a No census of collection taken. 



b The actual increase in the collections during the year 1889-'90 is much greater than appears from 

 a comparison of the totals for 1889 and for 1890. This is explained by the apparent absonceof any 

 increase in the Department of Lithology and Metallurgy, the total for 1890 ill both of these departments 

 combined showing a decrease of 46,314 specimens, owing to the rejection of worthless material. 



c Only a small portion of the collection represented by this number was received during the year 

 1889-90. 



d This relates only to specimens received through the Museum, and does not include material added 

 to the National Herbarium, through the Department of Agriculture. 



e Collections combined in October, 1889, under the Department of Geology. Tho apparent decrease 

 of more than 50 per cent, of the estimated total for 1889is accounted foi (1) by the rejection of several 

 thousands of specimens from the collection, and (2) by the fact that no estimate of the ones in the 

 reserveand duplicate series is included. Of tho total numbei for 1890 about 10,000 specimens consist 

 chiefly of petrographical material, stored away for study and comparison in the drawers of table cases. 



/ Transferred to National Zoological Park.
