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.

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 .

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.

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.

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.

This mid-19th century scientific reference book, Introduction to Modern Geography, explains geography and astronomy using the globe of the world as a teaching aid. The inscription connects this book to the Bobinawarrah Public Library but research to date has found no further details about the library. The rural area was settled in 1859, but in 2016 its population was only 87. It is situated about 21 kilometres south of the City of Wangaratta, in Northeast Victoria. In 2024 the local community received a grant for preservation of its almost 100-year-old Bobinawarrah Memorial Hall which displays an honour board of the Pioneers of Bobinawarrah 1859-1959. The donor of the book lived in Warrnambool. ABOUT THE AUTHOR, James Thomson (1786-1849): - James Thomson was a British Irish mathematician. He became Professor of Mathematics at the University of Glasgow. He wrote many school textbooks and reference books, one of which was Introduction to Modern Geography, first published in Belfast in 1827, and revised and published in over 20 more editions. Thomson tutored two of his several children at home. His older son James Thomson (1822-1892) became an engineer and physicist. His younger son William Thomson (1824-1907) became Professor of Natural Philosophy from 1846-1899 at the University of Glasgow, and later the 1st Baron of Kelvin, famous for his designs of nautical instruments such as the navigational compass and sounding equipment used in the transatlantic installation of sea cable. William was part of the firm that became famous as Kelvin & Hughes Ltd., suppliers of radar and echo sounders to the Ministry of Transport and the Ministry of Defence. The name continued on as Kelvin & Hughes. James Thomson (1786-1849) was a renowned British Irish mathematician and Professor of Mathematics at the University of Glasgow. He was a respected author of many important school books and textbooks that were widely used to provide understanding of arithmetic and geography. Thomson encouraged practical education and held extra classes for young ladies to learn mathematics and geography, which were a novelty at that time. Many of his works were known and used worldwide. This work was published in many editions. It is now considered as culturally significant as a basis for knowledge about our civilisation and has been made publicly available in overseas countries, and republished and reproduced in a readable format, including its diagrams and maps. Book; scientific textbook. The book has a black leather cover. The front cover is blank, but the spine has an embossed gold vertical title within a rectangular border boasting fancy corners.

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. Mr A Steane (the Headmaster) is shown to the right of the bass drum.Black and white copy of original photograph that is mounted on brown card.

The Fuller cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long. It was invented in 1878 by George Fuller, professor of engineering at Queen's University Belfast, and despite its size and price it remained on the market for nearly a century because it outperformed nearly all other slide rules. He patented it in Britain in 1878, described it in a journal in 1879 and in that year he also patented it the United States, depositing a patent model. As with other slide rules, the Fuller is limited to calculations based on multiplication and division with additional scales allowing for trigonometrical and exponential functions. The mechanical calculators produced in the same era were generally restricted to addition and subtraction with only advanced versions, like the Arithmometer, able to multiply and divide. Even these advanced machines could not perform trigonometry or exponentiation and they were bigger, heavier and much more expensive than the Fuller. In the mid-twentieth century the handheld Curta mechanical calculator became available which also competed in convenience and price. However, for scientific calculations the Fuller remained viable until 1973 when it was made obsolete by the HP-35 handheld scientific electronic calculator. Fuller's calculators were manufactured by the scientific instrument maker W.F. Stanley & Co. of London who made nearly 14,000 between 1878 and 1973.Like all slide rules, logarithmic scales are used to facilitate calculations more quickly and efficiently. The spiral logarithmic scale greatly increases the precision and computing power of the slide rule. In addition, its tables provide useful information to its users, most likely engineers. Its remarkable length permitted a high level of precision in calculations; calculations could be made to 4 or 5 significant digitsThe fuller calculator, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. There is a papier-mache cylinder fastened to a mahogany handle. A second papier-mache cylinder is a slide fit over the first. Both cylinders are covered in paper varnished with shellac. A brass pointer with an engraved index marker at its tip is attached to the handle and a second brass pointer is attached to the top cap. On the outer cylinder is a helical logarithmic scale 500" (41'8" or about 12.5 m) in length. This cylinder can be slid and rotated upon the inner one and hence with the correct sequence of movements, multiplications and divisions can be made and the answers read off the two pointers which project over the cylindrical scale.FULLER CALCULATOR inscribed on brass pointerscientific instrument, mathematics, calculating
