A Poem, on the joyful news of the Rev. Mr. Whitefield's visit to Boston : Dedicated to all the true friends of such "an exemplary Christian, fine gentleman and accomplish'd orator, who has discover'd in some late sermons such a deep insight into human nature, which abounded with fine characters, curiously pourtray'd, and his great skill in moral penciling, which with his manner of life, he's justly gain'd this character.
