Comment on the paper ``Bound States in the One-dimensional Hubbard   Model''
  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.
