in some diseased state of the brain, terminated in epilepsy. Dr. Gall relates that he saw at Berlin a young man, sixteen years of age, who had, from time to time, very extraordinary fits. He moved about unconsciously in bed, and had no perception of anything that was done to him; at last he would jump out of bed, and walk with rapid steps about the room, his eyes being fixed and open. Several obstacles which were placed by Dr. Gall in his way, he either removed or cautiously avoided. He then threw himself suddenly again upon the bed, moved about for some time, and finished by jumping up awake, not a little surprised at the number of curious people about him.
"The facility with which somnambulists are awakened from the paroxysms, differs extremely in different cases. One man is aroused by being gently touched or called upon, by a flash of light, by stumbling in his peregrinations, or by setting his foot in water. Another remains so heavily asleep, that it is necessary to shout loudly, to shake him with violence, and make use of other excitations equally powerful. In this condition, when the sense of vision chances to be dormant, it is curious to look at his eyes. Sometimes they are shut; at other times wide open; and when the latter is the case, they are observed to be fixed and inexpressive, "without speculation," or energy, while pupil is contracted, as in the case of perfect sleep.
"It is not always safe to arouse a sleep-walker; and many cases of the fatal effects thence arising, have been detailed by authors. Nor is it at all unlikely that a person, even of strong nerves, might be violently agitated by awaking in a situation so different from that in which he lay down. Among other examples, that of a young lady, who was addicted to this affection, may be mentioned. Knowing her failing, her friends made a point of locking the door, and securing the window of her chamber in such a manner that she could not possibly get out. One night, these precautions were unfortunately overlooked, and, in a paroxysm of somnambulism, she walked into the garden behind the house. While there, she was recognised by some of the family, who were warned by the noise she made on opening the door, and they followed and awoke her; but such was the effect produced upon her nervous system, that she almost instantly expired."
Having adduced these cases, in order to justify the introduction of the scenes described in the following—not too profoundly-written pages—I have only to beg of those who read the work as a whole, to bear in mind that it originally appeared in monthly parts.
