It is becoming an axiom in anthropology that what is needed is not discursive treatment of large subjects but the minute discussion of special themes, not a ranging at large over the peoples of the earth past and present, but a detailed examination of limited areas. This work I am undertaking for Australia, and in the present volume I deal briefly with some of the aspects of Australian kinship organisations, in the hope that a survey of our present knowledge may stimulate further research on the spot and help to throw more light on many difficult problems of primitive sociology.

We have still much to learn of the relations of the central tribes and their organisations to the less elaborately studied Anula and Mara. I have therefore passed over the questions discussed by Dr Durkheim. We have still more to learn as to the descent of the totem, the relation of totem-kin, class and phratry, and the like; totemism is therefore treated only incidentally in the present work, and lack of knowledge compels me to pass over many other interesting questions.
