In the report "Heart rate: changes during conditioned suppression in rats" by L. de Toledo and A. H. Black (3 June, p. 1404), a line of type was dropped. On page 1404, column 3, the third full paragraph should have begun "Heart rate was recorded from permanently implanted Grass disc electrodes (5)."
