'The American Edition of the ENCTCLOPJEDIA is Dedicated, with the mod grateful refpefl:, by their much obliged fervant, THOMAS DOBSOK S9S115 PREFACE. i HE utility of fcience, and the delight which it affords to the human mind, are ac- knowledged by every man who is not immerfed in the groffeft ignorance. It is to the philofopher that the hufbandnian, the archite<5t, the carpenter, and the feaman. Sec. are indebted for the principles of thofe arts, by which they furnifli us with mod of the accommodations, and with all the elegances, of civilized life ; whilfl the pleafure experienced in the very progrefs of philofophical refearch is fuch, as both reafon and revelation intimate, not obfcurely, will conftitute part of our happinefs in a future flate. Small, however, would be the attainments of any man in fcience, were they confined within the limits of his own refearches. Our knowledge of corporeal nature originates in thofe perceptions which we have by the organs of fenfe ; and which, treafured up in the memory, we can, by the powers of reafon and imagination, varioufly modify, ar- range, and combine, fo as from a number of particular truths to form to ourfelves ge- neral principles. But thefe principles would be few indeed, had each individual no other materials of which to form them than the perceptions furniflied immediately by his own fenfes. It has long been a matter of general regret, that the progrefs of fcience has been flow and laborious ; but it never could have commenced, or could have only commenced, were every man obliged to begin his career from his own fenfiitions, with- out availing himfelf of the difcoveries of others who have travelled over the fame ground before him. To this narrow field, however, philofophical invefligation is not confined. By means of the arts of writing and drawing, the difcoveries of one individual may be made accefilble to another, and the fcience of every age and of every country treafur- ed up for the ufe of ages and countries the moft remote. Hence arifes the utility of what is generally called literature, or the knowledge of the languages, cuftoms, and manners, which have prevailed among the various nations of the earth. Without this knowledge the fcience of the ancients would be locked up from the moderns ; and even the difcoveries of modern nations would be inaccelTible to each other. With all the aid which can be furniflied by one age or nation to another, the la- bours of the philofopher flill prefent themfelves as immenfe and difficult. His objeft comprehends uni\erfal nature, of which nothing can be known but by fenfation and reflcftion ; but the objefts of fenfe arc all individuals, almoft infinite in number, and for ever changing : fo that inflead of a fyflem of fcience, the firft view of the corporeal world would lead us to imagine, that from our mofl diligent refearches nothing could be obtained but a vafl collection of particular truths. Such a collection, whiHt it would burden the memory, could be of little advantage to the arts of life ; for we arc very feldom brought, on different occafions, into circumflances fo perfefHy fimilar, as to require, without the fmallcil variation, the fame coudud. Vol. I. Part I. a But IT PREFACE. But though all the objefts of fenfe, of memory, and of confcioufnefs, are unqueftion- ably individuals diftinft from each other, the contemplative mind of man obferves among them various refemblanccs and analogies. It obftrves, that the fenHition com- municated to the fight by fnow is fimilar to that communicated by milk, paper, chalk, and a thoufand other objefts ; that all external objefts are folid, extended, divifible, and of fome figure ; that the path defcribed by a planet round the fun rcfemblcs that defcribed by a cannon bail over the furface of the earth ; and that many of the aftions of brutes are fimilar to thofe which we are impelled to perform by the internal feelings of defire and averfion. This view of nature, quiefcent and aftive, fuggefted to the philofopher the expedi- ency of ftudyin^ the vaft multitude of objefls which compofe the univcrfe ; not indi- vidually, but in groups clafled together according to their perceived refemblanccs or analogies. He faw that his labour would thus be at once ihortencd and rendered in- finitely more ufeful ; but he likewife faw, or ought to have feen, that it would by no means be taken wholly away. Much cautious attention is requifite to dafs objeifls in human fyftems as they are in faft claffcd in the fyflcm of nature. Analogies are apt to be miftaken for refemblanccs ; a refemblancc in a few particulars for a refemblrince in all ; and events, which have in reality very little in common, to be attributed to the fame or funilar caufes. Thefe miflakes can be avoided only by a painful in- duftion of fafts, by means of experiments accurately made on individual objefts ; and it was but very lately that induction was employed as the inftrument of fcientific re- fearch. In ancient Greece, where philofophy firfl; aflumed a fyftematic form, all the objefts of human thought were ranged under ten CATEGORIES or predicaments; and every thing which could be affirmed or denied of thefe categories was fuppofcd to be com- prehended under five clafles called predicables. Among the Greek phiiofophers, therefore, the ufe of indudion was to afcertain the category to which any particular object belonged; after which, nothing more wa: .jbe done but, by a ihort procefs of fyllogillic rcafoning, to affirm or deny of that objeft whatever could be affirmed or denied of its category. To this ancient arrangement of human knowledge many infuperable objeftions have been urged. But it mull be confefTed, that the arrangements which have been propo- fcd in its flead, by the fages of modern times, have little claim to greater perfeftion. Locke claffed all things under three categories ; substances, modes, and ideas. Hume reduced the number to two ; impressions and ideas. The former of thefe philofopliers admitted of only four predicables, all different from thofe of the ancients ; the latter at firil extended the number to feven, but afterwards reduced it to three ; among which none of the ancient predicables are to be found, and only one of thofe which had been admitted by Locke. These different claffifications of knowledge are the natural confequences of mens at- tempting what the greateft powers of the human intellecft will never be able to accom- plilh. It certainly was the aim of Arillotle, or whoever was the inventor of the categories and the predicables, to delineate the whole region of human knowledge, aftual and poffible ; to point out the limits of every diftrift ; and to affign to every thing which can be the object of human thought its proper place in the vaft arrangement. Such an attempt evinces the ambition of its author : nor has the ambition been much lefs of fome of thofe by whom the raffi arrogance of the Stagyrite has been moll feverely cenfured. Locke fays cxprcfsly, that as the objects of our knowledge are confined to fubllances^ modes, and ideas, fo we can difcover nothing of thefe, but i/?, their identity or diverfity ; 2d, their relation ; T,d, their co-cxiflence or neecffary connexion ; and 4ihy their real exUlence : while Ilurae declares, with fome hefitation indeed, that we caa know nothing but the refemblance, contiguity iu time or place, and canfation of our im- preffions and ideas. These PREFACE. These attempts, as well modern as ancient, to contraft the whole furniture of the human mind into the compafs of a nut-fhell, and to give at once a compleat chart of knowledge, have been ccnfured, not only as prefumptuous, but as the fertile fources of error, by a philofopher whofe writings do honour to this age and nation. " To make a perfect divilion (fays Dr Rcid), a man muft have a perfect com43rchenfion of the whole fubjcift at one view. When our knowledge of the fuhjeft is imperfeft, anv diviGon we can make mufl: be like the firft iketch of a painter, 'to be extended, con- trafted, or mended, as the fubject Ihall be found to require. Yet nothing is mere common, not only among the ancient but even among modem philofophers, than to draw from their incomplete divilions, conclulions which fuppofe them to be perfect. A divlfion is a repolitory which the philofopher frames for holding his ware in con- venient order. The philofopher maintains, that fuch or fuch a thing is not good ware, becaufe there is no place in his ware room that fits it. We are apt to yield tu this argument in philofophy, but it would appear ridiculous in any other traiEc." The truth of thefe obfervations will be controverted by no man who is not an abfo- lute ftranger to the various fyftems, ancient and modem, of what has been called the fir II philofophy. But if every fcientific arrangement of knowledge which has hitherto been propofed be fo very imperfeft, what judgment are we to form of that which is adopted by the compilers of Dictionaries or Encyclopaedias, in which the arts and fcicnces are arranged according to the order of the alphabet, and A, B, C, &c. confidered as the categories ? The author whom we have juH: quoted affirms, that of all methods of arrangement this is the mofl: antiphilofophical ; and if he allude only to fuch Encyclopaedias as arc mere di and apply t External; which is either ing the Or, ^uantitiesoiho. dies — called Mixed Ma- thematics ; wliich, accor- ding to the different fub- je^fts, refolves into r Architecture.

To accomplifli therefore efTciftually wliat Mr Chambers by means of his prefatory fcientifical analyfis attcmpicd in vain, they endea- voured to give a compendious, yet clear and fatisfa^tory, account of the fcveral arts and fciences under their proper denominations, whiift the fubordinate articles in each were likewifc explained under their technical terms. 'I'hcfe fubordinate articles they divided into three kinds ; of which the firft confifls of fuch as, independent of particu- lar fyftems, admit of a full and complete illuftration under their proper names ; the fecond, of fuch as require to be partly difcufTcd under the fyftems to which they belong, and partly under their own denominations ; and the third, of fuch as apper- tain to fyftems of which* all the parts muft be elucidated together. Articles of the firft kind admit of no references ; thofe of the fecond, being only partially explained under their proper denominations, demand references to the fyftems where the illuftrations are completed ; and thofe of the lad are wholly referred to the fyftems of which they arc conftiiucnts. Such has been the arrangement of the Arts and Sciences in every edition of the En- cyclopcedia Britannica ; and it furely falls not under that cenfure which Dr Reid pro- nounced with jullice on many other works bearing a fimilar title. In the fpirit of true philofophy, that great man obferves, that the fame fubjeft may admit, and even require, various divifions, according to the different points of view from which it is contemplated ; and we doubt not but, if he had been afkcd, he would candidly have acknowledged, that the divifions and arrangement of the Encyclopa-dia Britannica are calculated to anfwer every purpofe which can be expeftcd from a gene- ral repofitory of arts, fciences, and mifcellaneous literature. They are fuch as mull give to readers of every delcription the moft eafy accefs to the objects of their purfuit ; for whiKl the philofoplier or fyftematic artift may be fully and regularly informed by turning to the general name of the fcience or art which he willies to explore, the man who has occalion to confult only particular topics will find them illuftrated under the terms by which they are denominated. Contemplated from this point of view, the arrangement of the Encyclopaedia Britannica needs not flirink from a comparifon e\en with that of the Encyclopedic Methodiquc ; for though that voluminous work, confilling of a dictionary of dictionaries, may have the appearance of being more fyilematically arranged ; yet we, who have had occafion to confult it frequently, have never found our oljjeCt: the more readily for having been obliged to travel in quefl: of it through different alphabets. A DICTIONARY, in which the feveral arts and fciences are digerted into diftinct trea- tifes or fyllems, whilft the various detached parts of knowledge are explained in the order of the alphabet, feems indeed to have received the befl form of which fuch a work is fufceptible ; and may certainly be made to anfwer one end, which more philofophical ;irrangcments never can acconiplilli. Under the various letters of the alphabet, it is obvious that the whole circle of the fciences may be completely exhaufted ; and that every difcovery, ancient or recent, may be referred to the particular fyftem which it Vol. I. Part I. b tends Such is that great and general analyfis of know ledge, which has by fome of our correfpondents been recom- mended to us in terms of the highellpraife, and to which elegance and accuracy cannot perhaps be refufed. Its utility, however, as piefixedto a diiSionary of arts and fciences, is not very apparent, l-'rom each word, which in this table is printed in capitals, many branches are made to fpring, whicli in tiie dictionary are all treated as fcparatc articles. Thus from Metiorology wcarc referred, in a fubordinate analyfis, to Air and the At- mosphere: including, ill, The liillory of its contents, VF-vmer, Fire, Vapour, E.v halation, S:c. 2d, Me- teors formed theiein; as Cloud, Rain, Shower, Drop, Snow, Hail, Dew, Damp, &c. Rainbow, Parhelisn, Halo, Thunder, Waterspout, &c. Winds, Monsoon, Hurricane, and the like. As every word printed in capitals, as well in this fubordinate divifion as in llie general table, is the title of an article treated feparatejy in the Cyclopidia, we mull turn backwards and forwards through more than 24 references before we come at the detached topics, wliich we are directed to unite into a fyfleni of MrTtoROLOc y. The number of articles which muft be united in the fime manner to conftitutethe Compiler's fyftem of Metaphv- sics is upwardi of 48 ; and thofe which arc referred to Theology above 300 ! VIU P R E F A C E. fcnJs to confute or to confirm, without havinp; rccourle to the awkward expedient of cmp!o)inL; icveral alpliabets, or the ftill more inconvenient arrangement by whicli the lyllems thcmlelves are broken into fragments. JiuT on this topic it is needlefs to expatiate. The very favourable reception with which the two former editions of the EncyclopxJia Britannica were honoured by the I'ubhc ; the Hill greater encouragement which has been given to the prefent ; and the adoption of the plan by the editors of other repofitories of arts and fciences — l->ear ample teftimony to the excellence of the arrangement. On this fubjefl we exprcfs ourfclves w ith the greater cafe and the greater confidence, that we cannot be accufed of flattering our own vanity, or publifliing our own j^raifes ; for the merit of forming the arrange- ment, as well as of introducing into the work various branches of knowledge, from w hich, as they are not generally to be found in dictionaries, it derives a jull claim to the favour of the Public, belongs not to the Compilers of tlic prefent Edition. After furveying any particular art or fclence, our curiofity is excited to acquire fome knowledge of the private hillory of thofe eminent perfons by whom it was invented, or has been cultivated and improved. To gratify this curiofity, tliofe \\ho formed the plan of the Encyclopaedia Britannica refolved to enrich it with a department not to be found in any prior collection of the fame kind except the French Encyclopedic. Of all the various fpecies of narrative-writing, it is acknou'ledged that none is more worthy of cultivation than biography ; fince none can be more delightful or more ufeful, rone can more certainly enchain the heart by irrefiflible intereft, or more widely dilVufe inRruftion to every divcrfity of condition. Its tendency to illullrate particular paffages in general hiftory, and to diflufe new liglit through fuch arts and fciences as were cultivated by the perfons whofe lives are related, are fafts too obvious to require proof. It exhibits likewife the human characfter in every poflible form and fituation. It not only attends the hero through all the biiftle of public life, but pur- fues him to his moil fequeftered retirements. It ihows how diftingiiilhed characters have been involved in misfortunes and ditlicukics; by what means they were extricat- ed J or with what degree of fortitude and dignity they difcharged the various func- tions, or fullained the viciflitudes, fomctiraes profperous and fometimes adverfe, of a checqucred and a flu(ftuating life. In fuch narratives men of all ranks mufl frel tliem- fclvcs iiitercfled ; for the high and the low, as they have the fame faculties and the fame fenfes, have no lefs fimilitude in their pains and pleafures ; and thereJbre in the page of honeft biography, thofe whom fortune or nature has placed at the grcatefl dif- tance, may mutually afford inflruftion to each other. For thefe reafons it is, that every man of learning and talk has efteemed tlie biographical labours of Plutarch among the mofl valuable and interelting remains of antiquity. '1"h£ lives and cliarafters, therefore, of iuch perfons as have excelled in the arts cither of war or of peace, of fuch as have diftinguilhed themfclves either on the theatre of aftion or in the recefs of contemplation, will be found in the Encyclopa-dia Bri- tannica alphabetically difpofed under their proper names. Many indeed are omitted, for whom the reader will naturally look ; fome becaufe, in the order of the alphabet, we had paffed the initial letters of their names before we had intelligence of their deaths ; others, through the inadvertency, whether excufable or not, of the Editors j fevcral, for a reafon which fhall be afterwards afligned for omifilons of a different kind, and perhaps of greater importance ; and a very few from the contemptuous re- fufal of their friends to anfwer the Editor's letters rcfpeftfully rcquefling the neceffary information (b). But (b) Of this treatmsnt we have not inJeed often had occafion to complain. While mea of the firft eminence in church and ft.*ie have readily anfwcred the letters lliat were adJrcffed to them, and either communicated the ior- PREFACE. , It But while one part of our readers will regret that we have given no account of their favourite philofophcr, hero, or rtatcfman, others may be difpofed to remark, that wc have dragged from obfcurity the names of many pcrfons who v/erc no proper objcfts of fuch public regard. To thefe we can only reply, that, with the grcatcll: biographer of modern times, wc have long thought that there has rarely pafTed a life of which a faithful narrative would not be ufeful ; and that in the lives of the moil: obfcurc per- fons, of whom we have given any account, we faw fomcthing either conncfted v;ith recent difcoveries and public afiairs, or v/hich we thought capable of affording a leflbn to great multitudes in fimilar circumitances. Between eminent atchievements and the fcenes where they were performed, there is a natural and neccflary connexion. The charafter of the warrior is connected with the fields of his battles ; that of the legiflator, with the countries which he civilized ; and that of the traveller and navigator, with the regions which they explored. Even when we read of the perfons by whom, and the occafions on which, any particular branch of knowledge has been improved, we naturally, wifli to know fomcthing of, the places where fuch improvements were made. lliis curiofity, fo natural and fo laudable, has been frequently felt by ourfelves during Ihe compilation of this Work ; and to gratify it in others, we have fubjoined to the name of every confiderable place an account of its fituation, its climate, its foil, its peculiarities, its inhabitants, with their manners, cufloms, and arts ; its revolutions, laws, and government, with what- ever elfe appeared necelTary for the readers information, and at the fame time admif- lible fnto a work of fuch variety and extent. It is indeed probable, that by many of our readers we (hall be thought to have done too much rather than too little in this department ; and to have filled our pages with accounts of towns and villages not of fuSicicnt importance to demand general attention. But were it known how many of fuch places we have excluded from our Work, though recommended to us by fome of our mod obliging correfpondents, thofc who refleft upon the different tafles of man- kind, and confider that we wrote for the Public at large, would forgive us for having occalionally employed a few fentences in the defcription of others, which, whatever be their real importance, could not have been omitted without difappointing a very nu- merous clafs of readers. The knowledge of hifliory is fo important, not only to the flatefman and the legifla- tor, to whom indeed it is abfolutely necefTary, but likewife to every man who moves in a fphere above that of the loweit vulgar, that a Work profeffing to be a general re- pofitory of arts, fciences, and literature, would be exceedingly defective, if it did not contain fome information of the tranfaftions of thofe who have been in pofl'cfTion of the world before us ; of the varbus revolutions of flates and empires ; and of all the other means which have contributed to bring every thing into the flate in which we behold it. Fully aware of this, the compilers of the Encyclopaedia Britannica, befides giving a general view of univcrfal Iiillory and chronology, have enriched this Cklition with a fliort, though they hope luminous, detail of the progrefs of each particular nation, which from the remotefl period to the prefent time has afted a confpicuous part on the theatre of the world. The reader therefore will here find a very comprehenfive view of Civil History, ancient and modern, in all its branches. Nor have the hiflo- ries of Nature and Religion been neglefted. Of the former, it is not perhaps too much to fay, that in all the fubdivifions of its three great kingdoms, it will be found more tully, more accurately, and mure fcicntifically, detailed in this Work than in any other di(ftionary which has yet been publifhed. Of the latter, a brief view is given under the general article History ; the unavoidable dcfeifts of which are in a great mcafure b 2 Aipplicd information which was requefted, or politely ailignsd reafons for wilhing the lives of iheir friends not to be publilTied in the Encyclopidia Britannica, the Editor rccolkfts but two men, who maintained a fulWn lilence ; and ihefs he canuot confider as movins in a fphere much hijjhsr than his own. PREFACE. fuppIIeJ by the accounts that will be found, under their proper denominations, of all the coufklerable feifts and opinions which have prevailed in the religious world from tlic earlicll periods to the prefent day. Such was the plan of the fecond edition of the Encyclopaedia Britannica ; to which, as it fcems hardly capable of improvement, the Compilers of the third have, with a few flight variations, ftrit^lly adhered. Still, however, there was ample room for the efforts of all their indullry and all their learning ; for the rapid progrefs of the phyfi- cal fciences had rendered the labours of their predeceflbrs in many departments ufelefs. Befides the introduction of fome thoufands of new articles, there are not many of great importance, thofc in biography and geography alone excepted, which Ihuid in this Edition as they flood in the laif. Such recent difcoveries as could be introduced, have been mentioned with reference to their proper authors ; and, vhile the feveral fciences have been treated more fully and fyllemalically, greater care has been employed to trace the hirtory of each from its firll invention, and to apply them all to the arts of life. To accomplilh a talk fo arduous and fo important, neither labour nor expence has been fparcd. Literary journals ; the memoirs and tranfa(ftions of philofophic focicties ; and all the moft valuable diftionaries of arts and fciences, both in our own and in other languages, have been conllantly confulted. The works of the moft eminent au- thors, as well ancient as modern, who have written on any particular art or fcicnce, have been collefted and compared. Such of them as treat of topics, about which there is no room for controverfy, and are at the fame time fufceptible of abridgment, have been abridged with the greatefl care ; whilfl others, more concife and tenacious of their fubjefts, have been more clofely purfucd and more faithfully retained. Upon thofe branches of fcience on which the works of other authors furniflied nothing fit for the purpofe of the Editors, original cffajs and treatifes are inferted, which were compofed either by themlclves, or by fuch of their friends as they knew to be intimately ac- quainted with the fubjeft. On difputed points, whether in the phyfical or moral fciences, arguments and objections have been difplayed in their full force ; and of each of the various fefts into which the Chriftian church is divided, the account is generally given by the moft eminent clergyman of that feft to whom the Editors could find ac- cefs. After the utmoft exertions, however, of our attention and induftry, we are fcnfibic, perhaps more fenfiblc than any of our readers, tliat the Work paffes from our hands in a ftate far from perfection ; and that the man who fliall not difcover in the Encyclo- paxha Britannica miftakes, needlefs repetitions, and even culpable omiffions, will bring to the examination of it no great ftock of general knowledge. But for thefe ollences the Editors perhaps need no other apology than what will be furniflied by the nature of the Work and the hiftory of its publication. In a collection fo extenfive and multifarious, a few miftakes, repetitions, and omif- fions, might furely be paflcd over without feverity of cenfure, although the publicatioa had from the beginning to the end been fuperintended by the fame man ; but they •will be allowed to have been almoft unavoidable, when it is known that, after the AVork was far advanced, it was committed to the care of a new Editor, who, though he was in a great degree a ftranger to the contents of the printed volumes, found no clue of his predeceflbr's which could guide him accurately through thofe to be com- piled. We beg it to be underftood, that this obfervation is not made with a view to re- move any ihare of blame from the fecond to the firft Editor ; for Mr Colin Macfar- qulrar, who conducted the publication beyond the middle of the twelfth volume, was a man whom few who knew him will be difpofed to blame, and on whofe indu- ftrious integrity thofe who knew him beft muft admit that it would be difficult to beftow too much praife. Born in Edinburgh of parents refpeftable, though not afllu- cat, he was, at an early period of life, bound an apprentice to a printer. This pro- feffion gave him a tafte for fcicnce and literature, or rather furniflied him w-jth oppor- luiiitics. P R E F A C: E. tunities of cultivating the tafte which he derived from nature : and he foon became well acquainted with the mod popular writers in natural hiflory and in natural and moral philofophy. When he opened a printing-houfe of his own, rectitude of conduct quickly recommended him to friends and to employment ; and the unremitted profe- cution of his ftudies eminently qualified him for fupcrintcnding the publication of a new diftionary of arts, fcicnces, and literature ; of which, under the title of ENCYCi.op.tDiA Britannica, the idea had been conceived by him and his friend Mr Andrew Bell en- graver. By whom thefe gentlemen were affifted in digcfting the plan which attracted to that Work fo much of the public attention, or whether they had any aflillance, are queftions in which our readers cannot be interefled. Suffice it to fay, that Mr Mac- farquhar had the fole care of compiling the prcfent Edition ; and that, with the aid of a very few literary friends, he brought it down to the article Mysteries, in the twelfth volume, when he was cut olT in the 4.8 ih year of his age by a death which, though not fudden, was perhaps unexpected. His career was indeed fliort ; but of him it may be faid with as much propriety as of moft men, Nemo parum diii vixit, qui virtutis perfe^a pcrfcclo functus cfl inuncrc. Among his literary correfpondents was the Reverend Dr Gleig of Stirling, who had written for him various articles, of which fome were publiflaed during his lifetime and others in their order after his death. Thefe fliall be afterwards enumerated with thofe furniihed by other occafional contributors ; but they are mentioned at prefent, becaufe they account for that partial regard of Mr Macfarquhar for their author, which, on the death of the former, induced the truftees for his children, together with Mr Bell the furviving partner, to requeft the latter to undertake the ta/k Mhich their dcceafed friend had hitherto difcharged with fo much credit to himfelf. In this propofal, after fome hefitation on account of his dillance from Edinburgh, Dr Gleig acquiefced ; but wdien he entered on his new office, he found matters in a flate of no little confufion. Mr Macfarquhar, though his death had not been long expefted, had laboured long under a complication of difeafes; the confequence of which was, that the materials which he had prepared for the prefs were almoft exhaufled ; and of thofe vliich were firfl: called for, fome had not pafl'ed through his correfting hand. This circumftance may perhaps account for fome defefts and inaccuracies in that part of the Work, to which the fecond Editor looks back with the leaft fatisfaftion: but that which mud be his apology for feveral repetitions and omilfions, was the neglcft of his predecelTor during his laft illnefs to make an intelligible index to his own labours. From the want of fuch a necefTary guide, Dr Gleig was perpetually liable, notwith- ftanding his utmoft circumfpeftion, to give under one title an explanation of fubjcfts which had been before explained under another ; and to omit articles altogether, from a perfuafion that they had been difculled in fome preceding volume under the general fyitem to which they belong. Neither his repetitions nor omilllons, however, are fo many as fome have ftippo- fed them ; for what has been hallily cenfured as a repetition, is frequently nothing more than the neceflary relumption of fome important fubjeft. Availing himfelf of the excellence of the plan upon which the Encycloprodia Britannica is conilruft- ed, he took the opportunity, when he found any fyltem fuperiicially treated, to fupply its defefts under fome of the detached articles belonging to it.

That in the Encyclopaedia Britannica no account is given of fome things which fliould have a place in a .general repofitory of arts, fciences, and mifcellaneous litera- ture, muft be acknowledged ; but it mull likewifc be acknowledged that fuch omiiEons are neither numerous nor very important ; for many fubjefts, which have been fup- pofed to be omitted, arc trcatal under titles different from tliofe under which they have Nil PREFACE. hnve been looked for. Thus the method of calculating compound interefls, which one of our correfpondents cannot find in our Work, 'a taught in the article Algebra ; that of coaling mirrors, of which another complains that no account is given, will be found under the term Foliating ; and though it may be true, according to the peevifli remark of a third, that the reader is nowhere dircftly in(hni(?>cd how to grind optical giafles, yet if he read the article Gi.Ass-Gr/W//?^, and undcrlland the doclrine of lenfes as laid down in the article Optics, he will cafily, if an artift, difcover a method of perlorraing that operation for himfelf. Omissions, however, there are towards the end of the Work j not the confequence of carcleilhefs, but the offspring of neccility. In an addrcfs to the Purchafcrs of the Encyclopa-dia Britannica, fubjoincd to the ninth volume, the proprietors gave a rafli promifc to comprehend the whole of their undertaking within the limits of eighteen ; and if intervening difcovcrics fhould make it ncceflary, to enlarge the iafl volumes in quantity without any additional charge to Suhfcribers. That the promife was rafli, a moment's reflection fliould have taught them ; for in the prefcnt rapid progrefs of phyficrd fcience, when new difcoveries are daily made, it was obvioufly nnpoiFible, at fo early a period, to afcertain with prccifion how many vo- lumes would be neceffary to bring a Work of fuch comprehenfive variety to the utmofl perfection of which it is capable. This was indeed foou difcovered ; but the proprie- tors fhrunk not from their engagement, which they determined to fulfil to the utmoft extent of its meaning, till the additional tax, which in 1795 vi'as laid upon paper, in- volved them in diflicuities which they had not forefeen. By the a.'\L)DON, is the name which St John in the Revelation gives to the king of the loculls, tlie angrl of the bottomlcfs pit. The infpired writer fays, this word is Hebrew, and in Greek lignifles 'A-T«>,>iaT, /. e. a dcjiroycr. That angtl-king is thought to be Satan or the devil : but Mr le Clers thinks, with Dr. Hammond, that by the locufls which came out of the abyfs, in.iy be undcrllood the zealots and robbers, who miferabljT afllifted tiie land of Judca, and laid it in a manner w3(le before Jerufalcm was taken by the Romans ; and that Abaddon, the king of the locufls, may be John of Gif- rhala, who having trcacheroully left that town a little before it was furrendf red to Titus, came to Jerufalcm, where be foon beaded part of the /e.ilois, who acknow- ledged him as their king, wliilfl the relt would not fubmit to him. This fubdivilion of the zealot pany brought a thoufand calamities on die Jews. ABADIR, a title which the Carthaginians gave to gods of the firft order.

ABANTES, a people who caine originally from Thrace, and fettled in Phoccca, a country of Greece, where they built a town which ihry called Aba, after the name of Abas their leader; and, if we may credit foinc ancient authors, the Abantcs went afterwards into the illand Euboea, now called Negropont : others fay the Abantes of Euboea came from Athens. The Aban- tcs were a very warlike people, dofing with their ene- mies, and fighting hand to hand. ABANTIAS, or Abantis (anc. geog.), a name of the illand Euboea in the Egean fca, extending a- long the coaft of Greece, from the promontory Su- nium of Attica to ThelTaly, and feparaicd from Bceo- tia by a narrow ftrait called Euripus.

ABARIS, the Hyperborean; a celebrated fage of antii]uity, whofe hiitory and travels have been the fub- jciJl of much learned difcuffion. Such a number of fa- * JiBiblichi bilious ftories* were told of him, that Herodotus him- yitcPjthag felf feems to fcruple to relate ihem. He tells us only,-)- t ^'•>- "• that this Barbarian was faid to have travelled with an c»p. 36. arrow, and to have taken no fuftenance: but this docs not acquaint us with tiie marvellous properties which were attributed to that arrov/ ; nor that it had been given him by the Hyperborean Apollo. M'iih regard to the occafion of his leaving his native country, Har- } Under pocration| tells ns, that the whole ear:h being infclled the word with a deadly plague, Apollo, upon being conftdicd, ACry of the aflalliuation-plot. He had great natural abilities, which he improved by true and ufeful learning. He was a niofl zealous defender of the primitive do,5lrinc of the Protcftants, as appears by his writings ; and that llrong nervous eloquence, for which he was fo remarkable, enabling him to enforce the doiflrines of his profeifion, from the pulpit with great fpi- rit and energy. He publiflied fcveral works in French that were much eftcemed ; the principal of which are, A Trcaiife on the Truth of the Chriftian Religion ; The art of Knowing one's Self; A Defence of the BritiOi Nation ; The Deityof Jcfus Chrift eflential to theChri- flian Religion ; The Hiftory of the laft confpiracy in England, written by order of king William III. ; and The Triumph of Providence and Religion, or the open- ing the Seven Seals by the Son of God. ABBAS, foil of Abdalmothleb, and Mahomet's nn- cle, oppofed his nephew with all his power, cfteeming hiin an impoftor and infidel ; but in the fecond year of the Hrgira, being overcome and made a prifoner at the battle of Bendir in 623, a great ranfom being de- manded for him, he reprefented to Mahomet, that his paying it would reduce him to poverty, which would redound to the didionour of the family. But Mahomet having been informed of Abbas's having fecretcd large fums of money, alked him after the purfes of gold lie had left in his mother's cuflody at Mecca. Abbas, up- on this, conceiving hiin to be really a prophet, cm- braced his new religion ; became one of his principal captains; and Caved his life when in eminent dangerat the battle of Hcnain, againll the Thakefitcs, foon after the rcduiJlion of Mecca. But bclidcs being a great commander. Abbas was a famous doJlor of the Muf- fuliuan law, infomuch that he read lectures upon every chapter of the Koran, as his nephew pretended to re- ceive them one by one from heaven. He died in 652, and his memory is held in the highcfl veneration among the Miiliiilmans to this day. /4bul Ahhas, furnamcd Sajfah, was proclaimed kha- lif ; and in him began the IJynafty of the ABBAbSlDKS, who poirellcd the khalifate for 524 yeari ; and there were 37 khalifs of this race who fuc- cecded one another without interruption. ABBE, in a monaftic fenfe, the fame with Abbot. Abbe, in a modern fcnfe, is the name of a curious popular character in France, very much mentioned, but very little known, in Britain. The term is not to be rendered in our language, as the exillence of the being which it denominates is pofterior to the reforma- tion, and no fuch character was known among the Ro- manills till about a century and a half ago. Abbes, according to the Itrit^eft definition, are pcr- fons who have not yet obtained any precife or fixed fettlement in church or flaie, but molt heartily with for and would accept of either, juft as it may happen. In the mean while, their privileges are many. They are admilFible in all companies, and no degradation to the belt, nctwithltanding they are fomctimes found in the worft. Their drefs is rather that of an academic, orofa proftlTed fcholar, thanof anecclefiaflic ; and, ne- ver varying in colour, is no incumbrance on the pocket. Thcfe abbes are very numerous, and no lefs ufeful. They are, in colleges, the inftrudors of youth ; in pri- vate families, the tutors of young gentlemen ; and many procure a decent livelihood by their literary and witty compofiiions of all kinds, from the profoundeA philo- fophy to the moil airy romances. They are, in Ihorr, a body of men who polfefs a fund of universal talents and learning, and are incellantly employed in the culti- vation of every various branch of literature and inge- nuity. No fubjeft whatever efcapcs them ; ferious or gay, folid or ludicrous, facred or profane, all pay tri- bute to their refearches; and as they are converfant in the lowell as well as the highelt topics, their fame is equally great in the learned and in the fcribbling world. A didinguifhing part of their character, too, though we Ihall but (lightly touch it, is their devotion to the fair fex : whofe favourites, in return, they have the ho- nour of being in the molt enviable degree ; the wit and fmartnefs for which they are ufually remarkable, being ju(t the very things that fuit the French ladies. — In fine, thefe abbes are fought after by inoft people, on various accounts ; as they are equally men of bufinefs and plea- furc, not lefs expert in the moll ferious tranfaiftions, than fond of enjoying their (hare in whatever occupies the gay world. Hence they diligently frequent ail public fpec- tacles, which are thought incomplete w iihout them ; as they compofe the moll intelligent part of the company, and are the nio.t weighty approvers or condemners of what palFes in almolt all places. ABBESS, the fuperior of an abbey or convent of nuns. The abbcfs has the fame rights and authority over her nuns that tlie abbots regular have over their monks. The fex indeed does not allow her to perform thefpiritual funi5lion<; annexed to the pritfthood, where- with the abbots isufually inverted ; but there are inftarces of fomc abbclTcs who have a right or rather a privilege, t« ABB [ 8 ] ABB Abbfvnie, to eommiffion a pricft to ncl for them. They have even Abbey, a kind of epifcopal jurifdidion, as well as fonie abbots * ' who are exempted from the vifitation of their dioccfans. Mincne, in his trcatifc on ilic rights of the Church, obfc-rves, that fome abbelTes have fortnerly conf«lTcd their nuns. But he adds, that their cxceflivc curiofiiy cariicJ them fuch lengths, ih.it there arofe a necelhty of checking it. However, St Balil, in his Rule, allows ti;e abbefs to be prcfciit with the prieft at the confcflioii ot her mins. ABBEVILLE, a confiderable city of France in Picardy, and the C3pi'.:il ot Ponihicu; the river Somiiic runs through the middle of it, and divides it into two psrts. It has a collegiate church and twelve pariih- chiirches; the moltconfiderablcof which are St George's and St Giles's, befides a great number of raonaltcrics and nunneries, a bailiwic, and a prcfulial court. It isa fortified town; the walls are f.ankcd with hallions, and fiirroundcd by large ditches ; and was never yet taken ; from which circiimftance it is Ibmetimes called the Mj:.!i!i Tc-vtv;. The coiintry about it is low, marthy, end dirty. It is pretty well peopled, and is famous lor its woollen manufadory. The cloths and lliifTs made there are faid to be mnv little inferior to thole of Eng- land and Holland. The work, however, is alfifted by the clandeftinc importation of Englilli and Irilh wool, and workmen from Great Britain. It is about fifteen sillies cart of the Briiilli channel, and Ihips n'.iy come Irom thtncc by the river Somme to the middle of the town. E. Long. 2. 6. Lat. 50. 7. ABBEY, a monaftery, or religious houfe, governed by a faperior under the title ai al-bot or ahbejs. y^^it^/ differ from priorhs, in that the former are un- der the diredion of an abbot, and the others of a prior : but abbot and prior (we mean a prior conventual) are much the fame thing, differing in little but the name. Fauchetobfcrvesjthatin the early days of the French monarchy, dukes and counts were called abbas, and duchies and counties abbess. Even fome of their kings .ire mentioned in hillory under the title of abbots, Phi- lip I. Louis VI. and afterwards the dukes of Orleans, arc called abbots of thi vtonaflcyy of St Aigitan. The dukes of Av]uitain were called abbots of thevionaflery of 5/ Hilary, at PoiP.Urs ; and the earls of Anjou, of i/ Aubin, &c. Monafteries were at firft nothing more than religious linufes, whither prrfons retired from the buflle of the world to fpend their time in folitudc and devotion. But ihcy foon degenerated from their original inflitution, and procured large privileges, exemptions, and riches. They prevailed greatly in Britain before the reforma- tion ; particiLirly in England : and as they increafed in riches, fo the Aate became poor ; for the lands, which thefc regulars poffeffed were in viortua manu, i. f. could never revert to the lords who gave them. This inconvenience gave rife to the llatutes againft gifts in mortmain!, which prohibited donations to thefc re- liffious honfes : and Lord Coke tells us, that feveral lords, at their creation, had a claufc in their gi'ant, that the donor might give or fell his land to whom he would {^ixaptis viris religiofis & Jtii/ais) excepting monks and jews. The places wrre wholly abolilhcd in England at the lime of the Reformatioti ; Henry VIII. having firft appointed vifitors to infpeft into the lives of the monks and nuns, which were found in fome places very Abbey, difordtrly : upon which, the abbots, perceiving their Abbej- dilfolution unavoidable, were induced to refign their . t"'y''- houfesio the king, who by that means became invelled " with the abbey-lands: thefc svcre afterwards granted to different perfons, whofc defcendents enjoy them at this day : they were then valued at 2,853,000/. per annum, an immenfe fum in ihofe days. Though the fuppreffion of religious houfes, even con- fidcred in a political light only, was of a very great na- tional benefit, it mufl be owned, that, at the time they flourillied, they were not entirely ufclcfs. Abbeys ormo- nafteries were then thercpoiitories, as well as the femi- naries, of learning ; many valuable books and national records, as well as private evidences, have been preftrv- edin their lioraries ; the only places wherein they coulJ have been fafcly lodged in ihofc turbulent limes. Many of thofe, which had efcapcd the ravages 01 the Danes, were deflroyed with more than Gothic barbarity at the diiToliition of the abbeys. Thefc ravages are pathetical- ly lamented by John Bale, in his Declaration upon Lc- land's Journal 1549. " Covetoufncfs," fays he, " was at that time fo bufy about private commodity, iliat public wealth, in that mod ncceffary and of rcfpe^, was not any where regarded. A number of tliem which pur- chafed thefe fuperftitious manfions, referved of the li- brary-books, fome to ferve their jacks, fome to fcour the candlelticks, and fome to rub their boots ; fome they fold to the grocer and foap-feller ; and fome they fcnt over fea to the book-bindtrs, not in fmall numbers, but in whole Ihips full ; yea, the univerfiiics of this realm are not clear of fo delegable a faft. 1 know a merchant that bought the contents of two noble libra- ries for 40s. price ; a ihame it is to be fpoken ! This ftuffhath he occupied inllead of gray paper, by the fpace of more than thefc ten years, and yet ht hath ftorc enough for as many years to come. 1 (hall judge this to be true, and utter it with hcavinefs, that neither the Britons under the Romans and Saxons, nor ytt th.e Englifli people under the Danes and Normans, had ever fuch damage of their learned monuments as we hayc fecn in our time." In thefc days every abbey had at Icaft one perfon whofc oiEce it was to inflruft youth ; and the hiftori- aiis of this country are chicfiy beholden to the monks for the knowledge they have of former national events. In thefe houfes alfo the arts of painting, architeflure, and printing, were cultivated. The religious houfes alfo were hofpitals for the fick and poor ; affording likewife entertainment to travellers at a time when there were no inns. In them the nobility and gentry who were heirs to their founders could provide for a certain number of ancient and faithful fervants, by procuring them corodies, orflated allowances of meal, drink, and clothes. They were liktwife an afylum for aged and indigent perfons ot good family. The neighbouring places were alfo grea:ly benefited by the fairs procured for them, and by their exemption from foreft-laws ; add to which, th it the monaflic eftates were generally let at very eafy rents, the fines given at renewals in- cluded.

In the preface to a piniplilct he publiihcd, the I'ollowiiij; fpc- ciiiun of riJiculoiis riattery occurs : Speaking oi the king, he fays, " wliofc lilc haih been io immaculate atuluiifpoticd, Stc. thatcvt n nulice iifclt, whi-h leaves rothi.i^ iinfrarcheJ, could never iui>l true ijUmilh in it, nor call probable af^Mrfion on it. — Zcaloui as iJa- vid i learned and wife, the Stiowoi: of onr a^je ; rcli- j;ious as Jolias ; cartful of fpreading Chrill's faith as C'onilantine the Great ; jnltas Mofcs , undcidedin all Jiiswaysasa Jehofaphat uiidHc^iekias ; full of clemen- cy as another Theodoiius." — If Mr Walp^Ic had fecn this pafliige, he certainly would not have faid, that " hoiicll Abbot could not rtatttr." His great zeal for the I'rotellant Religion made him a Hrenuous promoter oi tlie match between the elector Palatine and the Princefs JLlizabeth ; which was accor- dingly concluded and folemni/cd the 1 4''' of February 161:, the archbilhop performing the ceremony on a fla^c erected in the royal chapel. In the following year happened the famous cafe of divorce betwixt the lady Francis Howard, daughter of the earl of Suffolk, and Robert earl of Kllcx: an attair which has been by many confidercd as one of the greatell blcmilhes iu king James's reign ; but the part therein acted by the archbilliop added much tothe reputation he had al- ready acf^uired for incorruptible integrity. I he matter was by the king referred to a court of delegates. The nrchbilhop law plainly, that his Majcrty was very de- firous the lady Ihould be divorced : but he was, in his own judgment, dircflly aguinil the divorce. He la- boured all he could to extricate himfelf from thisdiiR- culty, by having an end put to the caufc by fomc o- thcr way than by fcntence : but it was ta no purpofe : for thofc who drove on this affair, had got too great power to be retrained from bringing it to the conclu- f.on the king defired. The archbilhop prepared a fpccch, which he intended to have fpoken againd the nullity of the marriage, in the court at Lambeth ; but he did not make ufe of it, becaufe the king ordered the opinions to be given in few woras. He continued, however, inflexible in his opinion againflthe divorce ; and drew up his reafons, which the king thought fit to anfwer himfelf. It need fcarce be added, that fen- icnce was given in the lady's favour. In 161 1, the king publiihcd a declaration, which he ordered to be read in alhhe churches, permittingfports and pallimes on the Lord's day : this gave great uneafinefs to the archbifhop , who, happening to be at Croydon when it came hither, had the courage to forbid its being read. Being now in a declining flate of health, the arch- bilhop ufed in the fummer to go to Hamplhire for the fjke of recrcaiion ; and being invited by lord Zouch to hunt in hii park at Bram/.ill, he met there with the grcateft misfortune that ever bcfel him ; for he accidentally killed the game keeper by an arrow from a crofs-bow which he (hot at one of the deer This accident threw him into a deep melan- choly ; and he ever afterwards kept a moiitiily falton •F 11- •« Tuefday, the day on which this fatal raifchance hap- chiircS-Kiil.P''""^'^' ^'-^ "^ fettled an annuity of 20 . on the wi- tc-iit xviii, dow. There were feveral perfons who took an ad- p. 87- 2 vantage of this misfortune, to IcflTen him in the king's Abbot favnir ; bit his Majtlty laid, "Aw angtl might have — mifcariiea in tliis lo. t." His cneiaits alledging that he had incurred an irregularity, and was thereby inca- pacitated lor performing the oihce of a primate j the king directed a commiiiioa to ten peifons lo inquire iuiuihis matter. 1 he refult, however, was not fatisfaclory to his Graces' enemies; it being declared, that as the mur- der was involu.itary, he had not lorteited his archic- pifcopalcharatter. The archbiuiop thenceforward fel- dom aililled at the council, being chielly hindered by hib inhrmities ; but in the king's hit illniTs he was lent tor, and attended wi'.h great conllancy tiil liis Majclly expired on the 27''' of March 162;. He penormed the ceremony of the coroa.lion of king Chailts I. thotigh very intirm and much troubled with the gout. He was never greatly in this kMg'cfavour ; and the duke of Buckingham being his declared cut my, watched an opportunity of making him feel the wiighc of his difpleaf ire. 1 his he at lait accomplilhed, upon thearchbilhop's rcfuiing to licence afcrmon, prcached by Dr Si jthorpc to jultify a loan w hich the kiig had demanded, and pregnant vvith principles which tended to overthrow t.hc conllitution. 'I'he archbilhop was imnicdiately after ful'pended from all his functions as primate ; and i hey were excrcifed by certain biihopscom- miilioned by the kii:g, of whom Laud, the archLilhop's enesiy, ana afterwards his fuc-.elibr, was one : while the only caufe alligned for this procedure was. That the archbilhop could not at that time perfonally attend thofd fervices whicli were oiherwife proper for his cognifancc and direction. He did not, however, re- main long in this lituation ; for a parliament being ab- foUitely necelfary, liis Grace w as fent for, and reltore J to his authority and juriluiction. But not proving friendly to certain rigorous meafures adopted by the prevailing church-party, headed by Laud, whole power and interefl at court w ere now very couliderable, his prefence became unwel ome there ; fo that upon the birth of the Prince of Wales, afterwards Charles II. Laud had the honour to baptize him, as dean of the chapel. The archbilhop being worn out with cares and intinnities, died at Croydo'i, the jth of Augufl 163:, aged 71 years ; and was buried at Guilford, the place of his nativity, and where he had endowed an holpital with lands to the amount of 500-. per annum. A llatcly monument was erected over the grave, with the efiigy of the archbilhop in his robes. He thewedhimfelf, in moll circum fiances of Lis life, a man of great moderation to all parties ; and was de- li roust iiat the clergy (hould attract the ellcem of the lai- ty by the fandiry ol their manners, rather than claim it as due to their lanction. His notions and principles, however, not fuiting the humour of fome writers, have drawn upon him many fcvere retieclions ; particularly, which is to be regretted, from the earl of Clirendoii. But Dr Welwood has done more ju:;ice to his merit and abilities*. He wrote feveral tracts upon various fnbjecls; and, as already mentioned, tranllated part of the New Teflameni, with the reft of the Oxford di- vines, 161 1. It is proper to obferve here, that there was another writer of both his names, who fiourilhcd fomevvhat later. This George Abbot wrote y/ l'ar,ii'hr,!p on 'Memoirs, 8vo. 1 70c, p. 38.

Upon his tirft fermon at Worccfter, he was chofcn lec- turer in that city, and icon after redor of AU-faiuts in the fame place. John Stanhope, £fq ; happening to hear him preach at I'aiirs-crofs, was fo plcafcd uith him, that he immediately prcfcntcd him to the rich living of Biagham in Nottinghimfliiro. In 1597, he took his degree of doctor in divinity : and, in the beginning of king James's rtign,\vas appointed chaplain in ordinary to his Majclly ; who had fuch an opinion of him as a writer, that he ordered the doifter's book Di AiA'ichrifio to be printed with his own conimcnt:.ry upon part of the Apocalypfe. In 1609, he was elcJlcd mailer of Baliol College; wlrich triift he difcharged with the ut- inoft care and aliiduity, by his frequent IcChires to the fcholarSjby his continual prefence at public exercilcs, and by promoting temperance in the fociety. In No- vember 1610, he was made prebendary of Normanton in the church of Southwell ; and, in 1612, his Majclly appointed him regius profcifor of divinity at Oxford. The fame of his lectures became very great ; and ihofe which he gave upon the fupreme power of kings againft Bellarmine and Suarez, fo much plcafcd his Nlajclly, that, when the fee of Salilbury became vacant, he na- med him to that bilhopric, and he was confccratcd by his own brother at Lambeth, December 3, 1615. When he came to Salifb.iry, he found the cathedral running to decay, through the negligence and covct- oufntfs of the clergy belonging to it: however,he found means to draw live hundred pounds from the prebenda- ries, which he applied to the reparation of this church. He then gave hinifelf up to the duties of his function with great diligence and afiiduity, vililing his whole dioccfc in perfoa, and preaching every Sunday whilll health would permit. But this w^s not long: for his fc- dentary life, and clofc application to fludy, brought upon him the gravel and ilonc ; of which he died on the ad of March 161S, in the tifty-cighth year of his age ; hiving not filled the fee quite two years and three months, and being one of the five bilhops which Salif- bury had in fix years.

Alexan- dertheGreat having depofcd Strato, inquired whetlicr anyofilie raceofCinyras was living, that he might fct him on the throne. It was generally tlioiiglu that the whole race was extincb : but at l.ill AbJalonymus was thought of, and mentioned to Alexander ; who imme- diately ordered fome of his foldiers to fetch him. They found the good man at work, happy in his poverty, and entirely a flraiiger to the noifcof arms, with which all Afia was at that time diilurbed ; and they could fcarcely pcrfuade him that they wCre in carnell. Alex- ander was convinced of his high dcfcent by tlie dig- nity that appeared in his perfon ; bat was defirous of learning from liim in v/hat manner he bore his poverty. " I Willi" faid AbJalonymus, " 1 may bear my new condition as well : Thel'e hands have iupplied my ne- celiities: I have had nothing, and I have wanted no- thing."

ABELARD (Peter), one of the mod famous doc- tors of the twelfth century, was born at Pcliis near Kantz, in Britany : he was well learned in divini y, philofophy, and the languages ; but was particularly diftinguilhcd by his Ikill in logic, and his fondnefs for difputations, which led him to tiavel into feveral pro- vinces in order to give public proof of his acutcncfs in that fciencc. After having baffled many antajonifls, he read lectures in divinity with great applaufe at Paris ; where he boarded with a canon whofe name was Ful- bcrt, and who had a very beautiful niece named He- loife. Tlie canon ardently wilhed to fee this young lady make a figure among the learned, and Abelard was made her preceptor : bat inftcad of inllruding her in tiie fcienccs, he taught her to love. Abelard now performed his public functions very coldly, and wrote nothing but amorous verfes. Heloife proving with child, Abelard fent her toa lifter of his in Britany, where Ihc was delivered of a for.. Tofoftcn ilie canon's anger, he offered to marry Heloife privafly ; and tluoldman was better picafed with tIiepropofahli;in the nicee.who.from alingularexcefsofpa!iion,chofc to be Abelard 'smillrefs rather than his wife; She married, however, but ufed of- ten to protell upon oath that fhcwas fingle,which provo- ked the canon to ufe her ill. Upon this, Abelard fent her to the monaftery of Argcnteuil; where flic put on .1 religious habit, but did not take the veil. Heloifc's re- lations confidcring thisas a fecond treachery, hired ruf- lianS, who, forcing into his chamber in the dead of the night, emafeulated him. This infamous treatment made him fly to the gloom of a eloifter. He allumed the mo- naftic habit in the abbey of St Dennis ; but the difor- dcrs of that houfe foon drove him from thence. He was-aTtcrwards charged with hcrcfy ; but after fcvcral perfecutionsforhis religious fentiments, he fettled in a folitudein the dioccfc ofTroies, where he built an ora- tory, to which he gave the name of the Paraclct. He was afterwards chofcn fuperiorof the abbey of Ruis in the dioeefeof Vannes : when the nuns being expelled from the nunnery in which Heloife had been placed, he gave her his oratory ; where llie fettled with fome of her lifter nuns, and became their priorefs. Abelard mixed the philofophy of Ariltotlc with his divinity, and in 11 40 was condemned by the council of Rhcims and Sens. Pope Innocent II. ordered him to be imprilbncd, his books to be burnt, and forbid him ever leach in', again. However, he was foon after pardoned, at the folicitationof Peter the Venerable, who received him into his abbey of Clugni, where he led an exem- plary life. He died in the priory of Marcellus at Cha- lons, April 2\, 1142, aged lixty-tliree. His corpic was fent to Heloife, who buried it in the Paracler.

The bilhopric was founded in the time of uavidl.as abovcmentioncd. 1 he cathedral had anciently tworows of fione pillars acrofs the church, and three turrets; the ftecfle, which w as the largeft of ihefe turrets, reli- ed upon an arch, fupported by four pillars. In this ca- thedral there was a line library ; but, about the year I j6o, it was almoll totally dcllroyed. But the capital building is the king's-college, on the fouth lide of the town, which isalarge and flatcly iabric- Itis builtround a fquare, with cloiltcrson the fouth lide. The chapel is very ruinouswiihin; but there llill remaiasfome wood- work of exquiliteworkmanihip. This was preferved by the fpirit of the principal at the lime ot the reformati- on, who armed his people and checked the bliiid zeal of the baroris of the Mearns ; who, after Itrip, iug the cathedral of its roof, and robbing it of the bells, were goi ig to violate tliis feat of learning. They ihipped their facrilegious booty, w ith an intention of cxpoling it to fale in Holland : but the vellel had llarcely gone out of port, when ir pcrilhcdina liormwitli ail its ill- gained lading. The lleeple is vaulted wiili a double crofsarch ; above which is an imperial crown, fupport- ed by eight ftoiu-pilUrs, and clofed w ith a globe and two gilded erodes. In the year i6;i this lleeple was thrown down by a florm, but was fc.on after rebuilt ia a more Aately form. This college was foandcd ia 1494, by William Eli>liinflo:i bilhop of this place, Abfrdeen.

The New Town i» the capital of the ihire of Aber- deen, t'orlargciicls, trade, ana beauty, it greatly ex- ceeds any town in the north 01 Scotia. id. It is built OH a hill or riling ground, and lies on a fmall bay formed by the Dee, deep enough for a lliip of 2CO tons, and above two miles in circumference — The buildings (which are of granite from the neigh- bouring quaries) are generally four llories high ; anj have, liJi the molt part, gardens behind them, which gives it a beautiful appearance. On the high-llrect is a large church, which formerly belonged to the Iran- cifcans. This church was begun by iJiil.op \V illiani Llphinlton ; and tinill.ed by Ga\inus Dunbar, bilhop of Aljcrdeen, abjut the year t 5&0. Bilhop Dunbar is faij liivewife to have built the bridge over the Dee, which coalillsof feven arches. In ihe niidiileof Calue-Ilreec is an octagon building, with neat bas-relievos of the kings of Scotland from James 1. to James VII. The town-houfc makes a good figure, and has a handlome fpirc in the centre. The grammar-lchoolisa low but neat building. Gordon's hofpiial is handlome ; in front is agood liatue of the founder : it maniains forty boys, whoarc apprenticed at proper ages. The infirmary is a large pbiin building, and fends out between eight and nine hundred cured patients annually, but the chief public uuilding ii: thenewtown isthe .Marifchal- coUcge, founded by George Kicth carl of Marifchal, in the year 1593 ; but lince greatly augmented with additional b.iilUings. There arc about 1 43 ftudents btlongi.ig to it. In both tiie Mariichal and King's college the languages, mathematics, natural philolb- phy, divinity, ice. are taught by very able profellbrs. The convents in .-iberdeen were : Oneof Mathurines, orof the order of the Trinity, founded by William the Lion, whouied in 1314 ; another of Dominicans, by Alexander II. ; a third of Obfcrvantir.es, a building of great length in the middle of the cily, founded by the citi/.er.s and Mr Richard Vans,&c. ; and a fourth of Carmelites, or White Kriars, founded by Philip de Atbuthniit in 1 350. Aberdeen, including the Old Town, is fnppofej to co;uain 25,000 people. Its trade is conllderablc, but might be greatly extended by an atte/ition to the white lilheries. The harbour was long a great detriment to its trade, and ocealioncd the lofs of many lives and much pro- perty. A Hrangcr could'r.ever depend upon t^ndin;; it as he left it ; while vcilels lay at anchor in the read till the tidcflioulUiuakc, they have often been wrecked by dorms A » E I 16 ] A li E •\hcrJcen.

By the ealkrly and north- call llorms the faud was driven in a long ridge acrol's tlic harbour'smouth, aid lornicd what was called the I'ur. Upon this bar thcdepihof watcrat lowtiJe wasfomciinics not above ihrce feet. Clearing away the faud, though but a par- tial and temporary remedy, was a matter of great ex- pence to the comnumily : If it was cleared one week lb as to have live or lix feet of water at ebb, a frelli florin the next week undid all that had been done. The town at lall came to a refohition of creeling a llrong pier on the north fide of the harbour. This pier is I 200 feet in length, and gradually iacrealcs in tliick- nefs and height as it approaches the fea, where the head or rounding is 60 feet diameter at the bafc, and the perpendicular elevation is 3S feet. The whole is built of granite, the mofl durable flonc known : many of the outlide Hones arc about three tons weight, with hewn beds. It was built under the direction of Mr Smcatoii ; and the expcncc, anioiinting to above 17, cool, is defrayed by doubling the harbour-dues, whicli are ehieHy paid by the inhabitants. A little to the foutli of the bar, they have now a depth of 7 fathoms at low water ; and at the har- bour mouth, from eight to nine fithoras, where they had formerly but a few feet. Aberdeen once enjoyed a good lliareoftlie tobacco trade. At prefcnt, its importsare from the Ualtic, and a few merchants trade to the Weft Indies and North America. Its exports arc ilockings, thread, falmon, and oatmeal. The firft is a mofl important article, as appears by the fallowing ftatc of it. For this manu- failure, 20,8co pounds worth of wool is annually imported, and 1600 pounds worth of oil. Of this wool arc annually made 69,333 dozen pairs of Jlock- iiigs ; worth, atanavarage, il. ios./>ct dozen. Thefe are thcworkof the country-people in almoflall partsof this great couiity, who get 4s. />;/• dozen for fpinning, ' and 14s. /><:r dozen for knitting ; fo that there is an- nually paid them 62,5291. 14. There is, befidcs a- bout 2000I. value of Hockings manufaiflured from the wool of the county. The thread manufat'lure is ano- ther conliderablc article, though trifling incomparifon ■of the woollen. The falmon filherics on the Dee and the Don arc a good branch of trade. About 46 boats, . and 130 men, are employed on the firfl ; and, in fome years, 167,000 lb- of filh have been fent pickled to Loudon, and about 930 barrels of faltcd fifli exported to France, Italy, See. — The fiOiery on the Don is far lefseonlideraMc. The fifli of this river are taken iu cruives above the bridge; a pra<;Hce contrary to the ancient laws of the kingdom, irnlefs v/here the nature of the water rendered the nct-tilliciy impracticable. The inhabitants likewifc exjrart conlidcra'olc quanti- ties of pickled pork, which they fell to the Dutch for victualling their Eafl India (liips and men of war ; the Aberdeen pork having the reputation of being the beil curcJ of "any in Europe for keeping on long voyages. " It is however remarkable, (Mr Kr.ox obfcrves), that there is not a tingle decked vcfftl fitted out from Aberdeen forthe herring or white iiflicrics: here is now 3 an excellent iiarbonr ; an aclivc people, couverfant in Abcrdctui- tradc, and pollclled of capital , fealcd within (ix hours 1'ir<; failing of Long Fortys, and two days failing of the Shetland Illcs. This inattention is the more extraor- dinary, as the exports of Aberdeen, thougii very con- fiderable, do not balance the imports in value. 'Ihc herring and wliile iiiheries, tlierefore, ifprofecutcd with vigour, cured and dried with judgment, wouldiiot only extend the fcale ot exports, but alfo furnilh the outward bound vellcls with Ireights, and better alliirt- -mentsforihe foreign markets. The falnionof the Dec and Don are taken in great abundance, cured in the higliell perfctlion, and greatly valued at the Kuropean markets. If the merchants, in addition to tlufc, ihould alfo export the cargoes of 50 or 60 veliels conftaiuly employed in tiie herring and white filhenes, the port of Aberdeen would in a few years become the nioft ce- lebrated mart of lidi now exifling."

ABERRATION, in aftronoiny, a fmall apparent motion of the fixed ftars difcovered by the late Dr Bradley. Tlic difcovcry was made by accident in the year 1 72 j, when Mr Molyncux and Dr Bradley began to obferve the bright ftar in the head of Draco, mark- ed > by Bayer, as it paifed near the zenith, with an inflrument made by MJ Graham, in order to difcovcr the parallaxof the earth's annual orbit ; and, after repeated obfervations, tliey found this liar, about the beginning of March I7J6, to be 20" more foutherly than at the time of the firft obfervation. It now indeed iecnie d to 1\ave arrived at its utmoft limit fouthward ; bccaufc, in fevcral trials madeabout this time, no fen fible difference vasobfcrved in its lituatiou. By the middle of April, it appeared to be returning back again toward the north i and, about tlic beginning of lunc, it palled at the fame diftancc from the zenith as it had done in De- cember, wlien it was firflobfcrved : in September fol- lowing, it appeared ;9" more northerly than it w as in March, juft the contrary way to what it ought to appear by the annual parallax of the ftars. Tliis un- expcifled phmoracnon perplexed tlic obfervers very much ; and MrMolyneuxdied before the true caufc of it Vol. I. Abcx. 17 ] ABE was difcovered. After iliis, Dr Bradley, wiih another Alerrition inftrumcnt more exai.'t and accurately adapted to this parpofcjobfervcd the fame appearaaces not only in tiiat but many other ftars : and, by the great regularity that appeared in a ferics of obfervations made in all parts of tlic year, the Dodtor was fully faiiilied with re- gard to the general laws of the phenomena; and there- fore endeavoured to lind out the caafe of them. He was already convinced, that the apparent motion of tlic ftars was not owing to a nutation of the earth's axis. The next thing that offered itfelf, was an alteration in the dircilion of the plumb line, witli which the ia- ftrumciit was eonftantly rcftified ; but this, upon trial, proved infuliicient. Then he had recourfe to what rc- fraftion might do ; but here alfo nothing fatisfaclorjr occurred. At laft this acute aftronomcr found, that the phenomena in queftion proceeded from the progreffivc motion of light, and the earth's annual n.otioii in its orbit : for he perceived, that if light was propagated in time, the apparent place of a fixed objeit would not be the fame w'hcn the eye is at reft, as when it is mo- ving in any other direftion than that of the line paf- fing through the eye and object ; and that, when the eye is moving in ditferent directions, the apparent place of the object would be different. Aberration, in optics, isufed to denote that error or deviation of the rays of light, when inflected by a lens or fpcculum, whereby they are hindered from meeting or .uniting in tlic fame point. There are two fpecies of the aberrations of rays, diftinguilhed by their different caufcs ; one arifing from the figure of the glafs or fpcculum, the other from the unequal re- frangibility of the rays of light. This laft fpecies is fometimes called the Newtonian, from the name of its difcoverer. See Optics, n" 17. 136. 173. ABERYSWITH, a market-town of Cardigan- ftiire,in Wales, feated on the Ridal, near its conflu- ence with the Iftwith, where it falls into the fea.

ABGILLUS (John), furnamed Prefter John, was fon to a king of the Frifcii ; and, from the aufterity of his life, obtained the name oi Preftcr, or Pricft. . He attended Charlemagne in his expedition to the Holy Land ; but inftead of returning with that monarch to Europe, it is pretended that he gained mighty con- quells, and founded the cmjiire of the AbylTines, call- ed, from his name, the empire of Prefter John. He is faid to have written the hiftory of Charlemagne's jour- ney into the Holy Land, and of his own into the In- dies ; but they are more probably trifling romances, written in the ages of ignorance. ABIANS, anciently a people of Thrace, or (accord- ing to fonicauthors) of Scythia. Tiiey had no fixed ha- bitations; they led a wandering life. Their houfes were waggons, which carried ail their poifellions. They lived on the llefli of their herds and flocks, on milk, and cheefe, chiefly on that of mare's milk. They were unacquainted with commerce. They only exchanged conur.oditics with their neighbours. They poll'elled lands, but they did not cultivate them. Thcyaflign- ed their agriculture to any w'ho Mould undertake it, re- ferving only to themfclves a tribute ; which they ex- afted, not w ith a view to live in aiRuence, but merely to enjoy the ncccffariesof lif'e. They never took arms but to oblige thofc to nuike good a promifc 10 them by wiiom it had been broken. They paid tribute to none of the neighbouring ftatcs. They deemed themftlves exempt from fuch an inipolition ; for they relied on their ftrength and courage, and coiifequently thought themfelves able to repel any invafion.

The flreets, which are well paved, centre in a fpacious area, in which tlie market is held ; and in the centre of this area is the market-houfe, which is fupported on lofty pillars, with a large hall of free-done above, in w hich the fummer- alhzes for the county arc held, and other public buli- ncfs done, the Lent aflizes being held at Reading. It has two churches ; one dedicated to St Nicholas, and the other to St Helena : the latter is adorned with a fpire, and both are faid to have been erected by the abbots of Abingdon. Here arc alfo two hofpitals, one for fix, and the other for thirteen poor men, and as many poor women ; a free fchool ; and a charity- fchool. The town was incorporated by (^uecn Mary. It fends two members to parliament, who are choftn by the inhabitants at large not receiving alms. Its great manufadure is malt, large quantities ofvvhichare fent by water to London. It is fix miles and a half foiith of Oxford, 47 eaft of Glouceiler, and 55 weft of London. This town is fuppofed by Bilhop Gibfoii to be the place called, in the Saxon annals, Clo-jcjhoo, where two fynods are faid to have been held, one in 742, and the other in 822. Long. 1. 20. Lat. ji.

ABIPONIANS, a tribe of American Indians, who formerly inhabited the diftrict oi Chak> in Paraguay; Alilphnm- but the hoiliiities of the Spaniards have now obliocd »u» them to remove fouthward intothe territory lying be- ll . tween Santa Fc and St Jago. The only account we ^''J"^*""" - have of them is that publilhed by M. DobrizhofFcr in 1785. Thisgentleman, wholived feven years in their country, informs us that they arc not numerous, the whole nation not much exceeding 5000 ; for which he aliigns as a reafon an unnatural cullom among their women of fometimes dcllroying their own children from motivesofjealoufy, left their hulhandsfliould take otlier mates during the long time they give fuck, which is not Icfs than two years. They are naturally white, but, by cxpofurc to the air and fmokc, become of a brown colour. They arc a ftrongand hardy race of people ; which our auiiior attributes to their marrying io late, an Abi|)onian fcldom or never thinking of mar- riage till 30 years of age. They are greatly celebrated on account of their chaltity and other virtues; though, according to our author, they have no knowledge of a Deity. They make frequent incurfions into the terri- tories of the Spaniards, mounted on the horfes which run wild in thofe parts. They have a kind of order of chivalry for their warriors ; and are fo formidable, that ] 00 of their enemies will riy before ten of thefc horfe- mcn. The hatred which thefc favages, whofe manners, though xnAc and uncultivated, arc in many refpccl» pure and virtuous, bear to the Spaniards, is invincible. " Thefc pretended Chriftians," fays our author," who are the fcura of the Spanifli nation, practice every kind of fraud and villainy among thefc poor barbarians ; and their corrupt and vicious morals arc fo adapted to pre- judice the Abiponians againft the Chriftian religion, that the Jefuit milHonaries have, by a feverc law, pro- hibited any Spaniard from coming, without a formal pennillion, into any of their colonies." — From his ac- count of the fuccels of thejefuits in converting them to Chriftianity, however, it does not appear that they have been able to do more than bribe them to a com- pliance with the ceremonicsof the Popilh fupcrftitions; fo that in general they are quite ignorant and uncivil- ized : a moll ilriking inftance of which is, that in counting they can go no farther than three; and all the art of the Jefuits to teach them the fimpleft nfc and cxpreflion of numbers has proved unfuccefsful. ABIRAM, a feditious Lcvite, who, in concert with Korah and Dathan, rebelled againft Mofes and Aaron, in order to fliare with them in the government of tiie people ; when Mofes ordering them to come V. ith their ccnfers bcl'ore the altar of the Lord, the earth fuddcnly opened under tlieir feet, and fwallowcd up them and their tents ; and at the fame inftant fire came from heaven, and confumed 250 of their follow- ers. ^^llmb. xvi.

Prifciaa aUb calU it the eijmparative cafe ; as fervin|T, among the Latins, for comparing, as well as taking away. T!ie ABLATIVE isoppolite to the DATIVE ; thefirll cxpreinng the aciion of taking away, and the latter that of giving. In Englilh, French, &c. there is no precifc mark xsliereby to dillingnith the ablative from other cafes; and we only ule the term in analogy to the Latin. Thus, in the two p]irafcs,M.' viagnitudt of the city, and he /poke Much of the city ; we fay, that of the city in the Jirlb \% genitive, and in the \^\.\.tx abiativ: ; becaufc it would be fo, if the two phrafcs were exprc lied in Latin. Tiiequellion concerning the Greek ablative has been the fubjec^ of a famous literary war between two great grasnmarians, Prifchlin and Crufms ; the former of whom maintained, and the latter oppofcd the reality of it. The difpute ftill fnbfifts among their refpedive followers. The chief rcafon alledged by the former is, that the Roman writers often joinedGrcck words with the Latin prepofuions, which govern ablative cafes, as well as with nouns of the fame cafe. To w hich their opponents anfwer, that the Latins anciently had no ablative thenifclvcs ; butinflcad thereof, made ufe, like the Greeks, of the dative cafe ; till at length they for- med an ablative, governed by prepofuions, which were not put before the dative : that, at firft, the two cafes had always the fame termination, as they flill have in many inrtances : but that this was afterwards changed in certain words. It is no wonder then, that the La- tins fometimcsjoin prepofuions which govern an abla- tive cafe, or nouns in the ablative cafe, with Greek da- lives, fincethey were originally the fame ; and that the Greek dative has the fame efFeft as the Latin ablative. ABLE, or abel (Thomas), chaplain to queen Ca- tharine confort to Henry the eighth, diftinguilhed him- felfby hi: zeal in oppofingthe proceedingsagainft that unfortunate princcfs for a divorce.

ABORIGINES, (Di.myfiusofHaricarnairjs,Livy, Virgil) ; originally a proper name, {;ivcn to a certain people in Italy, who inhabited the ancient Laiiuni, or country now called Campagtia tit Roiua. In this fenfe the Aborigines are diAinguiQied from the Jaiii- gcnse, who, according to the filfe Berofus, inhabited the country before iJiem ; from the Siculi, whom they expelled ; from the Grecians, from whom tiicy defcended ; J'rom the Laiir.s, whofe name they af- fumed after their union w iih itneas and the Trojans ; lallly, from the Aufonii, Volfci, Ocnotrii, &c. neigh- bouring nations inothcr parts of the country. %\htncc this people came by the appellation, is much difputed. St Jerom fays, they were fo called, as being, abfqiu engine, die primitive planters of the country after the flood : Dion, of HalicarnalFus accounts for the name, asdenotingthem the foundersof thcraccofinhabitants of that country : others think ihem fo called, as bcin^; originally Arcadians, who claimed to be earth-born, and not defcended from any people. Aurelius Vi.lor fuggefls another opinion, viz. that they were called Aborigines, q. d. Abirrigii:es, from ab " from," and er- rare " towandcr ;" as having been beforeawandering pcop'e. Paufanias rather thinks they were thus call- ed «T« ofiti, from " mountains ;" which opinion feems confirmed by Virgil, \\ ho, fpeaking of Saturn, tbelc- gillator of this people, fays, Isgiiius iiidociii ac di/pirfum marJibui altis Confofuit, Ugtfqut dfdit The Aborigines were either theoriginalinhabitantsof the country, fettled there by Janus, as fome imagine ; or by Saturn, or Cham, as others : not long after the difpcrlion, or even, as fome think, before it : Or they were a colony fcnt from fome other nation ; who cx- pcllingthcancient inhabitants thcSiculi,fetded in their place. — About this mother-nation there is great dif- pute. Some maintain it to be the Arcadians, parties of whom were brought into Italy at different times ; the firrt under the conduft of Oenotrius, fon of Lycaon, 45oyears before the Trojan war ; afccondfrom Thcf- f.ily ; a tliird under Evandcr, 60 years before the Trojan war : belides another under Hercules ; and another of Lacedx'mouians, who .ied from the fcverc difcipline of Lycurgus : all ihefe uniting, arc faid to have formed the nation or kingdom of the Aborigines. Other? will have them of barbarous rathe- than Gre- cian origin, and to have come from Scythia ; others from Gaul. Lallly, others will have them to be Ca- naauites, expelled by Jolhua. Tkc ABO [ 22 ] A B R Abortion I . Aboukir. The term //i^£/;/j;;«.-/, though fo famous in antiquity, is ufej in modern gcogiajihy only occalioiially as an appellative. It is given to the primitive inhabitants of a country, in coutraJidinction to colonics, or new races of people. ABORTION, in midwifery, the exclufion of a foe- tus before it has acquired a fufficient degree ot perfec- tion to enable it to perform refpiration and the other vital functions. See Midwikerv. The pradice of procuring abortions was prohibited by the ancient Greek legillators Solon and Lycurgus. Whether or not it was permitted among the Romans, has been much difputed. It is certain the pradtice, which was by them called vifcenhns vim iiiferre, wa,s frequent enough : but whether there was any penalty on it, before the emperors Scverns and Antonine, is thequcftion. Noodt maintains the negative ; and fur- ther, that thofe princes only made it criminal in one particular cafe, viz. of a married woman's pradillng it out of rcfentment againll her hufband, in order to defraud him of the comfort of children : this was or- dered to be punillied by a temporary exile. The foun- dation on whicii the praftice is faid to have been al- lowed, was, that the fuctus, while in utcro, was repu- ted as a part of the mother, ranked as one of her own vifcera, over which Ihc had the fame poweras over the refl : befidcs, that it was not reputed as a man, howo ,- nor to be alive, otherwife than as a vegetable ; confe- quently, that the crime amounted to little more than that of plucking unripe fruit from thetrce. Seneca rc- prcfents it as a peculiar glory of Htlvia, that Ihe had never, like other women, whofe chief iludy is their beauty and ihape, dcllroyed the foetus in her womb. The primitive fathers, Athenagoras, TertulHan, Mi- nutius Ftlix, AugulUn, &c. declaimed loudly againfl the pra^ice as virtual murder. Several councils liavc condemr.id it. Yet we are told that the modern Ro- niifh •ertleliallical laws allow of difpefations for it. Egane mentions the rales at which a difpenfaiion for it may be had. The praclice of artificial abortion is chiefly in the hands of women and nurfes, rarely in that of phyfi- cians ; who, in fome countries, are not admitted to the prrfeHiou without abjuring it. Hippocrates, in the oath he would have enjoined on all phyiicians, includes their not giving the pcffm aborirous ; though elfe- wherc he gives the formal procefs v.hereby he him- felf procured in a young woman a mifcarriagc. It may, however, be obfervcd, that often all the powers of art prove inefFeftual, and no Icfs often do the at- tempts prove the means of punilhment by the fatal confequences which they produce.

ABRABANEL, Abarbanel, or Avravan'el, (Ifaac),acelcbratcdrabbi, defeendcdfrom king David, and born at Lilbon A. D. 14^7. He became eoun- fellor to Alphonfo V. king of Portugal, and afterwards to Ferdinand the Catholic ; but in 1492 was obliged toleave Spain with the other Jews. In Ihort, after re- fiding at Naples, Corfu, and feveral other cities, he died at Venice in i Jo3, aged 71. Abrabanel palfed for one of the moll learned of the rabbis; and the Jews gave him the na]nes of the Sage, the Prince, and the Great Politician. We have a commentary of his on all the Old Teftament, which ispretty fcarce: he tlierc principally adheres to the literal fenfe ; andhisflile is clear, but a little ditFufe. His other works are, A Trca- tifeon the Creation of the World; in which he refutes Arillotlc, who imagined that the world was eternal ; A Trcatife on the explication of the prophecies relating to the Meffiah, againlf the Chrillian : A book con- cerning articles ef Kaith ; and fome others Icfs fought after. Though Abrabanel difcovers his implacable a- vcriion to Chrillianity in all hiswriiings, yet he treat- ed Chriftians with politenefs and good-manners in the common affairs of life. ABRACADABRA, a magical word, recommended by Serenus Samonicus as an antidote againft agues and feveralothcr difcafes.

It would be of little ufc to dwell long upon thefc par- ticulars, fmcc they arc fo well known. But tradition has fupplied numbcrlcfs others, the mention of one or two of which may not be unacceptable. ^lany extraordinary particulars have been told rela- ting to his convcriioii from idolatry. It is a pretty general opinion, that he fucked in the poifon with his milk ; that- iiis failicr made ftatues, and taught that they were to be worfiuppcd as gods*. Some Jewilh authors relatcf , that Abra'iam followed the fame trade withTcrah foraconliderable lime. Mainionaidcsjfays, that he was bred up in the religion of tiie Saba;ans, who acknowledged no deity but the flars ; that his reflec- tions on the nature of the planets, his a.imiration of their motions, beauty, and order, made him conclude there mull be a being fuperior to the machine ot the univerfe, a being who created and governed it : how- ever, according to an old tradition, he did not renounce paganifm till the 5o"'yearof hisage. It isrclated\\, that his father being gone a journey, left him to fell the flatucs in his abfence ; and that a man, who pre- tended to be a pnrchal'er, alked him how old he was, Abraliam anfwered, "Fifty." — "Wretch that thou art, (fjid the other), for adoring at fuch an age, a be- ing which is but a (lay old .'" Thefc words greatly confounded Abraham. Some time afterwards, a wo- man brought him fome flour, that he might give it as an otFering to the idols; but Abraham, inrtead of do- ing fo, took up a hatchet and broke them all to pieces, excepting the largell, into the hand of which he put the weapon. Terah, at his return, aftced whence eamc all this havock ? .Abraham made anfwcr that the ftataes had had a great contcfl which (hould eat riril of the oblation ; " Upon which (faid he), the god yon fee there, being the ftouteli, hev.cd theoihers to pieces with thai hatchet." Terah told him this was bintcr- iug ; for thole idols had not the fenfc to aA in this manner. Abraham retorted thefe words upon his fa- ther againft the worlhipping of fuch gods. Terah, ftung with his raillery, delivered up his fon to the cognifancc of Nimrod, the fovereign of the country : who exhorted Abraham to worlhip the lire ; and, upon his refufal, commanded him to be thrown into the midll of the Hanies : "Now let your God (laid he) come and deliver you :" But (adds the tradition), Abra- _ ,. ham came fafe and found out of the flames. — This Helirilcla f^'^itio" is not of modern date, lince it is told by St (•ciicHu.

Perhaps the am- biguity of the word Ur" might have given rife to the iiction altogether. Such as lay Ilrefs on the following words which God fays to Abraham (Gen. xv. 7.), / aw the Lord that broi^ht thee out oj Vr oj tht Chatdeei, imagine that he faved him from a great perfccution, fincc he employed the very fame words in the begin- ning of the decalogue to denote the deliverance from Egypt. Abraham is faid to have been well (killed in many feienees, and to have wrote feveral books. Jofcphus-j- tells us that he taught the Egyptians arithmetic and geometry ; and, according to Eupolcmus and Ariapan, he inllruoled the Pha'nicians, asw'ellas the Egyptians, in adronomy. A work which treats of the creation has been long aferibed to him ; it is mentioned in the Talnuid:]:, and the Rabbis Chanina, and Hofchia ufed to read it on the eve before the fabbath. Ih the firft ages of Chriflimity, according to St Epiphanius \, a heretical feci, called Sclhinians,difpcrfed a pieccwhich had the iwXtoi ylbraham' i Rtvciation. Origcn mentions alio a treatifc fuppofed to be wrote by this patriarch. All the feveral works which Abraham compofcd in the plains of Mamre,are faid to be contained in the library of the monaflcry of the Holy Crofs on Mount Anu- ria, of Ethiopia *{ . The book on the creation was printed at Paris 1552, and tranllated into Latin by Poilcl : Riltangel, a converted Jew, and profelfor at Konigfberg, gave alfo a Latin irandation of it, with remarks, in 1642.

ABRAXAS, an antique Hone with the word abraxas engraven on it. They are of various fizes, and moll of them as old asthc third century. They arc frequent in the cabinets of the curious ; and a colledionofthcm, as complete as poUible, has been defired by ieveral. There is a lineone in theabbcy of St Genevieve, which lias occalioncd much Ipeculation.

The graving is rarely good, but the word on the revcrfe is ibmetiincs faid to be in 3 more modern taflc than the other.

