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 ...

XXXI. Tinctura Oculorum Cancrorum, Tincture of Crabs Eyes.

Bate.] ℞ Crabs Eyes in fine Pouder ℥iv. the best Wine Vi∣negar ℥xvj. mix, extract the Tincture and filter. Dose two spoonfuls thrice a day, for the Curing of Ulcers. K. D. E. A.

Salmon.] § 1. This is from Sir Kenelm Digby, and is ra∣ther a dissolution of Crabs Eyes than a Tincture; if you would extract the true Tincture, it must be done in all respects as that of Coral, or Pearl.

§ 2. The chief use of this Medicine is in the curing of old Ulcers and Fistula's, which have been of long standing, and supposed to be past cure, in which it is said to do wonders; but in my Opinion, it would be much better to precipitate the dis∣solved Matter, and free it from the acidity of the Vine∣gar, by many Lotions, and then it may be given à ʒj. ad ʒij. But as to this, let Ex∣perience guide you, for that

the dissolution of the Oculi do better in some, the precipitate in others.

§ 3. Whether you give the dissolution, or the precipitate, this is always to be under∣stood, that they ought to be given in a proper Traumatick or Vulnerary Liquor, which may also contribute to the same intention.

§ 4. The way by which this Medicine works is, by a Diuretick property, carrying off the Morbifick Matter, which feeds the Disease, by Urine, which it does very sensibly, in such who conti∣nue the use of it for some time.

§ 5. Hofman is of the O∣pinion, That if this Liquor be made, it ought to be done with the Spirit of Venus, or Juice of Citrons; the one is a better Dissolver than Vin••∣gar, and the other makes a better dissolution, and with∣out doubt is to be preferred before that made with Vine∣gar: but the Artist may use what likes him best.
