J.H. Steward, 406 Strand, London, a Victorian 'Wet and Dry' travelling/table thermometer, raised on a stand, original fitted case, 18cm James Henry Steward established his business in London in 1852, as a maker and retailer of optical, scientific, military and surveying instruments. In the mid 1800s he became the optician to Her Majesty's Government and the National Rifle, and National Artillery Associations. Steward died in 1896. J. H. Steward Ltd was incorporated in 1912 and continued in business until the middle of the 20th century.

RAF Brass, 360 degree, circular Protractor with crossbar, a scientific drawing instrument in its original green felt lined mahogany box, both the mahogany box and brass protractor made for the Royal Air Force by A. West & Partners, 91 York Street, Westminster, central London, England, circa 1940. This is a circular lacquered brass protractor in its fitted green baize lined mahogany carrying case with hinged mahogany cover having breadboard ends to prevent warping of the wood. (At one time there were at least three mahogany block screwed or nailed into the green baize wooden box to secure the protractor in place when it was being transported. The markings for that are quite clear.) The box contains this scientific drawing instrument, a 23 cm diameter (9.2â€) circle of brass containing a full 360 degrees, marked in 10 degree intervals twice and divided into half degree measurements. The brass cross bar is marked indicating it was made for use by the Main Drawing Office of the Royal Air Force by A. West & Partners Ltd., 91 York Street, Westminster (London, England). The ends of the circle as well as one side of the crossbar is beveled down to fit easily against the map or chart one is examining. There are two rows of degree measurements, the outer row contains the full 360 degrees demarcated in 10 degree intervals while the inner scale contains four individual quadrant measurement from 0-90 degrees also in 10 degree pieces and divided on the outermost edge into half degree sections, serving both measurement scales. {Such instruments were made in this form back into the Victorian era of the 19th century, and this instrument could have been made by A. West & Partners earlier in the 20th century and repurposed for the RAF during WWII.} It is a navigational protractor lacking the four cardinal points shown, a 0 - 360 degree scale, and four 0 - 90 degree scales in the quadrants. In the Air Force this instrument would aid in navigation: To lay out a course or bearing; To read off a course or bearing; To determine angle or direction between two points on a map; To find magnetic course or bearing from True; To fix positions by angle; To plot lines of position, and many other aeronautical functions. Condition: Appears to be in fine condition with most of its lacquer intact, some patchy darkening of the patina of the brass and few scratches. The box is in good condition, missing some of the wooden holding pieces for the instrument and the green felt lining disrupted in many areas, especially at the edges. c. C. 1940

English, c.1743, unsigned but by Cuff, the square solid mahogany plate with a rotating centre mounted to the front with a brass flange into which screws the main body of the microscope constructed of brass with leather covering, a drawer tube has a mount at the front onto which fits the Wilson-type screw barrel microscope, at the rear of the microscope is a single condenser lens in a brass frame and the adjustable mirror in a brass-bound frame, with a sharkskin covered case lined with green silk velvet with 6 objectives, handle for the Wilson microscope, talk box, tweezers, mahogany plate 20cm x 20cm.FootnotesAccording to Clay & Court, in their book, ‘The History of the microscope’ an identical instrument belonged to George the III[i] and formed part of the Frank Crisp Collection, which after Crisp's death, was sold at Stevens Auctions in 1925. The microscope was bought at the sale by the Science Museum and is now in their collections [ii].The Cuff microscope, now in the science museum collection, is described in great depth by Clay & Court on pages 215-217, of their book, and includes an image of an identical instrument that they refer to as ‘Cuff Solar, First Form’, Clay and Court go on to state “The Solar Microscope.-Cuff appears to have been the originator of this form of solar microscope in which the tube was fixed, and the motion of the sun in the Heavens was allowed for by adjusting the mirror. One of the original forms of solar microscopes of Cuff’s make is illustrated in fig 1.48. It is mounted on a mahogany plate which I about eight inches square….”.Clay and Court also allude to an original document held in the British Museum, dated 1743, in which Cuff claims “ I added a mirror to an ingenious suggestion of a friend who had introduced me to Dr. Leiberkuhn, and with the assistance of several Gentlemen of the greatest understanding and ability, I had been able to alter and improve it from time to time”.John Cuff (c. 1708 – c. 1772) was an important English scientific instrument maker during the 18th Century. Although he made all types of instruments today he is best known for his contribution to microscope design. In particular with his Solar or Camera Obscura microscope and his double microscope that became known as the ‘Cuff-type’.Unfortunately, Cuff was apparently not much of a businessman. Despite his ability, expertise, and patronage of the naturalist Henry Baker in 1750 he had to declare himself bankrupt [iii], just a year after, the main competitor of his, Benjamin Martin, opened a shop next door.[i] from Clay & Court s book ‘The History of the Microscope’, from the Preface.[ii] Science Museum South Kensington, London collection, inv.no.

