(Animal magnetism). LAFONTAINE (Ch.). L'ART DE MAGNETISER ou le magnétisme animal considéré sous le point de vue théorique, pratique et thérapeutique. Paris, Germer Baillière, 1847. In-8, blue half-chagrin, smooth spine decorated throughout, marbled edges (modern binding). Rare first edition. This is one of the best treatises that can be recommended to anyone wishing to practise magnetism. A famous magnetist, the author fights against the marvellous and the supernatural and seeks to propagate magnetism by experimental means. Long handwritten note glued to the back cover, the binder has glued the original spine to the binding, otherwise a good copy (Caillet II, 5966).
