In completing a work which has formed my principal occupation for more than twenty years, it is not the least of my gratifications, that it affords me an opportunity of adorning it with a name which will occupy a proud sta- tion in the intellectual annals of our country. It has been the lot of few to combine the capacities of a statesman with the highest acquirements in science and literature, and of fewer still to become the founder of Institutions, for dilfusing the blessings of knowledge, and advancing the great interests of public education. But even to these objects your powers have not been limited. There is no public measure, whether of science, of humanity, or of patriotism, which has not been sustained by your strength, and recommended by your elo- quence ; and such has been the triumph of your labours, that even those who regarded the diffusion of knowledge with fear, and the amelioration of our Institutions with alarm, are now struggling for the accomplishment of these great objects, and striving to weave a chaplet from your ungathered laurels. B* 1.1.4o349 IV A work, therefore, like the present, in which all the great questions of civil and religious liberty have been advocated, in which the unalienable rights of humanity have been pled, and in which the sound doctrines of our faith have been established and expounded, has some right to the shelter of a name associated with the maintenance of these bulwarks of the consti- tution. In addition to these public motives for dedicating to you this Work, I may well add those of a personal nature, which spring from a deep sense of your kindness and friendship ; and while I thus express to you my gratitude for the flattering interest you have taken in the scientific pursuits of my riper years, I may be permitted to remind you of those early days, when educated in the same university, and taught by the same distinguished master, we began our scientific labours by the independent investigation of the same properties of light. The ardour of your pursuit often stimulated mine, and if the success of our inquiries was not proportional to the zeal with which they were prosecuted, it must be remembered, that the subject was one where Newton failed, and which required for developement the lights of an- other century. DAVID BREWSTER. Allerly, /unc 1, 1830. PREFACE W^UEN the Edinburgh Encyclopedia was first projected, the Proprietors were anxious to distinguish it by two features which had not been exhibited in any similar work published in England, namely, by the Originality and the Selectness of its articles. They were aware that those who considered an Encyclopaedia as a Dictionary in which every thing should be explained and described, whether it was insignificant or important, might be disappointed by the numerous omissions which such a plan rendered necessary ; but they felt that it was only by carrying it completely into effect, that they could render their work a Dictionary of really use- ful knowledge. The original composition of the articles, by persons well acquainted with the subjects which they undertook, ensured, to a certain degree the condensa- tion of materials, and the introduction of the last information and discoveries : while the rejection of innumerable subjects which found a place in other works, enabled the Editor to give to the leading treatises nearly twice the space which they usually occupied. The popularity of this plan of conducting an Encyclopsedia was evinced by the unexampled success of the work. The early numbers of it went through va- rious editions, and the shares of the property were sold at a very high premium. This great success, while it encouraged the Proprietors to spare no expense in the embellishments of the work, naturally led them to the opinion that the limits of VI PREFACE. TWEi.VE volumes, which they had at first prescribed to themselves, were too confined to give full effect to their arrangements ; and when they found this opinion confirm- ed by numerous representations from the Subscribers themselves, they did not scruple to extend the work to kiguteen volumes. The great delay which has taken place in bringing the Edinburgh Encyclopedia to a close, has been a source of serious vexation to the Editor and Proprietors. In the early stages of the work, this delay arose in those mechanical departments of it over which the editor had no control, and to a certain degree from the reprinting of the earlier parts ; but it has been principally owing to the indolence, the ill health, and the deaths of Contributors. In an undertaking in which more than one hundred and fifty Contributors were engaged, such delays were not only frequent in their occurrence, but long in their duration ; and the Editor has been sometimes com- pelled to wait more than six months for the manuscript of articles which had been engaged several years before, and which he had allowed to remain in the hands of their authors for the sole purpose of receiving the latest improvements. At other times the Editor was compelled to reject articles that were unsuitable to the work ; and it was frequently necessary to re-transmit them to their authors for the purpose of being altered or condensed. In justice, however, to some of the gentlemen here referred to, it ought to be stated, that the delay in completing their articles, arose from the great difficulty which they experienced in procuring the requisite materials, and from an excessive anxiety to make their labour worthy of the public approbation. The Editor is far from claiming an immunity from the human infir- mities he has ascribed to his contributors ; but he flatters himself that few of the Subscribers will impute the delay of the publication to any voluntary omission of his, when they are informed that his remuneration, which was not by a salary, but a specific allowance on the appearance of each volume, was retarded and diminish- ed by any stoppage in the publication. But whatever were the causes of the delay in the completion of the Work, it has, like every other evil, been accompanied with many advantages. Had the work PREFACE. VII been completed at the time originally contemplated, it must have been deprived of many of the best articles which it contains, written by Individuals of the most distinguished eminence in science and literature. The return of peace to Europe gave a vigorous impulse to scientific inquiry ; and new sciences were created which were not even known by name at the commencementof the work. Two of these, namely, the Polauisation of Light,* and Electromagnetism,! have been fully treated in the latter volumes of the work, the last of these articles having been written by Professor Oersted, the distinguished philosopher to whom that science owes it existence. The History of Europe, too, has thus been brought down to the termination of the war between Russia and Turkey, and embraces the fullest details respecting the most eventful period of the History of our species. From the same cause the Editor has been able to enrich the last vohimes of the work with the results of the various Voyages of Discovery performed at the expense of the British Government, and even of the latest Journey into Siberia, performed in 1829 by Professor Hansteen, for the purpose of exploring the distribution of tlie earth's magnetism. J But notwithstanding these exertions to supply, under the later articles of the work, the deficiences which necessarily existed in the earlier portions of it, it is impossible to deny, that there are still some imprefections to be rectified, and many defects to be supplied. Inventions and speculations, which seem to be insignifi- cant at one period, rise into importance in the progress of inquiry, and the names of individuals, at one time obscure, frequently derive a new lustre from the genius of those who carry on and perfect their labours. But, independent of these causes, the interval of twenty years which has elapsed between the commencement and the * See Optics, Part I. Chap. VI. and VII. ■f'See our Article Thebmo-Electricity, under which the Science of Electro-magnetism is given. J See Polar Regions, and variation of the Needle. VIU PREFACE. completion of the Encyclopaedia, has unavoidably given birth to important events, and been marked by many discoveries and inventions, which it was impossible to introduce under an alphabetical arrangement. The History of the New Govern- ments of South America — the domestic History of Great Britain, France, and other States, and the numerous and splendid discoveries which have extended the boundaries of Chemistry, Mineralogy, and every branch both of Natural History and Natural Philosophy, are still wanting to accommodate the work to the present state of our knowledge. With a view to supply these defects, not only in the work now offered to the public, but in all others of a similar description, the Editor has projected, and part- ly prepared, a Supplementary Publication, in which he proposes, in the compass of two such Volumes as the present, to bring down the History of Science from about the year 1810 to the present day- For this arduous undertaking he flatters himself that he has been in some measure qualified and prepaired by his long experience, not only as the Editor of this Encyclopaedia, but as the conductor of a Scietific Journal.

A IS the first letter of the alphabet in almost all 5 languages, and has probably received this place from tlie facility with which wc utter the sound that it represents. In pronouncing this letter, the lips assume no particular position, but are merely opened to form a passage' for the voice.* See Alphabet. The Letter A is also a mark of abbreviation, and re- presents a great number of words, which will be foimd under the article Character. A is likewise a word, and is sometimes the indefinite article, and sometimes a preposition. When it is used as an article, it is prefixed to a singular noun, in order to separate one individual from the Genus or general class, of which the noim is the common name. Its sig- nification, indeed, is nearly the same with the word one, and in the French and Italian languages, the numeri- cal words itri, uno, are also the indefinite articles. Al- though the indefinite article denotes only a single indi- vidual of a genus, yet it is sometimes prefixed to plural nouns, as o./c-rv, n hundred. Tliese plural words, how- ever, denote a number of individuals taken collectively, and therefore to this aggregate, or whole, the indefinite article is still applied. See Grammar. The letter A seems to be a preposition in the expres- sions, " I wenta-hunting," " Thomas a-Kempis," o-loft, «-hcad, a-foot. In these cases Dr Wallace considers it as a contraction of a^.f But as at has a relation chief- ly to place, Dr Lowth^ regards the word « as a substi- tute for the preposition on. Dr Johnson, and all other writers, suppose the word * In the English language, it has a more acute sound, than in any other European idiom. When long and ac- cented, it is sounded like the diphthong ai. DuroN- CEAU. t It is not so, however, in Thomas c-Kempis, and other similar Latinized names of the middle ages, in which a, the preposition of the Latin ablative, stands for the Eng- lish preposition of. Tims, Thomas a-Kempis, means Thomas of Kempis. /(/. t And Mr Home Tooke. Id. Vol. I. Part I. a to have a peculiar signification in the phrases " ten pounds a-year," " two hours a-day ;" but it is evident, that in these expressions it is nothing more than the in- definite article, signifying one, as " ten pounds one year," " two hours one day." A, in music, is the nominal of the sixth note in the natural diatonic scale, or gamut; to which Guido Arc- tino originally applied the monosyllable la. It is like- wise the name of one of the two natural moods ; and is the open note of the second string of the violin, by which its other strings are tuned and regulated. A is like- wise the name of that note in our system which cor- responds with the lowest sound employed by the ancient Greeks ; i. e. the irfoo-A«(«,/3«»ott£vo5 of the hyperdorian, or deepest Greek mode, placed by the moderns on the first space in the bass-cliff. If any numeral figure is added to the letter A, when prefixed to a vocal compo- sition, it denotes the number of voices for which the piece is intended ; thus A 3 signifies for three voices.

It lies on the ca- nal which joins the gulf of Lymfurl and the sea, and de- rives itsuame from the number of eels which arc caught in the neighbourhood, the word signifying Eel-town. The city is large, containing 14,500 inhabitaiits, and, ex- cepting Copenhagen, is the richest and finest city in Denmark. It has an exchange for merchants, an excel- lent harbour, a considerable trade in corn and herring, and different manufactories of guns, pistols, saddles, and gloves. It was taken by the Swedes in 1643, and 1558. The diocese forms the northern extremity of Jutland, and the greater part of it lies in a peninsula made by the sea and the gulf of Lymfurt.

When Moses was commissioned by heaven to release his countrymen from the yoke of the Egyptians, Aaron, who was more eloquent than his bro- ther, was appointed his interpreter. Some time after the deliverance of the Israelites, he and his sons were invested with the sacerdotal office, which was to be transmitted to their descendants in perpetual succes- sion. His facility in yielding to the murmurs of the people, while Moses was receiving the law on Mount Sinai, and making a golden calf, in compliance with their idolatrous desires, was keenly resented by his bro- ther, who would probably have deprived him of the sa- cred character, which he had thus violated, had he not atoned for his transgression by humility and repentance. He does not seem, however, to have ever attained the strong and immoveable faith which distinguished the leader of Israel. On account of his vinbelief at Kadish, he was prevented from entering the promised land, and died in the 14jd year of his age, forty years after the emigration of the Israelites from Egypt. He was bu- ried by his son and Moses in a cave of the iiiountain Hor. See Univ.

The fruit is of the size of a hen's egg, and is included with several more in a large shell. In the middle of the fruit there is a hard nut, abotitthe size of a peach stone, which contains a nu- cleus resembling a white almond. This nucleus is mild and nutritive, and is employed by the natives as an as- tringent, particularly in cases of diarrhoea. The pulp, which incircles the kernel, is eaten by cows and other quadrupeds, and, when macerated, affords an oil which is fit for burning, and useful as a condiment. The tree has been transplanted to Guiana, and is frequently con- founded with the cocoa-nut tree. See La Marck's Illus- trations of Xatural History, Plate 896.

The month Ab contained 30 days, and comprehended part of our months of July and August, or, according to some writers, of June and July. The ninth day of thismontli was observed as a fast by the Jews, to commemorate the destruction of the tem- ple by Nebuchadnezzar. It is remarkable, that this event happened on the same day of the year on which the temple was afterwards burned by Titus, and on which Adrian published his edict for prohibiting the Jews from continuing in Judea.

(o) AB ACINARE, from the Italian abbacinare, to dazzle, or make blind, from the root bacino, a basin, is the name of a punishment, in which the criminal was deprived of sight, by holding to his eyes a red-hot basin, made of iron or brass. It appears from Plato, (in Gorgia,) and from Labcrius, (apud Jul. Gelt. lib. iv. c. 17.) thai this punishment was very ancient. Robert, duke of Nor- mandy, suffered this punishment from Henry I. of Eng- land. The operation was performed ficlvi cattcUnte et valdc igmsceyitc ajiftosita. Languis in Chron. A. C. 1 102.

(t) ABACK, in Naval Tactics, is the situation of the sails of a ship, when they are flattened against the masts by the impulse of the wind. The sails may be brought aback, either by a sudden change in the w ind, or by an altera- tion in the course of the ship. By slackening the lee- braces, and hauling in the weather ones, so that the whole impulse of the wind may be exerted on the fore-part of the sails, they are laid aback, either for the purpose of retreating without turning to one side, when the ship is in danger in a narrow channel, or when she has advanced beyond her station in the line of battle, (o) ABACUS, from the synonymous Greek word «/3a|, or from the Phenician word abek, dust, is the name of a smooth table covered with dust, on which the first ma- thematicians made their calculations, and traced their diagrams. See Prrsius, Sat. 1. v. 131. Hence it be- came the appellation of an instrument employed by tlic ancients for perfomiing the operations of aritlimetic. The abacus generally used, is represented in the an- nexed diagram, and consists of any number of parallel lines drawn at a distance from each other, equal to twice the diameter of a counter. A counter placed on the first -o- -o- -o- 10,000 1,000 100 10 1 o O O O— or uppermost line signifies 10,000; and two counters, 2x10,000 or 20,000. A counter on the second line, sig- nifies 1000; a counter on the third line, 100; on the fourth line, 10; and, on the fifth, 1. When a counter is placed in any of the spaces between the parallel lines, it signifies one halfof what it would signify if it were placed in the line immediately above it; or five times what it would signify if it were placed on the line immediately below it. In the space between the second and third lines, for example, each counter signifies 500. In the annexed abacus, therefore, the counters on the first line will denote 40,000 ; those on the second, 3,000 ; those which lie between the second and third, 1,000 ; those on the third line, 300 ; that which lies between the third and fourth, 50 ; those on the fourth, 20 ; and those on the fifth, 4. The whole sum, consequently, which the counters in- dicate, will be 40,000 3,000 1,000 300 50 20 44,374 ABACUS. Instead of the parallel lines and counters, brass wires and ivory balls are frequently substituted. See Hist. Acad, hiscrijit. torn. iii. p. 390. Wolfii Lcxk. Malhemat. p. 171. Phil. Trans. No. 180. An ingenious abacus, invented by the celebrated Par- rault, is represented in Plate I. fig. 1. It consists of two plates, PQRS, ABCD ; of which ABCD is the upper- most, and is placed directly above PQRS. The plate PQRS is about an inch thick, and a foot long, and has a numberof grooves, in which the slips of ivory, or copper, kg., lf,Jic, ijd, kc. are moveable in either direction, like the sliding lid of a box. Each slip is divided into 26 cqvial parts, by horizontal lines cut pretty deep, and has a figure in every division, except the four middle ones, as appears from the plate. The uppermost plate, ABCD, is pierced completely through by the two openings EF, GH, each being exactly opposite the line of ci- phers, and also by the seven vertical openings, m«, o/i, &c. When the slips of ivory are raised or depressed, the figures will appear in the openings EF, GH, but in such a manner, that the sum of the two figures on the same slip, which appear in the openings EF, GH, will always amount to 10. This slip at N, contains U72its ; the slip at U, tens ; the slip at C, httndi\-ds, &c. In order to move the slips, when the plate ABCD is placed upon the plate PQRS, a sharp point is introduced through the grooves mn, o/i, kc. and placed in one of the cross strokes in the slips of ivory, so that, by a slight oblique pressure, the slip may be either raised or depressed. When any par- ticular figure is wanted in the opening GH, we have on- ly to place the sharp point in the cross stroke of the slip that appears through the grooves mw, o/i, opposite to the figure required, and then move the slip downwards, till the sharp point is at ?z, ovfi, or the bottom of the groove, the required figure will appear in the opening GH. The reason of this may be readily understood by inspecting the figure. The pieces of wood, between which the slips of ivory move, are interrupted in their length by a space equal to three of the spaces in the slips, as is represented by the shaded parts above g;/, c, Sec. and the middle of each interruption ought to be exactly opposite the opening GH. The lower surface of each slip of ivory, as T-T, is formed into teeth L, L, each tooth being opposite one of the 1 1 figures, and carries a catch M, with a spring N. By pressing against M, the catch may be made to lie within the slip T-T ; but when the pressure is removed, the spring N forces it out, as in the figure. Now, when the slip is moving in its groove the catch M will be kept within the slip by the pressure of one of the pieces of wood between which it moves, till the catch comes op- posite to the interruption in the piece of wood, when the spring will force it out, so that it will enter into the teeth of the adjacent slip on the left hand, and carry it down one space. In order to show the use of this Abacus, let us sup- pose it required to add 8 to 7. In the groove m?z of units, place the sharp point upon the cross stroke of the ivory slip opposite 8, and pressing with the sharp point till it comes to n, the number 8 will appear in the line of units to the left hand of H. When this is done, place the sharp point in the cross stroke opposite 7, and bring it also down to n. Instead of 7, a will appear in the line of units at H, and a 1 in the line of hundreds, as the slip which contains the line of hun- dreds has been brought down one space by the catch in the slip of units. Keeping the sharp point still at «, in the stroke which was opposite 7, moye the slip up- wards till the point reaches liie very top m, and a 5 will now appear in place of 0, in the line of units at H ; so that the figures in the opening GH will be now 15, the sum of 7 and 8. Whenever a blank space or a ap- pears in the opening, the slips of ivory must always be carried up to the very top of the groove. In subtraction, we must put the greaternumber, sup- pose 123, in the opening EF, and if the lesser number be 34, we must, by means of the sharp point placed in the cross stroke opposite 4, bring this figure in the line of units to the bottom of the groove mn, and also the figure 3 in the line of tens, to the bottom of the groove o/i. Instead of the number 123 in the opening EF, wc shall now have 89, the difference between 123 and 34. It must be attended to, however, that whenever there is a in the greater number, we must take 1 from the line of tens, if the is in the Hne oi units, and 1 from the line of hundreds, if the is in the Une of tens : Thus, if we want the difference between 92 and 150, the Aba- cus will give 68 instead of 58 ; and if we want the dif- ference between 1500 and 264, the Abacus will give 1346 instead of 1236. In multiplication, the same process is necessary as in addition. If, for example, the product of 15 and 15 were required, wc bring 5 times 5, which is 25, into the lower opening, by means of tlie sharp point, as before, and we afterwards bring one times 5, or 5, in the line of tens, to the opening; and one times i, or I, in the line of hundreds, to the opening. When this is done, the number 225 will appear in the opening, as the product of 15 by 15. In the figure, we have, for the sake of distinctness, represented only one of the slips with teeth and a catch ; but all the slips, except the last kg, have a catch ; and all of tliem, except the first ta, have teeth.

(to) ABACUS, in Architecture, is the highest part of the capital of a column, or pilaster.* According to Vitruvius, the Abacus originally re- presented a square tile placed over a basket. An Athe- nian woman happening to place a basket, with a tile over it, above the root of an acanthus, the plant vege- tated and incircled the basket, till, meeting with the tile, it curled back, and twisted itself into the form of a volute. The sculptor Callimachus passing by, is said to have taken the hint, and invented the Corinthian ca- pital. See Civil jirchitecture.

According to D.apper, it has two horns of different sizes ; one on its forehead, and the other in the nape of its neck. Its head and tail resemble those of an ox, and its feet arc like those of a stag. The horn on its forehead is considered by the negroes as a specific in several diseases. Vallisneri has adopted the description given by Dapper as be- longing to a real animal ; but Cuvicr is of opinion, that * That part of the capital of a column which sur- mounts the circular part of the same, and which is square.

Some authors suppose him to be Satan ; and the locusts to be zealots, or robbers infest- ing the land of Judea. Others think that it was Maho- met who issued from the abyss, or the cave of Hera ; and Mr Bryant imagines it to be the name of the Ophite, or Serpent Deity, anciently worshipped. See Lowman's Parajthrase on the Revelations, p. 1 19. More's Theological Works, p. 130. (c) ABANO, or Apono, (Peter de) one of the most celebrated philosophers and physicians of his age, was born in the year 1250, at Abano, a village in the neigh- bourhood of Padua, from which he received his name. After studying Greek at Constantinople, to which he went at an early age, he repaired to Paris, where he was itistructed m the science of mathematics, and took his degree of medicine and philosophy. His thirst for knowledge seems also to have prompted him to travel into England and Scotland, which he is said to have visited before he returned to his native country. In the year 1302, he was appointed professor of medicine in the university of Padua ; but tJiough this office was created for himself, he soon relinquished it, and went to practise physic at Bologna. His reputation as a phy- sician was so great, that, for every visit to his patients, who resided without the walls of Bologna, he received the sum of 50 florins ; and when he was called to Rome to attend pope Honorius the Fourth, he demanded 400 ducats a-day for his trouble. The science of astrology seems to have been a fa- vourite study of Abano's. He wrote no less than three works upon this subject ; and we lind him predicting the effects of his medicines, and the fate of his patients, from the aspect and position of the stars. Hence he was regarded as a magician by the vulgar, and was sup- posed to have acquired his knowledge of the seven li- beral arts, under the tuition of seven familiar spirits, whom lie kept imprisoned in a crystal vase. With such superior pretensions to knowledge, Abano could not long escape the notice of the inquisition. He was accused of denying the existence of demons and spi- rits ; and, in 1306, through the malice of a rival phy- sician, he was denounced before the inquisitorial tribu- nal as guilty of necromancy and divination. By the powerful influence of his friends, the severity of his judges was softened, and he was acquitted of the charges which malevolence had preferred. This disappoint- ment, however, did not extinguish the hostility ol his en- emies : the philosophical studies, and the liberal senti- ments of .\bano, supplied them with fresh sources of accusation ; and as if the crime of necromancy had not appeared sufficiently heinous, thev preferred the more popular and destructive charges of heresy and atheism. Again dragged before the inquisition, and anticipating, probably, the issue of his trial, the health and spirits of Abano began to decline, and death rescued him from the grasp of his enemies in 1315, at the age of sixty-six. But even deadi did not disarm the malignant fury of his persectitors. The holy inquisitors sat in judgment on his lifeless corpse ; and, as if the spirit that had fled from its cold tenement had been sensible to suffering, they condemned the body to be consigned to the flames ; and threatened, with excommunication, the magistrates of Padua, unless they put in execution the baibarous- sentence. The body of Abano, however, had been rais- ed by an affectionate domestic from its place of inter- ment in tlic church of St Anthony, and concealed in a sepulchre that happened to be open in the church of St Peter. When the inquisitors found that the body had been carried off, they threatened vengeance against eve- ry person concerned in the transaction : but the magis- trates of I'adua opposed this barbarous excess of rigour ; and the inquisition was satisfied with the impotent pa- rade of burning Abaiw in effigy in the market-place of Padua. The corpse was afterwards transferred to the church of St Augustine ; where a sepulchral stone still marks the spot in which the persecuted body of Abano was at length suffered to repose. While Abano remained at Paris, he composed his principal work, intitled, Conciliator diffvrcntiarum Phi- losojihorum et firecijiue JMcdicoriun, which was first pub- lished at Venice in 1471. It was reprinted at Mantua in 1472, and though it has passed through many editions it is now very scarce. His other works are, 1. De Venenis eorumijue remediis, Mantua, 1472. 2.

(^) ABANTES, a warlike people, who emigrated from Thrace into Phocis, a Grecian province, where they founded a city, and called it Aba, after the name of their leader. They afterwards went to Euboea, an island on the eastern coast of Greece, which was tlience call- ed Abantias, or Abantis. The Abantes were a brave people, and always came to close combat with their enemies. They wore their hair long behind, but had it cut short before, in order to prevent it from being seized by their adversaries in battle.

The period when he flourished is extremely doubtful, (Bishop Lloyd's Chronological Account of Pijthagoras, v. 7.) and his ABA ABB history is so completely involved in fables, that Hero- dotus himself did not venture to record them. This historian contents himself with relating; the story of his carrying an arrow through the world, and living with- out any sustenance, (Lib. iv. cap. 36. p. 296. edit. Wes- selingii.) Herodotus, it would appear, was unacquainted with the most marvellous parts of the story ; for Jam- blichus, who pretends to better information, affirms, that, upon this arrow, which Abaris had received from the Hyperborean Apollo, he was conveyed through the air, like a witch on a broom-stick. (Ki/a Pythagorx, p. 128.) At an advanced age, his countrymen sent him to Athens, in the character of an ambassador (Harpocra- tionis Dictionariu/n in decern liheiurcs, voce aCu^h.); and, according to Strabo, (tom. i. p. 462) he recommended himself by his politeness, eloquence, and wisdom, to the esteem of the learned men of Greece. Having traver- sed various countries, he returned home, in order to consecrate the gold, which he had collected, to the Hyperborean Apollo ; lor he was one of the priests of this divinity. In his progress, he is reported, by Porphyry and Jamblichus,to have visited Pythagoras in Italy ; and to have been favoured with a sight of his golden thigh. That he was contemporary with this philosopher, is very far from being certain ; but he at least appears to have been as great an impostor as him- self. Some of the ancients considered him as a conjurer ; others with greater justice, as a mere cheat. Suidas mentions him as the author of various works. Mr Toland supposes Abaris to have been a druid, and a native of the Hebrides. (Post/iumous iror/cs,\o\.i. p. 161.) The same strange hypothesis has been adopted by the in- dustrious Mr Carte {Hist, of Ktigland, vol. i. p. 52.); but it involves so many absurdities, that it seems hardly intitled to a serious refutation. We shall only oppose it by asking a single question. Himerius, the sophist, (a/iud Photium, p. 1136.) extols Abaris for speaking- pure Greek, which he is said to have acquired by means of the intercourse between the Greeks and Hyper- boreans. Did such a frequent intercourse subsist many hundred years before Christ, between the inhabitants of Greece and the Hebrides ? The most curious account of Abaris is to be found in Bayle's Dictionnaire His- lorique et Cricitjue. See also Bruckeri Historia Crilica Philosofihiie.

The women arc remarkably beautiful, and the men active and robust.

To avoid the persecutions to which Protestants were then exposed, his mother carried him into Switzerland, after the decease of his lather, where he prosecuted the studies of physic and theology. He visited Holland in 1698, and became acquainted with some of the eminent literati of that period, such ah Bayle, Jurieu,and Basnagc. He then visited England, and was introduced to sir Isaac Newton, with whom he afterwards entered into an epistolary correspondence. The intimacy of Abauzit with this illustrious philoso- pher, was owing to his defence of Newton against Cas- t^l, and to his having detected an error in the Princi/iici. King William HI. invited him to settle in England ; but this offer he declined. In 1723, he refused the profes- sorship of philosophy in Geneva; but was, in 1726, ad- mitted a citizen, and appointed librarian of that cit) . Here his learning, piety, and simplicity of manners, ac- quired him the estimation of his fellow-citizens, who deeply regretted his death, which happened on the 20th March 1767. '' Abauzit was the author of some mathematical works, defending the doctrines of Newton ; and also of several theological tracts. From his desire to divest the scrip- tures of mysteries, he employed himself in discovering what he supposed errors in the different translations. He wrote an essay on the Apocalypse, endeavouring to demonstrate, that the predictions there contained were applicable to the destruction of Jerusalem. But, in con- sequence of a translation of this work into English, to which a satisfactory refutation was added, he suppres- sed a new edition, which was then prepared for the press. Abauzit was honoured with the friendship and esteem of Voltaire and Rousseau, the latter of whom ad- dressed to Abauzit a handsome eloge in the highest strain of panegyric, (c) ABBADIE, James, a Protestant divine of eminence, born at Nay, in Berne, between 1650 and 1660. He went into Holland, Germany, and Prussia, and was ap- pointed minister of the French church in Berlin. He came into England with the prince of Orange ; and, af- ter being appointed minister of the French church ui the Savoy in London, he was promoted to the deanery of Killaloe, in Ireland. His discourses, in the pulpit, were admired as the finest specimens of eloquence ; and his memory is said to have been So great, that he com- posed all his works before they were committed to wri- ting. He died in 1727. Besides theological works, he published a defence of the Revolution, and a panegyric on Mary, queen of England, printed at the Hague, 1695. (c) ABBE , the name of a class of persons in France, who have not obtained a fixed settlement, cither, in church or state. They were not in orders, but, having undergone the ceremony of tonsure, were intitled to certain privileges in the church. Their dress is ra- ther academical than ecclesiastical ; and they are gene- rally employed as tutors in colleges and private fami- lies. Many individuals of this order liave been among the brightest ornaments of science and literature, (to) ABBESS, the superior of a nunnery, or, more par- ticularly, a nun invested with an abbacy. By the coun- cil of Trent, it was decreed, that an abbess must be at least forty years of age ; and that she should receive the veil of prelacy at the age of sixty. She is elected from the sisterhood of her own order ; and, after her election is read aloud, she prostrates herself on the carpet, before the great altar, and the sisters begin the ABB ABB litany. The bishop of the diocese then delivers to her the pastoral staff, will) these words: — "Receive this pastoral staff ; to be borne before the flock, committed to your charge, as a warning ol' just severity and cor- rection." The power of an abbess, over her convent, resembles that cl' an abbot ; but she does not perform the spiritual functions. Formerly some were accus- tomed to give the veil to nuns ; but this was after- wards judged unlawful. It was also usual for the ab- besses to confess ; but, it is said, that their curiosity led them to such an extent, that it was necessary to check that practice. The presence of the abbess, during ccql fcssion is allowed by St Basil. In France and Italy, many were exempted from Episcopal Jurisdiction, and some had the privilege of commissioning a priest to act for thenl in performing the spiritual functions.

(c) ABBEVILLE, a large town m France, in the depart- ment of the Sommc. It is pleasantly situated in a fer- tile valley, where the river Somme separates itself into several branches, and divides the town into two parts. The town is fortified, and the walls are flanked with bastions, and incircled with wide ditches. From the circumstances of its never having been taken, it is call- ed the Maiden Town, and assumes the motto of semper Jidelis. The woollen manufactory, which was establish- ed here in 1 665, under the auspices of Colbert, has pro- duced stuffs little inferior to those of England and Hol- land ; but tliC success of this manufactory has been part- ly owing to the clandestine importation of English and Irish wool, and to the mgenuity of British workmen. By means of the Spmnie, in which the tide rises about six or seven feet, the inhabitants carry on a considera- ble trade in grain, hemp, flax, sail-cloth, coarse linens, cordage, oil, and black and green soap. The town, which is rather of a mean appearance, contains 18,052 inhabitants, and the two cantons, 22,004. Its territory comprehends 107| kiliometres, and 13 communes. It has a collegiate church, and 13 parish churches, with a number of monasteries and nunneries. Its distance from Paris is 45 French leagues N. W. its Long. 1° 49' 45" E. and Lat. 50° 7' 1" k. See L' Histoire Gene- alogique des Comfites de Ponthieu. Paris, 1657. (o) ABBEY, a religious house, governed by an abbot, or abbess. In Britain, religious houses were of various denominations, such as abbeys, priories, and hospitals ; and differed chiefly in the extent of their possessions, powers and privileges. At first, the endowments of abbeys were probably but of limited extent ; but they afterwards acquired immense tracts of territory, pur- chased either by means of their own treasures, or ob- tained I)y pious donations from otliers; given under the condition of burning a taper on the tomb of the donor, or of celebrating solemn masses for the repose of his soul. The property, thus bestowed, could not return to the laity ; as many canons prohibited the alienation of the property of the church. Certain statutes are therefore said to have been enacted against these gifts in mortmain; and, in several grants to laymen, the grantees were prohibited from selling to monks, and particularly to Jews. From simple places of retirement, where the devout withdrew to the exercise of religious meditation, abbeys, by the gradual accession of riches, were at length converted into palaces ; luxuiy was in- troduced, and, along with it, dissipation and vice. The gjrogrcss of the Protestant religion gradually under- mined the Catholic superstition. The populace beheld their possessions with a jealous eye, wliilc they could discover no indications of any charitable jjurpose to which they were applied. The Catholics in England were nearly rooted out in the reign of Henry VIII., and those in Scotland a few years afterwards ; and their possessions were siczcd upon by the crown, or by those subjects who had influence to obtain a share for them- selves. At this day, their property is either in the hands of the crown, or held by private individuals. Certahi abbeys enjoyed extraordinary privileges. They were allowed to coin money; and an extensive jurisdiction was conferred upon them, in virtue of which, the abbot, by his deputy, could even try offen- ders for capital crimes committed within the territories of the abbey. Some could export every thing pro- duced within their bounds, free ot duty ; while others were exempted from the power of the bishop of the diocese. Several abbeys obtained bulls from the pope, declaring, that they should he liable for no debts, unless it were proved, that the money borrowed was expressly converted to the use of the community. The abbots, who ruled many of the abbeys in Britain, had the privi- leges of lords of parliament. Tweniy-nhie are enume- rated, who, in England, had a seat in the House of Lords; but this honour was taken from the order in 1540. In nunneries, subservient to abbeys, the abbot could elect the superior. There were many offices in abbeys, besides that held by the abbot ; such as that of prior, sub-prior, chamber- lain, treasvu'er, almoner. Sec; aid the duties oi these persons were all regulated with the greatest punctuali- ty. There was likewise a master of the novices, whose province it was to instruct them in the rules of their order ; and, by the Benedictine constitutions, a master was to be provided for teaching granmiar, logic, and philosophy. There were also lay teachers ; and monks themselves sometimes travelled from house to house, giving instructions in music and singing Monasteries were the sole abode of the sciences cul- tivated in ancient times. We are indebted to monks alone, for the histories of our forefathers, which have been transmitted to the present day ; and we cannot sufficiently regret the destruction of their libraries, which fell a sacrifice to the religious zeal of the reform- ers, as there were no other places that, for succes- sive ages, had been a secure deposit for historical re- cords, and the learning of antiquity. Hence, though we may hail the overthrow of popery in these king- doms, as an event which cannot be too highly prized, we must lament the losses which literature has sustained in the general devastation. Besides the library, there was in the abbey a writing-room ; and it is well kno\^Ti, that the most beautiful manuscripts now existing were writ- ten by monks ; some of which, of immense extent, are adorned with such splendid illuminations, and written with so much care, that it would seem to have required, almost a lifetime for their execution. Monasteries afforded a welcome asylum to those who wished to forsake the active toils of life, and a tranquil retreat to persons of dignified birth, in indigence or old age. They supported the poor, received pilgrims, and afforded entertainment to travellers. Perhaps it may be the subject of just regret, that Uiere are at this day no institutions of a similar nature in Britain, which might afford a secure retixat to persons, parti- Mb OT. cularly females, whom fortuitous events have prevented from holding their proper place in society. See Mo- NASTEIIV. (f) ABBOT, tiie superior of an abbey of monks, and next in dignity to a bishop. This ai)pcllution, signify- ing fatlicr, is derived from the Hebrew, and was an- ciently applied to all monks. The rulers of the early monasteries assumed the title of Abbot, or Archiman- drite. Some of the ancient French peers, and even several of their sovereigns, are mentioned in history under the denomination of Abbots ; probably from en- joying particular possessions, similar to the ecclesias- tical principalities of modern times. Anciently, abbots were subject to the bishops, or or- dinary pastors, and took no share in ecclesiastical af- fairs, because their dwellings were in remote places. But their manners soon changed : They gradually be- gan to usurp power; they aspired to tlie rank of pre- lates, and aimed at independence of the bishops, in which many of them succeeded. Abbots, intitled to wear the episcopal badges, such as the mitre or ring, or exercise episcopal authority, were denominated mitred abbots. Others, from bearing the pastoral staff only, were called crosiered abbots ; others, ecumenical abbots; and some, from their supe- riority over all others, were styled cardinal abbots. In the Roman Catholic countries, rcg-Kfa;- abbots are those who take the vows and wear the habit of the order: commendatory abbots, on the other hand are seculars, who have received tonsure, but must take orders at a certain age. In Britain, the abbot was an ecclesiastic of great power and dignity : When visiting a monastery, he was received by a procession of monks ; and he could confine those of his own monastery in a strong prison, called the " lying house," appropriated for great of- fenders. Monks, after liaving been beaten even to a plentiful effusion of blood, have by his order been con- fined in that dungeon. Much ceremony was used at tlie election and bene- diction of an abbot, and gorgeous feasts were given at their installation. Their public dress was the Dalmatic or seamless coat of Christ, the mitre, crosier, gloves, ring, and sandals ; and those in parliament wore an elegant robe. At an abbot's decease, his seals were broken on one of the steps before the great altar. He lay in the middle of the choir, arrayed in his pontifi- cals, until the third day ; and was then buried in this attire, bearing his crosier in his hand. See Helyot Histoire des Ordres Monastiques.

(c) ABBOT, George, archbishop of Canterbury, was the son of a cloth-worker at Guildford, in Surrey, where he was born on the 29th day of October, 1562. While yet a child he displayed a quickness of appre- hension, and an extent of capacity, which seemed to mark him out for future eminence. His fatlier, ambi- tious to cultivate his genius, resolved to educate him for the church, which, to a person of his narrow for- tune, seemed to afford tiie fairest prospect of advance- ment. Accordingly, youna,' Aljbot, after receiving tlie first rudiments of literature in his native town, was, at the age of sixteen, entered a student of Baliol College in Oxford. Passing througli the rc:;ular course of gra- duation, he, in a few years after, took orders, and dis- tinguished himself as a preacher, by the energetic eloquence of his discourses. Nor did his talents and acquirements excite alone the admiration of his lite- rary associates; tiiey procured him a more important advantage, the favour of the great. Under the patron- age of the earl of Dorset, he was thrice elected vice- chancellor of the miiversity; and a])pointed first to the d^iery of Winchester, and afterwards to tliat of Glou- c^cr. Wiien the translation of the Bible \vas under- taken by the direction of king James, Dr Abljot was the second of eight learned divines in the university of Oxford, who were intrusted with the charge of trans- latuig the Gospels and the Acts of the Apostles. Ho\\ ably the task was executed, is sufficiently known by every one who has compared their jjjrersion with the original. After the death of the carl of Dorset, Abbot became chaplain to George Hume, earl of Dunbar, whom he accompanied to Scotland in 1608, to assist him in esta- blishing an union between the Scottish and English churches. The prudence and moderation which he displayed in conducting this delicate business, raised him very high in the estimation of the king, who seem- ed to tiiink no preferment too great for his services. On his return to England, he was appointed bisliop of Litchfield and Coventry ; in this situation he had re- mained only two months when he was preferred to the see of London ; and next year he was consecrated arch- bishop of Canterbury. Abbot had the singular felicity of reflecting, that these high rewards were a just and spontaneous tribute to his virtues. He had never courted patronage by any unworthy compliance with the desires of those who had preferments to bestow ; nor could even the gratitude which he would naturally feel towards his sovereign for his present high eleva- tion, betray him into one departure from that purity and rectitude which became his sacred character. When James, misled by his partiality to the unprincipled Ro- chester, was solicitous to procure a divorce between lady Frances Howard and the earl of Essex, the arch- bishop resisted it with intrepid firmness. On a subse- quent occasion, when the royal decree for the permis- sion of sports and pastimes on Sunday, was to be pro- claimed at Croydon, he ventured to prohibit it from being read. In short, he maintained in all his conduct an inviolable regard for religion, which, combined with his exalted talents, gained him the esteem and confi- dence even of those whom he found it his dutv to op- pose ; insomuch that all the great transactions of church and state were, in a certain degree, regulated by his counsels or his influence. Zeal for the Protestant re- ligion induced him eagerly to promote the union be- tween the Elector Palatine and the princess Elizabeth; and the same motive prevented him from agreeing to the resolution which the king had formed of marrying the prince of Wales to the infanta of Spain. Amidst these public avocations, the duties of private beneficence were by no means forgotten. He had long meditated the erection of an hospital in bis native town ; and as he now began to feel his ln^alth decline, he has- tened the execution of his project, saw sir Nicholas Kcmpe lay the first stone, and afterwards endowed the hospital in a very munificent manner. The satisfaction imparted by these deeds of charity, was interrupted bv an unfortunate accident. While he was one dav en- gaged inhuming in the park of lord Zouch at Bramzih an arrow which he shot from a cross-bow at one of the ABB ABD deer, struck his lordship's keeper, and killed him on the spot. This involuntary homicide pierced with keen anguish the heart of the amiable prelate. He sunk into a deep and settled melancholy ; observed the fatal day as a monthly fast ; and, to make some compensation to the widow, settled on her an annuity of twenty pounds sterling. Yet there were not wanting persons mali- cious enough to endeavour to turn this accident toAis ruin ; and though his majesty wrote him with his own hand a consolatory letter, and declared that "an angel might have miscarried in this sort," it was thought necessary to appoint a commission to investigate the affair. Tlie result of their inquiry was, that he received a complete dispensation under the great seal, and was declared fully irAltled to the exercise of archicpiscopal authority. During the whole reign of James, he was treated with that kindness and respect to which his vir- tues intitled him. Nor was the primate, on his part, deficient in gratitude. Though worn out with infirmi- ties, he attended his sovereign during his last illness with affectionate and urn-emitting solicitude, and saw hun expire on the 27th of March, 1625. From that moment his influence began visilily to de- cline. His inflexible virtue, which was a perpetual censure on the manners of Charles and his profligate minister induced him frequently to oppose their mea- sures. His principles of liberty were alarmed by the unconstitutional demand of a general loan ; and his in- dignation was strongly excited against those mercenary ecclesiastics who prostituted religion to the support of such a flagrant infringement on the subject's rights. He refused, therefore, to license a sermon which Dr Sibthorpe had written lor this disgraceful purpose ; and Buckingham eagerly seized the opportunity of gra- tifying his hatred against the worthy primate. At his instigation. Abbot was suspended from the archiepis- I'opal office, l)anished from London, and ordered to con- fine himself at one of his country seats. On the con- vocation of parliament, however, it was found necessary to restore him; and such was his popularity, that he was employed by the lords as the only person who could moderate the pretensions of the commons, in the petition of right. At court his presence was extremely unwelcome ; his authority was entirely superseded by the intrigues of Laud; and the indignities which he sufiered induced him to withdraw to Croydon, where he died on the 4th of August, 1633, at the age of seven- ty-one. He w'as buried in the church of Guildford, where a magnificent monument was erected to his memory. The cluuxh of England cannot boast of a prelate more truly respectable than Abbot, archbishop of Can- terbury. Offices which are open to merit, independent of rank or fortune, w ill often be filled by men conspi- cuous for talents and virtue; yet it not unfrequently happens, that high elevation destroys, or at least im- ])airs the excellence which led to its attainment. But Abbot was not less remarkable for his moderation, his integrity, and his firmness in the exercise of his exalt- ed office as primate, than for his modesty, his unaspir- ing temper, and his uncorruptible virtue in more ob- scure and hunible siuuitions. He seems to have been influenced in all his conduct by the spirit of the religion which he jjrofessed. Though naturally mild and un- offending, he was resolute in opposing whatever his conscience disapproved; dutiful to his sovereign, he was, at the same time, solicitously attentive to the rights of the subject: zealous for tiie respectability of his order, he wished to promote it, not by constrained reverence for the clerical dignity, but by the exemplary purity of the clerical life. His enemies branded him as a puritan, but that was a term of reproach bestowed, without discrimination, by the licentious and unprin- cipled courtiers of Charles, on all who refused to admit the unlimited prerogative of the crown; and it is, per- haps, the most striking proof of his excellence, that malignity could never throw any fouler imputation on his character.

While regius professor of divinity at Oxford, the king was so much gratified by his lectures on the supreme power of kings, that he pro- moted him to the see of Salisbury, to which he was con- secrated by his brother the archbishop in 1515. Having filled it little more than two years, he died in 1617. (c) ABBREVL\TION, is the shortening of a word by omitting some of the letters. Those languages which consist chiefly of consonants, such as the Hebrew, may be said to be written altogether in abbreviations, be- cause a number of subsequent consonants would be mute, without the substitution-of vowels: In such lan- guages, tlierefore, it is in the omission of these vowels that the abbreviation consists. Abbreviations have been particularly used by ancient lawyers and physicians. Many of them remain to this day, and books in explanation of them have been pub- lished, as if they had been in a foreign language. An- cient manuscripts, particularly those of the 12th, 13th, or 14th century, abound with contractions to such a de- gree, that a whole word is sometimes expressed by a single letter, which greatly increases the difliculty of reading them. See Contractions. The numerous abbreviations found in the relics of Roman history, and others which are still in use, will be found under the article Character. See Dix'ersions of Purtrtf, chap. i.

During the reign of Lysimachus, the in- habitants of Abderavvere said to be afflicted with a burn- ing fever, which reached its maximum on the seventh day, and which affected their imaginations in such a man- ner, that every one fancied himself a player. The fa- vourite drama of this theatrical city, was the Androme- da of Euripides ; and it was not uncommon to see groups of these tragedians spouting in the streets with all the fervour and sincerity of real actors. Lucian, who re- lates this incredible story, accounts for it from the fol- lowing circumstance. During a very sultry summer, the Andromeda of Euripides was performed in Abdera by the celebrated actor Archelaus. When the audience was dismissed, several of them were seized with a delirious fever; and as the various incidents of the play had made a deep impression upon theirminds, they began, during the paroxysms of the disease, to imitate the gestures and looks of the leading characters ; and pronounce the bro- ken sentences which their memory had preserved. The disease was said to have been epidemical, and therefore the whole inhabitants were seized with this dramatic mania. Among other wonders, the grass of the surrounding country is said to have been of such a noxious quality, that the horses which fed upoiiitwere seized with mad- ness; and during the reign of Cassander, king of Mace- don, the houses were so inundated with tribes of rats and frogs, that the inhabitants were obliged to surrender them for a while to the devastation af these invaders. Though the stupidity of the Abderites is proverbial among ancient authors, yet Abdera had the honour of giving birth to many illustrious men ; among whom were Democritus, Anaxai-chus,Protagorus,Hecateusthe his- torian, and Nicaenetus the poet. Abdera was formerly celebrated for its gold and silver mines ; but is now re- duced to an insignificant village. See Plin. JVat. Hist. lib. XXV. cap. 8. Justin, lib. xxv. cap. 2. Lucian.

(to) ABDOLLATiPH,aii Arabian physician, born at Bag- dad in 1 161, to whom posterity is indebted for a minutr and interesting account oi Egypt. After having studied grammar, rhtloric, history, poetry, and the dogmas of the Mahommcdan law, h'. began to travel at the age ol 28. He reached Mosul, where he remained a year, giv- ing lectures iti someof tliv colleges. He next proceeded to Damascus, where he ].>revailed in a controversy ovei' Al-Kendi, a famous grammarian ; and then advanced towards Jerusalem. Having learned that Saladin, king of the Saracens, who h;,d seized on the sovereignty of Egypt, and endeavoured to expel the Christians from the Holy Land, was encamped near Acre, he repaired thi- ther, probably to obtain a protection during his travels; but he found the king overwhelmed with mortification, at a signal defeat which he had received from the Chris- tians, and incapable of admitting him to his presence. One of his principal officers, however, Bohaddin Ebn Shaddad, to whom Abdollatiph was known, offered him his patronage, and recommended him to one of the chief men of the court, Ali-Kadi Al-Fadelo, who promised him a pension if he would return to Damascus. But Abdol- latiph chose rather to travel in Egypt ; and with this view went to Cairo with the recommendations of Al- Fadelo. Having understood, that Saladin had conclud- ed a peace with the Christians, and was then at Jerusa- lem, he went thither, and experienced the most gratify- ing reception. He afterwards delivered lectures in the great church or temple, called Al-Aksa. Thence he re- turned to Damascus for the third time ; and in the col- lege founded by Al-Aziz, imparted instruction on vari- ous subjects to a numerous audience. Subsequent to this period, Abdollatiph travelled into Greece, where he resided several years, and afterwards visited Syria, Asia Minor, and Armenia, practising his art in various courts. At length he wished to return to Damascus, as the place of his future residence ; but he was desirous previously to make a pilgrimage to Mec- ca, on his road to Bagdad, for the purpose of presenting some of his works to the caliph Al-Mostansor Billali. He died at Bagdad in 1223. Osaiba, -an eminent Ara- bian biographer, ascribes 150 works to Abdollatiph. The only one extant is his account of Egypt, which was brought to Europe in manuscript by Dr. Pococke, and deposited in the Bodleian library at Oxford. This work has been lately published by Dr. White, accompanied with an elegant Latin Version, (c) ABDUCTION, in Law, is the act of carrying off a woman,and marryinghcr against her will.

Though we are uncer- tain what were the precise reasons of this preference, or in what manner it was testified, we know that Cain, in consequence of it, conceived the most diabolical en\y and hatred at his brother, and, having invited him into the field, cruelly murdered him. Abel is frequently mentioned in the New Testament, and is placed by our Saviour, at the head of the list of saints, who had been persecuted for righteousness' sake. His martyrdom is not celebrated by the Greek churches, though they have feasts in honour of every other patriarch : and even among the Roman Catholics, his name does not appear in any catalogue of the saints or martyrs, till the 10th century. He is invoked, however, in several of the lita- nies, for persons at the point of death, and is said to be honoured by the Ethiopians annually on the 28th of De- cember. See Univ. Hist. vol. i. p. 150 — 154. (rf) ABEL, Charles Fkedekic, a celebrated composer and performer of music. He left Germany, his native country, in 1759, and, coming over to England, he was soon noticed as a musical performer, and obtained the office of chamber-musician to the queen, with a salary of 2001. a year. He was irascible and overbearing in his temper, and was so fond of ardent spirits, that he died at London of excessive drinking, in 1787. According to the celebrated Dr Burney, the compositions of Abel ■were easy, and elegantly simple ; and his superiority in writing and playing an adagio was so great, and he ex- pressed the most pleasing, yet learned modulation, the richest harmony, and the most polished and elegant melody, with such feeling, taste, and science, that no other musical composition or performance could be compared with it. "The knowledge Abel had acqui- red in Germany," says Dr Burney, "in every part of musical science, rendered him the umpire in all musical controversies, and caused him to be consulted in all dif- ficult points. His concertos, and other pieces, were very popular, and frequently played on public occasions. Tb.e taste and science of Abel were rather greater than his invention ; so that some of his later productions, com- pared with those of younger coniposers, appeared some- what languid and monotonous." See Burney's Hist, of Music, vol. iv. (w) ABELARD, (or Abailard) Peter, celebrated for his learning and misfortunes, flourished in the twelfth century, under the reigns of Louis le Gros, and Louis le Jeune. He was born in the village of Palais, in Brit- tany. He gave early indications of an acute and lively genius, which his father, a man of rank and opulence, resolved to cultivate by the most liberal education. Young Abelard amply repaid his father's care, by his rapid progress in science, and the ardour with which he prosecuted his studies. In the height of literary enthusiasm, he renounced the rights of primogeniture in favour of his brothers, that, relieved from all lower concerns, '.le might give his undivided attention to phi- losophy. It is to be regretted, that the science of that barbar- ous age presented no objects more worthy of such ge- nius and application. Logic became his favourite study ; and so fond was he of wielding the weapons of argu- mentation, that he travelled into dilVerent provinces in quest of disputes, like a knight-errant in search of ad- ventures. Tiiis romantic expedition terminated at Paris, where he met with William do Chan'pcaux, a celebrated professor of philosophy, and soon became his favourite disciple. Their friendship, however, was of short continuance. The penetrating Abelard easily detected the fallacies of the professor's reasoning ; and Champeaux, perplexed and foiled by the ([uestions and arguments of his presumptuous scholar, conceived against him the most rancorous hatred. The senior students, envious of Abelard's growing reputation, took part in their master's resentment. But this opposition served only to increase the young logician's presump- tion. Thinking himself qualified, by his attainments, to impart instruction instead of receiving it, he resolved to establish a school of his own. Melun, where the French court then resided, was the theatre which he chose for the display of his talents. Champeaux made every exertion to prevent the erection of this rival school; but through the influence of some powerful courtiers, who were the professor's enemies, Abelard prevailed. He soon eclipsed his antagonist's reputa- tion, and, elated by his success, removed his school to Corbeil, that he might engage him in closer and more frequent encounters. Here his excessive application threw him into a dangerous illness; and his physicians, whom he afterwards suspected of being in league with his adversary, advised him to retire to Brittany for the benefit of his native air. On returnuig to Paris about two years after, he found that Champeaux had resigned his chair, and entered into a convent of canons regular. In this new situa- tion, however, he continued his lectures. He had broached an opinion soniewhat similar to the doctrine of universals, afterwards adopted by Spinoza. Abelard again entered the lists with him, and pressed him so vigorously, that he was forced to renounce his favourite tenets. The monk incurred general contempt; his an- tagonist was hailed with universal applause ; and, to complete his triumph, the professor m whose favour Champeaux had resigned, inlisted under the banners of Abelard, and became his disciple. Such success naturally inflamed the animosity of his opponents, and stimulated their activity. Through Champeaux's in- fluence, the converted professor was discarded ; and Abelard himself was assailed by such a furious storm of persecution, that he was forced to quit Paris, and take refuge in Melun. Hearing, soon after, that Champeaux, with his whole train of monks, had retired to a country village, he w em and posted himself on mount St Genevieve, and thence, as from a battery, levelled his logical artillery against the professor, who had been appointed at Paris after the dismissal of his own convert. Champeaux hastened with the host of his convent to the relief of his besieged friend. But his assistance was unavailing ; the philo- sopher was deserted by his pupils, and retired to a mo- nastery to conceal the shame of his defeat. Abelard and Champeaux still continued the contest, in which the former was uniformly victorious. Meanwhile he ABELARD. 11 was allied from the conllict to visit his parents, who had resolvetl to spend the remainder oi' lilb in a con- vent. During his absence, his rival was made bishop of Chalons. Abelard, on his return, finding that he might quit his school, without the suspicion of being forced irom the field, resolved henceforth to devote himself to the study of divinity. With this view he re- moved to Laon, where Anselm then lectured with great reputation. Abelard, however, was so little satisfied with his abilities, that he soon forsook his lectures, and gave his days and nights to the study of the Scriptures, and the ancient fathers. In a short time he found him- self qualified for lecturing on theology, and commenced an exposition of Ezekiel, in a manner so plain and en- gaging, as to attract an incredible number of admirers. The jealousy of Anselm was roused, and Abelard was again compelled to return to Paris. Here he contiiuied his lectures on Ezekiel; and his reputation as a divine was no less flattering than that which he had formerly enjoyed as a philosopher. But, in the midst of this success, his happiness was still incomplete : a passion, stronger than literary am- bition, now occupied his breast; and he began to sigh for pleasures, which neither learning nor fame could impart. Yet his ambition attended him even in love. In the bloom of life, elegant in his manners, and grace- ful in his appearance, he was confident of success to his addresses wherever he should condescend to pay them, and resolved to be satisfied with no ordinary conquest. His choice did not long remain undecided. A young lady, named Heloise, reputed niece of Fulbert, a canon of the church of Notredamc, happened to re- side near the place where Abelard lectured. She was in her eighteenth year, when the heart is most tender and susceptible. To the most exquisite beauty, she united mental accoiTiplishments equally admirable : and her charms were heightened by such a graceful and modest air, as rendered their influence irresistible. Abelard could not aspire to a lovelier object. He saw her, conversed with her, and was captivated. Philoso- phy and divinity were forgotten, and his whole mind was bent on the completion of those desires which Heloise had inspired. A most favourable opportunity soon occurred. Ful- bert, who loved his niece, was desirous to cultivate her genius and propensity for learning. He had already hired masters to instruct her in several languages ; and would gladly have indulged her desire of attaining a knowledge of the higher branches of literature: but he was fond of money; and though anxious for his niece's improvement, he wished to eff'ect it with little expense. He was, therefore, highly pleased, when Abelard proposed to board in his house. He requested him to devote some of his leisure hours to the instruc- tion of Heloise in philosophy ; resigned her entirely to his authority ; and even enjoined him, if he should find it necessary, to inforce his precepts by compulsion. Abelard undertook the charge with transport; though, by a refined dissimulation, he seemed at first unwilling to agree to the canon's proposal ; alleging, that the sciences in which he wished his niece to be instructed, wer-.- beyond the reach of female intellect. He con- trived to render his instructions extremely pleasing to his fair pupil : Instead of the dull precepts of philoso- phy, he taught her the delightful lessons of love; and insinuated himself so completely into her affections, that she was willing to comply with his fondest wishes. Fulbert had a country house at Corbcil,to vihich, as a place of retirement favourable to study, the lover.s used frequently to repair. They spent ^^llole monllis in this retreat, abandoning themselves, withoiit fear of observation or of censure, to the transports of a mutual passion. The vigour of Abelai'd's mind was percepti- bly impaired by this criminal indidgt;nce. His public performances were disgracefully mean. He became averse to study ; and the hours which he could steal from the soft endearments of love, were employed in the composition of amorous lays. So striking a change naturally occasioned surmises; and the unguarded be- haviour of the lovers soon convinced the world, that their secret hours were not always spent in the study of the sciences. Fulbert alone had no suspicion of their intimacy. His partiality to Heloise, and his confidence m her preceptor, prevented him from giving credit to the rumours which prevailed against them, till, awa- kened by the numerous hints and discoveries, which were daily communicated to him, he watched their conduct with the closest vigilance, and surprised them in a moment of criminal enjoyment. An inmiediate separation was the first consequence of this discovery. With the ingenuity natural to lovers, they still found means to continue their interviews ; and one evening, after the transport of meeting, Heloise acquainted Abelard, that she began to feel the effects of their fa- miliarity. Abelard proposed, that she should remove to the house of his sister in Brittany ; and Heloise, dis- guised in the habit of a nun, set oft' without delay. After her departure, Abelard waited on the canon, explained to him the reason of his niece's withdrawing, and endeavoured to appease his rising fury, by offering to make any reparation for his offence. Fulbert insisted on their immediate marriage, to which Abelard con- sented. But Heloise, with the most romantic and un- paralleled excess of love, remonstrated against an union, which might perhaps diminish their mutual at- tachment, and would certainly prevent the advance- ment of her beloved Abelard. Her objections were with difficulty overcome ; and, on her return from Brit- tany, they were married in the most private manner. As it was the interest and the wish of Abelard that their marriage should be kept secret, Heloise, regard- less of her own reputation, denied it so solemnly and obstinately, as to obtain general credit. Her uncle, on the other hand, anxious only to conceal her reproach, was highly incensed by her false and shameless beha- viour. To screen her from tlie effects of his resent- ment, Abelard sent her to the convent of Argenteuil, where she assumed the habit of a nun. She did not, however, take the veil, that it might still be in her power, in more favourable circumstances, to return to the world. Fulbert, regarding this as a fresh instance of her seducer's perfidy, meditated schemes of deep revenge. By means of a treacherous domestic, assas- sins were admitted into the chamber of Abelard, while asleep ; and, by the canon's direction, inflicted upon him the most cruel and degrading mutilation. Shame and despair drove him into the darkness of a monas- tery, where his only consolation was the conversation and condolence of Heloise, whose affection did not seem diminished by his misfortime. At the age of twenty- two, while yet warm in youth, and glowing in beauty, she assumed the veil, in compliance with his request, and renounced for ever the pleasures of society. In a few years, Abelard was reconciled to his unhap- B 2 ■'12 ABELABD. py fate, and his literary ambition revived. In the mo- iiastery of St Dcnys, to which he had retired, he began to comment on the Acts of the Apostles ; but the dis- orderly monks, ofl'cnded by the freedom with which he censured their irregularities, refused to listen to his lectures. With the consent of the abbot, he withdrew from this licentious fraternity, and established a school at Thibaud, in Champagne. His fame attracted such numbers of scholars, not only from the remotest pro- vinces of France, but likewise fiom Rome, Spain, Eng- land, and Germany, that they could neither be supplied vvith lodgings, nor with food. His fortune would soon have equalled his celebrity, but the active persecution of his enemies again involved him in calamity and dis- grace. Alberic of Rheims, and Lotulf of Lombardy, whom he had offended while at Laon, and who were mortified to see their schools deserted for Abelard's, pretended to discover heresy in a work of his, intitled. The Mystery of the Trinity. They prevailed with the archbishop to assemble a council at Soissons, and Abe- Jard, without being heard in his defence, was condemn- ed to burn his book with his own hands, anu~to confine himself within the convent of St Medard. So keenly did he feel the severity of this sentence, that he himself declares, the unhappy fate of his writings affected him more deeply than the crudest of his sufierings. After a short confinement in St Medard, he was or- dered to return to St Denys. Here his restless fondness for disputation furnished the malice of his enemies with an additional accusation against him. He had hinted, that Dionysius, the Areopagite, could not be the patron of their monastery ; as it was not probable he had ever been in France. This blasphemous opinion was speedi- ly reported to the archbishop, who threatened to de- liver up to the secular power the audacious and impious offender, who liad thus dared to reflect on the honour of his convent, and of the kingdom at large. Abelard, alarmed by his n^enaces, fled to the cloister of Troies, in Champagne, where he remained till the storm had blown over. On the death of the abbot, which happened soon after, he obtained permission to live where he pleased. Tired, at last, of this perpetual conflict v/ith prejudice and malignity, he wished to spend the remainder of his days in some peaceful retirement, where, with the so- ciety of a few chosen friends, he might solace himself for the many injuries which he had sustained. With this view, he chose a solitude m the diocese of Troies ; and havmg there obtained a portion of ground, by per- mission of the bishop, he built a small house and a chap- el, which he dedicated to the Most Holy Trinity. His reputation followed him even into this sequestered re- treat. Scholars flocked to him fi'om all quarters ; and, building little huts for themselves in the desert, were content to live on herbs and roots, that they might enjoy the instructions of this extraordinary man. As a inemo- rial of the happiness which he enjoyed in this solitude, he dedicated his chapel, which had been enlarged by the liberal contributions of his scholars, to the Holy Chost, by the name of the Paraclete, or Comforter. But his tranquillity w?s soon disturbed by the envy of his former persecutors, Alberic and Lotulf, who pretended to discover heresy in the name which he had given to his chapel ; and alleged, that he thus artfully designed to insinuate the doctrines which he durst not openly avow. Their persecution was tlie more formidable, as they were joined by St Bernard and St Norbet, two popular zealots, who raised such a clamour against him, that even his best friends were either carried away by the general prejudice, or were afraid to show any dis- position to favour him. So complete was his misery, that he often formed the resolution of forsaking Christendom, and seeking among heathens the security and peace which was denied him among Christians and monks.* The duke of Brittany, compassionating his misfor- tunes, appointed him to the abbey of St Guildas, in the diocese of St Vannes. The monks had already chosen him as their superior, and he naturally hoped, that his new situation would prove a safe asylum from the rage of his enemies. But he had only exchanged one source of misery for another. The profligacy of the monks, and the tyranny of the nobleman, who was the superior of the abbey, and who had deprived it of the greater part of its revenues, gave him much vexation, and exposed him to many dangers. Poison was fre- quently mingled in his food, and, when that failed, in the holy eucharist itself. In vain did he suspend over the mutinous the terrors of excommunication; he lived in perpetual fear of assassination, and compared his situation to that of Damocles, while, seated at the table of the Sicilian tyrant, v/ith a naked sword suspended by a single hair over his head. Whilst Abelard thus sufl'ered in St Guildas, Heloisc was equally unhappy at Argenteuil. The nuns, of whom she was prioress, had become so licentious, that Lugger, abbot of St Denys, taking advantage of their irregularities, deprived them of their monastery, and established monks of his own in their room. On leav- ing Argenteuil, she applied to Abelard, who, by permis- sion of the bishop of Troies, gave her the house and chapel of the Paraclete, and there founded a nunnery. Here she conducted herself witli the greatest prudence, piety, and zeal. " The bishops loved her as their child, the abbesses as their sister, and the other religious as their mother." Abelard made frequent journeys from Brittany, to promote the interests of this rising house, and to escape from the vexations which he experienced in his own abbey. But finding, that, notwithstanding their misfortunes, the passion of Heloise was reviving in all its former ardour, he resolved to separate himself from her for ever. He reminded her, that, to make their retirement useful, and their penitence sincere, it was neccssaiT that they should forget each other, and think foi' the future of God alone ; and, having given her directions for her own conduct, and the manage- ment of the nuns, he bade her a last adieu, and returii- ed to his abbey. A long interval had elapsed since their separation, when a letter of Abelard to his friend Philintus fell by chance into the hands of Heloise. It contained a long account of all his persecutions and mis- fortunes ; and Heloise was so deeply affected by the perusal, that she could not avoid writing him in all the tenderness of passion, and reproaching him for his long silence. This was the origin of that celebrated cor- respondence, which has been preserved in Abelard's works, and which Pope has immortalized by tlie har- mony of his numbers. • His words are rcm:,rkalile : — " Sspe autem (Dens scit) in tantam lai)sus sum desperationem, ut Christianorum finlbus nd fjenles transire disponercm, atque ibi qiiiete sub qiiacunque tributi pactione inter iiiiinicos Christi, Christiane vivere." Opera, p . 32. excessis Melariii ABE ABE IS About ten years after his return to St Guiklas, liIs enemies broui^ht a new charge of heresy against liim, before the arclibishop of Sens. At his own desire, permission was granted him to defend his doctrine be- fore a public assembly. For this purpose, the council of Sens was convened in 1140, in which Louis the Se- ventli :is3isted in person. St Bernard was his accuser, and delivered to the assembly some propositions, drawn from Abelard's book, which were publicly read. Abe- lard, dreading the malice and unfairness of his enemies, appealed to the pope. But he had been anticipated by St Bernard, who prevailed with the pontiff to con- firm the sentence, which, notwithstanding his appeal, the council had pronounced against him before he had time to present himself before his Holiness's tribunal. The pope, likewise, ordered his books to be burnt, himself to be confined, and to be for ever prevented from teaching. Soon after, his Holiness was appeased by the intercession of the abbot of Clugni, who, with great humanity, received Abelard into his monastery, reconciled him with St Bernard, and admitted him as a religious of his society. In this last retirement, Abelard experienced every kindness, till, weakened by age, and afflicted with complicated disease, he was sent to the priory of St Marcel, near Chalons, where he died on the 21st of April, 1 142, in the sixty-third year of his age. His body was sent to the chapel of the Paraclete, according to a former request of Heloise, and his own desire. She survived him for 20 years, distinguished for her learning, her piety, resignation, and exemplary conduct. She died on the 17th of May, 1 163, and desired to be buried in the same tomb with Abelard, whose memory she had cherished with un- diminished affection till the last moment of her life. The following epitaph was inscribed on her tomb :* Hie, Sub eodem marmore, JacenC Hujus monasterii Conditor, Petrus Abelardus, £t Abbatissima /i7i>na, Heloisa, Olim studiis, ingciiio, infaustis riufitiis, Et fjanitentia, JVunc, teterna, ut sfieramus,J'flicitate conjuncti.

Here, imder the same marble, lie Peter Abelard, Founder, and Heloise, First Abbess of this Monastery ; Once united in studies, in genius, in unhappy nuptials, and Penitence, Now, as we hope, in Eternal Felicity. Abelard died on the 21st of April, 1 142 ; Heloise, on the 17th of May, 1163. On reviewing the life of Abelard, wc find much to admire, but more to condcnm. Singular, indeed, must have been the talents of thai man, who, in an aji^t when logic was almost the only science, could foil the first champions in the field (jf disputation ; and who, under every circumstance of discouragement, could draw, even to a solitai-y desert, admiring and crowded audi- tories from the most distant countries of civilized Europe. But vanity and selfishness were the pre- dominant features in his character. Even modesty, it is trvie, will not always shield superior genius from envy and persecution; but he may fairly be suspected of unusual petulance and presumption, who never chang- ed his situation witiiout exciting new enemies, and who was driven from every society with which he was con- nected, by the dissensions and animosities which he himself had occasioned. His conduct to Heloise will stamp his memory with perpetual infamy. Had he merely been impelled by the ardour of resistless pas- sion, his crime, though still unjustifiable, might have found some apology in human frailty. But black must have been the heart, which could form against such lovely excellence a deliberate plan of seduction, and could requite with selfish jealousy, and cold indif- ference, the most disinterested and faithful affection. Youth and inexperience plead the excuse of Heloise ; and if we must still condemn her crime, her amiable sensibility, and romantic generosity, soften at least the severity of our censure. The works of Abelard, written in Latin, are, " An address to the Paraclete on the study of the Scriptures; Problems and Solutions ; Sermons on the Festivals ; a Treatise against Heresies ; an Exposition of the Lord's Prayer ; a Commentary on the Romans ; a System of Theology ; and his Letters to Heloise, and others." The best edition of the works of Abelard, is that which was published at Paris, from the MSS. of Francis D'Amboise, intitled Abxlardi et Hcloiste, conjugis ejus, o/!cra, ex editione Andreae Quercetani, quarto, 1616, sometimes dated 1606, and 1626. (/t) ABELIANS, a sect of heretics in Africa, who ap- peared in the reign of Arcadius. According to St Augustin, they enjoined marriage, but did not permit any sexual intercourse. In order to preserve the sect, they were therefore obliged to adopt a boy and a girl, who were to inherit their effects, and marry upon the same hard terms. This unnatural association, how- ever, did not flourish long. As soon as its novelty was gone, the number of its members diminished; and it was extinct in the reign of Thcodosius. The tenets of these heretics seem to have been founded on the sup- position that Abel was married, and died without issue.

(to) ABERBROTHOCK,or Arbroath, a sea-port town, and one oi the royal boroughs of Scotland, situated on the mouth of the small river Brothock, in the county of Angus, about 56 miles N. N. E. of Edinburgh. This town was erected into a royal borough aliout tlie middle of the 12th century, by king William the Lyon, who, in 1 178, founded its abbey, dedicated to St Thomas a Becket ; but it was not consecrated till the year 1233. The remains of its royal founder are in- terred there, now undistinguished amidst plebeian dust. This monastery was one of the richest in Scotland ; the monks were of the Tyroncnsian order from the abbey of Kelso, but were declared independent of its jurisdic- tion. It enjoyed many other uncommon privileges : a charter from king John of England is still preserved, wherein the monastery and citizens of Aberbrothock are exempted a teloniin et coyi.inetudinc in every part of England, except London and Oxford. A parliament was held at Arbroath in 1 320, when the barons of Scotland under king Robert Bruce, in a cele- brated and energetic manifesto, addressed to the pope, asserted the independence of their kingdom. In 1525, the famous cardinal Beaton, the Wolsey of Scotland, was the last abbot of Arbroath. After the destruction of the abbey, by the ungovernable fanaticism of the re- formers, its revenues were erected into a temporal lord- ship, in favour of lord John Hamilton, of the family of Chatelherault ; and lord Aberbrothock is still one of the titles of the duke of Hamilton. There is a dignity and venerable grandeur in the ruins of the abbey, which still command respect from strangers as they approach the town ; and when more closely inspected, its mould- ering Gothic aixhes, and dilapidated columns, impress the mind with high ideas of its former magnificence. With the abbey the town appears to have fallen into decay for a considerable period. But eai'ly in the last century, when the Union had diffused a spirit of com- merce into Scotland, a few individuals of property be- gan the manufacture of brown linen, which succeeded beyond expectation : it is still the principal trade of the place ; and from its quality, has acquired a celebri- ty hitherto unrivalled. The following abstract from the books of the Bro^^^l Linen Stamp-Office, Arbroath, and confirmed to the honourable the Board of Trustees, by the affidavit of the stamp-master, will show the progressive increase of the linen-manufacture for the last four years.

