Zy RICHARD KIRWAN, Ej; F.R.S. and M.R.I.A. 4 — BitkiiGe Bal O Nb ok Breacuinc being one of thofe arts which confift in fcarce any thing elfe than a particular application of fome of the general . principles of chymiftry, it might be expe@ted that the knowledge of the inftruments it employs would keep pace with the progrefs and improvements of that fcience to which it is fubordinate, and fo much the more as the nature of alkaline fubftances in general, which are its proper inftruments, has been in great meafure explained by the celebrated Door Black upwards of thirty years ago: Yet it has fo happened, that on a late occafion, when a fearcity of thefe faline fubftances, imported from foreign. countries, unhappily prevailed in this kingdom, it was ferioufly queftioned whether their place could be fupplied by materials B 2 manufactured Read April 4, 1789. Lad) manufactured at home. In the courfe of this difeuffion, it evidently appeared, from the contradictory teftimonies of many of the principal bleachers, that however they might excel in that art, when well provided with the inftruments they employ, they were but little acquainted with the general agency of the inftru- ments themfelves and their refpective powers, or even with the moft advantageous and ceconomical method of employing them. To elucidate thefe points by an analyfis of fome of the different fubftances employed by bleachers, and by giving a fure method of diftinguifhing the relative powers of every faline fubftance they may ufe, together with an account of the beft method of obtaining them, as well as of adapting them to the purpofe of bleaching, is the object of this paper. This tafk, which I have impofed upon myfelf folely with a view to the utility of the public, requires no ingenuity, and might have been long ago well executed by many others, if chymiftry, which has fo many votaries of the higheft rank in the moft civilized parts of Europe, had been more known and cultivated in this country, which perhaps of all others ftands moft in need of its affiftance, nd SECTION UR Sead ee fete y equine mr, BARILHA, Or this fubftance there are feveral forts made of different plants*, but the beft is that formed near Alicant, at a diftance from the fea, by the combuftion of a plant called by the inha- bitants bari/ba, and defcribed by Juffien in the memoirs of the academy of Paris for 1717, under the name of kak hif/panicum, Jupinum annuum, fedi foliis brevibus. It feems to be clafled by Linneus under the fpentandria digyn, by the name of fal fila vermiculata frutefcens foltis ovatis acutis carnofis, and fhould care- fully be diftinguifhed from the various kinds of /alicornia which he ranges under the title of monandria monogyna; and alfo from other plants which he calls chenopodia, which yield an alkali, but lefs pure than the /a//o/a. Thefe plants being dried to the fame degree as hay, are burned in pits nearly as kelp is with us, the afhes and falt run into a greyifh blue mafs, which is the barilha }, The beft fort is here called /zweet barilha. Tue fweet barilha which I examined was moft obligingly prefented to me by Mr. Byrne, an eminent merchant of this city. It was of a bluifh colour, covered over with a faline powder * See Colonel Conyngham’s letter, report of the committee of the houfe of com- mons of Ireland, 1788, p. 87. \ h ; t And by the French /oude, as being employed in foldering metals. exceedingly eit ae exceedingly hard, and had a fmart alkaline tafte. When broken it looked black in the fra€tured part, and vifibly contained pretty large pieces of charcoal. To find the proportion of fixed air in this fubftance, having reduced a quantity of it to fine powder, I poured on an ounce of it a fufficient quantity of marine acid, and found it to lofe by the action of this acid 80 grains of its weight, confequently one pound troy of this fubftance contains 960 grains of fixed air, (mixed with a little that had an hepatic fmell) that is exactly * of its weight. Other parcels contained fomewhat more, and others fomewhat lefs. As this fubftance evidently contained fome parts that were foluble in water and fome that were infoluble therein, to dif- cover the weight of each I poured on one pound of it reduced to fine powder thirteen pounds of water moderately hot, fucceffively ; this water had previoufly been boiled and filtered, and contained no other impurity than a flight trace of common falt. This quantity of water was neceflary to exhauft all the foluble matter in the barilha. Tue folutions were taken in fix different portions, none of them: betrayed the fmalleft mark of fulphur, of which I was aflured by trying them with the nitrous folution of filver, nor did the Pruffian alkali difcover any veftige of iron, By eighteen fucceflive evaporations and cryftallizations, I ob- tained 4881 grains of faline matter, the different fpecies of which I fhall prefently mention, and 2903 of infoluble matter. Ir hy ga | ae Ir may at firft fight appear extraordinary that the faline matter and the infoluble part fhould weigh more than the pound of barilha that feemed to afford them, for this amounts only to 5760 grains, and the two former weigh 7784 grains; but it fhould be confidered that thefe products were obtained not from the barilha alone, but from the barilha and the water in which the falts were diffolved, whofe cryftals retained a great quantity of it, and alfo from the air to which the folutions were expofed, and which they abforbed in large proportion. As the quantity of the infoluble matter was fubjeét to no fuch deceptive appearance, I began by examining the weight of that, for this being fubtra¢ted from 5760 grains neceflarily determined the true weight of the faline part, and as the ftate in which the faline part exifts in barilha depends in fome meafure of the earths and charcoal with which it is united, as well as the moft advan- tageous method of ufing it, I examined the nature and quantity of thefe very minutely. Havine therefore dried the infoluble matter for a confiderable time in a low heat until it appeared as dry as the barilha itfelf, and having found its weight in that ftate to amount to 2903 grains or 6,04791 ounces, I took one ounce of it, and drying it in a heat little below rednefs, found it to lofe 38 grains of moifture. ANOTHER ounce of the fame refiduum being treated with dilute marine acid loft 125,5 grains of its weight, and this lofs exprefles the quantity of fixed air contained in it, ANOTHER be ANOTHER ounce being calcined in a white heat for about one hour loft 200 grains of its weight, and on repeating this experi- ment I found the lofs amouint to 199 grains. LasTLy, on the 281 grains which remained after this experi- ment I poured dilute marine acid, and found the quantity of fixed air to be 106 grains. Hence I deduce the weights of the feveral fubftances diffipated by the calcination of an ounce of the infoluble refiduum of the barilha. ift, The weight of the fixed air loft was 125,5—106=18,5 grains. 2dly, The lofs of moifture was 38 grains. 3dly, The lofs of the fixed air and moifture amounted toge- ther to 56,5 grains. ‘This deducted from the intire lofs, that is from 199 grains, gives the lofs arifing from the combuftion of the charcoal, and confequently its quantity, 199—56,5=142,5 grains. I next proceeded to examine the fixed incombuftible part that remained after the above calcination. On the 279 grains of this, which remained after the calcination of an ounce of the infoluble part, [ poured a quantity of diftilled vinegar, whofe {pecific gra- vity in the temperature of 62° was 1,008, and digefted that refi- duum therein for fixteen hours in a heat little more than 100°. After edulcoration and deficcation I found the weight of what remained undiflolved to amount to 63 grains. Upon this expe- riment — rT @ 1 ‘Fiment I reafoned thus ?: 28 grains of a refiduum of this: fort con- tained 106 grains 6f- fixed air, ‘therefore’ the 279 grains: fubjected to’ the vinegar in’ this éxperimient gaufti‘have contained o109324 which wete diffipated bythe a@sor of the acid ;. there remained therefore of mere earth only 173576%3but! of. thefe 63 efcaped the , oF bey eae erage nae were ei Aa aM éarth; “(the barytie ‘Baie Hote “Expedied) thé ‘110° 56 that were diffolved mutt have confifted of ‘eithet or both’ of: thefe, ‘and’ the indiffolved 63 grains: mane have been ar gillaceous ‘of filicedts.” 3 BER Oop. 1 rose be HITE 9) [ To determine the firfe exe r ‘diftitiea” ina sleet retort rithe acetous folution, which was very yvoluminuus, until no more than about four pints Pane nicd: During the diftillation fome earth was depofited: which when dried ina red heat amounted to 4 grains 5 this I're-diffolved, and finding it precipitable by cauftic’ volatile, alkalitjudged itto be magnefia.

Besrpzs this I alfo obtained 127 grains’ of a mixture of mineral alkali and common-falt, which I could ‘not eafily feparate, and 346 grains of a mixture of vegetable and mineral alkali, with a {mall proportion of extractive matter, and fome digeftive falt, as I believe; this mafs conftantly attracted moifture. I weighed it hot and dry, but forgot to examine the portion ‘of fixed air it contained ; it could not be lefs nor much more than 28 per cent. and therefore this mafs contained about 250 grains of mere alkali. TueEse folutions, and particularly the laft portions, afforded alfo 125 grains of Glauber’s falt and 70 of common falt, but the Glauber’s falt at leaft did not exift in a cryftallized form in the bare and as 100 grains of it are reduced to 42 by expelling the’ water of cryftallization, no more than 53 grains of it can \ be pasa to have panes in the barilha. © re Turse fohitions alfo depoted 20 grains of eatihl Hewes iui dietis of, soe different seristedhesua| contained. in ong pops inset baritha ave, as, follows! yy, noi wid) vod a oe J C 2 Fixed Fixed air - - - - 960 Charcoal = - - 861,82 Calcareous earth - BS =~ | 542,86 Muriatic earth - ie Ai8) - 134 Argillaceous -— | Ae . m 131,23 ise Siliceous - : i Fen saa 249,58 J Mineral alkalipure o-. . - . 842 .

Tus falt was alfo fent to me by Mr. Byrne. It is exceeding white, and if not expofed to the air, very hard, and poffefles an alkaline tafte. ‘ THE quantity of fixed air and earth contained in different parcels of this fubftance is variable ; in fome ounces I found the quantity of fixed air to amount to 100 grains, in others to 1153 and therefore at a medium it may be rated at 107,5 prains, or 1290 grains, in one pound troy.

SECTION Ee ea Rey ks en IN IN To difcover whether any quantity of fixed alkali worth atten- tion exifts in any faline compound, diffolve one ounce of it in boiling water, and into this folution let fall a drop of a folution of fublimate corrofive ; this will be converted into a brick colour, if an alkali be prefent, or into a brick colour mixed with yellow, if the fubftance tried contains lime. Bur the fubftances ufed by bleachers being always impregnated with an alkali the above trial is in general fuperfluous, except for the purpofe of dete€ting lime. The quantity of alkali is therefore what they fhould chiefly be folicitous to determine, and for this purpofe : rft, Procure a quantity of allum, fuppofe one pound, reduce it to powder, wafh it with cold water, and then put it into a tea-pot, pour on it three or four times its weight of boiling water. adly, Weigh an ounce of the afh or alkaline fubftance to be tried, powder it and put it into a Florence flafk with one pound of pure water, (common water boiled for a quarter of an hour, and afterwards filtered through paper, will anfwer) if the fub- {tance to be examined be of the nature of barilha or pot-afh; or half a pound of water if it contain but little earthy matter, as pearl-afh ; let them boil for a quarter of an hour, when coo! let the folution be filtered into another Florence flafk. 3dly, eae Sti ot gdly, This being done, gradually pour the folution of allum hot into the alkaline folution alfo heated; a precipitation will immediately appear; fhake them well together, and let the effervefcence, if any, ceafe before more of the aluminous folution be added ; continue the addition of the allum until the mixed liquor, when .clear, turns fyrup of violets or paper tinged blue by raddifhes, or by litmus, red; then pour the liquor and precipitate on a paper filter placed in a glafs funnel, the precipitated earth will remain on the filter ; pour on this a pound or more of hot water gradually until it paffes taftelefs ; take up the filter and let the earth dry in it until they feparate éafily, then put the earth into a cup of Staffordthire ware, place it on hot fand and'dry the earth until it ceafes to ftick to glafs or iron, then pound it and reduce it to powder in the cup witha glafs peftle, and keep it a quarter of an hour in a heat of from 470° to 500°. 4thly, The earth being thus dried, throw it into a Florence flafk and weigh it, then put about one ounce of fpirit of falt into another flafk, and place this in the fame fcale as the earth, and counterbalance both in the oppofite fcale: This being- done, pour the fpirit of falt gradually into the flafk that contains the earth, and when all effervefcence is over, (if there be any) blow into the flafk, and obferve what weight muft be added to the fcale containing the flafks to reftore the equilibrium ; fabtrac&t this weight from that of the earth, the remainder is a weight exacily proportioned to the weight of mere alkali of that par- ticular fpecies which is contained in one ounce of the fubftance examined ; all befide is fuperfluous matter. I HAVE Iie ye I nave faid that alkalies of the fame /pecves may thus be dire@lly compared, becaufe alkalies of diferent {pecies cannot, but require the intervention of another proportion ; and the reafon is, becaufe equal quantities of alkalies of different f{pecies precipitate unequal quantities of earth of allum. Thus too parts by weight of mere vegetable alkali precipitate 78 of earth of allum; but too parts of mznera/ alkali precipitate 170,8 parts of that earth. ‘Therefore the precipitation of 78 parts of earth of allum by vegetable alkali denotes as much of this, as the precipitation of 170,8 of that earth by the mineral alkali, denotes of the mineral alkali. Hence the quantities of alkali in all the different fpecies of pot afhes, pearl afhes, weed or wood afhes, may be immediately compared by the above teft, as they all contain the vegetable alkali, and the dif- ferent kinds of kelp or kelps manufactured in different places, and the different forts of barilha, may thus be compared, becaufe they all contain the mineral alkali; but kelps and pot afhes, as they contain different forts of alkali, can only be compared toge- ther by means of the proportion above indicated. THE application of this teft is founded on the following principles : tft, That a hot folution of a free alkali, or of an alkali com- bined only with fixed air or fulphur, can hold no terreno or metallico neutral {alt in folution, though it may alkalino neutra falts or quick lime, if the alkali be free from fixed air. edly, That earth of allum cannot be precipitated either totally or partially by the hot folutions of any alkalino neutral falt, and therefore that its precipitation is always due to the prefence of a D free Ee] free alkali, or at leaft of an alkali combined only with fixed air or fulphur, to whofe quantity it is always proportional. It is true quick lime will alfo decompofe allum, but the prefence of quick lime is eafily difcovered by the addition of a few drops of any mild alkaline folution, and by the fame means as eafily fe-. parated. _ gdly, That if the earth of allum takes up fixed air, (which would increafe its weight) this air will be feparated by the heat em- ployed in drying it, or at leaft by the fpirit of falt poured upon it, and fo may alfo another heterogeneity which will hereafter be mentioned. I can fee but one inaccuracy attending this teft, and that of little moment ; it.is this, if the alkali contains fulphur, this will alfo be precipitated with the earth of allum and _ increafe its weight. The limits of this inaccuracy, at leaft in common cafes, fcarcely reach 2 or 3 grains, as we fhall prefently find. SuLPuourR is eafily deteed in any alkaline folution by faturating it-with an acid; hepatic air is generally developed, and the liquor becomes troubled. Not only the proportion but alfo the ab/olute weight of alkali in different alkaline fubftances or afhes may be found by this teft, as will appear by the following experiments: BECTION Sie Ct Tt Ge N V. f Of the Quantity of mere Alkali in diferent Alkaline Subfiances as exhibited by the aluminous Teft. CRYSTALLIZED SODA. I BEGIN. with this as being the pureft mineral alkaline fub- ffance in a dry form produced by art. Though it contains only » of its weight of real alkali, the remainder being water and fixed air, but the proportion of alkali being invariably the fame, it is the fitteft for a ftandard with which other fubftances con- taining the fame fort of alkali may be compared. I found that as much of this fubftance as would contain 480 grains of mere alkali would precipitate 725 grains of earth of allum dried and treated as already mentioned, and confequently that 480 grains of mere mineral alkali precipitate 725 of earth of allum. Noré, That in this and all the fubfequent experiments a little more earth of allum is precipitated than is mentioned, becaufe a little always remains in the filtering paper that cannot be had out of it, and I have reafon to think by weighing the paper before and after, that this quantity amounts to 3 or 4 grains; but as this defect is the fame in all cafes, it does not invalidate the comparifon. Dz SWEET m4 n °o | Sweet BarILHa, Tue folution of one ounce of barilha precipitated 174 grains of earth of allum; therefore, fince 726 grains of earth of allum require for their precipitation 480 of mere mineral alkali, 174 grains of that earth require 115,2 of mere mineral alkali. And confequently one ounce of barilha contains but 115,2 of mere alkali; and one pound of barilha fhould contain 1382,4 grains, This quantity exceeds by about 4 the quantity I found by direct analyfis, but poflibly one pound may contain more than another, for it could fearcely happen that I fhould commit a miftake of that magnitude. I must not here omit an odd appearance that occurred in this experiment: The earth of allum in drying acquired a bluifh colour, and when fpirit of falt was poured on it, to difengage the fixed air it might contain, the blue colour was more developed, and fome blue particles floated in the liquor. This feems to proceed from the tinging matter of Pruffian blue which has been found in barilha. The weight of this I have not examined, but it could not exceed I or 2 grains. CuNNAMARA Ke Lp. Tus was manufactured by Mr. Martin Mealy, and fent to me by Mr. Francis French, an eminent merchant in this city. It is a hard porous black fubflance, mixed with white and grey fpots, its fmell fulphureous, and its tafte mixed, being that of common falt and alkali. One ounce of it diffolved in marine acid [ at ] acid loft 24 grains of its weight, which efcaped in an aerial form. This air-was hepatic. Avnotuer ounce diffolved in boiling water left an infoluble refidue, which being heated in a crucible to rednefs weighed 165 grains ; this refidue effervefced with acids, and feemed for the moft part calcareous. Tue folution by the teft of the nitrous folution of filver evidently contained fulphur, and the Pruffian alkali gave manifeft figns of iron. Tuts folution precipitated 25 grains of earth of allum, and therefore contained 16,6 grains of mere alkali. During the pre- cipitation of the earth of allum much hepatic air was emitted, and the earth was fullied by the fulphur, though only a few grains of this can be prefumed to be mixed with it. To find the quantity of fulphur in this kelp I diffolved two ounces of it in pure water, and faturated the folution with ma- rine acid ; the liquor became turbid, and partly by filtration and part by fpontaneous depofition, (for fome of the fulphur paffed through the filter) I obtained 8 grains of fulphur, which gives 4 grains for each ounce, befides what exhaled in hepatic air. In order to eftimate the quantity of fulphur which a given quantity of mineral alkali is capable of containing, I diffolved 4oo grains of cryftallized mineral alkali-in fix times its weight of water, (this quantity of the cryftals contained 80 grains of mere alkali) and to this I added 80 grains of fulphur, and boiled them for ey | for half an hour; only 60 grains of fulphur were diffolved, by which I found that this alkali can take up nearly 3 of its weight of fulphur in the moift way; I fay nearly, as fome earth re- mained with the undiffolved fulphur. With this faturated liver of fulphur I precipitated a folution of allum, and found the pre~ Ccipitate to amount to 130 grains. Now 8o grains of mere mineral alkali can precipitate only 120,8 grains of earth of allum; therefore g grains of the above precipitate were fulphur. Yet this {mall proportion of fulphur was very vifible in, the earth of allum when heated to 500 degrees, by its ftrong yellow colour; therefore in. the precipitation of the earth of allum by kelp, in. which no fulphur was vifible, the proportion was incomparably fmaller, and no deduétion- need be made on that account, THERE.are-three methods of: defulphurating kelp, or any other alkalino fulphureous compound: The firft is by calcining it in an open fire by expofing it to a rapid blaft of air; and for this a very ingenious. contrivance was. devifed by my much refpeéted friend Mr. Witt1am: Dean. The only inconvenience attending it is that much of the fulphur will be converted into vitriolic acid, and thus combine with the alkali. The fecond is by fatu- rating it with a vegetable acid; and afterwards calcining it, by which means the vegetable acid will be decompofed; if this method could be cheaply executed it. would be the beft. "The third is by faturating a folution of kelp with fixed air: This I have endeavoured to effect by putting a folution of two ounces of kelp into DoGor Nooth’s machine for impregnating water with fixed air; the liquor foon became turbid, and emitted a ftrong hepatic fmell ; L294 fmell ; after the fulphur had fubfided I drew off the liquor, and with one half of it precipitated a folution of allum. No hepatic fmell was now perceptible, and the precipitate amounted to 40 grains. I dare not fay that this great increafe of power in the alkali was intirely owing to the defulphuration, but fome part undoubtedly was; yet the quantity of fulphur I could colle& was very inconfiderable, and mixed with coal duft. Kelp:may alfo be defulphurated by nitre, as fhall hereafter be fhewn. According to Do@tor Watfon, 30 ounces of kelp afforded hith 12 ounces of cryftallized mineral alkali, confequently 1 eunce would afford ,4 of an ounce, that is 192 grains, of which +, that is =38 grains, muft have been mere alkali. His kelp might have been better than that I ufed; but it is impoflible that his alkali was pure, as mineral alkali, when mixed with fucha quantity of common falt as is in kelp, can never be thoroughly feparated from it, but by proceffes which he certainly did not ufe, namely, by precipitat- ing a folution of filver in fpirit of nitre, eftimating the quantity of luna cornua, and afterwards decompofing the cubic nitre, or by faturating the alkali with diftilled vinegar, and diffolving the neutral falt thus formed in fpirit of wine, which leaves the common falt behind. Srrancrorp KELP. Tuts was fent to me by my worthy friend Mr. BravcGHatt. It was much denfer, lefs porous, and in appearance approached more to that of a vitrified mafs than Cunnamara kelp; it was at leaft equally fulphureous. ‘The folution of one ounce of it preci- pitated only 9 grains of earth of allum, and this earth was much more i. 24 - more difcoloured than that precipitated by Cunnamara kelp. The infoluble refiduum of an ounce amounted to 174 grains. VEGETABLE ALKALI, I rounp that 480 grains of the pureft and drieft falt of tartar (making allowance for the quantity of fixed air it contained) precipitated 331,5 grains of earth of allum. Dantzic Prart AsuH. Tue folution of one ounce of this falt precipitated in one experiment 200 grains of earth of allum; and in another 220 grains; at a medium 210 grains. Then if 331,5 grains of this precipitate require 480 grains of mere vegetable alkali, 210 grains of this precipitate require 304; therefore at a medium an ounce of this fubftance contains 304 grains of mere alkali, and a pound contains 3648. By my analyfis it contained 3477 grains; the difference is 171 grains. ? We may now determine which of two or more faline fub- ftances, one pofleffing the mineral, the other the vegetable alkali, is beft in its kind; for that fubftance is beft in its kind which approaches moft to its proper ftandard; 725, that is, the preci- pitation of 725 grains of allum being the ftandard of the good- nefs of an ounce of a fubftance containing the mineral alkali, and 331,5 being the ftandard of the richnefs of an ounce of a fubftance containing the vegetable alkali. Thus, if we compare barilha and Dantzic pearl afh, as the ftandard of barilha is to the quantity of earth of allum, an ounce of it precipitates, fo 1S L 2s] is the ftandard of Dantzic to the quantity an ounce of it pre- cipitates ; or 72521742! 33155! 79955 by which we fee that an ounce of Dantzic falt that would precipitate 79,5 grains of earth of allum would be as good in its kind as an ounce of barilha that ‘ precipitates 1743; therefore fince an ounce of Dantzic falt precipitates 210, it is Ticher in its kind by the difference between 79,5 and 210. i : Wirn refpeé&t to antacid powers the mineral alkali is ftronger than an equal quantity of the vegetable, that is, will faturate more acid, nearly in the proportion of 48 to 22; yet - it attraéts acids lefs, that is, with lefs force and activity, fince the vegetable will take them from the mineral alkali. But if the quantities of real alkali be unequal we may compare their antacid powers in this manner: As the precipitate by an ounce of a fubftance containing the mineral alkali is to 48, fo is the precipitate by an ounce of a fubftance containing the vegetable alkali to a number exprefling its comparative ant~ acid power. Thus with refpect to barilha and Dantzic falt, as 174:48:: 210: 58 nearly ; therefore the antacid power of Dantzic falt is greater than that of barilha, when taken in equal quantities in the ratio of 58 to 48. CASHUP. Tue beft fort, namely, that marked with the crofs arrows, is of a bluifh grey colour, exceeding hard and of a femivitrified appearance, its fmellifulphureous, its tafte fearcely alkaline, and does not attract the moifture of the air. With marine acid, one E ounce [ 26 ] ounce of it afforded 31 grains of hepatic air, When diffolved in water the refiduum of an ounce was 357.grains of a grey earth that appeared to be calcareous for the moft part. The folution itfelf was of a yellow colour and {trongly fulphureous, With the folution of allum it did not. effervefce ftrongly until a good deal was added, The precipitate was of a dirty white, and amounted to 66 grains, of which two appeared to be fulphur. Hence its quantity of vegetable alkali is nearly 93 grains per ounce. Mr. Crarke’s REFINED AsH: Tus I obtained from Mr. Crarxe himfelf. It is of a yellowith white colour, with greenifh fpots; many pieces are externally white and internally green; it is moderately hard, of a very fharp tafte, and effervefces with acids, An ounce of this fubftance diffolved in twelve ounces of boiling water did not effervefce with acids, but precipitated the folution of fublimate corrofive yellow and red as lime water does, and left a refiduum of 17 grains, which was evidently calcareous. A folution of two ounces of this fubftance being impregnated with fixed air in Doctor Noorn’s machine, depofited 5 grains of mild calcareous earth ; but a folution made in three or four times its weight of water, or without the affiftance of heat, contained no lime, and effervefced flightly with acids; and when this falt is fome time expofed to the air, its folution contains no lime. A soLuTion of one ounce of this falt precipitated 89 grains of earth of allum, and therefore contained 129 grains of mere vegetable tien vegetable alkali, to which if we add 17 grains of infoluble earth, we fhall find that the remainder of the ounce, namely, 334 grains, confifted of neutral falts; namely, digeftive falt, and perhaps tartar vitriolate, im {mall quantity. To prove the exiftence of thefe I faturated an ounce! of the folution of this refined afh with the nitrous acid, and then dropped into it the nitrous folution of filver; this latter was immediately precipitated in a curdy form, which as: the alkaline part was faturated could proceed only from the marine acid contained in the digeftive falt. In the report of the committee of the houfe of commons, dated April 1788, Mr. CLarke delivers an account of his method of manufactiring this falt. He mixes five parts weed or wood afhes with one part quick lime, and fuffers them to lie together in a heap for fix, nine or twelve months, and then extracts a ley from them which he evaporates to drynefs. By fuffering the lime and afhes to ftand together for fo many months, he imagines that the common falt contained in the afhes is de- compofed, and the quantity of alkali thus increafed ; but though it is poflible to decompofe common falt by quick lime, as Mr. Scueece has fhewn, yet this decompofition is effected by a very different management; and if in the firft part of Mr. CLarKe’s procefs fuch a decompofition were obtained, a recompofition would fpeedily be cfleétedin the fecond part of his procefs ; for fuppofing the marine acid to quit its alkaline bafis and unite to the lime, yet when the alkaline fait and marine felenite are both . drawn off into: thé ley, the alkali immediately decompofes. the marine felenite and reunites to its acid, according to the well He known [ 28 ] known laws of chymical affinity. So that by this long maceration (as he calls it) no advantage whatfoever is gained... However, Mr. CLARKe’s falt is undoubtedly a valuable preparation for the pur- pofe of bleaching, and may be obtained in a-fpace of time in- comparably fhorter than he requires, Tue neutral falts contained in the folution of Mr. Crarke’s refined afh do not proceed from any error in his procefs, but from the bad quality of the afhes he employs. Common Irish WEED ASHES. I OBTAINED a parcel of thefe afhes from Mr. CLARKE ; it was of a loofe texture, dark grey colour and falt tafte, mixed with charcoal, brick duft and other impurities. I chofe the cleaneft, and fitted it. One ounce of it loft by gentle drying 47 grains, and in a red heat 72 grains more. TweLtve ounces of the undried afhes being lixiviated, left a refiduum, which when dried weighed 4214 grains; the folution was reddifh, replete with extractive matter; it afforded a large quantity of digeftive falt, and fome tartar vitriolate, and very little alkali, Two ounces of the fame afhes being gently heated to a flight degree of rednefs loft 186 grains of their weight. One ounce of this calcined afh being boiled in fix ounces of water left a refiduum of 344 grains, and confequently contained 136 grains of faline matter; but of this faline matter only 22,4 grains were pure alkali, for the folution precipitated only 15,5 grains of earth of [29 J of allum; an hepatic fmell was perceived during the precipitation of the allum, and the earth was of a dirty colour. I rrrep alfo another fort of afhes which I had from a chandler ; it was of a whiter colour and cleaner. The folution of an ounce of it in fix ounces of water precipitated only 5,5 grains of earth of allum, and therefore contained but 8 grains of mere alkali. Tuere is a remarkable circumftance attending thefe afhes, namely, that if they be much calcined they feem to lofe their alkaline properties, and the folution no longer precipitates that of fublimate corrofive reddifh, as alkalies not thoroughly aerated do. What this circumftance depends on I have not as yet examined, but am almoft certain it proceeds from the prefence of common falt, as fixed alkalies and common falt melt very eafily, and thus unite to the earths. To eftimate the goodnefs of different afhes, fome have recom- mended the ufe of an hydrometer, whereby to difcover the {trength of folutions of equal weights of thefe afhes in equal quantities of water; but as this inftrument is equally affected by the prefence of neutral falts, as of alkali, it becomes ufelefs.

MrneRAL ALKALI may be procured more or lefs pure from the combuttion of the various fpecies of kali or falfola of Linneus, or from that of the different {pecies of falicornia and chenopodia, _ -mentioned by the fame author. The compounds thus formed are called barilbas or foudes. Tue cultivation of the falicornia may be feen in the fifth volume of the Memoires des Scavants Etrangers. A French acre (1,261 Englifh) produces one tun of this weed; and this tun when burned produces but 100 weight of barilha, and this of a kind inferior to {weet barilha. A {mall quantity of this alkali is alfo contained in kelp. I am inclined to think that much of the alkali is loft by its union with the earthy parts during the fufion effected in the common manner of fabricating this fub- ftance; and therefore the procefs fuggefted by Mr. Caper may be ufeful. He advifes a trench two feet deep, feven icet long, and eighteen inches broad, to be made, lined with clay mixed with fand, and over this iron bars two inches diftant from cach other to be laid; upon which a wall 2,5 feet high is to be conftructed, of limeftone if poffible; over the bars the dry fea weed is to be laid and fet fire to; the afhes will fall into the trench, i eS trench, and when it is full the fire is difcontinued *. I believe alfo that wafhing the fea weed in frefh water, to carry off the fea falt that adheres to it, would be ufeful. _To defulphurate kelp, Abbé Mazeas recommends projecting on it while in a red heat + of its weight of nitre; but this procefs feems too expenfive to be practifed in the great. 2dly, This alkali is found native in Agypt and feveral parts of the Ruflian empire, and perhaps may be cheaply imported. 3dly, Common falt may be decompofed after Mr. TuRNER’s method, by trituration with litharge, as the calx of lead here employed is afterwards converted into a yellow pigment. This method is very beneficial. I nave alfo contrived another procefs for decompofing com- mon falt. The particulars of my experiment were as follows : ft, I rendered the common falt pure by adding to its folution a folution of mineral alkali until all the earthy matter was de- pofited. 2dly, To a folution of three ounces of this purified falt in nine ounces of water I gradually added a faturate folution of 4,75 ounces of fugar of lead, both hot, until the folution of lead {carce excited any whitenefs in that of ‘the common falt. After one * Mem. Paris, 1767. ie & a one night's reft part of the fugar of lead cryftallized in the bottom of the veflel, by which it is plain that too much of it had been ufed. Thefe cryftals weighed 240 grains ; the fupernatent liquor I again evaporated to nearly 2, and after two days obtained large pellicles of acetous foda, which I feparated; they weighed 325 grains; to the refiduum, which ftill had a fweetifh tafte, I added a folution of mineral alkali, until no further precipitation ap- peared; a very fmall quantity of the alkali was fufficient for this purpofe. I then evaporated the remainder nearly to drynefs ; and afterwards heated it in a crucible to rednefs: In this heat it inflamed, and when calcined nearly to whitenefs, I took it out and diffolved it in twelve ounces of water, filtered it, and on adding an hot folution of allum obtained a precipitate, which when dried weighed 169 grains, and indicated the quantity of pure alkali to be 112 grains nearly. In this procefs nothing is loft, for the lead may be either revived or turned into a pig- ment, Laftly, Glauber’s falt may afford the mineral alkali, but moft eafily in the form of liver of fulphur: I endeavoured to decom- pofe it by the above procefs, but the quantity of alkali obtained from a large quantity of it was very inconfiderable, Or THE VEGETABLE ALKALI, Ir is univerfally known that this alkali may be extraéted in greater or leffer quantity, by lixiviation, from the afhes of almoft all vegetables, and it is now well eftablifhed that it pre- F exifts Ll & ] exifts in vegetables before combuftion; not indeed in a feparate uncombined ftate, but united partly with the vitriolic or marine acids, and fometimes the nitrous, but generally and for the greater part with a vegetable acid or oil, with which it forms effential falts, as they are termed. Thefe vegetable acids and oils are decompofed during combuftion, and thus the alkaline part is fet free; but the vitriolic by contact-with inflamed matter is converted into fulphur, part of which unites to the free alkali, which protects it from combuftion, and thus forms what is called diver of fulphur, a product found in moft athes, efpecially when the air has not had free accefs to them during com- buftion. As alkaline falts are of great importance in feveral arts, the proportion of afhes afforded by different vegetables, and that of alkali by the afhes of each fort of vegetable, has of late been accurately attended to, I fhall here prefent the beft authenticated refults of the experiments made with this view.

HENCE ks am Hence we fee that in general weeds yield much more afhes, and their afhes much more falt, than woods; and that confequently as to falts of the vegetable alkali kind, as pot afh, pearl ath, cafhup, &c. neither America, Triefte, or the Northern countries, poffefs any advantage over us. adly, That of all weeds fumitary produces moft falt, and next to it wormwood ; but if we attend only to the quantity of falt in a given weight of afhes, the afhes of wormwood contain moft. Trifolium fibrinum alfo produces more afhes and falt than fern. Most of the experiments on woods were made in France by order of government, under the infpection of the overfeers of the falt-petre works ; yet are to be read with caution by thofe that attend to the quantity of alkali with refpe& to bleachers; for as tartar vitriolate (a falt ufelefs to bleachers) is as ferviceable to the makers of falt-petre as alkaline falts, they have conftantly confounded one with the other; but the experiments made on weeds were inftituted by perfons who carefully difcriminated thefe falts: 100 grains of the falt of wormwood contain but fix of tartar vitriolate, and 100 grains of the falt of fumitary contain 15. All alkaline falts, unlefs mixed with lime, contain alfo + at leaft of fixed air, which produces no other effect in bleaching than that of reftraining their ativity. SECTION [38,1 SE wot an VII.

