5. Division of the Suhject. We have then to inquire, on what do economy of Lime and fullness of meaning depend ? Economy of Lime obviously depends on (1) the length of words, anl (2) their number. Fullness of meaning depends on (1) the familiarity, (2) the inclusion, (3) the implication, (4) the position of words, and (5) the relation of each word to the idea as a whole. It will be observed that length, familiarity, inclusion, and implication, are properties of single words, while their number, position and relation have reference to words in combination. Since these are all the properties possessed by words either singly or in combination affecting either time or truth, it is plain that we shall most easily and accu¬rately discover the requirements of expression by finding in what manner each property is related to the general law of style, the economy of mental power. We proceed, therefore, to consider

(1) DICTION, or the Choice of Words, and

(2) SENTENCES, or the Combination of Words.
