Copy letter from Francis Alexander Towle, Assistant Secretary of the Royal Society; to Sir Sidney [Frederic] Harmer, FRS 'We would gladly do what you desire in the case of the volumes of the Encyclopedia Britannica, but infortunately we have neither the fourth, fifth nor sixth editions. We have only the 7th, 9th & 11th. I regret therefore we cannot assist in this case.' 26 January 1929
