While in the deep sleep, and perfectly insensible to ordinary stimuli, however violent, contact, or even the proximity of her hypnotizer's hand, caused contractures, which a light touch from him would also remove. No one else could produce the slightest effect. After about ten minutes in this deep trance she usually passed into the alert, or somnambulic stage, from which also no one but the operator could arouse her. Hypnotization was difficult or impossible unless the operator concentrated his thoughts upon the desired result, but by simply willing, without passes or any physical means whatsoever, the hypnotic condition could be quickly induced. Various experiments in simply willing post-hypnotic acts, without suggestion through any of the ordinary channels of communication, were also perfectly successful. Dr. Gibert then made three experiments in putting this subject to sleep when she was in another part of the town, a third of a mile away from the operator, and at a time fixed by a third person, the experiment also being wholly unexpected by the subject. On two of these occasions Prof. Janet found the subject in a deep trance ten minutes after the willing to sleep, and no one but Dr. Gibert, who had put her to sleep, could rouse her. In the third experiment the subject experienced the hypnotic influence and desire to sleep, but resisted it and kept herself awake by washing her hands in cold water. During a second series of experiments made with the same subject, several members of the Society for Psychical Research were present and took an active part in them. Apart from trials made in the same or an adjoining room, twenty-one experiments were made when the subject was at distances varying from one-half to three-fourths of a mile away from her hypnotizer. Of these, six were reckoned as failures, or only partial successes; there remained, then, fifteen perfect successes in which the subject, Mme. B., was found entranced fifteen minutes after the willing or mental suggestion. During one of these experiments, the subject was willed by Dr. Gibert to come through several intervening streets to him at his own house, which she accomplished in the somnambulic condition, and under the observation of Prof. Janet and several other physicians. Another series of experiments was made with another subject by Dr. Héricourt, one of Prof. Richet's coadjutors. The experiments included the gradual extension of the distance through which the willing power was successful, first to another room, then to another street, and a distant part of the city.
