A physical treatise grounded, not upon tradition, nor phancy, but experience, consisting of three parts. The first, a manuduction, discovering the true foundation of the art of medicine. Second, an explanation of the general natures of diseases. Third, a proof of the former positions by practice. By William Russell, chymist in ordinary to His Majesty.

Of Fiery Phlegmones in general, and their Cure.

I forbear to write particular Exam∣ples of these Diseases, because they are so numerous, so frequently cured by my Method, and so certainly known to the Patients themselves; But in general the Tumors are large, the Blood (at first appearance) un∣corrupted; yet it is not long before great Pains, the Forerunners of Pu∣trefaction, discover themselves. And thô at the first manifestation of these Tumors, when only a weight and bur∣then upon the life is perceived, letting Blood doth somewhat diminish the Tumor, and prevent Pain; yet, if it have a diseasy Character, that doth not hinder the foregoing determina∣tion

of Nature towards separation; but allaying part of her fury, doth I acknowledge render the Suppurative Power less burthensome. But if Quit∣ter be begun to be made, then Nature by Phlebotomy is hindred of her own Determination; and being thereby weakened, languisheth, and labours to little purpose, making those Distem∣pers tedious in suppurating; where∣as, had not that supposed Expedient been used, Suppuration would much more speedily have followed.
