Uterus was not felt to be at all enlarged, but the os was patulous. There was an enlargement to the right of the uterus. This could be felt both externally and through the vagina; was of an irregular outline, and quite tense and tender upon pressure. A sound was introduced into the uterus and passed in about three inches and was deflected to the left quite perceptibly. It did not appear quite certain that there was nothing in the uterus, and in view of the history of the case it seemed justifiable to explore the cavity. Accordingly a good sized sponge tent was introduced and allowed to remain twenty-four hours, when it was removed and the uterine cavity explored with purely negative results. The patient had now been under observation over a week, and attempts made to improve her general condition with tonics and nutritious diet, but without success. Her temperature continued about 101° most of the time. A positive diagnosis had not been made, though it seemed that about everything could be excluded except extra-uterine pregnancy. At this juncture Dr. W. J. Scott was asked to see the patient. He did so and made a very careful examination, and gave it as his opinion the case was one of extra-uterine pregnancy. The next day Dr. Dudley P. Allen was called in consultation with Dr. Scott and myself. Dr. Allen's examination was careful and exhaustive, and at its close he gave it as his opinion that while there were some obscure points, the most probable conclusion was that the case was one of extra-uterine fœtation.