The earthy matter that remains is faid to be a good manure for clayey grounds. 4thly, The ley thus formed fhould be evaporated to drynefs in iron pans; two or three at leaft of thefe fhould be ufed, and the ley as faft as it is concentrated paffed from one to the other; thus much time is faved, as weak leys evaporate more quickly than the ftronger. ‘The falt thus procured is of adark colour, and contains much extractive matter, and being formed in iron pots is called pot afh. sthly, Fo sthly, This falt fhould then be carried to a reverberatory furnace, in which the extraCtive matter is burned off and much of the water diffipated; hence it generally lofes from 10 to 15 per cent. of its weight. Particular care fhould be taken that it fhould not melt, as the extra@tive matter would not. be thoroughly con- fumed, and the alkali would form fuch a union with the earthy parts as could not eafily be diffolved. I added this caution, as Door Lewis and Mr. Dossiz have inadvertently direfted the contrary. This falt thus refined is called pearl afh, and muft be the fame as Dantzic pearl afh *. For the moft ceconomical conftruction of a laboratory and furnaces for the above operations I refer to the defcription given in a French tra@, called Jart de fabriquer le falin © Ja potaffe; and fhall only add, that if the falt were extracted by a fire fupported by vegetables whofe afhes might afterwards be employed, no inconfiderable advantage would be gained. Pearl afh is fre- quently tinged green or blue; this colour it acquires during fafion, not from any union of the falt with phlogifton, as was formerly fuppofed, but by reafon of the manganefe contained in the afhes oe almoft all vegetables, as Mr. Scheie has fhewn. When it is calcined without melting it is perfectly white as Dantzic pearl afh. Y SECTION * The French call the refined ath ot afo, and the unrefined /alin. - [ 40 ] SeE Clearer soe VI. Of the Colouring Matter of Linen Yarn and its Solvents, Havine, through the obliging attention of Mr. ArsuTuNot, procured a fufficient quantity of alkaline ley faturated with this colouring matter, or, as the workmen call it, &7//ed, and which they are in the habit of throwing away; I found it to be a turbid liquor, of a reddifh brown colour, a peculiar tafte and ftrong fmell, affording no fign either of acidity or alkalefcence. On five quarts of this liquor 1 poured two ounces of weak marine acid; there was no effervefcence, but a copious depofition inftantly took place of a greyifh green colour, and the liquor freed from this depofit was of the colour of red amber. Tue next day I drew off the liquor with a fyphon, and poured two quarts of pure water on the depofited matter, and having agitated the whole, fuffered this matter again to fubfide, drew off the water, and added two quarts more; this liquor gave manifeft figns of acidity, and continued fomewhat reddith. Prefuming that after the addition of fo much water this acidity could not proceed from the fmall quantity of marine acid I had ufed, more efpecially as the liquor originally contained an alkali, in the faturation of which the greater part of the acid muft have been employed, I began to fufpe& that this ley contained an acid of its own, which was difengaged and feparated from the alkali by the marine acid as thé more powerful of the two; and hence I referved [see] referved the two quarts of liquor, laft added, for fubfequent experiments. Arter repeated affefions of cold water, when the characters of acidity were fcarcely any longer perceptible, I threw the de- pofited: matter on a filter and fuffered it to dry for fome time, it was then of a dark greenifh colour, fomewhat clammy like moift clay. I took a fmall portion of it and added to it fixty times its weight of boiling water, but not a particle of it was diffolved. The remainder I dried in a fand heat; it then affumed a fhining black colour, became more brittle, but internally remained of a greenifh yellow, and weighed 13 ounce. By treating eight quarts more of the faturated ley in the fame manner, I obtained a further quantity of the greenifh depofit, on which I made the following experiments : ft, Having digefted a portion of it in rectified fpirit of wine, it communicated to it a reddifh hue, and was in great meafure diffolved; but by the affufion of diftilled water the folution be- came milky, and a white depofit was gradually formed; the black matter diffolved in the fame manner. 2dly, Neither the green nor the black matter was foluble in oil of turpentine or linfeed oil by a long continued digeftion. 3dly, The black matter being placed on a red hot iron, burned with a yellow flame and a black fmoke, leaving a coaly re- fiduum. G 4thly, [a | 4thly, The green matter being put into the vitriolic marine and nitrous acids communicated a brownifh tinge to the two former, and a greenifh to the latter, but did not feem in the leaft diminifhed. Hence it appears that the matter extrated by alkalies from linen yarn is a peculiar fort of refi, different from pure refins only by its infolubility in effential oils, and in this refpec& refembling lacks. I now proceeded to examine the power of the different alkalies on this fubftance: 8 grains of it being digefted in a folution of cryftallized mineral alkali faturated in the temperature of 60°, inftantly communicated to the folution a dark brown colour; two meafures (each of which would contain eleven penny weights of water) did not intirely diffolve this fubftance. Two meafures of the mild vegetable alkali diffolved the whole. | One meafure of cauftic mineral alkali, whofe fpecific gravity was 1,053, diffolved nearly the whole, leaving only a white refiduum. One meafure of cauftic vegetable alkali, whofe fpecific gravity was 1,039, diffolved the whole. One meafure of liver of fulphur, whofe fpecific gravity was 1,170, diffolved the whole. One meafure of cauftic volatile alkali diffolved alfo a portion of this matter. THOUGH feuag J Tuovucu thefe experiments were fully fufficient to refolve my own doubts, yet to render ftill more fatisfaction to bleachers, I repeated them with the falts they generally ufe, and alfo with foap. I GHeREFoRE diffolved one ounce of fweet barilha, Dantzic pearl afh, Cunnamara kelp, caffup and-Ciarxe’s pearl afh, each in fix ounces of pure water, and putting in one ounce meafure of each folution, 8 grains of the green colouring matter, fet them to digeft in a heat of about 180° for 37 hours. At the end’ of this time I found that The Dantzic diffolved more than the barilha. The kelp as much as the Dantzic. The cafhup and Cuarke’s diffolved the whole. Hence I added half an ounce more of the folutions of Dantzic; barilha and kelp; the Dantzic and kelp then diffolved the whole, but of the folution of barilha two ounces were requifite to perform this effect. , I auso diffolved half. an ounce of Windfor foap in eighteen) ounces of water ; the folution was turbid, and could not be rendered tranfparent but when it was near boiling, and then it was very unmanageable, for when boiled it fpouted three feet high out of the bottle. Three ounces of this folution were requifite to diffolve: 8 grains of the colouring matter. G2 Now. [ 44 ] Now to compare the powers of thefe different folvents we muft remark, that as an ounce of barilha contains 115 grains of mere alkali, the folution of it being made in fix ounces of water, each ounce of the folution muft contain the fixth part of 115, that is I9 grains; and in the fame manner it will be found that an ounce of the folution of Dantzic falt contains 50 grains of mere alkali, that of Cunnamara kelp 2,8 grains, cafhup 15, CLARKE’ 21. THEREFORE 4,2 grains of faline fabftance of kelp performed the fame effet, As 45 of that of Dantzic, 38 of that of barilha, 15 of that of cafliup, 21 of that of CLARKE, 213 of foap. I auso tried the power of lime water, but found that three ounces of the ftrongeft diffolved very little of the colouring matter as fhould be naturally expected, for the three ounces did not contain above 3 grains of lime, nor did the mixture of fulphur render it more active. From the foregoing experiments we may now deduce the fol- lowing practical propofitions : if, Liver ae rft, Liver of fulphur is of all alkaline compounds the ftrongeft folvent of the colouring matter; next to this the cauftic vegetable, and after this the cauftic mineral alkali ; the mild vegetable and the mild mineral alkali occupy the laft place. Sulphur, it is faid, leaves a ftain in linen; but if liver of fulphur be ufed in the beginning, that is to fay in bleaching the yarn, the ftain will probably be removed by the purer alkalies afterwards ufed. Hence the folutions of kelp, cafhup and markoft are advantageoully ufed in the firft proceffes of bleaching, for which Dantzic and {weet barilha are lefs fit; but fix tun of kelp will be necefiary to produce the fame effect as one tun of cafhup ; yet as the former is manufactured at home it deferves the preference. adly, As the alkali manufaCtured from inland weeds is more powerful than the mineral, Mr. CLarxe’s is more powerful, or may be rendered fo, than any imported. It is already fufficiently cauftic, ‘and may be converted into liver of fulphur only by adding =; of its weight of fulphur to it when boiling, and thus it is fitted for the firft proceffes of bleaching. In its primitive ftate it is fit for the fecond procefs, and by rendering it) milder, which may be effeGed by burning half a bufhel of charcoal in a “pan in the fame room in which its folution ftands, it will be adapted to the laft proceffes, in which a lefs ative alkali is required, gdly, Cuarke’s falt converted into liver of fulphur is preferable _ to kelp, becaufe this latter, by the prefent manner of manufa@ur- ing it, holds charcoal in folution, this coaly matter it depofits on the 2a a the yarn, and thus leaves a_ black tinge; whereas Mr. CLarKe’s is free from this contamination, to fay nothing of the far greater quantity of alkali it contains, infomuch that one tun of CLARKE’s is nearly equal to eight tun of kelp. Hence it clearly follows that the linen manufa@ture ftands in no fort of need of foreign falts or afhes for the proceffes of bleaching. Tue chief defect in Mr. CLarxe’s manipulation is the lofs of time during what he calls the maceration of afhes and quick lime; by barely moiftening them the fame effe& may be produced in nine hours which he expeéts from their maceration during nine months, and much more lime is ufed than is neceflary. Dantzic pearl afh contains much more alkali than CLarke’s ; this muft proceed from the fuperior quality of the afhes from which it is extracted. 'Thofe I received from Mr. CLarKe were exceeding bad; nor do I believe that any crude afhes can be advantageoufly ufed in bleaching. But if fome perfons in the different manufa@turing counties would allot a few acres to the culture of wormwood and fumitary, I believe their own advan- tage, as well as that of the public, would thereby be confiderably promoted. An acre will, I fuppofe, fcarcely produce lefs than four tun of the dry weeds, and each tun will afford nearly 200 weight of afhes, and each tun of wormwood afhes will give nearly 1500 weight of unrefined falt, or 1300 of the refined. Tue alkali, manufatured after the manner I have indicated in the feventh feGiion, may not be fufficiently cauftic for the earlier Lee 4s] earlier operations of bleaching, but by the addition of half a pound of quick lime to every hundred of the falt, or of ten pounds for every tun, it will be rendered fufficiently fharp. There is no danger that any of the lime will remain in the ley; but if ~ any fhould it will immediately be difcovered, and depofited by the addition of a little of the unmixed ley.

Commencing at the upper part of his hole, he cuts out the coal about four inches in thicknefs from the floor as far as his pick will reach, then with wedges breaks it down from the roof, and continues his work in the fame manner to as great .a width as the nature of the roof will admit. In the middle feam above mentioned the — coal is cut out three yards in width, and pillars are left three quarters of a yard wide to fupport the roof: in the gank feam the coal is cut out five yards in width, and pillars of half a yard wide are left ftanding; but thefe pillars are in both feams occa- fionally broke through from hole to hole to promote a circulation of air, and for. the more conveniently drawing away the ~coal, He Sas To perform this kind of work the collier is neceffarily obliged to lay on his fide; on his knee he wears a piece of leather called a cap, on his thigh a piece called a pilch, and on his arm another piece called an elbow patch; and ufually works without any. other clothing than a pair of flannel drawers; and after having cut his coal is obliged to draw it in a bafket on a little kind of fledge, going on his fide feet foremott, dragging the coal after him to the foot of the fhaft (or pit) at which it is drawn to the furface by an horfe whimfey. The drawing the coal to the furface is contracted for at eight pence per quarter, and the colliers get the coal from the middle and gank feams for five fhillings and eleven pence per quarter, containing twenty-eight hoops, each hoop equal to one Winchefter bufhel, (the twenty- eight hoops weigh upon an average about 19C. 2qfs.) and in either feam the colliers can earn from two fhillings to half a crown, in working only fix hours. In places where there is a great confumption of coal and a proportionable price, feams of the thicknefs I have mentioned may be worked to advantage, provided the roof above the coal is good, that is, if it will ftand for a tolerable width without the fupport of timber; but where much timber is required under ground, or where from the local fituation of the colliery expenfive machines are neceffary to draw off the water, but little hopes of profit can be entertained from fuch very thin feams.

By the Reverend M.eYOUNG, D.D. F.T.C.D. and MRI. A. 1. N oTWITHSTANDING the furprifing things that have been effected by the architeéts of the middle ages, in raifing fuch ftupendous piles on fo flight an apparent fupport as the pointed arch and flender Gothic pillar; it feems that their fucceffors have not, with all the care which the fubje@ deferves, confidered how far any part of thefe great effe€ts was to be attributed to the ftrudture of the arch. Whether it has been, that the fuperior excellence of the Grecian architecture has afforded their genius fo thorough employment, that they have not had leifure to examine, with fufficient accuracy, the works of our anceftors of. the Gothic age; or that their contempt of any thing that could originate amongit Barbarians, as perhaps they concluded of this arch, has produced a negle& of that to which they might other- wife have attended with advantage; certain it is, that few, whether architects or mathematicians, have paid much regard to . this Read Nov. 7s 17896 t- 5644 this fpecies of archite@ture. And thofe who have incidentally made mention of it, have in general dire€ted their enquiries to its origin rather than its principles. 2. The Saxon, Norman and Gothic ftyles of architeQure, though nearly related to each other, yet have their peculiar chara€teriftics and diftinguifhing features, The Saxon and Norman architecture agree in this, that the form of the building is the fame, the pillars round, fquare or polygonal, and very ftrong and maflive, and the arches and heads of the doors and windows femicircular. Mr. Lentham thinks that the criterion of Norman architecture, by which it is diftinguifhed from the Saxon, is its fuperior maflivenefs and enlarged dimenfions. The Saxon churches, he obferves, were often elegant fabrics and well conftruéted, but generally of a moderate fize, frequently completed in the fpace of, five or fix years, or lefs time. The works of the Normans were large, fumptuous and magnificent, of great length and breadth, and carried up to a proportionable height, with two and fometimes three ranges of pillars, one over another, of different dimenfions, conne@ed together by various arches, all femicircular, forming thereby a lower and upper portico, and over them a gallery. In the centre was a lofty tower, and fometimes one or two added at the weft end, as in the venerable cathedral at Hereford, which not long fince has funk under the weight of years. But I am inclined to think there is a much more ftriking difference between thefe two orders: I mean in the pillars. The Saxon columns, we know, were round, fquare or polygonal, and very mafflive ; but if we look’ into Do&or Ducarel’s Norman antiquities, we fhall find the Norman pillars, without exception, to be flender and foe and cluftering. In England, therefore, the buildings, erected) in the time of the Norman princes were in a ftyle compounded of both; to the fimple and primitive Saxon adding the rich decorations and enlarged dimenfions of the Norman ftructure. * The, body or trunk of the pillars. were ufually plain cylinders, or fet off only with fmall half columns united»to them; but, to adorn them, they fometimes ufed the fpiral grove winding round them, and the net or lozenge work overfpreading them.. The capitals were, in general, left plain without any manner of fculpture, though inflances occur, in fome cafes, of foliage and animals on them. As to the arches, though for the moft part plain and fimple, yet fome of their principal ones, as thofe over the chief entrance at the weft end, and others more expofed to view, were abun- dantly charged with peculiar {culpture, as the chevron work or zig-zag moulding ; the embattled frette, the triangular frette, the nail-head, the billeted moulding, ‘and ~the hatchet moulding. To adorn the infide walls below, they had rows of little pillars and arches; and applied them alfo to decorate large vacant {paces in the walls without; they ufed alfo the corbel table ; and the nebule, which was a projection terminating in an undulating line. To thefe marks of the’Saxon and Norman ftyle, we may add, that they had no tabernacles or niches with canopies, or pinnacles, or fpires, or any ftatues to adorn the outfide of their buildings, though fometimes they had miniature relievo figures over the doors. “+ The marks which conftitute the character of what is called the Gothic architeCture, are its projeCting buttreffes, its pinnacles and fpires, large ramified windows, niches, canopies eae and * Bentham’s antiquities of Ely cathedral. + Rious’s architecture. b wed and fculptured faints, the fretted roof, the cluftering pillar, but above all, the pointed arch. And as plainnefs and folidity conftitute the leading features in the Saxon and Norman build- ings, fo, on the other hand, the Gothic archite€ture is diftinguifhed by the lightnefs of its work, the boldnefs of its elevations, and the profufion of its ornaments. So that the Saxon bears fome fimili- tude as it. were to the Tufcan order; the Norman to the Doric and Jonic ; and the Gothic to the Corinthian and Compofite. 3. In our enquiries into the origin of the Gothic ftyle, we meet with not lefs genius and fancy than has been difcovered by the writers on the origin of the Grecian orders, but a much greater diverfity of fentiment, there being not lefs than five different opinions held with regard. to the rife of this f{pecies of architeQure: either that it was introduced from the eaft by the Crufaders, and fhould therefore be ca.'zd Saracenic; or borrowed from the Moors in Spain, and fhould therefore be ftyled Moorefque ; or derived from the ancient cuftom of worfhipping in groves, where the eye being long accuftomed to contemplate the arches formed by the branches of the trees that fhaded their altars, it was natural, when covered buildings fucceded to thefe groves of worfhip, that men fhould endeavour to introduce fome fimilitude between them and thofe places in which they had been accuf- tomed fo long to perform their religious ceremonies; and that ac- cordingly we find not only the arches formed by the branches exa@tly imitated by the pointed arch, but the ftems of the trees as accurately reprefented by the flender and cluftering pillars. The elegance, ingenuity, and plaufibility of this opinion have & [ so] have not failed to procure it the moft general approbation. By others however it is maintained, that this arch originated from the interfeGion of. circular arches in Saxon architelure; and others, laftly, from the like interfeGtion of circular arches in Grecian architeCture. 4. Wutu regard jto the firft opinion, which has been coun- tenanced, or rather firft advanced by Sir Chriftopher Wren, fome weighty objections obvioufly prefent themfelves. And firft; in- fiances may be produced, of the .exiftence of the pointed arch in Europe antecedent to the Crufades. _* Dr. Stukely is of opinion, that the antient fanciuary at Weftminfter, in which the arches were pointed, was built by Edward the Confeffor: “ Neverthelefs,” fays' he, “ I fhall not be ayerfe to think it much older.” o The church of Kirkdale has alfo the pointed arch, and is of the age of the Confeffor. Croyland bridge in Lincolnfhire, which confifts of three) Gothic arches, and is fuppofed to have Fecgi built in honour of the Trinity, is of an earlier date than the Crufades, the time of its. building being determined to be. the year.860. Befides, it does not appear,|.that what we: call the Gothic i is the prevailing ftyle of architefture in) the Eaft; on, the contrary, the ftyle which predominates in that country is a corruption of the Gre- cian. This-is a pointfo univerfally admitted, that Dr. Warburton thaintains, that the Saxon archite@ure, is ‘an imitation of the ne Eaftern. *tArcheol, vol. i. +. See Ledwich on Churches, Archzol. vol. viii. [Moos ol Eaftern. ‘“ When the Saxon kings,” fays he, “ became Chriftian, “ their piety (which was the piety of the times) confifted in “ building churches at home, and performing pilgrimages to the “ Holy-land; and thefe fpiritual exercifes affifted and fupported “one another: For the moft venerable, as the moft elegant mo- “ dels of religious edifices were then in Paleftine. From thefe “our Saxon builders took the whole of their ideas, as may be “ feen by comparing the drawings which travellers have given - “us of the churches yet fianding in that country with the “ Saxon remains of what we find’ at home. Now the architec! “ ture of the Holy-land was entirely Grecian, but greatly fallen “ from its antient elegance. “r? Ste 7 Pope's Effays, vol. 3, Ep. 4. And Mr. Ledwich, in his learned’ effay on’ the architeQure of our Englith churches, advances very ingenious atywalenes to fhew that the Saxon flylé had an Eaftern origin, ‘and produces a ftriking inftance from ‘a Syriac MS. | of “the Evangelifts, written A: D. 586, preferved in the Medico-Laurentian library at Florence, which contains drawings of arches ornamented with’ every cha- racteriftic of, the Saxon ftyle. * Cornelius Le Brun has publithed many views of Eaftern buildings, ‘particularly of thofe in the Holy-land ; and in all’ thefe only one Gothic ruin, the church near Acre, and a few pointed ‘arches occur, and thefe were built” by the Chriftians when in poffeffion of the country. In Sales Koran, the temple of Mecca is reprefented as built with femi- circular not pointed arches. Neither did Pocock, Norden, or Shaw difcover any traces of this ftyle, as far as we can argue from * Grofe’s Antiquities, Pref. bear) from the drafts which they have given us in their travels. It appears therefore, that there is little or no reafon for fuppofing our Gothic buildings imitations. of the Eaftern;, for although the pointed arch may in fome few places occur, yet it by no means is the charaCteriftic of the Eaftern ftyle. 5- Tue fecond opinion, that the Gothic archite@ture was derived from the Moors, who introduced it with their victo- rious arms into Spain, froma whence it was imported into the other countries of Europe, appears to be lefs tenable than the firft; the form and decorations of the Moorifh arch being very different from. the Gothic, as may be feen in the drawings which are given us of Moorifh buildings, particularly of the celebrated palace of Alhambra.. See Swinburne’s travels in Spain. See alfo in Houel’s Picturefque Voyage through the iflands of Sicily, Malta and Lipari, a drawing of the prince of Palagonia’s palace at La Bagaria, which is a Moorifh building. Neither are there the leaft traces of Gothic archite@ure in the drawings of the Moorifh. palaces in Les Delices d’Efpagne *. In all thefe, and alfo in the Moorith caftle of Gibraltar, the arches are either femicircles, or fegments greater than femicircles, approaching to the horfe-fhoe’ form, which is the: genuine Moorifh arch. 6. Tuer third opinion is that of Dr. Stukely, “ The original * of all arts,” fays he,“ is deduced from nature; and affuredly “* the idea of this Arabian arch, (fo he calls the Gothic) and flender- * Grofe’s Antiquities, Pref. [ 62 ] * flender pillar, is taken from the groves facred to religion, of “ which the great patriarch Abraham was the inventor.” This hypothefis was adopted by Dr. Warburton, who has fet it forth to full advantage in his notes on. Pope’s Effays. See Ep. 4. Againft which however there lie fome objections that do not admit of very obvious anfwers. ft, Wuen worfhipping in buildings of wood and ftone fuc- ceeded to the cuftom of worfhipping in groves, if the fafhion of thefe buildings had been fuggefted by the images prefented in groves, as this opinion fuppofes, then the moft ancient ftyle of religious buildings would have been Gothic. But this is con- tradicted by fact, for in the Eaft, where worfhipping in groves firft prevailed, the architeQure is not of this primitive {pecies, but is a corruption of the Grecian, in which the circular form of the arch is retained. And it is a known truth, that the moft ancient religious buildings, of which we have any account, were not in that ftyle which is called Gothic. But if fo, this hypo- thefis muft be abandoned; for it is wnreafonable to fuppofe, that the arches in the firft religious buildings which immediately fuc- ceeded the period of worthiping in groves, fhould not bear any re- femblance to thofe which are reprefented by the interlacing branches of trees, when the minds of the archite&ts were fo ftrongly im- preffed with the images of thofe « Leafy Cathedrals,” and yet, that the form of the arches, which were introduced ages after that cuftom, and all its concomitant fcenery had funk into utter oblivion, fhould be derived from them. adly, ao 8 adly, Tuoucn it fhould be granted, that the origin of Gothic architeCture was derived from the cuftom of worfhiping in groves, yet there does not appear to be any reafon why this ftyle fhould therefore be introduced into military architeQure. Yet we find, in fa&t, that, in England at leaft, it has been intraduced into military perhaps as early as into religious buildings. Edgar’s tower at Worcefter, which is in the Gothic ftyle, was the portal into the Saxon citadel, and was erected in the reign of Ethelred, the fe-. cond fon of Edgar, anno roos, as appeared from an ancient infcription on a {tone in the building which was taken down a few years ago: the infcription may be feen in Mr. Green’s hiftory of that city. Door Littleton, dean of Exeter, in a differtation. read before the fociety of Antiquarians in 1757, has indeed ven- tured to affirm, that this tower is not older than the time of King John, on the authority of Mr. Habington; who fays, “ that in * all likelyhood, the figure of the King with croffed legs reprefents “ King John, who, anno 121s, took on him the fign of the crofs * for the holy voyage; or King Richard the rft, whofe lyon’s “« heart fo conquered the infidels.” But he takes no notice, as is obferved in Grofe, of the female figures on each fide of the King,. nor of the date. And as both thefe kings had each but one wife,. the dean believes the figure really reprefents King Edgar, and the two female figures Ethelfleda and Ethelfrida. But if this be ad- mitted, it feems to follow, that it muft be of the antiquity which the date implied ; for it is highly improbable, that in the reign of one of the Norman princes, a tower fhould be erected to the honour of a Saxon king, who had died two hundred and fifty years before. But whether this building be altogether of as ancient a date L 64 a date as is afferted, or not, it is evident that the introdu@ion of this arch into military buildings could not have arifen from any defire of imitating the original fcenes of religious worfhip; it muft therefore have taken its rife cither from a fuppofition of its fupe- rior ftrength, beauty, or other peculiar advantages: And _ this being once admitted, there is immediately affigned a more pro- bable and fufficient reafon for its introguCtion into religious archi- te€ture alfo. 3dly, One of the principal arguments in favour of Doétor Stukely’s opinion is, that the Gothic flyle comprehends not only the pointed arch but the flender and cluftering pillar alfo; the one reprefenting the ftems of the trees, the other the arches formed by the interfeCtion of their boughs. “ Could the arches be other- “ wife than pointed,” fays Do€tor Warburton, “ when the work- “ man was to imitate that curve which branches make by their “ interfeGion with one another? Or could the columns be other- “ wife than fplit into diftin@ thafts, when they were to reprefent “ the ftems of a groupe of trees?’ But this argument overturns the hypothefis in confirmation of which it is advanced; for on this fuppofition the flender and cluftering pillar fhould be of the fame date with thé pomted arch; and they fhould have been in- feparable companions in art as they are in nature, of which it is pretended, that this ftyle is a clofe copy. Now we know, that the pointed arch when firft introduced into England, was not fupported on flender pillars, but on the maflive columns of the Saxon order, which were in fafhion at tlat time; and afterwards on the flender fluted pillars of the Normans, which were at length fplit into [ 65 ] into diftin@ thafts, at a moreeadvanced period of the Gothic ftyle. So that, in England at leaft, the pointed arch and cluftering pil- lar have had different originals and periods of introdu@tion. This obfervation feems to me effetually to overturn the hypothefis we are at prefent examining, one main part of the fancied fimilitude be- tween Gothic, archite@ure, and the ancient fcenes of religious worfhip, being thus proved to have fprung from a different fource. 4thly, If the pointed arch had been intended to refemble arcades formed by the branches of trees, we mutt fuppofe, that the ornaments of that arch would have had a clofe affinity to their original. But on the contrary we find, that leaves or foliage conftitute but an occafional and accidental, not an effential part of the Gothic ornaments. 7- Tue fourth opinion on this fubje@ is, that the Gothic arch has probably taken its rife from thofe arcades we fee in the early Saxon and Norman buildings, where the wide femicircular arches ‘conneting the alternate pilafters, crofs and interfe@ each other, and form at their interfeGion a narrow and fharp pointed arch. But there does not appear fufficient grounds for our attributing the origin of this, arch in general to the interfeQion of Saxon circles’; for! if! fo, the Gothic ‘archite@ture would have hada Saxon original: but we find it in countries where no other traces “of the Saxon. ftyle occur... Thus the pointed arch difcovers itfelf amongft the Moorifh arches in the famous palace of Alhambra , and not only the pointed arch but fluted pillar alfo is to be found K in E , 60:.9 in the church of St. Mamas, at Morfou, in the ifland of Cyprus. See Drummond’s travels. Georgio Vafari, in his proem to the lives of the Painters, fays, that in the time of Theodoric, (that is, about the year 500) the architeCture in Italy was of that man- ner called Tedefco or Teutonic*. And the baptiftery at Pifa, built in the year 1063, was fubfequent to the period of Gothic archi- teGture in that country, in which, though built in the Grecian ftyle, we yet difcover evident traces of the Gothic, which was now giving way to a better fafhion: But, at that period, we are certain, that the archite@ture in England was not Gothic. And as we find the ufe of the pointed arch in countries fo widely diftant, we muft look for fome more general principle of its introduction than the interfe@tion of Saxon arches. 8. THE * After {peaking of the five Grecian orders, he thus defcribes the ftyle which he calls Tedefco: «* There is another fpecies of architeture called Tedefco, which in its orna- ments and proportions is very different from the antique and from the modern; nor is it ufed at prefent by good architeéts, but is avoided as barbarous and monftrous ; being entirely deficient in order, fo that it may be rather called diforder and confufion. The doors are ornamented with flender pillars, and twifted like vines; which can- not have ftrength to fuftain a weight, however light it may be. And thus by all their mouldings and other ornaments, they made a jumble of tabernacles one upon another, with fo many pyramids, and points, and leaves, that they are not only unable to fuftain a weight, but fcarcely even to ftand; and they have more the appearance of being made of cards, than of ftones and marble. And in thefe works they made fo many fudden tranfitions, breaks, little brackets, and turns, that they marred the proportion of their works; and often went to fuch a height, that the top of the door touched the roof. This manner was invented by the Goths, who, after they had deftroyed the ancient fabrics, and the architects were flain in war, introduced the arches of the fourth point, and filled all Italy with this monftrous ftyle of building.” Vafarts Lives of the Painters and Architetts, vol, i. p. 65. [ oT 8. Tue fifth opinion is that which has been given by Mr. Barry, in his very ingeniousand elegant Enguiry into the real and imaginary obftructions to the arts in England, where he endeavours to fhew us the fucceffive corruptions of architefture, as they grew out of one another, by which it was led infenfibly from the Grecian to the Gothic tafte. “ There are at the dome of Viterbo,” fays he, “ and at St. Mark’s, Venice, ranges of columns, from “ which regular arches, of half a circle, interfe@ one another, ““ by being made to fpring from every third column, which gives “ a Gothic arch between every two.’ And he farther adds, that before the great nich, which has been cut through the attic of the pantheon, there are two columns which are remarkable, as the flutes are more than a diameter of a circle deep. ‘This outrayed a little, by finking the flutes deeper, and leffening their number, he thinks, led to the Gothic bundle of columns. Tuat the Saxon, Gothic, Moorifh and Eaftern ftyles of build- ing are but various corruptions of the Grecian, feems evident: The fimilar divifion of the column into pedeftal, fhaft, and ca- pital, the imperfect acanthus, and the faint traces of the Ionic volute which we fometimes meet with, will not fuffer us to doubt of this; but that the Gothic arch derived its origin from the identical circumftance in Grecian. architeture here pointed out, feems by no means fufficiently evident. For St. Mark’s, Venice, according to the teftimony of Vafari, was built towards the conclufion, not commencement of the period of corrupt archi- te€ture. So that if the pointed arch was indeed fuggefted in this manner, which however is extremely uncertain, it muft rather K 2 “ have Lom have been derived from the church of St. Sophia at Conftantino- ple, which was built in the 20th of Conftantine, that is, in the year 344, and was the original from which the plan of St. Mark’s, Venice, was taken. Although the Gothic archite€ture commenced fo early amongft the Goths and Longobards, and that the true tafte began to revive about the year 973, yet attachment to inveterate cuftoms and the beauty of the ftyle itfelf prevented it from falling into entire difufe for fome centuries after ; according to the obfervation of Pira- nefi, in his work Della magnificenza d’architettura de’ Romani, “ la Greca (architettura) poi non poté effer portata in Egitto, fe non fotto il regno de’ Tolommei: quantunque per altro, fic- “ come difficilmente ci diftacchiamo dai coftumi inveterati, é “‘ cofa piu probabile, che a que’ tempi fi confondeffe luna coll’ “ altra, di quel che l’Egizia foffe affatto pofta in difufo. In quella guifa appunto che noi vediamo la chiefa di S. Agoftino, tanto “ tempo dopo effere ftati fcacciati d'Italia i Goti e i Longobardi, cioé anno 1483 di Crifto, effere ftata fatta alla Greca, e in- fieme di quell forma ftraniera, la quale era ftata in ufo in Italia per tanto tempo.” We are further to obferve, that when it is faid, that the deepening of the flutes in the Grecian columns led to the Gothic cluftering pillar, it is not neceffary to fuppofe, that the Gothic ftyle, in this refpe&, was dire€tly derived from the pure Grecian, without paffing through any intermediate grada- tions. In England it is more than probable that the fluted co- lumn, and its offspring the cluftcring pillar, was of Norman defcent, as may be conjectured from the drawings of Dodtor Ducarel ; which Norman ftyle, we muft allow, was but a cor- ruption of the Grecian, thus at length propagated into England. And oe ee [ 6 ] And that we, of thefe countries, are not in any wife indebted to the Norman builders for the pointed arch itfelf, cannot I think be very pofitively afferted, when we confider that the win- dows of the palace of William the conqueror at Caen were all pointed. So that although the pointed arch might have exifted in England prior to this period, yet it was not till after the Nor-- man conqueft that it became the prevailing fafhion. This cir- cumftance of the turn of the arches in the palace at Caen Dr. Ducarel feems to have forgot when he tells us, * page 102, that the pointed arches were not introduced till near the end of the twelfth century. Italy has long been the fchool for the fine arts, and as the Gothic architecture, from the teftimony of Vafari, feems firft to have originated’ there, it is probable, that archite@s bringing home with them from thence the idea of the pointed arch, it affumed in different countries the garb of that into which: it had been admitted. Thus the Gothic buildings in Germany, England, Spain, though they agree in the form of the arches, differ widely in their decorations. “ Tuere iffued from the hands of the mafters of thofe times,” fays Vafari, “ thofe fantaftical and rude things which appear, even “ at this day, in what remains of their works. The fame thing “ happened in architeCture, for ‘it being neceffary to build, and “ the form and good manner being entirely loft by the death of “ the artifts, and the deftrution of their works, they who gave “* themfelves up to fuch ftudies, did not build any thing which for “ order * See his Norman Antiquities. a c [ol order or meafure had grace, either in the defign or in any pro- *‘ portions. Whence new archite@ts arofe, who from their barba- tous notions produced that manner of building which by us is now called Tedefco, who did fome things which afforded rather a fubje& of laughter to the moderns, than praife to them; until afterwards better archite€ts found out a better form, and fomewhat like unto the good antique. In this ftyle are the oldeft churches in Italy, but not antique, which were built by them, as by Theodoric, King of Italy, a palace in Ravenna, one in Pavia, and another in Modena, but in the barbarous man- ner, and rather rich and large, than well defigned or of good architeQure. The like may be faid of St. Stephen’s in Rimini, of St. Martin’s in Ravenna, and of the temple of St. John the Evangelift, built in the fame city about the year of our falva- tion 438; of St. Vitale, which was built in the year 547, and, in fine, of many other monafteries and temples built after the Longobards. All which buildings, as has been faid, are great and magnificent, but of moft incorreé architeQure,; and amongft thefe are many abbies in France, built to St. Benedetto; and the church and monaftery of Mount Cafino; the temple of John the Baptift at Monza, built by that Theodolinda, queen of the Goths, to whom Pope Gregory wrote his dialogues; in which place fhe caufed to be painted the ftory of the Longo- bards, Afterwards, in Florence, architecture recovering a little, the church of the Holy Apoftle, which was built by Charlemagne, though fmall, was in a very beautiful manner. The archite€ture of this church was fuch, that Pippo di Ser Brunnellefco did not difdain to make ufe of it as a model for the church of the “ Holy [Rey Holy Ghoft, and that of St. Lorenzo in the fame city. The fame may be feen in St. Mark’s, Venice, which was begun under the Doge Juftinian, and finifhed in the Grecian manner in the year 973. And thus things went on till the year 1140. In the fame Greek manner, and at the fame time, were the feven abbies, which the Count Hugo, Marquis of Branden- burgh, caufed to be made in Tufcany; and other buildings, which fhew, that architecture kept its ground a little, but much corrupted, and very different from the good ancient manner; of which many old palaces bear teftimony, built in Florence, after the ruin of Fefole, of Tufcan workmanfhip, but in the barbarous ftyle, in the meafure of the doors, and very long windows, and in the curviture of the fharp arches of the fourth point, in the turn of the arches, according to the practice of the ftrange archite@ts of thofe times. After- wards in the year ror3 the art feems to have recovered its vigor a little; in the rebuilding of the beautiful church of St. Miniato, in which it appears, that the Tufcan artifts en- deavoured to imitate in the doors, windows, columns, arches, cornices, as much as they could, the good ancient order, &c.” have been thus full in this extra@ from Vafari, as he is fo exprefs as to the period and manner in which this Gothic ftyle of building firft originated, and is fo competent a judge of fuch- a fubjed. Mr. Lepwicu indeed, in the effay above referred to, is of opinion, that the Gothic arch had been known and ufed many centuries before the Gothic power was eftablifhed. But the two inftances. [ areal inftances which he produces, as he himfelf obferves, are not per- fe@tly Gothic, but thofe arches called contrafted, which have never been afcribed to the Goths and Longobards: and we are further to obferve, that they are not fuppofed to reprefent an actual building, but the ornaments of a cibarium only, = But in truth it feems extremely nugatory and fruitlefs to endeavour to afcertain the fpecific accident which gave birth to the pointed arch; many, almoft innumerable different circum- ftances could be affigned from which it might have originated ; andswho would venture confidently to adopt one in exclufion of the re{t?. One may, perhaps, appear more probable than another ; but difcoveries do not always arife from thofe circumftances, which after they have been made, might have been fuppofed moft naturally to have led to them. Who, for inftance, after ftudying the works of Newton, could have conjectured, that his great theory of the univerfal gravitation of matter had been fuggefted by the falling of an apple from a tree ?>—The mind indeed may fome- times amufe itfelf with excurfions into the aerial regions of fancy and conjecture; but to find reft, it muft return to the firm ground of fact. However entertaining therefore our fpeculations may be on the poffible caufes which gave rife to the idea of the. Gothic arch, we can be faid to reafon only when we direct our enquiries to the actual properties of the arch, which might have recommended its introduction into archite€ture, after the fafhion of fuch an arch had been conceived. In other cafes, as in the circle, ellipfe, and catena- ria, the nature of the curve alone is fuppofed fufficient for that pur- pofe; why then in the Gothic arch are all thefe confiderations to be “ paffed fF ggad] paffed over? Certainly if it be poffeffed of any peculiar advantages, it feems unreafonable to fuppofe, that they were entirelyun known or difregarded; and that it is really poffeffed of fuch, or at leaft has been fuppofed to be fo, which is fufficient in the prefent cafe, we may conclude from what has been faid by Monf. Gautier on this fubje@, in his Traité des Ponts et des Chemins ; “ The Goths,” fays he, ‘“* who fucceeded the good tafte of the Roman architecture, “ erected bridges in many parts of France with pointed arches, “ defigning by that means to diminifh the lateral preffure, both “in public and private buildings, and alfo in the churches of “ that period, which ftill remain.” And Sir Chriftopher Wren obferves, “ that the fharp-headed arch rifes with little centering, “ requires lighter key-ftones, and lefs butment, and yet will “ bear another row of double arches rifing from the key-ftone.” The idea of the pointed arch might indeed have been firft fug- gefted in the manner defcribed by Mr. Barry, or perhaps by the perfpeftive of groin arches; but the mere conception of fuch a form, would not, I fhould imagine, have been a fufficient mo- tive with architeéts to introduce it into their moft magnificent buildings, and where it was to fuftain the greateft weights. I fhall therefore now proceed to enquire into the theory of this arch, and endeavour to afcertain its relative ftrength as compared with circular and elliptic arches, when in a ftate of perfect equili- bration; and alfo to determine the aberration from a true ba- lance, which is generated by the horizontal. termination of the folid building ere&ted on it; from whence we fhall be enabled to form fome conjeéture, whether the theory of the arch itfelf L may E par may not be juftly enumerated amongft the caufes, to which we owe its introduction into architecture, g. THE equilibration of arches, which has been fo well treated of by Mr. Emerfon in his E/ffay on the Conftruétion of Arches, and Mr. Hutton in his Effay on Bridges, may be afcertained in a very fimple manner, by confidering the vouffoirs, or arch-ftones, as fo many wedges urged by the incumbent weight, and endea- vouring to fplit the arch. Now the efficacy of a wedge depends on the magnitude of its vertical angle, the impelling force, and the refiftance to be overcome. On the firft account the force of the vouffoir, confidered as a wedge, at any point of the arch, is dire€ily as the radius of curvature of the arch at that point; on the fecond account, it is as the fquare of the fine of the angle formed by the tangent to the curve, at the given point, with a vertical line ; and on the third account, it is directly as the fine of the fame angle. to. Tue materials of which arches are compofed are fuppofed to be of the fame magnitude; and the joints of the ftones muft always be perpendicular to the curve, for every force acting againft a furface ats in lines perpendicular to it; and therefore the force of the incumbent weight to rend the curve is to be refolved into two, one of which muft be perpendicular to the curve, and the other, of confequence, in the direction of the tangent: now if this latter force were not perpendicular to the joints, that is, if the joints were not perpendicular to the curve, there would arife a lateral [ ms a a lateral preffure, whofe direQion would not be along the tangent, and wanting a force to fuftain it, would deftroy the equilibrium, Let EABF, 7, mut, reprefent two concentrical femicircles: alfo let AB, mm, be two vouffoirs fimilarly fituated, whofe fides, being perpendicular to the curves, converge in the centre C: the forces of thefe vouffoirs, confidered as wedges, are inverfely as the fines of their vertical angles, that is, becaufe of the equality of the arches, dire€tly as the radii of curvature: And the like holds in any other curves whatfoever. 11, Acatn, let H&A be the invariable breadth of the vouffoir, and Gg HA the incumbent weight; this weight, becaufe the alti- tude G/ is fuppofed given, is dire&ly as the breadth 4 & of the in- cumbent column; that is, if 4H be confidered as radius, direClly as the fine of the angle H4, formed by the tangent at the point H with the vertical line gH: but the force of this entire weight muft be refolved into two, one g¢ K in the direCtion of the tangent, the other HK perpendicular to the curve, which is the force im- pelling the vouffoir to fplit the arch; and the line HK, which reprefents this latter force, becaufe gH is given, is the fine of the angle Hg K, which isequal to that formed by the tangent at H with the vertical line. Hence therefore, conjoining both thefe ratios, the force impelling the vouffoir is as the fquare of the fine of the angle formed by the tangent to the curve, at the given point, with the vertical line. 12. Acain, the wedge, impelled in a direftion perpendicular to the curve, endeavours to fplit the arch, and therefore move L 2 one Fig. 1 ee! one fegment about the fulcrum 7, and the other about the fulcrum ¢; and therefore the force of the vouffoir, acting on the levers Hz, H 7, is dire@ly as the perpendiculars ¢p, rg, let fall from the fulcrums on the line of direG@ion Hg, that is, dire&tly as the fine of the angle ¢Cp, or Hg K. \ 13. Hence therefore if a weight, like a wall, be incumbent on the arch EABF, ftanding in a vertical plane, if the height of the wall on any point be in a ratio compounded of the recipro- cal triplicate ratio of the fine of the angle formed by the curve and vertical line, and the reciprocal fimple ratio of the radius of curvature in that point, all the vouffoirs will endeavour to fplit the arch with equal forces, and therefore will be in perfec equilibrium with each other. On this general propofition depends the theory of the conftruction of arches. 14. Burt fince the materials with which arches are conftructed are not of infinite ftrength, there muft be a certain degree of preffure, which will rend even an arch whofe parts are in perfect equilibrium. Now the ftrength of an arch, in its different points, is as the greateft weight which it is able to bear on thofe points without breaking; that is, in a ratio compounded of the reci- procal triplicate ratio of the fine of the angle formed by the curve and vertical line in its different points, and the reciprocal fimple ratio of the radius of curvature in the fame points, On this principle the comparative ftrength as well of different arches as of the fame arch in its different points may be eafily afcer- tained. 15. Let L PR 15: Let BD, confidered as variable, reprefent the fpan of Mig. 2. the Gothic arch BED, fpringing from the points B,D; and the invariable line-C D the radius of the circle by which the Gothic arch is defcribed. On BD defcribe the femicircle BHD; the ftrength of the femicircular arch BHD at H is to the ftrength of the femicircular arch AGD at G, as CD to KD, by Art. 1o.. But, fince the relative ftrength of arches is to be determined by comparing them in their weakeft points, (for if an arch fails in any one point, the whole falls to ruin) the ftrength of the femicircular arch AGD will be to the ftrength of the Gothic arch, as the ftrength of the femicircle at G to its ftrength at E, that is, as the greateft weights thefe points are able to bear when in equilibrium ; that is, reciprocally as the cube of the angle IE F contained by the vertical line TE and the tangent to the circle at E, or its equal EC K, that is, as the cube of EK to thecube of radius, Art. 14. Therefore, ex equo, &e. the ftrength of the femicircular arch BHD at H, is to the ftrength of the Gothic arch of the fame fpan, defcribed with the radius CD, as GCXEK? to KDxGC3, or as EKX AK to C D?. 16. Since the re€tangle EKxAK _ vanifhes at both extre- mities when K arrives cither at A or D, there muft be fome intermediate ftate where it is a maximum; to find this ftate, let CD=a, and CK=x; EK=a@’~x"), and AK=a+.», therefore L Wag therefore the re@angle EKx AK= ae Xadx ; whofe fluxion ait ita? XN —axx That is, the rectangle E K x AK isa maximum, when CK=3CD: or, becaufe C D isconftant, the ratio of the ftrength of a femicircular =o. Whence x*+3a~ =5a?, and x=Faz. = x q@i—x7 arch to a Gothic arch of the fame fpan is greateft when the fub- tenfe of half the Gothic arch is equal to its fpan. In this cafe the ftrength of the femicircular arch is to the ftrength of the Gothic as 1299 to 1000, or 13 to Io, nearly. Ir the radius of the Gothic arch be three-fourths of the fpan, in which cafe it is called the fharp arch of the fourth point, the ftrength of a femicircle will be to the ftrength of a Gothic arch of the fame fpan as 1257 to rooo. And if the radius be two-thirds of the fpan, in. which cafe it is called the fharp arch of the third’ point, the ftrength of the femicircle will be to the ftrength of the Gothic arch of equal fpan as 1210 to 1000. 17. Because the rectangle E K x AK exceeds the fquare of the femidiameter when the point K bife€&ts C D, and vanifhes when K arrives at D, there muft be fome intermediate pofition, in which the reétangle EK x AK is equal to the fquare of radius. To find the magnitude of K D in this cafe, let C K=7, and. Cp=2 as before; then EK =/a?—x*, and AK=a+»; therefore a+-xxXVa@—x?=a", and x*+2ax3-2a3x=0; and if a=1, x?+2x?=2. Of this equation two roots are impoflible: The third, E yo J third, or CK = 839286755214, &c. That is, if the radius of the circle, by which a Gothic arch is defcribed, be to the interval of the capitals from which it fprings, as 1 to ,321426489572, the Gothic and femicircular arch of equal fpan will be alfo of equal ftrength. 18. Hence therefore, a Gothic arch whofe radius of curvature is equal to the interval between the pillars, which is the ufual man- ner of defcription, is the weakeft of all Gothic arches of that fpan. According as the centre from which it is defcribed moves on either fide, in an horizontal line, the ftrength of the arch increafes: if it moves towards the middle point of the interval of the pillars, the ftrength increafes till the centre arrives at K, when the Gothic arch becomes. a femicircle. But if the centre moves in the contrary direction, the ftrength of the arch in- creafes without limit. 19. Mons. Gautier therefore is too general in his affertion when he fays, that the Gothic arch is ftronger than the femi- circle; as this is true only in certain cafes, to wit, when the radius by which it is defcribed exceeds the fpan in the ratio of 1 to 1321426489572, very nearly; in all other cafes it is weaker. We may obferve alfo, that Sir Henry Wotton is not fufficiently . warranted in his cenfure of this arch, when he fays, that “ thefe ‘« kind of arches, both for the natural imbecility of the acute angles, “ as likewife for their uncomelinefs, ought to be exiled from all “« judicious eyes, and left to their firft inventors, the Goths and “« Lombards, amongft other reliques of the barbarous age.” As to its. Fig. 3. ¢ L oad its beauty or deformity, it being a matter not fubje@ to mathe- matical argument, his eriticifm on that head cannot be brought to the like decifive teft 23 the former, and therefore we fhall not pretend to controvert it. u 20. Tue depreffed or fcheme Gothic arch is deieabed from centres, lying below the right line joining the capitals of the pillars from which it fprings: thus the arch BF D is defcribed from the centres m, 2, which lie below the horizontal line BD. Its ftrength is eafily computed by continuing the arch FD to the horizontal line RS which paffes through the centres m, #: and then, proceeding as before, the ftrength of the Gothic arch BFD will be to the ftrength of a femicircular arch of equal fpan, as FG3x KD to mS¢, that is, becaufe both FG and KD muft always be lefs than mS, in a ratio of lefs inequality. And the ftrength of the two Gothic arches BE D, BF D will be to each other in the dire@ duplicate ratio of their radii of curvature, and the inverfe triplicate ratio of the perpendicular heights of the arches above the lines of their centres. The ftrength alfo of the Gothic ,arch of four centres may be eftimated in the fame mannet. 21. But as the buildings ere€ted on Gothic and femicircular arches are never fo formed as to render them curves of perfe@ equilibration, but are generally terminated by an horizontal right line, it will be neceffary to compare them in this refpe@ ; and we fhall find, that though the ftrength of the Gothic arch, when in equilibrio, [ er ] equilibrio, is in certain cafes greater than that of a femicircular arch of equal fpan, yet a given altitude of folid building ereéted on the Gothic will in fome cafes, but not in all, produce a greater aberration from a perfet equilibrium than in the femicircular. Let BNED, BHD, be the Gothic and femicircular arches, whofe common fpan is BD; let GR reprefent indifferently the ex- tradoffo of either, Poi which let fall the perpendicular GM on the fpan, meeting the curves in N, 2; and let a be the altitude of the folid building erected on each. If the Gothic arch were in perfect equilibrium, the height above N would be to a, as EK3 “to NM:; and the height above m in the circle would be to the fame a as HK? tom M3 (Art. 13.).. Now if an ellipfe were defcribed with B D as a minor axis, and with E K asa femitranfverfe, it would fall without the Gothic arch, and meet the perpendicular GM fomewhere between N and G, for the radius of the circle ofcu- lating the ellipfe in B is equal to aie (Ham. Con. Prop. 17. L. 5.) that is, equal to the greater abfciffa of the circle B NE, and there- fore greater than the radius of the Gothic arch; and the ofculating circle falls without the ellipfe (Ham.Con. Prop. 15.L.5.); but fince the ofculating circle touches the ellipfe fo intimately, that no circle can pafs between it and the ellipfe, the Gothic arch muft fall within it; therefore the ratio of EK to NM is greater than the ratio of EK to mM, that is, than the ratio of HK tonM (Prop. 30. L. 1. Ham. Con.) ; therefore the height of the folid wall over N, in the Gothic arch, muft be greater than over z, in the circle; and confequently, when the line bounding the wall. is not the extradoffo of equilibrium but an horizontal line, there will be a M greater Fig. 4. E Saad greater deviation from a perfect balance in the Gothic arch. But the higher the Gothic arch the lefs will be the aberration ; and it may, at length, be fo far diminifhed as to become lefs than the error in the femicircle, for the ordinates EK, NM, vary in the fubduplicate ratio of their greater abfciffe,; and thefe abfcifiz, their difference MK being given, approach to- wards equality, as the radius of the circle or height of the arch increafes; but the ratio of HK to 2M is the limit of their variable ratio; fo that though the height of the wall to be erected over the correfponding points in the Gothic and femicircular arch, in order to render them curves of equilibration, continually approach to equality, and can be brought nearer to an actual equality, by elevating the point of the Gothic arch, than by any affignable difference, yet the height of the building to be erected on the points of the Gothic arch will always be greater than in the femicircle. Now asE 4, the difference between the ordinates N M, EK, is always greater than Ez, the difference between the ordinates mM, EK, and thefe are always in the conftant ratio of xM to HK, it follows, that by producing the ordinates mM, EK, their difference may be made greater than any affignable quantity; and at the fame time the difference be- tween the heights of the building to be erected on the points N, 2, of the Gothic and femicircular arch, may be made lefs than any aflignable quantity. It is evident therefore, that the defe& of equilibrium over the point N, in the Gothic arch, may be made lefs than the defe& over the correfponding point a of the femicircle, arifing from the horizontal termination of the building erected on them. Thus let the difference of the heights of the wall f°: 8g wall over 2 and N, when the arches are in equilibrium, be equal to d; if Hv be to Hv +d, as HK to KE, Hv will be equal to Er-d. Then a being the altitude of the building over the crown of both arches, and Ng the height over the point # in the femicircle, when truly balanced, the defect of equilibrium in the Gothic arch will be Ng + d-a-Ef, and in the femicircle it will be Ng-a-Hv=Ng+d4-a-Er; but E p is greater than Ev, and therefore the defe€t of equilibrium in the Gothic arch is lefs than in the femicircle. If Er be too fmall, produce EK tillEr-Hv = d, which is greater than 4, the difference of heights when EK is fo produced: then, @ fortiori, the deviation from a perfe& balance will be lefs in the Gothic arch, as before. In all cafes the aberration will be lefs when the altitude over the crown of the arch is lefs; becaufe, when quantities are in a given ratio, the lefs the quantities themfelves are, the lefs will be their difference. And therefore, when the height of the building above the {pring of the arch is given, the higher the arch the more it approaches to a perfect balance. Hence we may obferve, that this arch was peculiarly adapted to the ftyle of thofe religious buildings, which were in fafhion in. the middle ages, where the roof was to be raifed to an extraordinary height, and no great weight immediately incumbent on the. point of the arch, or where one tier of arches was to be raifed over another. But when a very high building is to be ere@ed upon a Gothic arch, the quantity of matter over the crown or vertex muft be very much lightened _ by windows or other perforations, as was the practice with the Gothic architeds.

