The results recorded show that in the frog a sudden rise of the intraventricular pressure above the normal produced by clamping the aortæ causes a temporary decrease in the rate of the heart if the peripheral neurones of the heart are not interfered with; but that an acceleration is produced when these neurones are thrown out of action by the application of atropine. The observations seem to indicate that these neurones play a part in regulating cardiac action.
