the skeletal anatomy, and a paper describing new fossil turtles, with 

 notes on described species. He has continued work on the mono- 

 graphic study of the carnivorous dinosaur materials in the National 

 Museum collections, and it is hoped that this long delayed paper can 

 be brought to completion during the coming year. 



Dr. F. H. KnoM^lton has supervised the work of arranging and 

 labeling of the collections of Mesozoic and Cenozoic plants. He has 

 completed a memoir on geologic climates in which the paleobotanic 

 data was based on the study collections of the Museum, and has fin- 

 ished a bibliographic catalogue of Mesozoic and Cenozoic plants of 

 North America, which is now in course of publication by the United 

 States Geological Survey. 



Mrs. Eula D. McEwan, aid. resigned early in the fiscal year, but 

 with the appointment of Miss Lucile Simpson as her successor, active 

 work on the plant collections was resumed. Besides assisting in gen- 

 eral exhibition work, Miss Simpson has assembled all of the type 

 specimens of Tertiary plants and arranged them in final Museum 

 form. This particular collection is now located in one room and 

 the work is up to date. 



As in previous years, the collections have been studied by nu- 

 merous workers not connected with the Institution, and the methods 

 of installation, recording, and general system of management have 

 been matters of investigation by those engaged in or about to enter 

 upon similar work elsewhere. Among the more prominent of these 

 were the members of the British Educational Commission ; Prof. A. 

 F. Foerste, of Dayton, Ohio; Maj. C. J. Hamlin, director of the 

 Buffalo Society of Natural History; Prof. G. D. Harris, Ithaca, 

 New York; Dr. S. B. Howell, Princeton University; Dr. E. Ruede- 

 mann, of the New York State Museum; Dr. Thomas L. Watson, 

 State geologist of Virginia; Mr. Barnum Brown, of the American 

 Museum of Natural History ; Dr. Roy L. Moodie, of the University 

 of Illinois; Prof. E. W. Berry and Dr. Harvey Bassler, of Johns 

 Hopkins University; Miss Carlotta J. Maury, Dr. J. L. Wortman, 

 and Dr. O. P. Hay. 



Present condition of the collectio7is. — Both the exhibition and 

 study series in the division of systematic and applied geology are 

 in fairly good condition as regards arrangement, labeling, and rec- 

 -orcls. The division of mineralogy is, however, greatly behind and 

 will require much care and attention to bring it back to its original 

 standard. 



In the division of paleontology, both the study and exhibition col- 

 lections are now in better condition than ever before, although the 

 amount of material received for permanent preservation each year 

 exceeds the ability of the force to place it in final museum form. 

 The collections are, however, accessible for reference, and while
