A NEVv' UNIVERSAL DICTIONy\RY OF ARTS and SCIENCES, LIGHT-HOUSE. LIGHT-HousE,. in the Mantle, is a building or watch- ■ tower erefted upon the fea-(hore, to ferve as a landmark to mariners in the night, to avoid any roclis or other dangers. The hght-houfe is generjUy a high tower, having at the top an apartment called the lantern, with windows on all fides, to exhibit the light made within it by the flame of an open fire, or by lamps or candles. Ii is frequently of fervice to navigation, to creft lighr-lioufes upon infulated rocks rifing from the fea, to warn {hips of their approach to fiicli rocks. Of this kind are the Eddyftone rocks off Plymouth, and the Bell rock at the mouth of the Forth in Scotland. In thefe fituations, the heavy fwell of the fea, when agitated by a ftonr, ftrikes with fuch force againll the building, as to require every precaution to feciire them from being over- thrown by the continued action of fo powerful an enemy. The Eddyftone rocks being the molt celebrated, as well from their peculiarly e.Kpofed fituation, as from the great inge- nuity difplaycd in the conllruClion of the light-houfes erected at different periods upon them, renders them deferv- ing of particular defcriptioii. The hiftory of the different ereilions has been already given under the head of Eddv- STONE. We here iiitend defcribing the conftruftion of each, whir.h will be a fummary of all the different kinds of light- houfes of wood or ilone. Mr. Winllanley's light-houfe was begun upon the Ed- dyftone rock in 1696, and was more than four years in the eretlion, from the many interruptions of the wind, which from fome quarters caufcs the fea to break over thcfe rocks with fuch violence, as to prevent the poffibility of landing upon them, though the lea around is very quiet. This is occafioiied by the rocks being open to the fwell from t!-;e Great Atlantic ocean, or from the Bay of Bifcay, in all the fouth-wellern points of the compafs ; and is in- creafed by the form and pofition of the rocks, which have Vol. XXI. a regular (lope to the fouth-weft from the deep fea to tlif rock upon which the houfe is erefted, and which, therefore, receives the uncontrouled fury of thefe feas, meeting no otlier objea to break upon, and the'effeft of fo great an extent of water, caufed by the hard S.W. winds, continue* for many days, though fucceeded by a calm, and breaks frightfully upon Eddyftone. When there is no wind, and the furface of the fea appears fmooth, Mr. Winftanley's light-houfe appears, from an engraved plate of it, publifhed by himfelf, to have been a ftone tower with 12 fides, rifinx 44 feet above the higheft point of the rock, which is in- clined fo as to be 10 feet lower on the oppofite fide of the houfe. The tower was 24 feet in diameter. At the top were a baluftrade and platform : upon this eight pillars were erefted, and fupported a dome of the fame diameter as the tower. From the top of this arofe a fmaller oftagonal tower, I J feet in diameter and fcvcn in height ; and upon this was the lantern to feet in diameter, and \i high, containing the lights. It had a gallery or balcony furrounding it, to give accefs to the outfide of the windows. The whole was fur- mounted by a fanciful iron work with a vane. The entry was by a door at the bottom, which was folid ftone, except the aperture for the ftaircafe, 12 feet in height. Above this were three floors, the loweft being the ftore-room, the next the flate-room, and the third the kiichen. Thefe occupied the height up to the level of the platform, or open gallery above- mentioned. The dome above this contained the lodging- room, and the oftagon above it the attending or look-out room, immediately beneath the lantern. This edifice was, as before-mentioned, more than four year* in erefting. The firft fummer (for it is only in this feafon the rock is ac- cefTible) was fpent in making J2 holes in the rock, and fattening 12 great irons to hold the future work. In the fecond year, a folid pillar 14 feet diameter, and 12 feet • B high. 444002 LIGHT-HOUSE. high, was built as a core or centre for the buildinfr. Thi> third year the pillar was incrcafcd to i6 feet diameter, and all the work was raifed, which to the vane wa^s at tliat time So feet. The workmen lodged in the hoiife foon after Midfummer, but were by bad weather iniprifoncd 1 1 days before a boat co\ild relieve them. A lipht was exhibited on the 14th of Nov. 169S. But findin^T tliat the fea frequently- broke over the lantern, in the fourth year tlie whole building was encompafled with a new work of four feet in ihicknefs, made folid for near 20 feet high, and the lantern was raifed 40 feet higher than at firft, making it 90 feet to the top of the cupola of the lantern, above which the vane rofe 22 feet. " Yet after all," Mr. Winftanley fays, " the fea in dorms flies in appearance 100 feet above the vane, and at times doth cover half the fide of the houfe and the lantern, as if it were under water." The joints of the additional ilone work of the fourth year, appear to have been covered with an iron or copper hoop cncompafling the building, to prevent the fea wafhing out the mortar. The building with- stood the walb of the fea only till the year 1703, when the inventor, being at Plymouth to fuperintend fcm? repairs of the building, went off to it on fome of his friends intimating the danger of the building, from a florm which fcemeJ coming on. He expreifed a wifh that he might be pre- fent ill tlie mod violent ilorm which ever blew, to obferve its elfctt on the (Irufture. In this he was too amply gra- tified, for on the 26th of November a violent (lorm arofe, and the next morning no velh'ge of the light-hoiife remained, except fome of the irons which were fallened in the rock, and a piece of iron chain, which was jambed faft into a chink of the rock, and nothing was ever afterwards found. Thus perifhed the firll light-houfe with its ingenious, but unfor- tunate, builder. A Welt Indian fiiip was loll on the rocks foon after the light-houfe was overthrown. Thiscircumdance, and the great utihty of the light while exhibited, ftimulated the Board of Trinity houfe, who bad tlie manaijcment of the building, to ereft another, and an aCt of parliament, of the 4th of queen Anne, was pafTed in 1706, to enable the Board of Trinity houfe to raife duties on ihips to rebuild it, of which they granted a leafe of 99 years to Capt. Lovel, as be engaged to build and maintain the houfe. In July 1706, the work was begun under the direction of Mr. John Rnd- yerd, who was at that time a lllk mercer on Ludgatc hJl, London, but who appears to have pofTeffcd much ingenuity and mental refource. He, like Mr. Winflanley, publiflied a print drawn by B. Leus, aud engraved by J. Sturt, which informs us, that it.was a conical fruftum of wood, formed of 71 upright beams, united together by bein^ bolted to cir- cular kirbs of woodwithinfide, upon which kirbs the floors were framed. It, in fome degree, rcfembled an inimenfe conical c&Pti, but without hoops : the diameter at the bafe was 23 feet, at the top 15 feet, and its altitude, from the highcll point of the rock to the top of the upright, was 62 feet. At the top of the buiidirg was a balcony, furrounded by a railing, and in the centre ot the area thus formed the lantern was fituated. It l;ad windows on all fides, asd wj.i of an oflagonnl £gure, 10 feet in diameter, and 13 high, furmounted by a dome with a fimple ball at top, inftead of the fanciful iron work ■vvhich ornamented tlic lirft edifice. Mr. Rudyerd, from prin- ciples totally different from thofe of his predeccfTor, made his building quite plain, without the leall projection or orna- ment on which the water could ail when dafliing againft it ; and he omitted no precaution of uniting all the parts toge- ther, and fallenin^ the whole to the rock. As the furface of the rock was naturally inclined, and the whole building would have had a tendency to Aide down it, if merely placed !;poa it, as Mr. Winitanley's was, Mr. Rudyerd wifhed to reduce its furface into level ftcps, Upon which each timber would have a horizon*.;! bearing ; but finding this to be the mod difficult of the whole undertaking, it was imperfedlly executed, only five deps being cut, and thofe did not t;ike out all the inclined furface ; however, it was fufficicnt for the purpofe. The building was filled up quite folid for 19 feet from tlie lowed point of the rock, and, excepting the well for the (lair-cafe, was folid to the height of 37 feet. The folid was formed of three beds of moor done, with drong floorings of timbers between each bed, to unite them with the externid uprights. The lower bed cont.iiiied five coui les of done, arid was live feet thick ; the fecond was the fame, and the third was four feet thick, containing four courfes. The whole eredlion, in addition to the weight of this done, which was about 280 tons, was fecured to the rock by 36 iron cramp.s, part of them arranged in a circle about a foot within the ex- ternal uprights, and the remainder, which were fmaller ' cramps, in an interior circle three feet didant from the former, to hold down the floors of timber which had the done beds between them. In the centre of the building a dronij . jnad was eredted, feciu'ed by two cramps to the rock at the hottom, and rifing above the folid to the height of 48 feet, being united to I'lc framing of each floor it pafled through, and thus forming :i central axis to flrengthen the whole. The houfe above the loiid contained four apartments, the lower being the (tore room, the next the date room, the third the bed chamber, and the fourth the kitchen, immediately be- neath the lantern. In the manner of fixing; the irons to the rock, upon the duration of which the fecurity of the whole work depended, Mr. Rudyerd fucceededmoft admirably. The holes in the rock were made by drilling two holes rather di- verging from each other, fo that they would be an inch more afunder at I j or 16 inches depth, than on the iurface of the rock. A third hole being drilled between thefe two, and the three being broken into one, formed a hole larger at the bot- tom than the top. The iron cramp was formed of two pieces, which, when laid together, were of the fhape of the hole, but when feparated, one was larger at the bottom than the top, and the other fmalleft at the bottom ; therefore the former being firll put down into the hole, and the latter driven in by the fide of it, wedged it fad, and both being united by the fame bolts which attached them to the timbers, ren- dered it impoflible to draw them out. They were put in their places hot, and a quantity of melted tallow being firit poured into the hole, when the hot irons were put down the tallow ran over on all fides, and thus certainly filled up all cavities. A quantity of coarfe pewter, made red-hot, was now poured into the cavity round the irons, and, being a heavier fluid, dif- jilaced the tallow, and filled the fpace round them completely, the tallow efFedlually preventing the entrance of the fea water into the moll minute cavities. This method is worthy of record, as it may be applied to many other ufeful pur- pofes. Mr. Rudyerd, as before-mentioned, began his ope- rations in July 1706 ; in July 1708, he had fo far com- pleted it as to exhibit a temporary light ; and the whole was complet^'d in the following year. This building had fiime repairs of its timbers in 1723, and again in 1744, when a violent dorm had carried away a great number of the up- right timbers : but it fhewed itlelf, in the courfe of 49 years, to be a very excellent condrutlion of its kind, and only liable to dedrudtion from the porilhable nature of its mate- rials, or the cataltrophe which awaited it on the night of the 2d of Dec. 1759, when one of the attendants, entering tfie lantern to fnuft the candles, found it in flames, and, not- withdanding every exertion, the fire communicated to the uprights, and barntd downwards. The unfortunate men de- fcendcd LIGHT-HOUSE. fcended from room to room as the fire increafed, and were at lad obliged to take refuge, from the fall of burning tim- bers, in a cavity of the rock, from which they were relieved by a boat the next morning. The wind, unfortunately, blew from the eaft, and though it caufed fuch a fwell as to pre- vent landing, did not break on the houfe fo as to extinguifh the fire ; and thus, in a few days, the whole was deftroyed, except the iron cramps in the rock. It is remarkable, that whilil; one of the light keepers, at the commencement of the fire, was looking up at the fire in the cupola of the lantern, a body of melted lead (howered down upon him, and he declared a quantity had palTed down his throat into his ilomach. He lived only 1 2 days after being talien on fhore ; and on opening the body, a mafs of lead was taken from the Ilomach, weighmg more than feven ounces. The curious fact, of his having 12 days furvived fo alarming an accident, was communicated by his attendant furgeon, Dr. Spry, to the Royal Society, bat the ciicum- llance appeared lo improbable, that it did not, at firlt, meet that credit, which future experiments on animals proved he was entitled to. On the news of the fire reaching London, the proprietors (for by the fde of Capt. Lovel's original leafe, the property of the light-houfe was now in many hands,) immediately took meafures to reftore it, and appointed one of their mem- bers, Mr. Rob. Wefton, to the fole managefnent of their affairs, and he being recommended to Mr. John Smea- ton, F. R.S., by the prefident 01 the Royal Society, employed this gentleman to devife the means, and fuperintend the erec taining the fire-place L, from which the fmoke afccnds by,a copper funnel m, through the bed room M and lantern N, to the ball on the top of the cupola O. The afcent from room to room is by the perforations through the middle of each floor, a moveable ftep ladder being ufed for the attend- ants; but llore may be drawn up from the lower room into any other. P is the railing forming the balcony ; its floor is covered with v.ry thick (beet lead, turned down over the cornice Q, which furmounts the co- lumn fif the building. R is the ftone bafeiiient of the lan- tern, and N the glazed part : the cupola O is fupported by eight caft-iron ftandards, bet^teen which the copper win- dow frames are fixed : the ftandardi have claws at bottom, which are fcrewed to flat iron bars relting upon the llone work. By this means the whole lantern is framed together ; and to ftrengthen it, the window frames are call with di- agonal bars, as fiieun in Jg. 2. The whole lantern is held down by eight bolts at its angles, paffing down through the balcony floor ; one of thcfe is feen at ^ : S is the door to the balcony. The lantern is lighted by 24. candles ar- ranged in two iron circles, one fix feet four inches diameter, containing 16 lights ; and the other, three feet four inches diameter, holding eight candles. Tiiefe circles are fufpenced by cords going over pullies, fo that they mutually rife and fall parallel, and counterbalance each other. By this arrangement either circle can be diawn down to fnuff the candles, which is done every half hour, without lofino- the whole light. Having thus defcribcd the general outline of the building, the minutia of its ccnllruclion comes next tion, of a new building. Mr. S., whofe originality of genius, to be defcribed, and the manner of uniting the ilones com- and foundnefs of juiigment, have fince been fa generally pofing it. The feCtion,_^. 2, fhews the feveral fleps wiiich known, was at that time juft entering into his profeflion as a were cut in the rock to engraft llie ftone work upon, civil engineer, but immediately devoted himfelf to the confi- J^'S^- I, 2,3, Sec. denote the different courfes of llone, eacii deration of the light-houfe, and foon determined upon of whichniakes a level furfacev/ich the ilep it is fitted into, eredling a ftone building ; and reafoned, that by making the The feventh is the firft com.plete courfe. Fig. 2. is a plan building very heavy, and uniting all the ftones firmly together, he ihould obtain fuch a weight and ftrength, as would firmly refift the united action of the wind and water. He determined upon dovetailing the ftones together, as being a more fecure method than cramping with iron, and not liable to inter- ruption from the work getting wetted, as would almoil: un- avoidably happen in fuch an expofed fituation. On the whole, tlie building he erefted, and which is now ftanding, may be confidered as the moft perfeft light-houfe in exiftence, and gives exampies of the beft kinds of mafonry. We have there- fore given drawings of it in the FUle of Light-houfe, which are taken from a fuperb work in foho, publilhed by Mr. Smeaton in 1791, entitled " Narrative of the Building, and Defcription of the Conftruction of the Eddyftone Liight of the rock, (hewing the courfes i, 2, and 3, laid in their places, and exhibiting the dovetails which are cut in each ftep to hold the feveral ftones in their places ; and thefe ftones are fo formed as to enlock the others with them iu a manner which will prevent any ftone quitting its pofition. The dark fliaded ftones are moor ftones, while the lighter forts are Portland ftone. Fig. 4. is a plan of the feventh or firft complete cOm-fe, ftiewing a central ftone with four dovetails uniting it to four others, and thefe tying in the remainder. All the folid courfes arc laid in this manner to the fourteenth, which, as before mentioned, completes the entire folid. Every courfe is laid in fuch a manner upon the one beneath it, that all the joints break each other, as mafons term it, that is, immediately above and below the The feveral courfes are retained upon each other, to prevc.it them Hiding fideways, by means of joggles, which Ere plugs or cubes of h^rd bl.ick marble, (hewn by the dark fquares m fig. 2, and in the plan, jfj. 4, to be received one-half through every two adjacent courfes.

Above the folid, a new fyilem of building was necclTanly adopted: the lower courfes were coinpofed of Portland (loncs to fill up the centre, and moor iiones, as being nioie durable, to make the outfide. The whole of the upper works are of moor llone ; and dovetailinjj hci'g no longer pradlicable, the Hones :re united by iron cramps and joggles, as Ihevvn in^^. 7, which is a plan of the upper or bed-room M. Each ftone is here feen to have an iron crump to join it to its neighbour, and has a fmall marble joggle to unite it with tliat above it. The ver- tical joints are rendered impervious to water, by cutting a notch between every two adjuceut Hones, fo that when they come togeliier it forms a hole of a lozenge fliape, and a piece of llune being put dovyn into this hole with mortar, makes a perfcA joint, at the fame time increafing the bond of the iiones. This kind of joint is partly feen in_y?f. 8, at n, but one-half is hid by the iron cramps r, r, extending over every joint.

The (lones of the different floors arc dovetailed together, as in ^/fj'j. 5 and 7, and are rather arched on the lower fide, as flicwn in Jig. 2. To retain the thrull of thefe arches, every courfe trom vvhich a fioor fpriiigs, is bound by an eiidlefs chain inlaid in the fione work, as in Jir. j, and run in folid with lead. The chain is fiiewn enlarged in Ji^. 6. Fig. 7. is a plan of the bed-room M, (liewing the diljiohtion of ihe three cabin beds i, I, lit, with a window between each.

