Galton chiefly studied the families to which men of intellectual ability belong, especially in his Hereditary Genius and English Men of Science; various kinds of pathological families have since been investigated by Karl Pearson and his co-workers (see the series of Biometrika); the pedigrees of the defective classes (especially the feeble-minded and epileptic) are now being accurately worked out, as by Godden, at Vineland, New Jersey, and Davenport, in New York (see e.g. Eugenics Review, April, 1911, and Journal of Nervous and Mental Disease, November, 1911).

In many undesigned and unforeseen ways these registers may be of immense value. They may even prove the means of overthrowing our
