fuch a double effed in the face of jjjdary of Me- Parti. PAIN Expreffiou dicis, ftill in pain from her pad labour, and at the fame ' of the (;me ful] 0f jQy at the birth of a Dauphin. And in Pafl*01is' the countenance of Sanda Polonia, painted by Tie- polo for St Anthony’s church at Padua, one may clearly read a mixture of pain from the wound given her by the executioner, and of pleafure from the pro* fped of paradife opened to her by it. Few, to fay the truth, are the examples of (Irong expreflion afforded by the Venetian, Flemifh, or Lom- b'rd fchools. Deprived of that great happinefs, the happinefs of being able to contemplate, at leifure, the works of the ancients, th^ purefl fources of perfe&ion in point of defign, exprefiion, and charaffer ; and ha¬ ving nothing but nature condantly before their eyes ; they made ilrength of colouring, blooming complec- tions, and the grand effeds of the chiarofcuro, their principal ftudy : they aimed more at charming the fen- fes than at captivating the underftanding. The Ve¬ netians, in particular, feem to have placed their whole glory in fetting off their pieces with all th&t rich va¬ riety of perfonages and drefs, which their capital is continually receiving by means of its extenfive com¬ merce, and which attrads fo much the eyes of allthofe who vifit it. It is much to be doubted, if; in all the pidures of Paolo Veronefe, there is to be found a bold and judicious expreffion, or one of thofe attitudes which, as Petrarch exprefles it, fpeak without words; unlefs, perhaps, it be that remarkable one in his Marriage Feaji of Cana of Galilee. At one end of of the table, and diredly oppoiite to the bridegroom, whofe eyes are fixed upon her, there appears a woman in red, holding up to him the ilcirt of her garment; as much as to fay, we may fuppofe, that the wine miraculoufly oduced was exadly of thecolour with the fluff on her back. And in fad it is red wine we fee in the cups and pitchers. But all this while the faces and attitudes of mod of the company betray not the lead fign of .wonder at fo extraordinary a miracle. They all, in a manner, appear intent upon nothing but eating, drink¬ ing, and making merry. Such, in general, is the ftyle of the Venetian fchool. The Florentine, over which Michael Angelo prefided, above all things curious of defign, was moft minutely and fcrupuloufly exadt in point of anatomy.

Here it was that Domenichino and Poufiin, both great maders of expreffion, refined themfelves, as appears more particularly by the St^e- rome of the one, and the Death of Germanicus, or the daughter of the Innocents, by the other. Here it was that arofe Raphael, the fovereign mader of them all. One would imagine, that pictures, which are ge¬ nerally confidered as the books of the ignorant, and of the ignorant only, he had undertaken to make the in- ftrudlors even of the learned. One would imagine, that * InJHu he intended, in fome meafure, to judify Quintilian *, I'b-XI- who affirms, that painting has more power over us caP' 3- than all the arts of rhetoric.

One of the boys, recol- le&ing within himfelf, keeps back, with all the ap¬ pearance of profound attention to the reafoning of the mader ; another, by the brifknefs of his attitude, dif- covers a greater quicknefs of apprehenfion ; while the third, who has already feized the conclufion, is endea¬ vouring to beat it into the fourth, who, danding mo- tionlefs, with open arms, a daring countenance, and an unfpcakable air of dupidity in his looks, will never perhaps be able to make any thing of the matter. And it is probably from this verygroupe that Albani, who dudied Raphael fo clofely, drew the following precept of his : “ That it behoves a painter to exprefs more circumdances than one by every attitude; and fo to employ his figures, that, by barely feeing what they are a&ually about, one maybe able toguefs, both what they have been already doing, and are next going to do.” This is indeed a difficult precept; but it is only by a due obfervance of it that the eye and the mind can be made to hang in fufpence on a painted piece of canvas. It is expreffion that a painter, ambitious to foar in his profeffion, mud, above all things, labour to perfeft himfelf in. It is the lad goal of his art, as "Xenoph. Socrates proves to Parrhafius. It is in expreffion that.Jw.f.m5rrt^' dumb poetry confids, and what the prince of our poets ' m* calls a vifible language. Sect. XI. Of proper Books for a Painter. From what has been already faid, it may be eafily gathered, that a painter fhould be neither illiterate, nor unprovided with books. Many are apt to imagine, that the Iconologia of Ripa, or fome fuch colleAion, is alone fufficient for this purpofe ; and that all the ap¬ paratus he dands in need of, may be reduced to a few cads of the remains of antiquity, or rather to what rem- brants ufed to call his antiques, being nothing more than coats of mail, turbants, {herds of duff, and all manner of old houfehold trumpery and wearing appa¬ rel. Such things, no doubt, are neceffary to a paint¬ er, and, perhaps, enough for one who wants only to paint half-lengths, oris willing to confine himfelf to a few low fubjefils. But they are by no means fufficient for him who would foar higher; for a painter who would attempt tiie Univerfe, and reprefent it in all its Algarotti on parts, fuch as it would appear, had not matter proved refradlory to the intentions of the fovereign Artid. Such a painter alone is a true, an univerfal, a perfedt painter. No mortal, indeed, mud ever expedt to rife to that fublimity ; yet all fhould afpire to it, on pain of ever continuing at a very mortifying didancc from it: as the orator, who wilhes to make a figure in his profeffion, fhould propofe to himfelf no lefs a pat- tern than that perfedt orator deferibed by Tully ; nor the courtier, than that perfedl courtier delineated by Cadiglione. It cannot, therefore, appear furprifing if we infid on the propriety of reckoning a good col- ,3 z U ledtioa 5816 Books for ale&Ion of books as part of fqch a painter’s implements. Painter. rj'(ie B;b]e, the Greek and Roman hiftorians, the works of Homer, that prince of painters, and of Virgil, are the moft claffical. To thefe let him add the Metamor- phofes of Ovid, fome of our belt poets, the voy¬ age of Paufanias, Vinci, Vafari, and others upon painting. It will alfo be of confiderable advantage to him to have a well-chofen colle&ion of drawings by the belt mafters, in order to trace the progrefs and hiftory of his art, and make himfelf acquainted with the various ftyles of painting, which have been, and now are, in the greateft vogue. The prince of the Roman fchool was not afhamed to hang up in his ftudy the drawings of Albert Durer; and fpared no pains or expence to acquire all the drawings he could meet with, that were taken frombafib relievos; things, which the art of en¬ graving has fince rendered fo common as to be in every one’s hands. This art of multiplying drawings by means of the graver is of the fame date, and boafts the fame advantages, with the art of printing, by means of Which the works of the mind are multiplied, as it were, at one ftroke, and difpcrfed over the whole world. The fight of fine fubjc&s treated by able mafters, and the different forms which the fame fubje&s affume in different hands, cannot fail both of enlightening and enflaming the mind of the young painter. The fame maybe faid of the perufal of good poets and hifto- . * rians, with the particulars and proofs of what they ad¬ vance ; not to mention thofe ideas and flights of inven¬ tion, with which the former are wont to clothe, beauti¬ fy, and exalt every thing they take in hand. Bouch- ardon, after reading Homer, conceited, to ufe his own words, that men were three times taller than be¬ fore, and that the world was enlarged in every refpedf. It is very probable, that the beautiful thought of co¬ vering Agamemnon’s face with the fkirt of his mantle, at the facrifice of Iphigenia, was fuggefted to Timan- tes by the tragedy of Euripides. And the fublime con¬ ceit of Raphael, who, in a Creation of his, reprefents God in the immenfe fpace, with one hand reaching to the fun and the other to the moon, may be confidered as the child of the following1 words of the Pfalmift: “The heavens declare the glory of God, and the firmament Jhehueth his handy-work. This thought of Raphael has been, indeed, cenfured by Mr Webb. “ A God,” fays this gentleman, “ ex¬ tending one hand to the fun, and another to the moon, deflroys that idea ofimmenfity, w'hich fhould accompany the work of creation, by reducing it to 'a world of a few inches.” But the opinion of Count Algarotti is very different. “ For my part,” fays that, elegant critic, “I cannot difcover,in this painting, a world of a few inches, but a world on a much greater fcale; a world of millions and millions of miles : and yet this fo immenfe a world, by means of that aft of the Godhead, in which with one hand he reaches to the fun, and with the other to the moon, (brinks, in my imagination, to a mere no¬ thing, in refpeft to the immenfity of God himfelf; which is all that the powers of painting can pretend to. This invention is, though in a contrary fenfe, of the fame kind with that of Timantes, who, to exprefs the enormous fize of a deeping Polyphemus, placed round him fome fatires meafuring the mender’s thumb Part I. with a thyrfus. Hence Pliny, who relates the faft, Books for a takes occafion to tell us, that his works always imply Painty- more than they exprefs ; and that how great foever he-*^1 may be in execution, he is dill greater in invention : Atque in omnibus ejus operibus intelligitur plus femper quam pingitur ; et cum ars fumma fit, ingenium tamen ultra artemejl." Nat. Hilt. lib. xxxv. c. x. The perufal of good authors cannot but be very ferviceable to a painter in another refpeft ; as, among the great number of fubjefts afforded by hiftory and poetry, he may expeft to meet with many on which his talents may difplay themfelves to the greateft ad¬ vantage. A painter can never be too nice in the choice of his arguments ; for on the beauty of them, that of his piece will greatly depend. How much to be pi¬ tied, therefore, were our firft mafters, in being fo of¬ ten obliged to receive their fubjefts from the hands of Ample and illiterate perfons ! and what is worfe, to fpend all the riches of their art upon barren or unwor¬ thy fubjefts! Such are the reprefentations of thofe faints, who, though they never had the lead inter- courfe with each other, and perhaps even lived in different ages, are, notwithftanding, to be introduced, tete a tete, as it were, in the fame pifture. The me¬ chanic of fhe art, may, indeed, difplay itfelf on thefe occafions; but by no means the ideal. The difpofi- tion may be good and praife-worthy, as in the works of Cortona and Lanfranc ; but we are not to expeft in them either invention of exprefiion, which require for their bafis the reprefentation of fome faft capable of producing fnch effefts. Who does not, on the bare mention of this abhfe, immediately recolleft many fad inftances of it ? fucli as the famous St Csecilia of Ra¬ phael, furrounded by St Paul, St Mary Magdalen, St John, and St Auguftin ; and the pifture of Paolo Ve* ronefe, in the veftry of the NunS of St Zachary at Ve¬ nice, in which St Frances of Alfizium, Saint Catha¬ rine, and St Jerome richly habited in his cardinal’s robes, form a ring round the Virgin feated on a throne with the child Jefus in her arms ; perhaps the moft beautiful and pifturefque of all the infipidand infigni- ficant pieces with which Italy abounds. It is very (hocking to think, that young painters (hould be ob¬ liged to ftudy their art from fuch wretched compofi* tions. The fubjefts in which the pencil triumphs moft, and with which a judicious painter may (lock himfelf by the perufal of good books, are, no doubt, thofe which are moft; univerfally known, which afford the largeft field for a difplay of the paflions, and contain the greatell variety of incidents, all concurring, in the fame point of time, to form one principal action. Of this the ftory of Coriolanus befieging Rome, as related by Livy, is a (hining example. Nothing can be ima¬ gined more beautiful than the feene of aftion itfelf, which ought to take in the pretorium in the camp of the Volfcians, the Tiber behind it, and the feven hills, among which the towering Capitol is, as it were, to lord it over the reft. It is impoflible to conceive a greater variety, than what mu ft appear in that crowd of foldiers, women, and children, all which are to en¬ ter the compofition; unlefs, perhaps, it be that of the different paffions with which they are feverally agita¬ ted ; fome wiftiing that Coriolanus may raife the fiege, cthtrt fearing it, others again fufpefting it.

Sect. XV. Of the Painter’s Balance. 18. Thb Celebrated de Piles, who by his wri¬ tings, has thrown fo much light upon painting, in or¬ der to affift young painters in forming a right judg¬ ment of thofe mafters who hold the firft rank in the pro- feffion, and to reduce fuch judgment to the greater pre- cifion, bethought himfelfof a pidlorical balance, by means of which a painter’s merit may be weighed with the greateft exadlnefs. This merit he divides into Compoli- lion, Defign, Colouring, and Expreffion ; and in each of thefe branches he has affigned every painter that fhare he thought him entitled to, according as he ap¬ proached more or lefs the higheft degree of excellence and fummit of perfediion; fo that, by fummiog up the numbers which, {landing againft each mailer’s name, exprefs his fhare of merit in each of thefe branches, we have his total merit or value in the art, and may hence gather what rank one painter holds See Mal- in regard to another. Several objedlions, it is true, marks^ in ^een ^arlec^ to method of calculation, by a Mem.’de famous mathematician of our days, who, among other t'Acad des things, infills, that it is the produdt of the above Sciences, numbers multiplied by each other, and not the fum 0f them, that gives the merit of the artill. But this is not a place to enter into fuch niceties, nor indeed would the doing it be of any fervice to the art. The only thing worth our notice is, whether the original numbers, Handing for the painter’s merit in the feveral branches of his art, are fuch as he is really intitled to, without fuffering ourfelves to be biaffed by any partia¬ lity, as de Piles has been, in favour of the prince of the Fltmilh fchool; the confequence of which, llrange as it may appear, is, that in his balance Raphael and Rubens turn out exadlly of the fame weight. Raphael is now univerfally allowed to have attained that degree of perfedlion, beyond which it is fcarce lawful for mortals to afpire. Painting, in fome mea- fure, revived among us by the diligence of Cimabue, towards the decline of the 13th century, received no fmall improvements from the genius of Giotto, Mafac- AlgaroUt. c'°» an^ others ; infomuch that, in lefs than 200 years, it began to blaze forth with great luftre in the works of Ghirlandai, Gian Bellino, Mantegna, Pietro Perugino, and Leonardo da Vinci, the bell grounded of them all, a man of great learning, and the firft who contrived to give relief to piflures. But whatever im¬ provement the art might have received from thefe dif¬ ferent mafters in different parts of Italy, they Hill, to a man almoft, fervilely followed the fame manner, and all partook more or lefs of that hardnefs and drynefs, which, in an age ftill Gothic, painting received from the hands of its reftorer Cimabue; till Raphael, at length, iffuing from the Peruginian fchoolj andj ftudy- TING. 5817 ing the works of the Greeks, without ever lofing fight Painters of nature, brought the art, in a manner, to the higheft ,nce- pitch of perfedion. This great man has, if not en¬ tirely, at lead in a great meafure, attained thofe ends which a painter fhould always propofe to himfelf, 10 deceive the eye, fatisfy the underftanding, and touch the heart. So excellent are his pieces, that the fpec- tator, far from praifing his pencil, feems fometimes en¬ tirely to forget that they are the feats of it which he has before him; folely intent upon, and as it were tranf- ported to, the feene of adion, in which he almoft fan¬ cies himfelf a party. Well, indeed, has he deferved the title of divine, by the beauty and comprehenlive- nefs of his expreffion, the juftnefs and noblenefs of his compofitions, the chaftity of his defigns, and the ele¬ gance of his forms, which always carry a natural in¬ genuity along with them ; but above all, by that in- expreflible gracefulnefs, more beautiful than beauty ' itfelf, with which he has contrived to feafon all his pieces. Carlo Marrati having engraved a piece, called the School, placed at the top of it the three Graces, with this verfe under them, Seneza di noi ogni fatica S vana ; “ Without our aid, all labour is in vain.” Without their aid, in fad, the light of a pidure is no better than darknefs, every attitude is infipid, every motion auwkward. It is they who impart to every thing that jhe tie fgai quoi, that charm, which is as fure to conquer, as impoflible to be defined. Maratti has placed the Graces on high, and, as it were, de¬ fcending from heaven, in order to ftiew that they real¬ ly are a celeftial gift. Happy the artift on whole cradle they have fmiled, whofe vows and offerings they have not difdained! Maratti was not to be in¬ formed, that gracefulnefs, that jewel which adds fuch value to every thing, tho’ not originally obtainable by all the gold of diligence and ftudy, may yet be greatly heightened and polilhed by them. Though Raphael might boaft, like Apelles * of old, * 7. whom he refembled info many other refpeds, that in InftftA. xH, gracefulnefs he had no equal ; yet Parmigiano andc- Correggio muft be allowed to have come very near him. One of them has, however, often trefpaffed the juft bounds of fymmetry; and the other is not always challe in his defigns : both, befides, were too apt to be guilty of affedlation. We ought perhaps to forgive AUaroiu. Corregio every thing, for the fake of that uncommon greatnefs of manner, that life and foul, which he has infufed into all his figures; for the fake of that inimi¬ table cafe and delicacy of pencil, which makes his pieces appear as if finilhed in a day, and feen in a glafs. Of this we have a fufficient proof in the An¬ cona of St Jerome and the Magdalen on their knees before the child Jefus, which is in Parma ; the fineft piflure, perhaps, that ever iffued from mortal hands. There are fome glimpfes of Corregio’s ftyle in the works of Barocci, though he ftudied at Rome. He never drew a figure that he did not borrow from na¬ ture ; and, for fear of lofing the maffes, ufed to drape his models with very large folds. His pencil was ex¬ ceedingly fweet, and his colouring equally harmo¬ nious. He indeed fpoiled a little the natural tints by too free an ufe of reds and blues; and has now and then robbed things of their body, by {hading them too much, and melting them, as it were, into one ano- 32 U 2 ther. 58iB Painter’s then In point of defign, he was far more diligent Balance. t^an fuccefsful. ;n the ai'r of his heads, affefted the gracefulnefs of the Lombard fchool, rather than the elegance of the Greeks and his countryman Ra¬ phael. Julio Romano, full of fpirit, and of learning and uncommon conceits, feems to come nearer the manner of Michael Angelo than the elegantly natural one of Raphael, under whom he ftudied; The Germans, by fervilely following Michael An¬ gelo, gave into thofe ftrange attitudes and clumfy forms which appear in the works of their greateft men, Sprangher and Golzio. The Florentines copied him with greater judgment and difcretion. We muft, however, except Andrea del Sarto, who, though an obferver of truth, is fome- what clumfy in his figures. But then he is eafy in his draperies ; fweet in his colours ; and would have car¬ ried the palm among the Tufcans, had it not been ra- vilhed from him by Fra. Bartolomeo ; to immortalife whom, his St Mark in the palace of Pitti would alone be fufficient; for there is not wanting in. that piece any of the perfections neceflary to conftitute an excel¬ lent matter. Titian, whom Giorgione firtt imitated in the art, is an univerfal matter. Upon every thing he took in band, he has contrived to ttamp its own proper na¬ ture. His pencil flows with juices that are truly vi¬ tal. His figures breathe ; and the blood circulates in their faces. And though fome perhaps have furpaffed him in defign ; not but that he is generally correft enough in the bodies of his women ; and his children, on account of their form, have been ftudied by the f Bellori’s greateft matters f; he never had his equal in colouring, %vel°f , or in portrait and landfcape painting.

He moft indefatigably laboured to convert, if we may be allowed the exprellion, the colours of his pallet in¬ to flefh and blood. But what coft him moft was, as he himfelf confeffes, to cover and hide his fatigue: and in this he has fucceeded fo well, that his works feem rather born than made. His fortune equalled his merit. He was greatly honoured by Charles V. as the great Raphael had been, a few years before, by the Popes Julius II. and Leo X. Jacopo Baffano diftinguiftied himfelf, at the fame time, by the ftrength of his colouring. Few have equalled him in the juft difpenfation of light reflefted from one obje& to another, and in thofe happy con- trafts by means of which painted objefts become re¬ ally tranfparent. He may boaft his having deceived an Aunibal Caracci, as Pharrhafio formerly deceived Zeuxes; and had the glory of Paolo Veronefe’s not being willing that his fon Carletto ihould learn the principles of colouring from any other mafter. Paolo Veronefe was the creator, as it were, of a new manner. Though carelefs in point of defign, and in point of coftume extremely licentious, he was noble of fancy, and moft fruitful of invention. One would imagine, that thofe who behold his magnificent pic¬ tures longed to be of the adtion reprefented by them ; and it may be faid of him with great juftice, that even his faults are pleafing. He has had very great admi¬ rers in every age ; and among them a Guido Reni, whole praife, no doubt, would have flattered him moft. Part I. Tintoret is no way inferior to any of the Venetians IPainter’s in thofe pieces which he drew by way of difplaying Bala»ce- his talents, and not improving them. This he has particularly fhown in his Martyrdom, now in the fchool of St Mark ; in which there is defign, colouring,.com- pofition, effefts of light, life, expreflion, and all car¬ ried to the higheft pitch of perfedlion. Scarce had this pi&ure made its appearance, when all mankind feemed to fall in love with it. Aretine himfelf, tho’ fo warm a friend to Titian,'that, through mere jea- loufy he turned Tintoret out of his fchool, could not forbear crying it up to excefs. He wrote himfelf to jtaccoha di Tintoret, that this piece had extorted the applaufe Letters Julia all thofe who faw it. The fccne, adds he, appears ra- ther true than feigned ; and happy would you be, if, j“cbUettu- inftead of being fo expeditious, you could prevail on r0;Xom.iii. yourfelf to be a little more patient. let. 6$. Next to thefe great artifts, who had no guide but nature, or the moft perfeA copies of nature, the Greek ftatues, ftarted up thofe other artifts, whom we are not to confider as the difciples of nature, fo much as of thofe mafters who a little before had revived the art of painting, and reftored it to its ancient honour and dig¬ nity. Such were the Caraccis, who undertook to u- nite in their manner the beauties of all the moft famous Italian fchools, and founded a new one, which did not yield to the Roman in elegance cf forms, to the Flo¬ rentine in correftnefs of defign, nor to the Venetian or Lombard in beauty of colouring. Thefe fchools, if we may be allowed the expreflion, are the primitive metals of painting ; and the Caraccis, by melting them down together, compofed a Corinthian metal, noble indeed and beautiful to lookat, but wanting the ftrength, du&ility, and weight, poffeffed fingly by the different metals which compofe it. And indeed the greateft praife that can be beftowed on the works of the Ca¬ raccis, is not owing to any air of originality in them, or any perfecl imitation of nature, but to the ftriking likenefs in them to the manner of Titian, Raphael, Parmigianino and Correggio. As to the reft, the Ca¬ raccis did not negledt to provide their fchool with all thofe helps which learning could afford; from a con- viftion that the arts never fucceed through mere good fortune or boldnefs of fancy, but are rather fo many habits working according to the di&ates of learning and right reafon. In their fchool, the pupils were taught perfpe&ive, anatomy, in a word every thing neceffary to lead them by the fhorteft and fafeft road. And it is to this that we are chiefly to attribute the fchool of Bologna’s having produced a greater number of able mafters than any other. At the head of thefe mafters Hand Domenichino and Guido; one a moft curious obferver of nature, and moft profound painter; the other the inventor of a certain noble and beautiful manner peculiar to himfelf,. which ihines efpecially in that fweetnefsand beauty he has contrived to give the faces of his women. Both thefe artifts have been preferred to the Caraccis; and it muft be owned, that the laft did really excel them. Francefco Barbieri, called il Guercino, ftudied firft in this fchool; but he afterwards formed to himfelf a certain peculiar manner, entirely founded upon nature and truth. Quite carelefs in the choice of his forms* he produced a chiarofcuro that gives the greateft relief to objefts, and renders them palpable. Caravaggio, PAINTING. PAINTING. Part L Painter’s the Rembrants of Italy, was the real author of this Balance, manner which, in thefe our days, has been again " brought to light by Piazetta and Crefpi. He abufed the faying of that Greek, who being allied, who was his mailer, pointed to the populace; and fucb, in¬ deed, was the magic of his chiarofcuro, that, as often as he undertook to copy nature in low and trivial fub- je&s, he had the power of deceiving even a Domeni- chino and a Guido. The ftyle of Caravaggio was fol¬ lowed by two famous Spaniards; Valefquez, the foun¬ der of a fchool among his countrymen; and il Ribera, who fettled in Italy, and from whom afterwards the whimlical Salvator Rofa, and that moil fertile genius Lucas Giordano, the Proteus and thunderbolt of paint¬ ing, itudied the firil principles of the art. Between the mailers of the Bolognian and thofe of the other fchools of Italy, we are to place Rubens, the prince of the Flemiih fchool, and a man of the moil elevated genius, who appeared, at once, as painter and ambaffador in a country, which, in a few years after, faw one of its greateft poets fecretary of iiate. Nature endowed him with great vivacity, and great cafe is working; and he added learning to thefe na¬ tural gifts. He, too, ftudied our mailers, Titian, Tintoret, Caravaggio and Paulo ; and borrowed a little from every one of them, fo fparingly, however, that his own peculiar manner predominates. He was in his movements more moderate than Tintoret, more foft in his chiarofcuro than Caravaggio; but not fo rich in his compofitions, or light in his touches, as Pa¬ olo; and, in his carnations, always lefs true than Ti¬ tian, and lefs delicate than bis own fcholar Vandycke. He contrived to give his colours the greateft tranfpa- rency, and no lefs harmony, notwithftanding the ex¬ traordinary deepnefs of them ; and he had a ftrength and grandeur of llyle entirely his own. He would have foared Hill higher, had nature afforded him finer objects in Flanders, or had he known how to create them anew, or correft them after the patterns left us by the Greek mafters. Poufiin, the prince of French painters, had a par¬ ticular fondnefs for the works of Rubens, at the fame time that he fought for the art of defign amoag the ancient marbles, in which, as an ingenious author ex- preffes it, Ihe fits as Queen to give law to the mo¬ derns. He fpared no pains in the choice and compo- fition of his fubjefls; and gave them life, learning, and dignity. He would have equalled Raphael himfelf, whofe ftyle he imitated ; were gracefulnefs, eafe, and vivacity, to be acquired by ftudy. For, in fad, it was by mere dint of labour and fatigue, that he produced what in a manner coft Raphael nothing; infomuch, that his figures may be faid to mimic the natural ac¬ tions of that great mafter. Sect. XVI. Of Imitation. 19. A painter ought attentively to confider, com¬ pare together, and weigh in the balance of reafon and truth, all thefe different llyles. But he ought likewife carefully to guard againft too great a fondnefs for any one of them in particular th-it he may think proper to adopt; otherwife, to ufe the Dantefque exprtffion of a firft-rate mafter f, inftead of the child, he would be--| come the grand-child, of nature. 0 Befides, his imitation mult be of generals and not of particulars. Whatever a young painter’s natural dif- pofrtion may be, whether to paint boldly and freely like Tintoret and Rubens, or to labour his works like Ti¬ tian or da Vinci, let him follow it. This kind of imi¬ tation is very commendable. It is thus that Dante, at the fame time that he carefully avoided adopting the particular expreffions of Virgil, endeavoured to feize his bold and free manner, and at laft caught from him that elegance of ftyle which has done him fo much honour. 20. As to the reft, nothing fhould hinder an able ma¬ fter from making ufe now and then of any antique, or even modern figure, which he may find his account in employing. Sanzio, in a St Paul at Lijlra, fcrupled not to avail himfelf of an ancient facrifice in baffo-re- lievo ; nor did Buonarroti himfelf difdain to ufe, in his paintings of the Sextine chapel, a figure taken from that famous cornelian which tradition tells us he wore on his fingers, and which is now in the poffelfion of the mod Chriftian King. Men like thefe avail themfelves of the produdlions of others in fuch a manner as to make us apply to them, what La Bruyere faid of Defpreaux, that one would imagine the thoughts of other men had been of his own creation. In general, a painter (hould have his eye conftantly fixed on nature, that inexhauftible and varied fource of every kind of beauty; and fhould ftudy to imitate her in her moft fingular effedls. As beauty fcattered over the whole univerfe, fhines brighter in (ome objefls than in others, he ftiould never be without his little book and crayon, in order to make drawings of every beau¬ tiful or uncommon object that may happen to prefent itfelf; ^nd take flcetches of every fine building, every fituation, every effedl of light, every flight of clouds, every flow of drapery, every attitude, every exprtfiion of the paffionsj that may happen to ftrike him. He may afterwards employ thefe things as Occafions offer; and in the mean time will have the advantage of acqui¬ ring a grand tafte. By uniting in a grand compofi- tion effects no lefs bold and beautiful than true and natural, he will acquire the fame glory that orators ac¬ quire by the fublime, the glory of furprifing, and in a; manner exalting us above ourfelves.

Landfcapes diverfified nuith waters, as rivers, lakes, catarafts, &c.; which require a peculiar talent, toexprefsthe water fometimes fmooth and tranfparent, and at others foaming and rufhing furioufly along. VIII. Sea-pieces ; in which are reprefented the ocean, harbours, and great rivers ; and the veffels, boats, barges, &c. with which they are covered ; fometimes in a calm, fometimes with a frefh breeze, and at others in a ftorm. In this clafs Backhuyfen, Vandervelde, Blome, and many others, have acquired great reputa¬ tion. IX. Night-pieces; which reprefent all forts of objects, either as illuminated by torches, by the flames of a conflagration, or by the light of the moon. Schalck, Vanderneer, Vanderpool, &c. have here excelled. X. Living Animals ; A more difficult branch of painting than is commonly imagined; and in which Rofa, Carre, Vandervelde, and many others, have fuc- ceeded marvelloufly well. XI. Birds of all kinds ; a very laborious fpecies, and which requires extreme patience minutely to exprefs the infinite variety and delicacy of their plumage. Culinary pieces ; which reprefent all forts of pro- • vifions, and animals without life, &c. A fpecies much inferior to the reft, in which nature never appears to advantage, and which requires only a fervile imitation of objedTs that are but little pleafing. The painting of fifties is naturally referred to this clafs. XIII. Fruit pieces, every kind, imitated from na¬ ture. XIV. Flower-piedts ; a charming clad of painting, where Art in the hands of Huyzum, P. Segerts, Me- rian, &c. becomes the rival of Nature. Plants and in- Jells are ufually referred to the painters of flowers, who with them ornament their works. XV. Pieces of architefture; a kind of painting in which the Italians excel all others. Under this clafs may be comprehended the reprefentations of ruins, fea- ports, ftreets, and public places; fuch as are feen in the works of Caneletti, and other able matters. XVI. Injlruments of mufic, pieces of furniture, and other inanimate objefts; a trifling fpecies, and in which able painters only accidentally employ their talents. XVII.