On this account we iliall briefly follow Mr. Smeatoii through his narrative, though it relates- circumllances which, if recorded in the account of a com- mon building, wijuld appear impertinently minute. The feaibn when Mr. Smeaton firll took up the bufmefs of the liglit-houfe not being favourable for a vifit to the rock, he did not attempt it till April 1756, before which time he had deligned the general plinciplcs of the building. He fcund upon the rock the irons of both the former erections, and fcveral of the moor Rones of the late building lying in the gut, wiiicii was a narrow channel of twelve feet deep be- tween the houfe rock, and a reef of rocks to the well ward, in which channel the boats coming to the houfe could lie in fair weatlier. His firil vifit was employed in obferva- tions on the rock, ancFin experiments of the time rcquilite to drill and pick holes cf a certain dimenfion, that he might elliraatc the time necelTary to complete the work on the rock. In fucceeding voyages he took dimenfions of every part to enable him to make an accurate model, to which he could ada'Jt a model of the intended building. The unfa- vourable days at fea were employed on fliore in examining the (lone in the country round, a convenient fituation for a work-yard, &c. The dimenfions of the rock were taken by the foliov/ing means : He fiiced up the circle of ?. theodolite, with its index, in the centre of tlie rock, and levelled it with ti e fpirit-level ; a light rod was fixed to the index, long enough, when turned round, to reach all parts of the rock ; it was provided witli a fpirit-level to (hew when it Hood horizontal. It is obvious that this rod, when turned round, would defcribe a horizontal plane, and the depth of any pcint of the rock beneath this plane was afcertained by a rod fel u]) vertically upon the point in quelUon, and ap- plying the horizontal ruler to it. The divilioiis on the ver- tical rod fliewed the depth ; and tite divifiou of the horr- zontal ruler fliewed the diitance from tlie centre, and the degrees of the theodolite circle pointed out the direclion. By thefe means the jjofilion and altitude of thirty-two principal points were obtained, which were well marked upon the rock, and a line being ftrctched from one of thelo points to another, pave the means of determining the pt»- fition of the iron ftanchioi;S, or any thing elle vshieh was remarkable. Having thi:s, ill ten voyages, made all tl.«; nccedary obfervations on the rock, and determined upon re- gulations for the management of the work, he returned to i^ondon, and, in his way, vifited the various ftone quarries in Devonlhire, and the illes of Portland and Purbeck. He was employed, till the month of July, in making cxaA mo- dels of the building, when he returned to Plymouth, where he found a velfel, the Neptune Bufs, whi. h had been fitted up for exhibitini; a temporary light during the period of rebui'diiig the hoiifc. From fome mifundcrC.anding be- tween the Board of Trinity and the proprietors, this veffel was not eu-.ployed in this manner, but was devoted to Mr. Smealon's ufe, who immediately began tlic work.s upon the rock ; mooring the Bufs near the rock to ferve as a retrejrt for the workmen, who were frequently driven off by the waves. In the month of September the three Icwer ll^ps of the rock wore completed, and the upper ones in a Ihite of great fur wardnefs ; after which time, bad weather pre- vented much more being done that year, and In November the Bufs left her moorings to return to Plymoutb, in which voyage (lie was driven to fea, and narrowly efcapcd (hip- wreck. Thus concluded the i perations of the year 1756.. The winter feafon was pafTed in preparing ftone work on (hore, m building boats, and, by Mr. Smeaton, in a long and valuable ieries of cxperin.ents on the different kinds ct cements, which could be applied to the building. In May 1757, the Bufs was carried out and moored, and on the 1 2th of June the lowell and firll Hone was kid in its place ; from the great uncertainty of the weather every ftone was fo contrived, that it was of itfclf in a condition to rcfiit the wafh of the fea,even when it was immediately laid, and be- fore it was hardened. For this pnr^ofe, eath (lone had one or two holes drilled through it before it left the work-yard, and this hole being continued a few inches into the rock or the llone ben.;ath, a ilrong trenail, or oaken pin, was driven through it, to pin it fait in its place : as liie dove- tails did not of courfe fit perfecVy clofe into each other, but left fpace for the mortar ; notches were cut in the edijes of each llone to receive ftrong oak wedges, which lield them firm until the mortar came to its folidit.y. As a further precaution to defend the nuirtar, all the outward joints were coated over with plafter of Paris, as a temporary expedient. The woi-k went on r.ipidiy in tliis manner, and the (ecund courfe was nearly fct in a few days ; but a ga'e fprang up, which obliged them to quit the work, le?,viiig a few Hones of the fecoiid courfe, which could not be fet, lowered down into their places, and chained Hrongly to the rock, by lines inferled into the holes made in each of the Hones, to lift them by ; and one o^ the moll expafed was fecured, by laying upon it, when in its dove-tail, a weight of lead of five cwt. in form of a hemifpherc. A llorm came on, and it was afterwards found, that this weight had been lifted by the waves, fo th.it the Hone beneath it had efcaped and was loll, as were four others, from which circumftance the force of the fea on the rock may be imagined. New Hones were immediately prepared, and the work renewed. In tl'.e progrefs of the work, it conilantly happened, after all pre- cautions, tliiit the cement was waftied away in particuiair I places. LIGHT-HOUSE. places, and it was always repaired the firft opportunity with Pozzolana or Dutch terras ; which repairs, if they with- ttood one rough tide, were never found to tail afterwards ; b'Jt fome places were found fo difficult, that it became ne- cefTary to mix oakum, chopped very Ir.'.all, witli tha mortar, and this method always fucceeded. On the i ith of Augult the Cxljafement courfes were completed, and the firll entire courfe, N"' 7, was begun. All the (lones for this cuurfe were fitted and put together in the work- yard, as Ihewn in Jig. 4. They are numbered, fo that after being taken to pieces, they could be rellored to the lame relative pofition on the building ; but to do this accurately, while they were in the work-yard, radial lines were drawn from the centre to the circumference, fo as to iuterfect each ilone ; and concen- tric circles were drawn through the middle of each tier of Itones. Where any of thefe lines eroded the joints, a nick was fawn in the edge of the Itone, that the mark might be felt as well as feen ; and by the coincidence of thele lines the ftones were fet with the greatell accuracy. On the llones arriving at the work, the central ilone was firll fet; the hole to receive the centre joggle was cut through the centre of courfe fix, and the joggle fet up therein, as fliewn \njig. 2, and the centre flone ot courle feven let down upon it, a mortar bed being made beneath. When the ftone was thus fixed, the joints round the joggle were iiiled in by grouting, which is mortar made very thin and poured in from ladles. Tiie four Hones furrounding the centre were now fet, and the work proceeded thus to the circum- ference, every Ilone being wedged snd trenailed as foon as fet, and the joints grouted. To fix the eight fmaller joggles, they were let, wedged, and grouted into their holes in the lower courfe ; but the holes for their reception in the lower fide of the upper courfe, being only cut half through, did not admit of wedging ; they were therefore fixed by the mortar only, as much being put on the top of the joggle as would nearly fill the hole, but not quite, and the remain- der was introduced through a hole previoufly drilled through the ilone, and forced down by a wooden ramrod. The mortar ufed in the building was compounded of equal portions of lime and pozzolana. The lime was burned from the blue Lyas limellone found near Watchet, a fmail feaport in Somerletlliire. It was carried out in tight calks, which W'ere opened at the rock, and a fmall quantity beat up in a ilrong bucket with a wooden peltle, and ufed imme- diately. The work proceeded in the fame manner without any deviation or accident, except now and then loling a few llones by llorms, until the end of September, when the ninth courfe, being completed, the work was given up for the year, and the Bufs left her m.oorings. During the winter, the buoy of the moorings for the Bufs was loll, but was recovered on the nth of May, 1758. Y,f t, before any work could be begun, the chains were broken, and the buoy of the anchors having got loofe, the moor- ings were loll ; much time being confumed in preparing new ones, it was the 2d of July before tiie work wa3 renewed ; but by the Sth of Auguil, the 14th courfe, completing the entire folid, was laid, and by the 20th the entry door was covered in, and by the 24th of September, the whole of the fohd, up to the ftore-room floor, was finilhed. Above this the method of working was totally altered, but not being now fo liable to the atlion of the fea, it became lefs difficult, r.nd requires lefs defcription. In addition to what has been faid before, the iron cramps were all filled in their places with lead, and a whole courfe was done at once, by putting each cramp into a kettle of red-hot lead, till it was equally hot. A fmall quantity of oil was poured into the holes ia the ilone, and the hot cramp put in ; this oil caufcd the lead, when poured in, to occupy every cavity in the ftone. On the 3cth of September, the work had arrived at the ftore-room floor, and here the iron chain, (hewn \a Jig. 5, was let into the ilone, and filled in with lead in the to.low- ing manner : — the chain was oiled before putting it in, and the groove divided into four parts by dams of clay. Two kettles were ufed, which together would hold lead enough to fill the whole groove, which was 1 1 cwt. In thefe the lead was made red-hot, and tv.o perfons with ladies filled the lead into the fame quarter of the groove. As foon as it was at all fet, they removed one of the clay dams, and filled the next quarter, pouring the lead on the end of the firft quarter, till it re-melted and united with the fecond. The dam at the oppofite end of the firll quarter was now re- moved, and the third filled, and then the 4th. By this means the lead was all round united in one mafs. The centering for the floor was next fet up, and the floor partly put together, the outward llones being fet firil, and then the centre ones. When the firll room had been thus finilhed, Mr. Smeaton propofed exhibiting a temporary light during the winter, and, by fixing three floors in the well for the ilaircafe, to form ftore rooms, and lodging for two men : but this idea was given up, as it did net meet the approbation of the Trinity corporation, and .the work was, on the 7 h of October, left for the year, the floor being partly finilhed. The winter was Ipent in preparing the iron, glals, and copper work for the lantern ; and the fpring in un- iuccefbiul endeavours to recover the moorings which were again loll, and on the 5th of July the work was begun again. They found one of the llones for the floor, which was lodged in the ilore room H the year before, had been walhed dowR the well, and thence through the entry into the fea, though it weighed four or five cwj. The flones for the building had hitherto been railed out of the boats, by what are termed Jhears, formed of two poles, united bt top, and their feet pitched on the rock dole to the building, at a proper dif- tance alunder. A block of puUics was fufpeuded from the top of the two beams, to take up the Ilone. The fliears were fupported by a tackle called a guys, which was attached to the top of tile iliears, and hooked to the far fide of the building, fo that the Ilone, being raifed up frgm the boat by a windlafs fixed on the rock at Y, Jig. l, the guy was drawn in to fuing the ftone over the building. When the work got above tlie entry E, the ftones were landed into it, and drawn up the well X by a tackle fufpended from a fmall triangle fet over the well ; but when the floor was covered in, the hole in the centre being too fmall to let the llones come up, a fmaller pair of iliears were msde to lie upon tlie buiiding and rife as it advanced. Thefe were worked by a windlafs fet up in the ilore room H, and as they hung over the fides of the building-, they drew up the ftones clear of the wah. The work proceeded in this man- ner till the 17th of Auguft, when the laft piece of the cornice Q was fixed, which completed the i\liolecolumn,.and the workmen W'ere enabled to lodge in the building. The balcony rails P, and the Ilone bafement R of the lantern, were foon completed ; and by the 26th, the flairs and a!l the niafonry were finilhed. The iron frame of the lantern was next fcrewed together in its place, ail the joints being firft fmeared with thick white lead and oil to prevent them from ruftmg : it was then raifed up ou wedges a Imall height, and lead poured in the joint between it and the ftone to make a folid bed for it upon the ilone. On the 17th of September, the copper cupola O was fet up, by a parti- cular kind of Ihears made for the purpofe, the guys, in dif- ferent dircilions, being fatlened to booms projected out from the L 1 G L I G tlis feveral windows of the upper room. The next day the ball, which was douhk- gilt, was fcrewed on ; and by Ottober the i6th, an eleftrical'conduftor was fixed, which fiiiifhed the edifice. A Hght was then exhibited, which has been continued ever fince without any particular occurrence, or any accident produced by the inairy violent ftorms which Tiave happened fince. Mr. Smeaton has, in the title page of his narrativ..', given a reprelentation of the houfe in a (torm, as fcen tlu'ough a telefcope from Plymouth, when the waves dafh up againft the building, till they nieet the cornice O, ty which the water is thrown off in all directions in a white column, which envelopes the houfe like a (heet, and rifcs to at leaft double its height, though the top of the ball is loo feet above low water. See Beacon's. Light Infantry. See iNtANTny. When the light in- fantry companies are in line with their battalions, they are to form and ail in every refpeft as a company of the batta- lion ; but when otherwife difpofed of they may loofen their files to fix inches. The open order of light infantry is ufually two feet be- tween each file. The files may be extended from right, left, or centre ; in executing it, each front rank, man mud carefully take his diftance from the man next to him on that fide from u^iich the extenfion is made : the rear rank men conform to the move- ment of their file leaders. When light infantry men fire in extended order, it is to be a Handing rule, that the two men of the fame file are never unloaded together ; for which purpofe, as foon as the front rank man has fired, he is to flip round the left of tli- rear rank man, who will take a (hort pace forward, and put bimfelf in the other's place, whom he is to protcdl while loading. The extended order of light infantry varies according to circumftances and fitu^tions. They may fometimes loofen their files to three times the dillance of open order. But the general rule is to allow convenient intervals for the rear rank men to flip by, and return after they have fired. All movements of light infantry, except when firing, ad- vancing, or retreating, are to be in quick time. The officer commanding the company will be on the right, covered by a ferjeant ; the next on the left, alfo covered by a ferjeant. The youngell officer in the rear. In extended order the poll of the officers and ferjeants is always in the rear at equal diltances. In marching by files the officer commanding leads : by divifions each officer leads one. The fupernumerary officer, if there be one, is in both cafes with the officer com- manding, ready to obey any diredlions he may receive from him. The arms of light infantry in general will be carried floped and with the bayonet fixed. Flanking or advanced parties, however, or parties in particular fituations, may carry them trailed, and without bayonets, for the purpofe of taking a more cool and deliberate aim. When the light infantry is ordered to cover the line to the front, the divifions will move from their inner flanks round tlie flanks of the battalions, and when at the diflance of fifty paces, the leading flanks will wheel towards each other, fo as to meet oppofite the centre of the battalion, opening their files gradually from the rear, fo as to cover the whole extent of the battahon. The files are cot to wait for any word of command, but to halt and front themfelves. In this pofition, and in all pofilions of extended order, the poll of the officer com- jaanding is iu tbt rear of the centre, and the movements are to be regulated by the company belonging to the batta- lion, which governs thofe of the line. For a fuller expla- nation of light company manoeuvres, fee page 273 to page 281 of Infantry Regulations. Light infantry men, like huiTars, are frequently detached to act as fcouts on the Hanks, in the front, or with the rear guard of the body of troops to whicli they belong. They then acquire the appellation of ikirmifliers, and being prc- vioufly told off for tliat fpecific duty, they advance and form in the front in rank entire ; which is effeCled by each man from the rear rank placing liimfelf on the left of his file leader. The rank entire may be reforted to for various puipofes during the movements of one or more battalions, fince it may ferve not only to cover them from the enemy's obfervatioii, but in fome cafes, efpccially in foggy weather, will itlelf appear a larger body than it really is. Too much attention cannot be given to the organization of light troops on foot. They are very properly called the eyes of an army, and ought always to be confidered as indiipenfably necclfary. \AC,nr-Room, is a fmall apartment inclofed with glafs windows, near the magazine of a fliip of war.

To lighten a horfe, or make him light in the fore-hand, is to make him freer and lighter in the fore-hand than behind. If you would have your horfe light, you ought to keep him always dif- pofed to a gallop, when you put him to a trot ; and after gallopping fome time, you fliould put him back to the trot again.

See Bo.'VT. LiGiiTER-Mi-n. See Co.mi'any. LIGHTFOOT, John, in Biography, the fon of a clergy, man, was born at Stoke upon Trent, in Stalfordfliire, in the year 1602. He received his grammar learning at Moreton- green, near Congleton, Chefhiic, after which he was en- tered a iludent of Chrifl's college, in the univerlity of Cambridge. Here he applied hinilelf with much diligence, and made fo great a proficiency in claffical literature, a"d the fludies connefted with it, that he was reckoned the bed orator among the under graduates of the univerfity. At the age of nineteen he quitted the univerfity, and engaged him- felf as affiflaiit to his old fchool-mader, who had, at that time, removed from Chefhire to Repton in Derbyfliire. Having continued in this fituation about two years, he took orders, and fettled as curate at Norton-under-Hale-'., in Shrop- fhire : about the fame time he became chaplain to fir Rowland Cotton, and retided in his family. This gentleman, being a perfect mailer of the Hebrew tongue, engaged Mr. Light- foot in the fludy of that and the other Oriental languages. He followed his patron to London, and vvould have proceeded with him to the continent, but the living of Stone, in Stafford- fhire, being offered him, he preferred fettling there, as if like* which gave him an opportuinty of entering upon the marriage 4 Hate, L I G 1 I G ftate, which he immediately embraced. Here he found the means of ftudy exceedingly fcanty, and in the coiirfe of a few months religned the Hving of Stone, and removed to Horn- fey, near London, a fituation which he chofe, on account of its vicinity to the metropohs, where the fourccs of learning were very abundant. He was now a frequent attendant at the hbrary of Sion-college, which afforded hini tlie moil ample means of fuuplying all his literary wants. In 1629, Mr. Lightfoot pubhihed his tirft piece, entitled " Erubhim ; being enfy of accefs, affable, communicative, hofpitable, and charitable. Asa writer he was one of the moil ingenious, as well as learned, of our Englifh commentators, and has furniilied his luccciTors with very valuable materials in the lame line of ftudies: he had few equals, and no fuperiorin rab- binical literature; and in this branch of learning his celebrity was fo great, that many foreigners came to him for aliiilance in it. His works were coUeClcd and publiflicd in 16S4, in two volumes folio. A new edition of them was publifticd in or Mifcellanies Chriilian and Judaical, and others, penned for Holland in 16S6, containing aU his writings that had been the recreation of vacant hours." In i6^c, he was prefcnted originally given to the world, in the Latins lauguage, and S by fir Rowland Cotton to the reftory of Afhly, in Stafford- Latin tranflation of thofe which he had written in Englidi : fhire, and immediately removed to his parifh, in which he anda thii-d edition was publiihed at Utrecht in 1699, by .lolrn lived twelve years, applying himfelf with indefatigable dih- Leufden : this imprefiiou contained fome poilhumoiis pieces. gence in fearching the fcriptures, and in the performance of various duties attached to his office, as a confcientious clergyman. He was next appointed by the Long Parliament a member of the affembly of divines at Wellminller ; and as he could no longer relide among his parifhioners he re- ligned the reclory, but obtained the prefentation for a which were comprifed in a third volume. Thcie were, in the following year, publifiied in an 8vo. volume by Mr. Strype, under tlie title of " Some genuine Remains of the late learned and pious Dr. John Lightfoot." The doctor was not only indefatigable in his own purfuits, but an encourager of other learned mt-n in their's. He gave great aJlidarce in younger brother. He arrived in London in 1642, and was completing the Englifh Polyglott bible, by drawing up a almolt immediately chofen miniiler of St. Bartholomew's^ chorographical table prefixed to it, and by fuperintendin"- behind the Royal Exchange. In the afiembly of divines. which met in June 1643, Mr. Lightfoot became diflinguiflied for his eloquence in debate, and activity in bulinefs. He was friendly to the Preioyterian form of church government, which he declared in a fermon before the houfe of commons, he verily believed was " according to the pattern in the mount.". In 1643 he was appointed mailer of Catherine- hall, m Cambridge, and in the fame year he was prefented to the living of Much-munden, in Hertfordfliire. In 1644 he publiilied the tiril part of his " Harmony of the New Tetlament," with a plan of his whole deiign, and conti- nued afterwards to fend out, at different periods, the other branches of the fame work. In i6j2, Mr. Lightfoot took the (heets of tlie Samaritan verfion, as tiiey were printed : he atTorded much pecuniary alTiflance to Dr. Callcll in the publifhing of his Heptaglott Lexicon, which would other- w,fe have occaiioned Ins entire ruin for want of fupport from the learned world : and Dr. Lightfoot v/as tiie perfon who excited Mr. Fool to undertake his valuable work en- titled " Synoplis Criticorum." Biog. Brit. Gen. Biog. LiGHTiooT, JoHX, a dillinguifhed Britifli botanift, chiefly known as the author of the F/ira Scotica, was born in 1735. He was educated at Oxford, where he took the degree of Mailer of Arts, and having entered into holy orders, became chaplain to the late duchefs dcuager of Portland, " that great and intelhgent admirer and patronefs the degree of dodor of divinity, and went through all the of natural hiilory in general," as he jufily denominates her regular exercifes, on that occafion, with great applaufe. in the dedication of his book. He was recommended to IniGjijhewas chofen vice-chancellor of the univerlity of Cambridge, the duties of which important office he per- formed with exemplary diligence and fidelity. Upon the refloration of king Charles II. Dr. Lightfoot offered to re- iign the maflerfhip of Catherine-hall iu favour of Dr. Spur- ilovv, but upon his declining to accept it, our author ob- tained a confirmation from the crown of that place, and of his hving. For tliefe marks of royal favour he was chiefly indebted to the kinduefs of archbifhop Sheldon, who, out of pure refpe£l for his learning and talents, undertook to ferve him. Soon after this he was collated, through the interell of lord-keeper Bridgman, to a prebend in the cathedral church of Ely. In 1661 he was appointed one of the alTill- ants at the conference at the Savoy on the fubjeft of the liturgy, but he attended only twice, on account of the violence difplayed in the debates. He now gladly withdrew as much as polfible from the world, in order that he might fpend his time in fttidies to which he was attached, and which he piofe- cuted with vigour to tlielall. His publications would have been more numerous, but theexpetice of them was more than this illuilrious lady, whofe accomplifhments gave a lullre to her high rank, by his tafte for botany and conchology, as well as his courtly and afEduous manners, which, accompa- nied by an habitual pleafantry and cheerfulnefs, rendered his company generally acceptable. By her grace's influence, we believe, he obtained the reclory of Gotham, in Notting- hamfliire, and'fubfequently the hving of Cowley, is .Middle- lex. In 1772, the late Mr. Pennant, fo well known as a zoologilt, invited Mr. Lightfoot to be the companion of Ifis fecQiid tour to Scotland and the Hibrides, advifing him to undertake the "compilation," as he himfelf modeilly calls it, of a Flora Scol'tca, which Mr. Pennant offered to ufher into the world at his own expence. ' Tliefe generous and flatter- ing offers Mr. Lightfoot gladly accepted, and m.ade the mofl of tlie opportunity afforded him for " gratifying a fa- vourite affedion he had long conceived for the fcience of botany." He enjoyed " the enchanting profpecl," to ufe his own words, " of examining a country whofe vegetable produftions had been attended to by very few." Our lie c;iuid bear, and he never was fulTiciently patronized by the author v.'as jullly aware that a fingle fummer could by public to interell the bookfelLrs in his behalf. A fhort time no means be fulficient for the full Lccomplilhment of fuch before his death he was, however, requelled by them to col- an undertaking, nor would he perhaps have ventured upon iect and methodife his works, in order that they might be it, but for the afTiftance of " able and ingenious botaniils, prirttcd in an uniform manner. He died in December 1675, who had refided in that country their whole lives," who per- beforc he could accomphfh the talk required of him, in the mitted him " to examine their colledions, and freely com- "4th year of his age. Dr. Lightfoot was indefatigable in municated the obfervations of many years." Thefe were the ins purfuits, and extremely temperate in his mode of hving. late Dr. Hope, profeffor of botany at EJinbuvp-h ; the Jie .lived in the greateft harmony among bis parifhioners, Rev. Mr. (now Dr.) John Stuart of Lufs ; aud the Rev Df' L I G Dr. Burgefs, the venerable pador of Kirkmicliael in Dum- fncsfliirc : Un-ee men whofc urbanity conferred upon their beloved fcicncc her moll attractiNx- charm, as the writer of t.in can well telbfy. Mr. Sluail was the companion of onr travellers m their excmfion, and fnpplied eiich, in his own Inie, with muc!.\ learned information, refpeain j the Erfe no- menclature, as well as the real or fuppolVd ufes nnd hillory of t.he native animals and plan's. Thus Mr. I'ennant was miabled to prefix a compendious Fauna to the Flora of his friend ; and thus Mr. Lightfor.t found his r^ath made flraight and plani before him, and literally ftre'vved with flowers. He profited likewife from the communications of Dr. larfons, at that time profefTor of anatomy at Oxford, and ot Mr. Ya!den, an ingenious young man, vvhofe pre- mature death happened foon after. Thefe gentlemen had cultivated botany in thecourft- of rlieir medical ftudics at Edin- burg!!, the latter cfpecially, with eminent fiiccefs. When Mr^Lighttout's materials were got together, the library, herbarinm, and perfonal fuperintendance, of his fric-nd fir jlius at Oxford, under the eye of the profeffor, oi his fon Dr. J;din Sibtliorp, gave the fininiing IT or rather of rp, gavvT the tinilhmg ITrokc to his labours. Thus the F/ora Scotica became ready for publica- tion in 1777, when it appeared in two thick volumes 8vo. With 35, rather indifTerenllv engraved plates, five of which . are zoological. The work 'is dilpofcd according to the fyf- tem of Linnxiis, with (liort eflential generic and fpccific charafters copied from that author, and references to a few of the bea ligiiresof each fp.-cies. EngH(h, Scottidi, and Erfe names are fubioiiicd, with the general or particular paces of growth, duration, &e.; and the account of every plant rimHics with a longer or fliorter defcription in Enghfii, various botanical remarks, and compiled notes of its eco- Bomical or medical ufes.— The plan and the execution of this work appear calculated to render it one of the moll popular I'loras. it has found its way to the continent, u hero it is ge- nerally quoted, efpecially for the Cryptogamous clafs, which the author fays " cod more time and attention than all the ■other 23 claffes together." Yet we hare heard that this pub- lication did not, ior a long time at lead, pay its expences. This cer:ainly did not arife'from any want of merit ; for its only great and radical fault was not known, or at leaft fcarcely confidered fuch, till lately. Of this notice is taken under the botanical article Fi.OHA. The fault we mean is the compihng defcriptions from foreign authors, without mentioning whence they are taken; fo that a Undent -can never be certain of their jn(l application, but, on the con- trary, often finds them erroneous or unfuitable, without knowing why. Even in the lafl clafs, on which Mr. Light- toot bellowed fo much pains, the fynonyins of Linnasus and Dilleniiis often difa,;n-e, thougli in many cafes fuch con- trarietics are properly indicated, fo aj to throw original light on the fubjedi. Mr. Eightfoot was for fome years a fellow of the Royal Society, and was one of the original fellows of the Linna-an Society, the formation of which he contemplated with great pleafure, though his dpath happened before he could attend any of i"s public nieetinjjs. Having married the daughter of an opulent miller at Uxbridge, he refided in that town, and died there fuddenly in the fpring of 178S, agi d 53, leaving a widow and feveral daughters. He was buried in Cowley church, where his grave remained, for fome time at ieafl, without any memorial. He is fuppofed never to have j-ecovered from a dilappoinlment, relpcding a living, which L I G his patron, the late duke of Portland, folicited from lord chancellor Thurlow, but which the latter did not think fit to bellow. The fubjcft of our memoir had, in the courfe of his bo- tanical (Indies, coUeftcd an excellent BritiPi herbarium, con- fiding of abundant fpecimens, generally gathered wild, and in many cafes hnportant for the illullralion of his work. He had alfo amaffed, from fir Jofeph liaiikg and other friends, a number of exotic plants. The whole w as bought, after his death, for 100 guineas, by his majefty, as a pi'efent to the queen, and depoiitcd at Frogmore, the price being fixed by an intelligent friend of the family. The fpecimens having been for fome time neglected, were, after a while, dii- covered to be much infefted with iufcCts ; and as their royal poded'or, having a genuine and ardent tade for the fludy of botany, was anxious for their prefervation, the writer of the prclent article was requeded to give his advice ai^d alfdlance on this fubjcct. This led to his frequent invitation as a vifitor at Frogmore, and to a regular courfe of conveifations, rather than leflures, on botany and /oology, which her ma- jcdy.and the priiicedes Angudaand Elizabeth honoured with their diligent attention ; the queen regularly taking notes of every ledfure, which flic read over aloud at its conclulion, to prevent millake. 'J'he plan of this exemplary mother, on which flie has often been heard to defcant, was, in the edu- cation of her royal offspring, to open as many refourccs to them as polfible, in a variety of iludics and purfuits ; out of which they niight fubfequently make their own choice, and thus be independent of circumllanccs for occupation and amufement. Nor has the herbarium of Lightfoot been con- figned to uftlefs repofe. It was allowed to be confulted fre- quently, on the fubjedi of ScottKli Willows, and other doubtful matters, while the Flurn Brilanmca was preparing ; and the prefent blfhop of Carhfle was permitted to make all requi- fite ufe of it, for the completion of his valuable paper 011 Britifh Caricei, printed in the fecond volume of the Linna?an Society's Tranfac\iona. In the knowledge of thefe two ge- nera of plants, Mr. Lightfoot excelled mod botanllls of his day ; but the ipecimens of Linnsbs, being compared with his, have brought errors to light, which were never fuf- pofted before.

