Because of an editorial error, Fig. 1, of the report on Autoradiographic Distribution of Radioactive Sodium in Rat Kidney [Science 143, 695 (14 Feb.)] was incorrectly described as a reverse autoradiograph. Because these are normal autoradiographs, the dark, not the light, areas denote deposition of the radioisotope. In the legend of the cover photograph (p. 631), which is associated with this report, the word "Reverse" should be deleted and in the third line the word "dark" should replace "light." The first six lines of the legend of Fig. 1 (p. 696) should read: "Autoradiographs of cross sections, parallel to the long axis of the kidney, from rats injected with Cl36 (A); and with inulin-C14OOH (B). In each section, dark areas denote deposition of the radioisotope . . ."
