Department of Physics & Astronomy, University of Tennessee, Knoxville, Tennessee 37916. Received 3 January 1975. Reinhard Beer's statement1 concerning new gases detect
ed in the atmosphere of Jupiter is not quite complete. In the spirit of the isotopic variants CH3D and HD, it should be mentioned that an identification of 13CH4 was also reported recently,2 and a Jovian 12C/13C ratio of 110 ± 35 was derived.
