IF the head be suddenly seized with pain from a temporary cause, even if it should endure for several days, the disease is called Cephalalgia. But if the disease be protracted for a long time, and with long and frequent periods, or if greater and more untractable symptoms supervene, we call it Cephalæa.

There are infinite varieties of it; for, in certain cases, the pain is incessant and slight, but not intermittent; but in others it returns periodically, as in quotidian fevers, or in those which have exacerbations every alternate day: in others it continues from sunset to noon, and then completely ceases; or from noon to evening, or still further into night; this period is not much protracted. And in certain cases the whole head is pained; and the pain is sometimes on the right and sometimes on the left side, or the forehead, or the bregma; and these may all occur the same day in a random manner.
