These should be placed at the end of the paper, numbered in Roman numerals and referred to in the text. If written by a person other than the author of the main text, the writer's name should be included below the title.

Tables should be self-contained and complement, but not duplicate, information contained in the text. Tables should be numbered consecutively in Arabic numerals. Each table should be presented with a comprehensive but concise legend. Tables should be double-spaced and vertical lines should not be used to separate columns. Column headings should be brief, with units of measurement in parentheses; all abbreviations should be defined in footnotes. Footnote symbols: †, ‡, §, ¶, should be used (in that order) and *, **, *** should be reserved for P-values. Statistical measures such as SD or SEM should be identified in the headings. The table and its legend/footnotes should be understandable without reference to the text.

All illustrations (line drawings and photographs) are classified as figures. Figures should be cited in consecutive order in the text. Line figures should be supplied as sharp, black and white graphs or diagrams, drawn professionally or with a computer graphics package; lettering should be included. Individual images forming a composite figure should be of equal contrast, to facilitate printing, and should be accurately squared. Images need to be cropped sufficiently to prevent the subject being recognized, or an eye bar used. Magnifications should be indicated using a scale bar on the illustration. Images should be supplied as high resolution (at least 300 d.p.i.) files, saved as .eps or .tif format. Digital images supplied only as low-resolution print-outs and/or files cannot be used.
