Letter from George Hemmen, Royal Society to E J H Corner, Botany School, Cambridge Letter to keep Corner up to date with the expedition preparations. Hemmen writes that equipment has left London for North Borneo and encloses lists for Corner's information. Asks that Corner mark on the list which packages should be sent by air or landrover to Ranau. Hemmen makes own suggestions with regard to this and adds that they have yet to consider equipment being sent from Singapore. Finally gives Corner estimates of the costs of shipping so far. 26 April 1961
