NOTES FOR CONTRIBUTORS Available to Purchase

Articles should normally be around 5,000 words in length and will only be considered for publication if they have not previously been published. Two copies should be submitted, typed on one side of the paper, double spaced, and with broad margins. Authors using word processors should also observe these conventions. Diagrams should be drawn in black ink on separate sheets and should be of clarity and proportions suitable for photoreduction to page size. The name, designation, and full address of the author should be given, and an informative abstract of approximately 200 words, complete in itself, should be included.