Besides the above, the manufacture of sail-cloth is extensive, and may be fairly calculated for some years past at not less than 100,0001. annual value. Ten sail- cloth manufacturers are contractors for supplying his majesty's navy with canvas ; the rest of the canvas manufactured goes for exportation and home consump- tion. From 1500 to 2000 tons of flax and hemp, exclu- sive of lintseed, tallow, and ashes, are animally import- ed from the Baltic : Tiie above, including a tan-work, conducted with spirit and activity, are the principal branches of trade in Arbroath. It enjoys a sale har- bour, entirely artificial, which has been twice extended within these last four years, owing to its increase of shipping, which at present consists of upwards of 50 vessels, comprehending about 4000 tons register ; their general size being from 60 to 150 tons : Of these, three vessels belong to a company of the merchants, and are constantly employed in the London trade, the greater part of the linen and sail-cloth manufactured being shipped direct for that port : The rest are chiefly em- ployed in the Baltic and coasting trade. In the year 1781, an attack was made upon the town by a French privateer, after which a fort was built by subscription. It is constructed in the form of a cres- cent, on a small hill adjoining to the harbour, mounted with six l2-pounders, and commands the coast to a considerable distance. The increase of population, and prosperous state of commerce in Arbroath, will most forcibly appear from the following facts. There is a respectable gentleman still alive there, who recollects the time when he could have sat down and told the name of every householder in the town and suburbs. And the writer of this article has just now befoie him, a receipt from the town-trea- surer of Arbroath, granted to the tacksman of the shore- dues, for the year 1717, the amount of which, rendered into sterling money, makes their annual value 29/. 6«. 4d. : And in the year 1807, the shore -dues were sold by public roup for 735/. sterling. To these may be added the income arising from other duties and property. be- longing to the town ; making the present annual re- venue from 1700/. to 1800/. sterling. A new town-house, including prisons, town-hall, town-clerk's office, and register-room. Sec. is just now building, after a very elegant plan, by Mr. David Logan, architect. This building, when completed, will add considerably to the embellishment of the High Street, which, from a want of taste too prevalent in former times, is crooked and irregular. In the year 1797, a private library was established by a few of the principal inhabitants and neighbouring gentlemen, which at pre- sent consists of 1 12 members, contains about 2000 vol- umes, is rapidly increasing, and promises to promote tlie diffusion of literary and scientific knowledge. The old town-house, a large and respectable building, has been recently purchased by the guildry, and will be occupied as a guild-hall, coflee-room, library -room. Sec. Within these last twenty years, a very great addition has been made to the extent and population of the town, by building upon ground taken in perpetual feu from the adjoining proprietors, m which more attention has been paid to the regularity and uniformity of the streets. The greater part of these additions are w'thout the royalty, and in the neighbouring parish of St Vigeans. The population, including tlie suburbs, may be reckon- ed about 9000. Arbroath is healthfully situated, enjoys a free circula- tion of air ; and, although it cannot boast of many rich capitalists employed in trade, or wallowing in luxury ABERCROMBY/ 15 fi'om overgrown fortunes, yet it displays a spirit of pro- ^•rcssivc industry and improvement, wiiicli may be just- ly considered as tlie true source of national prosperity : And it lias often been remarked l)y stranii^ers, tiiat it exhibits pcj'haps fewer instances of abject poverty and extreme wretchedness, than most towns of equal popu- lation in Great Britain. Lat. N. 56° 32' 30". Long. 2° 34' 15". (a. is.) ABERCROMBY, Sir Ralph, K. B. was the son of George Abercromby of Tullibody, Esq. in the county of Clackmannan. He was born in 1738, and was one of five sons, all of whom rose to situations of eminence in diflerent departments of the service of the state. He entered into the army as cornet of the 3d Dragoon Guards, in 1756; and, ascending through the inter- mediate gradations of rank, he was appointed, in 1781, colonel of the 103d, or King's Irish infantry. This new-raised regiment was reduced at the peace in 1783, when colonel Abercromby was placed on half-pay. In 1787, he was removed to the command of the 7th regi- ment of dragoons. He acquired, during the long- period of his military service, great knowledge and ex- perience in his profession, having served in the Seven Years' War, and in the war with America and its allies. But the chief services which he rendered to his coun- try were those occasioned by the great contest into which Great Britain entered with France, soon after the French Revolution. He was promoted to the rank of major-general, and soon after to that of lieutenant- g-eneral ; and, in the two campaigns on the Continent, in which the British troops were commanded by the duke of York, he gave many proofs of his skill, vigi- lance, and intrepidity. In the action on the heights of Cateau he commanded the advanced guard, and was wounded at Nimeguen in the October following (1794.) It has been sometimes remarked, that the talents, as well as the temper, of a commander are put to as severe a test in conducting a retreat, as in achieving a victo- ry. The truth of this lieutenant-general Abercrom- by experienced, when he was called upon to perform the painful but important duty, of conducting a part of the retreating army out of Holland, in the winter of 1794-5. The guards, and all the sick, were on this occasion committed to his care ; and in the disastrous march from Devanter to Oldensal, he sustained the severest hardships, and experienced the most painful feelings, which had ever perhaps fallen to his lot. Harassed by a victorious enemy on his rear, obliged to conduct his troops with a rapidity beyond their strength, through bad roads, in the most inclement part of a winter uncommonly severe, and finding it alike difficult to procure food and shelter for his sol- diers, the anguish he felt in seeing their numbers daily diminish by cold and fatigue, admits of no adequate description. His gallant spirit was ready to sink be- neath the cares which oppressed him, before his arrival at the place of destination. He accomplished his object however, as well as himnan judgment, united with huma- nity, could accomplish it, about tVie end of January 1795. In the autumn of the same year, he was appointed to succeed sir Charles Grey as commander in chief of the British forces in the West Indies. Previous to his ar- rival, the French had made considerable exertions to recover from their losses in that quarter; and, besides recapturing several of their islands, they seized, to an immense amount, the property of the rich emigrants, who had fled thither from France. General Abcrcrom- liy repaired to Southampton, to take the conmiand <^C^^ tiie troops destined lor the West Indies. Theexpedi» ^^ tion was unfortunately prevented from sailing till after the equinox, and several transports were lost in endea- vouring to clear the Channel. Every possible exer- tion was however made, and the general, with his troops, at length arrived at the place of destination. Having arranged his plans, he waited the proper season for their execution ; and, on March 24, 1796, a detachment of his army suddenly attacked and obtain- ed possession of the island of Grenada. He soon after became master of the Dutch settlements of Demerara and Esscquibo, in South America. Towards the end of April, the admiral had the necessary ships in readi- ness for conveying the troops designed for an attack on the island of St Lucia. Here the enemy had a num- ber of well-disciplmed black and white troops, who de- fended the garrison of Morne Fortune with considera- ble gallantry. After experiencing much obstruction from the exertions of the enemy, favoured by the nature of the country, a suspension of arms took place on the 24th of May, and a capitulation was entered into on the 26th, by which the fortress was surrendered to the British, and the troops became prisoners of war. The island of St Vincent was next attacked, and yielded to the Britisliarms about the middle of June. This short and brilliant campaign was concluded by the command- er in chief in the island of Grenada, where his pre- sence became necessary to quell the insurgents who had taken arms against the British, and were headed by the fierce and enterprising Fedon. After the arrival of Abercromby, hostilities were speedily brought to a ter- mination ; and on the 19th of June, full possession was obtained of every post in the island, and the haughty chief, Fedon, with his troops, were reduced to uncondi- tional submission. Early in the following year (1797) the general sail- ed, with a considerable fleet of ships of war and trans- ports, against the Spanish island of Trinidad, and, on the 16th of February, approached the fortifications of Gasper Grande, under cover of which, a Spanish squa- dron, consisting of four sail of the line and a frigate, were found lying at anchor. On perceiving the ap- proach of the British, the Spanish fleet retired further into the bay. General Abercromby made arrange- ments for attacking the town and ships of war early in the following morning. The Spaniards, however, an- ticipated his intentions ; and, dreading the impending conflict, set fire to their own ships, and retired to a dif- ferent part of the island. On the following day, the troops landed ; and soon after, the whole colony sub- mitted to the British arms. Having performed these important services in so gallant a manner, and having failed only in his attempt on the Spanish island of Por- to Rico, the commander in chief returned soon after to England, where he was received with every mark of honour and public respect. During his absence on these enterprises, he was invested with the red rib- band, and soon after his return, he received the appoint- ments of governor of Fort George and Fort Augustus. In times of public peril, a commander so justly re- spected for his valour and humanity, could not ex- pect long to enjoy the delights of domestic retirement. Tiiese, his gentle mamiers and unambitious character rendered peculiarly dear to him. But he was reser- ved for other active duties, to ^\ hich the service of his country called him. 16 •abercuomby. c^ Ireland had been Jong a subject of solicitude to ritish statesmen. The great majority ot its inha- bitants, beijig attached to the Catholic religion, and having been accustomed to view with a jealous eye the superior privileges enjoyed by their Protestant brethren, were deemed the Ht objci-t.s of French arti- fice and intrigue. The leaders of the l-'rcnch Revo- lution employed these religious animosities, as well as the political discontents of the Irish, to irill.ime their minds against their sovereign and the hrilish con- stitution. When party disputes had arisen to such a height as to be attended by frequent outrages, and to threaten that country with open rebellion. Sir R. Aber- cromby was selected to fill the important station of commander in chief of his majesty's forces in Ireland. He arrived there in that character, about the middle of November 1797. Finding that the conduct of some of the British troops had too much tended to increase the spirit of insubordination, he issued a proclama- tion on the subject soon after his arrival. In this proclamation, which is written in a simple and impres- sive strain of indignant sensibility, he laments and re- proves the occasional excesses into which they had fallen, and which had rendered them more formidable to their friends than to their enemies ; and he declares his firm determhiation to punish, with exemplary severity, any similar outrage, of which they might be guilty in future. Though much has been insinua- ted against the policy of this proclamation at such a crisis, there can exist only one opinion, as to the mo- tives by which it was dictated. Nor can we cease to regard it as forming a most marked and decisive proof of the manly independence of his mind, and of the ge- nuine benevolence of his heart. He did not long re- tain his command in Ireland. The inconveniences, arising from the delegation of the highest civil and militai-y authority to different persons, had been felt to occasion much perplexity in the management of public affairs, at that season of agitation and alarm. Sir R. Abercromby, therefore, resigned the command, and marquis Cornwallis was appointed his successor, with the additional honour of Lord Lieutenant of Ireland. In the summer of the same year, Sir. R. Abercrom- by was appointed commander in chief of his majesty's forces in Scotland ; and, for a short time, the cares of his military duty were agreeably blended with the en- dearments of kindred, and the society of early friends. In the autunm of 1799, he was employed in the ex- pedition to Holland, as next in command to the duke of York. On this occasion he gave new and ample proofs of his skill and valour. But the lateness of the season, at which the expedition sailed, the extreme wetness of tlie weather, the advanced state of the enemy's preparations for defence, and the unexpected refusal of the Dutch people to receive the British as their deliverers from the yoke of France, all combined to render success hopeless. The military talents of the generals there- fore were chiefly employed to secure to tlie Brhish ar- my a strong and impregnable position, capable of being supplied by sea with provisions and stores. Having done this, they were enabled to conclude a convention with the enemy ; by which they were permitted to re- cmbark unmolested, and return to Britain. In the following year ( 1 800) tlie attention of tl»e pub- lic was drawn towards a great naval and military ex- pedition, which was fitted out by tlie English govern- ment al an immense expense. It sailed from England early in summer; the naval force under the command of admiral lord Keith, and the army commanded by sir R. Abercromby. Alter threatening Cadiz, and linger- ing for a consitlerable time in the Mediterranean, orUers at length arrived from F.ngland for the fleet,to proceed to Egypt, and the two divisions rendezvoused at Malta on the 14lh December. Thence they sailed on tlie 20th and 2 1st of the same month, carrying along with them 500 Maltese recruits, who were designed to act as pioneers. The fleet, in place of sailing direct for Egypt, which sound policy, we apprehend, should have dictated, again rendezvoused, on the 1st January, 1801, in Marmoriss Bay. The fleet, to the number of 175 sail, weighed anchor on the 23d February ; and on the 1st Alarch, it came in sight of the coast of Egypt, and on the following morning anchored in Aboukir Bay, in the very place where, a few years before, Nelson had added to the naval triumphs of his country. The violence of the wind, from the 1st to the 7th of March, rendered a landing impracticable ; and the re- sult of the inquiries, which were made during that in- terval, was, that there was no part of the coast so fa- voui-able for the attempt as Aboukir Bay. The weath- er becoming calmer on the 7th, that day was spent m reconnoitring the shore ; a service in which sir Sid- ney Smith displayed great skill and activity. Meanwhile the French, who, availing themselves of the delay of the British, obtained naval and military rein- forcements from Europe, and were fully aware of the at- tempt, which was soon to be made, though ignorant of the precise point of landing, used every exertion to counteract its success. Two thousand of their men were strongly intrenched on the sand-hills near the shore, and formed, in a concave figure, opposite to tlie British ships. The main body of the FVench amiy was stationed at and near Alexandria, within a few miles. At two o'clock, on the morning of the 8th, the British troops began to assemble in the boats ; at three, the signal was given for them to rendezvous near the Mondovi, anchored within gunshot of the shore ; and it was not till about nine in the morning, that the boats were assembled and arranged. At that hour, the sig- nal for landing was given. The boats rushed forward w ith one great impulse, and the work of destruction be- gan. Twelve pieces of cannon placed on the sand- hills, within gunshot of the boats, and the castle of Aboukir, opened a dreadful fire on our gallant sol- diers, who, crowded in the boats, were utterly unable to make the least resistance. As they approached the shore with a rapidity that seems in such circumstan- ces incredible, a torrent of grape and musketry as- sailed them, and even their enemies were confounded by the boldness of the attempt. Unappalled by this tempest of death, which, for a short time, made dread- ful havock among our troops, the 2od and 40th regi- ments, which first reached the shore, leaped from the boats, formed as on parade, mounted the heights, which seemed inaccessible, in the face of the enemy's fire, without returning a shot, charged with the bayonet two battalions, who were stationed on the summit, put them to flight, and took three pieces of cannon. In vain did the enemy endeavour to rally his troops ; in vain did a body of cavalry charge suddenly on the Guards, the moment of their debarkation. They gave way at all points, maintaining, as they retreated, a scattered, and inefficient fire. The boats returned for the remaining part of the army, which was landed before tlie close of ABERCROMBY. i; tlic same day. The troops were employed the next day in searching for water, in which they happily suc- ceeded ; and the castle of Aboukir rclusing to surren- der, two regiments were oidered to blockade it. On the 13th, the general, desirous ol forcing the iieights near Alexandria, on which a body of French, amount- ing to 6000, was posted, marched his army to the at- tack ; and, after a severe contlict, compelled them to retire. Wishing to follow up his first success, and to drive the enemy from his new position, the general pro- ceeded to reconnoitre, and, during his absence, the cen- tre of his army was exposed to a most destructive fire, from which they had no shelter, and to which they could oppose scarcely any resistance. At length, the attem])t to force the enemy's lines was deemed impracticable, and the army retired with great loss to that position, which was soon to be the theatre of struggle and of victory. Why sir Ralph Abercromby did not cither remain contented with gaining his first object on the loth, or keep his men out of the reach of the enemy's cannon, while he was in suspense about making a se- cond attack, it is not easy to conjecture. The loss of the English, on that unfoi-tunate day, in killed and wound- ed, was upwards of 1000; and the general himself had a horse shot under him. Alter the 13th, Aboukir cas- tle, which had hit'aerto been only blockaded, was be- sieged, and, on the fifth day of the siege, it was sur- rendered. On the 20th, a considerable body of tlie enemy was seen advancing toward Alexandria ; and an Arab chief gave information to sir Sidney Smith, that the French general, Menou, meant, next morning, to surprise and attack the British camp. Sir Sidney Smith, who, unwilling to confine his exertions for his country to one element, partook of all the dangers of the field, communicated tiiis intelligence at head quarters, to- gether with his own belief of its truth. The position of the French army, however, was so strong by nature and art, and it seemed so much their interest to remain on the defensive, that sir R. Abercromby could not give credit to the report. Every precaution, however, had already been used to secure and strengthen the posi- tion of his army. On the morning of the 21st March, the army was, as usual, in battle array at three o'clock. All remained quiet for about half an hour, and the troops were re- tiring to their tents, when the report of a musket on the left awakened attention, and recalled them to their posts. Scattered sounds of musketry and cannon suc- ceeded in the same quarter ; but, from the apparent weakncssof the attack upon the left, it was wisely judg- ed, that this was only a feint, and that the real object of attack was the right of the British army. After a short interval of suspense, rendered doubly awful by tlic gloom of the atmosphere and the darkness of the night, shouts were heard from the enemy, n\arch- ing in columns to the attack of the right wing of the British ; a roar of musketry and artillery succeeded, and a general action began. This is not the proper place for detailing the events of that memorable day, on which, after a long and severe engagement, the British gained a signal triumph over an assailing ene- my, much superior in numbers. The joy of victory, however, was shaded with sorrow from the irrepara- ble loss which the army sustained in the fall of its brave commander, sir Ralph Abercromby, who, blend- ing the coolness of age and experience with the ardour and activity of vouth, repaired on horseback to the Vol. I. Part I. right on the first alarm, and exposed himself to all the dangers of the field. Early in tlie action, he re- ceived a mortal woiuid in the thigh from a musket- ball ; yet he continued to move about, and give orders with his characteristic promptitude and pers|)ic'uity. In a formidable charge by tlie enemy's cavalry, he was thrown from his horse, and, in a scuHle with a French officer, whom he disarmed, he received a contusion on the breast. Still he remained in the field, unconsci- ous or regardless of his danger, till the retreat and discomfiture of the enemy gave him leisure to think of his situation. Exertion being no longer necessary, his spirit sunk beneath fatigue and loss of blood, and he was conveyed, feeble and faint, from the field of victory, amid the expressions of love and sympathy from the companions of his dangers, who were to be- hold his face no more ! He was put on board a boat, and carried to lord Keith's flag-ship. All the attempts which were made to extract the ball proving ineflec- tual, he lingered for a week in great pain, aggravated by mental solicitude respecting the army. A mortifi- cation at length took place, and on the evening of the 28th he expired ; and the joy which the great vic- tory of the 21st had inspired, was, for a season, turned into mourning. His remains were conveyed to Malta in the Flora frigate, attended by his aid-du-camp, and were interred in the commandcry of the grand master, with the highest military honours. The same frigate conveyed to England the standard of the celebrated brigade, which Bonaparte had presumptuously named, The In-uincible Legion. This flag, inscribed with the names of those battles in which the brigade had been chiefly distinguished, was valiantly, but in vain, de- fended. The corps was said to have perished to a man ; and the standard remains as a trophy to the victors, and a monument ol human pride. Having, by his talents and exertions, paved the way for that com- plete success, which in a few months crowned the la- bours of the British troops, and expelled the French from Egypt, sir Ralph Abercromby was succeeded in the chief command by his much esteemed friend gene- ral Hutchinson. This gentleman, who to the qualities which form an able commander, adds the accomplish- ments of a correct and elegant scliolar, in the des- patches which announced to the English government the death of Abercromby, pays the following affecting tribute to the memory of the veteran commander : — . " Were it permitted for a soldier to regret any one who has fallen in the service of his country, I might be excused for lamenting him more than any other person ; but it is some consolation to those who ten- derly loved him, that as his life was honourable, so was his death glorious ! His memory will be recorded in the annals of his country, and will be sacred to every British soldier, and embalmed in the recollection of a grateful posterity." (/) ABERCROMBY, Alexander, (lord Abercromby,) was the youngest son of George Abercromby of Tulli- body, and was born in 1745. Destined, probably on account of his promising talents, to the bar, he passed through all the various stages of education prescribed for our Scottish lawyers. Rut his mind was too much formed for the gaieties of fashionable ]if% to relinquish them for the irksome dnulgery of a laborious employ- ment. For some vears after he had been admitted into the Faculty of Advocates, his splendid talents were ahnost wholly obscured by indolence or frivolity; till C IB ABKlUiEEN. roused at length lo excrlion by the dread of penury, or the desire of fame, he engaged with ardent emulation in all the duties of his profession. His industry and ambition were amply rewarded. He soon became emi- nent for his professional skill, and was distinguished us one of the most eloquent pleaders at tlie bar. Ho- nours now began to crowd upon him. He was fust ap- pointed one of the inferior judges ; and, after passing through various gradations of preferment, was raised to the bench ol the supreme civil court in the year 1792 ; and in the same year was made one of the judges in the High Court of Justiciary. In his judicial capacity he was distinguished by a profound knowledge of law, a patient attention, a clearness of discernment, and an unbiassed impartiality, which excited general admira- tion. But his comitry was soon deprived of his valua- ble services, for he was seized with a distemper, which temiinated his existence in November 1795. ' Amidst the numerous and fatiguing duties of his profession, Abercromby found leisure to indulge his passion for elegant literature. Of the correctness and cultivation of his taste, we have some very happy speci- mens in the papers which he contributed to the Mir- ror, a periodical work published at Edinburgh in 1779, and conducted chieily by the Faculty of Advocates, a class of men whose genius and learnuig do honour to their country. The Mirror was revived, though under a different name, in the year 1785-6, by the same gentlemen who had established it at first. To this new work, which was called the Lounger, Abercromby contributed nine papers, which are remarkable for easy and elegant composition, justness of sentiment, and die extensive knowledge which they display of human life, (ft.) ABERDEEN, capital of the county to which it gives name, and the principal city in the north of Scotland, consists, in reality, of two distinct towns, called Old and New Aberdeen, situated at the distance of about a mile from each other, and having separate privileges, char- ters, and magistrates. Old Aberdeen stands upon an eminence which rises from the bank of the river Don, about a mile from the sea. The history of its origin is unknown, but it must be one of the most ancient towns in Scotland ; for at the end of the ninth centvny, it seems to have been a place of importance, and is said to have received some pecu- liar privileges from king Gregory the Great. His charter was lost, however, when the town was burnt by the English ; and the oldest authentic charter now ex- tant, is that of David I. who, in the year 1 154, trans- lated the episcopal see from Morthelach to Aberdeen, which he erected into a free borough of barony, holding directly of the crown. This charter has been repeat- edly renewed by different sovereigns, and was finally confiiTned by an act of George I. which vests in the free burgesses of the town the power of electing their own magistrates. About the beginning of the 14th century, the citizens who had adhered to Robert Bruce, driven to despair by the atrocities of the English garrison, came upon them by surprise, and having seized the castle, put them all to the sword. Some English soldiers, who happened to be in the neighbourhood, advanced imme- diately to revenge the death of their countrymen ; but they were met in the church-yard of St Nicholas by the Aberdonians, who defeated them with great slaugh- ter. These disasters were afterwards amply revenged'. In the >car 1333, a fleet having been sent by Edward IH. to ravage the eastern coasts of Scotland, a body of English troops landed by night, and falling upon Aber- deen by surprise, butchered a great immber of the in- haljitanls ; and were employed for six whole days in burning and pillaging the town, 'i'hree years after, when Edward himself in person invaded Scotland, and penetrated with an army as far north as Inverness, the citizens of Aberdeen encountered a party of English troops who had landed at Dunnotcr, and slew their leader. Enraged by this misfortune, Edward attacked Aberdeen on his return from the north, massacred the greater number of the iiUiabitants, and again reduced the town to rums. A new city was soon erected, how- ever, in a different situation, which, to distinguish it from that which had been destroyed, was called thc New Town of Aberdeen. Aberdeen was so much en- deared to David Bruce for its steady and zealous loyal- ty to his father and himself, that he honoured it for some time with his residence, and erected there a mint from which he issued various coins. During the civil commotions which agitated Scotland in the year 1644, the marquis of Montrose approached this town with about 2000 men, and summoned it to surrender. With this summons, it was not likely that a town, which had on all occasions displayed so much spirit, would readily comply, particularly as it was defended by a force un- der the command of lord Burleigh, not much inferior in number to that of the assailants. A battle accord- ingly ensued, in which Montrose prevailed, and many of the principal inhabitants were slain. Old Aberdeen, though now completely eclipsed by the splendour of the New Tov.n, could once boast of several magnificent edifices, and still contains some respectable buildings. Over the Don there is a fine bridge of Gothic architecture, built by bishop Cheyne in 1281. The span of its arch is 67 feet, and its height from the surface of the river, 34i feet. But tlie prin- cipal ornament of this town was its cathedral, dedicated to St Machar, whose former magnificence is strikingly indicated by two antique spires, and an aisle now occu- pied as the parish church, which are its only remains. It was founded in 1154, when the episcopal see was translated from Morthelach ; but having eitlier become ruinous, or being deemed not sufficiently elegant, it was taken down, and founded anew by bishop Alexan- der Kenninmouth in 1357. Nearly 80 years were oc- cupied in building it, and it was at length completed by bishop William Elphinstone, who was lord chan- cellor of Scotland, in the reign of James III. and keep- er of liie privy seal to the succeeding monarch. In the cathedral, there was a valuable library, which was de- stroyed at the Reformation, by those worse than Sara- cen barbarians, who demolished besides the venerable edifice itself. To the same munificent prelate, Aber- deen is indebted for its university. In the year 1494, he obtained from pope Alexander a bull, impowering him to institute studium gen^'rale, et iinh'er.iiiatis siudil generalis, for theology, medicine, canon and civil law, the liberal arts, and every lawful faculty, with the right of granting degrees according to the merits of the stu- dents. Twelve years elapsed after the date of this bull, before the college w-as founded. It was at first dedicated to the Virgin Mary, but, being greatly pa- tronized by the king, it was afterwards denominated King's College. It is a large and stately structure, containing- a chapel, library, mtiseiim, common hall; ABERDEEN. 19 aiKl lecture I'ooms. Coniicclccl vviili this college, there is a long row of modern houses lor the aceonwiodtition of the professors, and such of the students as choose to reside there. Behind those buildings is the garden of the college, with a house and garden, api)roi)riated to the principal. The museum is well furnished, and tlie library is valuable. A fund, amounting to about 7000/. is appropriated for bursaries to students who stand ui need of such support. Hector Uaethius, well known for his history of Scotland, was invited liom Paris to be its fust principal, and was allowed a salary of 40 nicrks Scots, equivalent to 21. 3*. 4t/. sterling. Besides nine professors, this college has a chancellor, general- ly a nobleman; a rector, intitled lord rector; a princi- pal, a sub-principal, and a procurator, who is intrust- ed with the management of the funds. There is in Old Aberdeen a neat town-house, built a few years ago at the expense of the conmiunity, a trade's hospi- tal for decayed burgesses and their widows, and an hospital for 12 poor men, founded by Gavin Dunbar, who died in 1532. The magistrates of this town are, a provost, three bailiffs, a treasurer, and council, with the deacons of six incorporated trades. New Aberdeen, situated on a rising ground near tne estuary of the Dee, is a large and elegant town. It has many fine streets, whose sides are lined with handsome houses, generally four floors in height, built of granite from the neighbouring quarries. In this town the notice of strangers is attracted by several public buildings, which do the highest honour to the taste and spirit of the inhabitants. On the north side of the market-place, a large oblong square in the cen- tre of the city, is the town-house, adorned with an ele- gant spire; and adjoining to it is the prison, a square tower 120 feet high, which is likewise surmounted by a spire, so that the whole has a very lofty appearance. An elegant mason lodge contiguous to this, and a bank- ing office of polished granite recently erected, opposite the town-house, give to this part of the town an air of peculiar splendour. The cross, which stands in the middle of Castle-street, is the most complete perhaps in the kingdom. It is an octagon stone building, orna- mented with elegant bas-relievos of the kings of Scot- land, from James I. to James VI. having in the centre a Corinthian column, on the top of which there is the figure of an unicorn. But the principal building in New Aberdeen is the Marischal college, founded by George Keith, earl Marischal, in 1593. It stands in Broad-street, and contains, besides lecture rooms, a public school for conferring degrees, a common hall, decorated with some fine paintings, chiefly by Jamie- son ; a library, a small museum of natural history and antiquities, and an observatory, well furnished with as- trononpcal apparatus. Its original establishment was a principal, and two pi'ofessors of philosophy ; but there have since been added, by the munificence of rich in- dividuals, a third professorship of philosophy, and others, of divinity, mathematics, chemistry, medicine, and oriental languages. There are likewise many bur- saries for poor students. The officers of this college are, the chancellor, tlie rector, the dean of faculties, the regent, who is also, ex officio, professor of Greek, and the principal. In the two colleges of Aberdeen, there were, in the year 1808, between 300 and 400 students. New Aberdeen has lately been much improved by the opening of two elegant streets, one forming an entrance from the north, and the other from tJic soutlr. The latter passes over a majestic arch of cut granite, the span of which is 130 feet, its height 29 feet, and its width within the parapets 40. In the Upper Kirkgatc is a church which formerly belonged to the Francis- cans, and which was founded by bishop Klphinstone, and finished by one of his successors. Over the Dec there is a fine bridge of seven arches, said to have been first projected by Elphinstone, who left a considerable legacy for the purpose of l)uilding it, and to have been completed by bishop Dunbar in the year 1530; it was repaired, or rather rebuilt, in 1724, by the magistrates of Aberdeen. While the buildings of Aberdeen thus display the taste of its inhabitants, its numerous charitable institu- tions bear a still more honourable testimony to their hu- manity. Of these, we shall only mention the poor-house, appropriated to the reception of the aged poor, and of destitute children; Lady Drum's hospital for old un- married women, founded in 1668, by the lady Mary, daughter of the earl of Buchan, ajid widow of sir Alex- ander Irvine of Drum ; Gordon's hospital, founded in 1733, in which, from 60 to 66 boys are clothed, main- tained, and educated ; the infirmary, established in 1742, in which about 900 patients are annually relieved ; the dispensaries which have annually from 200 to 300 pa- tients on the books of charity ; and the lunatic asy- lum, built by subscription, about half a mile from town, in the year 1800. Aberdeen carries on a considerable commerce, chief- ly to the Baltic ; though a few of its njerchants trade to the Levant, and West Indies. Its exports are knit stockings, for the manufacture of which it was long unrivalled, thread, salmon, grain and incal. The manu- facture of fine thread is carried on to a considerable extent, and the manufacture of brown linen, osnaburgs, and canvas, has lately been introduced. It seems ra- ther a reflection on the enterprising spirit of the in- habitants, that not a single decked vessel has been fit- ted out from their port for the prosecution of the her- ring or w'hite fisheries, for which their situation is so peculiarly favourable. Till lately, the trade of Aber- deen was much obstructed by the difficulty and dan- ger of approaching its harbour, occasioned by a bar of sand which was perpetually shiftirig its situation. A new pier, erected on the north side of the river, ac- cording to a plan designed by Mr Smcaton, has ef- fectually remedied that inconvenience. The pier is 1200 feet long, increasing in height and thickness as it approaches the sea, where the rounding is 60 feet diameter at the base, and the perpendicular elevation 28 feet. Near it are two batteries, mounting ten twelve- pounders. The number of British ships entered at Aberdeen in 1795, amounted to 61; of foreign vessels 5 ; and of British ships cleared out, 28. Aberdeen, united with the Ijoroughs of Aljerbrothock, Brechin, Inverbervie, and Montrose, sends one member to par- liament. Its civil government is vested in a provost, styled lord provost, four bailies, a dean of guild, trea- surer, and town-clerk, a town council, and seven dea- cons of the incorpoi*atcd trades. The united popula- tion of Old and New Aberdeen, amounted, in 1795, to 24,493; in 1801, to 27,508. It is situated ill W. Long. 2° 8'. N. Lat. 57° 9'; about 106 miles north-cast from Edinburgh, (/x) ABERDEENSHIRE, a county in the nortli of Scot- land, bounded by the German ocean on the east; by the counties of Kincardine, Angus, and Perth, on the C 2 20 ABE ABE south ; unci by the counties of Inverness, Moray, ami Bantl, on the west. It contains 85 parishes, 1 170 square miles; and, in 1801, its population was r23,Ob'2, being an increase of 6246 since the year 1755. The inland part of the county is, in general, wld, barren, and mountainous, tiiough the eye is Irequtntly relieved by large forests ot natural wood, which stretch along the sides of the hills. That part of the county which bor- ders on the coast is more fertile, though still suscepti- ble of great improvement. It slopes gradually from the central districts to the sea, where it terminates in ■A bold, rocky coast, occasionally rising into stupendous precipices, which arrest the attention of every travel- ler. The principal rivers which traverse the county, are the Dee, the Don, the Ythan, the Ugie, and the Cruden, which are all celebrated for the excellent sal- mon with which they abound. In the Ythan several pearls have been found, which sold separately at two and three pounds sterling. The shapes and the various connexions and grou- pings of the mountains of this county are still imper- fectly known ; and we have but little information res- pecting the geognostic structure and relations of the numerous rocks and minerals that render this part of Scotland so very interesting. It would appear from the observations that have been published, and the se- ries of specimens which we have had opportunities of examining, that the following rocks and simple mine- rals occur in Aberdeenshire. Rocks, Priinitrue rocks, granite, gneiss, mica-slate, clay slate, hornblende-slate, hornblende rock, primitive limestone, and sienite. Fldtz rocks, sandstone, and limestone. Simple minerals. Topaz found near Cairngorum ; rock-crystal, at Cairn- gorum and other places, falsely denominated topaz. Agates, common quartz, crystallized. Also amethyst, cyanite, mica, with radiated fracture. Precious beryl, calx-spar in various forms, gray manganese ore. From the granite, or sienite, quarries, 12,000 tons of that stone, valued at 8400/. are annually exported to Lon- don. The limestone is very abundant, but, from the scarcity of coal, it cannot be wrought to much advan- tage. The county contains many mineral waters, and tliose of Peterhead and Glendee are much resorted to for their medicinal qualities. The principal manufac- ture in the county was formerly the knitting of stock- ings and hose, in which great numbers of the common people were engaged; but the linen and sail-cloth ma- nufactures have been lately introduced with great success into Aberdeen, Peterhead, and Huntly. The valued rent of Aberdeenshire is 235,665/. Ss. Wcl. Scotch, and the real land-rent was lately estimated at 133,632/. sterling, (r) (to) ABERGAVENNY, an irregular, though beautiful town, in Monmouthshire, supposed to be the Gibba- nium of Antoninus. It is delightfully situated in a range of meadows, at the confluence of the rivers Usk and Gavenny, and incircled by several projecting hills, which abound in coal, iron ore, and limestone. The Gothic bridge over the Usk, consisting of 15 arches, is almost the only public building deserving of notice. On the south side of the town are the ruins of a castle which is celebrated in the history of Wales ; and to the east lies St Michael's Mount, in which there is a chasm, supposed by the vulgar to have been made at the cru- cifixion. It is resorted to by devotees, who carry off the sacred soil in handkerchiefs and carts, in order to enrich their fields. A few miles from Abergavenny lie the ruins of Llantony aljbey, imbosomcd in the deepest recesses of tlie black mountains.

Tnere was a re- ligious house here, which afterwards became a bishop's see. The Culdees, whose history is so obscure, had in this place a university, and a collegiate church, which is known to have subsisted towards the end of the thirteenth century. At Abernethy is a singular tower, of a circular form, 74 feet high, and 48 in circumfer- ence. There is one of the same construction at Bre- chin, and several similar ones in Ireland. Tiiese build- ings have been supposed by some to be watch-towers; others imagine that they were belfries tor summoning the people to prayers ; while a third class maintain, that they were penitentiary towers lor the reception of hermits.

In consequence of an insurrection in Ireland, his mother was obliged to retire with her family to Deny, in the siege of which she lost all her children except John, who was at that time living with a rela- tion. As no opportunity could be obtained of convey- ing him to his mother at Derry, he accompanied his friend to Scotland, in order to escape the fury of the Irish rebels. At the age of thirteen he went to the university of Glasgow, where he took his degree of A. M. ; and from this he removed to Edinburgh, to prosecute the study of divinity. He was ordained minister of the dissent- ing congregation at Antrim in 1 708 ; but being one of those who opposed the subscription of the Westmin- ster Confession, he and his friends were, in 1726, ex- cluded by the synod, who revived the act of 1705, re- quiring subscription from every candidate for the min- istry. From the great influence of the synod, his con- gregation began to desert him ; in consequence of which he accepted of an invitation from the congrega- tion of Wood-Street, Dublin, to which he removed in 1730. In this situation he continued for ten years, and enjoyed the respect and esteem of all who knew him ; but a sudden attack of the gout, with which he had been formerly seized, put an end to his life in Decem- ber 1740, in the sixtieth year of his age. As a preacher Mr Abernethy was much admired ; and his talents for public speaking gave him great in- fluence in the synod. In private life he was distin- guished by vivacity of disposition, urbanity of manners, and by the whole train of domestic virtues. The independence of his mind, and his attachment to civil and religious liberty, were conspicuous in the exertions which he made to emancipate the Irish dissenters from the operation of the test laws, those striking proofs of the bigotry and illiberal policy of our ancestors. The most celebrated of Mr Abernethy's works is his Discourses on the Divine Attributes. Two ABEllKATJO^. 21 volumes of his ''icrmons were published in 1748, and other two in 1757, to which is preiixcd an account of his liic, supposed to be written by Dv Duchal. He also left Ijelund hun a diary of his life in six volumes 4to. (to) ABERRATION, in Astronomy, is a change in the positioii of the fixed siars, arisintj from the progres- sive motion of light, combined with the annual motion of the earth, by means of wliich they sometimes ap- pear twenty seconds distant from their true position. This apparent motion of the lieavenly bodies was de- tected in 1725, by our celebrated countryman Dr Hrad- Icy, and is one of the most brilliant discoveries whicli has enriched the science of astronomy. During the seventeenth century, the supporters of the Copernican system laboured to prove the annual motion of the earth, by detecting a change in the posi- tion of the fixed stars. They supposed, that if ASBD was the earth's orbit, A its position in December, B its position in June, and S any fixed star, the observer on the earth at A would see the star S, in the point >i of the heavens ; while the observer, when the earth came to B, would see it in the part m, the star having appear- ed to move through the arch m ?i, equal to the angle ASB, or the angle subtended at the star, by the diame- ter of the earth's orbit. They saw, that when the star S was in the pole of the ecliptic, or cqui-distant from A and B, this angle was a maximum ; for the angle AsB, subtended by AB, at any other star s, is evidently less than ASB, and therefore they selected a star nearest to the pole of the ecliptic, with the hope of detecting the earth's annual parallax, and thus putting to silence the abettors of the Ptolemaic and Tychonic systems. With this view, Dr Hooke made a number of obser- vations in 1669, on y Draconis; and he informs us in his Attcmf-it to firove the Motion of the Earth from Ob- seroations^ that he found this star 25" more northerly in July than in October. These observations, how- ever, were not accurate, as afterwards appeared from those which were made by Dr Bradley upon the same star. About the same time, M. Picard, when going to Uraniburg to determine the difference of longitude be- tween it and Paris, had observed the motions of the pole star, and found a variation amounting to nearly 40" in a year. As this variation was in a direction opposite to that which should have been produced by the paral- lax of the earth's orbit, Picard confessed himself unable to account for it; but insisted that the error in his ob- servations at Uraniburg could not amount to 1 0". Col- lect. Observat. Paris, 1691. In 1680, Mr Flamstead made a number of observa- tions on the pole star. He found that its declination was 40" less in July than in December ; and falling into the same error as Dr Hooke, he endeavoured to show that this variation was the effect of the annual parallax. Cassini and Manfredi nmintained, that the motion of the earth could not account for the observed variation ; but none of them were able to give an adequate explana- tion of the annual changes which every astronomer ob- served in the position of the stars. In order to confirm the observations of Dr. Hooke, Mr. Samuel Molyneux erected an instrument, about the eiKl of November, 1725, constrvicted by the cele- brated Mr Graham. He made his first observation on y Draconis on the 3d December, nri- ' , r-p; ated it on the 10th, llth, and 12th of the same month; but this was done rather with tlic intention of uyuig the instru- ment, than detecting any parallax in the stars, as no sensible alteration ol the parallax could liave been ex- pected at that season of the year. Dr Bradley was at this time on a visit to Mr Molyneux at Ke^, (Brad- ley's Letter to HuUey, I'hil. Trans. 172B,) and being anxious to try the new instrument, he oljservcd y Dra- conis on the 17th December, and found that it was more southerly tiian it had been when Mr Molyneu.x observed it about the beginning of the month. This variation tiiey naturally ascribed to the inaccuracy of their observations; but upon rei)eating them on the 20th of December, they tound that the star was still continuing to move southward. The direction of this motion, however, being opposite to that which would have been produced by parallax, tliey were more per- plexed than belore; and, as they were satisfied of the accuracy of their observations, they began to suspect the correctness of the instrument. But being convinced, from many trials, thattheir suspicions were groundless, they continued to observe the star, and found that on the beginning of March, 1726, it had moved 20" south since the commencement of their observations ; — that it remained stationary till the middle of April, when its motion was northerly; — that it continued to move northward till the month of September, when it again became stationary, havuig advanced 20" farther north tlian it was in June ; and that it again resumed its mo- tion towards the south. The law of the variation in the motion of the fixed stars being thus determhied, Dr Brad- ley became very anxious to discover its cause. In his first speculations on trhis subject, he ascribed these changes to the nutation of the earth's axis ; but this hvpolhesis was soon abandoned; for he afterwards saw, that stars which, from the equality of their polar distances, ought to have had the same nutation, sustained very different changes of declination. Eager to investigate these curious phenomena. Dr. Bradley determined to erect an accurate instrument for himself at Wanstead, and, with the assistance of Mr Graham, it was ready for use on the 19th August, 1727. After a number of interesting observations, con- tinued for the space of a year, from which he satisfied himself completely respecting the general laws of the phenomena, he again directed the whole energy of his mind to discover their cause. A change in the direc- tion of the plumb-line which adjusted his instrument, and an elevation of the stars by the refraction of the atmosphere, soon occurred to him as sources of ex- planation; but, being inadequate to account for the phenomena, they were as quickly rejected. In this state of perplexity, the discovery of Roemer concern- ing the successive propagation of light, came into his mind, and he instantly saw, that all the phenomena which he had observed, might be occasioned by the motion of the earth in its orbit, combined with the suc- cessive propagation of light. In order to understand this, let us suppose, that a particle of light, coming from a star, is at A when the eye is at B, and that light moves through the space AC in the same time that the eye, by the annual mo- tion of the earth, moves tlirough BC. By taking any point E, and drawing ED parallel to BA, tl»e particle of light v/ill evidently be at D, when the eye has moved to E, for CD : CA=CE : CB (Euclid, VI Prop. 2.) Let us now suppose, that AB is a telescope or tube, moving parallel to itself, then it is manifest that the 22 ABERRATION. particle of light will iilways appear in the tube, and con- sequently the star from whicli it comes will be seen in the direction of the tube ; that is, in the directions B A, ED, CF, when the eye is at 15, E, and C, successively : But the l*ht from tlie star comes in directions parallel to AC, because the real place of the star is in that direc- tion; consequently the aberration, or the dirCercnce be- tween the real and apparent place of the star, will be the angle ACF, which may be computed tiigonomctri- cally, by having the velocity of light, the velocity of the earth in its orbit, and the place of the star.

La Place has found for the entire aberration, 37" 5, a result exactly the same as that which Bradley deduced from a great number of delicate observations on the fixed stars. From this curious coincidence, La Place concludes, that the velo- city of light in all the space comprehended by the earth's orbit, is the same as at the circumference of this orbit, and that the same thing holds with regard to the orbit of Jupiter.

The time, for example, in which light moves from the sun to the earth, is 8' 8" ; and during this time, the geocentric mo- tion of the sun in longitude, is 20", consequently 20" is the sun's aberration in longitude.

(w) ABERRATION, in Optics, is of two kinds ; Aber- ration of colour, or refrangihilitij, sometimes called Cliromatic aberration ; and Aberration of sjihericity, or apherical aberration. When a beam of white light falls upon a spherical lens, the violet, or most refrangible rays, cross the axLs at a point nearer the lens, than the red or least refran- gible rays. The distance between the point, where the red ray intersects the axis, and the geometrical focus, is called the longitudinal chromatic aberration of the red ray ; and its lateral chromatic aberration is measured by a line perpendicular to the axis, and drawn from the lo- cus till it meet the refracted ray. In consequence of the spherical figure of the lens, the red, or any other kind of rays that pass nearest the centre of the lens, meet the axis in a point nearer the lens than those whicli pass at a greater distance from the centre. The distance between this point and the geometrical focus, is called the longitudinal s/iherical aberration ; and the distance of the geometrical focus from the refracted ray, in a line perpendicular to the axis, is called the lateral s/iherical aberration. The same kind of aberration is produced by reflection from sphe- rical specula. When the speculum is parabolic, and the point from which the rays proceed infinitely distant, there is no aberration, as all the rays meet in the geo- metrical focus. There is also no spherical aberration for parallel rays in the meniscus lens AB, Fig. 4. when its convex surface ACB, is part of a prolate spheroid, and its concave surface AEB, formed with a radius less than FC, the distance between the vertex of the lens and the fatrhcr focus of the spheroid. If the lens be pla- noconvex, as in Fig. 5. having its convex surface part of a hyperboloid, whose major axis is to the distance between the foci, as the sine of incidence is to the sine of refraction out of the solid into the ambient medium, the parallel rays RR will be refracted to the farther fo- cus F, without any spherical aberration. In order to find the lens of least aberration, M. Klin- genstierna has given the following general theorem, a r(m-\-4 — 2;»2) ..(./•('2w=-f ;«) . , • , ■ , ■7= ji — —; — - — . ;^ ; — -. in which a is the radius * y('"+4 — 2m2)^r(2/H--f»;) of the surface of the lens next the object ; b the radius of the other surface ; m the index of refraction, or the ratio of the angle of incidence to that of refi-action ; r the distance of the radiant point, and ythe focal distance • 3 of the refracted rays. When )n =— and r infinite, -we a 1 , a . haveT=T; and when m= 1686, we have 7= infimte,or 06 t/ a plano-convex lens. The spherical aberration of lenses being very small, when compared with the chromatic aberration, the con- fusion of images arising from the latter is a great ob- stacle to the perfection of refracting telescopes. The method of removing this confusion to a certain extent, by a combination of lenses of different refractive and dispersive powers, first discovered by Mr Dollond, gave rise to the achromatic telescope, an instrument which has exercised the genius of the most dis- tinguished philosophers.

In the island of Formosa, we arc- told that no woman is allowed to carry a child to the full time, till she arrives at the age of thirty-five years. The American Indians, likewise, permit at- tempts to procure abortion ; and the Africans, m or- der to conceal an illicit connexion, sometimes use an infusion of a species of grass to destroy the foetus. In Guiana, a different plant is used for the same purpose. In the West Indies, the Negroes sometimes make similar attempts ; though, from promiscuous inter- course, and other causes, abortion frequently happens without any effort on the part of the mother. However criminal this practice may be, it is far less so than the custom of some other countries, where the child is allowed to come to the full time, but is suf- focated whenever it is born. Such is the case in the South Sea Islands. In China, new born children are exposed on the streets, or thrown into the water, with- out compunction. Other savages, still more barbarous, inter the living child with the dead mother, when she happens to die soon after delivery.

(/) ABOU-IIANNES, or Fatheh John, the name of a bird found in Ethiopia, and supposed to be the Ibis, which the Egyptians formerly held in high veneration, but which no longer exists in that country. Mr Bruce founds this opinion upon the resemblance between the abouhannes, and the embalmed bodies ot the Ibis which have been preserved by the superstition of the Egyp- tians ; and likewise upon its similarity to the figures of the ibis which appear among the hieroglyphics on the ancient obelisks. According to Cuvier, who calls it ^'umenius Ibis, it is the same as the Tantalus F.thiojncus of Latham, and the Tantalus Pavoninus oi'Wz.'aK.

(w) ABOUKIR, a town in Lower Egypt, situated be- tween Rosetta and Alexandria, at the distance of four leagues from tlie latter, and celebrated by the brilliant victory gained by Admiral Nelson over the French fleet in the bay of Aboukir, in 1 798 ; and by a battle in 1799, between the French army and a body of Turks and Arabs, who had landed in the bay, and made them- selves master of the redoubt and the fort. Bonaparte attacked them on the 26th of July, and, after a bloody engagement, obtained possession of the peninsula. The fort held out for the space of eight days, when it capi- tulated, and exhibited nothing but a heap of ashes. From some inconsiderable ruins, Aboukir appears to have been the site of an ancient city ; and its situation with respect to Alexandria warrants the supposition, that it is Canopus, one of the most ancient cities in the world. The town is built upon a rock ; and if we may give credit to Pliny, was formerly a small island. About two miles from Aboukir are the ruins of a town upon the sea coast, and partly under water, supposed to be the Ta/iosiris Parx'a of the ancients. The for- tress of Aboukir, which is not strong, is governed by a Torbashi, who collects a toll from those who cross the ferry. E. Long. 30° 18'. N. Lat. 31° 39'.

He was confessor to Alphonso V. king of Portugal, and Ferdinand the Catholic ; but having amassed great wealth, his over- bearing and ambitious disposition displayed itself in his oppression of the poor, and in his insatiable desire of the most illustrious titles. His unrelenting hosti- lity to the Christian faith, combined with the arrogance of his temper, was one of the chief causes of the per- secution in 1492, in which he and all the Jews were driven out of the Spanish dominions. After his expul- sion from Spain, he resided at Naples, Corfu, &c., and died a. Venice in 1508. The reverses of foilune which he experienced on accoimt of his religion, soured his dis- position, and generated that implacable liatred against liie Calliolics, which is displayed in all his writings.

His fallier was an idolater, like the rest of his countiymen ; but Abraham having renounced heathenism, they left Ur together, and on their way to Canaan, resided at Ilaran, in Mesopotamia. Terah having died at Haran, the Lord commanded Abraham to go towards Palestine, at that time inhabited by the Canaanites, promising tO' make of him a great nation ; and to raise up to him an ofi'spring, in whom all nations of the earth should be blessed. Firmly believing the Divine promise, he took with him his wife, and Lot, his brother's son, with all his servants and cattle, and settled in Canaan, where the promise made to him was renewed, confirmed, and enlarged. The facts in this and the subsequent part of his history are so well known, and narrated with such interesting simplicity by Moses, that it is unne- cessary to give even a general detail of them, (rf) ABRAXAS, or Abrasaxas, a mystical word, sup- posed by St Jerom and other writers to denote the supreme God of the Basilidian heretics, though it is the opinion of Irenseus that it was the first of their 365 heavens, or the prince of the angels that inhabited them. According to Beausobre, it is derived from aofo5 and trau, which may be made to signify magnifi- cent Saviour. See Montfaucon\ Palxograjihia Graca, lib. ii. cap. 8. The term Abraxas is also the name of small statues of plates of metal or stones, on which are engraven fi- gures of the Egyptian deities, combined with Zoroas- tric and Jewish symbols, and a strange mixture of He- brew, PhcEnician, Greek, Coptic, and Latin characters. In the Palaeographia Graeca of Montfaucon, may be seen engravings of a great number of these gems, which he has arranged into different classes. Their origin and use have been much disputed among anti- quarians. Montfaucon is of opinion, along with St Jcrojn, that Abraxas was the god of the Basilidians ; and that the gems of that name were amulets worn by these and other heretics in the early ages of the church. Beausobre and Lardner, however, have examined care- fully the various specimens given by Montfaucon, and have shown pretty clearly, that they are of heathen origin ; that Abraxas was not the god of the Basili- dians ; that this term signifies nothing but the sun, which was never worshipped by these heretics ; that the figures are for the most part Egyptian; that there is no evidence of their having belonged to the Basili- dians ; that those which have the words lao, Sabaoth, kc. upon them, were the works of magicians who never professed the Christian faith ; and that some of these figures derived their origin from the Sinonians and Ophites, who did not even profess Christianity. Treatises on the abraxas have been published by Mo- carius and J. Chiflet, to whom Montfaucon has been indebted for many of his figures. Several of these gems are in the National Library at Paris, Beauso- ABR ABR 27 hrc's History of the Manichcans, vol. ii. p. 55 ; and Lardncr's iVork.i, vol. ix. p. 190. (iv) ABRIDGMENT, in literature, tihe reduction of a ^vork into less tlian its original compass; which i.s an an of infuiitely greater utility than we are geneially disposed to admit. It ^\ as in the fiflh century that the practice of aljridging came into general use. When the taste for literature began to decline, the number of original compositions was greatly diminished, and a swarm of abridgers su]iplied their place, and gratihed the indolence of the public by abridgments of the pon- derous and almost forgotten volumes of antiquity. Some of these abridgers employejl, with a few changes, the expressions of the authors themselves; others selected their facts from various sources, and clothed them in their own lant^iiage; while a third class collected the most valuable passages from authors who wrote upon the same subject; and by their union formed an inte- resting work, and thus rescued from oblivion some of the most valuable fragments of antiquity. In this way several huge works were greatly improved by abridg- ment ; among which we may mention the voluminous history of Trogus Pompcius, of which Justin has fur- nished such an excellent epitome. At no period, per- haps, has the necessity of abridging been more conspi- cuous, or ought to be more earnestly inforced, than at the present. In this age, it would appear, as if each author thought his subject inexhaustible ; and, not con- tent ■vAjth disquisitions on points truly important to science, he forces into notice those which never merit- ed consideration, as if it were possible to convert dross into gold. We regret that several such attempts have been too successful ; and we have to lament the depra- vity of public taste, which must always result from such pernicious examples. We lay it down as indisputable, that the better an author understands his subject, he will reduce it into the smaller compass; because each head having re- ceived the discussion peculiar to itself, becomes a co- rollary. There cannot, therefore, be a more estimalile property, than that of expressing much matter in few words; and when an author fails in this, we can ascribe it only to ignorance of his subject, or the want of skill in composition. At the same time it is true, that many, unacquainted with logical deductions, wander into pro- lixity, from inattention to the strong positions in which an argument may be placed. The ponderous volumes daily ushered into the world, attended by every mark of pedantry, do little credit to literature. It is no uncommon occurrence to find scarcely one-fourth of them occupied by the subject announced, while the rest is filled by the author with a commentary on himself, in his preface, introduction, and appendixes ; or in that most convenient, and least suspected of all receptacles, — innumerable notes. Those who employ themselves in the abridgment of books, are often engaged in a useful occupation : for they have not only the choice of the work, but the se- lection of the matter. It is not easy to point out the specific line which they should follow; for this must, in general, be regulated by the work itself. But the principal points to be considered are, first, the precise object of the work ; and, secondly, what parts of it most forcibly tend to support the views of its author. When an abridger has made himself fully master of these, he may retrench superfluities which have escaped the au- thor's notice ; and may be able to present the work in a more satisfactory form than was originally done by the author himself. The following hints to abridgers are given by the elegant author of the Book of Maccabees, in a preface to that history : " All these things, I say, being declared by Jason of Cyrene, in ^vc bouk-H, wo shall essay to abridg-f in one volume. We shall be careful that they wlio read may have dttight; that the y who are desirous to connuit to memory may liave ease; and that all hito whose hands it comes may have profit." " To st and upon e-vei-y point, to go over things at large, and to be curious in jiarticulars, belongs to the first author of the story ; but to use brevity, and avoid much labourmg in the work, is to be granted to him who will make au abridgment."

(c) ABRIZAN, the name of a festival observed by the ancient Persians on the 13th day of the month Tir. li has been partly adopted by the Mahommedans,and, hap- pening near the time ot the autumnal equinoxes, it ap- pears to have been preparatory to the rainy seasons.

The Abroma Augusta is a native of various parts of India, New South Wales, the Philippine Isles, &c. It has been found by Dr Roxburgh to be particularly ex- cellent for making cordage, &c. and has thence been called Indian flax. The fibres employed for this pur- pose are abundantly interwoven with its bark, and remarkable for their beauty, fineness, and strength. They are separated from the parenchymatous sub- stance, by maceration in water, from four to eight days, £cc. See Alcmoirs of the Society of Arts for 1804, which contains Dr Roxburgh's paper on this subject. See Botany, (w) ABRUS, a genus of plants of tlve class Diadelphia, and order Decandria. See Botany, (to) ABRU2ZO, a province of Naples, which derives its name from the city of Geramo, anciently called Abruz- zo. It was the Samnium of the ancients, the country of the Samnites, who were distinguished by their valour, their civilization, and Uie wars which they waged with the Romans during seventy years. Abruzzo is divided by the river Pescara into two parts, called Ulterior and Citerior Abruzzo, of which Aquila and Chieti {Theate') are the capitals. This province is naturally fertile and productive, and affords its inhabitants more than a suf- ficient supply of corn, rice, fruit, oil, and wine, besides saffron and hemp; but from the want of convenient harbours and good roads, there is no encouragement to exportation. The country is therefore in general desolate, and the peasantry poor and uncomfortable. The climate is cold, though salubrious ; the country being traversed by the Apennines, which are always covered with snow. Among the stupendous mou.ntains which continually arrest the eye of the traveller, Mon- te-Corno and Majella are the most interesting. The former presents a rugged and broken front, and is al- most inaccessible, while the declivities of Majella are clothed with rich fields, and an immense variety of plants. These mountains are infested with wolves and bears, which commit great depredations in the winter. The deer and the tiger-cat, or lynx, are. also found in the woods. In the province of Abruzzo is the cele- D2 28 AB8 ABS bratcd emissary of the emperor Claudius, for draining the beautiful and romantic lake of Celano, anciently called Fucinus. This emissary is a covered under- ground canal, three miles long. A great part of it is cut out of the solid rock, and the remaining part is supported by masonry, with large openhigs to admit the light and the air. According to Suetonius, 30,000 men were employed for eleven years in this stupendous work, which was intended to convey the superfluous waters of the lake Celano into the bed of the river Ga- rigliano. The emissary being now hlled up with rub- bish, the waters of this lake, which is above thirty miles iu circumference, are making rapid encroach- ments on the rich and cultivated plains which sur- round it; and unless the canal is cleared and repaired, the lake will soon inundate the nuhierous villages which smile upon its banks.

His sister Tamar having been ravished by Anuion, her elder brother, Absalom took her under his protection ; and, having waited two vears for an opportunity of revenging this injury, procured the assassuiation of Amnor:, at a feast, to which he had invited the whole royal family. On this, he fled to his grandfather, and continued with him in Geshur three years ; after which, he was restored to David's favour. But, looking on himself as presump- tive heir to the crown, he soon fonned tlie design of dethroning his father, and succeeded in gaining the affections of many of the people. Through the influ- ence of Hushai, David's friend, who counteracted ihe counsels of Ahitophel, Absalom's adviser, he delayed attacking the king's army, till they were prepared to receive him. In consequence of this, his forces were defeated with great slaughter, and he himself, having fled into the wood of Ephraim, was caught by the hair when passing under a large oak. Here he was found hanging by Joab, who thrust him through with tiiree darts, though David had ordered his life to be spared. See Univ. Hist. v. iv. p. 73 — 79.

It depends on the power of association, confirmed by habits of abstruse and solitary thinking. It is, of course, the failing of literary men ; of tliose who are accustomed to silent reasoning, and \o view their opinions in all their consequences and aspects. A long train of thought passes through the mind, and the attention is engaged so completely, that objects witliout, which tuake an impression on tlie senses, arc either not perceived, or hare not sufficient power to Ijreak the line of associated ideas; or, per- haps, have no such relation to any of them as to restoi-e the perceptive faculty to its exercise. A clock may strike, or a friend may litter something wliich ought to interest us, and both may be unheard or neglected. " A man is mentioned, in Darwin's Zoonomia, who, during the paroxysm of a reverie, was reciting some lines from Pope, one of which he had forgotten. It was several times inefi'ectually shouted in liis ears, till at length, after much labour, he recollected it by his own eflbrts." See Mr Grant's paper on Jievcrie, in the Manchester Memoirs. The absence of mind, which we are speaking of, is the failing of those likewise whose imaginations are active, and whose memories are good; who indulge ui scenes of fancied happiness, and fly from the miseries around them to those ideal joys, from which all sorrow is excluded. They contemplate, in their reveries, only the fair side of objects. Every adventure in which they engage is successful ; every incident that occurs, is improved to their benefit; every sound is harmo- nious, and every colour is pleasing to the eye. This exercise of the imagination differs from a dream; be- cause the individual is really awake, and exerts such x power over his thoughts, as to banish all evil from the happiness which he enjoys, and to satiate himself with unmingled pleasure. The exertion of this power must be considered as voluntary, at least in its first or ear- liest endeavours, though the ideas appear to follow each other in the mind, without any control or direc- tion from the will. A want of attention to external objects, that are pre- sent, is often the effect of a strong impression, made upon the mind. This impression, and the incidents and appearances which gave rise to it, overpower the faculty of perception, withdraw it from the organs of sense, and, engrossmg the whole of the thinking prin- ciple, render us incapable, for a while, of turning the mental eye to any thing without. Thus, an execution; a contest between two powerful ai-mies ; a madhouse, with its wretched inhabitants ; — one or any of these ob- jects may force itself so strongly upon the attention, that the idea of it will continue in the memory, even against our wishes, and produce a train of reflections, which will absti"act us entirely from the occurrences around us. These sticceed one another without our no- tice or concern. We have heard of a man, who had witnessed the execution of a person, with whom he was connected in business : and such was the impression that the last struggles of the criminal made upon him, that, for a whole week, he neither spoke nor acted as he had done before. He appeared to be absorbed in tliought, and at night his dreams were characterized by the objects which had taken possession of his mind. Where absence of mind rises to such a height as to constitute a disease, it is for the most part connected with some disorder of the body ; and is to be cured by exercise and change of place, by a relaxation from ha- bits of abstract thinking, and by the various remedies for counteracting any undue irritability or depression of the nervous system. (A) ABSOLUTE Number, in algebra, is the known quantity, or number, which forms one of the terms of an equation. Thus, in the equation x" — 5j:-=8, the absolute number is 8. {iv) ABSOLUTION, in tjje canon law, is that act by ABS ABS 29 xvhich a Roman Catholic pi-icst forgives the sins of those, who, by confession and repentance, seein to deserve it. The iorni of absolution, employed by Tctzei, whose sale of indulgences and absolutions paved the way for llie Reformation, may be seen in Robertson's Histunj »f CharUis K. vol. ii. p. 117. (w) ABSORBENTS, or Absoubing Vessels, are mi- nute and transparent vessels, found in all animals, which absorb, or imbibe, any liuid with which they come in contact, and carry them into the circulatmg blood. They are divided into Lactcals and Lym/i/iatics, accord- ing to the liquids which they convey; the former con- veying from the intestines a milky liquid, called the chjle, and the latter conveying lymph, a thin pellucid liquor, from all the interstices of the body. The lac- teal vessels were discovered by Erasistratus, of the Alexandrian school ; and the lymphatics, by Rudbec, a Swede, and Bartholinc, a Dutch anatomist, in 1651. The opinions of the English anatomists on the absorb- ent vessels, have been recently controverted by M. Wal- ter, a German Physician, in a curious paper in the Me?)!, de I'ylcad. Btrtin, 1786, 1787. He maintains, that the lymphatics are properly the absorbing vessels, and that, in all parts where. there is a cellular substance, they partake with the veins in the office ol absorption; that they absorb the chyle in conjunction with the Vena Portarum ; that tliey alone absorb the milk in the breasts of women ; and that the veins, on the other hand, p-sr- form the office of absorption m all the cavities of the body, and over all its surface.

Sometimes '.t '.va') culled India; a vague appellation, which seems to have been given indiscriminately to those eastern na- tions which were most remote, or least known. Some- times it was denominated Atlantia and Etiuria ; and, in the more distant periods of antiquity, C< fihenia. Its most common appellation, however, was ylbasenc, a word not unlike its modern names, j^bassia and .4byssinia. On the other hand, Persia, Chaldea, Assyria, and other Asiatic countries, were sometimes styled Ethiopia; and all the nations along the coast of the Red Sea were called promiscuously Ethiopians, or Indians. There was one country, however, to which the name Ethiopia was thought particularly to belong, and which was therefore called Ethiopia Propria. It was bounded on the north by Egypt, extending all the way to the less cataract of the Nile, and the island Elephantine ; on the west, by Libya Interior; on the east, by the Red Sea; and on the south, by imknown parts of Africa. The geo- graphy of ancient Ethiopia is involved in much obscu- rity : indeed no accurate infomiation can be expected concerning the interior of a country, of which even the general outlines have not been ascertained with preci- sion. Ancient writers agree in describing it as very mountainous, though they mention none of its moun- tains of any consequence, except Garbata and Elephas, which are generally supposed to answer to the moun- tains of Tigre. A great variety of nations were assigned to ancient Ethiopia, distinguished by names expressive either of some personal peculiarity, or of their particular mode of living. Among these were the Blemmyes, said, probably on account of the shortness of their necks, to have no heads, but to have their eyes, mouths, and noses, in their breasts ; the Troglodytes, scarcely supe- rior to the brutes ; the Struthiophagi, or ostrich eaters ; Acridophagi, or locust eaters ; Chelonophagi, who fed on tortoises ; Elephantophagi, who lived on elephants ; Agriophagi, who ate the flesh of wild beasts ; Anthro- pophagi, or man eaters, now supposed to have been the Caffres, and not Ethiopians ; and the Macrobii, a power- ful nation, remarkable for their longevity. The remote situation of this counti^ rendered it a proper scene for poetic fiction. To this, perhaps, rather than to his historical accuracy, we must ascribe the cha- racter which Homer has given the Ethiopians as the justest of men, with whom even the gods deigned to associate in the familiarity of convivial intercourse. Concerning their general customs, however, we receive from ancient historians more certain information. In many of these they differed widely from all other na- tions, and particularly in the manner of electing their kings. The priests, in whose hands the chief power was lodged, chose the most reputable men of their or- der, and drew around them a circle which they were not allo^vcd to pass. A priest entered the circle, running and jumping like a satyr. Those, enclosed as candidates for the sovereignty, endeavoured to catch hold of him, and the person who first succeeded, was hailed as the vicegerent of Heaven, intrusted by Providence with the government of the nation. The sovereign, thus elected, began immediately to live after the manner prescribed by the laws. He was regulated, in all his conduct, by the customs of the country over which he presided ; and, in dispensing rewards and punishments, was obliged rigidly to adhere to the original institutions of the state. A subject could not be put to death by the royal order, though capitally convicted in a court of justice. An of- ficer was sent to him with the signal of death ; and the criminal, shutting himself up in his house, became his ABYSSINIA. 35 own executioner. The priests of Mcroe, who conferred the royal oflice, assumect an ai'bilrary power over the sovereign, and even limited at pleasure the period of his reign. When a king had dtspleased tliem, or when they wished to give him a successor, they despatched a cou- rier to order him to die. To oppose a mandate, which was represented as proceeding from the gods, would have been regarded as the most heinous of crimes ; and the kings, though under no obligation to obedience but what tlicir o^^n superstition imposed, implicitly com- plied with these tyrannical awards. At length Erga- menes, who reigned in the time of Ptolemy the Second, and who was instructed in the philosophy of the Greeks, had the coiu'age to shake off this iniquitous yoke. lie led an army against Meroe, put all the priests to the sword, and instituted a new worship less arbitrary and oppressive. Among the friends and adherents of the king, the singular custom prevailed, of suljjecting them- selves to every personal infirmity, with which, by acci- dent or malady, he happened to be afflicted. It was ac- counted base and disloyal to refuse to share in all their monarch's sufferings, since men are induced, even by the sentiments of common affection, to appropriate tlie distresses or happiness of their friends : to die with their sovereign, was considered a most glorious testimony of their fidelity. A prince, in whose safety his subjects were so nearly interested, must have been very secure against the machinations of treason. Their funeral ceremonies were peculiar and remark- able. The body, after being salted, was put into a hol- low statue, resembling the deceased ; and the statue was placed in a niche, on a pillar erected for the piu'pose. These statues were made of gold, silver, or earthen ware, according to the circumstances of the deceased. The body was kept for a year in the houses of the near- est relations; who, during that time, offered sacrifices and first fruits to their departed friend. When the year had expired, the niche was fixed in a place, set apart .for that purpose near the town. In war, the Ethiopians made use of bows and arrows, darts, lances, and several other weapons, which they managed with great strength and address. Their ar- .rows were very short, pointed with sharp stones instead of iron, and dipped in tlie virus of serpents, or some other poison so powerful, that the wovmds ^^■hich they inflicted were followed by instant death. Their bows were four cubits long ; and to bend them required a degree of strength which no other nation could exert. Like the Parthians, they retreated fighting; and, whilst retiring at full speed, discharged volleys of arrows with the utmost dexterity and effect. Such were some of the customs by which those Ethiopians were distin- guished who lived in the capital, and who inhabited the island of Meroe, and that part of Ethiopia which was adjacent to Egypt. There were many other Ethiopian nations, some of which cultivated the tracts on each side of the Nile, and the islands with which it is interspersed ; others inhabited the provinces bordering on Arabia; and others dwelt nearer the centre of Africa. All these people had the negro features; flat noses, black skins, and woolly hair. They were savage and ferocious in their appearance, brutal in their customs and manners. They are now known by the name of Shankala; and still retain their primitive rudeness and barbarity. The inhabitants of the coimtry above Meroe made re- markable distinctions among their gods. Some they supposed to be of an eternal, incorruptible nature, as the sun, til*; moon, and the universe ; others, born of men, had acquired divine honours by U\eir virtvies, and their benefactions to mankind. But there were some Ethio- pians wllD believed in no gods ; and, when the sun rose, they fled into their marshes, execrating him as their crudest enemy. These people differed likewise froni other nations in their manner of honouring the dead. Some thought it the most honouralile burial to throw their bodies into the river: others placed them in niches in their houses, that their children might be roused, by the sight of their ancestors, to virtuous achievements-; and tliat the more advanced in life might retain their deceased friends in their memory and affection. To swear with their hand laid upon a dead body, was their most sacred and inviolable oath. Their monarchies were, in general, elective ; and their ideas of the quali- ties requisite in a sovereign, exhibit, in a most striking light, tiie sunplicity of these barbarous tribes. Some of them conferred the crown on themost handsome man of the nation ; thinking it proper, that dignity and a fine person, in their estimation the best gifts of heaven, should always be united. Others preferred, as their sovereign, the most vigilant shepherd, from a reasonable persuasion, that he would prove likewise the most faith- tul guardian of his people. In some districts, the richest was exalted to the throne, because he had the most am- ple means of doing good to his subjects ; while others thought the strongest most intitled to royal power, inas- much as he was ablest to defend them from their ene- mies. Modern Abyssinia was scarcely known to Europeans till it was discovered by the Portuguese towards the end of the fifteenth century. Before that time, indeed, a few individuals had occasionally gone to that country from Italy ; but the information which they communicated concerning it was so vague and obscure, that even its situation was unknown. An embassy from the king of Portugal arrived in Abyssinia in the year 1520. Covil- lan, who had been delegated several years before as ambassador from the same coiu't, was, according to the usual policy of the Abyssinians towards strangers, de- tairtfed in the country, though treated with the utmost kindness and respect. His knowledge of Abyssinia must, of course, have been extensive. He was still alive when his countryman, Roderigo de Lima, came to Shoawith his suite ; and Francisco Alvarez, one of the chaplains to Roderigo's embassy, who, besides residing six years in this kingdom, possessed the additional ad- vantage of Covillan's information, gave the first regular account of Abyssinia. Mr Bruce, who certainly had op- portunities of observation at least equal to those of Al- varez, has questioned the authenticity of his narrative. But the truth is, as Mr Bruce himself has conjectured, that several fabrications were published in Alvarez's name, by persons who had probably never travelled out of their own country. Damian Goez tells us, that he had seen a journal written by Alvarez, very different from that which had been given to the public ; and the writer of tliis article has been favotued with the sight of extracts from the original manuscript, taken by a lady, highly respectable for her rank and accomplishments, while residing in Portugal, which, in everything essen- tial, coincide with the narrative of Bruce. In the reign ofYasous I. amission to Abyssinia was concerted by Louis XIV. of France. The introduction of the mission- aries was facilitated by a dangerous scorbutic disorder, which had attacked Yasous and his son, for which they E2 36 ABYSSINIA. wished U) have tlic advice ol' a European pliysiciaii. Through the influence of the Frencli consul at Cairo, tliis honour was conferred on Charles Poncet, a French chemist and apothecary, whom father Brevedenlfa pious and intelligent Jesuit, attended as his servant, ^'oncet arrived at Gondar on the 21st ol July, 1699, and,*having completely succeeded in curing his royal patients, set out on the following summer on his return for Europe, by the way of Masuah, and, arriving in safety, published a distinct and copious account of his journey. The ac- counts of the Jesuits and Portuguese, with Mr Bruce's Travels, are the only sources of our information respect- ing Abyssinia. To this latter gentleman, whom, not- withstanding the vexatious cavils of ignorance and pre- judice, we scruple not to pronounce one of the most deserving of modern travellers, the world is indebted, not only for a clear and comprehensive view of the geo- graphy of that extensive empire, but for an interesting detail of its history, institutions, and manners. The progressive geography of this country cannot easily be traced. Its boundaries have varied at differ- ent periods, according to the power and conquests of its sovereigns. In the days of Amda Sion, who began to reign in the year 1312, it extended from the 16th to the 7th degree of north latitude, and from 44° to 35° of east longitude from Greenwich. The most numerous, and the ruling inhabitants of this extensive country, were the descendants of a colony from Yemen, or Arabia Felix. The aboriginal tribes were reduced to dependence, or exiled to the mountains ; the Shankala wandered around the frontiers, which, as in all barbarous kingdoms, were ill defined, and changed almost every year with the vary- ing fortime of war. Wandering Arabs, and Shankala, enclose Abyssinia on the north. The former migrated from the opposite coast of the Red Sea, at a period sub- sequent to the time of Mahomet. The latter are the na- tive inhabitants of ancient Ethiopia, and occupy a more extensive territory than all Abyssinia and Nubia toge- ther. They encircle the whole length of Abyssinia on the west ; join the Galla on the south, and coast down the White river to Sennaar, where they rule under the name of Fungi. To the north, where they arc mingled vWth the Bejaand Belowe Arabs, they are called Dubena. It seems to be the same race, which, in the ridge of moun- tains to the east of Tigre, is known by the appellation of Doha. The Beja are a wandering tribe in the range of moiuitains north of Souakem ; the Taka Halanga appear to be of the same nation ; and it is conjectured, with much probability, that the Belowe are the same with the Alba- nim, a race of degenerate Christians. Abyssinia is divided into several provinces, each of which contains many small districts, called in Gcez, Midr, or The Land. Beginning from the north, the natural or- der of the provinces is as follows. 1 . Passing from Mazaga, the low country, inhabited by the Dubena Shankala, we enter Tigre, an extensive and mountainous province, bounded on the east by the river Mareb, and by the Tacazze on the west ; on its north-east corner, along the shore, it has the territory of the Bahar- nagash ; on the south and south-west it borders on Angot and Lasta. 2. From Tigre we proceed to Samen, a very mountainous region between the rivers Tacazze and Co- ror, bounded by Tigre on the north, Amhara on the south, Angot on the east, and Begemdcr and Dembea on the West. 3. Begember, a rich and valuable province, is boimded on the north by Balessan, a district adjoining to Samen ; on the east by Lasta and Angot, on the south by Amhara, fioin which it is separated by the river Bashiio, and on the west by Dembea. 4. On leaving flegcmder, we enter AnUiara, which is bounded by Begemdcr on the north, Walaka and Marrabeton the south, Angot on the east, and west by the Abay, or Abyssinian Nile. 5. Wa- laka, a low, unwholesome, but fertile province, lies be- tween the two riveis Gcshen and Samba ; and south- ward of that is the Upper Shoa. 6. Damot forms the eastern division of the country, which is incircled by the river Abay, or Bahar-cl-Azrek, which, issuing from the lake Tzana, divides this province from Begemder, Am- hara, and Shoa; it is surrounded by the same river on the south, and is separated from Gojam by the moun- tainous ridge of Litchambara. 7. Gojam, called more properly Agow-Midre, is divided from Damot by the range of Aiormasha and Litchambara ; it i-eaches on the north-west to Kuara and the countiy of the Shankala; and on the south-west and south is bounded by the Abys- sinian Nile. 8. Dembea comprehends all the country that lies around the lake of that name; including on the east Foggora, Dara, and Alata; on the north-east, Gon- dar, the metropolis, and the rich district beneath it; on the south-west, the district of Bed, or the plain barren country ; and on the west, the lands around Dingleber and Waindagar. 9. Kuara is a wild district, lying north of the lake Dembea, and bordering on Fazucio and the country of the Shankala. 10. Walkait, Tzegade, and Woggora, are low provmces north of the lake of Dem- bea. The first of these is an unwholesome district, of- ten used as a state prison. Tzegade and Woggora are excellent corn countries. Woggora, in particular, which lies east of Gondar, is one of the granaries of the king- dom. Ras-el-FecI, of which Mr Bruce was appointed governor, is a wild Mahometan district, the mostnortJier- ly territory belonging to the Abyssinians. In this list of the provinces of Abyssinia, the reader will observe that two are omitted, which Mr Bruce has included in his enumeration. These are Masuah and Sire; the former of which, situated at the entrance of Abyssinia from the Arabian Gulf, is in reality a distinct and independent territory, whose sovereign, or Naybe, originally a vassal of the Ottoman Porte, taking advan- tage of his remote situation, renounced the authoi'ity of his former lord, and chose rather to purchase the friend- ship of the Abyssinian monarch, by yielding to him one half of the annual customs of Masuah. As for Sire, it has long been absorbed in the province and government of Tigre, and seemed, therefore, to have no claim to be class- ed as a separate province. In Abyssinia, more, perhaps, than in any other coun- try, the rude magnificence of nature is strikingly display- ed. It is pervaded by vast ranges of mountains, whose amazing height, and wild irregular forms, excite at once the most sublime ideas of creative power, and the most humbling conviction of the weakness of man. Of these, some lower in the shape of pyramids, obelisks, or prisms ; some, flat, thin, and square, seem scarce firm enough to resist the violence of the wind ; while others, still more wonderful, appear like inverted pyramids, which, by some dreadful concussion, have been pitched upon tlieir points, and present an apparent exception to the general law of gravitation. To travel through these mountainous re- gions, is toilsome and hazardous. Sometimes the road is intersected by deep gullies, full of loose stones, or ob- structed by huge fragments of rock. Sometimes it lies in the bed of a torrent, which has been exhausted by the heat of summer, but which is often so suddenly swelled ABYSSIMA. 57 by the rain in ilic mountains, as to thunder down in an instant witii the violence ot a mighty river. Now it winds up the side of a steep and cragg-y hill ; and now utretches along the brink of a hanging precipiee, from which the traveller looks, with mingled delight and tear, on the deep and beautiful valley beneath. The mountains of Abyssinia appear in three ridges; the first of no great height, full of gullies and broken ground, and thinly covered with shrubs ; the second high- er and steeper, still more rugged and bare ; the third, a row of sharp uneven hills, which, though inferior to those in the centre, would yet be accounted high in any coun- tiy in Europe. Far above all the rest towers Taranta, in the east of the kingdom, whose sunnnit, generally in- volved in clouds, is never seen but in the clearest wea- ther: it is one of the highest moimtains in the world. Next to Taranta, the most remarkable are the precipit- ous mountains of Adowa in Tigre; Lamalmon,and Amda Gideon, or the Jews' Rock, in Samen ; Ganza in the south of the empire ; and the triple ridge of Aformasha, Litch- ambara, and Amid-Amid, which as they form a regular crescent, Mr Bruce supposed to be the Mountains of the Moon. Abyssinia, as might be expected in a country so moun- tainous, is watered by many streams. Besides the tor- rents formed by the rains, and the perennial rivulets which wind through the valleys, several large rivers take their rise among the hills, giving beauty and fertility to the country through which they flow. Of these the most considerable is the Bahar-el-azrek, or Blue River, called by the natives Abay ; which Mr Bruce, taking it for the Nile, traced to its sources in the district of Ras-el-Feel. For this mistake, he has been censured with a degree of petulance and acrimony, that would almost warrant the supposition, that his accusers themselves believe and envy the discovery, which they are so vehemently anxious to disprove. When Mr Bruce sailed for Africa, it was the general opinion of Europeans, that the sources of the Nile were to be sought in Abyssiuia. On his arri- val in that country, he actually found a large river which the inhabitants dignified with that name ; and it surely argued no uncommon portion of vanity or credulity, if he imagined that he had succeeded in the object of his journey, exactly where concurring circumstances led him to expect success, and exulted in the belief of hav- ing first discovered those fountains, which had so long been the subject of fruitless curiosity. The Bahar-cl- Abiad, or White River, which is the principal branch of the Nile, takes its rise among the Jibbel Kumri, or Mountains of the Moon, in the country of Donga, but its sources have not yet been explored. The river, next in consequence to the Abay, is the Tacuz, or Tacazze, which flows from three springs in the province of Angot, about 200 miles south-west of Gondar. Another branch of the Tacazze rises in tlie frontiers of Begemder, near Dabuco ; whence running between Gouliou, Lasta, and Belessan, it joins the Angot branch, and becomes the boundary between Tigre and Amhara. Tacazze was the Astaboras of the ancients, and the Abay was their Astapus. The Mareb is a large, deep, and smooth ri- ver, which forms the boimdary between Tigre and the Baharnagash. The Maleg, said to rise in the marshes of Narea, joins the Tacazze after flowing in a parallel course of considerable length. Several tributary streams, as the Angueah and Bowihah, fall into the Tacazze and Abay. The Jemma, whose sources arc in the mountains of Amid-Amid, is rather larger than the Abay, and very much more rupid. Alter flowing through the valley of St George, it crosses Maitsha, on the east of the Abay, m which it loses itself below Samsur. There are two other rivers, the Hanazo and the Ilawash, which flow in an opposite direction, towards the entrance of the Red Sea; the former of which is said to be absorbed by the sands of Adel. Some of these rivers arc distinguished by cataracts of stupendous height and volume. The most magnificent is that of the Abay at Alata. Its height Mr Bruce supposes to l)C about lorty feet. The river, wheu he viewed it, had been considerably increased by rams, and fell in one unbroken sheet of water, about half an English mile in breadth, with a force and noise that was triUy awful. A thick fmne, or haze, covered the fall' around, and hung over the stream both above and below, marking its track, though the water was unseen. The lake Tzana, or Denibca, is l)y much the largest expanse of water known in Abyssinia. It is about fifty miles long, and thirty-five in its greatest breadth, though it decreases greatly at each extremity, where it is some- times not above ten miles broad; its extent, however, differs greatly in the dry and rainy seasons. This lake is interspersed with many islaiuls, which were formerly used as prisons for the great, or as places of voluntary re- treat for the discontented or unfortunate. Near the mid- dle is one called Tzana, which is supposed to have given name to the lake. But, notwithstanding the number of rivers in Abyssinia, there are many parts of it totally des- titute of springs, or flowing streams, where the inhabi- tants are compelled to use the water of stagnant pools formed by the rains. Though situated within the torrid zone, Abyssinia is, in general, temperate and healthy. Its climate varies, indeed, with the surface and aspect of the country. In the high and mountamous regions, the coolness of the air, and the serenity of the sky, give health and sprightliness to the inhabitants ; while those confined to the valleys, or dwelling in the vicinity of marshes or sandy deserts, lan- guish under the pernicious influence of excessive heat, or a moist, stagnant suffocating atmosphere. Indeed, the climate seems to be influenced by situation and soil, al- most as much as by the latitude. On the summit of La- malmon, Mr Bruce observed the thermometer stand at 32", in the depth of winter, the wind north-west, clear and cold, attended with hoar-frost, which vanished into dew about a quarter of an hour after sunrise. He saw- hail lie for three hours on the moiuitains of Amid-Amid. But snov/ is never seen even on the loftiest mountains; nor has it found a name in the language of Abyssinia. There is a curious passage, however, in one of the na- tive historians, in which a fall of snow is very explicitly described ; but described as a phenomenon unknown be- fore, and for which no appropriate term had as yet been invented. Speaking of the village of Zinzenam, whose name signifies rain ujion rain, he thus proceeds : "This village has its name from an extraordinary circumstance that once happened in these parts. (Zinzenam lies in the level country of Foggora.) A shower of rain fell, which was not properly of the nature of rain, as it did not run upon the ground, but remained very light, having scarce the weight of feathers, of a beautiful white colour like flour: it fell in showers, and darkened the air more than rain, and liker to mist. It covered the face of the whole cotnitry for several days, retaining its whiteness the whole time ; then went away like dew, without leav- ing any smell, or unwholesome effect, behind it." The following Table, extracted from the register 38 ABYSSINIA. kept by Mr Bruce at Gondar, from February 1770 to May 1771, may serve to give some idea of" the general state of the baromcLer and thermometer during that pe- riod. We select from the register of each month the altitude most frequent at noon, and then, to show their full range, shall give the lowest and highest altitude of both, during the time when the register was kept.

