Letter from Edward Albert Sharpey Schafer, Department of Physiology, University New Buildings, Edinburgh, to Sir Charles Scott Sherrington, President, the Royal Society He hopes that there is no doubt about the reappointment of Dr Lancelot Hogben to the Mackinnon Studentship. He has had it for two years and the regulations state it may be held for up to five years in exceptional cases. Hogben is an exceptional case. He is married, with children, and requires additional income to give time to research. The work he has done so far is 'considerable and important'. 7 May 1924
