Original September 1, 1857 three-page autograph letter signed “A. H. Clough” by English poet Arthur Hugh Clough (1819–1861), addressed to American poet James Russell Lowell (1819–1891), founding editor of The Atlantic Monthly. Writing from the Council Office in London, Clough introduces Dr. and Mrs. Bodichon, discusses their anticipated American visit, recalls meeting Francis H. Underwood at Lowell's Elmwood home, and expresses concern about Charles Eliot Norton's return voyage. An excellent example of transatlantic literary correspondence connecting prominent British and American intellectuals during the founding year of The Atlantic Monthly; Clough's correspondence with Lowell concerning the magazine and his poetry is independently documented. The original bifolium measures approximately 7" × 4.5" folded, with three handwritten pages, original folds, age toning, minor edge wear, and substantial old adhesive or mounting remnants along the bottom of the final page.
