Resistivity pxx and Hall resistivity pxy were measured as functions of the magnetic field, temperature, and the metal volume fraction x, on a series of percolating Ni-Si02 granular films. At 5 K, the data for the metallic samples were fitted to power law dependencies of the forms, pxx ~ [(x -xc)/xc]
