of the earlier paper. In Table I we have grouped the results obtained from such 
data; the figures relating to males have already been published, those dealing with 
females are based upon the manuscript records, and are given for the sake of com- 
parison. It will be noticed that in two cases the correlations for the female data

are slightly smaller, in one instance perhaps significantly smaller, than the male 
values, while the relative variabilities are in two cases higher among the females. 
It was to be anticipated, from the nature of the case, that the results just given 
would be only rough approximations to the desired values descriptive of a healthy 
"General Hospital Population." This anticipation has been confirmed by other 
work. Thus Pearson has shown that the form of frequency distribution indicated 
by the graph of " healthy" hearts would suggest arbitrary limitation at each end 
of the distribution, some small and many large hearts having been unjustifiably
