Wilson's published lists of subscribers show 449 names, calling for 458 copies, more than half of which were taken by residents of Pennsylvania, New York and Louisiana; 70 were subscribed for in Philadelphia, chiefly by business men, artists, and "those in the middle class of society;" New Orleans in seventeen days gave him 60 subscribers; Europe supplied 15, among whom were William Roscoe, later a patron of Audubon, and Benjamin West, the artist. Wilson figured and described 278 species of American birds (within the limits of the United States), of which 56 were supposed to be new, and the total number, given by Wilson and Ord, is said to be 320. Twenty-three species were erroneously supposed to be identical with their European counterparts, yet all of Wilson's birds except the "Small-headed Flycatcher," referred to at the end of this chapter, have been identified. Considering the time and the difficulties under which he labored, his mistakes were remarkably few. [188] See Vol. I, p. 340. [189] See a letter to Professor S. S. Haldeman, dated February 6, 1879, in _Penn Monthly_, vol. x (Philadelphia, 1879). [190] _Ornithological Biography_ (Bibl. No. 2), vol. i, p. 437. [191] _Sketch of the Life of Alexander Wilson, Author of the American Ornithology_, by George Ord, F. L. S. &c. pp. i-cxcix, Philadelphia, 1828; taken from vol. i of an octavo edition of Wilson, edited by Ord, and issued by Harrison Hall, in three volumes, at Philadelphia in 1828-29, with folio atlas of plates reproduced from the original work; see Note 187, _supra_. [192] See Ord's charge of plagiarism against Audubon (Bibl. No. 145) in the _Proceedings of the American Philosophical Society_, vol. i (1840). So far as could be ascertained in the summer of 1915, Wilson's diary of 1810 was not in the possession of any library or scientific society in Philadelphia, nor was it in the large collection of books which was given by Ord to the College of Physicians and Surgeons of that city at the time of his death in 1866. [193] The bracketed lines are from Waterton, who once stated that he had examined the original.
