Giovanni Kalabergo arrived in Banbury from Italy in around 1810 and later anglicised his name to John. He was, in 1851, also joined by his nephew who shared his name but took to calling himself William. Unfortunately William did not take kindly to his uncle's demanding demeaner and he sought to address the problem by hatching a plan to murder him and inherit his property. In January 1852 William bought himself a gun and joined his uncle on a normal work-related trip out of town. Whilst descending d Williamscot Hill William drew the gun and shot his uncle. On returning to Banbury he reported to the Police that they had been set-upon by bandits and that his uncle resisted (allowing William to escape) but had been shot.On investigation the Police suspected foul play as nothing had been stolen from Giovanni and William was in possession of the murder weapon together with ammunition and a blood-stained rag. William was subsequently trialled and found guilty of his uncle's murder. Whilst in prison awaiting execution he made two attempts to escape; the infamy of his trial was reported throughout the country and resulted in around 10,000 people attending his hanging, a folk ballad also records his fate:In Italy I was bred and born,At Oxford town I must die with scorn;For murdering my uncle as you may see,Has brought me to the gallows tree.Condition Report: Tube has been removed but pulley mechanism is present; will require tube, lines and weights/floats. The dial has overall light to moderate oxidation to the silvering otherwise is in good original condition. The thermometer is intact but the glass to the housing is cracked/damaged. The silvering to the thermometer scale has some patchy oxidation. The case is in sound original condition with notable faults limited to bruising to the surface around the lower inlaid rosette, some light lifting to the side veneers and further light bruising/scuffs to the mouldings of the pediment. Faults are otherwise limited to minor bumps and scuff and the rear door is missing two securing screws for the upper hinge. Surface/finish is generally a little flat. Condition Report Disclaimer

Alexander Adie was particularly noted for his meteorological instruments and is perhaps best known as the inventor of the Sympiesometer in 1818. In recognition of his work he was elected a Fellow of the Royal Society of Edinburgh in 1819. He was appointed optician to William IV and later Queen Victoria and took one of his sons, John, into partnership in 1835. Two of his other sons set up businesses; Richard in Liverpool from 1837 and Patrick in London from 1846. Unfortunately John Adie was prone to fits of despondency' which resulted in him shooting himself in 1857, Alexander Adie died the following year - no doubt expediated by the stress of his son's demise. Richard Adie subsequently spent a lot of time in Edinburgh looking after the business of Adie and Son up until his death in 1881.The Kew pattern marine barometer was developed prior to 1855 by John Welsh of the Kew Observatory and Patrick Adie and included refinements such as iron cistern beneath thermometer bulb within the brass tube case (in order for the temperature reading to mirror that of the mercury in the tube), a restriction in the bore of the tube (to dampen the movement of the mercury) and a Bunten air trap.

The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is a textbook example of a Fishery or Sea Coast storm barometer devised by Admiral Robert Fitzroy in the 1860`s to aid mariners in the forecasting of storms. Fitzroy lobbied the Board of Trade resulting in this type of barometer being supplied (at public expense) to many coastal communities for display in a prominent public space. In addition to this The Royal Lifeboat Institution installed these barometers into each of its stations and the Duke of Northumberland (in association with the British Meteorological Society) erected several on the coast of Northumberland. By 1864 over 80 barometers had been installed by the Board of Trade and a further 14 by the Duke of Northumberland with their usefulness fully appreciated in Fitzroy's Meteorological Office Report published that year.Condition Report: Instrument is generally in fine original condition with the tube filled with mercury with no air present. The barometer scales are undamaged. The thermometer scale is also in good original condition although the ceramic scale has a few light spots of browning mainly towards the edges. The case is in fine original unrestored condition with faults very much limited to a few minor bumps, scuffs, age related grime and tarnishing to the lacquered brass fittings hence can be described as having genuine light age-related patina. Condition Report Disclaimer

Comitti and Son, LONDON to the right hand side opposing Fahrenheit and Centigrade scale alcohol thermometer to the left, set behind chevron-edged hinged glazed door over trunk with visible tube flanked by conforming vertical parquetry inlay and ring-turned domed cistern cover to the rounded base.96.5cm (38ins) high excluding brass finial, 14cm (5.5ins) wide. Provenance: The retail stock of Barometer World Museum, Merton Devon.

AN UNUSUAL GEORGE III STYLE CHEVRON-STRUNG MAHOGANY ANEROID FLUID TUBE STICK BAROMETERUNSIGNED, LATE 20th CENTURYWith swan neck pediment over silvered Vernier scale calibrated in barometric inches and with the usual observations to the right hand side opposing Fahrenheit and Centigrade scale alcohol thermometer to the left, set behind chevron-edged hinged glazed door over trunk with visible tube filled with light-green translucent fluid flanked by conforming vertical parquetry inlay and ring-turned domed cistern cover to the rounded base enclosing transverse mounted four-segment aneroid chamber and pivoted linkage connecting to a diaphragm chamber fitted at the base of the tube. 96.5cm (38ins) high excluding brass finial, 14cm (5.5ins) wide. Provenance: The retail stock of Barometer World Museum, Merton Devon. The above lot utilises and aneroid mechanism connected to a diaphragm to raise and lower the level of a column of green dyed fluid in the tube. This system was developed by Philip Collins of Barometer world in order to create an instrument that has the attractive visual qualities of a stick barometer but with the practicalities of an aneroid barometer. 

AN UNUSUAL GEORGE III STYLE CHEVRON-STRUNG MAHOGANY ANEROID FLUID TUBE DWARF STICK BAROMETERUNSIGNED, LATE 20th CENTURYWith swan neck pediment over silvered Vernier scale calibrated in barometric inches and with the usual observations to the right hand side opposing Fahrenheit and Centigrade scale alcohol thermometer to the left, set behind chevron-edged hinged glazed door over trunk with visible tube filled with light-green translucent fluid flanked by conforming vertical parquetry inlay and ring-turned domed cistern cover to the rounded base enclosing transverse mounted four-segment aneroid chamber and pivoted linkage connecting to a diaphragm chamber fitted at the base of the tube. 66cm (26ins) high excluding brass finial, 14cm (5.5ins) wide. Provenance: The retail stock of Barometer World Museum, Merton Devon. The above lot utilises and aneroid mechanism connected to a diaphragm to raise and lower the level of a column of green dyed fluid in the tube. This system was developed by Philip Collins of Barometer world in order to create an instrument that has the attractive visual qualities of a stick barometer but with the practicalities of an aneroid barometer. The squat proportions of the present instrument is possible as it does not rely on the weight of a mercury column to provide an indication of barometric pressure. 

A MAHOGANY CASED ADIE-TYPE SYMPIESOMETERPHILIP COLLINS, MERTON, LATE 20th CENTURYThe glazed rectangular case with ogee-moulded pediment above rectangular silvered scale inscribed Adie's Sympiesometer over applied central siphon tube filled with red-stained almond oil incorporating low cistern bulb to the left limb beside tube terminating with a further sealed bulb at the top, the left hand margin with mercury tube Fahrenheit scale thermometer, opposing vertical scale for degrees Fahrenheit ranging between 0 and 160 set behind slide with scale annotated for barometric inches and with the usual weather observations to the right, the upper edge of the slide fitted with angled brass pointer for calibration against the temperature scale behind and with sliding adjustment via a brass knob to the exterior of the case, the lower edge with recessed circular level recording disc labelled Yesterday, engraved with barometric scale visible through an arched aperture in the plate and manually adjusted via projecting rim to the left hand side of the case, the lower margin inscribed Made by, P. Collins, Merton over conforming inverted ogee moulded base.65cm (25.5ins) high, 8cm (3.25ins) wide. Provenance: The retail stock of Barometer World Museum, Merton, Devon. The sympiesometer was invented by Alexander Adie of Edinburgh in 1818 and is essentially an improved version of Robert Hooke's thermobarometer which was subject of a paper presented to the Royal Society in 1668. The instrument works by having a syphon tube filled with liquid open to the air at one end and with trapped gas at the other (sulphuric acid and hydrogen were used in later sympiesometers). As barometric pressure increases the liquid will be forced down the tube causing the gas to be compressed, resulting in a change in level in the tube; however the volume of the gas changes with temperature so before a reliable reading can be taken the instrument would first need to be calibrated by adjusting the position of the movable barometer scale in relation to the temperature scale behind to reflect the reading provided by the thermometer. The sympiesometer was conceived by Adie as an alternative to the mercury marine barometer as it was smaller and believed to be less susceptible to the motion of a vessel at sea.

A RARE AMERICAN WALNUT CASED MERCURY 'UNION' BAROMETER CURRIER AND SIMPSON, THIRD QUARTER OF THE 19th CENTURYThe ogee moulded rectangular glazed case enclosing syphon tube with large mercury bulb reading against a scale calibrated in barometric inches with Vernier with up-down adjustment in tandem with the entire Fahrenheit scale mercury thermometer positioned to the left hand side via a knob to the base of the case, the upper margin stamped CURRIER & SIMPSON, PAT'D JAN 31. 1880 the top of the case with valve for closing the top of the mercury tube to the atmosphere, the rear with pasted paper label providing instructions for use.39cm (15.5ins) high, 13cm (5ins) wide. Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. Surprisingly little appears to be recorded regarding Simpson and Currier, however the current lot was apparently devised as a small portable form of mercury barometer no doubt targeted to frontiersmen amongst others. The instrument utilises a sealed bulb cistern part filled with air connected to a short column. Change in barometric pressure will naturally cause the mercury column to move but also will a change in temperature. In order to allow for the effect of temperature the level of mercury in the thermometer tube has to be first aligned with that of the barometer tube; the Vernier (which is directly connected to the movement of thermometer) will then provide the reading in barometric inches.

They were best known for supplying microscopes and other optical instruments which were presumably constructed in their factory at Lister Works, Kentish Town, Holloway, East London. Banfield further notes that they often signed their instruments 'R & J Beck Ltd' from 1894. 

AN UNUSUAL VICTORIAN CARVED BOXWOOD MINIATURE ANEROID WHEEL BAROMETERTHOMAS ARMSTRONG AND BROTHER, MANCHESTER AND LIVERPOOL, CIRCA 1880The 1.5 inch circular silvered register calibrated in barometric inches divided into hundredths and with the usual observations over signature THOMAS ARMSTRONG & BROTHER, MANCHESTER & LIVERPOOL and serial number 372 set behind glazed rotating milled gilt bezel incorporating recording pointer to the inside edge, the case with fine rosette-centred leafy scroll-carved pediment over applied Fahrenheit silvered scale glazed mercury thermometer to the slender scroll-edge upright, the base with conforming rosette-centred leafy scroll carved decoration.22.5cm (8.875ins) high, 6.5cm (2.5ins) wide. Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. Thomas Armstrong and Brother are recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as working from circa 1875 until after 1900.The unusual size and fine accurate detailing of the current lot would suggest that it was probably intended as a tradesman's sample designed to give trade customers a feel for the overall quality and appearance of the maker's products. 

A VICTORIAN BRASS VIDIE-PATTERN ANEROID BAROMETERE.J. DENT, PARIS, CIRCA 1850The 4 inch circular silvered register calibrated in barometric inches with the usual annotations over curved mercury tube FAHRENHEIT'S THERMOMETER, signature E.J. DENT, Paris and serial number 8501, the cylindrical lacquered brass case with recording pointer to the bevelled glass within moulded surround beneath pivoted suspension ring.12cm (4.75ins) diameter, 4.5cm (1.75ins) deep.Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. Edward John Dent, who at the age of 17, transferred his apprenticeship from the trade of tallow chandler to watchmaking under the charge of Edward Gaudin in 1807. By 1817 he had become well known as a watch and clockmaker receiving commissions from the Admiralty for a 'Standard Astronomical Clock' and pocket chronometers for the Colonial Office Africa Expedition. In 1830 Dent went into partnership with the renowned watch and chronometer maker John Roger Arnold which continued until 1840 when he left and set up business alone as E.J. Dent at 82 Strand, London, primarily making marine chronometers, watches and precision clocks. In 1843 the firm expanded taking on a second premises at 33 Cocksur Street, with the Strand premises moving down the road to number 61 by 1851. In 1852 Edward Dent successfully tendered to make the 'great clock' to be housed in Stephen's tower at the New Palace of Westminster. The clock was completed by 1859, apparently at a financial loss to the firm, however it ensured that Dent became a household name synonymous with fine clockmaking. Unfortunately Edward John Dent did not live to see the installation of the 'great clock' as he died in 1853. He was succeeded by his stepson Frederick Rippon Dent, who, in partnership with his brother Richard, continued to expand the business. By 1862 the firm had added 34 Cockspur Street and 34 & 35 Royal Exchange to their list of addresses and, although having seen natural passage of ownership over the intervening years, the business still continues to trade today as Dent & Co.This type of aneroid barometer was first invented by Lucien Vidie in 1844 and is considered to be the first of its type; Edward John Dent was granted a license by Vidie produce and market instruments to his design which lasted until Dent's death in 1853.

A RARE VICTORIAN EBONISED MITCHEL PATENT BAROMETER OR 'DIFFERENTIAL BAROMETER'R.H.C. WILSON, LONDON, CIRCA 1875The oil filled tube with sealed cistern formed as a radially corrugated capsule set behind a panel inscribed with monogram HB over inscription DIFFETRENTIAL BAROMETER the upper section with slightly enlarged scale calibrated in barometric inches incorporating rack-and-pinion adjusting recording pointer set beside a FAHREN'T and CENTIG'E scale mercury thermometer, the upper margin inscribed R.H.C. WILSON, 12 WILSON ST, GRAYS INN, LONDON and the case with Greek style shallow triangular pediment opposing cavetto moulded underside. 32cm (12.5ins) high, 11cm (4.25ins) wide. Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. Robert Henry Capel Wilson is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as working from 12 Wilson Street, Gray's Inn, London 1873-91 and 37 Gough Street, London 1871-80; he joined the firm of Pastorelli and Rapkin in 1893.The design of the current barometer utilises the effect that a change of barometric pressure would have on a sealed disc-shaped corrugated metal chamber. Although the chamber resembles that of an aneroid barometer the instrument utilises fluid (oil) which, via a glass tube rising from the chamber, provides a level from which readings can be taken. It is thought that the patent for this type of barometer was filed in 1863.Condition Report: Instrument is generally in original unrestored condition. The capsule has some visible solder residue suggesting that it may have been repaired/re-sealed at some time however the instrument will respond to variation in pressure (bubble in the column will rise when pressure is increased). The cover for the chamber is missing one screw. Faults otherwise limited to surface grime, very light wear and oxidation of brass fittings. Condition Report Disclaimer

They were leading makers of barographs and aneroid barometers well into the 20th century later merging with Taylor Instruments in 1969.L.H. Leon and Company do not appear to be recorded in the usual sources hence it is likely that they were most likely retail jewellers.Condition Report: All three are in working condition (ie. Respond when 'bag tested') but may require calibration. The thermometer to the dial of the Short and Mason example is undamaged and giving a correct reading. All of the dials are in good original condition but with some tarnishing/discolouration/mellowing to the silvering (the degree of which varies between each instrument). The case example retains original exterior finish in generally good condition with a few spots of discolouration and minor wear only; the other two are more heavily tarnished and worn (see catalogue images). The travelling case for the Short and Mason has overall wear/rubbing but is in sound original condition. Condition Report Disclaimer
