The mean life of mu /sup -/ mesons in Fe was measured using an improved cosmic-ray apparatus. A positive identification of the stopped muon was made using Cherenkov velocity selectors in the incident telescope. The 2.2 mu sec background from positive muons was reduced by a factor of 3 with a 3-layer sandwich of Fe and thin plastic scintillators, so arranged that electrons emitted in the target were mostly detected as such by the scintillators. The mean life is 196 the J-57 engin 8 m mu sec. By comparing this result with the electron- counting results of Lederman and Weinrich, the ratio of the decay rate of mu bound in Fe to the free mu /sup +/-decay rate is found to be 1.15 the J-57 engin 0.06.