If. Of Landfcape. 22. LANDSCAPE-painting includes every objedl that the country prefents: And is diftinguiftied into the he¬ roic, and the pajloral or rural} of which indeed all other ttyles are but mixtures. The heroic ftyle is a compofuion of objedls, which in j)c p;ies fn their kinds draw both from art and nature every thing Paiming. that is great and extraordinary in either. The fitua- tions are perfe&ly agreeable and furprifing. The only buildings are temples, pyramids, ancient places of bu¬ rial, altars confecrated to the divinities, pleafure-houfes of regular architecture ; and if nature appear not there as we every day cafually fee her, fhe is at leaft repre¬ fented as we think (he ought to be. This ftyle is an agreeable illufion, and a fort of enchantment, when handled by a man of fine genius and a good under- ftanding, as Pouffin was, who has fo happily expreffed it. But if, in the courfe of this ftyle, the painter has not talent enough to maintain the fublime, he is often in danger of falling into the childilh manner. The rural Jlyle is a reprefentation of countries, ra¬ ther abandoned to the caprice of nature, than cultiva¬ ted : we there fee nature Ample, without ornament, and without artifice; but with all thofe graces wherewith Ihe adorns herfelf much more when left to herfelf than when conftrained by art. In this ftyle, fituations bear all forts of varieties : fometimes they are very extenfive and open, to contain the flocks of the (hepherds ; at others very wild, for the retreat of folitary perfons, and a cover for wild beafts. It rarely happens that a painter has a genius exten¬ five enough to embrace all the parts of painting: there is commonly fome one part that pre-engages our choice, and fo fills our mind, that we forget the pains that are due to the other parts; and we feldom fail to fee, that thofe whofe inclination leads them to the heroic ftyle, think they have done all, when they have introduced into their compofitions fuch noble objefls as will raife the imagination, without ever giving themfelves the trouble to ftudy the effe&s of good colouring. Thofe, on the other hand, who praCtife the paftoral, apply clofely to colouring, in order to reprefent truth more lively. Both thefe ftyles have their fe&aries and par- tifans. Thofe who follow the heroic, fupply by their imagination what it wants of truth, and they look no farther. As a counterbalance to heroic landfcape, it would be proper to put into the paltoral, befides a great cha- ra&er PAINTING. Part II. PAIN J.andfcape. rafter of truth, Tome affefting, extraordinary, but pro- bable effeft of nature, as was Titian’s cuftom. There is an infinity of pieces wherein both thefe ftyles happily meet; and which of the two has the af- cendant, will appear from what we have been juft ob- ferving of their refpeftive properties. The chief parts of landfcape are, their openings or fituations, acci¬ dents, ikies and clouds, off-ikips and mountains, ver¬ dure or turfing, rocks, grounds or lands, terraces, fa¬ brics, waters, fore-grounds, plants, figures and trees; of all which in their places. 23. Of Openings or Situations. The word ftte, or fituation, fignifies the “ view, profpeft, or opening of a country.” It is derived from the Italian word ftto; and our painters have brought it into ufe, either be- caufe they were ufed to it in Italy, or becaufe, as we think, they found it to be very exprefiive. Situations ought to be well put together; and fo dif- engaged in their make, that the conjunftion of grounds may not feem to be obftrufted though we fttould fee but a part of them. Situations are various, and reprefented according to the country the painter is thinking of: as either open or clofe, mountainous or watery, tilled and inhabited, or wild and lonely ; or, in fine, variegated by a prudent mixture of fome of thefe. But if the painter be obli¬ ged to imitate nature in a flat and regular country, he muft make it agreeable by a good difpofition of the elaro-obfcuro, an<\ fudh pleafing colouring as may make one foil unite with another. It is certain, that extraordinary fituations are very pleafing, and cheer the imagination by the novelty and beauty of their makes, even when the local colouring is but moderately performed: becaufe, at worft, fuch piftures are only looked on as unfinifhed, and wanting to be1 completed by fome fkilful hand in colouring; whereas common fituations and objefts require good colouring and abfolute finifhing, in order to pleafe. It was only by thefe properties that Claud Lorrain has made amends for his infipid choice in moft of his fitua¬ tions. But in whatever manner that part be executed, one of the beft ways’ to make it valuable, and even to multiply and vary it without altering its form, is pro¬ perly to imagine fome ingenious accident in it. Of Accidents. An accident in painting is an obftruftion of the fun’s light by the interpofition of clouds, in fuch manner, that fome parts of the earth fhall be in light and others in ftiade, which, according to the notion of the clouds, fucceed each other, and produce fuch wonderful effefts and changes of the claro~ obfcuro, as feem to create fo many new fituations. This is daily obferved in nature. And as this newnefs of fi¬ tuations is grounded only on the fhapes of the clouds, and their motions, which are very inconftant and un¬ equal, it follows, that thefe accidents are arbitrary; and a painter of genius may difpofe them to his own ad¬ vantage when he thinks fit to ufe them: For he is not abfolutely obliged to do it; and there have been fome able landfcape-painters who have never praftifed it> ei- through fear or cuftom, as Claude Lorrain and fome others. 25. Of the Sky and Clouds. The fky, in painters terms, is the ethereal part over our heads; but more particularly the air in which we breathe, and that where ■clouds and ftorms are engendered. Its colour is blue, TING. 5821 growing clearer as it approached the earth, becaufe of Landfcaje. of the interpofition of vapours arifmg between the eye and the horizon; which, being penetrated by the light, communicates it to objefts in a greater or leffer degree, as they are more or lefs remote. But we muft obferve, that this light being either yellow or reddifh in the evening, at fun-fet, thefe fame objefts partake not only of the light, but of the co¬ lour : thus the yellow light mixing with the blue, which is the natural colour of the fky, alters it, and gives it a tint more or lefs greenifh, as the yellownefs of the light is more or lefs deep. This obfeevation is general and infallible: but there is an infinity of particular ones, which the pain¬ ter muft make upon the natural, with his pencil in his hand, 'when occafion offers ; for there are very fine and Angular effefts appearing in the fky, which it is difficult to make one conceive by phyfical reafons. Who can tell, for example, why we fee, in the bright part of fome clouds, a fine red, when the fource of the light which plays upon them is a moft lively and diftinguifhing'yellow ? Who can account for the diffe¬ rent reds feen in different clouds, at the very moment that thefe reds receive the light but in one place? for thefe colours and furprifing appearances feem to have no relation to the rainbow, a phacnomenon for which the philofophers pretend to give folid reafons. Thefe effefts are all feen in the evening, when the weather is inclining to change, either before a ftorm, or after it, when it is not quite gone, but has left fome remains of it to draw our attention. The property of clouds is to be thin and airy, both in fhape and colour: their fhapes, though infinite, muft be ftudied and chofen after nature, at fuch times as they appear fine. To make them look thin, we ought to make their grounds unite thinly with them, efpecially near their extremities, as if they were tranf- parent: And if we would have them thick, their re- fleftions muft be fo managed, as, without deftroying their thinnefs, they may feem to wind and unite, if neceffary, with the clouds that are next to them. Little clouds often difcover a little manner, and feldom have a good effeft, unlefs when, being near each other, they feem all together to make but one objeft. In fhort, the charafter of the fky is to be lumi¬ nous; and, as it is even the fource of light, every thing that is upon the earth muft yield to it in bright- nefs: If however there is any thing that comes near it in light, it muft be waters, and polifhed bodies which are fufceptible of luminous refieftions. But, whilft the painter makes the fky luminous, he muft not reprefent it always finning throughout. On the contrary, he muft contrive his light fo, that the greateft part of it may fall only upon one place: and, to make it more apparent, he muft take as much care as poffible to put it in oppofition to fome terreftrial objeft, that may render it more lively by its dark colour; as a tree, tower, or fome other building that is a little high. This principal light might alfo be heightened, by a certain difpofition of clouds having a fuppofed light, or a light ingenioufly inclofed between clouds, whofe fweet obfcurity fpreads itfelf by little and little on all hands. We have a great many examples of this in the Flemifh fchool, which beft underftood landfkip; AS 5S22 PAIN ..Landfcape. as Paul Bril, Brcgel, Saver!: And the Sadelers and Merian’s prints give a clear idea of it, and wonderfully awaken the genius of thofe who have the principles of the clarofcuro. 26. Of Offjkips and Mountains. Offskips have a near affinity with the Iky ; it is the Iky which deter¬ mines either the force or faintnefs of them. They are darkeft when the fky is molt loaded, and brighteft when it is moft clear. They fometimes intermix their lhapes and lights; and there are times, and countries, where the clouds pafs between the moun¬ tains, whofe tops rife and appear above them. Moun¬ tains that are high, and covered with fnow, are very proper to produce extraordinary effefts in the off- ikip, which are adantageous to the painter, and plea- fing to the fpe&ator. The difpofition of offskips is arbitrary ; let them only agree with the whole together of the pi&ure, and the nature of the country we would reprefent. They are ufually blue, becaufe of the interpofition of air between them and the eye: but they lofe this colour by degrees, as they come nearer the eye, and fo take that which is natural to the obje£b. In diftancing mountains, we muft obferve to join them infenfibly by the roundings off, which the re¬ flections make probable ; and mult, among other things, avoid a certain edginefs in their extremities, which makes them appear in llices, as if cut with fciffors,-and (tuck upon the cloth. We mud further obferve, that the air, at the feet of mountains, being charged with vapours, is more fufceptible of light than at their tops. In this cafe, vve fuppofe the main light to be fet reafonably high, and to enlighten the mountains equally, or that the clouds deprive them of the light of the fun. But if we fuppofe the main light to be very low, and to ftrike the mountains ; then their tops will be ftrongly enlightened, as well as every thing elfe in the fame degree of light. Though the forms of things diminilh in bignefs, and colours lofe their ftrength, in proportion as they recede from the firft plan of the picture, to the mod remote offskip, as we obferve in nature and common praftice ; yet this does not exclude the ufe of the ac¬ cidents. Thefe contribute greatly to the wonderful in landfcape, when they are properly introduced, and when the art id has a jud idea of their good effe&s. 27. Of Verdure, or Turfing. By turling is meant the greennefs with which the herbs colour the ground: "This is done feveral ways ; and the diverfity proceeds not only from the nature of plants, which, for the moft part, have their particular verdures, but alfo from the change of feafons, and the colour of the earth, when the herbs are but thin fown. By this variety, a painter may choofe or unite, in the fame trail of land, feveral forts of greens, intermixed and blended together, which are often of great fervice to thofe who know how to ufe them ; becaufe this diver¬ fity of greens, as it is often found in nature, gives a charailer of truth to thofe parts, where it is properly ufed. There is a wonderful example of this part of landfcape, in the view of Mechlin, by Rubens. 28. Of Rocks. Though rocks have all forts of fliapes, and participate of all colours, yet there are, . in their diverfity, certain chara&ers which cannot be TING. Part II. well exprefled without having recourfe to nature. Landfcape. Some are in banks, and fet off with beds of ftrubs ; others in huge blocks, either projefting or falling back; others confift of large broken parts, contiguous to each other; and others, in fliort, of an enormous fize, all in one done, either naturally, ps free-done, or elfe through the injuries of time, which in the courfe of many ages has worn away their marks of feparation. But, whatever their form be, they are ufually fet out with clefts, breaks, hollows, bulhes, mofs, and the dains of time; and thefe particulars, well managed, create a certain idea of truth. Rocks are of themfelves gloomy, and only proper for folitudes : but where accompanied with bulhes, they infpire a frelh air; and, when they have waters, either proceeding from, or walhing them, they give an infinite pleafure, and feem to have a foul which animates them, and makes them fociable. 29. Of Grounds or Lands. A ground or land, in painters terms, is a certain didind piece of land, which is neither too woody nor hilly. Grounds con¬ tribute, more than any thing, to the gradation and didancing of landfeape ; becaufe they follow one ano¬ ther, either in fliape, or in the claro-tibfcuro, or in their variety of colouring, or by fome infenfible con- jun&ion of one with another. Multiplicity of grounds, though it be often con¬ trary to grand manner, does not quite dedroy it; for, befides the extent of country which it exhibit*, it is fufceptible of the accidents we have mentioned, and which, with good management, have afineeffeft. There is one nicety to be obferved in grounds, which is, that in order to charaderfze them well, care mud be taken, that the trees in them have a dif¬ ferent verdure and different colours from thofe grounds; though this difference, withal, mud not be too ap¬ parent. 30. Of Terraces. A terrace, in painting, is a piece of ground, either quite naked, or having very little herbage, like great roads and places often fre- . quented. They are of ufe chiefly in the foregrounds of a pidlure, where they ought to be very fpacious and open, and accompanied, if we think fit, with fome accidental verdure, and alfo with fome dones, which, if placed with judgment, give a terrace a greater air of probability. 31. Of Buildings. Painters mean by buildings any drudltires they generally reprefent, but chiefly fuch as are of a regular archite&ure, or at lead are mod con- fpicuous. Thus building is not fo proper a name for the houfes of country-people, or the cottages of Ihep- herds, which are introduced into the rural tade, as for regularand lhowy edifices, which are always brought into \.\\z heroic. Buildings in general are a great ornament in land- fcapes, even when they are Gothic, or appear partly in¬ habited and partly ruinous : they raife the imagination by the ufe they are thought to be defigned for; as appears from ancient towers, which feem to have been the habitations of fairies, and are now retreats for Ihepherds and owls. Pouffin has very elegantly handled the Roman man¬ ner of architedlure in his works, as Bourbon has done the Gothic ; which, however Gothic, fails not to give a fublime air to his land/capes. Little Bernard ha; intro- Part II. PAIN Landfcape. intt'bduced Into his facred hlftory what may be called ‘a Babylonian manner; which, extraordinary as it is, has its grandeur and magnificence. Nor ought fuch pieces of architefture to be quite rejefited : they raife the imagination ; and perhaps would fucceed in the heroic ilyie, if they were placed among half-dillant objefls, and if we knew how to ufe them properly. $1. Of Waters. Much of the fpirit of landfcape is owing to the waters which are introduced in it. They appear in divers manners ; fometimes impetuous, as when a ftorm makes-them overflow their banks; at other times rebounding, as by the fill of a rock ; at other times, through unufual preffure, gufliing out and dividing into an infinity of filver ftreams, whofe mo¬ tion and murmuring agreeably deceive both the eye and ear; at other times calm and purling in a fandy bed ; at other times fo ftill and (landing, as to become a faithful looking-glafs, which doubles all the objefts that are oppofite to it ; and in this (late they have more life than in the mod violent agitation. Confult Bour¬ don’s works, or at lead his prints, on this fubjedl^: he is one of thofe who have treated of waters with the greateft fpirit and beft genius. Waters are not proper for every fituation : but to exprefs them well, the artift ought to be perfeft matter of the exadlnefs of watery reflexions ; becaufe they only make painted water appear as real: for praftice alone, without exa&nefs, deftroys the effedl, and abates the pleafure of the eye. The rule for thefe reflections is very eafy, and therefore the painter is the lefs par¬ donable for negledting it. But it mutt be obferved, that though water be as a looking-glafs, yet it does not faithfully reprefent ob¬ jects but when it is ftill; for if it be in any motion, either in a natural courfe, or by the driving of the wind, its furface, becoming uneven, receives on its furges fuch lights and (hades, as, mixing with the appearance of the objeCts, confound both their lhapes and colours. 33. Of the Foreground of a Pifture. As it is the part of the foreground to ufher the eye into the piece, great care mutt be taken that the eye meet with good recep¬ tion ; fometimes by the opening of a fine terrace, whofe defign and wprkmanfhip may be equally curious; fometimes by a variety of well-diftinguifhed plants, and thofe fometimes flowered ; and at other times, by figures in a lively tafte, or other objeCts, either admi- 'rable for their novelty, or introduced as by chance. In a word, the artift cannot too much ftudy his foreground objeds, fince they atlraft the eye, imprefs the firft charaSer of truth, and greatly contribute to make the artifice of a picture fuccefsful, and to antici¬ pate our efteem for the whole work. 34. Of Plants. Plants are not always neceffary in foregrounds, becaufe, as we have obferved, there are feveral ways of making thofe grounds agreeable. But if we refolve to draw plants there, we ought to paint them exaCtly after the life ; or at lead, among fuch as we paint praCtically, there ought to be fome more fi- nifhed than the reft, and whofe kinds may be diftin- guifhed by the difference of defign and colouring, to the end that, by a probable fuppofition, they may give the others a charader of truth. What has been faid here of plants, may be applied to the branches and barks of treees. Vol. VIII, 1 TING. 5823 35. Of Figures. In compofing landfcape, the artift Landfcape- may have intended to give it a character agreeable to the fubjeCt he has chofen, and which his figures ought to reprefent. He may alfo, and it commonly happens, have only thought of his figures, after finiflting his landfcape. The truth is, the figures in moft landfcapes are made rather to accompany than to fuit them. It is true, there are landfcapes fo difpofed and fi- tuated, as to require only paffing figures ; which feve¬ ral good mailers, each in his ftyle, have introduced’, as Pouffin in the heroic, and Fouquier in the rural, with all probability and grace. It is true alfo, that refting figures have been made to appear inwardly ac¬ tive. And thefe two different ways of treating figures are not to be blamed, becaufe they aft equally, tho* in a different manner. It is rather inaftion that ought to be blamed in figures ; for in this condition, which robs them of all conneftion with the landfcape, they appear to be palled on. But without obftrufting the painter’s liberty in this refpeft, undoubtedly the bed way to make figures valuable is, to make them fo to agree with the charafter of the landfcape, that it may feem to have been made purely for the figures. We would not have them either infipid or indifferent, but to reprefent fome little fubjeft to awaken the fpefta- tor’s attention, or elfe to give the pifture a name of diftinftion among the curious. Great care muft be taken to proportion the fize of the figures to the bignefs of the trees, and other ob- jefts of the landfcape. If they be too large, the pic¬ ture will difeover a little manner; and if too fmall, .they will have the air of pigmies: which will deftroy the worth of them, and make the landfcape look enor¬ mous. There is, however, a greater inconvenience in making figures too l?rge than too fmall ; becaufe the latter at lead gives an air of greatnefs to all the reft. But as landfcape figtires are generally fmall, they muft be touched with fpirit, and fuch lively figures as will attraft, and yet preferve probability and a general union. The artift muft, in fine, remember, that as the figures chiefly give life to a landfcape, they muft be difperfed as conveniently as p- flible. 36. Of Frees. The beauty of trees is perhaps one of the greateft ornaments of landfcape ; on account of the variety of their kinds, and their frefhnefs, but chiefly their lightnefs, which makes them feem, as be¬ ing expofed to the air, to be always in motion. Though diverfity be pleafing in all the objefts of landlkip, it is chiefly in trees that it (hews its greateft beauty. Landlkip cbnfiders both their kinds and their forms. Their kinds require the painter’s particular ftudy and attention, in order to diftinguilh them from each other; for we muft be able at full fight to difeo¬ ver which are oaks, dims, firs, fycamores, poplars, willows, pines, and other fuch trees, which, by a fpe- cific colour, or touching, are diftinguifliable from all other kinds. This ftudy is too large to be acquired in all its extent; and, indeed, few painters have attained fuch a competent exaftnefs in it as their art requires. But it is evident, that thofe who come neareft to per- feftion in it, will make their works infinitely pleafing, and gain a great name. Befides the variety which is found in each kind of tree, there is in all trees a general variety. This is ob¬ ferved in the different manners in which their branches 32 X are 5824 _ PAIN I.andfcape. are difpofed by a fportof nature; which takes delight in making fome very vigorous and thick, others more dry and thin ; fome more green, others more red or yellow. The excellence of pradice lies in the mix¬ ture of thefe varieties : but if the artift can diftinguilh the forts but indifferently, he ought at leaft to vary their makes and colours ; becaufe repetition in land- fcape is as tirefome to the eye, as monotony in dif- courfe is to the ear. The variety of their makes is fo great, that the pain¬ ter would be inexcufable not to put it in pra&ice up¬ on occafion, efpecially when he finds it neceffary to awaken the fpe&ator’s attention ; for, among trees, we difcoVer the young and the old, the open and clofe, tapering, and fquat, bending upwards and downwards. Hooping and Ihooting : in fliort, the variety is rather to be conceived than exprefled. For inftance, the cha- rader of young trees is, to have long (lender branches, few in number, but well fet out; boughs well divided, and the foliage vigorous and well fhaped : whereas, in old trees, the branches are fhort, ftocky, thick, and numerous; the tufts blunt, and the foliage unequal and ill fiiaped : but a little obfervation and genius will make us perfedly fenfible of thefe particulars. In the various makes of trees, there muft alfo be a diftribution of branches, that has a juft relation to, and probable connedion with, the boughs or tufts, fo as mutually to affift each other in giving the tree an ap¬ pearance “of thicknefs and of truth. But, whatever their natures or manners of branching be, let it be re¬ membered, that the handling muft. be lively and thin, in order to preferve the fpirit of their characters. Trees likewife vary in their barks, which are com¬ monly grey; but this grey, which in thick air, and low and marfhy places, looks blackifh, appears lighter in a clear air: and it often happens, in dry places, that the bark gathers a thin mofs, which makes it look quite yellow ; fo that, to make the bark of a tree ap¬ parent, the painter may fuppofe it to be light upon a dark ground, and dark on a light one. The obfervation of the different barks merits a par¬ ticular attention; for it will appear^ that, in hard woods, age chaps them, and thereby gives them a fort of embroidery ; and that, in proportion as they grow old, thefe chaps grow more deep. And other acci¬ dents in barks may arife either from moifture, or dry- nefs, or green moffes, or white ftains of feveral trees. The barks of white woods will alfo afford much matter for praftice, if their diverfity be duly ftudied : and this confideration leads us to fay fomething of the ftudy of landfkip. 37. Of the Jiudy of Landfcape. The ftudy of land- fcape may be confidered either with refpeft to be¬ ginners, or to thofe who have made fome advances in it. Beginners will find, in pra&ice, that the chief trouble of landfcape lies in handling trees ; and it is not only in praftice, but alfo in fpeculation, that trees are the moft difficult part of landfcape, as they are its greateft ornament. But it is only propofed here, to give beginners an idea of trees in general, and to (hew them how to exprefs them well. It would be need- lefs to point out to them the common effefts of trees and plants, becaufe they are obvious to every one; TING. Part II. et there are fome things, which, though not un- Landfcapa. nown, deferve our refle&ion. We know, for in- fiance, that all trees require air, fome more, fomelefs, as the chief caufe of their vegetation and produdtion ; and for this reafon, all trees (except the cyprefs, and fome others of the fame kind) feparate in their growth from one another and from other ftrange bodies as much as pofiible, and their branches and foliage do the fame: wherefore, to give them that air and thin- nefs, which is their principal charafter, the branches, boughs, and foliage, muff appear to fly from each other, to proceed from oppofite parts, and be well di¬ vided. And all this without order; as if chance aid¬ ed nature in the fanciful diverfity. But to fay parti¬ cularly how thefe trunks, branches, and foliages, ought to be diftributed, would be needlefs, and only a defcription of the works of great mafters: a little refle&ion on nature will be of more fervice than all that can be faid on this head. By great mafters, we mean, fuch as have publifhed prints; for thofe will give better ideas to young copyifts, than even the paint¬ ings themfelves. Among the many great mafters of all fchools, Da Pile prefers Titian’s wooden prints, where the trees are well-fhaped ; and thofe which Cornelius Cort, and Agoftino Carracche, have engraved. And he afferts, that beginners can do no better than contradl, above all things, an habif of imitating the touches of thefe great mafters, and of confidering, at the fame time, the perfpe&ive of the branches and foliages, and ob- ferving how they appear, either when rifing and feen from below, or when finking and feen from above, or when fronting and viewed from a point, or when they appear in profile; and, in a word, when fet in the various views in which nature prefents them, with¬ out altering their charadlers. After having ftudied and copied, with the, pen or crayon,- firft the prints, and then the defigns of Ti¬ tian and Carracche, the ttudent fhould imitate with the pencil thofe touches which they have moft diftindl- ly fpecified, if their paintings can be procured: but fince they are fcarce, others ihould be got which have a good character for their touching; as thofe of Fou- quier, who is a moft excellent model: Paul Bril, Breu- gel, and Bourdon, are aifo very good; their touch¬ ing is neat, lively, and thin. After having duly weighed the nature of trees, their fpread and order, and the difpofition of their branches, the artift muft get a lively idea of them, in order to keep up the fpirit of them throughout, either by making them apparent and diftinft. in the fore¬ grounds, or obfcure and confufed in proportion to their diftance. After having thus gained fome knowledge in good manner, it will next be proper to ftudy after nature, and to choofe and reftify' it according to the idea which the aforefaid great mafters had of it. As to perfeftioh, it can only be expefted from long pradlice and perfeverance. This, we think, is what concerns thofe, who, having an inclination for landfcape, would take the,proper methods for beginning it well. As for thofe who have made fome advances in this part of painting, it is proper they fhould colledl the neceffary materials for their further improvement, and ftudy Part II. PAIN Landfcape. ftudy thofe objefls at leaft, which they fhall have moft ' frequent occafion to reprefent. Painters ufually comprife, under the word Jludy, any thing whatever, which they either defign or paint fe- parately, after the life ; whether figures, heads, feet, hands, draperies, animals, mountains, trees, plants, flowers, fruits, or whatever may confirm them in the juft imitation of nature: the drawing of thefe things is what they callJludy} whether they be for inftruc- tion in defign, or only to affure them of the truth, and to perfect their work. In fatft, this word Jludy is the more properly ufed by painters, as in the di- verfity of nature they are daily making new difcove- ries, and confirming themfelves in what they already know. As the landfcape-painter need only ftudy fuch ob¬ jects as are to be met with in the country, we would recommend to him fome order, that his drawing's may be always at hand when he wants them. Forinftance, he ftiould copy after nature, on feparate papers, the different effedts of trees in general, and the different ef¬ fects of each kind in particular, with their trunks, fo¬ liage, and colours. He fliould alfo take the fame me¬ thod with fome forts of plants ; becaufe their variety is a great ornament to terraces on fore-grounds. He ought likcwife to ftudy the effedts of the Iky in the fe- veral times of the day, and feafons of the year, in the various difpofitions of clouds, both in ferene, thun¬ dering-, and ftormy weather; and in the off-ikip, the feverai forts of rocks, waters, and other principal ob- jedts. Thefe drawings, which may be made at times, ftiould be colledted together; and all that relate to one mat¬ ter be put into a book, to which the artift may have recourfe at any time for what he wants. Now, if the fine effedts of nature, whether in (hape or colour, whether for an entire pidfure or a part of one, be the artift’s ftudy; and if the difficulty lies in choofing thofe effedts well, he muft for this purpofe be born with good fenfe, good tafte, and a fine genius; and this genius muft; be cultivated by the obfervations which ought to be made on the works of the beft ma¬ tters, how they choofe nature, and how, while they corredled her, according to their art, they preferved her charadlcr. With thefe advantages, derived from nature, and perfedVed by art, the painter cannot fail to make a good choice ; and, by diftinguiftiing be¬ tween the good and the bad, muft needs find great in- ftrudlion, even from the moft: common things. To improve themfelves in this kind of ftudies, pain¬ ters have taken feverai methods. There are fome artifts who have defigned after na¬ ture, and in the open fields; and have there quite fi- nifhed thofe parts which they had chofen, but without adding any colour to them. Others have drawn, in oil-colours, in a middle-tint, on ftrong paper ; and found this method convenient, becaufe, the colours finking, they could put colour on colour, though different from each other. For this purpofe they took with them a flat box, which com- modioufly held their pallet, pencils, oil, and colours. This method, which iwdeed requires feverai imple¬ ments, is doubtlefs the beft for drawing nature more particularly, and with greater exadnefs, efpecially if, after the work be dry and varnifhed, the artift return TING. 5825 to the place where he drew, and retouch the principal Landfcape, things after nature. — Others have only drawn the out-lines ofobje&s, and flightly wafhed them in colours near the life, for the eafeof their memory. Others have attentively obferved fuch parts as they" had a mind to retain, and content¬ ed themfelves with committing them to their memory, which upon occafion gave them a faithful account of them. Others have made drawings in paftil and wafh together. Others, with more curiofity and patience, have gone feverai times to the places which were to their tafte : the firft: time they only made choice of the parts, and drew them corredly ; and the other times were fpent in obferving the variety of colouring, and its alterations through change of light. Now thefe feverai methods are very good, and each may be pra&ifed as beft fuits the ftudent and his tem¬ per : but they require the neceffaries of painting, as colours, pencils, paftils, and leifure. Nature, how¬ ever, at certain times, prefents extraordinary, but tranfient beauties, and fuch as can be of no fervice to the artift who has not. as much time as is neceffary to imitate what he admires. The beft way, per¬ haps, to make advantage of fuch momentary occafions, is this: The painter being provided with a quire of paper, and a black-lead pencil, let him quickly, but flightly, defign what he fees extraordinary; and, to remember the colouring, let him mark the principal parts with chara&ers, which he may. explain at the bottom of the paper, as far as is neceffary for himfelf to underhand them : a cloud, for inftance, may be marked A, ano¬ ther cloud B, a light C, a mountain D, a ter¬ race E, and fo on. And having repeated thefe let¬ ters at the bottom of the paper, let him write again ft each, that it is of fuch or fuch a colour ; or for grea¬ ter brevity, only blue, red, violet, grey, &c. or any other fliorter abbreviation. After this, he muft; go to painting as foon as poflible; otherwife moft of what he has oblerved will, in a little time, flip out of his memory. This method is the more ufeful, as it not only prevents our lofing an infinity of fudden and tran- fitory beauties, but alfo helps, by means of the afore- faid marks and chara&ers,to perfedl the other methods we have mentioned. If it be allied, Which is the propereft time for thefe ftudies ? the anfwer is, That nature ftiould be ftudied at all times, becaufe Ihe is to be reprefented at all fea¬ fons ; but autumn yields the moft plentiful harveft for her fine effedts: the mildnefs of that leafon, the beauty of the Iky, the richnefs of the earth, and the variety of objedfts, are powerful inducements with the painter to make the proper inquiries for improving his genius and perfecting his art. But as we cannot fee or obferve every thing, it is very commendable to make ufe of other mens lludies, and to look apon them as if they were our own. Ra¬ phael fent fome young men into Greece to defign fuch things as he thought would be of fervice to him, and accordingly made ufe of them to as good purpofe as if he himfelf had defigned them on the fpot: for this, Raphael is fo far from deferving cenfurc, that he ought, on the contrary, to be commended ; as an example, that painters ought to leave no way untried for im¬ proving in their profeffions. The landfcape painter 32 X 2 may, 5826 Landfcape. may, accordingly, malce ufe of the works of all thofe ""who have excelled in any kind, in order to acquire a good manner ; like the bees, which gather their varie¬ ty of honey from different flowers. 38. General remarks on Landfcapes. As the gene¬ ral rules of painting are the bafis of all the feveral kinds of it, we muft refer the landfcape painter to them, or rather fuppofe him to be well acquainted with them. We fhall here only make fome general remarks on this kind of painting. I. Landfcape fuppofes the knowledge and pra&ice of the principal rules in perfpeftive, in order to main¬ tain probability. II. The nigher the leaves of trees are to the earth, the larger they are, and the greener ; as being apteft to receive, in abundance, the fap which nourifhes them; and the upper branches begin firft to take the rednefs or yellownefs which colours them in autumn. But it isotherwife in plants; for their flocks renew all the year round, and their leaves fucceed one another, at a confiderable diftance of time, infomuch that na¬ ture, employed in producing new leaves to adorn the flock as it rifes, does by degrees defert the under ones; which, having firfl performed their office, are the firfl that die: but this effed is more vifible in fome than in others. III. The under parts of all leaves are of a brighter green than the upper, and almoft always incline to the filverifh ; and thofe which are wind-fhaken are known from others by that colour : but if we view them from beneath, when penetrated by the fun’s rays, they dif- cover fuebja fine and lively green as is far beyond all eomparifon. IV. There are five principal things which give fpi- rit to landfcape, viz. figures, animals, waters, wind- Ihaken trees, and thinnefs of pencilling ; to which add fmoke, when there is occafion to introduce it. V. When one colour predominates throughout a landfcape, as one green in fpring, or one red in au¬ tumn, the piece will look either As of one colour, or elfe as unfinifhed. We have feen many of Bourdon’s landfcapes, which, by handling the corn one way throughout, have loft much of their beauty, though the fituations and waters were very pleafant. The in¬ genious painter muft endeavour to corred, and, as they fay, redeem the harffi unfightly colouring of win¬ ter and fpring by means of figures, waters, and build¬ ings ; for fummer and autumn fubjeds are of them- felves capable of great variety. VI. Titian and Carrache are the beft models forin- fpiring good tafte, and leading the painter into a good track, with regard to forms and colours. He muft ufe all his efforts to gain a juft idea of the principles which thofe great men have left us in their works; and to have his imagination filled with them, if he would advance by degrees towards that perfedion which the artift Ihould always have in view. VII. The landfcapes of thefe two mafters teach us a great many things, of which difeourfe can give us no exad idea,nor any general principle. Which way, for example, can the meafures of trees in general be determined, as we determine thofe of the human bo¬ dy ? The tree has no fettled proportions^; mofl of its beauty lies in the contrail of its branches, an unequal diftribiition of boughs, and, in fliort, a kind of whim- Part II. fical variety, Which nature delights in, ahd of which Landfcape thelpainter becomes a judge whett be has thoroughly ' ^ relilhed the works of the two maftefs aforefaid. But we muft fay, in Titian’s praife, that the path he (truck out is the fureft ; becanfe he has exadly imitated na¬ ture in its variety with an exquifite tafte, and fine co¬ louring : whereas Carrache, though an able artift, has not, more than others, been free from manner in his landfcapes. VIII. One of the greateft perfedions of landfcape, in the variety it reprefents, is a faithful imitation of each particular charader: as its greateft fault is, a licentious pradice, which brings us to do things by tote. IX. Among thofe things which are painted prac¬ tically, we ought to intermix fome done after na¬ ture, to induce the fpedator to believe that all arc fo. X. As there are ftyles of thought, fb there-are al- fo ftyles of execution. We have handled the two re¬ lating to thought, viz. the heroic and paftoral ; and find that there are two alfo with regard to execution, viz. the firm ftyle, and the polilhed ; thefe two con¬ cern the pencil, and the more or lefs ingenious way of conduding it. The firm ftyle gives life to work, and excufe for bad choice: and the polilhed finilhes and brightens every thing; it leaves no employment for the fpedator’s imagination, which pleafes itfelf in difeo- vering and finilhing things which it aferibes to the ar¬ tift, though, in fad, they proceed only from itfelf. The polilhed ftyle degenerates into the foft and dull, if not fupported by a good opening or fitua- tion ; but when thofe two charaders meet, the pidure is fine. Sect. III. Of Portraiture. 39. If painting be an imitation of nature, it is doubly fo in a portrait ; which not only reprefents a man in general, but fuch an one as may be dillinguilhed from all others. And as the greateft perfedion of a. por¬ trait is extreme likenefs, fo the greateft of its faults is to refemble a perfon for whom it was not made ; fince there are not in the world two perfons quite like one another. But before we proceed to the particulars which let us into the knowledge of this imitation, it is necef- fary, for fhortening this part of our fubjed, to attend to fome general propofitions. I. Imitation is the effence of painting: and good choice is to this effence what the virtues are to a man; they raife the value of it. For this reafon, it is extreme¬ ly the painter’s intereft to choofe none but good beads, or favourable moments for drawing them, and fuch pofitions as may fupply the want of a fine natural. II. There are views of the natural, more or lefs ad¬ vantageous ; all depends upon turning it well, and ta¬ king it in the favourable moment. III. There is not a Angle perfon in the world who has not a peculiar charader, both in body and face. IV. Simple and genuine nature is more proper for imitation ; and is a better choice than nature much formed, and embellifhed too artificially. V. To adorn nature too much, is doing it a violence; and the ad ion which attends it can never be free, when its ornaments are not eafy. In Ihort, in proportion as we adorn nature, we make it degenerate from itfelf, and FAINTING. Part IT. PAIN Portraiture, and bring it down to art. VI. Some means are more advantageous than others, to come at the fame end. VII. We muft not only imitate what we do fee in nature, but alfo what we may poffibly fee that is ad¬ vantageous in art. VIII. Things are valuable by comparifon; and it is only by this we are enabled to make a right judg¬ ment of them. IX. Painters eafily accuftom themfelves to their own tints, and the manner of their matters: and af¬ ter this habit is rooted in them, they view na¬ ture, not as ihe really is, but as they are ufed to paint her. X. It is very difficult to make a pi&ure, the figures of which are as big as tbe life, to have its effect near, as at a diftance. A learned picture pleafes the ig¬ norant only when it is at fome diftance ; but judges will admire its artifice near, and its effedt at a di¬ ftance. XI. Knowledge makes work pleafant and eafy. The traveller who knows his road, comes to his journey’s end with more fpeed and certainty than he who in¬ quires and gropes it out. XII. It is proper, before we begin a work, to me¬ ditate upon it, and to make a nice coloured fketch of it, for our own fatisfadion, and an help to the me¬ mory. We cannot too much refled on thefe propofitions ; and it is neceflary to be well acquainted with them, that they may prefent themfelves to our mind, of their own accord, without our being at the trouble torecalthem to our memory, when we are at work. There are four things neceflary to make a portrait perfed ; air, colouring, attitude, and drefs. 40. Of Air. The air refpeds the lines of the face, tbe head- attire, and the fize. . The lines of the face depend upon exadnefs of draught, and agreement of the parts; which all toge¬ ther muft reprefent the phyfiognomy of the perfon painted in fuch a manner, that the pidure of his body may feem to be alfo that of his mind. It is not exadnefs of defign in portraits that gives fpirit and true air, fo much as the agreement of the parts at the very moment when.the difpofition and temperament of the fitter are to be hit oflf. We fee feveral portraits which, though corredly defigned, have a cold, languilhing, and ftupid air; whilft others, lefs corred in defign, ftrike us however, at firft fight, with the fitter’s charader. Few painters have been careful enough to put the parts well together: Sometimes the mouth is fmiling, and the eyes are fad ; at other times, the eyes are cheerful, and the cheeks lank : by which means their work has a falfe air, and looks unnatural. We ought therefore to mind, that, when the fitter puts on a fmi¬ ling air, the eyes clofe, the corners of the mouth draw up towards the noftrils, the cheeks fwdI, and the eye¬ brows widen : but in a melancholy air, thefe parts have a contrary effed. The eye-brows, being raifed, give a grave and noble air; but if arched, an air of aftonilhment. Of all the parts of the face, that which contributes moft to likenefs is the nofe ; it is therefore of great moment to let and draw it well. TING. _ 5827 Though the hair of the head feems to be part of the Portraiture* drefs, which is capable of various forms, without al- tering the air of the face; yet the head-attire which one has been moft; accuftomed to creates fuch a like¬ nefs, that we fcarce know a familiar acquaintance on his putting on a periwig fomewhat different from that which he ufed to wear. It is neceffary therefore, as far as poffible, to take the air of the head-ornament, and make it accompany and fet off that of the face, if there be no reafon to the contrary. As to the ftature, it contributes fo much to likenefs, that we very often know people without feeing their face : It is therefore extremely proper to draw the fize after the fitter himfelf, and in fuch an attitude as we think fit; which was Vandyke’s method. Here let us remark, that, in fitting, the perfon appears to be of a lefs free make, through the heaving of his (boul¬ ders ; wherefore, to adjuft his fize, it is proper to make him (land for a fmall time, fwaying in the po- fture we would give him, and then make our obferva- tion. But here occurs a difficulty, which we (hall en¬ deavour to examine : “ Whether it is proper, in por¬ traiture, to corredt the defe&s of nature?” Likenefs being the effence of portraiture, it would feem that we ought to imitate defedts as. well as beau¬ ties, fince by this means the imitation will be more complete : It would be even hard to prove the contrary to one who would undertake the defence of this pofi- tion. But ladies and gentlemen do not much approve of thofe painters who entertain fuch fentiments, and put them in praQice. It is certain that fome complai- fance in this refpedt is due to them ; and there is little doubt but their pidlures may be made to referable, without difpleafing them : for the effedlual likenefs is a juft agreement of the parts that are painted with thofe of nature ; fo that we may be at no lofs to know the air of the face, and the temper of the perfon, whofe pidlure is before us. All deformities, therefore, when the air and temper may be difeovered without them, ought to be either corredled or omitted in womens and young mens portraits. A nofe fomewhat awry may be helped, or a (hrivelled neck, or high (boulders, ad¬ apted to good air, without going from one extreme to another. But this mull be done with great diferetion ^ for, by endeavouring to correct nature too much, wc infenfibly fall into a method of giving a general air to all our portraits ; juft as, by confining ourfelves too much to the defefts and littlenefsof nature, we are in danger of falling into the low and taftelefs manner. But in the faces of heroes and men of rank, diftin- guiftied either by dignities, virtues, or great qualities, we cannot be too exadl, whether the parts be beauti¬ ful or not: for portraits of fuch perfons are to be (landing monuments to pofterity ; in which cafe, every thing in a pidlure is precious that is faithful. But af¬ ter whatever manner the painter acquits himfelf in this point, let him never forget good air nor grace ; and that there are, in the natural, advantageous moments for hitting them off. 41. Of Colouring.—Colouring, in portraiture, is an effufion of nature, difeovering the true tempers of per¬ fons; and the temper being eflential to likenefs, it ought to be handled as exadlly as the delign. This part is the more valuable, as it is rare and difficult to hit. A great many painters have come to a likenefs by ftrokes and outlines 5 5828 PAIN Portraiture, outlines; but certainly they are few who have fhewn in colours the tempers of perfons. Two points are neceffary in colouring ; exaftnefs of tints, and the art of fetting them off. The former is acquired by pra&ice, in examining and comparing the colours we fee in life with thofe by which we would imitate it: and the art of thofe tints confifts in know¬ ing what one colour will produce when fet by another, and in making good what either diftance or time may abate of the glow and frelhnefs of the colours. A painter who does nothing more than what he fees, will never arrive at a perfeft imitation ; for -though his work may feem, on the eafel, to be good to him, it may not appear fo to others, and perhaps even to him- felf, at a diftance. A tint which, near, appears dif- joined, and of one colour, may look of another at a diftance, and be confounded in the mafs it belongs to. If you would have your work, therefore, to pro¬ duce a good effedt in the place where it. is to hang, both the colours and lights muft be a little loaded ; but learnedly, and with diferetion. In this point confult Titian, Rubens, Vandyke, and Rembrandt’s methods ; for indeed their art is wonderful. The tints ufually require three times of obfervation. The firft is^at the perfon’s firft fitting down, when he has more fpirit and colour than ordinary ; and this is to be noted in the firft hour of his fitting. The fecond is when, being compofed, his look is as ufual; which is to be obferved in the fecond hour. And the third is when, through tirefomenefs by fitting in one pofture, his colour alters to what wearinefs ufually creates. On which account, it is beft to keep to the fitter’s ufual tint, a little improved. He may alfo rife, and take fome turns about the room, to gain frefh fpirits, and fliake off or prevent tirefomenefs. In draperies, all forts of colours do not fuit all forts of perfons. In mens portraits, we need only obferve great truth, and great force : but in womens there muft alfo be charms ; whatever beauty they have muft ap¬ pear in a fine light, and their blemilhes muft by fome means or other be foftened. For this reafon, a white, lively, and bright tint, ought never to be fet off by a fine yellow, which would make it look like plafter; but rather by colours inclining to green, blue, or grey, or fuch others as, by their oppofition, may make T;he tint appear more fleftiy than ufual in fair women. Van¬ dyke often made a fillemot-coloured curtain for his ground ; but that colour is foft and brown. Brown women, on the other hand, who have yellow enough in their tints to fupport thecharafter of flefhinefs, may very well have yellowifh draperies, in order to bring down the yellow of their tints, and make them look the frefher; and, near very high-coloured and lively carnations, linen does wonders. In grounds, two things are obfervable; the tone and the colour. The colour is to be confidered in the fame manner as thofe of draperies, with refped. to the head. The tone muft be always different from the mafs it fupports, and of which it is the ground, that the ob- jedts coming upon it may not feem' tranfparent, but folid and raifed. The colour of the hair of the head ufually determines the tone of the ground ; and when the former is a bright chefnut, we are often embarraf- fed, unlefs helped by means of a curtain, or fome ac- -cident of the claro obfeuro, fuppofed to be behind, or TING* Part II. unlefs the ground is a Iky. Portraiture^ We muft further obferve, that where a ground is neither curtain nor landfcape, or fuch like, but is plain and like a wall, it ought to very much party-coloured, with almoft imperceptible patches or ftains; for, be- fides its being fo in nature, the pi&ure will look the more grand. 42. Of Attitude, or Pcfure. Attitudes ought to fuit the ages and qualities of perfons and their tempers. In old men and women, they fhould be grave, maje- ftic, and fometimes bold: and generally, in women, they ought to have a noble fimplicity and modeft cheerfulnefs; for modefty ought to be the chara&er of women ; a charm infinitely beyond coquetry ! and indeed coquettes themfelves care not to be painted fuch. Attitudes are of two kinds; one in motion, the other at reft. Thofe at reft may fuit every perfon : but thofe in motion are proper for young people only, and are hard to be expreffed ; becaufe a great part of the hair and drapery muft'be moved by the air ; mo¬ tion, in painting, being never better expreffed than by fuch agitations. The attitudes at reft muft not appear fo much at reft as to feem to reprefent an in¬ active perfon, and one who fits for no other purpofe but to be a copy. And though the figure that is re- prefented be at reft, yet the painter, if he thinks fit, may give it a flying drapery, provided the feene or ground be not a chamber or clofe place. It is above all things neceffary that the figures which are not employed (hould appear to fatisfy the fpeCta- tor’s curiofity ; and for this purpofe fhew themfelves in fuch an aftion as fuits their tempers and conditions, as if they would inform him what they really were: and as moft people pretend to fincerity, honefty, and greatnefs of mind, we muft avoid, in attitudes, all manner of affe&ation ; every thing there muft appear eafy and natural, and difeover more or lefs fpirit, noblenefs, and majefty, in proportion to the perfon’s character and dignity. In a word, the attitudes are the language of portraits ; and the Ikiiful painter ought to give great attention to them. But the beft attitudes are fuch as induce the fpedta- tor to think that the fitter took a favourable opportu¬ nity of being feen to advantage, and without affecta¬ tion. There is only one thing to be obferved with regard to womens portraits, in whatever attitude they are placed ; which is, that they fway in fuch a man¬ ner as to give their face but little fhade ; and that we carefully examine whether the lady appear moft beau¬ tiful in a fmiling or in a ferious air, and conduCt our- felves accordingly. Let us now proceed to the next article. 43. Of Praftice in Portraiture. According to De Piles, portraiture requires three different fittings and operations; to wit, dead-colouring, fecond-colouring, and retouching or finilhing. Before the painter dead- colour, he muft attentively confider what afpeft will beft fuit the fitter, by putting him in different pofi- tions, if we have not any fettled defign before us: and when we have determined this, it is of the laft confe- quence to put the parts well together, by comparing always one part with another ; for not only the por¬ trait acquires a greater likenefs when well defigned, but it is troublefome to make alterations at the fecond fitting, when the ardft muft only think of painting, Part II. PAIN Portraiture, that is, of dlfpofing and uniting his colours. — Experience tells us, that the dead-colouring ought to be clean, becaufe of the flope and tranfparency of the colours, efpecially in the (hades: and when the parts are well put together, and become clammy, they mud be judicioufly fweetened and melted into each other; yet without taking away the air of the pic¬ ture, that the painter may have the pleafure of finifh- ing it, in proportion as he draws. But if fiery geni- ufes do not like this method of fcumbling, let them only mark the parts (lightly, and fo far as is neceffary for giving an air. In dead-colouring, it is proper to put in rather too little than too much hair about the forehead ; that, in finifiu'ng, we may be at liberty to place it where we pleafe, and to paint it with all poffible foftnefs and de¬ licacy. If, on the contrary, you (ketch upon the fore¬ head a lock which may appear to be of a good tafte, and becoming the work, you may be puzzled in fi- nifiiing it, and not find the life exa&ly in the fame pofition as you would paint it. But this obfervation is not meant for men of (kill and confummate experi¬ ence, who have nature in their heads, and make her fubmit to their ideas. The bufinefs of the fecond fitting is, to put the co¬ lours well in their places, and to paint them in a man¬ ner that is fuitable to the fitter and to the effedl we propofe : But before they are made clammy, we ought to examine afrelh whether the parts are rightly placed, and here and there to give fome touches towards like- nefs, that, when we are allured of it, the work may go on with greater fatisfa&ion. If the painter under- ftands what he is about, and the portrait be jufily de- figned, he ought as much as poffible to work quick ; the fitter will be better pleafed, and the work will by this means have the more fpirit and life. But this rea- dinefs is only the effed of long ftudy and experience ; for we may well be allowed a confiderable time to find out a road that is eafy, and fuch as we mud often tra¬ vel in. Before we retouch or finifh, it is proper to termi¬ nate the hair, that, on finifhing the carnations, we may be abler to judge of the effed of the whole head. If, at the fecond fitting, we cannot do all we in¬ tended, which often happens, the third makes up the lofs, and gives both fpirit, phyfiognomy, and cha- rader. If we would paint a portrait at once, we mud load the colouring; but neither fweeten, nor drive, nor very much oil it : and if we dip the pencil in varniffi as the work advances, this will readily enable us to put co¬ lour on colour, and to mix them without driving. The ufe and fight of good pidures give greater light into things than words can exprefs: What hits one artid’s underdanding and temper may be difa- greeable to another’s; and almod all painters have taken different ways, though their principles were of¬ ten the fame. We are told that a friend of Vandyke’s having ob- ferved to him how little time he bedowed on his por¬ traits, Vandyke anfwered, “ That at fird he worked hard, and took great pains, to acquire a reputation, and alfo to get a fwift hand, againlt the time he ffiould work for his kitchen.” Vandyke’s cudom is faid to have been this: He appointed both the day and hour TING. 5S2g for the perfon’s fitting, and worked net above an Portraitnrji hour on any portrait, either in rubbing in orfinifliing; fo that as foon as his clock informed him that the hour was out, he rofe up, and made a bow to the fitter, to fignify, that he had done enough for that day, and then appointed another hour fome' other day ; whereupon his fervant came to clean his pencils, and brought a freffi pallet, whild he was receiving another fitter, whofe day and hour he had before ap¬ pointed. By this method he worked on feveral pic¬ tures the fame day, with extraordinary expedition. After haying lightly dead-coloured the face, he put the fitter into fome attitude which he had before con¬ trived ; and on a grey paper, with white and black crayons, he defigned, in a quarter of an hour, his (hape and drapery, which he difpofed in a grand manner and an exquifite tade. After this, he gave the drawing to the (kilful people he had about him, to paint after the fitter’s own cloaths, which, at Van¬ dyke’s requed, were fent to him for that purpofe. When his difciples had done what they could to thefe draperies, he lightly went over them again ; and fo, in a little time, by his great knowledge, difplayed the art and truth which we at this day admire ill them. As for hands, he had in his houfe people of both fexes* whom he paid, and who ferved as models. This conduft of Vandyke, however, is mentioned rather to gratify the reader’s curiofity, than to excite his imitation ; he may choofe as much of it as he pleafesand as fuits his own genius, and leave the red. We mud obferve by the way, that there is nothing fo rare a» fine hands, either in the defign or colouring. It is therefore convenient to cultivate, if we can, a friendffiip with fome women who twill take pleafure in ferving for- a copy: The way to win them is, to praife their beauty exceedingly. But if an oppor¬ tunity ferves of copying hands after Vandyke, it mud not be let (lip ; for he drew them with a furprifing delicacy, and an admirable colouring. It is of great fervice to copy after the manners which come neared to nature; as are thofe of Titian: and Vandyke. We mud, at fuch times, believe them to be nature itfelf; and, at fome didance, confider them as fuch, and fay to ourfelves—W/;at colour and tint Jhall I ufe for fuch a part ? And then, coming near the picture, we ought to examine, whether wu are right, or not; and to make a fixed rule of what we have difeovered, and did not praftife before with¬ out uncertainty. It is recommended, before we begin colouring, to catch the very fird moments, which are commonly the mod agreeable and mod advantageous, and to keep them in onr memory for ufe when we are finilhing: for the fitter, growing tired with being long in the fame place, lofes thofe fpirits, which, at his fird fit¬ ting down, gave beauty to the parts, and conveyed to the tint more lively blood, and a freffier colour. In (hort, we mud join to truth a probable and advan¬ tageous poffibility, which, far from abating likenefs, ferves rather to fet it off. For this end, we ought to begin with obferving the ground of a tint, as well what it is in lights as in (hades; for the (hades are only beautiful as they are proportioned to the light. We mud obferve if the tint be very lively ; whether it partake of yellownefs, and where that yellownefs is placed s 5B30 PAIN Decorations placed; becaufc ufually, towards the end of the fit- ting, fatigue diffufes a general yellownefs, which makes us forget what parts were of this colour, and what were not, unlefs we had taken due notice of it before. For this reafon, at the fecond fitting, the colours muft be every where readily clapped in, and fuch as appear at the firtt fitting down ; for thefe are always the fineft. The fureft vyay to judge of colours is by compari* fon ; and to know a tint, nothing is better than to compare it with linen placed next it, or elfe placed next to the natural objed, if there is occafion. We fay this only to thofe who have little praftifed nature. The portrait being now fuppofed to be as much finilhed as you are able, nothing remains, but, at fome reafonable diftance, to view both the pid^ure and fitter together, in order to determine with certainty, whether there is any thing ftill wanting to perfect the work. Sect. IV. Of Theatric Decorations; the Defigns for Furniturey Embroideryy GarriageSy /vr- torium, at the wed end of the town, are at prefent ai¬ med annihilated. It was fuppofed to be vaulted un¬ derneath. The inhabitants of Paifley, in 1746, were compu¬ ted at no more than 4000 : but from a very accurate furvey which has jud been made, the number of fa¬ milies in Paifley and fuburbs is found to be 3723 ; and allowing 4! perfons to each family, the number of in¬ habitants will be 16,753. Paifley is now the fird manufaAuring town in Scot¬ land, and is greatly celebrated on account of fotne of its branches. The manufaftory of filk gauze, in this refpeQ, fird claims our notice. This branch is brought here to the utmod perfe&ion, and is wrought to an amazing variety of patterns. It has been jud compu¬ ted, that there have been no lefs than 5000 weavers employed in Paifley and in the country adjacent, in this branch, lad year (1781); and the number of wind¬ ers, warpers, clippers, and others neceffary in other parts of the filk-manufadlure, has been likewife com¬ puted to be no lefs than 5000. Each loom will pro| duce in average value 701. yearly ; the whole will then be 350,000 1. The linen branch is likewife carried on here to a very confiderable amount, particularly the manufac¬ ture of lawns; and vad quantities of foreign yarn are an- Paifley nually imported from France, Germany, &c. for this S branch, befides what is made of our home-manufa&u- Palace- red yarn. It appears from the damp-mader’s books, that from id November 1780 to id November 1781, there were damped at Paifley no lefs than 1,248,843 yards, value 105,930!. 19 s. io£. The making of white ditching thread was introduced into this town a- bout 50 or 60 years ago. A gentleman in this place lately difeovered the method of making what is called glazed ’white-thread, to as great perfedion as that made by Mr Leland and Son, London. The value of this branch is computed at about 60,0001. annually. There are alfo feveral manufadures of a more local nature. There are three of hard-foap and tallow-candles, and one of black-foap. The candles, efpecially the mould¬ ed ones, are reckoned the bed and mod elegant that have been made in Scotland ; and great quantities is fent into England, to America, and to the Wed In¬ dies. The annual amount of thefe lad branches are edimated at nearly 20,000 1. There are alfo two or three tan-works, and a porter brewery, in town ; and in the neighbourhood there is d coperas work, a calli- co printing work, and two works for the cotton fpin* ning manufadory. The river on which Paifley dands runs from fouth to north; and falls into Clyde, after it has joined the conflux of the rivers Grief and Black-Cart at Inchin- nan bridge, about three miles below the town. At fpring-tides, veffels of 40 tons burthen come up to the quay. The communication by water is of great im¬ portance to the inhabitants : for in this way they are frequently ferved with fifli of different kinds, and can fend their goods and manufadures to Port-Glafgow and Greenock, and to Glafgow likewife; and now, when the canal is finiflied, they have alfo a communi¬ cation with the frith of Forth. Paifley was created a burgh of barony in the year 1488; and the affairs of the community are managed by three bailies, of which the elded is commonly in the com- mifiionofthe peace, a treafurer, a town-clerk, and 17 counfellors, who are annually eleded upon the fird Mon¬ day after Michaelmas. It gives the title of baron to the earls of Abercorn ; the fird of whom was a young¬ er fon of the Due de Chatellerault. The Hack-look of Paijley, frequently mentioned in Scottilh hiftory, was a chronicle of the public affairs and remarkable events, kept by the monks who refided in the monadery al¬ ready mentioned. It agreed in every material fad with the Scot's-chronicon of Fordun ; and is by many thought to be the fame performance. PAITA, a fea-port of America, in Peru, and in the audience of Quito. The town confids of about 200 houfes but one dory high; and the walls are made of fplit cane and mud, and the roofs only a covering of leaves. The only defence of Paita is a fort without ei¬ ther ditch or out-work ; but it is furrounded by a brick wall of little or no drength, on which are mounted eight pieces of cannon. Commodore Anfon got pof- fefiion of this fort in 1741; and took and burnt the town, becaufe the governor refufed to ranforo it. W. Long. 80. 5. S. Lat. 5. 5. PALACE, PalAtium, a name generally given to the dwelling-houfes of kings', princes, and other great perfonagesj and taking different epithets, according to the PAL [ 5S33 ] PAL Palace the quality of the inhabitants, as imperial palace, royal li palace, pontifical palace, cardinal palace, ducal palace. Palate. epifcopal palace, &c. Palace-See Marshalsea. PALiEMON, or Melicertes, in fabulous hiftory, a marine god, was the fon of Athatnas, king of Thebes and Ino. The latter, fearing the rage of the king her hufband, took Melicertes in her arms, and leaped with him into the fea, when they were both changed into marine deities ; the mother under the name Leucothea, fuppofed by fome to be the fame with Aurora; and her fon under that of Pale?/,on, or Portunus, a god who prefided over fca-ports. Paufanias fays, that Melicer¬ tes was faved on the back of a dolphin, and his dead body thrown on the ifthmus of Corinth, where Sify- phus, his uncle, who reigned in that city, inftituted to his honour the Ifthmian games. Paljemon Rhemmius), a Latin grammarian, born at Vicenza, was the fon of {lave. He taught at Rome with great applaufe under Tiberius and Clau¬ dius, and Juvenal mentions him with praifes. We have only fome fragments of his works. PALjEFAPPIOS, (Strabo, Virgil, Pliny), a town of Cyprus, where Hood a temple of Venus; and an ad¬ joining town called Nea Paphos; where St Paul ftruck Elymas blind, and converted the proconful Sergius Paulus. PALAESTRA, in Grecian antiquity, a public build¬ ing, where the youth exercifed themfelves in wreftling, running, playing at quoits, &c. PAL-ESTROPHYLAX, was the dire&or of the palaeftra, and the exercifes performed there. PALAMEDIA, in ornithology, a genus belong¬ ing to the order .of grallas. The bill is conical, the fu- perior mandible being crooked; and the feet have three divided toes. There are two fpecies, both natives of Brafil. PAL ARIA, among the Romans, a kind of exercife performed at a flake by the foldiers. The flake being fixed in the ground, and fix feet high above it, the young undifciplined foldiers advanced againft it, armed with a hurdle and cudgel, inftead of a fword and (hield, and went through all the rules of attack and defence, as if aftually engaged with an adverfary. Sometimes they flood at a diftance, and attacked with miffive wea¬ pons; at the fame time ufing all the requifite motions for defending themfelves, and warding off what might be thrown againft them. PALATE, in anatomy, the flefh that compofes the roof, or the upper and inner part, of the mouth. The palate has much the fame ftru£ture with the gums; but it has alfo a greatinumber of glands, difco- vered fo early as the time of Fallopius: thefe are prin¬ cipally fituated in the hinder part near the uvula, where it is pendulous, in the manner of a curtain, which part is called the velum, or claujlrum, of the palate. The glands fituated particularly in this part, fecrete a mu¬ cous fluid, ferving to lubricate the mouth and throat, and to facilitate deglutition : they have a great num¬ ber of apertures there for the difcharge of this humour into the mouth. The great ufes of this membrane are to defend the bones of the palate from corrupting; and for prevent- ing, by its clauftrum or velum, the things to be fwal- kwed from getting up into the noijrils. PALATINATE, a province or figniory, poiTeiTed Palatinafc by a palatine. ’*■" Palatinate of the Rhine, a province of Germany, divided into two parts by the Rhine, called the Upper and Lower Palatinate. The formier lies in the circle of Bavaria, and belongs to the elector thereof; but the latter, in the circle we are now treating, belongs to the ele&or Palatine. The latter part is bounded fo the eaft by the county of Katzenellnbogen, the arch- bilhopric of Mentz, the bifhopric of Worms, and part of the territory of the Tuetonic order in Franco¬ nia ; to the weft, by Alface, the duchy of DeuxpontS, the county of Sponheim, the duchy of Simmern, and certain diftridts of the deflorate of Mentz ; to the fouth, by the duchy of Wurtemberg and the bilhopric of Spire ; and to the north, by a part of archbifhoprio of Mentz and the county of Katzenellnbogen. It contains 41 towns, befides feveral boroughs ; and its greateft extent is about 80 miles. The air is health¬ ful, and the foil fruitful in corn, pafturage, wine, to¬ bacco, and all forts of pulfe and fruks, particularly walnuts, chefnuts, and almonds. This country alfo breeds abundance of cattle, and is well watered by the Neckar, the Nahe, and the Rhine. In the laft of thefe, near Germerfheim and Selz, is found gold 5 the exclufive right of fearching for which is farmed out by theeleftor. The ftate of religion hath varied greatly here fince the Reformation, Lutberanifm and Calvi- nifm having been uppermoft by turns, till the eleflo- tate devolved to the Popifh branches of the family, when Popery, with all its fuperftition and mummery, was eftabliflied anew : fo that the Proteftant religion is now on a very precarious footing in the Palatinate, though moft of the natives are (till of that perfuafion : but the two fefts of Proteftants, namely, the Luthe¬ rans and Calvinifts, have greatly contributed to then- own ruin, by their mufual jealoufy and animofity, be¬ ing no lefs rancorous againft one another than againft their common adverfaries the Papifts. The Lutherans reckon themfelves 50,000 ftrong, and are pofftfied of about 85 churches ; but not one half of their preach¬ ers and fchoolmafters have a competent maintenance. The number of Calvinifl clergy here is eftimated at 500, and that of the Roman Catholics at 400. Be¬ fides fchools and Jefuits colleges in this country, there is one univerfity, namely, that of Heidelberg; but there is very little trade in it except in wine. Authors are divided about the origin of the name Palatines, or Pfalzgraves, as the Germans call them ; but it feems molt likely to be derived from the palatia, or palaces, which the old FrankHh and German kings and Roman emperors were poflefled of in different parts of the country, and over which they appointed fupreme ftew- ards or judges, who were called Palatines or Pfalz¬ graves. The countries where thefe Palatines kept their courts were, from them, called Palatinates j which name came at laft to be appropriated, by way of eminence, to this country, as being the moft con- fiderable of them. The ancient eleftoral line failing in 1685, the deflorate devolved to Philip-William Duke of Neuburg ; and upon the death of his fecorid fon Charles-Philip, to the prince of Sulzbacb. . This eleflorhas the title of arch-treafurer of the empire, as well as the eleflor of Brunfwic-Luneburgh, and is the fifth in rank among the fecular deflora. He is 32 Y 2 alfo PAL [ 5834 ] PAL Palatine, alfo one of the vicars of the empire alternately with " the eledtor of Bavaria, and enjoys many other prero¬ gatives. In his own dominions, he difpofes of all va¬ cant benefices ; but allows the ecclefiaftical council, compofed of two clergymen and two laymen, to pre- fent two candidates, of which he choofes one. He is alfo mafter of all the tithes in his dominions; but he either grants them to the clergy, or falaries in lieu of them, out of the revenues of the church. His title is Pfalzgrave of the Rhine ; archtreafurer and ele&or of the holy Roman empire; duke in Bavaria, Juliers, Cleve, and Berg; prince of Mors; marquis of Ber¬ gen-op-Zoom ; count of Veldens, Sponheim, the Mark, and Ravenlberg; and lord of Ravenllein. His quota to the army of the empire is 30 horfe, and 138 foot, or 914 florins monthly. To the chamber of Wetzlar he contributes, each term, 404 rix-dollars, 82 kruit- zers. There is an order of knighthood in this coun¬ try, viz. that of St Hubert ; the badge of which is a quadrangular crofs pendant to a red ribbon, with a liar on the breaft. The whole of the eleftor’s reve¬ nue, arifing from the Palatinate, the duchies of Berg and Juliers, the feigniory of Ravenftein, and the du¬ chies of Neuburg and Sultzbach, hath been eftimated at about 300,000 1. per annum. The military efta- blilhment confifts of feveral regiments of horfe and foot, befides the horfe and Swifs life-guards. All the dif¬ ferent courts and councils, ufuaj in other countries for the different departments of government, are alfo to be found here. PALATINE, or Count Palatine, a title an¬ ciently given to all perfons who had any office or em¬ ployment in the prince’s palace ; but afterwards con¬ ferred on thofe delegated by princes to hold courts of juftice in the provinces; and on fuch among the Lords as had a palace, that is, a court of juftice, in their own houfes. * Palatine in England.—Chefter, Durham, and Lancafter, are called counties palatine. The two former are fuch by prefcription, or immemorial cu- llom ; or, at lead as old as the Norman conqueft : the latter was created by king Edward* III. in favour of Henry Plantagenet, firft earl and then duke of Ldn- cafter ; whofe heirefs being married to John of Gaunt the king’s fon, the franchife was greatly greatly en¬ larged and confirmed in parliament, to honour John of Gaunt himfelf, whom, on the death of his father-in- law, the king had alfo created duke of Lancafter. Counties-palatine are fo called a palatio ; becaufe the owners thereof, the earl of Chefter, the bifhop of Dur¬ ham, and the duke of Lancafter, had in thofe coun¬ ties Jar# regolia, as fully as the king hath in his palace; regaJem potejlatem in omnibus^ as Brafton expreffes it. They might pardon treafons, murders, and felonies ; they appointed all judges and juftices of the peace ; all writs and indidments ran in their names, as in other counties in the king’s; and all offences were faid to be done againft their peace, and not, as in other places, contra pacem domini regis. And indeed by the ancient law, in all peculiar jurifdidions, offences were faid to be done againft his peace in whofe court they were tried; in a court-leet, contra pacesn domini; in the court of a corporation, contra pacem ballivorum in the fheriff’s court or lourn, contra pacem vice- eomitis. Thefe palatine privileges (fo (tmilar to the regal independent jurifdi&ions ufurped by the great Palatine, barons on the continent during the weak and infant “—' ftate of the firft feodal kingdoms in Europe), were in all probability originally granted to the counties of Chefter and Durham, becaufe they bordered upon enemies countries, Wales and Scotland; in order that the owners, being encouraged by fo large an authority, might be the more watchful in its defence ; and that the inhabitants, having juftice adminiftered at home, might not be obliged to go out of the county, and leave it open to the enemy’s incurfions. And upon this account alfo there were formerly two other coun¬ ties palatine, Pembrokelhire and Hexhamlhire, the latter now united with Northumberland: but thefe were abolifhed by parliament, the former in 27 Hen. VIII. the latter in 14 Eliz. And in 27 Hen. VIII. likewife, the powers before mentioned of owners of counties-palatine were abridged ; the reafon for their countinuance in a manner ceafing: though ftill all writs are witneffed in their names, and all forfeitures for treafon by the common law accrue to them. Of thefe three, the county of Durham is now the only one remaining in the hands of a fubjetff. For the earldom of Chefter, as Camden teftifies, was united to the crown by Hen. III. and has ever fince given title to the king’s eldeft fon. And the county palatine, or duchy, of Lancafter was the property of Henry of Bolingbroke, the fon of John of Gaunt, at the time when he wrefted the crown from king Richard II. and affumed the title of Hen. IV. But he was too prudent to fuffer this to be united to the crown ; left, if he loft one, he (hould lofe the other alfo. For, as Plowden and Sir Edward Coke obferve, “ he knew he had the duchy of Lancafter by fure and indefeafible title, but that his title to the crown was not fo affured; for that after the deceafe of Richard II. the right of the crown was in the heir of Lionel duke of Clarence, fecond fon of Edward III.; John of Gaunt, father to this Henry IV. being but the fourth fon.” And therefore he procured an aft of parliament, in the firft year of his reign, ordaining that the duchy of Lancafter, and all other his heredi¬ tary eftates, with all their royalties and franchifes, fhoulcPremain to him and his heirs for ever; and fhould remain, defcend, be adminiftered, and governed, in like manner as if he never had attained the regal- dig¬ nity : and thus they defcended to his fon and grand- fon, Henry V. and Henry VI.; many new territories and privileges being annexed to the duchy by the former. Henry VI. being attainted in 1 Edward IV. this duchy was declared in parliament to have become foreited to the crown, and at the fame time an aft was made to incorporate the duchy of Lancafter, to continue the county palatine (which might otherwife have determined by the attainder), and to make the fame parcel of the duchy: and, farther, to veft the whole in king Edward IV. and his heirs, kings of England, for ever ; but under a feparate guiding and governance from the other inheritances of the crown. And in 1 Hen. VII. another aft was made, to refume fuch part of the duchy lands as had been difmem- bered from it in the reign of Edward IV. and to veft the inheritance of the whole in the king and his heirs for ever, as amply and largely, and in like manner, form, and condition, feparate from the crown of Eng- PAL [ 5835 ] PAL Palatine land and pofleflion of the fame, as the three Henries „ II. and Edward IV. or any of them, had and held the JLal.e.a,rlus:- fame. The ifle of Ely is not a county-palatine, though fometimes erroneoufly called fo, but only a royal franchife : the birtiop having, by grant of king Henry the firft, jura regalia within the ifle of Ely ; whereby he exercifes a jurifdi&ion over all caufes, as well cri¬ minal as civil. Palatine Games, in Roman antiquity, games in- flituted in honour of Auguftus by his wife Livia, after he had been enrolled among the gods. They were celebrated in the palace, and were confirmed by the fucceeding emperors. PALATINUS mons, or Palatium, the firft moun¬ tain of Rome occupied by Romulus, and where he fixed his refidence and kept his court, as did Tullus Hoftilius, Auguftus, and all the fucceeding emperors: and hence it is that the relidence of princes is galled palatium. The reafon of the name is varioufly aflign- ed. To the eaft it has the Mons Ccelius, to the fouth the Aventine, to the weft the Capitoline, and to the north the Forum.—Palatinus, the furname of Apollo from this place; where Auguftus built a temple to that god, adorned with porticos and a library, ( Horace). PALATIUM, (anc. geog.) a place in the territory of Reate, diftant from it 25 ftadia. Dionyfius Hali- carnafleus reckons it one of the firft towns of the Aborigines, and from it Varro accounts for the name of the Mans Palatinus ; namely, that a colony from Pa¬ latium fettled there. Palatium (Pliny), Pallantium (Paufanias), Palan- team (Livy) ; Pallanteum (Solinus). This laft is the true writing ; the great grandfather of Evander, from whom it took its name,, being called Pallas, not Palas: A town of Arcadia, which concurred to form Mega¬ lopolis (Paufanias). From it the Palatium, or Mons Palatinus, takes alfo its name, according to Virgil and Pliny. Palatium Dioclejtani; the villa of Dioclefian, near Salonas, where he died, (Eufebius). Afterwards cal¬ led Spalatum; which rofe to a confiderable city from the ruins of Salonse; fituate in Dalmatia on the Adri¬ atic. Now Spalatto, or Spaletro.

He gained the efteem of the men of wit and learning of his time by a noble poem on the immorta¬ lity of the foul. He was appointed profeflbr of po¬ lite literature at Sienna; where his tranquillity was di- llurbed by contefts with an envious colleague, and by the malicious afperfions of his enemies ; againft which, Palengia however, his eloquence proved always a fufficient de- (1. fence. At laft he left Sienna, and accepted the invi- tation of the magiftrates of Lucca, who gave him fe- veral marks of their efteem, and fettled a confiderable ftipend upon him. Some years after, he removed to Milan ; where he was feized by order of Pope Pius V. and carried to Rome. He was convidted of having fpoken in favour of the Lutherans, and againft the in- quifition ; and therefore was condemned to be burnt. This fentence was executed in 1566. He wrote feve- ral pieces in verfe and profe ; of which the one above- mentioned is the moft efteemed. PALENCIA, a town of Spain, in the kingdom of Leon, with a rich archbilhop’s fee.

As to the name of Judea, it did not begin to receive that till after the return of the Jews from the Babylo- nifh captivity, though it had been ftyled long before the kingdom of Judah, in oppofitionr to that of Ifrad, which revolted from it under Jeroboam, in the reign of Rehoboam the fon of Solomon. But after the return, the tribe of Judah, the only one that made any figure, fettling at Jerufalem, and in the countries adjacent, quickly gave its name to the whole territory. By pro¬ fane authors it was called by many different names ; fach as Syria, Paleftina Syria, Ctelefyria, Iduma, I- dumasa, and Phoenicia or Phoenice ; but thefe are fup- pofed only to have been given out of contempt to the Jewifli nation, whom they looked upon as unworthy of any other name than what diftinguifhed the mofi ob- feure parts of the neighbouring provinces. That part of the country which was properly called the Land of Promife, was inclofed on the weft by the Mediterranean ; on the eaft by the lake Afphaltites, the Jordan, and the fea of Tiberias or of Galilee, and the Samachonite lake ; to the north it had the moun¬ tains of Libanus, or rather of Antilibanus, or the pro¬ vince of Phoenicia ; and to the fouth, that of Edom or Idumea, from which it was likewife parted by another ridge of high mountains. The boundaries of the other part, which belonged to the two tribes and an half beyond the river Jordan, are not fo eafily defined, as well as thofe of the conquefts made by the more pro- fperous kings of the Jews. AH that can be faid with any probability is, that the river Arnon was the firft northern boundary on that fide; and with refpedt to thofe on this fide the Jordan, there is a confiderable difagreement between the Hebrew and Samaritan ver- fions of the Pentateuch. The extent of this country is likewife varioufly fet¬ tled by geographers ; fome giving it no more than 170 or 180 miles from north to fouth, and 140 in breadth where broadeft, though not much above half that breadth where narrowed. But from the lateft and moft accurate maps, it appears to extend near 200 miles in length, and about 80 in breadth about the middle, and about 10 or 15 more or lefs, where it widens or fhrinks. It reaches from 31. 30. 1033.30. N. Lat. and from 34. 50. to 37. 15. E. Long, the longed day being about 14 hours 15 minutes. Thefe hmits are fo fmall, confidering that the coun¬ try is likewife interfe&ed by high ridges or mountains, woods, deferts, &c. that many learned men have been induced to queftion what we read of its fertility and populoufuefs in former times. It mull be owned, in¬ deed, that when we compare its ancient and flourilhing ltatea when it was cultivated with the utmoft diligence by perfons well /killed in every branch of agriculture, with what it hath been fince the total extirpation of the Jews out of it, and more efpecially fince it fell into the hands of the Turks, the contrail is amazingly great: but when we confider the many evident caufes which have contributed to effect this change, and even yet conlider the nature ofthe country itfelf, we find not the leaft reafon to doubt the truth of what the facred Paleftme. hiftorians have related. Mofes deferibes the richnefs of it in the ftrongeft terms, even before the Ifraelites got poflelTion of it. It even exceeded the land of E- gypt, fo much celebrated by ancient hillorians ; efpe- ciaily in the vaft numbers of cattle which it produced ; in the quantity and excellence of its wine, oil, and fruits. With refpedl to the oil and fruits, it is plain, that the olives and oil of Canaan exceeded in goodnefs thofe of Egypt, fince the tribes fent them thither from thence ; and as for vines, Herodotus tells us, that the Egyptians had none at all, but fupplied the want of them by a liquor brewed from barley. The prefents which Jacob fent to his fon Jofeph, of honey, fpices, myrrh, almonds, and other fruits of Paldline, fhew that they mull have been much better in the land of Judea than in Egypt. The wines of Gaza, Afcalon, and Sarepta, were famous among the moft remote na¬ tions ; though it is allowed, that the wine which was made at and in the neighbourhood of Bethlehem, in great quantities, was equal at lead, if not fuperior, to any of the reft : and that of Libanus, mentioned by the prophet Hofea, was no lefs celebrated for its excellent flavour. Several circum(lances contributed to this wonderful fecundity: fuch as, the excellent temperature of the air, which was never fubjeft to excefiive heats or colds; the regularity of its feafons, efpecially the former and latter rain ; and the natural fatnefs and fertility of its foil, which required neither dunging nor manuring, and could be ploughed with a Angle yoke of oxen and a fmall kind of plough ; for the foil was, and is flill, fo (hallow, that to have gone deep into it, would rather endanger, than improve, the crop. With refpedl to the excellency of its corn, we are told, that the bread of Jerufalem was preferred above all other ; and the tribe of Afher produced the bed of both, and in grea¬ ter quantity than any other tribe : and fuch plen¬ ty was there of it, that, befides what fufficed the inhabitants, who made it their chief fuftenance, So¬ lomon, we read, could afford to fend 20,000 cors, or meafures, of it, and as many of oil, yearly, to Hiram king of Tyre ; befides what they exported in¬ to other countries. And we find, even fo late as king Herod furnamed Agrippa, the countries of Tyre and Sidon received moft of their fuftenance from his te- trarchy. As to their fruits, the grapes were delicious, finely flavoured, and very large. The palm tree and its dates were in no lefs requell ; and the plain of Jericho, among other places, was famed for the great plenty and excellence of that fruit; infomuch, that the me¬ tropolis of that territory was emphatically ftyled the city of palm-trees. But what both this plain, and other parts of Paleftine, were moft celebrated for, was, the balfam (hrub, whofe balm was efteemed fo precious a drug among the Greeks, Romans, Egyptians, and other nations, and is ftill to this day under the name of balm of Gilead. They had likewife the greateft variety of other fruit-trees in the highell perfe&ion; and which might be, in fome fenfe, ftyled perpetual, becaufe they were not only covered with a conftant verdure, but becaufe the new buds always appeared on the fame boughs before the old fruit was ripe; and of thofe buds, which were PAL [ 5837 ] PAL Paleftine. in too great quantities to be allowed to come to ma- * turity, they gathered enough to make very delightful pickles and fweatmeats, efpecially of their citrons, oranges, and apples of paradife, which laft commonly hung by hundreds in a clufter, and as big as hens eggs, and of an excellent taftc and flavour. Their vines yielded grapes twice, and fometimes three times, a-year, great quantities of which were dried up, and preferved for life, as well as their figs, plums, and other fruits. They had plenty of honey ; the very trees diftilled it; and the rocks yielded it in great quantities: but whe¬ ther that of the latter kind were there depofited by the induftrious bees, or produced fome other way, is much difputed by travellers and naturalifts. They likewife cultivated fugar-canes in great abundance; and the cotton, hemp, and flax, were moftly of their own growth and manufacture, except fome of a finer fort, that were brought to them from Egypt, and worn by thofe of the higher rank. Their vicinity to Libanus made the cedars, cypreffes, and other ftately fragrant trees, very common in moll parts of the land, but more efpecially in Jerufalem. Cattle, both large and fmall, they fed in vaft quantities; and the hilly coun¬ tries not only afforded them variety and plenty of pa- fture, but alfo of water, which defcended thence into the valleys and lowlands, and fertilized them to the degree we have feen ; befides feveral other rivers and brooks, fome of the molt remarkable of which we lhall fpeak of in their proper places. But the moft fer¬ tile pafture-grounds were thofe on each fide the river Jordan ; befrdes thofe of Sharon, or Sarona, the plains of Lydda, Jamnia, and fome others thenjuftly famed for their fecundity. Asforfilh, the rivers above-men¬ tioned, the lake of Tiberias, and the Mediterranean Sea, afforded, as they do to this day, great plenty and variety. Vaft quantities were brought to Jerufa¬ lem, on which the inhabitants moftly fubfifted; and hence one of the gates of that metropolis was, ac¬ cording to St Jerome, called the fijh-gate. The lake Afphaltites yielded fait in abundance, wherewith to feafon and preferve their fifh, which Galen affirms to have been preferable to any other for wholefomenefs, digeftion, and extenuation. In fliort, the Scripture is fo pregnant with proofs of the extraordinary richnefs and fecundity of this once happy land, and the vaft number of people that lived in it, almoft wholly upon its produdl, to fay nothing of the vaft exports of its corn, wine, oil, raifins, and other fruits, &c. that a man muft have taken a ftrange warp to infidelity, that can call it in queftion, merely on account of the melan¬ choly and quite oppofite figure it now makes under its prefent tyrannical government. But it ought to be confidered, that it was then in¬ habited by an induftrious people, who knew how to improve every inch of their land, and had made even the moft defart and barren places to yield fome kind of produ&ions, by proper care and manure: fo that the very rocks, which now appear quite bare and na¬ ked, were made to produce corn, pulfe, or pafture; being, by the induftry of the old inhabitants, covered with mould, which, through the lazinefs of the fuc- eecding proprietors, has been fince wafhed off with rains and florins. We may add, that the kings them- felves were not above encouraging all kind of agricul¬ ture, both by precept and ejample} and, above all, that they had the divine bleffing promifed to their ho- Palefling. neft endeavours and induftry; whereas it is now, and hath been long fince, inhabited by a poor, lazy, indo¬ lent people, groaning under an intolerable fervitude and all manner of difcouragements ; by which their averfion to labour and agriculture, farther than what barely ferves to fupply their prefent wants, is become, in a manner, natural and invincible. We may farther obferve, after the judicious Mr Maundrell, that there is no forming an idea of its ancient flourifhing flate, when under the influence of heaven, from what it is now under a vifible curfe. And, if we had not fe¬ veral concurring teftimonies from profane authors, who have extolled the fecundity of Paleftine, that fingle one of Julian the apoflate, a fworn enemy to Jews and Chriftians, as well as to all the facred writings, would be more than fufficient to prove it; who frequently makes mention, in his epiftles, of the perpetuity, as well as excellence and great abundance, of its fruits and product. The vifible effefts of God’s anger, which this country has felt, not only underTitus Vefpa- fian (when myriads of inhabitants were either flain, or perifhed by the moft fevere famine, peftilence, anti other calamities ; and the reft fold for flaves, into' all lands; and new colonies fent to re-people it; who found it in fuch a defolate ftate, as quite difcouraged them from reftoring it to itspriftine fruitfulnefs) ; but much more fince that emperor’s time, in the inunda¬ tions of the northern barbarians, of the Saracens, and of the more cruel and deftrudlive Chriftiaas during the holy war; and in the oppreffion it now feels under the Turkifh yoke ; may be eafily owned to be more than fufficient to have wrought the difmal change we are fpeaking of, and to have reduced the far greater part into a mere defart. Neverthelefs, if we may credit thofe who have view¬ ed it in this doleful condition, they will tell us, there are ftill fuch vifible figns of its natural richnefs and fertility, as plainly (hew, that the bare want of cul¬ ture is the main, if not the only caufe of its prefent po¬ verty and barrennefs. We (hall hint, as a further proof of this, what a learned traveller hath lately written of it from his own obfervations. “ The Holy Land,” fays Dr Shaw, “ were it as well peopled and cultivated as in former times, would Hill be more fruitful than the very bed part of the coaft of Syria and Phoenice; for the foil is generally much richer, and, all things confidered, yields a more preferable crop. Thus the cotton that is gathered in the plains of Ramah, Efdraelon, and Zabulun, is in greater efteem than what is cultivated near Sidon and Tripoli. Neither is it poffible for pulfe, wheat, or any fort of grain, to be more excel¬ lent than what is fold at Jerufalem. The barrennefs, or fcarcity rather, which fome authors may, either igno¬ rantly or malicioufly, complain of, doth not proceed from the incapacity or natural unfruitfulnefs of the country, but from the want of inhabitants, and the great averfion there is to labour and induftry in thofe few who poffcfs it. There are, befides, fuch perpe¬ tual difeords and depredations among the petty princes who (hare this fine country, that, allowing it was bet¬ ter peopled, yet there would be fmall encouragement to fow, wfien it was uncertain who (hould gather in the harveft.

