THE REPRODUCTIVE ORGANS. 



BEFORE describing the method of Reproduction or the way in which 

 the species is propagated, it will be advisable to describe the structure 

 of those organs which in either sex are concerned in reproduction, and 



FIG. 424. Diagrammatic view of the uterus and its appendages, as seen from behind. The 

 uterus and the upper part of the vaerina have been laid open by removing the posterior wall: the 

 Fallopian tube, round ligament, and ovarian ligament have been cut short, and the broad ligament 

 removed on the left side; u, the upper part of the uterus; c, the cervix opposite the os internum; 

 the triangular shape of the uterine cavity is shown, and the dilatation of the cervical cavity with 

 the rug termed arbor vitee; v, upper part of the vagina; od, Fallopian tube or oviduct; the nar- 

 row communication of its cavity with that of the cornu of the uterus on each size is seen: I, round 

 ligament; lo, ligament of the ovary; o, ovary; i, wide outer part of the right Fallopian tube: fi, its 

 fimbriated extremity; po. parovarium; ft, one of the hydatids frequently found connected with the 

 broad ligament. %. (Allen Thomson.') 



which are called the genital or generative organs or the sexual appa- 

 ratus. 



A. The Genital Organs of the Female. 



The female organs of generation (Fig. 424) consist of two Ovaries, 

 whose function is the formation of ova; of a Fallopian tube, or oviduct, 

 connected with each ovary, for the purpose of conducting the ovum from 

 the ovary to the Uterus or cavity in which, if impregnated, it is retained 

 until the embryo is fully developed, and fitted to maintain its existence 

 independently of internal connection with the parent; and, lastly, of a 

 canal, or vagina, with its appendages, for the reception of the male or-
