AN ENGRAVED BRASS ASTROLABE PROPERTY FROM AN IMPORTANT EUROPEAN PRIVATE COLLECTION Safavid Iran, dated 1125 AH (1713 AD), signed by the maker Amin Mohammad Shams al-DinOf typical circular shape, comprising five engraved plates and an openwork rete with scrolling, intertwined vegetal interlace and an ecliptic ring at the top, the rule and mater densely engraved with Arabic letters and references, the womb featuring six decreasing concentric circles with Arabic inscriptions, the central roundel marked with the date '1125' (1713 AD) and signed by the maker Amin Mohammad Shams al-Din, another six bands occupying half hemisphere on the reverse, the cusp once fitted with a qibla pointer, now missing, engraved with rosettes on the front and an arabesque composition with a lotus flower flanked by split palmette scrolls on the back, with an old Sotheby's London tag reading Ottoman engraved brass astrolabe, Turkey, and extra notes in pen.13cm diameter and 16.5cm long Provenance: Chiswick Auctions, 29 April 2022, lot 92. Used in astronomical observations and for timekeeping, astrolabes allowed users to chart celestial bodies; determine the direction of Mecca; and navigate. Astrolabe makers were highly skilled craftsmen who often worked closely with scholars and astronomers to achieve the greatest level of precision and detail in their creations. Often, these scientific instruments were engraved not only with celestial markers but also religious inscriptions, demonstrating the dual role these devices played in both practical astronomical navigation and religious observance (e.g. determining prayer times and the direction of Mecca). During the Safavid period, their purpose became even more multi-faceted. In fact, despite their functional purpose, astrolabes and scientific tools became symbols of the cultural advancement promoted by the Persian shahs. As an example of this, the renowned Safavid astrolabe made by Muhammad Muqim al-Yazdi in 1647 - 48 AD, created for the Safavid ruler Shah Abbas Il, acts as both an utilitarian instrument, as well as a work of art and reminder of the degree of excellency strived for at the Safavid court. 13cm diameter and 16.5cm long Qty: 10

AN ISLAMIC WOODEN ASTROLABE QUADRANT Possibly North Africa or al-Andalus, Southern Spain, dated 1289AH (1872 - 73AD)Of typical shape with a curved edge and two square sides, made of wood, engraved on one side with an astrolabic grid and scale, inscribed with Arabic numerals, featuring clear and precise angular divisions, marked at regular intervals from 5° to 65°, at the top next to the scale an inscription in Arabic reading the date 1289AH and an auspicious saying referring to the Hajj (the pilgrimage to Mecca), one of the five pillars of Islam, the grid-less reverse with unmarked concentric circles.16.5cm x 17cm This wooden quadrant, dated to 1289AH (approximately 1872-1873AD), is an excellent example of utilitarian Islamic scientific instruments, likely originating from the MENA region. It is made of wood, possibly cedar or olive, both prevalent in North Africa and the southern regions of Spain and traditionally used for items that required durability and detailed carving. The quadrant was traditionally used in astronomy and navigation to measure the angles of celestial bodies and calculate time, a key instrument for Islamic scholars and navigators. The markings on the present example suggest its use for specific astronomical calculations, particularly for determining altitude and direction in relation to the horizon. 16.5cm x 17cm Qty: 1

A Good Swift "Dick" Petrological Microscope English, c.1895, signed to foot ‘J Swift & Son, London’, standing on cast brass foot finished in black lacquer, trunnions at top support body, plano-concave mirror on gimbal below substage, substage assembly with rotating Nicol prism on rotating divided circle for angular measurement, square stage with Swift 2″ patent stage, main body to rear of stage incorporating the ‘Dick’ rotating mechanism with fine focus via screw and course focusing via diagonal rack work, body tube incorporating a sliding plate with aperture and slide in/out Bertrand lens, to top a rotating and folding analyser engraved with 45 degree positions, complete with 2 Swift objectives, 3 eyepieces in original mahogany case The Dick Petrographic Microscope by James Swift & Son: A Historical and Operational Overview Historical Context - The history of the "Dick" Petrographic Microscope is closely intertwined with the evolution of microscopy and mineralogical studies in the late 19th and early 20th centuries. This particular microscope was developed by James Swift & Son, a company that became a key player in the production of scientific instruments in England during that period. James Powell Swift initially worked under the instrument maker Andrew Ross before establishing his own company in 1854. As the company expanded and his son joined in 1877, it was renamed J. Swift & Son. By 