It is the author's responsibility to obtain permission to reproduce illustrations, tables, etc. from other publications. A short title for use as running head and a translation of the full title into English as well as the full address of the author to whom correspondence should be sent are also required. Please also supply phone and fax numbers, as well as your e-mail address. Papers in French or German must also have a summary in that language of not more than 10 lines. When essential, they are numbered consecutively and typed at the foot of the appropriate page.
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. Year of publication in brackets.
