PLATE III. 

 (All drawings made approximately to scale.) 



7. Diagrammatic sketch of a follicle-cell of the 5-stage, unstained. The nucleus 

 lies in the proximal region of the cell, and a large number of refractive granules 

 occupy the distal region. 



8. Camera lucida sketch of a cell from the B-follicle, unstained. The nucleus 

 is in transition between the position in which its long axis is perpendicular to the 

 surface of the follicle and the position in which it is parallel to the surface. 



9. Diagrammatic sketch of a cell in the C-follicle, stained with janus green. 

 Green-staining granules are shown outlining the nucleus and lying in the proximal 

 region of the cytoplasm. 



10. Surface view of a similar cell under the same conditi' 



11. Camera lucida sketch of surface view of cells from the .-1 -follicle, stained 

 with neutral red and brilliant cresyl blue. The distal granules take the red stain. 



12. Camera lucida sketch of surface view of cells from the .B-follicle, stained 

 with neutral red. The distal granules are red. 



13. Camera lucida sketch of a cell from the ,4-follicle, unstained. The nucleus 

 occupies the proximal region of the cell, and a number of highly refractive granule-. 

 occupy the distal region. 



14. Camera lucida sketch of surface view of a cell from the A -follicle, stained 

 with methyl green. The distal granules are not stained. Some of them show 

 small lobular irregularities, as if they were being formed by the coalescence of 

 several smaller granules. 



15. Camera lucida sketch of a whole egg-string. The black outline surrounding 

 each egg represents the follicle. Beginning with the ripest in the series, the eggs 

 are lettered in the order of their maturity. The B-follicle is the thickest of the 

 series.
