The British Rainfall Organization. The Geographical Journal, 

 Vol. XXXVI, No. i, July 1910, p. 98. 



" An important development in the position of this organization 

 took place during June 1910. The valuable work of the organization 

 is quite unofficial, and has hitherto been carried on purely at the 

 personal responsibility firstly of its founder, Mr. J. G. Symonds, 

 and later of his successors, Mr. Sowerby Wallis and Dr. H. R. Mill, 

 under the latter of whom its activities have been extended and its 

 methods reorganized and improved. Feeling that the time had 

 come for placing the enterprise on a more permanent and secure 

 basis, Dr. Mill has, with great public spirit, made over the com- 

 plete rainfall records of the organization (which has now been in 

 existence just fifty years), together with the lease of the house in 

 Camden Square with which the work has been so long associated, 

 to a body of trustees all of them interested in rainfall observation, 

 and of a standing to ensure the efficient prosecution of the work 

 in the future. As a representative of the Royal Geographical 

 Society, Mr. D. W. Freshfield is included among the trustees. A 

 beginning has been made towards the collection of an endowment 

 fund, and it is hoped that this may in time attain sufficient pro- 

 portions to permit a further development of the important work 

 of the organization. "

 Atmosphere at Various Altitudes for Oxides of Nitrogen 

 and Ozone. Journal of the Chemical Society, Trans., London, 

 May 1910. 



These experiments were made systematically above Glossop 

 Moor in Derbyshire, during three or four months in summer, and 

 were supplemented by a number of tests on sea and mountain air 

 at various places in England. It was found that oxides of nitrogen 

 were always present in quantities which vary largely from time to 

 time, and that the amount of ozone was, in every case too small 

 to be detected in the experiments conducted at ground level and 

 at intermediate altitudes, that is up to 8000 feet. The amount 

 of ozone is less than i part in 4 ooo ooo ooo parts of air ; at very 

 high altitudes (ranging up to 10 miles), one part in three to nine 

 million parts of air by volume. The quantity of oxides of nitrogen 

 was shown to be less than this.
