As we ascend from the more prolific inferior races to the Qua- 

 drumana and the Human species, the proportionate size of the body 

 of the uterus becomes materially increased, and that of the cornua 

 diminishes in the same ratio, until in the Monkeys and in Woman 

 the latter become quite "lost, and the now pyriform central part 

 appears to compose the entire' viscus, into the cavity of which the 

 Fallopian tubes seem immediately to discharge themselves. Thus 

 gradually, therefore, does the oviparous sexual apparatus assume the 

 viviparous type ; and then, passing through numerous intermediate 

 forms, ultimately attains its most concentrated condition in the 

 uterus of the human female. 



(857.) In every other part of the generative system we shall 

 likewise find the characters of the type at length completely estab- 

 lished. The ovaria (Jig. 335, a) entirely lose all traces of their 

 original racemose condition, for now the quantity of granular matter 

 enclosed along with the germ in each Graafian vesicle, the last rein-

 ovarian ovules are enclosed in a dense parenchymatous substance
