The Libeller's Self-Reproof[1]

      Rash mortal, and slanderous poet, thy name      Shall no longer appear in the records of Fame;      Dost not know that old Mansfield, who writes like the Bible,      Says, the more 'tis a truth, sir, the more 'tis a libel!

These are rhymes of dubious authenticity.-Lang.
