    now in the jd quadrant, until finally it settled in the former near 290° and moved from there to 270°. Aside from the general quadrant confusion with which we are already familiar, what should be emphasized here is the influence of the first localization. If that be at o° the attention is more or less predisposed to that direction and the movement perceived is usually continuous from that point. If, however, the primary localization be at 1800, the subsequent movement will be determined by that fact. (*•) Both sounds on the same side of the median plane, in all possible combinations, with intervals of 22^°. Number of experiments, 216. Three subjects.—The results of this series exhibit once more in a somewhat new form the con- fusion between the anterior and the posterior quadrants. Table VIII. Objective Combination.
