There are several different designs of drench guns within the NWM Collection that show the change in their development over time. On the left side of this gun white paint indicates the adjustable dose lever. It is a sliding scale from 10 to 0 cubic centimetres of liquid (now typical measure in millilitres). It also has a small and straight tip suggesting this gun was typically used for dosing Lambs as opposed to ewes. The manual adjuster helped to minimise cases of overdosing which can be fatal for livestock while the additional curvature helped to ensure the liquid reached the desired location within the sheep’s mouth. This desired location is on the left rear of the sheep’s tongue (from the sheep’s point of view) as this is where the oesophagus is located. The main risks are that drench may be delivered into the lungs via the trachea or “windpipe”, which can also prove fatal. The opening to the trachea which leads to the lungs is in the middle of the back of the throat. Another risk is the throat can also be damaged due to rough handling.Silver metal with black finishing drench gun. Straight tip on gun protrudes from the body which feature a thin squeezable trigger to the front of the body. The main bulk, which the trigger is squeezed towards has silver cylinder on top of the handle where tubing carrying the liquid drench into the gun attaches.

This type of balance scales allows precise measurements to be achieved by ensuring that the balance's fulcrum is essentially friction-free by attaching a pointer to the beam which amplifies any deviation from a balance position; and finally by using the lever principle, which allows fractional masses to be applied by movement of a small mass along the measuring arm of the beam. The standardization of the weights used – and ensuring traders used the correct weights – was a considerable preoccupation of governments throughout this time and inspections were held regularly. When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses.Set of small scales possibly from a travelling boxed set due to their small size, similar to those used in an apothecary and weighing gold.

Victoria became a separate colony of the United Kingdom on 1 July 1851; however it took until 1864 for a workable system of weights and measures administration to be introduced. Standard of weights and measures were obtained and issued to local authorities to administer in their local areas. These standards were numbered, as were the Crown stamps used by inspectors to indicate that trade weights and measures had been checked and found to be legal to use in the day-to-day businesses of local traders.

Sets of scales similar to these were very common in households throughout Australia. Between 1960 and 1988 Australia gradually adopted the SI units (Standard International) or metric units.

Sets of scales similar to these were very common in households throughout Australia in the 19th and 20th centuries. Avery of Birmingham were a British manufacturer of weighing machines. The company was founded in the early 18th century and took the name W & T Avery in 1818. The company produced a wide range of scales ranging from industrial scales and weighbriges to small scales for domestic use, such as these scales. At the time of the death of the last Avery family member in 1918, it employed over 3,000 people and had businesses all over the world.

Troy weight is a system of units of mass from an unknown origin. While the name Troi is believed to have come from Troyes in the north east of France the system used primarily in the precious metals industry and adopted in Australia originated in 15th century England. Troy weight units are the 'grain' and 'pennyweight' (24 grains), the troy ounce (20 pennyweights), and the troy pound (12 troy ounces). One troy ounce equals 31.1034768 grams. The troy ounce and grain were also part of the apothecaries' system and was long used in medicine, but has now been largely replaced by the metric system (milligrams). When the Weights and Measures Act was passed in Victoria in 1862 local inspectors were established throughout the colony to ensure accuracy particularly in the weighing of gold. By the 1870's each local council had a set of standards that were used to test the scales, weights and measures of local merchants and businesses.

