  The contributions of $s-$channel Higgs in $l^+ l^- \rightarrow q \bar{q}$
processes in the general lepton collider ($l^+ l^-$ collider) within Standard
Model is studied. A new idea to extract the contribution by using the data from
both electron and future heavy-lepton colliders at same center-of-mass energy
is proposed. Deviations due to the $s-$channel Higgs contributions are analysed
and discussed for the heavy-quark final states by using the total
cross-section, forward-backward asymmetry and its ratio. It is shown that
significant deviations are expected for the top quark final state.
