PLATE II. 



EXPLANATION' OF FIGURES. 



4. Follicle-cells and a part of the cytosome of the C-egg, fixed by Da Fano's 

 modification of Cajal's method for Golgi apparatus, and stained with Nile blue 

 sulfate. Longitudinal section 4 micra in thickness; cells 1.5 micra in length. 

 Drawn with camera lucicla. 



5. Follicle-cells of the ZJ-egg, fixed by Kopsch's osmic acid impregnation method; 

 unstained. Longitudinal section 3 micra in thickness; cells 3.5 micra in length. 

 Drawn with camera lucida. Lighter granules in the cytoplasm are of the same 

 character as the black ones, but lie at a lower level. 



6. Follicle-cells of the B-egg, fixed by Champy's method, and stained with 

 Dclafield's haemotoxylin. Longitudinal section 3 micra in thickness; cells 3.5 

 micra in length. Drawn with camera lucida. The nucleus tends to lie in the 

 proximal region of the cell, while the distal region is occupied by a large number 

 (jf granules. 



Symbols. 



d.g., distal droplet, j.g., fuchsinophile granules, i.g., intermediate globules. 

 l.g., large type of globule, n.s., nuclear strand.
