less of a single mass, but here it may often be seen scattered 

 throughout the cell in little clumps. These often seem to melt 

 together, as it were, and form deeply staining liquid-like masses. 

 The nuclei in many of the eggs were shrunken, and showed 

 an irregular wavy border. This was true of the larger eggs 

 almost without exception. Fig. 5 shows a common form. The 

 nuclear material is collected into a granular mass in the center. 

 Irregular rods and granules of chromatin material can be dis-

tinguished. The nuclear membrane is collapsed and shrunken, 

 and surrounded by a lighter area of cytoplasm, which has the 

 appearance of streaming or being drawn toward the nucleus. 

 This aspect is due probably to the contraction of the nucleus, 

 which carries in the surrounding cytoplasm as it recedes. In 

 other cases the nuclei seemed to be in the last stages of degen- 

 eration, and were simply clear areas crossed by colorless feathery 

 strands (Fig. 8). 



Nucleoli might or might not be present. In the normal ^^^
