Plate 7.

Fig. 7. Tangential Section through the Blastocyst Wall, showing cyto-trophoblast and plaHniodi-trophoblast. x 320 D. pl., plasinodium ; nuc., cell with large single nucleus ; nucr^ cell with two nuclei.

The cellular layer shows great irregularity in the size of the nuclei ; many cells show two, othei's three, some multiple nuclei.

Fig. 8. Section of the Amnio-Embryonic Vesicle, x 320 d.

The drawing repi-esents the walls of the vesicle restoi-ed by the superposition of three successive sections. The mesoblast is slightly indicated, and the vesicle is seen to be attached more closely and firmly at one point.

Fig. 9. Section of the Entodermic Vesicle, x 320 d.

Some of the surrounding mesoblast cells and thi-eads are represented.
