Adams jnr wrote many elementary scientific works, as well as on the use of mathematical instruments. He often combined in his written works with religious themes and scientific content, often against the prevailing thoughts of the time. According to one popular magazine of the time (Gentleman's Magazine), his works were often accused of "growing errors of materialism, infidelity, and anarchy". He started writing at a young age and developed a love for it, his main interests included math and science, these subjects he often expressed in his written essay's. Notable works from Adams are. An Essay on Electricity, and Magnetism (1784). Essays on the Microscope (1787). An Essay on Vision, briefly explaining the fabric of the eye (1789). Astronomical and Geographical Essays (1790). A Short Dissertation on the Barometer (1790). Geometrical and Graphical Essays, containing a description of the mathematical instruments used in geometry, civil and military surveying, leveling and perspective (1790). Lectures on Natural and Experimental Philosophy, in five volumes (1794).George Adams Sr and Jnr were both notable opticians and scientific instrument makers of the 18th century.

The firm Dring and Fage were active from 1790 to 1940 in London and were manufacturers of hydrometers and mathematical instruments they became established in London in 1790 by John Dring, who was a brass worker and hydrometer maker, and William Fage. Dring and Fage manufactured also saccharometers and other instruments used to measure the strength of alcohol. These instruments were primarily used to calculate excises. They traded at various addresses in London and they were at 56 Stamford St. between 1903 and 1938. By 1850 the company was owned by Edward Hall and Edward Jenkin and in 1940 the company became Dring & Fage Ltd, trading till the 1960s. Historically, gauging has meant measuring a volume, these gauging instruments were used by Customs and Excise and manufacturers for determining the volume and contents of liquid containers. For Customs the determination and collection of duty on imported goods which has had a very long history. Chaucer was a Customs Officer as was his father and grandfather, excise was first officially introduced in 1643, with the aim of maintaining military forces raised by the English Parliament at that time. Excise was initially a duty on home produced alcoholic beverages and soap but being easily applied, spread rapidly to a wide range of goods including imports of varying kinds. The government departments of Customs and Excise merged only in 1909 and it is from around this time that our instrument was made and used. The item demonstrates a long social history of the practice of Government's collecting duty on alcoholic beverages and thereby makes this item historically significant as it was used locally at Port Fairy by the ports Customs agents.

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.

The steam engine indicator, or dynamometer, is an instrument used on a steam engine (such as that of a vessel or train) to measure and record the change in the pressures of the engine’s cylinders during their operating cycle. The engineer would use it to identify problems or defects such as bad valve settings or constricted steam pipes. It could indicate the difference in efficiency caused by adjustments made to the engine, being able to instantly measure the variation of pressure from the engine stroke at any given time. This force of power would be registered by a pencil, fitted to the adjustable arm, which would trace a line on paper wound around the cylinder. The recorded information could be used in conjunction with mathematical tables. This particular instrument was made by T.S. Mc Innes, one of the better manufacturers of engine indicators. Mc Innes engine indicators were still being used in the mid 1900’s. This specific instrument was used by Mark Forsythe of North Berwial, Scotland and late of Ararat, Victoria when he was chief engineer on the “SS Talawena” in 1892. The Port of Warrnambool, in Victoria, harboured steam ships that carried both passengers and cargo along the south west coast in the late 1800’s and into the 1900’s. The engineer of a steam ship was responsible for reaching and maintaining the optimum level of steam energy to serve the locomotion and efficiency of the steam ship. The engineer would use a steam engine indicator to measure and record information to achieve this purpose. Engine Dynamometer or Steam Engine Indicator in square, fitted oak case. This brass instrument is used to measure and record steam pressure for setting up and adjusting valves on a steam engine. It has an oscillating recording drum with vertical, silver clip attached for holding paper in place around the drum. The drum oscillates left to right. There is a pulley attached to a length of cord, which is attached to the drum. Beside the drum is a fine metal arm, vertically adjustable, small hole in the end to hold a pencil. Inscription stamped into bracket of the arm. The engine indicator is mounted on a hinged side of the case that swings out ready for use. Attached chains prevent the side from opening past vertical. There is storage for other accessories and an empty compartment in the base (where a scale or ruler may have been located). The case has a collapsible wooden handle, brass hinges and two brass, hook-shaped catches. There is a code stamped inside the lid. It contains a brass, ‘T’ shaped steam-cock (or stop cock) with two open ends made of metal pipe with different sized threads. (Turning the handle on top opens and closes the space in the pipe and would close off the flow of steam from one end to the other.) Also inside the case are three different spiral springs, each with a threaded nut on the end that has a threaded hole inside it. Used by Mr Mark Forsythe when chief engineer on the SS Talawena in 1892 “T.S. MC INNES PATENT” and “522 _ _” (last 2 digits are unreadable) pressed into the arm of the brass indicator. “[ ] X ’ stamped inside the lid of the case.

