Principles of Geology. Vol 2

As important to modern world views as any work of Darwin, Marx, or Freud, Lyell's *Principles of Geology* has never before been available in paperback. In the second of three volumes, Lyell (1797-1875) continues his uniformitarian argument of Volume I-the physical features of the earth are endlessly fluctuating around a stable mean-but focuses on organic rather than inorganic processes. Volume II is widely known because of its influence on Darwin, who took the book on his famous *Beagle* voyage and was stimulated by Lyell's extensive treatment of biological history and diversity.
