The very early date to which this homily is now assigned makes its slightest allusions to the New-Testament canon of very great importance. I have ventured to indicate a few such, even where they may be mere allusions, not textual quotations: as, e.g., on p.517, at notes 20 and 22, slight indications of a reference to the Second Epistle of St. Peter and to the Apocalypse. 
I shall have occasion to refer to this work in the elucidation of the Liturgies which are to follow. If it be, as Bishop Lightfoot supposes, a homily of the second century, it may lend important retrospective aid to the student of these volumes in other particulars; but, having entrusted this interesting relic to the editorial care of a most competent scholar, I shall not presume to anticipate his judgment in any matter.
 If this reference to 2 Peter 3:9 be probable, it is one of the earliest testimonies to the genuine character of that Epistle. The true Clement has two references to the same (pp. 8 and 11, vol. i., this series), and Justin also (vol. i.[p. 240) is credited with a similar reference to 2 Peter nd the Apocalypse. See Lardner, Credib., vol. ii. p. 123 et seq.
