Book Reviews 643 were, according to the records, of low order, as were the Negroes, since the more intelligent white women and the more intelligent Negro women kept away from the community. In the second place, at the end of the book, some very brief statements are given about other mixed groups - for example, the Rivers, and there is nothing in the history which shows anything pathological about this very much larger group than the Wins. Whether the low mental and social status of the Wins is due to the economic and social status surrounding their lives, or whether their economic and social circumstances are due to their low mental level, cannot be decided on any of the data presented.

Let them take a few of the Win infants, immediately after birth, and, by an appropriate sum of money, obtain the consent of their parents to relinquish their care; let these infants then be placed in social groups and under social circumstances where they will have the full benefit of civilization, its schools, its hospitals, its workshops, and, above all, its [begin italics]mores[end italics]. A few such experiments will be worth all the group studies that can be made from now to Doomsday, and will prove something, whereas these studies are mere recountings of the same things over and over again.
