Footnotes to a table should be indicated by lower-case letters in parentheses and typed directly under the table. Every figure must be referred to in the text. Figures will be printed in black and white. Figures must be submitted in sizes that do not exceed the size of the manuscript paper. If they are smaller than the manuscript paper, they should be pasted onto separate sheets.
All figures are to be numbered with Arabic numerals in the sequence in which they are cited.
Every figure must be accompanied by a legend. Legends are not to be typed under the figures, but should be collected on separate pages. The quality of the figures should be such that they can be reproduced directly after reduction to 85 mm width. Numbers, letters and symbols inscribed must be large enough to be still 1.5 mm high after the figure has been reducted to the printing format. Photographs or photocopies of drawings are not suitable for reproduction.
