CASES OF HYPNOTIC SUGGESTION.--Among minor instances of this result, Frederick Myers relates that he suggested to a hypnotised subject, who was engaged in coloring a sketch, that it would be a good idea to paint the bricks blue. He repeated his suggestion several times, and then brought the subject to the normal state. She had no recollection of what had passed, yet on resuming her painting some time afterwards she hesitated, and then said to a lady companion, "I suppose it would never do to paint these bricks blue." "Why blue?" "Oh, it only occurred to me that it would look rather nice." She acknowledged that the idea of blue bricks had been persistently in her mind, with the notion that the color would look well. In another instance, Dr. Bernheim, of Nancy, suggested to a hypnotised person to take Dr. X.'s umbrella when awake, open it, and walk twice up and down the gallery. On being awakened he did so, but with the umbrella _shut_. When asked why he acted so, he replied: "It is an idea. I take a walk sometimes." "But why have you taken Dr. X.'s umbrella?" "Oh, I thought it was my own. I will replace it." These are harmless instances of this strange power. There are others the reverse of harmless in this significance. One or two of these we may quote: Prof. Liegeois, in his recently published pamphlet, "Of Hypnotism in its relations to Civil and Criminal Law," describes experiments with the subjects of M. Liebault, a well-known hypnotiser. In these experiments he took pains to induce the patients to commit crimes. As he relates, Mdlle. A. E. (a very amiable young lady) was made to fire at her own mother with a pistol, which she had no means of knowing was unloaded. The same lady was made to accuse herself before a judge of having assassinated an intimate friend with a knife. Yet in both these instances she was wide awake at the time and supposed that she was acting from her own impulse. Many other instances might be given, but these will suffice for illustration. As to the length of time in which such a suggestion may remain operative, Prof. Beaunis relates a case in which he suggested to a hypnotised subject that he would call on her on the next New Year's day (172 days after the date of the experiment). On that date, being perfectly conscious, she seemed to see him walk into the room where she was, pay his compliments, and retire. She insisted that this had really happened, and could not be convinced to the contrary. A striking feature of this incident was that he seemed to be dressed in summer attire (as at the date of experiment), though it was now the dead of winter.
