CHAP. LV. 

 Of Ulcers. 



A L L Sores that have any evil Quality Ing^ndered in 

 "^ them, fo as to hinder the Re- union of the Parts, are 

 term'd Ulcers ; and thefe are diftinguifhed according to 

 their Size, Situation, ot Degree of Malignity ; fome are fu- 

 perficial, and only appear on the outward Parts ; others are 

 deep, and are therefore term'd cavernous or fiftulous, which 

 Names are borrowed from their Figure. The fuperficial 

 Ulcers are divers, and attended with divers Qualities, fome 

 being foft and crufty, fending forth a vifcid Matter of a 

 cadaverous and Carrion-like Smell, from whence they are 

 alfo caird putrid ; others are fungous, and have Excrefcences 

 appearing in divers Afpefts ; and fome have hard and fchir- 

 rous Edges, which in Horfes, are very thick, having their 

 Bottom ot a livid or duskifli Colour, full of little PapilliS 

 and Unevennelles. The cavernous and fi- r u t jut 

 ftulous are alfo fliftinguilh'd from each other, nerlJUer$ are 

 the cavernous being deep and broad at bot- difiin?uijh''d. 

 tOm, full of little Holes, with a fmall and 

 narrow Orifice, from whence there continually iflueth a 

 virulent corrofive Matter ; whereas the fiftulous Ulcers 

 have long, ftrait, and deep Holes, which fometimes com- 

 municate with one another like a Coney- burrow, their Sides 

 cJillous and hard, and the Matter fometimes corrofive, and 

 fometimes not. There are cfther Sorts of Ulcers taken 

 Notice of by the Writers of Surgery, as the cancerous, 

 corrofive, l5c. but the firft is feldom or never to be feen in 

 Brutes, and the lalt feems not to be a proper Name of Di- 

 ftindion tor any particular Kind of Ulcer, that being an 

 evil Quality, which is more or lefs to be met with in moit 

 Ulcers, and by which they may be look'd upon to be more 

 or lefs malignant. 



Ulcers are alio diftinguifli'd, with refped to their Caufes, 

 whence fome are called primitive, and others degenerate ; 

 but it is fufficient for the underftanding this Matter, to know, 

 that all Ulcers take their Origin immediately from Wounds, 

 Bruifes, Tumors, or other Eruptions and Breakings out of 

 the Skin, fome of which turn Ulcers by ill Management, 

 aiid others from a vicious Dii'pofition in the Blood. 



■ As to the Signs, they are manifeft from what has been al- 

 ready faid of their feveral Kinds; we fhall therefore make 

 fome few Obfervations concerning their Prognofticks,
