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 ...

Bate.] ℞ Quicklime lbj. Ashes of Wood lbss. Tartar, Nitre, A. ℥j. boil in Water, filter, and coagulate to dry∣ness.

Salmon.] § 1. This is ex∣actly from Schroder, but there are several other ways of making of this Salt, which seem to be better: Theophra∣stus takes Quicklime, and Bean Ashes, and makes a Lixivi∣um and coagulates.

§ 2. The Venetians take Quicklime lbj. Oak or Beech Ashes lbij. Sandiver, Vitriol calcin'd, Tartar, A. ℥ij. of which they make a Lixivium, and then a Salt.

§ 3. Marggrave makes it only of Pot-Ashes, by elixiva∣tion, filtration, evaporation, and reverberation, till the Salt

flows in the Crucible like Wa∣ter: then being cooled he dissolves it again in fair Water, and filters through Paper, then evaporates in a Glass body till the Cuticula e∣merges, and then sets it for a Night in a cold place, so a most white Salt will concreet, which is vulgarly called Sal Alcali, or Sal Alcalisatum, that is a Salt fixed or reverbe∣rated.

§ 4. All Alcalies power∣fully attenuate, open, re∣solve, melt Humors, and ef∣fervesce with Acids, not only to attemperate them, but al∣so totally to destroy them; from whence they conduce to the cure of almost infinite Diseases, viz. of all such, as proceed from and are gene∣rated of an Acid ferment, as flegmatick Diseases, Scurvy, Epilepsia, &c. Dose, ℈ss. ad ℈j.

§ 5. But all these things are properly spoken only of Marggrave's Sal Alcali, not of Schroders, which is the Text of our Author: the use of which Schroder saith, is only Chymical, and serves to se∣parate Gold from Copper, if it be cast on when it runs: as also, to make Silver run easie and melt.
