In the present case it is worth while to reflect that oftentimes men who awaken from a long-cherished though pious error betray their kinship to the beasts; while truth, sedulously handed down from generation to generation, and advancing enlightenment, make men more human.

Would that we could diffuse abroad a conception of the full truth of the Darwinian doctrine of development, to the end that every thinking man who has not already been caught by the counter-current might know what it comprises and what consequences it does not warrant!


THE readers of the "Monthly" will remember the account of "An Infant's Progress in Language," by F. Pollock, in our September number. We also published an article on "Lingual Development in Babyhood," by M. Taine, in June, 1876. M. Bernard Perez has just published a book upon an analogous subject—the mental development of children under three years of age. The following résumé of his observations is translated from the "Revue Scientifique" for November, 1878.

Vision.—Color attracts a babe; lively colors charm it, dull colors also please if they are positive and distinct. Two children, one three months, the other five, were delighted by some sketches of a grayish color.

Hearing.—One child a month old liked to listen to playing and