LIGHTNING, in Phyfn^ogy, is a large bright flame, darting fwiftly tlirough the air, and extending every way to a confiderable dillance, of inomentary duration, and commonly attended with thunder. Some have accounted for tliis phenomenon bv fuppofing, that, from the particles of ful- plnir, nitre, and other combuftible matter, which are ex- iialed from the earth, and carried into the higher regions of the atmofphcre, is form.ed an inflammable fubitancc, which, when a fufiicient quantity of fiery particles is feparated from the vapour buoyed up into the air, with thefe particles adhering to them by the coUifion of two clouds or other. ■wife, takes fire, and flioots out into a train of light, larger or lefs, according to the ilrength and quantity of the mate- rials. 0;hers have cxjiained lightning by the fermentation of fulphureous iubilances with nitrous acid? : fee Thunder. But in the prefent advanced .'late of the icience of tleftri- Vol.. XXL city, this i.s univerfally allowed to be iin eledrical phenom". non. Philofopiicrs had not proce-dcd far in their experi- ments and inquiries on thi.s iubjeft, before they were ilruck with the obvious anaiogy between lightning and eieftricitv, and they produced many arguments, a priori, to afcertain tiicir fimilarity. I'mt the method of verifying this hypo- tliefis was firlt propofcd by Dr. Franklin, who, towards the clofc of the year 1749, conceived the practicability of drawing lightning from the clouds: having fo.ind, bv prc\ii;i:s experim.cnts, that the electric fluid is attradtcd bv points, \\c. apprehended, that lightning might hkewife pollefs the fame- property ; though the.cffi cts of the latter muft, in an afto- iiilhing degree, fur])ars thofe of the forrrer. The other circuniftancts of refemblance between lightning and elec- tricity remarked by this ingenious pliilofopher, and abun- dantly confirmed by later difcovenes, are ti.e following: flafhcs of lightning, lie obferved, are generally feen crooked and waving in the air ; and the eleftric fpark drawn from an irregular body at fome diilance, and wlien it is dr.iwn bv" an irregular body, or through a fpace in which the l>eft con- duftors are difpoltd iu an irregular manner, always exhibits the fame appearance. Lightning llnkes the h'ghcll; and moft poiufcd ob;cas \\ its way, preferable to others, as high hiOs, trees,' fpires, mails of fliips, &c. and all pointed conduclors receive and throw off the eled'tric fluid more readily than thofe which are terminated by flat furfaces. Lightning is obferved to take the readiell and beil condiiclor ; and this is tlie cafe with electricity in the difcharge of the Leyden phial ; v hence the dodor infers, that in avhurdcr llorin, it would be fafcr to have one's clothes wet than dry. Lightning burns, dif- folves metals, (fee Fu.siON,'! rends fome bodies, has been often known to flrike people blind, dcllroys anim.Tl life, dcpi;ive$ magnets of tlKi:- virtue, and reverfes their poles ; and tiiefe are well-known properties of eleclricitv. Lightning not only gives polarity to the magnetic needle, but to all bodies that have any thing of iron in them, as brick, &c. ; ami by obferving v.-hicii. way the poles of thefe bodies lie, it may be known, witli the utmoll certainty, in what diredlion the flroke jiaded. Kignior licccaria fuppules, that pcrfons are fometimes killed by l-ghtning, witiiottt beinti- really touclicd by it ; a vacuum t)f air only being fuddenfy made near them, and the air rnfiiing out of their lungs to fupply it ; and with fo much violence that they could never recover their breath. In proof of this opinion he alleges, that the lungs of fuch perfons are found flaccid ; whereas, when they are properly kihed by the eledrical fhock, the lungs are found inflated : but this hypothelis is controverted by Dr. Priellley. In order to denionilrate the identity of the eleflric fluid with the matter of lightning, by r.clual' ex- periment. Dr. Franklin contrived to br'hig lightnincr from the heavens, by means of an eleclric kite, whtcii lie railed, when a florm of thunder was perceived to be coming on ; and with the eledricity thus obtained, he charged phials, kindled fpirits, and performed all other electrical experir ments, which are ufually exhibited by an excited globe or tube. This happened in .lune, 1752, a month after the eleftricians in France, of v.-hom the moil aftive were MefTrs. Dalibard and Delor, followed bv Mr. Mazeas and M. Mon- nier, purfuing tlie method which he had propofid, had verified the fame theory ; but witiiout any knowledo-e of what they had done. In April and .lune, 1755, In: dif- covered that the air wss fometimes eledrificd politivelv, and fometimes negatively ; and found that tlie clouds would change from pofilive to negative electricity feveral times in the courfe of one thuiuler-guil. He foon perceived that this important difcovery was capable of being applied to practical C nlc. LIGHTNING. ofe, and propofcJ a method, whicli he oon accomplilhcd, of fecuring buildings from being damaged by liglitniii^, by means of conduftors. The Enghfli philofophers had no: been lefs attentive to this fiibjcft than their neighbours on the continent ; but for want of proper opportunities for trying the nccefTary experiments, and from fome incidental circumdances that were unfavourable, they had failed of fuccefs. However, in July, 1752, Mr. Canton fucceeded ; and in the following month, Mr. Wilfon and Dr. Bevis ob- ferved nearly the fame appearances which Mr. Canton had obferved before. Mr. Canton alfo foon after obfervcd, in a number of experiments, that fome clouds were in a pofitive and fome in a negative ftate of eleClricity ; and that the elec- tricity of his conduftor would fometimes change f.'om one ftate to the other, five or fix times in lefs than half an hour. This variable llnte of thunder clouds was difcovered by S. Beccaria, before he heard of its having been obfervcd by Dr. Franklin, or any other perfon : and he has given a very exaft and circumftantial account of the external apj)earances of thefe clouds. From his obfervations of the lightning abroad, and of his apparatus within doors, he inferred, that the quantity of cleflric matter, in an ufual ftorm of thunder, is almofl: inconceivably great, confidering how many pointed bodies, as trees, fpires, &c. are perpetually drawuig it olf, and what a prodigious quantity is repeatedly difcharged to or from the earth. This quantity is fo great, that he thinks it impofiible for any cloud or number of clouds to contain it all, fo as either to difcharge or receive it. Befides, he ob- ferves, that, during the progrefs and increafe of the (lorm, though the lightning frequently ftruck to the earth, the fame clouds were the next moment ready to make a ftill greater difcharge, and his apparatus continued to be as much affccled as ever ; and, therefore, the clouds mull ha%'e received at one place, in the fame moment when a difcharge was made from them in another t and, upon the whole, he infers, that the clouds ferve as co- duClors to convey the eleftric fluid from thofe places of the earth that are overloaded with it, to thofe which are exhaufted of it. This eleclric matter, the rife of which, from the earth into the higher regions of the atmofphere, is afcertained by the great quantities of fand, aflies, and other light fubftances, carried up with it, and fcattered uniformly over a large tra& of country, wherever it iffues, attracts to it, and bears up with it the wat(*ry par- ticles that are difperfed in the atmofphere. It afcends into the higher regions of the atmofphere, being folicited by the lefs refinance it finds there than in- the common mafs of the earth, which, at thefe times, is generally very dry, and confequently highly eledlric. The fame caufe which firll raifed a cloud, from vapours difperfed in the atmofphere, drawe to it thofe that are already formed, and continues to form new ones, till the whole coUefted mafs extends fo far as to reach a part of the earth where tliere is a deficiency of the qlectric fluid. Thither, too, will thofe clouds, replete with elctlricity, be llronjjly attraAed, and there will the elediric matter difcharge itfclf upon the earth : a channel of communication being m this manner formed, a frefli fupply of electric matter will be raifed from the overloaded part, and will continue to be conveyed by the medium of the clouds, till the equilibrium of the fluid between the two places of the earth be rellored. When the clouds are at- tracted in their paflage by thofe parts of the earth, where there is a deficiency of the fluid, thofe detached fragments are formed, and a'fo thofe uniform defcending protuberances, which are, in fome cafes, the caufe of Water-fpouts and Hur- rkanes ; which fee. That the eletlric matter, which forms and animates the thunder-clouds, ilTues from places far beiow the furface of 2 the earth, and that it buries itfclf there, is probable fronr the deep holes that liave, in many places, been made by lightning ; and from the flaflies that have been feen to arife from fubterraneous cavitias and from wells ; as well as from the inundations accompanying thunder-llorms, and occa- fioned by water buriling out of the bowels of the earth. The greatell difficulty attending this theory of the origin of thunder-ltorms relates to the collection and infulation of eletlric matter within the body of the earth. With refpeft to the former, this ingenious philofopher has nothing to fay : fome -operations in nature are certainly attended with a iofs of the equilibrium in the_ elcflric fluid, but no perfon has yet afiigned a ir.ore probiible caufe of the r(>dundancy of the eleftric matter, which, in faft, often abounds in the c'otids, than what we may fuppofe poflible to take place in the bowels of the earth : and fuppofing the lufs of tiie eqi'.i- librium poflible, the fame caufe that produced the cft'ecl would prevent' the relloriiig of it ; fo that r.ot being able to force a way, at lead one fufTiciently ready, through ths body of the earth, it would ifl^ue at the fame convenient vent into the higher regions of the air, as the better paflage. 3. Beccaria oblerves, that a wind always blows from tlia place from which the thunder-cloud proceeds ; and it is cer- tain, that the fuddeii congregation of fuch a prodigious quantity of vapours muft dilplace the air, and repel it on all fides. A great number cf obfervations rclati.ig to the de- fcent of lightning, confirm his theory of the manner of its afcent : for, in many cafes, it throws before it the parts of condufting bodies, a::d diftribntcs them along the refilling medium, through which it muil force its paifage. Upon this principle, the longed flaflies of lightning feem to be made, by its forcing into its v.-ay part of the vapours in the air. One of the principal reafons wliy thofe flalhe.'i make fo long a rumbling, is their being occafioned by the vail length of a vacuum, made by the paffage of the eleftric matter. For although the air coUapfes the moment after it has pafled^ and the vitjra'ion, on which the found depends, commences at the fame moment ; yet, if the flafh was diretfted towards the perfon who hears the report, the vibrations excited at the nearer end of the track will reach his car much fooner than thofe excited at the more remote end ; and the found will, without any rcpercuflion or echo, continue till all tlie vibrations have fucceffively reached him. Mr. Lullin, in order to account for the prqduflion of eledricity in the clouds, made a long infulated pole to projedt from one fide of the Alps, and obferved, that when fmad clouds of va- pour, raifed by the heat of the fun, rofe near the foot of the mountain, and afcended along the fide of it : if they touched the extremity of the pole only, it was eleftrilied j but if the whole pole, and confequently part of the hill on which it flood, was likewife involved, it was not elcftrified. Whence he concludes, that the elcflricity of the clouds is produced by their paiTfng through the air while the fun ihines upo.i them. But to whicii of thefe two circumltances, namely, the motion through the air cr the action of the fun's rays, this was ov.ing, he could not dctern.ine, though he made leveral experiments for this purpofe. Upon liie whole, it is e, fy 'o conceive, that when pjrti- cula- clouds or different parts of the ear;h pofllfs oppofite eledlricities, fome being electrified pofi ively, and others negatively, a dilcharga .vill take place within a certain dif- tance ; or the one wi'l itrike into the other, and in the dif- charge a flafli of lightning will be obfervcd. But how the clouds or earth acquire this Hate, is lliil a qiicdion not ab- folntely determined. Mr Canton queries, whether the clouds become pofleffed of electricity b)' the gradual heating and cooling of the air ; and whether air fuddenly rarcf ed, SSMf LIGHTNING.- tnay tiot give ele'cirie fire to, and air fuddenly condenfed re- ceive e^ecTtr-c fire from, clo'.ids and vapours pafling through it. Mr. Wilcke fiippofcs the air to contract its electricity, in the fatne manner as fulphur and other fubllances do, when thev are heated and cooled in contaft with various bodies. Thus the air, being heated or cooled in the neighbourhood of the earth, gives eleftricrty to the earth, or takes it from it ; and the electrified air, being conveyed upv.'ards by va- rious means, communicates its eleftricity to the clouds. Others have queried, whether, fince thunder generally hap- pens in a fiiltry ftate of the air, when it feems repleniflied with feme fulphureous vapours, the eleftric matter then in the clouds may not be generated by the fermentation of fulphureous vapours with mineral or acid vapours in the air. Dr. Franklin advifes perfons who are apprehenfive of danger from ligiitninj, to fit in the middle of a room, pro- vided it be not under a metal luflre fufpended by a chain, fitting on one chair, and laying their feet on another. It is ftill fafer, he fays, to bring two or three m'-tralfes, or teds, in''o the middle of the room., and folding them double, to place the chairs upon them, for as they are not fo good conductors as the wall, the lightning wiU not choofe to pafs through them : but the fafell place of all is in a hammock hung with filken cords, at an equal diftance from all the fides of a room.

Its great friability is particularly charafterillic of at. Its furface is always cracked, and its mafl'es divide with the greateil facility into a number of cubic fragments ; a cliaracif r which is not found in jet. Friable lignite is more abundant and confequeitly more ufeful than the two firil varieties. It is found in horizontal banks often thick and extenfive, but is never feeu in fuch large maffes as coal, with which it has been confounded by fome ; it differs not only by its properties but alfo by its gcogiioflic li;uation.

Commonly called earth of Cologne, and fometimes^ though improperly, umber ; but the true umber, whicli comes from Italy or the eaft, contains nothing that is combulLble,. whence it cannot belong to this fpecies. This fubllanee is black, or blackifh-brown mixed witk- reddifh. Its fratlure and afpect are earthy ; it is fine- grained, eafily frangible and even irial-le; it is rather foft to- the feel. Its fpecific gravity is nearly that of water. It burns, emitting a difagreeable fmell. It not only often contains vegetable remains, but fome- times it.Gflf preients the texture of wood, without ever pof- feffing either the colour and luftre, or the hardnels of the pr-ceding varieties. It burns fufficiently well to be ufed as fuel. It gives a gentle and equal heat. It is found in fecondary formation in the neighbourhood of coal mines, and more frequently in alluvial land. As an authentic example of this variety may be mentioned the earthy lignite from the vichiity of Cologne, known ia trade by the name of eai'th ot Cologne. It is dug up at a little diilance from that city, near the villages Briihl and Liblar, where it forms very extenfive beds of eight or ten yards in thicknefs, v/hich are fituated under elevated ground. It is immediately covered with a bed, more or lels thick, of rolled pieces of quartz and jafper, of the fize of an eg.g, and refts on a bed of white clay of an unknown thickntls. The bed of lisjnite is homog-eneous, but foffil veiretables are found in it in a good Hate ot prelervation ; they arc, 1, trunks of trees lying one on the other without order; the wood is black or reddiih, generally comprefied', it readily exfoliates by drying in the open air. Some of theie belong to dicotyledonous trees, others are fragments of palms. Among thefe M. Coquebert-Montbret has found fome that are fi.led with a number of fmall round pyritic badies re- fembling grains of fmall (hot. Similar fmall, but elongated- round grains, refembhng a two-celled pod, have been found- by Mr. Heim, in the lignite of Kalten Nordheim. This wood burns very well, and even with a fmall flame.., 2. Woody fruits, of the fize of a nut, and which are con- fulered as belonging to a fpecies of areca. The hgnite of Cologne contains about twenty per cent, of a(hes rather alka- line and ferruginous. Its uies are manifold ;. it is wxirked in open air with a iimple fpade, but in ordei- to convey it wiih greater convenience, it is moillened and moulded iti veffcls which give it the fhape of a truncated cone. It is generally ufed as fuel in the neighbourhood of Cologne., v It burns (lowly but readily and wiihout flame, like fungu* tinder, giving a llroug heat and leaving very fine allies. The latter being conliuiicd as a very good manure, a paix L I G L I G •f the lignite is burnt on the fpot where it is wrought, for the fake of obtaiiiiiit^ them. The earth of Cologne is particularly employed for paint- ing in diftemper and even in oil painting.

This lignite is faid to occur alfo in Hcffia, Bohemia, Saxony, Iceland, &.c. ; but as there has been a confufion between this fiibdance and the variety of ochre called umber, we cannol be cert-,(in that thefe indications of localities are referable to earthy lignite. It may liave been obfervcd, from what has been faid on the fituations peculiar to fome varieties of lignite, that this foflil combuftible belongs to depofitions of the mod recent formation, fince it is found only in alluvial fand or clay ; it feldom or never occurs in (tony depofitions, except in coarfe grained lime-done and under brfalt. In the moun- tains of Hcffia called- the Ringe Kuhie, feveral thick beds of lignite are feen leiling on fandllone, and leparated by beds of potters' clay and fand. — (Mohs). On the fea-fliore near Calais, fragments of lignite have been found that were penetrated by very tranfpai'ent globularly aggregated quartz cryftals. The air which circulates where lignite is wrought is gene- rally bad. From what has been faid it appears (our author concludes) that lignite is of a very different formation from that of coal ; indeed, Mr Voigt thinks that there is no tranfition between thefe two fub (lances. The firft of Brongniart's varieties of li.'nite, is by Wer- ner given as a fub-fpeoies of his fclnvartz ko'n.le, or black coal. A variety not mentioned in the above account of ligi.itc, but nearly related to the tibrous lignite No. 3, is the fub-fpecies of Werner's brown-coal, called common bro'um-coal. Its colour is light ijrowiiifh-black, pafiing into blackifli-brown. It occurs maffive. Its fragments are indeterminately angular, more or lefs (harp-edged. It is found at Bovey, and feveral other places mentioned under tiie localities of (ibrous lignite or bituminous wood.

Garcias tells us of the wonderful elfefts of this xlrug againd the bites of venomous f.rpents, and defcribcs two kinds of the plant which produces it ; one having leaves like the pomegranate, and the other like the peach-tree : thefe, he fays, both grow in the iflar.d of Ceylon ; and Acofta mentions two other fpecies of plants producing this wood, both different from cither of thofe defcribcd by Garcias, and both grow- ing in Malabar.

It appears, upon the wht>le, that little can be depended on in the accounts of the medicine called lignum colnbrinum by any author, nnlefs he has himfelf experimented what he relates, and defcribed the plant which produces the drug ; for much imaginary virtue has been at all times given to many things againd the bitings of fcrpents, and the lignum colubrinum of one author is not the lignum colubrinum of another.

This powerful nation was compofed of many tribes, the boundaries of whofe fettlements cannot now be afcertained witli precilion. Thefe tribes were the Vediantii, who inhabited a mountainous traft watered by the Varus, in which were Nica:a or Nice, and Ceraenelium, or Cimia ; the Intemelii, who occupied feveral places along the fea-coait, ■viz. Intemelium, or Ventimiglia, Tropjea Augulii, or Torbia, &c.; the Ingauni, whole capital was Albingaunum, or Albenga, and they alfo occupied the fea-port towns of Vada Sabatia, or Vai, and Savo, now Savona ; the Epan- terii, who inh;;bited a mountainous diftrift between the Van- gieiini and Ingauni ; the Vangienni, who relided near the declivity of Mons Vefiilus, mount Vifo, and the fources of the Po ; the Statielli, who were cantoned at the bottom of the gulf of Genoa, in a hiily territory, that extended north- ward to the Tanarus ; the cities and towns in this diilriA, occupied by the Statielli, and other inferior tribes of the Ijigures, were Genua or Genoa, Portus .jDelphinus, or Porto Fino, Segeftra or Selhi, Portus Veneris, or Porto Venere, and Luna ; and the principal rivers of this dillritt were the Macra and Boactes ; the inland towns in the terri- tory of the Statielli were Aquas Statiella: or Aqui, Ceba or Ceva, near the fource of the Tanarus, PoUentia, Alba Pompeia, Afta or Aili, Bodincomngus or Induftria on the P", Forum Fulvii, furnamed Valentinum, on the Po, Ca- riftum, Dertona or Tortona, and Iria or Voghiera. The Celelates and Cerdicates inhabited an inconfiderable dillrift between the Trebia and tlie Po, now called Pavefan ; their principal towns were Clallidium, Chiailezo, and Litubium. The Briniates occupied a hilly traCl not far from the fea- coaft, watered by the Bosftes. The chief town of the Apuani was Apua, now Pontremoli, at the foot cf the Apennines, near the fource of the Macra. The Ananes, or Anamani were for fome time eftabiilhed in the territory now called Parma and Modena ; the Lingoncs, in tlie northern part of Bolognefe, and in Ferrara ; the Boii, in the S. part of the Bolognefe, at the foot of the Apennines ; the Se- rones, in the eftate of the church, along the coaft of the Adriatic from Rimini to Ancona. To thofe tribes belonged the following towns, "u/z. Parma, Bnxellum or Berfello, Forum Novum or Fornovo, S.W. of Parma on tlie Tarus or Taro, Tanetum or Tanedo, between Parma and Modena, Calicarin, S. of the Po, Padinum or Buondena, N V/. of Forum Alieni, now Ferrara, Hadrianum or Ariano, Neronia above the mouth of the Po, and Spina at the mouth of the fouth branch of the Po. The following towns were fituated on Via iEmilia, between Parma and /-^rminiuin, -jia. Tanetum already mentioned, Regium Lepidi or Reggio, Mutina or Modena, Bononia now Bologna, Claterna or Claterva, New Quadenio, Forum Cornelii or Imola, Favcntia or Faenza, L I G Forum Livii or Forli, Forum Popilii or Forlimpopoli. The inland fettlements were Sufemontium, Aquinum, and Ra- venna. LIGURIA, a country of ancient Italy, which had on the W. a part of the Maritime Alps, and the river Varus ; on the N. the Po ; on the E. a part of Gallia Cifpadana, and a fn-.all portion of Etruria. In the time of Scylax, who wrote about the year 350 B.C., the Ligurians extended themfelves to tlie Arnus. See the preceding article. LIGURIAN Republic. See Geno.i. LIGURINUS, in Ornithology, a name ufed by many- authors tor the bird more commonly known by the name of Jpinus, and called in England xhefi/hn. LIGURIUS, in Jciu'ijh Antiquity, a precious (lone on the high piriell's breall -plate. It is called lejchnn in Hebrew. Theophrailus and Pliny defcribe the ligurius to be a llone like a carbuncle, of a brightncfs fparkling like (ire. The ligurius was the firit; ilone in the third row upon the high priell's pedioral, and the name of God was infcribed upon it. iElian, De Animal, lib. iv. cap. 17.

L1GU.STICUM Leviflicum, or Comm'.n Lovage, in the Ma- teria Meelica. The odour of this plant is very ilrong, and peculiarly ungrateful ; its tafte is warm and aromatic. It abounds with a yellowifli, gummy, refinous juice, very much refembling Opoponax. Its virtues are fuppofed to be fimi- lar to thofe of angelica and mafter-wort in expelling flatu- lencies, exciting fweat, and opening obftrudions ; and it is therefore chiefly ufed in hyfterical diforders and in uterine obftrudions. A teacup-ful of the juice with Rhenifh wine, or a decodlion of the feeds with wine or mugw'ort water, was, by Foreftus, faid to be a fecret remedy cf extraordinary efficacy in flow or laborious parturition. Tiie leaves, eaten as ialad, are accounted emmenagogiie. The root, iefs un- grateful than the leaves, is faid to poflefs fimilar virtues, and may be employed in powder. Woodv. Med. Bot.

The leaves much larger, ending in acute points, of a brighter green, and continue till llicy are thrull oft by the young leaves in the fpring : the liowers are rather larger, and are not often fuccecded by berries in this climate. Method of Culture. — Thefe different plants are capable of being increafcd by fseds, layers, fuckers,aiid cuttings; but the firlf method aft'ords the bed plants : the feeds fliould be fowa in autumn, in a bed of common earth an inch deep, or in drills , the fame deptli ; but as they do not always grow freely the firll year, they may be buried till next autumn, in pots of fandy earth, in tlie ground, and then fown as above : when r!ie plants come up they fliould be kept well weeded, and, when a year or two old, be planted out in nurfery rows, to remain two or three years, then removed where they are wanted to remain : the layers fhould be laid down, from fome ot the pliable young branches, in tiie earth, in autumn or winter, when they will be rooted by the autumn fol- lowing ; then take tiiein off from the ftool, with their roots, and plant them in the nurfery for a year or two, or till of a proper fize tor the pnrpofes they are intended : the fucker* which arife annually from the roots fliunld be taken up in autumn, winter, or fpring, with roots, and planted in the nurfery as above ; the cuttings of the young Iboots, eight or ten inches long, fhould be pl.inted in the autumn, in a Hiady border, where they will be properly rooted by the following autumn, when they may be p anted out in nurfery rows, to acquire proper growth, in the manner directed above. The varieties with itriped leaves may be increafcd by budding, or inarching upon the pl.iin fort, or by laying do.vn tlie branches ; but they feldom flioot fo fail as . to produce branches proper for this purpofe ; and being more tender, they fliould have a dry loil and a warm fituation : in a rich foil . they foon lofe their varieg ition, and become plain. I'te ItaUan or evergreen fort, which is now ge:;er;.l!y fiiund in the nurferies, is equally hardy with the otljer fortSj and. thrives in almoit any fituation : it is incrcafed in the fanK; manner ; but as it feldom produces berries in this climate, they mull be procured trom the pLise of its- native. growth. Th;fe plants may be introduced in the fhrubberics antl other parts- by way of variety, efpecially the evergreen fort. But the chief ufe o^ the common fort is to form fuch hedges as are required in dividing gardens tor (belter or or- nament ; yet the Italian or evergreen kind (hould be pre- ferred ; it bears clij.-ping well, is not liable to be disfigured by infetls, and liaving only fibrou;) roots, it robs the grouwl lefs than almoll any other flirub ; it is one of the few plants that will thrive in the fmoke of large towns, though it fel- dom produces any flowers in th- clofer parts after the firll year : it alfo grows well under the drip of trees and in, fhade j the fphinx ligullri, or privet hawk moth, and phalena fyrin- garia, feed on it in the caterpillar (late, and nicloc vcficato- rius, cantharides or blifler beetle, is found on it. From the pulp cf the, bwries a rafe-coloured pigment may be pr«- 2 pared ; L I L L I L pared ; with which, by the addition of alum, wool and filk may be dyed of a good durable green : for which purpofe they mull be gathered as foon as they are ripe.

So much was he now regarded by the people as a champion of liberty, that a remonftrance, ligncd by many tluuifand names, was preientcd to the houfe of commons in his behalf. This failing of effeft, he continued to publilli pamplilets, in which he dif- played his grievances in fuch bold and virulent language, that he rendered tlie leading men of all parties his enemies. It (hould, however, be obferved, that the leading men al- luded to, were thofe who were either adherents to the king, cr thofe who were attached to Cromwell ; but Lilburne, perceiving that both parties were hoflile to the liberties of the fubjeC'l, did not fcruple to oppofe all their projects, which he fufpefted, and juilly too, would lead to the cda- blilhmcnt of a tyraimy in (ome fliape or other. He charged Cromwell with a delign of ufurping the fovereignty ; and accufed him and his relation Ireton of high treafon, for ■which h-.; was ordered to be tried as a libeller. At this period he had fo many friends among the people, that the houfe ot commons judged it proper to difchargo him from prilon, and make an order for remunerating him for his fuf- f^rings. At the time of the king's death, Lilburjie was bufy in plans for fetth»:g a new model of government. Finding the leaders of the army refolved to keep the power in theiv own hands, he oppofed them with his ulual ir.tre- pij'.iy, and maintained the right of the people to form a conftitution for themfelves. So dangerous now did he ap- pear to Cromwell and his council, that he was again com- mitted to the Tower, and was brought to his trial for high treaion before a fpccial couunillion. On this occafion he defended himlelf witli great firmncfs, never once (liewing a difpofition to crouch to his profecutors or his judges : he felt that he Hood on firm ground, and was determined not to bend to the circumllances of the times. The trial laftcd many hours, and when the jury were about to retire to con- fider their verditl, the foreman aflov, from xfiuvr;, duf!, or pollen, be- caufe the flowers feem in general to be fprinkled with a powdery fubllance, from the abundance of their pollen.

