The Published Writings of George Newbold Lawrence, 1844-1891U.S. Government Printing Office, 1892 - 124 Seiten The beneficial influence of the labors of Mr. Lawrence on the progress of American ornithology has been great and undisputed, but it was particularly among the avifauna of the West Indies, Mexico, Central and South America that his most strenuous efforts were exerted. A scrutiny of the titles of his numerous papers will fully indicate the wide scope and excellent character of the work of this veteran ornithologist. |
