(The book from the Contemporary Science Series was Professor Letourneau's "Evolution of Marriage."

Westermarck (73-80), Letourneau (56-62), Ploss (I., 400-405), and others have collected abundant proofs.

"All over the earth," says Letourneau (137), "among all races and at all times, wherever history gives us information, we find well-authenticated examples of marriage by purchase, which allows us to assert that during the middle period of civilization, the right of parents over their children, and especially over their daughters, included in all countries the privilege of selling them.

We must not allow ourselves to be deceived by appearances, as in the case of the Moors of Senegambia, concerning whom Letourneau says (138) that a daughter has the right to refuse the husband selected for her, on condition of remaining unmarried; if she marries another, she becomes the slave of the man first selected for her.

" (Letourneau, 139.)

"For most insects," says Letourneau, "to love and to die are almost synonymous terms, and yet they do not even try to resist the amorous frenzy that urges them on."
