increase in number of erythrocytes in these animals. If polycythaemia is due to some direct nervous influence it might be expected that in these animals in which the nervous condition is intact, nervous stimuli as fright, would cause an increase in number of red corpuscles. As the direct stimulation of the nerves to the liver causes no increase in number of erythrocytes, and as in animals in which epinephrin causes no polycythaemia nervous stimuli also cause no increase in number of red corpuscles, it appears probable that the polycythaemia following the stimulation of certain nerves is not due to a direct nervous influence, but to a reflex stimulation of the adrenals .and a secondary action of epinephrin on the liver.
