A fine George III mahogany longcase clock with dual Julian and Gregorian calendar indication and deadbeat escapement. George Lindsay with movement attributed to the workshop of George Graham, London, circa 1752. The substantial fully latched five pillar rack and bell striking movement with plates measuring 8.5 x 7.25 inches, deadbeat escapement and currently of month duration with five-wheel trains, the 12 inch brass break-arch dial with dual Julian and Gregorian date of the month apertures and subsidiary seconds dial to the matted centre within applied silvered Roman numeral chapter ring with fleur-de-lys half hour markers and Arabic five minutes to outer track, the angles applied with fine female mask and scroll cast gilt spandrels beneath arch centred with a silvered boss signed George Lindsay, LONDON flanked by dolphin cast mounts, the case with convex sided upstand incorporating brass foliate engraved sound fret infill to frieze and mahogany ball finials above break-arch cavetto cornice and free-standing large diameter columns flanking the hood door, the trunk with break-arch one-piece mahogany door over plain plinth base with moulded double skirt and squab feet, the interior of the case inscribed in pencil 1752 KV, 241 (95ins) excluding top finial, 251cm (99ins) high overall; with a period copy of Thomas Baskett and the Assigns of Robert Basket An Act to amend an Act made in the last Seffion of Parliament (intituled, An Act for regulating the Commencement of the Year, and for correcting the calendar now in Ufe.) 1752. (2). George Lindsay is recorded in Baillie, G.H. Watchmakers & Clockmakers of the World as working in London from circa 1743 until his death in 1776, as well as being a watch and clockmaker Lindsay also produced scientific instruments. In 1743 he published an advertisement for a `Generally Portable` microscope, in another hand written trade pamphlet Lindsay refers to himself as `Watch & Clockmaker to his Royal highness ye Prince of Wales at ye Dial near Catherine Street in ye Strand`. He was later appointed watchmaker to George III, a position he held until his death in 1776. The movement of the current lot with its distinctive substantial bulbous knopped pillars, teardrop shaped pivot cocks for the under dial work and other more subtle details such as the elongated collet for the escape wheel and the suspension cheeks being screwed to the lower edge of the backcock nib, indicates that it originated from the workshop of George Graham. The overall arrangement of the strikework and the impressive nature of the snail/hour wheel assembly is typical of Graham`s work and can be directly compared with numerous examples of his work such as number 777 sold Christie`s King Street, June 1994 (lot 483). The presence of a deadbeat escapement and larger than normal plates is noteworthy suggesting that the current lot may have been devised with further refinements in mind. Originally the movement was made to run for eight-days only and was fitted with bolt and shutter maintaining power (dial has vacant slot at 3 o`clock for the shutter lever and movement has related vacant holes in the plates) however the duration has been increased with by inserting another wheel into each train and reversing the winding pulleys. The bolt-and-shutter maintaining power was removed at this time as it is would be no longer required in a long duration movement. These improvements were probably done early in the clock`s life perhaps even by Lindsay himself however there is no immediate evidence to confirm this. The provision of two date apertures (to give the date of the month according to both the Julian and Gregorian calendars) to the centre of the dial indicates that the current lot was made at the time when the `new` calendar was adopted by Act of Parliament in 1752. By this time the Julian calendar had become inaccurate (due to the error in the estimation of the length of the day) causing difficulties in respect to the synchronisation of the vernal equinox and subsequent calculation of Easter. In order to correct the error twelve days were added to the British calendar at midnight on September 2nd 1752 and the rules for calculating leap years were altered. The Roman Catholic Church had adopted the new calendar in 1582 with most of Continental Europe (under Catholic rule) following shortly afterwards, Great Britain was the last major Western European state to implement the new calendar.

The firm of Negretti and 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 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 designed to record relatively small variations in barometric pressure over a given time in order to provide accurate trends to assist in weather forecasting.

A Regency mahogany sympiesometer, Adie, Edinburgh, circa 1825, With glazed rectangular silvered scale applied with sulphuric acid and hydrogen gas filled syphon tube against a Fahrenheit temperature scale with a separate scale calibrated for the barometric inches adjusted via brass knob slider to the right-hand side of the case, to the left is a Fahrenheit scale mercury thermometer above inscription PATENT, Adie, Edinburgh with sector for the rotating recording disc with serial number No. 1286 beneath, the simple rectangular case with reeded moulded surround, 60cm 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. The sympiesometer was patented by Alexander Adie in 1818 and is essentially an improved version of Robert Hooke`s thermobarometer which he described in a paper presented to the Royal Society in 1668. The hydrogen gas in the syphon tube is affected by both temperature and pressure so the instrument has to be first calibrated by adjusting the moveable barometric scale against the temperature calibrations so that the pointer lines up with the temperature reading on the mercury thermometer to the left of the syphon tube before a reading can be taken from the top of the fluid level. The sympiesometer was conceived as an alternative to the mercury marine barometer as it was smaller thus more portable.