On the east side towards the Red Sea, the rainy season is from October to April ; on the western, or Abyssinian side, cloudy, wet, and cold wea- ther, prevails from May to October. This may serve to reconcile an apparent disagreement in the accounts of Alvarez and Bruce. According to Alvarez, the winter in Abyssinia consists of tlirce rainy montlis, February, March, and April ; while Mr Bruce, on the contrary, assigns all these months to summer, and dates the com- mencement of winter from the close of Ajjril, or the be- ginning of May. Alvarez probably describes the sea- sons on the east of Taranta; while Mr Bruce, with more accuracy, confines his description to the seasons peculiar to Abyssinia. From the second week of September, there is an interval of dry, but sickly weather, till the 20th of October, when the rains begin again to fall, and con- tinue constant, but moderate, till the beghining of November. With the last of these rains all epidemic diseases disappear. The variety of elevation, which so much diversifies the climate of this extensive country, produces an equal- ly perceptible difTerence in its soil. Many of the loftier mountains are rude masses of rock, either totally bare, or so scantily covered with earth, as to produce nothing but stunted shrubs, or coarse bent grass. But the bar- renness of the hills is amply compensated by the rich fertility of the valleys. There, a deep and kindly soil, fostered by the rays of a vertical sun, rewards the labours of the husbandman with three harvests in the year. The first seed-time is in July and August, in the middle of the rainy season, when they sow wheat, locusso, barley, and tefl'. Towards the end of November, they begin to reap, first their barley, then their wheat, and last of all the teff. In room of these, barley is immediately sown on the same ground, without any manure, and is cut down in February. For a third crop, they sometinruis so$r tefl', but more frequently a kind of vetch, or pea, called shimbra ; these they reap before the first rains, which begui to fall in the month of April. In generaj, the level parts of Abyssinia, particularly if watered by any peren- nial stream, are, beyond description, luxuriant and beauti- ful. Nor do even the hills present an uniform aspect of sterility. Some of them, in the vicinity of the principal towns, are cultivated almost to their summits ; the sides of others are clothed with forests of stately trees,adorned at once with the richest fruit, and with flowers of exquisite beauty and delicious fragrance ; and, in passing through this mountainous country, the traveller is often surprised on gaining the height of even its wildest ridges, to meet with cheerful villages and cultivated plains. Abyssinia presents a rich field of natural history. There are, indeed, few or none of its aninials which are not to be found in other parts of Africa; but it produces many curious plants, some of which, if not peculiar to itself, have not yet been described by those who have travelled or resided in any other country. In his selec- tion of the plants of Abyssinia, Mr Bruce has chiefly at- tended to those, which, having once been regarded by the ancients as subjects of consequence, and copiously treated of in their writings, have now, through various accidents, become either of doubtful existence, or un- certain description. His attention is next directed to those which are employed in manufactures and medicine, or used as food in tlie countries where they are found. He then describes those plants, or varieties of plants, which, whether in genus or in species, are unknown. His limited knowledge of botany, however, obliged him to speak of these sparingly, and with hesitation. The plants which he has thought worthy of a particular des- cription, are the following : The papyrus, called by tlie Greeks biblos ; the balcssan, balsam, or balm ; the sassa, supposed by Mr Bruce to be the opocalpasum tree of Galen ; the ergett, or mimosa, of which Mr Bruce has described two varieties, the ergett y dimmo, and the er- gett el krone ; the ensete, a herbaceous plant, which constitutes the chief vegetable food of the Abyssinians ; the kolquall ; the rack ; the gir-gir, or geshe el Aube, a species of grass unknown to botanists till discovered by Mr Bruce ; the kantuffa ; the gaguedi; the v/ansey ; the farek,orbauhinia acuminata ; the kuara, called by botan- ists corallodendron; the walkuffa ; the wooginos, orbrucea antidysenterica, a sovereign remedy against the dysente- ry ; the cusso, or bankesia Abyssinica ; the nuk, or nuge from which the Abyssinians extract their vegetable oil j the teff", a kind of grain, from which is made the bread commonly used by the natives ; and the tocusso, a black grain which grows in the borders of the Kolla, or hot country, and of which a very black bread is ntade, eaten only by the poor. From both the teff" and tocusso bread, there is prepared a sourish liquor, called bouza, which, like our small beer, is used as the common drink of the country. Eveiy tree, and every bush in Abyssinia, not only re- tains its verdure, but bears blossoms and fruit in all sea- sons of the year. The same part of the tree, indeed, never flowers more than once in twelve months, but the process of fructification advances in a very remarkable manner through the whole. The blossoms first appear on the western boughs, and tlie fruit proceeds, through the regular stages, to maturity. The southern branches next undergo a similar process ; it then crosses the tree, and the north is in flower. The east succeeds last, ai»d ABYSSINIA. 39 produces blossoms and fruit till the commencement of the rains. All the trees are evergreen ; their loaves are highly varnished, and of a tougli leatherlike texture, which enables them to withstand the constant and vio- ient rains, under wliich they arc produced. In no country, perhaps, in the world, is there a great- er variety of animals, both wild and tame, than in Abys- sinia. Clothed in perpetual verdure, and most luxuriant herbage, it aflbrds an ample and unfailmg provision to cattle of every description. Immense rmmbers ot the COOT s/iccies every where present themselves, differing widely in size and appearance. Of these, some have no horns, and arc distinguished likewise by the colour and length of their hair,or by having bosses upon their back, according to the variety of climate or pasture. Other kinds have horns of various dimensions; and there is one species whose horns are of such a monstrous size as to be capable of containing ten quarts each. But the size of the animal bears no proportion to that of his horn ; on the contrary, he is not nearly so large as a common English cow, and the growth of horn is a disease which generally proves fatal ; as it is encouraged for a particular purpose. The terrific appearance of these animals has given rise to the fable of carnivorous bulls ; a species of monster which exists neither in Abyssinia, nor in any other part of Africa. The buffalo of this country is exceedingly ferocious; he resides not in the high and temperate regions, but in the stiltry valleys be- low, where, as if consciou's of his superior strength, he stretches himself at his ease among large spreading trees, near the clearest and deepest rivers, or stagnant pools of the purest water; yet in his person he is as dirty and slovenly, as in his disposition he is fierce and untractable. Among the wild animals are prodigious numbers of the gazcl or antclofie kind ; the boliur, sassa, Jic/io, and madoqua. These are to be met with only in the uncultivated parts of the country, where they feed chiefly on trees. They are extremely numerous in those pro- vinces, which have been depopulated by war, enjoying among the wild oats a quiet residence, without the fear of being molested by man. i/i/.e;m.s abound in Abyssinia, of which Mr Bmce supposes there are two species. Those which he had seen on mount Libanus and at Alep- po, exactly resembled the hyjena described by M. Buffon, and seemed to partake of the nature of the hog ; while those wliich infest Abyssinia are much larger, and seem more allied to the canine race. The barbarous custom of leaving the slaughtered carcasses of criminals unburi- ed in the streets, attracts the hyxnas in multitudes to the towns ; so that it is very unsafe to venture from home after it is dark. The natives believe that these animals are Falasha from the neighbouring mountains, who be- ing transformed by magic, come to bant[uet, during the night, on human flesh. Of the dog or fox khid there are few varieties. The deep, or jack-nil, is the most nu- merous class, and is in all respects the same as the deep of Barbary and Syria. The -n'tld boar is frequently seen in swamps, or on the banks of rivers covered with wood. He is smaller and smoother in the hair than those of Barbary and Europe, but differs from them in nothing else. The low hot country is inhabited by the cle/i/iant, rhinoceros, and camelo/iard ; nor do the lion, the leojiard, or the panther, ever appear in the high and cultivated regions. The country is every where infested by flocks of afies and baboons, who destroy the fields of millet; rats and inice likewise abound, and commit great devas- tation on the crops. Haret are very numerous ; and, being accounted unclean, are never Imnted but by fowls and beasts of prey. All the large rivers abound with crocodiles and /liji/to/iotami. The number of birds in Abyssinia almost exceeds belief. The high and low countries are equally stored with them. Those of the carnivorous kind occupy the rocks and mountains ; among which there are many spe- cies of the eagle, -vul/ure, and liuivk. A species of kite, called luuUnja, very frequent in Egypt, comes to Ethiopia very punctually alter the tropical rains. Their first supply of tood is aquantity of shell-fish, which have been forced by the flood from the salt springs where they have been noiu'ished ; and, when the rains subside, are left without moisture on the edges of the deserts. The car- casses of wild beasts, slain by the hunters, afford them an ample store of provisions. They next prey on field- rats and mice, that appear after harvest, and swarm in the fissures of the ground. But their chief resource is in the number of cattle slaughtered by the army on march; beasts of biu'then, which die imder carriage, or ill treatment ; or soldiers, who perish by disease or the sword, and are left to rot in the open fields. These furnish such a supply of carrion, that one would think that all the carnivorous fowls in the world were collect- ed round the camp. The fields are covered with them on every side as far as the eye can reach, and the branches of the trees are ready to break under the pressure of their weight. These supplies all fail at the commencement of th\e rains, when the hunters and armies are forced to return home, and the vast quantity of water, which inundates the coimtry, deprives them of every other kind of food. There are likewise great numbers of birds, which live upon insects. The fly, which reigns, in swarms, on the plains from May to September, is attended by a midtitude of feathered enemies, some of which devour them for food ; others seem to persecute them in re- venge for the injuries which they commit against man- kind, and the brute creation ; scattering myriads of them on tiie ground, without heeding them more. Bees, too, which abound in all parts of Abyssinia, are an unfailing supply to these birds. Nor is the granivorous tribe less numerous, or less plentifully provided with food. All the trees and shiaibs in Abyssinia bear flowers, seeds, and fruit, in every sea- son of the year ; and, as the country is divided by a ridge of mountains, which likewise divide the seasons, those birds which subsist on one particular kind of food, are transported, by a short migration, to the same seasons, and the same food, on one side of the mountains, of which a change of weather had deprived them on the other. This country has few otjIs, but those are remarkable for their size and beauty. The crovjs are black-and-white almost in equal proportions. The raven, w hich is of a large size, has black feathers intermixed with brown, his beak tipt with white, and a tuft of white feathers on his head, in the figure of a cup or chalice. j\[r Bruce saw neither sparrows, magpies, nor bats, during his residence in Abyssinia. Water fowls, too, were rare, particularly of the web-footed kind : but, during the rainy season, the plains are covered with storks of var- ious descriptions. The large birds which reside on the mountains of Samen and Taranta, are fortified against the weather by tubular feathers, the hollow part of which is full of a fine dust or powder, whi'h, on grasping them, issues out in such abundance as to i'-din the hand. There 40 ABYSSIMA. are no geese here, wild or tame, excepting what is cal- led the i^-oldcn goose, goose of Ihe Kile, or goose of the Ca/ie, which is comn^oii in every j)art of Afiica. Sniftes are found in all the deep and grassy bogs, but there are no woodcocks. There are, in Abyssinia, various kinds of swallows unknown in Eiu-ope ; those which are com- mon in Europe appear on passage, at the very season when they take their flight from that continent. Pigeons are very numerous, and all of them migrate but one kind, which lives in the eaves of houses, or holes in the wall, and which the Abyssinians account unclean, be- cause it has claw's like a falcon, of which they suppose it a mixture. There is a species of eagle, to which Mr Bruce has given the name oi\he golden eagle, which well deserves a particular description. His Ethiopic name is nisser ; and, from a tuft of hair below his beak, he is called by the vulgar .ibou Duc/i'n, or father Longbeard. He is one of the largest birds that fly. One which Mr Bruce shot measured 8 feet 4 inches from wing to wing, and from the tip of his tail to the point of his beak, upwards of 4 feet and a half. His legs appeared short but strong, and his thighs were extremely muscular. His middle rlaw was about two inches and a half long, rather strong than sharp. His bill, from the root to the point, mea- sured three inches and a quarter, and at the root was an inch and three quarters broad. From the cavity of his lower jaw proceeded a forked bunch of strong hair; his eye was remarkably small ; the crown of his head was bald, as was also the front, at the junction of the bill with the skull. His feathers, on being grasped, emitted a great quantity of yellow powder ; and those on his back produced a brov n dust of their own colour. The fea- thers of his belly and breast were of a golden colour, and seemed to have nothing extraordinary in their formation ; but the large feathers in his shoulder and wings were fine tubes, from which, upon pressijre, the powder was emitted. Besides swamis of locusts, and a species of ants, which are extremely troublesome and pernicious, Abys- sinia is likewise infested by a fly, called Tsaltsalya, an insect more formidable than the strongest or most savage wild beasts. He is very little larger than a bee, but of a thicker proportion ; his wings, which are placed se- parate like those of a fly, are of pure gauze, without colour or spot ; his head is large, his upper jaw sharp, armed at the end with a strong pointecl hair, about a quarter of an inch long ; his lower jaw has two of these pointed hairs ; and the three on both jaws, when joined together, make a resistance to the finger, nearly equal to that of a strong hog's bristle. His legs are serrated in the inside, and covered with brown hair, or down. He has no sting ; his motion is rapid and sudden, resembling that of the gad fly. The sound which he utters is a jar- ring noise, together with a humming, and seems partly to proceed from a vibration of the three hairs at his snout. As soon as the buzzing of this insect is heard, the utmost alarm and trepidation prevails. The cattle forsake their food, and run wildly about the plain, till at length they fall down worn out with terror, hunger, and fatigue. Fortunately this dreadful enemy is confined to the black loamy soil, and the sands of Atbara afford a safe retreat from his pursuit. Even the thick skin of the camel gives no security against his attacks. His body, head, and legs, penetrated by the proboscis of this fly, swell into large bosses, which break and putrefy, to his certain destruction. The elephant and rhinoceros, too, whose enormous bulk, and habits of life, prevent IhcJH from removing to dry and desert places, are obliged to roll themselves in the mire, which, when dry, cases them as it were in armour, and enables them to withstand this winged assassin. Small and inconsiderable as he appear., the Tsaltsalya seems to have given law to the first settlement in the country. He absolutely debarred the inhabitants of the rich black soil from enjoying the assistance of any beasts of labour, and deprived them of the flesh and milk of cattle for food. Another nation was thus introduced, who led a wandering life, and pre- served their herds and flocks by driving them to the sands of Atbara, till the disappearance of this insect enabled them to bring them back. Mr Bruce, in opposition to almost every account tliat has been published of Abyssinia, maintains, that there are few serpents in that country. In Upper Abyssinia he saw none of any kind, and no remarkable varieties even in the low countiy, excepting the large snake call- ed boa, which is often above twenty feet in length, and as thick as an ordinary man's thigh. His chief residence is by the grassy stagnant pools of rivers. He is an ani- mal of prey, and feeds upon antelopes and deer, which, as he has no canine teeth, he swallows in whole pieces, after having broken the bones, and drawn them out into a length to be more easily managed. There is likewise a species of horned viper called cerastes, which is gene- rally about 13 or 14 inches long. It has sixteen small immoveable teeth, and in the upper jaw two canine teeth, hollow, crooked, and finely polished. Its poison, con- sidering its size, is very copious, and is contained in a bag under its canine teeth ; when these are taken out, an operation very easily performed, the viper bites without any fatal consequence. Its horns are about three-twelfths of an inch long, and its body, where thickest, about ten- twelfths. It moves with great rapidity, and in all direc- tions. When inclined to surprise any person who is too far from it, it creeps with its side towards him, and its head averted, till, judging its distance, it turns round, and springs on him. Mr Bruce vouches, from his own observation, for the reality of the incantation of serpents. At Cairo he saw a man take a cerastes, with his naked hand, from a num- ber of others at the bottom of a tub, put it in his breast, twist* it about his neck, and last of all eat it with as little repugnance as if it had been a stock of celery. All the black people of Sennaar are perfectly armed against the biteof either scorpion or viper. They take them with- out scruple in their hands, and toss them to one another like balls, without irritating them so much as to bite. The creature, however lively before, when seized by one of these barbarians, always appeared languid and feeble, frequently shut his eyes, and never turned his mouth towards the arm of the person that held him ; yet, when a chicken was made to flutter before him, his seeming indifference left him ; he bit it with great signs of rage, and the chicken died almost instantly. These people pretend to possess a natural exemption from the noxious power of serpents ; and, by certain medicines, can com- municate this exemption to others. The Arabs acquire it from their infancy, by chewing a certain root, and washing themselves with an infusion of certain plants in water. Though the drugs were given to Mr Bruce, and he several times fortified himself for the experiment} his resolution always failed him at the moment of trial. So much for the natural history of Abyssinia, which we have detailed tJie more minutely, because the facts ABYSSINIA. 41 which it prcsejUs, vhilc they are not uninteresting to the general reader, are cah-,ulated to give the naturalist the most correct idea of tlie peculiarities of climate and country. If the external features of this extensive resjion are singular and striking — the character and manners of its inhabitants are still more so. The picture is indeed mortifying and disgusting ; for of all the people in the world, the Abyssinians are ])erliaps the most barbarous and depraved. The thirst of revenge, inflamed by per- petual hostilities, and by personal and national injuries, has frequently impelled the savage to torture and devour the body of his captive enemy. We sicken with horror at the recital, and cannot easily be reconciled to the idea, that we partake of the same nature witli the mon- strous cannibal. But what shall we think of a people, who, without the irritation of war, or the animosity of revenge, seem habitually to delight in cruelties scarce less enormous, and whose daily banquets arc disgraced by the protracted torture of the vmhappy animal, which is destined to be the victim of their unnatural luxury ? Mr Bruce, who was frequently compelled to be pre- sent at these horrid festivals, has given a very lively description of one of them, which we shall transcribe in his own words. " A long table is set in the middle of a large room, and benches beside it for a number of guests who are invited. A cow or bull, one or more, as the comp?.ny is numerous, is brought close to the door, and his feet strongly tied. The skin that hangs down under his chin and throat, which I think wc call the dewlap in England, is cut only so deep as to arrive at the fat, of which it totally consists, and by the separation of a few small blood vessels, six or seven drops of blood only fall to the ground. They have no stone, bench, nor altar, upon which these cruel assassins lay the animal's liead in this operation. I should beg his pardon indeed i'or calling him an assassin, as he is not so merciful as to aim at the life, but on the contrary, to keep the beast alive till he be totally eaten up. Having satisfied the IVIosaical law, according to his conception, by pouring these six or seven drops upon the ground, two or more of them fall to work ; on the back of the beast, and on each side of the spine, they cut skin deep ; then putting their fingers between the flesh and the skin, they begin to strip the hide of the animal half way down his ribs, and so on to the buttock, cutting the skin wherever it hinders them commodiously to strip the poor animal bare. All the flesh on the buttocks is cut off then, and in solid square pieces without bones, or much effusion of blood ; and the prodigious noise the animal makes, is a signal for the company to sit down to table. " There are then laid before every guest, instead of plates, round cakes, if I may so call them, about twice as big as a pancake, and something thicker and tougher. It is unleavened bread, of a sourish taste, far from be- ing disagreeable, and very easily digested, ma(Je of a grain called teff. It is of different colours, from black to the colour of the whitest wheat-bread. Three or four of these cakes are generally put uppermost, for the food of the person opposite to whose seat they are pla- ced. Beneath these are four or five of ordinary bread, and of a blackish kind. These serve the master to wipe his fingers upon, and afterwards the servant, for bread to his dinner. Two or three servants then come, each with a square piece of beef in his bare hands, laying it upon the cakes of teff, placed like dishes down the table, without cloth or any thing else beneath them. Bv this Vol. I. Part I. time all the guests have kniics m their hands, and their men have the large crooked ones, which they put to all sorts of uses during the lime of war. The women have small clasped knives, such as the worst of the kind made at Birmingham, sold for a penny each. The company arc so ranged, that one man sits between two women ; the man, with his long knife, cuts a thin piece, which would be thouglit a good bcaf-steak in England, while you see the motion of the fibres yet perfectly distinct, and alive in the flesh. " No man in Abyssinia, of any fashion whatever, feeds himself, or touches his own moat. The women take the steak, and cut it lengthways, like strings, about the thickness of your little finger, then crossways into square pieces, something smaller than dice. This they lay upon a piece of the teft" bread, strongly powdered with black or Cayenne pepper, and fossil salt ; they then wrap it up in the tefl' bread like a cartridge. In the meantime, the man, having put up his knife, with each hand resting on his neighbour's knee, his body stooping, his head low and forward, and his mouth open, very like an idiot, turns to her whose cartridge is first ready, who stuffs the whole of it into his mouth, which is so full, that he is in constant danger of being choked. This is a mark of grandeur. The greater a man would seem to be, the larger piece he takes in his mouth ; and the more noise he makes in chewing it, the more polite he is thought to be. They have, indeed, a proverb, that says, " Beggars and thieves only cat small pieces, or without making a noise." Having despatched this morsel, which he does very expeditiously, his next female neighbour holds forth another cartridge, which goes the same way, and so on till he is satisfied. He never drinks till he has finished eating ; and before he begins, in gratitude to the fair ones that fed him, he makes up two small rolls of the same kind and form ; each of his neighbours open their mouths at the same time, while, with each hand, he puts their portion into their mouths. He then falls to drink- ing, out of a large handsome horn ; the ladies eat till they are satisfied, and then all drink together. A great deal of mirth and joke goes rovmd, very seldom with any mixture of acrimony or ill humour. " All this time the unfortunate victim at the door is bleeding indeed, but bleeding little. As long as they can cut off the flesh from his bones, they do not meddle with the thighs or the parts where the great arteries arc. At last they fall upon the thighs likewise ; and soon after, the animal, bleeding to death, becomes so tough, that the cannibals who have the rest of it to eat, find very hard work to separate the flesh from the bones with their teeth like dogs." This inhuman joractice is so repugnant to the manners and sentiments of Europeans, that some have been in- duced to regard it as altogether absurd and impossible. But, not to mention the temerity and the injustice of rejecting an account of distant nations, because it hap- pens not to coincide with our own customs, or precon- ceived opinions, — Mr Bruce's narrative is confinned by the testimony of other travellers, and, in a certam de- gree, by the practice of other countries. Lobo assures us, that the Galla eat raw meat, and notliing else, a cus- tom which seems to have prevailed pretty generally in the south of Africa. Speaking of the Abyssinians, he aflirms, "that their greatest treat is a piece of i-aw beef, Qtiite warm. When they give a feast, they kill an ox, and immediately serve up a quarter of it on the table, with much pepper and salt ; and the gall of the ox serves 42 ABYSSINIA. them for oil und vinegar." To cuttlic atiimal in pieces while alive, is an easy and natural refinement on tliis liarbarous practice ; and accordingly Abram, an Abys- sinian, told sir William Jones, that the coimtry people and soldiery made no scruple of drinking the blood, and eating the raw llesh of an ox, not caring whether they cut it when dead or alive. A people of such unexampled cruelty towards brute animals, cannot be expected to pay much regard to the sufierings of their fellow creatures. InureU from then- infancy to blood, murder seems almost their pastime. Even children, when provoked, are prevented only by tlie want of strength from imbruing their impotent iiands in the blood of a playfellow, or a brother. Their sanguinary laws are but a weak restraint against these violent pas- sions, when seconded by greater strength and address ; and the punishments annexed to the laws themselves, exhibit the most striking example of the national cru- elty. One of these punishments is flaying alive ; and even Ozoro Esther, the heroine of Mr Bruce's narra- tive, smiled with savage complacency when presented witli the skin of an enemy. Criminals arc frequently hewn in pieces with a sabre ; nor is this performed by common executioners, whose office, in evei-y civilized countiy, is held infamous and detestable, but by people of quality, and officers of rank. So little, indeed, is thought of these executions, that Mr Bruce, happening one day to pass by an officer who had three men to despatch in this manner, was coolly requested by him to stop till he had cut Uiem all to pieces, as he wished to converse with him upon an affair of consequence. Stoning to death is another capital punishment frequent in Abys- sinia; inflicted generally on Franks and Roman Catho- lics, when they happen to be found, and on other here- tics in religion. To say that these savages are perfidious and false in the extreme, is only to delineate a natural feature of their hideous character ; for, where the laws of huma- nity are habitually outraged, the restraints of morality, or of houotir, will be unknown or disregarded. So completely is the moral sense of the Abyssinians per- vei-tcd, that they prefer deceit to honesty, and falsehood to truth, when their interest seems in noways concerned in the preference. Even those regulations, which seem essential to the very existence of society, are but little respected by those rude barbarians. Marriage is here a very slender tie, formed and dissolved at pleasure ; and chastity is a virtue which they hold in very low esteem. Their marriages are celebrated in the church, to be sure, with great solemnity, and the parties bind them- selves, by an oath, to continue faithful to each other for life. They make no scruple, however, of breaking these engagements, whenever they find it inconvenient or unpleasant to live longer together ; and their divorces and marriages are accordingly vei-y frequent. Mr Bruce tells us, that he was once at Koscam, in presence of the Itcghe (or queen-dowager), when in the circle there was a woman of great quality, and seven men, who had all been her husbands, though none of them was then the happy spouse. If the husband first wishes to be released from his engagement, he, or his surety, must restore the portion which the lady brought him, ind pay her likewise the sum stipulated in case of se- paration. If it be the lady who desires to recover Ircr liberty, the husband is liable to no restitut.on, provided he has been faithful, according to a contract, hi the dis- cliargc of his conjugal duties. Sometimes, without any quarrel or ill-will, a separation is agreed on by mutual consent. In this case, the portion of the wife is united with the sum stipulated by the husband, of which Incy receive each an equal share. If they liave any progeny, the boys always go with the mother, even though there be only une child ; if there be no sons, she claims none of the girls. Among the lower ranks, marriages are contracted with less ceremony, and are still more easily dissolved ; but the king's judges, or governors of pro- vinces, take care, that the children shall be maintained either by their parents, or by some other person. Where the nuptial umon is held so little sacred, jealousy cannot be supposed to prevail ; and the distinction of legitimate and illegitimate offspring is unknown. Such is a faint outline of the Abyssinian character ; and, hideous and disgusting as it is, it is the character of a people professing Christianity, who have the scrip- tures translated into their own language, and whose countiy is filled with churches innumerable ! But let not the infidel triumph in the concession. The Chris- tianity of the Abyssinians is a mere systein of parade, extending little further than the acknowledgment of saints, and the observance of festivals ; nor can it be wondered, if the pure and humanizing morality of the gospel has produced little improvement on the charac- ter of a people, who place the essentials of religion in external pageantiy, and think the most flagrant crimes sufficiently expiated by the erection of a sanctuary, or the utterance of a prayer. Yet the brut il manners of the Abyssinians might certainly be laid to the charge of Christianity with as much justice, as those enormities, which, during the dark ages, were perpetrated in its name, and which the candour of modem philosophers has endeavoured to construe into objections against the benign tendency of the Christian religion. A more probable cause of their barbarity might be foulid in the degrading influence of their government. It is an anomalous kind of monarchy : the will of the sovereign is the only law; his power over the lives and property of his subjects is uncontrolled ; but, at the same time, is unsupported by such a militaiy force as is necessary to give effect and consistency to its opera- tions. The militia of the several districts is entirely at the disposal of their respective governors, whose gene- ral safety depends on the weakness and necessities of the prince. Any of these governors is more than a match for his sovereign : indeed, the government of Tigre alone is equal to all the rest of the empire. Though the sovereignty be so far hereditaiy, that it is confined to one family, in that family it is elective : and as the ruling minister, in the name of the people, deter- mines the election, it generally falls on an infant, during whose minority the minister continues to exercise all the prerogatives of the crown. Hence rebellions and civil wars perpetually agitate this disjointed government ; and the citizens, engaged in unceasing hostilities with each other, contract, of course, that savage ferocitv', by which they are so infamously distinguished.* While the right of succession to the throne was tliti'S undefined, • Tlip devnstalions committed by the Abyssinian armies are dreadful beyond description. " An army," says Mr Bruce, " leaves no- tliing living behind, not even the vestige of s, habitation ; but iirc and the sword redaee every thing to r wilderness and solitude. The ABYSSINIA. 43 the elected monaicli woukl necessarily incur the hatred and resentment of the other branches of llie royal fLUiiily. To prevent the feuds which would result from their mutual animosity, the Abyssinians had recourse to the expedient of confining the prhices of the lilood to a kind of state prison, situated on some lofty and solitary moun- tain, wlicrc they were educated in a total ignorance of political transactions ; and, when the throne happened to be vacant, the nobles, or rather the prime minister, se- lected from these captives the person, who appeared best qualified, by his simplicity or pliability, for being their future king. The weakness of the royal family, and the preponderating power of the governors, have rendered these precautions unnecessary, but the practice has not yet been abandoned. In the better days of this kingdom, the royal office was intrenched with all that splendour and ceremony by which despotical governments are distinguished ; and which, by keeping the subject at an awful distance, ex- cite for the person of his sovereign a degree of venera- tion approaching to worship. The monarch was invested in a manner at once solemn and romantic. Dressed in crimson damask, with a chain of gold about his neck, and his head uncovered, he mounted a horse, richly capari- soned, and advanced, at the head of his nobility, to the paved area before the church. A number of young girls, daughters of the Ambares, or supreme judges, with many other noble virgins, ranged themselves on each side of the court. Two of the noblest held in their hands a cord of crimson silk, stretched across from row to row, and drawn tight about breast high. The king then en- tered at a moderate pace, displaying his skill in horse- manship as he went along. When he advanced to the cord, the damsels cried out, "Who are you!" He an- swered, " I am your king, the king of Ethiopia." " You shall not pass," they replied, "You are not our king." Retiring a few paces, he again presented himself, and the question was repeated as before. "lam your king," was his second reply, " the king of Israel." But this answer likewise was rejected. Returning a third time, and being asked again, " Who are you ?" " 1 am your king," he exclaimed, " the king of Sion," and, unsheath- ing his sabre, cut asunder the cord. The virgins chaunted hallelviiahs, and the air nmg with the accla- mations of the anny and the royal attendants. Amidst these expressions of joy, he rode up to the stair of the church, and there dismounting, sat down upon a stone, resembling an altar of Anubis, or the Dog-star. A num- ber of priests followed in procession. The king was first anointed, and then crowned. Singing priests at- tended him half-way up the steps; he then stopped a.t an aperture, made on purpose in the stair, where he was fumigated with myrrh, aloes, and cassia. Divine ser- vice was celebrated, and, on his return to the camp, fourteen days were spent in feasting and rejoicing. See Psalm xxiii, "! — 10. Their coronations are nowconducted with less magni- ficence ; and many of their ancient ceremonies have fallen into disuse. Enough still remain, however, to give splendour and dignity to the government ; and a striking resemblance may be traced between many of the customs which still prevail in Abyssinia, and the pompous usages of the Persian court. The king of Abyssinia, like the Persian monarchs of old, is saluted with the title of " King of kings." Subjects, in botli countries, approach the royal person, with the external signs of adoration, prostrating themselves before him, and continuing in that postuie till ordered to rise. As nothing preserves, or heightens the veneration for ma- jesty so much as distance and reserve, neither the Abys- sinian nor Persian monarch ever exposes himself to the view of his subjects. When the king of Abyssinia either rides abroad, or gives audience in his palace, his head and forehead are perfectly covered ; and one of his hands is placed on his mouth, so that only his eyes are seen. This total seclusion from the public, though m one re- spect advantageous, was attended with many inconve- niencies ; to remedy which, two officers were appointed in Persia, who were called the King's-Eyes and the King's-Ear, and who were intrusted with the dangerous charge of seeing and hearing for their sovereign. The Abyssinian monarch holds communication with his sub- jects by means of an officer named Kal-Hatze, the voice, or word of the king. When sitting in council, or in judgment, he is enclosed in a kind of balcony, with lattice windows and curtains before him. In cases of treason, he speaks through a hole in the side of his bal- cony to the Kal-Hatze, who conveys his questions or remarks to the judges, who are seated at the council- table. When consulting on civil affairs, the counsellors are seated at the table : and the king, though himself unseen, has a distinct view of them all. They deliver their sentiments, according to their age or rank ; the youngest, or lowest officer, always speaking first. After they have concluded their dclilicrations, the whole as- sembly rise, and the Kal-Hatze pronounces the royal decree. Though the original object of these delibera- tions must have been to decide on any measure accord- ing to the sense of the majority, yet no majority can pre- vail against the prerogative of the king : nay, even a majority have frequently been punished by imprison- ment, when their sentiments happened to differ from those of his majesty. In Abyssinia, however, the an- cient custom of the monarch's concealing himself from public view, is now less strictly observed. The constant wars in which this country has been engaged, since Adel was occupied by the Mahometans, have often compelled the sovereign to expose his person in the field ; and on many occasions, the army, and the kingdom at large, have been indebted for safety and victory to the skill and gallantry of their prince. In the time of war, he is at- tended by an officer, named Lika Magwass, who rides constantly round him, carrying his shield and his lance ; and such was the respect once paid to him, not only by foreign enemies, but even by his own subjects in rebel- lion, that, before the arrival of the Europeans, no king of Abyssinia ever fell in battle. At that period, the practice, both of excommunicating and murdering their sovereigns, seems to have been first introduced. Even yet, however, the respect for the royal person is, in some degree, retained ; and, in the day of battle, he is often arrayed in his insignia, lest, being unknown, he should perish by the sword of his enemies. Those who wish to complain of grievances, assemble, beasts and bh'ds unmolested have the country to themselves, and increase beyond all possible conception." The number of unburied carcasses would be sufficient to occasion contagious distemper-s, did not these voracious animals consume them before putrefaction. The carrion fowls, which follow an armj while in motion, form a black canopy, extending over it for leagues. When it encamps, the ground and trees are covered with them beyond die reach of sight. F 2 -14 ABYSSINIA. at break of day, bcTorc Uie doors ;iiid windows of the palace, and continue tlicrc till night, crying for justice in aloud and querulous tone, and in all the difl'crtnt lan- guages which they can speak. It may well be supposed, that in a country so ill governed as Abyssinia, involved too in perpetual wars, there will be multitudes of suffer- ers, who have to complain of real injuries ai.d violence. What was at first only an unhappy consequence of a bad government, has now grown into an established form ; insomuch, that when the rains prevent the really dis- tressed from approaching the capital, or standijig in the streets, a set of vagrants are provided and maintained, whose business it is to imitate the various tones of sor- row and of pain ; and this, they say, is for the king's honour, that he may not be lonely from the quietness of the palace. The burden of these complaints, whether real or feigned, is always, Rcte O jan hai ; Do me jus- tice, O my king. When quickly repeated, it very much resembles Prete Janni, (of which Prisier John is a cor- ruption,) tlie name that was given to this prince, and the derivation of which has not yet been ascertained. As if the clamour of these complainants were insuf- ficient to rouse his majesty from his morning slumbers, he has an officer, called Serach IVIassery, who, with a long wfiip, begins cracking and making a noise at the door of the palace before the dawn of day. This fright- ens away tlie hyaena and other wild beasts, and serves likewise as a signal for the king to arise ; for he sits in judgment every morning till eight o'clock, his hour of breakfast. He has likewise six noblemen of his own election, who are called Baalomaal, (masters of his effects,) and whose ofRce corresponds to tliat of gentle- men of the bed-chamber ; four of these always attend him. There is a seventh, who is their president, called AzelefTa el Camisha, groom of the robe or stole. He is keeper of tlie king's wardrobe, and first officer of the bed-chamber. These officers, with the black slaves, and some others, wait upon the king as menial servants ; and enjoy a degree of familiarity with him, to which no otlier subject is admitted. There are many other officers in the king's retinue ; but to enumerate them, would only incumber our pages with uncouth and^barbarous names, without conveying any precise idea of the offices which they denote. The Kasmati of Tigre is the most power- ful of the governors ; and the office of Ras is the highest dignity to which a subject can attain. As the use of money is unknown in Abyssinia, the revenue is paid in bullion gold, and the rude products of the various provinces. Agowmidre pays the king annually about 1000 ounces of gold, 1000 dabras of ho- ney, and 1000 or 1500 cattle ; Damot pays 800 ounces of gold; Gojam 80 ounces, and 70 mules; Lasta 1000 ounces ; Tigve pays to the amount of 400 ounces in salt and cotton cloths; Walkait 1300 ounces in cotton doth. The want of money is supplied by fossil salt, which, being divided into square pieces about a foot long, is the only medium of traffic used in this country. The value of commodities is sometimes estimated likewise by cot- ton cloths ; thus they say, that an article is worth so many webs or cloths of cotton. Various coins, indeed, are current at Masuah, which, being the very entrance of Abyssinia, is a place of considerable trade. These coins have been introduced by the commercial inter- course of this island with the opposite coast of Arabia. Their names, and relative value, may be learned from the following tabic : Venetian sequin Pataka, or imperial dollar 1 harf 10 kibccr 1 kibeer \ ' 4 patuka. 28 harf. 4 diwani. 1 diwani. 3 borjooke, or graine. The borjooke are small glass beads of all kinds and • colour, which, whether broken or entire, pass lor small money ; the harf is equal to 120 grains of these beads. The wakea, or Abyssinian ounce, is equivalent to 10 derims or drams, and 12 ounces make a litir, or rotol, which may therefore be called the Abyssinian pound. At Gondar, the capital, a wakea is equal to 6 drams 40 grains Troy weight, and is divided into 10 di'ams of 40 grains each. The ordinary value of a wakea is from 72 to 76 of the salt bricks already mentioned. In 1769 the wakea was sold at 80 salts, and in 1770 at 34; but the bricks diflfered considerably in size. The grain measure used in Abyssinia is the ardeb, which contains 10 measures called madega, each equal to 12 ounces Cairo weight. An ardeb of grain costs 2 derims or 2 patakas ; an ardeb of teff" the same ; 6 or 8 ardeb of tocusso are equivalent to an ounce, or 10 derims, of gold. Comparing the natural advantages of this country with the ancient date of its empire, we might reasona- bly expect to find it possessed of extensive commerce, and of all those arts and manufactures which commerce leads in its train. Yet such has been the paralyzing in- fluence of its government, that its commerce is limited by the shores of the Arabian Gulf, its manufactures are contemptible, and the useful and elegant arts are here almost totally unknown. The use of the plant merjom- bey, a species of solanum, and of the juice of the kol- quall tree, enables them to tan hides in great perfection. Coarse cotton cloth is the staple manufacture of the country ; but so completely are they ignorant of the art of dyeing, though possessed of all the necessary mate- rials, that yellow, produced from the plant suf, is the only colour which they have. To procure a blue border for their cotton cloths, they unravel the threads of the blue cloth of Surat, and then weave them again into their own webs. Their earthen ware is tolerable ; but though Cosmo de Medici, among other artisans, sent manufac- turers of glass to the king, ther were unable to impart to the rude inhabitants the knowledge of these valuable arts. Nor has their progress in architecture been at jdl more considerable. Their houses are very mean, constructed chiefly of clay, and thatched in the form of cones. The salubrity of elevated situations, and the inconveniences attending the inundation of the rivers during the rains, have induced them to build many of their towns and vil- lages on tlie mountains. The houses are separated by hedges of unfading verdure, which, being intermixed at regular intervals witli fruit-trees and flowers, at once give beauty to the scene, and salubrity to the air. Gondar, the present metropolis, stands on the summit of a mountain of considerable height. In times of peace, it contains about ten thousand families ; and, as the houses consist of only one story, it must occupy a prodi- gious extent of ground. At the west end of the town stands the royal palace, formerly a structure of consi- derable consequence. It was a square building, four Stories high, flanked with square towers, and commanded ABYSSINIA. 45 ifonithe top a magnificent view of all the country south- ward to the lake of Tzana. It was built by masons Irom India, in the reign of Facilidas, about the middle of the seventeenth century ; and by sueh Abyssinians as had been instructed in architecture by the Jesuits, without adopting their creed, and continued in the country after the expulsion of the Portuguese. Great part of it is now in ruins, having at different times been burnt ; and suc- cessive princes have added to it apartments built of clay, after the fashion of the country. The palace, and all the buildings connected with it, are surrounded by a substantial stone wall, about thirty feet high, the four sides of which are about an English mile and a half in length. Kosco.m, the palace of the Iteghe, is situated on the south side of the Debra Tzai, or Mountain of the Sun. It consists of a square tower of three stories, with a flat parapet roof or terrace, and battlements around it. It is encompassed by a high outer wall, above a mile in circumference. Within tliis enclosure, there is a church built, says Mr Bruce, by the present Iteghe, and account- ed the richest in Abyssmia. The large crosses carried in procession are of gold, and their kettle drums of silver. Plates of gold, likewise, cover the altar, all the gifts of the munificent patroness. Behind the palace, and farther up the hill, arc the houses of people of quality, chiefly relations of the Iteghe herself. Axitm, once the capital of Abyssinia, is distinguished by extensive ruins. In one square, apparently the cen- tre of the town, there are forty obelisks of granite ; none of which, however, have any hieroglyphics. Of those which are still standing, there is one larger than the rest; but two have fallen which appear the largest of all. On the top of that which is standing, there is a pa- tera, in the Grecian taste, exceedingly well carved ; be- low, there is the figvu'e of a door-bolt and lock, as if to represent an entrance through the obelisk into some building behind. Upon the face of the obelisk, there is a great deal of carving in a Gothic taste, like metopes, triglyphs, and guttae, disposed rudely, and without or- der. Towards the south, there is a road cut in a moun- tain of red marble, having on the left a parapet wall, about five feet high, solid, and of the same materials. In this wall, there are hewn, at equal distances, solid pedestals, which still retain the marks of the colossal statues of Syrius, the Latrator Anubis, or Dog-star. One hundred and thirty-three of these pedestals are still in their places ; but only two figures of the Dog remain, much mutilated, and in a taste plainly Egyptian. Of a superb temple, which once graced this capital, the only remains are two magnificent flights of steps, com- posed of granite, several hundred feet long, and still in their original position. Below these steps, there are three small square enclosures, in the middle of one of ■which is the stt)ne, upon which the king sits when he is crowned ; and below it, where he naturally places his feet, there is a large oblong slab of freestone, bearing an inscription, which, though much defaced, Mr Bruce has ventured to restore. It is HTOAEMAIOY EYEPTETOT BASIAEnS. The foundation, rise, and desertion of this city, is one of the obscurest parts of Abyssinian history. Its ruins, however, sufficiently prove it to have been the work of Egyptian artists, and it was probably founded by one of the Ptolemies, There are few other towns in Abyssinia, nor arc these of any importance. The only buildings cf consequence, which ii contains, arc the works of fo- reigners ; nor have these specimens of architecture in any degree improved the tasle or skill of the inha- bitants. The Abyssinians, like the ancient Egyptians, compute time by the solar year. Their month consists of 50 clays, and, to complete the year, they add five days and a quar- ter to the month of August, which they call Nahasse. Every fourth year they add a sixth day. With them, as with all the Eastern nations, the year begins on the 29th or 30th day of August, that being the first of their month Mascaram. It is uncertain whence the names of their months have been derived: they have no signifi- cation in any of the languages of the country. Their common epoch is from the creation of the world, which they date 5500 years before the birth of Christ, reject- ing the calculation of the Greeks, who make that period consist of 5308 years. They make use, likewise, of many other epochs, such as from the covmcils of Nice and Ephcsus. In all their ecclesiastical computations, they invariably employ the golden number and epact. The use of the epact, according to Scaliger, was first adopted by the Abyssinians in the time of Dioclesian. But this opinion is at variance with the positive evi- dence of Abyssinian history, which ascribes the inven- tion of the epact to Demetrius, patriarch of Alexandria, who was elected in the reign of the emperor Severus, long before the time of Dioclesian. The Abyssinians have another method of computing time peculiar to themselves. They describe their years by the names of the four Evangelists, and will tell you, that an event happened in the days of Matthew, Mark, Luke, or John. They mark out the different periods of the day in a very arbitrary and irregular manner. The first period, called Nagge comprehends the short and scarcely perceptible morning twilight. Mesct, the evening twilight, denotes the instant between the sun's decline and the appearing of the stars. Mid-day is called Kater, a very ancient word, which signifies culmination ; and any other part of the day is expressed by pointing at that place in the heavens where the sun was at the time of which they speak. The natives arc, in general, of a dark olive complexion, and, from a just antipathy against the sanguinary and fanatical Jesuits, they detest the resemblance of a white complexion ; insomuch that they even show aversion to white grapes. The principal part of their dress is a large cotton cloth, with a blue and yellow border, which they wrap round them in a particular manner, and bind with a sash. Besides these robes, which are light and beautiful, they wear a kind of breeches reaching to the middle of their thigh, and girt with a belt of white cloth; those of the higher ranks are made of red Indian cotton cloth, with girdles of silk or wo'"stcd brought from the Levant. Their head-dress is a kind of turban. On this subject, Mr Bruce has given a curious disser- tation, intended to prove, that the Ethiopian language was the original language of mankind ; and that its al- phabet was composed of the first written characters that had ever been invented. But his theory, though ingenious, will not stand the test of sober investigation. The language of Abyssinia is an ancient offspring of the Arabic ; for it will appear in the sequel, that Ethiopia was peopled by a colony from the Arabian peninsula. It is divided into various dialects, the principal of which arc the Tigvin. or that of Tigrc, and the Amharic, which 46 ABYSSINIA. is now the prcvailinc; language of this empire. With regard to the characters, we arc inlornied by Mr Mur- ray, the ingenious editor of Brute's Travels, that "they arc nothing else but the Coptic forms of the Greek al- phabet, modelled on the plan of tlie Arabic, deranged from their former order, and made rude by the hands of barbarous scribes. The change made in the Arabic alphabet by Ibn Mocla, is well known ; but it expresses none of the vowels. Long before that time, the mis- sionaries, who first wrote the Geez, took the Greek al- phabet from Egypt ; but finding that the language was more related to the Arabic and Hebrew than the Greek, they still retained such of those letters as were common, with which they expressed the Geez words in the Ara- bic or Hebrew manner." The Abyssinian language has been illustrated bylhe labours of Ludolf, and other mis- sionaries; it is probably nearly allied to the Coptic or Egyptian, as a great intercourse once subsisted between the two countries. Having thus detailed, at some length, the manners, institutions, and present condition of Abyssinia, we shall now proceed to give a sketch of its history, which the limits prescribed to us for articles of this nature will necessarily render short and imperfect. Various opinions have been entertained concerning the original population of Ethiopia. It was known among the Jews by the name of Cituli ; an appellation which applied likewise to the peninsula of Arabia, as well as to the country watered by the Araxes ; and to the region adjacent to Egypt, on the coast of the Ara- bian gulf. To all these countries, the name was evi- dently transmitted from Cush, the grandson of Noah ; but the honour of being his lineal descendants has been chiefly disputed by the Arabs and Abyssinians. The majority of the learned have decided in favour of the Arabs ; maintaining that Cush having settled in Ai'abia, his descendants gradually migrated to its south-eastern extremity ; whence, by an easy passage, they transport- ed themselves across the straits of Babelmandeb, and entered the countxy properly called Ethiopia. Accord- ing to some writers, this migration took place while the Israelites resided in Egypt; others date it from the pe- riod when they were governed by judges in the land of Canaan. On the other hand, a tradition prevails among the Abyssinians, which, they say, has been transmitted from time immemorial, that, soon after the flood, Cush, with his family, passed through Atbara, at that time un- inhabited, till they came to the ridge of mountains, by which that country is separated from the high lands of Abyssinia. Still dismayed by the remembrance of the deluge, of which the tropical rains would seem to threat- en a return, they did not venture to settle in the plains of Atbara, but chose to dwell in caves scooped out in the sides of the mountains. The tradition seems to be partly refuted by the art which is displayed in the forma- tion of these subterraneous abodes. " It is an undoubt- ed fact," says Mr Bruce, "that here the Cushites, with unparalleled industry, and with instruments utterly un- known to us, formed for themselves commodious, yet wonderful habitations, in the heart of mountains of gra- nite and marble, which remain entire in great numbers to this day, and promise to do so till the consummation of all things." Now, it is not easy to conceive, how the first inhabitants of a world, recently emerged froin the waters of the flood, could possess cither knowledge or means suflicient for working the heart of marble or gra- nite, " into commodious, yet wonderful habitations." Such works could only be accomplished by men \vh« had long been united in regular society, and among whom art, and even science, had been cultivated with assiduity and success. These reflectioos give additional probability to the conjecture, that Ethiopia was peopled by a colony of Cushites from Arabia; the resemblance, wiiich may still be traced between the features of the Arabs and Abyssinians, sufficiently indicates their af- finity. As the Cushites became more numerous, they occu- pied all the neighbouring mountains, still retaining their original custom of dwelling in caverns, till extending from one range to another, they spread their arts and industry quite across the continent of Africa, from the eastern to the western ocean. Early in the days of Abraham, if we may believe the Abyssinian traditions, they founded the city of Axum, whose ruins still bear testimony to its ancient magnificence. Soon after, they penetrated into Atbara, where, pleased to find themselves beyond the limits of the tropical rains, which impeded their progress in astronomy, their favourite science, they built the city of Meroe, afterwards celebrated as capital of that extensive peninsula of the same name, which is formed by the branching of the Nile. Yet it does not appear, that, even after building these cities, they relinquished their ancient habitations in the moim- tains. Mr Bruce saw many of these caves immediately above the site of Meroe ; and, as a number of similar excavations are to be seen near the top of a mountain in the neighbourhood of Thebes, that city likewise probably owed its origin to a colony of Cushites. While the northern and central parts of their territory were the scenes of such improvement, the colony had extended itself southward along the mountains that run parallel to the Arabian gulf. In that rich tract of coun- try, then more important and better known than any part of the globe, they found all the perfumes and aromatics of the East, cassia, frankincense, and myrrh. It was called Saba, or Azabo, signifying south, because it lay on the southern coast of the Red Sea. Penetrating still farther in the same direction, they entered into a de- lightfid climate, where, in the course of their excava- tions, they discovered large quantities of gold and silver, lying in globules, pure and unalloyed, without any ne- cessity of being prepared or separated. These local advantages naturally directed their atten- tion to commerce ; and the Ethiopians seem to have been, at that early period, a nation of the first import- ance for opulence and civilization. In the district ex- tending from Meroe to Thebes, cities were built which displayed many improvements in architecture ; com- merce and agriculture iiitroduced the elegant arts ; and the science of astronomy was cultivated with ardour, and with peculiar advantage, under the unclouded sky of the Thebaid. Nor were the sciences neglected by their countrymen in the south. Those who dwelt within the limits of the tropical rains, confined to their caves or houses for six months in the year, would naturally be led to employ their time in sedentary occupations. " Let- ters," says Mr Bruce, " at least one kind of them, and arithmetical characters, were invented by this middle part of the Cushites; while trade and astronomy, the natural history of the winds and seasons, were what ne- cessarily employed that part of the colony established at Sofala, most to the southward." The nature of the commerce in which the Ethiopians were engaged, the collecting of gold, and preparing of ABYSSINIA. 47 Sipices necessarily confined them to their own country ; and, Uiat ihcy might reap the full advantage of these valuable prouuttions, it was requisite that tliey should have nitrehaiUs, or carriers, to disperse them over the continent. A wanddtirig shepherd tribe, who inhabited the neighbouring country, seeii»ed by their roaming and unsettled mode of lite, to be peculiarly qualified for that cmploymcrit. These people difi'ered much in their ap- pearance from the Ethiopians ; having long hair, Eu- ropean features, and very dark complexions, though without any resemblance to the black moor, or negro. Fixed to no certain residence, they drove their nume- rous flocks from place to place, and erected their movea- ble huts wherever the pasture seemed most luxuriant, or the stream mo:it refreshing. By conducting the trade of the Cusliitcs, they became a great and powerful people ; their flucks increased in number, and their ter- ritory was enlarged. They occupied a narrow tract of land along the Indian Ocean, and afterwards along the Red Sea, to the ports of which they carried their mer- chandise ; but their principal residence was in that level region which lies between the northern tropic and the nrountains of Abyssinia. This extensive country, which is now called Beja, stretches along the sea-coast from Masuah to Suakem,then turning westward, continues in that direction, having the Nile on the south, and the tropic of Cancer on the north, till it reaches the deserts of Selima, and the confines of Libya. The next district v/hich they possessed was Meroe, or, as it is now called, Atbara, lyuig between the rivers Nile and Astaboras. Another territory belonged to them, which is now called Derkin, a small plain stretching from east to west, be- tween the river Mareb and Atbara. But tlie noblest and most warlike of all the Shepherds were those which inhabited the mountains of the Habab, extending from the neighbourhood of Masuali to Suakem. These shep- herds were distinguished by various appellations, proba- bly denoting their various degrees of rank. Some were called simply Shepherds, whom we may suppose to have been tlie lowest class. Some were called Hycsos, shep- herds armed, or wearing harness, and were probably the national soldiers. Ag-ag, is thought to have been the appellation of their nobles or chiefs, whence arose the title of king of kings. It was the hereditary name of the king of Amalek, whom Samuel hewed in pieces, and who was an Arabian shepherd. The power of the Shepherds was greatly augmented after the building of Carthage, as the extensive carriage of that commercial city fell into the hands of the Leha- bim, Lubim, or Libyan peasants. In those early ages, the want of navigation was supplied by immense multi- tudes of camels; and we find that, even before the days of Joseph, the Ishmaelite merchants, with the help of these animals, traded to Palestine and Syria, from the southern extremity of the Arabian peninsula. The Shepherds, tliough in general the friends and allies of the Egyptians, were sometimes their most formidable enemies. They were united, indeed, by mutual interest ; hut no cordial amity could be expected between two nations, whose manners and religion were so much at variance. The cow, which the Egyptians worshipped, the Shepherds slaughtered for food ; and, while the idolatry of the former converted into objects of adoration the most vaiclean animals, and the vilest reptiles, the latter paid their pvu-er and more rational homage only to the luminaries of heaven. But besides the Cushites and Shepherds, Abyssinia is inhabited by nations of a fairer complexion, who, though of various names, are all comprehended under the general denomination ot Hahbesli, sigiiilying a num- ber of distinct people, assembled by accident in one place. The chronicle of Axuin, the most ancient his- tory of this counliy, whose autiiority, next to that oi the Holy Scriptures, is held most sacred Ijy tbe Abyssinians, gives the following account of the original settlement of these various nations. Abyssinia, according to this his- tory, was never inhabited till 1808 years before the birth of Christ. Two hundred years after that period, it was laid waste by a flood, which so deformed and altered the face of the country, that it received the name of Ourc Midra, a country laid waste ; or, as it is expressed by Isaiah (xviii. 2) a land w/iic/i the ivaters or Jioods had ■sjwiled. About 1400 years belore the nativity, it was peopled by a variety of nations, speaking different lan- guages, who settled unmolested in the high lands of Tigre, among the Agaazi or Shepherds, with whom they were in friendship. The most considerable of these nations settled in the province of Amhara, origi- nally as little known as any of the recent establishments ; but upon a revolution which took place in the country, the king fled thither with his court, and remained so long, that the Geez, or language of the Shepherds, was dropt, and would have become totally obsolete, had not the sacred writings been translated into that dialect. The nation second in consequence, was the Agows of Damot, a province in the south of Abyssinia, where they are settled immediately upon the sources of the Abay. The next are the Agows of Lasta, called like- wise Tcheratz Agow, from Tchera, their principal re- sidence ; these people live in caverns, and seem to worship the Tacazze with the ^ame degree of venera- tion which the Agows of Damot pay to the Abay, or Abyssinian Nile. There is still another of these nations, named Gafat, who dwell near Damot, on the southern banks of the Abay ; and who, according to their own declaration, ever have been Pagans, as they now are. Thus, the different nations who possessed Abyssinia, were the Cushites, the Shepherds, Amhara, Agow of Damot, Agow of Tchera, and Gafat. In conformity with the Axum chronicle, which mentions that the four last of these nations had emigrated from Palestine, ]\Ir Bruce contends that they were Canaanites, who escaped from the cruelty of the Israelites, when they took pos- session of the promised land. His theory is contrary to probability, and unsupported by facts. It rests chiefly on the coincidence between the period of the invasion of Canaan, and the entrance of these strangers into Ethiopia ; and on the testimony of Procopins, w ho men- tions that, in his time, two pillars were standing on the coast of Mauritania, which bore this inscription in the Phoenician language : " We are Canaanites, flying from the face of Joshua the son of Nun, the robber." Were the first of these arguments admitted, it would not be difficult to indentify the negroes imported to our West Indian colonies from the coast of Guinea, with the ad- venturers who emigrate, at the same period, to the American continents, from the Highlands of Scotland ; and, as the authenticity of the inscriptions mentioned by Procopius is much disputed, they cannot fairly be ad- duced in proof of any historical fact. j\Ir Bruce's opinion, that the Ethiopians spoke the original language, and were the first inventors of writing, must be as- cribed to the same fondness for theory, by which he seems to have been too frequently misled. It is pertain. 48 ABYSSINIA. however, that they wore, in ancient tiines, a learned and civilized people ; how tliey came to be degraded into their present state of barbarity, is a phenomenon as un- accountable and striking, as the degeneracy of their neighbours, the Egyptians. According to an extravagant fiction, the Ethiopians, who possessed the country of Thcbais, made an irrup- tion into Lower Egypt, while the Jewish legislator re- sided in that country ; penetrated as far as Memphis ; and, having defeated the Egyptians, threatened the kingdom with total destruction. By the advice of the oracles, Moses was intrusted with the conniiand of the Egyptian forces, and immediately prepared to invade the enemy's country. Instead of marching along the banks of the Nile, where the Ethiopiajis were ready to oppose him, he led his army through some of the in- terior countries, which were nmch infested \\ith serpents. To protect his men from these dangerous animals, he carried along with him a number of panniers, formed of the papyrus, which he filled with the birds named ibis, and, as soon as he approached the tract where the rep- tiles abounded, he let out a sufficient number of these birds, which, by destroying the serpents, cleared the way for his army. The Ethiopians, thus surprised in their own country, where they had no dread of invasion, were easily defeated in the field, and took refuge in their capital Meroe, a city rendered almost impi-egna- ble by three rivers flowing round it, the Astapus, the Astaboras, and the Nile. The daughter of the Ethiopian monarch became enamoured of Moses, whom she had seen from the walls ; and offered, on condition of his swearing to marry her, to open the city to the assailants. Moses complied ; but stained the gloiy of his conquest by his cruelty towards the inhabitants. He plundered their city, put many of them to the sword, ravaged the whole country, and dismantled their places of strength. He then returned in triumph to Egypt, after having been absent for ten years on this expedition. From the invasion by Moses till the ;queen of Sheba's visit to Jerusalem, we have no particulars of the history of Ethiopia. The Abyssinians, who suppose that prin- cess to have been sovereign of Ethiopia Proper, tell us, that, having heard from Tameran, an Ethiopian mer- chant, of the surprising opulence and wisdom of Solo- mon, she resolved to ascertain in person tlie truth of his report. Though she had been a Pagan before un- dertaking this journey, she was so struck with the grandeur of the Jewish monarch, and the extensive knowledge which he displayed, that she immediately tecame a convert to the true religion. It is added, that she became pregnant by Solomon, and, on returning to her own country, was delivered of a son, to whom she gave the name of Menilek, another self. Some years after, Menikk was sent to his father's court, where he was carefully instructed in the learning and institutions of the' Jews, and crowned king of Ethiopia, in the temple of Jerusalem, receiving from Solomon, at his inaugura- tion, the name of David. After remaining for some time in Judea, he was accompanied to Ethiopia by many Israelites of distinction, and particularly by twelve doc- tors of the law, chosen from the twelve tribes, among whom was Azariah the son of Zadoc, the high priest. These introduced into Abyssinia the religion of Moses, and framed after Jewish models the civil and sacred in- stitutions of the country. Mr Bruce supposes, with great probability, that this princess was queen of the territory named Saba or Azab ; an opinion which coin- cides more exactly tliau any other, witii iht deacriplloa which our Saviour has given of her, "as queen of the south, coming from the ultcrmosl parts of the earth." She is called by the Arabs Bclkis, and Makeda by the Abyssinians. She crijoyed the sovereignty for forty years, and, before her death, she boun(l her subjects by three remarkable laws: 1st, That the crown should be hereditary in the family of Solomon : 2dly, That, after her, no woman should be allowed to inherit the crown, or to reign as queen, but that it should descend to the heirs-male, however distant, to the exclusion of all female heirs, however near ; and tiiat these two articles should be considered as the fundamental and unalterable laws of the kingdom : Lastly, she enacted, that the heirs- male of the royal family should be imprisoned on a high mountain, where they were to continue till death, or till the course of succession should call them to the throne. Having established these regulations in a manner not to be revoked, Makeda died in the 98Gth year be- fore the birth of Christ, leaving her son Menilek to succeed her, whose descendants, if we may believe the Abyssinian annals, have ever since continued to occupy the throne. In the reign of Menilek, the empire was in- vaded by Shishak, king of Egypt, who plundered the temple of Jerusalem, under Rehoboam. A rich temple which had been erected at Saba, the capital of the Ethiopian empire, underwent a similar fate ; and it was probably on this occasion that Menilek removed the seat of government to Tigre. Many circumstances concur to prove, that Shishak was no other than the celebrated Sesostris, and was the first Egyptian monarch who had made conquests in Ethiopia. Scripture indirectly as- cribes to Shishak the sovereignty of this country ; and Herodotus explicitly asserts, that Sesostris was master of Ethiopia ; though neither in sacred nor profane history is it elsewhere related, that this empire was ever subject to any other Egyptian. From the death of Shishak till the days of Cyrus the great, there is a chasm in the history of Abyssinia which can only be filled up by theory and conjecture. That conqueror is said to have subdued Ethiopia ; but the inhabitants having revolted after his death, Camby- ses, his successor, attempted in vain to reduce them to submission. Before he undertook tliis expedition, he sent ambassadors to the king of the Macrobii, under pretence of soliciting his alliance, though in reality he only wished to ascertain the strength of the country. The Etliiopian monarch, aware of his design, disdained tlie rich presents which Cambyses had sent him ; re- proached the ambassadors with the injustice and am- bition of their sovereign, and delivered to them a bow, with these remarkable words : " Cany this bow to your master, and till he can find a man able to bend it, let him not talk to us of submission." This resolute an- swer so exasperated Cambyses, that he instantly began his march, witliout taking time even to procure the ne- cessary provisions for his army- A famine of conse- quence ensued among them, which became at last so dreadful, that the soldiers were compelled to devour one another ; and Cambyses finding himself in immi- nent danger, marched back his army with prodigious loss. Even if he could have effected his march into the heart of the empire, he would probably have failed in the object of his expedition; for Ethiopia had been strengthened, but a short time before, by an accession of 34,000 Egyptians. These fugitives had been sta- ABYSSINIA. 49 tioued by Psamnienitus in dift'crcni places on the fron- tiers, and, having continued there for three years without being relieved, revolted to the emperor of Ethiopia, wlio placed Iheni in a country disaffected to him, order- ing them to expel the inhabitants, and to occupy their territory. Curiosity induced Ptolemy Euergetes to invade this country, for tlie sole purpose of discovering the source of the Nile. Though no historian has recorded the par- ticulars of his expedition, it appears from an inscription copied by Cosnius Egyptius, from a white marble chair, which stood at the entrance of Adule, one of tl'.e cities of Ethiopia, that he had penetrated into the fiirt!ie->t parts of the empire ; subdued its most powerful nations ; and, af- ter all his conquests, assembled his army at Adulc, where he sacrificed to Mars, Neptune, and Jupiter ; and, in gratitude for his success, dedicated to Mars a white marble chair. In the reign of Augitstus, when the Roman forces were drawn out of Egypt, for the purpose of invading Arabia, Candace, queen of Meroe, took advantage of their absence, to make an irruption into the province of Thebais. As she met with no force to oppose her, she proceeded, for some time, with great success ; but being at length apprised that Pctronius, governor of Egypt, •was hastening towards her with a powerful army, she retired with precipitation into her own dominions. Pe- tronius overtook her at Pselcha, where, with not more than one-third of the number of men which composed the Ethiopian army, he gained an easy victory over those undisciplined savages, who were armed only with poles, hatchets, or bludgeons. He reduced the most important fortresses of the country ; but, notwithstand- ing his success, was obliged, soon after, to withdraw his soldiers, who were unable to sustain the excessive heat of the climate. Candace afterwards sent ambassadors to Rome, who gratified Augustus with sucli magnificent presents, that he was induced to grant tlieir queen a peace on terms of her own proposing. The Romans, from that time, accounted themselves masters of Etlii- opia; and Augustus was congratulated on having com- pleted the conquest of Africa, by reducing a country till that time unknown. The conquest, hov. ever, was mere- ly nominal, for Meroe continued under the government of its wonted sovereign. Queens, who were distinguish- ed by the general title of Candace, as the Roman empe- rors by that of Csesar, had reigned in that country for many generations ; and we learn, from the story of the Ethiopian eunuch, that it still continued, in the reign of Tiberius, to be governed by a princess of the same name. During the reign of Abreha and Atzbeha, (translated by Mr Bruce, Jbraham the blessed) who ascended the throne about 327 years after the Christian era, Mero- pius, a philosopher of Tyre, by nation and religion a Greek, set sail for India from a port on the Red Sea, tak- ing along with him Frumentius and Qidesius, two young men on whom he had bestowed a very liberal education. Their vessel was cast away on the rocks of the Abyssi- nian coast, and Meropius was slain by the barbarous na- tives, while acting bravely in his own defence. The youths were conveyed to Axum, then the capital of the kingdom and the residence of the court, where they soon displayed the superiority of a cultivated mind. The Abyssinians regarded them as prodigies : CEdesius was set over the king's household and wardrobe, an of- fice which has always been held by a stranger; and Frumentius was intrusted by the Iteghe, or queen dow- VoL. I. Part I. agcr, with the charge of the young prince's education, to which he devoted himself with the most faithful as- siduity. Having imlnied the mind of his p\ipil with all the learning of the times, he inspired him with a love and veneration for the Christian religion. After this he visited Athanasius, who had been leccnt- ly elected Patriarch of Alexandria, related to him the progress he had made towards the conversion of the young monarch, and the sanguine hopes which he en- tertained of seeing the Christian religion estalilished in Ethiopia. Athanasius, delighted with the prospect ol such an accession of proselytes, consecrated Frumentius bishopof Axuma ; who, returning immediately to enter on his new office, found his royal pupil completely dis- posed to favour his pious design. He made an open avowal of the Christian faith; his example was followed by the greater part of his subjects ; and, amidst the nu- merous heresies which then prevailed in the East, the church of Ethiopia remained uncontaminated, so long as it was superintended by its first bishop and apostle. It was during this reign that the Abyssinians under- took the expedition, celebrated in Arabian story under the name of the War of the Elelihant. In the middle of the Arabian peninsula stood a temple, which, for about fourteen centuries, had been held in the highest venera- tion ; for it was built, say the Arabs, on the spot where Adam had pitched his tent when driven from Paradise, and contained the black stone on which Jacob reposed his head, when he saw the vision of the angels descend- ing and ascending on the ladder, that reached to heaven. The multitude of strangers, who resorted from the sur- rounding nations to this sacred place, suggested the idea of rendering it the emporium of the trade between India and Africa. Part of Arabia seems, at that time, to have been in possession of the Ethiopians, and Abreha, to divert the trade into a channel more convenient for his own dominions, built a large temple in the country of the Homerites, near the Indian ocean, on which he bestow- ed all the privileges enjoyed by the temple of Mecca. Alarmed at the prospect of having thefr city deserted, the Arabians entered the temple of Abreha by night, and after burning as much of it as could be consumed, pollu- ted the rest with every mark of indignity. To revenge this sacrilegious insult, Abreha, mounted upon a white elephant, marched against Mecca with a powerful army, resolving to level its temple with the ground. His fury was diverted by the stratagem of Abow Talcb, Maho- met's grandfather, who was then keeper of the Caaba, or round tower. He persuaded his countrymen to make no resistance to the Ethiopian army; presented him- self before Abreha early on his march ; and, by false in- telligence, directed his vengeance from Mecca against the rival temple of Osiris at Taief, which Abreha razed to its foundations, and then prepared to return to his own kingdom. It was not long before he was convinced of his mistake, and Mecca would have soon fallen a victim to his indignation, had not Heaven interposed for the protection of that holy city. A flock of birds, called Aba- bil, came from the sea, having faces like lions, and each holding in his claws a stone like a pea, which they let fall upon the Ethiopians in such numbers, that every one of them was destroyed. A less miraculous account of their destruction is, that, during the siege of Mecca, the small-pox made its appearance ; and the investing anny were the first of its victims. It is said, that after the death of Abreha, the court, ajid principal people of Abyssinia, relapsed into idolatry, G 50 AHYSSINIA. which conlinucd lo prevail till the year 521, when they were again converted by their king Adad, or Aidog, pro- bably the same with Caleb, or Elisbaan. That monarch was engaged in war witli .lie Homeritcs, or Sabaeans, in Arabia telix, and, having dcl'eated their armies, and subverted their kingdom, he embraced the Christian re- ligion, m token of gratitude to its auth6r, to whom he ascribed his success. Soon alter this event, a violent persecution of the Christians broke out in Arabia. At an early period, the Jewish religion had penetrated far into that penmsula ; and, after the temple had been destroyed by Titus, its professors were strengthened by such an accession of numbers and of wealih, as enabled them to establish several independent prmc.palities. In the Neged, and even as far as Medina, petty sovereigns started up, whose knowledge and practice in war rendered them ex- tremely formidable to the commercial and eflcminate Arabians. These people persecuted the Christians witn the most inveterate hatred. Phineas, one of their princes from Medina, having defeated the governor of Najiran, ordered furnaces, or pits full of fire, to be pre- pared, into which he threw as many of the inhabitants of that place as refused to renounce the Christian reli- gion. The governor St Aretas, with ninety of his com- panions, fell victims to his cruelty. Justin, the Greek emperor, could give no relief to these afflicted Chris- tians, as he was at that time engaged in an unsuccessful war against the Persians ; but, in the year 522, he sent an embassy to the king of Abyssinia, entreating him, since he too was now a member of the Greek church, to interfere in favour of the Christians of Najiran. Ca- leb, on receiving this message, commanded his general Abreha, governor of Yemen, to march to the aid of young Aretas, who was then collecting troops to revenge his father's death. The ardent warrior strengthened by this remforcement, would not wait till the arrival of the emperor, who had promised to follow Abreha with a pcvverful army. He came up with Phineas, while lie was ferrying his troops over an arm of the sea; the Jewish forces were completely routed, and their general himself, to escape being taken, was compelled to swim on his horse to the nearest shore. In a short time af- terwards, the emperor with his army crossed the Red Sea ; and Phineas, hazarding a second battle, was again defeated. But, notwithstanding tlicse misfortunes, none of the Jewish principalities seem, at that time, to have been overturned. When Mahomet promulgated his pretended revela- tion, the Ethiopian governor of Yemen became a convert to his doctrines ; but there seems to be no truth in the story so eagerly propagated by the Arabian historians, that the king of Abyssinia himself embraced the new religion. Froin this time the Abyssinians lost all the power which they had formerly enjoyed in Arabia. The governors were expelled by Mahomet and his suc- cessors, and, taking refuge in Africa with great num- bers of their subjects, established there the kingdoms of Adel, Wypo, Mara, Tarshish, Iladea, Aussa, and several others, which soon rose to importance for power and opulence. The successors of Mahomet, in the progress of their victories, had expelled the Jews by violence or oppres- sion from their dominions in Palestine, Arabia, and Egypt. Abyssinia, unsubdued by these fierce enthusi- asts, afforded an asylum to the fugitives, the more invit- ing, as their countrymen had already a powerful estab- lishment in that empire. There was one Jewish family which had always preserved on the mountain of Samen an independent sovereignty, and the royal resiuencc was on the summit of a liigh pointed clin, called Irom that circumstance, the Jtiu's Hock. Several other rug- ged and inaccessible mountains were occupied by that people as natural iortrcssesi and their strength was so mucn increased by the numbers of their countrymen who fled before the conquering Mahometans, that they began to meditate a revolution in Abyssinia, in favour of then- own rcligon. Many circumstances concurred to facilitate their design. The Abyssinians, distracted by various heresies, were more inclined to embrace any other religion, than to yield one disputed point to their Christian adversaries; the country, desolated by pesti- lence and war, suffered, moreover, all the multiplied evils which usually prevail under the government of a minor; and Judith, the daughter of tlie Jewish king, a woman of unbounded ambition, and of singular talents for intrigue, had lately been married to the governor of Bugna, a small district in the neighbourhood of Lasta, both which countries were strongly prejudiced in favour of Judaism. This artful and aspiring woman had form- ed so powerful a faction, that she resolved to usurp the throne of Abyssinia, and to extirpate the family of Solo- mon, who had continued since the days of Makeda, to reign in uninterrupted succession. With this design, she surprised the almost inaccessible mountain of Danio, where the royal princes were at that time confined, and massacred every one of them, to the number, it is said of four hundred. Fortunately the nobles of Amhara, on hearing of this catastrophe, conveyed the infant king Del Naad, the only surviving prince of his race, into the loy- al province of Shoa, and thus the line of Solomon was preserved ; and at length, after an interval of some ages, restored. Judith immediately mounted the throne, to which she had thus paved her way through blood ; and, in defiance of one of the fundamental laws of the kingdom, that no woman should be permitted to reign, not only enjoyed the sovereignty undisturbed during forty years, but trans- mitted it in peace to her family ; five of whom succes- sively swayed the sceptre of Abyssinia. Of the trans- actions of these reigns nothing is recorded ; except that, during this whole period, the kingdom was a scene of murder, violence, and oppression. By a new revolution, of which the history Is now lost, the descendants of Ju- dith were supplanted by relations of tlieir own, a noble family of Lasta. The reign of these princes was distin- guished by the restoration of Christianity, and the gen- eral mildness of their government. The kingdom, un- der them, recovered from the misfortunes which had long overwhelmed it ; and their names are still pre- served with gratitude and veneration. But as they were not of the line of Solomon, and, of consequence, were accounted usurpers, the history of none of them is recorded in the annals of the nation, excepting that of Lalibala, w ho was revered as a saint, and who reigned, with great splendour, about the beginning of the thir- teenth century. At that time, the Saracens, havmg conquered Egypt, persecuted the Christians in that country with great rigour, and particularly the masons and hewers of stone, whom they detested as the promoters of idolatry, by the ornaments with which they embellished their works. Lalibala opened an asylum for those Egyptians, of whom prodigious mimbers resorted to his dominions ; and re- ABYSSINIA. 51 solved to render tlicm userul to the country from wliich they received protection. He h;id loni^ admired the ca- verns ol" tlie ancient Troglodytes ; and the lirsl work in which lie employed the Egyptians, was to hew churches, after these speciniens, out of the rocks of his native coun- try Lasta. These churches still remain entire, having large columns formed out of the solid adamant, with every species of ornament that can be executed in build- ings above ground. He next engaged in the more ar- duous attempt to lessen tlie stream of the Nile, that it might no longer fertilize the land of Egypt, possessed, at that time, by the enemies of his religion. I5y an exact survey and calculation, he had discovered, that several of its tributary streams, which issued from the highest part of the country, could be directed into the low coun- try to the south, instead of taking a northern course, and thus augmenting the Nile. It said, that he succeeded so far as to intersect two of its largest branches, which have ever since flowed into the Indian Ocean. He was next pioceeding to carry a level towards the lake Za- waia, the reservoir of many of the streams which flow into the Egyptian river; which would certainly have been very sensibly diminished by the loss of so much water. Death interposed to prevent the execution of this stupendous design; though there is at Shoa a writ- ten account, which states, that he was dissuaded from his undertaking by certain monks, who represented to him the danger of enriching, by so many fine rivers, the kingdoms of Hadea, Add, and Mara, which would thus be rendered so populous and powerful as to rival the em- pire of Aliyssinia, or, at least, to become altogether in- dependent of its authority. Alvarez informs us, that Roderigo de Lima, the Portuguese ambassador, saw the remains of these works in the year 1522, and travelled among them for several days. Ever since the usurpation of Judith, the descendants of Del Naad had continued to rule over the loyal pro- vince of Shoa, without having made one attempt towards recovering their ancient sovereignty. But what they despaired of effecting by force of arms, they obtained from the magnanimous generosity of the grandson of Lalibala. Tecla Haimanout, who had been ordained Abuna, and who is celebrated as the founder of the monastery of Dcbra Libanos, had acquired, by the sanc- tity of his character, and his love for his country, an un- limited influence over the mind of Naacucto Laab, the reigning monarch, a prince remarkable for the integrity of his principles, and the benevolence of his disposition. He was easily persuaded by the Abuna, that his crown, though transmitted to him from his ancestors, whose virtues had rendered it illustrious, could never be puri- fied from the stain of usurpation ; and he willingly re- signed it to Icon Amlac, of the line of Solomon, then reigning in the province of Shoa. In consequence of the mediation of Tecla Haimanout, a treaty was con- cluded between these two princes, in which it was sti- pulated, that Icon Amlac should ascend the throne of Abyssinia ; but that a portion of territory in Lasta should be granted in absolute property to Naacueto Laab, and his heirs ; that, in token of their former grandeur, they should retain the emblems of sovereignty ; be free from all public burdens ; and be styled kings of Zague, or the Lasta kings. Nor did the Abuna forget his own interest in this mediation. By one of its articles he obtained a third of the kingdom for the maintenance of his own dignity, and for the support of the clergy, convents and churches throughout the empire ; and by another it was decreed, that, after him, no native Abyssinian should be chosen Abuna, even although he should be ordained at Cairo. " Tlie part of the treaty most liable to be bro- ken," as is well observed by Mr Bruce, " was that which ei-ected a kingdom within a kingdom. However, it is one of the remarkable facts in the annals of this coun- try, that the article between Icon Amlac, and the house of Zague, was carefully observed for near 500 years. It was made before the year loOO, and was never vio- lated till the treacherous murder of the Zaguean prince, in the unfortunate war of Begemder, in the reign of Joas, 1768. Icon Amlac, though now sovereign of Abys- sinia, continued to reside in the province which had been so faithful to his family. He reigned a considera- ble time ; and was succeeded on the throne by five dif- ferent princes in the same numlaer of years. The cause of this rapid succession of sovereigns, and the events which happened in their reigns, are equally unknown to us ; nor have we any account of the trans- actions of the empire till the days of Amda Sion, who began to reign in the year 1312. He was the son of Wedem Araad, who was the youngest brother of Icon Amlac. Amda Sion was his inauguration name, by which he is generally known ; his Christian name was Guebra Mascal. The first actions of his reign were disgraceful to humanity, and very different from the character which he ever afterwards maintained. Not content with living publicly with his father's concubine, he soon after committed incest with his two sisters. Honorius, a monk, who was afterwards canonized for his sanctity first exhorted him to repentance, and then pub- licly excommunicated him for these infamous crimes. The refractory inonarch, instead of sinking under this sentence, ordered Honorius to be whipped through the streets of his capital. That very night the town was re- duced to ashes by fire, arising, through the just ven- geance of Heaven, from the blood of the outraged saint. Such at least was the account which the clergy gave of this catastrophe ; but the king, convinced that they themselves were the incendiaries, banished them into those provinces, of which the inhabitants were chiefly Pagans or Jews, where they were extremely successful in propagating the Christian religion. The licentious conduct of Amda Sion had produced, in the neighbouring nations, such a contempt for his government, that, while he himself was embroiled with Honorius and the monks, one of his factors, who had been charged with his commercial interests, was robbed and assassinated by the Moors, in the province of Ifat. Impatient to revenge this outrage, he suddenly assem- bled his troops, and ordered them to rendezvous at Shugura, upon the frontiers ; while, attended by only seven horsemen, he fell upon the nearest Mahometan settlements, putting all he met with to the sword. He then placed himself at the head of his army, and desolated the whole country, carrying off a prodigiovis bootV. The Moors, astonished by the unexpected activity of this monarch, whom they had despised as an effeminate voluptuary, assembled in great numbers to oppose him ; and, hearing that he was left with scarcely a sufficient number of soldiers to guard the camp, they resolved to attack him before break of day, imagining that he coutd not possibly make any effectual resistance. Fortunate- ly two detachments of his army had joined him the night before : these he drew up in battle array, and, when the Moors presented themselves, he attacked them with G 2 S'2 ABYSSINIA. resistless lury, slew Uieir gencfal uith his own hand, and, animating his iioops by his example, obtained a de- i;isive victory. He then commanded his soldiers to build huts lor themselves, and to sow the adjacent lands, as if he intended to continue during the rainy season in the enemy's country. Terrified at the prospect of being iotally extirpated, the Moors readily subnuttcd to the tribute which he imposed ; and the king, already ad- mired for his valour, conciliated still farther the af- ieetious of his subjects, by distributing among them his own share of the plunder. Even the priests, whom he had so much oflended, now extolled his mui)ificence to the churches, and his zeal against the enemies of the cross. Scarcely had the Abyssinians returned to their own country, when the Moors prepared for another revolt. A combination w^as formed by Amano king of Hadea, Saber-eddin, whom Amda Sion had made governor of Fatigar, and secretly by Gimmel-eddin, governor in Dawaro. The king endeavoured to conceal his know- ledge of their conspiracy, that, without awakening their suspicions, he might prepare an army powerful enough to crush them, before they had time to unite their for- ces. The Moors, though fully apprised of his prepara- tions, facilitated by their own precipitation the comple- tion of his design ; for, without any regular plan of operation, they suddenly commenced hostilities, by plun- dering some Christian villages, and destroying their churches. The royal army was despatched against the rebels in three separate detachments. Amano, king of Hadea, who, by the advice of a conjurer, had resolved to wait in his own dominions the approach of Amda Sion, whom, it was decreed, he should deprive at once 6f his kingdom and his life, was surprised by the gene- ral of the cavalry, his army completely routed, and him- self carried prisoner to the capital. Saber-eddin was next brought to an engagement by the governor of Am- hara, who gained a decisive victory, laid waste the rebel's country, and made captives of his wife and chil- dren. Meanwhile intelligence was received, that the I'alasha likewise were in rebellion, and had already taken the field with a formidable army. By the king's com- jnand, Tzaga Christos, governor of Begemder, assem- bled the troops of his province, with those of Gondar, Sacalto, and Damot ; overtook the rebels, before they had time to commit much devastation, defeated them with great slaughter, and forced the survivors to con- ceal themselves among their fastnesses in the moun- tains. The kuig himself had proceeded with a small detachment of his army to Dawaro, to keep the govern- or of that province in awe ; and, having now completely succeeded in quelling the rebels, was preparmg to re- turn with his victorious forces, when he was informed that the kings of Adel and Mara had resolved to give him battle. Exasperated by this intelligence, he pre- pared to pursue his enemies with the most signal ven- geance. To give greater solemnity to his resolution, he assembled the principal officers of his army, and, sur-- rounded by his soldiers, pronounced before a monk of noted sanctity, and arrayed in his sacerdotal habit, a Song invective against the Mahometans ; recounted the improvoked injuries which, at the instigation of the ■kings of Adel and Mara, they had committed against him ; enumerated the atrocities of which they had been guilty ; disclaimed all avaricious motives in undertak- ing the war, declaring, that he would appropriate no ?>art of the spoil which was stained with the blood of his subjects, more valuable to him than all the riches ot Adel ; and concluded with swearing on the holy cu- charist, that, though but twenty of his army should join him, he would not turn his back upon Adel or Mara, till he had either forced them to submit as tributaries, or had utterly extirpated them, and annihilated their re- ligion. The soldiers were fired by his enthusiasm ; and, to show themselves as disinterested as their sovereign, took lighted torches in their hands, and set fire to all the rich spoil which they had acquii'ed in the province of Fatigar. Having thus satisfied their consciences that they were the true soldiers of Christ, they set out on their march, thirsting, not for the wealth, but the blood of the infidels. Their ardent impetuosity was checked by the obsta- cles to which their own superstition gave rise. The Abyssinians believe, that the world is possessed, during the night, by certain genii unfriendly to mankind, dis- turbed by the slightest motion, and implacable in their revenge. To such a degree does the dread of these spirits prevail, that an Abyssinian will not venture, at night, even to throw a little water out of a basin, lest it should violate the dignity of some vindictive elf. The Moors deride these superstitious fears, and frequently turn them to their own advantage. Protected by averse of the Koran, sewed up in leather, and worn round their neck or arms, they bid defiance to the power of the most malignant genius, and engage without scruple in any nocturnal enterprise. In their wars with the Abyssinians, night is their favourite season of attack ; and, in the present campaign, they resolved to avoid a pitched battle, and to harass the king's army in the dark. The troops of Amda Sion, though they had always the advan- tage, were soon wearied out by these nightly skirmishes ; and, on the commencement of the rainy season, insisted on bemg allowed to return. A prince of such a martial disposition, naturally resented a proposal which betray- ed their deficiency in steadiness and discipline. He therefore desired his officers to acquaint them, that, if they were afraid of rains, he would conduct them to Adel, where there were none ; and that, for his own part, he had resolved not to quit the field, while there was one village in his dominions that did not acknow- ledge him as sovereign. On hearing this remonstrance^ the army again set forward ; but, being still harassed by the nightly attacks of the Moors, the spirit of mutiny began once more to prevail. The eloquence of the king brought them back to a sense of their duty ; but imme- diately afterwards he was seized with a violent fever, which seemed to threaten his life. While, in consequence of his illness, the soldiers expected every moment an order to return, they accidentally received intelligence, that an army of 40,000 ^oors was advancing towards them, and was then at no great distance from the camp. The king, though now free from fever, was so excessive- ly feeble, that he fainted while his servant was employed in putting on his armour. His resolution, however, was unalterable ; and, after recovermg from his swoon, he addressed his soldiers in a speech full of enthusiasm, exhorting them to confide in the righteousness of their cause, and in the continuance of that favour which they had hitherto experienced from heaven. Animated by this address, his soldiers were now only solicitous, that, in his present feeble state, he should not expose his per- son in battle ; and he promised to comply with their re- quest. But the whole army was soon thrown into con- sternation, by a report that tlie Moors had poisoned the ABYSSINIA. 53 wells, and enchanted all ihc streams in front of the camp. Tliough a priest of great sanctity was employed to dis- enchant the waters, and a river was consecrated by the name of Jordan, the soldiers not only refused to advance, but resolved immediately to return home. The king- rode through the ranks in the most violent agitation, and conjured them to remember their lormer valour, and the solemn oaths by which they had repeatedly bound themselves to remain true to the cause of their sovereign and their religion. Finding that his arguments produced no efi'ect, he begged, that those who were unwilling to light, would only stand in their places as spectators of the bravery of their comrades. He then ordered the master of the horse, with only five others, to attack the left wing of the enemy ; while he hunself, with a small party of his servants, made a furious onset on the right. His valour was crowned with success. Weak as he then was, he slew with his own hand the two leaders of the right wing; his son, who fought on the left, des- patched another officer of rank ; and the soldiers, ashamed of their conduct, and alarmed for the safety of their valiant monarch, rushed furiously to his rescue. The centre and left wing of the enemy was entirely de- feated ; the right wing, consisting Chiefly of Arabians, ictreated in a body ; but, ignorant of the country, enter- ed a deep valley, surrounded by perpendicular rocks, which were thickly covered with Avood. Amda Sion, perceiving their situation, attacked them with a few of his troops in front, while otners rolled great stones npon them from the top of the rocks ; and thus, being unable either to resist or escape, they all perished to a man. Another division of the army was sent, under the com- mand of the master of the horse, in pursuit of the rest of the Moors. They found these unhappy people, ex- liausted by the fatigues of the combat and of flight, lying by the side of a water, which they lapped like dogs ; and, in this helpless situation, they were slatigh- tered without resistance by the relentless conquerors. Wearied at length with murder, they made prisoners of the few who survived. Among these were Salck king of Mara, and his queen ; the former of whom was hanged by the order of Amda Sion, the latter hewn to pieces by the soldiers, and her body given to the dogs. Pursviing his advantages, the Abyssinian monarch advanced still farther into the Mahometan territories, till lie reached the dominions of the king of Adel. That prince, rendered desperate by the devastation of his country, and the prospect of its total ruin, resolved to make one last effort for its preservation. He therefore took the field against the Abyssinians, but conducted himself with less prudence than his own situation ?ind the character of his adversary required. Victory again declared in favour of Amda Sion ; the king of Adel fell in the engagement; and his troops, dispersed in all di- rections, were intercepted by detachments of the Abys- sinian army, which had been placed in ambush to prevent their escape. After this disastrous event, the sons of the late king, dismayed by the prospect of inevitable destruction, wait- ed upon Amda Sion with valuable presents ; and, pros- trating themselves in the dust before him, besought him to pardon the injuries which they had committed, and assured him of their readiness to submit to his dominion, provided he would advance no farther into their country, but spare the lives and property of their afflicted sub- jects. The stern conqueror rejected their entreaties with indignation; reproached them with the enorniities which they had perpetrated against his Christian sub- jects; told them, that he had proceeded thus far into their kingdom to inllict the punishment (hie to their crimes; and eonunandcd them to return and expect the approach of his army, as he would never turn his back upon Adel, while he had ten men capable of drawing their swords. The two eldest princes, with their uncle, who had accompanied them, were overawed by the- fierce demeanour of the Abyssinian ; but the youngest made a spirited speech, in which he complunented him on his unparalleled valour, and entreated him not to sully his fame by the oppression of a people already con(|uered and defenceless. The only answer he could obtain was, that unless the queen, his mother, with the rest of the royal family, and the principal people of the nation, should surrender themselves next evening at his tent- door, as he had done, he would lay waste the kingdom of Adel, from the place where he then sat, to the Indian Ocean. Rather than submit to such cruel terms, the Adelians resolved to try once more the fortune of war; and bound themselves, by mutual oaths, to stand by each other to the last extremity They informed the young princes of their resolution ; and requested them to seize the first opportunity of escaping from the camp of Amda Sion, and take the command of the army, every man of which was ready to conquer, or die in their cause. Pro- voked by their obstinacy, the Abyssinian monarch divided his army into three detachments ; two of which were commanded to enter the enemy's country by different routes, while he himself marched directly to the spot where the Adelians were encamped. An obstinate en- gagement ensued, in which the young king of Wypo particularly distinguished himself, opposing Amda Sion wherever he appeared, and exhorting his troops to re- main firm to the last. At length, the Abyssinian monarch, observing the exploits of this young warrior, grasped a bow in his hand, and took so just an aim, that he shot him through the middle of the neck, so that, his head declining to one shoulder, he fell dead among his horse's feet. The Adelians, disheaitened by their hero's fall, betook themselves to flight; but, meeting with two de- tachments of Amda Sion's ai'my, they were so com- pletely destroyed, that only three out of 5000 are said to have escaped. Nor had the Abyssinians much cause to rejoice in the victory ; for many of their principal officers were slain, and scarcely one of their horsemen left the field without a wound. During the remainder of the campaign, the Abyssi- nians were engaged in destroying the towns and vil- lages, and laying waste the country of tlie Mahome- tans; exercising against these unhappy people every species of cruelty, on pretence of retaliating their inju- ries against the Christians. Weary at length of con- quest and bloodshed, the king returned in triumph to Tegulut, where he died a natural death, after a reign of thirty years ; during which, though almost constantly engaged in war, he never sustained a defeat. The reign of Saif Araad, the son and successor of Amda Sion, is distinguished by ro remarkable transac- tion, except his relieving the Cc;;tic patriarch, whom the soldan of Egypt had thrown into prison. Theodorus, who occupied the throne from the year 1409 to 1412, was the first who retracted the grant of one-third of the kingdom, which Icon Amlac had made to the Abuna. Notwithstanding this infringement, how- ever, on the power of the church, he was so revered by his subjects, for the sanctity of his character, that it is 54 ABYSSINIA. still a prevailing opinion in Abyssinia, that he is to rise again li-om the grave, and reign in his ancicnl kingdom lor a thousand years ; during which pcrioa tlie arms ol the warrior arc to be hung up in the liall, and joy and peace are imiversaily to prevad. Nothing important occurs in the liistoryof Abyssinia, from the death of Theoaorus in 1412, tiUZura Jacob as- cended the throne in HSi. The partiality oi his iiistorians has represented this monarch as another Solomon, an exact model of wliat a sovereign snouid be. He was remarkable for his curiosity with regard to the politics, manners, and religion of other countries; and, by his dtsire, an embassy, consisting of priests from the Abys- sinian convent at Jerusalem, was sent to the council of Florence. The Roman pontiff, pleased with an event which seemed to promise the introduction of his spi- ritual sovereignty into the most important kingdom of Africa, ordered a painting to be taken ol' the embassy, which is still to be seen in the Vatican. A convent was obtained for the Abyssinians at Rome, which, though still preserved, is seldom visited by those to whom it is appropriated. A party was henceforth formed m Abys- sinia in favour of the church of Rome ; and, during this reign, began those religious disputes, which rendered the name of Franks, or P'rangi, so odious and danger- ous. This perfect sovereign, this model for future princes, was the first who introduced religious persecution into his dominions. The established religion was that of the Greek church ; but it was corrupted, in many places, by iMahometan, and even Pagan superstitions. Some families, accused of worshipping the cow and the ser- pent, were dragged before this zealous monarch, who immediately sentenced them to death. Their execution was followed by a proclamation, that whoever did not wear on his right hand an amulet, with this inscription, " I renounce the devil for Christ our Lord," should for- feit his property, and be liable, besides, to corporal punishment. This persecution, which soon became general throughout the kingdom, was committed to Amda Sion, the Acab Saat, a person whose affected austerity had procured him the confidence of the king, by whom he was so highly distinguished, that, when he appeared abroad, he was attended by a number of sol- diers, with drums, trumpets, and other ensigns of mili- tary dignity. The cruelty of this odious inquisitor was severely reprimanded in a public assembly, by certain priests from Jerusalem; the persecution was suppress- ed, and the king now turned his thoughts from religion to the civil improvement of his dominions. The opulence of the Moorish states, arising from their extensive trade, was frequently employed in the pur- poses of rebellion. It became necessary, therefore, to inquire into the circumstances and dispositions of the several governors. With this view he divided the em- pire more distinctly, and, on the frontiers of the Maho- metan states, formed several new governments, which he gave to his Christian soldiers, that they might be ready to check the first tendency to revolt. The last transaction which is recorded of this mo- narch, places his character in a very unfavourable light. The queen, impatient to see her son in possession of the throne, had formed the design of obliging Zara Ja- >ob to associate him as his partner in the government. The plot was discovered by her husband, who ordered her to be scourged to death ; and the young prince, who, 'hough free from the guilt of her conspiracy, had ven- tured to perform the usual solemnities at her ^tzvc. was loaded with irons, and banisned to the lop of a mountain. In this si,^uation, he was saved from death only by the interference of the monks ol Debra Kosse and Dcbra Libarios, who pretended to iiave discovered, by prophecies, visions, and {Ireams, that none but lixda, Mariam should succeed his father on liie throne. From the time when the princes of the royal family had been massacred by Judilli, the custom of confining them on a mountain had been disconiinued. But Baeda Mariam was so convinced, by the imprudence of his mother, and his own sufferings, of the necessity of re- viving it, that all his male relations were arrested by his command, and sent prisoners for life to the high mountain of Geshen, on the confines of Begemder and Amhara. Soon after, he undertook an expedition against the Dobas, a barbarous but wealthy race of shepherds, Pagans by religion, who constantly made inroads into his kingdom, and committed the greatest enormities. The king of Adcl had invited these shepherds to send into his dominions their wives, their children, and most valuable effects ; while he himself would cut off the Abys- sinian army from provision. This proposal was made known to Basda Mariam, who, with a large body of horse, took possession of a pass called Fendera, through which they were obliged to march ; and, when they arrived at that place, their whole company was cut to pieces, without distinction of age or sex. After laying waste their comitry, and forcing tliem to renounce their reli- gion, he scut his army against the kingdom of Adcl, where his general obtained a complete victory. But while he himself was hastening towards that country, resolving to reduce it to the lowest state of subjection, he was seized with a sudden illness, which occasioned his death. About this time, the Portuguese were extending their discoveries along the coast of Africa, and had al- ready formed the project of opening a passage to India by doubling the Cape. A plan was likewise concerted for penetrating through the interior of the African con- tinent, that, if the former project should fail, the mer- chandise of the East Indies might be conveyed to Por- tugal by land. The success of such a scheme was ren- dered probable by the report of some monks, who had been seen at Jerusalem and Alexandria, the subjects, as they said, of a Christian prince in Africa, whose domi- nions extended froni the eastern to the western ocean. Of the truth of their reports, the Portuguese navigators had been so strongly assured by Bemoy, a king of die Jaloffs,that Henry, the scientific and enterprising prince, under whose auspices these plans of discovery were conducted, resolved to send ambassadors to this unknown sovereign. Peter de Covillan, and Alphonso de Paiva, were appointed to this important embassy, with direc- tions to explore the sources of the Indian trade, and the principal markets for spices ; and, above all, to ascertain the possibility of reaching the East Indies by sailing round the southern extiemity of Africa. Thus instruct- ed, they proceeded to Alexandria, thence to Cairo, next to Suez, and afterwards to Aden, a rich commercial town beyond the Straits of Babelmandcb. They sailed from this city in separate directions ; Covillan for India, and De Paiva for Suakem. De Paiva soon lost his life ; but Covillan, after visiting Calicut and Goa, recrossed the Indian ocean, inspected the mines of Sofala, and re- turned by Aden to Cairo, where he heard of the death of his companion. At Cairo he w as met by .two Jews with ABYSSINIA. 55 ietters from the king of Abyssinia ; one of whom he sent back wiJi IctUi-s to thiu monarch in return, luid, witli the other, proceeded to tlie island of Ormus, in the Per- sian gulf. Here the Jew leftlimi; and Covillan return- ed to Aden, whence he passed into the Abyssinian domi- nions. On his arrival in that country, he was kindly received by Alexander the reigning prince, and exalted to the most honourable offices in the state ; though, according to Abyssinian policy, he was never allowed to return to Europe. He lound means, however, to convey, from time to time, important intelligence to the king of Por- tugal. He described the several ports in India which he had seen ; the disposition of the princes ; the situation and riches of the miiies of Sofala. He exhorted the king to pursue, with unremitting diligence, the discove- ry of the passage round Africa ; declaring, that the Cape was well known in India, and that the voyage was at- tended with little danger. To these descriptions he added a chart or map, which he had received from a Moor in India, and in which the Cape, and the cities round the coast, were accurately represented. The reign of Alexander was disturbed by frequent rebellions. Called to the throne while a minor, he had displayed, from his earliest years, an ardent desire to make war against the king of Adel ; but that monarch, convinced, by the misfortunes of his predecessors, that he was luiable to cope in the field with such a powerful adversary, endeavoured to gain over a party at the court of Abyssinia. Za-Saluce, the prime minister, with many of the principal nobility, were seduced by his intrigues; and Saluce, being intrusted with the command of great part of the forces, abandoned his master in the heat of an engagement. This treachery seemed only to infuse fresh courage into Alexander, and the few brave troops who remained with him. Engaging in a narrow defile, the king was close pressed by a Moor, who bore the green standard of Mahomet, on whom he turned suddenly, and slew him with his javelin ; then, wresting the colours from him as he fell, with the point of the spear that bore the ensign, he struck the king of Adel's son to the ground ; on which the Moors retreated from the field. He then returned in pursuit of Za-Saluce, who had has- tened, by forced marches, to Amhara, exciting the spi- rit of revolt in the governors of the provinces through which he passed. Two days after his return to the capi- tal, the young monarch fell a victim to the perfidy of his minister. The traitor soon met with the punishment due to his crimes; for, while attempting to excite a re- volt in Amhara, he was attacked by the nobility of that province, and, being deserted by his troops, was taken prisoner withovit resistance : his eyes were puL out ; and, being mounted on an ass, he was carried through Am- hara and Shoa, amidst the curses and derision of the people. On the death of Alexander's infant son, which hap- ■pened seven months after, Naad, his younger brother, was called, by the unanimous voice of the people, to the throne. His wisdom was coaspicuously disp;:iycd in the first act of his reign. He published a prcjciamation, offering a general pardon to all who had been ci;;;aged in the late rebellion ; and prohibiting, under pain of death, any one from upbraiding his noighbour with his fonner disloyalty. On assuming tne govcrnnant, he found himself engaged in a war which djma;'.d'-d his most vigorous exertions. Ms-ffudi, prince of Arar, a iJistrict in the neighbourhood of Adel, a man of a war- like disposition, and an enthusiastic Mahometan, had made a vow to spend forty days every year, during the lime of Lent, in some part oi Abyssinia. The supersti- tion of the people facilitated his progress; for they ob- served that fast so rigidly as to exhaust tlieir strengtli j insomuch that Mafl'udi had continued for thirty years to ravage the country, during that period, without opposir tion, and was now regarded as invincible. Naad com- manded his soldiers to continue their usual manner of living, without regarding the fast; and, when his enemy advanced with his wonted confidence of success, his army- was entirely ditto pieces. Having thus removed the terrors of invasion, Naad employed the remainder of his days in reforming the manners of his subjects; and, after reigning thirteen years, was succeeded by his son David III. then only eleven years of age. Early in this reign, the Turks, with a view of sharing the profits of the trade carried on in Adel by merchants who had fled from their own op- pressions in India, took possession of Zeyla, a small island in the Red Sea, where they erected a customhouse and oppressed and ruined, as usual, the commerce of the adjacent coasts. Both Adel and Abyssinia were thus menaced by a formidable enemy, who was prevented from overwhelming them only by his attempts to obtain possession of India. In this emergency, Helena, the queen-regent, wished to enter into an alliance with the Portuguese; and, by the advice of Peter Covillan, an Armenian merchant named Matthew, with a young Abyssinian, were sent on an embassy for that purpose to the court of Lisbon. The merchant, though raised to the rank of ambassador, could not sustain the dignity of his new character. AtDabul, in the East Indies, he was seized as a spy ; and, though relieved by Albuquerque, viceroy of Goa, he was not allowed to depart for Portugal till 1513, three years after his arrival in India. He was insulted by the shipmasters with whom he sail- ed for that country; but, on his arrival at Lisbon, he was received with every mark of respect: the shipmasters were loaded with irons, and would probably have died in prison, had not Matthew interceded in their behalf The Prince of Arar, having recovered from the de- feat which he iiaa suffered from Naaa, and increased his power by alliances with the Turks in Arabia, had renewed his annual incursions into Abyssinia with great- er success than before. In return for the multitude of slaves which he had sent to Mecca, he was made sheyhk of Zeyla, which maybe considered the key to the Abys- sinian dominions ; and the king of Adel had been indu- ced, by his success, to enter into a league with him against that empire, which he had always regarded with a very unfriendly eye. Accordingly, they invaded Abys- sinia with their united forces, and committed such devas- tation as spread terror through the whole country. To revenge these injuries, David, then a youth of sixteen, levied a powerful army, by a judicious disposition of which, he hemmed in the Moors among some narrow defiles, where they could not hazard an engagement witliout certain destruction. To add to their consterna- tion, Mafiudicame to the king of Adel, and assured hiin that his time was now come ; that he had been v/arned long before, by a prophecy, tliat if in this year (1516,) he should encounter the king of Abyssinia in person, he should certainly die. He therefore advised him to retreat, as speedily as possible, over the least difiicult part of the mountain, before the battle should commence. The Adtlian, already dismayed by the situation of his 56 ABYSSINIA. anny,\villinigly rollo\vcci his advice ; and Maffudi,as soon as he supposed his ally beyond the roach oi' danger, sent a tnessage to the Abyssinian camp, challenging any man of quality to fight him in single combat, on condition that the party of the victorious champion should be ac- counted conquerors, and that both armies should imme- diately separate without further bloodshed. A monk, named Gabriel Andreas, instantly accepted the chal- lenge ; and, when the combatants met, Maffudi received from his antagonist such a violent stroke with a two- handed sword, as almost severed his body in two. An- dreas cut off his head ; and, throwing it at the king's feet, exclaimed, " There is the Goliah of the Infi-dcls !" Notwithstanding the terms stipulated before the combat, a general engagement ensued, in which tlie Moors were completely discomfited. On the same day (in the month of July 1516) Zeyla was taken, and its to\i n burnt by the Portuguese fleet, under Lopez Suarez de Alberguiera. On board this fleet was Matthew, the Abyssinian ambassador, who had been treated, during his residence in Portugal, with the highest respect, and the most flattering attention. Splen- did lodgings were assigned him, with a magnificent equipage, and a suitable maintenance ; and, on his re- turn, he was accompanied by an ambassador from the court of Lisbon to the Abyssinian king. This ambassa- dor was Edward Galvan, a man who had filled the most important state departments with great applause, but whose advanced age (for he was now a6) rendered him surely very unfit for a voyage so_ distant and perilous. As might liave been foreseen, he died on the island of Camaran, in the Red Sea, where Suarez had imprudent- ly wintered, in the utmost distress for want of provisions. Suarez was superseded by Lopez de Segueyra, who, sailing first to the island of Goa, returned with a strong fleet to the Red Sea, and landed at Masuah, an island belonging to Abyssinia. At the approach of this fleet the inhabitants fled ; but when it had remained for some days off Masuah without committing hostilities, a Chris- tian and a Moor ventured to come from the continent, who informed Segueyra, that the land opposite to Ma- ■ 8uah was part of Abyssinia ; adding, tliat the uihabitants were Christians, and that the reason why they fled at the appearance of the fleet was their dread of the Turks, who frequently made descents, and ravaged the coast. The adjniral, overjoyed at this intelligence, dismissed them with presents, and was soon after visited by the governor of Arkeeko, who informed him, that seven monks were deputed to wait on him from the monaste- ry of Bisan, about twenty-four miles up the country. These monks, on their aiTival, instantly recognised Matthew, and congratulated him warmly on his return. Lopez had next an interview with the Baharnagash, who informed him that the arrival of the Portuguese had been long expected in consequence of ancient prophecies; and that he himself, and all the officers of the king, were ready to serve him. Mutual presents were ex- changed, and an embassy was prepared by the admiral to be sent to the court. Don Roderigo de Lima, who was appointed ambassador instead of Galvan, who had died, was accompanied by a small company of resolute men, willing to ur^dergo any hardship or danger for the glory of their king, and the honour of their country. Their present jotirney required all their constancy. Be- fore they could reach the king, they had to cross the whole extent of the empire, over rugged mountains, and through woods almost impervious, interwoven with briers and thorns, and infested with innumerable wild beasts. Their reception but ill requited the toils ol their journey. De Lima, instead of gaining an imme- diate audience of the king, was waited upon by an offi- cer, called Hadug Ras, who ordered him to pitch his tent three miks larther from the camp; and it was not till three years aftenvards that he obtained leave to de- part. After that long interval, David determuied to send an embassy to Portugal, and dismissed Roderigo with an Abyssinian monk, nanied Zaga Zaab, whom lit appointed his own ambassador. Meanwhile, the Mahometans v, ere alarmed by this long intei'course between two such distant nations, to both of which they were equally inimical. An alliance was formed between the kuig of Adel, and the Turks in Arabia; and the Adelians thus reinforced, and being trained by their new allies to the use of fire-arms, then unknown to the Abyssinians, defeated David in every engagement, and hunted him, like a wild beast, from place to place. Mahomet, surnamed Gragiie, or Ic/t- /lamlcd, who commanded the Turkish army, sent a mes- sage to the king, exhorting him to desist from fighting against God, to make peace while it was yet in his power, and to give him his daughter in marriage, otherwise he would reduce his kingdom to such a state as to be ca- pable of producing nothing but grass. The spirited monarch, yet unsubdued by his misfortunes, would listen to no terms pix)posed by an infidel and a blasphemer. Frequent encounters succeeded, in which David was constantly worsted ; in one engagement his eldest son was killed; in another his youngest was taken prisoner; and he himself, destitute and forlorn, was forced to wan- der about on foot, skulking among the bushes on the mountains. Struck with admiration of his heroism, and with compassion for his misfortunes, many of liis veteran soldiers sought him out in his retreat, and with these he gained some slight advantages, which served to revive the spirits of himself and his followers. But his enemies were too powerful to be resisted with any probability ot final success, and the king, in this hopeless situation, be- gan to turn his thoughts seriously towards Portugal. John Bermudes, one of Rodcrigo's attendants, who had been detained in Abyssinia, was chosen as ambas- sador to his native monarch, with the additional dignity of Abuna. Bigoted to the Roman catholic religion, he refused to accept of this new office, unless his ordina- tion should be approved by the pope ; — a provision to wlijch, though it virtually submitted the church of Abyssinia to tliat of Rome, David was induced, by the necessity of his aff'airs to comply. On his arrival at Lisbon, Bermudes ordered Zaga Zaab to be put in irons for neglecting the interests of his master ; and repre- sented so strongly the distresses of the Abyssinians, tliat he soon obtained an order for 400 musketeers to be sent to their relief, under Don Garcia de Noronha. He would have sailed along with Don Garcia to accelerate tlie progress of the fleet, but was detained a whole year by sickness, occasioned, he suspected, by poison given him by Zaga Zaab, whom the king had set at liberty. Another delay was occasioned by the death of Don Gar. cia. At length it was resolved that Don Stephen de Gama, who had succeeded to Noronha, should sail to the Arabian gulf, in order to secure some Turkish ves- sels which then lay at Suez. Finding that the vessels had been withdrawn before his arrival, he anchored in the port of Masuah, and sent some boats to Arkeeko for water and provisions j but tliat coast was now in posses- ABYSSINIA. 57 bion of the Moors, who seized Uic goods which he had sent in exchange for the desired supplies, and dismissed the boats without any thing in return. A message was afterwards sent to Don Stephen, importing, that if he would make peace with the king of Adel, who was now master of all Ethiopia, his goods should be restored, and his fleet plentifully supplied with water and provisions of every kind. Don Stephen, aware of the perfidy of this proposal, accepted it with seeming pleasure ; pro- mised to cortie ashore as soon as the festival, which the Mahometans were then celebrating, should be ended, sent more goods, and obtained as much provisions as he required. No sooner were they on board, than he Strictly prohibited all intercourse with the shore, and, selecting 600 of his best men, attacked the town of Ar- keeko, massacred all the people he met with, and sent the head of the governor to the Abyssinian court. A new monarch had ascended the throne of that king- dom. During the wars which David carried on with the Moors, a Mahometan chief, named Vizir Mugdid, had attacked the rock of Gcshen, the state prison of the royal family, and, ascending it without opposition, put all the princes to the sword. The heart of this heroic mo- narch could not stand this disaster, and he died in the same year (1540). His son Claudius, who succeeded him, though then only 18 years of age, possessed all the great qualities necessary in the dreadful exigencies of his kingdom; and, before the arrival of the Portuguese, liad already made considerable progress against his ene- mies. He frustrated a league which they had formed against him in the beginning of his reign ; obliged them to desist from pillage ; defeated them in a general en- gagement; and, having intelligence of a design formed against his life by one of his own governors, decoyed the traitor into an ambush, and slew the greater part of his army. Such was the situation of affairs when Don Stephen de Gama came to the assistance of the Abyssinians. The number of men whom the king of Portugal had al- lotted to this service, ainounted to 450; but the officers were men of the first rank, by whose retinue the army was considerablv increased. A general ardour for this enterprise prevailed in the fleet; and the bay, where they were moored, has received, from the murmurs of those who were detained on board, the name of Bahia dos Agravados — the Bay of the Injured. This small but gallant army set out without delay, under the command of Don Christopher do Gama, youngest brother of the admiral. They were met on their march by the queen, attended by her two sisters, and many others of both sexes ; and, after a mutual ex- change of civilities, the queen returned, escorted by 100 musketeers, whom the general had appointed as her guard. After marching eight days through a very rug- ged country, Don Christopher received from Gragne a very insulting defiance, which he retiirned in a similar tone. A battle was fought, in which the Moor, though greatly superior in horse, got such a convincing speci- men of Portuguese valour, that he did not choose, on that occasion, to venture a second engagement. The Portuguese, owing to the advanced state of the season, had now retired into winter quarters ; while Gragne, having received powerful reinforcements to his army, wished to bring them to action before they should be joined by the king. Hurried away by his natural impetuosity, Don Christopher resolved, in opposition to the remonstrances of his most skilful officers, to venture Vol. I. Part I. an engagement, though at prodigious disadvantage. The superiority of the Portuguese, however, was still so Q-rcat, that they seemed likely to obtain the victory, till tneir general, rashly exposing himself, was wounded in the arm by a musket ball. Confusion and defeat ensued ; and the barbarians, obtaining possession of the camp, began to violate the women, who had all retired into the general's tent. On this, an Abyssinian lady, who had married one of the Portuguese, set fire to some barrels of gunpowder which stood in the tent, and thus perished with the ravishers. Don Christopher, disdaining to fly, was forced into a litter, and carried ofl' the field. At the approach of night, he entered a cave to have his wound dressed, but obstinately refused to proceed farther. Betrayed by a woman whom he loved, he was seized next day by a party of the enemy, and carried in triumph to Gragne, who, after many mutual insults, struck off his head, which was sent to Constantinople, while his body was cut to pieces, and dispersed through Abyssinia. The cruelty of this barbarian proved more detrimental to his cause, than if he had been completely defeated. The Portuguese, exasperated by the loss of their gene- ral, were ready to undergo any danger to revenge his death ; while the Turks, irritated by an action which de- prived them of Don Christopher's ransom, abandoned their leader, and returned to their own country. Gragne, thus deserted, was easily defeated by Claudius; and in a subsequent battle, fought on the lOth of February, 1543, his army was routed, and he himself slain by a Portuguese, named Peter Lyon, who had been Don Christopher's valet dc chambre. Gragne's wife and son, with Nur, the son of Mugdid, who destroyed the royal family, fell into the hands of Claudius ; and happy had it been for that monarch if he had immediately ordered them to execution. Relieved from all fear of external enemies, the atten- tion of Claudius was now occupied by affairs of religion. Bermudes, a turbulent bigot, insisted that the king should embrace the doctrines of the Roman church, and establish that religion throughout his dominions. Clau- dius rejected with indignation such an insolent request, and a violent altercation ensued between the Abunaand the sovereign. Matters would have proceeded to the worst extremities, had not C'laudius been prevented from revenging the insults of the patriarch, by a wish la conciliate the Portuguese, from whose continuance in the country he expected the greatest advantages. Arius Dias, their commander, had been persuaded, by the king's influence, to renounce the Roman catholic reli- gion, and be baptized into that of Abyssinia by the name of Marcus, or Marco ; in consequence of which, he was regarded as a naturalized subject, and honoured with the most distinguished marks of royal favour. The quarrel with Bermudes bccomiug every day more vio- lent, the king deprived him or all authority over the Portuguese ; to whom he intimated, that, as he had ap- pointed Marco his captain-general, he expected they wotild obey him alone during their residence in Abyssi- nia. Indignant at this declaration, which, in fact, sub- jected them to the power which they had come to pro- tect, the Portuguese resolved to die sword in hand, rather than submit to such degrading terms. Claudius, having in vain attempted to force them to compliance, had next recourse to artifice; declared his regret for the violent measures he had used, and his readiness to make any compensation for the wrongs which they might H 58 ABYSSINIA. have sufi'ercd. In the mean time, by ordering his sub- jects to supply them with no provisions, and bribing them with great sums of gold, he found means to weaken them eftectually, by dispersing their leaders into difl'crent parts of the kingdom. The result of this quarrel was, that, without any absolute enmity between the king and the Portuguese, Bermudes was persuaded to with- draw to India ; to which place he at length effected his escape, after skulking for two years, forlorn and despis- ed, in a kingdom where he had aspired to equal power with the sovereign. Claudius had scarcely got rid of this turbulent ec- clesiastic, when a new deputation of priests arrived iu his dominions. The Pope, anxious to establish his power in Abyssinia, had invested Nugnez Barctto, of the new order of Jesuits, with the dignity of patriarch of that country, and sent him to attempt the conversion of Claudius and his subjects. Barctto, on arriving at Goa, was informed, that the Abyssinian monarch was so hostile to the church of Rome, that there was no probability of his being fa- vourably received. The patriarch, therefore, rather than expose his own sacred dignity to the danger of m- sult, thought proper to commission some inferior cler- gymen as ambassadors to the king. Accordingly, Oviedo, bishop of llierapolis, Carneyro, bishop of Nice, with several other dignitaries, arrived on this errand at Masuah, in the year 1538, and met with a more favoura- ble reception than they had reason to expect. But the thoughts of Claudius were then occupied about the more important concern of appointing a successor to his throne. He had no son, and his younger brother had been taken by the Moors, during his father's reign, and imprisoned on a high mountain in Adel. His ransom appeared difhcult, and would perhaps have been found impossible, had not a son of the famous Gragne been at the same time a prisoner in Abyssinia ; by releasing whom, and paying besides four thousand ounces of gold, Claudius at length procured tlie restoration of his brother. Nur, the son of Mugdid, had become passionately enamoured of the widow of Gragne ; but she refused to give hixn her hand, till he should present her with the head of Claudius, the murderer of her former husband. The lover willingly undertook the task, and challenged the Abyssinian monarch while marching towards Adel. Claudius was not of a disposition to decline the combat, though it had been prophesied that he should die in this campaign. His soldiers, more alarmed by the predic- tion, abandoned their monarch in the commencement of tlie battle; v.diile attended by only 18 Portuguese and 30 horsemen of Abyssinia, he fought with the most heroic bravery, till at last he fell, completely covered with wounds. His head was cut off, and brought by Nur to his mistress, who hung it up on a tree before her door, where it remained, for three years. After this fatal engagement, which took place on the 'J2d of March 1559, Menas ascended the throne without opposition. During the greater part of his reign he was engaged in war with his own subjects, who were in- stigated to rebellion by the popish missionaries. The insolence of these ecclesiastics at last provoked the king to banish them to a barren and solitary mountain, inclu- ding in their sentence all the rest of the Europeans ; an insult which they resented so hic:hly, that they im- mediately went over to the rebels. Their united forces were defeated by Menas, 'uit the victory was by no means so decisive as to put an end to the rebellion. Afte. a turbulent reign of four years, Menas was suc- ceeded by his son, Sertza Dcnghel,a boy of 12 years of age. This prince was engaged in almost perpetual conflicts with the Galla, the lalasha, and the Moors, in which he was generally victorious. During his reign the Roman Catholics were unmolested, though such a strong prejudice had been excited against them in the minds both of the king and his subjects, that they never ventured to appear at court, nor were permitted to serve in the army. His last expedition was against some rebels who had begun to excite conmiotions in the province of Damot. A priest, revered for his sanc- tity and skill in divination, had warned him, in vain, not to proceed in this enterprise ; and, when he found the warlike monarch obstinate in his purpose, he only requested him not to eat of the fish of a certain river : this advice also was despised; and Sertza Denghel died in consequence of eating these fish, which were of a poisonous quality. A violent dispute now arose about the succession to the throne. In the first stage of his sickness, the late king had nominated his son Jacob as his successor, though then a boy of only seven years of age ; but as he felt his dissolution approaching, he gave the prefer- • ence to his nephew Za Denghel, w ho had reached the years of manhood, and had already displayed the ac- tivity and talents necessary for governing a turbulent people. This appoijitment gave great offence to the queen, and to ma;iy ol the principal nobility, who had ex- pected to engross, during the minority of Jacob, all the power and prerogatives of the crown. Regardless, therefore, of Sertza Denghel's will, the queen, in con- junction with Kesla Wahad and Ras Athanasius, her sons-m-law, immediately proclaimed the mfant Jacob king, and confined Za Denghel to an island in the lake Tzana. An attempt was made at the same time to seize the person of Socinios, the natural son of Facilidas, who might likewise have pretended a right to the throne ; but alamied by the fate of Za Denghel, Socinios had withdrawn from the power of his enemies ; and Za Denghel himself soon found means to escape, and took refuge among the inaccessible mountains of Gojam, Jacob continued till the age of seventeen a passive tool in the hands of his tutors ; but finding that they still wished to prolong their dominion over him, he took the government into his own hands, and banished one of their number to the kingdom of Narea. By this bold exer- cise of power, he so alarmed and exasperated his tutors, that they immediately entered into a conspiracy to de- pose him, and to raise his rival, Za Denghel, to the throne. So effectually had the latter concealed his re- treat, that he was not discovered without much difficulty. Jacob, finding that his fall was determined, fled from his palace with precipitation ; but, being overtaken on the borders of Samen, he was brought back to the new sovereign, who, with a clemency unusual in Abyssinia, contented himself with banishing him for life to Narea. No sooner was Za Denghel established on the tlirone, than he gave great offence to his subjects by his avowed attachment to the church of Rome. The catholic missionaries were now all dead, and their religion was languishing for want of support, when Peter Paez, a man of prudence and talents, was sent on this mission, and arrived in Abyssinia in the year 1600. Instead of intruding himself immediately into the royal presence, Paez quietly took up his residence at the convent of Fremona, wisely judging, that the ABYSSINIA. 59 most ccrtam method of succeeding in the grand object of his mission, was to recommcncl himself, by his utility and conciliating deportment, to the people whom he had come to convert. With this view, he applied assiduous- ly to the study of the Geez, or learned language of the Abyssiniaus ; and, having soon attained such pro- ficiency as to surpass tlie natives themselves, he opened a school, to which Ponuguese and Abyssinians were admitted promixuously. The rapid progress of his scholars acquired him general applause ; and, four years after his arrival, he was sent lor by the king, who honoured him with the most distinguished attention and regard. Tv/oof his pupils, whom he had brought along with him, vanquished, m a religious dispute, the ablest theologians of the kuigdom ; and Paez himself, after celebrating mass, pronounced a sermon in the Geez language, admired for its eloquence and the purity of its diction. So powerful was the effect which it pro- duced on Za Dengliel, already partial to the church of Rome, that he immediately embraced the catholic re- ligion, issued proclamations forbidding the observance of the Jewish Sabbath, and wrote letters to pope Cle- ment VIII. and Philip III. of Spain, requesting them to send mechanics to instruct his people m the arts, and Jesuits to teach them divinity. The Abyssinians, ever prone to revolt, and less easily converted than their sovereign, were instantly in arms. A traitor, named Za Sclasse, under pretence of religious zeal, prevailed on the Abitna to excommunicate Za Denghel, and absolve his subjects from their allegiance. He then proceeded to Gojam, a province remarkable for its aversion to the catholics, where multitudes of rebels flocked round his standard, eager to vindicate the established religion of their country, against the in- novations of foreigners, and the prejudices of their king. Za Denghel on his part was equally zealous ; and, being naturally fond of war, hastened to meet the rebels with what forces he could raise. His troops, who thought themselves under no obligation of fidelity to an excommunicated monarch, deserted him in great num- bers on his march ; and even those who followed him to the field, left him in the heat of battle, surrounded by his enemies, by whom, after performing prodigies of valour, he was overpowered and slain. However un- popular his attachment to the church of Rome may have rendered this prince while alive, the report of his death, and particularly of the heroism which he displayed in the fatal engagement, excited against the rebels such a general indignation, that they did not venture to name any successor to the vacant throne. Socinios, called also Susnus, and Melee Segued, was already in possession of the empire ; and, advancing rapidly with a mighty army, compelled the Ras Athana- sius to acknowledge him as sovereign, and join him with the forces imder his command. When he made a similar proposal to Za Selasse, that traitor first amu- sed him with an equivocal answer, and then marched against him with his whole army ; while Socinios, hap- pening to fall sick, and being unable to confide in Atha- nasius, withdrew to the mountains of Amhara. Za Selasse opposed Socinios, in the expectation that Jacob would revive his pretensions to the crown, under whom he hoped to enjoy all the privileges of sovereignty. A messenger at length arrived from Jacob's camp, inform- ing Selasse that he was then in Dembea, and promising him the highest honours if he would acknowledge and support his claim. The traitor readily complied ; but happening soon after to he defeated by Socinios, with the loss of the greater part of his army, he was coldly received by Jacob, and inmiediately revolted to his rival. Jacob, who was now joined by Athanasius, pos- sessed an army said to have amounted to thirty times the number of that of Socinios ; but, being drav/n by that experienced general into a disadvantageous situa- tion, his army was defeated with great slaughter, and he himself perished in the field. Socinios, thus established on the throne, showed him- self as much inclined as his predecessor to favour the Portuguese. By intermarriages with the natives, and by training theii- sons to war, they had now increased to a numerous army, formidable for their valour, and their superior military skill. It was therefore the in- terest of the sovereign to attach them as much as pos- sible to his cause ; and, as Socinios well understood that this could only be effected by honouring their priests, and favouring their religion, he invited Peter Paez to court; heard him dispute on the supremacy of the Pope, and the double nature of Christ, and deliver a sermon so eloquent and impressive, that he immedi- ately professed his belief in the doctrmes which the patriarch had so ably illustrated ; enlarged the territory of the Jesuits at Fremona ; and delivered to Paez two letters, one addressed to the Pope, acknowledging his supremacy, the other to the king of Portugal, request- ing a new supply of troops to deliver Abyssinia from the inciu'sions of tlie Galla. Soon after these transactions, the king's attention was called from matters of religion, to a rebellion which had already made considerable progress. As the body of Jacob, who fell in the late engagement, had never been found, an impostor, assuming his name, appeared among the mountains of Habab, pretending to have been so dreadfully wounded in the face, that he kept one side of it constantly covered to conceal its deformity. His story obtained general credit, and multitudes flocked to his standard; but, whether from his incapacity to sup- port the imposture, or his deficiency in the qualifica- tions of a general, they were dispersed on the first ap- pearance of the royal army ; the posts which he had taken were successively stormed, till, driven from place to place, he at last effected his retreat into his native mountains. But the spirit of rebellion, instead of being- quelled by the vigorous activity of the royalists, seemed to have diffused itself throughout the whole province of Tigre ; so that Sela Christos, the governor, who had al- ready dispersed the im.postor's army, found it necessary to acquaint his brother Socinios with the state of affairs, and to recjuest his assistance. Most of the troops had been sent on an expedition against the Shangalla and Gongas ; yet the king set out immediately for Tigre with the scanty force which he could muster on this emergency. Hearing, as he advanced, that a party of Galla had posted themselves on a neighbouring hill, he determined to surround them., and thus cut off their re- treat ; but his cavalry, whom he had sent to reconnoitre their situation, were attacked in passing a deep ravme, and almost entirely destroyed ; while the rest of the ar- my were seized with sucli terror, that they refused to proceed. The Galla, eager to improve their advantage, rushed forward to attack them. Socinios, advancing alone, slew the first that opposed him, and his troops, ashamed of their cowardice, and animated by their monarch's example, fell furiously on the enemy, and obtained a decisive victory. The coun^rfeit Jacob. H 2 60 ABYSSINIA. venturing again to take tlic iicld, was defeated by So- cinios with a much inferior force ; and the Gallu, wlio liad committed dreadful excesses in the southern pro- vinces, were surrounded by the king's army, and com- pletely cut to pieces. The imposLor was soon after assassinated, and found to be no other than a herdsman from the mountains, to which he had always fled for re- fuge, who had covered his face, in reality disfigured by no scar, to conceal his want of resemblance to tlie prince, whose character he had assumed. Scarcely was this rebellion suppressed, when an- other of a more alarming nature was excited by one Melchisedec, who had been a servant of Sertza Deng- hel, and possessed considerable knowledge of military affairs. Sanuda, a brave officer, who had been sent to oppose him, lost the whole of his army in a single en- gagement ; while he himself escaped with difficulty, af- ter receiving many wounds. Socinios, after this dis- aster, sent his brother Emana Christos with a considera- ble army, to reduce this formidable traitor. The well- known valour and abilities of Kmana Christos could not remove the terror which the rebel forces had diffused throughout the coimtry. To sanction his cause, Mel- chisedec had got into his possession a prince of the blood royal, named Arzo, whom he proclaimed king ; after which he boldly advanced to meet the royal army. The combat was obstuiate and bloody ; victory seemed even to declare for the rebels ; till Melchisedec, seeing Emar.a Cliristos pushing furiously to the place where he stood, fled with the utmost precipitation. But his cow- ardice availed him nothing ; for he was soon overtaken by the peasants, and executed, with many of his prin- cipal officers, in the manner due to their crimes. The spirit of rebellion now pervaded the kingdom ; the flames of war were kindled in eveiy quarter ; and atrocities perpetrated on both sides, the recital of which would be alike unprofitable and disgusting. The Gon- gas, the Agows, the Galla, and the Jews, who support- ed the pretensions of another impostor, were succes- sively conquered. Extirpation was the principle on which hostilities werp conducted ; a principle which the king, inflamed with religious zeal, exerted in its utmost severity against the Jews. Few of that unhappy people escaped from the general massacre ; their children were sold into captivity ; and those who were allowed to sur- vive, were scattered throughout the empire, compelled to renounce their religion for Christianity, and, in token of their sincerity, to labour publicly on the day which they had been accustomed to regard with scrupulous veneration. During these commotions, Paez continued to labour with unremitting assiduity for the conversion of the Abyssinians to the catholic faith. No man could have been better qualified for such an undertaking. With extensive learning, he possessed likewise eminent skill in the mechanical arts; and such an intimate acquain- tance with human nature, as enabled him to convert these attainments to the best advantage. He instruct- ed the Abyssinians in the art of building ; and, with incredible labour, erected churches and palaces, which could not fail to be viewed with delight and astonish- ment by these rude barbarians. While his genius was thus revered, his amiable manners conciliated affection; presenting a contrast, too striking to be overlooked, to the ignorance and brutality of his antagonists. His suc- cess was such as he was intilled to expect. Scla Chris- tos, the king's brother, became a zealous catholic ; the piinc'.pal people in the kingdom followed his example ; and wlien Simon, tne Abyssnuan patriarch, was admit- ted, at his own request, to discuss with Paez the doc- trines of their respective churches, in the presence of the knig, the inferiority of the Abuna was so apparent, thatSocniios thought iiunself warranted to make a pub- lic avowal ol his ueliel m the catholic doctrines, for which he liad alieady siiowu a sirong predilection. While the labours oi Paez were thus successful, let- ters arrived from iiie pope and kmg of Spain, exhoiting Socinios to continue hi in to the Roman church, and en- couraging ium wiiii liie assurance, not of any tempoi-al support, but of the fir superior aid of the Holy Spirit. A rciiilorcemeiit of soldiers would have been as accepta- ble ; yet the king, thinking pernaps he had advanced too far to recede, resolved to submit in form to his Holi- ness, and immediately appointed ambassadors to convey this important intelligence to Europe. To this embassy Antonio t'ernandez was chosen by lot ; and taking Fecur Egzie as his companion, he set out in the beginning of March Ifil.". As the provmccs in the neighbourhood of Masuah were then in a state of rebellion, the ambassa- dors were obliged to pass through Narca and the southern provinces to Melinda, whence they might sail for Goa. Their route lay iii the countiy of inhospitable savages, whose natural jealousy of the connexion be- tween the Abyssinians and Europeans was increased by the insinuations of an Abyssinian schismatic, named Manquer, who had followed them for the purpose of re- tarding and persecuting them on their journey. After surmounting various obstacles, which his malice threw in their way, they were imprisoned in the kingdom of Alaba, whose sovereign, being a Moor, was persuaded by Manquer, tliat they intended to overturn the Maho- metan religion. The barbarian threatened them with death ; but, after holding a council, in which Manquer gave his voice for their execution, he resolved to send them back to Abyssinia. Thus ended an embassy, which, had it been allowed to proceed to Europe, would have conveyed to the pope the voluntary submission of an Abyssinian monarch, and contributed more than any other cause to the final establishment of popery in tliat kingdom. His subjects did not view with indifference the apos- tasy of Socinios from the established religion. A danger- ous conspii-acy was formed against his life by Emana Christos, his own brother ; Julius, his son-in-law ; and Kefla Wahud, master of the household. They had agreed to assassinate him in the palace ; but the king, being informed of their design just before their arrival, had the address to prevent it. Sentence of excommuni- cation was pronounced against him by the Abuna ; but, on the menaces of Socinios, it was immediately recall- ed. The vengeance of tlie conspirators was next direct- ed against Sela Christos, who had been invested with the government of Gojam, of which his brother Emana Christos had been deprived, for his adherence to the Alexandrian church. Julius governor of Tigre, first ap- peared in arms, and hastened into Gojam, in hopes to surprise Sela Christos. But the whole scheme was frustrated by the vigilance of the king, who advanced into that provmce before the rebels were informed of his intention, and proceeded without delay to meet the army of Julius. Here he posted himself so judiciously, that his enemy could not force him to an engagement without evident disadvantage. But the temerity of Ju- lius brought the affair to a speedy termination; for, ABYSSINIA (il nishlng witli a few attcnilants into the royal camp, he advanced direclly to the kins,^'s tent, where, being re- cognised by the guards, he and his followers were in- stantly despatched. After the death of their leader, the rebel army fled in all directions, and were pursued by the royalists with prodigious slaughter. Emana Christos had taken refuge on a high mountain in Gojam, ■where he was invested by Af Christos, an experienced general ; and, as the mountain was destitute ot water, his soldiers, to save themselves from perishing with thirst, betrayed him into the hands ol his enemy, while he was preparing to make a vigorous defence. He was capi- tally convicted in a full assembly of judges ; but the king remitted the sentence, and confined him in Am- hara. After suppressing two other rebellions, Socinios, irritated by the opposition he had met with, determined to show, in the most public manner, his attachment to the church of Rome. He therefore issued a proclama- tion, renouncing the Alexandrian creed, and inveighing against the profligacy of the Abyssinian clergy. This proclamation is said to have been suggested by Peter Paez, who died immediately after leaving the palace. The first effect it produced was another rebellion in Anihara, which was quickly suppressed by the activity of Sela Christos. Though the embassy to the pope and king of Spain had been constrained to return, frequent accounts had been transmitted to Europe of the revolution which had taken place in the religious affairs of Abyssinia. A new set of missionaries, therefore, were sent to this countiy, under the direction of the patriarch Alphonzo Mendez, and arrived at Gorgora, where the king then resided, in the beginning of the year 1626. At the first audience, Socinios acknowledged the pope's supremacy ; and soon after took the oath of submission in a manner peculiarly solemn. A sermon, ijiforcing the pope's supremacy, was preached by the patriarch in the Portuguese lan- guage, which is said to have powerfully confirmed the faith of Socinios, and his brother Sela Christos, though they understood not a word of the language in which it was delivered. This discourse was answered in the Amliaric language, equally unintelligible to the mis- sionaries, and the patriarch made a short reply in Por- tuguese. At the conclusion of this edifying discussion, the oath was taken by the emperor on his knees, and by all the princes and nobles in succession. Sela Christos, after perfomning this ceremony, drew his sword, and de- nounced vengeance on those who should fall from their duty ; adding at the same tmie an oath of allegiance to the king, and to Facilidas, the prince royal ; but decla- ring, that if the latter should ever fail to promote and defend the catholic faith, he should be his most irrecon- cileablc enemy. The violent character of Mendez, which was exactly the reverse of that of the excellent Paez, excited a gen- eral and deadly hatred against the Roman catholics. At his instigation, an edict was issued by the king, enjoin- ing all the priests to embrace the catholic religion un- der pain of death ; and the people, under the same pen- alty, to observe Lent and Easter, and all the moveable feasts, according to the regulations of the church of Rome. The Abyssinian clergy were re-ordaincd ; the churches were consecrated anew ; even adults under- went a second time the ceremony of bapti.sm ; circum- cision, polygamy, and divorce, which had been allowed by the Alexandrian church, and always practised in Abyssinia, were now abaolu'xly prohioiied. Nay, to such excesses did the frantic zeal of this ecclesiastic proceed, that he ordered the body of an Abyssinian saint to be ignominiously thrown out of the grave, because it had been buried under the altar of a church, which he supposed to be thereby defiled. In consequence of these outrageous proceedings, the whole empire was in a flame of rebellion ; while its external enemies, taking advantage of the general confusiot*, invaded and ravaged it with impunity. At last the king's army, weary of de- stroying their countrymen for a quarrel which they did not understand, demanded the restoration of the ancient religion ; and Socinios himself, wishing to give repose to his exhausted country, first passed an act of general to- leration, and then formally re-established the Alexan- drian faith, liturgy, and altars for communion. Having thus endeavoured to expiate, or at least to heal the cala- mities which his fanaticism had brought on his sub- jects, and being now worn out with age and infirmity, he resigned his crown to Facilidas his son, and passed the remainder of his days in tranquillity and retirement. Facilidas had no sooner ascended the throne than he showed an inveterate enmity against the catholics, and a decided resolution to exterminate them from his domi- nions. Mendez, and all his brethren, were ordered first to retire to Fremona, and afterwards to quit the country. The refractoiy patriarch, instead of obeying this com- mand, applied to the Baharnagash, then in rebellion, who carried them from Fremona by night, under a strong guard, and lodged them safe in the fortress of Adicotta. The Baharnagash conveyed them from place to place, through hot unwholesome situations, exhausting at once their patience and their strength. On receiving a pre- sent of gold, he allowed them to return to Adicotta ; but Facilidas, having discovered their retreat, endeavoured to prevail with the Baharnagash to deliver them into his hands. Delicacy would not allow him to violate the rights of hospitality, by delivering his guests to their enemy ; but he easily consented, on receiving a proper compensation, to sell them as slaves to the Turks. Two alone remained, in hopes of obtaining the crown of mar- tyrdom ; an honour which Facilidas conferred upon them as soon as he got them into his power. Nor was he con^ tent W'ith the extirpation of the missionaries, but resolv- ed to put to death every person of consequence who re- fused to renounce the Roman catholic religion. His un- cle, Sela Christos, was among the first of his victims, re- solutely adhering to his principles, in spite of all the threats and promises of the king. Yet these persecu- tions did not deter the Europeans from sending another mission into Abyssinia. The miscarriages of the Je- suits were ascribed, not without justice, to their own in- solence and obstinacy ; and it was hoped, that mission- aries, of a more prudent and conciliating character, might yet succeed in the great object of subjugating this country to the tyranny of the Roman pontiff. Six capuchins, of the order of St Francis, set out on this mission with protections from the Grand Signior. Of these, two were murdered by the Galla, while attempt- ing to enter Abyssinia by the way of Magadoxa ; two, who reached the country in safety, were there stoned to death ; and the remaining two, hearing atMasuah of the unhappy fate of their companions, did not venture to pro- ceed. Not long after, three other missionaries made a similar attempt; but, at the command of Facilidas, were murdered by the bashaw of Jlasiiah. Notwithstanding the restoratiou of the ancient religi- (32 ABYSSINIA. on, the spirit of rebellion was not yet subdued. Mel- cha Christos, whom, during the last reign, the Agows had endeavoured to exalt to the throne, still continued in arms ; he defeated an army, which Facilidas command- ed in person; and, pursuing his good fortune, seized the royal palace, and was formally crowned. But he did not long continue to enjoy his elevation ; Facilidas quickly recruited his army, which surrounded and at- tacked the rebels, before they were aware of their ap- proach, defeated them with great slaughter, and slew their leader himself. Another rebellion now broke out in Lasta, where the son of Melcha Christos was set up as king, and the rebels seemed determined not to yield while there was a possibility of resistance. After vari- ous success, their general submitted unconditionally to the king, who bestowed on him large possessions in Be- gemder, with his daughter Theoclea in marriage. Facilidas died in October 1665, and was succeeded by his son Hannes, who, though an enthusiastic Chris- tian, was as hostile to the Roman catholics as his pre- decessor had been. After a reign of five years, spent chiefly in regulating church affairs, and contending with the clergy, he was succeeded by his son Yasous, with the approbation and joy of the whole kingdom. The first transaction of this monarch's reign exhibits his character in a very amiable light. Facilidas, after suppressing a rebellion, headed by his brother Claudius, had banished the princes to the mountain of Wechne, where they continued from that lime to be imprisoned. Here they were visited by Yasous, who found them in a condition of extreme wretchedness. His father, a man of a sordid disposition, had withheld the greater part of their revenue, and the little which he did allow them was embezzled by their keepers ; so that these unhappy princes, without the power of complaining, or of procur- ing redress, were left almost entirely destitute of the means of subsistence. Yasous found them in tatters, and many of them almost naked ; and, deeply affected by the sight, distributed among them a large sum of money for present relief, clothed them in a manner suitable to their rank, and made such arrangements, witli regard to iheir revenue, that it could not in fiUurc be embezzled or misapplied. He then conducted the pi-isoners to the foot of the mountain, leaving them at liberty either to return to their residence on its summit, or to remove to any part of the kingdom. By this extraordinary gene- rosity, he so completely gained their aflections, that they unanimously retiu-ned to their former confinement, nor did one of them ever attempt to disturb the tranquillity of his reign. Though possessed of every great and amiable quality, Yasous was not secure from the turbulence of faction, and the machinations of treason. Rebellions were fre- quent in the beginning of his reign, but were quickly suppressed by his activity and valour. Such indeed were his talents as a general, and his personal prowess, that one of his campaigns is esteemed the most brilliant that is recorded in the annals of Abyssinia. In this reign, the correspondence between Europe and Abyssinia was renewed, and attempts were made to revive the in- terests of the Roman church, by introducing new mis- sionaries into the kingdom. Some Italian Franciscans, who had settled at Cairo, were supplanted by a set of capuchins from Jerusalem ; and on their return to Rome, reported, that a number of catliolics had fled from the persecutions in Abyssinia, into the neighbouring coun- tries of Nubia and Sennaar, where they were so much oppressed by the Mahometans, that, unless immedi- ately relieved, they would be compelled to renounce the religion of Jesus for that of the Arabian prophet. The cause of these injured Christians was eagerly espoused in Italy, and a mission instituted for their relief, at the expense of the pope, which still continues under the name of the Kiliiojiic mi.ision. Tliese missionaries were directed to penetrate, if possible, mto Abyssinia ; and to maintain the catholic faith as far as circumstances would permit, till a more favourable opportunity should occur of converting the whole kingdom. About the same time, Louis XIV. of France concerted an embassy to the king of Abyssinia; and, on his applying to the pope for his consent, his holiness appointed six Jesuits as missionaries to that court, with the superior of the Franciscans to be his legate, a latere, furnishing him with suitable presents for the king and his nobility. The entrance of these missionaries into Abyssinia was facilitated by a dangerous scorbutic disorder, with which Yasous and his sou were then afllicted, and for which they wished to have the advice of an European physician. Maillet, the French consul at Cairo, wish- ing to disappoint the Franciscans, prevailed with Hagi Ali, to whom Yasous had applied, to send a Jesuit, called Charles Poncet, as physician, with father Brevedent as his servant. Brevedent died soon after his arrival in Gondar; but Poncet lived to effect the cure of his royal patient, and, notwithstanding the machinations of the Franciscans, returned in safety to Europe. An ambas- sador to the court of France was appointed by Yasous ; but the violence of Maillet prevented him from proceed- ing. By the influence of the Jesuits, another embassy to Abyssinia was concerted by Louis ; and M. de Roule, vice-consul at Damietta, was appointed ambassador. But this mission was very improperly conducted ; it was resisted by the merchants at Cairo, impeded by the Franciscans, and terminated in the murder of De Roule in the kingdom of Sennaar. Immediately before this event, Yasous had been as- sassinated by his son Tecla Haimanout, who was in- stigated to this parricide by the jealousy of the queen. Tecla Haimanout himself shared the same fate in tlte year 1706, and was succeeded by his uncle Tiffilis or Theophilus, whose first care was to discover and execute the murderers of his predecessor. Tigi, one of these assassins, raised an army of Galla, which committed great ravages, but was soon defeated by Theophilus, with a force greatly inferior. Soon after this victoiy Theophilus was seized with a fever, of which he died in September 1709. After his deatli,the line of Solomon was a second tune set aside, and a stranger, named Ous- tas, was raised to the throne. But, though bis character rendered him in every respect worthy of the kingdom, the people were so much attached to the ancient race of monarchs, that he was soon deposed, and David, son of Yasous, was crowned at Gondar on the 30th of January 1714. David, though a rigid Alexandrian, was so provoked by the dissensions of the Abyssinian clergy, that he sent a body of Pagan Galla to a church where they were as- sembled, who massacred them without distinction. This wanton act of cruelty rendered the king so odious, that he was carried off by poison in 1717. David was suc- ceeded by his brother Bactiffa, who endeavoured to se- cure himself, by destroying all the nobility who had any share in former conspiracies. He died in 1729, and was succeeded by his son Yasous II. ABYSfelNIA, 6S Yasous showed an inclination lo promote the arts of peace, renounced the diversion of hunting, and the ex- peditions against the Shangalla, which were usually con- ducted with great barbarity. But being reproached for his inactivity, in a satire, intitlcd, " The Expedition of Yasous the Little," he invaded the kingdom of Sennaar, without the least provocation, and allowed his soldiers to exercise the most dreadful cruelties. He had not long returned from this ruinous expedition, when he was obliged again to take the field against Suhul Michael, governor of Tigr6. The rebel, unable to cope with his sovereign, in open war, fled to a high mountain for re- fuge ; but all his posts being taken by storm, excepting one, which must'iikewise have been carried by the royal army, he requfcstcd a capitulation; consigned into the hands of Yasous a great quantity of tieasure ; and de- scended with a stone upon his head, (indicating, that he had been guilty of a capital crime,) to submit to the clemency of the king. A promise was reluctantly ex- torted from Yasous to spare his life ; but, as soon as the rebel appeared in his presence, his indignation return- ed, and, retracting his promise, he ordered him to be carried out and executed at his tent door. At the in- tercession of all his officers, the king again pardoned him; but with these remarkable words, that he washed his hands of all the blood which should be shed by Mi- chael, before he effected the destruction of his country, which he had long been meditating. Michael, after con- tinuing some time in prison, was restored to his govern- ment of Tigre; and, by his dutiful behaviour, so gained upon the king, that he was made governor of Enderta and Sire, as well as of Tigre, thus becoming master of one half of Abyssinia. But this mcrease of power did not tempt him to any new rebellion during the reign of Yasous, who died in June 1753, in the twenty-fourth year of his reign. Yasous had espoused a princess of the Galla, whose son Joas now succeeded to the throne. Influenced by his mother, the young king showed an almost exclusive preference to the Galla, who, of all people, were most detested by the Abyssinians, both on account of their barbarity, and of the wars which had always subsisted between the two nations. On the accession of Joas, 1200 Galla horse were sent as the portion of his mother ; and these were followed by a number of private persons, at- tracted by curiosity, or the hope of pref.;rment, who were Imbodied into a troop of infantr)-, under the command of Wooshcka. Their favourable reception induced many others to appear. Two of the king's uncles were sent for, who brought along with them a troop of one thousand horse. These Gallas assumed a sovereign authority over the prince, while his native subjects were to the last degree incensed, at seeing their inveterate enemies thus reigning in the heart of their kingdom. So violent was their resentment, when Joas named his uncle Lubo to the government of Amhara, that, to avoid a civil war, he was obliged to retract the appointment. The whole empire was now divided into two factions ; the one headed by the old queen, mother of Yasous, the other by Joas himself and his Galla relations. Welled de rOul, the prime minister, had hitherto restrained, by his prudent conduct, the fury of the opposite parties ; but, after his death, a scene of violence and confusion ensued, which continued for many years. The imprudence of the king first brought matters to a crisis. Ayo, an old and respectable officer, had late- ly resigned the government of Begemdcr into tiic hands of the queen. His son, Marlam Berea, esteem- ed the most accomplished nobleman in the kingdom, had married Ozoro Esther, daughter of tlic old queen by her second husband; and it was of couise expect- ed, that he should succeed liis father in tiie govern- ment. A quarrel had unfortunately happened between Ayo and Suhul Michael, which continued undecided till Ayo resigned. Rejectuig the decision of judges, whom he thought partial and unjust, Mariam insisted that the king should either determine the affair in per- son, or that it shoidd be referred to the sword; and his firmness was branded by his enemies as disobedience and rebellion. On this account, Joas, deprived him, by proclamation, of the govermnent of Begemder, bestow- ing it on his uncle Bruhle. This appointment was heard with general terror and indignation. As Begemder is a frontier province, bordering on the Galla, it was obvi- ous, that on the accession of Bruhle, it would be over- run by that people, savage beyond all other barbarians. Mariam himself was particularly indignant at the man- ner in which he was deprived of his dignity, and sub jected to a race of pagans, whom he had often compel- led in battle to acknowledge his superiority. He sent a remonstrance to the king, reminduig hhn, that he had sworn, as governor of Begemder, to allow none of the Galla to enter his provmce ; warning him of the dan- ger to which the princes in Wechne would be exposed from the vicinity of these barbarians ; and entreating, that, if he was determined to deprive him of the govern- ment, he would at least bestow it on^an Abyssinian noble- man, in which case he would retii'p and live in pi-ivatc with his filth er. At the same time, he declared, that if the king himself should invade his pi;ovince at the head of an army of Galla, he would retire to its farthest ex- tremity, leaving every kind of provision for his majes- ty's troops. But if an army, conducted by a Galla com- mander, should march towards Begemder, he would en- counter them, on the frontiers, before one of them should drink of the well of Fernay, or advance the length of a pike into the province. To this spirited remonstrance, Joas returned a scoffing answer, announcuig the speedy arrival of Bruhle ; at the same time he created Michael governor of Samen, that, in case there should be occa- sion for him, he might meet with no obstruction in his march to Gondar. jNIariam, provoked by the king's message, replied with equal disdain ; alluding ironical- ly to the name of Bruhle, which, in the Abyssinian lan- guage, signifies a bottle, and telling him, that this Bruhle, if sent into that country, should be broken on the rocks of Begemder. The royal army was instantly put in motion,, but the Abyssinians refused to draw a sword against their coun- trymen ; the Galla, unable to support the shock of Ma- riam's army, were defeated at the well of Fernay ; and though Mariam had given express orders that Bruhle should, if possible, be taken alive, one of his servants pierced him twice with a lance, and stretched him dead on the field. On hearing of this disaster, Joas instantly despatched an express for Michael, and invested him with the dignity of Ras, attended with unlimited power, both military and civil. Michael, who was prepared for tliis event, set out foi- the capital with an army of 20,000 cho- sen men, 1000 of whom were armed with muskets. These troops, who were allowed to take along with them neitlier tents nor provisions, desolated the country through which they passed ; so that the inhabitants fled before them, as from the most inveterate enemies. When he 64 ABYSSINIA. arrived at Gondar, Midiael, as if he meant to invest it, took, possession of all the avenues; but, instead ofconi- niittingany act of hostility, he waited on the king witli tlie utmost respect, and, proceeding from the palace to his own house, he there sat in judgment, as the nature of his oflice required. In the administration of justice he was so rigorous and impartial, that in a short time, the most valuable articles were left in the streets of Gondar night and day, without being stolen , and the people, who were at first alarmed by his severity, now only regretted that he had not come sooner to relieve them from the con- fusion and anarchy which had so long prevailed. Having thus secured the tranquillity of the capital, he set out on his expedition to Begemder. But being imwilling to incur the odium which would attend the des- truction of the excellent Mariani, he insisted that the king himself should march from Gondar, attended by his whole army, and took every occasion of extolling Mariam's vir- tues, and censuring the king for attempting to destroy such a meritorious subject. Mariam, as he had pro- mised in his last remonstrance, retired to the extremity of the province, while Joas and Michael hurried on with im- petuosity, spreading terror and desolation wherever they appeared. An engagement took place on the extreme borders of Begemder, in which the royal army, amoun- ting to twice the number of Mariam's, soon obtauied the victory. The unfortunate nobleman, with twelve of his officers, took refuge among the Galla, by whom they were immediately betrayed The throat of Mariam was cut by Lubo, the brother of Bruhic, and his body disfigured in a shocking manner. His head was carried to Michael's tent who would not allow it to be uncovered in his presence ; and when Lubo demanded the twelve officers, who had sought protection from the Ras, to be delivered up for ex- ecution, Michael was so enraged, that he ordered Woo- sheka, Lubo's messenger, to be cut in pieces at his tent- door; an order which would certainly have been execu- ted, had he not fled with the utmost precipitation. Michael had always been offended at the ascendency which the Galla had gained over the king ; and his jealousy was now still farther roused by the favour which Joas dis- played towards another officer, Waragna Fasil, a Galla by birth, who had distinguished himselfat the battle in which Mariam was slain. Not far from the field of battle, Mari- am Barca had a house, where his widow Ozoro Esther at that time resided. Here Fasil, invited by the pleasantness of the situation, encamped with his cavaliy. Ozoro Esther was alarmed. At the advice of Ayto Aylo, a nobleman in whom she placed great confidence, she repaired to Mi- chael's tent, and threw herself at his feet ; while Aylo in- formed the Ras, that she intended to give him her hand, as he was the only person free from the guilt of the mur- der of her fonner husband, who could now afford her pro- tection. Michael, overjoyed at the prospect of such an advantageous match, caused his army to be drawn out in battle-array ; and, sending for a priest, was married to the princess in sight of all the soldiers. The air rung with their acclamations, and Joas, being informed of the reason, ex- pressed his displeasure in such unequivocal terms, that, from Uiat moment, Michael and he regarded each other w ith miuual hatred. A trifling accident soon made their hatred public. Michael, to screen himself from the heat of the sun, happened one day to throw a white handker- chief over his head. The king, who was then marching at the head of his army, regarded this as an insult offered to himself ; and, though the handkerchief was instantly withdrawn, ^youkl accept of no atonement for sucli a hei- nous transgression. Some time after tnis, Fasil Ijcing in- volved hi a quarrel w ith a man of great consequence, the Ras, as civil judge, summoned both parties to appear bc- tcirc his tribunal. Fasil rejected his jurisdiction; and the affair was submitted to the other civil judges, who decided in favour of Michael, and declared Fasil hi re- bellion. This decision was followed by a proclamation, depriving him of his government of Danjot, and of eveiy other public office with which he was Invested. The Galla chief, instead of submitting to this disgrace, en- camjjed on tlie high road betwixt Damot and Gondar, intercepting all the provisions comuig to the capital from the south. A shot was next fired at the Ras from the windows of the palace, while he sat. in judgment in his own house. Tli<^ iufi-ntion of this shot could not be mistaken. Joas instantly removed to a distance, but sent Woosheka to desire Michael to return to Tigre without seeing his face; informing him at the same time, that he had committed to his uncle Lubo the go- vernment of Begemder and Amhara. Next day, four judges were sent to Michael by the king, commanding him, on pain of his severest displeasure, to depart for Tigre with all expedition. The Ras returned a formal answer, expressing his hope that the king himself would immediately march against Fasil. When this was re- fused, Michael issued a proclamation, commanding all the Galla to leave the capital next day on pain of death. Fasil was soon after defeated in an engagement, and obliged to retire into Damot. In this engagement some of the king's black horse were taken, and, on being questioned by Michael, confessed that they had been sent by his majesty to the assistance of his enemy. Mi- chael immediately sent assassins to take away the life of his sovereign, — in which they soon succeeded, and bu- ried him in the church of St Raphael. Michael now placed on the throne Hannes, brother to the late king Bacufla, an old man, who had spent all his days on the mountain of Wechne, and was of course totally unacquainted with political affairs. Hannes had been maimed by the loss of one hand, to prevent him from aspiring to the throne ; for, by the law of Abyssinia, the king must be free from every personal defect. Mi- chael laughed at this objection ; but, on finding him to- tally averse to business, he carried him off by poison, and made his son, Tecla Haimanout, his successor on the throne. He now marched against Fasil without de- lay, and defeated him after an obstinate engagement. Woosheka was taken prisoner, and at the desire (as has been alleged) of Ozoro Esther, that unhappy man was flayed alive, and his skin was formed into a bottle. On the night when the horrid operation was perfomied, the princess appeared in the royal tent, decked like a bride, and afterwards returned in triumph to Gondar. Soon after this, Mr Bruce entered Abyssinia. Dur- ing the whole of his residence in that country, war and bloodshed prevailed. Tecla Haimanout still maintained his ground. An usurper, named Socinios, was reduced to the degrading state of a menial in the king's kitchen. Fasil could not be subdued by the skill or activity of Michael, whom fortune seemed now to have forsaken ; an attempt was even made to assassinate him, and on one occasion he was made prisoner by the rebels. Such is an imperfect sketch of the history of Abys- sinia, a countiy sunk in the lowest state of barbarity, and afflicted — even without the hope of improvement — with all the calamities which result from an ill constitu- ted government. Yet Abyssinia, in extent, m situation. ABY ACA and natural advantages, is the most important country in Africa ; and from tliis kingdom, more conveniently than from any other quarter, might the blessings of civi- lization be diffused through that unfortunate continent. May not the benevolent heart now anticipate, witli con- fidence, the auspicious, and perhaps not far distant era, when the enlightened exertionsot the African Institu- tion shall reclaim from their native indolence and fero- city, the savage inhabitants of this wide portion of the globe, and, by promoting among them the blessings of industry, knowledge, and religion, and teaching them to estimate and improve their local advantages, shall atone, in some degree, for the long train of miseries which they have hitherto suffered from European oppression i ABYSSINIAN Church is the name given to the church established in the empire of Abyssinia. The Abyssinians are said to be a branch of the Copts or Jacobites; though the name of Copt properly applies to those Christians only who dwell in Egypt, Nubia, and tlie adjacent countries. They are called also Mono- fihysites, or Eutychians, because they admit only one nature in Jesus Christ, rejecting the council of Chalce- don. Christianity was introduced into Abyssinia by Fru- mentius, early in the fourth century ; and, according to Mosheim, the doctrines of the Monopliysitcs found their way into this country about the beginning of the seventh century, or perhaps sooner. At the head of the Abyssinian church is a bishop, or Metropolitan, styled Abuna, who is appointed by the patriarch of Alexandria residing at Cairo ; and, by a law of Abyssinia, must always be a foreigner. As the Abuna is generally ignorant of the language and manners of the country, he is not allowed to interfere in the affairs of government. Next to the Abuna in dignity is the Komos, or Hegumcnos, a kind of arch-presbyter; but the Dcb- taras, a set of chanters, who conduct the sacred music, and assist at all the public offices of the church, stand higher than the Komos in general estimation. The dea- cons form the lowest order of the priesthood. All these orders are allowed to marry ; but the monks, who are very numerous, vow aloud, before their superior, to pre- serve chastity ; adding, however, in a whisper, as you pre- serve it. These monks are divided into two classes ; those of Debra Libanos, and those of St Eustathius. They hav« no convents, but live in separate houses round their church. The superior of the monks of Debra Libanos is the Itchegue ; v/ho, at least in troublesome times, is of much greater consequence than the Abuna. The religion of Abyssinia consists merely of a mot- ley collection of traditions, tenets, and ceremonies, de- rived from the Jewish and Christian churches. In their form of worship, Judaism seems to predominate. The rites of Moses are strictly observed; both sexes un- dergo circumcision ; meats prohibited by the Jewish law are abstained from; brothers marry the wives of their deceased brothers ; women are obliged to observe the legal purifications ; Saturday and Sunday are held sacred as Sabbaths ; and persons under Jewish disquali- fications are prohibited from entering the church. They have festivals and saints innumerable. One day is con- secrated to Balaam's ass ; another to Pontius Pilate and his wife ; to Pilate, because he washed his hands before pronouncing sentence on Christ ; to his lady, because she warned him to have nothing to do with the blood of that just person. The Epiphany is celebrated with peculiar festivity, in commemoration of our Saviour's Vol. I. Part I. baptism. On this occasion they plungr; and sport in rivers ; which has given rise to the erroneous opinion, that they are every year baptized anew. They have four seasons of Lent ; the great Lent commences ten - days earlier than in Europe, and is so rigidly observed, that many abstain at that time even from fish; because St Paul says, there is one kind of flesh of men, and ano thcr of fishes. In legends and miracles they at least equal the church of Rome; and so confounded the Je- suits by the numerous and apparently authenticated ac- counts of the wonders performed by their saints, that these missionaries were obliged to deny that miracles were sufficient to prove the truth of a religion. Images embossed, or in relievo, they abhor, as favouring idola- try ; nevertheless their churches are hung round witli pictures, to which they pay the highest veneration. They argue that the soul is uncreated, because God finished all his works on the sixth day. About the intermediate state of souls they are not entirely agreed ; the most prevailing opinion, however, is, that immediately on their separation from the body, the souls of good men enter into bliss. Their canon of scripture is the same as ours ; but they Regard the Song of Solomon as merely a love poem, composed in honour of Pharaoh's daughter, without any mystical allusion to Christ and the church. Upon the whole, it may be said, that the religion of the Abyssinians is a monstrous heap of superstitions unworthily dignified with the name of Christianity ; giv- ing rise sometimes to disputes and persecution ; but in- capable of producing any salutary effect upon the sen- timents or conduct of its professors, {k) ACACIA, in the Linnsean system, a species of Mi- mosa, belonging to the class of Polygamia, and ordci- Monascia. See Botany. The Chinese employ the flowers of this plant to pro- duce that beautiful and durable yellow which has been so much admired in their different stuffs. The flowers ai-e gently heated, in an earthen vessel, till they become a little dry, and of a yellow colour ; and then water is added, till the flowers are held incorporated together. After this mixture is boiled for some time, it becomes thick and yellow, and is then strained through a piece of coarse silk. The strained liquid is now mixed with alum and calcined oyster shells, finely pulverized ; an ounce of alum, and the same quantity of oyster shells, being added for every three pounds of acacia flov/ers. The different shades of yellow are produced by mixing different quantities of acacia seeds with the flowers; only a little Brazil wood is required for the deepest yel- low. {iv) ACACIA, an astringent gummy substance, being the inspissated juice of tlie unripe pods of the Mimosa Nilotic A of Linnaeus.

