And they: Shew, therefore, how it is extracted. And he: It is pounded, and water is poured upon it seven times until it absorbs the whole humour, and receives a force which is equal to the hostility of the fire; then it is called rust. Putrefy the same diligently until it becomes a spiritual powder, of a colour like burnt blood, which the fire overcoming hath introduced into the receptive belly of Nature, and hath coloured with an indelible colour. This, therefore, have kings sought, but not found, save only to whom God has granted it.* But the Turba saith: Finish your speech, O Bacsen. And he: I direct them to whiten copper with white water, by which also they make red. Be careful not to introduce any foreign matter.
