IX. — students and Visitors. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 682. 



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.
