Type each table double-spaced on a separate page. Extensive tables will be reproduced photographically and so should be typed carefully and in the exact format desired. Authors will be charged for any new photoreproductions necessitated by changes in proof. All illustrations are to be considered as figures. Figures should be numbered consecutively with Arabic numerals.
Type legends double-spaced consecutively on a separate sheet.
Figures must be submitted in a form suitable for reproduction. Standard mechanical lettering sets or their equivalent should be used. Characters should be approximately 10 to 12 points high. In addition, symbols used to identify points within a graph should be large enough that they will be easily distinguishable after reduction . Graphs should be plotted on blue coordinate or white paper no larger than 8.5 x 11 in.
