firft who mentioned the philofopher's ftonc, and though 

 that was tlu: leading objetl of his lefearches, together with 

 thf fancied panacea, or univerfal remedy ; yet he maintained 

 that cliemillry was only to be acquired, and thofc objcfts to 

 be obtained by a feries cf experiments ; and that the art 

 was not to be tauglit by words. Boerhaave fays ef the 

 clicmical works extant in Lully's name, liiat he has pcrufcd 

 mod of them, and linds them beyond all expedalion excel- 

 lent ; fo that he lias been tempted to doubt whether they 

 could be the work, of that ap;e. " So fnll," fiys he, " are 

 they of the experiments and obfervations which recur in later 

 writers, that either they muil be iuijpoiitilious, or the an- 

 cient chcmifts muft. have been acq^iiainted with many things 

 which pals for modern difcoveries." 



Lully has alio been celebrated as a fcUoIaflic mctajihy- 

 fician. He introduced into the fchooh a " new tranfccndant 

 art," which was dilhngnifhed by his name, and by means of 

 which a perfon miglii hold a difputation for a whole day, 

 upon any fiibjeft whatever, without underftanding any thing 

 of the matter. This invention fuited the genius of the age'. 

 It conlided in collefting a number of general terms, com- 

 ir.on to all the feicnccs, of which an alphabetical table was 

 to be provided. Subjefts and predicates taken from thcfe 

 were to be refpeftively infcribed in angular Ipaces upon cir- 

 cular papers. The effences, qualities, afFeCHons, and rela- 

 tions of things being thus mechanically brought together, 

 the circular papers of fubjefts were fixed in a frame, and 

 thofe of predicates were to placed upon them as to move 

 freely, and in their revolutions to produce various combi- 

 ne; icns of fubjects and predicates, whence would arife defi- 

 nitions, axioms, and propofitions, varying infinitely. This 

 contrivance, worthy of Laputa, was greatly admired in its 

 time, and its author acquired the title of the mojl enlightened 

 donor. 



The following are the titles of thofe of his works which 

 re'ate to chemillry : " De Secretis Naturae, feu de Quinta 

 juTentia, Libellus," firft printed in 1518, 4to. and frequently 

 republiflied ; " Apertorium de veri Lapidis compofitione," 

 1^46; " Teflamentum duobus Libris univerfam Artem 

 Cliemicam compleftens. Item ejufdem Compendium animx 

 tranfmutatioms Artis metallorum," 1566 ; " Liber Mer- 

 cr.norum;" " De Arte brevi ;" " Secreta Secretorum ;" 

 «' Codicillus, feu Vade Mecum, in quo fontes Alchymicas 

 Artis ct Philofophicx rcconditioris uberrime traduntur." 

 Mriny manufcript cffays of Lully are preferved in the library 

 at Leydcn, and upwards of a hundred, it is faid, which have 

 never been publifhed, in that of Venice. A complete edi- 

 tion of all the writings attr?buted to this author was pub- 

 liihed at Mayence in 1714, including treatifes on theology, 

 irorals, medicine, chemiftry, phyfics, law, &c. Gen. Biog.

 Coanza, fortified by the Portuguefe. 



LULWORTH, East, a parifli in the hundred of Win- 

 frith, in Blandford diviuon of Dorfctfhire, England, is fituated 

 fix miles from Wareham, and I16 from London, and con- 

 tains 74 houfes and 364 inhabitants. The chief objcil 



v.-orthy of notice here is Lulvvorth caftle, the feat of 



Weld, efq. It is fituated in the fouth-eaft. corner of an 

 extenfive park, which occupies a circuit of nearly four miles 

 and a half, and has been lately furrounded by an excellent 

 ftone wvl, upwards of eight feet high. The prefent edi- 

 fice, which was built on or near the fcite of a caftle men- 

 tioned fo far back as the year 1146, was commenced in 

 1588, and £ni(hed in 1 609, except the iBternal decorations. 



wliich were not completed till after the- year 1641, when 

 the ancellor of the late owner purchafed the'ellate. The 

 caille is an exaft cube of eighty feet, with a round tower 

 at each corner thirty feet in diameter, and rifing lixtccn feet 

 above the walls, which, as well as the towers, are embattled. 

