phragmatic and renal surfaces of the spleen. From the spleen, 

 the two layers are continued backwards to the anterior surface 

 of the left kidney, where they finally diverge from one another. 

 It will be seen that the omental bursa, which lies behind the 

 stomach, is bounded on the left side by the gastro-splenic 

 ligament, the hilus of the spleen and the lieno-renal ligament. 

 If a section is made through the abdomen immediately 

 below the epiploic foramen (Fig. 89, B), the omental bursa

of the epiploic foramen (of Winslow). 

 The section cuts the stomach along the line B in Fig. 89. 



is seen as a completely closed sac. The peritoneum on the 

 posterior surface of the stomach (Fig. 91) covers the posterior 

 aspect of the pylorus and is continued for a short distance 

 over the posterior surface of the first part of the duodenum. 

 It then becomes reflected on to the posterior abdominal wall, 

 and this reflection forms the upper part of the right lateral 

 boundary of the omental bursa. When Figs. 90 and 91 are 

 compared with one another, it will be found that the two layers 

 of peritoneum which separate the inferior vena cava from the
