 by the " Albatross," and kindly sent me for study by Colonel 

 Macdonald, the U. S. Fish Commissioner. 



The accessions to the Library are more numerous than in the 

 previous year, and it now numbers more than twenty thousand 

 volumes, exclusive of the Whitney Library. This growth is 

 principally due to the increase of our exchange list. 



This is the first year in which the Museum has practically 

 lived within its income, while fully sustaining its usual work not 

 only in instruction, but also in the increase of its collections and 

 of its Library ; its publications have equalled in importance those 

 of former years, and the investigations carried on within its walls 

 have not been in the least curtailed. Still, until the advances 

 made to the Museum by the Corporation for the Geological Sec- 

 tion and for the purchase of fossils have been repaid, we cannot 

 be expected to show as great activity as if our resources were 

 unencumbered. We need about thirty thousand dollars to place 

 the Museum on a completely independent footing again.
