This volume contains extracts, chiefly in an unknown hand (probably Charles Waterton), from Ord's letters, 1831-1835, criticizing Audubon as a man and as a naturalist. Ord wrote the last part of the volume (signed and dated June 29, 1838), and there are manuscript comments by Charles Waterton.

This material relates to Alexander B. Grosart's biography of Wilson. There are notes and copies of letters and documents, including a copy of Wilson's will. There is one poem by Wilson, "The Last Wish," and an 1806 letter to William Bartram.
