   <hidden TTP07-16  Determination of the strong coupling constant from the CLEO measurement of the total hadronic cross section in $e^+e^-$ annihilation below 10.56 GeV > Using recent CLEO III results for the cross section for $e^+e^- \to
 {\rm
 hadrons}$ at seven center-of-mass energies between 6.964 and
 10.538~GeV, we
 derive a value for the 
 strong coupling constant
 $\alpha_s(M_Z^2)=0.110_{-0.012}^{-0.010}{}_{-0.011}^{+0.010}$ 
 where the uncertainties are uncorrelated and correlated, 
 respectively. Our result differs by more than one standard
 deviation from the one derived by CLEO III, as a consequence of
 inclusion of
 quark mass effects and the proper matching between the effective
 theories with
 four and five flavours, respectively.
