Instrument - Hydrometer, 1878 to 1930s
... Scientific Instrument... and scientific instrument makers Kasner & Moss of 17 Collins Street West... hinges. The scientific instrument shows signs of heavy use... was manufactured by the optical and scientific instrument makers Kasner ...This Sikes brass hydrometer was manufactured by the optical and scientific instrument makers Kasner & Moss of 17 Collins Street West, Melbourne, in the latter part of the nineteenth century. The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. This hydrometer set was donated to Flagstaff Hill in 1979 by local wine and spirits merchants Lynch Bros of Fairy Street, Warrnambool. Giffen Russell had established the business in 1878, and Harry Lynch took it over in the 1930s, and after he passed away in 1953 Kevin Matthew Lynch became proprietor of K M Lynch Food and Liquor. The business closed in the 2010s. The hydrometer may date back to the establishment of the business in 1878, as Kasner & Moss were selling hydrometers in Melbourne from 1864. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid. This hydrometer and its fitted and hinged wooden container show signs of heavy and protracted use in a working environment. Although the instrument has some parts missing and has been recently repaired, the original quality of the inlaid box and the fine engraving on the instrument and the attachable weights, are indications of the hydrometer’s very real value when new. This Sikes hydrometer, bearing the maker's mark of “Kasner & Moss Melbourne” and the registered number “20373”, was presented to the purchasing public as a precision-made instrument designed for professional use. The Sikes hydrometer is of local significance because of its implied association with the alcohol trade in the southwest region of Victoria. It was donated by a family member of Lynch Bros, a local licensed outlet for wines and spirits in the period before the general relaxation of liquor licensing laws in the State of Victoria. It may have belonged to Griffin Russell who established the liquor store in 1878.Hydrometer; original Sikes brass hydrometer in a polished wooden case with an inlaid plaque on the lid. The brass float is a sphere with a thin flat upper stem and a short, lower stem with a bulb-shaped end. The upper stem is engraved scale on both sides with the numbers 1 to 10, and five divisions between each number. There are ten fixed pegs in the base to secure the thick brass horseshoe-shaped, numbered, various-sized weights (20, 30, 40, 80, 90); the free pegs would have originally stored another five weights (10, 50, 60, 70, and 100). The empty compartment in the box suggests another part in the initial set, probably a thermometer. The fitted, fabric-lined box has two brass closures and two brass hinges. The scientific instrument shows signs of heavy use and repairs. The Serial Number on the float matches the Serial Numbers on the weights. The plaque on the lid, the float and the weights have inscriptions. Made by Kasner & Moss, Melbourne. Plaque: “SIKES HYDROMETER / KASNER & MOSS / MELBOURNE” On float's lower stem: “SIKES 20373” On one thin edge of the float's scale, engraved in script “Kasner & Moss” and stamped “MELBOURNE”, and symbol“P” rotated 90 degrees. On the opposite thin edge of the float: “N20.373”, “SIKES”, “I P % II O” (in ornate capitals). Each weight has s unique number, and the same serial number “20373”.flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, sikes hydrometer, scientific instrument, pressure measurement, measuring instrument, ullage tool, customs, excise duty, tax, alcohol content, proof, calibrate, standard weights and measures, tariff, kasner & moss, scientific instrument makers, specific gravity, liquid density, alcohol testing, technology, alcohol measurement, proof spirit, wine and spirits merchants, local business, brass measuring instrument, k m lynch, giffen russell, harry lynch -

