Copy letter from Robert William Frederick Harrison, to Professor Almroth Edward Wright Harrison reports that he has received authority to proceed with the publication of Wright's paper, 'Further observations on the role of blood fluids in connexion with phagocytosis' in Proceedings of the Royal Society. He enquires as whether Wright considers the reproduction of the paper's illustrations in colour as essential or has other strong views on the matter, noting the saving that could be achieved by a shaded or 'other distinguished' drawing. 20 January 1904
