PLATE V. 



FIGS. 9 and 10. Two sections through one egg. This seems to represent about 

 an eight-cell stage. There are two cells with resting nuclei (n 1 and 2 ) and three 

 cells with more or less perfect mitotic spindles (m.s l -m.s*>). Cytoids are scattered 

 among the blastomeres, giving the appearance of cell multiplicity. ( X 800.)
