Apart from the above title this copy differs from the others we examined in various ways Everywhere (at four different places) it bears the date 1579, which, on the chief title-page, however, seems to have been entered in ink at a later date. Also the place of publication, evidently Dresden, is not indicated. Two variations are found in the Preface to the Book of Concord, one an omission, the other an addition. The signatures of the princes and estates to the Preface are omitted. Material and formal differences are found also on the pages containing the subscriptions of the theologians to the Formula of Concord; and the Catalogus is lacking entirely. The typography everywhere, especially in the portions printed in Roman type, exhibits many variations and divergences from our other four copies, which, in turn, are also characterized by numerous typographical and other variations. The copy of which, above, we have given the contents is dated throughout 1580. Our third copy bears the same date 1580, excepting on the title-page of the Solida Declaratio, which has 1579. In both of these copies the typography of the signatures to the Book of Concord is practically alike. In our fourth copy the date 1580 is found on the title-page of the Concordia, the Catalogus, and the appended Saxon Church Order, which covers 433 pages, while the title-pages of the Epitome and the Declaratio and the page carrying the printer's imprint are all dated 1579. In this copy the typography of the signatures closely resembles that of the copy dated everywhere 1579. In our fifth Dresden folio copy, the title-page of the Book of Concord and the Catalogus are dated 1580, while the title-pages of the Epitome and Solida Declaratio are dated 1579. This is also the only copy in which the Catalogus is printed under the special heading "Appendix." In view of these facts, especially the variation of the Roman type in all copies, Kolde's hypothesis will hardly be regarded as firmly established. Even if we eliminate the copy which is everywhere dated 1579, the variations in our four remaining Dresden folio copies cannot be explained satisfactorily without assuming either several editions or at least several different compositions for the same edition, or perhaps for the two editions mentioned by Chemnitz. Feuerlinus distinguishes seven Dresden editions of the Book of Concord--one, printed for the greater part in 1578, the second, third, and fourth in 1580, the fifth in 1581, the sixth also in 1581, but in quarto, and the seventh in 1598, in folio. (_Bibliotheca Symbolica,_ 1752, p. 9.) A copy like the one referred to above, which is everywhere dated 1579, does not seem to have come to the notice of Feuerlinus.
