Contributors can avoid delay in the publication of their work by conformingwith the following arrangements:The Journal of Experimental Biology will publish contributions in experimental biology and comparativephysiology, whether zoological or botanical. Every paper must contain a summary of the chief resultsof the enquiry. Authors are requested to present their work in as concise a form as possible. They willreceive 50 copies of their papers free; additional copies, not exceeding 100 (except in special cases), maybe purchased and should be ordered when the proofs are returned to the Editors.

All communications should be addressed to the Editors,

The Journal of Experimental Biology, Zoological Laboratory,Downing Street, Cambridge, England.

MANUSCRIPTS :

MSS. should be typewritten on one side only of the paper, and the pages should be numbered. Allparagraphs to be printed in small type should be indicated by adding a line at the side of the copy.Tables and Legends should be on separate sheets from the rest of the MS. and should be numbered.The place where they are to be inserted in the text should be indicated in the margin of the MS.Bibliography should be given under the heading of 'References' and in the following form: Surnameof authors (in alphabetical order), initials, date of publication, title of paper, title of journal (abbreviatedaccording to the WorldList of Scientific Periodicals), volume and page of reference. In the text a referenceshould be quoted by the author's name and date (in brackets), and not by the numerical order of thepaper in the list of references. All names of journals and books will be printed in italics.Bodies of numerical data, too extensive for complete publication, should be summarizedfor discussion, and the originals deposited in the Archives established for this purpose atthe British Museum (Natural History).

ILLUSTRATIONS :

(i) Line blocks should be used whenever possible. Illustrations should be pen drawings in Indian ink{jet black and water-proof) on smooth white Bristol board, the lettering being temporarily and lightly putin by the author with a soft pencil. It is best for the author to allow the skilled draughtsman or type-setter to deal with the final lettering. The size of the lettering inserted into the original drawing shouldbe graded according to the degree of reduction that is desired in the final reproduction. All brush tcork,tinting, or pencil shading is to be avoided. Where considerable reduction is required, it is essential thatthe drawing should be of such a character as to bear such reduction.(ii) Plates. Drawings should be executed on white drawing paper or card (yellowish backgrounds shouldbe avoided), and gummed on white card grouped and numbered in the order in which they are *oappear in the published plate. Exclusive of margin the plate-figures should not cover, when reduced,an area greater than 7} ins. in length x 5 ins. in width when ready for reproduction as a single plateor 7$ ins. x 1 ii ins. in the case of double plates. All lettering should be put in faintly with pencil. Forthe reproduction of photographs by the half-tone process a good glossy bromide print is required. Alllettering to appear on photographs should be shown in position on a covering sheet of transparentpaper. If a part only of the photograph is required it should be indicated in the same way.Charts and curves are frequently drawn to best advantage on graph paper ruled in pale blue since,whilst ensuring accuracy, the blue lines do not appear in the photograph, only the blackened lines thatare desired remaining.

PROOFSHEETS :

Authors will receive one set of slip proof for correction and return to the Editors. A page proof willalso be sent if the slip proof is marked by the author ' Revise'. An allowance of ten shillings per sheetof sixteen pages will be made for alterations apart from printer's errors. Authors may be charged forany excess over this average.

THE SOCIETY FOR EXPERIMENTAL BIOLOGY

The Society exists for the promotion of experimental biology. It holds Conferences, generallyfour times a year, at which the results of experimental investigations are presented anddiscussed. The Journal of Experimented Biology is the medium of publication of the Society.Enquiries about membership of the Society should be addressed to the Secretaries:

Prof. W. T . WILLIAMS, Department of Botany, University College, Southampton

Dr J. W. BEAMENT, Department of Zoology, Cambridge \
