PLATE IX 



FIG. 123. 



Drawing of radiograph of a normal stomach in the vertical 

 position after an ordinary bismuth meal without the contractions 

 seen in the preceding plate. 



The lighter shadow is a composite drawing taken at varying 

 periods after the meal, showing the appearance of the lowest 

 part of the ileum, the caecum, and large intestine as the bismuth 

 was passing through. 



The tracings were made orthodiagraphically, and are there- 

 fore to scale and not distorted. Drawing by A. F. Hertz, 

 M.D., F.R.C.P.
