 the second portion of the famous collection brought 

 together by Professor Edward D. Cope, known as the 

 Cope Collection of Fossil Fishes, Auiphibians, Reptiles 

 and Birds. This was generously presented to the 

 Museum by President Morris K. Jesup in 1902. At 

 the same time the Panipcan Collection of Ajneghino, 

 Larroque and Bracket, originally exhibited at the Paris 

 Exposition in 1881, and there purchased by Professor 

 Cope, was secured for this Museum by the gift of 

 Messrs. H. O. Havemeyer, D. Willis James, Adrian
