FIG. 12. A detailed drawing of vesicle no. 10 as seen from the ventral side as a 

 semi-transparent object. The embryos in white (I and IV) are on the upper side 

 of the vesicle, and since there is an inversion of germ layers, these are seen from 

 their ventral aspects. Embryos II and III are shaded, and lie on the far side of the 

 vesicle. For a fuller description see text. X 9.
