Copy letter from Robert William Frederick Harrison, to Professor Arthur Schuster, Fellow of the Royal Society, Chairman of the Physics and Chemistry Sectional Committee The five papers by Professor H E Armstrong and others on 'Studies of the processes operative in solutions' were referred by Professor J Walker, whose report is favourable to publication. The Physical Secretary however thinks that it would be advisable to have another report on the papers and suggests that they be sent to Sir W Tilden. Asks Schuster to say whether he concurs. 12 October 1912
