Measurements are presented of electrical potential values on single crystals of TTF-TCNQ which show an extraordinary apparent conductivity maximum near 70 K. The observed voltages in these anisotropic crystals are shown to be unusually sensitive to the points at which electrical contact is made. Our anomalous apparent conductivities can be understood in terms of the strong temperature dependence of the electrical anisotropy which is found, through measurements on several samples, to peak near 70 K.
