  In 1966, H. Widom proved an asymptotic formula for the distribution of
eigenvalues of the $N\times N$ truncated Hilbert matrix for large values of
$N$. In this paper, we extend this formula to Hankel matrices with symbols in
the class of piece-wise continuous functions on the unit circle. Furthermore,
we show that the distribution of the eigenvalues is independent of the choice
of truncation (e.g. square or triangular truncation).