It is difpuled whether tlie Veronica of M(>nt;euil, or the graniie obcliik men- tioned by Gori, be Abraxaja. ABREAST ( a fca-term), (ide by lide, or oppofite to ; a fituation in which two or more fliips lie, with their flies parallel to each other, and their heads equal- ly advanced. This term more particularly regards the line of battle at fea, where, on different occafions of attack, retreat, or purfuit, the fever.1l fquadrons or divilions of a fleet are obliged to vary their difpofiiions, and yetmaintain aproper regularity by failing in right or curved lines. When the line is 'i .-.-mt A abrt a j\ ,x.\\t whole Iquadron advances uniformly, the fliips being equally diltant from and parallel to each other, fo that the length of each fiiip forms a right angle with ihc extent of the fquadron or line abreaft.

ABRIDGEMENT, in liieratkire, a term lignify- ing the rcduclion of a book into a fmallcr cor.ipafs. The art of conveying much feniinicnt in few words, is the happiefl; talent an author can be pofleired of. 'J'liis talent is peculiarly ncceliary in the prcfent flatc of literature ; I'or many writers have acquired the dex- terity of fprcading a few triiical thoughts over Ieveral hundred pages. M'hcn an author hits upon a thought that plcafcs him, he is apt to dwell upon it, to view it in diti'erent lights, to force it in improperly, or upon the llightcfl relations. Thougli this may be pleafant to the writers, it tires and vexes tlic reader. 'Ihcre is another great fourcc of difluiion in compolition. It is a capital objcft with an author, whatever be the fub- jert, to give vent to all his bcfl thoughts. When he finds a proper place for any of them, he is peculiarly happy. But, rather than facrifice a thought he is fond of, he forces it in by way of digreffion, or fuperfluous illuflration. If none of thefe expedients anfwer his purpofe, he has recourfe to the margin, a very conve- nient apartment for all manner of pedantry and imper- tinence. There is not an author, however correft, but is more or lefs faulty in this refpei^. An abridger, however, is not fubject to ihcfe temptations. The thoughts are not his own ; he views them in a cooler and lefs atledionaie manner ; he difcovcrs an impro- priety in fome, a vanity in others, and a want of utili- ty in many. His butlnefs, therefore, is to retrench fu- perfiuitics, digreffions, quotations, pedantry, &c. and to lay before the public only what is really ufcful. This is by no means an eafy employment : To abridge fome books, requires talerits equal, if not fuperior, to tliofe of the author. The facts, manner, fpiiit, and reafoning, muflbcprcferved ; nothing efleniial, either in argument or illuflration ought to be omitted. The dilHculty of the tafk is the principal reafon why we have fo few good abridgements : Wynne's abridgment of Locke's Ellay onthcKumauUndcrflanding, is, per- haps, the only unexceptionable one in our language. Thefe obfervaiions relate folely to fuch abridge- ments as are dellgncd for the public. But, When a perfon wants to fet down the fubflanceof any book, a (liortcr and lefs laborious method may be followed. It would be foreign to our plan to give ex- amples of abridgements for the public : But as it may be ufeful, efpccially to young people, to know how to abridge books for their own ufe after giving a few di- reolions, we Ihall exhibit an example or two, or fliow with what cafe it may be done. Read the book carefully ; endeavour to learn tlie principal view of the author, attend to the arguments employed : When you have done fo, you will general- ly find, that what the author ufes as new or additional arguments, are in reality only collateral ones, or cx- tenfions of the principal argument. Take a piece of paper A B R [ 25 ] A B K Abridge- paper or a common-place book, put down what the nunt. author wants to prove, fiibjoin the argument or argu- ^~"^' meiits, and you have the lubftance ot" the book in a few lines, tor example, In the EU'ay on Aiiracles, Mr Hume's defign is to prove. That miracles which have not been the imme- diate objects of our fcnfes, cannot reafonably be be- lieved upon the tcdimony of others. Now, his argument (for there happens to be but one) is, " That experience, which in fomc things is variable, " in others uniforn\, is our uidy guide in reafoning " concerning matters of li.t\. A variable experience " gives rife to probability only ; an uniform cxpcri- *' ence amounts to a proof. Our belief of any fac't " from the tellimony of cye-witnell'cs is derived from . " no other principle than our experience in the vcra- *' city of human teftimony. If the faifl attcfled be " miraculous, here arifes a conteil of two oppofite cx- " periences, or proof againft proof. Now, a miracle " is a violation of the laws of nature ; and as a firm and " unalterable experience lias eftablilhcd thefe laws, the *' proof againll a miracle, from the very nature of the " faft, is as complete as any argument from experi- " ence can poflibly be imagined ; and if fo, it is an un- " deniable tonfcqucnce,thatit cannot be furmountedby " any proof whatever derived from human teilimony." In Dr Campbell's DilTertation on Miracles, the au- thor's principal aim is toflicw thefallacy of Mr Hume's argument ; which he has done mofl fuccefsfuUy by another fingle argument, as follows: " The evidence arifingfrom human teRimony ;/7;o/ " foltly derived from experience : on the contrary, te- «' flimony hath a natural influence on belief antcce- " dent to experience. The early and unlimited alfent •' given to teftiniony by children gradually contrads " as they advance in life : it is, therefore, more ron- " fonant to truth, to fay, that our diffidcnc: in tertimo- " ny is the refult of experience, than that aar fuith in " it has this foundation. Bcfides, the uniformity of " experience, in favour of any faft, is not a proof a- " gainft its being reverfcd in a particular inllance. " The evidence arifing from the linglc tcflimony of a " man of known veracity will go farther to cllablilh a " belief in its being ailiially rcverfed : If his tellimo- " ny be contirmed by a few others of the fame charac- " tcr, we cannot with-hold our alfent to the truth of it. " Now, though the operations of nature are governed " by uniform laws, and though we have not the tcfti- " mony of our fenfcs in favour of any violation of " them ; ftill, if in particular inflances wc have the " tcflimony oi thou fundi of our fellow-creatures, and " thofe too, men of ftri t integrity, fwaye d by no mo- " tivcs of ambition or intireft, and governed by the " principles of comnion-fcnfe, That they wereaiftu- " ally eye witnelfes of thefe violations, the conflitu- " tion of our nature obliges us to believe them." Thefe two examples contain the fuijftance of about 400 pages. Making private abridgements of this kind has many advantages ; it engages us to read with .■jccuracy and attention ; it fixes the fubjeit in our minds ; and, if wc ihould happen to forget, inflead of reading the book r._';ain by glancing a few lines wc are not only in poirelRouof the chief arguments, but rc- calin a good mcafurc tUc author's method aad mauner.

Thefe you may afterwards extend in the form of a dif- courfe drelfed in your own language.

ABRINCATARUM oppidum (anc. geog.), tlir town of the Abrincatx or Abrincatui, now Avranchti, in France, fituatcd on an eminence in the fouth-wcft of Normandy near the borders of Brittany on the Er.c- lilh channel. W. Long, i. 10. N. Lat. 4S. 40I ABROGATION, the acl of abolilhing a law, by authority of the maker ; in which fenfc the word is fynonymous with abolition, repealing, and revocation. Abrogation ftands oppofcd to rogation : it is dillin- guilhed from dirr0gation,wh'\ch impliesthetakingaway only fomc part of a law ; t'rom fulrogation , ody fcparately, which they call a tine, omitting the conli- deration of its breadth and thicknefs. Thirdly, It is by abftraction that the mind forms general or univcrfal ideas ; omitting the modes and relations of the parti- cular objcits whence they arc formed. Thus, when we Ihould underAand a thinking being in general, wc gather from ourfclf-confcioufnefs what it is to think ; and, omitting thofe things which have a particular re- lation to our own minds, or to the human mind, we conceive a thinking being in general. Ideas formed in this manner, which are what we properly aWakjirad ideai, become general reprefen- tatives of all objects of the fane kind ; and their names applicable to whatever exifts conformable to fuch ideas. Thus the idea of colour that wc receive from chalk, fnow, milk, &c. is a rcprefentativeofall of that kind; and has a name given it, 'd)l;ilen:/s, \\hich fignifies the fame quality wherever fuujid or imagi- ned. ABSTRUSE, fomething deep, hidden, concealed, or far removed from common apprehculions, and there- fore not eafily underftood ; in oppofiiion to what is obvious and palpable. Thas metaphyfics is an ab- flrufc fcicncc ; and the doiflrine effluxions, and the method flV maximis et muiiniis, arc abftrufc points of knowledge. ABSURD, an epithet applied to any thing that oppofcs the human apprchention and contradicts a manifclt truth. Thus, it would be abfurd 'o fay that 6 and 6 make only 10, or to deny that twice 6 make 12. Whenthc terra able folidity of the edifice, the huge malles which com- pofe it, the hieroglyphics it is loaded with, (lamp it a work of the ancient Egyptians. Beyond it is a temple 300 feet long and 14J wide. Upon entering the mo- nument wc meet with an immenfe hall, the roof of which is fupported by 28 columns 60 feet high and 19 incircumference at the bafe. They are i2fcetdiHant from each other. The enormous ilones that form the ceiling, perfectly joined and incruiled, as it were, one in the other, offer to the eye nothing but one folid plat- form of marble 1 16 feetlongand 26 wide. The walls are covered with hieroglyphics. One fees there a mul- titude of animals, birds, and human figures with point- ed caps on their heads, and a piece of fluff hanging down behind, drelTcd in loofe robes that came down only to the waift. The fculpture, however, is elumfy ; the forms of the body, the attitudes and proportions of the members, illobferved. Amongfl thcfe we may di- ftinguifli fome women fuckling their children, and men prefenting offerings to tliem. Here alio we meet with the divinities of India. Monfieur Chevalier, formerly governor of Chandcrnagore, who relided 20 years in that country, carefully vilitcd this monument on his re- turn from Bengal. He remarked here the gods Jag- gnnat, Coiuz, and Vcchiiou or Wijhion, fuch as they arc reprefcnted in the temples of Indoflan. — A great gate opens at the bottom of the lirll hall, wjiich leads to an apartment 46 feet long by 22 wide. Six fquare pillars fupport theroof of it ; and at the angles are the doors of lour other chambers, but fo clioaked up m ith rub- biili that they cannot now be entered. The lafl hall, 64 feet long by 24 wide, has flairs by which one dc- fcends into the fubterrancous apartments of tiiis grand cdiiice. The Arabas,in fearching after treafure, have piled A B Y C 3t ] A li Y Aliydos piled up heaps of earth and rubbilh. In the part we- ll are able to penetrate, fciilpture and hieroglyphics arc Aliyfs. difcoverable as in the upper llory. The natives lay liiat '^ they corrcfi-oiid exactly with tiiofc above ground, and thai the columns are as deep in the earth as they are loity above ground. It would be dangerous to j>(( tar into thole vault ; for the air of them is lb loaded with a niephitic vapour, that a candle can fcarcc be kept burn- ing in them. Six lions heads, placed on the two lides of the temple, fervc as fpouis to carry off the water. You mount to the top by a flaircafe of a very lingular llruchirc. It is built with floues incrufted in the wall, and projecting lix feet out ; fo that being fupported on- ly at one end, they appear to be fufpendeil in the air. The Walls, the roof, and the columns of this cditiee, have futi'ered nothing from the injuries of time ; and (lid not the hieroglyphic:, by being corroded in fome places, mark its antiquity, it would appear to have been newly built. The lolidity is fuch, that unlcfs peojde make a point of dcllroying it, the building niu(t lall a great number of ages. Except the colollal ligurco, whofehc.idsferve as an ornament to the capitals of the columns, and which- are fculpturcd /« relievo, the relt of the hieroglyphics which cover the inlide are carved in Ito.ic. To the left of this great building we meet with another much fmaller, at the bottom of which is a fort of altar. This was probably the fancluary of the temple of Ofiris. ABYLA, (Ptolemy, Mela) ; one of Hercules's pil- lars on the African lide, called by the Spani.irds Sur- ra de Ins iMoiias, over againll Calpc in Spain, the other pillar ; fuppofcd to have been formerly joined, butfe- paratcd by Hercules, and thus to have given entrance to the lea now called the IMcditerraiiean : the lin)its of the labours of Hercules, (Pliuy.) ABYSS, in a general fenfe, denotes fomcthing pro- found, ant), as it v;ere, bottomlefs. The word is ori- ginally Greek, afi-5-3-oc; compounded of the prinntivc a, and Ci^ra-n, q. d. without a bottom. Abyss, in a more particular fenfe, dcnots a deep mafs or fund of waters. In this fenfe, the word is particularly ufcd, in the Septuagint, for the water which God created at the beginning with the earth, which encompatred it round, and which our iranlla- tors render by def/>. Thus it is that darknefs isl'aid to be upon the face of the abyfs. Abyss is alfo ufed for an immcnfe cavern in the earth, wherein God is fuppofed to have coUefled all thofe waters on the third day ; which, in ourveriion, is rendered thc/eai, and elfewhere ihc great deep. Dr Woodward, in his Natural Hillory of the Karth, af- fcrts, That there is a mighty colledion of waters in- ciofcd in tlie bowels of the earth, conllituting a huge orb in the interior or central parts of it ; and over the furfaceof this water he fuppofes the terreftrial ftrata to be expanded. This, according to him, is what Mofes csilh the great deep, and what moft authors render the great abyfs. The water of this vaft abyfs, he alleges, does communicate with that of the ocean, by means of certain hiatufes or ehafms palling betwixt it and the bottom of the ocean : and this and the abyfs he fup- poies to have one common centre, around which the water of both is placed ; but fo, that the ordinary fur- face of the abyfs is not level with that of the ocean, nor at fo great a diltaucc from the centre as the other. it being for the moft part rcflraincd and deprefled by the ftrata of earth lying upon it ; but whenever thofe ftrata are broken, or fo lax and porous that water can pervade them, there the water of the abyfs afccnds : lills up all the clefts and tiifures into which it can get admittance ; and faturatcs all the intcrflices and pores of the earth, ftone, or other matter all around the globe, quite up to the level of the ocean. The exiftcncc of an abyfs or receptacle of fub- terraneous waters, is controverted by Camcrarius*; and defended by Dr Woodward chieriy by two ar- guments : the tiril drawn from the vaft quantity of water which covered the earth in the time of the deluge ; the fccoiid, from the conlideraiion of earthquakes, which he endeavours to Ihow are oc- calioncd by the violence of the waters in this a- byfs. A great part of the tcrrcllrial globe has been frequently Ihaken at the fame moment ; which argues, according to him, that the waters, which wcrt tile occalion thereof, were co-extended with that part of the globe. There are even inftanccs of univcrfal earthquakes ; which (fays he) ftiow, that the whole abyfs muft have been agitated : for lo general an effect mull have been produced by as a general caufe, and that caufe can be nothing but the fubtcrraneous abyfsf. To this abyfs alfo has been attributed the origin of fprings and rivers ; the level maintained in the furfaceof different feas ; *nd their not overflowing their banks. To the cffluvias emitted from it, fome even attribute all thcdiverlitiesof weather and change «i our atmofphercj. Kay* , and other authors, an- cient as well as modern, fuppofe a communication be- tween the Cafpian fea and tlie ocean by means of a fubterrancan abyfs : and to this they attribute it that the Cafpian fta does not overriow,notwithftanding the great number of large rivers it receives, of which Kempfer reckons above Jo in the compafsof 6omiles; tho', as to this, others fuppofe tliat the daily evapo- ration may fufSce to keep the level. The different arguments concerning thi^ fnbjcft may be feen collecHcd and amplitied in Ccckburu's Inquiry into the Truth and Cirtai,:ty cf the Ah- faic Delude, p. 271, &c. After all,'howevcr, this amazing theory of a central abyfs is far from be- ing demonftrated : it will perhaps in fevcral rcfpefls appear inconliftent with found philofophy, as well as repugnant to the phenomena of nature. In particular, if we believe any thing like eleflric attradion to have prevailed in the formation of the earth, we muft believe that the fcparatioii of the chaos proceeded from the union of limilar particles. It is certain that reft is fa- vourable to fuch operations of nature. As, therefore, the central parts of the earth were more immediately quicfcent than thofe remote from the centre, it fc unsab- furd to fuppofe that the heavier and dcnfer bodies gave place to the more light and fluid ; that the central part ftiould conlill of water only, and the more fuperticial part of a cruft or ihell.

ABYSSINIA, by fomc called Highif Ethiopia, and by the Arabians Al Habujh, is bounded on the north by Nubia; on the eall,by ilie Arabicgulph or Red Sea, and the kingdom of Adel ; on the fouth, by the king- doms of Ajan, Alabo, and Gingiro ; and on the well, by the kingdomsof Goram, and par: of Gingiro ; and is divided into a great number of provinces. The principal river is the Nile, which has its fourcein this country ; and the mofl confulerablelakc, that of Dam- bea, which difchar£^cs itfelf intothe Nile, is about 700 miles in Icngih, and 90 in breadth. The air is pretty temperate inthe mountains, and therefore thcirtowns and ftrong holds arc generally placed on them ; but in the valleys it is hot and fulFocating. The foil and face of the country is various. Jn fome places there arc nothing but rocks and profound caverns : in others, efpecially where thcrcarerivcrs,tlie lanuiscxceeding. ly fruitful ; and the banks of ihefe ilreams are bordered with flowers of various kinds, many of \\'hich are un- known in Europe. The torrents in the rainy, fcafon walh a great deal of gold from the mountains. This feafon begins in May, when the fun is vertical, or di- reftly over their heads, and ends in September. — The country produces a great variety of animals, both tame and wild.fuch as lions, tigers, rhinocerofcs, leopards, elephants, monkeys, flags, deer ; horfes, camels, dro- medaries, goats, cows, Iliecp ; likewife oltriches, with a vaft variety of other birds. In the rivers are croco- diles and the hippopotamuf . Travellers mention alfo a peculiar kind of bees, fmall, black, and without a iling, which hive in the earth, and mak'- honey and wax that arc extremely white. The country is great- ly infelled with loculls, which devour every thing that is green wherever they come. Theinhabitanisare Moors, Pagans, Jews, and Chri- flians. The lafl was the reigning and eflablilhed reli- gion wlien father Lobo vifited this country in 1624. This divcrfity of people and religion is the rcafon tjiat the kingdom, in JifFerent parts, is underdifferentforms of government, and that their laws and cuftoms arc ex- tremely various. Some of the people nrither fow their lands norimprove them ; but live on milk and tlelh.and encamp like the Arabs, without any fettled habita- tion. In fome places they prac^ife no rites ofworlhip, though they believe that there dwells in the rcj;ions a- bove a Being who governs the world : Ihisdeity they call'5.v/. Inthefc parts where Cluiftianily isprofed"ed,it isfo corrupted with fupcrflitious errors, and fo mingled vith certtnonics borrowed from the Jews, that little befide the mine of Chrillianity is to be found among them. (See the next article.) — They have two har- vefts intheye.tr ; one in winter.which begins in May, aaJ lafts, witli great rigour, through the mouths oi July, Augufl, and September; and the other in fpring. AbylTmin. Every man who has a thoufand cowsfavcsoncea-ycar ^ ' a day's milk, and makes a bath for his friends ; fo that to give an idea of a man's wealth, their common ex- prcllion is, hi bathes fo many timei a-year. Their males marry about ten years old, and their females younger. Their marriage tie isfoloofe, that they part whenever they tind that they cannot live agrcealjly together. Belldes the lirge towns, there are a great number of villages, which in for.ic places arc fo thick fowu, that they look like one continued town : the houfes arc very mean, being but one flory high, and built of flraw, earth, and lime. In mofl of the towns the houfes are feparated by hedges, which are always green, and mixed with flowers and fruit-trees at a cer- tain dillance from each other, whicliaflbrds an agree- able profpei;t. Tlic government is monarchical. The ^ fovcrcign has the title of Negus, and is an abfolutc prince. When he is in camp, the tents arc fo regularly difpofcd as to have the appearance of a city ; and there is a captain over every divilion, to prevent diforders, and to execute juflice. The Abyliines in general are of an olive complexion, tall, graceful, and well featured. Thofe who are nei- ther mechanics nor tradefmcn (which few of tliem are) nor tillers of the ground, are inured to bear arms,wliich are a head-piece, a buckler, a coat of mail, bows and arrows, darts, pikes capped with iron at both ends, a fling, and a fvvord : they have very few fire-arms, anil thofe were introduced by the Portuguefc. The habit of perfonsofquality is a fine lilken vert, or fine cotton, with a kind of fcarf. The citizens have the fame ha- bit, only coarfer. The common people have nothing but a pair of cotton drawers, and a fcarf which covers the relt of their body. The women are of a healthy conflitution, active, and moderately handfome, having neither flat nofes nor thick lips like the negroes ; and nature is fo friendly, that they Hand in little need of midwivcs, which isindecd thecafe, of moft countriesin the torrid zone. They appear in public as in Europe, without being forbid the convcrfation of the men as amongthe Mahometans. Princeffes of the royal blood are not permitted to marry foreigners : and when they take the air, they go in great flate, with 400 or 500 women attendants. Their language is the Ethiopic, which bears a great affinity with the Arabic ; but par- t'cular provinces have a different dialtft. Manu failures are almoft wholly wanting in this coun. try ; and the few trades which they have amongfl thein are always conveyed from the father to the children. They fecm indeed by their churches, and other ruinated places, to have had a knowledge of archite<5ture. But the workmen were fent for from other countries, and were forced to do all thcmfelves ; fo that xvhen thefc fabrics v.'cre reared, efpecially the imperial palace built by Peter Pais,a Portuguefc architcfl:, the pcopleflock- cd from all parts of Ethiopia to view it, and admired it as a nev/ wonder of the world. — Gold, lilvcr, copper, and iron, are the principal ores with which their mines abound in this extenfive part of Africa: but not above one third part is made ufe of by way of merchandize, or converted into money, ofwhi'-h they have litt'eor no ufe in Abylllnia. They cut their goM indeed into fmall pieces for the pay of their troops, and for expen- /es of the court, which is bat a modern cuiloni among them ; A B Y [ 33 ] A B Y AHyflinla. tlicm ; ihcking's gold, before the end of ihc 1 7ih ccii- ' " ' tury, being Ijid up in his trcafiiry in ingois, with in- tent to be never carried out, or never iifcd in any thing but velFels and trinkets for the fervicc of the palace. In the lieu of fmall money, they make ufc of rock fait as white as fnow and as hard as Hone. This is taken out of the mountain of Lafta, and put into the king's warehoufes ; where it is reduced into tablets of a foot long, and three inches broad, ten of which are worth about a French crown. When they are circulated in trade, they are reduced into ftill fniallcr pieces, as oc- cafion requires. This fait is alfo applied to the fame pnrpofe as common fca-falt. With this mineral fait they purchafe pepper, fpices, and iilk fluff's, which arc brought to them by the Indians, in their ports in the Red Sea. Cardaraunis, ginger, aloes, myrrh, caflia, civet, ebony-wood, ivory, wax, honey, cotton and li- nens of various forts and colours, arc merchandizes wliich may be had from AbylFinia ; to whicii may be added fugar, hemp, flax, and excellent wines, if thcfe people had the art of preparing them. It is affirmed there arc in this country the fincll emeralds that are any where to be found ; and, though they are found but in one place, they arc there in great quantities, and fomc fo large and fo perfeft as to be of almoft in- I cflimablc value. The greatefl part of the nierchan- difes abovemcntioncd, are more for foreign than in- land irade. Their domellic commerce confifts chiefly in fait, honey, buck-wheat, grey peafe, citrons, oran- ges, lemons, and other provifions, with fruits and her- bage neceflary for the fupport of life, Thofe places that the Abyflian merchants frequent the mofl, who dare venture to carry their commodities by fea them- felves, are Arabia Felix, and the Indies, particular- ly Goa, Cambaye, Bengal, and Sumatra. With regard to their ports on the Red Sea, to which foreign mer- chants commonly refort, the moft conlldcrable are thofe of Mette, Azum, Zajalla, Maja, Dazo, Patea, and Brava. The trade of the Abyflinians by land is inconfiderable. There are, however, bands of them who arrive yearly at Egypt, particularly at Cairo, la- den with gold dull, which they bring to barter for the merchandifes of that country, or of Europe, for which they have occafion. Thefe catilas or caravans, if we may be allowed thus to call a body of 40 or jo poor ■wretches who unite together for their mutual allift- ance in their journey, are commonly three or four months on their route, travcrfing forefls and monn- tainsalmoflimpaflabIe,in order to exchange their gold for neceflaries for their families.and return immediately with thegreateftpartofthemerchandifcontheirbacks. Frequently the Jews or Egyptians give them large credit ; which may feem/urprifing, as they are beyond recourfe if they fliould fail of payment. But experience has fliown, that they have never abufed the confldencc rcpofed in them ; and even in the event of death, their fellow-travellers take care of the cffcCls of the deceal- ed for the bcnelit of their families, but in the lirll place for the difcharge of thofe.debts contracted at Cairo. — It remains only to be obfervcd, that one of the prin- cipalbranchcs of trade of t!ie Abyllinesis thatof llaves; who arc greatly cfleenieJ in the Indies and Arabia for the bcft and moft faithful, of all that the other king- doms of Africa furnilh. The Indian and Arabian mer- chants frequently fublUtutc them as their fadors; and, Vol. I. on acconnt of their good fcrviccs and integrity,rot only AbyJIiuIa. often give them their libcrty,but liberally reward tliem. "^ Into this part of the globe the admiuoii of travel- lers has been fuppofed extremely diflicult, and their return from thence almoft impradicable. A Scotch gentleman, howe\er, of family and fortune, James Bruce, El'q; of Kinnaird, is known not only to have entered that country, but to have re fidcd in it fcveral years, ar.d returned fsfe home, bringing with him many great curiofities. Soon after his return, the fol- lowing notice was given by the Count dc Bufion in an advertifement prefixed to the ;d volume of Iiis Hiflo- ry of Birds : " A new aid which I have received, and which I am anxious to announce to the public, is the free and generous communication which 1 had of the drawings and obfervations of James Bruce, El'q; cf Kinnaird, who returning from Numidia, and the inte- rior parts of AbyfFinia, llopt in my houfe.for fcveral days, and made me a partaker of the knowledge which he had acquired in a tour no lefs fatiguing than ha- zardous. It filled me with the utmofc aHonifliment to view the numerous draw ings which he had made and coloured himfclf. He polTefl'es the mofl pcrfeft repre- fentations and defcriptions of the birds, filhes, plants, edifices, monuments, drefs, arms, &c. of different na- tions, all of them objcfls worthy of knowledge. No- thing has efcaped his curiofity, and his talents have been proportioned to it. The Englilli government will without doubt take proper meal^ures for the, pub- lication of his work. That refpeftable nation, which lias given a lead to all others in difcoveries of every kind, will not fail to add to its glory, by fpeedily com- municating to the world at large, thofe of this excel- lent traveller, who, not contented with accurate de- fcriptions of nature, has made many important obfer- vations on the culture of different kinds of grains ; oa the navigation of the Red Sea ; on the courfeofthe Nile, from its mouth to its fource, which he has been the firftto difcover ; and on different particulars which may be of the highefl utility to commerce and agri- culture, thofe great arts which arc but little known and ill cultivated. Yet, on thefe alone, the fuperiori- ty of one nation over another does depend, and for ever will depend." It is much to be regretted, that after fo long an in- terval, this gentleman's difcoveries have not yet made their appearance. The delay has given rife to various fpcculations. Doubts have even been entertained con- cerning the credibility of the reports that have tran- fpircd, or been gathered from his convcrfation. His honour and abilities, however, are too exteufively known tobeatfctfedbyfuch injuriousiiifinuations.That he hath great talents for the information of his read- ers, appears by his differt.uion on the Theban harp*, • Sm tht which Or Burncy hath infcrtcd in the firft volume of article his Iliffory of Mulic, and in which are alfo mentioned Harpid fcveral of the Abyliinian inftrumcnts. Mr Bruce more- ." * over, is faid to have a great facility in learning Ian- {Tuages, and talents for drawing ; nor perhaps was any other traveller furnillicd with folarge and fcientihcan apparatus of inftruments. Add to all this, that he is poUclTed of afpirit and entcrprife not calily to be e- quallcd. The fpeedy production, therefore, of foin- tercfting an account as he is capable of giving, of this almoft unfrequented part of Africa, cannot but ftill be E earncftly A B Y [ 3-1- ] A B Y Aliyfiliwa. earneftly wiihcd for. In the mean time, the following * '■ authentic anecdotes n ill not, it is prcfunicd, he imac- ccptable, nor apj ear foreign to the prel'ent article. Mr Bruce was appointed confiil to Algiers, where hccoiiiinucd till 1765. In Iiiiic 1764, he rcqueftcd leave of at Icucc from the fccrctary of flatc for the foiithern dcpartmcm, in order to make fomc drawings of 2nlic|iii!its near Tunis. In Mr Uriice's lart letter from Algiers to the fame fecrctary (dated December 29. 1764), he alludes to another leave of ablcnce, which he had likewifc re- queftcd, that he might vilit parts of the African con- tinent. He explains himlelf no farther in this letter ; hut it is believed that he proceeded confiderably to the fouthward of Algiers, and made thofe very capital drawings of remains of Roman architcfture, which many have fecn lincc his return to Britain. Before he let out for Algiers, he informed fomeof his friends, that the making fuch exciirfions for thefe intercfting purpofes was his principal inducement for accepting the confullhip. How long he continued in Africa, the prcfent writer has not had the opportunity of procuring information ; but having intentions afterwards of viliting Palmyra, he was fliipwrecked on the coaft of Tunis, and plun- dered of every thing by the barbarous inhabitants. The mofl: diftrelhng part of the lofs was probably that of his inflruments, fo nccclfary toa fcientific tra- veller ; and though he afterwards procured fomc of thefe, yet others (particularly a quadrant) could not be recovered. Mr Bruce, however, determining to repair this lofs as foon as polFiblc from France, fo much Jicarer to him than England, was fo fortunate as to be provided with a time-piece and quadrant from that quarter. Upon this occafion Lewis XV. preftntcd him with an iron quadrant of four feet radius, as he had probably reprefented to the academy of fciences his want of fuch an inllrument w'hilll he (liould be in Abyflinia : Mr Bruce brought back with him to Eng- land this cumbrous fellow-traveller, and, having put upon it an infcription to the following purport, is faid to have prefented it to the univerfity of Glafgow : " With this inflrumcnt given by the king of France, Lewis XV. Mr Bruce proceeded to the fources of the Nile, it being carried on foot, upon mens fhoulders, over the mountains of Abyflinia." This information was received from that eminent maker of inllruments Air Nairne. Where and %vhen Mr Bruce received the French inflruments is not known ; but as he was flill bent on viliting Abyflinia, he gave a comniiinon to Mr W. RulTel, F. R. S. for a reflecting tclefcope, made by Bird or Short ; a watch with a hand to point feconds, and the newefl and completeft Englifli aflronomical tables ; all of which were to be fent to Mr Fremaux, and forwarded to him at Alexandria before Auguft. On the 29th of March 1 768, Mr Bruce was at Sidon on the coafl of Syria, and wrote to MrRuflel from thence for the following additional inflruments, viz. a twelve-fecl reflecting telefcope, tobe divided into pie- ces of three feet, and joined with fcrews. This tele- fcope was alfo accompanied by two thermometers and two portable barometers. Mr Bruce moreover infor- ed Mr Ruffel, that he was going into a country (viz.A- byfEnia) from which few travellers had returned ; and wifhed Mr RnfTel, or his philofophical friends, would Abyflinis- lend him their dclidcrata, as he was entirely at their ' >- ' fVrvicc. Mr Bruccaddtd, that if he could not obtain adniiliion into Abyllinia, he ftill would do his bell in the caufe of fcieiice on the eallern coafl of the Red Sea. As Mr Bruce had direftcd the inflruments to be ready for him at Alexandria by the beginning of Au- guft t 768, it is probable that he reached Cairo about that time ; from wlience he proceeded to Abyllinia, by way of Jedda, Mazava, and Arquico. It is fuppoltd that Mr Bruce did not continue long at Jedda, as he is faid to have explored the coafl on the eaft fide as low as Mocha, during which drawings were taken of many curious filh in the Red Sea. Tvlr Bruce mufl alfo have entered Abyllinia, either at the latter end of 1768, or the very beginning of 1769, as he made an obfcrvation in that part of Africa on the 15th of January of that year. In this perilous enterprife he was accompanied by a Greek fervaut (named Micharl), and an Italian paint- er, who probably allifled in the numerous articles which might deferve reprefentation, and wlio died of a Hux before MrBruce's return to Cairo in 1 773. Mr Bruce mull at times alfo have been airided by many others, as his inflruments, apparatus for drawings, and other neccn'arics, t>om their weight and bulk could not be ealily tranfported from place toplnce, and perhaps re- quired bealls of burden. To thefe likew ife nuill be added feveralmedicines which enabled him topcrform cures on the inhabitants, and probably occalioned the good reception he afterwards met with. Such otlier particulars as happened to Mr Bruce, duringhislong refulcncc in this unfrequented country, nuill be left to his own fuperior narrative ; and it fliall fuflice, therefore, only to ftate, that he made a large number of obfcr\ations to lix the (Ituatiuns of places, out of which 31 have been examined and computed by the aflronomer royal. The firfl of thefe obferva- tioiis was madeon the loth of January 1769, and the lafl on the 5th of OiSlober i772i from 30 to 38 de- grees of eafl longiiude from Greenwich, and from 12 to 28 degrees of north latitude. It need fcarcely be faid tlicrefore, that thefe obfervations, which include fo large an extent of almofl unknown country, mufl prove a moll valuable addition to geography ; and the more fo, becaufe the Portugucfe, who firft vifited A- byfhnia, give neither longitude nor latitude of any place in that empire ; and Poncet only two latitudes, viz. thofe of Stnnar and Giefum. As Mr Bruce made the lafl of his obfervations on the 5th of October 1772, it is probable that he might then be on his return to Cairo, through Nubia and Upper Egypt, where he arrived on the 15th of Janu- ary 1773, after an abfence of more than four years ; bringing back with him his Greek fervant, named Michael. Mr Bruce continued at Cairo four months, diiring which time he had daily intercourfe with Mr Antes ; the fubflance of a letter from whom will contain the principal confutation of Baron Tott, and others, who have been incredulous with regard to Mr Bruce's ex- pelled narrative. Mr Antes was born of German parents, who were poireffed of lands in the back fettlcmcnts of Pcnufylva- uia; A B Y [ Abyninia. nia ; and having fhowcd tai Jy abiliiies as a mcclianic, ■ y, removed to Europe, where he dillinguilhed himlelf in the art of watch-making, which he learned w ithoiit ap- prenticclhip. Being a membcrtf the church known by the mmcot U/iitas t'ratru/ii, and commonly called Mo- ravian, he wiflicd to be employed in their millions, and more efpecially that of the fame perfualion elbiblilhed at Cairo, who always have defircd to procure oppor- tunities of inflriicling the Abyllu'ians. Mr Bruce had left Cairo tificen months before Mr Antes came there ; and the intcrcourfe, therefore, be- tw-eeii them firll took place on Mr Brucc's return in 1773. Having given this account of Mr Bruce and Mr Antcs's being Hrrt known to each other, wc Ihall llatc the fubflance of fome information received from the latter, who is now ellabliHied at Kulncck near Leeds, after having rcfiJed eleven years at Cairo. " That Mr Bruce left Cairo in i 768, and proceeded thence by way of Jcdda, M.zkva, and Arcjuico, into Abyllinia. " That in 1771, a Greek came from Gondar (the capital) in Abylfiuii, who had a draught from Mr Bruce on a French Merchant at Cairo (named Kofe) foi- fome hundred: of German crowns, which were paid immediately. This draught was accompanied by a let- ter from Mr Bruce, and was the tiril time that he had been heard of at Cairo fince his departure in 1768. " That after Mr Brucc's return to Cairo in 1775, Mr Antes faw a young Armenian and his father (who came likewife from Gondar) at Mr Pint's, an Italian merchant of Cairo, where they and Mr Bruce con- verfed in the Abyflinian language, and fectned glad to meet him again. " That Mr Bruce returned to Cairo from Abyflinia by way of Nubia and Upper Egypt ; which can be fully attcllcd by the Krancifcan friars who are eftab- liflicd at Ifne near Afyuwan, which latter is the high- eft town of Upper Egypt. " That during Mr Bruce's ftay at Cairo, which was not lefs than four months, no day palfed without their feeing each other ; which gave Mr Antes frequent op- portunities of inquiring with regard to Abyflinia, con- cerning which he was particularly intercfled from a reafon before ftated. " Than Mr Antes likewife frequently converfed with Michael, Mr Bruce'sGreek fervant ; who is ftated to have by no means had a lively imagination, and who 35 ] A B Y always agreed with the circumftances ir.entioned by Ab.ripii. his niaftcr, and more particularly in relation to their • ' having viiittd the fourccs of the Nile ; which the Ba- ron 'i. ott doubts of, fruiu having had a converfatioa with this fame Greek fervant. Mr Antes adds, " That Baron Tott ftaid but a few days at Cairo; and, from his fliort relidencc in that country, hath givenfcvcral erroneousaccounts relative to Egypt. Mr Antes, on the other hand, had almoft daily convcrfations w ith Michael for feveral years, and often in relation to tlie fourcesof the Nile." Lallly, " That after Mr Bruce left Cairo, Mr An- tes had converfed with others who had known Mr Bruce in Abylhnia, and that he was there called Maa- lim Jakiib;, or Mr James. Alter this ftaie oi facts, it is conceived that no one can entertain a reafonable doubt with regard to Mr Bruce's not only having vidtcd, but relided long- in Abyllinia ; though it is remarkable that the Jcfuits ex- prelii/d the fame doubts in relation to Ponccf, \\ ho had continued there nearly as long as Mr Bruce. Poncct happened to be a layman ; and the Jcfuits, perhaps, would not approve of any narrative that did not come from father Benevent, who accompanied Poncct to Abylfinia, but unfortunately died there (a). Driven, however, ("rom this hold, the objectors will poliibly retain their incredulity as to many particulars to be related. The firft of thcfc is, the having vifited the fources of the Nile ; "which, from claflical education, we can- not ealily believe, as they were unknown to the an- cients, though they had fo great curiolity with regard to this difcovery." Many things, however, have been accompliilicd by travellers in modern times, which the ancients ne- ver could atchieve, and which may be attributed to their want of cnterprife (as travellers at leaft), of lan- guages, and laftly the not being able to procure cre- dit when in a diftant country. Mr Bruce could not have continued fo long as he did in Abyflinia, unlefs he had drawn from Gondar upon a merchant eftablifli- ed at Cairo. The dilficulty, however, with regard to reaching the fourcesof the Nile, arifcs principally from the un- civilized ftate of Abyllinia, unlefs the traveller hath a proper introdnclion [h). When once this is procured, all difliculties fecm to ceafe, as we find by Lobo's (f) account of this fame difcovery, and likewife by Pon- E 2 cet's (a) It muft be admitted, however, that wc owe to the zeal of tlie Jefuits the bcft accounts we have both of China and Paraguay. Few laymen have been actuated fo ftrongly for the promotion of geography and fcicnce as Mr Bruce; and we muft therefore (upon the order of the Jcfuits being abolilhed) look up chiefly to the mif- lionaries from the church of the Umtas Fratrum, who, though ililiering fo totally in other rcfpecis, fecm to have an equal ardour with the Jefuits for inftrucling the inhabitantsof countries unfrequented by Europeans. Such milfions are already eftabliihed in W eft Greenland, the coaft of Labrador, N. Lat. 56. the back fettlemcnt? of Carolina and Penfylvania, in India. Bengal, and the Nicobar illands. Thole eftabliihed on the coaft of La- brador fend over yearly mcieoroh.gical journals, which arc communicated to the Royal Society. As for the difpute between Poncec and MailUt the French tonful at Cairo, See Mod. Univ. Hift. vol. ^. {b) The profeflini!; the kno\\ ledge of medicine was Ponect's introduction, and fccms to have been that of Mr Bruce. Even in our own civilized country, how arc quacks and momitebanks reforted to ? And what an imprelfion muft Mr Bruce, with his magniiiccnt and fcientilic apparatus, have made uj'on the i.ihabitant* ot fuch a country as Abyllinia ! (c) In father Telles's c nipilation. Sec alfo LudolfF.who defcribes the fources from Grcgory,who was a native of Abyllinia. Father Pacz was the lirft who vifited them, A. D. 1622. His account of this is faid to be in the archives A 13 Y [ 36 ] A 13 Y A'i}i3n":a. cei's narrative, whu wHsjircvciucd by illntfsfrom vi- ' iiiing tlic very I'liut, but htith given an ample relation from an Abyflinian wlio had olten been there. Pon- eet, moreover, had obtained leave from the emperor to make this journey, which he llates as not being a dillaut one, and that the emperor hath a palace near the very fourccs. If it be doubted whether Mr Bruce hath vilitcd e- very fourcc of the Nile, it may be anfwercd, that per- haps no Ingliflimm hath taken this trouble with rc- •i;ard to the fourccs of the Thames, which, like inofb other great rivers, is probably derived from many fprings and rills in different dire(5lions. The other objection which we have often heard, is, " That Mr Bruce hath mentioned in eonverfation, that the Abylliiiians cut a llicc from the living ox, eActming it one of their grcatcll delicacies." This fort of dainty, indeed, is not fo conlidcrcd in other parts of the globe ; but every nation alniort hath its peculiarities in the choice of their food. Do not we cat raw oyllcrs within a fccoud of their being fepa- rated from the ihell ? And do not we roaft both them andlobllers whiUl alive ; thebarbarity of which prac- tice feems to equal that of the Abyllinians r Do not cooks Ikin eels whilft alive ? And do not epicures crimp lilh for the gratificativm of their appetites. That the Abyllinians eat beef in a raw ftatc, is a- greed both by Loboand Poncet ; and the former fays, re^-kiiig from the beafl. Mr Antes, moreover, was told by a Francifcan monk, who went with the cara- van from Abyllinia to Cairo ((/), that he was witnefs of an ox being killed, and immediately devoured by the band of travellers. One reafon, perhaps, for this ufagc may be, the great heat of the climate, which will not permit meat to bekcpt afullicient time !o make it tender (as with us) : and it is generally allowed, that u fowl, drelfed immediately after it is killed, is in better order for eat- ing than if it is kept four and twenty hours. Is it therefore extraordinary, that an Abyffinian epicure may really Hnd (or perhaps fancy) that apiece cut from the bcall whilrt alive, may be more tender, or have a better relilh, than if it is prcvioully killed by the butcher ? To this maybe added, that according to the information which has been received on this head, Mr Brucc's account of this pradice is much mifrepre- fentcd by the objeftors, who ftippofe that the ox lives a conliderablc time after thcfe pieces are cut from it. When thefc dainty bits, however, have been fentio the great man's table (and which arc probably taken from the flefliy parts), the beall foon afterwards expires, when the firfb artery is cut, in providing dices for the numerous attendants. Upon the whole, the not giving credit to a traveller, bccaufe he mentions an ufage which is very different from ours (and is undoubtedly very barbarous), feems rather to argue ignorance than acutcnefs. This brings to recollection the incredulity which was (hown to another diftinguiflicd travel ler,Dr Shaw J Ahyflinia, who hiving mentioned, in an Oxford common room, Abvirmisii. that foine of the Algcrines were fond of lion's flcfli, ne- ' " ' vcr could obtain any credit afterwards from his bro- ther-fcllowsof the fame college, though many of them were learned men. It is well known, however, tho' Dr Shaw llates this fame circuniftancc in the publica- tion of his travels, that he is ciicj with the grcatell approbation in almoft every part of Kuropc. Sir William Temple fonrcwhere mentions, that a Dutch governor of Batavia, who lived much with one of the mofl confiderable inhabitants of Java, could never ob- tain any credit from him after having mentioned, that in Holland water became a folid body. The traveller who tirll faw a llying filh probably told every one of this extraordinary circumftance as foon as he fet his foot on ihore, and was jirobably diferedittd with re- gard to tlie other particulars of his voyage. The natural caiifc and progrefs of the incredulity which a traveller generally experiences, feems to be the following : When he returns from a diftant and little frequented country, every one is impatient to hear his narrative ; from which, of courfc, he felcds the more llriking parts, and particularly the ufuges which ditfer moll from our own. Some of the audience, dilbelieving what tlic traveller hath mentioned, put quelUons to him which fliow their dillrufl. The traveller by this treatmentbecomes irritated, andanfwers fome of them peevilhly,othersironically, of which the interrogators afterwards take advantage to his prejudice. Nothing is more irritating to an ingenuous perfon than to find his alfertions are dilbelieved. This is commonly ex- perienced in the crofs examinations of almoft every witnefs. To the diftrclfes of the traveller on his re- turn, we may add, the being often tcafed by \ery ig- norant queflions. ABYSSINIAN, in ecclefiaftical hiftory; is ufcd as the name of a feft, or liercfy, in the Chriftian church, eftablillicd in the empire of Abyffinia. The Abyllinians aie a branch of the Copis or Jacobites ; with whom they agree in admitting but one nature in Jefus Chrill, and rejedling the council of Chalcedon : whence they arc alfo called Kutychians, and ftand oppofed to the Melchitcs. They are only diftin- guiflicd from the Copts, and other (eels of T.icobites, by fome peculiar national ufages. — The Abyilinian feft or church is governed by a bilhop or metropolitan ftylcd Abuna, lent them by the Coptic patriarch of Alexandria rclidiiig at Cairo, who is the only perfon that ordains pricfts. The next dignity \i that of Ko- mos, or Hcgumenas, who is a kind of arch-prcft)ytcr. They have canons alfo, and monks: the former of whom marry ; the latter, at their admiflion, vow celi- bacy, but with a refcrvation : thefe, it is faid, make a promife aloud, before their fuperior, to keep chaftity ; but add, in a low voice, asymt keep it. The emperor has a kind of fuprcmacy in ecclefiaftical matters. He alone archives of the college de propaganda fide at Rome. It is believed that there are many other curious particu- lars for the illuftration of geography to be found in the fame depofitory. Dr Sfliaw mentions, moreover, fome papers of Lippi (who accompanied the French cmbalfy into Abyllinia, A. D. 1704)7 which are to be found in the botanical library at Oxford. ((/) This points out another clTanncl by which a traveller of entcrprifc may vifit Abyffinia.

Under the emperor Sultan Seghed all was andone again; the Rom ill] milTionaries fettled there had their churches taken from tliem, and their new converts banilhed or put to death.

On the other Land, they celebrate the epiphany with peculiar fefli- vity, in memory of Chrifl's baptifn: ; when they plunge and fport in ponds and rivers ; which has occafioned fome to affirm that they were baptized anew every year. Among the faints-days is one coiifecraied to Pi- late and his wife ; by reafon Pilate walhed his hands before he pronounced fentence on Chrift, and his wife defired him to have nothing to do with the blood of that juft perfon. They have four lents: the great one comraeiices ten days earlier than ours, and isobfcrvcd with much fcverity,many abflaining therein even from fifh, becaufe St Paul fays there is one kind of fie(hof men, and another of filhes. They allow of divorce, which is eafily granted among them, and by the civil judge ; nor do their civil laws prohibit polygamy it- felf.

The {lowers of a fpecics of the acacia are ufcd by the Chincfe in making that yellow, which wc fee bears walhing in their lilks and ftufFs, and appears with fo much elegance in ilieir painting on paper. The method is this : They gather the flowers before they are fully open ; thcfe they put into a clean earthen veiltl over a gentle heat, and ilir them continually about, as they do the tea-leaves, till they become dryifh and of a yellow co- lour ; then to half a pound of the tlowcrs they add three fpoonfuls of fair water, and after that a little more, till there is jull enough to hold the flowers in- corporated together : they boil this forfonie time, and the juice of the dowers mixing with the water, it be- comes thick and yellow ; they then take it from the fire, and flrain it through a piece of coarfc lilk. To the liquor they add half an ounce of common alum, and an ounce of calcined oyrter-lhells reduced to a fine powder. All is then well mixed together ; and this is the fine lafling yellow they have fo long ul'cd. The dyers of large pieces ufe the flowers and feeds of the acacia for dying three different forts of yellow. They roait the flowers, as before obfcrvcd ; and then mix the feeds with them, which muft be gathered for this purpofe when full ripe : by different admixture of thefe, they give the different Ihades of colour, on- ly for tlic deepeit of all they give a fmall mixture of Brazil wood. Mr Geoffroy attributes the origin of bezoar to the feeds of this plant; which being broufcd by certain animals, and vcUicaiing the flomach by their great fournefs and aflringcncy, caufe a condenfation of the juices, till at length they become coated over with a ilony matter, which we call bezoar.

This juice is brought from Egypt, in roundiih malhcs, wrapt up in thin bladders.

It foon foftens in the juouth, and dif- covcrs a rougii, not difagrecable talle, which is fol- lowed by a fweetilh rclilh.

ACADEMICI.AN, or Academist, a member of an academy. Sec Academy in a modern fenfc. ACADEMICS, or Academists, a denomination given to the cultivators of a fpecies of philofophy ori- ginally derived from Socrates, and afterwards illu- flraied and enforced by Plato, who taught in a grove near Athens,eonfccraied to the memory of Academus, an Athenian hero ; from which circumftance this phi- lofophy received the name o( acndoiucjl. Before the days of Plato, philofophy had in a great meafure fallen into contempt. Tlte coniradidlory fyftems and hypoihcfcs which had fucceffively been urged upon the world were become fo numerous, that, from .1 view Aca.1fniic« ofthisiiiconllancyand uncertainty of human opinions, ( many were led to conclude, that truth lay beyond the Acail einy.^ reach of our comprehenfion. Abfolute and univcrfil ' " ' fcepticitm was the natural confequencc of this conclu- iion. In order to remedy this abufc of philofophy and of the human faculties, Plato laid hold of the principles of the academical philofophy ; and, in his Phaedo, reafons in the following manner. " If we arc " unable to difcover truth, (fays he), it mull be owing '< to two circumflances : cither there is no truth in <' ihe nature of things j or the mind, from a defect "in its powers, is not able to apprehend it. Upon " the latter fuppolition, all the uncertainty and tiuc- " tuation in the opinions and judgments of mankind " admit of an eafy folution: Let us therefore be mo- " dell, and afcribc our errors to the real weaknefs "of our own minds, and not to the nature of things " themfelves. Truth is often difficult of accefs; in " order to come at it, vre mull proceed with caution " and diffidence, carefully examining every ftep j and "after all our labour,we will frequently find our grcat- " ell efforts difappointcd, and be obliged to confefs our " ignorance and weaknefs." Labour and caution in their refearchcs, in oppofi- lion to rafn and hally decifions, were the dillinguilhing charaCleriflics of the difciples of the ancient academy. A philofophcr, polieiled of thefe principles, will be How in his progrcfs ; but will feldom fall into errors, or have occafion to alter his opinion after it is once formed. Vanity and precipitance arc the great fources of fcepticifm. Hurricdon by thcfeindcad of attending to the cool and deliberate principles recommended by the academy, fcveral m.odern philofophers have plunged themfelves into an abfurd and ridiculous kind of fcepticifm. They pretend to defcredit fubjeifls that are plain, (imple, and eafily comprehended ; but give peremptory and decifive judgments upon things that evidently exceed the limits of our capacity. Of thefe, Berkley and Hume are the mod confidcrable. Berkley denied rhe exiflence of every thing, excepting his own ideas. Mr Hume has gone a Hep further, and qucftioncd even the exiflence of ideas ; but at the fame time has not helitatcdto give determined opinions w'ith regard to eternity, providence, and a future ftate, miraculous intcrpolitions of the Deity, &c. fubjeds far above the . reach of our faculties. In his eflay on the academical or fceptical philofophy he has confounded two very oppofite fpecies of philofophy. After the days of Plato, indeed, the principles of thetirfl academy were grofsly corrupted by Arcefilaus, Carneadcs, &c. This might lead Mr Hume into the notion that the academica/and faptkal philofophy were fynonymous terms. But no principles can be of a more oppofite nature than thofe which were inculcated by the old academy of Socrates and Plato, and the fceptical notions which were pro- pagated by Arcelilaus, Carneades, and the other difci- ples of the ficcceding academics. ACADEMY, in antiquity, agardcn, villa, or grove, fituated within a mile of Athens, where Plato and his followers held their philofophial conferences. It took its name from one Academus, or Ecademus, who was the originalowncrof it, and made it a kiadof gymna- fium : he lived in the time of Thcfeus ; and, after his death, it retained his name, and was coufecrated to his A C A [ 39 ] A C A his memory. Cimon cmbcllilhcd it with fountains, trees, and walks ; but Sylk, during thclicgc of Athens, employed thclc very trees in makinji; battering engines again!! the city. Cicero too had his villa, or place of retirement, near Puziuoli, which he alio named an acadimy, where he compofcd his Ai-iidimkaiqueflhns, and his book Di uMitradibnim. Academy, among the moderns, is mod commonly ufcd to fignify a society of learned men eftablilhcd for the iinprovcment of any art or fcieuce, and gene- rally uhdtr the protcdlion of a prince. The tirft; Academy wc read of, was eftablilhed by Charlemagne, at the infligation of Alcuin. It was compol'ed of the chief wits of the court, the emperor himfclf being a member. In their academical con- ferences, every perfon was to give an account of what ancient authors he had read ; and each even alTumed the name of fomc ancient author who plcafed him molt, or fome celebrated perfon of antiquity. Alcuin, from whofc letters we learn thefe particulars, took that of Flaccus, the fitnamc of Horace ; a young lord, named Augilbert, took that of Homer : Adelard, bifliop of Corbie, was called Augullin : Riculfc, bilhop of Mentz, was Dametas ; and the king himfclf, David. This ihows the miftake of fome modern writers, who re- late, that it was in conformity with the genius of the learned men of thofe times, who were great admirers of Roman names, that Alcuin took the name of Flac- cus Albinus. Mofl nations have now their academies ; but Italy has the greatell number The French have many flourilhing academies, mofl of which were cftabliflicd by Lewis XIV There are but few in Britain ; and ihofc of chiefell note go by a different name. See tiic article Socie r v. In giving an account of the principal Academies, it feems mofl proper to arrange them according to their fubjecls. I. Medical Aeadsmies, as that of the Naturae Cu- rioli in Germany ; that founded at Palermo in 164J : another at Venice in i 701, which meets weekly in a hall near the grand hofpital ; another at Geneva in 1715, in the houfe of M. Le Clerc. The colleges of phyficiansat London and Edinburgh are alfo, by feme, ranked in the number of Academics. The Academy o( Naturx Curioji, called alfo the Lcopoldine Academy, was founded in i6j2, by Jo. Laur. Baufchius, a phyfician ; who, in imitation of the Englilh, publidied an invitation to all phyficians to communicate their extraordinary cafes ; and, meeting with fucccfs, waseledcd prefident. Their works were at firft publiflied feparately ; butin i67oanew fcheme was laid for publiihing a volume of obfcrvations every year. Tlie firll volume appeared in 1684, under the title of Ephemerides, and the work has been continued with fome interruptions and variations of the title, crc. In 16S7, the emperor Leopold took the fociety under his protection, granting the members feveral privileges, particularly that their prcfidents Ihould be counts pa- latine of the holy Roman empire. This academy has no fixed rcfidence, nor regular afi'emblics ; infteadof thefe, there is a kind of bureau, or ofRce, firfl cftabliQi- cd at Brcllau, and afterwards removed to Nuremberg, where letters, obfervations, b-c. from correfpondents or members arc taken in. The academy confiAs of a 3 prcfiienc, two adjuncts or fecretaries,snd colleagues or Ai-ademie*- members without reftriclion. Thccolleagucs, at their >- admiluon,obligethenifclvcstotv.-othings:lirll,tochoofc fome objcel out of the animal, vegetable, or mineral kingdom, to handle, provided it had not been treated of by any colleague before : the fecond, to apply them- felvestofurnifh materials for theannual Ephemerides. Each member to bear a fymbol of the academy ; ■aiz. a gold ring ; whereon, inllead of a ftonc, is a book open, and, on the face thereof, an eye; on the other fide the motto of the academy, Nunqiiani iiulfus. II. Chirurgical Acidcwks ; as that inftitutcd fome years ago, by public authority, at Paris : the mem- bers of which were not only to publilhtheirown and correfpondents obfervations and improvements ; but to give an account of all that is publiiliedon furgcry,and to compofe a complete hillory of the art, by their extracts from all the authors ancient and modern who have wrote on it. A quellion in furgcry is an- nually propofed by the academy, and a gold medal of 2C0 livres value given to him who furnifhcs the moft fatisfaclory anfwer. Academy of Surgery at Vieniiii, was inftituted fome years ago by the prtfent emperor, under ihcdiredlion of the celebrated Brambilla. In this there were at firfl only two proftifors ; and to their charge the in- llrudion of 130 young men was committed, 30 of wliom had formerly been furgeons in the army. But of late the number both of the teachers and pupils has been confidtrably increafed. Gabrielli has been appointed to teach pathology and praftice; Boecking, anatomy, phyliology, and pliyfics : Streit, medical and pharmaceutical furgery ; Hunczowlky, furgical opera- tions, midwifery, and thcchirurgiaforenfis; and Plenk, chemiftryand botany. To thefe alfo has been added, Bcin*!l, as profedor and extraordinary profcflbr of furgery and anatomy. Befides this, the emperor, with his ufual liberality, has provided a large and fplenJid edifice in Vienna, which affords Iiabitation both for the teachers, the lludents, pregnant women, patients for clinical leftures and fcrvants. He has alfo purchafed for the ufe of this academy a medical library, which isopeneveryday : a complete fetof chirurgical inftru- mcnts; an apparatus for experiments in natural philo- fophy ; a coilcdion of natural hiftory ; a number 01 anatomical and pathological preparations ; a colleflion of preparations in wax brought from Florence; and a variety of other ufeful articles. Adjoining to the building alfo there is a good botanical garden. Among other parts of this inftitution, three prizc- mcdals, each of the v.-iluc of 40 liorins, are to be an- nually bellowed on thofe lludents who return the bell anfwer toqucllions propofed the year before. Thefe prizes are not entirely founded by the emperor, but arc in part owing to the liberality ot Brcndellius the protochirurgus at Vienna. III. KccLtsiA'^TiCAL Acadniiits ; as that of Bologna in Italy inftituted in ib'^T, troplnycd in the examina- tion of the doctrine, difcipline, and hillory, of each age of the church. IV. Co^yocRAfHicAL Acad;n/ionarj-,aJfoc/al(j, and I'/t-cc-/. Thtfe laft were a kind ot pupils, or fcholars, each of whom was at- tached to one of the pcufionaries. The firft clafs to contain ten perfons,and each of the reil twenty. The honorary academilts to be all inhabitants of France ; the pcnlionaries all to refide at Paris ; eight »f the af- fociates allowed to be foreigners ; and the eleves all to live at Paris. The oificcrs to be, a prelidcnt named by the king, out of the clafs of honorary academics ; and a fccrctary and trcafurcr to be perpetual. Of the penfionarics, three to be geometricians, three aftrono- lacrs, three mechanics, three anatomiils, three che- iiiifts, three botanifls, and the remaining two to befe- cretary and treafurer. Of the twelve allbciatcs, two to apply thcmfcives to geometry, two to botany, and two to chcmiftry. The eleves to apply themfelvcs to the fame kind of fcience with the pcnlionaries tlicy were attached to ; and not to fpeak except when call- ed by the prelidcnt. No regular or religious to be ad- mitted, except into the clafs of honorary acadeinirts ; nor any perfon to be admitted either for allbciate or penlionary, unlefs known by fomc confiderable printed work, fome machine, or other difcovcry. The aflem- blies were held on Wcdnefdays and Saturdays, unlefs cither of them happened to be a holiday, and then the alfembly was held on the preceding day — To encou- rage the members to purfue their labours, the king engaged not only to pay the ordinary penfions, but e- ven to give extraordinary gratifications, according to the merit of their refpcc^ivc performances ; furnilhing withal the expence of the experiments and other in- quiries necelfary to be made. If any member gave in a bill of charges of experiments he had made, or dcfir- ing the printing of any book, and brought in the char- ges of graving, the money was immediately paid by tlie king, upon the prefident's allowing and fignJng the bill. So, if an anatomift required live tortoifcs, for inllancc, for making experiments about the heart, &c. as many as he plcaicd were brought him at t lie king's charge. Their motto was, hwcnil ct psrj^-cit. In the year i 716, the duke of Orleans, then regent, made an alteration in their conftitution ; augmenting the number of honorarics, and of aiR>ciates capableof being foreigners, to 12; admitting regulars among filch allbciatcs ; and fupprefling the clafs of clcvcs, as it appeared to be attended with fomc inconveniences, particularly that of making too great an inequality a- mong the chcmills, and being prodnclive of fome inif- ii>ideril,indings and aniinofitits among the members. At the fame time he created other two claifes ; one con- fiding of 12 adjuncts, who, as well as the aifctiates. Were allowed a deliberative voice in matters relative to fcience ; and the other lix free aifociatcs, who were not attached to any particular fcience, nor obli- ged to purfue any particular work. Since its rc-ellablirtvnient in 1696, this academy has Vo:.. I. been very exact in publilliing, every year, a volume AcmJemiet containing cither the works of its own members, or " fuch memoirs as have been compofed and read to the academy during the courfe of that year. To each vo- lume is prefixed the hilloryof the academy, or an ex- tract of the memoirs, and, in general, of whatever has been read or faid in the academy ; at the end of the hiflory, are the eulogiums on fuch icadeinills as have died that year. — M. Kojille de Meflay, counfcUor to the parliament of Paris, founded two prizes, one of 2JC0, and the other of 2CX3o livres, which are alter- nately dillribiited by the parliament every year ; the fubjed for the firft mull relate to phy ileal ailronomy, and thofc for the latter to navigation and commerce. Notwithrtanding the advantages which the members of this academy enjoy over others, in having theirex- pences defrayed, and even being paid for their time and attendance, they have fallen under fome imputa- tions, particularly that of plagiarifin, or borrowing their neighbour's inventions ; but with what jufticc we do not fay. The French have alfo confiderable academiesinmofl of their great cities : as, at Montpelicr, a royal aca- demy of fcienccs on the like footing as that at Paris, being as it were a counterpart thereof; aiThouloufc, an academy under the denomination of Lanternifls ; others at Nifmes, Aries, Lyons, Dijon, Bourdcaux, &c. The Royal Academy of Sciences at Berlin was founded in 1700, by Frederic 11. kingofPruflla, on the model of that of England ; excepting that, befides natural know- ledge, it likewife comprehends the Belles Lettres. In 1710, it was ordained that the prclident iTiall be one of the counfellors of llate, and nominated by the king. The members were divided into four clalies ; thefirll for profecuting phylics, medicine, and cheraiflry; the fecond for mathematics, aftronomy, and mechanics ; the third for the German language and the hiftory of the country ; the fourth for oriental learning, parti- cularly as it may concern the propagation of the gof- pel among infidels. Each clafs to eled a diredor for thcmfcives, who (liall hold his poll for life. The mem- bers of any of the claifes have free admillloaintu the alfemblies of any of the reft. The great promoterof this inftitution was the cele- brated Mr Leibnitz, who accordingly was made the firft diredor. The firft volume of their tranfadions was publiflied in 1710, under the title oi MifcdUmea Deroiineiijia ; and though they received but few marks of the royal favo;ir for fome time, they continued to publilh new vohiincs in 172;, I72j, 17^4, and 1740. At laft, however, Frederic III. the late king of Pruf- fia, gave new vigour to this academy, by inviting to Berlin fuch foreigners as were moft dillingiiilhed for their merit in literature, and encouraged his fubjefts to profecute the lluJy and cultivation of the fcienccs by givingample rewards ; andthinking that iheacade- my, which till that time had had fome minillcr nr opu- lent noblenum fori;s prefident, would find an advan- tage in having a man of letters at its head, he confer- red that honour on M. Maupertuis. At the fame time, he gave a new regulation to the academy, and took upon himltlf the title of its protedor. The academifts hold two publicaii'emblies annually ; one in January, on the hte king's birth-day ; and the F other A C A I 42 ] A C A Acadcn'.iei. other in >'ay, on thed.iy ol'liisacccflion to the throne. ■■~~^' — At the latter ot thdc is j^ivcn, as a I'rizc, a gold nic- lial of JO diicais value : the fiibjeiit for tliis prize is fuccellively, natural philolbpliy, niaihcuiaiiti, meta- phylics, and erudition. The Ivipinal Aiadiviy of Sciences at Fctcr/hiirgh was projected by Czar I'ttcr the Great. That great monarch having, during his travels, obfcrved the ad- vantage of public focitlies for the encouragement and prouii'iion ot litrrature, fornicu the deiign of founding an academy of fcienccs at btPcterlLurgh. l>y the ad- vice of Wolf andLcibnifz, whom he confulted on this occalicn, the fociety was regulated, and fcvcral learn- ed foreigners were invited to become members. Peter himfclf drew the plan, and llgned it on the loth of l''eb. 1724 ; but was prevented, by the fuddennefs of his death, from carrying it into execution. His dc- ccafe,huvvcver, did not prevent its completion : for on the 2 1 it of December 1725, Catharine I. eliablilhed it according to Peter's plan ; and on the 27th of the fame month the fociety was firfl alleuibled. On the iftof Auguft 1726, Catharine honoured the meeting with her prefencc, when profellbr Bultinger, a German natiiralill of great eminerce pronounced an oration upon the advances made by the loadllone and needle lor the difcovcry of the longitude. The emprefs fettled a fund of 4982I. per annum for the fupport of the academy ; and fifteen menibtrs, all eminent for their learningand talents, were admitted . and pcnlioned, under the title of Profellors, in the va- rious branches of literature and fcience. Tlie mofl dillinguiflied of thcfc protellbrs were Nicholas and Da- niel Bernouilli, the two De Lilies, Bullingcr, and Wolf. During the fliort reign of Peter II. the falaries of the members were difcontinued, and the academy was utterly neglcttcd by the court ; but it was again pa- tronized by the enipreis Anne, who even added a fc- minary for the education of youth, under the fuperin- tendunce of the profellors. Both inllitutions tlourilhed for fomelimc under the direction of Baron Korf ; but upon his death, towards the latter end of Anne's reign, an ignorant perfon being appointed prefident, many of the molt able numbers quitted Ruflia. At the accef- fion of Elizabeth, new life and vigour were again rc- ftored to the academy : the original plan was enlarged and improved ; fome of the moll learned foreigners were again drawn to Pctcrlburgh ; and, what was con- fiJcred asagood omen for the li;erature ofRulfia, two natives, Lomoaofof and Rumovfky, men of gciiiusand abilities, who had profecuted tJicir fludies in foreign univerfitics, were enrolled among its members. The annual income was incrcafed to 10,659!. and foon af- terwards the new inflitution took place. The prefcnt emprefs Catharine III. with her ufual zeal for promoting the diffulion of knowledge, has ta- ken this ufeful fociety under her more immediate pro- tection. She has altered the court of dirertors greatly to the advantage of the whole body ; (lie has corrected many abufes, and has infuftd a new fpirit into their rcfearehes. By her majefly's particular recommenda- tion, the moll ingenious profellors have vilited the va- rious provinces of her vafl dominions ; and as the fund of the academy was not fufiicient to fupply the whole expence of thcfe fevcral expeditions, the emprefs be- ilowed a largefs of 20&cl. vviiich Ilic has renewed as Acadetiiiei. occaliou has required. ' •^ ' 'l"hc piirpofe and intent of thefe travels will appear from the iiillructions given by the academy to the fe- vcral perfons who were engaged in them. They were ordered to purfue their inquiries upon the different forts of earths and waurs ; upon the bell methods of cultivating the barren and delart fpots ; upon tlie local diforders incident to men and animals, and the moll cflicacious means of relieving them; upon the breeding of cattle, and particularly of Ihcep ; on the rearing of bees and filk-worms ; on the dilierent places and ob- jects for tilhing and hunting ; on minerals ; on the arts and trades ; and on forming a Klora Rulfica, or eoUcc- tionof indigenous plants: they were particularly in- ilruiled to rectify the longitude and latitude of the principal towns ; to make allronomical, geographical, and meteorological obfervations ; to trace the courfc of the rivers ; to take the molt exav.^t charts ; and to be very dillinet and accurate in remarking and defcribing the manners and cnltoms of the different people, their drelfes, languages, antiquities, traditions, hiltory, re- ligion ; and, in a word, to gain every information which might tend to illullralc the real Hale of the whole Ruliian empire. In confequence of thefe expeditions, perhaps no country can boall, within the fpace of lb few years, fuch a number of excellent publications on its internal • Hate, on its nalsral produ(!:tions, on its topography, geography, and hiltory ; on the manners, cuftoms, and languages of the ditterent people, as have illucd from the prefs of this academy. The iirft tranfaftions of this fociety were publiflied in 1 728, and intitled Commentarii Acader/iia Scienti- arutn Imperialii Pftropclitanit ad an. 1726, with a dedication to Peter II. The publication was conti- nued under this form until the year 1747, when its tranfactions were called Novi Cfiiiiineiitarii Acadetnia, &c. In I 777 the academy again changed the title in- to ACla Acadetnia Scientiariifn Ir/iperial'ts Petropoli' tarne, and likewife made fome alteration in the ar- rangement and plan of the work. The papers, which had been hitherto publiflied in the Latin tongue, arc now written either in that language or French; and a preface is added, ftyled Partic Hijiorique, which con- tains an account of its proceedings, meetings, admil- fion of new members, and other remarkable occur- rences. Of the Commentaries, 14 volumes were pub- liflied : the firfl of the New Commentaries made its appearance in 1750, and the twentieth in 1776. Un- der the new title oi Aiia Academic, fevcral volumes have been given to the public, and two arc printed every year. Thefe tranfaiitionsabound with ingenious and elaborate difquilitions upon various parts of fcience and natural hillory, and which rctlccT; the greatell ho- nour upon their authors; and it may not be an exag- geration toalTert, that no fociety in Europe has more diftinguiflied itfelf for the excellence of its publications, and particularly in ihe more abflrufe parts of the pure and mixed mathemaiics. The academy is flill compofed, as at firft, of fifteen profeflbrs, befide the prelldent and direc'or. Each of thcfe profelforshas a houfe and an annual Itipcnd from 2Col. to 600I. Belide the profeflbrs, there are four adjuncts, who are peuUoued, and who are prcfent at the A C A [ 43 ] A C A Academies, the fittings of the focicty, and fuccecd to the firfl va- »— V— — ' cancies. — The dircftioii of the academy is at prcfent configned to the Princefs DaQiliof. The building and apparatus of this academy are ex- traordinary. There is a fine library, confiding of 36000 curious books and manufcripts Tiicre isan extenii vc niufcum, in which the various branches of natural hi- Aory, &c. arc dirtributed in different apartments : it is extremely rich in native productions, having been con- fiderably augmented with a variety of fpccimens col- lected by Pallas, Gniclin, Guldenftaedt, and other learned profellbrs, during their late expeditions thro' the Ruifian empire. The fluffed animals and birds occupy one apartment. The chamber of rarities, the cabinet of coins, &c. contain innumerable articles of the highell curiofityand value. The fociety has this motto, Paulatim. The Academy of Sciir.ca at Bologna, called the Injil- tute of Bologna, wzi founded by count Marfigli in 171 2, for the cultivating of phyfics, mathematics, medicine, chemiflry,and natural hiflory. Its hilloryis written by M. de Limiers, from memoirs furnilhed by the founder himfclf. The Academy of Sciences at Stockhohn, or Royal Swedip? Academy, owes its inflitution to fix perfons of diftinguifhed learning, amongfl whom was the celebra- ted Linnaeus: they originally met on the jj of June 1 739, formed a private fociety, in which fomc diiFer- tations were read ; and in the latter end of the fame year their firfl publication made its appearance. As the meeting continued and the members increafed, the fociety attracted the notice of the king, and was, on the 31ft of March 1741, incorporated under the •name of the Royal Swedilh Academy. Not receiving any penlion from the crown, it is only under the pro- tedion of the king, being dircded, like the Royal Society, by its own members. It has now a large fund, which has chiefly arifeu from legacies and other donations ; but a profcffor of experimental philofophy, and two fecretaries, are flill the only perfons who re- ceive any falaries. Each of the members rchdent at Stockholm becomes prefident by rotation, and conti- nues in office during three months. There arc two fpeciesof members, native and foreign : the cledionof the former is held in .'\pril, and of the l.uter in July : no money is paid at the time of admiilion. The dif- fcrtations read at each meeting are collected and pub- liflied four times in the year; they are written in the Swedilh language, and printed in oJlavo, and the an- nual publications make a volume. Tiie lirft 40 vo- lumes, which were finillied in 1779, arc called the Old Tranfaclions ; for in the following year the title was changed into thit of New Tranfaclions. The king is fometimes prefentat the ordinary meetings, and par- ticularly at the annual affembly in April lor the elec- tion of members. Any pcrfon who fends a treatife which is thought worthy of being printed, receives the tranfadions tor th.tt quarter ^r ife a ■« 0- mm who iUndi lor a model in the public fchool. Every three months, three prizes for delign arcdidri- butcd among the eleoes or dildples ; two others for painting, and two for i"culpture every year.

It confiils of a diredlor, four ccnlors, a fccretary, and 50 members ; to each of '.vhom isalligncd fomepirt of the ccclcfiatli- cal or civil iiiilory of the nation', which he is to treat either in Latin or Portugnefe.

IX. Academies (yf AsTiSi/irlES ; as that at Corto. na in Italy, and at Upfal in Sweden. The firft is defigncd for the ftudy of Hctrurian antiquities ; the other for illuflrating the northern languages, and the antiquities of Sweden, in which notable difcovcrics have been made by it. The head of the Hctrurian academy is called Lucomon, by which the ancients go- vernorsof the country were diftinguilhcd. Oneoftheir laws is to give audience to poets only one day in the year ; another is to fix their feflions, and impofc a tax of a dilfcrtation on each member in his turn. The Academy of Medals and Infcriptions at Paris was fet on foot by M. Colbert, under the patronage of Lewis XIV. iii 1663, for the ftudy and explanation of A C A [ 45 D A C A AcademicB. oF r.ncicnt monunicnts, and perpetuaiiiig great and ■ memorable cvcjits, elpecially tliolc ot the trench mo- narchy, by coins, relievos, infcriptions, &c. The number or members at firlt was confined to four or live, choicn out of tJiofe of the French academy ; who met in the library of Mr Colbert, from whom they received his mijcity's orders. Thcdaysof tli^ir meciings were not dtitrmined ; but generally they met on Wedncl'days, efpecially in the winter fcafon : but, in 1691, the king having given the infpcftion of this academy to M. dc Pontchartrain comptroller ge- neral, &c. he lixcd their meetings on Tuefdays and Saturdays. By a new regulation, dated the 16"' of July i 701, the academy was compofcd of ten t^Onorarji members ; ten ajjocialfj, each of whom had two declarative voices ; ten />cn/ion(iii(j ; and ten elevis, or pupils. They then met every Tucfdayand Wcdncfday,inoneof the halls of the Louvre ; and had two public meetings yearly, one the day alter Martinmas and the other the 16''' after Ealler. The clafs of elevcs Jias been fupprcflcd, and united to the alFociates. The king nominates their prefidcnt and vice-pre(ident yearly ; but their fecrcta- ry and trcafurcr arc perpetual. The rcil are chofcn by the members themfclves, agreeably to the conlli- tutions on that behalf given them. One of thefirfl; undertakings of this academy, was to compofe by means of medals, a conncifted hiftory of the principal events of Lewis XI V's reign : but in this defign they met with great difficulties, and of confe- queiicc it was interrupted for many y;ears ; but at length it was completed down to the advancement of the duke of Anjou to the crown of Spain. In this celebrated work, the cflabliflimeni of the academy itfclf was not forgot. The medal on this fubjcd reprefents Mercury fitting, and writing with an antique ftylus on a table of brals , he leans with his left hand upon an urn full of medals, and at his feet arc fcveral others placed upon a card : the legend, Reruvi gefl drum fides ; and on the exergue, /!:jd:tn:ti reg'u hifcriptionum et Kumifmatiu/i, iiijlitiita M.DC.LXIIL fignifying that the Royal Academy of medals and Jn- fcriptions, founded in 166;, ought to give to future ages a faithful tellimony of all great adlions. Befides this work, wc have fcveral volumes of their memoirs ; and their hillory, wcittcn and continued by their fe- creiaries. X. Acaiimits of B ELLES Lettrf.^ , are thofe where- in eloquence and poeiry are chictly cultivated. Thefe arc very numerous in Italy, a:id not uncommon in France. The Academy cf Umidi at Fhrcncc has contributed greatly to the progrefs of the fcicnces by the excel- lent Italian tranilations given, by fome of its members, of the ancient Greek and Latin hiftorians. Their chief attention is to the Italian poetry, at the fame time that they have applied thcmfclvts to the pulilh- ing of their language, which produced the Academy del la Cri/fca, The Academy of Humorifis, Umori/li, had its origin at Rome from the marriage of Lorenzo Marcini, a Roman gentleman ; at which fcveral ptrfons of rank were gucfts ; and, it being cam:' al time, to give the ladies fomedivcrfion, they took t!:cml'clves to the re- citing of vcrfes, fonuets, fpcechcs, lirAfxr^w/erc, and aficrwards premeditatcly ; which gave them the dcno- Acadcmici- minaiionof ^t/// //««,j,/7. After ionic experience, co- ^ — ' ming more and more into tlic lalle of iheic exeicifes, they rcfolved to form an Academy cf Belles Lcttres ; and changed the title of Belli hnmin for that of Hii- Piorijli : choofing for their device, a cloud, which, after being forn.cd of exhalations from the fait waters of the ocean, returns in a gentle fwcet Ibowcr ; with this motto from Lucretius kedttagmine duU't. In 1690, the Academy c/Arcadiwzs eftablilhed at Rome, for reviving the ftudy of Poetry and of ihc Belles Leilres. Befidcs molt of the politer wits of both fexes in Italy, this academy comprehends many princes, cariiinals, and other ecclcfiaflics ; and, to a- void difputes about pre-eminence, all appeal' malked after the manner of Arcadian Ihcpherds. W ithin ten years from its ^rll eltabliflimcnt, the number of Aca- dei/iijls amounted to (ix hundred. They hold aifcm- blies fevcn times a-ycar in a mead or grove, or in the gardens of fome noblemen of dillinction. Six of thcfc meetings are employed in the recitation of poems and vcrfes of the Arcadi rc;iding at Rome ; who read their own compofitions ; except ladies and cardinals, who are allowed to employ others. The ftvcnth meet- ing is fee apart for the compolitions of foreign or ab- fcnt members. This academy is governed by a Cuflos, who repre- fents th^ whok fociety, and is chofen every four years, with a power of electing 12 others yearly for his af- fiftauce. Under thefe arc two fub-cullodcs, one vicar orpro-cuflos, and four deputies or fuperintendants, an- nually chofen. The laws of the fociety arc immuta- ble, and bear a near rcfcmblance to the ancicjii model. There arc five manners of clefling members. The firfl is by acclamation. This is nfcd when fovcrciui: princes, cardinals, and ambalfadors of kings, defirc to be admitted ; and the votes are then gircn viva voce. The fccond is called an>iumeratio/i. This was intro- duced in favourofladicsandacadcmicalcolonic5,whcrr the votes arc taken privately. The third reprefenta- tion, was eltablilhed in favour of colonies and univcr- fities, where the young gentry arc bred ; who have each a privilege of recommending one or two mem- bers privately to be balloted for. The fourth, farro- giition ; whereby new members arc f.ibllituted in the room of thofe dead or expelled. The lalt, dejiuiatun whereby, when there is no vacancy of members, per- fons of poetical merit have the title of Arcadi con- fcrcd upon them till fuch time as a vacancy (hall hap- pen. All the members of this body, at their admif- lion, alfume new p.-iftoral names, in imitation of the flicphcrds of Arcadi.t. The academy has fcveral co- lonies of A. rcadi in different cities of Italy, who arc all regulated after the fame manner. XI. Academies cf Lascvaghs ; called, by fome, Craintiiaihal Academies : 35. The Ae^de/ny del/a Crnfca at Florence, famous for its vocabulary of the kalian tongue.was formed in i J82, but fcarce heard of before the year 1584, when it be- came noted for a difpurc between Talfo and feveralof its members. Many authors confound this with the Florentine academy.

