A fine George III mahogany cistern tube stick barometer with hygrometer or Triple Weather Glass, by Benjamin Martin, London, circa 1760, the arched top case with leaf carved surround for the inset herringbone border engraved vernier scale with arched hygrometer scale above Fahrenheit and Reaumur mercury thermometer and signed B. Martin, London , the caddy moulded trunk with scroll carved edges to throat and exposed tube above hemispherical cistern cover mounted onto the scroll edged rounded base, 93cm high, 10.5cm wide, 4cm, deep Provenance: The Edwin Banfield Collection of Barometers, Dreweatts, Donnington Priory, Newbury, 4th September 2007, lot 62. Literature: Illustrated in Banfield, Edwin ºROMETERS, Stick or Cistern Tube' (Baros Books, Trowbridge, 1985) pages 58-59. Benjamin Martin worked 1756-82 and was a prolific writer on the subjects of science, art and instruments who launched a monthly magazine entitled 'General magazine of the Arts and Sciences' in 1755. He is thought to have been the first maker to incorporate a hygrometer into a barometer with thermometer and marketed the instrument as a 'Triple Weather Glass'. The hygrometer utilises a length of gut (which expands and contracts with variations in humidity) linked to a rack and pulley rather than the simple oat beard found on later instruments.
