Plate 2

Fig. 2. Photograph ( x 12) of the surface view of the implantation site of the Barnes embryo. The implantation site itself appears as a slightly elevated area of the endometrium on which openings of the uterine glands can be seen. The surface of the endometrium shows characteristic shallow and irregular furrows.

Fig. 3. Photograph ( x 3-5) of the surface view of the partially opened implantation site from which a 28-somite embryo (Camb. H. 710) had been removed. Chorionic villi are seen on the everted cut surface of the decidua capsularis. Photomicrographs of sections through this implantation site are illustrated in Pl. 5, fig. 14 and PI. 7, figs. 20-22.

Fig. 4. Photograph ( x 1-1) of ageneral view of the interior of the uterus containing the implantation site of a 10 mm. embryo (CX. 100). A small opening has been made through the central part of the decidua capsularis. Note the smoothness of this portion of the decidua in comparison with the furrowed decidua vera (parietalis).

Fig. 5. Photograph ( x 3-5) of the implantation site of a 10 mm. embryo (CX. 100) with the decidua capsularis removed to an extent sufficient to show the embryo, within the collapsed amnion, and the yolk sac. Note the extent of development of the chorionic villi related to the decidua capsularis. This photograph has been rotated in relation to fig. 4 to show the embryo in a suitable orientation. A section through the placenta of this specimen is illustrated in Pl. 8, fig. 23.