PALLIUM, a word often mentioned in our old hidorians. Durandus tells us, that it is a garment made of white wool, after the following manner, viz. The nuns 6f St Agnes, every year, on the fead-day of their faint, offer two white lambs on the altar of their church, during the time they fing Agnus Dei, in a folemn mafs; which lambs are afterwards taken by two of the canons of the Lateran church, and by them iveii to the Pope’s fubdeacons, who fend them to pa- ure till fneafirig time, and then they are fhorn, ami the pall is made of their wool mixed with other white wool. The pall being thus made, is carried to the La¬ teran church, and there placed on the high altar, by the deacons of that church, on the bodies of St Peter and St Paul; and after an ufual watching, it is carried away in the night, and delivered to the fubdeacons, who lay it up fafe. And becaufe it was taken from the body of St Peter, it fignifies the plenitude of ec- clefiadical power : and therefore it was the prerogative of popes, who pretend to be the immediate fucceffors of that faint, to inveft other prelates with it; which at firft was done nowhere but at Rome, tlio’ afterwards at other places.

Nor have we any authentic hiftory of it till after the captivity of the Roman emperor. Valerian, by the Perfians. At that time it was become an opulent city, to which its fitil- ation in the vicinity of the Roman and Parthian em¬ pires greatly contributed; as the caravans, in going to or returning from the Eaft, frequented the place, rind thus rendered it a Cqnfiderable feat bf mercharidife. It enjoyed an independency till the tirne of Trajan; who, having made himfelf mafter of almoft all the Parthian empire, reduced Palmyra likewife, and it was after¬ wards accounted part of the Roman dominions. But when the defeat and captivity of Valerian had fo much weakened the empire, that the Peffians feemed to be in a fair way of becoming matters of all the ea- ftern provinces, the Palmyreniaris began to entertain thoughts of recovering their liberty. Odenathus, prince of Palmyra, fent a very refpedlful letter to Sapor on his return, accompanied with confiderable prefents; but by that haughty conqueror his letter and em- baffy were treated with the moft provoking contempt. The prefents were thrown into the" Euphrates: and to his letter Sapor replied, That hisinfolence in prefuming to write to his lord was inexcufe'able; but if he could 32 Z atone Filin "■[I ■ Palmyra. PAL [ 5840 ] P A L Palmyra, atone for it in any way, it would be by' prefentiiig ~ himfelf before the throne bound hand and foot, in to¬ ken of a confcioufnefs of his crime, and the puniihment he deferved. With this injurious treatment Odenathus was fo provoked, that he fwore either to bring down the pride of the haughty conqueror, or die in the at¬ tempt. Accordingly, having aflembled what forces he could, he fell upon the Perfians, deltroyed a number of them, took a great part of their baggage, and fome of the king’s concubines. Of the war of Odenathus with the Perfians, however, we know very little: only that though the latter were often vanquilhed, and the independency of Palmyra eftablifhed for the prefent ; yet Valerian was never releafed from his captivity, tho’ Odenathus earneftly wifhed to have the honour of ref- cuing him from his enemies. Ode’nathus enjoyed his fovereignty but a very fhort time ; being murdered by his nephew, who was foon after put to death by Zenobia the -wife of Odenathus. This lady is faid to have been poflefled of very extra¬ ordinary endowments both of body and mind, being, according to Mr Gibbon, almoft the only Afiatic woman who is recorded to have overcome the obftacles arifing from the confined fituation of the fair fex in that part of the world. Immediately on taking vengeance for the murder of her hufband, fhe alfumed the govern¬ ment, and foon ftrengthened herfelf fo much, that file refalved to fubmit neither to the Roman nor Perfian power. The neighbouring ftates of Arabia, Arme¬ nia, and Perfia, dreaded her enmity, and folicited her alliance. To the dominions of Odenathus, which ex¬ tended from the Euphrates to the frontiers of Bithynia, his widow added the inheritance of her anceftors, the populous and fertile kingdom of Egypt. The empe¬ ror Claudius acknowledged her merit, and was con¬ tent, that, while he purfued the Gothic war, (he fliould afiert the dignity of the empire in the eaft. The con- dudf, however, of Zenobia, was attended with fome ambiguity; nor is it unlikely that (he had conceived the defign of ere&ing an independent and hoftile mo¬ narchy. She blended with the popular manners of Ro¬ man princes the fiately pomp of the courts of Afia, and exa&ed from her fubjefts the fame adoration that was paid to the fucceffors of Cyrus. She bellowed on her three fons a Latin education, and often Ihewed them to the troops adorned with the imperial purple. For herfelf Ihe referved the diadem, with the fplendid but doubtful title of Queen of the Eaf. When Aurelian palled over into Afia, againft an adverfary whofe fex alone could render her an objedl of contempt, his prefence reftored obedience to the province of Bithynia, already fiiaken by the arms and intrigues of Zenobia. Advancing at the head of his legions, he accepted the fubmiffion of Ancyra; and was admitted into Tyana, after an qbftinate liege, by the help of a perfidious citizen. The generous, tho’ fierce temper of Aurelian, abandoned the traitor to the rage of the foldiers: a fuperftitious reverence induced him to treat with lenity the countrymen of Apollonius the philofopher. Antioch was deferted on his approach; till the emperor, by his falutary edidts, recalled the fu¬ gitives, and granted a general pardon to all who, from recefiity rather than choice, had been engaged in the fervice of the Pahnyrenian queen. The unexpedled mildnefs of fuch a condud reconciled the minds of the Syrians, and, as far as the gates of Emefa, the wilhes Palmyra. of the people feconded the the terror.of his arms. ' Zenobia would have ill deferved her reputation, had file indolently permitted the emperor of the Weft to approach within 100 miles of her capital. The fate of the Eaft was decided in two great battles; fo fimi- lar in almoft every circumftance, that we can fcarcely diftinguilh them from each other, except by obferving that the firft was fought near Antioch, and the fecond near Emefa. In both, the queen of Palmyra anima¬ ted the armies by her prefence, and devolved the exe¬ cution of her orders on ZaLdas, who had already fig- nalized his military talents by the conqueft of Egypt. The numerous forces of Zenobia,.confifted for the moft part of light archers, and of heavy cavalry clothed in complete fteel. The Moorifh and Illyrian horfe of Aurelian were unable to fuftain the ponderous charge of their antagonifts. They fled in real or affefted dif- order, engaged the Palmyrenians in a laborious pur- fuit, harafled them by a defultory combat, and at length difeomfited this impenetrable but unweildy body of cavalry. The light infantry, in the mean time, when they had exhaufted their quivers, remain¬ ing without proteflion againft a clofer onfet, expofed their naked fides to the fwords of the legions. Aure¬ lian had chofen thefe veteran troops, who were ufua-lly ftationed on the Upper Danube, and whofe valour had been feverely tried in the Allemannic war. After the defeat of Emefa, Zenobia Bound it impofiible to col left a third army. As far as the frontier of Egypt, the nations fubjedl to her empire had joined the ftandard of the conqueror; who detached Probus, the bra veil of his generals, to poffefs himfelf of the Egyptian pro¬ vinces. Palmyra was the laft refourcc of the widow of Odenathus. She retired within the walls of her capi¬ tal ; made every preparation for a vigorous refiftance ; and declared with the intrepidity of a heroine, that the laft moment of her reign and of her life fhould be the fame. In his march over the Tandy defart, between Emefa and Palmyra, the emperor Aurelian was perpetually, harafled by the Arabs; nor could he always defend his army, and efpecially his baggage, from thofe flying troops of aftive and daring robbers, who watched the moment of furprife, and diredled the flow purfuit of the legions. The liege of Palmyra was an objed far more difficult and important; and the emperor, who with in- ceflant vigour preffed the attacks in perfon, was him¬ felf wounded with a dart. “ The Roman people, (fays Aurelian, in an original letter), fpeak with con¬ tempt of the war which I am waging againft a woman. They are ignorant both of the chara&er and of the power of Zenobia. It is impoffible to enumerate her warlike preparations, of ftones, of arrows, and of every fpecies of miffile weapons. Every part of the walls is provided with two or three baliflae, and artificial fires are thrown from her military engines. The fear of punifliment has armed her with a defperate courage. Yet I trull Hill in the proteding deities of Rome, who have hitherto been favourable to all my undertakings.”" Doubtful, however, of the protedion of the gods, and of the event of the fiege, Aurelian judged it more pru¬ dent to offer terms of an advantageous capitulation : to the queen, a fplendid retreat; to the citizens, their ancient privileges. His propofals were obftinately re-. P A L [ 5841 1 PAN Palmyrn. jefted, and the refufal was accompanied with Infult. , The fiimnefs of Zenobia was fupported by the hope, that in a very fhort time famine would compel the Ro¬ man army to repafa the defart; and by the reafonable expectation that the kings of the Eaft, and particular¬ ly the Perfian monarch, would arm in the defence of. their mo'fl; natural ally. But fortune, and the perfe- verance of Aurelian, overcame every obltacle. The death of Sapor, which happened about this time, di- ftra&ed the councils of Perfia; and the inconfiderahle fuccours that attempted to relieve Palmyra, were eafily intercepted either by the arms or the liberality of the emperor. From every part of Syria a regular fuccef- lion of convoys fafely arrived in the camp, which was increafed by the return of Probus with his vi&orious troops from the conqoeft of Egypt. It was then that Zenobia refolved to fly. She mounted the fleeted of her dromedaries; and had already reached the banks of the Euphrates, about 60 miles from Palmyra, when fhe was overtaken by the purfnit of Aurelian’s light- horfe, feized, and brought back a captive to the feet of the emperor. Her capital foon after furrendered, and was treated with unexpe&ed lenity. The arms, horfes, and camels, with an immenfe treafure of gold, filver, filk, and precious flones, were all delivered to the conqueror; who, leaving only a garrifon of 600 archers, returned to Emefa, and.employed fome time in the didribution of rewards and punifhments at the end of fo memorable a war, which redored to the obe¬ dience of Rome thofe provinces that had renounced their allegiance fince the captivity of Valerian. When the Syrian queen was brought into the pre¬ fence of Aurelian, he dernly afked her, How fhe had prefumed to rife in arms againd the emperors of Rome? The anfwer of Zenobia was a prudent mixture of re- fpe& and firmnefs: “ Becaufe I difdained to confider as Roman emperots, an Aureolus or a Galienus. You alone I acknowledge as my conqueror and my fove- reign.” But as female fortitude is commonly artifi¬ cial, fo it is feldom deady or confident. The courage of Zenobia deferted her in the hour of trial; fhe trem¬ bled at the angry clamours of the foldiers, who called aloud for her immediate execution ; forgot the gene¬ rous defpair of Cleopatra, which fhe had proposed as her model; and ignominioufly purchafed life by the fa- crifice of her fame and her friends. It was to their counfels which governed the weaknefs of her fex, that fhe imputed the guilt of her obdinate refidance; it was on their heads that fne direfted the vengeance of the cruel Aurelian. The fame of Longinus, who was in¬ cluded among the numerous and perhaps innocent vic¬ tims of her fear, will furvive that of the queen who be¬ trayed, or the tyrant who condemned him. Genius and learning were incapable of moving a fierce unlettered foldier, but they had ferved to elevate and harmonife the foul of Longinus. Without uttering a complaint, he calmly followed the executioner, pitying his un¬ happy midrefs, and bedowing comfort on his afflicted friends. Returning from the conqued of the Ead, Aurelian had already crofied the dreights which divide Europe from Afia; when he was provoked by the intelligence that the Palmyrenians had maffacred the governor and garrifon which he had left among them, and again erefied the ftandard of revolt. Without a moment’s Palpable deliberation, he once more turned his face towards TJ! Syria. Antioch was alarmed by his rapid approach, an' and the helplefs city of Palmyra felt the irrefidible weight of his refentment. We have a letter of Aure¬ lian himfelf, in which he acknowleges, that old men, women, children, and peafants, had been involved in that dreadful execution, which fhould have been con¬ fined to armed rebellion : and although his principal concern feems directed to the re-eftabliihment of a temple of the Sun, he difcovers fome pity for the rem¬ nant of the Palmyrenians, to whom he grants the permiffion of rebuilding and inhabiting their city. But it is eafier to deftroy than to reftorc. The feat of commerce, of arts, and of Zenobia, gradually funk into an obfcure town, a trifling fortrefs, and at length a miferable village. Th« ruins of its temples, palaces, and porticos of Grecian archite&ure, lie fcattered over an extent of feveral miles. Thefe magnificent remains were accidentally difcovered by fome Englifti travellers from Aleppo about a century ago; and moft fplendid views have fince been given of them by MefTrs Wood and Dawkins, to whofe work the curious reader is re¬ ferred.

He afterwards diftin- guifhed himfelf in the war with the giants, when he en¬ tangled Typhon in his nets.

He had a contett with ” ' Cupid ; but was conquered by the little god, whopu- nilhed him, by infpiring him with a paffion for the nymph Syrinx, who treated him with difdain : but he clofely purfuing her, overtook her by the river Ladon, when, invoking the Naiads, flie was changed into a tuft of reeds, which the difappointed lover grafped in his arms; but obferving, that as they trembled with the wind, they formed a murmuring found, he made of them the pipe for which he became fo famous. He charmed Luna in the (hape of a beautiful ram, and had feveral other amours. Pan is reprefented with a fmiling ruddy face, a thick beard, with the horns, legs, feet, and tail of a goat; holding a (hepherd’s crook In one hand, and his pipe of unequal reeds in the other. The abbe Banier remarks, that if ever the Greeks corrupted ancient hiftory, it was in fabricating the fable of Pan. According to them, fays Herodotus, Hercules Dionyfius, or Bacchus, and Pan, were the lad of all the gods : however, in the opinion of the Egyptians, Pan was one of the eight great divinities that formed the firft clafs in their theology, which were the moft powerful and the moft ancient of all. Diodorus makes him one of the attendants upon Ofiris, in his Indian expedition. “ Ofiris,” fays this author, took with him Pan, aperfon much refpe&ed throughout his dominions: for he had not only his fta- tue afterwards placed in all the temples, but a city was built in the Thebaid ; which, in honour of Pan, was called Chemmisy or Chammo, a word that lignifies in the Egyptian language the city of Pan.” The fame author, however, teljs us, that he was the leader of a troop of fauns and fatyrs, or wild and ruftic men, much addifted to finging, dancing, and feats of a&ivity, who were prefemed to Ofiris in Ethiopia, and with whom that prince was fo much pleafed, that he retained them in his fervice. Pan was regarded by the Egyptians, after his apo- theofis, as the god who prefided over the whole uni- verfe, as cmne, implies. He reprefented nature and feftivity ; and was god of the woods and fields, ■wholly taken up with the pleafures of a country life ; dancing conftantly with the fauns and fatyrs ; and runf ning after the nymphs, to whom he was fuch a terror, that it is fuppofed the word panic is derived from Pa~ fiici terrores, with which thofe who were faid to have feen him were feized. Apuleius, however, gives an agreeable defcription of him. “ By chance the god Pan happened to be feated on a little eminence near a river; and, always conftant in his love to the nymph Syrinx, transformed into a reed, he taught her to produce all kinds of agreeable founds, while his goats were {kipping round him, and feeding on the banks.” Luciau defcribes him as the companion, minifter, and counfellor of Bacchus. He was a kind of Scrub, a drudge fit for all work, having been occafionally employed in the capacity of fliepherd, mufician, dan¬ cer, huntfraan, and foldier. In fhort,. he ferved not only as maejlro di capello, in dire&ing the Bacchanals, but was fo expert in playing upon flutes, and was fuch an excellent piper cn the fiftula, that Bacchus was ne¬ ver happy without him. He was particularly honoured in Arcadia, where the ihepherd$ cfcred him milk sad hooey in wooden bowls: when fuccefsful in hunting, they gave him a Panacea part of the fpoils ; but if they caught nothing, they II {hewed their refentment by whipping his image. j Panama. The Romans adopted him amongft their deities un- " der the names of Lupercus and Lycceus. PANACEA, among phyficians, denotes an uni- verfal medicine, or a remedy for all difeafes ; a thing impoffible to be obtained. PANADA, a diet confifting of bread boiled in water to the confiftence of pulp, and fweetened with a little fugar. PANAMA, the capital city of the province of Da¬ rien in South America, where the treafures of gold and filver, and the other rich merchandifes of Peru, are lodged in magazines till they are fent to Europe. W. Long. 82.0. N. Lat. 9. o. This town, which had been the gate through which an entrance was gained into Peru, had rifen to great profperity, when, in 1670, it was pillaged and burnt by pirates. It was rebuilt on a more advantageous fpot, at the diftance of four or five miles from the firfi. Its harbour, called Peri(o, is very fecure. It is form¬ ed by an archipelago, confifting of 48 fmall iflands, and is capable of containing the largelt fleets. This place, a little while after it was founded, be¬ came the capital of the kingdom of Terra Firma. Some hope? were at firft entertained from the three provinces of Panama, Darien, and Veragua, which compofed it; but this prpfperity vaniflied inftanta- neoufly. The favages of Darien recovered their inder pendence $ and the mines of'the two other provinces were found to be neither fufficiently abundant, nor of an alloy good enough to make it worth while to work them. Five or fix fmall boroughs, in which are feen fome Europeans quite naked, and a very fmall num¬ ber of Indians, who have come to refide there, form the whole of this ftate, which the Spaniards are not afliamed of honouring with the great name of king¬ dom. It is in general barren and unwholefome, and contributes nothing to trade but pearls. The pearl fiftiery is carried on in the iflands of the gulph. The greateft part of the inhabitants employ fuch of their negroes in it as are good fwimmers. Thefe flaves plunge and replunge in the fea in fearch of pearls, till this exercife has exhaufted their ftrength or their fpirits. Every negro is obliged to deliver a certain number of oyfters. Thofe in which there are no pearls, or in which the pearl is not entirely formed, are not reckon¬ ed. What he is able to find beyond the ftipulated obligation, is confidered as his indifputable property : he may fell it to whom he pleafes ; but commonly he cedes it to his mafter at a moderate price. Sea monfters, which abound more about the iflands where peans are found than on the neighbouringcoafts, render this fifhing dangerous. Some of thefe devour the divers in an inftant. The manta fifli, which de¬ rives its name from its figure, furrounds them, rolls them under its body, and fuffocates them. In order to defend themfelves againft fuch enemies, every diver is armed with a poinard: the moment he perceives any of thefe voracious fifli, he attacks them with precau¬ tion, wounds them, and drives them away. Notwith- ftanding this, there are always fome filhermen deftroy- ed, and a great number crippled. The PAN [ 5843 ] PAN Pan»n The pefirla of Panama are commonly of a very fine H water- Some of them are even remarkable for their Jj^fl_fizeand figure: thefe were formerly fold in Europe. Since art has imitated them, and the paflion for diamonds has entirely fuperfeded or prodigioufly di- miniflied the ufe of them, they have found a new mart more advantageous than the firft. They are carried to Peru, where they are in great eftimation. This branch of trade has, however, infinitely lefs contributed to give reputation to Panama, than the advantage which it hath long enjoyed of being the mart of all the produ&ions of the country of the Incas, that are deftined for the old world. Thefe riches, which are brought hither by 3 fmall fleet, were carried, fome on mules, others by the river Chagre, to Porto Bello, that is fituated on the northern coaft. of the ifthmus which feparates the two feas.

PANATHEN./EA, in Grecian antiquity an an¬ cient Athenian feftival, in honour of Minerva the proteftrefs of Athens, and called Athcnxa. There were two fettivals under this denomination, the greater and the It Her. The greater panathenaea were exhi¬ bited every five years ; the lefs every three, or, ac¬ cording to fome writers, annually. Though the cele¬ bration of neither, at firft, employed more than one day ; yet in after-times they were protrafted for the fpace of many days, and folemnized with greater pre¬ parations and magnificence than at their firft inftitu- tion. Prizes were eftablifhed there for three different kinds of combat : the firft confifted of foot and horfe races ; the fecond, of athletic excercifes ; and the third, of poetical and mufical contefts. Thefe laft are faid to have been inftituted by Pericles. Singers of the firft clafs, accompanied by performers on the flute and cithara, exercifed their talents here, upon fubje& per- fcribed by the diredlors of thefc exhibitions. And while the Athenian ftate was free and independent, the noble and generous actions of Harmodius and Ariftogiton, who had oppofed the power of the Pifi- ftratidas, and of Ariftobulus, who had delivered the Athenians from the oppreflion of the thirty tyrants impofed upon them by the Lacedsemonians, were cele¬ brated in thefe fongs. PANAX, Ginseng, a genus of the dioecia or¬ der, belonging to the polygamia clafs of plants. There are two fpecies, the quinquefolium and trifolium. Both thefe are natives of North America. The former is generally believed to be the fame with the Tartarian ginfeng ; the figures and defcriptions of that plant which have been fent to Europe by the mif- fionaries, agreeing perfe&ly with the American Plant. This hath a jointed, fleftiy, and taper root, as large as a man’s finger, frequently divided into two fmaller fibres downwards. The ftalks rifes near a foot and ■an half high, and is naked at the top, where it gene¬ rally divides into three fmaller foot-ftalks, each fu- Panart, ftaining a leaf compofed of five fpear-ftiaped lobes, panuV- fawed on their edges: they are of a pale green, and a little hairy. The flowers grow on a flender foot- ftalk, juft at the divifion of the foot-ftalks which fuftain the leaves, and are formed into a fmall umbel at the top; they are of an herbaceous yellow colour, compofed of fmall yellow petals, which are recurved. Thefe appear the beginning of June; and are fucceeded by compreffed, heart-lhaped berries, which are firft green, but afterwards turn red; inclofing two hard, compreffed, heart-fhaped feeds, which ripen in the beginning of Auguft. The fecond fort grows naturally in the fame countries: but Mr Miller never faw more than one plant, which was fent to him from Maryland, and did not live beyond the firft year ; being planted in a dry foil, in a very dry feafon. The llalk was Angle, and did not rife more than five inches in height, dividing into three foot-ftalks, each fuftaining a trifoliate leaf, whofe lobes were longer, narrower, and deeper indented on their edges, than the former. The flower-ftalk rofe from the divifions of the foot- ftalk of the leaves ; but before the flowers opened, the plant decayed. Properties. The root of this plant is ufed in me¬ dicine. It is two or three inches long, taper, about the thicknefs of the little finger, often forked at the bottom, which gives it a diftant refemblance of a man, whence it is called ginfeng; it is elegantly ftriated with circular wrinkles; it is of a browniih yellow colour on the outfide, and whitifli or of a pale yellow within ; on the top are commonly one or more little knots, which are the remains of the ftalks of the preceding years, and from the number of which the age of the root is judged of. Thofe roots which are brought from China are foroewhat paler than thofe from America, but in no atherrefpedt is any difference found. The Chinefe efteera the ginfeng root as a general reftorative and corroborant: to the tafte it is mucila¬ ginous, and fweet like liquorice; yet accompanied with a degree of bitternel's and a flight aromatic warmth, with little or no fmell: the fweet matter of thefe roots is preferved in the watery as well as in the fpirituous extraft, and fo is their aroma; the fpiri- tuous extradf is a pleafant warm bitterifh fweet. A dram of the ginfeng root may be fliced and boiled in a quarter of a pint of water to about two ounces ; then a little fugar being added, it may be drank as foon as it is cool enough: the dofe muft be repeated morning and evening ; but the fecond dofe may be prepared from the fame portion of root which was ufed at firft, for it may always be twice boiled. The plant has been introduced into the Britifh gardens, and will thrive in thofe places where it hath a light foil and fhady fituation, and will produce flowers and feeds ; but the latter, though in appearance ripe and perfeft, will not produce any new plants, as Mr Miller fays he has repeatedly made the experiment, and waited for them three years without difturbing the ground. PANAY, an ifland of AGa, and one of the Phi¬ lippines, lying between thofe of Paragoa and Negro. It is 250 miles in circumference, and is the moft po¬ pulous and fertile of them all.

PAN'THEON, a beautiful edifice, at Rome, anci¬ ently a temple, dedicated to all the gods; but now Pantheon, .converted into a church, and dedicated to the Virgin-*" ; " and all the martyrs. This edifice is generally thought to have been built by Agrippa fon-in-law to Auguftus, becaufe it has the following infcription on the frieze of the portico : M. AGRIPPA L. F. COS. TERTIUM FECIT. Several antiquarians and artifts, however, have fup- pofed that the pantheon exifted in the times of the commonwealth; and that it was only embellifhed by Agrippa, who added the portico. Be this as it will, however, the pantheon when perfe&ed by Agrippa was an exceedingly magnificent building; the form of whole body is round or cylindrical, and its roof or dome is fpherica): it is 144 feet diameter within; and the height of it, from the pavement to the grand aper¬ ture on its top, through which it receives the light, is juft as much. It is of the Corinthian order. The inner circumference is divided into feven grand niches, wrought in the thicknefs of the wall: fix of which are flat at the top; but the feventh, oppofite to the entrance, is arched. Before each niche are two columns of an¬ tique yellow marble fluted, and of one entire block, making in all 14, the fineft in Rome. The whole wall of the temple, as high as the grand cornice inclufive, is cafed with divers forts of precious marble in compart¬ ments. The frieze is entirely of porphyry. Above the grand cornice arifes an attic, in which were wrought, at equal dift.ances, 14 oblong fquare niches: between each niche were four marble pilafters, and between the pila- lafters marble tables of various kinds. This attic had a complete entablature; but thecoroice proje&ed lefs than that of thegrandorderbelow. Immediately from the cor¬ nice fprings the fpherical roof, divided by bands, which crofs each other like the meridians and parallels of an ar¬ tificial terreftrial globe. The fpaces between the bands decreafe in fize as they approach the top of the roof; to which, however, they do not reach, there being a confiderable plain fpace between them and the great opening. That fo bold a roof might be as light as pof- fible, the architeft formed the fubftance of the fpaces between the bands, of nothing but lime and pumice (tones. The walls below were decorated with lead and brafs, and works of carved filver over them ; and the roof was covered on the outfide with plates of gilded bronze. There was an afeent from the fpringtng of the roof to the very fummit by a flight of feven flairs. And if certain authors may be credited, thefe flairs were ornamented with pedeftrian ftatues, ranged as an amphitheatre. This notion was founded on a pafiage of Pliny, who fays, “ That Diogenes the fculptor de¬ corated the pantheon of Agrippa with elegant ftatues;,- yet that it was difficult to judge of their merit, upon account of their elevated fit nation.” The portico is compofed of 16 columns of granite, four feet in dia¬ meter, eight of which (land in frontj with an equal tn- tcrcolumniation all along, contrary to the rule of Vi¬ truvius,, who is for having the fpace anfwering to the door of a temple, wider than the reft. On thefe co¬ lumns is a pediment, wbofe tympanum, or flat, was or¬ namented with bas-reliefs in brafs ; the crofs beams which formed the ceiling of the portico were covered with the fame metal, and fo were the doors. The afeent up to the portico was by eight or nine fteps. Such was the pantheon; the richnefs of vvhich^ndu- cedl PAN [ 5846 ] PAN Pantheon, ced Pliny to rank it among the wonders of the world* _ eruption of Vefuvius, in the reign of Tiberius, damaged the pantheon very confiderably; it was re¬ paired by Domitian, which occafioned fome writers to mention that prince as the founder of the building. The emperor Adrian alfo did fomething to it. But it ap¬ pears, that the pantheon is more indebted to Septimius Severus, than to any one fince its ere&ion. The mod, perhaps, that any of his predeceflbrs had done, was the adding fome ornament to it: Septimius beftowed eflen- tial reparations upon it.

It is really a manner of aftonifhment, that a ft rue- ture, which, granting it to have been buflt by Agrip- pa, was not more than 200 years old, (hould have fallen into decay through age. This firtgle eonfideration feems fufficient to confirm the opinion of thofe Who be¬ lieve it to have flood in the time of the comifionwealth. The temple fubfifted in all its grandeur, till the in- enrfion of Alaric in the time of Honorius. Zozytfius relates, that the Romans having engaged to fumifh this barbarian prince with 300G pounds weight of gold, and 5000 pounds weight of filver, upon condition that he fliould depart from their walls; and it proving im- pofiible to raife thofe futns either out of the public treafury or private purfes* they were obliged to (trip the temples of their ftatues and ornaments of gold and filver. It is probable that the pantheon fupplied a good part, as that of Jupiter Capitolinus was the only one in Rome that could vie with it for riches. Alaric carried off nothing from the Romans befides their precious metals. Thirty-nine years after this, Genferic king of the Vandals took away part of their marbles; and whether from a greedinefs of plunder, or from a relifli of the produdfions of art, loaded one of his (hips with ftatues. It cannot be queftioned, but that on this occafion the pantheon was forced to part with more of its ornaments, and that the ineftimable works of Diogenes became the prey of this Barbarian. Before thefe unwelcome vifits of the Goths and Van¬ dals, the Chriftian emperors had iffued- edifts for demo- lifhing the pagan temples. But the Romans, what¬ ever were their motives, fpared the pantheon, which is known to have fufFered no damage from the zeal of the pontiffs, or the indignation of the faints, before the firft liege of Rome by Alaric. It remained fo rich till a- bout the year 655, as to excite the avarice of Conftan- tine II. who came from Conftantinople to pillage the antheon, and executed his purpofe fo far as to ftrip it oth of its infide and outfide brazen coverings, which he- tranfported to Syraeufe, where they foon after fell into the hands of the Saracens. About 50 years before this, pope Boniface IV. had obtained the pantheon of the emperor Phoeas, to make Pantheon, a church of it. The artifts of thofe days were totally — 1 ignorant of the excellence of the Greek and Roman ar- chitefture, and fpoiled every thing they kid their hands upon. To this period, certain alterations are to be re¬ ferred, of which we (hall fpeak by and by. After the devaftations of the barbarians, Rome was contracted within a narrow compafs: the feven hill* were abandoned; and the Campus Martins, being an even plain, and near the Tyber, became the ground- plat of the whole city. The pantheon, happening to Hand at the entrance of the Campus Martius, was pre- fetitly furrounded with houfes, which fpoiled the fine profpeft of it; and it was yet more deplorably difgra- ced by fome of them which flood clofe td its Vvalls. Pedlars fhades were built even within its portico, and the intercolumniations were bricked up, to the irrepa¬ rable damage of the matchle'fs pillars, of Which fome loft part of their capitals, fome of their bafes, and &• thers were ehiffded out fix or (even inches deep, and a* many feet high, to let in polls. Which excavations are to this daiy half filled up with brick and mortar ; a fad monument of the liceniioufnefs of the vulgar, and of the ftupid avariee of thofe Who fold them the privi¬ lege to ruin the ftoblefl piece df art in the world! This diforder edfitirfued till the pontificate of Eu¬ gene IV. whofe zeal for the decency of a confecrated place, prevailed upon him to have all the houfes clear¬ ed away that incumbered the pantheon, and fo the mi- ferable bcirtacks in tile portico were knocked dovt’n. From the time Ccirtftantius eartied off the brafs pla¬ ting df the' externaf fdof,- that fiart was expofed to the injuries df the weather, or sit beft was but flightty tiled in, till Benedict ll. coveted it with lead, which Nicholas V. renewed in a better flyle. It does not appear that frOrn thistfmetoUrbiinVIir. any pope did any thihg remifkalbid to the pantheon. Raphael Urban, who had no equal as a painter, and who as an- architect had ho fuperior, left a cohfiderabJe fum by his will for the f-epbratidri of the pahfheon, where his tomb is placed. Pcrino de la Vagua, Jateo- 1M0 Udino, Anhibkfo Ca-rtachi, Flamingo Vacca, and the celebrated Archangel© Corelli, did the fame. All the ornaments within, that have any claim fo be called good, are of the latter times ; the paintings merit efteem; and the ftatues, though not rriafter-pieces, do honour to fculpture, which alone is a proof that they are pofterfor to the fyth century. But, with all the refpCft due to a pontiff, who was btherwife a proteftor, arid even a praClifer of the arts, it were much td be wifhed that urban VIII. had tic t known that the parttheb-rt exift'ed. The rnferiptidns cut at the fide of the door inform us, that hd repaired it; yet, at the fame time that he built up with one hand, he pulled down with the other. He cauftd two bell- fries of a wretched tafte to be ereCted on the ancient front work, and he divefted the portico of all the re¬ mains of its ancient grandeur, viz. the brazen Cover¬ ture of the crofs beams, which amounted to filch a prodigious quantity, that riot only the vaft baldaqnirt, or canopy, of the confeflional in St Peter’s, was call out of it, but Jikewife a great number of cannon for the caftle of St Angelo. This pope, who was of tile fa¬ mily of Barbarini, preferred alfo as much of this me¬ tal to his nephew, as was fufficient for the decoration PAN Pantheon of his new palace; on which occafion this remarkable H . pafquinade was ftuck up, •Pantomime %>uod non fecerunt Barhari facre Barbarini. IF ever gingle added farce to wit, it was certainly in this inftance. It is furprifing, that whilft all thefe operations were carrying on in the portico, he never once thought of repairing the damages which time had wrought in it! Of the 16 pillars which fupported this magniticent pile, there were no more than 13 left; the three next the temple of Minerva had difappeared; with thefe the~en- tablature and an angle of the front had tumbled down. There were not wanting in Rome fragments enough of antique columns that might have been put together and fet up, to have prevented the downfall of a pile which deferved to (land as long as the world endured. Alexander VII. did what Urban VIII. had neglec¬ ted 'to do. At the fame time that Bernini was con- 11 ru&ing the colonnade of St Peter, this pontiff order¬ ed fearch to be made for pillars to match thofe of the portico of the pantheon; and fome were found not far from the French church of St Lewis, of the very fame model. They were granite of the ifle of Ilva, and thofe of the portico were Egyptian granite; the colour, however, was the fame, fo that the effeft was equal. The pope’s zeal did not flop here ; he caufed all the old houfes before the portico to be pulled down, and the foil and rubbifh to be cleared away, which covered the fleps, and even the bafes of fome of the pillars. He began covering the roof with marble, and r?Jfed a lantern over the aperture, to keep out rain; but death took him off before his projeft was completed. Cle¬ ment IX. his fucceffor, inclofed the portico within iron rails. Several later popes have added to its decora¬ tions, which were all in the tafte of the times they were done in, and the body of the edifice and its architec¬ ture gained nothing from them. The main objeft of their holineffes liberality was the embellifhment of the grand altar. One gave purple curtains, another be¬ llowed filver tabernacles; others again vafes, and fuperb drefles, fuited to the folemn ceremonies of religion. All thefe might be called rich; but they had in no fenfe a tendency to retrieve the ancient majefty or original fplendour of the temple. The true gufto of the orna¬ ments was a little imitated at the revival of the arts. Good ftatues took place of the fkeletons and fquat fi¬ gures that ridiculoufly difgraced the altars for the fpace of eight centuries. The paintings of Perugino, Coz- za, and Greffi, covered the dull mofaics with which the Greeks of Conftantinople had loaded the walls of moft of the churches in Rome. The porphyry and the green and yellow antique, found among the old ruins, were employed to much advantage. PANTHER, in zoology. See Leo. PANTOMIME, naviopipof, among the ancients, a perfon who could imitate all kind of aftions and charafters by figns and geftures, without fpeaking.

PAPAVER, the Poppy; a genus of the monogy- nia order, belonging to the polyandria clafs of plants. Species. 1. The fomniferum, or fomniferous com¬ mon garden-poppy, rifes with an upright fmooth ftalk, dividing or branching a yard or more high; garniftied with large, deeply jagged, amplexicaule, fmooth leaves; and terminated by large, fpreading, dark-purple, and other coloured flowers, in the varieties, having fmooth cups and capfules, flowering in June and July. There are a great many varieties, fome of them extremely beautiful. The white officinal poppy is one of the varieties of this fort. It grows often to the height of five or fix feet, having large flowers both Angles and doubles, fucceeded by capfules or heads as large as oranges, each containing about 8000 feeds. 2. The rhoeas, or wild globular-headed poppy, rifes with an upright, hairy, multiflorous ftalk branching a foot and an half high ; garniftied with long, pinnatified, deeply cut, hairy leaves; the ftalk terminated by many red and other coloured flowers in the varieties, fuc¬ ceeded by globular fmooth capfules. The flowers appear in June. 3. The Cambricum, or Welfti poppy, has a perennial root, pinnated cut leaves, fmooth, up¬ right, multiflorous ftalks a foot and an half high; garniftied with fmall pinnated leaves, and terminated by many large yellow flowers, fucceeded by fmooth capfules. The flowers appear in June. 4. The ori- entalis, or oriental poppy, hath a large, thick, perennial root; long, pinnated, fawed leaves; upright, rough, uniflorous ftalks, terminated by one deep red flower, fucceeded by oval, fmooth, capfules. The flowers appearing in May. Propagation. All the kinds are hardy, and will profper any where. The two firft fpecies being an¬ nual, are to be propagated only by feeds; but the two laft by parting the roots as well as the feeds. Ufes. The fomniferous quality of the white poppy is well known. This quality refides in the milky ■" juice of the capfule containing the feeds, nor is it eva¬ porated by drying the juice ; hence the dried capfules are preferved in the ftiops for making the fyrup. The infpiflated juice itfelf is a kind of opium; and for au account of its virtues fee the article Opium. The feeds alfo make a very agreeable emullion, but have no foporific virtue. PAP AW, or Papa-tree. See Carica.—This tree 33 A ia I 5847 1 PAP [ 5848 ] P* A P P*Pe>'* is male and female upon different roots: the flowers “of the former are white, and of the latter yellowifh. The tender buds of thefe laft are preferved into fweet- meats ; and the long mango-popo, which is faid to be little inferior to an Eaft India mango, into pickles. When nearly ripe, the fruits are likewife boiled and eaten with any kind of flefh-meat, care being taken previoufly to cleanfe them of the milky corrofive juice contained in them, which is of fo penetrating a nature, fays Hughes, that .if the unripe fruit, when unpeeled, is boiled with the tougheft old fait meat, it will foon make it foft and tender; and, if hogs are for any confiderable time fed with the raw fruit, it wears off all the mucous flimy matter which covers the infide of the guts; and would in time, if not prevented by a change of food, entirely lacerate them. This juice, according to Linnaeus, is fometimes made ufe of to cure ring-worms and fuch cutaneous eruptions. It muft be expelled by the medium of falt-water before the fruit is fit for ufe. It is remarkable, that the (talk of this plant is herbaceous and hollow; which laft at¬ tribute has paffed into a proverb in Barbadoes and other Weft India iflands, where it is common to charafterife 3 diffembler, by faying, that he is as hol¬ low as a popo. PAPER, flieets of a thin matter, made of fome vegetable fubftance. The materials on which mankind have, in different ages, contrived to write their-fentiments, have been extremely various; in the early ages they made ufe of ftones, and tables of wood, wax, ivory, &c. See Book. Paper, with regard to the manner of making it, and the materials employed therein, is reducible to feveral kinds; as Egyptian paper, made of the rufh papyrus; bark-paper, made of the inner rind of feve¬ ral trees ; cotton-paper ; incombuftible paper ; and European paper, made of linen rags. Egyptian paper was principally ufed among the ancients ; being made of the papyrus, or biblus, a fpecies of ruih which grew on the bank of the Nile. In making it into paper, they began with lopping off the two extremes of the plant, the head and the root; the remaining part, which was the ftem, they cut lengthwife into two nearly equal parts, and from each of thefe they ftripped the fcaly pellicles of which it confifted. The innermoft of thefe pellicles were looked on as the beft, and that neareft the rind as the worft : they were therefore kept apart, and made to con- ftitute two different forts of paper. As the pellicles were taken off, they extended them on a table, laying them over each other tranfverfely, fo as that the fibres made right angles: in this ftate they were glued together by the muddy waters of the Nile; or, when thofe were not to be had, with pafte made of the •fineft wheat-flour, mixed with hot water and a fprink- ling of vinegar. The pellicles were next preffed to get out the water, then dried, and laftly flatted and fmoothed by beating them with a mallet: this was the Egyptian paper, which was fometimes farther polilhed by rubbing it with a, glafs-ball, or the like. Bark-paper was only the inner whitilh rind, in- clofed between the bark and the wood of feveral trees, as the maple, plane, beech, and elm ; but efpecially the tilia, or linden-tree, wiiisb, was that moftly ufed for this purpofe. On this ftripped off, flatted, and dried, the ancients wrote books, feveral of which are faid to~ be ftill extant. Chinefe paper is ofvan'ous kinds. Some is made of the rinds or barks of trees, efpecially the mulberry-tree and elm, but chiefly of the bamboo and cotton-tree. In faft, almoft each province has its feveral paper. The preparations of paper made of the barks of trees, may be inftaficed in that of the bamboo, which is a tree of the cane or reed kind. The fecond fkin of the bark, which is foft and white, is ordinarily made ufe of for paper; this is beat in fair water to1 a pulp, which they take up in large moulds, fo that fome (beets are above twelve feet in length ; they are completed, by dipping them (beet by (heet in alum-water ; which ferves inftead of the fize among us, and not only hinders the paper from imbibing the ink, hut makes it look as if varniflied over. This paper is white, foft, and clofe, without the lead roughnefs; though it cracks more eafily than European paper, is very fubje& to be eaten by the worms, and its thinnefs makes it liable to be foon worn out. Cotton-paper is a fort of paper which has been in ufe upwards of 600 years. In the French king’s libra¬ ry are manuferipts on this paper, which appear to be of the 10th century; and from the 12th century, cotton manuferipts are more frequent than parchment ones. Cotton-paper is ftill made in the Eaft Indies, by beating cotton-rags to a pulp. Linen or European paper appears to have been firft introduced among us towards the beginning of the 14th century ; but by whom this valuable commodity was invented, is not known. The method of making paper of linen or hempen rags, is as follows: The linen-rags being carried to the mill, are firft forted, then waflied very clean in puncheons, whofe fides are grated with ftrong wires, and the bottoms bored full of holes. After this they are fermented, by laying them in heaps clofe covered with facking, till they fweat and rot, which is colnmonly done in four or five days. When duly fermented, they are twifted into handfuls, cut fmail, and thrown into oval mortars, made of well- feafoned oak, about half a yard deep, with an iron- plate at bottom, an inch thick, eight inches broad, and thirty long ; in the middle is a waffiing-block, grooved, with five holes in it, and a piece of hair- fieve faftened on the infide; this keeps the hammers from touching it, and. prevents anything going out except foul water. Thefe mortars are continually fup- plied with water, by little troughs from a ciffern, fed by buckets fixed to the feveral floats of a great wheel, which raifes the wooden hammers for pounding the rags in the mortars. When the rags are beaten to a certain degree, called the jf/fl fluff, the pulp is re¬ moved into boxes, made like corn-chandlers bins, with the bottom-board aflant, and a little feparation on the front for the water to drain away. The pulp of the rags being in, they take away as many of the front- boards as are needful, and prefs the mafs hard down with their hands; the next day they put on another board, and add more pulp, till the box is full; and here it remains mellowing a week, more or lefs, ac¬ cording to the weather. After this, the fluff is again put into clean mortars, and is beaten afrefti, and re¬ moved into boxes, as before; in which hate it is called Paper. PAP [ 5849 ] PAP ‘Paper, the fecond Jluff. The mafs is beat a third time, till feme of it being mixed with fair water, and brewed to and fro, appears like flour and water, without any lumps In it: it is then fit for the pit-mortar, where it is perfectly diflblved, and is then carried to the vat* to be formed into fheetsof paper. But lately, iuftead of pounding the rags to a pulp with large hammers, as above, they make ufe of an engine, which per¬ forms the work in much lefs time. This engine con- fifts of a round folid piece of wood, into which are fattened feveral long pieces of fteel, ground very fliarp. This is placed in a large trough with the rags, and a fufficient quantity of water. At the bottom of the trough is a plate with fteel bars, ground (harp like the former ; and the engine being carried round with pro¬ digious velocity, reduces the rags to a pulp in a very fhort time. It muft be obferved, that the motion of the engine caufcs the water in the trough to circulate, and by that means conftantly returns the ftuff to the engine. The trough is conftantly fed with clean water at one end, while the dirty water from the rags is carried off at the other, through a hole, defended with wire gratings, in order to hinder the pulp from going out^with the dirty water. When the ftuff is fufficiently prepared as above, it is carried to the vat, a»d mixed with a proper quantity of water, which they call priming the vat. The vat is rightly primed, when the liquor has fuch a proportion of the pulp, as that the mould, on being dipped into it, will juft take up enough to make a (beet of paper of the thicknefs required. The mould is a kind of fieve exaftly of the fize of the paper to be made, and about an inch deep, the bottom being formed of fine brafs wire, guarded underneath with (ticks, to prevent it bag¬ ging down, and to keep it horizontal; and further, to ftrengthen the bottom, there are large wires placed in parallel lines, at equal diftances, which form thofe lines vifible in all white paper when held up to the light: the mark of the paper is alfo made in this bottom, by interweaving a large wire in any particular form. This mould the maker dips into the liquor, and gives it a fhake as he takes it out, to clear the water from the pulp. He then Aides it along a groove to the coucher, who turns out the (heet upon a felt laid on a plank, and lays another felt on it; and returns the mould to the maker, who by this time has prepared a fecond fheet in another mould: and thus they proceed, laying alter¬ nately a (heet and a felt, till they have made fix quires of paper, which is called a poji; and this they do with fuch fwiftnefs, that, in many forts of paper, two men make 20 pofts and more in a day. A poft of pa¬ per being made, either the maker or coucher whiftles; on which four or five men advance, one of whom draws it under the prefs, and the reft prefs it with great force, till all the water is fqueezed from it ; af¬ ter which it is feparated (heet by (heet from the felts, and laid regularly one (heet upon another ; and having undergone a fecond prefling, it is hung up to dry. When fufliciently dried, it is taken oft' the lines, rub- "bed fmooth with the hands, and laid by till fized; which is the next operation. For this they choofe a fine temperate day ; and having boiled a proper quan¬ tity of clean parchment, or vellum-ftravings, in water, till it comes to a fize, they prepare a fine cloth, on which they drew a due proportion of white vitriol and roch alum finely powdered, and drain the fize through Papw, it into a large tub; in which they dip as much paper “““ at once as they can conveniently hold, and with a quick motion give every fheet its (hare of the fize, which muft be as hot as the hand can well bear it. After this, the paper is preffed, hung up (heet by fheet to dry ; and being taken down is forted, and what is on¬ ly fit for outfide-quires laid by themfelves: it is then told into quires, which are folded and preffed. The bro¬ ken (lieets are commonly put together, and two of the worft quires are placed on the outfide of every ream or bundle : and being tied up in wrappers, made of the fettling of the vat, it is fit for fale. Paper is of various kinds, and ufed for various purpofes : with regard to colour, it is principally di- ftinguifhed into white, blue, and brown; and with re¬ gard to its dimenfions, into atlas, elephant, imperial, fuper-royal, royal, medium, demy, crown, fools-cape, and pot-paper. Mr Guettard of the Royal Academy of Sciences in France has given an account of a number of experi¬ ments on materials for making paper ; with’ a view, if poflxble, to procure this ufeful fubftance from fuch others as are always to.be had in greater plenty than rags can be got; of which therfc is fometimes a con- fiderablc fcarcity. Mr Reaumur has obferved, that vrafps have a method of preparing bits of rotten wood whereby they build their nefts, in fuch a manner, that it looks like ftrong paper or pafteboard. Seba, in the firft volume of his Natural Hiftory, propofes the alga marina. “ This country (fays he) does not feem to want trees fit for making paper, if people would give themfelves the neceffary trouble and expence. Alga marina, for example, which is compofed of long, ftrong, vifeous filaments, might it not be proper for this purpofe, as well &s the matts of Mufcovy, if they were prepared as the Japanefe make their paper? The curious may at leaft try the experiment.” P. du Halde, in the firft volume of his Hiftory of China, pretends, that the Chinefe make paper of the fecond bark of bamboo, of the bark of different trees, particularly the mulberry, of ftraw, rue, and hemp. Other nu- thors mention its having been made of mallows, and feveral different kinds of herbs. All Mr Guettard’s trials, however, proved unfuceefsful, and flax, cotton, hemp, and filk, feem to Ire the only materials of which - it is poffible to make this valuable commodity. The reafon of thefe failures was, that the abovementioned fubftances only feem capable of being reduced to fibres indefinitely fine, and which at the fame time preferve a confiderable degree of toughnefs ; all others being very coarfe in the fibre itfelf, and foon reducible to their ultimate finenefs ; and what is worfe, the fibres are brittle, fo that the paper when made has no cohefion. Our author, however, has found, that pa¬ per may be made from flax, hemp, and filk, without the trouble of manufa&uring them into cloth; and therefore he recommends the dreffings of the two for¬ mer, which are fometimes in fuch abundance as to be thrown away; but if we confider the great trouble which mull be neceffary to bring thofe materials to a proper colour, and the great diminution of them which muft neceffarily enfue during the tedious opera¬ tion, it is not probable that any advantage could be gained in this way. - - A - P/ r- 33 A 2 Paper. PAP [ 5850 ] PAP Preparation of Pap er for durable writing. For this purpofe Dr Lewis recommends the impregnation of it with aftringent materials. “ It is obfervable (fays he) that writings firft begin to fade or change their colour on the back of the paper, where the larger flrokes have funk in, or are vifible through it ; as if part of the irony matter of the vitriol was in a more fubtile or diflblved (late than the reft, and funk further, on ac¬ count of its not being fully difengaged from the acid, or fufficiently combined with the aftringent matter of the galls. Hence, it fhould feem probable, that if the paper was impregnated with aftringent matter, the co¬ lour of the ink would be more durable. To fee how far this notion was well founded, I dipt-fome paper in an infufion of galls; and, when dry, repeated the dipping' a fecond and third time. On the paper thus prepared, and fome that was unprepared, I wrote with different inks; feveral of which, that the effects might be more fenfible, had an over-proportion of vitriol. The wri¬ tings being expofed to the weather till the beft of the inks on the unprepared paper had faded and changed their colour, thofe on the prepared paper were all found to retain their blacknefs. It is therefore re¬ commended to the confideration of the paper-makers, whether a particular kind of paper might not be pre¬ pared for thofe ufes where the long duration of the writing is of principal importance, by impregnating it with galls or other aftringents, in fome of the opera¬ tions it paffes through before it receives the glazing ; as for inftance, by ufing an aftringent infufion, inftead of common water, in the laft operation, when the matter is reduced into a pulp for being formed into fheets. The brownifh hue which the paper receives from the galling, would not perhaps be any great ob- flacle to its ufe; and, if the propofal fhould be thought worthy of being carried into execution, fur¬ ther inquiries may poffibly difcover the means of ob¬ viating the imperfeftion, and communicating aftringen- cy without colour. Staining or Colouring of Paper. The colours pro¬ per for paper are not different from thofe ufed for other fubftances, and are enumerated under the article Co- xovvi-Making. They are applied with foft brufhes, after being tempered to a due degree with fize or gum water. If the paper on which they are to be laid is foft, fo that the colours are apt to go through, it muft alfo be fized before they are laid on, or a pro- portionably larger quantity muft be ufed along with the colours themfelves. If a confiderable extent of the paper is to be done over with one colour, it muft receive feveral coatings, as thin as poffible, letting each coat dry before another is put on, otherwife the colour will be unequal. Ti? Paper. Take yellow oker, grind it with rain-water, and lay a ground with it upon the paper all over ; when dry, take the white of eggs, beat it clear with white fugar-candy, and ftrike it all over: then lay on the leaf-gold; and, when dry, polilh it with a tooth. Some take faffron, boil it in water, and diffolve a little gum with it; then they ftrike it over the paper, }ay on the gold; and, when dry, they polifti it. To fiver Paper, after the Chinefe mannerl without filver. Take two fcruples of clear glue made of neats leather, one fcruple of white allum, and half a pint of clear water ; fimmer the whole over a flow fire, till the water is confumed, or the fleam ceafes: Then, ~ your fheets of paper being laid on a fmooth table, you dip a pretty large pencil into that glue, and daub it over as even • as you can, repeating this two or three times : then fift the p.owder of talc through a fine fieve, made of horfe-hair or gaufe, over it; and then hang it up to dry; and, when dry, rub off the fuperflu* ous talc, which ferves again for the fame purpofe. The talc you prepare in the following manner: Take fine white tranfparent Mufcovy talc ; boil it in clear water for four hours ; then take it off the fire, and let it Hand fo for two days : then take it out, wafh it well, and put it into a linen-rag, and beat it to pieces with a mallet: to 10 pounds of talc add 3 pounds of white allum, and grind them together in a little hand-mill; fift it through a gauze-fieve ; and being thus reduced to a powder, put it into water, and juft boil it up: then let it fink to the bottom, pour off the water from it, place the powder in the fun to dry, and it will be¬ come a hard confiftence. This beat in a mortar to an impalpable powder, and keep it, for the ufe above- mentioned, free from dull. ¥Kvve.-Hangbigs} furniture now greatly ufed, and generally approved, as it is at once airy and cheap. The paper manufactured for hangings is of feveral kinds, fome being made in reprefentation of ftucco work, for the covering cielings or the fides of halls, ftair-cafes, paffages, &c. and others jn imitation of velvet, damalk, brocades, chints, or other fuch filks and fluffs as are employed for hanging rooms. The principal difference in the manufadture lies, however, in the grounds: fome of which are laid in varnifh, and others in the common vehicles for water-colours; and in the raifing a kind of coloured emboffment by chopt cloth, which is called flock-paper. Unwrought Paper proper for Hangings*—The kind of paper employed for making the paper-hangings is a fort of coarfe cartoon manufactured for this purpofe; and there being a particular duty on paper-hangings, it is required, under confiderable penalties, to be damp¬ ed before it be painted or otherwife decorated for this purpofe. There is no occafion, however, to be more particular in explaining the qualities of this kind of unwrought paper; becaufe it is to be had of all the great dealers in paper, manufadtured in a proper manner White and coloured Grounds for 'Paver-Hangings. The common grounds laid in water are made by mix¬ ing whiting with the common glovers fize, and laying it on the paper with a proper brufh in the mod even manner. This is all that, is required, where the ground is to be left white; and the paper being then hung on a proper frame, till it be dry, is fit to be painted. When coloured grounds are required, the fame method muft be purfued, and the ground of whiting firft laid; except in pale colours, fuch as ftraw- colours or pink, where a fecond coating may fome- times be fpared, by mixing fome ftrong colour with the whiting. Manner of■ painting the PAVER-Hangings.—There are three methods by which paper-hangings are paint¬ ed ;*the firft by printing on the colours ; the fecond by ufing the fenc'd; and the third by laying them on^ with a pencil) as in other kinds of painting. Paper. When. Paper, PAP [ 38 When the colours are laid on by printing, the im- preffion is made by wooden prints; which are cut in fuch manner, that the figure to be expreffed is made to project from the furface by cutting away all the other part; and this, being charged with the colours tempered with their proper vehicle, by letting it gent¬ ly down on a block on which the colour is previoufly fpread, conveys it from thence to the ground of the paper, on which it is made to fall more forcibly by means of its weight, and the effort of the arm of the perfon who ufes the print. It is eafy to conclude, that there muft be as many feparate prints as there are colours to be printed. But where there are more than one, great care muft be taken, after the firft, to let the print fall cxadfly in the fame part of the paper as that which went before ; otherwife the figure of the defign would be brought into irregularity and confuflon. In common paper of low price, it is ufual, therefore, to print only the outlines, and lay on the reft of the colours by ftencilling ; which both faves the expence of cutting more prints, and can be praftifed by com¬ mon workmen, not requiring the great care and dex¬ terity neceffary to the ufing feveral prints. < The manner of pencilling the colours is this. The figure, which all the parts of any particular colour make in the defign to be painted, is to be cut out, in a piece of thin leather or oil-cloth, which pieces of leather or oil-cloth, are called Pencils; and being laid flat on the flieets of paper to be printed, fpread on a table or floor, are to be rubbed over with the colour, properly tem¬ pered, by means of a large brufh. The colour palling over the whole is confequently fpread on thofe parts of the paper where the cloth or leather is cut away, and give the fame effeft as if laid on by a print. This is neverthelefs only pradlicable in parts where there are only detached maffes or fpots of colours: for where there are fmall continued lines, or parts that run one into another, it is difficult to preferve the connexion or continuity of the parts of the cloth, or to keep the fmaller corners clofe down to the paper; and therefore, in fuch cafes, prints are preferable. Stencilling is in¬ deed a cheaper method of ridding coarfe work than printing: but, without fuch extraordinary attention and trouble as render it equally difficult with printing, it is far lefs beautiful and exaft in the effedf. For the outline of the fpots of colour want that fharpnefs and regularity that are given by prints, befides the fre¬ quent extralineations, or deviations from the juft figure^ which happens by the original mifplacing of the ften- eils, or the fhifting the place of them during the ope¬ ration. Pencilling is only ufed in the cafe of nicer work, fuch as the better imitations of the India paper. It is performed in the fame manner as other paintings in water or varnifh. It is fometimes ufed only to fill the outlines already formed by printing, where the price of the colour, or the exa&nefs of the manner in which it is required to be laid on, render the ftencilling or printing it lefs proper ; at other times, it is ufed for forming or delineating fome parts of the defign, where a fpirit of freedom and variety, not to be had in print¬ ed outlines, are defired to be had in the work. Management of the Flock Paper.—The paper de- figned for receiving the flock is firft prepared with a var- aiih-ground with fome proper colour, or by that of the. >1 ] PAP paper itfelf. It is frequently pra&ifed to print fome Paper. Mofaic, or other fmall running figure in colours, on the ground, before the flock be laid on ; and it may be done with any pigment of the colour defired, tem¬ pered with varnifli, and laid on by a print cut corre- fpondently to that end. The method of laying on the flock is this. A wooden print being cut, as is above deferibed, for laying on the colour in fuch manner, that the part of the defign which is intended for the flock may projeft beyond the reft of the furface, the varnilh is put on a block covered with leather or oil-cloth, and the print is to be ufed alfo in the fame manner, to lay the varnifh on all the parts where the flock is to be fixed. The fheet, thus prepared by the varnifhed impreffion, is then to be removed to another block or table; and to be ftrew- ed over with flock ; which is afterwards to be gently comprefled by a board, or fome other flat body, to make the varnifh take the better hold of it: and then the fheet is to be hung on a frame till the varnifh be perfeftly dry; at which time the fuperfluous part of flock is to be brufhed off by a foft camel’s-hair brufh; and the proper flock will be found to adhere in a very ftrong manner. The method of preparing the flock is, by cutting- woollen-rags, or pieces of cloth with the hand, by means of a large bill or chopping knife; or by means of a machine worked by a horfe-mill. There is a kind of counterfeit flock-paper, which, when well managed, has very much the fame effedl to the eye as the real, though done with lefs expence. The manner of making this fort is* by laying a ground of varnifh on the paper; and having afterwards print¬ ed the defign of the flock in varnilh, in the fame man¬ ner as for the true ; inftead of the flock, fome pig¬ ment, or dry colour, of the fame hue with the flock required by the defign, but fomewhat of a darker fhade, being well powdered, is ftrewred on the printed varnifh; and produces nearly the fame appearance. PAPER-^ey, is a term frequently made ufe of for bank-bills, which pafs currently in trade inftead of gold and filver. Concerning this fpecies of currency, the national mility of which has been controverted by fome, w'e have the following obfervations in Dr Smith’s Treatifa on the Wealth of Nations: “ The fubftitution of paper in the room 'of gold and filver money replaces a very expenfive inftrument of commerce w’ith one much lefs coftly, and fometimes equally convenient. Circulation comes to be carried on by a new wheel, which it colts kfs both to ere& and maintain than the old one. “ When the people of any particular country have fuch confidence in the fortune, probity, and prudence of a particular banker, as to believe that he is always ready to pay upon demand fuch of his promiflory notes as are likely at any time to be prefented to him, thofe notes come to have the fame currency as gold and fil¬ ver money, from the confidence that fuch money can at any time be had for them, “ A particular banker lends among his cuftomers his own promiflbry notes, to the amount, we fhallfup- pofe, of 100,000 1. As thofe notes ferve all tiie pur- pofes of money, his debtors pay him the fame intereft- as if he had lent them fo much money. This intereft is the fourceofhis gain. Though fome of thofe notes are- Paper. P PAP [ 5852 1 PAT? are continually coming back upon him for payment, part of them continue to circulate for months and years together. Though he has generally in circulation, therefore, notes to the amount of 100,000 1. 20,cool, in gold and filver may frequently be a fufficient pro- vifion for anfwering occafional demands. By this ope¬ ration, therefore, 20,000 1. in gold and filver perform all the fun&ions which 100,0001. could othervvife have performed. Eighty thoufand pounds of gold and fil¬ ver can therefore, in this manner, be fpared from the circulation of the country; and if different operations of the fame kind fhould, at the fame time, be carried on by many different banks and bankers, the whole circulation may be thus condufted with a fifth part only of the gold and filver. “ Let us fuppofe, for example, that the whole cir¬ culating money of fome particular country amounted, at a particular time, to 1,000,000 fterling, that fum being then fufficient for circulating the whole annual produce of their land and labour. Let us fuppofe too, that, fome time thereafter, different banks and bankers iffued promiffory notes, payable to the bearer, to the extent of t,000,000, referving in their different coffers 200,0001. for anfwering occafional demands. There would remain, therefore, in circulation 8oo,oool. in gold and filver, and 1,000,000 of bank-notes, or 1,800,OOO1. of paper and money together. But the annual produce of the land and labour of the country had before required only 1,000,000 to circulate and diftribute it to its proper confuraers, and that annual produce cannot be immediately augmented by thofe operations of banking. One million, therefore, will be fufficient to circulate it after them. The goods to be bought and fold being precifely the fame as before, the fame quantity of money will be fufficient for buy¬ ing and felling them. The channel of circulation, if 1 may be allowed fuch an expreffion, will remain pre¬ cifely the fame as before. One million we have fup- pofed fufficient to fill that channel. Whatever, there¬ fore, is poured into it beyond this fum, cannot run in it, but mufl overflow. One million eight hundred thoufand pounds are poured into it. Eight hundred thoufand pounds, therefore, muft overflow, that fum being over and above what can be employed in the cir¬ culation of the country. But though this fum cannot be employed at home, it is too valuable to be allowed to lie idle. It will therefore be fent abroad, in order to feek that profitable employment which it cannot find at home. But the paper cannot go abroad; be- caufe, at a diftance from the banks which iflue it, and from the country in which payment of it can be ex¬ acted by law, it will not be received in Common pay¬ ments. Gold and filver, therefore, to the amount of 8oo,oool. will be fent abrqad, and the channel of home circulation will remain filled with t,000,000 of paper, inftead of 1,000,000 of thofe metals which filled it be¬ fore. “ But though fo great a quantity of gold and fil¬ ver is thus fent abroad, we muft not imagine that it is fent abroad for nothing, or that its proprietors make a prefent of it to foreign nations. They will exchange it for foreign goods of fome kind or another, in order to fupply the confumption either of fbme other foreign country or of their own. - “ If they employ it in purchafing goods in one fo¬ reign country in order to fupply the confumption of Paper. another, or in what is called the carrying trade, what- ever profit they make will be an addition to the neat revenue of their own country. It is like a new fund, created for carrying on a new trade; domeftic bufinefs being nowtranfa&ed by paper, and the gold and filver being converted into a fund for this new trade. “ If they employ it in purchafing foreign goods for home-confumption, they may either firft purchafe fuch goods as are likely to be confumed by idle people who produce nothing, fuch as foreign wines, foreign filks, &c.; or, fecondly, they may purchafe an additional ftock of materials, tools, and provifions, in order to employ an additional number of induftrious people, who re-produce, with a profit, the value of their an¬ nual confumption. , “ So far as it is employed in the firft way, it pro¬ motes prodigality, increafes expence and confumption, without increafing produftion, or eftablifhing any per¬ manent fund for fupporting that expence, and is in every refpeft hurtful to the fociety. “ So far as it is employed in the fecond way, it promotes induftry ; and though it increafes the con- fumptiqn of the focicty, it provides a permanent fund for fupporting that confumption, the people who con- fume, re-prodircing, with a profit, the whole value of their annual confumption. The grofs revenue of the fociety, the annual produce of their land and labour, is increafed by the whole value which the labour of thofe workmen adds to the materials upon which they are employed; and their neat revenue by what re¬ mains of this value, after deducing what is neceflary for fupporting the tools and inftruments of their trade. ea' were cut off. But the inhabitants of Aroo, who refort yearly to Banda, undeceived the Dutch, and freed them from thofe prejudices. Another reafon for cutting off the legs is, that the birds are more eafily preferved , without them; befides that the Moors wanted the birds without legs, in order to put them on in their mock-fights as ornaments to their helmets. The in¬ habitants of Aroo, however, have brought the birds with legs for 70 or 80 years; and Pijafetta, fhipmate of Ferdinand Magellan, proved, about the year 1525, an eye-witnefs that thefe creatures were net without kgs. However, the peculiar length and ftructure of their fcapular feathers hinders them from fettling, in high winds, on trees; and when they are thrown on the ground by thefe winds, they cannot rife again. If taken by the natives, they are immediately killed, as their food is not known ; and they defend themfelves with great courage with their formidable bills. There are reckoned fix fpecies of thefe birds. 1. The largeft bird of Paradife is commonly two foot four inches in length ; the head is fmall; the bill hard and long, of a pale colour. The head and back- part of the neck is lemon-coloured, a little black about the eyes ; about the neck, the bird is of the brighteft gloffy emerald green, foft like velvet 5 as is alfo the breafi, which is black : the wings are large, and chef- nut-coloured; the back-part of the body is covered with long, ftraight, narrow feathers, of a pale brown colour, fimilar to the plumes of the oftrich. Thefe feathers are fpread when the bird is on the wing ; for which reafon he can keep very long in the air. On both fides of the belly are two tufts of ft iff and ihorter feathers, of a golden yellow, and (hining. From the rump proceed t.ro long ftiff ftiafts, which are feather¬ ed on their extremities. Thefe birds are not found in Key, an ifland fifty Dutch miles eaft of Banda ; but they are found at the Aroo iflands, lying 15 Dutch miles farther eaft than Key, during the wefterly or dry monfoon ; and they return to New Guinea as foon as the eafter- ly or wet monfoon fets in. They come always in a flock of 30 or 40, and are led by a bird which the inhabitants of Aroo call the king. This leader is black, with red fpots; and conftantly fties higher than the reft of the flock, which never forfake him, but ParadUia. fettle as foon as he fettles: a circumftance that fre- " quently proves their ruin when the king lights on the ground, whence they are not able to rife on account of the Angular ftruAure and difpefition of their plu¬ mage. They are likewife unable to fly with the wind, which would ruin their loofe plumage ; but take their flight conftantly againft it, cautious not to venture out in hard blowing weather, as a ftrong wind frequently obliges them to come to the ground. During their flight they cry like ftarlings. Their note, however, approaches more to the croaking of ravens; which is heard very plainly, when they are in diftrtfs from a frefh gale blowing on the back of their plumage. In Aroo, thefe birds fettle on the bigheft trees, efpe- cially on the ficus benjamina of the hortus naalaba- ricus, commonly called the 'waringa tree. The natives catch them with bird-lime or in noofes, or fhoot them, with blunt arrows ; but though fome are ftill alive when they fall into their hands, the catchers kill them immediately, and fometimes cut the legs off; then they draw out the entrails, dry and fumigate the bo¬ dies with fulphur or fmoke only, and fell them at Banda for half a rixdollar each ; but at Aroo they may be bought for a fpike-nail or a piece of old iron. Flocks of thefe birds are often feen flying from one ifland to the other againft the wind. In cafe they find the wind become too powerful, they fly ftraight up into the air, till they come to a place where it is kfs agitated, and then continue their flight. During the eaftern monfoon their tails are moulted, fo that they have them only during four months of the weflcm monfoon. 2. The froaller bird of Paradife is about 20 inches long. His beak is lead-coloured, and paler at; the point. The eyes are fmall, and inclofed in black about the neck. The head and back of the neck are of a dirty yellow ; the back of a greyifh yellow; the bread and belly of a dufky colour; the wings fmall, and ehefnut-coloured. The long plumage is about a foot in length,and paler than in the large fpecies; as in general the colours of this bird are kfs bright than the former. The two long feathers of the tail are conftamly thrown away by the natives.—This is in all refpe&s like the greater fort; and they likewife follow a king or leader, who is, however, blacker, with a purplish caft, and finer in colour than the reft. The neck and bill are larger in the male than in the female. They rooft on the topij of the higheft trees, and do not migrate like the other kind. Some fay, that the birds of this fpecies, find¬ ing themfelves weak through age, foar ftraight to¬ wards the fun till they are tired, and fall dead to the ground. The natives draw the entrajls, fear the birds with a hot iron, and put them in a tube of bamboo for prefervation. 3. and 4. The large black bird of Paradife ig brought without wings or kgs for fale ; fo that no ac¬ curate defeription of it hath yet been given. Its fi¬ gure, when fluffed, is narrow and round, but ftretch- ed in length to the extent of four fpans. The plu¬ mage on the neck, head, and belly, is black and vel¬ vet-like, with a hue of purple and gold, which ap¬ pears very ftrong. The bill is blackifh, and one inch in length. On both fides are two bunches of fea¬ thers, which have the appearance of wings, although PAR [ 5857 1 PAR Paradifea. they be very different, the wings being cut off by the na- tives. This plumage is foft, broad, fimilar to pea¬ cocks feathers, with a glorious glofs and greenilh hue, and all bent upwards ; which Valentine thinks is occa- fioned by the birds being kept in hollow bamboo reeds. The feathers of the tail are of unequal length ; thofe next to the belly are narrow, like hair; the two up- permoft are much longer, and pointed ; thofe imme¬ diately trader them are a fpan and a half longer than the upper ones; they are ftiff, on both fides fringed with a plumage like hair, black above, but gloffy be¬ low. Birds of this kind are brought only from one particular place of New Guinea. BeGdes the large black bird of Paradife, there is ftill another fort, whofe plumage is equal in length, but thinner in body, black above, and without any remarkable glofs, not having thofe fhiniug peacock-feathers which are found on the greater fpecies. This wants likewife the three long- pointed feathers of the tail belonging to the larger black fpecies. 5. The white bird of Paradife is the moll rare, and has two varieties; one quite white, and the other black and white. The former is very rare. Thefecondbas the fore-part black, and the back-part white ; with 12 crooked wiry (hafts, which are almoft naked, tho’, in fome places, covered with hairs. 6. In the year 1689, a new fpecies of the black bird of Paradife was feen in Amboyna. This was only one foot in length, with a fine purple hue, a fmall head, and a ftraight bill. On its back, near the wings, are feathers of a blue and purple colour, as on the other birds of paradife ; but under the wings, and over all the belly, they are yellow-coloured, as in the common fort: on the back of the neck they are moufe-coloured mixed with green. It is remarkable in this fpecies, that there are before the wings two roundifh tufts of feathers, which are green-edged, and may be moved at pleafure by the bird, like wings. Inftead of a tail, he has 12 or 13 black, naked, wire¬ like (hafts, hanging promifeuoufiy like feathers. His legs are ftrong, and have (harp claws. The head is remarkably fmall; and the eyes are alfo fmall, and fur- rounded with black. 7. The laft fpecies is the king’s bird. This crea¬ ture is about feven inches long, and fbmewhat larger than a titmoufe. Its head and eyes are fmall; the bill ftraight; the eyes included in circles of black plu¬ mage ; the crown of the head is flame-coloured; the back of the neck blood-coloured ; the neck and bread of a chefnut colour, with a ring of the brighteft eme¬ rald-green. Its wings are in proportion ftrong; and the quill-feathers dark, with red (hining plumes, fpots, and ftripes. The tail is ftraight, (hort, and brown. Two long naked black (hafts projeft from the rump, at lead a hand-breadth beyond the tail; having at their extremities femilunar twilled plumage, of the mod glaring green colour above, and dullcy below. The belly is white and green fprinkled ; and on each fide is a tuft of long plumage, feathered with a broad margin, being on one fide green, and on the other dufky. The back is blood-red and brown,--(hining like filk. The legs are in fize like thofe of a lark, three fore-toes, and one back-toe. This bird affo- ciates not with any of the other birds tjf paradife ; but (tits folitary from built to bu(h, wherever he fees red berries, without ever getting on tall trees. Paradox PARADOX, in philofophy, a propofition feem- ingly abfurd, as being contrary to fome received opi- ar32U3y‘ nions, but yet true in faft. No fcience abounds more with paradoxes than geo¬ metry: thus, that a right line (hould continually ap¬ proach to the hyperbola, and yet never reach it, is a true paradox ; and in the fame manner a fpiral may continually approach to a point, and yet not reach it in any number of revolutions, however great'.' PARAGOGE, in grammar, a figure whereby a letter or fyllable is added to the end of a word; as med, for me; dicier, for did, &c. PARAGRAPH, in general, denotes a fe6tion or divifion of a chapter; and in references is marked thus, PARAGUAY, or La Plata, a province of Spa- nifh America, bounded on the north by the river of the Amazons ; on the eaft, by Brafil; on the fouth, by Patagonia ; and on the weft, by Chili. This coun¬ try was firft difeovered by Sebaftian Cabot, who, in 1526, paffed from Rio de la Plata to the river Parana in fmall barks, and thence entered the river called Pa¬ raguay. It was not, however, thoroughly reduced till the Jefuits obtained poffeffion of it. A few of thefe went to Paraguay, foon after the city of Affumption was founded, and converted about 50 Indian families, who foon induced many others to follow their example, on accoutit of the peace and tranquillity they enjoyed under the fathers. They had long refilled the Spa¬ niards and Portuguefe ; but the Jefuits, by learning their language, conforming to their manners, &c. foon acquired great authority among them ; till at laft, by fteadily purfuing the fame artful meafures, they arri¬ ved at the higheft degree of power and influence, be¬ ing in a manner the abfolute fovereigns of a great part of this extenfive country; for above 350,000 families are faid to have been fubjeft to them, living in obedi¬ ence and awe bordering on adoration, yet procured without the lead violence or conftraint. There were above 60,000 parifties on the banks of the rivers Pa¬ raguay and Parana, not exceeding the diflance of 3a miles from each other: in each of thefe there was a Jefuit, fupreme in all caufes, civil, military, and ec- clefiaftic, who might be regarded as a petty prince, governing not only with the fway of a fovereign, but with the influence and reputation of an oracle. He nominated the chiefs in all the different departments : the cacique held of him ; the general received hiscom- miflion and inftrudlions from him ; and all his deci- fions were without appeal. The fame reverend father who prefided over the civil ceconomy, affifted by two others, performed alfo the duties of a parilh-prieft ; catechiting the Indians, faying mafs, exhorting, mar¬ rying, impofing penance, vifiting the fick, &c. The above was the account given of the behaviour of the Jefuits by their own writers. Others, however, treated their charadlers with more feverity; accufing them of pride, haughtinefs, and abufing their autho¬ rity to the greateft degree; infomuch that they would have caufed the magistrates to be whipped in their pre¬ fence, and obliged perfons of the highefl diftindion within their jurifdidion to kifs the hem of their gar¬ ment, as the greateft honour at which they could pof- fibly arrive.

