Referee's report by Herbert William Richmond, on a paper 'The design of repeating patterns' by Percy Alexander MacMahon and W P D MacMahon Sectional Committee: Mathematics Recommended for publication in the 'Proceedings of the Royal Society of London', however if this is 'Part I' as indicated, the full paper might be too long. Suggests omitting a few of the drawings. Refers to work of Arthur Moritz Schoenflies. From knowledge of the author's previous work, this new series will be well developed and thorough. [Published in the 'Proceedings of the Royal Society of London' A, 1922] Endorsed on verso as received 17 November 1921. [November 1921]