EK? therefore the ftrength of the fegment of the circle is to the! ftrength of the femi-elliptic arch’ as 2K D* to EK? +4 KD}, that is, always in a ratio of greater inequality. If to this we add, that the aberration from a perfect equi- librium ‘in the femi-ellipfe, arifing from the herizontab termination of the building erected ‘on it, is very great, but of no great confequence in‘ any fegment ofa circle which contains lefs than 120°, (fee Hutton’s Efiay on Bridges,) per- haps it may feem reafonable to conclude, that portions of circles are in all cafes preferable to femi-elliptic arches, or thofe curves of many centres, which of late spare become fo fafhionable in the conftruétion of bridges. In the celebrated bridge the Sein, at Neuilly near Paris, confifting of five arches, each 120 feet opening, and rifing but 30 feet, the radius of curvature at the crown of the arch is 150 feet, and therefore is to the radius of a circular arch of the fame fpan, and rifing only to the fame height, as 2 to 1; and confequently the relative ftrength of thefe arches, without taking into account the enormous error from a true equilibrium in the » and the radius of the circle ofculating the ellipfe in D is former, is in the reciprocal ratio of thefe numbers. And the ftrength of a femi- ellipfe of the fame {pan and altitude is to the ftrength of the curve ufed in the bridge of Neuilly as § to 4. A The radius of curvature of a circle ofculating the vulgar cycloid at its vertex is equal to twice the diameter of the generating circle; and the radius of a fegment of a circle of the fame opening and height is equal to the fum of the fquares of half the circumference and diameter applied to twice the diameter; therefore a cycloid is weaker than a circular arch of the fame fpan and height in the ratio of 11 to 16 nearly. ‘To'this we may add, that the accurate, conftruction of cycloidal arches, in ftone, is almoft impracticable, and therefore a confiderable deduction fhould be made from their ftrength, on account of their imperfect exceution. For thefe rea- fons arches of this kind are not introduced into practice; though Drummond, in his trayels, tells us, that thofe of the bridge of the Holy Trinity, over the Arno, at Florence, are cycloidal. And indeed what is related of that bridge is confiftent with theory, for on account of its extreme weaknefs, it is found neceffary to prevent! wagons and other heavy carriages from paffing over it. [ 85 J ftones (by Art. 14.); that is, as the femidiameter of the ellipfe which is perpendicular to the horizon to the femidiameter of the circle, (Prop. 17. L. 5. Ham. Con.) or as the height of the ellipfe to the height of the femicircle; that is, if BmED bean elliptic arch, its ftrength will be to that of the femicircle BHD, as EK to KD; but the ftrength of the femicircle is to the ftrength of the Gothic arch BED as EK x AK to CD’; therefore, ex @quo, Sc. the ftrength of the elliptic arch is to ie aha of the Gothic arch of equal height and fpan as EK’ x AK, or AK*xKD to CD*x KD, or as AK* to CD’, or in the du- _plicate ratio of the fum of radius and the cofine of the Gothic arch to radius, that is, in a ratio of greater inequality. And fince KD is conftant, AK increafes in a higher proportion than CD; therefore in ‘the elliptic arch, the ftrength increafes in a higher proportion, as the altitude increafes, than in the Gothic. Thus in an elliptic and Gothic arch in which the heights and {pans are equal, and the fubtenfes of their halves equal to the fpan, the ftrength of the elliptic will be to that of the Gothic as 223 toro. And when the ftrength of the Gothic arch, is equal to that of a femicircle of equal {pan, the ftrength of an elliptic arch of equal height and fpan exceeds it nearly in the ratio of 5 to 2 by Art.

Confequently when the altitude over the vertex of the arch is given, and the termination of the wall horizontal, there will be a lefs deviation from a true balance in the higher arch, that is, in the ellipfe; and the height over the point N is to a, the given E K; height over E, as E K* to NM}, therefore equal to ax—— hat and EK; i x the height over # equal to ax ; and the difference equal to mM3—N M3 mM—NM ich i han ax E K x mee which is greater t E aE iar ax E K*x , that NM? xmM3 NM i is, greater than ax EK Saag which is greater than NM, the difference TR difference of the ordinates, for the altitude can fearcely be conceived. to be fo fmall as the difference of the ordinates; confequently there will be a lefs deviation from a true balance in the elliptic arch than in the Gothic. 24. Ir follows therefore, that an elliptic arch, whofe tranfverfe axis is perpendicular to the horizon, is to be preferred to the Gothic arch for ftrength; both becaufe its ftrength exceeds that of a Gothic arch of equal fpan and altitude, when both are in a ftate of equilibration ; and alfo becaufe a given altitude of build- ing raifed upon it and terminated by an horizontal line produces a lefs aberration from a perfect balance of the parts. It follows alfo that the Gothic arch, when carried up to a fufficient height, is to be preferred to a femicircular arch for the fame reafons. Ir feems unneceffary to compare the ftrength of the piers requifite to fuftain elliptic and Gothic arches with the ftrength of the piers of femicircular arches, as, from the great elevation of their vertexes, they are entirely unfit to be applied in bridges, where alone piers are introduced. : vba tango ota i : z satin sh ~ ieatone paras of ‘ae Bits auth ; ty . ‘ ae Bee. 3 eel eit Ae | ‘ ; af.

Lyine-1n HOSPITALS are inftitutions of fuch recent date, and fo few in number, that hitherto we may confider them as in a ftate of infancy. Excepting fome portion of the Hotel Dieu of Paris, which has been long allotted to the relief of poor pregnant women, I know of none that have exifted above forty years, and very few can lay claim even to this antiquity. It can hardly appear unreafonable, therefore, to fuppofe. that imperfeCtions full exift in their management, which time and accurate comparifon may ferve to detect; and although fuch eftablifhments be at pre- fent confined to a few of the capital cities in Europe, it is pro- N bable Read June 6, 1789. [ 90 ] bable their number will increafe as their good effects in fociety are experienced. It is hoped, therefore, that a few faéts and obfer- vations, tending to point out a confiderable fource of error in aa extenfive lying-in hofpital, may be deemed worthy of public notice; both prefent and future inftitutions of this nature may, perhaps, derive fome ufeful information from fuch enquiry. SEVERAL years ago, in attempting to afcertain the nature of the difeafe which is the fubject of the following remarks, I, found the doctrines contained in moft medical books of very little ufe: all the morbid caufes, commonly fuppofed to produce difeafes’ in “infancy, appeared to me inadequate to an explanation of its phoe- nomena. Doubts of courfe arofe in my mind, fome of which have been already ftated to the public*. At length I was tempted to. hazard a conjecture, which then appeared probable, and which fuc- ceeding events /eem to have confirmed: A fketch of the evidence is here, with deference, fubmitted to the candid confideration of phyficians, and of this Academy. Ar the conclufion of the year 1782, of feventeen thoufand fix hundred and fifty infants born alive in the Lying-in Hofpital of this city, two thoufand nine hundred and forty-four had died within the firft fortnight}, that is nearly every fixth child, or about feventeen in the hundred. This was obvioufly a large pro- portion * See Obfervations on the Properties commonly attributed by medical writers to human Milk, &c. Vol. II. of the Tranfactions of this Academy. + See abftract of regiftry at the end of this effay. [ 9: ] portion of deaths, as we fhall prove more particularly hereafter. The difeafe which carried off moft of thefe children, perhaps nine- teen of twenty, was general convulfions, or what our nurfe-tenders have been long in the habit of calling the nine-day fits, as con- ftantly occurring within the firft mine days after birth. As this difeafe has hitherto yielded to no remedy, I have been always more engaged in attending to its prevention than cure. I am chiefly indebted for its hiftory, therefore, to the united reports of feveral of out moft experienced nurfe-tenders. I took down their remarks feparately, and from the whole colleGed what follows. In general it has been obferved that fuch children as are difpofed to whine and cry much from their birth, and fuch as are fubje& to heavy deep fleeps, or ftartings in their fleep, are peculiarly apt to fall into convulfive affeGtions. Twifting of the upper extremities, while awake, without any evident caufe; a livid circle about the lips, and fudden changes of colour in the countenance, have now and then been thought to portend the mwe-day_ fits. Screwing and gathering of the mouth into a purfe, accompanied at intervals with a particular kind of {creeching, well known to the expe- rienced nurfe-tenders, are reckoned fure, and by no means diftant, forerunners. Sometimes previous to thefe fymptoms, and fome- timesalong with them, the infants aré obferved to be unufually greedy for fucking at.the breaft; or feeding by the fpoon ; laxatives given, in fuch fituations, feldom fail to operate freely, fometimes bringing away greenish, flimy, or knotty ftools ; though not unfre- quently they are of a natural yellow oldu as I rte have more than. once feen. N 2 GENERALLY [ 92 ] GENERALLY with one or more of thefe fymptoms preceding, but /ometimes without any warning whatever, the infants are feized with violent irregular contractions and relaxations of their muf- cular frame, but particularly of thofe of the extremities and face. Thefe convulfive motions recur at uncertain intervals, and pro- duce various efie@s. In fome the agitation is very great; the mouth foams; the thumbs are rivetted into the palms of the hands; the jaws are locked from the commencement, fo as to prevent the actions of fucking and fwallowing ; and any attempts to wet the mouth or fauces, or to adminifter medicines, feem to aggravate the fpafms very much; the face becomes turgid, and of a livid hue, as do moft other parts of the body. From this cir-. cumftance, and from the fhorter duration of the difeafe, when it occurs in this form, the nurfes reckon this a different fpecies, and call it the d/ack fits. The confli@ in fuch cafes lafts from about eight to thirty hours, and in fome very rare cafes to about forty hours, when the powers of nature fink exhaufted and over- powered, as it were, with their own exertions. Iv much more frequently happens, however, that the fpafmodic contractions are not fo ftrong as above defcribed; that the extre- mities are rather twifted than convulfed ; that the power of fuck- ing, but more certainly of deglutition, is not loft ’till near death ; that the mouth foams lefs; and that the paroxyfms, recurring at more diftant intervals, continue to harafs the patient from three to five days, and in fome rare inftances to feven and even nine. During all this period the face remains pale ; and the body, from being perhaps very plump, is reduced to a moft miferable fpectre by ; oy by emaciation and difeafe. This the nurfes confider as a fecond fpecies, and call it the white fits. Boru thefe fuppofed fpecies, which may, perhaps, be more: juftly confidered as varieties of the fame difeafe, agree in con-_ ftanily attacking within mzne days from birth, and moft frequently about the falling off of the umbilical chord. This is an event which generally takes place from the fourth to the fixth or feventh. day. Diarrhoea is a conftant concomitant of both fpecies. Long and fad experience have found them alfo to be both equally fatal, infomuch, that the memory of the oldeft perfon does not furnifh: an inftance of one being cured. In order to place my ideas of the caufe of this fatal difeafe in the cleareft point of view, I find it neceffary to have recourfe to extracts from a letter written by me in the year 1783 to the late DoCtor Hutchefon, who was then confulting phyfician to the- hofpital in queftion, In this letter, which was written after having feen fome of the beft regulated Lying-in Hofpitals in London, I ftated to Doétor Hutchefon, Tuat in an old hofpital, which preceded the prefent, but inftituted by and under the care of the fame gentleman, and in a lefs airy part of Dublin, of three thoufand feven hundred and forty-fix children therein born, only two hundred and forty- be [-9¢ j forty-one died within the firft month*, which: are in the pro- portion of one to fifteen and a half, or from fix to feven in the hundred. Tuart during a period of five or fix years in the Britith Lying-in Hofpital, London, of three thoufand fix. hundred and eleven therein born, only one hundred and forty-fix died within the firft three weeks or month, which are as one to twenty-five, or four in the hundred. Taar in the London Lying-in Hofpital I was pofitively affured the death of an infant was a rare occurrence. It is there com- puted with fome confidence (for I was told that no written account is kept) that the number of ftill-born infants far exceeds the number of thofe dying after birth. The proportion of ftill-born we know to be about a twentieth part, or five in the hundred. Tuat near forty years ago, when the difeafes of children were lefs underftood, and more efpecially the falutary praCtice of inocu- lation, DoGor Short computed from fome very extenfive regifters, that London loft thirty-nine per cent. under the age of two years —Edinburgh and Northampton thirty-four or thirty-five—Sheffield twenty-ceight—country places from twenty to twenty-eight ;— whereas in the Dublin hofpital there was loft a number equal to half of that loft in many of thefe places, and nearly equal to the * See the cafe of Mr. Moffe, offered to the confideration of the Irifh Houfe of Commons in the year 1755. [5 9 the whole of that in fome of-them, in #wo weeks, or in about the fiftieth part of the fame fpace of time. From which, and fome other confiderations of lefs weight, I thought the uncom- mon mortality of children in the Dublin Lying-in Hofpital fatis- fa€torily proved. I rHen ventured to hazard fome conjectures concerning the caufes of a mortality, by which fo many ufeful lives were loft to the ftate. rft, Foul air, or an impure atmofphere, ad, Negleét of keeping the children clean and dry, “3d, rregularity in the manner of living of their mothers, mote efpecially in the abufe of “Jprrituous liquors,—were the caufes which appeared to me the moft probable, either feparately or perhaps combined ; but I fufpeéted the firft, viz. an impure or phlogifti- cated atmofphere, for contributing moft powerfully to the general calamity. For, ; First. I remarked to him’ that public regifters proved the mortality of children to increafe proportionably with the fize of towns; and that the larger towns are, the more numerous are the caufes which have a tendency to taint their atmofphere, and thereby render it lefs fit for the purpofes of falutary refpiration. Seconpty, That in private pradtice phyficians in the city of Dublin did hot find the mortality of infants in any degree fo con- ) fiderable L oe J ‘fiderable as our regiftry proved it to be in the Hofpital, a proof that there was here fome peculiar exciting caufe of difeafe. ‘Tuirpiy. That the difference between the mortality of the children in the old hofpital and in the prefent one, when under the management of the fame eminent character, Mr. Moffe, af- forded the ftrongeft evidence in favour of this conjecture. Such differenee could not be fuppofed to arife from any different method of feeding or clothing them, or in the exhibition of medicines ; to me it feemed to originate from a difference in the apartments and accommodations of the women. In the former, which was an old houfe, and never defigned for an hofpital, were one or two, or at moft three beds in the fame room, to each of which there muft have been a door, and one or two, perhaps three windows; whereas in the latter were eight beds in the fame room, and only one door properly fpeaking *, with three windows in fome, and two in others; whence it is evident that the fupply of frefh air in each being nearly on an equality, it muft be much fooner corrupted by the refpiration, lochial difcharges, and other effluvia of eight women and as many children, than by thofe of zZwo or three. Fourtuiy. I obferved, in farther confirmation of this doc- trine, that the Brownlow-ftreet Hofpital in London, which is very favourable * There is indeed a fecond door to each of our large wards, but as it opens into a fmall ward, containing two beds, it is probable the air derived from fuch commu- nication is not very falubrious. The dimenfions of our large wards, in the front of the hofpital, are 36 feet by 23, and 13 in height; in the rere 334 by'23, and of equal height. The finall wards in front are 19 by 12}; and in rere, 18 by 133. E974] favourable to the lives of infants, was an old building, which feemed not to have been originally defigned for an hofpital; in it there were but fix beds in a room with one door, one {mall and three large windows, with a ventilator to each of the latter , that their beds had curtains, but no canopies as in Dublin, and that the utmoft cleanlinefs was in every refpe& obferved. That in the City of London Hofpital, which is an elegant modern building, there are but feven beds toa ward, with two large and four {mall windows to each, one door with a large ventilator over it, the ceilings lofty and perforated by an air-pipe of feveral inches diameter, which paffes out at fome part of the roof. Here alfo the moft fcrupulous cleanlinefs is obferved, and large fupplies of clean linen given both for beds, women and infants ; and here the death of an infant is a rare occurrence, Lastiy. I alledged it was by no means inconfiftent with analogy or reafon to fuppofe that the accumulated effluvia arifing from the bodies of puerperal women and children in lying-in hofpitals might acquire qualities peculiarly noxious to the deli- ‘cate frame of infants. That in other hofpitals and gaols, as the pernicious effects of accumulated human effluvia have been often experienced by robuft adults, it is poffible that degrees of con- tagion inferior to thefe may prove fatal to infants. I concluded with quoting the authority of Arbuthnot, who has obferved “ that “ the air of cities is very unfriendly to infants and children; for “ that as every animal is adapted by nature to the ufe of frefh and “ free air, the tolerance of air replete with fulphureous fteams of “ fuel and the perfpirable matter of animals (as that of cities) is O “ the [ 98 J “ the effet of abit which young creatures have not yet ac- “ quired*;” and that if the air of cities be unfriendly, a fortiorz, fo muft the air of hofpitals in cities, and that in proportion to their want of ventilation. To thefe reafons I might have added, on the authority of Doctor Prieftly, that healthy animals a/mof? a/ways die of convul= fions on being put into air in which other animals have died, after breathing it as long as they could; and that moft other kinds of air, noxious to animal life, produce fimilar effets. See Experiments and Obfervations on different Kinds of Air, vol. i. page 71. Viewinc the fubjedt in this light, I propofed a number of alter- ations intended for the more complete ventilation of the hofpital, and for which I was principally indebted to Mr. White’s excellent work on the management of lying-in women. My obfervations had the effect I wifhed with Doétor Hutchefon and the medical governors. Apertures of a confiderable fize were made in the ecilings of each ward, which have been fince changed for air-pipes of fix inches diameter. Three holes,-of an inch diameter, were bored, in an oblique direction, through each window-frame at top. The upper part of the doors, opening into the gallery, were alfo perforated with a great number of holes. By thefe means a free and eafy paffage was given to the air through the wards at all times, and executed in fuch a manner as to put it out of the power * Effay concerning the Effects of Air on- human Bodies. [ 99 ] power of nurfe-tenders or patients to controul. Since the above period alfo the number of beds in the large wards have been re- duced to feven, and feveral changes made in their conftrudtion, which render them more airy, and more eafily kept clean. The . confequences have been favourable far beyond the expectation of every perfon concerned. The nine-day fits are become vifibly lefs frequent; and the abftract of our regiftry fhews the fact at firft view to the moft imattentive obferver. Of eight thoufand and thirty-three children born /swce the above ferzod, only four hundred and nineteen have died in the hofpital; that is nearly one in nine- feen and-a third, or from five to fix in the hundred. Had the mortality of infants been in this proportion fince the commence- ment of the Dublin hofpital, the number of children dead would have been fomewhat about thirteen hundred, inftead of the prefent number, three thoufand three hundred and fixty-three; or in other words, above two thoufand lives would have been faved to the community. Tuar this diminution of mortality is to be attributed to im+ provements in ventilation can admit, I think, of little doubt. No other new mode of management has been of late pratifed to account for it. No other remedies ufed than fuch as have been tried a thoufand times unfuccefsfully. I know it has been ob- jeGted, that it may be owing to their mothers now remaining a fhorter fpace of time im the hofpital than formerly. In order to afcertain whether this be a matter of fact, I have, for the laft two years, had an entry made of the day on which each infant died; the number dead has been one hundred and fourteen, and they have died on the following days after their birth: O 2 tath [soo] rath day, 11th, roth, gth, 8th, 7th, 6th, sth, 4th, 3d, 2d, ft.

