Copy letter from Joseph Larmor, to Professor Harold Baily Dixon, Fellow of the Royal Society 'Dear Professor Dixon, May 11th is a biological day. We can put your paper down, but it must be at the end, as the others have priority and come together as homogenous. Perhaps you prefer some other day. Believe me, Very truly yours, J. Larmor Sec. R. S. [Secretary, Royal Society]'. 14 April 1905
