Our study of her on the mental side led us to denominate her as having fair general ability. She had had poor educational advantages. We noted much irregularity on work on tests. She did comparatively poorly on anything that called for careful attention and concentration. This was especially notable when she was dealing with abstractions or situations to be mentally represented. Although she could do arithmetic up to simple division she made a bad failure in the continued process of subtraction as given in the Kraepelin test of taking 8's from 100. In the work on the Code, Test XI, she found it altogether impossible to keep her mind concentrated. In tests where perceptions were largely brought into play she did very well. We noticed that she was possessed of a very dramatic manner. She sighed frequently as she worked. She was very nervous, continually moving her hands and tapping the table. She was quite satisfied with her superficial efforts. It was very curious that we, as well as others, were able to note her apparent sincere belief in her own statements about her family. As she made them she looked the interviewer straight in the eyes; there was not a hint of evasiveness. Her result on the ``Aussage'' (Test VI) was very meager. She only recalled 10 details of the picture. On cross- examination she gave correctly 14 more items and was wrong on 3 of them. She accepted only 2 out of 5 suggestions offered and these were the most probable ones. A full family history was never to be obtained. The best that we came ultimately to know was that her father and mother had been long dead and she had lived in institutions for years, then with a relative who was not at all a good person, and then with her brother and sister, whom she bitterly accused. These were people in decidedly poor circumstances and living in very congested quarters. Indeed, we were inclined to believe, finally, that crowded housing conditions with the necessary unfortunate familiarity with sex affairs and the like was largely responsible for her trouble. A few months prior to these events she had become acquainted with a girl who had drawn her into running away from home a few nights. During her unsettled home life she had seen a good deal of immorality in other houses, but had not been immoral herself. Conditions of squalor surrounded the whole situation.
