wax mixed with four parts of rose-oil, prepared from the oil of unripe olives without salts, the ingredients being pounded in a mortar, and as much cold water poured in as it can receive. But if you add a little thin and transparent vinegar, you will render the medicine still better: but polenta, with some of the aforementioned cooling herbs, cool very properly, and fat dates with any of them. And the part may be anointed with ceruse, Cimolian, or potter’s earth, with the juice of strychnos, or litharge with rose-oil, or chalcitis with oil and must; or ceruse, with vinegar and buckthorn; or acacia, with vinegar. When the effervescence subsides we may use these simple applications, native sulphur and mint, with vinegar and rose-oil; or rue with worm-wood; vinegar and oil, or litharge with the juice of leeks and beet; or compound ones, as this trochisk, more especially to the head: of litharge, of ceruse, of saffron, of native sulphur, of opium with must; and in common, for all parts, of Sinopic vermilion, of chalcitis, of roasted misy, of verdigris, of copperas, of fissile alum equal parts, use with vinegar.—_Another_: Of native sulphur, of ceruse, of opium, of acacia equal parts; use with vinegar. A cataplasm for erysipelas, herpes, abscess, parotis, and burning: of the tender leaves of fresh marsh-mallows, lb. j; having boiled in water and oil, triturate properly, and adding of rose-oil, oz. iv; of litharge, of ceruse, of each, oz. iiss; triturate again with the juice of coriander, or of house-leek, or of strychnos, then adding crumbs of bread so as to form a plaster, apply it. And use this plaster: of oleum cicinum, i. e. castor-oil, lb. j; of oil of myrrh, lb. j; of wax, oz. v; of litharge, oz. iv; of scraped verdigris, oz. ij; the verdigris and litharge are to be triturated with vinegar. A cerate for erysipelas and burns: of white wax, oz. iv; of rose-oil, oz. iij; six eggs, of pellitory of the wall, oz. iv. When the inflammation ceases or becomes chronic, before the part becomes livid, apply a cataplasm of raw barley-meal; but if it has already become livid, incisions must be made in the part, and cataplasms moreover applied, and hot sweet water poured on it, and sometimes sea-water or brine; and sometimes these ingredients are to be mixed with the cataplasm, and then we must use the aforesaid compound medicines with caution: for should these symptoms continue, a transition to suppuration or mortification takes place. * * * * *
