THESE diseases of the mind, forasmuch as they have their chief seat and organs in the head, which are commonly repeated amongst the diseases of the head which are divers, and vary much according to their site. For in the head, as there be several parts, so there be divers grievances, which according to that division of Heurnius (which he takes out of Arculanus,) are inward or outward (to omit all others which pertain to eyes and ears, nostrils, gums, teeth, mouth, palate, tongue, wesel, chops, face, &c.) belonging properly to the brain, as baldness, falling of hair, furfaire, lice. &c. Inward belonging to the skins next to the brain, called dura and pia mater, as all head-aches, &c., or to the ventricles. caules, kels, tunicles, creeks, and parts of it, and their passions, as caro, vertigo, incubus, apoplexy, falling sickness. The diseases of the nerves, cramps, stupor, convulsions, tremor, palsy: or belonging to the excrements of the brain. catarrhs, sneezing, rheums, distillations: or else those that pertain to the substance of the brain itself, in which are conceived frenzy, lethargy, melancholy, madness, weak memory, sopor, or Coma Vigilia et vigil Coma. Out of these again I will single such as properly belong to the phantasy, or imagination, or reason itself, which Laurentius calls the diseases of the mind; and Hildesheim, morbos imaginationis, aut rationis læsæ, (diseases of the imagination, or of injured reason,) which are three or four in number, phrensy, madness, melancholy, dotage, and their kinds: as hydrophobia, lycanthropia, Chorus sancti viti, morbi dæmoniaci, (St. Vitus's dance, possession of devils,) which I will briefly touch and point at, insisting especially in this of melancholy, as more eminent than the rest, and that through all his kinds, causes, symptoms, prognostics, cures: as Lonicerus hath done de apoplexia, and many other of such particular diseases. Not that I find fault with those which have written of this subject before; as Jason Pratensis, Laurentius, Montaltus, T. Bright. &c., they have done very well in their several kinds and methods; yet that which one omits, another may haply see; that which one contracts, another may enlarge. To conclude with Scribanius, "that which they had neglected, or profunctorily handled, we may more thoroughly examine; that which is obscurely delivered in them, may be perspicuously dilated and amplified by us:" and so made more familiar and easy for every man's capacity, and the common good, which is the chief end of my discourse.
