Notes to ContributorsAuthors of papers for Zambezia are requested to studythe following instructions carefully in order that paperssubmitted for publication conform to the style andlayout in this journal.Articles which have been, or are to be, publishedelsewhere cannot be accepted.1. LengthWhile articles do not normally exceed 6,000 words,long articles of exceptional interest will be considered.Short research reports and book reviews of 500 to 1,000words are welcomed.2. General FormSo variable is the scope of articles submitted toZembezia that it is difficult to lay down any invariableform which these should follow. Whenever possible,however, and certainly in the case of articles reportingexperimental or technical results, the following sequenceshould be adhered to:ŠIntroduction, stating object and scope of the study,with a brief history of the subject. The word "Intro-duction" should not appear as a heading.Methods or techniques, with description of subjects,materials and apparatus.Results, with illustrations, tables, graphs and dia-grams, where necessary. The presentation of informa-tion both in tabular and illustrative form, and similarrepetitions, should be avoided.Discussion, giving concise interpretation of resultsand their significance.Summary, to be brief and containing only the salientpoints of the article, preferably enumerated. Itshould be suitable as an abstract and should thereforenot be combined with "Conclusions."Acknowledgments, where necessary.References.3. Manuscript3.1 Articles should be typed in double spacing, theoriginal and first carbon copy to be submitted, onfoolscap or A.4 size paper, using one side only.A margin of 1-1-$ inches (2J-4 cm.) should beleft on both sides and at the head of each sheet;the sheets should be serially numbered and securelyclipped (not stapled) together.3.2 UnderliningAccording to international printing convention, anywords underlined are printed in italics. Thereforeunderline only those words which must appear initalics. For instance, underline those parts ofreferences which have to appear in italics, viz. titlesof books and names of periodicals (see below, 5.6).All other underlining, e.g., to indicate bold typeprinting, should be left to the editors. Authorsmay indicate their special requirements in a separatenote, or in brief marginal notes in pencil.4. Title, headings, sub-headings, etc.4.1 Title and authorIn the typed manuscript the TITLE of the articleshould appear two inches (5 cm.) from the topof the page in CAPITALS, centred on the page,without any underlining and without a full stop.The next line should contain the author's name(authors' names) in upper and lower case, centred,without underlining, without the word "by" andwithout a full stop.Below the author's name (authors' names) his/her(their) working place (university, institute, etc.)should be given.

The sub-headings used for this pur-pose must be underlined, and centred if furthersub-headings are to be used (see below).4.4 Further sub-headingsAs far as possible inferior headings of this kindshould be avoided. If further sub-headings areessential they should be typed as shown in thefollowing example:ŠMaterialsGroup Tests (italics in separate line, notcentred)The youngest age at which . . . tested ifnecessary.Individual TestsPicture Arrangement Tests: Tests in thiscategory . . . without exception (sub-head-ings in italics, with text in same line).Sentence Completion: Unlike the . . .research setting.4.5 ACKNOWLEDGMENTSThis heading to be typed in capitals, not centred,but separate line, not underlined. Acknowledg-ments should be made only to persons who madeessential contributions to the work reported.4.6 REFERENCESThis heading to be typed in capitals, centred, notunderlined.5. References5.1 Citation should follow one of the following sys-tems:81EITHERa References should be indicated in the text bydate of publication following the author's name,e.g., Brown (1952), or Brown (1952, p. 160); ifthe author has two or more publications in thesame year, the form should be Brown (1952a).Where the author's name has not been includedwithin the text, it should appear with the date ofpublication, e.g, (Brown, 1952).The list of references at the end of the articleshould be in alphabetical order of authors' names,and also in order of date when several works bythe same author are cited.ORb A number should be inserted in the text andthis will refer to notes which contain the fullreference and /or any other material in the formof expansion or qualification; e.g., ... as Brownhas pointed out.(i) These enumerated referenceswill be printed individually at the foot of the re-levant page or together at the end of the article,at the Editor's discretion, e.g., 1. BROWN, B. R.1962 History of Rhodesia. London, Macmillan,p. 62.5.2 In the list of references, only published or suchunpublished material as theses, internal reports,etc., should be included which is available in docu-mentary form at a recognised library or institution.Personal communications and material which isonly intended for publication are not acceptablein a reference list and should be related in foot-notes. Manuscripts in press may be included in thereference list if they have been accepted for pub-lication by recognised journals or publishers. Inthis case the name and volume number and/oryear in which they are to appear or the publisher'sname must be given, followed by the words "inpress."5.3 If quotations have to be made on the basis ofsecondary sources, this should be indicated, e.g.,quoted after Black (1965), or Black.(i)5.4 Abbreviation! should be according to the list ofabbreviations as given in Vol. Q-Z of World Listof Scientific Periodicals, 4th edn. 1963-1965.5.5 The style of references(i) Books:ŠBROWN, B. R. and SMITH, H. 1963 Witch-craft in Northern Dayna. Cambridge, Mass., Mac-millan, p. 69.FISHER, H. G. et al. 1961 Aggression. London,Cassell.WALTON, G. F. 1962 Elements of Economics,3rd edn, Baltimore, Houghton, Mifflin.(ii) Journals:ŠBEDFORD, D. 1938a The Education of Ex-ceptional Children. J. exp. Psychol., 3, 172-186.(iii) References to chapters or contributions inbooks:ŠSTENDLER, C. B. 1958 Values and Class, In:MELTZER, B. N., ed., Education in Society.Readings. New York, Crowell.(iv) Official Publications, Reports, etc.:ŠNORTHERN RHODESIA. 1964 The BritishSouth Africa Company's Claims to MineralRoyalties. . . . Lusaka, Government Printer, p. 2.(v) Documents:ŠCHIEF NATIVE COMMISSIONER. In Letters,Gwelo [hereafter cited as N 1/1/12], Jones toTaylor, 3. viii. 1897.(vi) Repeated reference in footnotes to a sourcealready cited should be by a consistent form:e.g., BROWN, p. 8 or BROWN, History ofRhodesia, p. 8.6. Tables and figures are costly to print and should beused only when they save space and/or are essentialfor effective presentation. The same material shouldnot be presented in a table and a graph. Each tableor figure should be numbered (N.B.: tables inRomans, figures in Arabic), on a separate sheet, andits approximate position indicated in the typescript.Drawings should be in Indian ink on heavy, unruledpaper, the lettering on graphs being in pencil. Linesin tables should be ruled in pencil. Each table orgraph should have a short title, sufficient for under-standing without searching in the text. (Note: Zam-bezia is printed in double column.)7. Corrections. The Editorial Board cannot considerfor publication articles which are seriously deficientin presentation. The typescript submitted (after pre-liminary consultation, if desired) should represent thefinal form in which the author wishes the paper toappear. Since changes in proof are costly, out of al!proportion to the original setting, authors may becharged for any changes, insertions or deletions otherthan printer's errors.8. Reprints. Authors receive 10 copies of their papersfree. Extra copies, in multiples of 10, may be had atcost price if the order is given when the proof isreturned.82LOOAL_SBffiCB?
