The Journal encourages the use of figures that help communicate the message of the text. Letters, numbers, and symbols must be clear throughout and large enough to remain legible when reduced for publication. Figures should be labeled on the back, indicating the figure number, author, and top of figure. Do not write directly on the back of the photographs. Use labels instead.
Protective packaging is recommended for mailing figures.
Legends should enable the figures to be understood without reference to the text. Previously published figures must include the appropriate credit line. Decisions of the Editor in Chief are final. All material submitted is subject to editing and copyediting. Authors will receive page proofs before publication.