LILLO, George, in Biography, an Englifh writer of tragedies, born in London in the year 169^, was the fon of a Dutch jeweller, by an Enghfli mother. He was brought up to his father's trade, and carried on the bu- finefs with great reputation for feveral years. His firll publication, as a literary character, was entitled " Sylvia, a haliad-opera ;" but his fame is founded on his tragedies, which are rcprefentations of domeftic dillrefs in common Hfe, exhibited for a moral purpofe. By the choice and ma- nagement of his Horses, he f\icceeded in rendering them eminently pathetic, and he difplayed no inconfiderable of fome fortune, he fpent much time in frequenting fermons, leftures, 5;c. and became attached to the Puritan party. In 1632 he ftudied aftrology under a perfon named Evans, a profligate clergyman, who, on account of certain immora- lities, was obliged to quit a curacy. Lilly in a few weeks obtained of his mafter all the requifite knowledge of his art, and in a fnort time excelled him in calculation. The firil fpecimen which he gave the public of his flcill in aftrology, was an intimation, that the king had chofen an unlucky ho- rofcope for his coronation in Scotland. About the year 1634 he got poffeffion of a book in MS. entitled " Ars notoria," teaching the pretended occult fciences, from wluch he eagerly imbibed tlie doclrine of the magic cir- cle, and the invocation of fpirits, which he praftifed fer fome time, ufmg certain prayers prefcribed in it, addrcfled to angels whom it reprefents to be inftruftors of men ii\ thele grand arcana. Previoufly to this, few perfons, who knowledge of the human heart. His tragedies are " George praftifed in the aitrological art, pretended to go farther Barnwell,"' "Fatal Curiofity," and " Arden of Fever- than to endeavour to trace out and recover ftolen goods ; (ham." The firil of thefe is, we believe, uniformly brought but Lilly treated this part of the myftery with great on the ftage about Chriftmas in every year, and it generally contempt, and laid claim to the fupernatural fight, and brings crowded houfes : the play entitled " Fatal Curiofity" the gift of predicting future events, which he well knew is mentioned by the late James Harris, efq. in his " Philo- how to turn to his own advantage. In i6'6 he fettled logical Inquiries,'" as a fine example of the gradual unfold- at Her/ham, near Walton on Thames, in Surrey, where be- ing of a" fcene of horror, not lefs perfeft than that which remained till 164 1, when he came to London, with a num-- has been fo long and highly applauded in the (Edipus of ber of curious books, in his ov.-n art, which he had pur- Sophocles. Attempts have been made to revive its reputa- chafed in the country. In 1644, he pubbdied his " Mer- tion, but without fuccefs. The "Arden of Fevertham" linus Anglicus," an almanac, which he continued annually was a pofthumous piece. His other performances have till his death, and feveral other works which were written long fince been forgotten. He died in 1739, at the age of on the fubjefts of his art ; devoting his pen and other la- 47, and his works were collected and edited in 2 vols. 8vo, hours fometimes to the king's pavtv, and fometimes to that by Mr. Davies, v.-ith a thort account of his hfe ; to wliich of the parliament ; raifing his forfjne by favourable pre- the reader is referred for farther particulars.

In 1648 and 1649, he read public lectures on aftrology, for the improvement, as he pretended, of young (Indents in the art, and managed matters fo well, and profitably, that in 1651 and 1652, he laid out nearly 2000/. in an eitate at Herlham. During the fiege of Col- cheiter, he and Booker, another aftrologer, who was alfo a licenfer of mathematical books, were fent thither to encou- rage the fcldiers, which they did, by aifuring them that the town wouldfoon be taken, which proved true in the event. In the year 1 650, having predicted in his almanac that the parliamentary gevernment would be overturned, he was lummoned to anfwer for his conduft, but during the inter- val of four-and-twenty hours, which were allowed him, he got the obnoxious leaves reprinted, and carried before the 28 miles E.S.E; of Toledo LiLLO, a fortrefs of Brabant, on the E. fide of the Scheldt, built bv the Dutch in 1584, and ever fince gar- rifbned.

On tlic reftoration of Cliarlcs II. he was examined as to the perfon who decapi- tated the late kinj,s and declared that it was cornet Joyce. On account of the part which it was known he hid taken during the commonwealth, he was glad to fue out a pardon under the great feal, which was granted him. In i66j, when the plague raged in London, he removed to Herfliam. After the great fire of London in 1666, he was examined as to the perpetrators of the deed, but he was unable by his art to fatisfy his employers. Shortly after this he adopted for a fon a perfon named Henry Coley, a taylor by trade, and gave him the profits of his almanac.

It was the princij)al fortrefs of the Carthaginians in Sicily, and ih.e only city that refilled Pyrrhus wiien he paffed into this ifland in the 47 ^th year of Rome ; but having been ineffeftually befic-ged for five years, it was ceded to the Romans after the victory of Lutatius, A. U. C. 511. The ifle Tligadcs, the modern Maretimo, which is oppofite to Marfala, feenis to be the key of that immcofe harbour. It is formed by rocks, little low iflands, tongues of land, and fand-banks, which break the waves on all fides, and form a large femi-circle, within which the fea is always calm. It was from this fort that the formidable fleet commanded by Scipio Africanus failed, when he let out for Afiica in the fecond Punic war, A.U.C.548. The beauty of this harbour induced the Saracens to call it " Marfala," fignifying, in their language, tl e " Port of God." The number of inhabitants at Marfala is clUmated at a^jOoo. Of this famous port and impregnable city, the traces that remain are fome few ruins of the ancient walls W. of the town, built with enormous mafles of llone, whicii no machine, before the invention of cannon, could fliake. In front of thefe wall.s were deep ditches, hewn out of the rock, fome parts of which ftill exilt. Here is no longer any anchorage for fliipping, and the port is only fit for the reception of fited Rome, and attended tlie ledures of the moit celebrated fmall barks. It was dellroyed, as it is faid, by Don John profeifors. He now returned to London, and opened a fchool for the learned languages, rhetoric, and poetry, which he taught on pure clalhcal principles. In 15 10, when dean Collet founded St. Paul's fchool, he app;)inted Lily the firft mailer, a ftatiou which he occupied v.'ith An- gular utility for twelve years. He died of the plague in 1.J22, or 1523. Lily was much elleemed by his contempo- raries, as well for his moral cliaradler, as for his literary abilities. He was the author of feveral Latin poems and tracls, but is bell known for the grammar that goes under his name, and is llill ulcd in our public fchools.

The arcl.bllhopric of Lima comprehends 15 jurifdiclions, w'a. the circuit of Lima, Chan- cay, Santa, Canta, Canete, lea, Pifco, and Naica, which three places form one jurildiilion, Guarachia, Guanuco, Yauyos, Caxatambo, Sarma, Jouxa, Canchucos, Guyalas, and Guamalies. The diocefe of Truxdlo contains fevea jurifdiclions; that of Guamanga nine; that of Cuzco fourteen ; and that of Arequipa fix. Lima, a famous city of the audience of Lima, and capital of the vice-royalty of Peru. This city, called " Civdad de- los Reye?," or the city of the kings, from its having been left likewife a MS. life of bifliop Filher, which is depofited founded by Don Francifco Pizarro, on the read of the Epi- in the library of the Royal Society. Biog. Brit. phany, A. D. 1 5^3 ;, is fituated in the fpacious and de- LlLY-, \n Botany. SceLlLlCM. ' lightlul valley of Rimac, whence, by corruption, the name Lily, in Gurj/i-mn^, the common name of this well known Lima is derived: Rimac being the ap'^ellation of an idol flower plant. See Amauxlus, and Lilil'M. to wliicb the. native Indians ufed to offer facrificcs, as the Yiica* LIMA. Yncas alfo did, after they had extended their empire hither : and as it was fuppofed to return an anfwcr to the prayers ad- drefled to it, they called it, by way of diftinftion, Rimac, or lie who fpeaks. The fituation of this city is peculiarly advantageous, as it is placed in the centre of a valley, the ■whole of which it commands. Towards the north, at a confiderable diilance, is the Cordillera, or chain of the Andes ; whence fome hills project into the valley, the neareft of which, to tlie city, are tliofe of St. Chriftopher, and Amancaes. A river of the lame name walhes the walls of Lima, over which is an elegant and Ipacions (lone brido-e, with a gate of beautiful architedure, that forms the entrance into thcvcity, and leads to the grand fijuare, wliich is large, and finely ornamented. In the middle of it is a noble fountain of bronze, and fuch olijefts, uletul as well as orna- mental, are not uncommon. The form of the city is triangular, the bafe, or longed lide, extending along the banks of the river. Its length is 1920 toifes, or -jds of a league; and its greateft breadth from N. to S., that is, from the bridge to the angle oppofite to the bafe, is 1080 toifes, or |ths of a league. It is fnrrounded with a brick, •wall, fianked with 34 baftions ; and in its whole circum- ft-rence it has feven gates and three poiterns. On the fide of the river oppofite to the city is a fuburb, called St. La- zaro, which has lately increafed ; all its flreets, like thofe of the city, are broad, parallel, and at right angles, forming fquare? of houfes ; all well-paved, fupphed from the river ■with ftreams of water, arched over, fo that they contribute to cleanunefs and falubrity, without the leaft iiiconveniency. The number of ilreets is faid to be 35 j, and of houfes 3941 . Towards the E. and W. parts of the city, within the walls, are many fruit and kitchen-gardens ; and mod of the prin- cipal houfes have gardens for amufemcnt, which are conti- jiually refrelhed with water by means of canalj. The whole , city is divided into five parilhes, and abounds with churches, convents, nunneries, colleges, and charitable foundations, which it would be tedious to recount, and it has alfo a famous univerfity, founded in 1576. All the churches and chapels are large, and adorned with paintings -and other decorations of great value. The viceroys of Peru ufually refide at Liima, enjoying all the privileges of rpyalty, and, befides afhlling at the courts of jullice, and the councils relating both to the finances and war, give every day public audience to all forts of perfons ; for which purpofe, there are in the palace three very grand and fpacious rooms. Under the •viceroy there is a number of officers, and of tribunals for the tranfaAions of the bufinefs of the city and audience. The Cabildo, or Ayuntamiento, that is, the municipal body of the city, enjoys particular privileges ; and the re- venue of the capital exceeds 36,000 dollars. Since 1786, tliere is alfo a judge of the police, afilfted by an able archi- teft, and other officers. Upon the whole, we may obferve, without reciting par- ticulars, that Lima is not only large, magnificent, and dillin- guilhed as the capital of the kingdom, by the refidence of the viceroy, and the fuperior courts and offices, but that it has an acknowledged fuperioijity over the other cities in that part of the world, from the inftitutions that are eftablilhed for the advancement of literature and the fciences. It is a place v.'here lu.Kury prevails to a great degree ; the malls are crowded with bandfome carriages ; the number of coaches and calafh'cu being computed at 1400. Never- thelels, amufements are rare, and literature is negleded. Little encouragement is given to publications of a kind moft likely to mtereil the inhabitants of the city and its environs. The univerfity of St. Mark is condufted on the plan of tlie Spanifh univerfitie*. The theatre is » neat building ; but the exhibitions do not difplay much tarte. Coffee-houfcs only began to be opened in 177 1. Cock- fighting is a favnurife amufement on Sundays and feflivals ; nor are bull-fightr, unknown. The number of inhabitants in this city, according to the lateft enumeration, amounts to ^2,627 ; the monks and clergy being 1392; the nuns 1585; the Spaniards, in general, 17,215; with 3219 Indians, and 8960 negroes, the reft being Meftizos, and perfons of other calls. The rich ecclefiaftics, proprietors of entailed eilatcs, mih'tarv and civil officers, and phyiicians, advocates, attornies, and artizans, may amount to 19,000 ; the reft being ilaves or domeftics. The want of occupation leads many of the females to vice ; and the men are rather inclined to indolence and floth. The population has declined finre the ereftion of the new vice-royally of La Plata ; and it is likely ftiil farther to dccreafe, notwithllanding an i iflux of 1400 perfons of all fexes and conditions, who annually arrive aa a fupply ; not to mention the Spanifh j^irls, who, from the province of Pinra in the north, and lea in the fouth, come hither to difpofe of their charms either in mar- riage or love, thofe provinces being celebrated for female beauty. All the inhabitants of Lima, from the highcft to the loweft, are fond of fine clothes, and they indulge their pafiion to great excefs. The women's drefs confiils of a pair of ftioes, a chemife, a petticoat of dimity, an open pet- ticoat, and a jacket, which, in fummer, is of linen, and in winter of ftuff, to v.hich fome add a mantelette. Women ' of the loweft condition, whofe whole ftock of apparel confifti merely of two chemifes and a petticoat, wear bracelets, rofa- rifs, and finall gold images, about their necks andarms, to the valne of fifty or fixty crowns. The females are, in general, of a middling ftature, handfome, genteel, of a very fair com. plexion, withbeautitul hair, and enchanting luilre, anddiTnity in their eyes. They are naturaUy gay, fprightly, jocofe, with- out levity, and remarkably fond of niufic. The temperature of the air at Lima is agreeable ; and though the difference of the four feafons is perceptible, they are all moderate, and none of them troublefome. Spring begins towards the clofe of the year, ;. e. towards the end of November, or beginning of December ; this is fucceeded by fummer, the heat of which is moderated by the fouth winds : at the latter end of June, or beginning of July, the winter begins, and con- tinues till November or December, the autumn intervenino-. As rain is feldom or never feen at Lima, the place is equally free from tempefts, and tiie inhabitants are totally firangers to thunder and lightning: there are, however, orhcr incon- veniences and evils 10 which they are obnoxious. In fum- mer they are tormented with fleas, bugs, and raofquiloes ; ' but the moft dreadful calamity to wliich this country is fubjetl is the recurrence of earthquakes, of which they have had feveral, which have almoft ruined the city. Thefe have occurred in 1582, 1586, 1609: 1630, 1655, 167S, J687, 1696, 1697, 1699, 1716, 1725, 1732, 1734, '745' and 1746 ; the latter being the moft tremendous and deilruftivs. As the beft fecurity againft carthouakes, they build their houfes moftly of \*ood, and the walls of wattled oziers or canes, covered with clay, and painted. The dillempers moft common at Lima are malign;uit, intermittent, and catar. lious fevers, pleurifies, and conilipations ; and thcfe rage covitinually in the city. The fniall-pox is slfo known here ; and when it occurs proves fatal to many. The wealth of this city is chiefly derived from the mines in the province* to the north and fouth-; but agriculture profpers very much in the vicinity, and the" fii Ids fupply food for a multitude of Iiorfes and cattie. The fertility of the foil was very much improved iii ancient times bv the care of ilje Yocas, ta cut L I M L I U and arrange trenches in fuch a manner, as to condmSt the water of the rivers to irrigate the foil j and when the Spaniards took pofTcfTion of the country, they purfued the fmie phin ; thus they watered the fpacioua fields of wheat and barley, large meadows, plantations of fugar caaes, and olive trees, vineyards, and gardens of all kinds, which were rendered very produAivc. By the eartliquake in 1O87, the foil was fo vitiated, that it hecame unfit for yielding wheat and barley ; but after remaining 40 years in this (late of fterility, it again fo far recovered itfelf as in a confiderablc degree to become fit for grain as before. Hoivever, re- peated earthquakes have been unfavourable. Tlie fields in the neighbourhood of Lima are chiefly fovvn with clover, of which there is a very great confuniption, as it is the com- mon fodder for all beads, particularly mules and horfes, of which there is an inconceivable number. The bread at Lima is the bed in all this part of America, both with re- gard to its colour and talle. The mutton and beef are alfo very good ; and here is alfo plenty of poultry, pork, and fifh ; which latter article is fuppliod by the Indians of the coalt, from the bay of Callao, and the villages of CheriUo and Luria. The river of Lima, and the coafts, furnifli anchovies and various forts of {liell-tifli. The wines at Lima arc of diflerent forts, white, red, and dark-red, and of each fort fome are peculiarly excellent. ■ They are imported from the coalls of Nafea, Pifco, Lucumba, and Chili, but the latter produces the beft. That from Pifco has the greatell fale, and from the fame place all the brandies ufed at Lima or exported are brought. Many of the dried fruits are brought from Chili, and by the trade carried on between the two kingdoms, Lima is fnpplied with all lorts of fruits known in Spain. At Lima tliere are no fabrics nor manu- fadlures of any kind. Lima owes much of its magnificence and fplendour to its being the capital of Peru, and the general ftaple of the kingdom. As it is the relidence of the government and chief tribunals, it is alfo the common factory for commerce of every kind, and the centre of the produces and niannfaiflures of the other provinces, together ■with tliofe of Europe, brouglit over in the galleons or regif- tcr tbips ; and dillributed from hence through the wide (rxteut of thefe kinj;doms. At the head of the commerce is the tribunal del Confulado, which appoint commiflaries to retide in the other cities of its dependencies, extending through all Peru. The chief commerce of Lima is with Valparaifo, Concepcion, and Coquimbo, in the kingdom of Chili ; the ille of Chiloe, and Arica, Ilo, and Pifco in the fouth i towards the north with Truxillo, Pacafmayo, and Payta, in the viceroyalty of Peru ; with Guayaquil and Pa- nama in the viceri>yalty of New Granada ; and with Realejo in Giiatamala, and Acapulco, in Mexico. This trade is conducted by 10 (hips, 11 merchant-frigates, 19 packet- boats, and a balandra, »r fmall Irar.fport-boat ; amounting in all to 351,500 quintals of tonnage, navigated by 460 feamen. After the dedru&ion of the fea-port town of Callao by an earthquake in 1747 (fee Callao), a new town or village was fou ded, at the didancc of a quarter of a league, called " Ballavilla." There is a fortrefs called " San Fernando," with a fufBcient garrifon to defend the bav, which in the S.W. is fenced by a barren idand called " San Lorenzo." Here all the fliips anchor about two leagues from Lima. The coalls of Nafca and Pifco fend to Lima wine, brandy, raifins, o ives, and oil ; and the king- dom of Chili, wheat, flour, lard, leather, cordage, wines, dried fruits, and fome gold. Every Monday, during the whole year, there is a fair at Callao, whither the traders or proprietors of commodities refort from all parts ; and the goods are carried, according to the dircclioiis of the buyers. on droves of mules kept for tliis purpofe by the mafterS of the warehoufes. Copper and tin in bars are brought frdm Coquimbo ; from the mountains dc Caxamarea and Chaca-' poyas, canvas made of cotton for fails and other duffs of that kind, and Cordovan leather and foap are made all over Valles, the valley in which Lima is fituated. From the fouthern provinces, as Plata, Oruio, Potofi, and Cuzco, is fent Vicuna wool, for making hats and fome ilulTs of a peculiar firinnefs. From Paraguay, the herb called by that name is fent, of which there is a great cojifumptiorf. The produce of the fales in the inland parts of the king- dom is fent to Lima in bars of filver, and pignas, which are porous and light mades of iilver, being an amalgam of mercury and dull taken out of the mines. The Jilver is coined at the mint in this city. I^ima has alfo its particular trade with the kingdoms both of N'Tth and South America. The mod conliderable commodity received from the former is fnud", which is brought from the Havannali to Mt xico, and after havinjj been there improved is forwarded to Lima, and conveyed from thence to the other proviices Thero is no province in Peru, that does not tranfmit to Lima its products and manufatlures ; and fupply illelf from hence with the neceflary commodities. Lima alfo receives from the ports of New Spain, paph» tha, tar, iron, and fome indigo for dyeing. 'Phe kingdom of Terra Firma fends to Lima, kaf-tobacco and pearls, which fuid here a good market, as no mulatto woman is without fome ornament made of them. The ladies and women of all ranks have an ancient cudom of carrying in their mouths a " linipion," or cleanfer, of tobacco. The intention of thefe is, as their name imports, to keep the teeth clean. The limpions are fmall rolls of tobacco, four inches long and nine_ lines in diameter, tied with a thread which they untwift as the limpion wades. One end of this they put into the mouth, and alter chewing it for fome time, rub the tCLth with it, thus keeping them always clean and white. All the timber nfed in building houfes, refitting (hips, or condrnfting fmall barks at Callao, is brought from Guayaquil, together with the cacao. S. lat. 12' 2' 31". E. long. 282 27'.

This genus, of which there are fifteen fpecies mentioned in the Syftema Naturae, comprehends thofe animals that are commonly known by the name of flugs, or naked fnails, which commit fuch depredations in our fields and gardens, efpecially in wet weather. Of the fifteen fpecies Jix arc common in our own country. Species. I^rvrs. Body black, and almoil wilhoutvvrinkles. It is fbund among mofs late in the autumn, and is about half an inch long. The body is glofly, with undulate tranfverfe ftricE on the {hield ; narrov%-Er, and not fo much wrinkled as the aler, which is the next mentioned. Ater, or black (lug ; body black and furrowed with ikep wrinkles. Of this fpecies five varieties are enumerated : 3'. The colour of this is deep black and pale beneath. 2. Bliiok, with a pale greeniih ridge down the back. 3. Black, beneath white; mouth yeUowiih. 4. Chefnut-brown, be- neath white; mouth yellowifh. J. Dudcy-brown, with a yel- h.iwiih n.O'jth and llreak each fide. This laft is common in woods, meadows, fields, and gardens ; and is from an inch and a half to five inches in length ; it crawls vciy flowly, ;i»d leaves a flime upon whatever it paffes over ; feelers al- ways black ; the back is convex ; the fliield rough, with numerous dors ; abdomen wrinkled. Albus. This fpecies, which is characterized by the white- r.efs of its body, contains four varieties. I. llie entirely white. 2. White edged with yellow. ^. White, with an orange margin and hmd-head. 4. White, with black feelers ; it inhabits woods and groves, and is from a quarter to half an inch in length. RuFUs. Body, above pale rufous, beneath while; it inhabits fliady damp places, and the botloin of hills, is L I M about an inch and a half long; the body has neither ^cts nci* belts; its feelers are larger than thofe of the ater. Flavu.s. Body am.bcr-colour fpotted with white, and is found in herbage. Maximus. Body cinereous, with or withoat fpots ; there are fix varieties, ijiz. 1. Body immaculate; (hield black-blue. 2. Shield fpotted with black ; body with black longitudinal ftripes. 3. Shield and body fpotted with black. 4. Body with five whitifh llreaks, the lower one interrupted. 5. Body with white and cinereous wrinkles, and black fputs in a double row. 6. Bodir edged with v.'hite ; inhabits woods, gardens, and damp cel- lars ; is from four to five inches long. Hyalinus, takes itsj name from the colour of its body,- which has a hyaline or glafly appearance ; feelers obfolete;,- with a brown line reaching from the feelers to the fliield ; this is found in damp molfy places, and is very deilructive to the young fhoots of kidney-beans; belly with numerous- interrupted wrinkles. Agre.st!s. Ruftic fliig; body whitifh, with black- feelers ; this fpecies is divided into four varieties, of which the I, is entirely whitifh, immaculate; 2, whitifli, with a yellowifli fiiield ; 3, whitifh, with a black head ; 4, whitifh, with a cinereous back; 5, whitifli, with fcattercd black- fpecks. The mofl curious of the above varieties is the fecond, that with a yellowifh Ihield, or that which is characterized by Miiller, in his Hill. Verm. " Limax albidus clypeo flavefcente," or by Gmelin, " Limax albus, clypeo flavef- cente ;" it has been figured by Liller, but more accurately, and with great care, in the fourth volume of the Linnxan Tranfadfions, in which it is exhibited in a ftate of repole, • as it is feen in its progrefTive motion on the ground ; and alfo as it is obferved fufpended from the branch of a tree,. &c. both with refpect to its upper and nnder furfaces. . This variety is denominated in our own language the /pin- ■ ^''"'S.f^"S' ^'"^ ^^ commonly about three quarters of an iucll^ long ; it inhabits woods and other fhady places. It vrzs particularly noticed by Mr. Hoy, and defcribed in the ilrft volume of the Tranfactions of the Linn-Tan Society ; at firlt he faw it ful'pended from the branch of a fir tree, and was not aware that it was a living creature. It was hanging by a fingle line or thread attached to its tail. This thread was in the upper part extremely fine, bnt near the animal it be- • cam.e thicker and broader, till at length it exactly cor-- refponded with the tail. Its defccnt was at the rate of an ■ inch in three minutes, a motion fufficiently flow for the minutell obfcrvations. The line by which it defeended was drawn from the fiimy exudation gradually fecreted from ■ the pores that covered its whole body. .Apparently there was much exertion required to produce a fufficient kipply of the liquid, and to force it towards the tail ; it alter- nately drew back its head, and turned it as far as poffible, firfl to one fide, and then to the other, as if to prefs its fides, and thus promote fecretion. In addition to Mr. Hov's account, w« fhall give fome farther particulars, taken iiom a curious paper by Dr. John-' Latham, in the fourth volume of the Linnsran TranfacTtiuns; a work that contains abundance of interelting matter, but which is too expenfive to liave a ver}' general circulation be- yond the members of the focicty. .Speaking of the curious property belonging to the fpinning flng, the-dtjclor fays, " that it is a cullom not unuiual for this fpecies of hniax: to pafs from an height fecurcly to the ground, by means of a thread of its own coultiudion feems manifeft ; for, on my friend's (Colonel Montague, F.L.S.) putting one of them on. the projecting frame of a w indow, it jwiuediatcly crawled forward* L I M L I M forwards till it Ctme to the projefting anglf, from wlitnce, without attariptiiig to fix itfelf by its fore parts to any tiling, it became viiibly fiifpcndcd hy a thread from its tail. 'When it had dt.'fcendod two feet, the colonel took it up by the thread, and carried it to a dillant room ; but trying to fix it afrefli, in order more accurately to obferve its profrrefs, the tliread broke. He chcn put it on a frame about four feet from the gronnd ; in a few minutes it was again fuf- pended, and obferving by his watch, it defccndcd at the rate of th'-cc inches and a half in a minute." After re- peated trials, tlie colonel, by means of glafTes, was enabled to afcertain that the fecretion, of which the thread was formed, \»a.s wliolly from the under parts, and not from the back and lides, both of which appeared nearly dry, nor did it proceed from any orifice in the tail. This creature .feemj quite feiiiible of its abilities, for it extended itfelf from the bottom of the frame, with its head downwards, till the tail became fufpended ; and it was by means of an undulating motion of die belly that the flow of the vifcous fecretion was produced towards the tail, but in doing this the belly was contracted, being furnidied with numerons tranfverrc rvgtc ; at the fame time the body and tcntacula were fully extended, indicating no alarm whatever ; the head was occafionally moved from fide to^fide, which gave ieveral turns to the right or left, as the centre of gravity lay ; but as it as frequently turned one way as the other, the thread was not in the leall twilled. The thread, on firil leaving the tail, was five times as broad as it wa? at the eighth of an inch diftant therefrom, but afterwards feemed of an equal fize, and confiderably fmaller than the fineft human hair. When a portion of this thread was placed under a microfcope, it appeared contrafted ; it was pel- lucid and elallic. By anotlicr writer on this fubjeft we are told, that by the application of the microfcope, the flimy humour will be feen to come out infcnfibly from the jjlandnlar pore« of the flvin, like clear and minute points ; thele, by continuing a gentie prefTure on the flcin, will be- come fmall drops, and in the end form a confidcrable col- ledion of matter. It may be alfo obfcrvcd, that colonel Montague found feveral individuals of this variety that he could not induce to fpin, and, as if fenfiblc of their inability fo to do, readily turned back when approaching the pro- jected edge ; while others at once let themfelves down without hefitation ; fo that it might be known by their motion, when near the brink of the precipice, whether they were endued with the facuhy or not. After thefe ani- mals have fpun for i'omc time, their fpinning power fecnis to be for a while loll, but in all thofc on which experiments ihave been made, it has been recovered again by keeping them for a few hourr, among wet mols. The fifth variety above-mentioned, or that with fcattered black fpecks, is found in gardens, paltures, and groves, from May till the end of the year, and is the animal which has been recommended to be fwallowcd by confumptive perfons. It is about half an inch in length, and when touched it ilicks to the fingers as if dead. CiNxrcs.

