FIG. 23. X l>ooo. Telophase. Nucleus just forming. Showing the slowness 

 of the forming of the cell-wall in some instances. Compare with Fig. 22. 



FIG. 24. X ijOOO. Late telophase. Nuclear membrane formed. Chromosomes 

 become diffused. Cell " A " shows accessory chromosome, which is absent in " B." 



FIG. 25. X I ,OOO. Telophase of second spermatocyte. Each chromosome is
