Wind gauge, known as Snow-Harris anemometer

This wind gauge, known as a Snow-Harris anemometer, was made around 1860, probably by John Lilley & Son, scientific instrument makers based in London.

The device has a tube which is half filled with water to a central zero mark. The air forced into one end of the tube pushes the water up, allowing the wind speed to be measured on the scale.

The instrument is named after its designer William Snow-Harris (1791-1867). Harris based his work, published in 1858, on the first satisfactory syphon wind gauges by James Lind in 1775, which made use of U-shaped glass tubes.
