Early cylinders were coloured as their maker saw fit, usually black, perhaps with a white top for oxygen. The Americans first achieved standardisation, but other countries do not follow American Standards. Australia follows the colour-scheme of the British Oxygen Corporation. The body is coloured individually for each gas, viz: compressed air, grey; carbon dioxide, brown; oxygen, black; nitrous oxygen, blue’ cyclopropane, primrose-yellow’ ethylene, mauve. Panels of other colours may appear on the body, but indicate technical points of cylinder-design and do not concern the anaesthetist.

The O'Shannassy Weir was a small Weir created in 1911 and completed in 1913, and was the originating point of outflow into the Aqueduct. In 1928, it was replaced by the much larger O'Shannassy Reservoir. The Weir had water moving along the Aqueduct to the Surrey Hills Reservoir. Many structures at the Weir precinct have survived and remain in-situ.The O'shannassy Weir and Aqueduct contains a wide range of intact and diverse features. This demonstrates the way in which the Board constructed and managed the water supply that flowed through farmland and forest areas subject to timber milling. The caretakers residences that are located along the aqueduct were utilised by caretakers who were responsible for maintaining one of their four sections of the channel. This transparency is significant for its historic association to the establishment of the weir and to those who worked on the project, and at the quarters. weir, o'shannassy, aqueduct, reservoir, melbourne water, mmbw, staff

This gull specimen is a young Herring Gull (Larus argentatus). It is a large gull and one of the most well known of the gulls. This particular species can be found in Northern Europe, Western Europe, Central Europe, Eastern Europe, Scandinavia and the Baltic States. Juvenile and first-winter Herring Gulls are a brown colour with some darker streaks with a bark bill and dark eyes. These colours identifies this particular specimen as a juvenile bird. These birds are commonly seen near the seaside and are omnivores who scavenge from garbage dumps, landfill sites and sewage outflows. This specimen is part of a collection of almost 200 animal specimens that were originally acquired as skins from various institutions across Australia, including the Australian Museum and the National Museum of Victoria, as well as individuals such amateur anthropologist Reynell Eveleigh Johns between 1860-1880. These skins were then mounted by members of the Burke Museum Committee and put-on display in the formal space of the Museum’s original exhibition hall where they continue to be on display. This display of taxidermy mounts initially served to instruct visitors to the Burke Museum of the natural world around them, today it serves as an insight into the collecting habits of the 19th century. This specimen is part of a significant and rare taxidermy mount collection in the Burke Museum. This collection is scientifically and culturally important for reminding us of how science continues to shape our understanding of the modern world. They demonstrate a capacity to hold evidence of how Australia’s fauna history existed in the past and are potentially important for future environmental research. This collection continues to be on display in the Museum and has become a key part to interpreting the collecting habits of the 19th century.This specimen is a juvenile Herring Gull with pale cream and brown coloured plumage. It has a dark bill and dark legs with webbed toes. The eyes are small and are made of glass. They are a pale brown and black colour. The feathers on on the lower back and tail are a darker brown colour compared to the pale plumage on the rest of the bird.Paper Tag: "2yd variega[ted]... Catelogu[e]..."
