NOTICE TO AUTHORS AND COMMUNICATORS. | 3s 
The Council have had under consideration the rapid increase of the Society's bee 
expenditure on publications. 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-wnitten 
transcript should in all 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 further requested to send in all drawings, diagrams or other laeetene 
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 lettering adapted to a 
reduction in scale. 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. xu.
