Henderson, Eyster and Bazett were published last week.]Since Corrigan in 1832 first described the typical pulse of aortic insufficiency and attributed its rapid collapse to diastolic backflow, clinical and laboratory investigators alike have attempted to evaluate the magnitude of the regurgitation in this condition. I have long maintained that crucial evidence of a considerable regurgitation has not been adduced and further that all the typical signs can be logically explained on the assumption that only a reasonably small regurgitation takes place. By this I mean a regurgitation volume equivalent to about 5 or 10 per cent of the systolic ejection, in contrast to the 50 or 60 per cent generally assumed by those who speak of a large, a considerable, a substantial or
