P A Oxley Antique Clocks & Barometers has dated this Bow Front Stick Barometer to the 19th Century.
The main scale also features a sliding rack and pinion vernier controlled with a bone set key and is protected with its original bowed glass.

The silvered brass thermometer is calibrated from 10º to 120º Fahrenheit and from 10º to 40º Reaumur and is contained within a mahogany box surround, again with its original bowed glass.
The high quality and substantially made mahogany veneered cabinet work has flame mahogany veneers to the bowed front, ebony mouldings and line edge inlay throughout and a typical ogee moulding above. To the base we find an ebony cistern cover, ebony mouldings, further ebony inlay to the sides and a transportation screw built within the case.

An exceptional Instrument.
Note: The Dollond family were prolific and excellent instrument makers. We can determine from its style that this barometer is by George Dollond. Like his famous Uncle Peter Dollond, he was also instrument maker to William IV and Queen Victoria and was one of sixteen instrument makers who exhibited at the Great Exhibition, Crystal Palace in 1851. Born in 1774, George was in Partnership with Peter Dollond until he died in 1820. George then continued the business until he died himself in 1856.
