CANTHARIDIN, in Chemijlry, a name given by Dr. 

 Thomfon to a pecoliar principle extrafted from cantharides 

 in tlie following manner. 



Boil cantharides in water till e\'ery thing foluble in that 

 liquid be taken up. Concentrate the folution by evapora- 

 tion, and when reduced to a thick fyrup, boil it repeatedly 

 in alcohol, till that fluid ceafes to aft upon it. Evaporate 

 the alcoholic folution to drynefs, and digeft the dry refidue 

 in fulphuric ether. When the ether has affumed a yellow 

 colour decant it, and expofe it in an open veffel to fpon- 

 taneous evaporation. Small cryflalline plates mixed with 

 yellow matter will foon feparate. The yellow matter may be 

 feparated by alcohol, which leaves the cryftals of cantharidin 

 quite pure. 



Cantharidin thus obtained exifts in the form of (hining 

 micaceous plates. It is infoluble in water, and in cold 

 alcohol. Boiling alcohol diflblves it, but the cantharidin 

 again feparates on the cooling of the alcohol. Ether dif- 

 folves it, but not in large quantities. It readily difTolves in

oils, and when applied to tlie fkin, afts as a veficatoiy with 

 great energy. The folution of it in oils is equally effica- 

 cious. This principle feems to have been firft feparated by 

 Thouvenel. See Cantharides. 



CANTHARIS, 1. ult. deli which fee refpeftively. 

 One of the moft elegant infefts of this genus is the fcarlet 

 cantharis ; entirely of a vivid red, except the body, legs, 

 and antenns, which are coal-black. It is fomewhat more 

 than half an inch in length. The C. bipuftulata i« a beau- 

 tiful infeft, fomewhat fmaller than the preceding, of a very 

 dark but elegant gilded green, with the tips of the wing- 

 fhells red, and on each fide of the thorax a triple veficle of 

 a bright red colour, capable of extenfion or retraftion at 

 the infeft's pleafure, and by the microfcope exhibiting an 

 alternate inflation and contraftion, like that of the luntrs in 

 the larger animals. This fpecies is found in the middle of 

 fummer on various plants, and particularly on nettles. Shaw

Cantox, in China, 1. 17, after houfes, infert built of 



brick. Col. 2, 1. I, add — Thefe/ara/idncj, as they are called, 

 accommodate, at the very lowell computation, 40,000 

 people: 1. 13, after 40,000, add — The accounts of the 

 population of Canton are very various and contradiftory. 

 The exaggerated ftatement above given is that of Le 

 Comte. Du Halde eftimates it at a miUion ; and Sonnerat, 

 erring in the other extreme, reduces the number to 75,000. 

 But according to data, collefted by captain King, in 

 "Cook's Third Voyage," (vol. iii. ) he apprehends, that 

 the city and fuburbs may probably contain about 1 50,000. 

 CAOUTCHOUC, in Chemiftry. In addition to what 

 has been faid of this fmgular fubftancc, we may obferve 

 that it has been lately flated to exift in a great variety of 

 plants, though it has been hitherto ufuaUy confounded with 

 other fnbilances. It may be feparated from refins by means 

 of alcohol. It may be extrafted from the diflferent fpecies 

 of mifletoe by water, with which it readily combines, whilft 

 in that fluid ftate in which it exifts in thefe plants. When 

 mixed with gum or extractive, it may be feparated by 

 digefting a part of the plant containing it, firft in water, and 

 then in alcohol, till all the fubftanccs loluble in thefe liquids 

 be extrafted. The refiduum is then to be dried and digefted 

 in four times its weight of reftified petroleum. Exprefs 

 the liquid part by fqueezing the fubftance in a linen cloth. 

 The liquid is then to be put by for fome days to fettle, and 

 after the clear part has been poured off, the remainder is to 

 be mixed with a third part of water, and diftilled. The 

 caoutchouc remains behind. 



According to Bucholz, a confiderable proportion of 

 caoutchouc exifts in opium. Maftic alfo is ftated to contain 

 a fubftance very fimilar to caoutchouc. 



CAPELAT, or Capeli.at, a name fometimes given by 

 farriers to a fwelling of a wenny kind, which grows on the 

 hock of a horfe, and on the point of its elbow. It often 

 arifes from bruifes, and in this cafe (hould be bathed with 

 hot vinegar and alum ; but when they grow gradually on 

 both heel's and elbow, blood is cxtravalated. AVhen this 

 happens, fuppuration (hould be promoted by rubbing the 

 part with ftimulating unguents ; and when matter is formed, 

 the tkin Ibould be opened with a lancet, in more dependent
