12. Polar spindles, polar body formation and fragmentation 

 (abnormal cleavage?) occurs particularly in the atresia folliculi 

 preceding sexual maturity. 



13. The Graafian follicles of the adult period are of a somewhat 

 different type as compared with those of the growth period (pre- 

 sexual). Intergradation is, however, obvious. 



BIBLIOGRAPHY 



An extensive list of literature references is not given. The ovary of the cat 

 has been a favorite object of investigation: Pfliiger ('63), His ('65), Rouget ('79), 

 Schulin ('81), Janosik ('85, '88), Giacomini ('87), Coert ('90), H. Rabl ('98), Ganfini 

 ('07), Sainmont ('05), von Winiwarter and Sainmont ('08), have considered its 

 structure and development. The last named, however, have so fully considered 

 the literature upon the development of the mammalian ovary and that of the 

 cat in particular, that a repetition here would be quite unnecessary. Only the 

 titles of papers upon the mammalian ovary, referred to in the foregoing brief dis- 

 cussion, are therefore here included.
