GENTLEMEN:--In reply to your communication, in reference to the “Library of Christian Knowledge,” edited by the Rev. Herman Hooker, I take pleasure in saying, that I regard it as one of the most valuable and substantial publications of the present day. The original works from the pen of the talented editor, I regard, as among the ablest productions of modern times; and his excellent taste has led him to select from the English writers, some of the richest stores of theological truth. I rejoice to know, that this work is to be continued, and I wish it all success. In my view, both the editor and the publisher, are conferring upon the country a rich blessing in this publication. JOHN A. CLARK, _Rector of St. Andrew’s Church, Philadelphia_. _Princeton, N. J. Feb. 18, 1837._ The “Library of Christian Knowledge,” edited by the Rev. Herman Hooker, and published by Marshall & Co. in a series of small volumes, is upon a plan well calculated to be useful. The publication of religious treatises, characterised by sound evangelical sentiments, and animated with the spirit of genuine piety, cannot but be highly beneficial to the Christian community. The five volumes of this series which have been already published, meet with my cordial approbation; and if these may be considered a fair specimen of those which are to follow, the work may be safely recommended, as furnishing materials for a valuable CHRISTIAN LIBRARY. A. ALEXANDER, _Prof. of Didactic Theology, in the Theological Seminary, Princeton_. _Princeton, Feb. 16, 1837._ MESSRS. WM. MARSHALL & CO. GENTLEMEN:--I have attended with much interest to the volumes of the “Library of Christian Knowledge,” as they have successively appeared; and exceedingly rejoice, both in the plan of the work, and thus far, in its execution. I have a high opinion of the piety and the talents of the Rev. Mr. HOOKER, the editor, and consider him as well qualified to conduct a work of this nature. If the future volumes should bear a stamp similar to that of those which have hitherto appeared, I shall be glad--and every friend of genuine Christianity, I should hope, would be glad--to see them universally circulated. Wishing you, and the excellent editor, every encouragement in this publication, I am, gentlemen, respectfully yours, SAMUEL MILLER, _Professor of Eccl. History in the Theological Seminary, Princeton_. _Philadelphia, March 2, 1837._ MESSRS. WM. MARSHALL & CO.
