INFORMATION FOR CONTRIBUTORS 



The length of contributions to GENETICS will not be arbitrarily limited, 

 but articles of less than fifty pages may be expected to appear more promptly 

 than those of greater length. The limitations as to subject-matter will be 

 construed broadly, so that any paper of sufficient importance, whether in the 

 field of genetics proper, of cytology, embryology, physiology, biometry, or 

 mathematics, if of such character as to be of primary interest to the geneticist, 

 will find here an appropriate place of publication. 



Contributors are requested to observe the usual care in the preparation of 

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

 followed by the year of publication, the papers so referred to being collected 

 into a list of "Literature cited" at the end of the article. In this list great 

 care should be taken to give titles in jull, and to indicate accurately in Arabic 

 numerals, the volume number, and first and last pages and the date of publi- 

 cation of each paper, if published in a periodical, and the number of pages, 

 place and date of publication and name of publisher, of each independent 

 publication. The arrangement of this list should be alphabetical by authors, 

 and chronological under each author. 



Footnotes, legends for figures, tabular matter, and quotations involving 

 more than one sentence should be typewritten on separate sheets. All foot- 

 notes should be numbered consecutively in a single series and designated by 

 Arabic superscript numerals. 



No limitation will be placed on the kind of illustration to be used, but as 

 funds for illustration are still very limited, authors are requested to practice 

 restraint, and to limit themselves to such amount and grade of illustration as 

 seem positively essential to an adequate understanding of their work. The 

 size of the type-forms of GENETICS, exclusive of the heading, is 4f X7 inches 

 and all illustrations intended for use as single plates should not exceed these 

 dimensions or should allow of reduction to them. Double plates may be 

 12JX7 inches. 



Authors will receive galley-proofs, and, if specially requested, page-proofs 

 will be sent also, it being understood that the latter must be returned very 

 promptly, and that no extensive change may be made in the page-proofs, 

 which is not compensated for within the same paragraph, or in an adjacent 

 paragraph on the same page. Changes from copy will be charged against the 

 author. 



Contributors will receive 50 reprints of their papers, with covers, free of 

 charge provided not fewer than 100 are ordered. If a less number is desired 

 one-half the total cost of their manufacture will be charged to the author. 

 Additional copies may be secured at actual cost of manufacture, provided 

 these are ordered when the corrected galley-proofs are returned. 



Manuscripts and all editorial correspondence should be addressed to the 

 Managing Editor, DR. GEORGE H. SHULL, 60 Jefferson Road, Princeton, 

 New Jersey, U.S.A.