In 1635, it was erected into an academy, by Cardinal Richlieu, for rcliniiig and afcert.iining the French lan- guage and llile. — 'I he number of its members are li- mited at 40 ; out of whom a director, chancellor, and Iccretary, are to be chofen : the two former hold their port for two months, the latter is perpetual. The mem- bers of this academy enjoy fcveral privileges and im- munities, among which ib that of not being obliged to anfwer before any court but that of the king's houfe- hold. They meet three times a-wcek in the Louvre ; at breaking up, 40 lilver medals arc diftributcd among them, having on one fide the king of France's head, and on the rcverfc, Prtt.cUur dil' Acadtmii, with lau- rel, and this motto, A /' Itnmtrtiiitte. By this dillri- butiou, the attendance of the Acadaailh is fecurcd, thofe who are prcfcnt receiving the furplus otherwife intended for the abfeut. To elect or expel a member, at Icall iS are required ; nor can any be chofen unlcfs he petition for it: by this expedient, the affront of refufals from pcrfons elciilcd is avoided. Religious are not admitted ; nor can any noblemen, or perfon of dirtinCtion, be admitted on another footing than as a man of letters. None arc to be expelled, except for bafc and diihonclt pradices ; and there are but two inftances of fuch expulfions, the tirfl of M. Granier forrefufing to return adepofit, the other of the Abbe Furetierefor plagiarifm. Thcdelignof this acade- my was 10 give not only rules, but examples, of good writing. They began with making fpceches on iub- jecls taken at pleafurc, about 20 of which were print- ed. They met with great oppolition from the parlia- ment at their tirft inllitution ; it being two years be- fore the patents granted by the king would be regifter- cd. l"hey have been fcvercly fatyrized, and their (tylc lias been ridiculed as encrvatin'> inftcad of rcHningihc Frijnch language. They are alfo charged with having furfcited the world by (lattery, and hiving cxhaulled all the topics of panegyric in praifc of their founder ; it being a duty incumbent on every member, at his ad- Tuiihon, to make a fpecch in praife of t!ic king, the cardinakthe chancellor Scguier,ai:d the perfon in vvhofe place heiseledcd. The mod remarkable work of this academy is a didionary of the French tongue : which, after jo years fp:nt in fettling the words and phralcs 10 be ufcd in wrilina;, was at lad publiihcd in 1694. The foundati'ni of an Acad-viy fimiUrio tlie aiiovc, has been propofed at Pcteriburgh, by the learned priii- cefs Daflikof: it is to confilt of 60 members. The plan has been approved by the emprcfs, w ho has al- ready given a fund for its fupport and citabliiliment. The Royal Spani/ly Aiadcmy at Madrid held its firft Academlti meeting in July i 71 ?, in the palace of its founder, the |1 duke d'Efcalona. It confillcd at firft of eight acadc- Acxna. mifts, including the duke ; to which number 14 others " ' Were afterwards added, the founder being chofen pre- lidcnt or direftor. In i 714, the king granted them life confirmation and protection. Their device is a cru- cible in the middle of the fire, with this motto, Lim- pia,Fya, y da Efplendor ; " it purities, fixes, and gives brightnefs." The number of members is limited to 24 ; the duke d'Efcalona to be diredor for life, but his fucceflbrs chofen yearly, and the fecrctary to be perpetual. Their objed, as marked out by the royal declaration, was to cultivate and improve the national language : they were to begin with chooling carefully fuch words and phrafes as have been ufcd by the bell Spanifli writers ; noting the low, barbarous, or obfo- lete ones ; and compoling a dictionary wherein thefc may be diftinguilhcd from the former. XII. Academies cf Politics ; as that at Paris, con- fifling of fix pcrfons, w ho met at the Louvre, in the , chamber where the papers relating to foreign affairs were lodged.

Academy is alfo a term for fchools and other femi- iiaries of learning among the Jews, where their rabbins and dodors inftruded their youth in the Hebrew lan- guage, and explained to them the Talmud and the fe- crets of the caballa : Thofe of Tiberias and Babylon have been the nioft noted. The Romans had a kind of military academies, efta- bliihcd in all the cities of Italy, under the name of Canifii Martis. Here the youth were admitted to be trained for war at the public expence. The Greeks, befide academies of this kind, had military profeffors called Tiiclici, who taught all the higher offices of war, &c. &c. Academy is often ufcd to denote a kind of col- legiate feminiry, where youth are inftruded in arts and fciences. There is one inPorlfmouth for teaching navigation, drawing, &c. ; another at Woolwich, for fortification, gunnery, &c. — Bclides thcic, there are numerous academies, efpecially in London, for teach- ing mathematics, languages, writing, accounts, drawing, and other branches of learning.

ACAIIUS, the Tick or Mite, a genus of infedls belonging to the order of aptera, or fuch as have no wings. The acarus has eight legs ; two eyes, one on each fide of the head ; and two jointed tentacula. The female is oviparous. Linnaeus enumerates 35 fpecies ; of which fome arc inhabitants of the earth, ibmc of waters ; fome live on trees, others among ftones, and others on the bodies of other animals, and even under their fkin. The defcription of a few of the moft re- markable will here fufficc. I. The firo, or checfe-mitc, is a very minute fpecics. To the naked eye, thefe mites appear like moving par- ticles of duft : but the microfcope difcovers them to be perfed; animals, having as regular a figure, and per- forming all the funtlions of life as perfeftly, as crea- tures that exceed them many times in bulk. The prin- cipal parts of them are the head, the neck, and the body. The head is fmall in proportion to the body ; and has a fliarp fnout, and a mouth that opens and fliuts like a mole's. They have two fmall eyes, and arc ex- tremely quickfighted ; and when they have been once touched with a pin, you may eafily perceive how cun- ningly they avoid a fecond touch. Their legs are each furnilhed at the extremity with two little claws, with which the animal very nicely takes hold of any thing. The hinder part of the body is plump and bulky ; and ends in an oval form, from which there ilfue out a few exceeding long hairs. Other parts of the body arc alfo befet with thin and long hairs. The males and females are eafily diftinguiflicd in thefe little animals. The females are oviparous, as the loufe and fpider ; and from their eggs the young are hatched in their proper form, without having any change to undergo afterwards. They are, however, when firft hatched, extremely minute ; and, in tlieir growing to their full fize, they eaft their (kins feveral times. Thefe little creatures may be kept alive many months between two concave glarfes, and applied to the microfcope at plea- fure. They are thus often feen tn coiiti, conjoined tail to tail ; and this is performed by an incredibly fwifc motion. Their eggs, in warinwea;hcr, hatch in 12 or 14 days; bat in winter they are much longer. Thefe eggs arc fo fmall, that a regular computation ftiows, that 90 millions of them are not fo large as a i common pigeon's egg *. They are very voracious ani- • Bakir's . mals, and have often been feen to eat one another. iW/Vro/io/*/.

The hinder part of the abdo- men is crenated, the fcuttellum is oval and yellowifli, and the beak is trilid. It is a native of America, and flicks fo faft on the legs of travellers, fucking their blood, that they can hardly be extraifled. 3. The telarius is of a greenilh yellow colour. It has a fniall Uing or weapon, with which it wounds the leaves of plants, andoccafions them to fold backward. They are very frequently to be met with in the autumn, inclofed in the folded leaves of the lime-tree. 4. The exulcerans, or itch-acarus, is a very fmall fpecies : its body is of a rigurc approaching Vj oval, and lobated ; the head is fniall and pointed ; its colour is whitilh, but it has two duiky femicircular lines on the back. It has long fetaceous legs, but the two hrrt are fliort. It is found in the pu fillies of the itch : authors in general have fuppofed that it caufcs that difeafc ; but others obfcrve, that if this were fo, it would be found more univerfally in thofe puftules. It is more proba- ble that thefe only make a proper nidus for it. Sec, however, the article Itch. J. The batatas is of a blood-colour, and a little rough ; the fore pair of legs are as long as the body. It inhabits the potatoes of Surinam. 6. The ovinus, or Ihecp-tick, has a flat body, of a roundifh figure, but fomewhat approaching to oval, and of a yellowilh white colour, and has a fingle large round fpot on tlieback: the anus is vifiblc in the lower part of the body ; the thorax is fcarce confpicuous ; the head is very fmall and black ; the mouth is bifid : the antenna: are of a clavated figure, andof the length of the fuout ; the legs are Ihort and black. It is com- mon onflieep,and its excrements Itain the wool green : it will live in the wool many months after it is ihorn from the animal. 7. Thecoleoptraiorum, or ararus of infefts, is ex- tremely minute : itsbody is round, reddifli, aiidcover- cd with a firm and hardil-cin ; the licad is very fuiall, the neck f'.arcc viliblc ; the legs are maderately long, the anterior pair longer than the others-, it hasawhitt- ntfs about the anus.

ACCKLERATION, ill mechanics, the increafe of velocity in a ir.oving body. Accelerated motion is that wliich continually receives frclh acccfllons of velocity. Acceleration flands dirCL-Uy oppofed 10 rctardat'iot:, which denotes adiminution of velocity. Acceleration is chieHy ufcd in phyfics, in re- fpciit of falling bodies, /. c. of heavy bodies tending to- wards the centre of the earth by the force of gravity. That natural bodies are accelerated in their o'efccnt, is evident from various donfulcrations, both a priori and pcjleriori. — Thus, we aftually find, that the greater height a body falls from, the greater impreflion it makes, and the more vehemently does it flrike the fub- jeft plane, or other obftacle. Various were the fyflems and opinions which philo- fophers produced to account for this acceleration. But the immediate caufe of acceleration is now fufHcicntly obvious; the principle of gravitation, which deter- mines the body to defcend, deter.-nining it to be acce- lerated by a ncccflary confequence. Stippofc a uody let fall from on high : tl;c prin;ary Acali-ra- laufc ofits bcgihiiiugtodcfccnd isdoubtlefs ihcpower •'<">• of gravity ; but when once the dtfcent iscomuunccd, " "' that Hate becomes in fjme meafure natural to the bo- dy J fo that if left to itftlf, it would perfevere in it for ever, even though the fird caufe fiiould ccafe : as we fee in 3 flone calt with the hand, which continues to move a('tcr it is left by the caufe that gave it mo- tion. But, belidc the propenlity to defcend imprelTed by the lird caufe, and v.hich of itftlf were fiiriicient to continue the fame degree of motion, once begun, ;// infittitum ; there is a conltant accclllon of fubfcipicnt efforts of the fame principle, gravity, which continues to aft on lilt body already in motion, \•^. the fame man- ner as if it were at rcil. Here, then, being a double cauic of motion ; and both ailing in the lame direc- tion, viz. dirtftly tow ards th.e centre of the earth ; the motion they jointly produce mu/l nccellarily be greater than that of any one of them And the velocity thus incrcafed having the l".ime caufe of increafe dill per- iilting, the dtfcent mud nccelfarily be continually ac- celerated. The morion of a body afcending, or impelled up- wards, is diminillied or retarded from the fame prin- ciple of gravity, acting in acontrary dircftion, in the fame manner asa falling body is accelerated : See Re- tardation. A body thus projefted upwards, rifes till it has lod all its motion : which it docs in the fame time that a body falling would have acquired a veloci- ty equal to that wherewith the body was thrown up. Hence the fame body thrown up, will rift to the fame height from which fallingit would have acquired the velocity wherewith it was thrown up : And hence the heights which bodies thrown up with different velocities do afcend to, are to one another as the fquares of thofe velocities. jIccelf.r iTios of Bodies of inclined Plains. The fame general law obtains here as in bodies falling perpendi- cularly : the effcftof the plane is to make the motion (lower; but the inclination being every where equal, the retardation ariling therefrom will proceed equally in all parts, at the beginning and at the ending of the motion.

Accelerat:o."j is alfo applied in the ancient aftro- r.omy, in rcfpeft of the lixcd liars. — This acceleration was the difference between the revolution of the /W- mtim mobile and the folar revolution ; which was com- puted at three minutes and 56 feconds. jicczi.tR/mos oj the iMoon, a term ufed to cxprcis the increafe of the moon's mean motion from the fun, compared with the diurnal motion of the earth ; fo that it is now a little fwifter than it was formerly. Dr Hal- ley wasthcfirft who made this difcovcry ; and he was led to it by comparing the ancient cclipfcs obferved at Babylon with thofe obferved by Albatennius in the ninth century, and fomc of his own time. He wai not able to afccrtain the quantity of this acceleration, becaufe the longitudes of Bagdad, Alexandria, and Aleppo, where the o'jfervations were made, had not been A C C { 5i ] A C C Accclera- bceii accurately dctcnni:icJ. Bal ih'.cic his time, tlic tioii longitude of Alcxiiulria has been afcertaiacd by Cha- I zcllcs ; and Babylon, according to Ptolemy's account, Acccndonct jj^.^ ^^. ^.^^ jYoiu Alexandria. From thde data, Mr Dimi liornc com pared fcveril ancient and modern eclip- fcs,wiih the calculations of them, by hisown tables, and lurcby verified Dr IloUcy's opinion ; for he found that the fame tables rcprcfcut the moon's place more back- waril than her true place in ancient etlipfcs, and more forward than her trueplace in later cclipfcs ; and thence jiiflly inferred, that her motion in ancient times was llowcr ; i;i]atcr times (jiiicker, than the tables give it. Cut he did not content himfclf with merely afccrtaiii- iiigthe fait ; he proceeded to determine the quantity of the acceleration ; and by means of the moll ancient cclipfc of which any authentic acco.int remains, ob- fcrved at Babylon in die year before Chrift 721, he concluded, thatthe obfcr\ed beginning of this ecliplc was not above an hour and three-quarters before the beginning by the tables ; and therefore the moon's true place could precede her place by computation but little more than 50' of a degree at that time. Admitting the acceleration to be uniform, and the aggregate of it as a fquare of the time, it will be at the rate of about 10' in 100 years. Dr. Long attributes the acceleration above dcfcribed to one or more of thefe cjufes : cither, t. The annual and diurnal motion of the earth continuing the fame, tlie moon is really carried round the earth with a great- er velocity than heretofore : or, 2. The diurnal motion of the earth, and the periodical revolutions of the moon continuing the fame, the annual motion of the earth round the fun is a little retarded ; which makes the fun's apparent motion in the ecliptic a little llowcr than formerly, and confcqucntly, the moon in palling from any coiijundion with the fun, fpends lefs time before Ihe again overtakes the fun, and forms a fubfc- quent conjuniflion : in both thefe cafes, the motion of the moon from the fun is really accelerated, and the 'fynodical month actually fliortcned. Or, 5. Tlic annual motion of the earth, and the periodical revolution of the moon continuintr the fame, the rotation of the earth round its axis is a little retarded : in this cafe days, hours, minutes, feconds, &Cyby which all periods of time muli be meafurcd, arc of'^a longer duration ; and confequently the fynodical m.outli will appear to be ihortcned, though it really contains the fame quan- tity of abfolute time as it always did. If the quantity of matter in the body of the fun be lelFcned by the particles of light continually dreaming from it, the irotionof the earth round the fun may become llowcr : if the earth increafes in bulk, the motion of the moon round the earth may be quickened thereby.

The draimfltx iHcoit (' or "), iscompofcd oflx'th the acute and the grave, and points out a kind G 2 A C C [ i2 ] A C C Accent, of iinJiilatiou of the voice. The Latins have made the ' ^ fai-ic ufcof tlicl'c three accents. The Hebrews have agrainmatical, a rhetorical, and nui Ileal accent : though the firll and lall feeni, in etfed, lo^bc the fame ; both being comprifcd under the ge- neral n:ime o( Ionic (iccc-i/ii , becaiife they give the pro- per tone to fyllaliles ; as the rhetorical accents are faiJ to be euphonic, bccaufc they tend to make the pronunciation more fweci and agreeable. There arc four euphonic accents, and 25 tonic ; of which feme are placed above, and ollicis below the fyllablcs ; the Hebrew accents fcrving not only to regulate the rilings and fallings of the voice, but alfo to dilliiiguilh the fe^KionSjperiods, and numbers ofperiods,ina difcourfe ; and to anfwcr the fame purpofes with the points in other languages. Their accents are divided into cvj- perors, kings, dukes, ire. each bearing a title anfwer- able to the importance of the dillinction it makes. Their emperor rules over a whole phrafe, and terminates the fcnfe completely ; anfwering to our point. Their king anfwers to our colon ; and their duke to our comma. The king, however, occafionally becomes a duke, and the duke a king, as the phrafesare more or lefs fliort. It mull be noted, by the way, that the management and combination of thefc accents differ in Hebrew poetry from what they arc in profe. The ufc of the to- nic or grammatical accents has been much controver- ted : fomc holding that they diftinguilh the fenfe ; while others maintain that they are only intended to regulate the niulic, orlinging ; alleging that the Jews fmg, rather than read, the fcripturcs in their fyna- • Coi'per, gogucs*. Bc this, liowever, as it will, it is certain the D.im Mo- ancient Hebrews were not acquainted with thcfe ac- cents. The opinion which prevails amonglf the learn- ed, is that they were invented about thefixth century, bythcjewifh doilorsof the fchool of Tiberias, called the M,ilfor:i;s. As to i!ic Greek accents, now fecn both in mann- fcripts and primed books, there has been no lefs dif- pate about- their antiquity and ufe than about thofe of the Hebrews. Ifaac Volfius endeavours to prove them ofmoderninvention ; ailening, that anciently tlicyhad nothing of the kind, bat only a lew notes in their po- etry, which were invented by Ariilophancs the gram- marian, about the time of Ptolemy Philojiater ; and that theic were of mufical, rather than grammatical ufe, ferving as aids in the finging of rheir poems, and very different from thofe introduced afterwards. He alfo Hiowsfrom fcvcral ancient grammarians, that theman- nerof writing the Greek acccntsin thefc days was quite different from that which appears in our books. The au- thor of L'iVl'/ir//i(i// is he who commands, or pro- cures another to commit felony, and is not prelent liim- felf; for if he be prefent, he is a principal. Theyi'- fowi/ is he who receives, alhlls, or comforts any man thath.-.s done murder, or felony, whereof he has know- ledge. A man may be alfo accelTory to an accelFory, by aiding, receiving, &c. an accellbry in felony. An accellbry in felony ihall have judgment of life and member, as well as the principal who did the fe- lony ; but not till the principal be tirll attainted, and convict, or outlawed ihercon. Where the principal is pardoned without attainder, the accellbry cannot be arraigned ; it being a maxim inlaw, Ubs non eli pr'tn- c'lpaiii, iiOH potfjl c[fi: acccjjaniis : but if the principal be pardoned, or have his clergy afler attainder, the ac- cellbry fliall be arraigned ; 4 and 5 \V. ct M. cap. 4. And by llat. i Anne, cap. 9. it is enacted, that where the principal is convicted of felony, orftands mute, or challenges above 20 of the jury, it Ihall be lawful to proceed againft the accellbry in the fame manner as if the principal had been r.ttainted ; and notwith!landir.g fuch principal fliall be admitted to his clergy, pardoned, or delivered before attainder. In forae cafes only, if tlie principal cannot be taken, then the accelfory may be profecuted for a mifdcmeanour, and punilhed by fine, imprifonmcnt, &c. In the lowefl and highcll offences there are noacccflbrics, but all are principals: as in riots, routs, forcible entries, and other trefpall'es, which arc the lowclt offences. So alio in the highcfl offence, which is, according to the Englilh law, high treafon, there are no acccllbrics. Acceflbrics, in petty treafon, murder, and in felonies of fcvcral kinds, arc not to have their clergy. There can be no accellory before the fact in manllaughtcr ; bccaufe that is fuddcn and unprepeiifcd. ylcttssoRr Nerrf , in anatomy, a pair of nerves, v\hich,arilingfrom thcmcduUa in the vertebra; of the ucck, afcendymnJ cuter the Ikull, and pafsoucof it'a- gainwith the par vaguni, wrapped up in the fame Acccflory common integument, and after quitting tlicm, arc di- II ftributed into the inufcles of the neck and Hiouldcrs.

ACCl, (niic. ge'tg.) a town of Tarraconcnfis, for- merly called Altt ; fuppofcd to be Gtianix, to the cafl of the city of Granada, at the foot of a mountain, near the fource of the rivulet Guadalantin ; now greatly de- cayed. It is the Colonia Accitania GemcUa, and was of foinc repute among the Roman colonics. The peo- ple were called Geniellenfes, bccaufe the colony con- lillcd of colonills from the third and lixth legions. ACCIAIOLI (l)onata), a man fanious for his learn- ing and the honourable employments he polfelicd in Florence his native country, in the 15"" century. He wrote, A Latin tranllationoffomeof Plutarch's Lives ; Commentaries 011 Ariltoile's Ethics and Politics ; and the life of Charlemagne. He was fcnt to Prance by the Florentines, to lue for fuccour from Lewis XI. againll Pope Scxius IV. but on his journey died at Milan ; his body was carried to Florence, and buried in the church ot the Cart hulians.Tliefmall fortune he left his children is a proof of his probity and diiinierclled- nefs. His daughters, like thole of Ariliidcs, were married at the public expence, as an acknowledgement of his fcrviccs. His funeral culogium was fpokcn by Chridopher Landini ; and an elegant epitaph, by Poli- tion, was infcribed on his tomb. ACCIDENT, in a general fenfe, denotes any ca- fual accident. Accident, among logicians, is ufed in a tlirccfolJ fenfe. i. \V'hatevtr does not elleniially belong to a thing ; as the clothes a man wears, or the money in his pocket. 2. Such properties in any fubjett as are not clfential to it ; thus whitenefs in paper is an acci- dental quality. 3. In oppolition to fubllance, all qua- lities whatever arc called accidents ; as fwceincfs, foft- * nefs, 6-c. AcciPEN'T, in grammar, implies a property attach- ed to a word, w ithoHt entering into its elfcntial defini- tion ; for every word, notwithitanding iis lignitica- tion, will be either primitive, derivative, liniple, or compound, which are the accidents of words. A word is laid to be priuiiiive, when it is taken from no other word ia the language in wliich it is ufed : thus hcavm, king,gO'jJ, are primitive words. It is faid to be derivative, when it is t.iken from fome other word : \.\m% hiavmlv, kiiigJom, gooJneJ'i, &c. are derivatives. A limplc word is calily dillinguilhcd from a compound : \.\\n& jujt, jujiicc, arc limple words ; unjuft, hijujike, arc compound : r(s is a limple word, as well ispnblua ,- hMrcffuhlica is a compound. Bclidcsthefe accidents, which arc common to all forts of words, each particu- lar fpecies has its accidents : thus the accidents of the noun fubllantive arc the gender, dcclenlion, and num- ber ; and the adjective has another accident, nanuly.ihe coniparifon- See the article Gr a m m a r and L an g u ac e- Acci D F.

AcciDEXTAL Colours, arc ihofc which depend upon the affedions of the eye, in contradiflinflion to thofc which belong to the light itfelf. The iniprcllions made npon the eye by looking Itedfaflly at a particular co- lour, arc various,according toihe fingle colour or com- bination of colours in the object ; and they continue for fonie time after the eye is withdrawn, and give a falfe colouring to oihcr objcds. Mr BufFon has en- deavoured to trace the connedions which thcfe acci- dental colours have with fuch as arc natural, i)i a va- riety ofinflances. The fubjed has alio been coniidered by De la Hire, and M. Epences ; and M. d' Arcy has contrived a machine for determining the duration of the efFeds of light, and after fcvtral trials, finds that it continues about eiglit thirds of a minute. ACCIPENSER, in ichtiiyology, a genus offilhcs belonging to the Ampliibia Nantes of Linnscus. The accipenfcr has a fingle linear noflril : the mouth is in the under part of the head, and contains no teeth ; the cirri are below thcfnout, and before the mouth. There arc three fpeciesof this genus, viz. 1. The rutheiuis has 4 cirri, and i J fquamous pro- tuberances. It is a native of RulTia. 2. The hufohas 4 cirri ; the body is naked, /. e. has no prickles or protuberances. The (kin of the hufo is fo tough and flrong, ihat it is employed for ropes in carls and other wheel-carriages ; and the icjithyo- coUa, or isingi ass of the Ihops, famous as an agglu- linant, and ufed alfo for the fining of wines, is made from its found or fcales. The ancients were acquaint- ed with the fifli tliat afforded this drug. The hufo is the largefl of the genus, and grows to 24 feet in length. Jt inliabits the Danube and the rivers of RufTia. 3. Theftario, or lhirgeon,with 4 cirri and 1 1 fquam- ous protuberances on ihc back. This fifli annually af- cends the rivers in Briiian, but in no great numbers, and is taken by accident in the falmou-nets. Itfccmsa fpiritlefs fiili, inakin"; no manner of relillance when entangled, but is drawn out of the water like alifelefs lump. It is fcldom tsken far out at fea, but frequents •fuch parts as are not remote from the a;ftuarics of great livers. It is admired for the delicacy and firnuicfiof its flelh, which is white as veal, and extremely good when roaO.ed. 1; is generally pickled. A conlidcrable quantity are annually fcnt 10 Britain from America and the Baltic rivers.

Caviare is made of the roes of this, and a!fo of all the other forts of (lurgeons, dried, falted, and pickled up elofe. IchthyocoUa, or ilinglafs, is likcwifc made of the found of this filli, as well as that of the others ; but in \cry fmall quantity. The llurgeoii grows to a great fizc, to the length of 18 feet, and to the weight of 500 pounds. In the manner of breed- ing, this filh is an exception among the cartilaginous kind ; being, like the bony fifli, oviparous, fpawn- iiig in water. ACCII'lTER, tlie name of Linnaeus's firfl order of Birds. See Zoo log v. Among the Romans, the term accipiier li^nified a hawk, and wliich, from its being very carnivorous, they arc conlidered as birds of bad omen ; OJimut accipittem^ quia fcmpcr tiiv'it in armit, OviD. Pliny., however, tells us, that in fomc cafes, parti- cularly in marriage, it was cHeemed a bird of good omen, becaufe it never eats the hearts of other birds ; intimating thereby, that no differences in a married flate ought to reacli the heart. The accipiter was wordiipped as a divinity by the inhabitants of Tcnty- ra, B.n idand in the Nile, being eoniidered by them as the image of the fun ; and hence we find that lumina- ry reprefented, in hieroglyphics, under the figure of a hawk. ACCISMUS, denotes a feigned refufil of fome- tliing which aperfon earnefliy defires. The word is Laiin ; or rather Greek, Axx/»^«c; fuppofed to be form- ed from y^cio, the name of a foolilh old woman noted in antiquity for an affcdation of this kind. ^ccy'nius is fometimes confidered as a virtue ; fomc- timcs as a vice, which Augullas and Tiberius prac- tifed with great fuccefs. Cromwell's refufal of the crown of England may be brought as an inflance of an Accifnuis. AcciSM us is more particularly ufed, in rhetoric, as a fpccies of irony. ACCITUM, (anc. geog.), a town of Hifpania Ba- tica, now Fiii'!a>;a, as appears from an ancient inlcrip- tion ; fitnaic on an eminence of the mountains Alnu- xaras in Granada. ACCIUS (Lucius), a Latin tragic poet, the fon of a frecdman, and, according to St Jerome, born in the confullhip of Hoflilius Mancinus and Attilius Serra- nus, in the year of Rome 583 ; but there appears fomcwhat of confufion and perplexity in this chronolo- gy. He made himfelf known before the deaih of Pa- cuvius, a dramatic piece of his being exhibited tlic fame year that Pacuvius brought one upon the ilage, the latter bciii;!; then eighty years of age, and Accius < nly thirty. NVe do not know the name of thi;; piece of Accius's, but the titles of fevcral of his tragedies are mentioned by various authors. He wrote on the mofl celebrated Itories which had been reprel'cnted on tlic Athenian ftage ; as Andromache, Andromeda, A- trcus, Clytcmnclh-J, Medea, MeIc3gcr,"Phi!ocleres, i5)e A C C [ s Accius, the civil wars of Tlicbcs, 'I'crcus, tlie Troades, &c. Acclama- He iliJ not always, however, take his fubjeds from ''°" the Grecian llory ; tor he coinpofcd one dramatic piece " wholly Roman : it was intitlcJ Brutus, and related to tlic expliilioii of the Tarquins. It is aflirnicd by fume, that he wrote alfo comedies ; which is not unlikely, if he was the author of two pieces, the Wedding and the .Merchant, which have been afcribed to him. He did not conline himfclf to dramatic writing ; for lie left other produL'Hons, particularly his annals, iu<;iuioncd by Macrobius, Prifcian, Keftus, and Nonnius Marcel- lus. He has been ccnfured for writing in too harlli a ftylc, but in all other refpcc^s hasbcencllcemeda very great poet. He was fo much efleemed by the public, that a comedian was puniflied for only mentioning his name on the ftagp. Cicero fpeaks with great deriiion of one Accius who had written a hiftory ; and, as our author had wrote annals, fome inlill that he is the per- Ibn cenfured : but as Cicero himfclf, Horace, (^uinti- lian,Ovid, and Paterculus, have fpokenof our author with fo much applaufe, we cannot thinkit is him whom the Roman orator cenfures with fo much fevcrity. There was alfo in this age a pretty good orator of the fame name, againfl whom Cicero defended Cluen- tius. He was born in Pifeurum, and perhaps was a re- lation of our poet. ACCIUS, a poet of the 16"' century, to whom is attributed A Paraphraf:: of JEfop'i FabUs, on which Julius Scaliger bellows great encomiums. ACCLAMATION, a confufed noife or fliout of joy, by which the public exprcfstheirapplaufe, crtecm, or approbation. Acclamation, in a more proper fenfe, denotes a certain Ibrni of words, uttered with extraordinary ve- liemencc, and in a peculiar tone fomewhat refem- blinga fong, frequent in the ancient afl'emblics. Ac- clamations were ufually accompanied with applaufcs, with which they are fomctimes confounded ; though they ought to be difliuguifl\ed ; as acclamation w as given by the voice, applaufe by the hands ; add, that acclamation was alfo bellowed on pcrfons abfent, ap- plaufe only on thofe prcfent. Acclamation was alfo gived by women, whereas applaufe fccms to have been confined to men. Acclamations are of various kinds; ccclefiiiflical, military, nuptial, fcr.alorial,fynodi a!, fcholaflic, thea- trical, &e. We meet with loud acclamations, nuihcal, and rythmical acclamations; acclamations of joy and refpcfl, and even of reproach and contumely. The former, wherein words of happy omen were iifed, were alfo called Laud.itic>iej, et bona vota, or good willi- es ; the latter, Exccratiott^s et co/ivitia. Suetonius fur- nifliesaninflanceofthis lad kind in theR'iman fcnate, on occalionof the decree for demolifliing ihrftatucsof Domiiian, when the fathers, as the hidorian reprefcnts it, could not refrain from contumelious acclamations of thedeceafed. The like were fliown after the death of Commodus, where the acclamations run in the follow- ing llrain : NoJIi />utri.r honoret dctrahaTitur, piiriiciiiuetonius, who gives another inflance iu the time of Tiberius : a falfe report of Germanicus's recovery be- ing fprcad thrftugh Rome, the people ran in crowds to the capitol with torches and vidlims, linging, Saha Ro/»a, Saha Patrij, italvus ejl Cerviai.wii. — Ncro, jiallionatcly fond of nuuic, took fpecial care to improve and perfect the muiic of acclamations. Charmed with tiie harmony wherewith the Alexandrians, who came to tlie games celebrated at Naples, hadfunghispraifes, he brought fcveral over to inllrucl a number of youth, chofen from among the knights and people, in the dif- ferent kinds of acclamations praclifed at Alexandria. Thefe continued in ufe as long as the reign of Tlico- doric. Hut the people did not always make a finglc chorus; fometimes there were two,w ho anfwered each other alternately : thus, when Nero played on the theatre, Burrhus and Seneca, who were on cither hand, giving the fignal by cLipping, 50CO fcldicrs called Augullals, began to chaut his praifc, which the fpedators were obliged to repeat. The whole was conduced by a mufic mafler called Mcfochorus or /'.>,a it* ; that is, JMany years: wliich Codin exprelles thns, by TO ■J.atxxsiv TO 7rt,>.\/^ft,tn,t, or by TO ToXi/^pov^^Kv J and the \\ ilh or faliitatiou by Troxtp^foKs-M^. And at dinner, the Greeks then prefent v\ilhcd with a lond voice to the emperor and Bradas, Ut Deus aiinos iimltipiuct ; as he tranllates tlie Greek. Plutarch mentions an acclaniu- tion fo loud, upon occafion of Klaminius^s relloring li- berty to Greece, that the very birds fell from heaven wiih the lliout. The Turks praOlife fumething like this on the lij^lu of their emperors and grand viziers to this day. For the acclamations wherewith authors, poets, &c. werereceivcd, who recited their works in public ; it is lobeobferved, the all'embliesfor this purpofc were held with great parade in the moll folcmn places, as the ca- pitol, temples, the Athcnfeuni, and the houfes of great men. Invitations were lent every where, in order to get the greater appearance. The chief care was, that the acclamations might be given with all the order and pomp polliblc. Men of fortune who pretended to wit, kept able applauders in ihtir fervicc, and lent them to their friends. Others endeavoured to gain them by prefeiits and treats, philollratus mentions a young iiian named Vavus, who lent money to the men of let- ters, and forgave the intereil to fuch as applauded his excrcifcs. Thele acclamations were condu6led much after the fame manner as thofe on tlic theatre, both as to the niulic and the accompaniments ; they were to be fuited both to the i'ubjcc^ and to the perfon. There were particular ones for the philofophers, for orators, for hilloriaus, and for potts. ]t would be dillicult to rchcarfe all the forms of them ; one of die moilufnal was io/iAt'J, which was to be repeated three times. Mar- tial comprehends feveral other ufual forms in (his verfe: Craviter, ttto, Nequiter, Etigc, Beati. Neither ths Greeks nor Romans were barren on this head. The names of gods and heroes were given thofe whom they would extol. It was not enough to do it after each head of difcourfc, chieHy after the exordi- um ; but the acclamations were renewed at every tine paliage, frequently at every period. The acclamations wherewidi the fpei51ators honour- ed the v;dorics of the athletx, were a natural confe- qucnce of the impetuous motions which atetndcd tlie gyymaftic games. The cries and acclamations of the people, fomciimcs cxprefling their compaflion and joy, fomttimcs their horror and difgnlt, are flrongly painted by difiercnt poets and orators. Acclamations made alfo a part of the ceremony of marriage. They w-erc ulcd for the omen's fake ; be- ing the L.Tta On4na, fometimts fpokcn of before marriage in Roman writers. Acclamations, at tirft praflifed in the theatre, and palling thence to the fenatc,&c. was in procefsof time received into the acits of councils, and the ordinary af- ftmblies of the church. The people cxpre/lcd their approbation of the preacher varioully ; the more ufual forms were, C*-7/'a.-/o.v.' Tkiri ^.(xiflh, &c. Thefc accla- mations being fometimcs carried to excefs, and often iTiifpliccd, were frequently proliibited by llie ancient Accl;im». dotlors, and at length abrogated ; though they ap- «'»" pear to have been in fome ufe as low as the time of ' St Bernard. ylccLAM ATioK DLulcili, auiong antiquaries, fuch as reprcfcnt the people e.\prclfing their joy inihcpollurc of acclamation. ACCLIVITY, the rife or afcenc of a hill, in oppo- fiiion to the declivity or defcent of it. Sonic writers in fonitieation ufe it for the talus of a rampart. ACCOLA, among the Romans, figniried a perfoii who lived iieur fome place ; in which fcnfe, it differed from ii:c'.4a, the inhnbitai.t of fuch a place. ACCOLADE, a ceremony anciently ufcd in the coufcrrino- of knisrhthood. Antiquaries arc not agreed wherein tlie accolade properly conliUtd. The generality fuppoft it to be the embrace, or kifs, which princes anciently gave the new knight, as a token of their aff'cdion : whence the word accolade; ij. d. a clafping, or taking round the neck. Others will rather have it to be a blow on the chine of the neck, given on the fame occafion. The Accolade is of fome antiquity, in which foever of the twofenfes it be taken. Greg, de Tours writes, that the kings of Krance, even of the firll race, in conferring the gilt Ihoulder-belt, killed the knights on the left cheek. For the acclee, or blow, John of Salilliury allures us, it was in ufeamong the ancient Normans : bythis itw-as that William the Conqueror conferred thehonoiir of knight- hood on his fon Henry. At firft, it was given with the naked fift; but was afterwards changed into a blow with the flat of thefw'ord on the Ihoulderof the knight. ACCOLEE, foaittiraes fynonymous with Acco- lade, which fee. — It is alfo ufed in various fenfes in heraldry : fometimes it is applied to two things joined ; at other times, toaniinals with crowns, or col- lars about their necks, as the lion in the Ogilvy's arms ; and, laftly, to kcws, bations, maces, fwords, &c- j'laced faltierwife behind the lliield. ACCOLTI (Bernardo), fccretiry to the republic of Florence, was furnamed L'Unieo, or the Nonfuch, probably from the great extent of his underftandiuF, tlie variety of fciences he had acquired, and the ex- cellency oi'his poetic vein ; which not only gained him a icat among the academicians of the court of Urbino, but matlc that great Mecx-nas, pope Leo X. in I 520, create him prince of the flate of Nepi. He wrote many pieces; among others, a colleftiou of beau- tiful piicms, primed in Venice in 1519 and 155:?. ACCOMFvlODATlON, the application of one thing, by analogy, to another ; or the making two or more things agree with one another. To know a thing by accotiimijdiition, is to know it by the idea of a limilar thing referred thereto. A prophecy of fcripturc is faid to be fulfilled vari- ous ways ; properly, as when a thing foretold comes to pafs : and improperly, or by way of aec07rimoda- tioti, when an event happens to any place or people, like to what fell out fome time before to another. — Thus, the words of Ifaiah, fpoken totliofe of his own time ; are faid to be fultilled in thofe who lived in our Saviour's ; and are accoininodnted 10 them : " Ye hy- pocrites, well did Ifaias prophecy of you," &c. which fame words St Paul afterv/ards accojwmdata to the Tews of his time.

Spencer maintains, that mod of the rites of the ohl law were an imitation of tliofe of the Gentiles, and particularly of tJie Kg/P- lians ; that God, in order to divert the chiKlrcn of \i- racl from the worlhip they paid to the falfe deities, confccratcd the greatell part of the ceremonies per- formed by thofc idolaters, and had formed out of ilicm a body of tlic ceremonial law ; that he had indeed made fome alterations therein, as barriers agaiull idolatry ; and that he thus accotiiviodated his worlhip to the ge- nius and occaiions of his ancient people. To this condefcenlion of God, according to Spencerf , is ow- ing the origin of the tabernacle, particularly that of the ark. Thcfc opinions, however, have been con- troverted by later writers. ACCOMPANIMENT, fomething attending or added as a circumflance to another, either by way of ornament, or for the fake of fymmctry. Accompaniment, in nuific, denotes ihcinflruraents vhich accompany a voice, in order to fuftain it, as well as to make the nuUic more full. The accompaniment is ufcd in recitative, as well as in fong ; on the ftagc, as well as in the choir, &c. Tlic ancients had likewife their accompaniments on the theatre ; they had even different kinds of inllruments toaccompany the chorus, from thofc which accompanied the aftors in the reci- tation. — The accompaniment, among the moderns, is frequently a different parr or melody from tlic fong it accompanies. It is diiputcd whether it was fo among the ancients. It is generally alleged, that their ac- companiments went no farther than the playing in octave, or in antiphony to the voice. The Abbe Kra- guier, from a palfage in Plato, pretends to prove, that they had adual fymphony, or n\ulic in parts : but his arguments Icem far from being conclufive.

Accretion, among civilians, the property acquired in avagLte or unoccupied thing, by its adhering to or following another already occupied : thus, if a legacy- be left to two perfons,one ofwhom dies before the ttf- tator, the legacy devolves to the furvivor by right of accretion. ACCROCHE, in heraldry, denotes a thing's be- ing hooked with anotlur. ACCUHATION, a pollure of the body, between fitting and lying. The word comes from the Latin Jtv/c /•are, compounded of «o, 1 lie down, y^c- cubatioii, or Accubitin, was the table-pofture of the Greeks and Romans ; whence we lind the words par- ticularly nfe for the ly iiig, or rather (as wc call it) fit- ting down tomcat. The Greeks introduced this pof- ture. The Romans, during the frugal ages of the re- public, were llrangcrs to it : but as luxury got footing, this poflurc came to be adopted, at lead by the men ; for as to women, it was reputed an indecency in them to lie down among the men : though, afterwards, this too was got over. But children did not lie down, nor fervants.nor foldiers, nor ptrfons of meaner condition; but took their meals fitting, as a poflurc lefs indulgent. TheRoman mannerofdifpofingihemfelves at table was this : A low round table was placed in the ccenaculum, or dining-room ; and, about this, ufually three, fonie- tiraesonly two, beds or couches ; according to the num- ber of which, it was called bicltuiuvi or tiicliiiium. Thefe were covered with afort of bed-clothes, richer or plainer according to the quality of the perfon, and furnilhed wi:h quilts and pillows, that the gue lis might lie the more commodioully. There were ufuilly ihrce perfonson eacli bed ; to crowd more, was eflecmed for- did. In eating, they lay down on their leftlides, with their heads refting on the ))illows, or raiher on their elbows. The firll lay at the head of the bed, with his feet extended behind the back of the fecond ; the fccond lay with the back of his head towards the navel of tl.efirft, only feparated by a pillow, his feet behind the back of the third; and lb of the third, or fourth. The middle place was eflecmed the moH honourable. Before they came to table, they changed their clothes, puttingon what they called (nr/Zij/'z/vd veJHs,\.\it dining- garment ; and pulled off their Ihoes, to prevent fouling the couch.

ACEPILALOUS, or AcEPHAtus, in a general fenfe ; without a head. The term is more particularly ufed in fpeakingof certain nations, or people, reprefented by ancient na- turalills and cofmographers, as well as by fonie mo- dern travellers, as formed without heads ; their eyes, mouths, &c. being placed in other parts. Such arp the Blemmyes,a nation of Africa near the head of the Niger, reprefented to be by Pliny and So- linus ; Blemviyes tradunttir capita abi^e, ore et oculis peiiore affixis.

And Suidas, Stcphanus Byzan- tinus, Vopifcus, and others after them, relate the like. Some modern travellers ftill pretend totind acephalous people in America. Several opinions have been framed as to the origin of the fable of the Acephali. The tirft is that of Tho- mas Bartholin, who turns the whole into a metaphor ; being convinced, that the name Acephali was anciently given to fuch as had lefs brain, or conduced themfelves lefsby the rules of prudence, than others. Olearius rather apprehends,that the ancient voyagers, viewing certain barbarous people from the coalts, had been ini- pofed on by their uncouth drefs ; for that the Samo- gitians, being Ihort of ftature, and going in the fcve- rity of winter with their heads covered in hoods, fecni at adiftance asif they were hccdlefs. F. Lafitau fays, that by Acephali are only meant, people whole heads are funk below their Ihouldcrs.

'\ I. The pfeudo-piatanus, or fycamore, is a very large and beautiful tree, with broad leaves, divided into live lobes ferratcd in their edges ; of a dark green colour on the upper fide, but paler and fomewhat hoary un- derneath ; the flowers are very fmall, and of a green- ilh white colour. The corolla of this fpecics is fcarcely diflinguilhable from the calyx, and the fta- mina are long. T he fruit is large, and beautifully variegated with green and purple. This fpecics is a native of Germany, but thrives very well in Great Britain, where it is frequent in plantations. It is very proper for making plantations near the fea, orlhelter- ing Inch as are already too near it ; becaufe the fyca- morc-tree refills the (pray of the ocean much better [han moft other trees. But it has this inconvenience, tiiat its leaves are devoured by iiifeds, foas to become full of holes, and very unfightly : which has caufed the planting of it to be much neglected of late. It has, howe\er, long been conlidcred as a timber tree, having been much ufed by the. turners for wooden bowels, diflies, trenchers, &c. ; but lincc the cuflom of ufmg earthen ware has become fo pre- valent, its value for thofe purpofes has greatly dccrea- fed. There are two varieties ; one with broad leaves and large keys, the other with variegated leaves. By tapping it yields a liquor not unlike that of the birch tree ; from which the highlanders of Scotland forac times make an agreeable and wholefome wine. 1. The campeltris, or common maple, is too well known to need any particular dcfcription, as it grows very frequently in hedge-rows in moft parts of Britain. The timber of the common maple is far fuperior to Acer, the beech tor all the. ufes of the turner. When it tlic abounds with knots, as it frequently docs, it is highly Mai>k--trcei elteemed by joiners for inlay inga. it isalfo irequently * employed tor making niulical inllruments, on account of itslightncfs ; and lor the i\hitenels of its wood was formerly cltcemed for makiug tables, &c. But the principal va!ue of the maple is for underwood ; it be- ing of a quick growth, and affording good fuel. 3. The negundo, or Virginian alli-leaved maple, ij . avery llrongiliooting tree ; and in Virginia, whcreit is a native, is one of the largelt trees of this kind. Its leaves .ire of a pale green, and well adapted to give a variety of tint : but ilanbury fays, that this trcc- ought not to be planted in expofed fituations, the branches litingfubject tobc fplit ott'by the wind. Ita ufcs are limilar to thofe of the fycamore. 4. The platanoides, or Norway-maple, grows na- turally iiiNorway, Sweden, and othernorthern coun- tries of Europe. ]t rifes to a good height, and is well furnilhed with branches with fmooth leaves, of a Ihining green colour, and beautifully indented. Thefc have an acrid milkyjuice, which prcvtnts them from being preyed upon by infefts as the fycamore is ; and as this fpecies relift s the fpray of the fea equally with the firft, it is preferable in plantations fituaicd near the fea. In au- tumn the leaves dye to a golden yellow colour, which caufes a delightful elfec^fc at that feafon when the differ- ent tintsofdecayingvegctablesaredifplayed.The dow- ers are alfo beautiful ; they come out early in the fpring, are of a fine yellow colour, and fliow themfelves to ad- vantagebefore the leaves come out. They are frequent- ly fucceededby keys, which fonietimcsarriveat maturi- ty in Britain. There is a variety with llriped leaves 5. Therubrum, or Virginia fcarlet flowering maple, is a native of that country, and never grows to a large llze in Britain. It is, however, cultivated in gardens for the beauty of its flowers, wliich appear in the be- ginning of April, in roundifli bunches, at the bottom of the footllalksof the leaves. The feeds are ripe in live or (ix weeks after ; and ought to be immediately fown, being othcrwife very apt to pcrifii. The tree ought tobclheltered,efpecially whilft young, from the north-eaft winds ; it delights in a inoill light foil, where it will thrive much better, as well as produce many more flowers and much better feeds, than in a dry ground. A variety of this tree is known in England by the name of SirCharlci Wager's Flowerirg IMaple, from its being firft fent from America to Sir Charles Wager. The flowers of this kind come out in larger clufters than the other, and furround the fmall branch- es, fo that the tree appears entirely covered with them, and makes a much more beautiful appearance than the former, which is now not fo much efleemed. 6. The faccharinum,orfugar-maple,isa large grow- ing tree : will arrive at the height of 40 feet ; and has broad thin leaves, divided into five principal parts ; which are again indented or cut at the edges intofe- veral acute fcgmcnts. Their furface is fmooih, of a lightgrcen colour, whitifli underneath; and they grow on pretty long footllalks. The flowers come out in the fpring, about the time of the Norway maple ; and they are fucceeded by long keys, which fometimes ri- pen in England. In America the inhabitants tap this tree iu.the fpring, boil the liquor, and the feces af- ford ACE [ 6i ] ACE Acer ford a ufcful fugar. The fycamorc, the afli-lcavcd, the and the Norway maples, alfo abound with a faccharine SJaple-trec jiiioe, from which there is no doubt but a afcful fugar *"~^' might be jncpartd. 7. The Fcufylvanicum, or American mountain-ma- ple, very much refemblcs the fugar-maple, only its leaves are ir.orc pointed. 8. The opalus, or Italian maple, is very common in moll parts of Italy, particularly about Rome ; but in Britain is very rarely t j be met with, though hardy enough to bear the open air. It is one of the largcll fpecics of trees in Italy, ?.nd atfords a great fliadc by its numerous and large leaves. On this account it is planted on the road-lidcs, and near habitations. 9. The monfpefulanum, or Montpelier maple, is common in the fouth of France, and in Italy ; but is hardly met with in Britain. The leaves rclcmblc thofc of the common maple ; but are of a much thicker fub- llance, a fliiniug green colour, and not fo large. They continue in verdure very late in the autumn, whicli renders the trees more valuable. 10. The creticum, or Cretan maple, grows natural- ly in the Levant ; it fomewhat refcmbles the la(l fpe- cies ; but its leaves arc of a much thicker texture, and their footllalks covered with a foft hairy down ; where- as thofe of the other arc fmooth and loft. Propagation and ciillure.'\ — I. By/cei/i. The firfl four fpecics arc cafily propagated in this way. The keys, when ripe in aulumn, may be gathered, and in a few days after fown about an inch and an half deep, in beds of common mould. In fpring the plants will ap- pear, and make a flioot of about a foot and an half by the autumn following, if the ground of the femi- nary be tolerably good, and they are kept free from weeds. The fpring after they come up they fliould be planted in the nurfery in rows two feet and an half afunder, and their diftance in the rows mull be one foot and an half. Here they may remain till they are big enough to plant out finally, with no further trouble than taking otf unlightly lide-branches, and fuch as have a tendency to make the tree forked, except digging be- tween the rows, which mufl always be done every winter. For the other fpecics, their feeds, as they do not ripen in this country, ought to be procured froui the places where they naturally grow, and managed in the following manner : A cool ihady part of the femi- nary Ihould be appropriated for the purpofc ; the mould fliould be made tine ; beds (hould l)e marked out four fcctwide, and in length propsrtionable tothecjuantity; and in thefc the feeds fhould be regularly fown, fifting over them about half an inchofthctinefl mould. When the plants come up, they mull be kept clean from weeds, and frequently watered : and this work inull be duly at- tended to all fummer. The next fpring, the ftrongcft may be drawn out, and planted in the nurfery, in rows two feet afunder, and at the dillance of a foot from each other in the rows ; leaving the others in the feminary to gain ftrcjigth. The fpring foilowii;g they alio nuifl receive tlie lame culture ; and in the nurfery they may remain with no other trouble than keeping the ground clian from the weeds in fummer, digging between the rows in the winter, and taking off all flrong and irre- gular fidc-dioots till they arc planted out. Trees railed from feedswill ^row faflcr, and arrive at greater height, than thofc railed from layers: but they will not pro- duce fueh (juaniiiiesof riowers ; which makes the latter Acer, method more eligible for thofc who want thefc plants the for a low Ihrubbery. — Seeds of the variegated kinds al- Maple-tree fo, when lown, will produce variegated pLnts in re- """'' turu : which renders the propagjiion of thefc forts very expeditious where plenty of feeds may be had. Where thefc are not to be obtained, the plants are propagated by budding, as afterwards directed. 2. By/ajerj. All the fpecics may be propagated b/ this inetiiod ; though it is never pradifedfor the com- mon maple and the fycamorc. The young Ihoots may be at any time laid down in the autumn, i^ inter, or early in the fpring. By the autumn following, they will have flruckroot, and become good plants ; when the llrongcll may be let out in the places where they are to remain ; whilll the weakcft may be planted in the nurfery, like the fcedlings, for a year or two, to acquire llrength. :;. By cuttings : which method, however, is chiefly praiitifcd on the alli-lcaved and Norway maples, which more readily take root this way. The cuttings ihould be the bottom parts of the lalt year's Ihoots : They Ihould be taken off early in Odober, and planted in rows in a moill ihady place. The fpring and fummer following, they mult be duly watered as often as dry weather makes it nccelliry, and be kept clean from weeds. By the autumn they will be (it to remove into the nurfery ; though if the cuttings are not planted too clofe, they may remain in their lituation for a year or two longer, and then be fet out finally, without the trouble of being previouliy planted in the nurfery. 4. By iiidJii.g, grafting, and inarching. 1 hefe methods are only praclifed for the variegated forts and the large broad-leaved kind. The latter is to be conti- nued no otherwife than by budding it on llalks of the common fycamorc ; for from the feeds, tho' fo large themfclves, only the common fycamorc is produced. In order to propagate chefe varieties by budding, let Ibme plants of the common fycamorc, one year old, be taken out of the feminavy, and fet in the nurfery in rows a yard afunder, and the plants about a foot and a half dirtance from each other in the rows : Let the ground be kept clean from weeds all fummer, and turned in in the winter ; and the fumnier following the ftocks \\ ill be of a proper lize to receive the buds, which Ihould be taken from the moll bcautifully-ftriped branches. The bell lime for this work is the middle or latter end of Auguft. Having then budded yonr Hocks with the eyes or buds fronting the north, early in Oc- tober takeoff.thc bafs-matting, which before this time will have confined the bark and pinched the bud, but not fo as to hurt it much. Then cut off the ilock jull above the bud, and dig the ground between the rows. The fummer follo\\ing, keep the ground clean from \s eeds ; cut off all natural lide-buds from the ilock as they come out ; and by aulumn, if the land is good, the buds will have Ihot forth, and formed thenifclvcs into trees live or fix feet high. They may be then re- moved into the places where they are deiigned to re- main ; or a few of them only may be drawn out, lea- ving the others to be trained up I'or larger ftandards. Tiie ftriped Norway maple Ihould be budded on flocks of its own kind; for on thefe they take bed, and both kinds are not very liable to run .iway frimi their co- lours.

They prcferved their liberty till trie time of Philip and Alexander : But in the rcrgn of thofe princes, and afterwards, they were eithe!*'(ubjeft to the Macedonians, who had made themfelves maflcrs of Greece, or oppreffed by cruel tyrants. The Achajan commonwealth confiftedoftwelveinconiiderable towns in Peloponncfus. Its firft annals are not marked by any great adion, for they arc not graced with one eminent eharafter. After the death of Alexander, this little republic was a prey to all the evils which flow from po- litical difcord. A zeal for the good of the community was now extinguilhcd: Each town was only attentive to its private intereft. There was no longer any labi- lity in the flatc ; for it changed its maflers with every revolution in Macedonia, Towards the 124''' Olym- piad, about the time when Ptolemy Soter died, and when Pyrrhus invaded Italy, the republic of the A- chccans recovered its old inflitutions and unanimity. The inliabitants of Pata: and Dymse were the tirfl jlTcrtcrs of ancient liberty. The tyrants were baniHi- ed, and the towns again made one commonwealth. A public council was then held, in which affairs of importance were difcullcd and determined. A regiffer was A C H [ 63 ] A C If • l,ib. viii, •ap.

Ma- ny neighbouring towns which admired the conftitution of this republic, founded or. equality, liberty, the love of julHce, and of the public good, were incorporated with the Achasans, and admitted to the full enjoyment of their laws and privileges. — The arms which the Achasans chiefly ufcd were (lings. They were trained to the art from their infancy, by Hinging from a great diflancc, at a circular mark of a moderate circumfe- rence. By long practice they took fo nice an aim, that they were furc, not only to hit their enemies on the head, but on any part of the face they chofc.

ACHj4iMENES, according to Herodotus, was fa- ther of Cambyfes, and grandfather of Cyrus the firfl, king of Perfia. Mofl of the commentators of Horace are of opinion, that the Achxmenes whom that poet mentions, ode xii. of his 2'' book, was one of the Per- llan monarchs: but, if that were true, he mail have reigned before the Medcs fubdued the Pcrflans ; for we do not hear of any king of that name from the time that the Pcrlians founded that great monarchy, which is looked upon as the fccond univerfal one. However this be, the t^\i\\ct y^rclixmaiians is frequently given to the Perlians, in the old Latin poets. AcH jEmenes, fon of Darius I. king of Perfia, and brother of Xerxes, had the government of Egypt bc- ftowed on him, after Xerxes had forced the Egyptians toreturn to theirallegiancc. Hefomctime aftcrcom- nianded the Egyptian fleet in the celebrated expedition which proved fo fatal to all Greece.

The monarchy is hereditary ; and the king ufually maintains a gnard of 100 Seapoys about his palace. According to Mr Marfden, " the grand council of the nation confifts of, the King or Sultan, four Oelooballangs, and tight of a lower degree, who fit on liis right hand, and fixtcen Cajoorai/gi, who fit on his left. At tlie king's feet fits a woman, to whom he mal.es known his pleafurc : by her it is communicated to an eunuch, who fits next to her, and by him to an officer named Cajooraiig Condoiig, who then proclaims it aloud to the alfembly. There arc alfo prefent two other officers, one of whom has the government of the hazar or market, and the o- therthe fuperinteiuiing and carrying into execution the punifliment of criminals.

If the ftranger be in the ftyle of an arabalfador, the royal elephants arc fent down to carry him and his letters to the monarch's prefcnce ; thcfe being firil delivered into the hands of an eunuch, who places them in a filver difh, covered with rich lilk, on the back of the largeft elephant, which is provided with a machine (houdcr) for that purpofe.

The throne was fome ycarsagoof ivory and tortoifefhell, and when the place was governed by queens, a curtain of gauze was hung before it, which did not obflnift the audience, but pre- vented any perfedlview.

On high days (ar:-; ryah) the king goes in great ftatemounted on an elephant richly caparifoned, to the great mofque, preceded by his ooloo- hallar.gs ; who are armed nearly in the Europeanman- ner." The country under the immediate jurifdidfion of Acheen, is divided into three diftri&s, named Duo pooloo A C II [ 65 ] A C H Achfn, po'jloo duo, Duo l^coloo lecmo, ix\iDu(, Jooko anam. Aclicl'juj. Each dJArid is governed hy a Paiiglccnio, and under ^~"~ him an Imaum and four Pangccchcs to each mofijuc. " Aclicii has ever been remarkable ibr the fcvcrity with which crimes are punilhed by their laws ; the fame rigour Hill fubfills, and there is no commutation admitted, as is regularly edabliOicd in the foutlicrn countries. Tlicrcis great rcafon, however, toconcludc that tlic poor alone cxj'erience the rod of ju/licc ; the nobles being fccurc from retribution in the number of their dependents. Petty theft is punilhed by fufpcnd- ing the criminal from a tree, with a gun or heavy weight tied to his feet ; or by cutting otf a finger, a hand, or leg, according to the nature of the theft. Many of thefe mutilated and wretched objeds are daily to be fecn in the Itrccts. Robbery on thehigliway and houfe-breakingare punilhed by drowning, and after- wards expoling the body on a llake for a few days. If the robbery is coniniittcd upon an imtum or pricll, the facrilcgeis expiated by burning the criminal alive. A man whois convidcd of adultery is feldom attempted to befcrecncd byhis friends, but is delivered up to the friends and relations of the injured hulband. Thefe take him to feme large pbiin, and forming themfelves in a circle, place him in the middle. A large weapon called a Cadoohoiig, is then delivered to him by one of his family ; and if he can force his way through thofc who furround him, and make his cfcape, he is not liable to further profecution ; but it commonly happens that he is infl.-intly cut to pieces. In this cafe Iiis re- lations bury him as tliey would do a buffalo, refufing to admit the corpfe into their houfe, or to perform any funeral rites." Thefe difcouragcments to vice might fcem to bcfpcak a moral and virtuous people : yet all travellers agree in rcprcfcntiug the Achencfeasonc of the nioll dilhoned and flagitious nations of the Kaft. Achen was vilited by the Portuguefe in 1509, only 12 years after they had difcovercd the palfage to the Eaft-Indies by the Cape of Good Hope. They made various attemptstoeftablilh themfelves in the country, but were expelled with difgrace. Sec Sitmmatra. ACHELOUS, in fabulous hiftory, wrcllled with Hercules, for no lefs a prize than Deianira, daughter to king Ocnus : but as Achclous had the power of af- fumingall fliapes, the contert was long dubious : at lail, as he took that of a bull, Hercules tore off one of his horns ; fo that he was forced to fubmit, and to redeem it by giving the conquerfu- the horn of Amalthea, the fame with the Cornucopia or horn of plenty ; wiiich Hercules having iilled with a variety of truits, confc- crated to Jupiter. Some explain this fable, by faying, That Achelous is a w inding river of Greece, whole ftream was fo rapid, that it roared like a bull, and over- flowed its banks ; but Hercules, 1-y bringing it into two channels, broke off one of the liorui-, and fo reftorcd plenty to the country.

The cpilUe attributed to St Barnabas ; The works of Lanfrank, archbiihop of Canterbury ; A collcfiion of fcarce and curious pieces, under the title of Spicilcgium, i.e. Gleanings, in thirteen vo- lumes, quarto. The prefaces and notes, which he an- nexed to many of thefe pieces, Ihow him to have been a man of genius and abilities. He had alio fonic iharc in the pieces inferted in the lirft volumes of Theafts of the faints of the order of St Bennct ; the title whereof acquaints us that they were collcded and publilhcd by him and father Mabillon. After a very retired life, till the age of 73, he died at Paris the 29th of April, 1685, in the abbey of St Germain in the helds, where he had been librarian.

There are 20 fpccies, of which the following are the principal : i. The niil- lifolium, or common yarrow, is found naturally on banks, and by the fides of foot-paths, in nioft parts of Kngland. It moll commonly bears white flowers, though a variety of it is found which bears purple ones. Thefe, however, do not long continue to bear flowers of this colour, if tranfplanted into gardens. It was formerly ufcdin medicine ; but though itmay fiill have a place in foine difpenfatorics, nophyfician of any note cxpeds any virtue from it, or ever prefcribes it. It creeps greatly by its roots, and aUo multiplies by the feeds, fo that it becomes a troubleforae weed where it is once all>^wed to get a footing. The cultivation of it is recommended by Mr Andcrfon, in his Eflays on A- griculture, as a jiropcr food for cattle. This fpccies was the proper achillaja of the ancients, fo named from Achilles ; who,having been the difcipleof Chiron, firfl brought it into ufe for the cure of wounds and ulcers. 2. The fant<>lina,or eallcrn fueezcwort, isfometimes cultivated in gardens; it has large yellow flowers, which ftand upon pretty long footilalks jilaced fingly,- not in bunches as in the common kind. It has leaves like lavender-cotton, which, when rubbed, emitaflrongoily odour. The flowers appear in Juneajid July. ;;. The tomentofa, or woolly varrow, is a native of the fouth of France and Spain, b-it lives in the open air in England. The flowers are of a bri;zht yellow, and continue long in beauty, growing in cluftcrs at the top of the flalks, which feldom rife above a foot high. The leaves arc finely cut, and very hoary. 4. The abrotanifolia, or tall eaftern yarrow, is a native of theiflands in the Ar- chipelago: it grows to the height of two feet and a half, with large umbels of yellow flowers on the top ; the leaves refemble ihofe of the common wormwood, and arc cut into long narrow fegmcnts. 5. The cla- venna, or Alpir.e umbelliferous wormwooj, takes its AchilJata. name from the mountains of which it is a native. It — v'— frldom grows above iix or feven inches in height ; it fupports umbels of white flowers, like thofe of the commwn fneezcwort, which appear in .April and May. The leaves are lilvery, and (hapcd like thofe of worm- wood, which often decay in the autumn and winter. 6. The tanacctifulia, or eaflern fneezcwort, with tan- fey leaves, is a very humble plant, feldom rtling above fix inches in height. The flowers arc nearly as large as thofe of the common fneezcwort, white, and grow- ing in flat umbels. They appear in June and July. Tlie leaves of the plant have fome liktuefs to thofe of the common wormwood, are very hoary, grow clofe to the ground, and decay in autumn fo as to make little appearance in winter. Like the lafl fpccies, this is a native of the Alps. 7. Tiic agcratum, or fwcct maud- lin, was formerly much ulcd in medicine and forculi- nary purpofcs, but has now fallen fo much into neg- lect as to be totally unknown in tlie markets ; fo that when it is demanded, the while maudlin is fubflitutcd initsflcad. The rcafon of this fiibflitution \j'as, that the latter is more hardy and eafily propagated than the fwcct maudlin, which is apt toi'ot in wet winters. The common maudlin flov\ersinJunc and July, and the feeds are ripe in September. 8. The Egyptiaca, or hoary fneezcwort, is a native of the Archipelago. It hatli very hoary leaves, which remain all the year ; and the plants growing clofe and low, make a pretty ap- pearance at all feafons. The flowers are yellow, and are produced in umbels on the top of the flalks ; they appear in June, and continue till the end of Septem- ber. 9. The ptarmica, or common fneezcwort, grows wild in the woods, and other lliady places, in many parts of England ; fo is not admitted into gardens. There is a variety, however, with double flowers, which is preferved in gardens, and is commonly known by the na.mc o{ doril>le maiiil/in. This fpccies creeps greatly by the roots, fo as foon to overfpread a large fpot of ground. If planted in pots, fo as to confine its roots from creeping, the flalks grow clofe together, and make a tolerable appearance when in flower ; but when at a diflancc, fo that the roots have full liberty to run, the flowers appear but indifTerently. 10. The macrophylla, or Alpine fneezcwort, with fewer leaves, is a native of the Alps. It produces many flalks riling near three feet high ; having loofe branching umbels of white flowers on theirtop, refembling thofe of the common fneezcwort, but larger. 11. The na- na, or hoary Alpine milfoil, is likewife a nativeof the Alps; the leaves are hoary, and the umbels of its flow- ers arc moreconipaifl than the former ; the flalks do not rife m.ore than a foot high. 12. The nobilis, or fweet milfoil, approaches to the nature of the common mil- foil; but its leaves are of a paler green, and are nei- ther fo long nor fo mucji cut ofFas thofe of the commoa milfoil are : they have a flrong fweet fcent when brui- fed. 1 3. The alpina, or white maudlin, bears fomc re- femblance to the common fneezcwort; but the leaves arc longer, of a deeper green colour, and deeply in- dented in their edges ; the flowers are white, and the roots creep far under g'round. The plant will rife, in good land, to the height of four feet. Cri.'ttne. All the forts of yarrow arc eafily propa- gated by feeds, which maybe fown either in the fpring- A C H [ 67 ] A C II AcViiUcii, or autumn upon ?. bed of common earth. When ilic Aciiillc?. plants come up, and are ftrong enough lor traiifplsut- * -^~^ i;ig, they /lioi.ild be planted in beds in tiie nurlcry, where they niaycoiitinuetillautmnii,when ihcy Uiould be iraiifplantcd to the places where they arc to remain. The Archipelago kinds, however, are often deftroycd by fevcre froll ; fo they ought to be fiicltcrcd during the winter. Thefe kinds alio rarely bring their feeds to pcrfedlion in Lngland ; they arc therefore to be propagated by flips, wliicli may be taken off and plant- cil in a Ihady border .-iny time in fumnicr, when they will take root in about fix weeks, and then may be trunfplanted where tkcy are to remain. ACHILLEID, AcHii.r.E IS, a celebrated poem of Statins, in which thai author propofcd to deliver the whole life and exploitsof Achilles; bin being prevent- ed by death, he has only treated of the infancy and c- ducatlon of this hero. Sec SrArius. ACHILLES, one of the greatefl heroes of ancient Greece, was the fon of I'cleus and Thetis. He W'lS a native of Pythia, in Thelfaly .

She dipped hiin alfo in the waters of the river Styx ; by which his whole body became invulnerable, except that part of his heel by which llie held him. But this opinion is not univerfal, nor is it a part of his charac- ter as drawn by Homer; for in the Iliad (B. xxi. 161.) he was aftually wounded in the right arm, by the lance of Afleropaut, in the battle near the river Scamander. Thetis afterwards enirulledhim tothecarc of the een- fanr Cliiron, w ho, to give him the flrength necelfary for martial toil, fed him with honey and the marrow of lions and wild boars. To prevent his going to the (lege of Troy, fhe difguifed him in female apparel, and hid him among the maidens at iTie court of king Lycomedes : but Lilylles difcovering him, perfuaded him to follow thcGreeks. .Achilles diftinguilhed hini- felf by a number of heroic aiflions at the liege. Briiig difgufled, however, with Agamemnon for the lofs of Brifeis, he retired from the camp. But returning to avenge the death of his friend Patroclus, he llcw Hec- tor, faftcncd his corps to his chariot, and dragged it round the walls of Troy. At lall Paris, the brother of Heflor, wounded him in the heel with an arrow, while he was in the temple treating about hiimarriagc with Philoxena, daughter to king Priam. Of this wound he died, and was interred on tlie promontory of Sigjsniii ; and after Troy was taken, the Greeks facri- ticed Pliiloxena on his tomb, in obedience to his dc fire, that lie might enjoy her company in the Elylian HtUis. It is faid iliat Alexander, feeing his tomb, honoured it by placing a crown upon it ; at the fame time cry- ing out, that '*■ Achillss was happy in having, during his life, fnch a friind as Patroclus ; and, after his death, a poet like Homer."

Jovius, who knew Achillini, and heard his Icclures, fays, that he was a man of fuch ex- ceeding limplicity, and fo unacquainted with addrcfs and flattery, that he was a laughing-ftock to the pert and fancy young fcholars, although elleemedon account of his learning. He wrote feveral pieces on philofo- phical fubje(5ls, which he publilhcd, and dedicated to John Bentivogli. Achillini (Claudius), grandfon of the former, read Icdlures at Bologna, Ferrara, and Parma ; where he was reputed a great philofopher, a learned divine, an excellent lawyer, an eloquent orator, a good mathe- matician, and an elegant poet. He accompanied Car- dinal Ludovino, who went as legate into Piedmont; but being afterward negledcd by this cardinal, when he became pope under the name of Gregory XV. he left Rome indifguft,and retired to Parma ; where the duke appointed him profellbrof law, with a good falary. He publilhcd a volume of Latin Letters, and another of Italian poems, which gained him great reputation : he died in 1640, aged 66.

ACHYRANTHES, in botany, a genus of the pen- tandria order, belonging to the monogynia clafs of plants, and aflbciating with the Mifeellanex, in the 54ih Natural Order. The characters are : Tlie calyr is a double peri- antliium ; the exterior one conliftiug of three lan- ced acute leaves, which are pcriillent ; the iiitcrior of five leaves, alfo perfiflent. No corolla : The ne Clarinm isfive-valvcd furronnding thegermen, bearded at the top, concave, and falling oH". The /fami'ia confift of five filaments the length of the corolla, the antherx arc ovate and incumbent. The pijlillum has a top- ihaped germcn the flylus is filiform, and the length of the ftamina ; the ftigma is villous, and divided into two fegments. The ferianthiuvt is a rouHdilh one- celled capfulc, not gaping. The feed is fingle and ob- long. Of this genus eight fpecies are cnuoicrated ; but the character of the genus docs not agree in them all. The fpecies are all natives of ihe Indies. Only one of them, the amai'anchus, is conimouly cultivated iu botanical gardens, and that more for the fake of va- riety than beauty. It grows to the height of three fett, with oblong pointed leaves. The flowers come out in long fpikc s from the extremities of the branches, and appear in July, the feeds ripening in September. Plants of this kind inull be reared in a hot-bed, and may be tranfplantcd when they have acquired fufHci- ent Itrength. If kept in pots, and (helicred during the winter in a warm grecn-houfc, they will live two or three years. ACICANTHER.^, in botany, the trivial name of a fpecics of Rhexi a.

ACIDALIUS (Valcns) would, in all probability, have been one of the grcateit critics in thefe latter a- ges, had he lived longer to perfect thofe talents which nature had given him. He was born at Witftock, in Brandenburg ; and having vifitcd feveral academics in Germany, Italy, and other countries, where he was greatly elleemcd, he afterwards lookup his refidcncc at Brcilaw, the metropolis of Silelia. Here he remain- ed a confiderable lime, in expectation of fome employ- ment ; but notliing offering, he turned Roman-Catho- tic, and was chofen rector of a fchool at NielFa. It is related, tliat about four mouths after, as he was fol- lowing a proceflion of the hoil, he was feized with a fudden phrcnzy, and being carried home, expired in a very fhort time. But Thuanus tells us, that his ex- ccliivc application to fludy was the occalion of his un- timely death : and that his litting up a-nights in compo- fing ins conjectures on Plautus, brought upon him a diftemper which carried him off in three days, on the 25"" of May 159J, beingjuiliurnedof 28. He wrote a Commentary on Qiiintus Curtius ; alfo, Notes on Ta- citus, on the twelve Panegyrics ; belidcs fpeeches, let- ters, and poems. His poetical pieces are infcrted in the /)<'//£/> of the German poets; and confiH of epic verfcs,odcs, and epigrams. A little piece, printed in I 59;, under the title of Mulisrts non efft homintis, " That women were not of tlie human fpecies," was filfcly afcribed to him. But the fact was, that .'\cida- lius happening to meet with the manufcript, and think- ing it very whimlicjl, tranfcribed it, and gave it to the bookfeller,w ho printed it. The peribrm.incc was high- ly txclairocd againfl, infomuch that the bookfeller be- ing feized, he difcovered the pcifon who gave him the maniifcript,anda terrible outcry wasniadeagainA Aci- dalius. A itory goes, that being one day to dine at a friend's houfe, there happened to be feveral ladies at table ; who fuppofing iiim to be the author, were mo- ved with fo much indignation, that they threatened to throw their plates at his head, .^cidalius, however, in- genioudy diverted their wrath.

On the other hand, ihe flrong acids of vitriol, nitre, and even fea-falt, arc altogether raullic, and cannot be tailed until they have been largely diluted with water. 2. With water they combine intoa fluid, the fpeciiic gravity of which isnot a mcdiiini betwixt the w.uer and acid fcparately taken. This holds good with the Ihong acids, which grow hot with water, and Ihriuk into lei's bulk by reafon of their emitting a nuaniity of the fire they contain: but whe- ther it alio t^kes place in the weaker acids, bus not yet been afcertaincd ; though the probability is, that it will take place in them alfo. -i.. VN'ith fpirit of w iiie, they unite in to a very xolatileand inflammable fubllance cal- led ethtr. This mult alfo be undcrllood only of the llrong mineral acids, or of the acetous when very much concentrated ; for the acids of tartar, borax, arfenic, lapis ponderofus (tuitgjhn), and molybdsena, do not produce any. 4. They change the blue colour of ve- getables to red, and heighten the colourofthofe which arc already red. — This property is moreuniverfal than thofe we have yet mentioned ; but the volitile fiilphu- reousaeid, thofe of tungilen and niolybdasna, are excep- tions. 5. They unite with all kinds of earths except- ing the filiceous (though the fluor acid diilblvcs this alfo), with fixed and volatile alkalies, and with metals, in fuch a manner as to form compounds conliderably permanent, and whofc ingredients cannot be fcparated without fomedifliculiy. This is the moftunivcrfalanJ didinguilhing mark ; and there is not any acid but what Ihows its attraflion for one or more of thefc fubllanccs, cfpccially the alkaline falts. Oilband fats, indeed, will unite wiih alkalies ; but they may be fcparated by the weakeft known acids, fo that there is no danger of confounding the two together. 6. When mixed with any fermentable liquor, they prevent that proccfs from taking place : or, if it has already begun, they w'lll pat a (lop to it. This alfo nuifl be undcrllood only of the ftronger acids, or at leafl will require a conliderable «iuantity of the weaker to cffeft it. 7- They cannot be frozen but in a degree of cold below the freezing point of water. This property is likcwife not univer- fal, but is remarkable only in the flronger acids. The nature of acids has long been a matter of fpe- culation, and of late has engaged the attention of phi- lofophcrs very conliderably. Some have fuppofed them to be funple chemical elements, while others imagined them to be compofed of water and earth. Both ti-.efeopinions, however, arc inadmifllble ; the former, becaufe we are certain that mofl acids may be entirely decompofed, and refolvcd into aerial vapours of diifer- ent kinds, which could not happen if they were limple and unchangeable elements ; the latter, becaufe there is not the fmalleft probability that two ingredients, feemingly fo iniipid and inadive as water and earth could by their union produce a compound endowed Of the na- ture of a- .cids. with fuch powerf il and even dcllruclivc properties as many of the acids polfefs.— — The late difcovc- ries concerning air of different kinds have iuggelkd a new theory, lirll publilhcd by M. Lavoider, anJ Ihe- iHionlly maintained by the Kreiifh chemills, viz. That the acid principle is contained in the air ; and, accor- ding as it con-ibincs itfelf with different fubllances, forms acids of ditfercnt denominations. This theory be conliders as cllablilhcd by numerous indifputalile experiments. Thcfc cannot here be de- tailed ; but his conclulions from the whole are. That " dephJogiJticated air enters as a conllituent part into the compoiitioH of feveral acids, particularly the phof- phoric, vitriolic, and nitrous ; that this pure and high- ly refpirable air is the conflilutive principle of acidity common to all acids ; and that the difference by which they are diAing-'.llied from each other is produced by the union of one or more principles bclidcs this air, fo as to conflitute the particular form under which each acid appears." To dephlogillicated air in its flate of fixity, therefore, he gives the title of the aci- difying or oxygenous principle ; and concludes farther from his experiments, i." That, whencombined with the matter of fire, heat, and light, this principle pro- duces dephlogillicated air ; though he conliders this pofition as not capable of abfolute demonllration. It mail not, therefore, be confounded with the follow- ing ; which, he lays, are fupported by experiment and politive proofs. 2. That the fame acidifying principle, combined with phlogillic fubllanccs or charcoal, forms fixed air. 3. That with fulphur it forms vitriolic acid. 4. That with nitrous air it forms nitrous acid. 5. That with Knnckel's phofphorus, it forms the phofphoric acid. 6. With fugar it forms the acid of fugar," 6cc. The opinion of Mr Lavoificr concerning the com- pofition of acids has in part been adopted by Mr Kir- wan ; who, in his treatife on Phlogillon, publilhed in J 78 7, informs us that he is now of opinion " that de- phlogillicated air becomes an elfential conflituent part ofacids. All acids (he adds) confill of two principles : one peculiar to each, which, in the opinion of thcan- tiphlogiftians, has not as yet been decompofed, and confequently mull be looked upon, relative to the pre- fent liate of our knowledge, as a limple fubflance : the other, pure air, in a concrete ftate ; that is, de- prived of the greater part of its fpecific heat, and con- denfed into a fmall volume. The firllthey call the acid hajis ; the lall, the oxygenous principle: thus the vitriolic acid, according to them, conlifts of fulphur as its bafis, and pure air in a concrete (late as its aci- difying or oxygenous principle. This doctrine of the compofition ofacids has been admitted by fome of the ablefl defenders of phlogillon, and particularly by thai dillingnifliedphilofophicchemillM. de Morveau, « ith this lingle modification, that the bafes of acids contain phlogillon, which they lofe on uniting to pure air : yet it feems very difficult to conceive how pure air can unite to phlogillon, a fubllancc to which it has the greateft affinity, without forming a new compound en- dowed with very different properties from thofe which itpolTeflcd beforefuch union. It fcems therefore more reafonable to conclude, either that it forms water, as Mr Cavendiih thinks ;or fixed air, as I lliall afterwarf dc- phlogifti- catcd air fuppofed to be the acid principle. Mr Kir- wan'sopi- A C I [ V J A C I Acids, Kirwari firftitarcs die opinion of the diuij)Iil'jgi(lians, — '■ viz.

