The Third Wattis Symposium in Anthropology and this volume would not have been possible without the support of many devoted individuals. Mrs. Phyllis Wattis herself deserves greatest thanks for her continued generous financial support and her inspiring enthusiasm, which seems only to increase from one symposium to another. Within the California Academy of Sciences itself, Nancy Gee of the Department of Anthropology is thanked for the work she contributed toward the organization of the symposium, but most especially for her painstaking work in typesetting this volume.
