Query: Comment on "Superconducting order parameter in partially substituted
  Bi2212 single crystals as measured by the tunneling effect"   In this Comment, we explain the reason for the discrepancy between two sets
of tunneling data obtained on Ni- and Zn-doped Bi2212 single crystals
(presented in H. Hancotte et al., Phys. Rev. B 55, R3410 (1997) and A.
Mourachkine, to be published in J. of Superconductivity, cond-mat/9902355).
