1. My own observations 



a. The changes of the interstitial cells (figs. 84- to 91). The one 

 shown in figure 84 is an interstitial cell in normal condition, 

 it is very small and ball-shaped, and the cell body as com- 

 pared with its nucleus exceedingly small, containing within a 

 certain quantity of plastosomes which are largely rod-shaped.

The nucleus is extremely clear and contains a nuclear network 

 and conspicuous nucleoh. Figure 85 is remarkably larger than 

 the former and is oval. The protoplasm increases in quantity 

 and so does the nucleus. Within the cell body there are no 

 plastosomes to be found, but, on the contrary, there are, in 

 large numbers, strongly black-stained and almost equally shaped 

 lipoid granules. The cell illustrated by figure 86 is filled by 

 large numbers of vacuoles within the cell body, and very little 

 is protoplasm proper. The plastosomes, being rod-shaped, for
