Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to Professor [Karl] Pearson, FRS 'Dear Sir, In reply to your enquiry of the 15th instant I have looked up your references in the "Revue Scientifique 1874" and I find that the passages to which you refer are still marked with a small cross; they appear in parts 14 and 15 for that year.' 19 September 1922
