236 REPORT OF NATIONAL MUSEUM, 1890. 



bers of the IT. S. Geological Survey, is now in my charge at the Museum, 

 and ready to he recorded in the Museum registers and officially turned 

 over to its keeping. Ou account of the lack of any Museum assistant 

 this work has been impracticable, and can not be undertaken until some 

 one is detailed by the Museum for this work. 



I have, during the past year, published two papers, both of which 

 have a direct bearing upon my official work. These are mentioned in 

 the Bibliography.
