DEPARTMENT OF MINERALOGY. 165 



copper glance, and cinnabar) as far as nagyagite, and for 

 the haloid division from sylvite to iodyrite inclusive, while 

 many of the specimens exhibited in the case-tops have 

 been rearranged on trays that have been repolished and lined 

 with fresh wool. At the same time, old specimens hitherto 

 bearing numbers referring only to special catalogues have 

 been entered in the General Register, and permanent labels 

 giving all available information have been written for each 

 specimen. Further, a slip-list has been prepared of all the 

 specimens in the crystal-collection. 



The reserve collections of galena, sartorite, jamesonite, 

 miargyrite, calaverite, tetrahedrite, salt, etc., have been 

 extended into drawers previously occupied by specimens of 

 British rocks which have now been transferred to cases in 

 the Pavilion. 



An exhibit of models of the " Cullinan " and other famous 

 diamonds has been placed in the Central Hall. 



The work of fitting the doors of the cases in the Gallery 

 with link-plates has been finished. 



Seventy-eight boxes of mineral-specimens have been 

 received, unpacked and examined ; seventy-nine boxes have 

 been packed and despatched. 



One hundred and sixty-two thin slices of rocks have been 

 prepared. 



Departmental Library. 



To the Departmental Library have been added continua- 

 tions of 30 periodicals (in 403 parts), 48 volumes of separate 

 works, 88 pamphlets, 21 parts of works, 6 maps, 30 plates 

 of photographs, and 51 mining and survey reports ; of these, 

 9 periodicals (in 130 parts), 23 volumes of separate works, 

 84 pamphlets, and all the mining and survey reports were 

 acquired by presentation or transfer. All of them, including 

 919 plates, have been registered and stamped. 



Three new book-cases with 327 feet of shelf-space have 

 been fitted up in the S.E. Basement corridor, and 841 volumes 

 have been removed to the shelves. 



Students. 



The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 855. 



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.
