When compared with the normal condition (Fig. 9) it is evident that 

 the stomach and intestines are all greatly distended. The pancreas 

 (P) is seen in cross section, and the inferior surface, instead of being 

 obliterated, is actually increased in size, the pancreas being ap- 

 parently flattened from above downward, and extending shelf-like for- 

 ward between the distended stomach above and the distended small 

 intestines below. We have, therefore, wide superior and inferior sur- 

 faces, and a narrower posterior surface.

In order to eliminate the effect of the intestinal distension, and 

 to determine the effect of the distension of the stomach alone, the 

 experiment was varied in the next two foetuses as follows: First, an
