  The current status of the experimental knowledge of $\Bs$ meson physics is
reviewed. Results from LEP and CDF on the width difference $\dgs$ are
presented, the corresponding average is found to be in good agreement with the
present theoretical estimation. The $\Bs$ oscillations have not yet been
resolved, despite the progress recently achieved by SLD and ALEPH. The world
combination, including results from the LEP experiments, SLD and CDF, is
presented, together with the expected and observed lower limit on the $\Bs$
oscillation frequency. A tantalizing hint of an oscillation is observed around
$\dms\sim17 \psin$, near future results could increase the significance of this
hint.
