E D I T O R I A L N O T I C E S

Papers submit ted for publication should be sent to the H o n . S e c r e t a r i e s , M a a s o n H o u s e , 26 P o r t l a n d P l a c e , L o n d o n , W.I . , and will be understood to be offered to this Journal alone. Those already issued even in mimeographed form will not be accepted for publication. T h e copyright of papers which are accepted becomes the proper ty of the Society ; but they may be republished by permission, provided that due acknowledgemcnt is made that they have appeared in the TRANSACTIONS.

Papers should be typewri t ten on one side of the paper only, in double spacing, with adequate margins. T h e y should be c o n c i s e l y wri t ten (many of those sent in are extravagantly long, with much needless repetition). T h e subject mat ter should be logically arranged and sub-divided ; with references and abbreviations in the form described below. Often a long review of the li terature of a subject is given and is no more than a copy of what has appeared many times before ; in such cases, a single reference to an earl ier compilat ion would cover much of the ground.

Authors are expected to revise their typescripts thoroughly before submit t ing them, and so galley proofs are sent for checking and not for rewording, unless some error or misstatement has become a p p a r e n t - - " It should be a point of honour not to inflict upon printers and publishers the burden of irritating afterthoughts and infirm vacillations."

Tables are costly to print and shouhl be as few as possible (the data in many of those submit ted could be adequately given in a few lines of text) ; they should be typed on separate sheets, numbered and referred to in the text by roman numerals. Each table should have its own explanatory heading.

G r a p h s and l ine d r a w i n g s should be in Indian ink on plain white paper, Bristol board or faintly blue-l lned paper. Letters, numbers , etc., should be clearly writ ten or stencilled in Indian ink. All graphs and line drawings should be larger than the probable size of the finished block, and care should be taken to allow for reduction in size of lettering. Legends and captions should be typed on a separate sheet and numbered to Correspond. Figures should be comprehensible without reference to the text,

I l l u s t r a t l o n s . - - I f the number sent in is considered excessive the author may be informed and given the opportuni ty of contr ibut ing to the cost of reproduction ; otherwise the number of illustrations may be reduced at the Edi tor ' s discretion.

C o l o u r e d p l a t e s are made only at the author 's expense. REFERENCES

All references should be given in the text, thus : " . . . it has been shown (MANSON, 1879) . . . " " I t has been shown by MANSON (1879) that . . . "

T h e final list of references should be arranged in alphabetical order according to the name of the first author cited, and should include (1) author 's name, (2) initial, (3) date of publication, (4) name of journal, (5) volume, (6) page number . (The titles of papers are not necessarily printed, but if given are helpful in checking references).

References to books should include (1), (2), (3) as above ; title of book, edition and/or volume if more than one, page number , town of publication and publisher 's name.

References to Annual Reports : SWAZILAND (1937). Annual Medical and Sanitary Report, 1936, p. 16. Note. - -The year of publication is not usually the year covered by the Report .

Abbreviations. Where possible, titles of journals should be shown as abbreviated in the W o r l d L is t o f S c i e n t i f i c P e r i o d i c a l s - in general, nouns have capital, adjectives small, initial letters ; articles, conjunctions and prepositions are omit ted ; the place of impr in t is added only when un- certainty might arise ; thus Trans. R. Soc. trop. Med. Hyg., Indian ff. reed. Res., Nature, Lond., ff . Amer. reed. Ass.
