The lettering must be clear and open and must be large enough to be reproduced in the same proportion as the figure itself. If this is not possible, the lettering may be provided on a tissue overlay. Please do not make any marks or identification on the figures themselves. A label must be attached to the back of all photographs and drawings indicating the author, the figure number, and the top of the photograph or drawing. Original drawings may be identified in the margin or on a tissue overlay.
Figures are to be numbered consecutively throughout the paper in Arabic numerals.
A complete list of all figure legends must be submitted as the last element of the typescript on a separate sheet or sheets. The first citation of a figure in text is to be noted in the margin for placement of the figure after typesetting. Tables Tables must be typed in double spacing on a separate sheet for each table and with a title for each table. Please number all the tables consecutively and give each column a short or abbreviated heading. Place explanatory matter in footnotes, not in the headings.