The beginning of standardised weights and measures began In Victoria when the Melbourne Observatory received sets of standard weights and measures, which had been tested in Britain against the then British Imperial standards. These included the primary standard yard and pound for the Colony of Victoria. Other standards of weights and measure held by shires and the administrative body's within the colony could then be compared to these primary standards. A Weights and Measures Act was passed in Victoria in 1862, establishing local inspectors throughout the colony. By the 1870s each local council and shire in Victoria held a set of standards that were used to test scales, weights and dry measures used by wholesalers, factories and shops. Every ten years the councils’ standards would themselves need to be rechecked against the Victorian Standards. The checking was done by the Victorian Customs Department in the 19th century, but with the transfer of responsibility for customs to the Federal Government in 1901, weights and measures function was retained by the Victorian Government and was shifted to the Melbourne Observatory. In 1904, a new building was erected at the south end of the Great Melbourne Telescope House, where the standard weights and measures and testing equipment was installed. This room had a large whirling apparatus for testing air meters and became known as the Whirling Room. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue and this branch remained at the Observatory site unit until 1995. J & M Ewan History: J&M Ewan was a Melbourne firm that began by selling retail furniture and wholesale ironmongery. They had substantial warehouses situated at the intersection of 81-83 Elizabeth and Little Collins Streets, the business was established by James M Ewan in 1852. Shortly afterwards he went into partnership with William Kerr Thomson and Samuel Renwick. When Ewan died in 1868 his partners carried on and expanded the business under his name J & M Ewan. The business was expanded to provide a retail shop, counting-house and private offices. Wholesale warehouses adjoined these premises at 4, 6 and 10 Little Collins Street, West. This company provided and sold a large and varied amount of imported goods into the colony that consisted of agriculture equipment, building materials, mining items as well as steam engines, tools of all types and marble fireplaces. They also supplied the Bronze measuring containers in the Flagstaff Hill collection and the probability is that these containers were obtained by the local Melbourne authority that monitored weights and measures in the mid to late 19th century. The company grew to employ over 150 people in Melbourne and opened offices at 27 Lombard St London as well as in New Zealand and Fiji. The company also serviced the Mauritius islands and the pacific area with their steamship the Suva and a brig the Shannon, the company ceased trading in 1993. Robert Bate History: Robert Brettell Bate (1782-1847) was born in Stourbridge, England, one of four sons of Overs Bate, a mercer (a dealer in textile fabrics, especially silks, velvet's, and other fine materials)and banker. Bate moved to London, and in 1813 was noticed for his scientific instrument making ability through the authority of the “Clockmakers Company”. Sometime in the year 1813 it was discovered that one Robert Brettell Bate, regarded as a foreigner in London had opened a premises in the Poultry selling area of London. He was a Mathematical Instrument maker selling sundials and other various instruments of the clock making. In 1824, Bate, in preparation for his work on standards and weights, leased larger premises at 20 and 21 Poultry, London, at a rental of four hundred pounds per annum. It was there that Bate produced quality metrological instruments, which afforded him the recognition as one of one of the finest and principal English metrological instrument-makers of the nineteenth century. English standards at this time were generally in a muddle, with local standards varying from shire to shire. On 17 June 1824, an Act of Parliament was passed making a universal range of weights, measures, and lengths for the United Kingdom, and Bate was given the job of crafting many of the metrological artifacts. He was under instruction from the renown physicist Henry Kater F.R.S. (1777-1835) to make standards and to have them deposited in the principal cities throughout the United Kingdom and colonies. Bate experimented with tin-copper alloys to find the best combination for these items and by October 1824, he had provided Kater with prototypes to test troy and avoirdupois pounds, and samples with which to divide the troy into grams. Bate also cast the standard for the bushel, and by February 1825, had provided all the standards required of him by the Exchequer, Guildhalls of Edinburgh, and Dublin. In 1824, he also made a troy pound standard weight for the United States, which was certified for its accuracy by Kater and deposited with the US Mint in 1827. Kater, in his address to the Royal Society of London, acknowledged Bate's outstanding experimentation and craftsmanship in producing standards of weights, measures, and lengths. An example of a dry Bronze measuring container made specifically for J & M Ewan by possibly the most important makers of measurement artefacts that gives us today a snapshot of how imperial weights and measures were used and how a standard of measurement for merchants was developed in the Australian colonies based on the Imperial British measurement system. The container has social significance as an item retailed by J & M Ewan and used in Victoria by the authorities who were given legal responsibility to ensure that wholesalers and retailers of dry goods sold in Victoria were correct. The container was a legal standard measure so was also used to test merchants containers to ensure that their distribution of dry goods to a customer was correct.Maker Possibly Robert Brettell Blake or De Grave, Short & Co Ltd both of LondonContainer bronze round shape for measuring dry quantities has brass handles & is a 'half-bushel' measurement"IMPERIAL STANDARD HALF BUSHEL" engraved around the top of the container.

