The charged-particle multiplicities of hadronic events deriving from produced bottom or charm quarks have been measured in the Mark II detector at PEP in e/sup +/e/sup -/ annihilation at 29 GeV. For events containing one semileptonic and one hadronic weak decay, we find multiplicities of 15.2 +- 0.5 +- 0.7 for bottom and 13.0 +- 0.5 +- 0.8 for charm. The corresponding multiplicities of charged particles accompanying the pair heavy hadrons are 5.2 +- 0.5 +- 0.9 for bottom, and 8.1 +- 0.5 +- 0.9 for charm.