Theodolite, Mid 19th Century
... scientific instrument... a scientific instrument making business in London in 1826. Edward... established a scientific instrument making business in London in 1826 ...The theodolite was sold by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments. Thomas Gaunt photograph was included in an album of security identity portraits of members of the Victorian Court, Centennial International Exhibition, Melbourne, 1888. (See further details below.) History for Troughton & Simms: Edward Troughton & William Simms established a scientific instrument making business in London in 1826. Edward Troughton (1756-1835) had previously had his own scientific instrument business, inherited from his father. His achievement's included a transit telescope for Greenwich Observatory (1816) and the precision surveying instruments for the Ordnance Survey of Britain, Ireland and India. William Simms (1793-1860) had trained as a goldsmith and began to gain work dividing circles on fine astronomical instruments. When William Simms died in 1860, the business was taken over by his son James and nephew William. Troughton & Simms shop in Fleet Street became the hub of the finest scientific instrument made in London, in a period in which there was an expanding demand for precision instruments, for astronomy, surveying and precision measurement. They made instruments for Greenwich Observatory, for imperial surveys and exploring expeditions. When fire destroyed the Houses of Parliament in 1834, the firm was commissioned to create new standard lengths, this required 10 years of testing against the remaining old measurements. Troughton and Simms made several of the main instruments for Melbourne Observatory, including an 18 inch azimuth used of the Geodetic Survey, portable transit instrument (circa 1850), zenith sector (1860), a 4.5 inch equatorial telescope (1862), an 8 inch equatorial telescope (1874) spectroscope (1877) and an 8 inch transit instrument in (1884). While the firm had an excellent reputation for quality the company exasperated many of its customers with delays of years in delivering some instruments. History for Thomas Gaunt: Thomas Ambrose Gaunt (1829 – 1890) was a jeweller, clock maker, and manufacturer of scientific instruments, whose head office and showroom were at 337–339 Bourke Street, Melbourne, Victoria, Australia. Thomas Gaunt established Melbourne's leading watchmaking, optical and jewellery business during the second half of the 19th century. Gaunt arrived in Melbourne in 1852, and by 1858 had established his own business at 14 Little Bourke Street. Around 1869 he moved to new premises in Bourke Street on the corner of Royal Arcade, Gaunt's shop quickly became a Melbourne institution. Gaunt proudly advertised that he was 'The only watch manufacturer in the Australian colonies'. While many watches and clocks may have had Gaunt's name on the dial, few would have been made locally. Gaunt did make some watches for exhibitions, and perhaps a few expensive watches for wealthy individuals. Gaunt's received a telegraph signal from Melbourne Observatory each day to correct his main clock and used this signal to rate and repair ship's chronometers and good quality watches. Thomas Gaunt also developed a department that focused on scientific instrumentation, making thermometers and barometers (from imported glass tubes), telescopes, surveying instruments and microscopes. Significance: With the rapid urban expansion, one of the most important needs of the new colony was to survey and map the landscape of the Australian Colony’s interior. Theodolites, such as this one, made by Troughton and Simms, who were significant scientific instrument makers of the 19th century were instrumental to the colony's surveyors and would have played an important part in their everyday work. This transit theodolite remains of national significance due to its pioneering role in Australian science and its association with Australia's earliest surveyors and astronomers. It is also significant for its association with nineteenth-century surveying instruments and instrument makers. Theodolite, Vernier repetition theodolite with enclosed horizontal circle (of about 130 mm diameter). Vertical circle exposed and somewhat corroded (diameter about 115 mm).

