found himself in a company of table-movers at the house of Lord William Cowper, the son-in-law of Lord Palmerston. To prove his faith he crept under the heavy dining-table, resting with his full weight on one of the three solid feet and grasping the other two firmly with his hands. The wood began to emit low, electric sounds, then came louder noises as when furniture cracks in extremely dry weather, and finally the table began to move. Reichenbach did his best to prevent the movement, but the table rushed down the room, dragging the unlucky baron with it, to the intense amusement of all the persons present. The German savant maintains that this power, possessed only by the privileged few who are peculiarly sensitive, emanates from the tips of the fingers, becomes luminous in the dark, and acts like a lever upon all obstacles that come in its way. As the existence of Od is established beyond all doubt, and its effects are admitted by all who have studied the subject, we are forced to look upon it as at least one of the mysterious elements of modern magic. The Od is, as far as we know, a magnetic force; for as soon as certain persons are magnetized they become conscious of peculiar sensations, heat or cold, headache or other pains, and, if predisposed, of a startling increase of power in all their senses. They see lights of every kind, can distinguish even minute objects in a dark room, and behold beautiful white flames upon the poles of magnets. Reichenbach obtained, as he believed, two remarkable results from these first phenomena. He concluded that polar lights, aurora boreales, etc., were identical with the magnetic light of the earth, and he discovered that sensitive, sickly persons, who were peculiarly susceptible to magnetic influences, ought to lie with the head to the north, and the feet to the south in order to obtain refreshing sleep. The next step was an effort to identify the Od with animal magnetism; Reichenbach found that cataleptic patients who perceived the presence of magnets with exquisite accuracy, and followed them like mesmerized persons, were affected alike by his own hands or those of other perfectly sound, but strongly magnetic men. He could attract such unfortunate persons by his outstretched fingers, and force them to follow him in a state of unconsciousness wherever he led them. According to his theory, the two sides of man are of opposite electric nature and a magnetic current passes continually from one side to the other; sensitive persons though blind-folded, know perfectly well on which side they approach others.
