In the article " The hydrated electron" by E. J. Hart (2 Oct., p. 19), reaction 11 (column 1, page 20) was omitted. The ratio for the rates of reactions 9 and 10 was printed twice: correctly in place of reaction 11 and incorrectly in its proper place. The correct version follows:

The ratio for the rates of reactions 9 and 10, ke-aq+H2O2/KH+H2O2=500, attests to the high reactivity of e-aq compared to H atoms in this reaction.

Among other reactions showing this difference in reactivity is the effect of metal ions such as Fe3+ and Cu++ on the hydrogen yield in irradiated solutions of methanol (3). Hydrogen formed by reaction H+CH3OH→H2+CH2OH (11) is decreased by the addition of Fe3+ or Cu++ because the reaction e-aq+Fe3+→Fe++ (12) interferes with H-atom-producing reaction 4.
