Second illustrated edition, with 68 wood engravings within the text.
The first leaf bears, on its verso, a few lines of music (the recto is blank). On the final leaf, the same score reveals, when folded, lines of writing: "Les notes musicales qui servent de Frontispice à cet Ouvrage, ressemblent parfaitement au Discours & à la Musique ci-dessus. C'est la manière de plier le papier qui fait paraître l'un & disparaître l'autre" (cf. Fechner, p. 152).

A pleasant copy.
