Another very singular notion of the power and capabilities of magnetism was entertained at the same time. It was believed that a sympathetic alphabet could be made on the flesh, by means of which persons could correspond with each other, and communicate all their ideas with the rapidity of volition, although thousands of miles apart. From the arms of two persons a piece of flesh was cut, and mutually transplanted, while still warm and bleeding. The piece so severed grew to the new arm on which it was placed; but still retained so close a sympathy with its native limb, that its old possessor was always sensible of any injury done to it. Upon these transplanted pieces were tatooed the letters of the alphabet; so that, when a communication was to be made, either of the persons, though the wide Atlantic rolled between them, had only to prick his arm with a magnetic needle, and straightway his friend received intimation that the telegraph was at work. Whatever letter he pricked on his own arm pained the same letter on the arm of his correspondent.
Contemporary with Sir Kenelm Digby was the no less famous Mr. Valentine Greatraks, who, without mentioning magnetism, or laying claim to any theory, practised upon himself and others a deception much more akin to the animal magnetism of the present day than the mineral magnetism it was then so much the fashion to study. He was the son of an Irish gentleman, of good education and property, in the county of Cork. He fell, at an early age, into a sort of melancholy derangement. After some time he had an impulse, or strange persuasion in his mind, which continued to present itself, whether he were sleeping or waking, that God had given him the power of curing the king’s evil. He mentioned this persuasion to his wife, who very candidly told him that he was a fool. He was not quite sure of this, notwithstanding the high authority from which it came, and determined to make trial of the power that was in him. A few days afterwards, he went to one William Maher, of Saltersbridge, in the parish of Lismore, who was grievously afflicted with the king’s evil in his eyes, cheek, and throat. Upon this man, who was of abundant faith, he laid his hands, stroked him, and prayed
