COMMENTARY. Galen and Serapion likewise recommend the skin of a snake, when boiled in wine or vinegar, as a remedy for earache and toothache. See also Haly Abbas (Pract. ii, 49, 530.) Dioscorides gives nearly the same account of it, only he recommends the cast skin of the viper as an ophthalmic remedy. (ii, 19.) The serpent’s slough is still used medicinally in the East. See Ainslie (Materia Medica, ii, 291.) Γῆς ἔντερα, Vermes terreni, _Earthworms_, when pounded and applied to wounded nerves, have immediately the most wonderful effects. * * * * * COMMENTARY. Dioscorides says that earthworms, pounded and applied, agglutinate divided nerves, and stop tertians; that, when boiled with the grease of a goose, they cure affections of the ears when injected; that, in like manner, when boiled in oil and injected into the opposite ear, they relieve toothache; and that they promote the flow of urine when pounded and drunk in wine. (ii, 72.) Galen commends earthworms as being diuretic when drunk in must. He mentions further, that, according to the report of certain physicians, earthworms have been given internally and applied externally without burning or boiling. Of all the ancient authorities, Aëtius is the fullest on the medicinal virtues of earthworms. (ii, 168.) The Arabians do little more under this head than copy the descriptions of them given by Dioscorides, Galen, and Paulus. Avicenna recommends them, when pounded and drunk in wine, not only as being diuretic but also lithontriptic. (ii, 2, 198.) The Lumbrici terrestres, or earthworms, are described and very much commended for their medicinal virtues in Quincy’s ‘Dispensatory’ (p. 140), and Lewis’s ‘Materia Medica’ (ii, 76.) Γίγαρτα, Gigarta vinacea, _Grape-stones_, are desiccative in the second degree, but refrigerant in the first. Being, therefore, cooling, they agree with all defluxions. * * * * * COMMENTARY. Galen mentions _Grape-stones_ as sour and astringent remedies, and, therefore, applicable in all defluxions from the bowels. Avicenna recommends the ashes of grape-stones with vinegar in torsion of the nerves, and along with oil for contusion of the limbs and softening of the joints. (ii, 2, 723.) See also Rhases (l. ult. Cont. i, 745.) Γιγγίδιον, Gingidium, _Toothpick Fennel_, is possessed of no manifest heat, but is desiccative in the third degree, and astringent. It is, therefore, stomachic. * * * * * COMMENTARY. Dioscorides says of the _Daucus gingidium_, that it is a good potherb, and that as a medicine, when taken in a decoction with wine, it is diuretic and lithontriptic. (ii, 166.) Galen defines its virtues to be considerable astringency with slightly heating powers. The others treat of it in like terms. Few if any of the Arabians have noticed it. Γλαύκιον,
