ABSTRACT
In my last lecture I began the demonstration of the dependence of the classificatory terminology of relationship upon social institutions by showing how a number of terms used in several parts of Melanesia have been determined by the cross-cousin marriage. I showed that in places where the cross-cousin marriage is practised there are not merely one or two, but large groups of, terms of relationship which are exactly such as would follow from this form of marriage. To-day I begin by considering other forms of Melanesian marriage which bring out almost as clearly and conclusively the dependence of the classificatory terminology upon social conditions.
