has been engaged to classify and label the Mexican archaeological 

 specimens, and has already completed a portion of the work. Much 

 additional archaeological material has been transferred during the 

 year to the new building, three additional cases and six large 

 tables being provided for its reception. 



A boiler has been erected in the engine-house and the heating 

 plant of the new building is thus rendered practically complete. 



The west end of the main floor of the old museum has been 

 separated by a partition of glass and woodwork, thus forming a com- 

 modious apartment which will soon be occupied by the Entomo- 

 logical Section. New radiators have been provided for heating the 

 same, while radiators have also been placed in the rooms formerly 

 occupied by the Wm. S. Vaux Collections, east of the library gallery. 



Early in the year the entire collection of bird skins was removed 

 from the cramped quarters in the library and cellar and placed in 

 the southeast room, formerly devoted to the Wm. S. Vaux Collections, 

 which now forms an excellent study room for those engaged in ornitho- 

 logical investigation, while the adjoining room has been used as a gen- 

 eral work room for the taxidermist and others engaged in the prepara- 

 tion of specimens. The northeast room on the same floor has been 

 devoted to the use of the artists and transient workers. The basement 

 of the new building has also been fitted up for the use of the taxi- 

 dermist, and all the larger work has been done there. The transfer 

 of the west end of the main floor of the old museum to the Entomo- 

 logical Section has necessitated considerable rearrangement of cases, 

 and the removal of the osteological collections to the second floor of 

 the new building, while the mammal and fossil cases are necessarily 

 much crowded. This condition is, however, only temporary, and as 

 soon as cases can be provided the entire series of mammals will be 

 transferred to the new building, leaving ample room for the display 

 of the palreontological collections. 



Rev. Dr. L. T. Chamberlain has generously provided a second 

 fine case for the Lea Collection of Eocene Fossils, and has employed 

 Prof. G. D. Harris during the year to make a careful study of the 

 original Lea type collection, with the result that the whole is now 

 entirely rearranged on specially printed labels, and all the type 

 specimens carefully designated. 



Mr. C. W. Johnson has been engaged, also by the Rev. Dr. 

 Chamberlain, on another expedition to the Eocene formation in
