Of an extremely sensitive patient, who was suffering with rheumatic pains, Mr. H. S. Thompson observes, “A few passes put her to sleep, though she was moaning as in great pain, and scarcely seemed to notice what I was doing. After sleeping for a few minutes, her face became composed, and she showed no symptoms of pain; but as I could not get her to speak in her sleep, I awakened her. She looked very much surprised, and said that she felt very comfortable and free from pain. I told my friend that she was so sensitive that I thought that she might be put to sleep by the will in a few minutes. The bed-curtains were drawn, so that she could not see or know what was going on. I fixed my attention upon her, wishing her to go to sleep. When we looked at her two minutes afterwards, she was fast asleep. It was agreed that the following day, though I should be thirty miles off, the experiment should be tried again. A lady went at the time fixed on. I purposely postponed the time half-an-hour, thinking that the woman might have become acquainted with my intention, and go to sleep through the power of the imagination. The lady’s account was, that she called upon the woman at the time agreed on, and at first thought that the experiment was going to fail, as she saw no symptoms of sleep; but that in half-an-hour afterwards the patient went into a deep sleep, which lasted some time. After this she went to sleep every day for a fortnight at the same time, though I did not will her to sleep. She says that she felt in a dreamy and happy state for some days after.” I might add many similar facts to the above interesting observations. The mass of evidence existing on the subject establishes beyond all doubt that patients have been thrown into trances by persons who have previously mesmerised them in the common way, at distances which seem to preclude the idea of any physical agent having been the medium of communication between the two parties. The operation seems to have been in those instances mental. Then how is such a result to be explained?—or by what expression can it be brought to tally with the principles I am endeavouring to substantiate? I shape the answer thus:— The first step is ordinary mesmerising; in other words, the operator directs an Od-current upon the patient, the Od in whose system is thereby disturbed; and initiatory trance ensues as the consequence.
