Included in this rare text is a comprehensive catalogue of the multifarious inhabitants of the banks of the mighty river Brahmaputra from Lowe Tibet to the Bay of Bengal. This comprehensive ethnological database includes observations about six hundred individuals belonging to over thirty separate tribes, the author having taken twenty to thirty physical measurements of each member for inclusion in this book. Containing for the first time a systematic record of such attributes as skin and eye colour, coupled with photographs taken by the author himself, this book constitutes an ethnological first and, as such, will appeal to students of history and ethnology alike. Laurence Austine Waddell was British explorer, army surgeon, professor of Chemistry and Pathology, amateur archaeologist, and author. Originally published in the Journal of the Asiatic Society of Bengal in 1900, this rare book is proudly republished now with a new introductory biography of the author.
