ACKNOWLEDGEIVIENTS Acknowledgements for permission to reproduce illustrations, photo- graphs, graphs, etc., should be listed at the end of the text. Acknowledge- ment to the author(s)' employers for permission to publish should not be made, because publication is deemed to indicate that such permission has been granted. II. PROOFS Page proofs will be sent to the first-named author for correction. In the interest of speedy publication galley proofs are no longer submitted to authors. The difficulty and expense involved in making corrections to page proofs makes it essential for authors to prepare their manuscripts carefully so that alteration is not required. 12. REPRINTS AND PREPRINTS The first-named author will automatically receive 25 reprints, or pre- prints where applicable, free of charge. Additional reprints must be ordered at the time the proofs are returned. June 1968
