There have been sent out from the Division of Geology during this

 tigation. For the last-named purposes there have been loaned during 

 the 3'ear, from the Division of Geology: 



To T. Nelson Dale, Pittstield, Massachusetts, 6 specimens of roofing 

 slates and thin sections.

 the Chemical and Physical Department of the U. S. Geological Sur- 

 vey, to the Division of Koads of the Department of Agriculture, and to 

 the Bureau of Soils of the same Department. Samples of the Putnam 

 County, Georgia, and Admire, Kansas, meteorites were sent to Dr.

 (Dr. Handlirsch), 562 Carboniferous insects. 



Portions of collections in the section of vertebrate paleontology 

 have been studied by Dr. E. C. Case, Milwaukee, Wisconsin; Prof. 

 S. W. Williston, University of Chicago; Dr. J. B. .Hatcher, Carnegie 

 Museum, Pittsburg, Pennsylvania; Prof. H. F. Osborn, of the Amer- 

 ican Museum of Natural History in New York City; and Dr. John 

 M. Clarke, State paleontologist of New York. 



The paleobotanical collections, as usual, have been contiiuially 

 availa])le to the paleobotanists of the U. S. Geological Survey. In 

 addition. Dr. Arthur Hollick, of the New York Botanical Gardens, 

 has on several occasions visited the Museum in connection with his 

 work on the island series of the Upper Cretaceous. 



PRESENT CONDITION OF (X)LLECTIONS. 



It may be safely stated that, as a whole, the collections are in better 

 condition than ever before. The improvement has been constant, and 

 though not as rapid as one could wish, is fairly satisfactory— perhaps 

 as satisfactory as can be expected in the present building. Naturally
