The correct title of the paper by A. Sandow, S. R. Taylor, A. Isaacson, and J. J. Seguin [Science 143, 577 (7 Feb. 1964)] is "Electromechanical coupling in potentiation of muscular contraction." In the incorrect version, "Electrochemical" was substituted for "Electromechanical." In addition, the second sentence of the first paragraph on p. 578 should read "Calcium-EDTA and phosphate penetrate very slowly, if at all, into muscle fibers, and they form very tightly-binding complexes with Zn2+ and UO22+, respectively." In the original, calcium-EDTA and phosphate were transposed.
