PLATE VI. 



FIG. ii. A section through an egg in about a four-cell condition showing the 

 most normal cleavage spindle (m.s) found in all the present material. Two other 

 cells show unmistakable resting nuclei (n l and w 2 ). ( X 800.) 



FIG. 12. An egg with many small nuclei in the formative protoplasm. Such a 

 condition may have arisen through the formation of a multipolar spindle like that 

 shown in Figs. 13 and 14. This is a very frequently found condition. (X 800).
