Plate 28
Figs. 33 a, 33 6, 33 c—Blastocyst 38, sections 1/2, 16/1, and 2/2 (x 400). In fig. 33 a, which passes through the central region of the embryonal ecto- derm (e.ect.), the covering trophoblast has disappeared and a slight depression is present on the surface of the ectodermal mass, the cells of which are now assuming a columnar arrangement. The covering trophobla3t (c.tr.) is still present over the more peripheral portion of the embryonal ectoderm (figs. 33 6 and 33 c).
Fig. 34.—Blastocyst 42. Section 7/2 ( x 420). sh.ect., shield-ectoderm.
