CORRECTION.
THE 1942 U.S.D.A. Yearbook, "Keeping Livestock Healthy," page 1096, fails to give proper credit to the research workers responsible for the experimental production of goiter in poultry. This was first accomplished in 1938 by A. R. Patton, H. S. Wilgus, Jr., and G. S. Harshfield (SCIENCE, 89: 162, 1939).
