M426 Stick Barometer
Bow front mahogany stick barometer of excellent quality by the noted London maker Dollond. Full depth swan neck pediment at the top over brass framed bow glass with externally operated venier (right knob). To the left of this knob is another key-hole for operating the hygrometer which is just beneath. Below that is the original bow-glass, brass-framed mercury thermometer, also with a key-hole beneath for operating a movable pointer on the thermometer.
