Ulcerations of the mouth are cured by an application of brine in which mænæ[239] have been pickled, in combination with calcined heads of the fish, and honey. For the cure of scrofula, it is a good plan to prick the sores with the small bone that is found in the tail of the fish known as the sea-frog;[240] care being taken to avoid making a wound, and to repeat the operation daily, until a perfect cure is effected. The same property, too, belongs to the sting of the pastinaca, and to the sea-hare, applied topically to the sores: but in both cases due care must be taken to remove them in an instant. Shells of sea-urchins are bruised, also, and applied with vinegar; shells also of sea-scolopendræ,[241] applied with honey; and river-crabs pounded or calcined, and applied with honey. Bones, too, of the sæpia, triturated and applied with stale axle-grease, are marvellously useful for this purpose. This last preparation is used, also, for the cure of imposthumes of the parotid glands; a purpose for which the liver of the sea-fish known as the “saurus”[242] is employed. Nay, even more than this, fragments of earthen vessels in which salt fish have been kept are pounded with stale axle-grease, and applied to scrofulous sores and imposthumes of the parotid glands; as also calcined murex, incorporated with oil. Stiffness in the neck is allayed by taking what are known as sea-lice,[243] in doses of one drachma in drink, taking castoreum[244] mixed with pepper in honied wine, or making a decoction of frogs in oil and salt, and taking the liquor. Opisthotony, too, and tetanus are treated in a similar manner; and spasms, with the addition of pepper. Ashes of burnt heads of salted mænæ are applied externally, with honey, for the cure of quinsy; as also a decoction of frogs, boiled in vinegar, a preparation which is equally good for affections of the tonsillary glands. River-crabs, pounded, one to each hemina of water, are used as a gargle for the cure of quinsy; or else they are taken with wine and hot water. Garum,[245] put beneath the uvula with a spoon, effectually cures diseases of that part. The silurus,[246] used as food, either fresh or salted, improves the voice.
