in consequence of the local thickening of .the circular fibres of the muscular coat, but 

 also in part on account of the increased thickness of the mucosa itself, which in this 

 part of the stomach may measure over 2 mm. At the cardia it is thinnest, .5 mm. 

 or less, while in the intermediate region it is about i mm. The increased thick- 

 ness at the pyloric end is due to the considerable depth of the depressions, or
