Originally published during the early part of the twentieth century, the Cambridge Manuals of Science and Literature were designed to provide concise introductions to a broad range of topics. They were written by experts for the general reader and combined a comprehensive approach to knowledge with an emphasis on accessibility. Prehistoric Man by W. L. H. Duckworth was first published in 1912, and reissued as this second edition during the same year. The volume contains an account of the earliest phases in the development of humanity, beginning with the precursors of Paleolithic man and ending at the time of the Aurignacian culture.
