The scientific treatment of the Geography of Ptolemy (Γεωγραφικὴὑφήγησις) had made considerable progress during the last century, so that it seemed as if this work had been brought at least to a provisory issue. An edition arranged according to the demands of science and, as was to be desired, an edition that could be called final had not yet been produced, but there was reason to believe that the edition undertaken by the well-known editor C. Mueller in the great Bibliotheca Scriptorum Graecorum, published by Firmin Didot in Paris, would come up to these expectations. However, owing to his death in 1893 it has remained unfinished. After Part I. had appeared in 1883, C. Th. Fischer, to whom the continuation of the work was entrusted, was able in 1901 to publish Part II., which had been found almost ready for the press among the literary remains of the deceased.
