A graduated cylinder, also known as a measuring cylinder or mixing cylinder, is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured. A traditional graduated cylinder is usually narrow and tall so as to increase the accuracy and precision of volume measurement. It has a plastic or glass base (stand, foot, support) and a "spout" for easy pouring of the measured liquid. https://en.wikipedia.org/wiki/Graduated_cylinder The glass measuring tube was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) According to Berry, her mother Gladys made a lot of their clothes. She was very talented and did some lovely embroidery including lingerie for her trousseau and beautifully handmade baby clothes. Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . Its first station was in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill and purchased a share of the Nelson Street practice and Mira hospital (a 2 bed ward at the Nelson Street Practice) from Dr Les Middleton one of the Middleton Brothers, the current owners of what previously once Dr Tom Ryan’s practice. Dr Tom and his brother had worked as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He had been House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan had gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. 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. His practitioner’s plate from his Nhill surgery is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. When Dr Angus took up practice in the Dr Edward and Dr Tom Ryan’s old premises he obtained their extensive collection of historical medical equipment and materials spanning 1884-1926. A large part of this collection is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. and an ALDI sore is on the land that was once their tennis court). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served with the Australian Department of Defence as a Surgeon Captain during WWII 1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the 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 in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. He had an interest in people and the community They were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”. The W.R. Angus Collection is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being an historical example of medicine from late 19th to mid-20th century.

This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo. The JGEM vehicle was extensively used by RA Svy within Australia from the late 1960s. A limited number of Ground Elevation Meter (GEM) station wagon type vehicles were manufactured by General Motors Corporation (GMC) in the USA for the United States Geological Survey, Canada’s mapping agencies, RA Svy and National Mapping (Natmap). The GEM was a four-wheel drive, four-wheel steer vehicle. Four-wheel steering was necessary to avoid systematic errors caused by non-tracking of front and rear wheels on conventionally steered vehicles. The manufacturer substituted the rear axle with a front axle and connected them to form the four-wheel steering mechanism. The two Australian GEM vehicles, referred to as Johnson GEMs (JGEMs) were converted into right-hand drive. After delivery in 1964, acceptance Natmap and RA Svy testing and operator training was undertaken at the Army's School of Military Survey located at Balcombe, Victoria. A small fifth wheel was mounted on a cantilever arm suspension midway between the front and rear wheels on the right side of the vehicle. It was lowered to and raised from its operating position by use of a constant pressure air cylinder. A telescopic bar, suspended between the front and rear axles, provided the reference datum for the angle measurement. The wheel provided the velocity or distance signal through a pulse generator system. A sensitive pendulum mounted on this bar provided the angle measurement for each minute distance traversed. The JGEM contained electromechanical instruments used to determine relative elevations, by trigonometric principles, along a traversed path. These relative elevations were obtained through apparatus which measures the instantaneous angle of inclination of the road and the instantaneous velocity of the meter along such a path. Road routes over which the JGEM operated were planned so that each started and ended as near as practicable to an existing point of known elevation (formally referred to as a level traverse bench mark). The difference in height from the bench mark and the road surface alongside the JGEM’s fifth wheel was measured with a level and staff. Along each route, mapping control photo reference points where new elevation values were required were identified on aerial photographs. Under favourable conditions it was possible to survey as much as 160km in an ordinary working day. The first of RA Svy’s JGEM operations was undertaken in 1:250,000 scale map areas of Queensland. CPL John Hook was the JGEM’s main operator in the early 1970s undertaking operations covering 1:250,000 scale map blocks over northern Victoria and central NSW, each requiring 36 points (9 runs of photography and 4 points across. SPR Lyn Thompson and SPR Bob McDonagh teamed with CPL Hook on some of these JGEM operations. When RA Svy was integrated into the Royal Australian Engineers in 1996, the JGEM vehicle with the Survey Corps collection was donated to its museum. It is believed to be the last of the original manufactured fleet in existence. The JGEM has undergone extensive refurbishment to achieve roadworthiness and is currently housed at The Australian Army Museum of Military Engineering, Hoslworthy Barracks, NSW. It can be viewed by making an appointment with the museum’s curator.This is a set of 16 photograph of the Royal Australian Survey Corps’ Johnson Ground Elevation Meter (JGEM) Survey Vehicle taken at the Army Survey Regiment, Fortuna, Bendigo.

