quarto volumes was issued. The titles of these new sections give a sufficient idea of their contents. The _Scriptores_ are divided into _Auctores antiquissimi_, _Scriptores rerum Merovingicarum_, _Scriptores rerum Langobardicarum et Italicarum_, _Libelli de lite imperatorum et pontificum_, _Gesta pontificum Romanorum_ and _Deutsche Chroniken_, or _Scriptores qui vernacula lingua usi sunt_. The _Leges_ are divided into _Leges nationum Germanicarum_, _Capitularia regum Francorum_, _Concilia_, _Constitutiones imperatorum et regum_ and _Formulae_. Three quarto volumes of _Diplomata regum et imperatorum Germaniae_ and one of _Diplomata Karolingorum_ had been published by 1909. Work was also begun upon the _Antiquitates_ and the _Epistolae_. The sections of the former are _Poëtae Latini medii aevi_, _Libri confraternitatum_ and _Necrologia Germaniae_, and of the latter _Epistolae saeculi XIII._ and _Epistolae Merovingici et Karolini aevi_. Meanwhile the publication of the _Scriptores_ proper continues, although the thirty-first and subsequent volumes are in quarto and not in folio, and the number of volumes in the whole undertaking is continually being increased. The archives of the _Gesellschaft_ have been published in twelve volumes, and a large number of volumes of the _Neues Archiv_ have appeared. Some of the MSS. have been printed in facsimile, and an index to the _Monumenta_, edited by O. Holder-Egger and K. Zeumer, appeared in 1890. The writings of the more important chroniclers have been published separately, and many of them have been translated into German. It will thus be seen that the ground covered by the _Monumenta_ is enormous. The volumes of the _Scriptores_ contain not only the domestic chroniclers, but also selections from the work of foreign writers who give information about the history of Germany--for example, the Englishman Matthew Paris. In the main these writings are arranged in chronological order. Each has been edited by an expert, and the various introductions give evidence of the number of MSS. collated and the great pains taken to ensure textual accuracy on the part of the different editors, among whom may be mentioned Mommsen and Lappenberg. Other great names in German historical scholarship have also assisted in this work. In addition to Waitz the _Leges_ section has enjoyed the services of F. Bluhme and of H. Brunner, and the _Diplomata_ section of T. Sickel, H. Bresslau and E. Mühlbacher.