Br ee ek ay. 1. aU. ge) Las aeprnamineds Hence it is obvious that the fatal days are the fifth, the feventh, but efpecially the fixth, and either of thefe are undoubt- edly much within the average day of the difcharge of our patients. Befides, the early difcharge of patients did not commence in any one year, as the leffened mortality of infants did; it arofe from a gradual increafe in the number of poor demanding admiffion ; and I am happy to add, that fome late very liberal donations, and a confequent increafe in the number of our beds, have put an end to the neceffity of this difagreeable expedient, adopted folely with a view of affording indifcriminate relief. Ir might naturally be fuppofed that an atmofphere, which we have endeavoured to prove injurious to the health of infants, would alfo fomewhat affect the chances of life in their mothers. The fat, however, certainly is, that on an average fewer women have died in child-bed in the Dublin hofpital than in moft other lying-in hofpitals, (Compare the abftra@ at the end of this effay with facts contained in the poftfcript to Mr. White’s treatife on the management of pregnant and puerperal women.) Here then a queftion arifes, why fhould infants be fo much more liable to injury from an impure atmofphere than adults? Is it poffible that mothers fhall efcape with impunity and their children perifh ? This, I own, puzzled me extremely, and had almoft made me doubt of what I confidered a fact, fupported by the ftrongeft probable evidence. By accident, however, in looking over a dif- fertation on the food and difcharges of the human body, by our f som J our celebrated countryman, the late Doétor Bryan Robinfon, T found fome facts and obfervations which appear to me to go a great way towards an explanation. In order to make thefe facts intelligible to perfons not very converfant in fuch fpeculations, I muft premife, that Dodor Prieftly has fully proved one great and indifpenfable ufe of refpi- ration to be to carry off or leffen a certain quality in the blood, which is known by the name of phlogifton. That this can only be done by pure air. That by the addition of phlogifton to blood it acquires a deep black colour ; and by its avolation, that blood returns to its natural ford hue. Now Doétor Robinfon found by experiment *, that the weight of the heart, in refpe@t to the weight of the body, is greater in’ children than in grown bodies, and that their quantity of blood is proportional to the weight of the heart. He found alfo, that the quantity of blood, which flows through the lungs in a given time, in proportion to the mafs of circulating fluids, is greater in children than in grown bodies; and that this proportion leffens continually from the birth till bodies arrive at their growth. Hence he re- marks, that as the blood of children paffes oftener through the lungs, it is more fluid and of a brighter colour than the blood of grown perfons. Ir this be a true picture of the conftitution of infants, we muft prefume that fuch peculiarities are intended to anfwer fome very * See page 13, et feq. [ 102 ] very important purpofes in the ceconomy of young animals; and. that in proportion as the intention of Nafure is in thefe refpedts fruftrated, the effets will be more or lefs feverely felt. Would it be deemed a conjecture, exceeding the bounds-of probability, to fufpe&t that the avolation of a very large quantity of phlogifion, and its due feparation from the mafs of blood by pure air, may be effentially neceffary to the growth of young animals; and that this may be one reafon why the impure air of cities has, in all ages, been particularly deftrutive to their health? ‘Wir a view of reducing the une day fits to its proper genus and fpecies in nofology, I have turned over the works of fome ’ of our beft writers on this fubje@. The only genus to which I think it can with any propriety be reduced, is that of eclampfia or convulfion des enfans of Sauvages. But although under this generic title he defcribes feventeen fpecies, there is not one of them to which it bears an exact refemblance. The eclampfia neophytorum of Vander Monde is widely different, as any one may eafily fee by cafting an eye over the hiftory of both. As moft of the fpecies enumerated by Sauvages are fymptomatic, and as he has diftinguifhed feveral of them from various kinds of deleterious fubftances taken into the fyftem; as eclampfia ab atropa, cicuta, &c. perhaps we might with equal propriety add eclampfia ab atmofphezera phlogifticata. TueEre is a fporadic difeafe in Minorca and fome other countries fo very like the nine day fits, in /ome particulars, that it may be worth while here to colle@, under one point of view, a few ex- ~tra&ts concerning it. Nofologifts have given it the title of trifmus L 293°] trifmus nafcentium, “ In hac urbe affliGantur plurimi infantes, adeo feroci convulfione mandibulz. inferioris, ut ea apprehenfi, nullo poffint motu illam movere, et. abhine fuctus la@tis impe- ditur omnino. Tot interficit mala ifta convulfio, ac variole ‘ . ‘4 o “ o ‘ . aut morbilli. In hoc periculum incurrunt recenter nati ufque « is ad nonum fuze nativitatis diem, eoque tranfato, omne difcrimen ceffare docuit Jemper experientia.” For thefe and fome. other obfervations, from the writings of a Spanifh phyfician, we are ‘ . indebted to my fricnd Door Cleghorne’s valuable treatife on the difeafes of Minorca. After the hiftory of the difeafe, the doftor obferves that it is needlefs to add the remedies prefcribed by the Spanifh author, as he ingenuoufly confeffes the difeafe to be fo feldom curable, that in twenty years pra@ife he had {carce known fix to recover. In Germany, Heifter, de maxille fpafmo, obferves “ Quod fi “ fponte, five e caufa interna, hic maxille {pafmus in infantibus, “ ut feepe vidi, contingit ut plurimum moriuntur et vix ullum fer- “ vatum vidi; licet laudatiffima remedia nervina et antifpafmo- * dica interné atque externé quam folertiffimé adhibita fuerint.” Horer, in the firft volume of the Ata Helvetica, has given a long account of a difeafe not infrequent in fome parts of Switzer- land, which Sauvages and Cullen feem to think of the fame fpe- cies with the preceding, but which differs from them very mate- rially in’ fome refpedts. The title of his paper is, De tetano maxillze inferioris in Infantibus. “ Subje@um ifti obnoxium,” fays he, “ eft infans, qui inter tertiam et duodecimam etatis diem “ getatis diem verfatur. Cura hujus morbi, quamvis valde lenta | te Uda, [ 104 ] ‘ fit, attamen fi infans quintam a morbi invafione diem tranfe- “ gerit certiffime felix eft, ideoque dummodo tempus terere poffu- “ mus, res in /a/vo pofita eft.” After giving an account of his method of cure, which confifts of a farrago of diftilled waters, fyrups and inert powders, as may be feen in Sauvages, he con- cludes, “ hac eft methodus applicandorum medicamentorum, qua “ ex tribus egrotulis cures mez commiffis plerumque waus gratia * divina evafit.” A vate French author, Monf. Fourcroy, in a treatife entitled Les Enfans elevées dans lordre de la Nature, remarks “ Quand “ je fuis arrivé en 1744 a St. Domingue, on ne pouvoit elever des “ negrillons dans la plaine du Cap Francois. Ils mouroient “ prefque tous, c’eft a dire eviron quatre vingt fur cent, d'une “ maladie appellée dans le pays ma/ de machoire ou tetanos, qui “ les emportoit dans les mewf premiers jours de leur naiffance.” This diforder he informs us, when come on, is beyond the power of medicine, but that much may be done in the way of pre- vention. From thefe obfervations it is evident, Tuar in certain parts of the world children are more fubject to fpafmodic difeafes than others, Tuat thefe are more apt to come on within z7ne days after birth, THAT ir Boy 3 Tuat coming on within this period they are generally produc- tive of the moft fatal effe@s. And laftly, Tuart their caufes and cure are every where involved in ob- {curity. In each of thefe particulars, there is a ftriking analogy between the trifmus nafcentium or tetanus maxillz inferioris and the mzne- day fits. Ir is farther worthy of obfervation, that the diforders of adults, which are confined to particular: diftri@s or tra@s of country, more frequently arife. from fomething noxious infecting the atmofphere.of fuch places than from any other caufe; and how- ever difficult it may be to apply this doctrine to the cafes in queftion, it at leaft affords fome probable evidence towards the fuppofition, that they originate from fomewhat fimilar caufes. -Sucu are the obfervations which refletion and fome reading fuggefted to me on this fubje@, previous to the publication of the London Medical Tranfaétions in the year 1785. In this very excellent work, however, I met with “ An account of a fingular “ difeafe which prevailed among fome poor children maintained “ by the parith of St. James in Weftminfter;” which appears to me to throw much light on this obfcure.fubject: I hope to be excufed, therefore, for making fome extracts from this, valuable effay, for which the world is indebted to the accurate and learned Sir George Baker. P Sir [ 106 ] Str George'informs.us, that on the 24th day of September, 1782, feventy-three children, viz. forty-fix girls and twenty-feven boys of different ages, from that of feven to fourteen years, were removed from Wimbleton to a large houfe near Golden-fquare. To this houfe thefe children came in good health, and continued fo' for a fortnight; when on the 8th of OGober, a girl aged thirteen years was fuddenly feized with an excruciating pain in the region of the ftomach and in the back, which was foon followed by violent head-ach, de/irium and convulfions. After a few days, another and another girl were attacked exaétly in the fame manner; and towards the end of the month this difeafe had fo prevailed as very much to alarm all thofe to whom the care of thefe children had been committed. On the 29th day of OGober Sir George’s advice was defired. He found mze of thefe poor girls and a female fervant in the fame room fuffering the various effects of a moft dreadful malady. Five were in the agonies of extreme pain, three were moft cruelly convud/ed, and the other two were raving in a fit of delirium. None of them had’ any degree of fever, aud their complaints were always moft fevere immediately after fleep. Thé other inhabitants of this houfe ‘had in general been healthy during the month of Otober, and it is remarkable that the difeafe above defcribed affeGed females only, and was confined to thofe who had flept together in a certain room on the fecond floor. The height of this room was a little more than cight feet, the length twenty, and the breadth fixteen: it contained ten beds, in which it was intended that eighteen girls, two in each bed, and a female fervant fingly fhould fleep ; but Sir George difcovered that this being a favourite room on account of its warmth, was generally crouded at night by ae a [ so7 ] by a much greater number than. its complement: that as much {pace as poflible might be made for beds, the chimney had been ftopped up with bricks, and it had been the conftant cuftom of the fervant at night to keep the door fhut and to.clofe the window fhutters, that as little freth air as poflible might. be admitted. On enquiry it appeared that three candles and a lamp of oil had. -been generally ufed during the night in this chamber, but they were hardly of any fervice, giving a glimmering light. and fre— quently almoft extinguifhed. Sir George advifed. the chamber of the fick to be evacuated. without delay, the healthy to be feparated from. the difeafed, the chimney. to be opened, and whatever tended to exclude freth air to be removed. Thefe direGtions were complied. with, and the patients having been removed to a large apartment (where proper care was taken that frefh air might be admitted) paffed a quiet night free from every fymptom of the difeafe. However, the next morning, immediately on their awaking, they were all feized in the ufual manner, but it was very foon obfervable, that the: paroxyfms returned lefs often and with lefs violence, and fome- times without convulfions, and that during the. intervals the de- lirtum appeared gradually to abate. ' From: thefe and various other important, fats which we cannot here recite, Sir George. conjeures that: the: fource of. this extraor- dinary difeafe was vrtiated air. To me his evidence appears fufi- cient to afford convi€tion to every reafonable mind, and if Iam not _ miftaken, it adds greatly to the probability of the opinion, which » . fuppofes that the nine day fits originated from a fimilar fource. “2 Upon [ 108 ] Upon the whole, from the, evidence adduced, I hope’ the fol- lowing inferences may not appeat improbable. I. THat one effet of an impure atmofphere, on sick i copie body, is to produce fpafms and convulfions. 2. Tuart all young creatures, and etpedially infants within nine days after birth, fuffer moft feverely by fuch a noxious caufe; and therefore 3. Tuat in the con/ffruction of lying-in hofpitals, and perhaps of all public buildings intended for the reception of children, lofty ceilings, large windows and moderate fized rooms fhould be efpecially attended to. 4. TuHat in the arrangement of fuch edifices, no apartment fhould be completely filled with beds, if it can be conveniently avoided ; and s. Tuat in their management attention is efpecially neceffary to cleanlinefs, as well as to the con/ffant and uniform admiffion of atmofpheric air by zzght as well as by day; and Lastiy. That by purfuing fuch meafures with care, difeafes may be prevented which it has hitherto been found dzfficu/t, and fometimes smpoffible, to cure. [ 209.

Water is feldom convenient, wind is a feeble precarious agent, and mufcular force is very expenfive, and very limited; but fteam is free from each of thefe imperfeétions, and is fupe- ior to all in ftrength and duration. Ir has been already applied to work the reciprocating or lever engine, which is furprizingly effe@ual in pumping water, in beating iron, and in other operations which require diftin@ and fucceffive impulfes. _ Bur to make fteam anfwer the various putpofes of mechanics, v3 is neceffary that it fhould be capable of producing a continu- ; R ous 72 1789 [ ¢z14 J eus and rotative motion, which itfelf is more extenfively ufeful than any other, and from which every modification of motion can be eafily obtained. Tuts machine confifts of three principal parts, the wheel, reprefented fig. 1; the cafe, fig. 2, and the , condenfer, which is the fame with that ufed in Mr. Watts’s engine, and requires no defcription. The wheel, fig. 1, has a broad flat edge, a 0, which is truly circular and fmooth; at equal diftances on this edge are placed eight folding clacks or valves, bc de fght; thefe are attached to the wheel by~ fmall moveable joints, which are fo contrived that when fhut they range exactly with the furface of the edge of the wheel, and are capable of open- ing half way, but no: more: For inftance, the valve a 2 m 4, has a joint at 7 m, which. will permit it to open through. the arch 6 & J, until it arrives at the fituation / m, but no) far- ther. Thefe joints are fo pliant that in the revolution of the wheel the valves will fal! open when they defcend near the level of the axis: and when they. afcend above it they will fhut, by their own gravity. Tue cafe of this wheel is. reprefented, fig. 2. The fides of at are at fuch a diftance from each other as that the wheel will exadily fill up the aperture 2 4, and the caps ¢ and @ are fo fitted that the edge of the wheel will come in’ clofe conta& with them. ‘This cafe is fo much deeper than the wheel,’ that the wheel, when fixed in it, leaves a femicitcular vacancy, e f g h, below it, which is exaélly filled up by the valves . of the wheel when extended. 7 is the tube to admit the fieam, a Pers idl fteam, and & is the pipe which leads to the condenfer and drains the machine, both which muft be open, but in all other parts the cafe is fteam tight. a, fig. 3, is a rod which {huts the valves as they approach it; and delivers them clofed into the fteam vefiel. , Wuen the wheel is put into this cafe, and fufpended on its axis, fig. 3, the valves within the cafe will open and fill up the femicircular vacancy: When the fteam paffes up from the ‘boiler through the tube it cannot efcape unlefs through this fe- micircular vacancy, and as this is filled up by the extended valves it muft force them forward in its pafflage to the con- denfer, and confequently turn the wheel round. The condenfer is worked by a crank in the axis, and a rod 6 ¢ extending from it; this caufes a conftant vacuum in that part of the femicircular vacancy which lies between the cap d@ and the valve e f, on which the fteam preffes; by thefe means a power is added to the elafticity of the fteami equal to the preffure of the atmofphere, fo that when the force of the fteam is only equal to the preffure of the atmofphere, and the valves are fix inches fquare, the wheel will be forced round by a power equal to 53141b. fufpended at its circumference. Arter each valve has performed this operation, another fuc- - ceeds it in the like circumftances, and thus the wheel is turned round uninterruptedly by a cheap and fimple contrivance. A workiNe model of this engine, without the condenfer, was exhibited to feyeral members-of the Royal Irifh Academy.

Tur method of working every cafe which occurs in navi- gation is to make the inftrument fimilar to that ideal triangle which is compofed of the difference of latitude, departure and diftance failed ; or to that compofed of the meridional difference of latitude, difference of longitude, and enlarged diftance ; or to that compofed of the difference of longitude, departure, and fine of the middle latitude, which is done by means of the data procured from the compafs, log-line and quadrant; whence it follows, from the nature of fimilar triangles, or from the rela- tion which exifts between the fides, triangles, and the fines of their oppofite angles, that the parts of the inftrument become proportional to thefe which they reprefent, and will afcertain the length of thé lines, or the extent of the angles fought, by its graduations. a To make this general rule more eafily underftood, it is here particularly applied to each of the cafes of navigation. : CASE f sq ] c’A'S EU T Tur Jatitudes and longitudes of two places given, to find the direé&t courfe and diftance between them, Reourrep the courfe and diftance between Lat. 50° 50 N.

Tue advantages expected to arife from the ufe of this inftru- ment are, firft, that no confiderable miftake can exift in the work, as the errors become obvious in proportion to their magnitude ; whereas in calculations, mifplacing a fingle figure will produce an error of the greateft confequence. Secondly, this method does not reft on tables or logarithms, which abound in errors of the prefs even in the beft editions, and are often the fource of much confufion. Thirdly, it will render the art of keeping a fhip’s reckoning eafily learned, and eafily prattifed. Many matters of fhips are perfons who have been raifed to that office from the loweft degree of feamen, who from want of capacity, or want of early opportunities, have acquired only a very fuperficial knowledge of navigation ; many who have been better educated difqualify themfelves by their riotous and diffo- lute lives for the practice of this intricate branch of fcience. The accidents of the fea, and other emergencies, frequently render it neceflary to commit the care of a fhip to an igno- rant failor. In all which cafes the methods of calculating a fhip’s courfe now in ufe can not be adopted or relied on with U fafety, fF. 334) J fafety, and therefore they generally have recourfe to the follow- ing dangerous alternatives : In coafting and in fhort voyages they fail by day, when they may fee the land, fhould they approach it, and Ue fo at night. In longer voyages they get into the latitude of the port failed to by the afliftance of their quadrants, and then fail eaft or weft (which they term running down their longitude) until they flumble as it were on their object. Every day’s experience furnifhes inftances of the melancholy effects of thefe contrivances ; and fhould this fcheme on enquiry be found capable of aflifting thofe who are ignorant of better methods, it is humbly expected that the Academy will give their advice and countenance, as far as may be neceflary, to bring it to maturity, and render it ufeful to fociety. 2 OBSERVATIONS made on the DISAPPEARANCE and REAPPEARANCE of SATURN’s RING in the Year 1789, with fome Remarks on his diurnal Rotation. By the Rev. H. USSHER, D.D. M.R.1 A. and F.R.S. T us year has been remarkably unfavourable in this country Read De. to aftronomical obfervations in general, but more particularly fo _to thofe propofed to be made on the difappearances and reap- pearances of Saturn’s ring. Tue firft difappearance of the ring in the month of May could not from the ftate of the weather be obferved here at all. Aveusr 2ift. I obferved Saturn with the greateft power of the tranfit inftrument; the ring itfelf was invifible, but its fhadow was vifible upon the body, though very faint. U 2 AvGgust cember 5, 1789. [ 136 ]| Avcust 26. Obferved him with the fame power, the ring ftill invifible. Aveust 27. Obferved him with a forty-inch double object- glafs, before he was near the meridian ; ring ftill invifible, at leaft with that power, viz. 61 *, which power I afcertained accurately : rain came on before he paffed the meridian, and the weather continued rainy and cloudy till the goth. Avcust 30. The ring was vifible, particularly on the eaft fide, with the forty-inch achromatic mentioned above: the fame alfo with the greateft power of the tranfit inftf'ument. By com- paring the gradual increafe (as far as I can truft to my recol- le@tion) I imagine that the ring became vifible fome time in the night of the 28th; I mean to one ufing the fame inftru- ments that I did. Ocrozer 1. The ring was juft vifible on the eaftern fide only with the double achromatic, and likewife with the tranfit inftru- ment. Storm came on and continued to the 3d, on which night I got an obfervation, but the ring was not vifible with the tranfit inftrument ; there was a heavy gale of wind. Mr. * Tt is much to be regretted that the generality of obfervers do not mention par- ticularly that they have afcertained the power of their telefcopes by proper experi- ments, particularly in obfervations of this fort. I meafured mine by two different methods, viz. by the breadth of the emergent pencil, and alfo by the ufual method of a diftant circle and near parallel lines, the latter method gave 58, the other 61; this I believe beft. ‘ae ae Mar. Newenham of Cork informed me by letter that he faw it on the eaftern fide to the sth, when at 10H. 30° he loft fight of it. This obfervation he made with a refleiing telefcope of feven feet focus, and power 300. Tue power I ufed was fuperior to this; but the tranfit inftru- ment being fixed, is badly fuited to this kind of obfervation, as the planet paffles the field with great rapidity, and with this inftrument one cannot purfue it; which is a circumftance effen- tially neceffary to diftina vifion, as I formerly mentioned to this Academy in a paper publifhed in the firft volume of our ‘TranfaCiions. Tue obfervations which I have made are hitherto fo badly circumftanced, that any dedué€tion from them with refpe@ to the tables, &c. would be trifling, until the next reappear- ance, which may either invalidate or fortify fuch as have been: mentioned. Ir is, however, worthy of remark at prefent, that Saturn now divefted of his ring appears exceedingly oblate; much more fo than I could have ever fuppofed from common obfervation whilft his ring was vifible: and as his rotation has not, that I know of, been yet determined by any fpots vifible upon his furface, it — occurred to me that if his equatorial and polar diameters were accurately meafured, I could infer his'time of rotation by means of the 19th Propofition of Book III. of Newton’s Principles, by a deduCtion from the formula which he there employed, to find the Be eae the proportion of the polar and equatorial dimeters of Jupiter, by comparifon of the denfity and rotation of the -earth with thofe of Jupiter. Ler T?= the fquare of the time of the fidereal rotation of the earth, and #= the fquare of that of Saturn, the root of which is fought: let A= the earth’s denfity, and ¢ that of Saturn; D= Saturn’s greater diameter, and d his leffer one. Then from Sir dxA Xt Ifuac Newton’s formula I deduce s=V TTF igh 5 a ~ x 23.56" Tue micrometers ordered for the Obfervatory being not yet arrived, I requefted a gentleman of known accuracy to take thefe meafures for me; he was fo obliging as to fend me a great number, agreeing remarkably together, from which I find Saturn’s diameters, reduced to his mean diftance, 18°,12 and 15,855. From hence, taking Sir Ifaac Newton’s ratio of the earth’s equatorial diameter and axis, and that of the earth and Saturn’s denfities, as by him computed, the formula will give for Saturn’s fidereal rotation 10H. 12‘ | Ir is a circumftance worth remarking, that the celebrated Huyghens, in his whimfical and ingenious work, intitled Cofmothe- oros, has the following paffage: “ Qyam habeant dierum longi- “ tudimem (Saturnicole fciz.) certo cognofci nequit; fed ex “ comitis intimi diftantia ac periodo, exque eorum comparatione “cum intimo Jovialium ; verifimile fit non longiores effe dies illas ce Pi egal « jllas quam fint in Jove {ciz. 10 horarum aut paulo minus.” We dwell with pleafure upon the flighteft conjectures of fuch an enlightened mind. By the fame formula I computed the time of his rotation, taking the denfity of Saturn as deduced by Mr. de la Lande in the fourth volume of his Aftronomy, by which it came out 12 H. 55\4- ; I computen it alfo, taking this laft denfity and Mr. Bouguer’s ratio of the earth’s diameters (which has many advocates) and on this fuppofition it came out 14 H. 44° 4 nearly. From the great modern improvement of telefcopes it may reafonably be expected that his time of rotation will foon be determined by actual obfervation; and from the two fatellites lately difcovered by the celebrated Mr. Herfchel, “his denfity will foon be more accurately afcertained. Anp when the denfity of the Georgian planet fhall have been determined by means of his fatellites, difcovered alfo by Mr. Herfchel, perhaps fome corre@t law of the denfities may be had ; which, if it be found to obtain accurately in thofe planets which have fatellites, may, perhaps reafonably, be extended to thofe which have none; and enable us to determine the quan- tity of matter and denfity of Venus, Mars and Mercury, with- out having recourfe to the decrement of the obliquity of the ecliptic, a matter fo delicate in itfelf, that even at this day, there f r40 ] there are fome who doubt the fac, though fupported by found theory and obfervation. Tue following method of determining the quantity of matter in’Mars, Venus and Mercury, or any other planet, is certainly true in theory. . Tue axis major of the earth’s orbit as it revolves round the common center of gravity of earth and fun=200c0ceco. The quantity of matter in the earth we affume=1, that of the fun is then 352813, the parallax being allowed 8.6. Now by Prop.: 60, Book I. of Newton’s Principles, as 47352814: 3,/352513 fo is the axis major of the ellipfe round the common center of gravity, to the axis major of an ellipfe which would in the fame periodical time be defcribed round the fun at reft, and is therefore had by the analogy. Venvs’s axis major (Coff. El. Aft.) round the common center of gravity of the fun and Venus= 144662 by obfervation. Now in the fubfefquiplicate ratio of the periodical times of the earth and Venus take the earth’s diminifhed axis major to a fourth quantity, and we have the axis major of the ellipfe which Venus would defcribe round a fixed fun; but we had it by obfervation round the common center of gravity. Tuen let © = the fun’s quantity of matter, g= that of Venus, let m= the axis major of her orbit round the common center of gravity, and I= that deduced as above round the fixed fun. Then [ t4r ] Then m:1::3/@+9:1@. And m:I3;:@+9:9. Therefore m—I3:13::9:@. And therefore 2: m—I?::©:9. QO, E. I. from whence the denfity is eafily deduced. However I freely allow all the difficulties of reducing this to practice. N. B. If we take the law of the denfities laid down by Mr. de la Lande, viz. as the roots of mean. motion, the denfity of Saturn inftead of ,10448, which is his number, will come out 518351, much nearer to Newton’s, which reduced to this fecale would be ,16750. But Newton’s quantities of matter were neceflarily defective from applying the folar parallax 10',5 inftead of 8°,6. ere Ba. ‘- i } Me ; vi Soieniauk ie: rater oli psc ag ( .

HENRY USSHER, D.D, MRLA and F.R.S. On Thurfday, February 25, at four in the afternoon, as I was on my way from Dublin to the Obfervatory, I remarked that the fun’s light was uncommonly ‘pale; when getting a view of him clear of the houfes, J faw a corona and two pathelia; the parhelia were in the fun’s almacantar, and dif- played the prifmatic colours, the red being next the ‘fun; their tails, parallel to the horizon, were about a degree and an half long; there was no luminous circle parallel to the horizon, as fometimes happens. The corona in which the parhelia were formed was 22° 24° in femidiameter, as meafured by an Hadley’s fextant ; but it appeared to me that it was rather elliptical, the Read March 5» 1790+ longer diameter tending to the pole of the dipping needle, as ~ did manifeftly that of an halo round the moon which fucceeded this phenomenon, and which I have. frequently remarked be- fore. X 2 Bur [ 144 ] But what appears moft fingular, in this phenomenon is, that in Dublin the corona was manifeftly prifmatic, but in the clear air of the Obfervatory it was a vivid white. It continued vifi- ble, though gradually decaying, for thirty-five minutes from the time I firft faw it, and was at length obfcured by ragged clouds from the W. S. W. from which point the wind came, and where there appeared a vaft accumulation of vapour. I could plainly fee that thefe clouds were far below the feat of the parhelia; the whole was fucceeded by a tempeftuous night. The barometer had been rifing, but immediately began to fall to the amount of eight-tenths of an inch in the courfe of the night. As to the elliptic figure of the corona, it is remarked by Opinus that in high latitudes they are more elliptical than in low ones. fi $ ‘ 2 ' * Ay ¢ i" » arre a Fas be " “s % hy PAM Ree of LY} € JZ gaee HP 4 ae ’ ’ liebe aca eer setters is eames OF a aos bona ce adherheen a enetinnermeeet ieee : b ‘ ins f fy . a) Ms *s s a PEA MEO TT AM Miele icin air th ae ey cia ; MAN Todas basse res tet bet thks Gul a Rha ae Be aaa Cen te ee | ‘ fh seeps nennennes Sine crs notte aes « "or 28 | eS Feta Fanaa + Llp, fal] eS Ae aly OO iid tag eeerhitls e003} rr nt pay Eb gar: ve | ‘ a “t fd jot ‘y ie SeBarlidal eos} Shea fouls aT : eewses » | tata (rare tt © } ist a dae eck ae ph : U ; ‘ The Population of Ireland as taken in the Year 1788.

The return made to the Houfe of Commons of this fame year, 1788, was but 614,457, which falls fhort of this return by 7027 houfes. ‘Ihe caufe of this variation is, that we were obliged to take the greater part of the returns from the abftratts, the furvey-books not having come up, In a few inftances the abflraéts contained more than the furvey-books, as the cers included the fe houfes. Whereas the utmoft care has been taken to extract the wafte houfes in this return (except in the few inftances noticed in the column of obferyations) where we were {till obliged to make ufe of the*abftracs. But upon the whole the return from the furvey-books exceeds that from the abftratts by 7027 houfes ; the caufe whereof is, that the officers in their abftraéts fuppreffed feveral houfes which they had returned in their furvey-books (whiclj are fworn to) and kept the money to themfelves. ; The method in which the population has been taken is as follows :—I have felected the moft intelligent bfficers, and have requelted them to fubjoin to each houfe the number of fouls inhabiting the fame; but where they fhould not be able to obtain a clear and fatisfaétory account, to pals by fuch houfe without attempting to give any account whatever of the number of fouls, rather than give one that could not be thoroughly depended upon. Having the books before me, Ifirft find out the number of widows and paupers in the county ; fecondly, the number of new houfes; thirdly, the number of houles with more hearths than one to each ; fourthly, the number of houfes with a fingle hearth to each, which pay duty ; and when I haye fufficient materials T caufe a proportionate number of each fort to be extraéted, till I have the twentieth part of the houfes in the county. ‘Thus in the county of Wexford there are 2111 paupers and widows, fo 1 take the firlt 106 houfes inhabited by perfons of that defeription which appear on the face of the books, with the number of fouls annexed to cach, 106 being as nearly the one-twentieth part of 2111 as 1 can go without a fradion: then I find the number of new houfes to be 766, fo I take the number of fouls annexed to the firft 38 new houfes; then I find the number of houfes having two hearths and upwards to be 2063, fo I take the number of fouls annexed to the firft 163 houfes in that defeription; laftly, I find the number of houfes having but one hearth each and paying duty to be 15,508, fo I take the number of fouls annexed to the firft 775 of fuch houfes, and’ I find the account to fland thus COUNTY OF WEXFORD. ] Number of houfes ‘Terai Number.

In the thirteen counties marked with a 41 have fome grounds whereon I have computed the number of houles omitted ; to wit, the check-furveys made by fopervifors of certain parifhes in each walk, and returned upon oath. Whether the hearth-money collestors have been more or lefs fraudulent in the other parts of their walks than in the parifhes thus furveyed, muft be a matter of accident; but as thefe parifhes were chofen by myfelf, without any previous knowledge that there were more or lefs frauds committed in rhem than in other places, the probability is that the frauds committed in them have been pretty much upon an equality with thofe commitred in other parts of the fame walks collected by the fame officers. If the frauds committed through the thirteen counties be equal to thofe committed in the parifhes fo furveyed therein, then the number of houfes omitted in the faid thirteen counties amounts to about 24,800; and if any of the fuperyifors haye been guilty of collufion or negligence, the number of houfes omitted is probably greater than 24,800. - fo this number muft be added the houles omitted in feyeral of the other counties. The frauds committed in fome of thefe appear as great as in the other thirteen counties. My opinion, formed on a variety of circumftances, is that they amout to 20,000, But I can only give my opinion. i . - ‘The wafte houfes, or thofe returned as fuch, are not included. Many of them, probably fome thoufands of them, were inhabited, The inhabitants frequently fhut their doors, and hide from the colleétor. He frequently returns houfes as wafte which have paid the duty. 2 . ‘In the houfes the population whereof has been taken, no barrack, holpital, fehool-houfe or public building is included. Whether the other houfes in the kingdom contain in proportion an equal number of fouls with the 14,108 houles whereof the population has been taken, mult be a matter of conjecture. If they do, and if the number of houfes amounts to 650,000 (which I believe to be fort of the truth) then the number of fouls in the kingdom muft be computed at above 4,040,000, Som [ 145 ] dn ESSAY paiva afcertaining the. POPULATION of IRELAND. Mma Letter to the Right Honourable the Earl of CHARLEMONT, Prefident of the Royal Irifh Academy. By GERVASE PARKER BUSHE, 44, MR.LA My Lorp, I BEG leave to fubmit to-the Royal Irifh Academy a paper Read June compiled in the year 1789 from the furvey books of 1788. Imperfe& as it is, it may throw fome new lights upon the population and refources of Ireland; and the communication. of it to fo refpeétable a body may lead to the obtaining farther iuformation upon the fubject, under their aufpices. It was my intention to have added the increafed number of houfes returned in 1789; but after having examined fome of. the books, and after a detection of the frauds committed by feveral of the hearth- money colleGors in that year, I find that fhould,I undergo the labour of totting up the number of houfes they have returned, I fhould ftill be left to computation and conjecture. Several increafes. 5) 1790- [ 146 ] increafes indeed over the year 1788 have appeared in the furvey books of 1789. Ihave obferved in the paper that the number of houfes fuppofed to be omitted in the thirteen counties marked with a + amounts to 24,800; I have now reafon to conclude that it amounts to confiderably more. The number fuppofed to be | The increafed number returned omitted in 1788 was, in 1789 1s, In the county Longford - tooo | 2143 In Kerry - - - 1900 | 2441 In Clare - - - 2500 | 2482 In Limerick - - 1600 | 2090 In Cork - - - 8000 47460 in about 4a/f the county. In Tipperary —- - 1000 | 833 in about one fifth part of the county. In Donegal - ~ - 2500 | 2304 in about one fi/th part of the county. Ir would be ufelefs to give an accurate account of returns which I know to be deficient; my utmoft labour could lead me to nothing more than a tolerable computation. I am perfectly convinced that the houfes fuppreffed in 1788 in thefe thirteen counties, which I computed at 24,800, do amount to 40,000; and I have now fome grounds on which I can compute the number omitted in the remaining nineteen counties. I believe that when I eftimated them at 20,000, I did not exaggerate. It may eafily be conceived that there may be fome official reafons which f 147 ] which may make it imprudent to publifh the particulars, or to divulge to the officers the exa&t quantum of my expectations from each of them; but I have no objection to fhewing to any member of the Royal Irifh Academy the principal grounds of my compu- tations, the returns from which the accounts of population have. been taken, the inftru&tions to the officers under which thefe returns have been made, and to let them judge of the im- partiality and care with which the computations have been formed.. ; In the paper which I have enclofed I have obferved that if the number of houfes amounts to 650,000, and if they contain an equal number of fouls to each with thofe whereof the popu-- lation has been returned, then the whole number of imhabitants tuft be computed at above 4,040,000. That we may fafely add 30,000 houfes to the computed number of 650,000, I have no doubt whatever; but as to the number of fouls which fhould be allowed to each houfe, I can by no means fpeak with equal confidence. Since the compilation of the paper I have received. fome farther returns. In [) gs J Counties, No. of | No. of | Perfons from whom T received the Houfes.| Souls. Returns.

The population of Merrion-fquare and Sackville- ftreet, and of the many other parts of Dublin, is fictitious. The fame perfons are counted over again in the country. And whether the fouls contained in the Barracks, College, fchools and public buildings of Dublin (which have not been counted) may make ,up for the number which migrates during the fummer, is a matter [ 49 J a matter which I have not at prefent fufficient materials to determine. Upon the whole, thefe returns of population exceed the returns in the paper; but in my opinion we fhould be nearer the truth by forming our conjectures upon the paper alone, than by adding thefe to them. To: ‘acquire: complete knowledge upon the fubjeCt requires more affiftance than I-can expe& from thofe officers who are concerned inthe colleétion of hearth-money. The office of a tax-gatherer is not popular, and he has not the fame facility of _ acquiring information which the gentlemen of the country or the perfons employed by them would have, if fome’of them fhould think proper to affift in the enquiry, and to return lifts of the number of perfons contained in the houfes of their refpetive neighbourhoods. To the hearth-money colleétor the people fre- quently refufe an an{wer. The wealthy, or their fervants, often think the queflion impertinent, and the poor often fufpea that it is afked with fome bad defign. From careleffnefs, and from fufpicion, fome ‘of the inhabitants are frequently forgotten in the enumeration. I cannot fay that in any place where I have checked the returns by a partial return made by other officers, I have found the numbers to have been exaggerated. In a country where the local population varies fo much in the different parts of the fame county, it feems to me impoffible to arrive at any thing like accuracy, unlefs we fhall be able to obtain returns - from different parts of the fixteen counties where the popula- tion has not yet been taken. Should they fall fhort of the returns I have received, perhaps the population of the kingdom may fill be eftimated at above four millions. The inhabitants of 30,000 ¥ ~ houfes [ x50 ] houfes may certainly be added to the number conjeQured in the paper, and together with the inhabitants of the public build- ings, they would make up for confiderable deficiencies. I coutp have wifhed to have marked the proportionate pro- grefs of building and of population in the different parts of the kingdom, and to have traced the effe€ts of the linen manufaature, and of encouraged or neglected agriculture ; but after much exa- mination I find myfelf more capable of warning others againft falfe conclufions, than of leading them to true ones. The increafes which appear on the face of the paper are’ no evidence whatever of the proportionate increafe of each county; they depend prin- cipally on the accident of having had lefs faithful offtcers in a particular diftri@t in 1777, or on being more fortunate in 1788. The reader who {hall conclude that the county of Monaghan, where the houfes appear to have almoft been doubled in num- ber fince 1777, has made a greater progrefs in population than. the county of Limerick has made in the fame period, will draw kis conclufion from very uncertain premifes.. Accorprne to Sir William Petty, the houfes amounted in 1672 to but 200,000, of which 160,000 had no fixed hearth, 24,000 had but one chimney, and 14,000 had more chimnies than one, and the people were but 1,100,000. If we can believe that under a variety of difadvantages which are now removed, Ireland did in an hundred and fixteen years more than treble her popu- lation, our expectations of future increafe may be great indeed. But I cannot give implicit credit to the returns of the number of Le ae of houfes in the time of Sir William Petty. When I refleé that in 1786, when {worn officers had been appointed to colle& the duty, and after the frauds of feveral of them had been detected and punifhed, there were houfes fuppreffed to the number of near two hundred thoufand, can I fuppofe that the lifts formed in 1672, under lefs effectual laws, and a more imperfe@ method of calculation, could have been free from fraud and error? In many refpects, however, Sir William Petty’s tra@ contains true and valuable information; and I believe that he was a writer to be much relied upon as to any matter which he cow/d know. I can readily believe that the houfes of Ireland, though probably more numerous, were to the full as wretched as Sir William Petty reprefents them. The perfons who then colle&ted hearth-money could have had no temptation to return houfes as having zo fixed hearths which had fixed hearths. An houfe without a fixed hearth was not exempted from duty, but by the 17th and 18th of Charles II. it was to be charged as having wo hearths. It fhould feem that the legiflators of that day were fenfible of the wretchednefs of their fellow-fubjeds, and thought double taxation an admirable receipt for curing poverty. Thefe 160,000 honfes, the common abodes of the Trifh peafantry, are defcribed by Sir William Petty as not worth five fhillings each building: Compare Sir William Petty’s account with the enclofed paper, and we may contemplate with pleafure the progrefs of Irifh profperity.. Sir William Petty’s computation of 5 to each houfe, I fuppofe to have been founded on fome enquiry, though he does not ftate the grounds on which he formed it. Ireland was at that day a country of pafturage, and Ware the eae J the caufes which appear to me to accoynt for a greater number of fouls being generally found in the houfes of Ireland at prefent, did not exift in the time of Sir William Petty. ‘Timber was probably more plenty ; the wretched habitations, worth but five fhillings each, could not hold two families; and another houfe, fuch as the peafant was accuftomed to, was eafily built. Probably he had neither a male nor a female fervant, as is ufual with many of the peafants in the tillage counties; nor an. apprentice, as is cuftomary in the North. Ir the actual population of Ireland fhould be found’ greater in proportion to the number of the houfes than. that of other countries, perhaps the following caufes may. account for the fad. The great body of the people who inhabit 450,756 houfes of one hearth each, paying the duty (as they are returned in the paper), but who probably inhabit 500,000 houfes, appear to me to have generally arrived at that ftate of induftry wherein a man becomes valuable, and the price of his labour is on the increafe; but not at that ftate of profperity which would enable them to procure as comfortable habitations as may be feen in other countries. They are almoft all married, and there are few inftances of their not having children. They generally marry young; and potatoes being their general food, they are under no apprehenfions of being unable to fupport their children ; perhaps too for children there is no foad fo good. Thefe children are their wealth; the father, therefore, is in no hurry to part with his fon till he marrics, and will ftay with him no longer. Even after marriage the fon or the daughter frequently lives with the parents. THE E hes J Tue houfes are built, not by the landlord, but by the tenant, and to build an houfe for his family is not always an eafy matter to an Irifh peafant: The fearcity of timber and of watling is an additional impediment. In the tillage counties (and tillage is becoming very general) if the peafant arrives at better circumftances, it is after a courfe of painful induftry ; and money fo acquired is not readily parted with. He is more defirous of taking more land than of improving his houfe. He lives in the fame fort of habitation that he has been. ufed to; and that his poorer neighbours inhabit, but he hires labourers and fervants who live in his houfe; and increafes the number of his houfchold without increafing their accommodations. How- ever I may contradic the opinions of others as to the nature of the Irifh peafantry, I will venture to ftate what I have obferved in a county where tillage has taken root. I think that no peafantry can be more induftrious ; and the continued frugality of thofe who have grown rich is perfe@ly aftonifhmg. The fhortnefs of tenures is another caufe that the peafantry are unwilling to build houfes in feveral parts of the kingdom, and of courfe of families not feparating early. J am happy to obferve that in my own memory the peafantry have grown more intel- ligent, more fturdy, and have more confidence in the laws then they ufed to have. But I am informed, and I cannot difbelicve, that in thofe parts. where the lands are let to middle-men, the peafant wifhes ftill to conceal his fubftance, and efpecially that he is unwilling to build a good houfe, which would only increafe the rent of his farm, of which he generally has but a. fhort tenure. : Upon [ 254 4 Uron the whole, I believe that more peop'e aré crowded into one houfe in Ireland than in other countrics, for two rea- fons; firft, that many cannot afford to build; and fecondly, becaufe thofe who can, have many motives to prevent them. Notwithftanding this the new buildings in an increafing country cannot be inconfiderable. We fee by one of the columns in the paper that they amount to i8,824 in.one year; and I be- lieve that column to approach nearer to the truth than any other in the paper. In order to know the real annual increafe of houfes, we fhould dedu@ from that number the houfes which have gone to decay; and there is fo much fraud and error in the accounts of them, that I can give nothing more than a loofe conjeure. I believe they may amount to about nine thoufand. Perhaps there may be another caufe for the number of people being fo great in proportion to the number of houfes; in my opinion the being without poor rates has that effect. When the labourer dies, his houfe is often broke up, and his family is divided amongft the neighbouring peafantry. Thofe who are able to work hire with them as fervants; and even thofe who are not fo, are readily taken by their neighbours, both from kindnefs, and from the hope of future affiftance from their labours. Even in the houfes inhabited by widows and paupers I do not find the population to run very low, but it is very unequal. In one houfe I frequently find but one poor widow ; in the next the remains of two, three or four families living together. In the newly inhabited houfes the population runs low; the caufe is that many of them are not /u//y inhabited, which finks their general average; fometimes there is but one fervant in the houfe. In the houfes of two hearths and upwards, inhabited by the gentry, orgs] gentry, and by wealthy farmers and manufadturers, the popu- lation uniformly runs the higheft. I have the honour to be, With the greateft refpedt, My Lord, Your Lordfhip’s moft humble fervant, G.P.

