I adjure thee, who shalt transcribe this book,  by our Lord Jesus Christ, and by His glorious appearing, when He comes to judge the living and the dead, that thou compare what thou hast transcribed, and be careful to set it right according to this copy from which thou hast transcribed; also, that thou in like manner copy down this adjuration, and insert it in the transcript.
 This fragment is quoted by Eusebius, Hist. Eccl., v. 20. It occurred at the close of the lost treatise of Irenæus entitled De Ogdoade.
