The annual index to products advertised in Science [134, 1253 (20 Oct. 1961)] contains an error in the listings for counters on page 1266. The counters now listed under "Counters, Whole Body," which were advertised at various times during 1961 by Packard Instrument Co., Inc., and Nuclear Chicago Corp., should, with one exception, have appeared under "Counters, Liquid Scintillation, Automatic." The exception is that the last entry for Packard Instrument Co. (15 Sept., 702) should remain under "Counters, Whole Body."
