This paper describes recent developments in Heavy Flavour physics at LEP,
focusing on a new result from the ALEPH Collaboration on the search for flavour
oscillations of the Bs meson. The impact of this analysis on the world
combination and the resulting limit on the Bs oscillation frequency are
discussed.Comment: 6 pages, 7 Encapsulated Postscript figures, uses pennames.sty, to be
