Copy letter from Robert William Frederick Harrison to Professor E [Edward] A [Alfred] Minchin Harrison has been requested by the Tropical Diseases Committee to ask whether Minchin would be willing to investigate some specimens of the blood of birds, reptiles, &c which Sir David Bruce has sent from Uganda. The investigations would be in Minchin's hands on the understanding that he undertook to furnish the Committee with a report on the specimens to be published in the Reports of the Sleeping Sickness Commission, and that the accompanying drawings should be returned. 22 July 1909
