COMMENTARY. All the authorities, including the older and the more recent, are agreed that it is a species of _Ferula_; and we are inclined to think that it was the _communis_, more especially as its medicinal powers agree well with those assigned to the article in question by Dioscorides. (Compare the latter, Mat. Med. iii, 81, with Gray’s Supplement to the Pharmacop. 80.) Dioscorides says, the pith of it, while green, relieves spitting of blood and cæliac affections, and is given with wine to persons bitten by vipers, and restrains bleeding from the nose when introduced as a tent; that the seed relieves tormina, and produces sweating when rubbed in with oil, but that its stems induce headache, and are prepared for pickles. (Ibid.) Our author borrows almost word for word from Galen. We have not been able to discover it in the Materia Medica of the Arabians, but can scarcely believe that it had been wholly overlooked by them. Ebn Baithar, in fact, under the head of _Kana_, sets down the descriptions of the _Narthex_ given by Dioscorides and Galen. Νάρκη θαλασσίη, Torpedo; when applied to the head, while still alive, in cases of headache, it procures relief to the pain, probably by its peculiar property of producing torpor; and the oil in which the living animal has been boiled, when rubbed in, allays the most violent pains of the joints. It is said to remedy prolapsus ani when applied. * * * * * COMMENTARY. Without doubt it is the _Raia Torpedo_, L., or Cramp-fish. See Artedi (Ichthy.) Frequent mention is made of this fish in the works of the ancient writers on Natural History. See in particular the poetical descriptions of Claudian (Idyll.) and Oppian (Halieut, ii.) Galen repeatedly speculates on the nature of the singular power which it possesses of stupefying every animal which touches it. He denies that it has any narcotic effect as a medicine, unless when applied alive. (De Simpl. vii.) Serapion copies his account of it. His translator renders it _Piscis stupefaciens_. (c. 437.) See Haly Abbas (Pract. ii, 49, 533.) Averrhoes compares its narcotic powers to magnetism. (Collig. v.) We have given some account of its application in this way elsewhere. See Book III, 6. Νάρκισσος, Narcissus, _Daffodil_; its root is possessed of desiccative powers so as to agglutinate large wounds, even to the division of tendons. It is also somewhat detergent and epispastic. * * * * *
