Genetics and the Races of Man. An Introduction to Modern Physical Anthropology. William C. Boyd

theories propounded. The names of Wissler, Spier and Dixon are absent from the bibliography; Nordenskiold’s Comparative Ethnographical Studies are not discussed. Canals Frau’s thinking has been heavily influenced by the writings of his fellow countryman JosC Imbelloni, whose “culturology” has its roots in the work of Graebner and Schmidt. Imbelloni’s ascendency in academic anthropology in Argentina in recent years is very striking. It is curious and rather unfortunate that his theories have received so little critical attention in the United States. It would be a waste of space to call attention to the numerous factual errors, the misrepresentations resulting from the author’s process of selection, and the defective documentation, especially of the illustrations, that mar Canals Frau’s book. As I suggested above, the book is chiefly an exposition of the author’s theories and the amount of descriptive information given is very limited. While waiting for the ideal synthesis of American prehistory the reader will still do best to go to Martinez del Rio’s OrCgenes americanos (Mexico, 1943) rather than to Canals Frau’s new book.