The Gem The Poseidon Rush. Tarnagulla, Saturday. Article - The Albury Banner and Wodonga Express (NSW : 1871 - 1938)Friday 8 February 1907 - Page 43 The Poseidon Rush. Tarnagulla, Saturday. Several indicators and quartz leaders on the Woolshed Hill have received considerable attention during the last fortnight. In some claims the stone looks very promising, and nice tracings of gold have been obtained. Wragg Brothers struck it rich yesterday. At a depth of 12ft. on the bedrock they discovered a nugget specimen 206oz. in weight, which has been christened the 'Port Arthur. The party also had the good fortune to find two other specimens close, by, one weighing 23oz. 15dwt. and the other 24oz.These were named 'The Twins,' the Wragg Brothers bearing that distinction. In this claim about eight weeks ago the Gem (88oz.) was unearthed. THE POSEIDON RUSH. Article Illustrated - Leader (Melbourne, Vic. : 1862 - 1918, 1935)Saturday 29 December 1906 - Page 33 THE POSEIDON RUSH. It is only about five weeks since this rush was opened by John Porter, but since that time a marvellous change has taken place. The quietness of the bush has given place to a scene of wild excitement, and each week this is intensified by the discovery of large nuggets. When Smith, Rogers and Stephenson picked out their slug on election day, no one dreamed that larger ones were lying only a few feet away, but such was the fact. On Tuesday afternoon two immense slugs, one of which weighed 960 oz., and the other 373 oz., were found in adjoining claims within a few minutes of each other. The finding of these created a scene which it is difficult to describe. "I've got one, “was shouted from the claim of Bert Williamson and T. Stephenson, two men just entering into manhood. They were seen excitedly digging round a lump of gold, one of them with a double-ended pick, the point-of which he broke in his anxiety to unearth it. This slug is nine inches long by seven inches by 43 inches, and is very similar in appearance and size to the big nugget got previously in the adjoining claim. It has been cleaned and smelted, and has yielded 306 oz. of pure gold of the best sample. Before the excitement caused by the discovery of the last nugget had sub-sided, there was a shout from an adjoining claim. Sam Woodall, a Llanelly miner, felt his pick strike a hard yielding sub-stance, and, satisfied that he had struck a nugget, called the attention of his mates to the fact. He soon levered it out of the ground with his pick. Taking it up in his arms he staggered out of the claim with it, and in a minute or two was sur-rounded by hundreds of men who rushed from all over the field to view it, and to feel its weight. It was certainly a magnificent specimen, and the fortunate miners were congratulated on all sides. Its weight was guessed to be a hundredweight, and probably in its then dirty state it would nave turned the scales at that. In a few minutes the crowd was so dense that it was impossible to get a close inspection. The nugget was first taken to Newbridge under escort, then through Llanelly to Tarnagulla, where it was lodged in the Union Bank. It was found that the bank scales were not sufficiently large to weigh the mass. By tying a number of large weights together, and suspending them from a steel bar, a fairly accurate weight was obtained, and it just balanced 80 lb., or 960 oz. The nugget measures 16 in. x 10 in. x 5 in. The party was cheered as it drove up the main street here, and the sight of an armed escort was quite a novelty. The nugget was held aloft in a tin dish for inspection by the crowd. These nuggets were found in the shallow workings, and neither of them were a foot under the surface. The ground is a black loamy soil; there was no appearance of wash whatever, and no one knowing anything of alluvial mining would think of searching for gold in such a spot. All those who have claims on the hillside are breaking out all the dirt in a face from the surface to the reef, which is a mixture of lime and sunstone, and searching for nuggets. The ground is carefully pulverised so that nothing shall be missed. Some are puddling the whole of it, but it is hardly payable. Where the big nuggets are now being found, the ground has been pegged out and abandoned more than once since the rush started, and shares in the claims have been purchased for small amounts. Smith was given a third share in the claim where the first nugget was found for puddling the dirt big lump was discovered, by Woodall, Condron, Brooks and Eva, two of them sold a sixth share for £5 a few days ago to a man named Woods, who only worked a few days and sold out again for 50/. Some fancy prices are now being offered for shares in the claims in the vicinity. Woodall holds a third share, Condron and Brooks three-quarters of a share each, and Eva a sixth share. The largest nugget has been christened "The Poseidon." The names given to the other nuggets obtained previously are as follow: — Wragg Bros., 88 oz. nugget, "The Gem"; Smith and party's 378 oz. nugget, which was unearthed on election day, has been fittingly named "The Federal"; Jackson and Hughes 152 oz.specimen, "The Little. Beu"; Williamson and Stephenson's 373 oz. nugget is said to be called "The Christmas Box."

