AND ABDOMINAL VISCERA. 25 



From these points the muscular substance passes 

 up along the walls of the thorax for some distance, and 

 then bends inward somewhat abruptly to end in the 

 central tendon. 



E. FEMALE REPRODUCTIVE ORGANS. 



If dissected upon a new dog, open the abdomen as in 

 the dissection of the abdominal viscera, and rem.ove the 

 stomach, intestines and liver. Then czd through the 

 skin and muscles above the pubis symphysis so as to ex- 

 pose this and the I'ami running from it above and 

 below for a short distance. Cut through the sym- 

 physis with bone forceps, and the rami above and 

 below the obturator foramen at a distance of about 

 one-half inch on each side of the symphysis. Remove 

 carefully the pieces of bo7ic thus isolated. 



1. The Ovaries. A pair of oval bodies of a pale 

 color, lying posterior and dorsal to the kidneys, at the 

 termination of the oviducts. Each, in the small dogs, 

 is less than one one-half inch long, and is concealed 

 in a membranous capsule, which must be cut open to 

 fully expose the ovary. 



2. The Oviducts. Each consists of two parts : pos- 

 teriorly a thick-walled tube, which unites with its 

 fellow of the opposite side to form the body of 

 the uterus ; anteriorly a very small convoluted tube 

 lying close to the ovary — the Fallopian tube. The 

 oviduct is connected to the dorsal wall of the 

 abdomen throughout its whole length by a broad 

 fold of peritoneum, the broad ligament. 



a. The Fallopian Tube is very narrow and 

 slightly convoluted. It lies close to the ovary ; its 

 anterior end expands into a capsule surrounding the
