J. Mann and Sons was first established as a farm produce store in 1921. The range of products was extended in the 1930s and included groceries and hardware, as well as the first petrol bowser in Wodonga outside the store. After WWII, the premises were extended and the range of products continued to increase. In the 1960s the Mann Family opened a new supermarket in Wodonga, in addition to the hardware business, providing steel, plumbing and industrial supplies, and they employed over 100 people at one stage. With changes in the retail industry, the Mann Family sold the main hardware business to Bunnings and the produce business to the Kelly brothers in 2006. Mercury Scales was founded in Thebarton, South Australia in 1946. The business experienced rapid growth, leading to its joining with A&D’s global organisation and evolving into A&D Mercury. IN 2023 A&D Weighing is an Australian leader in the supply of electronic weighing scales, balances, metal detectors, checkweighers and weighing systems. This model was approved on 13 February 1980.

These are sales photographs for William Tatham Ltd. of Rochdale. These photographs are taken in the fitting shop at William Tatham Ltd. where final assembly would have taken place. The Automatic Feeding Machine automatically dispenses wool to a carding machine, so that an even, constant supply is received. This eliminated the manual labour previously needed for the initial weighing and feeding of wool. The photographed machine was made by William Tatham Ltd, a textile engineering company based in Rochdale, UK. Established in 1866, Tatham developed innovative textile machinery and sent their products to Australia and other countries around the world.Two black and white photos of an Automatic Feeding Machine in a landscape format.

A barometer is an instrument used for measuring atmosphere pressure thus determining weather changes.The first apparatus generally accepted as a barometer was that set up in Florence in 1644 by Evangelista Torricelli (1608–1647), a mathematician and physicist. Torricelli filled a glass tube with mercury, sealed it at one end, and inverted it with its open end in a dish of mercury. The level always fell a short way down the tube, then settled at a height of about thirty inches. He concluded correctly that the mercury column was sustained by the weight of the air pressing on the open surface of mercury, and further experiments convinced him that the space above the mercury in the tube was a vacuum. He noted that the level rose and fell with changing temperature, but he was unable to use his apparatus to measure variations in the weight of the atmosphere because he had not foreseen that temperature would affect the level of the mercury. News of this experiment circulated quickly among European scientists, who hastened to replicate the experiment. Torricelli's conclusions were not universally accepted because some disputed whether the air had weight, while both Aristotle and the Catholic Church denied the possibility of a vacuum. In France, the philosopher René Descartes (1596–1650) seems to have been the first person, probably in 1647, to attach a graduated scale to the tube so that he could record any changes attributable to the weather. At around this time Duke Ferdinand II of Tuscany organized the first short-lived meteorological network among scientists in other Italian cities, gathering observations of pressure, temperature, humidity, wind direction, and state of the sky.Theis barometer is an example of a household item from the early 20th century, used to determine the day's weather. The barometer is significant as an aid to human social, material and scientific development.Barometer, round, brass housing inset into carved wooden casing (lacquer mostly worn off).

