The statement that respiratory exchange in the lower branches of the bronchial tree, the bronchioles and the alveoli is carried on chiefly by diffusion, is probably correct up to a certain point. However, the importance of respiratory movements in the ventilation of the air sacs cannot be relegated to a rôle of minor importance. Without such movements the respiratory function fails to support life even under artificial conditions of enormously increased diffusion pressures. The efficiency of the ventilating system inaugurated by the respiratory movements is obviously most important in abnormal pulmonary conditions. On approaching the subject of pulmonary ventilation it
