in a way which seemed to justify her belief. Her breasts and abdomen were the chief seats of this overgrowth. The menses did not return, her pallor increased; the child was felt, and every preparation made for delivery. At the eighth month a physician made an examination and assured her of the absence of pregnancy. A second medical opinion confirmed the first, and the tenth month found her of immense size and still positive as to her condition. At the twelfth month her menstrual flow returned, and she became sure it was the early sign of labor. When it passed over she became convinced of her error, and at once dropped weight at the rate of half a pound a day despite every effort to limit the rate of this remarkable loss. At the end of two months she had parted with fifty pounds and was, on the whole, less anemic. At this stage I was consulted by letter, as the woman had become exceedingly hysteric. This briefly stated case, which occurred many years ago, is a fair illustration of my thesis. "Another instance I saw when in general practice. A lady who had several children and suffered much in her pregnancies passed five years without becoming impregnated. Then she missed a period, and had, as usual, vomiting. She made some wild efforts to end her supposed pregnancy, and failing, acquiesced in her fate. The menses returned at the ninth month and were presumed to mean labor. Meanwhile she vomited, up to the eighth month, and ate little. Nevertheless, she took on fat so as to make the abdomen and breasts immense and to excite unusual attention. No physician examined her until the supposed labor began, when, of course, the truth came out. She was pleased not to have another child, and in her case, as in all the others known to me, the fat lessened as soon as the mind was satisfied as to the non-existence of pregnancy. As I now recall the facts, this woman was not more than two months in getting rid of the excess of adipose tissue. Dr. Hirst tells me he has met with cases of women taking on fat with cessation of the menses, and in which there was also a steady belief in the existence of pregnancy. He has not so followed up these cases as to know if in them the fat fell away with speed when once the patient was assured that no child existed within her."
