  The measurements performed at LEP and SLC have substantially improved the
precision of the test of the Minimal Standard Model. The precision is such that
there is sensitivity to pure weak radiative corrections. This allows to
indirectly determine the top mass (\mt=161$\pm$8 GeV), the W-boson mass
(\MW=80.37$\pm$0.03 GeV), and to set an upper limit on the the Higgs boson mass
of 262 GeV at 95% confidence level.
