246 REPORT OF NATIONAL MUSEUM, 1891. 



Tbe catalogue iuimb(n's taken up duriDg tlie year were from 23843 to 

 24058, botli inclusive. 



I^otices of the publications by the members of this department dur- 

 ing' the year will be found in the Bibliography (Section iv). 



It is very diflicult to handle the large amount of material coming in 

 fi'om the Geological Survey and other sources, owing to the limited 

 laboratory i-oom. Over fifty i)acki ng boxes of material, collected l»y the 

 Geological Survey, have been put in storage on account of the neces- 

 sity of obtaining room for collections that needed immediate study. 

 This was in order that reports might be made to the geologists of the 

 Geological Survey who desired to use the information in connection 

 with their field work. It will not be possible to make a detailed report 

 on the collections or to separate the duplicates until much greater facili- 

 ties shall be had for handling them.
