It is to this society, and not to the S.P.R. as at present conducted, that the world may look for accurate information upon this subject. It would not be reasonable for me to go at any length here into the results obtained. I would only say that so far as my own conclusions go, basing my studies upon the photographers of the past as well as the present, I think that the evidence is strong that there is on the other side an intelligent control for each photographic medium, whose powers are great but by no means unlimited and who endeavours to give us convincing results each in his own characteristic way. These results are sometimes obtained by actual materialisations, sometimes by precipitations of pictures apart from exposure, sometimes, as I believe, by the superposition of screens which have the psychic face already upon them, and which give marks as of a double exposure. Among the powers of the control is to build up a simulacrum which may be the image of someone who is still alive, or he may produce upon the plate facsimiles of pictures and portraits which do at present exist, but which are entirely beyond the normal reach of the medium. All these and other equally strange points I could illustrate by many examples, but their mere recital will show how many snares lie before the explorer, and how many things might seem to be fraudulent when they are really the doing not of the medium but of the control. Any further expansion of this fascinating subject would be out of place on my part, since I am by no means one of the authorities, and can only claim that I study and assimilate the results of others, to which, of course, I add my own personal experience. I have, however, asked Mr. Barlow, the Honorary Secretary of this Society, whose experience is so extensive as to be almost unrivalled, to add a short essay upon the subject, with an account of some of the cases which bear upon the matter. CHAPTER VI THE ATTACK ON MRS. DEANE AND MR. VEARNCOMBE I took up my pen for the purpose of considering the case of the Crewe Circle and urging the folly of discarding the work of seventeen years on the score of a single case. I cannot, however, end my task without saying a few words as to the attack upon Mrs. Deane and Mr. Vearncombe, two other photographic mediums. This attack hardly deserves attention as it was anonymous, but it was brought out under the auspices of the Magic Circle, a society of conjurers who have been interesting themselves in matters psychic. As the two attacks were issued almost simultaneously they seem to have had some common inspiration, and to have formed a general assault upon the whole position of psychic photography. The same individual, Mr. Seymour, the amateur conjurer, actually took part, I understand, in both transactions.
