CHAP. III. Of things Naturall.
THat the Chirurgion may rightly and according to Art, performe the fore-said workes, he must set before his eyes certaine Indications of working: O∣therwise he is like to become an Empericke, whom no Art, no certaine rea∣son, but onely a blind temerity of fortune moves to boldnesse and action. These In∣dications * 1.1 of actions are drawne from things (as they call them) naturall, not naturall, and besides nature, and their adjuncts, as it is singularly delivered of the Ancients, be∣ing men of an excellent understanding. Wherefore we will prosecute according to that order, all the speculation of this Art of ours. First therefore things naturall are so termed, because they constitute and containe the nature of mans body, which wholy * 1.2 depends of the mixture and temperament of the 4. first bodies, as it is shewed by Hip∣pocrates in his Booke de Natura humana: wherefore the consideration thereof belongs to that part of Physicke which is named Physiologia; as the examination of things not naturall to Diaetetice, or Diet, because by the use of such things it indeavours to retaine and keepe health: but Therapeutice or the part which cures the diseases, and all the * 1.3 affects besides nature, challenges the contemplation of those things which are not a∣greeable to nature. But the things which are called naturall may be reduced to seven heads: besides which there comes into their fellowship, those which wee terme annexed.
The seven prin∣cipall heads of things naturall are,
- Elements.
- Temperaments.
- Humors.
- Parts or members.
- Faculties.
- Actions.
- Spirits.
- Age.
- Sexe.
- Colour.
- Composure.
- Time or season.
- Region.
- Vocation of life.
