I copy the above particulars from Dr Foissac's "_Rapports et Discussions de l'Academie Royale de Medicine sur le Magnetisme Animal_."--Paris, 1833. "My friend, Dr Warren of Boston, informed me that, being at Paris, he had asked M. Jules Cloquet if the story were true. M. Cloquet answered, "Perfectly." "Then why," said Dr Warren, "have you not repeated the practice?" M. Cloquet replied, "that he had not dared: that the prejudice against mesmerism was so strong at Paris, that he probably would have lost his reputation and his income by so doing." Here, then, we discover two purposes of partial, indeed, but signal utility, compassable by the induction of trance, at the very outset of our inquiry into its utility. It will appear by-and-by that this resource promises to afford yet farther assistance to the physician. In the mean time, let us look at a relation of the subject which may appear more interesting to the general reader. It has been mentioned that, in ordinary trance, the relations of consciousness to the nervous system are altered; that the laws of sensation and perception are suspended, or temporarily changed; that the mind appears to gain new powers. For a long time we had to trust to the chance turning up of cases of spontaneous trance, in the experience of physicians of observation, for any light we could hope would be thrown on those extraordinary phenomena. Now we possess around us, on every side, adequate opportunities for completely elucidating these events, if we please to employ them. The philosopher, when his speculations suggest a new question to be put, can summon the attendance of a trance, as easily as the Jupiter of the Iliad summoned a dream. Or, looking out for two or three cases to which the induction of trance may be beneficial, the physician may have in his house subjects for perpetual reference and daily experiment. A gentleman with whom I have long been well acquainted, for many years Chairman of the Quarter Sessions in a northern county, of which the last year he was High Sheriff, has, like M. de Puysegur, amused some of his leisure hours, and benevolently done not a little good, by taking the trouble of mesmerising invalids, whom he has thus restored to health. In constant correspondence with, and occasionally having the pleasure of seeing this gentleman, I have learned from him the common course in which the new powers of the mind which belong to trance are developed under its artificial induction. The sketch which I propose to give of this subject will be taken on his descriptions, which, I should observe, tally in all essential points with what I meet with in French and German authors. The little that I have myself seen of the matter, I will mention preliminarily; the most astounding things, it appears to me safer to shelter under the authority of Petetin, who, towards the close of the last century, _in ignorance of mesmerism_, described these phenomena _as they came before him spontaneously in catalepsy_.
