[94] Isaac Lea, naturalist and Philadelphia publisher; Mr. Lea was a member of the firm of Messrs. Carey & Lea, at one time the principal proprietors of Wilson's American Ornithology, and it was thought that the prejudice which he manifested towards Audubon and his friends was traceable to his desire to maintain the sales of that work. His attitude was compared with that of Judge Hall, whose brother, Harrison, was also an interested publisher. See [Vol. I, pp. 223] and [281].

[97] William John Burchell (1782?-1863), an indefatigable collector and explorer, especially in Africa and Brazil; the zebra, Equus burchelli, and many animals and plants which he discovered have been dedicated to him.

[101] But three other letters of Audubon to Swainson, after this date, are noted by Albert Günther ([Bibl. No. 204]) in the Proceedings of the Linnæan Society, 112th session (1900): one of "6 June, 1831," announces Audubon's prospective return to America in August of that year; another, dated "6 Dec. 1837," asks for the loan of some bird skins; and the last of "11 Jan. 1838," is reproduced in [Chapter XXXII]. Swainson is said to have been negotiating at this time with Charles L. Bonaparte in reference to a joint compilation for a work on the birds of the world; Bonaparte estimated that there were then between 7,000 and 8,000 known species to be characterized, but Swainson's terms were not satisfactory, and nothing came of the project. To the above list should be added the letter, evidently misdated, of "April 28th. 1831," soon to follow.
