INFORMATION FOR CONTRIBUTORS 



The length of contributions to GENETICS will not be arbitrarily limited, but artK.it. 

 less than fifty pages may be expected to appear more promptly than those of greater 

 gth. The limitation*, as to subject-matter will be construed broadly, so that any 

 per of sufficient importance, whether in the field of genetics proper, of cytology, 

 ibryology, physiology, biometry, or mathematics, if of such character as to be of 

 imary interest to the geneticist, will find here an appropriate place of publication. 

 Contributors are requested to observe the usual care in the preparation ef mam;- 

 ripts. All references to the literature should cite the name of the author, followed 



the year of publication, the papers so referred to being collected into a list of 

 Jterature cited&quot; at the end of the article. In this list great care should be taken bo 

 ve titles in full, and to indicate accurately in Arabic numerals, the volume number, 

 e first and last pages and the date of publication of each paper, if published ta a 

 riodical, and the number of pages, place and date of publication and name of 

 blishcr, of each independent publication. The arrangement of thi list should be 

 phabetical by authors, and chronological under each author. 

 Footnotes should be inserted immediately after the reference marks which refer to 

 em, and should be separated from the text by lines. All footnotes should be num 

 sred consecutively in a single series. 



No limitation will be placed on the kind of illustrations to be used, but as funds fot 

 lustration are still very limited, authors are requested to practice restraint, and to 

 mit themselves to such amount and grade of illustration as seem positively essential 



an adequate understanding of their work. The size of the type-forms of GENETICS 



4H X 7 1 /* inches and all illustrations intended for use as single plates should not 

 itceed 5 X 7f4 inches, or should allow of reduction to these dimensions. Double 

 ates may be i2j X ?H inches. Legends for all figures should be typewritten on a 

 eparate sheet.

 o extensive change may be made in page-proofs, which is not compensated for within 

 ic same paragraph, or in an adjacent paragraph on the same page. 



Contributors will receive 100 reprints of their papers, with covers, free of charge, 

 uid may secure additional copies at actual cost of manufacture, provided these are 

 &amp;gt;rdered when the corrected galley-proofs are returned.
