A closely related example is illustrated and described in Claxton Stevens, Christopher and Wittington, Stewart 18th CENTURY ENGLISH FURNITURE, THE NORMAN ADAMS COLLECTION, page 463. The Royal Society scale thermometer was devised by Robert Hooke in 1664 and was calibrated to every degree representing an increase of 1/500 in volume of the thermometer liquid. The scale used the freezing point of water as the fixed point and was scaled from high to low with the increase of temperature. As the rate of expansion of the alcohol varied between instruments, each scale had to be individually made for the instrument. The current Lot has a replacement silvered scale as the original paper scale had probably become to worn and discoloured to read. Hooke’s original thermometer was adopted and became known as the standard of Gresham College and used by the Royal Society until 1709. £2,500-3,500 21 A William and Mary style olivewood cistern tube stick barometer in the manner of John Patrick Unsigned, circa 1695 and later The superstructure with arched pediment, brass ball finials and swollen frieze above fretwork upright flanked by ebonised twist turned columns, the later silvered herringbone border and foliate engraved two-part break-arch scale with brass setting pointer above replaced exposed bulb-cistern tube flanked by cross-grain veneers and ebonised caddy moulded edge above fretwork flared side panels and later half-round ring-turned cistern cover with ogee moulded underside, (restorations and replacements) 120cm high. The decorative ‘hood’ superstructure which incorporates spiral twist columns emulates the design of longcase clock from the end of the 17th century and bears similarities to examples depicted in John Patrick’s advertisement of circa 1710 reproduced in Goodison, Nicholas English BAROMETERS 1680-1860 page 48. Although this configuration appeared to be popular well into the first two decades of the 18th century, Edwin Banfield suggests (BAROMETERS Stick or Cistern Tube page 18) that the use of fretwork in the case indicates a date prior to 1700. £1,500-2,500 www.dnfa.com/donnington