 The hall and dining-room are fpacions, and the rooms in 

 general eighteen feet high. The pnncipal front is on the 

 call, and is faced with Chilmark llone, decorated with ila- 

 tuary. In the year 1789, during their majellies' rcfidence 

 at Weymouth, Mr. Weld had fevi-ral roval nfits, the par- 

 ticulars of which are recorded in two inlcriptions over the 

 entrance to the caftle. Mr. Weld has lately erected an 

 elegant little chapel for the convenience of his family ; this 

 ftrufture is of a circular form, increafcd by four fettions of 

 a circle, fo as to form a crofs, and finiihed with a dome and 

 lantern. 'J 'he parifli church of St. Andrew (which was an 

 ancient aud curious fabric) has been recently rebuilt at the 

 expence of Mr. Weld. 



United with_the foregoing parifli, and about a mile diftant 

 towards the fea, is that of Weft Lulworth, which contains 

 •J^ houfes and 312 inhi-rfjitants. At a finall diiUnce is Lul- 

 worth Cove, a fort of natural bafin, into which the fea flows 

 through a wide gap in the cliff, fufficient for the entrance of 

 veffels of 70 or 80 tons burthen. About a mile from tha 

 eove is the Arched Rock, which projects from the land into 

 the fea, having an opening near 20 feel high in ti.e middkv 

 formcd like an arch, through which the profpedl of the fea 

 has a peculiar effett. Beauties of England and Wales,

LUMBAGO, in Medicine, fignifies a pain in the loins 

 [lurnbt), efpccially from rheumatiim, affecting the ligaments 

 of the fpine, or the mufclcs of the back. See RiiEL'MA- 



TL'iM. 



The only difeafes which are liable to be miftaken fcr 

 lumbago in general, are painful affeftions cf the kidnies, 

 which, it is we'l known, are feated within the lumbar re- 

 gion on each fide of the fpine ; efpeeially inflammation of 

 thefe glands, or the formation of calculi in them, or the 

 paiTage of thefe concretions through the ureters towards 

 the bladder. The fymptoms, attendant upon thefe difor- 

 ders of the kidnies, will be found defcnbed in. their proper 

 places. (See ^s'ephralgia, Nki'hritis, and Gravel.) 

 We may obferve here, that, in lumbago, the pain docs not 

 follow the courfe of the ureters, it is not accompanied with 

 retraction of the tefticle in men, it is not increafcd by ex- 

 ternal preffure, it is often little felt, except in the eredl 

 pofture, and there is no vonviting, nor any cliange in the 

 quantity or quality of the urine ; the contrary of all \n Inch 

 is obferved in ii'.fiammatory and calculous afi^edions of the 

 kidnies. 



The internal remedies, commonly adminifteredfor the cure 

 of other forms of rheumatifm, are alfo beneficial in the lum- 

 bago ; fucli as opiates, with antinionials and other fudorificf, 

 taken at bed-time, and followed by laxatives in the morning, 

 or combined with laxatives, efpccially the fubmuriace of 

 mercury, preparations of fulphur, or falts. Much relief, 

 however, is afforded by the application of local llimulants 

 to the lumbar region externally. Liniments of camphor, 

 turpentine, and fimilar fiibfl-.nccs, have been found from the 

 experiments of Dr. Home, Dr. Fcrriar, and others, among 

 the moft efficaciotis of thefe applicacions. Dr. Fcrriar 

 affirms, that he has found a fohition of camphor infiilpliuric 

 ether relieve the pains of difeafed joints, r.fter all other
