The latest results of the lead-glass wall collaboration on anomalous electron production in electron--positron annihilations at center-of-mass energies from 3.77 to 7.4 GeV are given. Anomalous electron production was observed in two-prong events which is consistent with the heavy lepton hypothesis. The semileptonic branching ratio of the Dinto electrons is found. The branching ratios for heavy lepton decay were measured. Anomalous electron production was likewise observed in multiprong events. The semi-leptonic branching ratios for charmed particles into electrons was obtained under similar assumptions. Preliminary results are given. 40 references. (JFP)
