CHAP. I. Of ƲLCERS in General.
I. THEY are called in Greek, 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉, pl. 〈 in non-Latin alphabet 〉〈 in non-Latin alphabet 〉. in Latin, Ulcus, pl. Ulcera; and in English, an Ulcer, pl. Ulcers.
II. The Definition. An Ʋlcer in the Solution of Ʋnity, putrified: or thus, An Ulcer is a Wound which is putrified, and sends forth stinking and putrified Matter.
III. Barbett defines an Ulcer to be a Solution of Continuty, with Diminution of Magnitude in the soft Parts, from a cor∣roding matter.
IV. The Differences. Joel, Chirurg. de Ʋlcerib. Tom. 6. Sect. 6. Et quanquam utraque affectio, & Vulnus & Ʋlcus, continuitatis in aliqua parte sit solutio & di∣visio; differunt tamen, quod con∣tinui solutio in Vulnere ab externis causis caesim illatis cum Sanguine eruptione inferatur: Ʋlcus verò, ut plurimum ab interna causa, erodentibúsque Humoribus produci∣tur; ex quo non Sanguis, ut ex Vulnere, sed, vel sanies, vel pus, vel putrida colluvies emanat: quanquam ab externis quoque causis, ut applicatione Causticorum Remediorum, aut morsu ictuque virulentorum Auimalium, paulatim Ʋlcera excitari possunt. Here he shews us the difference between a Wound and an Ulcer. Now altho' (says he) both Wounds and Ulcers are a solution and divi∣sion of continuity in some part; yet notwithstanding they differ; for that a solution of unity in a Wound, comes from external causes, as cutting, attended with a flux of Blood: whereas an Ulcer is for the most part from an internal cause, and is induced from eroding or corrosive Hu∣mors; from which Blood comes not as in a Wound; but either
