sex) is also 0.78. Considering the grandparents, the average coefficient 
of association between sons and father’s father, and daughters and the 
mother’s mother (no change of sex) is 0.67, while that between sons 
and the mother’s father, and daughters and the father’s mother (two 
changes of sex) is 0.74. This result agrees with that of Blanchard 
(1903) concerning the coat-color of horses and is not in harmony with 
Pearson’s (1900) and the writer’s (1903) concerning the eye-color in man.
