"the separate endogamous tribes are nearly as numerous, and they are in some respects as rude, as the separate exogamous tribes." He goes even farther, declaring that among a variety of tribes, belonging to "one and the same original stock," endogamy and exogamy are found existing side by side.[265] [258] _Principles of Sociology_, I, 641 ff.

In his second series of _Studies_, 74, 111, MCLENNAN defends his view as to the prevalence of female infanticide and presents a mass of facts relating to it among many peoples. FARRER, _Early Wedding Customs_, 224, denies that infanticide is the cause of exogamy. [260] SPENCER, _op. cit._, I, 646.
