Acknowledgments, Revised Edition

My thanks are due the Mellon Foundation for the generous extension of administering my grant support for one more year, which has enabled me to finish this volume of revision. I express my gratitude as well to Dr. Yuan Zhou, Curator of our East Asian Library, and his able staff for continual assistance in research and acquisition of needed materials far and near, and to the Center for East Asian Studies, the University of Chicago, for its faithful support.
