A young clergyman is very apt to imagine that he will correlate together 20 to 100 propositions in every discourse--a theoretical conjecture never verified in fact. In _practice_, he will find that he will very rarely correlate more than ten propositions together, and he will correlate sub-propositions, citations, or illustrations to the respective propositions to which they belong. Instead of correlations, _he may unite his propositions together by analysis_. Each person will manage this matter as he finds most convenient to himself; or, if he desires to literally memorise his discourses, he can do so in the manner pointed out in learning sentences, or by two or three careful perusals. But, by one who speaks without notes is generally understood one who has only memorised his leading ideas, and it is always a judicious practice for a beginner to rehearse his leading topics and their amplifications in private, _that he may test his memory_, and then _become familiar_ with a procedure _in private_ in order to be sure to be _perfect in it before the public_. This private discipline is all the more necessary in the early stages of extempore speaking--if the speaker is at all troubled by nervous anxieties or mind-wandering. Suppose a teacher of the Art of Expression has studied Moses True Brown's [see his Synthetic Philosophy of Expression] reduction of Delsarte's Nine Laws of Gesture to Brown's One Law of Correspondence--and suppose this teacher wishes to explain to his class, or to an audience, how Mr. Brown proceeded. If he desires to do this without notes, he must memorise the order of those Nine Laws; they are abstractly stated and difficult to correlate, but it can be done. The Laws are as follows:-- Motion, Velocity, Direction or Extension, Re-action, Form, Personality, Opposition of Agents, Priority, or Sequence, Rhythm. The teacher must correlate these heads or topics of his discourse together, and so memorise his correlations that he can recall the series in the exact order. Perhaps he may proceed thus: MOTION. [Rate of motion.] VELOCITY. [Relation of motion to time and _space_--.] DIRECTION or Extension. [Direction reversed.] RE-ACTION. [Mould of Action.] FORM. [Form of the Human.] PERSONALITY. [Its extremes.] OPPOSITION OF AGENTS. [First opponent.] PRIORITY or Sequence. [Periodicity of Sequence.] RHYTHM. Knowing these Nine Laws in the above _order_, he can discuss them one after the other. When he has finished his explanation of the reduction of the three Forms of Motion [Concentric, Poise, and Eccentric] to the Law of Correspondence, he can proceed to the consideration of the sub-topics under Velocity, and so on. When he has fixed the other of his topics in mind, he has a mental chart or map to guide him in his exposition, and similarly in other cases. EXERCISE.