Joseph Sheard sat for a mensuration exam at the Bendigo School of Mines, in 1908, achieving a 67 percent mark. Mensuration is a branch of mathematics that focuses on measuring geometric figures. It involves calculating attributes such as area, volume, and perimeter for both 2D (plane) shapes and 3D (solid) objects. Key concepts in mensuration include formulas for calculating the area of shapes like squares and circles, as well as the volume of solids like cubes and cylinders. Additionally, mensuration is often applied in practical scenarios, such as architecture and engineering, to determine material requirements and space utilization.Hand drawn design in black pen, on light tan paper.

This container is a pre-Decimal, Imperial Standard Half Bushel, part of a three-piece set of Standard measures used in Victoria from around 1900 to 1940. The measures were made in Melbourne by J. McEwan & Co. These three measures were likely used by the local Melbourne authority that monitored weights and measures in the mid to late 19th century. . An Imperial Bushel was equal to 8 gallons, or 36.36872 litres . An Imperial Peck equals a quarter of a Bushel, or 9.09 litres Standards for weights and measures began in Victoria when the Melbourne Observatory received primary sets of Imperial Standard Weights and Measures from Britain. These were tested against the then British Imperial Standards to measure length, weight and currency. Administrative bodies in the Colony of Australia could then compare their weights and measures against these British Primary Standards and adjust their Measures accordingly, to maintain the Standards. The Weights and Measures Act of 1862 was passed in Victoria, and local inspectors were established throughout the colony. By the 1870s, local councils and shires in Victoria held a set of Standards used to test scales, weights, and measures used by manufacturers, wholesalers, and retailers. Every ten years, the councils’ Standards needed to be rechecked against the Victorian Standards. In the 19th Century, the Victorian Customs Department inspected and maintained the Standards. In 1901, the Customs Department was transferred to the Federal Government, but the Weights and Measures authority remained with the Victorian Government and relocated to the Melbourne Observatory. In 1904, the Standard weights and measures, and testing equipment, were installed in the room of a new building erected at the south end of the Great Melbourne Telescope House. The room became known as the Whirling Room, due to its large whirling apparatus that tested air meters. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue maintaining the Standards. On February 14th, 1966, Australia began its conversion to metric measures and currency, and a new set of Standard Measures was introduced; the conversion took place in stages. The Weights and Measures Branch remained at the Observatory site until 1995. James McEwan & Co.: - The maker of this set of Standard Measures was James McEwan. His Melbourne business was established in 1852 and sold retail furniture and wholesale ironmongery. The firm’s warehouses were situated at the intersection of 81-83 Elizabeth and Little Collins Streets. Shortly afterwards, the firm partnered with William Kerr Thomson and Samuel Renwick. When McEwan died in 1868, his partners carried on and expanded the business under his name, J McEwan. 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; agricultural equipment, building materials, mining items, steam engines, tools of all types and marble fireplaces. 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. It also serviced the Mauritius islands and the Pacific area with its steamship, the Suva, and a brig, the Shannon.The set of Imperial Standard Measures is an example of a bronze measure container made specifically for J. McEwan & Co. Today, it helps us to understand 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 McEwan, and used by Victoria’s authorities legally responsible for ensuring that dry goods sold in Victoria by wholesalers and retailers are correct.Imperial Standard Measure: a container to measure the volume of a Half Bushel. It is part of a set of three precision measures - a Peck, a Half Bushel and a Bushel – used by government authorities in Victoria.

