nevertheless, seemed very important to me. Many weeks later I had an opportunity to speak to the patient's mother, and from her I learned that her daughter had been a very exceptional child. When only two years old she would sit with her back to an open cupboard door for hours and rhythmically beat her head against the door[2]—to the distraction of the household. A little later, instead of playing as other children, she began to bore a hole with her finger in the plaster of the wall of the house. She did this with little turning and scraping movements, and kept herself busy at this occupation for hours. She was a complete puzzle to her parents. From her fourth year she practised onanism. It is evident that in this early infantile activity the preliminary stage of the later trouble may be found. The especially remarkable features in this case are, first, that the child did not carry out the action on its own body, and, secondly, the assiduity with which it carried on the action.[3] One is tempted to bring these two facts into a causal relationship and to say, because the child does not accomplish this action on her own body, perhaps that is the reason of the assiduity, for by boring into the wall she never arrives at the same satisfaction as if she executed the activity onanistically on her own body.
The very evident onanistic boring of the patient can be traced back to a very early stage of childhood, which is prior to the period of local onanism. That time is still psychologically very obscure, because individual reproductions and memories are lacking to a great extent, the same as among animals. The race characteristics (manner of life) predominate during the entire life of the animal,
