Listerine is a brand of antiseptic mouthwash product named after Sir Joseph Lister, Bt. FRS (1827 – 1912), who was a British surgeon and a pioneer of antiseptic surgery. By applying Louis Pasteur's advances in microbiology, he promoted the idea of sterile surgery while working at the Glasgow Royal Infirmary. 1865 Lister successfully introduced carbolic acid (now known as phenol) to sterilise surgical instruments, clean wounds, and for washing surgeons hands before and after operations. These measures led to a reduction in post-operative infections and made surgery safer for patients. “Listerine” was formulated by Dr. Joseph Lawrence and Jordan Wheat Lambert in St. Louis, Missouri, in 1879 as surgical antiseptic, it was given to dentists for oral care in 1895 It was later sold, in distilled form, as both a floor cleaner and a cure for gonorrhoea. But it wasn't a runaway success until the 1920s, when it was advertised as a solution for "chronic halitosis"— a then obscure medical term for bad breath.. In just seven years, the company's revenues rose from $115,000 to more than $8 million.. In 1885, Lawrence sold his share to the Lambert Pharmacal Company. Listerine was packaged in a glass bottle inside a corrugated cardboard tube for nearly 80 years before the first revamps were made to the brand. In 1992, Cool Mint Listerine was introduced in addition to the original Listerine Antiseptic formula and, in 1994, both brands were introduced in plastic bottles for the first time. . From 1921 until the mid-1970s, Listerine was also marketed as a preventive and remedy for colds and sore throats. In 1976, the Federal Trade Commission ruled that these claims were misleading, Originally marketed by the Lambert Pharmacal Company (which later became Warner-Lambert), since 2006 it is manufactured and distributed by Johnson & Johnson In 2009, Johnson and Johnson launched a new alcohol-free version of the product called Listerine Zero.

This type of mobile spring weighing scales were in high use before legislative Weights and Measure standards where in force throughout Australia. This was in a time when a "mans word and handshake" was his legal document. It was a time, especially in rural areas that the term "she'll be right" was extensively used and these types of scales (the accuracy over time) would produce a near "enough is good enough" measure. These scales are very significant for the rural produce within the Kiewa Valley. Rural produce such as hay milk and butter tubs,tobacco bundles could be easily weighed (in relatively smaller packages) for both markets and for use within the valley.This spring scale (!/2 Once to 4lb) was used as general weight scale. Because it is spring loaded the accuracy would fade over time and by over weighted loads. The spring enclosure is made from cast iron painter black. There is an iron ring at the top (attaching/holding) and an iron hook at the bottom (holding). There is a brass front plate with engraved markings(on the left side) running from top to bottom and a movable pin weight indicator running in the middle indicating the weight of the item being weighed.At the front top"SALTER'S SPRING BALANCE 4LB BY 21/2 OZ" underneath "No 1A" At the bottom in smaller print "MADE IN ENGLAND PATENT"weighing instruments, spring balances

This analog voltmeter is quite a large (industrial type) apparatus which permits the easy monitoring of electrical variations within the large SEC Victoria Hydro Scheme's electrical generators. These generators are powered by the hydro force of "stored" water at a higher altitude. The establishment of both the NSW and Victorian Hydro schemes was achieved from the mid 1900's to the 1960's. At this point in time the need for additional power sources to quench both an industrial and domestic demand for electricity was purely an economic and not and environmental (carbon reduction) factor. This hydro scheme was instigated by "the Government of the day" as a bold move and was the major force of the World War II refugee and "technical" workforce inclusion of skilled and unskilled migration into the Australian environment. Although this mass "invasion" of workers with families was thought of in some circles as intrusive, the expansion of population post war years and its integration into the Australian rural sector, produced the multi- lingual multi-cultural diversity of later years. This voltmeter is very significant to the Kiewa Valley as its use was introduced during the Kiewa Hydro Scheme. Although only a small apparatus it was part of the explosion of human resources into the valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both an industrial and a larger residential community. This evolution in the valley created a change, not only in the "physical" landscape but also the socio-economic expansion which permitted other "tourist" based industries into the valley. This analog volt meter has two metal rods protruding from the "back" of instrument with screw on points for the negative and the positive leads allowing the "current" to flow across the calibrated resistors to indicate on the "face" side the strength of the voltage "power". The "face" of the instrument has a zero point and then five evenly graduated marks from Zero to the "100, 200 and 300" marked points of measures. A large "V" below these pointers indicates that they represent levels of voltage. Three small screws hold the "face" in place. At the back of the meter is an aluminium "clasp" with three protruding screws (positioning fasteners) and a a screw tightening fixture for the correct fastening of the "clasp" into the correction location on the meter "board".Manufacturer's logo "CSG" underneath "ITALIA"kiewa valley tourism, victorian alps, alternate energy supplies, alpine population growth

