coni vasculosi, and globus major of the epididymis ; and thus a 

 direct connection between the secreting part of the testicle and 

 its duct is brought about. The Wolffian ducts persist in the 

 male, and are developed to form the body and globus minor of the 

 epididymis, the vas deferens, and ejaculatory duct on each side ; 

 the vesiculse seminales form diverticula from their lower part. 

 In the female a small relic of the Wolffian body persists as the 

 parovarium, a functionless collection of tubules lined with ciliated 

 epithelium near the ovary (see p. 798, fig. 610, po) ; in the male 

 a similar relic is termed the organ of Giraldes. The lower end 

 of the Wolffian duct remains in the female as the duct of 



Fig. 680. Diagram of two-horned uterus. The body of the uterus (in is formed by the 

 fusion of the two Mullerian ducts, the ununited portions of which form the oviducts,

Gaertner, which descends towards, and is lost upon, the anterior 

 wall of the vagina. 



The Fallopian tubes, the uterus, and the vagina are developed 

 from the Mullerian ducts. The two Mullerian ducts are united 

 below into a single cord, called the genital cord, and from this 

 are developed the vagina, as well as the cervix and the lower 

 portion of the body of the uterus ; while the ununited portion of 

 the duct on each side forms the upper part of the uterus, and the 

 Fallopian tube. In certain cases of arrested or abnormal 

 development, these portions of the Mullerian ducts may not 

 become fused together at their lower extremities, and there is left 

 a cleft or horned condition of the upper part of the uterus re- 

 sembling a condition which is permanent in certain of the lower 

 animals (see fig. 680).
