THE FEMALE ORGANS OF GENERATION. 249 



from the uterus, but much larger at their free extremities ; 

 being there somewhat after the resemblance of the end of 

 a French horn, which they still further resemble from being 

 convoluted. The horn-like extremity is furnished with a- 

 fringe called the morsus diaboli, one portion of which is 

 attached to the ovaries, the rest being free. The other 

 pieces of this fringe are in violent motion during the act, 

 and therefore catch the ovum as it falls from the ovaries, 

 and convey it to the tubes. The internal lining membrane 

 of the tubes is continuous with the mucous membrane of 

 the uterus, and is thrown into longitudinal folds, wdiich 

 suggests it is liable to distention. The next coat of the 

 tubes is continuous with the muscular coat of the uterus, 

 which invites inquiry as to why a muscle was placed into this 

 position if not to force something downward ? They are 

 situated within the folds of peritoneum which form the 

 broad ligaments of the uterus, and wherefore we are prompted 

 to ask is the outer investiture elastic, if not to permit the 

 passage of some substance ? The opening of the free end 

 of the Fallopian tubes into the cavity of the abdomen, is the 

 only known instance of a mucous membrane leading into a 

 serous sac. 



The ovaries, like the testes, have three coats ; an outer 

 one of peritoneum ; a middle one of white fibrous tissue ; and 

 an internal one which is vascular. They also somewhat 

 resemble the testes in shape, but here all similitude ceases. 

 Their interior is cellular. Within the cells are numerous 

 seeds of future eggs, which as they approach the surface 

 become matured ; and when the act is being performed burst 

 the coats of the ovary, and are carried down the Fallopian 

 tubes. Wherever an ovum has escaped a corpus luteum 

 is established, wdiich consists of a yellow spongy mass, 

 filling an empty space where once existed the ovum. The 

 arteries of the female parts lately described are those named 

 the spermatic, the uterine, the pudic, and the bulb. The 

 veins are the pudendal, the spermatic, and the uterine. 



The nerves are derived from the lumbar and the sacral 

 plexuses. 



Tlie mammary gland. — This is placed in front of, and 

 inclining to between, the hind legs. It consists of two 

 quarters in the mare, each of which are composed of a bag
