The first place here belongs to the psychologist, who is building up the already extensive edifice of knowledge concerning the real nature of the child and the contents and growth of the youthful mind, and to the practical teacher who is in touch with that knowledge and can bring it to the test of actual experience. Before considering what drugs are to be administered we must consider the nature of the organism they are to be thrust into.

He is without the pubertal expansion which fills out the mind with new personal and altruistic impulses and transforms it with emotion that is often dazzling and sometimes distorting; and he has not yet absorbed, or even gained the power of absorbing, all those beliefs, opinions, and mental attitudes which the race has slowly acquired and transmitted as the traditional outcome of its experiences.
The intellectual processes of children, the attitude and contents of the child's mind, have been explored during recent years with a care and detail that have never been brought to that study before.
