III. This part of the work was an attempt to estimate the average time-interval in which feeling-tones develop, and what influences other feelings given simultaneously or immediately beforehand have upon the time-development of the feeling-tone in question. Will certain feelings hasten and others retard a third feeling whose character remains unchanged when it crosses the limen of awareness? Does the feeling, for example, aroused by contact with a soft, soothing, yielding tactual surface, put one in such a state that he will more or less quickly obtain pleasure from the visual impression coming from a soft rich red color? What effect will a feeling already aroused by a low tone have upon the time development of the feeling one gets from looking at a deep green color? Are there, again, pleasant feelings of certain dimensions which will be hastened by other feelings, and still others which, by the same means, will be retarded? If so, under what general principle do they seem to fall? Here the time-development of a certain feeling-tone is taken when there are no other influencing factors. Then the comparison of this rate is made with the later reported time-interval when that feeling, again aroused, has been immediately preceded or accompanied by a feeling-tone from another source of stimulation. Here also feelings for colors presented in a frame, without any special suggestion of form in connection with them, were in like manner compared as to their time-development with the affective states arising from those same colors presented again enclosed in cardboard frames of special character. Some of these forms were very pleasing, such as upright ovals, small circles, etc., while others, frames cut purposely into irregular shapes, were to most observers decidedly unpleasant. * * * * * IV. Here complex feeling-states were in question, and evidence was sought as to how much could be detected here that would tend to substantiate or to call in question what seemed to be the fundamental principles of feeling-relations where the states are very simple. Further complications, such as three and even more stimulations at once, were tested. After this, feelings aroused by looking at pictures of statues were studied and described as accurately as possible. "Perry Pictures" were used. _Dying Alexander_, _Venus of Milo_, the _Dying Gladiator_, the _Laocoön_ group, and _Apollo Belvedere_, served to introduce sufficient variety. Then copies of these same statues were cut out from the card and presented to the subject with the same colors before studied used as background. These were allowed to play their part in the feeling aroused therefrom.
