further govemment-al work, Cope practically superseding him in that 

 respect. Cope was a prodigious worker, as is attested by his many 

 volumes and reports on vertebrate fossils published by various 

 branches of the Government. As he also accompanied expeditions,, 

 the Government collections were greatly enriched by his specimens 

 as well as by his paleontological studies and publications. 



Cope was superseded by Prof. O. C. Marsh in 1882, who became 

 vertebrate paleontologist for the United States Geological Survey,, 

 and for 10 years he brought together collections and described ma- 

 terials that together form the most notable contribution ever made 

 to the development of the Division of Vertebrate Paleontology in the' 

 National Museum. 



Dr. Oliver P. Hay, although never ofRcially connected with the Na- 

 tional Museum, nevertheless contributed much to the development of 

 vertebrate paleontology in this Institution (1912-30). Appointed re- 

 search associate in the Carnegie Institution of Washington in 1912,. 

 he was provided office space in the Division of Vertebrate Paleontology,, 

 which he occupied until his death on November 2, 1930. His bibliog- 

 raphy contains no less than 29 papers that were based wholly on- 

 Museum specimens. In addition to his research,, he made raany gifts 

 to the collections and was responsible for the acquisition of a number 

 of unique specimens. It was during this period that he compiled his 

 Second Bibliogi'aphy and Catalogue of the Fossil Vertebrata of North 

 America and the three volumes on the Pleistocene of North America! 

 and Its Vertebrated Animals. 



Dr. Remington Kellogg, while still a member of the Biological 

 Survey staff of the Department of Agriculture (1920-28), undertook 

 the scientific investigation of the fossil cetacean collections of the 

 National Museum, this work being done outside of his official duties 

 and supported to some extent by grants from the Carnegie Institu- 

 tion of Washington, These studies have been continued since his 

 affiliation with the Museum in 1928, and his energetic interest has 

 been a very important factor in developing the marine fossil mam- 

 mal collection to a point where it ranks first among American col- 

 lections of these animals. 



Dr. Charles R. Eastman, under the auspices of the Smithsonian 

 Institution, spent a year (1914) in the study of the fossil fish collec- 

 tion, rendering valuable service in publication,^^ identification, and 

 rearrangement. 



Dr. Alexander Wetmore began the study of fossil birds prior to 

 his appointment as Assistant Secretary of the Smithsonian Institu- 

 tion in 1925, and since then he has published continually, much of 

 his work being based on the Museum's collections. Through his;
