There are two kinds of areae. Both of them agree in this, that the surface of the skin mortifying, the hairs first decay, and then fall off; and if the part is wounded, thin and fetid blood is discharged; and both kinds increase in some people quickly, in others slowly. It is then worst, when it has rendered the skin thick and fat, and entirely smooth. That, which is called alopecia[FR], spreads in no certain form. It is found both in the hair of the head, and in the beard. But that, which from its likeness to a serpent is called ophiasis[FS], begins at the hinder part of the head; its breadth not exceeding two fingers; it creeps with two heads to the ears; in some, even to the forehead, till the two heads are joined in the fore part. The former species happens at any age; the latter commonly to infants. The first hardly ever terminates without medicine; the other often goes away of itself. [FR] ἀλωπεκία. [FS] ὀφίασις. Some scarify these kinds of areae gently with a knife. Others anoint them with escharotic medicines mixed with oil; and especially burnt paper. Others apply turpentine resin with thapsia. But nothing is better than daily shaving with a razor; because, when the cuticula is gradually cut off, the small roots of the hairs are laid bare. Nor should this be given over, till it appears, that the hair grows thick. It is sufficient to rub the part, that is frequently shaved, with copperas. CHAP. V. OF VARI, LENTICULAE, AND EPHELIDES. It is almost a folly to cure vari, lenticulae, and ephelides: but it is impossible to prevent women from being nice in what regards their beauty. Of these disorders, which I have just mentioned, vari and lenticulae are universally known; however, that species is more rare, which the Greeks call phacia[FT], though that is only of a more ruddy colour, and more unequal surface than the common lenticula. The ephelis[FU] is unknown to most people; and is nothing else than a certain ill coloured asperity and hardness. The others are peculiar to the face; the lenticulae sometimes appear in other parts, of which I did not think it worth while to treat separately elsewhere. [FT] φακία. [FU] ἐφηλὶς. But vari are well cured by the application of resin mixed with an equal quantity of scissile alum, and a little honey. Equal quantities of galbanum and nitre, beat up with vinegar to the consistence of honey, remove a lenticula. The part is to be rubbed with these, and after an interval of several hours, washed clean in the morning, and gently anointed with oil.
