Abstract Experiments on the preservation and soviing of
ailanthus seeds in Czechoslovakia indicated
the,; the highest germInation is attained at
the vernal scraing of stratified (84 days )
seeds. Tha preservatioi.-i (,f the seeds in xvin-
Uertime In small bags in a cool place produces
no -,x.)sIt~-.-7e results, Good results were obtai-
ned by the autumr-_'~]. so,viri.- of the seeds imme-

Abstract : The author derives the conditions (inequalities) governing the applica-
bility of approximations that were earlier employed by the author (ibid..,
27 (1954), 39-0 and 411), in which he considered the nucleon localized at
a discrete level in a self-consistent meson-field potential well and mov-
ing in a translatory and rotary manner with the well. He considers some
quantities which were not taken into account in the previous works men-
tioned as small perturbations.

Title : Calculation of polarons by direct variational methods

Abstract : The author checked the calculations of Lee, Low and Pines (Phys. Rev.,
90, 297, 1953) and persuaded himself that the number H-0.09 ev ob-
tained by them is in error; evidently they.had employed the author's
formula in his semiclassical theory of polarons (S. 1. Pekar, Zhur.
eksp. I teor. fiz., 16, 335, 341, 1946). The author shows the Inap-
plicability of the direct variational method, particularly the method
of Lee et alii, for calculating the effective mass of the polaron M;
e.g. they obtained M-1.9m In comparison with the author's and Landau's
M--150-400m etc. Ten references, 4 Western and 6 USSR (e.g. S. A. Tyab-
