The Primitive Cause may be prevented by avoiding the Falls, Blows, or other Hurts, and the Antecedent by diminishing the Plethory of the Blood, and cooling the whole Mass by Phlebotomy. The Conjunct Cause, which is the overflowing of the Blood, may be also remov'd in dispersing it by dissolving, or else in discharging it by Suppuration. _What is a _Crisis_?_ It is a sudden setling of Humours, which happens in Diseases, whereby they are usually terminated. _How are these Critical Setlings effected?_ By the Strength of Nature, which either expels the peccant Humours thro' the Belly, or carries them to the Habitude of the Body; for in the former she causeth Fluxes of Humours, Urine and Blood; as in the other she excites Sweatings, Tumours, and even a Gangrene it self. _In what Parts do the Critical Tumours usually arise?_ {104} In the Glandules, which the Ancients call'd the _Emunctories_ of the Brain, Heart, and Liver; for they gave the Name of Emunctories of the Brain to the thick Glandules which lie under the Ears, that of the Emunctories of the Heart to those that are under the Arm-Pits; and that of the Emunctories of the Liver to those under the Groin. Now Malignant Tumours may arise in all these parts, but the Venereal happen only in the Groin. * * * * * CHAP. III. _Of Natural Tumours._ * * * * * ARTICLE I. _Of the _Phlegmon_ and its Dependancies._ _What is a _Phlegmon_?_ It is a red Tumour occasion'd by the Blood diffus'd in some part, wherein it causeth extension, pain, and heat with beating. _Are_ Aneurisms _and_ Varices, _which are Tumours, made by the Blood, to be reckon'd among the_ Phlegmons? No, because the Blood that forms the _Aneurisms_ and _Varices_ is not extravasated nor accompany'd with Inflammation, but only a Tumour of Blood proceeding from the Dilatation of the Arteries and Veins. {105} _May _Echymoses_ or Contusions consisting of extravasated Blood, be esteem'd as _Phlegmons_?_ By no means, in regard that it is not sufficient that the Blood be extravasated for the producing of a _Phlegmon_; it must also cause Pain, Heat, and a Beating, with Inflammation, which is not to be found in the _Echymoses_, except in great ones, after they have been neglected for a long time; where the corrupted Blood ought to be let out immediately, to prevent the Inflammation, overmuch Suppuration, and many other ill Consequences. _Is the _Phlegmon_ always compos'd of pure Blood?_ No, it may happen sometimes to partake of Choler, Phlegm, or Melancholy; on which account it is nam'd an _Erysipelatous_, _Oedomatous_, or _Scirrhous Phlegmon_, always retaining the Name of the predominant Humour, which is the Blood; and so of the others.
