Lucy W. Say, Mr. Peterson, Mr. Haldcman, and Dr. Gould, of Boston. 

 Others have been derived from Dr. Mighels of Maine, Mr. Cassin, Dr. R. 

 Coates, Capt. Baker; and recently, a very largo accession lias been made 

 through exchange. 



Of Fossils, the donations this year have been fewer than usual. A most 

 interesting one, however, was that by General Irick, of Vincentown, N. J., of 

 the head of a fossil crocodile discovered in the vicinity of that place, and 

 which has formed the subject of a paper by Dr. Morton, who has regarded it 

 as new. Another donation of much value has recently been received from Dr. 

 Alfred T. King, of Westmoreland county, in this State, of fossils from the 

 carboniferous limestone of that region. 



The collection of Crania possessed by Dr. Morton, has been increased 

 during the present year by many additions of great value and interest. This 

 collection is now of such extent as to require, for its display, the entire range 

 of cases on the south flying-gallery, which have been resigned to Dr. Morton 

 for this purpose. It numbers about 600 crania, derived from all the races of 

 men, ancient and modern, and 640 crania of the lower orders of animals, 

 forming an aggregate believed to be greater than is possessed by any other indi- 

 vidual living. 



Additions to the Minerahgical cabinet have been made by Messrs. Ashmead, 

 Johnson, H. S. Stephens, Rice, Woodhouse, Kendall, Mease, Prof. Durbin, and 

 others. But the most important and valuable donation to this department, during 

 the present, or perhaps any previous year, has been that of an entire suite of 

 the minerals of Cumberland, Durham, Westmoreland, and other counties of 

 England, by our fellow-member, Dr. Thomas B. Wilson. This beautiful 

 collection was obtained by this gentleman during his recent visit to that 

 country, and was presented to the Academy immediately upon his return home. 

 It has greatly enriched our Cabinet, and the donor well deserves, and has re- 

 ceived the sincere thanks of the Society. 



In Botany, some donations of value have also been received. They are 

 chiefly from Dr. Englemann, of native Western plants ; from the late Dr. 

 Westley Johnson, of African plants; and from Mr. Jacob Snyder, jr., of this 

 city, of Alpine plants ; besides which, are smaller donations of fruits, seed 

 vessels, single specimens of plants, &c, from a number of contributors. 



The additions to the Library during the present year are as follows : 

 Folios, 4; Quartos, 26; Octavos, 16; Periodicals, (including Journals, Pro- 

 ceedings of Societies, &c.,) 35 ; Publications in pamphlet form, 36 ; and Maps 

 and Charts, 4. Of the whole number, 46 have been received from authors and 

 editors, 27 from members, and 50 from Correspondents, Societies, &c, and 

 also in exchange. The average is about equal to that of late years. 



One of the new ranges of cases erected this season, to which reference has 

 been made at the commencement of this report, was for the use of the Library. 

 The rapid increase of the latter has required this addition for some time past, 

 a large number of volumes having been crowded out of view, for want of room 

 in their appropriate places, and their existence in the library scarcely known to 

 the members. These have now been restored to their proper situations, and a
