Bihl'w(fi'aphij of Siiectroscoiyy. — Report of the Committee, consistinr/ of 

 Professor H. McLeod, Professor W. C. Eoberts-Austen, Mr. 

 H. G. Madan, and Mr. D. H, Nagel. 



The collection and verification of titles of papers on spectroscopy is lieing 

 continued, and a list is appended which brings the catalogue of spectro- 

 scopic literature up to the end of 1897. 



It is proposed to continue the work of the Committee up to the end 

 of the year 1899, after which date the commencement of the International 

 Catalogue of Scientitic Papers will render further procedure on the part 

 of the British Association unnecessary. 



The Committee are strongly of opinion that it is most desirable that 

 the separate instalments of the catalogue published at various dates in 

 the Reports of the Association should be (at the conclusion of the work) 

 collected, arranged as one continuous list of papers, and reprinted as a 

 whole. 



This would appear to be the only way of obtaining the ftll value of 

 the catalogue as a work of reference for those engaged on the subject of 

 spectroscopy. One of the members of the Committee is quite willing to 

 undertake the whole work of rearrangement of the matter and passing it 

 through the press. The only question is the expense of printing, which 

 will be certainly not less than 120^. Some of this might be met by 

 grants from the Association and from other scientific societies which 

 possess libraries ; and, to avoid actual loss, a charge might be made for 

 each copy of the catalogue. 



The matter need not be settled until next year, but in the meantime 

 the Committee hope that it will have the earnest consideration of the 

 Association. 



The Committee therefore ask to be reappointed.
