The details of Mesmer's early doings are of special value, for in them we may expect to discover the true nature of the man and his system; our knowledge of them is derived mainly from the account, written some thirty-five years after the events, by a not too discerning eyewitness. They give a sufficiently definite picture of his manner and methods. Magnets and electric machines, passes and strokings, fantastic dress and equally fantastic manipulations, he utilized even before he became well known. The method was always the same; calling out pains and paroxysms and crises, and in turn allaying the symptoms thus aroused until the patient was pronounced cured. From the first, too, he was anxious to secure the recognition of authoritative bodies of scientific men. Early in 1775, Mesmer proposed his theory for acceptance to several learned societies, but received no encouragement. His use of magnets (which he probably derived from the astronomer, Hell) had aroused the opposition of his fellow-practitioners, and his professed cure of a protégé of Maria Theresa involved him in a somewhat unseemly dispute, ultimately necessitating his departure from Vienna. In February, 1778, he came to Paris, where he entered upon a remarkable but brief career, terminating somewhat abruptly in 1784. Mesmer has left us a narrative of his doings during the first three of these years--a record devoted almost exclusively to a wearisome account of his controversies with the various learned societies of Paris. He appealed to the French Academy of Sciences and to the Royal Medical Society, announcing a most wonderful physical discovery, to describe which suitable words were as yet lacking. Mesmer wished these societies to sanction his discovery, not to act as judges of its truth, of which he says there can be no reasonable doubt. He offered them a series of dogmatic propositions, setting forth the nature of animal magnetism, and apparently desired the cures to be considered a subordinate part of the issue. He was, however, continuously engaged in curing disease. His most valuable convert was M. Deslon, a member of the Medical Faculty of Paris, a man of considerable influence, who at once espoused Mesmer's cause with unlimited enthusiasm. He invited a dozen of his colleagues to meet Mesmer at dinner, and had read to them an exposition of the system of animal magnetism. The company seem not to have been very deeply impressed; for it was with difficulty that Deslon induced three of them to associate themselves with him in an investigation; and they soon deserted him, when their requests for simple, unambiguous tests and their explanation of the observed effect as due to an overstimulated imagination, were alike disregarded. The point at issue in these tests seems to have been whether Mesmer in his own person possessed an influence or magnetic radiation, which brought him into rapport with his magnetically sensitive subjects; but Mesmer
