Mrs. Audubon, meanwhile, had taken lodgings in London, but that city being no more to her taste than to her husband's, she joined him, and they travelled together till October, when to Audubon's joy he found himself at his old lodgings at 26 George St., Edinburgh, where he felt truly at home with Mrs. Dickie; and here he began the "Ornithological Biography," with many misgivings, as the journal bears witness: "Oct. 16, 1830. I know that I am a poor writer, that I scarcely can manage to scribble a tolerable English letter, and not a much better one in French, though that is easier to me. I know I am not a scholar, but meantime I am aware that no man living knows better than I do the habits of our birds; no man living has studied them as much as I have done, and with the assistance of my old journals and memorandum-books which were written on the spot, I can at least put down plain truths, which may be useful and perhaps interesting, so I shall set to at once. I cannot, however, give _scientific_ descriptions, and here must have assistance." His choice of an assistant would have been his friend Mr. William Swainson, but this could not be arranged, and Mr. James Wilson recommended Mr. William MacGillivray.[45] Of this gentleman Mr. D. G. Elliot says:[46] "No better or more fortunate choice could have been made. Audubon worked incessantly, MacGillivray keeping abreast of him, and Mrs. Audubon re-wrote the entire manuscript to send to America, and secure the copyright there." The happy result of this association of two great men, so different in most respects as Audubon and MacGillivray, is characterized by Dr. Coues in the following terms ("Key to North American Birds," 2d ed., 1884, p. xxii): "Vivid and ardent was his genius, matchless he was both with pen and pencil in giving life and spirit to the beautiful objects he delineated with passionate love; but there was a strong and patient worker by his side,--William MacGillivray, the countryman of Wilson, destined to lend the sturdy Scotch fibre to an Audubonian epoch.[47] The brilliant French-American Naturalist was little of a 'scientist'. Of his work the magical beauties of form and color and movement are all his; his page is redolent of Nature's fragrance; but MacGillivray's are the bone and sinew, the hidden anatomical parts beneath the lovely face, the nomenclature, the classification,--in a word, the technicalities of the science."
