addition, omission, and the order of words, serve to attract the attention of the audience and do not allow it to flag, rousing it from time to time by some specially striking figure, while they derive something of their charm from their very resemblance to blemishes, just as a trace of bitterness in food will sometimes tickle the palate. But this result will only be obtained if figures are not excessive in number nor all of the same type or combined or closely packed, since economy in their use, no less than variety, will prevent the hearer being surfeited.
