A Satirical Tale of the Times, with other Poems, by the Author of Pelham, &c._ J. & J. Harper: New-York: pp. 308. This production furnishes one of the most remarkable instances to be found in the history of literature, of the wide difference between notoriety and merit. No work ever came from the press whose anticipated excellence was more loudly proclaimed, and none, we are persuaded, ever more disappointed high-wrought expectation.
