Mr. Sellers: You may, however, be able to explain to me a very remarkable slate-writing experiment which Kellar has performed. I will state the details of it. [Mr. Sellers here described at length Mr. Kellar's trick with the fastened slates, and in concluding, asked:] How did Mr. Kellar do that? Dr. Slade: He is a Medium. He does that work precisely as I do it. Mr. Sellers: But can he not do it by trickery? Dr. Slade: No it is impossible. He is a Medium, and a powerful Medium. (Mr. Sellers continued the reading of his transcript, as follows): Then I described to the Medium an experiment by Kellar in lifting a table ostensibly merely by laying his hands upon it, and I detailed his explanation of how deceptions might occur, his custom of pulling up his sleeves and exhibiting his hands to the audience. I added, that he had done the same thing with a chair. Dr. Slade: I do that thing, too. I will show you how I do it the next time. He does it as I do it. He is a Medium. (Mr. Sellers here paused to make the following verbal explanation): I pause here for the express purpose of having the fact noted that, being thoroughly familiar with the details of the methods of these experiments, I can positively assure the Committee that there is no Mediumistic power in Mr. Kellar, so far as his methods are concerned, that those methods are as easy of solution as are any other physical problems. (Resuming, from notes): The inquiry was then addressed to Dr. Slade, 'Do you know a man named Guernella who, with his wife, gave séances?' 'Yes,' he replied, 'I know him very well.' 'Well, how does he perform his wonderful exploits in rappings, etc.?' 'He is a Medium, a powerful Medium. I know him very well indeed. I can assure you that all that he does is done solely by means of his Mediumistic powers.' I now state to the Committee that the Guernellas exhibited in Philadelphia some years ago as exposers of Spiritualism. They did not expose it, but they performed experiments which, prior to that time, were said to have been accomplished by the aid of Spirits. Guernella himself, at my house, in my presence, in broad daylight, performed all the feats and exhibited the phenomena that were produced at the dark and other séances, and he repeated them until I myself became as expert as he in performing them; for which I paid him a consideration. So much for the Mediumistic power. (Resuming, from notes): Before the close of this last séance, a letter was read to Dr. Slade by Mr. Furness, to which the Medium was requested to make reply at his convenience; the object was to preserve evidence of the fact that the Medium had stated that all the séances must be held under his conditions--that if the Committee deviated in the slightest degree from the conditions imposed by him (Dr. Slade) he would 'pack up his traps and clear out.' [The letter and reply will be found annexed to this Record.]
