Paleontology. 10,000 catalogued numbers, with 50,000 (esti- 

 mated) not yet catalogued, 500,000 (estimated) specimens in all; 

 including about 2000 type specimens representing about 1000 

 species. The most important collections are, the Gurley collec- 

 tion, the James collection, the Faber collection, the Sampson col- 

 lection, the Washburn collection, the Van Home collection and 

 the Weller collection. The formations best represented are the 

 Paleozoic of the Mississippi and Ohio valleys. 



In yertebrate paleontology, there are nearly 500 catalogued 

 specimens, with a smaller number yet uncatalogued, for the 

 most part collected under the direction of the late Professor 

 Baur, or obtained by purchase. The larger part of these are 

 from the Permian of Texas and Illinois and the Laramie Cre- 

 taceous of Wyoming, with others from the White River 

 Oligocene, the Kansas Niobrara Cretaceous and from Europe. 



Duplicates for exchange from the Niagara group of Waldron 

 Ind. 



Mineralogy. 2000 specimens, best representing the commoner 

 minerals and the tellurids and intended to illustrate chiefly the 

 crystallographic deyelopment of minerals. 



Economic mineralogy. 3000 specimens covering a wide range. 



Lithology. 2500 specimens, embracing igneous, sedimentary 

 and metamorphic rocks, but chiefly the former; and intended to 

 illustrate the whole range of rocks. 



Economic geology. A large series of ores and other mining 

 products, representing the leading mining districts of the United 

 States and of many foreign countries. 



Geology. A systematic series of fossils arranged on a strati- 

 grax)hic basis, illustrating the successive faunas and floras.
