The Simple are these.

Aes ustum, Lead made to Pow∣der, the Amalgama of Lead and Quick-silver beat to Powder. When you would make this, melt two ounces of Lead in a Crucible, then take it from the Fire, and put to it an ounce and a half of Mercu∣ry; these will incorporate toge∣ther; when the Mass is cold, you may beat it to a Powder. The Pumice-stone and Cuttle-bones cal∣cined, Stags-horn calcined white, all bones well calcined, the Head of Vitriol after the Spirit is drawn, well washed and dried; it is called by the Chymists Henricus Rubeus, and indeed it is a potent desiccative. Chalk powdered is good; to drive it into Powder, you must rub it upon a broad Tile somewhat fine, and then scarce it; otherwise you shall hardly do it. Terra sigillata, Bole-Armenick, Umber, are good; and unslaked Lime, well washed and dried, Alabaster beat to powder, Minium, Litharge, Cerusse, Cala∣minaris, Tutia, Regulus of Anti∣mony, Crocus Martis, Galls, Pome∣granate-flowers and Rinds, Com∣frey Roots, Sandarach of the Greci∣ans, Egg-shells calcined, the Roots of Tormentil and Bistort, Swine's-grease, Dear's and Sheep's-suet.
