ERRATUM

In the article by V. D. Glezer, “Bulbous adaptation as a nervous process,” published in DAN, vol. 126, no. 5, 1959, in Fig. 2 on the abscissa axis, instead of 100 and 200 one should read \(10^0\) and \(20^0\); in Fig. 3 of the graphs, instead of 0.03; 0.05; 0.10; 0.25; 2.00 one should read \(0'03''\); \(0'05''\); \(0'10''\); \(0'25''\); \(2'00''\).

In the article by I. P. Alimarin and D. I. Kuznetsov, “o-Hydroxybenzenesulfinic acid—a new analytical reagent and structural analog of salicylic acid,” printed in DAN, vol. 131, no. 4, 1960, at the end of p. 822, formulas 1, 3, and 4 were included by mistake. There should be only the formula:

\[ \chemfig{*6(-=-(-[:60]O(-[:90]H)-[:0]Fe^{++})-(-[:300]S(=[:270]O)-)-=)} \]

In Fig. 3, on the abscissa axis, instead of the printed 12.0, it should be 10.0.
