Dreyer's demonstration that splanchnic stimulation increased the content of epinephrin in blood from the adrenal veins has been confirmed by several observers. Adrenal secretion therefore is under control of the sympathetic system. Major emotional disturbances indicate the dominance of sympathetic impulses.

Do not the adrenal glands share in this wide-spread subjugation of the viscera to sympathetic control? To try this suggestion the inhibition of contraction in strips of longitudinal intestinal muscle, sensitive to epinephrin 1 to 20,000,000, was used as a biologic test.
