but somewhat differs in the Composition. In the Author it is thus: ℞ Pure and clean Filings of Mars ℥ij. Oyl of Turpentine, or Oyl of Juniper, or Aniseeds, or Fenuel, which of them you please ℥iij. mix them, and instil thereto by drops, and at times of the acid chalibeat Spirit of Sal Armo∣niack; or for want thereof, a pure Spirit of Nitre: mace∣rate them a little while, so will you have in the Oyl a rubicund Tincture, which separate from its feces by filtring, and keep for use. § 2. The acid cha∣libeat Spirit of Sal Armoni∣ack, is made from Sal Armo∣niack sublimed from an equal quantity of pure Filings of Mars, in a Glass Alimbeck, or Glazed Earthen Cucurbit, upon a naked Fire, first gentle, and then increasing it with degrees of heat, till the bottom of the Cucurbit is red hot (saving the volatile Spirit as it comes forth). ℞ This Martial Sublimate, mix it with the Caput Mort. very well, expose it to the moist Air, that it may be impregna∣ted, and begins to ascend in Flowers of a yellowish colour: put this impregnated Mass into a large Glass Retort, with a long Neck well coated; place it in a Reverberatory, on a naked Fire, with a large Re∣ceiver, well closed in the Joynt, then distil first with a gentle Fire, to force the Flegm; then with a stronger gradatim, that the Spirit in the form of Clouds may follow, by little and little, which continue till the cloudy Spirits disappear, so will you have the acid saline Spirit of Sal Ammoniack of a Golden colour, (much like to Spirit of Salt) by one only distillation pure and deflegmated. § 3. This is the Spirit which Zwel∣fer uses in making of this Balsamum Martiale, for want of which, he says, you may use Spirit of Nitre, and that our Author to avoid such a great labour, chose rather to do: however, I thought good to give the Prescript, that e∣very man may take his choice. § 4. This Balsam, says Zwel∣fer is a present Remedy a∣gainst the Stone, and Ulcers of the Reins, the Colick, the Nephritick Passion, and all other internal Ulcers, of what kind soever, healing them af∣ter a most effectual manner: Dose à ℈ss. ad ℈j. § 5. It has also the same effects upon exter∣nal Ulcers, doing more than can possible be imagined in a very short time; and there∣fore may very well be ac∣counted among the best of Vulneraries Zwelfer also makes it with Ol. Vitrioli.
