Volume 26 August 1977

Journal of CELLSCIENCE

CAMBRIDGE UNIVERSITY PRESSFor the Company of Biologists Ltd

Journal of Cell Science is devoted to the study of cell organization. Papers will be publisheddealing with the structure and function of plant and animal cells and their extracellular products,and with such topics as cell growth and division, cell movements and interactions, and cellgenetics. Accounts of advances in the relevant techniques will also be published. Contributionsconcerned with morphogenesis at the cellular and sub-cellular levels will be acceptable, as willstudies of micro-organisms and viruses, in so far as they are relevant to an understanding of cellorganization. Theoretical articles and occasional review articles will be published.

Subscriptions. The Journal of Cell Science is published six times a year, in February, April, June,August, October and December. Each issue is a complete volume.

INFORMATION FOR CONTRIBUTORS

i Manuscripts should be sent to The Editors,Journal of Cell' Science, Department of Zoology,Cambridge CB2 3EJ, England.

a Manuscripts must be typewritten, in doublespacing throughout (including tables, references andlegends). Each table should be typed on a separatesheet. Legends to figures should be typed in asingle series and placed at the end of the manuscript.Papers must be fully corrected by the author, and acharge will be made for excessive alteration in proof.

3 A short title of not more than 40 characters, foruse as page headings, should be supplied if the fulltitle is longer than this.

4 Manuscripts must contain a Summary of notmore than 500 words, placed immediately after thetitle page. Contributors should also send two copiesof an Abstract for distribution to abstrating journals.The abstract must not be more than 100 words longand should be headed by the author's name andaddress and the title of the paper. Both summaryand abstract must be intelligible without referenceto the main text.

5 The list of References must be given inalphabetical order of authors' names. The titles ofjournals should be abbreviated in accordance withthe World List of Scientific Periodicals, 4th ed. (1963).The following style is used:

GRAY, E. G. & WILLIS, R. A. (1968). Problems ofelectron stereoscopy of biological tissue. J. CellSci. 3, 309-326.

MAZIA, D. (1961). Mitosis and physiology ofcell division. In The Cell, vol. 3 (ed. J. Brachet& A. E. Mirsky), pp. 77-412. New York andLondon: Academic Press.

Citations in the text are given in the following form:Jones & Smith (i960) or (Jones & Smith, i960).Where there are more than two authors the firstcitation should include all the names and subsequentcitations should be in the form (Jones et al. i960).Where more than one paper by the same author(s)

have been published in the same year they are citedas Jones (1960a), Jones (19606) etc.

6 Footnotes should be avoided wherever possible.

7 SI units should be used throughout in thepreparation of manuscripts.

8 Text figures and photographs should benumbered in a single series, in the order in whichthey are referred to in the text. Each individualdrawing or photograph should be numberedseparately (Fig. 1, Fig. 2 and so on).

9 Text figures should preferably be drawn abouttwice final size; very large drawings should beavoided. Original drawings are needed for reproduc-tion as photographic copies cannot always be used.The maximum printed size of a drawing is 200 mmby 125 mm. Lettering will be inserted by the printersand should be indicated on a tracing-paper overlayor a duplicate copy.

10 Photographs should preferably be submittedthe same size as they are to appear. The maximumfor a plate is 200 mm by 140 mm. Where severalphotographs make up a plate they should beaccurately mounted on one sheet of cardboard andirregular shapes avoided wherever possible. Letteringon plates will be inserted by the printers and shouldbe indicated either on a duplicate, marked set ofprints or on a tracing-paper overlay bearing accu-rately marked outlines of the objects indicated.Authors may be asked to contribute the cost of platesin excess of four.

n Authors will receive 50 offprints free of chargeand may order additional copies when proofs arereturned.

12 In order to give the Company of Biologistsauthority to deal with matters of copyright, authorswill be required to assign to them the copyright ofany article published in the journal. Authors willnot, however, need to ask permission to re-use theirown material in other publications appearing undertheir own name.