1912, the firm had evolved into James Swift & Son Ltd. One of the significant advancements in the field of petrographic microscopy came from Allen B. Dick, an inventor who, in 1889, designed a unique gearing system that allowed for synchronized rotation of both the polarizer (beneath the stage) and the analyzer (above the stage). This innovation made it easier to observe and study mineral samples by eliminating the need for constant adjustment and re-centration of the specimen and objective lenses when rotating the stage. Swift and Son were the first to manufacture microscopes incorporating Dick's patented gearing system, and they introduced the first model in their 1891 catalog. Known as the "Dick Microscope," . Although it was expensive and relatively few examples remain today, it was used by prominent geologists and mineralogists, including during the British polar expeditions to Antarctica. In particular, photos from the expeditions show geologist Frank Debenham preparing samples using a Swift/Dick microscope, highlighting the instrument’s role in significant scientific research. Over the years, the Dick Microscope underwent several iterations, with various modifications made to improve its design and functionality. Although these microscopes were produced for many years, they were always considered premium instruments, and as a result, their numbers were limited. Today, surviving examples of the Dick Microscope are rare, and many are missing essential components such as the slotted eyepiece or waveplates. The Operation of the Dick Microscope The Dick Petrographic Microscope was designed for examining thin sections of minerals using polarized light, a key technique in petrographic analysis. The microscope’s construction allows for the observation of mineralogical structures in ways that are not possible with conventional optical microscopes. Key to its functionality is the polarizer, which sits beneath the stage, and the analyzer, positioned above the stage. These two components are crucial for creating "crossed polars," a method that significantly enhances the visibility of mineral structures by utilizing polarized light. Here’s how it works: 1. Polarized Light: When light passes through the polarizer, only waves vibrating in one direction are allowed through. When no sample is on the stage and the analyzer is aligned at 90 degrees to the polarizer, the field of view appears black—a condition known as "extinction." 2. Anisotropic Materials: When a mineral sample, specifically an anisotropic material (one that has different properties depending on direction), is placed on the stage, it alters the path of the polarized light. Instead of the black field seen during extinction, various colors or interference patterns appear, depending on the mineral’s optical properties and its orientation relative to the light. 3. Crossed Polars and Rotation: The Dick Microscope’s main innovation is the synchronized gearing mechanism that allows both the polarizer and analyzer to rotate together. This eliminates the need to manually rotate the stage and re-center the objective lens—a process that could be tedious and required great precision. With the polarizer and analyzer moving in unison, the specimen remains stationary, allowing for smooth and efficient analysis of even the smallest mineral grains. 4. Mineral Identification: By observing the way light interacts with the mineral as the polarizer and analyzer rotate, geologists can identify minerals based on their optical properties, such as birefringence, pleochroism, and extinction angles. This technique is especially useful for studying thin sections of rocks, where the optical properties of individual mineral grains provide clues to their composition and formation history. 5. Waveplates and Additional Features: Many petrographic microscopes, including the Dick model, were equipped with accessories like waveplates, which help to determine additional optical properties of minerals, such as their optical sign (positive or negative). However, many surviving examples of the Dick Microscope lack these additional features, possibly due to wear or loss over time. Significance in Geological Research - The Dick Microscope represents an importatn step in petrographic microscopy. By simplifying the process of rotating polarizers and analyzers, it facilitated the study of mineral structures, making it easier for geologists to carry out precise optical analysis. This design innovation became particularly valuable in the field of geology, where the accurate identification and analysis of minerals are essential for understanding rock formation and the Earth's history. The instrument's role in early 20th-century geological expeditions, such as those to Antarctica, underscores its importance in scientific discovery. The high precision and quality of the microscope made it a valuabel tool for researchers working in some of the most challenging environments on Earth.