An Important 18th Century Cumming's Pattern Cutting Engine or Microtome,Possibly French, c.1770, unsigned, the body of the instrument is made of brass tube finished on the oustside with a black and mottled red fired enamel to simulate tortoiseshell, at the bottom is a lacquered brass end with a wheel engraved with a scale on a fine steel thread, as the wheel is turned the specimen is raised in front of the blade at the other end, the scale is marked against the brass stop next to the wheel, at the other end is the rotating elliptical blade, this is rotated by turning the polished lignum handle, two knurled wheel at the side are used to hold the blade in place and stop rotation, the other is used to hod the specimen push rod securely in the body of the instrument, the cutting engine comes in its original Fine red Moroccan leather-covered case lined to the inside with red chamois leather, in the case, there is the original shaped stone for sharpening the elliptical blade, a glass slide, a cut-glass bottle with a stopper and another similar but taller with a silver cap, the case 17.4cm wide Footnotes: The Cumming's Cutting Engine - The instrument that changed microscopy. In 1770 a book was published by John Hill (b.1714 – d.1755) on the structure of wood as examined under the microscope. In this book ‘The Construction of Timber from its Early Growth, Explained by the Microscope’, Hill illustrated finely cut sections of wood which were only made possible due to the recent invention of cutting engine or microtome designed and built by Alexander Cumming (ca.1743 – d.1814). This instrument allowed thin sections to be cut so that light could pass through enabling, for the first time, microscopists to see the cell structure of plants. This simple step revolutionised the use of the microscope into a serious scientific instrument. It was George Adams,, then, maker of scientific instruments to King George III, who before this pivotal moment had lamented that the interest in the microscope had waned, famously stating of microscopy “either satisfied with the discoveries already made … or tired by its own exertionsâ€, after Hill's book was published Adams went on to say “So important a subject soon revived the ardor for microscopic pursuits, which seems to have been increasing ever sinceâ€. From Hill’s book, it was stated that Mr. Cummings had made two or three of his cutting engines, the design was then passed to Ramsden who made them commercially, one of which resides today in the collection of the Oxford Science Museum. The Cumming's Pattern Cutting Engine proved difficult to use as keeping the curved blade sharp was a problem. It doesn't appear to have been a great commercial success with only a few instruments surviving today. However, the value of these sections that could be produced for microscopy was now realised and new microtomes were designed and produced by a number of scientific instrument makers. These instruments were easier to use and produced better results consigning the Cumming's Pattern Cutting Engine to history. The design of the instrument offered here is particularly interesting and worth considering. Unlike the existing English instrument by Ramsden this instrument appears to be French in construction: the box is very typically continental with the inside lined with red chamois leather; the instrument has some typically French features with the double knurling of the brass adjusting wheels; the way the lignum handle is turned suggests there may well be Dutch influence. As far as we are aware this is the first time a Cummings Cutting engine has ever been offered for sale at auction.

