Note 15 — Chapter VI · OF RHYME.
Reading edition
It is a curious confirmation of my theory about the Cockney grounds for objection to this rhyme, that the author of a handbook who condemns "heart" and "art" as a rhyme, fails to see any fault in "dawn" and "morn," or in "applaud" and "aboard" as rhymes. Of course, where the "h" is mute as in "hour," it cannot rhyme with the simple vowel as in "our," sound being the test of rhyme, and the ear the only judge. A "rhyme to the eye" is an impossibility.