Lot 89
A fine George III green japanned eight-day longcase clock Henry Hindley, York, mid 18th century The four double-baluster turned pillar movement with concealed clicks to the barrels, gravity fed rack and bell striking, long crutch for the original heavy-bob pendulum and six-spoke wheel crossings throughout, the 12 inch brass break-arch dial with subsidiary seconds ring to the richly matted centre within applied silvered Roman numeral chapter ring with Arabic five minutes and signed Hindley, York to lower edge, the angles with rococo scroll cast spandrels, beneath arch with large diameter calendar ring flanked by conforming mounts, in a green ground gilt decorated case with concave sided pediment above three-quarter pilasters to hood door, break-arch trunk door decorated in raised polychrome and gilt with oriental figures within a terrace garden landscape above a European man o’ war, the plinth similarly decorated with a leaping dear above moulded double skirt base, 236cm (7ft 9ins) high. DESCRIPTION TO BE READ IN CONJUNCTION WITH ‘IMPORTANT NOTES REGARDING THE CATALOGUING OF CLOCKS’ printed in the sale catalogue or available from the auctioneers on request. Henry Hindley was born in Great Harwood, near Blackburn, Lancashire 1699, little is known about his early life, however by the mid 1720’s he was making clocks in Wigan where he repaired the church clock in 1726. Hindley moved with his young family (including his son, Joseph born 1728) to the prosperous city of York where, after making clocks for the Mansion House and Guildhall, he gained his Freedom of the city in 1732. Hindley’s talents were such that he equipped his workshop with tools of his own design including an important dividing and wheel cutting engine, a screw cutting lathe and a fusee engine. As well as domestic clocks Hindley received commissions for several turret clocks including York Minster and supplied a range of scientific instruments including two important equatorial telescopes for the Duke of Norfolk and William Constable. By the 1760’s Hindley’s health had deteriorated to the extent that an ever increasing proportion of the business was handled by his son Joseph. Henry died in 1771 with his son and successor Joseph unfortunately dying just three years later in 1774, before he had had the opportunity to stamp his own mark on the family firm. Hindley’s work demonstrates a highly inventive exacting approach with each clock perhaps varying in some way to its predecessor ensuring constant refinement in design and layout. The quality of the finish of his work is generally exceptional being comparable to the best London makers of the period which is why many collector’s refer to Hindley as ‘the Tompion of the North’. The movement of the current lot is a fine example of Hindley’s work exhibiting inventive details such as the cranked pumping mechanism for the calendar dial, gravity fed rack striking, concealed clicks to the barrels and combined hammer spring and stop. The wheelwork is perhaps a little unusual having six-spoke crossings throughout with finely turned collets. The large bob pendulum with lozenge shaped slot for the slider is also noteworthy.

A rare and important George III oak nocturary, 10cm silvered dial inscribed Whitehurst, Derby, edge pins with trip to top, recording pull, un-numbered 30-hour movement, the rectangular case quite plain, plinth base, 197cm high, c.1807 Provenance: Supplied to the Sikes family at The Chauntry, Newark in 1807 John Whitehurst II (1766-1834) pioneered the watch clock or noctuary, prompted by William Strutt FRS, who, as the scientific eleve of Erasmus Darwin FRS, had developed the concept, apparently from an idea that had originated with the maker`s celebrated uncle, John Whitehurst, FRS (1713-1788) who had established the firm in Derby in 1736/37. The earliest recorded examples were supplied to the elder Whitehurst`s friend Josiah Wedgwood (now in the Wedgwood Museum at Barlaston, Staffordshire) and to Henry Cecil, 10th Earl of Exeter (soon to be created Marquess of Exeter) at Burleigh (where it remains) in 1801. These instruments had their pegs (depressed when the recording lever was operated by the watchman, and later re-set by the supervisor) on the edge of the dial and small dials. By about 1810, the dials had been enlarged and a further refinement in which the pegs were set on the face of the dial was evolved in the next decade, the design remaining current until the firm ceased to exist in 1855/1862. All of the clocks by the firm were, from 1809 when John Whitehurst III joined his father in the business, signed Whitehurst & Son/Derby and numbered (from 001). The present example therefore can be dated from the period 1801-1809, and is therefore very early. William Strutt positioned 19 of these clocks around Derby to regulate the patrols of the watch, thus being able to reduce their numbers by more than 50%, gaining thereby the commendation of the Municipal Corporations Act Commissioners in 1834. Literature: Sylvester, C., Domestic Economy (London 1819) 4-6 & n. (the first published description of these instruments) & Craven, M., John Whitehurst of Derby, Clockmaker and Scientist (Mayfield, Staffs., 1996) 203-209, plates IX/71-72 & IX/77.

