INSTRUCTIONS TO AUTHORS. 



Owing to the cost of printing, the Publication Committee 

 beg to draw the attention of Authors submitting papers for 

 publication by the Society to the following Regulations. If the 

 conditions are not observed, papers may have to be returned : — • 



1. MSS. submitted for publication must be written in a clear 

 and legible handwriting, or, preferably, be type-written, and 

 must be in final form for printing. The MSS. should be written 

 on one side of each sheet only, and the pages clearly numbered. 

 All tables of contents, references to plates, or legends to 

 illustrations in the text, etc., must be in their proper places, 

 with page and plate numbers left blank ; and the position for 

 the text-figures must be indicated. References to literature must 

 be exact, with the page number as well as the volume number 

 and date. 



2. Proofs and their Correction. — Two copies of the slip 

 proof, and a page proof for final revision, will be sent to the 

 Author, but it is important that all serious corrections be 

 made on the slip proof. Expenses for proof corrections are very 

 heavy, but, if the MSS. comply with Regulation 1, should not 

 exceed 25 per cent, of the printers' charges. If the cost of 

 corrections exceeds 25 per cent., a proportion of the excess will 

 be charged to the Avithor. 



3. Revised proofs must, if possible, be returned within one 

 week from the date of their receipt by the Author. 



4. The Author receives 30 copies of reprints free, and, with 

 the sanction of the Publication Committee, may obtain leave to 

 buy extra copies, at the cost price charged by the printers and 

 engravers to the Society. The number of separate copies 

 required must be stated when returning the proof. 



5. Illustrations. — Drawings intended to be reproduced as 

 line-block text-figures should be drawn with a good black ink, 

 such as "Process Black" or the best "Indian ink" on white 

 " Bristol board." All lines and dots must be clear and sharp, 

 and no washes or colours used. Wash drawings are not suitable 

 for reproduction as text-figures. All necessary lettering must