Hu- crat. Hist. Kctlcs. lib. 7. cap. 21. (to) ACADEMICS, a name commonly employed to dis- tinguish the disciples of the school of Plato among llie ancient sects cf philosophy. It originated from the circtmistancc of Plato having chosen as the theatre of his insti'uctionsa public grove in the vicinity ol Athens, tailed the Jcademy^ trom Hccademus, who had bequeath- ed it to his fellow-citizens for the purpose of gymnastic exercises. Upon this account, the doctrine of the Pla- tonic school was called the Academical Pliiloaolthy, and those who adopted it, Academics. The peculiar characteristic by which the academical philosophy was distinguished from all other ancient sects, was a certain degree of doubt, or scepticism, concerning the original principles of knowledge. The scepticisniof Plato, however, was much more moderate than that of some of his successors in the academic chair ; insomuch, that the doctrines .of the academy have been distinguished into three successive schools, or eras, each varying from the scepticism of its prede- cessor, and denomhiatcd the Old Academy^ the Middle Academy, and the jYevj Academy. If Plato doubted concerning the truths which are in- titled to implicit admission, it was not in order to damp the ardour of the inquisitive examiner of nature, but to guard against tlie false confidence and precipitate deci- sion, which are so fatal to the progress of true science. He had learned from his master Socrates, the advan- tages which may be derived from putting every thing to the test of close and unprejudiced reasoning. The great prevalence of sophistry in the age in which he lived, convinced him of the lacility with which the mind imposes upon itself, and substitutes the false glosses of its fancy for the pure and immutable, though recondite truths of nature. He, therefore, resolved to distrust the impressions which the ordinary contemplation ol objects excited; and seek after those more secret laws and con- necting causes in the order of things, which escape the penetration of the vulgar; while they constitute the true province and nol)lest pursuit of the philosopher. That Plato ascribed the uncertainty which accompanies the search after truth, not to the nature of things themselves, but to the imperfection of the human faculties, is evident from the foUowiiig passage of his Phxdo : " If we are unable to discover truth, this must be owing to one of two reasons; either that there is no truth in the nature of things themselves, or that the mind of man is, from some i-adical defect, unable to discover it. Upon the latter supposition, the uncertainty of human opinions may be fully accounted for; and therefore we ought to ascribe all our errors to the defectiveness of our own minds, and not to affirm, gratuitously, that there is any defect in the nature of things. Truth is frequently difficult of access ; and therefore to arrive at it, we must proceed with caution and diffidence, examining carefully every step which we take; yet, after all our efforts, we shall often find ourselves disappointed, and forced to sit down, confessing our ignorance and our weakness." True science, according to the sublime conceptions of Plato, ivas conversant, not about those material forms and im- perfect intelligences which we meet with in our daily intercourse with men ; but it investigates the nature of those purer and more perfect patterns, which were the models, or archetypes, after which all created beings were formed. These perfect exemplars he supposes to have existed from all eternity, and he calls them the Idea* of the great original Intelligence. As these caimot be perceived by the human senses, whatever knowledge we derive fi'om that source is unsatisfactory and uncertain. Plato, therefore, must be admitted as maintaining that degree of scepticism which ilenies all paramount autho- rity to the evidence of sense. The tenets of the Academy, as originally promulgated by Plato, were taught in succession by his nephew Speusippus, his disciple Xenocrates, by Polemo, Cran- tor, and Crates ; in whom the series of philosophers of the Old, or proper Academy, terminated. After the death of Crates, which happened about the middle of the third century before Christ, that innovation in the tenets of the school took place, which gave rise to tlic appellation of the Middle Academy. This innovation was made by Arcesilaus of .fiolis ; a philosopher who, after having attended various philosophical schools, finally attached himself to that of Plato. He was of a gay and luxurious disposition, and inclined to treat the contentions of philosophers with more levity than be- came a professed votary of science. He taught that although there may be a real certainty in the nature of things, yet every thing is uncertain to the human under- standing ; and consequently, that all confident assertions arc absiu'd. He admitted, that the testimony of the senses, and the authority of reason, might be sufficient for the ordinary conduct of life ; but denied that they were capable of ascertaining the real nature of things ; — a doctrine reconcileable, without much difficulty, to the assertion of Plato, that every kind of knowledge derived from sensible objects is uncertain ; and that the only true science is that which is employed upon the immu- table objects of intelligence. After the death of Arcesilaus, the academy was suc- cessively under the care of Lacydes, Evander, and Egesinus. Its new tenets, however, meeting with great opposition, these philosophers found it difficult to sup- port the credit of the school ; and Carneades, a Cyrenian by birth, and one of its disciples, found it reasonable to modify what was most obnoxious in the system of Ar- cesilaus, and became the founder of the ^'Vto Academy. It was his doctrine, that the senses, the understanding, and the imagination, frequently deceive us, and there- fore cannot be infallible judges of truth ; but that from the impressions which we perceive to be produced on the mind by means of the senses, we justly infer ap- pearances of truth or probabilities. These impressions Carneades aiWcH phantasies., or images; and maintained, that they do not always correspond to the real nature of thuigs. The successors of Carneades in the New Aca- demy, were Clitomachus, a native of Carthage, Philoof Larissa, and Antiochus of Ascalon, who resigned the chair in the 1 75th Olympiad, when the Academic School was transferred to Rome. The learning and eloquence of Philo are highly celebrated by Cicero, who knew him at Rome, whither he had fled for refuge during the Mlthridatic war. He is reckoned by some the founder of a fourth academy ; as he held the peculiar tenet, that truth in its nature is comprehensible, although not by the human faculties. Thus it appears that scepticism was to a certain ex- tent encouraged by all the teachers of the Academic school, but most of all by Arcesilaus, and his followers of the middle academy ; and in the lowest degree by Plato, and the more genuine Academics. If Plato seemed to contract our sphere of knowledge, it was ACA ACA only with the intention of direcling the strongest illumi- nation on tlie objects wiiicli were most iraught with in- struction, and subservient to the highest purposes. But Arcesilaus, by placing in the same obscurity every ob- ject within the utmost extent of the splK-re, encouraged a chilling and dangerous indiflercnce about every princi- ple, whether of speculation or action. Such, however, were not the genuine doctrines of the Academy, as is frequently assumed by Hume, and other modern free- thinkers, who wish to arrogate to themselves the ho- nourable title of Academics, instead of the more appro- priate, though reproachful, appellation of sceptics. The scepticism of Plato, and his genuine followers, was not that which wishes to throw doubt and obscurity upon every object of human knowledge, but that which hesi- tates to assume what it has not investigated ; and is cau- tious of believing, in order that it may believe nothing that is not absolutely conformable to truth. This rational, or Platonic scepticism, may be seen admirably exempli- fied in some of the philosophical writings of Cicero, who, though he sometimes calls himself an eclectic philoso- pher, and professes to select whatever he found most valuable in the various schools of Greece, shows a mani- fest predilection for the doctrines of the academy as taught by Plato ; and therefore may be considered as a genuine academic.

