Choosing a time when there is a favourable conjunction of the planets, the magician, armed with the implements of magical art, after much prayer and fasting, betakes himself to a suitable spot, alone, or perhaps accompanied by two trusty companions. All the articles he intends to employ, the vestments, the magic sword and lamp, the talismans, the book of spirits, _etc_., have been specially prepared and consecrated. If he is about to invoke a martial spirit, the magician's vestment will be of a red colour, the talismans in virtue of which he may have power over the spirit will be of iron, the day chosen a Tuesday, and the incense and perfumes employed of a nature analogous to Mars. In a similar manner all the articles employed and the rites performed must in some way be symbolical of the spirit with which converse is desired. Having arrived at the spot, the magician first of all traces the magic circle within which, we are told, no evil spirit can enter; he then commences the magic rite, involving various prayers and conjurations, a medley of meaningless words, and, in the case of the black art, a sacrifice. The spirit summoned then appears (at least, so we are told), and, after granting the magician's request, is licensed to depart--a matter, we are admonished, of great importance. The question naturally arises, What were the results obtained by these magical arts? How far, if at all, was the magician rewarded by the attainment of his desires? We have asked a similar question regarding the belief in talismans, and the reply which we there gained undoubtedly applies in the present case as well. Modern psychical research, as I have already pointed out, is supplying us with further evidence for the survival of human personality after bodily death than the innate conviction humanity in general seems to have in this belief, and the many reasons which idealistic philosophy advances in favour of it. The question of the reality of the phenomenon of "materialisation," that is, the bodily appearance of a discarnate spirit, such as is vouched for by spiritists, and which is what, it appears, was aimed at in necromancy (though why the discarnate should be better informed as to the future than the incarnate, I cannot suppose), must be regarded as _sub judice_.(1) Many cases of fraud in connection with the alleged production of this phenomenon have been detected in recent times; but, inasmuch as the last word has not yet been said on the subject, we must allow the possibility that necromancy in the past may have been sometimes successful. But as to the existence of the angels and devils of magical belief--as well, one might add, of those of orthodox faith,--nothing can be adduced in evidence of this either from the results of psychical research or on _a priori_ grounds. (1) The late Sir WILLIAM CROOKES' _Experimental Researches in the Phenomena of Spiritualism_ contains evidence in favour of the reality of this phenomenon very difficult to gainsay.
