τῆς τοῦ βιβλίου διεξαγωγῆς λεγομένης. Valesius considers διεξαγωγή equivalent to dispositionem or οἰκονομίαν, “for διεξαγωγεῖν is the same as διοικεῖν, as Suidas says.” He translates ex libelli totius ductu ac dispositione, remarking that the words may be interpreted also as formam et rationem scribendi, seu characterem. The phrase evidently means the “general disposition” or “form” of the work. Closs translates “aus ihrer ganzen Ausführung”; Salmond, “the whole disposition and execution of the book”; Crusè, “the execution of the whole book.”