An Irish Spectroscope, Yeates Dublin, Irish, c.1880, engraved along on of the arms 'YEATES & SON DUBLIN', standing on a cast iron base with brass pillar support, prism housing in the center under a cover, with fixed collimator telescope, viewing telescope on a micrometer scale for angular adjustment, 27cm tall. Yeates & Son, Dublin - Stephen Mitchell Yeates, born in 1832, was the son of George Mitchell Yeates, an instrument maker in Dublin. Upon his father’s death in 1865, Stephen took over the family business, which had been established as "Instrument Makers and Opticians" in 1790. The shop, originally located at another site, was moved to 2 Grafton Street in 1827, strategically positioned across from Trinity College. This location proved to be advantageous, as the close proximity to the university facilitated a steady stream of business, particularly in the sale and manufacture of scientific instruments used in academia. In 1865, the business was officially renamed Yeates & Son. The company advertised itself as "Instrument Makers to the University," underscoring its relationship with Trinity College. This connection was pivotal, as many of the instruments built by Yeates & Son were utilized by the college for various scientific purposes. Stephen Mitchell Yeates managed the business until his death in 1901. The firm remained a prominent supplier of scientific instruments in Dublin throughout the 19th century. Many of the instruments by Yeates & Son are still housed at Trinity College,

An Early First Form, Wollaston Pattern Crystallographic Goniometer, Thomas Jones, English, c.1810, engraved to the front 'Thomas Jones, 62 Charring Cross' the goniometer on a turned French polished wooden base with supporting 'A' frame terminating in a split bearing, with 2 knurled wheels at the rear, 1 to turn the spindal holding the armature the other to turn the spindal and the scale, with a silvered vernier scale at the side reading to arc-minutes, this is the first form of Wollaston goniometer with the the sprung stop at the 0 and 180 positions which was a feature dispensed with on later devices, in the original Mahogany case with catches, case height 15cm, with period glass dome cover Jones, Thomas, according to Clifton Jones was working at 62 Charing cross from 1816, was apprentice to Jesse Ramsden History and Operation of the Wollaston Crystallographic Goniometer The Wollaston crystallographic goniometer was a significant development in the field of crystallography, enabling scientists to measure the angles between crystal faces with great precision. The invention of this device is attributed to William Hyde Wollaston, a British scientist and polymath, in the early 19th century. His work not only advanced the study of crystallography but also laid the foundation for future innovations in mineralogy and materials science. Before the development of the goniometer, scientists faced challenges in accurately measuring the geometry of crystals. Crystals, with their symmetrical and structured shapes, had long intrigued scientists and mathematicians alike. However, understanding their internal symmetry required precise measurements, particularly of the angles between their faces. Traditional tools used for such measurements, were inadequate for obtaining the level of accuracy needed for detailed scientific study. In 1809, Wollaston introduced his crystallographic goniometer. This instrument allowed for highly precise angular measurements of crystal faces, down to fractions of a degree. Considered the first reflecting goniometer, a type of instrument that relies on measuring the reflection of light to determine the angle between crystal faces, as opposed to contact goniometers, which require physical interaction with the crystal. Wollaston’s invention significantly impacted mineralogy and crystallography because it allowed for the accurate measurement of the fundamental angles of crystals, leading to better classification and understanding of crystal structures. By measuring the angles between different faces, researchers could deduce the symmetry and internal structure of the crystal. This was particularly useful for the study of minerals, as crystals often form naturally in these materials. Operation of the Wollaston Goniometer The Wollaston goniometer is classified as a reflecting goniometer, where the measurement of angles is based on the reflection of light. The basic principle involves aligning the reflection of a light source on one face of the crystal, followed by measuring the angle at which the light reflects from another face. The operation of the Wollaston goniometer can be broken down into a few key steps: 1: Mounting the Crystal: The crystal specimen is carefully mounted on a spindle that can rotate using a small piece of wax. The crystal is positioned so that one of its faces can reflect light. Precise mounting is critical, as the measurement accuracy depends on the crystal's stability and the reflected light's clarity. Aligning the Light Source: A light source is directed at the mounted crystal. In Wollaston’s design, this was often natural light or a simple lamp. The goal is to ensure that the light strikes one of the crystal's faces at a specific angle and reflects back toward an observer. Measuring the Reflected Angle: The observer views the reflection of the light from one face of the crystal. The goniometer is equipped with a graduated circle that can rotate along with the crystal. Once the reflection is observed, the goniometer is rotated until the light reflects from another face of the crystal. The angle of rotation is measured using the graduated circle. This angle corresponds to the interfacial angle between the two crystal faces. Repeating for Different Faces: The process is repeated for different pairs of faces to fully characterize the crystal. By systematically measuring the angles between different faces, it is possible to derive the symmetry and geometry of the crystal. The precision of the Wollaston goniometer allowed for measurements to within 30 seconds of arc, which was a major improvement over previous instruments. The reflecting goniometer, unlike contact goniometers, did not require any physical contact with the crystal, which could damage fragile specimens. Furthermore, by using the reflection of light, it was possible to obtain much more accurate measurements, as light reflection is a highly precise phenomenon that can be accurately measured. Impact on Crystallography - The Wollaston goniometer became an essential tool in crystallography, enabling researchers to explore the geometrical properties of crystals with a great level of detail. Its use led to the discovery of several important principles in crystallography, including the identification of crystal symmetries and the formulation of laws such as the law of constant interfacial angles, which states that the angles between equivalent faces of crystals of the same substance are constant. Wollaston’s contribution also paved the way for the development of more advanced goniometers and crystallographic tools. Later innovations included more precise optical systems and automated goniometers, which could be used to measure crystals with even greater accuracy and efficiency. In modern crystallography, the basic principles of angle measurement established by the Wollaston goniometer remain relevant, even as X-ray diffraction and other techniques have expanded the toolkit available to researchers.

