Notwithstanding the pompous announcements, magnetism already could no longer be considered as a certain indicator of diseases. Here the reporter made a capital remark: magnetism appeared to have no effect on incredulous persons who had submitted to the trials, nor on children. Was it not allowable to think, that the effects obtained in the others proceeded from a previous persuasion as to the efficacy of the means, and that they might be attributed to the influence of imagination? Thence arose another system of experiments. It was desirable to confirm or to destroy this suspicion; "it became therefore requisite to ascertain to what degree imagination influences our sensations, and to establish whether it could have been in part or entirely the cause of the effects attributed to magnetism." There could be nothing neater or more demonstrative than this portion of the work of the commissioners. They go first to Dr. Jumelin, who, let it be observed, obtains the same effects, the same crises as Deslon and Mesmer, by magnetizing according to an entirely different method, and not restricting himself to any distinction of poles; they select persons who seem to feel the magnetic action most forcibly, and put their imagination at fault by now and then bandaging their eyes. What happens then? When the patients see, the seat of the sensations is exactly the part that is magnetized; when their eyes are bandaged, they locate these same sensations by chance, sometimes in parts very far away from those to which the magnetizer is directing his attention. The patient, whose eyes are covered, often feels marked effects at a time when they are not magnetizing him, and remains, on the contrary, quite passive while they are magnetizing him, without his being aware of it. Persons of all classes offer similar anomalies. An instructed physician, subjected to these experiments, "feels effects whilst nothing is being done, and often does not feel effects while he is being acted upon. On one occasion, thinking that they had been magnetizing him for ten minutes, this same doctor fancied that he felt a heat in his lumbi, which he compared to that of a stove." Sensations thus felt, when no magnetizing was exerted, must evidently have been the effect of imagination. The commissioners were too strict logicians to confine themselves with these experiments. They had established that imagination, in some individuals, can occasion pain, and heat--even a considerable degree of heat--in all parts of the body; but practical female Mesmerizers did more; they agitated certain people to that pitch, that they fell into convulsions. Could the effect of imagination go so far? Some new experiments entirely did away with these doubts.
