Inability to detect Chlamydomonas microtubule assembly in vitro: possible implications to the in vivo regulation of microtubule assembly INFORMATION FOR CONTRIBUTORS 1 Manuscripts should be sent to The Editors, Journal of Cell Science, Department of Zoology, Cambridge CB2 3EJ, England. 2 Manuscripts must be typewritten, in double spacing throughout (including tables, references and legends). Each table should be typed on a separate sheet. Legends to figures should be typed in a single series and placed at the end of the manuscript. Papers must be fully corrected by the author, and a charge will be made for excessive alteration in proof. 3 A short title of not more than 40 characters, for use as page headings, should be supplied if the full title is longer than this. 4 Manuscripts must contain a Summary of not more than 500 words, placed immediately after the title page. Contributors should also send two copies of an Abstract for distribution to abstracting journals. The abstract must not be more than 100 words long and should be headed by the author's name and address and the title of the paper. Both summary and abstract must be intelligible without reference to the main text. 5 The list of References must be given in alphabetical order of authors' names. The titles of journals should be abbreviated in accordance with the World List ofScientific Periodicals, 4th ed. (1963). The following style is used: GRAY, E. G. & WILLIS, R. A. (1968). Problems of electron stereoscopy of biological tissue. J. Cell Sci. 3, 309-326. MAZIA, D. (1961). Mitosis and the physiology of cell division. In The Cell, vol. 3 (ed. J. Brachet & A. E. Miraky), pp. 77-412. New York and London: 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 first citation should include all the names and subsequent citations should be in the form (Jones et al. i960). Where more than one paper by the same authors) have been published in the same year they are cited as Jones (1960a), Jones (19606) etc. 6 Footnotes should be avoided wherever possible. 7 SI units should be used throughout in the preparation of manuscripts. 8 Text figures should preferably be drawn about twice final size; very large drawings should be avoided. Photographic reproductions of drawings cannot always be satisfactorily reproduced. The maximum printed size of a drawing is 200 mm by 125 mm. Lettering will be inserted by the printers and should be indicated on drawings in faint blue pencil or on a tracing-paper overlay. It should be in lower case, and abbreviations should not be used if there is space for complete words. 9 Photographs should preferably be submitted the same size as they are to appear. The maximum area for a plate is 210 mm by 140 mm. Where several photographs make up a plate they should be accurately mounted on one sheet of cardboard. Irregularly shaped photographs or plates should be avoided wherever possible. Lettering on plates will be inserted by the printers and should be indicated either on a duplicate, marked set of prints or on a tracingpaper overlay bearing accurately marked outlines of the objects indicated. Authors may be asked to contribute to the cost of plates in excess of four. 10 Text figures and photographs should be numbered in a single series, all text figures preceding the photographs. Each individual drawing or photograph should be numbered separately (Fig. 1, Fig. 2 and so on). 11 Authors will receive 50 offprints free of charge and may order additional copies when proofs are returned.
