Correction.
A typographical error in Table 1 of my paper "The Validity of the Use of Tracers to Follow Chemical Reactions" (Science, 1949, 110, 14), under the entries for chlorine makes the estimated maximum ratios for the tracers Cl(36) and Cl(38) somewhat ambiguous. The stable isotopes should be written as Cl (natural abundance). The ratios were calculated for reactions with the tracers Cl(36) and Cl(38) in systems containing chlorine of natural isotopic abundance. Due attention has been given to the fact that the Cl(35) and Cl(37) will react at different rates.
