trade; and such was the infatuation of the people to be witnesses of their strange manipulations, that, at times, upwards of three thousand persons crowded around their house at Hammersmith, unable to gain admission. The tickets sold at prices varying from one to three guineas. Loutherbourg performed his cures by the touch, after the manner of Valentine Greatraks, and finally pretended to a Divine mission. An account of his miracles, as they were called, was published in 1789, entitled A List of New Cures performed by Mr. and Mrs. de Loutherbourg of Hammersmith Terrace, without Medicine; by a Lover of the Lamb of God. Dedicated to his Grace the Archbishop of Canterbury.

This “Lover of the Lamb of God” was a half-crazy old woman, named Mary Pratt, who conceived for Mr. and Mrs. de Loutherbourg a veneration which almost prompted her to worship them. She chose for the motto of her pamphlet a verse in the thirteenth chapter of the Acts of the Apostles: “Behold, ye despisers, and wonder and perish! for I will work a work in your days which ye shall not believe though a man declare it unto you.” Attempting to give a religious character to the cures of the painter, she thought a woman was the proper person to make them known, since the apostle had declared that a man should not be able to conquer the incredulity of the people. She stated that, from Christmas 1788 to July 1789, De Loutherbourg and his wife had cured two thousand people, “having been made proper recipients to receive Divine manuductions; which heavenly and Divine influx, coming from the radix God, his Divine Majesty had most graciously bestowed upon them to diffuse healing to all, be they deaf, dumb, blind, lame, or halt.”

In her dedication to the Archbishop of Canterbury, she implored him to compose a new form of prayer to be used in all churches and chapels, that nothing might impede this inestimable gift from having its due course. She further entreated all the magistrates and men of authority in the land to wait on Mr. and Mrs. de Loutherbourg, to consult with them on the immediate erection of a large hospital, with a pool of Bethesda attached to it. All the magnetisers were scandalised at the preposterous jabber of this old woman, and De Loutherbourg appears to have left London to avoid her; continuing, however, in conjunction with his wife, the fantastic tricks which had turned the brain of this poor fanatic, and deluded many others who pretended to more sense than she had.

From this period until 1798, magnetism excited little or no attention in England. An attempt to revive the doctrine was made in that year, but it was in the shape of mineral rather than of animal magnetism. One Benjamin Douglas Perkins, an American, practising as a surgeon in Leicestersquare, invented and took out a patent for the celebrated “Metallic Tractors.” He pretended that these tractors, which were two small pieces of metal strongly magnetised, something resembling the steel plates which were first brought into notice by Father Hell, would cure gout, rheumatism, palsy, and in fact, almost every disease the human frame was subject to, if applied externally to the afflicted part, and moved about gently, touching the surface only. The most wonderful stories soon obtained general circulation, and the press groaned with pamphlets, all vaunting the curative effects of the tractors, which were sold at five guineas the pair. Perkins gained money rapidly. Gouty subjects forgot their pains in the presence of this new remedy; the rheumatism fled at its approach; and toothache, which is often cured by the mere sight of a dentist, vanished before Perkins and his marvellous steel plates. The benevolent Quakers, of whose body he was a member, warmly patronised the invention. Desirous that the poor, who could not afford to pay Mr. Perkins five guineas, or even five shillings, for his tractors, should also share in the benefits of that sublime discovery, they subscribed a large sum, and built an hospital, called the “Perkinean Institution,” in which all comers might be magnetised free of cost. In the course of a few months they were in very general use, and their lucky inventor in possession of five thousand pounds.

Dr. Haygarth, an eminent physician at Bath, recollecting the influence of imagination in the cure of disease, hit upon an expedient to try the real value of the tractors. Perkins’s cures were too well established to be doubted; and Dr. Haygarth, without gainsaying them, quietly, but in the face of numerous witnesses, exposed the delusion under which people laboured with respect to the curative medium. He suggested to Dr. Falconer that they should make wooden tractors, paint them to resemble the steel ones, and see if the very same effects would not be produced. Five patients were chosen from the hospital in Bath, upon whom to operate. Four of them suffered severely from chronic rheumatism in the ankle, knee,