A FINE VICTORIAN MAHOGANY LONGCASE REGULATORThomas Armstong and Brothers, Manchester, late 19th centuryThe very substantial eight-day four double-screwed pillar movement with 1 inch diameter pillars and quarter-inch thick plates measuring 8.375 by 7.25 inches enclosing wheel train with high wheel/pinion counts, six spoke wheel crossings throughout, Harrisons maintaining power and deadbeat escapement incorporating agate pallets set between twin A-frames, regulated by mercury jar compensated seconds pendulum incorporating wide jaw suspension and hanging from a brass bracket screwed to the case backboard, the 12 inch circular silvered brass dial with subsidiary seconds engraved Regulator to apex over Roman numeral hour dial and signed Tho's Armstrong &, Bro's, Manchester to centre within outer Arabic minute track, with blued steel hands and canted silvered bezel to circumference, the arched case with pendulum hanging access flap to top over arch-glazed door enclosing fine foliate scroll carved and pierced apron beneath dial mirror backboard, on plinth base with cavetto top moulding over recessed flame figured front panel flanked by canted angles on moulded skirt.193cm (76ins) high, 51cm (20ins) wide, 33cm (13ins) deep. Provenance: The Selwyn Demmy Collection. The firm of Thomas Armstrong and Brothers of Manchester can trace its roots back to Joseph Armstrong who established himself as a jeweller and silversmith at 88 Deansgate, Manchester in 1825. By 1851 Joseph's eldest son, Thomas, had succeeded him, and was listed as head of the firm (working in the clock and watch department) in the 1861 Census. By 1868 Thomas had been joined by his brother George Booth Armstrong and the business was re-named 'Thomas Armstrong and brother'. The business continued trading as opticians and makers/suppliers of barometers, scientific instruments and clockmakers both from Manchester and Liverpool until 1965 when they were taken over by Harrisons opticians.The movement of the current lot is notable in being of particularly heavy construction with high wheel/pinion counts. The escapement is also unusual in having pallets apparently made entirely from agate supported between twin 'A' shaped frames.Condition Report: Movement is in fine relatively clean original working condition although a precautionary gentle clean and service is advised if intending to put into long term service. The pendulum is in good original condition with good to the mercury and with light/minimal oxidation/staining to the inside of the glass canister. The dial has some slight rubbing/scratching around the winding hole and some light concentric wear/rubbing to the centre of the hour dial, the dial plate therefore would benefit from being re-silvered which would remove these light surface defects. The case has some front-to-back shrinkage cracking as well as other minor evidence of movement to the arch of the case - this is relatively minor but noticeable. The interior of the case is in fine condition including the carved apron. The front door has two small veneer chips to the front left edge of the frame and the skirting to the left hand side of the base is loose otherwise the case is in fine original condition with faults very much limited to minor bumps, scuffs and blemishes commensurate with an easy life.Regulator is complete with original weight, mercury jar pendulum, a crank winder and a case key.  Condition Report Disclaimer

A VICTORIAN OAK MERCURY 'ADMIRAL FITZROY'S STORM BAROMETER'Negretti and Zambra, London, circa 1870The arched bevel-glazed double ceramic Vernier scales flanking the large bore mercury tube, each calibrated in barometric inches and with the usual observations, the lower margins annotated ADD ONE TENTH FOR, EACH HUNDRED, FEET ABOVE, THE SEA and 10 A.M YESTERDAY and 10 A.M TO DAY over PATENT No. 1481 and with signature NEGRETTI & ZAMBRA, INSTRUMENT MAKERS, TO HER MAJESTY, HOLBORN VIADUCT E.C., 122 REGENT ST. W, & 59 CORNHILL E.C., LONDON to upper margin, the apex of the arch further inscribed ADMIRAL FITZROY'S, STORM BAROMETER., the trunk with Vernier setting squares to throat above applied glazed mercury tube Fahrenheit scale thermometer further signed NEGRETTI & ZAMBRA, LONDON to upper margin and with ogee moulded crests to the upper and lower rails, the base with rectangular ogee moulded cistern cover over conforming base moulding with level adjustment screw to underside.102cm (40ins) high. Provenance: The Selwyn Demmy Collection. 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 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: The tube is filled with no apparent airlocks and both Vernier slides are fully operational however there is only one key present. The arched signature plate has some slight hairline cracking to the lower right hand corner which can only really be seen on very close examination being behind the bevel cut of the glass. The thermometer is in good condition although the tube is probably a replacement. The case is in good original condition with only minor bumps, scuffs and other age related blemishes. Condition Report Disclaimer

