disfiguring the Skin with cor∣roding and spreading Pustules.
III. The Causes. The Proca∣tartick Cause is taking cold, lying in cold places, eating and drinking sowr and salt Meats, and even to surfeiting and drunkenness, and persisting in even a continued surfeiting course of living, where∣by plenty of evil Humors are bred.
IV. The Antecedent Cause is Choler mixt with a putrid Lym∣pha, or with a preternatural salt Ferment in the Blood; which being by some violent action, surfeiting, or the like, stirred up into act, causes this kind of Breaking-out.
V. The Conjoined Cause, is a salt, watery, and pus-like Matter protruded out into the Cuticula.
VI. The Signs. It rises in a cluster of small Wheals, not much differing from the colour of the Skin, and are first discovered by their itching: and being rub∣bed or scratched, there issues out a thin serous Humor: or not being scratched, they swell many times to the bigness of small Tares, or great Pins-heads, which drying, they become a Scab.
VII. They many times creep up and down; and as they heal in one place, they often break out in another; being mostly of a cluster, like to Millet-seed.
VIII. The Prognosticks. There is little of danger in this Disease, unless rendred so by the unskilful use of Repellents: it is without a Fever, but is of difficult cure, especially if it is in the Face, Nose, or Ears.
IX. If it is neglected, or ill handled, it eats deep into the Flesh; and then in what part so ever it is, it is very hard to be cured, degenerating some∣times into Herpes exedens.
X. The Differences. There are three kinds of Herpes: 1. Simple, to wit, the Shingles; which tho' they proceed from Choler, or a cholerick Blood, yet they dif∣fer from the other two kinds; because these of the first sort are for the most part Critical, as coming forth after a Fever or Ague, or some other illness. See Lib. 2. Cap. 24 aforegoing.
XI. 2. The millet-like Herpes, being mostly like Millet-seed, as to bigness, which differ from the former, in the Humor causing them; and from the latter, in the form of the Tumor or Breaking-forth; and in the place first affected, which is the Cuticula.
XII. The eating Herpes, which affects the Cutis or Skin, and many times the Flesh also: this, says Sennertus, is of the nature of an ulcerated Erysipelas, from which notwithstanding it differs in the thinness of the Humor.
XIII. There are two Indica∣tions of Cure: the first, which respects the antecedent Cause; the second, which respects the conjoined.
XIV. In respect to the antece∣dent Cause; the Diet ought to be the same as in an Erysipelas, cooling and moistning, and which may attemperate Choler, and salt Phlegm.
XV. Bleeding here is not al∣lowed, but Purging is very necessary;
