170 ACCOUNTS, ETC., OF THE BRITISH MUSEUM. 



27 pamphlets, 103 mining and survey reports, and 11 periodi- 

 cals (in 127 volumes and parts), were received by presentation 

 or transfer. All of them, including 1,608 plates, have been 

 registered and staoiped. 



Students. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 838. 



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.
