Professor Holtzmann in a brief introduction of seventeen pages sketches the history and literature of New Testament criticism. The book is divided into two parts, the first treating the subject in a general way, the second entering into its several details. In the first part the author presents us with a history of the text and of its traditions, explaining the causes of the alterations that were introduced either unintentionally or by mistake; he reviews the critical apparatus for text-revision and also the history of the printed and revised editions up to the present attempt at emendation. Then a history of the canon is given, from the oldest Christian literature down to the radical criticisms of the present time. In the second and special part we find a careful compilation of all the criticisms concerning the single books and epistles of the New Testament. The first chapter treats of St. Paul’s epistles to the Thessalonians, Galatians, Corinthians, Romans, to Philemon, the Colossians, Ephesians, Philippians, the pastoral epistles; further, the epistle to the Hebrews, which is non-Paulinian, the two epistles of St. Peter, the epistle of St. Jude, and that of St. James. The second chapter introduces us into the historical books of the synoptic gospels and the Acts, where, in a brief review of fifty-seven pages, we find the same data presented which are more fully explained in another publication of our author, reviewed in _The Monist_, Vol II, No. 2. A new period in the development of Christian literature begins with all those writings which go under the name of St. John. A discussion of these books is contained in the third chapter, which treats of the apocalypse, the fourth gospel, and St. John’s epistles. Not the least interest attaches to the fourth chapter, the subject of which is the vast domain of the apocryphal books of the New Testament, the number of which has, of late, been greatly increased by several new discoveries. The subject divides itself naturally into apocryphal gospels (Chap. II), apocryphical stories about the lives and deeds of the apostles (Chap. III), apocryphical epistles (Chap. IV), and apocryphical apocalypses (Chap. V). κρς. SAMMLUNG VON POPULÄR-WISSENSCHAFTLICHEN VORTRÄGEN ÜBER DEN BAU UND DIE LEISTUNGEN DES GEHIRNS. By Professor _Theodor Meynert_.