A FINE VICTORIAN LACQUERED BRASS FORTIN-TYPE LABORATORY MERCURY STICK BAROMETERNegretti and Zambra, London, late 19th centuryThe instrument with slender square section case pierced with a vertical slot to reveal the tube incorporating sliding silvered Vernier slide reading against silvered scale calibrated in barometric inches to the right and millibars to the left beneath serial number 1838 to upper margin, the shaft with Vernier adjustment disc to right over signature NEGRETTI & ZAMBRA, Scientific Instrument Makers to Her Majesty, LONDON to throat and applied mercury tube thermometer with large bulb within brass protective housing and Fahrenheit scale inscribed directly onto the tube, the base with square glass chamber enclosing mercury and incorporating inverted ivory level pointer to interior clamped between horizontal plates over cylindrical chamber and adjustment screw to base, mounted via a brass ring to top and base collar-bracket with triple securing screws onto a rectangular moulded oak panel applied with an ivorine plate further inscribed NEGRETTI & ZAMBRA, Scientific Instrument Makers, to Her Majesty, LONDON fitted into a rectangular cabinet with moulded cornice over rectangular bevel-glazed door.The instrument 104cm (45ins) high; the cabinet 140cm (55ins) high, 26cm (10.25ins) wide, 19cm (7.5ins) deep. Provenance: The Selwyn Demmy Collection. 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. This particular type of barometer provides an accurate reading hence was generally adopted for laboratory use throughout the 19th and early 20th centuries.Condition Report: Instrument is filled with mercury and provides a good reading with no apparent airlocks. The silvering to the scales is in good condition with only minor discolouration/mellowing and the Vernier slide is operational. The brass case is in good condition although has probably been polished at some point (original lacquer removed) and the finish is generally a little dull/oxidised. The cabinet no longer has its original clasp for the door (has been substituted for a pivoted hook clasp) and has some noticeable bumps and scuffs to the exterior otherwise is in sound original condition. Condition Report Disclaimer

A REGENCY SHAGREEN COVERED 1.75 INCH NINE-DRAW TELESCOPEBate, London, early 19th centurySigned Bate, London and inscribed to adjust by sliding in the second draw to final draw, with shuttered eyepiece, brass end cap and shagreen-covered grip, with leather carrying case; together with a 1 inch three-draw telescope, unsigned, 19th century, with shuttered eyepiece, leather covered grip and protective case, (2).The telescope by Bate 105cm (41.25ins) long extended, 16.5cm (6.5ins) long closed. The first telescope in the current lot is almost certainly by Robert Brettell Bate who is recorded in Clifton, Gloria Directory of British Scientific Instrument Makers 1550-1851 as working from Poultry, London 1808-42 and then 33 Royal Exchange 1846-47. Bate was known as a maker of all types of instrument however was celebrated for his nautical instruments including marine barometers and latterly was appointed Instrument-maker to Her Majesty s Honourable Boards if Excise and Customs.Condition Report: The optics of the Bate telescope are in good condition albeit a little dirty; the instrument will focus and provides a good clear image with strong magnification. The draws appear free form noticeable denting and fit well with no sagging evidence when the instrument is fully extended. The brass retains some of its original lacquer finish, the shagreen is complete with nio losses however has opened along the join and has noticeable wrinkling. The objective end cap is present but is currently lodged in the end of the leather case. The leather case is worn and is lacking its strap; the cap is also probably a later replacement.The second telescope is in sound original condition with no noticeable dents to the draws and retaining much of the original lacquer finish to the brass. The optics are a little dirty but will focus. The leather cover to the grip is loose but complete with no losses so probably can be re-attached. The outer leather case is in poor condition. Condition Report Disclaimer