Brass Leeuwenhoek-type Simple Microscope, in the manner of the microscopes built by  Maitland/Artis in the 19th century, the lens-plates 47.07mm x 27.6mm x 1.56mm with 3 rivets and hammer marks around lens aperture, with spherical lens, the long-screw adjuster with flattened handle, the shaped bridge-piece with vertical adjustment screw and focusing screw, with angle bracket and securing screw, good uniform patination, in a card case marked 'PERSONAL PROPERTY OF B. BRACEGIRDLE'Antonie van Leeuwenhoek (1632–1723), was a Dutch scientist and tradesman widely regarded as the "father of microbiology." His groundbreaking work with microscopes enabled him to explore a previously invisible world, revolutionizing the fields of biology and microbiology. Van Leeuwenhoek's life and scientific contributions were marked by curiosity, keen observational skills, and a commitment to scientific inquiry that led to some of the most significant discoveries in natural history. Born in Delft, Netherlands, Van Leeuwenhoek initially pursued a career in textile commerce. He worked as a draper, a profession that involved the inspection of cloth quality. His interest in lenses and magnification arose from his need to observe the threads of textiles more closely, a practice common in the industry. Van Leeuwenhoek’s advancements in microscopy were not the result of formal scientific training but rather the outcome of self-taught experimentation and dedication. While simple magnifying glasses had been in use for centuries, Van Leeuwenhoek’s microscopes were far more advanced. He did not invent the microscope, as early forms had been created by figures like Zacharias Janssen and Galileo Galilei. Instead, Van Leeuwenhoek’s unique contribution lay in his ability to improve the quality of lenses, enabling far greater magnification. Using small lenses, Van Leeuwenhoek built simple single-lens microscopes that could magnify objects up to 275 times, an unprecedented level at the time. His methods produced lenses of superior quality, allowing him to observe objects in finer detail than any other scientist of his era. Through his microscopic investigations, Van Leeuwenhoek became the first person to document and describe the existence of microorganisms, which he referred to as "animalcules." His observations included bacteria, protists, sperm cells, and red blood cells. In 1674, he reported his discovery of single-celled organisms living in water, and in subsequent years, he provided detailed descriptions of various forms of life, such as protozoa and algae. Van Leeuwenhoek’s observations of bacteria in dental plaque and other substances were particularly groundbreaking. His detailed descriptions of the minute organisms helped establish the foundation for microbiology. He meticulously recorded his findings in correspondence with the Royal Society of London, where his work was met with both skepticism and admiration. The impact of Van Leeuwenhoek’s work cannot be overstated. His discoveries transformed scientific understanding of life at a microscopic level and challenged prevailing notions of biology. Until his work, the existence of a microbial world was entirely unknown. His findings laid the groundwork for future scientists, such as Louis Pasteur and Robert Koch, whose work on germ theory and microbiology expanded upon Van Leeuwenhoek’s early observations. Although Van Leeuwenhoek did not publish formal scientific papers, he communicated his findings extensively through letters to the Royal Society, which translated and published them in *Philosophical Transactions*. His documentation and sketches of microorganisms were essential for validating his discoveries and spreading his influence across Europe. Additionally, his improvements to lens-making influenced the design of microscopes in subsequent centuries, establishing standards that would be refined in later technological advancements. Van Leeuwenhoek's contributions to science were widely recognized during his lifetime, and he continued his work well into old age. He was visited by notable figures such as Peter the Great of Russia, who was intrigued by his research. Despite his lack of formal education, Van Leeuwenhoek was elected a Fellow of the Royal Society in 1680. Brian Bracegirdle (1933–2019) was a well known figure in the fields of microscopy and the history of scientific instruments. His career began in the study of biology, where he earned a PhD in fungal spore dispersal from the University of London. However, his interests soon expanded into the history and development of microscopy, leading him to become a leading expert in the field. Bracegirdle had a long-standing association with the Science Museum in London, where he made significant contributions to its collections of historic microscopes. One of his key achievements was his work on cataloging and documenting historical microscopes, which helped preserve the legacy of this important scientific tool. His deep knowledge and passion for the subject were shared with a wider audience through his extensive writing. Bracegirdle was also a popular lecturer, and his engaging teaching style left a lasting impact on students and colleagues alike. Brian Bracegirdle authored numerous books on microscopy and related topics, many of which became essential reading for historians and scientists. His publications include A History of Microtechnique* (1978) Microscopes: A Short History* (1978) Beads of Glass: Leeuwenhoek and the Early Microscope (1983) Microscopical Mounts and Mounters* (1995), The Quekett Microscopical Club 1865–2015* (2016), and several volumes in the *An Atlas of Microscopy* series. These works have cemented his legacy as an authority in the history of scientific instruments. His contributions remain vital to our understanding of the development of microscopy and its role in advancing scientific knowledge.

