Des hallucinations, ou, Histoire raisonnée des apparitions, des visions, des songes, de l'extase, du magnétisme et du somnambulisme / par A. Brierre de Boismont.
A French study of hallucinations, visions, dreams, ecstasy, mesmerism and sleepwalking, written by the physician Alexandre Brierre de Boismont and published in Paris in 1852 by Germer Baillière. The two plates are bookplate-style engravings for the Royal College of Physicians of London, showing a central shield and crest framed by ornate scrolling foliage, with an open book and a crossed pair of staffs or keys at the base. A designer might take from them the symmetrical framing, the strapwork and acanthus scrolls, and the classical lettering used in heraldic emblems.
