Curry, who suffered from this symptom to such a degree that he distinguished every object in a completely darkened room with perfect ease. In somnambulists, however, the eyes are generally closed or violently turned up; and in the rare cases in which they are open, they evidently see nothing. It is, besides, well established that people thus affected have continued to read, to play on instruments, and even to write after they had fallen sound asleep, and without ever opening their eyes. The sensitiveness of the retina could here not avail much. A case is mentioned of a father who rose at night, took his child from the cradle, and with wide open eyes carried it up and down the room, seeing nothing, and in such a state of utter unconsciousness that his wife, walking by his side, could safely draw all his secrets from him without his becoming aware of the process or remembering it the next morning. At the age of forty-five he ceased to walk in his sleep, but, instead, had prophetic dreams which revealed to him the occurrences of the following day and later future events. (_Heer, Observ._) Gassendi (_Phys._, l. viii. ch. 8) mentions a young man, living in Provence, who rose in his sleep, dressed, drew wine in the cellar, wrote up the accounts, and in the darkest night never touched objects that were in his way. If he returned quietly to his bed, he slept well, and strangely enough, recalled everything he had done in the night; but if he was suddenly aroused in the cellar or in the street, he was seized with violent trembling and palpitations of the heart. At times he saw but imperfectly; then he fancied he had risen before daybreak, and lit a lamp. The _Encyclopédie Méthodique_ reports the case of a young priest who wrote his sermons at night, and with closed eyes, and then read each page aloud, correcting and improving what he had written. A sheet of paper held between his eyes and his manuscript did not disturb him; nor did he become aware of it if the latter was removed and blank paper was substituted; in this case he wrote the corrections precisely where they would have been inserted in the text. Macnish mentions ("On Sleep," p. 148) the curious case of an innkeeper in Germany, a huge mass of flesh, who fell asleep at all times and in all places, but who, when this happened while he was playing cards, nevertheless continued to follow suit, as if he could see what was led. In 1832, when he was barely 50 years old, he literally fell asleep, paralysis killing him instantly during one of these attacks of sleep. The same author mentions somnambulists who in their sleep walked to the sea-shore and swam for some distance without being waked, and the case of a Norwegian who during his paroxysms took a boat and rowed himself about for some time. He was cured of his affection by a tub full of water, which was so placed that he had to step into it when leaving his bed. In Scotland a peasant discovered from below the nest of a
