Naturalists in paradise

Alfred Russel Wallace, Henry Walter Bates and Richard Spruce were English naturalists who went to Amazonia 150 years ago. In addition to their huge contributions to knowledge of the Amazonian environment, each is particularly famous for one discovery. Wallace is acknowledged as a co-discoverer, along with Charles Darwin, of the theory of evolution. Bates discovered protective mimicry among insects, a phenomenon named after him. Spruce transported the quinine-bearing Cinchona tree, the most important medicinal plant of the 19th century, to India, where it saved countless lives from malaria. This book combines all three young men's experiences of the Amazon, drawing heavily on their own letters and books.
