The resistivity of several YBa2Cu307 _ x crystals in the ab plane and along the direction of the с axis has been measured. The large anisotropy and the small transverse critical current are probably evidence of a significant inhomogeneity of the crystals along the direction of the с axis. This inhomogeneity gives rise to multiple Josephson junctions.