It encompasses all the major fields of mathematics with special attention paid to Geometry including Astronomical Geometry. The work would have passed through the rigorous censorship of Christopher Grienberg of the Collegio Romano where Aristotelian teachings were adhered to. He had succeeded Christopher Cluvius who had been the prime mover in establishing mathematics in the curriculum of the college and had greatly influenced future Jesuit mathematical writings. It is not known how much of the work can be accredited to Grienberg but it is clear that the mechanical and measuring devices illustrating the work must be by him. Indeed Bettini acknowledges the debt to him in the Scholion Parergicon in the present work.Provenance. The Macclesfield copy (Sotheby`s 10th June 2004 lot 347)

Provenance: The estate of a deceased collector. Purchased Christies SCIENTIFIC INSTRUMENTS South Kensington, 04/12/2004 lot 153. Peter Dollond was born 1730 and died 1820. He was the son of John Dollond, a Huguenot silk weaver, and started business as an optician at the age of twenty in 1750. He was joined by his father in 1752 until the latter`s death in 1761 and then by his brother, John, until his death in 1804. The family business was continued by Peter Dollond`s nephew, George Huggins, who subsequently changed his surname to Dollond. Peter Dollond was appointed optician to George III and the Duke of York and the workshop was renowned for producing high quality instruments. The design of the current lot was conceived by Edward Nairne around 1765 to improve the portability and of the Cuff pattern microscope. The hinged base joint also allows positioning of the instrument to maximise reflected light and makes the instrument much easier to handle.

Wilson Lowry 1762-1824- "Solitude"; published Jan 1st 1786 by John Boydell, Cheapside London, engraving after Gaspar Pousin (Gaspard Dughet) 1615-1675, 56x73cm: together with one further engraving from the same or similar suite after Gaspar Pousin, engraved by John Browne 1741-1801, entitled "Cascade"; published Jan 2st 1786 by John Boydell, Cheapside London, 56x73cm, ea., (2) (unframed) Note: Wilson Lowry trained at the Royal Academy and worked for a number of engravers, as well as Boydell. Lowry developed a number of special instruments to assist his work: about 1790 he devised a ruling machine; in 1801 a device for generating elliptical curves; in 1806 another for making perspective drawings. Lowry was the first engraver to use diamond points and to discover the composition of a corrosive fluid for biting the lines into steel plates. Lowry specialised in making engraving of architectural and mechanical topics, and excelled in perspective views of machinery.