Y A FINE WILLIAM III BRASS MOUNTED EBONY TABLE CLOCKWilliam Jourdain, London, circa 1700The five finned pillar bell striking movement with verge escapement regulated by short bob pendulum and inside rack for the hour striking mechanism, the backplate signed W. Jourdain, London to the symmetrical foliate scroll engraved backplate centred with a leafy basket and with herringbone border, the 7 inch square brass dial with canted border shaped false bob aperture further signed W. Jourdain, London to a recessed silvered plate behind and calendar aperture to the finely matted centre within applied silvered Roman numeral chapter ring with cruciform half hour markers and Arabic five minutes to outer track, with pierced steel hands, winged cherub head cast spandrels to angles and N/S strike/silent selection switch at three o`clock, the case with elaborate repousse double basket top surmount with fine twin cherub cast handle to the profile mask medallion scroll centred pierced upper tier, the lower tier with relief panel of St. George slaying the dragon flanked by figural military trophies within a conforming cherub and scroll decorated field and flanked by unusual gilt urn finials with tall baluster spires, the front applied with scroll pierced gilt repousse mounts to the frame of the door, the sides with glazed lozenge apertures over rectangular windows, the rear with rectangular glazed door set within the frame of the case, on complex moulded shallow skirt base with cast claw feet. 42cm (16.5ins) high with handle down, 27cm (10.5ins) wide, 17cm (6.75ins) deep. Provenance: the property of a private collector, north London; purchased at Woolley and Wallis sale of Clocks, Pocket Watches, Barometers & Scientific Instruments 26th October 2010 (lot 138) for £6,500 hammer. The life and work of William Jordain and his successors is recorded in Ponsford, Clive N.THE JOURDAIN FAMILY OF SPITALFIELDS, LONDON, SPECIALISTS IN CHIME AND MUSICAL WORK published in the September 2007 issue of Antiquarian Horology (Vol. XXX number III, pages 381-99). Ponsford notes that William Jourdain was born in Dieppe in around 1665 to David Jourdain a Huguenot. In 1686 the family fled across the channel to escape persecution following the Revocation of the Edict of Nantes, and by 1688 the family had settled in London with William Jourdain being admitted to the congregation of the French Church of Threadneedle Street. William Jourdain married his cousin, Anne Le Sturgeon (with whom he had ten children) in 1695 and set-up business as a clockmaker in Spitalfields. After the death of Anne William Jourdain married his second wife, Suzanne Savoy in 1712 who again he outlived allowing him to marry his third wife Susanne Savoy in 1741. William Jourdain died in 1747 leaving the business to his son of the same name who continued in his father's footsteps until he was admitted to William Sutton's Hospital, near Smithfield in 1778 where he remained until his death in 1782.William Jourdain, like many highly skilled Huguenot immigrant craftsmen, apparently never gained his freedom of the Clockmaker's Company. However this did not seem to hinder him in his work as surviving examples demonstrate a high quality approach, often incorporating complications such as musical work and highly decorated cases. The highly decorative nature of the case of the current lot reflects Jourdains 'high-style Huguenot' approach and interestingly can be directly compared to an example housing a movement and dial by Langley Bradley which was sold in these rooms on Wednesday 4th December 2013 (lot 173). The engraving to the backplate is well executed and most likely by a fellow Huguenot being perhaps the same individual who executed the backplate for a clock by Simon DeCharmes which is illustrated in Dzik, Sunny ENGRAVING ON ENGLISH TABLE CLOCKS - Art on a Canvas of Brass 1660-1800 on page 245 (Figure 14.3).Condition Report: The movement is in clean working condition. A series of filled holes to the upper left hand margin of the plates suggests that a pull-quarter repeat mechanism was fitted at some time which is no longer present. The escapement wheelwork has either been re-pinioned or replaced and the lower potance is also a replacement however the top potance, backcock and apron would appear to be original hence the escapement appears not to be a reconversion. Indeed the position of the internal rack for the striking mechanism has most likely deterred conversion to anchor escapement in the past. The upper two wheel of the strike train have been re-pinioned otherwise movement appears to be original and in good condition. The dial is in fine clean condition with strong gilding (although it has possibly been regilded at some point). The chapter ring has some very light concentric rubbing to the silvering; the hour hand may be a well-made replacement.The case is generally in good original condition with no visible damage of losses to the 'double-basket' superstructure; the finials also appear free from damage. The front door has sections missing from the repousse mounts to each end of the upper and lower rails. The right hand mount has a small loss to the lower edge and the left hand has three breaks and a small loss. The front door hinges and lock have been replaced and there is a small veneer loss to the lower right hand corner of the dial mask (where the veneer overlaps the dial plate). The rear door retains its original hinges and lock, the veneers exhibit numerous small historic holes indicating that the repousse mounts were also once fitted to the rear door but are now no longer present. The sides are in good condition although there are two small blemishes to the rear of the left hand side from where the pins securing the rear door hinges have pierced the veneers. Faults to the case are otherwise very much limited to minor shrinkage and a few other very slight age related blemishes.Clock has a case key but no winder. Condition Report Disclaimer

W., LONDON. to centre.The instrument 102cm (40ins) high; the wall panel 103cm (44ins) high, 14cm (5.5ins) wide. Provenance: The Selwyn Demmy Collection. 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. This particular type of barometer provides an accurate reading hence was generally adopted for laboratory use throughout the 19th and early 20th centuries. Condition Report: Instrument is filled with mercury and provides a good reading with no apparent airlocks. The silvering to the scales has discolouration/mellowing, the Vernier slide is operational. The brass case is in sound condition but has patchy strong discolouration and wear to the original lacquered finishes. The back panel has some historic age related bumps, scuffs shrinkage and discolouration/blooming to the finish. Condition Report Disclaimer

