For the first few days after the delivery, she was fussy with the nurse so that two in succession had to be discharged. On the fifth day she woke up and seeing a nurse lying on the couch beside her bed thought the latter was colored. On the seventh day she had a dream in which she thought she “nearly died in childbirth.” Then she began to talk of dying for her baby or of having two babies, of dying herself and rising again after Easter Sunday. She became antagonistic to her husband and with this excited and confused so that she was taken to the Observation Pavilion. On _admission_ she looked pale and exhausted, had a slight temporary fever and a coated tongue. Her orientation was usually vague but sometimes she gave fair answers. Her verbal productions were rather fragmentary and with the exception of some repetitions there did not seem to be any special topics which dominated her train of thought. For some days the great weakness and the slight fever continued, and then, as it gradually cleared up, there came a change in her mental condition that settled into the state which characterized the rest of her psychosis. She talked less and was often quite inactive, frequently lying with her eyes closed for long periods, or sat or stood about. Such movements as she made were slow and languid. Her expression was either blank, absorbed, or gave the appearance of peculiar appealing perplexity. This last was not infrequently associated with a rather sheepish smile. She was never resistive and always ate and slept well. With the exception of a few times she did not soil herself. The most interesting feature of her mood reaction was that in a general setting of a slight perplexity there appeared at times and evidently associated with definite ideas, changes in her emotional state. Sometimes this was a matter of distress or of mild ecstasy, sometimes she became markedly blocked. There was at no time any frank elation, but often an appropriate smile, that is, appropriate to the situation and to the thought to which she was giving expression at the time. Then, rarely, there were sudden bursts of peculiar conduct, such as throwing herself on the floor or running down the hall. When questioned as to her motive for these acts, she would flush, look perplexed and apparently be unable to explain them.
