Recently a method has been developed for relating four dimensional Schwarzs
child black holes in M theory to near-extremal black holes in string theory
with four charges, using suitably defined "boosts" and T dualities. We sho
w that this method can be extended to obtain thr emission rate of low energ
y massless scalers for the four dimensional Schwarzschild hole from the mic
roscopic picture of radiation from the near extremal hole. [S0556-2821(99)0
