The Fourth Operation.

PUT your Matter so dissolved into a Ma∣trass, close it, and dissolve it in A. B. into Water with a continual slow heat: Di∣still this Water in a little Alembick on Ashes with a slow fire of a Lamp, and Water of Paradise will be distilled, (of which alone the stone may be made by the Method after described) one drop of which poured upon a Plate of any red-hot Metal will throughly whiten it within and without; (Note, that the like may be done with the Lunary made of ☽ and ♃ if they be pour••d on a Plate of ♀.) After the water is distilled, some faeces will remain, which contain in them Earth, Air, and Fire, which you may thus separate

one from another: Beat those faeces, and di∣gest them in an Athanor, as you did the Quintessence before, afterwards dissolve them the same way in M. B. At last distill with a very strong fire in M. B. by an Alembick, a white Oyl, which is called Air, which when it ceaseth to drop any more, take off the Recipient, and close well the nose of the Alembick, and so let it cool of it self: Then set the Alembick with a new Recipient on Ashes, and draw off the red Oyl (which is called fire) with a strong fire. Cast away the Earth that remains.
