EXPLANATION OF PLATES. 

 Plate vi. 



Fig. 1. — Section of ovary (C) showing earliest stages of ovum ( x 350). 



Above and to the left is seen the surface epithelium of the ovary, and in 

 the right hand corner below appears a portion of an early corpus luteum. 

 Five young ova are seen in the ovarian stroma. Bound them all, cells are 

 arranged more or less regularly. These are the early representatives of the 

 membrana granulosa. The two smallest ova show no vitelline membrane; 

 the other three do. All the young ova show the granular character of the 

 cytoplasm, two show nuclei, and one a definite nucleolus in the nucleus. 

 Round the largest of the five ova, the membrana granulosa is seen to be two 

 cells thick in the lower and left half, whilst above and to the right there 

 appears a rudimentary basal membrane. The rudiments of a theca are also 

 seen outside the lower half of the membrana granulosa of this largest ovum. 



Fig. 2. — Section of ovary (C) showing stages subsequent to those shown in 

 fig. 1 ( X 75). 



Ova of various sizes are shown, and the multiplication of the layers of the 

 membrana granulosa is seen. Below in the right hand corner is a large ovum
