aware of their existence, or even found them in the copy from which he wrote. The capital letters at the beginning of each book are likewise due to the corrector, who sometimes erased, sometimes merely touched slightly, the original initial letter, which (as in the Herculanean rolls) is no larger than any other. The _paragraph_ marks (usually straight lines, but sometimes [symbol](140)) are seen quite frequently in some parts; whether from the first hand is very doubtful. The note of citation > is perpetual, not occasional as in Cod. א. Fewer abridgements than usual occur in this venerable copy. The formation of _delta_, _pi_, _chi_; the loop-like curve on the left side of _alpha_; the absence of points at the extremities of _sigma_ or _epsilon_; the length and size of _rho_, _upsilon_, _phi_, all point to the FOURTH century as the date of this manuscript. The smaller letters so often found at the end of lines preserve the same firm and simple character as the rest; of the use of the apostrophus, so frequent in Codd. א, A and some others, Tischendorf enumerates ten instances in the New Testament (N. T. Vatican. Proleg. p. xxi), whereof four are represented in the Roman edition of 1868, with two more which Tischendorf considers as simple points (Acts vii. 13, 14). Tischendorf says truly enough that something like a history might be written of the futile attempts to collate Cod. B, and a very unprofitable history it would be. The manuscript is first distinctly heard of (for it does not appear to have been used for the Complutensian Polyglott(141)) through Sepulveda, to whose correspondence with Erasmus attention has been seasonably recalled by Tregelles. Writing in 1533, he says, “Est enim Graecum exemplar antiquissimum in Bibliothecâ Vaticanâ, in quo diligentissimè et accuratissimè literis majusculis conscriptum utrumque Testamentum continetur longè diversum a vulgatis exemplaribus”: and, after noticing as a weighty proof of excellence its agreement with the Latin version (multum convenit cum vetere nostrâ translatione) against the common Greek text (vulgatam Graecorum editionem), he furnishes Erasmus with 365 readings as a convincing argument in support of his statements. It would probably be from this list that in his Annotations to the Acts, published in 1535, Erasmus cites the reading καῦδα, ch. xxvii. 16 (“quidam admonent” is the expression he uses), from a Greek codex in the Pontifical Library, since for this reading Cod. B is the only known _Greek_ witness, except a corrector of Cod. א. It seems, however, that he had obtained some account of this manuscript from the Papal Librarian Paul Bombasius as early as 1521 (_see_ Wetstein’s Proleg. N. T., vol. i. p. 23). Lucas Brugensis, who published his Notationes in S. Biblia in 1580, and his Commentary on the Four Gospels (dedicated to Cardinal Bellarmine) in 1606, made known some twenty extracts from Cod.
