Two Guineas, net. OPINIONS OF THE PRESS. "In such times as this, a work at such a cost is as marvellous as the book is admirable. Parents of lads entering their teens-the doubting stage-should make a point of placing a copy in their hands."-Daily Mail, 26th January, 1920. "Really excellent little work."-Daily News, 26th Sept., 1902. "We welcome a new edition.... The appeal of the book is evidently one to common sense, and the success it has met is fully deserved. There'is a healthy lay atmosphere about Col. Turton's arguments which renders them we fancy peculiarly effective."-Pall Mall Gazette, 11th March, 1907. "It is difficult to know whether to admire most the logical precision with which he marshals his facts and enforces his conclusions, or the charming candour, and freshness of style, which make his book so readable."-Liverpool Daily Post, 14th March, 1907. "This is a new edition, thoroughly revised, of Lt.-Col. Turton's famous book .... We are specially struck with the detached manner in which he examines the case, he holds the scales evenly and is not rhetorical. Any one who has any power of reasoning at all can follow him clearly from start to finish."-Bristol Times and Mirror, 18th Feb., 1907. "It is a book for the hour, and needs to be circulated by thousands . straightforward, manly, and convincing."-Schoolmaster, 27th March, 1909. "This well-reasoned work appeals to common sense, it is candid and convincing."-Labour News, 16th Jan., 1925. Church of England. "Nothing need be added to our previous commendations of a work which has proved singularly serviceable, except to remark with appro- bation that its price has been lowered."-Church Times, 12th Dec., 1919. "We have repeatedly expressed our sense of the merit of Col. Turton's book."-Guardian, 9th Dec., 1908. "We must be content to emphasize our formerly expressed convic- tion of its exceptional clearness and value .... It deserves to be pointed out in more than a word, that every new edition is really such in a special degree. Col. Turton seems to devote the greater part of his leisure to the perfecting of his work, and never to be satisfied. Thus a thought is developed here, an argument strengthened there, and fresh illustrations are added as one edition succeeds another."-English Churchman, 12th Dec., 1912. "The book covers a wide range, is carefully and lucidly written, takes into account recent discussions and makes a deep impression on the mind."-Record. 16th Sept., 1926. "We give a hearty welcome to this revised edition. It is admirabl) suited for general use."-Churchman, Feb., 1909. "There is no padding and no unnecessary rhetoric. All the available space is filled with good solid reasoning, put in simple language which an intelligent artisan can follow as easily as an educated person."- Church Family Newspaper, 3rd Oct., 1902. "Few works of Christian apologetic have proved so useful. All the argument is lucid, and no questionable assumptions are intro- duced."-Commoiwealth, May, 1926. "This is a text book on Christian Evidence we would readily place in the hands of the lay worker as an essential part of his equipment." -Lay Reader, Dec., 1912. "We very heartily commend the new edition. We do not know of any other volume that places the facts of the Christian Faith in quite so clear a light."-Church Monthly, Feb., 1926. "This very excellent volume ... We strongly recommend this book to the Clergy for their own use and for lending to thoughtful and painstaking readers."-Church Union Gazette, Jan., 1901. "It is one of the best books of its class, readable, candid, convincing and thorough. It would be cheering news to hear that it had been widely read. The book will continue to make its way; and all Chris- tians will rejoice that it should do so."-Church Intelligencer, Oct., 1905. "This is the kind of book which strengthens believers and makes converts. It is one which should be placed within the reach of every lad at that period of his life when he begins to think for himself."- The (Church Lads) Brigade, Oct., 1905. "We have never met with any book which can be more confidently recommended."--Church Army Review, Dec., 1925. "No one who teaches in Sunday School or Bible Class should be without this volume."-Girls' Friendly Society Workers' Journal, Dec., 1925. "He is thoroughly up,to-date. The newest facts and discoveries are pressed into his service. The result is a book that can be read with equal pleasure and profit."-Irish Churchman, 8th Jan., 1920. "There is no book of this class known to The Canadian Teacher so complete and conclusive. Every teacher should have a copy."- Canadian Teacher, Toronto, Dec., 1920. "Its excellent index makes it extraordinarily easy to lay one's finger upon any specific point; we tested it, for instance, on this point, the contrast between the Incarnation and Hinqu incarnations. In a moment we have been able to find the gist of the whole matter accurately stated in a few words."-Calcutta Diocesan Record, Jan., 1913. Roman Catholic "The gallant Colonel is a non-Catholic, but the subject matter of his book is so admirable that hardly a Catholic periodical in the country has failed to commend it, and that with high and unqualified praise." -The Tablet, Oct., 1925.
