Dr. Cocke describes one or two experiments of his own which have an important bearing on the question of criminal suggestion. Says he: “A girl who was hypnotized deeply was given a glass of water and was told that it was a lighted lamp. A broomstick was placed across the room and she was told that it was a man who intended to injure her. I suggested to her that she throw the glass of water (she supposing it was a lighted lamp) at the broomstick, her enemy, and she immediately threw it with much violence. Then a man was placed across the room, and she was given instead of a glass of water a lighted lamp. I told her that the lamp was a glass of water, and that the man across the room was her brother. It was suggested to her that his clothing was on fire and she was commanded to extinguish the fire by throwing the lighted lamp at the individual, she having been told, as was previously mentioned, that it was a glass of water. Without her knowledge a person was placed behind her for the purpose of quickly checking her movements, if desired. I then commanded her to throw the lamp at the man. She raised the lamp, hesitated, wavered, and then became very hysterical, laughing and crying alternately. This condition was so profound that she came very near dropping the lamp. Immediately after she was quieted I made a number of tests to prove that she was deeply hypnotized. Standing in front of her I gave her a piece of card-board, telling her that it was a dagger, and commanded her to stab me. She immediately struck at me with the piece of card-board. I then gave her an open pocketknife and commanded her to strike at me with it. Again she raised it to execute my command, again hesitated, and had another hysterical attack. I have tried similar experiments with thirty or forty people with similar results. Some of them would have injured themselves severely, I am convinced, at command, but to what extent I of course cannot say. That they could have been induced to harm others, or to set fire to houses, etc., I do not believe. I say this after very careful reading and a large amount of experimentation.” Dr. Cocke also declares his belief that no person can be hypnotized against his will by a person who is repugnant to him. The facts in the case are probably those that might be indicated by a common-sense consideration of the conditions. If a person is weak-minded and susceptible to temptation, to theft, for instance, no doubt a familiar acquaintance of a similar character might hypnotize that person and cause him to commit the crime to which his moral nature is by no means averse. If, on the other hand, the personality of the hypnotizer and the crime itself are repugnant to the hypnotic subject, he will absolutely refuse to do as he is bidden, even while in the deepest hypnotic sleep. On this point nearly all authorities agree.
