GENERATION AND DEVELOPMENT. 



In the male, the Mullerian ducts have no special function, 

 and are but slightly developed : the small prostatic pouch, or 

 sinus pocularis, forms the atrophied remnant of the genital 

 cord, and is, of course, therefore, the homologue, in the male, 

 of the vagina and uterus in the female. 



FIG. 245. 



Urinary and generative organs of a human female embryo, measuring 3% inches 

 in length. A, general view of these parts ; 1, suprarenal capsules ; 2, kidneys ; 3, 

 ovary ; 4, Fallopian tuba ; 5, uterus ; 6, intestine ; 7, the bladder. B, Bladder and 

 generative organs of the same embryo viewed from the side ; a, the urinary bladder 

 (at the upper part is a portion of the urachus) ; 2, urethra ; 3, uterus (with two cor- 

 nua) ; 4, vagina ; 5, part as yet common to the vagina and urethra ; 6, common ori- 

 fice of the urinary and generative organs ; 7, the clitoris, c, Internal generative or- 

 gans of the same embryo ; 1, the uterus ; 2, the round ligaments ; 3, the Fallopian 

 tubes (formed by the Mullerian duets) ; 4, the ovaries ; 5, the remains of the Wolffian 

 bodies. r>, External generative organs of the same embryo ; 1, the labia majora ; 2 

 the nymphse ; 3, the clitoris. After Miiller. 



The external parts of generation are at first the same in 

 both sexes. The opening of the genito-urinary apparatus is, 

 in both sexes, bounded by two folds of skin, whilst in front of 

 it there is formed a penis-like body surmounted by a glans, 

 and cleft or furrowed along its under surface. The borders of
