The blood pressure measured directly in the distal part of the central ear artery is dependent upon the degree of vasodilation of the vessel, and exhibits spontaneous variation. This variation is abolished by hexamethonium in doses which had only a minor, transient hypotensive effect. While the degree of ganglionic block could not easily be quantitated, stability of peripheral arterial pressure and heart rate persisted for more than 2 hours.
