Page "John James Audubon" Paragraph 50

Audubon's final work, on mammals, was the Viviparous Quadrupeds of North America, prepared in collaboration with his good friend Rev John Bachman of Charleston, South Carolina, who supplied much of the scientific text.

His son John Woodhouse Audubon drew most of the plates.

The work was completed by Audubon's sons and son-in-law and was published posthumously.
