This Sikes brass hydrometer was manufactured by the optical and scientific instrument makers Kasner & Moss of 17 Collins Street West, Melbourne, in the latter part of the nineteenth century. The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. This hydrometer set was donated to Flagstaff Hill in 1979 by local wine and spirits merchants Lynch Bros of Fairy Street, Warrnambool. Giffen Russell had established the business in 1878, and Harry Lynch took it over in the 1930s, and after he passed away in 1953 Kevin Matthew Lynch became proprietor of K M Lynch Food and Liquor. The business closed in the 2010s. The hydrometer may date back to the establishment of the business in 1878, as Kasner & Moss were selling hydrometers in Melbourne from 1864. 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. This hydrometer and its fitted and hinged wooden container show signs of heavy and protracted use in a working environment. Although the instrument has some parts missing and has been recently repaired, the original quality of the inlaid box and the fine engraving on the instrument and the attachable weights, are indications of the hydrometer’s very real value when new. This Sikes hydrometer, bearing the maker's mark of “Kasner & Moss Melbourne” and the registered number “20373”, was presented to the purchasing public as a precision-made instrument designed for professional use. The Sikes hydrometer is of local significance because of its implied association with the alcohol trade in the southwest region of Victoria. It was donated by a family member of Lynch Bros, a local licensed outlet for wines and spirits in the period before the general relaxation of liquor licensing laws in the State of Victoria. It may have belonged to Griffin Russell who established the liquor store in 1878.Hydrometer; original Sikes brass hydrometer in a polished wooden case with an inlaid plaque on the lid. The brass float is a sphere with a thin flat upper stem and a short, lower stem with a bulb-shaped end. The upper stem is engraved scale on both sides with the numbers 1 to 10, and five divisions between each number. There are ten fixed pegs in the base to secure the thick brass horseshoe-shaped, numbered, various-sized weights (20, 30, 40, 80, 90); the free pegs would have originally stored another five weights (10, 50, 60, 70, and 100). The empty compartment in the box suggests another part in the initial set, probably a thermometer. The fitted, fabric-lined box has two brass closures and two brass hinges. The scientific instrument shows signs of heavy use and repairs. The Serial Number on the float matches the Serial Numbers on the weights. The plaque on the lid, the float and the weights have inscriptions. Made by Kasner & Moss, Melbourne. Plaque: “SIKES HYDROMETER / KASNER & MOSS / MELBOURNE” On float's lower stem: “SIKES 20373” On one thin edge of the float's scale, engraved in script “Kasner & Moss” and stamped “MELBOURNE”, and symbol“P” rotated 90 degrees.

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.

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

In 1941, the scientific instrument manufacturing firms of  Henry Hughes & Son Ltd, London, England, and  Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.

Adams jnr wrote many elementary scientific works, as well as on the use of mathematical instruments. He often combined in his written works with religious themes and scientific content, often against the prevailing thoughts of the time. According to one popular magazine of the time (Gentleman's Magazine), his works were often accused of "growing errors of materialism, infidelity, and anarchy". He started writing at a young age and developed a love for it, his main interests included math and science, these subjects he often expressed in his written essay's. Notable works from Adams are. An Essay on Electricity, and Magnetism (1784). Essays on the Microscope (1787). An Essay on Vision, briefly explaining the fabric of the eye (1789). Astronomical and Geographical Essays (1790). A Short Dissertation on the Barometer (1790). Geometrical and Graphical Essays, containing a description of the mathematical instruments used in geometry, civil and military surveying, leveling and perspective (1790). Lectures on Natural and Experimental Philosophy, in five volumes (1794).George Adams Sr and Jnr were both notable opticians and scientific instrument makers of the 18th century. Their contribution to scientific innovation and optical development cannot be underestimated. Having one of their early drainage levels in the collection and in extremely good condition is an asset to the Flagstaff collection.Drainage level or optical level.

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.

