It would have been a grievous reproach had no efforts been made to supply so great and acknowledged a want. Early in 1866, Tischendorf again visited Rome, and when admitted into the presence of Pope Pius IX, boldly sought permission to edit at his own cost such an edition of Cod. B as he had already published of Cod. א. The request was denied by his Holiness, who obscurely hinted his intention of carrying out the same design on his own account. Tischendorf, however, obtained permission to use the manuscript so far as to consult it in such parts of the New Testament as presented any special difficulty, or respecting which previous collators were at variance. He commenced his task February 28, and in the course of it could not refrain from copying at length twenty pages of the great Codex—nineteen from the New Testament, and one from the Old. This licence was not unnaturally regarded as a breach of his contract, so that, after he had used the manuscript for eight days, it was abruptly withdrawn from him on March 12. An appeal to the generosity of Vercellone, who had been entrusted with the care of the forthcoming edition, procured for him the sight of this coveted treasure for six days longer between March 20 and 26, the Italian being always present on these latter occasions, and receiving instruction for the preparation of his own work by watching the processes of a master hand. Thus fourteen days of three hours each, used zealously and skilfully, enabled Tischendorf to put forth an edition of Cod. B far superior to any that preceded it(150). The Prolegomena are full of matter from which we have drawn freely in the foregoing description, the text is in cursive type, the nineteen pages which cost him so dearly being arranged in their proper lines, the remainder according to columns. Much that ought to have been noted was doubtless passed over by Tischendorf for mere pressure of time; but he takes great pains to distinguish the readings of the original writer or his διορθωτής (_see_ p. 55)(151), both of whom supplied words or letters here and there in the margin or between the lines(152), from the corrections of a second yet ancient scribe (B2), and those of the person (B3) who retraced the faded writing at a later period(153). One notion, taken up by Tischendorf in the course of his collation in 1866, was received at first with general incredulity by other scholars. He has pronounced a decided opinion, not only that Codd. א and B are documents of the same age, but that the scribe who wrote the latter is one of the four [D] to whose diligence we owe the former. That there should be a general similarity in the style of the two great codices is probable enough, although the letters in Cod. א are about half as large again as those of its fellow, but such as are aware of the difficulty of arriving at a safe conclusion as to identity of penmanship after close and repeated comparison of one document with another, will