Scales such as the subject item were used in a domestic situation. Salter has been a name long associated with weights and measures especially in the home kitchen. The firm began life in the late 1760s in the village of Bilston, England when Richard Salter, a spring maker, began making the first spring scales in Britain. He called these scales "pocket steelyards", though they work on a different principle from steelyard balances. By 1825 his nephew George had taken over the company, which became known as George Salter & Co. George later established a manufacturing site in the town of West Bromwich, about 4 miles (7 km) from Bilston. West Bromwich Albion football club was formed from workers at this works site. From here the company produced a wide variety of scales including the UK's first bathroom scales. Other items were added to the range, including irons, mincers, potato chippers, coin-operated machines and the first typewriters made in the UK. The business thrived throughout the 1900s, and by 1950 it employed over 2000 people, still in the same area and owned by the same family.Salter is a British housewares brand developing products that span a wide range of core product categories, including scales, electrical, cookware. It is a market leader in kitchen and bathroom scales and one of the UK’s oldest consumer brands.  Established in 1760, Salter has been developing precision products for over 260 years. It was acquired by Manchester-based consumer goods giant Ultimate Products in 2021 after they had previously licensed the brand for cookware and kitchen electrical since 2011."Scale Salter's Spring Balance brass cylinder with ring at one end and a hook at the otherSalter trademark stamped on front.

This scale was owned by Dr Angus, whose training and experience included chemistry and pharmacy. This is a sliding balance scale. The object to be weighed, such as a letter or a dose of medicine, is placed on the square metal plate and the weight, the slider, is moved along the notched metal arm and adjusted until the arm is horizontal, then reading is recorded of the figure the pointer on the slider is positioned. This design of small is often referred to as a letter scale. This item was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969.The scale is significant as an example of 20th century measuring and weighing equipment. It is also important for its association with the W.R. Angus Collection, which is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being a historical example of medicine, administration, household equipment and clothing from the late 19th to the mid-20th centuries. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery. Scale; a small sliding balance letter scale. The scale has a flat metal platform and a toothed metal balance arm with cylindrical brass weight. These are attached to a decorative metal stand that is mounted onto a shaped lacquered black wooden base. The sliding weight causes the arm to pivot on the stand. The arm is marked into equal-length segments from 0 to 8. Each segment is marked into halves. There is no maker’s mark. The scale is part of the W.R.

This container is a pre-Decimal, Imperial Standard Peck, part of a three-piece set of Standard measures used in Victoria from around 1900 to 1940. The measures were made in Melbourne by J. McEwan & Co. These three measures were likely used by the local Melbourne authority that monitored weights and measures in the mid to late 19th century. . An Imperial Bushel was equal to 8 gallons, or 36.36872 litres . An Imperial Peck equals a quarter of a Bushel, or 9.09 litres Standards for weights and measures began in Victoria when the Melbourne Observatory received primary sets of Imperial Standard Weights and Measures from Britain. These were tested against the then British Imperial Standards to measure length, weight and currency. Administrative bodies in the Colony of Australia could then compare their weights and measures against these British Primary Standards and adjust their Measures accordingly, to maintain the Standards. The Weights and Measures Act of 1862 was passed in Victoria, and local inspectors were established throughout the colony. By the 1870s, local councils and shires in Victoria held a set of Standards used to test scales, weights, and measures used by manufacturers, wholesalers, and retailers. Every ten years, the councils’ Standards needed to be rechecked against the Victorian Standards. In the 19th Century, the Victorian Customs Department inspected and maintained the Standards. In 1901, the Customs Department was transferred to the Federal Government, but the Weights and Measures authority remained with the Victorian Government and relocated to the Melbourne Observatory. In 1904, the Standard weights and measures, and testing equipment, were installed in the room of a new building erected at the south end of the Great Melbourne Telescope House. The room became known as the Whirling Room, due to its large whirling apparatus that tested air meters. When the Melbourne Observatory closed in 1944, the Weights and Measures Branch was formed to continue maintaining the Standards. On February 14th, 1966, Australia began its conversion to metric measures and currency, and a new set of Standard Measures was introduced; the conversion took place in stages. The Weights and Measures Branch remained at the Observatory site until 1995. James McEwan & Co.: - The maker of this set of Standard Measures was James McEwan. His Melbourne business was established in 1852 and sold retail furniture and wholesale ironmongery. The firm’s warehouses were situated at the intersection of 81-83 Elizabeth and Little Collins Streets. Shortly afterwards, the firm partnered with William Kerr Thomson and Samuel Renwick. When McEwan died in 1868, his partners carried on and expanded the business under his name, J McEwan. 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; agricultural equipment, building materials, mining items, steam engines, tools of all types and marble fireplaces. 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. It also serviced the Mauritius islands and the Pacific area with its steamship, the Suva, and a brig, the Shannon. The set of Imperial Standard Measures is an example of a bronze measure container made specifically for J. McEwan & Co. Today, it helps us to understand 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 McEwan, and used by Victoria’s authorities legally responsible for ensuring that dry goods sold in Victoria by wholesalers and retailers are correct.