PARK, (French parque, i. e. locus inclufus), is a large quantity of ground inclofed and privileged for wild beads of chafe, by the king’s grant or prefcrip- tion. See Chase and Forest. Manwood defines a chafe to be “ a privileged place for beads of venary, and other wild beafts of the fo- reft and chafe, tam Sylvejlres, quam Capipejlresand differs from a chafe or warren, in that it muft be inclo¬ fed: for if it lies open, it is good caufe of feizure into the king’s hands, as a thing forfeited: as a free chafe is, if it be inclofed: befides, the owner cannot have an a&ion againft fuch as hunt in his park, if it lies open. No man can eredt a park without licence under the broad feal; for the common law does not encourage matter of pleafure, which brings no profit to the com¬ monwealth. But there may be a park in reputation, ere&ed without any lawful warrant; and the owner may bring his aftion againft perfons killing his deer. To a park three things are required. 1. A grant thereof. 2. Inclofures by pale, wall, or hedge. 3. Beafts of a park; fuch as the buck, doe, &c. And where all the deer are deftroyed, it ftiall no more be accounted a park; for a park con fills of vert, venifon, and inclofure; and if it is determined in any of them, it is a total difparking. Parks as well as chafes are fubjeft to the common law, and are npt to be governed by the foreft laws. Park, as connedled with gardening. See Garden¬ ing. A park and a garden are more nearly allied than a * See Farmhrm and a garden *, and can therefore be accommo- snd Gar- dated to each other without any difparagement to ei- cening. tjjeri farm j0fes fomc 0f jts charafteriftic proper¬ ties by the connexion, and the advantage is on the part of the garden ; but a park thus bordered retains all its own excellencies; they are only enriched, not counteradted, by the intermixture. The moft perfect compofition of a place that can be imagined, confifts of a garden opening into a park, with a ftiort walk through the latter to a farm, and ways along its glades to ridings in the country: but to the farm and the ri- P A R dings the park is no more than a paflage; and its woods Park, and its buildings are but circumftances in their views;■=_ its feenes can be communicated only to the garden. The affinity of the two fubjedts is fo clofe, that it would be difficult to draw the exaft line of feparation between them. Gardens have lately encroached very much both in extent and in ftyle on the chara&er of a park ; but ftill there are feenes in the one which are out of the reach of the other. The fmall fequeftrated fpots which are agreeable in a garden would be trivial in a park; and the fpacious lawns which are among the. nobleft features of the latter, would in the former fa¬ tigue by their want of variety; even fuch as, being of a moderate extent, may be admitted into either, will feem bare and naked, if not broken in the one ; and lofe much of their greatnefs, if broken, in the other. The proportion of a part to the whole is a meafure of its dimenfions: it often determines the proper fize for an objedt, as well as the fpace fit to be allotted to a feene ; and regulates the ftyle which ought to be af- figned to either. But whatever diftindlions the extent may occafion between a park and a garden, a ftate of highly culti¬ vated nature is confiftent with each of their charadters; and may in both be of the fame kind, though in dif¬ ferent degrees. The excellencies both of a park and of a garden are happily blended at Hagley (a), where the feenes are equally elegant and noble. It is fituated in the midll of a fertile and lovely country, between the Clent and the Witchberry hills; neither of which are within the pale, but both belong to the place. The latter rife in three beautiful fwells. One of them is covered with wood; another is an open {beep-walk, with an obelilk on the fummit; on the third, the portico of the temple of Thefeus, exadtly on the model of that at Athens, and little lefs in the dimenfions, Hands boldly out upon the brow, backed by the dark ground of a fir planta¬ tion, and has a moft majeftic appearance above the fteeps which fall before and befide it. The houfe is feen to the greateft advantage from thefe eminences, and every point of them commands fome beautiful pro- fpedt. The bufy town of Stourbridge is juft below them; the ruins of Dudley caftle rife in theofflkip; the coun¬ try is full of induftry and inhabitants; and a fmall por¬ tion of the moor, where the minerals, manufactured in the neighbourhood, are dug, breaking in upon the ho¬ rizon, accounts for the richnefs, without derogating from the beauty, of the landfcape. From the Clent hills the views are ftill greater; they extend on one fide to the black mountains in Wales, a long ridge which ap¬ pears, at 60 miles diftance, in the interval between the unweildy heap of the Malvern hills, and the folitary peak of the Wrekin, each 30 miles off, and as many afunder. The fmoak of Worcefter, the churches in Birmingham, and the houfes in Stourbridge, are di- ftin&ly vifible. The country is a mixture of hill and dale, and ftrongly inclofed; except in one part, where a heath, varied by rifing grounds, pieces of water, and feveral obje&s, forms an agreeable contrail to the cul¬ tivation which furrounds it. From the other extre¬ mity of the Clent hills, the profpedl is lefs extenfive; but the ground is more rude and broken : it is often overfpread with large and beautiful woods ; and the view is dignified with numerous feats.

In one of thefe hollows is built a neat cottage, under a deep defcent, flickered befides by plantations, and prefenting ideas of retirement in the midft of fo much open expofure; from the heights above it, is feen all that view which before was commanded from the Witchberry hills, but which is feen here over Hagley park; a noble fore-ground, beautiful in itfelf, and com¬ pleting the landfcape. The houfe, though low in the park, is yet above the adjacent country, which it overlooks to a very diftant horizon. It is furrounded by a lawn of fine uneven ground, and diverfified with large clumps, little groupes, and Angle trees. It is open in frost, but covered on one fide by the Witchberry hills; on the other fide, and behind, by the eminences in the park, which are high and deep, and all overfpread with a lofty hanging wood. The lawn prefling to the foot, or creeping up the (lopes of thefe hills, and fometimes winding along glades into the depth of the wood, traces a beautiful outline to a fylvan fcene, already rich to luxuriance in maffinefs of foliage and ftatelincfs of growth. But though the wood appears to be entire, it in rea¬ lity opens frequently into lawns, which occupy much of the fpace within it. In the number, the variety, and the beauty of thefe lawns, in the (hades of the feparations between them, in their beauties alfo, and their varieties, the glory of Hagley confifts. No two of the openings are alike in dimenfions, in fhape, or in charadler. One is of no more than five or fix acres; another of not lefs than fifty; and others are of all the intermediate fixes. Some ftretch out into lengthened glades ; fome widen every way: they are again diftinguiflied by buildings, by profpe&s, and often by the ftyle only of the plan¬ tations around them. The boundary of one is deferi- bed by a few carelefs lines; that of another is compo- led of many parts, very different and very irregular: and the ground is never flat; but falls fometimes in deep defeents, fometimes in gentle declivities waves along eafy fwells, or is thrown into broken inequalities, with tndlefs variety. An oftagon feat, facred to the memory of Thomfon, snd erected on his favourite fpot; (lands on the brow of a deep; a mead winds along the valley beneath, till it is led on either hand behind fome trees. Oppofite to the feat, a noble wood crowns the top, and feathers down to the bottom of a large, oval, fwelling hill. As it defeends on one fide, the didant country becomes the offtkip. Over the fall, on’the other fide, the Clent hills appears. A dufley antique tower fiands jud below them, at the extremity of the wood ; and in the midd of it is feen a Doric portico, called Pope's Build¬ ing, with part of the lawn before it. The fcene is very Ample: the principal features are great; they prevail over all the red, and are intimately connected with each other. The next opening is fmall, circling about a rotunda on a knole, to the foot of which the ground rifes every way. The trees which furround it,are large; but their foliage is not very thick ; and their dems appearing beneath, their ramifications between the boughs are, in fo confined a fpot, very diftinguiflied and agreeable circumdances. It is retired; has no profpe&; novifible Park- outlet but one, and that is (hort and narrow, to a bridge with a portico upon it, which terminates a piece of water. The grove behind the rotunda feparates this from a large, airy, fored glade, thinly (kirted with wood, carelefs of drefs, and much overgrown with fern. The. wildnefs is an acceptable relief in the midd of fo much elegance and improvement as reign in the neighbour¬ ing lawns; and the place is in itfelf pleafant; in no part confined; and from a Gothic feat at the end is a perfpe&ive view of that wood and tower which were feen before in front, together with the Witchberry hills, and a wide range of country. The tower, which in profpeft is always connefled with wood, (lands however on a piece of down, which dretches along the broad ridge of a hill, and fpreads on each hand for fome way down the Tides. Thick groves catch the falls. The defcent on the right is foon lod under the trees; but that on the left being deeper and (hotter, it may be followed to the bottom. A wood hangs on the declivity, which is continued in the val¬ ley beneath. The tower overlooks the whole: it feems the remains of a cadle, partly entire, partly in ruins, and partly overgrown with buflies. A finer fituatioiv cannot be imagined: It is placed in an expofed unfre¬ quented fpot; commands an extenfive profpedt; and is every where an intereding objed. At the end of the valley below it, in an obfeure cor¬ ner, and diut out from all view, is a hermitage, com- pofed of roots and of mofs: high banks, and a thick covert darkened with horfe-chefnuts, confine the fe- quedered fpot: a little rill trickles through it, and two fmall pieces of water occupy the bottom. They are feen on one fide through groupes of trees; the other is open, but covered with fern. This valley is the extre¬ mity of the park ; and the Clent hills rife in all their irregularity immediately above it. The other defcent from the cadle is a long declivi¬ ty, covered like the red with noble woods, in which fine lawns are again embofomed, differing dill from the former, and from each other. In one, the groundr is very rough, the boundary is much broken, and marked only by the trunks of the trees which (hoot up high before the branches begin. The next is more, fimple ; and the ground falls from an even brow into one large hollow, which (lopes towards the glen, where it finks into the covert. This has a communication thro’ a (hort glade, and between two groves, with ano¬ ther called the Tinian lanun, from the refemblance which it is faid to bear to thofe of that celebrated ifland : it is encompaffed with the datelied trees, all frefli and vigorous, and fo full of leaf, that not a dem, not a branch, appears, but large maffes of foliage on¬ ly deferibe an undulating outline : the effed, however, is not produced by the boughs feathering down to the bottom ; they in appearance (hoot out horizontally, a few feet above the ground, to a furprifing didance, and form underneath an edging of (hade, into which the retreat is immediate at every hour of the day. The ver¬ dure of the turf is as luxuriant there as in the open fpace: the ground gently waves in both over eafy fwells and little dips, jud varying, not breaking, the furface. No drong lines are drawn ; no driking ob- je&s are admitted; but aU k of an even temper, all mild,. PAR [ 5870 ] PAR „ mild, placid, and ferene; In the gayefl feafon of the day not more than cheerful, in the ftilleft watch of night not gloomy. The fcene is indeed peculiarly adap¬ ted to the tranquillity of the latter, when the moon feems to repofe her light on the thick foliage of the grove, and fteadily marks the (hade of every bough. It is delightful then to faunter here, and fee the grafs, and the goflamer which entwines it, gliftening with dew ; to liften and hear nothing ftir, except perhaps a withered leaf dropping gently through a tree ; and, fheltered from the chill, to catch the frefhnefs of the evening air: a folitary urn, chofen by Mr Pope for the fpot, and now infcribed to his memory, when fhewn by a gleam of moon-light through the trees, fixes that thoughtfulnefs and compofure to which the mind is infenfibly led by the reft of this elegant fcene. The Doric Portico, which alfo bears his name, tho’ not within fight, is near: it is placed on the declivity of a hill; and Thomfon’s feat, with its groves and appendages, are agreeable circumftances in the profpedl before it. In the valley beneath is fixed a bench, which commands a variety of (hort views; one is up the afcent to the portico, and others thro’ openings in the wood to the bridge and the rotunda. The next lawn is large : the ground is fteep and ir¬ regular, but inclines to one dire&ion, and falls from every fide into the general declivity: the outline isdi- verfified by many groupes of trees pn the flopes ; and frequent glimpfes of the country are feen in perfpec- tive through openings between them. In the brow is a feat, in the proudeft fituation of all Hagley ; it com¬ mands a view down the bold fweep of the lawn, and over a valley filled with the nobleft trees, up to the heights beyond. One of thofe heights is covered with a hanging wood ; which opens only to fhew Thom¬ fon’s feat, and the groves and the fteeps about it: the others are the Witchberry hills, which fefm to prefs forwatd into the landfeape ; and the mafiy heads of the trees in the vale, uniting into a continued furface, form a broad bafe to the temple of Thefeus, hide the fwell on which it is built, and crowd up to the very foundation. Farther back ftands theobelifk; before it is the fheep-walk ; behind it the Witchberry wood. The temple is backed by the firs ; and both thefe plan¬ tations are conne&ed with that vaft fylvan fcene, which overfpreads the other hill, and all the intermediate valley. Such extent of wood; fuch variety in the dif- pofition of it; objefts fo illuftrious in themfelves, and ennobled by their fituations, each contrafted to each, every one didinS, and all happily united : the parts fo beautiful of a whole fo great, feen from a charm¬ ing lawn, and furrounded by a delightful country, compofe all together a fcene of real magnificence and grandeur. The feveral lawns are feparated by the fineft trees ; which fometimes grow in airy groves, chequered with gleams of light, and open to every breeze; but more frequently, whofe great branches meeting or eroding each other, call a deep impenetrable fha'de. Large boughs feathering down often intercept the fight; or a vacant fpace is filled with coppice-wood, nut, haw¬ thorn, and hornbeam, whofe tufted heads mixing w ith the foliage, and whofe little ftems cluftering about the trunks of the trees, thicken and darken the planta¬ tion. Here and there the divifion is of fuch coppice- Park. wood only, which then being left conftrained and op- preffed, fprings up ftronger, fpreads further, and joins in a low vaulted covering: in other places the fhade is high, over-arched by the tailed alb, or fpreads under the branches of the mod venerable oaks. They rife in every (hape, they are difpofed in every form in which trees can grow. The ground beneath them is fome¬ times almoft level; fometimes a gentle fwell; but ge¬ nerally very irregular and broken. In feveral places, large hollows wind down the fides of the hills, worn in the ftormy months by water-courfes, but worn many ages ago. Very old oaks in the midft of the channels prove their antiquity : fome of them are per- fe&ly dry moft part of the year ; and fome are water¬ ed by little rills all the fummer: they are deep and broad ; the fides are commonly fteep ; often abrupt and hollow; and the trees on the bank fometimes ex¬ tend their roots, all covered with mofs, over the chan¬ nels of the water. Low down in one of thefe glens, under a thick fliade of horfe-chefnuts, is a plain bench, in the midft of feveral little currents and water-falls, running among large loofe ftones, and the ftumps of dead trees, with which the ground is broken. On the brink of another glen, which is diftinguilhed by a numerous rookery, is a feat in a ftiil wilder fituation, near a deeper hollow, and in a darker gloom: the falls are nearly perpendicular; the roots of fome of the trees are almoft bare, from the earth having crumbled away ; large boughs of others, finking with their own weight, f*em ready to break from the trunks they belong to; and the fineft a(h, ftill growing, lie all aflant the water-courfe below, which, tho’ the ^ftream runs in winter only, yet conftantly retains the black tinge of damp, and cafts a chill all around. Gravel-walks are condufted acroft the glens, thro* the woods, the groves,|or the thickets, and along the fides of the lawns, concealed generally from the fight, but always ready for the communication, and leading to the principal feenes. The frequency of thefe walks, the number and the ftyle of the buildings, and the high prefervation in which all the place is kept, give to the whole park the air of a garden. There is, however, one fpot more peculiarly adapted to that purpofe, and mere artificially difpoled than the reft; it is a narrow vale, divided into three parts: one of them is quite filled with water, which leaves no room for a path, but thick trees on either fide come down quite to the brink ; and between them the fight is conduced to the bridge with a portico upon it, which clofes the view : another part of this vale is a deep gloom, over¬ hung with large afti and oaks, and darkened below by a number of yews : thefe are fcattered over very uneven ground, and open underneath ; but they are encompaffcd by a thick covert, under which a ftream falls, from a Itony channel, down a rock ; other rills drop into the current, which afterwards pours over a fecond cafcade into the third divifion of the vale, where it forms a piece of water, and is loft under the bridge. The view from this bridge is a perfect opera fcene, through all the divifions of the vale, up to the rotunda. Both thefe buildings, and the other decora¬ tions of the fpot, are of the ipecies generally confined to a garden. The hermitage alfo, which has been de- feribed, and its appendages, are in a ftjde which does not PAR Park, not fce!oT?g to a park ; but through all the reft of the F‘‘^ker^ place, the two charafters are intimately blended. The whole is one fubjett ; and it was a bold idea to con¬ ceive that one to be capable of fo much variety ; it re¬ quired the mod vigorous efforts of a fertile fancy to carry that idea into execution.

PARKER (Matthew), the fecond Protedant arch- bidiop of Canterbury, was born at Norwich in the year 1504, the 19th of Henry VII. His father, who was a man in trade, died when our author was about 12 years old ; but his mother took fpecial care of his education, and at the age of 17 fent him to Corpo*- Chrifti college in Cambridge, where, in 1523, he took his bachelor’s degree. In 1527 he was ordained, crea¬ ted mader of arts, and chofen fellow of the college. Having obtained a licence to preach, he frequently- held forth at St Paul’s crofs in London, and in other parts of the kingdom, jin 1533 or 1534, he was made chaplain to queen Anne Boleyn, who- obtained for him the deanry of Stoke-Clare in Suffolk, where he founded a grammar-fchool. After the death of the queen, king Henry made him his own chaplain, and in 1541, prebendary of Ely. In 1544, he was, by the king’s command, elefted mader of Corpus-Chridi college, and the following year, vice-chancellor of the univerfity. In 1547, he lod the deanry of Stoke, by the diffolution of that college. In the fame year he married the daughter of Robert Harleftone, a Nor¬ folk gentleman. In the year 1552, he was nominated, by Ed¬ ward VI. to the deanry of Lincoln, which, with his other preferments, enabled him to live in great af¬ fluence : but the Papift Mary was hardly feated on the throne, before he was deprived of every thing he held in the church, and obliged to live in obfcurity, frequently changing his place of abode to avoid the fate of the other reformers. Queen Elizabeth afcended the throne in 1558; and in the following year Dr Parker, from indigence and obfcurity, was at once raifed to the fee of Canterbury, an honour which he neither folicited nor defired. In this high ftation he afted with fpirit and propriety. He repaired and beautified his palace at Lambeth at a vaft expence; founded feveral fcholarlhips in Bennet or Corpus-Chrifti college in Cambridge, and gave large prefents of plate to that and to other colleges in this univerfity. He gave 100 volumes to the public library. He likewife founded a free-fchool at Roch¬ dale in Lancalhire. He took care to have the fees fiHed with pious and learned men ; and, confidering the great want of hibles in many places, he, with the afiiftance of other learned men, improved the Engliih tranflatiOn, had it printed on a large paper, and dif- perfed through the kingdom. This worthy prelate died in the year 1575', aged 72, and was buried in his own chapel at Lambeth.

PARLEY", a conference with an enemy. Hence, to beat or found a parley, is to give a fignal for holding fuch a conference by beat of drum, or found of trumpet. PARLIAMENT, the grand affembly of the three ftates of this kingdom, fummoned together by the king’s authority, to confider of matters relating to the public welfare, and particularly to enad and repeal laws. The original or firft inftitution of parliaments is one of thofe matters which lie fo far hidden in the dark ages of antiquity, that the tracing of it out is a thing equally difficult and uncertain. The word parliament itfelf (or colloquium, as fome of our hiftorians tranflate it) is, comparatively, of modern date ; derived from the French, and fignifying the place where they met and conferred together. It was firft applied to general af- femblies of the ftates under Louis VII. in France, about the middle of the 12th century. But it is cer¬ tain, that, long before the introdudion of the Nor¬ man language into England, all matters of importance were debated and fettled in the great councils of the realm. A pradice which feems to have been univer- fal among the northern nations, particularly the Ger¬ mans ; and carried by them into all the countries of Europe, which they over-ran at the diffolution of the Roman empire. Relics of which conftitution, under various modifications and changes, are ftiil to be met with in the diets of Poland, Germany, and Sweden, and the affembly of the eftates in France ; for what is there now called the parliament is only the fupreme court of juftice, confifting of the peers, certain digni¬ fied ecclefiaftics, and judges; which neither is in prac¬ tice, nor is fuppofed to be in theory, a general coun¬ cil of the realm. With us in England, this general council hath been held immemorially, under the feveral names of michel- Jynoth, or “ great council,” michel-gernote, or “ great meeting,” and more frequently wittena~gemote, or “ the meeting of wife men.” It was alfo ftyled in Latin, commune concilium reg?ii, magnum concilium re- gir, curia magna, convent us magnatum vel procerum, affageneralis, and fometimes cornmuniias regni Anglise. We have inftances of its meeting to order the affairs of the kingdom, to make new laws, and to amend the old, or, as Fleta expreffes it, novis injuriis emerfs no¬ va confituere remedia, fo early as the reign of Ina king of the weft Saxons. Offa king of the Mercians, and Ethelbert king of Kent, in the feveral realms of the heptarchy. And, after their union, the Mirrour informs us, that king Alfred ordained for a perpetual ufage, that theft councils fheuld meet twice in the year, or oftener, if need be, to treat of the govern¬ ment of God’s people ; how they fhonld keep them- felves from fin, fhould live in quiet, and fhould receive right. Our fucceeding Saxon and Danifli monarehs held frequent councils of this fort, as appears from their refpeflive codes of laws ; the titles whereof ufual- ly fpeak them to be enafted, either by the king with the advice of his wittena-gemote, or wife men, as, 33 D Hac C 5871 ] PAR [ 5872 ] PAR Parliament.

