Time and scientific progress have largely overthrown Mesmer’s theories of the fluid; yet Mesmer had made a discovery that was in the course of a hundred years to develop into an important scientific study. Says Vincent: “It seems ever the habit of the shallow scientist to plume himself on the more accurate theories which have been provided for him by the progress of knowledge and of science, and then, having been fed with a limited historical pabulum, to turn and talk lightly, and with an air of the most superior condescension, of the weakness and follies of those but for whose patient labors our modern theories would probably be non-existent.” If it had not been for Mesmer and his “Animal Magnetism”, we would never have had “hypnotism” and all our learned societies for the study of it. Mesmer, though his pretensions were discredited, was quickly followed by Puysegur, who drew all the world to Buzancy, near Soissons, France. “Doctor Cloquet related that he saw there, patients no longer the victims of hysterical fits, but enjoying a calm, peaceful, restorative slumber. It may be said that from this moment really efficacious and useful magnetism became known.” Every one rushed once more to be magnetized, and Puysegur had so many patients that to care for them all he was obliged to magnetize a tree (as he said), which was touched by hundreds who came to be cured, and was long known as “Puysegur’s tree”. As a result of Puysegur’s success, a number of societies were formed in France for the study of the new phenomena. In the meantime, the subject had attracted considerable interest in Germany, and in 1812 Wolfart was sent to Mesmer at Frauenfeld by the Prussian government to investigate Mesmerism. He became an enthusiast, and introduced its practice into the hospital at Berlin. In 1814 Deleuze published a book on the subject, and Abbe Faria, who had come from India, demonstrated that there was no fluid, but that the phenomena were subjective, or within the mind of the patient. He first introduced what is now called the “method of suggestion” in producing magnetism or hypnotism. In 1815 Mesmer died. Experimentation continued, and in the 20’s Foissac persuaded the Academy of Medicine to appoint a commission to investigate the subject. After five years they presented a report. This report gave a good statement of the practical operation of magnetism, mentioning the phenomena of somnambulism, anesthesia, loss of memory, and the various other symptoms of the hypnotic state as we know it. It was thought that magnetism had a right to be considered as a therapeutic agent, and that it might be used by physicians, though others should not be allowed to practice it. In 1837 another commission made a decidedly unfavorable report.
