Salmon.] § 1. In a word (says Le Mort) the Flowers of Bismuth, Znick, &c. are made exactly in the same manner as Flowers of Antimo∣ny; but you have another way of preparing the Flow∣ers in our London Dispensa∣tory, Lib. 3. Cap. 10. Sect. 11. according to Schroder's Me∣thod.
§ 2. Bismuth is a sulphu∣rous Marcasite found in the Tin Mines, being nothing but the Excrement of a Metal Or an Earth impregnated with Metalick parts, Or an imperfect Tin, mixt with a good quantity of Arsenick: There are several kinds of it, but the principal one Bis∣muth and Zinck, of each of which, like preparations are made.
§ 3. Lemery makes them thus. Calcine Bismuth as you do Lead, then mixing it with equal parts of Sal-Armoniack proceed to its Sublimation, as you do in that of Tin following: So will you have Flowers which you may dissolve in Water, and precipitate with Spirit of Sal-Armoniack, or Oil of Tartar per deliquium.
§ 4. Le Febure makes them after this manner. ℞ Bis∣muth (as it comes from the Mine, and before it has ever felt the fire) in fine Pouder lb.j. New White-wine lb.ij. mix and digest in a double Vessel the space of three days: after which, decant the Wine and affuse lbij. more in the place: and this Work repeat the third and fourth time: The fourth part of the Wine digested af∣fuse on the Marcasite in a Cu∣curbit, which place in Sand, and cover it with an Alem∣bick, draw off the Menstruum with a moderate heat to dry∣ness: cohabate it with another fourth part, and distil off to dryness; and so proceed with the third fourth part, and the last fourth part; distilling to dryness. When all the Moi∣sture is come over, increase the fire, and there will su∣blime into the head silvered Flowers, which you may keep without any farther preparati∣on
