For dropsy, a will boar's urine is good, taken in small doses in the patient's drink; it is of much greater efficacy, however, when it has been left to dry in the bladder of the animal. The ashes, too, of burnt cow-dung, and of bulls' dung in particular —animals that are reared in herds, I mean—are highly esteemed. This dung, the name given to which is "bolbiton,"[1] is re- duced to ashes, and taken in doses of three spoonfuls to one semisextarius of honied wine; that of the female animal being used where the patient is a woman, and that of the other sex in the case of males; a distinction about which the magicians have made a sort of grand mystery. The dung of a bull-calf is also applied topically for this disease, and ashes of burnt calves' dung are taken with seed of staphylinos,[2] in equal proportions, in wine. Goats' blood also is used, with the marrow; but it is generally thought that the blood of the he-goat is the most efficacious, when the animal has fed upon lentisk, more particularly.
