CONDITION OF THE COLLECTIONS. 



Mr. Bouve, as Chairman of the Committee on Mineralogy, 

 reports that the collection remains in its former good condi- 

 tion. It has received some accessions during the year by the 

 purchase of some desirable specimens from the Jackson Col- 

 lection. It now consists of 3,230 trays and single specimens, 

 of which 347 are in the New England collection. These 

 are largely selected specimens, many of them of exceptional 

 excellence and value. 



The Geological Collection has been nearly completed by 

 the same gentleman, and will be opened to the public within 

 a short time. A full account of the mode of arrangement 

 will therefore be deferred until the next Annual Report. 



Mr. Crosby's time has been, of course, largely taken up by 

 the preparation of the Geological Map, above described, and 

 this has interrupted the progress of the mounting of the 

 Paleontological Collection, which was going on under his 

 direction. Miss Carter has, however, finished the fossils of 

 the Tertiary formation, in the European Collection, and Miss 

 Washburn a considerable number of the American fossils; 

 and this work will probably be speedily resumed. 



The work on the Botanical Collection, under the charge of 

 Mr. Cummings, has been going on steadily, although this gen- 

 tleman's increased public duties have prevented him from 

 giving us so much of his own time as in former years. The 

 New England Collection has been completed, poisoned, and 

 catalogued by Miss Carter, and is now ready for exhibition. 

 It contains nearly every species found within the borders of 

 the New England States and in most cases, two specimens of 

 a species. There are 1984 species and 3227 specimens. The 

 " Lowell Collection " is being poisoned and catalogued, one- 

 third of it being already finished. Nearly one-half of the