Bate also cast the standard for the bushel, and by February 1825, had provided all the standards required of him by the Exchequer, Guildhalls of Edinburgh, and Dublin. In 1824, he also made a troy pound standard weight for the United States, which was certified for its accuracy by Kater and deposited with the US Mint in 1827. Kater, in his address to the Royal Society of London, acknowledged Bate's outstanding experimentation and craftsmanship in producing standards of weights, measures, and lengths.

The beginning of standardised weights and measures began In Victoria when the Melbourne Observatory received sets of standard weights and measures, which had been tested in Britain against the then British Imperial standards. These included the primary standard yard and pound for the Colony of Victoria. Other standards of weights and measure held by shires and the administrative body's within the colony could then be compared to these primary standards. A Weights and Measures Act was passed in Victoria in 1862, establishing local inspectors throughout the colony. By the 1870s each local council and shire in Victoria held a set of standards that were used to test scales, weights and dry measures used by wholesalers, factories and shops. Every ten years the councils’ standards would themselves need to be rechecked against the Victorian Standards. The checking was done by the Victorian Customs Department in the 19th century, but with the transfer of responsibility for customs to the Federal Government in 1901, weights and measures function was retained by the Victorian Government and was shifted to the Melbourne Observatory. In 1904, a new building was erected at the south end of the Great Melbourne Telescope House, where the standard weights and measures and testing equipment was installed. This room had a large whirling apparatus for testing air meters and became known as the Whirling Room. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue and this branch remained at the Observatory site unit until 1995. J & M Ewan History: J&M Ewan was a Melbourne firm that began by selling retail furniture and wholesale ironmongery. They had substantial warehouses situated at the intersection of 81-83 Elizabeth and Little Collins Streets, the business was established by James M Ewan in 1852. Shortly afterwards he went into partnership with William Kerr Thomson and Samuel Renwick. When Ewan died in 1868 his partners carried on and expanded the business under his name J & M Ewan. The business was expanded to provide a retail shop, counting-house and private offices. Wholesale warehouses adjoined these premises at 4, 6 and 10 Little Collins Street, West. This company provided and sold a large and varied amount of imported goods into the colony that consisted of agriculture equipment, building materials, mining items as well as steam engines, tools of all types and marble fireplaces. They also supplied the Bronze measuring containers in the Flagstaff Hill collection and the probability is that these containers were obtained by the local Melbourne authority that monitored weights and measures in the mid to late 19th century. The company grew to employ over 150 people in Melbourne and opened offices at 27 Lombard St London as well as in New Zealand and Fiji. The company also serviced the Mauritius islands and the pacific area with their steamship the Suva and a brig the Shannon. Robert Bate History: Robert Brettell Bate (1782-1847) was born in Stourbridge, England, one of four sons of Overs Bate, a mercer (a dealer in textile fabrics, especially silks, velvet's, and other fine materials)and banker. Bate moved to London, and in 1813 was noticed for his scientific instrument making ability through the authority of the “Clockmakers Company”. Sometime in the year 1813 it was discovered that one Robert Brettell Bate, regarded as a foreigner in London had opened a premises in the Poultry selling area of London. He was a Mathematical Instrument maker selling sundials and other various instruments of the clock making. In 1824, Bate, in preparation for his work on standards and weights, leased larger premises at 20 and 21 Poultry, London, at a rental of four hundred pounds per annum. It was there that Bate produced quality metrological instruments, which afforded him the recognition as one of one of the finest and principal English metrological instrument-makers of the nineteenth century. English standards at this time were generally in a muddle, with local standards varying from shire to shire. On 17 June 1824, an Act of Parliament was passed making a universal range of weights, measures, and lengths for the United Kingdom, and Bate was given the job of crafting many of the metrological artifacts. He was under instruction from the renown physicist Henry Kater F.R.S. (1777-1835) to make standards and to have them deposited in the principal cities throughout the United Kingdom and colonies. Bate experimented with tin-copper alloys to find the best combination for these items and by October 1824, he had provided Kater with prototypes to test troy and avoirdupois pounds, and samples with which to divide the troy into grams. Bate also cast the standard for the bushel, and by February 1825, had provided all the standards required of him by the Exchequer, Guildhalls of Edinburgh, and Dublin. In 1824, he also made a troy pound standard weight for the United States, which was certified for its accuracy by Kater and deposited with the US Mint in 1827.

