Consolidated into a single Nicolas Demeuse work record so that the 1778 first edition and the 1786 second edition are carried as editions rather than as separate works. Thimm's entry for the plate suite and Gelli's fuller 1778 title are treated as witnesses to the same work family.
Gelli cites an undated new-edition witness in the Demeuse family.
Castle records the Demeuse family at Liège in 1778 and 1786, and a later Lille/Paris 1800 state with an appended dictionary of the art of arms.
Vigeant 1882 confirms the 1778 Liege first edition, the Graillet arms, the 14 plates, and the treatise's status as a modern demonstrator's work that earned three editions.
Vigeant 1882 adds the 1786 second edition without the arms of M. de Graillet and a third edition around 1800 at Lille, printed by Blocquel, with a fencing dictionary and a different plate suite.
