Copy letter from Robert William Frederick Harrison, to the Assistant Secretary, Marine Department, Board of Trade, 7 Whitehall Gardens, S.W. With reference to the Assistant Secretary's letter of the 13th, the Board of Trade must have been misinformed on the subject of the investigation by the Royal Society into the causes and treatment of scurvy, as no such investigation has up to the present been undertaken by the Society. So far as Harrison knows the subject has not been taken up by any other learned Society in London. 17 October 1899
