C H A P. LV. 



Of Ulcers. 



ALL Sores that have any evil Quality ingendered in 

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

 termed tJIcers j and thefe are dillinguifhed according to 

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

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

 deep, and are therefore termed cavernous or fiilulous, which 

 Names are borrowed from their Figure. The fuperficial 

 Ulcers are divers, and attended with divers Qualities, fome 

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

 cadaverous and Carrion-like Srrjeli, from whence they are 

 alfo call'd putrid ; others are fungous, and have Excrefcences 

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

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

 Bottom of a livid or duskifli Colour, full of little Papilla 

 and UnevennelTes. The cavernous and fi- j ^ i t-M 

 Itulous are alfo ftiflinguilh'd from each other, ^^^ Ukers are 

 the cavernous being deep and broad at bot- dijiinguijh'd, 

 torn, full of little Hoks, with a fmall and 

 narrow Orifice, from whence there continually ifllieth a 

 virulent corrolive Matter ; whereas the liftulous Ulcers 

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

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

 callous and hard, and the Matter fometimes corrolive, and 

 fometimes not. There are other Sorts of Ulcers taken 

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

 corrolive, ^V. but the lirft is feldom or never to be feen in 

 Brutes, ar>d the lait 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 molt 

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

 or lefs malignant. 



Ulcers are alio diftinguifti'd, with refpedl to their Caufes, 

 %yhence 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, ox other Eruptions and Breakings out of 

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

 aad others from a vicious Difpofition in the Blood. 



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

 ready faid of their feveral Kinds; we (hall therefore make 

 fome lew Obfcrvauoris concerning their Prognofticks.
