First edition in the rare original parts of Audubon's final great natural history work, with plates and descriptions of the quadrupeds of the United States including Texas, California and Oregon, as well as part of Mexico, the British and Russian possessions and Arctic regions. Audubon's collaborator on the Quadrupeds was the naturalist and Lutheran clergyman John Bachman who had studied quadrupeds since he was a young man and was a recognized authority on the subject in the United States. The two began their association when Audubon stayed with Bachman and his family in Charleston for a month in 1831; this friendship was later cemented by the marriage of Victor and John W. Audubon to Bachman's daughters, Maria and Eliza. Audubon knew Bachman's contribution to the Quadrupeds would be crucial, and endeavored to convince his friend to lay aside his fears about the project. Audubon was eager to begin what he felt could be his last outstanding achievement in natural history, but Bachman was more cautious and worried that they were entering a field where "we have much to learn." Audubon persisted in his efforts to get him to take.
