I. SPECIAL FUNCTIONS WHICH HAVE NOT BEEN LONG STUDIED

There are various mental functions which are now thought to be largely special, which have not yet been studied sufficiently to warrant extended discussion of each, yet which merit notice as such if for no other reason than that attention should be directed to the desirability of studying their place in intellectual organization. Some of these, like chess-playing, will not be discussed here, as they are at present but remotely connected with prescribed education. We shall, therefore, comment upon but some of these, giving such facts and theories as are available in the case of each.
