ERRATA Correlations between Chemical Structure and Normal B o i i Points of Halogenated Alkanes Cl'c4 [ J . Chem. Znj Comput. Sci. 32,233-237 (1992)l By Alexandru T. Balaban,' Nikhil Joshi, Lemont B. Kier,' and Lowell H. Hall. In Figure 6, captions for parts B and C should be interchanged, and B should be replaced by the accompanying figure, in which some lines have been omitted for clarity. The numbers of lines meeting at points labeled Xq,XSY,X2Y2, XzYZ,and XYZW should be 3,6,6,9, and 12, respectively.

Benzenoid Series Having a Constant Number of Isomers. 2. Topological Characteristics of Strictly Peri-Condensed Constant-Isomer Benzenoid Series [J. Chem. Znj Comput. Sci. 30, 251-256 (1990)l By Jerry Ray DiasDepartment of Chemistry, University of Missouri, Kansas City, Missouri 64 110-2499 Page 253. In the first column, line 8 should read: C70H20 is not found in Table PAH6 and, therefore, does not correspond to a benzenoid. In the second column, line 13 should read: Tables 1-11. Page 255. In Table IV the last section under even series should read: C42H18 C80H24 Cl30H30 C192H36 C266H42
