The set of 20 photographs were taken of a number of archaeological sites in Sunbury of sacred sites and aboriginal rings. The photographs were included in a study of these sites which was published by the Shire of Bulla in the early 1990's.A soil profile showing a whitened lava flow above decomposing timber and soil at the lower level.aboriginal ring sites, george evans collection

The Dräeger Pulmotor was developed in 1907. It addressed previous concerns about lung injury, by limiting both the inspiratory and expiratory pressures. Although still controversial, the Pulmotor was widely distributed and commercially successful. Oxygen from cylinders provided both the inspiratory gas flow and the driving mechanism. Expiration was an active process and gases were sucked from the lungs by negative pressure created by a Venturi effect. This device came with a facemask and harness, with a caution that the operator should take care to prevent air entering the stomach.Draeger resuscitation kit, inside wooden case with handle.

Kaolin is also known as china clay. This specimen came from Dunolly, Victoria and was donated to the Museum in 1868 as part of the Geological Survey of Victoria. This survey helped map and study the geology of Victoria. In Victoria, Kaolin is particularly used as a filler and coating material in paper manufacture. It can also be used in paints, ceramics, rubbers and plastics. There are many kaolin deposits in Victoria but many of these have been mined out and there is not much Kaolin left. Rocks that have a high amount of Kaolinite and it can be formed through the decomposition of other materials. There are two types of Kaolin; hard and soft kaolin. Soft kaolin's are coarse but have a soapy texture. It can also break easily. The hard kaolins have an earthly texture and are finer grained. This means that they are harder to break, unlike the soft kaolin. Hard kaolin's are formed by flocculation in salt water, a process that in basic terms, bonds particles together. Kaolin is a common material in Victoria and that is why it is significant. While this specimen was mined in Dunolly, Victoria Kaolin can also be found Pittong, Pakenham, Bulla, Hallam and Ballarat as well as many other places throughout Victoria. This specimen represents the presence of Kaolin deposits in this region of Australia. It is also significant because Kaolin has many uses and is largely beneficial to many manufacturing processes in Victoria. This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.Two pieces of Kaolinite mineral with shades of white and graygeological specimen, geology, geology collection, burke museum, beechworth, kaolin, china clay, dunolly, geological survey of victoria, kaolinite, victoria, mining, mining deposits, geology of victoria, australia, filler, coating material, paper manufacture, paint, ceramics, rubbers, plastics, decomposition, materials, soft kaolin, hard kaolin, flocculation, particles, salt water

Local waste tip fires can be caused by spontaneous combustion within decomposing waste, ignition of flammable industrial materials, heat build‑up in buried rubbish or a spark from machinery. These fires can produce thick smoke visible across the district, strong chemical odours, ash drifting into nearby residential streets and causing significant concerns among the local residents.A blaze at the Sunshine municipal tip would send smoke across Albion, Ardeer, St Albans, and Sunshine, highlighting the environmental risks faced by residents living beside an ageing suburban waste‑disposal site.Sunshine Tip Fire 297.1sunshine tip, albion

This 5 grave stones of the VBP mass grave in Cherang Ruku were built by the UN-HCR. As told by the local old man, Mr Lim at 80 years old, in 2010, who was in charge of burying these victims from the first day, he confirmed that there were 139 bodies buried by himself. It can accepted that because the name list of the boat was lost during sinking, the name list angraved on the stones was collected by UN HCR member by interviewing the victims who could identified victims. Furthermore the dead bodies, as told by Mr Lim, were washed ashore not in one day. The local residents could not contact to report to the UN HCR many after the accident, what they could do was that they had to quicly bury the decomposed bodies. As told by vitims of the MT065, about 2 - 3 days after the accident, they were called to the beach to identify the bodies. No way they could identify the body because it was swollen and decomposed. Face and parts of the body was eaten by fish.5 grave stones of the VBP mass grave in Cherang Ruku

Malleefowls (Leipoa Ocellata) are shy, ground-dwelling birds that make their homes in Mallee country. The nearby Wyperfeld National Park in Hopetoun is a known habitat. The malleefowl mounds are one of the most fascinating things about the malleefowl. Unlike most birds, they don’t build nests in trees or on the ground. Instead, they create large nesting mounds of sand, soil, and organic material, sometimes up to 5 metres in diameter and 1 metre in height. After the female malleefowl lays the eggs, the heat generated by the decomposition of the organic material inside the mound incubates them. The male bird constantly adjusts the temperature by adding or removing material. It’s a process that can take several months and requires meticulous care, making the malleefowl parents some of the most dedicated. Their breeding season is between September and January, and use the same malleefowl mounds for multiple seasons. Malleefowl chicks often hatch from November to January. Mallee is a type of bushland found in parts of Victoria and South Australia. It’s made up of scraggly, multi-stemmed eucalyptus trees that are very tough and can survive in dry, harsh conditions.

