Thus, in regard to ornaments,--it would be unjust to conclude, that, because they were at first arbitrarily contrived, they are therefore undeserving of our attention; on the contrary, he who neglects the cultivation of those ornaments acts contrary to nature and reason. As life would be imperfect without its highest ornaments, the Arts, so these arts themselves would be imperfect without _their_ ornaments. Though we by no means ought to rank with these positive and substantial beauties, yet it must be allowed that a knowledge of both is essentially requisite towards forming a complete, whole, and perfect taste. It is in reality from their ornaments that arts receive their peculiar character and complexion; we may add, that in them we find the characteristical mark of a national taste; as, by throwing up a feather in the air, we know which way the wind blows, better than by a more heavy matter. The striking distinction between the works of the Roman, Bolognian, and Venetian schools consists more in that general effect which is produced by colours than in the more profound excellencies of the art; at least it is from thence that each is distinguished and known at first sight. Thus it is the ornaments rather than the proportions of architecture which at the first glance distinguish the different orders from each other; the Doric is known by its triglyphs, the Ionic by its volutes, and the Corinthian by its acanthus. What distinguishes oratory from a cold narration is a more liberal, though chaste, use of those ornaments which go under the name of figurative and metaphorical expressions; and poetry distinguishes itself from oratory by words and expressions still more ardent and glowing. What separates and distinguishes poetry is more particularly the ornament of _verse_; it is this which gives it its character, and is an essential without which it cannot exist. Custom has appropriated different metre to different kinds of composition, in which the world is not perfectly agreed. In England the dispute is not yet settled, which is to be preferred, rhyme or blank verse. But however we disagree about what these metrical ornaments shall be, that some metre is essentially necessary is universally acknowledged.
