whole collection may be said to consist of about 3,200 speci- 

 mens all arranged and labelled. 



Diu-ing the past year the cast of the Megatherium pre- 

 sented to the Society by the late Joshua Bates, Esq., of 

 London, has been mounted. This was put up in the centre 

 of the eastern part of the main hall by Mr. Sceva, with 

 artistic skill, under the superintendence of Prof Jeffries Wy- 

 mau and Dr. J. C. White, and it is believed to present a pos- 

 ture in accordance with the character and habits of the 

 animal. 



The additions during the past year have been considerable, 

 amounting in all to 825 specimens. The most important are 

 a series of casts of large animals obtained from Prof H. A. 

 Ward in exchange, and a collection of fragments of fossil 

 Mammals from the Andes, collected and presented by Dr. C. 

 F. AYinslow. The other donors are the Smithsonian Insti- 

 tution, Prof H. A. Ward, Drs. H. I. Bowditch, S. A. Green, 

 T. B. Hitchcock, C. T. Jackson and S. Kneeland ; and Messrs. 

 E. A. Brigham, W. H. Dall, S. Rice, J. T. Rothrock, H. B. 

 Stanwood and S. H. Scudder. 



The north-eastern room is devoted to the Mineralogical 

 collection which is arranged according to Dana's system. 

 There are about 1,500 specimens on exhibition. A great 

 deal of labor has been spent upon the collection by the acting 

 curator, Mr. Bouve. Within the last three months the 

 whole collection has been entirely rearranged, and every 

 specimen, with few exceptions, has been washed and will 

 soon be labelled. 268 specimens were added during the past 

 year by Drs. A. A. Gould, C. T. Jackson and B. S. Shaw, 

 Rev. E. B. Eddy, Messrs. W. H. Dall, W. T. Eustis, S. H. 

 Scudder, E. L. Sturtevant, and a company of gentlemen. 



The space allotted to the collection of Comparative Ana- 

 tomy and Mammalia, comprises the entire lower floor of the 

 western extremity of the main hall, opposite the Palasonto- 

 logical collections, with the adjoining apartments. The cases 

 in the hall are entirely devoted to the reception of mounted
