We may climb into the thin and cold realm of pure geometry and lifeless science, or sink into that of sensation. Between these extremes is the equator of life, of thought, or spirit, or poetry,--a narrow belt.
The word "Verse" is used here as the term most convenient for expressing, and without pedantry, all that is involved in the consideration of rhythm, rhyme, meter, and versification... the subject is exceedingly simple; one tenth of it, possibly may be called ethical; nine tenths, however, appertains to the mathematics.

For Eros is older than Saturn or Jove;
Never was poet, of late or of yore,
Who was not tremulous with love-lore.