A VICTORIAN PATINATED BRASS SEXTANT Adie and Son, Edinburgh, mid 19th century The pierced diamond 'lattice' pattern frame with pivoted arm mounted with mirror opposing hinged magnification lens over aperture for reading the fine silver inset brass Vernier scale signed ADIE & SON, EDINBURGH, No. 210 and initialled J.H., with two sets of hinged filters, brass telescopic sighting tube and wooden grip to rear of frame, the fitted keystone-shaped mahogany box with two additional sighting tubes, a telescope eyepiece slider and a eyepiece filter.The box 35.5cm (14ins) wide, 26.5cm (10.5ins) deep, 12.5cm (5ins) high. Alexander Adie is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as born 1775 and dying in 1858. Adie was the nephew of John Miller, one of the leading Scottish makers of Scientific Instruments in the 18th century and was apprenticed to him in 1789. In 1804 they formed the partnership of Miller and Adie which continued until the death of John Miller in 1815. Adie continued the business alone specialising in meteorological instruments obtaining a patent in 1818 for his air barometer or sympiesometer. In recognition of this invention he was elected a Fellow of the Royal Society of Edinburgh in 1819. He was appointed optician to William IV and later Queen Victoria after forming a partnership with his son, John, in 1835 to form Adie & Son. Father and Son worked together from Princess Street, Edinburgh until 1857 when the business was continued under Richard Adie who relocated the firm to Hanover Street in 1877.Condition Report: Optics are complete with the exception of one small filter and intact however there is some internal condensation/deposits within the tube(s) which affects the clarity of the viewed image. The filters and mirrors appear complete and free from damage. The Vernier is operational with minimal wear to the scale and the magnifier is working. The frame has verdigris spotting coming through the japanning as well as age related wear but is undamaged. The case is generally in good original condition but with some age related shrinkage, bumps and scuffs; there is no key for the box. Condition Report Disclaimer

A VICTORIAN OAK MERCURY 'ADMIRAL FITZROY'S STORM BAROMETER'Negretti and Zambra, London, circa 1870The arched bevel-glazed single ceramic Vernier scale to the right of the large bore mercury tube calibrated in barometric inches and with the usual observations, the lower margins annotated ADD ONE TENTH FOR, EACH HUNDRED, FEET ABOVE, THE SEA over PATENT No. 2809 and with signature NEGRETTI & ZAMBRA, INSTRUMENT MAKERS, TO HER MAJESTY, HOLBORN VIADUCT E.C., 122 REGENT ST.

The firm became one of the most prolific makers of scientific instruments and continued trading well into the 20th century.The current lot is an 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. Interestingly the scale only incorporates one Vernier scale (rather than usual the double scale) hence recording daily change in barometric pressure would have had to be done by taking notes rather than using the second scale. 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: The tube is filled with no apparent airlocks and both Vernier slide is fully operational. The scales have some slight overall crazing and the left panel of the scale has a small hairline crack across the top right hand corner. The thermometer is in good working condition however the scale has overall stained crazing. The case is in good original condition with only minor bumps, scuffs and other age related blemishes. Condition Report Disclaimer

A RARE VICTORIAN WROUGHT IRON AND BRASS WAYWISER OR HODOMETERNegretti and Zambra, London, mid to late 19th centuryWith 22.75 inch diameter iron-rimmed solid-spoked wheel pivoted between forks fitted with rectangular oxidised brass case enclosing worm gear for the circular revolving register calibrated from zero to 220 YARDS with the centre cut with a sector revealing scales for miles and furlongs reading against an integral fixed pointer, set behind pivoted cover incorporation circular glazed porthole and engraved NEGRETTI AND ZAMBRA, LONDON to lower margin, with iron upright forged in one-piece with the forks terminating with a cross-piece handle fitted with wooden grips.90cm (35.5ins) high, 18cm (7ins) wide overall. 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.Condition Report: Instrument is in fine complete original working condition retaining original finishes to the brass mechanism albeit in dirty/discoloured condition. The ironwork has been repainted in satin black and the rim of the wheel has evidence of historic rusting (is pitted) to a section of the rim (approx. 9 ins in length) commensurate with the item being stored with the rim on a damp floor for a period of time. This pitting, although noticeable through the paint, does not affect the operation of the instrument. Condition Report Disclaimer