... scientific instrument maker... mother. Domeneck was also a scientific instrument maker. John B... mother. Domeneck was also a scientific instrument maker. John B ...Langlands Company History: Langlands foundry was Melbourne's first foundry and iron shipbuilder established in 1842, only 8 years after the founding of the Victorian colony by two Scottish immigrants, Robert Langlands and Thomas Fulton, who had formed a partnership before emigrating (1813–1859). The business was known as the 'Langlands Foundry Co'. Henry Langlands (1794-1863), left Scotland in 1846 with his wife Christian, née Thoms, and five surviving children to join his brother Robert. By the time he arrived in early January of 1847 the partnership of Robert Langlands and Fulton had dissolved as Fulton had gone off to establish his own works. It was at this time that the two brothers took over ownership of Langlands foundry. Several years later Robert retired and Henry became sole the proprietor. The foundry was originally located on Flinders Lane between King and Spencer streets. Their sole machine tool, when they commenced as a business, was a small slide rest lathe turned by foot. In about 1865 they moved to the south side of the Yarra River, to the Yarra bank near the Spencer Street Bridge and then in about 1886 they moved to Grant Street, South Melbourne. The works employed as many as 350 workers manufacturing a wide range of marine, mining, civil engineering, railway and general manufacturing components including engines and boilers. The foundry prospered despite high wages and the lack of raw materials. It became known for high-quality products that competed successfully with any imported articles. By the time Henry retired, the foundry was one of the largest employers in Victoria and was responsible for casting the first bell and lamp-posts in the colony. The business was carried on by his sons after Henry's death. The company was responsible for fabricating the boiler for the first railway locomotive to operate in Australia, built-in 1854 by Robertson, Martin & Smith for the Melbourne and Hobson's Bay Railway Company. Also in the 1860s, they commenced manufacture of cast iron pipes for the Board of Works, which was then laying the first reticulated water supply system in Melbourne. Langlands was well known for its gold mining equipment, being the first company in Victoria to take up the manufacture of mining machinery, and it played an important role in equipping Victoria's and Australia's first mineral boom in the 1850s and 1860s. Langlands Foundry was an incubator for several engineers including Herbert Austin (1866–1941) who worked as a fitter at Langlands and went on to work on the Wolesely Shearing machine. He also founded the Austin Motor Company in 1905. Around the 1890s Langlands Foundry Co. declined and was bought up by the Austral Otis Co. in about 1893. History for Grimoldi: John Baptist Grimoldi was born in London UK. His Father was Domeneck Grimoldi, who was born in Amsterdam with an Italian Father and Dutch mother. Domeneck was also a scientific instrument maker. John B Grimoldi had served his apprenticeship to his older brother Henry Grimoldi in Brooke Street, Holburn, London and had emigrated from England to Australia to start his own meteorological and scientific instrument makers business at 81 Queens St Melbourne. He operated his business in 1862 until 1883 when it was brought by William Samuel and Charles Frederick, also well known scientific instrument makers who had emigrated to Melbourne in 1875. John Grimoldi became successful and made a number of high quality measuring instruments for the Meteorological Observatory in Melbourne. The barometer was installed at Warrnambool's old jetty and then the Breakwater as part of the Victorian Government's insistence that barometers be placed at all major Victorian ports. This coastal barometer is representative of barometers that were installed through this government scheme that began in 1866. The collecting of meteorological data was an important aspect of the Melbourne Observatory's work from its inception. Just as astronomy had an important practical role to play in navigation, timekeeping and surveying, so the meteorological service provided up to date weather information and forecasts that were essential for shipping and agriculture. As a result, instruments made by the early instrument makers of Australia was of significant importance to the development and safe trading of companies operating during the Victorian colonies early days. The provenance of this artefact is well documented and demonstrates, in particular, the importance of the barometer to the local fishermen and mariners of Warrnambool. This barometer is historically significant for its association with Langlands’ Foundry which pioneered technology in the developing colony by establishing the first ironworks in Melbourne founded in 1842. Also, it is significant for its connection to John B Grimoldi who made the barometer and thermometer housed in the cast iron case. Grimoldi, a successful meteorological and scientific instrument maker, arrived in the colony from England and established his business in 1862 becoming an instrument maker to the Melbourne Observatory. Additional significance is its completeness and for its rarity, as it is believed to be one of only two extant barometers of this type and in 1986 it was moved to Flagstaff Hill Maritime Village as part of its museum collection. Coast Barometer No. 8 is a tall, red painted cast iron pillar containing a vertical combined barometer and thermometer. Half way down in the cast iron framed glass door is a keyhole. Inside is a wooden case containing a mercury barometer at the top with a thermometer attached underneath, each with a separate glass window and a silver coloured metal backing plate. Just below the barometer, on the right-hand side, is a brass disc with a hole for a gauge key in the centre. The barometer has a silvered tin backing plate with a scale, in inches, of "27 to 31" on the right side and includes a Vernier with finer markings, which is set by turning the gauge key. The thermometer has a silvered tin backing plate with a scale on the left side of "30 to 140". Each of the scales has markings showing the units between the numbers.Inscription at the top front of the pillar reads "COAST BAROMETER" Inscribed on the bottom of the pillar is "No 8". and "LANGLANDS BROS & CO ENGINEERS MELBOURNE " The barometer backing plate is inscribed "COAST BAROMETER NO. 8, VICTORIA" and printed on the left of the scale, has "J GRIMOLDI" on the top and left of the scale, inscribed "Maker, MELBOURNE". There is an inscription on the bottom right-hand side of the thermometer scale, just above the 30 mark "FREEZING" Etched into the timber inside the case are the Roman numerals "VIII" (the number 8)flagstaff hill, warrnambool, maritime village, maritime museum, flagstaff hill maritime museum & village, shipwreck coast, great ocean road, warrnambool breakwater, coast barometer, coastal barometer, barometer, weather warning, ports and harbours, fishery barometer, sea coast barometer, austral otis co, coast barometer no. 8, henry grimoldi, henry langlands, john baptist grimoldi, langlands foundry co, meteorological instrument maker, robert langlands, scientific instrument maker, thermometer, thomas fulton -

Instrument - Three draw Telescope, 20th century
... scientific instrument... scientific instruments in Liverpool. Between 1730 up too today... companies were making scientific instruments in Liverpool. Between ...This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. Many companies were making scientific instruments in Liverpool. Between 1730 up too today, they manufactured spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmoscopes, and electrical equipment such as electric lamps. Liverpool was a major centre for the production of scientific items rivaling Glasgow and London from 1850 to 1920. This telescope appears to be of quality manufacture but the origins can only be surmised at based on the gold embossing to the leather surrounding the main brass tube as being associated with Liverpool England. There is no maker or owners mark, so again there is no sure way to determine the year of manufacture or maker. There were many opticians and scientific instrument makers working in and around Liverpool from 1730 through too today. Also the possibility the telescope could have been made outside Liverpool overseas should not be overlooked and may have been made as a souvenir item from Liverpool from the mid to late 20th century. The size and type of telescope is a traditional type that was used for many sporting activities in the mid to late 19th century for deer stalking, bird watching, or used generally. I believe the item dates from sometime around the early to late part of the 20th century as the use of the liver bird mark became popular in 1911. It began appearing on many manufactured items of the period up too today, denoting that these items were made by companies operating in or around Liverpool England. If the item had been made by a notable firm it would have been engraved with the makers name city of origin, or owner as was the accepted practice for these items. The writer has been unable to determine if any specific company had had exclusive use of the liver bird logo as it was widely used and was not copyrighted until the Liverpool football club successfully won a court case giving them the sole rights to the trademark in 2012.The item is also an example of the shipwreck artefacts gathered along the southwest coast of Victoria. It is also a sample of scientific instruments used up to the mid 20th century.Victorian style gentleman's three draw brass telescope with machine milling surrounding the end of each tube and around the objective end. The three tube draw has no split and all three cartridges are held within the main brass tube wrapped in leather with rope bindings at both ends 5 cm in length and beginning 7 cm from the objective end. The last 2.8 cm makes up the remainder of the brass tube which has a sliding brass sunshade. The eyepiece is flat and has a protective slide over the lens aperture. Two relay lenses are missing on the ends of the second and third tube.

The Minnitt ...This Minnitt machine was owned by Dr Mary Clementina DeGaris. Dr DeGaris qualified from medicine, MB BS, at the University of Melbourne in 1905. She continued her studies, becoming only the second woman in Victoria to qualify MD, in 1907. With the outbreak of war, DeGaris attempted to enlist as a doctor with the Australian Army but was refused. Undeterred she travelled to England, where she joined the Scottish Women's Hospitals for Foreign Service, a medical group made up entirely of women. After the war, she returned to Australia and set up practice as an obstetrician in Geelong, Victoria. Subsequently, the Geelong Hospital named a wing after her, "DeGaris House", which is now part of Geelong Private Hospital. DeGaris was awarded the St Saba medal, 3rd class, for her work during WWI. Robert James Minnitt introduced the concept of self-administered analgesia, using an apparatus designed and built in conjunction with London scientific instrument-maker, Charles King. The Minnitt apparatus met with considerable success and led to further modifications, including the introduction of the Queen Charlotte gas-air analgesia apparatus in 1936.Brown leather suitcase with brass locks and leather handle. Inside the case is metal equipment, with arms for attaching cylinders. On top of the case, located underneath the handle, is a small brass plate, bearing the name of the owner in black printed script on a piece of card or paper held inside the plate.Printed in black ink on name plate: Dr Mary C.

