As will be seen from Table III, so far as the cranial measurements are 
concerned the coefficients of variation in the albino rat are slightly less 
than in man, though the difference is by no means large. It is interesting 
to note that the magnitude of variability both in man and rat is in the 
same order for corresponding characters, that is the variability of the 
cranial capacity is considerably greater than the remaining three linear 
measurements both in man and rat. This is perhaps due to the fact that 
the cranial capacity is itself highly variable and in addition the technical 
difficulties of determination of the capacity influence the results further. 
Pearson, 97, o1, with reference to variation in the several dimensions 
of the human skull, thinks that with advance in civilization woman 
tends to gain in variability on man (see on Aino and Naquada races). 
Nevertheless, if we examine the data recently obtained by Fawcett, 02,