Optometrists are trained to examine eyes and prescribe visual aids such as spectacles. The optometer pictured in the media section of this document dates from the 1800s. The optometer was used with various lenses to determine the refraction of the eye. Refraction means the extent to which light is bent by an individual's eye. The result can determine how short-sighted or long-sighted they are, and the strength of spectacles required. In the second half of the 1800s, ophthalmologists also devised instruments to measure the separate components of vision. Dr Jules Badal developed the pictured instrument in 1876. It was based on an optometer invented by William Porterfield in 1759. The brass stands look as though they were made for an optometer to be table mounted, with heavy brass stands and designed to hold a cylindrical object securely as would be required by an optometer. Stands appear to have been very well made and very early probably early to mid 19th Century by a well known scientific instrument maker given there are no inscriptions or marks to indicate the time period made or maker it is difficult to assume significance to these items at this point in time as well as the items are incomplete.The brass stands believed to be for mounting an early Optometer an (ophthalmic instrument) Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, stands for scientific instrument

From Scarborough Maritime Heritage Centre: A Yacht Log was a nautical instrument for measuring a vessel's speed and distance travelled. When navigating a ship it is essential to be able to estimate the boat's speed and distance travelled to determine its position at sea. In times past the only way to measure a ship's speed was to throw a wood log into the water and observe how fast it moved away from the ship. In the 16th century, the log was fastened to a rope knotted at set intervals. The log was thrown over the stern (back) of the vessel and a crew member counted the number of knots that were paid out in a set time. From this they could estimate the speed of the vessel through the water. This was known as streaming the log and is also the derivation of the knot as a measurement of nautical speed. In 1878, Thomas Ferdinand Walker (1837–1921), an engineer in Birmingham, patented a mechanical log in which a recording instrument was attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. The 'Log' at the Heritage Centre was recovered from a skip in Scarborough and was one of the first artefacts collected by the volunteer group. It is made of brass with a ceramic dial, with the main scale marked from 0 to 100 nautical miles and an inset dial marked from 0 to 10 miles. It has a fixing plate, on which it can turn, with which it would have been attached to the 'taffrail', the rail at the stern of a ship, usually on the starboard side. The Walker’s Excelsior Mark IV instrument was designed for smaller vessels, such as yachts, launches and fishing vessels. Its exact date of manufacture cannot be determined but this design was manufactured in the first half of the 20th century. These mechanical logs have now been superseded by electronic equipment such as GPS navigation instruments.This instrument was made by a significant nautical instrument manufacturer and demonstrates the innovation needed at the time for improved navigation and safety at sea.Timber Box containing an instrument for measuring speed and distance. There is a brass, cased log with a white enamel dial. It also includes a towing cord and cylindrical rotator. The box has paper labelling on the front and also the inside of the lid. The label on the inside of the lid has instructions for use. Although the lid is hinged it has broken off and is separate. The hinges remain attached.Enamel Dial: Walkers Patent Excelsior Yacht Logmaritime, maritime history, tool, navigational tool, navigational instrument, navigation, sailing, walkers, maritime technology, walker & son

