out in this. Observe that they are pyriform bodies, 

 the apex being above (Fig. 47). 



Ascertain that each ovary consists of a large 

 number of follicular tubes, commencing as fine threads 

 and ending in the oviduct. Observe especially the 

 follicular tube forming the apex of the ovary, as here 

 this is most readily made out. 



Ascertain that each follicular tube contains 

 several egg follicles, the lowest of which is the most 

 advanced in development.
