Memorandum by Andrew Russell Forsyth, on a paper 'On simultaneous partial differential equations' by Alfred Cardew Dixon It was agreed by the Council that only the portions relating to bidifferentials would be published, if the referees found the modified paper satisfactory. The author has requested that the Mathematics Committee reconsider the recommendation to omit the portions on multidifferentials. Has drafted a minute for the Committee to sign.
