The authors report an improved measurement of the semileptonic branching fractions of B mesons. B mesons are produced in the reaction e{sup +}e{sup {minus}}{r_arrow}{Upsilon}(4S){r_arrow}B{bar B}, and have been analyzed with the CLEO II detector at the Cornell Electron Storage Ring (CESR). The data sample used for this analysis is substantially larger than has been used for any previous study. Semileptonic branching fractions have been extracted by fitting the inclusive electron and muon spectra to the refined free-quark model, and to the form-factor model. Consistency of the measured spectra with the theoretical models, including D, D*, D**(lv) production fractions, is assessed.
