Afterwards, when a patient has by use become highly sensitive to Od, and disposed to fall into trance, I have myself, by making passes _in the next room_, succeeded in producing the sleep. And I have seen, with open doors, mesmeric effects produced by passes at the distance of ninety feet. But with persons rendered through use extremely susceptible of mesmeric impression, an effect may be produced by the habitual mesmeriser of the patient at almost unlimited distances. The following instance is given by Dr. Foissac in his valuable work on mesmerism, entitled _Rapports et Discussions sur le Magnétisme Animal_, (Paris, 1838.) Dr. Foissac speaks, in the first person, of an experiment made by himself on a patient of the name of Paul Villagrand, whom he had been in the habit of mesmerising in the usual way at Paris, where both resided. “In the course of the June ensuing,” says Dr. Foissac, “Paul expressed the wish to pass some days in his native place, Magnac-Laval, Haute Vienne. I provided him with the means, and proposed to turn his journey to scientific account by attempting to entrance him at the distance of a hundred leagues. He was not to know my intention before the time came; but on the 2d of July, at half-past five P.M., his father was to give him a note from me, which ran thus—‘I am magnetising you at this moment; I will awake you when you have had a quarter of an hour’s sleep.’ M. Villagrand made the success of the experiment the more decisive by not handing over my letter to his son, and so disregarding my instructions. Nevertheless, at ten minutes before six, Paul being in the midst of his family, experienced a sensation of heat, and considerable uneasiness. His shirt was wet through with perspiration; he wished to retire to his room; but they detained him. In a few minutes he was entranced. In this state he astonished the persons present, by reading with his eyes shut several lines of a book taken at hazard from the library, and by telling the hour upon a watch they held to him. He awoke in a quarter of an hour.” One naturally doubts whether the physical influence of the Od force can extend to this enormous distance; whether the agency ought not to be regarded as purely psychical; whether, in short, the will of the speaker may not have been the exclusive agent employed.
