[Annual Reports. 
Mineralogy. 
Mr. Crosby’s time has been about equally spent in the collections 
of Mineralogy and Geology, and in both departments he has been 
assisted by Miss Carter. In the Mineralogical department the 
sjiecimens catalogued by Mr. Bouve during the previous year 
have been labelled, mounted, and permanently arranged on the 
shelves. 
The Synoptical Collection of Minerals has been greatly extended 
and now occupies both of the floor cases. The capacity of the 
w^all-cases on the main floor has been increased by the addition 
of new shelves, and by the construction of a platform or step 
designed to bring the upper shelves within reach of the eye, 
The accessions for the year consist of about 100 mineral spec- 
imens, a set of ten mica models of crystals and 250 plastic models 
showing the forms of the more important species. 
Geology. 
In the Geological department sixty new specimens have been 
catalogued, and these, together with about 500 specimens cata- 
logued during the previous year, have been labelled and placed on 
exhibition. 
The blew England collection of rocks has been arranged as 
well as the limited case room will admit, but it is not yet cata- 
logued or mounted. It now includes about 1500 specimens; and 
all the geological collections taken together amount to 5000 speci- 
mens. About 1000 new specimens have been received during the 
year, including 125 specimens of the typical rocks of blew 
Brunswick, from Prof. L. W. Bailey; 130 specimens from Ver- 
mont and blew Hampshire collected by Dr. H. A. Cutting; 160 
specimens from Vermont and New York, received from the 
University of Vermont; 75 specimens collected on the coast of

400 specimens collected by Mr. Crosby in different parts of New 
England and New York.