The term Academy is of the same ori- gin as Academics, though some are of opinion that it was derived from Cadmus, who first brought letters from Phoenicia to Greece, and who introduced into that savage country the learning and mythology of Egypt. It is now employed to denote a society of learned men, associated for the pui'^iose of advancing the arts and sci- ences, by communicating to the world the discoveries which are made either by its own members, or by other learned individuals. The first academy of this kind of which we have any account, is that which Charlemagne established, by the advice of his preceptor Alcuin. It was composed of the learned men of the court, at the head of whom was the emperor himself. The object of this institution was to promote a taste for polite literature, and improve the language of the country, w-hich was at that time in a very rude state. As this oljject could only be attained by a careful study of the compositions of antiqui- ty, it was required of each member to give an account of the ancient authors which he had read, and communi- cate the remarks he had made upon them ; and so great was their attachment to the ancients, that they are said even to have assumed their names. See Alcuin. The exertions of Alcuin were honourable and useful; but they were unable to dispel the darkness of the mid- dle ages. The institution died with himself; and the troubles consequent upon the dissolution of the Carlo- vingian monarchy, extinguished the few faint lights that were beginning to irradiate the gloom. During several successive ages, we find no association for the advance- ment of learning. The prevalence of the feudal system nourished a spirit inconsistent with literary repose. In- dividuals of superior talents now and then appeared, but their discoveries, from the unfavourable circumstances of the times, perished with themselves. The little know- ledge that survived the general wreck, ivas preserved in the cells of the monks, for the benefit of future ages. Every attempt at improvement in Europe had been partial and unsuccessful, till the final overthrow of the Roman empire by the 'I'urks, in 1453. At that time seve- ral Greek scholars, driven from their habitations, came and settled in Italy, where they established schools, which formed the basis of the numerous academical in- stitutions that sviccessively arose in the surrounding countries. In giving an account of these institutions, we shall begin with Italy, and then proceed to the other countries in which academies have been established. Italian Academies. In Italy the ninnber of aca- demical institutions increased with such rapidity, that they are said to have amounted in a short time to 550. In the city of Milan alone, Jarckius reckons 25, of which he has given the history. The names of many of the Italian academies arc curious and expressive: Thus wc find the academy of the .'Ihbandonuli, .icerbi, Afflati, Af- fettuosi, Acuti, Agitati, J.iinatici, Insipidi, Onibrosi, Fv- mosi, Incjuieti, and above an hundred others of a similar kind, an account of which will be found in Alazzuchelli'n Scrittori D'ltalia. Instead therefore of attempting to give a particular account of all the Italian academies, wc shall confine our attention to some of the most re- markable. So early as the year 1345, an association was formed by the painters of Venice, imder the protection of St Luke, for the improvement of their own art. Another of the same kmd, called the society of St Luke, was established at Florence in 135(i, under the particular patronage ot the house of Medici. These early insti- tutions, though they had not then obtained the name of academies, were yet the same in their nature, and served as a model for many other academical institutions, which afterwards arose in different parts of the continent. In the I5th century, an academy had been established at Naples, in the reign of Alphonso I. by Antonio Bec- catelli, and several other eminent men, whom that patron of letters had attracted to his court. After the death of Beccatelli, the charge of the academy devolved upon Pon- tano, under whose direction it rose to a considerable degree of respectability. It not only contained the chief literati at Naples, but had associated to itself for honora- ry members, the most eminent scholars in other parts of Europe. The place where it met was dcnom.inated the Portico. We are informed by Apostolo Zeno,that Ber- nardo Christoforo, a learned Neapolitan, had written the history of this early institution, in a work intitled, .4cade- mia Pontani; give Vita illustriitm virorum, qui cum Jo. Joz'iano Pontano, J\''eafioH floruere : But the manuscript is now lost. See Roscoe's Life of Leo X. A new academy was established at Naples in 178", un- der the title of Reali Acadcmia delle Scirnze et Belle Lettere di Kalioli. The first volume of their Transac- tions was published at Naples in 1788. in 4to. In the 15th century, under the pontificate of Paul II. an attempt was made to establish in Rome an academy for the study of antiquities : but the jealousy of that haughty and ignorant pontiff defeated the plan by doom- ing to imprisonment and death, some of the most emi- nent scholars of that time. Under the auspices of Leo X. the plan was carried into execution, and the acade- my continued long in a flourishing state. It, however, fell gradually into decay, but gave birth to others of greater celebrity. I 2 tin ACADExMY. About the lakldlc of the lollowing century, an acade- my was established at Rossano, in the kingdom of Na- ples, called La Hocieta Hciemifica Jiomune/ise Dei;l' In- curiosi. ^ About the year 1560, an academy was formed at Na- ples, in the house of Baptista Porta, called, Acadcmia Se- rretontm J\l'atiirx, which had for its object the investiga- tion of physical science. Its founder having recently returned from his travels, communicated the informa- tion which he had collected to his fellow-members, who, in their turn, imparted the knowledge which they had individuallv obtained. The church of Rome, how- ever, becoming jealous of this flourishing association, put an end to its meetings, lest the diflusion of know- ledge should undermine the foundation of the Catholic faith. The Academy of Secrets was succeeded by the Aca- demia Li/ncei, established at Rome in the beginning of the 17th century, by prince Frederick Cesi, for the ad- vancement of physical science. It was composed of the roost eminent philosophers of the age, among whom was the illustrious Galileo. About the close of the same century, another academy was formed at Rome, for reviving the study of poetry and belles lettres. It was named Jrcadi, from a regu- lation that required all the members to appear masked like shepherds of Arcadia. Ladies were admitted to this academy, and in the space of ten years its mem- bers amounted to the number of 600. They held their meetings seven times a-year in a meadow or grove, or in the garden of some nobleman of distinction. All the members of the academy assiuned, at their admission, new pastoral names, in imitation of the ancient Arcadians. There were diflfcrent branches of this institution through- out Italy, which were regulated after the same manner. About the middle of the 1 6th century, an academy was instituted at Umidi in Florence, in honour of the grand duke Cosmo I. who, in 1549, declared himself its protector. It was afterwards called Academia la Flo- rentina, and goes under the name of the Florentine Aca- demy. Its chief attention was directed to the Italian poetry. It has produced many excellent works, and for these two last centuries has included most of the eminent characters in Italy. The Acadcmia delta Crusca, or Academia Furfurato- rum, the Bran Academy, was so named probably from the nature of its institution, the design of which was to polish and improve the Italian language, to sift the words, as it were, and reject all such as were barbarous, or of doubtful authority. It was formed in 1582, but was lit- tle known till two years after, when it attracted notice on account of a dispute between Tasso and some of its members. The chief work which it has produced, is an Italian Dictionai-y, a well known work of great merit. In this academy, Toricelli, the disciple of Galileo, de- livered many of his philosophical discourses. It is now united with two others, viz. the Fiorenlina and A/iatista, under the name of the Reali Acadcmia Fiorentina. The Academia della Crusca was followed by another academy at Florence, under the name of Del Cimento. It arose towards the beginning of the 17th century, un- der the protection of prince Leopold, afterwards Cardi- nal de Medicis; and numbered among its members Paul del Buono, who, in 1657, invented an instrument to prove the incompressibility of water; Alphonso Bo- relli, celebrated for his book dr Motu Animalium ; count Lawrence Magalotti, who, in 1677, ptiblished % book of curious experiments, under the title of Saffffi di Natu- ral Fsfiericnzc, a copy of which being presented to the Royal Society of LonUon, was translated uito English by Mr Waller, and published in 4lo, in 1684;— together with other philosophers of equal reputation. Academia /Jorionicnsi/), was founded at Bologna, by Eustachio Manfredi, in 1690. At the early age of six- teen, this young man associated to himself some of his companions, with the view of discussing those subjects, to which, in the course of their studies, their attention was directed. They held stated meetings in the apart- ment of Manfredi, and appointed beioiehand the sub- jects that were to be discussed. Their armorial badge was the planetary system, surrounded by a serpent hold- ing its tail hi its mouth; and their motto. Mom Ajfitae ; from which they assumed the name of Intjuicti. The members of this academy gradually increased, and many of them attained the highest literary and scientific ho- nours. In 1704, J. B. Morgagni being made director, new-modelled the academy, with the assistance of E. Manfredi and Stancarius ; banished, in a great measure, the useless speculations of the schoolmen; and introdu- ced the mode of philosophizing, which has been since followed with so much success. In 1714, this academy was united with the Bononian Institute, which was a kind of college under the protection of the senate, and richly endowed by Clement XI. and Benedict XIV. as well as by the liberality of private individuals. Hence it obtain- ed tlie name of the Academy of the Insritute, and the di- rector was named president. Not only were persons of both sexes admitted members of this academy, but seve- ral ladies were raised to professorships. Of these, Anna Manzolini was professor of anatomy ; and Laura Bassi, who died in 1778, was renowned for her knowledge of the abstruse sciences. "The place in which the acade- my met," says count Stolberg, " is an enormous build- ing, which contains above forty apartments, with many halls under them. The learned have assured me, that the cabinet of natural history is not only amply provided with the wealth of nature, in every division of her three kingdoms, but the specimens, especially the fossils, are peculiarly fine. The library is said to contain above 120,000 volumes, not including the numerous and valua- ble manuscripts which fill a whole apartment ; and the separate apartments that are allotted for study, are fur- nished with an individual library for each science. The celebrated hall of anatomy is large, and well supplied with waxen models of all the parts of the human body. The large and valuable collection of philosophical instru- ments, which belonged to the late lord Cowper, was purchased by some private citizens of Bologna, and pre- sented to the institution." See Stolberg's Travels, vol. i. p. 265, 4to. The Commentarii Bononienses were se- lected from the early productions of the institution ; and the first volume appeared at Bologna in the year 1748, to which is prefixed an account of the nature and early history of the academy. Since that time, a considera- ble number of volumes have been published. There was also an academy instituted at Bologna in 1687; the object of which was to examine the doctrine, discipline, and history of the church. A Cosmographical Academy was founded at Venice, by Vincent Coronelli, about the beginning of the 18th cen- tury, for the extension of geographical knowledge. The device of the academy was the terraqueous globe, with the motioplus ultra. The members took the title of Arge:naut'f, All the globes, maps, and geographical ACADEMY. 69 writings of Coronelli, have beeu published at the expense of the aciiclcmy. The tioi/al Jlcaclcmy of Siitnces at Tur'm., was insti- tuted about the middle of the 18lh century. It began to publish its memoirs in 1759, in 4to, under the title of Miscellunia Fhilusofihko-Mathematka Hocictatis /irivatx Taurinennis, znd was honoured with several papers by the illustrious La Gra\ige. In consequence of the annexa- tion of Turin to France, this academy was new modelled, and received tlie name of the Im/ierial Academy of Scie?ices, Literature and the Fine Arts., at Turin. Two 4to vols, of its memoirs have been published for 1 804 and 1805 ; one of which contains papers on literature and the fine arts ; and the other, a history of the academy, by the secretary VopaliEandi. The Academy of Sciences at Siena, instituted by prince Leopold in 1767, published their transactions in a con- siderable number of volumes ; of which the first ap- peared m 1771, and the 7th in 1794, in 4to, under the title of Atti dell' Academia di Siena. The Academy of Padua, was established towards the end of the 18th century; and in 1794, had published three volumes of their ti'ansactions, under the title of Saggi Scienlifica e Literari dell ' Academia di Padova.

Having taken a general view of some of the most celebrated Italian academies, we shall now give an account of the academical institutions in France. The first of these that claims our notice is the Academic Pranpise, or the French Academy, which was established by Cardinal Richelieu in 1635, for the purpose chiefly of improving tlie French language, though its plan also comprehended grammar, poetry, and eloquence. This academy has produced many ex- cellent works ; but it is chiefly celebrated for its dic- tionary of the French tongue, which, after a labour of about 50 years, was published in 1694. It has gone through several editions, and the academy, till its aboli- tion by the Convention, was employed in improving it. The histoiy of the academy, to the year 1692, is written by M. Pelisson, and continued to the year 1706 by M. I'Abbfe d'Olivet. The French Academy was followed by that of Paint- ing and Sculfiture. So far back as the end of the 14th century, we find an institution established at Paris, under the title of the Academy of St Luke. In 1430, Charles VII. conferred upon it many privileges, which were confirmed by Henry III. in 1584. It was afterwards united with the Society of Sculptors, who had a house near St Denys, where they held their meetings, and dis- tributed their annual prizes. This institution had fallen into decay, till it was revived by Le Brun, Sarazin, Cor- neille, and some other eminent painters and sculptors, ■who are generally considered as its founders. There were twelve professors, each of whom attended a month in the year, and in case of absence, their place was sup- plied by twelve adjuncts. The academists drew after the model of a naked man, whom the attending professor set in two different attitudes every week. This was called, setting the model. In one of the weeks of the month he placed two models together, which was called, setting the grouft. The paintings and models formed after this standard, were called Academics, or Academy Figures. They had likewise a naked woman, who stood for a model in the public school. Three prizes for de- sign were distributed among the scholars every three months : two for painting, and two for sculpture, every year. An account of this academy has been published by Guerin, under the title of Descri/ition de I' Academic lioyule de Peinture et de Scul/Uure. While France, from the time of Henry IV. had been rapidly advancing in opulence and power, it was also making great progress in science and learning. Two great literary institutions had already been formed, the labours of which contributed greatly to animate the French to new exertions. This appeared in the forma- tion of an academy at Paris by M. Colbert, in 1663, under the patronage of the king ; the object of which was to study and explain ancient monuments, and to preserve the memory of important events, particularly those of the French monarchy, by coins, inscriptions, relievos, &c. It consisted at first of only four members, Messrs Charpentier, Quinalt, I'Abbe Tallemant, and Felibien, who were chosen from the Academie Frangoise, and met in the library of M. Colbert. From the small num- ber of its members, it was at first named Petite Academie ; but about the year 1691, it began to obtain the name of Academie Royale des Inscri/itions et Medailles. The academy first directed their attention to devices for the hangings of the palace at Versailles, and for ships, buildings, &c. They then proceeded to give plans of the king's conquests, with views and descrip- tions of the cities and principal places. At last they lut- dertook a medallic history of the king's reign, which, after several interruptions, was brought down to the ac- cession of the duke of Anjou to the crown of Spain. In this history, the establishment of the academy itself was not forgotten. One of the medals represents Mer- cury sitting, and writing with an ancient stylus upon a brass table. His left hand is supported upon an urn full of medals, and at his feet there are several other medals placed upon a card. The legend, Rerum gestarum fides, and the exergue, Academia Regia inscri/itionum et vumismatum instituta M.DC.LXIII. signifies that the Royal Academy of Inscriptions and Medals ought to give to future ages a faithful testimony of great actions. The memoirs of the academy are published in a great number of volumes, in which the eloges of the mem- bers are written by the secretary. Their motto is^ Vetat mori. The academies at Paris already mentioned were in a great measure eclipsed by the Royal Academy of Sci- ences which was established in 1666, by Louis XIV. When the peace of t!ie Pyrenees allowed this monarch to rest from his conquests, he instructed his minister Colbert, to form a society of men distinguished for their learning and talents, who should meet under the royal protection, and commimicate their respective disco- veries. Agreeably to these instructions, Colbert se- lected some of those who were most celebrated for their knowledge in physics, mathematics, history, and the belles lettres, to form the new institution. The members were arranged into four distinct classes, and had tlieir meetings appointed on different days. But the classes of history and belles lettres were afterwards taken from it, and united to the French academy ; so that there remain- ed only the classes of mathematics and natural philoso- phy. At this early period, the academy published, in 70 ACADE^IY. 1692-3, some fugitive piec.es, which had been read in the meetings of these years, but which were too short for separate publication ; and many of the academicians re- ceived considerable pensions from the king. In 1699, at the suijgestion of the Abbe Cignon, who had long been president, it obtained a new set of regula- tions ; according to which its members were divided into honorary, pensionaries, or those who received sala- ries from the king, associates, and cleves. In 17 16, the duke of Orleans, with the authority of the king, suppressed the class of elevcs, and established in its place 12 adjuncts, to whom he gave the power of voting in matters of science. The number of honorary members was increased to 12 ; and a class of associates was created to the number of six, who were not confined to any particular department of science. It underwent still farther changes in the year 1785. The king added classes of natural history, agriculture, mineralogy, and physics, and incorporated the associates and adjuncts, limiting the members of each class to six. These classes were composed of persons celebrated for their literary and scientific attainments. There were besides a perpetual secretary and treasurer ; twelve free asso- ciates, and eight associate foreigners. This academy has done more to promote the progress of science, than any other upon the continent. It has repeatedly sent otit persons to make observations in different parts of the world, and has been at great pains in computing the meridian. Since the re-establishment of the academy, in 1699, it has annually published a cjuarlo volume, containing the papers that have been read in it during that year. A history of the academy, together with an epitome of its memoirs, has been pre- fixed to each volume ; and at the end of the history are eulogiums on such academists as have died in the course of the year. The Abbe Rozier has published, in four 4to volumes, an excellent index to the whole, from its commencement to the year 1770. M. Rouille de Meslay, founded two prizes, one of 2500, and the other of 2000 livres, to be distributed every year alternately. The subject of the first related to physical astronomy ; that of the latter, to navigation and commerce. Besides these prizes, and the salaries which were regularly paid to the pensionaries, extraordinary gratuities were sometimes given, and sucli expenses defrayed as were necessarily incurred in making experiments. The memoirs of the academy, from its commence- ment till the year 1793, when it was abolished by the Convention, are comprehended in 139 volumes, in 4to ; 11 from its foundation to its re-establishment in 1699 ; 92 from 1699 to 1790; the year 1772 containing two volumes ; 1 1 of memoirs presented to the academy by learned foreigners ; nine of prizes ; nine of tables to 1780; and seven of drawings of machines. The history of the academy, to the year 1697, was written by Duhamel, and continued from year to year by Fontenelle, under the following titles ; Dvliarnel Histo- ria Re,^iie ylcadeiriiix Scientiarum.

Their motto is Invenit el fierfecit. This academy having been abolished at tlie Revolution, a new one was established in its place under the name of the J^'aiional Institute ; for an account of which, see Institute. ■ The Royal Academy of Surgery was instituted at Paris in 1731, and confirmed by letters patent in 1748. The object ot this institution is not merely to conmiunicate the observations and discoveries of its members, but also to give an account of whatever is written on surgery. All the regular surgeons in Paris are members of this academy. Forty members are coimsellors of a perpe- tual committee, and there arc twenty adjuncts. A ques- tion is proposed yearly, and a gold medal of the value of 300 livres is given to him who can produce the best answer. Their transactions have been published in a considerable number of volumes. Besides these, the French have many other academies of less note ; viz. The Academic des jcux Floratix, esta- blished at Thoulouse, consisting of 40 members, and one of the most ancient m tlie kingdom. The Royal Academy of Sciences and Polite I^ittrature at Thoulouse, whose transactions have been published in a considerable num- ber of volumes, the first of which appeared in 1782, in 4to. The academy at Caen, founded by letters patent, in 1705. The academy at Rouen, established in 1736, by M. Le Cat, who was its perpetual secretary. There were also academies founded at Bourdeaux, 1703 ; Sois- sons, 1675 ; Marseilles, 1726 ; Dijon, Orleans, Pan, Be- zigrs, Montauban, Metz, Amiens, 1750 ; Chalons, Naiici, &c. At Dijon, there is a very handsome saloon, belong- ing to the academy, ornamented with the busts of the eminent men whom that city has produced. Among these are Bossuet, Fevret, De Brosses, Crebillon, Pyron, and Buffon. German Academies. The establishment of acade- mies in Italy, France, and England, animated the Ger- mans to establish institutions of a similar kind. The works of lord Bacon, in particular, inspired the nations of Europe with new ardour hi the prosecution of sci- ence ; and to them, chiefly, Bucknerus ascribes the in- stitution of the Academia J^'a'urx Curiosorum. This academy was first begun by M. Bausch, a celebrated phvsicianin Swinfurth, a city in the circle of Fi'anconia. Having associated with himself some other physicians, he drew up a set of rules, which constituted the founda- tion of this new institution, the object of which was the communication of new and important physical discove- ries. Their first meeting was held on January 1, 1652, when Bausch was elected president, and, at the same meeting, two adjuncts were chosen, whose office it was toassistthe president. Every six months the president proposed to each of the members a subject connected with zoology, botany, or mineralogy ; and the memoirs, which were written on these subjects, were published in a detached form. In 1670, they resolved to publish a volume annually; and the first volume, which consisted of pieces printed at different times, appeared at Leipsic, in 1684, under the title of H/ihemerides, which was followed by other volumes, with some interruptions, and variations of the title. In 1 687, the academy was taken under the pro- tection of the emperor Leopold, who conferred upon it several privileges, and raised its students to the dignity of counts Palatine of the Roman empire. From him too, it obtained the name of Cusareo-Leo/iotdina A'aturx Cu- riosorum Academia. Every member was required to have for the symbol of the academy, a gold ring, on which was an open book, having an eye on the front of it. On the other side was the motto of the academy, Nunc/uam Otiosus. A histoiy of this institution has been written by Buchner, one of its presidents, under the ti- ACADEMY. 71 tie of, Buchncri Hisl see Marcgrave, Hay, Rondc- /fr,anci IViUughbij.

(o) ACCELERANDO, the term for accelerating the lime in the middle of a piece of music, (to) ACCELERATION, in mechanics, is an augmenta- tion of velocity received by a moving body, whether falling freely by its own weight, descending an inclined plane, or oscillating round a fixed centre. The laws of the acceleration of falling bodies were discovered by the celebrated Galileo. See Dynamics, and Mecha- nics, {tu) ACCELERATION of the Moon, or her secular equation, is an increase of velocity in the mean motion of the moon, arising, according to La Place, from a di- minution in the eccentricity of the earth's orbit, produced by the action of the sun. When this eccentricity, there- fore, becomes a minimum, the acceleration will cease, and when the eccentricity increases, the acceleration will be converted into a retardation. Dr Hallcy was the first who detected this diminution in the periodical revolution of the moon, by a comparison of the ancient and modern eclipses. But, as the longi- tudes of the places where these eclipses were observed, were not accurately ascertained, he did not attempt to determine the quantity of acceleration. This, however, was afterwards done by Mr Dunthornc, who found that tlie acceleration amounted to 10" in 100 years. By a comparison of three eclipses, observed near Cairo in 977, 978, 979, by Ibn-Junis, La Lande has found the ac- celeration to be 9". 886 in IDO years. In Mayer's first tables it is 7", and in his last 9". According to La Place, it amounts to 11". 135. See J^hil. Trans. No. 204, 218; and vol. xlvi. p. 162 ; 1749, 1750, 1777.

Qiv) ACCELERATION of the Staus, is die difference between the time in which the sun performs his diurnal revolution, and the time in which the fixed stars seem to perform their diurnal revolution, which makes the stars rise, come to the meridian, and set, 3' 55". 9 sooner every clay. During every 24 hours, the sun moves 59' 8". 5 eastward, (in a direction contrary to that of his diurnal motion,) a space which he describes in his daily revolution in 3' 55".9. If the sun and a fixed star, there- fore leave the same point in the heavens at the same time, the fixed star will return to that point in the space of 23h. 56' 4".l equal to 24h. minus 5' 55".9, while the sun will require 24 hours to arrive at the same point. During the next revolution, the star will gain 3' 55".9, and will reach the point from which it first set out 7' 5 1".8 before the sun.

See Anatomy, (to) ACCENT, in Grammar, a certain mark, or character, placed over a syllable, in order to direct the manage- ment of the voice in pronunciation. The accents which we commonly employ, are the same that were in use among the Greeks and Romans, and are three in num- ber, viz. the acute accent marked (') which denotes the elevation of the voice; the grave accc7it (^), which marks the depression of the voice ; and the circuinjlcj.- acccrit (") or ("), which is composed of the grave and the acute, and indicates that the voice is to be first eleva- ted and then depressed. Different nations vary from each other greatly in the accents which they employ. The Hebrew abounds more in them than any other language, as it is reckoned to employ twenty-five tonic and four euphonic accents ; although authors are not perfectly agreed as to the num- ber of either class. The tonic accents are intended to give the proper tone to syllables, and are divided into grammatical and musical. The euphonic accents are called rhetorical, and are intended to make the pronun- ciation more sweet and agreeable. Of the Hebrew ac- cents, some are placed above and some below the syl- lables ; and they serve not only to regulate the variations of the voice, but also to mark the periods and members of a discourse, like our characters for punctuation. They are classed according to their dignity, or relative importance ; and have obtained the lofty titles of em- perors, kings, dukes, &c. The emperor rules over a whole phrase, and tenninates the sense completely, like our full point ; the king corresponds to our colon, or semicolon ; and the duke to a comma ; but they in- terchange dignities as the phrases are longer or shorter ; and thus the king may become a duke, and the duke a king. The office of these accents is very different in poetry from %\-hat it is in prose. '8 ACCENT. Much controversy has ajisen concerning both the origin and the use of the Hebrew accents. Some main- tain, that they serve to distinguish the sense ; while others allow tliem no other oftice than to regulate the musical cadence, or melody ; alleging, that the Jews sing, rather than read, the scriptures in their synagogues. The learned Hennin afllrnis, that the Hebrew accents are of Arabic invention ; and that they were adopted by the Jewish doctors of the school of Tiberias, called the Masorites, especially by the celebrated Rabbi Ben Ascher. It is not, however, so easy to conceive, that this contrivance could have been of Arabic origin, when the Arabic language has no such thing as accents either in prose or verse. The most prevailing opinion among the learned is, that the invention of the Hebrew accents, as well as the vowel points, is entirely due to the Maso- rites, and took place about the middle of the sixth cen- tury. The accents have been a source of great difficulty in learning the Hebrew language ; and of equal confu- sion and error in its interpretation. Few of them are now of any known use, except that of distinguishing periods ; and biblical interpreters are at great variance concerning their position, necessity, and utility. See Buxtorf's Thesaurus. The Chinese and Siamese are noted for the musical accent with which they speak ; and, in their language, the accents are employed to prevent ambiguity, and to confer a peculiar meaning upon words. They consist of a kind of modulation, or a prolongation, and, at the same time, a variation of the sound of a vowel, by raising or depressing the voice a certain pitch. The accents of the Chinese arc reckoned four or five in number, and the same sound may acquire as many different meanings, according to the accents affixed to it. Thus, the syllable ya, according as it is accented, may signify God, a ivall, excellent, stu/iidily, and a g-oose ; so that if they deviate ever so little from the accent, they say quite a contrary thing to what was intended. The Siamese alphabet begins with six characters, which are all equi- valent to our /t, but are differently accented ; for, in this language, the consonants, as well as the vowels, are diversified by accents. La Loubere, tom. ii. 1.8. With respect to the Greek and Roman accents, there has been no less dispute about their antiquity and their use, than concerning those of the Hebrews. It is the opinion of Vossius, and other learned grammarians, that they are a comparatively modern invention ; and that the most ancient Greek accents were a few musical notes for poetry, invented by Aristophanes the grammarian, about tlie time of Ptolemy Philopater, and which were very different from those afterwards introduced. (Ko.s. de Accent. Grxc.) Montfaucon, while he allows Aris- tophanes to have been the inventor of prosody, and of the marks by which the accents are now distinguished, asserts, that the Greek language was by no means des- titute of accents before his time. {Paleogra/i/i. Grxc. p. 33.) Wetsleen, Gcsner, lord Monboddo, and others, have contended for the high anti([uity of the Greek ac- cents, and endeavoured to point out their specific use. It is not, however, contended, that the ancient Greeks used accents in their common writings, or books, but only in their schools. No Greek inscriptions have either accent, spirit, apostrophus, or iuTo. subscribed, till 170 years after Christ. Michaelis apprehended, that they do not occur in any copies of the New Testament still extant, which are antecedent to the eighth century, and but seldom in those which are more modern ; that thev were not written by the apostles, but were probably first added by Eulhalius in the year 458. His translator, however, Mr Marsh, has discovered botli accents and marks of aspiration, in several more ancient MSS. whicli he mentions ; particularly tlie V^atican, and the Claro- montane. The Alexandrian, Cambridge, and four other MSS. are without accents. Translal. of Michael. In- trod. vol. ii. p. 894. The Greeks called their accents a-fo5-«^(«i, or t»v9<, and the Romans called them accenttis ; terms which seem to show that their effect was musical, or consisted in a variation of the tone of the voice, in respect of acuteness and gravity. This also appears from the three species or varieties of the ancient accents; the acute, whose office, it is said, was to raise the voice to t. greater height in the musical scale; the grave, whose office it was to depress it; and the circumflex, which first carried the voice from grave to acute, and then from acute to grave. The management of these accents was reduced to rule by the ancients, and formed a prin- cipal object of attention with all public speakers. There were academies instituted for the management of the voice, at which those destined for the bar or the stage attended, and received instructions from persons called (poitu.trx.iii, or regulators of the voice. Roscius, the cele- brated actor, had an academy of this kind ; and happened to have a law-suit with one of his pupils, in which Cicero pleaded his cause. Both Cicero and Quinctilian relate the story of Caius Gracchus, when he was declaiming in public, having a musician, or tibicen, stationed behind him, in order to regulate the tones of his voice by a pipe or flute. His employment, says Cicero, was not only to appease the passion of his master, but, upon certain oc- casions, to stir it up : Qui instaret celeriter cum aonum, quo ilium aut rcmiasum excilaret, aut a contentione revo- caret. Many passages might be cited from Cicero, Quincti- lian, Boethius, and Plutarch, in order to prove, that not only musicians and actors, but even orators, had a nota- tion, by which the inflexions of voice peculiar to their several professions of singing, declaiming, and ha- ranguing, in public, were ascertained. This, in the case of haranguing, we may suppose to have been vei-y much of the nature of the ancient accents. M. Duclos {Encyc. art. Declam. des .-Inciens) has denied the possibility of this, on the principle, that the intervals are too minute to be accurately marked or ascertained. The possibility of it, however, has been completely proved by the inge- nious Mr Steele, who was able to imitate, upon a violon- cello, the exact tone of the voice in declamation, as it naturally passes from grave to acute, and from acute to grave ; and to express it in writing'. With a finger on the fourth string of a violoncello, and a corresponding motion of the bow, he imitated the precise tones of speech, by rapidly sliding the finger up and down the string, so as to produce a continued transition of the sound from acute to grave, or tbe contrary. (Prosodia Ratiorialis.) This kind of musical tone is very different from any succession of notes in the diatonic, chromatic, or even enharmonic scales ; for these all consist of inter- vals, or sudden starts from tone to tone. But the music of declamation is a continual and insensible gliding up- wards or downwards, without any sudden transition of tone. It is, however, perfectly suiceptible of notation, and on principles altogether analogous to our common method of writing music, as was shown by Mr Steele, who, to denote this kind of melody, inscribed in the stave ACCENT. 79 (B» five lines, instead of crotchets and quavers, a set of right lines obli<|Ucly ascending or descending Ihrougli a space, corresponding to the musical interval, through which ihe voice naturally glides in speaking. Tliese slidmg notes, or marks of declamation, when taken out of the stave, are tlie exact representatives of the ancient accents; and, if their relative posiLion, as to acuteness and gravity, be retained, tliey may, even in this situation, be sounded truly by the voice with a little practice. Mr Steele Ivad made considerable proficiency himself in analysing and recording the melody ot speech, and could repeat a sentence, which he had committed to paper with the accented tones, nearly as correctly as if it had been set to music. His success, in this way, made him so sanguine, as to cherish the expectation of " transmitting to posterity the types of modern elocution, as accurately as we have received the musical compo- sitions of Corelli." The investigations of this ingenious author have, we think, clearly established, that there is a musical accen- tuation in all pleasing declamation ; and that this accen- tuation may be very accurately expressed by notes or characters ; yet, after all, we cannot help thinking, that the ofRce of the Greek accents, which have descended to us, was considerably different from this. The accents of declamation must vary considerably on the difi'erent words and syllables, according to the nature of the sub- ject, otherwise the expression cannot be just or pleasing. It is pretty clearly shown by Mr Steele, that, when we utter the interjection oh.' under the strong impression of wonder or surprise, we use a circumflex musical slide, first ascending, and then descending, through no less an interval tlian a whole octave, thus, oh .' But the same in- terjection is employed as indicative of many other feel- ings of the mind, such as affection, sorrow, compassion, &c. ; and on each occasion the musical accent will be different, or the expression cannot be just. When it denotes sorrow, the tone of the voice continues all the while nearly at the same pitch ; for it is the natural cha- racter of grief to be monotonous. Unquestionably, the declamation of the Greeks had analogous properties, or it must have had a defect unknown to any living lan- guage ; it must have been completely destitute of senti- mental expression, as inanimate as writing, and as mo- notonous as the cant of a parish clerk. Yet tlic Greek accentual marks are invariably attached to particular syllables, whether the subject be serious or gay, rheto- rical or didactic ; and whether the sentence be in the form of a simple proposition, a command, an insinua- tion, or an interrogation. The inference appears to us unavoidable, that the Greek accents are not rhetorical marks, expressive of sentiment ; but grammatical signs, indicative of emphasis, quantity, or signification ; and this conclusion is greatly strengthened by the compara- tively modern date which is, with probability, assigned to these characters. The rules which grammarians have given, respecting the Greek accents, are very perplexed, and liable to many exceptions. The whole difficulty of the matter, say Messrs de Port Royal, consists in two points ; first, in knowing the quantity of the ultimate and penultimate ; and, secondly, in knowing on what syllable the words should have their elevation by nature ; because, even supposing the same quantity, the elevation may not be the same. Thus, in avS^ws-o;, the antepenultimate is acute ; but in avS^a^ris, the penultimate. The utmost lUtitude of the acvite accent, among the Greeks, was, that it might occupy some one of three syllables, the ultimate, pcnultiniate, or antepenultimate. Among the Romans, the kititude was not so great; for it necessa- rily occupied either tlie penultimate or antepenultimate. Among them, too, the rules for placing it were very precise; viz. that, in dissyllables, it always occupied the penult, or first syllable ; in polysyllables it occupied the penult, if it were long, and, if it were short, the ante- penult. (See Diomedes de Accent, lib. ii. antl Quinct. Innt. lib. i. c. 5.) In Latin words, it is well known, that the accentual marks served to distinguish the meaning conveyed; and, though disused in the English, they have been retained in the French for a similar purpose, or for marking the promniciation. In some Greek words, they undoubtedly have alike effect; thus, .^e«« denotes a goddess, and Sr'ia a show, with no other difference than that between the acute and the grave accent. Thus, also, n>f]^iic]ovoi, accented on the second syllable, deno- ted, slain by a mother; but /j-ifl^oxjivoi, accented on the third, meant a matricide. In most cases, however, the effect of the Greek accents must have been very differ- ent from this. Various arguments have been adduced to prove, that the purpose of the Greek accents was to indicate the stress, or emfihusis of the voice, which is tlic effect that we now denote by the term accent; since, by an accent- ed syllable, we mean, in fact, nothing more than an em- phatic syllable. All polysyllables, it has been observed, required one acute or circumflex Greek accent ; ours require one emphasis. The accent was never removed farther back, by the ancient Greeks, than the antepenult syllable ; neither is our emphasis, except in a few cases, where it resembles the practice of the modern Greeks. The ancient accent was invariably fixed upon a particu- lar syllable of a word ; so is our emphasis. It was changed, however, to another syllable, in derivative words, differing in length ; or in similar words, differing in sense ; so is our emphasis precisely. The Greek circumflex was never placed On any short syllable, nor farther back than the penult; oxir long syllables, i. e. our long vowels and diphthongs, are generally emphatic, and are pronounced with a circumflex, or rising and falling inflexion of the voice. But, says Mr Sheridan, our accent, or emphatic pro- nunciation of syllables, has the effect of lengthening the vowel, or syllable, which is accented, while the Greek accent often falls upon a short vowel ; and therefore, upon this supposition, would be destructive of the rythm, or proportional length of the syllables of words. It is, indeed, true, that the laying the stress of the voice upon the voiuel of a syllable, renders that syllable long, as in glffnj, father, ho'ly. Sec. ; but it is equally true, as is ad- mitted by the same author, that, if the stress be laid, not upon the vowel, but upon the consonant which fol- lows it, the syllable may continue short, as in habit, bat'- tle, bor'row, &.C. It may, indeed, be supposed, that, in such cases, the accented syllable is lengthened by the virtual repetition of the accented consonant, b, t, or r ; but, in fact, we seldom redouble a letter in pronuncia- tion, even when it is written double. It is only in such compounds as oi'er-run, or where a mute e intervenes, as in supine7iess, that this takes place. Thus, an ac- cented syllable may be long or short, according as the vowel, or the consonant which follows it, is rendered emphatic ; and we may observe by the waj^, that it is the genius of the Scotch pronunciation to dwell upon the vowels, and of the English to accent the consonants. 80 ACCENT. Thus, instead of ihe English hii'bit, and bat' tie, a Scotch- man naturally says ho/bit, and balftle. The English, therefore, abounds in the acute accent, the Scotch in the grave, and, it may be added, the Irish in the cir- cumflex. From these observations, we think it clearly follows, that a syllable may be rendered emphatic, and yet con- tinue short ; and, on this account, the metrical propor- tion of syllables may be retained, although the accent (supposing it the same with emphasis,) be placed on those which are short, and not on those which are long. Thus, the proportional length of all the syllables in ft))7j«K7oKi« may continue the same, whether wc place the emphasis, or accent, on its second or its third syllable, if, in this last case, wc lay the stress on the », and not on the 0.* By this variation of the accent, we are able to mark the change of meaning of the word ; and thus we discern one use of the accents, corresponding to the purpose for which they were said to have been invented by Aristophanes of Byzantium; namely, to facilitate the progress of foreigners hi the proper pronunciation of Greek words. It must be acknowledged, however, that there is a passage in the treatise of Dionysius of Halicarnassus concerning com/ionition, which is rather inconsistent with this doctrine concerning the use of the Greek ac- cents, and is more favourable to the system of Mr Steele. " The melody of common speech," says this critic, " is measured nearly by one interval, that, namely, which is commonly called the dkijienta. It docs not rise more • This appears to be an unnecessary distinction; and indeed, it may be demonstrated not to be founded in fact, which may easily be done by comparing the pro- nvmciation of the long accented Italian syllables with that of the short ones of the English language that are likewise accented. Take, for instance, the Italian word bello, in which the e is pronoimced very long and strong- ly accented, while at the same time the two Us are suc- cessively articulated in the clearest and most distinct manner. Take, on the other side, the English word folly., in which the o, though accented, is pronounced extreme- ly short. If the accent were really on the / that follows it, that consonant would, as in the Italian language, be arti- culated distinctly and separately from the other I; instead of which the two Us are blended and articulated toge- ther as if there were only one, and produce but a weak liquid sound ; which is pronounced by an English organ with not half the strength that is given by an Italian speaker to one of the two Us that are contained in tlie word which we have adduced by way of example. We must acknowledge with great diffidence, that we do not perceive any necessity for the distinction which is at- tempted to be here established ; nor can we see any rea- son why a short vowel may not as well be accented, or in other words, strongly and emphatically uttered as a long one. We therefore venture to think that in short syllables, as well as in those that arc long, the emphatic accent is really placed on the vowel itself, and not on the consonant by which it is followed. Grammarians have too long blended together the ideas of accent and quantity, and seem to be now seeking pretexts or apolo- gies for keeping them separate. To us it appears that no two things can be more distinct, and that there is no need of calling in the aid of the consonant to prove the accentuation of a short syllable. Duponceau. than three toiics and a half towards the acute, nor does it descend farther towards the grave. But every word has not the same tone ; for some are sounded with an acute tone, some with a grave, and some with both. Of these last, some have the acute and grave blended toge- ther in the same syllable, which is then called circum- Jlectcd; others have them on different syllables, each of which preserves its own proper accent, whether grave or acute, distinct and separate from that of any other. In dissyllables of this kind, the one is grave and the other acute ; and betwixt these there can be no medium ; but in words of many syllables, of whatever kind, there is but one which is accented acute, while all the rest are grave. Such is the melody of speech." Sect. 11//;. To obviate this difficulty, however, it may be reasonably supposed, that the observations of Dionysius apply to the accents of oratory or declamation, which were re- dTiced to rule by the ancients, and even represented by written characters; but that they have no reference to the grammatical accents which we at present possess. Considerable light has been thrown upon this contro- verted question, by an examination of the pronunciation of the modern Greeks, who may retain many particulars of the manner of speaking of their classical ancestors. Even here, however, the testimony of authors is contra- dictory, and respectable authorities may be produced on both sides of the controversy. Mr Marsh, the learned translator of Michaelis, informs us, that Eugenius, a Greek priest, and archbishop of Cherson, in reading Greek, distinctly marked, by his pronunciation, both ac- cent and quantity ; lengthening the sound, without raising the tone of his voice, when he pronounced a long sylla- ble, which had not an acute accent, and raising the tone of his voice without lengthening the sound, when he pro- nounced a short syllable which had an acute accent ; in the same manner as in music, the acutest note in a bar may frequently be the shortest. A very different account of the practice of the modem Greeks is given by Mr Browne, {Irish Trans, vol. 7.) who had an opportunity of conversing with the crew of a Greek ship from Patrass, a to^vn situated near the an- cient Corinth, which had been driven, by stress of wea- ther, into the port of Dingle in Ireland, and continued there for a considerable time. " Of the two first persons whom I met," says Mr Browne, "one, tlie steward of the ship, an inhabitant of the island of Cephalonia, had a school education : he read Euripides, and translated some easier passages without much difficulty. The companion, however, of the steward, could speak only modern Greek, in which I could discover, that he was giving a description of the distress of the ship ; and, though not able to understand the context, I could plainly distmguish many words, such as J'fuJf a, |vAoy ; and, among the rest, the sound of Ai^^Sve^ pronounced short. This awoke my curiosity, which was still more heightened when I observed that he said AiB-qa-rov long, with the same attention to the alteration of the accent with the variety of the case, which a boy would be taught to pay at a school in England. Watching, therefore, more closely, and asking the other to read some Greek, I found that they both unifoi-mly pronounced, according to accent, without any attention to long or short syllables where accent came in the way ; and, on their departure, one of them having bade me good day, by saying KaXr.fci^cc, to which I answered, KaXyi^Ji^x, he, with strong marks of reprobation, set me right, and repeated K«A);fcFf«; and, with like censure, did the captain, upon ACC ACC 81 another occasion, observe, upon my saying SacrSlea, in- stead of Socrates." Mr Bro\vne proceeds to inform us, that the most in- telligent of these Greeks repeatedly assured him, that Greek verse, as well as prose, was read by accent, and not by quantity ; and exemplified it by reading in that manner several lines of Homer, with whose name they seemed perfectly well acquainted. When, however, a syllable with the acute accent followed one with the cir- cumflex, as in the case of KXSSi, it was shortened, on ac- count of the great length of the preceding syllable. " I must here add," saysMr Browne, " that these mencon- firnned an observation, which I have heard made, that we are much mistaken in our idea of the supposed lofty sound of 9ro>iw^Ao/s-/3o(o .9-«A«ff-vUl appear, even if we retire into a dark room ; but this is physically impossible. From the duration of the impressions of light upon the retina, the square may, in this case, appear of its natural colour, and actually does so; but the presence of light is absolutely neces- sary to the generation of accidental colours. In order to show, that the same colour results from the combination of accidental colours, as from the com- bination of real ones, professor Scherff'er placed two small squares, in contact with each other, upon a black ground, the square on the left being yellow, and that on the right red. He then fixed his eye for a few seconds on the centre of the yellow square, and, without moving his head, he fixed it for the same time on the centre of the red square ; his eye was then returned to the yellow square, and the operation of viewing each stjuare alter- nately was repeated three or four times. When this pait of tiie experiment was completed, he turned his eye to a white wall, on which there appeared three squares, in contact with each other. The square on the left was viulct, the middle square was a mixture of green and dlue, and the colour of the right hand square was a vivid green. When the eye is fixed on the yellow square, the image of it falls upon the centre of the retina, and pro- duces an accidental colour of indigo-violet ; but when the eye is transferred to the red square, its image falls likewise upon the centre of the retina, and produces an accidental colour of bluish-green ; consequently the mixture of these accidental colours produces green and blue, wliich is therefore the accidental colour that ap- pears in the middle square. But while the eye was fixed on the yellow square, the image of the red square fell upon one side of the centre of the retina, and pro- duced the accidental colour of green, which appeared in tlie right hand square ; and, while the eye was fixed on the red square, the image of the yellow square fell upon the other side of the centre of the retina, and produced the accidental colour of indigo-violet, which appeared in the left hand square. This, we presume, is the true explanation of the phenomena, and may be applied to the following experunents of Scherffer. Number and order of the Accidental Colours. Blue Yellow Red Deep Blue Violet with much Red Reddish Orange Green Dark brown Reddish Deep pur- Deep Green and pie blue blue Pale yel- Greenish Deep Green and low blue green blue Pale Red Pale Yellow Red Green Green The preceding experiments, which were intended merely to prove the mixture of accidental colours, might have been conducted with much more simplicity. If, for example, in the case of the yellow and red squares, the one were always concealed when the eye was exa- mining the other, then, if the eye, after an alternate exa- mination of each square, were transferred to a white ground instead of three squares, it would perceive only one, which will be found to be a combination of the two accidental colours, like the middle square in Scherffer's experiment. The eficctof the experiment will be still more beautiful when one of the squares is larger than the other. If we make the red square largest, and exa- mine the two squares as before, we shall have, by turning the eye to a white surface, the appearance of one square enclosed in another: the interior square will be green and blue, or the mixture of the accidental colours of the red and yellow squares, while the exterior square is the accidental colour of tlie red square. If the yellow square is the largest, the interior square will be the same as be- fore, but the exterior one will be the accidental colour of yellow. In the course of his experiments, BufTon remarked, that the figure and colour of a red square underwent several curious transformations, by looking at it steadily for a very long time. These phenomena, however, were observed after his eye had been reduced by fatigue to an extreme degree of debility ; and, therefore, it would be absurd to attempt an explanation of appearances, which probably arose from the diseased state of the organ. The subject of accidental colours has been investigat- ed by M. iEpinus ; but he has attended only to tljose ACCIDENTAL COLOURS. 85 phenomena which were produced by the impression of some illusion attending; it, I sliall insert the account the solar image upon the retina.

Dr Darwin vciy properly infers, from the theory of accidental colours, that in the dial-plate of a clock or watch, or in a book printed with small types, the letters or figures should be of such a colour, that their spectra or accidental colours may be of the same hue as the ground on which they are placed. When this is done, the letters will appear most distinct, because the spectra arising from the unsteadiness of the eye cannot become visible. We conceive, however, that the theory is capa- ble of a much more extensive application, and that, at some future time, which is not far distant, a knowledge of accidental colours will be deemed absolutely necessa- ry to the manufacturer in the fabrication of coloured stuffs. It will be unifomily found, that, in every combi- nation of colours, those are the most pleasing to the eye, in which the prominent colour is placed upon a ground similar to its accidental colour : the general efi'ect will not be injured by the appearance of partial or complete spectra, and the organ of sight will not be distracted by floating images alternately soliciting his attention, and escaping from his view. Whenever theory seems to come in contact with practice, the connexion should be diligently traced tlirough all its consequences ; for it is frequently thus that philosophy becomes the handmaid of the arts. Before concluding this article, we shall present the reader with a new theory of accidental colours, proposed by the celebrated La Place, and published in the 2d edition of Haiiy's Tniiie dt Pliysi(jue. La Place sup- poses, " that there exists in the eye a certain disposi- tion, in virtue of which, the red rays comprised in the whiteness of the ground are at the moment when they arrive at that organ, in a manner attracted by those which form the predominant red colour of the circle ; so that the two impressions become blended into one, and the green colour finds itself at liberty to act as though it existed alone. According to this method of conceiving things, the sensation of the red decomposes that of the whiteness, and while the homogeneous actions combine together, the action of the heterogeneous rays which are disengaged from the combination produces its effect separately." This hypothesis, unauthorized by experi- ment, is intitled to our regard solely from the imrivalled genius of its illustrious author. In a subsequent article, in which we propose to give a new theory of acciden- tal colours, founded on a number of experiments, we shall be able to give a direct refutation of La Place's theory. The writer of this article is engaged in a set of ex- periments connected with accidental colours, by which he expects to reduce the various colours in nature to a fixed nomenclature, — to ascertain the elements of which they are composed, and the proportion in which these elements are combined ; and to determine the duration of the impression of light upon the retina, when ■ proceeding from bodies of various colours, and under different degrees of illumination. The results of these experiments may probably be comnmnicated in some subsequent article. Those who wish to study the sub- ject of accidental colours, are referred to the works already quoted, and to Jiirin's Essatj on Distinct and In- distinct Vision, at the end of f>?)iith's 0/itics.

Plutarch informs us, that her name was used by mothers to terrify their children. See Plutarch, de Utoic. Ne/tugnant. p. 1040, and Calius Rhodiginus, lib. vi. cap. 15. and lib. xvi. cap. 2.

He was highly esteemed, and publicly patronized by Decimus Brutus, consul in 615, whose victories he had celebrated in several poems, and who, in return, caused some oi his verses to be inscri- bed on the temples and monuments that were erected in honour of his military triumphs. {Cic. de Archia Poeta, c. xi. Valer. Max. lib. viii. 14.) The subjects of his tragedies were taken principally from the Grecian his- tory ; and fragments of no fewer than fifiy of them, among which are two intitled Medea, are still extant, but in such a mutilated state, that it is impossible to form any correct opinion of his merits as a dramatic author. He composed, however, at least one tragedy en- tirely Roman, called Brutus, which related to the ex- pulsion of the Tarquins ; and he is supposed, not without some probability to have also written comedies. Be- sides his dramatic writings, he was the author of Annals, in verse, which are mentioned by Macrobius, Priscian, Festus, and Nonnius IVIarcellus ; and, according to the testimony of Aulus Gellius, of a treatise in prose, called Didascalida, relating to poets and poetry. He was held in such high estimation by the public, that a comedian was punished for only mentioning his name on the stage. His style has been censured for its harshness, but this Quinctilian ascribes more to the age in which he lived, than to his negligence ; and, when speaking of him and his contemporary Pacuvius, passes a high encomium on their tragic works, as excelling in dignity of sentiment, force of language, and majesty of character. The opinion of some, that his talents, as a historian, are de- rided by Cicero, {De Clar. Orat. and De Legibus,) is fully refuted, not only by the frequent honourable men- tion that is,made of him in the writings of that orator, but by the fact, that the Accius, of whom Cicero speaks contemptuously, wrote in prose, whereas the Annah of Lucius Accius were in verse.

In a more restricted sense, it denotes a certain formula of words, uttered with extraordinary ve- ACCLAMATION. 87 hemencc, and in a peculiar chanting tone, frequent in the ancient assemblies. Acclamations were generally accompanied with ap- plauses ; liom which, however, they ought to be distin- guished, applause being given by the liands, and bestowed only on persons that were present; acclama- tion, by the voice, and on those also who were absent. Acclamation was sometimes given, by women, hut ap- plause seems to have been confined to men. Acclama- tions are of diftcrent kinds ; 7xujitial^ ncholastic, theatrical, jiiilitarij, senatorial, and ecclesiastical. The formulae, or expressions used in acclamation, were of various kinds, corresponding to the occasion on which they were employed, though as will be im- mediately noticed, the same forms were frequently used, even when the subjects to which they related were dis- similar. Indeed, being merely general expressions of joy and respect, or of reproach and contumely, it is naturally to be expected, that they will resemble one another. Acclamations were an essential part of the nuptial ceremony, both among the Greeks and the Romans. Thus epithalamian songs, both on the evening of the marriage and the morning after, may be regarded in this light ; for in these the praises of the bridegroom and bride were celebrated, and fervent wishes for their happiness expressed. The Roman formula was, in general, Feliciter, or lo Hymen. These were the Ixta o;H/«n, mentioned by Seneca, {In Octav. iv. 1. 704.) with v/hich the citizens hailed the nuptials of Nero and Pop- paea. The scholastic acclamations are those which were bestowed on authors, who recited their works, either in the public assemblies, or the more private academies ; and their admirers were careful that they should be con- ferred in the most solemn and respectful manner. In- vitations were sent, and presents sometimes given, to procure them ; nor was it uncommon for men of fortune to keep able applauders in their service, and lend them to their friends. These acclamations were frequently accompanied with music ; and the formulae were varied according to the character of the author, and the nature of his compositions. One of the most usual forms was c-ntpa, or, perhaps crofoii, luisihj, repeated three limes ; {Martial, i. 4, Sec.) and sometimes i7r£^(pvSi;, i. e. supra quain did fiossit. The same author (ii. 27. S.) compre- hends several other customary forms in this verse : "Effecte, ^i-uviter, cito, nequiter, Euge, Beate." The acclamations of the theatre, simple and artless during the first ages of the Roman commonwealth, were gradually changed, from confused and tumultuous shouts, into a sort of regular concerts. In this form they ex- isted during the reign of Augustus, but were still more highly improved by Nero, who himself played on the stage, and gave the signal to the band of acclaimers, which on one occasion consisted of five thousand sol- diers, called ^i/^2/sra/s, who immediately began to chant his praise, and the spectators were obliged to repeat them. The responses were conducted by a music master, called M< rocliorus, or Pausarius. At the public festivals and games, as well as in the theatres, accla- mations were given not only to the emperors, their children, favourites, and the magistrates who presided, but to others of distinguished literary or civil merit, to the actors, and to those who carried off the prizes. The most common foniiulae were Jnno» fclices, Longiorem. vitam, feliciter. Those with which the victories of the Athletae were honoured, were loud and extravagant, ac- companied with violent gestures, expressing sometimes compassion and joy, sometimes horror and disgust. Military acclamations were employed Ijy the Romans at the election of their commanders, when the soldiers exclaimed, Dii te sencnt im/ierator ; and when about to engage the enemy, they cried out Victoria. {Cj:sar,dc Bell. Gall. v. 36.) The Greeks also began their battles with a general shout, called a,Xct,>.a,yfA.ii(i, from the soldiers repeating the word «AaA, and, according to Suidas, some- times tXiXiv. This custom indeed was general among all ancient nations, and still exists in many parts of the world. When a war was finished, or the enemy com- pletely routed, the victorious army expressed their joy, by pronouncing aloud the name of their commander; and after their return, their acclamations were increased, and re-echoed by the citizens, whilst they marched in procession to deposit the spoils in the capital. The city resounded with the cry of Salve imjierator, Vestra salus, ^J'ostra salus, or lo triiunjihe. So Horace, in ad- dressing Anton. lulus, says : " Tuque dum procedis, lo tiiumphe, Non semel dicemus, lo triuniphe, Civitas omnis." — Od. 11. lib. iv. 49. The acclamations in the senate, though more so- lemn, were evidently borrowed from the theatres, being made, not at the pleasure of any individual, but, as in the choruses, by the direction of a person appointed for the purpose. They do not seem to have been intro- duced till about the time of Trajan ; and were so much abused, and so inconsistent w ith the dignity of the court, that Claudian procured their abolition. But flattery be- ing always pleasing to tyrants, the custom was soon re- sumed ; the emperors receiving not only at their first election, but whenever they entered the senate, that in- cense of adulation which is offered to the rank, oftener than to the merit, of princes. The same may be said respecting the acclamations of the populace, which were as liberally conferred on the stupid Vitellius, and the sanguhiary Nero, as on Trajan, who so trulv deserved the title of Ojitimus. When the emperors gave largesses of money or pi-ovisions to the people, the form of accla- mation commonly was, " De nostris annis tibi Jupiter augeat annos." (Tertull. Apol. c. 35.) The Greek emperors were afterwards greeted with acclamations, taken from those of the Romans, the peo- ple chanting out, UaXXx i]yi, " Many years." Nay, Plu- tarch mentions an acclamation so loud, on the occasion of Flaminius restoring liberty to Greece, that the birds fell from the sky at the shout. The Turks still observe a similar ceremony at the sight of their emperors and grand viziers ; and the custom of saluting kings, con- querors, and distinguished persons, with some forms of acclamation, is very general and prevalent. At first confined to amusements and political subjects, acclamations were at length practised in ecclesiastical assemblies. Sermons were applauded with the hands and feet, the people most extravagantly and absurdly interrupting the preacher, by calling out, " Orthodox 1 Third Apostle !" Sec. whilst they shook their loose gai'- ments, and waved their handkerchiefs, in token of their approbation. This practice was condemned by Chrysos- tom, yet tolerated by Augustine ; but good sense, and religious decorum, at last succeeded in banishing it from as ACC ACC the solemn services of Christian worship.

(rf) , ACCOLADE, or Accolee, from ad and collum, the name of a ceremony employed in the conferring of knighthood. It conbisted, according to some antiqua- rians, in an embrace, or kiss, with which the king ho- noured the new knight as a mark of esteem. Gregory de Tours informs us, that the kings of France formerly kissed the knights on the left cheek, when they conferred the gilt shoulder-belt. It is the opinion of other anti- quarians, that the ceremony in question was perfomied by givmg a blow on the chine of the neck. According to John of Salisbury, the accolee, or blow, was used among the ancient Normans ; and William the Conqueror conferred the order of knighthood upon his son by a similar process. The blow was originally given by the naked fist, according to Lambertus Ardensis, but was af- terwards changed into a stroke with the flat of the sword upon the knight's shoulder. Fauchet endeavours to re- concile these two opinions, by supposing the kiss to be in- tended as a stroke upon the cheek, (w) ACCOLTI, Bernardo, surnamed L'U»ico, or the A'o7i-such, from the wonderful strength of his under- standing, and the variety of sciences with which he was acquainted. His talents as a poet gained him a seat among the academicians of the court of Urbino ; and so high v/as he in the esteem of Leo X. that this generous patron of literature created him prince of the state of Nepi, in 1520. The generosity of Leo was immediately rewarded by a poem, still in MS. inlitled, " The Libera- lity of Pope Leo X." The reputation of Accolti was so great, that when he was to recite publicly at Rome, all the shops were shut, the people flocked to hear him, princes and prelates honoured him with their presence, and every ceremony was observed which could give pomp and solemnity to the scene. The talents of Ac- colti, however, seem to have had more splendour than solidity, and he appears to have excelled more as an im- provisatore, than as a poet, (o) ACCOMMODATION, the application of one thing by analogy to another, in consequence of a resemblance, either real or supposed, between them. To know a thing by accommodation, is to know it by the idea of a similar thing referred to it. In theology, the term accommodation is applied to what may be called the indirect fulfilment of prophecy ; as when passages, that originally related to one event, are quoted as if they referred to another, in which some resemblance may be traced. The method of explaining scripture on this principle of accommodation, serves, it has been said, as a key for solving some of the greatest difficulties relating to the prophecies. It has been justly called a convenient principle ; for, if it were once gen- erally adopted, we should get rid of the strongest proofs of the truth of Christianity, w'hich prophecy has hither- to been supposed to furnish. It is not affirmed, that this is either the wish or the design of some of the au- thors who have adopted and defended the pi-inciple of accommodation ; but scarcely any of them, with the ex- ception perhaps of one or two German divines, have pleaded for its unlimited application to the Old Tes- tament predictions. It is vain to press even Michaelit into the service, as has been lately attempted ; for both he, and his no less acute and learned commentator Marsh, expressly avow, not merely their doubt of the propriety of universally extending this principle, but their conviction of the danger with which it would be attended, and of the inconclusive reasonuigs which its pati-ons have brought forward in its dctcnce. (Vid. Marsh's Michaelis, vol. i. p 200 — 214. and Notes, p. 470 — 479.) The ibllowing view of the subject is taken chiefly from their statements. This mode of interpreting the prophecies was early introduced among theologians, probably by Origen, who employs it under the name oiOiMsofnu,, (which the Latin fathers afterwards called dinjienauito,) in replying to th« objections of Celsus; and whose allegorical disposition did such injury to the cause of truth. Tlicy ex- pressly affirmed, that the apostles accommodated their quotations from the Old Testament to the prejudices of the Jews, without any regard to their original import ; an opinion the most unwarrantable and dangerous ; for that those who were commissioned to publish the re- velations of God to mankuid, should have recourse to such an unjustifiable anifice, is contrary to all the no- tions wliich sound reason, the ultimate judge of tlic truth of revelation, leads us to form respecting the di- vine character and conduct. Dr Eckermann extends the doctrine of accommodation to every quotation in the New Testament without exception ; proceeding on the hypotliesis, that the Old Testament contains no pro- phecy which literally and immediately relates to the person of Jesus Christ. Dr Owen, on the contraiy, in his "Modes ot Quotation," § 5. entirely rejects the prin- ciple of accommodation ; to whose opinion Michaelis is, in most cases, inclined to accede, though with this es- sential difference, that he admits only a grammatical and literal, whilst Dr Owen contends for a typical, mean- ing of particular passages. With respect to the quotations from the Jewish scrip- tures, contained in the New Testament, it seems neces- sary to make an accurate distinction between those which, being merely borrowed, are used as the words of the person who quotes them, and those which are pro- duced as proofs of a doctrine, or the completion of a prophecy. In the one case, accommodation may be allowed ; for it is n'atural to suppose, that the writers of the New Testament, from their intimate acquaintance with the Septuagint, might often allude to passages, and quote them from memory, as an illustration of what they were stating, without directly intending to bring them forward as irresistible arguments. But, in the other case, there is no little difficulty, and even hazard, in having recourse to this principle ; for if it once be ad- mitted, that the evangelists and apostles, and even our Lord himself, employed arguments which, on this sup- position, are evidently no arguments at all, the mspira- tion of the one, and the divine mission of the other, must be extremely equivocal. If it were true, that the Old Testament was falsely quoted in the New, when either doctrines or prophecies are the subjects of discussion, it would be necessary to make the following distinctions. (1.) If such quotations were discovered in a book, whose canonical authority is doubted, they must be regarded as human errors, and the inspiration of the book itself be abandoned. (2.) If they could be found in those books which belong to the ojnoAoySiM-eva, the inspiration of these books also must be given up, though no inference could be drawn that the apostles were not preachers of a divine religion. But (3.) were it possible to show, that the very author of our religion had made a wrong application of any text ACC ACC Hi of the Old Testament, it would follow, that he was not infallible ;iuid lliut Christianity itself wus false. It seems panieulai'ly obvious, tliat the prineiple of ac- coinmodauon should not be hastily adopted wliere the strong expressions are used, " This was done that it might be fullilled which was spoken by the prophet ;" or, "Then was fulfilled that which was spoken," &c. A formula of this kind is never used in quoting from a classic author; it is, therefore, no arguiueiit hi favour of accommodation, in these cases, to say, with Nicholls, f Conference ivith a T/idst, P. HI. p. 11.) that no one would object to a writer who should address the apos- tles, in the words of Virgil's invocation of the Sun and Moon, Vos o clarissima mundi Lumina. Every one must perceive that these cases are quite dis- similar, and that when the sacred writers used the above expressions, they were persuaded, that the passages which they introduced did directly refer to the events to which they applied them. Wetstein fJVote on Mat. i. 22.) alleges an example of similar latitude of expres- sion from Ephrem Syrus ; and Dr Sykcs {Introduction to t/if Hebrews, § 3.) appeals to other writers also. The authority of Jerom, however, whom he quotes among the rest, is of little weight, as that learned father was an avowed allegorist. The examples of Wetstein, and those which Dr Sykes has <|U0tcd from Epiphanius and Olympiodorus, are not much more conclusive, being only similar to the language which we would use in cautioning any one, "Let not that be fulfilled in thee ;" where the caution itself implies, that the words to which wc allude are no prophecy. Dr Sykes, indeed, affirms, that if we were better ac- quainted with the Jewish phraseology, we should less hesitate in admitting the principle of accommodation. As to the particular term " fulfilled," he says, the Jew- ish writers *ery often meant no more by it, than the Jiappening of a similar event, or an exact agreement in particular circumstances of latter things with former : and that the masters of the synagogue, applied pas- sages of the Old Testament, in senses very remote from that of the original author. But, not to insist on the impropriety of putting the inspired writers of the New Testament on a level with the Jewish Rabbis, it must not be concealed, that this learned author has pro- duced no examples from the Talmud, or from any Jew- ish commentator, where similar expressions are used incases of mere accommodation ; and no assertion can be admitted without authority. This omission is the more inexcusable, that the very principle which he de- fends, rests almost entirely on the decision of the ques- tion. Did the Rabbis, in quoting passages from the Old Testament, with a formula of this kind, " In this the scripture was fulfilled," consider these passages as di- rectly referring to the events to which they applied them ? or did they ground the quotation on a mere parity of cir- cumstances ? It is no small presumption against his as- sertions, that Surenhusius, who has accurately examined this question in his B(/3Ao? y.«T«AA£tyi!? (Amstcrd. 1713,) decides against them. In his third thesis, " Dejbnnii/is allegandi" he compares the expression, etAdj si.^ji ti y^aipii, with the rabbinical formulae ; and, referring to the Tan- chuma, fol. 39. col. 3. where Deut. xvii. 7. is quoted with the formula, " ad conjirmandum id ijuod scri/itum rst-,'' observes, " fjc cujus loci a/iplicatione /infet itlain \'oL.

((/) ACCOMPANIMENT, in Music, a vocal or instru mental accessory, which may consist of an unlimited number of parts, to supply the ncccKsaiy chasms, and to heighten the general eH'cct. Accompaniments must be executed with much skill and delicacy, and in such a manner as to fulfil not only the objei t of the composer, but to admit of the leader givhig the full efl'cct' to the composition; which will otherwise make hut a feeble impression, though in the most skilful hands. Accom- paniments are in no degree susceptiljle of embellish- ment ; a circumstance which is too often overlooked. It is extremely difficult, without a previous knowledge of the composition, in the person accompanying, to treat an accompaniment in a way which is at once judicious and pleasing. It is generally believed, that the accom- paniments of the ancients consisted in nothing more than playing in octave, or hi antiphony, to the voice ; though the Abbe Fraguler has endeavoured to prove, from a passage in Plato, that they had actual symphony, or music in parts, (c) ACCOMPLICE, one who is associated with another in the commission of any crime. By a general rule of the Scottish law, the evidence of an accomplice against a criminal is not received, unless in cases of treason, secret crimes, and those particular cases which are ex- cepted by statute. That tlje accomplice may have no motive to give false evidence, he always receives par- don before his evidence is taken.

He employed himself in the ineritorious office of rescuing the works of older au- thors from oblivion ; a species of labour which is fre- quently more useful than the composition of new ones. He published a learned work, entitled, " JJiairibx, in Jusonium," Sec. in 1524, which is much esteemed as a specimen of critical skill. The authors whose works he corrected are Ausonius, Ovid, Claudian, and Solinus. In 1 535, he published an edition of Ammiaiuis Marcel- linus, containing five books more than any other edition ; though the first thirteen are still wanting. He was also the original editor of the " Epistles of Cassiodorus," and his "Treatise on the Soul." In 1531, he published a facetious dialogue, in which he ridiculed tlie affected use of antiquated phrases, with which his contempo- raries corrjipted the Latin language. Accorso was ac- cused of having, in his notes upon Ausonius, appro- priated to himself the labours of Fabricius Varano ; but the solemn and determined oath with which he repelled this charge of plagiarism, is a strong proof of his inno- cence, and of the anxious solicitude which he felt about his literary reputation. Accorso was likewise the aii- M sclves at supper in the following manner : In the csenaculum, or dining-room, three couches were placed around the table ; three per- sons reclining on each couch. They reclined on the left arm, with the head a little raised, and the back sup- ported by cushions. The feel of the first were stretch- ed behind the back of the second, and the feet of the se- cond behind the back of the third. Thus the head of the second was opposite to the breast ef the first, sepa- rated only by a pillow ; and when any of them wished to converse with another, placed higher on the same couch, he was obliged to lean upon his bosom. The middle place was reckoned the most honourable ; but ^vhen a consul happened to be present at an entertain- ment, he occupied the lowest place on the middle couch ; because there he could most conveniently receive and answer messages. Before coming to table, the guests put on the cisnatoria veslis, or dining garment ; and pulled off their slippers, that they might not injure the couches. (/■) ACCUSATION, (compounded of ad, to ; and causari, to plead ;) an assertion, imputing to some person a crime, or a fault : in law, a formal declaration, charging §ome person with an act punishable by a judicial sen- tence. "In Rome, where there was no calumniator fiub- licus, no attorney-general, every one was permitted to prosecute crimes that had a public bad tendency ; and, for that reason, are termed public crimes. This was a faulty institution ; because such a privilege given to in- dividuals could not fail to be frequently made the in- strument of venting private ill-will and revenge." Kames's Law Tracts. It is a general rule of British jurisprudence, that accusation Is competent only at the suit of tiie Crown, in behalf of the public, or of the pri- vate parlies themselves, wliomay happen to be aggriev- ed. In Scotland, the power of accusation in behalf of the public is committed to the King's Advocate, and to the procurators Ji.icul of such of the inferior courts as possess criminal jurisdiction. Penal actions at the suit of private parties require the concurrence of the publio prosecutor ; but that concurrence cannot be withheld. Indeed it is given as a matter of course. In this de- partment of judicial procedure, the law of England ex- hibits a model of excellence, which has been adopted into the law of Scotland in the case of trials for treason only. The institution of the grand jury is at once ad- mirably calculated for restraining groundless accusations, and for remedying the supineness or connivance of tlic public piosecutors. In general, before a party can be put on his trial, the grand jury of the county musljind a bill against him; that is, must declare, on oath, that the evidence brought before them is sufficient to war- rant a trial. This jury consists of twenty-four free- holders, of whom twenty -three only are sworn in. "To find a bill, there must at least twelve of the jury agree : for, so tender is the law of England of the lives of the subjects, that no man can be convicted at the suit of tlie king, of any capital offence, unless by the unanimous voice of twenty -four of his equals and neighbours; that is, by twelve at tlie least of the grand jury, ill the first place assenting to the accusation; and afterwards by tlie whole petit jury, of twelve more, finding him guilty upon his trial." (/J/ffrA-«/one'« Commcntaries,hook\\ . c. 23.) Prosecutions for crimes, not capital, may be commenced without the previous authority of the grand jury, by way oi information, in the name of the king. These are of two kinds ; first, those which are properly the king's own suits, and filed ex officio by the attorney-general ; " secondly, tliose in which, though the king is the no- minal prosecutor, yet it is at the relation of some pri- vate person, or common informer," (Blackstone) ; but it is provided, by slat. 4th and 5th of VVilli^iand Mary, c. 18. that no information shall be filed witTiout express direction from the Court of King's Bench. Appeal at the suit of private parties, a form now almost in desue- tude, is another mode of accusation not requiring the sanction of a grand jury. It is competent, in cases of larceny, rape, arson (fire raising) and mayhem (maiming) to the party injured ; and, in cases of murder, to tlie near relations of the defiuict. Impeachment by the com- mons of Great Britain in Parliament assembled, is an- other form by which persons suspected of high crimes and misdemeanoiu's are brought to trial. — Whatever be the form of the accusation, the mild spirit of British justice presumes the party accused to be innocent, till he is actually convicted. Yet the rigour with which prisoners are confined is frequently much greater tharv the purpose of sure custody seems to require. In gene- ral, it may be remarked, that the use of irons, as a securi- ty against escape from prison, is precisely a substitution of a cheap but inhuman mode of restraint, for the pro- per degree of strength in the structure, or for the pro- per number of guards. Were prisons properly con- structed and guarded, there would be no necessity for punishing, with irons, persons whom, till conviction, the law holds to be innocent. But a practice, still more ad- verse to this legal presumption, prevails in England. Prisoners in irons are brought into court, and placed at the bar ; though it must be obvious, that, in the very face of the highest power which the taw exerts, and in ACE ACE 91 the midst of a crowded assembly, tlierc can be no risk of escape. In still another i-espcct, the innocence of the party accused, even when it no longer rests upon pre- sumption, but is ascertained by acquittal, is not followed by, what ought to be a consequence of acquittal, indem- nihcation for the loss and expense which the party has incurred. While a party, who has been successful in a civil action, obtains indemnitication for the sums which he has expended in maintaining his right, it seems some- what inconsistent that a party in a crhninal action should receive no indemnification for the sums which he has expended in defence of his character, liberty, and life. That criminal prosecutions arc carried on for the benefit of the /lublic, is no sufficient answer. When the interest of an individual suffers any detriment for the benefit of the community, reparation ought always to be made. Indeed, when firojierty is taken from an individual, for any public purpose, such as a high road or a canal, the person so deprived always receives an equivalent ; and why ought not this principle of compensation to be ex- tended to him who, in the course of public justice, has been erroneously subjected to a temporary loss of li- berty, most probably to an irretrievable loss of health and character ; and, what is worse, to those tempta- tions which extreme indigence, and loss of reputation, render almost irresistible ? In matters of this kind, that is a very narrow policy which would lay much stress on the exjxense oi doing justice. Justice is, in all cases, true policy, (a) ACCUSATIVE, the fourth case of Latin nouns, which, like the dative case, denotes the apposition or the junction of one thing to another. This apposition may take place either in consequence of previous mo- tion, or without it; and hence we see tlie reason why the accusative case is put after an active verb ; for the action is supposed to proceed from the agent to the thing acted upon. A different account of this case hasT)een given by Mr Harris in his Hermes, p 283.

It was afterwards applied to such of the followers of Peter Mongus, who in 482 deserted him, when he subscribed to the decrees of the council of Chalcedon. The Ace- phali were generally Eutychians, and were divided into the C'lrrufiticols, tlie IncorrufiticoU, the Agnoetx, and the Tritheitx. The Corrupticolse, who were the adhe- rents of Severus of Antioch, maintained that our Savi- our's body was corruptible before its resurrection ; while the Incorrupticolae held the opposite opinion.

A similar custom prevails among the Chinese. In a room hung round with mourning, they raise an altar, on which is placed an image of the deceased, and every one who approaches it, bows four times, and offers gifts and per- fumes. The erection of accrrae was prohibited by the laws of the twelve tables. Acerra was likewise used as synonymous with Ihii- ribulum and /lyjcis, to signify the small pot or censer, which contained the incense and perfumes that were burnt on the altars of the gods. Votaries offered differ- ent quantities of incense, according to their rank and opulence ; hence the rich were said to sacrifice /ilena acerra, pouring out their incense, trom full censers on the altar; while the poor, who used no censers, pre- sented their humble offerings with their fingers.

Achaeus afterwards recovered possession of Thessaly ; but having committed the crime of man- slaughter, was obliged to fly to Laconia, a province of Peloponnesus, where he died, and where his posterity remained under the appellation of Achxans, till they were expelled by the Uores and fleraclidse. They then laid claim to Aci.aia ; and having driven out the lonians, took possession ol the country, under the con- duct of their brave king Tisamenes, the son of Orestes. The kingdom consisted, as during the time of the lonians, chiefly of twelve cities, which were divided be- tween the four sons of Tisamenes, who, with their cou- sin, a grandson of Orestes, for some time jointly reign- ed over this new Achaean state. At length the torm of government was changed and a mixed democracy es- tablished. Their territory was not extensive, nor their revenues large; but the inhabitants, though without commerce, or greater industry than was necessary to pro- cure subsistence, were governed by wise and equal laws. Thus united, thyr cities or states formed only one body ; and few causes of envy or objects of ambi- tion existing among them, political harmony pervaded every class of the citizens. So celebrated were their magistrates for probity, justice, and love of liberty, that Ihey were at one time. the common arbitrators of the Italian Greeks. After the battle of Leuctra, they were chosen umpires in the dispute between the Lacedaemo- nians and the Thebans, who respectively claimed the victory, and their decision was submitted to as impartial and just. They retained their liberty and republican formof government, till the time of Alexander the Great ; after whose death, they became a prey to political dis- cord, and were oppressed and enslaved, sometimes by the Macedonian kings, and sometimes by tyrants of their own. Each town attentive to its own interest only, be- gan to separate from the rest ; mutual jealousies ensued ; and the common cause of liberty completely languish- ed. But the invasion of Italy by Pyrrhus about the 125th Olympiad, B. C. 280, again united the Achseans, and led them not only to revive their ancient league, but to extend its influence, by receiving other states into the union, till at length it embraced the whole of Greece, except the territory of the Lacedaemonians. By the Achaean league, all the cities subject to it were govern- ed by a great council or general assembly, consisting of a certain number of deputies from each of them, elect- ed by a plurality of votes. It was convened ordinarily twice a year, for the purpose of enacting laws, filling vacancies in the magistracy, declaring war, concluding peace, or forming alliances ; and its decisions were binding on all the members of the confederacy. This assembly had at firsttwo presidents, or chief magistrates, iioininaiud alteriiutely by the different states; but tliey Soon elected only one, who presided in the council, aud commanded the army. They and the other magistrates continued in office two years successively ; and the pre- sident, called Ktrati-gon by the Greeks, and firator by the Latins, was responsible to the general assembly. The demiurgi, ten in number, next in authority to the praetor, were chosen by the assenibly, apiiointed to act as the privy council ol the praetor, and had the power, on some extraordinary occasions, of summoning the general assembly. Such was the fundamental constitu- tion of the Achaean confederacy. But their peace and prosperity were not of long continuance. Tne rivalry and power of the Lacedaenionian.. first reduced them to the necessity of applying for assistance to the sovereigns of Macedon ; and being afterwards overpowered by the jEtolians, they formed an alliance with Philip, who hav- ing successfully supported them against their enemies, re-established their tranquillity, by procurmg a general peace. Refusing, however, to aid his ambitious pro- jects, Philip soon changed his conduct towards them, and even poisoned Aratus, whilst he was praetor for the seventeenth time. Under the presidency of Philopce- men, during the war between Philip and the Romans, about 200 years B. C. the Achseans entered into an al- liance with the latter, and at the conclusion of the war, were put in possession of Corinth, delivered from every kind of servitude, and again permitted to govern them- selves by their own laws. In the year B. C. 191, the powerful city of Lacedaemon was added by conquest to the Achaean commonwealth, by which means the Achse- ans eclipsed all the other states of Greece. But inter- nal disputes about the place of holding their general assemblies, and the turbulent spirit of the Lacedaemo- nians, soon interrupted their tranquillity. The Achaean league was at this time courted by almost all the Eastern nations : its ancient alliances were renewed ; and its in- creasing power became an object of jealousy to the Ro- mans. The death of Philopoemen, who was poisoned by the Messenians, after they had defeated him, and taken him prisoner, gave a blow to the interest of his countiy, from which it never completely recovered. The Achjean confederacy becamf feeble by being disunited ; and in the year before Christ 147, the Romans, who had some time before interfered with its internal policv, decreed, that a great number of the confederate cities should be separated from the general alliance, and in future be governed by their own laws. This, indeed, roused their indignation, and gave a new spring to their exertions ; but their struggle in the war with the Romans which succeeded, was ineffectual. No longer directed by wise magistrates, or skilful commanders, their spirit of re- venge, though ungovernable and savage, could be of no avail against the military talents of the Romans. Ac- cordingly in 146 B. C. Mummius, the Roman general, arrived in Greece, defeated the Achaeans, plundered Co- rinth of its rich spoils, and then reduced it to ashes ; under the ruins of which, the Achxan league seems to have been buried. It was soon after dissolved, and Greece reduced to a Roman province under the name of Achaia, which paid an annual tribute to Rome, and was governed like the other conquered provinces of the empire. During the reign of Nero, it was restored to its ancient liberty ; but it was afterwards reduced to its former state of subjection by Vespasian. Its privileges were in some degree enlarged by Nerva, though it was still governed by a Roman prxior ; and in this state it ACH ACIl 93 reniaiiietl till the time ol Constantino the Great, who, in his new division oi the Roman pioviiuu-s, snbjeetcd it to the praefect of Ihyricum.

The em- pire experienced much vicissitude of fortune during liis reign. Tiiough capable of forming bold and extensive plans, he warned steadiness to execute them; and was so devoted to sensual pleasures and field sports, as to neglect, in a great measure, those military preparations, which the state of the kingdom required. The Asiatic rebels, supported by the Persians, besieged and took the city of Bagdad, to recover which, all his efforts were ineffectual. In Ti-ansylvania and Hungary, though assisted by the famous Bcthlem Gabor, aiul Potskay, the success of the Turks against the Germans was not much greater: yet a peace was at length concluded be- tween him and the emperor, without any material dis- advantage to either. Peace was likewise restored with the Persians before his death; but his reign continued to be disturbed by Insurrections, and his personal safety- was endangered by a pretender to his throne, and seve- ral attempts upon his life. His seraglio consisted of 3000 women; and he kept 40,000 falconers, and almost as many huntsmen, in various parts of the country. He expended large sums in building, particularly on a mag- nificent mosque in the Hippodi'ome. Though ignorant, proud, and ambitious, he was less cruel than many of his predecessors : and though naturally of a strong constitu- tion, he died at the age of twenty-nine. His three sons successively reigned after him. (rf) ACHMET II. emperor of the Turks, was the son of sultan Ibrahim, and succeeded his brother Solyman in 1691. Durhig his reign, the administration of govern- ment was feeble, and the wars of the empire were con- ducted with little vigour or success. The Germans, the Venetians, and the Arabs, made considerable encroach- ments on the limits of the empire, which he never was able to repel. His character in private life was amiable and inoffensive, and his conduct in civil affairs lionourable and just; but as a sovereign, he was destitute of the ta- lents which are necessary for the government of a power- ful and extensive empire. He had some taste for poetry and music, and was universally esteemed and beloved as a man. He died iji 1695, at the age of fifty, (rf) ACHMET HI. emperor of the Turks, son of Maho- met IV. on the deposition of his brother, Mustapha II. in 1703, ascended the imperial throne. After subduing the insurrections which had for some years weakened the government, his great object was to amass wealth; and with this view, he debased the coin, and imposed new taxes. He gave protection to Charles XII. of Swe- den, who took refuge In his dominions after the battle of Pultowa; received him with great hospitality ; and at the instigationof the sultana mother, declared war against the Russians ; which was soon terminated by the ad- vantageous peace of Pruth. He likewise made war on the Venetians, and recovered the Morea from them ; but in an attack on Hungary, his army was defeated by prince Eugene in 1716 at the battle of Peterwardin. By sub- mitting implicitly to the influence of his ministers and favourites, he lost the confidence of the people, and tar- nished the glory of his otherwise splendid but short reign. In 1730, he was driven from his throne by the sedition and rebellion of his soldiers. After his de- thronement, he was confined in the same apartment which had been occupied by his successor Mahomet V. and continued there till he was cut offby an apoplexy, at the age of 74, in the year 1736. (c/) ACHMIM, or Ec HMiM, a considerable town in Upper Egypt, situated on the eastern bank of the Nile. It was called by the ancients Chemnus. or Chcmtno, and Panq- 96 ACII ACIl Jitis: its Coptic name is Smin. Abillfedu describes Achmimas a large town containing atenipe, whicli may be compared witli the most celebrated inonuiiients of antiquity, constructed of piocligious stones, wliich arc sculptured with innumerable nj^ures. Tnougn still one of the finest towns in Upper Kgypt, its extent is greatly circumscribed, and its beauty much impaired. When visited by M. havary, the ruins of the temple were with- out the compass of the town ; some of tuc stones had been transferred into a mosque, where tney were placed without taste or regularity; and others lay in coalused heaps in the streets of Achmim. A few still remained, whose size rendered them immoveable. Among the figures with which they were covered, the most remark- able were four concentric circles inscribed in a square ; the innermost circle contained a figure of the sun; ol the two next, which were botli divided into twelve parts, one exhibited twelve birds; the other, twelve animals almost effaced, apparently the signs of the Zodiac ; in the fourth, were represented twelve human figures, which M. Savary, with much probabi.ity, supposed to have been the twelve gods, designed as emblems ot the twelve months; for the Egyptians were the first who thus divided the year. The four seasons occupy the angles of the square ; and a globe, with wings, is still discernible on its side. It is probable, that the temple was dedicated to the Sun, and that the hieroglyphics on this stone represented his passage into the different signs of the Zodiac, and his annual revolution in the hea- vens. They may be regarded as an unequivocal proof, that the Egyptians possessed, from the remotest antiqui- ty, a considerable knowledge of astronomy. At Achmim, there is a Hospice, or convent of Franciscans, established for the entertainment of the converts or persecuted Christians in Nubia. South of the convent, at the dis- tance of some hundred yards, there is a triumphal arch built by the emperor Nero, with the inscription HANI ©EJi. The streets of this town are wide and clean, and its police is well regulated ; but the air is tainted by a calish of stagnant water, and the inhabitants are yellow and un- healthy- The women retain no marks of beauty after childhood ; at sixteen, they are beyond the age of mar- riage ; and INIr Bruce saw several of them pregnant, vho were not eleven years old. Yet the men are neither smaller, nor less active and vigorous, than in other places. Achmim has extensive manufactures of cotton cloth, and pottery; and its crops, particulariy of wheat, are supe- rior to any in Egypt. But the most remarkable object in this place, is the serpent Haridi, which is the won- der of all the surrounding country. It is now about a century since Scheick Haridi died here, and the Maho- metans, who revered hiin as a saint, erected a splendid monument to his memory. An artful priest, availing himself of the general veneration for Haridi's sanctity, pretended that his soul had passed into one of those in- nocuous serpents, with which the Thcbaid abounds. He trained it with great care ; taught it to perform innume- rable tricks; and, confining it to the tomb of the saint whom it represented, undertook, with this sacred as- sistant, to cure every species of disease. Crowds of pa- tients resorted to it from all quarters; a few fortunate cures, effected by nature or imagination, established its credit; successive priests were intrusted with the charge of this wonderful serpent, and to the persuasion of its healing power, had soon the address to add the belief of its immortality. They cut it in pieces in presence of the emir; put it into an urn, where they allowed it to conilnLC for two hours; and then produced a serpent, which could not be distinguislied from the lornier in size or appearance. Such an irresistible prool of us di- vinity necessarily established its claim to adoration, and gi eatly enhanced the value of its favours. Wiien pro- pitious to its supplicants, it appeared at the bottom of the lomb ; but soon became so shy, that it was seen only by those who presented the richest offerings. In extra- ordinary cases, when its presence was indispensable to the cure of a patimit, a young virgin was sent to solicit its aid. The damsel suffered the serpent to twi.e around her, and carried it in triumph to her afiiiclcd relation, whose recovery was now regarded as certain. Even the Christians acknowledge the power ol the serpent Hari- di; but tliey maintain, that it is the demon Asmodeus, who slew the seven husbands of Tobit's wife ; and that the angel Raphael, after metamorpnoshig him, conveyed him to Aciniiim, where God allocs him to perform won- ders for the purpose of deceiving the infidels. Accord- ing to M. Savary, this serpent is of the kind described by Herodotus, which were held sacred by the ancient Egyptians. They were called al'cchi iaiu-om, i^ood genii, and were emblems of Cnt-Jih, the symbolical divinity which represented the Divine bounty.

