3 These then are the things to be done by those, who, being in health, have cause merely to be apprehensive. Now there follows the treatment of fevers, a class of disease which both affects the body as a whole, and is exceedingly common. Of fevers, one is quotidian, another tertian, a third quartan. At times certain fevers recur in even longer cycles, but that is seldom. In the former varieties both the diseases and their medicines are of various kinds.

Now quartan fevers have the simpler characteristics. Nearly always they begin with shivering, then heat breaks out, and the fever having ended, there are two days free; this on the fourth day it recurs.

But of tertian fevers there are two classes. The one, beginning and desisting in the same way as a quartan, has merely this distinction, that it affords one day free, and recurs on the third day. The other is far more pernicious; and it does indeed recur on the third day, yet out of forty-eight hours, about thirty-six, sometimes less, sometimes more, are in fact occupied by the paroxysm, nor does the fever entirely cease in the remission, but it only becomes less violent. This class most practitioners term hemitritaion.
