The foregoing extracts present the gist of the methods employed by the Nancy school of hypnotism. The hypnotic condition is induced solely by oral suggestion, and the disease is removed by the same means. There can be no doubt of the efficacy of the method, thousands of successful experiments having been made by the author and his colleagues. These experiments have demonstrated the existence of a power in man to control by purely mental processes,--the functions and conditions of the human body. They have thus laid the foundation of a system of mental therapeutics which must eventually prove of great value to mankind. But they have done more. They have demonstrated a principle which reaches out far beyond the realm of therapeutics, and covers all the vast field of psychological research. They have demonstrated the constant amenability of the subjective mind to control by the power of suggestion. It is not surprising that those who have discovered this great principle should insist upon its applicability to every phenomenon within the range of their investigations; but it is strange that they should fail to recognize a co-ordinate power governed by the same law, within the same field of operations. Yet this is true of the modern scientific school of hypnotism to-day. The Nancy school believes in the power of suggestion, but confines its faith to oral suggestion. Having demonstrated that _oral_ suggestion is efficacious in the production of psychic phenomena, they hold that _mental_ suggestion has no power in the same direction. Having demonstrated that certain phenomena can be induced independently of any so-called fluidic emanation or effluence from the hypnotist, they hold that no fluidic emanation is possible. These conclusions are not only illogical, they are demonstrably incorrect. The Christian scientists are constantly demonstrating the potency of purely telepathic suggestion by what they denominate "absent treatment;" _i.e._, treatment of sick persons without the knowledge of the patients. That there is a power emanating from the operator who hypnotizes by means of mesmeric passes, seems to be very well authenticated by the experiments recorded by the old mesmerists. It must be admitted, however, that many of their experiments do not conclusively prove anything, for the reason that they were made before suggestion as a constant factor in hypnotism had been demonstrated. Recent experiments by members of the London Society for Psychical Research have, however, now placed that question beyond a doubt. Their methods of investigation are purely scientific, and were made with a full knowledge and appreciation of the principle of suggestion, and of the distinction between mesmerism and hypnotism.
