Figure 9. A portion of the same ovary highly magnified showing the gradual change of peritoneal 
epithelial corpuscles (7) on the peduncle into germ epithelial corpuscles (h) at the 
lower border of the ovary (c). (Page 359.) 
Figures 10,11, 12. Surface view of the germ epithelium from the same ovary. In figure 12, among 
the ordinary germ epithelial corpuscles (h) large spherical germ epithelial corpuscles (2) 
are seen. (Page 358.) 
Figure 13. The ordinary germ epithelial corpuscle (h) and the larger spherical corpuscle ((). 
(Page 358.) 
Figures 14, 15, 16. Profile views of the germ epithelium. Among the ordinary columnar corpuscles 
(h) large spherical corpuscles (2) and primordial ova (m) are seen. Fusiform cor- 
puscles (m) are in contact with the yelk of the primordial ova. (Page 358.) 
Figure 17, A large primordial ovum (m), with several large spherical corpuscles (/) included in a mesh 
of the stroma (j) under the germ epithelium (h).

stroma (j), under the germ epithelium (h).

Figure 19. A portion of the ovary of a human fcetus of 3} months, showing the germ epithelium (h) 
and groups of large germ epithelial corpuscles or egg clusters (0) imbedded in the stroma. 
The stroma (/) consists almost entirely of connective-tissue corpuscles. (Page 361.) 
Figure 20. A portion of the same ovary, showing large primordial ova (m) imbedded in the stroma (/). 
Fusiform corpuscles (7) of the stroma are seen in contact with the yelk of these primor- 
dial ova. (Page 361.) 
Figure 21. A portion of the ovary of a human foetus of 74 months, showing the manner of inclusion 
of the germ epithelial corpuscles in groups (q) in the stroma of the ovary. (Page 362.) 
Figure 22. A portion of the ovary of a human fcetus of 74 months, showing in section the furrows 
(p) which lie between the prominences on the surface of the ovary. (Page 363.) 
Figure 23. A portion of the ovary of a child at birth, showing the stroma (j) crowded with primor- 
dial ova (m). 
PLATE XXX. 
Figure 24. Section through the ovary of a human foetus of 74 months, showing the germ epithelium 
(h), large spherical corpuscles (2), and groups of similar corpuscles or egg clusters (0) im- 
bedded in meshes of the stroma (j). In the lower part of the figure many primordial 
ova (m) in various stages of development are seen. In contact with each primordial 
ovum are fusiform, connective-tissue corpuscles (m), similar to the fusiform corpuscles of 
which the stroma consists. Numerous blood-vessels (&), whose walls consist of con- 
nective-tissue corpuscles, ramify throughout the whole ovary. (Page 365.) 
Figure 25. A small egg cluster consisting of large spherical germ epithelial corpuscles with fusiform 
connective tissue corpuscles (m) intermingled. (Page 366.) 
Figure 26. A small group of spherical germ epithelial corpuscles. 
Figure 27. A primordial ovum. It has no zona pellucida. 
Figures 28, 29. Primordial ova (m). In contact with and indenting the yelk substance of each, are 
fusiform connective-tissue corpuscles from the wall of the young Graafian follicle.

is the ovarian stroma (j). From the human ovary at birth. 
Figure 31. The corpuscles of the membrana granulosa from the nearly ripe Graafian follicle of the 
rabbit’s ovary. The letter v points to the division of the nuclei of the corpuscles.

birth.

Figures, 33, 34, 35 36, 37, 38, illustrate the development of the membrana granulosa in the ovary of 
an adult rabbit. (Page 368.) 
Figure 33. A primordial ovum (m). Fusiform connective-tissue corpuscles (n) of the stroma (/) lie in 
contact with the yelk substance of the young ovum. 
Figure 34. A young ovum farther advanced in development than the last. Some of the fusiform cor- 
puscles (7) in contact with the yelk are swollen out.
