  We report measurements of the pressure-dependent superconducting transition
temperature $T_c$ and electrical resistivity of the heavy-fermion compound
CeCoIn$_5$. Pressure moves CeCoIn$_5$ away from its proximity to a
quantum-critical point at atmospheric pressure. Experimental results are
qualitatively consistent with theoretical predictions for strong-coupled,
d-wave superconductivity in an anisotropic 3D superconductor.
