INSTRUCTIONS TO AUTHORS. 
The ‘copy ’ should be written on large sheets of paper, on one side only, 
and the pages should be clearly numbered. The MS. must be easily legible, 
preferably typewritten, and must be absolutely in its final form for printing ; 
so that corrections in proof shall be as few as possible, and shall not cause 
overrunning in the lines or pages of the proof. All tables of contents, 
references to plates, or illustrations in the text, etc., must be in their proper 
places, with the page numbers left blank ; and spaces must be indicated 
for the insertion of illustrations that are to appear in the text. 
Illustrations. — All illustrations must be drawn in a form im- 
mediately suitable for reproduction ; and such illustrations as can be 
reproduced by photographic processes should, so far as possible, be 
preferred. Drawings to be reproduced as line blocks should be made with 
Indian ink (deadened with yellow if of bluish tone), preferably on fine 
white bristol board, free from folds or creases ; smooth, clean lines, or 
sharp dots, but no washes or colours, should be used. If the drawings are 
done on a large scale, to be afterwards reduced by photography, any 
lettering or other legend must be on a corresponding scale. 
If an author finds it inconvenient to furnish the drawings according to 
these regulations, the Society will have the figures re-drawn and the letter- 
ing entered at his expense ; but this will cause delay. 
When the illustrations are to form plates, a scheme for the arrangement 
of the figures (in quarto plates for the Transactions, in octavo for the 
Proceedings) must be given, and numbering and lettering indicated. 
Proofs. — In general, a first proof and a revise of each paper will be 
sent to the author, whose address should be indicated on the MS. If 
further proofs are required, owing to corrections or alterations for which 
the printer is not responsible, the expense of such proofs and corrections 
will be charged against the author. 
All proofs must, if possible, be returned within one week, addressed to 
The Secretary , Royal Society , 22-24 George Street , Edinburgh , and not to 
the printer. To prevent delay, authors residing abroad should appoint 
some one residing in this country to correct their proofs. 
The author receives fifty of the reprints free, and may have any 
reasonable number of additional copies at a fixed scale of prices w T hich 
will be furnished by the printer, who will charge him with the cost. To 
prevent disappointment, especially if the paper contains plates, the author 
should, immediately after receiving his first proof, notify to the printer 
the number of additional copies required. 
Index Slips. — In order to facilitate the compilation of Subject 
Indices, and to secure that due attention to the important points in a 
paper shall be given in General Catalogues of Scientific Literature and 
in Abstracts by Periodicals, every author is requested to return to the 
Secretary, along with his final proof, a brief index (on the model given 
below), of the points in it which he considers new or important. These 
indices will be edited by the Secretary, and incorporated in Separate Index 
Slips, to be issued with each part of the Proceedings and Transactions.
