The differences are not significant as can be seen in the correlation coefficients*, 
except that boys with jet-black hair have decidedly less weight than other boys, 
but means based on 18 and 19 cases are of little value. 
It was thought that the combination of hair and eye colour might prove a 
better criterion of racial differences than either separately, but a much larger 
number of cases would be required to test the point. For this purpose we 
grouped red and fair hair (1 and 2) together and dark and jet black (4 and 5), 
and the mean for each group is given below.
