"Thoughts that voluntary move
Harmonious numbers."

As there are certain sounds that excite certain movements, and the
song and dance go together, so there are, no doubt, certain thoughts
that lead to certain tones of voice, or modulations of sound, and change
"the words of Mercury into the songs of Apollo." There is a striking
instance of this adaptation of the movement of sound and rhythm to the
subject, in Spenser's description of the Satyrs accompanying Una to the
cave of Sylvanus.

"So from the ground she fearless doth arise
And walketh forth without suspect of crime.
They, all as glad as birds of joyous prime,
Thence lead her forth, about her dancing round,
Shouting and singing all a shepherd's rhyme;
And with green branches strewing all the ground,
Do worship her as queen with olive garland crown'd.

And all the way their merry pipes they sound,
That all the woods and doubled echoes ring;
And with their horned feet do wear the ground,
Leaping like wanton kids in pleasant spring;
So towards old Sylvanus they her bring,
Who with the noise awaked, cometh out."
_Faery Queen_, b. i. c. vi.

On the contrary, there is nothing either musical or natural in the
ordinary construction of language. It is a thing altogether arbitrary
