There is no 'problem' with Indo-Tibetans per se.  The problem examined by the author is that of determining the evolution and inter-relationships of the races that inhabit the foothills of the Himalayas.  His thesis is extremely detailed and extends into dress, housing, religious practices and material culture.  Hardback.  160 pages.  Line drawings plus thirty-eight b&w plates and a fold-out map of Nepal, Sikkim, Bhutan and Assam showing tribal distribution.  Lacks dustwraper, otherwise good clean condition.  Cat No 2494
