When the patient was able later to give a retrospective account of the onset, she claimed that for some months before this incident she saw that her brother was losing his mind. She worried about this as well as about her work, and felt worn out. She said that when the brother tried to throw himself under the train she was terrified and could not speak or move, and that her mind got upset at once, “I lost my memory.” The others forgot her and left her alone on the platform. Strangers put her on another train and she knew nothing until she arrived at home. The mother added that at the time when the incident with the brother happened, the patient was menstruating and that this ceased at once. At home she sat about inactive and did not seem even to worry. Whenever any one asked her about her brother she replied that he was dead. For two weeks before admission she said she was rich, that she owned all the property around. She also said she was married to Mattie S. In this connection the mother says that a foolish neighborwoman, the mother of Mattie S., told the patient since her sickness, by way of encouragement, that she should marry her son (the man mentioned). Finally, the patient also expressed the idea that her mother was a stranger, that her real mother was dead. At the _Observation Pavilion_ she was described as wandering about in a perplexed manner, restless, resistive, answering few questions and in a low tone. She said things were “changed,” also that she was married to S. _Under Observation:_ 1. For about ten days the patient’s condition may be described as follows: The most striking feature was a certain restlessness with insistence on going out, with complaints that this and that had been done to her and with senseless struggling when interfered with. But all the motions were slow, the whole restlessness aimless and impulsive. Although the facial expression was somewhat perplexed, it changed remarkably little, and whenever asked whether she felt worried or anxious she denied it, and, indeed, there was only a suggestion of perplexity in her face.
