Information concerning grant support of research should appear in a separate Acknowledgments section at the end of the manuscript, not in a footnote. Acknowledgments of the assistance of colleagues or similar notes of appreciation also properly belong in an Acknowledgments section, not in footnotes. Type each footnote at the bottom of the typescript page on which its text call-out appears. Footnotes within a table should be indicated by the same symbols listed above. Reinitialize symbol sequence within tables.
Type footnotes to a table directly beneath the table.
Avoid use of vertical rules in tables. All figures should be numbered with consecutive Arabic numerals, have descriptive legends, and be mentioned in the text. Keep figures separate from the text but indicate an approximate position for each in the text. Figures accompanying the second and third copies of the manuscript may be photocopies. Original line drawings should be prepared in black ink on white art paper, with all lettering and symbols included.
