    diameter, and from one to two lines in depth. The upper concave surface of the cavity formed by the decidua lining the fundus uteri, or decidua vera, was irregular and slightly reticulated. The inferior convex surface formed by the decidua covering the ovum, or decidua reflexa, was perfectly smooth, resembling the external serous surface of the uterus. Into this cavity the Fallopian tubes freely opened by palpable orifices; that on the left side by which the ovum had entered the uterus being rather more than a line in diameter, that in the right rather less. The cavity thus formed between the decidua lining the fundus uteri and the decidua covering the upper and unattached portion of the ovum was filled with a red-coloured serous fluid. The ovum was next laid open by an incision through the chorion parallel with the longitudinal incision of the uterus, and the amnion enclosing the embryo was brought into view. The placenta was situated prin¬ cipally over the cervix and posterior part of the body of the uterus, and the decidua closely adhering to the placenta passed across the upper part of the cervix uteri in the form of a thick reticular membrane. The decidua was then observed to extend upward between the uterus and chorion every where firmly connecting these together as high as the entrance of the Fal¬ lopian tubes. From this point the deciduous mem¬ brane was spread out in two different directions, viz. over the upper convex and unattached surface of the ovum, and over the whole concave surface of the fun¬ dus uteri, so as to form the cavity above described
