Abstract
Opening ParagraphThe Rhodes-Livingstone Institute is attempting a comparative study of the tribes of British Central Africa and of the processes of change affecting their lives to-day. Social anthropologists have been sent to tribes selected both for the variety of forms in their indigenous social organization and for the different ways in which they have been absorbed in the modern world-system. Though we, of the Institute's staff, are spread over thousands of square miles, and have had very different trainings, we have tried to collect our data on comparable bases and to study similar problems. This short symposium, which opens what we have come to consider a crucial problem, is the first-fruits of our collaboration.
