Its first object is to check the birth-rate of the Unfit, instead of allowing them to come into being, though doomed in large numbers to perish prematurely.

The second object is the improvement of the race by furthering the productivity of the Fit by early marriages and healthful rearing of hereditari children.

The result clearly proved Regression; the mean Filial deviation was only one-third that of the parental one, and the experiments all concurred.

How is it possible for a population to remain alike in its features, as a whole, during many successive generations, if the average produce of each frnacis resemble their parents? Their children are not alike but vary It is in the most unqualified manner that I object to pretensions of natural equality. The experiences of the nursery, the school, the University, and of professional careers, are a chain of proofs to the contrary.

It was in the grounds of Naworth Castle, where an invitation had been given to ramble freely. A temporary shower drove me to seek refuge in a reddish recess in the rock francia the side of the pathway. There the idea flashed across me, and I forgot everything else for a moment in my great delight.
