Presently a young man came in, of a good countenance and certainly of a very respectable exterior. As the _somnambule_ had left us, and this person could not consult her, which was his avowed intention in coming, M. C---- proposed to let me see his own power as a magnetiser, in an experiment on this patient. The young man consenting, the parties were soon prepared. M. C---- began by telling me, that he would, by _a transfusion of his will_, into the body of the patient, compel him to sit still, although his own desire should be to rise. In order to achieve this, he placed himself before the young man and threw off the fluid from his fingers' ends, which he kept in a cluster, by constant forward gestures of the arms. Sometimes he held the fingers pointed at some particular part of the body, the heart in preference, though the brain would have been more poetical. The young man certainly did not rise; neither did I, nor any one else in the room. As this experiment appeared so satisfactory to everybody else, I was almost ashamed to distrust it, easy as it really seemed to sit still, with a man flourishing his fingers before one's eyes. I proposed that the doctor should see if he could pin me down, in this invisible fashion, but this he frankly admitted he did not think he could do _so soon_, though he foresaw I would become a firm believer in the existence of animal magnetism, ere long, and a public supporter of its wonders. In time, he did not doubt his power to work the same miracle on me. He then varied the experiment, by making the young man raise his arm _contrary_ to his wishes. The same process was repealed, all the fluid being directed at the arm, which, after a severe trial, was slowly raised, until it pointed forward like a finger-board. After this he was made to stand up, in spite of himself. This was the hardest affair of all, the doctor throwing off the fluid in handfuls; the magnetised refusing for some time to budge an inch. At length he suddenly stood up, and seemed to draw his breath like one who finally yields after a strong trial of his physical force. Nothing, certainly, is easier than for a young man to sit still and to stand up, pretending that he strives internally to resist the desire to do either. Still, if you ask me, if I think this was simple collusion, I hardly know what to answer. It is the easiest solution, and yet it did not strike me as being the true one. I never saw less of the appearance of deception than in the air of this young man; his face, deportment, and acts being those of a person in sober earnest. He made no professions, was extremely modest, and really seemed anxious not to have the experiments tried. To my question, if he resisted the will of M. C----, he answered, as much as he could, and said, that when he rose, he did it because he could not help himself. I confess myself disposed to believe in his sincerity and good faith.
