able to stir. The gouty man felt his pains diminish rapidly, and was quite easy for nine hours, until he went to bed, when the twitching began again. On the following day the real tractors were applied to all the patients, when they described their symptoms in nearly the same terms.
To make still more sure, the experiment was tried in the Bristol infirmary, a few weeks afterwards, on a man who had a rheumatic affection in the shoulder, so severe as to incapacitate him from lifting his hand from his knee. The fictitious tractors were brought and applied to the afflicted part, one of the physicians, to add solemnity to the scene, drawing a stop-watch from his pocket to calculate the time exactly, while another, with a pen in his hand, sat down to write the change of symptoms from minute to minute as they occurred. In less than four minutes the man felt so much relieved, that he lifted his hand several inches without any pain in the shoulder!
An account of these matters was published by Dr. Haygarth, in a small volume entitled, Of the Imagination, as a Cause and Cure of Disorders, exemplified by fictitious Tractors. The exposure was a coup de grace to the system of Mr. Perkins. His friends and patrons, still unwilling to confess that they had been deceived, tried the tractors upon sheep, cows, and horses, alleging that the animals received benefit from the metallic plates, but none at all from the wooden ones. But they found nobody to believe them; the Perkinean institution fell into neglect; and Perkins made his exit from England, carrying with him about ten thousand pounds, to soothe his declining years in the good city of Pennsylvania.
Thus was magnetism laughed out of England for a time. In France the revolution left men no leisure for studying it. The Sociétés de l'Harmonie of Strasbourg, and other great towns lingered for a while, till sterner matters occupying men's attention, they were one after the other abandoned, both by pupils and professors. The system, thus driven from the first two nations of Europe, took refuge among the dreamy philosophers of Germany. There the wonders of the magnetic sleep grew more and more wonderful every day; the patients acquired the gift of prophecy; their vision extended over all the surface of the globe; they could hear and see with their toes and fingers, and read unknown languages, and understand them too, by merely having the book placed on their stomachs. Ignorant peasants, when once entranced by the grand mesmeric fluid, could spout philosophy diviner than Plato ever wrote, descant upon the mysteries of the mind with more eloquence and truth than the profoundest metaphysicians the world ever saw, and solve knotty points of di-
