RUSSELL’S LETTERS, in two volumes, exhibit, in a chaste and intelligible style, the most important features in the plan of redemption and of Christian duty. The letters were actually addressed to an individual, previous to publication, for this purpose; a circumstance which has been justly thought calculated to ensure for them a peculiarly _practical_ character. Those who desire clear and profitable instruction upon the subject of religion, from an original, but judicious, well balanced and pious mind, will not be disappointed in perusing Russell’s Letters.--_Episcopal Recorder._ * * * * * The Rev. Mr. Boardman thus speaks, in his Introductory Essay, of the author and his works:--“The name of Dr. Russell is familiar to the friends of Christ throughout the united kingdom--and his eminent piety, talents, and usefulness have placed him in the front rank of those celebrated divines, who are justly regarded as an ornament of his country, and an invaluable blessing to the age. His various writings are held in high estimation on the other side of the Atlantic, and it is not a little surprising that the extensive circulation which they have had there, has not led to an earlier republication of them in the United States. This series of Letters is perhaps the most interesting of all his works. Those who may peruse it, will not deem the opinion an extravagant one, that it will hereafter rank with the standard volumes on practical religion, which find a place in every Christian Library.” * * * * * POPULAR INFIDELITY. By the Rev. Herman Hooker, M. A. Vol. 5, Library of Christian Knowledge. When, in our first volume, we took notice of the Rev. Mr. Hooker’s “Portion of the Soul,” we expressed the hope, that, from the golden vein thus opened, we should have other and richer specimens--and we ventured to predict, that, the more it should be worked, the finer would be the ingot. We are proud to record our predictions. In the present volume our most golden dreams are more than realized. It is a book of an age; and we will say of a better age--“specimen melioris ævi.” It shall be taken down, in the dark, from the same shelf on which the writings of South, Taylor, Barrow, Boyle, Bates, and How, repose in glory unsurpassed of earth; and shall be replaced again, when read, by the most ardent lover of them all, as worthy of the high companionship. We know what we have said, and we challenge doubters to the proof.
