The Stomach Bed. 



It has been already described how the stomach, resting on its 

 bed, is supported at its lower part on the gastric surface of the 

 pancreas, which, sloping downwards and forwards, terminates in 

 the more or less prominent anterior border and forms, in 

 varying degrees, a supporting shelf for the stomach. 



When the stomach is lowly situated it tends to press down the 

 anterior border of the pancreas, to increase the vertical depth of 

 its gastric surface, and to diminish the depth, antero-posteriorly, 

 of its inferior surface ; that is, to flatten out the pancreas. More- 

 over, this process is accompanied by a pushing down of the 

 pancreas over the face of the left kidney, thus giving an 

 increased gastric surface to the kidney. In its descent the 

 pancreas occasionally drags down the left supra-renal body with 

 it to some extent. Finally, the descent of the stomach is not 

 accompanied by a descent of the left kidney. 



The reverse of these processes takes place when the stomach 

 is raised up by distended intestines; the depth on a vertical 

 plane of the gastric surface of the pancreas is diminished, 

 its inferior surface is increased antero-posteriorly, its anterior 

 border becomes more prominent, and the gland, being pushed 

 upwards, tends to obliterate the gastric surface of the left 

 kidney. (See fig. 1, Plate LIV., Part II.) 



Fig. 7 is constructed to show these points graphically. 

 They will, however, be fully realised if the different Tables and 

 Plates be compared, especially by comparing Plates (XXI II., 

 XXIV.) of the duodenum and adjoining viscera on the reduced 

 scale with those of the similarly reduced outlines of the
