We calculate the fluctuation of a system's energy in Tsallis statistics
following the finite heat bath canonical ensemble approach. We obtain
this fluctuation as the second derivative of the logarithm of the
partition function plus an additional term. We also find an explicit
expression for the relative fluctuation as related to the number of
degrees of freedom of the bath and the composite system. (C) 2002
