EXPLANATION OF FIGURES 



26 Oocyte, 1.74 x 1.44 mm., cut approximately in the long and polar axes, but 

 much distorted in sectioning. The germinal vesicle is ])eripheral. The location of 

 the future latebra is indicated by the finer meshwork at the center of the oocyte. 

 Taken with a one-half inch B. and L. objective, X 40. p./;., peripheral protoplasm. 



27 Oocyte, 2.5mm. in long axis (life), X 40, Leitz obj. no. 2. Cut in polar axis, 

 pcriiendicular to the long axis and compressed from right to left in cutting. The 

 follicular epithelium has shrunken somewhat from the theca folliculi, and there is 

 a shrinkage tear near the germinal vesicle. The region of the latebra (lat.) is 

 clearly defined at the center and the layers of yolk granules indicate the rhythmical 

 formation of yolk. The stigma is shown in cross section at st.
