" indifferent " anlagen. Hertwig. , 



Fig. 380. — Diagram of the development of the female genital organs from the 

 "indifferent" anlagen. Hertwig. 

 These diagrams should be compared with Fig. 378. The dotted lines represent the organs in the 

 relative positions they occupy in the adult (with the exception of the Mullerian duct in the 

 male and the mesonephric duct in the female, which ducts disappear for the most part).
