Thermometer in a mahogany case, made by Adams of Fleet Street, 1811
Mahogany with glass and engraved brass
Height: 10 in
Museum number: BR2
This thermometer was manufactured by Dudley Adams of 60 Fleet Street, London, 'Globe and Mathematical Instrument maker to the King'. The bill, dated 5 January 1811, is the Soane Archive [SM Papers connected with purchases / item 2] and describes it as 'A Thermometer with Fahrenheit's & Reaumur's Scale in a mahogany frame. £1.16.0'. Interestingly the bill seems to be addressed to 'Mrs Soane'. 'Reaumur's scale' is a reference to the French Reaumur scale, also known as the "octogesimal division', a temperature scale in which the freezing and boiling points of water are set to 0 and 80 degrees respectively. It is named after the Frenchman Rene Antoine Ferchault de Reaumur, who first proposed something similar in 1730.