A FINE GEORGE II POCKET WATCH MOVEMENT WITH CYLINDER ESCAPEMENTGEORGE GRAHAM, LONDON, NUMBER 6077, CIRCA 1742The gilt full plate single fusee movement with four square baluster pillars pinned through the backplate, scroll-pierced stop-iron block and cylinder escapement regulated by sprung three-arm steel balance with Tompion type regulation, the backplate with fine symmetric foliate scroll pierced and engraved balance cock with faceted diamond endstone, herringbone bordered canted rim and with wedge-shaped scroll engraved foot flanked by silvered regulation disc set within adjacent applied scroll engraved panel infill opposing signature Geo. Graham, London and numbered 6077, with gilt brass dust cover similarly signed Geo. Graham, London.The pillar plate 3.5cm (1.375ins) diameter. Provenance:The Leonard Fuller Collection. Purchased from Gerald E. Marsh, Winchester, 11th December 2004 as part of a package deal comprising the oval pre-haispring watch by Vallier and two other watch movements by John Knibb and Thomas Tompion for a total of £14,000. George Graham was born in around 1673 in Kirklinton, Cumberland, but by 1688 he had moved to London and entered into an apprenticeship with Henry Aske. Graham gained his freedom of the Clockmakers' Company in 1695 and went to work for Thomas Tompion, whose niece, Elizabeth, he married at St. Mary le Bow in September 1704. After the Tompion's failed partnership with Edard Banger Graham was trusted to become his successor with the two makers entering into a formal a partnership in 1711. On Tompion's death in 1713 George Graham inherited the business 'on the corner of Water Lane in Fleet Street' and continued there until 1720 when he relocated to 'the Dial and One Crown' further up Fleet Street, nearer Fleet Bridge.George Graham maintained the same exacting standards as his former master and also continued the serial numbering system established in around 1680/81. In 1722 he served as Master of the Clockmakers' Company and went on to establish himself as one of the most important clockmakers of his generation. Amongst his achievements was the further development of the deadbeat escapement, invention of the mercury compensated pendulum and the cylinder watch escapement. As well as clocks and watches George Graham was also a highly accomplished maker of scientific instruments with perhaps his most famous creation being the planetarium made for Charles Boyle, Earl of Orrery. He also produced the great mural quadrant for Edmund Halley at Greenwich observatory, also a fine transit instrument and the zenith sector used by James Bradley in his discoveries. Through his observations in testing his very highly regarded compasses Graham also discovered the diurnal variation in the terrestrial magnetic field in 1722/23.George Graham also became an ardent supporter of John Harrison in the development of his marine chronometers to the extent that he forwarded an interest free private loan of £200 to Harrison to facilitate the building of H1. George Graham died in 1751 and was buried next to his former master in Westminster Abbey, leaving the business in the hands of a former apprentices, Samuel Barclay and Thomas Colley. George Graham's legacy is perhaps best reflected by the subsequent work of another former apprentice, Thomas Mudge, who went on to continue in the development of the marine chronometer after Harrison, and to invent the lever watch escapement. The cylinder escapement was developed in around 1695 by Thomas Tompion and further refined by George Graham in 1726. This new escapement was perhaps the first developed exclusively for watch work and, as well as being a better rate keeper, the cylinder escapement also allowed movements to be made more compact (due to the escapement operating in one plane only). However, being a form of frictional rest escapement, the cylinder escapement was prone to relatively heavy rates of wear hence was less reliable than the verge (until hardened steel escape wheels and ruby cylinders were developed later in the 18th century). George Graham's faith in this new design of escapement was such that he incorporated it into all of his watches from around 1725/6 (between serial numbers 5175 and 5182). Condition Report: The movement is complete and in working condition. The train appears all-original with the probable exception of the escape wheel which is probably a 'service replacement'. Some of the steelwork (most notably the minute hand post and winding squares) is oxidised and the silvered regulation disc is discoloured. The backcock securing screw is a little chewed. The movement retains gilt finish to wheelwork (except escape wheel) and to the plates with minimal wear/scratching. The dust cover is missing its steel slide latch and is generally discoloured/oxidised but would no doubt clean very well. The dial mounting plate is present but with solder residue from a previous alternative mounting (although there appears to be no additional modifications/holes etc). The hour wheel/tube is present. Movement has a winding key. Condition Report Disclaimer

