Erristus saith: Thou hast spoken most excellently, O Bonellus, and I bear witness to all thy words! The Turba saith: Tell us if there be any service in the speech of Bonellus, so that those initiated in this disposition may bemore bold andcertain. Erristus saith: Consider, all ye investigators of this Art, how Hermes, chief of the Philosophers, spoke and demonstrated when he wished to mix the natures. Take, he tells us, the stone of gold, combine with humour which is permanent water, set in its’ vessel, over a gentle fire until liquefaction takes place. Then leave it until the water dries, and the sand and water are combined, one with another; then let the fire be more intense than before, until it again becomes dry, and is made earth. When this is done, understand that here is the beginning of the arcanum; but do this many times, until two-thirds of the water perish, and colours manifest unto you. The Turpsa answereth: Thou hast spoken excellently, O Effistus! Yet, briefly inform us further. And he: I testify to posterity that the dealbation doth not take place save by decoction.* Consequently, Agadaimon has very properly. treated of cooking, of pounding, and of imbuing,t ethelia. Yet I direct you not to pour on the whole of the water at one time, lest the Ixir be submerged, but pour it in gradually, pound and dessicate, and do this several times until the water be exhausted. Now concerning this the envious have said: Leave the water when it has all been poured in, and it will sink to the bottom. But their intention is this, that while the humour is drying, and when it has been turned into powder, leave it in its glass vessel for forty days, until it passes through various colours, which the Philosophers have described. By this method of cooking the bodies put on their spirits and spiritual tinctures, and become warm.* The Turba answereth: Thou hast given light to us, O Effistus, and hast done excellently! Truly art thou cleared from envy; wherefore, let one of you others speak as he pleases.
