Some volumes of ghost stories
The work Mary Shelley cites is
Fantasmagoriana; ou Recueil d'Histoires
d'Apparitions, de Spectres, Revenans, Fantômes, &c. Traduit de
l'allemand, par un Amateur, 2 vols. (Paris, 1812), anonymously
published by Jean Baptiste Benoît Eyriès (1767-1846). The
following year, in turn, this text was translated into English as Tales
of the Dead. Principally Translated from the French (London: White,
Cochrane, and Co., 1813). This English
translation is included, as being more universally accessible to a
reader of Frankenstein.
