Two text volumes, with two folding maps, 52 lithograph plates, and many additional illustrations in the text; and two atlas volumes containing five large folding maps, all in very good condition.

Maps have some browning at the folds and some small splits, but are very good overall. This American expedition was organized by the U.S. Navy Department and conducted in 1851-52 to determine the feasibility of opening the region to American agricultural and slaveholding interests. The explorers traveled to Chile and then to Lima, Peru, where Herndon pushed into the upper Amazon and Gibbon turned south through Bolivia and into Brazil. The two groups met up again in Serpa, Brazil and continued down the Amazon to Para. Hill (803) describes the work as "a minute, accurate, and very interesting study on the aborigines of the Andes and on the geography of the Amazon and its tributaries" and Borba de Moraes (p. 336) calls it "an excellent book on the regions cited."
