2 Presidential Address 



Arts; and he devoted social and political 

 energy to the welfare of the multitude 

 of his fellows less fortunately situated

Through the untimely death of Sir 

 George Darwin the world has lost a 

 mathematical astronomer whose work 

 on the Tides and allied phenomena is a 

 monument of power and achievement. 

 So recently as our visit to S. Africa he

Within the last month I have heard of 

 the premature death of John Milne, who 

 was apparently at the height of his 

 energy and usefulness. His enthusiasm 

 and persevering work for Seismology has 

 resulted in an international organisation 

 centring round his personality. He has, 

 I am told, left 1000 to help continue 

 the work, and it behoves us to see that 

 no sinews of war shall be lacking to 

 assist survivors in organising and con- 

 tinuing the attack in this immensely 

 important field of combined and co- 

 operative research.
