Many other experiments were made quite satisfactorily, and similar results were produced in his city practice. In one case, by hypnotic suggestion treatment Dr. Voisin transformed the character of a quarrelsome woman, making her a mild affectionate wife to her husband. Voisin's experiments related principally to adults, but Dr. Liebeault of Nancy made experiments with children, of which he has mentioned two cases. Once a child was brought to his clinic with great suffering from a nervous affection, but would not submit to a hypnotic treatment till her little brother present offered himself, not being afraid. When he was put to sleep his mother told the physician that the boy in school was always in the lower grades, without making any progress. While in the sleep he was strongly impressed for diligence and zeal, and the subsequent result was perfect; within six weeks he became an example of diligence and perseverance, and soon got promoted. The second case was that of a young idiot. He was incapable of intellectual culture, and could not be taught reading or arithmetic. Dr. Liebeault submitted him to many hypnotic sittings, making a very great effort to rouse his attention, though he seemed to have no capacity for being instructed. Finally he succeeded so well that after two months he could read, and could cipher in the four rules of arithmetic. A great number of similar cases were treated by Dr. Dumont at Nancy with decided success. In one of his clinics Prof. Bernheim maintained that all children are receptive of hypnotic suggestion or transference of thought, and even more so when they enter the age of reasoning. Not only in sleep, but also in the waking condition, they may be affected; and the school of Nancy deserves great credit for presenting this important matter to the world in its true light. One of the signs of the hypnotic sleep or state is the automatic condition of the individual. In consequence of having for the time an enfeebled will, the individual will yield to all impressions upon it; and this weakness of will may take place in a wakeful state, when, if there is no opposition, the individual will accept all assurances in good faith. In case there is no exertion of influence by others, the subject will act by his or her own imagination. Such auto-suggestion is the result of a tendency to imitation which seems to be developed in children particularly, and develops in the waking state in undisciplined minds or in a fatigued and passive state. These important principles and facts render it the duty of every educator to study the efficacy of suggestion and imitation in children. The experiments made thus far, authorize us to establish the following rules for practice:
