BRITISH SOCIETY FOR CELL BIOLOGY

The British Society for Cell Biology was formed in April 1965 and its objects are' to promote the advance of research in relation to all branches of cell biology and toencourage the interchange of information'. The Society holds two meetings a year,consisting of a one-day symposium with invited speakers, followed by a general sessionfor proffered papers. Additional joint meetings with other societies, on special topics,are also held. It is hoped that the meetings of the Society will provide an opportunityfor those engaged in special fields in cell biology to present papers to a wider audience.

Members are entitled to receive the Journal of Cell Science at a reduced subscriptionrate (65*. per year).

Information about membership may be obtained from the Secretary/Treasurer:

Symposium on 'EXTRA-NUCLEAR DNA'

A symposium on this subject will form part of the next meeting of the Society atUniversity College, London, on 1 and 2 April 1966.

JOURNAL OF THE

MARINE BIOLOGICAL ASSOCIATIONOF THE UNITED KINGDOM

T H E ASSOCIATION was founded in 1884 to promote accurate researchesleading to the advancement of zoological and botanical science and to anincrease in our knowledge of the food, life, conditions, and habits of Britishfishes. The work of the Association is carried out at their laboratory at Plymouth,where a rich and varied fauna is to be found.

The journal contains records of the work done at the laboratory, togetherwith articles on original research in marine biology, physiology, and alliedsubjects from other research establishments in the British Isles and overseas.

The journal is issued three times a year, in February, June, and October.The subscription price is £11 per volume, post free; single parts 80^., pluspostage. Orders may be placed with your bookseller or sent direct to thepublishers:

Editors: B. C. J. G. K N I G H T AND A. F. B. S T A N D F A S T

The Journal of General Microbiology is conducted by the Society for GeneralMicrobiology, whose aim is to promote the advancement of microbiology byproviding a common meeting-ground for those working in all the various specializedfields, including, for example, medical, veterinary, agricultural and economicmicrobiology. The Society is concerned with the more fundamental aspects of thestudy of bacteria, viruses, micro-fungi, protozoa and microscopic algae in theirvarious biological activities, its members being united by the common aim ofdeveloping scientific knowledge concerning micro-organisms.

The subscription rate is £5 net per volume of 3 parts. Single parts 45s. each, pluspostage. Four volumes will be issued each year. Orders should be sent to

MICROSTRUCTUREOF CELLSAn Introduction for Sixth FormsSTEPHEN HURRY, MASt Paul's School

'This splendidly illustrated monograph is manifestly designed to provide the aspiring biologist withthe most up-to-date conception of the cell that it is possible for him to have.. .the author has clearlybeen at pains to get hold of the best prints available in every case and the publishers are to be con-gratulated on reproducing them large and bold enough for the student to suffer little confusion aboutjust what is being illustrated. There is no doubt that other books of this standard can do much togive scientific education the new look it so badly needs.' New Scientist

'Both the author and the publisher are to be complimented on the clarity of the photographs whichhave been carefully chosen to illustrate the features mentioned in the concise text.' Microscope

2 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.

Authors may, if they wish, omit titles of papers.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 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 (1960 a), Jones (19606) etc.

7 Text figures should preferably be drawn abouttwice final size; very large drawings should beavoided. Photographic reproductions of drawingscannot always be satisfactorily reproduced. Themaximum printed size of a drawing is 5 in. by8 in. Lettering will be inserted by the printers andshould be indicated on drawings in faint bluepencil or on a tracing-paper overlay. It should be inlower case, and abbreviations should not be used ifthere is space for complete words.

8 Photographs should preferably be submitted thesame size as they are to appear. The maximum areafor a plate is sJ in. by 8J in.

10 Where appropriate the magnifications ofillustrations should be indicated by scales drawn onthem. Magnifications may also be stated in thelegends.