Anciently, it was as much the duty of the fnrgeon to provide his patient witli a wooden leg after am- putation, as to cut off the member, which endangered life and could not be prefcrvcd. At prelent, however, the bufinefs of furnilhing artificial limbs is left almoil entirely to the mechanic, though it cannot be denied, that the atten- tion of a judicious furgeon will often be well befiowcd in taking care, that the preffure of fiieh machines is contrived to fall as little as puitible upon that part of a f*ump which is moll tender, stid inclined to ulcerate. The end of a thigh- Ihimp, indeed, can ill bear the cflecls of preflure, and in this cafe, it is ufual to mr.ke the thigh part of the wooden member in the form of a conical box, which is calculated to receive the flump, and at the fame time not allow the end of the bone to meet with any material refinance below. The preffure partly falls on the fides of the remaining por- tion of the thigh, and partly on the pelvis, round which a flrap proceeds from the upper part of the machine. The makers of artificial limbs in this metropolis, however, have in general brought their bufinefs to great perftction, and fuch patients as can afford it, may be accommodated with contrivances, which, v.'ithout being heavy and cumberfome, bear a great refcmblance to tiie natural limb. Artificial hands and arms may alfo be procured, which have moveable fingers, and by the ingenuity of the nicchanifm, may be made to perform many little uleful offices in grafping and holding things.

LIMBORCH, Vnihiv,m Biography, a celebrated Dutch divine, was born at Amllerdam m the year 163^. He was educated among the Remonfirants, and had lor his inltruClors among others, Barleins, and Gerard Voffius. Having com- pleted the ufual courfes of learning, in ethics, philofophy, and the languages, he ftudied theology under Curcellsus, the fuc- ceifor of Epifcopius, in the profen'orfiiip of that facult)-, among the Rcmonllrants at Amlterdam. Aftervvards he went to Utrecht, where be attended the lefturcs of Gilbert Voetitis, and other celebrated divines. In 1654 he undertook the c;fjice of minilter at Haerlem, from whence lie removed to Gouda. In 1660 he pubhfhcd an excellent colleftion of the correfpondence of learned and celebrated men, under the title of " Epiftola; pra:ft.antium, et eruditorum virorum," 8vo. In 16^4 and 1704 he puhliflied new editions of it, greatly cnhirg-ed, in folio. In tliis coUcftion, almolt the en- tire hifl:ory of the affairs of the Remonftrants maybe traced from the time of Arrainius down to the fynod of Dort. In 1G61 he pubiilhed, in the form of a dialogue, a ircatife in defence ot toleration, which was excecdinfjly well received by the friends of lilierty. In 1667 he undertook the paf- toral charge of the church at Amllerdam, and in the foU lowing year he was appointed divinity profeflbr. From this period he wholly devoted his iludies to the enquiries con- netled with his new office, and acquired a high reputation by the manner in which he pertornied :13 duties. In the year 1686 he publiflied his fyllem of theology, under the title of " Theologia Chrilliana ad Praxim Pietatis ac Pro- molioncm Pacis Chrillianae unice direcla." It pafled very quickly throKgh four editions. In this fame year Limborch had a difpute with Orobio, a Spanifli .Tew, who had efcaped from the prifon of the Inquifition, and foon after he publifhed the fubftance of it in a treatifc, entitled " Collatio Arnica de Veritate Religionis Chriftianz, cum eruaito Judso." This treatife very iatisfattorily repels the objeftions which any confillent believer in the 'Old Teltament can advance againll the New. He obtained, in 1692, "The Buok of Sentences ot tlie Inquifition of Tholoufe from IJ07 to 13 13," which he pubhflied, and prefixed to it a hiltory of that horrible and bloody tribunal drawn from the writings of the inquihtors themfelves. The title of it is " Hilloria In- quilitionis ; cui fubjungitur Liber fententiarum Inquilitionie Tholofanae, ab anno 1307 ad 13 13, "410. This hiftorj- is pronounced, by Mr. Locke, to be a work abfolutely perfect in its kind ; it was tranflated by Dr. Samuel Chandler into Englilh, in two volumes 4to. with additions by the editor, by Antlwny Collins, efq. and by the author. Dr. Chandler prefixed to his edition an introduftion, concerning the rife and progrefs of perfccution. In 1694 he converted a young woman to Chriitianity who had been drawn over to the .Tewifli religion by a perfon of whom (he had learned the Hebrew language. In 171 i Limborch publiflied his va- luable " Commentarius in Adta Apottoiorum et in Epillolas ad Romanos, et ad Hebr-jsos." He died in the month of April 1 7 1 2, in the feventy-ninth year of his age. A funeral oration was delivered on the occafion by Lc Clerc, who, among other tilings, fays, *' He was, above all thi: gs, ani- mated with the love of truth, and was indefatigable in fearching for it, day and night, in the facred fcriptures and th-,' beft expofitors, and whenever he found it, he adhered to it inflexibly. His piety was pure and ardent, uiitinftured by lupenfition, or any notions diflionourable to the benevo- lence of the Deity. As a preacher he was methccical, argu- mentative, and iulid rather than eloquent ; and fo invariably was he governed by candour, moderation, and prudence, that he never gave offence to any one. In his inltrudtions front his prof^effional chair, he was diltinguiflied by the greatell perfpicuity, and the moft exaft order ; to which iiis memory', which retained whatever he had written, no doubt greatly contributed. His behaviour towards ail who had the hap- pinefs of being acquainted with him, was fo affable, kind, and conciliating, that they faw him with delight, and re- gretted, when they could no longer enjoy his converfation."

It affords good arable ground, and abounds with a fine breed of cattle. Near the town of iinibourg are found mines of iron, lead, and calamine, LlMBOUllO, late capital of the above-mentioned duchy, now a town of France, in the department of the Ourte, and chief place of a canton, in the diftridl of Malmcdy ; fituated near the river Wa/.e, in a fertile country, on a pleafant mountain. It was formerly fortified in a regular mauRcr, and had a caiUe, built on a rock, and defended by towers andbaftions, conllrufted of free- (lone. Wheii it was ceded to the houfe of Auilria by the treaty of Baden, the fortifi- cations were dellroyed.

Among the nnmerous colours of common compaft lime- flone, the molt frequent are the various fhades of grey, fuch as fmokc-grty, vcllowilh-grey, bluifli-grey, rediifli and greenifh-grey ; it is alfo feen greyifh-white, greyifh-black, flefli-red, with fome deep tints of red and ot yellow ; fevc- ral of thefe colours often occur in the fame fragment, and moftly in fuch veined, clouded and other delineations which are dillinguiflied by the epithet of marbled. It is moftly found mallive, fometimes in rolled, feldom in tabular pieces, frequently with, and aiiuoil entirely com- pofed of, extraneous follils, particularly fliells. Internally it is dull. Its texture is always more or lefs clofely conipaft, fometimes wax-like ; fratture I'mall and fine fplintery pafTing into large and flat conchoidal, and fome- times into even. Fragments indeterminately angular, more or lefs fharp-edged. The varieties having a clofe texture are tranflucent on the edges. It is femi-hard, fometimes approaching to foft ; brittle; eafily frangible. Specific gravity from 2. ,00 to 2.700. It is chiefly compofed of lime, carbonic acid, and water ; but is feldom without an admixture of fome argil and oxyd of iron, and fometimes intlanuiiable matter. This widely extended fubllance occurs principally as fletz rock, but it is alfo found in the tranfition mountains. The tranfition lime-llone is generally more tranflucent on the edges, and very often exhibits variegated colours, parti- cularly black, fnicke-grey, bluifli and greenilli-grey, and red. It contains,»like the fletz lime-llone, petrifaflions, but moft- ly of fea animals, the prototypes of which do no longer exift. With regard to the pctrifaf'lion, both in the tranfition and fletz lime-llone, it is to be obfervcd, that they occur pretty regularly difpofed ; difl'erent ftrata being generally furnilhed each with particular genera or even fpeeies. Fletz lime-llone occurs, almofl without exception, dif- tinttly flratified; the ftrata are fometimes very thin, of which we have a remarkable inilance in the lime-ftone quarries of Sollenhofen, near Pappenheim, in Germany. Tliefc ftrata, which, as Mohs inf'jrms us, arc very regular and perfcftly ho- rizontal, contain the well-known petrifactions which are called after that place, but are much leis frequently found than is generally imaeined. M. de Bournon fays, that in the Alpe of Dauphine lime- ftone is found in ftrata of no more than one or tv,o inches in thickncfs, in which cafe it is not unfrequemly mixed with quartz. This lime-ftone in tables, called laujcs in Dau- phine, is employed for enclofing fields : a fimilar variety is found at Grenoble at the foot of the mountains of Saf- fenages. Fletz lime-flone is frequently alternating with fubordinate ftrata of niarle, and bituminous marie flate ; but in thefe cafes the lime-ftone is generally greatly predominating. The ex- terior of mountains coinpofed of iletz lime-ftone is of a peculiar kind ; the hills formed by it are feldaim conical, but blunt and malTv, and interfetled by deep valhes. There are, befides the tranfitiuu lime-llone, fcveral other formations L I M E. formations of compaift lime-Hone. That called by Werner xhejirjljlctz, Ttms-Jhne is the oideil ; its lowell ftratuin is the bituminous and cupriferous marie flate, or tiie kupjir-fch'.ej'tr- fift^, as it is called by German miners : it extends round a CTreat part of the oldell mountains of Germany, fuch as the Hartz, the Thuringian foreil, Suabia, &c. rells on the old red fand-ftone, and is covered by the oldeft flet/. gypfum, or the variegated fand-flone.' It contains, bclldcs the above copper (late ftrata, feveral ores of copper, cobalt, heavy fpar, S:c. being the produdlions of veins. The fecond formation of fletz lime- Hone is calledyJ.-//- Tims-Jlom, on account of its abounding in petrifactions, which, however, are not peculiar to it, nor do tliey confill in (hells only, for the upper llrata contain likewife petrified crabs, vermiculites, fpecies of afterias, &c. (See Shells, peirified, and M.^rble. ) It is widely extended, and appears molb charafteriftic in Franconia, Suabia, and Bavaria. This formation is alfo remarkable, on account of the many caves which occir in it almoft in all parts of the world, and many of them filled with the oUeous remains of land animals. The moft famous of thefe lime-ftone caves are thofe of Muggendorf and Galenreuth in Cayreuth, at Eichitedt in Franconia, the Baumanlliole on the Hartz, thofe of Dal- matia, Carniola, Hungary, Siberia, &c. There are fome other fubordinate formations of fletz- lime-ftone ; which, however, require to be more clolely ex- amined before their charafters can be determined with any thing like precillnn. Of fuch apparently diftinft depo- fitions the following are mentioned by profeffor Janieion. I. A fletz lime-ftone, in Poland and_ Silefia, which alternates with beds of lead-glance and calamine. It was formerly called the calamine formation, and Karften confiders it as fubordinate to the firll fletz lime-ftone, but, according to Werner, it belongs to the fecond. 2. -V depofit of lime- ftone between Drefden and MeilTen, particularly near Plauen and in the vicinity of Gbttingen, which was confidered as a third fletz lime-ftone formation, but is now clafled as a mere variety of the fecond fletz lime-ftone : it is generally fandy, or mixed with clay, and is therefore feldom ufed as lime, but principally employed as a building ftone. It often eon- tains petrifactions, fuch as corallites, ammonites. Sec. and fometimes lead-glance is difteminated through it. 3. A lime-ftone formation at Wehrau, in Upper Lufatia, contain- i"g newer petrifaftions, fuch as peftinites, mytilites, S:c. : It alternates with beds of fand-ftone, and the whole refts upon alluvial land. 4. A fletz lime-ftone of a reddifli-brown colour, frequently containing petrifaftions ; it is horizon- frilly ilratiried, and contains beds of a variety of alum flate. Alfo a conchoidal lime-ftone of Greece is mentioned as pro- bably conftituting a particular formation. The ufes to which compacl lime-ftone is applied are various ; it is principally employed as a building ilone, and burnt for makir^g lime and mortar; nor is it lefs important to the agriculturift as a manure, to the miner as a flux for the reduction of ores, to the foap-boiler, tanner, &c. The iiiie-graincd and variegated varieties of compail lime- ftone, many of which are highly valued, are known by the name of marble ; a term which is more particularly applied to the fine varieties of granular lime-ftone, and alfo given to various mixtures of lime-ftone with other fubftances.

Frafture fine fplinlcry, a charafler not cafily obfervable, on account of the fmallnefs of the diftin£t concretions. Fragments indeterminately an- gular, blunt-edged. It confifts of fpherical, granular, diftinft concretions ; each of which is generally compofed of concentric lamellar concretions, which are either cemented together by a marley fubftance, or connected by limple contact ; the grains vary in fize, and are often fo minute as to be fcarccly diftinguifh- ableby the naked eye ; the largelt are nearly of the llze of a pea, but thele are feldom fcen. In fome. varieties each globule is an aggregate of fever. 1 fmaller globules. It is opaque, feldom tranflucent on the edges. It is foft and fcmi-hard ; brittle ; eafily frangible. Spe- cific gravity 2.456 — 2.494, Ku'w. Its chemical charafter is little diiTerent from that of the common corapaft lime-ftone. The variety analyfed by Kir- wan was compofed of 90 parts (jf carbonate of )ime and 10 of aluminc, with fome oxyd of iron. This fub-fpecies is much lefs frequently met with than common compaft lime ftone. It occurs, however, in con- fiderable quantities at Brunfwic, in Thuringia, particularly in the dittricl of Weimar, in that of Mansfeld, Sangerf- haulen, Klofterroda, &c. in Tyrol ; in Englar.d, at Bath, in Derby ftiire, at Purbeck. It occurs chiefly, in more or lefs confiderable beds, in the variegated fand-ftone forrrtition, to which it is fubordinate, and between the ftrata of \v-hich it is generally intcrpofed with great regularity. It contains no pelrifaftions, nor is it metalliferous. Roe-fto!ie, being very fubjeft to difintegraticn, is feldom employed for the purpolos of building ; but it is in fome countries ufed as a manure. The more compact varieties take a tolerably good polifli. The name of roe-ftone is given to this mineral on account of its clofe refemblance to hlb.-roes ; indeed, the old mine- ralogifts were fo far niifled by the imitative form of this fubftance, that they realK conlidcred it as the petrified roes of fifti. The origin of the ftruflure of roe-ftone is not«eafily ex- plained ; fome have confidered it as a conglomerate of rolled pieces of hme-ftone ; others have afligned the fame origin to It as to the pea-ftone ; but Werner confiders it as the refult of cryftallization. 2.

Its chief colour is white, often fnow-white, greyifli, yellovr- ifli, and greenifli and reddilli-vvhite ; alfo bluifli, greenifli, a(h and fmoke-grey, and greyiili-black ; from grcenilh-white it paftes into yellowifti and olive -green', and /rom reddifli-white into pearl-grey and .ftcflj-red. Its colours arc moftly uni- form, but it alfo occurs fometimes fpotted, and with llriped and veined delineations ; and on their rifts the mafl^es are now and then marked with dendritic figures. It is maflive. Internally it alternates from fliining to glirtening and glimmering ; its luftre being intermediate be- tween pearly and vitreous.

Pure white granu'ar hV.e-ilone is infufible before the blow- pipe, and only crumbles to piccef. In the charcoal cruci- ble, that of Carrara was found by Klaproth to be burnt to <|uicklime; while in the clay crucible it was fu fed into a compaft, tranfparent, hard glafs of a light glafs-green co- lour. It iifi'.ally ftrongly effervefces with nitric acid, and •when pure is foon difiblved in it without leaving a refidue. Granular lime-ftone is almoft alway.'! of primitive forma- tion ; it feldom occurs as tranfition rock, and fcarcely ever as a produftion of fLCOndary mouvitains, or if it be found in thcfe, it is never in extcnfive depofitions, but only in beds of rot very con uderable dimcnfion.s. As tranfilion rock it prin- cipally occurs on the Hartz ; it is found there of a grey colour, and of coarfe granular texture. Primitive granular lime-ttone is fcidom feen very diftinflly ftratified ; it moll commonly occurs in confiderablo beds in gr.eifs, mica flate, and clay flate, in which latter the Iran- fition lime-ilone appears, which, however, principally be- longs to compaft lime-tlcne. It is generally iimple, bi:t alfo font.iins ingredients which are characleriUic of it, fach as mica, quartz, ferpcntine, tremoiite, hornblende, c!ay (late, garnets, magnetic iron-ftone, blende. Sec.

