The many astute tricks played by animal magnetisers, and frequently detected, naturally induced most persons to doubt the veracity of these experiments; but when we find that they were witnessed by seventy-eight medical men, most of them decidedly hostile to magnetism, and sixty-three intelligent individuals not belonging to the profession, and in every respect disinterested, what are we to say?--perhaps, exclaim with Hamlet, There are more things in heaven and earth, Horatio, Than are dreamt of in your philosophy! I cannot better conclude this article than by the following quotation from Dr. Pritchard's valuable work:[8] "There is an obvious relation between the state of the faculties in somnambulism and that which exists during dreams. It is indeed probable that somnambulism is dreaming in a manner so modified, that the will recovers its usual power over muscular motion, and likewise becomes endued with a peculiar control over the organs of sense and perception. This power, which gives rise to the most curious phenomena of somnambulism, is of such a kind, that, while the senses are in general obscured, as in sleep, and all other objects are unperceived, the somnambulator manifests a faculty of seeing, feeling, or otherwise discovering those particular objects of which he is in pursuit, towards which his attention is by inward movement directed, or with which the internal operations of his mind bring him into relation. As in dreams, so likewise in somnambulism the individual is intent on the pursuit of objects towards which his mind had been previously directed in a powerful manner, and his attention strongly roused; he is in both states impelled by habit, under the influence of which he repeats the routine of his daily observances. A somnambulator is a dreamer who is able to act his dreams." MEDICAL POWERS OF MUSIC.
