Query: A Note on Ward's Chiral Model   A one parameter generalization of Ward's chiral model in 2+1 dimensions is
given. Like the original model the present one is integrable and possesses a
positive-definite and conserved energy and $y$-momentum. The details of the
scattering depend on the value of the parameter of the generalisation.
