Reflectivities of silver and gold as measured by Bennett and Ashley are compared to the equations of Dingle for free electrons, including the anomalous skin effect. At a wavelength of about 5 &mgr;, the measurements are consistent with Dingle's equations with about half of the electrons specularly reflected from the metal surface. At lower wavelengths the measured reflectivities are lower than the theoretical ones; the origin of this deviation is not clear.
