The _North American Review_ for the July quarter is in many respects characteristic. Six months after every Review published in Great Britain had had its paper on Southey, and when the subject is quite worn out, the _North American_ furnishes us with a leading article upon it, in which there is neither an original thought nor a new combination of thoughts that are old. Colton's _Public Economy_ gives a title to an article, in which the book is treated superciliously, and some ideas by Henry C. Carey are presented as the original speculations of the reviewer. It is deserving of remark that the _Past and Present_, and more recent works of Mr. Carey, which among thinking men throughout the world have commanded more attention than any other writings in political philosophy during the last five years, have never been even referred to in this periodical, which arrogates to itself the leadership of American literature. The eighth article of the number is on the Unity of the Human Race, and considering the place it occupies in the _North American Review_, for July, 1851, it is contemptible. It is based on five publications made in England previous to 1847, and ignores all the research and discussion since that time, notwithstanding the facts that the subject never was so amply, so profoundly, or so luminously discussed as during the last year--that the very writers referred to in the article have for the chief part published their most important treatises upon it since 1847--that within six months its literature has received large accessions in France, Germany, and Italy,--and that in _our own country_, of whose intellectual advancement this Review is bound to give some sort of an index, the four years since Latham's "Present State and Recent Progress of Ethnological Philosophy" appeared, have furnished important works by Albert Gallatin, Mr. Hale of the Exploring Expedition, the Rev. Dr. Bachman, the Rev. Dr. Smyth, and several others, all of which should have been considered in any new, especially in any American _resume_ of the discussion. Johnston's _Notes on North America_ is treated with a spleen excited by the author's refusal to recognize the greatness assumed for certain persons connected with Harvard College, and Mr. Bowen is weak enough to say, or to permit a contributor to say, "we _understand_(!) Mr. Johnston has a high reputation," &c. Pish! And what does the reader suppose is the theme--the fresh, before unheard-of theme--of another paper? what new star, in the heaven of mind, demanded most the exploration and illustration of the _North American Review_, for this July quarter, in 1851? The best guesser of riddles would not in fifty years hit upon Mr. Gilfillan's book of rigmarole entitled _The Bards of the Bible_, but this performance, which had been criticised in every other quarterly, monthly, weekly, and daily, in the English language, that would descend to it, crowds out the subjects of "great
