WORK ON COLLECniONS. 



The direct work on the collections of tlie Museum has been the 

 recording, identifying', and labeling of the nuiterial mentioned under 

 '' accessions," and a continuation, as opportuiiity ollered, of the arrange 

 iMcnt of the old collections of the Smithsonian institution. The latter 

 work has been very limited, owing to the winter's [)Osition as i)aleontolo- 

 gist in charge of the paleozoic paleontology of the U. 8. Geological 

 Harvey, requiring him and his assistants to devote the most of their 

 tiiuc to original work in connection with the Surve,>': This work will, 

 in a large degree, inure to the benetitof the Museum colJections, as the 

 material studied contains numy new types and large numbers of species
