In the report "Visual evoked potentials as a function of flash luminance and duration" by Wicke, Donchin, and Lindsley (2 Oct., p. 83), the last sentence of the first paragraph of column 3 on p. 84 should have read: "These data indicate that the waveform and amplitude of the average evoked potentials depend on the total luminous energy of the flash and further suggest a relationship to apparent brightness, in accordance with Bloch's law."
