Barometer
This barometer was made in Paris around 1852 by Edward J. Dent (1790-1853), a scientific instrument maker based in London. It is a type known as an aneroid barometer (from the Greek, meaning 'not wet') and has a small Fahrenheit thermometer.
The instrument has a partly evacuated copper chamber connected by an iron frame to a spring which leads to a lever system and the rod to which the pointer is attached. The scale is signed 'E. J. DENT / Paris/ 6890'.
This form of aneroid barometer was invented by Lucien Vidie (1805-66), who patented it in his native France in 1845 and in Britain in 1850.
