Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to Professor Karl Pearson, FRS In reply to Professor Karl Pearson's letter, informs him that the volume of the Connaissance des Temps for 1830 [written here accidentally as '1930'] cannot be found in the Royal Society Library. Does not think that the book was ever returned here, and suggests a search of the College Library. 2 August 1929
