Letter from G E Hemmen, Royal Society to G P Askew, Wye College, Kent States that he did not reply to Askew's letter 13 April as he has expected to see him in Londonat a meeting with Corner and Stainton. Asks if he can let him know when he will be coming up [to London]. Does not have a detailed map of the area South of Kinabalu, but thinks that aerial photographs of the area may meet Askew's requirements. 25 April 1961
