The Physical Anthropology of the American Indian. William S. Laughlin, Editor. New York, The Viking Fund, Inc., 1951. vii + 202 pp., numerous illustrations. The six papers by as many authors contained in this volume, although significant contributions, hardly fulfill the ambitious covering title. Actually, on the inside cover the title is properly qualified by the words "Papers on…" Selected from a larger number of invited papers delivered at the Fourth Viking Fund Summer Seminar in Physical Anthropology held in September, 1949, these papers mostly unite in stressing the genetic approach to the study of man. The broad significance of each is all that will be pointed out here.
