Bates lived and studied in Amazonian South America for a total of eleven years, and is still regarded as one of the world's pioneering naturalists and entomologists. This classic two-volume work elucidates his concept of mimetic resemblance--known to this day as "Batesian mimicry"--and displays his significant contribution to the early development of the theory of natural selection.This is a reprint of the Bates family copy, the exclusive property of the Natural History Museum, and includes a family tree of the Leicester branch of Bates family. The volumes are richly illustrated with numerous plates and a foldout map of Bates' journey along the Amazon.