Purchased from Malcolm Gardner, Sevenoaks, 29th August 1967 for £265. George Graham was born in around 1673 in Kirklinton, Cumberland, but by 1688 he had moved to London and entered into an apprenticeship with Henry Aske. Graham gained his freedom of the Clockmakers' Company in 1695 and went to work for Thomas Tompion, whose niece, Elizabeth, he married at St. Mary le Bow in September 1704. After the Tompion's failed partnership with Edard Banger Graham was trusted to become his successor with the two makers entering into a formal a partnership in 1711. On Tompion's death in 1713 George Graham inherited the business 'on the corner of Water Lane in Fleet Street' and continued there until 1720 when he relocated to 'the Dial and One Crown' further up Fleet Street, nearer Fleet Bridge.George Graham maintained the same exacting standards as his former master and also continued the serial numbering system established in around 1680/81. In 1722 he served as Master of the Clockmakers' Company and went on to establish himself as one of the most important clockmakers of his generation. Amongst his achievements was the further development of the deadbeat escapement, invention of the mercury compensated pendulum and the cylinder watch escapement. As well as clocks and watches George Graham was also a highly accomplished maker of scientific instruments with perhaps his most famous creation being the planetarium made for Charles Boyle, Earl of Orrery. He also produced the great mural quadrant for Edmund Halley at Greenwich observatory, also a fine transit instrument and the zenith sector used by James Bradley in his discoveries. Through his observations in testing his very highly regarded compasses Graham also discovered the diurnal variation in the terrestrial magnetic field in 1722/23.George Graham also became an ardent supporter of John Harrison in the development of his marine chronometers to the extent that he forwarded an interest free private loan of £200 to Harrison to facilitate the building of H1. George Graham died in 1751 and was buried next to his former master in Westminster Abbey, leaving the business in the hands of a former apprentices, Samuel Barclay and Thomas Colley. George Graham's legacy is perhaps best reflected by the subsequent work of another former apprentice, Thomas Mudge, who went on to continue in the development of the marine chronometer after Harrison, and to invent the lever watch escapement. The cylinder escapement was developed in around 1695 by Thomas Tompion and further refined by George Graham in 1726. This new escapement was perhaps the first developed exclusively for watch work and, as well as being a better rate keeper, the cylinder escapement also allowed movements to be made more compact (due to the escapement operating in one plane only). However, being a form of frictional rest escapement, the cylinder escapement was prone to relatively heavy rates of wear hence was less reliable than the verge (until hardened steel escape wheels and ruby cylinders were developed later in the 18th century). George Graham's faith in this new design of escapement was such that he incorporated it into all of his watches from around 1725/6 (between serial numbers 5175 and 5182). The present lot is a fine relatively early example of a Graham cylinder watch in fine condition complete with finely worked heavy outer repousse case. Condition Report: The watch is in fine clean working condition with no visible evidence of alteration or noticeable replacements however it is possible that the escapewheel and cylinder may be 'service' replacements. The mechanism retains its gilt finish with minimal wear and with other faults limited to a couple of small scratches to the backplate. The dust cover is in fine condition. The dial appears to be in perfect condition including the hands which are vey finely made. The inner case is in fine original condition with minimal wear and no discernible denting. The outer case has some slight wear to the high spots to the rear cover otherwise in in fine original condition.Gross weight 133g. Watch has a winding key. Condition Report Disclaimer

A VICTORIAN CAST IRON AND BRASS HOUR-STRIKING TURRET CLOCK MOVEMENTW.J. THOMPSON, ASHFORD, CIRCA 1870The decorative pierced break-arch frame incorporating fan-light design to upper section and decorative turned brass bushes to the pivot holes united by four double-screwed columnar pillars and a brass top beam enclosing four-wheel trains with six-spoke wheel crossings, internal rack striking mechanism now sounding on a small bell set above the train, maintaining power, and deadbeat escapement with adjustable pallets and fine beat crutch adjustment for regulation by long pendulum, the front with winding squares, twin vane fly and brass Arabic five-minute setting dial inscribed W.J THOMPSON, ASHFORD, the rear with wide-jaw pendulum suspension bracket, bevel-gear assembly, yoke and short dial take-off work now driving a six inch white enamel Roman numeral dial inscribed G. KENT LTD, LONDON & LUTON to centre set on a post, along with motionwork, to the apex of the frame, with two sets of weights and lines and mounted