A Rare Richard Cushee 'Mr Neale's Patent' 12-inch celestial globe, English, circa 1730,signed A New Celestial GLOBE By R Cushee 1730, the brass frame mounted with geared lunar apparatus devised and made by John Neale, brass meridian engraved with four quadrant degree scales, horizontal ring engraved with calendar and points of the compass, with operating wheel and gearing at the base, raised on turned brass column and domes base, together with a framed plate illustrating the celestial and terrestrial globe from a plate in The New Dictionary of Art and Science, 23in (59cm) high; framed plate 20in x 14in (51cm x 35.5cm) (2)Footnotes:Provenance:Christie's, London, 1967.The Stephen Edell Collection.Neale's globe accessory was a geared version of a manual device presented to the Royal Society in 1747 by James Ferguson to show the apparent geocentric movements of the Moon. In it 'a simple wheel train at the top of the globe coupled the globe's rotation to that of a quadrantal moon-arm and thereby caused the moon to move relative to the globe and a stationary sun' (King & Millburn 196-7). Exactly when Neale devised it is uncertain as his only patent, obtained in 1744 was for a form of coaxial orrery. It was perhaps by association with this patent that Neale's globes were referred to as 'patent globes'The earliest description of Neale's device is in Edward Moore, A Supplement to all former treatises on the use of the globes, render'd necesssary from the late improvements exhibited to the public on mr.Neale's patent globes. In two parts ..., London 1751. printed: and sold by M. Cooper, in Pater-Noster-Row; B. Cole, mathematical instrument maker, in Fleet Street, and by the patentee, at his House in Leadenhall-Street. It was described again in a long advertisement in Daniel Fenning; New & easy guide to the use of the Globes, London 1754 wherein a ten page description he states that 3in and 12in models were made respectively for six and twelve guineas.The 'patent globes' were also illustrated in A New and Complete Dictionary of Arts and Sciences: Comprehending All the Branches of Useful Knowledge ... Illustrated with Above Three Hundred Copper-Plates, Curiously Engraved by Mr. Jefferys ... by a Society of Gentlemen, London: 1754-1755.Only the lunar apparatus was made by Neale, the globes being supplied by Richard Cushee, a close neighbour of Neale's in Fleet Street. A pair of the 3in model with globes by Cushee fitted with Neale's device (the terrestrial dated 1731), are held in the Science Museum, London (See Calvert N° 5).John Neale (c. 1724-post 1783), was a watchmaker freed in the Skinners' Company in 1718 having been apprenticed to Jonathan Houillière. He lived in Leadenhall Street, and had a shop at the 'King's Arms and Dial', St Dunstan's, Fleet Street. He bound eleven apprentices between 1742 and 1758 and for a period employed James Watt. Neale made other instruments incorporating geared mechanisms (a waywiser is known), and also gave private lecture courses on the globes and electricity either in the homes of the clients or in his own dining room. He declared bankruptcy twice, in 1750 and 1758, but was a Common Councillor for the Ward of Aldersgate Within from 1768-83.Literature:H. R.

