One day, while attempting to hypnotize her in another street, three hundred yards distant, at 3 o'clock P. M., he was suddenly called away to attend a patient, and forgot all about his hypnotic subject. Afterward he remembered that he was to meet her at 4:30, and went to keep his appointment. But not finding her, he thought possibly the experiment, which had been interrupted might, after all, have proved successful. Upon this supposition, at 5 o'clock he willed her to awake. That evening, without being questioned at all, she gave the following account of herself: At 3 P. M. she was overcome by an irresistible desire to sleep, a most unusual thing for her at that hour. She went into an adjoining room, fell insensible upon a sofa, where she was afterward found by her servant, cold and motionless, as if dead. Attempts on the part of the servant to rouse her proved ineffectual, but gave her great distress. She woke spontaneously and free from pain at 5 o'clock. By no means the least interesting of the higher phenomena of hypnotism are post-hypnotic suggestions, or the fulfilment after waking of suggestions impressed upon the subject when asleep. A few summers ago at a little gathering of intelligent people, much interest was manifested and a general desire to see some hypnotic experiments. Accordingly, one of the ladies whose good sense and good faith could not be doubted, was hypnotized and put into the condition of profound lethargy. After a few slight experiments, exhibiting anæsthesia, hallucinations of taste, plastic pose, and the like, I said to her in a decided manner: "Now I am about to waken you. I will count five, and when I say the word 'five' you will promptly, but quietly and without any excitement, awake. Your mind will be perfectly clear, and you will feel rested and refreshed by your sleep. Presently you will approach Mrs. O., and will be attracted by the beautiful shell comb which she wears in her hair, and you will ask her to permit you to examine it." I then commenced counting slowly, and at the word "five" she awoke, opened her eyes promptly, looked bright and happy, and expressed herself as feeling comfortable and greatly rested, as though she had slept through a whole night. She rose from her chair, mingled with the company, and presently approaching Mrs. O., exclaimed: "What a beautiful comb! Please allow me to examine it." And suiting the action to the word, she placed her hand lightly on the lady's head, examined the comb, and expressed great admiration for it; in short, she fulfilled with great exactness the whole suggestion. She was perfectly unconscious that any suggestion had been made to her; she was greatly surprised to see that she was the centre of observation, and especially at the ripple of laughter which greeted her admiration of the comb.
