6^ SdLlR RADIATION. 45 



grid, provided that the distance is not too small. It is intended in the 

 bourse of the ensuing year to continue the absolute measurements, and to 

 test the performance of the automatic recorders under a greater variety of 

 conditions, for which Mr. Wilson, of Daramona Observatory, has promised 

 his assistance ; but enough has already been accomplished to show that the 

 apparatus affords a very promising and practical method of recording and 

 reducing to absolute measure the vertical intensity of radiation at any 

 point of the earth's surface. 



Vniformitij of Size of Pages of Transactions. — lieport of the Com- 

 mitlce, consisting of Professor S. P. Thompson (Chairman), Mr. 

 J. Swinburne (Secretary), Professor G. H. Bryan, Mr. C. V. 

 Burton, Mr. K. T. Glazebrook, Professor A. W. Ruckek, and 

 Dr. G. Johnstone Stoney, appointed to confer with British andj 

 Foreign Societies, publishing Mathematical and. Physical Papers, as 

 to the Besirahility of securing Uniformity in the Size of the Pages of 

 their Transactions and Proceedings. (Drawn up by J. Swinburne.) 



A LARGE number of journals were measured to find what dimensions it 

 would be best to choose as standards. An account of this work was 

 published in the Report for 189-5, p. 77. 



Since that date a large volume of correspondence has been carried on 

 with the English and foreign scientific societies. 



In most cases the societies' publications come within the limits speci- 

 fied in the first report. 



In some of the cases the societies agreed to alter their publications so 

 as to come within the standard limits. 



In a few cases the societies prefer to continue the use of abnormal 

 dimensions rather than alter their publications, especially when the pub- 

 lication has been going on for many years. 



The importance of beginning a paper on the right-hand page is 

 generally realised, but there are difficulties in carrying it out. In spite 

 of this, a few of the societies are endeavouring to arrange that all 

 important papers shall begin on the right-hand page. 



The Committee do not ask for reappointment. 



Determining Magnetic Force on Board Ship. — Ileport of the Committee, 

 consisting of Professor A. W. Pucker (Chairman), Dr. C. H, 

 Lees (Secretary), Lord Kelvin, Professor A. Schuster, Captain 

 Creak, Professor W. Stroud, Mr. C. Vernon Boys, and Mr, 

 W. Watson, appointed to consider the most suitable Method of 

 determining the Components of the Magnetic Force on Board Ship. 



An instrument which embodies the ideas of Captain Creak, mentioned in 

 last year's Report, has been constructed. Although specially designed for 

 observations on board ship, it will probably from its strength of construc- 

 tion be found suitable for travelling parties. 



The Committee apply for reappointment, with the unexpended grant 

 of 10^. made last year.