The name achro- maiic, from a priv. and xfia/ta, cylour, \n.& given by Dr Bevis to those telescopes whose object glasses are com- posed of two or more lenses of different substances, for the purpose of removing the chromatic and spherical aberration. It appeared from Newton's experiments on light, that the refraction of the differently coloured rays, which compose the prismatic spectrum, was always in a given proportion to the refraction of the mean re- frangible ray; that refraction could not be produced without colour; and therefore, that no improvement could be expected m the refracting telescope. New- ton's Optics, b. ii. exp. 8. But though Newton could scarcely refuse his assent to these conclusions, which were fairly deducible from his experiments, he was too cautious a philosopher to maintain, that the imperfec- tions of the refracting telescope, arising from the aber- ration of colour, were absolutely incapable of correc- tion. He remarks, on the contrary, in his sixth letter to Oldenburgh, that "it did not seem to him impossible for contrary refractions so to correct each other's in- equalities, as to make their difference regular; that, for this purpose, he examined what may be done, not only bv glasses alone, but more especially by a com/ili- cation of driiers successive mecliu/ns, as by two or more glasses, or crystals, with water, or some other fluid be- tween them, all which together may perform the office of the object-glass, on whose construction the perfec- tion of the instrument chiefly depends ; and that the re- sults of these trials, as well as the results of theory, would probably be given on some future occasion." ACimOMATlC TELESCOPES. 97 From these observations, it is very obvious that Newton was far iVoin despairing of the improvement of dioptric instruments; and that his capacious mind, even in some measure, anticipated the discovery of the achromatic telescope. The first suggestion which led the way to this great discover)', has been attributed, by foreign mathemati- cians, to the celebrated Euler. In the Memoirs of the Berlin Academy, this philosopher observes, that New- ton appeared to have no idea of correcting the chromatic aberration by a combination of lenses of water and glass, but that the union of transparent substances in the hu- man eye, whicii he conceived to produce a perfect image, suggested to himself the great probability, that a similar combination might form an achromatic object-glass. See ]\lc7n. Berlin, 1747, torn. iii. p. 279. Euler therefore proceeded to determine the dimen- sions of the lenses, which, when combined with water, would produce a colourless image ; and he has comput- ed a table, containing the radii of curvature for all focal lengths, from one inch to 33 feet. The instruments, however, which were executed at Paris on this princi- ple, were found to be little better than the common re- fracting telescope. From this view of the labours of Euler, it clearly ap- pears, that he was unacquainted with Newton's letter to Oldenburgh ; that he proceeded on a false principle, viz. the perfect achromatism of the human eye ; and that he has not given a shigle hint that was not known to New- ton about eighty-five years before. But though the memoir of Euler is not intitled to the praise of ori- ginality, it had the great merit of exciting the inquiries of philosophers, respecting this long neglected subject. The attention of Mr John Dollond was, at this time, directed to the investigations of Euler; and as he per- ceived that the results obtained by the German philoso- pher contradicted the experiments of Newton, he re- traced the calculations of the former ; he substituted the tiumbers which express the ratio between the refractive powers of glass and water, as deduced from the experi- ments of Newton, instead of the hypothetical numbers of Euler, and found, that, even upon his own principles, there could be no correction of the chromatic aberra- tion, unless when the focal length of the compound lens was infinitely great. Dollond therefore remained in the conviction, that the experiments of Nevrton were cor- rect, and that refraction could not be produced without colour. See Phil. Trans. 1752. To these objections Euler replied, in the Berlin Me- moirs for 1733. Without questioning the accuracy of Newton, he maintained, that the quantities in his for- mulae, objected to by Dollond, were too minute to inva- lidate his theory ; he endeavoured to point out some inconsistencies in the calculations of Dollond, and, re- suming his erroneous analogy betv/et-n the organ of vi- sion and his proposed telescope, he insisted, that every objection to his theory v.'ould be finally removed. The researches of Euler were carefully examined by M. Klingcnstienia, a Swedish philosopher, who began to suspect the accuracy of Newton's eighth experiment, and therefore determined to repeat it. By making the rays pass throitgh a prism of glass placed within a pris- matic vessel of water, Nev.ton found, that, when the emergent ray was parallel to the incident ray, it was perfectly white ; and that, when inclined to the incident ray, its edges were tinged with colours. But in the experiment of Klingenslierna, the emergent light was Vol. I. Part I. actually coloured, even when it emerged parallel to the incident ray. See S'n'ri/. ylb/ian(Uunf;i->!. vol. xvi. p. 300. The paper, which contained this experiment, was transmitted to Mr Dollond by its author, in October 1754, who assailed the experiment of Newton, both by geometrical and metaphysical reasoning. The former convictions of the English optician were immediately unsettled, and he dctemiined to resort to the infallible evidence of experiment. In a prism of water, formed by two pieces of plate glass, he placed a glass prism, with their refracting angles in opposite directions, and adjusted the angles in such a manner, that the emer- gent and incident rays were parallel. When the appa- ratus was thus adjusted, the emergent light was infected with the prismatic colours; — a result similar to that which was obtained by M. Klingensticrna, but contrary to the eighth experiment of Newton. As Mr Dollond was thus able to produce colour without refraction, he saw, that, if the angle of the water prism could have been sufficiently enlarged, he might have produced consider- able refraction without colour. He therefore used a glass prism with an angle of only 9°, and increased the angle of the water prism, till the emergent light was free from colour. In this situation of the prisms, the refrac- tion by the water prism was to that of the glass prism as 5 to 4. The emergent ray was therefore inclined to the incident ray ; refraction was produced without co- lour ; and therefore the refraction of the different colour- ed rays was not in any given ratio to the mean refrac- tion. The success of these experiments naturally led Mf Dollond to expect, that the same result might be ob- tained by combining prisms of different kinds of glass. A considerable time, however, elapsed before this ex- periment was made, and it was not till the end of 1757 that it was successfully executed. Mr Dollond then found, that, of all the kinds of glass which he tried, crotvn g-ki.is pi'oduced the least divergency, or dispersion of the different rays, and flint glass the greatest; and that, if a prism of flint glass were cojubined with a. prism of crown glass, with their refracting angles in an opposite direction, and so proportioned to each other, that the refraction produced by the flint glass prisin was to that produced by the crown glass prism, as 2 to 3, the incident light would emerge after refraction, with- out divergence, or dispersion, of the rays. When this result was obtained, the step to the inven- tion of the achromatic telescope was comparatively easy. A lens may be conceived as composed of an in- finite number of small prisms with different refracting angles ; and therefore it might naturally be supposed, that an object glass, composed of a convex lens ot crown glass, and a concave lens of flint glass, with the radii of > curvature properly adjusted, would produce an image perfectly free from chromatic aberration. Mr Dollond accordingly constructed telescopes with these object- glasses, wiiich were much superior to those of the com- mon construction, and received the name of Achromatic Telescopes. Before we proceed to detail the future history of this useful instrument, we must pause to consider a claim to the invention, which has been urged in behalf of Ches- ter More Hall, Esq. of Morehall, in Essex. It has been positively stated, that this gentleman, so early as 1729, considered the eye as an achromatic instrument, and supposed, that, by a similar combination of different sub- stances, an object might be formed, so as to produce a N 98 AC HROM ATIC TE LESCOPES. colourless image. After many trials with (liffercnt kinds' of glass, he is said to have constructed, so early as 1733, several achromatic object-glasses, whicli, with a focal length of 20 inches, bore an aperture of more than two inches and a half. One of these telescopes is stated to be in the possession oi the Rev. Mr Smith, of Chai- lotte-street, Rathbone Place, and to possess all the pro- perties of DoUond's telescopes ; and another came into the hands of Mr Ayscough, optician, in Ludgate Mill, so early as 1754. These facts are mentioned in the Gen- tleman's Magazine for 1790, p. 890, by an anonymous author ; and, if properly authenticated, are suBicient to prove, that Mr Hall was the original inventor of the achromatic telescope. But though we make this admis- sion, we cannot pass unnoticed the remark in that anony- mous paper, that Mr Hall's invention seems to have been made public by Mr Bass, the optician who ground his lenses ; because it is evidently intended to insinuate, that Mr DoUond had availed himself of information ob- tained, either directly or indirectly, from Mr Bass. Now, whatever evidence can be adduced in support of Mr Hall's claims, there is the strongest reason to be- lieve, that Dollond did not receive the least hint of the invention. We find his attention directed to the sub- ject, in consequence of Euler's researches ; and we see the discovery gradually unfolding itself in his mind dur- ing the vast interval between the first suggestion of Klingcnstierna and the final construction of the achro- matic telescope. We have therefore no difficulty in set- tling the various claims, which have been urged by our own countrymen and by foreigners, for the honour of this invention. — By his experiments on light and col- ours, Sir Isaac Newton pointed out the cause of the im- perfections of the dioptric telescope. He made experi- ments on compound object-glasses of water and glass, with a view of removing these imperfections ; and though his attempts were unsuccessful, yet he did not despair that this great object might be accomplished. Euler, without being acquainted with these attempts of New- ton, niadc similar experiments with lenses of glass and water; but was more sanguine in his hopes of success than the English philosopher. Klingcnstierna had the high merit of making the first step to the discovei-y, by showing the error in Newton's eighth experiment, and proving, that, with prisms of glass and vyater, there could be colour without refraction. This idea was seized by Mr Dollond, who traced it through all its consequences, till he arrived at the construction of the achromatic telescope. If the claims of Mr Hall are substantiated by unexceptional evidence, we cannot withhold from him the merit of being the original inventor. But while we allow, that he may have anticipated Dollond in the discovery, we must, at the same time, guard against every insinuation that has the least tendency to tarnish the fame of that ingenious optician. As soon as the discovery of Dollond was made public, the foreign mathematicians employed all the resources of the modern analysis to ascertain the curvature which mvist be given to the lenses, in order to correct, at the same time, the aberration of colour and sphericity. The genius of Clairaut, Euler, and D'Alcmbert, were first called into action, and produced the most elegant solu- tions of this interesting problem. The subject was al- so investigated by Klingcnstierna, Rochon, Boscovich, Pezenas, Duval le Roi, Jeaurat, and Klugcl ; and the practical optician has received, fromtlie labours of these philosophers, all the assistance which art can expect from science. Durhig all these investigations, the common theory of refraction, as established by the experiments of Newton, was never called in question. It wastheretore reserved for our ingenious countr)'man, Dr Robert Blair, Profes- sor of Practical Astronomy in the University ol Edin- burgh, to throw new light upon this branch of physics. The discoveries of this philosopher were equally impor- tant and unexpected, and intitle him to a high rank among those illustrious men, wiio have contributed to the advancemerit of the science of optics. From a num- ber of well-conducted experiments, Dr Blair has shown, that a great variety of fluids possess the quality of dis- persing the rays of light in a greater degree than crown glass ; and that this quality is possessed in a remarkable manner by the solutions of metals, the essential oils, and all the mineral acids, excepting the sulphuric. He has shown, that the superior refrangibility of the violet to the red rays, when the refraction is made from any medium into a vacuum, may be considered as a general fact ; yet, when the refraction is made from one medium into ano- ther, the red rays are sometimes the most refrangible, and the violet rays the least refrangible ; and sometimes all the coloured rays in the spectrum are eqiialiy re- frangible, according to the qualities of the media through which the light is transmitted. By making trials witJi object-glasses composed of two media of difl'erent dis- persive powers, in which both the chromatic and spheri- cal aberrations were corrected as far as the principles would allow, he found, that the correction of colour is never complete ; for the green rays, which are the mean refrangible in crown glass, were among the least re- frangible in all the refracting media which he had hitherto examined, which is evidently the cause of the uncorrected colour. This circumstance would have ex- tinguished every hope of removing completely the chro- matic aberration ; but Dr Blair had the good fortune to discover, that the muriatic acid was an exception to this general rule. He found, that a fluid, in which the parti- cles of muriatic acid and metalline particles hold a due proportion, had a greater dispersive power tlian crown glass, and, at the same time, refracted all the orders of rays exactly in the same proportion as the crown glass ; and hence he concluded, that rays of all colours, which diverge by the refraction of the crown glass, may cither be made to emerge parallel by a subsequent refraction at the confines of the glass and muriatic acid ; or, by diminishing the refractive density of the fluid, the re- fraction, which takes place in the confines of it in the glass, may be rendered as regular as reflection. Upon this new principle, Dr Blair constructed an object-glass fourteen inches in focal length, composed of crown glass, alcohol, and an essential 6il, which was much superior to an object-glass of crown and flint glass, with 30 inches of focal length, and the same aperture. Having- thus given a brief account of the histoi^ oi the achromatic telescope, we shall now proceed to ex- plain the principles of its construction, beginning witli the achromatic object-glass. Ox Achromatic Object-Glasses. Let AB, CD, EF, be the three lenses which compose an achromatic glass, AB and EF being convex, and of crown glass, and CD being a concave lens of flint glass ; ai\d let us suppose them placed at a little distance from ACimOM ATIC TELESCOP ES 99 each other, that the progvcss of the rays may be more easily observed. II two -while rays of light KL, R'L', moving in parallel directions, fell upon the convex lens AB, at the points L, L', the red rays, which enter into tlieir composition, being the least refrangible, would be bent into the directions Lr,L'/', if there were no other len- ses ; and the violet rays, which are the most refrangible, would be bent into the directions hv, Uv. But when the concave lens CD is interposed, so as to intercept these rays before their convergence at the points v, r, they wili be refracted from the axis, in the directions m /I, n 0, because the focal distance of CD is less than AB ; for, if the lens CD had been made of the same glass, and with the same curvature as AB, the rays would have emerged colourless, and parallel to their original directions RL, R'L' The violet ray ?! o, will cross the red ray at / ; because, on account of its supe- rior refrangibility, it is more bent from the axis by the refraction of the concave lens. The only efl'ect of the greater dispersive power of the flint glass lens CD, is to delay the meeting of the red and violet rays at t. When the third lens EF, intercepts the rays ?n t, n t, before their concourse at t, it will refract them to the same point at F ; for the red rays, which are least re- frangible, fall upon the lens at a greater angle of inci- dence, so that the difference of their refrangibilities is counteracted by their different obliquities of incidence. The rays L'v, L'r, on the opposite side of the axis, will vindergo similar refractions ; so that the differently coloured rays will all meet in the focus F, of the com- bined lenses, and will form an image nearly colour- less. When the object-glass consists only of two lenses, as AB, CD, the focal length of the concave one CD, is ranch greater than that of AB ; from which it happens, that the rays L ?«, L n, are bent towards the axis, and, in consequence of the greater dispersive power of the flint glass, they are united in the focus without colour. The triple object-glasses, however, are preferable to those with only two lenses; for, in the former, the sphe- rical, as well as the chromatic aberration may be cor- rected. It is obvious, that, in order to produce these effects, there must be a certain proportion between the radii of the surfaces n, b ; a', b' ; a", b" . The method of deter- mining these radii by analytical investigation, will be explained in the article Optics. But it may be proper in this place, for the use of the practical optician, to give the results, which are deducible from the researches of the most eminent philosophers. The letters a, b; a', b'; a", b", represent the radii of ciu'vature of the surfaces to which they are affixed in Fig. 5, a being the surface next the object, and b" that next the eye. The letter .r is the focal length of the first lens, whose radii are a, b; y, the focal length of the lens, whose radii are a', b'; and z that of the lens, whose radii are a", b". The focal length of the compound object-glass is always =; 1. Forms for Tri/ite Object-Glasses.

The French opticians use mastich for this purpose. The editor has been favoured with the following forms for achromatic telescopes, by Mr Tulley, optician, at Islington, whose admirable telescopes have received the approbation of the first astronomers and opticians of the present day. They contain the radii of curvature which he actually employs m practice, and which vary only with the density of the flint glass. I.

In order to correct the chromatic aberration in the eye-pieces of telescopes, we are not under the necessity of using compound lenses of difi'erent dispersive powers, as all the orders of rays can be united by a particular arrangement of the eye-glasses. This will be obvious from Plate IV. Fig. 6., where AB is a compound object- glass, and DE an eye-piece, consisting of two lenses D, E. Then if CDE be the axis of the telescope, and PS a ray of white light passing through the object- glass, since the object-glass is achromatic, this ray will fall upon the eye-glass D, without being separated into the prismatic colours, through whatever part of the com- pound lens it is transmitted. This ray, however, will be decomposed after refraction through the lens D, and the red rays will be bent into the direction SR, and the vio- let into the direction SV. But these rays are intercepted by the second lens E, at the points m, n ; and as the re- fracting angle of the lens is greater at m than at ra, this increase of the refracting angle for the red ray will make up for its inferior refrangibility, and the rays S m. S n, will emerge parallel from the lens in the lines vw, nv. The chromatic aberration, therefore, which is always proportional to the angle formed by the rays inr, nv, will be destroyed. In small telescopes and opera-glasses, where it would be very inconvenient to have along eye-piece composed of several lenses, a compound lens of crown and flmt- glass should be used, and may consist either of three or two glasses, with the foUowmg curvatures ; the letters B, b, &c. representing the same radii as before, and F the focal lengtli of the compound lens being = 1 .

If the object is to be erect, as in the Galilean teles- cope, the lens of flint glass must be made convex, and those of crown class concave, in order that the concavity cf the compound glass may predominate. An achromatic eye-piece for astronomical telescopes, of the same kind as that which is represented in Fig. 6. should have the focal length oi the lens D triple that of the lens E, and the distance DE should be double the focal length of E, or two-thirds of the focal length of D. In one of Dollond's best telescopes, the focal length of D was 12.75 lines, and its thickness 1.62 lines ; the focal length of E, 5.45 lines, its thickness 1.25 lines, and the distance between their interior surfaces 4.20 lines : in another eye-piece of Dollond's construction, the focal length of D was 8.30 lines, and its thickness 1.60 ; the focal length of E 3.53,' and its thickness 0.97. In both these eye-pieces, the lenses should be plano-convex, with their plane sides turned to the eye, in order to di- minish the spherical aberration. When the achromatic eye-piece consists of three lenses, it may be constructed by the following formulae, where F is tlie focal length of the object-glass, and .r, y, -, the focal length of the eye-glasses, reckoning from that which is nearest the object. Distance between 1st and 2d lenses .... x-^-y Distances between 2d and 3d ...

Achromatic eye-pieces may be made of four lenses, if their focal lengths are as the numbers 14, 21, 27, 32 ; their distances 23,44, 40; their apertures 5.6; 5.4; 13.5; 2.6; and the aperture of the field bar in the an- terior focus of the 4th eye-glass 7. In one of Ramsden's eye-pieces of four lenses, the focal lengths were 0.77 of an inch; 7.025; 1.01 ; 0.79 ; and their distances 1.18; 1.83; 1.10, reckoning from the lens next the object. This eye-piece was equal to a lens 0.566 inches in focal length. In one of Dollond's best eye-pieces, the focal lengths were 14i lines; 19;22|; 14; the distances 22.48 ; 46.17; 21.45, and the thickness of the lenses at their centre 1.23; 1.25; 1.47. With the intention of enlarging the field of view, Mr Dollond constructed some eye-pieces, consisting of five, and some even of six lenses ; but the limits of tliis work will not permit us to enter into any details, respecting 102 ACT ACI their construction.

See Botany, (w) ACIDS arc a class of chemical agents, distinguished by the following common properties : — They have a sour taste, and are the only substances to which this taste belongs; they arc more or less soluble in water; they change the blue, purple, and green colours of vegetables to a red ; combine with alkalis and earths, neutralizing their common properties ; and dissolve metals and me- tallic oxides. These properties are possessed by the different acids in very different degrees. In some of them, the sour taste is scarcely perceptible in their most concentrated state ; in others, it is extremely strong, even when they are largely diluted with water : and a similar diversity exists with regard to all their other characteristic properties. In general, they exert ener- getic chemical actions, partly from tiie facility with which they afib'-d oxygen to bodies, and partly from the pow- erful affinities they directly exert; and the history of their properties and combinations constitutes the most extensive department of the science of chemistry. The important truth, that oxygen is the principle of acidity, was established by the researches of Lavoisier, and formed one of the leading propositions of the mo- dern chemical system, which he contributed to rear. By a very ample induction, this eminent chemist demon- strated, that the greater number of simple inflammable substances, when combined with oxygen, in certain pro- portions, form compounds possessed of acid powers ; and again, by decomposing a number of acids, he proved, that oxygen exists in them as a constituent principle. He hence inferred, that oxygen is essential to their com- position, and is the principle of acidity.* * This, however regarded as a just induction during the meridian splendour of the antiphlogistic theory, bids fair to become equally objectionable with its previously flourishing antagonist. By neither the phlogistic, nor antiphlogistic theory separately, can the various facts of chemical science be completely explained ; and the numerous discoveries, of late brought to light by the agency of galvanism, tend strongly to evince, that a just view of the subject can only be derived from the united strength of both doctrines. It is true, Lavoisier demon- strated that the greater number of inflammable substan- ces foiTned acids by combination with oxygen ; but it is equally true, that many of those substances, then deemed siin/i/e, are now shown to be compounds, of which hy- drogen forms a part. The doctrine of Lavoisier therefore totters at its base; and if the foundation be erroneous, the superstructure cannot be correct. It is incumbent on those who still maintain inviolable this supposed sole principle of acidity, to show what becomes of the other constituents of those bodies thus acidified. If it is still retained, it most probably must produce some influence on the change resulting ; and that it is retained, is ren- Thcre existed, even at the period of Lavoisier's re- searches, some objection to this conclusion.

Sec Botany, (w) ACOSTA, Uriel, a native of Portugal, whose life exhibits a melancholy picture of the consequences of un- settled opinions, and the cruelty of intolerance. Acosta was born towards the close of the sixteenth century, and educated in the Roman Catholic religion. As he ad- vanced in years, however, he began to doubt the truth of its doctrines; and, on making a comparison between Christianity and Judaism, he preferred the latter, and determined to embrace it. Dreading, however, the in- tolerance of the Catholics, he relincjuished an office of some emolument in Portugal, and persuaded the sur- viving members of his own family to forsake their native countiy, and accompany him to Amsterdam. Here he underwent circumcision, and was admitted to the syna- gogue ; but having soon discovered, that the practices of the Jews were inconsistent with his opinions, he refused to comply with them, and was therefore excommuni- cated. He immediately became the object of persecu- tion, was reviled as an atheist, and was even exposed to the insults of the children in the streets. The resent- ment of the i)cople was still farther inflamed against him, on account of a treatise which he wrote on the Saddu- cean principle, denying the resurrection of the dead. For this ofl'ence he was dragged by the Jews before the civd tribunal ; his book was confiscated ; and he was fined a large sum, and imprisoned. Acosta [)rocecded still farther in scepticism, and at length ventured to deny the divine legation of Moses. But his firmness was not equal to his temerity ; for though he had lived no less than fifteen years under a sentence of excomnmnication, he afterwards made a public recantation of his errors in the synagogue, and subscribed the dogmas of the Jewish church. A few days subsequent to this event, he is said to have been accused by his own nephew of neglecting the rites of Judaism. The sentence of ex- communication was again passed, and was attended by the more humiliating disgrace of receiving thirty-nine stripes ; and of being laid on his back at the entrance of the synagogue, that every one might pass over him. We cannot wonder that such aggravated persecution rendered Acosta desperate. He resolved on the des- truction of his principal enemy, but having failed in the attempt, shot himself between the years 1640 and 1650. See Acosta's Exemfilar. Vit. //zimfin. passim; and Lim- borch's Refutation of it. (r) ACOUSMATICI, the name given the disciples of Pythagoras, who had not completed their noviciate of five years, and who were therefore not initiated into the secrets of his philosophy, (to) ' ACOUSTICS. Acoustics, or the science which treats of the nature and laws of sound, has considerable claims upon our attention. The phenomena which it presents ai'e highly interesting ; and the inquiries of philosophers into their causes have been crowned with considerable success. History. Several Important facts concerning sound must have been known at a very early period. The tuning of the lyre, and various other instruments, which are coeval ■with the remotest antiquity, necessarily implies an ac- quaintance with the fact, that as we diminish the length of musical strhigs, or increase their tension, we render their tone more acute. AVe have, however, no reason to believe, that till 500 years before the Christian era, any attempt had been made to discover the relation which subsists between the length of strings producing the various notes of music. About this period, Pytha- goras gave a correct determination of the ratios between various sounds. The account which the ancients give of the mode by which this philosopher discovered these values is evi- dently fabulous, so that we cannot say with certainty how he obtained them ; thougli it was probably by means of some instrument, which, like the monochord, would enable him to increase or diminish at pleasure the effective length of a string. About 200 years subsequent to the time of Pytliago- ras, Aristotle, who seems to have attended to almost every subject, wrote upon the nature of sound. He understood, tliat the number •of vibrations perfoiTned by strings, or by the air in pipes, is inversely as their lengths ; and that sound is transmitted to the ear by similar vibrations conmiunicated to the atmosphere. We are not infoniied on what evidence Aristotle found- ed these doctrines ; but it is likely, from the loose reasonuig, and imperfect analogies with which the an- cients were satisfied in their physical inquiries, that these opinions v/ere merely sagacious conjectures. Such, in Acoustics, was the nan-ow patrimony trans- mitted to us by the ancients ; and even this scanty pit- tance we did not receive till it was too late to be of any material advantage. During the darkness which over- spread the whole literary world,no additions were made to the science of Acoustics, and even the knowledge which the ancients possessed on this subject, was in a great measure lost ; for though the writings of Aristotle had been preserved, they were so completely misunder- stood, as to be of no use. Galileo may therefore be justly said to have (about the year 1600 after Christ) disco- vered anew, what was known to the ancients concerning the nature of sound. He conceived, that sound is mere- ly a vibration of the air ; that the distinction betv/een musical sounds probably consists in the different fre- quency of these vibrations; and that amusical string, by ACOUSTICS. 1U5 performing each of its vibrations in equal times, pre- serves its uniformity of tone. lie considered the whole matter of a musical string as if collected into its middle point ; and demonstrated, that on this supposition its vibrations would be performed in e(|ual times ; whence he concluded, that if the matter be diffused uniformly alon'^ the string, its vibrations will obey the same law. Though the latter part of this reasoning, in which it is inferred that an uniform string vibrates similarly to what it would do if its whole matter were collected into one point, proceeds on an analogy too distant to be by any means conclusive, the labours of Galileo were va- luable, as they led the way to more accurate investiga- tions. In the year 1714, Dr Brook Taylor demonstrated Ga- lileo's theorem, upon the hypothesis of the initial form of a vibrating string being what is called an harmonic airvf ; and he gave a determination of the frequency of vibration in such a curve. By this demonstration, Dr Taylor has an indisputable claim to the honour of being the first who proved the Isochronism of a vibrat- ing string. M. Sauveur had indeed, in the preceding year, attempted to give a solution of the same theorem, but his demonstration Is in all respects erroneous. Dr Taylor was mistaken in supposing, that, whatever may be the initial form of an inflected string, it will, after a few vibrations, assimie the form of an hamionic curve ; and that this is the only curve in whicli isochronous vibrations can be performed, or all the points of a string arrive at its axis at the same time. Yet his determina- tion of the frequency of the vibrations of a string ex- tends to all cases ; as this frequency is the same, what- ever be the initial figure of the string, if it be all situ- ated on the same side of its axis. The limited nature of the solution given by Dr Tay- lor, induced D'Alembert to apply himself to the same question. The result of his labours was given in the Berlin Memoirs for the year 1750. In that volume, D'Alembert has, by the mode of Jiartiat differences, given a solution of this problem, which embraces all the initial forms of a chord, in which the law of continu- ity takes place ; and has shown, that there is an infinite number of curves, different from that discovered by Dr Taylor, each endowed with this property, that all its points arrive simultaneously at its axis. Shortly after, Euler gave another solution, founded on similar prin- ciples, which led him to a construction more general than that which D'Alembert had employed. It was ob- jected to the generality of this construction, first by D'Alembert, and afterwards by La Grange, that the principles on which it is founded necessarily limit its application to those cases In which the initial form of a string is a continued curve. Euler, with a greatness of mind of which we have but few examples, acknowledged the justice of the remarks which the latter of these ma- thematicians had made against the generality of his con- struction. Daniel Bernoulli attempted to extend Dr Taylor's solution to all possible initial forms, by conceiving them to be either harmonic curves, or produced by a combina- tion of several subordinate harmonic curves. This sup- position enabled hun to give a solution of the problem of vibrating strings, equally extensive in its application with those which can be legitimately deduced from the methods of either D'Alembert or Euler. These three mathematicians have equally fliiled in shoving, that their equations extend to all possible cases of a vibrating Vol. I. Part I. chord. To remedy this delect, I>a (irange uncstiga- ted this question by a mode perfectly new, and totally independent of the hypothesis, that the initial form of the vibrating chord is subjected to any law of continu- ity ; and therefore his conclusions nmst be considered as independent of any such law. lie considers a vibrat- ing chord under two views, either as composed of a finite or an infinite number of particles. In the former case, analysis conducts him to a general theory, the same with that which we have mentioned above as invented by Daniel Bernoulli. In the latter case, his conclusions arc exactly the same with those which Euler had drawn from sources not so legitimate. Daniel Bernoulli, subsecjuent to the publication of his essay on vibrating chords, investigated the lateral vibra- tions of an elastic rod fixed at one extremity; and de- termined the vibrations of a column of air contained in a pipe. The conclusions at which he has arrived, have, when brought to the test of experiment, been found ac- curate, though deduced from suppositions which arc not considered as perfectly just. Euler and La Grange have also prosecuted this latter stibject, by methods similar to those which they have employed in the pro- blem of vibrating chords. The vibrations of several other bodies have been considered by both Bernoulli and Euler, and the results of the latter corrected in some instances by Riccati. Sir Isaac Newton was the first who investigated, with any precision, the propagation of sound. His reason- ings on this subject were always considered as extreme- ly difficult and obscure, and have been shown, first by M. Cramer, and afterwards more fully by La Grange, to be in some respects faulty ; but by that good fortune which attended him In all his researches, his conclu- sions are accurate, and have been confirmed by the in- quiries of subsequent philosophers. Several other mathematicians attempted this subject with no better success than had attended the efforts of sir Isaac Newton ; their methods being founded on such erroneous principles, or their calculations being so embarrassed with infinite series, as to remove all confidence in their conclusions. At length, about the year 1759, both La Grange and Euler succeeded in giving solutions of this problem, unobjectionable in their principles, and extensive in their application ; thus subjecting to analysis a problem in- volved in such difficulties, as seemed to place it wholly above the reach of mathematical investigation. One circumstance, however, rendered the labours of these philosophers not quite satisfactory. The velocity which theory uniformly attributes to sound, is found to differ considerably from experience. The cause of this difference La Place has lately suggested to be an increase in the elasticity of the air, produced by the heat evolved during the condensation to which it Is sub- jected in transmitting an imdulation. Biot has examined what Increase of elasticity would be required to render theory consistent with obsena- tion ; and has found it to differ very little from what should take place agreeably to the experiments of Mr Dalton on air, removing by this result the chief dif- ficulty in the theory of sound. The science of Acoustics is indebted to several other philosophers, who have laboured in the experimental de- partment of this science. About the year 1654, Soland made the first speaking trumpet from the description given by Kircher, of the O 106 ACOUSTICS. lube which Alexander was supposed to have used in commanding his armies. Moreland, however, by draw- ing the attention ol philosophers to that which he con- btructed in 1671, had the merit ol" being the first who made this instrument really known, and applied to use. Dr Wall is about the same time discovered the fact, that il a string be made to sound near another which corresponds to it in thickness and tension, but of which the length is any multiple of it, the latter will divide itself into several vibrating portions, each equal in length to the fonner string, and sounding the same note with it. He also discovered, that, when a string is divided by any slight pressure into two portions, commensura- ble with each other, the vibrations excited in one of these portions will communicate itself to the other. The grave harmonics produced by the union of two sounds, were observed about the year 1753, by both Tartini and Romieu. Lambert, by his experiments on flutes; DrChladni, by his mode of observing the vibrations of plates, and his discovery of the longitudinal and spiral vibrations of solid bodies ; Dr Thomas Young, by his observations on the rotatory motions of strings ; and Dr Robison, by his remarks on the production of continued sounds by dis- tinct independent noises, the induction of harmonics on a vibrating chord, and the transmission of sound through water — have extended our experimental knowledge on this subject, and corrected our theoretical deductions by the accurate test of experience. By the labours of these philosophers, Acoustics has been brought to a state of great perfection. The science now presents a very different aspect from what it ex- hibited in the time of the ancients. The properties by which bodies act in producing sound, arc now known j and their mode of operation has, in general, been suc- cessfully investigated ; — the laws which sound obeys u» its transmission to the organ of hearing, have been re- duced to the common principles of mechanics ; — tl)e essential differences between various sounds have been detected ; and their mode of action upon the ear is pretty well understood : thus affording us a more com- plete knowledge concerning sound, and the sense of hearing, than we possess with respect to any other of our senses or their objects. These improvements we chiefly owe to the exquisite refinements in modern mathematics, and to the spirit of experimental philosophy, which has diffused itself over Euiope since the thne of Bacon. The different sciences are united by so many points of contact, that we can hardly promote any one of them, without at the same time advancing several others. The mode of partial differences was chiefly suggested to D'Alembert, by his inquiries concerning a vibrating string ; and it is by the application of it which he has given during the course of tliese inquiries, that Euler was enabled to erect a superstructure, which has in a manner made the discovery entirely his own, and almost wholly changed the appearance of fluxions. The researches into the nature ol sound have also illumined several collateral branches of pt.ysical know- ledge. By tliem we have acquired more accurate views of the real motions which take place in nature ; and the facts which have been discovered concerning sound, afford valuable hints to the theorist, both in physics and physiology, and promise to form a powerful in- strument of research in the hands of the experimental philosopher. PART I. THEORY OF ACOUSTICS. CHAP. I. Of the Production of Sound in General. If we rub our moistened finger along the edge of a drinking glass, or draw a bow aci'oss the strings of a violin, we can in both cases procure sounds which re- main undiminished in intensity, as long as the operation by which they are excited is continued. A similar fact takes place with respect to any other sonorous body, whose structure is not destroyed by the mode of excita- tion employed. When therefore the sound of a body becomes by any means extinguished, we are not to at- tribute this extinction to the capability of the body for producing sound being exhausted, but rather to the dis- continuance of that mode of action by which the excited body had formerly produced sound. Though all bodies may, by some mode of excitation, be made to sound, there is a great difference among them in the intensity of the sounds which they produce during the operation, and in the permanence of these sounds after the excitation has ceased. Thus, if we strike two bells, one of lead, and the other of brass, the sound of the former is feeble and momentary, compared with that of the latter. In the former, therefore, ac- cording to the remark which we have made above, that action, by which the body produces sound, is excited only in a small degree, and ceases with the excitement ; in the latter there is some power, by which, wlien this mode of action is once begun, it perseveres in it for some time afterwards. By examining the characteristic difference between these two classes of bodies, we may be enabled to discover what are the physical properties on which the production of sound depends, and what is their mode of action. This difference is found to depend on the substance and the form of the sounding bodies, and also upon the various external circumstances in which they are placed. In comparing the properties of these substances, we shall find them distinguished from each other by the de- gree of vibration which they are capable of having ex- cited in them, and by the length of time during which they can preserve a vibratoiy motion ; those substances which are most capable of vibration being most sonorous, and those which can longest maintain a state of vibra- tion also persevering longest in emitting sound. In- stances of this law will readily suggest themselves to the reader. Bodies, though of the same substance, differ in these respects according as their form varies ; those forms which are most favourable to the produc- tion and continuance of a vibratory motion, being also most propitious to the production and permanence of sound. A similar analogy prevails with respect to the exter- nal circumstances which affect sounding bodies ; and gives US sufficient ground to believcj that there is some ACOUSTICS. 107 connexion between the production of sound and the vi- bration of bodies. Accordingly, wlieu a body sounds powerfully, such as a large bell, or the lowest siring of a harpsichord, we can, by the naked eye, perceive that it actually vibrates ; and even in those cases where this is not so perceptible, we may detect it by the microscope, or some other artifice. Thus, if we put some water into'a glass, and make it sound, as in the experiment first mentioned, the water will be agitated. If we hold the open hand over the pipe of an organ, we shall feel a tremulous motion in the air passing throiigh it. Such rxperiments may be extended to all solid bodies, by strewing them with fine sand, or placing upon them small pieces of paper. These observations, showing that the intensity and permanence of the sounds which can be produced from sonorous bodies, are uniformly proportional to the de- gree and permanence of the vibration which can be ex- cited in them, and that the production of sound is al- ways accompanied by such a vibration, prove, that sound and vibration are necessarily connected, either as cause and effect, or as simultaneous effects of the same cause. But as we are already acquainted with the causes on Mhich vibration depends, and which sufficiently account for it, there reinains for us either to consider sound as produced by vibration, or to believe that tliose physical properties by which bodies vibrate, are capable of be- ing at the same time excited to some other mode of ac- tion, by which they produce sound : Thus, when we strike a bell with a hammer, and produce a sound, we may either suppose, that the vibration which is thus excited is the cause of the sound, or we may imagine, that those physical properties which render the bell ca- pable of vibration are excited to some other mode of action which produces sound ; and that the hammer not only acts by its impulse in producing vibration, but also exerts some other influence which excites sound. This latter opinion will appear inadmissible, if we consider, that a tendency to produce inotion in the sounding body is the only thing common to the several modes of excit- ing sound ; and that the physical properties by which bo- dies vibrate are not in all cases the same ; some vibrating in consequence of their cohesion, some by means of a strong repidsion between their particles, which opposes their being compressed, and others from either of these causes separately, or from both of them combined. Though these observations, we conceive, sufiicient- ly establish the opinion, that vibration is the cause of sound, it may be satisfactory to deduce the same doctrine from the two following experiments. Let AFB be a string, stretched between the two pins A and B,one of which, B, is moveable round a hinge at C, and has attached to it an arm CD, from which the weight E is suspended. With the point of a quill in- flect the string into the position AGB, and let the string then slip from the point. It will immediately fly towards AFB, on each side of which it will vibrate, and at the same time send forth sound. Here it is evident, that neither the quill, nor the tension of the string, acts in exciting sound, farther than as they are favourable to the production of motion in the string ; for their action produces no sound till, by the removal of the quill, the tension is enabled actually to produce motion. Instead of forcibly removing the string, a., in the former experi- ment, raise the arm CD, so that the string may hang loose in the form AHB, and then suddenly let go the arm D ; in this case also the strmg will soimd, and give exactly the same tone as in the former experiment. These two modes of exciting sound arc similar in one respect only. In botli the string is at freedom, in a position from which it is moved l)y its tension ; and dur- ing this motion it sounds. We conceive it would be superfluous to adduce more proofs that motion is the cause of sound, and that generally this motion is vibra- tory ; we shall therefore proceed to consider the pro- duction of sounds indued with peculiar qualities. CHAP. 11. Of the Production of Particul.\r Sounds. Sect. I. General Remarkn. The diff"erences in quality by which sounds are dis- tinguished from each other, do not immediately depend on corresponding differences in the nature of the bodies from which the sounds issue ; fur, by various artifices, we can procure, from bodies consisting of the same sub- stance, sounds which shall differ in almost any respect we choose. It is then by examining those artifices, and investigating in what respects their mode of operation can differ, or correspond, that the immediate causes of the different qualities of sound can alone be discovered. The circumstances which affect the sounds of bodies are, their form, their magnitude, their density, the mode by which they are excited, and the comparative force of the power by which they vibrate. As these must evidently affect the vibration of the sonorous bodies, the above-mentioned investigation necessarily supposes, that we trace in what manner the vibration of a body is chang- ed by a variation in these circumstances. This research, however, requiring a considerable ac- quaintance with the higher analysis, we shall at present- take for granted the results to which it leads ; referring those readers who arc versant in mathematical inquiries to the word Vibration, and to the authors quoted at the end of this article. Those philosophers who have investigated the vi- brations of bodies, have arrived at the following con- clusion, that whatever affects the vibration of a body produces a corresponding effect on the qualities of the sounds which it emits ; and, conversely, that those bo- dies whose sounds are similar, have some thing in com- mon in their mode of vibration ; — consequently the dif- ferent qualities of sound are caused by something pe- culiar in the vibration of the bodies by which the sounds are produced. All continued sounds, which remain in any degree uniform throughout their duration, are capable of being compared with each other in their degree of acuteness. When sounds are equally acute, they are said to have the same pitch ; but when they differ in acuteness, that sound which is shriller is said to be acute, or to have a higher pitch ; and that which is less shrill, is said to be graver, and to have a lower pitch, or a deeper tone. A difference in pitch forms the chief character by which musical sounds are distinguished from each other, and is the foundation of their use in music. In unmusical sounds, it generally holds a place subordinate to their other qualities. Musical sounds have occupied the attention of phi- losophers more than any other class of sounds. The superior precision with which the ear can estimate any variation in pitch, renders these sounds more easily com- pared ; and the vibration of the sonorous bodies whieh O 3 108 ACOUSTICS. produce thcni, arc, on iiccouni ol' their superior simplici- ly of form, more easily investigated. We have ah'cady mentioned, that the physical pro- perties by which bodies vibrate are not always the same ; some vibrating in consequence of their cohesion ; others from a strong repidsion, which the particles exert on each other, such as the different kinds of air ; and a third tiass, such as the metals, being capable of vibrating, by either of these forces, separately, or by the combined action of both. It is convenient to arrange the sonorous bodies, which produce musical sounds, rather according to the powers by which they actually vibrate at the time when under our consideration, dividing them into the three following classes, — those which vibrate by cohesion alone, — those which vibrate by repulsion, — and those which vibrate by the combined action of Ijoth. According to this mode of division, the same body may successively appear under each of these different classes. But as its mode of vibra- tion and of sounding follows different laws, according to the division in which for the time it appears, we may consider it in each as a different sounding body. The first class includes all bodies vibrating by tension, such as musical strings, when vibrating laterally ; the second class includes wind instruments, and the longitudinal vibrations of rods, strings. Sec. ; and the third class com- prehends the lateral vibrations of elastic rods, bells, plates, rings, cylinders. Sec. Sect. II. Of l^lunical Stringa. A musical string is of an uniform thickness, and stretched between two points, by a force much greater than its weight. The stretching force which is applied, is generally conceived as measured by the weight, which would occasion an equal tension. In the usual mode of exciting a musical string, it vibrates on each side of its quiescent position, tlie extremities being the only points of the string which remain at rest. The sound which the string gives in this mode of vibration is called its funda- mental sound. The pitch of the fundamental sound of musical strings is found by experience to depend on three circum- stances ; the length of the string, the weight of a given portion of it, and the force of tension to which it is sub- jected. The tone becomes more acute as we increase their tension, or diminish their length, and the weight of a given portion. Thus the dimuuition of the length of strings, and of the weight of equal portions, produce the same effect upon their pitch as if we had increased the force of tension. If strings, therefore, differ from ea^fi other in arty two of these circumstances, we can, by a pro- per adjustment of the tliird, produce from them sounds whose pitch will be the same, or which shall differ in any degree we choose. On this fact depend, for the most part, the various modes of producing the several musical sounds in stringed instruments. — These circumstances also affect the time occupied by the vibration of an uni- form string. Let AFB vibrate between the points G and K, we call its motion in one direction, from G to K, a single vibra- tion ; and its motion in returning from K to G, another single vibration ; and these two motions, which it per- forms between the time when it leaves G and returns to the same point, are, when taken together, called a dou- ble vibration. It has been demonstrated, that the time of a double vibration, expressed \n parts of a second of time, will be found by the following operation : Multiply the number of inches described by a falling bouy in a seco..d ot" time, that is 193 nearly, by the weigiit which is equal to the force of tension ; and, by this product, divide the weight of two inches of the string, extract the square root of the quotient, and multiply the root thus found by the length of the string in inches ; the result will be the time of a double vibration expressed in parts of a second of time. Tiie same thing may be expressed moie conveniently by an algebraic formula. Let L represent the length of the string in inches ; w, the weight of an inch of the string ; ^, a weight ccjuivalent to the force of tension ; g, the number of inches through which a body falls in a second of time, by the action of gravity ; and T, the time of a double vibration expressed in seconds. Then _. or T = L fc/ ^ \9ot T=- >/ g t As the distance of the string from its quiescent posi- tion does not form an element of the algebraic expres- sion, which is thus found for the time of a vibration, it follows, that this time is hidependent of the distance, and that a string performs each of its vibrations in equal times, whether in these vibrations its excursions on each side of the axis be great or small. So long, then, as the string continues vibrating in the manner which pro- duces its fundamental sound, its vibrations will be iso- chronous. Upon this isochronism depends the unifor- mity of its tone ; for, if we employ a string of unequal thickness, and whose vibrations are consequently per- formed in different tunes, the sound which we procure is confused and variable; and any other mode by which we destroy the isochronism produces a similar effect. The same law has been found to extend to the other cases of musical sounds being produced by vibration ; and therefore we may conclude, that isochronism, in the vibrations of sonorous bodies, is essential to their pro- ducing musical sounds. The number of vibrations performed by a string in a second of time, is evidently the reciprocal value which we have found for the time of one vibration ; so that if N represent the number of vibrations, we shall have this formula : v/ T7' v/l93< N =T — —=., or N =T Lv'2' 'Lv/2 w The frequency of vibration which this equation gives, is found to agree very exactly with the result of expe- riments performed with strings, whose vibrations are so slow as to admit of being numbered. The relation between the number of vibrations per- formed by different strings, may be expressed by a more simple foiTnula; for g and the number 2 being both constant quantities, they may in this case be re- jected, and we get the following proportional equa- tion ; n- s/ L^- According, then, as we diminish the length of a string, and the weight of an inch of it, or increase its tension, we increase its frequency of vi- bration ; but equal changes in these circumstances do not produce equal efi'ects. Thus, if in different strings, their tension and the weight of an inch remain the same, their frequency of vibration will be inversely as their •w ACOUSTICS. 109 lengths, or n =- — ; so that if we make the length one- third, we triple the number of vibrations : If the length and tension remain the same, n = , or the ninnbcrof V TO vibrations is inversely proportional to the square roots of the weights of equal lengths of the respective struigs ; and if the length and the weight of equal portions be the same, n -^ y';, or the frequency of vibration is as the square roots of the tension to which tlie respective strings are subjected; the efi'cct which each of these circum- stances has in increasing the frequency of vibi'ation is exactly proportional to its effect upon the pitch of the string; for if we diminish the length of a string to one- third, it would require I'ne weight of equal lengths of tlie chord to be diminished to one-ninth, or the force of tension to be increased nine times, to produce an equivalent effect upon its pitch. As there is no other conceivable mode in which the action of these circum- stances can correspond to the changes they produce in tlie pitch of a sonorous body, it is impossible to doubt that the frequency of vibration is the cause on which the pitch of sonorous bodies depends. If, in the beginning of its vibration, a string has any form ABC, wholly situated in one plane, and on one side of its axis AC, it follows from theory, and accords with observation, that at the end of a single vibiation it will have assumed on the other side of its axis, a form ADC, perfectly similar, but in an inverted position ; so tliat the portion DC shall be equal and similar to BA, and the portion DA to BC. The chord will consequent- ly, at the end of a double or complete vibration, return to its initial form ABC. Every musical string is capable of viljrating laterally, in a mode considerably different from that by which it produces its fundamental sound. Let a string, AE, have an initial form, AwBwCi/DrE, of which equal and similar portions AwB, B/;C, CyD, DrE,are on different sides of its axis, and let these por- tions be arranged in such a manner as that, in any two adjacent portions, their extremities, which meet in the point of division between them, shall be similar to each other: Thus, in the portions A;»B, and B»C, which meet in the point B, let the extremities wB and «B be similar; and in the portions B»C and C(/D, which meet in the point C, let wC be similar to C7, and «B consequently si- milar to cjQ ; and let the same law extend to all other portions. The several points in which the string cuts its axis must remain at rest, and, at the end of a single vibration, the string will have assumed the form A/BoC/iD.vE si- milar to its initial form inverted; and, at the end of a complete or double vibration, it will have returned to its original position. For if we conceive the points, B, C, D, to be fixed in their present position, by means of pins, then it is evident that, as these equal and similar por- tions, A»!B, BnC, C9D, DrE, begin theii- vibration at the same instant of time, and in similar circumstances, the changes which they may have sustained at any mo- ment of time during the vibration will be exactly the same. They will consequently remain similar through- out the vibration, and at each instant of time solicit the points of division between them with forces which are equal, and in contrary direciions; these points of divi- sion therefore will remain at rest, though the pins by which they are fixed should be removed. The sounds which a string gives when vibrating in this manner, arc called its harmonics; the points of the string which re- main at rest are named vibration nodes., ov fiointu oj' divi- sion ; and the vibrating portions intercepted between them are denominated bellies or loo/is. It is hardly necessary to remark, that the whole string performs its vibration in the same time with any of its loops; and that the time occu])ied in performing a com- plete vibration, will be found by considering any of the loops as a separate string fixed at both extremities, and applying to it the formula given above for llie fundamen- tal vibration of strings. This application may be made in the following manner: Let L lie the length of the whole string, b the number of bellies or loops, then L divided by 6, will be the length of each loop, which we may sub- stitute in the formula instead of L ; by this substitution we transform these formulae into the following : '^VlTo 'W'^t ^-y/T" T=- Wis "Lv/2. These equations are very general in their application, and evidently include those given for a string vibrathig in its fundamental mode; for in that case b becomes i, and totally disappears from the expressions. In com- paring the number of vibrations performed in a given time, by a string emitting its difle rent sounds, the quan- tities, L, g, I, and to, becoming constant, may be re- jected, and we get this proportional equation, n~b ; or the number of vibrations performed by a given string in a second of time, is proportional to the number of loops in which the string vibrates : the harmonic sounds of a chord should consequently be more acute than its fundamental sound. The complicated form which a chord assumes when giving its harmonics, would lead us to suppose, that such sounds could hardly ever be excited ; but this is by no means the case, for harmonic sounds may be easily produced by drawing a bow across the string AE, and lightly touching the point of division D. In some mu- sical instruments these are the only sounds employed ; and in all such cases we can, by putting bits of paper on the string, prove that the points of division are at rest while the intervening portions are in motion. A string has, in the foregoing remarks, been consi- dered as producing, at a given time, but one simple sound. This, however, is seldom the case, as sonorous bodies, at the same time that they produce their funda- mental, produce also one or more of its harmonics. For such an accompaniment, it appears at first sight difficult to assign a proper reason, as that vibration, which theory attributes to the chord, seems fitted to produce only one sound. Philosophers have accordingly, in general, been dis- posed to attribute the production of these hai'monics, to something external to the vibrating string; some sup- posing them produced in the transmission of the funda- mental to the ear; some conceiving that they arise from the peculiar structure of that organ ; others, as La Grange, referring them to sympathetic vibrations in the different bodies adjacent to the string. These different opinions, however, are untenable ; for some bodies, such as a drink- ing glass, when excited by rubbing a moistened finger along its edge, or an jEolian lyre, when acted on bv the wind, give exactly the same notes with a vibrating string, but unaccom])anied with harmonics. Dr Tho- mas Young has also found, that even in the same chord it is not universally true, that the fundamental sound 110 ACOUSTICS. must ahvays be accompanied by all llic harmonics of which the chord is susccplil)le ; for thul by inflecting the chord exactly at any (joint in which the chord may be divided into a luimoer ol ctjual parts, and llien suf- ferinir it to vibrate, we lose the uflectoi' tlie correspond- ing harmonic. The just inference Irom this is, that the production ol' the liinuaniciital in conjunction with its harmonics, depends neither upon any ming in the trans- mission of the sound, nor upon the peculiar structure ol the car, nor upon any agitation of the surrounding bo- dies, but rather upon the manner in which the string vi- brates. One of the simplest modes in which we can conceive harmonics, produced by the peculiar manner in which the siring vibrates, is by supposing (agreeably to the theory of Daniel Bernoulli, which \vc have already mentioned) that while the whole of tlie string, ABCDE, vibrates on each side of its axis AE, producing its fun- damental sound, it serves as a moveable axis to partial vibrations of its aliquot parts AB, BC, CD, DE, in the same plane with it, producing the corresponding harmo- nic. That a string can, in some measure, assume such a mode of vibration, is shown by professor Robison ; who, in some experiments with the covered string of a vio- lincello, sounding by the friction of an ivoiy wheel, found, that if he "put somethhig soft, such as a lock of cotton, in the way of the wide vibrations of the chord, at one-third and two-thirds of its length, so as to disturb them when they became very wide, the string instantly put on an appearance something similar to I"ig. 3, per- forming at once the full vibration competent to its whole length, and the three subordinate vibrations, correspond- ing to one -third of its length, and sounding the funda- mental and the 12th with equal strength. In this man- ner all the different accompaniments were produced at pleasure." These experiments show, that harmonics may be pro- duced in the manner supposed by Bernoulli; but to de- termine whether this be the usual mode of their produc- tion, by a string vibrating freely, requires that we trace the actual motion of the string. Dr Thomas Young is, we believe, the only philosopher who has attempted this with any success. He observed, by a microscopic in- spection of any luminous point on the surface of a chord, for instance the reflection of a candle in the coil of a fine wire wound round it, that the vibration of a chord de- viates from the plane of its first direction, and becomes a rotation or revolution, which may be considered as composed of various vibrations in different planes ; and that besides these vibrations of the whole chord, it is also frequently agitated by subordinate vibrations, which constitute harmonic notes of difierent kinds. It is to be much regretted, that the other avocations of that inge- nious gentleman have prevented his prosecuting these observations, so as to refer each separate harmonic to the particular subordinate vibrations on which it de- pends, and trace the peculiar mode of division which the chord sustains, in assuming each particular vibra- tion. Yet we conceive that we do not transgress the due bounds of philosophic caution, in considering these observations, combined with the experiments of profes- sor Robison, as sufficient proolthat the harmonics which accompany the fundamental sound of a string, are occa- sioned by the fundamental vibration of the string being combined with subordinate vibrations of its aliqu'ot parts, either in the same or in different planes. There are several sources from which these partial vibrations may be supposed to originate, such as inequalities in the thickness of the chord, or in the density or flexibility of its difl'erent parts, and also the particular mode of exci- tation which has been employed in producing the fun- damental sound. All tliese causes are pronably com- bined in the production ol theefl'ect; but we know little respecting the particular operation ol each of them, and still less concerning the general result of their combined action. Surfaces in a state of tension, such as the top of a drum, the tambourine, kc. may perhaps be considered as included under this division of the sources of musical sounds. Their mode of vibration, however, is little un- derstood, and, we conceive, not very interesting. Sect. III. Of Musical Bodies vibrating by ReJiuUion. The sonorous bodies which lately passed under our review, produce sound by vibrating laterally on each side of a fixed axis. Those which we are now to con- sider, perform their vibrations longitudinally, or in the direction of their length. Wind instruments constitute one of the genera of this class, and though the air which vibrates in all of them is the same, yet they admit of such a variety in their form, and derive such different characters from this va- riety, that they may be regarded as a genus not less ex- tensive and important than the class of bodies which vibrate by tension. The longitudinal vibration of clastic fluids accordingly soon attracted the attention of philo- sophers, and several interesting facts were discovered ; but it must be owned, that this subject is still imper- fectly uiKlerstood, and that many of the phenomena have not yet received a proper explanation. We are indebted to Mr Chladni of Wirtemberg for the important discovery, that elastic solids, and even strings in a state of tension, arc also capable of vibrat- ing longitudinally ; and in this mode ol vibration obey the same laws with elastic fluids. It is almost certain, though die experiment is encompassed with such diffi- culties as never to have been tried, that those fluids which are usually called non-elastic, admit of similar vibrations. Thus, the class of musical bodies vibrating longitudinally, is not only more diversified in its powers than the other classes into which we have divided sound- ing bodies, but also more extensive in the range of sub- stances which it comprehends. An uniform rod of any solid substance, or a column of air contained in a cylin- drical tube, whose diameter is everywhere equal, may have its vibration limited at both extremities by an im- moveable obstacle ; or both extremities may be at liber- ty ; or one extremity may be confined, and the other disengaged. Though philosophers are by no means unanimous in their opinions with regard to the mode in which the vibration is produced and maintained in each of these cases, they uniformly agree in concluding, that a column of air, or a rod of any substance, if either con- fined, or free at both extremities, performs a double vibration in the same time that a minute impulse would occupy when travelling in a medium of the substance through twice the length of the sonorous body ; and that in a body fixed at one extremity only, it will occu- py double that time. It therefore becomes of importance to consider what are the velocities with which an impulse can be transmitted through different media. Let 1° be the elasticity of the medium measured by a weight, whose pressure on a square inch of the medium would counterbalance the elasticity, /i the weight of a solid inch of \vater,s the specific gravity of the medium, ACOUSTICS. Ill 5- the number ol inches through which a heavy body falls in the first second of eime. Tiien 11, wiien tlie nicdiuni is compressed suddenly uUo less space, its ciasticuy at the moment ot compression uicreases in the same pro- portion with its density, it may be demonstrated liiat v, the number of inches tlirough which a minute impulse will be conveyed in a second of time, is V =:^_£^, and by rejecting the constant quantities 2 ^ and/;, wc get this proportional equation V 4= ^ _L_ This equation, or one equivalent to it, is in general, the only one mat is given on this subject by the ele- mentary writers. But as it is founcied on the hypo- thesis, tliat during the transmission ol an impulse, the momentary elasticity of any medium increases in the same ratio witii the condensation to whicn it is subject- ed, it can be applied to those cases alone in which this hypothesis holds true. Such cases never occur in na- ture ; lor m every hody with whicli wc are actiuainted, condensation produces an elevation ot temperature, and an elevation of temperature always occasions an increase of elasticity ; consequently during the condensation sus- tained in transmitting any minute impulse, the elasticity of the medium increases more rapidly than its density. The simplest and most probable hypothesis which we can form concerning the relation between the density and corresponding elasticity of a given medium, is, that the latter is proportional to some power of the former. Let m be the exponent of that power, and let the density of the medium previous to receiving the impulse, be con- sidered as unity. Then V = . / ~ ' ^' '" . Similar formu- Ise might be given for several other functions, which the elasticity might be supposed to be of the density ; but the number of such hypotheses is unlimited. From this formula we deduce the following V — ■/ '^ '" •. conse- s quently in the same medium, when of the same specific gravity and temperature, every impulse should be trans- mitted with the same uniform velocity during the whole of its progress. If therefore L represent the length of a body vibrating longitudinally, and having its ends in similar circumstances, either both fixed, or both free, the time of a double vibration will be T = — ■p ; v2cgm and consequently the number of such vibrations in a second of time will be N — '^ ^ ^ g ?" . Similar equations may be procured for an uniform elastic rod, or a column of air fixed at one extremity and free at the other, by substituting 4 L instead of 2 L in the foregoing equations. Unfortunately we can- not, by these equations alone, determine the number of vibrations performed in a second by a given body ; for the elasticity of solid bodies is so immense, that we can- not well employ compressing forces sufficiently power- ful to determine its quantity, or the laws which it fol- lows ; and the several kinds of air with whose elasticity we are better acquainted, seem to preserve themselves distinct from the surrounding atmosphere, for some dis- tance beyond the tube though which they pass; so that, with respect to them, we cannot, with sufficient preci- sion, determine the length of the vibrating body. We are not, however, to consider these equations as ol no service ; for by converting them into proportional equations, wc may derive from them very important in- formation. By comparing the ctiuations for a' vibrating body, free at both extremities, and for a vibrating body of half its length, fixed at one extremity and free at the other, we find that each performs an equal number of vibrations. We may therefore only consider the equa- tion for a body having both its extremities in the same circumstances. From this ecjuation, we procure this ge- neral proportional equation N==^_f_!!i.. If wc now suppose e, m, and s, constant, we Iiave ?; = ^ 1 If Z, ?«, and e, be constant If L, m, and s, be constant If L, ,s, and e, be constant V If L and m be constant Prom these equations we may deduce the following general conclusions concerning bodies vibrating longi- tudinally. The number of vibrations performed in a se- cond of time by a given body is the same whether that body be fixed at both extremities, or free at both ; and therelore its sound in these two cases should be the same. But if the body be fixed at one extremity, and free at the other, its length must be reduced to one half, to make it give the same tone as in the two former cases. This is found also agreeable to experience ; for if we blow into a tube closed at one extremity, it will give the same tone which we procure by blowing into an open tube of double the length. The different pitch of bo- dies vibrating longitudinally, and free at both extremities, depends on lour circumstances, viz. their elasticity, the temporary rate at which their elasticity is increased by condensation, their length, and their specific gravity ; the tone of any body being more acute, according as the elasticity, and the rate of its increase by condensation, are greater, or the length and specific gravity less. These circumstances, however, should not affect the sound in the same degree : thus it would require the specific gravity to be reduced to one-fourth, or the elas- ticity, or m, the index of the power of the density to which the temporary elasticity is proportional, to be qua- drupled, in order to have the same effect which a dimi- nution of its length to one-half would produce. The length of the sonorous body is almost exclusively the only one of these circumstances which we have com- pletely in our power. We can vary the others only in- directly, and in a limited degree, by means of pressure, or a change of temperature. If several bodies of the same substance be subjected to the same degree of pressure and temperature, the frequency of their vibrations should be inversely as theii- lengths ; that is, if any of them be only half the length of another, its number of vibrations should be double the number performed in the same time by the longer body. The sounds emitted l)y such bodies are found to be such as exactly correspond to this difference in the number of their vibrations. If therefore we determine this number for any given length of a body, by com.par- ing its sound with that of a string vibrating laterally, 112 ACOUSTICS. MX can ciisily liiul llic miiubei- corrcbponding loany oilier Icnglli of tlic same body, whilst exposed lo the same pressui-e and tmipeiature. Ill solid bodies tuis detcmiination is easy, but in wind iiisliunients it is extremely diflieult ; lor in these, as we lorinerly mentioned, tne column ot air which forms the vibrating body is not linated Ijy the tube through which it passes, but seems to extend to some distance beyond it. Therelore, lo tiiul the real length ot the so- norous body, we must add tnis distance lo che lengtn of the lube ; and likewise make a small addition, on account of the moulh-piecc of the instrument. These correc- tions are probably tne same lor clitterent lengths of the same tube, when blown with the same force ; but must vary as we change the diameter of the tube, or the strength of the blast, &c. The rate of this variation has not bten well asceriained ; but since, by increasing the diameter of a tube, we flatten its tone in a small de- gree, this correction must increase somewhat with the diameter. This result we would naturally expect, from considering that a slender column ol air, moving with a certain velocity, must lose itself in the surrounding at- mosphere sooner than one of a greater diameter. As an increase ol temperature generally uicreases the repulsion between the particles of bodies, it must either increase their elasticity, or diminish their specific gra- vity, and consequently produce corresponding ehects upon their tone. The length of a vibrating column of air is determined by the length of the tube through which the air passes, and its elasticity by the pressure of the atmosphere ; therefore, in estimating the effects of heat upon the vibration of such a column, the length and elasticity may be considered as constant quantities. The change which can be produced in m, by any moderate increase of temperature, is so small, that it may also be viewed in the same light ; consequently the number of the vibrations which the same column of air perfonns at different temperatures, should be inversely proportional to the square roots of the specific gravities of the air at those temperatures ; and thus the frequency of vibra- tion increased about -Jj, by an elevation of 30 degrees of Fahrenheit's thermometer. The effect which this change in the frequency of vi- bration produces on the pitch of wind instruments, is so considerable, that Dr Smith found his organ a full quar- ter of a tone higher in summer than in winter; flutes likewise, and other instruments blown by the mouth, gradually become more acute as the included air is heated by the breath. Mr Dalton, in his experiments upon the different elastic fluids, found, that they all expand in the same degree, with the same increase of temperature. The frequency of vibration therefore should, in all elastic fluids, be increased nearly y'j, by an elevation of 30 de- grees of temperature. From this, and other similari- ties in the nature of these fluids, we may consider them as differing from each other only in their density ; and therefore the number of their viljrations will vary in the inverse subduplicate ratio of these densities. In the experiments performed by Dr Chladni on the tones of an organ-pipe in diflcrent gases, the sound of carbonic acid gas, nitrous gas, and oxygen gas, agrees with this theo- ry ; but azote and hydrogen gas give a note considerably lower than what we should infer from calculation. Hence we must suspend oiw judgment with respect to the vi- bration of these two latter fluids, till future experiments niav enable us to determine whether the results differ from theory in consequence of any inaccuracy in the mode of perlormiiig the experiment, or from some peculiarity in Uie nature ol these fluids. Variations in the barometer can produce very slight efl'ects on the sound of a column of air ; for as we in- crease the pressure on an elastic fluid, its density and elasticity increase at nearly the same rate. Sulzer, and professor Robison, have indeed shown, that in dry air the densities increase a little faster than the elasticities, and in moist air a little slower ; but by an experiment of the academicians del Cimento, the effect which this irregularity has upon the sound of a wind instrument, seems too minute to be appreciated by the ear. They inclosed an organ-pipe in the receiver of an air-pump, and also of a condenser ; and they found that as long as the sound was audible, its pitch remained unchanged. We are unable to say what effect heat or pressure should have upon the sound of solid bodies, but withhi moderate limits it is probably trifling ; and as we have not in general the necessary data for determining the frequency of their vibration, we must in this cast trust chiefly to experiment. Dr Chladni, who first disco- vered the longitudinal vibrations of solids, found, that the tones of these bodies are exceedingly acute. Thus die tone of a rod of tin is about two octaves and a large seventh higher than that of a column of air in an open pipe of the same length ; one of silver, three octaves and a whole lone ; one of copper, nearly three octaves and a fifth ; and iron and glass, about lour octaves. The same philosopher discovered, that a string can vibrate longitudinally, exactly as a rod fastened at both ends ; and that its tones are exceedingly high, in comparison of those which it gives by vibrating laterally. In this mode of vibration, the pitch in no degree depends on the thickness or tension of the string, but rather on the nature of its substance. Bodies vibrating longitudinally, resemble musical strings, in producing beside their fundamental, several successive harmonic sounds. The different modes oi vibration which solid bodies assume in producing these sounds, have been accurately traced by Dr Chladni. When a rod, free at both extremities, and vibrating lon- gitirdinally, produces its fundamental sound, we may, by strewing it with sand, or by laying light bodies upon its surface, perceive, that there is a certain point in the middle which remains at rest, and at which the vibra- tion of each half stops. In its second mode of vibration, it vibrates like two rods free at both extremities, each of half the length of the original rod; so that there ai-c two points at rest, each one-fourth distant from tlie ex- tremities of the rod. In its tliird mode of vibration, it divides itself in a similar manner, so that it has three points at rest. The sounds thus produced, including the fundamental sounds, correspond in the frequency of their vibrations to the natural numbers, 1,2, S, kc. A rod fixed at both ends, or a string stretched be- tween two pins, vibrates along its whole length, when producing its fundamental sound; and in giving its sub- ordinate sounds, divides itself into two or more parts, each of which vibrates in a n:anner similar to the whole. These sounds have to each other the same relation with the harmonics of a rod free at both extremities, or of a stretched string vibrating laterally. A rod fixed at one extremity, and free at the other, may be considered as forming one half of a rod free at both extremities, and vibrating according to those modes in which the middle point of the longer rod is quiescent. Its harmonics are ACOUSTICS. 11^ accoi'dmgly as the series of odd numbers, 3, 5, 7, Sec. These experiments throw considerable light upon the manner in wliich sound is generated in wind instru- ments. We have already mentioned, that the i'unda- mental sounds of a tube, open at both extremities, and of a tube shut at one exremity and open at the other, bear the same relation to each other with the sounds of a rod free at both extremities, and of a rod fixed at one extremity and free at the other. A similar analogy holds in the secondary soimds, which are produced by these bodies. Thus, by blowing across the extremity of an open tube, we can produce, not only its fundamen- tal sound, but also, by varying the force of the blast, we can excite a series of sounds related to each other in the same manner with those produced from a rod free at both extremities; and, from a tube shut at one end and open at the other, we can procure only those sounds which correspond to the series of uneven numbers. From these analogies, we may safely infer, that the vi- brations in a colimui of air, confined in a tube, are con- stituted in a manner exactly similar to those which take place in a rod vibrating longitudinally. In order to confirm this opinion by experiment, we may remark, that any quiescent point of a vibrating body n\tist, at each instant during the vibration, be acted upon by equal and contrary forces, for it could not, on any other supposition, remain at rest ; and that consequently the adjacent vibrating portions, which are on different sides of it, must, at any time, be either both pressing towards it, or both moving from it. The parts imme- diately adjace]it to a quiescent point are therefore at one time highly condensed by the vibrating portions on different sides of it rushing towards each other; and at another time, highly rarefied by these portions moving off from it in contrary directions. We may prove the existence of such rarefactions and condensations in the column of air contained in a tube, by boring small holes in different parts of the tube, and slightly pasting fine membranes over them ; tlie mem- branes which are adjacent to the quiescent points, will be violently agitated, and those, which are more distant, very slightly affected. Sect. IV. Of Sonorous Bodies -vibrating laterally by the combined Jlction of their Cohesion and Elasticity. The vibrations of this class of sonorous bodies have occupied the attention of several eminent mathemati- cians ; but the difficulty of the subject is so great, as to have prevented them from making much progress in their investigations. The sounds produced by rods, vibrating laterally in different circmnstances, seldom admit of being com- pared with each other. But the times occupied by simi- lar vibrations of rods, in similar circumstances, are di- rectly as the squares of their lengths, and inversely as their diameters. The vibrations of plates are still more complicated than those of rods. Dr Chladni has con- trived to trace these vibrations through singular varie- ties, by strewing the plates with sand, which collects it- self into such places as ar*at rest during the vibrations. Some of the fia^ures which the sand thus assumes, are represented in Fig. 5, 6, 7, 8, 9, Plate II. We know very little more concerning the vibration of rings and cylinders, than that they sometimes divide Vol. I. Part I. themselves into four vibrating parts, sometimes into six, and sometimes into eight. CHAP. III. Of the PRorAGATiox f)/' Sound. In an open space, and through a serene atmosphere, sound is generally propagated, in all directions, from the sonorous body. Sounds, even the most powerful, when thus transmitted fi-eely through the air, diminish rapidly in force, as they depart from their sources, and, within moderate distances, wholly die away. What law this diminution follows is not yet ascertained ; and is indeed, in the present state of Acoustics, incapable of determi- nation. We can at present estimate the force of soimds by the ear alone ; an instrument of comparison, whose decisions on this point vary with the bodily state of the observer, and whose scale expresses no definite relation but that of equality. Though sound has in general, at its origin, a tendency to diffuse itself in all directions, it is sometimes propa- gated more forcibly in one direction than in others. A cannon seems inuch louder to those kvho stand imme- diately before it, than to those who are placed behind it. The same fact is illustrated by the speaking-trumpet; the person towards whom the uistrument is directed hears distinctly the words spoken through it, while those who are situated a little to one side hardly per- ceive any sound. Sound is, in a great measure, intercepted by the in- tervention of any solid obstacle between the hearer and the sonorous body. Thus, if, whilst a bell is sounding, houses intervene between us and the bell, we hear it sound but faintly, compared to what we do after having turned the corner of the building. From this fact, sound would seem to be chiefly propagated in straight lines. If, however, we speak through a tube, the voice will be wholly confined by the tube, and follow its windings, however tortuous ; yet we are not from this to infer, that air is the only medium through which sound can be transmitted. Various other bodies, both solid and fluid, are excellent conductors of sound. If a log of wood is scratched at one extremity with a pin, a person who applies his ear to the other end will hear the sound distinctly. The trampling of horses, too, is heard at a much greater distance, by applying the ear to the ground, than by listening to the sound conveyed through the atmosphere. Several other instances of sound being transmitted through solids, will be men- tioned before the conclusion of this article. Liquids are, in like manner, good conductors of sound. Mr W. Arderon caused three persons to dive under water about the depth of two feet; in that situation they heard dis- tinctly what he spoke to them. We are informed by- professor Robison, that, by plunging his head underwa- ter, he heard at the distance of 1200 feet, the sound of a bell which was rung in the same medium. The cause then why sound is interrupted by the interposition of solid bodies, is not that the body so interposed is inca- pable of conducting sound, but that sound does not rea- dily pass from one medium to another. When a piece of ordnance is fired at the distance of some miles, a certain numlier of seconds intervene be- tween seeing the flash and hearing the report ; the sound of the cannon has therefore occupied this iium •• 114 ACOUSTICS. her of seconds in travelling through that distance. Phi- losophers have endeavoured, by an attentive observation of such facts, to deteniiine the rate at which sound tra- vels througii the air. The mean result of these obser- vations gives to all sounds, whether loud or weak, a ve- locity of about 1130 feet in a second of time. This velocity remains unchanged by those variations in the density of the atmosphere wiiich the barometer indi- cates, but is increased by an elevation of temperature. The time which elapses during the transmission of sound to any moderate distance through solid bodies, is so minute as not to have been ascertained by any direct experiments. We are here naturally led to inquire, in what mode sound is propagated through various media, and what takes place in these media during its transmission. Be- fore we enter on this discussion, let us trace the mecha- nical effect which the vibration of sonorous bodies must produce on tlie surrounding atmosphere. Let the string AFB be supposed, as formerly to vibrate from G to K, it is evident that, in this vibration, it must displace all the air between these two points, impelling it towards K, and, by the action of this impulse, condensing it. The air thus displaced must communicate its motion and con- densation to an adjacent portion; and this second por- tion will act in a similar manner upon a third, and the third upon a fourth, and so on gradually, transferring the impulse and condensation from the nearer to the more remote regions of the atmosphere. While this impulse and condensation are propagated in all directions, the string by vibrating back from K to G, produces a rare- faction in the air adjacent to K. This rarefaction is now communicated through the atmosphere in the same di- rection with the condensation: and, in a similar manner, u counter vibration of the chord produces another con- densation, which is again succeeded by a corresponding rarefaction ; so that as long as the string continues to vibrate, there are successive condensations and rarefac- tions propagated from it in the direction KM, and cor- responding ones in the direction GL. The manner in which these undulations take place may be tolerably well conceived, by considering them as having some re- semblance to the elevations and depressions of the con- centric waves, generated by throwing a stone upon a smooth sheet of water. The facts which might be adduced to prove that an impulse is communicated through the air by sounding bodies, are innumerable. The agitation which the ex- plosions of artillery produce in doors and windows is fa- miliar to the most inattentive observer. Any person who has listen.ed to the sound of an organ, must have per- ceived, that when the instrument was giving its deeper tones, the seat on which he was placed vibrated. The same fact is illustrated with respect to weaker sounds, by the discovery of Dr Wallis, that if near a stretched musical string we sound on any instrument a note in ac- cord with that of the string, the string will vibrate and give the same soiuid. There are striking analogies between the transmis- sion of an impulse, and the propagation of sound through various media; those bodies which are best adapted for the transmission of an impulse, being also the best con- ductors of sound. Thus, air, wood, the metals. Sec. con- vey sound powerfully, and to considerable distances ; while it can scarcely be propagated through a few inches "f cork, and various other substances. The jntensitv of the sound transmitted from a sonorous body through the same medium also varies acconling as the lorcc of im- pulse which the sonorous bouy can impress upon it changes : Thus sounds are much louder in valleys, where the air is dense, and can receive a stronger im- pulse than on high mountains, where it is rarer. If an impulse, or undulation, be communicated through E, a less elastic medium, to AB, the surtace ol one which is more elastic, it will be partially transmitted, and partially reflected ; so that there will be two series of undulations proceeding from AB, the anterior surtace of the more elastic medium ; one througn that meamni G, and another through E, the rarer one ; each of which has a weaker impulse than the orighial undulation. If, again, the second medium be terminated by a third medium H, similar to the first, the undulations which have been transmitted through the second medium G will, in the transition from it to the third, be again par- tially reflected, and partially transmitted : so that in this case also there will be two series of undulations pro- ceeding from the posterior surface of thedenser medium, one of them reflected back into G, and one transmitted into PI ; each having a less force of impulsion than the inidulation In the denser medium, by which they were generated. A similar phenomenon takes place with re- spect to sound. Thus a person, speaking in a large room, perceives the sound of his voice reflected by the sides of the room ; while one placed on the other side of the partition also hears the sound, but much weaker, than if the partition did not intervene. When the diflfci - encc between the two media is veiy great, the undula- tion must be almost wholly reflected ; and in such cases the sound is also chiefly reflected. The velocity with which sound is propagated through different media, observes a similar analogy. By employing the formula which is given in Chap. III. Sect. III. and substituting for ?n the value which may be derived from some of Mr Dalton's experiments, the mean velocity with which an impulse can be transmitted through the atmosphere, will be found to differ but little from that with which sound is propagated through the same medium. Observation shows a coincidence be- tween them still more complete. If, when artillery is fired at a distance, the particles of dust which float in a sun-beam are inspected with a microscope, they will be seen agitated at the same instant that we hear the explo- sion ; and we are informed, by a literary gentleman, that he has observed similar agitations in cobwebs. The impulse by which these bodies are thus affected, must therefore be propagated through the air with a velocity exactly equal to that of sound. The same coincidence cannot be exactly traced in solids, as these bodies trans- mit both sound and an impulse with such celerity, that the time which elapses during the transmission of either has not yet been estimated. In order to complete this analogy, it is only required that w^e should be able to prevent the transmission of an impulse without changing the physical properties of the medium. This we can do in one case only : Let a person draw a string tight over his ears, and let another stretch the string, and suspend a watch to the remote end of it, the sound of the watch will be heard by the person over whose ears the string passes ; if now the string be gradually relaxed, the sound becomes by degrees weaker, and ultimately im- perceptible. From these analogies we must conclude, that the pro- ACorsTics. 11 V pagation of sound depends entirely on the transmission of an impulse which sounding bodies communicate to the surrounding medium. Most writers on Acoustics draw the same inference from the weakness of the sound which a bell emits when struck, in an exhausted receiver, and from its strength in condensed air. Such experiments, though generally considered as decisive, appear to us to admit of two ex- planations, and to be far from satisfactory. We have tliereforc had recourse to other means of establishing our conclusion.

As the time occupied by a rod free at both extremi- ties, in performing a double longitudinal vibration, is equal to that which elapses during the transmission of an impulse through twice the length of the rod ; the cele- rity with which sound is transmitted through different substances, may be easily calculated from the number of vibrations which given rods oi tliese substances perform in a second of time. The same calculation may also be founded on experiments respecting the elasticity of any substance ; but this latter mode is more liable to error than the former. It is, however, the only one we can employ to discover the velocity with which sound is pro- jjagated through liquids. From such calculations the numbers in the following Table have been determined.