on a later green painted wood display stand.The frame 51cm (20ins) high; total height (including stand, frame and dial), 204cm (85.75ins approx.) overall. William James Thompson is recorded in Loomes, Brian Clockmakers & Watchmakers of the World, Volume 2, as working in Ashford, Kent in 1874. George Kent Limited were manufacturers of specialist metering equipment who were first established at 199-201, High Holborn, London by George Kent. Initially traded as manufacturers and retailers of domestic equipment but expanded to produce early refrigerators and machinery such as knife sharpeners. In 1907 the business became a limited Company and set-up a factory in Luton the following year adding the manufacturing of specialist metering equipment to their diverse range of operations. During WWI the factory was re-purposed for the war effort and in 1921 the business merged with J. Blakeborough and Sons to form 'George Kent Ltd and J. Blakeborough and Sons Ltd'. The firm subsequently went on to acquire other related businesses (including Cambridge Instrument Co. in 1968) to become the largest British manufacturer of industrial Instruments. George Kent Limited were finally acquired by the Swiss conglomerate, Brown Boveri & Co., in 1974 with their various divisions subsequently re-organised and combined to create a series of leading specialist manufacturers in industrial, scientific and medical instrumentation.

A FINE REGENCY LACQUERED BRASS AND MAHOGANY 'PORTABLE ORRERY' AND TELLURIANWILLIAM JONES, LONDON, CIRCA 1815The tellurian assembly with removable brass sphere representing the sun forming the central fixed axis of an arrangement of gears set between slender shaped plates engraved Monthly Preceptor No. 2 above To Miss Eliz'th Parker, Aged 14, of Mettingham, near Bungay, Suffolk, as the Reward of distinguished merit to the upper surface, terminating with a tiered arrangement of paper scale annotated with the age of the moon including eight images showing progression of the phases beneath central ring showing signed of the Zodiac and upper included ring forming the track of moon which rises and falls as it processes around a central bone terrestrial sphere, the train operated by rotating the assembly clockwise around the central pivot over a 7.75 inch disc base applied with printed paper scale annotated with calendar divided for the months and signs of the Zodiac to circumference, the middle concentric band annotated for the seasons and equinoxes, and the centre illustrated with planets of the solar system drawn to show their relative sizes along with inscription A NEW PORTABLE ORRERY, Invented and Made by W. JONES, and Sold by him in Holborn, LONDON; with original mahogany box containing a small oil can lamp can to allow the solar sphere to be substituted for a light source; together with separately cased orrery or planetarium attachment, with central post applied with brass solar sphere issuing pivoted graduated radial arms applied with bone and ivory spheres depicting Mercury, Venus, Earth, Mars, Jupiter and Saturn together with respective moons.The principal box 12cm (4.75ins) high, 22cm (8.5ins) square; the planetarium box 3.2cm (1.25ins) high, 20cm (8ins) wide, 9.5cm (3.75ins) deep. Provenance:The Leonard Fuller Collection. Purchased from Harriet Wynter Limited Arts and Sciences, London, 26th June 1975. Exhibited at Asprey and Company The Clockwork of the Heavens - An exhibition of astronomical clocks, watches and allied scientific instruments presented by Asprey & Company with the special help of Harriet Wynter and the collaboration of various museums and private collections London, November 1973, exhibit number 74.  William Jones is recorded in Banfield, Edwin BAROMETER MAKERS AND RETAILERS 1660-1900 as apprenticed to the highly regarded maker Benjamin Martin. He went into partnership with his brother, Samuel Jones (apprenticed to George Adams Junior, instrument maker to George II) in 1791. The partnership worked from several addresses in Holborn 1791-1859 (including 135 Holborn 1792-1800 and 30 Holborn 1800-1859) and became one of the most important firms of scientific instrument makers of the late Georgian/Regency period.  The design of present lot was developed by William Jones in 1812 primarily as an education aid based upon the principles of 'James Ferguson's construction'. The Tellurian was intended demonstrate astronomical phenomena such as the reasons for day and night, seasons, and eclipses, related to the diurnal rotation of the earth, the annual revolution of the earth around the sun, and monthly revolution of the moon around the earth. Whilst the 'planetarium' was a much simpler model intended to illustrate the basic construction of the solar system. Condition Report: The instrument is generally in very good original condition. The tellurium assembly is fully operational with the overlaid papers within the mechanism intact with minimal discolouration. There is some discolouration/oxidation to the brass and the ivory terrestrial sphere has a slight shrinkage crack and a couple of other small surface blemishes. The paper applied to the