stand the chemical composition of the different mineral species in 

 the collection. These labels are not all in place yet, but will be in 

 a few weeks. 



The addition of the two sections of fossilized wood, and a large 

 mass of Zinc ore, Calamine, and a few other large, showy speci- 

 mens, have added much to the appearance of the collection; but 

 many more are needed in order to have it meet the requirements 

 of a large public collection. 



Conchological Collection. Wolfe Collection. — -The label- 

 ing and numbering of this collection is now nearly completed, and 

 will be finished early in the coming year. It now presents quite 

 an attractive appearance, and is rapidly becoming a very useful 

 collection, if one can judge of it by the number of people who use 

 it for the identification of specimens. There are many additional 

 specimens of shells belonging to the Museum, which will be 

 incorporated in the collection. 



Economic Collection. — Jesup Collection of Ornamental and 

 Building Stone. Much labor has been done on this collection dur- 

 ing the year. Black-walnut blocks have been furnished for the 

 Stones, and for holding the labels; when these latter shall have 

 been put in proper shape for placing on them, they will be put in 

 position. A catalogue of this collection was prepared and printed 

 in the journal Stone. The geological position of the specimens 

 was added from information obtained by this office. 



Guides. — A new and enlarged edition of the Guide to this de- 

 partment was prepared during the autumn, which contains about 

 eighteen pages of new matter. Copies of this were placed on sale 

 in the building during the holidays. 



DEPARTMENT OF MAMMALS AND BIRDS. 



[Under the charge of Mr. J. A. Allen.] 



Mammals. — The additions to the collection of Mammals include 

 15 mounted specimens, 14 of which are Monkeys, all but one ac- 

 quired by purchase; 165 skins and 180 skulls, mostly purchased; 

 37 specimens received in the flesh, seven of which were presented 

 by Mr. Frank J. Thompson, six were purchased, and the remaining 

 24 were received from the Central Park Menagerie, through Dr. 

 W. A. Conklin, Superintendent. The specially noteworthy addi- 

 tions are the Chimpanzee (" Crowley ") from the Central Park 

 Menagerie ; two Bison skins and a head, purchased ; two full- 

 grown Florida Manatees (male and female), purchased ; two group 

 pieces, representing the Flying Squirrel and the Red Squirrel, pre- 

 sented by Mrs. Robert L. Stuart. Much material has also been 

 gathered for future groups of Mammals.
