and inadequate to raise the Reader to a height of desirable excitement, then, (unless the Poet's choice of his metre has been grossly injudicious) in the feelings of pleasure which the Reader has been accustomed to connect with metre in general, and in the feeling, whether chearful or melancholy, which he has been accustomed to connect with that particular movement of metre, there will be found something which will greatly contribute to impart passion to the words, and to effect the complex end which the Poet proposes to himself. If I had undertaken a systematic defence of the theory upon which these poems are written, it would have been my duty to develope the various causes upon which the pleasure received from metrical language depends. Among the chief of these causes is to be reckoned a principle which must be well known to those who have made any of the Arts the object of accurate reflection; I mean the pleasure which the mind derives from the perception of similitude in dissimilitude. This principle is the great spring of the activity of our minds and their chief feeder. From this principle the direction of the sexual appetite, and all the passions connected with it take their origin: It is the life of our ordinary conversation; and upon the accuracy with which similitude in dissimilitude, and dissimilitude in similitude are perceived, depend our taste and our moral feelings. It would not have been a useless employment to have applied this principle to the consideration of metre, and to have shewn that metre is hence enabled to afford much pleasure, and to have pointed out in what manner that pleasure is produced. But my limits will not permit me to enter upon this subject, and I must content myself with a general summary.
