Arrangement is the ordering and distribution of the matter, making clear the place to which each thing is to be assigned. Style is the adaptation of suitable words and sentences to the matter devised. Memory is the firm retention in the mind of the matter, words, and arrangement. Delivery is the graceful regulation of voice, countenance, and gesture.
