Report of the President. 17 



Labels were supplied for all new specimens of Mammals, and 

 many old labels have been replaced to conform to the recent 

 changes in nomenclature ; the Bird Collection has received similar 

 attention. The gain of the year is summarized as follows : 

 Mammals, 872; birds, 1356; reptiles, 146; fishes, 150. 



Department of Geologv and Invertebrate Zoology. — 

 The work of the department has mainly been devoted to the care 

 of the Shell Collection ; labels have been prepared for the general 

 collection, which has required the revision and preparation of 

 about 4500 labels. In bringing together the material, it is dis- 

 closed that the case room is insufficient for the proper installation 

 of this branch of our collections, and it will require therefore the 

 assignment of more space for the purpose. 



Considerable attention has also been given to the specimens of 

 Invertebrate Zoology in the way of mounting and preparing 

 specimens brought in during the year. The corals and sponges 

 have been displayed to better advantage. 



Department of Vertebrate Palaeontology. — In referring 

 to this department, a portion of the report of its Curator, Prof. 

 Henry F. Osborn, is incorporated, for the purpose of more clearly 

 expressing the gratifying results achieved through the efforts of 

 the force engaged in field work. The field parties consisted of 

 Dr. J. L. Wortman, Dr. W. D. Matthew and Mr. W. W. Granger 

 of the Museum ; and Messrs. Brown and Menke of Kansas Uni- 

 versity. The Curator also spent a short time in field work. 



" In the Department of Vertebrate Palaeontology we have con- 

 tinued to devote the greatest care and study toward arousing the 

 interest of the public in our exhibits. Two large charts have 

 been made, showing clearly the succession of animals in the 

 ascending series of rocks on this continent. 



"Three years ago we first took the camera into the field, and 

 began to secure a series of photographs of the sites where the 

 different types of extinct animals are found. We have now taken 

 advantage of the negatives, and are having them enlarged and 

 carefully colored as window transparencies, thus conveying to the 

 visitors a clear idea of the Bad Lands. From over two hundred 

 negatives, we propose to fill all the windows in the Hall with 

 scenes taken at or near the specimens exhibited.
