346 of the scale; and we may find how many times a smaller difference is contained in a larger. But to measure the difference is not necessarily to measure the sensations that differ.

This connects with a preceding article (Bd. II, pp. 164 ff.) on aesthetic contrasts. In the case of the sublime, contrast is especially significant. Kant maintains (Critique of Judgment, sect. 27) that in the apprehension of the sublime, imagination and reason come into conflict, since the sublime object surpasses the capacity of the imagination, but conforms to the reason. While he finds this contrast a subjective one, the writer tries to show that in all cases, but especially in those of moral sublimity, it has an objective reality. Such a conflict as Kant finds, while possibly existent elsewhere, certainly does not appear in the cases of moral sublimity, for in such cases the imagination has no incentive to attempt aesthetic appreciation, and thus to run counter to reason. Rather do our sympathy on the one hand, and our reason on the other, arouse conflicting feelings, which represent and reproduce the objective contrast.

1. The effect of fore -knowledge upon repetition-times. Conclusion reached was that, "as the range of possible words decreases in extent, as the, subject's expectation is more and more definite, the time needed to repeat the word becomes shorter." 2. A novel optical illusion. Investigation of the bands produced by moving a horizontal rod up or down before a rotating disk composed of two rectors differing in color and shade. 3. Accessory apparatus for accurate time-measurements. (a) For control of the chromoscope. (b) For timing the rotation of disks, (c) For a way of color-mixing. 4. The psycho-physic series and the time-sense. Experiment consisted in assigning time-intervals given on the metronome to different classes. Results grouped themselves approximately under the psycho-physic law. 5. The psycho-physic series and the motor sense. Movements of the forearm within the limits 5 to 190 millimeters were assigned to six classes. Results approximated an arithmetic rather than a geometric series. 6. The interference of mental processes — a preliminary survey. The problem is the power of carrying on two mental processes at once. Motor processes interfere with motor processes; and the time of performing certain mental processes (reading sentences, words, etc.) is increased by motor processes.
