Clearly contrasted prints are essential for adequate reproduction. Magnification is best indicated by a line representing a defined length, included with the photograph. Colour illustrations will be accepted when found necessary by the Editor, although the author will be expected to contribute to the cost. Diagrams should be on separate sheets. Lines should be of sufficient thickness to stand reduction.
Photocopies are unacceptable.
If submitting electronic images, all files must be supplied on a seperate disk and will be used where possible. TIFF images are preferred. Good quality hard copies of the figures must also be provided. Tables should be typewritten on separate sheets and given Roman numbers. References in the text should be made giving the author's surname with the year of publication in parentheses.
