hallucination, but highly picturesque, and in some quarters accepted quite seriously. In like manner, concerning the existence of Satanic associations, and especially the Palladium, M. Huysman admittedly derives his knowledge from published sources. We may take it, therefore, that he speaks from an accidental and extrinsic acquaintance, and he is therefore insufficient in himself to create a question of Satanism; he indicates rather than establishes that there is a question, and to learn its scope and nature we must have recourse to the witnesses who claim to have seen for themselves. These are of two kinds, namely, the spy and the seceder--the witness who claims to have investigated the subject at first hand with a view to its exposure, and those who have come forward to say that they once were worshippers of Lucifer, worshippers of Satan, operators of Black Magic, or were at least connected with associations which exist for these purposes, who have now, however, suspended communication, and are stating what they know. In the first class we find only Doctor Bataille; in the second, Diana Vaughan, Jean Kostka, Domenico Margiotta, and Leo Taxil. Finally, we have, as stated in the preface, some testimony from writers representing the interests of the Latin Church, in a special manner, and speaking with the authority of that Church. The most important of these is the late Archbishop Meurin. At the same time, M. Huysman apart--who occupies much the same quasi-religious position as that which attached a fleeting interest to the personality of Mr W. H. Mallock--all writers and all witnesses are, or assume to be, at the present time, convinced and zealous Roman Catholics. I have already stated that the purpose of Black Magic is simply and obviously to communicate with devils, and if we interrogate our sources of knowledge as to the object of such communication, it must be admitted that the response is vague. Perhaps the object will best be defined as the reinforcement of human ability by diabolical power and intelligence for the operation of evil along the lines of individual desire and ambition. For the fulfilment of what is good man aspires towards God, and to fulfil evil he attempts to conspire with Satan.
