We report observations of characteristic reservoir oscillations induced by persistent circulation in saturated /sup 4/He films for several different geometries. The shape of the oscillation structure appears to be in qualitative agreement with the predictions of Campbell. Within the constraints imposed by theoretical approximations and uncertainties in the experimental parameters, the quantitative agreement is satisfactory.
