Abstract Using data samples taken at the {Upsilon}(4{ital S}) resonance and nearby continuum {ital e}{sup +}{ital e}{sup {minus}} annihilation with the CLEO-II detector at CESR, we have measured the inclusive branching fraction B({ital B}{r_arrow}{eta}{ital X})=(17.6{plus_minus}1.1{plus_minus}1.2){percent}, and the momentum distribution of the {eta} mesons from {ital B} meson decay. The {eta} yield cannot be explained as arising solely from the decay of intermediate charmed mesons. {copyright} {ital 1996 The American Physical Society.}