A local manufacturer of scientific instruments ...Stick mercury barometer, named after Admiral Robert Fitzroy of the Royal Navy (1805 - 1865) for his detailed instructions on interpreting the weather that are included with the instrument. Fitzroy was the captain of the Beagle, a weather forecaster to Charles Darwin and the second Governor of New Zealand. He developed many different types of barometers and was the first person to introduce the science of weather forecasting to the British Isles. A local manufacturer of scientific instruments, Thomas Gaunt, produced the barometer and it was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. Described as "Gaunt's Fitzroy Barometers" in the original sale catalogue, it was priced from 25/- to ₤9.9s. [See Miller, M., Gaunt’s Time, 2014]. Thomas Gaunt's business was originally located at 14 Bourke Street East from 1858. In 1869-1870 he moved to new premises in the Royal Arcade, Collins Street. Gaunt's business became an institution in Victorian Melbourne and Gaunt its leading clock maker. PROVENANCE According to official minutes the barometer was purchased by the Melbourne Athenaeum in 1874. In particular, at the March meeting of the General Committee the House Subcommittee was instructed to "obtain a Fitzroy or other reliable barometer" to be "fixed in the Reading Room". The 1874 Annual Report records the purchase at ₤3.10.0. The barometer is historically significant as an example of the work of Melbourne’s leading scientific instrument maker, Thomas Gaunt. The barometer has social significance as an example of the type of accoutrements provided by the committee of the Melbourne Athenaeum for the comfort of its members. Further social significance lies in the fact that Robert Ellery, the Government Astronomer, who designed the local version of the barometer, has a direct connection with the Athenaeum being a subscription member and committee member of the Athenaeum during the 1870s. There are also records of a T Gaunt as a subscription member of the Athenaeum during the 1870s and 1880s which may be Thomas Gaunt, however, this is yet to be verified. Stick mercury barometer known as the Admiral Fitzroy Barometer. It comprises an oblong wooden case with glass front panel, ornate pediment, barometer with bulb cistern (empty of fluid),printed instructions for interpreting information given by the gauge affixed to left and right face of instrument. Includes a thermometer. The barometer appears to be intact except for the turning knobs which are missing and the mercury in the tube which is not present.

... and scientific instruments at these meetings. Throughout its long trading... and scientific instruments at these meetings. Throughout its long trading ...James Henry Steward (1817–1896) established J.H. Steward in London in 1852. As “Head Optician” he would have been a qualified oculist but little is known about the founder’s early life and scholastic achievements. However, given the variety of disciplines for which he undertook he was also an accredited instrument maker,he clearly was a gifted scholar and quickly gained professional recognition in a full range of fields for an instrument maker of his day. J.H Steward became incorporated as J.H. Steward Limited on 1st February,1913. The business grew from modest beginnings. Steward would sell pocket watches and assorted items at the annual competition days of "The National Rifle Association of the United Kingdom(NRA)" from a stall. As the governing body for full bore rifle and pistol shooting sports in the UK. The Association established in 1859 with the aim to improve the shooting skills of the newly formed corps of volunteers to meet the perceived threat of an invasion by the French. J.H. Steward advert first appeared in the NRA competition program of 1865. The NRA meetings were held at first on Wimbledon Common, Surrey until 1889. Then because of pressure by the local community, the NRA along with its buildings and its flourishing meetings moved further south to Brookwood, Surrey. By now the Steward operation had grown from a modest stall into a large marquee selling various optical and scientific instruments at these meetings. Throughout its long trading history the J.H. Steward company and many members of the family maintained strong ties to the NRA and competition shooting events. The NRA records show that at the end of the 19th century the NRA bestowed a Life Membership on 7 Steward family members. First presented by J. H. Steward Ltd. in 1902 was the “Steward Trophy” that is still an annual competition for teams of four from any rifle club affiliated to the NRA. There is also evidence that many family members were fine shots.The item was made by a significant instrument manufacturing company that concentrated during the middle 19th century on supplying the British military. This items pattern & design is still available as a reproduction, available on the internet. However this original seems unique as the writer cannot find another for sale or in a collection to date. The assumption is that this type of compass was made for the British artillery units given the sun dial.

Octant, Mid to late 19th Century
... in the history of scientific instruments in the eighteenth and nineteenth... in the history of scientific instruments in the eighteenth and nineteenth ...An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

Instrument - Sextant, Late 20th Century
... In 1941, the scientific instrument manufacturing firms... Warrnambool great-ocean-road In 1941, the scientific instrument ...In 1941, the scientific instrument manufacturing firms of Henry Hughes & Son Ltd, London, England, and Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.

