The item is painted yellow and green but the paint is well rusted and peeling in places. ...This set of baby scales is believed to have been used in a Baby Health Centre in Warrnambool. The first Baby Health Centre in Warrnambool was opened in Liebig Street in October 1921. It was initially run by Sister Riley. The development of Baby Health Centres in Victoria was largely due to the work of Dr Isabella Younger-Ross (1887-1956). She was born in Warrnambool to Henrietta and John Younger (the Younger department store operated in Liebig Street Warrnambool for over 60 years). Isabella Younger Ross studied medicine in Melbourne and Glasgow and she was a prominent worker in the field of maternal and infant welfare for over 40 years. These scales are retained as an example of the type of equipment used in baby health centres in the early to mid 20th century. It will be useful for display.This is a metal set of scales with a rectangular base tapering at one end. At the top is attached a metal receptacle for holding a baby and underneath this on top of the base is the scale mechanism with a metal measuring device.

It was designed and introduced in 1620 by English clergyman and mathematician Edmund Gunter (1581–1626). It enabled plots of land to be accurately surveyed and plotted, for legal and commercial purposes. The provenance of this particular Gunter Chain is unknown but it is believed to be used either by the City of Bendigo / Sandhurst or the Lands Department locally when measuring and laying out plots and streets locally. A 66-foot (20.1 m) chain divided into 100 links, marked off into groups of 10 by brass rings or tags. Each link is 7.92 inches (201 mm) long. A quarter chain, or 25 links, measures 16 feet 6 inches (5.03 m) also called a a rod (or pole) measure. Ten chains measure a furlong and 80 chains measure a statute mile. city of greater bendigo surveying -

It was not until 1891 that the efforts to sewer Melbourne came to fruition with the setting up of the Melbourne Metropolitan Board of Works (MMBW), now known as Melbourne Water. From 1891 until 1992, it was the responsibility of the MMBW to safeguard public health by providing a sewerage system and a safe water supply system. In 1992, The MMBW merged with a number of smaller urban water authorities to form Melbourne Water. This item was used by MMBW employees as a measuring device to determine areas or figures on a plane surface having either straight or irregular boundaries. The Compensating Polar Planimeter is of historical significance for its association with the former Melbourne and Metropolitan Board of Works (MMBW). This measuring device is perfectly intact and a rare surviving object of standard Board issued equipment. The kit is significant for its representativeness of the theme of Technology in building Victoria's industries and workforce, which continues to resonate strongly within Melbourne Water today.The instrument is inside a black metal case with accessories including: Setting bar, screwdriver, Allen key and spare pole point. Inside is also the adjustable planimeter. mmbw, melbourne water, melbourne metropolitan board of works, technology, instrument, work, measure, historic, water, staff -

Historical examples are rare. There are less than one hundred known to exist and most of these have been recovered from shipwrecks, many from Spanish and Portuguese vessels. An astrolabe is a measuring device once used to navigate the seas by observing the sun and stars to measure their altitude. The measurement of altitude could then be used to calculate the ship’s latitude but at that time in history there was no means of measuring longitude. The body of the navigational astrolabe was cast brass and much heavier, and less complicated than the variety used on land. The heavier weight and cut-away shape reduced the effect of the wind and waves when trying to use it at sea. A mariner’s astrolabe or ‘star finder’ is a simplified version than that used by Arabic astronomers to find the altitude of the sun and stars above the horizon, and time of the sunrise and sunset. It is a forerunner to the quadrant, octant and sextant and was popular for about 200 years over the 1500s and 1600s to find the latitude of a ship at sea. The user held the astrolabe at eye level and, usually with assistance, aligned the stars through the two small sights (pinnules), then read the altitude indicated by the pointer on the arm. It could also be used to sight the sun by holding it lower down, aiming it at the sun, and adjusting it until the sun shone through both pinnules. This astrolabe is an example used to demonstrate the mariner’s astrolabe, which was navigational tool of the 1500s and 1600s, in the time before longitude was able to be determined. It is a forerunner to modern navigation technology. Mariner’s astrolabe – a representative example. A gold painted, disc shaped object with cut outs and revolving arm in centre. The arm has two sights attached at right angles. The top has a ring attached.

The sphygmomanometer was considered cumbersome and the Dudgeon sphygmograph was smaller, and once placed into its box, could be carried in a pocket. The Dudgeon sphygmograph was introduced in 1881. It was strapped tot he wrist with a metal strip that moved a stylus. This transmitted a record of the pulse onto smoked paper, creating a record of blood pressure.The sphygmograph is housed in a purple-lined, leather bound case with a metal hinge and clasp located halfway up the case. It is constructed from chrome and comprises several moving parts including wires, knobs and handles.

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 ease of use of spring scales over balance scales. One of the most common types of spring scales was the kitchen scale also known as a family or dial scale. Designed for horizontal surfaces, these vintage kitchen scales used the weight of goods in a pan at the top of the scale to force the spring down rather than the balance system. Such scales were common in early 20th century households and were sold by many companies. Many had flat weighing surfaces but some were topped by shallow pans. Companies such as Salters, Chatillon, and Fairbanks were the most popular brands used. These scales are significant as they identify one of the basic preparation items for the weighing of foodstuff in the family kitchen to prepare everyday meals.

