Chap. XXIII Of a Pain in the Knees, and Its Cure
The knees are next to the hips, in which there sometimes happens to be a pain. The cure consists in the same cataplasms and cupping: which are the remedies also when any pain arises in the shoulders, or the other joints. It is most hurtful of all things for one, whose knees are pained, to ride on horseback. Now all pains of this kind, when they have continued long, are scarcely cured without the use of the actual cautery.