There is alfo no doubt but thefe great councils were occafionally held under the firft princes of the Norman line. Glanvil, who wrote in the reign of Henry II. fpeaking of the particular amount of an amercement in the fheriff’s court, fays, it had never yet been af- certained by the general affize, or aflembly, but was left to the cuftom of particular counties. Here the general affize is fpoken of as a meeting well known, and its ftatutes or decifions are put in a manifelt con- tradiftinftion to cuftom, or the common law. And in Edward Ill’s time an aft of parliament, made in the reign of William the Conqueror, was pleaded in the cafe of the abbey of St Edmund’s-bury, and judicially allowed by the court. Hence it indifputably appears, that parliaments, or general councils, are coeval with the kingdom itfelf. How thofe parliaments were conftituted and compo- fed, is another queftion, which has been matter of great difpute among our learned .antiquarians; and particularly, whether the commons were fummoned at all; or, if fummoned, at what period they began to form a diflinft aflembly. But without entering into controverfies of this fort, it may be fufficient to ob- ferve, that it is generally agreed, that in the main the conftitution of parliament, as it now ftands, was mark¬ ed out fo long ago as the 17th year of king John, A. D. 1215, in the great charter granted by that prince; wherein he promifes to fummon all arch- bilhops, biftiops, abbots, earls, and greater barons, perfonally; and all other tenants in chief under the crown, by the ftieriff and bailiffs; to meet at a certain place, with 40 days notice, to affefs aids and fcutages when neceffary. And this conftitution has fubfifted in fad at leaft from the year 1266, 49 Hen. III. there being ftill extant writs of that date, to fummon knights, citizens, and burgeffes, to parliament. We proceed therefore to inquire wherein cpnfifts this con- flitution of parliament, as it now ftands, and has flood for the fpace of at leaft 500 years. And in the pro- fecution of this inquiry, we ftiall confider, firft, The manner and time of its affembling: Secondly, Its con- ftituent parts: Thirdly, The laws andjcuftoms relating to parliament: Fourthly, The methods of proceeding, and of making ftatutes, in both houfes: And, laftly. The manner of the parliament’s adjournment, proroga¬ tion, and diffolution. I. Hs to the manner and ti?ne of ajfemhling. The parliament is regularly to be fummoned by the king’s writ or letter, iffued out of chancery by advice of the privy-council, Jft leaft 40 days before it begins to fit. It is a branch of the royal prerogative, that no par¬ liament cah be convened by its, own authority, or by the authority of any, except the king alone. And this prerogative is founded upon very good reafon. For, fuppofing it had a right to meet fpontaneoufly, with¬ out being called together, it is impofiible to conceive that all the members, and each of the houfes, would agree unaniinoufly upqn the proper time and place of meeting: and if half of the members met, and half Parliament, abfented themfelves, who fhall determine which is real- ly the legiflative body, the part affembled, or that which flays away? It is therefore neceffary, that the parliament fhould be called together at a determinate time and place; and, highly becoming its dignity and independence, that it fhould be called together by none but one of its own conftituent parts: and, of the three conftitnent parts, this office can only appertain to the king; as he is a fingle perfou, whofe will may be uniform and fteady; the firft perfon in the nation, being fuperior to both houfes indignity ; and the on¬ ly branch of the legiflature that has a f.parate exift- ence, and is capable of performing any adt at a time when no parliament is in being. Nor is it an excep¬ tion to this rule, that, by fome modern ftatutes, on the demife of a king or queen, if there be then no parlia¬ ment in being, the laft parliament revives, and is to fit again for fix months, unlefs diffolved by the fucceffor: for this revived parliament mull have been originally fummoned by the crown. It is true, that the convention-parliament which re- ftored king Charles II. met above a month before his return; the lords by their own authority, and the com¬ mons in purfuance of writs iffued in the name of the keepers of the liberty of England by authority of par¬ liament; and that the faid parliament fat till the 29th of December, full feven months after the Reftpration ; and enafted many laws, feveral of which are ftill in force. But this was for the neceffity of the thing, which fuperfedes all law; for if they had not fo met, it was morally impoffible that the kingdom ftiould havp been fettled in peace. And the firft thing done after the king’s return was, to pafs an aft declaring this to be a good parliament, notwithftanding the defeft of the king’s writs. So that as the royal prerogative was chiefly wounded by their fo meeting, and as the king himfelf, who alone had a right to objeft, confented to wave the objeftion, this cannot be drawn into an ex¬ ample in prejudice of the rights of the crown. Be- fides, we (hould alfo remember, that it was at that time a great doubt among the lawyers, whether even this healing aft made, it a good parliament, and held by very many in the negative ; though it feems ,to have been too nice a fcruple. And yet, out of abundant caution, it was thought neceffary to confirm its afts in the next parliament, by ftatute 13 Car. II. c. 7. &' c- H-. . - It is likewife true, at the time of the Revolution, A. D. 1688, the lords and commons by their own authority, and upon the fummons of the. prince, of Orange, (afterwards king William), met in a conven¬ tion, and therein difpofed of the crown and kingdom. But it muft be remembered, that this affembling was upon a like principle of neceffity as at the Reftoration; that is, upon a full conviftion that king James the fecond had abdicated the government, and that the throne was thereby vacant: which fuppofition of the individual members was confirmed by their concurrent refolution, when they aftually came together. And, in fuch a cafe as the palpable vacancy of a throne, it follows ex neceffitate ret, that the form of the royal writs mull be laid afide, otherwife no.parliament can ever meet again. For let us put another poffible cafe, and fuppofe, for the Jake of argument, that the whole PAR Parliament, whole royal line ftiould at any time fail, and become extinft, which would indifputably vacate the throne: in this fituation it feems reafonable to prefume, that the body of the nation, confiding of lords and com¬ mons, would have a right to meet and fettle the go¬ vernment ; otherwife there mud be no government at all. And ilpon this and no other principle did the convention in 1688 affemble. The vacancy of the throne was precedent to their meeting without any royal fummons, not a confequence of it. They did not affemble without writ, and then make the throne vacant; but, the throne being previoufly vacant by the king’s abdication, they afiembled without writ, as they mud do if they aflembled at all. Had the throne been full, their meeting would not have been regular ; but, as it was really empty, fuch mealing became abfolutely neceffary. And accordingly it is declared by datute 1 W. & M. d. 1. c. 1. that this convention was really the two houfes of parliament, notwithdanding the want of writs or other defers of form. So that, notwithdanding thefe two capital ex¬ ceptions, which were judifiable only on a principle of neceffity', (and each of which, by the way, induced a revolution in the government), the rule laid down is in general certain, that the king only can convoke a parliament. And this, by the ancient datutes of the realm, he is bound to do every year, or oftener, if need be. Not that he is, or ever was, obliged by thefe datutes to call a new parliament every year ; but only to permit a parliament to fit annually for the redrefs of grie¬ vances, and difpatch of bufinefs, if need be. Thefe lad words are fo loofe and vague, that fuch of our monarchs as were inclined to govern without parlia¬ ments, negle&ed the convoking them, fometimes for a very confiderable period, under pretence that there was no need of them. But, to remedy this, by the datute 16 Car. II. c. 1. it is enadled, that the fitting and holding of parliaments fhall not be intermitted above three years at the mod. And by the datote 1. W. & M. d. 2. c. 2. it is declared to be one of the rights of the people, that for redrefs of all grievances, and for the amending, drengthening, and preferving the laws, parliaments ought to be held frequently. And this indefinite frequency is again reduced to a certainty by datute 6 W. & M. c. 2. which enafts, as the datute of Charles the fecond had done before, that a new parliament fhall be called within three years after the determination of the former. II. The conJUtuent farts of a parliament are, the king’s majedy, fitting there in his royal political capacity, and the three edates of the realm ; the lords fpiritual, the lords temporal, (who fit together whh the king in one houfe), and the commons, who fit by themfelves in another. And the king and thefe three edates together form the great corporation or body politic of the kingdom, of which the king is faid to be caput, principium, et finis. For upon their coming together the king meets them, either in perfon or by reprefentation ; without which there can be no beginning of a parliament; and he alfo has alone the power of diffolving them. It is highly neceffary for preferving the balance of the conditution, that the executive power fhould be a branch, thoug not the whole, of the legiflature. The PAR total union of them, we have feen, would be produc-Parliament, live of tyranny; the total disjunftion of them, for the'- prefent, would in the end produce the fame effefts, by caufing that union againd which it feems to pro¬ vide. The legiflature would foon become tyrannical, by making continual encroachments, and gradually afluming to itftlf the rights of the executive power. Thus the long parliament of Charles the firfi, while it aftcd in a conftitutional manner, with the royal con¬ currence, redreffed many heavy grievances and edablilh- ed many falutary laws. But when the two houfes affumed the power of legiflation, in exclufion of the royal authority,they foon afteraffumed likewifethe reins of adminidration ; and, in confequence of thefe united powers, overturned both church and date, and eda- blidied a worfe oppreflion than any they pretended to remedy. To hinder therefore any fuch encroachments, the king is himfelf a part of the parliament; and as this is the reafon of his being fo, very properly there¬ fore the fhare of legiflation which the conditution has placed in the crown, confids in the power of re- je&ing, rather than refolving; this being fufficient to anfwer the end propofed. For we may apply to the royal negative, in this indance, what Cicero obferves of the negative of the Roman tribunes, that the crown has not any power of doing wrong, but merely of preventing wrong from being done. The crown can¬ not begin of itfelf any alterations in the prefent eda- blifhed law ; but it may approve or difapprove of the alterations fuggeded and confented to by the two houfes. The legiflature therefore cannot abridge the executive power of any rights which it now has by law, without its own confent; fince the law mud per¬ petually dand as it now does, unlefs all the powers will agree to alter it. And herein indeed confids the true excellence of the Britifh government, that all the parts of it form a mutual check upon each other. In the legiflature, the people are a check Upon the no¬ bility, and the nobility a check upon the people, by the mutual privilege of rejedling what the other has refolved ; while the king is a check upon both, which preferves the executive power from encroachments. And this very executive power is again checked and kept within due bounds by the two houfes, through the privilege they have of inquiring into, impeaching, and punifhing the condu£t (not indeed of the king, which would dedroy his conditutional independence ; but, which is more beneficial to the public) of his evil and pernicious counfellors. Thus every branch of our civil polity fupports and is fupported, regulates and is regulated, by the red : for the two houfes na¬ turally drawing in .two diredlions of oppofite intered, and the prerogative in another dill different from them both, they mutually keep each other from exceeding their proper limits; while the whole is prevented from feparation, and artificially conne&ed together by the mixed nature of the crowm, which is a part of the le- giflative, and the foie executive magiilrate. Like three didindt powers in mechanics, they jointly impel the machine of government in a diredtion different from what cither, adling by itfelf, would have done; but at the fame time in a direftion partaking of each, and formed out of all; a diredlion which conditutes the true line of the liberty and happinefs of the com¬ munity. 33 D 2 Having t 5873 1 PAR [ 5874 ] PAR Parliament. Having already confidered thefe condiment parts of the fovereign power, or parliament, each in a feparaie view, under the articles King, Lords, and Commons, to which the reader is referred, we proceed, III. To examine the laws and cuftoms relating to parliament, united together and conftdered as one aggre¬ gate body. The power and jurifdiclion. of parliament, fays Sir Edward Coke, isfo tranfcendent and abfolute, that it cannot be confined, either for caufes or perfons, within any bounds. And of this high court he adds, it may be truly faid, Si antiquitatem fpettes, eji vetu- flifjima ; fi dignitatem, eji honor at iflima ; Ji jurifdiSim- nem, eft. capacijfttna. It hath fovereign and uncon- trolable authority in making, confirming, enlarging, reftraining, abrogating, repealing, reviving, and ex¬ pounding of laws, concerning matters of all poffible denominations, ecclefiaftical or temporal, civil, mi¬ litary, maritime, or criminal: this being the place where that abfolute defpotic power, which mull in all governments refide fomewhere, is entrufted by thecon- ilitution of thefe kingdoms. All mifehiefs and grie¬ vances, operations and remedies, that tranfcend the ordinary courfe of the laws, are within, the reach of this extraordinary tribunal. It can regulate or new- model the fucceffion to the crown; as was done in the reign of H,enry VIII. and William III. It can alter the eftablilhed religion of the land ; as was done in a variety of inltances, in the reigns of king Henry VIII. and his three children. It can change and create afrefh even the conftitution of the kingdom and of parliaments themfelves; as was done: by the aft of union, and the feveral ftatutes for triennial and fepten- nial ele&ions. It can, in (hart, do every thing that is not naturally impoffible ; and therefore fome have not fcrupled to call its power, by a figure rather too bold, the omnipotence of parliament. True it is,, that what the parliament doth, no authority upon earth can undo. So that it is a matter moft efiential to the liberties of this kingdom, that fuch members be dele¬ gated to this important trull as are moft eminent for their probity, their fortitude, and their knowledge ; for it was a known apothegm of the great lord trea- furer Burleigh, “ That England could never be ruined but by a parliamentand, as Sir Matthew Hale ob- ferves, this being the higheft and greatell court, over which none other can have jurifdidlion in the king¬ dom, if by any means a mifgovernment Ihould any way fall upon it, the fubjeCls of this kingdom are left without all manner of remedy- To the fame pur- pofe the prefident Montefquieu, though we truft too haftily, prefages, that as Rome, Sparta, and Car¬ thage, have loft their liberty and perilhed ; fo the con- llitution of England will in time lofe its liberty, will perilh: it will pcrilh whenever the legiflativc power (hall become more corrupt than the executive. It mull be owned that Mr Locke, and other theo¬ retical writers, have held, that “ there remains ftill in¬ herent in the people a fupreme power to remove or al¬ ter the legiflative, when they find the legiflative adl contrary to the truft repofed in them ; for when fuch truft is abufed, it is thereby forfeited, and devolves to thofe who gave it." But however juft this conclu* fion may be in theory, we cannot adopt it, nor argue from it, under any difpenfation of government at pre- £ent aftually exifting. For this devolution of power, to the people at large, includes in it a diflblu.:Lcm of Parliamsnt. the whole form of government eftablilhed by that pea- ’ pie ; reduces all the members to their original (late of equality ; and by annihilating the fovereign power, re¬ peals all politive laws whatfuever before enabled. No human laws will therefore fuppofe a cafe, which at once mull deftroy all law, and compel men to build a- frefh upon a new foundation j nor will they make pro- vifion for fo defperate an event, as mull render all le¬ gal provrfions iueffcdlual. So long therefore as the Englilh conftitution lafts, We may venture to affirm, that the power of parliament is abfolute and without control. In order to prevent the mifehiefs that might arife, by placing this extenfive authority in bands that are either incapable or elfe improper to manage it, it is provided by the cuftam and law of parliament, that no one fhall fit or vote in either houfe, unlefa he be 21 years of age. This is alfo exprefsly declared by llatute 7 & 8 W. III. c. 25 : with regard to the houfe of commons, doubts have arifen, from fome contra- didory adjudications, whether or no a minor was in¬ capacitated from fitting in that houfe. It is alfo en¬ abled by ftatute 7 Jac. I. c. 6. that no member be permitted to enter the houfe of commons till he hath taken the oath of allegiance before the lord fteward or his depnty: and by 30 Car. II. ft. 2. and 1 Geo. I. c. 13. that no member (hall vote or fit in either houfe till he hath, in the prefence of the houfe, taken the oaths of allegiance, fupremacy, and abjuration, and fubferibed and repeated the declaration againA tran- fubftantiation, and invocation of faints, and the facri- fice of the mafs. Aliens, unlefs naturalized, werelike- wife by the law of parliament incapable to ferve there¬ in : and nowit is ena&ed, by ftatute 12 & t3 W. III. c. 2. that no alien, even though he be naturalized, (hall be capable of being a member of either houfe of parliament. And there are not only thefe Handing incapacities ; but if any perfon is made a peer by the king, or ele&ed to ferve in the houfe of commons by the people, yet may the refpedive honfes, upon com¬ plaint of any crime in fuch perfon, and proof thereof, adjudge him difabled and incapable to fit as a mem¬ ber: and this by the law and cuftom of parliament. For as every court ofjuftice hath laws and euftoras for its diretSlion, fome the civil and canon, fome the common law, others their own peculiar laws and cu- ftoms; fa the high court of parliament hath alfo its own peculiar law, called the lex et confuetudo parlia- menti; a law which Sir Edward Coke obferves is ab omnibuj quxrenda, a multis ignorata, a panels cognita. It will not therefore be exptded that we (hould enter into the examination of this law with any degree of minutenefs ; fince, as the fame learned author allures us, it is much better to be learned out of the rolls of parliament and other records, and by precedents and continual experience, than can he expreffed by any one man- It will be fufficient to obferve, that the whole of the law and cuflom of parliament has its ori¬ ginal from this one maxim, “ That whatever matter arifes concerning either houle of parliament, ought to be examined, difenffed, and adjudged in that houfe to ' which it relates, and not elfewhere." Hence, for in- ftance, the lords will not fuffer the commons to inter¬ fere: in fettling the eledion of a peer of Scotland ; the commons PAR [ 5875 ] PAR Parliament, commons will not allow the lords to judge of the elec- ‘ tion of a hurgefs; nor will either houfe permit the fubordinate courts of law to examine the merits of ei¬ ther cafe. But the maxims upon which they proceed, together with the method of proceeding, red entirely in the bread of the parliament itfelf; and are not de¬ fined and afcertained by any particular dated laws. The privileges of parliament are likewife very large and indefinite ; and therefore, when, in 31ft Hen. VI. the houfe of lords propounded a queftion to the judges concerning them, the chief judice, Sir John Fortef- cue, in the name of Iris brethren, declared, “ That they ought not to make anfwer to that quedion; for it hath not been ufed aforetime, that the judices Ihotild in any wife determine the privileges of the high court of parliament; for it is fo high and mighty in its na¬ ture, that it may make law; and that which is law, it may make no law : and the determination and know¬ ledge of that privilege belongs to the lords of parlia¬ ment, and not to the judices.” Privilege of parlia¬ ment was principally edablifhed, in order to proteft its members not only from being moleded by their fel- low-fubjedts, but alfo more efpecially from being op- prefied by the power of the crown. If therefore all the privileges of parliament were once to be fet down and afcertained, and no privilege to be allowed but what was fo defined and determined, it were eafy for the executive power to devife fome new cafe, not with¬ in the line of privilege, and under pretence thereof to harrafs any refraflory member, and violate the free¬ dom of parliament. The dignity and independence of the two houfes are therefore in great meafure pre- ferved by keeping their privileges indefinite. Some* however, of the more notorious privileges of the mem¬ bers of either houfe, are privilege of fpeech, of perfon, of their domedics, and of their lands and goods. As to the fird, privilege of fpeech, it is declared by the ftatute x W. Sc M. ft. 2. c. 2. as one of tb? liberties of the people, “ That the freedom of fpeech, and de¬ bates, and proceedings in parliament, ought not to be impeached or quedioned in any court or place out of parliament.” And this freedom of fpeech is particu¬ larly demanded of the king in perfon, by the fpeaker of the houfe of commons, at the opening of every new parliament. So likewife are the other privileges, of perfon, fervants, lands, and goods ; which are im¬ munities as ancient as Edward the Confefibr s in whofe laws we find this precept, fynodos venier.tibus, five fummoniti fnt, five per fe quid agendum habuerint fit fumma pax; and fo too in the old Gothic conflitu- tions, Extenditur hac pax et fecuritas ad quatuordecim dies, convocato regni fenatu. This included formerly not only privilege from illegal violence, but alfo from legal arreds and feizures by procefs front the courts of law. And ftill to afiault by violence a member of ei¬ ther houfe, or his menial fervants, is a high contempt of parliament, and there punidied with the utmod fe- verity. It has likewife peculiar penalties annexed to it in the courts of law by the datutes 5 Hen. IV. c. 6. and 11 Hen. VI. c. ri. Neither can any member of either houfe be arreded and taken into cudody with¬ out a breach of the privilege of parliament. But all other privileges which derogate from the common law are now at an end, fave only as to the freedom of the member’s perfon ; which in a peer (by the privilege of peerage) is for ever facred and invio-Parl'3mcnt* lable ; and in a commoner (by the privilege of pariia- meat) for forty days after every prorogatiou, and forty days before the next appointed meeting ; which is now in effect as long as the parliament fubfids, it feldom being prorogued for more than eighty days at a time. As to all other privileges which obltrmfr the ordinary courfe of judice, they were redrained by the datutes 12 W. III. c. 3. 2 & 3 Ann. c. 18. and 11 Geo. I t. c. 24. and are now totally abolilhed by datute 10 G. III. c. 50. ; which enads, that any fuit may at any time be brought agaioft any peer or member of par¬ liament, their fervants, or any other perfon entitled to privilege of parliament ; which (hall not be impeached or delayed by pretence of any fuch privilege, except that the perfon of a member of the houfe of commons fhall not thereby be fubjedted to any arred or impri- fonment. Likewife, for the benefit of commerce, it is provided by datute 4 Geo. III. c. 33. that any tra¬ der, having privilege of parliament, may be ferved with legal procefs for any jud debt, (to the amount of 100I.)} and unlefs he makes fatisfadion within two months, it (hall be deemed an ad of bankruptcy ; and that com- miffions of bankrupt may be iflued againd fuch privi¬ leged traders in like manner as againd any other. The only way by which courts of juftice could an¬ ciently take cognizance of privilege of parliament was by writ of privilege, in the nature of a fuperfedeas, to deliver the party out of cudody when arreded in a ci¬ vil fuit. For when a letter was written by the fpeaker to the judges, to day proceedings againd a privileged perfon, they rejeded it as contrary to their oath of of¬ fice. But fince the datute 12 Will. III. c. 3. which enads, that no privileged perfon (hall be fubjed to ar¬ red or imprifonment, it hath been held, that fuch arreft i; irregular ah initio, and that the party may be dif- charged upon motion. It is to be obferved, that there is no precedent of any fuch writ of privilege, but only in civil fuits; and that the datute of 1 Jac. I. c. 13. and that of king William, (which remedy fome inconvtni- encies arifing from privilege of parliament), fpeak only of civil adions. And therefore the claim of privilege hath been ufually guarded with an exception as to the cafe of indidable crimes; or, as it hath been frequent¬ ly expreffed, of treafon, felony, and breach (or furety) of the peace. Whereby it feems to have been under- ftood, that no privilege was allowable to the members, their families, or fervants, in any crime whatfoever; for all crimes are treated by the law as being contra pacem domini reg'is. And indances have not been wanting, wherein privileged perfons have been convidcd of mif- demefnors, and committed, or profecuted to outlawry,, even in the middle of a ftfiion; which proceeding has afterwards received the fandion and approbation o£ parliament. To which may be added, that a few years ago, the cafe of writing and publifhing feditious libels was refolved by both houfes not to be entitled to pri¬ vilege; and that the reafons upon which that cafe pro¬ ceeded, extended equally to every indidable offence. So that the chief, if not the only, privilege of parlia¬ ment, in fuch cafes, feems to be the right of receiving" immediate information of the imprifonment or deten¬ tion of any member, with the reafon for which he is. detained : a pradicethat is daily ufed upon the flight- eft military aecufations, preparatory to a trial by a. cx>urfc PAR [ 5876 ] PAR Patl'ament. court-martial; and which is recognized by the feveral temporary ftatutes for fufpending the habeas corpus aft: whereby it is provided, that no member of either houfe fhall be detained, till the matter of which he (lands fuf- pefted be firft communicated to the houfe of which he is a member, and the confent of the fa id houfe ob¬ tained for his commitment or detaining. But yet the ufage has uniformly been, ever fince the Revolution, that the communication has been fubfequent to the ar- reft. Thefe are the general heads of the laws and cuftoms relating to parliament, confidered as one aggregate body. The laws and cuftoms relating to each branch in particular being explained under the articles already referred to, viz. King,Lords,andCoMMONS,we(hould proceed, IV. To the method of making laws; which is much the fame in both houfes. But for this, too, we have to refer the reader to the article Bill; and (hall only obferve in this place, that, for difpatch ofbufinefs, each houfe of parliament has its fpeaker. The fpeaker of the houfe of lords, whole office it is to prefide there, and manage the formality of bufmefs, is the lord chan¬ cellor, or keeper of the king’s great feal, or any other appointed by the king’s commiffion: and if hone be fo appointed, the houfe of lords (it is faid) may eleft. The fpeaker of the houfe of commons is chofen by the houfe; but mu ft be approved by the king. And here¬ in the ufage of the two houfes differs, that the fpeaker of the houfe of commons cannot give his opinion or argue any queftion in the houfe ; but the fpeaker of the houfe of lords, if a lord of parliament, may. In each houfe the aft of the majority binds the whole; and this majority is declared by votes openly and pub¬ licly given ; not, as at Venice, and many other fenato- rial affemblies, privately, or by ballot. This latter me¬ thod may be ferviceable, to prevent intrigues and un- eonftitutional combinations; but is impofllble to be praftifed with us, at lead in the houfe of commons, where every member’s'conduft is fubjeft to the future cenfure of his conftituents, and therefore flrould be o- penly fubmitted to their infpeftion. V. There remains only, in the laft place, to add a word or two concerning the manner in which parlia¬ ments may be adjourned, prorogued, or dijfolved. An adjournment is no more than a continuance of the feffion from one day to another; as the word itfelf Cgnifies: and this is done by the authority of each houfe feparately every day; and fometimes for a fort¬ night or a month together, as at Chriftmas or Eafter, or upon other particular occafions. But the adjourn¬ ment of one houfe is no adjournment of the other. It hath alfo been ufual, when his Majefty hath fignified his pleafure that both or either of the houfes ffiould adjourn themfelves to a certain day, to obey the king’s pleafure fo Qgnified, and to adjourn accordingly. O- therwife, befides the indecorum of a refufal, a proro¬ gation would affuredly follow; which would often be very inconvenient to both public and private bufinefs. For prorogation puts an end to the fedion ; and then fuch bills as are only begun and not perfefted, muff; be refumed de novo, (if at all), in a fubfequent fefiion ; whereas, after an adjournment, all things continue in the fame Rate as at the time of the adjournment made, and may be proceeded on without any freffi commence¬ ment. ' A prorogatiosth the continuance of the parliament Parliament. from one feffion to another ; as an adjournment is a continuation of the feffion from day to day. This is done by the royal authority, expreffed either by the lord chancellor in his Majefty’s prefence, or by commiffion from the crown, or frequently by proclamation. Both houfes are neceffarily prorogued at the fame time; it not being a prorogation of the houfe of lords or com¬ mons, but of the parliament. The feffion is never un- derftood to be at an end until a prorogation; though, unlefs fome aft be paffed, or fome judgment given in parliament, it is in truth no feffion at all. And former¬ ly the ufage was, for the king to give the royal aflent to all fuch bills as he approved at the end of every fef¬ fion, and then to prorogue the parliament, though fometimes only for a day or two; after which all buli- nefs then depending in the houfes was to be begun a- gain. Which cuftom obtained fo ftrongly, that it once became a queftion, Whether giving the royal aflent to a Angle bill did not of courfe put an end to the feffion ? And though it was then refolved in the negative, yet the notion was £0 deeply rooted, that the ftatute 1 Car. I. c. 7. was pafled to declare, that the king’s aflVnt to that and fome other afts ftrould not put an end to the feffion ; and even fo late as the reign of Charles II. we And a provifo frequently tacked to a bill, that his Majefty’s aflent thereto (hould not determine the feffion of parliament. But it now feems to be al¬ lowed, that a prorogation muft be exprefsly made, in order to determine the feffion. And if at the time of an aftual rebellion, or imminent danger of invaflon, the parliament (hall be feparated by adjournment or prorogation, the king is empowered to call them toge¬ ther by proclamation, with 14 days notice of the time appointed for their reaffembling. A dijfolution is the civil death of the parliament; and this may be effefted three ways: 1. By the king’s will, exprefled ■•ither in perfon or by reprefentation. For as the king has the foie right of convening the parlia¬ ment, fo alfo it is a branch of the royal prerogative, that he may (whenever he pleafes) prorogue the par¬ liament for a time, or put a Anal period to its exift- ence. If nothing had a right to prorogue or diflblve a parliament but itfelf, it might happen to become per¬ petual. And this would be extremely dangerous, if at any time it (hould attempt to encroach upon the ex¬ ecutive power; as was fatally experienced by the un¬ fortunate king Charles I.; who, having unadvifedly paffed an aft to continue the parliament then in being till fuch time as it (hould pleafeto diflblve itfelf, at laft; fell a facrifice to that inordinate power which he him- felf had confented to give them. It is therefore ex¬ tremely neceflary that the crown (hould be empowered to regulate the duration of thefe aflemblies, under the limitations which the Englifti conftitution has prefcri- bed: fo that, on the one hand, they may frequently and regularly come together for the difpatch of bufi¬ nefs and redrefs of grievances; and may not, on the other, even with the confent of the crown, be continued to an inconvenient or unconftitutional length. 2. A parliament may be difiblved by the demife of the crown. This diflblution formerly happened im¬ mediately upon the death of the reigning fovereign: for he being confidered in law as the head of the par¬ liament, (caput, principium, et finis), that failing, the whole PAR [ 5877 ] PAR Parliament, whole body was held to be extin&. But the calling a new parliament immediately on the inauguration of the fuccefibr being found inconvenient, and dangers being apprehended from haring no parliament in being in cafe of a difputed fucceffion, it was ena&ed by the fta- tutes 7 & 8 W. III. c. 15. and 6 Ann. c. 7. that the parliament in being ihall continue for fix months after the death of any king or queen, unlefs fooner prorogued or diifolved by the fucceffor: that if the parliament be, at the time of the king’s death, feparated by adjourn¬ ment or prorogation, it (hall notwithftanding affemble immediately: and that if no parliament is then in be¬ ing, the members of the laft parliament (hall affemble, and be again a parliament. 3. Laftly, a parliament may be diflblved or expire by length of time. For if either the legiflative body were perpetual, or might laft for the life of the prince who convened them as formerly, and were fo to be fupplied, by cccafionally filling the vacancies with new reprefentatives; in thefe cafes, if it were once corrup¬ ted, the evil would be paft all remedy; but when dif¬ ferent bodies fucceed each other, if the people fee caufe to difapprove of the prefent, they may rectify its faults in the next. A legiflative aflembly alfo, which is fure to be feparated again, (whereby its members will them- felves become private men, and fubjeft to the full ex¬ tent of the laws which they have enabled for others), will think themfelves bound, in intereft as well as duty, to make only fuch laws as are good. The utmoft ex¬ tent of time that the fame parliament was allowed to fit, by the ftatute 6 W. & M. c. 3. was three years ; after the expiration of which, reckoning from the re¬ turn of the firft fummons, the parliament was to have no longer continuance. But by the ftatute x Geo. I. ft. 2. c. 38. (in order, profefledly, to prevent the great and continued expences of frequent eledfions, and the violent heats and animofides confequent thereupon, and for the peace and fecurity of the government then juft recovering from the late rebellion), this term was pro¬ longed to /even years ; and, what alone is an inftance of the vaft authority of parliament, the very fame houfe that was chofen for three years, enatfted its own con¬ tinuance for ftven. So that, as our conftitution now ftands, the parliament muft expire, or die a natural death, at the end of every feventh year, if not fooner diflblved by the royal prerogative. We fhall conclude this anicle with an account of fome general forms not taken notice of under any of the above heads. In the houfe of lords, the princes of the blood fit by themfelves on the fides of the throne ; at the wall, on the king’s right hand, the two, archbilhops fit by themfelves on a form. Below them, the biftiops of London, Durham, and Winchefter, and all the other bifhops, fit according to the priority of their confecra- tion. On the king’s left hand the lord-treafurer, lord prefident, and lord privy-feal, fit upon forms above all dukes, except the royal blood ; then the dukes, mar- quiffes, and earls, according to their creation. A- crofs the room are wool-facks, continued from an an¬ cient cuftom ; and the chancellor, or keeper, being of courfe the fpeaker of the houfe of lords, fits on the firft wool-fack before the throne, with the great feal or mace lying by him ; below thefe are forms for the vifcounts and barons. On the other wool Lacks are feated the judges, matters in chancery, and king’s Parliament, council, who are only to give their advice in points of * ' law: but they all ftand up till the king gives them leave to fit. The commons fit promifcuoufly ; only the fpeaker has a chair at the upper end of the houfe, and the clerk and his afiiftant fit at a table near him. When a member of the houfe of commons fpeaks, he ftands up uncovered, and diredls his fpeech to the fpeaker only. If what he fays be anfwered by ano¬ ther, he is not allowed to reply the fame day, unlefs perfonal reflexions have been caft upon him: but when the commons, in order to have a greater freedom of debate, have refoived themfelves into a committee of the whole haufe, every member may fpeak to a que- ftion as often as he thinks neceflary. In the houfe of lords they vote, beginning at the puifne, or lowed: baron, and fo up orderly to the higdieft, every one an- fwering, Content or Not content. In the houfe of com¬ mons they vote by yeas and nays ; and if it be dubfous which are the greater number, the houfe divides. If the queftion be about bringing any thing into the houfe, the yeas go out; but if it be about any thing the houfe already has, the nays go out. In all divilions the fpeak¬ er appoints four tellers, two of each opinion. In a committee of the whole houfe, they divide by changing fides, the taking the right and the nays the left of the chair; and then there are but two tellers. If a bill pafs one houfe, and the other demur to it, a con¬ ference is demanded in the paintfed chamber, where certain members are deputed from each houfe ; and here the lords fit covered, and the commons ftand bare, and debate the cafe. If they difagree, the affair is null; but if they agree, this, with the other bills that have paffed both houfes, is brought down to the king in the houfe of lords, who comes thither clothed in his roy¬ al robes; before him the clerk of the parliament reads the title of each bill, and as he reads, the clerk of the crown pronounces the royal affentor diffent. If it be a public bill, the royal affent is given in thefe words, Leroy le vaut, “ The king will have it fo;” if private, Soi fait conime il eft defre, “ Let the requeft be com¬ plied with: if the king refufes the bill, the anfwer is, Le roy s’avifera, “ The king will think of it;” and if it be a money-bill, the anfwer is, Le roy rgmercie fes loyaux fujets, accepte leur benevolence, icf auffi le veut 1 “ The king thanks his loyal fubjeXs, accepts their benevolence, and therefore grants his confent.” High Court of Parliament, is the fupreme court in the kingdom, not only for the making, but alfo for the execution, of laws ; by the trial of great and enor¬ mous offenders, whether lords or commoners, in the method- of parliamentary impeachment. As for aXs of parliament to attaint particular perfons of treafon or felony, or to infliX pains and penalties, beyond or contrary to the common law, to ferve a fpecial pur- pofe, we fpeak not of them ; being to all intents and purpofes new laws, made pro re nata, and by no means an execution of fuch as are already in being. But an impeachment before the lords by the commons of Great Britain, in parliament, is a profecution of the already known and eftabliftied law, and has been frequently put in prdXice ; being a prefirntment to the moft high and fupreme court of criminal jurifdiXion by the moft folemn grand inqueft of the whole king¬ dom. PAR [ 58 parliament, dom. A commohet cannot, however, be Impeached ~ before the lords for any capital offence, but only for high mifdemefnors ; a peer may be impeached for any crime. And they ufually (in cafe of an impeachment of a peer for treafon) addrefs the crown to appoint a lord high fteward, for the greater dignity and re¬ gularity of their proceedings; which high fteward was formerly eleded by the peers themfelves, though he was generally commiffioned by the king; but it hath of late years been ftrenuoufly maintained, that the appointment of an high fteward in fuch cafes is not indifpenfably neceffary, but that the houfe may proceed without one. The articles of impeachment are a kind of bills of indi&ment, found by the houfe of commons, and afterwards tried by the lords; who are in cafes of mifdemefnors confidered not only as their own peers, but as the peers of the whole nation. This is a cuftom derived to us from the conftitntion of the ancient Germans; who in their great councils fome- times tried capital accufations relating to the public : Licet apud concilium accufare quoque, et difcrimen capitis intendere. And it has a peculiar propriety in the Englifh conftitution ; which has much improved upon the ancient model imported hither from the continent. For though in general the union of the legiflative and judicial powers ought to be moft carefully avoided, yet it may happen that a fubjed, intrufted with the adminiftration of public affairs, may infringe the rights of the people, and be guilty of fuch crimes as the ordinary magiftrate cither dares not or cannot punifh. Of thefe the reprefentatives of the people, or houfe of commons, cannot properly judge ; becaufe their con- ftituents are the parties injured, and can therefore only impeach. But before what court {hall this im¬ peachment be tried ? Not before the ordinary tri¬ bunals, which would naturally be fwayed by the au¬ thority of fo powerful an accufer. Reafon therefore will fuggeft, that this branch of the legiflature, which reprefents the people, muft bring its charge before the other branch, wdiich confifts of the nobility, who have neither the fame interells, nor the fame paffions,~as popular aflemblies. This is a vaft fuperiority which the conftitution of this ifland enjoys over thofe of the Grecian or Roman republics; where the people were at the fame time both judges and accufers. It is pro¬ per that the nobility {hould judge, to infure juftice to the accufed ; as it is proper that the people fhould accufe, to infure juftice to the commonwealth. And therefore, among other extraordinary circumflances attending the authority of this court, there is one of a very lingular nature, which was infilled on by the houfe of commons in the cafe of the earl of Danby in the reign of Charles H. and is now enaded by ftatute 12 & 13 W. III. c. 2. that no pardon under the great feal {hall be pleadable to an impeachment by the commons of Great Britain in parliament. Parliaments of France, are fovereign courts efta- blilhed by the king, finally to determine all difputes between particular perfons, and to pronounce on ap¬ peals from fentences given by inferior judges. There are ten of thefe parliaments in France, of which that of Paris is the chief, its privileges and jurifdidion be¬ ing of the greateft extent. It confifts of fix chambers, v z. the grand chamber, where caufes of audiences are pleaded ; and five chambers of inqueft, where proctfies 78 ] PAR are adjudged in writing. This parliament enjoys theP*iliament. privileges of verifying and regiftering the king’s arrets 1 . or edids, without which thofe edids are of little or armeSia^ no value. Parliament of Sweden, confifts of four eftates, with the king at their head : Thefe eftates are, x. The nobility and reprefentatives of the gentry ; with whom the colonels, lieutenant-colonels, majors, and captains of every regiment, fit and vote. 2. The clergy j one of which body is eleded from every rural deanry of ten parifhes; who, with the bifhops and fuperintendents, amount to about two hundred. 3. The burghers, eleded by the magiftrates and council of every cor¬ poration as their reprefentatives, of whom their are four for Stockholm, and two for every other town, amounting in the whole to about an hundred and fifty. 4. The peafants, chofen by tbe peafants out of every diftrid ; who choofe one of their own rank, and not a gentleman, to reprefent them: thefe amount to about two hundred and fifty. All thefe generally meet at Stockholm : and after the ftate-affairs have been reprefented to them from the throne, they feparate, and fit in four feveral cham¬ bers or houfes, in each of which affairs are carried on by majority of votes; and every chamber has a nega¬ tive in tbe paffing any law. PARMA, an ancient, rich, populous, and hand- fome town of Italy", capital of the duchy of the fame name, with a citadel, a biftiop’s fee, and an univer- fity. it has a magnificent cathedral, and the largeft opera-houfe in Europe, which has feats for 8000 people; but as it required a vaft number of candles, which occafioned great expence, they have contrived another which h4s room for 2000 fpedators. The dome and the chureh of St John are painted by the famous Corregio, who was a native of this place. Don Carlos, king of the two Sicilies, carried away the library to Naples, which contained 18,000 volumes, and a very valuable cabinet of euriofities, as alfo the rich colleftion of medals. The citadel, which is very near the city, is built in the fame tafte as that at Antwerp. In 1734 there was a bloody battle fought here; and in 1741, by the treaty of Aix-la-Chapelle, the duchies of Parma, Placvntia, and Gnaftalla, were given to Don Philip, brother to Don Carlos above- mentioned.

The air is very wholefome, on which account the inhabitants live to a great age. The foil is very fertile in corn, wine, oil, and hemp ; the paftures feed a great number of cattle, and the cheefe was in very high efteetn. Here are confiderable mines of copper and filver, and plenty of truffles, which many are very fond of. PARMEGIANO, a celebrated painter, whofetrue name was Francefco Mazzuoli ; but he received the former from the city of Parma, where he was born, in 1504. He was brought up under his two uncles, and was an eminent painter when but fixteen years of age. He was famous all over Italy at nineteen ; and at Parnaffiis H 1‘aronoma- fia. PAR [ 5879 ] PAR at twenty-three performed fuch wonders, that when the general of the emperor Charles V. took Rome by ftorm, fome of the common foldiers having, in • facking the town, broke into his apartments, found him intent upon his work, and were inftantly fo ftruck with the beauty of his pieces, that inftead of involving him in the plunder and deftru&ion in which they were then employed, theyTefolved to proteft him from all manner of violence; which they aftually performed. His works are dittinguifhed by the beauty of the co¬ louring, the invention, and drawing. His figures are fpirited and graceful, particularly with refp.eift to the choice of attitude, and in their drefies. He alfo ex¬ celled in mufic, in wh' h he much delighted. His principal works are. at Parma, where he lived for fe- veral years in great reputation ; till unhappily he in¬ volved himfelf in ruin, by fpending a confiderable part of his time and fortune in fearch of the philofopher’s Hone; and died poor in-1540. There are extant many valuable prints made by this mailer, hot only in chiaro ofeuro, but alfo in etching with aqua-fortis, of which he is faid to be the inven¬ tor, or at leaftthe firft who pradlifed the art of etching in Italy. PARNASSIA, grafs of Parnaflus 5 a genus of the tetragynia order, belonging to the pentandria clafs of plants. There is but one fpecies, having a fialk about a foot high, angular, and often a little twifted, bearing a fingle white flower at top. The flowers are very beautifully ftreaked with yellow; fo that though it is a common plant, growing natu¬ rally in moift paftures, it is frequently admitted into gardens. PARNASSUS, (Strabo, Pindar, Virgil), a moun¬ tain of Phocis, near Delphi, and the mounts Cithfe- ron and Helicon, with two tops, (Ovid, Lucan); the one called Cirrha, facred to Apoilo; and the other, Ni/a, facred to Bacchus, (Juvenal). It was covered with bay trees, (Virgil) ; and originally called Lar- najfus, from Deucalion’s larnax or ark, thither con¬ veyed by the flood, (Stephanusr-Scboliaft on Apollo¬ nius); after the flood, Parnaffus; from Har Nahas, changing the h into p, the hill of divination or au¬ gury, Peucerus; the oracle of Delphi Handing at its foot. PARNELL (Dr Thomas), a very ingenious di¬ vine and poet in the early part of this century. He was archdeacon of Clogher, and the intimate friend of Mr Pope; who publifhed his works, with an elegant copy of recommendatory verfes prefixed. He died in 1718, aged 39. PARODY, a popular maxim, adage, or proverb. Parody, is alfo a poetical pleafantry, confiding in applying the verfes written on one fubjedt, by way of ridicule, to another ; or in turning a ferious work into a burlefque, by affe&ing to obferve as near as poffible the fame rhimes, words, and cadences. PAROLE, in a military fenfe, the promife made by a prifoner of war, when he has leave to go any where, of returning at a time appointed, if not ex¬ changed.

PAROXYSM, in medicine, the fevere fit of a difeafe, under which it grows higher or exafperated ; as of the gout, &c. PARR (Catharine), was the elded daughter of Sir Thomas Parr of Kendall. She was fird married to John Nevil, lord Latymer; after whofe death Ihe fo captivated her amorous fovereign, that he raifed her to the throne. The royal nuptials were folemnifed at Hampton Court on the 12th of July 1543. Being religioufly difpofed, (he was, in the early part of her life, a zealous obferver of the Romiflr rites and cere¬ monies ; but,' in the dawning of the Reformation, fhe became as zealous a promoter of the Lutheran doc¬ trine ; yet with fuch prudence and circumfpeftion as her perilous lituation required. Neverthelefs, we are told, that (he was in great danger of falling a facri- fice to the Popifh faction, the chief of whom was bi- ffiop Gardiner: he drew up articles againd her, and prevailed on the king to fign a warrant to remove her to the Tower. This warrant was, however, acciden- dentally dropped, and immediately conveyed to her majefty. What her apprehenfions mud have been on this occafion, may beeafily imagined. She knew the monarch, and die could not help recolleding the fate of his former queens. A fudden illnefs was the natu¬ ral confequence. The news of her indifpofition brought the king to her apartment. He was laviffi in expref- fions of affedtion, and fent her a phyfician. His ma- jedy being foon after alfo fomewhat indifpofed, (he prudently returned the vifit; with which the king feemed pleafed, and began to talk with her on reli¬ gious fubjedts, propofing certain queftions, concern¬ ing which he wanted her opinion. She anfwered, that fuch profound fpeculations were not fuited to her fex ; that it belonged to the hufband to choofe principles for his wife ; the wife’s duty was, in all cafes, to adopt implicitly the fentiments of her huf¬ band : and as to herfelf, it was* doubly her duty, be¬ ing bleffed with a htifband who was qualified, by his judgment and learning, not only to choofe princt- les for his own family, but for the mod wife and nowing of every nation. “ Not fo, by St Mary,” replied the king; “ you are now become a doctor, Kate, and better fitted to give than receive indruc- tion.” She meekly replied, that die was fenfible how little fhe was entitled to thefe praifes ; that though fhe ufually declined not any converfation, however fublime, when propofed by his Majedy, fhe well knew that her conceptions could ferve to no other purpofe than to give him a little momentary amufe- ment; that fhe found the convcrfatien a little apt to languifh when not revived by fome oppofuion, and 33 E fhe PAR [ 5880 ] PAR Parr /he had ventured fometimes to feign a contrariety of Par ^c de ^ent*ments» *n OTder to give him the pleafure of re- rri 1 futing her; and that flie-alfo propofed, by this inno¬ cent artifice, to engage him into topics whence fhe had obferved by frequent experience, that /he reaped profit and inftruftion. “ And is it fo, fweetheart ?” replied the king, “ then we are perfedt friends a- gain.” He embraced her with great affe&ion, and fent her away with aflurances of his prote&ion and kindnefs. The time being now come when /he was to be fent to the Tower, the king, walking in the garden, fent for'the queen, and met her with great good humour; when lo the chancellor, with forty of the guards, ap¬ proached. He fell upon hig knees, and /poke foftly with the king, who called him knave, arrant knave, bead, fool, and commanded him inftantly to depart. Henry then returned to the queen, who ventured to intercede for the chancellor : “Ah poorfould!” faid the king, “ thou little knoweft how evil he deferveth this grace at thy hands. Of my word, fweetheart, he hath been toward thee an arrant knave; and fo let him go.” The king died in January 1547, juft three years and a half after his marriage with this fecond Catharine; who in a fiiort time was again efpoufed to Sir Thomas Seymour lord-admiral of England; for, in September 1548, /he died in childbed. Thehifto- rians of this period generally infinuate, that /he was poifoned by her hufband, to make way for his mar¬ riage with the lady Elizabeth. That Catharine Parr was beautiful, is beyond a doubt: that /he was pious and learned, is evident from her waitings : and that her prudence and fagacity were not inferior to her other accompli/hments, may be concluded from her holding up the paflion of a capri¬ cious tyrant as a ftiield againft her enemies ; and that at the latter end of his days, when his paffions were enfeebled by age, and his peevi/h aufterity increafed by difeafe.

By the Roman law, it was puni/hed in a much feverer manner than any other kind of homicide. After being fcourged, the delinquents were fewed up in a leathern fack, with a live dog, a cock, a viper, and Parrot an ape, and fo call into the fea. Solon, it is true, !1 in his laws, made none againft parricide ; apprehend- arfon* ing it impoffible that one /hould be guilty of fo unna¬ tural a barbarity. And the Perfians, according to Herodotus, entertained the fame notion, when they adjudged all perfons who killed their reputed parents to be baftards.. And upon fome fuch reafon as this muft we account for the omiflion of an exemplary pu- ni/hment for this crime in our Englf/h laws; which treat it no otherwife than as fimple murder, unlefs the child was alfo the fervant of the parent. For though the breach of natural relation is unob- - ferved, yet the breach of civil or ecclefiaftic connec¬ tions, when coupled with murder, denominates it a new offence ; no lefs than a fpecies of treafon called parva proditio, or petit treafon: which, however, is nothing elfe but an aggravated degree of murder ; al¬ though, on account of the violation of private al¬ legiance, it is ftigmatized as an inferior fpecies of treafon. And thus, in the ancient Gothic conftitu- tion, we find the breach both of natural and civil re¬ lations ranked in the fame clafs with crimes againft the ftate and fovereign. PARROT, in ornithology.

A parfon, perfona eccle- ftrM/i«». were wont to depute one of their own body to per¬ form divine fervice, and adminifter the facraments, in thofe parifhes of which the fociety was thus the par¬ fon. This officiating minifter was in reality no more than a curate, deputy, or vicegerent of the appropri- ator, and therefore called vicarius, or “ vicar.” His ftipend was at the diferetion of the appropriator, who was, however, bound of common right to find fome- body, qui Hit de temporalibus, cpifcopo de fpiritualibus, debeat refpondere. But this was done in fo fcandalous a manner, and the pari/hes fuffered fo much by the negleft of the appropriators, that the legi/lature was forced to interpofe: and accordingly it is ena&ed, by ftatute 15 Ric. II. c. 6. that in all appropriations of churches PAR [ 5881 ] PAR P»rfon. churches the diocefan bifhop fhall ordain (In propor- ' tion to the value of the church) a competent fum to be dlftributed among the poor parlfhioners annually ; and that the vicarage fhall be fufficiently endowed. It feems the parifh were frequently fufferers, not only by the want of divine fervice, but alfo by with-holding thofe alms for which, among other purpofes, the pay¬ ment of tithes was originally impofed : and therefore in this aft a penfion is direfted to be diftributed among the poor parochians, as well as a fufficient ftipend to the vicar. But he, being liable to be removed at the pleafure of the appropriator, was not likely to infift too rigidly on the legal fufficiency of the ftipend ; and therefore, by ftatute 4 Hen. IV. c. 12. it Is ordain¬ ed, that the vicar fhall be a fecular perfon, not a mem¬ ber of any religious houfe ; that he fhall be vicar per¬ petual, not removable at the caprice of the mona- ftery ; and that he fhall be canonically inftituted and indufted, and be fufficiently endowed, at the difcre- tion of the ordinary ; for thefe three exprefs purpofes, to do divine fervice, to inform the people, and to keep hofpitality. The endowments, in confequence of thefe ftatutes, have ufually been by a portion of the glebe or land belonging to the parfonage, and a particular fhare of the tithes, which the appropriators found it inoft troublefome to colleft, and which are therefore .generally called privy, ox fmall tithes ; the greater, or predial tithes, being ftill referved to their own ufe. But one and the fame rule was not obferved in the en¬ dowment of all vicarages. Hence fome are more li¬ berally, and fome more fcantily, endowed : and hence the tithes of many things, as wood in particular, are in fome parifhes reftorial, and in fome vicarial tithes. The dittinftion therefore of a parfon and vicar is this: The parfon has for the moft part the whole right to all the ecclefiaflical dues in his parifh ; but a vicar has generally an appropriator over him, entitled to the beft part of the profits, to whom he is in effeft perpetual curate, with a {landing falary. Though in fome places the vicarage has been confiderably aug¬ mented by a large fhare of the great tithes; which augmentations were greatly afiifted by the ftatute 27 Car. II. c. 8. enafted in favour of poor vicars and curates, which rendered fuch temporary aug¬ mentations (when made by the appropriators) perpetual. The method of becoming a parfon or vicar is much the fame. To both there are four requifites necef- fary ; holy orders, prefentation, inftitution, and in- duftion. The method of conferring the holy orders of deacon and prieft, according to the liturgy and canons, is foreign to the prefent purpofe ; any farther than as they are neceffary requifites to make a complete par¬ fon or vicar. By common law, a deacon, of any age, might be inflituted and indufted to a parfonage or vi¬ carage: but it was ordained, by ftatute 13 Eliz. c. 12. that no perfon under twenty-three years of age, and in deacon’s orders, fhould be prefented to any benefice with cure ; and if he were not ordained prieft within one year after his induftion, he fhould be ipfo fatto deprived : and now, by ftatute 13 and 14 Car. II. c. 4. no perfon is capable to be admitted to any benefice, unlefs he hath been firft ordained a pried ; and then he is, in the language of the law, a clerk in orders. But if he obtains orders, or a licence to preach, by money or corrupt praftices, (which feems to be the true, though not the common, notion of fimony), the Parfo/r, perfon giving fuch orders forfeits 401. and the perfon receiving, 101. and is incapable of any ecclefiaftical preferment for feven years after. Any clerk may be prefented to a parfonage or vi¬ carage; that is, the patron, to whom the advowfon of the church belongs, may offer his clerk to the bi¬ fhop of the diocefe to be indituted. But when he is prefented, the bifhop may refufe him upon many ac¬ counts. As, 1. If the patron is excommunicated, and remains in contempt 40 days; or, 2. If the clerk be unfit: which unfitnefs is of feveral kinds. Firll, with regard to his perfon ; as if he be a badard, an outlaw, an excommunicate, an alien, under age, or the like. Next, with regard to his faith or morals f as for any particular herefy, or vice that is malum in fe; but if the bifhop alleges only in genera’s, as that he h fchifmaticus inveteratus, or objefts a fault that is malum prohibitum merely, as haunting taverns, playing at unlawful games, or the like, it is not good caufe of refufal. Or, ladly, the clerk may be undt to dif- charge the padoral office for want of learning. In any of which cafes, the bifhop may refufe the clerk. In cafe the refufal is for herefy, fcliifm, inability of learning, or other matter of ecclefiadical cognizance, there the bifhop mud give notice to the patron of fuch his caufe of refufal, who being ufually a layman, is not fuppofed to have knowledge of it; elfe he cannot prefent by lapfe* but if the caufe be temporal, there he is not bound to give notice. If an aftion at law be brought by the patron againft the bifhop for refufing his clerk, the bilhop mud affign the caufe. If the caufe be of a temporal nature, and the faft admitted, (as, for inftance, outlawry), the judges of the king’s courts mud determine its validity, or whether it be fufficient caufe of refufal: but if the faft be denied, it mad be determined by a jury. If the caufe be of a fpiritual nature, (as herefy, particu¬ larly alleged), the faft, if denied, fliall alfo be deter¬ mined by a jury : and if the faft be admitted or found, the court, upon confultation and advice of learned di¬ vines, fhall decide its fufficiency. If the canfe be want of learning, the bifhop need not fpecify in what points the clerk is deficient, but only allege that he is defi¬ cient; for the datute 9 Edw. II. U. 1. c. 13. is ex¬ prefs, that the examination of the fitnefs of a perfon prefented to a benefice belongs to the ecclefiaftical judge. But becaufe it would be nugatory in this cafe to demand the reafon of refufal from the ordinary, if the patron were bound to abide by his determination, who has already pronounced his clerk unfit ; therefore if the bifhop returns the clerk to be minus fufficiens in literatura, the court fhall write to the metropolitan to re-examine him, and certify his qualifications; whicli certificate of the archbifhop is final. If the bifhop hath no objeftions, but admits the pa¬ tron’s prefentation, the clerk fo admitted is next to be indituted by him ; which is a kind of invediture of the fpiritual part of the benefice ; for by inditution, the care of the fouls of the parifh is committed to the charge of the clerk. When a vicar is indituted, he (befides the ufual forms) takes, if required by the bilhop, an oath of perpetual refidence ; for the maxim of law is, that vicarius non habet vicariurn: and as the non-refi- dence of the appropriators was the caufe of the perpe- 33 E 2 tual PAR [ 5S82 ] PAR Pavfon. tual eftablifhment of vicarages, the law judges it very ' improper for them to defeat the end of their conftitu- tion, and'by abfence to create the very mifchiefwhich they were appointed to remedy ; efpecially as, if any profits are to arife from putting in a curate and living at a diftance from the parifh, the appropriator, who is the real parfon, has undoubtedly the elder title to them. When the ordinary is alfo the patron, and confers the living, the prefentation and inftitution are one and the fame ad, and are called a collation to a benefice. By inftitution or collation the church is full, fo that there can be no frefh prefentation till ano¬ ther vacancy, at leafl in the cafe of a common patron ; but the church is not full againft the king till induc¬ tion : nay, even if a clerk is inftituted upon the king’s prefentation, the crown may revoke it before induc¬ tion, and prefent another clerk. Upon inftitution alfo the clerk may enter on the parfonage-houfe and glebe, and take the tithes ; but he cannot grant or let them, or bring an aftion for them, till induclion. See In¬ duction. For the rights of a parfon or vicar, in his tithes and ecclefiaftical dues, fee Tithes. As to his duties, they are fo numerous, that it is impradicable to recite them here with any tolerable concifenefs or accuracy ; but the reader who has occafion may confult Bp Gib- fon’s Codex, and Burn's Ecclejiajlical Lam. We (hall therefore only juft mention the article of reiidence, up¬ on the fuppofition of which the law doth ftyle every parochial minifter an incumbent. Byftatuteat Hen. VIII. c. 13. perfons willingly abfenting themfelves from their benefices, for one month together, or two months in the year, incur a penalty of 5 1. to the king, and 5 1. to any perfon that will fue for the fame ; ex¬ cept chaplains to the king, or others therein mention¬ ed, during their attendance in the houfehold of fuch as retain them : and alfo except all heads of houfes, magiftrates, and proftffors in the univerfities, and all Undents under forty years of age refiding there, bona fide, for fludy. Legal refidence is not only in the pa¬ rifh, but alfo in the parfonage-houfe ; for it hath been refolved, that the ftatute intended refidence, not only for ferving the cure and for hofpitality, but alfo for maintaining the houfe, that the fucceffor alfo may keep hofpitality there. We have feen that there is but one way whereby one may become a parfon or vicar: there are many ways by which one may ceafe to be fo. 1. By death. 2. By ceffion, in taking another benefice ; for by fta¬ tute 21 Hen. VIII. c. 13. if any one having a bene¬ fice of SI. per annum, or upwards, in the king’s books, (according to the prefent valuation), accepts any o- ther, the firft (hall be adjudged void, unhfs he ob¬ tains a difpenfation; which no one is entitled to have but the chaplains of the king and others therein men¬ tioned, the brethren and Tons of lords and knights, and dpftors and bachelors of divinity and law, admit¬ ted by the univerfities of this realm. And a vacancy thus made for want of a difpenfation, is called cefiian. 3. By confecration ; for, as was mentioned before, when a clerk is promoted to a biftropric, all his other preferments are void the inftant that he is confecrated. But there is a method, by the favour of the crown, of bolding fuch livings in commeniam. Commenda, or ec- clefia cQ>nmendata> is a living commended by the crown to the care of a clerk, to hold till a proper pallor is Parfonage, provided for it. This may be temporary for one, two, Parfon.'. or thrde years, or perpetual, being a kind of difpenfa¬ tion to avoid the vacancy of the living, and is called a commenda retinere. There is alfo a commenda recit>erc, which is to take a benefice de novo in the bifhop’s own gift, or the gift of ibme other patron confenting to the fame ; and this is the fame to him as inftitution and induftion are to another clerk. 4. By refigna- tion. But this is of no avail till accepted by the or¬ dinary, into whole hands the refignation muft be made. 5. By deprivation, either by canonical cen- fures, or in purfuance of divers penal ftatutes, which declare the benefice void, for fome nonfeafance or negledf, or elfe fome malefeafance or crime : as for fimony ; for maintaining any doflrine in dero¬ gation of the king’s fupremacy, or of the thirty-nine articles, or of the book of common-prayer; for ne- gle&ing after inftitution to read the liturgy and ar¬ ticles in the church, or make the declarations againft popery, or take the abjuration-oath ; for uiing any other form of prayer than the liturgy of the church of England ; or for abfenting himfelf 60 days in one year from a benefice belonging to a popifti patron, to which the clerk was prefented by either of the univerfities: in all which, and fimilar cafes, the benefice is ipfo fatta void, without any formal fentence of deprivation. PARSONAGE, a reftory, or parifti-church, en¬ dowed with a glebe, houfe, lauds, tithes, &c. for the maintenance of a rainifter, with cure of fouls within fuch pariftr. See Parson. PARSONS, or Persons, (Robert), an eminent writer of the church of Rome, was born at Nether- Stowey, near Bridgewater, in Somerfet(hire, in 1546, and educated at Baliol college, Oxford, where he diftinguiftied himfelf as a zealous Proteftant and an a- cute difputant; but being charged by the fociety with incontinency and embezzling the college money, he went to Flanders, and declared himfelf a Catholic. After travelling to feveral other places, he effe&ed the eftabliftiment of the Englifti feminary at Rome, and procured father Alien to be chofen re&or of it. He himfelf was appointed the head of the million to Eng¬ land, in order to dethrone Queen Elizabeth, and if pofiible extirpate the Proteftant religion. He accor¬ dingly came over to this kingdom in 1580, and took fome bold fteps towards accomplilhing his purpofe, in which he concealed himfdf with great art, travelling about the country to gentlemens houfes, difguifed in the habit, fometimes of a foldier, fometimes of a gen¬ tleman, and at other times like a minifter or an appa¬ ritor ; but father Campian being feized and committed to prifon, our author efcaped out of England for fear of the fame fate, and went to Rome, where he was made redor of the Englifh feminary. He had long entertained the moft fanguine hopes of converting to the popilh faith the young king of Scots, which he confidered as the beft and moil effedual means of- bringing over his fubjeds to the fame religious prin¬ ciples ; but finding it impoffible to fucceed in his de- fign, he publiftied, in 1594, his celebrated book, un¬ der the feigned name o( Dolejnan, in order to over¬ throw, as far as lay in his power, the title of that prince to the crown of England. He died at Rome ia 1610, and was buried in ;he chapd of the Englifh PAR [ 5883 ] PAR Part Parthia. college. Befitles the book already mentioned, he wrote, 1 A defence of thfe Catholic hierarchy. 2. The liturgy of the facrament of the mafs. 3. A memorial for the Reformation; and feveral other tradds. PART, a portion of fome whole, coniidered as di¬ vided or divifible. Aliquot Part, is a quantity which, being repeated any number of times, becomes equal to an integer. Thus 6 is an aliquot part of 24, and 5 an aliquot part of 30, &c. Aliquant Part, is a quantity which, being repeated any number of times, becomes always either greateror lefs than the whole. Thus 5 is an aliquant part of i 7, and 9 an aliquant part of 10, &c. The aliquant part is refolvible into aliquot parts. Thus 15, an aliquant part of 20, is refolvible into 10^, and 5 a fourth part of the fame. Parts of fpeeck, in grammar, are all the forts of words which can enter the compofuion of a difeourfe. See Grammar. PARTERRE, in gardening, a level divifion of ground, which for the mod part faces the foutb, or bell front of a houfe, and is generally furnilhed with ever-greens, flowers, &c. There are two kinds of thefe, the plain ones and the parterres of embroidery. Plain parterres are moll valuable in England, be* caufe of the firmnefs of the Englilh grafs turf, which is fuperior to that of any other part of the world ; and the parterres of embroidery are cut into Iheil and fcroll work, with alleys between them. An oblong, or long fquare, is accounted the mod proper figure for a parterre ; and a parterre Ihould indeed be always twice as long as it is broad, becaufe, according to the known laws of perfpective, a long fquare always links to a fqnare; and an exadl fquare always appears lefs than it really is. As to the breadth of a parterre, it is to be proportionable to the front of the houfe; but lefs than too feet in breadth is too little. There Ihould be on each fide the parterre a terras- vvalk raifed for • view, and the flat of the parterre be¬ tween the terrafes Ihould never be more than 300 feet, at the utmod, in breadth, and about 140 feet in width, with twice and a half that in length, isedeem- ed a very good fisre and proportion. PARTHIA, a celebrated empire of antiquity, bounded on the wed by Media, on the north by Hyr- cania, on thread by Aria, on the fouth by Carmania the defart ; furrounded on every fide by mountains, which dill ferve as a boundary, though its name is now changed, having obtained that of Eyrac or Arak; and, to didinguilh it from Chaldaea, that of Eyrac Agami. Ey Ptolemy it is divided into five didridls, 1 viz. Caminfine, or Gamifene, Parthyene, Choroane, Ancient di-^tt;cene an(j Tabiene. The ancient geographers enumerate a great many cities m this country. Ptole¬ my in particular reckons 25 large cities ; and it cer¬ tainly mud have been very populous, fince we have accounts of 2.000 villages, befides a number of cities, in this didrid. being deflroyed by earthquakes. Its capital was named Hecatompolis, from the circumdance of.its having loo gates. It was a noble and magni¬ ficent place ; and, according to fome, it dill remains under the name of Ifpahan, the capital of the prefent Perfian empire. Earthia is by fome fuppofed to have been firft peo¬ pled by the Phetri cr Pathri, often mentioned in ferip- Parthia. lure, and will have the Parthians to be defeended from Patbrufim the fon of Mifraim. But however true this Whence may be with regard to the ancient inhabitants, yet itPe°pk jeftion the Mardi, who had never been conquered by any but Alexander the Great. After him, bis brother Mithridates was inveded with the regal dignity. He reduced the Badrians, Medes, Perlians, Eiytneans, and over-ran in a manner all the ead, penetrating be¬ yond the boundaries of Alexander’s conquefts. Ee- pie;rius Nicator, who then reigned in Syria, endea¬ voured; PAR [ 5884 ] PAR Partllia- vouved to recover thofe provinces; but bis army was entirety deftroyed, and himfelf taken prifoner, in which Hate he remained till his death ; after which victory Mithridates made himfelf mafter of Babylonia and Mefopotamia, fo that he now commanded all the -provinces from hefween the Euphrates and the Ganges. Mithridates died in the 37th year of his reign, and left the throne to his fon Phrahates II. whowasfcarce s fettled in his kingdom, when Antiochus Sidetes Antiochus marched againft him at the head of a numerous army, Sidetes de- under pretence of delivering his brother Demetrius, ftroyedwith who was ftiil in captivity. Phrahates was defeated in Ins whole three pitched battles, in confequence of which he loft @rn,Jr’ all the countries conquered by his father, and was re¬ duced within the limits of the ancient Parthian king¬ dom. Antiochus did not, however, long enjoy his good fortune ; for his army, on account of their num¬ ber, amounting to no fewer than 400,000, being obli¬ ged to feparate to fuch diftances as prevented them, in cafe of any fudden attack, from joining together, the inhabitants, whom they had molt cruelly opprefs- ed, taking advantage of this feparation, confpired with the Parthians to deftroy them. This was accord¬ ingly executed; and the vaft army of Antiochus, with the monarch himfelf, were flaughtered in one day, fcarce a Angle perfon efcaping to carry the news to Syria. Phrahates, elated with this fuccefs, propofed to invade Syria ; but in the mean time, happening to quarrel with the Scythians, he was by them cut off with his whole army, and was fucceeded by his uncle Artabanus. The new king enjoyed his dignity but a very fhort time, being, a few days after his aecefiion, killed in another battle with the Scythians. He was fucceeded 6 by Pacorus I. who entered into an alliance with the Alliance Romans; and he by Phrahates III. This monarch concluded took under his proteflion Tigranes the fon of Ti- wiih the granes the Great, king of Armenia, gave him his Romans. daughter in marriage, and invaded the kingdom with a defign to place the fon on the throne of Armenia ; but on the approach of Pompey he thought proper to retire, and foon after folemnly renewed the treaty with the Romans. Phrahates was murdered by his children Mithridates and Orodes; and foon after, the former was put to death by his brother, who thus became foie mafter of the Parthian empire. In his reign happened the me- Crcefus re- morable war with the Romans under Craffus. This tblves on a was occafioned not by any breach of treaty on the fide war with of the Parthians, but through the fhameful avarice of the Par- Craffus. The whole Roman empire at that time had * lans■ been divided between Cssfar, Pompey, and Craffus ; and by virtue of that partition, the eaftern provinces had fallen to the lot of Craffus. No focner was he in- velted with this dignity, than he refolved to carry the war into Parthia, in order to enrich himfelf with the fpoils of that people, who were then looked upon to be very wealthy. Some of the tribunes oppofed him, as the Parthians had religioufly obferved the treaty ; but Craffus having, by the alfiftance of Pompey, car¬ ried every thing before him, left Rome in the year $5 B. C. and purfued his march to Brundufium, where he immediately embarked his troops, though the wind blew very high; and after a difficult paffage, where he loft many of his ffiips, he reached the ports of Ga- Parthia. latia. § From Galatia Craffus haftened to Syria, and pafs- Plunders ing through Judea,plundered the temple of Jerufalemthe temP!e in his way. He then marched with as great expedi-^eru a' tion as he could to the river Euphrates, which he croffed on a bridge of boats; and, entering the Par¬ thian dominions, began hoftilities. As the enemy had not expefted an invafion, they were quite unprepared for reliftance, and therefore Craffus over-ran all Me¬ fopotamia ; and if he had taken advantage of the con- fternation which the Parthians were in, might have alfo reduced Babylonia. But inflead of this, early in the autumn, he repaffed the Euphrates, leaving only 7000 foot and 1000 horfe to garrifon the places he had reduced ; and putting his army into winter-quar¬ ters in Syria, gave himfelf totally up to his favourite paffion of amaffing money. Early in the fpring, the Roman general drew his forces out of their winter-quarters, in order to purfue the war with vigour; but, during the winter, Orodes had collefted a very numerous army, and was well prepared to oppofe him. Before he entered upon ac¬ tion, however, the Parthian monarch fent ambaffadors to Craffus, in order to expoftulate with him on hisin- juftice in attacking an ally of the Roman empire; but Craffus, without attending to what they faid, only re¬ turned for anfwer, that “ they fhould have his anfwer at Seleucia.”. Orodes, finding that a war was not to be avoided, divided his army into two bodies. One he command¬ ed in perfon, and marched towards Armenia, in order to oppofe the king of that country, who had raifed a confiderable army to afiift the Romans. The other he fent into Mefopotamia, under the command of Sure- ^ na or Surenas, a moft experienced general, by whofe His ipldiers conduft all the cities which Craffus had reduced were difteart- quickly retaken. On this fome Roman foldiers whoened* made their efcape, and fled to the camp of Craffus, filled the minds of his army with terr at the accounts of the number, power, and ftrength of the enemy. They told their fellow-foldiers, that the Parthians were very numerous, brave, and well difeiplined; that it was impoffible to overtake them when they fled, or efcape them when they purfued ; that their defenfive weapons were proof againft the Roman darts, and their offenfive weapons fo lharp, that no buckler was proof againft them, &c. Craffus looked upon all this only as the effe&s of cowardice ; but the common fol¬ diers, and even many of the chief officers, were fo dif- heartened, that Caffius, the fame who afterwards con¬ fpired againft Casfar, and moft of the legionary tri¬ bunes, advifed Craffus to fufpend his march, and con- fider better of the enterprife before he proceeded far¬ ther in it. But Craffus obftinately perfifted in his for¬ mer refolution, being encouraged by the arrival of Ar- tabazus king of Armenia, who brought with him 6000 horfe, and promifed to fend 10,000 cuiraffiers and 30,000 foot, whenever he fliould Hand in need of them. At the fame time, he advifed him by no means to march his army through the plains of Mefo¬ potamia, but to take his route over the mountains of Armenia. He told him, that as Armenia was a mountainous country, the enemy’s cavalry, in which their main ftrength confifted, would there be entirely PAR [ 5885 ] PAR Parthia. ufelefs ; and befides, his army would there be plenti¬ fully fupplied with all manner of neceffaries: whereas, if he marched by the way of Mefopotamia, he would be perpetually harrafled by the Parthian horfe, and fre¬ quently be obliged to lead his army thro’ fandy de¬ farts, where he would be diftreffed for want of water and all other provifions. This falutary advice, how¬ ever, was rejefted, and Craffus entered Mefopotamia with an army of about 40,000 men. The Romans had no fooner crofTed the Euphrates, than Caffius advifed his general to advance to fome of thofe towns in which the garrifons yet remained, in order to halt and refrefli his troops ; or if he did not choofe to follow this advice, he faid that his beft way would be to march along the banks of the Euphrates to Seleucia ; as by this method he would prevent the Parthians from, furrounding him, at the fame time that he would be plentifully fupplied with provifions from 10 his (hips. Of this advice Craffus feemed to approve; Betrayed by but was difluaded by Abgarus king of Edeffa, whom Abgarus the Romans took for an ally, but who was in reality a king of E- traitor fent by Surenas to bring about the deftruftion a* of the Roman army. Under the conduft of this faithlefs guide, the Ro¬ mans entered a vaft green plain divided by many rivu¬ lets. Their march proved very eafy through this fine country; but the farther they advanced, the worfe the roads became, infomuch, that they were at laft obli¬ ged to climb up rocky mountains, which brought them to a dry and fandy plain, where they could nei¬ ther find food to fatisfy their hunger, nor water to quench their thirft. Abgarus then began to be fufpec- ted by the tribunes and other officers, who earneftly intreated Craffus not to follow him any longer, but to retreat to the mountains ; at the fame time an exprefs arrived frem Artabazus, acquainting the Roman ge¬ neral that Orodes had invaded his dominions with a great army, and that he was obliged to keep his troops at home, in order to defend his own dominions. The fame meflenger advifed Craffus in his matter’s name to avoid by all means the barren plains, where his army would certainly periffi with hunger and fa¬ tigue, and by all means to approach Armenia, that they might join their forces againft the common ene¬ my. But all was to no purpofe; Craffus, inftead of hearkening either to the advice of the king or his own officers, firft Hew into a violent paffion with the mef- fengers of Artabazus, and then told his troops, that they were not to expe& the delights of Campania in the moft remote parts of the world. Thus they continued their march for fome days crofs a defart, the very fight of which was fufficient to throw them into the utmoft defpair ; for they could not perceive, either near them or at a diftance, the lead tree, plant, or brook, not fo much as an hill, or a Angle blade of grafs ; nothing was to be feen all around them, but huge heaps of burning fand. The Romans had fcarcely got thro’ this defart, when word was brought them by their fcouts, that a numerous army of Parthians was advancing full march to attack them ; for Abgarus, under pretence of going out on parties, had often conferred with Surenas, and concert¬ ed meafures with him for deftroying the Roman army. Upon this advice, which occafioned great confufion in the camp, the Romans being quite exbaufted and ti¬ red out with their long and troublefome march, Craf- Parthia. fus drew up his men in battalia, following at firft: the' advice of Caffius, who was for extending the infantry as wide as poffible, that they might take up the more ground, and by that means prevent the enemy from furrounding them ; but Abgarus affuring the procon- ful, that the Parthian forces were not fo numerous as was reprefented, he changed this difpofition, and be¬ lieving only the man who betrayed him, drew up his troops in a fquare, which faced every way, and had on each fide 12 cohorts in front. Near each cohort, he placed a troop of horfe toffipport them, that they might charge with the greater fecurity and boldnefs. Thus the whole army looked more like one phalanx, than troops drawn up in manipuli, with fpaces be¬ tween them, after the Roman manner. The general himfelf commanded in the centre, his fon in the left wing, and Caffius in the right. In this order they advanced to the banks of a fmali river called the Balijpus, the fight of which was very pleafing to the foldiers, who were much harraffed with drought and exceffive heat. Moft of the officers were for encamping on the banks of this river, or ra ¬ ther rivulet, to give the troops time to refrelh them- felves after the fatigues of fo long and painful a march; and, in the meantime, to procure certain in¬ telligence of the number and difpofition of the Par¬ thian army ; but Craffus, fuffering himfelf to be hur¬ ried on by the inconfiderate ardour of his fon, and the horfe he commanded, only allowed the legions to take a meal Handing ; and before this could be done by all, he ordered them to advance, not flowly, and halt¬ ing now and then, after the Roman manner, but as fall as they could move, till they came in fight of the enemy, who, contrary to their expedition, did not appear either fo numerous or fo terrible as they had been reprefented ; but this was a ftratagem of Surenas, who had concealed his men in convenient places, or- Ir dering them to cover their arms, left their brightnefsThe battle fhould betray them, and, ftarting up at the firft fignal,of Canha?. to attack the enemy on all fides. The ttratagem had the defired effedt; for Surenas no fooner gave the fig- nal, than the Parthians, rifing as it were out of the ground, with dreadful cries, and a moft frightful noife, advanced againft the Romans, who were greatly fur- prifed and difmayed at that fight; and much more fo, when the Parthiaus, throwing off the covering of their arms, appeared in finning cuiraffes, and helmets of burniihed fteel, finely mounted on horfes covered all over with armour of the fame metal. At their head appeared young Surenas, in a rich drefs, and was the firft who charged the enemy, endeavouring, with his pikemen, to break through the firft ranks of the Ro¬ man army ; but finding it too clofe and impenetrable, the cohorts fupporting each other, he fell back, and retired in a feeming confufion : but the Romans were much furprifed when they faw themfelves fuddenly furrounded on all fides, and galled with continual ftiowers of arrows. Craffus ordered his light-armed foot and archers to advance, and charge the enemy ; but they were foon repulfed, and forced to cover themfelves behind the heavy-armed foot. Then the Parthian horfe, advancing near the Romans, difehar- ged (bowers of arrows upon them, every one of which did execution, the legionaries being drawn up in fuch clofe , PAR [ 5886 J PAR Paithia. clofe order, that it was itrvpofiible for the enemy to .mifs their aim. As their arrows were of an extraordi¬ nary weight, and difcharged with incredible force and imgetuofity, nothing was proof againft them. The two wings advanced in good order to repulfe them, but to no effeft ; for the Parthians fhot their arrows with as great dexterity when their backs were turned, as when they faced the enemy ; fo that the Romans, whether they' kept their ground, or purfued the fly¬ ing enemy, were equally annoyed with their fatal ar¬ rows. The Romans, as long as they had any hopes that the Parthians, after having fpent their arrows; would either betake themfelves to flight, or engage them hand to hand, flood their ground with great refolu- tion and intrepidity ; but when they obferved, that there were a great many camels in their rear, loaded with arrows, and that thofe who emptied their qui¬ vers wheeled about to fill them anew, they began to Jofe courage, and loudly to complain of their general for fuffering them thus to Hand Hill, and ferveonly as a butt to the enemy’s arrow's, which, they well faw, would not be exhaufted till they were all killed to a man. Hereupon CrafTus ordered his fon to advance, at all adventures, and attack the enemy with 1300 hoife, 500 archers, and 8 cohorts. But the Parthians no fooner faw tins choice body (for it was the flower of the army) marching up againft them, but they wheeled about, and betook themfelves, according to their cuftom, to flight. Hereupon young Craffus, cry¬ ing out as loud as he could, They fly before us, puflied on full fpeed after them, not doubting but he Ihonld gain a complete vidfory ; but, when he was at a great diftance from the main body of the Roman army, he perceived his miltake ; for thofe who before had fled, facing about, charged him with incredible fury. Young Craffus Ordered his troops to halt, hoping that the ene¬ my, upon feeing their fmall number, would not be afraid to come to a clofe fight : but herein he was likewife greatly difappointed ; for the Parthians, con¬ tenting themfelves to oppofe his front with their heavy¬ armed hoife, furrounded him on all fides; and, keep¬ ing at a diftance, difcharged inceflant fhowers of ar¬ rows upon the unfortunate Romans, thus furrounded and pent up. The Parthian cavalry, in wheeling about, raifed fo thick a dull, that the Romans could fcarce fee one another, much lefs the enemy: never- thelefs, they found themfelves wounded, with arrows, tho’ they could not perceive whence they came. In a fhort time, the place where they flood was all ftrown with dead bodies. Some of the unhappy Romans finding their entrails Extremedi-torn’ anJ many overcoITie by the exquifite torments ftrefs of the they fuffered, rolled themfelves on the fand with the Romans, arrows in their bodies, and expired in that manner. Others endeavouring to tear out by force the bearded points of the arrows, only made the wounds the larger and increafed their pain. Moll of them died in this manner; and thofe who outlived their companions were no more in a condition to aft ; for when young Craf¬ fus exhorted them to march up to the enemy, fome fhewed him their wounded bodies, others their hands nailed to their bucklers, and fome their feet pierced through and pinned to the ground: fo that it was e- qually impofiible for them either to attack the enemy or defend themfelves. The young commander, there- Parthia. fore, leaving his infantry to the mercy of the enemy, advanced at the head of the cavalry againft their heavy¬ armed horfe. The thoufand Gauls whom he had brought with him from the weft, charged the enemy with incredible boldnefs and vigour ; but their lances did little execution on men armed with cuirafles, and horfes covered with tried armour: however, they beha¬ ved with great refolution ; for fome of them taking bold of the enemies fpears, and clofing with them, threw them off their horfes on the ground, where they lay without being able to ftir, by reafon of the great weight of their armour 5 others difmounting, crept un¬ der the enemy’s horfes, and thrufting their fwords into their bellies, made them throw their riders. Thus the brave Gauls fought, tho’ greatly harraffed with heat and third, which they were not accuftomed to bear, till moft of their horfes were killed, and their com¬ mander dangeroufly wounded. They then thought it advifeable to retire to their infantry, which they no fooner joined, than the Parthians invefted them anew, making a moft dreadful havock of them with their ar¬ rows. In this defperate condition, Craffus, fpying a rifing ground at a fmall diftance, led the remains of his detachment thither, with a defign to defend him- fclf in the bell manner he could, till fuccours fltould be fent him from his father. The Parthians purfued him ; and having furrounded him in his new poll, con¬ tinued (howering arrows upon his men, till moft of them were either killed or difabled, without being able to make ufe of their arms, or give the enemy proofs of their valour. Young Craffus had two Greeks with him, who had fettled in the city of Carrhse. Thefe, touched with compaffion, at feeing fo brave a man reduced to fuch ftreights, preffed him to retire with them to the neigh¬ bouring city of Ifchnes, which had declared for the Romans; but the young Roman rejefted their propo- fal with indignation, telling them, that he would ra¬ ther die a thoufand times than abandon fo many valiant men, who ihcrificed their lives for his fake. Having returned this anfwer to his two Greek friends, he em¬ braced and difmiffed them, giving them leave to re¬ tire and fhift for themfelves in the beft manner they could. As for himfelf, having now loft all hopes of being relieved, and feeing moft of his men and friends killed round him, he gave way to his grief; and, not ,3 being able to make ufe of his-arm, which was (hot The death thro’ with a large barbed arrow, he prtfented hisofy°ung fide to one of his attendants, and ordered him to putCraflus‘ an end to his unhappy life. His example was fol¬ lowed by Cenforius, a fenator, by Megabacchus, an experienced and brave officer, and by moft of the no- biiity who ferved under him. Five hundred com¬ mon foldiers were taken prifoners, and the reft cut in pieces. The Parthians, having thus cut off or taken the whole detachment commanded by young Craffus, marched without delay againft his father, who, up¬ on the firll advice that the enemy fled before his fon, and were clofely purfued by him, had taken heart, the more becaufe thofe who had remained to make head againft him, feemed to abate much of their ardour, the greateft part of them having marched with the reft againft his foo. Wherefore, having encouraged his troops, par [ 5887 1 PAR PartMa. troops, lie had retired to a fmal] hill in his rear, to touring city of C'arrhae, which was held by a Roman Partliia. wait there till his fon returned from the purfuit. garrifon.