Mais en m’occupant a reconnoitre les pefanteurs fpécifiques de ces fluides, et les proportions des augmentations de denfité produites par Yalliage de l’'alkool avec l'eau, je congus l’efpoir de parvenir ad trouver la loi générale de ces pénétrations ou abforptions d’ une liqueur par l’autre, et je me fis en conféquence le plan d’ un trés grand travail dabord fur les liqueurs fpiritueufes, en- fuite fur les acides et toutes les fubftances falines en général ; fur les métaux et enfin tous les corps qui acquiérent dans leurs alliages mutuels une augmentation de denfité; perfuadé qu'il doit y avoir a cet égard une loi générale dans la nature qui tient a celle de I’ attraétion et dont la découverte pourroit donner de grandes connoiffances fur les affinités chimiques. Mais des circonftances particulieres m’ ayant empeché alors d’ entreprendre ce travail et méme d’achever celui que j’avois commencé fur les Eaux-de-vie, je n’ ai pas pu m’en occuper depuis plus de dix ans, et j'attendois une occafion favorable pour le reprendre. Je me félicite aujourdhui de ne I’ avoir pas fait, puifque vous travaillez fur cet objet intéreffant et que vous avéz déja fait de trés grands pas dans cette carriere. Vous la parcourrez furement avec plus de fuccés que je n’aurois pu le faire, et je fuis perfuadé que fi vous continuez 4 vous en occuper, nous vous devrons la décou-— verte d’ une loi de la nature encore inconnue. Agréez je vous pric I’ hommage des effais que j’ai tentés pour parvenir 4 connoitre un des faits qui peuvent y conduire. Dans [ s50 if Dans I’ éxamen de la pefanteur fpécifique des Eaux-de-vie ou des mélanges d’ alkool et d’cau, jai été dabord arrété par une trés grande difficulté, celle de déterminer les termes fixes et de décider ce qu’on doit prendre pour alkool pur. Je confidere cette liqueur comme une mixte dont l’eau eft un des principes conftituans, enforte qu’on ne peut la lui enlever enti¢rement fans le détruire et en faire une fubftance différente, comme I’ Ether. La volatilité de |’ alkool plus grande que celle de I’ eau, ou fa plus grande affinité avec le feu, donne le moyen de f{éparer une partie de l'eau furabondante. Mais il n’y a pas de procédé, du moins je n’en connois pas, par lequel on foit affuré denlever exaGtement toute cette eau furabondante, en laiffant Peau. principe, de maniere que lalkool foit auffi deflegmé quil eft poffible fans avoir fouffert d’altération et de changement dans fes propriétés. J'ai cru ne devoir pas m’occuper longtems de cette recherche et me fuis contenté d’ examiner les alliages d’eau et dalkool quelconque dont la pefanteur fpécifique feroit dans un rapport déterminé avec celle de l'eau diftillée, et pour cela prenant de l’efprit de vin foible du commerce, trés pur: cefta dire, qui n’étcit point altéré par le mélange des fubftances étrangéres, et auffi débarafié qu il étoit poffible de l’ huile du vin (qui y eft fouvent en affez grande quantité pour étre reconnue . par le gout Empireumatique :) je I ai rectifié par plufienrs diftil- lations fucceffives au bain marie, et il a été réduit 4 peu prés, au rs5™* de la premiere quantité. La pefanteur fpécifique de cet alkool étoit 4 celle de eau comme 0.8199, 21, a la tem- perature de 15 degrés du thermométre de mercure de Reaumur. Z 2 Vous { ae ] Vous avez toujours fait vos alliages d’ eau et d’acide en — mélant enfemble des poids déterminés de ces liqueurs. J'ai fuivi une méthode différente. Et confidérant la pefanteur fpccifique _feulement comme un moyen de reconnoitre laugmentation de denfité, ou la diminution de volume, j’ai cru parvenir plus direfement au but que je me propofois, en déterminant les quantités de liqueur qui devoient former [alliage, non par rapport a leurs poids, mais par rapport a leurs volumes, et j’ai compofé dix mélanges contenant le premier g mefures d’alkool et 1 d'eau; le fecond 8 mefures d’alkool, 2 d’eau; et ainfi de fuite jufques au dernier qui ne contenoit qu’ une mefure d’ alkool et g d’eau. Mais comme les mefures a@tuelles font tou- jours incertaines, j’ai employé la balance pour déterminer les pefanteurs fpécifiques reconnues, ainfi 10,000 grains d’ eau et 8199 dalkool formoient un mélange 4a parties égales en volume. Apres que tous ces mélanges ont été bien faits et parfaite- ment refroidis (car j'ai reconnu, ainfi que vous l’avez fait par rapport aux acides, quil faut un tems affez long pour Jalliage complet, furtout lorfque Peau eft en grande proportion) la pe- fanteur fpécifique de ces liqueurs a été reconnue au moyen de la balance hydroftatique. J’ai employé aufli un autre inftrument qui me paroft encore plus propre 4 donner des réfultats exacts, principalement lorfqu’on ne veut avoir que des rapports, et qu’on ne cherche pas a reconnoitre la pefanteur réclle d'un vo- lume déterminé de la liqueur. C’eft lAréométre de Farenheit. Vous favez quil a une tige trés courte, fur laquelle il n’y a gu’un feul point marqué et furmonté d’un petit godet defliné a recevoir les poids qu’on y place pour faire caler l’aréométre toujours [ ane ] toujours jufques au méme point, enforte qu'il mefure toujours auffi des volumes de liqueur égaux, dont le poids eft celui de Yaréométre plus ceux ajoutés dans le godet. C’eft donc une vraie balance hydroftatique; mais avec laquelle on a l’avantage de pouvoir pefer des volumes de liqueur auffi grands que l’on veut, et par conféquent de diminuer les erreurs fans rifquer de fatiguer le fléau d’ une balance par un poids exceflif, et de la rendre moins fenfible. Il eft vrai qu'il faut prendre quelques pré- cautions dans lufage de cet inftrument, comme de lui donner la méme température qu’ aux fluides qu’on veut pefer, furtout sil eft de metal; d’employer des vafes affez grands pour: qu'il foit fuffifamment ¢loigné des bords, d’ empécher que. dans les ba- lancemens le godet ne touche a la furface de la liqueur, dont PattraGion produit alors un effet fenfible, ce qui pourroit indi- - quer un moyen de mefurer la force de l’attraction des fluides avec différens corps. Mais comme vous étes bien plus verfé que moi dans l’art des experiences, je crois inutile d’ entrer dans beau- coup de détails 4 cet égard. Jobferverai feulement qu'il. eft effentiel de conftruire cet aréométre de maniére qu’on ne foit pas obligé d’ajouter beaucoup de poids dans le godet pour le faire caler, parcequ’alors il ne peut pas conferver fon équilibre, et il arrive quelquefois qu'il fe renverfe. Il faut donc, lorfqu’on veut exa- -- miner des liqueurs dont la pefanteur fpécifique differe beaucoup, trouver les moyens de lefter plus ou moins Tardéométre fans changer fon volume. Celui dont je me fervois, et dont le volume étoit d’environ trois pouces cubes, étoit conftruit en cuivre, et javois fait faire plufieurs poids en forme d’olives qu’on pouvoit viffer au bas de l’inftrument et fubftituer lun ad Vautre. Leurs volumes étoient parfaitement égaux et leurs pefanteurs différentes. Il f ke6a}] Il faudroit pour les acides en conftruire un de verre, dont la tige feroit un tube mince et ouvert, tetminé par un ‘petit entonnoir, par lequel on verferoit le mercure néceflaire pour lefter Pinftru- ment 4 chaque expérience, de maniere qu’on ne fat obligé de placer enfuite dans cet entonnoir fervant de godet que de trés petits poids pour faire plonger cet aréométre jufqu’ a la ligne marquée avec un diamant fur le tube. Jen ai peut-éire trop dit fur cet objet; mais comme. il paroit par votre lettre a Mr. Chaptal que vous defirez de connoitre les. moyens que j’ai employés pour determiner les pefanteurs f{pé- cifiques, j’ai cru devoir décrire les infiruments dont je me fuis fervi. ConnotssanT les pefanteurs fpécifiques réelles, ou comme vous dites phyfiques, des mélanges dalkool et d'eau, prenant une moyenne entre un trés grand nombre d’obfervations toutes faites a la méme température de 15 degrés, et les comparant aux pefanteurs fpccifiques mathématiques calculées. direftement par la fimple regle dalliage, on peut en conclure augmentation de denfité ou la diminution de volume produite dans la maffe totale par la pénétration mutuelle des fluides. Car nommant A la pefanteur fpecifique phyfique, B la pefanteur fpécifique mathé- matique, # le nombre des mefures qui compofent la maffe totale, #—x celui auguel il. eft réduit par Veffet de la “péné- tration, il eft évident, puifque cette augmentation de denfité ne diminue pas le poids de la maffe totale, que ~B=z—xxA.

Les plus grands répondent au mélange de parties égales, et les autres vont en décroiffant depuis ce terme jufqu’ aux deux extrémes de la progreffion.

J'ai taché de la découvrir et de concilier différentes hypothéfes avec cés obfervations ; je me fuis \ enfin arrété a celle que je vais vous expofer. ConsrpERaAnT l'alkool comme diffous par l'eau qui en a abforbé et retient une partie dans fes pores (Sans attacher. d’ail- leurs un fens bien ftri€te a ce mot de diffolution), La quantité abforbée doit étre en raifon de celles du diffolvant et du corps diffous, et chaque mefure d’eau retiendra des quantités d’alkool . proportionelles au nombre de mefures de cette liqueur qui feront entrées dans le mélange. Ainfi, par exemple, dans un alliage formé de 9 mefures d’alkool et une d'eau, cette mefure d’eau ab- forbera une quantité d’alkool qui. fera comme g: et dans un autre mélange de 8 mefures d’alkool avec 2 d’eau, chaque mefure d’eau abforbera une quantité qui fera comme 8; mais qu'il faut multiplier par 2, nombre de mefures d’eau, pour avoir la dimi- nution totale du volume.

Mais il n’en eft pas de méme pour les alliages ot l’eau eft en plus grande proportion. Leurs augmentations de denfité réelles font beaucoup moindres que le calcul ne lindique, et les différences deviennent d’autant plus confidérables que la quan- tité d’eau eft plus grande. Par l’hypothefe et fuivant la formule ea" xn, le plus grand des termes doit étre celui qui ré- pond au mélange de parties égales, et les inférieurs doivent étre égaux aux fupérieurs chacun a chacun. Cependant.cela n’eft point; et les termes inferieurs de la table décroiffent fuivant l'expérience beaucoup plus rapidement que les fupérieurs. Si on divife les termes par les nombres correfpondans, qui expri- ment les quantités d’alkool contenues dans chaque mélange, les quotiens indiqueront combien chaque mefure d’alkool a perdu de fon volume dans l’alliage, et ces nombres, devroient par l’hy- pothefe former une progreffion arithmétique croiffante, puifque le nombre de mefures d’eau augmente dans cette proportion. Elle eft en effet affez réguliere depuis le premier terme jafqu’ A celui de mélange de parties égales. Mais enfuite les différences deviennent fucceflivement plus petites et méme enfin négatives. Il paroit donc que lorfque la quantité d’cau eft plus grande que celle de Valkool, la loi de cet alliage et de l’abforption eft troublée, [ rye J troublée; qu'il y a ici une caufe qui agit en fens contraire de la premiere et s'oppofe a fon effet. On a en Phifique plufieurs exemples de phénoménes femblables, ot deux caufes l'une pofitive autre négative agiffent en méme tems, comme Mr.de Luc I’a dévelopé par rapport a la dilatation et d la condenfation de l’eau. Je penfe que la caufe négative eft dans ce cas-ci l’attraction refpective des parties de eau, qui tend a les faire demeurer raffemblées, et soppofe par conféquent aleur réunion avec une autre fubftance. Elle: eft vaincue par leffet de l’affinité plus forte de Tlalkool, lorfque la maffe de cette derniere liqueur eft plus grande que celle de Yeau, ou au moins égale. Mais quand le volume d’eau devient trés grand par rapport a celui d’alkool, alors cette caufe négative, qui n’eft plus fuffifamment contrebalancée, commence 4 agir et ad diminuer fucceflivement les effets de Vattraction de ces deux liqueurs. Je vous prie de confidérer, Monfieur, que je ne préfente ceci que comme une conje@ture, mais qui me paroit affez vraifemblable et confirmée par quelques expériences. Je n’en citerai qu’une bien connue de tous ceux qui font le commerce des eaux-de vie. C’eft l’extréme difficulté qu’on trouve a méler parfaitement une petite quantité defprit de vin 4 celles qui font trop foibles. Le mélange ne fe fait jamais bien com- plettement 4 moins qu’on n’agite et qu’on ne roule les barriques: et j'ai reconnu quelquefois, méme aprés plufieurs jours, que Yefprit de vin ne s’étoit pas également répandu dans toute la maffe. Mais il ne fuffit pas de connoitre la caufe générale des différences d’augmentation de denfité entre les alliages qui conti- ennent plus ou moins d’alkool que d’eau; il faudroit encore dé- terminer la maniere dont cette caufe agit, et en découvrir la loi. Ceft —————— EE —— fae) C’eft ce dont je me fuis occupé. Je croyois méme l’avoir trouvée, lorfque je fus obligé d’abandonner ce travail, avant que d’avoir pu faire les expériences néceffaires pour décider la queftion. Ainfi cette partie de mes effais eft trop incomplete pour que je puiffe la mettre fous vos yeux. Mais je crois pouvoir pofer en principe que dans tous les mélanges ‘d’alkool et d’eau, ot l’alkool forme au moins la moitié de la mafle totale, les augmentations de denfité, ou ce qui eft la méme chofe, les diminutions de volume font entre elles, comme les produits des nombres qui expriment les proportions d’alkool et d’eau, qui forment le mélange et peu- Acnx—4cx* = vent étre repréfentées par la formule z= Jozserverat que cela me fuffifoit pour remplir l’objet que je me propofois d’abord; parce qu’il n’y a pas dans le commerce d’eau-de-vie moins fpiritueufe que mon mélange a parties égales. Ainfi on peut au moyen de cette formule déterminer les degrés de fpirituofité de toutes les eaux-de-vie et efprits de vin du commerce ; ou en d’autres termes trouver quel eft le nombre de parties d’eau et de mon alkool dont on peut les fuppofer com- pofées et pour cela faifant, Le nombre de mefures de la maife entiere, ou le volume total - = - - == DAG, Celui des mefures d’alkool contenues dans un mé- lange quelconque - - - = [ reg La diminution du volume du mélange a patties égales reconnue par l’expérience - - =e La diminution du volume du mélange contenant. « mefures d’alkool eft par Phypothefe - - = 4c0— 40x" La pefanteur fpécifique de l’eau - - =a celle de Palkool - site ada 7 celle du mélange inconnu ~ - =y On aura, puifque l’augmentation de denfité ne change rien au poids de la maffe, 1—xxXa-+bu= 1—4ex-+ 40x XY.

Mais ce travail n’eft point terminé. S1 vous penfez, Monfieur, que la route que je fuivois peut con- duire au but que je me propofois pour parvenir a la connoiffance des pefanteurs {pécifiques de ces liqueurs, et que vous defiriez @éclaircir ees a d’éclaircir entiérement la queftion, je crois que vous y parvien- drez aifément foit en faifant de nouvelles expériences fur l’alkool, foit en vous occupant des acides. I] me femble méme qu'il fera plus facile de réuflir par ce moyen, les diffirences des pefan- teurs fpécifiques font plus grandes, les mélanges moins fujets a s’ altérer par l’évaporation, et l’affinité avec l’eau bien plus mar- quée. Jai lieu de foupgonner que les augmentations de denfité fuivront la méme loi. J’ai trouvé des rapports affez juftes en réduifant quelques uns des termes des tables contenues dans votre mémoire 4 la méme forme que les miennes; mais pour s’ en affurer parfaitement, il faudroit faire une fuite d’expéri- ences particuliérement deftinées 4 cet objet, déterminer les dofes par le volume, et furtout compofer un aflez grand nombre de mélanges ov l’eau fit en moindre quantite que l’acide, afin de connoitre la loi de la pénétration dams ce cas 1a qui eft le plus fimple, enfuite augmenter fucceflivement la dofe de l’eau pour s aflurer fi cette loi eft troublée, et dans quel rapport. Si vous découvriez que les acides font abforbés par l’eau fuivant le méme rapport que l’alkool, il refteroit 4 comparer les différentes dimi- nutions de volume qu’ éprouvent ces différentes liqueurs, et chercher fi cela a quelque rapport avec leurs degrés d’affinité. Je Vois par exemple que votre huile de vitriol étant mélée avec Yeau a peu prés a parties égales, il y a une diminution de 0.085 de la maffe totale, par conf€quent environ trois fois plus grande que celle de Valkool. Ainfi l’eau en retient dans fes pores trois fois plus, quoique cet acide foit plus denfe que Palkool dans une proportion plus que triple. D’ow on pourroit peut-étre con- clure que laffinité de Teau avec cet acide eft fix fois plus forte que celle avec Valkool, puis qu'elle lui fait abforber fix Bb. 2 fois hie, Se fois plus de maticre. Mais je fens parfaitement qu'il faut avoir recueilli bien plus d’obfervations pour étre en droit de tirer de pareilles conféquences. Je defire feulement que cet objet vous paroifle mériter votre attention, et fi vous fefiez quelques expé- riences a cet egard, je vous prierois de vouloir bien me les faire connoitre. Ix me refte 4 vous parler des dilatations des mélanges d’alkool et d’eau, dont il faut connoitre les effets pour déterminer les pe- fanteurs fpécifiques, 4 toutes les températures. Ce n’eft pas la partie de la queftion qui préfente le moins de difficultés ; et je n’ai pas fait tout ce qu'il faut-pour les réfoudre. Je croyois que Yaugmentation totale du volume produite par la dilatation a une temp‘rature quelconque, ¢toit la fomme des dilatations de Yeau et de Valkool qui compofent le mélange, moins celle de la partie d’alkool abforbée par l'eau. Mais j’ai vu par mes expé- riences et par celles de Mr. de Luc que cela n’eft point exact. — En fuppofant méme cette théorie, il n’eft pas bien facile de déter- miner d’une maniére générale les dilatations de tous ces alliages, puifque celles de eau et de l'alkool, non feulement ne font pas égales, mais encore ne font pas femblables, et les degrés de leurs échelles ne font pas proportionels. Le changement de tempe- fature qui fait parcourir au thermométre d’efprit de vin, la moitié de fon échelle depuis le terme de la glace jufqu’a celui de l’eau bouillante, ne fait parcourir 4 celui d’eau que les 24 de la fienne. Il fuit deld que les mélanges d’alkool et d’eau ne doivent étre ni également ni femblablement dilatables ; et qu'il faudroit déterminer pour chacun d’eux, non feulement fa dilata- tion abfolue (c’eft-da-dire la quantité dont fon volume augmente a une Beni eed a une température donnée), mais encore fon échelle particuliére de dilatation comparée a celles de Valkool et de l'eau. Matcre cette difficulté, ayant reconnu que les dilatations des eaux-de-vie, dont la pefanteur fpécifique ne differe pas de plus d’un centiéme, pouvoient étre confidérées fans erreur fenfible comme femblables et proportionelles, j’ai ofé efpérer de parvenir a conftruire un aréométre avec lequel il feroit poffible de recon- noitre les degrés de fpirituofité de toutes les eaux-de-vie 4 toutes les temperatures et dont Vexactitude feroit fuffifante pour la pratique: Je vais vous expofer auffi bri¢vement que je le pour- rai mes idées 4 cet égard. Comme il faut toujours employer le thermométre en méme tems que le pefe-liqueur, j’ai voulu réunir ces deux inftrumens et méme leurs ¢chelles; en forte que celle du thermométre fervit de graduation 4 l’argéométre.

Faifant enfuite un thermométre avec la méme eau-de-vie colorée, conftruit de fagon que la diftance entre les degrés 15 et 30 foit Cgale a celle qui fe trouve fur la tige de l'aréométre entre les deux points qu’on y a marqués, et y placant ce thermométre enforte que ces déux points cor- refpondent aux degrés 15 et 30, il eft evident que cet aréo- métre s’ enforcera toujours dans l’eau-de-vie, qui a fervi a le conftruire, quelle que foit fa temp-rature, jufqu’ au point qui fera marqué alors par fon thermométre, pourvu que la liqueur qui eft contenue ait le méme degré de chaleur que celle dans laquelle nage linftrument. Il fervira donc 4 faire connoitre fi Yeau-de-vie dans laquelle on le plonge a le méme degré de fpirituofité que celle dont la pefanteur {péicifique eft 0.9275 a la température de 15 degrés. Mais puifque la liqueur du ther- momeétre s’éleve toujours au niveau dans cette eau-de-vie, il en réfulte que dans une autre plus fpiritueufe et par conféquent plus légére, le point marqué par ce thermométre fera conftamment au-deflous de ce niveau et s’ élevera au contraire au-deflus dans celle qui contiendra plus d’eau. Le nombre de degrés compris entre le point d’immerfion et celui de thermométre déterminera les differences pofitives ou négatives de pefanteurs fpécifiques qui feront 0.0006 multiplé par ce nombre de degrés, de maniere gue échelle de Varéométre eft en quelque forte attachée au thermométre qui s’ éleve ou s’ abaiffe fuivant le changement de température.

By MICHAEL KEARNEY, D.D. M.R.I.A. and of the Etrufcan Academy of Cortona. Tue origin of the art of expreffing the conceptions of the peay Dec. mind by vifible, permanent figns, hath at all times been an obje&t 12 1789 of curiofity. Cicero adduces the invention of alphabetic writing _ as a proof of the czleftial nature of the human foul. Many who have fpeculated on the fubje&, overpowered by a view of the utility of the art, and the comprehenfive fagacity which the formation of it implies, have afcribed its introduétion to the immediate infpiration of the Deity. ‘The Heathens, in this opinion, conformed to their ufual practice of affigning a divine author for every ufeful and extraordinary invention. But Chriftian writers have alfo held the divine infufion of this art, though there are different opinions concerning the time of the com- (A2) munication ; \ [4 munication; fome fuppofing it made to Adam; while others confider the promulgation of the Mofaic law as its era. With- out producing the pofitive arguments that may be urged againft this opinion, we may obferve, that it is unneceflary to have recourfe to it: for however inadequate the energy of any in- dividual human intelle& may feem to the completion of alphabetic writing in its prefent form; yet a fucceflion of inventive powers might have raifed it from the rudeft beginning to the moft aftonifhing excellence. ‘This appears to be now the prevalent opinion: yet though admirable ingenuity and erudition have been exerted in detailing the gradual expanfion of the art from its nafcent rudiments, feveral chafms in the progreflion feem to be ftill unfilled. To attempt the fupply of zhis deficiency, and to give a con- nected hiftory of alphabetic whiting, is the obje& of the paper now fubmitted to the confideration of the Academy. Tuat the propriety of the links, which I fhall venture to fupply, may be more clearly feen, it is unavoidable that I fhould trace the progrefs -of writing as far as Warburton and others have defcribed it. Alphabetic letters denote founds; it is however probable, that the firft ftep was a delineation of. the forms of things; the conception, not the words exprefling it, was what offered itfelf for communication, and it readily prefented a na- turally refembling, permanent mark. Here it may be obferved, that moft inftituted figns may be traced to others fuggefted by nature; thus articulate words marking ideas by compact were probably Cg od probably formed from the cries by which nature direQs us to exprefs our feelings. Hiftory confirms this account of the origin of the art; as pi@ture-writing has been found in ufe among many nations fomewhat raifed above the favage ftate, and not yet arrived at refinement. PiCture-writing was improved into a more artificial mode, and gradually paffed through the feveral hierogly- phic forms enumerated by Warburton with erudition and accuracy. He has followed the fucceffive fhades of hieroglyphic denotation, beginning with the rude eflays of piéture-writing, and advancing through analogy, emblem, &c. to the ufe of figns by inftitution or the arbitrary characters of the Chinefe. He juftly obferved that the earlieft fpecies of arbitrary characters, of which thofe ufed by the Chinefe feem to be a juft example, were probably derived from the hieroglyphic forms, and of this refemblance the Chinefe letters ftill retain fome faint veftiges. The likenefs continually declining by the carelefs delineation of current ufe, their affociation with the ¢hings fignified, which they now ceafed to exhibit to the eye, became weaker, while their conneétion with founds, their brother figns, grew ftronger; hence at length they feemed, and in fact became, folely reprefentative of them. Here Warburton ended. Monfieur Goguet, “ De lorigine des ~ Joix, des arts, &c.” advanced farther, and conjeGtured, that the next ftep in the feries was made by the introduction of marks. denoting fyllables, or the more compound elements of words. This mode of writing ftill prevails among the Ethiopians and fome Indian nations; and, according to Koempfer, in Japan. It is probable that fyllabical denotation fucceeded to verbal, as Monfieur Goguet has conjeCtured; but of this tranfition he has affigned ih a affigned no reafon. It feems to me, that it may be accounted for in this manner: we cannot fuppofe that writing was improved even to this degree of excellence before language was in fome meafure cultivated: but one of the firft artifices, that occurs in the refinement of language, is compofition or the union of diftin@ words in the formation of new terms, which the encreafed wants and enlarged ideas of men in the progrefs of fociety would require. To exprefs fuch compound founds, the marks of the feveral conflituent founds would be joined together. It was foon ob- ferved, that many of thefe ingredient founds were the fame with others non-fignificant, that has occurred as parts of uncompounded words, that is, as fyllables: hence was eafily fuggefted the artifice of denoting fuch fyllabic parts by diftin@ marks; the combination and varied arrangement of which would reprefent the numerous words of language compendioufly, without the multitude of figns which verbal notation required. To this fyllabic alphabet, it appears to me, that one entirely compofed of confonants fucceeded. The mind being now accuftomed to analyfis, the refolution of words into fyllables would in time be followed by that of fyl- lables into their component elements. But the variety of ~ fyllabic founds chiefly arifing from organic articulations or con- fonants; and the number of vowels or fimple breathings being few ; men would be contented to give marks to the firft, leaving the others to be furnifhed by the reader. This conjecture be- comes more probable, if, according to the opinion of Lord Monboddo, fyllables in the primeval languages contained, each enly one confonant. It is alfo fapported by, and accounts for. the nature of the Hebrew and fome other oriental alphabets, which Fi ora which have no charaéters denoting vowels, the Maforetic punc- tuation being novel. In all the weftern alphabets both con- fonants and vowels have letters appropriated to them; becaufe the art of writing was not imported from Afia into Europe, until the want of vowel, marks had been found to be incon- venient. The addition of fuch marks brought this wonderful art to its prefent ftate of perfeGion. \ . j97ot ; 9 f:.3 IQ Donets ay 4 ; ‘ | & refit: tit Be ot Broa’ sna , rd f | f] . r vt wate ilGay |: ; r : : 7 4 +o 1.20 ; “oun ead of.

By ARTHUR BROWNE, LL. D. Fellow of Trinity College, Dublin, Reprefentative in Parliament for that Univerfity, and M. RT, A. PREFATORY REMARKS. i, In philological difquifitions nothing is more difficult than Read Feb. . to exprefs our meaning fo precifely as to avoid all danger of 13? "79° being miftaken. It becomes neceflary, therefore, to premife and fpecify the fenfe which, in the following effay, is annexed to cer- tain terms often vaguely ufed. 2. Aorists, or indefinites, are fometimes fo called becaufe they are ufed for many tenfes indifferently, pafts, prefents, and futures. Sometimes, becaufe they do not mark any precife point of time when an a¢tion happened, but only exprefs that it did happen.. Sometimes, becaufe the verb when ufed in thefe tenfes doth not. expre/r whether the ation fignified be perfected or im- | (B) perfea. [ | perfect. In this laft fenfe only is the word applied in the fol- lowing treatife, as by definite is meant the tenfe in which the verb exprefies the perfetion of the ation. The reafon of adopting thefe definitions will appear in the fequel. * 3. Ir will be obferved that I fay, “ do not expre/s perfeftion ‘“‘ or imperfeGiion,” for it may be implied and yet the tenfe be indefinite. Thus Mr. Harris, in his Hermes, truly calls / wrote, and J wrife, indefinites; although the man who wrote has written, that is, the action is perfefted; and the man who writes is writing, that is, the a€tion is imperfe&t: but the perfe@ion and imperfeCtion, though it may be implied, not being expreffed, not being brought into view (to do which the auxiliary verb is neceffary), nor intended to be fo, fuch tenfes are properly called indefinites.. They may be called, if we pleafe, verbal indefinites ; but it is of thefe we fpeak; and if they be not indefinites, there can be no other in the fenfe which, as it has been obferved, is applied to the word in this treatife, and I think in common ufe, and by moft philological writers. 4. To illuftrate this definition ftill further by example. When Dr. Louth fays, that Z do, and I did, often exprefs the prefent imperfect and preterimperfe@t, I muft beg leave, with great de- ference, to differ from him. ‘They are indefinite. ‘* He loves “not plays, as thou do/f, Anthony,” does not direcily bring under our confideration or view Anthony’s continuing, or not continuing to love plays (though it may by implication), but merely his love for them, the affection merely, without calling our attention to Pe RS a to its perfection or imperfection. JZ do love, thou doft tove, arc exactly fynonimous to J /ove, thou loveft *. 5: Ir muft alfo be premifed that in the two laft fenfes, of the three mentioned in the fecond feGion, the word indefinite will fometimes have direcily contrary effects; if it marks not the per- fection or imperfe@tion of the aétion, it will oftentimes refer to a precife point of time, and the converfe. When I fay, J wrote a letter, 1 muft have been {peaking of fome particular time when I did fo; but when I fay, L have written to him often+t, I only exprefs that I have written at fome times antecedent to the pre- fent, but at what times does not appear. Thus the tenfes ufually called definites frequently refer to the paft time indefinitely. 6.5, 2: } The * Suppofe the queftion, do you ride the fame horfe you ufed to do? and obferve how - very different the meaning of the anfwer, J do ride him, is from that of the anfwer, Lam riding him. + Note, I wrote to him often, is not intelligible without referring to fome precife point of time, e. g. when I was in France. Why then does Dr. Beattie, in his late excellent work, (the Elements of Moral Science) fay, £ wrote, is indefinite, becaufe it refers to no particular part of paft time? No, it is indefinite becaufe the verb in that tenfe'does not define whether the aétion be completed or imperfeét. And why does he fay, I have written, is definite, in refpe& of time? for it refers to no parti- cular time at which the event happened. Put this further Example. A. fays to B. “ T wifh you would write to that man.” B. anfwers, «I have written to him.” The fenfe is complete. The expreffion is not fuppofed to refer to any particular time, and does not neceffarily elicit any further query. But if B. anfwers, I wrore to him, he is of courfe fuppofed to have in his mind a reference to fome particular time, and it natu- rally calls upon A. to afk when. Is it not clear then that, J wrote, refers to fome particular time, and cannot have been called indefinite, as Dr. Beattie fuppofes it is, from its not doing fo? Take another example. <‘* I have gone to plays,” does not relate to any particular period. * I went to plays,” muft mean at fome precife time, e.g. laf winter, or when I was in France. ‘Che author of the article Tems, in the En- cyclopedie, had fome ideas of this kind, when he infifts that the preterit ab/folu of the French has all the characters of an indefinite. \ fi eed The author therefore of the article Aorift in the Nouvelle Ency- clopedie fhould not have laughed fo unmercifully at Mr. Demandre for giving the name of definites to tenfes which marked the paft time zndefinttely ; “ an odd reafon,” fays the article, “ and Mr. “* Demandre fhould have underftood himfelf before he began to “© write.” Mr. Demandre’s ideas were probably clearer than the critic's; but he leaves room for the criticifm, by referring the word definite to time. If he had, with me, intended the word to mark the perfetion or completion of action, the feeming con- tradiGtion would have vanifhed. 6. To illuftrate this ftill further, Z wrzte, in one way of ufing the word, may be a definite, to wit, “ Iam a writer or author;” this is definite, for it expreffes imperfection, to wit, “ that I con- “ tinue to be fo,” but it immediately ceafes to refer to any precife point of time, though it does to the prefent epocha in general. On the other hand, J wrzte, the indefinite, meaning the mecha- nical at of writing, applies to this prefent individual moment, without exprefling extended time. 7. So in other examples given by Dr. Beattie, of what he calls prefent indefinites, (and what I would call prefent definites). “* God is good,” “ two and two are four.” Thefe propofitions muft ever continue to be true. The time of the exiftence of thefe truths never can be perfe@ly paft; therefore they do not refer to any particular time or part of time. 8. In the meaning which I have affigned to indefinites Mr. Harris agrees with me, though in a different mode of expreffion. . By [ire By an indefinite tenfe he means a non-extended time; by a definite, an extended time. Now the verb, exprefling the action, when ufed in its extended time or tenfe, expreffles the perfection or imperfection of that a@iion. When ufed in a non-extended time or tenfe, it expreffes neither. I diftinguifh the tenfes by this attribute or confequence: He by their intrinfic nature: It comes to the fame thing. But we both differ from Dr. Beattie, who means by zudefinites, tenfes which do not refer to any particular time; by definites thofe which do. Confequently he calls, Z write, a definite, whereas Mr. Harris calls it, with me, an indefinite. For the fame reafon, according to his fyftem, I think he ought to have called Iwrote, a definite, at leaft in many inftances; becaufe very often, to be intelligible, it muft refer to a particular time, as appears from the preceding note. J have written to him, is intelligible, without referring to any precife paft time, becaufe all it means to exprefs, is before the prefent time, but J wrofe is not intelligible unlefs fo referred: And therefore I cannot agree to his application of the word, which refers it to a particular part of time, becaufe, as it appears to me, it would fometimes make the tenfes ufually called aorifts, to be called definites. For example, in the Greek language, the fecond aorift generally refers to a particular time, and there- fore, in propriety of {fpeech, fhould change its name, and be called a definite: And befides, the fame tenfes might be definite or indefinite according to the words or fentences that followed them ; all which, though it would make no material difference in mental ° reafoning, would occafion confufion, by deviating from the com-- mon ufe of words. 9. From [ 16 ] 9. From the’ preceding Remarks it will by this time appear, why I have adopted the definitions of the words definite and indefinite, which are laft mentioned in the fecond fection; and why thofe names are by me referred to time through the medium of action, rather than to time immediately ; becaufe the latter method makes the fame tenfes definite or indefinite, according to accident ; the former keeps them invariably diftin@. The latter, if con- fiftently followed, muft occafion deviation from common ufe in naming the tenfes: The former will produce a conformity to it. It will, however, appear hereafter, that the application of the word to time immediately, does not affe@ the following theory *. 10. Ir it be objected that many verbs do not exprefs acfion, let the word event be fubftituted in the following pages, as it may without affecting the argument; e. g. perfect, or imperfect event, and the objeCtion is anfwered. * Vide note at the end of this effay. BRIEF BRIEF STRIGQTURES, &c. ‘Tue three great objects in the acquifition of languages are the knowledge of grammar, of words and their fignification, and of idiom or phrafe. Without accurate grammatical knowledge the two laft will form a very imperfe& linguift; and in the pro- vince of grammar the dodtrine of tenfes or times is evidently one of the moft important. For how ‘is the meaning of the au- thor or fpeaker to be diftin@ly and definitely known, without knowing precifely the time of which he fpeaks, and’ to which -the ation is referred? Such enquiries, therefore, though lefs refpeted than formerly, perhaps becaufe rendered lefs neceffary by the immenfe labours of the two laft centuries, have a certain utility, and have within the prefent age obtained the attention, and employed the induftry, of three celebrated philofophers, and moft ingenious inveftigators of univerfal grammar, Dr. Clark, Mr. Harris, and Lord Monboddo. the moft philofophic and univerfal divifion Mr. Harris has given us of time, from whence he argues that there are in nature twelve tenfes or: times. . Paft, I wrote. Inceptive. I was beginning-to write. Three Indefinites. Prefent. I write. Three paft Definites. Imperfect. I was writing. Future. I fhall write. - Perfect.

