GRAHAM'S MAGAZINE, for February, has come to hand. The Frontispiece is, to us, an enigma. "Black Letters; or, Tom-Foolery in Literature," we have perused with attention, regret, and (we would add) disgust. It is the most unjust, the most ungenerous, and the least refined review of the world-renowned book we have ever read. Large prospects may sometimes be seen through small openings—so the expression, "we hate this niggerism," is the solution of the whole matter. There is something most absurd in the assertion that, as a means of abolition, Uncle Tom is "a mistake" and "a failure." Is Graham in his sober senses? He must pardon us if we presume to doubt it.
