“Staying at the well known country house in Kent of a distinguished London banker, formerly member of Parliament for Greenwich, I had been called upon to set to sleep, and to arrest a continuous barking cough from which a young lady who was staying in the house was suffering, and who, consequently, was a torment to herself and her friends. I thought this a good opportunity for a control experiment, and I sat her down in front of a lighted candle which I assured her that I had previously mesmerized. Presently her cough ceased and she fell into a profound sleep, which lasted until twelve o’clock the next day. When I returned from shooting, I was informed that she was still asleep and could not be awoke, and I had great difficulty in awaking her. That night there was a large dinner party, and, unluckily, I sat opposite to her. Presently she again became drowsy, and had to be led from the table, alleging, to my confusion, that I was again mesmerizing her. So susceptible did she become to my supposed mesmeric influence, which I vainly assured her, as was the case, that I was very far from exercising or attempting to exercise, that it was found expedient to take her up to London. I was out riding in the afternoon that she left, and as we passed the railway station, my host, who was riding with me, suggested that, as his friends were just leaving by that train, he would like to alight and take leave of them. I dismounted with him and went on to the platform, and avoided any leave-taking; but unfortunately in walking up and down it seems that I twice passed the window of the young lady’s carriage. She was again self-mesmerized, and fell into a sleep which lasted throughout the journey, and recurred at intervals for some days afterward.” In commenting on this, Dr. Hart notes that in reality mesmerism is self-produced, and the will of the operator, even when exercised directly against it, has no effect if the subject believes that the will is being operated in favor of it. Says he: “So long as the person operated on believed that my will was that she should sleep, sleep followed. The most energetic willing in my internal consciousness that there should be no sleep, failed to prevent it, where the usual physical methods of hypnotization, stillness, repose, a fixed gaze, or the verbal expression of an order to sleep, were employed.” The dangers of hypnotism have been recognized by the law of every civilized country except the United States, where alone public performances are permitted.
