Dinosaurs. His most recent memoirs include those on the gigantic 

 carnivorous Dinosaur Tyrannosaurus and on the integument of the 

 Iguanodont Dinosaur Traohodon, both astonishing discoveries. 



While engaged in descriptive work, Professor Osborn has always 

 been keenly appreciative of its philosophical bearings, and he has 

 published many dissertations on the transmission of acquired 

 characters, mutations, adaptive variations, and allied subjects. In 



1894 he contributed to the Columbia University Biological Series 

 an important volume entitled From the Greeks to Darwin, which has 

 been several times reprinted, and has also been translated into 

 Italian. He discussed "Darwin and Palaeontology " in the volume 

 on Fifty Years of Danvinism, published by the Cambridge University 

 Press in 1909. He stated the biological conclusions drawn from his 

 study of the Titanotheres in a paper read before the National 

 Academy of Sciences in 1911 ; and more recently he addressed the 

 Paleontological Society of America on the "Origin of Single 

 Characters as observed in Fossil and Living Animals and Plants". 



Finally, Professor Osborn has made many valuable contributions 

 to popular scientific literature, and among the latest may be mentioned 

 his profusely and beautifully illustrated volume on the Men of the 

 Old Stone Aye, their Environment, Life, and Art, which was 

 published at the end of 1915. 



During the greater part of his career Professor Osborn has been 

 much occupied with administration in varied ways. From 1892 to 



1895 he was Dean of the Faculty of Pure Science in Columbia 

 University. Since 1881 his organization, in connection with the 

 American Museum, of a complete survey of the geological succession 

 of the higher vertebrates in North America, has produced a flourishing 

 school of vertebrate palaeontology, represented by Earle, Matthew, 

 Granger, Gidley, Loomis, Brown, Lull, Peterson, Gregory, and others. 

 In 1896 he took a very active part in the foundation of the New 

 York Zoological Park, under the auspices of the New York Zoological 

 Society, of which he has been President since 1909. He is also 

 a leading member of the New York Academy of Sciences, over which 

 lie presided in 1898-1900 ; and he has been a Trustee of the New 

 York Public Library since 1912. Among other offices, he has held 

 the Presidency of the American Morphological Society (1897), the 

 Marine Biological Association (1898-1900), the Audubon Society 

 (since 1910), and the American Bison Society (since 1914). Finally, 

 in 1914, he became a member of the Belgian Belief Committee. 



Professor Osborn has naturally received many honours both at 

 home and abroad. He has been admitted to several university 

 degrees already enumerated, and in 1914 he was awarded the 

 Hayden Gold Medal by the Philadelphia Academy of Natural 

 Sciences. He is a Foreign Member of the Linnean and Geological 

 Societies of London, the Cambridge Philosophical Society, the 

 Manchester Literary and Philosophical Society, and the British 

 Association. From frequent visits, indeed, he is almost as well 

 known to the scientific men of this country as to those of America, 

 and his personal charm has won for him a large circle of devoted 

 friends. Those who have visited him in his beautiful home amid the