This milli-volt meter was manufactured after 1950 and used by the SEC Vic (Kiewa Hydro Electricity Scheme) from that date until late 1900's. It was used to measure very small voltages associated with the operation of the various Hydro Generators. The readings were able to be shown by the resistor in use in the current circuit. During this time period, high quality testing instruments were either sourced from Europe or England.This milli-volt meter is very significant to the Kiewa Valley as it was used by those electrical technicians, who were part of the Kiewa Hydro Scheme. An "off spin" from the Scheme was the beginning of an explosion in "human" resources into the Kiewa Valley. This influx of population transformed the region from that of a basically quiet rural region to one which evolved into both industrial and larger residential community. This evolution in the Kiewa Valley created a change, not only in the "physical" landscape(better roads and infrastructure), but also the socio-economic growth within the Valley allowing other "tourist" based industries to expand within the valley and Alpine areas.This millivolts DC meter was used in the 1950's. It is contained in a wooden box and has two coloured (red/black, positive and negative) screw tight knobs which have bake-lite connections. It also has a covered (black tin) view meter marked from zero to 10 millivolts. Underneath this and within a round bake-lite is a small adjustment screw.

Many Orbost babies were weighed on scales using these weights. Used in early 1930's.The early 20th century saw an emphasis in Australia on the reforming of mothering practices. There was a desire to improve infant mortality rates and produce healthy, well-adjusted citizens.Government organisations, in particular hospitals and baby clinics. encouraged mothers to measure their babies and regulate their feeding patterns. By the 1930s most mothers had been influenced to a greater or less extent by these new approaches to infant care. These weights are representative of that period.Two steel circular 10lb weights used with 106.1 scales used to weigh babies at Orbost Hospital.

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".

An octant is an astronomical instrument used in measuring the angles of heavenly bodies such as the sun, moon and stars at sea in relation to the horizon. This measurement could then be used to calculate the altitude of the body measured, and then the latitude at sea could also be calculated. The angle of the arms of an octant is 45 degrees, or 1/8 of a circle, which gives the instrument its name. Two men independently developed the octant around 1730: John Hadley (1682–1744), an English mathematician, and Thomas Godfrey (1704–1749), a glazier in Philadelphia. While both have a legitimate and equal claim to the invention, Hadley generally gets the greater share of the credit. This reflects the central role that London and the Royal Society played in the history of scientific instruments in the eighteenth and nineteenth century's. There were also two others who are attributed to having created octanes during this period, Caleb Smith, an English insurance broker with a strong interest in astronomy (in 1734), and Jean-Paul Fouchy, a mathematics professor and astronomer in France (in 1732) In 1767 the first edition of the Nautical Almanac tabulated lunar distances, enabling navigators to find the current time from the angle between the sun and the moon. This angle is sometimes larger than 90°, and thus not possible to measure with an octant. For that reason, Admiral John Campbell, who conducted shipboard experiments with the lunar distance method, suggested a larger instrument and the sextant was developed. From that time onward, the sextant was the instrument that experienced significant development and improvements and was the instrument of choice for naval navigators. The octant continued to be produced well into the 19th century, though it was generally a less accurate and less expensive instrument. The lower price of the octant, including versions without a telescope, made it a practical instrument for ships in the merchant and fishing fleets. One common practice among navigators up to the late nineteenth century was to use both a sextant and an octant. The sextant was used with great care and only for lunar sightings while the octant was used for routine meridional altitude measurements of the sun every day. This protected the very accurate and pricier sextant while using the more affordable octant for general use where it performs well. The invention of the octant was a significant step in providing accuracy of a sailors latitude position at sea and his vessels distance from land when taking sightings of land-based landmarks.Octant with metal handle, three different colored shades are attached, in wooden wedge-shaped box lined with green felt.

