Tables require a heading and figures a legend, also prepared on a separate sheet.
Due to technical reasons, figures with a screen background should not be submitted. On the back of each illustration, indicate its number, the author's name, and 'top' with a soft pencil. Color illustrations are reproduced at the author's expense. The list of references should include only those publications which are cited in the text. The surnames of the authors followed by initials should be given.
