Hydrogenation of Aromatic Compounds at Temperatures Close to their Decomposition in the Presence of Catalysts. By Vladimir Ipatieff. Page 3696. In text line 13 the temperature given is in centigrade degrees. Page 3697. The first naphthalene formula is incorrect in that it has two extra carbon atoms. Pages 3699 and 3700. The accompanying Table I1 should replace the Table I1 now on page 3699, and this table should be placed as Table I11 on page 3700 near the now incorrect reference to Table I1 in line 15.
