PROMPT PUBLICATION 



The Author can greatly assist the Publishers of this Journal 

 in attaining prompt publication of his paper by following these 

 four suggestions : 



1. Abstract. Send with the manuscript an Abstract containing 

 not more than 250 words, in the precise form of The Bibliographic 

 Service Card, so that the paper when accepted can be scheduled 

 for a definite issue as soon as received by the Publisher from the 

 Editor. 



2. Manuscript. Send the Manuscript to the Editor prepared 

 as described in the Notice to Contributors, to conform to the style 

 of the Journal (see third page of cover). 



3. Illustrations. Send the Illustrations in complete and fin- 

 ished form for engraving, drawings and photographs being pro- 

 tected from bending or breaking when shipped by mail or express. 



4. Proofs. Send the PubHsher early notice of any change in 

 your address, to obviate delay. Carefully correct and mail 

 proofs to the Editor as soon as possible after their arrival. 



By assuming and meeting these responsibihties, the author 

 avoids loss of time, correspondence that may be required to get 

 the Abstract, Manuscript and Illustrations in proper form, and 

 does all in his power to obtain prompt pubHcation.
