In the report "Reductive dechlorination of DDT to DDD by yeast," by B. J. Kallman and A. K. Andrews [Science 141, 1050 (13 Sept. 1963)] there are two errors in Fig. 1. Structure II requires a para chlorine on the second benzene ring, and in structure III the group bound to the carbon atom between the rings should have been Cl-C-H instead of Cl-C-Cl.
