Query: Quenched results on $B$ Mesons with NRQCD   Preliminary results on spectrum and decay constant of $B$ mesons from a
quenched simulation at $\beta = 6.0$ on an $16^3\times48$ lattice are
discussed. The heavy quark has been implemented using both an NRQCD and the
static formulation, the light one with a clover improved Wilson formulation.
Both the NRQCD Hamiltonian and the heavy-light current consistently include
terms of $O(1/M_{Q})$, the inverse heavy quark mass.
