"The subject of my experiments," said he, "was a young woman of good family, who was credited with having exceptional ability in divining the thoughts and wishes of others. It was arranged that I should investigate her powers, and accordingly for a period of some weeks I had frequent sittings with her, in the presence of a few interested and trustworthy friends. "The plan followed in every experiment was this: The young woman having left the room, I mentally selected some more or less complicated action for her to perform upon her return. I then wrote down on a slip of paper what I wished her to do, showed it to the others, and concealed it in a book, which did not leave my hand until after the completion of the experiment. From first to last not a word was spoken by any one, so as to guard against any possible hyperæsthesia of hearing on her part. "The young woman was then called back, and almost invariably proceeded to execute the commands mentally given her. She did this so promptly that I cannot conceive how she could possibly have got any unconscious hints from those present, and conscious signaling was out of the question. "For instance, I once wrote on my paper an order for her to pick out of a vase a bunch of keys I had hidden there, cross the room with the keys, and place them on the mantel-piece. She entered, stood for but a moment with her eyes closed, and then, swiftly passing to the vase, which was on the floor, picked up the keys, turned, and deposited them on the mantel-piece as I had mentally suggested. It was all done so quickly and spontaneously that to my mind it afforded strong evidential proof of true thought transference. "She was not always successful, but some of her failures were quite as instructive as her successes. On three occasions she executed, not the commands I had written on the paper, but commands I had thought of writing but for one reason or another had abandoned. No one in the room excepting myself knew of these previous intentions, so she could have derived her knowledge of them from the involuntary movements of no one excepting me; and if it had actually been a matter of subconscious guidance, it is obvious that my muscular indications would have related not to the abandoned commands but to the commands I actually wished her to carry out. "All things considered, my experiments with this young woman satisfy me that the hypothesis of subconscious guidance is not always properly applicable, even when the 'mind reader' is in a position to see or hear the persons testing him."
