  This is an addendum to the paper of the above title published in Physics
Letters B317, 159 (1993). In that paper, I found the lower bound to the Higgs
mass as a function of the top quark mass one obtains by requiring that the
standard model vacuum be stable. It included all higher order corrections to
two-loops, precise definitions of the Higgs and top masses, etc. Unfortunately,
the results were given for top quark masses between 120 and 160 GeV. In this
addendum, I give the results for masses between 160 and 190 GeV. The main
result, using a value of 0.117 for the strong coupling at the Z-mass, is
M_Higgs > 132 + 2.2 (M_top-170) in GeV units. This increases (decreases) by 4.5
GeV if the strong coupling decreases (increases) by 0.007, and is accurate to 1
GeV in the top mass. This will be submitted to Phys. Lett. as an addendum.
