The first of these two similar thermometers is divided into one hundred, one of the many thermometric scales adopted by the Accademia del Cimento. It has a spherical bulb and white enamel inscriptions ("Arno A3G Alla Tinozza A"). The second, divided into eighty degrees, carries the inscription "Alla Tinozza A Gradi 77 1/2 Arno A Gradi 47 1/2"). These markings refer to readings in the Arno river for the minimum temperature and in a tinozza [tub filled with hot water] for the maximum. The thermometric liquid is acquarzente.
