We have been delighted with the perusal of this book, and consider it one of the most instructive as well as one of the most amusing of autobiographies. The ruling feature of the work is candor--a candor of the rarest and noblest description. The author has not scrupled, or even hesitated, in a single instance to declare, without prevarication, the truth and the whole truth, however little redounding to his own credit. Nor in the details so frankly laid before the eye of the public, are the many--very many other excellent qualities less manifest, which have exalted the autobiographer to so enviable a station in the opinions of his fellow-citizens. In the whole private and public course of Mr. Mathew Carey, from that chivalrous Essay against Duelling, of which he has rendered so amusing an account in the commencement of his "Life," to the more important yet equally Quixottic publication of the Olive Branch, the strictest scrutiny can detect nothing derogatory to the character of "the noblest work of God, an honest man." His energy, his high-mindedness, and his indomitable perseverance, will force themselves upon the most casual observer. It is not surprising that, with qualifications so well adapted for success in life, Mr. C. should have been enabled finally to set at defiance the innumerable obstacles which obstructed his path. Indeed, although few men have labored under greater incidental disadvantages, very few have been better prepared to overcome them by both moral and physical constitution. There is much in these Memoirs of Mr. Carey, which will bring to the mind of the reader Benjamin Franklin, his shrewdness, his difficulties, and his indefatigability. It is therefore almost unnecessary to add, that apart from its other merits, the Autobiography now before us has all the value so unequivocally due to _good example_. Its perusal cannot well fail of having a salutary effect upon those who struggle with adversity--of imparting a salutary strength to all who grow feeble under the pressure of the innumerable harassing cares which encumber and weigh so ponderously upon the "man of the world." It may, indeed, if rightly considered, have a still more beneficial influence. It may incite to good deeds. It may induce a love of our fellow-men, in many bosoms hitherto self-hardened against the urgent demands of philanthropy. What so likely to bring about a kindly spirit in any human heart as the contemplation of a kindly spirit in others?