" Inniyopi- nion (fays he), it conliitsof a bafis or radical principle, Mhich, when fatnrated with phlogillon, conflitutcs ful- phur ; when faturated with hxedair, becomes common fixed vitriolic acid; and, when combined partly with the one and partly with tlie other, becomes volatile vitri- olic acid. That fulphur, during its converliuii into vi- triolic acidjUnitcs to air of fome i'ort or other, is evident from the quantity of air which it abrorl)S, in whatever way that converfion is brought about. 1 hus, Hrfl, du- ring combuflion in refpirablc air, loo grains of fulphur abforb 420 cubic inches ofpurc air, or about 143 grains : gillicated air, phlogiilicatedair, and inflammable air, all in their concrete ftate. " Red, yellow, green, and blue nitrons acids, when thofe coloursarc intcnfe, owe their origin to the abforption of nitrous air; and confequently the pro- portion of their principles is variable, though all have. the dephlogillicatcd acid for their ground. Thus Dr Pricftley, having expofedllrongpale-ytllownitrous acid, whofc fpccinc gravity could not be lefs than 1.400 to nitrous air, found thit loo grains of this acidabforbcd, in two days, 247 cubic inchesof nitrous air: now, loograinsofthisfpiri: mull have contain- ed, by my calculation, about 21 grains of dry acid, and thcfe 21 grains took up 9i.:9 grains of nitrous air. When about 20 cubic inches of nitrous air were abforbed(thatis, about fcvcn grains), the acid became ..AciJ^ but the proportion of this pure air united with a_given of an orange colour ; when 50 cubic inches were ab quantity of fulphur is not calily determined, becaufe it is vitriolic air thatisconllantly formed ; and this air ellentially contains fome portionof fulphur in folution, wliicli portion is variable. Secondly, Pyrites, during thcirdecompolition, abforba confiderableproportionof pure air, as Mr Lavoifier has obftrvco : fo alfo does liver of fulphur expofed to the atmofphere, for after fome time it is converted into tartar vitriolate." Mr Kirwan next proceeds to inquire, whether the pure air all. air abforbed during the combuflion of fulphur continues forbed in to be pure air ; or whether it be converted into water thcburnin^' or iixcd air ? He inclines to the latter opinions, for va- of fulphur j.jp|,5 reafons * which he fpecifies. With regard to the nitrous acid, the experiments of MrCavendini,aswelIasof the French chemifts, leave 6 Whether continues to he fo. p. 29. forbed (about 18 grains) it became green ; and when nearly the whole was abforbed, it evaporated in tlie form of nitrous vapour, carrying oft" part of the wa- ter with it. Hence we fee, that nitrous vapour con- firts of nitrous acid united to three or four times its weight of nitrous air and a little water." Mr Kirwan next proceed to contcfl Mr Lavoificr's Mr Laroi- opinicn, th at nitrous air is a conflituent principle of the ficr'stheory nitrous acid. " The following experiments (fays he) contcfted. Ihow that nitrous air is not a conrtituent principle of the nitrous acid, but that fixed air is. i. There is not a doubt but that pure nitrous acid enters en tire, and with- out deconipofition, into lixcd alkalis, and forms nitre. Now if nitre be diftilled in a good earthen retort, it will be wholly decompofcd ; and fo alfo will the acid no room to doubt that it is produced during the defla- itfelf, except a few drops which pais in the beginning Formation of the ni- trous acid. gration of dephlogifticated and inrtammable air. Mr Cavendifli has fliown that the nitrous acid may be formed by taking the electric fpark in a mixture of three rncafurcs of plilogirticatcd air and fcven ofdc^ phlogilHcated air, or, in weight, one part of the for- mer and about 2.6 of the latter. Mr Lavoifier, as has been already mentioned, fuppofcs the nitrous acid to be compofed of nitrous air united to the oxygenous principle, or balisof pure air ; and 100 grains of dry of the dilliilatioii, and nothing but dephlogiilicated air, more or lefs pure, and confequently intermixed with phlogiJlicated air and a (light proportion of tixed air, will be found : thefe, there lore, are its true confli- tuent parts when difcngaged from fubllancesthat can- not communicate phlogilton to it in any remarkable quantity, fuch as alkali^;s and earths; butifit be fepara- tcd from fubllancesthat contain phlogiilon, fuch as me- tals, it will then indeed be refolved into iiurous air and I'roportjon ni its coD- Hitucuc p^rts. nitrous acid confill of 64 grains of nitrous air united dcphlogiilicated air more or lefs pure, the phlogirton to ;6 of pure air deprived of its fpecitic fire ; or, ac- of the fixed air being detained by the metal. Mr Bcr- cording to Mr Kirwan's calculation, 1 73 cubic inches thollet, who fcems to have made the experiment with of nitrous air and loj of pure air. But nitrous air, thegreatefl exa^lncfs, produced 7i4cubic inchesof dc- as Mr Lavoil'ier himfelf has obfervcd, is a compound ; phlogifticatcd air from a troy ounce of nitre.' This, 100 giains of ir, according to him, containing 32 cf however, was far from being of the purefl kind ; and phlogifticated and 68 of pure air; confequcmly 64 Dr Prielllcy, Mr Berthollct, and Mr Succow, obferv- grains of it contain 20.5 of phlogirticated air, and ved, that the air which tirfl palles contains fixed air 4^5 of pure air. Hence, according to him, 100 and renders lime-water turbid. Here then we have grains of dry nitrous acid contain 79; of pure air and three of the conrtituent partsof the nitrous acid, with 20; of phlogifticated air. Mr Kirwati is of opinion fcarce any nitrous air ; which the antiphlogiflians fup. that too grains of pure, dry, and colourlcfs nitrous pofe to be one of the conllituent parts of the acid, and acid contain 58.1 7 grains of hxcd air as its acidifying to make two thirds of its bulk when exhibited in an principle, 57.0') of nitrous balls, and 4.77of jihlogiflon aerial frrm. united to the nitrous bafis. With regard to the nitrous To obviate an obje(flion that the quantity of fixed bafis itfelf, he fays that one third of its weight is air thus obtained is too fmall to dcfcrve to be ranked phlogifticated and two thirds dephlogifticated air, among the cotuiiiuent [lartsofthe nitrous acid, Mr both in a concrete flate. Kirwan firft inquires in what proportion it ought to " Nitrous bafis (fays Mr Kirwan), faturated with exift tliere ; and though this is variable, according to phlogiilon, conftitutcs nitrons air : 1^0 grai.'s of this the different ftates of the, nitrous acid with refpcct to bafis take up nearly 22 of phlogifton. Hence the con- phlogiftication, he reckons it at one-third of the acid /liiucnt principles of nitrousacid arc fixed air, dephlo- as exjfting in the nitre ; and, from the dccompofitioii of ihu.

Asa prool" that fixed air may be dccompcfcd in this man- ner, he adduces two expcririuiits or iJr PrielUcy. In oncofthefcjdcphlogiflicatcd air was obtained by means el" acetous acid in that concentrated Itatc in which it is called radicut liuegar. Raving mixed half an ounce of the acid with two ounces of calcined whiting, he obtained from it 350 ounce-r.ieafiires of air ; of which about one third was fixed more in the firll portion, and Ids in the lall. The ftandard of the refiduum in the firll portion was, 1.66, in the fecond, 1.42, and in the third, 1.38; wliich is very near the goodnefsof common air. The whiting then weighed 760 grains. On adding a quarter of an ounce more of radical vine- gar, and repeating the operation, 1 20ounce-meafures of air were obtained, and the whiting was reduced to 750 grains. A third operation, in which another quar- tcrof an ounce of vinegar was added, reduced the mat- ter to 489grains : but thelafl portion of air extracted had no fixed air, and was confiderably better than that of the atmofphtre. The other experiment was laadc with linie-llone alone ; from four ounces of the lahit.- cry flats, of which830ounce-nieafures ofair were obtained, the tint portion of which had only one- fourth of fixed air, and the ftandard of the refiduum was never better than 1.56, nor worfe than 1.66 ; fo that it was nearly of (he goodncfs of common air. Our author then proceeds to relate feveral other ex- periments in which the nitrous acid was decompofed ; but a particular relation of them would fwell this ar- ticle beyond its due bounds. At lad, however, he concludes in the following manner. " If fpirit of nitre be made to boil, and its vapour received through a red-hot earthen tube, it will be converted into de- phlogillicated air, in which a portion both of phlogi- fiicated and fixed air is found, as Dr Pricflley has dif- covered : the water through which this air pilfes will alfo contain fixed air. Here then are feveral ways of liecompoilng the nitrous acid ; and in one only it is refolved into nitrous and dephlogiilicated air ; and in this way it may, at leall, be llrongly fufpecled to re- ceive an addition of another principle. Why thenfhould thefe bercgHrucd as its conllitucnt principles? And as inthetwolimpleftmethods of decompofition, inwhich the re-aclion of no forciij;n fubftancc can be (uipeclcd, it appears in the form of dephlogiilicated, phlogiflica- ted, and fixed air ( the former always containing a por- tion of the two lail), why then fliould not thefe be ac- counted its true conflitucnt parts ? This theory '■'i • is further confirmed by reflcdiug on the manner in naturally which nitrous acid is generated by nature. Mr generated. Thouvencl found that this acid is conllantly produced when ehalk is expofed to a mixture of putrid air and common air, or putrid and dcphlopiiticated air ; but if die putrid air be paflTed through lime-water, it is ne- ver generated ; and that it is rarely produced by the cx- pofurc of quick lime or fixed alkalis to thtfc airs. The reafon tha; alkalis, though aerated, are not fo proper, is, that they do not comliine with phlogiflicated air as calcareous ear;hs do. Mr Cavendilh, indeed, pro- duced nitrous acid without any apparent mixture of fixed air ; but the atom of it uecciFary for the for- mation of the fniall q-ianiity of nitrous acid he proJu- 3 10 Fixed air one of the elements of nitrous acid. II How ni- ced (about one-third of a grain), might well be con- Aci.li. tained in iht; phlogiflicated air he employed, or perhaps ' formed in the operation." Having thus far ftatcd the different opinions of the mofl celebrated French and Englilh philofophcrs concerning the compofition of acids, it is iicccirary n to take notice of fome experiments made by Mr Experi- M'att, in order to determine whether the dcphlo- ments by gillicatcd air produced from nitre really proceeds from ^^. ^'*", a decompofition of the acid, or what ouantity of the T" , • ' -J „: J ' . ' feem cou- latter is required to conftitute a determinate quan- ,^^j. j^j^j^ tity of the former. To afcertain this *, 240 grains of Kirwan't mercury were put into a glafs retort with 480 grains dodrine. of diluted dephlogiilicated nitrous acid, which was the ' I'hiloi. quantity necclfary todilfolve the whole of the mercury; Tranf. and as loon as the common air was expelled, a proper ^'' "'*' vcflel was applied to receive the air produced in the''' operation. Sixteen ounce-meafures of nitrous air came o\er during the folulion, and on changing the recei- ver, a quantity of dilute, but higlily phlogiflicated ni- trous acid, was obtained. The air receiver being again applied, fou rounce-meafures of llrong and pure nitrous air wereobtjined, which, by the dephlogifticated air that arofe immediately after, were reduced to half an ounce-meafure. The production of dephlogiflieatcd air continued very rapid, the mercury being all the while received, until the operation was ended by the dillillation or fublimaiion ofthe whole of the mercury. Two hundred and eighteen grains of the metal were obtained in its running form, and 32 remained in the form of an orange-coloured fublimate in the upper part of the retort. — -The 16 ounce-meaiurcs of nitrous air, firll obtained, were then converted into nitrous acid by the gradual admiffion of common air, and then added to the water in the bafon in which the receiver had been inverted ; the whole quantity being about two quarts, and very acid to the tafle, fparkling at the fame time with nitrous air. To determine the quantity of acid thus recovered, as well as that which remained in the fublimate , a folution of alkali of tartar was made ; and by experiment it was found, that 120 grains of the acid, originally employedin diflblving the mercury, fa- turated 5 j2grainsof this folution ; theorange colour- ed fublimate and all the acid liquorrecovered being fa- turated by 1595 grains ofthe fame. Hence it appears, by the rule of proportion, that out of 480 grains of nitrous acid originally employed, only five were lofl ; " a fuialler quantity (asMr Wattjuflly obferves) than what might reafonably be fuppofed to be lofl in the procefs by the extreme volatility ofthe nitrous acid." His couclulion therefore is, that " the nitrous acid docs not enter into the compofition of dephlogiilicat- ed air : it feems only to ferve to abforb phlogillon from the watery part ofthe mercurial nitre." This experiment was repeated with cubic nitre, and only 30 ounce-meafures ofair diliilled from an ounce ofthe mineralalkali exadly faturated with nitrous acid. The water through which the air paii'ed was acid, and the reliduum in tlie retort all^aline ; but on mixing the two together, the folution was found to be exatlly neu- tral by every pollible teft. Notfatisticd with thefe experiments, ?'Ir Watt di- ftillcd an ounce (4S0 grains) of common nitre, flop- ping the procefi when 50 ounee-meafurcs of air had been produced. This air had a flrong fn-.cU of the nitrous A C I 73 1 /v c I Aciils. nitrous acid, frcm wliicli it couUl not be iVced by \va(l;- ^""■^' ing witli tlie water in tlie bai'on. Tlie rciidiuiin in tlic retort was alkaline as before, and the water (lightly acid ; iior was the faluration cojnpletcd by mixing the two together. Ten grains of weak nitrous acid, 105 grains of which contained the acid of6o of nitre, com- pleted the fatiiration. Tliefc ten grains contained the acid of 5 7 grains of nitre; which, by Mr Kirwan's ex- periments, is equal to two grains of real nitrous acid. " \S't have therefore (fays fir Watt) 3<;gr?ins weight of dephlogillicated air produced, and only two grains of real acid milling j and it is not certain that even this quantitywasdeftroyed bccaufc fomc portion of thcglafs of the retort was diiiolved by the nitre, and fonie part of the materials employed in making the glafs being alkali, we may conclude, that the alkali of ihe nitre would be augmented by the alkali of that part of the glafs it had diflblved ; but as the glafs cracked into fmall pieces on cooling, and fome part of tlie coating adhered firmly to it, (he quantity of the glafs that j^ was diilolvcd could not be afcenair.ed." ^nrwcrca To avoid the force of objedions drawn from thefc jy MrKir- experiments, and which fecm ready to overthrow his ivau. hypothefis, as well as that of Mr Lavoilicr entirely, Mr Kirwan mskcs the following reply " Wy inge- nious friend Mr M'att, as well as Mr Cavcndilh, are of opinion, that the whole quantity of dephlogifticated air, produced from ihediftillation of nitre, arilesfrom the dephlogiflicatini of the water it contains, it being decompofed by the nitrous acid, which then becomes phlogillicated. Thisopinion is expofcdto infurmounc- able dilliculties. For, in the firft place, nitre affords de- phlogillicatcd air at the rate of 146.125 cubic iriches for every hundred grains of nitre, which, by the proper allowances for phlogiilicattd air, fliouKl weigh 46.77 grains: but then dephlogiliicatcdairisonly oncof the conftituent parts of water, for it contains i^/'^r cf/it. of inflammable air, that is to fay, 87 grains of dcphlo- gifticatcd air : to form 100 grains of v. ater requires an addition of i 5 grains of inrtammable air ; confcquent- ly 46.77 grains of dephlogiftlcatcd air require nearly 7of inflammable air, and would then form 5?.77grains of water, which exceeds half thcwtight of the nitre ; a quantity of water, as Mr Watt owns, certainly in- adniiiliblc. Mr V.'att found, that the water over which the .-"ir proceediirg from the decompofition of o grains of nitre had been reieived, contained only the acid belonging to 120 grains of nitre ; and even this fmall qnandiy he inferred onlyfron\ my cxpcrimctits. IJut r.iy experiments arc totally inapplicable in this cafe; for I iifed only the dci>hlogi!iicjttd nitrous ,1- cid : and alkalis arc faiurable by a much fmallcr quan- tity of phlogifticated than of dephlogifticated acids, as is evident in ihc cafe of lhctifp}ci^i/lici>t,;Jmari/ii a.tid, as Stahl long ago obferved ; for he fays, that the vo- latile acid of fulphur faturates 10 times :is nnicli :ilkali as the fixed. Mr Btrjirian and Mr Scheeleobfcrvcd, that nitlicd nitre is llill neutral, though it be phlo- gifticatcd ; iheitforc it is air, and not water, which it wants. Accordingly Dr Priclllcy found it to injure coTTiTTion air by attri ling its dephlogiftici-.ted part : but if it be keja in fufion for fome time, it lofcs its a- cid, and becomes alkaline j and the air it receives mud furcly be deemed rather to recompofc the acid than to form water ; of whofc formation, in the Vol. I. temperature of the atraofphcrc, wc have no fort of proof. On the contrary, the impoiSbility of ac- ceuniing for the lofs of acid in this cafe is an evident proof of the fallacy of that hypothefis By MrLavoi- ficr's analyfis, 100 grains of nitre contain 5J of caj- Aic alkali ; by Mr Bergman's, 49; by Mr {('ISIizers, 52 ; by Mr Wicgleb's, 461 ; by mine, 63 : the mean of all wliicli is, 5;', ; which leaves 46. j for acid anT^of iron, or in a gun-birrel, it fcarrc gives out anv other than fixed air ; if at any time it gives out dcphl.i.^ifticatcd air, with little or no mixture of lixed air, this isow ing to a very perf'cd de.dilo^ifticatioii of liic calx, and to its containing very little moifturc.

A C I C 74 1 A C I Acids, having pafled the fleam of boiling water through man- — ^ ■ ganclelieatedin an earthen tube, obtained a very large quantity of fixed air, and fcarce any other ; though on repeating this experiment with manganefc well freed from calcareous earth, I obtained a large portion of dc- phlogilUcated air ; but I believe mueh depends ontlic degree of heat to which the tube is fubjeflcd. But having (J illillcd manganefc, which yielded of iifclffome fixed air with common fpirit of fait, I obtained de- phlogilticated marine acid, and not a particle of fixed air; which fliows that this lall combined with the de- phlogiflicatcd bafis, and formed the dcphlogilficated acid. Mr Hermlladt having dilfolved the black calx in common marine acid, and precipitated it with an ae- rated llxed alkali, obtained, as ufual, a white preci- pitate ; which, when heated, afforded a great part of the fixed air it had abfurbcd from the alkali ; but when heated to fuch a degree as to be of a brown red colour, and confequcntly dcphlogifticatcd, it converted com- mon fpirit of fait into a dcphlogillicaied acid, wliich With regard to the acid of fugar, Mr Kirwaii ob- ferv cs, that fugar itfelf is a compound of fixed air witii a much larger proportion of inflammable air, and fome Water, all coudenfed to a degree of which wc are ig- norant, but retaining, upon the whidc, much more fpecilic heat thancither oil or charcoal ; tho' he feems iucliiicd to the hypotheiis of Mr Morveau, that this fubilance has for its bafis a fine ethereal oil, to which a large proportion of condeufed iulianimable air is fu- pcradded. The acid of fugar, then, according to him, confilts of this peculiar bafis deprived of its fuperfiuous phlogitlon,and united to a great quantity of fixed air in a concrete ftale. JJe is alfo of opinion, that it docs not cxifl ready formed in tlie fugar, but is produced in the operations that fubilance undergoes : that it de- rives mofl of its acid principle from the nitrous acid employed ; the nitrous balis taking up the phlogiflon, and the fixed air of the nitrous acid combining with the faccharine bafis. He contefts flrongly an opinion of Mr Lavoificr, that fugar is a fort of charcoal, which.

On this fert; but the following, he is of opinion, fully confirms his hypothcfis, and fubverts that of the antiphlogifUans. '' Six cubic inches of inflammable air were mixed with as much dephlogilUcated marine air over lime-water. In about 10 minutes af'tcr the greater part of the di- minution had taken place, a white cloud appeared on Mr Kirwan remarks, i . " That, according to this the- ory, the acid of fugar lliould be the fame with fixed air, flnce both are compofcd of the oxygenous prin- ciple united with charcoal; or, if Mr Lavoifier fliould reply, that fugar is different f'rom common char- coal, he reminds him, that, according to his own ta- the furface {a) of the lime-water, and by agitation it ble of affinities, the oxygenous principle has a much became Ifill more turbid. As it was poliible that the Ifronger attraction for charcoal than for fugar, and manganefe might be mixed with calcareous earth, fome confcquently that the latter ought to be decompofcd dcphlogilficated marine air was extrafled from another by the former ; nay, that it fliould be regenerated by portion^of it, and received on lime-water ; but it was various metallic fubftances, which, according to him. 19 Phofphoric acid. have a greater attraction for this principle. 2. Accor- ding to this hypothefis, the fiicchariue acid ought to weigh n'ore than the fugar employed in the operation ; w hich is fo far from being the cafe, tliat it is univcr- faliy agreed to be much Icfs ; Bergman making it only wholly abforbed, w ithout forming the leafl cloud, tho there was lime enough ; for, on adding aerated water, a cloud appeared." The other acids particularly treated of by Mr Kir- wan are the phofphoric and facchiirine. In his ireatile on the former, he adopts the analyfls of Mr Lavoifier, changing only his acid principle of dephlogifficatcd for fixed air. From this it appears, that the phofpho- ric acid confiffs of a peculiar balis united to 2.265 of its weight of the acid principle ; or, in other words, treating fugar v.'ith the black calx of manganefe, or 100 grains of dry phofphoric acid contains about 69 of with dcphlogifticatcd marine acid ; both of which, ac- id, Mr Chaptal from ;d to iths, and Mr Sage inhs. 3. If the faccharine acid confifbed of fugar, or confifl- ed of that fubilance undecompofed, and barely united to the oxygenous principle, it ought to be formed by fixed air and 31 of its peculiar balis : 100 grains of the phofphoric balls take up 226.5 of fixed air, or 32.9of phlogiflon when it becomes phofphorous; and 100 grains of phofpliorus contain 75.24 of balis and 24.76 of phlogiflon. — The bafis of this acid is the only one that can be procured free, both from the phlogi- flon and the acidifying principle ; it is called, though improperly, as it is not foluble in water, \^\^ glacial phofphoric acid. Mr Lavoifier and others are of opini- on, that phofphorus is a flmple fubilance containing no phlogiflon, and that the acid confifls of the oxyge- nous principle united to it. cording to him, have lefs attraction for the oxygenous principle than fugar. Laflly, (fays Mr Kirwan), if the acid of fugar be diftilled, it is wholly converted into water, fixed inflammable air, and not a particle of coal or dephlogifticated air is found in it. It is not there- fore reafonabletolook on either of them asitsconflitu- ent principles ; but as fixed air alone can be extrac- ted f^rom ail vegetable acids, it feems to be the true a- cidifiablc principle. Having given a \iew of the prefenc opinions re- lative to the original formation of acids, it remains to treat a little more particularly of each of the different kinds. 21 Fixed air the acid principle, according to fVIrJCir- wan.

Acids, liow divulcd. 23 Enumcra- i4 Gsneral ac- count of their at- tra:c, are the flrong- eft of them all ; that is, if any other acid be united to an alkali, earth, or metal, the union will be broken by adding to that compound any of the three acids jull mentioned. Neither arc thefe equal in power among themfelvcs ; fop the vitriolic is (Ironger than the ni- trous, and the nitrous ftronger than the marine. The rule, however, is liable to certain exceptions and vari- ations, depending chiefly on the circumftances of heat or cold, moilfure or drynefs, and particularly on the Aatc of the marine acid \\ith regard to its being in the form of an aqueous fluid or reduced to a dry vapour. In this laft cafe it fcems flronger than cither the vi- triolic or nitrous ; and even when in an aqueous flate, both the nitrous ana marine acids, when added in great quantity, feem to opprcfs and overwhelm the ftronger vitriolic acid, fo that they w ill partly expel it from an alkaline filt. This docs not depend on tlie mere quan; tity of acidity they polTefs : for the acetous acid may be concentrated to fach a degree as to become flronger in this refpec^ than fpirit of fait ; yet it will always be in- ferior in pointofre.il ftrength, when tried with anal- kali in competition with the latter. The aerial acid is the wcakeft of all ; and may be expelled not only by vinegar, but by the acid jui es of fruits, tartar, and the acids of tungften and molybda:na. Some acids have the property of refilling the lire, and melting into a kind of glafs, fuch as that of borax and phofphorus. This circumllance gives them an ad- vantageover the ftrongeracids whichare volatile; and thus the two juft mentioned, as well as thofc of arfcnic and tungften, will, in a very flrong heat, expel the a- cid of vitriol itfclf, though the latter will, in the cold, expel any one of them with great cafe. Both the vitriolic and nitrous acids have a very ftrong attraction for phlogiilon ; and unite with certain oily and inriammablc matter fo vehemently as to occafion great heat, and fometiincs even violent and uacxtin- guilhablc flame. This is particularly the cafe with the nitrous acid, or with a mixture of the two ; and indeed the nitrous acid, though weaker than the vi- triolic, (hows itfclf in every inllancc to be far more ac- tive, and to perform all its operations with vallly great- er rapidity, than the other.

The lycodonum, or yellow wolfsbane, grows upwards of three feet high, flowers about the middle of June, and if the feafon is not warm will con- tinue in flower till Augufl. 2. The altilfimum, or greatell yellow wolfsbane, grows upv/ards of four feet high, and the fpikesof its llower are much longer in this fort than the former. 5. The variegatum, or Icller wolfsbane, feldom grows more than two feet high, it carries blue flowers, and the fpikes of them arc much Ihorter than either of the two laft. 4. The anihora, or wholefoinc wolfsbane, liowers in the middle of Auj^uJl, and often continues in beauty tillthe middle of September ; its flowers are not large, but are of a beautit'ilfulphur-yellow colour, j. The napcllus, bears large blue flowers, which appear in Augult, and make a pretty appearance. There are two or three varieties of this kind ; one with white, another with rofe-co- loured, and a third with variegated fiowers : but thefc arc oiily varieties which often change. 6. The Py ra- midalc, or common blue monkdiood, bears a long fpike of blue flowers, which appear foontr than any of the other forts, being fo early as June, or fonietinies even May. The fpikes of liowers are upwards of two feet long, fothat it makes a pretty appearance ; the feeds are ripe in September. 7. The alpinum, or large- flowered nionklhood, flowers in Augnft, and will grow to the hci;;ht of live feet in good ground ; the flowers are very large, of a deep blue colour, but not many upon eacjt fpike. S. The pyreniacum, or Pyrcnean monkfliood, flowers in July. It grows about four feet high, and carries a long fpike of yellow flowers. 9.

Culture. All thefe fpecies, except the lafl, arc na- tives of the Alps, the mountains of Germany, Au- flria, and Tartary ; fo require a cool Ihady (ituation, except the wholefome wolfsbane, which mufl: have an open expofure. They tlirive better in a moid than dry foil : but the ground mull not be fo wet as to have the water flanding near their roots in the winter-time. Aconitum, They may all be propagated by fowing their feeds in ' " ' autumn, upon a north boi der, \\ here they are fcrcencd from the fun. The plants will come up in the fpring, when they mufl be kept clean from weeds during the fummer-months : and in very dry feafons, if they arc frequently refreflied with water, their growth will be greatly promoted. 'J he following autumn they fnould be tranfplantcd into Ihady borders, in rows afoot afunder, and the -plants fix inches diflant from one another. In this fituation tlity may remain two years, when they will carry flowers, and fo may be tram'- » planted to thofe places where they are to remain. The caftcrn monklhood is a native of the Levant, from whence the feeds of it were firfl fcnt by Dr Tourne- fort to the royal garden at Paris, from whence fonie other gardens have been furnifiied with feeds. It is very rare in Europe at prefcnt. Q^iahiies. Since tlie time of Theophraflus, mofb of the fpecies of monk ll'.ood have been reckoned a deadly poifon both to men and brutes. Diofcorides, however, recommends the cxtcrnahpphcation of common monks- hood for pains of the eyes. The flowers of a great many fpecies comminiicate their noxious quality by being fmcllcd to ; and thofe of the fpecies called /;«- pelltts being placed on the head, occafion a violent me- grim. Of the bad qualities of thefe plants wc fonie- times avail ourfelves to get rid of vermin. A decoc- tion of the roots deflroys bugs ; the fame part being powdered, and adminillered in bread or fome other pa- latable vehicle to rats and mice, corrodes and inflames their inteftines, and foon proves mortal. The juice of the plant is ufed to poifon fltfli with, for the deflruc- tion of wolves, fo.xcs, and other ravenous beaffs. The bell antidote to the poifon of the different monks- hoods is faid to be the root of the anthora, a fpecies of the fame genus, hence termed keaitl-f'ul or vjl-o.'efotHi nionkjh'jod . The fame plant is regarded as efTicacious againfl bites of ferpents and other venomous creatures. The roots have a bitter acrid tafle ; the leaves are only bitter : the former arc chiefly ufed in medicine ; and, bclides the excellent quality jufl mentioned, are flo- machic, Vi\iS. promote perfpiraiion. The pcafants, who gailier the plants on the Alpsand Pyrenees, are faid to ufe it with fucccfs againA the biting oi mad dogs, and to cure the cholic. It is remarkable, that the monks- hoods with blue flowers are much more virulent than the yellow or white-flowered kinds. Miller alTcrts that the hunifmen of the wolves and other wild beads on the Alps, dip their arrows into the juice of thofe plants, which renders the wounds made by ihem deadly.

The /i./////?/w has a gibbous oblong germcn the length ef the ftamina ; no (tylus -, the ftigma a promi- nent point. The pcrscarpiinii is a fliort triangular, obtufe, three-celled capfule, attenuated at both ends. Thtfccdi are numerous, and of -an oblong egg-lTiape. There is but one<{ elcdric m'attcr by ilfclf, can never excite a degree of a- gitation in it fulFicient for producing a found ; but if the elciJlric fluid is entangled among the particles of air, water, wood, metal, &c. whatever affeds their panicles will alfo afiVa this fluid, and produce an audible noifc. In the experiment of the air-pump, however,thcrc may be an ambiguity, as the gradual cxhaulling of the air creates an incrcafing difference of preffure on the outfidc, and mayoccalion in the glafs a difficulty of vibrating, fo as to to render it lefs lit to communicate to the air without the vibrations that flrike it from ■within. From this caufe the diminution of found in an cxhanlted receiver may be fuppofcd to proceed, as well as from the diminution of the air. But if any internal a.^iration of its parts ihould happen to the elec- trical fluid, exceeding loud noifcs might be propagat.-d thrpugh it, as has been the cafe when lirgc mcirors have kindled at a great diflance from the earth. Iiis alfo difficult to account for the exceeding great hviftncfs- of found, upon the fuppofition that it is propagated by means of air alone ; for nothinn; is more certain, than that the flroiigell and moil violent gale is, in its courfe, inert and ihiggilh, compared with tlie jisoiiou of found . So A C O U S Sound. I'latc I Different in the motion of tlic air when Aruck upon by a founding riicoriesof body. To be a little more prccifc, fuppolcAHC, the Itriiigof an harplicliord fcrcwed to a proper pitch, and draw a out of the right line by ihc finger at B. \S'e Ihall have occaliou clfcwhere to obfervc, that fuch a ilring would, if let go, vibrate to E ; and from K to D, and back a.;ain ; tliat it would continue thus to vibrate likcapcndulum forever, if not externally rcfiflcd, and like a pendulum, all its little vibrations would be pcr- lornicd in equal times, the lad and the firfl being c- cjually long in performing ; alfo, that, like a pendulum, its grcatcll fwiftnefs would always be when it arrived at K, tlic middle part of its motion. Now then, if this ftring be fuppofcd to tly from the ringer at B, it is ob- vious, that whatever be its own motion, fuch alio will be the motion of the jiartsof air that fly before it. Its motion, as is obvious, is firft uniformly accelerated for- ward from B to K, then retarded as it goes from K to D, accelerated back again as it returns from 1) to E, and retarded from Elo B. This motion being tliere- fore fent in fucccffion through a range of elaflic .lir, it mufl happen, that the parts of one range of n'lv nnifl bcfent forward with accelerated motion, and then witli a retarded motion. This accelerated motion reaching thcrcmotert; end of the firfl range will be coninuini- cated to a fecond range, while the neare ft pans of the iirft range being retarded in their motion, and falling back with the receinon of the ftring, retire firft with an accelerated, then with a retarded motion, and the rcmoteft parts will foon follow. In the mean time, while the parts of the lirft range are thus falling back, the parts of the fecond range are going forward with an accelerated motion. Thus there w ill be an alter- nate condenfation and relaxation of the ;iir, during the tiine of one vibration; and as the air going forward ftrikcs any opnoling body with greater force than upon retiring, foeach of thefe accelerated progreinons have been called by Newton a pn/fc of found. Thus will the airbe driven forward in the direction of the ftring. But now we nuift obfcrvc, that thefe pulfes will move every way ; for all motion imprelFed upon fluids in any diredion whatfoevcr, operates all around in a fphere : fo that founds will be driven iii all directions, backwards, forwards, upwards, downwards, and on every fide. They will go on fuccccding each other, one on the outfidc of the other, like circles in diftnrbcd water ; or rather, they v.-ill lie one without the other, i.i concentric Hulls, Ihell above flicll, as wc fee in the coats of an onion. All who have remarked the tone of a bell, while its founds arc decaying away, mull have an idea of the pulfesof found, which, according to Newton, are form- ed by the air's alternate progrellionand recelllon. And it muft be obfcrvcd, that as each of thefe pulfes is formed by a lingle vibration of the ftring, they muft be equal to each other ; for the vibrations of the ftring are known to be lb. Again, as lothe vdo-rity with which founds travel, this Newton determines, by the moft diliicult calcula- tion that cm I)c imagined, to lie in proportion to the thicknefs of the parts of the air, and the diilancc of thefe pirts from each other. From hence he goes on to prove, that e a-h little part moves backward and for- ward like a pendulum ; aiid from thence he proceeds to demon Itratc, that if the atmofpherc wereof tlic fame TICS. Chap. I. denfity every where as at the furface of the earth, in Different fuch a cafe, a pendulum, that reached from its highcft Theories of fui-face down to the furface of the earth, would by i:s ^"" "^' vibrations dilcovcr to ns the proportion of its velocity with which founds travel. The velocity with which each pulfc would move, lie fliows, would be as much greater than the velocity of fuch a pendulum fwinging with one complete vibration, as thecircnmfcreneeofa circle is greater than the diameter. Fnm hence he calculates, that the motion of found will be 979 feet in one fecond. But this not being confonant to ex- perience, he takes in another conlidcration, which de- ftroys entirely the vigour of his former dcmonftration, namely, vapours in the air ; and then finds the motion of found to be 1142 feet in one fecond, or near i 5 miles in a minute : a proportion which experience had cJta- bliHied nearly before. 7 Thus much will ferve to give an obfcnre idea of a Trrccdirg theory which has met with numbers of oppofers. Even 'I'licory op- John Bernouilli, New ton's grcatefl difciple, modeftly V^'^'^- owns that he did not pretend to underftand this part of the Priuci/'ia. lie attempted therefore to give a morepcrfi)icuous dcmonftration of his own, that might conrirm and ilhiftrate the Newtonian theory. The fubjeft feented to rcje(5l elucidation : his theory is ob- vioully w rong, as D'Alerabcrt has proved in his The- ory of Fluids. g Various have been the objeiflions that have been The objcc- madc lothe Newtonian fyfttm of founds. It is urged, tions. that this theory can only agree with the motion of found in an elaftic fluid, whereas founds are known to move forward through water that is not elaftic. To explain their progrcfs therefore through water, a fe- cond theory nuiil be formed : fo that two theories muft be made to explain a limilar cfTefl ; which is contrary to the fimplicity of true philofophy, for it is contrary to the fimplicity of nature. It is farther urged, that this flow vermicular motion but ill reprefcntsthe velo- city with which founds travel, as we know by experi- ence that it isalmoft i^ miles in a minute. In fhort, it is urged, that fuch undulations as have been defcri- bcd, when coming from feveralfonorous bodies at once, would crofs, obftruft, and confound each other ; fo that, if they were conveyed to the ear by this means, we fhould hear nothing but a medley of difcord and broken articulations. But this is equally with the reft contradictory to experience, lince we hear the fnlleft concert, not only without confniion,butw ith the high- cft pleafure. Thefe objcftions, whether well founded or not, have given rife to another theory : which we ftiall likcwife lay before the reader ; though it too ap- pears liable to objedions, which fliall be afterwards mentioned. „ Every found may be confidcred as driven of! from Anotlicr the founding body in ftraigjit lines, andimprcfTcd upon 'I'hcory. the air in one direction only : but whatever inipreilion is made upon a fluid in one direftion, is diffufed upon its furface into all directions ; fo that the found firft driven direitly forward foon fills upa w ide fphere, and is heard on every fide. Thus, as it is imprcffed, it in- ftantancouHy travels forward with a very fv.ifi motion, refembling the velocity with which wc know eledri- city flies from one en i of a line to another. Now, as to the pulfes, or clifc Ihakcs, as the niufi- cians cxprcfi it, which a founding body is know-n to make ACOUSTIC Chap. I. DifTercnt make, each pulfc (fay the fupportcrs of tliis ihcoiy,) Tlicoricsof IS itftlf a diltiiiLt aiul pcrftit found and die interval Sound, between every two pulics is profoundly lilcnt. Con- ^tinuity of found froju the fame body is only a decep- tion of tlic hearing ; foras each dillinit found fuccccds at very fmall intervals, the organ has no time to tranf- mit its images witii cijual fwiftnefsio the mind, and the interval is thus lod to fcnfe ; jiill as in feeing a flaming torch, if liarcd round in a circle, it appears as a ring of fire. In this manner a beaten drum, at fome fmall dillance, prcfenis us with the idea of con- tinuing found. When children run with their-llicks along a rail, a continuing found is thus rcprcfented, though it need fcarce be obferved that the ftroke a- gainil each rail ispcrfedtly dillinctand infulated. According to this theory, therefore, the pulfcs are nothing more than dillinct founds repeated by the fame body, the firll llroke or vibration being ever theloud- cft, and travelling farther than (hole that follow; while eachfucceeding vibration gives a new found, but with diniinilhcd force, till atlall the pulfcs decay away to- tally, as the force decays that gives them exillenee. All bodies whatfoevcr that arc flruck return more orlefs a found : but fome, w-antingelafticity, give back no repetition of ihe found ; the noife is at once begot- ten and dies : while other bodies, however, there are, which being more claAic and capable of vibration, give back a found, and repeat the fame feveral times fuc- ccflively. Thcfe lall are faid to have a tone ; the others are not allowed to have any. This tone of the elaflic llring, or bell, is notwith- flanding nothing more than a fimilar found to what the former bodies produced, but with the diifercnce of being many times repeated while tluir note is but fmglc. So that, if we would give the former bodies a tone, it will be neccllary to make ihcm repeat their found, by repeating our blows fwiftly upon them. This will ctfcttually give them a tone ; and even an nnmuli- cal inllramcnt has often had a fine cii'cci by its tone in our concerts. Let us now goon then tofuppofe, that by fwift and equably continued Itrokes wc give any non-ela(\ic body its tone : it is very obvious, that no alterations will be made in this tone by the quicknefs of the llrokes, though repeated ever fo faA. Thefc will only render the tone more equal and continuous, but make no al- teration in the tone it gives. On the contrary, if we make an alteration in the force of each blow, a dirte- rent tone will (hen undoubtedly be excited. The dif- ference will be fmall, it mult be confelfed ; for the tones of thefc inflcxilile bodies are capable but of fmiU variation ; however, there will certainly be a diffe- rence. The tabic on which wc write, for inllance, will retnrn a dirl'crcnt found wlitn ilruck with a club, from whatit did when (truck only with a fw itch. Thus non-dailic bodies return a ditrcrcncc of tone, not in proportion to the fwiftncfs with which their found is repeated, but in proportion to the greatncfs of the blow which produced it ; for in two equal noii-tlallic bodies, the body produced the deepell tone which was Ilruck by the greatcft blow. Wc now then come to a critical qncftion. What is it that produces the diticrenec of tone in two elallic founding bells or llrings.' Or what makes one deep and the other (hrilHThisnucftion has alwaysbcen hitherto Vol.. I. ai'.fwcred by faying, that tlic depth or luigtit of the niffcrcut note proceeded from the flowncfs or fwiftncfs of the 'I'ix-critt vt tiuics of the vibrations. The llowcA vibrations, it has Sound, been faid, arcqualifiedforproducingihc deepefltoncs, " "* while the fwifteil vibrations produce the Iiighcft tones. In tliis cafe, an cffccl has been given for a caufc. It i» in fait the force with which tlie founding ftringftrikci the air when Ilruck upon, that makes the tr.- .- diflinc- tioninthe tones of founds. It is this force, withgrcat- erorlcfsinipreliions.refemblingthegreater orlefs force of the blows npon a nou-elaftic body, which produce* correfpondent affcflions of found. The greateft forces produce the deepcll founds : the high notes are the cf- fc6l of fmall efforts. In the fame manner a bell, wide at the mouth, gives a grave found ; but if it be very maliy withal, that will render it Hill graver ; but if mally, wide, and long or high, that will make the tone decpcft of all. Thus, then, will claftic bodies give the deepcll found, in proportion to the force with which they ftrike the air : but if we fliould attempt to incrcafc their force by giving them a llronger blow, this will be in vain ; they will flill return the fame tone ; for fuch ii their formation, that they are fonorous only becaufe they are elaftic, and the force of this clalHciiy is not increafed by our ftrcngth as the greatncfs of a pendu- lum's vibration will not be increafed by falling from a greater height. Thusfar of the length of chords. Now as to the fre- quency with which they vibrate the'deepefl tones, it has been found, from the nature of elaflic llrings, that the longed Arings have the widcA vibrations, and con- fequently go backward and forward llowcA; while, on the contrary, the lliortcll Arings vibrate thequickcA, or come and go in the LiorteA intervals. Krom hence thofc whohave treatcdof founds, have alicrted, as was faid before, that the tone of the Aring depended npon the length or the Ihortnefs of the viljratioas. Tliis, however, is not the cafe. One and the fame Aring, when Aruck, muA always, like the fame pendulum, re- turn precifcly fimilar vibrations ; but it is well known, that one and the fame Aring, when Aruck upon, does not always return precifcly the fame tone : fo that in this cafe the vibrations follow one rule, and the tone another. The vibrations muA be invariably the fame in the fame Aring, which does not return the fame tone invariably, as is wcUknown tomuliciansinE:cner.al. In the violin, lor in Aancc, they can calily alter the tone of the Aring an oclavc or eight notes liigher, by afoftcr method of drawing the bow ; and fome are known thus to bring out the moA charming airs imaginable. Thefc peculiar tones arc by the Englillt fiddlers cMedfut:- liott'i. Tlic only rcafon, it has been alleged, that can bealligned for the fame llring thus returning different tones, mull certainly be the ditferent force of its Arokes upon the air. In one cafe, it has double the tone of the other ; becaufe upon the foft touches of the bow, only half iss elaAicity is put into vibration. This being under Aood (continue the authors of this theory), we ihall be able clearly to account for many things relating to founds that have hitherto been inexplicable. Thus, for inftance, if it be alk- cd.

The anfwcris, The longell llringwill receive all ihc force of the firing half as long as iifilf, and there- fore it will vibrate in proportion, that is, ilirongh half its length. In the fame manner, if the longell firing were three times as long as the other, it would only vibrate in a third of its length ; or if four times, in a fourth of its length. In Ihort, whatever force the finallcr firing imprellcs upon the air, the air will im- prefs a limilar force upon the longer llring, and par- tially excite it2 vi'urations. From hence alfo we may account for the caufe of thofe charming, melancholy gradations oi found in the Eolian lyre ; aiiiulhumcnt (lays Sir John Hawkins) lately obtrudeil upon the public as a new inveuiion, though defcribed above a century ago by Kirchcr *. This inftrunient is ealily made, being nothing more than a long narrow box of thin dale, about :!o inches long, J inches broad, and i J inches deep, with a cir- cle in the middle of the upper fide or belly about \\ inch diameter, pierced wilhfmall holes. On thiilide are fcven, ten, or (according to Kirchcr) fifteen or more llringsof very tine gut, llretched over bridges at each end, like the bridge ot a riddle, and fcrewedup or re- laxed with fcrew-pins (b). The firings are all tuned to one and the fame note ; and the inllrunient is placed in fomc current of air, where the windcau brufh over its firings with freedom. A window with the fafh j ufl railed to give the air admiirion. will anfwer this purpofc exa-Hly. Now when the entering air blows nponthefe firings with ditFerent degrees of force, there •will be excited different tones of found ; fometimes the blafl brings out all the tones in full concert ; fometimes it links them te the fofteft murmurs ; it feeis for every tone, and by its gradations of flrength folicits thofe gradations of found which art has taken different me- thods to produce. It remains, in the lafl place, to conlider (by this theory) the loudncfs andlowncfs, or, as thcmulicians fpeak, the flrength and foftncfs of found. In vibra- tino- claflic firings, the loudnefs of the tone is in pro- portion to the deepnefs of the note ; that is, in two firings, all things in other circumfiances alike, the dcepeft tone will be loudefi. In mufical infiruments upon a different principle, as in the violin, it is other- wife ; the tones are made in fuch infiruments, by a number of fmall vibrations crowded into one firokc. The rolined bow, for infiance, being drawn along a firing, its ronghnelVes catch the firing at very fmall intervals, and excite its vibrations. In this iiifirument, therefore, tocxcite loudtones, the bowmufi be drawn quick, and this will produce the greatefi number of vi- brations. But it muft be obfcrved, that the more quick the bow pafles over the firing, the lefs apt will Chap.

By the fame theory (it is alleged) may all the phe- _,. " nomciia of mufical founds be eafily explained. — The j^j- i^iif,.-ii fables of the ancients pretend, that mulic was firll Sounds il- found out by the be;.tiiig of different hammers upon the luflrated fmiih's anvil. W ithout purluing the fable, let us en- according deavour to explain the nature of mufical founds by a to'l^ef*'"* limilar method. Let us fuppofc an anvil, or Icveral li- '""'y- niiiar anvils, to be llruck upon by fcveral hammers of ditferent weights or forces. Tlie hammer, which is double that of'anoilier, upon fiviking the anvil will produce a found double that of the other : this double foui.d muficians have agreed to call an Oclave. The ear can judgeof the difterenceor refeniblance of thcfc founds with great eafe, the numbers being as one and two, and therefore, very readily compared. Suppofc that an hammer, three limes lefs than the rirfi, flrikes the anvil, the found produced by this will be three times leis than the firit : fo that the ear, in judging tho liniilitude of thefe founds, uill find fiimewhat more difliculty ; becaufe it is not fb eafy to tell how often one is contained in three, as. it is to tell how often it is contained in two. Again, fuppofe that an hammer four times lefs than the hrft firikes the anvil, the ear will find greater (lifhculty fiill in judging prccifcly the difference of the founds; for the ditfcrence of the num- bers four and one cannot fo foon be determined with precilion as three and one. Ifthe hammer be five timcslefs. the dilFiculty of judging will be fiill greater. If the hammer be iix times lefs, the difficulty fiill in- creafcs, and fo alfo of the fcvcnth, infomuch that tlic car cannot always readily and at once determine the precife gradation. Now, of all comparifons, thofe which the mind makes mofi ealily, and with leaft la- bour, are the mofi pleafing. There is a certain re- gularity in the human foul, by which it finds happi- ncfs in exad and ftriking, and eafily-madc compari- fons As the ear is but an infirument of the mind, it is therefore mofi pleifcd with the combination of any two founds, the ditFerences of which it can mofi rea- dily difiinguilh. It is more pleafcd with the concord of two founds which are to each other as one and two, than of two founds which are as one and three, or one and four, or one and five, or one and fix or fcven. Up- on this pleafure, which the mind takes in comparifon, all harmony depends. The variety of founds is infi- nite ; but becaufe the ear cannot compare two founds fo as readily to difiinguilh their difcrimalions when they exceed the proportion ofoneand feven,mulicians have been content to confine all harmony within that compafs, and allowed but feven notes in mufical com- pofition. Let us now then fuppofc a ftringed infirument fitted up (b) The figure reprefents the infirument with ten chords ; of which fome direft only eight to be tuned unifons, and the two outcrmoft octaves below them.

Such au iiiflrumcui would picbably give us a rcprcfentaiion oC the lyre as it came rirlt Irom the hand of the invcii- tor. This inftrumcut will give us all tiie fcvcn notes following each other, in the ord^rr in whicii any two of thcni will accord together moll plealingly ; but yet it will be a very inconvenient and a very dil'agrecable inllrument : inconvenient, for in a compafs of fcven llriiigs only, the ilrft mull be fcven times as long as the lall ; and difagreeablc, becaufe this firft llring will be fcvcn times as loud alfo ; fo that when the tones arc to be played in a diifcrent order, loud and foft founds Would be intermixed with mofl difgufling alternations. In order to improve the firft inllrument, therefore, fucceeding mulicians very judicioufly threw in all the otlier firings between the two tirfl, or, in other words, between the two O^-laves, giving to each, liowevcr, the fame proportion to w hat it would have had in the firfl natural inflrunicnt. This made the inllrument more portable, and the founds more even and plealing. They therefore difpofcd the founds between the Octave in their natural order, and gave each its own proportional dimcnfions. Of thcfe founds, where the proportion between any two of them is mofl obvious, theconcord between them will be molt plealing. Thus OJtaves, vhich are as two to one, have amolt harmonious effedt ; the fourth and fifth al.o found fweetly together, and they will be found, upon calculation, to bear the fame proportion to each other that Odavcs do. " Let it " not be fuppofed (fays Mr Savcur), tliat the mnlical " fcaie is merely an arbitrary combination of founds ; " it is made up from the confonancc and difTerenccs of <' the parts which corapofc it. Thofe who have often " heard a fourth and tilth accord tf gether, will be " naturallylfd todifcovcr their difference at once ; asd " the mind unites itfclf to their beauties." Let us then ccafe to aflign the coincidences of vibrations as the caufcof harmony, fincc thcfe coincidences in two firings vibrating at ditiercnt intervals, mufl at bell be but for- tuitous ; whereas concord is always plealing. The true caufc why concord is plealing,nuifl aril'e from ou r power, in fuch a cafe, of mcafuring more calily the didcrences of the tones. In proportion as the note can be mea- fured with its fundamental tone by large and obvious diflindions, then the concord is moll plealing ; on the contrary, when the earmeafurcs thedifcriminations of tw^o tones by very fmall parts, or cannot nicafute them at all, it lofcs the beauty of their rcfemblancc ; the whole is tlifcord and pain (c). Bu t there is another property in the vibration of a mu- fical llring not yet taken notice of, and which is alleged to confirm the foregoing theory. If we ftrikeihc ft ring of an harplichord, or any other elaftic founding chord whatever, it returns a continuing found.

Oncof ihebafs- iiotes of an harplichord has been diilectcd la this ma.i- ner by Rair.cau, and the aftual txillcncc of tliefc toucs proved bcyoiul a poliibility of being coiitrovcrrcd. In fact, the experiment is ealily tried ; for if \vc fmaril/ ftrike one of tlie lower ktys of an harplichord, anj then take the finger brilkly away, a tolerable ear will be able to difiinguilii, that, alter the fundamental tone ha» ceafcd, three other Ihrillcr tones will be dillinctl/ heard ; firft the odave above, then tne twelfth, and laflly the feventecnth : the octave above is in general alnioll mixed with the fundamental tone, fo as not tj be ealily perceived, except by an car long habituated to the minute difcrimination of founds. So that wc may obfcrve, that the fmallcft tone isiicard laft,andthc dcepcft and largefl one firft : the two others in order. In the whole theory of founds, nothing has given greater room for fpcculation, conjecture, and difap- pointment,than this amazingpropertyin elaftic firings. The whole firing is uni vcrfally acknowledged to be in vibration in all its parts, yet this linglc vibration re- turns no Icfs than four diiierent founds. They who account for the tones of firings by the,nuinber oftiieir vibrations, arc here at the grcateft lofs. Daniel IJer- nouilli fuppofcs, that a vibrating ftring divides itfclf into a number of curves, each of which has a peculiar vibration ; and though they all fwing together in the common vibration, yet each vibrates w ithin itfclf. This opinion, which was fupported, as moft geometrical fpeculations are, with the parade of dcmonftration, was only born foon after to die. Others have afcribcd this to an elaftic ditlerencc in the parts of the air, each of which, at different intervals, thus received different imprcflions from tiie ftring, in proportion to their cla- fticity. This is abfurd. If wc allow the difference of tone to proceed from the force, and not the frequency, of the vibrations, this difliculiy will admit of an cafy fohuion. Thcfe founds, though they fceni to exift to- gether in the ftring, ailually follow each other in fiic- ceffion : w hile the vibration has greater force, the fundamental tone is brought forward : the force of the vibration decaying, the oftavc is produced, but alraofl only inftantancoudy ; to this fuccecds, with diminilhed force, the twelfth; and, laftly,ihc feventecnth is heard to vibrate with great diflinftnefs,while the thrceother tones are always filent. Thefc founds, thus excited, arc all of them the harmonic tones, whofe difTcrcncts from the fundamental tone arc, as was faid, ftrong, and diftini5t. On the other hand, the difcordaut tones can- not be heard Their differences being but very fmall, they are overpowered, and in a raanncr drowned in the tones offupcrior difference : yet not always neither ; for Daniel Hernouilli has been able, from the fame ftrokc, to make the fame ftring bring out its harnie- nic and its difcordant tones alfo (d.) So ih^t from hence wc may juftly infer, that every note whatfoeve r La is (c j It i-i cci tain, tliat in proportion to the llmplicity of relations in found, the car is pleated with its combina- tions ; but this is not to be admitted as the caufe why mulicians have confined all harmony to an octave. Dif- criminatcd founds,whofe vibrations either never coincide, or at Icall very rarely, do not only ce:'fe to pleafe, b'lt violently grate the ear. Harmony and difcord, therefore, are neither difcriminated by the iudgmcr.: of liearcrs, nor the inftitution of mulicians, but by their own ellcntial and immutable nature. (d) Vid.

A C O U S is only a fuccclTioii of tones ; and that thofc arc mod diflincHy heard, whole dillirciicts are nioft eaiily per- ceivable. To this theory, however, tlioiigh it hns a plaulible appearance, there are ftrong and indeed iiilupcrable objeiMioiis. The very fundamental ptintiplc of it is falfe. Nobody whati-vtr, whether clallic oi' non-e- lafiic, yields a graver fomid by beinj^ (Iruck wi'.h a larger inftiiment, unlcfs cither the founding body, or that pnrt of it which emits the found, is enlarged. In this cafe, the largclt bodies always reiurn the gravtll founds. In fpeaking of claflic and non-elaftic bodies in a nui- fical fenfr, we are not to puih the dillincUon fo far as when we fpcakof them philofophically. A body is w.v- fically elaftic, all of whofe parts arc thrown into vibra- tions fo as to emit a found wlien only part of their fur- face is flruck. Of this kind are bells, nuilicalilrings, and all bodies whatever that are conliderably hollow. — Mulical non-tlaflics arc fuch bodies as cniit a found only from that particular place which is llruck : thus, a table, a plate of iron nailed on wood, a bell funk in the earth, are all of them non-elaflics in a mutical fenfe, though not philofophically fo. When a folid bo- dy, fuch as a log of wood, is llruck with a fwitch,only that part of it emits a found which comes in conta(M ■with the fwitch ; the note is acute and loud, but would be no lefs fo though the adjacent parts of the log were removed. If, inftead of the fwitch, a heavier or lar- ger inflrumcnt is made ufe of, a larger portion of its furface then returns a found, and the note is confe- <)uently more grave ; but it would not be fo, if the large inllrument flruck with a lliarp edge, or a furface only equal to that of a fmall one. In founds of this kind, where there is only a fingle thwack, without any repetition, the immediate caufe of the gravity or acutenefs feenis to be the quantity of air difplaced by the founding body ; a large quantity of air difplaced, produces a grave found, and a fmallcr quantity a more acute one, the force wherev\ith the air is difplaced fignifying very little. — What we here ad- •vancc is confirnud by foine experiments made by Dr Pricdley, concerning the »/;//;c,v.yi/;./) againilobllacles. The lati- tude of pulfe is the rectilineal fpace through which the motion of the air is propagated during one vibration. of the founding body. " All pulfes move equally fall. This is proved by experiment ; and it is fouad that they dcfcribe 1070 I'aris feet, or 1 142 London feet in a fccond, whether the found b= loud or low, giave or acute. " ?. Prob. To determine the latitude of a pulfc. Divide the fpace which the pulfc defcribes in a given time (4) by the number of vibrations performed in the fame time by the founding body, (cor. 1. prop. 24. Simtl's Hfri/foniij), the quotient is the latitude. " M. Sauveur, by fome experiments on organ-pipes, found that a body, which gives the graved harmonic found, vibrates 12 times and a halt in a fccond, and that the Ihrillcft founding body vibrates 51.100 times in a fccond. .^t a medium, let us take the body which gives what S.iuveur calls \\\% fixed found : it performs 100 vibrations in a fecond, and in the fame time the pulfes dcfonbc 1070 Harifian feet ; therefore the fpace dcfcribed by liu pulfes whilll the bwly vibrates once. 86 ACOUSTICS I'ropara- tioii nf Souii 1.

To find the l'rojx>rtion wliiih the grcattll I'/scc, through which the particles of the air vibrate, bears to tlic raJius of a circle, whofc perime- ter is equal to the latitude of the piilfc. " During the firll half of the progrcfs of the claftic fibre, or founding body, it is continually getting near- er to the next particle ; and during the latter half of its progrefs, that particle is getting farther from the fbrc, and thel'c portions of time arc equal [Hcljhum): therefore we may conclude, that at the end of the pro- grefs of the fibre, tlic firft particle of air will be near- ly as far dillant from the tibre as when it began to move ; and in the fame manner we may infer, that all the particles vibrate through fpaces nearly equal to that run over by the fibre. " Now, M. Sauveur { Acad. Science, an. 1 700, />. 1 41 ) lias found by experiment, that the middle point of a chord which produces h'K fixed J'otiiiJ, and whofc dia- meter is ^th of a line, runs over in its fmallcfl fcniible vibrations -,',th of a line, and in its greateft vibrations 72 times that fpace ; that is 72-1-, '^th of a line, or 4 lines, that is, ;d of an inch. "The latitude of the pulfcs of this fixed found is 10.7 feet (5); and llnce the circumference of a circle is to its radius as 710 is to 11 3, the greateft fpace dcfcri- bed by the particles will be to the radius of a circle, whofe periphery is equal to the latitude of the pnlfe as ;d of an inch is to 1.7029 feet, or 20.434S inches, that is, as I to 61.3044. " If the length of the ftringbeincrcafed or dimini Hi- ed in any proportion, crteris paribus, the greateft fpace dcfcribed by its middle point will vary in the fame proportion. For the iniicfting force is to the lending force as the diftance of the ftring from the middle point of vibration to half the length of the ftring [fee Ihlfham and Mar1in\ ; ai:d therefore the int!c(5ting and tending forces being given, the ftring will vibrate through fpaces proportional to its length; but the latitude of the pulfc is inverfely as the number of vibrations performed by the ftring in a given time, (5) that is, direcHy as the time of one vibration, or ilireiflly as the length of the ftring {piop. 24. cor. 7. Smith's Harmonic)) ; therefore the greateft fpace thrcugh w hich the middle point of the ftring vibrates, will vary in the direft ratio of the latitude of the pulfe, or of the radius of a circle whofe circumference is e- qual to the latitude, that is, it will be to that radius as I to 61.3044. " 7. If the particles of the aerial pulfes, during any part of their vibration, be fucceirivcly agitated accord- ing to the law of a cycloidal pendulum, the compara- tive elaftic forces arifing from their mutual aiflion, by wb.ich they will afterwards be agitated, will befuchas will caufc the panicles to continue that motion, accor- ding to the fame law, to the end of their vibration.

Thus will tlie particle E perform its vibrations according to the law of a cy- cloidal pendulum. Prop. 52. B. I. Frincipia. " Let us fuppofc now, tl.at the particles have been fuccclfi\cly agitated, according to this law, for a cer- tain time, by any caufc whatfoever, and let us examine what will be the comparative elaftic forces arillngfrom their mutual adion, by w hich they will afterwards con- tinue to be agitated. " In ihe circumference PITS/i take the equal arches HI, IK, in the fame ratio to the whole circumference which the equal right lines tV, t'G have to BC the whole interval of the pulfes ; and let fall the per- pendiculars HL, IM, KN. Since the points E, F, G are fuccefllvely agitated in the fame manner, and per- form their entire vibrations of progrefs and rcgrefs while the pulfe is propagated from B to C, if PH be the time fnnn the beginning of the motion of E, PI will be the time from the beginning of the motion of F, and PK the time from the beginning of the motion of G ; and therefore Et, ¥ or EF-J-P'^ — E, is equal to EF — LM. But i^ is the expanfion of KF in the placcfc, and therefore this expanlion is to its mean expanfion as EF — LM to EF. But LM is to IH as IM is to OP, and III is to EF as the circumference PIISAis to BC ; that is, as OP is to V, if V be the radius of a circle whofe cir- cumference is BC ; therefore, ex o'qiio, LM is to EF as IM is to V ; and therefore the expanfion of EF in the place Kf is to its mean expanfion as V — IM is to V; and the elaftic force exifting between the phy- fical points E and F is to the mean elaftic force as is to — (Cotes Pneum Led. g.) By the fame V_1M V y ■> Jt arguments, the elaftic force exifting between the phy- fical points F and G is to the mean elaftic force as is to — ; and the difference between thefe V— KN V forces is to the mean elaftic force as IM— KN is to : V— V.IM— V IM— KN .KN-t-lM.KN that is, as is to — ; or as IM — KN is to V ; if on- ly (upon account of the very narrow limits of the vi- bration) we fuppofc IM and KN to be indefinitely Icfs than V. Wherefore, fince Vis given, the difference of the forces is as IM—KN, or as HL — IM (becaufe KH is bifeded in I) , that is (becaufe HL — IM is to IH as OM is to OI or OP, and IH and OP arc given quantities) as OM ; that is, if lybe bifeftcdin. n as nlacc t^ is to its mean cxpanfioii as EK+K^ — E<, or as EV+J>» is to EF, or as \'+/>/ is to V in its re- grcfs ; and its elailic force to the mean clallic force as ' i» to — ; and that the diltcrence of the eladic \+/>t V forces exifling between E and F, and between V and G is to the mean elaflic force as i/j — /;/i is to V ; that is, directly as n^. " Uut this diifcrcncc of the elaftic forces, cxifting be- tween L and F, and between F and G, ib the com- parative clalHc force by which the phylical point » is agitated : and therefore the comparative accelerating force, by which every phylical point in the medium will continue to be agitated both in progress and re- grcfs, will be directly as its diflance from the middle point of its vibration ; and cunfequcntly, will be fucli as will caufc the particles to continue their motion, un- diilurbcd, according to the law ot a cycloidal pen- dulum. Pro/i. 38. 7. I. Ncwtoi. " Newton rejects the quantity + Vxl M+KN-j-IMx KN on fuppolition that IM and KN arc indefinitely lefs than V. Now, although this may be a reafonable hypothelis, yet, that this quantity m;iy be fafely re- jeclcd, will, I think, appear in a more farisfac^ory manner from the following conliderations derived from experiment : PS, in its greateft polliblc iUtc, is to V as I is to 61. 3044 (6) ; and therefore IM or KN, in its greateft pofllble flate, (that is, when the vibrations of the body are as great as polFible, and the particle in the middle point of its vibration) is to V as one is to 122.6. Hence 'V'^' = (5030.76, — VxlM+KN=:24J.2 and IMxKN ^i ; therefore V- is to V— Vxli\t+ KN-)-IMxKN as 15.03076 is to 14.7S656 ; that is, as 61 is to 60 nearly. " Hence it appears, that the greateft; pofTible error in the accelerating force, in the middle point, is the ^S ft part of the whole. In other points it is much lefs ; and in the extreme points the error entirely va- nifhes. " We fliould alfo obfcrve, that the ordinary founds we hear are not produced by the greateft polfible vi- bration of which the founding body is capable ; and that in general IM and KN are nearly cvancfcent with rcfpeft to V. And very probably the difagrceable fen- fat ions we feel in very loud founds, arife not only from IM or KN bearing a fenfible proportion to V, by which means the cycloidal law of the pulfcs may be in fome meafure diOurbed, but alfo from the very law of the motion of the founding body itfclf being difturbcd. For, the proof of this law's being obferved by an e- laftic fibre is founded on the hypothelis that the fpace, through which it vibrates, is indcrliiitcly little with refptS to the length of the ftring. See S/>ulh's Har- monics, p. 21.'!, H.ijhav:, f. 270. " 8. If a particle of the medium be agita'ed, ac- cording to the law of a cycloidal pendulum, the com- parative elaftir force, acting on the iiijaccnt particle, from the inftaiit in which it begins to move, will be fuch as will caufc it to continue its motion according to the fame law. " For let us fuppofe, that three particles of the me- dium had continued to move for times denoted by the arches PK, PI, PH, the comparative elaftic foroc, 3 I'fopaga- tiou of SouD>j>. afting on the fccond during the time of Its motion, would have been denoted by HL — IM, that is, would have been directly at MO (7). And if this time be diminifhed till I becomes coincident w ith P, that is, if you take the panicles in that itatc when the fccond is juft beginning to move, and before the third particle has yet been fct in motion ; then the point M will fall on P, and MO become PO ; that is, the comparative claftic force of the fecond particle, at the i.Ulant in which it begins to move, will be the force with wliich it is agitated in any other moment of time, be- fore the fubfequcnt particle has yet been fet in motion, directly as its diftance from the middle point of vibra- tion. Now this comparative elaftic force, with which the fccond particle is agitated in the very moment in which it begins to move, arifes from the preceding particle's approaching it according to the law of apcu- duliim ; and therefore, if the preceding particle ap- proaches it in this manner, the force by which it will be agitated, in* the very moment it begins to move, will be exactly fuch as (honlJ take plscc in order to move it according to the law of a pendulum. It there- fore fctsout according to that law, and confequently the fubfcqaent eliftic forces, generated in every fuc- celFive moment, will alfo continue to be of the juft magnitude which thould take place, in order to pro- duce fuch a motion. " 9. The pulfes of the air are propagated from founding bodies, according to the law of a cycloidal pendulum. The point E of any elaftic fibre pro- pi„j i ducing a found, may be confidered as a particle of fig. ;. air vibrating according to the law of a pendulum (i). This point £ will therefore move according to this law for a certain lime, denoted by the arch IH, before the fecond particle begins to move ; for found is pro- pagated in time through the fucccflive particles of air (4). Now from that inftant, the comparative claftic force which agitates F, is (8) directly as its diitancc from the middle point of vibration. F therefore fcts out with a motion according to the law of a pendulum : and therefore the comparative elaftic force by which it will be agitated until G begins to move, will continue that law (8). Confequently F will approach G in the fame manner as E approached F, and the comparative elailic force of G, from the inllant in which it begins to move, will be dircdtly as its distance from the middle point of vibration ; and foon in fuccellion: Therefore all the particles of air in the p'llfes fuccelFively fct out from their proper places according to the law of a pen- dulum, and therefore (7) will finilh their entire vi- brations according to the fame law. " Cor. I. The number of p\ilfes propagated is the fame with the number of vibrations of the tremulous body, nor is it multiplied in their progrefs : btcaufe the little phylical line \y, l^fg. 7I as foon as it returns to its proper place, will there quiVfcc ; for its velocity, tvhich is denoted by the line IM, then vanifhes, and its denfity becomes the fame with that of the ambient me- dium. This line, therefore, will no longer move, un- lefs it be again driven forwards by the irapulfc of the founding body, or of the pulfes propagated from it. '• Cor. 2. In the extreme points of the little fpace through w'hich the particle vibrates, the expanlion of the air is in its natural ftatc ; for the expanlion of the phyfical Line is to its natural expanlion as V-i-IMis 10 88 A C O U T I C .Sound.

" lo. To rind the velocity of the pulfes, the den- sity and elaftic force of the medium being given. " This is the 49th prop. B. 2. Newton, in which he Ihows, that whilil a pendulum, whole length is equal to the height of the homogeneous atmofphere, vibrates once forward and backwards, the pulfes will defcribe a fpace equal to the periphery of a circle defcribed with tliat altitude as its radius. "Cor. I. He thence fliows, that the velocity of the pulfes is equal to that which a heavy body would ac- quire in falling down half the altitude of that homoge- neous atmofphere ; and therefore, that all pulfes move equally faft, whatever be the magnitude of t^S, or the time of its being defcribed ; that is, whether the tone be loud or low, grave or acute. See Hales dc Sonii, § 49- "Cor. 2. And alfo, that the velocity of the pulfes is in a ratio compounded of the dircd fubduplicate ra- tio of the elaftic force of the medium, and the inverfe fubduplicate of its denfity. Hence founds move fome- what falter in fummerthan in winter. SccBa/ij de Sonis, p. 141. "11. The ftrength of a tone is as the moment of the particles of air. The moment of thcl'c particles, (the medium being given) is as their velocity ; and the velocity of thcfc pvrticles is as the velocity of the firing which fets them in motion (9). The velocities of two ditfertnt firings are equal when the fpaccs whicli they dcfcribc in their vibrations are to each other as the timesofthefe vibrations: therefore, two dilicrent tones are of equal ftrength, when thefpaccs, through whicli the ftriiigs producing them vibrate, are directly as their vibration. " 12. Let the ftrength of the tones of the two firings AB, CD, which differ in tenfiou only (fig. I, 2.) be equal. Oiiere the ratio of the inflccling forces F and /! From the hypothelis of the equality of the ftrength of the tones, it follows (11), that the fpace GE muft be to the fpace HF as fi to F i,, {^Smith's Han/i. Prop. 24. C'er. 4.) Now the forces inflecting AB, CD through the equal fpaccs GE, HP are to eacli other as the tending forces, that is, as F toyl {Malcolms Trcatir-' 01: Mufic, p. 52.) But the force inflei^ing CD through HP is to tlie force indectingit through HF as HPorGEtoKF, [ib.p. 47.) that is, by the hyp. as f'\, to F ;. Therefore, f.v aguo, the forces infleiiing AB and CD, when the tones are equally ftroug, are to each other as F-f-/i to /+F 4 , or as F 4 to/ ;. That is, the forces neccllary to produce tones of equal ftrength in variousftrings which differ only in tenlion, are to each other in the fubduplicate ratio ot the tending forces, that iSjinverfely as the time of one vibration, or directly as the number of vibrations per- formed in a given time. Thus, if CD be the acute oftave to A B, its tending force will he quadruple that of AB, {Matcolm'i Trtatife on Alr/fic, p. J?) ; and therefore to produce tones of equal jlrength in thefe firings, the force impelling CD muft be doable that iinpeillag AB : aud fo in other cafes. Plate III. " Suppofc, now, that the firings AB, CD, (fig, 2, 3.) ditlcr in length only. The force iiitltciiug Afa through GE is to the tending force, which is given, as GE to AG ; and this tending force is to the force inflecting CD through the fpace HP equal to GE, as HD to HP. Therefore, ex tiblc it is of thefc tremulous iiiotions, the Hrongcr is the found. If the tube be laid on a;iy nou-ilafiic fubftance, it deadens the found, becaufe it prevents the vibratory motion of the pans.

Wc have heard of a very extraordinary echo, at a ruined fortrefs near Loiivain in Klanders. If a pcrfon fung, he only heard his own voice, without any repetition : on the contrary, thofc whollood at fonie diliance, iieard the echo but not the voice ; but then they heard it with furpriling variations, fcunetimes louder, ibmetimes fofter, now more near, then more diltant. There is an account in the memoirs of the French academy, of a limilar echo near Rouen. As (by n° 21 and 22) every point againfi which the pull'es ot founds llrikc becomes the centre of a new fc- ries of pulfes, and found defcribes equal dillances in equal times ; therefore, w hen any found is propagated from a centre, and its pulfes rtrikc agninft a variety of obllacles, if the fum of the right lines drawn from tliat point to each of the obftacles, and from each obliaclc to a fccond point, be equal, then will tlic later be a point in whicli an echo will be heard. " Thus let A be the point from which the found is propagated in all directions, and let the pulfes ftrike Tigainil tlic obfta- cles C, D, E, Y, G, H, I, &c. each of thefc points becomes a new centre of pulfes by the firft principle, and therefore from each of them one feriesof pulfes will pafs through t'.ie point B. Now if the fcvcral fumsof the ri gilt lines. -.t-t-CB, Ah+DB, Ak+^B, AO-i-OB, Afl+HB, rtl-t-lB, &c. be all equal to each other, it is obvious that the pulfes propagated from A to thcfe points, and :'gain from tliefe points to B, will all ar- rive at B at the fame inflant, according to the fccond principle ; and therefore, if the hearer be in that point, his ear will at th» fame inftant be Itruck by all thefc pulfcs. Now it appears from experiment (/!■<.- Av'lfchc/i- Lroek, V. \\. p. 210), that the ear of an exercifcd mu- fician can only dillinguifli fuch founds as follow one another at the rate of 9 or 10 in a fecond, or any (low- er rate : and therefore, for a diftini'l perception of the dirert and rcfleflcd found, there Ihould intervene the interval of ;th of a fecond ; but in this time found defcribes i-i-!-^ or 127 feet nearly. And therefore, unlefs the fum of the lines drawn from each of the ob- llacles to the points A and B exceeds the interval A B by 127 feet, no echo will be heard at B. Since the feveral fums of the lines drawn from the obftacles to the points A and B are of the fame magnitude, it ap- pears that the curve pafTing through all the points C, D, E, ¥, G, H, I, &c. will be an ellipfe, {piof>. 4. B. 1. Ham. Con.) Hence all the points of the obfta- cles which produce an echo, muft lie in the furface of Chap. IV. the oblong fplicroid, generated by ihx: revolution of R-vtrbe- this ellipfe round iis major axis. ruted '< As there may be leveral fphcroids of diticrcnt So""'is. magnitudes, fo there may be feveral oiilcreni t. hocsof " the fame original found. And as there may happen to be a greater number of rcdeciing points in the lurface of an exterior I'pheroid than in that of an interior, a fecond or a third echo may be much more powcrtul thin the tiril, provided that the fuperior number of re- ficctiiig points, th It is, the fuperior number ot rcllce- tcd pulfes propagated 10 the car, be more than fulli- cient to compeiifate for the decay of found which a- rifesfrom its being propagated through a grcatir (pace. This islincly illultratedin the celebrated (chocs at the lake of Killarncy in Kerry,' where tlie hrll return of the found is much inferioi in llrength 10 iliofe wliich immediately fucceed it. " From what has been laid down it appears, that for the molt powerful echo, the founding body Ihould i^e in one fo usof the ellipfe which islhc lection ot the echo- ing fplicroid, and the hearer in the other. However, an echo may be heard in other liiuations, though not lo favourably , as fuch a number of retlcctecl pulfcs may arrive at the fame time at the ear:;s may be fufiicicnt to excite a difiiiicl perception. Thus a pcrfon often hears the echo ol his own voice ; but for this purpofc he flinuld ftand at Icall 63 or 64 feet from the refiecl- ing obll cle, according to what has been (aid before. At the common rate of fpeaking, we pronouuce not above three fyllables and an half, that is, fcvcn half fyllables in a fecond j therefore, that the echo may re- turn juft asfoon as three lyliables are exprclFcd, twice the diftance of the fpeaker from the reflecting objeft mult be equal to 1000 feet ; for, as found defcribes 1 1(]2 lect in a fccond, *ths of that fpace, th^t is, 1000 feci nearly, will be defciibed while fix half or three whole fyllables are pronounced : that is, the fpcaker muft ftand near 500 feet from the obftacle. And in general, the diftance of the Ipeaker from the echoing furfate, for any nunbtr of fyllables, muft be equal to the fcvemh part of the product of 11 42 feet multiplied by that number. " In churches we never hear a diftinct echo of the voice, but a confufed found when the fpeaker utters his words too rapidly ; bccaufc the grtatcft difference of diftance between the direft and relieded courfes of fuch a number of pulfes as would produce a diilincl found, is never in any church equal to 127 feet, the limit of echoes. " But though the firft reflefted pulfes may produce no echo, both on account of their being too few in number, and too rapid in their return to the ear ; yet it is evident, that the rerie6l.ing furface may be fo formed, as that the pulfes which come to the ear after two retleilions or more may, after having defcribed 1 27 feet or more, arrive at the ear in fufficient numbers, and alfo fo nearly at the fame inftant, as to produce an echo, though tiie diftance of the refieiting furface from the ear be lefs than the limit of echoes. This is confirmed by a fingular echo in a grotto on the banks of the little brook called the Dianan, about two miles from Caftlccomber, in the county of Kilkenny. As you enter the cave, and continue fpeaking loud, no re- turn of the voice is perceived : but on your arriving at Chap. IV.

ACE a concave mirror of about two feet diameter, as AB (g), ina perpendicular dircftion. Thefocusof this mirror may be at 15 or 18 inches diftancc from its furface. At the dillance of about five or fix feet let there be a partition, in which there is an opening E F, equal to the fize of the mirror: againll this opening mud be placed a picture, painted in water- colours, on a thin cloth, that the found may eafily pals through it ( h). Behind the partition, at the dillance of two or three feet, place another minor G H, of the fame lizc as the former, and let it be diametrically oppolite to it. At the point C let there be placed the figure of a man fcated on a pedeftal, and let his car be placed ex- »cHy in the focus of the firft mirror : his lower jaw muft be made to open by a wire, and lliut by a fpriag ; and there may be another wire to move the eyes : thcfe wires mull p ifs through ihe figure, go under the floor, and come up behind the partition. Let a perfon, properly inllrudled, be placed behind the partition near the mirror. You then propofc to any one to fpeak foftly to the flatuc, by putting his mouth to the earof it, alluring him that it will anfwer inflanlly. You then sjive the fignal to the perfon be- hind the partition, who, liy placing his ear to the fo- cus I, of the mirror G H, will hear dillindly what the other faid ; and, moving the jaw and eyes of the ftatuc by the wires, will return an anfwer diredly, which will in like manner be diftinclly heard by the firfl fpeakcr. This experiment appears to be taken from the Century of Inventions of the Marquis of Worccf- ter ; whofc defigns, at the time they were publiilicd, were treated with ridicule and nealeil as being im- prafticablc, but are now known to be c;cnerally, if not univerfally pradicablc. The words of the Marquis arc thefe : " How to make a bra/.en or Hone head in t .e midll of a great held or garden, fo artificial and natu- ral, that though a man fi'.cak cvci fo W.i\j, r\X even E::t:rtai;i- whilptr into iliccar ihtrcot, it willprclciitly open its n't '-xpt"- nicuth, and refolve the quciiioii iu Ficnch, Latin.

II. Let there be two headsofplallcrofl^aris, placed 18 on pedellals, on the oppolite (ides of a room. There Tlie com- muil be a tin tube of an inch di.n:netcr, tiiat mufl pafs m«n"-"ati»c front tlie ear of one-head, through the pcdeflal, linJcr **" the floor, and go up to the mouth of the other. Ob. fcrvcjthat the end of the tube whi:h is next the earof the one head, ihoiild be conliderably larger than that end which comes up to the mouth of the other. Let the whole be fo difpofcd that there may not be the leall fuipicion of a communicaiion. Now, when a perfon fpeaks, quite low, into the ear of one bull, the found is reverberated thro' the length of the tube, and will be diftinclly heard by any one who fliall place his ear to the mouth of the other. It is not neceilary that the tube fhould come to the lips cf the bull if there be two tubes, one going to the ear, and the other to the mouth, of each head, two pcr- fons may converfe together, by applying their mouth and ear recriprocally to the mouth and earof the bufl ; and at the fame time other perfons that lland in the middle of the chamber, between the heads, will not hear any part of their convtrfiition. . III. Place a bufl on a pedcflal in the corner of a TheOracu- room, and let there be two tubes, as in the foregoing br Head, amufement, one of which mud go from the mouth and the other from the ear of the bull, through the pedeftal, and the fioor, to an under apartment. There may be likewifc wires that go from the under jawand the eyes of the bull, by whicii they may be ealily moved. A perfon being placed in the under room, and at a fignal given applying his car to one of the tubes, will hear any qiiellion that is aflce.d, and immediately re- ply ; moving at the fame time, by meansof the wires, the mouth and the eyes of the bufl, as if the reply came from it. ^g IV. In a large cafe, fuch asisufed for dialsandfpring A SolirS<». clocks, the front of which, or at Icafl the lower part of "ati. it, nuifl be of glafs, covered on the iniide with gauze, let there be placed abarrel organ, which, when wound up, is prevented from playing, by a catch that takes a toothed wheel at the end of the barrel. To one end of this catch there muft be joined a wire, at the end of which there is a flat circle of cork, of the fame dinien- fion w ith the iiifide of a glafs tube, in which it is to rife and fall. This tube mull communicate w ith a reUr- voir that gocsacrol\ the front part of the bottom of the cafe, which is to be rilled with fpirits, fuch as \% ufed in M 2 thcr.

