CORRECTIONS

In the article by N. A. Kiselev and L. L. Kiselev, “Electron Microscopy of Soluble Ribonucleic Acids,” published in DAN, vol. 141, no. 4, 1961, the following caption should appear for Fig. 1:

Fig. 1. A — S-RNA from wheat germs in acetate-ammonium buffer \((\mu = 0.16)\); \(130\,000\times\); ratio of object height to shadow \(1 : 7.5 \pm 1\). B — S-RNA from yeast \((\mu = 0.15)\); \(130\,000\times\); ratio of object height to shadow \(1 : 7.6 \pm 0.5\). C — S-RNA from yeast in water \((\mu = 1 \cdot 10^{-5})\); \(200\,000\times\); ratio of object height to shadow \(1 : 8.4 \pm 0.5\).

In the article by A. Sh. Faitelson, “The Riga Pre-Devonian Depression,” published in DAN, vol. 140, no. 1, 1961, the caption to Fig. 1 should read: Contour of the Riga Pre-Devonian depression.

In the article by V. V. Petrov, “On Integral Theorems for Large Deviations,” published in DAN, vol. 138, no. 4, 1961, the following corrections must be made:

On p. 779, line 7, \(X_1,\ X_2\) is printed; it should read: \(X_1,\ X_2,\ldots\)

On p. 779, line 13 from the bottom, it is printed

\[ \frac{s}{2(s+3)} < a, \]

it should read:

\[ \frac{s}{2(s+2)} < a. \]

In my article (L. G. Mikhailov, “On One Boundary Value Problem of Linear Conjugation”), published in DAN, vol. 139, no. 2, 1961, on p. 294 in Theorem 1 the condition \(|a(t)| > |b(t)|\) was omitted, and on p. 297, line 8, in the expression \(G(t)\), instead of \([b_1(t) - b_2(t)]\) it should be \([b_1(t) - a_2(t)]\).
