The first case is that of an unmarried woman of twenty-eight, who walked in her sleep first in her sixth year and the second time when she was nine years old. "I got up when the full moon was shining, climbed over a chair upon the piano and intended to go to the window to unfasten it. Just then my father awoke and struck me hard on my buttocks, upon which I went back and again fell asleep. I often arose, went to each bed, that of the parents and those of the brothers and sisters, looked at them and went back again. Between sixteen and seventeen years old, when my periods first occurred, the sleep walking stopped." She adds later: "I frequently as a child spoke out in my sleep. My nose began to bleed when I was walking on the street and the sun shone upon me. After this the sleep walking improved. I always clung affectionately to my parents and brothers and sisters, and never received a blow except in that one instance by my father."--"Which you took rather as a caress, than as a blow for punishment." In this case also the sleep walker plays sometimes the rôle of the mother, who satisfies herself that her dear ones are asleep. Moreover a period of talking in the sleep precedes the wandering by moonlight. It is noteworthy that the sleep walking is intercepted by a caressing blow from the father and ceases altogether when menstruation sets in. Also earlier nosebleed had a beneficial effect. The second case is that of a forty-year-old hysteric, who in her marriage remained completely anesthetic sexually, although her husband was thoroughly sympathetic to her and very potent. Her father's favorite child, she strove in vain in early childhood for the affection of the mother, who on her part also suffered severely from hysteria, with screaming fits, incessant tremor of the head and hands and a host of nervous afflictions. This mother's daughters had all of them always an extraordinary passion for muscular activity with apparently great satisfaction in it. They were among other things distinguished swimmers and enthusiastic dancers. My patient besides could never tire of walking for hours at a time.
