Copy letter from Robert William Frederick Harrison to Captain A D Fraser RAMC 'I have to acknowledge the receipt of your letter of June 29 returning the typed copies of your Sleeping Sickness reports, together with page 7 of the original MS. I understood from Sir John Bradford that we had these copies made for your benefit, because you wished to keep a copy, while we retained the original for publication. If I am right in this impression I will return you the typed copies. With reference to the paper "Various Experiments", I only had instructions to have copies made of the five papers already sent to you; but if you wish to have on of this paper also I have no doubt I can obtain authority to have it done for you.' 3 July 1911
