The nucleus of the collection displayed in Room XIX consists of the elegantly and elaborately decorated eighteenth- and nineteenth-century pharmaceutical jars from the Santa Maria Nuova hospital in Florence. There is also a variety of basic equipment for pharmacological research and practice such as small bottles, retorts, mortars, assorted containers, and portable pharmacies. Their dates range from the Renaissance to the eighteenth century. Portable pharmacies, for first aid, typically consisted of boxes carrying pharmaceutical preparations and a few essential surgical instruments. Also exhibited is a precision balance formerly belonging to the Chemistry Laboratory of the Museo di Fisica e Storia Naturale. A copy of a panel from Giotto's Campanile [bell tower] represents a dispensary where women have brought urine glasses with samples to be analyzed. The entire pharmaceutical collection suffered heavy damage from the Arno flood in 1966, but nearly all the items were salvaged thanks to outstanding restoration work.
