This classifying of my experiments is only to bring on their mention in the order in which they seem to increase in importance. As a fact, the same faculties attend to them all. Still, the division is useful. Second, then, come those which dealt with long distances. To one of my first patients (a messenger in a law-office) I showed scenes in Syria, Egypt, Athens, and Rome, and after I had removed him from the mesmeric sleep I handed him a pile of photographs which I had brought from foreign countries. He turned them over rapidly and picked out the picture of the scene he had witnessed, and without hesitation. I ranked all this class next to lowest in importance because I had the scenes in my own mind at the time. Yet the patients saw more than I was thinking of. When I showed this messenger the obelisk in front of St. Peter's at Rome, he also described the great colonnade around the piazza, which I had at the moment forgotten. Subsequent experiments with others made me know that he was viewing the scene itself. The class ranked third, or next higher, were those in which the patients were called from a distance. In the Arlington Heights Sanitarium some of the patients formerly received, and I suppose still receive, beneficial hypnotic treatment. One patient, Grace ----, could be called into the office at any time by the simple will of Dr. Ring, the proprietor. I received the account from a valued nurse who attended this patient in the hospital. I was able to do the same thing myself in one case, but only when the patient was at some occupation which did not require much concentration. I am not prepared to speak as to the spaces across which this influence may be exerted. With another patient, who was over two miles away, the experiment seemed fairly successful, but I am not sufficiently certain to claim a success. In class four, the patients told facts which had not been previously within their knowledge or mine. For tests of this kind I would procure from friends some old coins wrapped up so that I could not know the dates on them. When the first patient with whom this was tried was told to pass into the sleep she called out the date of the coin almost instantaneously--"1793." I thought she was still awake and guessing. But in that instant she had passed into a deep sleep and had told the date correctly.
