Four copies should be provided in double-space typing on numbered pages of uniform size with a wide margin to the left. The name, complete postal address, telephone number, fax number and e-mail address of the corresponding author should be given on the first page of the manuscript. These should be indicated by numerals in square brackets, introduced consecutively in the text and must be listed at the end of the paper in numerical order. They should accompany the manuscript, but should not be included within the text. All illustrations should be clearly marked on the back with the figure number and the author's name.
All figures are to have a caption.
Captions should be supplied on a separate sheet. Good quality printouts on white paper produced in black ink are required. All lettering, graph lines and points on graphs should be sufficiently large and bold to permit reproduction when the diagram has been reduced to a size suitable for inclusion in the journal. Dye-line prints or photocopies are not suitable for reproduction. Do not use any type of shading on computer-generated illustrations.
