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. All parts of the float and eight weights are inscribed with Serial Number “14674” The float stem is stamped "SIKE'S IID 51o” Calibrator, "LONG LITTLE TOWER ST LONDON" The weights are numbered individually ”20”, “30”, “40”, “50”, “60”, “70”, “80” or “90” Each weight in inscribed; symbol “(J L) [inside an ova, with textured background]” The thermometer inscribed: “LOFTUS OF LONDON”flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, measuring instruments, customs tax, weighing instrument, sike’s hydrometer, calibrator long of london, loftus of london instrument maker, loftus, j long, sikes hydrometer, scientific instrument, pressure measurement, measuring instrument, ullage tool, customs, excise duty, tax, alcohol content, proof, calibrate, standard weights and measures, tariff, scientific instrument makers, specific gravity, liquid density, alcohol testing, technology, alcohol measurement, proof spirit, wine and spirits merchants, local business, brass measuring instrument, port fairy, customs office, port fairy customs, joseph long, instrument maker

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. On the opposite thin edge of the float: “N20.373”, “SIKES”, “I P % II O” (in ornate capitals). Each weight has s unique number, and the same serial number “20373”.flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, sikes hydrometer, scientific instrument, pressure measurement, measuring instrument, ullage tool, customs, excise duty, tax, alcohol content, proof, calibrate, standard weights and measures, tariff, kasner & moss, scientific instrument makers, specific gravity, liquid density, alcohol testing, technology, alcohol measurement, proof spirit, wine and spirits merchants, local business, brass measuring instrument, k m lynch, giffen russell, harry lynch
