CHAP. III. Of things Natural.
THat the Chirurgeon may rightly; and according to Art perform the foresaid works, he must set before is eys certain Indications of working: Otherwise, he is like to become an Em∣perick; whom no Art, no certain reason, but only a blind temerity of fortune moves to boldness and action.* 1.1 These Indications of actions are drawn from things (as they call them) natural, not-natural, and besides-nature, and their adjuncts, as it is singularly delivered of the Ancients, being men of an excellent understanding. Wherefore we will prosecute according to that order, all the speculations of this Art of ours. First therefore, things Natural are so termed, because they con∣stitute and contain the nature of mans body,* 1.2 which wholly depends of the mixture and tempera∣ment of the four first bodies, as it is shewed by Hippocrates in his Book de Natura humana: where∣fore the consideration thereof belongs to that part of Physick, which is named Physiologia; as the examination of things not natural to Diaetetice,* 1.3 or Diet, because by the use of such things it ende∣vours to retain and keep health: but Therapeutice, or the part which cures the Diseases, and all the affects besides nature, challenges the contemplation of those things which are not agreeable to nature.* 1.4 But the things which are called Natural, may be reduced to seven heads: besides which, there comes into their fellowship, those which we term, Annexed.
The seven principal heads of things Natural; are
- ...Elements
- ...Temperaments
- ...Humors
- ...Parts or members
- ...Faculties
- ...Actions
- ...Spirits.
To these are an∣nexed, as some∣what near;
- ...Age
- ...Sex
- ...Colour
- ...Cmpoosure
- ...Time or season
