Copy letter from Robert William Frederick Harrison, to Sir William Leishman, Fellow of the Royal Society, Royal Army Medical College, Grosvenor Road, S.W. Three months ago Sir David Bruce wrote asking to be sent some outline pencil drawings of trypanosomes relating to the Uganda work, which he said positively he deposited at the Royal Society before he left England. No trace can be found of them, nor is there any recollection of him leaving such drawings. Bruce was informed, and he has sent a cablegram saying 'Try College', presumably the R A M College. Harrison would be greatly obliged if Leishman could cause a search to be made. 29 July 1912
