Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to the Cambridge University Press Asks for pulls of the portrait of Prof. [John Newport] Langley as found in the March No. of the Journal of Physiology, so it can be used for the Royal Society's Obituary Notice for him. Asks if the portrait is in collotype or photogravure, as the plate of the latter is more likely to survive. 12 November 1926
