Copy letter from Robert William Frederick Harrison, to [William Bate] Hardy, Fellow of the Royal Society, Chairman of the Physiology Sectional Committee Sir William Leishman has reported in favour of the paper by Blacklock and Yorke on 'Trypansomes causing dourine', communicated by Sir Ronald Ross. He says that although it is not of great importance, it should be published as it records interesting observations of a subject which is much debated at the moment. Asks the Chairman to minute instructions. 12 July 1913
