Weddell travelled for five years in Peru, Paraguay and Bolivia, identifying fifteen different species of "fever-bark," from which quinine is obtained. He brought back specimens for the Jardin des Plantes, from which chinchona forests were established in the East Indies. The map and the last three plates, which illustrate bark specimens, are beautifully hand-colored. In original printed wrappers, reinforced, repaired, and rebacked. Corners of the first vii pages chipped and dog-eared, not affecting printed area. Small chips to endleaves. Neat owner's signature on title. A very good copy of an important book.
