The principle of the sodium sulfate cryoscopy and a set-up for the use of this method to determine the molecular or inoic weight of the foreign matter in solution are described. Among the precautions that should be taken in order to obtain reliable results, the way of taking the transition temperature is of special importance.

The principle of the sodium sulfate cryoscopy and a set-up for the use of this method to determine the molecular or inoic weight of the foreign matter in solution are described. Among the precautions that should be taken in order to obtain reliable results, the way of taking the transition temperature is of special importance. The transition temperature is neither that taken at a definite time, say 15 minutes, after the introduction of seeding crystal nor the maximum of the rising temperature, but should be obtained by extrapolation of the regularly descending portion of the time-temperature curve to the initial time.

In this paper the formation of eccentric circumpolar vortex in the troposphere and the stratophere is studied by integrating the simple non-linear dynamic equations in a 3-layer model.It is shown that the quasi-permarence of large-scale asymmetric circulations is produced by the orographic and thermal influences. The position and the in-tensisty of the tropospheric circumpolar vortex on the 5th day from the initial time is similar to the synoptic empirical results.The dynamical properties of the circumplar vortex are also discussed from the influence coefficents of the equations (11)-(14).
