The list of works prefixed to the article here entitled "Distinctive Types of Christianity," as it appeared in the Westminster Review, and the opening sentence referring to them, have been accidentally omitted. Two or three of the papers belong to the author's earlier years, but are inserted here equally on account of their eminent ability, their special timeliness, and their striking adaptation to the general purpose of the work; namely, to throw light on the true nature of Christianity. They will also be new to most of those whom they now reach. The last paper in the volume is one of the first its writer published, in his comparative youth. We shall be disappointed if the benignant wisdom and moral fidelity of its catholic lessons do not secure a sympathetic response in many a quarter once closed against such appeals. In selecting from Mr. Martineau's numerous invaluable articles, not already published in book-form, the contents of the present work, the rule has not been so much to choose the ablest productions, as to take those best fitted to meet the wants of the time, by diffusing among ministers, students of divinity, and the cultivated laity a knowledge of the most advanced theological and religious thought yet attained. We regret that the necessary limits of the volume exclude several of the author's most instructive and inspiring essays; particularly the magnificent one in the National Review upon "Newman, Coleridge, and Carlyle"; also the one upon "Lessing as a Theologian."
