Pharmacopœia Bateana, or, Bate's dispensatory translated from the second edition of the Latin copy, published by Mr. James Shipton : containing his choice and select recipe's, their names, compositions, preparations, vertues, uses, and doses, as they are applicable to the whole practice of physick and chyrurgery : the Arcana Goddardiana, and their recipe's intersperst in their proper places, which are almost all wanting in the Latin copy : compleated with above five hundred chymical processes, and their explications at large, various observations thereon, and a rationale upon each process : to which are added in this English edition, Goddard's drops, Russel's pouder [sic], and the Emplastrum febrifugum, those so much fam'd in the world : as also several other preparations from the Collectanea chymica, and other good authors / by William Salmon ...

CXVIII. Plumbum album, & Cerussa, White Lead, and Ceruse.

Bate.] Make Plates of Lead and hang them over Vinegar, so that the Vapors from the Vin••gar may environ or go round it: so will the Lead by little and little con∣vert into Ceruse.

Salmon.] § 1. Lead says Lemery is converted into Ce∣ruse or white Lead, by the help of Vinegar, whose Va∣pors it imbibes, by which means it is converted into a white Rust, which being ga∣thered is made into little Cakes: this is called white Lead; but if into one great Lump, it is called Ceruse; so that you may see there is no difference in the things, but in the Terms, and Form of making up.

§ 2. Charras reduces the Lead (after purification) into thin Plates, and then hangs them up over the Vapors of Vinegar put into a proper Vessel over a moderate Fire: so will a white Substance grow upon the Lead, which he separates and gathers to∣gether, and this is that says he, which they call Ceruse.

§ 3. It is of a drying Pro∣perty, and is used by Nurses to dry up galling and scald∣ings of Urine, in Infants, being reduced into Pouder, and strewed thereon with a Puff: It is also mixed with Unguents, and Plaisters where drying is required: it unites with Oils and fat

Substances in boiling, and gives them a solid Consisten∣cy, and there from, several Emplasters receive their Body and hardness.

§ 4. Saccharum Saturni, or Salt of Saturn is made out of several Preparations of Sa∣turn, as burnt Lead, Litharge Minium, or Red Lead; but it is most plentifully and easi∣ly made out of White Lead or Ceruse, because being more open, it is easier to dissolve than the other Preparations of Lead, by reason of the Vinegar, with which it is already impregnated, so that almost the whole Body of the Ceruse will convert into Salt; whereas in the other Prepa∣rations it is done with much more difficulty.

§ 5. Here is also to be no∣red, that this White Lead or Ceruse may be prepared by the Vapors of any other A∣cid, as A. F. Spirit of Ni••re, &c. as well as by those of Vine∣gar, forasmuch, as all Acids whatsoever corrode and rust it.
