Copy letter from Robert William Frederick Harrison to Professor F [Frederick] W [William] Gamble FRS 'Replying to your letter of the 8th instant about the Sleeping Sickness Reports, these Reports have been to such a large extent made the subject of presentations that I fell I should be quite justified in sending you those numbers, of which a sufficient stock remains, without charge, and Nos 2, 4, and 5 of those you mention would fall in to this category. We regard, however, to Nos 1 and 3, so very few copies are left that I should not feel myself justified in parting with them except at the published prices, which are 7/6 and 6/- respectively. If this mode of meeting the situation commends itself to you I will act upon it on hearing from you.' 13 June 1911
