We have measured the difference in the density of states (dos) in Bi2Sr2Ca1Cu2O8 (2212) between the c-axis and the ab-plane in our earlier experiments. Anisotropic properties within the ab-plane are not well established experimentally yet. We have performed tunneling experiments in three different directions within the ab-plane on the same piece of sample. Crystal orientation was determined by X-ray diffraction. The gap values and also the dos are significantly different in these directions.
