1. This work grew from a study of the conditions under which a Gaussian stochastic process has a "smooth" local time for almost all sample functions [l]-[4]. It is shown here that the main calculation in our previous work involves a property of Gaussian processes which is of independent interest—local nondeterminism. Let X(t\ — oo < t < oo, be a Gaussian process with mean 0, and J an open interval on the t-axis. Suppose that
