CHAP. VIII. Of things not naturall, which is the second part of Physicke.

What things not naturall are, HAving shewed you things naturall, whereof mans body is composed, and what they are, as Elements, Humours, &c. as we formerly comprehended under the name naturall; we will now proceed in the description of things not naturall, which are used to con∣serve and defend the body composed and made of the things naturall already spoken of: these doe pertaine to that of Physicke, which is for preserving health, and are the meane betwixt things naturall, and things against nature, for they doe not constitute our nature as things naturall; neither doe they hurt or damage it, as things against nature, but they are indifferent good if they be well used, and bad if they be ill used; the use whereof we consider from foure conditions, quantity, quality, occasion, and manner of using: These being observed, you may effect and cause things doubtfull of themselves to bring undoubted health; things not naturall are in number six; 1. the aire that goeth about us; 2. the meate and drinke we use; 3. the motion and rest of our bodies; 4. sleeping and waking; 5. repletion and ina∣nition, or things to be expelled, or retained, 6. and per∣turbations of the minde.
