Summary: IN his presidential address to the Section of Anthropology at the Winnipeg meeting of the British Association Prof. J. L. Myres asked the question “What happens to Englishmen in city ‘slums’?” or, in other words: How are the peoples of Britain adapting themselves to modern conditions? Are these conditions producing modifications in the racial constitution and qualities of the nation? The matter is one of importance to the older country, for more than three-quarters of the population now reside in urban districts, and to the newer, since in the course of time industries must concentrate in favourable localities and close aggregates of population necessarily arise.
