Our forefathers had a strong faith in the power of magic, and even divided the knowledge of it into two opposite kinds--viz., "white magic," which was acquired from the communications of the archangels and angels, or at least from some of the good spirits who were allowed to aid human beings by their supernatural power in deeds of beneficence; and black magic, or "the black art," also termed "necromancy," which was derived from dealings with the devil, or at least from commerce with his imps, or the evil spirits of wicked dead men. At one period the terms magician and conjuror had the same meaning--one who conjured, by magical power, spirits and demons to appear and do his bidding. Conjuror has since become a name for a professor of _legerdemain_ or sleight-of-hand. EDWARD KELLY, THE SEER. Edward Kelly, whose dealings in the Black Art, it is said, would fill a volume, was born at Worcester, and had been an apothecary. We have elsewhere noticed his doings as an alchemist. He was for a considerable time the companion and associate of "Dr." John Dee, performing for him the office of "Seer," by looking into the doctor's crystal or stone, a faculty not possessed by Dee, who in consequence was obliged to have recourse to Kelly for the revelations he has published respecting the world of spirits. These curious transactions may be found in Casaubon's work, entitled, _A True and Faithful Relation of what Passed for many years between Dr. John Dee and some Spirits_--opening out another dark page in the history of imposture and credulity. Dee says that he was brought into unison with Kelly by the mediation of the angel Uriel. Afterwards he found himself deceived by him, in his opinion that these spirits which ministered unto him were messengers of the Deity. They had had several quarrels before; but when Dee found Kelly degenerating into the worst species of the magic art, for the purposes of avarice and fraud, he broke off all connexion with him, and would never afterwards be seen in his company. Kelly, being discountenanced by the doctor, betook himself to the meanest practices of magic, in all which money and the works of the devil appear to have been his chief aim. Many wicked and abominable transactions are recorded of him.