Hereupon a council of the V.ol. VIII. 1 33 F ck‘c£ PAR [ 5888 j PAR Parthia. chief officers being fummoned, it was thought expe- dient to retire from Carrhse that very night, and fetk for another afylum. It was of the utmoit importance, that none of the inhabitants of Carrhae fbould be ac¬ quainted with their defign till the time of its execu¬ tion ; but Craffus, whofe whole conduft evidently fhews that he was blinded, as Dio Caflius obferves, by fome divinity, imparted the whole matter in con¬ fidence to one Andromachus, choofing him for his guide, and relying injudicioufly on the fidelity of a man whom he fcarce knew. Andromachus immediate¬ ly acquainted Surenas with the defign of the Romans ; promifing at the fame time, as the Parthians did not engage in the night, to manage matters fo, that they fhould not get out of his reach before day break. Pur- fuant to his promife, he led them through many wind¬ ings and turnings, till he brought them into deep' marlhy grounds, where the infantry were up to the knees in mire. Then Cafiius, fufpe&ing that their guide had led them into thofe bogs with no good de¬ fign, refufed to'follow him any longer; and, returning to Carrhae, took his route tpwards Syria, which he reached with 500 horfe. Odavius, with 5000 men under his command, being conduced by trully guides, gained the mountains called by Plutarch and Appian Sitmacl, and there intrenched himfelf before break of day. As for Craffus, he was ftill- entangled in the marfhes, when Surenas, at the riling of the fun, overtook him, and invefted him with his cavalry. The proconful had with him four cohorts, and a fmall body of horfe ; and with thefe he gained, in fpite of all oppofition, the fummit of another hill within 12 furlongs of Oc¬ tavius; who, feeing the danger that threatened his ge¬ neral, flew to his affiftance, firfl: with a fmall number of his men, but was foon followed by all the reft, who, being afhamed of their cowardice, quitted their poll, tho’ very fafe, and, charging the Parthians with great fury, difengaged Craffus, and obliged the enemy to abandon the hill. Upon the retreat of the enemy, they formed themfelves into an hollow fquare; and placing Craffus in the middle, made a kind of rampart round him with their bucklers, refolutely protefting, that none of the enemy’s arrows ftiould touch their ge¬ neral’s body, till they were all killed fighting in his defence. Surenas, loth to let fo fine a prey efcape, furrounded the hill, as if he defigned to make a new attack : but, finding his Parthians very backward, and not doubting but the Romans, when night came on, would purfue their march, and get out of his reach, he had recourfe again to artifice; and declared be¬ fore fome prifoners, whom he foon after fet at li¬ berty, that he was inclined to treat with the pro¬ conful of a peace ; and that it was better to come to a reconciliation with Rome, than to fow the feeds of an eternal war, by (bedding the blood of one of her generals. Agreeable to this declaration, Surenas, as foon as the prifoners were releafed, advanced towards the hill where the Romans were pofted, attended only by fome of his officers, and, with his bow unbent, and open arms, invited Craffus to an interview. So fudden a change feemed very fufpicious to the proconfu!; who therefore declined the interview, till he was forced, by his. own foldiers, to intruff his life with an enemy whofe treachery they had all experienced ; for the le* Parthla. gionaries flocking round him, not only abufed him in an outrageous manner, but even menaced him if he did not accept of the propofals made him by the Par¬ thian general. Seeing, therefore, that his troops were ready to mutiny, he began to advance, without arms or guards, towards the enemy, after having called the gods and his officers to witnefs the violence his troops offered him ; and intreated all who were prefent, but efpecially Odlavius and Petronius, two of the chief commanders, for the honour of Rome their common mother, not to mention, after his death, the fliameful behaviour of the Roman legionaries. Odtavius and Petronius Could not refolve to let him go alone; but attended him down the hill, as did likewife fome le¬ gionaries, keeping at a diftance. Craffus was met at the foot of the hill by two Greeks; who, difmounting from their horfes, fainted him with great refpect ; and defired him, in the Greek tongue, to fend fome of his attendants, who might fatisfy him, that Sure¬ nas, and thofe who were with him, came without arms. Hereupon Craffus fent two brothers, of the Rofcian family ; but.Surenas, having caufed them to be feized, advanced to the foot of the hill, mounted on a fine horfe, and attended by the chief officers of his army. Craffus, who waited for the return of his two meffengers, was furprifed to fee bimftlf prevented by Surenas in perfon, when he lead expe&ed it. The Parthian general, perceiving, as he approached Craf¬ fus, tfut he was on foot, cried out, in a feeming fur- prize, “ What do I fee ? a Roman general on foot, and we on horfeback ! Let an horfe be brought for him immediately.” “ You need not be furprifed, (re¬ plied Craffus;) we are come ordy to an interview, each after the cuftom of his country.” “ Very well, (an- fwered Surenas ;) there (hall be henceforth a lading peace between king Orodes and the people of Rome : but we mud fign the articles of it on the banks of the Euphrates; for you Romans do not always remem- htr your conventions.” Craffus would have fent fort an horfe: but a very ftately one, with a golden bit, and richly caparifoned, was brought to him by a Par¬ thian ; which Surenas prefenting to him, “ Accept this horfe from my hands, (faid he), which I give you in the name of my mafter king Orodes.” He had fcarce uttered thefe words, when fome of the king’s of¬ ficers,. taking Craffus by the middle, fet him upon the horfe, which they began to whip with great violence before them in order to make him quicken his pace. O&avius, offended at this infult, took the horfe by the bridle ; Petronius, and the few Romans who were prefent, feconded him, and flocking all round Craffus, (topped his horfe. The Parthians endeavoured to re- pulfe them, and clear the way for the proconful; whereupon they began to juftle and pu(h one another with great tumult and diforder. At lad, O&avius, drawing his fword, killed one of the king’s grooms ; but, at the fame time, another coming behind Odta- iy riiis, with one blow laid him dead at his feet. BothCrairus. parties fought with great resolution, the Parthians kffied- driving to carry off Craffus, and the Romans to refeue him out of their hands. In this feuffle mod of the Ro¬ mans who came to the conference were killed ; and, among the reft, Craffus himfelf, but whether by a Ro¬ man or a Parthian is uncertain. PAR [ 5889 1 PAR Parthia. Upon his death, the reft of the army either furren- dered to the enemy, or, difpertlng in the night, were purfued, and put to the fword. The Romans loft in this campaign at leaft 30,000 men ; of which 20,000 were killed, and 10,000 taken prifoners. When the battle of Carrhse was fought, king Orodes was in Armenia, where he had made peace with Arta- bazus. While the two kings were folemnizing their new alliance with expenfive and public feafts, Styllaces, or Syllaces, a Parthian officer, whom Surenas had fent with the news of his late vidlory, and the head of Craffus as a proof of it, arrived in the capital of Ar¬ menia. The tranfports of joy which Orodes felt at this fight, and thefe news, are not to be exprefled ; and the lords of both kingdoms, who attended their fovereigns, raifed loud and repeated fhouts of joy. Syllaces was ordered to give a more particular and di- ftinft account of that memorable a&ion: which when he had done, Orodes commanded melted gold to be poured into Craffus’s mouth; reproaching him thereby with avarice, which had been always his predominant paifion. lg Surenas did not long enjoy the pleafure of his Surenas putvi&ory ; for Orodes, jealous of his power and au¬ to death bythority among the Parthians, foon after caufed him Orodes. t0 be pUt t0 death. Pacorus, the king’s favourite fon, was put at the head of the army; and, a- reeable to his father’s diredions, invaded Syria : but e was driven out from thence with great lofs by Ci¬ cero and Caffius, the only general who furvived the defeat of Craffus. After this we find no mention of the Parthians, till the time of the civil war between Caefar and Pompey, when the latter fent ambaffadors to folicit fuccour againft his rival. This Orodes was willing to grant, upon condition that Syria was de¬ livered up to him : but as Pompey would not confent to fuch a propofal, the fuccours were not only denied, but, after the battle of Pharfalia, he put Lucius Hir- tius in irons, whom Pompey had again fent to alkaffi- ftance, or at leaft to defire leave to fhelter himfelf in the Parthian dominions. Caefar is faid to have meditated a war againft the Parthians, which in all probability would have pro¬ ved fatal to them. His death delivered them from ’!> - this danger. But, not long after, the eaftern pro- menced'a* v'nce8» being grievoufly opprefled by Mark An- gainft the thony, rofe up in arms ; and having killed the tax- Parthians gatherers, invited the Parthians to join them, and by Mark drive out the Romans. They very readily accepted Anthony. ^ jnvjtatjon> and croffed the Euphrates with a powerful army under the command of Pacorus and Labienus a Roman general of Pompey’s party. At firft they met with great fuccefs, over-ran all Afia Minor, and reduced all the countries as far as the Hcllefpont and the Egaean Sea, fubduing likewife Phoenicia, Syria, and even Judaea. They did not however long enjoy their new conquelts: for being elated with their vi&ories, and defpifing the enemy, they engaged Venddius, Anthony’s lieutenant, before Labienus had time to join them, and were utterly de¬ feated. This fo diffieartened Labienus’s army, that they all abandoned him; and he himfelf, being thus ob¬ liged to wander from place to place in difguife, was at lalt taken and put to death at Cyprus. Ventidius pur- fuing his advantage, gained feveral other vidories ; and at laft entirely defeated the Parthian army under Parthia. Pacorus, cutting almoft the whole of them in pieces, ^ and the prince himfclf among the reft. He did not, Pacorus de- however, purfue this laft vidory as he might have feateia,'d done; being afraid of giving umbrage to Anthony, who had already become jealous of the great honour Ventl 1US* gained by his lieutenant. He therefore contented himfelf with reducing thofe places in Syria and Phoe¬ nicia which the Parthians had taken in the beginning of the war, until Anthony arrived to take the command of the army upon himfelf. Orodes was almoft diftraded with grief on receiving the dreadful, news of the lofa of his army and the death of his favourite fon. However, when time had refto- red the ufe of his faculties, he appointed Phrahates, theeldeft, but themoft wicked, of all his children, to fucceed him in the kingdom, admitting him at the fame time to a fhare of the fovereign authority with himfelf. The confequence of this was, that Phrahates very foon attempted to poifon his father with hem¬ lock. But this, contrary to expedation, proving a cure for the dropff which an excefs of grief had brought upon the king, the unnatural fon had him0r0(1*J ftifled in bed; and foon after not only murdered all his murjcsretj< own brethren, who were 30 in number, but cut olf all the reft of the royal family, not fparing even his own eldeft fon, left the difeontented Parthians (hould place him, as he was already of age, on the throne. Many of the chief lords of Parthia, being intimi¬ dated by the cruelty of Phrahates, retired into foreign countries ; and among thefe was one Moncefes, a per- fon of great diftindion, as well as fkill and experience in war. This man, having fled to Anthony, foon gained his confidence, and was by him eafily prevailed upon to engage in a war againft his countrymen. But Phrahates, juftly dreading the confequences of fuch a perfon’s defedion, fent a folemn embafly to in¬ vite him home on fuch terms as he Ihould think fit to accept: which greatly provoked Anthony ; though he did not hinder him from returning, left others fhould thereby be difeouraged from coming over to him. He therefore difmifled him with great civility, fending ambafladors at the fame time to Phrahates to treat of a peace. Thus he hoped to divert the Parthian mo¬ narch’s attention from making the neceflary prepara¬ tions for war, and that he ihould be able to fall upon him in the fpring when he was in no condition to make refiftance. But herein he was greatly difap- pointed ; for, on his arrival at the Euphrates, which he intended to pafs, and enter the Parthian dominions on that fide, he found all the pafles fo well guarded, that he thought proper to enter Media, with a defign firft to reduce that country, and then to enter Parthia. This plan had been fuggefted to him by Artabazusy. king of Armenia, who in the end betrayed him ; for, betrayed by inftead of conducing the army the ftraight way from Artabazns Zeugma on the Euphrates, to the A'raxes which parted km8of Ar* Media from Armenia, and which was about 5oo,n^nla, miles diftant from the place whence he firft fet out, Artabazus led them over rocks and mountains fo far about, that the army had marched above 1000 miles before they reached the borders of Media, where they intended to begin the war. Thus they were not only greatly fatigued, but had not fufficient time, the year being far fpent, to put in execution the defign on 33 F 2 which PAR [ 5891 ] PAR Partliia. which they had come. However, as Anthony was ' impatient to get back to Cleopatra, he left behind him moft of the baggage of the army, and 300 wag¬ gons loaded with battering rams and other military engines for fieges ; appointing Statianus, one of his lieutenants, with a body of 10,000 men, to guard them, and to bring them, by flower marches, after the Ten thou- arnty- With the reft of the forces he marched more fand Ro- than 300 miles before the reft, without allowing his mans cut nien any refpite till he arrived at Praafpa, or Phrahata, the capital of Media, which he immediately invefted. But the Parthians, W’dl knowing that he could not make any progrefs without his military machines, paffed by his army, in order to attack Statianus; which they did with fuch fuccefs, that the body commanded by him were all to a man cut off, and all their military engines taken, among which was a battering ram 80 feet long, Anthony, notwithftanding this difafter, continued the fiege of Praafpa ; but was daily haraffed by failles of the garrifon from within, and the enemy’s army without. At laft he began to think of a retreat when his provifions were almoft exhaufted, finding it im- pofiible to become mafter of the city. But as he was to march 300 miles through the enemy’s country, he thought proper firft to fend ambaffadors to the Par¬ thian monarch, acquainting him that the Roman peo¬ ple were willing to allow him a peace, provided he would reftore the ftandards and prifoners taken at Carrhae. Phrahates received the ambaffadors, fitting on a golden throne; and, after having bitterly in¬ veighed againft the avarice and unbounded ambition of the Romans, told them that he would not part with the ftandards and prifoners; but that, if Antony would immediately raife the fiege of Praafpa, he would fuffer him to retire unmolefted. j*4 v Anthony, who was reduced to great ftraits, no ' leaves Par- fooner received this anfwer, than he broke up the fiege, thia in great and marched towards Armenia. However, Phrahates diftrefs. was not fo good as his word ; for the Romans were attacked by the enemy no fewer than 18 times on their march, and were thrice in the utmoft danger of being cut off. A famine alfo raged in the Roman army ; upon which they began to defcrt to the enemy ; and indeed Anthony would probably have been left by himfelf, had not the Parthians, in a very cruel as well as impolitic manner, murdered all thofe who fled to them in fight of the reft. At laft, after having loft 32,000 men, and being reduced to fuch defpair that he was with difficulty prevented from laying vio¬ lent hands on himfelf, he reached the river Araxes ; when his men, finding themfclves out of the reach of the enemy, fell down on the ground, and kiffedit with tears of joy. Antony was no fooner gone, than the kings of Me¬ dia and Parthia quarrelled about the booty they had taken ; and after various contefts, Phrahates reduced all Media and Armenia. After this, being elated with his conquefts, he oppreffed his fubje&s in fnch a cruel and tyrannical manner, that a civil war took place ; in which the competitors were alternately driven out and reftored, till the year 50, when one Vologefes, the fon of Gotarzes, a former king, became peaceable poffcf- for of the throne. He carried on fome wars againft the Romans, but with very indifferent fugcefs, and at laft gladly confented to a renewal of the ancient trea- Partbia. ties with that powerful people. *Ts * From this time the Parthian hiftory affords nothing Parthiafub- remarkable till the reign of the emperor Trajan ; when dued by the Parthian king, by name Cofdroes, infringed theTrajaI1' treaty with Rome, by driving out the king of Arme¬ nia. Upon this Trajan, who was glad of any pre¬ tence to quarrel with the Parthians, immediately ha- flened into Armenia. His arrival there was fo fudden and unexpefted, that he reduced almoft the whole country without oppofition; and took prifoner Par- thamafiris, the king whom the Parthians had fet up. After this he entered Mefopotamia, took the city of Nifibis, and reduced to a Roman province the whole of that wealthy country. Early in the fpring of the following year, Trajan, who had kept his winter-quarters in Syria, took the field again ; but was warmly oppofed by Cofdroes. He found him encamped on the banks of the Eu¬ phrates, with a defign to elifpute his paffage: which he did with fuch vigour, that the emperor, after having feveral times attempted to ford that river, and been always repulfed with great flaughter, was obliged to caufe boats to be built on the neighbouring mountains, which he privately conveyed from thence on carriages to the water-fide ; and having in the night-time form¬ ed a bridge with them, he paffed his army the next day ; but not without great lofs and danger, the Par¬ thians harraffing his men the whole time with inceffant fhowers of arrows, which did great execution. Ha¬ ving gained the oppofite bank, he advanced boldly in¬ to Affyria, the Parthians flying every where before him, and made himfelf mafter of Arbela. Thence he purfued his march; fubduing, with incredible rapidity, countries where the Roman ftandard had never been difplayed before. Babylonia, or the province of Ba¬ bylon, voluntarily fubmitted to him. The city itfelf was, after a vigorous refiflance, taken by ftorm ; by which means he became mafter of all Chaldea and Af¬ fyria, the two richeft provinces of the Parthian em¬ pire. From Babylon he marched to Ctefiphon, the metropolis of the Parthian monarchy ; which he be- fieged, and at laft reduced. But as to the particulars of thefe great conquefts, we are quite in the dark; this expedition, however glorious to the Roman name, be¬ ing rather hinted at, than deferibed, by the writers of thofe times. While Trajan was thus making war in the heart of the enemy’s cosntry, Cofdroes, having re¬ cruited his army, marched into Mefopotamia, with a defign to recover that country, and cut off all commu¬ nication between the Roman army and Syria. On his arrival in that province, the inhabitants flocked to him from all parts ; and moft of the cities, driving out the garrifons left by Trajan, opened their gates to him. Hereupon the emperor detached Eucius and Maximus, two of his chief commanders, into Mefopotamia, to keep fuch cities in awe as had not revolted, and to open a communication with Syria. Maximus was met by Cofdroes ; and having ventured a battle, his army was entirely "defeated, and himfelf killed. But Lucius being joined by Euricius and Clarius, two othercom- mauders fent by Trajan with frefh fupplies, gained confiderable advantages over the enemy, and retook the cities of Nifibis and Seleucia, which had revolted. And now Trajan, feeing himfelf poffeffed of all the beli PAR [ 5891 ] PAR Parthia. beft and mofl:' fruitful provinces of the Parthian em- ' pire; but at the fame time being well apprifed that he . could not, without a vaft expence, maintain his con- queils, nor keep in fubjedlion fo fierce and warlike a people at fuch a diftance from Italy; refolved to fct over them a king of his own choofing, who fhould hold the crown of him and his fuccefiors, and acknowledge them as hi* lords and fovereigns. With this view he repaired to Ctefiphon ; and having there aflembled the chief men of the nation, he crowned one of the royal Parthanaf- byname Partkanafpates, king of Parti.;a, ob» pates ap- liging all who were prelent to pay him their alle- pointed giance. He chofe Parthanafpates, becaufe that prince king by the jjgj j0;ne(j bim at his firlt entering the Parthian domi- pe^or^but n'on3> condndfed him with great fidelity, and fhown foon after on all occafions an extraordinary attachment to the driven out. Romans. Thus the Parthians were at laft fubdued, and their kingdom made tributary to Rome. But they did not long continue in this ftate of fubjedtion : for they no fooner heard of Trajan’s death, which hap¬ pened Ihonly after, than, taking up arms, they drove Parthanafpates from the throne ; and, recalling Cof-, droes, who had retired into the country of the Hyr- canians, openly revolted from Rome. Adrian, who was.then commander in chief of all the forces in the eaft, and foon after acknowledged emperor by the ar¬ my, did not care, though he was at that time in Sy¬ ria with a very numerous army, to engage in a new war with the Parthians ; but contented himfetf with preferving the ancient limits of the empire, without any ambitious profpedts of further conquefls. There¬ fore, in the beginning of his reign, he abandoned tbofe provinces beyond the Euphrates which Trajan had conquered; withdrew the Roman garrifons from Me- fopotamia ; and, for the greater fafety of other places, made the Euphrates the boundary of and barrier in thofe parts, polling his legions along the banks of that river. Unfuccefs- Cofdroes died after a long reign, and was fucceeded f»l wars of by his eldelt fon Vologefes : in whofe reign the Alani Vologefes breaking into Media, then fubjedt to the Parthians, R^ma^s committed there great devaftations ; but were prevail- omans. Up0n, with rich prefents fent them by Vologefes, to abandon that kingdom, and return home. Upon their retreat, Vologefes, having no enemy to contend with at home, fell unexpectedly upon Armenia ; fur- prifed the legions there ; and having cut them all in pieces to a man, entered Syria ; defeated with great flaughter Attilius Cornelianus, governor of that pro¬ vince; and advanced, without oppofition, to the neigh¬ bourhood of Antioch ; putting every where the Ro¬ mans, and thofe who favoured them, to the fword. Hereupon the emperor Verus, by the advice of his colleague Antoninus furnamed the Philofopber, leaving Rome, haftened into Syria : and having driven the Parthians out of that province, ordered Statius Prif- eus to invade Armenia; and Caffius, with Martius Ve¬ rus, to enter the Parthian territories, and carry the war into the enemy’s country. Prifcus made himfclf mailer of Artaxata ; and in one campaign drove the Parthians, though not without great lofs on his fide, quite out of Armenia. Cafiius, on the other hand, having, in feveral encounters, defeated Vologefes, tho* he had an army of 400,000 men under his command, reduced, in four years time, all thofejproVincea which had formerly fubmitted to Trajan, took Seleucia, Parthia. burnt and plundered the famous cities of Babylon and Ctefiphon, with the ftately palaces of the Parthian monarchs, and ftruck terror into the moll remote pro¬ vinces of that great empire. On his return, he loll above half the number of his forces by ficknefs and famine; fo that, after all, the Romans, as Spartianus obferves, had no great reafon to boall of their vidlo- ries and conquefts. However, Verus, who had never fiirred during the whole time of the war from Antioch and Daph¬ ne, took upon him the lofty titles of Parthicus and Armenicus, as if he had acquired them jullly in the midll of his pleaftires and debaucheries. After the revolt and death of Cafiitis, Antoninus the Phi - lofopher repaired into Syria to fettle the affairs of that province. On his arrival there, he was met by ambaffadors from Vologefes; "who having recovered moll of the provinced fubdued by Caffius, and being unwilling ei¬ ther to part with them or engage in a new war, fob- cited the emperor to confirm him in the poffeffion of them, promifing to hold them of him, and to acknow¬ ledge the fovereignty of Rome. To thefe terms Anto¬ ninus readily agreed, and a peace was accordingly concluded between the two empires ; which Vologefes did not long enjoy, being foon after carried off by a dillemper, and not murdered by his own fubjefts, as we read in Conllantinus Manaffcs, who calls him Bek- gefes. j8 Upon his death, Vologefes III. the fon of his bro- Ctefiphoa ther Sanatruccs, and grandfon of Cofdroes, was rai-taken by fed to the throne. He fided with Niger againlt the°everus- emperor Severus: who thereupon, having fettled mat¬ ters at home, marched with all his forces againft him; and advancing to the city of Ctefiphon, whither he had retired, laid clofe fiege to that metropolis. Volo¬ gefes made a mod gallant defence ; but the city, after a long fiege, and much bloodlhed on both fides, was at length taken by affault. The king’s treafures, with his wives and children, fell into the emperor’s hands ; but Vologefes himfelf had the good luck to make his efcape ; which was a great difappointment to Severus, who immediately difpatched an exprefs to acquaint the fenate with the fuceefs that had attended him in his expedition againll the only nation that was then for¬ midable to Rome. But he had no fooner croffed>the Euphrates, than Vologefes recovered all the provinces,, except Mefopotamia, which he had reduced. Thefe expeditions were chargeable to the Romans, and coft them much blood,, without reaping any advantages from them ; for as they had not fufficient forces to keep in awe the provinces they had .fubdued, the in¬ habitants, greatly attached to the family of Arfaces, never failed to return to their ancient obedience as foon as the Roman armies were withdrawn. Vologe¬ fes was foon after engaged in a war flill more trouble- fome and deftru&ive, with his brother Artabanus,, who, encouraged by fome of the difcontented nobles, attempted to rob him of the crown, and place it on his own head. Vologefes gained feveral vittories over his brother and rebellious fubje&s; but died before he could reftore the empire to its former tranquillity. Artabanus, who had-a numerous army at his devo¬ tion, did not meet with any oppofition in feizing the throne, vacant by the death of his brother, though Tirii-- - PAR [ 5892 ] PAR ffarthia. Tiridates had a better title to it, as being his cider brother. He had fcarce fettled the affairs of his king- dom, when the emperor Caracalla, defirous to figna- lize himfelf, as feveral of his predeceflbrs had done, by fotne memorable exploit againft the Parthians, fent a folemn embafly to him, defiring his daughter in marriage. Artabanus, overjoyed at this propofal, which he thought would be attended with a lading peace between the two empires, received the ambaffa- dors with all poffible marks of honour, and readily Infamous complied with their requeft. Soon after, Caracalla treachery of fent a fecond embafly, to acquaint the king that he the emperor was com;ng to folemnife the nuptials; whereupon Ar- Caraca a. tabanus went to meet him, attended with the chief of the nobility and his bell troops, all unarmed, and in moft pompous habits : but this peaceable train no fooner approached the Roman army, than the fol- diers, on a fignal given them, falling upon the king’s retinue, made a moft terrible daughter of the unarm¬ ed multitude ; Artabanus himfelf efcaping with great difficulty. The treacherous Caracalla, having gained by this exploit great booty, and, as he thought, nolefs glory, wrote a long and boafting letter to the fenate, afiuming the title of Parthicus for this piece of trea¬ chery ; as he had before that of Germanicus, for murdering, in like manner, fome of the German no¬ bility. Artabantis, refolving to make the Romans pay dear for their inhuman and barbarous treachery, raifed the moft numerous army that had ever been known in Par- thia, croffed the Euphrates, and entered Syria, put¬ ting all to fire and fword. But, Caracalla being mur¬ dered before this invafion, Macrinus, who had fuc- ceeded him, met the Parthians at the head of a mighty army, compofed of many legions, and all the auxilia- A defperate”63 t^,e ftates °f Alia. The two armies no fooner battle be- came in fight of each other, but they engaged with tween the the utmoft fury. The battle continued two days; an^R8"* R°mans ai,d Parthians fighting fo obftinately, mans.0" that on^y Parted them, without any apparent advantage on either fide ; though both retired, when night had put an end to the conteft, crying, Vic¬ tory, victory. The field of battle was covered all over with dead bodies, there being already above 40,000 killed, including both Romans and Parthians : never- thelefs Artabanus was heard to fay, that the battle was only begun, and that he would continue it till ei¬ ther the Parthians or Romans were all to a man cut in pieces. But Macrinus, being well apprifed that the king came highly enraged againft Caracalla in particular, and dreading the confequences which would attend the deftruftion of his army, fent an herald to Artabanus, acquainting him with the death of Cara¬ calla, and propofing an alliance between the two empires. The king, underftanding that his great enemy was dead, readily embraced the propofals of peace and amity, upon condition that all the prifoners who had been taken by the treachery of Caracalla ffiould be immediately reftored, and a large fum of money paid him to defray the expences of the war. Thefe articles being performed without delay or hefitation, Artabanus returned into Parthia, and Ma¬ crinus to Antioch. As Artabanus loft on this occafion the flower of his army, Artaxerxes, a Perfian of mean defeent, but of great courage and experience in war, revolting Parti from the Parthians, prevailed on his countrymen to I join him, and attempt the recovery of the fovereign 1>arti*~an‘ power, which he faid they had been unjuftly deprived 3* of, fit ft by the Macedonians, and afterwards by the Per* Parthians their vaffals. Artabanus, upon the news of*iajS0”^ f’ this revolt, marched with the whole ftrength of bisthrewthe kingdom to ftipprefs it; but being met by Artaxerxes, Parthian at the head of a no lefs powerful army, a bloody bat-emP,re’ tie enfued, which is faid to have lafted three days. At length the Parthians, though they behaved with the utmoft bravery, and fought like men in defpair, were forced to yield to the Perfians, who were commanded by a more experienced leader. Moft of their troops were cutoff in the flight; and the king himfelf was taken prifoner, and foon after put to death by Artaxerxes’s order. The Parthians, having loft in this fatal en¬ gagement both their king and their army, were forced to fubmit to the conqueror, and become vaffals to a nation which had been fubjeft to them for the fpace of 475 years.

PARTI, Paktie, Party, or Parted, in heraldry, is applied to a fliield or cfcutcheon, denoting it divi¬ ded or marked out into partitions. Parti per pale, is when the fhield is divided perpen¬ dicularly into two halves, by a cut in the middle from top to bottom. Parti per fefs, is when the cut is acrofs the middle, from fide to fide. Parti per bend dexter, is when the cut comes from the upper corner of the fhield on the right hand, and defeends athwart to the oppofite lower corner. Parti per bend fmifter, is when the cut, coming from the upper left corner, defeends acrofs to the op¬ pofite lower one. All thefe partitions, according to M. de la Colom- biere, have their origin from the cuts and bruifes that have appeared on ffiields after engagements ; and, be¬ ing proofs of the dangers to which the bearers had been expofed, they gained them efteem : for which reafon they were tranfmitted to pofterity, and be¬ came arms and marks of honour to their future fa¬ milies. PARTICIPLE, in grammar, an adjeftive formed of a verb; fo called, becaufe it participates partly of the properties of a noun, and partly of thofe of a verb. See Grammar, PARTICLE, in phyfiology, the minute part of a body, an affemblage of which conftitutes all natural bodies. Particle, in grammar, a denomination for all thofe fmall words that tie or untie others, or that exprefs the modes or manners of words. See Cram¬ mer. PARTISAN, in .the art of war, a perfon dextrous in commanding a party ; who, knowing the country well, is employed in getting intelligence, or furpri- fing the enemy’s convoy, &c. The word alfo means an officer fent out upon a party, with the command of a body of light troops, generally under the apellation of the partifans corps. It is alfo neceffary that this corps ftiould be compofed of infantry, light-horfe, and huffars. PA- PAR [ 5893 ] PAR Parmerfhip PARTNERSHIP, is a cantraft among two or more perfons, to carry on a certain bufiners, at their joint expence, and fhare the gain or lofs which arifes from it. Of this there are four kinds. I. Oecafional joint trade, where two or more mer¬ chants agree to employ a certain fum in trade, and divide the gain or lofs fo foon as the adventure is brought to an iffue. This kind of contraft being generally private, the parties concerned are not liable for each other. If one of them purchafe goods on truft, the furnifher, who grants the credit through confidence in him alone, has no recourfe, in cafe of his infolvency, againll the other partners. They are only anfwerable for the (hare of the adventure that be¬ longs to the infolvent partner. If it be propofed to carry the adventure further than originally agreed on, any partner may with¬ draw his intereft ; and, if it cannot be feparated from the others, may infill that the whole lhall be brought to an iffue. II. Standing companies, which are generally clla- blilhed by written contrail between the parlies, where the ftock, the firm, duration, the divifion of the gain or lofs, and other circumftances, are inferted. All the partners are generally authorifed to fign by the firm of the company, though this privilege may be confined to fome of them by particular agree¬ ment. The firm ought only to be fubferibed at the place where the copartnery is eftablilhed. If a part¬ ner has oecafion, when abfent, to write a letter re¬ lating to their affairs, he fubferibes his own name on account of the company. When the fame partners carry on bufinefs at different places, they generally choofe different firms for each. The fignature of each partner is generally fent to new correfpondents; and, when a partner is admitted, although there be no al¬ teration in the firm, bis fignature is tranfmitted, with an intimation of the change in the copartnery, to all their correfpondents. Houfes that have been long eftablilhed, often retain the old firm, though all the original partners be dead or withdrawn. The powers of each partner are, in general, dif- cretionary ; but they ought not to adl, in matters of importance, without confulting together, when there is an opportunity. No partner is liable to makegood the lofs arifing from his judging wrong in a cafe where he had authority to aft. If be exceeds his power, and the event prove unfuccefsful, he mull bear the lofs; but, if it prove fuccefsful, the gain belongs to the company: yet, if he acquaints the company im¬ mediately of what he has done, they mull either ac- quiefee therein, or leave him the chance of gain, as well as the rilk of lofs. All debts contrafted under the firm of the company are binding on the whole partners, though the money was borrowed by one of them for his private ufe, with¬ out the confent of the reft. And, if a partner exceeds bis power, the others are neverthelefs obliged to im¬ plement his engagements; tho’ they may render him refponfible for his milbehaviour. Although the fums to be advanced by the part¬ ners be limited by the contraft, if there be a neceflity for raifing more money to anfwer emergencies or pay the debts of the company, the partners mull furnilh what is DeceHary, in proportion to their /hares. A debt to a company is not cancelled by the pri- Partneifhip vate debts of the partner; and, when a partner becomes^ infolvent, the company is not bound for his debts be¬ yond the extent of his ftiare. The debts of the company are preferable, on the company’s effefts, to the private debts of the part¬ ners. Partnerlhip is generally diffolved by the death of a partner: yet, when there are more partners than two, it may, by agreement, fubfift among the furvivors. Sometimes it is llipulated, that, in cafe of the death of a partner, his place fliall be fupplied by his fon, or fome other perfon condefcended on. The contraft ought to fpecify the time and manner in which the furviving partners Ihall reckon with the executors of the deceafed for his (hare of the ftock, and a reafon- able time allowed for that purpofe. When partnerlhip is diffolved, there are often out- llanding debts that cannot be recovered for a long time, and effefts that cannot eafily be difpofed on. The partnerlhip, though diffolved in other refpefts. Hill fubfifts for the management of their outftanding affairs; and the money arifing from them is divided among the partners, or their reprefentatives, when it it is recovered. But, as this may protraft the final fettlement of the company’s affairs to a very inconve¬ nient length, other methods are fometimes ufed to bring them to a conclufion, either in confequence of the original contraft, or by agreement at the time of diffolution. Sometimes the debts and efttfts are fold by auftion ; fometimes they are divided among the partners; and, when there are two partners, one di¬ vides them into lhares, as equal as poffible, and the other choofes either lhare he thinks belt. If a partner withdraws, he continues refponfible for his former partners till it be publicly known that he hath done fo. A deed of feparation, regiftrated at a public office, is fufficient prefumption of fuch no¬ toriety. III. Companies, where the bufinefs is condufted by officers. There are many companies of this kind in Britain, chiefly eftablilhed for purpof-s which require a larger capital than private merchants can command. The laws with refpeft to thefe companies, when not ernfirmed by public authority, are the fame as the former, but the articles of their agreement ufually very different. The capital is condefcended on ; and divided into a certain number of lhares, whereof each partner may hold one or more', but is generally rellric- ted to a certain number. Any partner may transfer his lhare ; and the company mull admit his affignee as a partner. The dea h of the partners has no effeft on the company. No partner can aft perfonaliy in the affairs of the company : but the execution of their bu- finefs is intrnlled to officers, for whom they are refpon¬ fible ; and, when the partners are numerous, the fu- perintendency of the officers is committed to direftors chofen annually, or at other appointed times, by the partners. IV. Companies incorporated by authority. A royal charter is neceffary to enable a company to hold lands, to have a common feal, and enjoy the other privileges of a corporation. A charter is fometimes procu¬ red, in order to limit the rifk of the partners: for, in every private company, the partners are liable for PAR [ 5894 } PAR Partridge, the debts, without limitation ; in corporated focieties, they are only liable for their (hares in the ftock of the fociety. The incorporation of focieties is fometimes authorifed by a& of parliament; but this high autho¬ rity is not necefiary, unlefs for conferring exclufive privileges. PARTRIDGE, in ornithology. See Tetrao. The partridge is fo valuable at the table, that a great many ways of taking it have been invented by fportfmen, all of which fucceed from the natural folly and timidity of the animal. The places partridges delight in moft are corn-fields, e- fpecially whilft the corn grows, for underthat cover they flicker and breed : neither are thofe places unfrequent¬ ed by them when the corn is cut down, by reafon of the grain they find there, efpecially in wheat-ftubble, the height of which they delight in, being to them as a covert or (helter. When the wheat-ftubble is much trodden by men or beads, they then betake chem- felves to the barley-ftubble, provided it be frefh and untrodden; and they will, in the furrows, amongftthe clots, branches, and long grafs, hide both themfelves and coveys, which are fometimes 20 in number; nay, 30 in a covey. When the winter-feafon is arrived, and the ftubble- fields are ploughed up, or over-foiled with cattle, par¬ tridges refort into the upland meadows, and lodge in the dead-grafs, or fog under hedges, amongft mole¬ hills, or under the roots of trees; fometimes they refort to coppices and under-woods, efpecially if any corn-fields are adjacent, or where there is grown broom, brakes, fern, &c. In the harveft-time, when every field is full of men and cattle, in the day-time they are found in the fallow-fields which are next adjoining to the corn¬ fields, where they lie lurking till evening or morn¬ ing, and then they feed among the (heaves of corn. When their haunts are known, according to the fi- tuation of the country and feafon of the year, the next care muft be to find them out in their haunts, which is done feveral ways. Some do it by the eye only ; and this art can never be taught, but learned by frequent experience, the colour of the birds being fo like that of the earth at a diftance, that no eye but a very converfant one could diftinguilh them. Wh.m they arc once feen, the bufinefs is to keep the eye up¬ on them, and then to keep in continual motion. They are a very lazy bird, and by this means will let a per- fon almoft tread upon them ; though if the perfon (lands ftill to eye them, they will rife immediately, » though they be at a confiderable diftance. Another method of difcovering them, is by going to their haunts very early in the morning, or at the clofe of the evening, which is called the jucking- time. The noife of the cock-partride is to be attend¬ ed to at this time, and is very loud and earned. The hen will foon come up to the cock after her making the noife, which (he does by way of anfwer; and when they are got together, their chattering will difcover them. Thus they may always be found at thefe times. But there is a yet better method of finding this bird, which is by the call. The bufinefs, in order to have fuccefs in this way, is carefully to learn the notes of the partridge, and be able to imitate all the feveral founds. When perfed in this,, the perfon is to go to the haunts morning and evening, and placing himfelf Partridge in fome place where he can fee the birds without being !l feen by them, he is to liften to their calling ; and when Party' they are heard, he is to anfwer in the fame notes, doubling again as they do : by continuing this, they may be brought fo near, that the perfon lying down on his back may count their whole number. Having in this manner found where the birds are, the next care is to catch them. They are fo foolifh, that it is extremely eafy to take them in nets. In order to this, there needs no more than the going out, provided with two or three nets, with mtflies fomewhat fmaller than thofe of the phea- fant nets, and walking round about the covey, a net is to be fixed fo as to draw over them, on pulling a line at a diftance. All this may be eafily done ; for fo long as the fportfman continues moving about, and does not fix his eye too intenfely upon them, they will let him come near enough to fix the net, without moving. If they lie fo draggling, that one net will not cover them, then two or three muft be fixed in the fame manner. The fportfman may then draw the nets over them, and they will often lie ftill with the nets upon them till he comes up to fright them; then they will rife, and be entangled in the net. A fccond method of taking them is with bird-lime. this is done by means of wheat-draws. Thefe muft be large, and cut off between knot and knot; they muft be well lined with the bed and ftrongeft bird¬ lime, and the fportmen mud carry a great number out with him. Having found a field where there are par¬ tridges, he is to call; and if they anfwer, he is then to (tick up the limed draws in rows acrofs two or three lands, and going backward, call again to them, leading them on in the road where the draws are : they will follow one another like a flock of chickens, and come out to the call ; and will in their way run upon the draws, and liming themfelves they will daub one another by crowding together, fo that very few of them will be able to efcape. But there is yet a pleafanter way of taking them than this, that is, by driving of them. In order to this, an engine is to be made of canvas (luffed with draw, to reprefent a horfe ; this horfe and nets are to be taken to the haunts of the partridges, and the nets being placed flanting or flopewife in the lower part of the field, the fportfman is to take the wind in his back and get above them, driving them downwards; his face is to be covered with fomething green or blue, and placing the horfe before him, he is to go towards them (lowly and gently ; and by this means they will be raifed on their legs, bnt not on their wings, and will run before the horfe into the nets. If in the way they go into a wrong path, the horfe is to be moved to face them ; and they will be thus driven back again, and driven every way the fportfman pleafes. PARTURITION, the art of bringing forth, or being delivered of, young. See Midwifery. PARTY, in a military fenfe, a fmall number of men, horfe, or foot, fent upon any kind of duty; as into an enemy’s country to pillage, to take prifoners, and to oblige the country to come under contribution. Parties are often fent out to view the roads and ways, get intelligence, feek forage; to reconnoitre, or amufe the enemy upon a march : they are alfo frequently fent upon Parulides, Parus. PAR [ 5895 ] PAS upon the flanlcs of an army or regiment, to difcover the enemy if near, and prevent furprife or ambufcade. PARULIDES, in furgery, tumours and inflamma¬ tions of the gums, commonly called gum-boils. They are to be treated with difcutients like other inflamma¬ tory tumours. PARUS, or Titmouse, in ornithology, a genus belonging to the order of pafleres. The bill is very entire, covered at the bafis with hairs; the tongue is truncated and hairy. There are 14 fpecies ; of which the moft remarkable are, 1. The criftatus, or crefted titmoufe, weighs 13 pennyweight; the bill is black, with a fpot of the fame colour above it; all the upper part of the body gray ; the neck and under parts are white, with a faint tinfture of red, which is deepeft juft below the wings. The legs are of a lead colour. It eredfs its crown fea¬ thers into a creft. It inhabits the warm parts of Nort h America; and frequents.foreft-trees, feeding upon in¬ fers. 2. The major, or great titmoufe, has the head and throat black, the cheeks white, the back of a green colour, the belly yellowifh green, divided in the middle by a bed of black which extends to the vent; the rump of a bluifh grey, the legs of a lead colour, the toes divided to the very origin, and the back-toe very large and ftrong. This fpecies fometimes vifits our gardens ; but for the moft part inhabits woods, where it builds in hollow trees, laying about ten eggs. It feeds on infedts, which it finds in the bark of trees. In the fpring they do a great deal of mifchief by pick¬ ing off the tender buds of the fruit-trees. Like wood¬ peckers, they are perpetually running up and down the bodies of trees in queft of food. This bird has three cheerful notes, which it begins to utter in the month of February. 3. The cceruleus, or blue titmoufe, is a very beauti¬ ful bird. The bill is Ihort and dulky; the crown of the head of a fine blue ; from the bill to the eyes is a black line; the forehead and cheeks white; the back, of a yellowifh green; the lower fide of the body yel¬ low ; the wings and tail blue, the former marked tranfverfely with a white bar; the legs of a lead co¬ lour. They frequent gardens; and do great injury to fruit-trees, by bruifing the tender buds in fearch of the infers which lie under them. It breeds in holes of walls, and lays 12 or 14 eggs. 4. The virginianus, or yellow rump, is found in Vir¬ ginia ; and is diftinguifhed by a yellow fpot on its rump. All the reft of the feathers are brown, with . a flight tinfture of green. It runs about the bodies of trees; and feeds on infefts, which it pecks from the crevices of the bark. 3. The caudatus, or long-tailed titmoufe, is about five inches and a. quarter in length, and feven inches in breadth. The bill is black, very thick and convex, differing from all others of this genus. The top of the head, from the bill to the hind part, is white, mix¬ ed with a few dark-grey feathers: this bed of white is entirely furrounded with a broad ftroke of black ; which rifing on each fide of the upper mandible, paf- fes over each eye, unites at the hind part of the head, and continues along the middle of the back to the rump. The feathers on each fide of this black ftroke are of a purplifli red, as are thofe immediately incum- Vol. VIII. 2 bent on the tail. The tail is the longeft, in propor¬ tion to the bulk, of any Britifti bird, being in length three inches, the form not unlike that of a magpie, confiding of i2 feathers of unequal lengths, the mid- dlemoft the longeft, thofe on each fide growing gra¬ dually fhorter. Thefe birds are often feen paffing through our gardens, going from one tree to another, as if in their road to fome other place, never making any halt. They make their nefts with great elegance, of an oval fhape, and about eight inches deep, having near the upper .end a hole for admifiion. The exter¬ nal materials are moffes and lichens curioufly interwo¬ ven with wool. On the infide it is very warmly lined with a thick bed of feathers. The female lays from 10 to 17 eggs. The young follow their parents the whole winter ; and, from the flimnefs of their bodies, and great length of tail, appear, while flying, like as many darts cutting the air. 6. The biarmicus, or bearded titmoufe, has a fliort, ftrong, and very convex bill, of a box colour ; the head of a fine grey ; the chin and throat white ; the middle of the bread flefli-coloured ; the fides and thighs of a pale orange ; the hind part of the neck and back of" orange bay ; the tail is two inches and three quarters long ; the legs of a deep ftiining black. The fe¬ male wants the flrih-colour on the bread, and a trian¬ gular tuft of black feathers on each fide the bill which adorn the male. They are found in marfhy places. PASCAL (Blaise), one of the greateft geuiufea and bed writers France has produced, was born at Clermont in Auvergne, in the year 1623. His fa¬ ther, Stephen Pafcal, born in 1588, and of an ancient family, was pfefident of the court of aids in his pro¬ vince : he was a very learned man, an able mathema¬ tician, and a friend of Des Cartes. Having an ex¬ traordinary tendernefs for this child, his only fon, he quitted his office in his province, and went and fettled at Paris in 1631, that he might be quite at leifure for the inftru&ion of him ; and Blaife never had any ma¬ iler but his father. From his infancy he gave proofs of a very extraordinary capacity: for he defired to know the reafon of every thing ; and when good reafons were not given him, he would feek for better ; nor would he ever yield his affent but upon fuch as appeared to him well grounded. There was room to fear, that with fuch a call oFmind he would fall into free think¬ ing, or at leaft into heterodoxy ; yet he was always very far from any thing of this nature. What is told of his manner of learning the mathe¬ matics, as well as the progrefs he quickly made in that fcience, feems almoft miraculous. His father, percei¬ ving in him an extraordinary inclination to reafoning, was afraid left the knowledge of the mathematics would hinder his learning the languages. He kept him therefore as much as he could from all notions of geometry, locked up all his books of that kind, and refrained even from fpeaking of it in his prefence. He could not, however, make his fon refrain from milling upon proportions; and one day furprifed him at work with charcoal upon his chamber-floor, and in the midll of figures. He allied him what he was doing ? I am fearching, fays Pafcal, for fuch a thing ; which was juft the 32ft propofition of the firft book of Euclid. He alked him then how he came to think of this ? It was, fays Pafcal, becaufe I have found out fuch 33 G another Pifeai PAS [ 5896 ] PAS Pafcal. another thing : and fo going backward, and ufing the 'names of Errand round, he came at length to the de¬ finitions and axioms he had formed to himfelf. Does it not feem rr.i: aculous, that a boy fhould work his way into the heart of a mathematical book, without ever having feen that or any other book upon the fuhjeft, or knowing any thing of the terms? Yet we are af- fured of the truth of this by Madam Per'er, and fcve- ral other writers, the credit of whofe teftimony can¬ not reafbnably be queftioned. He had, from hence¬ forward, full liberty to indulge his genius in mathe¬ matical purfuits. He underllood Euclid’s Elements as foon as he cail his eyes upon them : and this was not tlrange ; for, as we have feen, he underftood them before. At 16 years of age he wrote a treatife of co¬ nic fefiions, which was accounted by the moll learned a mighty effort of genius ; and therefore it is no won¬ der that Des Cartes, who had been in Holland a long time, (hould, upon reading it, choofe to believe, that Mr Pafcal, the father, wTas the real author of it. At nineteen, he contrived an admirable arithmetical ma¬ chine, which was efteemed a very umnderful thing : and at twenty-three, having feen the Torricellian ex¬ periment, he invented and tried a great number of other new experiments. After he had laboured abundantly in mathematical and philofophical difquifitions, he forfook thofe ftudies and a!Khuman learning at once; and determined to know nothing, as it were, for the future, but Jefus Chrift and him crucified. He was not 24 years of age, when the reading fom-e pious books had put him upon taking this holy refolution; and be became as great a devotee as any age has produced. Mr Pafcal now gave himfelf up entirely to a ftate of prayer and mortification. He had always in his thoughts thefe great maxims, of renouncing all pleafure and all fuper- fluity; and this he pra&ifed with rigour even in his illneffes, to which he was frequently fubjeft, being of a very invalid habit of body: for inftance, when his ficknefs obliged him to feed fomewhat delicately, he took great care not to relifh or tafte what he eat. He had no violent affedlion for thofe he loved ; he thought it finful, fince a man pofftfies a heart which belongs only to God. He found fault with fome dif- courfes of his filler, which {be thought very innocent; as if (he had faid upon occafion, that fiie had feen a beautiful woman, he would be angry, and tell her, that /he might raife bad thoughts in footmen and young people. He frequently wore an iron girdle full of pojnts next to his {kin ; and when any va n thought came into his head, or when he took particular plea¬ fure in any thing, he gave himfelf fome blows with his elbow, to redouble the prickings, and to recall him¬ felf to his duty. Though Mr Pafcal had thus abftrafled himfelf from the world, yet he could not forbear paying fome at¬ tention to what was doing in it; and he even intereft- ed himfelf in the conteft: between the Jefuits and the Janfeniils. The Jefuits, though they had the popes and kings on their fide, were yet decried by the peo¬ ple,, who brought up afrefh againftthem the afiaffina- tion of Henry the Great, and all the old (lories that were likely to make them odious. Pafcal went far¬ ther ; and by his Lettres Provincialcs, publiftied in 1656, under the name of Louis de Montallt, made them the fubje£l of ridicule. “ Thefe letters,” fays Vol- Pafc! taire, “ may be confidered as a model of eloquence ^ and humour. The bed comedies of Moliere have not d qtl more wit than the firft part of thefe letters ; and the fublimity of the latter part of them is equal to any thing in Boffuet. It is true, indeed, that the whole book was built upon a falfe foundation ; for the extra¬ vagant- notions of a few Spanifh and Flemifh Jefuits were artfully aferibed to the whole fociety. Many ab- furdities might likewife have been difeovered among the Dominican and Francifcan cafuifts: but this would not have anfwered the purpofe; for the whole raillery was to be levelled only at the Jefuits. Thefe letters were intended to prove, that the Jefuits had formed a defign to corrupt mankind ; a defign which no fed or fociety ever had, or can have ” Voltaire, calls Pafcal the firft of their fatyrifts; for Defpreaux, fays h-e; muft be confidered as only the fecond. In another place, fpeaking of this work' of Pafcal, he fays, that “ examples of all the various fpecies of eloquence are to be found in it. Though it has been now written almoft too years, yet not a fingle word occurs in it, favouring of that viciffitnde to which living languages are fo fubjedt. Here then we are to fix the epocha when our language may he faid to have affumed a fet¬ tled form. The bifliop of Lncon, fon of the celebra¬ ted Bufly, told me, that alking one day the biftiop of Meaux what work he would covet moll to be the au¬ thor of, fuppofing his own perfftrmances fet afide, Bofiuet replied, The Provincial Letters.” Thefe let¬ ters have been tranflated into all languages, and print¬ ed over and over again. Some have faid, that there wgre decrees of formal condemnation againfl them ; and alfo that Pafcal himfelf, in his laft illnefs, detefted them, and repented of having been a Janfenift : but both thefe particulars are faife and without foundation. Father Daniel was fuppofed to be the anonymous au¬ thor of a piece againlt them, intitled, The Dialogues of Oleander and Eudoxus. Mr Pafcal died at Paris the 19th of Auguft 1662, aged 39 years. He had been fome time about a work againll atheifts and infidels, but did not live long enough to digeft the materials he had colleded. What was found among his papers was publdhed under the title of Pepjees, &c. or Thoughts upon religion and o~ ther fubjeSis, and has been much admired. After his death appeared alfo two other little trads ; one of _which is intitled, The equilibrium of fluids ; and the other, The weight ofthe mafs of air. To conclude, Mr Pafcal was, all things confidered, a man of a moft fingular compbfition ; or, as Mr Bayle fays, “ a parodoxical individuum of the human kind.” PASCHAL, fomething belonging to the paflbver, or Eafter.