An experiment ot this kind may be performed in a fieid or garden, between two hedtres in cne ot which the mirror All may be placed, and in the other an oi^enin^ aritully contrived 92 ACOUSTICS Entertaiii- ingHipcri- menfs, 'Jft. 31 Automa- mus Harp- fichord. theniiunittcrs, but not culourtd, iliat ii may be tlic belter concealed by the gauze. This cai'e being placed in the fun, the fjurits will be rarefied by the heat ; and riling in the tube, will lift up ihe catch or trigger, and let the organ in play : rvhicli it will continue todo as long as it is kept in the fiin ; for (he fpirits cannot run out of the tube, that part of the catch to which the circle is tixcd being prevented from riling beyond a certai n point by a check placed over it. When the inachincc is placed againfl the fide of a room on which the fun fliines ftrong, it may conllantly remain in the fame place, if you iiulofc it in a fecond cafe, made of thick wood, and placed at a little di- itanccfrom the other. When you want it topcrform, it will be only neceiTary to throw open the door of the outer cafe, and expofeit to the fun. But if the machine be moveable, it will perform in all feafons by being placed before the hre ; and in the winter it will more readily (lop w'htn removed into the cold. A machine of this fort is faid to have been invented by Cornelius Dreble, in the lad ceiunry. W hat the conrtruftion of that was, vvcknow not ; it might very likely be more complex, but could fcarce anfwer the inicntion more readily. V. Under the keysofa common harpfchord let there be fixed a barrel, fomething like that in a cham- ber organ, wiili flops orpinscorrefpondingto the tunes you would have it play. Tliefe llopsmnft be moveable, io that the tunes may be varied at pleafurc. Krom each of the keys let there go a wire perpendicular down : the ends of thefe wires mull be turned up for about one-fourth of an inch. Behind thefe wires let there be an iron bar, to prevent them from going too far back. Now, as the barrel tuins round, its pins take the ends of the wires, which pulldown the keys, and play the harpfichord. The barrel and wires are to be all inclofed in a cafe. In the chimney of the fime room where the harpfi- chord flaiuls, or at leaA in one adjacent, there niufl be a fmoke jack, from whence comes down a w ire, or cord, that, palling behind the wainfcot adjoining the Chap. IV. chimney, goes under the floor, and up one of the legs Entortain- of the harjilichord, iuio the cafe, and round a fuuill iiigcx|HTi- w heel fixed on ilic axis of that tirll mentioned. There mcnts, t5V. Ihould be pullies at different diltanc-s, behind the " ' waiufcot and under the floor, to facilitate the motion of the chord. This machinery may be applied to any other keyed inflrumcnt as v,'ell as to chimes, and to many otiier purpofcs where a regular continued motion is re- quired. An inllrunient of this fort may be confidered as a perpetual motion, according to the vulgar accepta- tion of the term ; tor it will never ccafe going till t];c fire be extinguilhed, or fonie parts of the machinery be worn out. VI. Ar the topofa fummcr-houfe,orothcrbnilding, a Vcntofal let the wind-wheel B (of wliich A is an horizontal Symphony, fcction,) be on the upper end of the perpendicular Pl^t« '• axis K ; on the lower end of which is fixed tiie pini- %• ^' on C that takes the toothed wheel D on the axis of the great wheel E — The perpendicular axis F goes down very near the wall of the room, and may be covered after the fame manner as are bcU-wircs. In the great wheel there niufl be placed a num- ber of if ops, correfpouding to the tunes it is to play. Thefe Hops are to be moveable, that the tunes may be altered at pleafure. Again ll this wheel there mufl hang 12 fmall bells, anfwering to the notes of the ga- mut. Therefore, as tiie wheel twrns round, the flops flrikingagainll the bells, play 'hefevcral tunes. There ihould be a fly to the great wheel, to regulate its mo- tion when the wind is flrong. The wheel E, and the bells, arc to be inclofed in a cafe. There may be feveral fets of bells, one of which may anfwer to the tenor, another to the treble, and a third to the bafs ; or they may play different tunes, ac- cording to the (ize of the wheel. As the bells are fmall, if they arc of lilvcr, their tone will be the more plealirig. Inflcad of bells, gkfTes may be here ufed, fo difpo- fcd as to move freely at the flroke of the flops. This niacliinery :nay likewife be applied to a barrel-organ ; and to many other ufes. ACQ, ACQ_S, a town at the foot of the Pyrenxan moun- tains, in the government of Kuix in France.

In the year before Chrift 3S4, the people of Gcla built Acragas, 108 years after building their own city. It took its name from the river running by it ; and be- ing but two miles from, enjoyed all the conveniences that (liuuld come by, the fea. It was a place of great flrcngth, flanding on the top of a very fleep rock, and wadied on the fouth lide by the river Acragas, now called Fiume di Cergeiiti, and on the fouth-vveft by the Hypfa, with a citadel to the fouth-eaft, externally fur- rounded by a deep gulf, which made it inaccc!!il)lc but on the lide next the town. It was famous for the ty- rant Phalaris and his brazen bull. They were a peo- ple luxurious in their tables, and magnificent in their dwellings ; of whom Empedocles, in Diogenes Laer- tius, fays, that they lived to-day as if they were to die to-morrow-, and built as if they were to live forever.

It was very famous in the time of the eruladocs, and un- derwent fevcral lieges both by the Chriltians and Sa- racens. It is lituated at the north angle of a bay, which extends in a femicircle of three leagues, as tar as the point of Carmcl. During the Crufades, the poUeflion of this town was long difputed by tlie Chriliians and Saracens. In 1 192 it was taken from the latter by Richard I. of England and Philip of France, who gave it to the knights of St John of Jerufalem, who kept poirelTioii of it 100 years, when it was retaken by the Saracens, and almoll entirely deftroyed. This event is rendered memorable by an ad of lingular rcfolution with which it was accompanied. A number of beautiful young nuns, terrified at the profped of being cxpofed to the brutal laft of the infidels, determined to avoid the vio- lation of iheir challity, by rendering themfelves ob- jeds of avcrl'ion. With this view they cut off their nofes and mangled their faces. The Saracens, inria- med with refentment at a fpcftacle which prevented the gratification of their appetites, immediately put them all to the fword. After the expullion of the crufaders, it remained almoll dcfertcd ; but in our time h.is again revived by the injuilry of Dalier ; and the works creded by Djczzar, within the lall ten years, liavc rendered it one of the principal towns upon the coafb. The mol'que of this Pacha is boafled as a ma- flerpiece of eaftcrn taftc. The bazar, or covered mar- ket, is not inferior even to thofe of .Aleppo ; and its public fountain furpalles in elegance thofcof Damafcus, though the water is of a very iudifl'erent quality. The Pacha has derived the more honour from thcfe works, as he was himfclf both the engineer and architcd : he formed the plans, drew the dcligns, and fupcrin- tcndcd the execution. The port of Acre is one of the beft fiiuated on the coaft, as it is Iheltered from the north and north-weft winds by the town itfelf ; but it is greatly choaked up fince the time of Fakr-el-din. Djczzar has contented himfelf with making a landing-place for boats. 1 he fortifications, though more frequently repaired than any other in all Syria, are of no importance : there are only a few wretched low towers, near the port,, on which cannon arc mounted ; and ihefc rufty iron pieces are fo bad, that fome of them burft every time they are fired. Its defence on the land lide is merely a garden-wall, without any ditch. Corn and cotton form the bafis of the commerce of Acre, which is becoming more tlourilhing every day. Of late, the Pacha, by an abufe common throughout all the Turkilh empire, has monopolized all the trade in his own hands ; no cotton can be fold but to him, and from him every purchafe inuft be made. In vain have the Europc '"''■ *^'' ble for the fqualid colour of their wings. So great was the number of thefc infects, that they were the only fuftcnancc of the barbarians, who :00k them in the fol- lowing manner: At the diftance of fomc ftadia from their habitations there was a wide and deep valley. They liUed this valley w ith wood and wild herbs, with wiiich their country abounded. When the cloud of locufts appeared, which were driven on by the wind, they let lire to the fuel which they had collected. The fmokc which arofc from this immenfc fii e was fo thick, that the locufts, in crofling the vallty, were fti.led by it, and fell in heaps on the ground. The paiTage of the locufts beingthus intercepted for many days, they made a large proviiion of thofe iiifefts. As their coun- try produced great quantities of lalt, ihcy falted them, to render them more palatable, and to wake them keep till the next feafon. This peculiar fupply was their fole food : they iiad neither herds nor llocks. They were unacquainted with tifliing; for they lived at a dif- tance from the fea. They were very active, and ran with great fwiftnefs. But their life was not of long duration; it exceeded not forty years. The clofc of their life was extremely miferablc ; for in their old age, winged lice of different, but all of ugly forms, bred in their bodies. This malady, which began in the 5reaft and belly, foon fpread through the whole frame. The patient at tirft felt an itching ; and the agreeable fen- iatiou produced by his fcratching of hirafelf, preceded a moil deplorable calamity. For when thofe lice, which had bred in his body, forced their way out, they cauftd efflifions of corrupt blood, with cxcrncia- ting pains in tlie ikin. The unhappy man, with la- mentable cries, was induftrious himfelf to make paf- fages for them with his nails. In fliort, thefe lice if- fued forth facccflivcly from the wounds made by the hands A C R [ 95 ] A C R Acrido- hinds of the patient, as from a veflcl full of holes, and P*"t''- in fiich niinibtrs that it \vas impoiiiblc to exterminate ' ' tliem. — \V liether this extraordinary and dreadful dif- tcnipcr was occafmncd b) the food of the inhabita.iis of this country, o- by a pcilciiiial quality oi tlieir climate, it is diincull tn dtieriiiinc. Indeed, as to the credibility ot' the whole account, we mull leave the rsa.lcr to judge. But though the circumftanccs of thcfe people (liould be deemed fabulous, yet may the acrtdophj^:a be true. It is well known, that to this day the iuhauiiaiits of Ethiopia, /\rabii, &c. frequently ufe locurts as lood.

Ic Grand tiie priutipal French interpreter at Cairo, and others, that a famine frequently rages at Mecca when there is a fearcity of corn in Kgy pt, which obligi s the inhabitants to live upon coarfcr food than orninary : That when corn is fcarce, the Arabians grind tiic lo- cufts in hand-mills, or flone-mortars, and bake them into cakes, and ufe thefe cakes in pl.icc of bread : That he has frequently feen locults ufed by ilie Ara- bians, even when there was no fearcity of corn ; but then they boil them, (lew them with butter, and make them into a kind ot fricalTee ; which he fays is not dif- agreeably tailed, for he had fome'.imes tailed thcfe lo- cull-fricaiFcesout of curiofity. • Vcyart to '^ later traveller, Dr Sparrman, informs us *, the Cafe, " That loculls fomctimcs atfbrd a high treat to the vol.l.p.36. more unpoliihed and remote hordes of the Hottentots; when, as fomctimes happens, after an interval of 8, 10, 15, or 20 years, they make their appearance in incredible numbers. At thefe times they come from the north, migrating to the foiithward, and do not fuf- fer themfelves to be impeded by any obftacles, but fly boldly on, and are drowneo in the fea whenever they come to it. The females of this race of infects, which are moll apt to migrate, and are chietly eaten, are faid not to be able to riy ; partly by reafon of the ihortnefs of their wings, and partly on account of tlieir beinj heavy and diftended with eggs ; and ihort- ]y after they have laid thefe in the land, they arc faid to die. It is pirticuLirly of thefe that tlie f lottentots make a brown cotfee-coloured foup, which, at the fame time, acquires from the eggs a fat and greafy appear- ance. The Hottentots are highly rejoiced at llie ar- rival of thefe loculls, though ihey are fire to dedroy every bit of verdure on the ground : but the Hotten- tots make themfelves ample amends for this lofs, by falling foul on the animals ihcniftlves, eating them in fuch quantities as in the fpace of a few days to get AcriCui vilibly fatter and in belter condition than before." I The Aobi Poirct, alio, in this Memoir on the Infecls Aciobatica of Barbary and Numidia, informs us, " That the '^~~' Moors make loculis a part of their food ; that they go to hunt them j iry thci.i in oil and butter ; and fell them publicly at i uiiis, at Bonne," &c. From thtfe accounts, we may fee the folly of that difpute among divines about the nature of St John"* fooo in the wiluernefs : fome maintaining the origi.ir.1 word to lignify the fruits of certain trees ; others, a kind of birds, &c. : but thofe who adhered to the li- teral meaning of the text were at leaft the molt ortho- dox, although their arguments were perhaps not fo ilrong as they might have been, had thiy hid an op- portunity of q loting fuch authors as the above.

ACROAMATIC, or Acrcatic, in general, de- notes a tiling f iblime, profound, or abftrufe. ACROAAIATICI, a denomination given the dif- ciples or followers of Arillotle, &c. who were admit- ted into the fecrcts of the inner or acroamatic philo- fophy. ACIIOA riC. Ariftotles leaures to his difciples were of two kinds, ixotnU- and airoatic. The acruatic were thofe to which only his own difciples and inti- mate friends were admitted ; whereas the exoteric were puLlic, and open to all. But there are other dif- ferences. The acroatic were let apart for the higher and more ab.lrufc fubjeds ; the exoteric were employ- ed in rhetorical and civil fpeculaiions. Again, the acroatics were more fubtile and exact, evidence and demonllration being here aimed at ; the exotericschief- lyaimedat the probable andplaulible. The former were the fubjecl of the mornings exercifesin the Lyceum, the latter of the evenings. Add, that the e.xoicrics were pLiblilhed : whereas the acroatics were kept fe- cret ; bcingeiihcr entirely conce.-iled ;or, if they were publiflied, it was in fuch obfcurc terms, that few but his own difciples could be the wiftr for them. Hence, when Alexander complained of his preceptor for pub- lilhing his acroatics, and thus revealing what liiould have been refervcj to his difciples, Ariltotleanfwercd that they were made public and not public ; for that none who had no: heard them explained by the author viv^t voce, would underlland them. ACROATflOUM, or Acrothoum (anc. geog.), a town lituated on the top of inoant Athos, where the inhabitants, according to Mela, were longer lived by half than in any other country : called by the modern Greeks, Ayior tftc; by the Italians, La Cima Ji.Mciili Santo.

ACRONIUSlacus, (Mela) ; a fmall like formed by the Rhine, foon after its rife out of the ^Ips, and after palling the greater lake at Coullanee, called / V- «;/./, and now the Boimgec, or lake of Coullanee. ACROPOLIS (anc. geog.), the citadel, and one of the divilions of Athens ; c::llcd Fo//;, becaufe eoii- flituting the firfl; and criginal city ; and the Upfier Po- lls, to diiliaguifh it from the Lower, which wasafter- wards built round it in a large open plsin, the Acro- polis Handing on a rock or eminence in the heart of this plain ; and hrnce its name : To ihe north it had a Acropollii wall, built by the I'clafgi, and therelorc called / claf- || gk ; and to the fouth a w all, by Cy mon the fou of Mil- Acrofto- tiadcs, out of the Pcrfian fpoils, many ages after the . ''""'• . building of the north wall. It had nine gates, and was therefore called Eiirieapy)oii ; yet but one princi- pal gate or entrance, iltc afcent to w hich was by a riiglit of (leps of white marble, built by Pericles with great magniiicencc, (Plutarch). ACROPOLITA (George), one of the writers iti the Byzantine hiilory, was born at Conllantinople, in the year 1220, and brought up at the court of the em- peror John Ducas at Nice. He was employed in the moll important atiairs of the empire ; being fent am- ball'adof to Larill'a, to cllablilh a peace with Michael of Kpirus ; and was conllitutcd judge to try Michael Conincnus, fufpefted of engaging in a confpiracy. Theodorus Lafcaris, ihp fon of John, whom he had taught logic, appointed him governor of all the wcllern provinces in liis empire. IniajJ, he was taken pri- ibncrina war with Michael Angelas : but gaining his liberty in 1260, by means of the emperor Palaologus, he was fent by him ambalfador to Conilantine, prince of Bulgaria; and was employed infeveral othernego- ciaiions. He wrote, A Continuation of the Greek Hi- ilory, from the taking of Conllantinople by the Latins till it was recovered by Michael Pal*ologus in 1261, which makes part of the Byzantine hiilory ; A Trea- til'e concerning Faith, Virtue, and the Soul ; An Fx- polition of the Sermons of St Gregory Nazianzcn and other pieces. Gregory Cyprian, patriarch of Con- flantinople, in his encomium upon him, prefixed to Acropolita's hiftory, is perhaps foinewhat extravagant in his praifc, when he fays he was equal lo Ariliotlc in philofophy, and toPlatoin tlie knowledge of divine things and Attic eloquence. ACROSPIRE, a vulgar term for wliat botaniflscall the //f/CTi". See the article Plants. ACROSPIRED, in malt-making, is the grain's fliooiing both at the root and blade end. ACROSTIC, in poeti-y, a kind of poetical compo- fition, difpofed in fuch a manner, that theinitiallettcrs of the verfes form the name of fome perfoii, kingdom, place, motto, Sec. The word is compounded of the Gj'cek, sotoQ^i-.v/r.-w//^, and annx^j-jerft:. The acroflic is conlidercdby the critics as a fpeciesof falfe wit, and is tlierefore very little regarded by the moderns. ACROSTICUM, RusTVBACK, Wall rue, or FoRK-iERN, in botany, a genus of the cryptogamiri tilices. The frudifications arc accumulated on the whole inferior furface of the frond, fo that they every- where cover it. There are upwards of ;;o fpecics ; but only three of them (according toothers, two) arc natives of Britain, viz. the fepientrionalc, or horn- ed fern, wliich grows on walls or clifts of rocks ; the ilvcnfe, or hairy {trn, growing in clifts of rocks ; and the thclyptris, or marlhfern, in tufty bogs. ACROSIOLIUM, in ancient naval architeflurc, the extreme part of the ornament ufcd on the prows of their lliips, which was fomctimes in the Ihapc of a buckler, helmet, animal, &c. ; but more frequcnily cir- cular, or fpiral.

They nfually contrive the Auto tofall on fome great felliv. 1, that the execution may pals with the more awe and regard ; at Icafl it is ahvay s on a Sunday. The Auto da Vc may be called the lad art of the inqiiilitorial tragedy; it is a kind of goal-delivery, ap- pointed as oft as a competent number of prifoners in the inquifuion arc convirted of herify, cither by their own vohuuary, or extorted confellion, or on the evi- dence of certain witnelFcs. The procefs is thus: in the morning they arc brought into a great hall, where they have certaiuhabitsput on, which they are to wear in the proccflion. The procellionis led up by domini- can friars ; after which come the penitents, fome with fan-bcnitoes, and fome without, according to the na- ture of their crimes ; being all in black coats without llceves, and bare-footed, with a wax-candle in their hands. Thcfc are followed by the peaiients who have narrowly clcaped being burnt, who over their black coats have flames paintcdwith their points turned down- wards, Fiiego icvilto. Next come the negative, and relapfed, who are to be burnt, having flanici on their habitspointingupwards.

After the prifoners, comes a troop of tamiliars on horfcback ; and after them the inquilitors, and other othcers of the court, on mules ; lali of all, the inquilitor-general on a white hvrfe, led by two ir.t.i with black hats and green hat bands. A fcalFoid is crertej in the Tcrriero dc I aio, Ww cnnnvh fortwoov thrte ihojfand peojilc; atone cudofwhich are the prifoners, at the other the inquilitors.

The prifoners being thus in i lie hands oftheti*ilmagiftra!c,arcpre(enily ii.aded with chains, and carried iiril to tlic fecuLnr goal, and from thcn^c i.i an hour or two brought bcl'ore tlie civil jiulgc ; who, alter alking in what religion they intend to die, pro- nounces linteuce, on fuch as declare they die in t'lC communion of the church of Rome, that they (hall be firft ilrangied, and then burnt to alhcs ; on fuch as die in any other faith, that they be burnt alive, lloth arc immediately carried to tlic Riiitra, the place of exe- cution ; where there are as many Hakes fci up as there areprifoners to be burnt, with a quantity ofjry furz a- bout them. The (lakes of the profelfed, thai is, fuch as perlilt in their hercfy, are alout four yards high, having a fiiiall board towards the top for the priloncr to be fcatcd o*!. The negative and relapfed being firft ffrangled md burnt, the profetfed mount their (takes by a ladder ; and the Jefuits, after feveral repeated ex- hortations to be reconciled to the church, part with them, telling them they leave them to the devil, who is flanding at their elbow to receive their fouls, and carry them with him into the tlamcs of hell. On this a great iTiout is raifed; and the cry is. Let the dogs b.nrdi bt viad: ; which is done by thrulling flaming furzes faftcned to long poles againfl their faces, tifl their faces are burnt to a coal, which is accompanied with the loudc/l acclamations of joy. At lail, lire isfet to the furz at the bottom of the Hake, over which the profcfredarc-cliaincd fo high, that the topoftherianic feldom reaches higher than the feat llicy (iton ; foiliat they rather feem rcafted than burnt.

Act, in dramatic poetry, ligniiics a certain divi- fion, or part, of a play, deligncd to give fome rcfpitc both to the artors and Ipcrtaiors. The Romans were the tirfl who divided thtir theatrical pieces into srts ; fer no fuch divilions appear in the works of the lirll dramatic poets. Their pieces indeed eonfilled of feve- ral parts or divilions, which they called prr^iafu, epi- tafii, ciitiijlalh, and iatajlriphe ; but thefedivifions were not marked by any real interruptions on the theatre. Nor does Aridotle mention any thing of arts in his Art of Poetry. But, in tli« time of Horace, all regular and finidicd pieces were divided into five a.ls.

Thefe edifts were generally exprelfed in fuch terms as thefe : " The au- gull emperors, DiocUfian and I\Iaximian, in council de- clared. That the children of Decurions ihould not be cxpofed to wild bcalls in the amphitheatre." The fenate and folditrs often fwore, either through abjeftllatteryor by conipulfion, upon the edifis of the emperor, as wc do upon tiie bdlc. And the name of Jfidiui Msrula waserafed by Nero out of theregiller of fenators, becaufe he rcfuftd to fwcar upon the edicts of the emperor Auguflus. Acta Diuma, was a fort of Roman gazette, con- taining an authorized narrativcof the traulaftions wor- thy of notice which happened at Rome. Petronius has given us a fpccimen of the a[]a diurna in his account of Trimalehis; and as it may not perhaps be unenter- taining to fee how exaftly a Roman newfpaper runs in the flyle of an American one,the following is an article or two out of it : " On the 26th of July, 30 boys and 40 girls were born at Trimalchi's eilate at Cuma. " At the fame time a (lave was put to death for ut- tering difrcfpectful words againfl his lord. "Thefanic day a fire broke out in Pompey's gardens, which bcganin the night, in the Iteward's apartment." JcTAl'upiili, among the Romans, were journals or regifters of the d:tily occurrences ; asafl'cmblics, triiJs, executions, buildings, births, marriages, deaths, &c. of illurtrious perfons, and the like. Thefe were other- wife called /^il;i Piiblica, and ABaDiuniu, or limply Ada. The Alia differed from Annals, in that only the greater and more important matters were in tlie latter, and thofc of Icfs note were in the iormer. Their origin is attributed to Julius Cxfar, who firfl ordered the keeping anJ making public theactsof the people. Some trace them higher, to ServiusTullius ; who, to difcovcr the number of perfons born, dead, and alive, ordered that the next of kin, upon a birth, fliould put a certain piece of money into the treafury of Juno Lu- cina ; upon a death, into that of Venus Libitina: the like was alfo to be done upon alliiniing the toga virilis, &c. Under Marcus Antoninus, this was cari-ied fur- ther : perfons were obliged to notify the births of tlu ir children, with their names and furnamcs,thc day,con- f.il, and whether legitimate or fpurious, to tlie praifciils of the JErarimii Suturin, to be entered in the public afls ; though before this time the births of perfons of quality appear thus to have been regillered. Acta Senatus, among the Romans, were minutes of what palled and was debated in the fenate-houfc. Thefe were alfo called Conwientarli, and by a Greek name tj^ufit^ixtTa.. They had their origin in the con- fulfiiip of Julius Cacfar, who ordered them both to be kept and j sblilhcd. The keeping them was continued under Augullus, but the publication was abrogated. Afterwards all writings, relatingtothedccrces orfcn- tcnccs of the judges, or whatpalfed and was done be- fore them, or by their authority, in any eaule, were alfo called by the name Acia : Jn which fenfe wc read of civil adfs, criminal afts, intervcnient afts ; ada ci- vilia, cri7nii:alia, iiitcrvciiieiitia, &c. Piil'/ic Acts. The knowledge of public ai51s forms part of a peculiar fcience, called the Diplomatic, of great importance to an hilforian, ilatefman, chro- nologcr, and even critic. The prefervation of them was the firft occafion of ereding libraries. The flyle of aifls is generally barbarous Latin. Authors are di- vided as to the rules of judging of their genuiiienefs, and even whether there be any certain rule at all. F. Germon will have the greater part of the ai^s of former ages to be fpurious. Fontanini aflerts, that the num- ber of forged afts now extant is very fm'all. It is cer- tain there were fcvere punilliments inflicf ed on the for- gers and faUiliers of ads. — The chief of the Englilli- a<5ts, or public records, are publiflied by Rymer, under the title of f^ri/i'r^, and continued by Saunderfon ; an extraclwhereof has been givcnin French byRapin,and tranHatcd into Englilh under the title of Acta Regia. Great commendations have been given this work : alfo fome cxceptionsmade to it ; as thatthereare many fpu- rious a'^is, as w ell as errors, in it ; fome have even char- ged it with falfifications. — The public afts of France fell into the hands cf the Englilh after the battle of Poitiers, and are commonly faid to have been carried by them out of the country. But the tradition is not fupported by any fujHcient teflimony. Acts 'jfih; Apopies, one of the facred books of the NewTcilament, containing the hiftoryof the infant- church, during the fjuce of 29 or 50 years from the afccnlion of our Lord to the year of Chrili;6 5. — It was written by St Luke ; and addreffed to Theophilus, the perfon to whom thecvangelill had before dedicated his gofpcl. Weherefind theaccomplilhmentoffeveralof the promifesmade by our Saviour; his afccnfion ; the defccntofthe Holy Cihofl; the firft preaching of the a- po;Hcs, and the miracles whereby their doctrines were confirmed ; an adniirablepidureof the manners of the primitive Chriftians ; and, iii Ihort, every thing that palFedin the church till the uifperfion of the apoliles, who fcparuted themfelvcs in order to propagate the gofpel throughout the world. From the period of that feparation, St Luke quits the hiftory of the other apo- flles, who were then at too great a diftancc from him, and confines himfclf more particularly to that of St Paul, who had chofen him for the companion of his labours.

The llylc of this work, which was originally compofcd in Greek, is much purer than thatof tlic other canonical writers j and it is obfcrvable, that St Luke, who was nuich better acquainted with the Greek than with the Hebrew lan- guage, always, in his quotations from the OKI Tella- nient, makes ufc of the Scpluagint verfion.

Acts oj Pilate ; a relation fcnt by Pilate to the em- perorTiberius, concerning Jefus Chrift, his death, re- furrcflion, afcenfion, and the crimes of which he was convicted before himf . It was a cuftom among the Romans, that the proconfuls and governors of provin- ces (hould drawup ails or memoirs, of what happened in the conrfeof their government, and fend them to the emperor and fcnate. The genuine a(ts of Pilate were fentby him to Tiberius, who reported tlicm to the fc- nate ; but they were reje(5lcd by that afl'cnibly, btcaufc not immediately addrelfed to them : as is tcitificd by Tertullian, in his Apol. cap. j. and 20, 21. The heretics forged ads in imitation of them : in the reign of the emperor Maximin, the Gentiles, to throw an odium on tlie Chriftian name, fprcad about fpurious Afts of Pilate ; which the emperor, by a folcmn edict, ordered to be fent into all the provinces of the empire, and enjoined the fchool-uiafters to teach and explain them to their fcholars, and make thera learn them by heart. Thefc a,.1s, both the genuine and the fpurious, are loft. There is indeed extant, in the Pfeudo-Hcge- fippas, a letter from Pilate to the emperor Claudius, concerning Jefus Chrift J ; but it difcovers itfelf at firft fight not to be authentic.

Tlie «rs//<7 confi;ls of four petals, larger than the calyx, pointed at both ends, and falling otf. '1 be jlamiua conlill of numerous capillary filaments ; the anihera are roundiih, crcft, and didymous. The pifiilium has an ovate germ.cn j no ftylas ; the fligina thickilli and obliquely dcprcdcd. The pericarpium is an oval fniooth one-furrow'd one-ccU'd berry. The feeds are very numerous, fcmiorbicular, and incumbent in a double order. — This genus is alFociattd with the Muliijitiqtia, the 26"" natural order. There arc four Species and properties. I. The fpicata, or common hcrb-chriftophcr,is a native in fcveral parts of Britain. It grows to the height of about two feet and a half ; the foot-ftalks of the leaves arifc from the root ; thcfc divide into three fniallerfoot-ttalks, each of which arc again divided into three, and thefe have each three lobes , fo that each leaf is compofcd of 27 lobes or fmal- ler leaves. The flowers grow in ramous fpikes, and arc of a pure white: they are borne upon a dcndcr, jointed, and furrowed llcm; appear inMay; and are fucceedcdby black, fhining, pulpy berries, about the li^c of peas, whicii ripen in the autumn. This plant is a powerful repellent, and the root has been ufed internally in fomc nervous cafes, but muft be adminiftercd with caution. The berries arc highly poifonous. It isfaid toads re- fort to this plant, on account of its fetid fmell. Sheep and goats cat it ; cows, horfcs, and fwinc refufe it. 2. The alba, or Amcricanhcrb-chriftophcr, isa native of North America. The leaves of this fpccics arc fomc- what like the former, but not fo deeply indented in iho edges. The flowcrsgrowin a morecompael fpike, and the berries arc very white and tranfparent when ripe ; the roots arc compofcd of thick knobs. This fpecics has been ufed as an emetic, and fometimes called ipe- cacoaiiha. 3. The raceinofa, or American black or wild inakcroot, is likewife a native of Nonh-Amtrica. It has large compound Icavcs.riling immediately from the root, and branched after the fame manner as the firft which grow more than two feet high. The flowcr- ftcm rifcs to the height of four or five feet; and carries along fpike of white ilowers refiedrled atthetop. Thcfc appear in June or the beginning of July, but the feeds do not come to maturity in Britain. The root of this plant is greatly ufed by phylicians in this country, in many diforders ; and is fuppofcd to be an antidote a- gainft poifon, or the biting of a raitle-fuakc. 4. The cimicifuga, is A native of Siberia ; the leaves rcfemblc thcfc of the feathered columbine ;theftalks ri£e little more than a foot high, fupporting particles of white flowers, which appear in ftlay. This fpecies is rare in Britain. N 2 Culture. AftT, ACT [ 100 1 ACT Culture. Tlic (irfl fpccics hath .1 perennial root, but the ihlks aumially decay.

This fpecics delights in a light r.ioill foil, and lliady liiuation — The third is nfually propagated by feeds feiii annually from North America : it thrives in the fame kind of foil as thefor- mer ; and is very hardy, requiring no other culture than the common tlowering-lhrubs. 'I'he plants fliould not be often removed for that will prevent their How- ering llrong The fourth requires a moill; loamy foil, and ihady iltuation. It may be propagated in the fame manner as the others. ACTytON, in fabulous hiflory, the fon of Arifl^tus and Autonoe ; a great hunter.

The body is oblong and fmootli, attaching itfclf lirmly by its balls to rocks or other folid fubrtances, having a dilatable apex hooked within. The mouth is furniihed with crooked teeth, thcroftrum cylindrical and radiated. There are five fpccies, fomc of which make a beautiful appearance, and arc called Annual Flo'Jj:;rs, S;a Aueji.-oniis, and Urti'.a Miiiiiia. See A n t m a i. Fionvir.

The forniirtiiies ufed by the Ro- mans, injudicial adliuns, were thefc : If the ditference tailed to be made up by friends, the injured perfons proceeded //; jus rcuvt vocan, to fummon the offending party to the court, who was obliged to go and give bond tor his appearance. The oitcnding party might be fumnioned into courc viviivcce, by the plaintilfhimfclf meeting the defen- dant, declaring his intention to him, and commanding him to go before the magifirate and make his defence. If he would not go willingly, he might drag and force him along, unlets he gave fecurity for his appearance on Ibme appointed day. If he failed to appear on the day agreed on, then the plaintiri', whcnfoeverhe met him, might take him along with him by force, calling any by-ltandtrs to bear W'itnefs, by alkingthem vi/rii: antejlari ; the by-flanders upon this turned ihcir ear to- wards him in token of their coufcnt : To this Horace alludes in his Sat. againil the impertinent. Lib. I . Sat. 9. See this further explained under the article An- TESTARI. Bath parties being met before the pr«tor, or other fupreme magifirate prcfidingin the court, (he plaintift propoft. d the attion to the defendant ; in which he de- Jigncd to profeciite him. This they termed cdcre ac- tionem ; and was corrmonly performed by W'riting it in a tablet, andolieringit to the defendant, that he might fee whether he had better Hand the fuit or com- pound. In the next place came the poptihtio a{lionis , or the plantiti's petition to the prsetor, for leave to profecutc the defendant in fuch an adion. The petition was granted by writing at the bottom of it nfiionem do, or refufcd by writing in the fame manner aHi^netu noii do. The petition being granted, the ^\z.Vi\\?i vadahattir reum, i. e. obliged him to give fureties for his appear- ance on fuch a day in the court ; and this w-as all that was done in public, before the day fixed upon for the trial. In the mean time, the difference was often made up, either tranfaBioni:, by lettingthecaufcfall as dubious ; or paCiiane, by conipofition for damages amongll friends. On the day appointed for hearing, the prastor or- dered the feveral bills to be read, and the parties fum- moned by an accmifiis, or beadle. See Accensi. Upon the non-appearance of cither pai.y, the de- faulter lofl his caufe ; — if they both appeared, they were faid fi: f\ stir's ; and the the plaiiuifF proceeded liietn fiv! alliontiiilntcitdvre, i. e. to prefer his fuit, which was done in a fet form of words, varying accor- ding to the difference of the aftions. After this the plaintiff delired judgment oftlie praetor, that is, robe allowed a judix or arbiter, or elfe the rccuperaton:! or centumviri. Thefe he requeflcd for the hearing and deciding the bufinefs ; but none of them could be de- fired but by the confent of both parties. The pr.'sior having aHigned them their judges, de- fined and determined the number of witnelfes to bead- milted, to hinder the protracling of the fuit ; and then the parties proceeded to give their caution, that the ACT [ loi 1 A C 1' ilicjuJKiiicnr, whaicvcrkwas, illo^ll.lftanJan•.ibcpcr- ' fi)i-iiicd onboili fides, 'riicjadgcs took a t'olrninuach to be imparlial; and the parties took l\\cj:'r.i»u-».'.-iiu calumiiia. Then the ti ial W-^iw with the afilftancc of witriellcs, writings, 8:c. which was called djccftaih Action, in a general ftnfc, iinplics nearly the fume thing with Act. — Grammarians, however, ob- fcrvc fomc dillintlion between afl/o/zand ail ,• ilic for- mer being generally reftrit'ted to the common or ordi- nary trsnfactions, whereas the latter is ufed tocxprcfs thofc which are remarkable. Thus, wc fay it is a good eSlion to comfort the unhappy ; it is a generous ah to deprive ourfclves of what is nccelury for tlieir fake. The wife man propofcs to hinifelf an honcfl end in all his ti{fio)ts ; a prince ought to mark every day of his life with fomc a{l of greatnefs. The a!)b^ Cirard makes a further diflindion between the words action and aff. The former, according to him, has more relation to the power that afts than the latter ; whereas the latter has more relation to the eifeCt produced than the former : and hencethe one isproperly theattributeof the other. Thus wc may properly fay, " Be Aire to prcfervc a prefcnce of mind in all your adlions ;and take care that they all be acts of equity." Action, in mechanics, implies cither the effort which a body or power maJ^es again fl another body or power, or the effeifl itfelf of that.etfort. Asitisnccelfiry in works of this kind to have a par- ticular regard to the common language of mechanics and philofophcrs, vve have given this double detiiiition : but the proper fignification of the term is the motion which a body really produces, or tends to produce, in another ; that is, fuch is the motion it would have pro- duced, had nothing hindered its cffedl. All power is nothing more than a body actually in motion, or which tends to move itfelf ; that is, a body which would move itfelf if nothing oj'pofcd it. The adion therefore of a body is rendered evident to us by its motion only ; and confequently we muft not fix any other idea to the word adion, than that of adlual mo- tion, or a fiuiple tendency to motion. The famous que- lliou relating to -ois viva, and vii mortua, owes, in all probability, its e.\iftence to an inadequate idea of the word action ; forbad Leibnitz and hisfoUowersobfer- ved, that the only precife and diiUniit idea we can give to the word force or aition, reduces it to its effir .51, that is, to the motion it adlually produces or tends to pro- duce, they would never have made that curious dif- tinclion. (lliaiitity of Acriox, a name given by ]\J. de M.ui- periuis, in the Memoirs of the Pariiian Acailemy of Sciences for i 744, and thofc of Berlin for i 746, to the product of the mafs of a body by the fpace w liich it runs through, and by its celerity. He lays it down as a general law, "that, in thechsnges made in the "rtatcof ahody, the quantity of adtion neceflary to pro- " ducc fuch a change, is the lealt pofTiblc." This prin- ciple he applies 10 the invcfligation of ilie laws of rc- lrai5lion,of equilibrium, &c. and even to the ways of aiJifng employed by the Supreme Being. In tliis man- ner M. de Maupertuis attempts to cnnccl the meta- phylics of ilnal caufcs with the fundamcndal truths of mechanics, to Ihow the dependence of the coliiiion of both ehftic and hard bodies upon one and the fame law, which before had always been rc/errtil to I'rptr.-.tc laws ; and 10 reduce the laws of motion, aiul thofc of equilibrium, to one and the fame principle.

Action, in painting and fculpture, is the attitude or pofition of the feveral parts of the face, body, and limbs of fuch figures as arc reprcfcnied, and whereby they fccm to be really aftuated by paliions. Thus wc fay, the aftion of fuch a figure hncly exprelTcs the paflions with which it is agitated : wc alio ufc th« fame cxprcliion with regard to animals. Action, in phyliology, is applied to the function? of the body, whether vital, animal, or natural. The c/w/ functions, or actions, are thofc which are abfo'utely nccelTary to life, and without which there is no life, as the aftion of the heart, lungs, and arteries. On the action aHd reaction of the folids and iluids o.i each other, depend the vital functions. The pulfc and rcfpiration are the external llgnsof life. Vital difeafcJ are all thofc which hinder the influx of the venous blood into the cavities of the heart, and the expidhon of the arterial blood tVom the fame. — The /w/.vr.j/ func- tions are thofe which are inllrumental in repairing the feveral lolfcs which the body fuflains ; for lifeisdcf- truftive of itfelf, its very otRces occafioning a perpe- tual wafle. Thcmanducation of food, the deglutition and digeftion thereof, alio the fcparation and didribu- lion of the chyle and exerementitous parts, &c. arc under the head of natural functions, as by thcfe oura- liment is converted into our nature. They arc nccclfa- rytothe continuance of our bodies. — Tlieanir/ia! func- tions arc thofc which we perform at will, as mufcular motion, and all the voluntary actions of the body, they are thofe which conftitutc the fenfes of touch, taflc, finell, fight, hearing ; perception, rcafoaintr, imagina- tion, memory, judgment, atFcftionsof themind.\S'i;h- out any, or all oftheui, a man may live, but not fa com- fortably as with them. Action, in commerce, is a term ufed abroad for a certain part or lliare of a public company's capital Aock. Thus if a conipany has 400.000 livres capital Hock, this may be divided into 4C0 actions, caeli con- lifting of 1000 livres. Hence a man is f.iid to have two, four, &c. actions, according as he has the property of two, four, cic. 1000 livres capital Itock. The trans- ferring of actions abroad is performed much in the fame manner as ftocks are in England. See .Stock?:.

ACTIONS, aiiioiu' merchants, fomctimes fignify moveable ctfeds ; and we fay the merchant's creditors have feizcd on all his aflions, when we mean that they have taken poirdllon of all his active debts. ACTIVE, denotes fomething that communicates aftion or motion to anotlicr ; in which acceptation it Hands oppofcd to padive. Active, in grammar, is applied to fiich words as . exprefsaflion;andis thcrcforeoppofed topaffivc. The adive performs the adion, as the pallivc receives it.

Neuter verbs alfo denote an adlion, but are diftingnidicd from adivc verbs, in that ihey cannot have a noun following them : fuch arc To Jlcep, to go, i7c. — Some grammarians, however, make three kiiidsof active verbs: xXxctiaiifdOive ,\\\\cxc the aftion pail'cs into a fubjcc^ ditfc-rent from the agent : rcficOcd, where the aflion returns upon the agent ; tmA reciprocal, where the action turns mutually upon the two agents who produced it.

ACTON, a town near London, where is a well that affords a purging water, w-hich is noted for the pun- gency of its fait. This water is whitilh, to the tafte it is fweetilh, with a mixture of the fame bitter which is in the Epfom water. The fait of this water is not quite fo (oft as that of Epfom ; and is more calcareous than 02 ] ACT it, being more of the nature of the fait of lime : for a quantity of the Adon water being boiled high, on be- ^ ing mixed with a foluiion of fublimatc in pure water, threw down a yellow fcdiment. The fait of the Adon water is more nitrous than that of Epfom ; it Itrikcs a deep red, or purple, with the tiiidure of logwood in brandy, as is ufual with nitrous falts ; it does not pre- cipitate lilver out of the fpirit of nitre, as common fait docs: I ; lb of this water yields 48 grains of fait. ACTOR, in general, (ignifies a perfon who ads or performs fomething. Actor, among Civilians, the prodor or advocate in civil courts or caufcs : as, ^iVrt/r ecclef^ has been fomelimes ufed for the advocate of the church ; a{hr domiiiicus for the lord's attorney ; a{lor villcc, the llew- ard or head baililFof a village. Actor, in the drama, is a perfon who reprefcnts fome part or charadcr upon the theatre. The drama coniilkd originally of nothing more thanafimple cho- rus, who fung hymns in honour of Bacchus ; fo that the primitive adors were only fingers and mulicians. Thefpis was the firft that, in order to cafe this un- formed chorus, introduced a declaimer, who repeated fome heroic or comic adventure, ^ii^fcliylus, finding a linglc perfon tirefome, attempted to introduce a fe- cond, and changed the ancient recitals into dialogues. Mc alfo drclled liis adors in a more majcftic manner, and introduced the cothurnus or buikm. Sophoclci added a third, inordcrtoreprefentthe variousincidcnts in a more natural manner: and here the Greeks Hopped, at leall we do not lind in any of their tragedies above three perfons in the fame fccne. Perhaps they lookcu upon it as a rule of the dramatis poem, never to admit more tlian three fpeakers at a time on the flage ; a rule which Horace has exprelfed in the following verfe : Nee quarta loqiii perfona lahoret. This, however, docs not prevent their increafing the number of adors in comedy. Before the opening of a play, they named their adors in full theatre, together with the parts they were to perform. The ancient adors were mafked, and obliged to raife their voice extremely, in order to make themfelves heard by the innumerable crowd of people who filled the amphithe- atres: thcywere accompanied with a player on thertute, who played a prelude, gave them the tone, and play- ed while they declaimed. Horace fpeaks of a kind of fecondary adors, in his time, whofe bulinefs was to imitate the firft ; and IclTcn themfelves, to become bet- ter foils to their principals. The moderns have introduced an infinite number of adors upon tlie flage. This heightens the trouble and diftrefs that lliould reign there, and makes a divcrfity, in which the fpedator is Ak'c to be interefled. Adors were highly honoured at Alliens. At Rome they were defpifed, and not only deiiyed all rank among the citizens, but even when any citizen appeared upon the flage he was expelled his tribe and deprived of the right of fufFrage by cenfors. Cicero, indeed, efteems the talents of Rofcius : but he values Ivij virtues flill more ; virtues which diftinguiflied him fo remarkably above all others of his profelfion, that they feemed to have excluded him from the theatre. The French have, in this refped, adopted the ideas of the Romans; and the Englilh thofe of the Greeks. Actor, the name of fevcral perfons in fabulous hi- Hory Aflor. ACT [1 ftcry.

ACTRESS, in a general feafe, a female who acis or performs fomething. Actress, in the drama, a female performer. %\'o- men aCtors were unknown to the ancients, among whom men always performed the female charader ; and hence one rea(bn for the ufc of malks among them. Aetreflesarc faid not to have been introduced on the Englilh llage till after the rcllor.uion of king Charles II. who has be-n charged with contributing to the corruption of manners by importing this ufage from abroad. But this can be but partly true : the queen of James I. afted a part in a palloral ; and I'rynn, in his Hillriomaftix, fpeaks of women aClors in his time as whores ; which was one oceafion of the fcverc profecution brought againll him for that book. Thcreare fome very agreeable and beautiful talents, of which the poircflion commands a certain fort of ad- miration ; but of which the excrcife for the fake of gain is confidered, whether from reafon or prejudice, as a fort of public proditution. The pecuniary recom- pencc, therefore, of thofe who excrcife them in this manner, mull be fufRcient, not only to pay for the time, labour, and expence of acquiring the talents, but for the difcredit which attends the employment of them as the means of fubfiftence. The exorbitant re- wardsof players, opera-fingers, opera-dancers, &c. arc founded upon thofe two principles ; the rarity and beauty of the talents, and the difcredit of employing them ill this manner. It feems abfurd at lirll light that wc fliould defpife their perfons, and yet reward their talents with the moll profufe liberality. While We do the one, however, wc muft of neccihiy do the otlicr. Should the public opinion or prejudice ever al- ter with regard to fuch occupations, their pecuniary reeompence would quickly diminilh. More people would apply to them, and the competition would quick- ly reduce the price of their labour. Such talents, though far from being common, are by no means fo rare as isimagincd. Many people polfcfs them in great perfeftion, who difdaiu to make this ufc of them; and many more are capableof acquiring them, i^any thing could be made honourably by them. ACTUAL, fomething that is real and effedlive, or that cxills truly and abfolutely. Thus philofophcrsufc the terms aSlual heat, adtiat cold, &c. in oppolltion to virtual or potential. Hence, among phylicians, a red-hot iron, or fire, is called an actual cautery ; in di- ilintlion from cauteries, or caullics, that have the power of producing the fame tft'ecl upon the animal iblids as aflual fire, and are called pol.ntiiil caute- ries.

ACULEATE, or AcuLEATi, a term applied to any plant or animal armed with prickles. • ACULEI, the prickles of animals or of plants.

After having devoted fome years to ftudy, he went to America, where he af- fifted in making converts in Chili and Peru. In 1640, he returned to Spain, and gave the king an account how far he had fucceedcd in the commilHun he had re- ceived to make difcoveries on the river of the Amazons; and tlic year following he publiihed a dcfcripiion of this river, at Madrid, .\cuna was lent to Rome, ?s procurator of his province.

ADAM, the fird of the human race, was formed by the Almighty on the lixth day ofthe creation. His body was made of the dud ofthe earth ; after which, God animated or gave it life, and Adam then became arationalcreaturc. — Hisheavenly Parent did not leave hisoliipringin adeditutc date to fliift forhimfelf : but planted a garden, in which he caufed to grow not on- ly every tree that was proper for producing food, but likcwife fuch as were agreeable to the eye, or merely ornamental. In this garden were alfemblcd all the brute creation ; and, by their Maker, caufed to pals before Adam, whogaveallof them names, which were judged proper by the Deity himfelf. — In this review, Adam found none for a companion to himfelf. This folitary date was feen by the Deity to be attended with fome degree of unhappiuefs ; and therefore he threw Adam into a deep llccp, in which condition he took a rib from his lide, aid healing up the wound formed a woman of the rib he had taken out. On Adam's a- waking, the woman was brought tohim ; and he im- mediately knev^ her to be one of his own fpecics, call- ed her his bone and his tlelTi, giving lier the name of •w'jmr.ii becaufe Ihe was taken out of man. The fird pair being tluis created, God gave them authority over the inferior creation, commanding them to fubdue rffe earth, alfo to incrcafe and multiply and (ill it. They were informed of the proper food for the beads and for them ; the grafs, or green herbs, being appointed for beads ; and fruits or feeds, for man. Their proper employment alfo was afligiied them ; namely, to drcfs thi garden, and to keep it. T hough Atiainv.'a'sthushighly favoured andindruc- tcd ADA [ I AJam. ted b/ his Maker, there nas a liiiglc tree, wliicli grew ' •■'-—^ in the middle of the garden, of the fruit of which they were not allowed to cat ; being told, that they IhoulJ furely die in the day they eat of it. This tree was named, the Tree oj the Knowledge of CooJ and Evil. This prohibition, however, they foon broke tlirongh. The woman having entered into cor.vtrfation with the Serpent, was by him ptrfuadcd, tjiat by eating of the tree (lie ihouUl become as wife as God himftlf ; and ac- cordingly, being invited by thcbcaMty of the fruit, and its defirable property of imparting wifdom, Ihe plucked and eat ; giving her hufband of it at the fame time, who did likewife eat. Before this tranfgreflion of the divine command, A- dam and his wife had no occafion for clothes, neither had they any fenfe of (hamc ; but immediately on eat- ing the forbidden fruit, they were alhamed of being naked, and made aprons of tig-lcaves for thcmftlves. On hearing the voice of God in the garden, they were terrified, and hid themfclvcs : but being qucltioiicd by the Deity, they confelfed what they had done, and re- ceived fcntence accordingly ; the man being condemn- ed to labour ; the woman to fubjcdion to her luif- band, and to pain in childbearing. They were now driven out of the garden, and their acccfs to it pre- vented by a terrible apparition. They had clothes given them by the Deity made of the Ikins of bcalls. In this Hate Adam had feveral children ; the names of only three of whom we are acquainted with, viz. Cain, Abel, and Scth. He died at the age of 9 jo years. Thcfe are all the particulars concerning Adam's life, that we havcon divineauihority : but a vaft multitude of othersareadded by thejews, Mahometans, andothers; all of which niuft be at befl conjci.1nral ; molt of them, indeed, appear downright falfehoods or abfurditics. The curiofity of our readers, it is prefumcd, will be fuf- ficiently gratified by the few that are here fubjoincd. According to the Talmudills, when Adam was cre- ated, his body was of immcufe magnitude. When he fmncd, his flature was reduced loan hundred ells, ac- cording to fome; to nine hundred cubits, according toothers ; who think this was done at the requeft of the angels, who were afraid of fo gigantic a creature. In the idand of Ceylon is a mountain called the Veak or mountain of Adam, from its being according to the tradition of the country, the relidcucc of our firfl pa- rent. Here the print of his fooiftcps, above two palms in length, arc llill pointed out. Many reveries have been formed concerning the perfonal beauty of Adam. That he was a handl'ome well-lhapcd man is probable ; but fome writers, not content with this, affirm, that God, iniendiiig to create man, clothed Himfclf with a pcrfedly beautiful human body, making this liis model in the formation of the body of Adam. Nor has the imagination been If fs indulged con- cerning the formation of the human Ipecies male iiul female. — It would be endlefs to recount all the vhim- fics that have been wrote on this fubjcifl ; but as Mad.

The body or Adam was purer and r.iore tranfparenithancryiUl, and vaRly Hcet ; through this body were fcen veilels and rivulets of light, which penetrated from the Inward ti> the ounvard parts, through all his pares. In fome velfels ran fluids of all kinds and colours, vaftly bright, and quite diaphanous. The nioft raviihing harmoi;/ arofc from every motion ; and nothingrelilled,or coulJ annoy, him. His flature was taller than the prefent race of men : his hair was Ihort, curled, and of a colour inclining to black ; his upper lip covered with ihort hair : and initead of the beftial parts which modefty will not allow us to name, he was falliioned as our bo- dies will be in the life eternal, which I know not whe- ther 1 dare reveal. In that region his nofe was form- ed af'ter the manner of i face, which difiufed the mofl deliciousfra2;rancyandpcrfumes;whencca!fomeu were toillue.all whole principles were inhercntin him ; there being in his belly a veliel, where little eggs were form- ed ; and a fecoud veliel rilled with a fluid, « hich impreg- nated thofc eggs : and when nun heated himfclf in the love of God, the dclire he had that other creatures Ihould exifl belides himfelf, to praife «nd love God, caufcd the fluid abovementioned (by meansof the nrc of the love of God) to drop on one or more o( thefc eggs, with ine.xpreliible delight ; which being thus im- pregnated, ilfacd, fome time at'ter, out of man, by tiiis canal |-, in the fliape of an egg, whence a perfect man t '■ '• '*>< was hatched by infenfible degrees.

Several Chriitians fcem to be littlebehindthefe Jews in the degree ofknoN\ ledge they afcribc to Adam ; nothing being hid from him, ac- cording to them, except contingent events relating to fiuiirity. One writer indeed (I'incdo) excepts politics ; but a Carthiifian friar, having cxhaufled, in favour of Arillotle, every image and comparifon he could think of, at lall alfcrts that Arillotle's knowledge was as ex- tonlive as that of Adavi. — In confequencc of this fiir- priling knowledge with which Adam was endued, he is fiippoicd to hive been a confiderable author- The Jews pretend that he wrote a book on the creation, and an- other on the Deity. Some rabbles afcribe the 9a'' pfalm to Adam ; and in fome manufcripts the Chaldee title of this pialra exprcfsly declares that this is the fong of praife which tlicfirlt man repeated for the fabbath-day. Various conjecftures have been formed concerning the place where man was firft created, and where the garden of Eden was fituuted : but none of thefc have any folid foundation. The Jews tell us, that Eden was fcparatcd from the refl of the world by the ocean ; and that Adam, being banifhed therefrom, walked acrofs the fea, which he found every way fordable, by rea- fonof his enormous ftature*. The Arabians imagined ■ paradife to have been in the air ; and that our firll: pa- rents were thrown down from it on their tranfgref- fion, as Vulcan is faid to have been thrown down headlong from heaven by Jupiter. Strangeftoriesarc told concerning Adam'schildren. , That he had none in tlie (late of innocence, is certain . from fcriptnre; but that his marriage with Eve was not confummated till after the fall, cannot be proved from tiience. Some imagine, that for many years after the fall, Adam denied himfelf die connubial joys by way of penance; others, that he cohabited with ano- ther woman, whofe name wasLii.iTH. The Ma- hometans tell us, that our firfl parents having been thrown headlong from the celeflial paradife, Adam fell upon the iiie of Serendib,- or Ceylon, in the Eafl-In- dies; and Eve on lodda, a port of the Red Sea, not far from Mecca. After a feparation of upwards of 200 years, they met in Ceylon, where they multiplied : according to fome Eve had twenty, accgrding to others only eight, deliveries ; bringing forth at each time twins, a male and fcm.ile, who afterwards married. The Rabbins imagine that Eve bruuglu forth Cain and Abel at a birth ; that Adam wept for Abel an hun- dred years in the valley of tears near Hebron, dur- ing which time he did not cohabit with his wife ; and that this feparation would probably have continued longer, had it not been forbid by the angel Gabriel. The inhabitanis of Ceylon affirm, that the fait lake on the mountain of Colembo confifls wholly of the tears which Eve for one hundred years together Ihed becaufe of Abel's death. Some of the Arabians tell ns, that Adam was buri- ed near Mecca on Mount Abukobcis : others, that No- ah, having laid his body in the ark, caufed it to be carried after the deluge to Jerufalem by Mclchifcdek the fon of Shcm : of this opinion are the eaftern Chriftians ; but the Perfians affirm that he was interred iii the iHc of Serendib, where his corps was guarded by lions at the time tlie giants, warred upon one another, Adam St Jcroni imagined that Adam was buried at Hebron ; | others, on Mount Calvary. Some are of opinioH that Adamitii. he died on tlic very fpot where Jerufaleni was after- ^~^ wards built ; and was buried on the place where Chrifl fuffered, that fo his bones might be fprinkled with the Saviour's blood ! ! ! Adam (Mclchior) lived in the 17"' century. He was born in the territory of Groikaw in Silclia, and eilucated in the college of Brieg, where the dukes of that name, to the utmofl of their power, encouraged learning and the reformed religion as profelfed by Cal- vin. Here he became a firm Proiellant ; and was en- abled to purfue his lludiesby the liberality of a perfon of quality, who had left feveral exhibitions for young Ihidcnts. He was appointed rector of a college at Heidelberg, where he publilhed his firfl volume of il- lullrious men in the year 1615, This volume, which coniillcd of philofopliers, poets, writers on polite li- terature, and hiflorians, &c. was followed by three o- tliers ; that W'hich treated of divines was printed in 1619 ; thatof the lawyers came next ; and, finally, that of the phylicians : the twolallwere publilhed in 1620. All the learned men, whofe lives are contained in thefc four volumes, lived in the 16"', or beginningof theiy"" century, and are cither Germans or Flemings; but he publilhed in 1618 the lives of twenty divines of other countries in a feparate volume. All his divines are Pro- teflants. The Lutherans were not pleafed with him> for they thought him partial ; nor will they allow his work to be a proper ftandard whereby to judge of the learning of Germany.

This ADA [ »o7 ] A D A Adamui This obfcure and ridiculous fcc'l did not at firfl laft I long ; but it was revived, with a4!ditionalal»furdilics, in Adamfnn. the twelfth century, by one Tandainus,(incc known by ' the name of Tanchelin, who propagated his errors at Antwerp, in the reign of the emperor Henry V. He maintained, that there ought to be no diftinctiou be- tween priefts and laymen, and that fornication and a- dultery were meritorious ac'tions. Tanchtlin had a great number of followers, and was conltaiuly attend- ed by 3000 of thele profligates in arms. His feft did not, however, continue long after his death : but ano- ther appeared under the name of Turlupins, in Savoy and Dauphiny, where they committed the mod bru- tal aflioiis in open day. About the beginning of the fifteenth century, one Picard, a native of l-'landers,; fpread thefe errors in Germany and Bohemia, particularly in the army of the famous Zifca,notwithfiandingthefeveredifcipline he maintained.

This feft found alfo fome partizans in Poland, Holland, and England : they afleniblcd ia the night ; and it is afferted, that one of the funda- mental maxims of their fociety was contained in the following verfc : Jura, perjura^ficrttum prodcre noli.

ADAMSON (Patrick), a Scottifli prelate, archbi- fliop of S[ Andrews. He was born in the year i J43 in the townof Perth, where he received the rudiments of his education ; and afterwards lludied philofophy, and took his degree of mailer of arts at the univerfity of St Andrews. In the year is66, he fet out for Paris, as tutor toayoung gentleman. In the month of June of the fame year, Mary queen of Scots being delivered of a foil, afterwards James VI. of Scotland and Kirft of England, Mr Adamfon wrotea Latin poem on the occafion. This proof of his loyalty involved himinfomediificuhics, havingbccn conlined in France for (ix months ; nor would he have eahly gut oif, had not Queen Mary, and I'omc of the principal nobility, intcrcftcd ihcmfclvcs in his behalf. As'fooii as he re- covered his liberty, he retired with his pupil to Bour- ges. He wasin this city during the nialTacre at Paris; and tlic fame pcrfccuting f))irit prevailiutf amimg the catholics at Bourges«a»at the metropolis, he lived concealed for fevcn months in a public houfe, the ma- flerof which, upwardsof 70 yearsof age, was thrown from the top thereof, and had bis brjins Jaflud out, for his charity to heretics. VVhilll Mr Adamfon lay thus in hisfepulchrc, as he called it, lie wrote his La- tin poetical vcrfion of the Book of Job, and his Tra- gedy of Herod in the fame language. In the year I )7?> he returned to Scotland ; and, having entered intoholyordcrs, became mini fler of I'aillcy. In the year r J7J, he was appointed one of^he commillioners, by the general atTcmbly, to fettle the jurifdiiftion and Po- licy of the church ; and the following year he was lu- AJm. nied, with Mr. David Lindfay, to report their proceed- * — ings to the earl of Mortoun, then regent. About tliis time the earl made hira one of his chaplains ; and on the death of bifhop Douglas, promoted him to the archicpifcopal fee of St Andrew's, a dignity which brought upon him great trouble and uncafmcfs : for novr the clamour of the prefbyterian party rofe very high a- gainilhim, and many inconlillcni abfurd ftorics were propagated concerning him. Soon after his promo- tion, he publilhed his catechifm in Latin verfe, a work highly approved even by his ecemics ; but nr- verthelcis, they Hill continued topcrfecute him with great violence. In i)78, he fubinitted hinilelf to the general aflembly, fthich procured him peace but fora very little time ; for, the year following, they brought frelh accufations againll him. In the year 1 5S2, being attacked with a grievous difeafe, in which the phyficians could give him no relief, he happened to take a limple medicine from an old woman, which ■ did him fervicc. The woman whofe name was Alifiajelty, with great reputation, which drew upon hiin frelh calumny and perfecution. The king, however, uaslb well pleafcd with him, that he fent him ambartader toQiiecn Eii- fabeth, at whofe court he refided for fome years. His conduct, duringhis em bally, has been variouily report- ed by different authors. Two things he principally laboured, nc. the recommending the king his mailer to the nobility and gentry of England, and the pro- curing fome fupport for the epifcopal party in Scotland. By his eloquent preaching, lie drew after him fuch crouds of people, and raifed in their minds fuch a high idcaof theyoungking hismafter, that queen Elil'abcth forbad him to enter the pulpit during his ftay in her dominions. In 1584, he was recalled, and fat in the' parliament held in Auguft at Edinburgh. ThePrcfcy- terian party was flill very violent againfl the arclibi- fliop. A provincial (j-nod was held at St Andrew's in April 1586 ; the Archbifliop was here accuftd and excommunicated : he appealed to the king and lli« flates, but this availed him little : for the mob being excited againfl him, he durll fcarce appear in public. At the next general allcmbly, a paper being pro- duced containing the archbilhop's fubiiiilnon, he was abfclvcd from the cxcomniunicalioti. In 1588, frelh accufations were broticrht againfl him.

AD.ANSONIA, ETHioriAS Sour-gourd, Mon- KiES-BREAD, or Akrican' Ca l Aa AS h-tree, a genus of the nionodelphia order, belonging to the polyaudria clafs of plants ; the characters of whiehare : The calyx is a perianthium one Icav'd, iialf live-cleft, ciip-lorm, (the divilions revolutc), deciduous: The corolla con- lillsof five pciali, mundidi nerved, rcvolute, growing reciprocally svitli the claws and Itamina : \.\\c Jiamiiia have numerous filaments, coalefccd beneath into a tube, and crowning it, expanding horizontally thcanthera: .kidney-form, incumbent : The piflillum has an egged germ ; the llylus very long, tubular, varioufly intoned; the iligmata numerous ( i o) prifmatic, villous, ray-cx- pandcd : '^\\.t pincnrptinn is an oval capfule, woody, not gaping, ren-celled, with farinaceous pulp, the par- titions membranous : 'YXvi feeds are numerous., kidney- ihapcd, ratherbony, and involvedina friable pulp. There is at prefent butone known fpecicsbelonging to this genus, the Baobab, which is perhaps the lar- gell produdion of the whole vegetable kingdom. It is a native of Africa. The trunk is not above laor 15 feet high, but from 65 to 78 feet round. The lovvcll branches extend al- raoR horizontally ; and as they are about 60 feet in length, their own weight bends their extremities to the ground, and thus form an hcmifpherical mafsof ver- «lure of abinit izoor i3ofect diameter. The roots txtcnd as far as the branches: that in the middle forms a pivot, which penetrates a great way into the earth ; tlie reft fprcad near the furiace. The dowers are in [iroportion to the fizc oi' the tree : and arc followed by an oblong fruit, pointed at both ends, about 10 inches loiig, five or fix broad, and covered with a kind of grccniih down, under which is a ligneous rind, hard and alinoft black, marked with rays which divide it Icngtliwifc into fides. The fruit hangs to the tree by a pedicle tw^o feet long and .in inch diameter. It con- tains a whiliih fpongy juicy fnbflancc ; with feeds of a brown colour, and ihaped like a kidney bean. The bark of this tree is nearly an inch thick, of an' alh- coloured grey, greafy to the touch, bright and very fniooth : the outfideis covered with a kindofvarnilli; and the infide is green, fpccklcd with red. The wood is white, and very foft ; the firfl flioots of the ear are creen and downy. The leaves of the young plants are entire, of aaob- long form, about four or five inches long, and almofl three broad towards the top, having fc veral veins run- ning from the middle rib ; they arc of a lucid green Adanfonai. colour. As the plants advance in height, the leaves "— — ^/ ' alter, and arc divided into three parts, and afterwards into five lobes, which fprcad out in the ihapc of an hand. The tree llieds its leaves in November, and new ones begin to appear in |unc. Its ilowcrs in July, and the fruits ripens in Ottobtr and iS'ovember. it is very common in Senegal and the Cape de Verd idands : and is found 100 leagues up thecountry at Gulam, and upon the fea-coili as far as Sicrra-ltona. The age of this tree is perhaps no lefs remarkable than iis enormous lize. Mr Adanfon relates, that in a botanical cxcurllon to the Aiagdalenc idands, in the neighbourhood of Gorce, hcdifcovercd fonie calabalh- trecs from five to lix feet diameter, on the bark of which were engraved or cut to a confiderable depth a number of European names. Two of thefe names, wiiich he was at the trouble to repair, were dated one the 14th, the other the 15th century. The letters were about lix inches long, but in breadth they occu- pied a very fmallpart only of the circumference of the trunk : from whence he concluded they had not bcca cut when thefe trees were young. Thefe infcripiions, however, he thinksfufficient to determine pretty nearly theage whichthefccalaballi-trcesmay attain ; for even fuppofmg that thofe in quciUon were cut in their early years, and that trees grew to the diameter of lix fecc in tv.o centuries, as the engraved letters evince, how many centuries mufl be reiiuifitc to give them a dia- meter of 25 feet which perhaps is not the laft term of their growth ! The infcribed trees mentioned by this ingenious Frenchman had been fcen in tJ5J, almolt two centuries before, by Thevet, who mentions them in the relation of his voyage to Terra Antardica or Auflralis. Adanfon favv them in i 749. The virtues and uf€s of this tree and its fruit arc various. The negroes of Senegal dry the bark and leaves in the Ihadcd air ; and then reduce them to powder,' which is of a pretty good green colour. This powder they preferve in bags of linen or cot- ton, and call it idlo. They ufe it every day, putting two or three pinches of it into a mcfs, whatever it happens to be, as we do pepper and fait : but their view is, not to give a rclifli to their food, but to pre- ferve a perpetual and plentiful perfpiration, and to at- temper the too great heat of the blood ; purpofes which it certainly anfwers, as feveral Europeans have proved by repeated experiments, prcfervingthemfelvcs from the epidemic fever, which, in that country, de- flroys Europeans like the plague, and generally rages during th.e months of September and Odtober, when, the rains having fuddenly ceafed, the fun exhales the water left by them upon the ground, and fills the air with a noxious vapour. M. Adanfon, in that critical feafon, made alight ptifan of the leaves of the baobab, which lie had gathered in the Augull of the preceding year, and haddriedin the iliade ; and drank conltantly about a pint of it every morning, cither before or af- ter breakfafl, and the fame quantity of it every even- ing after the heat of the fun began to abate ; he alfo fometimcs took the fame quantity in the middle of the day, but this was only when lie felt fome fymptomsof an approaching fever. By this precaution he prefer- ved himfelf,during the five years he refided at Senegal, from the diarrhcea and fever, which are fo fatal there and, ADA [ 109 ] ADA (Jaiifonia and whicli are, however, the only dangerous difcafcs I of the place ; and other officers flittered very ftvercly, Adar. only one excepted, upon whom M. Adaiifon pr'^v^ilcd " to life this remedy, which for its iimplicity was dcf]'i- fed by the rcil. This ptiL-- alone alfo prevents that heat of urine which is common in thefe parts, from the month of July to November, provided the pcrfon ab- ftains from wine. The fruit is not lefs ufefiil than the leaves and the bark. The pulp that envelopes the feeds has an agree- able acid taflc, and is ea;cn for plcafure : it is alfo dried and powdered, and thus ufed medicinally in pclli- lential fevers, the dyfcntery, and bloody iiux ; tlic dofe is a drachm, pallid through a tine lieve, taken either in common water, or in an infulion of the plan- tain. This powder is brought into Kurope under the name oi terra ji^il/ata /. miiui. The woody bark of the fruit, and the fruit itfclf when fpoikd, helps to fup- ply the negroes with an excellent foap, which they make by drawing a ley fr»m the aflics, and boiling it with palm-oil that begins to be rancid. The trunksof fuch of thefe trees as are decayed, the negroes hollow out intoburying places for ihiir poets, nuificians, buffoons : perfons of thefe charafters they ellcem greatly while they live, fuppofnig them to de- rive their fupcrior talents from forctry or a commerce with demons ; but they regard their bodies with a kind of horror when dead, and will not give them burial in the ufual manner, neither futfering them to be put into the ground, nor thrown into the fea or any river, be- caufe they imagine that the water would not then nou- rifli the fifli, nor the earth produce its fruits. The bo- dies fliut up in thefe trunks become perfciflly dry wiih- out rotting, and forming a kind of mummies without the help of embalment. The baobab is very diflinft from the calabafli-tree of America, with which it has been confounded by fa- ther Labat. See Crescenti A. Culture. This tree is propagated from feeds, which are brought from the countries where they grow na- turally, being nativesonly of hot climates, the plants will not thrive in the open air in Britrin, even in fum- mcr. The feeds are therefore to be fown in pots,- and plunged into a hot-bed, where the plants will appear in about fix weeks, and in a (hort time after be tit to tranfplant. They muft then be planted each in a fe- parate pot, in light fandy earth, and plunged into a hot-bed, ihading them until they have taken root : af- ter which they Ihould have frefli air admitted every day in warm weather; but mull be fparingly watered, as being apt to rot. They grow quickly for two or three years, but afterwards make little progrefs j the losvcr part of the Item then begins to fv/cll, and put out la- teral branches, inclining to a horizontal polition, and covered with a light grey bark. Some of this kind of plants were railed from feeds obtained from Grand Cairo by Dr William Sherard, in 1724, and were grown to the height of iS feet ; but were all dellroyed by the fevere frofl in 1740; after which they were unknown in Britain till the return of Mr Adanfon to Paris in 17J4.

ADDISON (Lancelot^ fon of Lancelot Addifon a clergyman, was born at Monldiimealnn lie, in the pa- rilh of Croiby Kavenfworth in Wcftmorthiiid, in ilic year 163J. He was educated at Qiiceii's College, Ox- lord ;aud at t lie Rclloraiion of king Charles II. accept- ed of liic thaplainlhip of the garrifon of Dunkirk : but that fortrci's being delivered up to the Frcjicii in 1662, he returned to Kngland, and was foon after made chaplain to the gairilon of Tangier ; where he continued fcven years, and was greatly efteemed. In 1 670, he returned to England, and was made chaplain inordinary to the king ;but his chaplainlliip of Tangier being taken from him on account of his abfence, he found himfelf ilraitened in his circumilances, when he fcaibnably obtained thcredoryof Milflonin Wiltlhire, worth about I ioX.per anitiiin. He afterwards became a prcbtndary of Sarum j- took his degree of dodtor of divinity at Oxford ; and in 1683 was made dean of I.itclificki, and the ncxtyear archdeacon of Coventry. His life was cxem'plary ; his convcrfatiouplealing, and greatly inllrucfive ; and his behaviour asagentlenian, a clergyman, and a neighbour, did honour to the place of his relidencc. He wrote, i.

Addison (Joftph), fon of dean .Addifon the fub- jett of the lall article. He was born at Wilfton, near .•\mbre(bury, in Wjltlhirc, on the 11"' of May 1672 ; and not bti;ig thought likely to live was baptized tlie fame day. He received his tirft rudiinents of liis edu- cation at the place of his nativity, under the reverend Mr Nailh ; but was foon removed loSalilbury, under the care of Mr Taylor ; and from thence to tlic char- ter- houfc.wJiere he commenced his acquaintance with Sir Richard Steele. About fifteen, he was entered at Qiiccn's College, Oxford, where hcapplitd very dofc- ly to the ftudy of tlafllcal learning, in uhich he made a furprifing proficiency. In the year 16S7, Dr Lancaftcr, dean of Magda- len College, having, by chance, feen a Latin poem &f Mr Addifon's, was fo plcafed with it, thai he imme- diately i^ot hiui elected into tha houfe, where he look uphis (legrcesofha'.hclorarni mallerofarts. His Lstin pieces in the courfc of a few years, were exceedingly ad- * mired in buib. iviivei fitits: nor wercthcy lefs tftten.ed abroad, particularly by the celebrated Koileau, who is reported to have faid, that he would not have written againftPerrault.had he beforcklecnfuch excellent pieces AaJifon. by a modern hand. He pnblilhed nothing in Engiilh '' ^~ — before the twcnty-fecondyear of his age ; when there appeared a Ibort copy of verfcs written by him, and ad- dreffed to Mr Dry den, \\ >ich procured iiim great re- putation from the belt judges. This was foon follow- ed by a tranllation of the Fourth Gcorgic of Virgil, (omitting the llory of Arillaius), much commendedby Air Dryden. He wrote alio the Elfay on the Gcor- gics, prefixed to Mr Dryden's tranllation. There arc feveral other pieces written by him about this time ; among the refl, one d.lled the 3'' of April 1694, addrelfed to H. S. that is, Dr Sachevcrel, who be- came afterwards fo famous, and with whom Mr Addi- fon lived once in the greatefl friendlhip ; but their iu- limacy was fome time after broken off by their difagrce- mcnt in political principles. In the year 169J, he wrote a poem to king William on one of his cam- paigns, addrelfed to Sir John Somers lord keeper of the great leal. This gentleman received it with great pleafurc, took the author intothcnumber of his friends, and beflowtd on him many marks of his favour. Mr Addilbn had been clofely prcffed, while at the univerliiy, to enter into holy orders ; and had once re. folved upon it : but his great moderty, his natural dif- fidence, and an uncommonly delicate fcnfc of the im- portance of the facred function, made him afterwards alter his rcfohition ; and having exprefled an inclina- tion to travel, Jie was encouraged thereto by his patron abovcnuntioned, who by his intereft procured him from the crown a penlion of L.300/>£'r annum to fup- port him in his travels. He accordingly made a tour to Italy in the year 1699 ; and, in 1 701, he wrote a poetical cpiftle from Italy to the earl of Halifax, which has been univcrfally ellcemedas a moft excellent per- formance. It was tranllated into Italian vcrfe by the abbot Antonio Maria Salvini, Greek profelfor at Flo- rence. In the year i 70J, he publiihed an account of his travels, dedicated to lord Somers ; v/hich, though at firfl but inditi'crcntly received, yet in a little time met with its dcfcrved applaufe.. In the year 1702, he was about to return to Eng- land, when he received advice of his being appointed to attend prince Eugene, who then commanded for the emperor in Italy : but the death of king William hap- pening foon after, put an end to this affair as well as his penlion ; and he remained for a confiderable time un- cinjiloyed. But an unexpeflcd incident at once raifed him, and gave him an opportunity of exerting his fine talents to advaiitaj';c : for in the year i 704, the lord treafurer Godolphin happened to complain to lord Ha- lifax, that the duke of Marlborough's vicflory at Blen- heim had not been celebrated in verfe in the manner it deferved ; and intimated, that he would take it kindly, if his lordfliip, who was the knownpatron of the poets, would name a"gentlcman capable of doing juflice to lb elevated a fubjed. Lord Halifax replied, fomcwhat hallily, that he did know fuch a perfon, but would not mention him ; adding, that long had he feen, with indignation, nien of no merit n^aiiuained in luxury at the public expcncc, whilll thole of real worth aud mo- dtlly were fuff'ered to langtiilh in obfcurity. The treafurer anfwcred very coolly that he was fony there Ihould be occafioiii for fuch an obfcrvation, but that he would do his endeavour to wipe off fuch reproaches for the ADD r II' ] ADD t}}e future ; and he engaged his honour, that whoever his lordlhip named, as a perfou capable of celebraiing this victory, fliould meet with a liiitablc recoinpcncc. Lord Halit'ax thereupon named Mr Addifon ; inlilling, however, that the trealurer liiniftlf Ihould fend to himj whicli he promifed. Accordingly he prevailed on Mr Boyle (aftcrsvards lord Carlton) then clianccllor of the exchequer, to make the propofal to Mr Addifon ; which lie did in fo polite a manner, that our author readily undertook the talk. The lord-treafurer had a fight of the piece, when it was carried no farther tlian the celebrated fnnilie of the angel ; and was fo plcafcd with it, that he immediately appointed Mr Addifon a coniiniinoner of appeals, vacant by the promotion of Mr Locke, chofen one of the lords commillioners for trade. The Campaign is addrelfed to the Duke of Marlborough ; it gives a (liort view of the military tranfactions in 1704, and contains a noble dcfcriptiou of the two great actions at Schcllemberg and Blen- heim. In in I 705, he attended lord Ilalfax to Hano- ver; and the year following was appointed under-fecre- tary toSirCharles Hedges fccretary of Hate ; in which ortice heacquitted himfelf fo well, that the carl of Sun- derland, who fuccceded Sir Charles in December, con- liiuied ^lr Addifon in his employment. A tafle for operas beginning at this time to prevail in England, and many perfons having felicited Mr Ad- difon to write one, he complied with their requefl, and compofed his Rofamond. This, however, whether from the defeft of the mullc, or from the prejudices in favour of the Italian tafte, did not fuccecd upon the ftage ; but the poetry of it has, and always will be, juiUy admired. About this time. Sir Richard Steele compofed his comedy of the Tender Hulband, to which Mr Addifon wrote a prologue. Sir Richard fiirprifed him with a dedication of this play, and acquainted the public, that he was indebted to him for fome ot the mofb excellent ftrokes in the performance. The mar- quis of Wharton, being appointed lord lieutenant of Ireland in 1709, took Mr Addif(m with hira as his fecretary. Her majefty alfo made him keeper of the records of Ireland, and, as a father mark of her fa- vour, confiderably augmented the falary annexed to that place. Whilil he was in this kingdom, the Tat- ler Was firft publidied ; and he difcovcred his friend Sir Richard Steele to be the author, by an obfervation on Virgil, which he had communicated to him. He afterwards aflifted conl'iderably in carrying on this pa- per, which the author acknowledges. The Tatler be- ing laid down, the Spectator was fet on foot, and Mr Addifon furniflied great part of the moft admired pa- pers. The SpciJlator tnadc its firft appearance in March I 71 1, and was brought to a conclulionin September I7H- His celebrated Cato appeared in I7f?. He form- ed the delign of a tragedy upon his fubjeifl when he was very young, and wrote it when on his travels : he rctouclicd it in England, without any intention of bringing it on the ftage ; but his friends being per- fuadcd it would fcrve the caufe of liberty, he was pre- vailed on by their folicitations, and it was accordingly exhibited on the the.-ttrc, with a prologue by Mr Pope, and an epilogue by Dr Garth. It was received with the mod uncommon applaufc, having run thirty-five nights without interruption. The Whigs applauded every line in whicli liberty was mentioned, as a faiire An, on the Tories; and liic 'I orics echoed every clap, to ^ " " [how that the fatirc was iinfelt. When it was printed, notice wus given that the Q_aeca would be plcafcd if it was dedicated to her ; " but ashe h.id dclit;ncd that compliment cHcwhcre, he found himfelf obliged, "fays TickcU, " by his daty on the one hand, and his ho- nour on the other, to fend it into the world without any dedication." It was no lefs eftccincd abroad, ha- ving been tranflated into French, Italian, and German ; and it was acted at Leghorn, and fcvcral oihcr places, with vaft applaufc. The Jcfuits of Sr Omers made a Latin verfion of it, andthe ftudentsav'tcdit withgrsat magnificence. About this time, another paper called the Guardian was publilhcd by Steele, to which Addii'on was a prin- cipal contributor. It was a continuation of the Spec- tator, and was diftinguillled by the fame elegance and the fame variety ; but, in confcquence of Steele's pro- pcnfity to politics, was abruptly difcontinued in order to write the Engliflinian. The papers of Addifon are marked in the Spedator by one of the letters in the nar.ic of 67/», and in tiie Guardian by a Hand. Many of ihefc papers were written with powers truly comic, witli nice difcrimi- nation of characters, and accurate obfervation of na- tural or accidental deviations from propriety ; but it was not fuppofed that lie had tried a comedy on the ftage, till Steele, after liis death, declared him the au- thor of " TJie Drummer." This, however, he did not know to be true by any cogent teftimony : for when Addifon put the jday into his hands, he only- told him it was the w->rk of a grnilcinan in the com- pany ; and when it was received, as is confclicd, with cold difapprobation, he was probably lefs willing to claim it. Tickell omitted it in his colledion ; but the teftimony of Steele, and the total (ilcnce of any other claimant, has determined the public toaffign it to Ad- difon, and it is now printed with his other poetry. Steele carried "The Drummer" to the playhoufe, and afterwards to the prefs, and fold the copy for 50 gui- neas. To Steele's opinion may be added the proof fupplied by the play itfclf, of which the charadlers arc fii(^ as Addifon would have delineated, and the ten- dency fuch as Addifon would have promoted. It is faid that Mr Addifon intended to have compo- fed an Englifli didionary upon the pi. in of the Italian (Delia Crufca) ; but, upon, the .leath of the quern being appointed fecretary to the lords jullices, he had notleifure to carry on fuch a work. When the c;irl i>f Sunderland was appointed lord lieutenant of Irel::ud, Mr Addifon was again made fecretary for the afiaii:s of that kingdom ; anduponthe earl's being removed from the lieuicnancy, he was chofen one of the lords of trade. Not long afterwards an attempt was made to revive the Speftator, at a time indeed by no means favour- able to literature, when the fucceliion of a new family to the throne filled the nation with anxiety, difcord, and confulion ; end either the turbulence of the times or the faticty of the readers put a ftop to the publica- tion, after an experiment of 80 numbers, which were afterwards collected into an eighth volume, perhaps more valuable than any of thofc that went before it : Addifon produced more than a fourth part. In ADD f n AJilifon. In 171 J> hi began the Frcdioldor, a political pa- ' "^ ' per, which was much admired, and proved ot great ufc at that juiiAiirc. lie piiblilhcd alio, about this lime, verfcs to Sir Godfrey Kiicller upon the king's pidiirc, and fome to the priuccfs of Wales with tlie tragedy of Cato. liefore the arrival of king George he was made fe- crciary to the regency, and was required by his office to fend notice to Hanover thit the queen was dead, and that the throne was vacant. To do this would iiot have been diiRcuk to any man but Addifon, who was fo overwhelined with the grcatncfs of the event, and fo difbracted by clioice of cxpreliion, that thelords, who could not wait for the niceties of criticifm, called Mr Southwell, a clerk in the houfc, and ordered him todifpatch the mcllagc. Southwell readily told what was nccellary, in the common flylc of bufmcfs, and valued himfelf upon having done what was too hard for Addifon. In I 716, he married ihc countefs dowager of War- wick, whom he had folicitcd by a very long and anxi- ous courtlhij). He is faid to liavc iirll known her by becoming tutor to her fon. The marriage, if uncoa- tradided report can be credited, made no addition to his happincfs ; it neither found them nor made them equal. She always remembered her own rank, and thought herfclf intitled to treat with very little cere- mony the tutor of her fon. It is certain that Addifon has left behind him no encouragement for ambitious love. The year after, 1717, he rofc 10 his highed dcvalion, bci:ig made fecrctnry of Itate ; but isrepre- fcnted as having proved unequal to the duties of his place. In the houfc of commons he could n«t fpcak, and thcreliorc wasufclefsto the defcnceof the govern- ment. In the olHce he could not iliue an order with- out loling his time in quell of line exprellioiis. At lall, finding by experience his own inability for public buliuefs, lie was forced to folicit his difmilfion, with a pcnfioiT of ijool. a-year. Such was the account of iliolc who were inclined to detract from liis abilities ; but by others his relinquifhnuiu v.as attributed to de- clining hcaltji, and the ncrciruy of recefs and quiet. In iiis retirement, he applied bimfclf to a religious •Evi.lciices work *, which he hid begun long before ; part of nftheXiau which, fcarce tinilhcd, his been printed in his works. iUligion. He intended alio to have given an Englilh paraphrafe of fome of David's pfalms. But his ailments incrcafed, and cut ihort Uis deligns. ITe had for fome time been oppreCal by an ailhmaiic diforder, which was now ag- gravaii'd by a dro^ify, and he prepared to die conform- ably to his precepts and profeluons. He fent, as Pope relates, anicliage by the earlof Warwick to Mr Gay, dcliring to fee him : Gay, who h-'d not vilited him for fome time before, obeyed the fummons, and found himfelf received with great kindnefs. The purpofel'or which the interviev,- had been foliciicd was then difto- vered : Addifon told hi;n, that he had injured hi n ; but that if he recovered, he would recompciife him. Wli.-.t the injury was he did not explain, nor did Gay ever know ; but I'lppofed thit fome preferment defiu;n- fd for him had by Addifon's intervention been with- held. — Aiiolherdeath-bfd i;itcrview, of a morcfolemn iiaiurr,!S recorded: Lord Warwick wasayoungman of very irregr.'.ar life, and perhaps of ioofc opinions. Addi- fon, for whom he did not want rcfpc<.l,had very diligent- 2 ] ADD ly endeavoured to reclaim him ; but his argumcntsand AdUiion. cxportulations hadnocfied: One experiment, how- *— v— ever, remained to be tried. When he found his life near its end, he dircded the young lord to be called : and when he dclired, with great tcndernefs, to hear Jiis lafl injundions, told him, " I have fcnt for you that " you may fee how a Chrillian can die." What ef- fect this awful fcenehad on the carl's behaviour is not known: he died himfelf in a Ihort time. Having gi- ven directions to Mr Tickell for the publication of his works, and iledicated them on his deadi-bed to his friend Mr Craggs, he died June 17. i 7i9,at Holland- houfe, leaving no child but a daughter who is flill living. Addifon's courfc of life before his marriage has been detailed by Pope. He had in the houfc with him Rudgell, and perhaps Philips. His chief companions were Steele, LJudgell, Philips, Carey, Davenant, and Colonel Brett. With one or other of thcfc he al- ways brcakfaflcd. He ftudied all morning ; then din- ed at a tavern, and went afterwards to Button's. From the coffcehoufc he went again to the tavern, where he often fat late, and drank too much wine. Dr Johnfon, in delineating the character of Addi- fon, obferves with Tickell, that he employed wit on the fide of virtue and religion. He not only made the proper ufe of wit himfelf, but taught it to others ; and from his time it has been generally fubfcrvient to the caufe ofreafon and truth. He hasdilTipatcd the prejudice that had long conneded gaiety with vice, and eafinefs of manners with laxity of principles. He has rellorcd virtue to its dignity, and taught innocence not to be afliamed. This is an elevation of literary charadcr, " above all Greek, above all Roman fame." No greater felicity can genius attain than that of ha- ving purified intelledual pleafure,fepar3ted mirth from indecency, and wit from licentioufnefs ; of having taught a fuceefiion of writers to bring elegance and gaiety to the aid of goodiiefs ; and, to ufe exprcfTions yet more awful, of having " turned many to righte- " oufnefs." Asadefcriberof lifcand manners, hemuft be allowed to (land perhaps the firA of the firft rank. His humour, \\ hich, as Steele obferves, is peculiar to himfelf, is fo happily diffufed as to give the grace of novelty to domellic fcenes and daily occurrences. He never "outflcps the modelly of nature," nor raifes merriment or wonder by the violation of truth. His figures neither divert by diftoriion, nor amaze by ag- gravation. He copies life with fo much fidelity, that he can be hardly faid to invent ; yet his exhibitions have an air fo much original, that it is difficult to fuppofe them not merely the produd of imagination. As a teacher of wifdom he may be confidently follow- ed. His religion has nothing in it entluifiaftic or fu- percilious ; he appears neither weakly credulous nor wantonly fceptical ; Jiis morality is neither dangerouf- ly lax nor impradicably rigid. All the enchantuient of fancy and all the cogency of argument are employ- ed to recommend to tlie reader his real interelt, the care of plealing the Author of his being. Truth is fliown fomciimes as the phantom of a vifion, fomc- times appears half-veiled in an allegory ; fometimcs attrads regard in the robes of fancy, and fometimes flcps forth in the confidence of reafon. She wears a thoufand drclles, and in all is plealing. The ADD I »i3 ADD /\ddifo!t> The Doctor, Iiov/cvcr, li.ia rclitcd tl)c following a- ^ — nccJoif, which every admirer of Addifon, every man of feeling, nuiii be reluctant to believe. " Steele ( fays ihe Doitor), wliofc imprudence of gciicroliiy, or va- nity of ^Mofufion, kept him always incurably neccfli- tous, upon fomc prciiing exigence, in an evil lionr, borrowed an hundred pounds of his friend, probably without much purpofc of repayment ; but Addifon, who fecms lo have had other notions of a hundred pouncis, j;rcw impatient of dcla)', and reclaimed his Joan by an execution. Steele felt, with great fcnlibi- lity, tlic obduracy of his creditor ; but with emotions of forrow rather than of anger." It is much to be wiflied, fays Dr Kippis, that Dr jolinfon had produ- ced his authority fortius narration. It is very poliible, that it may be only 2 flory the Doctor had fcmrwhcre heard in converfation, and which is entirely ground- lefs: " and this I am t!ie rather inclined to believe, as I have been aruircd by one of the moft rcfptftable charai.1ers in the kingdom, that the fact hatii no foun- dation in truth." Mr Potter, in a late pnhlitation, hath informed us, that lie is told by the bcft authority, . tiiat the Uory is an abfol.itc falfchood. Mr Tycrs, in " An hiftorical ElTay on Mr A.Wi- fon," printed, but not puMilhcd, has mentioned fomc fads concerning him, witli which we were not before acquainted. Thefc are. That he was laid out for dead as foon as he was Ixirn : that, when he addrcfled his verfcs on the Englifh poets to Henry Sachcverell, he courted that gentleman's lifter : tliat, whenever Ja- cob Toiifon came to him for tlie Spediator, Baylc's F'rcnch Hiftorical and Critical DiSionary lay always open before him : that, upon his return to fengland, after hi-; travels, he difchargcd feme old debts he had contrat'lcd at Oxford, with tiie generofity of good intcreft : that he was put into plentiful circumftanccs by the death of a brother in the F:ift Indies: that, having received encouragement from a married lady, of whom he had been formerly enamoured, he had the integrity to refifc the temptation : that he refufcd a gratification of a three hundred pounds ba!.k-note, and afterwards of a diamond ring of the fame value, from a Major Dunbar, wliom he had cnf it, but I could not from n'yfclf ; and I hope I II1.1II always fear the reproaches of my own heart i:io"e than thofe of all mankind. In the mean time, if I can ferve a gentleman of i:ierit, and fich a charaflcr as vou bear in the world, i^e faiisfadion I meet with on Vol. I.' fiich an occafion is always a fufficicnt, ami the only re- ward to, Sir, your moft obedient, humble fervai't, I- Arcisor*." — Theanccdotcwhich follonswas tolj by the late Dr Hirch. Addifon and Mr lemplc Sian- yan were very intimate. Inihcfamiliarconvcrfations which pafTed l)etwefn thcni, they were accuftomcJ freely to difpi-tc each other's opii,';ons. CJpon fjme occalion, Mr Addifon lent Stanyan five hundred pounds. After this, Mr Stanyan behaved with a timid rtfcrve, deference, and refpet^ ; not convening with the fame frccdoin as formerly, or canvaifing his friend's fcnti- ments. This gave grezt unealincfs to Mr Addifon. One day, they happeuc J to fall upon a fubjec'l, on whicli Mr Stanyan had always been ufed ftrcnuoufly to oppofc his opinion. But, even upon this occalioa, he gave way to what his friend advanced, without interpofnig his own view of the m.ittcr. This hurt Mr Addifou ft) much, that he faid to Mr Stanyan, " Either cor.tra- diifl: me, or pay me the money." In TickeH's edition of Mr Addilon's wor!;3 tkere are fc vcnil pieces hitherto unmesitioned, viz.

