Both tables and figures must be referenced in the text. Illustrations that do not relate significantly to the text will be deleted. If saved as a separate image file, the author should indicate where the table or figure should be placed. Tables, table legends and figure legends should be double spaced. One copy of each illustration must accompany each copy of the manuscript.
Photocopies are satisfactory for the initial submission of the manuscript and review purposes.
Each figure should be identified on the back with number, author's name, and indication of the top of the figure. Lettering must be large enough for readability after the figure is reduced to fit the printed page. Scale should be indicated. No part of the figure should be typewritten. List all figure captions, double-spaced, on one separate page, not on the figures themselves.
