  We construct solutions of analogues of the nonstationary Schr\"odinger
equation corresponding to the polynomial isomonodromic Hamiltonian Garnier
system with two degrees of freedom. This solutions are obtained from solutions
of systems of linear ordinary differential equations whose compatibility
condition is the Garnier system. This solutions upto explicit transform also
satisfy the Belavin --- Polyakov --- Zamolodchikov equations with four time
variables and two space variables.
