We apply recently developed techniques to give an exact nonperturbative solution of the two matrix realization of the Ising model coupled to 2D lattice gravity. We demonstrate that the Ising model is different from multicritical matter. We conjecture that multicritical matter is described by certain non-unitary minimal models. © 1990.
