  In this note it is shown that in his ``Comments'', Tsallis did not point out
any flaws in the main criticism of my paper, namely, that the nonextensive
q-entropy formalism fails to satisfy the zeroth law of thermodynamics. Details
are also given of a rigorous thermodynamic proof which demonstrates that,
contrary to Tsallis's assertion, the application of a nonextensive formalism to
black-body radiation does not lead to the well known $T^4$ Stefan-Boltzman law.
