Schwartze only lived to complete the four Gospels. He had, however, made some collations for the Acts and Epistles during his last visit to England; and after his death they were placed in the hands of P. Boetticher, who continued the work. The titles of Boetticher’s editions are “Acta Apostolorum Coptice,” and “Epistulae Novi Testamenti Coptice,” both dated Halae, 1852. His plan, however, differs wholly from Schwartze’s. He substitutes an 8vo size for the 4to of his predecessor; and he gives no translation or collation with the Greek, but contents himself with noting the variations of his MSS. in Coptic at the foot of the page. Thus his book is absolutely useless to any one who is unacquainted with the language. Moreover his materials, though less scanty than Schwartze’s, are far from adequate. For the Acts and for the Catholic Epistles he employed Schwartze’s collations of two English MSS., which he calls _tattamianus_ and _curetonianus_, and himself collated or obtained collations of two others in the Paris Library (_p_), (_m_); while for the Pauline Epistles he again used Schwartze’s collations of the same two English MSS., together with _another_ Paris MS. (_p_), and the Berlin MSS., which will be described below. The account, which he gives in his preface, of the MSS. employed by him is so meagre, that in some cases they are with difficulty identified. Nor again are the collations used for this edition nearly complete. I have pointed out below the defects in Schwartze’s collation of one of the English MSS., which I have partially examined; and Brugsch in an article in the “Zeitschr. der Deutschen Morgenl. Gesellsch.,” vii. p. 115 sq. (1853), has given a full collation of the Berlin MS. of the Epistle to the Romans, showing how many variations in this MS. are not recorded in Boetticher’s edition. The Apocalypse has never appeared.
