We use this result, in conjunction with heavy-quark symmetry, to extract $|V_{cb}|$ from the experimentally measured $\bar B\to D^*l\barν\,$\ differential decay width.3 pages, uuencoded compressed postscript file, to appear in the Proceedings of the International Europhysics Conference on High Energy Physics, Marseille, July 22-28, 1993.
