Letter from [Henry George] Lyons, 3 Durham Place, Chelsea, S.W, to Dr [Arthur] Schuster, [Royal Society] Informs that Robert Harrison has written to him informing him of the President's request for him to get the Royal Society porter's exemption regularised. States that after having looked into the matter and realising that things have gone so far, it would be extremely difficult to do anything at all, detailing his findings. 23 October 1916
