  Tunneling measurements have been carried out on slightly overdoped Bi2212
single crystals below and above the critical temperature by break-junctions and
in-plane point-contacts. An anomaly was found in the tunneling I(V)
characteristics. Analysis of the data shows that the anomaly is caused by the
superconducting condensate. In the extracted I(V) characteristics of the
condensate, the constant asymptotics points to the presence of
one-dimensionality in Bi2212. The anomaly found here puts additional
constraints on the final theory of high-T_c superconductivity.
