A. "Nest" of small ova (s. c), each about 1 M in diameter, one larger ovum (/.o.) 



50 f in diameter. Whole nest contained within special arrangement of stromal 

 cells {st. c.)- X about 300 diameters. 



B. Developing ovum (m. o.), surrounded by rapidly atrophying small ova \q.o.); 



I., lumen of ovisac; n., " germinative spot"; st., stroma. Diameter of large ovum, 

 120 /i. X 500 diameters. 



C. Cross-section of one horn of ovary. /., lumen of ovisac; o., ova; ov. s., ovisac; 



St., stroma. Guide line to st. crosses place of attachment of stroma to median wall 

 of horn of ovisac. X about 50 diameters. 



D. "Nest of yellow cells." Diameter of individual "yellow cells" (^. c.) about 15 Ms/, c, 



arrangement of stromal ceils around yellow cells, as around "nest" of small ova 

 (st. c, in fig. A.) X 200 diameters. 



E. Few "yellow cells" more highly magnified to show pigment-granules and general 



appearance of slow degeneration. Nuclei can not be distinguished in photo- 

 graph, though distinct enough in section. X about 800 diameters. 



F. 3 adjacent " nests " of ova (n.), each with developing ovum ; st. c , stromal cells which 



separate " nests " and likewise developing ova from one another. X 2 1 diameters.
