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, Mound, Edinburgh, and not to the printer. 
To prevent delay, authors residing abroad should appoint some one residing 
in this country to correct their proofs. 
4. Additions to a Paper after it has been finally handed in for 
publication, if accepted by the Council, will be treated and dated as 
separate communications, and may, or may not, be printed immediately 
after the original paper. 
5. Brief Abstracts of Transactions Papers will be published in 
the Proceedings, provided they are sent along with the original paper. 
6. Separate Issue of Reprints; Author’s Free and Additional 
Copies. — As soon as the final revise of a Transactions paper has been 
returned, or as soon as the sheet in which the last part of a Proceedings 
paper appears is ready for press, a certain number of separate copies or 
reprints, in covers bearing the title of the paper and the name of the 
author, are printed off and placed on sale. The date of such separate 
publication will be printed on each paper. 
The author receives fifty of these reprints free, and may have any 
reasonable number of additional copies at a fixed scale of prices which 
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. 
7. 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.
