 The lateral boundary of each of the gutter-like recesses is the 

 side wall of the abdomen, formed superiorly by the diaphragm, 

 which separates the peritoneal gutter from the lower part 

 of the pleural sac, and inferiorly by the flat muscles of the 

 abdomen. The medial wall of the right gutter is formed by 

 the right kidney and the ascending colon (see Figs. 136

The dissector should pass his hand, from above down- 

 wards, along each lateral gutter of the great sac, and he will 

 find that it is divided by a transverse fold of the peritoneal 

 wall into an upper and a lower part, but the division occurs at 

 very different levels on the opposite sides. The fold which
