“A young man, named A. F., about twenty years of age, was living with his parents in great apparent harmony, his father and himself being alike distinguished for their great fondness for hunting. In consequence of danger from nocturnal attacks, they were in the habit of taking their arms with them into their chambers when they went to bed. On the afternoon of September 1st, 1839, the father and son having just returned from hunting, their danger became the subject of particular conversation. The next day the hunting was repeated, and on their return, after taking supper with every evidence of good feeling, they retired for the night, the son to his own room, and his father and mother to theirs. Both father and son took their loaded arms with them. At one o’clock the father got up to go into the entry, and on his return jarred against the door, on which the son instantly sprang up, seized his gun, and discharged it at his father, giving him a fatal wound in the breast, at the same time exclaiming, ‘Dog, what do you want here?’ The father immediately fell to the ground; and the son, then recognizing him, sank on the floor, crying, ‘Oh, Jesus! it is my father!’ “The evidence was that the whole family were subject to great restlessness in their sleep, and that the defendant in particular was affected with a tendency to be easily distressed by dreams, which lasted for about five minutes, on waking, before their effect was entirely dissipated. His own version of the affair was: ‘I must have fired the gun in my sleep; it was moonshine, and we were accustomed to talk and walk in our sleep. I recollect hearing something jar; I jumped up, seized my gun, and fired when I heard the noise; I recollect seeing nothing, nor am I conscious of having spoken. The night was so bright that everything could have been seen. I must have been under the delusion that thieves had broken in.’ The opinion of the medical experts was, that the act was committed during the condition of sleep drunkenness, and that, accordingly, it was not that of a free and responsible agent.” The same authors quote the following case of Dr. Meister, from Herke’s Zeitschrift:
