A fine and rare Victorian carved walnut marine stick barometer with double scale and sympiesometer J. Campbell, Liverpool, circa 1870. With foliate carved crest and cavetto cornice above bevel glazed angled ivory scales labelled 10A.M. to Day and 10A.M. Yesterday and signed John CAMPBELL, 7 SOUTH CASTLE STRT, LIVERPOOL above dual ivory vernier adjustment discs to throat, gimbal mounting flanges and rectangular bevel glazed IMPROVED SYMPIESOMETER with silvered temperature and adjustable pressure scales, setting disc and Fahrenheit mercury thermometer to shaft above ogee profile acanthus carved terminal to base issuing moulded brass cistern, lacking gimbals, 100cm high, B.C. Ref. 88. Illustrated in Banfield, Edwin BAROMETERS Stick or Cistern Tube page 177. John Campbell is recorded by Banfield as working from 6 & 7 South Castle Street, Liverpool circa 1860-80. This barometer incorporates a sympiesometer which was invented by Alexander Adie of Edinburgh in 1818 as an alternative to the standard marine barometer. The sympiesometer works by measuring the relative atmospheric compression of hydrogen in the upper section of a syphon tube filled with almond oil. However, as hydrogen will expand and contract with variations in temperature, the pressure scale first needs to be calibrated against a temperature reading (from the thermometer placed next to the syphon tube) before the atmospheric pressure can be ascertained. The main benefit gained from using a sympiesometer rather than a mercury barometer whilst at sea is that it is less susceptible to the motion of the ship and easily calibrated for variations in temperature.

A black japanned Kew pattern marine barometer with Gold slide thermometer Negretti & Zambra, London, circa 1940. With brass cap above glazed cylindrical silvered vernier scale calibrated in millibars signed NEGRETTI & ZAMBRA, LONDON and inscribed BAROMETER, MARINE MK.2. REF. MET. 1542, the cylindrical shaft with brass vernier adjustment knob, gimbal wall mountings, STANDARD CONDITIONS plate and mercury thermometer with Gold type adjustable scale above cylindrical steel cistern cover, 91cm high, in original pine carrying case, 100cm high overall, B.C. Ref. 93. Illustrated in Banfield, Edwin BAROMETERS Stick or Cistern Tube page 179 and described on page 178. The firm of Negretti & Zambra is recorded by Banfield as being established when a partnership between Enrico Negretti and Joseph Warren Zambra was formed in 1850. The firm expanded rapidly throughout the 19th century to become one of the largest manufacturers of scientific instruments and continued trading throughout the 20th century. In 1914 E. Gold of the Meteorological Office suggested adopting the millibar as the unit to be used for measuring atmospheric pressure and it was consequently adopted for daily weather reports from 1st April 1914 and was used on Station and Marine barometers from this date onwards. On the current example the thermometer incorporates a series of slides to the scale which were also devised in 1914 by E. Gold and allow corrections to be made for latitude, height of cistern above mean sea level, mean Index error as well as temperature for any given barometer reading. The barometer also incorporates a capillary bore contraction and Bunten air trap to the tube to assist in its use at sea. The silvered scale is numbered MO.M4694/44/54/58 which indicates that the instrument was returned to the makers for checking in 1944, 54 & 58, the Gold thermometer scale has a similar series of check date numbers. This barometer is an example of the final fully developed mercury marine barometer and retains its original pine packing case.
