448 J. MCA. KATER. 



PLATE II. 



FIG. 14. Early bud. Extremely large vacuole. 



FIG. 15. Metachromatic granules entering the bud. Nucleus not yet beginning 

 division. 



FIG. 16. Early prophase. The chromatin is collecting on the linin strands. 

 A few metachromatic granules visible in both cells. 



FIG. 17. The nucleus is breaking up into chromosomes. Slightly oblique view 

 making bud appear abnormally small. 



FIG. 18. Metaphase. The chromosomes are separating on the equator of the 

 spindle. 



FIG. 19. Anaphase. Centrosome and spindle very evident. Metachromatic 

 granules in both cells. 



FIG. 20. The same. Slightly later. 



FIG. 21. The chromosomes are passing through the isthmus. A few meta- 

 chromatic granules in opposite ends of both bud and parent cell. These are much 

 smaller than the chromosomes. 



FIG. 22. Late anaphase. Spindle very evident. A second bud on the parent 

 cell. 



FIG. 23. The spindle not visible. The isthmus is closing. Chromosomes 

 collected near one point. 



FIG. 24. The cytoplasm has divided, the cells being held together by their 

 walls. Chromosomes beginning the apparent fusion. 



FIG. 25. Late telophase. Large nucleolus. Note bulges in nuclear membrane 

 between linin strands.
