“I postulate to begin with,” he said, “that we were all in precisely the right, expectant, slightly inert condition necessary to the production of phenomena. We were sitting in a circle, and our conscious minds were completely occupied with the subject of spiritualism. We were, in fact, according to the common agreement about such things, in the state that best enables us to assist any possible manifestations by--by giving out power. “The chief medium in the case was unquestionably the unconscious person of Miss Messenger. She was in what I may call an ideal trance for the purpose of manifestation. Also, by an extraordinary chance, her body was secluded and in darkness. If the conditions had been planned by experts they could hardly have been improved upon. After that our explanation of the apparition and of the ‘direct voice’ phenomena is largely dependent upon precedents. “With regard to the first, I claim that von Schrenck-Notsing’s photographs taken in Paris and elsewhere in 1912 and 1913 have sufficiently demonstrated that in favourable conditions and with a sensitive medium, a form of matter, not as yet scientifically described, may be drawn from the body of the medium and used by the external agency to build up representations not only of the human form, but also of familiar materials. I mention that in order that we may not be in any way disturbed by the fact that the materialisation was dressed in a gown of different colour from that worn by Miss Messenger. That gown too was instantly woven out of the creative flux. “Indeed, the only thing that was not so momentarily created and re-absorbed was the tulle scarf. That must actually have been taken from Miss Messenger’s unconscious body and handled by the temporary form evolved out of the teleplasm. There is good precedent for that, as I believe I said last night.” He paused a moment and then, as Harrison did not immediately reply, he added: “And if we are all agreed, after we have finished our discussion this evening, I would like to have separate written accounts from each of you as to your sight of the phenomenon; those, backed by the evidence of Mr. Messenger, his daughter and the police sergeant, ought, I think, to establish one of the most remarkable and convincing cases ever reported to the S.P.R.” “Steady, steady, Vernon,” Harrison put in. “I can’t say that I’m absolutely convinced as yet.” “What’s the alternative explanation?” Vernon asked. “That it was Miss Messenger herself whom we saw in a state of trance,” Harrison said. “You see I concede you the trance.” “But, my dear man,” Vernon expostulated, “the figure we saw by the wood was not like Miss Messenger.” “No?” Harrison replied. “Very well, let’s analyse the differences as observed by the various witnesses. You begin, Vernon. Was there any difference in height?” “None to speak of that I noticed,” Vernon admitted, “but that woman had a distinctly more spiritual face than Miss Messenger.”
