PRIZES. 
The Keith Prize for 1893-5 was presented to Dr Cargill 
G. Knott, for his papers on the Strains produced by Magnetism 
in Iron and in Nickel, which have appeared in the Transactions 
and Proceedings of the Society. 
The President, on presenting the Prize, said : — 
The various results of Dr Knott’s investigations on Magnetic 
Strains have been communicated from time to time to the Royal 
Society of Edinburgh, and are embodied in five papers, four of 
which are published in the Transactions. The fifth is now passing 
through the press. A sixth will be communicated to the Royal 
Society this evening. 
I. On Superposed Magnetisms in Iron and Nickel. Read 
July 2, 1883; vol. xxxii. pp. 193-203. 
In this paper the Wiedemann effect — that is, the twist produced 
in a longitudinally magnetised wire when a current is passed along 
it — is studied. The effect in nickel is shown to be opposite to that 
in iron.
