1. Outline the chapter, in the form of a list of laws and sub-laws.
2. Review the instances of learning cited in Chapters XIII-XV, and examine whether they are covered and sufficiently accounted for by the general laws given in the present chapter.
3. Draw diagrams, like those given in this chapter, for the simpler cases, at least, that you have considered in question 2.
4. Show that response by analogy is important in the development of language. Consider metaphor, for example, and slang, and the using of an old word in a new sense (as in the case of 'rail-road').