Perfect. 1 fhall be beginning, I fhall be writing. I thall have written. or going to write. Tuts philofophic divifion, as Lord Monboddo truly obferves, has never taken place in any language with which we are acquainted; but it feems univerfally acknowledged that the Greek in this, as well as in many other refpeéts, may challenge a pre- ference to moft if not all languages that have ever been formed. In the Greek a@ive and middle voices there are eight tenfes, and in the paflive nine, which, if you ftrike off Mr. Harris’s inceptive tenfes, whofe utility I do not well fee*, comes very near to his philofophic number, nor do they much differ from his univerfal tenfes in fignification. This merit, however, of the Greek language, Lord Monboddo has endeavoured, though with- out avowing fuch intention, to depreciate, by boldly ftriking off : two of thefe tenfes, and by roundly afferting, and calling to his aid, the affertions of fome ancient grammarians, that the fecond future and the fecond aorift mean nothing different from the firft * Take Mr. Harris’s example. « Ido not well fee how they can be called tenfes of the verb #e write; they are tenfes of the verb ¢o ga, or to begin, joined with the infinitive to write. I do not clearly apprehend how one compound tenfe can be made out of two verbs, unlefs one of them be a mere auxiliary. Scripturus ero may be a tenfe; but will it be faid that Snoev yap iusarv, Lib. 2d, Iliad, line 39, is a tenfe of any verb? If it be, of what verb? It may be a tenfe of philofophic grammar, but not of the grammar of any particular Janguage.” hs] firft tenfes of the fame name, and are only oid obfolete prefents and preterimperfects, preferved after the verb was modernifed, merely to vary and enrich the found of the language +. Ir may well be doubted whether varying founds without va- rying the fenfe can ever be an improvement of language; but no man will deny, that if thofe various words have diftin® meanings, not only the variety of founds will remain the fame, but the language will be more definite, accurate, and perfect, and the various turns and ations of the mind or body will be more clearly and certainly expreffed. To try whether the Greek language may not be refcued from this imputation, for fuch it may be confidered, of having diftin@ founds without diverfity of meaning, is the object of the prefent effay, which is not fo ‘much propofed in the light of a fyftem as of an enquiry. In purfuing this enquiry, it muft be premifed that we are not to expect to meet with any rule that can be adopted with refpect to the meaning of the Greek tenfes, to which numerous “exceptions will not occur. In truth the Greek writers ufe them all in common prac- tice fo promifcuoufly, that it feems hard to fay to what philo- fophic time they have not applied every tenfe of grammarians (C) upon | + If that was the cafe, it would have been incumbent on Lord Monboddo to have fhewn how they came to be ufed for futures and aorifts, and not, as they naturally would, for other expreffions of the new prefent and preterimperfea. [ 20 ] upon fome occafion or other*. But that does not prevent an enquiry, whether they were not meant originally to exprefs dif- tiné& and fpecific times, and whether they are not more fre- quently ufed according: to thofe original meanings than to any other. To begin with the aorifts. That the aorifts are often ufed without difcrimination as mere paft indefinites, cannot be denied; but this is true alfo of the preterimperfec, and of the preterplu- perfe&. They are frequently ufed as paft indefinites, but no man would venture to fay, that the two laft are therefore not diftint tenfes, having proper and original meanings of a definite nature, as I think has alfo the firft aorift. The queftion is not what takes place in practice. This may arife from abufe, from negligence; for we may be fure that the beft Greek writers, as well as the beft Englifh, are fometimes negligent; or from the neceflity which the poets felt of accommodating the length and - fize * Wyoodxeote, ufed as a future. Bf{chines cont. Ctes, fec. 8th. Mereywoar, dysvorze, ufed as preterpluperfeéts. Dem. de corona, fec. so. In the 11th book of Homer, line 296, #€:¢rxs, ufed as an indefinite, though a preterpluperfeét. Every one knows that aorifts are often ufed as prefents and futures. Thefe inftances, out of ten thoufand, happen at this moment to occur to me; but they teem in every page of every Greek author ; nor is it_poffible to mifs them. It appears to me, however, and it may well afford matter for furprife, that the more ancient authors, and particularly Homer, are more nice and difcriminating in the ufe of the tenfes than the more mo- dern; and that Dr. Clark could not haye found any book that would have fupported his analogy of the tenfes nearly fo well as his and the world’s favourite author. Lan- guages certainly advance gradually to perfeCtion; but perhaps in fimpler times there is, if I may be allowed the expreflion, lefs luxury and wantonnefs in the ufe of language as of every thing elfe; or perhaps the ufes of life do not require fuch various appli- cations of it. HY : Led fize of words to the metre and ruthmos, But the queftion is, whether the aorifts are not in ftri&t propriety diftina, as to figni- fication, and were not meant originally to be fo, and even whe~ ther one of them may not have fignifications incommunicable to the other. I ruinx then it cannot efcape our obfervation that the firft aorift has much more frequently a definite meaning than the fe- cond. The fecond appears to me, in nine inftances out of ten, \ to be ufed indefinitely. He went, he rofé, he /poke, and all fimilar phrafes, are ufually expreffed in Greek in the fecond aorift, én, evecn, 27. ‘There is no difficulty in finding inftances to the con- trary; asin Tenth book of Homer, line 556, Neftor, fpeaking of the horfes of Rhefus, fays, I have never feen, nor have I obferved them before, enw io 28° evéyow.

I neither /aw, nor have I obferved. I neither recetved, nor have I expended, [Vide fec. 3, prefatory remarks.} Such diftin@ions are arbitrary, and therefore perhaps not generally noticed, yet they are not ufelefs, nor without beauty. Dr. Gregory, in a treatife on moods, in the laft Edinburgh tranfaGtions, takes notice of this very contraft, and ob- ferves ‘* that there is a precifion and beauty in this ufe of the fimple, contrafted with s* the compound paft tenfe, (e.g. the Lord gave and the Lord hath taken away) not to “be attained in Latin, which would fay Dominus dedit, and Dominus abftulit; but “‘ attainable in Greek, by ufing the aorift for gave, and the preterperfe&t for hath “ taken away.” No, not according to my idea; but by ufing the. fecond aorift for gave, and the firft for Aath taken away. The contraft of the fecond aorifts bearing fuch poflible conftruction appears in every book and every line; but Dr. Gregory has given no example of the contraft he mentions, as Iremember. Perhaps, after all, , é the if pe) and éaw€ey appear to have a definite fignification, but fuch inftances are comparatively few. The tirft aorift, on the contrary, is moft frequently ufed as a paft definite; and indeed fo frequently, that srammarians obferve it is oftner introduced to denote the paft perfe&% time than their preterperfe& tenfe itfelf. Have we not reafon then to fuppofe that its proper meaning is of a definite nature, and that it is not proper/y an aorift? Sanctius feems to have been of this opinion when he calls the fecond only by the name of aorift. And if it can be fhewn that fuch a tenfe was actually wanting in the Greek language, to exprefs the time of an ation which is paft and perfect, will not the truth of the pofition be ftrongly confirmed? In fhewing this, in faé& it will require more pains to diftinguith the firft aorift from the preterperfe& than from the fecond. Havine then diftinguifhed the firft from the fecond aorift, by arguing that the firft is not proper/y an aorift, and that where they feem to be ufed in the fame fenfe, either fuech a contraft as Dr. Gregory alludes to is intended, or it arifes from neceffity in de- feGtive verbs; I proceed tu fhew that fuch a definite, as I conceive the firft aorift to be, was wanting in the Greek language, and is not fupplied by the preterperfea. Tue tenfes of vulgar and philofophic Grammar frequently . differ, or, in other words, the times which common grammarians fup- the only inftances in which the Greeks ever ufe the fecond aorifts thus, -without ap- parent diftin€tion from the firft, are where they are the fecond aorifts of defective verbs, which have no firft aorifts, at leaft in common ufe ; ae a bie. fuppofed to be denoted by the written tenfes of a language, and according to which they therefore denominated thofe tenfes, are not the real times they were intended to exprefs. Thus Dr. Clark has proved, in the Greek language, that the tenfe ufually called by them the preter or paft perfect, does not properly exprefs fuch a time, but a different one, which ought to ftamp it with a different name*;, that the time it was intended to exprefs is complex, including the confideration both of the paft and of. the prefent; and implying, that the ation has been done, and ftill con- tinues to be done. ApgiGsCyxas; thou haft proteéted, and doft full protect. Tebavuaxes; thou haft admired, and doft ftill admire. This opinion is confirmed by the authorities of many other of the moft able linguifts, particularly Lord Monboddo and Mr. Hunting- ford. i Tuis then being in ftritnefs of f{peech the true fignification of the preter tenfe, ufually, though improperly, called the pre- terperfe&, it is plain that we muft feck in the Greek lan- guage fome other tenfe, to exprefs the time of the perform- ance of an action which was perfected at a time paft, and has ceafed to continue; whofe conclufion was antecedent to * The appellation he gives it is the prefent perfect. In this appellation I muft beg permiffion not to concur with him, becaufe whatever is perfected muft be paft.. Non meus hic fermo. Scaliger had heard the name, which did not originate with Clark, and laughed at it for the fame reafon, for whatever action or paflion is ftill continuing muft be imperfect. Some name is wanting to exprefs this compound of the paft and prefent.. E pat to the prefent time, and which bears no other relation to the prefent, and whofe time therefore is the real preterperfect. Accord- ingly Dr. Clark has afligned to this office the tenfe ufually called the preterpluperfect ; but furely without authority, for that tenfe exprefles fomething more. The tenfe we want is only to denote that the action was paft and perfected at a time antecedent to the prefent. But the preterpluperfect is always ufed to fignify that the action was paft and perfected at a time antecedent alfo to a paft time, i. e. antecedent to fome given period or epocha paft, to.which we look back. He bud done it, fecerat, muft mean that he had done it before fome certain time or event paft, of which we have been fpeaking, and is fomething very different from faying, be uAs done it, Grammarians were therefore in this inflance right in calling it the preterpluperfect, as implying fomething more than the mere paft perfect. This tenfe then not anfwering our purpofe, it feems to me that we mutt have recourfe to the firft aorift, and that the original intention of the firft aorift was to exprefs the real preterperfect time of philofophic grammar. To confirm this by examples would be an endlefs tafk; the only method of proof that can be adopted, is that of referring the reader to the general ufe of this tenfe when it is not an in- definite. When it is ufed as a paft definite it can have but two meanings ; either that of an action entirely paft, or of an action which commenced at a time paft, and is ftill continuing. The latter meaning has been appropriated by the writers abovemen- tioned to the preteritum perfectum. It follows then of courfe that ah bao eee eee [i er that the former belongs to the firft aorift. Exceptions * to the general rule cannot be allowed to fubvert it, for if fo the multi- tude of exceptions + to Dr. Clark’s and his followers eftablifhed interpretation of the preterperfeét muft overthrow his fyftem. The one feems equally {trong with the other. Have I explained my argument clearly? it is, that a peculiar fignification having been proved inthe preterperfe@, vulgarly fo called, viz. that of a continuing aQion, and there being a phi- lofophic time belonging to an action quite paft, and not now continued, there ought in vulgar grammar to be a tenfe exprefling fuch atime, and in Greek no tenfe can be found applicable to it but the firft aorift, which undoubtedly often expreffes a paft definite of fome kind or other, and therefore, without any force or violence, naturally falls into that place. When it expreflesa paft definite, it muft mean either an action quite paft, or partly paft, but ftill continuing. In the latter meaning it would be confound- "ed with the preterperfect, from which danger Dr. Clark has refcued itfor me. It remains therefore clear that the former mutt be its meaning { THE *JIn the two: firft words of Xenophon’s Memorables, is an exception, HOAAAKIZ iSatuaca,, where the furprife of. Kenophon certainly had not ceafed. But fuch excep tions are few. A ‘ + That fuch exceptions are numerous may eafily be feen, by cafting the eye over the firft twenty pages of Demofthenes de Corona, where the preterperfe& tenfe is very frequently ufed, not in Dr, Clark’s fenfe. { Tt will be faid here that I have been employed in diftinguifhing the firft aorift from the preterperfect, and not from the fecond; and it will be afked, how does it appear fate] THE argument is ftill further confirmed by Lord Monboddo’s extenfion of Dr. Clark’s theory of the preterperfeé. In the total inefficacy of the preterperfett of grammarians to exprefs the real paft perfect time, Lord Monboddo agrees with me, though not in the mode of remedying it. He draws a ftill more accurate line about the preterperfect than Dr. Clark, and endeavours to fhew that in every inftance that tenfe is compound, and relates to the prefent time. The apparent exceptions to Dr. Clark’s idea of its exprefling a continuing action, he removes, by infifting that in thofe cafes it is made ufe of becaufe the effects and confequences are continued to the prefent time; and that whenever it is ufed, we fhall find, either that the ation or its effets are continued to the prefent time. ‘ There are actions, fays he, ‘ which end in energy, and produce no work that re- ‘ mains after them. What fhall we fay of fuch ations? cannot ‘ we fay, we have danced a dance, taken a walk, &c. and how * can fuch actions be faid in any fenfe tobe prefent? My anfwer * is, that the confequences of fuch actions, refpecting the fpeaker ‘ or fome other perfon or thing, are prefent, and what thefe * confequences are, appear from the tenor of the difcourfe; I « have taken a walk, and am much the better for it. I have danced * one dance, axd am inclined to dance no more. So in Demof- ¢ thenes’s oration againft Ariftocrates, whom he accufes of tranf- ‘ grefling a decree, when he confiders the tranfgreflion of the * decree appear that the fecond alfo may not exprefs this paft and perfect a€tion ? The anfwer is, that we fet out with fhewing that it failed in exprefling the perfection of the action. ‘The preterperfeét does not exprefs that it is zotally paf?. The fecond aorift does not exprefs that it is perfected. The firft aorift. alone expreffes both. fay 4 ‘ decree as prefent by its effets and confequences, he ufes the * preterperfect, wapaCeCyxe, he has tranfgrefled. If he confiders the * tranfgreflion fimply as paft, he ufes the aorift aepeCy.’ Havine thus confined the meaning of the preterperfect to a conipound fenfe, which always has a connection with the prefent, -Lord Monboddo naturally proceeds to fupply tenfes for the paift, i. e. for that paft which has no conneGion with the prefent. This purpofe he confiders as an{wered by the aorifts, ufed indefinitely, and without diftinction—e. g. he /poke, he fad. But he forgets that thefe tenfes, in the meaning by him affigned to them, fignify only the paft indefinite, and that he has not pointed out to us any tenfe, which may exprefs the paft perfect. Either therefore he muft affert that there is no paft perfect in nature, unconnected with the prefent, (which would contradiét his previous divifion of the paft into perfea, imperfea, and indefinite) or he muft allow that he has omitted to fhew any correfpondent tenfe in the Grecian grammar. Indefinites only exprefs that the action is paft, but fay nothing about its perfeétion; whereas we want a tenfe to exprefs both that it is paft and perfea . Bur to prove further, that indefinites will not fuffice, as Lord Monboddo feems to fuppofe they will, to denote that pa/? which excludes the prefent, we muft obferve that the fpeaking of an aQlion (3D.;.) merely * If thefe expreffions offend, viz. of tenfes or times exprefling the perfection or im- perfection of action, let it be remarked that they are only ufed for the fake of brevity, and that the reader is always fuppofed to fubftitute my original definitions of definite and indefinite tenfes, viz..thofe in which the verb expres the perfe€tion or impets_ fection of a€tion; or we may with Dr. Beattie fpeak of the tenies as perfected or imperfect with re/pect to action. * [ 28 ] merely as pat, i.e. indefinitely, does not exclude the prefent: it may be in part paft, yet fill continuing and we may be {peaking of that portion which is paft. He /poke we//, does not imply that he may not be fpeaking ftill: It may only mean that he {poke well during that part of the fpeech which the relator happened to hear. But when we fay, he has been a good fpeaker, we exclude the prefent, and evidently exprefs that he is no longer fo. How would indefinites anfwer this purpofe? Lord Monboddo himfelf takes notice of this diftinGion in Latin. “ The Latins, fays he,” “ have a mode of “ fometimes ufing their preterperfe@t, in a fenfe which pofitively “ excludes the idea of the prefent time.” « Fuit Ilium, Fuimus Troes.” VIRGIL. “. Vivite felices, memores & vivite noftri, * Sive erzmus, feu nos fata fuiffe volent.” TIBULLUS. He obferves at the fame time that the Latin language was probably derived from the Greek before the Greek had arrived at its greateft improvements, and before it had been enriched by a greater variety of tenfes, and therefore has no aorifts. Ir this be true, do not his obfervations make it probable, that after the feparation of the Latin language, the Greeks had furnifhed theirs with the firft aorift, for the very purpofe of expreffing, by a feparate tenfe, this exclufion of the prefent time, as they fur- nifhed it with the fecond aorift to exprefs the mere pure inde- ‘finite ? Bur a es oe [Sip Bur allowing Lord Monboddo’s extenfion of Dr. Clark’s theory to be too refined; as many have fuppofed it to be, and that the exceptions to Dr. Clark’s explication of the preterperfect are as numerous as they feem to be, and that it often means an aétion entirely paft and difeontinued, even in its confequences; give me leaye to hazatd a conjeture, that even in this cafe it is diftinguifhable from the firft aorift, and that this tenfe has ftill a peculiar meaning of itsown. ‘“ The difference between the preter- - « perfect, and the aorifts,” fays Mr. Huntingford, ‘‘ is that which we “ underftand when we fay, ] have written yeypaa, and I wrote "© Eyoatbe. It is fo when this aorift is ufed indefinitely, and in fuch “ cafe the diftindtion equally applies to the fecond. But we are “ now fpeaking of cafes where it is ufed definitely, where they “ both fignify, J have written, and in fuch cafe fome grammarians, " as is obferved in the Port Royal Grammar, have conceived the “ difference to be, that the firft aorift denotes a time very Jately pa/?, “ the preterperfect, ove long face,” ~ It is with much deference that I propofe an opinion. dire@ly oppofite. Let us fee, by a few ex- amples out of many which have occurred to me, whether there be not fome ground for this opinion, having firft ftated clearly what the opinion is*, . (D2...) In * The author of the article Tems, in the Encyclopedic, obferves that fuch dif- tingtions are poffible, and therefore ought to be noticed in treating of univerfal gtammar, though he does not know whether they ever have taken place in the grammar of any particular language, I think they have in French as well as Greek, in their preterit abfolu and preterit -indefini. Pere Harduin fays fuch dif- tinctions are arbitrary. Be it fo; their exiftence is not thereby difproved. The dif- tin&tion above-mentioned between the aorifts, (viz. that of the contraft obferved by Dr, Gregory between the fimple and compound paft,) is certainly arbitrary, depending on expreffion in words, not on the nature of things; yet, though we can from thence account for the diftinGtion having efcaped general notice, we are not thereby autho- rifed to deny its exiftence, [5 go] In the Latin anu Englifh languages we have no diverfity of tenfes, or of fingle words, to exprefs whether a paft ation has been done lately, or a long time fince. It is only from the tone of the fpeaker, from the circumftances of the event, or from the context, that we can find out the difference. I fave done it, fect, does not tell us whether it was done this inftant, or in the com- mencement of the fpeaker’s life, fifty years ago. But if the agent enters in hafte and perturbation, and fays, I have done it; from his looks and accents, and the circumftances of the time, we colle@ that he has done it the inftant before: it is the prefent perfec. If, on the other hand, he fays, J have done fuch things in my youth, we know that there is a confiderable interval between the doing of them and the prefent zra. In the paflive, the difference is manifefted in words, zt zs done, it has been done, but not fo in the active. To fupply this defe&t, which the Englifh and Latin languages labour under, in their active voice, in not diftin- guifhing, by different founds or words, the difference between what was lately perfected and what fome time ago, and in the paffive, in not making this diftin@ion but by the help of the auxiliary verbs, the Greeks feem to me to have invented their firft aorift, and to have intended by it to indicate the latter, as the preter- perfe& did the former. Tue opinion of Theodorus Gaza, as quoted by Lord Monboddo, with refpe& to the meaning of the preterperfect, in fome meafure coincides with this theory, which is alfo ftrengthened by the obfervation made in the effay upon the origin of languages, that the preterperfet was called wapaxeievoc, as being a time near to the prefent. But without relying upon this argument, I fhall proceed a if eatue proceed to produce fome examples tending to fhew how far this fuppofition correfponds with experience. Wuewn Archimede rufhes out of the bath, after making his celebrated difcovery, he cries out eupyxe, becaufe he had juft at that moment found out and folved the difficulty. But when Neftor fpeaks of ancient days and ancient heroes with whom he had been converfant, he fpeaks in the aorift, dgcfoow nemep uliv Avdpacw «pidyse. 1 Lib. Homer, line 260 and 261. Wuen Demofthenes fuppofes the queftion rebvyne Dircrzos ; it follows plainly that if the fact had been fo, and any perfon had come in fuddenly to announce it, he would have faid refmxe. But when Chryfes, in the firft Iliad, line 40, alludes to actions by him formerly and frequently performed, he ufes the aorift, 7f Z have ever crowned your altars or burnt uittims, epee and exo. When /Efchines concludes his oration, with calling Heaven to witnefs as to his own efforts in the progrefs of it, he ufes the pre- terperfet, becaufe thofe efforts had juft then been made, CeConiyna ua eigmrice. So Demofthenes, in multiplied allufions to the calumnies juft beforé thrown out againft him by Aifchines, ufes the preter- perfe, PeCraconunxe mepe eue. Nor perhaps is it an objection that Demofthenes, in the fame oration, fpeaking to the Athenians of his own life and adminiftration (much of which had long fince elapfed), fays — and wemodrevpa:; becaufe as he was Still con- tinuing to live among them, and /7// to adminifter their public affairs, he {poke of matters not entirely paft. So Demofthenes, in the 36th feGion of the fame oration for the crown, fays, Tregavaccay|ww il ea 4 of tis “iva & Ereparveagcivjov rolvy vay ene emt relos tore, wou yecbaijos Agicovicy rae wag cvAAabes as mep overt Kryowgav vo syéloume, Tue crowns to which he alludes were given formerly, rere; the participle of the firft aorift is ufed, Lrepavwccaijav ; Ctefiphon’s is comparatively recent, wv, therefore he ufes.the preterperfed yeloape. So in the CEdipus Coloneus of Sophocles, the Chorus, fpeaking. “of the death of CEdipus, which has juft happened, fays PeCyxev, More examples would be tirefome; thefe may be fufficient to draw the attention of the reader to fimilar paffages, Ir muft be acknowledged that im the very next page a con- trary inftance occurs, The Chorus. afks, again, Finiit Vitam ?.

[os Ul yield immediately to fome contrary inftances, which may be owing ‘to inattention or poetic licenfe ; and I muft again recall the reader’s attention to this truth, that if fuch weight be given to contrary inftances, neither the interpretation given by Dr. Clark, and all the eminent Greek fcholars of this century, of the preterperfect, nor indeed any fyftem calculated to reduce the Greek tenfes, to fome certain and clear analogy, can be maintained. Nothing is more common than a primogenial and a vulgar ufe of words, of tenfes, moods, &c. Itis the cafe, as Dr. Clark has fhewn, with refpect to the preterperfe@. It is the cafe with refpe&t to the middie VOICE ; its primogenial ufe, as is univerfally acknowledged, is to mark a refle@ted ation, like! a reflex verb; yet how often is it ufed without any fuch poffible meaning? Why may not, in the fame manner, a primogenial fignification and ufe be granted to the firft aorift, though contrary inftances occur? The weight and number of inftances is to determine a Tue probability that the Greek language might entertain a diftin@ tenfe to denote what had lately or what had long fince happened, is augmented by our knowledge that they had a tenfe to exprefs what was foon to come. The nation that ufed a paz/o poft future might have a paulo antepretertt. Some circum ftances refpe@ting the French language may tend alfo to illuftrate and * In affuming this criterion I am fupported by Cafaubon, Vofhius, and Henry Stephens. Notwithftanding numberlefs oppofite inftances, they advanced an opinion that the firft aorift denoted a time lefs remote than the preterperfect did; this being an opinion dire€tly contrary to mine, I might be thought guilty of great prefump- tion, if Henry Stephens, from whom the opinion originated, had not latterly expreffed great doubts of its truth. ee? ae and to confirm the conjecture. They have two preterperfedts, one of which is ‘in fact an aorift. All their grammarians fay that this laft is never ufed if the time be not entirely paft; for inflance, ‘ il a été heureux cette femaine, ce mois ci, cette année.” “He was happy this week, this‘ month, this year ;” not “ il fue “ heureux,” though that expreffion would be applied to the hap- pinefs of the laft week, “ il /wt heureux la femaine paffée.” So they obferve it never is ufed to exprefs an action done the day we fpeak in, but one done always at fome fmall diftance of time; for inftance, they do not fay, to exprefs the happinefs of this morn- ing, ‘“ Je fus heureux ce matin,” but “ J’ai ete heureux ce matin.” “The fpeaker would not fay, “ { eat a chicken this morning,” but “ T have eaten,” “ J'ai mangé un poulet ce matin.” This is men- tioned only to fhew that diftin@ions of this nature are not chimerical, but do exift in languages. But whether this conjecture be well-founded or not, if the former pofitions be admitted, as I think they muft, that the fecond aorift is rarely ufed definitely ; that the firft is fo frequent- ly ufed in that fenfe, of a paft definite, as to occur oftner than the preterperfect itfelf; and that this laft tenfe having affigned to it a fpecific and appropriate meaning, there naturally remains for the firft aorift a proper and peculiar fignification belonging to it in ftri€tnefs of fpeech, though not always fo applied in com- mon ufe; I fay, if thefe pofitions be admitted, there will re- main a confiderable diftin@ion between the two aorifts. Tuere is fiill, lapprehend, another perceptible diftinGtion in the ufe of thefe tenfes. If an ation be fpoken of which has been often done, I think it is obfervable that the Greeks generally ufe the firft [ 35 ] firft aorift. Thus, in the beginning of the Cyropedia, where Xenophon refle&ts how many democracies have been * reduced, and how many oligarchies fubverted, cafes frequent in human affairs, he ufes the firft aorift; fo in the beginning of the Me- morables, Xenophon expreffes his frequent furprife at the errors re{pecting Socrates, J have often wondered, in the firft aorift; fo in the example above-mentioned, Neftor, wifhing to exprefs that he often converfed with men much fuperior to thofe of the prefent day, fays apayra; fo in fimiles where the comparifon is made with fomething frequently occurring, the firft aorift is generally ufed. E.g. the fimile ufed by Demofthenes, de Cor. fec. 57. “as if wef fhould blame the mariner who has prepared, &c. &c:’ is expreffed throughout in this tenfe. We may obferve that in thefe and fimilar cafes, we {peak of no particular time at which the a€tion happened, but only of an a@ion which has often paft, without determining any precife time. The fecond aorift, therefore, which generally refers to a particular time, is, I believe, feldom if ever ufed to denote a frequentative ; although Lord Monboddo has affigned this office to it, as well as to the firft, (E) ‘from * Evvore mob” npaiy Byévelo coms Onpuox paclices xdiertoncar tad tar ZAAws wus Curontrer morilstscbas v ” > « ry a7 * PaAAod ney One’ upallia, tour tr ah pwovcepre becky Gras Te dAvyapyice dvnpnilas 240 vse Onpaur. xab dos oe , Ae f Tupcervvely Eminerpnoailesy of ply aUTAY Ker Tox) mame KaleAvencaD, a Here a preterperfect is introduced among the firft aorifts, perhaps on account of the vicinity of the word 2d%3 which brings the view to the prefent time, figuifying Jam, abhinc—before the prefent day. : ’ “3 t Qomeg ay th rig vedurngoy wayt mt oulngia weckaila, net wacr xolaonsvacaila rd wAoior; ED av dmerdpCare cwliccolary cirm xeyauns Xenoapavory Kat moneda ale ter oxevaV, 7% Had (3 q 4 ~ s >_ - CuvTeicevlay OAws, TNs VaLOyIaS abTIOTO, haga A from which latter alone, however, he draws his examples. In like manner the French exprefs cumulatives by one of their preterperfects only, viz. the compound, (the other, as I conceive, correfponds with the fecond aorilt of the Greek,) and fay, “ Jai ** parlé de vous trente fois en ma vie.” Ir is eafy to produce apparent examples. to oppofe this theory. E. g. * in the fimile in the third book of Homer, line 23, it will be faid the aorifts are ufed indifferently, in an inftance fimilar- to thofe mentioned above. I deny it; enganon is not ufed there as a paft tenfe at all; it is ufed for the prefent, as this aorift frequently is, and the line ought to be tranflated thus : “ Asa lion rejoices who has fallen upoma large prey.” If it be doubted, take Virgil’s tranflation : “ Impattus ftabula alta leo ceu fepe peragrans “ Confpexit capream, aut furgentem in cornua cervum, 2? “ Gaudet hians immane—— fineid. 10, 723. In the fame manner, in the famous fimile at the end of the 8th book of Homer, ‘Qs 3 oF ev weaves dcee, various tenfes are ufed in defcribing a beautiful night-piece, fuch as has been often beheld; but they are all ufed for the prefent tenfe, and Dr. Clark | tranflates them accordingly. My pofition only is, that when on fuch * "Ose Atay txapn peyarw ind Camas xvpoas. E97.) fuch occafions a fa/, but indefinite time, is to be exprefled, the firft aorift is generally ufed*, THE diftinction that I mean to imprefs (I repeat it again) is this, that the fecond aorift is the only proper indefinite ; that when it is introduced as a definitef, it errs from its primogenial ufe; that it is even doubtful whether it ever be a definite, at leaft verbally} or exprefsly, though it may by implication—That, on the contrary, the primogenial ufe of the firft aorift is to exprefs a paft definite, and of a peculiar nature, viz. an action totally paft, and not now continued, wherein it differs from the preterperfect ; that the fecond aorift, even when it is ufed definitely, if it ever be fo, only fhews that the adion was perfected at a time paft, without determining the time when it was done, whether a long or a fhort time fince ; whereas the firft aorift, when ufed in its ftri@ (E.2) and “ If definite and indefinite therefore be referred to time, the firft aorift is indefinite, “ the fecond definite. If to action (in which manner it has been applied through this treatife) the converfe takes place.--Vide Prefatory Remarks, Section 5. + Quere, whether it ever is properly a definite, for I fearcely remember an inftance where it may not be conftrued indefinitely; for inftance, where id» and iaaGov are con- ftrued, I have feen, and I have taken, it would be as eafy to tranflate them, J /aw, and I took.

LET us proceed now very briefly to confider the two future tenfes of the Greek language, on which a very few obfervations will fuffice. Dr. Clark diftinguifhes between the two futures, by calling the firft the imperfect, and the fecond the perfect, which are thus by him enunciated, cewabo, I thall be fupping ; canavero, I fhall have | ! ae ae have fupped *. Lord Monboddo, though he does not perfectly accede to his tranflation of the firft future, which he fays is an indefinite, does to that of the fecond, and thereby allows there is a diftinétion in Latin, but denies it in Greek. “ The Greeks,” fays he, “have no one word to exprefs the future perfect or “ imperfect; their fecond future does not do it; both futures are “‘ merely indefinite ; if they wanted to fay, / /ball write, they could “ exprefs it by one word, the future of ypagw; but if they wifhed * to fay, J /hall be writing, they muft ufe a circumlocution ypaguy “ ecouas, and if they wifhed to fay, J /ball have written, they mutt fay yeypapws ecouat. I challenge (fays he) any perfon to fhew that “ canabo ever means, J /hall be /upping, in any author.” [I fhall not difpute with him about his meaning of the firft future, though I do not accede to it; let it be indefinite or imperfect, J /ball /up, or I fhall be fupping : if the fecond future be a perfect, and a definite, and fignifies,, J /hall have fupped, or I /hall have written, the diftinGtion will be fufficient. But before I endeavour to. fhew that it does, let me take notice of the pofition that the future. definite, that is, the perfection or imperfe@tion of the future, cannot be expreffed by one word without circum- locution. Now the fact is that the future perfect is very fre- quently * Tul, I fhall be beating. Tums, I fhall have beat. + To make good his challenge, Lord Monboddo fhould have defied us to fhew that the fecond future ever has the laft-mentioned fignification ; and if I thew that it has, the futures are thereby diftinguifhed, and his triumph over Dr. Clark is incom- plete. ee ee quently indeed exprefled by one word, in the infinitive mood ; for inftance, the prayer of Agamemnon, in the fecond book of Homer *, line 412. ) Zev nveise, peyist, nerawees, ouiDe pe veeka, M4 mel tr yeAsov uve, Kas Eh uvedag Erbe, TIpiy pee Kare wpnves Cordéew TIpsctpeouo perabpov AiSaroev, pyar ots Os aupos Sytoro Dupe|px. “Exrépeov do yurava weph srferos datzas, Xaduw pulecrtov montes 0 aud’ avroy eraipos TIpyvées ev xovinow obae AaCoialo yalcy t.

In truth, there is no difficulty in finding in- {tances, except in the indicative mood; and really one would imagine that it was that mood only that Lord Monboddo took into view. Now it muft be confidered that the future perfect of the indicative, J /hall have firicken, I fhall have fupped, can fcarcely offer itfelf to ufe but in dialogue or in oration. And this may be the reafon why it is feldom obferved in that * Let not the fun fet, before that I /ball have levelled to the ground the flaming palace of Priam, &c. &c.

Demofthenes does ufe the expreflion, yypaQus ivopas, but not of neceflity. 2 aad that fenfe, becaufe, though it may occur in common conver- fation, it can feldom be met with in the perpetuum Carmen, or perpetua Hiftoria; and when it does occur in dramatic writers it is exprefled in various ways; e.g. by the participle and genitive cafe, é rorouroy edrmidwv cue GeCwros, cum eo fpei pervenero, C&dip. Tyrann. line 781; but fcarcely ever by that circumlocution which Lord Monboddo defcribes. But the future perfeé that moft generally occurs, is that which is preceded by and depends upon fome adverb or conjunction, e. g. WHEN he /ball have “done-it, AFTER he -fhall have done it, and therefore throws’: itfelf into the fubjun@tive mood ; and in that mood there is no difficulty in finding inftances in abundance of the fecond future being ufed as a future perfett; e. g.* WHEN you /hall have come to the end of life, xwrav eg TeAog te Cyv apn, the verb is the fe- cond future conjun@tiive mood.

I am not ignorant that Mr. Dawes, in his Mifcellanea Critica, has totally denied the exiftence of the fecond future in any mood whatfo- ever, of the active and middle voices of the Greek language. _ With refpe& to the fubjun@ive mood, I hope the preceding obfervation is an anfwer.

