12 THE LEWIS BROOKS MUSEUM. 



Division II. — Paleontology. 



The specimens of fossil plants and animals are about 

 8,000 in number, and are equally distributed throughout 

 the several geological formations. Each specimen is mount- 

 ed on a block with a printed label, giving the generic and 

 specific name, the geological horizon and the locality. The 

 arrangement is a chronological one, the fossils of each great 

 geological period being grouped together in zoological and 

 botanical order. 



The collection is rendered more complete by the addi-
