158 ACCOUNTS, ETC. OF THE BRITISH MUSEUM. 



Departmental Library. 



To the Departmental Library have been added continua- 

 tions of 35 periodicals (in 625 parts), 53 volumes of separate 

 works, 84 pamphlets and parts of works, and 32 sheets of 

 maps : of these 59 pamphlets and 22 sheets of maps, 11 

 periodicals, and one separate work, were acquired by presen- 

 tation or transfer. 



All of them, including 1,159 plates, have been registered 

 and stamped. 



Students. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 1,264. 

 ' The Gallery is no longer reserved on particular days of the 

 week for the exclusive use of Students ; further, study-series 

 have been arranged in the public gallery where they are 

 directly accessible to the public, and have been so labelled 

 as to render all reference to the staff unnecessary : it has 

 thus become difficult to distinguish " Students " of minerals 

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

 on the distinction. 



Exchanges. 



Exchanges of specimens have been made with the Oxford 

 University Museum, and with Mr. Foote of Philadelphia. 



Acquisitions. 



1,075 specimens have been acquired during the year 1899,. 

 namely : — 551 minerals, 490 rocks, and 34 meteorites. These 

 have been registered, numbered, labelled, and incorporated 

 with the collection. 



The more important of them are as follows : —
