Copy letter from Robert William Frederick Harrison, Assistant Secretary of the Royal Society; to Professor B [Birbal] Sahni, FRS; The University Benares, India Asks if Professor Sahni is prepared to revise his paper 'The structure and affinities of Acmopyle Pancheri, Pilger'' which has been under consideration in light of the following criticism; 'The author does not clearly and briefly state the alternatives and then after argument his own conclusions. The consequence is a foggy effect. This is especially exemplified by sheets 85-94 on ovuliferous conifers. I think this section might easily be amended as well as other parts of the technical discussion, so as to secure greater clearness combined with conciseness.' 24 July 1919
