magnetizer points, with all the fidelity and marvelous accuracy of a well-trained dog, finally reaches him and sees him and his surroundings. Nor is the distance a matter of indifference; like the ordinary senses, this new sense also seems to have its laws and its limits, and if the task is too heavy and the distance too great, the perception remains vague and indefinite. Most important of all is the fact that, unlike spiritual visions, magnetism never enables the sleeper to go beyond the limits of our earthly home. On the other hand, time is no more an obstacle than space, and genuine somnambulists have seen past and future events as well as distant scenes. Mistakes, however, occur here as with all our other senses; as healthy persons see amiss or hear amiss, so magnetic sleepers also are not unfrequently mistaken--errors to which they are all the more liable as the impressions received by magic powers have to be translated into the language adapted to ordinary senses. Among somnambulists of this class Alexis is one of the best known, and has left us an account of many experiments in his _Explication du Sommeil Magnétique_. Alexis was once put into magnetic sleep by a friend of Dr. Mayo, and then ordered to go to Boppard, on the Rhine, and look for him; Alexis, after some hesitation, stated that he had found him, and described--although he had never seen him before--his appearance and dress, not only, but also the state of mind in which he was at that moment, all of which proved afterward to be perfectly correct. Alexis declared that his perceptions varied very much in clearness, and that his power to see friends at a distance depended largely on the affection he felt for them. In all instances his magic powers were far inferior to those of his natural senses, although they never misled him, as the latter had done occasionally. In the _Bibliothèque du Magnétisme Animal_ (vii. p. 146), a remarkable case is reported as attested by undoubted authority. The English consul, Baldwin, was, in 1795, visited by an Italian improvisatore, who happened to have a small medicine-chest with him. In the consul's kitchen was a little Arab, a scullion, who suffered of a harassing cough, and whom his master magnetized in order to cure him. While in his sleep the boy saw the medicine-chest, of which he had known nothing before, and selected among the phials one with sugar of agrimonium, which relieved him of his troubles. The Italian, thereupon, asked also to be magnetized; fell promptly asleep, and wrote in this condition, with closed eyes, a poem praising the art of magnetism. Haddock's famous subject, Emma, actually accomplished once the crucial test of all magic phenomena--she proved the value of magnetism in a question of money. In the year 1849 three notes, amounting to £650, had been deposited in a bank, and disappeared in the most unaccountable manner. One of the clerks confessed, that although he had received them,