The Thermoscope The thermometer dates back to the early 1600s, with Galileo’s invention of the “thermoscope.” Galileo’s device could determine whether temperature was rising or falling, but was not able to detect the actual scale of the temperature. In 1612, Italian inventor and physician Sanctorius was the first to put a numerical scale on the thermoscope. His product was also designed for taking temperature from a patient’s mouth. However, neither Galileo’s nor Sanctorius’ thermoscopes were very accurate. Standardized Scales In 1709, Daniel Gabriel Fahrenheit invented his first thermometer using alcohol. He later introduced the mercury thermometer in 1714, which was more accurate and predictable. The Fahrenheit temperature scale was standardized in 1724 with a freezing point of 32 degrees and a boiling point of 212 degrees. Fahrenheit’s mercury thermometer is recognized as the first modern thermometer with a standardized scale. The Celsius scale was invented in 1742 by Anders Celsius, with a freezing point of 0 degrees and a boiling point of 100 degrees. This scale was accepted into the international conference on weights and measurements in 1948. The Kelvin Scale, measuring extreme temperatures, was developed by Lord Kelvin in 1848. Registering Thermometers Early versions of the thermometer were not able to hold the temperature after they were moved. You can imagine how this made it hard for doctors to correctly read a patient’s temperature. The first thermometer that could register and hold onto temperature was built by James Six in 1782. Today, it is known as Six’s thermometer. Since then, the mercury thermometer was adapted to read a patients temperature after leaving the body. Registering thermometers are still used today and are reset by shaking down the mercury to the bottom of the tube. The Modern Devices Modern Day Thermometers This brings us to the first practical clinical thermometer, which was invented in 1867 by Sir Thomas Allbutt. The device was portable, about 6 inches long and was capable of recording a patient’s temperature in 5 minutes. Now, there are a few options for clinical and home use. Liquid filled thermometers have been adapted based on the designs of inventors like Fahrenheight and Six are still used today. Digital thermometers, like the Omron Compact Digital Thermometer, are capable of finding a temperature and producing an electronic number within a minute of use. Digital ear thermometers also produce a quick and accurate temperature. Dr. Jacob Fraden invented an infared thermometer called the Thermoscan Human Ear Thermometer in 1984. These thermometers use an infared light to scan the heat radiation in a patient’s ear or forehead. The thermometer, like many medical devices, has made strides in efficiency and accuracy. As medical technology continues to advance, businesses in the medical device industry must be prepared to move with it. This thermometer 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. 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 the 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 a physician, surgeon, and chemist. In 1926, he was appointed as a 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 would take time to 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 Australian Commonwealth Line’s SS 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 ) Dr. Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928. The organisation began in South Australia through the Presbyterian Church that year, with its first station being 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 a surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr. Angus returned to Nhill where he’d previously worked as Medical Assistant and purchased a share of the Nelson Street practice and Mira hospital from Dr. Les Middleton one of the Middleton Brothers, the current owners of what was once Dr. Tom Ryan’s practice. Dr. L Middleton was House Surgeon at the Nhill Hospital from 1926-1933 when he resigned. [Dr. Tom Ryan’s practice had originally belonged to his older brother Dr. Edward Ryan, who came to Nhill in 1885. Dr. Edward saw patients in his rooms, firstly in Victoria Street and in 1886 in Nelson Street, until 1901. The Nelson Street practice also had a 2-bed ward, called Mira Private Hospital ). Dr. Edward Ryan was House Surgeon at the Nhill Hospital from 1884-1902. He also had occasions where he successfully performed veterinary surgery for the local farmers too. Dr. Tom Ryan then purchased the practice from his brother in 1901. Both Dr. Edward and Dr. Tom Ryan work as surgeons including in eye surgery. Dr. Tom Ryan performed many of his operations in the Mira private hospital on his premises. He too was House Surgeon at the Nhill Hospital from 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 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. Dr. Tom Ryan moved from Nhill in 1926. He became a Fellow of the Royal Australasian College of Surgeons in 1927, soon after its formation, a rare accolade for a doctor outside any of the major cities. He remained a bachelor and died suddenly on 7th Dec 1955, aged 91, at his home in Ararat. Scholarships and prizes are still awarded to medical students in the honour of Dr. T.F. Ryan and his father, Dr. Michael Ryan, and brother, John Patrick Ryan. ] When Dr. Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon from 1933-1938. His practitioner’s plate from his Nhill surgery states “HOURS Daily, except Tuesdays, Fridays and Saturday afternoons, 9-10 am, 2-4 pm, 7-8 pm. Sundays by appointment”. This plate is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. Dr. Edward Ryan and Dr. Tom Ryan had an extensive collection of historical medical equipment and materials spanning 1884-1926 and when Dr. Angus took up practice in their old premises he obtained this collection, a large part of which is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. During his time in Nhill Dr. Angus was involved in the merging of the Mira Hospital and Nhill Public Hospital into one public hospital and the property titles were passed on to Nhill Hospital in 1939. 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. ). 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 silkworm 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. (The duties of a Port Medical Officer were outlined by the Colonial Secretary on 21st June 1839 under the terms of the Quarantine Act. 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 a surgeon at the Warrnambool Base Hospital from 1939-1942, He served as a Surgeon Captain during WWII1942-45, 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 artificial eye improvements. He was Honorary Consultant Ophthalmologist at 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 a 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 eyewitness from the late 1880s 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. Their interests included organisations such as the Red Cross, Rostrum, Warrnambool and District Historical Society (founding members), Wine and Food Society, Steering Committee for Tertiary Education in Warrnambool, Local National Trust, Good Neighbour Council, Housing Commission Advisory Board, United Services Institute, Legion of Ex-Servicemen, Olympic Pool Committee, Food for Britain Organisation, Warrnambool Hospital, Anti-Cancer Council, Boys’ Club, Charitable Council, National Fitness Council, and Air Raid Precautions Group. He was also a member of the Steam Preservation Society and derived much pleasure from a steam traction engine on his farm. He had an interest in people and the community He and his wife Gladys 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.

