We are dealing, in these experiments, less with the effects 

 of section of intestinal nervous supply on the local vascular 

 walls than with those of impaired suprarenal functions, the 

 connection between the adrenals and the anterior pituitary on 

 one side being removed. Decrease in the suprarenal substance 

 supplied to the blood, and therefore of oxidizing substance in 

 the plasma, was the main morbid factor. The functional en- 

 ergy of the intestinal crypts, glands, and follicles being im-
