[Note. The application of the theory of frequency curves to rates as distinguished from 
total frequencies is possibly open to criticisms, which might touch also the applicability of the 
X 2 test for goodness of fit. That test essentially concerns total numbers dealt with, and is not 
necessarily a test of good graduation formulae. The groups given by Dr Maynard, however, 
seem of much interest and suggestiveness. Editor.]
