Much emaciated, abdomen concave, but on pressing it the tumour can be felt at the brim of the pelvis. On opening the abdominal cavity, the mass was found adhering firmly to the neighbouring intestines, and on the right side to the soft linings of the pelvis: it was of an irregular form, with spots of livid vascularity in different parts: on the upper and left side of it, fetid purulent matter was seen exuding from a small orifice. The uterus was below, its fundus pushed over to the left side. On separating its adhesions, and attempting to raise the sac from the pelvis, the half-softened parietes gave way, and the decomposed putty-like mass of the foetus became visible; the cranial bones were at the left side; the feet were still distinct on the right side; the whole was immersed in a quantity of thick fetid pus, and there were no traces either of umbilical cord or placenta. Cases of ventral pregnancy have been recorded where the child has remained in the mother's abdomen without producing any dangerous symptoms, and where she has again become pregnant in the natural way. The earliest instance of this sort was recorded so long ago as by Albucasis. A very interesting case of this nature is described by Dr. Bard of New York. (_Med. Obs. and Inquiries_, vol. ii. p. 369.) It was the patient's second pregnancy; at the end of nine months she had pains, which after a time went off; the tumour gradually diminished somewhat, and in about five months after she conceived again, and in due time was delivered, after an easy labour, of a healthy child. "Five days after delivery she was seized with a violent fever, a purging, suppression, pain in the tumour, and _profuse fetid sweats_:" an abscess formed in the abdomen, which was opened, and a vast quantity of extremely fetid matter was discharged; the opening was enlarged, and a foetus of the full size was extracted. Dr. Bard "imagined the placenta and funis umbilicalis were dissolved in the pus, of which there was a great quantity." It becomes a question of deep interest whether it be really possible to save the patient and the child in cases of ventral pregnancy, by performing gastrotomy. The separation of the placenta from the walls of the cyst can only be effected with much difficulty and hazard; indeed, we are at a loss to conceive how it can be removed with any degree of safety, where the child has been found alive. The attachment in these cases was more than usually firm, and it has been left to undergo that process of solution which has been described in Dr. Bard's case. In all the cases where gastrotomy has been performed some time after the child's death, little or no trace of the placenta has been found, but in its place a quantity of ill-conditioned purulent matter, which was excessively fetid.
