a,gain and run to tlie dorsal limb of the pylorus. One layer 

 passes thence on to the dorsal surface of the cardiac stomach, 

 and the other unites with the dorsal layer of the ventral sheet. 

 Between the serous covering of the cardiac stomach and the 

 layers passing between the two limbs of the pylorus there is a 

 peritoneal pocket (text-fig. 12, A, p). 



When the dorsal sheet is traced to the pyloric curvature it 

 separates into anterior and posterior layers. The former becomes 

 continuous with the part of the ventral sheet running between 

 the two pyloric limbs (text-fig. 12, 0,p), and the latter passes

round the bend and is reflected on to the right surface of the 

 cardiac stomach (text-fig. 12, 0, Cs). 



The posterior pole of the spleen is connected by a fold 

 of peritoneum to the ventral surface of the cardiac stomach, 

 encircling the ventral pyloric limb and curvature. It shuts in a 

 peritoneal pocket containing the ventral limb.