Some varieiies of granular lime-ftone have manifcfted a confider^le decree of flexibility ; one of thefe was dif- covered by M- Fleuriau de Eellevne, at an elevation of 6000 leet, on Campo Longo, on mount Gothard. Tlie fame phe- nomenon may be anificially produced by expofing granular iime-ftone to a certain degree of heat. 3. Cakartous [par. Cak /par. Jam. Kalhfpath, Wern. Civr.monfiary Kirw. Spalh cakaire, Broch. Its principal colour is white, which is pure and fnow- ■whitc, or greyifli, yellowifh, greenidi, and feldom reddidi ; it occurs alio olive, afparagus, piilachio and leik-green ; greenidi-" rey, yellowifli-grey, honey, ochre, wine, ai^d wax- yellow ; flelh-red, brov.n-red, and very rarely rofe-red ; fmoke-grey pafTuig into black ; very feldom pearl-grey, and light violet-blue. It occurs mafiive and diffeminated, alfo drufcd and fta- laftiticil, but molt commonly cryftallized. The primitive figure of the cryftals is an obtufe rhomboid of 101' 32' 13", and 73- 27' 47", according to Haiiy ; and of TOl'^ 32', and 7S' 28', according to Bournon. The integrant molecule, as obferved by Monf. de Bour- ron, is a trihedral prifm with inclined bales. The number of modifications derived from the primitive rhomboid is very confiderable ; thofe enumerated in the laft mentioned author's very elaborate " Trait e de Miacr.dogie," amount- ing to no lefs than !ifty-nine. The figures fuppofed fundamental by Werner, and from which all the others may be derived, are : the fix-fidcd pyramid, the fix-fided prifm, and the three-fided prifm.- The followinir Wernrrian defcription of the different va- rieties of calcareous fpar is from JanVefon's Mineralogy. 1. The fixfi(hd Prifm. — When perfetl it is acute, and three alceruate lateral edges are more obtufe tiiaii the otheni. It occurs I. Simple; either erect or inverted. The inverted has three cylindrical concave, and three inwardly bent lateral plants, and on the upper extremity it is flatly acuminated by three planes, whicii are fet on the c)lindrically concave lateral planes. 2. Double, where the lateral planes of the one are obliquely fet on the lateral planes of the other, in fuch a manner, that the edges of the common bafis form a zigzag line, and the more obtufe lateral edges of the one are oppofed to the lefs obtufe lateral edges of the othci- pyrnmid. Of this figure the following varieties occur : (7. The extremity of the pyramid is fometimes more or lefs- deeply and flatly acuminated by three fomewhat convex planes, which are fet on the more obtufe lateral e the L I M E. 9 the fummits become ftill more acute, an acute double llirec- lided pyramid is formed, f. The acute double three-lidod pyramid is fometimes truncated on the lateral gdgcs, fome- times bevelled : in the latter cafe, when the bevelling planes become fo large that the original ones are very fmall, or even difappear, the refult is an acute double three-fided pyramid, having its planes length-v.ife divided ; or it is a double fix- fided pyramid, g. If the fummits of the double fix-fided pyramid are deeply truncated, it gives rife to the fix-fided table, having its terminal planes fet on alternately in oppo- lite dircAions. Though the preceding defcription of the different modi- fications of Calcareous fpar may poflefs the merit of fpeakin^ to the eye, yet it can by no means fuperfede the details of a llriclly cryilallographical inveftigation ; we therefore fub- join a fiiort abftraA of the excellent clafUlication given by coimt B nu-non.in the firll volume of his " Tratte de Mine- ralogie" lately publithed. All the modifications of cryftallized carbonate of lime are by this author divided into, i, prifmatic; 2, rhomboidal ; and J, pyramidal modifications. I. Prl malic Modifications. 1. Prifm from th: eigei of the hafc of the pr'tnuti-ve cryflal ; or thefe edges intercepted each by a plane. — Of this, a variety with very fnort prifm occurs in Cumberland and Uerbyfhire. That with long prifm ( Chaux carbon, prifme, Haiiv, pL 24. f. 10 ) is likewife found in Cumberland. The variety in which the lateral planes form rhombf, fo that the cryftal at firft fight has the appearance of the garnet dodecahedron, is the Icarceft of this modification. 2. Prifm from the fol'td angles of the lafe ; thefe angles of the primitive cryilalbcinginterccpredeachby a plane. — The chaux carb. ImitaLli, Haiiy, (ib. fig. 12.) belongs to this modification. It is generally feen in combination with others. Sometimes two of the planes of the pyramid of the primitifle rhomboid enlarge at the expence of the third ; and fometimes one of them caufes, in the fame manner, the two others to difappear. Found in Cumberland, Dauphine, and on the Hartz. 3. Summit intercepted by a plane perpendicular to the axis. — This modification feldom occurs in its finiple fiate. The varieties in which this plane is of confiderable extent is called chaux carb. liafee by Haiiy (pi. 23. fig. 8.) This is fre- quently feen nnited with the preceding modifications; in which cafe, if the new plane has caufed the j-'vramid of the rhomboid entirely to difappear, the chaux carb. prifmatique, Haiiy, (pi. 24. fig. 14.) is produced, the fineft groups of which are found in Cumberland and on the Hart/. Some of the lateral ])lanes of thefe prifnis frequently enlarge, at the expence of the adjoining planes; fo that one, two, or even three, entirely difappear. The cryflals of the regular hexahedral prifmatic variety, from the Hartz, are not unfre- quently feen with white opaque furface, and alfo fometimes to include fimilar cryflals of fmaller diameter, which now and then project above the terminal plane of the larger cryf- tal. The prifm of this variety is often fo fhort as to repre.- fent a thin fix-fided table. When both the fecond and the firil modifications are united in the prifm, we have the chaux carb. peridodicacdre of Haiiy (pi. 26. fig. 33.) II. Rkomloidal Modifications. A. Obtufe Rhomboids. Of thefe, Nos. 5, 6. 8, and 9, have not before been noticed. 4. Obtufe rhomboid of l\^° "LC)', and G^,\\'. — One of the moft common modifications, and more frequently than all the rell (except the preceding) combined with otjiec modifications.' It is produced by the edges of the pyranids of the primitive rhomboid being replaced each by a plane equally i-.iclining on thofe by which the edge itfelf is formed. In its complete ftate, tliis modification is the chaux carb. iquiaxe of H;iuy (pi. 23. fig. 2.), wiiich is much more fre- quently met with than the different pali'ages of the primitive rhomboid into this modification. The planes of this fourih modification are often longitudinally itriated ; and when they are arrived at tlieir limits, the llris run parallel to the fhorier diagonal of the rhomboidal planes This is found united principally with No. 2, reprefcnting various degrees of elongation of the chaux carb. dodkacdre, Haiiy (pi. 24. fig. j8.) : found alfo as twin cryftals in Derbythire ; with No. 1, belonging to the chaux carb. bifur.itaire, Haiiy (fig. 17.\ ch;tily from Cumberland (rare); with Nos. i and 2, and witn Nos. 2 and 3, chaux carb. tqui-vaknte, Haiiy (pi. 25'. fig. 28 ), both from Cumberland ; with Nos. 2 and 3, and part of the primitive planes, whence it is called chaux carb. Iriforme by Haiiy ifig. 26.). Tlie lall mentioned variety is from the Hartz ; and both the fpecimcn of Haiiy and that defcribed by M. de Bournon are remark- able, for having part of the pyramid covered with cryftalline matter, whicli appears to be depohted after the cryftal had been completed, and is thus forming a paflage into the regular hexahedral prifm. 5. Very obtufe rhomboid of \\y 56', and 6i' 4'. — It is produced by tlie edges of the primitive rhomboid being re- placed each by a plane, which is inclined towards its ium- mit. This has hitherto been found only in combination with other modifications, viz. Nos. 2 and 3. The cryflals are all from the Hartz, where red filver ore is fometimes accompanied with them. The variety of calcareous fpar, called en rofe, generally belongs to the complete rhomboid of this modification, as alio m.ofl of thofe known by the names of coxcomb and lenticular ip.ir; but they are feidom determinable by the goniometer. 6. Obtufe rhomboid 0/" 1 13 and G'f. — This is cafily con- founded with the preceding modification. Count Bournon has obferved it only in a few inllances, combined with the planes of Nos. i, 2, and 36 {vide infra), in cryflals from Derbyfliire and Cumberland. 7. Obtufe rhomboid of 107" 3', and 72" 57'. — This is the refult of a decrement of the lamina;, ilniilar to tljat which produces the preceding modification ; but the planes thus formed are more inchned on the bafe of the primitive rhom- boid. To this is to be referred Haiiy's chaux carb. guadri- rhomboidale. (Ann. du Muf. d'H. Nat. t. I. pi. 8. fig. 4.) It is always obferved in combination with other modifica- tions, fuch as with thofe of Nos. i, 2, and with thofe of the primitive cryllal. They come from Dauphine and Derbyfhire. Th.is modification has not yet been feen pet- feCl ; though nearly fo, in a variety which has very narrow planes of No. i . One variety from Derbyfhire, which has the prifm of No. 2 combined with this modification, and part of the planes of the primitive rhomboid, might be cafily miilaken for prifmatic rock cryllal, of which it has fome- times the tranfparency. 'J^he planes marked / in Haiiy's chaux carb. relrcgrade, (pL 26. fig. 36.) belong to this variety. 8. Very obtifs rhomboid of 118' 34', and 61' 26'. — This moll obtufe of a'l rhon;boids known to occur in calcareous fpar, is the refult of a decrement of the cryftalline lamina?, at the obtufe angles of the planes that form the fclid angle of the fummit, which is thus replaced by three planes refling on thofe of the primitive rhomboid. This modification, which is fcarce, does not occur in its complete ftate ; befides with planes of the primitive rhomboid, it has been obferved F z in L 1 M E. in i-ombination with thofc of Nos. I, 3, 5, 8, 41, and 43 j molt of them from the Hartz. Perhaps fome of the very flat lenticular varieties of calcareous fpar may be alfo referable to this modilication. q. Sligkly ohtuji rhomboid of 95° 2ft', and 84' 32'.— This very rare modilicHtion is produced by the obtufe anglrs on the bafe of the primitive rhomboid being replaced, each by a plane refting on the correfpondinir primitive planes. It is obvious, that the cleavage of this rhomboid mail be different from that of the hill mentioned modification, by being on the planes of the fiimmit inltcad of the bafe; while that of all the preceding rhsmboids, likewife at the bale, takes T)lace on tlie edges. This rhomboid has been obfervcd per- left in fpecimens from Siberia ; and in combination with the planes of No. 36. B. Acute rhomboiiU. Nos. lo, 12, 15, 16 and iS — 21 of this divilion are new. 10. ylcute rhomboid of 6 J' 28', and 1 14° 32' The obtufe angles of t'.ie primitive rhomboid replaced each by a plane, as in the preceding ; but being the refult of a more rapid decrement of the lamina:, its axis is three times longer than that of the primitive rhomboid. Occurs, though rarely, in Dcrbyfhire, both in its complete ilate, and in combination with remains of the planes of No. 2. 1 1 . ylcute rhomboid of 45 '' 34', and 134° 26'. - The refult of a decrement on the fame angles as in the preceding, but the decrement prodiking a rhomboid much more acute. It is the chaux carb. coiitrajiante of Haiiy (pi. 23. fig. 5.) one of the moll common rhomboids that occur in calcareous fpar. It occurs perfect, fomctimes with traces of the pri- mitive planes, and in combination with Nos. i, 2, 3, 4, and 36. Is found in Derbvlhire, Cumberland, at Grenoble in France, on the Hartz, &c. When the planes of the rhom- boid of this modification are combined with thofe of the common acute pyramidial dodecahedron, No. 36, they, re- place the folid angles of the bafe of this dodecahedron in the form of an elongated trapezoid. 12. Acute rhomboid of ^o'^ 36', and 139- 34'. — Decrement on the fame angles as in the preceding, to which it ap- proaches clofely. Occurs mollly in its complete ilate in Uerbylhire, and has been feen combined in the fame cryllal with planes of the primitive rhomboid, and Nos. i, 14, and 36, in which latter its planes are placed nearly in the fame manner as thofe of the rhomboid of the preceding modi- fication. 1 3. Very acute rhomboid of i j' and 165''. — Decrement on the fame angles as in the preceding modifications, but giving origin to a much more acute rhomboid. Count Bournon has obferved it in its complete Hate. It is feldom feen, and it is difficult to preferve it, on account of the great fragility of the fine termination of the cryllals. Combinations of the planes of this and No. 4 occur in Derbyfhire, on the Hartz, &c. and in Cumberland, generally on cryllals of fulphate of barytes ; the one called chaux carb. coniraSce (Haiiy, pi. 24. fig. 20.) belongs to it. Fine groups of this modification in its complete Hate have been found in Wcftmoreland ; and in the lame fpccimen, combined with planes of the very acute pyramidal dodecahedron, No. 54. 14 Slightly acute rhomboid of ?)■]' ^2' , and g2^ 18'. — This is the chaux carb. cuhdide of Hauy, (pi. 23. fig. 7.) It occurs complete, with planes of the primitive rhomboid, and combined with the planes of fevcral other modification'', fuch as Nos. 1 — 4, and No. 15, in Languedoc, at Stron- tian, Bi»th, in Derbylhire, and on the Hartz. This modifica- tion," combi:!ed with the planes of No. 3, is the chaux carb. apoph'ine oiWixx)-, (pi. 24. fig. 15.) 15. Acute rhomboid c/84" 26', and g^" 34'. — This rhom- boid, the preceding, and all the following, arc the refult of a decrement of the cryftalline laminae on the obtufe angles of the.bafc ; and the cleavage in all of them takes place at the fummit, and on the edges of the cryllal. Though combined with moll of the other modifications, the planes of this rhomboid have never been mentioned by cryllallo- graphers, a circumllance probably owing to their fmallncfs, and tlieir having been confounded with the preceding, from which it is, however, cafily dillinguilhed, even without the alfidance of the goniometer. It is fometimes found in a complete ftate on the Hartz, and at Strontian in groups, accompanied with ililbitc and crofs-ftonc, or harmoiomc, and in combination with the planes of Nos. i — j. and alfo with the remains of thofe of the primitive rhom.boid. 16. Acute rhomboid of Si^ 19', rtni-/ 98^ 41'. — This is oftcncr feen in its complete Ilate than combined witl; the planes of other modifications, fuch as thofe of Nos. i, 2, 3, 4, and 36 ; it alfo occurs with traces of the primitive rhomboid. Moll of thcfe were brought from the ifland of Ferroe, and from Scotland ; the former mollly in groups, with flilbite zeolite, the others with analcime zeolite. The variety in which it is combined with No. 4, came from Caf- tagna-moro, in Italy. Their gangue, in the above places, is a wacke like rock. 17. Acute rhomboid of y ^^ 31', and 104' 29'. — This is the chaux carb. invcrfe (Haviy, pi. 23. fig. 3.), fo called becauie this rhomboid is, as it were, an inverfion of the pri- mitive. Next to No. 14, it is the moll common of all the modifications of calcareous fpar ; but a circumllance worth remarking is, that it fcarcely ever occurs in any other but (liell liine-ftone ; while the reverfe prevails with regard to the primitive rhomboid which, in its pcrfcft Hate, is feldom found in any brt the older formations of lime-flone. The name of muriatique, given to this rhomboid by Ronre de I'Ifle, is derived from the juil mentioned mode of oc- curing. The complete rhomboid frequently occurs in veins at Bath, in Derbyfiiire, and lining hollows of (liell- marble in feveral other parts of Britain. In dill greater perfcftion it is found, together with various combinations of the phines of other modifications, in the (hell lime-ftone of Coulon, near Lyons, and in thofe ofVougy, near Roanne, in Forez ; in the former of thefe places it is generally feen in the interior of filiceo-calcareous geodes ; in the latter in geodes of black, earthy, and compacl black manganefe, with mammillary internal furface. It has been obferved by M. de Bournon combined with the planes of the primitive rhomboid, and with thofe of Nos. i to 4, and Ncs. 11, 14, 36, 37, and 49. That with narrow remains of the primitive planes is Haiiy 's chaux carb. an//a(V« (pi. 23. fig-9-)> '''^t with remains of the primitive planes, and ihofe of the prifm No. 2, has been defcribed by the fame cryflallograjiher under the name of chaux carb. uniiinaire (Ann. du iVIuf. Par, vol. i.) ; that w>lh the planes of the fame prifm No. 2, and with thofe of No. 3, is Haiiy's chaux carb. perfiflanta (pi. 25. fig. 29.) ; the fame with additional remains of the planes of No. 4, is his chaux carb. coardonnee ; and a variety in which this rhomboid is combined with narrow/ planci of Nos. 1, 2, 3, 4, and 37, is defcribed by hira. under the name of chaux carb. quadruplante. (An». du Muf. vol. i.) 1 8. Acute rhomboid of 70° 1 8', and IC9" 42'. — This rhom- boid is very rare, ana has been feen in combination only with the planes of the prifm No. 2, accornpanied by planes of Nos. 23, 30, 36, and of the primitive rhomboid. Thefe cryllals occur in Cum.berland and in Derbyfiiire. 19. Acute rhomboid of bl 12, a;«/iiS 48'. This has been obferved by count Bournon, in its complete Ilate, im 2 m-dfs LIME. mafs of brown iron-floiie ; and alfo in combination with the planes of the primitive rhomboid and tholL' of Nos. i, 2, 3, 4, 1 1, and 36. The cryllals exhibiting this modification are, with a few exceptions, ail from Derbylhire. 20. ylcuU rhomboid of ^y ^^', and 12^ 26'.— This rhom- boid, which has been obferved complete, and in combination remains of the primitive planes, and thofe of Nos. 2 and 3, is of ftill rarer occurrence than the preceding. Found in Derbylhire and Cumberland. The preceding, and the next modiiication, fometimcs exhibit, underneath"their pyramidal edges, the planes of the priinitive rhomboid, which, elpcciahy when of a diitcrent tint from the rell, are vifible througli the fub- Itance of tlie cryftal ; a phenomenon produced by a fuper- pofition of cryilalline matter on the cryllal already formed. 21. Acute flximbotd of ^o" ^A^ , and 1 29° 6'. — This occurs both fimple and combined with other modifications, fuchas Nos. I, 2, 3, 4, II, 17, and 46, in the Hartz, in Cumber- land, and more frequently in Derbylhire. It is often feen to accompany (lalaftitical varieties of calcareous Ipar. 22. Very acute rhjmbohi of T^-j' 3 i', and 142 29' — This is the chaux carb. ?7i:xtc of Hauy (pi. 23. lig. 6.) It is, like the preceding, not unfreqnently met with, particularly as accompanying ilaladtitical lime-ftone ; it occurs as often in a complete (late as combined with the planes of other m.o- difications, amonsc which are Nos. '3>4. and 46. They are principally found in Derbylhire. Tlie variety which is combined wdth the planes of No 4, has been de- fcribed by Haiiy under the name of utilmixte (Ann. du Iiluf. vol. i.) ; and that with the planes of No 1 1, and re- mains of the primitive planes, is called by the fame cryftal- lo'j-rapher chaux carb. tri-rhomhai(!a:e (Min. pi. 25. fig. 17.); that with additional tr.ices of the planes of No. 7, is his chaux carb. quadrl-rhomboidale (Ann. du Muf. vol. i.). When the planes of this variety, and thofe of Nos. 11 and 3, are united at the extremities of the prifmatic modification No. 2, it is Haiiy's chaux carb. ar.ntilaire (ibid.) 23. Extremely acute rhomboid of 14' 6', and l6j'' 54' This is the mod acute of all the rhomboids that belong to calca- reous fpar. It is feldom feen in its complete Itate, both on account of its minutenefs and its extreme fragility ; M. de Bournon has, however, obferved it feveral times on the groups of calcareous fpar from the Hartz, which are confider- ed as filiform and indeterminable. The combination of the planes of this with thofe of No. 4, is named ciiaux carb. ddatee by Haiiy (pi. 24. fig. 31.}, which occurs alfo as made ; that with traces of the planes of Nos. 3 and 17 is the fame cryilaliographer's chaux carb. hyperaxide (pi. 25. fig. ;o.) ; and that with Nos. 4 and 7, his chaux carb. rr/ro- ^rade (pi. 26. fig. 36.) It occurs alfo with the planes of feveral other modifications. This rhomboid might eafily be miltaken for that of No. 13, v/hicii is, however, the refult of quite a different decrement of the cryilalline laminx, aud con- fequently has a different cleavage. III. Pyramidal Modif.calions. The feveral pyramidal dodecahedrons belonging to this di- vifion, are here diilinguifned from each other by the mealure of the fohd angle of their lummit, taken on two oppofite edges of the pyr.nnid. A. Pyramidal obtufe dodecahedrons — The modifications of this fub-divifion of pyramidal dodecahedrons are, upon the whole, very rare, and almoft pccuhar to England, where they occur in Derbylhire, Cumberland, and Durham. When the planes of feveral of thofe modifications are combined in the fame cryftal, theur narrownefs, together with the very obtufe 3 angles they form with one another, fometimcs produces curvi- linear planes, efpecially when they are, at the fame time, com- bined with the planes of feveral of tlie rhomboidal modifications. The following ten modifications, with the exception of Nos. 27 and 30, have not been noticed before. 24 Obtufe pyramidal dodecahedron of i'^^' 28'. — This modi- fication (as well as thofe that follow), is the reiult of a retro- gradation of the cryftalline laminx, along, and parallel with, the edges of the pyramids of the primitive rhomboid, replacing each of thefe edges by a double plane or bevelment. Three of the edges in each pyramid of this modification muft, there- fore, be exaftly in the fame direftion with thofe of the primi- tive rhomboid. It has not been obferved either in its pallage from the primitive rhomboid, or as complete dodecahedron, but only in combination with very fhort planes of the prifm No. 2 (from Cumberland) ; with thofe of Nos. 2, 4, and 36, in a pyramidal cryftal from Derbylhire ; and with thofe of Nos. 2 and 3 j, from the fame county. 23' . Obtufe pyramidal dodecahedron &/' i 26 ^ 5 1 '. — This modi- fication, if it exiiled in a complete Hate, woidd exhibit py- ramids with planes forming ifolceles triangles, and conle- quently with all the angles of the common bafeon the fame level. M. de Bournon has but twice obferved this modifica- tion ; and in both cafes combined with the planes of leveral othei' modifications, among which thofe of the prilm No. 2 are the moft apparent. From Derbyfliire. 26. Obtufe pyramidal dodecahedron of 124' 36'. — This is of much more frequent occurrence th;m the preceding, from which it differs eflentially, in having fcalene triangles. The complete dodecahedron comes from Derbylhire ; a combina- tion of its planes with thofe of No. 2 from Cumberland. In Derbyfliire it is alfo found combined with the planes of feveral other modifications, of which thofe of Nos. 2 and 36 are the moft chaiaiSeriftic. 27. Obtufe pyramidal dodecahedron of 121° 26'. — Theplanes that terminate Haiiy's chaux cavh . Joti/lraffive ipl. 26.fig.37.) belong to this modification. They are alio feen in his chaux carh. furcompofee (pi. 28. fig. 50.), in w'hich five mo- difications are combined. Cryltals with planes of this dode- cahedron are common in Derbylhire and Cumberland, where it occurs combined with the planes of feveral other mod;fi« cations. The complete dodecahedron is Icarce. 28. Obtufe pyramidal dodecahedron of 118" 26'. — Has not yet been found in a complete llate. The fimpleft combina- tion is that with the very Ihort planes of the prifmatic modi- , fication No. 2. But it generally occurs together with the planes of feveral other modifications, fuch as with Nos. 4, 7, II, 27, 28, and 36, and in lome of thefe alio, with re- mains of the planes of the primitive rhomboid. Found prin- cipally in Derbylhire and Cumberland. 2 9. Cltufe pyramidal dodecahedron of 11 J 25 '. — Differs but little from the preceding. It has not been found in a complete ftate, nor are its planes often ftcn combined with thole of other modifications j among thofe figured by M. de Bournon are Nos. 2, 15, 17, and 36. The cryftals which exhibit its planes are moftly from Derbylhire. 30. Oblufe pyramidal dodecahedron of T 1 ^ 17'. — Its planes- are reprefenled in Hauy's chaux carb. diijainte (pi. 26, fig, 38.), in which it is combined' with thofe of Nos. 2 and 36. In the fame author's chaux carb. bint^enaire (Ann. du Muf. vol. i. ) it is feen without the planes of tlie prifmatic modif. No. 2, but with thofe of No. 36 ; and his chaux carb. additive (ibid.) is the bifonaire, augmented by the planes of No. 4. Thefe cryftals are faid to come from Derbylhire. M. de Bour'ion has not iiimfelf ftcn cryftals with planes of this modification, 51. Cltife L I M E. 31. Obtuft ptramlJiil dodecahihoii of 100' 24'.— The •planes produced by ihc retrogradAtiou of the cryftalliiie lainiiire replace the edges of the primitive rhomboid, but iiiftead of being parallel to them, as in the precedinj; modili- CHtions, they become narrower towards the fummit ot the rhomboid. The two pyramids of this dodecahedron arc, like thofe of No. 25, compofcd of ifofcelcs triangles, whence the angles of their hnfe mull be upon a level. It has not yet been obferved in. it- complete (late; but in a variety compoled of its planes and thofe of Nos. 35 ?,nd 2, M. de Bournon has feen it terminate the cry Hal in a very regular manner. It has alfo been obfervyd in a cryftal in which the planes of No. 2, and in another in which llioi'e of No. 36. arc predomi- nant. 'J^ic cry llals exhibiting the planes of this modification are rare, and have been found only in Dcrbyfliire and Cum- berland. 32. Obtufc pyramidal dodecahedron of lOl" 6'. — This has not been feen complete, but in combination with the phinej of feveral other moditicalions producing very complica'cd f the planes of this modilication, and thofe of Nos. 2 and 4, forming altogether a cryftal of 24 trape- zoidal planes, not unlike thole of the leucite, except that in the former the planes are of three different dimtnfions. This modification is alfo of;cn feen in combination with the planes of No. 1 1 ; the variety in whi.li thefe latter have much increafed in fize at the expence of the former, is Haiiy's chaux carb. blnoleriiaire (pi. 2 ;. fig 25.) ; the fame cryftal is alfo obfervt-d as made. A fimilar variety, but which contains alfo narrow planes of Nos. 4 and 17, is the chiuix carb. doublaute of the fame cryftallographer, (pi. 27. The pyramidal variety of this modification with p'anes of Nos 17 and 11, is Haiiy's chaux carb. progrejft-ve (pi. 27. fig. 41.) ; and a fimilar one, but with the pbnes of 1 No. 2 inilead of II, is the fame auiiior's chaux carb. emoujfee (pi. 26. fig. 40.) ; the latter occurs alfo as made. Many more combinations of the planes of this modification, with thofe of others, are defcribed and figured by count Bournon ; among others a cryftal, compofeo of feven modi- fications, contains, in all, fixty planes, and another, com- pofed of eleven modifications, exhibits no lefs than 96 planets. The fame author has ilhiftrated this modification by 129 fignres. 37. yseute pyramidal dodecahedron of 40' 14'. — Though the dodcCdliedron of this modification is confidcrably more acute than that of the preceding modification ; yet it ap- pears to have hitherto been confounded with it. It has been found in combination with the planes of the primitive rhomboid, and thofe of Nos. 36, 2, and 11, and alfo ia its complete ilate. The cryftals exhibiting this modification are pretty large. They have been found only in the Dauphiiie Alps of Loifan, and in Derbyfhire. 38. P yrnimdal dodecahedron of ^f' 5'. — This might eafily {je miftaken for the dodecahedron of t lie preceding modifica- tion. It has not yet been obferved in its complete ftatc, but in LIME. in combination with tTie planes of Hos. 2, 5, ly, 17, 23, and wil'i remains of thj planes of tlie primitive rhomboid. Ha^ been found in Hungary, and other places ; but does not appear to occur in Enirland. 39. PyramlLd doJ.'cah^dron of icp 58'. — The complete do- decihedron occurs in Germany ; nearly complete, with planes of Ml. t7 at the points of the pyramids, it is Haiiy's chaux 42', and three under one of 112^44'. The complete do. decahedron of thss modilicaticn is fcarce, but occurs in Der- by(hire. In combination willi the planes of other modifica- tions, particularly with Nos. 2 and 14; 2, 14, and 47; 2, 4, and 50, it is found in Derbyfliire and Cumberhmd ; and com- bined \yith planes of feveral other rr:odii;cations, count B jurnon has fecn it among the cryHals of calcareous fpar c^rh. fixilttodkhnih (p!..2J. fig. 22); with the fummit that accompany the filver ores of Potofi; one of thefe cr'\-f. interceoted by N" 3, and with trapezoidal planes of No. 2, tals, the refult of eight moditications, has 66 planes it cOTlH'.utes the fame crylhiiograplier's ciiaux carb. oc!ode- Haiiy's i haux carb. num!:riqui{\. des Min.

