Descent of Man (A. L. Burt edition)
Illustrations from Charles Darwin's The Descent of Man, And Selection in Relation to Sex. U.S. reprint of the second edition, published by A. L. Burt Company. Part of Burt's Home Library, "Popular literature for the masses, comprising choice selections from the treasures of the world's knowledge" ($1.25 per volume). Exact date of publication is uncertain - libraries list the book as being from 1874, but there is no date on the cover page, and apparently the second edition was not actually published in England until 1882.
