DEPAETMENT OF MINERALOGY. 165 



Historical Notes ; many specimens have been labelled with 

 the information found respecting them. 



The lists of mineral sections, crystal models, instruments, 

 and apparatus in general, have been brought up to date. 



The improved form of three-circle goniometer has been 

 put into adjustment, and alterations found necessary in the 

 optical arrangements have been made. 



Experiments have been made on the phosphorescent eiiects 

 of radium, and illustrations of these properties have been 

 arranged in the Central Hall of the Museum. 



A series of fulgurites has been mounted in two special 

 cases and exhibited in the Pavilion. 



The collections of barytes and hornsilvers have been 

 rearranged. 



Numerous specimens sent, or brought to the Museum by 

 visitors, have been examined and named. 



The preparation of a copy of the Eegister of the specimens 

 in the collection has been in progress. 



Assistance has been given in the revision of the proofs of 

 the Catalogue of the Museum Library. 



Seventy boxes of mineral specimens have been received, 

 unpacked, and examined ; seventy boxes have been packed 

 and despatched. 



Departmental Library. 

 To the Departmental Library have been added continua- 

 tions of 27 periodicals (in 451 parts), 38 volumes of separate 

 works, and 97 pamphlets and parts of works ; of these, 9 

 periodicals (in 127 parts), 11 volumes of separate works, and 

 69 pamphlets and parts of works, were acquired by presenta- 

 tion or transfer. All of them, including 733 p]ates, have been 

 registered and stamped. 



Students. 

 ■ The number of visits recorded as made to the Department 

 for the purposes of consultation or study is 1,541. 



The Gallery is no longer reserved on particular days 

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

 have 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 

 thus become difficult to distinguish, for statistical purposes, 

 " Students" of minerals from ordinary " Visitors," and stress 

 can no longer be laid on the distinction. 



Demonstration. 

 A demonstration on the meteorites was given by Mr. 

 G. T. Prior on Saturday, March 28, 1903, to 46 members of the 

 Geologists' Association.
