Allumina Changed to Silver—Late Process.—Put it into a crucible, first breaking it into small fragments, bring it to a white heat for five or six hours, until the metal will stand firm on a red-hot plate of iron; then sprinkle it with a mixture of vinegar and sal ammoniac (parts equal), when it is cold, put it again into the furnace, and keep at a white heat for three days and three nights, the last three or four hours adding a little pure lead to make it ductile; you now break it once more into small fragments and replace it in the furnace, adding to it little pills made of lime, saltpetre, and brimstone, and by this means our mixture becomes incorporated into a pretty good silver. To Cause Letters, Papers, &c., to Disappear.—Valivoni, an old magician, of the time of Agrippa, says: “If you take uphorbium, bdellium, gum armoniac, the roots of both hellebores, the loadstone, and a little sulphur, and incorporate them altogether with the blood of a hart, the blood of an elephant, and the blood of a black cat, and sprinkle it near the papers to be removed, that it unseals them and brings them to your presence, or just where you desire.” To Strike Fear and Terror into the Heart of an Enemy.—Pythagoras says: “That if a flame be put into the skull of a murderer, and the flame of your enemy written therein, it will strike the person whose name is so written with fear and trembling, and he will speedily seek your forgiveness and become a steadfast friend.” 55 By what means Magicians and Necromancers call forth the souls of the dead. It is manifest that the souls after death do as yet love their bodies which they left, as those souls do whose bodies want due burial, or have left their bodies by violent death, and yet wander about their carcasses in a troubled and moist spirit, beings as it were, allured by something that has an affinity with them, the means being known, by which, in time past, they were joined to their bodies, they be called forth and allured by the like vapors, liquors and certain artificial lights, songs, sounds, &c., which move the imaginative and spiritual harmony of the soul, and sacred invocations, &c. Necromancy has its name because it works on the bodies of the dead, and gives answers by apparitions of the dead, and subterraneous spirits, alluring them into the carcasses of the dead by charms and infernal invocations, and by deadly sacrifices and wicked oblations. There are two kinds of necromancy: raising the carcasses, which is not done without blood; the other in which the calling up of the shadow only suffices. To conclude, it works all its experiments by the carcasses of the slain, and their bones and members, and what is from them.
