In my article (D. N. Andreevskii, “Equilibrium of the Isomerization of Bromopropanes”), published in DAN, vol. 135, no. 2, 1960, on p. 315, lines 4 and 5 should read:

From the calibration curve of standard mixtures, the content in the liquid phase of 1-bromopropane is estimated at \(1.30 \pm 0.05\%\) (for a temperature of 60°).
