NOTICE TO AUTHORS AND COMMUNICATORS. 



The Council have had under consideration the rapid increase of the Society's 

 expenditure on p' ' '"'cations. In view of the necessity for economy, authors of papers 

 are urgently requested to see that their communications are put in as concise a form as 

 possible. Delay in decisions regarding publication, as well as subsequent trouble to 

 authors, is often caused by diffuseness or prolixity. MSS. must be type-written or at 

 least written in a legible hand, and properly prepared as copy for press. Type-written 

 transcript should in aH cases be carefully revised by the author before being presented. 

 It is desirable that authors should retain copies of their MSS. for reference. 



Authors are requested to refer to a Memorandum on Mathematical Notation 

 published in thdse ' Proceedings," 1 909, Series A, vol. 82, p. 1 4, and to adhere to the 

 suggestions therein contained, so far as possible. 



Authors are further requested to send in all drawings, diagrams or other illustrations 

 in a state suitable for direct photographic reproduction. They should be drawn on 

 a large scale in Indian ink on a smooth white surface, with temporary lettering in 

 pencil. Great care should be exercised in selecting only those that are essential. 

 Where the illustrations are numerous, much time would be saved if the authors would 

 indicate in advance those which, if a reduction of their number is found to be required, 

 might be omitted with least inconvenience. 



" It shall be the duty of each Fellow or Foreign Member to satisfy himself that any letter, report or 

 other paper which he may communicate, is suitable to be read before the Society." — Statute VI, Cap. xii.
