Let P(n), P be probabilities, and F, F- be collections of real functions. Simple conditions are derived under which the simple convergence of integral f(x)P(n)(dx) to integral f(x)P(dx) for every f in F- implies uniform convergence over F: sup(f is-an-element-of F) \ integral f(x)P(n) (dx) - integral f(x)P(dx)\ converges to 0. Several examples are discussed, some historical and some new.