PASQUIN, a mutilated (latute at Rome, in a corner of the palace of the Urfini.

Since that time all fatires are attributed to that figure; and are either put into its mouth, pr palled upon it, as if they were written by Pafquin redivivus; and thefe are addreffed by Pafquin to Mar- forio, another flatue at Rome.

Passions and Emotions, difference between them. See Emotions and Paffions. External Signs of Etnotions and Passions. So inti¬ mately connedled are the foul and body, that every agitation in the former produces a vifible effedt up¬ on the latter. There is, at the fame time, a wonder¬ ful uniformity in that operation ; each clafs of emotions and paffions being invariably attended with an ex¬ ternal appearance peculiar to itfelf. Thefe external appearances, or figns, may not improperly be confi- dered as a natural language, expreffing to all be¬ holders emotions and paffions as they arife in the heart. Hope, fear, joy, grief, are difplayed exter¬ nally : the charadler of a man can be read in his face ; and beauty, which makes fo deep an impreflion, is known to refult, not fo much from regular features and a fine complexion, as from good-nature, good- fenfe, fprightlinefs, fweetnefs, or other mental qua¬ lity, exprtffcd upon the countenance. Though per- fedl fkill in that language be rare, yet what is gene¬ rally known is fufficient for the ordicary purpofes of life. But by what means we come to underftand the language, is a point of fome intricacy. It cannot te by fight merely ; for upon the meft attentive infpec- tion of the human vifage, all that can be difeerned are figure, colour, and motion, which, fingly or com¬ bined, never can reprefent a paffion, nor a fentiment ; the external lign is indeed viffible ; but to underftand its meaning, we muft be able to ccnnedl it with the the paffion that caufes it, an operation far beyond the reach of eye-fight. Where then is. the inflrudlor to be found that can unveil this fecret connexion? If we apply to experience, it is yielded, that from long and diligent obfervation, we may gather, in fome meafure, in what manner thofe we are acquainted with exprefs their paffions externally : but with refpedt to ftrangers, we are left in the dark,; and yet we are not '33 G 2 puzzled [ 5897 ] Pa Herat I Pa (lions. PAS [ 5898 ] PAS Paffions. puzzled about the meaning of thefe external expref- "fions in a ftranger, more than in a bofom-companion. Further, had we no other means but experience for underftanding the external figns of paflion, we could not expedt any uniformity nor any degree of flcill in the bulk of individuals: yet matters are fo much bet¬ ter ordered, that the external expreffions of paffion form a language underftood by all, by the young as well as the old, by the ignorant as well as the learned: We talk of the plain and legible charadlers of that language; for undoubtedly we are much indebted to experience, in deciphering the dark and more delicate expreflions. Where then fhall we apply for a folution of this intricate problem, which feems to penetrate deep into human nature ? Undoubtedly if the mean¬ ing of external figns be not derived to us from fight, nor from experience, there is no remaining fource whence it can be derived but from nature. Elements of We may then venture to pronounce, with fome de- Criticifm. gree 0f confidence, that man is provided by nature with a fenfe or faculty that lays open to him every paffion by means of its external expreffions. And we cannot entertain any reafonable doubt of this, when we refleft,. that the meaning of external figns is not hid even from infants: an infant is remarkably affec¬ ted with the paffions of its nurfe exprefled on her countenance ; a finite chears it, a frown makes it afraid: but fear cannot be'without apprehending danger ; and what danger can the infant (apprehend, unlefs it be fenfible that its nurfe is angry ? We muft therefore admit, that a child can read anger in its nurfe’s face ; of which it muft be fenfible intuitively, for it has no other mean of knowledge. We do not affirm, that thefe particulars are clearly appre¬ hended by the child; for to produce clear and diflindl perceptions, reflection and experience are requifite: but that even an infant, when afraid, muft have fome notion of its being in danger, is evident. That we fhould be confcious intuitively of a paffion From its external expreffions, is conformable to the analogy of nature : the knowledge of that language is of too great importance to be left upon experience; becaufe a foundation fo uncertain and precarious, would prove a great obftacle to the formation of fo- cieties. Wifely therefore is it ordered, and agreeably to the fyftem of Providence, that we fhould have na¬ ture for our inftru&or. Manifold and admirable are the purpofes to which , the external figns of paffion are. made fubfervient by the Author of our nature. 1. The figns of internal agitation difplayed exter¬ nally to every fpe&ator, tend to fix the fignification of many words. The only effeftual means toafeertain the meaning of any doubtful word, is an appeal to the thing it reprefents : and hence the ambiguity of words expreffive of things that are not objefts of external fenfe; for in that cafe an appeal is denied. Paffion, ftri&jy fpeaking, is not an objeft of external fenfe: but its external figns are ; and by means of thefe figns, paffions may be appealed to with tolerable accuracy : thus the words that denote our paffions, next to thofe that denote external obje&s, have the moft dillinft meaning. Words fignifying internal aftion and the more delicate feelings, are lefs- diftin&. This defe& with regard to internal a&ion, is what chieily occa* fions the intricacy of logic: the terms of that fcience Paflions. are far from being fufficiemly afeertained, even after ~ much care and labour beftowed by an eminent writer*; * Locke. to whom however the world is greatly indebted, for removing a mountain of rubbifh, and moulding the fubjeft into a rational and corredt form. The fame de- feCt is remarkable in criticifnj, which has for its ob¬ ject the more delicate feelings ; the terms that denote thefe feelings being not more diftinCt than thofe of logic. z. Society among individuals is greatly promoted by that univerfal language. Looks and geftures give direCt accefs to the heart; and lead us to feleCt, with tolerable accuracy, the perfons who are worthy of our confidence. It is furprifing how quickly, and for the moft part how correCtly, we judge of character from external appearance. 3. After focial intercourfe is commenced, thefe ex¬ ternal figns, which diffufe through a whole afiembly the feelings of each individual, contribute above all other means to improve the focial' affeCtions. Lan¬ guage, no doubt, is the moft comprehenfive vehicle for communicating emotions: but in expedition, as well as in power of conviction, it falls (hort of the figns under confideration ; the involuntary figns efpecially, which are incapable of deceit. Where the counte¬ nance, the tones, the geftures, the aCtions, join with the words in communicating emotions, thefe united have a force irrefiftible : thus all the pleafant emo¬ tions of the human heart, with all the focial and vir¬ tuous affeCtions, are, by means of thefe external figns, not only perceived, but felt. By this admirable con¬ trivance, converfation becomes that lively and ani¬ mating amufement, without which life would at belt be intipid : one joyful countenance fpreads chearful- nefs inftantaneoufly through a multitude of fpeCtators. . 4. Diffocial paffions, being hurtful by prompting violence and mifehief, are noted by the moft confpi- cuous external figns, in order to put us upon our guard: thus anger and revenge, efpecially when fud- den, difplay themfelves on the countenance in legible character. The external figns, again, of every paffion that threatens danger, raife in us the paffion of fear: which frequently operating without reafon or reflection, moves us by a fudden impulfe to avoid the impending danger. 5. Thefe external figns are remarkably fubfervient to morality. A painful paffion, being accompained with difagreeable external figns, muft produce in every fpeCtator a painful emotion : but then, if the paffion be focial, the emotion it pruduces is attractive, and con- neCts the fpeCtator with the perfon who fuffers. Dif¬ focial paffions only, are productive of repulfive emo¬ tions, involving the fpeCtator’s averfion, and frequently his indignation. This artful contrivance makes us cling to the virtuous, and abhor the wicked. 6. Of all the external figns of paffion, thofe of af¬ fliction or diltrefs are the moft illuftrious with refpeft to a final caufe, and dtfervedly merit a place of di- ftinCtion. They are illuftrious by the Angularity of their contrivance ; and alfo by infpiring fympathy, a paffion to which human fociety is indebted for its greateft bleffing, that of providing relief for the di- ftrefled. A fubjeCt fo interefting, deferves a leifurely and attentive examination. The conformity of the na¬ ture PAS [ 5899 ] PAS Paffions. ture of man to his external circumftances, is in every ' particular wonderful: his nature makes him prone to fociety ; and fociety is neceffary to his well-being,-be- caufe in a folitary ftate he is a helpltfs being, defti- tute of fupport, and in his diftreffes dellitute of re¬ lief : but mental fupport, the Ihining attribute of fociety, is of too great moment to be left depen¬ dent upon cool reafon ; it is ordered more wifely, and with greater conformity to the analogy of nature, that it fhould be enforced even inftindively by the paffion offympathy. Here fympathy makes a capital figure ; and contributes, more than any other means, to make life eafy and comfortable. But however ef- fential the fympathy of others may be to our well¬ being, one beforehand would not readily conceive how it could be raifed by external figns of diftrefs: forcon- fidering the analogy of nature, if thefe figns be agree¬ able, they mud give birth to a pleafant emotion lead¬ ing every beholder to be pleafed with human woes: if difagreeable, as they undoubtedly are, ought they not naturally to repel the fpe&ator from them, in order to be relieved from pain ? Such would be the reafon- ing beforehand ; and fuch would be the effeft were man purely a felfifh being. But the benevolence of our nature gives a very different dire&ion to the pain¬ ful pafiion of fympathy, and to the defire involved in it: inflead of avoiding diftrefs, we fly to it in order to afford relief; and our fympathy cannot be other- wife gratified but by giving all the fuccour in our power. Thus external figns of diftrefs, though difa¬ greeable, are attraftive : and the fympathy they in- fpire is a powerful caufe, impelling us to afford re¬ lief even to a ftranger, as if he were our friend or re¬ lation. It is a noted obfervation, that the deepeft tragedies are the moft crowded: which in an overly view will be thought an unaccountable bias in human nature. Love of novelty, defire of occupation, beauty of a&ion, make us fond of theatrical reprefentations; and when once engaged, we muft follow the ftory to the conclufion, whatever diftrefs it may create. But we generally be¬ come wife by experience ; and when we forefee what pain we fhall fuffcr during the courfe of the reprefen- tation, is it not furprifing that perfons of refleftion do not avoid fuch fpeftacles altogether ? And yet one who has fcarce recovered from the diftrefs of a deep tragedy, refolves coolly and deliberately to go to the very next, without the flighted obftruftion from felf-love. The whole myftery is explained by a Angle fcbfervation : That fympathy, though painful, is attradlive; and at¬ taches us to an objeft in diftrefs, inftead of prompting us to fly from it. And by this curious mechanifm it is, that perfons of any degree of fenfibility are attrac¬ ted by afflidtion ftill more than by joy. To conclude: the external figns of paflion are a ftrong indication, that man, by his very conftitution, is fra¬ med to be open and fincere. A child, in all things obedient to the impulfes of nature, hides none of its emotions ; the favage and clown, who have no guide but pure nature, expofe their hearts to view, by giving way to all the natural figns. And even when men learo to difiemble their fentiments, and when behaviour de¬ generates into art, there ftill remain checks, that keep difixmulation within bounds, and prevent a great part of its mifchievous effedks: the total fuppreffion of the voluntary figns during any vivid paffion, begets the Paffieits. utmoft uneafinefs, which cannot be endured for any confiderable time : this operation becomes indeed lefs painful by habit; but luckily the involuntary figns cannot, by any effort, be fuppreffed nor even diffem- bled. An abfolute hypocrify, by which the chara&er is concealed and a fiftitious one afl’umed, is made im~ pradlicable; and nature has thereby prevented much harm to fociety. We may pronounce, therefore, that Nature, herfelf fincere and candid, intends that man¬ kind fhould preferve the fame charadler, by cultiva¬ ting fimplicity and truth, and banifbing every fort of diffimulation that tends to mifehief. Influence of Passion 'with refpett to our Perceptions, Opinions, and Belief. So intimately are our perceptions, paffions, and aftions, conne&ed, it would be won¬ derful if they fhould have no mutual influence. That our aftions are too much influenced by paffion, is a known truth ; but it is not lefs certain, though not fo well known, that paffion hath alfo an influence upon our perceptions, opinions, and belief. For example, the opinions we form of men and things are generally diredled by affedtion : An advice given by a man of fi¬ gure hath great weight ; the fame advice from one in a low condition is defpifed or neglefted : a man of courage under-rates danger; and to the indolent the flighteft obftacle appears unfurmountable. There is no truth more univerfally known, than Elements of that tranquillity and fedatenefs are the proper ftate 0fCriticifm, mind for accurate perception and cool deliberation ; ^c0c>'1'p'Ii3 and for that reafon, we never regard the opinion even of the wifeft man, when we difeover prejudice or paf¬ fion behind the curtain. Paffion hath fuch influence over us, as to give a falfe light to all its objefts. A- greeable paffions prepoffefs the mind in favour of their objefts; and difagreeable paffions, not lefs againft their objefts : A woman is all perfection in her lover’s opi¬ nion, while in the eye of a rival beauty fhe is aukward and difagreeable : when the paffion of love is gone, beauty vanifhes with it;—nothing left of that genteel motion, that fprightly converfation, thofe numberlefs graces, which fonnerly, in the lover’s opinion, charm¬ ed all hearts. To a zealot every one of his own fed is a faint, while the moft upright of a different fed are to him children of perdition : the talent of fpeak- ing in a friend, is more regarded than prudent condud in any other. Nor will this furprife any one acquaint¬ ed with the world ; our opinions, the refult frequently of various and complicated views, are commonly fo flight and wavering, as readily to be fufceptible of a bias from paffion. With that natural bias another circumftance con¬ curs, to give paffion an undue influence on our opi¬ nions and belief; and that is a ftrong tendency in our nature to juftify our paffions as well as our aftions, not to others only, but even to ourfelves. That ten¬ dency is peculiarly remarkable with refped to difa¬ greeable paffions: by its influence, objeds are magni¬ fied or leffened, circumftances fnpplied or fuppreffed, every thing coloured and difguifed, to anfwer the end of juftification. Hence the foundation of felf-deceit, where a man impofes upon himfelf innocently, and even without fufpicion of a bias. We proceed to illuftrate the foregoing ofcfervations by proper examples. Gratitude, PAS [ 5900 ] PAS •puSlonj. Gratitude, when warm, is often exerted upon the " children of the benefa&or ; efpecially where he is re* moved out of reach by death or abfence. The pafiion in this cafe being exerted for the fake of the benefac¬ tor, requires no peculiar excellence in his children : but the pra&ice of doing good to thefe children pro¬ duces affedion for them, which never fails to advance them in our efteem. By fuch means, ftrong connec¬ tions of affedion are often formed among individuals, upon the flight foundation now mentioned. Envy isa pafiion, which, beingaltogether unjuftifiable, cannot be excufed but by difguifing it under fome plau- lible name. At the fame time, no paflion is more eager than envy, to give its objed a difagreeable ap¬ pearance : it magnifies every bad quality, and fixes on the moll humbling circumffances : Cajjius. I cannot tell what you and other men Think of this life ; but for my fingle felf, I had as lief not be, as live to be In awe of fuch a thing as I myfelf. I was born free as Casfar, fo were you ; We both have fed as well; and we can both Endure the winter’s cold as well as he. Por once, upon a raw and gully day. The troubled Tyber chafing with his fliores, Casfar fays to me, Dar’ll thou, Caflius, now Leap in with me into this angry flood. And fwim to yonder point ?—Upon the word, Accoutred as I was, I plunged in, And bid him follow; fo indeed he did. The torrent roar’d, and we did buffet it With lufty finews ; throwing it afide, And Hemming it with hearts of controverfy. But ere we could arrive the point propos’d, Caefar cry’d, Help me, Caffius, or I fink. I, as iEneas, our great anceftor, Did from the flames of Troy upon his flioulder The old Anchifes bear ; fo from the waves of Tyber Did I the tired Caefar: and this man Is now become a god ; and Cafiius is A wretched creature, and mull bend his body If Caefar carelefdy but nod on him. He had a fever when he was in Spain ; And when the fit was on him, I did mark How he did lhake. ’Tis true, this god did {hake ; His coward lips did from their colour fly ; And that fame eye whofe bend doth awe the world. Did lofe its luftre ; I did hear him groan ; Ay, and that tongue of his, that bade the P.omans Mark him, and write his fpeeches in their books, Alas! it cry’d—Give me fome drink, Titinius,— As a lick girl. Ye gods, it doth amaze me, A man of fuch a feeble temper fliould So get the ftart of the majeilic world, And bear the palm alone. Julius Cafar, afl i.jfc. 3.

When by great fenfibility of heart, or other meads, grief becomes immoderate, the mind, in order toju- flify itfelf, is prone to magnify the caufe j and if the real caufe admit not of being magnified, the mind feeks Paflionj. a caufe for its grief in imagined future events: Bujby.

Yet I know no caufe Why I ffiould welcome fuch a gueft as grief; Save bidding farewell to fo fweet a gueft As my fweet Richard : yet again, methinks. Some unborn forrow, ripe in Fortune’s womb, Is coming tow’rd me : and my inward foul With fomething trembles, yet at nothing grieves. More than with parting from my lord the king. Richard II. all z. fc. 5. Refentment at firft is vented on the relations tof the offender, in order to punilh him : but as refentment, when fo outrageous, is contrary to confcience, the mind, to juftify its paflion, is difpofed to paint thefe relations in the blacked colours ; and it comes at laft to be convinced, that they ought to be punifhed for their own demerits. Anger raifed by an accidental ftroke upon a tender part of the body, is fometimes vented upon the un- defigning caufe. But as the pafiion in that cafe is ab- furd, and as there can be no folid gratification in pu- nilhing the innocent, the mind, prone to juftify as well as to gratify its pafiion, deludes itfelf into a convic¬ tion of the aftion’s being voluntary. The conviction, however, is but momentary ; the firft reflection fhows it to be erroneous: and the pafiion vanifheth almoft inftantaneoufly with the conviction. But anger, the mod violent of all pafiions, has ftill greater influence : it fometimes forces the mind to perfonify a flock or a done if it happen to occafion bodily pain, and even to believe it a voluntary agent, in order to be a proper objeCt of refentment. And that we have really a mo¬ mentary conviction of its being a voluntary agent, mud be evident from confidering, that without fuch conviction the pafiion can neither be juftified nor gra¬ tified : the imagination can give no aid ; for a flock or a ftone imagined fenfible, cannot be an objeCt of punifhment, if the mind be confcious that it is an ima¬ gination merely without any reality. Of fuch perfo- nification, involving a conviction of reality, there is one illuftrious inftance. When the firft bridge of boats over the Hrllefpont was deftroyed by a ftorm, Xerxes fell into a tranfport of rage, fo excefiive, that he com¬ manded the fea to be punilhed with 300 ftripes ; and a pair of fetters to be thrown into it, enjoining the following words to be pronounced : “ O thou fait and bitter water! thy mailer hath condemned thee to this punifhment for offending him without caufe ; and islib. 7. refolved to pafs over thee in defpight of thy infolence : with reafon all men negleCt to facrifice to thee, becaufe thou art both difagreeable and treacherous.” Shakefpeare exhibits beautiful examples of the ir¬ regular influence of pafiion in making us believe things to be otherwife than they are. King Lear, in his di- ftrefs, peifonifies the rain, wind, and thunder; and in order to juftify his refentment, believes them to be taking part with his daughters : Lear. Rumble thy bellyfull, fpit fire, fpout rain! Nor Pufliops. PAS [ 5901 ] PAS Paffions.

The power of paflion to falfify the computation of time is remarkable in this inftance ; becaufe time, which hath an accurate meafure, is lefs obfequious to our de' fires and wiihes, than objects which have no precife ftandard of lefs or more. Good news arc greedily fwallowed upon very (len¬ der evidence; our vvifttes magnify the probability of the event, as well as the veracity of the relater ; and we believe as certain, what at beft is doubtful: Quel, che 1’ huom vede, amor li fa invifibie L 1’invifibil fa vcder amore. Quefto creduto ft), che ’1 mifer fuo’e Dar facile credenza a’ quel, che vuole. Or land. Furiof. cant. I. Jl. 56. For the fame reafon, bad news gain alfo credit upon the flighted evidence : fear, if once alarmed, has the fame effedd with hope, to magnify every circumftance that tends to convidlion. Shakefpeare, who (hows more knowledge of human nature than any of our phi- lofophers, hath in his Cymbeline reprefented this bias of the mind ; for he makes the perfon who alone was affedled with the bad news, yield to evidence that did not convince any of his companions. And Othello is convinced of his wife’s infidelity from circumftances too flight to move any perfon lefs interefted. If the news intereft us in fo low a degree as to give place to reafon, the effedd will not be altogether the fame : judging of the probability or improbability of the (lory, the mind fettles in a rational conviddion ei¬ ther that it is true or not. But even in that cafe, the mind is not allowed to reft in that degree of convic¬ tion which is produced by rational evidence: if the news be in any degree favourable, our belief is raifed by hope to an improper height; and if unfavourable, by fear. This obferyation holds equally with refpedd to fu¬ ture events : if a future event be either much vviihed or dreaded, the mind never fails to augment the pro¬ bability beyond truth. That eaiinefs of belief with refpedd to wonders and prodigies, even the moft abfurd and ridiculous, is a (trange phenomenon ; becaufe nothing can be more evident than the following propolition, That the more Angular any event is, the more evidence is required to produce belief: a familiar event daily occurring, being in itfelf extremely probable, finds ready credit, and therefore is vouched by the flighted evidence ; but to overcome the improbability of a ftrange and rare event, contrary to the courfe of nature, the very ftrongeft evidence is required. It is certain, however, that wonders, and prodigies are fwailowed by the vulgar,, upon evidence that would not be fuificient to ascer¬ tain the moft familiar, occurrence. It has been rec¬ koned difficult to explain that irregular bias of mind ; but we are now made acquainted with the influence of paflion upon opinion and belief: a (lory of ghofts or fairies, told with an air of gravity and truth, raifeth an emotion of wonder, and perhaps of dread ; and thefe emotions impofing on a weak mind, imprefs upon it a thorough, convidion contrary to reafon. Opinion and" belief are influenced by propenfity as well as by paffion. Am innate propenfity is all we have' to convince us that the operations of nature are uni¬ form: influenced by that propenfity, we often raflily think, that good or bad weather will never have an end; and in natural philofophy, writers, influenced by the fame propenfity, ftretch commonly their ana¬ logical reafbnings beyond juft bounds. Opinion; PAS [ 5902 ] PAS Paffions. Opinion and belief are influenced by affettion as well as by propenfity. The noted ftory of a fine lady and a curate viewing the moon through a telefcope, is a pleafant illuftration : “ I perceive,” fays the lady, “ two fliadows inclining to each other ; they are cer¬ tainly two llappy lovers “ Not at all,” replies the curate, “ they are two fteeples of a cathedral.” Language 0/'Passion. Among the particulars that compofe the focial part of our nature, a propenfity to communicate our opinions, our emotions, and every , thing that affe&s us, is remarkable. Bad fortune and injuftice affeft us greatly ; and ofthefe we are fo prone to complain, that if we have no friend nor acquaint¬ ance to take part in our fufferings, we fometimes utter our complaints aloud, even where there are none to li- ften. But this propenfity operates not in every ftate of mind. A man immoderately grieved, feeks to afflift himfelf, rejefting all confolation : immoderate grief accordingly is mute ; complaining is struggling for confolation. It is the wretch’s comfort ftill to have Some fmall referve of near and inward wo, Some unfufpe&ed hoard of inward grief. Which they unfeen may wail, and weep, and mourn, And glutton-like alone devour. Mourning Bride, r. When grief fubfides, it then, and no fooner, finds a tongue : we complain, becaufe complaining is an ef¬ fort to difburden the mind of its diftrefs. This obfer- vation is finely illuftrated by a ftory which Herodotus records, b. 3. Cambyfes, when he conquered Egypt, made Pfammenitus the king prifoner; and for trying his conftancyr, ordered his daughter to be dreffed in the habit of a flave, and to be employ’d in bringing water from the river; his fon alfo was led to execution with a halter about his neck. The Egyptians vented their forrow in tears and lamentations: Pfammenitus only, with a downcaft eye, remained filent. Afterward meeting one of his companions, a man advanced in years, who, being plundered of all, was begging alms, he wept bitterly, calling him by his name. Cambyfes, ftruck with wonder, demanded an anfwcr to the fol¬ lowing queftion : “ Pfammenitus, thy mafter Camby¬ fes is defirous to know, why, after thou hadft feen thy daughter fo ignominiofly treated, and thy fon led to execution, without exclaiming or weeping, thou fhouldft be fo highly concerned for a poor man, no way rela¬ ted to thee ?” Pfammenitus returned the following anfwer: “ Son of Cyrus, the calamities of my family are too great to leave me the power of weeping; but the misfortunes of a companion, reduced in his old age to want of bread, is a fit fubjefl for lamentation.” Surprife and terror are filent paffions, for a different reafon : they agitate the mind fo violently, as for a time to fufpend the exercife of its faculties, and among others the faculty of fpeech. Love and revenge, when immoderate, are not more loquacious than immoderate grief. But when thefe paffions become moderate, they fet the tongue free, and, like moderate grief, become loquacious. Mode¬ rate love, when unfuccefsful, is vented in complaints when fuccefsful, is full of joy expreffed by words and geftures. As no paffion hath any long uninterrupted exiftence, Paffions, nor beats always with an equal pulfe, the language' fuggefted by paffion is not only unequal but frequent¬ ly interrupted : and even during an Uninterrupted fit of paffion, we only exprefs in words the more capital fentiments. In familiar converfation, one who vests every fingle thought, is juflly branded with the cha- ra&er of loquacity4 becaufe fenfible people exprefs no thoughts but what make fome figure : in the fame manner, we are only difpofed to exprefs the ftrongeft impulfes of paffion, efpecially when it returns with im- petuofity after interruption. It is elfewhere obferved *, that the fentiments ought * ?e.e ‘*!e to be tuned to the paffion, and the language to both.* Elevated fentiments require elevated language : tender fentiments ought to be clothed in words that are foft and flowing: when the mind is depreffed with any paffion, the fentiments muft be expreffed in words that are humble, not low. Words being intimately con- pe&ed with the ideas they reprefent, the greateft har¬ mony is required between them: to exprefs, for ex¬ ample, an humble fentiment in high-founding words, is difagreeable by a difcordant mixture of feelings; and the difcord is notlefs when elevated fentiments are dreffed in low whrds ; Verfibus exponi tragicis res comlca non vult. Indignatur item privatis ac prope focco Dignis carminibus narrari ccena Thyeflee. Herat. An poet. 1. 89. This, however, excludes not figurative expreffion, which, within moderate bounds, communicates to the fentiment an agreeable elevation. We are fenfible of an effedl direftly oppofite, where figurative expreffion is indulged beyond a juft meafure : the oppofition be¬ tween the expreffion and the fentiment makes the dif¬ cord appear greater than it is in reality. At the fame time, figures are not equally the lan¬ guage of every paffion : pleafant emotions, which ele¬ vate or fwell the mind, vent themfelves in ftrong epi¬ thets and figurative expreffion ; but humbling and dif- piriting paffions affedt to fpeak plain : Et tragicus plerumque dolet fermone pedeftri Telephus et Peleus: cum pauper et exul uterque ; Projicit ampullas et fefquipedalia verba. Si curat cor fpedlantis tetigeffe querela. Herat. Art poet. 95. Figurative expreffion, being the work of an enlivened imagination, cannot be the language of anguifti or di- ftrefs. Otway, fenfible of this, has painted a feene of diftrefs in colours finely adapted to the fubjedt : there is fcarce a figure in it, except a ffiort and natural fi- mile with which the fpeech is introduced. Belvidera talking to her father of her hufband : Think you faw what paft at our laft parting; Think you beheld him like a raging lion, Pacing the earth, and tearing up his fteps, Fate in his eyes, and roaring with the pain Of burning fury ; think you faw his one hand Fix’d on my throat, while the extended other Grafp’d a keen threat’ning dagger: oh, ’twas thus We laft embrac’d, when, trembling with revenge.

To preferve the forefaid refemblance between words and their meaning, the fentiments of active and hurry¬ ing pafiions ought to be dreffed in words where fyl- lables prevail that are pronounced (hort or fad ; for thefe make an impreffion of hurry and precipitation. Emotions, on the other hand,, that reft upon their objedfs, are beft expreifed by words where fyllables prevail that are pronounced long or flow. A perfon affedted with melancholy, has a languid and flow train of perceptions. Theexpreffion belt fuited to that ftate of mind, is where words, not only of long, but of many fyllables, abound in the compofition ; and for that reafon, nothing can be finer than the following paflage: In thofe deep folitudes, end awful cells, Where heav’nly-penfive Contemplation dwells, And ever-muling Melancholy reigns. Pope, Eloifa to Abelard. To preferve the fame refemblance, another circum- flance is requifite, that the language, like the emo¬ tion, be rough or fmooth, broken or uniform. Calm and fweet emotions are beft exprefled by words that glide foftly: furprife, fear, and other turbulent paf¬ iions, require an expreffion both rough and broken. It cannot ha=ve efcaped any diligent inquirer into na¬ ture, that in the hurry of paffion, one generally ex- preffes that thing firft which is moft at heart; which is beautifully done in the following paflage. Me, me; adfum qui feci: in me convertite ferrum, O Rutuli, mea fraus omnis. JEneid. ix. 427. Paffion has often the effe& of redoubling words, the better to make them exprefs the ftrong conception of the mind. This is finely imitated in the following examples. Thou fun, faid I, fair light!

Thefe foliloqnies are accurate and bold copies of na¬ ture: in a paffionate foliloquy one begins with think¬ ing aloud ; and the ftrongeft feelings only, are ex- prtiled ; as the fpeaker warms, he begins to irragine one liftening, and gradually Aides into a connedled dif¬ eourfe. How far diftant are foliloquies generally from thefe models? So far indeed as to give difguft inftead of pleafure.

Nothing can be more ridiculous s it puts one in mind of a moft curious device in Gothic paintings, that of making every figure explain itfelf by a written label iffuing from its mouth. The defcription which a pa- rafite, in the eunuch of Terence (aft z. fc. 2.) gives of himfelf, makes a fprightly foliloquy : but it is not confiftent with the rules of propriety ; for no man, in his ordinary (late of mind and upon a familiar fubjedl, ever thinks of talking aloud to himfelf. The fame ob- je&ion lies againft a,foliloquy in the Adelphi of the fame author, (aft \. fc. i.) The foliloquy which makes the third fcene a& third of his Heicyra, is in- fufferable ; for there Pamphilus, foberly and circum- ftantially, relates to himfelf an adventure which had happened to him a moment before. Corneille is unhappy in his foliloquies : Take for a fpecimen the firft fcene of Cinna. Racine is extremely faulty in the fame refpeif. His foliloquies are regular harangues, a chain completed in every link, without interruption or interval: that of Antiochus in Berenice (aft r. fc. 2.) refembles a re¬ gular pleading, where the parties pro and con difplay their argHments at full length.

Passions, in Medicine, make one of the non¬ naturals, and produce very fenfible effedls. Joy, an¬ ger, and fear, are the principal. In the two firft, the fpirits are hurried with too great vivacity ; whereas, in fear or dread, they are as it were curbed and con¬ centrated : whence we may conclude, that they have a very bad effeft upon health; and therefore it will be beft to keep them within bounds as much as pofiible, and to preferve an inward ferenity, cahnnefs, and tran¬ quillity. Passions, in Painting, are the external exprefiions of the different difpofitions and affedions of the mind; but particularly their different effefts upon the feveral features of the face : for though the arms, and indeed every part of the body*, ferve likewife, by their * See Ora- quick, languid, and varioufly diverfified motions, to/ exprefs the pafliotns of the foul; yet, in painting, tins'5*5’ difference is moft confpicuous in the face. See Paint¬ ing, n° 15. and Drawing, art. 9. In forrow, joy, love, lhame, and compaffion, the eyes fwell all of a fudden, are covered with a fupera- bundant moifture, and drop tears ; and, in grief efpe- cially, the corners of the mouth hang down, the eye¬ lids are half Unit, and the pupil of the eye is elevated and half covered ; and all the other mufcles of the face are relaxed, fo that the vifage appears longer than or¬ dinary. < 2 33 H 2 In [ 59°J 1 PAT [ 5906 ] PAT PalHon In fear, terror, fright, and horror, the eye-brows ^ I are greatly elevated: the eye-lids are expanded as a |,Qrt‘ wide as poffible, fo as to difeover the white of the eye ; and the pupil is depreffed, and half covered by the lower eye-lid : the hair ftands on ettd : the mouth • is at the fame time wide open ; and the lips are fo far drawn back, that the teeth both of the upper and under jaw appear.

PASSIVE, in general, denotes fomething that fuf- fers the a&ion of another, called an age?it or aftive power. In grammar, the verb or word that expreffes this palfion is termed z pajjive verb: which, in the learned languages, has a peculiar termination ; as amor, doceor, &c. in Latin ; that is, an r is added to the a£lives doceo; and, in the Greek, the inflec¬ tion is made by changing « into o,«s« ; as rurfo tv*1q- &c. But, in the modern languages, the paffive inflexion is performed by means of auxiliary verbs, joined to the participle paffive ; as, “ I am praifed,” in Latin laudor, and in Greek iTr*mov.ai; or, “ I am loved,” in Latin amor, and in Greek pixso^cu. Thus it appears, that the auxiliary verb I ayn, ferves to form the paffives of Engfifh verbs: and the fame holds of the French; as, J-e fms loue, '* I am prai- fed j’aiete hue, “ I have been praifed,” &c. Passive Tit/e, in Scots law. See Law, Part III. N° clxxx. 30. PASSOVER, a folemn feftival of the Jews, cele¬ brated on the 14th day of the month next after the vernal equinox, and inftituted in commemoration of their coming out of Egypt; becaufe, on the night before their departure, the deftrerying angel, who put to death the firft-born of the Egyptians, palled over the houfes of the Hebrews, which were fprinkled with the blood of a lamb.

PASSPORT, or Pass, a licence or writing ob¬ tained from a prince or governor, granting permiffion and a fafe-conduft to pafs through his territories with¬ out moleftation. Alfo a permiffion granted by any ftate to navigate in fome particular fea, without hin¬ drance or moleftation from it.

PASTINACA, the Parsnep, in botany, a genus of the digynia order, belonging to the pentandria clafs of plants. There are only iwo fpecies of this genus; the principal of which is the pajlinaca fativa, or garden-parfnep : which is an exceeding fine efculent root. It is to be propagated by fawing the feeds in February or March, in a rich mellow foil,, which mult be deep dug, that the roots may be able to run deep without hindrance. It is a common practice to fow carrots at the fame time, upon the fame ground with the parfneps; and if the carrots are defigned to be drawn young, there is no harm in it. The parfneps, when they are grown up a little, mull be thinned to a foot diftance, and carefully kept clear of weeds. They are finett tatted juft at the feafon when the leaves are decayed ; and fuch as are defirous to eat them in fpring ffiould have them taken up in autumn, and preferved in fand. ,When the feeds are to be faved, fome very ftrong and fine plants Ihould be left four feet diftance ; and to¬ wards the end of Auguft, or in the beginning of Sep¬ tember, the feeds will be ripe: they muft then be carefully gathered, and dried on a coarfe cloth.

Dr Cullen obferves, that pafte is very hard and in- digettible without butter; and, even with it, is apt to produce heart-burn and acefceney. Perhaps this is increafed by the burned butter, from a certain fenfitri- lity in the ftoroaeh, which oecafions all empyreumatic oils to be long retained, and fo turn rancefcent and acid. PAS rLTRE, or Px%TVKU-Land, is that referred for feeding cattle. Pafture-land is of fuch advantage to hufbandry, that many prefer it even to corn-land, becaufe of the fmall hazard and labour that attends it; and as it lays the foundation for moft of the profit that is expedled from, the arable land, becaufe of the manure afforded by the cattle which are fed upon it.

PATAGONIA, a country of Sonth America, com¬ prehending all that country extending from Chili and Paraguay to the ntmoft extremity of South America; that is, from 350 ahnoft to 54.0 of latitude: being fur- rounded by the countries jutt mentioned, the South and North Seas, and the Straits of Magellan, which fepa- rate it from the ifland called Terra del Fuego, and ex¬ tend about 116 leagues in length from fea to fea, but only from half a league to three or four in breadth. This country had the name of Terra Magellanka, from Ferdinand Magellan, a Portuguefe officer in the fervice of the Catholic king, who is reported to have failed through the (traits that alfo bear his name, from the North to the Sonth Sea, in the year 1510. The lofty mountains of the Andes, which are co¬ vered with fnowa great part of the year, traverfing the country from north to fouth, the air is faid to be much colder than in the north under the fame parallels of latitude. Towards the north, it is faid to be covered with wood, and ttored with an inexhanftible fund of large timber; whereas, to the fouthward, not fo much as a fingle tree fit for any mechanical purpofe is to be feen: yet there is good pafture, and incredible numbers of wild horned cattle and horfes, which were firft brought hither by the Spaniards, and have increafed amazingly. Freffi water, we are told by feme writers, is very fcarce ; but if that were really the cafe, it is dif¬ ficult to conceive how the prefent inhabitants, and fuch multitudes of cattle, could fubfift. The eaft coaft is moftly low land, with few or no good harbours: one of the beft is Port St Julian. Patagonia is inhabited by a variety of Indian tribes; as the Patagons, from which the country takes its name; the Pampas, the Coffares, &c. of whom we know very little. Only it appears, from the accounts of former voyagers, lately confirmed by commodore Byron and his crew, and the tellimonies of other navigators, that fome of them are of a gigantic ftature, and clo¬ thed with fkins; but it would feetn that there are o- thers who go almoft quite naked, notwithftanding the inclemency of the climate. Some of them alfo, that live about the Straits, if we may credit the navigators who have paffed that way into the South Sea, are per- fe& favages: but thofe with whom commodore Byron and his people converfed, are reprefented as of a more gentle humane difpofition; only, like other favages, they live on fi(h and game, and what the earth produces fpontaneoufly. The Spaniards once built a fort upon the Straits, and left a garrifon in it, to prevent any other Euro¬ pean nation paffing that way into the South Sea: but motl' of the men periffied by famine, whence the place obtained the name of Port Famine; and no people have attempted to plant colonies here ever fince. About the middle of the Strait is a promontory call¬ ed Cape Froifard, which is the mod foutherly on the Continent of South America. On the coafts of Patagonia lie a great number of iflands, or clufters of iflands. On the weft coaft are the iflands Madre de Dios, Santa Trinidad, Santa Cruz, the ifles of the Chunians and Huillans, the Sarmientos, and many others; to the number of 80 in all, as fome fay. Of thofe on the fouth coaft, the moft confider- Patan able are Terra del Fuego, and Staten Land* Ste thefe II articles. *>atenC' PATAN, a kingdom of Afia, in the Eaft Indies, and in the peninfula of Malacca, and on the eaftern coaft between the kingdoms of Siam and Paha. The inhabitants are partly Mahometans and partly Gentoos; but they are all very voluptuous. The air is wholefome, though very hot; and they have no feafons but the winter and fummer. The former is more properly the rainy feafon ; and contains the months of November, December, and January. The woods are full of ele¬ phants and many wild animals. Some voyagers pre¬ tend that this country is governed by a queen, who ne¬ ver marries, but may have as many gallants as (he pleafes. They have fome trade with theChinefe; and the principal town is of the fame name, which is one of the ftrongeft in thefe parts, having a well defended habour.

PATER patratus, in Roman antiquity, an offi¬ cer chofen by one of the college of feciales out of their own body, to treat with an enemy on the fubjeft of war and peace. He derived his title from a circum- ilance necefiary to his enjoying it: for in order that he might be the more firmly interefted in the fate of his country, he was to have both a father and a fon living at the fame time. PATERA, among antiquaries, a goblet or vefiel ufed by the Romans in their facrifices ; wherein they offered their confecrated meats to the gods, and where¬ with they made libations. See Sacrifice and Liba¬ tion. * The word is Latin, formed from pateo, “ I am o- pen;” quodpateat, “ becaufe it has a great aperture;” in contraditiinftion to bottles, &c. which have only narrow necks, or whofe aperture is lefs than the body of the veffef. On medals the patera is feen in the hands of feveral deities ; and frequently in the hands of princes, to mark the facerdotal authority joined with the imperial, &c. Hence F. Joubert obferves, that befide the patera, there is frequently an altar upon which the patera feems to be pouring its contents. The patera was of gold, filver, marble, brafs, glafs, or earth ; and they ufed to inclofe it in urns with the alhes of the deceafed, after it had ferved for the liba¬ tions of the wine and liquors at the funeral. The patera is an ornament in archite&ure, frequently feen in the Doric freeze, and the tympans of arches. PATERCULUS‘(Caius Velleius), an ancient Ro¬ man hiitorian, who fiourifhed in the reign of Tiberius Csefar, was born in the year of Rome 735. His ance- ftors were illuftrious for their merit and their offi¬ ces. His grandfather efpoufed the party of Tibe¬ rius Nero, the emperor’s father; but being old and infirm, and not able to accompany Nero when he retired from Naples, he ran himfelf through with his fword. His father was a foldier of rank, and fo was Paterculus himfelf. He was a' military tribune when Cains Caefar, a grandfon of Augnftus, had an interview with the king of the Parthians, in an ifland of the river Euphrates, in the year 753. He com¬ manded the cavalry in Germany under Tiberius; and accompanied that prince for nine years fucceffively in all his expeditions. He received honourable rewards from him ; but we do not find that he was preferred to any higher dignity than the praetorlhip. Thepraifes he bellows upon Sejanus give fome probability to the conje&ure, that he was looked upon as a friend of this .favourite, and confequently that he was involved in his ruin. His death is placed by Mr Dsdwell in the year of Rome 784, when he was in his 50th year. He wrote an abridgment of the Roman hiftory in two books, which is very curious. His purpofe was only to deduce things from the foundation of Rome to the time wherein he lived, but he began his work with things previous to that memorable aera: for, though Paterculus, the beginning of his firft book is wanting, we yet find in what remains of it, an account of many cities more ancient than Rome. He promifed a larger hiftory ; arid no doubt would have executed it well: for during his military expeditions he had feen, as he tells us, the provinces' of Thrace, Macedonia, Achaia, Afia Minor, and other more eafterly regions; efpecially upon the Ihores of the Euxine fea, which had furnilhed his mind with much entertaining and ufeful knowledge. In the Abridgment which we have, many particulars are rela¬ ted that are no where elfe to be found; and this makes it the more valuable. The ftyle of Paterculus, though miferably difguifed through the careleffnefs of tranferi- bers, and impoffible to be reftored to purity for want of manuferipts, is yet manifeftly worthy of his age, which was the time of pure Latinity. The greateft excellence of this hiftorian lies in bis manner of com¬ mending and blaming thofe he fpeaks of; which he does in the fineft terms and molt delicate expreffions. He is, however, condemned, and indeed with the greateft reafo.n, for his partiality to the houfe of Au- guftus; and for making the moft extravagant eulogies, not only upon Tiberius, but even upon his favourite Se- janus: whom, though a vile and cruel monfter, Parter- culus celebrates as one of the moft excellent perfons the Roman commonwealth had produced. Lipfius, though he praifes him in other refpedls, yet cenfures him moft feverely for his infincerity and partiality. “ Velleius Paterculus (fays he), raifes my indignation: he repre- fents Sejanus as endowed with all good qualities. The impudence of this hiftorian! But we know, that he was born, and died, to the deftru&ion of mankind. After many commendations, he conclude#, that Livia was a woman more refembling the gods than men: and as to Tiberius, he thinks it a crime to fpeak otherwife of him than as of an immortal Jove. What fincere and honeft mind can bear this? On the other hand, how artfully does he every where conceal the great qualities of Cte- far Germanicus! how obliquely does he ruin the repu¬ tation of Agrippina and others, whom Tiberius was thought to hate! In ftiort, he is nothing but a court- proftitute. You will fay, perhaps, it was unfafe to fpeak the truth at thofe times: I grant it; but if he could not write the truth, he ought not to haye writ* ten lies: none are called to account for filence.” La Mothe le Vayer has made a very juft remark upon this occafion: “ The fame fault (fays he) may be obferved in many others, who have written the hiftory of their own times, with a defign to be publiffied while they lived.” It is ftrange, that a work fo elegant and worthy to be preferred, and of which, by reafon of its ftiortnefs, copies might be fo eafily taken, (hould have been fo near being loft. One manufeript only has had the luck to be found, as well of this author among the Latins, as of Hefychius among the Greeks: in which, fays a great critic of our own nation, “ The faults of the icribes are found fo numerous, and the defeats fo be¬ yond all redrefs, that notwithftanding the pains of the Lamed and moft. acute critics for two whole centuries, tfiefe books ftill are, and are like to continue, a ifiere heap of errors.” No ancient author but Prifcian makes mention of Paterculus: the moderns have done him in¬ finitely more juftice, and have iiluftrafed him with notes PAT [ 5909 ] PAT Path and commentaries. He was firft published, from the Patmos roanufcript of Morbac, by Rhenanus, at Bafii in 1520: 11. afterwards by Lipfius at Leyden in 1581; then by Ge¬ rard Voflius in J639; next by Boeclerus at Strafburg 101642; then by Thyfius and others; and, laftly, by Peter Barman at Leyden 1719, in 8vo. To the Ox¬ ford edition in 1693, 8vo, were prefixed the Annales Velleiani of Mr Dodwell, which (hew deep learning and a great knowledge of antiquity.

PATIN (Guy), profefibr of phyfic in the royal col¬ lege of Paris, was born in 1602. He made his way into the world merely by the force of his genius, be¬ ing at firft corrector of a printing-houfe. He was a man of great wit and erudition: he fpoke with the gravity of a Stoic, but his expreffions were very fati- rical. He hated bigotry, fuperftition, and knavery; had an upright foul, and a well-difpofed heart. He was a moft tender father, courteous to every body, and polite in the higheft degree. He died in 1672, and did not owe his reputation to any writings publifhed in his life-time upon phyfic; but l »'s letters which appeared after his death have rendered his name very famous. He left a fon mentioned in the enfuing article. Patin (Charles), who made a great figure in the world, and excelled in the knowledge of medals. He was born in Paris in 1633 ; and made fo furprifing a progrefs, that he maintained thefes in Greek and La¬ tin, on all parts of philofopby, in 1647. He ftudied the law in compliance to an uncle, and was admitted an advocate in the parliament of Paris; but could not lay afide that of phyfic; for which he always had an inclination. He therefore quitted the law, and dlvoted himfelf to phyfic; in which, after taking the doctor’s degree, he applied himfelf to pra&ice, with great fuccefs. He afterwards travelled into Germany, Holland, England, Switzerland, and Italy. In 1676 he was appointed profeffor of pbyfic in Padua; and three years after was created a knight of St Mark. He died in that city in 1694. His works are many, and well known to the learned world. His wife too, and bis daughters, were authoreffes. PATMOS (anc. geog.), one of the Sporades (Bio- nyfius); 30 miles in compafs (Pliny); concerning which we read very little in authors. It was rendered famous by the exile of St John and the Revelation {hewed him there. It is now in the hands of the Turks. It is con- fiderable for its harbours; but the inhabitants derive little benefit from them, becaufe the corfairs have ob¬ liged them to quit the town and retire to a hill on Patna which St John’s convent ftands.

At _ 16 years of age he was made a flave, and continued fo for fix years. Then he became a difciplc of St Mar- tine of Tours, who ordained him prieil, and fent him into Ireland, where he laboured fuccefsfully for 60 years in converting the inhabitants. Patrick (Simon), a very learned Englilh bifltop, was born at Gainfborough in Lincolnfhire in 1626. In 1644 he was admitted into Queen’s college, Cam¬ bridge, and entered into holy orders. After being for fome time chaplain to Sir Walter St John, and vicar of the church at Batterfea in Surry, he was preferred to the redory of St Paul’s, Covent-garden, in London, where he continued all the time of the plague in 1665 among his pariihioners, to their great comfort. In 1668 he publifhed his between a Con- formift and a Non-conformift. This was anfwered by the Diffenters, whom he had much exafperated by it ; but by his moderation and candour toward them after¬ wards, they were perfc&ly reconciled to him, and he brought over many of them to the communion of the eftablilhed church. In 1678 he was made dean of Peterborough, where he was much beloved. In 1682, Hr Lewis de Moulin, who had been a hittory-profef- for at Oxford, and written many bitter books againft the church of England, fent for Dr Patrick upon his fick-bed, and made a folemn declaration of his regret on that account, which he figned, and it was pubidh- ed after his death. During the reign of king James, the dean’s behaviour fhewed that he had nothing more at heart than the Proteftant religion ; for which he ventured all that was dear to him, by preaching and writing againft the errors of the church of Rome. In 1687 he publiflwd a prayer compofed for that difficult time, when perfecution was txpe&ed by all who Hood firm to their religion. The year after the Revolution, the dean was appointed bifti'opof Chichefter, and was employed with others of the new biftvops to fettle the affairs of the church in Ireland. In 1691 he was tranflated to the fee of Ely, in the room of the de¬ prived bifiiop Turner. He died in 1707, after having publiftred various works ; among which the moft di- ftinguiihed are his Paraphrafes and Commentaries on the holy feriptures, 3 volumes folio.

The term patrimony has been alfo given to church- eftates or revenues; in which fenfe authors ftill fay, the patrimony of the church of Rimini, Milan, &c. The church of Rome hath patrimonies in France, A- frica, Sicily, and many other countries. To create the greater refpeft to the eftates belonging to the church, it was ufual to give their patrimonies the-names of the faints they held in the higheft veneration : thua the eftate of the church of Ravenna was called the pa¬ trimony of St Apcllinarius ; that of Milan, the patri¬ mony of St Ambroje; and the eftates of the Roman church were called the patrimony of St Peter in Abruz- zo, the patrimony of St Peter Pi Sicily, and the like. What is now called St Peter's patrimony is only the duchy of Caftro, and the territory of Orvietto. See Castro, &c. PATRIPASSIANS, patripassiani, in church- hiftory, a Chriftian fe£I, who appeared about the lat¬ ter end of the 2d century ; fo called, from their aferi- bing the paffion to the Father; for they afferted the unity of God in fuch a manner as to deftroy all di- ftindions of perfons, and to make the Father and Son precifcly the fame ; in which they were followed by the Sabellians and others. The author and head of the Patripaffians was Praxeas, a philofopher of Phry¬ gia in Alia. PATROL, in war, a round or march made by the guards or watch in the night-time, to obferve what paffes in the ftreets, and to fecure the peace and tran¬ quillity of a city or camp. The patrol generally con- fifts of a body of five or fix men, detached from a bo¬ dy on guard, and commanded by a ferjeant. They go every hour of the night, from the beating of the tattoo until the reveille : they are to walk in the ftreets in garrifons, and all over the camp in the field, to prevent diforders, or any number of people from affembling together; they are to fee the lights in the foldiers barracks put out, and to take up all the foldiers they find out of their quarters. Sometimes patrols confift of an officer and 30 or 40 men, as well infantry as cavalry ; but then the enemy is generally near at hand, and confequently the danger greater. PATRON, among the Romans, was an appellation given to a mailer who had freed his Have. As foon as the relation of mailer expired, that of patron began : for the Romans in giving their Haves their freedom, did not defpoil themielves of all rights and privileges in them ; the law ftill fubje&ed them to confiderable fervices and duties towards their patrons, the negledl of which was very feverely punifhed. Patron was alfo a name which the people of Rome gave to fome great man, under whofe prote&ion they uiually put themfelves ; paying him all kinds of ho¬ nour and refped, and denominating thtmfelves his clients; while the patron, on his fide, granted them his credit and protection. Patron, in the church of Rome, a faint, whofe name a perfon bears, or under whofe protedlion he is put, and whom he takes particular care to invoke : or a PAT [ 59.3 ] PAT |. J>atronagc. a faint, in whofe name a church or order ia founded. * Patron, in the canon and common law, is a per- fon, who having the advowfon of a parfonage, vica¬ rage, or the like fpiritual promotion, belonging to his manor, hath, on that account, the gift and difpofition of the benefice, and may prefent to it whenever it be¬ comes vacant. The patron’s right of difpofing of a benefice, originally arifes either from the patron, or h:sanceftors, See. being the founders or builders, of the church ; from their having given lands for the main- renance thereof; or, from the church’s being built oti their ground; and frequently from all three toge¬ ther. PATRONAGE, or Advowson, a fort of incor¬ poreal hereditament, confiding in the right of prefen- tation to a church or ecclefiaftical benefice. Ad¬ vowfon, advocatio, fignifies in clientela?n rccipere, the taking into proteftion ; and therefore is fynonymous with patronage, patronatus: and Ire who has the right of advowfon is called the patron of the church. Blackjt. For, when lords of manors firft built churches on their Comment, own demefnes, and appointed the tithes of thofe ma¬ nors to be paid to the officiating miniders, which be¬ fore were given to the clergy in common (from whence arofe the divifion of parifhes), the lord, who thus built ‘ a church, and endowed it with glebe or land, had of common right a power annexed of nominating fuch minider as he pleafed, (provided he were canonically qualified), to officiate in that church, of which he was the founder, endower, maintainer, or, in one word, the patron. Advowfons are either advowfons appendant, or ad- vowfons in grofs. Lords of manors being originally the only founders, and of courfe the only patrons, of churches, the right of patronage or prefentation, fo long as it continues annexed to the pcffeffion of the manor, as fome have done from the foundation of the church to this day, is called an advonvfon appendant: and it will pafs, or be conveyed, together with the manor, as incident and appendant thereto, by a grant of the manor only, without adding any other words. But where the property of the advowfon has been once feparated from the property of the manor, by legal conveyance, it is called an advonufon in grofs, or at large, and never can be appendant any more ; but is for the future annexed to the perfon of its owner, and not to his manor or lands. Advowfons are alfo either prefentative, collative, or ■donative. And advowfon prefentative is where the patron hath a right of prefentation to the biihop or ordinary, and moreover to demand of him to inftitute his clerk if he finds him canonically qualified : and this is the moil ufual advowfon. An advowfon colla¬ tive is where the biftiop and patron are one and the fame perfon : in which cafe the bifliop cannot prefent to himfelf; but be does, by the one a£ of collation, or conferring the benefice, the whole that is done in common cafes, by both prefentation and inftitution. An advowfon donative is when the king, or any fub- je by the French and Spaniards in 1745 ; but Paub retaken by the Auftrians in 1746. E. Long. 9. * N.