How widely the prisoptometer was used is unclear but the Standard Optical Company later patented a new model, The Standard Prisoptometer, on June 21, 1904. Edward Jackson's crossed cylinder technique of determining astigmatism was first detailed in the Transactions of the American Ophthalmological Society (1887)4:595-598. The convenience of Jackson's crossed cylinder lenses over the prisoptometer in weight, cost, portability and reliability meant that they were soon almost universally adopted.This is a rare item as few are known world wide.This instrument is an optometer, that is, a device to measure the refractive error of an eye. It is made of cast iron, steel, brass and glass. It contains a prism which could be rotated, and was used to view a disc or an object circle. The prism caused monocular doubling of the object circle and the separation of the two images varied as the prism rotated, depending on the astigmatism present. The axis of the astigmatism was indicated by the prisoptometer and trial lenses were used to determine the the magnitude of the spherical and cylindrical refractive errorImprinted:"DR CULBERTSON'S PRISOPTOMETER/ GENEVA OPTICAL COMPANY MAKERS, GENEVA, N.Y./ PATENTED SEPT, 21, 1886".

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.

Thomas Walker & Son was internationally renowned in the manufacturing of ships logs. Founding father Thomas Walker (1805–1871), an engineer in Birmingham, patented a mechanical log in 1878 which was a recording instrument that attached to a rail at the stern of a vessel connected by a long cord with a rotor which was towed behind the ship. The instrument dial recorded the distance travelled. Thomas Walker first went into business to manufacture stoves at 58 Oxford Street Birmingham. Walker’s self-feeding stove was widely lauded at the Paris Exhibition of 1855, winning a prize medal and kick starting the first of many notable innovations for the Walker family's manufacturing business. However, it wasn’t until working on an earlier ships log model invented by his Uncle that Thomas Walker became interested in the further development of this device, used to ascertain a ship’s speed. Walker continued to improve on the common log for the company of Massey & Sons and these improvements were deemed revolutionary. This log became a firm favourite of the West India Association (British-based organisation promoting ties and trade with the British Caribbean) and the most common log in use for two generations. It took till 1861 for Thomas Walker and his son, Thomas Ferdinand Walker (1831-1921) to patent the first Walker log of many. Together, with the introduction of the A1 Harpoon Log two years later, they established the Walker Log Business as a force to be reckoned with. By the time of his passing in 1871, Thomas Walker Snr had not only founded a family business with considerable staying power but also instilled a tradition of public service. Having sat as a representative on the Birmingham Town Council for 15 years and played an active role in public works, he was soon given the nickname of ‘Blue Brick Walker’. Much like his father, Thomas Ferdinand Walker changed the face of the maritime industry. His patent of 1897, the ‘Cherub’ log, was a notable departure from the past providing a far more accurate reading and replacing the majority of logs of the age. They were the first to produce an electric log and the Walker factory was one of the first to introduce the 48 hour work week for employees. This ship log was invented and made by a significant marine instrument maker and innovator of machinery. It demonstrates the huge leap taken to improve navigational accuracy at sea with an instrument that was in use for decades. Ship Log, three analogue dials calibrated in increments of Miles, the Rocket Log is a nautical instrument for measuring a vessel’s speed and distance traveled. The floating log was drawn behind the ship over a fixed time period in order to measure the distance traveled. The counter could measure enough miles to cover the maximum distance traveled by a ship in one day. The log has two distinct parts; a brass register, made by Walker, showing the distance recorded and the rotator made by Reynolds, that spins in the water driving the counter. both parts are connected by a linked chain. The register has a cylindrical brass body approx 4.5 cm diameter containing registering mechanism with hardened steel bearings. Distance is indicated by the three pointers on enamel plate as follows: graduated every 10 miles from 0-100; every mile from 1-10; every 1/4 mile from 1/4 -1. A brass sling and eye secured to the body enables it to be attached to the taffrail. The original rotator would have had a cylindrical tapered wooden body, approx 4.5 cm in diameter with three metal alloy fins or could be all made from brass. A towing eye is fitted to the tapered end. The two pieces of apparatus are connected by a length of linked chain, length 22.9 cm."Walkers Rocket Ship-Log Birmingham (Patented)" printed on face-plate.
