If the author knows the HTTP address of a referenced article of the WWW, this information should be added at the end of the references. There should be minimal use of footnotes. Grant support of research should appear in a separate Acknowledgements section at the end of the paper, not in a footnote. Acknowledgements of the assistance of colleagues or similar note of appreciation also properly belong in an Acknowledgements section, not in footnotes. Footnotes within a table should be indicated by the same symbols listed above.
Type footnotes to a table directly beneath the table.
Keep figures separate from the text, but indicate an approximate position for each figure in the margin. The quality of line drawings and photographs must be of a high enough standard for direct reproduction. No additional artwork redrawing or typesetting will be done. Photographs intended for halftone reproductions must be glossy original prints of maximum contrast. All lettering must be clearly legible and be not less than 4 mm in height.
