THOSE who are unfamiliar with the life of Princeton Theological Seminary and desire to learn something of the nature and the early history of the “Conferences” held in the “Oratory” of the Seminary may be referred to the Life of Archibald Alexander by his son, James W. Alexander, pp. 420 ff; the Life of Samuel Miller by his son, Samuel Miller, vol. ii, p. 400; and the Life of Charles Hodge by his son, A. A. Hodge, pp. 453 ff; with the last of which may be compared the Preface to Conference Addresses by Charles Hodge.
