Whitney's Revisers' Greek Text
S. W. Whitney, The Revisers' Greek Text: A Critical Examination of Certain Readings, Textual and Marginal, in the Original Greek of the New Testament Adopted by the Late Anglo-American Revisers. Boston : Silver, Burdett & Company, 1892.
This work is footnoted by Metzger as one of the few textual commentaries on the NT to appear before his own. Whitney discusses, often in considerable detail, about 700 readings followed in the RV that had been changed from the KJV. He usually concludes in favour of the TR or corrects it to the majority of Greek MSS, but he is his own man.