This apothecary weights set was supplied by the company 'H B Silberberg & Company, Melbourne.' The company used this name in Melbourne from 1903-1917, then changed their name to “H.B. Selby & Company”. The firm specialised in the manufacture, import and supply of scientific instruments, laboratory apparatus, chemicals and industrial equipment. It was founded in Melbourne around 1889 by Carl de Beer and traded under the name of his brother Ernest de Beer and Company. Herbert B Silberberg joined the de Beer partnership in 1903 and, later in the same year, bought the de Beers’ shares in the business. Silberberg carried on as de Beer, Silberberg & Company for four months, after which he changed the name to H B Silberberg & Company. (Australian National University Archives; H B Selby and Company Proprietary Limited) This apothecary weights set 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 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 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 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 ) 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 in 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 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 to the Nhill Hospital 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 at 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 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 included 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 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 1933-1938. His practitioner’s plate from his Nhill surgery states “HOURS Daily, except Tuesdays, Fridays and Saturday afternoons, 9-10am, 2-4pm, 7-8pm. 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 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 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. (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 surgeon at the Warrnambool Base Hospital 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 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. Their interests included organisations such as 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. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery. Apothecary or pharmacy weights set, metric, in fitted wooden box with metal hook latch. Part of the W.R.

This measuring ruler was used in the planning and making of components for the ship model Sovereign of the Seas. It is part of a collection of objects used by Jim Williams, maker of fine ship models from about 1930-1955. Most of the components for the models, as well as many of the tools, were handmade by Jim Williams. Jim’s family has donated the ship model “Sovereign of the Seas” and many tools, accessories and documents used in the making of this and other ship models have been donated to Flagstaff Hill Maritime Village. Ship model of HMS Sovereign of the Seas, scale model of 17th Century English war ship, was handmade and carved from plans, enclosed in airtight glass case. All components of that model, including even the smallest pulleys, were hand crafted using tools designed and made by Jim. Outstanding details include functional rigging and moving cannons. Please see our record 3732 of the mode Sovereign of the Seas for further details of the ship and the maker. This ruler made by instrument makers J Rabone and Sons of Birmingham, is connected with the hobby and skill of ship model making that has been crafted as a leisure activity for many generations. The hobby is often chosen by serving and retired mariners who appreciate the connection with maritime history. This ruler was used by local Warrnambool man, Jim Williams, who was employed at Cramond and Dickson clothing store, and then at Fletcher Jones menswear for 27 years. It was used in making components for the model of the historic ship, the Sovereign of the Seas. The Sovereign of the Seas was a historic 17th century English war ship with important maritime heritage. Ruler, folding, wooden with brass hinges. Maker J. Rabone & Sons, Birmingham. Model No. 1375.

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

William (Billie) Blackmore was born at or near Richmond, Victoria.At age 26 he joined the A.I.F. in WW1 while he was employed at Orbost as a labourer. He served in Egypt and France until following his discharge on December 20th 1916, he transferred to 15th Machine Coy in January 1917. He was severely wounded, repatriated to England until after an operation and further hospitalisation returned home to Orbost .In Orbost he did farm work for George and Elizabeth Trewin, eventually building a small shack on what was Rupert Leatham's property at Brodribb. He fossicked for gold in a nearby creek and the story goes that he buried his coins around the property. He donated these scales to the Orbost & Districet Historical Society. (more details and ref.

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 Australian Customs Service, Melbourne, donated a set of gauging instruments, and Port Fairy Customs donated another instrument, the Sike’s Hydrometer, to Flagstaff Hill Maritime Village, all of which were no longer required. However these ullaging tools were in use for many years by Customs officials, called Gaugers. Ullaging is a term describing the measurement of the amount of liquid remaining in a container of spirits such as a cask or barrel. It can also measure the free space or head space remaining. The primary role of customs officers in Victoria was to calculate the tariff or excise duty payable on goods imported into Victoria. (Excise duty is a tax on goods produced within a country, and customs duty is imposed on imports.) Customs officers spent a great deal of their time measuring and weighing goods, and then calculating the amount of duty to be paid by the importer. The tariffs for different products varied, and officers consulted published lists. Calculating the duty payable on a barrel of brandy was a detailed task. The gauger had to measure the barrel to determine its volume. Barrels were irregular in shape, and finding the volume required several measurements and checking tables of figures. Alcoholic content was then measured with a hydrometer. The duty paid varied according to the alcoholic strength of the spirits. Uniform national customs and excise duties were operative in Australia from October 1901. These tools were still being used in Australia in the 1950’s. The Federal Government still imposes excise taxes on goods such as cigarettes, petrol, and alcohol. The rates imposed may change in February and August each year in response to changes in the consumer price index. ULLAGING TOOLS (1) Head Rod - this instrument measures the diameter of the heads (top and bottom ends) of a cask or barrel. The shaped brass pieces on the head rod enable the diameter of a barrel to be measured inside the chimes at the head end. The slide rule could then be used to calculate the internal volume of the barrel. On the reverse side is a set of ullaging scales, used like those on any ullaging rule, to calculate the volume of liquid in a partially filled barrel. (2) Bung Rod – this instrument measures the diameter of a cask or barrel when it is lying on its side. It is a rod that fits into the ‘bung’ hole of a cask and is long enough be extended to reach the opposite side of the cask. The brass sliding pointer can be moved to mark the ‘wet’ line. When the rod is removed the bung measurement can be read from the scale on the rod. (3) Long Calipers - this instrument measures the length of the cask between the heads. It has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards then turned inwards at the ends so as to reach over the heads of the casks without touching the projecting ends. The centre pieces enable it to extend or contract, changing the distance between the two other parallel sides, the distance they are apart being shown by the rule on the sliding pieces. (4) Cross Calipers – this instrument is used to take the bung diameters of casks, or "the Cross " as it is called. This instrument has two rules sliding beside each other, each end having another piece of wood fixed firmly at right angles downwards, together forming a 3 sides of a rectangle with the centre pieces enabling it to extended or contracted, changing the distance between the two other parallel sides, the distance they are apart being shown by a the rule on the sliding pieces. (5) Sike’s Hydrometer – this instrument is used to gauge the strength of different alcoholic spirits when fitted with the different weights in the set. Every set is individually calibrated to ensure that it meets the exact Standard Weight and Measure compliance, then every piece in that set is stamped with the same number by the Calibrator, to ensure that the measurements are taken using the same hydrometer set.

