Mr. Latrobe is connected with a lineage of missionaries. He belongs to an English family long and honorably distinguished by their exertions in the cause of Christianity. His former work, "The Alpenstock," we have not seen--but the London Quarterly Review calls it "a pleasing and useful manual for travellers in Switzerland." The present volumes (dedicated to Washington Irving, whom Mr. L. accompanied in a late tour through the Prairies,) consist of thirty-seven letters addressed to F. B. Latrobe, a younger brother of the author. They form, upon the whole, one of the most instructive and amusing books we have perused for years. By no means blind to our faults, to our foibles, or to our political difficulties, Mr. Latrobe has travelled from Dan to Beersheba without finding all barren. His observations are not confined to some one or two subjects, engrossing his attention to the exclusion, or to the imperfect examination, of all others. His wanderings among us have been apparently guided by a spirit of frank and liberal curiosity; and he deserves the good will of all Americans, (as he has most assuredly secured their esteem) by viewing us, not with a merely English eye, but with the comprehensive glance of a citizen of the world. To speak in detail of a work so subdivided as "The Rambler in North America," would occupy too much of our time. We can, of course, only touch, in general terms, upon its merits and demerits. The latter, we can assure our readers, are few indeed. One instance, nevertheless, of what must be considered false inference from data undeniably correct, is brought to bear so pointedly against our social and political principles, and is, at the same time, so plausible in itself, and so convincingly worded, as to demand a sentence or two of comment. We quote the passage in full, the more willingly, as we perceive it dwelt upon with much emphasis, by the London Quarterly Review.
