First edition, second issue with the "htat" misprint on the first line of page 208. The author's third major work of evolutionary theory, following On the Origin of Species (1859) and The Descent of Man (1871). Initially intended as a chapter in The Descent of Man, The Expression grew in length and was published separately in 1872. This book concerns the biological aspects of emotional behavior, and Darwin explores the animal origins of such human characteristics as the lifting of the eyebrows in moments of surprise and the raising of the upper lip in an aggressive sneer. Octavo: vi, 374 p. with 7 heliotype plates (3 folding), 21 textual figures, and 4 p. publisher's ads. Original green cloth binding, with gilt stamping, blind-stamped borders, and black endpapers. Some marginal creasing (not affecting the images) and minor foxing to the folding plates. Period previous owner's pencil signature to the top of the title page. The hinges are just starting and still quite sound. A bit of wear to the corners and tips; else very good.

In this seminal work, Charles Darwin examines the genetic similarities among humans and animals, providing insights into the biological origins of their emotions.
