  We prove that the Hatcher-Quinn and Wall invariants of a self-transverse
immersion $f\co N^n\imm M^{2n}$ coincide. That is, we construct an isomorphism
between their target groups which carries one onto the other. We also employ
methods of normal bordism theory to investigate the Hatcher-Quinn invariant of
an immersion $f\co N^n\imm M^{2n-1}$.
