The continuum limit in the quenched approximation

Previous work at $6\mathrm{/}{g}^2=5.7$ with quenched staggered quarks is extended with new calculations at 5.85 and 6.15 on lattices up to ${32}^3\times 64$. These calculations allow a more detailed study of extrapolation in quark mass, finite volume and lattice spacing than has heretofore been possible. We discuss how closely the quenched spectrum approaches that of the real world.
