In regard to the accessions during the past year, a list of 

 which is given below, the only one of much importance is the 

 Musci Exsiccati Boreali-Americani of W. S. Sullivant and 

 Leo Lesquereux, containing three hundred and fifty-five spe- 

 cies, and the Lichenes Americanse Septentrionales, curante E. 

 Tuckerman, fascicule 1-6, containing over one hundred spe- 

 cies, besides numerous other species from different localities of 

 both Mosses and Lichens, presented by our fonner Curator 

 C. J. Sprague, Esq., to whom the Herbarium already owed 

 so much in the very valuable series of Fungi which it now 

 possesses. These accessions have made the Cryptogamic 

 collection equal in value with the rest of the Herbarium, and 

 give a fair illustration of those plants which are found in the 

 United States. 



Specimens have also been presented by Drs. J. S. Bemis, 

 C. Pickering, C. F. Winslow, A. S. Packard, Jr., S. Knee- 

 land, Jr., and Messrs. Gunning, E. R. Mayo, H. M. Mclntire, 

 William Nelson, and S. Wells, Jr. 



The Curator of Mineralogy reports that he has been en- 

 gaged during all the time that he could devote to this de- 

 partment, in cleaning and in placing upon the shelves, such 

 specimens as were considered worth adding to the collection. 

 The whole number of specimens belonging to the Society, 

 now on exhibition, is about two thousand, and there are 

 besides a large number that will be serviceable for exchange. 



Of the whole number, a considerable portion have become 

 the property of the Society through the liberality of Dr. 

 Charles T. Jackson, and such portion would have been much 

 greater than it is, if it had not been for the destruction of a 

 large number of specimens in the damp cellar of our former 

 building in Mason Street, Avhere they were unfortunately 

 stored for many years. 



Dr. Jackson has continued to manifest his interest by pre- 

 senting from time to time during the year j^ast, valuable min- 

 erals brought by him from various localities, and the collec- 

 tion is also indebted to the Agassiz Natural History 

 Society, to Dr. W. H. Dale, Dr. Henry Bryant, Dr. A. S. 

 Packard, Jr., G. P. Huntington, Prof Jeffries Wyman and 

 others for interesting si^ecimens.
