values obtained by the British analysts, -which are added for comparison ; 

 the American results are subject to slight revision at Chicago, and should 

 any alterations be made these will be inserted before this report is finally 

 published. 



I. — Mean Results of the Analyses hy the American Committee. 



II. — Mean Results of the Analyses hy the British Committee. 



A report has also been forwarded by Professor Akerman on behalf of 

 the Swedish Committee, but as the results iaclnded in this report have 

 not yet been revised, they are intended for the guidance of the other com- 

 mittees, and not for publication. It may, however, be stated that the 

 agreement between the Swedish and British reports is quite as good as 

 that between the two above given. 



Standard 5, the preparation of which was mentioned in the previous 

 report of this Committee, has been hermetically sealed in glass tubes, like 

 Standards 1, 2, 3, and 4. It was thought well not to proceed with the 

 analysis of this standard until an opportunity had been aflPorded of com- 

 paring the results obtained by the various committees on the analyses of 

 the standards already under examination. Otherwise, after the work of 

 the British analysts was completed, questions as to methods of analysis 

 or other points of detail might have arisen, without a convenient oppor- 

 tunity being afforded for their investigation. 



Now that reports from three out of the five International Committees 

 are at hand for comparison, they will be considered by this Committee,, 

 and the analysis of the remaining standard completed. 



On Solution. — Report of the GomTnittee, consisting of Professor 

 W. A. TiLDEN (Chairman), Dr. W. W. J. NicoL {Secretary)^ 

 and Professor W. Kamsay. 



The Committee have continued their work on the lines laid down in the 

 report of last year, but the progress made and the results obtained are 

 not such as to warrant the publication of any general conclusions at 

 present. The Committee intend to continue their investigations, and 

 therefore desire reappointment without a grant.
