We report the observations of the decays B+ψ(2S)K+ and B0ψ(2S)K*(892)0 in pp̅ collisions at a center-of-mass energy of 1.8 TeV using a 110pb-1 data sample recorded by the Collider Detector at Fermilab. We also reconstruct the decays B+J/ψK+ and B0J/ψK*(892)0 and measure the six ratios of branching fractions of these four decays. The relative branching-fraction results are shown to be consistent with phenomenological factorization calculations of hadronic B-meson decays. We use the world-average branching fraction B(B+J/ψK+) to derive B(B+ψ(2S)K+)=(0.56±0.08±0.10)×10-3, B(B0ψ(2S)K*(892)0)=(0.92±0.20±0.16)×10-3, and B(B0J/ψK*(892)0)=(1.78±0.14±0.29)×10-3, where the first and second uncertainties are statistical and systematic, respectively.
