Young Hebert, who had gone mad as the result of a wound, regained full consciousness, the higher consciousness, during somnambulism. (Puysegur's _Journal du traitement du jeune Hebert_.) Dr. Teste (_Manuel pratiq. du magnet. anim._) came across madmen who became sane just before death, _i.e._, when consciousness was passing into the astral body. He also mentions a servant girl, quite uneducated and of ordinary intelligence, who nevertheless became a veritable philosopher during mesmeric somnambulism and delivered learned discourses on lofty problems dealing with cosmogony. This proves that the vibratory scale of the finer vehicle extends far beyond that of the physical, and that the soul cannot impress on this latter vehicle all that it knows when functioning in the former. By this we do not mean that it is omniscient as soon as it has left the visible body; this opinion, a current one, is contrary to the law of evolution, and will not bear examination. MANIFESTATIONS OF THE HIGHER CONSCIOUSNESS UNDER THE FORM OF MEMORY. The memory that is lost by the brain is preserved in its entirety by the finer vehicle. A musician, a friend of Hervey's, once heard a remarkable piece of music; he remembered it on awaking, and wrote it down, regarding it as his own inspiration. Many years afterwards, he found it in an old parcel of music where he knew it had been long before; he had totally forgotten it in his normal consciousness. (Hervey's _Dreams_.) Coleridge tells of a servant girl who, when in a state of delirium, would recite long passages of Hebrew which she had formerly heard from the lips of a priest in whose service she had been. In the same way, she would repeat passages from Latin and Greek theological books, which she had heard under the same circumstances; in her normal state, she had no recollection whatever of all this. (Dr. Carpenter's _Mental Physiology_, p. 437, 1881 edition.) Ricard (_Physiol. et Hygiene du Magnet._, p. 183) relates the case of a young man, possessed of an ordinary memory, but who, in somnambulism, could repeat almost word for word a sermon he had heard or a book he had read. Mayo, the physiologist, states that an ignorant young girl, in a state of somnambulism, wrote whole pages of a treatise on astronomy, including figures and calculations, which she had probably read in the _Encyclopaedia Britannica_, for the treatise was afterwards found in that work. (_Truths in Popular Superstitions._) Ladame (_La Nevrose hypnotique_, p. 105) mentions a woman who, having only on one occasion been to the theatre, was able, during somnambulism, to sing the whole of the second act of Meyerbeer's _L'Africaine_, an opera of which she knew nothing whatever in her waking state. During experiments with the inhaling of protoxyde of azote, H. Davy said that normal consciousness disappeared, and was followed by a wonderful power of recalling past events. (Hibbert's _Philosophy of Apparitions_, p. 162.)
