CHAP. XXVI. Of Ʋlcers that come in the Breast and Shoulders, and in the Back and Belly.

ULcers that come in the foresaid parts, are all caused of Imposthumes of evill qualities, that have not been well healed of the Chirurgians, which knew not how to re∣move the cause, and by that meanes the Imposthumes are be∣come malign Ulcers. He therefore that will cure these Ulcers, it shall be necessarie for him to do that which was not done; that is, to remove the cause first, and then the cure will fol∣low with more ease and speed, so there be good regard and consideration had thereof. And yet amongst Ulcers there is one kind that will receive no curation, and they are called Cancri, that are crude and of evill digestion, and go creep∣ing along the flesh, and have a root as it were a Plant: And for those kinds there is found no better remedie to mit∣tigate them, then is our Quinta essentia Vegitabile, for if you put it therein, and lay a cloth wet in the same thereon, it ta∣keth away the pain, in such sort, that it is to be wondered at, and will not suffer it to putrifie; it taketh away the stinking, and comforteth the place very much. As concerning the other kind of Ulcer, you must first find out the cause before you can help it, and the cause being found, the cure is easie to find and sure. He therefore that will be diligent, shall not

onely heal those kindes of Ulcers, but also all other Ul∣cers.
