“The house of one of these, namely Mr. Wallace, I have already visited, and made there the acquaintance of the lady who was the reputed medium between Mr. Wallace and the supernatural. “And if earnestly invited by Mr. Crookes, the editor of the ‘Chemical News,’ to witness phenomena which in his opinion ‘tend to demonstrate the existence of some power (magnetic or otherwise) which has not yet been recognized by men of science,’ I should pay due respect to his invitation. “But understand my position: more than a year ago Mr. Cromwell Varley, who is, I believe, one of the greatest modern Spiritualists, did me the favor to pay me a visit, and he then employed a comparison which, though flattering to my spiritual strength, seems to mark me out as unfit for spiritual investigation. He said that my presence at a _seance_ resembled that of a great magnet among a number of small ones. I throw all into confusion. Still he expressed a hope that arrangements might be made to show me the phenomena, and I expressed my willingness to witness such things as Mr. Varley might think worth showing to me.

This is the question which many people are asking, but to which no one seems prepared to give a satisfactory reply. Has this Report, which was to settle the question of Spiritualism, only unsettled the Dialectical Society--causing, as we learn, some of its principal officers and members to secede from it on finding that the investigations of the Committee pointed in a different way to what they anticipated, and to which they had committed themselves? People ask--Have the Committee come to an opinion on the subject or have they too many opinions?” The only information I have come in contact with referring to the Dialectical Committee and its work has been from Spiritualistic publications, most of them under authorship of Mr. James Burns, and I copy the following from “The Medium and Daybreak” of November 16, 1877:
