The path integral of quantum gravity probes space-times with nontrivial topology and induces chiral symmetry breaking via an anomaly proportional to epsilon/sup ..mu..//sup ..nu..//sup rho//sup sigma/R/sup ..cap alpha..//sub ..beta..//sub ..mu..//sub ..nu../ R/sup ..beta..//sub b//sub rho//sub sigma/ in the divergence of the axial fermion number current. The corresponding classical instanton solution of Einstein's equations with cosmological term is found. The Euler-Poincare characteristic and ordinary instanton number are also discussed. (AIP)
