ADDITIONS AND CORRECTIONS

Volume 34, Number 4 Changes in Peroxide Melt-Modified Poly(L-Lactide). Anders So¨derga˚rd,* Maria Niemi, Johan-Fredrik Selin, and Jan H. Na¨sman Page 1206. The bar to the right (no. 9) in Figure 2 is on the level 1.15. In accordance with Table 4 the correct height should be 1.81. IE9608216

Volume 34, Number 5 Kinetics of Thymol Hydrogenation over a Ni-Cr2O3 Catalyst. A. I. Allakhverdiev, N. V. Kul’kova, and D. Yu. Murzin* Page 1542. In Table 1 the following lines are now correct: 10. 13. 14. 20. 21.
