    Take of your re£tified Aqua Fort is, as much as you pleafe; put it into a large Bolt-head, with a long Neck, but not above a Quarter full. Then take, of the pureft and fined Volatile Sal Armo- niac, in which there is not the lead Acid Salt, or Lime. [As I have ufually bought this Volatile Salt ready made, and doubt not but it may be had pure and genuine at Apothecary’s Hail, I have omitted here letting down the Procels for making it; having bought it of Mr. Godfrey, Chymid.] To fixteen Ounces of the aforefaid Aqua Fortis, in your Bolt-head, take feven Ounces of the faid Volatile Sal Armoniac ; and, by half an Ounce at a time, put it into your Bolt-head, to your Aqua Fortis, immediately Hopping the Mouth of your Bolt-head, till the Fermentation is over *, yet not fo clofe, but to leave fome fmall Vent, for fear the Wind, caufed by the violent Fermentation, fhould burd your Glafs.

Increafe your Fire a little, and put in a fmall Quantity more of Quickfilver; thus letting it didolve, by gentle Additions, as much as it will. When it will difiolve no more, take it out of the Bolt-head, put it into an open Glafs VedeJ, or a large White Stone Bowl. [I ge¬ nerally cut off a large Glafs Body in the.Middle.] Set
