During the half year Bulletin 10, U. S. Geological Survey, was issued. 

 This is based upon material belonging to the museum of Cornell Uni- 

 versity. Arrangements, however, have been made to obtain a dupli- 

 cate collection from the university. 



The total number of specimens on hand April 1, 1885, according to 

 actual count, and exclusive of some not then unpacked, was 72,649, a 

 table * of which was furnished to you with my report for the month of 

 April. 



WORK ON THE COLLECTIONS. 



The direct work on the collections of the Museum has been the iden- 

 tifying, recording, and labeling of the material menMoned under the 

 accessions, and the continuation of the arrangement and labeling of 

 the old collections of the Smithsonian Institution. Not having an as- 

 sistant who can give all of his time to the work, progress has been slow 



* A similar table will be found on p. 208 of the Museum Report for 1884.
