Philip Salmuth (Observationes Medicæ, Centuria II, no. 63) in the seventeenth century recorded a case in which a young girl of noble birth (whose sister was fond of eating chalk, cinnamon, and cloves) experienced extreme pleasure in smelling old books. It would appear, however, that in this case the fascination lay not so much in the odor of the leather as in the mouldy odor of worm-eaten books; "fætore veterum liborum, a blattis et tineis exesorum, situque prorsus corruptorum" are Salmuth's words.
