Meeting of the Committee. 



The Committee met once during the year, on October 29. The annual 

 grant of £100 from the Caird Fund was allocated to the University 

 Observatory, Oxford, for yvovk on the International Seismological Summary. 

 Expenditure on various objects from the Gray-Milne Fund was author- 

 ised. Dr. E. C. Bullard gave a short account of the methods adopted in 

 America in the application of seismological methods to the investigation of 

 the thickness of the strata overlying the continental shelf. In view of the 

 fact that research on these lines was likely to be undertaken with the support 

 of the Royal Society, it was decided that no action on the part of the British 

 Association was necessary. Dr. Dollar gave the Committee an account of 

 the British Earthquake Inquiry, which he was organising, and it was 

 decided to give some financial support to the organisation. 



The Gray-Milne Fund. 



The accounts for the year are reproduced below. The income of the 

 fund has again improved owing to an increase in the dividend paid by the 

 Canadian Pacific Railway. Expenditure on the Milne Library includes 

 the purchase of Dr. Davison's book. Great Earthquakes.
