ANTHROPOLOGY AND ETHNOLOGY Asia presents to the anthropologist the widest range of different types of any of the continents. So vast is its area, so varied its climate, that ethnic types of all kinds are found within its borders. This being so, no complete anthropologic or ethnologic study of Asia as a whole is yet possible; the work of research and classifi cation is still proceeding. Old divisions are found to be unsuited to new developments in our knowledge, and surveys, official and private, are annually penetrating old fields to emerge with new data.
