338 PROCEEDINGS OF THE NATIONAL MUSEUM vol.90 



In recent years, Dr. Kemington Kellogg, through his extensive 

 researches on the Cetacea, has been the outstanding contributor to the 

 building up and development of the collections in this important gi'oup 

 of mammals. 



INFLUENCE OF EXPOSITIONS 



Although the Smithsonian Institution has participated in prac- 

 tically all the expositions of this country and many abroad, beginning 

 with the Centennial in Philadelphia in 1876,-^ the Division of Verte- 

 brate Paleontology was not called upon to contribute to these exhibi- 

 tions until 1895. Since then, hovrever, it has participated in the follow- 

 ing: The Cotton States and International Exposition, Atlanta, Ga., 

 1895; the Trans-Mississippi and International Exposition, Omaha, 

 Nebr., 1898; the Pan-American Exposition, Buffalo, N. Y., 1901; the 

 Louisiana Purchase Exposition, St. Louis, Mo., 1904; the Lewis and 

 Clark Exposition, Portland, Oreg., 1905; the Sesquicentennial Expo- 

 sition, Philadelphia, Pa., 1926; and the Texas Centennial Exposition, 

 Dallas, Tex., 1936-37. 



Participation in these expositions of national and international 

 scope has yielded noteworthy advantages in the fact that the work 

 of the division was made known to the people at large and in the 

 opportunities offered by direct appropriations that could be expended 

 for the purchase of specimens, the making of models, restorations, 

 and paintings illustrative of extinct life. This illustrative material 

 and a considerable number of choice specimens (listed below) have 

 thus been added to the permanent collections : 



1895, Atlanta : A complete model restoration of the skeleton of BasUosaurus 



cetoides, life size. 

 1898, Omaha: Lisbon A. Cox collection of Paleozoic fish remains purchased. 

 1901, Buffalo : A restoration in oil (8 by 15 feet) of Triceratops, painted by 



Charles R. Knight, W. K. Stone, and Joseph Gleeson. Model restoration 



life size of Trico-atops skeleton. Skeleton of Hesperornis regalis and 



Dinomis crassus purchased. 



1904, St. Louis : Life-size restoration of Stegosatirus stenops. Skeleton of Mas- 



todon amerlcanus. Skeletons of Ichthyosaurus quadricissus, Rhani- 

 phorhi/nchus pliyllurus, Stenosaurus hoUensis, and many fishes of large

21 Dr. J. Leidy (Jouin. Acad. Nat. Sci., Philadelphia, vol. 8, p. 213) stated that a last 

 molar of Elephas columM from Beaufort, S. C, was included in the exhibit made by the
