LESSON XXXII. 

 TISSUES OF REPRODUCTION. 



A. OVAEY. 



1. Take an ovary of a mammal, e.g. cat, hardened 

 in a mixture of equal parts of chromic acid "3 p.c. 

 and 60 p.c. alcohol, and prepare longitudinal 

 sections passing through the hilus. 

 Observe first with a low and then with a high 

 power 



a. The germinal epithelium, consisting of a 

 single layer of short columnar cells covering 

 the surface of the ovary except at the hilus. 



h. The connective tissue radiating from the 

 hilus throughout the ovary to form the 

 stroma; in this many blood vessels are 

 seen; towards the periphery the fibrous 

 tissue largely disappears (cp. § 2. a); immedi- 

 ately underneath the epithelium the stroma 

 forms a denser layer, the tunica albuginea. 



c. Small Graafian follicles forming a zone 

 a short distance below the germinal epi- 

 theUum.