Instrument - Azimuth Compass, Early 20th Century
... of financial institutions in the form of Western Scientific Instruments... in the form of Western Scientific Instruments and in 1985 the company ...Negretti and Zambra 1850-1980s were optical instrument makers and mathematical instrument makers based in London, England. The firm of Negretti and Zambra was established in 1850 by Henry Negretti and Joseph Zambra who had formed a partnership. Their skill was immediately apparent when exhibiting at the 1851 Great Exhibition at Hyde Park, they were the only English instrument makers to receive a prize medal for meteorological instruments, resulting in their appointment as instrument makers to the queen, Greenwich observatory, and the British Meteorological Society. In 1853, when the Crystal Palace was re-erected in Sydenham, Negretti and Zambra became the official photographers of the Crystal Palace Company, which allowed them to photograph the interior and grounds of the new building. The firm made use of this access to produce a number of stereographs. Between 1855 and 1857 Negretti and Zambra commissioned photographer Pierre Rossier to travel to China to document the Second Opium War. Although Rossier subsequently was unable to accompany to Anglo-French forces in that campaign, he nevertheless produced a number of stereographs and other photographs of China, Japan, the Philippines and Siam (now Thailand), which Negretti and Zambra published and that represented the first commercial photographs of those countries. In 1856 Negretti and Zambra sponsored a photographic expedition to Egypt, Nubia and Ethiopia conducted by Francis Firth. In 1864 Negretti and Zambra (themselves) photographed Shakespeare's House at Stratford on Avon. A sepia photograph was then pasted onto card 4" × 2.5". This was then presented to visitors to the Crystal Palace to enable them to compare it with the model erected by Mr E. T. Parr in the Centre Transept. The card itself is headed "Crystal Palace April 23rd 1864." That year they also published a book, titled A Treatise on Meteorological Instruments, (which was reprinted in 1995). Throughout World War One Negretti and Zambra were entirely engaged in the production of various instruments for the Ministry of Munitions. They developed many instruments for the Air Ministry including a mercury-in-steel distance thermometer for taking the oil and air temperatures in aircraft which was patented in 1920. In 1946 the company went private and in 1948 the company was made public, and by 1950 Negretti and Zambra had 821 employees in Britain. In order to increase production and to safeguard future development in 1964, they purchased a modern factory at Aylesbury for all their production. In 1981 Negretti and Zambra were taken over by a group of financial institutions in the form of Western Scientific Instruments and in 1985 the company was acquired by Meggitt Holdings.The subject compass is just one type of the many marine and scientific, optical items this company produced over it’s life time. Negretti and Zambra were prolific manufactures of types of items as well as being very prominent in photography pioneering new innervation's and sponsoring expeditions to little known countries to document peoples daily lives and culture through photography.Azimuth compass on tripod in a fitted wooden box with a round spirit level included, lid of box has three indented circles where the legs of the compass fit when it is set up for use.

Tool - Plane, 1819-1901
... worked initially in the workshop of the scientific-instrument... of the scientific-instrument maker Jesse Ramsden, Anglicizing his name ...A moulding plane is a specialised plane used for making the complex shapes found in wooden mouldings that are used to decorate furniture or other wooden objects. Traditionally, moulding planes were blocks of wear-resistant hardwood, often beech or maple, which were worked to the shape of the intended moulding. The blade or iron was likewise formed to the intended moulding profile and secured in the body of the plane with a wooden wedge. A traditional cabinetmakers shop might have many, perhaps hundreds, of moulding planes for the full range of work to be performed. Large crown mouldings required planes of six or more inches in width, which demanded great strength to push and often had additional peg handles on the sides, allowing the craftsman's apprentice or other workers to pull the plane ahead of the master who guided it. Company History: The Holtzapffel dynasty of tool and lathe makers was founded in Long Acre, London by a Strasbourg-born turner, Jean-Jacques Holtzapffel, in 1794. The firm specialized in lathes for ornamental turning but also made a name for its high-quality edge and boring tools. Moving to London from Alsace in 1792, Jean-Jacques worked initially in the workshop of the scientific-instrument maker Jesse Ramsden, Anglicizing his name to John Jacob Holtzapffel. In 1794 he set up a tool-making partnership in Long Acre with Francis Rousset and they began trading under the name of John Holtzapffel. From 1804 he was in partnership with the Mannheim-born Johann Georg Deyerlein until the latter died in 1826, trading under the name Holtzapffel & Deyerlein. Holtzapffel sold his first lathe in June 1795, for £25-4s-10d, an enormous price at the time. All of Holtzapffel's lathes were numbered and by the time he died in 1835, about 1,600 had been sold. The business was located at 64 Charing Cross, London from 1819 until 1901 when the site was required "for building purposes". The firm then moved to 13 and 14 New Bond Street and was in premises in the Haymarket from 1907 to 1930. John's son, Charles Holtzapffel (1806–1847) joined the firm in 1827, at around which time the firm became known as Holtzapffel & Co. Charles continued to run the business after his father's death. He wrote a 2,750-page treatise entitled Turning and Mechanical Manipulation, published in 1843 which came to be regarded as the bible of ornamental turning. The final two volumes were completed and published after his death by his son, John Jacob Holtzapffel (1836–1897). When Charles Holtzapffel died in 1847 his wife Amelia ran the business until 1853. John Jacob II, the son of Charles and Amelia, was head of the firm from 1867 until 1896. A nephew of John Jacob II, George William Budd (1857–1924) became head of the firm in 1896. His son John George Holtzapffel Budd (1888–1968) later ran the business. By the early twentieth century, ornamental turning was going out of fashion, and the firm sold its last lathe in 1928. A vintage tool made by a well-known firm made for firms and individuals that worked in wood. The tool was used before routers and spindle moulders came into use after World War ll, a time when to produce a decorative moulding for a piece of furniture or other items this had to be accomplished by hand using one of these types of planes. A significant item from the mid to late 19th century that today is quite rare and sought after by collectors. It gives us a snapshot of how furniture was made predominately by hand and with tools that were themselves hand made shows the craftsmanship used to make such a unique item.

