This study was undertaken in order (1) to gain evidence for the transmission of the heart sounds in the arteries; (2) to secure evidence of the cause of the sounds heard in the brachial artery in taking blood pressure; (3) to determine whether or not any relation exists between arterial sounds and blood pressure, or between arterial sounds and arteriosclerosis, and (4) to determine whether or not arterial sounds have clinical and diagnostic value. Two hundred cases have been taken in regular order, some being persons in good health, some private patients, and some ward patients. In each case the name, age, sex, and diagnosis were recorded; then the pulse rate, and systolic, diastolic and pulse pressure were registered; the condition of the arteries was classified as normal or arteriosclerotic, and the heart sounds were classified as clear, split or murmurs. The stethoscope was applied without pressure over the right
