This case is of especial interest as the right tube and ovary had previously been removed. The ovum found lodgment and had developed in the uterine portion of the stump. History. —Mrs. J. C. O., aged 30, married ten years, had one child 2½ years old. The right Fallopian tube and ovary were removed six years ago. Since that time her health has been good. September 10 last she missed her period but felt continually as if "about to menstruate." November 1 she was taken suddenly with an acute pain in the lower abdomen accompanied by diarrhea, nausea and vomiting. The next day she was better, but had a sore spot and a lump the size of a hen's egg below and to the right of the umbilicus. The physician who attended her paid no attention to it, as he thought it would pass off in a few days.
