Résumé : We establish the "stammbaum" organization of textual variations in editions whose printers are identified by their typographical material: Jay and Veuve Duchesne in Paris, Castaud in Lyon, Chambon in Paris, Fantet in Besançon. We propose that some variations are due to the author, S. Mercier, himself and that Jay's edition of 1772, as well as an un-dated Brunet edition, announces the definitive 1786 edition.
