HOLDEN, Henry. Divinae fidei analysis. Paris, Barbou, 1767.
Hollowed-out book. 8vo. Contemporary mottled calf, lettered and decorated in gilt; marbled endpapers, after p. 6 hollowed out cavity and lined with marbled paper, marbled edges and endpapers; extremities a little rubbed, otherwise good.
A charming non-book, made to conceal something in an English Catholic's work.
