CORRECTION

In my article (D. N. Lenskii, “On an upper estimate of certain number-theoretic functions in fields of algebraic numbers”), published in Doklady, vol. 150, No. 2, 1963, the following corrections must be made:

P. 252, line 9: to the right-hand side of the inequality one should add the factor

\[ [\operatorname{Res}_{s=1}\zeta_K(s)]^{-w}. \]

P. 252, line 14: where “\(L\)-series” is printed, read “Dirichlet series.”

P. 252, line 1 from the bottom: on the right-hand side of the equality, the sign

\[ \sum_{i=1}^{m} \]

should be replaced by

\[ \prod_{i=1}^{m}. \]

P. 253, line 2: to the right-hand side of the inequality one should add the factor

\[ [\operatorname{Res}_{s=1}\zeta_K(s)]^{-m}. \]

In my article (V. F. Dërpgol’ts, “An attempt at a quantitative characterization of the Earth’s hydrosphere and chlorine”), printed in Doklady, vol. 150, No. 3, in Table 2, line 13 should read:

In the sedimentary rock mass    1,9   1,9—18

line 14 should read:

In crystalline rocks    8,6   8,8—82
