 a small part, H, by the Lungs, L L, on each side, upon which the outline of 

 the removed ribs is shown by the dotted lines. D, Diaphragm, arching 

 quite across the body, as shown in Fig. 60. L, Liver, S, Stomach, nearly 

 empty, c c c, colon, III. small Intestines. The ribs are cut farther back 

 above than below the diaphragm. 



Fig. 55 is like Fig. 54, except that the ribs of the chest are cut still 

 farther back, and the lungs made to recede and expose the Heart and large 

 vessels more to view. 



These beautiful cuts are taken from Bennett's magnificent work on 

 practical medicine, being copied by him from the excellent work of Sibson. 

 They truly represent the position of the organs.
