IN the discussion on the future of anthropology at the centenary meeting of the Royal Anthropological Institute, as reported in NATURE of November 20, there seems to have been a serious misconception of the natural scope of physical anthropology. In my presidential address to Section H of the British Association in 1939, I discussed the subject at some length, and suggested that the future of this important science may be seriously jeopardized if it is not allowed to develop naturally along progressive lines.
