Fig. 7. A mid-cross section of an ovum 8 to 9 days of age

Note that the amniotic cavity is no more advanced than is that of the younger specimen seen in ii . 6, although there are several amniogenic cells arising from the adjacent trophoblast in the ol er specimen. Likewise, mesoblastic formation is more advanced, as shown by the presence of an early exocoelomic membrane. In places the mesoblastic cells of the latter are still attached to the trophoblast from which they appear to be originating. Carnegie 8171, section 3-2-12, X 300.
