ERRATUM

In the article by G. P. Kurbatkin, “Certain features of the behavior of ultralong waves in the atmosphere,” published in DAN, vol. 177, no. 4, 1967, on p. 824, line 4, instead of the printed \((^{1,2})\) one should read “(see reviews in \((^{1,2})\)).”

In the article by A. I. Belyaev and A. I. Yukovoi, “Influence of the third component on the behavior of impurities in zone melting of aluminum,” published in DAN, vol. 175, no. 6, 1967, the formula on p. 1259, line 22, should read \(\mathrm{Me}_1—\mathrm{Al} + \mathrm{Me}_2—\mathrm{Al}\).

In the article by E. I. Gladyshevskii, P. I. Kripyakevich, and R. V. Skolozdra, “The crystal structure of the compound \(\mathrm{Mo}_3\mathrm{CoSi}\),” published in DAN, vol. 175, no. 5, 1967, in Table 1, in the 2nd column, first line, instead of the printed Co one should read Mo.

On p. 1049, line 15 from the bottom, one should read: “we carried out by the method of two-dimensional Fourier series...”.