The trapezi- forme, or black American maiden-hair, is a native of Jamaica ; and has Ihiiiing black flalks, and leaves of an odd (hape, which makean agreeable variety among other plants, fo is fbmelimes cultivated in gardens. Culture. The firA fpecies grows naturally out of the joints of walls, and filTures of rocks. It ought therefore to be planted in pots filled with gravel and limc-rubbilh ; w here it will tlirive much better than in good earth.

'I'he origin of adminillrators is derived from the civil law. 'Iheir eflablilhnicnt in England is owing to a flalute made in the 3 ill year of Edw. III. Till thcH, no ofiicc of this kind was known belidcthat of executor ; in cafe of a want of wliich, the ordinary had the difpofal of goods of perfons intellite, &c.

ADMIRABILIS sal, the fame with Glauber's fait. See Chemistry, n° 124. ADMIRAL, a great officer or magiflratc, who has the government of a navy, and the hearing of all ma- rine caufes. Authors a:e divided with regard to the origin and denominati'^'n of this important officer, whom we find eflabliflied in moft kingdoms that border on the fca. liut the mod probable opinion is that of Sir Henry Spelman, who thinks, that both the n.ime and dignity were derived from the Saracens, and, by reafon of the holy wars, brought into Europe ; for admiral, in the Arabian langnage, lignifies a prince, or chief ruler, and was the ordinary title of the governors of cities, provinces, &c. and therefore they called the com- mander of the navy by that name, as a name of dignity and honour. And indeed there are no inflanecs of admirals in any part of Europe bcfoie the year 1284, when Philip of Krance, whoha of ophiion tlut it " " ' \x ,:s lirftufeJ in llic itigii of Hciuy III. bccaiife iici- ilurtlic laws of Olcroii made in 1266, nor liraclon, who w rote about that liint, nial;c any mention of it ; and thai the term adKiml was not uftd in a eharter in the eighth of Henry III. wherein he granted this of- fice to Richard de Laccy, by thcfe words lMiiriiit,ia?n Angh^ ; but in the 56th year of the fame reign, not only the hiflorians, but-thc charters ihemfclves, very frequeiul) tifc the uord ad>iiiral. Anciently there were generally three or four admi- rals appointed in the Englillifcas, all of them holding x\\ca\^cc ilnrarti biiii pliuito : and each of them iiaving yariicnlar limits under their charge and government : as admirals of the tleci of lliips, from tlie mouth of the Thames northward, foiuhward or weflward. Befidcs thcfe, there were admirals of the Cinque Ports, as in the reign of Kdward III. when one \\ illiain Latimer wzi ii)\cA .Tdmiralis qiihiqtu portin/M ; and we fomc- limes find that one perfon has been admiral of the llcets to the fouthward, northward, and welhvard : but the title of adiniratii Aiiglite was not frequent till th e reign of Henry IV. when the king's brother had that title given him, which in all conimiirions aftcrsvards was granted to the facceeding admirals. It may be ob- fervcd, that there was a title above that of admiral of England, which was locurn-tii:e>is regis fhpcr tiian, the king's lieutenant general of ihefea ; this title we find mentioned in the reign of Richard II Before the ufe of the word Wwz/W was known, the I'iiie oi ciijlos i/iaris was made ufe of.

(Pope), the only Englilhman who ever had the honour of lilting in the papal chair. His name was Nichidas Brekefperc ; and he v^as Lorn at Langlcy, near St Alban's, in Htr!f.>rdn'.ire. His father having left liis family, and taken the habit of the nionallcry of St Alban's, Nicholas v.as obliged to fiibmit to the lowelt oiiices in that houfefor c!aily fjp- port. After fon;c lime, he Jeiired to takj the hatit m thatmonaltery, but wasrejecledby the abbot Iiichard. Upon thisherel'oiveJ to tryhistortune in another coun- t)-y, .ind accordingly went to Paris ; where, thougli in very poor cireumilauces, he applied hiinfclf to Lii lUiilies v\ ith great alFiduity, and made a wonderful pro- ficiency. But having (lill a ftrong inclinalidR to a re- ligious life, he left Paris, and removed to Provence, where he became a regular clerk in the monaftery of St Kufus. He was uoi iinn.cdiatcly allowed t« take the habit ; but palTcd fome time, by way of trial, in re- commending iiimfelf to the monks by a Uriel .-itentic!; to all their commands. Thisbchaviour, together with the beauty of his perfon, and prudent cor.vcrfation, rendered him ^ij acceptable to thofc religious, that af- ter fume li.-.ic they intreaied Jiim to take the habit of the canonical order. Here he difting liihed himfclf fo much by Iiis learning and ftrift obfervance of the mo- naftic diicipline, that, upon t!ie death of the abbot, he was ehofen fuperior of that houfc ; and we are told that he rebuilt tliat cojivent.

F'rom their appearance, it feems probable that the principal rampart was at lead 10 or 12 feet high, and the fouth one not much lefs ; but the north one was confiderably lower. From the dimen- fionsof the ditch taken as it paflTes through a lime-flone quarry near Harlow-hill, it appears to have been 9 feet deep, and 11 wide at the top, but fomcwhat narrower at the bottom. The north rampart was about 20 feet dLftant from the ditch.

Inno- cent VIII. fent him nuncio into Scotland and into France ; and after he had been clerk and treafurcr of the .npofiolic chamber, pope Alexander \'I. whofe fc- cretary he had been, honoured him with the cardinal's hat. His life was a continued fcene of odd alterations. He narrowly efcaped death theday Alexander VI. poi- foned himfclf by miflake.

It is reported that he ufcd to read in the night- time by the light of the lamps in the churches or llrects. He made a confiderablc progrefs in all the fcienccs ; led an exemplary life ; and there never was a man lefs intriguing and forward than he was. He took his degree of dodorof divinity at Louvain ; was loon after made canon of St Peter's, and profeffbr of divinity at Utrecht, and then dean of St Peters and vice-chancellor of the unirerlity. He was obliged to leave an academic life, to be tutor to the archduke Charles. This young prince made no great progrefs under him : however, never was a tutor more conli- derably rewarded ; for it was by Charles V.'s credit he was rai fed to the papal throne. LcoX. had given him the cardinal's hat in IJ17. After this pope's death, . feveral cabals in the conclave ended in the eletlion of Adrian, with which tlie people of Rome were very much difpleafed.

An .idiilterefs, by the Englilh law, undergoes no temporal punilhmeni whatever, except the lofs of her dower ; and (he does not lofe even that, if her hufband is weak enough to be reconciled to her, and cohabit with her after tlie offence committed. 13 Ed. I. cap. 34. But it is to be obferycd, that adultcreflcs arc fuch either by the canon or civil law. According to the former, a woman is an adultcrefs who, cither being herfcl f married, converfcs carnally with another man ; or being fmgle herfclf, converfes with a man that is married. According to the latter, ike is not an adul- tcrefs, if (he be not hcrfelf in the married fiate, though file converfes with a man that is. The crime, in this cafe, was more properlycalled (lupnun than adtiiteriuvi. Hence, among the Romans, the word adultera " a- dultcrcfs," ditfcred from pellex, which denoted a fin- gle woman who cohabited with a married man, and pil'.ix differed from cowa/Wwi/ which iignifiedher who had only intercourfc with an unm.irried man. The former was reputed infamous, ard the latter innocent. ADUTERATION, the ad of dchafiug, by an im- proper mi.xture, fomething that was pure and genu- ine. The word is Latin, formed of the verb adulterare, " to corrupt," by mingling fomething foreign to any fubflance.

ADULTKRINE, in the civil law, is particularly applied to a child ilRied from an adulterous amour or commerce. Adulterine children are more odious than the illegitimate offspring of llngle perfons. — The Ro- man law even refufes them the title of natural children ; as if nature difowned them Adulterine children arc not calily difpenfcd with for admiinon to orders. Thofe are not deemed adulterine, who are begotten of a wo- man openly married, through ignorance of a former wife being alive. By a decree of the parliament of Paris, adulterine children are declared not legitimated by the fubfequent marriage of the parties, even though a papal difpenfation be had for fucli marriage, wherein is a claufe of legitimation. Advlteri.\E Marriage s , in St Augufline's fenfe, de- note fccond marriages, contra,5tcd after a divorce. ADULTERY, an unlawful commerce between one married perlon and another, or between a married and unmarried perfon. Punilhmentshave been annexed to adultery in mofl ages and nations, though of different degrees of feve- rity. In many it has been capital ; in others venial, and attended only with (light pecuniary mulcts. Some of thepcnaUies areferious, andevcn cruel ; others ofajo- cofe and humorous kind. Even contrary things have been enacTcd as punilhments for adultery. By fome laws, the criminals are forbid marrying together, in cafe they became flngle ; by others, tluy arc forbid to marry any befidcs each other ; by fome, they are inca- pacitated from ever committing the like crime again ; by others, they are glutted with it till it becomes downright naufeous. Among the rich Greeks, adulterers were allowed to redeem tiiemfclvcs by a pecuniary fine ; the woman's father, in fuch cafes, returned the dower he had recei- ved from her hulband, which fome think was refunded by the adulterer. Another punillimcnt among thofe people was, putting out the eyes of adulterers. The .-Athenians had an extraordinary way of punifli- i ng adulterers, called -rap an x^@.,afa<^«T()((fiiiT/c,pradifed .'.Hlcad on the poorer fvirt who were not able to pay the fines. This was an awkward fort of impalement, per- formed by thurflii^ one of the largefl radilhcs up the amis of tiic adulterer, or, in dcfcft thereof, a tifii with a large head called mugil, " mullet." Alcaeus is faid to have died this way, though it is doubted whether the punifliment was reputed mortal. Juvenal and Ca- tullus fpeak of this cullom, as received alfo among the Romans, though not a.ithorifed by an exprefs law, as ii was among the Greeks. Vol. I. Therj are various conjectures concerning the inci- AJ'ahery. eiit punilliment of adultery among the Romans. Some ' '^~' will have it to have been made capital by a law of Ro- mulus, and again by the twelve tables. Others, th^c it was firfl made capital by Auguflus ; and others, not before the emperorConftantine. The truth ij, the pu- nilhmentin the early daysv/as very various, much be- ing left to the difcrction of the hufband and parcntsof the adulterous wife, who exerci fed it dittc-rently, rather with the filence andeounienance of the magillratc than any formal authority from him. Tliuswcare told, the wife's father was allowed to kill both parties, when caught in thcfacl, provided he did it immediately, kil- led both together, and as it were with one blow. The fame power ordinarily was not indulged the hufband, except the crime were committed with fome mean or infamous perfon; tho', in other cafcj, if his rage car- ried him to put them to death, he was not puniilicd as a murderer. On manyoccafions, however, revenge was not carried fo far ; but mutilating, caflrating, cutting off the ears, nofes, &c. ferved the turn. The punilli- ment allotted by the /t-.v Jn/ia, was not, as many have imagined, death ; but rather banifhment, or deporta- tion, being interdicled tire and water : though Oclavi- us, appears, in fcveral inftances, to have gone beyond his own law, and to have put adulterers to death. Un- derMacrinus, many were burnt at a flake. Conflantinc firfl by law made the crime capital. UnderConftan- tius and Conftans, adulterers were burnt, or fewed in facks and thrown into the fea. Under Leo and Mar- cian, the penalty was abated to perpetual banillimenr, or cuttingoff thenofe. Under Juflinian, a furtiier mi- tigation was granted, at leaf! in favourof the wife,who was only to be fcourged, lofe her dower, and be ihutup in a monaftery : after two years, the hufband was at li- berty to take her back again ; if hercfufed,lhe wasflia- vcn, and made a nun for life : But it ftill remained deat h in the hufband. The reafon alleged for this difference is, that the woman is the weaker velfel. Matthjeus de- claims againft the emprcfs Theodora, who is fuppofeJ to have been the caufe of this law, as well as of others procured in favour of that lex from the emperor. Under Thcodofius, women convicted of this crime were punifhed after a very lingular manner, viz. by a public conftupration ; being locked up in a narrow cell, and forced to admit to their embraces all the men that would offer ihemfelves. To this end the gallants were to drefs thcmfclves on purpofe, having feveral little bells faftened to their clothes, tlie tinkling of which gave notice to thofe without ot every motion. The cullom was again aboliflied by the fame prince. By the Jewiih law, adultery was puniihed by deatlt in both parties, where they were both married, or on- lythewomAn. The Jews had a particular method of trying, or rather purging, an adulterels, or a woman fufpefted of the crime, by making her drink the bit- ter waters of jcaloufy ; which, if Ihc were guilty, made her fwell. Among the Mingrelians, according toChardin, a- dultery is puniihed with the forfeiture of a hog, whicli is ufually eaten in good fricudlhipbetweenthe gallant, the adultrcfs, and the cuckold. In fome parts of the Indies, it is fiid any man's wife is permitted to pro- ftitutc herfelf to him who will give an elephant for the ufe of her ; and it is reputed no fniall glory to her to R have A D U [ 130 ] A D U AJuUcry. liavc Dccu liUcd fo high. Adultery is laid to be l"o *~— >» — - I'rcqiient at Ceylon, that not a woman but praiMifes it, uotwithflandiiig its bei:ij; jninilhablc with dcatli. A- mong the Japancfe, and divers other nations, adultery is only penal in the woman. Among the ,'\byllinians, the crime of the hiifband is faid to be only punilhed on the innocent wife. In tiie Marian illands, on the con- trary, the woman is not punilhable for adultery ; but if the man go aftray he pays fevercly : the wile and her relations wafte hislands, turn him out of his houfe, &c. Among the Chincfc, there is reafon to conclude that adultery is not capital ; for it is laid that fond pa- rents will make a coatrad for their daughters fn- lure hulbands to allow ihem the indulgence of a gal- lane. In Spain, they punilhed adultery in men by cutting oft' that pan wliich had been the inllrumcnc of the crime. In Poland, before Chrifliany was tllablilhed, they punilhed adultery and fornication in a very parti- cular manner: tlie criminal they carried to the mar- ket-place, and there f.ilUncd himby the telliclcs with a nail ; laying a razor within his reach, and leaving him under the iieceinty, cither of doing jullice upon hiinfclf or of perifliing in that condition. The Saxons formerly burnt the adultrefs, and over herafiies crcifted a gibbet, whereon the adulterer was hanged. In England, likewife, adultery, by the ancie:it laws, was fevercly punilhed. King Edmund the Saxon ordered adultery to be punilhed in the fame manner as homicide ; and Canute the Dane ordered thai a man who committed adultery Ihould be banilh- cd, and that the woman fliould have her nofe and ears cut off. In the time of Henry I. it svas punilhed with the lofs of eyes and genitals. In Britain, adultery is reckoned a fpiritual offence, that is, cognisable by the fpiritual courts, where it is punilhed by fine and penance. The common law takes 310 farther notice of it, than to allow the party grie- ved an aclion and damages. This practice is often cen- fured by foreigners, as making too light of a crime, the bad confequences of which, public as well as pri- vate, arc fo great. It has been anfwered, that per- haps tbis penally, by civil adion, is more wifely cal- culated to prevent the frequency of theoffence, which Di'jrht to be the end of all laws, than a fcverer punilh- cient. He that by a judgment of law is, according tocircumftances, llrippcJ of great part of his fortune, thirown into prifon till lie can pay it, or forced to fly his country, will, no doubt, in moll cafes, own that he pays dearly for his amulement. As to the moral turj/itudeof this offence, fome have vainly endeavoured to deny or explain it away by va- rious arguments, and even by an appeal to fcripture. On the part of the man who folicits the chalUty of a married woman, it certainly includes the crime of se- tiUCTioN, and is attended with mifchief flill more tomplicattd and extenlivc : It creates a new fufferer, the injured hufhand, upon whofe limplicity and affec- tion is inflifted a wound the mofl painful and incu- rabie that human nature knows. The infidelity of the VQMiu! is aggravated by cruelty to her shildren, who are generally involved in their parents fliamc, and al- ways made unhappy by their quarrel. It has been argued, that thcfe confequences ought lefstobe attributed to the crime than to the difcovcry. But, in the nrft place, the crime co;;ld not be difco- vert J uulcfs it were committed, and the commilllon is Adultery, never fccurc from difcovcry. Zi/Zy, If adulterous con- ^r— nedioiis were allowable whenever the parties could hope to efcapc deiedion, which is the conclulion to which this argument leads, the hulband would be left no other fecuriiy for his wife's chalUty, than in her want of opportunity or temptation : which would pro- bably deter moll men from marrying ; or render mar- riage a rtate of continual jealoufy and alarm to the huf- band, which would end in the (lavery and confinement of the wife. The i75arriagc-vow is " witneffed before God," and accompanied with circumflanccs of folcmnity and re- • ligion which approach to thp nature of an oath. The married offender, therefore, incurs a crime little fliort of perjury, and the feduftion of a married woman is little lei's than fubornation of perjury : — and this guilt is independent of the difcovcry. But the ufiial apology for adultery is the prior tranf- greflion of the other party ; and fo far, indeed, as the bad erterts of adultery arc anticipated by the conduft of the hulband or wife who offends firll, the guilt of the fecond offender is extenuated. But this can never amount to a jullification ; unlefs it could be Ihown that the obligation of the marriage-vow depends upon the condition of reciprocal fidelity ; a conllrudion which appearsfounded ncitherinexpediency,norin thetcrms of the vow, nor in the delign of the legillature which prefcribcd the marriage-rite. The way of confidering the ofi'cncc upon the ioonngof provocation and rttalia- tion, is a childilh trifiing with words. "Thou llialt not commit adultery," was an intcr- did delivered by God himfclf ; yet fcripture has been adduced as giving countenance to the crime. As Chrift told the woman taken in adultery," Neither do I con- dctiiii thee," we mult believe, it is faid, that he deemed her conduct cither not criminal, or at leaft not a crime of the heinous nature we reprefent it to be. But from a more attentive cxanunation of the cafe, it will be evident tliat nothing can be concluded from it favour- able to fuch an opinion. The tranfadion is thus re- lated* : ' Early in the morning Jefus came again in- ' to the Temple, and all the people came unto liim ; < and he fat down and taught them ; and the Scribes ''"'• ' and Pliarifces brought unto him a woman taken in ' adultery ; and When they had fet her in the midft, ' they fay unto him, Mafter, this woman was taken ' in adultery, in the very ad; now Mofes in the law ' commanded that fuch Ihould be Itoncd, but what ' faycfl thou ? This they faid tempting him, that they 'might have to accufe Iiim : but Jcfus Hooped down, ' and with his finger wrote on the ground as though ' he heard them not. So when they continued alking < him, he lift up himfelf, and faid unto them, He that ' is without fin amonglt you, let him firfl call a ' flonc at her ; and again he ftooped down and wrote ' on th^ground : and they which heard it being con- ' vided by their own confcitnce, went out one by one, ' beginning at the eldefl, even unto the lall ; and Je- ' fus was left alone, and the woman Handing in the ' midA. 'When Jcfus had liit uphirrfclf, and law none ' but the woman, he faid unto licr, Woman, where 'are thofe thine accufers ? Hath no man condemned ' thee ? She faid unto him.

' This ihey faid tcmptin": him, that they niight ' have to accufc him ;' trial is, to draw him into an exercife of judicial authority, that thty might have to accufe him belbrc the Ronian governor of iifurping or intermeddling with ilic civil government. 'This was their dcfign ; and Chrill's behaviour throughout the whole aftair proceeded from a know- ledge of this defign, and a determination to difcat it. He gives them at tiril a cold and fullcn n ceptioi;, well ftiitcdto the inliduousintcution with which they came : ' he Hooped down, and with his linger wrote on ' the ground as though he heard them not.' ' When ' they contintieti Jibing him,' when they tcaztd him to fpcak, he difmilicd rhem with a icbukc, which the impertinent malice of their errand, as well as thefc- crct charaftcr of many of them, dcicrvcd : ' he that is 'without lin (that is, this fm) among you, let him ' rirlt call aftoncat her.' This had its ctfeft. Siimg with the reproof, and difappointed of their aim, thty ftole away one by one, anti left Jefus and the woman alone. And then follows the cuflverfaiion, svhich is the part of the narrative molt material to our prcfent fubjccl. ' Jefus faith unto her, Woman, where are 'thofe thine accjfcrs .' hath no man condemned thte ? 'She faid, No man. Lord. And Jefus faid unto her. Neither do I condemn thee ; go and fin no more.' Now, when Chrift alked tlie woman, < Kaih no man ' coitdtjuncdlhct ? he certainly fpoke,and was under- flood by the woman to fpeak, of a legal and judicial condemnation; oiherwifcheranfwer, 'Nomau,Lord,' was not true. In every other fenfe of condemation, as blame, cenfur::, reproof, private, judgment, and the like, manyhad condemned her ; all thofe, indeed, who brought her to Jefus. If then a judicial fciuence was what Chrill meant by coiideimiing in the (jucfiion, the coramqn ufe of language requires us to fuppofc that he meant the fame in his reply, 'Neither do I con- ' demn thee :' i. e. I pretend to no judicial charaifler or authority over thee ; it is no office, or bufinefs of mine to pronounce or execute the fcntencc of the law. When Chrift adds, ' Go andiinnomore," heinerteft tells her that ftie had iinned already ; but as to the degree or quality of the fin, or Chrill's opinion con- cerning it, nothing is declared, or can be inferred, ci- ther way." It has been controverted, whether adultery may be lawfully committed in war, with the enemies wives ? The anfwcr is in thcnegativc, and the authorifcd prac- tice of civilized nations is agreeable to this. It has alfo been a famous qucftion, whetlicr it be lawful for a woman to commit adultery with the confent of her hulband, and for tlic procuring fomc great good to him ? St. Auftin apparently allows of it ; at Icaft docs not condemn it*. It has likcwifc been a difpute, whether it be lawful foroneof the parties married to commit adultery, with the confent of the other, for the fake of liaviiig chil- dren ? of which we liave iiiftance-s iuAbraliam, who, on this account, convcrfed with Haaiar : and likcwifc among the Greeks an J Romans. Pollnian, a German proferfor, has a dilfcrtation on the hulband's right 10 alienate his wife's body to another's ufe. It is much difputed whether adultery diflblvcs the bond of matrimony, and be a fufficicnt caufe of di- vorce, fo that tlie particsraay marry again. This w as allowee! in the ancient church, and is Aill continued in .".dultcry, the Greek, as well as the Lithcrca and Calviiiift AJvooic. churches. Romani.ls, however, difallow of it, and the * council of Trent even anathematized tliofe who main- tain it : though the canon of anathematization was mitigated in deference to the republic of Venice^ in fomc of whofc dominions, as Zan:, Cephaloaia, &c. the contrary ufage obtains. Theecclcfiallical courts iii England fo far agree with thofe of Rome, that they only grant a divorce i vKrfa et thuro, in cafe of adul- tery ; fo that a complete divorce, to enable the panics to marry again, cannot be had without an aifl of par- liament. Adultert is alfoufcd in ancient cuftoms, for the punilhment or fineimpofed for that offence, or the privilege of profecuting for it. In which icuituduiiL-- riu7/i amounts to the fame with what the Saxons cali /cgertuita. Adultery is fometimes ufed in a more extenfivc fenfe, for any fpecies of impurity or crime, againll the virtue of chaftity ; and in this fenfe divines under- Hand the feventh commandment. Adultery is alfo ufed, efpecially in fcripture, for idoktry, or departing from the true God, to the wor- Ihip of a falfc one. Adultery isalfo ufed, inecclefiaftical'writers, for a pcrfon's invading or intruding into a biOiopric du- ring the former bifliop's life. The reafon of the ap- pellation is, that a bifhop is fuppofed to contract a kindoffpiritual marriage with his church. The tranf- lationof a bilhop from one fee to another was alfo re- puted a fpecies of adultery on the fuppofition of its be- ing a kind of fecond marriage, which, in thofe days, was efteemed a degree of adultery. This conelulion was founded on that text of St Paul, Let a bijkop he thi h:ijba>:d of one 'xife, by a forced conftruclion of church for wife and of bilhop forhufband. Du-Cange. Adultery is alfoufcd, in ancient naturalifts, for the ai5b of ingrafting one plant upon another. la which fenfe, Pliny fpeaks of the adulteries of trees, arborum adulttria, which he rcprefents as contrary to nature, and a piece of luxury, or necdlcfs rctinc- ment. ADVOCATE, among the Romans, a perfon f^dll- ed in their law, who undertook the defence of caufes at the bar. The Roman advocates anfwercd to one part of the office of a barrillcr in England, viz. the pleading part ; for they never gave council, that being the bufinefs of the /vr//I',>,y;//r;. The Romans, in the firil ages of their ftate, hclj the profefTion of an sdvocote in great honour ; and the feats of their bar were crowded with fenarorsand confuls ; they, whofe voices comnLindcd the people, thinking it an honour to be employed in dcfcnJiag them.

Such in many cafes were kings, &C. when either they had been chofen advocates, or became fuch by be- ing founders or endowers of churches. Princes had alio another title to advocatefliip, fome of them pre- tending to be advocati nati of the churches within their dominions. Advocates, in the Englilli courts, are more ge- nerally called cointfel. See Counsel. Faculty oj AoyocATES, in Scotland, a refpciFlablc body of lawyers, who plead in all caufes before the Court of Sellion, Jufliciary, and Exchequer. They are alfo intitled to plead in the houfe of peers, and o- thcr fupreme courts in England. In the year 1660, the faculty founded a library upon a very extenfive plan, fuggefted by that learned and eminent lawyer Sir George M'Kenzie of Rofe- haugh, advocate to king Charles II. and king James Vll. who enriched it with many valuable books. It has been daily incrcalin.g fmce that time, and now con- tains not only the befl collection of law-books in Eu- rope, but a very large and (cltii collection of books on all fubjecT;s. Befidcs, this library contains a great number of original manufcripts, and a vaft variety of Jewiili, Grecian, Roman, Scots, and Englilh coins and. medals. A candidate for the office of an advocate undergoes three fcvcral trials: The firll is in Latin, upon the ci- vil law and Greek and Roman antiquities ; the fecond, in f.nglifli, upon the municipal law of Scotland ; and, in the third, he is obliged to defend a Latin thefis, which is impugned by three members of the faculty. Immediately before putting on the gown, the candidate makes a fliort Latin fpeech to the lords, and then takes the oaths to the government and de fideli. The faculty at prefcnt confifts of above 200 mem- bers. As an advocate or lawyer is efteemed the gen- teelefl profcflion in Scotland, many gentlemen of for- tune take the degree of advocate, without having any intention of praftifing at the bar. The circumftancc greatly incrcafes their number, gives dignity to the profcllion, and enriches their library and public fund. It is from this refpeftable body that all vacancies on the bench are generally fupplicd.

His buliucfs is to ait ~7~^ as a public profecutor, and lo plead in all cafes that concern the crown; but puticularly in Inch as arc of a criminil nature. The office of kiiig's advocate is not very ancient : It fceuis to have been eftabliflicd about the bcginnifigof ihc i6th century. Originally he had no power to profecutc crimes without the con- currence of a private party ; but, in the year 1597, he was empowered to profecute crimes at his own in- ilance. He has the privilege of pleading in court with liishaton. This privilege was firil granted to Sir Tlionias Hope ; who having.ihrce fonslords of fellion, it was thought indecent tliat the father (hould plead uncovered before the f)ns, who as judges fat covered.

ADVOWEE, iu ancient cuftoms and law books, denotes the advocate of a church, religious houfe, or the like. There wereadvoweesof cathedrals, abbeys, nionafteries, &c. Tlius, Charlemagne had the title of advowee of St Peter's; king Hugh, of St Riquier ; and Bolandus mentions fome letters of pope Nicholas, by which he conflituted king Edward the Confeflbr, and his fuccelTors, advowees of the monaflery aiWefl- jniuiler, and of all the churches in England. Thefe advowees were the guardians, proieftors, and admini- ftratorsof the temporal concerns of the churches, &c. and under their atithority were palfcd all contrads which related tothem. It appears alfo, from ihemofl ancient charters, that the donations made to churches wxre confcrredon theperfons of the advowees. They always pleaded the caufes of the churches in court, and (liflributtd juftice for tlicm, in the places under tlieir jurifdidion. They alfo commanded the forces fiirniiiicd by their monafleries, kc. for the war ; and c I'en were th circhampions, and fometimes maintained duels for them. This office isfiij to have beenfirft introduced in tire fourth century, in the time of Stillico ; though the Benedicli 'cs do not iix its origin before the eighth century. By degrees, men of the firll rank were brought intoit, as it was found necelfary cither to de- fend with arms or to proteft with power and authority. In fome monallcries they were only r'.Ued conprvators; but thefe, without the name, had all the functions of advowees. Tlicrc were al b fometimes fcveral fub- advowccs, or fub-advocates, in each nionaliery, who officiated inflead of the advov/ecs themlelves j which, however, proved the ruin of monafleries ; thofc infe- rior officers runniii>>; intogrcat abufcs. Hence alfo, hulbands, tutors, and every perfon in general, who took upon bin the defence of another, were denominated ./.■/t'OTU.vj, or advocates. Hence fc- veral cities had their advowees; which were cflablilh- oj long after the ccclcfiallical ones, and doubtlcfs from their example. Tlius wc read in hiftory of the aJ- Mwv/ti, vowecs of Augfburg, of Arras, &c. AUvowion. The f/./iia.'/afiunied the quality of advowees ; and ' ^~^ hence it is, that fevcral hiflorians of the eighth cen- tury confound the two funi^lions together, ilcnce al- fo it is, that feveral fecular lords in Germany bear mitres for tlieir crefls, as hiving anciently been ad- vow'ecs of the great churches. Spelman diflinguiflies two kinds of eeclefiafiical ad- vowees. — The one, of caufes or procelles adtccati caufantm; (lie other, of territory or lands, a./vccati flit. The former were nominated by the king, and were ufually lawyers, who undertook to plead the caufes of the monafleries. The other, which ftill fubfifl, and are fometimes called by their primitive name, advciuees, though more ufually patrons, were hereditary ; as being the founders and cndowcrs of churches, &e. or their heirs.

ADVOWSON, or Acvowzen, iu common law, fignities a right to prefcnt to a vacant benefice. Ad- vowfon isfo called, becaufe the right of prcfenting to the church was (irfl gained by fuch as w ere founders, benefactors, or maintainersof the church. Though the nomination of fit perfons to officiate in every dioccfe was originally in the bilhop, yet they were content to let the foundersof churches have the nomination of the perfons to the churches fo founded, relcrving to themfelves a right to judge of the fitnefs of the perfons fo nominated. Advowfons formerly were moflof them appendant to manors, and the patrons were parochial barons : the lordlliip of the manor and patronage of the church were feldom indifferent hands, until advowfons were given to religious houfes. But of late limes the iord- lliip of the manor and advowfon of the church have been divided. Advowfons are prefentjtivs, collativi, or donative : prcfintative, wliere the patron prefents or ofi'crs hi* clerk to the bilhop of the diocefc, to be inllitutcd Ih his church ; collathc, where the beneike is given by the bifhop, as original patron thereof, or by mcansof a right he has acquired by lapfc ; donative, as where the king or other patron does, by a fmgle donation in writing, put the clerk into polfcffion, without prefen- tation, iuflitution, or iuduition. Sometimes, anciently, ilie patron had the fole no- mination of the prelate, abbe, or prior : either by in- vcfliture (/. ^.delivery of a pafloral Raff), or by dircdt prefentation to the dioccfan ; and if a freeeledion was left to the religious, yet a cnn^c d'eltre, or li-cnce of eleftion, was firlt to be obtained of the patron, and the perfon ek:tcd was cijn'irnicd by him. If the founder's family became cxtiiu., the patronage of the convent went to the lord of the manor. Unlifs the fcveral colleges in the univerlities be reflrained in the number of advowfons they may receive, it i< argued they will in time acquire fuch a llock as to frultratc the defign of their foundation (which is the education of youth, by creating too quick a fuccelHon of fel- lows ; ADZ [ 134 ] MuA lows ; fo that there will not be in the college; a I'ufR- ll ciciit number ofpcrronsot'compttciit age, knowledge, Ad^a- anil experience, to inllruft and form the niiiidsot the ' youth In I'onie colleges the number of advowfoiis is iaiii to be already two thirds, or more, of the number of fellows. — It is ohjcded, on tlic other fide, that tire fucccllion of fcllevvs may be too flow as well as too quick ; whereby pcrfons well qualified may be detained folong in colleges as not to have llrcngth 01 activity enough left for the difchargc of parochial functions. Colleges holding more advowfons in number than moiety of the fellows, are not capable of purchafmg more. Grants of advowfoas by papiUs are void. 9 Geo. II. c. 36. 5 J. II Geo.

ADUST, Adustus, among phyficians, &c. is ap- plied to fuch humours as by lon|»heat become of a hot and fiery nature. Such is choler fuppofcd to be. Melancholy is ufually coufidered as black and adullbile. Blood is faid to be aduft, when, by reafon of fonic extraordinary heat, its more I'ubtile pans are all eva- porated, leaving the grollcr, with all the impurities therein, half torrihed. ADY, in natural liiftory, a name given to the palm- tree of the iilandof St Thomas. It is a tall tree, with a thick, bare, upright llcm, growing linglcon its root, of a thin light timber, and full of juice. The head of this tree (hoots into a vail number of branches, which being cut o(F, or an incifion being made therein, afford a great quantity of fwect juice, which fermenting fup- plics the place of wine among the Indians. The fruit of this tree is called by the Poriugucfe Car\ occs and Ca- rh'J; ; and by the black natives, Abauga. This fruit is of the fize and fhape of a lemon ; and contains a kernel, which is good to eat. The fruit itfclf is eat roaflcd, and the raw kernels are often mixed with man- dioc meal. Thcfe kernels are fuppofcd very cordial. An oil is alfo prepared from this fruit, which anfvvers the purpofe of oil or butter.. This oil is alfo ufed for anointing ftitt'and contraaed parts of the body. ADYNAMIA, in medicine, debility, or weakncfs, from fickncfs. ADYNAMON, among ancient phyficians, a kind of weak faftitious wine, prepared from mull boiled down with water ; to be given to patients to whom genuine wine might be hurtful. ADYTUM, in pagan antiquity, the mofl retired and facred place of their temples, into which none but thepriefts were allowed to enter. The Ssnf^um Sanc- torHi'iof the temple of Solomon was of the nature of the pagan adytum, none but the high pricft being ad- iviited into it, and he but once-year. ADZE, or Addick, a cutting-tool of the ax kind ; havinjr its blade made thin aud arching, and its edge at right an/lts to the handle ; chicly ufed for taking oft thin chips of timber or boards, and for paring away certain irret^ularities which the a.x cannot come at. The adze is ufed by carpenters, but more by coopers, as being convenient for cutting the hollow liJes of IE D I boards, &c. It is ground from a bafe on its infidc to Ae its outer edge ; fo that, wiicn it is blunt, they cannot Jl conveniently grind it without taking its helve out of -^'^"'"'*' the eye.

When the IHe of Angina was depopulated by a plague, his father, in compallionto his grief, changed all the ants upon it into men and women, who were called Mjrr/ndons, I'rom ftuffif^, an ant. The foundation of the fable is faid to be, that when the country had been depopula- ted by pirates, who forced the {c\v that remained to take liieltcr in caves, yEacus encouraged them to come out, and by commerce and induflry recover what they had loll. His charader for jullice was fuch, that, in a time of univerfal drought, he was nominated by the Delphic oracle to intercede for Greece, and his prayer wasanfwercd. See the article Algina.

To the aedilcs likcwile be- longed the care of the highways, public places, weights and racafures, &c. They alio fixed the prices of pro- vjllons, took cognizance of debauches, punilhed lewd womcn,andfuchp€rfons as frequented gaming honies. The cultody of the plcbifcita, or orders of the people, waslikewifc committed to them. They had the infpec- tionof comcdiesand other pieces of wit ; and were ob- liged to exhibit magniricent games to the people, at their ownexpcncc, whereby many of them were ruin- ed. To them alfo belonged the cullojy of the pie- bifcita, and the cenfure and examination of books. They had the power, on certain occaiions, 01 ilfuiiig edicts ; and, by degrees, they procured to thcmftlvcs a conlidcrable jurifdidiou, the cognizance of various caufes. Sec. ThisoiHcc ruined numbers by its txpcn- livcncfs J fo that, in Auguftus's time, even many fc- nators declined it on that account. Allthcfe fundions which rendered the aedilcs fo con- fidcrable belonged at firfl to the xdiles of the people, adtiiiplebeii, or miuorci : thefe were only two in niun- ber, and wcrefirft created in the fameyear as the tri- bunes : for tjie tribunes, finding themfclves oppreii'ed with the multiplicity of affairs, demanded of the fe- natc to have officers, with whom they might ijitruft matters of lefs importance ; and accordingly two aedi- lcs were created ; and lience it \v as that the arailes w ere elected every year at the fanicaircmbly asthc tribunes. But thefe plebeian aediles having refufcd, on a iJgnal occalinn, to treat the people with ihows, as pleading ihemfclvcs unable to fnppori the cxpence thereof, the patricians ma je an otter to Jo it, proviJcJ tliey would admit them to the honours of the adil^tc. On this occafion there were two aediles created, of tlie num- ber of the patricians, in the year of Rome ;!88 ; they Were called trdilis airuits, or wiijtra ; as having a right to fit on a curule chair, enriched w ilh ivory, when they gave audience ; whereas the plebeian asdilcs only fat on benches. — Belides that tiic curule asdilcs lliared all the ordinary fundions with the plebeian, their chief employ was, to procure the celebration of the grand Roman games, and to exhibit comedies, Ihews of gladiators, &c. to the people ; and they were alfo api)ointcd judges in all cafes relating tu tlie felling or exchanging cftaies. To caie thefe four firft asdilcs, Caefar created a new kind, called xdiLi ccniilei, as being deputed cliietly to take care of the corn, which was called dmuu ccrerit ; for the Heathens honoured Ceres as the goddefs who prefided over corn, and attributed to her the inven- tion of agricnlturc. Thefe aediles cercalcs were alfo taken out of the order of patricians. In the munici- pal cities there were sedilcs, and with the fame autho- rity as at Rome. We alfo read of an ledilts alimentarius, cxprcficd in abbreviature by JEdil. aihn. whofe bufinefs ftcms to have been to provide diet for thofc v. ho were maintain- ed at the public charge, though others aiDgn him a I ditfcreut office. — In an ancient infcriptionwc alfo meet >E-iilitiiin with ddiliof the camp, icdtlii cafimnnit. jtDILITIUM EDicTi!M,among the Romans, was that whereby a remedy was gi\en a buyer, in cafe a vicious or unfound beafl, or Have, was fold him.

And hence probably, in the prophet Uaniel, the he-goat is the fymbol of the king of Macedon. AEGEAN SEA (anc. geog.), now the Archipelago, a part of the Mediterranean, feparating Europe from Afia and Africa ; walhing, on the one hand, Greece and MacedoHia ; on the other, Cariaand Ionia. The origin of the name is greatly difputcd. feflus advan- ces three opinions : one, that it is fo called from the many iilands therein, at a dillancc appearing like fo many goats : another, becaufe y^igca queen of the A- niazons pcriflied in it: a third opinion is, becaufe A- gcus, the father ofThefeus, threw hinifelf headlong into it. AIGEUS, in fabulous hillory, was king of Athens, and the father of Thefcus. The Athenians having bafely killed the fon of Minos king of Crete, for carry- ing away the prize /roni them, Minos made war upon the Athenians ; and being vidorious, impofcd this fe- vere condition on yf^gcus, that he fliould annually fend intoCrete fcven of the nobleftof the Athenian youths, chofcn by lot, to be devoured by the Minotaur. On the fourth year of this tribute, the choice fell on The- fcus; or, as others fay, he himfclf intreated to be fcnt. The king, at his fon's dej'arture, gave orders, that as thefliip failed with black fails, it (hould return w ith the fame in cafe he pcriihed ; but, if he became victorious, he fiioiildchange them into white. When 1 hefcus re- turned to Crete, after killing the Minotaur, and for- got to change the fails in token of his vidory, accord- ing to the agreement with his father; the latter, who watched the return of the velTel, fuppofmg by the black fails that his fon was dead, calthimfelf head- long into the lea, which afterwards obtained the name of the JEgcan Sea. The Athenians decreed .igcus divine honours ; and facriliced to him as a marine dei- ty, the adopted fon of Neptune. ^.GIAS, among^yficians, a white fpeck on the pupil of the eye, wNfch occaiions adimnefs of fijht.

Sec jEa- cus. This illand was furroundrd by Attica,-the territory of Megara, and the I'cloponnefus, each diftant about 100 Haiia, or 1 2 milts and a half. In circumference it was reckoned 180 iladia, or 22 miles and a half. It was walhedonthf call and fouth by the Myrtoauand Crc- .tan feas. It is now called Eyiiia, or Eg'ma, thc^.foft and the i fliort. The temple abovemcntioned is (ituated upon the fummit of a juountain called faiihiUcnius, about an hour dillant from the Ihore. The A^ginetans affirm- ed it was crct^ed by /l^Acus ; in whofe time Flellas being terribly opprclfedby drought, the Delphic oracle was con lulled; and thcrtlponfe was, That Jupiter mull be rendered propitious by iEacus. The cities intreat- cd him to be their mediator : He facriticcd and prayed to Jupiter Panhellcuius, and procured rain. The temple was of the Doric order, and had fix co- lumns in front. Twenty-one of the exterior columns arc yet ftanding, with two in the front of the pronaos and of the polliciim, and five of the number which formedtherangesof the cell. The entablature, except the architrave, is fallen. The Hone is of a light bro%vn- illi colour, much eaten in many places, and indicating a very great age. Someof the columns have been in- jured by boring to their centres for the metal. In fc- vcral, the junction of the parts is fo exact, that each feems to conliA of one piece. This ruin Mr Chandler conllders as fcarcely to be paralleled in its claim to a remote antiquity. The lituation on a lonely mountain, at a diflance from the fea, has prcfcrved it from total demolition, amid all the changes and accidents of nu- jTierous centuries. Near the fliore is a barrow, raifed, it is related, for Phocus, tipon the following occalion. Telamon and Pcleus, fons of Abacus, challenged their half-brother Phocus to contend in the Pentathlum. In throwing the Hone, which ferved as a quoit, Pcleus hit Phocus, who was killed; when both of them fled". Afterwards, Telamon fent a herald to alFert his innocence, j^acus would not fuffer him to land, or to apologize, except from the vclfcl ; or, if hechofe rather, from aheap cafl up in the water. Telamon, entering the private port by night, raifed a barrow, as a token, it is likely, of a pious regard for the deceafed. He was afterwards condemned, as not free from guilt ; and failed away a- gain to Salamis. The barrow in the fecond century, when feenby Paufanias, was furroundcd with a fence, and had on it a rough Hone. The terror of fomc dreadful judgment to be inilitled from heaven had pre- fcrvcd it entire and unaltered to his time ; and in a country dcpapulated and negletled, it may ftill endure for many ages.

The goat Amalthca, which had fucklcd Jove, being dead, that god is faid to have covered his buckler with the (kin thereof; whence the appellation irgis, from «(f, aiy<,t,Jhc'-g(iat. Jupiter, afterwards rcAoring the beaft to life again, covered it with a new Ikin, andpla ccd it among the flars. As to his buckler, he made a prefent of it to Minerva ; whence that goJdcfs's buck- ler is alfo called a-gii. Minerva, having killed the Gorgon Mcdufa, nailed her head ill the middle of ihe;rgis, which henceforth had the faculty of converting into /lone all thofe who looked thereon; as Medufa herfelf had done durini' her life. Others take the aegis not tohave bcenabue^;ler, bnt a cuirafs, or breaft-plate : and it is certain the asgis of Pallas, defcribed by Virgil, A'.n. lib. viii. yer. 43y, mull have been a cuirafs ; fincc that poet fays cxjTcfs- ly, that Medula's head was on the breall of the goj- defs. But the cegis of Jupiter, mentioned a little high- er, ver. 3J4, fecms to have been a buckler : the words Cunifxl: tiigrantcvi vEgida ctiicuUret dextra, agreeing very well to a buckler ; but not at all to a cuirafs or brcaft-platc. Servius makes the fame dillinflion on the two paf- fagcs of Virgil : for on verfe ;J4, he takes the xgis for the buckler of Jupiter, made, as aboveincntioned, of the (Vin of the goat Amalthca ; and on verfe 455^ he defcribes the affgis as the armour which covers the bread, which in fprakingof men is called ci//^},and tgis in fpeakingof the gods.

Merc mos- the Athenians, under Conon, through the fault of his ^"""^ ' colleague Ifocratcs, received a lignal overthrow ficm the Laccdemoiiiarisunder Lyfaiulcr, which was follow- ed by the taking of Athens, and put an end to the Peloponnelian war. 'Ihe Athenian fleet having fol- lowed the Lacedemonians, anchored in the road, over agaiufl the enemy, who lay before Lampfacus. The Hilkfpont is not abcve two ihoufand paces broad in that place. The two armiesfceiiig theinlelves foncar each other, expected only to reft that day, and were in liopes of coming to a b.itllc on the next. Hut l.yfandcr had another dclign in his view. He commanded the feamen and pilots to go on board llicir galleys, as if they were in reality to fight (he next morning at break of day, to hold themfelves in rcadi- ncfs, and to \\ait his orders with profound (ilcnce. He commanded the land-army in like manner to draw up in battle upon the coafl, and to wait the day with- out noife. On the morrow, as foonas the fun was ri- fen, the Athenians began to row towards them with their whole fleet in one line, and to bid them defiance. Lyfand';r, though his lliips were ranged in order of battle, with their heads towards the enemy, lay Aill without making any movement. In the evening, when the Athenians withdrew, he did not fuller his Ibldiers to go afliorc, till two or three galleys, which he had fent out to obferve them, were returned with advice that they had fecn the enemy land. The next day palled in tlic fame manner, as did tlie third and fourth. Such a condu(;l, which argued referve and apprchen- lion, extremely augmented the fecurity and boldnefs of the Athenians, and infpired them with an extreme contempt for an army, which fear, in their fenfe, pre- vented from iliowing themfelves, and attempting any tiling. W'hilA this pafFcd, Alcibiades, who was near the fleet, took hori'e, and came to the Athenian generals ; to whom he reprcfented, that they kept upon a very difadvantagcous coafl, where there were neither ports nor cities in the neighbourhood ; that they were ob- liged to bring their proviflons from Cellos with great danger and difficulty ; and that they were very much in the wrong to fuffer the foldiers and mariners of the fleet, as loon as they were alliore, to Araggle and difpcrfc themfelves at thcirown pleafure, whilft dvcy Were faced in view by the enemy's fleet, accuAomed to execute the orders of their general with the rca- dieft obedience, and upon the IlighteA fignal.

The generals, efpecially Tydeus and Mcnan- der, jealous of their command, did not content them- felves with refufing his offers, from the opinion, that if the event proved unfortunate, the whole blame would fall on them, and if favourable, that Alcibia- des alone would have the honourof it; but rejecfled alfo with infult his wife and falutary council, as if a man in difgrace loA his fcnle and abililics with the favour of the commonwealth. Alcibiades withdrew. The fifth day the Athenians prefciited themfelves again, and offered battles retiring in the evening ac- cording to cuftom with more infuliing airs than the days before, l.yfander, as ufual, detached fome gal- leys to obferve ihem, with orders to return with the utinoft iE G Y [ 139 ] J^ M I ^gofpora- utmoft digilcnce when they law the Athenians land- mu* cd, and to put up a brazen buckler at each ihip's head I as foon as they reached the middle of the channel. ^gyP"' * Himl'clf in the mean time ran through the whole line in his galley, cxhortiuj; the pilots and otiiccrs to hold the fcimcn and foldicrs in readinefs to row and tight on thcfirft lignal. As foon as the bucklers were put up in the fliips heads, and the admiral galley had given the fignal by the found of. trumpet, the whole Hcct fet forward in good order. 'Jhi- land-army at the fame time made all pojiblc hafte to the top of the promontory to fee the battle. The (lr«it that fcparatcs the two continents in this place is about fifteen IlaJia, or three quarters of a league in breadth ; whichfpacc was prcfently clear- ed through the aftivity and diligence of the rowers. Conon the Athenian general was the firrt who percei- ved from fliore, the fleet advance in good order to at- tack him ; upon which he immediately cried out for the troops to embark. In the height of forrow and • trouble, fomc he called to by their names, fome he conjured, and others he forced to go on board their galleys ; but all his endeavours and emotion were inef- fcdual, the foldiers being difperfed on all iides. For they were no fooner come on iliorc, than fome ran to the futlers, fome to vvalk in the couJitry, fome to lleep in their tents, and others had begun to drefs their fuppcrs. This proceeded from a want of vigi- lance and experience in their generals, who, not fuf- petting the Jeafl danger, indulged themfclves in taking their repofc, and gave their foldiers the fimc liberty. The enemy had already fallen on with loud cries and a great noifeof their oars, when Conon, difengaging himfclf wiiliniucgalleys,of wliich numbcrwas the fa- cred fhip called the Puralian, flood away for Cyprus, where he took refuge with Evagoras. The I'elopon- ncfiaus, falling upon the reft of the fleet, took imme- diately the galleys which were empty, and difabled and deftroycd fuchas began to fill wi h men. The foldiers, who ran without order or arms to their relief, were ei- ther killed in the endeavour to get on board, or flying on fliore were cut to pieces by the enemy, who landed in purfuit of them. Lyfandcr took 3000 prifoners, with all tl'.e generals, and the whole fleet. After ha- ving plundered the camp, and fafltned the enemy's galleys to the flerns of his own, he returned to Lamp- facus amidft the found of flutes and fungs of triumph. It was his glory to have aichievcd one of the greatell military exploits recorded in hiftory with little or no lofs, and to have terminated a war in the fmall fpacc of an hour, which had alrc.idy laflcd 17 years, and which, perhaps, without him, had been of much longer continuance. itGYPT.

As to the unity of action, it is perfectly well prc- ferved in the Aineid. The fcttlement of A;neas, by the order of the gods, is conOantly kept in view. The epifodes are linked properly with the main fiibject. The nodus, or intrigue of the poem, is happily ma- naged. The wrath of Jnno, whooppofesj'Eneas, gives rife to all his difficulties, and connects the human with the ccieftial operations throughout the whole poem. One great imperfeclion of the /Eneid, h.owever, is, that there are aluioll no marked characters in it. A- chates, Cloanthes, Gyas, and other Trojan heroes who accompanied yEneas into Italy, arc inlipid figures. Even Apneas hiinfclf is without intercfl.

The """ ' death of old Priam, and thefamily-pieces of /Eneas, Anchifes, and Crcufa, are as tender as can be conceiv- ed. In the fourtli book, the u.i happy pallion and death of Dido arc admirable. The epifodes of Palkis and Evander, of Nifus and Euryalus, of Laufus and Mczentius, arc all fupcrlaiively fine. In his battles, \ irgil is far inferior to Homer. But in the important cp'fode, the defcent into hell, he has outdone Homer by many degrees.

The explication cj Enigmas makes a conliderablc exercife j and that one of the moii difficult and amu- ling, where wit and penetration have ihc largcft field. — By explaining an aenigma, is meant the finding a motto correfponding to the adion and perfons repre- fented in a picture, taken eitlicr from hiftory or my- tliology. The great art «f this exercife conlifls in the choice of a motto, which cither by itfclf, or the cir- cumftanccsof lime, place, pciibn who fpeaks, or thofc before whom he isfpeaking, may divert the fpedlators, and furnifli occafion for ftrokesof wit ; alfoin lliowing to advantage the conformities between the figure and thing figured; giving ingenious turns to the reafons employed to fupport what is adk'anced, and in artfully introducing pieces of poetry to illuflrate ihefubjecl and awaken the attention of the audience. As to the folution of aenigmas, it may be obfcr- ▼cd, that tbofe exprefledby figures arc more difficult to explain than thofc confifting of words, by rcafon images may figuify more things ihan words can ; fo that to fix them to a particular fcnfe, we mull apply every (ituation, fymbol, &c. and without omitting a circumflance. — As there arc few perfons in hillory, or mythology, but have fome particularcharaifler ofvicc or virtue, we are, before all things, to attend to this ckaralhr, in order to divine what the figure of a pcr- fon reprcfented in a painting fignifies, and to find what agrtemcTt thismay have with the fubjeft whereof we would explain it. Thus, if Proteus be reprcfented in a picture, it may be taken to denote ir.coKJhmcy, and applied citJKr to a phylical or moral fubjecl, wbofc chara'leris to be changeable ; e.g. an almanack, which fxprcflcs the weather, the feafons, heat, cold.llorms, aii.l the like. The colours of figures may alio help to unriddle what they mean: luA-r^, forindanee, isa mark of innocence, red of moJedy, green of hope, black of forrow, &c. When figures are accompanied with fymhoh, they are lefs precarious ; thcfe being, as it were, the foul of xnigmas, and the key that opens the niyflcryof them.

Though the atteniwnof philofophers has in all ages been eng.igcd in fome mcafureby inquiries concerning the nature of the atmof|diere, yet till within thefc lafl 50 years, little more than the mere mechanical action ofthis fluid wasdifcovercd, with the exigence of fome anomalous and permanently elaflic vapours, whofcpro- perties and relation to the air we breathe were aliiioll entirely unknown, ^\■ithin tlie abovemtntioncd pe- riod, hovvcver, tlic difcovcries concerning the conlli- tuent parts of the atmofphcrc itfelf, as well as the na- ture of the dilTercr.i j'ermancnlly clallic fluids which go under the general nameof the other 1905, gallons in 12 hoiirs, I'rom this the .lir is every moment purilicd by the afccnt of the va- pour, which flying off into the clouds, th'.;s leave* room lor the exhahtion of frclh quantities ; fo thai as the vapour is coiifiderably lighter than tlie common r.tmo- fphere, andofconfequeucc afcends with greater velo- city, t!if air during all this time is faid to be i!i\} , not- withflariding the vifl quantity of a'.jutou3 fluid that paflcs through it. Nor is it only from t!ic aqueous vapou/ tiiat the air is purified at this time. Much of that vapour arifing from decayed and putrid animal and vegetable fub- ■ '*'"'''"'"■ llances, and which by font e nioJern I'liilofopheis is called phlojijioti, attaches itftlf to cue aqueous vapour, and afcends along with it. Another part is abforb- od by vegetables ; for tke phlogiliic vapour, as is fliowuundcr Agriciii.ture,ii° J. is probably the food of plants. The phlogifiic vapours which afccnd along vnth the water, probably continue there and defcend along with the rain; whence the fertilizing quilities of rain-water above thofc of any other. Thus we may fee why a dry air, whether cold or hot, niiifl always be wholcfomc ; but as the atmofphere cannot always receixie vapours, it is obvious, that when great rains come on, efpecially if attended with heat, the lower regions of the air raufl be overloaded with vapours botli of the aqueous and phlogiliic kind, aiidof confcquence be very iinwholcfomt. But btlides the aqueous and phlogiftic vapours, both of which are fpecih'cally lighter than common air, there arc others, which, being fpecifically heavier, cannot be carried off in this manner. Hence thefc grofs vapours coniamiuatc certain places of the atmo- fphere, rendering them not only unhealthy, butabfo- lutcly poifonous. Ofthefeare, I. Sulphureous, acid, and metalline exhalations.

Of the fame kind arc the }/io- fctcs, orcminaiions of fixed air, which fomctimes pro- ceed fromokl lavas, or perhaps from fome other places even of the f.irfacc.

This dirt'eret'.ce indeed is exceedingly great, and has been varioudy calculated. Iliceioluseftimates the gra- vity of air to be to that oi water as i to 1000 ; Mcr- fennus, as i to 1300, or i to 1356 ; Lana,as i to 6..;o ; and Galileo, only as i to 400. Mr Boyle, by more ac- curate experiments makes the air at London to be to water as i to 983 ; and thinks, that, all things con- fidered, the proportion of r to icoo may be taken ai a medium. Jiut by three experiments made lince that time before the Royal Society, the fpceific gravity of the air was determined to be to that of water as i to 84D, S52, and 860. By a very accurate experiment, Mr. Haukfbee fixed the proportion as i to88j. But as all thefc experiments were made when tl;e barome- ter was at 29', inches, Dr Jurin fuppofcs, that, at a medium between heat a;'.d cold, when the barometer is 50 inches high, the proportion between the two fluids may be taken as one to 800 ; and this agrees with the oblervations of the Hon. Mr Cavendilh, made when the barometer was 594 inches, and the thenr.o- me ter at jo. By means of its gravity, the air prclfcs with great force upon all bodies, accordiitg to the extent of their farface. M. Pafcal has computed the quintityof this prelfure to be no Icfs than 2232 pounds upon every fquarc foot of furface, or upwards of 15 pounib on every fquare inch. According to fome cxprinients made by M. Amontons andde la Hire, a column of air on the furface of the earth, and 36 fathoms high, is equal in weight to three lines depth of mercury. F'rom the barometer, however we know that the vliok prellare of the almolpherc is very different; fometimc:; b.ing equal only to a column of 23 inches, and varying from thence to 31 inches. The whole quantity of prelliire mufl thus be be immeufe, and has been computed equal to a globe of lead 60 miles in dia- meter. By means of itsgravity , t!icatmofphe"rc accompliilies many ufefal purpofes in nature. It prevents the ar- terial vell'els of animals and the fap-vclFels of plants from being toomnch di:tcnded by the expanfivc power f whatever it is), which has a perpetual tendency to well them out. Thus we fee, that, in the operation of cupping, where the ^'refr.rc of the air is taken oS" from a pariiei.hr part, the rxpanfivc force inftantly ads, and fwellsoutthc velfcls toagreat degree.

Thus oils ami falts, whicli remain united in air, feparate as foon as iliat lluid is extracted. Hence alio, when hot water is put under an exhauftcd receiver, it boils vio- lenily ; becaule the prelllire of the air being now ta- ken of, the panicles of lleam, which cxided iiivilibly amonj; the water, and which the gravity oftheatmol- phere"prcventcd from liyingotf fo foon, are now hur- ried up with great velocity, by means of the exccliivc comparative gravity of the aqueous fluid. On the graviiy of the air depend the afcent of wa- ter in pumps.fyphons, &c. and likcwifc all the phtno- nomcnaofthe barometer. Belides its gravity, which the air has in common with water and other fluids, there is another which it has only in common with fleam or vapour. This is cnlleii its ilapkily ; by which, like a fpring it allows iifclf to be comprclfed into a fmaller bulk, and then rtturns again to its original li/,c upon removing the prelfure. The elafticityof the air was firfl afccrtaiucd by fomc experiments of lord Bacon, wiio, upon this principle, conftrufted the tirA thermometer, which he called his vitrui/icalciidarf. Of this power we have numerous proofs. Thus a blown bladder being fijueezed in the hand, we find the included air fcnlibly refill ; fo that, upon ccaling to comprefs, the cavities or imprclTions made in its furfacc arc readily expanded again and filled up. The ftruilure and office of the ///V-Pump depend on this elaflic property. Every panicle of air always cxertsa nifus or endeavour to expand, and thusilrives againll an equal endeavour of the ambient particles ; whole rcfiftauce happening by any means to be weak- ened, it immediaiely dilfufes itfelf into an immenfe extent. Hence it is that thin glafs bubbles, or blad- ders filled with air, and exa^ly doled, being included in the exhaullcd receiver of an air-pump, burllby the force of the air tliey contain ; and a bladder almofl quite flaccid, fwells in the receiver and appears full. The fame effect alfo takes place, though in a fmaller decree, on carrying the flaccid bladder to the top of an high mountain. It has been quellioncd among philofophers, whether this elaflic power of the air is capable of being deflroy- edordiminidicd. Mr Boyle made feveral experiments with a view to difcovcr how long air would retain its fpring after having alfumed the greatefl degree of ex- panlion his air pump would give it ; but he was never able toobfcrvc any feniible dimunition. Defaguliers found, that air, after having been inclofed for half a year in a wind-gun, had lofl none of its elaflicity ; and Robcrval, after preferving it in the fame manner for l6 years, obfcrved, that its expanfive projedile force was the fame as if it had been recently condenfcd. Iseveithelcfs, Mr Haukfbec concludes, from a later cxptriment, that the fpring of the air may be di/lurb- cd by a violent prcllure, in fuch a manner as to require fomc time to return to its natural tone. Dr Hales in- terred, from anumber of experiments, that the elafli- city of the air is capable of being impaired and dimi- nilhed by a variety of caufes. The weight or prelTure of the air has no dependence on its elafticiiy ; but would be the fame whether it had o Y. Sea. I. fuch a property or not. The air, however, being c- Of Air laflic, isneccilkrily afFe(5led by the prcffurc, which re- ' " i*^^"*^ duces,it into fuch a fpacc, that the tlalliciiy, which rc- atts agamll the conipnlliing weight, is equal to that weight, hi eticC;t,the law of this clailicily is, that it increafts as the denfiiy of the air increafcs ; and the deiility increafcs as the force increafcs by which it is prefVed. Mow there uiufl necelfarily be a balance be- tween the adion and rc-action : i. e. the gravity of the air which tends to comprefs it, and the elaflicity by which it endeavours to expand, mull be equal. Hence the elaflicity increafiug, or diminilhing univerfally, as the denlity lucrealesor diminiihcs, it is no matter whe- ther the air be coniprelfcd and retained in fuch a fpacc by the weight oi the atmofpherc, or by any other means ; it mufl endeavour in cither cal'e to expand wall the fame force. And hence, if air near the earth be pent up in a veflcl, and all communication with the external fluid cut ott, the prcllure of ihc inclofed air will be equal to the weight of the atinofphcre at the time the quaniiiy was conlincd. Accordingly, we find mercury iuflained to the fame height, by the elaflio force of air inclofed in a glafs vcllel, as by the whole atmofpherical prelfurc. On the fame principle air may be artificially coiidcnlcd ; and hence the llrufturc of theAiK-6'««. jg The utnioll limits to which air, of the dcnfity which Utmoft li- it potrellcsat the furfacc of the earth, is capable of be- mitsof its ing comprelled, have not been afcertained. Mr Boyle condcnfa- niadc it i 3 times more denfe ; Dr Halley fays that he "°" *"•* has feen it comprellcd fo as to be 60 times denfer than '"P*""""- in its natural Itatc, whi«h is farther confirmed by M. Papin and M. Huygeus. Dr Hales, by means of a prcfs, condenfcd it 38 times ; and by forcing water in an iron bailor globe, into 1551 tinics lets Ipace than it naturally occupies. However, Dr Halley has af- ferted, inthe Philofophical Tranfaillions, Abr. vol. ii. p. I 7. that from the experiments made at London, and by the academy del Cimcnto at Florence, it might be fal'cly concluded, that no lorce whatever is able to re- duce air into 800 times Icfs fpace than that which it naturally pollell'es on the furfacc of our earth. In an- fwer to this, M. Amontons, in the Memoirs of the French Academy, maintains, that there is no fixing any bounds toitscondenfation ; that greater and great- er weights willflill reduce itintolefsandlefscompafs : that it is only elaflic in virtue of the tire which it con- tains i and that as it is impollible ever to drive all the fire out of it, it is impoffiblc ever to make the utmoll condenfation. The dilation of the air, by virtue of its elaflic force, is found to be very furpriling ; and yet Dr. Wallis fug- gefls, that we are far from knowing the utmofl of which it is capable. It fever,:l experiments made by Mr. Boyle, it dilated firfl into nine times its former fpace ; then into 5 1 times, than into 60 ; then into 1 50. Afterwards it was brought to dilate into 8000 times its fpace, then into 10,000, and even at laftinto i 3,679 times its fpace ; and tliis altogether by ilsown expan- five force, without the help of lire.

Air is expanded one-third of its bulk by boiling water. Dr Hales found, that the air in a retort, when the bottom of the vellel was juft beginning to be red-hot, was expanded through twice its former fpace ; and in a white, or almoft melting heat, it occupied thrice its former fpacc ; but Mr Robins found it was cx]>anded by the heat of iron, jull beginning to be white, to four times its former bulk. On this principle depend the llrufture and oftice of the Thermometer. M. Amontons tirll difcovcrcd that air will expand in proportion to its denlity with the fame degree of lieat. On this foundation the ingenious author has a difcourfc, to prove " that the fpring and weight of the air, with a moderate degree of warmth, may enable it to produce even earthquakes, and other of the molt vehement commotions of nature." See the article jj Earthcjuake. General ef- The elalUc powcrof the air, then, is the fecond great lc&» of the fource of theeff'edsofthis important fluid.

Indeed, the degree of heat, and the air's gravity and dcnliiy, and confcqucntly its elafticity and expanlion, never remaining the fame for the Icall fpace of time, there muft be an incelfant vibration or dilatation and contraftion in all bodies. We obfcrvc this reciprocation in feveral inftanccs, particularly in plants, the air-veflcls of which do the office of lungs ; for the contained air alternately ex- panding and contrading, according to the incrcufe or diminution of the heat, alternately prell'es the vellels and eafes them again, thus keeping up a perpetual mo- tion in their juices. Hence we find, that no vegetation or germination will proceed /;/ vacuo. Indeed, beans have been ob- fervcd to grow a little tumid therein ; and this has led fome to attribute that to vegetation which was really owing to no other caufe than the dilatation of the air within them. The air is very inflrumental in the pro- duftion and growth of vegetables, not only by invigo- rating their feveril juices while i nan elafti'- active ftate, but alfo by greatly contributing in a fixed ftate to tlie union and firm connexion of tneir feveral conftitucnt parts. From the fame caufe it is, that the air contained in bubbles of ice, by its continual adion burfls the ice. Thus alfo, entire columnsof marble fomeiimes cleave in the wintertime, from theincrcafed elafticity of fomc little bubble of air contained in them. From the fame principle aiifc all putrcfartion and fermentation ; nei- ther of which will proceed, even in the beft difpofed fubjcdils, In vacuo.

It is known that iron '""*''■ and copper readily diiFolvc and become ruflyin air, ini- lefs well defended with oil. Bocrhaave alFures us, that he has fcen pillars of iron fo reduced by air, that they might be crumbled to duft between the fingers ; and as for co)>pcr, it is converted by the air into a fubftance much like the verJigril'c produced by vinegar. Mr Boyle relates, that in the fouthcrn Englilh co- lonies the great guns ruft fo i:i.ti., that after lying in the air for a few years, large cakes of crocus raartis may be feparated from them. Acofta adds, that in Peru the air diirolvcs lead, and confidcrably increafes its weight. Yet gold is generally eftcemed indilfoluble by air, being never found to contract ruft, though ex- pofcd to it ever fo long. In the laboratories of che- mifts, however, where aqua rcgia is prepared, the air becoming impregnated with a quantity of the vapour of this mcnftruum, gold contracts a ruft like other bo- dies. ,^ Stones alfo undergo the changes incident to metals. On ftouc». Thus Purbeck ftone, of which Salilbury cathedral con- lifts, is obferved gradually to become fofter, and to moulder away in the air ; and Mr Boyle gives the fame account of Blackington ftone. He adds, that air may have a confiderable operation on vitriol, even when a ftrong fire could ait no farther upon it. And he has found, that the funics of a corrofive liquor work more fuddcnly and manifelHy on a certain metal when fuf- tained in the air, than the mcnftrumn iifclf did, w liich emitted fumes on thofe parts of the metal which it co- vered ; referring to the effects of the effluvia of vinegar on copper. The dilfolving power of air is increafed by heat, and by other caufes. It combines with water ; and by ac- ccfs of cold, dcpofits part of the matter which was kept diifolved in it by a greater degree of heat. Hence the water, by being depofitcd and condcnfcd upon any cold body, fuch as glafs, &c. in windows, forms fogs, and becomes vifible. In the various operations of chemiftry, air is a very y -^-^ neceifary and important agent ; the refuli oi particular chemicll procelles depending on its prefcncc or abfencc, on its effefij of being open or inclofed. Thus, tiic parts of animals the air. and vegetables can only be calcined in open air ; in clofe vellels they never become any other than black coals. And thcfc operations arc effected by the changes to which the air is liable. .Many inftanccs mioht be adduced to this purpofe. Let it fuffice to obferve, that it is very ditticult to procure oil of fulphur, pa- catnpanam, in a clear dry atmofphere ; but in a thick moift air it may be obtained with greater cafe, and in larger quantities.

Wh ile the preceding difcoveries were making con- cerning the mcehanical and other propcniesof the air, little notice feems to have been taken cf the elementa- ry parts of the air itfelf, or the dilferent kinds of Huid which go under that name. It was known, indeed, that air was feparable from tcrreflrial bodies by means of fire, fermentation, &c. but this was commonly rec- koned to be the fame \\ith what we breathe. Van Helniont, a difeiple of Paracelfus, was the tirll who undertook to n'.ike inquiries concerning this Ipccics of air. He gave it the name of gas f)lvi.Jlre, Irom the Dutch woTy^ghnajl, figr.ifying fpirit ;and obfcrvcs,that fome bodies refolve themfelvts ahiiofl; entirely into it. " Not (fays he) that it had btcii aclually contained in that form in the bodies from which it was feparatcd ; but it was contained under a concrete form, as il iixed, or coagulated." According to this aiuhcr, the gas fylveftrc is the fanicv^ith what is feparated from all fubftances by fermentation ; from vegetables by the aftion cf fire ; from gun-powder when it explodes ; and from charcoal when burning. On tliisoccalion lie alFerts, that 62 pounds of charcoal contain 61 pounds of gas and only one pound of earth. To the etiiuvium cf gas he alfo attributes the fatal efFeols of the grotto del Cani in Italy, and the fuffocation of workmen in mines. He allcrts, that it is to the corruption of the aliment, and the gas difcharged from it, that we are to attribute wind, and the difchargcsofit from the bow- els. Upon the fame principles he accounts for the ftvellingof dead bodieswhith have remained for a time under water, and for the tumours which arifc on fome parts of the body in certain difcafes. He alfo '.eter- mines, that t his gas is diftl rent from the air we breathe ; that it has a greater affinity with water : and he ima- gined it might conlift of water reduced to vapours, or a very fubiile acid combined with volatile alkali. My Boyle repeated all Van I'clmont's experiments to more advantage th.ni hehimfclfhad perforined them ; but feems not to have proceeded further in his difco- veries than Van Hclmont did : only he found fome bodies, fu;h as fulphur, amber, camphor, &c. dimi- niCh the volume of air in which they burn.^ O Cr Sedt. ir. Dr Hales firll attempted to ddermine the quantity of air produced from dilierent bodies ; for which pur- pole he made experiments on almoft every known fub- Itance in nature, examining them by uiltillaiion fer- mentation, eonibuiUon, combinations, he. He alfo firll fufpeded, that the brilknefs and fparkling of the \saters called acdtHous, Vi-cre owing to the air they contained, liut netwithllanding all hisdifcovcricscon- cerning the quantity of elallic tluld obtained from dif- ferent bodies, he did not imagine there was any ellen- lia! dilFerence between this riuid and the air we breathe; only that the former was loaded \\ ith noxious vapours, lorcign to its nature. His lufpicion ceiicerning this- impregnation was confirmed by i\l. Vend, protellijrof chemiltry at Montpilier, in a memoir read before the "Royal Academy of iieicnccs in 1750. This gentle- man was able to difeiigagc the air from the 5ilt/.er v.-aters, and to meafurt its quaiitity ; vhichhccon- flanily found to amount to about one-fitih of its bulk. The water thus dcj'rivcd i>f its air became fiat, and ceafed to Iparkle ; the only diHerence then betwixt it and common water was, that the former contained a fmall quantity of fea-falt. Upon ihefe principles he attempted to recompofc Selt/.er water, by dilfolving in a pint of common water two drachms of ludile al- kali, and tlun adding an equal quantity of nariiie acid. The quantity of fea-filt produced by the union of ihefc two, he knew would prove equal to that contain- ed in a pint of Seltzer water ; and the effcrvtfcencc produced by the aiflion of the acid and alkali upon each other, he imagined, would produi^c air fuflitie]U for the impregnation of the water. In this he was not deceived ; the water thus produced was not only analogotis toiieltzer, but nuith nore llrongly impreg- nated will) air. Dr 131ack lirfl difcovcicd, that chalk, and the other earths reducible to quicklime by calcination, confillof an alkaline cs.riii by iifclf fohiblc in water, but which, combined with a large <|uan;ity of fixed air, becomes iufoluble ; loling the propeniesof quicklime, and af- fuming the natural appearance we obfervc ihofe earths to have when nt)t reduced into lime. The fame thing he difcovcrcd in niagnelia alba, and in alkaiis botii. fixed and volatile. On the fixed air contained in thcfc bodies, he found not only their property of cfTcrvef- cing with acids to depend, but likewife their niildncfs; both the alkalis and calcareous earth being highly caufiicwhen deprivtdof their fixed air. He alfo found, that this fl'jid, which he C2\\td. fixed air, had different degrees of affinity with different fubflanccs ; that it was Hrongcr w ith calcareous earth than with fixed al- kali ; with fixed alkali, than magnefia ; and v, ith mag- nelia, than volatile alkali. He aifofurpc(?}cd, thatlhe fixed air of alkaline falls unites itfelf with the precipi- tates of metals, when thrown down from acids ; and that the incrtafc of weight obfcrvable in thefe preci- pitates was owing to this caufe. But he was of opini- on, that the fluid which he called ^xt"/ o/r was very different from the common air we breathe ; and there- fore adopted the name of air, merely as one already cftablilhed, whatever impropriety there niitht be in the term. It was not long bef re the difcovrry of this fpecies of air fuggefled new theories in pliyliology and natural pbilofopliy. Mr Haller had inferred, from Dr I'ales's experiments.

