The thermometer scale is mounted onto the main column of the barometer and features a long silvered brass scale reading from -20 to 160 degrees Fahrenheit, engraved with the legend “just freeze” to “Fever heat” The mercury thermometer is attached to the scale with brass loops.
An additional and rare feature is an adjustable hygrometer which can be centred with an ivory knob beneath it.
The superbly made and well proportioned cabinet work incorporates box wood feather banding and two glazed doors, one covering the main scale and the other the thermometer scale, together with a well made mahogany cistern cover. There is also a transportation screw below. The typical architectural top is finished with a central brass finial.
Note: James Gatty was one of the earliest Italian barometer makers who appears to have started working in London during the 1780’s. He was a well respected instrument maker and specialised in high quality and unusual wheel and stick barometers. This is a rare and unusual example.
