In a recent Shattuck Lecture Dock1 states that more progress has been made in the past thirty years in the quantitative study of the circulation of viscera than had been achieved in the previous three centuries. He predicts that the introduction of the vascular catheter and the use of radioactive isotopes will open a vast program of study of the circulation in various organs of normal and diseased men. While much of this advance was made possible by new technical methods, some of the data have been obtained by the injection or perfusion of organs post mortem by a technic that was possible even in the days of Harvey. A description of the circulation of an organ to be complete must include an estimate of oxygen needs, basal and maximal, the capacity of the vascular bed and the volume flow under varying conditions. The rates of flow during life