Alfo the variety defcribed by Hsiiy under the name oi qu'tntiforme, (Ann. da Muf. vol. ii.) has fmall planes of this :?9;h modification, which has hitherto been found principally in Ger.nany. 40. Acute pyran'id^.l dodecahedron of 26^ 34'. — This dode- cahedron is not unfrequently feen i;i its complete ftate, but 06.) ap- proaches very near this modiiicalion in the meafurement of its angles. 4j. Acute pyramidal dulecahedron of ^6' Jo'.— Mio-ht eafily be miftaken for the dodecahedron. No. 36, in which, however,, the cleavage takes place on the more obtufe edges. The do- decahedron in its complete ftate ha.": been found in Derbviliire, wliere this modification occurs in combination with the planes of feveral others; the mo!f complic:ited among them is a cryftal, produced by ten modifications, five of which belong its points, on account of their great fragility, are generally to rhomboids and four to dodecahedrons, which, together broken. It occurs in Germany, from wiiich country, and with the planes of the prifra No. 2, form a cryllal of 84 from Derbyfhire and Cumberland, are alfj procured groups plane?, of crvltals, including the plaaes of this modification, in com- bination with others, fuch as Nos. i, 2, 3, 17, 19, 21, 22, 59, and 50. 41. Acute pyramidal dodecahedron of 1 3 53'- — This is the lail, and at the fame time the moit acute, of the feries of pyramidal dodecahedrons produced by a decrement along the edges of the bafe of the primitive rhomboid, and confe- 46. Acute pyramidal dodecahedron of 40 2^'. — Refembles the dodecahedron, No 45, with regard tothe inclination of its planes to each other ; but it is much more acute.- On the otiier hand it approaches near the dodecahedron, No. j6, in the meafurement of the folid angle of its fum- mit ; but in thi« the inclination of the planes is different,., not to mention the difference in the cleavagfe. This dode- {j'lently with cleavage at the fummit on the more obtufe cahedron in its compL te ftate is very fcarce, it has, however edges of the pyramid. This dodecahedron occurs complete, been found in Derby fti.ire and Cumberland ; the combinations of its planes with thofe of other modifications, fuch as Nos. I, 2, 3, 4, 6, 17, id, and thofe of the primitive rhomboid, are more frequently met with in thofe oarts of England. 47. Acute pyramtiLd dodecahedron of 45" 2'.— This appears- to be peculiar to the fame places, in which the cryftals wi'th the planes of the preceding modification are found. The complete dodecahedron is feldom feen. It is moft frequently found in combination with theprifm No. 2: the ano-Ics of three alternate edges being very obtufe, its pyittmid appears al- moR trian^'ular. Thefe cryllals are in general very tranf- parent and beautiful. 48. Acute py. amdal dodecahedron of 44" la'. — This is but little more acute than the dodecahedron of the preceding modification ; but the planes of the latter meet each other, three under an angle of 163' 50', and three under one of 84^ ; while in this 48th modification the fame planes meet three under 150° 8', and three under 97' 12'. The dode- cahedron in its complete ftate has not yet been found. Its- planes occur in cryftals from Cumberland and Derbylhire, in combination with thofe of Nos. 2, 14, ^2, 36, and 4J. 48*. Acute pyram-dal dodecahedron of ifV 3.1'. — The planes, of this modification are thofe marlted x in the figures of Haiiy's chaux carb. paradoxal (pi. 27. fig. 42.)^ delojiquf (ib. fig. 46.), -a-cA contplexe (ib. fig. 43.) 49. Acute pyramidal dodecahedron of ^g 9'. — The dodecahe- dron of this modification in its compiote ftate is from Hun- gary. Combined with the planes of (everal other modifica- tions, it occurs principally in Derbyfnire; one of the cryl- 44. AcuJe dodecahedral pyramid of 61'^ 4"]'. — Thmigh the tals from thence, figured by count Bournon, is compofed of olid angle of the fummit of this dodecahedron differs but 90 planes, being the refult of nine modifications. hut, on account of its great fragility, is generally feen in a broken ftate ; fometimes two oppofite planes of the pyramid, having increafed is fize, fo that they meet no longer in a point, give rife to cuneiform pyramids. Nor is it uncom- mon to fee four oppofite planes in the fame cafe. Such cryftals bear great refemb'aace to certain varieties of arra- gonite, from which they are, however, eafily diftinguifhed by their much greater fragility, and by their lamellar ftruclure. It has been obferved with veftiges of the primi- tive planes, and in combination with thofe of feveral other modi'u-ations : in one cryftal there are no lefs than 60 planes, being the refult of feven different modifications. The cryftals exhibiting planes of this modification are moftly found in Cumberland, Derbyftiire, and on the Hartz. 42. Acute pyramidal dodecahedron of 6-^^ ^y'. — With this bf^gins the feries of thofe dodecahedrons which are the refult of a decrement of the lamiris at the acute angles, on the bafe of the primitive rhomboid. Hence the cleavage takes place at the fummit on the lefs obtufe edges. Is found in its complete ftate, and combine.! v/ith the planes of Nos. 36, and 36 and 2, in Derbyihire ; but belongs to the more fcarce raodilications of calcareous fpar. 43. Acute dodecakedral pyramid of 63' 36^ — This has been found in a complete ftate in Derbyfhire, where, as well as in Cumberlaiid, it occurs alfo combined with the planes of feveral other modifications, forming, in fome inftances, very complicated cryftals, fuch as that of fig. 476 in the work before us, the 102 planes of which are the refult of eleven modifications. little from that of the preceding modification, yet there is a great difference in the inclination of their planes ; in the pre- ceding dodecahedron thefe meet each other under three angles of I j8' 22', and three others of 96^ 40', while in this 44th moiificatioa they meet three of them under an aiigis of 140'' 90 planes, being ' JO. A.itte pyramidal dodecahedron of 2^" 25'. — To this pro- bably belong the pyramidal planes of Haiiy's chaux carb, acutangle. This modification has hitherto been principally found on the Hartz, it occurs however alfo, combined witiu- the planes of feveral others, in Derbyfhire apd otter parts L I M E. rf England'; the crylb's that exhibit its planes frequently accompany ftalaclitical carbonate of lime. 'Die complete dodecahedron has not yet been found. 5 1 . Acute pyramidnl iloJnahcJron of 14° 30'. — The planes of the very acute pyramids of tliis modification are of rare occurrence ; and in its complete ibue the dodecahedron has not been feen at all. The cryilals from Dcrbylhire, en which its planes have been obferved, are the refults, fome of fix, others of leven and eleven, different modifications. 53. Acute pyramidal iloJucahcdron of 18° 26 . — Though this and the two following dodecaliedrons are, like ihofe of the preceding modifications, the reiult of an intermediate decre- ment of the cryftalline lamince on the acute angles of the planes at the bafc of the primitive rliomboid, yet they differ from the latter in the cleavage, which takes place on their more obtufe edges. This dodecahedron has not yet been found in its complete ftate ; in combination with the planes of feveral other'modifications, of which thofe of No. 36 are the molt confiderable, it is found in Derbyfhire 5 5 . Acute pyramidal dodccahcdnn of 16 $^ '. — M. de Bour- nonhas obferved the planes of this modilication only in two cryllals from Saxony, where they fometinics accompany red filver ore. This is undoubtedly the fcarcefl; of all mo- difications of calcareous fpar, and one of the few that are not found in England. 54. Acute pyramidal dodecahedron of 14° 4'. — This is the moll acute of all dodecahedrons hitherto obfervedincalcareous fpar. It differs but little in this refpeft from that of No. 5 1 ; but independently of the confiderable diffe.-cnce in the re- fpeftive inclination of their planes to each other, the cleavage of the former is on the lefs obtufe edges, while that of this modification takes place on the moll 'obtufe edges. M. de Bournon has obferved the planes of this modification in two varieties only ; the one is the dodecahedron in its complete Hate ; the other exhibits its planes combined with thofe of 'Ho. 13, which latter happens to be the moll acute of all rhomboids hitherto obferved of this fubllancc. Both varieties were found in Weftmoreland. 5 J. Acute pyramidal dodecahedron o/"34^i2'. — This dode- cahedron,like thofe of Nos. 25 and3 1, iscompofedof ifofcelcs triangles. Count Bournon has obferved this rare modifica- tion in a few cryllals from Derbyfhire, in combination with the planes of the primitive rhomboid, and thofe cf Nos. 2 and 4. IV. Dodecahedral prifmatic Alodiftcation. c6. Dodecahedral prifm formed at the folid angles of the lafe. (not before defcribed) Its planes arc produced by a retro- gradation of the cryilalline laminse on the folid angles, fo a.s 10 replace each of them by two planes which meet under an ann^leof 142 1' ■ Its planes are found combined with thofe of the hexahedral prifm No. 2, which give the cryftal the form of a prifm of 18 fides; in other cryllals which, be- fidesthejufl mentioned planes, cchnprife alfo thofe of No. i, the prifm is compofed of 24 fides. It has been likewife found in combination with the planes of fix different modifi- cations, four of which belong to dodecahedrons, one to the prifm of No. 2, and one to No. 56, producing in all 66 planes. Another variety has been obferved by count Bournon, which, in addition to the planes of the lall-men- tioned variety, contains alfo thofe of the prifm No. I, and is confequently compofed of 72 planes. This modification, wl ich has been found in Cumberland, is rare, but it is not improbable that its planes may be thofe of feveral of the curvilinear x-arieties already mentioned, but which cannot be determined by the goniometer. Tiie cryftals of calc*reous fpar are varioufly aggregated, and often fo deeply imbedded, that their fummits only are vifible. They occur of all degrees of magnitude, from mi- nute to 14 inches in length ; their furfacc is generally fmooth, fometimes flreaked or drufed. Externally from fiiining and fplendent, to dull, fometimes pearly ; internal luihe from fplendent and fpccularly fplendent, to fhining ai/d gliilening ; it is nioilly a vitreous lullic, the intenfity of which is gene- rally in proportion with the tranfparency of the cryftal. Fracture foliated, rarely curved foliated ; fragments rhomboidal. The maffive is generally found in large-grained diftinft concretions, but alfo fometimes in lellaceous, wedgt- fhaped, and diverging, more or lefs flreaked prifmatic ctiu- cretions. Tranfparency both of mafTue and cryftallizej calcareous fpar is various ; the former is however generally only tranflu- cent, while the cryflals are mollly femi-tianfparent and tranfpareiit ; and thefe poffefs the double refratlion in a high degree. It is femi-hard, between gypfum and fluor fpar, or, (ai count Bournon charadlerifes its hardnefs,) jull Icratched by common brafs. It is brittle, eafily frangible. Specific gravity 27.17 as a mean. Bourn. Some varieties, efpecially that of brownilh-yellow colour, and part of thofe found in the fhell marble of Derbyfliire, are pholphorefcent when laid on a hot coal. The fame qua- lity has been obferved, by Schumacher, in varieties from Nor- way. Its chemical charaflers agree with thofe of the preceding fub-fpecies. The purell Iceland fpar is compofed of Lime 55,0 55.5 Carbonic acid 34.0 44. Water ii.o o.i 100 Bcrgm. 100 ~ f Phillips Phil. 1 Mag. xiv. This fub-fpecies is found in motl parts of the world ; but mod abundantly it occurs in England (where almoll all modifications have been found), in Saxony and France. Certain cryflal-forms appear to be peculiar to certain coim- tries or localities ; but this requires farther obfervations. With regard to the Iceland fpar it ihould be remarked, that this very pure mafTive variety of calcareous fpar, is far from being peculiar to that ifland ; at Pergine, in Italy, as we are told by Buch, the fame occurs in mica flate, as nialTes fufTiciently large to be cleft into rhomboids of upwards of two feet in length. Calcareous tpar is, almofl without exception, the pro- duftioii of particular repofitorics ; it is never feen to form independent beds or flrata. It occurs vcnigenons in the rocks of almofl all formations ; in the oldell ; in Switzerland and the Pyrenees, it is accompanied with feldfpar, rock- cryftal, &c. Alfo frequently in various metalliferous veins in gneifs, mica Dale, clay flate, fienite, porphyry, more feldom in granite, frequently in granwacke, and with ores of cobalt and copocr, in the older fietz lime-flone. The newer fle'z lime-iione is fometimes travcrled by veins entirely compofed of calcareous fpar. The minerals ufually accompanying calcareous fpar are granular and comoaft lime-llone, brown fpar, quart/., feld- fpar, barytes, fluor fpar, clay fiate, chlorite, iron and cop- per pyrites, fpathofe iron, brown iron-flone, galena, blende, grey copper ore, malachite, &c. 3 .

Satin fpar. Its LIME. Its colours are white, greyiffi, rcddiffi and yellowidi- ^■hite. It occurs madivc. Internally it is between gliAening and fhining, with a pearly or fatiny luftre. Crols-fraclure compaft fplintcry ; longitudinal fraclure ftraight or waved, fibrous; the fibres (wliicli may be con- fidered as indeterminable cryftals) are cither llrongly ad- hering to each other, and parallel, or partly detached, and tapering ; they have alfo been feen reticularly aggregated. Fragments in moll varieties fplintery, alfo flattened fibrous ; flrongly traiiflucent. Hardnefs rather lefs than that of cal- careous fpar, which it refembles in the remainder of its cha- racters. Its conllituent parts were found by Mr. Pepys to be Carbonic acid 47-6 Lime 50.1 Water and lofs 100. o Phil. Mag. xij. It is a produdl of veins. The fmell variety of fibrous llme-ft one is that of Cumber- laud, to which the name of fatin fpar is peculiarly appli- different ftates, according to the particular circuniftances under which it exilLs. When newly made, from its great power ot deftroying the texture of bodios, it is termed cauftic or quick lime. It is alio fometimes called flicll-lime or rticUs. In this (late, when ufcd as manure, it operates with the greatell violence, dif- flpating and robbing the foils, to winch it is applied, of their inoiflnre and other fluid mat'tr : but after being ex- pofed to the atmofphere for fome time, from its property of quicl'ly abforbing moilUue and carbonic acid from it, it be- comes mild or effete, and is termed carbonat of lime. When applied to land in this Hate, it ads with much more mildi.el's, orily promoting the refoliition of the matters in which it comes in contadt, by forwarding the natural procefs of putrefai'tion. It has alfo lefs tendency to produce a mortary hardnefs in the poorer forts of clayey foils. But befides thefe dilTerence£, there are others arillng from tlie fubllances which are combined with the calcareous matters employed, as liar, been lately (liewn by the ingenious ex- periments of Mr. Tennant, itatcd in the fecond part of tlie Philofophical Tranfaftions for the year 1799. Having been informed that two kinds of lime were uled in agricul- ture, which differed greatly in their effeils,— one of which it was neceffary to ufe fparingly, and to fpread very evenly over the land, as it was faid that a large proportion of it diminidied the fertility of the foil, and tliat, wherever a heap of it had been lefc on one fpot, all vegetation was pre- vented for many years ; and that of this kmd of lime, 50 or 60 bufhels on an acre were as much as could be uftd with advantage ; wliile of the other fort of lime, a large quantity was never found to be injurious, and that the (pots which were entirely covered with it became remarkably fertile, in- ftead of being rendered barren : — having analyled thofe two kinds of lime, he found that the latter conlilted lolely of cal- careous earth ; but that the former contained two parts of magnelia, with three parts of calcareous earth. He after- wards proved, that though vegetable feeds would grow equally well in both thefe kinds of lime-llone, when (imply reduced to powder ; yet that, when they were calcined ((* as to become lime, and both of them flrewed about the tenth of an inch thick on garden mould, the niagnedan lime pre- vented nearly all the feeds which had been fowed from coming up, while no injury was occafioiied by the calcareous lime, when ufed under the fame circumdances. It may be noticed, that this valuable difcovery feems in fome meafure to explain the caufe of the variety of opinion that has been maintained refpedting the application of lime, which fome have fuppofed to be of little or no advantage, and even injurious to land ; which has been owing probably to their having employed the magiiedan lime, or ufed it in too large proportions. This philofophical inquirer firft found magnefian lime near the town of Doncader, and afterwards at York, at Matlock in Derbvfhire, at Breeden in Leicellerdiire, and at Work(op in Nottingliamfliire. He alfcrts, that the cathe- dral and walls of York are built with this magnefian lime- done ; and that at Matlock the magnefian and calcareous lime-dones are contiguous to each other, the rocks on the fide of the river Derwent, where the houfes are built, being magnefian, and on the other fide calcareous. He found alfo, that in this fituation the magnefian lime-done was in- cumbent on the calcareous : for, in defcending into a cavern formed in that rock, he found a feparate vein of calcareous lime-Hone, which was fuU of fliells, but contained no mag.- nclia : LIME. nefia : awi concludes, tliat, in general, the magnefian lime- ftone may be eafilv diflinguilhed from the calcareous, by its folutio^ in acids beitii; much flower, and that it contains generally very few (hell? ; but that thcfe, when prefent, are impregnated with magnelia. In the Philofophy of Agriculture it is remarked alfo, that all lime-ftone may be divided into three kinds : firft, the rocks which remain, where they were formed from (lieUs beneath the ocean, except that they were afterwards ele- vated by fub-marine fires ; fecondly, into alluvial lime-ftone, as thofe which have been diftblved in water, and fimply pre- cipitated, as the beds of chalk, which contain only the molt infoluble remains of fea animals, as the teeth of Iharks ; and, thirdly, thofe which, after having been diffblved and pre- cipitated, have been long agitated beneath the fea, till the particle? have been rolled fo againft each other, as to acquire a (rlobular form, which is faid to refemble the roe or fpawn of fiih, and which contain very few fhells, or none, as the Ketton ftone, and that which he ha? feen on Lincoln heath, extending almoft from Sleuford to Lincoln. Now, fays he, as the falts of the fea confift of only two kinds ; common fait, or muriat of foda, and vitriolated magnefia, commonly called Epfom fait, %vhich, in the fea-waters furrounding this idand, are found at a medium to exill in the proportion of one-thirtieth part of common fait and one-eightieth part of vitriolated magnefia, compared to the quantity of water ; and, fecondly, as thefe falts are believed by many philo- fophers to have been formed by vegetable and animal mat- ters, which principally grew upon the furtace of the dry land, after it was raifed out of the primeval ocean ; and that, in confcquence, the faltnefs of the fea was pofterior to the formation of the primeval rocks of lime-ftone ; we may underftand why thofe lime-ftone ftrata, which have not been diflolved or v.-aftied in fea-water fince the fea be- came fait, are not mixed with magnefia. The chalk, he fuppofes, muft hai-e been dinblvcd and precipitated from water, as it exacllv refembles the internal part of fome cal- careous ftalaftites which he has in his pofTefiion ; yet there is no appearance *,of its component particles having been rubbed together into fmall globules, and may not, there- fore, have been removed from the fituation where it was produced, except by its, elevation above the furface of the ocean. But that alluvial lime-ftone, which confitts of fmall globules adhering together, called Ketton lime-ftone, and of which there appears to be a bed lo miles broad from Beckingham to Sleaford in Lincolnfhire, and 20 miles long fron Sleaford to Lincoln, he fulpefts may probably confill of magnefian lime-ftone ; which is alfo faid in that country to do no fervice to vegetation : tor this alluvial lime-ftone, by having evidently been rolled together beneath the fea, by v/hich the fmall cryftallized parts of it have had their angles nibbed off, is moft likely to have thus been mixed with the magnefia of the lea-water, which, as has been obferved, is laid to contain one-eightieth part of its weight of vitriolated magnefia. It is further remarked, that at the lime-works at Ticknal, rear Derby, there appears a ftratum of alluvial lime-ftone, like K.e;ton lime-ftone, which they do not burn for fale, over the bed of the calcareous lime-ftone, which they get from beneath the former, and calcine for fale. It is pro- bable, he thinks, tkat the fuperior bed may contain mag- nefia, which has rendered it not fo ufeful in agriculture. It is ftlU more probable that alluvial Iime-ftone has acquired its mixture of magnefia from the fea-water ; as magnefia, in its uncalcined ftate, will precipitate lime from water, as ob- served by Dr. Alilon, who thence propofes to render water pure and potable, wliich has been long kept at fea free from putridity by having lime mixed with it, by precipitating" the lime by the addition of mild magnefia. The lime from Brcedon is magnefian, that from Ticknal (which is fold) is calcareous, he believes ; and fome farmers in the vicinity of Derby affert, that two loads of Breedon lime will go as far, that is, will apparently do as much fer- vice to their land, as three loads of Ticknal lime. Breedon lime, he is alfo informed, is preferred in architeiture, and is faid to go further in making mortar ; which, he fuppofes, means that it requires more fand to be mixed with it. In the Account of the Agriculture of the Midland Counties, lime made at Brcedon, near Derby, is faid to be deftruftive to vegetables, when ulcd in large quantities ; and in Not- tinghamftiire it is aflerted, that the iime from Critch, in Derbyfliire, is fo mild, that thiftles and grafs fpring up through the edges of large heaps of it, when laid in the fields. Dr. Fenwick of Newcaitle obfervcs, that the farmers in that country divide hme into hot and mild; whicii Mr. Tennant believes to mean magnefian and calcareous lime. By experiments which were made by Mr. Tennaitt, by fowing feeds of colevvort on various mixtures of calcined magnefia with foil, and of calcareous lime with foil, he found thirty or forty grains of lime did not retard the growth of feeds more than three or four of calcined mag- nefia : hence, what can we conclude, but that, as thev both injure vegetation in large quantities, they may both affill vegetation in fmall ones ? and that this is more probable, as the farmers believe that they find both of them ufeful, though in different quantities ; and as the magnefia would form Epfom fait, if it met with vitriolic acid, which Dr. Home found, from his experiments, to be friendly to vege- tation, when ufed in very fmall quantities. More accurate obfervations and experiments are, however. Dr. Darwin thinks, wanting on this iubjeft. The moft certain way to know whether any fort of ftone be fit for making lime is to drop upon it a little aquafortis, fpirit of fea-falt, or oil of vitriol. All Hones on which the above, or any other ifrong acid, eflervefces or rifes in bub- bles, are calcareous Hones, or will burn to lime ; and the ilronger the effervefcence is, the titter they are for that pur- pofe. And as in the ufe of calcareous matter as a manure, much depends upon its being brought into a fine powdery ftate, it Ihould always, where fuel can be obtained at a moderate expence, be prepared by burning, as that is the eafieil and moft efficacious mode of reducing lime-ftone to powder that ever was invented, and therefore ought always to be adopted where neceffity does not prevent it. Reducing lime-ftone to powder by calcination is alfo, he remarks, attended with this farther advantage to the farmer, that it confiderably dimi- nifhes his expence of carriage. Pure lime-ftone lofes about two-thirds of its weight by being thoroughly burned ; fo that the man who is obliged to drive this manure from a great diftance, will find a very confiderable favingby driving it in the ftate of ihells ; but if it were reduced to a powder by mechanical 'rilure, he could not be benefited by this circum- ffance. Many perfons choofe to drive lime-ftone from a confiderable diftance and burn it at home ; but it is obvious they then fubjedl themfelves to a very heavy charge in car- riage, which would be avoided by an oppofite conduct. This, therefore, ought never to be praftilcd but where other cir- cumftances may counterbalance this unfavourable one. But as lime-ftone is often in iti native ftate mixed with fand in various proportions, and as fand lofes nothing of its weight by calcination, it muft happen that thofe kinds of lime-ftone which contain the largcft proportion of fand will lofe leaft ill calcination, and of courie alford the weighticll lime-fhells. Hence L 1 ME. Hence it is obvious, that thofe who are under tlie neceflity of driving lime from a great diftancc ouglit to be particularly careful to make choice of a kind of iime-ftonc as free from fand a^ polhble, and to drive it in the Hate of fliells, as they will thus obtain an equal quantity of manure at the leall expence of carriage that is polfihle ; and the lightell (hells enight, of ciurfe, to be always preferred. When lime is flaked, that which contains moft fand fall? mod quickly, and abforbs the fmallelt proportion of water. What is pure requires a very lart^e pro;x)rtion of water, and is much longer before it begins to fall. Hence it happens that thoi'e who drive fandy lime-(hells in open carriages, mull be very careful to guard againll rain, becaufe a heavy (hower would make the whole fall, and generate fuch a heat as to be in danger of fetting the carts on fire ; whereas pure lime-lhells are in no danger of being damaged by that circumftance. The writer has fecn a cart loaded with fuch fliells, which had been expofed to a continued fliower of rain, as violent as is ever known in this country, for more than three hours, and feemed hardly to be affecled by it in the fmallell degree. He ought, he fays, to obferve, however, that his experiments were con- fined to only one kind of pure lime, fo that it is not from hence demondrated that all kinds of pure lime will be pof- fefled of the fame qualities. Lime-fliells formed from the purefl lime-done require more than their own weiglit of water to flake them properly-, whereas, fome kinds of lime- ihells that contain much fand do not requite above one- fourth part of that quantity. He has found, by experi- ment, tliat pure lime-fliells cannot be flaked with lefs than about one-fourth more than their own wciglit of water. When^flaked in the ordinary way, the fame lime-fliells took more thau double their weight of water. Hence it is much worfe economy, in thofe who have pure lime-fliells, to flake and carry them home in the date of powdered lime, than it is in thofe who have only a fandy kind of lime-fliells to make ufe of. It is farther fuggeded that it is even, on fome occafions, more advlfable for thofe who have very fandy lime, to drive it in the date of powdered lime than m that of fliells ; for, as it is dangerous to give that kind of limc-ftone too much heat, led it fliould be vitrified, thofe who burn it can never be certain that the whole of the done wi 1 fall to powder when Viiater is, added, till they have actually tried it ; nor do they think it a great lofs if fome part of it fliould be imperfeAly burned, as it requires much lefs fuel on a future occafion than frefli hme-llone ; and therefore they much ra- ther choofe to err on this than on the oppofite extreme. But fliotfld any one attempt to drive this poor fort of hme in the date of ihells, he would be in danger of carrying home many dones that would never fall ; which would more than counterbalance the benefit he would derive from the want of the fmall quantity of water that is required to flake it. On tliefe accounts it is fuppofed it may be admitted as a general rule, that thofe who can ha^'L• accefs to lime-done which is free of fand, will fave a great deal in the carriage of it by driving it in the date of fliells ; and that, on the con- trary, it will be mod economical, in thofe who can only get lime of a very fandy quality, to drive it in the Hate of powdered hme. Hence it follows, that the praftice which jio\r prevails, of carrying fliell-lime by water frim one part ■of the country to another, is only an imaginary laving, ob- lained at a very high rifl<, to thofe who drive fliells ot a fandy quality ; but a real and unequivocal advantage ot very Jiigh importance to the community at large, if thefc fliel's are obtancd from a pure lime-done. Thefe obfervations relate only to the faving of carriage to the farmer ; which, however, is.an article of great importance toiiiai. But there are fome other particulars that may alfo equally afleft him in this way, and in the application of the lime to his ground. A vague opinion in general prevails in every part of the country, that one fort of lime may be more valuable than another ; but it does ijot appear that farmers have hitherto had any rule to dircft them in the choice of different forts of lime ; fome cdeeniing one fort drongcfl;, as they term it, and fome valuing another fort more highly, without being able to.:i/Ggn any fatisfaftory reafon for the preference they give in eitlier cafe. It is of importance that this matter Ihould be elucidated. Although it docs not always happen, yet, in many parts of the country, the real nature of lime is fo little underdood, that the weightied lime is preferred as a manure to lliat which is lighter ; be- caufe it is imagined the firll has more fubilance, and will therefore produce a more powerful efleifi upon ground than the tinelt and lighted lime. But tliere fceir.s to be no rea- fon to think there is any diderence in the fpecific gravity of difleient parcels ot pure calcareous matter when fully cal- cined ; therefore, if there is any difierence in the v\ eight of various forts of lime, it mud arile entirely from a variation in the quantity or gravity of fome extraneous matter tliat i> mixed with the lime ; and as land is alniod the only extraneous body that is ever found in lime-llone, and is always of much greater fpecific gravity than pure quick-llnie, it follows, that the weighty lime only owes its fuperior gravity to a larger proportion of fand that is mixed with it. But fand is of no value as a manure ; io that he who voluntarily purchafe* this kind of lime in preference to the other is guilty of a great degree ot folly ; which will be tlie greater if he has likewife to drive it from a confiderable dillance. However, thole tarmers who have accefs to only .one fort of lime-done, mud be contented with it, wliatever may be its quality. But.fucli as have an opportunity of choofing may be benefited by the oblervation, that pure lime-ftone, when fully calcined and flaked, is reduced to a fine white impalpable powder that feels loft between the fingers, without the Imalled tendency to grittinefs ; while fuch lime as contains land is never fo fine nor fo foff, but feels gritty when rubbed between the liugers. See Aiiderfon's Edays. JlSion, Qjmnti/y, and yfjip/icatloti of Lime. — The author of Modern Agriculture remarks, that there are few didrifts where lime is not either in general ufe, or partially intro- duced as a manure. With refpcdt to the ufe of hme, or the benefit derived from it as a mean of fertilizing the foil, fome are of op;,i:on that it promotes vegetation, by ilimu- lating, or forcing the foil^ with which it is incorporated to exert itfelf : others .niiagine it promotes vegetatiuu by en- riching the foil, and thereby adding to the quantity of vege- table food. Various other opinions, different from thefe, and in fome indaaces oppollte to each other, have been entertained refpeiiing the manner in which lime operates upon land ; but all tliat we yet know with certainty on the fnbiect, is collected fr-^m praflice and experience, whereby it is proved that lime lomebow or other operates fo as fre- quently to produce luxuriant crops on foils which, before the application of that manure, were comparatively of little value,; and farther, that on all foils which are treated pro- perly after being thoroughly limed, its beneficial elfecls are .diicernible by the mod curfory obftrver. Various other modes in .which this fubdance may be ul'eful as a manure, may be feen under the terms Cakareous Eautji, and Piios- rjioitu.i. The proportion or quantity of lime appUed to the acre feenis hitherto, the fame writer obferves, fixed .by no certain rule, either in. regard to the nature of the different foils, the modes L I M E. modes of cropping afterwards adopted, or the fuperior qua- lity' of one kind of lime-ftone beyond another. It has been remarked, that fome require that it fhould be applied in fuch fmall quantities as thirty or forty bufhels to the acre ; and aVer, that if more is ufed the ground will be abfolutely ruined ; while others maintain, that ten times that quantity may be applied with iafety. A great varia- tion m:\y no doubt be produced, in this fefpec^, by a dif- ference in the nature of the foil, in the ftate of culture it fpread. The field was paftured upon for feven or eight years after that, before it was converted into tillage ; ■and the heaps were by that time become fo fiat, and fo far funfc into the ground, that they could hardly be difcovered. Before it was p-'.oughed up, the whole of tiie field was limed, and this part of it equally fo with the rell ; i:or were the old heaps touched till the plough went tljrough them irr tilling the field, when the lime was there turned up, with only a very fmall mixture of foil. The conlequeiice was. is under at the time, in the quantity of calcareous matter that at every one of thefe heaps, a tuft of corn fprung up with which it may have been formerly impregnated ; and with fuch luxuriance as to be entirely rotted before harvtlt ; perhaps a variation may fometimes arife from other cir- and for many years afterwards, thefe tufts could be dillin- cumllances that have never yet been attended to. A differ- guiihed from the other part of the field at a very great dif- ence will likewife arife from the quality of the lime that is tance, like fo many buttons on a coat ; and perhaps continue applied, and from the manner in which it is employed, fome fo to this day. From thefe experiments, as well as other kinds of lime containing, perhaps, ten times more calcareous confiderations, there fecms to be reaion to conclude, that matter than others ; and a very great difference may pro-- on foils which do not naturally abound with chalk, or other ceed from the mode of applying the lime itfelf. For it is calcareous m.atter, there is lefs danger in giving too much common to hear thofe who have had little experience of lime than in applying too littk, except in ihofe cafes where lime as a manure, recommend very great caution, left too an over luxuriance is to be apprehended previoufly to fuch great a quantity be employed, for fear of burning the limings. foil, as they exprefs it.

