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

AN UNUSUAL VICTORIAN CARVED OAK MERCURY WHEEL BAROMETER  SINGER, FROME, THIRD QUARTER OF THE 19th CENTURYThe 8 inch circular silvered register engraved with starburst and signed SINGER, FROME to the centre within scale calibrated in barometric inches and with the usual weather observations to outer track, set behind convex glazed brass bezel, the case carved with entwined branches with leaves and acorns around a panel applied Fahrenheit scale mercury tube glazed thermometer incorporating leafy crests to top and bottom to the upright with the branches continuing around the dial and with further left motif to the base incorporating recording hand adjustment square, (unrestored, lacking hands).101.5cm (40ins) high; 33cm (13ins) wide. Provenance: The archive collection of Barometer World Museum, Merton, Devon. Singer of Frome does not appear to be recorded in the usual sources however online sources note them as art metalworkers and founders of bronze (cire perdue) working from 'Frome Art Works' from circa 1848; It would appear that they mainly undertook commissions for ecclesiastical works. 

AN UNUSUAL MERCURY TUBE DEMONSTRATION STICK BAROMETER IN BOW-FRONTED GLAZED MAHOGANY CASECHADBURN, LIVERPOOL, CIRCA 1860With fully exposed tube suspended from an ornamental scroll-shaped lacquered brass bracket at the top with the base immersed in a simple cylindrical glass cistern with circular cap resting on a brass collar and supported from underneath by a disc applied to conforming bracket, the upper section with generous silvered twin Vernier scales calibrated in barometric inches and labelled Registered 8am and Registered 8pm respectively beneath signature CHADBURN, OPTICIAN &, Instrument Maker, To HRH Prince Albert, Lord St. Liverpool, to upper margin, contained in a mahogany D-shaped case with stepped inverted ogee moulded top over full height half-round glazed front door and conforming moulded base.107cm high (42ins) high, 22cm (8.5ins) wide, 18.5cm (7.25ins) deep. Provenance: The Selwyn Demmy collection. Chadburn Brothers are recorded in Banfield, Edwin, BAROMETER MAKERS AND RETAILERS 1660-1900 as 'notable makers' working from Albion Works, 26 Nursery Road, Sheffield and 71 Lord Street, Liverpool circa 1837-75.The current lot appears to have been designed to allow the working principles of a barometer to be clearly seen and presented in a high-quality manner. From this it would be reasonable to suggest that the instrument was perhaps made for showroom use, a thought that is backed-up by the full signature to the plates, or for a wealthy gentleman's home laboratory. The present barometer can also be fairly accurately dated as the double scales follows Admiral Fitzroy's principles which he first introduced in around 1857, hence the instrument would have been made after that date but before the death of Prince Albert in 1861. 

A FINE OXIDISED BRASS NEWMAN-PATTERN MERCURY STATION BAROMETERJOHN FREDERICK NEWMAN, LONDON, MID 19th CENTURYConstructed with two square section uprights joined at the top with a D-shaped section inset with silvered plate engraved F. NEWMAN, 122 Regent Street, LONDON, over cavetto moulded cornice and central large-bore tube with silvered scale calibrated in millimetres to the left opposing later brass for millibars to the right with rack and pinion adjusted Vernier slide between, the throat with plate engraved with Met Office MO trademark and number 1517 over Vernier adjustment screw and further Met Office plate with calibration note to the right hand upright, the base with substantial cylindrical cistern with band of glazed apertures and incorporating mercury tube Kelvin scale thermometer with bulb immersed in the cistern to left hand side, the instrument suspended via pivoted joint from a scroll-cast bracket with conforming steady bracket to base from an arched caddy-moulded mahogany panel for wall hanging.The board 133cm (52.5ins) high, 20cm (8ins) wide.  Provenance: The exhibition collection of Barometer World Museum, Merton Devon. Acquired direct from the Meteorological Office after withdrawal from use in a Caribbean station believed to be either the Bahamas or Bermuda. John Frederick Newman is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as working at 7 and 8 Lisle Street, London, 1816-25 then 122 Regent Street 1827-62 when the business was taken over by Negretti and Zambra. He made standard and portable barometers for James Clark Ross's Antarctic expeditions (1839-1843) and exhibited at the Great Exhibition at Crystal Palace in 1851. Newman's design of station barometer incorporates movable scales to allow calibration against the mercury level in the cistern which may vary very slightly with changes in temperature. After taking-over the business in 1862 Negretti and Zambra continued making barometers to Newman's design including an example which was sold in these rooms on 2nd October 2019 (lot 41) for £2,600. 

A JAPANNED AND LACQUERED BRASS FORTIN-PATTERN LABORATORY/STATION MERCURY STICK BAROMETERNEGRETTI AND ZAMBRA, LONDON, SECOND QUARTER OF THE 20th CENTURYThe instrument with slender cylindrical case with the upper section fitted with a glass sleeve enclosing silvered scale incorporating vertical slot to reveal the tube and sliding silvered Vernier slide reading against silvered scale calibrated in barometric inches to the right and millibars to the left, the upper margin with Met Office number 2241, the reverse with additional Vernier slide reading against a cm scale calibrated 65-82 divided into tenths to the right opposing signature NEGRETTI & ZAMBRA LONDON to the left, the shaft with Vernier adjustment disc to right over brass plaque inscribed M/2241, STANDARD TEMPERATURE, AT 1000Mb... and applied mercury ABSOLUTE and FAHRENHEIT scale thermometer, the base with cylindrical glass chamber clamped between horizontal plates over cylindrical cistern and adjustment screw to base, (unrestored).109cm (43ins) high including top ring, 9cm (3.5ins) max diameter. Provenance: The archive collection of Barometer World Museum, Merton, Devon; acquired direct from the Meteorological Office. The firm of Negretti & Zambra are recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as being established in 1850 when a partnership between Enrico Negretti and Joseph Warren Zambra was formed. The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is made to the principles laid down by Nicholas Fortin (1750-1831) and incorporates a glazed cistern so that the level can be calibrated via the adjustment screw to the base against an inverted conical ivory cone in the cistern in order to obtain consistency in the readings. 

A FINE SCOTTISH GEORGE II MAHOGANY AND BURR ELM DOMESTIC REGULATOR WITH CENTRE-SECONDS ALEXANDER CUMMING, INVERARAY, CIRCA 1755The substantial five pillar rack striking movement with deadbeat escapement regulated by a later seconds period wood rod 'Ludlam' pendulum with heavy brass faced lenticular bob, bolt-and-shutter maintaining power and six wheel going train, the backplate with aperture cut for the pallets, the 12 inch square single sheet silvered brass Roman numeral dial with blued steel hands and signed Ale:r Cumming INVERARAY to an arched cartouche to centre within chapter ring with Arabic five minutes to outer track and fine scallop shell inhabited foliate scroll engraved decoration to spandrels, in a case with complex moulded dentil cornice, fretwork frieze and turned three-quarter columns to the hood door, the sides with break-arch glazed apertures and quarter columns applied to bargeboards at the rear, the trunk with convex throat over burr elm veneered panel inset break-arch door, the plinth base veneered with conforming rectangular panel over ogee bracket feet.207cm (81.5ins) high, 55cm (21.75ins) wide, 29cm (11.5ins) deep. Provenance: Possibly constructed for Archibald Campbell, the third Duke of Argyll, whilst the maker was working for him at Inveraray circa 1755.Alexander Cumming was born circa 1732 and is believed to have been apprenticed to an Edinburgh based watchmaker. At an early stage his talent for the mechanical was noticed by Lord Milton through whom he is most likely to have ended up working alongside his brother, James, at Inveraray for Archibald Campbell, the third Duke of Argyll during the 1750's. Alexander and James Cumming were commissioned by the Duke to install an organ for his new castle at Inveraray and Alexander was also tasked to produce a clock.Alexander Cumming was a founder member of the Scottish Royal Society in Edinburgh and by 1761 (after the death of Archibald Campbell) he had moved to London possibly through the encouragement of Thomas Grignon. By 1763 Cumming was established in New Bond Street and supplied the first ever recording barometer to George III which is still in the Royal Collection at Buckingham Palace. He was subsequently appointed as an 'expert' by Act of Parliament to assess Harrison's marine timekeepers and in 1766 he published The Elements of Clock and Watch Work. In addition to clockmaking Cumming is also credited with other notable inventions such as the first accurate recording barograph (1766), the microtome - a machine for making extremely thin slices as used in microscope slide-preparation (1770) and an advanced design of flushing toilet which included a trap to prevent odours re-entering the room.By the mid 1790's Alexander Cumming had retired to Penton Place in Pentonville, then a suburb of London, where he wrote a number of essays on mechanical questions. He died at home on 8th March 1814, aged eighty-two, and was buried at St James's Chapel, Pentonville Road, Finsbury, London. The current lot is an interesting and potentially historically significant example of Cumming's early work due to being distinctly experimental in nature and dating to his time at Inveraray. The escapement is perhaps particularly noteworthy as it appears to follow a design by Thomas Grignon which was conceived as an improvement over Graham's deadbeat (see Rees, Abraham Rees's Clocks Watches and Chronometers 1819-20 page 200 and Fig 6). If this is the case then evidence of collaboration between Grignon and Cumming would serve as confirmation of a direct connection with Archabold Campbell due to the fact that the third Duke also commissioned Grignon to produce a clock for presentation to the Royal Society of Arts in London (also see Rees, page 68).  The six-wheel going train is unusual but was probably necessary in a hour-striking clock that was also intended to serve as an accurate timepiece and possible 'test bed' for an improved design of deadbeat escapement. It would seem that the going train was conceived to allow the delivery of a high degree of motive power through the motionwork in order to proportionally minimise the effect of friction (and interference from the strike train during lifting) on the power delivered to the escapement. Indeed the fact that the current lot was designed with a strike train and a 'domestic-friendly' dial layout would strongly suggest that the it was made for a knowledgeable patron who wanted a highly accurate timepiece suitable for domestic use. When this is considered alongside the strong possibility of collaboration between Cumming and Grignon at Inveraray then the most likely patron would have to be Archibald Campbell, third Duke of Argyll. 

A CASED JAPANNED AND LACQUERED BRASS FORTIN-PATTERN LABORATORY/STATION MERCURY STICK BAROMETERUNSIGNED, EARLY TO MID 20th CENTURYThe instrument with slender cylindrical case with the upper section fitted with a glass sleeve enclosing silvered scale incorporating vertical slot to reveal the tube and sliding silvered Vernier slide reading against silvered scale calibrated in barometric inches to the right and millibars to the left, the lower margin inscribed No 1081, the shaft with Vernier adjustment disc to right above applied mercury CENTS and FAH'T scale thermometer, the base with cylindrical glass chamber clamped between horizontal plates over cylindrical cistern and adjustment screw to base, mounted via hook for the top ring and screw clamp at the base onto a rectangular mahogany backboard into a pine framed case with triple panel glazed front door.The cabinet 120cm (47.25ins) high, 18cm (7ins) wide, 12.5cm (5ins) deep. Provenance: The archive collection of Barometer World Museum, Merton, Devon. The current lot is made to the principles laid down by Nicholas Fortin (1750-1831) and incorporates a glazed cistern so that the level can be calibrated via the adjustment screw to the base against an inverted conical ivory cone in the cistern in order to obtain consistency in the readings.Condition Report: Instrument is complete and in original unrestored condition. The tube is filled with mercury however the level will stop around 10mm from the top of the tube when tipped indicating that there is a small amount of air present. The silvering to the scales is a little discoloured and oxidised, the thermometer scale has significant green verdigris deposits/corrosion as does most of the originally lacquered elements of the instrument. The black japanned surfaces are in good original condition with only minor wear etc commensurate with age. The glazed case is intact and free from significant damage however the upper part is discoloured with visible historic mildew deposits and there are areas of minor historic age-related wear. Condition Report Disclaimer

TWO BRASS KEW-PATTERN MERCURY MARINE STICK BAROMETERS ADIE, LONDON AND ADIE, LIVERPOOL, LATE 19th CENTURYEach with slender cylindrical case the first finished in oxidised brass with silvered scale calibrated in barometric inches next to vertical slot revealing the tube and with silvered Vernier slide opposing signature ADIE, LONDON, No. 950, the other black japanned incorporating fully silvered cylindrical scale section signed Adie, Liverpool No. 325 to lower margin, the shafts with Vernier adjustment discs to right, gimbal mount and applied mercury tube Fahrenheit scale thermometers with concealed bulbs, the bases with cylindrical cisterns, (both unrestored the first lacking gimbal yoke, the second lacking tube, both lacking scale glasses), (2).The first 93cm (36.5ins) high, 6.5cm (2.5ins) max diameter; the second 90cm (35.5ins) high, 5cm (2ins) max diameter. Provenance: The archive collection of Barometer World Museum, Merton. Richard (Liverpool) and Patrick Adie (London) were the sons of the celebrated Scottish instruments maker Alexander Adie who is recorded in Goodison, Nicholas English BAROMETERS 1680-1860 as born 1774 and apprenticed to his uncle, the eminent Scottish instrument maker John Miller, in 1789. 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.

A VICTORIAN BRASS KEW-PATTERN MERCURY MARINE STICK BAROMETERADIE, LIVERPOOL AND LONDON, CIRCA 1870 The slender cylindrical case with the upper section incorporating vertical slot to reveal the tube and sliding Vernier reading against silvered scale calibrated in barometric inches positioned to the right and signed ADIE Liverpool No. 375. ADIE London to outer margin, set behind a glass sleeve retained by domed cap at the top, the shaft with Vernier adjustment disc and gimbal wall mount over applied mercury tube Fahrenheit scale thermometer, the base with cylindrical cistern.92cm (36ins) high, 5cm (2ins) diameter.  Richard Adie was the son of the celebrated Scottish instruments maker Alexander Adie who is recorded in Goodison, Nicholas English BAROMETERS 1680-1860 as born 1774 and apprenticed to his uncle, the eminent Scottish instrument maker John Miller, in 1789. 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 (the maker of the current lot) in Liverpool form 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

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 MAHOGANY CASED HOOKE'S OTHEOMETERPHILLIP COLLINS, MERTON, DEVON, LATE 20th CENTURYThe printed paper scale with herringbone border enclosing amplified reversed scale calibrated in barometric inches and with the usual early-type weather observations for both SUMMER and WINTER beneath comments Fair if Fall and Foul if Rise and title HOOKE'S OTHEOMETER within a scroll decorated to surround to upper margin, applied with syphon tube incorporating large silvered sealed bulb part-filled with red-stained oil opposing column open to the atmosphere at the top for reading against the scale to the centre, the lower left hand corner of the scale with explanation passage over oval cartouche inscribed P. Collins, MERTON, the rectangular glazed case cavetto cornice, simple brass slide recording pointer to right hand side and conforming base, the rear with applied paper build label.68.5cm (27ins) high, 21.5cm (8.5ins) wide, 7c, (2.75ins) deep. Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. Within the explanation passage printed to the lower left-hand corner of the paper scale Phillip Collins notes that Robert Hooke's diary for 12th July 1677 records It is now very evident that the Otheometer moves directly opposite to the Barometer. The present instrument is an improved version of the Otheometer as devised/described by Hooke and indicates barometric pressure via the column of fluid in the tube which rises and falls due compressive effect atmospheric pressure has on the air-filled bulb. The large diameter of the bulb in relation to the bore of the tube amplifies the motion of the fluid hence the enlarged scale which is also in reverse as increase in pressure causes the air volume of the air in the bulb to reduce. Hooke derived the name form the Greek othe which means to push, as this is action that atmospheric pressure has on the fluid within the column. A notable fault with Hooke's design is the effect that temperature has on the volume of air in bulb. For this improved model the surface of the chamber has been blown with a second wall enclosing an evacuated jacket around the first, which in-turn has been silvered to reduce the effect sunlight would have on the chamber's internal air temperature; this refinement requires a great deal of skill from the glass blower. 

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.  

A FAITHFUL REPLICA OF TORRICELLI'S EXPERIMENTAL MERCURY BAROMETERPHILLIP COLLINS, LATE 20th CENTURY With two glass tubes set side by side both open at the base and sealed at the top but the right incorporating a bulb, each suspended in ogee-shaped open cistern, the apparatus mounted via three brackets onto a rectangular oak backboard.98cm (38.5cm) high, 9cm (3.5ins) wide, 11cm (4.25ins) deep. Provenance: The exhibition collection of Barometer World Museum, Merton, Devon. In 1641 the mathematician and scientist Evangelista Torricelli (1608-1647) went to Florence to live and work alongside Galileo who, aged 77, was by then completely blind and unfortunately died soon after Torricelli's arrival. On studying his former master's papers Torricelli discovered notes relating to water not being able to be raised any further than around 33 feet with a vacuum pump. On reading this he decided to try the same experiment but with mercury; he soon found that by filling a tube around 36 inches long closed at one end, sealing it with his finger, inverting it and then submersing it into a container filled with mercury before then removing his finger, the level in the tube would then drop to around 29 inches. Torricelli realised that the level of mercury in the tube was being maintained by atmospheric pressure and that this level changed slightly over time. From these experiments in 1643, the first mercury barometer was invented. The present lot is a faithful reconstruction based on Torricelli's illustration reproduced in Banfield, Edwin Antique Barometers, an illustrated survey on page 2 (figure 1.2).

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.

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.

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
