In a letter dated November 7, 1580, Martin Chemnitz speaks of two Dresden folio editions of the German Book of Concord, while Feuerlinus, in 1752, counts seven Dresden editions. As a matter of fact, the Dresden folio copies differ from one another, both as to typography and contents. Following are the chief differences of the latter kind: 1. Only some copies have the liturgical Forms of Baptism and of Marriage appended to the Small Catechism. 2. The Catalogus is not entitled "Appendix" in all copies, because it was not regarded as a part of the confession proper. 3. In some copies the passage from the Augsburg Confession, quoted in Art. 2, 29 of the Solida Declaratio, is taken, not from the Mainz Manuscript, but from the quarto edition of 1531, which already contained some alterations. 4. Some copies are dated 1580, while others bear the date 1579 or 1581. Dr. Kolde gives it as his opinion that in spite of all these and other (chiefly typographical) differences they are nevertheless all copies of one and the same edition, with changes only in individual sheets. (_Historische Einleitung in die Symbolischen Buecher der ev.-luth. Kirche,_ p. 70.) Dr. Tschackert inclines to the same view, saying: "Such copies of this edition as have been preserved exhibit, in places, typographical differences. This, according to Polycarp Leyser's _Kurzer und gegruendeter Bericht,_ Dresden, 1597 (Kolde, 70), is due to the fact that the manuscript was rushed through the press and sent in separate sheets to the interested estates, and that, while the forms were in press, changes were made on the basis of the criticisms sent in from time to time, yet not equally, so that some copies differ in certain sheets and insertions."
