  Standard Model fits are performed on the most recent leptonic and b quark Z
decay data from LEP and SLD, and FERMILAB data on top quark production, to
obtain $m_t$ and $m_H$. Poor fits are obtained, with confidence levels $\simeq$
2%. Removing the b quark data improves markedly the quality of the fits and
reduces the 95% CL upper limit on $m_H$ by $\simeq$ 50 GeV.