The expence, in moft cafe?, prevents farmers not to be at all employed. This, like many other objections from employing this manure in greater quantities than thofe to ufeful pradices, takes its rile entirely from the avarice above-mentioned ; but accidental circumllances clearly {hew, and unfkilfulnefs of thofe who complain. It is chiefly heard that if it were apphed in much larger quantities, theeffeft of in thofe parts of the country where it is not common for would on'y be to promot-e the luxuriance of the crop in a farmer, after once liming a poor foil, to take filteen. or fix- a higher degree.

Yet, fo far are thofe foils from being rendered flerile by it, that it is doubtful if any art, without the aflilhmce of lime, or fome calcareous matter, could ever have biouglit thefe fields to their prelent degre..- of fertility.

And, if by this qucllion it be meant to afcertain the length of time that the effefts of lime will be perceptible in promoting the luxuriance of the crop after one manuring, it is no wonder that very different anfwers ihould be given, as the effefts mud vary with the quantity or quality of the lime employed, tlie nature of the crops that follow, and many other circumllanccs, which it would be impoffible to enumerate. But if it he viewed in another light ; if lime be fuppofod to alter the foil, fo as to ren ground, which has been once impregnated with calcareou* matter, acquires qualities from that moment which it did not poffets before, whicli it ever afrerwards retains, and never returns cxaclly to its former (late.

Hence more feniiblc degree, fo as to make it capable of pro- ducing crops that no art could otiiervvi'o have effected, and to admit of being improved by mod<.s of culture that would not otherwife have produced any fenlible benefit, the anfwer to the queftion would be more cafy, as in this light, it is pretty plain that its effects will be felt, pcrhap?, as long as the foil exills. It is believed farmers are lel- dom accuilomed to confider lime, or other ca'ca^eous ma- nures, in this point of view ; although, when i comes to be inquired into, it is not doubted but thi-- will lie found to be by far the moft valuable effeft of ilicfe meafures. A few fafts will bell illullAte the meaning In D-.rby(hire the farmers have found, that by fprt adinL' 1 me in confider- able quantities upon the furface of their hea'hy moo s, afier a few years the heath difappcars, and the whole furface becomes covered with a fine pde ot grafs, coiifiding cf white clover, and the o.her valuable forii of pallurc graffes. it happens, that in ploughing, if there chance to be any lumps of calcareous matter in a dry Hate upon the furface, they naturally tumble into the bottom of the open furrow ar foon as the earth is edged up upon the mould-board, fo as to fall into the lowed place tiiat has been made by the plough before the furrow-flice is fairly turned over. In conlequence of this circumdance, it muft often happen that, in the courfe of many repeated ploughings, more of the lime will be accumulated at the bottom of the foil than m any other part of it ; and as the plough fometimea goes a little deeper than ordinary, the lime that on thefe occalions chances to be depofited in the bottom of thefe furrowp, will be below the ordinary ilaple of the foil, it will be ufelefa for the purpofes of the farmer, it is commonly thought that the lime has funk through the foil by its own gravity, although it is cer- tain that hme is fpecifically lighter than any foil, and can only be accumulated at the bottom of the mould by the« This (liews that lime renders the fod unfriendly to the growth means above defcribed : others think that the lime is chemi of heath, and friendly to that of cluer.

In the work on the prefent date of hufbandry in Great chiefly abound. The foil in either of thefe cafes may become equally poor ; that is, may produce equally fcanty crops : but the means of recovering them will be fomewhat different. In the hit cafe, a fallow feldom fails to prove beneficial. In the fird, it is often of no eifeft, fometimes even hurtful. In the lad, a moderate dreffmg of dun^ produces a much more fenfible and lading effedt thjn in the other. In the lad the quality of ihe grafs, as well as its quantity, rather improves by age. In the firl't thefe ci'-cumdances are reverfed. Several Other obfervations might be made, tending to fiiew that Britain, it is fuggeded as probable, that the propriety or im- propriety of repeated hmings depend more on the nature of the foil, and the modes of management afterwards adopted, th:in on any other circumdance connected with it ; and that, as in iome didritis it is repeated two or three times in the courie of twenty years, while in others a repetition of liming, except ill mixture with other fubltances, is found injurious, it is impoflible to account for fuch variations in the practice or its effects on the foil, without obferving, m the fird place, that although there has been as yet no general rule edabhfticd, by LIME. by which a farmer can dcterTitne what quantity ef lime is bed fuited to a particular foil, yet in praftice, a greater quantity is hid on ftrong, denfc, itubborn foils, than on thofe of a more friable nature. In the fecond place, that the diverfity of meafures by which lime is fold at the different kilns, is often fo great, as to leave it doubtful whether a farmer in one part of the ifland, who applies three chaldrons to the acre, does not ufe lefs than he who, in another dillrift, applies two. And in the third place, that the quality of linie-fhells is fo extremely different, that in forne cafes the farmer who lays five chaldrons on the acre, does not apply a greater quantity of effective manure than another who limes an acre with three only. And from various circumllances which have been already noticed, in fpeaking of calcareous earth, as well as from the great and general advantage of this fub- ftance on all foils and fituations, except fuch asareprevioudy replete with calcareous matter, or too moid, the writer of the " Philofophy of Agriculture" conceives, that its effedls can only be underftood from the idea of its aftually fupply- ing the nutrition of vegetables. This is ftill farther con- firmed, by its contributing fo much to the amelioration of the crops, as well as to their increafe in quantity, as noticed by millers and bakers. If it be applied in a large quantity, it likewife kills animals in the foils, and alfo fmall vegetables, and from the dellroyed and decayed animals and vegetables, the foil is rendered more fertile, by being impregnated with mucilage. The fuperabundant lime is ufeful as it becomes mild calcareous earth, by attracting carbonic acid from the atmofphere, and afterwards gradually affording it to plants. By the fermentation it brings on, and the finenefs of its par- ticles, the texture of the earth is opened and divided. It is evident that light fandy lands, containing only a fmall portion of vegetable matter, (hould not be overdone with lime, unlefs we can affift them liberally with animal manures. Its great excellence on a fandy foil is its mechanically binding the loofe particles, and preventing the different parts of the manure from efcaping out of the reach of the crop. On clay, by means of the gentle fermentation which lime pro- duces, the ftubborn foil is opened ; the manure readily comes into contact with every part of it, and the fibres of the plants have full liberty to fpread. It is often faid that lime anfwers better upon fand than clay ; but let the farmer treble the quan- tity, and he will be convinced that lime is better for clay than fand. Clay well limed becomes a marie, falling in water, and fermenting with acids ; the air, rain, and dews are freely ad- mitted, and the foil retains the nourifhment of each. In con- fequence of a fermentation raifed in the foil, the fixed air is fet at liberty, which in a wonderful manner promotes vege- tation. It is the nature of Kme, in its aftive ftate, to dif- folve vegetable bodies. Uporr this principle v/e may account for the wonderful effefts it produces in the improvement of black moor-land, which confifts of diffolved and half dif- folved vegetable fubllances. And it may be obferved in ge- neral, that the greateft quantity fhould be ufed upon the deeped and richeil foils, and the leail upon thofe that are thin and light. On drong clays and deep loams there is a fubdantial body forit to operEte upon ; confequently, a con- fiderable quantity will be required to pervade and give due aftivity to the whole ; but as the foil is lighter, the quantity mud be lefs, and the after-management in regard to crops extremely cautious. In liming a fingle field, an attention to the quantity will often be found neceffary : the foil of the higher parts being for the mod part light and free, and that of the lower more deep and compaft, v.here the ground is unequal. On fome foils, particularly where the bottom is chalk, lime-done, or marie, lime will be pernicious, efpecially if the foil be thin. Whatever be the method in which lime produces its bene- ficial effefts upon land, it fhould always be reduced into ae fine a powder ai poffible, and fpread out with the ^/reateft equality upon the foil, as by thefe means it will be more equally blended with it, and be more extenfively ufeful in promoting the growth of crops, Confidering lime as a fubdance operating upon the living fubdances in the foil, as weU as mechanically upon the foil itfelf, we perceive the neceflity of applying a fufficient quantity at once, in order to produce thefe effects: for, if the quantity employed be fmall, and the foil deep, its effcfts will be fcarcely perceived. Many farmers imagine that hme will not anfwer upon their lands, becaufe they have laid it on in Imall quantities, whereas in all probability they would have found a larger dofe highly beneficial. On clay, four or five hundred budiels are laid on for wheat, but it can fcarcely be expefted to anfwer theexpence. On mofs, bog, moor, &c. to be reclaimed from a ifate of nature, the more is hid on the better it is. The beneficial effe£t of Time on fandy land may be explained from its binding quality. But when fuch lands are fird broken up from their date of heath, the vege- table matter is afted upon and reduced to manure by the cor- rofive power of the lime. On fuch lands, the fird crop of rye has more than paid the expences. By attracting water, lime has a tendency to lay land dry. By infinuating itfelf between the particles of clay, it dedroys their adhefions, breaks the diffnefs of the foil, and gives readier accefs to the operation of manures, and to the extenfion of the growing roots of plants. By attiading carbonic acid, or fixed air and water, and by its corrofive properties, it dedroys the texture of bodies, and reduces vegetable matter to a date of manure. It unites drongly with oils, and renders thera mifcible with water. By being dedruftive to infefts and ver- min, it may alfo contribute to preferve the fpringing corn from their ravages. Dr. Anderfon, however, fuggeds, that, from writers on agriculture having long been in the cudom of dividing ma- nures into two claffes, viz. enriching manures, or thole that tended direftly to render the foil more prolific, however de- rile it may be, among the foremod of which was reckoned dung ; and exciting manures, or thofe that were fuppofed to have a tendency to render the foil more prolific, merely by adtiiig upon thofe enriching manures that had been for- merly in the foil, and giving them a new dimulus, fo as to enable them to operate anew upon that foil which they had formerly fertilized : in which clafs of dimulating manures lime was always allowed to hold the foremod rank ; it would follow, that lime could only be of ufe as a manure when ap- plied to rich foils ; and, when applied to poor foils, would produce hardly any, or even perhaps hurtful effedts. He acknowledges that he was fo far impofed upon by the beauty of this theory, as to be hurried along with the general cur- rent of mankind, in the firm periuafion of the truth of the obfervation, and for many years did not fufficicntly advert to thofe fads that were daily occurring to contradift it. He is now, however, firmly convinced, from repeated ob- fervations, that lime and other calcareous manures produce a much greater proportional improvement upon poor foils than on fuch as are richer ; and that lime alone, upon a poor foil, will, in many cafes, produce a much greater and more lalting degree of fertility than dung alone. In direft contradiction to the theory it is added, that he never yet met with a poor foil in its natural date, which was not benefited in a very great degree by calcareous matters, when adminidered in prooer quantities. But he has met v.-ith feveral rich foils that v^-ere fully impregnated with dung, and therefore exactly in that date in which the theory fuppofes that lime would H 2 produce LIME. ■produce the pfreatcft efFcA,— but upon wliiih lime, applied in anv quantities, produced not t1u> fniallfft fenfible effert. Tlic author of Pliytologia fiiggclls the idea of its fupplying aftual nutrition to vegetables, which fcoms probable, as it contributes fo much to the melioration of the crops, as well as to their increafe in quantity — wheat from land well limed being believed by farmers, millers, and bakers, to be, as they fuppofe, thinner (lra.

However, Mr. Dodgfon has had much fuccefs in burning lime by the ufe of peats ; as he ilates, in the Farmer's Ma- gazine, that he is " convinced, from experience, that lime- ftone can be burnt to better purpofe, and at lefs expence, with peat than with coal. When coal is ufed, the lime- Aones are apt, from exceflive heat, to run into a folid lump, which never happens with peat, as it keeps them in an open flate, and admits the air freely. The procefs of burning, alfo, goes on more flowly with coal. No lime can be drawn for t'AO or three days ; whereas, with peat, it may be drawn within twelve hours after tire is put to the kiln ; and in every fucceeding day nearly double the quantity of what could be produced by the ule of coal. The expence is compara- tively fmall. A mail and a boy will dig as many peats in one day as will burn 60 Carlifle bufhejs of lime, (the Car- lifle bulTiel is equal to three Winchefter ones,) and the ex- pence, including drying, will not exceed four, or, at mort, five Ihillings ; while the coal neceffary for burning the fame quantity of lime would have colt twelve fhilhngs at the pit. The wetnefs of feafons is no argument againft the ufe of peats, as they can be Hacked ne^r the kiln, when half dry, at any time of furomer^ the moifture will be exhaled from L I M them during winter, and they will be in a fit flate for burn- ing in the months of April or May. He lives in the north- eallern diltriifl of Cumberland, where the farmers, in general, burti their own lime ; a:.d though there is coal in ihe im- mediate neighbourhood, he gives a decided prefere. ce to peat, for the reafons above-mentioned." And it is well known, that this kind of fuel has been occafionally ufid in many parts of the kingdom for the fame purpcfe, from a very early period, without any complaint of the want of fuccefs. In the praftice here ftated, no particular form of kihi was found neceffary, nor any particular fort of management in the procefs of calcination ; the proportion of peat de- pending upon the nature of the Lme-ltone employed, and other circumftances. It has been confidered by Mr. Marihall, that " the manu- fadlure of lime is an art of which tl-.e manajrer of an eftate ought not to be ignorant." And he conceives, that "he ought to have, at lealt, a fufRti n' knov^l dge of its theory, to enable him, when occafion requl es, to fuptrintend or di- reft its prailice. For it feld >m anfwers, uniefs where ma- terials are plentiful and fuel cheap, for every tenant upon an eftate to manufacture his own lime. A full-fi/.ed kiln accu- mulates a (tronger heat, with a given proportion of fuel, than a fmali one of the fame for.-n," whicU is without doubt a great favifg. It is fuppofed, that " the chief or fole intention of burning lime- flone for manure, appears to be that of reducing it in the readiefl; and cheapeft manner to an impalpable powder. For experience fufficiently fliews, that quick lime is injurious, rather than beneficial, to vegetation ; and that burnt hme- fjone does not operate as a manure until it has regained the fixed air, of which the fire deprived it. If it could be reduced by mechanic powers to powder of equal finenefs, its eftefl, as manure, would doubtlefsly be the fame as that of dead hme (effete). It is in the perfeft folution which well-burnt lime-ftone has received, by the expulfion of its fixed air in the fire, fo as to have completely loofened its texture, and unbound its every atom, that we are to look for its prompt effect and the fhortnefs of its duration, comparatively with unburnt calcareoi-s fubftances. Hence the main point to be attended to is to expel the whole of the air. For, uniefs this be accomplifhed, the foluticn be- comes imperfeft ; the ftones, inftead of completely diffo'ving into impalpable atoms, break into granules, or flakes ; leav- ing, perhaps, a firm cere in the centre, to encumber, ra- ther than to fertilize, the foil" on whicli they are apphed. " There is, however, an oppofite extreme to be avoided, and with greater care. For an unburnt ftone may be returned to the kiln, but one which, by too intenfe a heat, is vitrified, or changed to a ftate of impure glafs, is not only rendered ufelefs, but has incurred an extraordinary wafte cf fucL Conlequently, ftones that are prone to vitrification ought to be broken down into fmall pieces ; otherwife, the fire is required to be fo intenfe, that the furface becomes vitrified, before the air from the centre can be expelled." And " another fuggeftion, refpefting the proper iize of the ftones to be burnt, may have its ufe. Where fuel is weak, or dear, the materials require to be broken into fmaller fragments, than where aftrong fire can be kept up at a fmail expence ; while, under the latter circumftance, and where the ftone is not prone to vitrification, much of the labour a-.d expence of breaking may be fitved, by uling an extr.i quantity of fuel, and keeping up a ftrong fire in the kiln," or place where it is burned ; the form or conftruciion of which depends partly on the quaUties and value of the mutenalf, and partly on the kinds of fuel that are made ufe of, and the L I M Ihe differences of their prices at the places where they are ■employed. Sec KiLS. It is vifeful that the procefs of burning lime fliould go on Auring January and February, as well as moll ni the winter, and aUo in the fumnuT months. Perpetual kihis are wrought in many diftricts, efpecially the northern ones, and in Ire- land ; the lime, when not taken away, heing preferved, ,in ftieds creeled for the pnrpofe, from 'h. wet. The ufual mode of managing with them is, for t\.: farmers to contraA for lome fort of meafiire, according to the cuRom or prac- tice of the particular diftridl ; being cartful that it is well burnt, and of a proper quality in other refpecis. The dif- ferences in the cxpence of burning will depend on the abun- dance or fcarcity of fuel, and the convenience of the ftoue for carriage. Li. MR, CJx, Calx viva, in the Materia Medica, &c. is prepared by breaking a pound of lime-ftone into fmall pieces, and heating it in a crucible in a very (Irong fire for an hour, or until the carbonic acid i-: entirely driven off, fo that on the addition of the acetic acid, no bubbles of gas Ihall be extricated. Lime may be made by the fame procefs from {hells previoufly wafhed in boiling water, and cleared from ey.traneons matters. In the former pharmacopeias lime was ranked among the articles of the Materia Medica, and taken as prepared for its ufes in the arts ; but in the lad London Pharmacopeia particular dircftions are given for obtaining it in a purer liatc. Two varieties of the carbonate are feletled from which it may be prepared, ij/^. lime-Hone and fliells of oylters ; the latter of which contains the leall foreign admixture ; but even the former, thus prepared, will be much purer than that which is ufiially made from chalk. According to Kn-vvan, carbonate of lime confifts of 45 parts of carbonic acid and 55 of lime : but from whatever com- bination it be obtained, lime is always the fame fubllaiicc, poflefiing the fame charatters, and producing the fame effeds, though it may be different with regard to the pro- portion of heterogeneous matters with vvhicli it is mixed ; and, therefore, the di(linftioi>s which were formerly made between its medical qualities, as obtained from different fources, were fuperfluous, and will not, in the prefent ftate of fcicnce, be likely to be renewed by the introdii
