Seeking to play the game according to the rules, I am forced to two conclusions: First, that I have little to say on the grouping of subjects and, secondly, that the typographical arrangement requires some explanation -perhaps even justification.

These pages are in many ways comparable to the instructor's preliminary talk or a blackboard outline before the class takes up co-related subjects in detail.
