THE ADRENAL BODIES 



231 



What follows after adrenal suppression when a weak 

 stimulation causes a depressor response we have not ascer- 

 tained. 



If we investigate the difference between the intact and the 

 denervated limb in regard to their respective responses to 

 injection of small doses of adrenin (0'2c.c.tolc.c.ofal : 100, 000 

 solution) we must bear in mind the results obtained by Hoskins,

Gunning, and Berry. It was found that with nerves intact 

 adrenin causes active dilatation of the muscles and vaso- 

 constriction in the cutaneous vessels, so that while the entire 

 limb usually constricts, a skinned limb will invariably dilate. 

 This result we have been able to confirm. As further pointed 

 out by Gruber, the results just described are obtained only when 

 the nerves to the limb are intact. In the denervated limb, at
