So far as the author is aware, this constitutes the sum of our knowledge in regard to this alleged species of erratic gesta- tion. It ma}^ at once be concluded that, in the cases reported by ]^oel and Mackeprang, the foetus was developed outside of the uterus, but it does not, therefore, follow that the preg- nancy was vaginal. It is to be noticed that in both instances the anterior history is defective. ITeither woman was seen by her medical attendant until immediately before her delivery. We therefore have no account of the development of this tumor in the vagina, l^either are we put in possession of any facts which will enable us to determine by what the product of conception was covered. If an ovum is developed in the vagina, it would, as in peritoneal pregnancy, be destitute of any coverings excepting its own membranes, the amnion and chorion. This would seem to be impossible in the vagina. If the tumors were found covered with mucous membrane, the difficulty is at once solved, and the cases could be placed with certainty in that class of extra-uterine pregnancy, which Dezeimeris has called subperitoneo-pelvic, and which is no- thing more than one of the terminations of tubal conception. This would appear to be the correct explanation of these two interesting observations. The third case cannot be disposed of so easily. In this the development of the placenta in the uterus insured the normal nutrition of the foetus. The results of secondary peritoneal pregnancies have demonstrated the fact, that the presence of heat and moisture, and a continuous regular supply of nutri- ment through the placenta, are all that is needful to insure the complete development of the child. It is proved beyond doubt, that the presence of the liquor amnii is not necessary to preserve its life and to insure its growth, ^or is it necessary that the membranes should preserve their integrity for its protection. It has been proved beyond possibility of doubt, that at an early stage in the pregnancy, the sac may rupture and allow the embryo to escape into the peritoneal cavity, where it is perfectly free excepting its attachment with the umbilical cord.
