The decidua is torn, and turned somewhat aside, to shew the smooth and opake decidua reflexa. AA _ The rough, external surface of the decidua, which exfoliated from the womb. B The outside of a small portion of the placenta, the rest of which was situated on the back-part of this object. CCCCC The internal cribriform surface of the decidua, which, in the first months of pregnancy, does not adhere to the membranes which it encloses. DDDD The lacerated edge of the decidua, which had been continued into the edge EEE of the same membrane. 1 F The decidua reflexa spread over the outside of the chorion. GG — The angle of reflection at the edge of the placenta, where the inner layer of the decidua is turned over the chorion ; much in the same manner as the inner lamella of the pericardium is reflected, to cover the outer surface of the heart. H The termination of the decidua at the cervix uteri. PIU Ir A vertical section of the same. AAA The section of the placenta; which, we must suppose, had adhered to the up- per and back-part of the womb. BB The section of the anterior portion of the decidua. CC The section of the posterior portion of the decidua. D 'The termination of the decidua at the cervix uteri. EE The cavity of the amnion, in which the embryo hangs by a slender navel-string, from the inside of the placenta. F The section of the three membranes, which are not only contiguous, but adhere to one another, viz. the amnion, the chorion, and the decidua reflexa. GG The angle, at the edge of the placenta, where the inner layer of the decidua is reflected over the outside of the chorion. H Here those three membranes are a little separated, to shew their course at the placenta. FIG. II. An abortion of about eight weeks. A small strap of the decidua is cut out, and turned up, to shew the cavity between it and the other membranes. A . The cut slip of the decidua, B The part of the conception where there is no decidua, viz. opposite to the pas- sage through the cervix uteri. CCC . The external surface of the decidua. D The decidua reflexa covering the chorion and amnion, which project and fill up the cavity of the decidua. X F The outside of the upper part of the placenta. FIG. IV. The same, when the decidua had been opened by a crucial incision, and the ‘ four angles had been turned off, and then a round piece of the decidua reflexa dissected off, and turned to one side, to shew the loose vessels on the outside of the chorion. A,B. See Fig. III. CCCC The inside of the four angles or flaps into which the decidua was reduced by a crucial incision. DDJD The decidua reflexa, covering the other membranes. EE 'The angle, at the edge of the placenta where the interior lamella of the decidua is continued over the outside of the chorion, forming the decidua reflexa. F . Around portion of the decidua reflexa dissected from the outside of the chorion and turned aside. G The chorion, with its shaggy vessels, laid bare. These vessels adhered firmly to the decidua reflexa, and parts of them were cut off with that membrane. Els «Vs An abortion of the same age, consisting of the chorion only, with its vessels and contents ; that is, without the decidua, or uterine part of the secundines. AAA The larger and more crouded branches of the shaggy vessels which shoot from the external surface of one part of the chorion, to mix with the decidua, or uterine part, to form the placenta. BB That portion of the chorion which afterwards becomes the uniform transparent membrane. It is covered with fewer and more delicate floating vessels, which lose themselves in the decidua reflexa. The embryo is seen through it. Cc The vesicula umbilicalis on the outside of the amnion, seen through the chorion; with a whitish thread (the remains of an artery and vein) leading from it, towards the navel of the embryo. ELG VL The same opened. The membranes, which were at the fore-part, being cut from the placenta, and turned up, the embryo is distinctly seen. A The vesicula umbilicalis, from which B, the remains of an artery and vein, in the form of a white thread, pass to C, the navel of the embryo, with some turns of the intestines lodged in the beginning of the navel-string.