From 1804 he was in partnership with the Mannheim-born Johann Georg Deyerlein until the latter died in 1826, trading under the name Holtzapffel & Deyerlein. Holtzapffel sold his first lathe in June 1795, for £25-4s-10d, an enormous price at the time. All of Holtzapffel's lathes were numbered and by the time he died in 1835, about 1,600 had been sold. The business was located at 64 Charing Cross, London from 1819 until 1901 when the site was required "for building purposes". The firm then moved to 13 and 14 New Bond Street and was in premises in the Haymarket from 1907 to 1930. John's son, Charles Holtzapffel (1806–1847) joined the firm in 1827, at around which time the firm became known as Holtzapffel & Co. Charles continued to run the business after his father's death. He wrote a 2,750-page treatise entitled Turning and Mechanical Manipulation, published in 1843 which came to be regarded as the bible of ornamental turning. The final two volumes were completed and published after his death by his son, John Jacob Holtzapffel (1836–1897). When Charles Holtzapffel died in 1847 his wife Amelia ran the business until 1853. John Jacob II, the son of Charles and Amelia, was head of the firm from 1867 until 1896. A nephew of John Jacob II, George William Budd (1857–1924) became head of the firm in 1896. His son John George Holtzapffel Budd (1888–1968) later ran the business. By the early twentieth century, ornamental turning was going out of fashion, and the firm sold its last lathe in 1928. A vintage tool made by a well-known firm made for firms and individuals that worked in wood. The tool was used before routers and spindle moulders came into use after World War ll, a time when to produce a decorative moulding for a piece of furniture or other items this had to be accomplished by hand using one of these types of planes. A significant item from the mid to late 19th century that today is quite rare and sought after by collectors. It gives us a snapshot of how furniture was made predominately by hand and with tools that were themselves hand made shows the craftsmanship used to make such a unique item.