Pavilions are fometimes alfo projefting pieces, in the front of a building, marking the middle thereof; fome¬ times the pavilion flanks a corner, in which cafe it is called an angular pavilion. The Louvre is flanked with four pavilions: the pavilions are ufually higher than the reft of the building. There are pavilions built in gardens, commonly called fummer-houfes, pleafure- houfes, &c. Some cattles or forts confift only of a iingle pavilion. Pavilion, in military affairs, fignifies a tent raifed on polls, to lodge under in the fummer time. Pavilion, is alfo fometimes applied to flags, co¬ lours, enfigns, ftandards, banners, &c. Pavilion, in heraldry, denotes a covering in form of a tent, which invefts or wraps up the armories of divers kings and fovereigns, depending only on God and theirjword. The pavilion confifts of two parts ; the top, which is the chapeau, or coronet; and the curtain, which makes the mantle. None but fovereign monarchs, according to the French heralds, may bear the pavilion entire, and in all its parts. Thofe who are eleftive, or have any dependence, fay the heralds, mutt take off the head, and retain nothing but the curtains. Pavilions, among jewellers, the underfides and corners of the brilliants, lying between the girdle and the collet. PAUL (St) the apoftle, was born at Tarfus in Cilicia, of Jewifli parents. He was educated at Tar¬ fus ; which, as Strabo informs us, excelled Alexan¬ dria, Athens, and Rome itfelf, for polite learning. Thence he was fent to Jerufalem, to ftudy the law under Gamaliel. Here he became a Pharifee, and engaged in a violent perfecution ; but was wonderfully con¬ verted in his way to Damafcus. After which he preached the gofpel in various parts, until he was at laft fent to Rome, where he is faid to have converted Poppea Sabina, Nero’s concubine ; for which Nero being enraged againft him, commanded him to be beheaded. Paul, firft bilhop of Narbonne, or Sergius Paulus the proconful, converted and made bifhop by St Paul, was defeended form one of !the beft families of Rome. It is faid the apoftle called himfelf Paul from his name. The Spaniards will have him to be their apoftle, which is not improbable; and it is faid he died a martyr at Narbonne. Paul (Father), was born at Venice in 1552. He was educated by his uncle Ambrofio Morelli, and foon made great progrefs in learning. He was re¬ markable for two qualities, which feldom meet in the fame perfon; a ftrong memory, and clear judgment. He took upon him the habit of the Servites in 1566. Upon entering into this order, he changed his name of Peter Sarpi for that of Paul. He was afterwards tfhaplain P A U [ 5915 ] P A U Paul chaplain to the duke of Mantua, and reader of pofi- 81 tive and cafuiftical divinity and canon law in that city. Favo' So he became a perfect mailer of the Hebrew lan¬ guage and of hiftory ; but (hewed the utmoft con¬ tempt for judicial aftrology. When weary of a court life, he returned to his convent at Venice; and fo in- tenfely applied himfelf to ftudy, that he injured his health by it. He was chofen provincial of his order for the province of Venice at 26 years of age ; and dif- charged this poll with fuch honour, that 1759 he was appointed, with two others, to draw up new regula¬ tions and ftatutes for his order. This he executed with great fuccefs; and when his office of provincial was expired, he retired for three years to the ftudy of natural and experimental philofophy and anatomy, in which he is faid to have made fome ufeful difco- veries. He was then chofen procurator-general of his order; and during his refidence at Rome was greatly efteemed by pope Sixtus V. and contradled an inti¬ mate friendftnp with cardinal Bellarmine and other eminent perfons. Some time after, he was accufed of herefy; and brought into a feries of troubles, which he fupported with exemplary patience and magnani¬ mity ; till at length, growing extremely odious to the pope’s party, he was affaffinated, and left for dead, by five ruffians, who retired to the palace of the pope’s nuncio in Venice, from whence they efcaped to Ravenna or Ferrara. Thefe circumftances difco- vered who were concerned in this attempt. He re¬ covered, however, of his wounds; and retired to a place of fecurity, where he wrote his hiftory of the council of Trent, which he compiled principally for the fake of king James I. of England, with whom he correfponded. His name, ever fince the interdid, was become famous all over Europe; and two kings made him very advantageous offers to refide in their dominions. He died as he had lived, with piety and rcfignation, in 1623. He was a good controverfial writer, a judicious and elegant hiftorian. PAULIONISTS, in church-hiftory, Chriftian he¬ retics of the third century, difciples of Paul Samota- fenfis bifhop of Antioch, who denied Chrift’s divinity; maintaining, that, when we call him the Son of God, we do not therefore mean that he is truly and really God ; but only that he was fo perfect a man, and fo fuperior in virtue to all others, that he had this name given him by way of eminence. PAUL1CIANS, Chriftian heretics of the feventh century, difciples of one Conftantine a native of Ar¬ menia, and a favourer of the errors of Manes ; who, as the name Manichee was become odious, gave thofe of his fed the name of Paulicians, on the pretence that they followed only the do&rine of St Paul. PAVO, the peacock, in ornithology; a genus be- longing to the order of gallinas. The head is co¬ vered with feathers which bend backwards; the fea¬ thers of the tail are very long, and beautifully va¬ riegated with eyes of different colours. There are three fpecies. 1. The criftatus, or common peacock of Engliffi authors, has a compreffed creft and folitary fpurs. It is a native of India ; and we are affured, that they are Hill found in a wild ftate in the iflands of Ceyland and Java. So beautiful a bird could not long be permitted to be a ftranger in the more diftant parts ; for fo early 2 as the days of Solomon, we find, among the articles Pavo imported in his Tarlhifh navies, apes and peacocks. A i! monarch fo converfant in all branches of natural hi- ftory, “ who fpoke of trees, from the cedar of Leba¬ non, even unto the hyffop that fpnngeth out of the wall; who fpoke alfo of beafts and of fowl,” would certainly not negleft furnilhing his officers with in- ftru&ions for collefting every curiolity in the coun¬ tries they voyaged to, which gave him a knowledge that diftinguifhed him from all the princes of his time. iElian relates, that they were brought into Greece from fome barbarous country; and that they were held in fuch high efteem, that a male and female were va¬ lued at Athens at 1000 drachmas, or 32 1. 3 s. 10 d. Their next ftep might be to Samos; where they were preferred about the temple of Juno, being the birds fa- cred to the goddefs: and Gellius, in his Nodes Attics, c. 16. commends the excellency of the Samian pea¬ cocks. It is therefore probable, that they were brought here originally for the purpofes of fuperfti- tion, and afterwards cultivated for the ufes of luxury.' We are alfo told, when Alexander was in India, he found vaft numbers of wild ones on the banks of the Hyarotis; and was fo ftruck with their beauty, as to appoint a fevere punifhment on any perfon that kill¬ ed them. Peacock’s crefts, in ancient times, were among the ornaments of the kings of England. Ernald de Ac- lent was fined to king John in 140 palfries, with fack- buts, lorains, gilt fpurs, and peacock’s crefts, fuch as would be for his credit. 2.

PAUSANIAS,a learned Greek hiftorian and ora¬ tor, in the fecond century, under the reign of Antoni¬ nus the philofopher, was the difciple of Herodus At- ticus. He lived for a long time in Greece ; and af¬ terwards went to Rome, where he died at a great age. He wrote an excellent Defcription of Greece, in ten books; in which we find not only the fituation of places, but the antiquities of Greece, and every thing moft curious and worthy of knowledge.

See Pavo, PEAK of Derbyshire, a chain of very high mountains in the county of Derby in England, famous for the mines they contain, and for their remarkable caverns. The moft remarkable of thefe are Pool’s* hole and Elden-hole. The former is a cave at the foot of a high hill called Coitmofs} fo narrow at the en¬ trance that paflengers are obliged to creep on all-fours; but it foon opens to a confiderable height, extending to above a quarter of a mile, with a roof fomewhat re- fembling that of an ancient cathedral. By the petrify¬ ing water continually dropping in many parts of the cave are formed a variety of curious figures and re- prefentations of the works both of nature and art. There is a column here as clear as alabafter, which is called the Queen of Scots Pillar, becaufe Queen Mary is faid to have proceeded thus far when fhe vifited the cavern. If a piftol is fired by this pillar, it will make a report as loud as a cannon. Near the extremity there is a hollow in the roof, called the Needle's eye; in which if a candle is placed, it will reprefent a liar in the firmament to thofe who are below. At a little diftance from this cave is at fmall clear ftream con- fifting of hot and cold water, fo near each other, that the finger and thumb of the fame hand may be put, the one into the hot water, and the other into the cold. Eiden-hole is a dreadful chafm in the fide of a moun¬ tain ; which, before the latter part of the laft cen¬ tury, was thought to be altogether unfathomable. In the time of queen Elizabeth, a poor man was let down into it for 200 yards; but he was drawn up in a frenzy, and foon after died. In 1682, it was exami¬ ned by Captain Collins, and in 1699 by Captain Stur- my, who publilhed their accounts in the Philofophical Tranfadtions. The latter defcended by ropes fixed at the top of an old lead-ore pit, four fathoms almoll perpendicular, and from thence three fathoms more obliquely, between two great rocks. At the bottom of this he found an entrance into a very fpacious ca¬ vern, from whence he defcended along with a miner for 25 fathoms perpendicular. At laft they came to a great river or water, which he found to be 20 fa¬ thoms broad and eight fathoms deep. The miner who accompanied him, infilled that this water ebbed and flowed with the fea ; but the Captain difproved this aflertion by remaining in the place from three hours flood to two hours ebb, during which time there was no alteratiun in the height of the water. As they walked by the fide of this water, they obferved a hol¬ low in the rock fome feet above them. The miner went into this place, which'was the mouth of another cavern; and walked for about 70 paces in it, till he juft loft fight of the Captain. He then called to him, that he had found a rich mine; but immediately after came running out and crying,, that he had feen an evil fpi- rit; neither could any perfuafions induce him to re¬ turn. The floor of thefe caverns is a kind of white flone enamelled with lead ore, and the roofs are en- crulled with fhining fpar. On his return from this fub- terraneous journey, Captain Sturroy was fei&ed with a 16 ] PEA violent head-ach, which, after continuing four days, terminated in a fever, of which he died in a fhort time. A few years ago this cavern was rifited by the late Mr James Fergufon : who tells us, that it confifts of two hollows one over another ; but that the mouth of the lowermoft is now flopped up by planks of timber laid acrofs it, on which are a heap of ftones thrown in at the upper mouth with a defign to fill up the cavern entirely ; which, however, will probably be never ac- complilhed on account of its vatl fize.

He married Mifs Adams, the daughter of a diftiller in the fame neigh-' bourhood, with a confiderable fortune, who lived with him 52 years in the higheft degree of connubial hap- pinefs. He had his education in Weftminfter fchool, where he was diftinguilhed by his merit, and ele&ed one of the king’s fcholars. In 1710, when he was 20 years old, he was defied to Trinity College, Cam¬ bridge. During the firft years of his refidence at the univerfity, he fometimes amufed himfelf with lighter compofitions, fome of which are inferted in the Guar¬ dian and Speflator. In 1716, he publifhed his edi¬ tion of Cicero de Oratore, and, at the defire of a friend, luckily dedicated it to Lord Chief Juftice Parker, (af¬ terwards Earl of Macclesfield,) to whom he was a ftranger. This incident laid the foundation of his fu¬ ture fortune : for Lord Parker foon recommended him to Dr Bentley, mailer of Trinity, to be made one of the fellows; and the doflor confented to it on this condition, that his lordlhip would promife to unmake him again as foon as it lay in his power to give him a living. In 1717, Mr Pearce was ordained at the age of 27 ; having taken time enough, as he thought, to attain a fufficient knowledge of the facred office. In 1718, Lord Parker was appointed chancellor, and invited Mr Pearce to live with him in his houfe as chaplain. In 1719, he was inftituted into the redtory of Stapleford Abbots, in Effex; and in 1720, into that of St Bartholomew, behind the Royal Exchange, worth 400 1. per annum. In 1723, the lord chancel¬ lor prefented him to St Martin’s in the Fields. His Majefty, who was then at Hanover, was applied to in- favour of St Claget, who was then along with him ; and the doflor aflually kiffed hands upon the occa- fion : but the chancellor, upon the king’s return, dif- puted the point, and was permitted to prefent Mr Pearce.—Mr Pearce foon attradled the notice and efteem of perfons in the higheft ftations and of the greateft abilities. Befide Lord Parker, he could rec¬ kon amongft his patrons or friends, Lord Maccles¬ field, Mr Pulteney (afterwards Earl of Bath), arch- bilhop Potter, Lord Hardwicke, Sir Ifaac Newton, and other illuftrious perfonages.—In 1724, the de¬ gree of doctor of divinity was conferred on him by archbilhop Wake. The fame year he dedicated to his patron, the Earf of Macclesfield, his edition of Lon~ ginus on the Sublime, with a new Latin verfion and notes. When the church of St Martin’s was rebuilt, Dr Pearce preached, a fermon at the confecration, which he Pesn n II Pearce. P E A [ 59 Pearce, he afterwards printed, and accompanied with an eflay ' on the origin and progrefs of temples, traced from the rude ftones which were firft ufed for altars, to the noble ftrufture of Solomon, which he confiders as the firft temple completely covered. His obfervations on that building, which is called the temple of Dagon, r?mo\e$ part of the difficulty which prefents itfelf in the nar¬ ration of the manner in which Samfon deftroyed it. The deanry of Winchefter becoming vacant, Dr Pearce was appointed dean it) 1739; and in the year 1744. he was ele&ed prolocutor of the lower houfe of convocation for the province of Canterbury. His friends now began to think of him for the epifcopal dignity ; but Mr Dean’s language rather delined it. However, after feveral difficulties had been ftarted and removed, he confented to accept the bifhoprick of Bangor, and promifed Lord Hardwicke to do it with a good grace. He accordingly made proper acknowledgments of the royal goodnefs, and was confecrated Feb. 12. 1748. Upon the declining ftate of health of Dr Wilcocks, bilhop of Rochefter, the bilhop of Bangor was feveral times applied to by archbifhop Herring to accept of Rochefter, and the deanry ofWeftminfter, in exchange for Bangor; but the bifhop then firft fignified his de¬ fire to obtain leave to refign and retire to a private life. His lordfhip, however, upon being preffed, fuf- fered himfelf to be prevailed upon “ My Lord,” faid he to the Duke of Newcaftle, “ your grace offers thefe dignities to me in fo generous and friendly a man¬ ner, that I promife you to accept them.” Upon the death of bifhop Wilcocks he was accordingly promp¬ ted to the fee of Rochefter and deanry ofWeftminfter in 1756. Biftiop Sherlock died in 1761, and Lord Bath offered his intereft for getting the bifhop of Ro- chefter appointed to fucceed him in the diocefe of Lon¬ don ; but the bifhop told his lordfhip, that he had de¬ termined never to be bifhop of London or archbifhop of Canterbury. In the year 1763, his lordfhip being 73 years old, and finding himfelf lefs fit for the bufinefs of his Rations as bifhop and dean, informed his friend lord Bath of his intention to rdign both, and live in a retired man¬ ner upon his private fortune. Lord Bath undertook to acquaint his majefty ; who named a day and hour, when the bifhop was admitted alone into the clofet. He told the king, that he wifhed to have fame inter¬ val between the fatigues of buftnefs and eternity; and defired his majefty to confult proper perfons about the propriety and legality of his refignation. In about two months the king informed him, that Lord Mans¬ field faw no objeftion ; and that Lord Northington, who had been doubtful, on farther confideration thought that the requeft might be complied with. Unfortunately for the bifhop, lord Bath applied for bifhop Newton to fucceed. This alarmed the mini- ftry, who thought that no dignities fhould be obtain¬ ed but through their hands. They therefore oppofed the refignation ; and his majefty was informed that the bifhops difliked the defign. His majefty fent to him again ; and at a third audience told him, that he muft think no more of refigning. The bifhop replied, u Sir, I am all duty and tubmifiion;” and then retired. „ In 1768 he obtained leave to refign the deanry ; in 1773, he loft his lady ^ and after fome months of ling¬ ering d^cay, he died at Little Ealing, June 29, 1774. 17! PEA This eminent prelate diftinguifked himfelf in every Pearch. part of his life by the virtues proper to his Ration. His literary abilities, and application to facred and philological learning, appear by his works ; the prin¬ cipal of which are, A letter to the clergy of the church of England, on occafion of the bifhop of Rochefter’s commitment to the Tower, 2d ed. 1722.

PEARCH, in ichthyology. See Perca. The pearch affords good fport for the angler. The beft time for their biting is when the fpring is over, and before the heats of fummer come on. At this time they are very greedy ; and the angler, with good management, may take at one Handing all that are in the hole, be they ever fo many. The proper baits are a minow or young frog ; but the worm called the brandling, well fcowered, is alfo excellent at all times of the year. When the pearch bites, he fhould always have a great deal of time al¬ lowed him to fwallow the bait. The pearch will bite all day long, if the weather be cloudy ; but the beft time is from eight to ten in the morning, and from three till fix in the afternoon. The pearch is very abftemious in winter, and will fel- dom bite in this feafon of the year ; if he does at all, it is in the middle of the day : at which time indeed all fifh bite beft at that feafon. If the bait be a minow, which is the bait that af¬ fords moft diverfion to the angler, it muft be faftened to the hook alive, by putting the hook through the upper lip or back-fin; it muft; be kept at about mid¬ water, and the float muft be a quill and a cork, that the minow alone may not be able to fink it. The line muft be of filk, and ftrong ; and the hook armed with a final] and fine wire, that if a pike fhould take the bait, as is not unfrequently the cafe, he may¬ be taken. The way to carry the minows or fmall gudgeons alive for baits is this: A tin-pot is to be provided, with holes in the lid, and filled with water;, and the fifh being put in this, the water is to be chats- ged once in a quarter of an hour by the holes, with¬ out taking off the lid at any time, except when the bait is to be taken out. A fmall cafting-net, made for thefe little fifh, fhould be taken out with the pearch-tackle ; and one or two- cafts of this will take baits enough for the day, with¬ out any farther trouble. When the bait is a frog, the hook is to be faftened to the upper part of the leg. The beft. place for the fifhing for pearch is in the turn of the water near fome gravelly fcour. A place of this kind being pitched upon, it fhould be baited over-night with lobworms chopped to pieces; and in the morning, on going to it, the depth is to- be regularly plumbed, and then the hook is to be baited with the worm or other bait; and as it drags %|ong, the pearch will foon feize upon iu PEA Pearch, PEAftCH-G/^, the name of a kind of glue, of re- Pearl, markable ftrength and purity, made from the (kins of pearches. PEARL, in natural hiftory, a hard, white, (hi- ning body, ufually roundilh, found in a teftaceous filh refembling an oyfter. Pearls, though efteemed of the number of gems by our jewellers, and highly valued, not only at this time, but in all ages, proceed only from a diftemper in the creature that produces them, analagous to the bezoars, and other ftony concretions in feveral animals of other kinds. The fi(h in which thefe are ufually produced is the Eaft-Indian pearl-oyfter, as it is commonly called. Befides this (hell, there are many others that are found to produce pearls ; as the common oyfter, the mufcle, and feveral others ; the pearls of which are often very good ; but thofe of the true Indian berberi, or pearl- oyfter, are in general fuperior to all. The fmall or feed-pearls, alfo called ounce-pearls, from their being fold by the ounce and not by tale, are vaftly the moft numerous and common : but, as in diamonds, among the multitudes of fmall ones, there are fmaller numbers and larger found, fo in pearls there are larger and larger kinds ; but as they increafe in fize, they are proportionably lefs frequent; and this is one rea- fon of their great price. We have Scotch pearls fre¬ quently as big as a little tare, fome as big as a large pea, and fome few of the fize of a horfe-bean ; but thefe are ufually of a bad fhape, and of little value in proportion to their weight. Philip II. of Spain had a pearl perfeft in its fhape and colour, and of the fize of a pigeon’s egg. The fineft, and what is called the true fhape of the pearl, is a perfeft round ; but if pearls of a confiderable fize, are of the fhape of a pear, as is not unfrequently the cafe, they are not lefs va¬ lued, as they ferve for ear-rings and other ornaments. Their colour ought to be a pure white ; and that not a dead andlifelefs, but a clear and brilliant one : they muft be perfeftly free from any foulnefs, fpot, or ftain ; and their furfaces muft be naturally fmooth and glofly ; for they bring their natural polifh with them, which art is not able to improve. All pearls are formed of the matter of the fhell, and confift of a number of coats fpread with perfedt regularity one over another, in the manner of the fe¬ veral coats of an onion, or like the feveral ftrata of the flones found in the bladders or ftomachs of ani¬ mals, only much thinner. Manner of fijhing for Pearls in the Eajl Indies. There are two feafons for pearl-fifhiug : the firft is in March and April, and the laft in Auguft and Septem¬ ber ; and the more rain there falls in the year, the more plentiful are thefe fifheries. At the beginning of the feafon there are fometimes 250 barks on the banks; the larger barks have two divers, and the fmaller one. As foon as the barks arrive at the place where the fifh lie, and have caft anchor, each diver binds a ftone, fix inches thick and a foot long, under his body ; which ferves him as ballaft, prevents his being driven away by the motion of the water, and enables him to walk -more fteadily under the waves. They alfo tie another very heavy ftone to one foot, by which they are very fpeedily fent to the bottom of the fea ; aod as the oyfters are ufually firmly fattened to PEA the rocks, they arm their hands with leather mittens, Peart* to prevent their being wounded in pulling them vio- lently off; but this talk fome perform with an iron rake. In the laft place, each diver carries down with him a large net in the manner of a fack, tied to his neck by a long cord, the other end of which is fattened to the fide of the bark. This net is to hold the oyfters gathered from the rock; and the cord is to pull up the diver when his bag is full, or he wants air. In this equipage he fometimes precipitates him- felf fixty feet under water ; and as he has no time to lofe, he no fooner arrives at the bottom, than he be¬ gins to run from fide to fide, tearing up all the oy¬ fters he meets with, and cramming them into his bud- get. At whatever depth the divers are, the light is fo great, that they eafily fee whatever paffes in the fea ; and, to their great confternation, fometimes perceive monftrous fifties, from which all their addrefs in mud¬ dying the water, &c. will not always fave them, but they unhappily become their prey : and of all the dangers of the fiftiery, this is one of the greateft and moft ufual. The beft divers will keep under water near half an hour, and the reft do not flay lefs than a quarter. During this time they hold their breath without the ufe of oils or any other liquors; only acquiring the habit by long praftice. When they find themfelves ftraitened, they pull the rope to which the bag is fattened, and hold fall by it with both hands ; when thofe in the bark, taking the fig- nal, heave them up into the air, and unload them of their fifti; which is fometimes 500 oyfters, and fome¬ times not above 50. Some of the divers need a mo¬ ment’s refpite to recover breath ; others jump in again inftantly, continuing this violent exercife without in- termiflion for feveral hours. On the ftiore they unload their barks, and lay their oyfters in an infinite number of little pits dug in the fand four or five feet fquare, raifing heaps of fand over them to the height of a man ; and in this condi¬ tion they are left till the rain, wind, and fun, have obliged them to open, which foon kills them : upon this the flefh rots and dries, and the pearls, thus difen- gaged, fall into the pit, on their taking out the {hells. After clearing the pits of the groffer filth, they fift the fand feveral times in order to find the pearl; but, whatever care they take, they always lofe a great many. After cleaning and drying the pearls, they are paffed through a kind of fieve, according to their fizes ; the fmalleft are then fold as feed-pearls, and the reft put up to au&ion, and fold to the higheft bidder. Artificial H'e.kKx.s. Attempts have been made to take out ftains from pearls, and to render the foul opaque-coloured ones equal in luftre to the oriental. Abundance of proceffes are given for this purpofe in books of fecyets and travels ; but they are very far from anfwering what is expefted from them. Pearls may be cleaned indeed from any external foulneffes by wafhing and rubbing them with a little Venice foap and warm water, or with ground rice and fait, with ftarch and powder-blue, plafter of Paris, coral, white vitriol and tartar, cuttle-bone, pumice-ftone, and other fimilar fubftances; but a ftain that reaches deep into [ 59l8 1 PEA [ 5919 ] PEA into the fubftance of the pearls is impoffible to be taken out. Nor can a number of fmall pearls be uni¬ ted into a mafs fimilar to an entire natural one, as fome pretend. There are, however, methods of making artificial pearls, in fuch manner as to be with difficulty diftin- guifhed from the beft oriental. The ingredient ufed for this purpofe was long kept a fecret; but is now difcovered to be a fine filver-like fubftance found upon the under fide of the fcales of the blay or bleak fifh. The fcales, taken off in the ufual manner, are wafhed and rubbed with frefh parcels of fair water, and the feveral liquors fuffered to fettle : the water being then poured off, the pearly matter remains at the bottom, of the confiftence of oil, called by the French ejence d’orient. A little of this is dropped into a hollow bead of bluifh glafs, and fhaken about fo as to line the internal furface ; after which the cavity is filled up with wax, to give folidity and weight. Pearls made in this manner are diftinguilhable from the natural only by their having fewer blemifhes. Mother-of-X!*.kv>\. is the (hell, not of the pearl oyfter, but of another fea-filh of the oyfter kind. This fhell, on the infide, is extremely fmooth, and of the white- nefs and water of pearl itfelf: it has alfo the fame luftre on the outfide after the external laminae have been ta¬ ken off by aquafortis and the lapidary’s mill. Mo¬ ther of pearl is ufed in inlaid works, and in feveral toys, as fnuff-boxes, &c. PEARSON (John), a very learned Englifh biftiop in the 17th century, was born at Snoring in 1613. After his education at Eton and Cambridge, he enter¬ ed into holy orders in 1639, and was the fame year col¬ lated to the prebend of Netherhaven in the church of Sarum. In 1640 he was appointed chaplain to the lord keeper Finch, and by him prefented to the living of Torrington in Suffolk. In 1650 he was made minifter of St Clement’s, Eaft-cheap, in London. In 1657, he and Mr Gunning had a difpute with two Roman Ca¬ tholics, upon the fubjeft of fchifm ; a very unfair ac¬ count of which was printed at Paris in 1658. Some time after, he publilhed his Expofition of the Creed, and feveral other works. After various preferments, he was advanced in 1672 to the fee of Chefter; where he died, in 1686. PEAT, a kind of turf ufed for fuel in feveral coun¬ tries. See Chemistry, n°5i6. There are very confiderable differences in peat, pro¬ ceeding perhaps wholly from different mineral admix¬ tures; for the fubftance of the peat is plainly of vege¬ table origin, whence it is found to anfwer for the fmelt- ing of ores, and the redu&ion of metallic calces, nearly in the fame manner as the coals of wood. Some forts yield in burning a very difagreeable fmell, which ex¬ tends to a great diftance; whilft others are inoffenfive. Some burn into grey or white, and others into red fer- rugineous allies. The alhes yield, on elixation, a fmall quantity of alkaline fait, with fometimes one and fome- times another fait of the neutral kind. The fmoke of peat does not preferve or harden flelh like that of wood ; and the foot, into which it con- denfes, is more difpofed to liquefy in moift weather. On diftilling peat in clofe veffels, there arifes a clear in- fipid phlegm, an acid liquor, which is fucceeded by an alkaline one, and a dark coloured oil. The oil has a very pungent tafte; and an empyreumatic fmell, lefs fetid than that of animal fubftances, more fo than that J[ of mineral bitumens : it congeals in the cold into a Pc e-- pitchy mafs, which liquefies in a fmall heat: it readily catches fire from a candle, but burns lefs vehemently than other oils, and immediately goes out upon remo¬ ving the external flame: it diffolves almoft totally in reflified fpirit of wine into a dark brownifh red li¬ quor. PEBBLES, the name of a genus of folfils, diftin- guilhed from the flints and horaochroa by their ha¬ ving a variety of colours. Thefe are defined to be ftones compofed of a cryftalline matter debafed by earths of various kinds in the fame fpecies, and then fubjeft to veins, clouds, and other variegations, ufually formed by incruftation round a central nucleus, but fometimes the effeft of a Ample concretion ; and veined like the agates, by the difpofition which the motion of the fluid they were formed in gave their differently co¬ loured fubftances. The variety of pebbles is fo great, that an hafty de- fcriber would be apt to make almoft as many fpecies as he faw fpecimens. A careful examination will teach us, however, to diftinguifh them into a certain number of effentially different fpecies, to which all the reft may be referred as accidental varieties. When we find the fame colours, or thofe refulting from a mixture of the fame, fuch as nature frequently makes in a number of ^ftones, we (hall eafily be able to determine that thefe are all of them the fame fpecies, though of different appearances; and that whether the matter be difpofed of in one or two, or in 20 crufts, laid regularly round a nucleus; or thrown irregularly, without a nucleus, into irregular lines ; or laftly, if blended into an uni¬ form mafs. Thefe are the three dates in which every pebble is found; for if it has been naturally and regularly form¬ ed by incruftation round a certain nucleus, we find that always the fame in the fame fpecies, and the crufts not lefs regular and certain. If the whole has been more haftily formed, and the refult only of one fimple con¬ cretion, if that has happened while its different fub¬ ftances were all moift and thin, they have blended to¬ gether and made a mixed mafs of the joint colour of them all. But if they have been fomething harder when this has happened, and too far concreted to dif- fufe wholly among one another, they are found thrown together into irregular veins. Thefe are the natural differences of all the pebbles; and having regard to thefe in the feveral variegations, all the known pebbles may be reduced to 34 fpecies. PECCANT, in medicine, a term ufed for thofe hu¬ mours of the body which offend either by their quan¬ tity or quality. PECCARY, or Tajacu, in zoology; a fpecies of Sus. PECK, a meafure of capacity, four of which make a bufhel. PECORA, in zoology, the fifth order of the clafs mammalia, in the Linnean fyftem. See Zoology. PECTEN, the Scallop; a genus of (hell-fifti, the charafters of which are thefe: The animal is a tethys; the (hell bivalve and unequal; the hinge toothlefs, ha¬ ving a fmall ovated hollow. This (hell-fi(h is one of the fpianers, having the power of fpinning threads like the mufde PEC [ 5920 ] P E D Feforal mufcle: but they are much fhorter and coarfer than II.. even thofe of that fifh; fo that they can never be ecoiuir. wrought into any kind of work like the longer and finer threads of the pinna marina. The ufe of the threads Which are fpun by the fcallop is to fix the creature to any folid body near its fhell. All thefe proceed, as in the mufcle, from one common trunk. It is an evident proof that the filh has a power of fixing itfelf at plea- lure to any folid body by means of thefe threads, that after ftorms the fcallops are often found toffed upon rocks, where there were none the day before; and yet thefe are fixed by their threads, as well as thofe which had remained ever fo long in their place. They form their threads in the very fame manner with the mufcle; only their organ which ferves for fpinning is (horter, and has a wider hollow, whence the threads are necef- farily thicker and (horter. The moft remarkable fpe- cies of this genus is, The maxim US', or great fcallop, with 14 rays, very rominent and broad; ftriated lengthwife above and elow. Thefe grow to a large fize; are found in beds by themfelves; are dredged up, and barrelled for fale. The ancients fay that they have a power of removing themfelves from place to place by vaft fprings or leaps. This (hell was called by the Greeks by the La¬ tins petten; and was ufed by both as a food. When drdfed with pepper and cummin, it was taken medici¬ nally. The fcallop was commonly worn by pilgrims on their hat, or the cape of their coat, as a mark that they had croffed the fea in their way to the Holy Land, or fome diftant objeft of devotion. PECTORAL, an epithet for medicines good in dif- eafes of the bread and lungs. PECTORALIS, in anatomy. See there, Table of the Mufcles. PECULATE, in civil law, the crime of embezzling the public money, by a perfon intruded with the re¬ ceipt, management, or cudody thereof. This term is alfo ufed by civilians for a theft, whether the thing be public, fifcal, facred, or religious. PECULIAR, in the canon law, fignifies a particu¬ lar paridi or church that has jurifdiAion within itfelf for granting probates of wills and adminidrations, ex¬ empt from the ordinary or biftrop’s courts. The king’s chapel is a royal peculiar, exempt from all fpiritual ju- rifdiftion, and referved to the vifitation and immediate government of the king himfelf. There is likewife the archbilhop’s peculiar; for it is an ancient privilege of the fee of Canterbury, that wherever any manors or advowfons belong to it, they forthwith become exempt from the ordinary, and are reputed peculiars: there are 57 fuch peculiars in the fee of Canterbury. Befides thefe, there are fome peculiars belonging to deans, chapters, and prebendaries, which are only ex¬ empted from the jyrifdiftion of the archdeacon: thefe are derived from the bifhop, who may vifit them, and to whom there lies an appeal. Peculiars [Court of),\s a branch of, and annexed to, the court of arches. It has a jurifdiftion over all thofe paridies difperfed'through the province of Can¬ terbury in the midd of other diocefes, which are exempt from the ordinary’s jurifdidlion, and fubjeft to the me¬ tropolitan only. All ecclefiadical caufes, arifing with¬ in thefe peculiar or exempt jurifdidions, are originally cognizable by this court; from which an appeal lay formerly to the pope, but now by the dat. 25 H. VIIL c. 19. to the king in chancery. PECULIUM, the dock or edate which a perfon, in the power of another, as a flave, may acquire by his indudry. In the Romidr church, peculium denotes the goods which each religious referves and podeffes to himfelf. PEDALS, the larged pipes of an organ, fo called becaufe played and dopped with the foot. The pedals are made fquare, and of wood; they are ufuaily 13 in number. They are of modern invention, and ferve to to carry the founds of an o&ave deeper than the red. See Organ. PEDAGOGUE, or Pedagogue, a tutor or ma- der, to whom is committed the difeipline and dire&ion of a fcholar, to be indru&ed in grammar and other arts. The word is formed from the Greek »««!'»»uyuyos, puerorum duttor, “ leader of boys.” M. Fleury obferves, that the Greeks gave the name pcedagogus to flaves appointed to attend their children, lead them, and teach them to walk, &c. The Romans gave the fame denomination to the flaves who were in¬ truded with the care and inftru&ion of their children. PEDANT, a fchool-mader, or pedagogue, who profedes to indruA and govern youth, teach them the humanities, and the arts. See Pedagogue. Pedant is alfo ufed for a rough, unpoliflied man of letters, who makes an impertinent ufe of the fciences, and abounds in unfeafonable criticifms and obferva- tions. Dacier defines a pedant, a perfon who has more read¬ ing than good fenfe. See Pedantry. Pedants are people ever armed with quibbles and fyl- logifms; breathe nothing but difputation and chican- ry, and purfue a propofition to the lad limits of lo¬ gic. Malebranche deferibes a pedant as a man full of falfe erudition, who makes a parade of his knowledge, and is ever quoting fome Greek or Latin author, or hunt¬ ing back to a remote etymology. St Evremont fays, that to paint the folly of a pe¬ dant, we mud reprefent him as turning all converfation to fome one fcience or fubje& he is bed acquainted withal. There are pedants of all conditions, and all robes. Wicquefort fays, an ambadador, always attentive to formalities and decorums, is nothing elfe but a politi¬ cal pedant. PEDANTRY, or PEDANTisM,the quality or man¬ ner of a pedant. See Pedant. To fwell up little and low things, to make a vain (how of fcience, to heap up Greek and Latin without judgment, to tear thofe to pieces who differ from us about a paffage in Suetonius or the etymology of a word, to dir up all the world againd a man for not admiring Cicero enough, to be intereded for the re¬ putation of an ancient as if he were our next of kin, is what we properly call pedantry. FEDARIAN, in Roman antiquity, thofe fenators who fignified their votes by their feet, not their tongues; that is, fuch as walked over to the fide of thofe whofe opinion they approved of, in divilions of the houfe. PEDERASTS, the fame with Sodomites. PEDESTAL, in architecture, the lowed part of an Peculium « Pedeftal. Pedicle, Pediculus. P E D [ 5921 ] P E D an order of columns, being that part which fuftains the column, and ferves it as a foot or Hand. See Column. PEDICLE, among botanifts, that part of a (talk which immediately fuftains the leaf of a flower or a fruit, and is commonly called a footjialk. PEDICULUS, the Louse, in zoology, a genus of infefts belonging to the order of aptera. It has fix feet, two eyes, and a fort of fting in the mouth; the feelers are as long as the thorax; and the belly is dc- preffed and fublobated. Many animals both of the quadruped and flying kinds are fubjeft to lice; but thefe are of peculiar fpe- cies on each animal, and are not at all like thofe which infeft the human body. Nay, even infers are infefted with vermin'which feed on and torment them. Seve¬ ral kinds of beetles are fubjecl to lice; but particu¬ larly that kind called thence tht loufy beetle. The lice on this are very numerous, and will not be Ihook off. The earwig is often infefted with lice, juft at the fel¬ ting on of its head: thefe are white, and fhining like mites, but they are much fmaller; they are round- backed, flat bellied, and have long legs, particularly the foremoft pair. Snails of all kinds, but efpecially the large naked forts, are very fubjedl to lice ; which are continually feen running about them, and devour¬ ing them. Numbers of little red lice, with a very ftnall head, and in fhape refembling a tortoife, are of¬ ten feen about the legs of fpiders, and they never leave the animal while he lives; but if he is killed, they al- moft inftantly forfake him. A fort of whitifh lice is found on humble-bees: they are alfo found upon ants; and fifties are not lefs fubjedl to them than other ani¬ mals. Kircher tells us, that he found lice alfo on flies, and M. de la Hire has given a curious account of the crea¬ ture which he found on the common fly. Having oc- cafion to view a living fly with the microfcope, he ob- ferved on its head, back, and fhoulders, a great num¬ ber of fmall animals crawling very nimbly about, and often climbing up the hairs which grow at the origin of the fly’s legs. He with a fine needle took up one of thefe, and placed it before the microfcope ufed to view the animalcules in fluids. It had eight legs; four on each fide. Thefe were not placed very diftant from each other; but the four towards the head were fepa- rated by a fmall fpace from the four towards the tail. The feet were of a particular ftrufture, being compo- fed of feveral fingers, as it were, and fitted for taking fait hold of any thing; but the two neareft the head •were alfo more remarkable in this particular than thofe near the tail; the extremities of the legs for a little way above the feet were dry and void of flefh like the legs of birds, but above this part they appeared plump and flefhy. It bad two fmall horns upon its head, formed of feveral hairs arranged clofely together; and there were fome other clufters of hairs by the fide of thefe horns, but they had not the fame figure; and towards the origin of the hinder legs there were two other fuch clufters of hairs which took their origin at the middle of the back. The whole creature was of a bright yel- lowifh red; the legs, and ail the body, except a large fpot in the centre, were perfeftly tranfparent. In fize, he computed it to be about ^-oVo-th Part t^ie ^eac^ the fly; and he obferves, that fuch kind of vermin are rarely found on flies. Vol. VIII. 3 The loufe which infefb the human body makes a P«<3 very curious appearance through a microfcope. It has fuch a tranfparent fhell or flcin, that we are able to difcoyer more of what pafles within its body than in molt other living creatures. It has naturally three di- vifions, the head, the breaft, and the tail part. In the head appear two fine black eyes, with a horn that has five joints, and is furrounded with hairs handing before each eye; and from the end of the nofe or fnout there is a pointed projefting part, which ferves as a Iheath or cafe to a piercer or fucker, which the crea¬ ture thrufts into the fltin to draw out the blood and humours which are its deftined food ; for it has no mouth that opens in the common way, This piercer or fucker is judged to be 700 times fmaller than a hair, and is contained in another cafe within the firft, and can be drawn in or thruft out at pleafure. The breaft is very beautifully marked in the middle; the flcin is tranfparent, and full of little pits; and from the under part of it proceed fix legs, each having five joints, and their flcin all the way refembling fhagreen, except at the ends where it is fmoother. Each leg is terminated by twa claws, which are hooked, and are of an unequal length and fize. Thefe it ufrs as we would a thumb and middle finger ; and there are hairs between thefe claws as well as all over the legs. On the back part of the tail there may be difcovered fome ring-like divifions, and a fort of marks which look like the ftrokes of a rod on the human flcin ; the belly looks like fhagreen, and towards the lower end it is very clear, and full of pits: at the extremity of the tail there are two femicircular parts all covered over with hairs, which ferve to conceal the anus. When the loufe moves its legs, the motion of the mufcles, which all unite in an oblong dark fpot in the middle of the breaft, may be difttnguifhed perfe&!y, andfo may the motion of the mufcles of the head when it moves its horns. We may likewife fee the various ramifica¬ tions of the veins and arteries, which are white, with the pulfe regularly beating in the arteries. But the moft furprifing of all the fights is the periftaltic motion of the guts, which is continued all the way from the ftomach down to the anus. If one of thefe creatures, when hungry, be placed on the back of the hand, it will thruft its fucker into the fkin, and the blood which it fucks may be feen pafiing in a fine ftream to the fore-part of the head ; where, falling into a roundifh cavity, it pafies again in a fine ftream to another circular receptacle in the middle of the head ; from thence it runs thro’ a fmall veffel to the breaft, and then to a- gut which reaches to the hinder part of the body, where in a curve it turns again a little upward ; in the breaft and gut the blood is moved without intermiflion, with a great force; efpecially in the gut, where it occafions fuch a contraftion of the gut as is very furprifing. In the upper part of the crooked afcending gut above-men¬ tioned, the propelled blood (lands (till, and feems to undergo a reparation, fome of it becoming clear and waterifti, while other black particles are puflied for¬ ward to the anus. If a loufe is placed on its back, two bloody darkifh fpots appear ; the larger in the middle of the body, the lefler towards the tail; the motions of which are followed by the puliation of the dark bloody fpst, in or over which the white bladder 33 K feems PedkuLt FED [ 5922 ] FED «5. feema to lie. This motion of the fyftole and diaftole is beft feen when the creature begins to grow weak ; and on pricking the white bladder, which feems to be the heart, the creature inftantly dies. The lower dark fpot is fuppofed to be the excrement in the gut. Lice have been fuppofed to be hermaphrodites: but this is erroneous ; for Mr Lieuwenhoeck obferved, that the males have flings in their tails, which the females have not. And he fuppofes the fmarting pain, which thofe creatures fometimes give, to be owing to their flinging with thefe flings when made uneafy by pref- fure or otherwife. He fays, that he felt little or no pain from their fuckers, though fix of them were feed- iug on his hand at once. In order to know the true hiflory and manner of breeding of thefe creatures, Mr Lieuwenhoeck put two female lice into a black flocking, which he wore night and day. He found on examination that, in fix days one of them had laid above 50 eggs ; and, upon diffedling it, be found as many yet remaining in the ovary : whence he concludes, that in 12 days it would have laid too eggs. Thefe eggs naturally hatch in fix days, and would then probably have produced 50 males, and as many females; and thefe females coming to their full growth in 18 days, might each of them be fuppofed after 12 days more to lay too eggs; which eggs, in fix days more, might produce a young brood of 5000 ; fo that in eight weeks, one loufe may fee 5000 of its own defcendents. Signior Rhedi, who has more attentively obferved thefe animals than any other author, has given feveral engravings of the different fpecies of lice found on dif¬ ferent animals. Men, he obferves, are fubjedl to two kinds ; the common loufe, and the crab-loufe. He obferves alfo, that the fize of the lice is not at all pro¬ portioned to that of the animal which they infeft ; fince the darling has them as large as the fwan. Some kinds of confutations are more apt to breed lice than others; and in fome places of different de¬ grees of heat, they are certain to be deftroyed upon people who in other climates are over-run with them. It is an obfervation of Oviedp, that the Spanifh fail- ors, who are generally much afflidled with lice, always lofe them in a certain degree of latitude in their voy¬ age to the Eaft Indies, and have them again on their returning to the fame degree. This is not only true of the Spaniards, but of all other people who make the fame voyage; for though they fet out ever fo loufy, they have not one of thofe creatures by the time they come to the tropic. And in the Indies there is no fuch thing as a loufe about the body, though the people be ever fo natty. The failors continue free from thefe creatures till their return ; but in going back, they ufually begin to be loufy after they arrive at the latitude of the Madeira iflands. The extreme fweats, which the working people naturally fall into, between the latitude of Madeira and the Indies, drown and deflroy the lice ; and have the fame effedt as the rubbing over the loufy heads of children with butter and oil. The fweat, in thefe hot climates, is not rank as in Europe, and therefore it is not apt to breed lice; but where people return into latitudes where they fweat rank again, their naftinefs fubjedls them to the fame vifitations of thtfe vermin as before. The people in general in the Indies are very fubjedt to lice in then- heads, tho’ free from them on their bodies. The reafon Pcdiluvlum of this is, that their heads fweat lefs than their bodies, “ and they take no care to comb and clean them. The Spanifh negroes wafh their heads thoroughly once every week with foap, to prevent their being loufy. The makes them efcape much better than the other ne¬ groes who are flaves there; for the lice grow fo nu¬ merous in their heads, that they often eat large holes in them. PEDILUVIUM, or Bathing of the Feet. The ufes of warm bathing in general, and of the pedilu- vium in particular, are fo little underttood, that they are often prepofteroufiy ufed, and fometimes as injudi- cioufiy abftained from. In the Edinburgh medical effays, we find an in¬ genious author’s opinion of the warm pediluvium, not- withftanding that of Borelli, Boerbaave, and Hoff¬ man, to the contrary, to be, That, the legs becoming warmer than before, the blood in them is warmed : this blood rarefying, diftends the veflcls; and in circu¬ lating imparts a great degree of warmth to the rdlof the mafs ; and as there is a portion of it conllantly palling through the legs, and acquiting new heat there, which heat is in the courfe of circulation com¬ municated to the reft of the blood, the whole mafs ra¬ refying, occupies a larger fpace, and of confequence circulates with greater force. The volume of the blood being thus increafed, every velfel is diftended, and every part of the body feels the effeds of it ; the diilant parts a little later than thofe firlt heated. The benefit obtained by a warm pediluvium is generally at¬ tributed to its making a derivation into the parts im- merfed, and a revulfion from thofe affected, becaufe they are relieved ; but the cure is performed by the di- red contrary method of operating, viz. by a greater force of circulation through the parts affeded, remo¬ ving what was flagnant or moving too fluggifhly there. Warm bathing is of no ferviee where there is an irrefoluble obftrudion, though, by its taking off from a fpafm in general, it may feem to give a mo¬ ment’s cafe : nor does it draw from the dillant parts, but often hurts by pufhing^againft matter that will not yield with a (Longer impetus of circulation than the ftretched and difeafed vtfl'els can bear : fo that where there is any fufpicion of feirrhus, warm bathing of any fort Ihould never be ufed. On the other hand, where obftrudions are not of long (landing, and the impaded matter is not obftinate, warm baths may be of great ufe to refolve them quickly. In recent colds, with flight humoral peripneumonies, they are frequent¬ ly an immediate cure. This they effed by increafing the force of the circulation, opening the (kin, and dri¬ ving freely through the lungs that lentor which (lag- nated or moved flowly in them. As thus conducing to the refolution of obftrudions, they may be confi- dered as (hort and fafe fevers; and in ufing them we imitate nature, which by a fever often carries off an obftruding caufe of a chronical ailment. Borelli, Boerhaave, and Hoffman, are all of opinion, that the warm pediluvium ads by deriving a larger quantity of blood into the parts immerfed. But arguments mull give way to fads: the experiments related in the Medical Effays ftem to prove to a demonftration, that the warm pediiuvium ads by rarifying the blood. A warm gediluviutn, when rightly tempered, may be uled PEE [ 5923 ] PEE Pi'diment ufed as a fafe cordial, by which circulation can be I roufed, or a gentle fever raifed ; with this advantage .Peebles. over t^e ccr(];ais ancj fudorifics, that the effedt of thun may be taken off at pleafure. Pediltivia are fometimes ufed in the fmall-pox ; but Dr Stevenfon thinks their frequent tumultuous operations render that fufpedled, and at heft of very doubtful effed ; and he therefore prefers Monf. Mar¬ tin of Laufanne’s method of bathing the fkin, not only of the* legs, but of the whole body, with a foft cloth dipped in warm water, every four hours, til! the eruption ; by which means the pnflules may become univerfally higher, and confequently more fafe. PEDIMENT. See Architecture, n° 77. PEDLAR, a travelling foot-trader. See Haw¬ ker. Among the Britifh and French the pedlars are de- fpifed ; but it is otherwife in certain countries. In Spanilh America', the bufmefs is fo profitable, that it is thought by no means difhonourable and there are many gentlemen in Old Spain, who, when their cir- cumitances are declining, fend their fons to the In¬ dies to retrieve their fortunes in this way. Al- moft all the commodities of Europe are diftributed through the fouthern continent of America by means of thefe pedlars. They come from Panama to Pai- ta by fea ; and in the road from the port laft men¬ tioned, they make Peura their firft voyage to Li¬ ma. Some take the road through Caxamalia ; others through Truxillo, along (bore from Lima. They take their paffage back to Panama by fea, and perhaps take with them a little cargo of brandy. At Panama they again flock themfelves with European goods, return¬ ing by fea to Paita, where they are put on fliore; there they hire mules and load them, the Indians going with them in order to lead them back. Their travelling ex- pences are next to nothing; for the Indians are brought under fuch fubjedtion, that they find lodging for them, and provender for their mules, frequently thinking it an honour done them for their guefts to ac¬ cept of this for nothing, unlefs the ftranger now and then, out of generofity or compafiion, makes a fmall recompence. In Poland, where there are few or no manufa&ures, almoft all the merchandife is carried on by pedlars, who are faid to be generally Scotfmen, and who, in the reign of king Charles if. are faid to have amount¬ ed to no fewer than 53,000. PEDUNCLE, io botany. See Pedicle. PEEBLES, or Tweedale, a county of Scotland, extending 25 miles in length, and 18 in breadth. It is bounded on the eaft by Ettrick Foreft, on the fouth by Annandale, on the weft by Clydefdale, and on the north by Mid Lothian. Tweedale is a hilly country, well watered with the Tweed, the Yarrow, and a great number of {mailer dreams that fertilize the val¬ leys, which produce good harvefts of oats and barley, with fome proportion of wheat. All the rivers of any confeqnence abound with trout and falmon. The lake called Weft-Water Loch fwarms with a prodigious number of eels. In the month of Anguft, when the weft wind blows, they tumble into the river Yarrow in fuch fhoals, that the people who wade in to catch them run the rifle of being overturned. There is ano¬ ther lake on the borders of Annandale, called Loch- gentien, which forms a cataraft over a precipice 250 Peebles paces high : here the water falls with fuch a momen- turn as to kill the fifh underneath. About the middle ecf* of this country is the hill or mountain of Braidalb, from the top of which the fea may be ften on each fide of the ifland. Tweedale abounds with limeftone and freeftone. The hills are generally as green as the downs in Suffex, and feed innumerable flocks of fheep, that yield great quantities of excellent wool. The country is well fhaded with woods and plantations, abounds with all the nectffaries of life, and is adorned with many fine feats and populous villages. The earls of March were hereditary fheriffs of Tweedale, which beftows the title of marquis on a branch of the an¬ cient houfe of Hay, earls of Errol, and hereditary high conftables of Scotland. The family of Tweedale is, by the female fide, defeended from the famous Si¬ mon de Frafer, proprietor of great part of this coun¬ try, who had a great lhare in obtaining the triple vic¬ tory at Roflin. The chief, and indeed the only town of confequence in Tweedale, is Peebles, a fmall in- confiderabie royal borough, and feat of a prefbytery, pleafantly fituated on the banks of the Tweed, over which there is at this place a (lately (lone bridge of five arches. In the neighbourhood of Peebles, near the village of Romana, on the river Lene, we fee the vdliges of two Roman caftella, or ftationary forts ; and a great many terraces on the neighbouring hills, which perhaps have ferved as itinerary encampments. In the (hire of Tweedale there are many ancient and honourable families of the gentry. Among thefe, Douglas of Cavers, who was hereditary (heriff of the county, dill preferves the ftandard and the iron mace of the gallant lord Douglas, who fell in the battle of Otterburn, juft as his troops had defeated and taken Henry Percy, furnamed Hotfpur. In the church¬ yard of Drumelzier, belonging to an ancient branch of the Hay-family, the famous Merlin is fuppofed to lie buried. There was an old traditional prophecy, that the two kingdoms (hould be united, when the wa¬ ters of the Tweed and the Panfel (hould meet at his grave. Accordingly, the country people obferve that this meeting happened in confequence of an inun¬ dation at the acceffion of James VI. to the crown of England. PEEK, in the fea-language, is a word ufed in va¬ rious fenfes. Thus the anchor is faid to be a-peek, when the (hip being about to weigh comes over her anchor in fnch a manner that the cable hangs perpen¬ dicularly between the hanfe and the anchor. To have a-peek is to bring the peek fo as that the anchor may hang a-peek. A (hip is faid to ride a- peek, when lying with her main and fore yards hoift- ed up, one end of her yards is brought down to the (hrouds, and the other raifed up an end; which is chit-fly done when (he lies in rivers, left other (hips falling foul of the yards (hould break them. Riding a-broad peek, denotes much the fame, excepting that the yards are only raifed to half the height. Peek is alfo ufed for a room in the hold, extending from the bitts forward to the (lem : in this room men of war keep their powder, and merchant-men their vidluals. PEER, in general, fignifies an equal, or one of the fame rank and flation : hence in the ads of fomecoun- 33 K 2 oils, PEE [ 5924 ] PEG Peer, cils, we find thefe words, nuith the confent of our peers, ~ lijhops, abbots, &C. Afterwards the fame term was applied to the vaffals or tenants of the fame lord, who were called peers, becaufe they were all equal in con¬ dition, and obliged to ferve and attend him in his courts; and peers in fiefs, becaufe they all held fiefs of the fame lord. The term peers is now applied to thofe who are im- pannelled in an inqueft upon a perfon for convicting or acquitting him of any offence laid to his charge : and the reafon why the jury is fo called, is becaufe by the common law and the cuftom of this kingdom, every perfon is to be tried by his peers or equals; a lord by the lords, and a commoner by commoners. See the article Jury. Peer of the Realm, a noble lord who has a feat and vote in the Houfe of Lords, which is alfo called the Houfe of Peers, Thefe lords are called peers, becaufe though there is a diflindlion of degrees in our nobility, yet in public aftions they are equal, as in their votes in parliament, and in trying any nobleman or other perfon impeached by the commons, &c. See Parliament. Houfe of Peers, or Houfe of Lords, forms one of the three eftates of parliament. See Lords and Par¬ liament. In ajudicative capacity, the houfe of peers is the fupreme court of the kingdom, having at prefent no original jurifJiflion oVer caufes, but only upon appeals and writ^pf error ; to reftify any injuftice or miftake of the law committed by the courts below. To this authority they fucceeded of courfeupon the difiblution of ^he Aula Regia. For as the barons of parliament were conftituent members of that court, and the reft of its jurifdiftion was dealt out to other tribunals, over which the great officers who accompanied thofe barons were refpeftively delegated to prefide, it followed, that the right of receiving appeals, and fuperintending all other jurifdidfions, ftill remained in that noble affem- bly, from which every other great court was derived. They are therefore in all cafes the laft refort, from whofe judgment no farther appeal is permitted ; but ' every fubordinate tribunal muft conform to their de¬ terminations: The law repofing an entire confidence in the honour and confcience of the noble perfons who compofe this important afiembly, that they will make themfelves mafters of thofe quellions upon which they undertake to decide ; fince upon their decifion all pro¬ perty muft finally depend. Se,e Lords. Peers of France, are twelve great lords of that kingdom ; of which fix are dukes and fix counts ; and of thefe, fix are ecclefiaftics and fix laymen : thus the archbifhop of Rheims, and the bifhop of Laon and Langres, are dukes and peers ; and the bifhops, of Chalon on the Marn, Noyons, and Beauvais, are counts and peers. The dukes of Burgundy, Norman¬ dy, and Aquitain, are lay peers and dukes; and the counts of Flanders, Champaign, and Touloufe, lay peers and counts. Thefe peers ftill affift at the coro¬ nation of kings, either in perfon or by their repre- fentatives, where each performs the funflions attach¬ ed to his refpeedive dignity : but as the fix lay peer¬ ages are all at prefent united to the crown, except that of the count of Flanders, fix lords of the firft quality are chofen to reprrfent them : but the eccle- fiaftical peers ufually affift in perfon. At prefent the title of peer is beftowed on every lord whofe eftate is erefted into a peerage ; the number of which is uncer¬ tain, as it depends entirely on the king. PEERESS, a woman who is noble by defeent, crea¬ tion, or marriage. If a peerefs, by defeent or creation, marries a per¬ fon under the degree of nobility, (he ftill continues noble: but if ffie obtains that dignity only by mar¬ riage, (he lofes it, on her afterwards marrying a com¬ moner ; yet by the curtefy of England, fhe always re¬ tains the title of her nobility. PEWIT, in ornithology. See Larus. PEGASUS, among the poets, a horfe imagined to have wings; being that whereon Bellerophon was fabled to be mounted when he engaged the chimera. See Chimera. The opening of the fountain Hippocrene on mount Helicon, is aferibed to a blow of PegafusV hoof. It was feigned to have flown away to heaven, where it became a conftellation. Hence Pegasus, in aftronomy, the name of a conftellation of the northern hemifphere, in form of a flying horfe. See Astronomy, n° 206. PEGU, a very confiderable kingdom of Afia, be¬ yond the Ganges. The country properly fo called is but about 350 miles in length from north to fouth, and as much in breadth from eaft to weft. It is bound¬ ed, on the north by the kingdoms of Arrakan and Ava ; on the eaft, by the Upper and Lower Siam ; on the fouth, by part of Siam and the fea ; and on the weft, by the fea and part of Arrakan. Confidered in a larger fenfe however, as augmented by the con- quefts of its Barma kings, it extends as far north as the province of Yunan in China, comprehending al- moft all the farther peninfula of India. The kingdom of Pegu is.faid to have been founded about 1100 years ago. Its firft king was a feaman ; concerning whom and his fucceffors we know nothing till the difeovery of the Eaft Indies by the Portuguefe in the beginning of the 16th century. In 1518 the throne of Pegu was poffefled by-one Breflagukan, with whom Antony Correa the Portuguefe ambaffador folemnly concluded a peace in 1519. This monarch was poflefied of a very large and rich empire, nine kingdoms being in fubje&ion to him, whofe revenues amounted to three millions of gold. We hear no far¬ ther account of his franfadions after the conclufion of the treaty with the Portuguefe. In 1539 he was mur¬ dered on the following occafion : Among other prin¬ ces who were his tributaries was Para Mandera, king of the Barmas. Thefe people inhabited the high lands called Pangavirau, to the northward of the kingdom of Pegu. Their prince, by one of the terms of his vaffalage, was obliged