base are free from tears, lifting or heavy scuffs. The colour has browned to a darkish cream tone and one of the pigments used to highlight the annotations has oxidised heavily resulting in localised dark patches within the print. The base panel is free from splits/cracks and is straight. The red pigment bordering the edge has flaking/wear. The planetarium attachment is complete and in good original condition. The brass has overall light oxidation and a couple of the spheres have been re-glued onto their supports. The box containing the planetarium is in fine original condition with faults limited to a few light bumps and scuffs and other minor age-related blemishes. The box for the instrument contains a cylindrical tinned metal oil lamp fitting which is empty does not have a wick fitted, there is also a spare hole suggesting a support some other accessory or is perhaps holding place for brass solar sphere when it is removed from the tellurium. The rear top edge of the box has had a full width slip of wood let-in across the full width probably to repair a section that has split away from the rear edge; there is also a small bruise near the lock suggesting that it has been jemmied-open at some point, otherwise box is in good original with faults limited to minor bumps, scuffs and other age-related blemishes.Box has a key for the lock. Condition Report Disclaimer

Edward Nairne died in 1806 although some instruments signed for 'Nairne and Blunt' are believed to have been made after that time. Thomas Blunt was a distinguished instrument maker who was credited with assisting J.H. Magellan with some of the features of his 'New Barometer' devised in 1779. Blunt is believed to have continued alone from his Cornhill address until his death in 1822; he was succeeded by T. Harris.

John Weiss is recorded by Clifton as working 62 Strand and 287 Oxford Street, London 1831-51. Condition Report: As catalogued the set is 'composed' hence comprises implements by differing makers and of differing patterns; also it is incomplete - see online listing images for vacancies within the box fittings. The steelwork is generally in good condition as it seems that previous owners smeared the implements with petroleum jelly before storing away, however there is some localised oxidation to some of the items. A few of the knives show evidence of past sharpening and a small quantity of the implements have some wear/chipping to the ebony grips. The block positioned to the right-hand edge of the inside of the lid (supporting saw implements) is currently loose (just needs gluing into place). The exterior of the box has historic scuffs and scratches but is generally in sound original condition. There is no lock key present. Condition Report Disclaimer

Original Royal Microscopical Society Recipt, Frank Crisp, 1870, an original recipt for membership of the Royal Microscopical Society, dated April 1870 for Frank Crisp Esq. Sir Frank Crisp, 1st Baronet, distinguished himself not only in the legal arena but also as a active meber in the field of microscopy. Born on October 25, 1843, in London, Crisp's early years were marked by personal tragedy, losing his mother at a tender age. Raised by his grandfather, John Filby Childs, Crisp exhibited a remarkable intellect and an insatiable curiosity about the natural world. His journey into the world of law commenced at the age of 16 when he began his apprenticeship with a solicitor firm while simultaneously pursuing studies at the University of London. His academic prowess earned him a BA in 1864 and LLB in 1865, laying the foundation for his legal career. In 1867, Crisp married Catherine Howes, embarking on a partnership that would see them deeply involved in both legal and scientific pursuits. Crisp's passion for microscopy led him to become an enthusiastic member of the Royal Microscopical Society, where he not only participated actively but also served in various capacities, including as an officer. His generosity towards the society manifested through donations of furniture, books, and instruments, illustrating his commitment to advancing scientific knowledge. Despite his burgeoning legal career, Crisp's fascination with the microscopic world remained undiminished. He delved into the intricacies of microscopy, contributing significantly to the understanding of this field. Crisp's legal expertise garnered him prestigious clients, including foreign railroad companies and the Imperial Japanese Navy. His involvement in drafting the contract for the cutting of the renowned Cullinan diamond underscored his prowess in navigating complex legal agreements. In recognition of his invaluable services to the Liberal Party, Crisp was knighted in 1907 and subsequently elevated to the baronetcy in 1913. These honors reflected not only his legal acumen but also his unwavering commitment to public service. Beyond his legal and scientific pursuits, Crisp was a passionate horticulturist. He acquired Friar Park in Henley-on-Thames in 1889 and transformed it into a botanical marvel, featuring an impressive alpine garden inspired by his love for natural beauty.