It has, however, been long known, that we can hear the sound of a tuning-fork, or any other sonorous body, in several other modes, such as by holding it between the teeth. The following extract from Dr Chladni, who has performed the greatest num- ber of experiments relative to this subject, may bo in- teresting to the reader. " Two persons," says the doc- tor, " who had slopped their cars, could converse with each other, when they held along stick, or a series ol sticks, between their teeth, or rested their teeth against them. It is all the same, whether the person who speaks rests the stick against his throat or his breast ; or when one rests the stick which he holds in his teeth against some vessel into which the other speaks. The effect will be the greater the more the vessel is capable of a tremulous motion. It appeared to be strongest with glass and porcelain vessels ; with copper kettles, wooden boxes, and earthen pots, it was weaker. Sticks of glass, and next to these firwood, conducted the sound best. The sound could also be heard when a thread was held between the teeth by both, so as to be somewhat stretch- ed. Through each substance the sound was modified in a manner a little different. By resting a stick, or any other body, against the temples, the forehead, and the external cartilaginous part of the ear, sound is convey- ed to the interior organs of hearing, as will readily ap- pear if you hold your \^ atch to those parts of another person who has stopped up his ears." In reviewing the whole process which takes place in the production of soimd by a sonorous body, till it makes an impression on the organ of hearing, we perceive its several steps depending solely on some motion accom- panying each of them, and essential to it. From all this the inference is irresistible, that sound is merely a mo- tion originating in the sonorous body, and communicated from it through the intervening medium, to the interior parts of the ear ; and that hearing is merely a sensation produced by the consequent affection of this organ. We have thus eudea%'oured, by a regular induction from the phenomena of sound, to discover its nature ; a mode of procedure which is not only the most legitimate, but also the best fitted to give a distinct view of the present state of Acoustics, and of the evidence on which its theory is established. We may now take an opposite course, and consider the general phenomena of sound in their con- nexion with theory. A noise may be regarded as a single impulse, or se- veral impulses, whose aggregate duration is so short as not to be appreciable. A continued sound is a succes- sion of separate impulses communicated to the ear, and producing separate impressions, but in such rapid suc- cession as not to be accurately distinguished from each other; and thus seeming to form one continued sensa- tion. There are many facts in vision which may illustrate the nature of sound. Thus when we move a flaming stick rapidly in a circle, its path seems to be one con- tinued line of light, though our perception of it must be occasioned by the coalescence of several successive im- pressions on the retina. A musical sound consists of a series of undulations which arrive at the ear at equal intervals of time, and the pitch of the sound depends on the length of the interval between each impression. Musical soimds should therefore be produced, not only by the isochronous vibration of sonorous bodies, but also by any other mode in which a rapid succession of equi- distant impidses can be commimicated to the ear, whe- ther those impulses originate from the same or different sources. In this case theoi-v is confirmed by experiment^ P 2 116 ACOUSTICS. for by drawing a quill slowly across Ihe lecih of a comb, a number of distiiicl noises arc perceived ; but by in- creasing the rapidity with which lliese noises succeed each other, they finally coalesce in one unbroken sound of a determinate pitch. In a similar manner the distinct pufl's arising Irom the alternate opening and shutting of a stop-cock, attached to the wind-chest of an organ, form, when lepcated with suflTicient frequency, a very smooth musical note. We may reciprocally, by increasing the capacity of a cavity attached to a pipe, gradually re- duce the frequency of vibration till the sound becomes at last analysed uHo distinct puffs. The numbet of undu- lations which constitute the sound of any sonorous borly, is exactly equal to the number of complete vibrations •which the body performs in the same time ; and may therefore be determined by the methods whicn are men- tioned in Chap. II.* According to the experiments of Sauveur, the lowest sound which tlie ear can appreciate consists of 121 undulations in a second, and the most acute, of sometning more than 6000. Each of the undulations which constitute the funda- mental sound of a sonorous body, may contain within it several minuter rarefactions and condensations, thus producing at the same time the sensations peculiar to the fundamental sound, and to its harmonics. Wiien two bodies, whose sounds are the same, arc adjacent, they reciprocally affect each other's vilirations through the mediiun of the air, m such a manner that these vibrations become synchronous, or performed to- gether ; and thus both bodies conspire in producing each condensation and each rarefaction ; the result of which co-ope ration is a more pleasing and uniform sound than either of them would produce separately : but if the sounds of the two bodies differ a little from each other, the undulations of the one sound will have a ten- dency sometimes to destroy, and sometimes to enforce the undulations of the other. Thus if one sound consist of 90 undulations in a second, and the other of 93, every 30th midulation of the one will coincide with every 31st undulation of the other, and tend to strengthen it, whilst the intermediate undulations will in some measure coun- teract and destroy each other. The coincident pulses therefore of the two sounds must make a more power- ful impression on the ear than the other undulations ; producing what is called a beat in the sounds. By means of these beats, we can frequently determine by the following rule the absolute nutiiber of pulses which constitute any two soinids whose relative frequency of imdulation is known. Express the relation between the sounds in the lowest possible numbers, and these, multi- plied by the beats during a second, will respectively give the number of undvdations in a second, which con- stitute each sound. When the beats of two sounds recur in such rapid succession as not to be separately distinguished by the car, they coalesce into a third sound, which is called a jjrave harmonic. The hardness or softness of a musi- cal sound depends upon the condensation in its undu- lations being abrupt or gradual ; consequently all sounds become softened as they depart farther from their sources. Otner variations between ditVercnt sounds are partly produced by the particular order in which tiic un- dulations succeed each other, and partly by differences in the form of each undulation. As undulations are sent off from sonorous bodies in a form nearly spherical, the force of each nmst dimin- ish as the square of its distance from the sonorous body increases ; and from this several autliors have inferred, that the intensity of sound diminishes at the same rate. If, however, we estimate the intensity ol soimd by the degree ol sensation which it is fitted to produce, it pro- bably dimniishes at a more rapid rate ; for in all our senses the force of sensation does not depend merely on the degree ot excitement, but also on the suddenness of the excitation ; consequently if two undulations have each an equal impetus, the one in which the condensation is most abrupt and contined within the narrowest limits, should produce the most vivid sensation. The crossing of sounds in the air, without being mutually destroyed, must arise from the air in the point of their intersection partaking of both motions. CHAP. IV. Of the Reflectiok of Sound. A sound, whose progress is interrupted by any solid obstacle, must be partly transmitted, and partly reflec- ted, with a velocity equal to that which it had before impinging against the obstacle. The reflection of sound differs from that of light m tlic degree of smoothness required in the reflecting surface ; thus walls, rocks, and many other bodies whose surfaces have considerable ir- regularities, reflect sound very perfectly. La Grange has, however, demonstrated, that, in sound, as well as light, tlie angle of reflection is equal to the angle of in- cidence ; and therefore, by employing the laws of ca- toptrics, and keeping in view, that sound has generally a tendency to be a little scattered by reflection, we may obtain an explanation of several interesting pheno- mena. When a sound, issuing from a distant point, impinges on a concave surface, it converges to a certain point after reflection ; and a person, situated near that point, will hear the reflected sound more distinctly than the direct sound. A similar effect will be produced by reflection from several plain surfaces properly situated. If the reflecting surface be of an elliptical form, all the sound which proceeds from one of its foci is reflected to the other. To such a reflection, the phenomena w hich take place in the whispering gallery at St Paul's and several other buildings, is frequently ascribed. A person stand- ing near the wall with his face turned to it, whispers a few words, which are heard by another, who applies his • Professor Robison, in the article Trumpet, vol. ii. p. 720 of the Supplement to the Encyclopedia Britamncn, gives a rule for deter- mining tlie number of aerial pulses made by an open pipe of any given lengtli, wliich will be very apt to mislead tlie incautious reader. The learned professor, in that rule, consider.'! the number of pulses as equal to the number of vibrations performed by the air in the pipe, and determines the number of vibrations, by extending to an open pipe the formula which he had previously found for the vibra- tions of a string. Xow, as that formula expresses the single vibrations of a string, the extension of it must express the ntimber of single vibrations of the air in a pipe, and consequently give double the number of pulses. If tliis rule be applied to the e.xample given in the second next paragraph, it will be found to give double tlie number of pulses mendoned there by that philosopher. We have been induced to mention these circumstances, lest those readers, who might not choose to investigate the principles on which the rule :s founded, should, upon comparing it with our forraida, and findiiig the results different, call in question the accuracy of the latter. ACOUSTICS. U7 ear to the wall at nearly the opposite side of the building ; though the sound is not perceptible to tliosc who are situated nearer to the speaker. The position of the speaker is in this case such, that the sound must, after reflection, diverge, instead of convergins^, to tiie oppo- site point ot the building; consequently the effect must arise eitlier from two or more successive reflections along the sides of a polygon, or from a continued deflec- tion ot the sound along the wall. To determine which of these is the cause of the phenomena, would require several experiments. The Hall uf Secrets, as it is called, in the observatory at Pans, produces a similar effect, but in a rrjore pertect manner. This hall is of an octagonal form, with cloister arches, or arched by por- tions of a cylinder, which meet at angles, corresponding to those formed by the sides of the b\iikUng. The speaker applies his mouth very near the wall to one of the angles, and the person situated at the opposite angle hears his voice distinctly. Montucla thinks, that, in this case, " there can be no reflection of the voice, according to the laws of catoptrics ; but that the re-entering angle, continued along the arch from one side of the hall to the other, forms a sort of canal, which contains the voice, and transmits it to the other side." We conceive, however, that the effect may also be accounted for by successive reflections along the arch, as completely as by a continued deflection ; but we shall not presume to affirm on which of these it depends. The most frequent instances of the reflection of sound are from surfaces, which may be considered as plane. In these, the sound issuing from any point seems, alter reflection to proceed from a point equally distant and similarly situated on the other side of the reflecting surface; the phenomena differing a little according, to the position of the speaker, with res'pect to the body which occasions the reflection. If a person's voice strike any surface perpendicularly, it will be reflected back in the same line ; and the time occupied between the utterance of the sound and its arrival again at the speaker, will be equal to the time in which sound travels through twice the distance between the speaker and the reflecting surface. This time may therefore be expressed in seconds, by a fraction whose numerator is twice the distance, anil whose denominator is 11 30 feet. If the distance of the reflecting object is less than 47 feet, then the interval between tjie impression pioduced on the ear by the direct sound, and that produced by the reflected sound, will be less than -^-^ of a second, and the two sounds Will consequently seem to constitute a single sound ; but when the distance is greater than 47 feet, the interval of time between the speaker's hearing the direct and the reflected sounds exceeds ^j of a second ; and as this interval can be discerned by the ear, the two sounds will be separate, and therefore form an echo. A reflecting surface will return the echo of one or more syllables in proportion to its distance from the speaker ; for the last of the syllables must be uttered before the echo of the first arrives at the ear. It is computed, that, in the usual way of speaking, each syl- lable is pronounced in about y of a second^; the distance therefore of a reflecting object must be as many times 161i feet as the echo returns syllables. A compound echo, or one which repeats the same sound several times, is occasioned by several reflecting surfaces, sit- uated at different distances from the speaker. But for the more particular consideration of this subject, we must refer to the article Echo, PART. II. PRACTICE OF xlCOUSTICS. The practice of Acoustics is confined to instruments for the production of sounds ; — for the transmission of sound to greater distances ; — for concentrating sound after its transmission ; — and for measuring the relations of sounds. Sect I. On Xratzenstein's Vowel Fi/ies. The sounds produced by instruments are chiefly musical. Kratzenstein and Kempelen have, however, by making experiments on the effects of pipes of dif- ferent forms, succeeded in constructing such as shall imitate very accurately the different vowel sounds pro- duced by the human voice. The theory of the vibration, which takes place in these pipes, is very imperfectly inulerstood, and therefore we must rest satisfied merely with giving sections of them. The sound in the pipe, which gives the vowel /, is produced by blowing through the tube attached to the pipe /; but in the case of the other vowels, J, E, O, and U, by blowing into the pipes with a reed mouth-piece, resembling that of a vox-humana organ-pipe. This mouth-piece is repre- sented in Plate II. Fig. 15, where AB is a semi-cylin- drical mouth-piece with a metallic tongue, or plate, between A and B, by whose vibrations the current of air is alternately admitted and excluded. Sect. II. On the Speaking Trumpet. The speaking trumpet is an instrument intended for transmitting sound to considerable distances in a particu- lar direction. The form which is given to this trumpet is different according to the various theories which have been formed concerning its action, being some- times a parabolic, sometimes an hyperbolic conoid. The form of a simple cone is found to answer fully better in practice than any other. This construction of the in- strument is represented in Plate II. Fig. 11, where A is a mouth-piece, adapted to surround the lips of the speaker, and confine the voice. AB is the body of the instrument, being a cone, truncated at A, and gradually- enlarging towards B. Sometimes the instrument is terminated at B, by a sudden enlargement of its aper- ture. The theory of the action of this trumpet has been, in general, very ill understood. The augmentation in the intensity of the sound has been supposed to arise partly from the vibration of the substance of the trumpet, and partly from a reflection of the sonorous rays from, its sides, The former of these circumstances, however, has long ceased to be adduced as a cause of the augmen- tation of sound ; for its effect must be to render the voice indistinct, and nearly unintelligible ; but the latter still continues to be the theory of the action of this in^ 118 ACOUSTICS. btrument, which is usually given by writers on Acous- tics. According to these authors, the sonorous rays A 6, A c, A/, and A g, which diverge from the point A, and which would, if the instrument were not em- ployed, continue to proceed through the atmosphere in their diverging lines, are, by impinging against the points 6, c,f, and g, in the side of the instrument, re- ilected into the parallel lines b e, cd, f/i, and g /c, and thus transmitted to the hearer. This will appear a very defective theory, if we consider, that it extends the analogy between sound and light much farther than we are warranted to do by the phenomena of nature ; for, if we consider sound, at such minute distances, as con- sisting, like light, of distinct and independent rays, the surfaces reflecting sound must require a higher degree of polish than we generally find them to have ; and a wall, or a rock, which at present reflect sound very per- fectly, should rather disperse it in all directions. In a similar manner, the sound of a flute, when all its finger holes are shut, should proceed, without any divergence, through the air in rays perfectly parallel. The same thing should also take place with the sound of a tuning fork, and many other sonorous bodies ; but this is con- trary to daily experience. Indeed, the phenomena of sound at minute distances cannot be explained on any other supposition, than by supposing its undulations to correspond with any compressed fluid, in having a ten- dency to escape in that direction where it is least re- sisted. According to this view of the subject, any un- dulation should enter the trumpet at the point A, in a condensed state, and press against the sides of the in- strument during its whole progress through it, thus uniformly occupying the whole breadth of the trumpet, and becoming more rare as it approaches the extremity B. We may observe, however, that the diminution in its density should be probably greater in the parts adja- cent to the sides of the instrument, than in those nearer the axis. The action of the instrument must therefore chiefly depend either on the confinement of the undula- tion by the tube, or by its gradual diffusion across the whole diameter of the tube. The confinement of the air in the tube must chiefly operate by rendering it less fugacious, and capable of receiving a stronger impulse from the organs of speech, and thus increasing the in- tensity of the sound in the same manner that the sound of a sonorous body is louder in a dense than in a rare atmosphere. A similar explanation is also suggested by Professor Leslie in his ingenious Essay on Heat. On this action of the instrument, the increase of sound, at least at moderate distances, seems chiefly to depend ; for Hassenfralz found, that the beat of a watch, placed in the mouth of a cylindrical trumpet, was audible at nearly double the distance which it could be heard without employing the instrument ; an effect which could not take place according to the usual principles which are employed to explain the action of the speak- ing trumpet. The same gentleman found, in other experiments, that a cylindrical speaking trumpet trans- mitted the sound of his watch to as great a distance as a conical trumpet. From which experiments, and from the preceding remarks, it is evident, that the immediate effect of the speaking trumpet ui increasing the inten- sity of sound, depends in no degree on reflection, but rather on the air being rendered less fugacious, and more capable of receiving a strong impulse. We con- ceive, however, that the gradual enlargement of the in- stmuieut, by rendering the undulation less dense and spread over a greater surface, makes it less apt to dif- fuse itself in a spherical foi-m, and consequently Its': exhausted by being transmitted to considerable distaji- ces. Such an effect actually takes place in the conical trumpet, for it transmits sound chiefly in the direction to which it is pointed. Sect. III. On the Hearing Trumfiet. The form which is usually given to the hearing trum- pet, corresponds to that of the speaking trumpet, in be- ing a cone truncated near its summit, but differs from it in being sometimes of a curved form. The summit of the cone is placed in the ear, and the w-ide extremity turned towards the point from which the sound comes. The effect of this instrument is found to be a very consi- derable augmentation in the intensity of the sound, and it is accordmgly employed by those whose sense of hear- ing is impaired. The common theory of the hearing: trumpet, founded on the hypothesis of reflection, may be easily conceived, by supposing the section of the speak- ing trumpet, Plate II. Fig. 12, to represent a hearing trumpet, of which the summit A is placed in the ear, and d c, e b, h f, k g, to be parallel rays, which impinge against the sides of the instrument, and are converged by reflection to the point A. The theory of reflection is less applicable to the hearing than to the speaking- trumpet ; for when the instrument is of considerable length, or the source from which the sound issues is very near, each ray will sustain several reflections be- tween the opposite sides of the tube, and at each re- flection the angle of incidence will be increased in such a manner, that, after a few reflections, the ray will again issue out at the mouth of the instrument. We must therefore conceive a process the reverse of what takes place in the speaking trumpet ; and that the action of the sides of the instrimient is not limited to the parts immediately adjacent ; but extends to the axis of the tube, gradually transferring the whole impetus, which was impressed on the air at the aperture of the instru- ment to the narrow portion of air at its vertex ; and thus enabling it to act with more energy upon the organ of hearing. Sect. IV. Oji Acoustic Tubes. Sound may be conveyed to much greater distances by being confined, during its whole transmission, within a pipe. Such pipes are frequently used in coffee-rooms and taverns, for conveying orders to the attendants. Dr Herschel employs a similar tube attached to his forty feet telescopes, for communicating his observations to an assistant, who sits in a small house near the instru- ment ; and thus, under cover, notes them down, and the particular time in which they were made. Acoustic tubes are generally of a cylindrical foiTii, and have at each extremity a mouth-piece, like that of a speaking- trumpet, to which either the mouth or ear is applied, according as the person is speaking, or listening to ano- ther. The phenomena of sound when confined in acoustic pipes, demonstrate more completely than even the phe- nomena of speaking and hearing trumpets, that we iTiust be led to erroneous conclusions, by applying to minute portions of sound the laws of catoptrics. According to these laws, when an acoustic pipe is bent at a right an- gle, the whole sound should at that angle be reflected ACOUSTICS. no back in the same paili by which it arrived at it ; and no sound should be transmitted to the other extremity of the lube. This, however, is contrary to fact; for wiien we speak into an acoustic pipe, tlie voice follows its ■windings, however tortuous. The condensations and rarelactions which constitute the sound, must therefore have communicated themselves laterally from the one part of the tube into tlic other, contrary to the laws of catoptrics. The sound thus transmitted must be indeed weakened by a partial reflection, and also by a partial transmission through the substance of the tube ; and the relation between the force of the sound transmitted along the tube to that which is reflected back, must de- pend on the relation which the diameters of the different parts of the tube on each side of the right angle bear to each other, and to the depth of the undufations which constitute the sound. The further consideration of this interesting subject, of which we believe no author has yet treated, we must defer to the article Vibration. Sect. V. Explanation of the Deception called the Invi- sible Girl. Mr. Charles's deception of the invisible girl, is chiefly produced by means of acoustic tubes. In this exhibition a square railing of wood is fixed in the middle of the room, and within this railing a globe is firmly fixed with ribbons, liaving four trumpets inserted into it, one op- posite to each side of the railing. The spectators, by first speaking into any of the trumpets, and then applying their ear to it, hear, in a feeble voice, an answer to their cjuestions apparently issuing from the trumpets. This deception is performed by conveying the sound through pipes, which are conducted from another room under the flooring, and, along a bar of the railing, to a small aperture opposite to the mouth of the trumpet, from which the sound after reflection seems to proceed. The trumpets reflect the spectator's question to the pipe, which conveys it to a person placed in the next room, and also conducts back that person's answer. Sect. VI. On VentriloQuism. Ventriloquism does not, as is frequently supposed, de- pend on the reflection of sound, but wholly on the inac- curacy with which the car judges of the direction from which sounds proceed ; enabling the performer, by a variation of his tone of voice, and by seeming not to move his lips, to persuade the spectators that the sound proceeds from some object to which he has diverted their attention. The deception, therefore, with respect to the direction of the sound, depends wholly on the power which the finesse of the performer gives him over the imaginations of his audience. Sect. VII. On Sounding Boards. Sounding boards are employed in all stringed instru- ments for increasing the force of their sound. A similar contrivance is often employed to assist the voice of pub- lic speakers; but the principles of these two kinds of sounding boards are perfectly distinct from each other. The sounding board employed to assist the voice of pub- lic speakers, depends for its effect chiefly, if not wholly, upon reflection. In stringed instruments, the sounding board receives a vibratory motion from the string, and by thus impelling the air w ith a greater surface, produces a more powerful sound than tlie string alone. That this is its mode of operation, may be easily seen by stretch- ing a musical string over aboard, and pressing the edge of a thin ivory scale, or any other hard body, against the middle point of the string. The sound of the string is feeble, when the scale is merely held in the hand without touching the board, but becomes powerhd when we rest the scale against the board. The same fact may be also proved by stretching the string on some solid body, ia which it cannot readily produce vibration. In this case, the vicinity of that body will be found to have little effect in increasing the sound. The effect of a mute upon a violin seems to arise from its preventing the vibrations of the string from being commiuiicated along the bridge of the violui to the body of the instrument. Sect. VIII. On Sonometers. Sonometers are instruments intended for determining the relation between the number of undulations which constitute the several notes of music. This instrument is usually in the form of an oblong box, upon which two metallic wires are stretched by weights, and which, by varying either their length or tension, may be tuned, so as that their soimds shall have to each other the rela- tion of any two notes of the musical scale. Wc can, then, by comparing the relative lengths, or tension, of the strmgs, easily determine their relative frequency of vibration. The monochord is a similar instrument, having one string only, and generally constructed so as to vary the effective length of the string, by a moveable bridge. For the relations which are thus discovered be- tween the notes of the gamut, we must refer to the arti- cle Music. Sect. IX. Method of measuring Distances by means of Sound. A knowledge of the velocity of sound enables us to measure distances which we can by no other mode as- certain. It has been already mentioned, that sound tra- vels through 1130 feet in a second of time ; and there- fore it must occupy a little more than 4i seconds, or 5 beats of a healthy pulse, in passing through the distance of a mile. Consequently if we divide by 4 1, the num- ber of seconds which elapse between the time of seeing the flash of a cannon, or of lightning, and the time of hearing the report, the quotient will express in miles the distance of the cannon or the thunder.

Chladni Knldec- kungen, so?;a«?, all others corisonant echoes. If it then be assumed as a fact, that in all rooms in which the speaker cannot be placed at a greater distance than forty-seven feet from any wall or ceiling, the pri- maiy echo will so nearly comcide with the voice as to be consonant, then such a room, in wJiatevcr form it may be built, would multiply the effect of the voice by the number of echoes which would be returned to the ear. But as it is necessary to distinctness that each sylla- ble or note of sound, which is uttered, should be heard during the time of its utterance only, the secondary and subsequent echoes, travelling much further than the primary echo, would be still a great cause of confusion. And the fact confirms this reasoning. For in a room about forty feet square and less than forty feel high, if the walls and ceiling be well plastered, and noobstixic- tion given to echo by furniture or numerous persons, in which including that from the floor there cannot be pos- sibly more than six primary echoes, and six in each set of subsequent echoes, it is impossible to speak loud and rapidly so as to be distinctly heard. In rooms, any part of tlic walls or ceiling of which is cylindrical or spherical, and in which of course the echoes are infinitely more numerous, the effect of con- fusion by the interference o£ subsequent echoes is still more considerable. On the plain fact however, that, consonant echoes do support tlie voice and increase its effect, there cannot be any dispute. Theory and experience both confirm it. No echo however can be mathematically consonant; for no case can occur in which the distance of the voice from the ear would be exactly equal to die legs of the angles of incidence and reflection of an echo, the dis- tance between the voice and the ear being a straight line or the shortest distance: still less then can subsequent echoes be consonant. These considerations throw a strong light upon the question of the construction of the rooms enumerated in the first part of the essay, into which I will now enter. If the separate tones or articulations of a voice were made to succeed each other at such intervals, as to leave time between them for the primary and subsequent echoes to arrive at the ear, let their number dependent upon the fomi of the room, be what it may, then no in- distinctness could be produced by them. But if upon the image (if I may be allowed the term^ of one sound, the impression of a different sound be stamped, indis- tinctness of both is the consequence. There are therefore two principal means of avoiding this confusion : — the first depends on the speaker or musician : it is an articulation adapted in its pace to the echoing quality of the roona; — the other is in the pro- vince of the architect, so to construct the room as to regulate its echoing qualities according to its use. The first of these principles has been long understood in practice by professors of oratory and declamation; and it has become a kind of habit among public speak- ers to articulate slowly in proportion to the size of the room in which they speak. The evil although thus re- medied by men who speak according to a regular sys- tem, being inherent in an ill constructed room, will be felt, the moment the warmth of feeling or the ignorance of the speaker causes a more rapid delivery, than is adapted to that degree of echo which is unavoidable. It is then the duty of the architect to suppress or exclude the echoes that would confuse the distinctness of the species of sound which it is the object of the edifice to exhibit. The mode of effecting this object will be dif- ferent according to the different use to which the room is put: ACOUSTICS. 123 I. la churches ajid lecture-rooms in which there is only one speaker, reniaininjj in one place, in wliich the object of instruction, as well as the laws of declamation, require a slow and measured articulation, primary echoes cannot be considered as injurious. They are, on the contrary, beneficial. If the room be a parallelopipedon, Vliere will be five such echoes ; and, presuming the rule (Chap IV.) to be correct, if the mean distance of the voice and echoing surface do not exceed forty-seven feet, the voice will be well heard and supported ; unless the walls be so smooth and hard, and tlie height so pro- portioned to the width and lengtli, as to reverberate audibly, the echo a second time or oftener. The object then would be attained, were the room so constructed that no secondary and subsequent echoes could reach the audience, or that they should be so weak as not to have any perceptible effect. The most effectual means, which could be adopted, would probably be, to prevent all echo excepting from the ceiling, by hanging the walls with drapery, or other- wise covering them so that they should not reverberate sound. Rooms, the walls of which are broken into sunk pannels enriched by relievos, or which are decorated with fluted pilasters, or otherwise so varied in their sur- face as to ofler to the rays of sound, which in this re- spect resemble those of light, no regular mirror from which they can be uniformly reflected, are better calcu- lated to render the voice distinctly audible, than those, the walls of which are unvaried in their surface. As our churches are usually constructed, the galle- ries, the pews, the cornices, the windows and their cur- tains, but especially a crowded congregation, answer the purpose to a considerable extent. If the ceiling be arched and not so high as to produce a perceptible sepa- ration of the voice and its echo, it will be a better room than if the ceiling be flat. If the ceiling be spherical, the effect will be still greater ; but it will be unequal, because the primai-y echoes will be limited to the planes of certain great circles ; as may be easily understood on referring to the observations I have made on the suppo- sition of a spherical room. If the ceiling were parabolic and the speaker placed in the focus, the room would I believe be as perfectly adapted to its purpose as possible. On this one point however I have no experience ; but all my observations on churches and lecture-rooms, actually in existence, confirm the theory I have advanced. The place of the orator is next to be considered.— He ought to be so situated that his hearers shall not be behind him, and also, that he shall be at the shortest mean distance from them. Both these rules, which are all that govern the case, suggest at once the ancient semicircular theatre as the most perfect form of a church or lecture-room, tlie orator or exhibiter being placed in the centre, or moving along the diameter. It has now become a pretty general practice to con- struct lecture-rooms in this form, especially when the nature of the subject explained in them requires room, and the objects exhibited are numerous. In the chemi- cal lecture-room of the University of Pennsylvania, though on a very limited scale, I have endeavoured to adapt the form and arrangement to the principles which I have laid down; and the object in view has been perfectly at- tained. The anatomical theatre in the same building is a cir- cular room covered with a dome. In an anatomical theatre the perfect view of the subject is of as much importance as the perfect hearing of the lecture. The circular form of such a room brings tlic subject, placed in the centre, as near as possible to the eyes of the great- est number of students ; and it is therefore preferable to the semicircular plan. Each of these rooms is 45 feci in diameter. But in churches, habit, and certain rules of form., which have an emblematical origin, forbid the theatrical plan ; and although circular churches have been built by those Christians who have deviated most from the strict system of the catholic church, the expense attending their construction, as well as other considerations, have prescribed to churches an oblong, or cruciform, and rectangular plan. The extent of many churches, and the consequent difficulty of supportmg the roof, have introduced columns or pillars, and aisles into the interior. These, as far as they break the regularity of the enclosing planes, destroy interfering echoes. But they also intercept the view as well as the voice of the speaker. In the plain rectangular churches, most generally required by the congregations of our country, the principal considera- tions would be the place of the speaker and the form of the ceiling. The centre of one of the longest sides, brings the voice to the shortest possible distance from the majority of the hearers ; and if the ceiling be flat it is the most advantageous position. But if the ceiling- be arched, it is better that he should be placed in the longitudinal line, bisecting the area of the church, for the reasons stated above. See Cylindrical Ceilings. I cannot help regretting that the abuse, attributed to the use of pictures and statuary in churches, has expel- led them from most of the religious edifices of our coun- try. Independently of the operation of sensible repre- sentations, of the objects of our veneration or faith, on our minds, pictures and statuary have a great effect in suppressing interfering echoes in churches. The sound- board of the preacher is intended to have this effect, by intercepting the voice before it can reach any echoing- surface ; and it answers the purpose well, especially if lined with velvet, or made of any soft or vibrating sub- stance, which receiving, and as it were absorbing the vibrations of the voice, does not reflect them. 2. T/ieatresand nntsic-rooms. The object of a theatre is to exhibit an extent of scenery to the view, as well as to convey a variety of sounds to the ear. One side or half of the room is therefore necessarily devoted to the voice, the place of which is not fixed, but only limited, to any point within that side ; the hearci-s being confined to the other. All the general principles, which apply to lecture- rooms apply to theatres. The best fonn is the semi- circle, and the best ceiling, the semi-spherical. The extent which this article already occupies forbids my entering into the very useful disquisition of that proportion of the height of the ceiling to that of the walls occupied by boxes and galleries, and to the diameter of the house, which affords the greatest advantage of hearing dis- tinctly what is uttered on any part of the stage. And this disquisition is the less necessary, because the econo- my of space, and the technical arrangements of a theatre, and of the space under the roof, render the rules of construction which the principles of acoustics prescribe, practicable only in small theatres. The sacrifice which in large houses of tliis kind would be made of the room within the roof would be too considerable. On this subject, see the article Civil Architecture and Theatre. Music-rooms require a separate consideration. The Q 2 124. VCR ACR declamation of the stage ought to be adapted in its de- gree of rapidity to the size of the house : and a good actor knows how to measure the pace of his recitation to the greatest advantage, on each stage which he treads. Primary echo therefore may in a theatre be advantage- ously allowed. But in a music-room, echo is the de- struction of the clear articulation so necessary to give cflcct to melody, and to the distinct succession and mo- dulation of chords, without which harmony cannot be understood, or produce its effect. Whoever has been accustomed to attend the European cathedral service, and has been placed in situations in which the echo equalled the original sound in intenseness, must have observed its injurious effect, excepting in very slow successions of chords. In concert -halls, in which very rapid music is to be occasionally performed, there should be no per- ceptible echo. The audience, if numerous, is security against echo from the floor and from a part of the walls ; ■.aid the decorations of the walls themselves, and the draperies destroy the remainder. But experience proves that the destruction of echo may be carried too far even in concert-rooms ; and singers, who are not encouraged by the echo of their own voice, complain exceedingly of the distress they suffer. That part therefore of a concert-room, in which the musicians and singers are placed, should be free from the kind of furniture and decoration which destroys echo ; and although I have no experience to warrant the assertion, I am oi opinion that a cylindrical wall behind them at no great distance would advantageously increase, without confusing, the effects of the music. 3. I^igislative Halls, HalLi of Debate., Courts of Ju»- tice. — The construction of legislative halls to the best advantage of hearing and speaking, is attended with many difficulties wliich are not to be encountered in any room, in which the place of the voice is fixed, or Imiited to a small compass. If perfect silence could be preserved in these rooms, there would be no difficulty which could not be over- come, by adhering to those general principles of construc- tion, which apply to the other classes, excepting one : — the back of the speaker must necessarily be often placed towards the hearer; and on the other hand the back of the hearers must often be turned to the speaker. With- out entering at present more particularly ijito this pait of the subject, the reader is referred to the article Civil Architecture, for the construction which in most respects is found to be the best adapted to its pur- pose.

Each fort has its se- parate village, which are all included under the name of Acra. At Acra alone there is found more gold tlian on the whole coast; and its commerce, already extensive, would be still farther increased, were it not perpetually interrupted by continual quarrels between the natives of Aquamboe and Akcm. The country is fertile, and abovmds in game. This province contains three villages upon the coast, viz. Soco, Orsaca, and the Lesser Acra. The village of Great Acra is six leagues from the sea. The village of Lesser Acra furnishes one third of the gold found on the whole coast. It is brought from the country of Abonoe and the province of Acania. See Dapper's Dcscri/Uion de VAJriquc, p. 287.

Its Arabian name is Akka, which greatly resembles its ancient Hebrew ap- pellation Acco or Accho. Acre is surrounded by an ex- tensive and fertile plain on the north and east : On the west it is washed by the Mediterranean; and on the south there is a semicircular bay nine miles long, which extends from the city to Mount Carmel. TJiis town has been celebrated in history, as the thea- tre of several important transactions. During the holy war, it was the principal scene of contention between the Christians and Infidels. Saladin, king of Egypt, ob- tained possession of it in 1187; and, soon after, it was invested by the combined forces of all the Christians in Palestine. For two years, it was defended with the most obstinate bravery ; an incredible number ol troops, both European and Asiatic, were destroyed; nor did it sur- render till the assailants were reinforced by the armies of Philip Augustus of France, and Richard I. of Eng- land, two monarchs, whose ardour in the sacred cause, and whose emulation of each other's fame, incited them to extraordinary efforts of valour. The Saracens, re- duced to the last extremity, could not long hold out against such formidable enemies, and, on the 12th of July, 1191, they surrendered themselves prisoners of war. Thus, after losing more than 100,000 men, the Christians became masters of Acre, a strong position, and commodious harbour; they procured the restoration of their fellow Christians, who had been taken by the Infidels; and once more obtained possession of the wood of the true cross. Saladin, however, having refiised to ratify the capitulation, Richard I. ordered 5000 of the Saracen captives to be butchered ; and this act of wan- ton cruelty compelled Saladin to retaliate upon the Christians. Almost a century posterior to this event, when, after many unsuccessful attempts to recover the Holy Land, Jerusalem was wrested from the Christians, Acre became their metropolis in Syria, and was adorned with many useful and elegant works; pilgrims and fu- gitives augmented its population ; and the advantages of its situation attracted the trade both of the East and West. At this time, extreme licentiousness prevailed in the city, which the feeble efforts of government were insufficient to restrain. The adjacent Mahometan vil- lages were plundered by gangs of banditti, who sallied ACR ACJ{ 125 forth under the banners of the cross. Nineteen Syrian merchants were robbeil and ignominiously murdered, yet satisfaction was demanded in vain. Incensed by these enormities, the suhan Khalil advanced agauist Acre with a powerful army, provided with a formidable train of artillery. The Moslems, after a siege of thirty- three days, succeeded in storming the town, and 60,000 Christians were either butchered or made slaves. The fortress of tlie Templars was demolished ; their grand- master was slain ; and of 500 knights, only ten survived. Of the fugitives, a very few arrived in safety in the island of Cyprus. This siege was distinguished by an act of female resolution, scarcely paralleled in history. A number of beautiful young nuns, dreading the viola- tion of their chastity by the brutal Saracens, determined to render themselves objects of aversion, by mangling their faces in the most shocking manner ; and when the conquerors eritered the city, they were so disappointed at the disgusting appearance of these virgins, that they put them all to the sword. Acre, after being thus desolated, remained almost wholly deserted, till the year 1750, when it was fortified by Daher, an Arabian scheik, who maintained his inde- pendence for many years against the Ottoman power, and was at length basely assassinated, at the advanced age of 86, by the emissaries of the pacha, against whose tyranny he had, through life, defended his people. Acre has since been rendered, by the works of Djezzar, one of the principal towns upon the Syrian coast. His mosque is admired as one of the finest specimens of Eastern architecture. The bazar, or covered market, vies with those of Aleppo; and the public fountain, though the water is of indifferent quality, exceeds even those of Damascus in elegance. Of these works the pacha has the sole merit, as he both planned them, and superintended the execution; yet, amidst all these im- provements, the fortifications of Acre, though they had been frequently repaired, continued so insignificant, that they were incapable of withstanding any hostile assault. When the French approached the city, in the spring of the year 1799, a few wretched low towers, mounted with lUsty iron cannon, some of which burst every time a round was fired, constituted its whole defence. In these, the pacha Djezzar, who had already evacuated CaifTa, placed so little confidence, that he was preparing to make good his retreat, and to convey to some place of security his women and treasure, when sir Sydney Smith anchored with his squadron in the road of Caiffa, and sent colonel Philipcaux, a French engineer, to assist the pacha in fortifying the town. Djezzar, thus encou- raged, determined to hold out to the last. Caiffa was occupied by the French advanced guard, commanded by Klebcr, and the investment of Acre was completed by Bonaparte. But all their exertions, extraordinary as they were, were baffled by the vigilance, the activity, and the valour of sir Sydney Smith. In vain did they try every variety of attack. The garrison, assisted by the English marines, repulsed them on every occasion with great slaughter; and, after sustaining many irre- parable losses, particularly of his battering pieces and stores, Bonaparte announced to the army his intention of raising the siege. Accordingly, he began his retreat on the 20th of May, the sixty-first day after breaking the ground. On this occasion uncommon spirit was dis- played, and wonderful achievements performed, both by the besieged and their assailants; but on both sides cruelties were committed, and distresses endured, which humanity shudders on recollecting. Acre, possessed of every natural advantage, is daily increasing in prosperity. Corn and cotton are the staple articles of its conunerce ; but the trade has lately been monopolized by the pacha, without any exception even hi favour of the European merchants. The French had six mercantile houses in Acre, over which a consul pre- sided ; and Russia has recently established here a resi- dent. Acre is situated 27 miles south of Tyre, and about 70 miles north of Jerusalem; in Lat. 32" 40' N. Lon. 39" 25' E. See Hume's Hist. vol. ii. p. 14, 23.

ACRIDOPHAGI, from xy-qm, lucusi, and tpxyu, to cat, a nation so denominated by the ancients from the nature of their food. The exact situation of their coun- try is not ascertained, whence many of the moderns have considered their existence as entirely fabidous. It is pi-obable, however, that this incredulity lias, in a great measure, arisen from an invincible repugnance to be- lieve that an animal, which has ever been the type of pestilence and destruction, should at any time have been used in sustaining life. The most distinct account of the Acridophagi is given by Diodorus Siculus, who de- scribes them as " an Ethiopian nation, veiy black, of meagre person, and small stature. They were so short lived, that their life never exceeded forty years; and they generally died a wretched death. Winged insects, of a hideous form, were generated in their bodies, be- ginning in the breast and belly, and gradually spreading over the whole Trame. Excruciating torments, attended with effusions of putrid blood, were occasioned by these animals when forcing their way through the skin ; and the miserable sufferer uttering lamentable cries, made way for them with his nails. At length he expired, hav- ing his body covered with innumerable ulcers. During spring, when the warm west winds drive immense swarms of locusts among the Acridophagi, they set fire to wood and other combustibles in a steep and extensive valley, and the flight of locusts in passing over it, were suffocated by the smoke. They were then collected in heaps, and salted for future use." Strabo coincides with Diodorus in assigning the same country to the Acridophagi. Agatharcides, a Greek historian, who lived prior to the time both of Strabo and Diodorus, also places tliem in Etliiopia, though appa- rently in a different part of that extensive country. Ac- cording to Pliny, the Parthians fed on locusts, which he infers was not in consequence of scarcity, as they abound- ed in wealth ; and the females full of eggs were preferred, .ffilian, the naturalist, says, they were sold in Egypt for food ; and various Greek authors mention, that they were used as sustenance by the lowest orders in Greece. But if Aristophanes and Athenaeus mean tliis identical animal, at one time it seems to have been sought after as a delicacy and publicly sold. St Jcrom, who lived in the fifth century, speaks of the "Orientals and inha- bitants of Libya eating locusts, where they appear in im- mense clouds." Several other ancient authors agree in asserting, that these animals were an article of food in various nations. The same custom has been transmitted to the present day. Locusts are used as food by different tribes of Arabia, who even catch them in great quantities, and bring them to the public markets for sale. Niebuhr. 126 ACR ACT the Danisli travellep, observes, that the locust arrives lean and emaciated, and that it is only after it has fatten- ed on the herbage, that the Arabs consider it a delicacy ; and the female, when full of eggs, is thought an invigo- rating food for men. The Jews, as well as the Arabs, eat them. Ur Shaw compares the taste of the locusts of Barbary, where they are also eaten, to that of era) -fish. Hasselquist, a pupil of the celebrated Linnaeus, during his travels in Syria and Egypt, learned, that the Arabs and Ethiopians ate locusts ; and, when a scarcity pre- vailed at Mecca, that they were bruised in mortars, and baked into cakes, which were used as bread ; and that they were likewise eaten when there was no scarcity, though prepared in a different manner. Sparrmann in- forms us, that the Hottentots feed on the immense swarms of locusts that appear at different intervals, and chiefly prefer the females, which are more easily caught from the shortness of their wings, and the distention of their bodies with eggs. All these facts are confirmed by other travellers, whence there is no doubt that both ancient and modern nations have fed on locusts ; and the various modes in which they arc yet prepared, may vie with the nicest refinements of European luxury. Hence it is obvious, that the passage of scripture which states that St John fed on locusts in the wilder- ness, which has often been the subject of commentary, involves no obscurity, except that which ignorance of ancient customs has thrown over it. For although some have supposed, that his food was the tops of certain plants, and others have thought that the words transla- ted locusts here signifies quails, nothing but the literal interpretation of the words is required for understand- ing the passage.

(y") ACTION, a term of the Roman law, adopted into that of all modern states, which is thus explained in the In- stitutes of Justinian: — '■'■Actio nihil aliud est tjuam jus persequendi quod sibi debetur." The mode of obtaining justice, among the Romans, was to summon the defender into court, which the pur- suer, or plaintiff", might do verbally ; and if he failed ia compliance, he might force him into the presence of the magistrate. Sureties were then given for appearance on a certain day. The parlies having come into court, the plaintiff stated his cause before the praetor, in a certain form of words, which varied only according to the nature of the action. The praetor immediately appointed judges to deteiTiiine the point. The litigants had next to find sureties to fulfil the judgment, whatever it might be, to each other. The cause was decided, after the judges had taken a solemn oath to preserve impartiality. Actions were divided into real, personal, and mixed, and each of these classes branched out into numerous ACT ACT 127 subdivisions. See Ju.itinian. Instil, lib. iv. tit. 4 ; aild Gibbon's Hint. chap. xliv. vol. viii. p. 75. (r) ^ ACTION, in Mechanics, is, properly speaking, the motion which one body either produces, or lends to pro- duce, in another body; though it lias been generally employed to denote tlie effect 'which one power exerts agamst another power. The PrincifiU' uf least Action, was a name given by Maupcrtuis to the law, tliat when any bodies, acting upon one another, suffer any cliange in their motion, tlie mass, multiplied by the space and the velocity, or the quantity ol" action which nature employs to effect this change, is the least possible. This principle was attacked, as false, by Koenig, a professor at the Hague, who also maintamcd, that Leibnitz had described the .same principle in ITu", in a letter to Herman. This attack gave rise to a long and keen dispute, in which the Academy of Berlin interfered in behalf of their pre- sident. The principle of least action was extended by Euler, who proved, " that, in the trajectoris described by means of central forces, the product of the integral of the velocity, and the clement of the curve, is either a minimum or a maximum." This new law, which Euler j-ecogniscd only in the case of insulated bodies, was still farther generalized by La Grange, who found, " that the sum of the products of the masses by the integrals of the velocities, multiplied by the elements of the spaces, is always a minimum or a maximum." This principle has been employed by La Grange with great success, in the solution of many difficult dynamical problenis. See Mem. Acad.

See Mechanics, (to) ACTION, in Oratory, the adaption of the gestures and attitudes of the body to the tlioughts and feelings of the mind, intended to be conveyed by the speaker. There is always a sympathy between the body and the mind, and the one cannot be powerfully affected without a corresponding change taking place in the other. A powerful emotion becomes immediately manifest by its effects upon the voice, countenance, and gestures of the person who feels it; and if these appropriate effects of strong feeling are not discernible, we find it difficult to persuade ourselves that strong feeling is really excited, but are disposed to think that it is only dissembled. Pleads he in earnest ? Look upon his face ; His eyes do drop no tears ; his prayers are jest ; His words come from his mouth ; cms fi'om our breast ; We pray with heart and soul. — Shakspeare. There is something contagious in the appropriate looks and gestures of emotion ; insomuch that tlie most ordinary matter uttered with just action will make a deep impression upon an audience, when matter greatly more valuable, if delivered without this advantage, will be hardly listened to. The effect of pantomime exhibi- tions powerfully illustrates this, and shows that sfieaking is but one department of oi-atory. It is well known, that the greatest of orators, Demosthenes, placed the first, second, and third perfection of an accomplished speaker in c/oczord Carleton ; and it procured lor him the office of commissioner of the appeals, in which appointment he succeeded Mr Locke. In this poem is the well-known simile of the angel. He was soon after chosen under-secretary of state, first to sir Charles Hedges, and then to the earl of Sunderland,' About this time, he wrote the opera of Rosamond, which met with neglect, and hisses on the stage ; but he af- terwards published it with better fortune, and showed ei- ther his want of judgment, or his servile absurdity, by inscribing it to the dutchess of Marlborough, "a woman, without skill or pretensions to skill, in poetry or litera- ture." He went into Ireland in the year 1709, as secretary to the infamous earl ol Wharton ; and was, at the same time, appointed keeper of the records in Bermingham's Tower, with an allowance augmented for his accom- modation to 3001. per annum. Though a keen Whig, he could not be prevailed upon to relinquish his in- timacy with Swift, who held the sentiments of the Tories, and attached himself to that party. But his acceptance of favours from lord Wharton, by no means implies an approbation of his crimes : and it will not be an easy matter to find in any history, two associates of charac- ters so directly opposite, as those of Addison and Whar- ton. When he was in office, he never remitted his fees in civility to his friends ; " for," said he, " I may have a hundred friends, and if my fee be two guineas, I shall, by relinquishing my right, lose two hundred guineas, and no friend gain more than two : there is, therefore, no proportion between the good imparted, and the evil suffered." Whether this reasoning be just or not, it is certain, that, in his official capacity, he never indulged his friends by any gratuitous services : and throughout his life, he appears to have known the value of money, and to have had pretty exact ideas of the duty of pay- ment, when the fixed time was come. But while this is mentioned, let it not be forgotten, that he established it as a rule for himself, not to take, on any pretence, morn than the usual fees of his office. He was reserved and silent before strangers, and so timorous, that Chesterfield declares he -(vas the most 134 ADDISON. awkward man he ever saw : but he was easy, fluent, and familiar, in tiic company of his triends. Pope, who had Komc good reasons to view the character ol Addison in an untavouralile light, bears testimony to the seducing charms of liis conversation. He was jealous of a rival in wit. Steele was not of sufficient dignity to occupy much of his attention, or draw forth his censure ; but the growing reputation of Pope, touched the sensibility of liis pride ; and led him to support the pre-eminence to which he fancied he was raised, by means, of which honour and openness could not readily approve. It was his practice to study all the mornhig, to dme at a tavern, und to spend the evci.ing at Button's, a coffee-house, frequented by all who had pretensions to wit in those times. At the tavern, he drank too much wine. In politics, though sufficiently in earnest, he was not vio- lent ; and was respected, if not beloved, by individuals of both parties, which at that time agitated the state. When Swift slept forth as the champion of the Tories, his intimacy with Addison was not so close as before: yet they still maintained a regard for the virtues and talents of each other. See the Journal to Stella. While Addison was in Ireland, Steele began the 7a?- /('»-, a series of essays on literature and manners; the first of which appeared on the 12th of April, 1709. These essays were published without the name of the author; but Addison discovered them to be Steele's, by the use which the latter had made of a criticism on Vir- gil, which he had communicated to him some time be- fore. No sooner was this discovery made, than Addi- son became a contributor to the paper. The Tatler was succeeded by the S/ieclator; the first number of which appeared on the first of March, 1711: and such was the exuberance of matter, of which its authors had the choice, that it was continued daily till it extended to seven volumes, the seventh being completed on the 8th of December, 1712. In the year 1713, the tragedy of Cato was represented on the stage. This tragedy was known to be the production of a Whig, and was zealously applauded by those who belonged to that party : every line, which was favourable to liberty, was received with tumultuous approbation; and the approbation was echo- ed by the Tories, in order to show, that they did not feel the censure, which it was supposed to convey. Lord Bolingbroke called the actor, who personated Cato, to his box, and gave him fifty guineas, for having so ably supported the cause of freedom against the encroach- ments and the violence of a perpetual dictator. After tlie representation of Cato, the Guardian, another pe- riodical paper, was undertaken by Steele ; and to this also Mr Addison contributed, but not so regularly as to the Tatier and the Spectator. The popularity of these papers was deservedly very high ; and, though no longer supported by party, or recommended by novelty, they yet stand at the head of English literature, and will be perused with benefit and delight while the English con- tinues to be acknowledged as a separate tongue. This pre-eminence they owe chiefly to the genius of Addison. His essays in the Spectator are marked by one of the letters in the name Clio, and in the Guardian by n /land, characters which he employed to distinguish his com- positions from those of his associates. After the pub- lication of the Guardian, the Spectator was revived, and Addison contributed, as before, without using, however, any marks by which his papers could be known. An eighth volume was now completed. About the same tjnie, he meditated a dictionary of the English language, and proceeded some length in the definition of words, and the collection of authorities; but the number of his political avocations prevented tlie final execution of hi.s purpose, and the work has since been perfonned by Dr Johnson, with great ability, and with no little success. The H'liiff Examiner was written about tlic time when Cato was brought upon the stage ; and some other po- litical papers, of which Addison was the author, are re- ferred to the same period. The freeholder, the last of the periodical publications in which he was engaged, and which was designed to support the established go- vernment, appeared in the year 1715. In the year 1716, he married the countess dowager of Warwick, to whose son he had been tutor. The lady was not to be won but after a long and anxious court- ship; and showed, when she granted him her hand, that she was abundantly persuaded of her condescension in taking him for a husband. The marriage by no means increased the happiness of Addison. She never forgot her rank, and seems to have formed an opinion, which is not uncommon, that no culture of intellect, or exaltation of genius, can make up for the want of coronets and an- cestry. The majestic and repulsive behaviour of the countess often drove him from her society to a tavern, and made him veiy unwilling to return to her when he was there. It is certain, as Johnson remarks, that Addi- son has left behind him no encouragement to ambitious love. The year after his marriage, he was appointed secre- tary of state, and reached his highest preferment. It is generally acknowledged, that he was unfit for the duties of his place, and that he could not issue an order with- out losing his time in quest of elegant expressions, a solicitude which never left him in any of his writings. He shortly after retired from his office with a pension of 1500/. and devoted himself to literary pursuits. As his mind was turned to piety, he wrote the Evidences of the Christian Religion, vih'ich he intended as an antidote to infidelity; and he designed a new version of the book of Psalms. He projected also a tragedy on the death of Socrates. He relapsed however into politics, and wrote the Old Jl'hig-, with remarks on the Plebeian, which he either knew, or soon discovered, to be the production of Steele. The comedy of the Drummer is like'wise ascribed to Addison. Prior to his death, which happened in the year 1719, he sent for lord Warwick, a young man of a loose and irregular life ; and when he desired, with great respect, to hear his last injunctions, Addison, grasping his hand, addressed him in these memorable words: — " I have sent for you, that you may see how a Christian can die." The eflect of this awful scene is not known, as the earl died soon alter. Such a death as Addison's might have been expected from a life, approaching as near to per- fection as the weakness of human nature will allow. It is related of him, that he received encouragement from a married lady, of whom he had been enamoured ; and that he had the virtue to resist the temptation. The struggle, however, must have been great, for he was several times in love. He refused a gratification of 300/. and a ring from major Dunbar, whom he had endeavour- ed to serve : and when Mr Temple Stanyan had borrow- ed 500/, of him, and yielded to him, in an argument, with too great obsequiousness, he said to him : — " Either contradict me, sir, or pay me the money." After the death of Addison, Tickell wrote a poem t« the memory of his friend and patron, which he addressed ADD ADE 1^ to the earl oi' Warwick, and which Johnson, who seldom praises where praise is not deserved, pronounces to be one of the most noble and interesting of funeral compo- sitions in the whole circle of English literature. The following paragraphs are particularly recommended by the last mentioned writer : To strew ficsli laurels let the task be mine, A frequent pilgrini at tlic sacred slirine ; Mine witli true sijflis tiiy absence to bemoan, And jp-ave witli (aitliful epitaphs thy stone.

Proud names, who once the reins of empire held, In arms who triumplied, or in arts excelled ; Chiefs graced with scars, and prodigal of blood ; Stern patriots, wlio for sacred freedom stood ; Just men, by whom impartial laws were given ; And saints, who taught and led the way to heaven. Ne'er to these chambers, wliere the mighty rest Since their foundation, came a nobler guest ; Nor e'er was to the bowers of bliss convejed A fairer spirit, or more welcome shade. The chief works of Mr Addison are the tragedy of Cato; his papers in the Tatler, the Spectator, and the Guardian; and the Evidences of the Christian Religion. The tragedy of Cato is the reverse of a true copy from nature. The incidents are such as seldom occur in real life, and are therefore but little calculated to in- terest the attention ; but tlie principal character is well supported, and the poetry is fine. Cato's soliloquy on the immortality of the soul may be selected as one of the most dignified and elegant compositions in the Eng- lish tongue. In writing this tragedy, he was confined by narrow ideas on the subject of the unities of time and place, as Dennis has shown with malevolent acuteness ; ajid its moral tendency may be questioned, as Cato not only falls before the power of a tyrant, but takes away his own life. In his other poems, some of which appear to have been executed with care, there is little either to blame or to praise. Addison's papers, in the Tatler, the Spectator, and the Guardian, may be divided into the comic, the se- rious, and the critical. His humour is peculiar to himself. He employed his wit against the approaches of scepticism and immorality; and such is the force of good example, that, since his time, it has generally been found in alliance with truth and virtue. His court of honour in tlie Tatler, and the papers relating to sir Roger de Coverley in the Spec- tator, may be selected as the best specimens of his comic powers. For easy and delicate satire they are perhaps unequalled in any language. Addison has risen " above all Greek, above all Roman fame." His serious papers. Which are written with a beauty and propriety of lan- guage not inferior to any thing in his comic productions, were uniformly designed to ameliorate the dispositions, and to reform the conduct, of his readers; and it cannot be denied, that they had the effect which they were meant to have, and that such as perused them were ren- dered not only wiser, but better than they were before. He recommended knowjcdge to those who were not of tlie learned professions, at a time when ignorance was considered as no disgrace; and he taught the females of his days, that they had minds as well as those of the opposite sex, and that these minds deserved to l>e culti- vated and improved. He may safely be regarded, as one of those who have contributed most to change us into a nation of readers. He has been called a bad cri- tic; but they, who censure him, should remember, that he was the first who exhibited the canons of criticism in an easy and popular manner, and enabled those to judge of poetry who were not so desirous of profound know- ledge, as of sufficient information to qualify themselves for talking ol the rules by whicli books ought to ber written. He did not publish a system of criticism ; but what he ofl'ered was just. The precepts of the ancients had remained concealed in the poetics of Aristotle, or scattered over the irregular prefaces of Drydcn, till Ad- dison gave to the general reader his observations on the Paradise Lost. And so preferable are ease and elegance of composition to the system and deep investigations of science, that Milton was brought into universal notice, and became the favourite of all who had pretensions to literature : for, besides the inherent excellence of the poem, all were pleased with what had been so agreeably recommended to their approbation. He descended, how- ever, " in a dying fall," from the epic dignity, and wrote comments on th» ballad of Chevy Chase, which were read, only because they were of his writing. No quota- tions from Virgil, and of these he employed not a few, could make the world believe, that the story was cither very interesting in itself, or told in such a way as t» give pleasure to the reader. It may be said of his " Evidences of the Christian Religion," that they were well intended, and that they may be perused with advantage by those who have not time to read larger treatises : but, as the subject has engaged the attention of others, since Addison wrote, they are inferior to the works of Paley and Beattie, and the Apologies of Watson ; men, who stood forth in de- fence of Christianity, when it was attacked by the impu- dence of Paine, the wit of Voltaire, and the subtle insi- nuations of the historian of the Decline and Fall of the Roman Empire, (/i) ADDITIONS, in Heraldry, are a species of bearings in coats of arms, in which additional marks of honour are placed.

See Anatomy, (f) ADEL, or Adea, a kingdom of Africa, bounded on the east by the Indian ocean; on the north, by the Red Sea, the straits of Babelmandeb, and Cape Guardnfui ; on the south, by the kingdom of Magadoxa; and on the west, by the country of the Galla, or the kingdoms of Dancali, Dawaro, Bali, Fatigar, and other districts of Abyssinia. Its extent, though not exactly ascertained, is supposed to be about 160 leagues from east to west, and about 72 from north to south. Adel, the capita!, from which the kingdom has received its name, is situ- ated near the river Hawash, about 300 miles south of Jlochti in ArabiE ; N. Lat. 8° 5'. E. Long. 44° 20'. This 136 AJ3E ADE kingdom is bomcliines called ZeMa, irom un cniLienl sea-port of that name. It is said to have been first- erected into a separate kingdom, aboit the beginning oi" the 16th century, by Salatru, a prince of Abyssinia, who, iiaving escaped from the prison, in which the rt^al fa- mily, accorcling to the custom of that country, was con- lined, took refuge in Adel, then an Abyssinian province ; and marrying the daughter of the king of Zeila, became independent sovereign of these united kingdoms. The kings of Adel are the most formidable enemies with whom the monarchs of Abyssinia have to contend. As the Adelians arc Mahommedans, and the Abyssinians profess Christianity, their mutual jealousy of each other's power is heightened by the rancour of religious 2eal; and the wars, in which the two nations are almost perpetually engaged, are marked with every atrocity, which might be expected from the rivalship and enthu- siasm of savages. For their hatred against the Chris- tians, and their zeal in the cause of the Prophet, the kings of Adel are in great favour witli the Grand Sig- nior, to whom they are tributary, and are dignified witli the appellation of saints. In exchange for this flattering title, the sultans have appropriated to themselves the most considerable maritime towns of the Adelians ; so that all their ports, except Zeila, are now occupied by the Turks. The interior of this kingdom is little known to Euro- peans. Towards the south-east, the whole coast is a de- sert : but in the rest of the country, the soil, composed of rich black earth, washed down by torrents from Abyssinia, is extremely luxuriant. It produces wheat, barley, and millet in abundance ; and pastures numerous flocks and herds. We are informed by Hamilton and Barthema, that sheep arc found at Adel entirely white, witli the head of a brilliant black, and with very small ears. The sheep of Adel are said to have their neck swollen by a kind of dewlap hanging down to the ground, which demonstrates the identity of the species with the ram upon ancient marbles represented by Fabroni, and proves that this species exists in Europe, Asia, and Africa. Some of these sheep are remarkable for the size of their tails, which sometimes weigh 25 pounds, and their wool is almost as hard as the bristles of a hog. The principal articles of commerce are gold-dust, ivory, frankincense, and negro slaves, which are ex- changed for the merchandise of Arabia and the In- dies. The inhabitants, called Gibbertis, are a stout and war- like people ; those on the northern coast are of a tawny brown complexion ; and those towards the south are of a deeper black. Their principal towns, besides Adel and Zeila already mentioned, are Barbara, a place of considerable trade ; A/f/a, on the northern coast, near the river Soal; Asscm, on the east, which supplies the mariners with provisions ; and Cape G ttardafui, xxj \.he. north of Assem. It seldom rains in this country ; but the soil is irrigated by many rivers and canals. The climate is intensely hot, feverish, unhealthy, and gene- rally fatal to strangers. Walknaer's Geog. notes.

A fine aqueduct conveys water from the same mountains into a lai'ge reservoir, or canal, about three quarters of a mile from the city. Aden, from the excellence and advantageous situation of its harbour, which opened an easy communication with Egypt, Ethiopia, India, and Persia, was, for many ages, one of the most celebrated marts, and most flourishing factories, in Asia. In 1513, it bafiled the attempts of Albuquerque, the Portuguese admiral, who wished to demolish it; but in 1559, Solyman II. treacherously seized the sovereign of Aden, and obtained possession of the city. The Turks were soon expelled in their turn by the king of Yemen, who removed the trade of Aden to Mocha, till that time an inconsiderable village. Aden is now almost a heap of ruins, with two mosques and minarets ; but as the kingdom of Mocha is torn to pieces by the Wahabees, Aden will probably recover its commercial importance. Banians from Mocha reside here to carry on the trade, with Berbera, and buy up the myrrh and gum-arabic brought by die Samaulies. Cape Aden is a lofty rock, with several ruined towers. N.

(rf) ADHERENCE, Action of, in the Scottish law, is an action at the instance of a husband, or wife, to com- pel either party to adhere in case of desertion. The sen- tence of adherence may be enforced by letters of horn- ing; and, if the offender disobey, the act 1575, c. 55. directs the church to admonish him, and in case of far- ther disobedience to excommunicate him. This action does not seem to be competent when the party is out of the kingdom. Sec Bell's JJict. oj the Law of Scotland, vol. i. p. 10. (to) ADHESION, or Adherence, from at/ and Jixreo, to stick, is properly the condition of two separate bodies, ivhcn they are held together by the mutual attraction of llieir particles. It is generally employed to denote the force by which the surfaces of solids adhere to the surfaces of fluids, in consequence of their mutual at- traction. Our countryman Dr B. Taylor seems to have been the first who made this branch of physics a subject of in- vestigation. He observed so early as 1713, the ascent of water between two glass plates, and from his expe- riments on the adhesion of surfaces, he concluded, that the adhesive force might be measured by the weight which was necessary to separate the contiguous sur- faces. He found, that a square inch of wood required fifty grains to raise it, and that the adhesive force was always in the direct ratio of the surface in contact with the fluid. It was the opinion of some other philoso- phers, that this adhesion was owing to atmospherical pressure, and therefore no new experiments were in- stituted till 1773, when M. Guyton Morveau investigat- ed the subject with the greatest ardour and success. He suspended a polished disc of glass, thirty lines in dia- meter, to the arm of a balance, and found that a weight of nine gross, and a few grains, was necessary to separate it from the surface ofmercuiy. The apparatus was then placed in the exhausted receiver of an air-pump, and the same counterpoise, as before, was necessary to dis- unite the mercury and glass. This experiment, which clearly showed that the pressure of the air was not the cause of adhesion, was followed by a variety of others, from which Morveau obtained very interesting results. The metals which he employed, were in the greatest purity; they were each an inch in diameter, well polish- ed, and of the same thickness, and had a small, ring in Vol. I. Part I. ADIl 137 tlieif cejilrc, by which they were suspended at the arm of an assay balance. With this apparatus, he obtained tlie following results. Metals empl())ed. Gold, . . Silver, . . Tin, . .

The adhesive force of each metal seems to be proportional to its solubility in mercury ; and therefore the numbers which express that force in the different metals, maybe regarded as an approxima- tion towards the ratio of the relative affinities of the me- tals for mercuiy. Dr Taylor's method of ascertaining the force of adhe- sion was also employed by Mr Achard of Berlin, who has made an immense number of interesting experi- ments upon this subject. By varying the atmospherical pressure, he found no change in the adhesive force of glass and water; but when fluids of diff'erent tempera- tures were employed, he found that their adhesion to so- lids was uniformly in the inverse ratio of the temperature. The relation between the adhesion of glass, and the temperature of \'\ater, he expresses by an equation similar 1 fi ^ to the following : e = 530 a, or a = 99.33 —t i 3 16 and the table which Mr Achard has computed from these formulae for different degrees of Sulzer's thermometer, accords wonderfully with the experimental results. From these results, it appears that for every additional degree of heat of Sulzer's thermometer, (equal to 1.1565 of Fahrenheit,) the adhesive force diminishes 0.1858 grains according to experiment, or ^J ^ of a graia for every degree of Fahrenheit ; and 0.1876 according' to calculation. This diminution in the force of adhesion is ascribed by Morveau to the diminution cf the fluid's density in consequence of its rarefaction by heat, from which it happens that the disc of glass comes in con- tact with fewer points of the fluid. In order to ascertain the relation between the adhesive force and the area of the surface of the solid that is brought into contact with the fluid, Mr Achard em- ployed discs of glass, from 1.5 to 7 inches in diameter, and found that the force was in the direct ratio of the squares of the surfaces. When the experiments were made with various fluids, viz. distilled water, sulphuric acid, concentrated vinegai-, alcohol, acetile of lead, acetite of copper, deliquiated potash, ammonia, sulphuric ether, oil of turpentine, and oil of almonds, Mr Achard found that with al- most all these fluids, lead and brass had the greatest adhesion ; and wax and sulphur an adhesion greater than any of the other metals. The adhesion of gypsum was the least in all the fluids, except the sulphuric acid, to which it adhered with greater force than any of the other discs. .138 ADl AJ)I The subject of adliesion has been ubiy discussed by M. Diitour in the Journal de Physhjuc. He shows, that the method employed by Taylor and Achard to estimate the adhesive force, is correct only when the solid rises from the fluid surface, without bringini^ along with it any of the fluid particles, as in the case of glass and mercu- ry ; for when the solid brings along wiih it a quantity of the fluid, as in the case of glass and water, mercury, and some of the metals, the solid docs not separate from the fluid at the plane of adhesion, but a little below it, in a plane lying in the substance of the fluid ; so that the weight which produces this separation is rather an ex- pression of the cohesion between the particles of the fluid, than of the adhesion of the solid. M. Dutour also obtained the following results : A disc of 72 square lines French, adhered to Water with a force of SI gr. Fr.

In consequence of the feuds which prevailed among the Seleucidae, Adiabene was erected into a separate kingdom, and was governed by successive sovereigns in opposition to the kings of Syria, till it became subject to the Roman emperors. In the reign of Trajan, the Adiabenians joined Chos- roes, king of Persia, then at war with the Romans. Trajan having obtained possession of Adcnystrse, one of •their sti'ongest forts, transported his army over the Ti- gris by means of a bridge of boats, and made himself master of the whole kingdom of Adiabene in the 115th yearof the Christian era.

This substance was discovered at Paris in 1787, when the burving ground of the church des Innucens was re- moved on account of its insalubrity; and tiie space wnich it occupied laid out for buildings. Tiiis burying ground had been for many centuries the receptacle of the dead in one of the most populous districts of Paris, and con- tained several large cavities (./bsscs fo«;mu«f«) about 30 feet deep, and 20 feet square. Each of these immense pits which had been heaped above their natural level, contained about 1500 adjacent coffins, enclosing the bo- dies of the poorer inhabitants, who were un.ibrmiy doom- ed to this species of dishonourable interment, so that a space of nearly 200,000 cubic yards was completely fil- led with one hideous mass of corruption. When the proposed alterations on this part of the city wei-e to be put in execution, it became necessary to remove the greater part of tlie soil with its putrid contents ; and it was during this operation, that Messrs Fourcroy and Thouret obtained the following interesting facts. In one of the pits which had been filled up about IS years, the bodies had sunk to the bottom of the coffins, as if they had been flattened by the pressure of some weight; and upon removing the linen shroud, there ap- peared irregular masses of a soft unctuous substance like cheese, of a brownish colour, and apparently inter- mediate between wax and fat. After further examina- tion, it appeared that this adipocire was composed of every part of the body, except tlie bones, nails, and hair ; that it was generated in about three years; that it was more perfect in the centres of the pits, than in the parts nearer the surface ; that in the space of about 35 years, when the ground is dry, it becomes brittle, semitrans- parent, and of a granulated texture ; and that it was never produced when the bodies were interred singly. This singular substance may be also produced, and with greater rapidity, by immersing animal matter in running water. Dr Gibbes found, that part of a cow placed in the bottom of a stream, was converted into an adipocirous substance in about three months; and that the same conversion might be effected in the space of three days, by macerating the animal substance in di- luted iritroas acid>.

It is generally applied to a father who is empowered by law to manage the property of his children during their minority, (w) ADMIRAL from an-^^xXioi, which is again derived from the Arabic word yhiicer,a. prince, and uM, the sea, is a person who holds an office as a judge or president of a court for the trial of maritime causes, and the regu- lation of maritime affairs; and has the command, either of the whole navy, or of a portion of it. Neither the antiquity nor the early history of this of- fice is well ascertained. It has been thought by some writers, that the name is of eastern origin, and that it is derived from the Arabic word amir or e?nir, which signi- fies a commander, whether on land or sea ; but without inqt\iring into the foundation of this conjecture, it is evident, that such an office will gradually arise in every state as a navy begins to be formed. Du Cange assures us, that the Sicilians were the first by whom the title of admiral was adopted ; and says, that they took it from the eastern nations, who often visited them: and he, far- ther, gives the authority of Matthew Paris to show, that the Genoese were the next who applied the woi-d to the commander of a squadron. This appears to have been done in the time of the crusaders, and about the year 1244. History is silent with regard to the exact time when the name of this ofl'icer was introduced into England. Sir Henry Spelman, a learned antiquary, is of opinion, that it was not before the reign of Henry III : because it is not mentioned in the laws of Oleron, which were made in the year 1266, nor by Bracton, who was lord chief justice of England about the same time, in his treatise De Legibus et Consue'udinibus Jnglix. It is likely, that a term synonymous with that of admiral, and of equal or perhaps of greater antiquity, was used in remote pe- riods: as in later times, when the appellation of admiral was not known, or not employed, tlie commander of tlic fleet appears to have had liie name ol cuerotunarin ; and sometimes tiiat oi ca/iitancuti marilimarnm. There were anciently three oi- lour admirals of tlie English seas, who all held their offices durnig the pleasure of the king: and besides these, there were admirals of the C'inrjuv Ports ; one of whom (William Latimer) is des< rihed as .idmiralis quirKjue portuuw, in the reign of Edward III. The title of ^dmiralis ylnglia, or high admiral of Eng- land, was first given to the carl of Arundel and Surrey, by a patent of Richard II. in the year 1387: but it was not a titLs of tre(|uent application tUl the reign of his suc- cessor Henry IV. The same title was afterwards con- ferred upon other subjects, generally of the highest rank ; though it has now been discontinued for many years, and simk in that of the lords commissioners of the admiralty. The king's lieutenant upon the high seas, locum tenen.9 regis su/ier mare, was an officer of superior dignity to the admiral of England. It is always in the power of the king to appoint a higli admiral ; and when that power is exercised, the officev who is thus appointed has always the sole direction of maritime affairs. The royal navy is under his govern- ment and command : and he nominates the inferior ad- mirals, captains, and, in general, all who serve in it, whether by virtue of commissions or of warrants. He has likewise a civil and criminal jurisdiction in all ma- ritime cases ; including transactions which take place in arms of the sea, and on the rivers which flow into it, up to the first bridge. This power extends over all sailors ; both those who are in actual service, and those who may be living on shore : and, throughout the king- dom, he may forcibly apprehend the latter, and employ them in the ships of war. He presides in the court of ad- miralty : and when offenders are convicted of capital crimes, he has the appointment of every thing which relates to their execution. The emoluments of the lord high admiral are very considerable. He had for- merly a right to the tenth part of all prize goods ; but that right was abolished by statute in the reign of George II. (13 Geo. II. c. 4.) He is still however, en- titled to all fines or forfeitures in consequence of trans- gressions at sea, in ports or havens, and within high water mark ; though between high and low water mark, the admiral and common law bear rule alternately, the one upon the land, and the other upon the water. The administration of this important office has, for a considerable time past, been intrusted to six lords com- missioners of the admiralty, who, by a statute of Wil- liam and Mary, (W. and M. stat. ii. c. 2.) are vested with the same authority, jurisdiction, and privileges, which the lord high admiral formerly enjoyed. The first lord is ahvays a member of the cabinet, and en- grosses the whole prerogatives; as his colleagues have few or none. Petitions or applications to the king in council, are only so in fiction, as no discussion of tlicm ever takes place; and they are immediately transmitted to the admiralty, where the lords commissioners, oe more properly the first lord, decides upon the nature and subject of the application. Though Scotland never possessed any thing which could merit the appellation of a navy, there was former- ly a lord high admiral in tliis country. It is difficult to collect much of his early history ; but extensive powers were conferred upon him by an act which was passed m s e 140 AliM ADM the year 16jl, and in which he is styled "ilic king's lieutenant and justice-general upon the seas." His of- fice is now absorbed in that of the lords commissioners of the admiralty for Great Britain. A vice-admiral, however, is still appointed by the crown, and exercises a civil and criminal jurisdiction in Scotland, nearly of the same kind wiUi that which belonged to the high-ad- miral of England. It is not many years since a person accused of robbery on the seas was tried beiore the vice-admiral, and a jury in the former country, and sen- tenced to be hanged at Leith wilhin high w.iter mark. But the duty of the office is now generally done by a «leputy, who is called the judge-admiral, and presides in a court for the discussion of maritime questions.* Admiral is also the title given to the highest rank of officers in the British navy. There are admirals of the red, white, and blue : and there are also vice-admirals and rear-admirals of each of these flags. An admiral carries his flag at the main-topmast head ; a vice-admi- ral at the fore-topmast-head, and a rear-admiral at the mizen-topmast-head. (c) ADMIRALTY, Coukt of, a supreme court, held by the lord high admiral, or the lords conmiissioners oi the admiralty, for the trial of maritime causes, whether of a civil or of a criminal nature ; and which is not a court of record. It was instituted by Edward III. It takes cognisance by judge and jury, of all criminal offences upon the high seas, or on the shores of any country under the dominion of Great Britain ; but in civil cases, the mode is different, and the discussions follow the prac- tice of the civil law. It is enacted, that in criminal tases, felons shall be tried in the presence of a jury by commissioners, whom the lord chancellor has the right ef appointing ; and those commissioners are the judges of the court of admiralty : but besides these, there are three or four others, two of whom must always be taken from the number of supreme judges. An appeal to the sovereign in chancery lies (8 Eliz. c. 5.) from the sen- tence of the court of admiralty. There are likewise courts of an inferior nature held by the admirals deriving their appointments from the supreme court, or the judge-admiral of Scotland, witliin their respective jurisdictions ; and an appeal lies from their decisions to the supreme court. But in the case of prize vessels, taken in any pai-t of the world during war, the appeal lies to certain commissioners of appeals, who are chiefly of the privy council. t (f ) * In the United States there is no office correspon- ding to that of lord high admiral in England ; the pre- sident is by the constitution commander in chief of the anny and navy of the union, and the secretary of the navy under him superintends the details of the latter department. DrroxcE.vu. t In the United States there is no court of admiralty expressly so called. The district courts, established in the different states under the authority of the federal government are vested by law with what are called ad- miralty powers, and have original cognisance of prize causes, and of those causes civil and maritime which are held in England to he within the jurisdiction of an instance court of admiralty.

Its situation is marked out by the Admiralty islands, which lie off in the strait, at some distance from the entrance ; and by an island two miles north-east of Cape Stephens, in S.

On each point of the harbour, which Vancouver named Penn's Cove, there was a deserted village, in which were found sepulchres in the form of sentry-boxes, con- taining small skeletons, and pieces of bone, which were supposed to have been used by the inhabitants for pointing their arrows and spears.

This island, which is about 60 leagues in circum- ference, has many convenient bays, fine streams of fresh water, and is covered witli an unmterrupted forest of fine trees, chiefly of the pine tribe, (k) ADMIRALTY Islands, a cluster of between twenty and thirty islands, lying to the north of New Britain, in about 2" 18' S.

Captam Carteret, by whom they were first discovered, described them as clothed with woods of beautiful verdure, luxuri- ous and lofty, interspersed with spots that have been cleared for plantations ; groves of cocoa-nut trees ; and houses of the natives, who seemed to be numerous. As the climate and latitude of these islands is the same with that of the Moluccas, captain Carteret thought it proba- ble, that they produce pines, and other valuable articles of trade ; but the frail state of his ship, and his want of the articles necessary for trading with the Indians, pre- vented him from landing to examine them. (A) trial is by exhibits and witnesses, without the interven- tion of a jury. From the district court an appeal lies to the circuit court, and from thence to the supreme court of the United States, which decides in the last resort. The district courts have also cognisance, as courts of criminal jurisdiction, of certain petty offences com- mitted on the high seas ; but the trial of piracy and in general of all crimes cognisable by a maritime court, the punishment of which exceeds thirty stripes, a fine of an hundred dollars, or an imprisonment of six months, belongs to the circuit court ; and tlie proceedings in such cases are according to the course of tlie common law. Causes of forfeiture in consequence of violations of the revenue or other prohibitory laws of the United States, are held with us to be within the admiralty branch of the jurisdiction of the district courts, provided the seizure has been made on the high seas, or on waters navigable by vessels of ten tons burthen ; and therefore such causes are heard and determined with- out a jury. It is otherwise if the seizure has been made on land, DtJi-ONCEAU. ADO ADO 141 ADOLESCENCE, the period of life between infancy and maniioou.

Many fine islands belong to it, which arc cover- ed with beautiful and populous villages. The situation of Adorn enables its inhabitants to intercept the commu- nication of the northern regions of Africa with the ne- groes of the coast; and they subject those v.ho carry on that intercourse to a duty, which yields a considera- ble revenue. The authority of the chief, which was for- merly arbitrary, is now controlled by five or six of the principal men, who, with the king, form the national council. See Dapper's Descrifition De C Afrique., p. 288. {k) ADONIA, solemn feasts in honour of Venus, and in memory of Adonis. They were annually celebrated, with peculiar solem- nity, in the temple of Venus at Byblos in Syria, at the season when the water of the river Adonis was changed into blood. This uncommon appearance, which afforded such a strong ground for superstition, was witnessed by Maundrell on the 17th of March, and is rationally ascribed by him to the effect of the preceding violent rains, washing down from the mountains a kind of red earth, by which the river was deeply tinged. (^Travels, p. 34.) The most particular account of this festival is given by Lucian, {de Dea Syria) a.a follows: — "The Syrians affirm, that what the boar is reported to have done against Adonis, was transacted in their country ; and in memory of this accident they, every year, beat themselves, and wail, and celebrate frantic rites ; and great lamentations are appointed throughout the coun- try. After this, they first perform funeral obsequies to Adonis, as to one dead, and on a following day, feign that he is alive, and ascended into the air or heaven ; and shave their heads, like the Egyptians at the death of Apis. Whatever women will not consent to be shaved, are obliged, by way of punishment, to prostitute them- selves during one day to strangers ; and the money thus earned is consecrated to Venus." Lucian adds, that " some of the Byblians conceived these rites to be performed in honour of Osiris the Egyptian deity, and not of Adonis." At the time of this feast, the Egyptians, according to Cyril as well as Lucian conveyed a box of rushes or pa- pyrus, with an enclosed letter, to the women of Byblos, informing them that their god Adonis, whom tliey ima- gined to be lost, was discovered. The vessel was thrown into the sea, and always arrived safe at Byblos, at the end of seven days ; and on receiving it, the wo- men ceased their mourning, sung his praises, and made rejoicings as if he were raised to life again. But Meur- sius says, that the two ceremonies of lamentation and rejoicing, were observed at the distance of six months from each other ; Adonis being supposed to pass half the year with Proserpine, and the other half with Venus. The one they called ca^aviT/M^, dua/i/icurancc^ and the other i^in'ii, return. These Adoiiia were celebrated at Alexanflria in the time of Cyril ; and at Antioch ill the time of Julian the apostate. They lasted two days ; on the first of which, certain images of Venus and Adonis were carried some times by tUe queen hcr.->elf m solemn funeral procession ; and the women wept, uttered lamen- tations, &c. This mourning was called Aiana.rfiL'x;. According to Julius I-'irmicus, (See CJodwin's Mosm and yJaron,p. 186.) on a certain nigiit during these solemni- ties, an image was laid on a bed, and after great lamen- tation made over it, li,i;-/n was brought in, and the priest anointing the mouths of tlie assistaiits, whispered to them with a soft voice, " 'J'ru.it ije in God, for out of distress deliverance has come to us ;" on which their sorrow was turned into joy, and the image taken as it were out of its sepulchre. Part of this ceremony is evi- dently-alluded to by Theocritus, IdijU. xv. 84, 85. Mythologists and learned divines have been much divided in opinion respecting the origin of these rites. From their researches, the identity of Adonis with Osi- ris seems to be as satisfactorily established as such a point can be. Plutarch says he was the same with Bac- chus. {Symjwsiac. lib. iv.) Thus also Ausonius iden- tifies him with both : Ogygia me Baccliuin canil ; Osinn jE^ypliis vocat : Arabica ^ens .'idumum. Proceeding on this supposition, bishop Patrick ascribes the origin of the Adonia to the slaughter of the first born in the time ot Moses ; conjecturing that the name of Pharaoh's eldest son, slain on that occasion, might be Osiris. Spencer {de Leg. Hcb. lib. 2. c. 37.) thinks, that the death of Osiris or Adonis, generally considered as the Sun, being the god that presided over the fruits of the earth, denoted their being separated from the earth in the time of harvest. Macrobius says, {Saturnal. lib. I. cap. 21.) that Adonis was undoubtedly the Sun ; and following Bryant's ety- mological system, Ad-On is one of the names of this lu- minary. On this principle, the two feasts in honour of Adonis, about September and March, might relate to the diminution of light during the winter months, and the increase of it during the summer months. From the resemblance between the rites of the Orphic Argonau- tica, and those mentioned by Julius Firmicus, others have supposed that they relate to the ^r^/Vc ceremonies, com- memorating tlic history of Noah and the deluge. See Plut. in Nicia. Ainmian. Marcell. 22. c. 9. Bryant'b Myth. vol. i. p. 371. Calmet's Diet. Frag. 317. {d) ADONIS, according to some writers, was the son of Cinyras, a king of the Assyrians, who founded Paphos in the isle of Cyprus. His Ijcauty was so exquisite, that Venus became enamoured of him, while yet in his in- fancy, and inti-usted Proserpine with the care of^his education. Proserpine refusing to restore him to Venus, Jupiter decreed, that he should live one-third of the year with each of the goddesses, and the other third be at his own disposal. Adonis, captivated with the charms of Venus, gave two-thirds of his time to her society. Diana, offended at this, sent a wild boar, which slew him, by wounding his thigh with its tusks. According to others, he was the incestuous son of Cinyras, by his daughter Myrrha. He was sent for concealment to the mountains, to be nursed by the nymphs, where Venus falling in love with him, admitted him to her embraces ; 142 ADO ADO and Mars, from jealousy and revenge, killed him, by iraiislonuing himsclt into a wild boar. Alter hib death, Vciiub obtained tliu conbcnl ol Proserpine, that lie should diviue his time between tlieni, and appointed an annu- al festival to commemorate this event. The dcalli of Adonis is the subject ol an extjuisitcly tender and beau- tiful elegy, by the poet liiou. Macrobius explains this fable ol the sun, represented by Adonis, passing tnrough the twelve signs ; Venus meaning the upper, and Pro- serpine the inferior hemisphere ol the earth, and the boar that slew him signifying the winter. (Hafurnal. lib. I. cap. 21.) Bryant supposes that the Caiiaanites wor- shipped their chief deity, the sun, under this title. For other mythological interpretations, sec Adosia. (f/) ADONIS, a river ot Phoenicia, rising in mount Liba- nus, or Lebanon, and called by the Turks Obrakim Ban- sa. At certain seasons of the year, especially about the time when the feast of Adonis was celebrated, the river is stained to surprising redness by a sort of minium, or red earth, washed down by the violence of the rains. This change of colour the heathens attributed to the fresh streaming of the blood of Adonis, " Whose annual wound in Lebanon, allured The Syrian damsels to lament his fate In amorous ditties all a summer's day : Wliile smooth Adonis, from his native rock, Kan purple to the sea ; supposed with blood Of Tliammuz yearly wounded."

See Botany, (to) ADONISTS, the name of a sect or party among the- ological critics, who maintain, that the vowel points com- monly annexed to the Hebrew word Jehovah^ neither originally belonged to it, nor express its true pronuncia- tion, but that they belong to the words Adonai and Elu- him, and were applied to the ineffable tetragrammaton Jehovah, to warn the readers, that, instead of this word, they are always to read Adonai. They are opposed to the Jeho-vists ; the principal of whom, are Drusius, Ca- pellus, Buxtorf, Altingius, and Reland ; which last has ptiblished a collection of their writings, (f/) ADOPTION, an act by which any one takes another into his family, owns him for his son, and appoints him his heir. The origin of it is obvious and natural. As the principle of lineal descent, and the influence of pa- rental affection, are peculiarly strong, it is reasonable to expect, that those, who have no children, will be solici- tous to obtain some object, on whom they may bestow .their love and propci'ty. Adoption has, accordingly, in one form or another, ex- isted in every age and country. This custom, as it re- £p6cte his son, provided the donee have rm inHUr, il tlic boy be ol ihe same class, and ailectionately disposcu, is a ton gi- ven by water, i. e. the gill behig eonleriid by the pour- ing oi water. He, who has no son, may appoint liis daugh- ter to raise up a son to him, by saying, tue maie cnild, WHO shall be born Irom her in wedlock, shall be mine, lor tne purpose ol performing my funeral obsecjuies. The soil ot a man is even as himscif ; anu as a son, sucU is a tiaugiiter thus appointed. Tne son of a daughter, appomteci as just mentioned, shall inherit the whole estate ol her fatlier, wlio leaves no son. Between the sons ol a son and of a daughter, thus appointed, there is no ditl'erence in law." The laws ot the Greeks and Romans, respecting adop- tion, were still more precise. Eunuchs were not allow- ed this privilege, as being incapable of begetting chil- dren ; and it was expressly required, that the adopter should be at least eighteen years older than his adop- tive son, that there might appear a probability ol his be- ing the natural father. By tlie Greeks it was termed uit'iii, JiUaiion, and was allowed to such as had no issue of their own, excepting to those who were notx^f/o; 'ici.v,m, thi.ir own masters ; as slaves, women, madmen, infants, or persons under twen- ty years of age. At Athens, foreigners had to be admit- ted to the freedom of the city, before they were capable of being adopted. Adoption was consummated by the form of a will, signed and sealed in the firesence of the ma- gistrate ; after which, the person, so adopted, was to be inscribed among the tribe or fraternity, of him who adopted him. Having thus left his own tribe, he was not at liberty to return to it again, till he had begotten a child in his new relation ; but, even in that case, he was not obliged to return to his former parentage, though he had this privilege, if he chose. For the enrolment of adoptions, a particular time was appointed ; viz. the fes- tival S^af.^Aia. Sir William Jones, in his introduction to the speeches of Isaeus, mentions the following express laws of Athens. "Adopted sons shall not devise the property accjuired by adoption; but, if they leave legiti- mate sons, they may return to their natural family. If they do not return, the estates shall go to the heirs oi the persons who adopted them. The adopted sons, (if there be any,) and the after-born sons to the person who adopted him, shall be coheirs of the estate ; but no adoption by a man, who has legitimate sons then born, shall be valid." On this the learned commentator ob- serves, that, both at Athens and at Rome, an adopted son acquired all the rights, both sacred and civil, and succeeded to all the advantages and burdens, of the new family, into which he was introduced ; and was consid- ered in every light as a son, by nature born in lawful wedlock. But " an adopted son could not himself adopt another ; he must either have a legitimate son, or the estate, received by adoption, must return to the adopting father's heirs ; for there could not be two adopted sons at the same time." To prevent rash and inconsiderate adoptions, the Lacedaemonians had a law, tliat they should be transacted, or at least confirmed, in the pre- sence of their kings. Among the Romans, there were two forms of adop- tion : the one before the prsetor, called adoptatio ; the other, during the commonwealth, at an assembly of the people, and afterwards by a rescript of the emperor, called adrogaiio. In the firstrthe natural father address- ADO ADO 143 cd the praetor, flcclaring, that he emancipated hir, son, resit;ntii all aulhoiky over him, and eoiiscnted that he should be taken into' the adopter's faiiidy. The other mode was practised when tlie party to be adopted was already free. The person adopted changed all his for- mer names, and assumed the prenamc, name, and sur- name, of the adoptuig father. In the reign of Nero, the senate ordained, that fraudulent adoptions should be of no avail, cither to qualify men for honours, or to en- title them to the whole of any inheritance. By the law of Mahomet, adoption is no impediment to marriage. Among the Turks, the ceremony is per- formed by obliging the adoptive person to pass between the shirt and skin of the adopter. For this reason, to adopt is expressed by the phrase, to draw another tlironi^'h my shirt ; and an adopted son is called by \.h.er\\,.-lkictogli ; i. e. The son of another life ; because he was not begot- ten in this. Something like this is observable among the Hebrews : Elijah adopts the prophet Elisha ; first by putting his mantle upon him, and then l)y letting it fall, when he was ascending in the chariot of tire. (1 King-s, xix. 19. 2. Ki)igs, ii. 15.) Du Cange supposes, that the adoption of Godfrey of Bouillon, by the emperor Alex- ius Comnenus, who named him the champion of the em- pire, and dignified his homage with the filial name and rights of adoption, was of this kind. Among the Greeks and Armenians, as well as the Turks, this ceremony is frequently performed merely by the adopting person exchanging girdles with him who is adopted, when he succeeds to all the rights and honours of a son. To prevent their estates from falling into the grand seignor's treasury, when they are not likely to have any children of their own, they also some- times choose a child of either sex, amongst the mean- est people, and carry the child and its parents before the cadi, and there declare, that they receive it for their heir. ' The parents, at the same time renounce all future claim to it ; a writing is drawn and witnessed ; and a child thus adopted cannot be disinherited. Besides these ceremonies, many of which have a stri- king resemblance to each other, various other methods of adoption have taken place, and are denonlinated accor- ding to the forms that were employed among Gothic and military nations.