By the 17th century usage and legal statute had established the acre, rod, and furlong at their present values together with other historic units such as the peck. Establishment of the System: The Weights and Measures ...The peck has been in use since the early 14th century when it was introduced as a measure for flour. The term referred to varying quantities until the modern units of measurement were defined in the 19th century. Cities in England used to have official standard weights and measures for that city or area. These containers were marked with the city's name and emblem, merchant’s weights and measures would then be checked against this to make sure they weren't trying to cheat their customers. The item in the collection is a standard measure approved by Bristol City and used by that City’s grocers to measure dry goods such as peas, beans, sugar, flour, meal etc., and its metal banding ensures that the measure cannot be reduced in size to cheat customers. Additional Information: The British Imperial System evolved from the thousands of Roman, Celtic, Anglo-Saxon, and customary local units employed in the middle Ages. Traditional names such as pound, foot, and gallon were widely used, but the values so designated varied with time, place, trade, product specifications, and dozens of other requirements. Early royal standards were established to enforce uniformity took the name Winchester, after the ancient tenth century capital of Britain. King Henry VII reaffirmed the customary Winchester standards for capacity and length and distributed royal standards throughout the realm. This process was repeated about a century later in the reign of Queen Elizabeth I. In the 16th century, the rod (5.5 yards, or 16.5 feet) was defined (once again as a learning device and not as a standard) defined by the length of the left feet of 16 men lined up heel to toe as they emerged from the church. By the 17th century usage and legal statute had established the acre, rod, and furlong at their present values together with other historic units such as the peck. Establishment of the System: The Weights and Measures Act of 1824 and the Act of 1878 established the British Imperial System based on precise definitions of selected existing units. The 1824 act sanctioned a single imperial gallon to replace the wine, ale, and corn (wheat) gallons that were in general use. The new gallon was defined as equal in volume to 10 pounds avoirdupois of distilled water weighed at 62°F with the barometer at 30 inches, or 277.274 cubic inches (later corrected to 277.421 cubic inches). The two new basic standard units were the imperial standard yard and the troy pound, which was later restricted to weighing drugs, precious metals, and jewels. In 1963 an act of parliament abolished archaic measures as the rod and chaldron and a metric system was adopted. An early example of a dry measuring container giving a snapshot of how imperial weights and measures developed in England to evolve the British measurement system into the metric arrangement that most countries have adopted today including Australia.

He and his nephews John & George, founded the firm of George Salter & Co., still notable makers of scales and balances, who in 1838 patented the spring balance. They also applied the same spring balance principle to steam locomotive safety valves, replacing the earlier deadweight valves. https://en.wikipedia.org/wiki/Spring_scale Today, spring scales are very popular with recreational fishers. The ability to weigh things reasonably accurately with a small inexpensive apparatus allowed for the exact weight of items to be ascertained.

Flagstaff Hill Maritime Museum and VillageInstrument - Clock, 1900's
... In the 1950’s they were producing meters and high grade measuring equipment but by the 1970's the business had closed and the factory was demolished in the mid-1980 "s The item is a good example of the later use of an early mechanism “Fusee” that was originally invented around 1525 in Prague. This type of clock mechanism was replaced as watchmakers looked for mechanisms that could reduce the size of clocks and watches, it appears England was the only country to continue making clocks with a Fusee device until around 1900,s of which our clock is an example. ...In August 1884, Alfred Hirst who had started his trade as a watch repairer and was described as a watchmaker extraordinaire established Hirst Brothers and Company, on Union Street in Oldham Manchester. He took his two stepbrothers into the business and the company was set up to produce timepieces and jewellery as well as importing “Limit company” Swiss watches and precision machine tools for the watch and clock trade. By 1902 Hirst Brothers. had become a limited company and was still growing, adding other businesses in Manchester in 1904 and at Birmingham in 1907. The quality of the clocks and watches was such that Alfred Hirst realised his greatest ambition in 1912 with a range of watches which carried the "Limit" trademark. These watch movements had originally been made in Switzerland and shipped to Hirst Bros. to be put into British made “Dennison” cases. This trade brought even more growth with additional sales offices opening in London and Glasgow. At the outbreak of the First World War in 1914 found them manufacturing aircraft parts including revolution counters and optical instruments. The firm had been tasked by the Ministry of Munitions to solve the problem of pilots dropping bombs by hand and as a result, they effectively created the first bomb rack. After the war, the company once again began to prosper and with the demand for their products increasing they looked to build a new purpose-built factory to manufacture their products. In 1917 they purchased a seven-acre field site at Tame Side Dobcross, the designing of the new factory was passed onto local architect AJ Howcroft. His brief for the design of the clockworks would have been prompted by Alfred Hirst who having visited modern factories in the United States was inspired by the latest factory designs providing as much daylight as possible during working hours. The factory was eventually completed in 1920, by the mid-1920s there were cheap clock imports from Germany and production turned to radio sets and other components as well as counter and gas meters for the "Parkinson and Cowan" company who was later to take over the business. In 1926 came the cotton crash and the District Bank who had loans with the company foreclosed on the Hirst loan. The company did survive and throughout the second World, War II were involved in munitions work at the factory as well as making instruments for various aircraft. In the 1950’s they were producing meters and high grade measuring equipment but by the 1970's the business had closed and the factory was demolished in the mid-1980 "s The item is a good example of the later use of an early mechanism “Fusee” that was originally invented around 1525 in Prague. This type of clock mechanism was replaced as watchmakers looked for mechanisms that could reduce the size of clocks and watches, it appears England was the only country to continue making clocks with a Fusee device until around 1900,s of which our clock is an example. The use of a Fusee movement eventually became obsolete in 1970,s. The item is significant for the collection as it is a clock with a movement that has long since been made obsolete.

... Flagstaff Hill Warrnambool Shipwrecked-coast Flagstaff-Hill Flagstaff-Hill-Maritime-Museum Maritime-Museum Shipwreck-coast Flagstaff-Hill-Maritime-Village Measuring device Measuring cylinder Glass Glass tube or cylinder with wide base and pouring lip. ...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. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery.Glass tube or cylinder with wide base and pouring lip.

The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting.
