As I search the archives of my memory I seem to discern six types or methods which divide themselves from one another with measurable distinctness. There is the type magisterial or imperative; the type laconic or sententious; the type conversational or homely; the type refined or artificial, smelling of the lamp, verging at times upon preciosity or euphuism; the demonstrative or persuasive; and finally the type tonsorial or agglutinative, so called from the shears and the pastepot which are its implements and emblem.
