All the illustrations should contain the figure number and author's name in pencil on the reverse. The most important point with figures is clearness. Photographs and half-tone illustrations should be sharp and well contrasted. Only original papers will be published and a copy of the Publishing Agreement will be sent to the authors of papers accepted for publication. Manuscripts will be processed only after receiving the signed copy of the agreement.
Information is sent to the first author if no other wish is expressed.
