The Races of Man: An Outline of Anthropology and Ethnography
“ This language is not at all superseded by Spanish; on the contrary, the Whites learn it, and several Quechua words: guano, pampa, condor, quina, have found their way into the languages of all civilised nations. [644] The principal tribes are: the Huancas to the north-east of Lima, the Lamanas near Trujillo, the Incas in the vicinity of the Rio Apurimac, the Aymaras of the high table-lands of Bolivia (600,000 individuals, of whom two-thirds are of pure blood) .In spite of the diversity of dialects all the Quechuas and Aymaras present a remarkable uniformity of physical type. ”
