Sec. 342. Neither are Purges without their Abuse and Danger; they determine the Course of all the Humours more violently to the tender afflicted Parts; the Body becomes exhausted; the Digestions fail; the Bowels are weakened, and sometimes even lightly ulcerated, whence incurable _Diarrhoeas_ or Purgings ensue, and prove fatal after many Years Affliction. Sec. 343. If the Evacuations prove excessive, and the Distemper tedious, the Patient is likely to fall into a Dropsy; but if this is immediately opposed, it may be removed by a regular and drying Diet, by Strengthners, by Friction and proper Exercise. __Chapter XXV.__ _Of the Itch._ __Sect.__ 344. The Itch is an infectious Disorder contracted by touching infected Persons or Cloaths, but not imbibed from the Air: So that by carefully avoiding the _Medium_, or Means of Contagion, the Disorder may be certainly escaped. Though any Part of the Body may be infested with the Itch, it commonly shews itself on the Hands, and chiefly between the Fingers. At first one or two little Pimples or Pustules appear, filled with a kind of clear Water, and excite a very disagreeable Itching. If these Pustules are broke by scratching them, the Water oozing from them infects the neighbouring Parts. At the Beginning of this Infection it can scarcely be distinguished, if a Person is not well apprized of its Nature; but in the Progress of it, the little Pustules increase both in Number and Size; and when they are opened by scratching, a loathsome kind of Scab is formed, and the Malady extends over the whole Surface. Where they continue long, they produce small Ulcers, and are at that Time highly contagious. Sec. 345. Bad Diet, particularly the Use of Salt Meat, bad unripe Fruit, and Uncleanliness occasion this Disease; though it is oftnest taken by Contagion. Some very good Physicians suppose it is never contracted otherwise; but I must take Leave to dissent, as I have certainly seen it exist without Contagion.