But though thcfe opinions have (ince been found erroneous, the conclulioas drawn by him from his numerous experiments llill liold good, viz. that fixed air is an clailic fluid, very dittcrcnt from the common air we breathe: that it is poli'eli'cd of a llrong antifeptic quality, and may be introduced with fafcty into the intellinal canal, and other parts of the aiiiuial (Economy, where common air would have fatal clFccls; but is mortal if breathed into the lungs, &:c. In 1766 and 1767, Mr Cavendilli communicated fomc new experiments to the royal Society at Lon- don, wherein he determines tiie quantity of air con- tained in fixed alkali, when fully faturatcd with it, to be live-twclfthsofits weight, and fcven-twclfthsinvo- latilc alkali : that water is capable of a'oforbing more than its own bulk of this air ; that it has then an agree- able, fpirituous, and acidulous talle; and that it has the property of dilFolving calcareous earths and mag- nelia, as well as almoll all the metals, eipecially iron and zinc : that the vapour of burning charcoal occali- ons a remarkable diminution of common air, at the fame time that a coiMiderable quantity of fixed air is produced in liie operation, lie f.lfo found, that foLi- tion of copper in fpirit of fak, inlleail of producing in- flammable air, like that of iron or zinc, atri)rded a fpccics of air whicli lot its clallicity as foon as it came into coniaft with water. The dikovcrics of Dr Black concerning fixed air had not been long publiih-.-d, when they were violcntl/ attacked by fome foreign chcmills, while his cai;fc was 3s eagerly cfpoufcd by others. The principal oppo- nents were Mr Meyer apothecary at Ofnabrnck, Mr Crans phylician to his Ruliian ALijerty, and f.lr dc Smcthat Utrecht.

The circjmuan- ces w hich led him to the tiifcovcry, were his caving always procured inliammable air from fpirit of fait, by adding to it Ipirit of wine, oil of olives, oil of t'Trj-cn- tinc,thirco:'.l,pholphoru;,. bees wax, and even fulphur. Hence he fulpcctcd, that the common air we breathe might be compofcd of fomc kind of acid united with j. phlogilton. On this iuppolition he extracted air from Whence mercurius calcinatus p^rfi, by expoling it to the fccus 5r(l ex:nc- ofa burning-glafs 12 inches in diameter; and, hiving '^■'• repeated thcexperiment with red precipitate and mini- um, he found, that though a quantity of fixed air was always produced, yet after that wasfeparated, the re- mainder fupported iiame much more vigoroudy than common air ; for a candle burned in it with a rtimc very much enlarged, and with a crackling noifc, at the fame time that it appeared fully as much diniiniih- cd by the tell of nitrous air. \V hence he concluded, thaiit wasrefpirable ; and, on making thcexperiment, found that it a^'tiially was fo, for a moufc lived a full halfhourinaqujntity of this fluid ; which, had it been common air, would only have kept it a'liV-c half that time. No- did the animal fccm to be otherwifc irjureil thaii by the cold ; as it prefently revived on bringing it near the fire, and the remainder of the air fti'.fap- \ p-arcd better than that of the ?.tniofphcrc, when the t£!l of nitrous air was apj'licd to it. , This pure kind of air being difcovcrcd, the Do.".cr why na- next proceeded to nzmc'n d^pklcp'tjticat.d, from his ire.'. de- opinion that common air, in the"acl of burning, ab- pJilosiKi^^- forbed pl.logidon ; of conftqiience, he fuppofed, that "'*• which abfurocd the moll, or which inoft vigoroudy and for the grtateil length of time f :pportcd flame, was fuppofed 10 contain the fmallell qu.intity of this fub- lla.icc. In the courfc of his inquiries why this kind of air comes to be fo much dcphlogifticatcd, he fell upo:i a method of extrafling it from a great variety of fub- ftancesjviz. bymoiilcningthtmwiihfp:ri:ofnitre,and then dilUUing them witha ftronghcat. Thus hcob- Produced taincd it from ilowcrsofziirc,chalk,quicklime,llacked from a lime, tobjcco-pipe clay, riint, Mufcovy talcs, and even great vari- glafs. He then found, that by finiply diilblving any ''X oifnh- metal-in the nitrous acid, and then dillilling the foln- '^""'• lion, he coulj obtain very pure air: and Mr Warltirc found even the trouble of diftillaiiounnnectirary ; no- thing more being requiiite than to moilteiiVc'd lead with the fpirit of nitre, and then pour upon it the oil of vitriol, which inftantly i:ifengiv;ed the dephloTifti- cated air without applying any more heat than what was generated by the mixture.' jg \V hi:e difccvcries of this kind engaj:;ed Dr Prieulev Thii kind in Engl md, Mr Scheele was employed in a fin-.ilarman- of »'•■ J'f- ner in Sweden ; and had adually obtai;;cd the fame '■"°''""^"=''.^-- kind of air, without knowing anv thing of w-hat Dr^"}''^'' Prie.llcy had done.

Tlic port uir from riiuc haj in- c'ctdpirtly btcn obtai.icd by Dr H^lcs long before lliis time ; liiK-e lie intornis lu, that liilf a cubic inch of nitre yielded 90 cubic inches ol'air, which was un- doubtedly the fluid \vc Ipeak of; but as he neglected t'j profecutc the dilcovcry, nothing fanlur was known at that lime. As the nitrous acid was univcrfally concerned in the (irft pr6ccires for obtaining this kind of air, it was for fome lime generally believed to be a peculiar pro- perly of thai acid alone to produce it ; but the in- defatigable genius of Dr PriclUey fooi. found, that it might not only be procured where no niirous acid was employed, but where the fubllances were treated with vitriolic acid. It was indeed evident, from the very lirft experiment, that niirous acid was not ellcniially nccelfary ; fmce pure air was procured from precipitaie fir fi, in the preparation of \\ hich no nitrous acid is cmi>loycd. The AbbeKontana found, that 192 grains of this fubftance yicldcd65l cubic inches of dephlogi- flicaied air, at ihe fame time that the weight of it was reduced to 7885 grains, which is nearly the weight of that quantity of air. It had formerly been obfervcd, that the weight of mercury is augmented during its convcrlion into precipitate psr fe, as that of lead is by its converlion into minium. The experimentsjull now r.'.eniioned, therefore, Ihow, that during this procefs the air is decompounded ; the pure dcphlogillicaicd part of it being abforbed by the metal, and appearing agiinon the application of heat , and the fame appears to be the cafe with red lead, from the experiment of Mr Warltirc already mentioned. With regard to this Lift fubfl.ince, however, a very great fingulariiy is ob- fervcd ; viz. that when new ly prepared it yields none at all, and even for fome tii.ie after ihc produce is much fmaller than when it has been long kept. The reafon of thisfcems to be, that the minium fiill con- tains a confiderable quantity of phlogilion, which flics ofFintuthcatmofpherc by long keeping, a larger quan- tity of the dephlogiilicated part of the atmofphcre be- ing imbibed a the fame lime. The mode of applying heat has alio a very confiderable efTcfl on the quantity of air produced. Thus, Dr Prieflley remarks*, that aiii Obfcrv " from equal quantities of red lead, wiihout any mix- i i. 27. ture offpirit of nitre, andulingthe fame apparatus for 30 diftilling it, he obtained, by means of heat applied • Exper.

By heat alone, the Doftot found, that fedaiivc fall, 31 mangaiiefe, lapis calaminaris, and the mineral called Method of - - ■ ■ itVrom'TO- pill' gift'catcd air ; the firft indeed in very fmallqnan- rious fub- t'ty > and f 'mciimcs even of a quality very little fupc- flmccs. rior to common air. In thefe experiments, he made uft of fmall-bellied retorts of green glafs, which can fland the fire bell, containingabout an ounceof water, and having narrow necks 18 or 20 inches long. The Hibllance xo be examined was put into a retort of this proportion of ten to fix. The proportion of fixed air lap:i poni;rofui, luolfiam, or tuiiglieri, would yield dc- LOGY. Seel. Iir. kind, and theuexpofed 10 a red heat, cither in ftnd or Dephlogir- ovcr a lukcil tire, while the neck of the vtiltl was «i"'<-re deplilogiflicated air might be obtained, the Doc- tor determined to try whether the fame would not hold good with vitriolic acid alio. For this purpofe, he added more oil of vitriol to the rcliduutn of the laft- meniioncd experiment. When in a red heat with a glafs retort, it )iclded a quantity of vitriolic acid air, no fixed air, but aboat 24 ounce mcafurcs of dephlogifti- cated air : when, the retort being melted, a good deal of the air was neccllarily loll ; but, on refuming the procefs in a gun-barrel, he procured as much air as had been got before. — Purfuinglhefe experiments, he obiain.cd with common crull of iron and oil of vitriol, dephljgillicaied air at the firfl diftillaiion, and a great deal more from the reliduum, by pouring frelh oil of vitriol upon it. The fame proLluct he obtained from blue vitriol, fohuion of copper in the vitriolic acid, and from a folution of mercury in that acid. On this fubftance he remarks, that " cither by means of oil of vitriol er fpirit of nitre, it yields a great quantity of dephlogifiicatcd air : but wiih this diffiirence, that in the procefs w ith fpirit of nitre, almoll the whole of the mercury is revived (not more than a twentieth pan being loll, if the procefs be conduced w-iih care),; but in that with vitriolicacid,almo(lthe whole islofl." From the later cxperimcntsof Mr Lavoifier, however, it appears that the Doctor's procefs had not been con- ducted with futhcicni care ; as from two ounces of the dry fall formed by a combination of vitriolic acid with mercury, the former obtained 6 drachms 12 grains of running mercury, belides % drachms 58 grains of mer- curial fublim: tc of two ditTcrent colours. Dcphlogi- flicated air was likiwife obtained from pure calx of tin, or putty, mixed with oil of vitriol ; but none ill any trial with the marine acid, excepting when it was mixed with minium ; in which cafe the airobtainedwas probably that which the minium would have yielded wiihout any addition. Thercfult ofallihefe,and innnmcrableotherexperi- m cuts made by philofophers in different countries, was, that dephlogifticaicd air may be obtained from a vafl variety of mineral and metallic fubftances by means of the vitriolic and niirous acids. It now remained only How d«- to difcover in w hat manner this fluid, foeiTentiatly nc- phlogifti- celFary to ihe fupport of animal lit'c, is naturally pro- cated air is duced in quantities fufficient for the great expence of naturally it throughout the whole world, by the breathingof a- P''"""^' nimals, the fupport of fires, &c.

Among the vegetables employed on this occaiion, he found mint anfwer the purpofc very cltlc- • Ejpcr. tually. " When air," fays he*, "lias been frelhly and andObfcrv. ftrongly tainted with putrefaction, fo as to fmell vol. 1. p.

About eight or nine days after, he found that the air of the receiver into which he had introduced the fpri g had become refpi- rable ; for a moufc lived very well in this, whereas it 34 died the moment it was put into the other. fixperi- From thefe experiments the Doilor at hrfl conclu- mcutj ded, that in all cafes the air was meliorated by the ve- ceming y ~jtation of plants : but even in his tirft volume he ob- tgif- genhoufz's experiments, it will be ncceliaiy to relate t'catid ^ic fome obfervations made by Dr Prielllcy ; from wlii:h pfo'luctd it appears, that dephlogifticatcd air, in very conlidcr- ^'""^ *■'" able quantity, may, in certain circumllances, be pro- cured from water alone. The fubllance of thefe is, that water, efpccially pump-water, when cxpofed to the light of the fun, emits air (lowly : but after fome time a green matter appears on the bottom and lidcs of the glafs ; after which it emits very pwre air in great quantity, and continues to do fo for a very long time, even after the green matter has Ihown lomefymptoms of decay by becoming yellow. He obfervcd, that the water which naturally contained the greatefl quantity of fixed air, yielded alfo ihcgreated quantity of that which was dephlogiflicatcd ; but that the quantity ot the latter much exceeded that of the fixed air contain- ed even iu any water. Thelightof the fun was found to be an rlfential requifitc in the foriuaiionof thisair, as very little, and that of a much worfc quality, was produced in the dark.

The roots of the plants, he fays, when kept out of ground, generally yield bad air, and at all times contaminate common air, a few only ex- cepted. l'"lowers and fruits, in general, yield a very fuiall quantity of noxious air, and contaminate a great quantity of common air at all times, efpecially in the night, and when kept in th'j dark. Two dozen of young and fmall French beans, kept in a quart-jar of common air for a fingle night, co-.;tar.iinated the air to fu;h a degree, that a very lively chicken died by be- ing eontinci! in it kfs than half a minute. The ohfervations of Dr IngcnhoulV. on the whole, fays Mr Cavallo, clearly Ihow, << that the vegetation iiriiigen- of plants isone of the great means employed by nature hHufz's ex- to purify the atraofphcrc, fo as to couiit:raet, in great primciitr. meafure, the damage done by animal refpiration, com- buflion,&c. It may only be faid, that vegetation does not appear to be fufneient to remedy entirely that da- ma'^e." The Doclor himfclf, however, fpeaks very highly of the powers of vegetables in, this refpert. He intorms us,that their office in yielding dephlogil^icatcd air begins a few hours after the fun lias made his ap- pearance in thchorizon,or ratherafter it has palled the meridian, and ceafcs with theclofcof the day ; cxcept- ino-fome plants which continue it a fltort time after fun- fen The quantity of dephlogillicated air, yielded by plants in general, isgrcterin a clear day than when it isfomewhat clojily.

This gentleman has alio foniid, that feveral animal fubflances, as well as vegetables, have a power offepa- raiiiig dephlogiAicated air from water when expofed to the light of the fun, and tliat for a very great length of time. Not that the fame quantity of water will al- ways continue to fiirniili air; but the fame animal fub- itance being taken out, wadied, and again put into frclh water, fcems to yield dcphlogifticated air, with- out any kind of limitation. Raw lilk poifelfcs a remarkable power of this kind. D^piJio. To determine it, Sir Benjamin introduced 30 grains of gijij^ated this fubllance, previoully waflied in water, into a thin airprodu- glafs globe 44- inches in diameter, having a cylindrical ced by raw neck ^nhsofan inch wide, and twelve inches long, in- '•In- verting the globe into a jar filled with the fame kind cf water, and expoling it to the adion of the fun in the window. It had not been ten minutes in this ftuati- on, when the lilk became covered with an infinite number of air-bubbles, gradually incrcafing in lizc, till, at the end of two hours, the lilk was buoyed up, by their means, to the top of the water. By degrees they began tofeparate themfclves, and form a collection of air in the upper part of the globe ; which, when exa- mined by the tell of nitrous air, appeared to be very pure. In three dayshe had collected ^; cubic inches of air ; into which a wax-taper being introduced, that h.ad juft been before blown out, the wick only remain- ing red, it inftanily took fire, and burned with a bright and enlarged flame. The water in the globe apjieared to have loll fomething of its tranfpa.ency, and had clianged its colour to a very faint grecnilh caft, having at Sect. III. R O Dcphlogif- at the fiimc time acquired tlie fmtU of raw filk — This ticatcdAir. was fevcral times repeated with frcili water, retaining " " ' the fame lllk, and always with a fnialler refult ; but witli this difference, that when the fun Ihone very bright, the quantity of air produced was not only greater, but its quality fuptrior to that yielded when the fun's rays were feeble, or when they were fre- quently intercepted by tlying cloudb. "The air, how- ever, (fays he), was always not oiilymuch beiter-than common air, but even than that produced by the frefli Icavcsofplantscxpofcdinwater to the fun's rays in the experiments of Dr ingcnhoufz ; and, under the moll favourable circumllances, it was fo good, that onemea- fure ot it required four of nitrous air to faturate it, and the whole live meafures were reduced to i.^S-" No air pro- ^" experiment was next made in order to determine duccd ill thecrfctt of uarknefs upoa the proJuftionof air: and the dark, in this cafe only a few inconlidcrable bubbles were formed, which remained attached to tliefilk; nor was the cafe altered by removing the globe into a German flovc. Some llngle bubbles, indeed, iiad detached thenifelves from the filk and afceuBed to the top, but the air was in too little qoantiiy to be meafurcd or proved. — The medium heat of the globe, when expo- fed to the fun's rays, was about 90" of Fahrenheit, though fometimes it would rife as high as 96 ; but air wasfrequently produced, when the heat did not exceed EffccU of ^5 3ud 70°.— On reverfing this experiment, in order light with- to try the etfett of lighi without heat, it was found, •utheat. that by plunging the globe into a mixture of ice and water, which brought it to the temperature of about 50°of Kahrenheit, the produce of air was diniinilhcd, though it ftill continued in confiderable quantity. _. **.. • 1 Th' effedtof artilicial light, inllead of that of the Of artificial - .._'?.' light. fun, was next tried. For this purpofe all the air was removed from the globe ; and its place being fupplied with a quantity of frefli water, fo as to render it quite full, it wasagaininvertedinthe jar, and removedintoa dark room furrounded with fix lamps and refleftors; iix wax candles were alfo placed at different diilancesfrom three to fix inches from it, and dil'pofcd in fuch a man- nerasto throw the greatefc quantity of light polfiblc upon the lilk, taking care at the fame time that the water Ihould net acquire a grer.ter heat than 90". In this fituation llic lilk began to be covered with air- bubbles in about ten minutes; and in fix hours as much was collected as could be proved by nitrous air, whea it was found to be very pure. A frefl\-gathcred, healthy leaf of a peach-tree, and a ftcm of the pea- ' plant with three leaves upon it, furnilhcdair by expo- fure to the fame light, but in fmaller quantities than by the iiflion of the folar rays. The air produced in the dark, in whatever manner procured, was always in too fmall a quantity to be meafnred. In making thefe cxucriments, as it was found fomc- whattroiiblcforae to invert the globes in water, they wcrcatlalloulykcpt iiian inclined poihireonthe t.ible, as reprcfented in PI.

Finding that raw filk, expofed to the aiflion ol" light, produced fo rreat a quauaiy of air, ie was induced to fuljftltutird try whether Ibrae other fubftaiiccs might not be found (or raw out capable of doing the fame. Having therefore filk- Vol.. I.

The globe containing the fheep's wool began to yield air in three da^s; but feveral days of cloudy weather iiucrvcning, he did not remove it for fome time, when only ijihs of an inch of air was coUefted, which proved very pure when tried with nitreus air; but the wool, even in the moll favourable circumllances, never afforded more than one third of the quantity which would have been yielded by lilk. 2. The water with the eider- down began to furnilhair almoll immediately, and con- tinued to do foin quantities little Icfs than had been furnilhed by the filk, and nearly of the fame quality. One cubic inchand ihreequarttrsof thisair, furuilhtJ the eighth day from the beginningof the experiment, with three meafures of nitrous air, was reduced to 1.34. 3. The furof the hare pi oduced more air thaa the wool, but lefs than the cider-down. Two cubic inches of air were collected in four days ; which made its appearance in a different manner from that of the other fubftances, the air-bubbles being at confiderable diilancesfrom one another, and growing loan uncom- mon lize before they detached themfelvcs from the fur. The cotton yielded a conlnlerable quantity of air of a better quality than any of the former. Tiic ravelings of linen were very flow in furnilhing air, and produced but a fmall quantity ; only two cubic inches beinw col- ledUd in the fpace of a foi'tnight. This fubllance ap- peared to be the very re\'crfeof the hare's fur; for the air, inlUad of attaching and coUet^ingitfclf about the fubtlance in large bubbles, fearce ever ma3e its appear- ance in fufficient quantity to raife it to the top of the water. The human hair furniOied ilill lefs than the linen, and the produce wasof inferior quality, though ftill fuperior to the common atmofphere. In order to difcover the comparative finenefs of air produced from vegetables and from raw filk, a fmatl qiinntityof airfrom tlie llemof a pea-plant, which had four healthy leaves upon it, was proved with nitrous air, and found greatly inferior to that from raw lilk and feveral of the fubftances already mentioned. An entire plant of houfewort, of a moderate fize, furnilhed only jths of a cubic inch of air in feven hours, and that greatly inferior to common air; but the leaves a- lone afforded a much greater quantity, and o[ a.qua- lity greatly fuperior. Having proceeded thus far, it was next determined to afcertain how much air a given quantiiy of water would yield by expofiirc to tlic fun's rays. For this purpole, a globe of tine white, clear, and very thin glafs, containing 296 inches, being liiled with frelh Ipring water, and 30 grains of raw filk immerfed in ii, was expofed to the air for three days in the mouth ot May, but for the moll part rold and cloudy.

In tliis ex^>cri;iKm the air prodarcd wis every day removed from t'.ie globe, and its place f.iyi'litd willi \vat remain from firft to l.ift. The globe being therefore filled again, and the filk well wilhcd a;id replaceJ in it, the quantuy of air produced a- r.iounted in foardayb to ;o.i c.ibit inches ; a.id would probably h.-.ve been iiure co ili Icrable, had not the globe been unable to contain it along with the water, a id therefore there was a nccelfity for putting an end to the experiment. Thcqvia'iiy was fupcri -r to the former. — In this experiment the water had loft its tranfparency, and acq.iircd a grecnilhcafl ; a quantity of ycllowilh earth ivas precipitated to the bottom, and altarhcd iifelf fo ftroiigly to the glafs, that it could rot be removed v.ithout great diiiiculiy. On varying the experiment, by employ ing unwidi- eJrawfilk, it was found, that i 7 grains of it in 20 cu- bic inches of water, produced, for the firft 4 days, air of a worfc quality than the atmofphcre ; but afterwards yielded near two inches of a fupeiior quality. The quantity o! this air was fuperior to that in otlier expe- riments, tliough its quality was fumewhat inferior. Inrefleclingon the experiments above related, it oc- curred to Sir Benjamin, tliat the cotton-like fubftancc produced by l^c pof>fi/r/s t:'igra,a. fpecies of poplar tree, jnight be a proper fubftitute for the raw filk ; efpeci- «lly as he rccoUeded, tliat on rendering it very dry i ir fome other purpofe, fome parcels of it had quitted the plate on which they were laid, and mounted u]) to the top of the room. An hundred and twenty grains of tliis fubftance were therefore put into the large globe containing 296 inches ; but after cxpofure to the fun for fome hmirs the air produced, in quantity a- bout I Jihs of a cubic inch, was found to be little bet- ter tliavi phlogifticatcd air. In three days after, only one cubic inch was formed ; and this appeared to be completely phloriftif-ated. Next day, only a few iu- confiderable air-bubbles appeared ; but, the day fol- lowing, the water fuddcniy changed to agrcenilh eo- 1 )ur, and began all at once to give good air, aid in great abundance. This day 10.42 cubic inches were produced, and the next 14.34 The fame water con- tinued to furniih air for four days longer ; the whole quantity amounting to 44', cubic inches, tlic quality of which was fuperior to that of the air produced in former experiments. In fpeculatingon the caufcof this projiK^tion of air, it occurred to our author, that perhaps the quantity of it might be in proportion to the fnrfaccs of boh. In order toaf-crtain this, he viewed an hair of filk, and another of poplar-cotton, through a good microfcope, when the former appeared twice the diameter of the latter. The fpecilic gravity of the cotton was found of lobe nearly equivalent to th it of witcr; a:i!, by a Pcrhlogif- comparative view of the two througli a microfcope, ti'^'td Air. thefurfa.es appeared tobe'as loco to 5468. 1 y pro- "~ "' ceedingin thii calculation, iiappearc ! that the furiacc cf 30grai'i5of the cott m could not be Icf. than 66co fquarc inches, while that of a like q lantity of the filk a nounted to no more thin 476 rcnec it evidently appeared, that tlic produce of air from the two f b- Itance* w as neither in proportion to th' ir v\ eights nor their fiirfaces.

The globe being again fil- led w ith water, and expofed to the fun for two days, yielded 2 2 inches of air, of a qualiiy equal to 233. 4. A limilar globe, with poplar-co'ton which had been ufed informer experiments, gave 2.53 inches, of a qua- lity 280. 5. A fuiall globe of 20 inches, with 17 grains of raw (ilk, gave one cubic inch of air, of the quality 263. 6. A large globe of 296 iichcs, filled with frelh water, and a fmall quantity ufco'Jcrva rivu- Iciiii, gdiVC ij. cubic inch, of the quality only of 124. The water was changed to a brown colour. 7. On repeating the experiment \\ ith a fmall handful of the conferva, 1314 cubic inches of air were produced, of the qu.iliiy 24'). The water was very faintly tinged, towards the end of the experiment, of a greenilh call. 8. '1 he globe of 46 inches, w ith 30 grains of raw iilk ufed in many former experimenis, produced in two days 1.6 cubi" inches of air, of the quality of 204. 9. A globe of equal capacity, with 1 j grains of poplar-cot- ton, produced ill the fame tine 1.2S inches, of tlie quality 260. In both thcfe experiments, the water had acquired a faint greenilh eaft ; but the colour of that with the cotton was deepeft. On examining this wa- ter with a microfcope, it was found to contain a great number of animalcules exceedingly fnia'I, aid nearly of an oval figure ; that with the (ilk contained them likewife, but not in fiich numbers : however, our author affiires us, that in all cafes in which the water acquired a greenilh hue, he never failed to find thein ; and thinks, that from their prcfence alone, the colour of the water in the firfl inftanccuniverlally arofe. 49 As SirBenjamin was now more than ever embarralTcd Exp'-ri- with refpect to the lliare the filk and other bodies em- JT""" '^''''' ployed in thcfe experiments had in producing the air, ''"'S'*'*- he made the following experiment to determine I'nc matter : " Concluding (fays he), that if Iilk and other bodies.

With a view toafcertain this, the large globe bi in 5 made pcifccdy cUan, and lilkd with fpring-wattr, he introduced into it a qianiity of tlie fine thread of glafs commonly calli d fiuii.gUiJ's, futh as is uftd for making a brulli for ckauing jewels, and an rtitlci;.! feather fold by Jew pedlars. The rcfult of the cxpirimcit was, that the globe being t ^poftd to the fun, air- bubbles begjn almoft inftaiuly to make their appear- ance on the furface, and in four hours 0.77 of a cu- bic inch of air was produced, which, witli niirous air, fliowed a quality of 88 ; after which, not a lingle glo- bule more was procured, thouivh the globe was expo- fed for a whole week in fine funlhinc weather. Hence it appears, th.it fomctliing more than mere furface was wanted to produce dcphlogillicaiedair from svater by means of the fun's light. Thefollowin^ experiments were made with a view to determine the quantity and quality of air produced and -tion of light, actually A^i ceafe to furnilli air alur a certain time, yet that they regain this power after a dion interval, when they furniih (or rather caufe the water to furniih) more and better air than at firft ; which can hardly be accounted for upon the fuppolition that the air is elaborated in the vcifcls of the plant."

Thus we fee, that nature i^ provided with abundant refourccs for tlie fupplying of this pure part o( the at- mofphcre which is fiibjed to fueh continual w alle ; and • there is not tlie leall doubt, that in a great number of cafes the light of the fun produces pure air from wa- ter as well as from vegetables. Jt is probable, alfo, that even the waters of the ocean contribute towards this falutary purpofe j as Dr Dobfon of Liverpool found, that fea-watcr contained air fuperior in quality to that of the atmofpherc. The purification of a.mo- fpherical air by agitating it in water, will be confidered in a fubfecjuent feetion. As deplilogi.'ticated air is found to fupport animal life for a mucli longer time than common air, it has been fupjiofed thst it might anfwer valuable purpofcs large quail- j^ medicine, provided any cheap method of procuring *">'• it in large quantities could be fallen upon. With this view, Air Cavallo propofesto dillil it from nitre with a ftrong heat ; but the experiments already related cer- tainly point out an caller method, free from the ex- pence and trouble which mull necellarily attend every chemical operation of tliis kind. § 2.

Thofc in which it excels, are the fupport of dame and of ani- mal life. It is equally elalUc or rather'more fo, than common air ; as it likewife exceeds it a little in fpecific gravity, the proportion betwixt it and common air iseing that ofi6o to 152. On introducing a lighted candle into dephlogiflicatcd air, the flame not only grows larger, but becomes exceedingly bright ; and when the air is very pure, the candle burns with a crackling noifc, as if the air contained feme combuili- ble matter, at the fiimc time that the wax or tallow j5 walles furpriliiigly fafl. r«pliiogif- The heat of the tlamc is in proportion to its li^^ht. ticattd air Jf ue fill abladder with dcphlogi/lieated air, and then produces fa/^^n to its neck a glafs tube whofe aperture is drawn to a fine point, the dcphlogicated air, if driven out by prelfing the bladder, will augment the heat of a candle to fuch a degree, that if any fmall bits of metal, placed on a piece of charcoal, be held in the apex ofihe flame, they will almod inflanly be melted. Even grains of platina may by this means be melted ; and in a larger fire there is no doubt that the cffcels of burning mirrors might be equalled. On mixing dcphlogifticated and inflammable air, to- gether, an explollon takes place as on mixing com- jlamiuaHe mon and inflammable air, but with much greater vio- »■'■• lencc. If an ounce vial, which for thispnrpofe fliould be very .flrong, be filled with a little more than one- third of dephlo^iflicatcd andtherclt inflammable air, and the flame of a candle prefented to its mouth, it ■will explvdt uearly as loud as a fmall pillol. intcnfc heat, 56 Explodes, with in- J9 All phlogiflic procelfes are pronoted nmch better Dcpldogif- by dephlo^ikicatcd than comruou jii. i^r Prieltlcy titauJAir, put a quantity of pyrophorus intoo.ie ol the f;,iall jars ^ uicd for making experiments upon air in quiklilvir ; j^ then liUing up the vcll'el with that lluid, he inverted it Burns ve- in a bafou of the fame, and thiew in deplilogiilieateil iKuuntly air at diiitrenc times. It always occafioned a fudden with pyro- aiid vehement accenfion, like the tialhingof guii-pow- !>"<"■"»• der, and the air was gre.illy oiniinillied. ^g It iias been, almolt througiiout all ages, believed, Cftmnion mat combuilion in every inltance dimiuiahed common air is not air, or reduced it to a fmaller volume : but the late diminifln-d experimenuof .Mr Lavoilier have Ihown, that this is ^"i ''"'"'"S a miltakc ; and that in ordinary procelfes attended with the jiroduCtion of fixed and phlogillicatcd air, the quantity of vapour produced is equivalent to that abforbed, or other wife made to diiappear during the operation. With dephlogillicatedair the cafeis very dirt'creiit. * Mr Lavoilier hiving introduced a burning candle into a glafs jar filled With very I'U'c ^ir obtain- ^.^jj^^jjig. cd from calciu.aed mercury, a great iieat took place ; giuKmed which at lirll expelled a fmall quantity of the air ; but au- lulTers afterwards, when the candle was extiuguilhcd, it was dimiuutioo found that two-thirds of the bulk of air employed had been converted into tixed air, or a quantity of this kind of air equivalent to the former had been produ- ced. The remainder, after taking up the fixed air by cauflic alkali, was flill as pure as before. In ihc com- mon procelfes, he obferves, that notnuore than onc- tonih of the air employed is converted into fixed air. In this cxperin\ent, the fuperior gravity of fixed air, and the confequcnt condcnfation of the other, mull undoubtedly have produced fonic diminution in the volume of air, though Mr Lavoilier does not take no- tice of it. In other cafes, hbwever, the diminution is much more perceptible. Mr Scheele having intro- duced fome live coals into ainatrafs filled witli dephlo- gillicated air, found that it was diminillied by one- fourth of its quantiiy. Repeating the experiment with fulpluir, the flame beeanielarger and more vivid than in common air, and three-fourths of its quantity were loft. Putting a piece of pliofphorus into feveii ounce-meafures of this kind of air, flopping the mouth of the bottle with a cork, and fcttingfire to thephof- phorus within it, the phial broke to pieces, as foon as the flame wasextinguilhed, by the prelfure of the ex- ternal air. Repcatingrhe experiment with allrongcr vial, and opening it afterwards under water, the fluid rulhed into it in fuch a manner as almoft to fill it en- tirely. This extraordinary diminution was alfo per- ceived on felling fire to iiUlammableair in the dephlo- gifticated kind. The way in which he accomplilhed this was, by filling a matrafs with dephlogilHcated air, and invcrtingit over a phial containing an cff'Tvefcing mixture of vitriolic acid and iron-tilings plunged into a vcllel of hot water, andfurninied with a flendertiibe reachingabove the furface of the vellcl, asrcprefcnted Plate X. fig. 2. The inflammable air iiiuing from the orifice of the fmall tube, was let on fire previous to the inverlion of the maltrafs, and the mouth of the latter immerfed in the water; on which that fluid foon began to rife, and continuedto dofo ti'l fevcn-eighths of the velTcI were full. In cafes of flow combuftion, where common air is diniinifhed and phlogifticated, the dcphlogilUcaicd kind was found to be almoft en- tirely Seel. III.

A phial, containing 20 ounce nica- fiires of" citplilogifticatcd air, and inverted into a lo'ln- tion of litpur l.iipluiris, was entirely lilUd with the latter in the Ipaec of two days. The purity of dcphlogiilicatcd air js .ifcertaincJ by itb degree of diniiniaion with nitrous air; which, like that of the diniiniition by liver of fiilphiir, or o- thcrwU'e, is lobe coalidercd as a phlogifiic procefs, or kind ol biirniu;;, cfpecially as a conlideraLle degree of heat is thereby generated. Very great dilarenccs are perceived in tliis refpect ; and according to the quan- tity of diniinulion, the air is faid to be two, three, or four times bet.er than common air. It is not yet accurately determined how far this proportionable pu- rity extends. Dr FrieUley mentions fonie extracted from red lead five times as pure as common air. Another quantity, produced from aloUiticn ohiiercury in nitrous acid, was fo pure, that one meafurc of it mixed with two of nitrous air, which had been obtained in tiie firft part of the fame procefs, occupied only 0.0; of a meafure. " Repeating the experiment (fays he), I found, that two meafures of nitrous air were ratiicr more than fufRcir.nt to faturate one meafurc of the de- phlogiflicatedair; fo that poliibly, had the former ex- periment been made with more circumfpcctioii, the di- Jiiinution, extraordinary as it was, wouKI have been fomewhat greater. Indeed it cannot be fuppofed, that exactly two meafures of nitrous air fliould be the prccifc quantity lliat would afford the grcatcll diminu- tion. It (hould alfo be confidercd,- that a fmall por- tion of air might be yielded by the water in which the experiments were made. Upon the whole, therefore, I am inclined to think, that, were it pollible to make both thedephlogifticated and nitrousair in thcgrcatefl purity, and t;ien to mix them in fonic exact jiropor- tion, the aerial form of them both wwdd be dellroy- cd, the whole quantity feeming to difappcar, as in the mixture of alkaline and acid air." Notwithftanding this great degree of purity, the befl dephlogii;icated air is capable of being co.irami- nated by fome of the procelFes which alteti the com- mon air of our atniofphcre. Dr Pricftky having in- troduced a quantity of very dry, clean nails, into a re- ceiver tilled with dephlogillicatcd air, and inverted it in quickfilver, found, that about nine months after, one-tenth of the whole quantity h.id difappeared, the' he could not perceive any riilt upon the nails. The etfe.-ts of combultion have already been related, viz. as producing a great quantity of pure fixed air , but pn- trefailion and animul refpiraiion probalily t'ontaininatc it in a manner limiiar to that of atmofplurical air, , tliouirh few or no experiments feem to have been made on this fubjecl. Mr Cavallo, however, i. forms us, thai " when an animal is contined in a quantity of de- phlogifticated air, and is kept therein till it dies, that air is not rendered fo bad but that it will Hill be ca- pable of confiderablc diminution by nitrousair. This feems to (liow, tha' dephlngifticated air is fomewhat different from pure common air ; or that common air is ori;rin.^lly different fn-mdcphlogiftirated air, lower- ed by the addition of phlogifton. The phenomenon is certainly very remarkable ; and fomctimes a quantity of dephlogi?\icated air, after having been brriuhed by an animal till it died, will .ippear by the nitr(^ns tell to be even better than.cominoa air. When the expe- riment is performed over limc-witcr (to abforb the Dcphlogif- fixcd air produced in refpiraiion), the diminution by a ticatcdAir. mixture of^niirous air is lefs than it would otherwife ' be ; but it is llill diminilhed much more than common air after an animal has died in it ; which feems to in- timate, that the death of the animal in dephlogiltica- ted air is principally owing to the lixed air formed by the att of refpiraiion. It may be faid, that the in- fiammable principle difcharged through the Inngs of an anvj'.ial, being perhaps combined vith fome other principle, requires a longer time to combine with the dephlogifticated air than tlic phh'gilton of nitrous air; but this is only an hypothetical explanation of the abovementioned remarkable phenomenon, which re- quires many direct proofs." *i Dephlo^;;illicated air is much inferior to that of the ^^e-'-^^'on common atmofphtre in fupporling vegetable life. This ' ^,"1'?°"' has been afcertained by the experiments of Dr Prieft- phiogiftH ley, Mr Fontana, Mr Schccle, Dr Ingenhoufz, Scccatedaic Dr PrielUey took three fprigs of mint, and having put allihc roots into vials containing the fame pump- water which had been for fome time expofed to the atiuo- fphere, introduced one of them into a jarof dephlogi- fiicaied air, anotherin to ajar of common air, and a third into that which had been phlogillicated with nitrous air fevcrral months before, and in fuch a (late, tliatonc meafure of it, and one of nitrous air, occupied the fpacc of I = meafures. This was done in April ; and on examining them on the 12th of May following, it was found, that the plant in phlogillicated air had grown remarkably, much better than tiiatiu common air ; while the plant in dephlogifticated air had a very liekly appearance. Examining them on the 26th of the fame mom h , the appearance continued nearly as before ; but it was now found, that though the plant in phlo- giflicated air had grown fo w'ell, the air was not fen- (ibly improved by it, though the dephlogifticated air was injured by the plant which grew in it. 5 3.

It was not lor.g, how- ever, before this theory lyet with oppolition. Dr Prieftley himfelf, thouirh induced, from the wafte of the folid matter ufed in his experiments, to conclude that the air contained fome quantity of earth, was nevcrthelcl's unable, by any method he could think of to afcertain that quantity.

To thcfe MrKirwan r( plied in the manner rela'.ed in that ar- ticle. We Ihall here, however, give a quotation from Dr PrieRley as a kind of addition to Mr Watt's tefti- n-.ony on tjiis head, fo that the reader may be the bet- ter al le to determine the weight of the evidence on both fid< s. " At Mr Watt't requcfl (fays he), I endeavoured to afcertain the quantity of acid that was expelled from nitre, in procuring the dephlogifticated air from it. To do this, I put two ounces of purified nitre in;o a glafs retort, and rtctiving the air in joo oniice mcc- furcs of water, only filled each recipient h;'.lffull, and ajiiated the air very much in the water, in orJir to make the fluid in bibe as much as polliMe of the acid it contained. Notwithfanding this agitation, hosvtver, every velFt lof the air retained a ftropgfmell of the acid. The moment the air eeafed to come, I f.lled a large phial with the water, and carried it to Mr Watt, \\ h.> carefully < xamincd it: and in a pap/— from it follows the toiitrary rule -, being grcateil w hen the heat is moll vi.ilent and fuddc.'ly applied, and lefs when the fire is griiiually applied. On eakiningmeialsin dcptilogiuicaied air, very fm- guhr phcnoinei.a are obfervcd, which feem to throw great light upon the compolition of this iluid. " One of the moll limplc of all iihlogiilic proce-lfts (fays Lr Piieltlcy),is thatin which mciuls aremeUed indfplilc- giiticated air. 1 therefore'began with thi", with a view loafccrtain whether any water be produLcd when the air is made to difappear in it. Accordingly, into a glafs vellel, containing fevenouncc-meafures of pret- ty pure dephlogiliicated air, I introduced a quantity of iron turnings, which is iron in thin fm 11 pieces, ex- ceedingly eoiiViniem for thefe and many other expe- riments, having pre vioully made them, together wiili the vellil, the air, and the m^rcmy I'y which it was coniiUtd, as diy as I polii, ly could. Alfo to prevent the air from imbibing any moillure, 1 received it im- mediately in the vellil in which the experiment was ma V, from the procefs of procuring it fiom red prc- eiiitate, fo that it had never been in contacl with any 5- waiCr. I then tired the iron by means of a burning ivpKlogif- lens, and prtfently reduced the fevenouncc-meafures tica-ed air to 0.6 J of a mepfiirc ; but I found no more water af- '"'•''l"-*' t] ler this proccls than 1 imagined it had not been polfi- <^»''-=s '^1 blc for me to exclude, as it bore no proportion to the air which had difappeared. Eyamiiiing tlie n liduuia of the air, I found one-fifth of it to be fixed air ; and when I tried the puiity of that which remair.ed b/ the tell of nitrous air, it glf- f.ciiig fiOthii-.g the tlut could h-ivc in;Libcd it, ii oc- icatcJ Air.furrtd to D.e to Weigh the caljc into wbi.h the iron ^~~fil' tJii betii reduced ; and Ipreltntly foand, that the ITuhl.pif- dcfhlo^iliit.itcd air had aaiially been iir,b!bed by the ticatidair Lu'licd iron, in the lame manner as in.-ianiir.abjc air iir,bii)td by had been iir.bibed by ihc melted calces of metals in my •"*" former experiments, how ever ir.iprobiblc f ich aa ab- forption might have appeared a /"hri. In the (irft i.iftancc, about twelve ojuce-mtaiures of dcphh>giHi- catcd air hp.d dilappcarcJ, and the iron had giiacJ fjx grains in weight. Repeating the experiment very fre qutntly, I always found that other cjnaiitiiics cl i/on, treated in the fime manner, gained iiuiilar adJi.ions cf weight, which was always very nearly th.^.t of the g. air which had difappeared. l8car''We 'oc"tor had now 110 doubt that the two kir.ds of air had u.ijicd a::d formed either fixed air or v, atcr j and w ith a view 10 deterii.ine this point, he repeated the tx,>eriiiicnt in a vcU'el where thein'iammablc wascoiit'ncdby mcrcuty, loth th.c vcllcl and mercury having been peviou:ly r.iadc as dry as pofliblc. In the I'e circuinftaucts he had no fooner begun to hjat the iron, than the air was perceived to dimiiiifn, and at the finie tine the iiifidc of the veflel to become clo idy, with pirticks of dew that covered alnioft the whole of it. Thefc particles ly degrees gathered into drops, and ran down in all places, excepting thofe w hich were heated by the fan- beams. On ccUefting the water produ -cd i.rthis ex- periment, by menns of a piece of hltcring paper care- fully introduced to abfoib it, he found it to be as near- ly as pofTible of jhe fame w eight w ith that w hich h^id been loft by the iron ; and alfo in every cxperinitut of this kind, in which he atten.led to the circurr.rtance, he found that the quantity of iuflammablc air which had dif.ippeared w as about double that of the depLlo- p^ifticate J air fct loofe in the operation, f ippofmg that weight to have been reduced into air. Ihus, at 0:1: time, a piece of this (l.ig abforbcd j^ ounce-nicafures cf in.larnmable air, while it loft the weight of a'jont three ouncc-meafures of dcphlogifticited air, and the water coUcfted weighed two grains. Another time a piece of flag loft i.j grains, and the water produced V. as 1. 7 grains. In a third cafe, where 6^ oance-ntca- fuces of inflammable air were reduced to 0.92 of a mc::- fare, the iron hid loft th.e weight of 5.3 ouuce-.nea- fures of dephlogifticated air, or nearly two grains. Th c Do'itor having fuccceded fo well svith iron, next tried the calx of copper, or thofe f.aK-s which fly off' from it by hammering whiUl it is red-hot ; and found water produced in the inSammable air in the fame manner as when the fcalcs of iron were nfcJ. On u- fmg precipitate /t-r/i-, he imagined at firft that water was obtained from this fubftance alfo ; but on repeat- ing the experiment to more advantage he found no Hiore water than might be f ippofcd to have been con- tained as as extraneous fubftance cither in the in.'lam- mableairor in the red preci,Mtate. With iron, how- ever, the cafe was vaftly ditferent. As the Doctor had formerly fjtistied hi.nfeU' that inHamniabic air al- ways contains a portion of water, and alfo thjt when it has been fome time confined by water it imbibes more, fo as to be increafed in its fpeciiic gravity by that means, he repeated the cx,>eriment with in.iam- mable air which had not been conrined by that fluid, bit was re-civcd in velfel of dry mercury from the veflciinwhi -h it haJbeen generated . butinthiscafethc v.'aterwasprodu-ed,toappc:iranrc, as copiously as in the former expcrimcnr.

Expcri- As the experiments of Dr Prieftlcy tend very mtiitsof much to throw fomc light on the compolition of dc- ^i'"" *■',"""■ phlogiflicated air, we ihall here give an account of <)ifli,.ali proportion : and,fccoud- cins frum Jy, by fuppoling that there is no nitrous acid mixed tliefe expe- with or entering into the compofition of dephlogiUi- uients. cated air; but that, wii'-n the air is in fufficient pro- portion, part of the dephljgiiii'.-at'd air with which it is dcbafcd is, by the flrong aflinity of phlo^ifton to dc- phlogillicated air, deprived of itsphlogifton, and inrn- ed into nitrous acid ; whereas, when the dcphlogifti- cated air is not more than fufficient to confamc the in- flammable air, none then remains to deprive the phlo- gifticatcd air of its phlogiflon, and turn it into acid. — If the latter explanation be true, I think we mufl al- low that dcphlogifticatcd air is in reality nothing but d;phlogijikatcd watir, or water deprived of its phlo- giflon ; or, in other words, that water confifts of dc- jihlogifticatcd air unitrd to phlogifton. On the other hand, if the former explanation be true, v.e mud fup- pofe, that dephlogiflicatcd air confifts of water united to a little nitrous acid, and deprived of its phlogiflon ; but ftiU the nitrous acid in it muft only make a very fmall part of the whole, as it is found that the phlo- gifticated air into which it is converted is very fmull in comparifonof the dephlogifticated air. I think the fecond of thefc explanations feems much the raorclike- ly i as it was found that the acid in the condcnfed li- quor was of the nitrous kind, not only when the de- phlogifticated air was prepared from nitrous acid, but when procured from plants or turbith mineral. Ano- ther ftrong argument in favourof this opinion is, that dephlogifticated air yields no nitrous acid when phlo- gilticated by liver of fulphur; for if this air contains nitrous acid, and yields it when phlogifticated by ex- plofton with intlammable air, it is very extraordinary that it (hould not do fo by other means. Rut what forms a ftrongcr, and, I think, almoft decifive argu- ment in favour of this explanation, is, that when the dephlogifticated air is very pure, the condenfed liquor is made much more ftrongly acid by mixing the air to 80 be exploded with a little phlogifticated air." Dr Vrieft- The experiments of Dr Priedlcy alluded to were ley • cxpe- jhofc ill which inriammablc air was luppofcd by Mr runciits. Lavoilier to be procured from water by paiiing its /team through ret-hot iron tubes. It was foon difco- vered, however, by DrPriiftliy, that this inflammable air did not proceed from the water, but from the iron of the tube; and might bcobtaincd by tranfmittiag aqueous vapour through charcoal or iron placed in tub-.-sof cop- per, glafs, or earthen ware, made red-hot, but not through thtfe tubes by ihemfelves. In this cafe, the lofsof the water employed exceeded that of thcindam- inable air produced Ih the proportion of i.;; to 2 ; and the iron which had thus abforbed the water, aj'pearcd exactly fimilar to that which had been burned in de- 81 phlogifticated air in the manner already rc!a\ed. His Hiscpinion conclul:ons from thence are thefc: " Since iron gains conccnimg ,^g j-j,,,^ addition of weight by being melted in dc- thc compe- i , . „. , .

L O G V. wluii red hot, and becomes, abl have already obftrv- ed, the fanicfubftance in allrcfptcts, it is evident tb:il this air or water, as exifting in the iron, is the very fame thing; and this can harJly be explained but on the fiippofition that water confifts of two kinds of air, viz. inllammablc and dephlogifticated." Of thcfe proceflcs he gives the f.jllowing explana- tion: " When iron is heated in dephlogilUcatcd air, we may fuppofc that, though part of its phlogiftioK cfcapes, focnter into theconipolitionof the fmall qoan- tity of fixed air which is then procured, yet enough re- mains to form water with the dcphlogifticatcdair which it has imbibed, fo that this calx confifts of the inti- mate union of the pure earth of iron and of water; and therefore, v, hen the fame calx, thus faturated with water, is expofcd to heat in intlammable air, this air enters into it, deftroys the attraiflion between the wa- ter and the earth, and revives the iron, while tLe wa- ter is expelled in its proper form." The whole of the Dofior's opinions on the compo- nent parts of this kindof air, however, are fummcd up in the following fentence in VisObfirvaticiiis relating to Th:oty — "The only kind of air that is no»v thought to be properly elementary, and to conlift of a fimple fubftancc, is dephlogifticated air ; with the addition at Icaftofihe principle ofheat,concerningwhich we know very little ; and as it is not probable that this adds any thing to the weight of bodies, it can hardly be called an ^/tw/.'/./in their compofition. Dephh>gifticatcd air appears to be one of the elements of water, of fixed air, of all theacids, and many other fubftanccs, which, till lately, have been thought to be I'lmple." The experiments of the French philofophcrs were of the fame nature with thofe of >ir Cavcndifli, but con- ducted on a larger fcale. The inference drawn from them was the fame with that already mentioned, viz. tliat dephlogifticated and indammable air in all cafes arc the twoconftituent parts of water. This opiaioa is adopted by Mr. Kirwan in his TrcatiCe on Fhlcgijhtt. " The experiments of Mr Cavendiih, and of Wr Mongc," fays he, " appear to me to leave no room to doubt, that when very pure dephlogifticated and in- flammable air are inflamed, the product is mere wa- ter (a) ; for when thefc airs are employed in the pro- per proportion, only 0,02 of the mixture of both airs retains its aerial form. Now it is impoiliblc to lupptjfc that all the water obtained pre-exilled in thefc airs; that is, that 49 parts in jo were mere v.atcr. Notwithlianding thefc pofiiive conclufio?.s, how- ever, byfomcof the mofl refpcflablc names in Eng- land, the criJcnces adduced have been uuialisfac- tory to fonie French chcmiils ; who maintain, that Mrifrs Cavcndilh, Pricftlcy, and Kirwan, are totally miftakcii with regard to the produ(5iion of water from dephl'igitlicatcd and indammable air ; contcnding,tiiat the Wutcrobtained had prcviou'Iy exilted in the air, and was not originally pro.iuced in the oper.ition.

The greatell difficulty, however, which he fays he ever met with re- fpcdingtheprccedin>;theory,arofe from hisnever ha- ving been able to procure any water when lie revived red precipitate in inflammable air, or at Icall; no more than might have been fuppofcd to be contained in the inflaminablc air as an extraneous fubftanc;. In order to make the experiment with the fcalcs of iron and that with .the red pccipitaicas much alike as poifible, and compare them both to the greatcll ad- vantage, he made them one immediately after the other with every circumflance as nearly the fame he could. Theinriammablc air was the fame in both experiments, and both the fcales of iron and red precipitate were made as dry as pollible. They were heated in vclfcls of the fame fize and form, and equally confined by dry mercury : and yet with the former, water was produced as copioully as before, viz. running down the inlidc of the veficl in drops, when only four ounce-nieafurcs of inflammable air were abforbcd ; but though he heated the red precipitate till eightounce-meafures of thein- flammablc air wercabforbcd,and only 0.75 of an ounce- neafure remained, there was hardly any fenlible quan- tity of water produced, "certainly," fays he, " not on'c-tcnthof what appeared in the experiment with the fcales of iron. In this experiment there can be no doubt but that the dephlogilUcatcd air produced from the red precipitate mixed with the inrtammable air in the velTel ; and as no 'duuter equal to the weight of tiic two kindsof air was produced, they mull have formed fome moxcfoliJ fuhfiance, w hich ,in the fmall quantities I was obliged to ufe, could not be found. " The difficulty, with rcfpeol to what becomes of the two kinds of air, was not leilened by the attempts whicli I made to collect rdl that I could from repeated dccompofitionsof inflammable anddephlogiflicated air in a clofe velfel. As I had produced water in this pro- ccfs when nomore than alingleexplofion was made at a time, I thought that by continuing to make explo- fions in the f.inie velfel, the water would not fail to ac- cumulate till any quantity might be coUee^ed ; and I intended to have collefted a coufidcrablc part of an ounce. And as I would know exactly what quantity of air I dccompofed, I had no doubt of being able to licphlogif- afcertain the proportion that the w ater and air bore to ticatcd .^ir. each other. With this view a mixture was made of a " large quantity of air, one-third dephlogillicaied and two thirds inriammable,from iron andoilof vitriwl. — But though 1 had a fenlible quantity of water at the Jirll explolion ^in each of which between foiiraud five ounce-meafurcsoftiie mixture of air were ufed), I W'as furprifed to perceive no very fenlible incrcale of the quantity of water on repeating iheexplolions. Ha\ing therefore expended 48 ojnce-mcaluresof the mixture, the procefs w as difcontinucd ; and, coUeCling the wa- ter with all the care iliat I could, 1 found no more tlian three grains, w^hen there ought to have been eleven. " III this procefs the infidc of the veflTel was always very black after each explolion ; and when I poured in tlie mercury after the explolion, though there was no- thing viliblc in the air within the vellcl, there ilfucd 86 Incnnden- from the mouth of it a denfe vapour. This was the cafe, iliough I waited fo long as two minutes after any 'f^^\^ y^, explolion, before I proceeded to put in more mercury pourari- in order to make another ; w hith, if the vapour had fmg from been fleam, would have been time more than iuincienr ^vater. to permit it tocondcnfe into water. I even perceived this vapour when I jiad a quamity of water in the vel- fel, and tiie ex]ilolion was eonfcquenily made over it, as Well as in contatil with tlie lidcs of the velfel which Were wetted with it ; fo that, as this vapour had paf- fed through the whole body of water when the velfel Was inverted, it is prubable that it mull have coiililfcd of fomething clfe than mere water. But I w-as never able to collect any quantity of it, though it mufl have been fomething produced by theunionof theiwokinds of air." In order to colle<5t a quantity of this vapour, he con- trived an apparatus, which, by diffuling it through a thin glafs velfel, he fuppofcd would condenfe all the contents whether fluid or folid ; but after repeating the experiment as carefully as polhble, by taking 20 explolions, and repeating the whole feveral times o- ver, he could find nothing in the velfel belides a fmall quantity of water, which, addeii to that in tiie flrong veliej, came far ihort of the weight of the air that was dccompofed. . " Ail the eonjcdure," fay he," that I can advance, prieftfey'i in order to explain tliis phenomenon is, that fince foot coiiieaure yields pure air, part of the foot is formed by the union concerning of the dephlogidicated air in the atmofphere, and the this vapour, inflammable air of the fuel : hnl fmoks, which contains much/c';/, is foon difperfed, and becomes invilible in the open air. Such, therefore, may be the cafe here. The foot formed by the union of the two kinds of air, may be diffufcd through the air, in the velfel in which they are exploded, and be carried inviljbly into the common atmofphere ; which may account for my not being able to collcft any quantity of it in this appa- ratus." 88 Not difcouraged by this bad fuccefs, the Doftor at Unfuccef*- temptcd to collect this volatile matter by means of a fulattempts quantity of water incumbent upon the mercury in the tocolleA it.

This he ' " ' collected, and loiiud that it remained perlccHy black. upon the earthen velFcl in which the water containing it was evaporated ; which would not have been the cafe if the blackilh matter in the water had been that powder of mercury which is produced by agitating it in pure water : For that black mafs always became white running mercury the moment the water was e- vaporated from it. Ifafufficient quantity of this mat- ter could have been procured, he could have fatisticd himfelf whether it was foot or not. "That Water in great quantities (fays), is fomc- times produced from burning inriammable and dcphlo- able quin- ginicat^d air, is evident from the experiments of MeflVs edfrom^de- C-ivcndifli and Lavoificr. 1 have alfo frequently coUcft- phlogiftica- ed coniidcrablc quantities of water in this way, though ted and in- never quite fo raucii as the weight of the two kinds of flammable air decompofed. My apparatus for this purpofc was the following : Into the mouth of a large glafs balloon, I introduced a tube, from the oriticc of which there continually iflued inflammable air from a veiiel con- taining iron and oil of vitriol. This being lighted, continued to burn like a candle. Prefently after the lighting of it, the infide of the balloon alvvaysbecame cloudy, and the moiflurc foon gathered in drops, and fettled in the lower part of the balloon To catch what might iliue in the form of vapour, in the cur- rent of air through the balloon, 1 placed theglafs tube h, in which I always found fonie water condenled. It is very polhble, however, that in both thefc modes of experimenting, the water may be converted into a kind of vapour, which is very dificrent from fleam, and capable of being conveyed a great way through air, or even water, without condenfation along with the air with which it is mixed ; and on this account it may not be poITible, in cither of tliefc modes of experimenting, to collect a// the water into which the two kinds of air may be converted. The nature of this kind of vapour into which water may be chan- ged, and which is not rcadilycondcnfedby cold, is very little underllood, but w ell defervcs the attention of phi- lofophcrs. " That the water collefted in the balloon comes from the deconipolition of the air, and not from the frclh air circulating through it, was evident from pla- cing bills of hot iron in the place of the llamc, and f.uding that, though the balloon was as much heated by them as by the tlameof the burning of the inriam- mable air, and coafequently there miift have been the fame current of the external air through it, no moi- . Iture was found in the balloon." Sect. IV. Of TPhlogijlkated Air. Plilogiai- "^"^ univerfal prejudice in favour of the cxiflcnce caiionofair of that principal named Phlogijlsti, firfl fiiggelled by explained. Stahl, gave rife, on the firfl appearance of br I'rieft- Icy's difcoveries, to a theory, concerning the action of this fubflance upon air and other bodies. As it had been obfervtd, that air was dimiiiilhcd, in forae cafes at lealt, by burning, univtrfally by rc- (piraiiou, and by fonie otlier procellts, it was ima- gined that phlogifton was a body of fuch a fingular na- ture, that whcu mixed with air, it always diminiflicd 163 itsbiilk, infleadof enlarging it, which might havebcen Plilt.fifti- more nar,ii-:.lly expected from tiic mixture of any va- ' ■■.ted .^ir.^ ponr whatever. Itwasalfofiippofcd by fomc, that the '^ ' phlogillon was not only entirely devoid ofgra\ity, but thatit w'as a principle oipoftwe livity ; fo that the hiog:jiic [iroctjfes. Rcfpi- rationof animals was taken into the fame account; but neither in this, nor in combuflion, was it allowed that any kind of vital fpirit was abforbed by the blood, or feparated from the air by the burning body. On the contrary, it was ftrenuoudy argued, that all this was performed by ihcemijpou o( phiogijloii from the lungs or theinriamed fubflance, w-hich depraved tlie air, and diminifhcd it in bulk ; and as all air was fiippofed to contain phlogiflon, it was likewife imagined, that in all , cafes where air was mended, as by the growing of ve- getables, oragitation in water, the emendation was ac- complilhed, not by the emiflion of any thing into the atmofphere, but by the mere abforption of phlogirton. In other refpefts this fubflance was thought to be an exceedingly powerful principle in nature ; (he light of the fun itfelf and the cledric riuid being faid to be modi- fications of it, the different kinds of airs to be phlog- Jlic vapours, Sec. ; fo that the whole fyflem of nature feemcd ready to be abforbed by it at once. ^i The formidable powers of this principle were firftDovlrlue of checked by the difcoveries of Mr Lavoifier, though the p''Io).'ifion latter erred equally on the contrary lide ; and not con- "rpof"! by tent with keeping the phlogillic principle within due '^^ ^^'a'^" bounds, would needs deny its exiflence altogether *. '^•tee/i!^ In a treatife publilhed in the year 17S2, he lirft im-^j/fw. pugns Dr Frieflley's theory of refpiraiion, and denies that " the refpiraiion of animals has the propenv of phlogiflicatingairiuauiannerficiilar to whatisetfed- ed by the calcination of metals ar:d many other che- mical proceffes ; and that it ccafes not be refplrablc till the inftant when it becomes furch.irged, or at Icail fa- turated, w'ith phlogiflon." In order to difprove this afTcriion, he introduced ivfrl-'voi- four ounces of mercury to jo cubic inches of common fict\ expe- air, propofingto calcine the mct.il by keeping it for 12 rimenu on days in a heat almoll equal to that which is neceifary "■•alcinatiou to makeit boil. After the expiration of the appciiit- °'^ ""^'^l' ed time, 4J grains of precipitate pcrf^ were formed, *"^ "'•"' and the air ill the vellcl was dirainifiicd by about jth of its volume. In this flate ir did nor precipitate lime water; but inftantly cxiingiiillicrodoced, about as much dcphlogiflicaled air vas obtEincd as liad been left by the common lir in the calcination ; and by re- combining tl'.is with the iiuxious air left in the vcflel, hereconipoftd a fluid nearly of the lame goodncfs with common air.

Notwith- Jtanding the heat of the animal, which neccUitrily, it trll, rariiicd tiieair in the receiver, there was a fen- iiiile dimi.iution of its bulk ; which, at the end of 15 minutes, amounted to one-fortieth : but, inlltad of incrcafing afterwards, the diminution bc.amc Ibmc- ih ing lets in about half an hour ; and u lieu the animal was dead, and the air in the reccivcrhad recovered the temperature of the room wlicie the experiment was made, the diminution did not a])pear to exceed oiie- li:itcenthpart. — I'liisair which had been refpircd by the fparrow, though in many refpcctsiiinilar to that in which the mercury had been calcined, uiifcrcd from it in this refpecl, that it precipitated lime-water, and, by introducing cauilic lixed alkali to ii, was reduced one-lixth in bulk by the abforption of hxed air ; after w hich it appeared cxadly the fame with that produced by the calcination of mercury or other metals ; and at- mofphcrical air wab recompofed by mixing this with pure dcphlogiilicatcd air in the proportions already mentioned. That common air is compounded uf two kinds of elallie Huids, Mr Scheele has proved by the following experiment.: " I diffblved ( fays he ) one ounce of al- kaline liverof fulphur iueightounces of water ; of this folution I poured four ounces into an empty bottle, whofc capacity was 24 ounces, and worked it well ; then I turned the bottle, immerfed its neck intoafmall veilcl with water, and kept it in this pofition a fort- night. The folutior>had partly loft its red colour, and lonie fulphuf liad been precipitated fromit during this time. After this 1 put the bottle in the fame poiition in a larger velfel with water, keeping the mouth and neck under water, and the bottom of the bottle above water, and thus I drew the cork under water, which immediately rulhed W'iih violence into the bottle. On examining the quantify of water in the bottle, it was found, that during this fortnight, fix parts out of 20 of air were loft." On repcatins>; the experiment w'ith the fame matcriils, and in the fame bottle, only four parts out of 20 were loll by llanding a week, and no more than lix after four months. From thefe experiments, and many others fimilar, it appears that the do,.-lrine of phlogillon had been car- ried too far by Dr Pricllley and other Britidi philofo- phcrs,and that the air confifts of two kinds of fluids ; 'one perfectly falutary, and friendly in the higheft de- gree to animal life ; the other altogether untit for it. Thefe two appear incapable of being converted direct- ly into one another by any proccfs, natural or arti.'ici- al : for though both are dcftruftiblc, yet they arc always converted into other fubftances ; from which LOGY.

About three ounce-meafjres of air, vioustoair, phlogiflicatcd by nitrous air, was agitated for a quar- and purifies ter of an hour in a vcllel containing 20 ounces of wa- '' '" r^'fl'"? ter, which had been boiled forfcveral hours, and which '•^'■""g''- was Hill very warm. By this proccls it became dimi- nilhcd one-lixth, and conliderably improved in qua- lily. The next day the remainder was agitated for another quarter of an hour, and the water which had been boiled at the fame time, when it was alfo diminifhed in quantity and improved in quality. 2. An equal qua;uity of air, phlogiHicated by means ot iron-filings and brimllonc, being agitated for 20 miiuites, was diminilhcil one fevcutli^ andimproved fo far that a candle would burn in it. 3. After ex- pelling all the air he could from a quantity of water by boiling, he put to it, in feparate phials, air that had been phlogiHicated with iron-tilingsandbrimHonc, as well as that which the heat had expelled, leaving them with their moiuhs in water, and agitating them occalionally. On examining the phials in about two mouths, he found both the air that was confined by water and that which had been expelled by heat com- pleiely phlogiilicatcd. 4. That water does imbibe the purer partof the atmofphcre.inpreference to that which is impure, is evident, he fays, from any examination of it : For if the water be clear, and free from any thing that is putrcfccnt, the air expelled from it by heat is ge- nerally of the llandard of i ; whereas that of the atmo- fphere, when the nitrousair isthc purell. is about 1.2.

Mr Kirwan, in the 711! volume of the I'hilofophical Traafaclions, gives anaccount of hi&ingcnious method of finding the fpccitlc gravity of fixed air in its tixcd ' flate, when combined with calcareous earth, from which it appears, that fixed air, in tliat Itate, ispro- digioully concentrated, and, were it polfible to cxifl by itfclf in that concentrated (late, it would be the heaviefi; body known, geld and platina excepted. MrKirwan firftafcertained thefpccilic gravity of a piece of white marble ; then expelled the fixed air from a known weight of it liuely powdered, by means of di- lute^ vitriolic acid; the bulk and weight of the obtain- ed fixed air being afcertained. Next, he calcined a known quantity of the fame fort of marble, by keeping it in a whire heat for the fpace of 14 hours ; after which, being weighed again, and from the weight loit by this calcination, the weight of the fixed air, which mull have efcaped ("rora it according to the abovemen- tioned experiment, being fubtraCted, the remainder is the weight of water contained in tlie marble; from which experiments it appears, that too grains of the marble contained 32.42grainsof fixed air, 11.66 grains of water, and JJ.92 grains of pure calcareous earth. << I next (fays he) proceeded todifcover the fpccific gravity of the lime. Intoa brafsbox, which weighed 607.65 grains, and in the bottom of which a fmall hole was drilled, I fluffed as much as polhble of the finely- powdered lime, and then fcrewcd the cover on, and weighed it both in air and in water. When immerfcd in this latter, a confiderablc quantity of common air was expelled ; when this ceafcd, I weighed it. The refult of this experiment was as follows: Grains. Weight of the box in air - - 607.6J Its lofs of weight in water - - 73-75 Weight of the box and lime in air - 1045.5 Weight of the lime lingly in air - 43>.S5 Lofs of weight of the box and lime in water 256. j Lofs of weight of the lime fingly - 182.3 " Hence, dividing the abfolute weight of the lime by its lofs in water, its fpecific gravity was found to be 2.390S.

It has aconfidcrablc antifcptic power, and will even check the putrefaclion of animal fubflanccs ; iho' it has been obfervcd, th.it in this cafe it acls only by abforbing the putrid effluvia already emitted from the body, and be- comes itfeli' very offcnfive, while it fwectens the other. When taken into the lungs, it is equally poifonous with phlogiflicated orany other noxiousair,aud cxtinguiflies flame as effectually ; but, when mixed with dephlogif- licated Jiir, may be infpircd without any danger, and f ven in its pure rtatc may be fwallowed in large quan- tities, not only without danger, but with the moft filu- lary cffeds in fomc difeal'es, whence it has now be- come an article of the Materia Medica.

Conftituciit The origin of this acid was for a long time as much principles unknown as that of the others; and while the general of fixed air. prejudice remained tliat acids were a kind of primary elements unchangeable in their nature, it was fuppofed that iixcd air was fomc modification ol the others, pio. bably the nitrous. Rut the difcoverics made of late years, have abundantly tliown, that tlie chctiiical prin- ciples arc by no means fo indellrut^ible as they were imagined ; .ind that the vegetable acids particularly, may be almoll totally rcfolvcd into lixed air. Hence ic was naturally fuggclled, that fixed air itfelf might be a compound of fome other principles ; and it was fiiggeflcd by Dr Black, that it was a combination of atmofj.herical air with jihlogifton. As the air of our atmofphcre, however, is compounded of two fubfiances, one of which naturally contains no phlogiilon, and the other as much as it can hold ; it fcenied unlikely that there (lunildbe any pollibiliiy of adding to the quat'.tity of phlogillion contained in aportionof the atmofpherc, without decompolingit in fouie manner or other. Sjc- ceeding cxi'criinenis evinced, that it was by a dccom- pofition of the pure part of atmofpherical air, and a combination ofthe phlogifton of the fuel with its bafis, that fixed air was produced ; and this iact was evinced by numerous experiments made by Mr Kirwau, Mr Lavoilicr, and i)r Pricftlcy, (j that it is now looked upon to be generally elUbliihcd: and as the cxperi meats made by Dr Pricllley ap]>car fully as eoiivificiiig as Fixed Air. any, we Ihall here content ourfelves with giving an ^ — " ' account of them. I'he compound nature of iixtd air, and the principles d^ Pricft- from which it is formed, were firll difcovcrcd by Mr ley's cxpc- Kirwan ; but Dr I'rieflley was not convinced by the rimuit* on proofs he adduced, till after making fome experiments ''^f compo- of his own. The firll was, by tiring fliavings of iron^"'"" ".' in dephlogidicated air ; \\ hen he obfervcd a conlidcr- ^'^' al)le reliduum of fixed air, though that in the receiver had been of the purefl dcphlogillicated kind, and iron could only have yielded inHan;niable air. The hypo- thclis of Mr Kirwan was lUU further confirmed by an cxperi incnt in which iron- tilings, wliich could only have yielded iullammable air, were mixed with red precipi- tate, which is known to yield only purr dcphlogilli- cated air. On heating thefe in a glafs retort, tliey gave a great quantity ot fixed air, in fome portions of which ninetecn-twenticths were abforbed by lime- water, and the reliJuum was inflammable ; but when the red precipitate was mixed with powdered charcoal, which iiad been found to yield only inflammable air, the fixed air produced from it was fo pure that only one-fortieth part remained unabforbed by water, which is as pure as that generally prepared frofu chalk and oil of vitriol. In fome of thefe experiments it appeared, tliat three ouncc-meafures of dephlogifticatedair went to the compolition of two of fixed air : for one ounce of red presipitate gave 60 ounce-meafurcs of dcphlo- gillicated air ; and, when mixed with two ounces of iron-filings, it gave about 40 ounce-meafurcs of fixed air that were actually abforbed by water, belidesa rc- liduum that was inflammable. The fame proportion was obtained \\ hen half the quantity of materials were made ufe of ; but on uling an ounce of each, only 20 ouncc-meafures of fixed air, including the reliduum, could be got. Inconlideringthis fubjeCl farther, itoccurred to Dr Prieflley, that his experiments, in which charcoal was ufed, lay open to an objection, that lincc dry wood, and iniperfcclly made eh.-ircoal, yield fixed air, it might be faid, that all the elements of fixed air are contained in charcoal ; and though this fubllance alone, even with the afnUance of water, w ill not yield fixed air, this might be effccled by trealitig it with other fubilances without their imparting any thing to it ; efpecially as the inflammable air procured from charcoal by tneans of water, appears to contain fixed air when decompof- ed v.ith the dephlogiflicated kind. In order to expel all the fixed air from charcoal, he made a quantity of it from dry oak, and pounding it while Jiot, inllantly mixed four meafures of it with one of red precipitate, and, putting them into an earthen retort, got, with a heat no greater than what was futhcient to revive the mercury, a large qiantity of air, half of whicii was fixed. Afterwards the proportion of fixed air was Icfs, and at lafl no fixed air at all was obtained : but as the reliduum wasworfe than tlicconimon atmofphere,heis thence inclined tobclieve, notwith (landing MrCavcn- dilh's experiments, that pMogifliratcd air may be com- pofcd of phlogiflon and dephlogiflicated air. In ano- ther experiment he found a better proportion of char- j(,„^^rniiig coal and red precipi;ate. This was by mixing one thccumpo- ouuce of precipitate with the fame quantity of perfect fition of char- phlogillica- icd uir. Ill Prlcftlty's opli ion Sea. V.

Havi'ij; recoUecled, that in fonie former experi- ments he had obtained fixed air from nitrous acid arid charcoal, he therefore repeated the experiment wi;]i fi)nicof the fame charcoal which had then been made I ';of; when fixed air was obtained, in the quantity foinetimes only of one-fifth, and fomctin-.es of one- half; to the formation of which he fuppofed the phln- gilHcated air produced by heating the nitrous acid mufl have contributed. Cn account of the objcdions, how- ever, which might be made to the ufe of charcoal, he r.ext employed /r6//, which was liable tonothingof this kind ; and on mixing an ounce of iron-filings with as much charcoal, and then heating them in a glafs re- tort, he obtained 20 ounce-meaf'ires of air, ofwhicii onc-feventh rcu'.ained iniabforbed by water. The refi- duum was of the flandard of i .52, but fiightly inliam- mablc. Repeating tlie experiment with h.ilfan ounce of iron filings, he got 26 oun cc-mcafures of air, of which t he firfl part was pretty pure, but afterwards one- tenth remained unabforbcdby water; but on mixingonc ounce of precipitate with two ounces of filings, he got about 40 ouncc-meafurcsof air, ofthcfirlt portions of which only one-twentieth was nnabforbcd by water, though towards the conclufion the rciiduum was grea- ter. Ill this procefs he got in all 36 ounce-meafures of pure fixed air, completely abforbed by water, belldes about other four ounce-meafures, which, he fuppofcs, juight have been abforbed in receiving the air and transferring it into other velFtls. Fixed air was alfo produced from red pccipitate mixed withbrafs filings, with zinc, from turijitli mi- neral with iron filings, and from the blaclt powder into which mercury mixed with lead is cadly converted. In this lal^ cafe the Doftor fuppofcs that the fixed air was produced from the dephlogifticated kind abforbed by the metals and the plilogillon of the lead ; and this is confirmed by an obfcrvation that the fixed air always comes firftin the procefs, when the phlogiflon is mofl readily leparated, but afterwards tlie produce becomes quite pure and dcphlogiflicated. In attempting, how- ever, to increai'c the quantity of fixed air by heating this bhck powder in deplilogiflicatcdair, lie found on- ly an augmentation of the quantity of dcphlogiflicated air, anil tliatof the purefl kind. "Perhaps," fays lie, " as deciiWe aproof as any of tlie real produdion of fixed air from phlogiflon and de- f hlogiflicatcdair, may be drawn from the experiments in which I always found a quantity of it when 1 burn- ed Atlphur in dcphlogiflicated air. In one of thefc ex- periments, to which I g^ve particular attention, fix ounce-meafures and an halfof the dephlogiiiicated air were reduced to about two ounce-meafarcs ; and one- fifth of this was fixed air. When both the vitriolic acid and fixed air produced by this operation were abforbed by water, the remainder was very puredc- logiflicatcd air. " I had always concluded, that no fixed air could be procured by the dccompofition of inrtammable air which had bcten produced by mineral acids, bccaufe I *\"JL. I. LOGY. ,69 had not been able to do it v, iih that which I had get FIjed A-.r. by means of vitriolic acid ; but I learned from Mr hie- — r^* ' thcric, thattliis is peculiar to luc vitriolic acid, the re- mains of which, dirfiMcd through the in.-lammdbleair, procured by ii, he conjci5iarcs,niay aftually decor:; of: the fixed air produced in the proicfs. For, as 1 1) ivc hinted before, when the inflair.miblc air is produced from iron by mcansof fpiritof fait, there is a very per- ceivable quantity of fixed air when i; is united wiiii dc- phlogiflicated air. When I dccornpofed thefc two kinds of air in equal quantities, they wtre reduced to about 0.5 of a meafurc, and of this not more than a- bout one fortieth part was fixed air. This experiment ought, hov. ever, to be added to the other proofs of fixed air being pruduccd by the union of dephlogiUi- catcd air and phlogiflon. j,- " Thelafl iullance, which I (hall mention, of the I'roportioa generation of fixed air from phlogiflon and dephioTii". cf fixed air ticated air, is of annich more flriking nature than any r'''"J"ol th.-;t I have yet recited Having m.ade what I call "^'.T !!f.' charcoal oj coffer, by palling the vapour of fpirit of [^^ ^^ wine over copper when it was red-hot, I heated apiece of it in different kinds of air. In common air, obfer- ving neither iiicrcafe nordecrcafc in the quantity, I concluded, perhaps too haflily, that no change was made in it : for when I repeated the experiment in dephlogillicatedair, the charcoal burned very intenfc- ly ; and \\hen a part of it was confumed, wliich (like common charcoal in the fame jiroccfs, was done with- out Icavingany fenlible re(idu-.im) 1 foundthat no heat which I could apply afterwards, had any farther cffcft on what was left of the charcoal. Concludirg, there- fore, that fome change mufl be made in the quality of the air, I examined it, and found about nine-tentlis to be the purefl fixed air; and therefiduum was fach as would have been made by feparating the abfolutcly pure part of the dephlogiAicated air; leaving all the impuri- ties behind — Having afccrtaincd this facl, I repeated the experiment, weighing the piece of charcoal very carefully before and after the procefs ; and then found, that by she lofs of one grain of charcoal, I reduced four ounce meafurcsofdcphlogifticatedairtill one-ninth on- ly remained unabforbed by water ; and ag."in, with the lofs of one grain and an half of the charcoal, I reduced fix and .in half-meafures of dcphlogiflicated air till five and an Iialf-mcafures were pure fixed air. In this pro- cefs there was a diminution of bulk after thecxperi- Tncnt,as might have been expefted from the change of the air into one of a litavirr kind by means of a iiib- flancc or principle that could not add much to tlic weight of it. In one of the experiments, 4.;! ounce- meafures of deplilogiflicated air were reduced about one-thirtieth part ofthe whole ; andin this cafe, when tlie fixed air was fcparated by water, there was a rcfi- duuni of 0.7J of a meifurc ofthe flandard of r.o, whereas tlie dephlogiflicatrd air, before the experi- ment, had been of the flandard of 0.2. " That dcphlogiiiicatedair aAualiy enters into the compofition ofthe rixed air, in this experiment, is evi- dent from the weight ofthe iaff r, v. hich far exceeds that ofthe charcoal difperfed in the procefs. Fcr, in this kfl expcrimciii, the weight ofthe fixed air pro- duced was 4.95 grains. Confrq-iently, foppodng the charcoal to be wholly phlogi Hon, as itis very nearly fo, fixed air juav be faiii toconfift of 3.45 parts of dephlo- V gillicated "3 Effifts of AERO j;iAicalcil r.ir, and 1.5 of j.hldgiflon ; fo that the dc- phlogiilicatcd air is more than three times the proi)or- tio:i of jijilogillon in it I nnill not concUidc, how- ever, without oblcrving, that, in one experiment, I ne- ver tailed to produce hxed air ; thougli it is not eal'y 10 fee how onu of its fuppofcd tkinents, viz. dcphlogilli- catcd air, could enter into it. This is by heating iron in vitriolic acid air. In one of thefe experiments, four ounce-mcafuresofthcviiriolicacid air were reduced to 0.65 of an ounce-iueafure ; and of the quantity lolt three and an half meafures were fixed air abforbed by lime-water, and the remainder weal.ly inriammablc." Fixed air, even when pure and unmixed, is reniark- thc c\t&iic aijiy altered by the elearic fp.irk, part of it being thus fpark on rendered immifciblc in water. Ur Pricllley, having fixed air, j.jj.j,„ ,|,,. tic^iiic fpark for about two hours in a fmall quantity of fixed air confined by mercury, found, that after tlic cipcration,one.fourihof it remaincdlmniifti- blc with water ; though, before it, only one-thirtieth part had remained unabforbed. Theiulide of ihe tube had become very black ; wiiieh, in other experiments of 2 fimilar kind with vitriolic acid air, he had obfervcd to arife from the adlielion of a fmall quantity of mer- cury fupcrfaturated with phlogillon. In another ex- periment, in which the fpark was taken an hour and ten minutes in about half an ounce-meafure of fixed air, one-tifth remained unabforbed, and the llandardof the reliduumwaso.9;though, before theoperation, only one thirtieth part had been abforbed, and the llandard of the reliduum was i.o. Iniiii* experiment, alfb, he obfcrved, that the air was incrcafcd about a twentieth part. On taking the eleftric fpark an hour in half an ounce of fixed air, as much reliduum was left as had remained in five times the quantity of the fame fixed air in which no fpark had been taken. This rcfiduum was alio much purer than that of the original fixed air, the ftandard being 0.8 ; whereas that of the original fixed air had been, as before, i .0. On repeating the experiment, he found the refiduum flill greater, but equally pnre ; and, in this cafe, a goud quantity of black matter was obferved adhering to the tube. Ha- ving taken the fpark in a fmall tube containing ,'- th of an ounce-meafure of fixed air, the infide of the tube J, 4 was clouded with black matter, and in the bottom was Ixpcri- a fmall quantity of yellowifh matter refemblin;; ful- Bieiit in fa- phur ; the reliduum was between one-founh and one- vourot _ fifth of the whole, and Icfs pnre than formerly. This Vricftley's circumflance he alfo fuppofes to be a proof that cJnctrnin- ^'^^'^ *'"■ '"*y '^^ compofed of phlogifton and de- tfic cumi-o'- phlogillicated air. Purfuing this experiment, by ta- fition of king the cleftric fpark three hours in a fmall quantity phlogiaica- of fixed air, he obfcrved that it was firA increafcd, and ttd air. t],e;, diminiflicd about one-eighth of the whole ; the infide of the tube being very black on the upper part, and below the mercury very yellow, for the fpace of a quarter of an inch all round the tube ; but this fpace had been above the mercury in the beginning of the operation. One-third of the air remained unabforbed by water ; but fo impure, that the fiandard of it was 1.8, or alnioft completely phlogifticated — Varying the procefs by ufnig water impregnated with fixed air inftead of mercury, the quantity of air was much aug- mented by that W'hich came from the water ; but thus the far greater part of it was incapable of being ab- forbed by lime-water ; and on this occafion he obfer- o Y.

