  We study $J/\psi$ suppression in Pb+Pb collisions at CERN-SPS energies in
hadronic matter with energy- and temperature-dependent charmonium dissociation
cross sections calculated in the quark-interchange model of Barnes and Swanson.
We find that the variation of J/$\psi$ survival probability from peripheral to
central collisions can be explained as induced by hadronic matter absorption in
central collisions.
