  We comment on the preprint cond-mat/9805103 by D. Braak and N. Andrei
\cite{BrAn98}. We point out that the ``new'' Bethe Ansatz equations presented
in \cite{BrAn98} are identical to the Bethe equations for strings introduced by
M. Takahashi for the description of thermodynamics in 1972 \cite{Takahashi72}.
Some physics suggested in \cite{BrAn98} is incorrect. In particular, all former
conclusions made on the basis of the string Bethe equations remain valid.
