A phrase was omitted from A. D. Kelmers' and M. P. Stulberg's letter "Purified Transfer RNA's" on page 238 of the 16 January issue. The sentence should have read: "The following transfer RNA's from E. coli K-12 MO7, fMet (97 percent), Arg (70 percent), Phe 2 (78 percent), and Glu (∼95 percent), and from E. coli K-12 MO, fMet (∼95 percent), Arg (100 percent), and Glu (∼85 percent) are ready for distribution."
