Department of Mineralogy. 



The specimens added to the Collection, during the year 1875, have been 862 in 

 number, and they have been registered, labelled, and incorporated in the Collection. 



The portion of the collection reserved in drawers continues to occupy any spare time 

 of the Department, and the cases which contain the liydrated carbonates. Olivine, and the 

 other basic Silicates, and the Silicates belonging to the large class of minerals of Horn- 

 blendic and Augitic type have been carefully sifted of duplicate specimens, localities 

 attached wherever research could determine them, and the whole labelled and arranged 

 in clean trays. 



The MS. indices to the several volumes of the General Catalogue, have been completed 

 during the past year, and a general index comprising all these is now in progress. 



But the chief occupation of the Department has been the systematic elaboration of the 

 materials for the publication of a Scientific Catalogue of t!ie whole collection, witli. crystal- 

 lographic descriptions and chemical analyses of those specimens the composition of which 

 it*is desirable more accurately to determine.
