We have measured the negative magnetoresistance of an anisotropic two-dimensional electron gas at low temperatures. We report the first observation of the predicted anisotropy in the strength of the logarithmic terms in the weak localization theory for a system with effective mass and scattering time anisotropy. The results provide the first parameter-free test of the scaling theory of localization.
