_Onset of Psychosis:_ Nine days before admission a young man died in the house where they lived. The next day her mother insisted on the patient and her sister going to the funeral. On coming home the patient complained of being afraid and having a funny feeling. She woke up at 2:30 that night and lit all the gas, for which she could give no explanation. The day following, or a week before admission, she was slow, confused, could not get her clothes together. The next day she was restless and worried, giving a superficial explanation for the latter. She played the piano a great deal. The following day she was fidgety and cried. At 4 p.m. she was put to bed and appeared to fall asleep. At midnight when a priest called she said to him privately that she was all over the world, that she went to the 12th floor of the Metropolitan Building, that she sat down and took the man’s money, $7, and came right away. She recognized the priest. Three days before admission she wanted to stay in bed, kept her eyes closed. When spoken to she would smile but did not open her eyes. She did not pass her urine all day. Her mother then gave her some medicine which the doctor had left. The patient immediately had a peculiar attack in which she heaved her breast, drew her head back, clenched her fists and worked her feet. Saliva escaped from the side of her mouth. This attack lasted some three to five minutes. Her mother then called an ambulance and she was taken to the _Observation Pavilion_. She thought that the ambulance doctor was an uncle, a soldier in the Philippines, of whom she was very fond. There she remained in bed, with all her muscles relaxed, her mouth constantly open, saying nothing and indeed resisting efforts which were made to get her to open her eyes.
