T. (Giessen, 1908 sqq.). He has also edited Tertullian's De pnitentia et de pudicitia (Freiburg, 1891) and De prscriptione hreticorum (1892), as well as Origen's commentary on St. John (Leipsic, 1903), while in 1900 he founded the Zeitschrift für die neutestamentliche Wissenschaft, of which he has since been the editor. He has translated E. Hatch's Greek Ideas and Usages, their Influence upon the Christian Church (London, 1890) under the title Griechentum und Christentum (Freiburg, 1892) and the Armenian version of the sixth and seventh books of the church history of Eusebius (Leipsic, 1902).