Rare and unusual George I clock by Richard Glynne, London, circa 1720-1725, a fruitwood cased table clock (probably previously ebonised), surmounted by a revolving celestial globe showing phases of the moon on brass S supports with a flower and foliage engraved front bracket above the inverted bell top. The brass 7.5" dial has a very rare trefoil shaped chapter ring (see below) with Roman numerals, and the spandrels are engraved with figures emblematic of the seasons. The centre of the dial has a matt finish. The arch has a subsidiary dial with twin rings one showing minutes and the other lunar dates for the phases of the moon with Arabic numerals (hands missing). On brass ball feet. There are glazed sides and doors enclosing the eight day single train fusee movement. The brass back plate is engraved with scrolling foliage and "Richard Glynne Londini fecit", 25.25" high There are several unusual features in this clock 1 The case is surmounted by a revolving moon phase globe driven by a vertical pillar and a series of cogs from the movement. Knowing the correct moon phase was important because trips on horseback or by coach were much less safe on a dark night and crops could be harvested by the light of the moon. This however is an unusual way of depicting phases of the moon. 2 The trefoil shaped chapter ring is extremely rare although there are a few examples by Glynne`s contemporary Richard Street (See below) On 28th May 1982 Sothebys sold a wall clock by Richard Street of Shoe Lane just off Fleet Street. (Lot five in the sale described as a "sale of nine English clocks"). The clock had previously been sold by them in 1953. The similarities of the two dials are striking not only because of the shape of the chapter ring which was described as pear shaped but because of the style of the engraving of the foliage and numerals and the matt finish to the centre of the dial. Street and Glynne worked close to one another; Street is recorded in Fleet Street until he is thought to have died in 1722 and Glynne was in Fleet Street from 1718-1729 when he retired. 3 The single hour hand mechanism. The shape of the chapter ring means that there must be special arrangements for the single hour hand the shape of which again very closely resembles the hand in the Street clock. The whole of the inner dial revolves and the hand is fixed but has to follow the contours of the inner border of the chapter ring. This is achieved by a spring loading which seems to be the same in both clocks. Street was a distinguished but little known clockmaker whereas Glynne although also described as a clockmaker was much better known for his finely engraved scientific instruments. It is reasonable to suggest that the eccentric dial may well have provided by Street although it is conversely equally possible that the dials were made by Glynne and used by Street in his clocks! There may also have been a contribution from Glynne`s business partner in the 1720s Anne Lea, whose father and mother Philli and Anne Lea were noted ma and globe sellers.(See below) HISTORICAL NOTES RICHARD GLYNNE Richard Glynne (1681-1755), was apprenticed to Henry Wynne in 1696 in the Clockmakers` Company of which he became a freeman in 1705: he became Steward of the Company in 1725. He worked first at the sign of the Atlas and Hercules (1712-16) in Cheapside and subsequently (1718-29) opposite Salisbury Court in Fleet Street, London. On obtaining his freedom in 1705, he married Anne Lea, the daughter of the noted ma and globe-sellers Phili and Anne Lea (see below). From at least 1712 he was working in association if not in formal partnership, with his mother-in-law, advertising a new pair of globes in 1712, and publishing and marketing maps. In parallel with this activity, he made and sold `all sorts of Mathematical instruments, either for Land or Sea, according to the newest improvements` as he stated in an advertisement in 1726. There is another reference to advertising `all Kinds of Dials, Spheres and Globes of all Sizes.` A variety of scientific instruments by Glynne are indeed known. All are of high quality, with clean, well executed engraving uncluttered by unnecessary decoration. Glynne`s fine instruments recommended themselves to a fashionable clientèle, and he was sufficiently successful to be able to retire at the relatively early age of 49 in 1729, his stock being auctioned at the sho of the optician Edward Scarlett in 1730. There is an impressive armillary orrery in the Science Museum in Oxford, dating from around 1720 and standing just over a metre in height. The Museum state on their website that it must have been at the to of his range: an impressive and expensive purchase by one of his most wealthy customers. RICHARD STREET Richard Street was apprenticed to Thomas Tompion; he became a freeman of the Clockmakers Company in 1687 and was elected Junior Warden in 1713. He worked in Shoe Lane just off Fleet Street and there is evidence that he was responsible for some of Tompion`s repeating watch movements. He was undoubtedly well connected and probably his most famous commission is the important Degree Clock which is now at the Old Observatory at Greenwich. This may have been "The black clock on the back stairs" described in Sir Isaac Newton`s personal papers after his death. Sir Isaac had also commissioned from Street a fine and highly unusual clock as a gift for Doctor Bentley who was Master of Trinity College Cambridge in 1708, it apparently had an eccentric chapter ring and an expanding and contracting hand. There is no record of him after 1722 when it is presumed he died.. The dial of the wall clock sold by Sothebys and mentioned above has striking similarities to the dial of this clock by Richard Glynne ANNE LEA Anne Lea was mother in law of Richard Glynne and inherited from her husband Philli who died in 1700. He had been apprenticed to Robert Morden in 1675 and by 1683 was in business as a globe maker with Robert Morden and William Berry. He was one of the leading English map-makers and publishers of his day and described himself as a globe maker in advertisements and in a catalogue of "Globes, spheres, maps, mathematical projections, books, and instruments" in the 1790s. On his death he left a third of all his maps, plates and globes to his wife with the remainder to his children. She also inherited one third of his globe plates. Their daughter, also Anne, married Richard Glynne. Mother and daughter therefore would have inherited a large part of Philli Lea`s stock in trade, which would have been available to Richard Glynne. CONDITION Multiple images of this clock are available. Buyers will be able to assess the condition from these images. The following comments may be of further assistance. There is a screw thread at the to of the globe and obviously a finial is missing from here The glass on the globe is badly cracked The hands from the subsidiary dial are lost. We have removed the globe and to plate and have found no other screw holes in the case indicating that the globe is an original feature and was not added later in place of a handle. Several cogs in the mechanism for driving the globe are replacements The escapement and pendulum are replacements for an original verge escapement. The two large brass brackets holding the clock in the case are not original. There is a hole drilled in the base of the case where it is assumed that some support for the movement was housed but is no longer there. The brass feet are thought to be replacements PROVENANCE This clock is has been sent in for sale by executors from an estate in Winchester. Family tradition indicates that this clock was inherited through the Bohn family of Hull and through earlier connections from the Boleyns.
