CHAP V. How to know Symptomes.

ALthough Symptomes for the most part are obvious to the senses, * 1.1 yet somtimes they lye hid, and had need have signes, which are taken from causes, and effects: nutri∣tion, if it be not rightly performed, the body is extenuated and growes leane: if augmentation be not rightly per∣fected, the body is lesse nourished; if the generative fa∣culty be hurt, either none, or weake Children are generated; attraction and retention being hurt, are known from their effects, especially digestion is known by the excrements of its concoction; so that which is in the stomach, by the dregs of the belly; that which is in the liver and veines, by the urine; those excrements which are in the brest, by the spittle; lastly the expulsive faculty is known to be hurt, if those things are retained which ought to be ex∣pelled.

The vitall faculty is known to be hurt by the changed pulse of the heart and Arteries. * 1.2

As for the animall faculty, the Physitian knows the de∣pravation of the principall faculties from the words and deeds which are different from comlinesse and congruity. In the same manner also other animall actions may be known to be hurt from their effects.
