And hence it seems a valid and necessary conclusion that at the time when the family terms of relationship came into existence, the clan sentiment of kinship was stronger than the family sentiment; that is, a boy was taught or made to feel that all the women of the clan of about the same age as his mother were as nearly akin to him as his own mother, and that he should regard them all in the same relation.

And similarly he looked on all the men of the clan of an age enabling them to be his fathers in the same light as his own father, and all the children of or about his own age as his brothers and sisters.

The above seems a necessary conclusion from the existence of the classificatory system of relationship, which is very widely spread among savages, and if admitted, it follows that the sentiment of kinship within the clan was already established when the family terms of relationship were devised, and therefore that the clan was prior to the family as a social unit.

This conclusion is fortified by the rule of exogamy which prohibits marriage between persons of the same clan between whom no blood-relationship can be traced, and therefore shows that some kind of kinship was believed to exist between them, independent of and stronger than the link of consanguinity.

Further, Mr.Hartland shows in _Primitive Paternity_ [92] that during the period of female descent when physical paternity has been recognised, but the father and mother belong to different clans, the children, being of the mother's clan, will avenge a blood-feud of their clan upon their own father; and this custom seems to show clearly that the sentiment of clan-kinship was prior to and stronger than that of family kinship.
