Letter from [Alan Archibald Campbell] Swinton, The Athenaeum, Pall Mall, S. W., to the Editor of The Sunday Times Expresses indignation at the unworthy and unwarranted attack upon the revered President of the British Association for the Advancement of Science, Sir Arthur Keith, contained in the Times issue of 13 May, written by Mr. Alfred Moyes, who appears to be ignorant of modern science that he thinks that the new theories of the constitution of matter, with their protons and revolving electrons, because they cannot be seen in the microscope are not the results of experimented observation made by the use of the human senses. 14 May 1928
