Among the aphrodisiacs, we find mentioned, a wild boar's gall, applied externally; swine's marrow, taken inwardly; asses' fat, mixed with the grease of a gander and applied as a liniment; the virulent substance described by Virgil[1] as distilling from mares when covered; and the dried testes of a horse, pulverized and mixed with the drink. The right testicle, also, of an ass, is taken in a proportionate quantity of wine, or worn attached to the arm in a bracelet; or else the froth discharged by that animal after covering, collected in a piece of red cloth and enclosed in silver, as Osthanes informs us. Salpe recom- mends the genitals of this animal to be plunged seven times in boiling oil, and the corresponding parts to be well rubbed therewith. Balcon[2] says that these genitals should be reduced to ashes and taken in drink; or else the urine: that has been voided by a bull immediately after covering: lie recommends, also, that the groin should be well rubbed with earth moistened with this urine.

Mouse-dung, on the other hand, applied in the form of a liniment, acts as an antaphrodisiac. The lights of a wild boar or swine, roasted, are an effectual preservative against drunkenness; they must, however, be eaten fasting, and upon the same day. The lights of a kid, too, are productive of the same effect.