On uiil varyi ig the circumdances of the experiment, by ufing common water inllead of that which had abforDed fixed air, he found that the quality of the reliduum was evidently better than that of the original fixed air. 115 In order to difcovcr whetherthc heat or light of Ifftdtsof thceleclrie Ipark were the circumftances which ell'ett- » ftronj cd the change, the Doitor threw a flrong light, by h^'*'"" £*- means of a lens, for f'omc hours, on a quantity of ^ pounded glafs confined in fome fixed air ; but though the volume of refiduum was thus fomewhat increaled, yet as it was of the faiuc q lality with common air he fufpected that it might be only that portion which had been introduced among the particlcsof the glafs. The quantity of air was increafed after the operation. With glafs-houfe fand made very hot, the quantity of air was likewife increafed ; but the experiment was not more fatisfacliry than the former. Heated bits of cruciblesincreafed the quantity of rciiduum in thepro- portion of 10 to 6.6 ; but the quality was injured ci- ther direclly by a comparifon with nitrous air or b/ producing a larger quantity of refiduum equally bad. By heating iron, how ever, in fixed air, part of it was evidently converted into phlogillicated air. On htat- ing turnings of malleable iron for fome time in fixed air, one-tenth partof it was rendered immifcible with water ; and on rcpeatirig the procefs with the remain- der, there was a refiduum of one-fourth of the whole. There was alfo a fmall addiiion to the quantity of air after the i\rl\ part of the procefs, but none after the fecond ; nor could he, after a third and fourth pro- cefs, render more than one -fourth immifcible with wa- ter. In two experiments, the reliduum was inflam- mable, and burned with a blue Hame. ^ , With regard to the quantity of fixed air which may Ouantityof be expelled from different fubflances, Dr Prietlley ob- fijcdairex- fcrves, that from fevcn ounces of whiting, thepureft pelledfrom calcareous fubdancewe arc acquainted with, he expel- different led by heat 650 ounee-meafures of air ; by which '^"''''*""'" means the whiting was reduced to four ounces. One third of this was fomewhat phlogillicated ; the fiand- ard being 1.36 and 1.58. Repeating the exj'eriment, he obtained 440ounce-meafurcs of air from fix ounces of whiting; about one-half of which was fixed air, and the remainderof the fiandard of 1.4. On nioiflening fome calcined whitingwithwaterimpregnated with vi- triolic acid air, he obtained 90 ounce-meafures ; of which the firft portions were three-fourtlis fixed air, and the fiandard of the reliduum i.jjthe htterhadlefs fixedair.andtheflandardofthereliduum was 1.44. 'I'he whiting was rendered blackand hard, bntbccame foft and white with fpirit of fait. Three ounces and a quarter of lime fallen in the air, yielded 375 ounce- meafures ; of which about one-fifth was fixed air, and the llandard of the reliduum 1.4. Four ounces of white lead had yielded 240 meafures of air when the retort melted. The rciiduum of the firll procefs was one- third, the fiandard 1.36 ; and of the lafl the fiandard was 1. 28, that with the common atmofphere being 1.23. Two ounces and three quarters of wood-a(hes yielded, in a very flrong heat, 4'o ounce-meafures of air jofthefirft portion of which one-tenth, of the fe- cond one-third, and of the third cne-half, was fixed air Sea.

It cxtinguilhcd a candle ; fo that the air came properly fron) thealhcs, and not from any remaining; particles of the charcoal mixed with them. After theprocefs, the alhcs weigh- ed 839 grains ; but by expofiirc to the air for one day, tlic weight Wis iucrcafed to S42 grains ; and, perhaps with more heat than before, y ielued 50 ounce-mcafures of air ; of which about onc-cigluh was fixed air, and the flaudard of the reuduam 1.38 and 1.41. A can- dle burned in this reliduum, and the alhes were redu- ced to 739; grains. Two ouncc-meafures of Hom- berg's pyrophorus burned in the open air, and then diflilled in a retort, yielded 144 ouncc-meafarcs of air; of whichone-iulf at firit was fixed air, but at the lall very little. The refiduum of the firit portion cx- tinguiflied a candle, but that of the lad burned with a blue lambent liame. The flandards of both with ni- trous air were about i.8. The pyrophorus was then kept two days in the retort, with the mouth immerfed in mercury ; after which, on being taken out, it burn- ed as flrong as ever. Immediately before the burning, it weighed 428 grains ; immediately after it, 449 ; but being fpread thin and expofed to the atmofplierc for a night, the weight was incrcafed to 828 grains ; though, on being well dried, it was again reduced to 486. Subje(^ting it to a greater heat than before, the matter yielded no ounce-meafures of air ; the tirft portions of which were half lixed air, but thelaft con- tained very little, and burned with a blue lambent flame. It was then reduced to 396 grains. The ex- periment was then repeated with a quantity of pyro- phorus, which would not take lire in the open air ; and on heating thisfubrtance inan earthen retort, rivc- fcvenths of the firll part of the produce was tixcd air : but this proportion gradually diminiflied ; till at laft nine-tenths of the whole was inflammable air, burning with a lambent blue Jiame. This inflammable air be- ing decompofed with an equal quantity of dephlogi/li- cated air, yielded 0.86 of a meafure of lixed air. A- nother quantity of pyrophorus, which burned very well, and which by expofure to the atniofphere had gained 132 grains, being again expofed to heat in an earthen retort, gave rSoounce-mcafuresof air ; thrce-fevenths of the flrfl portion of which was lixed, and the rcll phlogillicated air ; but afterwards only one-half was fixed and the reft inflammable, burning with a lambent blue flame ; and at laft it was wholly inflammable. This pyrophorus took lire again after being poured out of the retort, but not without the alTiftance of ex- icrnal heat. It had been red-hot through the whole mafs at the firfl burning, and the furfacc was covered with white adics ; but all the inlide was as black as Cirerithid been. Kour ounces of dry ox-b!ood yield- ed I2C0 ounce-mcafures of air, and it was coHJectured that not lefs tlun 20omeafures had efcaped. It con- tained no lixed air. The flrft portii :i burned with a large lambent white liame, the middle portion f.iinter, and the laft was liardly inflammable at all. The re- maining coal weio;hcd 255 grains, and was a good con- duftor of electricity. Sect. VI. Irfiainwai/i Air. We owe the knowledge of the txiftence, and of fome remarkable properties, oftbisiir, 10 MrCavendilh, by LOG Y. 171 whom they were tir(! pnbl'r.ud in 17^7. Its c!Fc.'"!s, Ii.il-nm.s- however, had long befure been fatally expcrieliceJ by "is -•'-^- ininers ; in whofc fubterraneous habitations it is often ' collected ill fuch quantities as to produce llie moft ino'mma dreadful eficcts. It is produced in abuadancc from bU air pr.i- putrid animal a'nd vegetable fubftances ; aiid, in gene- daced iu ral, by all thole which part with tlitir phlogiftoa ca- n>iiie«rr..i« lily. Being much lighter than common air, it always P""'"' *** riics to the top of thofc places where it is generated ; '"'" *" fo that it cannot be confined except in fome vajltcd place, but always ftrives to afcend and n.ix with the atmofpherc. By itfelt it is very noxious,|and will in- ftantly put an end to animal life ; but when mixed with atmofpherical air, may be breathed in much greater quantity than fixed air. Its great inflamma- bility in th:s Hate, however, renders it very dangerous to bring any lights, or even to ftrikc a flint with ftcel, ill thofe places where it abounds. But this only takes jilace when the inflammable air is mixed with common atmofpherical or with dephlogifticated air ; in which cafe, the explolion is mudi more violent than the for- mer ; for pure inflammable air extinguilhes flame as ericctnally as fixed or phlogifticated air. Befides the fubterraneous phccsalreadymentioncd, this kind of air is found in ditches i over tiie furfacc of putrid waters, oat of which it efcapes ; in buryir.g- placcs ; in houfcs of office w here putrid animal and vege- table matters are accumulated ; and may, by Handing or boiling, be extradcd from the waters of moft lakes aiid rivers, cfpecially thofc in which great quantiticS" of fermenting and putrefying matters are thrown : and as putrefaction thus fceins to be the principal fourcc of inflammable air, it thence happens, that much more „g of it is produced in warm than in cold climates. In Great thofe countries, we are informed by Dr Franklin, that quantitlci if the mud at the Iwttom of a pond be well ftirrcJ, and produced a lighted candle brought near to the furface of the wa- '" ^' ' '''" ter immediately after, a flame will inftantly fpread a """*■ conliderable way over the water, from the accclSon of the inflammable air, affl)rding a very curious fpei-^aclc in thcnighttime. In colder climates, the generation of inflammable air is not fo plentiful as to produce this phenomenon ; ncverthclefsJ\IrCavalloinformsus,thac it may be plentifully procured in the following manner, j, in all the ponds about London. " Fill a wide-mouthed Mr Ca'aU bottle with the water of the pond, and keep it invert- iVsmtthoi cd therein; then, with a ftick, ftir the mud at the"fc"ll«<- bottora of the pond, juft under the inverted bottle, fo '"? '"fl^in- as to let the bubbles of air which come out of it enter f'"'' ""; into the bottle ; which air is inflammable. When by '"""P""'^'- thus ftirring the mud in various places, and catching the air in the bottle until this is filled, a cork or glafs floppcr nuift be put over it whilft l^anding in water ; and then the bottle may be taken homcj^in order to examine the contained inflammable fluid at leifurc." The 2;re..t quantity of inflammable air produced in \fc'(.or» warm climates has given occafion to fome philofophers thi^ught t« to fuppofe, that it may poflihiy have fome Jhare in proceed producing certain atmofpherical meteors. The weak fft"" ■'• lightnings without any explolion, which are fome- timcs perceived near the hori/.on in fercue weather, are by them co::ieClured to proceed from inflammable' air fired by eleciric cxploiions in the atmofnlxre.

In other rcfpccis, the ditfcrences between them are very conli- dcrablc.

Th'is a drop of ether, pji inii) a quan- tity of coiBnion air, mixes itfclf with it, and takes lire on the approach of flame, like a mixture of intlamnia- blc and common air j Li.i if the air to which ether is added be walhed in water, the latter is foon fcpar.ited from it. Common air becomes ajf') iuflammablc by being tranfr.iiited through f veral tilential oils ; and thus the air contiguous to the plant called \rux\milla becomes inflammable in calm and hot weather, by the emiinon of its inflammable air, liy heat alone, a conlidcrablc quantity of thi% kind of air may be extrailcd from moll inilaninuble fub- flances, and even from fome of the met lis. Dr Hales obtained inflammable air by limply diililling wax, pitch, amber, coals, peafc, and cylter flulls ; and Mr Fontana informs us, that he obtained a conlidcrab'e quantity of inflammable air from fpathofe iron, by the action of fire only applied to it in a matrafs. Dr PrieP.ley, however obtained it from a vaft number of other fubllances, by diililling them in a gun-barrel ; to the extremity of which was luted a tobacco pipe, or fmall glafs tube, with a flaccid bladder tied on the end. He obferves, that the heat mull bf fuddcnly applied, in order to get a conliJerablc quantity of air from thefe fub/lances. «' Notwithllniiding (fays hr) the fame care be taken in luting, and in every other refpecl, fix, or even ten, times n:ore air may be got by a fudden heat than by a (low one, thongli the licat that is lad applied be as inienfe as that which was ap- plied fuddcnly. A bit of dry o:'.k, weighing about ivvclve grains, will generally yiti.ta flie: p's bladder full of inrlammable air with a briik heat, when it will orily yield two or three ouncc-meafurcs if the fame heat be applied gradually." When he wanted to ex- tract inflammable air from metals, a glafs was ufcd, the focus of which aiforded a more intenfe heat than ar.y furnace he could apply : and in this w.iy he obtained inflammable air from fcveral metals ; as iron, brafs, and tin ; but with the metallic calces he had no fuc- cefs. In the infancy of his experiments, and even after very couliJcrable praiflicc, the Doctor itnaj"'^^; ih''t the infianimable air produced in this way cai.ic only InJlamnu- from the mct.il, without attending to the fliarc which ble Air. water had in the production. Some l.itc experiments ' p.'T ' of Mr Lavuilier, howcvir, U.owcd, tliat water had a Howiiro- grcat fliare in the production of iiiflammaMc air , inlo- cured from much that it gave occalion lo a fupp( lition, that the water and wutcrwas the only fourcelrom whence it was derived, "tl'cr fluid This millakc, however, was dete cd by iJr I'ritliley ; ""''/"''d lltlltlillCCft who, by his nun-.crous awA accurate experiments, leems in a manner to have exhaulied the iiityttt. Tiic me- thod which Mr Lavoilitr had followed, s\asto feml the lleam of boiling water through a red-hot iron tube; in doing which, the intenfe heat acquired by the water oeealioncd the production of a great quan- tity of iuflammable air. Dr PritlUcy repeated his ex- perimct;ts not only with water, but with other fluids. Sending the vapour of two ounces of fj^irit of wine through a red-hot earthen tube, he obt^iiiied 1900 ouncenKafuresof in flammable air, which burned v iih a white lambent flame. It contained no (ixcd air ; and 30 ounce-meafures of it weiglicd eight graias Icf.? than an equal quantity of common air. He colkaed ylfoo.jjof an ounce-mcafurc of water. In thistxpcri- nicnt,thc weight of the water eolletttd wcs 1 63 grains, of the inflammable air 633 grains, and tlutof the fpirit of wine originally was 821 grains, {ii that as little was loft in the procefsas could beexpccled. — Repeating the experiment with vitriolic ether, an ounce of it treated in the fame manner in an earthen tube almoft fllled with pieces of broken earthen retorts and crucibles, one-tenth part of an ounce of water was collcilied, and 7<}Oouuce-ineafures of inflamsnable air were pro- cured, without any mixture of lixcd air, burning witli a white lambent flame like that of wood, anj not exploding with dcpiilogillicated air. Tweiuy- ninc ounce-nieafurcs of this w eighed five grains Icfs than an equal quantity of common air. Vapour of fpirit of turpentine yielded inflammable air mixed with much black fmoke, which foon collected on the fur- face of the water in the receiver. The fnull of this air w.is ixceedingly olfenlivc, and its flame was nnich lef? biniinous than that of the former. Its fpecific gravity was the fame with that of the air procured from fpirit of wine. Oiive oil yielded a conlidcrable quantity of airon beingmixed with calcined whiting ; thefirlt portions burning with a Urge white flame, and the lalt with a lambent blue one. In cxtrading air from folid fubftances, the fleam of water was always necellary ; and tlius inflammable air was produced from a great number of ditt<:rent ones. From fulplutr treated in this manner in an earthen tube, inflammable air was obtained of a nature fiir.ilar to that from oil of vitriol and iron. From ar- fcnic, the produce was onc-fevci:tii of fixed air ; but all the reft ilrongly inflammable, with a fmcll fcarccly Ciftinguifhable from th.it of phofphorus. Twenty ouncc-meafurcs of this air weighed 4, grains lefs than an equal quantity of common air. Both thefe experi- ments, however, were very iroublefoine, on account of the volatility of the matters, which fublinieil and choakcd up the tubes. From two ounces of the fealcs of iron or fining cinder, which he has found to be the fame thing, Dr Prietlley obtained jfio ouncc- mcafures of air; one-tenth of the nrfi part of whicfi was f.::cd air, but afterwards it was all iniiammablc.

Under this jar the inrfammable air burn- ed as long as it could; and when extinguilhed for want of more pure air, 1 fulfcrcd the liquor to rife as high as it could within the jar, that it might imbibe whatever fhould be depoiitcd from the decompofition of either of the two kinds of air. I then took off the jar, changed the air in it, and lighting the flrcasi of inilanimablc air, replaced the jar as before. This I did till I had decompofcd a very great quantity of the two kinds uf air, without perceiving the leall change in the colour of the liquor, which mart have been the cafe if any acid had entered as a ncceflary conlbtuent part into viiher of the two kinds of air. I alfo found no acid whatever iu the water, which was procured by keeping a ftream of inflammable air con- fUntly burning in a large glafs balloon, through which the air could circulate, fo that the tiar.ie did not go out. Neither was there any acid produced in the dc- compoiition of ia:lamniablc and dcphlogilticatcd air in a ftron_^ elofe glafs velfcl. " With refpecf to indammable air, I haveobferved, that when futficicnt care is taken to free it from any acid vapour that may be accidentally contained in it, it is not iu the fmallcil degree atle.-led by a mixture of alkaline air.

Mr Cavendilh firft perceived the ncceflity of nioi- fliirc to the production of iullanimable air ; but it was not until after making fcvcral experiments that l)r PrielUey coulJ adopt ihclanie idea. He had obftrved fome very remarl^able circumllanccs relating to the production of inlianimablc air from charcoal, by which he war. induced to fuppofe thai the former was pure phlogifton in a volatile Hate without any moillurc whatever. The Doelor obfcrves, that " charcoal is generally faid to be indellrucliblc, except by a red heat in contact with air. Hut 1 lind (fays lie), that it is perfectly Jellrui5tiblc, or dccompofed, /'.' vacwi, and, by tlic heat of a burning lens, almoll convertible into inllammable air ; lb that nothing remains beildcs an exceedingly fniall quantity of white allies, which are feldom vifible, except when in very fmall particles th cy happen to crofs the fun-beains as they tiy about tlie receiver. It would be be impollible to collect or weigh them i but according to appearance, the afnes thus produced, from many pounds of wood, could not be fuppofedto weigh a grain. The great weight ofalhes produced by burning wood in open air arifes from whatisattracfted by them from the air. The air which I get in this manner is wholly inflammable, without the leaft particle of fixed air in it. But in order to this, the charcoal muft be perfectly well made, or with fuch a heat as would expel all the fixed air which the wood contains ; and it nuilt be continued till it yields inllinimable air only, which in an earthen retort, is foon produced. " Wood or charcoal is even perfedly deftruCliblc, that is, refolvable into inflammable air, in a good earthen retort, and a (ire that would about melt iron. In thcfe circuniftances, after all the fixed air had come over, I Icvcral times cor.tinued the proccfs during a whole day ; in all which time inilammablc air has been produced equably, and without any appearance of a termination. Nor did I wonder at this, after f;.eing it wholly vanifii into inflammable air;« vacuo. A quantity of charcoal made from oak, and weighing about an ounce, generally gave me about five ouncc- meafures of inflammable air in twelve minutes." Although from thcfe experiments it did not appear that water was in any waysclTcntially necelfary to the produftionofthiskindof inflammable air, it appeared manifeftly to be fo in the following : " At the time (fays he) when! difperfedanyquantityof charcoal with a burning lrns/« vacuo, and thereby filled ray receiver with nothing but inflamniablc air, I had no fufpicion that the wet leather on which my receiver llood could have any influence in the cafe, while the piece of char- coal was fubjcft to the intenfe heat of the lens, a;:d placed feveral inches above the leather. I had alio procured inflammable air from charcoal in a glazed earthen retort for tsvo whole days luccellivcly, during which it continued to yield it without intermiilion.

But my attention being now fuliy awakened to the fuljert, I prclently found that the ciremnltances abovementioned had actually milled nic; I mean with refpccl to the concluflon which I dre\r from the experiments, and not with refpcft to the ex- periments thenifclves, every one of which will, I doubt not, be found to anfwer, when properly tried. " Being thus apprifed of the inlluence of unper- ceivcd moillure in the production of intlammaLlc air, and willing to afcenaia it to my perfect faiisfaction, I began with filling a gun-barrel with iron tilings in their common flate,without taking any particular pre- caution to dry them, and I found that they gave air as they had been uled to do, and continued 10 do fo many hours : I even got ten ounce-meafures of inllam- mable air from two ounces of iron filings in a coated glafs retort : At length, however, the production of iniiammablc air from the gun-barrel ceafed ; but, on putting water to it, the air was produced again ; and j a few repetitions of the experiment convinced nic that fnflamnia- I had been too precipitate in concluding that inflam- i,leairi»ii"t mable air is pure phlogiflon. I then repeated the ex- pure phlo- periment with the charcoal, making the receiver, the ijifon. Itand on which I placed the charcoal, and the charcoal itfclf, as dry and hot as poUiblc, and uling cement in- Jlead of wet leather, in order to exclude the air. In thcfe circumflances I was not able, with the advantage of a good fun and an excellent burning lens, to dccom- pofc uIii/i f J iixcd air, and likcwife the relative quantity of phlogifton contained in each of them. The former appeared by wafliing the air with lime-water after the cxplolion, and obfcrving how much of them was abforbcd ; and the latter by examining the refiduum with the teft of nitrous air, and obfcrving the purity of it. Kinding, however, that, In fome cafes, more fixed air was found after the cxplolion than could have been contaiutdm the inflam- mable air, he was thence led tooblcrvcthe^fn!Ta//»«of fixed air from t he princplcs mentioned in thclaflfcJlion. In profecuting this fubjcct, it was found, that one nieafure of inrlammable air produced by fteam from metals, and one of ilcphlogillicated air, f ich as by mixture with two raeafures of nitrous air was reduced to 0.72 of a meafure, were reduced by explofion to 0.6 ot a meafure ; the refiduum, by an equal quantity of nitrous air, was reduced to 0.87. With the fame dcphlogillicatcd air, the inflammable air from fining- cinder and charcoal was reduced only to 1. 8 J of a meafure ; but by waQiing in lime-water, to 1.2. The rcliduura examined by nitrous air appeared to be of the flandardofo.9. In another procefs, the diminution after the cxplolion was to i. 5 j, and that after wafliing in lime- water to o.6y, of a meafure ; in a third, by explofion to 1.6, and by wafliing to 0.66 ; and in a fourth, the tirlt diminution was to 1.6, and the fecond to 0.9. In this lad experiment there was n. generation of an entire meafure of fixed air ; and that this had not been con- tained originally in any latent llate in the original fluid, was evident from the fpecific gravity of the in- flammable air made ufe of. This, indeed, was one of the heavieft kinds of the fluid : but 40 ouncc-meafures of it weighed only two grains more than an equal bulk of common air ; whereas, had all the fixed air found in the refiduum been cmitaiuei in the original air, it muft h.ive been at lealt one half heavier. " Indeed (fays the Doctor) if any quantity of inflammable air, of about the funic fpecific gravity with common air (which is the cafe with that fpecies of it 1 am now conlidcrinn;), yield fo much as feven-trnthsof its bulk of fixed air in confequence of its explofion with de- phlogifticatcd air, it is a proof that at Icafl part of that fixed air was generated in the procefs, becaufc feven-tenths of fuch fixed air would weigh more than the whole meafure of inflammable air." '75 Equal parts of dcphlogifiicated air and the inflam- Infiamn-.a- mablc kind produced from fpirit of wine, were redu- bic Air. ced to one mealure, and by wafliing in lime-water to ^""^ 0.6 of a meafure. The ftandard ot the refiduum was 1.7. — In another cxptrimcnt^ in which the vapour of the fpirit of wine had palled tiirough a tube tilled with bits of crucibles, the ririt diuiiuution was to 1.6, the fecond to 1.4, and the Itandar J of the reliduuin was to 1.84: but in a third, the firlt Jirr.iiiution was to 1.2, the fecond to 0.9. — Air procured by Iteam from red- hot platina was reduced to 0.72 of a meafure, and the ftandard of the refiduum was 0.9. It contained no fixed air. — t\\r from brimltonc, with an equal part of dcphlogifticatcd air, was diniinilhcd to 0.6, and ho fixed air was found in the refiduum. Its ftandard was 0.95 — With inflammable air from arfcnic, the nrfl re- duction was to I.I J, tlu- fecond to 0.95. The ftand- ard was 0.82 With the inflammable air procured bv adccompofition of alkali. le air, the diminution by ex- plofion was to 0.96, and no fixed air was contained in the refiduum; the ftandard of which was 0.8 — In- flammable air from ether refcmbles that from fpirit of wine. The firll diminution was to 1.36, the fecond to 1.2 ; and the ftandard was 1.9. Inflammable air procured by means of fteam from charcoal of metals produces a confidcrable quantity of fixed air ; the firll diminution being to 1.12, the fe- cond to 0.8, and the ftandard of the refiduum 1.9. This analylis was of the firft portion that came over, the fecond was fomewhat different : the firft diminu- tion being to i.o, the fecond to 0.75, and the ftand- ard of the refiduum 1.9. — From conk, or the charcoal of pitcoal.the rirfl diniiiiution was to t.15, the fecond to 0.9 J, and the ftandard 7.9; but the dephlogiflica- tcd air in this experiment was by no means pure. With inflammable air from f'pirit of turpentine, the firft diminution was to 1.7, the fecond to 1.6, and the ftandard 1.9 — From bones, the firft diminution was to 0.67, the fecond to o.j8; the ftandard 1.47 From common charcoal, the firft diminution was to 1.5, the fecond to o 74, and the ftandard 1.7. In ano- ther experiment, the firft diminution was to 0.82, the fecond to 0.63, and the ftandard of the refiduum 1.37. Inflammable air procured by diftilling fome rich mould in a gun-barrel had a ycry otfenfivc fmell, like thatprocurcd from putrid vegetables ; itcontained one- twentieth part of uncombincd fixed air. When this was fcparated from it, and the remainder decompofcd with dephlogiflicated air, the firft diminution was to 1.4, the fecund to 0.67, and the ftandard of the refi- duum was 0.6. — The air procured from caft iron has likcwife a peculiarly oflcnfive fmell ; and, on this ac- count, the Doctor imagined, that it might contain more phlogiftoii than couimon inflammable air, fo as to abforb more dephlojrifticatcd air than the other. But this conjecture did not appear to be well founded ; for on exploding it with dephlogiflicated air in the proportions inrianiniablc air cxtradcd from clean ne wly-nia>!e filinfj nd obtained over gifton, informs us, that in hiscxperimeius he uicd •• .._ ,..„>.^ ....,■.> of foft iron, in the temperifirc of 59", by vitriolic acid whofc fpecific gravity was 1.097?, and obtained over mercury, having very little fmell, and what it had being very unlike the ufu.il fmell of inrlimmab'.e .lir." The weight of this air, when the biromctcr flood at 29.9, and the tlicrmomcter at 60°, was foaud to be to that of common air as 84.3 to loooj and, confcquently, near 12 times lighter. 176 E R O L O G Scc"t.

The inrianimable air, by the fubtraetion of its water, loll its fmell, but continued as inliaramabic as ever ; and there- fore there is norcafon to think that it was decompofcd, or thjt water is any way elfential to it." The coacluiio.i is dircftly contrary to that of Dr Pricfllcy, that -water is an elfential ingredient in the compoliiion of inrtammable air ; nor do ilic experi- ments of the latter, already recited, fccm to have had any weight with him, as he concludes his Trcatife on j,g Phiogifton in thcfe words. <• lo the proofs I have Mr Kir- hcretofore given, that inllammable air and phlogillon wan's conJ are the fame fubdance, jull as ice and the vapour of c'ufinn con- water are called the f.»me fubdance, no objcLtion of '^'^'^""['C '*'* any wcii^-ht has fincc b:cn made.

Laftly, others have thought, that it clfentially requires an acid oran alkali, or fomc falinc fiibltance, for its bafis ; as if there were any more repugnance in the natureof things that phlo- girton (liould exifl in an aerial ftate without any balls, than marine air, alkaline air, or dephlogidicatcd air; when it is evident, than an aerial flate requires no more than a certain proportion of latent heat : but the pro- duction of inflammable air from iron by means of di- flilled water, without any acid or fait, has effcdlually done away any fufpicion of that fort." j,. On the other Iiand, Dr Pricllley informs us, thatprPricd- " inflammable air fccmsnowtoconiift of water and in- leys con- flammable air : which, however, feems extraordinary, cluCon. as the two fubfiances are hereby made to involve eacli other ; one of the conftituent pans of water being ir.- flammablc air, and one of the confiitutiit parts of in- flammable airbeingwater ; and therefore, if the expe- riments would favour it (but I do not fee that flicvdo io).

But it is probable that oi/, and that of dif- ferent kinds, may be held in foluiion in fevcral of them, and be the reafon of their burning with a lam- bent flame, and alfo of their being fo readily refolvtd into fixed air when they arc decompofcd by dephlo- gillicatcd air ; though why this Ihould be tlic cat'c, I cannot imagine. " When inflammable and dcphlogifticated air arc burned together, the weight of the water produced is never, I believe, found quite equal to that of both kinds of air. May not the /ig/'t, therefore, emitted from the flame, be partof the phlugillonof the iiirt.immablc air united to the principle of heat ? And as light accom- panies the clcBricfpark, may not this alfo be the real accenfim of fome phlogiflic matter, tliough it is not eafy to find the fource of it." The French chemifts, who deny the cxiftencc of phlogifton, are of opinion, that iurianiniable air is a iimplc uncompo'inded element; but lor a more full 140 difcullionof this fubject, fee tlic article Phlogiston. Abforpcion Inflammable air is abforbcd by water in ronfidcrablc ofinflam- quantity, but by the application of heat may be expel- mable air Jcjagjjn ju equal 'quantity. By agitation in water Dr Prieltky was formerly of opinion that this kind of air might be rendered as good as common air ; but this undoubtedly proceeds from the atmofpherical air tranf- mitted bythe water, as is the cafe witU pMogilUcated air mentioned in the kill fcetion. After a quantity of water, which had abforbed as much inflammable airas it could, had been futfercdto lland a month, it was ex- pelled by heat, and found to be asllrongly inflammable as ever. The water after the procefs, depofited a kind of filmy matter ; which he fuppofed to be the earth of the metal that had keen employed in produ- cing it. Plants in general grow tolerably well in inflammable on vegeta- 3]^^ j„j [],j billow plant has been obferved to abforb tioii and great q;uiuitics of it. Its inflammability is not di- minilhed by the putrefaflion of animal fubllanccs, nor does their putrefadi nfcem to be retarded byit. Ani- mals confined in it are killed almo.1 as-foon as in fixed air: but infecls, which can live a conliderable timcia phlogirticated air, live alfo a conliderable time in this kindofair; but at lafl they become torpid, and appear to be dea<', though they will ftill recover if removed into the open air. Mr Cavallo relates, that the Abbe Fontana, having filled aUrgc bladder with inflammable air, began to breathe it in hi^ prefcnec ; after having made a very violent expiration, in which cafe the ef- fects arc moft powcrfid.

When the bladder is prefled, the inflammable air, being made to pafs into, the tube, i:liics out of all the fraall apertures, and is let on Arc by a lighted taper. None of thefc contrivances, however, have ever been applied to any ufe ; and the fcheme of Mr V'olta, who propofed to fubftitutc its ex- plolive force inllead of gun-powder, is found infufli- cient, onaccount of ihe weaknefs of the cxplofion, ex- cept when the two airs arc fired in very great quan- tity, which would be incompatible with the fmall bidk neccffary for warlike engines. Sect. VII. Sulphurated JujlammabU Air. This was difcovered by Dr Prieftley at the timt when he was engaged in the experiment of which I'orac account has been given in thclallfection, of tranf'mit- ting the fleam of water and other fluids through red- - . hoi tubes containing fomefoliJ material. H3\ing, a- nrU prc- mong others, treated manganefc in this manner, by cured from flopping one end of the heated tube with a cork be- mangiuieft. fore the lleam was applied, he received forty ouacc- meafures of air, of which one fixth was fixed air, aiid the refl of the llandard of 1.7, lambeiitly iunammablc. Having then opened the other end of the tube ia or- der to admit the ftcam, air was procured more co- pioufly than before. Of 50 ounces of thli air, o.ic/. fcventh was fixed, and the reft, of thellandard of 1.8, cxjloilvcly inflammable. The lafl portions were vcr/ turbid ; and the fmell, cfpecially that of the hll por- tion, was very f ilpUurcoiis, liuging the water of a ve- ry dark colour, by drpofitingia it a quantity of blackilh water. However, thcair itfclfbccimcprefcnily tranl- « parent, and had no oiher appearance than that of any other kind of air. On looking ai the jar in about ten minutes after, it was quite black and opaque; fo that Kothi'ig could befcen in theinfidcof it. Filling after- wards another jar wiih the lame kind of air, in order to obfervc 1 he progrcfs of this uncommon p'oenome no>i, he found, that when the water was ^^■cUl'l;^;ided, black fpecks began to apptar in dificrent places, and, cx^ tending thcmfclvcs ia all directions, at length joined each other, till the whole jar w:is become perfev'tly black, and the gl ifs opaque. When this w as doiiC, he transferred the air into anoihcr jar ; and it toon pro- tUiced a liiuilarcficclui'xm this, tiiougbi; never became vjtriolic acid air. iyH A li R O inlluminar fo black as tlic jar in wliicli it had been firft rccci- i)Ie Air. ye J, Italfo rrcqucmly luipjoicd, that only the lower '■'""' part of tlic jar would become blick, as it the iiiaitcr with which it was loaded had kept fubiidiiig, tliough invilibly, in tke iiiafs of air, and occupied aiily the Jowcrrcgioiis, kavingthc upper pan entirely free from •• it. On cspoling to the open air tlic vcll'els thus turn- ed blr.ck, the colour prefcnily ilifa|'pcarcd, .ind a yel- low or brown incnillation wa;. leli upon ii. The fame change took place when the vellcls were inverted ij water, in order to.obferve the alteration of thcairwitli- in them ; but on examining this air, no fenfiblc change was perceived. In fume cafes, indeed, he thought the air wis injured, but it was mucli lefs fo than he Tfad expected. After dcpofiting the black matter, the air ftill retained its fulpluircous fmell, and he did not imagine that would ever leave it entirely. Procured On trying other fpecimcns of manganefc, no air of from ivory this kind was obtained ; bi'.t fonit time after, having melteil in occafion to make a large quantity of inriamni.ilde air, he ufcd, inllcad of frelh iron, foine that had been al- ready melted in vitriolic acid air. Dillolvinj; ihiswiih a coniidcrable quantity of frelh metal in diluted vitrio- Jic acid, he found that the water in which the air was received became very black, and depolitcd more fedi- nient than had appeared in the experiment with the manganefe. The jars were as black as ink, but be- came yellow on expofure to the air as before ; fo that there could be no doubt of its being the fame thing he had got before. On burning a quantity ot it, this kind of air appeared to contain fonie vitriolic acid, the balloon being tilled with a very denfe white fume, which rendered the water fenfibly acid to the talle. On de- compofing it w'th Jephlogifticatcd air, however, he found the dimiuution exactly the fame as when com- mon in:iamnTable and dephlogifticated air were ufcd ; fo that it appeared to contain neither more nor lefs phlo- gillon than the other ; only there was afniall quantity of lixcd air produced, which is never the cafe with common intiammable air from vitriolic acid and iron. Whcnthc fulphuratedinllammableairisrcceivcd o- ver mercujy, very little black matter is produced on the jars; and it is remarkable, that though the black tiiaticrcollcdedon theiii,when the air-is taken through water, foon grows yellow upon expofmg it to tlic air, it is not the cafe v»ith that which remains in the wa- ter; it adheres to the evaporating vell'cl in form of a black incrullation, which does not burn blue until it has been digelled in the niirousjicid, which deprives it of its fuperriuous phlogillon, aud leaves it both of the colour and fmell of fulphur. Sect. VIII. Of ^Ikalhie Air. This was procured by Dr Pricftley, in the begin- ning of his experiments, from common fpirit of fal- .inimoniacwith quicklime, or the materials from which it is made. He did not at that time profecute tl:e difcovcry fartherthan by imprcgnatingwater with it ; ky whif-li means he couhI make a much llronger alka- line fpirit than any to be met with in the (hops. His method of procuring it was by mixing one part oi poundcdfal-ammoniac with three pans of Hacked lime; and forconimoit experiments the fame quantity of ma- terials would lall a coniidcrable tiuie.

The electric (park taken in it ap- pears of a red colour. Every fpark taken in it aug- ments its bulk, and by degrees turns the whole into inriammable air. It is readily abforbcd by water, as has been already obferved, and dillolvcs ice alniofl as lalt as an hot lire. On confining (bme w atcr iiupreg- jiated with alkaline air in a glafs tube, and thus expo- fmg it to a ftronghcat in a faiid-fi:rnacc forfome days, he obferved that a white fediment or incrullation waj . formed on the fiirlacc. The Dr remarked, that bits of linen, charcoal, and fpongc, admitted into a quantity of alkaline air, diiniiiilhed it, and acquired a very pungeut fmell; cfpecially the fuonge, a bit of which, about the fiice of an hazle-nut, abfoj-bed ca ounce-meafure. It is remarkable that copper, which is fo ealily corroded by the common volatile alkalis, is not affected by alkaline air. The fpecilic gravity of this kind of air is, by Mr Kirwan, determined to be to that of common air as 600 to loco ; though, as he jullly obfervcs, this niufl differ very confidcrably ac- cording to the quantity of moidure it contains. j^j In profccutiug his experiments on alkaline air, Dr Proofs of PrieRlcy conluded that it contains phlogiflon, both its contain- from its being convertibleiiito iiillammableair by dec- ";P P'^''-'" trie explollous, and likcwUt from its reviving thecal- e'"""" ces of metals. In attempting to afcertain the quan- tity of lead revived in alkaline air he met with two dithculties ; the firff, on account of foinc part of ilic calx being blackened and imperfectly revived ; thefc- cond, that the lead completely revived wasdillblvedby the mercury employed to confine the air. To prevent this lall inconvenience, he put the powdered maflicot (tiic fubffance he chofe toemployon thisoccafion) in- to fmall cirthen cups, contriving to place them with their mouths upwards, in fuch a manner, that wlicn the lead was revived by means of a buriiing lens, it would remain in the cup, and not nii.K with the mer- cury which fupported it. The proportions of metal then revived, w ere fix grains ol lead in three ounce- meafures, 16; in three mcafures and an half, 13 in two and an half, and 1 2 in three and three-fourths ; but the experiment on w'hich he laid the greatefl llrefs, was that in which 26; grains of lead were revived in 7; ounce-meafures of alkaline air. In this proportion, 100 ounce-mcafures of alkaline air, would revive 552 grainsoflead ; butan equal quantity of intiammable air from iron would have revived 4?o grains ofmetnl. This deficiency appeared fomewhat furpriling to the Doctor, confidcring that alkaline air refolvcd into more than twice its bulk of the inflammable kind; though it is pollible, that inflammable air from iron may contain more phlogiflon than that into which al- kaline air is refolvable. On heating red precipitate in alkaline air, the mer- cury was revived as in other cafes, and a conliderable quantity of water was produced, though none appears «n .sedt.vm.

In another experiment, a violent explofion took place before he could obferve whether any water 148 ^^•'"' produced or not. Convrrfion In examining the phenomena which attend the con- of alkaline verlion of alkaline air into the inflammable kind, the iiitoinflam-Dotrlor was induced to believe that it was ocealioned niablc uir. [j^ licataloivc, without the concurrence of light. The citccls of the former were iirll perceived on heating ome ochi c of iron in alkaline air; when, though the matter turned black, as in an incipient redii.Sion of the metal, he Ibund a conliderable increafe of quantity in- llcad of decreafein the air, as he had expected ; and, on examining the quality of it, he found that it con- tained no fixed air, but was entirely inrtammablc. With fcales of iron a limilarenlargement was perceived ; but in this way he could never increafe the quantity to more than double that which had been originally employed, and even after thi,s the w hole fmelled flrongly of vola- tile alkali ; and the iron had undergone no change. The Dodor now, concluding from thefe experiments that the cliangc of alkaline into inrtammablc air was produced by this caufc alone, proceeded to repeat the experiment, by heating in the alkaline air bits of dry crucibles, or of earthen retorts, which had been jult before expofed to very great heats, fo that they could not be fuppofcd to give out any air tliemfelves, and therefore could only fervc to communicate a Ilrong heat to the alkaline air ; and in thefe experiments the rcfult was the fame as wh.cn ochre and iron were made ufe of. The bits of white earthen ware were always turned black ; but finding the fame cfFeft of augmcnt- rngthe airand giving it an inriammable quality, though lie ufed the bit of crucible over and over again, he was thoroughly convinced that the change was effecJted by heat alone. In all thefe experiments, however, with a burning- glafs, as a ftrong light was alfo concerned, he heated a quantity of alkaline air in a green glafs retort, receiving inaglafs tube, filled with water, all the air that could be expelled from it by heat. At firft it was all abforb- cd by the water, being merely alkaline air expelled by the rarefaction ; but when the bulb of the retort be- came red-hot, he found tliat the bubbles driven out were not wholly abforbed, and at tail none of them were fo Tiiefe were altogethrr intiamniable ; fotliat no doubt remained of the change being produced by heat alone, without any intervention of light. It was farther obferved, that whenever thealkaline air was changed into inliammable by means of tiits of retorts or rrncibles containing clay, they always be- came black during the procefs. He inclined therefore to fuppof*, that foinelliiug raiglit be depofitcd from the air which might attach itftlf to the clay- " In- deed, (fays he) if ihis was not the cafe, I do not Ice why tile clay ihouUI become blark ; though, perhaps, part of the fame phlogiftoii which fornij the intlam- fliablc air may be attracted by the red-hot clay, with- 79 f>u> air aud iron. out there being any proper decomporuioa of the air.

The Arong nitrous acid abforbs it in great quantity ; and becomes fmokiiig, orange co- loured, and afterwards green, on account of the phlo- gillon contained in it. Marine acid imbibes but a fmall quantity, and very llowly, acquiring at tlie fame lime a light-blue colour. Both nitrous air and com- mon air jihlogilUcated by it are meliorated by agita- tion in nitrous acid. Nitrous air is abforbed in confiderable quantity by radical vinegar, and the concentrated vegetable acid Solution of green vitriol imbibes it in much greater quantity than water, and acquires a black colour ; which, liowever, foon goes off by expofurc to the common air. Its talle alio becomes acid. — Very little is abforbed by caullic alkalis. Oil-olive flowiy ab- forbs a conlidcrable quantity, but oil of turpentine abforbs much more. By a little agitation, it will imbibe more than ten times its quantity of nitrous air ; acquiring at the fame time ayellowilh or orange colour, and becoming a little glutinous. The part which is not abforbed appears to be converted into plilogillicated air. — Ether and fpirit of wine abforb it very quickly, but no nitrons air is obtained by the apjdication of heat after they have abforbed it. .It is greatly dimini;hcd by oil of turpentine, liver of ful- phar, and pyrophorus ; all of which leave it in a phlo- gillicated Hate. It is alfo diminifiicdand phlogillica- tcd by being kept in a bladder, alternately expofctl to moillure and drynefs. Nitrous acidair has the fame efFe<5l.

Tliis property, it was thought, iiiif^ht have been extremely ufcful on many occuiions ; but Dr I'ricflUy, after a number of expcri.Ticnts on the f ibjfd coiicludesin the following manner. " Ni- trous air will indeed prcfcrvc meat from putref.i(^lion ; but after long Kccpinj;, it becomes very oifenlive Loth to tlic nolhils and palate, though the fSr.ell ii nor alto- gether that of putrefaclion ; and indeed the fubllancc toiuinuingquiLc firm, it could not be properly putrid. — Having formerly experienced the remarkable anii- kplic power of nitrous air, I propofcd an attempt to prcftve anatomical preparations, &c. by means of it ; but Mr Key, wh<> made the trial, foiuul, tiiat, after fome mon'.Iis, variou- animal fubllances were (hrivel- led, and did not prcfcrvc their forms in this kind of 155 air." picific The fpecific gravity of nitrous air, as well as of ravity of other kinds, ha^ Uuiw afcertaincd by Mr Kirwan. As itrous sir. ^ corrodes metals, he endeavoured to fiiul its weight by comparing t!ie lofs fullaincd by the materials which produce it. Thus lie fo'ind, that 14 grains of the materials produced 38.74 inches of nitrous air ; and, confcqucntly, by proper calculation, that the fpecilic gravity of nitrous air is to that of atmofphcric air as 119J to tooo. — " If this air (fays he) had been ob- tained over water, or in ftrong heat, its weight would probable have been very ditfcrcut ; as it is liable to be mixed witli phlogillicaied air, nitrous vapour, and a variable quantity of water. Nitrous vapour would render it heavier, and phlogifticatcd air or water pro- bably lighter." With regard to the conftitucnt principles, or ele- ments of nitrous air, all thofe who louk upon phlogi- fton to be a dillintl fiibftance, have believed that the former is a compound of nitrous acid and phlogiflon. By the oppofitc party, it is fuppofcd to be a fubilance entirely fimplc, and one of the conlHtuent partsof the nitrous acid. This opinion fcenis in part now to be entertained by Dr Prieftlcy hiinfclf, noiwithllan>!ing' his former fcntiments on the fubjedt. " I had no doubt on the fubjcct (lays he) until I read the worlc of Mr Mcthcric ; whoalierts, that nitrons air contains no proper nitrous acid, but only one of the elements of it; the other being dcphlogifticaied air, which had before been confidcrcd by Mr Lavoificr as the prin- ciple of all acidity Among other olif^rvations in fupport of his alTertion, Mr Methcrie has the follow- ing. I. Nitrous air burnt together with inflammable air, produces no nitrous acid. 2. Thoui;;h nitrous air be obtained from a folution of cierciny in the nitrous acid, alnioll all the acid is found in the folution. 3. Nitrous air, abforbed by r.:arlac acid, docs not make aqua rcgia. 4. \\c is of opinion, that a fmall poi tioii of the nitrous acid being dccompofcd, furniihcs.i pure air, fo altered, that, uniting with inrtammable air, it chan^jcs it into nitrous.air. " In reviewing the experiments I had ffirmcrly made on this kind of air, I could not recollect any of thciu in which tie pure nitrous aci J was produced, ex- >37 'oiupo- cnt p.:>rts r nitrous cepting tint with dcphlogidicstcd air, bcfides the ex- periment in which it was decompoftd by the electric ipark ; which fiirni;!ies a (Irong objection to this hy- pothciis." To afcertain the matter more full/, the following experiments were made. " When nitrous air is dcconipofcd by iron, or by a mixtureof iron and fulphur, the water, over which the proccfs is condutted, acquires no acidity ; but 1 had iuppofcd that all the acid was abforbed by the iron. Having by me a quantity of this iron which had been reduced toperfeiJtnifl in nitrous air,and which,! knew, iwil have imbibed more tjian its wti'^ht of the air, {thought that the acid might be obtained from it by diftiUation ; bjt a quantity of this ruft of iron, dillili- cd i:i an earthen retort, yielded neither nitrous air nor nitrous acid, at lead in any quantity that could fa- vour the common hypothefis. " 1 then endeavoured to decompnfe nitrous air by heating iron in it with a burning lens ; and in this proccfs 1 fuccecded farbeyoiidmy expectation: for tlic air was prefently diminillied in quantity, while the iron became of a darker colour, was fometinics melted into balls, and gathered co;;riderablc weiglit, though it had no appearance of coutainiiig any nit-.ous acid In :lte lirii experiment, the original quantity of ni- trous air was diminillied to about oac-third ; and after this, it was increafed." The increafe was found to arife from a production of inriammable and dephlogi- llicated nitrous air. The Doctor proceeded to try various other experi- ments on the decompofition of nitrous air, particularly that of burning Homberg's pyrophorus ; but without any fuccefs, or obtaining tlie fmallcll particle of ni- trous acid. His concluiions from the whole are the following. 15S " Water feems to be a nrceflary ingredient in r.i- Nitrou-iair trons as well as intlamniable air; at lea II without a *<'""!'"''"^ quantity of water, nitrous air cannot be formed. For",' ['"'"(f')- 1 Ml 1 i-,r 1 1 • /I tl^atcd ni- example, copper will be diliolved in Itroiig mtrous jj.^yjjjj;j acid without producing any nitrous air, jult as iron 3^4 water. may be dilFolved in concentrated vitriolic acid without producing inriammable air. " That nothing is nrcclfary to the formation of ni- trous air belidcs phlogillicaied nitrous acid and water, is evident from the production of it by the impregna- tion of pure water with phlogillic.itcd nitrous vapour formed by the rapid folution of bifmuth ; an experi- ment which I mentioned before. However, to make it in a more unexceptionable manner, I interpofed a glafs vell'el between that in which the folution was made and that in which the water to be impregnated with the phlogillicaied vapour was contained, iliac whatever was diftilled over by the heat of tlic procefs might be prevented from reacliing tlie water. l;i thcfc circu'n (lances, however, when nothing but the dry phlojillicated vapour could enter the water, it be- gan to fparkic and yield nitrous air very copioully as foon as it had received a bUicr tinge from tiie impreg- nation Nitrons air is alfo produced by pouring a highly coloured or phlngiiticutcd nitrous acid isto pure wntcr, in whicli no metal or earthy matter is any wav concerned. 159 " I have foiincrly obfcrved, howreidily nitrous air Effea-> of is diminithed by taking the electric fpark in it.

Letting it ftand all night upon the mercury, it was in- crc.ifcd in the proportion of 1 1 ', to 24 ; feemingly by • the acid uniting to the mercury and generating more nitrous air, llncc it had that fmell.

But even this water did not acquire any acid talle, but ojily an ailringent one." The Doftor concludes his experiments on this fub- ]t6i with a conjedure, that the phlogirton, and nei- ther the heat nor light of the eletlric, contributes to the decompolition of nitrous air. As his final fcnti- luentson the matter, however, are merely conjefture, without any certain experiments to confirm them, we Iliallliere refcrthe reader to his Section on Theory, at .the end of his lixth vohime of experiments, &c.

It may alfo be obtained in fome part of the proccfs of procuring nitrous air from iron, though with this metal the fuccefs is uncer- tain; but tin yields a confidcrablc quantity of it. By cxpofing iron to nitrous air, it may be fo far dcplilo- gifticated as to admit a candle to bi;rn in ir. Dr I'riert- ley filled an eight-ounce pliial with nails, and then with mercury ; and difplacing the mercury with nitrous air, left the phial inverted iu a quantity of the fame fluid. Two months after, the nitrous air was found to be changed in fuch a manner as to admit a candle to burn ia it with its natural flame ; and by continuing fiill longer in contael with the iron, a candle would burn iinitwith anenlargcUiiame. TJiefc changes, however, LOG Y. Scdl.X. arc very irregular, fo that they feldom product the like ncphlopif- etteds with the regularity one might expect. Dr tuatcd Ni- Prielllcy once found, that by the contad of iron in "•""» '^^J- _ qtiicklilvcr, it was fo changed as to be tired with an CKplofion like a weak inflammable air ; wliilll another quantity of nitious air, which liad been treated in like manner for about the fame length of time, only ad- mitted a candle to burn in it with an enlarged tiame. f j. In that fedion of his lall volume in which tlic Doc- Compo- tor treats of this kind Lif air, he obfcrvrs, tliat water is nsnt parts abfolutely neceliary to its conipolition, or rather to the ^\ 'I'l'hlo- decompolitiou uf rhe common nitrous air by iron. He f?'''""''^". had dccompofcd it before, either by previoully tilling '" """"' ^ ' the veifels that were to contain the nitrous air with water or with mercury ; though it had always requi- red a much longer time when the latter was made ufc of. The rcafon of its being formed at all in this lad way, was a fmat! quantity of moillure adhering to the infide of the velFcl containing the mercury. jfii To try the influence of water in this cafe, he now JSficifts of procured a number of very clean fmall needles ; and ^^'»t<:'■ on having made a phial, and likewife a proper quantity of "'"*»• '"■• mercury, quire clean and dry, he put the needles into the phial, and, filling it up with mercury, introduced the nitrous air : but it continued in this way for lix or eight months without the fmallcit alteration. Intro- ducing a few drops of water, a diminution cf about one-third of the air took place, and the remainder ap- peared tobe phlogiflicated. On the 26th of May 1782, lie examined a quantity of nitrous air, which had been confined with iron-lhavings from the 27th of Augufl preceding, when he found one-half of itabforbed ; the remainder fupported the flame of a candle better than common air, though a moufe died in it ; and yet this air had continued feveral months in the fame flate with regard to quantity, nor was it at all probable that its quality would have been altered by any Icngtli of time. ffij Though this kind of air is produced by the contaft BcTl me- of iron and nitrous air, the Dodor has never been able '''o** °f to afcertain tlie quantity of nitrous air which a given foc^r'^E quantity of iron can decompofe; and though ironfoon "" becomes fo much afleded by this proccfs that it crum- bles into powder, it llill feems equally capable of dc- compofing a frelh quantity. Having made a compa- rative experiment, by putting together one quantity of nitrous air with frefli iron and another with ruil, he found that in both the air was dirainillied to about one- third, and a candle burned in both equally well ; but neither of them had the properties of frcfn nitrous ai^ in any degree. As the proccfs forobtaiuing dephlogifticated nitrous air by means of iron is very tedious, the Doctor en- deavoured to find another which might be attended with lefsinconvcnience. This heaccomplilhed by dif- folving turnings of iron in a dilute folution of copper in nitrous acid (the fame that remains after the pro- dudion of nitrous air), mixing it again with an equal quantity of water. V/ithout this precniion, he tells us, that though the iron will at firfl be adcd upon very flowly, yet the mixture will at length grow fo hot as adiially to boil, and the procefs will be exceedingly troublefomc ; however it will be necelfary previous to any attentpt to difTolve the iron, to heat the folution of cojpper, ill order to expel all tJie nitrous.air and fuper- fluous ft.

Without this precaution a quan- tity of common nitrous air will be produce J. Dcphlogifticattd nitrous air is abfurbed by water al- inofl as readily as fixed air, and in conddcrable quan- tity ; the liquid taking up about one-halt" its bulk of air. After being thus faturated, the whole quantity of dcphloj^irticatcd nitrous air may be expelled pure by heat, anil iscallly received in velkls containing mer- cury. It was lil>cuirc obfcrvcd, that as this kind of air mucli rcftniblcs fixed air in its properties of being imbibed by water, and expelled again by heat, it rc- fcmblcs it alfo in this farther properly, that all the air which ha.s been actually incorporated with the waier will not be imbibed by water again. But the propor- tion of this part is three or four times greater than the corrcfponding part of fixed air ; it is alfo conlicierably more phlogidicaccd. Water impregnated with it very foon parts with it again on being expofcd to the atmo- fphere. — It difcovcrs not the fmallefl trace of contain- ing cither acid or alkali. Its fpecific gravity is lefs than that of common air. On heating red precipitate in this kind of air, pure phlogillicaled air was pro- duced without afFecHing, or being affcfted by, the ni- trous air. Repeating the experiment with malleable iron, the quantity of it was enlarged, and the whole phlogilUcated, without any mixture of fixeii air. By healing bits of clean crucibles or retorts in this kind of air, it fecmeJ to approach in quality to common atmo- fpherical air ; and the effects were always found to be the more conlidcrable the longer the procelswas con- tinued. On attempting, however, to determine whe» ther this change in the conflitution of dcphlogifticaied nitrous air was occafioned by means of heat or liglit, he heated it in earthen tubes ; but found, that though thcie were glazed both 011 the outlide and infidc, and feemcd per^ftly air-tight both before and after the ex- periment, ihe air had efcaped. By the elejlric fpark it was rendered wholly imniifcible with water, and brought to the llandard of 1.45; fo that the Doctor had no doubt of iis being re fpirable. Yet this kind of air, though it admits a candle to burn fo well in it, will not kindle pyroplrorus, though the nitrous air from which it is produced would inilantly fet it on fire. Sect. XI. Of Vitriolic, Nitrous, Mariiif, and other AciJ Airs, \ I. Vitriolic aci:i Air This is always a combina- tion of vitriolic acid with phtogifton, and conlVijuently may be procured from any mixture of that acid in its higlilyconcentratcdflate with phlogi (lie matters. Hence it is obtained from all the metals, gold and platina ex- cepted, on boiling them willi (Irong oil of vitriol. It is'alfo procurable from the fame acid rendered black by any phlogiftic matter. No greater heat is required to expel this kind of air than ihat produced by the flame of a candle. It is the heavieftof all aerial fluids, next to fluor acid air, being to comnicwi air as 2265 to icoo. Dr Prieftley informs us, that a quantity of vitriolic acid thusimpregnatcd with phlogilton, will yield many times more air than an equal quantity of the il: on jcII fpirit of fait — When the vitriolic acid air is produced jngreatplenty,the topof the phialin which it is gene- rated is commonly filled with white vapours. The air has alio thefamc appearance asit is tranfmiticd through 3 the glafs tube ; and it is fometimes difcovcrablc in the Nitroi!^ recipient. When fuch fubflanccs arc put to the oil of '^^ '^ '^^r- viiriol ascaufeagreat cftervefccncc with that acid, care '' ' Ihould be taken to a.

By tliis means I conclude that the tube is filled with a pure red vapour, without any juixture of nitrous air, and pcri;aps common air alio." For a further account of the properties of nitrous acid air, fee Chemistry, {^Ir.dix.) \ 5; Of Alari/ic Ac;f yjir The marine acid, by Vat, may be refolvcd into a permanently claiHc and tranfparent inviublc vapour, which, however, is more calily preferved in itsacrial Hate than nitrousacid air, as the former has no effect upon cjuicklilver. An eafy, and cheap method of obtaining this kind of air is by filling a phial, litted with a glafs tube and Hopper, with common fait, and then pouring a fmall quantity of oil of vitriol upon it ; which, by the alfillance of heat, will difengage the acid principle, or the marine acid air, from the fait. " A phial (lays Dr Pricltley ) prepared in this manner will fufRcc, for common cx- periinents, many weeks ; efpecially if fomc niore oil of vitriol l)e occalionally put to it. It only requires a little more heat at the lall tlian at the firft. Indeed, at firfl, the heat of a pcrfon's hand will often befuf- ficieni to make it throw out the vapour. In warm wcatiicr it will even keep fmokiug many days williout the application of any other heat. On tl)is account it Ihould be placed where there arc no metallic uten- lils which it can corrode ; and it may ealily be prr- ceiveil when the phial is throwingout thisacid vapour, as it always appears in the open air in form of a light white cloud." After the marine acid has yielded all the air that can be expelled from i:, it is extremely v/eak, fo that it can but barely corrode iron. The gas itfelf is con- liderably heavier than common air, the fpecilicgraviiy of the two being in the proportion of five to three ; .1 cubic inch weighing 0.654 grains. It is very fatal to animal life, but leYs fo tlu'n pure nitrous air ; for flies and fpiders live longer in marine acid than in ni- trous air. In dipping a candle into ajar of this air the flame is extiiiguillied ; but the moment before it goes out, and alfo when it is afterwards firfl lighted again, i: burns with a green or light-blue fiame, like that of conimou fait thrown inta a fire. Its diminu- tion by the eledlric fpark is barely perceptible, ice is dilfolved by it as fall as if it touched a red-hot iron. It is partly abfjrbcd by ahno'l every fubllance con- taining phlogifton. and the remaining part becomes inHammablc. Oilof olives abforbs it very (lowly, and oil of turpentine very fill ; by which ihcy both be- come almoll black, and the remainder of the air is in- fiauMnablc. ElVential oil of mint abforbs marine air pretty fad, becoming brown, conliflcnt, aad fo heavy as to link in water ; and its fmcll is in great mcafurc Fluor Aci altered.

A fmall bit of phofpl'orus changed fmokcd and gave light in this acid air ; and the elallic i"to in- fluid was but little dimiuifliedin twelve hours. On */""'"^l'l< the admillion of water, about four-fil'ths of the gas""'" were abforbed, and tlte refl was inflammable. This change was alfo cfl'eded by a great number of other fubAanccs : fomc of whi:h, however, require acon- fidcrable time to produce their efFefl ; fuch as crulls of bread not burned, dry wood, dry flefli, roalled pieces of beef, ivory, and even Hints. beeCtiEMisi kv, (//i- ^..•..) § 4. Of ill! or Acid jlir The difcovcry of fluor a- cid air was made by Mr Schcele, who obtained it by di- Hilling the fpar called ihior with vitriolic acid. Dr Priellley, W'homade feveral experiments upon the fub- 175 JC(51, was of opinion that this new acid was only the lliffcrcrt vitriolic difguifed by its connexion with the fluor. f™"' ^■"" He even fuppofed that he liaJ produced it by pouring elio acid air. vitriolic acid on other phofplioric fpars : both thcfc ' opinions, however, he has now retracted, and believes the tluor acid to be one of a peculiar kind. Its moH remarKablc property is the great attraction it has for liliceous earth, fo that it even corrodes and makes holesin the retorts in which it is diHilled. See Che- mistry, {hiJex). § 5. Of the Vegetable atij other Acid Air By- means of heat alone, the concentrated vegetable acid emitsapernianently elallic and aerial fluid. This has the properties of the acid of vinegar ; but, like it, is weaker than the rcH of the miueral acid airs, tlibugh it agrees with theui iu its general characters. Water imbibes it as readily as any of the other acid airs , oil- olive readily abforbs it, and in confiderable quantity, loliug at the fame time its yellowilli colour, and be- j coming quite tranfparent. Common air is phlogilli- phloirifti- cated by it, as it is alfo by the liquid vegetable acid, cates conv As the vegetable acid, however, from which this air moii air. had been obtained, was diitillcd by oil of vitriol, the Doctor fufpecled that what he had examined might derive mollof iis properties from the oil of vitriol, and rather be vitriolic than vegetable acid air. 175 An acid air, fomcwhat difTcrent from any hitherto Air from defcribed, was obtained by Dr Prieflley from the va- folutiou a pour arillng on diltilling to dryncls a folution of gold R°'''' in marine acid impregnated with nitrous acid vapour, which makes the bell kind of aqua regis. <' The produce (fays hel was an .icid air of a very peculiar kind, partaking both of the nature of the nitrous and marine acids ; but more of the latter than of the for- mer, as it extinguiflied a candle ; but it was both ex- tinguillied and lighted again with a mofl beautiful deep blueHame. A candle dij>pcd into the fame jar with this kind of air went out more tjian 20 times fncceffivety, making a very plcaling experiment.

But though a vaft quantity of fixed air cfcapcs du- ring this proccfs of fermentation, a very conlidcrablc portion ilill remains united with the fermented liquor, and to this it owes all its brilkncfs and agreeable pun- gent acidulous tallc ; for wlien the fixed air is totally evaporated, the liquor becomes entirely vapid anil Hat. Hence aUo we are furnillied with a mcthodof rcftoring the brifknefs tothefe liquors after they have loll it in confcqucnce of being cxpofcd to the aimofphere. Viz. by imprcjinating them again with tixed air, either na- turally or artiticially produced. Dr Pricftley has made feveral experiments in order to determine the quantity of fixed air contained in fe- veral forts of wine. His method was to take a glafs phial (fitted with aground flopple and tubcj, capable of containing 11 ouncc-meafurc. This he filled with wine, plunged it into a proper vcllel of water. The . whole was Uien put over the fire, and the water, into • which the phial was plunged, fullered to boil. The end of the tube being placed under the mouth of an inverted receiver filled with quickfilvcr, the heat ex- pellcdthe fixed airfroui the wine, which entering into the receiver, afccndcd in bubbles through the quick- lilver to the top, pufliing out part of the metal and ta- king its place. The refult of his experiments was as follows : C Madeira Port of iix years old Hock of ti\c years Barrelled claret i Tokay of 16 years i^oz. nieaf. t.f j Champagncoftwoyears (_Bottledcydcrof ijycars |_ g Oh I T»T I I ,'.

During the acetous fermentation alfo, liquors emit a. vapour, great part of which is fixed air, though the nature of its otJicr component parts has not yet been ihorov.ghly afcertained. " Fixed air is likewife produced, though in no great qua!!tity, by putrtfaJlion. In this cafe, however, a great part of the elaftic fluid conlilTs of infianunable and phlogiflicatcd air, and the fixed air iifclf fecms to be intimately connet^tcd with a putrid otfcnfivc efiluvi- \\m. It fcemed to Dr Pricftley to " depend in fome nicafure upon the time and other circumllancts in the (dilibhuion of animal or vegetable fubilances, whctlicr they yield the proper putrid diluvium, or fixed or in- f.amnublc air." The elaftic fluid produced by putrefying vegetables, when kept in a moderate degree of heat, is almoft all liscd air ; while that from animal I'ubftances contains feveral times more inflammable than fixed air. Vege- table fubftances yield almo/l all the permanently elallic fluid in a few days, but animal bodies continue to emit it for feveral weeks. When the tlaftic fluid yielded by animal fubftances is abforbcd by water, and that water boiled, the fixed air may then be obtained with- out any mixture of the putrid cflluvium. It is alfo to be obfervcu, that the quantity of elaftic fluid produ- cible from animal fubftances is various according to *the nature of the partsof the animal employed. Thus the mafcular parts will vicldlcfs elaftic fluid, and alio Icfs mixed with any putrid or offenfivc eflluvium, than Of Artifi- a whole animal, or than the liver, &c. Thcpropor- cial Airs. tion of inflammable and of fixed air is alfo various, ac- ""^ ' cording to the various pans employed. (2.) By hcut. In every combullion, except that of fulpluir or of metals, a quantity of fixed air is genera- ted. This may be obferved by fixing a lightetl candle in an iuvcrtcd receiver overa bafon of lime-water, for a precipitation of ilic lime \\ill prefently cnfuc ; and the fame precipitation (which is one of the charaflc- riftics of fixed air) will always cnfue, whether a candlcj a burning piece of wood, or, in Ihort, any other com- buftible fubftance, ejj^ccpt fulphur or metals, be made ufe of. During this production or extrication of fixed from atmofphcrical air, the latter is commonly fuppofcd to be conlidcrably diminilhed, though M. Lavoificr and Mr Scheele have now rendered that opinion doubt- ful. If a piece of charcoal be burned by tlirowing the focus of a lens upon it when contained in a glafs- recciver inverted in water, after the apparatus is cool- ed, the water will have mounted a fmall way into the receiver. The diminution, however, is limited, and depends on feveral circuniftances. Dr Hales has ob- ferved, that, in equal receivers, theairfuflers a greater diminution Ijy burning large candles than fmall ones; ** and likewife iliat, when equal candles arc made ufe of the diminution is greater in fmall than in large recei- vers. The caufe of this phenomenon probably is, that the air contained in the receiver cannot all come into contad with the flame of the candle ; whence, as fooa as the air which is nearcft the flame becomes conta- minated, the candle is extinguiflied. Thus the author of a Concife Trcaiife on tlie Various kinds of Perma- nently Elaftic fluids, has diminilhed the air of an in- verted receiver one fixih part, by moving the candle whilft it burned through the different parts of the vef- fel, fo that the flame was brought into contact with a greater quantity of the confined air than if it had re- mained in one fituation till it became cxtinft. Dr Mayow obferved, that by the burning of a candle the air was diminilhed of one thirtieth only; Dr Hales found it to be diminifiied of erne twenty fixth part ; and Dr Pricftley found it to be diraini.htd of one fifteenth or lixtcenth. Mr Cavcndifli obferved, that air fuf- fercd adiminutionof one-tentii of ihc whole quantity, by palling through an iron-tube filled with red-hot powder of charcoal. A candle, or any other combuf- tiblebody, willceafe to barn by iifclf, and confequeiuly to contaminate a quantity of confined air much Iboner than when it is, in fome manner, forced to burn by the external application of heat. " The focus of a burn- ing mirror," fays Dr Pricftley, " thrown for a fuffi- cicnt time either upon brimftone or wood, after it has ccafed to burn of its own accord, and has become charcoal, will have a much greater effect of the fame kind, diminilhing the air to its utmoft extent, and making it thoroughly noxious." The combuftion of the phofphorus of urine diminilTies air in a great de- gree. Mr Lavoifier has obferved, that by the com- buftion of phofphorus, air may be diminilhed of about one-fifth or onc-fixth . This accurate philofopher has alfo obferved, that the acid of phofphorus thus formed, acquires the weight loft by thediminiflicdair ; finding that about three inches of air were abforbed by every one XIV. A R O one grain of phofphorus, when the experiment was tried with a receiver inverted in water, upon the fur- ficc of which a I'mall quantity of oil had been intro- duced ! but when the receiver was inverted in quick- filver, the abforption wasconftantly between twoone- fourth and two three-fourth inches for each grain. Mr Cavallo mentions his having often repeated ihe expe- riment of burning phofphorus in a glafs tube inverted in water, by applying the clofcd part of the tube, wherein the pliofphorns was contained, to a pretty ftrong fire, when he always obfcrvcd that the utmoft diminution of the inclofcd air cffedled by this means was full one-fifth. • Dr Hales remarked, that after the extinftion of candles in a receiver, the air continued todiminilh for fcveral days after. This may be owing to the gradual abforption of part of it by the water ; it having been remarked by Dr PriclUey, " that this diminution of air by burning is not always immediately apparent, till the air has palled fcveral times through water ; and that when the experinientwasmadewithveirds Aandingin quicklilverinftead of water, the diniinutionwasgent ral- ly inconfiderable till the air had palled through water." In thefe experiments of burning conibullible bodies in a quantity of air, and meafuring the diminution, we fhould always remark two caufes of miftake, viz. the abforption of air by the coaly rcfiduum of the burned matter, which fometimes is very conlldcrable, or by the fluid in which the receiver is inverted, and the produdion of elallic fluid from the burning fubftan- ces ; thus gunpowder generates a great quantity of claflic fluid when inflamed, &c. Even the eleftric fpark feparates fixed air t'rom com- mon atmofpherical air ; for when a number of thefe fparks arc taken in a fmall quantity of common air over lime-water, a diminution-will take place, the lime will be precipitated, and if we put a blue vegetable juice inftead of the lime-water, it will be turned red by the acidity of the fixed air depolitcd upon it. Dr Prieftley having cemented a wire into one endof a glafs tube, the diameter of which was about one-tenth of an inch, and having fixed a brafs ball to that extremity of the wire which was out of the tube, filled the lower part of it with the juice of turnfole or archil, fo that a quantity of common air was contained in the tube be- tween the extremity of the wire and the furfacc of the liquor. Then takingthceleclricfparksbetweenthe laid wire and liquor for about one minute, the upper part of the liquor began to look red, and in about two mi- nutes it was manifelUy fo. The air at the fame time, was diuiinidied in proponionas the liquor becamered ; but when the diminution arrived to be one-fifth of the quantity of the air contained, then a longer elciflriza- tion produced no fenfiblc effed. " To determine," fays the doctor, •' whether the caufc of the change of colour W'as in the air or in the eledric matter, I ex- panded the air which had been diminifhed in the tube by means of anair-jnniip, till it expelled all the liquor, and admitted frclh bLie liquor in its place ; but after that, eledricity produced no fenfiblc cfFeft, cither on the air or on the liquor ; fo that it was evident that the rlcftric matter had dccompofed the air, and had made it depofit fomething that was of an acid nature." The calcination of metals, as already obfcrvcd, phlo- gifticaics, and confcqucntly diminidies common air ; LOGY. 18.7 but dots not produce any fixed air,fince the limc-Witer, Of Artifi- over which the cakii-.ation is made, dots not become c'pl Air». turbid ; and when metallic calxcS arc expofed to a fuf- ' ' ficiently ftrong heat, they in gtncral yield fomc fixed air : fo that it fecms that the fixed air v. hich is formed in the act of the calcination of metals is abforhed by the calx. Some fixed air may be obtained from red lead, by no greater degree of h eat than that 0} the dame of a-candle applied to the phial that contains it. igo The calcareous earths, v/hich, when arted on by Obuii.ci! acids, yield a vaft quantity of fixed airj produce a very fronieirkt fmall quantity of it when expofed to a ftrong heat by ^J ''Y*°* themfelves,in aproperveircl,cven when expofed to the " focus of a lens. Dr Pricftlcy, in his expcrin;ents re- lating to the production of dephlogifticctcd air from va- rious fubftanccs,whcnnioiftcUcJ with nitrousacid,aud afterwards expofed to a fuflicicnt degree of heat, gene- rally found that fome fixed air was produced together with the dephlogifticated air ; butofttn obtained fixed air only, without any dephlogifticated air being mixed with it, or fixed and nitrous air together. From half in ounceof ruft of iron, moiftened with fpirit of nitre, and ' dried, he obtained about a quart of elaftic fluid, about one-third of which was fixed and the reft nitrous air. From alhes of pit-coal, treated in the fame manner, he obtained nearly the like refult. But in thofe experi- ments, the Doftor moftly ufed a gun-barrel, into which he introduced thefubftancestobe tried ; fo that it ii very probable, as hejuftly obfcrves, that the iron might have contributed to the formation of the fixed air. In facl', when he tried lubftances of the fame fort,firft in a gun- barrel and then in glafs vcflcls, he obtained much more fixed air in the former than in the latter cafe. One of thofe experiments he made with tobacco-pipe clay, which, after being moiftened with fpirit of nitre, was when dry expofed to the fire in a gun-barrel7 and yield- ed fome elaftic fluid, which appeared to be wholly fix- ed air ; but repeating the experiment in a glafs phial with a ground ftopple, and taking the produced ela- ftic fluid at eight diflerent times, found that on the beginning fomc fixed air was produced, but afterwards the produce was dephlogifticated air. He made a fimilar experiment with flints carefully calcined in clofc velFcls, and obtained a fmiilar refult. ,^, Moft minerals contain fixed air, which may be ex- From diffc- tradlcd to a certain degree by means of heat. Mr rem mine- Krenger, diftilling a greenifli fulihle fpar, which was '■^• luminous in the dark, obtained from it fomc per.-ua- nently elaftic fluid, which, like fixed air, cryftallizcd a folutionof fixed alkali. Mr Fontana in hisanalyiisof the malachite, finds that that mineral contains a vaft quantity of fixed air, as pure as that whici'. is extracl- cd from chalk by means of vitriolic acid. From almoft every metallic ore and earthy mineral fome fixed air may be obtained, as well as from chalk, lime-ftone, marble, marine fliells, fixed and volatile al- kali, and from maguclia alba, by means of a violent fire, or of acids. In Mr Boyle's, Dr Boerhaave's and Dr K;'.lcs"j works, and in other books, the quantities of elaftic fluid generated in various procclTcs, and by divers fub- ftances, are mentioned with dilUnclion, but as thofe writers are not acquainted with thecharatHereftic pro- perties of fixed air, we do not know whether the elaftic fluid mentioned by them was pure fixed air or not.

The phenomena attending the produflion of fixed air from caLartoas fublUncis, &c. arc themrtlvcs very remarkable, and furnilh the fubjec'l of much fpcculation in phiKilophy. — The principal fads arc the following, i. Wlicn calcareous earths, alkalis, andinannefia, in thtir ufual ftate,arc mixed with acids, they caufcancftcrvcrccnce; and confciiutntly the production of a permanently ela- flic fluid, namely, fixed air. 2. Thefc iubflanccs re- tain the fixed air very obfliuatcly ; fo that a ftrong fire is nccefTary toexpcl it from niagnelia, and il.e ilron^eil is not fiifficicnt to expel it entirely from feed alkalis, and efpecially from calcareous earths (a). V«'hcn tliefe fubflanccs are treated with acids, they yield the fixed air, bccaufe they have a flrongcr attraclion to thofe acids than to the fixed air. 3. The calcareous earths which are infoUible in water, when dcj'iivcd of the fixed air becotnc fohible in it. Thus linic-Aonc is not foluble in water, but lime (viz. limc-flone deprived of its fixed air (is foluble in water. And if thofe fub- Aanecs, deprived of their fixed air, are put in a fitua- tion proper to recover their lofl fixed air, tlicy lofe the property of being foluble in water. Thus, when lime-water is expofcd to fixed air, the lime abforbs the •fixed air ; and, lofing at the fame time its property of being foluble in water, is precipitated from it in the llate it was before calcination, vi/.. of a ralcarcous earth infoluble in w'ater, and capable of cfiervcfcing with acids. 4. Alkalis, both fixed and volatile, when deprived of their fixed air, become more raullic, and more powerful folvcnts, incapable of crylhllization, and of efiervefcing with acids. But if to thofe alkalis, and alfo e?rihs rendered more cauflic, their fixed air be reftorcd, they acquire at once all the properties they had before they were deprived of the fixcvi air, viz^ they become more mild, eiTervefce with acids, rc- coven their weight, 8:c.

From tire fame property it may be alio ufcfully ap- plied to fcveral oeconomital purpofcs. Mr Ktnry found, that fixed air can preferve fruit for a conlidcr- able time. He tried a bunch of Italian grapes, which being fufpended in the middle part of Or Nooth's ap- paratus, and being fupi-licd with plentiful f^reanij of' fixed air every day, was prcfervcd without any ligns of decay for about one month longer than a limilar buucli fufpended in a decanter containing common air. Straw- berries and cherries he alfo found to be prcl'irveJ without decay fome days longer in fixed thin in common air. Indeed tlxcd air prefcrvcs not only fruit, but refills putrefaction in general. Dr Macbridc, in his elegant ellays on Medical and Philofophieal Subjccis,has pubtilhed various experiments wliich ic- rrsonflr.-.te this property of fixed air. He found, that not only good meat was preferved incorrupt for a con- fiderable tiiue, when c.xpofed to fixed air ; but that the putrcfudion of fubftances aftually putrid was im- peded by this means, and even that thofc fubtlances were reftorcd from the putrefcent to a found Hate. lij^ Tliat putrefaftion was cheeked by fermentation, was Refills pu- difeovcrd by Sir John Pringle ; and l)r M.iebride ob- trtfailion- fervcd. that tliis c
