  We present intrinsic tunneling spectroscopy measurements on small
Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$ mesas. The tunnel conductance curves show both
sharp peaks at the superconducting gap voltage and broad humps representing the
$c$-axis pseudo-gap. The superconducting gap vanishes at $T_c$, while the
pseudo-gap exists well above $T_c$. Our observation implies that the
superconducting and pseudo-gaps represent different coexisting phenomena.
