It appears from the works of Fabricius of Aquapendente, that the practice of treating atheroma and meliceris by septic applications was sufficiently common in his time. Andreas Laurentius approves of removing _scrofulous tumours_ in this way when they are deep-seated and have a broad base. He thus enumerates the septics used in his age: “Secundo extrahi potest struma caustico, nunc affixo in ejus medio candente ferro, nunc admotis erodentibus et putrefacientibus ut sandaraca, arsenico, argento liquido usto, oleo quod ex atramento sutorio igne elicitur, calce non extincta cum sapone, axungia porcina cum argenti sublimati portiuncula, pulvere mercurii, erinaceorum cumbustorum, testæ sæpiæ, auripigmenti.” He also recommends us to tie the base of the tumour with a thread wet in a solution of arsenic (De strum. nat.) The treatment of atheroma by caustics is well described in the ‘Bibliotheca Chirurgica’ of Manget. SECT. XXXV.—OF FAVI. The favus is a swelling on the skin, having perforations through which a honey-like fluid is discharged. Wherefore dried grapes with rue are to be applied to it; or, the tender leaves of the fig tree with honey; or, cresses with linseed in honey; or, the root of the garden cucumber with honey; or, sulphur vivum with cerate or turpentine. You may vary the treatment of favi by transferring hither what is said in the Third Book regarding achores. * * * * * COMMENTARY. Alexander states that the favus resembles the achores, differing from them solely in magnitude: for the openings of the pores by which the fluid escapes resemble the combs of bees, whence it takes it appellation; but in achores we cannot see the pores by which the fluid issues. Aëtius gives a similar description of the complaint, which, he says, mostly attacks muscular parts, as the limbs, soles of the feet, over the sixth vertebra of the neck, and the sides. When it attacks the head, he says, it sometimes spreads to the skull. In this case he directs us to treat it with acrid applications, and even the actual cautery. For incipient favus he recommends an application consisting of sulphur, barley flour and meal. Nonnus recommends the following application: of litharge, dr. ij; of alum, dr. iij; of the leaves of rue, dr. ij; of wine and rose-oil, q. s.
