172 ACCOUNTS, ETC. OF THE BRITISH MUSEUM. 



volumes of separate works, GO pamphlets and parts of works, 

 and all the mining and survey reports were acquired by pre- 

 sentation or transfer. All of them, including 730 plates, 

 have been collated, registered and stamped. 



Students. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 994. 



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 informa- 

 tion 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. 



Demonstrations. 

 A demonstration on Precious Stones and Meteorites was 

 given by Dr. Prior to twenty-five members of the London 

 Pupil Teachers' Association on November 25. 



Exchanges. 



Exchanges of specimens have been made with Dr. H. A. 

 Ward, of Chicago, and Dr. F. Krantz, of Bonn.

388 minerals, 681 rocks, and 14 meteorites. All of them 

 have been registered, numbered, labelled, and incorporated 

 with the Collection.
