DEPARTMENT OF ZOOLOGY. 
The collections of the Department of Zoology are very exten- 
sive, covering fully this field of science from Protozoa to man. 
The classification begins with the lowest forms of life, in Hall 
24, and follows in ascending scale through the halls in serial or- 
der, ending in a special geographical collection (Hall 19) from the 
Galapagos Islands. The collections are especially rich in several 
divisions, as for example : the Sub-kingdom Mollusca, in which is 
nearly every family, genus and sub-genus, at present described; also 
the collection of corals {Sub-kingdo?n Ccelenterata)y which is un- 
usually rich in species of great interest. The Osteological collec- 
tion is one of great value, and contains many very rare specimens. 
The classification adopted is essentially that of the best Ger- 
man and French savants^ with such additions as modern American 
investigations have made necessary.
