HEFFER & SONS LTD. 4 PETTY CURY CAMBRIDGE ENGLAND I94 ADVICE TO AUTHORS THE Council has approved the following notice by the Publication Committee which is here given in condensed form. The Society publishes papers concerned with all aspects of analytical chemistry, inorganic and organic as for example food and drugs analysis analysis of water (including its bacteriological examination) gas analysis metallurgical assays biological standardisation and micro-analysis.Papers on these and allied subjects may be submitted for presentation and publication; they may: (1) Record the results of original investigations into known methods or improvements therein ; (2) Record proposals for new iiiethods and the investigations on which the proposals are based; (3) Record analytical results obtained by known methods where these results by virtue of special circumstances such as their range or the novelty of the materials examined make a useful addition to analytical information ; (4) Record the application of new apparatus and new devices in analytical technique and the interpretation of results.Communications.-Papers (which should be sent to the Editor) will normally be sub-mitted to at least one referee on whose advice the Publication Committee will be guided as to the acceptance or rejection of any communication. Papers or Notes accepted by the Publication Committee may not be published elsewhere except by permission of the Commit tee. Abstracts.-The MS. should be accompanied by a brief abstract of about 100 to 150 words indicating the scope and results of the investigation. Manuscri+t.-Papers and Notes should preferably be typewritten. Notes on the writing of papers for THE ANALYST The title should be descriptive and should set out clearly the scope of the paper. Conciseness of expression should be aimed a t ; clarity is facilitated by the adoption of a logical order of presentation with the insertion of suitable paragraph or sectional headings.Generally the best order of presentation is as indicated below: (a) General including historical introduction. (b) Statement of object of investigation. (c) Description of methods used. Working details of methods are usually most concisely and clearly given in the imperative mood and should be given in this form a t least while economy of paper is pressing e g . “Dissolve 1 g in 10 ml of water and add . . .”. Well-known procedures must not be described in detail. ( d ) Presentation of results. (e) Discussion of results. (f) Conclusions. To be followed by a short summary (100 to 250 v\-ords) of the whole paper items (e) and ( f ) can often be combined.Illustrations diagrams etc.-The cost of setting up tabular matter is high and columns should therefore be as few as possible. Column headings should be brief or repiaced by a number or letter to be used in combination uith an explanatory footnote to the table. Sketches or diagrams should be on white Bristol board not larger than foolscap size, in Indian ink. Tables or graphs may be used but normally not both for the same set of results. Graphs should have the co-ordinate lines clearly drawn in ink. References.-References should be numbered serially in the test and collected in that order under “REFEREKCBS” a t the end of the paper. They should be given in the following form: Lettering should be in light pencil. 1. 2. I h n n J .T. and Noxam H. C. L. J . SOL Chem. Ind. 1933 52 1891’.
