Letter from R G [Reginald Graham] Durrant, The College, Marlborough, to [Joseph] Larmor Durrant has cut down the manuscript pages to 30. He comments that he 'cannot think that so many agreements between observation and theory are the result of chance'. He is finding the work very difficult, but feels lucky to have witnessed what 'must have been due to a combination of circumstances unlikely to occur together'. 10 May 1907