An original Kerr-Grant Microbalance, modified by E.J.Hartung This balance was invented in the chemistry department by Bertram Dillon Steele, later first Professor of Chemistry at the University of Queensland 1910-1930, in collaboration with Professor Kerr Grant, Physics. The design was widely used by other chemists, including Masson's mentor, Professor Ramsay, working in London on newly discovered rare gases (especially Radon), and Professor Hartung in Melbourne, investigating the chemistry of the decomposition of silver salts in photographic processes. The principle of the microbalance was to measure the change in density of a gas by the shift in the balancing beam due to a change in pressure of the gas in the balance case. The quartz balancing beam was made by Bertram Steele who was particularly skilled in glassblowing. A quartz beam is the beam of the Aston microbalance based on the Steele/Grant instrument, and described by F.W. Aston, the inventor of the mass spectrometer. The bulb at one end of the beam contained a fixed amount of air, so that a change in the pressure of gas in the balance case changed the buoyancy of the beam, yielding a displacement in the beam which could be measured. By this means, differences in weight of about 10 nanogram could be measured, in amounts of up to 0.1 gram. Such differences are significant the increase in weight of a metal sample due to surface oxidation (Steele's interest) in the weight loss due to radioactive decay of Radium (Ramsay's work), and in the estimates of density change due to the isotopic distribution of Neon (Aston). Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).An original Kerr-Grant Microbalance, modified by E.J.

In March 1892, Melbourne Butcher John Stamford took a prospective tenant to a house he owned at 57 Andrew Street Windsor. He noticed a 'disagreeable smell' coming from the front rooms. Suspecting foul play, Stamford called the police who quickly discovered a decomposing body and partially clad body of a young woman in a shallow grave under the fireplace. 'Her skull had been shattered and her throat cut'. Two detectives, Sergeants Considine and Cawsey, began investigations. The previous tenant, a 'Mr. Druin' who had rented the house had since disappeared was the main suspect. 'Druin' had arrived in Australia from England as 'Albert Williams' in December 1891 with his 24 year old wife Emily Mather. The body was Emily's. The crime scene investigation proved difficult as the suspect - whatever his real name- had cleaned up the scene very carefully. Much later it was discovered that the suspect was in fact Frederick Bayley Deeming, a former sailor born in Birkenhead, Cheshire, in 1854. In 1881, Deeming deserted his ship and lived in Sydney where he married and had a family. Deeply in debt, he later burned his business down to claim its insurance value and fled to South Africa before he could be arrested. He is believed to have committed numerous frauds and murders in Africa. Eventually found in Uruguay, he spent time in prison in England for fraud. After being released he married Emily and returned to Australia. After leaving England, British police began investigating him over the murder of Mrs Marie Deeming and her four children. Now using another alias, 'Baron Swanston', Deeming was arrested in Western Australia before he left the country in the company of a young woman, Kate Rounsefell, whom he planned to marry. It seems Kate would have been his next murder victim. Brought back to Victoria, in May 1892, Deeming went on trail for the murder of Emily Mather. Despite a strong defense conducted by a brilliant young barrister and 3 times Australian Prime Minister Alfred Deakin, the evidence against Deeming was overwhelming and he was found guilty. Deeming was hanged at Melbourne Gaol on 23 May 1892. He was known to be responsible for at least 6 murders and may have committed others.

