To prepare the Crocus of Gold.

TAke the remainder of the Masse left after the evaporation of the dissolution of the Gold with salts above mentioned, and dissolve it in a slow heat, with as much distilled Rain-water as will be necessary to dissolve it; filtrate this dissolution through paper, and precipitate it with a sufficient quantity of oyle of ☿ per deliquium, poured upon it drop by drop, unless the Gold be pre∣cipitated to the bottom, then let it settle, and separate by decan∣tation the liquor swimming above it, and edulcorate the solar Cro∣cus with distilled Rain-water, then dry it gently and slowly. You must also precipitate again the liquor separated from above the Crocus with spirit of Urine, that in case there should remain yet any portion of Gold, it may be drawn off: after this, edulcorate what hath been precipitated and dry it, to join to the first Crocus, and reverberate in a Crucible with a moderate heat the space of about a quarter of an houre, and so shall you have a solar Cro∣cus very open, and of a fair purple Violet colour, which is an ex∣cellent Diaphoretick and a Cordial not to be despised. The Dosis must be from gr. φ. to v. or vj. in some Conserve or Cordial gelly. There may also a very excellent Diaphoretick and com∣fortative Powder be made out of it.