Functional object - Spectacles and Case, Carter & Foord, 1902-1930s
... , oculists, watchmakers and jewellers. The staff repaired scientific... scientific instruments and were sole agents for the gramophone ...The spectacles and case are an example of eyewear from the early 20th century. The case was made by Carter & Foord of Ballarat. According to the tag inside, the spectacles frame cost three pounds, three shillings and sixpence (£3.3.6). Carter & Foord was established in 1902. The firm advertised as opticians, oculists, watchmakers and jewellers. The staff repaired scientific instruments and were sole agents for the gramophone, demonstrating its advantages whenever there was an opportunity. In 1902 the business was located at 46 Lydiard Street, Ballarat. The staff in the ophthalmic department, under the care of Harold Foord, specialised in sight testing using up-to-date equipment and this service was free of charge. Customers were promised that they would be fitted with glasses guaranteed to correct the most complex sight. Mr F M Clacius performed the grinding of specific lenses. Julia Carter, Harold Foord and Clacius were all formerly from the business Carter & Warner, which had been sold to Frederick Clark around 1903 after Mr Carder passed away. Carter & Foord operated a few doors away from the former business. In 1912 advertisements in the Geelong Advertiser invited the community to visit Harold Foord, of Carter & Foord, to have their eyes examined at no charge. These spectacles are similar to others in the W.R. Angus collection, donated by the family of Dr W R Angus, surgeon and oculist. The W.R. Angus Collection spans the years 1885 to the mid-1900s and includes historical medical and surgical equipment and instruments from the doctors Edward and Thomas Ryan of Nhill, Victoria, with whom Dr Angus worked for several years. Dr Tom and his brother had worked as surgeons including in eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. Dr Angus married Gladys in 1927 at Ballarat, the nearest big city to Nhill where he began as a Medical Assistant and had been Acting House surgeon at the Nhill hospital where their two daughters were born. Dr Angus and his family moved to Warrnambool in 1939, where Dr Angus operated his own medical practice. He later took on the part-time role of Port Medical Officer and was the last person appointed to that position. After convalescing from injury resulting from his service during WWII, Dr Angus studied ophthalmology at the Royal Melbourne Eye and Ear Hospital. He created cosmetically superior artificial eyes by pioneering the use of intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering artificial eye improvements. He had been an Honorary Consultant Ophthalmologist at Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. Both Dr Angus and his wife were very involved in the local community, including the planning stages of the new Flagstaff Hill and the layout of the gardens there. Dr Angus passed away in March 1970.The Carter &O Foord spectacles are significant as an example of early 20th-century eyewear and fashion. They are connected to the history of regional Victoria, being made in Ballarat and purchased for local use. The spectacles are significant for being connected to the W.R. Angus Collection, which is important for still being located at the site connected to Doctor Angus, Warrnambool’s last Port Medical Officer. Dr Angus and his wife brought their young family to Warrnambool in 1938 and he remained a resident until his death in 1970. Early in his profession in the town of Nhill, Dr Angus assisted Dr Tom Ryan in his pioneering use of X-rays and in ocular surgery, and Dr Angus later inherited these items. The W.R. Angus Collection includes these medical instruments and other related equipment and is culturally and historically significant as an example of the medical practice of the late 19th to the mid-20th century. Other items in the collection relate to Dr Angus’ service in the Flying Doctor Service and the Army.Spectacles in a hard brown textured case with rounded corners and a hinged lid. The case is lined with brown velvet. The opaque yellow oval frames, raised at the outer top corners, are decorated with sparkling jewell decorations on the bridge. The arms are reinforced with metal inside. Also in the case is a pale blue cleaning cloth and a cardboard price tag with handwritten text. An inscription in gold lettering is stamped inside the case.

Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

Compass, 1947-1950
... scientific instrument... in London as a maker of chronographic and scientific instruments... in London as a maker of chronographic and scientific instruments ...Kelvin Company History: The origins of the company lie in the highly successful, if strictly informal, the relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, who was an optical instrument maker in Glasgow in 1850. He was involved in supplying and mending apparatus for Thomson's university laboratory and working with him on experimental constructions. White was actually declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson's laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson's design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company). Thomson, who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death in 1884, raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd . Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd . Hughes Company History: Henry Hughes & Sons was founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as Henry Hughes & Sons Ltd in 1903. In 1923, the company produced its first recording echo sounder and in 1935, a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing Marine Instruments Ltd. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd., Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military use. This model compass is a good example of the commercial type of instruments made by Kelvin & Hughes after the world war 2, it was made in numbers for use on various types of shipping after the second world war and is not particularly rare or significant for it's type. Also it was made no earlier than 1947 as the firms of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd who took over from Smith & Sons were not amalgamated until 1947. Given that Smith and Sons is engraved on the compass with Kelvin & Hughes it can be assumed that this compass was made during the company's transitional period to Kelvin & Hughes.Compass, marine or ship's card compass, gimble mounted, with inscriptions.

One long edge is used with the compass rose on the chart, aligning the centre of the rose with the desired direction around the edge of the rose. The compass bars are then ‘walked’ in and out across the map to the desired location so that lines can be plotted to represent the direction to be travelled.