This set of baby scales is believed to have been used in a Baby Health Centre in Warrnambool. The first Baby Health Centre in Warrnambool was opened in Liebig Street in October 1921. It was initially run by Sister Riley. The development of Baby Health Centres in Victoria was largely due to the work of Dr Isabella Younger-Ross (1887-1956). She was born in Warrnambool to Henrietta and John Younger (the Younger department store operated in Liebig Street Warrnambool for over 60 years). Isabella Younger Ross studied medicine in Melbourne and Glasgow and she was a prominent worker in the field of maternal and infant welfare for over 40 years. These scales are retained as an example of the type of equipment used in baby health centres in the early to mid 20th century. It will be useful for display.This is a metal set of scales with a rectangular base tapering at one end. At the top is attached a metal receptacle for holding a baby and underneath this on top of the base is the scale mechanism with a metal measuring device. The item is painted yellow and green but the paint is well rusted and peeling in places. 15 lb.warrnambool baby health centres, dr isabella younger-ross

This is a set of 30 photographs of Royal Australian Survey Corps (RA Svy) personnel from Central Comd Fd Svy Unit (Adelaide) on Aerodist survey operation - Project C4 in Eastern Arnhem Land, Northern Territory in 1967. Photos of personnel were taken either at the operations base at Numbulwar or the main base at Gove (Nhulunbuy). RA Svy conducted nineteen Aerodist operations for 12 years from 1964 to 1975. Aerodist MRC2 was a tellurometer-based system adapted for aircraft to accurately measure distances between non-intervisible ground survey stations, using the aircraft as an intermediate station. Lower order geodetic results could be achieved by survey network trilateration. The measured distances between stations formed survey networks from which each station’s latitude and longitude was computed. Aerodist MRC2 was RA Svy’s major horizontal control survey tool for mainly medium scale topographic mapping (scale 1:100,000 Class A being spatially accurate to within 50 metres) in PNG, northern NT, north-west WA, Kalimantan Barat (West) Indonesia, Sumatra Indonesia, Gulf of Carpentaria and Cape York, QLD. In 1967, the Aerodist MRC2 Master equipment was installed in the aircraft featured in this set of photos, Executive Air Services’ (Essendon VIC) Grand Aero Commander VH-EXX. It was the same aircraft type and company contracted to Division of National Mapping for Aerodist MRC2 surveys. From July to October 1967 the aircraft was attached to Central Comd Fd Svy Unit (Adelaide - Major Don Ridge) on Project C4 eastern-Arnhem Land NT, where 317 Aerodist lines measuring 17,300 line miles were successfully completed. This was the most productive Aerodist project thus far. The most common helicopter used by RA Svy up to 1972 was the civilian Bell 47G-2 and the Sioux Light Observation Helicopters (LOH), the Australian Army’s equivalent featured in this photo set. These light observation helicopters had a limiting load carrying capacity of up to about 500 pounds. By comparison, one Aerodist team including two people weighed up to 1,500 pounds.

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. But wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Wind speed can be measured using a variety of anemometers. This simple hand-held Venitimer was made by Elvometer in Sweeden, probably in the 1960s, and was designed for principally for mariners. Some models have a compass in the handle to measure wind direction. The small inlet hole on the side is faced towards the wind and air pressure lifts small plastic disk inside. The upper tube is tapered so that as wind speed increases more air escapes and stronger winds are needed to raise the disk. Wind speed in MPH is read from the side of the clear plastic tube. The waterproof container has instructions on use and conversion scales.

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.

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. The amount of fine fuel available can increase rapidly from nearly zero when fuel moisture content is more than 16% after rain or a heavy morning dew, to many tonnes per hectare as fuel dries out later in the day and the moisture content drops below 9%. This explosive escalation in the amount of available fuel can happen over a few hours on hot and windy days. A sling psychrometer is a simple device for determining air temperature and relative humidity. It contains two thermometers, one of which is covered with a wick saturated with ambient temperature liquid water. These two thermometers are called dry bulb and wet bulb. When the sling psychrometer is spun rapidly in the air, the evaporation of the water from the wick causes the wet bulb thermometer to read lower than the dry bulb thermometer. After the psychrometer has been spun long enough for the thermometers to reach equilibrium temperatures, the unit is stopped, and the two thermometers are quickly read. A psychrometric scale on the side of the instrument is then used to convert the dry bulb temperature TDB and the wet bulb temperature TWB into humidity information. The wet bulb temperature is approximately equal to the adiabatic saturation temperature. The thermometers fold back into the plastic handle when not in use.