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 John E. Hand & Sons Company was founded in Philadelphia in 1873, quickly gaining a reputation as competent manufacturers of nautical instruments and compass adjusters. In fact, John Enos Hand, the company founder, is recognised as the first man in America to adjust a compass aboard an iron ship. The Hand Company built navigational equipment for all varieties of floating vessels, and operated a chain of retail outlets with “service stations” in numerous port cities, including Baltimore and New Orleans, until 1956. Service stations sold Hand instruments as well as other nautical paraphernalia and provided compass adjusting services. Additionally, John E Hand and his two sons, John L Hand and Bartram Hand, were inventors in their own right who patented design improvements for numerous instruments that were employed in the company’s work. Commercial and private contracts dominated the firm’s business until the late 1930s when the United States military began preparations for World War II. Although the Hand Company never completely abandoned its involvement with private industry, after World War II, military contracts monopolised their business. The Company obtained contracts with the Navy, Coast Guard and Marines to develop new instruments, and to build military-engineered nautical equipment. Of note are the wrist compass, developed for the Navy beginning in the 1950s, and the Mark VII Model 5 Navy Standard Binnacle. Although it moved numerous times, the Hand Company headquarters and factory remained in the Delaware Valley, occupying several buildings in Philadelphia and southern New Jersey. Maintaining its central office in Philadelphia well into the 1900s, the factory was moved to Atco, New Jersey around the turn of the twentieth century and subsequently to Haddon field, New Jersey. It moved one last time in the 1960s to Cherry Hill, New Jersey. In 1997, California-based Sunset Cliffs Merchandising Corporation purchased the Hand Company and all its assets for $100,000.

This small barrel looks well used. Unfortunately, the inscription on the barrel is indecipherable so its story is a mystery. However, the bungholes on the side are a clue that it was once used for storing liquid, likely to have been liquor. Barrels have been used over many centuries for transporting and storing a wide range of dry and liquid goods. They are made by tradesmen called coopers, who use heat and steam to bend and shape the wood to suit the work in hand. They add metal reinforcing, handles, spouts and suchlike, to complete they process. Their produce also includes buckets, casks and tubs. Ships transported bulk liquor in their cargo, stored in wooden barrels. The barrels' round shape allowed them to be easily moved by rolling them into place. The body's shape gave the barrels added strength and the iron bands helped the wooden sheaves stay in place. The tops and bottoms allowed for easy grip. The bungholes gave access to government representatives, who would sample the contents, measure the alcohol percentage, and charge the appropriate duty or tax; the process was called Ullaging and the instrument they used was a Hydrometer. Hundreds of barrels of cement were imported into Warrnambool in the late 19th century for the construction of the Warrnambool Breakwater. Barrel-shaped concrete blocks are still visible at shipwreck sites such as on the LOCH ARD wreck, which carried cement among its cargo.This small barrel is representative of 19th century containers used for transportation and storage of liquid such as liquor. It is a historic shape that is still used in modern times.Barrel; wooden barrel, cylindrical shape with metal bands or ribs for reinforcement. The side has two bungholes; one has a bung or stopper.

In 1885 Julius Pitrat of Gallipolis, Ohio, patented the first computing scale. Six years later, Edward Canby and Orange Ozias of Dayton, Ohio, purchased Pitrat's patents and incorporated The Computing Scale Company as the world's first computing scale vendor. And four years after that, The Computing Scale Company introduced the first automatic computing scale In 1911. the Computing Scale Company merged with the International Time Recording Company and Tabulating Machine Company to form the Computing-Tabulating-Recording Company, a business that was renamed IBM in 1924. An early example of a hanging clock face scale patented in October 1897 and made by a company that pioneered the first computing scales used in retail businesses.

