With reference to your letter of May 13, the Royal Society has in stock a limited number of copies of the Report of the Committee on Colour Vision appointed by the Society in 1890, and I have please in forwarding twelve copies of the Report, for the purpose of supplying the members of the proposed Committee of Enquiry into Sight Tests in fords for those serving in the Mercantile Marine.
