Five studies on the textual criticism of the New Testament are presented here: notes on the text of Revelations, the corrections to the Codex Sinaiticus in the hand which attributes its work to the manuscript of the martyr Pamphilus, some notes on the recension of the Septuagint by Hesychius of Alexandria, a sample of the readings in the Gospels of the Codex Petropolitanus and its Byzantine relatives, and notes on the text of Acts.
