Errata Second Law
Asymmetric Metal Compounds
The folloving changes should he made in "Our Freshmen Like the Second Law" by N. C. Craig 147,342 (1970)l.
An error appeam in the article "Resolution and Stereochemistry of Asymmetric Silicon, Germanium, Tin, and Lead Compounds" by Robert C. Bellali [46,640 (1969)l.
p. 342 Second line of eqn. (4): Si (cycle), not Sn (cycle). p. 344 Figure 4: Q' 1.35, not 1.35 Qf = 1.4, not 1.4 k In (Q'/Q'), not k In (Qfn') p. 345 Figure 5: The zero energy for B ( s ) (the bottom rung on the ladder) should be r, not 46.

Chemiluminescence The mechanism for the chemiluminescence of vioanthrone proposed in the note "A ChemiluminescenceReaction" by W. H. Slshaugh 147, 522 (1970)l has recently been updated. The mechanism is apparently a two-step excitation involving the lower triplet state of violanthrone and not the peroxide bridge intermediata. The interested reader is referred to the following