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

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.

The nested cup weights were designed to make the transport of weights, essential items in most commercial transactions, more convenient. This idea goes back to Roman times. In the nested cup form, a series of weights shaped into cups are set one into the other. Each cup fits precisely into the next, larger sized cup which each larger example weighing exactly twice that of the one previous. The Troy weight system was used for precious metals and gemstones.7 x Brass troy measures of various sizes.

Jakob Maul (1866-1953) founded a metal works factory in 1912 at Zell in Odenwald not far from Frankfurt. He was born the son of a winegrower from the Rheinhessen region of Germany that lies on the left bank of the river Rhine. At the age of 45, he started a metal works factory to produce various types of scales but during the second world war the factory was bombed and production ended. Production for the manufacture of scales resumed in 1948. In 1953 at his death Jakobs son Fritz Scharmann an engineer who had been working with his father since 1923 took over the management of the Maul companies. In 1970 the production responsibilities for Philip J Maul was taken over by Porti Office Equipment who was based in Hamburg. The company has undergone several integrations with subsidiary companies. Today the company has diversified into different areas one of which is manufacturing solar scales. An original postal scale made in Germany before the Second World War and regarded today as a collector's item.

Before 1851, letters sent through the mail were charged by the number of sheets it contained and the distance it travelled. For example, a letter consisting of one sheet of paper was charged the single rate; a double letter, that is two sheets, was charged double the single rate, a treble letter, was charged three times the single rate, and so on. In other words, each additional sheet of paper increased the charge by one rate. In Great Britain. Sealing a letter in an envelope effectively put an end to postal clerks' ability to count the number of sheets in a letter and an alternative method of determining the postage had to be found. Overweight mailings had previously required the items to be weighed but with the introduction of the Uniform Penny Postage act of 1839, the public could mail a letter not exceeding a half-ounce in weight within the United Kingdom for one penny if prepaid, or two pence if paid on delivery. At about the same time that the adhesive postage stamps and envelopes made their appearance, postal administrations began to experiment with strategically placed street letter boxes, known as pillar boxes because of their round, pillar-like shape, that permitted the public to mail letters from a place other than from a post office. For all these reasons, the use of postal scales became the nucleus of every post office. Scales had been in use since ancient Egyptian times so their use for everyday commerce was not unusual in the 1800s. What was new in 1840 was their ubiquitous use throughout the postal system. No post office could function effectively without one. Although the earliest scales used in post offices did not differ markedly from the ones in general use as time went on they were adapted specifically for postal use. For example, a paper sleeve, also known as a weight sticker, was attached that showed the applicable rate of postage for any given weight. This innovation was quite a time saver as postal clerks no longer needed to weigh the item first and then refer to a separate chart to determine the required postage for that particular weight. Victorian postal scales were used in village Post offices in the late 19th century, of which there are many examples today for sale. No maker can be attributed to the manufacture of the item.