In this manner, the king of the Hcruli was adopted by Theodoric ; Athalaric, by the emperor Jus- tinian ; and Cosroes, by the emperor Justin. The ob- ligation here laid on the adopted son was, to protect and defend the father from injuries, affronts, Sec. To this Selden ascribe s the origin of dubbing knights. {Tit. of Hon. p. 865.)

The forms, times, objects, and places of adoration, are different in different coun- itics, according. to the customs and religions which pre- vail in them. The origin of this practice is to be found in the universal and just opinion, that the seinimentsof the heart ought to be expressed by articulate language, and external actions The teini, l)eing derived irom ihc Latin words ail and orare, signifies, to apply the hand to the mouth, i. e. to kiss the hand. This practice, wiiich seems to be of Persian origin, {Herodot. Clio. Cap. 131.) being one of the great marks of respect and submission in eastern countries, was easily and naturally transfer- red to idolatrous worship. Dc La Valle gives the loUowing account of this mode of adoration in India. " At Surat is seen a great and fair tree, held in great veneration. On high, there hangs a bell, which those that come to make their fool- ish devotions, first of all ring out, as if thereby to call the idol to hear them ; then they fall to their adoration, which is commonly to extend both hands downwards, as much as possible, being joined together in a praying pos- ture ; which lifting up again, by little and little, theu bring to their mouths as if to kiss them ; and, lastly, ex- tend them so joined together, as high as they can over their heads, which gesticulation is used only to idols and sacred things. This ceremony being performed, some make their prayers standing ; others prostrate themselves, with their whole bodies grovelling on the earth, and then rise again ; others only touch the ground with the head and forehead, and perform other like acts of hvuTiility." Travel.-, in Lidia, p. 20. In the East, it is still considered as a mark of the highest respect, to take off the shoes, and approach barefooted to pay adorations. (See L.rod. iii. 5. and Josh. V. 15.) The Egyptians were particularly attentive to this practice ; and the Mahometans observe it, when- ever they enter their mosques. When Mr Wilkins wish- ed to enter the inner hsiTl of the college of Seeks at Patna, he was told that it was a place of worship, open to him and all men ; but that it was necessary for him to take oft" his shoes, (Asiat. l\'es. vol. i. p. 289) ; and Ives, in his Travels, (p. 75.) says, that "at the doors of an Indian Pagoda, are seen as many slippers and sandals, as there are hats hanging up in our churches." The Romans, when practising adoration, having their head covered, applied their hand to their lips, with the fore finger resting on the thumb, which was erect ; and thus bowing the head, turned themselves from left to right. This kiss was called osculum labratum ; for or- dinarily they were afraid to touch the images of their gods with their profane lips. But Saturn and Hercules were adored with the head uncovered ; whence the wor- ship of the last was called institutum peregrinum, and Titus Grxcanius, as being different from the usual method of the Romans. Sometimes also standing was the attitude of adoration : sometimes the body was inclined forward, and the eyes fixed on the earth ; sometimes kneeling, wliich was a very common practice ; and sometimes complete prostra- tion on the ground. Sitting, with the under parts of the thighs resting on the heels, seems to have been custom- ary among the Egyptians ; almost all the figures of wor- shippers discovered in their sacred buildings, being represented in this posture. The Persians, and other eastern nations, turn their faces towards the sun, or to the east. Adoration was also performed, by placing crowns, gar- lands, &;c. on the statues and images of the gods ; sitting down by them, or praying to them in whispers, to be fa- vourable, favcas mihi. 144 ADO ADR These vitcb v.xre practised at sacrifices, offering up vows, consecnumg temples, dedicatiuji spoils, passijig by sacred places, and at the sight ol tne statues and ima- ges ol the gods.

And the sick, in particular, did so, in the temple of TEsculapius, {Plant. Circ. i. 1, 61. J Idois were also freqvicntiy placed at the gates oi cities, to re- ceive the homage ol those who passed. The Jewisii forms of adoration, were standing, bow- ing, kneeling, and prostration. The Christians adop- ting the Grecian, raliier than the Koman mode, always adore with llieir heads uncovered. The ancient Chris- tians ordinarily knell in private ; but stood on the Lord's day. Tiiis is still the com..ion practice among Presby- terians, and in America ; but the Lutheran churches usually adopt the torm of kneeling ui public worship. The Roman catholics, at the adoration of the cross on Good-1'riday, walk barefooted, though this custom is not observed by them in Protestant countries. Herodo- tus relates, that when the Persians met, if one of them ■was but a little inferior to the otlier, they kissed each other ; but if greatly ulterior, he prostrated hhnself, and adored or worshipped his superior. The manner of adoring their prince, introduced by Cyrus, consisted in bending their knee, falling on their face at his feet, striking the earth with their forehead, and kissing the ground. The kings of Persia, indeed, never admitted any one into their presence, gave audience, or conferred favours, without exacting this ceremony. No instance of servility can be stronger than the following mentioned by d'Herbclot. A conquered prince threw himself on the ground, and kissed the hoof-prints of his victo- rious enemy's horse, reciting the following verses in Persian : " The mark that the foot of your horse has left upon the dust, serves me now for a crown. " The ring, which I wear as the badge of my slavery, is become my richest ornament. "While I have the happiness to kiss the dust of your feet, I shall think that fortune favours me with her ten- derest caresses, and her sweetest kisses." The history of Ilaman and Mordecai, shows that simi- lar reverence was paid to the favourites of princes : and according to Philostratus, in the time of ApoUonius, a golden statue of the king was exposed to all who en- tered Babylon ; and none but those who adored it were admitted within the gates. This homage, however, Conon refused to pay to Artaxerxcs, and Callisthenes to Alexander the Great, thinking it unlawful and impious. The Roman and Grecian emperors were adored, by bowuig or kneeling at their feet, laying hold of their purple robe, presently withdrawing the hand, and ap- plying it to the lips. This, however, was an honour to which none but persons of some rank or dignity were admitted. The common mode of adoration consisted in falling on the groud, and kissing the feet of the em- peror ; and Dioclesian, who is supposed to have bor- rowed it from Persian servitude, had gems fastened to his shoes, that these honours might be more willingly paid to him. This practice was continued till the last age of the Greek monarchy. Exceptuig only on Sun- days, when it was waved, from a motive of religious pride, this humiliating reverence was exacted from all v\ho ciuered the royal presence, from the princes u.- vested with the diadem and purple, and from the am- bassadors who represented their independent sove- reigns, the caliphs of Asia, Egypt, or Spain, the kings of France and Italy, and the Latin emperors of ancient Rome. {Gibbun, chap. liii. vol. x. p. 124. 8vo.

It seems to have been borrowed from the imperial court, and was early received by the Romish prelates, who, to prevent the charge of impiety, fastened crucifixes to their slippers, that the adoration intended for the pope might seem to be transferred to Christ. Even princes sometimes of- fered this incense to papal vanity ; and Gregory XIII. actually claimed it as a duty. In the ancient church, the same ceremony is said to have been practised to all bishops ; the people kissing their feet, and saluting thera thus ; Ts-^on-Kva tn, I adore thee, {il) ADOWA, the capital of Tigre, a province in Abys sinia, situated on the declivity of a hill, on the west side of a small plain, which is surrounded by mountains, lis name, signifying Jiass, or pansage, is exactly expres- sive of its situation ; for whoever wishes to go from Gondar to the Red Sea, must pass by the flat ground on which Adowa is situated below the river Ribieraini.

He is known in history as one of the seven warriors, who led their forces against Thebes, in support of Polynices, who had been excluded from his share in the government of that city by his brother Eteocles. Adrasius was the only one of the allied chiefs who survived this expedition; and he is said ta have escaped only by the swiftness of his horse. This war is rendered famous by the Thebaid of Statius. About ten years after, the sons of these seven leaders renewed the war with the Thebans, in order to avenge the death of their fathers. They were called Epigoni, or descendants, and their exploits form the subject of Wilkie's Epigoniad. Adrastus v/as also engaged in this war ; in which Thebes was taken, and his son jEgialeus slain.

He was !)orn at Rome on the 24lh of January, in the 76ti\ year of the Cnrislian era, and about y29 years after the building of llic city. He was proclaimed emperor by tlie legions in the year, 1 17, A. U. C 870 ; or, according to Crevier, A. U. C. 868 ; and he died on Oic lOih of July, A. D. 138. Adrian was left an orplian when only ten years of age, and put under the guardianship of Trajan, in conjunc- tion with Caeiius Tatianus, a Ronvan knight. He made a rapid progress in tlie learning of his time ; and seems to have imbibed, at an early period, that love of know- ledge which afterwards distinguished him ; being so re- markable for his acquaintance with the Greek language, that he procured for himself the appellation of " the young Grecian." He served as a tribune of the army in Lower Mcesia ; and had the honour of informing Tra- jan, that Nerva had adopted him as his successor, and of congratulating liim upon that joyful event. He was the first also who carried the intelligence of Nerva's death to the same illustrious person; and having com- niuiiicated the tidings, he immediately saluted him as emperor. But as Trajan disliked him on account of the fickleness of his temper, and the preference which he seemed to give to literature, when compared with arms, Adrian attempted to engage the empress Plotiua in his interests, and courted her with such assiduous atten- tion, that, by her means, (ff £f«7.

While some of these notes were sounding, I applied an obstacle indifferently to any point, which divided the string into such aliquot parts as would pro- duce these notes, and the TEolian note was not interrupt- ed ; but if I placed it in any other part, the tone was instantly extinguished. This evidently shows, that the entire string is, in fact, resolved into sucii parts, as, from the preceding chain of reasoning, we should have been induced to prescribe tor it. Obs. 3. I appplied an obstacle slightly against the string, so as that its distance from the extremity should be an aliquot part of the whole ; and the iEolian note was that which would be produced by such an aliquot part ; thus we may, in general, predetermine what note the harp shall sound. But this effect will not invariably take place ; because, though the obstacle may determine the string to resolve itself into such aliquot parts rather than any others, yet the blast may be too strong or too weak to admit of such a part vibrating with suflhcicnt strength to produce a sound ; however, if any note be produced in this case, it must either be that of this very aliquot part, or of some of its aliquot divisions ; for the obstacle must necessarily determine one of the intersec- tions of the equal indentures. Obs. 4. When the blast rises or falls, we find the tone also gradually rise or fall ; because, as the blast ri- ses, it grows too strong to admit of the vibrations of the longer aliquot parts ; tlie vibrations of the short aliquot parts therefore will predominate, and will gradually shorten, as the blast rises in strength. But, in cases of sudden variations in the strengtli of the blast, there will be also sudden transitions in the tones. Obs. 5. We sometimes hear a chord consisting of two or three jEolian notes ; because, the blast, which is of such a degree of strength as to admit of the vibrations of certain aliquot parts, may also admit of the vibrations of other parts, if they be not very different in length; for their vibrations will be performed in times not very different. But if the lengdi of these parts, and conse- quently their times of vibration, be very different, the blast that admits of the vibration of the one will prevent that of the other. Accordingly, in looking over the fore- going note, we find, that the chords consist of those notes which -are produced by such different aliquot parts as are least unequal : thus, one chord consists of C and E, which notes arc produced by one-sixth and one-se- venth of the string. Another chord consists of F and A, which are produced by one-fourth and one-fifth of the string. Another consists of A, C, and E, which notes are produced by one-fifth, one-sixth, and one-seventh parts of the string. It is also worthy of observation, that, in long strings, we never hear the original note and its octave at the same time ; because, though they are the next aliquot parts, yet their difference is so great, that the blast which admits of the vibration of one of them will ob- struct and prevent the other. It is only in the higher divisions of the string that the chords are heard at all ; and the slacker the note, the more frequent are the chords, for the reasons assigned above ; namely, because the different aliquot parts, in such cases approach near- er to equality. Obs. 6. jEolian tones arc often heard, which are not produced by any exact sub-multiple of the string ; but such notes are very transitory, and immediately vary their pitch, gradually falling or rising to the notes next below or above them, which arc produced by exact ali- quot parts of the whole string. This arises from the transition of the divisions of the siring from one number to another; for, during this transition, the parts of the string, whose vibrations produce the note, are gradually lengthening or shortening. Tims, suppose the iEolian tone was produced by one-third of a string, and that the breeze so varies as to cause this tone to fall into the oc- tave of the original note, the points of quiescence will gradually run along the strings, and by so doing will produce a tone gradually flattening, until it terminates in the octave to the whole string. Discords are also often heard from the unison strings of this instrument : the cause of this is also evident from the manner in which the notes are generated ; for thi aliquot parts of a string contain in themselves an infi- nite variety of discords." A very simple iEolian harp has been recently invent- ed by Mr Crosthwaite. It has no sounding-box, but consists merely of a number of strings, extended be- tween two thin deal-boards.

(/;) jEON, a word employed by the Platonists to denote any perfection, virtue, or attribute, and hence they repre- sented the Deity as an assemblage of all posible aeons. This term was afterwards applied to the Supreme Be- ing himself, and also to the angels. The aeons seem to have been borrowed from the eastern philosophy, which was partly adopted by the Gnostics and Valentinians, who corrupted the purity of the Christian faith by the base mixture of a wild philosophy, (tu) jERA, a fixed point of time, distinguished by some re- markable event, to which both preceding and future events are referred. See Chronology, (to) AERIAL Perspective, the relative colours of visible objects, as modified by distance, by accidental varieties of light, and by the intervention of atmosphere. This term is, however, more generally employed, to signify the art of imitating these colours in painting. The laws by which this art is regulated, by no means admit of that precision which accompanies those of lineal per- spective. In the latter of these, which has for its object to determine the apparent form, place, and bulk, of the various parts of his scene, the artist avails himself of in- variable principles, which admit of mathematical demon- stration ; in the practice of the former, he must rely al- most entirely on the delicate and cultivated accuracy of his immediate perceptions. How very far these percep- tions are wide of the truth, till corrected by the closest attention, and by long practice, every artist who has studi- ed to detect the real appearances of nature, will readily admit. Habituated from our earliest years to correct the information of the senses by the knowledge we have previously acquired, it becomes afterwards a difficult ex- ertion to give, even for a moment, our undivided atten- tion to the real sensation communicated by the exter- nal organ, and to prevent that sensation from being mo- dified by the insensible, and almost mechanical sugges- tions of the judgment. It is by means of this habitual process in the economy of our perceptions, that we ascribe the same colour and the same dimensions to any known object, although seen at very different distances; a process which, though absolutely essential to the truth and consistency of our judgments, it is the business of the artjst to counteract and suspend at will. It is by this acquired faculty that he is enabled to look at nature under that aspect which his art demands, and to mark, without any sensible exertion, those delicate and evane- scent varieties of form and colour, which escape the or- dinary observer. It is the most obvious and general fact in aerial per- spective, that objects assume a fainter tone of colour, the farther they arc removed from the eye of the spec- tator. This fact is founded on the imperfect transpa- rency of the atmosphere, and on the divergency of the rays of light reflected from objects of an unpolished sur- face. Among olijecis of this description, we find that the strong opposition of light and shadow which they exhibit when near the eye, is gradually reduced nearer to equality as we recede from them. The shady side becomes lighter; the illuminated part of it becomes less brilliant. In the case of flat polished surfaces, such as that of still walei', which reflect the sun's rays without any sensible divergency, we find that the light loses lit- tle of its force and brilliancy by distance, except when diminished by the imperfect transparency of the me- dium through which it is transmitted. But as to all the nicer distinctions exhibited in the aerial perspective of nature, it is impossible to lay down any rule which ad- mits of general application. Not only the infinite variety of the local colours of objects themselves, but every ac- cidental distribution of light', every transient change in the state of the air, creates new appearances, and forms new relations in the apparent colouring of the different parts of the scene. In some of the most sublime effects observable in nature, we occasionally find the middle ground of a lighter hue than the distance. In order to assist the exertions of the eye, on which the artist, in co- pying nature, must ultimately depend, it may be recom- mended as an useful practice, to hold up against any ob- ject another resembling it in real colour, and thus, by comparing them together, we shall the more readily dis- cover the change produced, even by the distance of a few yards. ((■) AERIAL Acid, a name given by Bergman to carbo- nic acid gas. (w) AERIANS, in ecclesiastical history, a species of Arians, who took their name from Aerius, an Armenian priest of the fourth centur)'. Besides adopting the pe- culiarities of Arianism, they also held other opinions, which they thought of great importance to the interests of pure Christianity. They had the misfortune to dis- approve of prayers and offerings for the dead ; to repro- bate the celebration of Easter, and other rites of the same nature. They zealously maintained too, that there was no scriptural distinction between bishops and presbyters ; and that all ministers of the gospel should be equal in rank and power. This, of course, mightily provoked the hierarchy of the day ; and the poor Aerians soon fell easy victims to mitred bigotry, {n) AERIFORM Fluids, a name given to the different gases. See Chemistry, (to) AEROLITHS, from axf , the air, and AiSos, a stone, a name recently and very improperly given to the mine- ral substances which have fallen from the atmosphere. See Meteoric Stones, (w) 159 AERONAUTICS. Aeronautics, from «?f , the air, and vat/Tixi), the ar/ of navigaii'jn, is the bciciicu of navigaliiiij the uir by moans ©1 balloons. This science, however extravagant it might at lirst appear us an object either of philosophical speculation or probable success, has been prosecuted vyith increasing interest and attention tor a considerable period of time. While the ait of traversing the air was unknown, man- kind, guided by those superstitious notions which ac- company the infancy of knowledge, regarded it as the exclusive privilege of those supernatural agents, who by their power over the elements, were permitted to penetrate uito regions, which nature had prohibited to man. But though such opinions prevailed from periods of the remotest antiquity, they began, even during the darker ages, to yield to more rational conceptions. Ro- ger Bacon was among the first philosophers who sug- gested the possibility of traversing the air by means of mechanical contrivances: He mentions a machine for flying, as in his time certainly known, "not that he him- self had seen it, or was acquainted with any person who had done so, but he knew an ingenious person who had contrived one." It is evident, hov/ever, that he alludes to some method of putting artificial wings in motion. In later times, John W^ilkins, bishop of Chester, an in- genious mechanic, who died in 1672, published a trea- tise Concerning a jVenu WorW, in which he maintains the possibility of reaching the moon, provided he could be conveyed beyond the earth's attraction. He supposes the different strata of the atmosphere to be of different densities; and concludes, that a vessel filled with lighter air, will float on heavier air, just as a ship is buoyed up by the water. In the same work he asserts, that a fly- ing chariot might be constructed on mechanical princi- ples; and in his Mathematical JSIagic, wliich was a sub- sequent publication, after specifying various artificial methods of flying, he gives the preference to the flying chariot, on account both of its superior utility, and the greater probability of its success. Nearly about the same period, Francis Lana, a Jesuit, suggested a method of traversing the air, founded on the same principles as those which are at present adopted. He proposed to provide four hollow spheres of copper, each 20 feet in diameter, and so thin, that on exhausting the included air, they would float in the atmosphere, and be capable of supporting a vessel or any other load. This plan, though founded on strict philosophical prin- ciples, was abandoned on account of its practical defects : Not only was Lana's method of procuring a vacuum im- perfect, but the thickness of the metal being necessarily reduced to ^ of aline, it was found insuflicient to resist the external pressure of the surrounding air. This con- trivance is described in a work, intitled, Prodronw a'e/l' Arte Maestra Brescia, 1670. It has been said, that a basket of wicker work, of se- ven or eight feet diameter, which was constructed at Lisbon, was exhibited in 1736, and upon trial ascended to the height of 200 feet. But we have been able to ob- tain no satisfactory accounts of the experiment. In the year 173 5, there was published at Avignon, by Joseph Galien,a small work, intitled, ^'■L'art de naviguer etans les airs," in which the author asserts, that a bag of cloth or leather, filled with an air lighter than that of the atmosphere, might be employed with perfect security for tiie purpose of aerial voyages. But though Galien was correct in the principle which he assumed, he seems to have been ignorant of the existence of any lighter spe- cies of air, except what is to be found in the higher re- gions ol the atmosphere. In the year 1782, the science of aeronautics was car- ried in France to an unexampled degree of perfection. It was already known, that air was an elastic fluid, pos- sessing the same general properties as other fluids ; and that il a certain bulk of it was displaced by another body of the same bulk, but of less specific gravity, that body would float. From these data, Stephen and Joseph Montgolficr, two brothers, who were proprietors of a paper manufactory at Annonai, were first led to the con- struction of balloons. Observing the natural tendency of smoke and clouds to ascend in the air, they conceived it practicable to confine an artificial cloud, which would also rise and carry along with it the inclosing substance. The first experiment which they made was at Avignon. They prepared a bag of silk, of the form of a parallelo- piped, containing about 40 feet when inflated. In the lower part was formed an aperture, and when burning paper was applied to it, the bag expanded by the rare- faction of the internal air, rose rapidly, and struck the ceiling of the apartment where the experiment was made. In the next experiment, it ascended 70 feet in the open air. Encouraged by this success, the inventors enlarged the scale of their experiments. A bag containing 650 cubic feet of air, rose 600 feet high. A spherical bal- loon, 35 feet in diameter, was next prepared. It con- tained 23,000 feet of air, and was capable of raising a weight of 500 poimds. It was filled with rarefied air, produced by the combustion of chopped straw and wool placed below the aperture. On the 5th June, 1783, when the experiment was made, a crowd of spectators assem- bled to witness this new and interesting invention, and the result justified their most sanguine expectations. The bag ascended 6000 feet into the atmosphere, and fell at the distance of 7655 feet from the place of ascent. Stephen Montgolfier arriving soon afterwards in Pa- ris, the Royal Academy of Sciences, with a laudable libe- rality, invited him to repeat the experiment at their ex- pense. He accordingly constructed a large balloon of an elliptical form, 72 feet in height, and 41 in diameter. It weighed lOC'O pounds, and was supcrljly ornamented. In a preliminary experiment, it raised eight men from the ground; and on the I2th September, 1783, in pre- sence of the members of the Academy, it bore up a load of between 400 and 500 pounds, but was accidentally damaged by a violent blast of wind. A new balloon, of nearly the same dimensions, was therefore constructed ; three living animals in a wicker basket were attached to it, and it ascended in presence of the royal family. An accident similar to the former unfortunately affected the success of this experiment, and the balloon did not rise above 1440 feet. It fell at the distance of 10,200 feet from the place of ascent, without any injury to the ani- mals. Another balloon was prepared, 74 feet high and 48 in diameter, with which M. Pilatre de Rozier offered to make an aerial voyage. To the lower part of it was 160 AEBONAUTICS. subpcadcd a gallery of wickcv work, ihrec feet broad, wilti a balustrade of the same height. The Ulterior di- ameter was about 16 feet, and the aperture of the bal- loon iieai'Iy the same. Below the aperture was an iron grate, hung by chains from the sidesof the balloon, which the aeronaut could easily supply with fuel. M. Pilatre de Rozier, after making several successful trials with this balloon, while restrained by ropes, resolved to ven- ture on an aerial voyage. On the 21st November, he look liis place on one side of the gallery, and the marquis d'Arlandes occupied the other side, to preserve an equi- librium. The whole, when thus loaded, weighed up- wards of 1600 pounds. The balloon rose majestically before the wondering spectators, above 3000 feet in the air; and in 25 minutes descended above five miles from the place of its outset.* In the beginning of the year 1784, a balloon of prodi- g'ious size was constructed at Lyons, being nearly 130 feet high, above 105 in diameter, and containing 540,000 cubic feet of rarefied air. This immense machine re- quired more than 50 men to retain it when inflated ; and it was capable of raising from the ground six persons, and 3200 pounds of ballast. On the 19th January, 1784, after being filled in only 17 minutes, it ascended up- wards of 3200 feet, with seven aeronauts in the gallery. But a rent of 50 feet, in consequence of the badness of the materials, brought it to the ground, in 15 minutes from the beginning of its ascent ; the aeronauts, how- ever, suffered no injury from the accident. In February 1784, an aerial voyage, made from Milan by three Italian gentlemen, in a balloon 68 feet in di- ameter, was attended with a degree of success which contributed to inspire still gi-eater confidence in this sin- gular mode of conveyance. Such were the leading experiments made with bal- loons filled with rarefied air; but the science was des- tined to undergo still greater improvements. An aeriform fluid, now denominated hydrogen gas, had been long known ; but till the year 1766, its pro- perties had not been ascertained. Mr Henry Cavendish then instituted a series of experiments for that purpose, and found, among other properties, that it was only one-seventh of the weight of common atmospherical air. It immediately occurred to philosophers, that if a quan- tity of hydrogen gas could be confined within any light substance, that substance would rise in the atmosphere. Dr Black, about 1767 or 1768, suggested, that the allan- tois of a calf filled with this gaseous substance, would vise from the earth; but it was not till the year 1782, that hydrogen gas was actually employed to support bodies floating in the atmosphere. Mr Tiberius Cavallo raised soap bubbles in the air, by filling them with this gas ; but he failed in his application of the gas to every other substance. Since balloons filled with rarefied air had ascended, it was evident that the substitution of hydrogen gas, whose specific gravity was much less, would insure * About the termination of the year 1783, the late in- genious Dr Rittenhouse, in conjunction with Mr Hop- kinson, instituted a number of experiments with bal- loons at Philadelphia, in America. They connected to- gether several of them, of a small size, and thus enabled a man to ascend to the height of about 100 feet. Through timidity, however, he would not allow of a higher eleva- tion.

Two brothers, accordingly, Messrs Roberts, and Mr Charles, professor of experimental phi- losophy, constructed a balloon at Paris, of a spherical form, and 13 feet in diameter. It was made of silk; and in order to render it impermeable to the inflamma- ble air, which they procured from sulpiiuric acid and iron filings, they varnished it with a solution ot elastic gum. After experiencing much difficulty in filling it, they found its ascensive power to be 35 pounds. On the 27th August, 1783, it was tried, and ascended up- wards of 3000 feet, in the short space of two minutes. After traversing a space of 1 5 miles, it was brought to the ground by a rupture, which was probably effected in the higher regions of the air, by the expansion of the gas. In November 1783, a balloon, 10 feet diame- ter, constriirled by count Zambeccari, ascended from London, and after two hours and a half, came down at the distance of 48 miles from the place of ascent. Animated by these successful results, Mr Charles and the two Messrs Roberts resolved upon attempting an aerial voyage, in a balloon filled with inflammable air. One was accordingly prepared by the Messrs Roberts, of varnished silk, of a spherical form, 27 feet in diame- ter, which had a car suspended to it, for the accommo- dation of two adventurers. To prevent any danger from the expansion of the air, the balloon was furnished with a valve, formed in such a manner as to permit the free discharge of gas when occasion required. On the 1 7th December, 1783, Mr Charles, and one of the Roberts, having previously ascertained the direction of tlie wind, by launching a small balloon, ascended from Paris to the height of 600 feet, and after a voyage of an hour and three quarters, descended at a distance of 27 miles from the place of their departure. The balloon being then rendered 130 pounds lighter by j\Ir Roberts leaving his station, Mr Charles set out alone in the car, and in 20 minutes found himself elevated 9000 feet above the surface of the earth. At this immense height, all ter- restrial objects had totally disappeared from his view. The thermometer stood at 47° when he left the earth; but in the space often minutes it fell to 21°. The efi'ects which so rapid a change of situation produced upon his body, were violent in the extreme. He was benumbed with cold, and felt a severe pain in his right ear and jaw. The balloon passed through different currents of air ; and in the higher regions, tlie expansion of the gas was so powerful, that Mr Charles was obliged to allow part of it to escape, in order to prevent the burst- ing of the balloon. After having risen to the height of 10,500 feet, he came down about a league from the place of ascent. The balloon, including the two aero- nauts, thermometer, barometer, and ballast, weighed 640 pounds ; and tlie inflammable gas was found, on calculation, to be about 5^ times lighter than common air. M. Jean Pierre Blanchard, an ingenious French gen- tleman, who had been projecting some mechanical con- trivances for flying, constructed a balloon, 27 feet in diameter, and being accompanied by a Benedictine friar, he ascended from Pans on the 2d March, 1784. After rising 15 feet, the balloon was precipitated upon the ground with a violent shock, and the friar, apprehen- sive of his safety, was induced to abandon his seat. Mr Blanchard then ascended alone to the height of 9600 feet. He met with different currents of air. He felt extreme cold, and being oppressed with drowsiness, he descended after a voyage of an hour and a quarter. In AERONAUTICS. 101 fti-der to diKct his caui'se, he employed on this occa- sion an apparatus, consisting of a rudder and two wia:^s, which were attached to the car, but found that it cxeil- ed little or no influence over the balloon, cither in this or subsequent voyages. In April 1784, Messrs Morveau and Bertrand adopt- ed a similar expedient, \vhich they found to operate very sensibly on the direction of their balloon. They rose about 13,000 feet high, where they enjoyed one of the most sublime and magnificent prospects that the ima- gination could conceive. The mass of clouds that float- ed hi silent disorder through the regions below, pre- sented the appearance of a serene and boundless ocean, while a beautiful parhelion of concentric circles, that began to form as the sun was going down, heightened the grandeur of the scene. In the month of June fol- lowing, M. de Morveau undertook another voyage, which, as well as the former, commenced at Dijon. His bal- loon was 25 feet in diameter, and made of varnished taffeta. A similar device for regulating the course of the bal- loon was resorted to by the Messrs Roberts, who had t)efore ascended together. Their former balloon was c-onverted into an oblong spheroid, 46 feet by 27, the longer axis being parallel to the horizon ; and the car, which was 17 feet long, had five wings or oars disposed around it, for the purpose of steering. The INIessrs Roberts, and M. Collin Hullin, upon entering the car, threw out 24 pounds of ballast, which produced a gen- tle ascent. The current of air between the altitudes of 600 and 4200 feet was uniform. On arriving at' the height of 14,000 feet, they encountered some stormy clouds, which they endeavoured to avoid, by alternately ascerding and descending. In three hours from their ascent, they heard two peals of thunder, when the ther- mometer fell from 77° to 59°. Finding themselves soon afterwards becalmed, they had recourse to their oars, by the exertion of which, their balloon, in 35 minutes, described an elliptical segment, whose shortest diame- ter \7as 6000 feet. After travelling 150 miles, in the space of six hours and a half, they descended in safety. The Messrs Rolierts, accompanied by the late duke of Orleans, and a fourth person, ascended in July 1784, in a balloon different in its structure from any that had hitherto been tried. On all fomier occasions, aeronauts had found the method of effecting a descent by a dis- charge of gas, attended with inconvenience ; and to obviate this difficulty, the Messrs Roberts had suspend- ed a small balloon within the large one. The interior balloon was to be filled with conmion air, by means of bellows attached to it, whenever they wished to descend ; it being justly supposed, that the addition of common ail- would increase the wciglit, as its diminution would, on the other hand, lighten the balloon. This expedient, however, though promising in theory, did not answer in practice. In the space of three minutes, they rose to a height where not an object was to be seen but the clouds that surrounded them. The balloon, no longer obeying their management, was tossed, with the most violent agitation, as if from one whirlwiiid to another. The cords, by which the interior balloon was suspended, being cut, it fell down in such a position as completely to close up the aperture which communicated between the large balloon and the car. A sudden gust of wind next drove them beyond the region of the storm ; but the expansion of the inflammable air increasing, they dreaded tlie bursting of the balloon ; and being unable Vol. I. Part T.. to remove the small one, which obstructed the aperture, they continued to ascend. It was then rent in two places ; and notwithstaniling the imminent danger to which they were exposed, from the rapidity of its de- scent, they all landed unhurt. Though several experiments on the ascensive powfcr of balloons had been made in England, (luring the course of the year after their discovery, the first aerial voyage, which was undertaken by Vincent Lunardi, aii Italian, did not take place till September 1784. His balloon was 53 feet in diameter, and shaped like a pear. It was made of oiled silk, with alternate stripes ol blue and red, having the car suspended from a hoop belovir the balloon, by 45 cords. In January 1785, an aerial voyage across the English Channel, the most adventurous that had hitherto been projected, was made by Mr Blanchard and Dr Jeffries. They left Dover castle on the 7th of thai month, at on'e o'clock. The Imlloon for some lime rising slowly and majestically in the air, they passed over several ships, and enjoyed a grand prospect of the numerous objects below them. They soon, however, found themselves beginning to descend, and were under the necessity oT throwing out half their ballast, when they were about one-third of the way from Dover. When half way across the channel, the ballon again descended; upon which they threw out all their ballast, and also some books, which they had carried along wilh them. At half an hour after two, tliey were obliged to throw away every part of the apparatus that could possibly be want- ed ; but still the balloon was descending, in spite of all their efforts. The anchors and cords were then thrown out ; and, as the last expedient in their power, the aeronauts stripped themselves of their own clothes. This, to their infinite satisfaction, changed the sinking tendency of the balloon ; and reaching the French coast, they passed over the high lands between cape Blanc and Calais, and landed in the forest of Guienncs. Encouraged by the successful issue of this enter- prise, M. Pilatre de Rozier, and M. Romaine, ascended from Boulogne, in July, with the intention of crossing the English Channel. To insure the power of ascent and descent at pleasure, they availed themselves of the combined effect of two balloons ; one filled with inflam- mable air, about 37 feet in diameter, and another with ra- refied air, whose ascensive power was about 60 pounds. The latter was suspended belov.- the other, at such a dis- tance as precluded all apprehension of danger from the fire which was under it. They had not, however, been long in the air, before the spectators perceived the baU loon swelling very quickly ; and when they had attain- ed the height of nearly three quarters of a mile, the whole apparatus was observed to be in flames. This disaster was attended with fatal consequences to the unfortunate adventurers. They were precipitated from their car, and dashed to pieces upon the ground. See jIn Excursion from Paris to Foiiiituijibkau. London, 1786. In September following, Mr Baldwin ascended from Chester. When scarcely a mile and a half high, the earth appeared to be seven miles distant ; the whole face of the country seemed a perfect plain, and the build- ings had no apparent height. After passing through various currents of air, he saw the clouds of a pure white colour, moving in detached fleeces. Above these he observed a vast mass of dense thunder clouds, at unequal distances, resembling in colour the smoke of K 162 AERONAUTICS. ordnance. In this voyage, he remarked, as had been done before, that tlic progress of the balloon was much aflected in passing over water. At the greatest altitude, his respiration was free, and he felt no perceptible in- crease of cold. In June 1786, M. Testu ascended from Paris with a balloon, 28 feet in diameter, on the motion of which he was able to produce a very sensible effect by the manoeuv- ring of wings. It was filled only | with gas ; but, at 2900 feet high, became quite lull, by the expansion which it underwent in the rarer atmosphere. Dreading the bursting of the balloon, should he continue to as- cend higher, he applied himself vigorously to the man- oeuvring of the wings ; and after much difficulty, and severe labour, descended, in the plain of Montmorency, to take in ballast. Here he procured some stones with- out leaving the car. A crowd of people, impelled by curiosity to see him, forced their way through a field of corn, which was so considerably damaged, that the pro- prietor seized on the aeronaut for indenuiification. Twen- ty persons held a cord which was fixed to the car, and conveyed it along, the balloon floating about six yards from the ground. But when they were triumphantly entering the village with their prisoner, he suddenly cut the cord by which the car was restrained, and made his escape into the air, to the utter amazement of his cap- tors. After descending a second time, he rose again and passed through clovtds which emitted vivid flashes of lightning, accompanied by loud peals of thunder. The sun was then setting ; and shortly afterwards, he encoun- tered a storm. His balloon was tossed about among clouds, some of them snowy, and others charged with rain. An iron point, fixed to his car, emitted a stream of light from the positive electricity of the atmosphere ; and, when negative^ it exhibited a luminous spot. His flag, bearing the arms of France in gold, sparkled with fire during the darkness of night, while the thunder rolled, and the lightning flashed around him. The storm lasted for three hours ; and during all that time the aero- naut durst not allow any of the gas to escape, lest its communication with the electric matter should have pro- duced an explosion of the balloon. The tempest at length abated, and was succeeded by a perfect calm. From a sublime elevation he beheld the sun rising ; and after being twelve hours in the air, descended near the village of Campremi, 25 leagues from Paris. His clothes and balloon were impregnated with a strong sulphureous smell ; and his flag had been rent by the lightning. In June 1794, during the late war, M. Coutef ascen- ded in the Entrcfirenant balloon, to reconnoitre the hos- tile armies at the battle of Flcurus, accompanied by a general and an adjutant. They rose twice to the height of 440 j-ards, and remained four hours in the air ; and it is said, that the signals which they communicated to General Jourdan decided the fate of the engagement. The enemy fired at the aeronauts, and one ball passed so near, that they thought at first it had struck the car. In June 1802, M. Garnerin, together with captain Sowdcn, ascended from Ranelagh Gardens during a storm of wind. They soon rose above the clouds, and lost sight of the earth. In their descent, they had to pass through thick black clouds, where the balloon suf- ftrcd violent agitations ; and in three quarters of an hour from their departure, they landed sixty miles from Ran- elagh, though not without sustaining much injuiy from sudden gusts of wind. On the 4th July, M. Garnerin, attended by Mr Lock- er, ascended again during a heavy gale. On this oc- casion he readied a height of 7800 feet in fifteen mi- nutes ; the balloon came down nine miles distant from the place of ascent, and struck the ground with such violence as to rebound 1 50 or 200 feet into the air. A discovery which enabled men to visit regions of the creation, which Nature had appropriated to another part of the animal system, and to overcome difficulties which had hitherto defied the most daring speculations of phi- losophical enterprise, excited sensations of the deepest wonder and interest over all Europe, and called fonh a degree of activity and zeal in the improvement of aero- nautic machines, which had seldom been devoted to the other sciences. The limits of our work, however, will not allow us to describe all the aerial voyages that have been undertaken, and the various peculiarities by which they were characterized ; but we shall indulgt; our readers with an account of the most remarkable. The fatal accidents to which the aeronaut might .some- times be exposed, induced philosophers to devise expe- dients for diminishing the danger. So early as the year 1783, M. le Normand made the experiment of leaping from the height of a first stoiy with a parachute, 30 in- ches in diameter, in his hand ; and so much did it break the force of the fall, that he was hardly sensible of any shock upon reaching the ground. He thence calculated, that a parachute, 14 feet in diameter, attached to a mao, might protect him against all possible injury, though fall- ing from the regions of the clouds. During M. Blanch- ard's ascent from Strasburg, 26th August, 1787, he dropped a dog, connected with a parachute, from the height of 6000 feet. A whirlwind, however, interrupted its descent, and bore it above the clouds. M. Blanchard afterwards met the parachute, when the dog, recognis- ing his master, began to bark ; and just as M. Blanch- ard was going to seize it, another whirlwind suddenly carried it beyond his reach. Having passed vertically over Zell, he terminated his voyage ; — the parachute, still waving in the air, came down twelve minutes after- wards. He also sent up several small balloons, contain- ing parachutes, to which dogs were attached ; and con- structed them in such a manner as to burst on arriving at a very great height. When the balloons were burst, the parachutes were necessarily set at liberty, and conveyed the animals in perfect security to the ground. In a dar- ing experiment, however, which he had the courage to make on himself, he was less successful ; for on hazard- ing a descent by a parachute at Basle, he unfortunately broke his leg. Notwithstanding the discouraging termination of M. Blanchard's attempt, M. Garnerin, by the success which followed his experiments with the parachute, gave phi- losophers absolute confidence in its efficacy. The sixth occasion on which he tried it, was in his ascent from Paris on the 21st October, 1797. Between the car and the balloon was placed the parachute, half expanded, and foiTning a kind of tent or canopy over his head. The weather was favourable, and the balloon made a rapid ascent. When nearly 2000 feet high, as M. Garnerin conjectured, he separated the parachute from the bal- loon, while he himself was attached to the parachute. Its descent, as it gradually unfolded, was slow and ver- tical ; it afterwards began to oscillate, and acquire a ro- tatory motion, and soon conducted the aeronaut in safety to the ground. In September 1802, he repeated the same experiment at London. M. Garnerin, as had been pre- vioftsly announced, ascended at six o'clock of a clear 5e- AERONAUTICS. 165 i-cnc afternoon. In eight miilutes he rose 8000 feet, when he cut a\ra5' the parachute from tlic balloon, and descended along with it. During Iho first thirty seconds of descent, it proceeded with astonishing rapidity ; but, undergoing a sudden expansion, it assumed a more gen- tle and equable motion. Soon, however, it began to oscillate, like a pendulum, with such a degree of vio- lence, as to render the aeronaut apprehensive for his own safety. His fears were soon dissipated, by its be- ginning to move more calmly; and he came to the ground without any hurt. At the moment of separat- ing the parachute, the balloon took an ascending direc- tion; and was found next day 12 miles distant irom the place of departure. In July 1803, M. Garnerin made his Uiirty -third aerial excursion from Petersburgh, accompanied by Madame Garnerin, and his thirty-fifth from Moscow. During the latter, a huntsman, who spied him hovering over a wood, fired at him, which induced him to descend. On the 7th of Octobei', count Zambeccari, Dr Gras- setti, and signer Pascal Andreoli, ascended from Bologna. As the filling of the balloon could not be completed be- fore midnight, the count was desirous of postponing the attempt till the following day; but his inclinations were obliged to yield to the clamour of the populace, who would not permit any delay. The balloon mounted with great velocity ; and in a short time reached an elevation where the count and Dr Grassetti were benumbed by the intense cold, and fell into a deep sleep. About half past two, they began to descend ; and signer Andreoli, who still preserved his senses, observing the waves of the Adriatic dashing against the coast of Romagna, awakened his companions ; and in a few minutes the balloon was precipitated into the sea. The aeronauts, in the utmost consternation, threw out their ballast, and every thing else that could be disposed of ; on which it immediately re-ascended, and passed through clouds where their clothes were covered with hoar frost. At three o'clock it began to descend again, and a violent squall drove it across the Adi'iatic towards the coast of Istria. The car several times touched the waves ; and, during four or five hours, the aeronauts were on the surface of the sea, without any hope of being rescued from the terrors of their perilous situation. But at eight in the morning, at the distance of twenty Italian miles from the harbour of Veruda, in Istria, they were acci- dentally delivered, by a vessel, from the fate that threat- ened them. Soon after this period, several aerial voyages were undertaken for purposes of scientific observation ; among which the ascent of professors Robertson and Sacharoff from Petersburgh, on the 30th June, merits particular notice. Their balloon was 30 feet in diameter, and con- tained 9000 cubic feet of hydrogen gas. The whole apparatus, including ballast, instruments, and the aero- nauts themselves, weighed about 725 pounds. A small balloon previously launched, was first driven from the coast, but on rising higher took its course towards the sea. Nevertheless, the aeronauts embarked a little past seven, P. M., and the balloon ascended slowly. On pass- ing the Neva it sunk ; but by discharging part of their ballast, it again resumed its flight. A telescope had been fitted in the bottom of the car, to view distinctly the objects over which they passed ; and they employ- ed a very light log, consisting of two sheets of paper suspended by a thread, to ascertain the rise and fall of the balloon, of which they found it a more sensible index than the baromete>. In the course of the vovagc, the balloon turned round si veral times slowly ; and during a perfect calm, which prevailed for some time, its mo- tion was imperceptible. The aeronauts filled empty vessels with air at different heights ui the atmosphere. At one time, they proposed to continue theij- voyage al! night ; but, from their ignorance of their actur.1 situation in the sky, and from total want of ballast, they were in- duced to descend. They landed accordingly, before eleven, without the smallest shock, 40 miles from Pe- tersburgh. Professor Robertson ascended again fron» Riga, in the same month, and in his descent threw oui hooked anchors to secure the balloon, instead of trusting; to the uncertain assistance of men at the place of des- cent. He ascended also from Vienna in October. We avoid detailing the voyage wliich professor Robertson, along witli Mr Lhoert, accomplished in 1803: because the phenomena, which are said to have attended that ex- cursion, have not received confirmation from succeeding observations. In August 1804, count Zambeccari, accompanied by sig. Andreoli, made another ascent from Bologna. They set out at ten in the morning ; and at one o'clock, when the aeronauts found themselves above Capo D'Argine, six Italian miles from Bologna, the balloon became in- visible to the spectators. The count having then at- tempted a descent, his anchor caught a tree, when a lamp in the car being overturned, from the oblique posi- tion of the balloon, the spirit of wine, which it contained, took fire. The flames communicated with a vessel con- taining 30 pounds of the same spirit, and as this immedi- ately burst, the fire attacked the clothes of the aero- nauts, which instantly called their whole attention to themselves. The count succeeded in extinguishing the flames which tlireatencd him, and sig. Andreoli having escaped by sliding down the anchor-rope, the balloon was thus lightened about 150 pounds, and with the count alone sprung rapidly into the air, and soon disappeared among the clouds. In this situation of danger and alarm, it was by his great presence of mind and laborious ex- ertions alone, that he was able to extinguish the fire in the car. He was now carried by a strong current to- wards the Adriatic, and could very faintly distinguish the coast of Comachio. The balloon was soon afterwards precipitated into the sea, 25 Italian miles from the coast. The car, which was half-burnt, sunk in the wa- ter: and the count, then holding fast by the ropes of the balloon, was frequently up to the neck. Having fast- ened one of them round his body, he remained in this comfortless aiid hopeless condition, when seven fishing boats came in sight at six in the evening. The crews of four, terrified at the strange appearance of the aero- naut with the balloon floating over him, conceived it to be some large sea-monster, and fled ; but the rest less influenced by fear, than by curiosity, ventured to ap- proach, and rescued the count, after he had been four hours in the water. The fishermen, preparing to take in the balloon, inadvertently cut the ropes below, on which it rose suddenly into the air, and was carried to- wards the Turkish coast. On the 27th August, 1804, Messrs Gay Lussac, and Biot, ascended at Paris, from the garden of the Conser- vatoire des Arts, carrying along with them a variety of apparatus for the purposes of observation. The clouds, through which they passed, resembled light fogs, and excited a slight sensation of humidity. After surmount- ing them, they appeared bluish, the same as when X 2 104 AERONAUTICS. viewed from llic caj'lli. As they rose higher, the hy- Ljiometcr indicalcd increasing dryness, and the balloon assumed a slow rotatory motion, but not always in the same direction. They ascended upwards of 13,000 feet, and came down 15 leagues from Paris. On the sixth of September, about ten in the morning, M. Gay Lussac set out on a voyage by himself from the same place. The atmosphere below was lull of vapour, but without clouds, and when the balloon was above 1900 feet high, he perceived a light vapour floating ilirough the \ov. er regions, which allowed him an indis- tinct view of distant objects. At eleven minutes past three, M. Gay Lussac found himself 22,965 feet above Palis, and was astonished to see the clouds still above fiim. In his former ascent none of the clouds were higher than 5iOO feet, and the sky was as deeply co- loured as Prussian blue ; but in this instance there were no clouds below him, and the sky was dull and full of vapours. He now reached the immense height of 23,100 feet above the earth. In thirty-four minutes after the period of ascending, he landed without injury six leagues north-west of Rouen. On the 7th April, 1806, M. Mosment, an experienced aeronaut, undertook an aerial voyage from Lisle. He ascended at noon, waving a flag decorated with the im- perial eagle of France, amid the shouts of the assembled spectators. The coniniencemcnt of his career was so rajjic^, as to bear him in a very short time beyond the vision of the crowd. During his ascent, he dropped an animal attached tea parachute, which came safely to the ^^ound. About one o'clock, something was observed slowly descending through the atmosphere, which pro- ved on its fall to be the flag which M. Mosment had tarried along with him. Very soon afterwards, a mur- mur circulated through the crowd, and the body of the unfortunate aeronaut was discovered in one of the fosses of llie city lifeless, and covered with blood. The balloon reached the ground on the same day, at the distance of 25 leagues from Lisle ; the car containing nothing ex- cept an luiloaded pistol, a liule bread, and a piece of flesh. M. Garnerin ascribes this melancholy disaster to the extreme shallowness of the car, and the too great distance between the cords which attached it to the bal- loon ; and is of opinion, that M. Mosment, when leaning over the car to drop the animal, had lost his balance, and was precipitated to the earth. Of all the vovages which the history of aeronautics presents to our notice, the nocturnal aerial excursions of M. Garnerin must be ranked among the most en- terprising and adventurcus. At eleven o'clock in the evening of the 4th August, 1807, he asei^nded from Ti- voli, at Palis, under the Russian flag, as a token of the peace that subsisted between France and Russia. His balloon was illuminated by twenty lamps ; and to obvi- ate all danger of communication between these and the hydrogen gas, which it might be necessary to discharge in the course of the voyage, the nearest of the lamps was 14 feet distant from the balloon, and conductors were provided to carry the gas away in an opposite direction. After his ascent, rockets, which had been let off at Tivo- !i, seemed to him scarcely to rise above the earth, and Paris, with all its lamps, appeared a plain studded with luminous spots. In forty minutes, he found himself at an elevation of 1 5,200 feet, when, in consequence of the dilatation of the balloon, he was under the necessity of discharging part of the inflammable air. About twelve o'clock, when 3&00 feet from the ejrth, he heard the barking of dogs ; about two, he saw several meteors fly- ing around him, but none of them so near as to create apprehension. At half past three, he beheld the sun emerging in brilliant majesty, above an ocean of clouds, and tiie air being thereby expanded, the balloon soon rose 15,000 feet above the earth, where he felt the cold exceedingly intense. In seven hours and a half from his departure, M. Garnerin descended near Loges, 43 leagues distant from Paris. The same intrepid aeronaut undertook a second noc- turnal voyage, on the 21sl September, 1807, in thft course of which he was exposed to the most imminent danger. M. Garnerin prognosticating an approaching storm, irom the state of the atmosphere, relused to hv accompanied by M. de Chassenton, who earnestly re- quested it. He ascended therefore alone from Tivolij at ten o'clock, and was carried up with unexampled ra- pidity to an immense height above the clouds. The balloon was there dilated to an alarming degree, and M. Garnerin, having been prevented by the turbulence of the mob, before his ascent, from regulating those parts of the apparatus which were meant to conduct the gas away from the lamps on its escape, was totally inca- pable of managing the balloon. He had no alternative left, therefore, but with one hand to make an opening, two feet in diameter, through which the inflammable air was discharged in great quantities ; and, with the other, to extmguish as many of the lamps as he could possibly reach. The aeronaut was now without a regulating valve ; and the balloon, subject to every caprice of the whirlwind, was tossed about from current to current. When the storm impelled him downwards, he was for- ced to throw out his ballast, to restore the ascending tendency ; and at last, every resource being exhausted, no expedient was left him to provide against future exi- gencies. In this forlorn condition, the balloon rose through thick clouds, and afterwards sunk ; and the car, having struck against the ground, with a violent im- pulse rebounded from it to a considerable altitude. The fury of the storm dashed him against the mountains; and, after manv rude agitations and severe shocks, he was reduced to a state (^f temporary insensibility. On recovering from his perilous situation, he reached Mont Tonnerre in a storm of thunder. A very short time after his anchor hooked in a tref ; and, in seven hours and a half, after a voyage which had nearly proved fatal to him, he landed at the distance of 3o0 miles from Paris. Although these aerial voyages, which wt have thus briefly narrated, are the most conspicuous in the histo- ry of the science, yet many others have been underta- ken, both in Britain and on tlie continent, which the ingenuity, and the enterprising spirit of the adventurers, the circumstances of unforeseen intricacy and danger they had to encounter ; and, above all, the scenes of tem- pestuous grandeur through which they passed, must ren- der subjects of lively interest to the curious : and we regret that, solicitous as we arc to gratify the taste of such a class of readers, our limits prevent us from de- tailing the more unimportant and less remarkable voyages that have taken place. Use of Balloons. The advantages hitherto derived from aerial naviga- tion have by no means proved adequate to the expecta- tions excited by the novelty and promising aspect of the science. This failure in their utility may, in a great degree, be ^scribed to the art of steering balloons being AERONALTICS. 1G5 biill undiscovered : It must also be lemcmbercd, that by tar tilt greatest iiiiuibcr of aerial voya^^es which have been allLinpted, were undertaken purely for the i^raiifi- cation of curiosity ; and tliat comparatively few of tlicni have been conducted witii llie precaution of philosophi- cal inquiry, or lor the purpose of scientific discovery. In choosing the figures ot the balloons, likewise, the admiration of the multitude seems more frequently to have been consulted than the fair and equable movement of the machine, or the safety of the aeronaut. A bal- loon, constructed in imitation of the human figure, clothed in a flame-coloured robe ; or of a Pegasus transporting through the clouds a richly-accoutred war- rior, could not fail to fascinate the senses of a crowd. The French, indeed, who are ever ready to apply the discoveries of science to objects of practical utility, during the first war after the overthrow of the monarchy, instituted an academy for the express purpose of im- proving the state of aeronautics. This institution was established at the Royal Lodge of Mendon, near Paris, and was conducted with the utmost secrecy. There was a corps of aeronauts, consisting of fifty youths, trained to the service ; and a spherical balloon, 32 feet in diameter, was kept constantly prepared for exerci- sing, and fastened to the great terrace of the lodge, in the open air. In favourable weather it was loosened ; and with the car, which contained the colonel of the corps and a pupil, attached to it, it was allowed to as- cend from 160 to 240 yards ; but it was still restrained by a cord fastened from below. A balloon, recently filled, required twenty people to hold it ; and, even after the lapse of two months, notwithstanding the loss of gas that had taken place, it could support two persons and ballast in the air. Balloons were here prepared tor the service of the dilTerent armies ; the Kntrrtirenant for the army of the North, the Celeste for that of the Sam- bre and Meuse, and the Hercule and Intrepidc for the army of the Rhine and Moselle. The management of the institution was committed to men of eminent repu- tation ; the celebrated chemist, Guyton Morveau, ren- dered it essential advantages ; and M. Conte was chief superintendent. It was reported, some years ago, to have been in a very flourishing condition ; but it is now said to be entirely abandoned. M. Lomet has been very lately employed, by the French government, in making experiments, to ascertain whether balloons miglit not be advantageously enii)loyed in the survey of countries, for the construction of geographical plans. The irre- gular motion of the balloon in ascending presented many obstacles to the sliccess of his experiments ; but, nevertheless, M. Lomet conceives that they might Ije used with great benefit for that purpose. It has like- wise been proposed to make an aeronautic telegraph, by which signals might be communicated through the medium of a machine attached to the balloon. The Abbe Bertholon has used balloons in electrical experi- ments. Those which he sent up, had long slender wires proceeding from them, witli the end terminating in a glass-rod, or other insulating substance ; and from the wires he procured the electric spark. The respiration is always affected by ascending liigh into the atmosphere, probably in conseqi^ence of the rarefaction of the air; the pulsation is increased, the head is sometimes swelled, and the throat parched. The temperature, according to the most authentic observa- tions, decreases in proportion to the height : whence, jn great altitudes, a numbness'is felt, and the propen- sity to sleep so irresistibly strong, as in some cases to have actually overpowered the aeronauts. The mag- netic power was tound, by M. Gay Lussac, to prevail at the height of 12,372 feet, the same as on the surface of the earth. At the same time, other aeronauts have thought it very sensilily diminished ; though we are in- clined to suppose, that this opinion may liav^ possibly arisen from their inattention to the disturbing causes. From an experiment made by the chemist already men- tioned, electricity seemed to increase in proportion to the height ; which, he observes, is agreeable to the theory of M. Volta and Saussure. SacharolV ascertained, that a bell had the same intensity of sound when the barometer fell to 23 inches, as it had at the surface of the earth ; and, when it had sunk to 22 inches, the words spoken downwards from a speaking-trumpet, were re- verberated to the ears of the aeronauts, after a lapse of 10 seconds before their return. Some time after the invention of balloons, an experiment was made to ascer- tain whether the sound of thunder, rolling among the clouds, was only an echo travelling troni cloud to cloud, or a succession of distinct explosions. A balloon, five feet in diameter, was prepared by Mr Boullon of Bir- mingham, which was furnished with inflammable mate- rials to communicate the fire. When sent into the air, accordingly, an explosion took place ; but a shout, at that moment, from the crowd assembled on the occasiori, rendered it impossible to distinguish any succeeding explosions. M. Testu, who, in one of his ascents, con- tinued for a long time amidst a thunder storm, says, that the hollow sound was very loud but short ; that it was preceded and followed by a hissing or tearing, resem- bling the noise of something rending asunder. The composition of the air, at the height of 21,849 feet, has been found to be the same as at the surface of the earth. Various currents prevail at different alti- tudes, and some of them in directions diametrically op- posite to each other. Storms, too, are frequently local ; and, when the aeronaut surmounts the region of their influence, he is safe. The velocity with which a bal- loon is transported in the fury of a tempest, if not so well authenticated, would almost stagger our belief ; in- stances have occurred where it has not been less than 70 or 80 miles an hour. The structure of the clouds has, in appearance, been compared by some to a plain of snow ; and by others, to a sea of cotton. Some, again, have compared those charged with electricity to the smoke of ordnance. Clouds consisting of hail or snow are frequently met with, in such abundance, that these substances may be gathered in handfuls from the car. Others consist of mist or rain, in which the aeronaut, who is every moment exposed to a change of tempera- ture, is copiously drenched. Notwithstanding all the changes experienced in an aerial voyage, the gas con- tained in the balloon always preserves a much -higher degree of heat than that of the surrounding atmosphere ; a fact that has not as yet been satisfactorily accounted for. Birds, or other v/ingcd animals, when allowed to escape at a great height, either fall down with precipi- tation, on finding the quality of the fluid different from what they have been accustomed to, or they descend obliquely in their flight, describing long curves similar to those of birds of prey. Construction of Balloons, In the formation of balloons, three things are to be at- tended to : the strncture of the balloon containins the 166 AEUOXAUTICS. air which produces its ascent ; that of the parachulc ; and of the car or boat, which receives the aeronaut. Ballooiiiiare either spherical or elliptical ; the spherical ibnn, however, has been almost universally adopted, probably because a sphere admits the greatest capacity under the smallest surface. Balloons filled with rare- fied air, have usually been made of common linen, soaked in a solution of alum to obviate the risk, of fire, and varnished to prevent the escape of the air. It is ot advantage to have them of a considerable size, because a smaller quantity of fire will produce a greater propor- tional rarefaction, and it is besides attended with less danger. It has been thought that the most eligible figure for a balloon with rarefied air, is an inverted cone, or a truncated pyramid, as it would allow the heated air, which has both a tendency to ascend and to expand, to occupy the wide part above, while the lower part would contain the colder air. Experiments, however, have proved, that the ascensive power depends by no means on the figure of the balloon. Mr Cavallo recom- mends, that the opening of a rarefied air balloon above the fire, should be one-third of the diameter of the bal- loon itself, if the size exceeds 50 feet ; and that it should project from the balloon by a cylindrical neck. The gallery for the aeronauts is placed on the outside of this neck, and the fire-place for rarefying the air within it. Above the edge of the gallery, holes are cut for introducing fuel to the fire. Small balloons after this method, may be made of paper, with a wire roimd the bottom. Two or three cross wires are fixed in the centre to support a cup, containing cotton and spirits of wine, the flame of which rarefies the air, and produces the ascent. We shall now proceed to consider the con- struction of balloons filled with inflammable air, whose superior advantages deserve a more detailed and atten- tive description. The substance uniformly used for the envelope of in- flammable air, is silk lustring, which, from its close texture, strength, and lightness, is peculiarly suitable for the purpose. The price, however, of this material is so extremely high in Great Britain, as to render the con- struction of a balloon even of a middling size very ex- pensive. Hence a late judicious writer on this subject suggests the expedient of substituting strong cambric muslin, rinsed in drying oil, previously to the junction of the separate pieces. In calculating the weight and quantity of cloth requisite for constructing a balloon of a given diameter, we have only to multiply the square of the diameter by 3.1416, and the product will be an area of the surface of the sphere, or the quantity of cloth ne- cessary for its formation. Thus, if the balloon be 12 fget diameter, we have 12x12x3.1416=452 square feet nearly, or 50 square yards for the quantity of cloth. The weight of this quantity of cloth will be found by multi- plying the number of square yards by the weight of one- yard of the cloth. The solid contents of the balloon may be found by multiplying the cube of its diameter by 0.5236. When the capacity of the balloon is determined, it will not be difficult to ascertain its power of ascent. A cubic foot of atmospherical air weighs about 1 .2 oz. ; whence a quantity of air, equal in bulk to the solid con- tents of a spherical balloon, 35 feet in diameter, weighs 26,950 ounces, or about 1684 pounds. Suppose the in- flammal)le gas in the balloon is six times lighter than common air, then the weight of it is 280 pounds, which occupy the same space as the atmospheric air displaced ; to this add 428 pounds, the weight of the bag or envelope, and the whole makes 708 pounds : deducting this num- ber from 1 684, the weight ol common air displaced, there remain 'J76 poimds, as the ascensive power, or specific levity of the balloon. This method of computation will lead to the proper results, whatever be tlic dimensions of the balloon, or the specific levity of the gas. Thus, a a balloon 30 feet in diameter requires 314 yards of cloth, and its ascensive power will be 581 pounds. One, 20 feet in diameter, requires 140 yards, and its power is 122 pounds. In sewing together the corresponding edges of the separate pieces of the envelope, one is left half an inch broader than the other, and is turned over in a subse- quent row of stitches. This double seam is put be- tween two pieces of brown paper, and pressed with a fire-iron, heated just enough to soften the drying oil. One or two tubes of the same material as the balloon, are used for introducing the gas, and these are tied up whenever it is filled. A balloon of 30 feet diameter re- quires two tubes of six inches. The whole external sur- face is covered with a coat of varnish. The following composition, prescribed by Cavallo, is the best for this purpose. " Boil a pint of linseed-oil with two ounces of sugar-of-lead, and three of litharge ; and when they are dissolved, put a pound of birdlime, and half a pint of the drying oil, into an iron or copper vessel, and allow it to boil gently over a slow charcoal fire, till the birdlime ceases to crackle, which may require about half an hour or three quarters. Then pour two pints and a half more of the drying oil upon it, and let it boil about an hour longer, taking care to stir it frequently. It will be found to be sufficiently boiled, when, by rubbing a little of it between two knives, the varnish, on their separation, draws into threads. After it is removed from the fire, and nearly cold, add about an equal quantity of spirit of turpentine." When the varnish is to be used, it should be luke-warm, and the balloon stretched out. It dries in the space of 24 hours. Another varnish has been made from a pre- paration of caoutchouc, or Indian rubber. This is done by dissolving that substance, cut into very small pieces, in five times its weight of ethereal spirit of turpentine, which is effected by keeping them for some days to- gether ; then boil an ounce of this solution a few minutes in eight ounces of drying linseed oil ; and having strained it, apply it while warm to the balloon. As the balloon would be in danger of bursting, by the degree of expansion which the included air undergoes in the higher regions of the atmosphere, a valve is em- ployed for allowing the air to e^icape, when the balloon is too much distended. It has generally been placed at the top of the balloon, though the equator of the balloon, has been recommended as tlie best position for the valve. The car, whose size and figure are quite arbitrary, is made of wicker, covered with leather, and well varnished. It is attached to the balloon by cords, proceeding from a net-work, which covers the upper half of the balloon. These cords are collected about two feet below the balloon, in the circumference of a circle, from which other cords are distributed down to the edges of the car. The meshes of the net-wcrk are smaller above, because it is there that the greatest strength is required. la some instances, it is connected by means of a hoop, made usually of wood or cane, and encircling the balloon. The car is represented in Plate III. Fig. 3., and also in Plate IV. Fig. 1. at CD. The exact dimensions which a parachute ought to AERONALTICS 167 have, in order to be an instrument of perfect security and confidence, have not yet been ascertained. Tlie para- chute, by which M. Garnerin descended at Paris in 1797, was 25 teet in diameter, and was made of cloth ; and that by which he descended at London in 1802, is said to have been a large umbrella, consisting of 32 gores of canvas, 23 feet in diameter, and without ribs and handle. At the top there was a round piece of wood, 10 inches in diameter, having a hole in the centre, which was fast- ened to the canvas by 32 short pieces of tape. About four feet and a half from the top of the canvas, a wooden hoop, eight feet wide, was put on and tied by a string from each scam Several ropes, about 3U feet long, pro- ceeding from the edge of the parachute, terminated in a common joining. From this point there issued sjiort- er ropes, to whose extremities was fastened a circular basket, in which W. Garnerin himself was stationed. The parachute and basket were immediately disunited from the balloon, by the cutting of a cord which com- municated with the net-work, and in falling downwards, the parachute naturally expanded, by the resistance of the air. Several improvcn-.ents on the parachute have been suggested ; viz. by constructing it of varnished cambric muslin, or liglU linen, covered externally with a netting firmly fixed to it ; by making the diame- ter, when expanded, not more than 20 feet, and forming but a small segment of a sphere ; by having a central aperture in the segment, fully three feet in diameter, to allow the escape of the air as it descends ; and by fur- nishing this with a shutter on a hinge, which the aero- naut might close or open, according to circumstances, by means of a cord connecting the shutter with the bas- ket. The parachute, when open, is represented in Plate IV. figure 2; and figure 3 represents it when shut. Since it would be a work of infinite labour to collect hydrogen gas as it exists in its original and natural state, the method of procuring it from the chemical ac- tion of bodies is always resorted to as the most conve- nient and productive. It may sometimes be obtained in such purity, as to be twelve times lighter than common air, but in general its specific levity is only five or six times greater. It is usually procured from a solution of iron or zinc in sulphuric acid. The iron best adapt- ed for the purpose, is the turnings produced by the bo- ring of cannon ; but when this cannot be obtained, chips of iron should be preferred to filings. It is of impor- tance to attend to the purity of the metal ; for rust produces hydrocarbonate, a gas which is specifically heavier than atmospherical air. Grease also is injuri- ous, because it resists the action of the acid. The sul- phuric acid must be diluted with five or six times its weight of water. Iron yields about 1700 times its own bulk of gas ; therefore, 4| ounces of iron, with the same weight of sulphuric acid, and 22^ of water, will produce a cubic foot of inflammable air ; and of zinc, 6 ounces, with the same quantity of acid, and 30 ounces of water, will produce a cubic foot of air. The gas is collected into a number of casks, which are disposed round a large cask or cooler ; the cooler contains water mixed with unslacked lime, and receives the gas from the sur- rounding casks through tin tubes, which connect them with each other; and the gas, purified from any carbo- nic acid gas, which may have incorporated w ith it be- fore it passed through the water, is conveyed by a silken tube from the cooler into the balloon. The smaller casks in which the solution is carried on, ought to be lined with tin. M. Gamer in, in 1803, used 35 casks, every 12 of which communicated with a cooler, and three tubes from the three coolers cjnveyed the gas into a large tube, which was joined to the balloon. Profes- sors Robertson and Sacharofl' had 25 vessels communica- ting with a cooler, into each of which they put 120 poimds of iron filings, (chiefly from cast-iron,) along with 600 pounds of water, and I 20 pounds of sulphuric acid pour- ed over it. The filling of the balloon occupied five hours. M. Blanchaid filled a balloon 21 feet in diame- ter, from only foin- casks, each holding 120 gallons. Lu- nardi, a celebrated aeronaut, reducing the apparatus to still greater simplicity, employed oidy two casks, from which the gas was transmitted into the balloon without passing through water ; and in the short space of half an hour, he filled the balloon in which he ascended from Edinburgh and Glasgow ; it was of a pear-shape, 23 feet in diameter, and 30 in height. M. Blanc hard used 1000 pounds of iron, and 1250 of sulphuric acid, for producing the gas to fill a balloon of 2 1 feet. Lunardi, on the occa- sion we have just now mentioned, employed 2000 pounds of each, and 12,000 of water. The latest writer on this subject computes, that this quantity should suffice for a balloon of 30 feet in diameter, which is 14,137 in capaci- ty. The balloon of 53 feet, in which Lunardi first as- cended in England, and one that ascended from Nantz about the same time, were filled from zinc instead of iron. Making allovtance for the expansion of the gas during the ascent, the balloon is never filled above three fourths. There is also a method of procuring hydrogen gas, by passing water over metals, or through tubes pre- viously heated to redness. Although there is a danger of the metal running to a slag before any considerable quantity of gas is obtained, the aeronautic institution at Mendon, erected an apparatus, consisting of a series of red-hot cylinders, from v/hich they filled their balloon, 32 feet in diameter, in the space of eight hours. This method is found sufficiently productive, and is more eco- nomical than the former. In filling balloons, great care should be taken that they be fixed in such a manner as to prevent them from, escaping prematurely mto the air. Instances have hap- pened, in which a disregard of this precaution has proved fatal to persons who were holding the balloon by ropes ; the balloon, on acquiring a sufficient ascensive power, suddenly rose into the air, before those who were at- tempting to restrain it could extricate themselves from their hold. The exercising balloon at Mendon had aa ascensive power of 800 pounds, which is equal to the strength of 20 people, and it was retained by means of a capstan. We shall conclude this subject by observing, that sails and oars, which have both received the proof of experi- ment, have been found of little or no advantage in guid- ing balloons. Wings or oars have indeed m some rare instances produced an impression on the balloon's course which was barely sensible, and have therefore received no sanction from general use. The total inability of the aeronaut to impress on the balloon a determinate direc- tion, is the greatest defect in the science of aeronautics. Exfilanation of the Figures. Plate III. Fig. 1.

A tin tube T is in- serted in the bottom of each tub, si.K or seven inches in diameter, to which the silken tubes conducting the gas to the balloon are fastened. The casks N,N are surrounded with several other casks, containing the materials producing the gas. From the top of each of these a tin tube introduces the gas into the central casks, from which it passes into the bal- loon.

The strings which surround the balloon are fixed to the hoop AB, to which the boat CD is suspended; and after the balloon is about three quarters full of the gas, the silken tubes are taken from the tin ones T,T, the lateral ropes are slipped off', and the aeronaut is abandoned to the mer- cy of the clement.

Empedoclcs thought, that aether was first separated, next fire, and then earlh ; and that, this being compressed by violent circumagitation, water was made to boil out of it, and the exhalation of the water lastly formed air. -Per rara foramina terrs Parlibus eiumpens primus se sustulit sether Signifer, et multos secum levis abstulit ignes.

The delusion has become contagious, and il IS high time to resist the progress of such crude opinions. Are the phantoms ol certain chemical ex- perimentalists at all more specious or seductive than the dreams of tlicir predecessors, tjie ancient cosaiologists ? On some other occasion, we propose to resume the dis- cussion ; meanwhile we shall conclude with an extract from professsor Leslie's celebrated work on Heat ; — " It is a remarltable and instructive fact, in the history of philosophy, that impulsion should have been at one period the only force that was admitted. The motion of a falling stone was certainly not less familiar to the senses than that of a stone that was thrown : but, in the latter case, the contact of the hand was observed to pre- cede the flight of the projectile, and this circumstance seemed to fill up tlie void, and satisfy the imagination. Gravitation sounded like an occult quality ; it was neces- sary to assign some mechanical cause, and if there were invisible impulses to account for the weight of a body, might not that office be performed by some subtile invi- sible agent ? Such was the sway of metaphysical pre- judice, that even Newton, forgetting his usual caution, suffered himself to be borne along. In an evil hour, he threw out those hasty conjectures concerning aetlier, which have since proved so alluring to superficial think- ers, and which have, in a very sensible degree, impeded the progress of genuine science. So far from resolving weight or pressure into impulse, we have seen, that the very reverse takes place ; and that impulse itself is only a modification of pressure. This statement has already some distinguished adherents, and must, in time, become the received opinion. Science has experienced nmch obstruction from the mysterious notions long tnlertained concerning causation."— P. 135, 136.

He was accounted a man of excellent understanding, and great acuteness, skilled in logic, as well as acquainted with other branches of science. Because he disputed with subtility concerning the nature of God, his enemies branded him with the name oi atheist. He was severe- ly persecuted by Conslantius, and died, not long after, at Constantinople. («) J^TNA. Called by the people in its neighbourhood Monte Gibcl- l(j, is situated on the eastern side of Sicily, in a district which the superstitious fears of the inhabitants have de- nominated Vat de Denione. Various conjectures have been formed respecting the origin of the name jEtna. In the Itineraries it is usually written JEthana. Hence some, who are anxious to de- I'ive every term from a Greek or Hebrew extraction, trace its origin from ccihti, to bum, or the Hebrew Atha- na, a furnace, or darkness. But whatever may be the origin of tlie name, it is certain that this mountain has for many ages attracted the notice of mankind. Its im- mense size and elevation, the beauty and magnificence of the surrounding scenery, and the terrific grandeur of the convulsions and changes to which it is subject, have afforded matter of description both to the poet and his- torian. Here, according to ancient mythology, were erected the forges of the Cyclops, where, under the di- rection of Vulcan, they prepared the thunder-bolts of Jupiter. Here was raised a temple to Vulcan himself, where, as in that of Vesta, the fire never ceased to burn ; and here the giant Enceladus was condemned by Jupiter to expiate his impious rebellion, by perpetual imprison- ment. This mountain, when viewed at a distance, presents the appearance of an obtuse truncated cone extended at the base, and terminating in a bifurcated vertex, i. e. in two eminences at a considerable distance from each other. Upon approaching nearer, the traveller is sur- prised and astonished at the wild, grotesque appearance of the whole mountain ; while he is delighted, at the same time, by the pleasing variety exhibited on particu- lar parts of its surface. Over the whole of the immense declivity of jEtna, but especially in the lower region, he beholds innumerable eminences, or small conical hills, gently rising from its surface, covered with rich verdure and beautiful trees, and adorned with to'wns, villages, scattered hamlets, and monasteries. As his eye ascends, he discovers an immense forest of oaks and pines, sur- rounding the mountain on every side, and forming a zone of beautiful green round its middle. Next appears the hoary head of the mountain itself, boldly projecting into the clouds, and covered with eternal snow. These general characters, so distinctly impressed upon the different parts of its surface, have induced travellers to divide jEtna into three regions, viz. // Jie- gione Culta., the fertile region ; // Reglone Sylvosa, the woody region ; and // Regioiie Deserta, the barren region. Nor are these regions less distinguished by their temperature, than by their external appearance. The traveller, faint and oppressed by the sultry heat of the Regione Picdmontese, escapes with delight, we arc told, into the shade of the woods, where the air is cool and refreshing ; but upon emerging from the forests, the temperature rapidly declines ; and to all the dangers and difficulties attending his journey to the summit, must be added, the inconvenience arising from the pierc- ing coldness of the air, and the chilling blasts from the south, to which these higher regions are constantly ex- posed. Hence, some have been led to distinguish those distinct portions of the surface of iEtna, by the names of Torrid, Temperate, and Frigid Zones. In presenting to our readers an account of whatever may deserve farther notice in the external appearance of jEtna, we shall adopt the common division, and begin with stating the particulars related by travellers respect- ing the lower region, or Regione Cidta. In ascending Mount jEtna, it is usual to begin the journey on the south side, near the city of Catania. From this place to the mouth of the great crater, the distance is supposed to be nearly 10 leagues, or 30 miles. Of this ascent, about 15 miles are allotted for the breadth of the first zone, or Regione Culta The circumference of this region, according to Recupero, is 174 ^TNA. 183 miles ; and its surface, by the calculation of Buffon, exceeds 220 square leagues. It is bounded by tlie sea to the south and soulh-easi, and on all Us other sides by the rivers Scnietus and Alcantara. The circumstance tliat generally attracts the attention of the traveller, in passing through this region, is the remarkable inequality of its suriace, occatiioned by tlie immense number and variety of conical hills which rise around him on every side. They are generally about two or three miles in circuit, and from 30u to 400 feet m height. Were the external appearance of these nills (each of which has a cup or small crater) and tneir prox- imity to the great gult, not sufficient to demonstrate their volcanic origin, we are happily iunushcd with a direct experiment in the case of the loniuition of one of them, viz. Monte Rosso, which must remove every doubt respecting this point. In the year 1669, this hill was seen to rse in the midst ol a plain, and to uiscnarge from its vertex a dreadful torrent ol lava, which ilowed as far as the sea, and formed a kind of promontory. The uncommon fertjliiy of the soil of this region, the richness of the pasture grounds, and the luxuriance of the vines and other fruit-trees, have, from the earliest times, afforded matter of panegyric to the traveller and historian. On this subject, Strabo, Fazello, and all who have visited jEtna, unite their testimony, and agree at the same time in ascribing this superior fertility to the decomposition of the lava. This rich scenery is some- times beautifully diversified, by the lava appearing above the soil, in the form of craggy euiinences. Even where the lava is not uncovered, the soil in some places is so shallow, that the roots of trees, unable to penetrate the hard rock, extend their fibres horizontally, and are seen creeping along the surface. It must be peculiarly in- teresting to a traveller in this region, to reflect that he is now treading on the I'uins of extinguished volcanoes, and to behold cheerful cottages and thriving towns situ- ated in those very hollows whence the destructive fire formerly issued. No fewer than 77 cities, towns, and vil- lages, are said to be scattered over the sides of iEtna ; and the whole population is calculated to be 100,000 persons. As those who have visited .(Etna have taken nearly the same route, they have in general selected the same sta- tions for halting. In the first region, two resting places are particularly noticed, viz. J^icoloai, and St J^icco/o dell' Arena. Nicolosi was formerly a convent belonging to the Be- nedictine friars of Catania. It is now a place of enter- tainment for travellers. Here a solitary brother resides, to take care of the house, and superintend the cultiva- tion of the neighbouring fields. According to Brydone, this station is twelve miles up the mountain, and, by Houcl's calculation, 2496 feet above the level of the sea. The air here is remarkably pure ; but the progress of vegetation is less rapid than in the plain below ; for, as Brydone informs us, the corn is often green at Nicolosi, when the harvest is overat Catania. From Nicolosi, travellers usually make a short excur- sion to Monte Hosso, or the Red Mountain, so called from the red colour which appears on some parts of its surface. The origin of this mountain, as we fomierly observed, is sufficiently ascertained. The approach to it is through a deep bed of black sand, which completely envelops the base of the mountain, and is about two miles in breadth. This sand is the sad remains of the dreadful £ruption of 1669, which gave birth to this hill, and buried in ruins the flourishing vineyards and riclr pastures in its neighbourhood, to the extent of 15 miles. It is even said, that some of the finer particles of this sand reached the opposite coast of Calabria. Autliors disagree respecting the size of this hill. Boreili i» of opinion, that its circumierence at the base docs not ex- ceed two miles, anu its perpendicuiar height 150 paces ; whereas sir W. Hamilton allows one mile lor the lieignt*. and three miles for the circuit. It has a number of mouths or craters, all of which have externally the shape of a funi.el or mutilated cone. M. Houel went down into one of these openings with torches, but could not reach the bottom, behig compelled to return by the severity of the cold. After visiting Monie Rosso, the traveller proceeds oa his journey, and soon arrives at St J\ficcolo deW Arena, an ancient edifice, which formerly belonged to the Bene- dictine friars. Here are seen mnumerable monuments and inscriptions, which record the history of lormer ruins particularly the eruption of 1669. After this dis- astrous event, its original proprietors judged it expe- dient to abandon this station, and sought a more secure residence in the plain below. Few traces of these deso- lations, however, remain to the present day. The black sand thrown out in this memorable eruption, has for many years been converted into vegetable earth, and is now covered with extensive and thrivmg vineyards. In this neighbourhood rises MontejiiUri, another of those hills which diversify and adorn the sides of .£tna. It de- serves notice merely on account of its peculiar shape, and the circumstances which attended its formation- It is of a spherical form, not exceeding 300 feet in height, and about a mile in circuit. It is perfectly regular on every side, and richly overspread with fruits and flowers ; its crater is so completely hollowed out, as to resemble a bowl in its internal structure. But what renders this mountain chiefly remarkable, is, that from the period of the eruption which produced it, we date the ruin of the far-famed territory of Hybla ; which now retains no traces of its former importance, except what we may learn from the name Mel Passi; or from a few verdant hillocks which spot the surface of fields of black and rugged lava. After leaving this hill, nothing occurs worthy of no- tice, till we enter the Regione Syh
