James Gatty London Circa 1790
A very rare 18th century mahogany stick barometer by this famous maker
The main silvered brass scale is calibrated from 28″ to 31″ and incorporates a sliding silvered brass vernier with a brass knob and pointer. The scale also displays typical weather indications from Stormy to Very Dry. The makers name is engraved to the top of the scale, James Gatty , London, also with very delicately engraved foliage.
Height: 43½ inches (111 cm)
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.
