Bessie was given a wide range of mental tests, with the result that we classified her as being well up to the ordinary in ability. Indeed, considering her poor school advantages through frequent changes of residence she did very well in the subjects covered by formal education. Her memory processes and ability to testify correctly--in which we were naturally most interested--seemed, so far as we were able to test them, quite normal. Of a standard passage about a fire (Test XII), which she read once to herself, she recalled 17 out of the 20 items. A passage containing 12 main details (Test XIII), which was read to her in the usual way four times, she recalled with 2 details omitted. The ``Aussage'' test (Test VI) was done very well indeed, with 17 items of the picture given correctly on free recital, and 5 rejections out of the 7 suggestions proffered. Bessie's conversation was fluent and coherent, her range of information was good. She showed fondness for the dramatic statement. Her mother died in the old country when she was about four years old, and her father had immediately come to America, but had never established a home of his own. For the last nine months Bessie had been living with a woman, Mrs. S., who was deeply interested in her. Previously to this she roomed for about six months with her father and brother, and prior to that time she had been placed about in different homes by her father. After some months with Mrs. S. she complained of local pain and irritation. When taken to a physician, she said her father was accustomed to touch her, and her story involved incest by both her father and brother. After others had become interested in her case, the matter was turned into the hands of the police. It was notable that during this period Bessie's love of the dramatic was being fostered by her newly found woman friend, who was providing her with lessons in dramatic reading and taking her extremely frequently to moving picture shows and theatres. When first seen by us, Bessie reiterated her story of sexual relations with her father and brother. As she had done with others, and with the judge, she went into almost convincing details. Her knowledge of such relationships was apparently complete. She informed us that she had caught ``an awful disease'' from her father. She said that while rooming with them her sexual relations with her father and brother were nightly occurrences. They all slept in one bed.
