that ascribed to Amythaon, and those which we are about to describe for scrofula. * * * * * COMMENTARY. See Galen (De Tumoribus; Meth. Med. xiv; Therap. ad Glauc. ii); Oribasius (Synops. vii, 34); Aëtius (xv, 3, 4); Leo (vii, 4); Actuarius (Meth. Med. iv, 16); Serapion (v, 23); Avicenna (iv, 3, 2, 12); Haly Abbas (Pract. iii, 31); Alsaharavius (xxix, 1, 15); Rhases (Antid. i, Cont. xxvii, Antidot. i.) This section is entirely taken from Galen (Ther. ad Glauc. l. c.) Galen’s account, however, is somewhat fuller than our author’s, and contains a case treated upon the principles which he lays down. It was a case of hard swelling in the thigh, arising from an erysipelas which had been improperly treated by astringent and cooling applications. Galen informs us that he began by pouring upon the limb an attenuant oil, namely, the Sabine; after which he caused it to be rubbed with marrows and fats medicated with bdellium, mastich, ammoniac perfume, and the like. After this he bathed the whole limb with a solution of ammoniac in very acrid vinegar. When the swelling had been lessened, but not completely removed by these means, he afterwards applied one of the pitch medicines, and at length effected a cure. In another place he states that scirrhus is sometimes allied to cancer. Oribasius likewise recommends a combination of emollients with discutients; and Actuarius approves of the same practice. Aëtius has a valuable chapter upon this subject. Besides the articles mentioned by our author, he recommends various rosins, turpentine, frankincense, and the like. He forbids the use of aluminous, sulphureous, and chalybeate baths. For indurations of tendons he recommends things possessed of attenuant and cutting properties combined with emollients, such as ammoniac dissolved in vinegar with melons. The Arabians treat of scirrhus in much the same terms as the Greeks. Avicenna properly directs us to bleed when there is congestion of black blood in the part, and afterwards to use applications of a solvent and emollient nature. He and Serapion mention the same identical remedies as those of Paulus. For dissolving hard tumours he recommends an oil containing fenugreek, cyperus, and aromatic reed. Haly Abbas ascribes the formation of scirrhus to the same causes as our author, and recommends relaxant and emollient applications. Alsaharavius directs us to procure evacuations of black bile, and gives prescriptions for various emollient and discutient applications. When the usual remedies do not succeed, he advises recourse to be had to the operation. Rhases divides scirrhus into two varieties, that accompanied with sensibility, and that which is insensible. He mentions that Antyllus approved of extirpation and the actual cautery when the disease is of a corroding and cancerous nature. SECT. XXXIII.—ON STRUMA OR SCROFULA.
