CHAP. III. Of SIMPLE ƲLCERS.
I. WHAT the Greeks call 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, and the Latins Ulcus simplex, we in English call A Simple Ulcer.
II. The Kinds. Authors make two kinds of simple Ʋlcers: 1. One, where the Skin is only wanting. 2. Another, where there is a loss of Flesh also. The first is called planum, a plain Ulcer; the other cavum, a deep Ulcer. We shall consider them in the Cure but as one, for that the Cure of the former is compre∣hended in the latter.
III. Now a simple Ʋlcer, which is a solution of Ʋnity in a soft Part, with a dissolution of Magni∣tude putrified, is that which has neither a Disease, nor a Cause, nor a Symptom adjoined to it, or complicate therewith; be∣sides the solution of Unity, caused by erosion.
IV. The Kinds. The proximate, or nearest cause of an Ʋlcer is, a matter which has in it a cor∣roding quality, whether it is bred in the Body, or happens to the Body from without.
V. If this corrosive Humor is bred within the Body, it is gene∣rated either without the Part affected, or within the Part af∣fected it self: if without the Part affected, it is either a Cholerick Humor, or Atra Bilis, or Melancholy, or a salt Phlegm, or a salt, nitrous, and sharp Serum, which you may know by their particular Signs: these flowing unto any Part, may cor∣rode and exulcerate it.
VI. If the corrosive Humor is generated in the Part affected, it obtains its acrimony in the Part it self, by reason of some dis∣temper in the said Part, thro' a Blow, or Fall, or Overstraining the Part; whereby the Blood or some other Juice is extravasa∣ted; where by its long aboad and digestion, it becomes sharp, and so grows sharper and sharper, 'till it corrupts, putri∣fies, and becomes corrosive.
VII. But if its Cause hap∣pens to the Body from without, it is from septick, putrifying, or caustick Applications, whether they be Actual, or Potential. Or from Contagion; as in the Venereal Disease, Phthisis, Leprosy, Itch, &c. where the Virus or Poison is communicated by con∣tact, to the Pores of the Skin, where entring them, it exul∣cerates it, and there generates the like Disease.
VIII. The Signs. External Ʋlcers are manifest to sight and touch, so that they may be known without any other Signs: but the internal ones, which lye hidden, are known by the Probe, if way is made to search for them; or by the Excrements flowing from them, the Pain, and
