CHAP. XIX. Of Ʋlcers, and what they are.
VLcers are of divers and sundry kinds, and are ingendered of many causes, as hereafter I will shew. But first I will write of those kinds of Ulcers that are caused of Wounds. You shall understand, that wounds in what part of the body so∣ever they be, being imposthumated or cancrenated, they change their names, and are no more called wounds, although their originall was a wound. For when it is cancrenated, it is called Ʋlcera corrosiva, because it goeth eating and creeping on the flesh: but when the wound is imposthumated and full of matter, it is called Ʋlcera putrida, that is putrified, and it is because it is filthy and stinketh. But when it is neither can∣crenated, nor yet aposthumated, but that through some evill disposition the wound is closed, and that there cometh in it evill qualities without alteration, then is it called Ʋlcera sor∣dida, because therein is evill qualitie, and it appeareth but little, but it is evill to heal. There be other sorts of Ulcers also, which are caused of divers and sundry kinds of Tumours: and the most evill and mischeivious are those that are of Tumours caused of the Pox: for unto those there runne abun∣dance of evill humours that augment the Ulcer, and they be the worst sort, for they cannot be healed by themselves, except the body be well purged and evacuated of all the humours that are offensive. There is another kinde of Ulcer that cometh of an Imposthume as well hot as cold, and those are more gentle and easie to be helped, if you know the Medi∣cines that are apt to help and dissolve those kinds of Ulcers. These are the three kinds of Ulcers that commonly happen unto men and women through divers causes, as before is said, so that these are the principall causes of those maligne Ulcers.