This set of photos is from a leather bound album bearing the inscription "HUME RESERVOIR AUSTRALIA" plus 'The Rt. Hon. L. C. M. S. Amery, P. C., M .P.' all inscribed in gold. It was presented to The Rt. Hon. L. C. M. S. Amery, P. C., M. P, Secretary of State for Dominion Affairs on the occasion of his visit to the Hume Reservoir on 2nd November 1927. This album is of local and national significance as it documents the planning and development of the Hume Reservoir up to 1927. It was the largest water reservoir in the British Empire. The album records the pioneering engineering work that went into its construction.2. Detail Plan and Section. Starting from the New South Wales and there will be an earthen embankment 430 feet 6 inches long which is retained by the North Wing Wall. Then come the sluice section 284 feet 3 inches long, the spillway 720 feet long and the South Wing Wall, making a total length of 1,042 feet 6 inches of concrete wall. Beyond the South Wing Wall is earth embankment again to a length of 3,827 feet. The Full Supply Level is R.L.626.00 and allowance has been made for a surcharge of 9 feet. A road will run along the top of the dam at R.L.642.00. The sluice section contains seven offlets, the three nearest the north wing wall being 13 feet in diameter for hydro-electric purposes and the other four 9 feet in diameter for regulation purposes only. There are to be stony sluice gates on the upstream ends of the outlets and needle valves on the downstream ends. The shock of the discharged water will be taken by a stilling pool. Trash racks will protect the intake ends of the outlets. Next comes the spillway section, which is curved on the downstream face, and carried up to within 15 feet of the full supply level. Above that will be a series of piers between which will be the flood gates and on top of which the roadway will be carried. The gates will be 20 feet wide and 15 feet high and will be 29 in number. They will slide down the face of the wall when opened for the escape of the water. The investigation of the control of this cascade of water was made by means of a model and as a result the form of “bucket” or energy dissipater shown on the section of the spillway was decided upon. The earth embankment in Victoria is being constructed by the State Rivers and Water Supply Commission of Victoria who are the Constructing Authority for that State under the River Murray Waters Agreement. The core of the embankment is of concrete 6 feet wide at the base tapering to 2 feet at the top end and is reinforced with steel rods from the level of the decomposed rock upwards. On the downstream side, at about natural surface level, is a tunnel for drainage and inspection purposes. Above the tunnel is a vertical layer of large stones to drain any seepage to the tunnel. Against the core wall is packed selected material of as impervious a character as can be got locally and beyond that the bank is carefully built up in horizontal layers by means of horses and wheel scoops. The upstream slope is 3-to-1 hardening to 2½-to-1 at the top and the downstream slope is 2½-to-1 hardening to 2.07-to-1 at the top. The thrust of the upstream toe is taken by a mass of granite blocks, and this face is protected by concrete laid in situ. The width of the bank at base is 650 feet and at top 32 feet.hume reservoir australia, river murray waters scheme, hume weir diagrams, hume plan details

The West Kiewa Tunnel (tailrace tunnel) was commenced from both ends in 1947. Very difficult conditions were encountered in the driving of this tunnel and this meant the immediate provision of support and later the lining of the tunnel with concrete. Work proceeded steadily and the breakthrough of the two headings occurred on 22nd July, 1950.This historical photograph shows in detail the amount of work necessary to stabilise and support the tunnel walls before lining with concrete. No solid rock was found and the tunneling proceeded through decomposed boulders, gravel and clay, hence the necessity for support and concreting.

The College’s spray was one of the first pieces of surgical memorabilia to come into the possession of the College. It had been used in the Listerian wards of the Glasgow Royal Infirmary, and was presented , along with some other artefacts, by James Hogarth Pringle in 1930. Joseph Lister (1827-1912) is known as a father of modern surgery. His methods of preventing infection were controversial in their time, but are today recognized as a major advance in the practice of surgery. Lister’s life and achievements are too well known to be recounted here. The definitive biography was written by his nephew, Sir Rickman Godlee (PRCSE 1911-13), and published in 1917. Douglas Guthrie gives an glimpse of Lister at work: “...He never wore a white gown and frequently did not even remove his coat, but simply rolled back his sleeves and turned up his coat collar to protect his starched collar from the cloud of carbolic spray in which he operated...” From advances in bacteriology, and discoveries by Robert Koch and others, it became increasingly evident that airborne bacteria were not a significant contributor to sepsis in surgical wounds. They also demonstrated that the body had its own defences against invading organisms, which were seriously compromised by the effects of the carbolic spray. Gradually the use of the spray was curtailed, Lister himself finally abandoning it in 1887. Lister performed the first antiseptic operation, the dressing and splintage of a compound fracture of the lower leg, in 1865. At this time he used carbolic solution by application, and dressings soaked in the solution. The spray was developed later, after many different methods, including carbolic and linseed oil putty, had been tried in order to reduce the harmful side-effects of undiluted carbolic acid. The steam spray was developed in 1869, and announced to the medical world in 1871. Lister’s purpose in adopting the spray was to kill airborne bacteria in the vicinity of the operation before they could reach the patient. It came to be used all over the world for many years. However, it had serious disadvantages, which even Lister acknowledged. The principal problem was the inhalation of carbolic vapour by everyone in the vicinity, including the patient and the operator. In addition, if the patient had been anæsthetized using chloroform, the gas lights decomposed the vapour into chlorine gas, making any procedure an ordeal of endurance.The spray consists of a steam boiler heated by a wick, a nozzle for the steam to escape, and a glass jar for the carbolic solution. Fuel for the wick is carried in a tank at the base. Valves regulate the pressure of the steam, and the nozzle is adjustable. The boiler is made of cast iron, the fittings are brass, and the handles are of wood. Empty, the apparatus weighs 8 lbs (3.2 kg). lister, carbolic spray, antiseptic
