The Expression of the Emotions in Man and Animals (Cambridge Library Collection - Darwin, Evolution and Genetics)

"Even cows, when they frisk about from pleasure, throw up their tails in a ridiculous fashion." So writes Charles Darwin in his magnum opus on how humans and animals display such emotions as fear, anger, disdain, and pleasure; it is work that has in most respects been sustained by later scientific research. First published in 1872, Darwin's greatest work was never issued in quite the shape its author intended: bits and pieces were left out of subsequent printings, most of them released after Darwin's death, and later editors made additions to suit the intellectual fashion of their times. This definitive edition, heavily annotated, brings us the book that Darwin would have wanted, and it is essential to any naturalist's library.
