As the original Greek is unknown, and as no English translation of the Syriac has yet been published, I was induced to undertake one two years ago at the suggestion of the Rev. Canon F. E. Warren. My reason for editing the Syriac text as well is that the Paris Codex (Codex Sangerma- nensis) above mentioned no longer stands alone. Dr J. Rendel Harris, whilst in Mesopotamia a few years ago, succeeded in obtaining an accurate copy of an ancient Syriac MS., which he most kindly placed at my disposal, and from it my text is printed. It contains a long addition to Chapter III. which is not contained in Cod. Sang. ; there is also a different arrangement of the text in Chapter VI.
