158 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



Departmental Library. 



To the Departmental Library have been added continua- 

 tions of 31 periodicals (in 438 parts), 53 volumes of separate 

 works, 43 pamphlets, 16 parts of works, 32 mining and survey 

 reports and one map ; of these, 8 periodicals (in 124 parts), 

 4 volumes and 6 parts of separate works, 33 pamphlets, and 

 all the mining and survey reports, were acquired by presenta- 

 tion or transfer. All of them, including 601 plates, have been 

 registered and stamped. 



360 volumes have been transferred to the new cases in the 

 basement corridor, and arranged. 



All works of a topographical character have been placed in 

 one main group and arranged in geographical order. 



Students. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 987. 



The Gallery being no longer reserved on particular days of 

 the week for use by students, and study-series having been 

 so arranged as to be directly accessible to the public, and so 

 labelled as to render reference to the staff for information 

 thereon almost completely unnecessary, it has become difficult 

 to distinguish, for statistical purposes, " Students " of minerals 

 from ordinary " Visitors," and stress can no longer be laid 

 on the distinction. 



Exchanges. 

 Exchanges of specimens have been made with Dr. Victor 

 Patzelt of Briix, Bohemia ; the Mineralogical Institute of the 

 University of Christiania, through Prof. W. C. Brogger ; the 

 Museum d'Histoire Naturelle of Paris, through Prof. A. Lacroix ; 

 and with Sir William Crookes, f.r.s.