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

This Sike’s Hydrometer was donated by the Port Fairy Customs Office as it was no longer required by them due to a change in the law. The hydrometer was part of a system for Ullaging or calculating the amount of liquid remaining in a container of liquor such as a barrel, and the amount of alcoholic content in the contents. It can also measure the free space or head space remaining. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid.The Sikes hydrometer is of local significance because of its association with the Government's Customs Office in Port Fairy, in the southwest region of Victoria. It is also associated with Bartholomew Sikes, whose design of a hydrometer was chosen in 1816 as being the most useful and accurate hydrometer. The hydrometer has evolved into the digital version available today to measure density of liquids.Sikes Hydrometer and thermometer in a fitted wooden case with crimson lining inside the lid and dark lining in the base. The case has ten vertical pegs to secure the weights. The brass hydrometer has a spherical float and eight thick brass horseshoe-shaped weights. The serial number is on each section of the float and all weights. Both sides of the float’s upper flat stem have a scale from 0-10, with five divisions between each number. The eight weights are numbered from 20 – 90 in increments of 10. The set includes a mercury thermometer mounted on an ivory back plate labelled with Fahrenheit and Centigrade Scales. The Sikes hydrometer set was made by Loftus of London. The hydrometer model is IID 510, Serial Number is 14674, calibrated by Longs, London.

In the 1600s, William Harvey realised a finite amount of blood circulates in one direction through the body. Jean Léonard Marie Poiseuille introduced the mercury hydrodynometer in the early 1800s for measuring blood pressure. Karl von-Vierordt created the sphygmograph in 1855 and, in 1881, Samuel von Basch created the sphygmomanometer, distinct improvements on the hydrodynometer. In 1896, Scipione Riva-Rocci developed the mercury sphygmomanometer. American neurosurgeon, Harvey Cushing, was an early adopter, and advocate for monitoring patients during surgery and anaesthesia. Blood pressure monitoring is still an essential component of evaluating a patient’s condition.This blood pressure kit is housed in a rectangular, vinyl covered box with metal handle and press-stud lid release mechanism. The lid opens upwards and the glass blood pressure valve and plastic scale is attached to the underside of the lid. The measurements are written in black and go up in increments of ten, from 0 to 300. The glass valve has unidentified increments labelled in red, which is housed within a metal cylinder.

A Fortin style mercury barometer from well-known Australian instrument maker, A.L.Franklin. The column of mercury is supported by the pressure of air on the free surface of the mercury in the cistern at the bottom. Its level can be adjusted to a datum using the screw at the bottom and then the height of the column can be accurately read off using a vernier scale at the top. Attached to a backing timber board with a thermometer. Thermometer made by Townson and Mercer.

This instrument measures elevation by sensing minute changes in barometric air pressure relative to a fixed datum point at sea level or a known elevation, such as the starting point of a major town during a road survey, and has an accuracy of +/- 20 feet when used in experienced hands. The finely divided scale around the perimeter of the face is marked from 0 to 6000 feet elevation and 25 to 31 inches of mercury (Hg) for barometric pressure The single fine counter-balanced hand or pointer rotates anti-clockwise with increasing elevation and decreasing pressure. The label "compensated" indicates that the instrument is constructed to compensate for the effect of temperature changes on the accuracy of readings.
