the help of a more piercing and active body.
§ 13. In making of this Magistery there is a conside∣rable augmentation of the Bismuth, but this proceeds from part of the Spirit of Ni∣tre remaining in it, and which cannot be separated by the precipitation nor lotion, tho' never so often repeated.
§ 14. And what we have here taught you from Bis∣muth, or the Marcasite of Load, or Silver, as some call it, the same you may do from Zinck, or the Marcasite of Gold, which much resembles Bismuth; and the operation is performed in like manner in all respects: But in the whole operation avoid the use of AF. (made with Vi∣triol) for that, by reason of the Vitriol, will blacken or foul the Precipitate, do what you can.
§ 15. Modus Ʋtendi. You may mix ʒj. of this Magi∣stery with Orange-flower-water or Damask-rose-water ℥iv. Or with choice Pomatum, or well-washed Hogs-Lard ℥i. It sof∣tens the Skin very much, and is also good against the Itch, because it feeds upon those Acids or Salts which cause and nourish this Disease.
§ 16. Le Febur makes it thus: ℞ A. F. made of equal parts of Nitre and common Salt, lbss. Bismuth in pouder ℥iv. mix and dissolve, and if there be any foulness in it, filter it, then precipitate with tar∣tarized S. V. abstract the Li∣quor swimming above the Ma∣gistery, and wash it with di∣stilled Rain-water, till it is sufficiently dulcified. Thus Schroder and Beguinus.
§ 17. It is, says he, a very good Remedy for all the Vices and Eruptions of the Skin, and above all against the Itch: It takes away Spots and Freckles in it, and smooths the roughness of the Face and Hands: But if you would make there with a pure and white Cosmetick, and use it either with or without Pomatum, he advises to precipitate with Oyl of Vi∣triol, (tho' I think Oyl of Sul∣phur would be better) so (says he) you shall have an almost incomparable White, which you must dulcifie, dry; and keep for use.
§ 18. Charras makes it in all respects, as does Le Febur, in a large Glass Cu∣curbit, but with this diffe∣rence. That whereas Le Febur allows for the Bismuth, but p. ij. Charras allows the full tripple quantity, and then when the dissolution is perfected, precipi∣tates with the best tartarized