A Fine and Rare Thomas Blunt Combined Planetarium, Lunarium, and Tellurium, English, early 19th century,the drum signed T. Blunt. London, the 9-inch cylindrical brass drum containing hand-cranked gearing for operating the planetarium, tellurium, and lunarium, the top-plate engraved with zodiac degree and calendar scales centred by stylised floral and palmette motifs, the circumference cut with teeth, the mechanism operated by winding handle to the side of the drum.When set up as a tellurium, complete with brass sphere representing the sun, and a John Newton 2 1/2-inch terrestrial globe mounted within a silver meridian.When set up as a lunarium, with similar construction to the tellurium with models representing the Earth and the moon, a thin rod protruding from the Earth tracks the orbit ring of the moon, the models above a silver-plated meridian and disc displaying the signs of the zodiac and the 29 1/2-day lunar cycle, marked PERIGEE.When set up as a planetarium, with models representing Mercury, Venus, the Earth, Mars, Jupiter, Saturn and Uranus. The Earth, Jupiter, Saturn and Uranus each with brass subsidiary arms representing the moon or moons of each planet.The whole raised on a turned brass column with folding tripod base, in 21in (53.5cm) high fitted mahogany case with brass holding handles to either side, 19 1/2in (49.5cm) high as tellurium Footnotes:Provenance:The Rachel Lambert Mellon CollectionEx-Lot 1070, Sotheby's, New York, 21 November 2014.The present orrery is a fine example combining three mechanical models for the motions of the Earth around the sun (tellurium), the moon around the Earth (lunarium), and of the solar system (planetarium). It is rare for an orrery to incorporate all three models, with many contemporaries producing only a tellurium and planetarium.Thomas Blunt (d. 1823) founded the prominent family business Blunt & Son (also operating as Blunt T. & T.) on Cornhill, London in 1801, with his sons and apprentices Thomas, Edward, and William. Though a member of the Guild of Spectaclemakers from 1771, Blunt was known for producing an extensive variety of scientific, medical and optical instruments over the course of his career. In addition to orreries, Blunt and his business were known for their globes, microscopes, thermometers, and barometers, among other instruments.Prior to establishing his own firm, Blunt was apprenticed in 1760 to the renowned instrument maker Edward Nairne, and was later appointed as instrument maker to King George III. Blunt's skill under Nairne's mentorship was eventually established formally as the two formed the partnership of Nairne & Blunt by 1791. The partnership of Thomas Blunt with his son Thomas is thought to have coincided with the retirement of Edward Nairne from the profession.This lot is subject to the following lot symbols: Y ФY Subject to CITES regulations when exporting items outside of the EU, see clause 13.Ф This lot contains or is made of ivory.

NORTH-WEST PASSAGE – FIRST ROSS EXPEDITIONTwo orders, signed ('JW Croker') as Secretary to the Admiralty to Captain Ross, R.N. ('Sir'), the first directing a number of Royal Marines to be selected from the Woolwich division '...for the ships about to proceed on the Northern Expedition of discovery, viz. for the Isabella and Dorothea...'; the second with reference to '...the vessels about to proceed to the Arctic seas...', advising him that charts '...for the use of the Sloop you command and the Alexander, with telescopes for the Boats and for looking out from the mast heads...' will be sent and advising they will reimburse him for the purchase of '...shot for procuring game... both of large and small as you shall think necessary...', the first docketed for filing, 3 pages, watermarks of Britannia and 'G. Pike/1815', creased at folds, light dust-staining and marks, narrow paper window mounts to lower half of each, folio (314 x 198mm.), Admiralty Office, 25 March and 2 April 1818Footnotes:'ABOUT TO PROCEED ON THE NORTHERN EXPEDITION OF DISCOVERY': BARROW'S ADMIRALTY SUPPLIES CAPTAIN JOHN ROSS WITH MEN AND EQUIPMENT FOR HIS FIRST ATTEMPT TO DISCOVER THE NORTH-WEST PASSAGE.The great impetus to discover the Northwest Passage was largely due to the efforts of John Barrow, second secretary of the Admiralty from 1804-1845. Following the Napoleonic Wars, he employed the navy, as shown here, in a series of expeditions to discover a valuable trade route from the North Atlantic via the Arctic to the Pacific Ocean. These orders refer to the first of such expeditions. Four ships departed with this purpose on 25 April 1818 and sailed up the east coast to Lerwick where they parted company – the Isabella and the Alexander under Captain John Ross were intended to proceed together in a north-westerly direction through Davis Strait, the other two, the Dorothea and the Trent under the command of Lieutenant William Edward Parry were to proceed due north through the Spitzbergen Seas. The Isabella and the Alexander had been adapted at Deptford for the special conditions of Arctic service and were well stocked with suitable provisions and the latest in scientific instruments.The voyage ended ignominiously when Ross was deceived by a mirage and declared the passage blocked by a range of mountains, which he named the Croker Mountains after the signatory of our orders. He returned home to a barrage of very public criticism which his reputation never really recovered from. He made a second unsuccessful attempt in 1829 aboard the steam vessel Victory, was passed over for Franklin's doomed expedition of 1845 but commanded a Franklin relief expedition in 1849, funded by a combination of his own money, that of gin-magnate Sir Felix Booth (who had also sponsored the Victory), and public subscription. Despite his dismal relations with the Admiralty, in terms of his peaceful interactions with the Inuit people, his accurate chart-making and, above all, his success in keeping his men safe on his expeditions, it has been argued that Ross' long career was one of the most successful of the Arctic explorers.For further information on this lot please visit Bonhams.com
