CORRECTIONS

In the article by I. V. Gostunskaya, V. A. Mironov, N. B. Dobroserdova, and B. A. Kazanskii, “On the chemical nonequivalence of active hydrogen sorbed by skeletal nickel catalyst,” published in Dokl. Akad. Nauk, vol. 153, No. 5, 1964, in Table 1, in the column “weight of hexane-1,” instead of the printed 0.33 g one should read: 3.3 g.

In our article (A. N. Nesmeyanov, N. S. Kochetkova, P. V. Petrovskii, E. I. Fedin, “On pentaethanodiferrocene”), published in Dokl. Akad. Nauk, vol. 152, No. 4, 1963, p. 876, line 18 from the top, instead of the printed cyclopentyldiferrocenylcarbinol, one should read: 1-ferrocenylcyclopentanol-1.