The first spring balance in Britain was made around 1770 by Richard Salter of Bilston, near Wolverhampton. He and his nephews John & George, founded the firm of George Salter & Co., still notable makers of scales and balances, who in 1838 patented the spring balance. They also applied the same spring balance principle to steam locomotive safety valves, replacing the earlier deadweight valves. https://en.wikipedia.org/wiki/Spring_scale Today, spring scales are very popular with recreational fishers. The ability to weigh things reasonably accurately with a small inexpensive apparatus allowed for the exact weight of items to be ascertained. However, it was not accurate enough to weigh small amounts in ounces or grams.Scale. Has ring for hanging, spring and hook device for weighing.

This handheld portable pendulum quadrant scale was used to weigh small paper items such as letters and documents, powdered chemicals or metals like gold, and animal fleece samples. This mechanical scale can weigh up to a maximum of 10 ounces, which is about 285 grams or one-and-a-half cups of brown sugar. The operator holds the scale’s ring and connects the item to be weighed onto the wire clip. The weight of the item causes the pendulum to pivot, and the scale measures the weight of the object, indicated by the arrow. This scale belonged to Dr William Roy Angus and is now part of Flagstaff Hill’s comprehensive W.R. Angus Collection, donated by the family of Dr W R Angus, 1901-1970, surgeon and oculist. The W.R. Angus Collection: - The W.R. Angus Collection includes historical medical equipment, surgical instruments and material belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) and 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. It includes historical medical and surgical equipment and instruments from the doctors Edward and Thomas Ryan of Nhill, Victoria. Dr Angus married Gladys in 1927 at Ballarat, the nearest big city to Nhill where he began as a Medical Assistant. He was also Acting House surgeon at the Nhill hospital where their two daughters were born. During World War II He served as a Military Doctor in the Australian Defence Force. Dr Angus and his family moved to Warrnambool in 1939, where Dr Angus operated his own medical practice. He later added the part-time Port Medical Officer responsibility and was the last person appointed to that position. Both Dr Angus and his wife were very involved in the local community, including the planning stages of the new Flagstaff Hill and the layout of the gardens there. Dr Angus passed away in March 1970.This letter scale is the only one of its type in our collection. It is an example of objects belonging to Dr. W. R. Angus, 1901-1970, surgeon and oculist. 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 includes historical medical objects that date back to the late 1800s.Letter scale, a handheld quadrant fixed pendulum scale made from silver-plated metal. This small weighing instrument is shaped like a quarter-circle with a metal ring, a fixed pendulum counterweight and a decorative pivoting arrow indicator. A hanger clip is attached to a short arm of the scale. Measurements are embossed on the arc of the circle, labelled in ounces (oz) and ranging from 0 to 10 at unequal distances apart.

Galvanometers are an instrument used for detecting and measuring electric current. They had a magnetic needle moved by the magnetic field produced by coils carrying the current to be measured, and the earth's field had to be taken into consideration. They were used to detect current in either direction in telegraphy systems, and to test equipment.Post Office Galvonometer. A hinged polished timber case with three brass terminals at the top, and ring (handle) and a dial (0 to 70) with an indictor needle. The opened box reveals wires leading to the terminals with two compartments covered in blue woven material (possibly silk).telegraph works, galvonometer, scientific instruments

An induction coil consists of two coils of insulated copper wire wound around a common iron core. One coil, called the primary winding, is made from relatively few (tens or hundreds) turns of coarse wire. The other coil, the secondary winding, typically consists of many (thousands) turns of fine wire. An electric current is passed through the primary, creating a magnetic field. Because of the common core, most of the primary's magnetic field couples with the secondary winding. The primary behaves as an inductor, storing energy in the associated magnetic field. When the primary current is suddenly interrupted, the magnetic field rapidly collapses. This causes a high voltage pulse to be developed across the secondary terminals through electromagnetic induction. Because of the large number of turns in the secondary coil, the secondary voltage pulse is typically many thousands of volts. This voltage is often sufficient to cause an electric spark, to jump across an air gap separating the secondary's output terminals. For this reason, induction coils were called spark coils. The size of induction coils was usually specified by the length of spark it could produce; an '8 inch' (20 cm) induction coil was one that could produce an 8 inch arc. (http://en.wikipedia.org/wiki/Induction_coil)A metal and plastic object on a timber stand. In an induction coil the distance between the plates is often used to measure the voltage of the spark since the air breaks down at 30 000 volts per centimetreballarat college of advanced education, scientific instrument, induction coil, scientific instruments, electricity
