CORRECTION

In the article by L. A. Dikarev, “On the characteristic temperature of suspensions,” published in DAN, vol. 163, No. 6, 1965, the following correction must be made: on p. 1356, line 11, printed

\[ \xi = (\rho_1/\rho_2)(\nu_1 - z_2^2)^2 - 1, \]

should be

\[ \xi = (\rho_1/\rho_2)(\nu_1/\nu_2^2) - 1. \]
