CINCINNATI, Nov. 12

  THE NORTH AMERICAN REVIEW, Oct. No., has published an article on Uncle Tom's Cabin and Slavery, which is exceedingly painful to one's moral sensibilities, and his intellectual common-sense. We are ready to look at the title page, and examine whether the place of publication is not St. Petersburg or Vienna, instead of Boston. It is too late in the day, we ween, to say that slavery is not a violation of human rights, or that it is at all a parallel case to the condition of minors under their parents and guardians, or to suggest that there might be some system of modified slavery introduced into the Northern states, to restrain the ignorant, and especially the emigrant population, and make them work better and behave more orderly!! If this writer is so far in the dark ages that he has not found out, to use the words of De Quincey, that "man is, as he is treated," we would recommend that he be put at school, under Mr. Peake, at the New York Five Points, or on the United States sloop-of-war Germantown, where that fact will be elucidated to his understanding. An obstinate will and the stiffest chevaux de frize of prejudices must constitute that man's mental and moral furniture . . .
