bishop of Bourdeaux mentions a similar case of a student, who got up to compose a sermon while asleep, wrote it correctly, read it over from one end to the other, or at least appeared to read it, made corrections on it, scratched out lines, and substituted others, put in its place a word which had been omitted, composed music, wrote it accurately down, and performed other things equally surprising. Dr. Gall takes notice of a miller, who was in the habit of getting up every night and attending to his usual avocations at the mill, then returning to bed: on awaking in the morning, he recollected nothing of what passed during the night. Martinet speaks of a saddler who was accustomed to rise in his sleep and work at his trade; and Dr. Pritchard of a farmer who got out of bed, dressed himself, saddled his horse, and rode to the market, being all the while asleep. Dr. Blacklock, on one occasion, rose from bed, to which he had retired at an early hour, came into the room where his family were assembled, conversed with them, and afterwards entertained them with a pleasant song, without any of them suspecting he was asleep, and without his retaining, after he awoke, the least recollection of what he had done. It is a singular, yet well authenticated fact, that in the disastrous retreat of Sir John Moore, many of the soldiers fell asleep, yet continued to march along with their comrades.
"The stories related of sleep-walkers are, indeed, of so extraordinary a kind, that they would almost seem fictitious, were they not supported by the most incontrovertible evidence. To walk on the house-top, to scale precipices, and descend to the bottom of frightful ravines, are common exploits with the somnambulist; and he performs them with a facility far beyond the power of any man who is completely awake.
"Somnambulism, as well as lunacy, sometimes bestows supernatural strength upon the individual. Mr. Dubrie, a musician in Bath, affords an instance of this kind. One Sunday, while awake, he attempted in vain to force open the window of his bedroom, which chanced to be nailed down; but having got up in his sleep, he repeated the attempt successfully, and threw himself out, by which he unfortunately broke his leg.
"Sleep-walking is sometimes periodical. Martinet describes the case of a watchmaker's apprentice who had an attack of it every fortnight. In this state, though insensible to all external impressions, he would perform his work with his usual accuracy, and was always astonished 'on awaking, at the progress he had made. The paroxysm began with a sense of heat in the epigastrium extending to the head, followed by confusion of ideas and complete insensibility, the eyes remaining open With a fixed and vacant stare. This case, which undoubtedly originated
