 body. The course of the nerves of the extremities 

 in general, strongly resembles their distribution in

 of that extremity, lie much more superficial, pass 

 over the head of the femur in immediate contact 

 with the capsular ligament. 



The Heart, Lungs, and Principal 

 Bloodvessels. 



The size and position of the heart and lungs pre- 

 sent nothing peculiar. The apex of the heart is to-

 and the baboon, is attached to the diaphragm. The 

 left lobe of the lungs had been inflamed, and sunk 

 in water. There are three lobes in the right lung, 

 and two in the left, as in man. The course of the