George Lee Lawrence (1901–1976) established a firm in Chicago to make slide rules for photography. In 1935 he moved to Wabash, Ind., renamed the company Lawrence Engineering Service, and began to manufacture general purpose slide rules. In 1938 he relocated once more to Peru, Ind., and in 1947 it was changed to Engineering Instruments, Inc., and the company remained in business until its building burned down in 1967. The model 10-B sold for 25 cents during this period. There is no record that Lawrence ever received a patent for any aspect of his design or manufacturing process.Used up to the 1960s prior to the invention of the electronic calculator.10 inch one-sided wooden slide rule painted white on the front face, which consists of two divided scales, one fixed and on movable, and a sliding window called a cursor.

A slide rule is an instrument which is used to carry out mathematical calculations. William Oughtred is credited with its invention in 1621, however many others including Isaac Newton have made improvements or modifications over the years. From 1625 to 1800 there were approximately 40 different styles brought forward. with the following 100 years sees over 250 designs created.There have been different versions and modifications to suit scientific, mathematical and engineering requirements. It is interesting to note that many of the buildings of the 19th and 20th centuries have been designed with the use of slide rules. Their use has declined in the last 25-30 years with the advent of computers and specialist calculators.While not directly linked in any way to the history of Warrnambool, this slide rule would have been a item in use by students doing maths at upper secondary level as well as other applications which would make it a familiar object to many people.Coated bamboo with sliding metal framed glass panel or cursor .

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.

In February 1913 the Ballarat Junior Technical School opened its doors to its 86 pupils. The old bluestone building in the grounds of the Dana Street Primary School became their temporary for eight years. In its early years the school offered only a two-year course. The first year was of a general nature giving a thorough grounding in Mathematics and Instrumental Drawing, and introducing students to the various branches of trade work. The second-year students studied for the Junior Technical Certificate and specialized in a course of their choice - either a trade (Woodwork or Fitting and Turning) or a course leading to higher studies at the School of Mines. The photograph shows the students outside the school building. Musical instruments, trophy and shield are shown. When World War 1 began, the school formed a 16 piece Bugle Band. A squad of Junior Cadets led by Mr A Williams and later Mr H Wakeling competed at the South Street contests.

Not much is known about William Rothwell other than he is recorded as working as an optician and scientific instrument maker in Manchester at 277 Deansgate Street from 1780 until 1820. An entry in the “Complete History of the Trades of Manchester” published in 1822, in which the author describes Mr William Rothwell as an intelligent young man who is conversant in several languages. He went on to describe him as an philosophical instrument maker of optical and mathematical objects, specialising in spectacles, all sorts of surveyors instruments as well as eye glasses of all types. At present that is all that is known of William Rothwell other than his products were made to the highest standards of the time. Today his products are now actively sought by collectors and are currently fetching high prices at auction sales overseas. The telescope is a rare item even though not much is known about Rothwell's history his scientific instruments and optical items fetch high prices when they become available as collectors look for rare and well made items from the 18th and 19th centuries. Its completeness and good condition make it a very good addition to the collection at Flagstaff Hill.
