Report of the President. 1 7 



Valuable exchange collections have been received from the 

 British Museum, and the Museums of Moscow, Bucharest, 

 Tubingen and Buenos Aires. The mounting of new material 

 has continued under Mr. Hermann. 



Five expeditions have been maintained in the field: in Mon- 

 tana, Colorado, Wyoming and South Dakota. The most notable 

 additions to the collections by these expeditions are a complete 

 skeleton of an Upper Miocene Three-toed Horse, a fine skull 

 and jaws of the horned Dinosaur Triceratops (skull between 

 seven and eight feet long) and three complete skeletons of a 

 rare Cretaceous Reptile, Champsosaurus. 



The establishment of a fund by a member of the Board 

 of Trustees, Mr. William C. Whitney, for providing material 

 to illustrate the origin and development of the horse, has 

 produced immediate results of the highest importance, and 

 stimulated the work in many cognate lines. 



The purchase of the Cope Collections has been effected, 

 and all this material is now the property of the Museum. The 

 collections include fossil reptiles, amphibians and fishes, pre- 

 sented by your President, and the Pampean Collection of fossil 

 mammals of South America, presented by a number of the 

 Trustees of the Museum. The great value of these collections 

 has been noted in former reports. They contain a large 

 number of complete or nearly complete skeletons of rare fossil 

 species, among which the Sabre-Tooth Tiger, the Carnivorous 

 Dinosaur, Duck-billed Dinosaur, and Amphibious Dinosaur, 

 are now being prepared for exhibition. 



Department of Anthropology. — In order to have the 

 halls in readiness for the meeting of the International Congress 

 of Americanists, every effort was made by the officers and 

 assistants of this department to arrange and label the collec- 

 tions. The collections were studied with interest by the 

 members of the Congress during the week of the meetings, 

 and many remarks were made upon their scientific importance 

 and value.