THESE inftances may fuilice to lead the reader to attend to others; they may be found in abundance. Thus much in de- fence of Doctor Clark’s explanation of the fecond future. Nor can I acquiefce implicitly in Lord Monboddo’s tranflating the firft always indefinitely. When Antigone fays, in the Cidipus Coloneus, whether exiled in foreign lands or wandering over the feas, duoacev eZousy tpoezv, I do not fee why we have not as good a right to tranflate it with Dr. Clark, we /ball be leading a mi- ferable life, which is the future imperfect, as with Lord Mon- boddo, we /ball lead, which is indefinite. The former, though it may found inelegantly, appears to me the true tranflation. Havine thus fubmitted the few obfervations which occurred to me on thefe tenfes, let me not be fufpected of enter- taining the leaft inclination to detract from the reputation of Lord Monboddo, as a profound and accurate linguift. I agree with Mr. Huntingford in thinking that his work on the Origin of Language, is a work of the greateft penetration, erudition, and tafte; and the Greek fcholar is particularly indebted to him for the chapters relative to the Greek language; but I truft we may be indulged, without offence, in thinking that his fentence on the aorifts and futures was hafty and unfounded ; and if a favourite hypothefis fhould have mifled its author, and [+43 ] mt and fhut his eyes to invincible contrary examples, fome hints may poflibly be offered by this difcuffion to the minds of others, which may tend to elucidate and afcertain the analogy of the Greek tenfes. To fix their meaning accurately muift be undoubt-- edly confidered as an object of much moment, while the know- ledge of the true fenfe and meaning of the Greek authors is held -in eftimation by the world; and that it ever muft be fo, is evident from the confideration that the New Teftament itfelf is written in that language, in the interpretation of which the application of a tenfe may be of confiderable importance. It is hoped, therefore, that any endeavour to elucidate the fubject will meet with indulgence ; and if it be allowed that the preter- perfect applies to an action commenced ata time paft, but ftill prefent in itfelf or in its confequences ; the fecond aorift in its primogenial ufe to the time paft only and indefinitely, 2. e¢. without expreffing the perfection or imperfection of the action ; and the firft aorift to the time paft, exclufively of the prefent, and denoting the perfection of that paft action (as the preter- imperfect does its imperfection), every difficulty is removed, the “ parts all harmonife, and the meaning of the other tenfes being already agreed upon and acknowledged, every one will have its own proper and peculiar primogenial fignification. N. B.. I£ the foregoing application of the word indefinit2 to action, and not to time, fhould feem to any one unnatural, let it be applied to time, and then I fay the preterperfect and firft aorift are definites, becaufe they refpectively define and mark the time of the event to have been /ately, or long fince pait. The tecond zorift is inde- finite, becaufe it does not mark, define, or indicate, whether the time of the event has lapfed /ately, or Jong ago, but leaves it totally uncertain. This mode of referring them to time, though not the one ufually received, is the only one which can con- fiftently juftify us in applying thefe names, according to common ufe.

By a Young Gentleman, an Under-graduate in the Untverfity of Dublin. Communicated by the Reverend JOHN KEARNEY, D.D. S.F.7.C.D. and M.R.LA. Tue divine will being the criterion of moral: reGtitude* to man, his conceptions of the divine nature, upon which depend his * To this it may be objected, that thus the fummit of moral rectitude in the Deity will differ not only in degree, but in very effence, from that which is moral rectitude in imperfe&t agents. I anfwer—No. Perfe€t goodnefs therefore refides in the Deity, becaufe he wills and ever unerringly confults the aggregate of happinefs in his creation, His moral creatures are the lefs imperfeét in goodnefs the more uni- formly they co-operate in promoting the fame end. But it is neceflary that fuch a moral agent as man fhould have fome other immediate ftandard for directing his ations than their tendency to advance the general good of the univerfe; fince his limited faculties muft continually expofe him to erroneous judgments, from the im- poffibility of taking in at one view all the dependencies of caufes and effeéts—all that chain of confequences, which unites the moft diffimilar events and the moft ' diftant periods. Hence the neceflity of feeking the immediate criterion of right and wrong in the will of that Being who cannot err ; and hence too the neceffity that his will fhould be revealed. (F) Read Feb, 135 1790. [ Yr] . his conceptions of the divine will, muft materially influence his moral conduct. And hence we may draw this general conclu- fion, that falfe notions of the Deity muft ever produce more or lefs immorality in our lives. This conclufion we fhall proceed to confirm, by a particular confideration of the moral effects which the popular theology of the heathens was calculated to produce. And if all thofe effe&s were not atually produced, we muft look for their prevention to the operation of other caufes. Nor does it concern our prefent fubjea to confider what were the - opinions of fome more enlightened philofophers about the divine being and attributes ; for the opinions of philofophers have fcarcely any influence upon the practice of the multitude. Anp here poltheifm firft offers itfelf to our view, as the fun- damental dorine of every pagan fyftem ; and polytheifm is a do&rine which ftrikes at the very ground-work of all morality. With the wnzty of God, the immutability and permanence of moral rectitude is immediately conne&ted. Where is the perma- nence or immutability of virtue, if the divine will be not immu- table and permanent? And how can the divine will be immutable or permanent, if there be a plurality of Gods? Admit a plurality of wills, and a contrariety is poffible: but if there be a contrariety, not only the uniformity of virtue is deftroyed, but the fame action may become at once virtuous and vicious, as that aion may to one divinity be agreeable which is difpleafing to another. The impure fenfualift, the violent oppreffor, the fraudulent, the revengeful—will find fome tutelary gods to fanction their moft criminal exceffes—gods to whom their moft criminal exceffes will be but grateful facrifices ; while the man of ftri@eft virtue muft fee [ 5 1] fee himfelf expofed to the refentment of each deified vice. Thus polytheifm, in deftroying the ftability of virtue, deftroys her very effence. Tue fame thing may alfo be inferred by examining one of the fources from which the fyftem ef polytheifm has originated. And here it is neceffary to combat an affertion of Mr. Hume’s, that contains one of thofe fecret attacks on revealed religion, which are no further dangerous than as they come from an infidious foe. In his “ Natural Hiftory of Religion” he afferts and advances fpecious arguments to prove that “ poly- “ theifm was the primary religion of man.” But his affertion and his arguments are founded on this fuppofition, that the Mofaic account of man’s original produdtion is falfe—that the origin of all human fociety is not to be traced back to a fingle pair. The truth of this fuppofition we fhall not try upon the ground of revelation, but examine it merely by the light of reafon. It involves one of thefe two hypothefes—either that there has been a feries of generated beings actually infinite, or that the Deity at firft created a Joctety of men. The former is one of thofe old atheiftical hypothefes, which if at all difficult to be refuted, is only fa on account of its abfurdity and inherent contradictions, _ But the confideration of that is foreign from our prefent pur- pofe. As to the latter hypothefis, if it be received as a maxim that in the inanimate world Nature does nothing in vain, muft it not be equally true that in the animate world the opera- tions of the God of Nature are none of them in vain? And would it not have been operating in vain to have produced a multitude of human beings, by the immediate interpofition of CF 2) his Lead: aI his creatéve power, when the formation of a firft pair would have been fufficient to effe@ the fame end? Secondary caufes, I -allow, and what are called the eftablifhed laws of Nature, are but more remote or more regular exeftions of the divine omnipo- tence. But experience and reafon teftify that the divine omni- potence will thus regularly operate by thofe fecondary caufes, and according to the eftablifhed laws of Nature, except where- thofe regular operations are inadequate. If men were formerly created, who might as well have been produced by geveration, why is not the immediate fiat of the Deity ftill fimilarly inter- pofed? And if not interpofed now, becaufe it need not, why fhould we imagine that it has been at any former period, when its interpofition. was unneceffary ? Thus then the inutility of the fuppofition, and its repugnance to analogy are fufficient to make us reject it, and conclude that the whole human race are defcend- ants of but one man and one woman. Bur there is a ftill ftronger argument in fupport of the fame conclufion. To maintain the contrary hypothefis is to maintain that the power of the Deity in man’s creation was exerted in a manner not only ufelefs, but pofitively hurtful. Human fociety, at the fame time that it affords us means of fupplying our wants with facility, encreafes their number. In the catalogue of our neceflities, by far the greater part will be found to originate in our connection with others. That connection fupplies the neceflities which it creates. But how does it fupply them? By the reciprocation of advantages acquired in the gradual advance- ment of fociety. By the commutation of good offices between the wealthy, the fkilful, the experienced, and the powerful ; which i Pie nbs! which intereft directs, and progreffive civilization enables them to interchange. What then muft be the confequence of a /oczety of created men? of men equally needing affiftance in all things ; and from that very equality of wants, equally incapable of imparting it in any :—the neceflities of each much greater and more numerous than if he were the only individual of his {pecies, and his ability to fupply them infinitely lefs. Is it neceflary to add that the darknefs of the profpect is heightened, when in fuch an affembly of human beings we look in vain for thofe ties of kindred, affinity, gratitude, and previous acquaintance :—for all that now cements the materials of fociety, and fecures its advantages? The confequences that would enfue are fuch as the leaft acute muft perceive, and the leaft candid muft acknowledge to be fatal. ; Reason, therefore, as well: as revelation, authorizes us to affirm that there has been a firft man; and. the immediate inference from this truth direétly contradi€ts Mr. Hume’s affer- tion, that polythei/m made part of man’s primary religious faith. The firft man ftarts into exiftence at the» word of almighty power. What is the firft thought which muft obtrude itfelf on his mind? Is it not this enquiry—‘“ whence am I?” And muft not his unbiaffed, unfophiflicated reafon afcribe fuch a great effect to the operation of a mighty caufe? He views the wonderful fymmetry of his frame, and concludes that the fame caufe is a wife intelligence. He exults in his young exiftence, , and acknowledges that caufe to be as good as he is intelligent and powerful. In himfelf, in his faculties, and his exiftence, he [48 ] he reads—he is forced to read the evident characters of a Being, mighty, bountiful and wife; and this Being is his God. Whe- ther there be other beings equally wife, powerful or good, it concerns not him to enquire. Even if there be, they are no Gods to him. His Creator he naturally regards as his fole divi- nity; and clothes him with thofe attributes alone which awe, gratitude and admiration are calculated to fuggeft. But this fimplicity in the obje& of religious worfhip will naturally ceafe, as the number of worfhippers is augmented. When men are muitiplied on the earth, their corruptions will be multiplied ;—the variety of human_ difpofitions, circumftances and fortunes will be encreafed;—and the image of the Deity, viewed through all thefe mediums, will be tinged with a variety of colours. Different men will form different conceptions of the divine nature; and each different conception will conftitute a diflin@ divinity. And here the vices and evil propenfities of mankind will operate moft powerfully. The god of the volup- tuous, will be a god of fenfuality—the god of the difhoneft, will be a god of fraud—the god of the indolent, will be a god of felfith inativity—of the turbulent, a god of war and violence. Each earthly corruption will by degrees extend its influence to the heavens; and each corrupt deity in return will patronize, extend and perpetuate thofe vices from which he has derived his origin. _I wave thus as briefly as poffible endeavoured to prove that the general tendency of polytheifm is inimical to good morals. I fhould now proceed to examine the various particular evils which ee 9. which it occafions, efpecially that one of diffolving the bond of univerfal benevolence; and the other numerous tenets of pagan theology would next come to be confidered. But thefe open too wide a field to be entered on at prefent. If the fub- jet be refumed at any future period, it will be neceffary to refute fome more opinions, advanced by a writer on whom I have already had occafion to animadvert. a Wun Pre Se ACCOUNT of a SINGULAR CUSTOM a METELIN, with fome CONJECTURES on the ANTIQUITY of is | ORIGIN. By the Right Honourable JAMES, Earl of | CHARLEMONT, Prefident R. I. A. "THOUGH the extreme beauty and amenity of the Grecian Read Dec. iflands, efpecially thofe on the Afiatick fide of the Egean fea, '” ne may render it difficult to make a choice among them, yet, if I were defired to declare a preference, I fhould probably fix on Me- telin, the ancient Lefbos.—This enchanting ifland, proud of the birth of Alceus and of Sappho, ftill retains thofe charms which gave rife and infpiration to their poetry; and though its groves no more refound with their facred ftrains, the caufe that infpired them ftill feems to exift, and love {till lingers in his favourite retreat.— Spirat adhuc Amor Vivuntque commifli Calores fEolize~ Fidibus Puellz ! [A 2] NATURE ae | Nature here reigns triumphant, and by fhewing what fhe can perform alone and unaffifted, teaches us to defpife the weak efforts of her inadequate mimick.—The mountains, whofe rugged tops exhibit a pleafing interfperfion of rocks and of pine groves, have their green fides, for many miles along the coaft, covered with olives, whofe lefs- agreeable verdure is corre@ed, embellifhed, and brightened by a lively mixture of bays and of laurels afpiring to the height of foreft trees, of myrtles, pomegranates, and of arbutes, rich at once in bloffom and in berry, of mulberries grow~ ing wild, and laden with fruit, and of every other tree Of nobleft kind for fight, fmell, tafte! @While the luxuriant vine, climbing wild and unreftrained even to their topmoft branches, adorns and enriches them with its vivid green, and with its cluftering fruit—Winter is here un- known.—The climate forbids it—-The verdure is perpetual, and the frequency of evergreens gives to December the colour of June—The parching heat of fummer is never felt—The thick fhade of trees, and thoufands of cryftal fprings, which every where arife, and form themfelves into unnumbered rivulets, joined to the refrefhing fea breeze, the conftant companion and corrective of noontide heat, qualify the burning air, and render the year a never ending May— — Airs, vernal airs! Breathing the fmell of field and grove, attune The trembling leaves, while univerfal Pan, Knit with the Graces, and the hours in dance, Leads on the eternal {pring !— Paar) ial No wonder then if the inhabitants, the better to enjoy thefe various beauties, fhould conftru@ their houfes in the following peculiar manner :—Each houfe is a fquare tower neatly built of hewn ftone, fo high as to overtop the trees, and to com- mand a view of the fea and neighbouring iflands—The lower ftories are granaries and ftore-houfes, and the habitable apart- ments are all at the top, to which you afcend by a ftone ftair, built, for the moft part, on the outfide and furrounding the tower, fo that from the apartment the trees are overlooked, and the whole country is feen, while the habitations themfelves, which are very numerous, peering above the groves, add life and variety to the enchanting profpect, and give an air of human population to thefe woodlands, which might otherwife be fuppofed the region of Dryads, of Naiads, and of Satyrs. Bur the charms of this delightful fpot have fo far tranfported my imagination that I have almoft forgotten the fubje& of which, in this effay, I meant to treat, and which is no other than a remarkable and fingular cuftom of this ifland, peculiar, I believe, to itfelf, and, as far as I know, never yet detailed by any traveller. Tue women here feem to have arrogated to themfelves the department and privileges of the men.—Contrary to the ufage of all other countries, the eldeft daughter here inherits, and the fons, like daughters every where elfe, are portioned off with {mall dowers, or, which is ftill worfe, turned out, pennylefs, to feek their fortune —If a man has two daughters, the eldeft, at her marriage, is entitled to all her mother’s poffeffions, which are by far ee eam | ak far the greater part of the family eftate, as the mother, keeping up her prerogative, never parts with the power over any portion of what the has brought into the family, until fhe is forced into it by the marriage of her daughter, and the father alfo is compelled to ruin himfeif by adding whatever he may have fcraped together by his indufiry.—The fecond danghter inherits nothing, and is con- demned to perpetual celibacy—She is ftyled a Calogria, which fignifies properly a religious woman or nun, and is in effect menial fervant to her fifter, being employed by her in any office fhe may think fit to impofe, frequently ferving her as waiting maid, as cook, and often in employments {till more degrading.—She wears a habit peculiar to her fituation which fhe can never change, a fort of monaitick drefs, coarfe, and of dark brown. One advantage however fhe enjoys over her fifler, that whereas the elder, before marriage, is never allowed to go abroad, or to fee any man, her neareft relations only excepted, the Calogria, except when em- ployed in domeftick toil, is in this refpe@t at perfe@ liberty — But when the fifter is married the fituation of the poor Calogria becomes defperate indeed, and is rendered ftill more humiliating by the comparifon between her condition and that of her happy miftrefs. The married fifter enjoys every fort of liberty—the whole family fortune is her’s, and fhe fpends it as fhe pleafes— her hufband is her obfequious fervant—her father and mother are dependent upon her—fhe dreffes in the moft magnificent manner, covered all over, according to the fafhion of the ifland, with pearls and with pieces of gold, which are commonly fequins*; thus con- tinually * This fpecies of finery, which prevails through many of the iflands, is never worn in Metelin but when full drefs is deemed neceflary. re ot ae tinually carrying about her the enviable marks of affluence and fuperiority, while the wretched Calogria follows her as a fervant, arrayed in fimple homefpun brown, and without the moft diftant hope of ever changing her condition. Such a difparity may feem intolerable, but * what will not cuftom reconcile? Neither are the misfortunes of the family yet at an end—The father and mother, with what little is left them, contrive by their induftry to accu- mulate a fecond little fortune, and this, if they fhould have a third daughter, they are obliged to give to her upon her marriage, and the fourth, if there fhould be one, becomes her Calogria; and fo on through all the daughters alternately. Whenever the daughter is marriageable fhe can by cuftom compel the father to procure her a hufband, and the mother, fuch is the power of habit, is foolifh enough to join in teazing him into an imme- diate compliance, though its confequences muft be equally fatal and ruinous to both of them. From hence it happens that nothing is more common than to fee the old father and mother reduced to the utmoft indigence, and even begging about the ftreets, while their unnatural daughters are in affluence; and we ourfelves have frequently been fhewn the eldeft daughter parading it through the town in the greateft fplendour, while her mother and fifter followed her as fervants, and made a melancholy part of her attendant train. THE * To what indeed cannot ufage reconcile us? Perhaps if it were the general cuftom of the world that in all families children fhould fhare alike, we fhould be as much furprifed at the fingularity of any particular country where the rights of primogeniture prevailed, as we now are at the Metelinean cuftom, and fhould pity the comparative indigence of the fecond brother as we do the fituation of the miferable Calogria. Le yd Tue fons, as foon as they are of an age to gain a livelihood, are turned out of the family, fometimes with a {mall prefent or portion, but more frequently without any thing to fupport them, and thus reduced, they either endeavour to live by their labour, or, which is more ufual, go on board fome trading veffel as failors or as fervants, remaining abroad till they have got together fome competency, and then return home to marry and to be henpecked. Some few there are who, taking advantage of the Turkith law *, break through this whimfical cuftom, who marry their Calogrias, and retain to themfelves a competent provifion; but thefe are accounted men of a fingular and even criminal difpofition, and are hated and defpifed as conformifts to Turkifh manners, and deferters of their native cuftoms; fo that we may fuppofe they are few indeed who have the boldnefs to depart from the man- ners of their country, to adopt the cuftoms of their detefted mafters, and to brave the contempt, the derifion, and the hatred of their neighbours and fellow-citizens. Or all thefe extraordinary particulars I was informed by the French conful, a man of fenfe and of indifputable veracity, who had refided in this ifland for feveral years, and who folemnly affured me that every circumftance was true; but indeed our own obfervation * It may be afked, how it happens that the Turks do not exert their fovereign and abfolute power entirely to abolifh a cuftom fo contradiétory to the fpirit and practice of their laws? But this is eafily anfwered—In all their conquefts the Turks, either through mercy or through indolence, have left the natives in pofleflion of their -own cuftoms, contenting themfelves with their court of final appeal, and with a fort of cenforial power, which they exercife with much harfhnefs, to their ewn great emolument, and to the oppreffion of their fubjeéts by arbitrary fines. Die] obfervation left us without the leaft room for doubt, and the fingular appearance and deportment of the ladies fully evinced the truth of our friend’s relation. In walking through the town it is eafy to perceive, from the whimfical manners of the female paffengers, that the women, according to the vulgar phrafe, wear the breeches. ‘They frequently ftopped us in the ftreets, examined our drefs, interrogated us with a bold and manly air*, laughed at our foreign garb and appearance, and fhewed fo little attention to that decent modefty, which is, or ought to be, the true charac- teriftick of the fex, that there is every reafon to fuppofe they would, in fpite of their haughtinefs, be the kindeft ladies upon earth, if they were not ftrictly watched by the Turks, who are here very numerous, and would be ready to punifh any tranfgreffion of their ungallant laws with arbitrary fines. But nature and native manners will often bafle the efforts even of tyranny. In all their cuftoms'thefe manly ladies feem to have changed fexes with the men.—The woman rides afiride—the man fits fideways upon the horfe—Nay I have been affured that the hufband’s diftinguifhing appellation is his wife’s family name—The women have town and country houfes, in the management of which the: hufband never dares interfere.—Their gardens, their fervants, are all their own; and the hufband, from every circumftance of his behaviour, appears to be no other than his wife’s firft domeftick, perpetually bound to her fervice, and flave to her caprice. Hence it is that, a tradition obtains in the country, that this ifland was [B] ; - formerly * In the nineteenth Epiftle of the firft book, Horace applies an epithet to Sappho which might with great aptnefs be given to her prefent countrywomen ; «© Temperat Archilochi Mufam pede mafcula Sappho.” [ wi] formerly inhabited by Amazons, a tradition however founded upon no ancient hiftory that I know of. Sappho indeed, the moft re- nowned female that this ifland has ever produced, is faid to have had manly inclinations, in which, as Lucian informs us, fhe did but conform with the fingular manners of her country- women; but I do not find that the mode in which fhe chofe to fhew thefe inclinations is imitated by the prefent female inhabi- tants, who feem perfectly content with the dear prerogative of abfolute fway, without endeavouring in any other particular to change the courfe of nature; yet will this circumftance ferve to fhew that the women of Lefbos had always fomething peculiar, and even peculiarly mafculine, in their manners and-propentfities. But be this as it may, it is certain that no country whatfoever — can afford a more perfect idea of an Amazonian commonwealth, or better ferve to render probable thofe ancient relations which our manners would induce us to efteem incredible, than this ifland of Metelin. Thefe lordly ladies are, for the moft part, very handfome in fpite of their drefs, which is fingular and difad- vantageous. Down to the girdle, which, as in the old Grecian garb, is raifed far above what we ufually call the waift, they wear nothing but a fhift of thin and tranfparent gauze, red, green or brown, through which every thing is vifible, their breafts only excepted, which they cover with a fort of handkerchief; and this, as we were informed, the Turks have obliged them to wear, while they look upon it as an incumbrance, and as no incon- fiderable portion of Turkifh tyranny. Long fleeves of the fame thin material perfe@tly fhew their arms even to the fhoulder. Their principal ornaments are chains of pearl, to which they hang fmall pieces of gold coin. Their eyes are large and fine, and [ i ] and the nofe, which we term Grecian, ufually prevails among them, as it does indeed among the women of all thefe iflands. Their complexions are naturally fine, but they fpoil them by paint, of which they make abundant ufe, and they disfigure their pretty faces by fhaving the hinder part of the eyebrow, and re- placing it with a ftrait line of hair, neatly applied with fome fort of gum, the brow being thus continued in a {trait and narrow line till it joins the hair on each fide of their face. They are well made, of the middle fize, and, for the moft part, plump; but they are diftinguifhed by nothing fo much and fo univerfally as by a haughty, difdainful and fupercilious air, with which they feem to look down upon all mankind as creatures of an inferior nature, born for their fervice, and doomed to be their flaves ; neither does this peculiarity of countenance in any degree diminith their natural beauty, but rather adds to it that fort of be- witching attraGtion, which the French call pzguaat. Tue peculiar fingularity of the cuftom above-mentioned induced me carefully to examine whether any fimilar ufage had any where exifted in ancient times, and, after much fearch, I at length found in Herodotus an account of a cuftom among the Lycians, which bears a ftriking refemblance to this of Mételin, and is, I believe, the only inftance in all antiquity* at all refembling * The only inflance in all antiquity.] 1 have faid in the text that I knew of no inftance in ancient manners refembling the cuftom of the Metelineans, that of the Lycians only excepted. We know however that the Egyptian laws, though there be nothing in them which can induce us to fappofe that any fimilar ufage exifted in Egypt, gave to the women of that extraordinary country certain peculiar and fingular privileges. Diodorus Siculus, Lib. 1. p. 31, after [B 2] having be refembling the peculiar privileges of the ladies of that ifland.—~ “The Lycians, fays he, lib. 1. p. 82, make ufe of the Cretan “ and having informed us that in Egypt brothers were permitted to intermarry with their fifters, in imitation of Ifis whofe marriage with her brother Ofiris had been productive of fuch fignal advantage, &c, proceeds thus—aAiz ds riwlas ras allie, * For thefe reafons,”.(that.is to fay from the veneration of the Egyptians for — Ifis, and from their fenfe of the benefits which ‘had accrued from her excellent ndminiftration after the death of her hufband) §* It has become a cuftom that «© more power and honour fhould be allotted to the queen than to the king, « and that among private people in their matrimonial contraéts, command is “* given to the wife over the hufband, the hyfbands therein promifing to obey “ their wives in all things,” Herodotus alfo, in his enumeration of the many cuftoms in which the Egyp- tians differ from the reft of mankind, mentions fome particulars refpe€ting their -women which feem to) indicate a marked fuperiority in that fex over the other. Among the Egyptians, fays he, Lib, ii, p. 119, the women tranfaét matters of trade and retailing, but the men, remaining in their houfes, weave. And, after fome other whimfical and ridiculous ufages, he adds in the next page that there is no obligation on fons to provide for their parents if they fhould be unwilling, but that, even though againft their will, daughters are obliged to make fuch provifion. Which laft circumftance feems to imply fome peculiar advantages in the women refpedting their patrimony, as it would feem unreafonable that the weaker fex fhould be particularly burthened ynlefs the laws had furnithed them with fufficient ability. This however is merely conjecture, and the Lycian cuftom ftill remains the only inftance in point. And indeed, notwithftanding the authorities above cited, there is, in my opinion, much reafon to doubt that the women in Egypt in reality pofleffed any confiderable degree of fuperiority. In every country where a plu- “rality of:wives is allowed, the fair fex mult always be more or Icfs degraded, and that: Polygamy was permitted among the Egyptians we know from Diodorus Siculus, who tells us, Lib. 1..p. o1, that in Egypt the priefts were confined to one wife, but that all others, might marry as many as they pleafed,—- Tapovos o% map Alyuntiors oF pay Wepre pce, rv 0 wArwy boas av exasog mpoonla—A cuftom which appears to me wholly inconfiftent with the law enforcing obedience in ; hufbands, a ee ee heat J * and Carian laws; one cuftom however they have peculiar to « themfelves, and in which they agree with no other race of * men. They call themfelves by the names of their mothers and * not of their fathers. If any one fhould afk his neighbour who “ he is, he defcribes himfelf by his mother, and recites his ma- “ ternal genealogy ; and, if a gentlewoman fhould marry a flave, “ the children by that marriage fhall be accounted noble ; but, if “ a citizen, or even the firft among them, fhould take to wife a foreign woman, or a concubine, the children by that marriage * are degraded or ignoble—Nopoim: de re wev Kpryfinoirs, to de Kecpsoure © Xpeovjas, &c.” * Plutarch alfo makes mention of this ufage in his hhufbands, fince the fituation of the man, who had married many wives, and was bound to obey them all, is too whimfical ever to have exifted in any country whatfoever. We mutt therefore fuppofe that this law, which had been origi- nally enacted in honour of Ifis, and in favour of the fex to which fhe be- jonged, had, through lapfe of time, and the contradi€tory mamners of the people, become obfolete and inoperative. Vide Sophocles. Ogedip. Col, page 282 Edit. Stephani, with the note by Camerarius, page 191. There is likewife fome reafon to fuppofe that in Attica, before Cecrops, as the beft means of civilizing that hitherto favage country, had introduced the practice of marriage, the women enjoyed the privilege of voting in the public aflemblies, and even that children were named after their mothers. While the connexion between the fexes was cafual and unreftrained, who the real father was could fcarcely be known with any degree of certainty, and the child therefore took the name of the only parent that could be afcertained., See for this, and for much other curious information refpeCting the privileges of women in various ages and countries, Millars diftin€tion of ranks in fociety, page 32 to page 37- * Vide Plutarch, as quoted in the text, for feveral fabulous accounts of the ftery of Bellerophon, one of which contains a circumftance fomething to our purpofe [hose J his Treatife upon the Virtues of Women.—Tom. ii, p. 248.—Edit.

In purpofe, viz.: That this hero not only freed the Lycians from an invafion of pyrates, but from the Amazons alfo, whom he drove out of their country. So that there may be fome reafon to fuppofe that the Lycian women, by an inter- courfe with the Amazons, who had,. it fhould feem, dwelt among them, were already previoufly prepared for the introduction of thofe cuftoms, which were finally eftablifhed in confequence of their patriotick merit in deprecating the wrath of Bellerophon, and in averting its fatal confequences. foags | In confequence of the ftriking refemblance between this cuftom and that of Metelin, I ufed my beft endeavours to find out fome authority for the peopling this ifland from Lycia, but could trace no fuch origin. The inhabitants of Lefbos were Aolians, and, let us go back ever fo far, we can only find that the ifland had, in times of the higheft antiquity, been colonized by the Pelafgi. However, if we may fuppofe that this ufage fubfifted among the Lycians fo late as in the times of Nicolaus Damaf- cenus and of Plutarch, that is to fay in the reign of Auguftus, and in thofe of Trajan and of Adrian; and, fince from the filence of ancient writers upon this point, and more efpecially from the negative authority of Herodotus, who exprefsly fays that in this inftance the Lyciams agree with no other race of men, we have fome reafon to believe that it may not be of very ancient ftanding in Lefbos, there is no impoffibility in the fuppofition that in the latter ages fome colony may have pafled over from Lycia into Metelin, and may have there eftablifhed this extraordinary cuftom, a fa& of which the deficiency of hiftorians in thofe times may have left us ignorant. Wirt this flimfy conje@ure I was compelled. to content myfelf, and, though by no means fatisfied, had well nigh given up the point, when, happening one day to turn over Diodorus Siculus for fome other purpofe, I fortunately, but accidentally, met with a paflage which had hitherto efcaped all my painful refearches, and which I read with a degree of pleafure only to be conceived by my antiquarian brethren. It feems that thofe Pelafgi, who under their leader Xanthus, the fon of Triopas king of Argos, firft [ 36 ] firft inhabited ~Lefbos, had, before their fettling in that ifland,, dwelt for fome time in a certain part of Lycia which they had conquered, and may of confequence be fuppofed to have brought from thence the ufage in queftion. The paffage is as follows, Tom. t. Lib. v. page 396. Edit Weffellingii. eps Te Nese voy Aeyew eminespnooper. Tourn yap Ty vyrov TO Tahouov wunnari mrcio yey, ToAAwY pclavectarewv ev coin yevonevav.

Ler us now endeavour to: {peak of Lefbos——Many nations anciently. inhabited this ifland, repeated emigrations having been made into it. When yet a defart the Pelafgi firft occupied it; and in this manner—Xanthus the fon of Triopas, ruling over the Pelafgi who came from Argos, inhabited a certain part of Lycia which he had fubdued, and governed the Pelafgi who had gone thither with him. Afterwards paffing into Lefbos, then a defart, he divided the country among his people, and he named the ifland from its inhabitants Pelafgia, which had before been: ealled Iffa.. But after feven ages the deluge: of Deucalion hap-- pening, &c. &c. i Ne biay He then proceeds to relate how (many of thefe firft inhabitants having perifhed) the ifland was in a courfe of ages peopled by various colonies from different nations. Tuus have we traced a poflible, though very remote fource of the ufage in queftion. The diftance of time, to be fure, is great; for Triopas, according to Blair, was king of Argos in the year 1553 before Chrift, or, according to Diodorus, ftill much earlier, as that hiftorian places the colonizing Lefbos by the Pelafgi under the fon of this prince feven ages previous to the flood of Deucalion, which event took place in the year 1503 before the Chriftian Era. But in the eye and eftimation of a true antiquarian what are thirty or forty centuries? To fpeak however ferioufly, though I be far from having the bold- nefs to defire that implicit credit fhould be given to an origin fo remote as almoft to tranfgrefs the bounds of hiftory, confcious as I am that fuch a fpeculation may be liable to ridicule, and aware of fome objections not eafy to be anfwered, the coincidence will, I believe, notwithftanding, be allowed to be curious and very remarkable. The well-known pertinacious adherence to ancient manners among the eaftern nations may in fome meafure excufe our credulity, and we may ftill add to our authority by fuppofing that this fame Xanthus may probably have given his name to the Lycian city of that denomination, and confequently muft have inhabited that very part of Lycia where, according to Plutarch, the cuftom is fuppofed more immediately to have flourifhed. It would indeed be whimfically curious if we could allow ourfelves to imagine that a fingular cuftom at this day fubfifling could be traced back to an origin fo very remote, [C] and bate od and fhould have taken its rife in a period when the ‘world was yet in its infancy, or that ‘the relations of Diodorus and of Plutarch, which, confidering the times of which they treat, might, with much appearance of reafon, be deemed fabulous, fhould be corroborated, and, as it were, authenticated by a cuftom at this day fubfifting. I sHovip not perlaps have hazarded giving to the public a relation of fo extraordinary a nature, had the facts, as I had fup- pofed when upon the fpot my notes were taken, refted folely upon my teftimony, but, having lately found with much fatif- faGtion that this fingular cuftom is mentioned, though by no means detailed either in its circumftances or moral confequences, in the Letters concerning Greece, written from Conftantinople by Monfieur de Guys, under the title of “ Voyage Litteraire.” Iam the rather emboldened to venture the above detail of an ufage, the exiftence of which has been thus authenticated, though, from want of fufficient information, it has been flightly and fuperficially treated ; neither can I help exprefling my furprife that a matter fo fingular in the hiftory of mankind fhould have been deficient in point of evidence, or fhould have efcaped the notice of fuch travellers as have fpent much time in thefe iflands, and confe- quently have had every opportunity of accurate inveftigation— Monf. de Guys, in the prefent inftance, did not moft certainly poffefs this advantage, not having, as he tells us, been able to verify the fact: “ Comme dans le cours de fes voyages il n’a fait * qu’ aborder a cette ifle, et n’y ayant pas fait de Sejour.” He had however been informed that in the ifle of Metelin, “ Toutes “ les proprietés et tous les immeubles appartiennent aux filles, et a “Ja —————— rr ae [ 19 J « Ja fille aineé, ce qui emporte Vexhereditation des Gargons.’— I was affured, continues he, by the firft inhabitant whom I gueftioned, that the fact was literally true, that the cuftom was of very ancient date, and that the males had willingly confented, « A tout ceder a leurs foeurs pour leur procurer de meilleurs eta- n « bliffements.. Ils_pourroit, ajoutoit il, sils vouloient, reclamer « Ja Loiturque, qui admet tous les Enfans au Partage des Biens paternels ou. maternels, mais ceux gui voudroient ainfi fe fouf- traire a la Loi du Pais, feroient defhonorés.” —/gvage Litteraire, Tom. i. p. 398. 2S 5 ns in Monf. de Guys next. proceeds to account for, the rife of the euftom, which he fuppofes to have been very ancient in the ifland ; and. this he does in a manner which appears to. me rather unfatisfaCtory, by, a detail, extracted for the moft part from Diodo- rus Siculus, lib,, xii. of , the bloody quarrels, between the Lefbians and the Athenians, and of the many revolutions to which the ifland had ‘been fubje@, concluding with the following remark :—‘ Or « comme je vois dans toutes ces revolutions les femmes epargneés, « ne fuxent elles pas d’intelligence ayec les nouveaux habitants “ pour affurer dans leur familles la propriété des pofleffions, ‘et fe “ les jattribuer,.4 elles feules ? Defquelles eurent eté .reconnues « maitreffes des Biens qui leur etoient auparavant communs avec « leurs maris, l'ufage en fit peutetre enfuite une loi qui ne « peut etre plus favorable pour elles. Wuegre Monf.du Guys has found, that in all thefe revolutions the women were fpared, | know not, but, be this ‘as it may, there are unfortunately few countries in Greece, or indeed I fear in [C 2] the [ 20 |] . the world, where the women might not have had, at fome : period or other, a fimilar opportunity for encroachment ; neither does it appear very probable that they fhould have made fuch extraordinary terms with the conquering Athenians, fince we- know, from the experience of all ages, that conquerors are not apt to accept of terms from the women of the vanquifhed. It is indeed difficult to believe that the ladies would have hazarded, or even thought on, fo ftrange a propofition, unlefs we fhould fuppofe fome pre-exifling peculiarity in their manners, and in the ancient cuftoms of their country, which might induce them to propofe fuch wonderful terms, and encourage them with the hope that, if obtained, their men would comply; and this fup- pofition will bring us back to the early eftablifhment of the Lycian ufage, which, having poffibly grown into difufe in a ; long courfe of ages, may have been renewed upon this occafion, when the ladies found themfelves ftrong enough, with the affiftance of the conquerors, to reaffume that ancient fuperiority, which, though for a time they might have been compelled to yield, it is highly probable they would never forget; and indeed there is fome reafon to fuppofe, from the filence of hiftorians, that the cuftom may not have been always permanent in the ifland, but may have occafionally ceafed, and been renewed from time to time. OBSERVATIONS on th DESCRIPTION of the THEATRE of SAGUNTUM, as given by EMANUEL MARTI, Dean of Alicant, in a Letter addreffed to D. ANTONIO FELIX ZONDADARIO.

