D'AUBERNY, L'Irrésistible puissance, [v.1910]

First edition.
A curious work in which Professor d'Auberny praises the powers of his magic ring "La Rénovatrice": "The composition of the metal is such that its effect must be infallible. It has a surprising radioactivity and, through the condensation of the powerful elements it contains, an incalculable power".
The work is illustrated on almost every page by Verdier with compositions depicting the powers of the ring.
