12mo. 107 pp, plus engraved frontispiece. Bound in contemporary purple wrappers; edges deckled and partially untrimmed, with some dog-earing; later marbled paper spine. Blank versos of frontispiece and final leaf glued to wrappers. A good survival of a rare livre de poche. Ink ownership inscription (or authorial attribution) in lower corner of title-page [erroneously?] dated 1799.