It is defended from the fouth and weftern winds by the intervention of the mountain which encircles it; fo that it only admits the falutary north and eaft, fecured from the other noxious blafts. Such is the advice of Vitruvius in the conftruction of theatres. , “ Tue circuit of the femicircle is five hundred and fixty-four of our palms*, each palm being three-fourths of a Roman foot: the diameter, by a line drawn from each angle, is. three hundred and thirty palms: the height of the theatre, from the orcheftra to the fumma cavea, one hundred and_ thirty-three palms and an half, but to the top of the remaining wall one hundred and forty-four palms and an half: the diameter of the orcheftra is ninety-fix palms; from which place we will begin the defcription as frem the centre. In that moft diftin- gifhed place fat the praetor in the, fuggeftum, the remains of « which Y; * The Valencian palm is nine inches; and thirty-fix Valencian inches are equal io thirty-three inches Englifh. Tape sid at s eee eee Eee + 7 ae . ° eee ea which appear in the middle of the orcheftra at the podium; then the veftals, priefts, ambaffadors, fenators. That the view of the ftage (pulpitum) might not be intercepted, it was inge- nioufly contrived that the pavement of the orcheftra fhould rife gently from the fuggeftum to the loweft bench of the knights, the pavement being lowered and cut circularly in the nature of a belt for placing and fixing the feats, leaving a little higher {pace between the rows of feats to facilitate the going out and coming in. From the level of the orcheftra the feats of the knights begin, being fourteen rows as appropriated to them by the Rofcian and Julian laws of the theatre. At the feventh tow two vomitoria afford entrances, which row is therefore broader than the others, that the knights, who were nume- rous, might not be preffed by the narrownefs of the place, but difperfe themfelves with eafe into their feats. This thea- tre is founded on a very hard rock, whofe refiftance defeated the fkill and labour of the workmen: on that account the knights had only two doors, which not being fufficient, ftair cafes were added, one on each fide, in an open place: below, whofe loweft fteps go under an arch in the very profcenium. The upper bench of the equeftrian order is encompatffed by a precinGtio; by which name the ancients called a bench twice as high and broad as the others, which as it were girded and em- braced the reft. They were inferted in this manner, that the difference of orders, namely, fenatorial, equefirian and plebeian, might be apparent, and that there might be no intercourfe be-. tween them. Twelve benches of the people follow on a higher and more remote fituation, where plebeians fat; this they call the a 5 ai ee the fumma cavea. To thefe places they poured in by many paflages, to which accefs was had through interior vaults ‘And corridors. There was alfo an upper portico, which anfwered two purpofes: the one, that the people might have a place of fhelter in cafe any fudden ftorm or fhower fhould come on during the plays; the other, that the theatre below might be preferved from the rain and filth. This portico has eight doors before, and as many behind, and oppofite. Seven ftair cafes afford an afcent to thefe doors, beginning at the loweft bench of the knights next to the orcheftra. The ftair cafes however are not interrupted‘and winding as in many amphitheatres, but in a ftrait and continued courfe; fo that they make long divi- fions like wedges, and form an agreeable coup d’ceil to the fpeators from top to bottom. Thefe ftairs were the ways between the cunei for afcending, for as the benches were higher than a common ftep, and could not be eafily climbed, the ftairs were ingenioufly contrived fo as to make a third ftep between every ‘two benches, except where the ‘precinétios intervened, and in theft there are four. The breadth of thefe ftairs is three palms and ‘a half, and the heighth one palm a digit and a half; which dimenfion is doubled by that of the feats. Thefe flairs were contrived for this purpofe, that the people in the cunei might eafily get out whichever way they fhould turn, and likewife that thofe who could not get feats might fee the performance flanding. There is a difference between the inter- nal and external doors; thofe within are fquare and broad, and thofe without arched and narrower. The upper portico is twelve palms and three-fourths in height, and fifteen and a quarter > “ broad, y 5 et 9 een ee eee [.aa5 ‘al ‘ broad, that.the people coming in or going out fhould not fuffer from, the narrownefs, of the portico. This portico does not ex- tend to the angles of the theatre, but ftops,and is cut off: oa each fide, by an interval of thirty-five palms, which was filled ‘ by four benches differing from the cavea below only in this, that the upper bench. of the people was. broader, than the reit, and formed a. fort of fmall precin@io or area; diftinguifhing the upper from the lower order. Certain concealed flairs lead from thofe benches to the prifons (of which one ftill remains), where yokes, or iron rings are fixed to the walls for binding the _malefadtors. I muft obferve ftill farther that the portico is broken in the, middle, an interval being left between of twenty- two palms, on each fide of which there are four fteps, extend- ing feven palms and a half. Some faint remains of a bafe give room fo conjecture that a flatue was-placed in the middle of thefe, which the uniformity and finifhing of the building re- quired to mark the centre of the femicircle. The fides of the baie are fix palms and three-fourths broad, In the highefi bench of. the cavea, on each angle of the theatre, appear fix arched ¢ windows, three on each fide: Over,-ithe portico there are four benches, the upper bench being broader than any even of the precinctios: certain fmall flairs furnifh an afcent from the four feats above mentioned to thefe upper benches, as well on each fide of the theatre as in the middle. The entrance to thefe feats is by detached ftairs projeCling behind the portico and con- tiguous to the mountain, leading to arched door-ways in the higheft part of the wall, of which only one remains. In the back part of this wall there are likewife quadrangular ftones, ten [D] “ palms \y [ 26 ] palms and a half diftant from one another, of a fquare figure, * two palms and a half each way; for the explanation of which it is neceffary that you fhould know that it was formerly the cuftom to firetch fails over the theatres, as well as the amphi- theatres, to keep off the heat and fun. Thefe fails were tied to upright poles, ropes being ftretched acrofs to prevent their floating about by their loofenefs; the poles were pafled through circular holes in the upper ftones, and received in thefe pro- jeCting Nones, in the middle of which little grooves are hollowed to prevent the poles from flipping and fhaking. The wall that rofe above thefe benches is deftroyed by the ravages of time, and in the remains there is neither coping or cornice. The fteps of the feats are higher than prefcribed by the rules of architecture, for they are two palms one fourth, far different from what Vitruvius direéts: the breadth correfponds exadtly to his rules, being three palms one-fourth. You may be fur- prized at fuch a breadth, but nothing could be of greater con- venience to the audience, that thofe who fat in the upper bench might not fuffer from the contra€tion of their legs, or hurt thofe below by kicking them; perhaps alfo there might be room to pafs behind if any went out or came in late. The heighth of the precin@io is double, according to the rule, being four palms three-fourths; and alfo the breadth, being fix palms one-fourth. An entry is open to thefe feats by many doors, which are vulgarly called vomitoria, from which the people entering in crouds proceed in to the feats as if vomited forth. Two porticos lead to thefe approaches: the upper one through the open air, as explained before, the other below, creeping through “ the Os o ra “ ro a c « c Fags J the bowels of the mountain like a burrow, and receiving the: light from the doors. Perhaps you would rather call this a vault than a portico: it is nine palms three-fourths in breadth, and twelve in heighth. At each extremity of the theatre there are many remains of buildings that have yielded to the in- juries of time, but which fufficiently teftify the greatnefs of the work; in thefe various vaults are feen, part in ruins, part entire, which fuftained the covering of the fcena. “ Tue various benches of this theatre (allowing a palm and a half to each perfon, and omitting the ftairs for afcending and defcending) contained feven thoufand four hundred and twenty- fix perfons: befides which we muft add thofe who fat in the upper bench above the portico, and brought feats, or leaned againft the wall, amounting, as I judge, to about one thoufand, and thofe of the more diftinguifhed order in the orcheftra, the compafs of which feems to allow for fix hundred feats. Thefe altogether make nine thoufand and twenty-fix. “ In the front of the theatre lie the profcenium, pulpitum and fcena. The profcenium is that {pace extended before the fcena, whereon was ereéted the pulpitum on which the actors appeared. _ Notuine remains of our pulpitum except the foundation of ca e s . « . the wall diftant from the orcheftra about twelve palms, which wall, according to-rule, ought to be only five feet or fix palms. two-thirds high, that thofe who were in the orcheftra might fee LD 2] *¢ the [ 28 ] the geflures cf the aGtors: the pulpitum ‘then was lower than’ the fcena, which is obferved in our theatre. That {pace which extended oppofite the theatre, betwéen the two wings, was called the fcena; the length of which ought to be double the diameter of the orcheftra, as dire€ted by the ancients.’ That’ part is almoft defiroyed in our theatre, except ‘the ‘advancing wall which feparated the feena from ‘the pulpitum and ftretched to the angle of the theatre. From: the orcheftra‘to the fcena is twenty-eight palms and an half, of which twelve were allotted to the profeenium, and the reft to ‘the pulpitum the breadth therefore of the latter was fixteen palms and a half, which {pace feems fufficiently convenient” for thé performences. | In’ the middle of this wall, oppofite the centre of the orcheftra, a plain cemicircle appears, from whofe circuit a convex wall was raifed and vaulted in the form of a fhell, called the valve regie from their ornament and extent: each of the doors on eithet fide were of the fame form but lefs, and thefe they called hofpitalia becaufe deftined to the introduétion of “ftrangers on the fcena; fome remains of thefe ‘appear, particularly of that on the left, whofe circle can bé traced. That on the right has perifhed entirely,’except fome figns of the lateral wall at the angle of the entrance.” Sucu is the defcription given of this theatre by a very learned man, who was refident for many years at Valencia, within four leagues of Morviedro, the modern name of Saguntum. THE nN [29 ] Tue Dean feems to have fallen into the common error of thofe who adopt a fyftem. Being perfuaded that this theatre was a Roman work, he previoufly determined what ought to be the dif pofition of every part, as defcribed by Vitruvius; and adapting all his obfervations to thofe rules, he faw nothing but what cor- refponded with his fyfiem. As the plans now fubmitted to the Academy were taken at a time when there was no opportunity of confulting any ancient writer on ‘the fubje@t, and the meafurements made from what was a€tually feen to exift, thefe obfervations are at leaft free from that ‘error. Tuts theatre is fituated on the: north-eaft declination of the hill on which the renowned citadel of Sazuntum is fituated, where “ Eminet excello con/urgens colle Saguntos,’ and within one hundred and twenty yards of the wall. Advantage is taken of the ground for the difpofition of the feats: the feveral approaches from the town and entrances to the feats are contrived with great inge- nuity, and fo difpofed as to afford a convenient admiffion, without incurring great expenfe in levelling and working the rock upon which it is founded *. Ir is built entirely of limeftone in even courfes of from feven to eight inches thick without any mixture of bricks. No. erna- ment * Fundamentorum autem fi in montibus fuerit facilior erit ratio.

As to the ftruéture, it feems in fome meafure to correfpond with the rules laid down by Vitruvius for Roman theatres, as I find that by infcribing the four equilateral triangles* ACB, GHI, MKL, DFE, in a circle whofe diameter FI is equal to the diameter of the orcheftra, in the triangle ACB the fide AB, which is parallel to the fcena, determines the front of it: A line FI drawn through the centre and parallel to AB feparates the pulpitum from the orcheftrat: The points Kt and L determine the entrances 44 to the firft clafs of benches, and the length of the fcena§S MR is double the diameter of the orcheftra, according to * Ipfus autem theatri conformatio fic eft facienda, uti quam magna futura eft peri- metros imi, centro medio collocato, circumagatur linea rotundationis, in eaque qua- tuor fcribantur trigona paribus lateribus, et intervallis, que extremam lineam circina- tionis tangant.

Dean Marti fays the diameter of the orcheflra is ninety-fix palms, or fixty-fix feet Englifh; but in this he muft include the firft bench, the orcheftra being only fifty-eight, and the bench four feet broad: he is miftaken greatly in the meafurement acrofs the whole from angle to angle N O, by him ftated to be three hun- dred and thirty palms, or two hundred and twenty-fix feet and eleven-twelfths Englifh; which fhould have been given as the extent of the fquare part of the building PQ, The diame- ter NO from angle to angle is two hundred and eighty- three feet, and confequently from the conftruction of the theatre the exterior femicircle from N toO, including the platform that communicated to the corridor leading to the benches of the people, was four hundred and fifty-three feet fix inches*, that is, a diameter and a half and twice the fourth part of a diameter of the or- cheftra. Where the dean found a femicircle of five hundred and fixty-four palms, or three hundred and eighty-feven feet and an half Englifh, I cannot conjecture. The height + that he afligns to the fumma cavea is one hundred and thirty-three palms and an half, * Lipfus: Cap. 8 de Amphitheatro.

This varies very confiderably from my} mea- furement, which is only feventy-one feet; but part of the upper wall is deftroyed. I conclude therefore that the dean miftakes when he takes his meafurement from the orcheftra, and that he really took it from the bottom of -the front buildings, to which it anfwers. As to what he afferts of the remains of the fuggeftum in the middle -of the otcheftra, I could not perceive them, but. if there were any they were probably thofe of the éywedy or tribu- nal*, : He is evidently miftaken when he afferts that there:are*four- teen benches appropriated to the knights; this is a ftriking circum- ftance in which the conftru@ion of this theatre difagrees with the rules for the Roman theatre. Thefe benches are here divided into two diftin@ claffes: in the firft divifion there are feven benches, to which an entrance is afforded immediately in ftrait corridors from the eaft and weft fides, a2, a2. The upper bench of thefe, as the dean obferves, is wider than the reft, being four y feet * Ey OPNNTT pe Kab n Oupirn, ete Bru th, cuca es TE Busos. Pollux, Lib. 4. Cap. 19- Sueton. in Claudio.

Tuere is one window on each fide, 6, 4, next the fcena, which gives light to rooms under the fumma cavea, and two doors, g, 4, which lead to thefe and other detached rooms. Here it may be proper to obferve the contrivance of the archite@ in managing the feveral approaches on the fide of the hill, which are fupported by walls and entrances made to the theatre, to communicate in the moft convenient manner poffiblet. Thefe entrances are uni- formily contrived to give admiffion on the level of the uppermoft bench of the feveral claffes, with ftairs defcending to the precin¢tio, which feparates each clafs. from that immediately adjoining and below: a convincing proof that the two firft claffes of benches were not intended for one and the fame order of citizens. The principal entrances, 241, a1, are by arches of thirty feet high and anfwering the vertices, FI, of two of the equilateral triangles, whofe bafes are at right angles to the fcena. This feems to be the approach to the platform K HCED, of four feet broad and one foot high, next and adjoining the orcheftra. About thirty feet diftant from this principal entrance and higher up the hill two other arches, 22, 22, about five feet lower than the others, lead [E 2] “by * See Plate I. in which the ftairs are marked) by dotted lines to anfwer to: the feveral vomitoria. ; ‘+ Aditus complures et, fpatiofos oportet difponere, nec conjunctos fuperiores inferioribus, fed ex omnibus locis perpetuos, et direétos fine inverfuris faciendos, uti cum populus dimittitur de fpe€taculis, ne comprimatur, fed habeatex omnibus locis exitus feparatos fine impeditione.

THESE two main entrances on each fide have communications with each other of ten feet wide, at thirty-eight feet fix inches diftant from the outfide of the theatre. On the eaft fide there is a double communication between thefe corridors, which appears to have been occafioned by the form of the hill. The approach to the upper arch being eafier was probably more frequented, and thofe crofs corridors gave admiffion, the firft to the apartments be- hind the ena, the fecond to the orcheftra. "The entrance to the fecond clafs of benches on the weft fide is by a corridor of fix feet, 23, at right angles to and communicating from the principal corridors below, aud leading to five doors or vomitoria, cI, ¢ 2, ¢3,¢4,¢5. The declivity of the hill on the eaft fide prevents a fimilar communication to the feveral doors or vomitoria on that fide, and there the corridor, a 4, leads to a flight of ftairs coming out like cellar {teps from under the third bench of the next clafs of benches above atc 6. But there are two entrances from without higher up the hill, @ 5, @6, communicating to the corri- dor, 4 3, a6, and communicating to the °firft. five vomitoria, cw, CzC: Tue uppermoft bench of this:clafs is four feet wide, and im- mediately above this the principal precinétio is four feet fix inches in breadth and four feet in height, feparating the benches of the main body of the citizens, to which a regular approach is afforded by 34 by a portico of ten feet fix inches in width, communicating, as the Dean obferves, by doors, 27, 47, from without, and oppofite to thofe which give admiffion to the upper benches of this clafs. There is no entrance to this upper clafs of feats but by the prin- cipal and upper portico, or rather corridor, except one, f, which communicates by a narrow paflage, a 8, from the weft fide under the corridor: all the reft are by regular doors from the corridor. This entrance feems to be made for the convenience of the people coming from the weftward, as the declivity of the hill pre- vented a communication with this corridor. It is brought under the corridor, and communicates at the fixth bench from the top at f This corridor ferves no other purpofe but for entrance being only ten feet fix inches wide, and has eight doors, thofe on each fide the centre being clofe to the wall of the middle loggia. It is nine feet three inches in heighth, upon the top of which is placed the fumma cavea, confifting of four benches: the two centre ones of the fame width of thofe below, the loweft four feet, and the uppermoft contiguous to the wall five feet fix inches; to which uppermoft bench fmall ftairs e, e, e, communicate from the outfide of the theatre. So that it is evident that each feparate order of citi- zens gained admiffion at the top of thofe benches appropriated to their order, and that, befides the places adjoining the orcheftra, there were four feparate claffes of benches, being one more than appears to have been ufual in the conftru€tion of Roman theatres, which confifted only of ima, media, and fumma cavea*. ANOTHER * The divifion of this theatre feems to correfpond to the Beayrixer and EQnCixor of the Greeks. See Pollux. bivee :d AnoTHER circumftance diftinguifhing this from the Roman theatres is that the orcheftra is not divided in cunei, but fhews two rows of places in its circumference of extraordinary breadth, and which being only one foot in heighth and too low for fitting were probably appropriated to the chairs of the magiftrates and other diftinguifhed perfons. As a proof of the juftnefs of the Dean’s remark on the pro- jeGing ftones at the top of the theatre, there is a hole at three feet fix inches from the centre and nearer the fcena, of fix inches {quare and four feet fix inches in depth, which appears as if intended for the purpofe of fixing a pole to fupport the awning. What he fays of a prifon feems to arife from cavities, mm, m, 1m the building, which were neceffary to fave expenfe: and as to his concealed ftairs, he miftakes the vomitorium on the eaft fide to the fecond clafs of benches for thefe ftairs. The loggias in the centre and the fides do not extend fe far as laid down by him: the breadth of that in the centre is only fixteen feet; a groove of about three inches broad is cut in the ftone in front of this, with a fmall one on each fide. Similar loggias appear in the theatre of Hercula- neum, but I could not afcertain the entrances of either, poffibly they might be on the fides communicating from the fumma cavea. Tue conftruction and fituation of this theatre bear a ftriking refemblance to that of Athens, which Paufanias tells us commu- nicated to the Acropolis by a cave. That citadel towered upon a hill extended nearly eaft and weft like this of Saguntum: to the north, [49,4 north, with a little inclination to the eaft, was fituated the theatre of Bacchus, which appears by the meafurement of Le Roi to have been nearly of the fame dimenfions with this: and Monfieur de Choifeuil, in the Voyage Pittorefque de la Grece, informs us that the theatre at Sparta was fituated in the fame manner, and almoft all the theatres that he met with in Greece. Tue divifion of the benches in this theatre, totally different from the theatres of Pompey, Marcellus and Pola, correfponds with that of the Grecians, as well as with thofe of Taormina and Syracufe: and though the original conftru€tion of it, which is evidently upon the plan laid down by Vitruvius as chara@teriftical of the Roman theatres, (that is, of being determined by the dif- pofition of four equilateral triangles, and differing from the Grecian theatres, determined, according to him, by three f{quares infcribed in a circle whofe diameter is equal to that of the orcheftra) would feem to refer the building of this theatre of Sa- guntum to the era of the Roman fettlements in Spain; yet there are not wanting reafons for doubting the validity of this argu- ment, fince the plans that have been lately publifhed of the theatres in Sicily convince us that this rule was not peculiar to the Roman theatres. It may, therefore, be thought perhaps of a date much earlier, and of Grecian ftru€ture, as it cannot well be fuppofed that a Grecian colony, powerful as the Saguntines, who refifted the whole ftrength of the Carthaginians during a fiege of eight months, would be lefs inclined to public amufements, and lefs fplendid in their preparations for them, than the numberlefs- colonies [ 40 ] colonies fettled in Sicily, in each of which a theatre feems to have been a neceffary building, not only for their amufements but for every purpofe of the public affemblics of the people.

Thus circumftanced, the fubje& may be thought not altogether unworthy of farther “confideration, when we {hall find perhaps neither of the above affertions perfectly juft. Protemy compofed ‘his fyftem of geography from the MSS. in the Alexandrian library, and principally from the works of Marinus Tyrius, a navigator under the, Romans, who, we may reafonably prefume, collected every difcovery made by the Romans on this fubje@t, efpecially that relative to the Britifh iflands, [G 2] from Read Jan. 16, 1790. [ 52 ] from the accounts taken about the year 79 by order of Agri- cola, who was the firft that dire@ted a Roman fleet under the command of Demetrius to circumnavigate Great Britain and Ireland. (Eufeb. Prep. Ev. L v. c. 17.) From the difcoveries made by this fleet, and the information obtained from mer- chants trading to thefe iflands, the Romans obtained the firft circumftantial account of Ireland. But from thefe accounts there is reafon to imagine, that thefe merchants knew no more of its internal ftate, than thofe to whom Ceefar applied, did of that of Britain. (Comment. 24. 19.) They had indeed traded to the coafts, landed their wares, and perhaps enquired and obtained the name of the diftri@ or people with whom they traded; but they made no further difcoveries, the internal parts. of the country were in a manner unknown to them. Tus names therefore mentioned by Ptolemy, relate only to a few maritime diftri@s. But thefe diftri@s, both in refpe@t to their names and fituation, are far more accurately defcribed than is generally imagined. The latitudes and longitudes are indeed wrong, probably arifing from the inaccurate inftruments in thofe times ufed to take obfervations. The longitude is taken from Ferro, one of the Canary Iflands. But we will pafs by the geographical and aftronomical errors of our author and proceed to confider the topographical part of his work, which commences thus: IOYEPNIAE NHZOY BPETANNIKHE @EEIE. IRELAND thus denominated by Ptolemy Iovepue, and by Strabo Iepe, is perfe@ly agreeable to the indigenous name given to it by the natives from the remoteft periods, who always diftinguifhed their i ee their country by the denomination of Ezrean, Erin or Ibh Etrean, pronounced like Ow Erin or You Erin, whence the Greeks could exprefs the found no otherwife in their language than Iepve or Tovep@, nor the Romans than by Hibernia. Even the Welfh call it Yverdon, and alfo the Anglo-Saxons, according to Alfred in Orforius, Jghernia. The Danes were the firft who gave this ifland the appellation of Irdand or Traland, or the land of the Jra; but which like the others is derived. from the indigenous Tbh Erin. Hence we may obferve the care the ancients took to obtain the true names of the countries they difcovered ; and Ptolemy, in the method he has taken in defcribing the coaft, feems to have followed the real tra€t of the Roman fleet, which having circumnavigated the northern coafts of Britain, fell in with the weftern ifles, which are thus defcribed, “ Demetrius ait, infularum “ qua Britaniz adjacent, effe multas defertas—quam pauci ad- “ modum incolerent, fed qui Britannis facri omnes erant, et ab “ omni direptione injuriaque tuti,” (Eufeb. Prep. Ev. |. 5. c. 175 et Plutarch de Oracul. defe@t. T. 2. p. 419.) From thence failing for Ireland, the firft land they could make would be the northern parts of the county of Donegal about the north cape, called by Ptolemy Bopesov axpoy popes, whence they proceeded eaftward, till they came to Fair Head in the county of Antrim, the utmoft ftretch of the northern coaft eaft, then returned and coafted along the weftern fhores of the ifland, thence along the fouthern, then teturning by the eaftern again to Fair Head, croffed the channel and ran down the weftern coafts of Britain to the fouth, and finifhed their circumnavigation of both the ifles.

By the old © an sae old Irith poets, Keating, and other Irith Hiftorians, they are denominated Zvatha de Danann, Fir Domnann, Fir Galeon, Nemed and Fir Bolga; or rather they were feveral tribes, under thefe names, of the Fir Bolga.

Wherefore the Epdwor of Ptolemy and Ernai of the Irith might be defcendants from the Vaf Ernai and Jra, and who were denominated alfo Nemetbones or Nemedones, from being fettled on that river; and were the Nemed of the Irifh, The Gyllen in general were the Fir Galeon of the Irith, The Dieff Gyllen were the Dubb Gals of the Trifh ; the Fingyllen the Fin Gals of the Irith. The Oefergyllen the Oir Gals and the Weffergyllen the Eir Gals of the Irifh, The Dumna or Danes, were the fir Domnann of the Irifh. (For this com- pare Keating and other Irifh hiftorians with Pom.

There are ftill remaining a rath and an an- cient cemetery, called by the natives Rivligh na Righ. Aowov. From Ptolemy’s tables, this city and Pai@a were not far from each other ; yet Camden will have it to be Downpatrick in the county of Down; whilft Ware very juftly thinks it Dunnamaes in the Queen’s county, the ancient feat of the chieftains of Leix, fituated on an ifolated rock, where {till remains the ruins of a caftle built by Lord Pembroke in 1216.

By Mr. WILLIAM BEAUFORD, 4. B. ‘Tue parifh church of Killoffy, in the barony of Naas and Read Jan. county of Kildare, for the fingular conftru@tion of its fteeple, *? ‘7? merits the attention of the curious in antiquities. The prefent church is modern, but ftands on the foundation of the ancient, which it. equals in every dimenfion, except the height of the roof, which originally was conftructed of ftone, as in the ancient churches of Glendaloch and Cafhel, as is apparent from fome remains of it {till vifible at the tower. The tower which joins the church is round, and founded on a fquare bafe, nearly half of the prefent height, each fide terminating in a pediment or triangle of equal altitude, from one of which poeceded the ftone roof of the old church. (Ka) Turs EE ieee] Tuts is probably an unique, being the only one of the kind, I believe, yet difcovered in this kingdom, if not in the Britifh ifles. The tower of the ivy church “at Glendaloch, and the old church of Little Saxum_ near Bury in England, are thofe which have the greateft refemblance to this of Killoffy; but the fquare bafe only of the tower at Glendaloch joins the church, and the whole tower at Saxum is round from the foundation*. In the ifland of Zante is, or was till lately, a Greek church exaétly on the fame conftruCtion with this; alfo feveral others in various parts of the Levant+. The infulated réund towers, and the fmall old churches difcovered in Ireland, with ftone roofs and circular arches, as thofe of Cafhel and Glendaloch, and thofe in England called Saxon, as well as thofe in Spain named Mafforabic, bear a great refemblance to each other, and are apparently of the fame origin; being all, moft probably, conftru€ted on the model of the Grecian archite@ure, but not in that noble ftyle fo confpicuous in the monuments of ancient Greece and Rome, but in the degenerate ftyle of the latter Greek empire, from the time of Arcadius at the beginning of the fifth, to the clofe of the tenth century.

Swinburn’s Travels in Spain. it asa Roman empires, were undoubtedly ignorant of the art of con- ftructing edifices of lime and ftone; it muft therefore have been from the inhabitants of the fouthern parts of Europe that they ob- tained that knowledge, and the Grecian and Roman ftyles of _ archite€ture of the middle ages became diffufed through the weft of Europe prior to the ninth century; as well from the zeal of the Greek and Roman miffionaries, as from the fpirit of pil- grimages to the holy land. As early as the” middle of ‘the feventh century the Greek architeQure was introduced among the Anglo Saxons by Greeks, who followed Theodorus, Archbifhop of Canterbury. By the intereft of Theodorus thefe Grecians eftablifhed a fchool or aca- demy at Creekelade, or Greekeflade, in Wiltthire, and ereéted that church in the Grecian architeQure about the year 670*, refem- bling which the church of Hexham was founded by Wilfred anno 6744, and the church of Weremouth by Benedi& in 675t. How- ever it doth not appear that the Grecian and Roman archite¢ture were common in Britain prior to the eftablifhment of the academies at Cordova and Otranto. For about the year 759 an academy was eftablifhed at Cordova by the Saracenic Pr.sce Ahdoulrahman, for the ftudy of agriculture, geometry, aftronomy, architeCture and phyfic, by profeffors brought from Greece, Conftantinople, Egypt and the Eaft; which academy, during the —_ and tenth s centuries, * Grofs’s Antiq. vol..1. Godwin’s Eng. Bifhops, page 54, 558, 560. + Godwin’s Eng. Bifhops, p. 560. + Grofs’s Antiq. vol. 1, [ 78 ] centuries, was much frequented by the ftudious of all nations and religions in the Weft*. Auso, between the years 843 and 882, Charles the Bald efta- blithed a fimilar academy at or near Otranto in Italy, and fupplied it with learned men from Greece, principally prieftst. In this feminary the Anglo Sexons maintained and educated a number of their youths, at the defire of Alfred the great, and through the intereft of Plegmund his tutor with Pope Marianusf. Burt the Irith in thofe periods, not being under the dominion of the Roman pontiffs, would not be very defirous of ftudying either at Rome or in Italy, but chiefly applied to the Mafforabic and Gothic Chriftians, and reforted to the academy of Cordova. A circumftance which has caufed the inhabitants of this ifland to look up to Spain with veneration§, and pilgrimages from hence to that kingdom were frequent down to the fifteenth century. From thefe academies the Grecian and Roman architeGture of the middles ages became diffufed throughout the weft of Europe, and divided into various branches among the feveral nations, by means * Abulfud Amal.

Re weg means of the clergy and other learned perfons,; who brought home with them certain foreign artificers, compofed of Greeks and Italians, and Greeks and Spaniards formed into fraternities of architeéts, and who in fubfequent periods joining thereunto French, Germans and Flemings, obtained papal bulls from their encourage- ment and particular privileges, became corporate bodies, and ranged from one nation to another, under the denomination of Free Mafons*. To the firft of thefe fraternitics we are indebted for the Roman, Saxon and Irifh architeture of the middle ages, and to the latter for the various fpecies of the Gothic, to the clofe of the fifteenth century. Tue feveral branches of the Grecian and Roman ftyle during the middle ages, though they preferved a general likenefs of their original, differed in fome refpe&t from each other, according to the genius, tafte and manners of the people among whom they were cultivated. The Roman, Saracenic, Mafforabic, Saxon and Irifh, had fome peculiar traits which fpecified the nation in which they were erected. x Tue Saxon churches were generally. reCtangular edifices, ter- minating in a femicircle at the eaftern end, and their roofs low, {carcely vifible above the cornice. ‘The fteeples, when they had any, were generally fquare, and placed either at the welt end or fides; though fome, not common, were round. And they had generally under them a cript or under croft, for the prefervation of * Wren’s Parentalia. [ 8 ] of facred reliques, &c. after the manners of the Romans and Italians *. Tue Irith alfo had cripts to their ftone churches, but thefe cripts were not under but upper crofts, fituated in the roofs be- tween the circular ftone ceiling and the ftone pediment roof; as in the churches of Glendaloch and Cafhel, agreeable to the cuftom of the Mafforabic Chriftians, who ftill ufe fuch apartments as choirs+. On this account the roofs of the Irifh churches were raifed remarkably high, and gave them a different appearance from thofe of the Saxons. Another diftinguifhing feature between the Saxon and the Irifh architeture, was the infulated round tower of the latter, which the Anglo Saxons do not appear to have ufed, any more than the Italians, at leaft very f{paringly; but numbers are to be found near the old Greek churches in the Eaft, which were by the Moflems adopted as minarets to their temples, and watch towers to their fortrefs,; as appears from feveral ftill re- maining on the Ebro, and in other parts of Spainf. Tuovucu it has been obferved that the Greek architeCture had been introduced into Britain about the middle of the feventh cen- tury, yet flone buildings were by no means common till towards the clofe of the ninth; for St. Paul’s Church, London, continued of wood to the year 900, when Bifhop Theodred rebuilt it of ftone * Grofe’s Antiq. vol. 1. + Swinburn’s Travels in Spain. { Ibid. —_- bt aac ftone with an under croft after the Roman archite@ure, called fince St. Faith’s Church, which church was alfo again rebuilt in the Gothic ftyle in 1087*: Tue. Irifh do not appear to -have adopted this fpecies of archi- teGture, or to have built in lime and ftone, prior to the ninth cen- ‘tury. The firft edifice of this kind was moft probably the oratory of Malachy, about 850; towards the clofe of which century the churches.of Glendaloch were erected and. ornamented in the tafte of the northern nations}.

From this period, ftone-roofed criptic churches and round towers became common in | this. ifland; and .continued the reigning tafte for ecclefiaftical buildings until. the introdution of the Norman and Gothic archi- teGture in the beginning of the twelfth century, when the ftyle was difcontinued.

Bifhops. + Ledwiche’s Irith Antiquities. + Harris’s Irith Bifhops. § Ledwiche’s Irifh Antiq. | Smith’s Hiftory of Cork, vol. 2: [ 8 ] fider the period in which the church under confideration was founded, Ir we give credit to legendary accounts, St. Patrick founded’ an abbey here for his nephew St. Auxil, who died in 454, and who gave mame to the church, that is, A7//-auxarle, Kill-afatlle, or Ceall-ufall, afterwards Kil/-uff and Killofy*. But leaving fuch relations to the biographers of Saints, it may not be unneceffary © to obferve, that the diftri@ in which this church ftands was anciently denominated Magh Laifagh, fituated in Magh Libhiadh, the old name of the N. E. parts of the county of Kildare; and part of the demefne lands of the O’Kelly’s, chieftains of the coun- try, who in the eighth century are faid to have founded a mo- nafiery here; the church and other buildings whereof, according to the fafhion of the country, were moft probably erected of wood, and denominated from the diftri@ Ceallmagh Lazfagh or Czl/morlaiffy, and from thence K7//moloffy or Killoffy, or the Church of Magh Laifyt. This monaftery in 833 was burnt to the ground by the the Danes, and being rebuilt, was a fecond time with Cillcullen or Killcullen deftroyed in 984 by the Danes, under the command of Ambrofe fon of Godfrey, when one thoufand perfons were taken prifoners, and the intire country deftroyed§. After this period * Arch. Monaft. ex M'Geog. p. 658. + Pfalter of Cafhel, Keating. $ Ann. 4 Mafters. § Tbid. [ 83. ] period the church was rebuilt of lime and ftone, in the then new mode of architeGture, of which the tower ftill remains a monu- ment, as in the annexed view. Tue ancient wooden churches, and other edifices of the Irith, being eafily deftroyed by fire, were conftantly expofed to the depredations of the Danes and other roving plun- derers. There were no other means of faving the facred re- liques, veftments, &c. of the churches, and the wealth of the inhabitants, than by hiding them in fubterraneous caves. The method therefore of building churches entirely of ftone, with upper crofts; was a great improvement, as it gave a place of fecurity to the goods of the inhabitants, as well as to the facred utenfils; for the churches being entirely of ftone could not be eafily burnt; and the entrances into the upper crofts, being only by narrow newel ftairs, or by ladders through ftone trap doors, they could not be plundered without pulling down the building, which in thofe defultory expeditions they had feldom time to do. On the arrival of the Englith, the diftri@ of Magh Laifiy in Naafe O’Felim, in the country. of M‘Caélan or Kelly, with its church, was granted to Maurice Fitz Gerald by Henry the Second *, who erected a caftle near the church, fome remains of which are ftill vifible. From this period Killoffy became [L 2] a parifh * Ware. Sir John Davis. [ 84 ] a parifh church, which during the conteft between the Irifh and Englifh was laid in ruins, and continued in that ftate for feveral years; but it has lately been repaired for divine fervice, by a grant from the board of Firft-fruits. On the weft end of the church, under a rifing ground, are a number of fubterraneons artificial caves, in a dry fandy foil, with pediment roofs, and communicating with each other by {mall apertures. One of thefe caves, near the church, had its fides com- pofed of ftone, and covered with flat ftones, in which was found part of a quern and the bones of fome fowls. The other caves have no other wall or covering than the native earth. Thefe caves, with others of a fimilar nature found in feveral parts of Treland, were the granaries or magazines of the ancient inhabitants, in which they depofited their corn and provifions, and into which they alfo retreated in time of danger. In the Brehon Laws they are mentioned under the name of Log, and by thofe laws a fine was inflied on any perfon who ftole any provifions or goods out of them*. Thefe granaries are thus defcribed by a Danifh captain of the ninth century in the Iflandic annals: “ Leifr going a pyrating “ towards the weft, infefted Ireland with hisarms. Here he found “ large fubterraneous caves, whofe entrances were difmal and dark, but on proceeding he faw the glittering of the weapons, “ which the foldiers within held in their hands. Leifr killed the men, “and brought the fwords away, together with a great quantity of “ other 14 * Afdad lan log legad creice, viz: Afda lan log legaide ereachadh. bias: “‘ other riches; whence he was afterwards called Hiorlesfr, or “ Leifr of the Swords*.” Thefe caves were ufed as granaries long after the arrival of the Englifht+; -and numbers of various conftructions have been from time to time difcovered in feveral parts of the kingdom. Thofe at Killofly feem to have belonged to the ancient monaftery, and were within its inclofure. * Antig.
