Instrument - Barometer, Early 20th century
... weather gauge... scientific instrument weather forcasting instrument weather gauge ...A barometer is an instrument used for measuring atmosphere pressure thus determining weather changes.The first apparatus generally accepted as a barometer was that set up in Florence in 1644 by Evangelista Torricelli (1608–1647), a mathematician and physicist. Torricelli filled a glass tube with mercury, sealed it at one end, and inverted it with its open end in a dish of mercury. The level always fell a short way down the tube, then settled at a height of about thirty inches. He concluded correctly that the mercury column was sustained by the weight of the air pressing on the open surface of mercury, and further experiments convinced him that the space above the mercury in the tube was a vacuum. He noted that the level rose and fell with changing temperature, but he was unable to use his apparatus to measure variations in the weight of the atmosphere because he had not foreseen that temperature would affect the level of the mercury. News of this experiment circulated quickly among European scientists, who hastened to replicate the experiment. Torricelli's conclusions were not universally accepted because some disputed whether the air had weight, while both Aristotle and the Catholic Church denied the possibility of a vacuum. In France, the philosopher René Descartes (1596–1650) seems to have been the first person, probably in 1647, to attach a graduated scale to the tube so that he could record any changes attributable to the weather. At around this time Duke Ferdinand II of Tuscany organized the first short-lived meteorological network among scientists in other Italian cities, gathering observations of pressure, temperature, humidity, wind direction, and state of the sky.Theis barometer is an example of a household item from the early 20th century, used to determine the day's weather. The barometer is significant as an aid to human social, material and scientific development.Barometer, round, brass housing inset into carved wooden casing (lacquer mostly worn off).

Thermometer, Early 20th Century
A Storm Glass and Thermometer such as this one would be used in predicting or forecasting the weather. Farmers used predictions they read from their Storm Glass to prepare for stormy weather or for choosing a good time for planting or harvesting their crops. This could mean to them the difference between a good year and a year without income. This design has been in use since the early 1800’s. According to Admiral Fitzroy (who studied the storm glass and wrote instructions on its use) the liquid in the glass changes composition and appearance according to the direction of the air moving around it. He advised the user to disturb the contents once or twice a year by tipping it upside down and shaking it gently. Item is a good example of a barometer/thermometer that would have been in most homes and farms from the late 19th century and early 20th century. This item would have been massed produced at the time therefore easily available and quite cheap to purchase making this particular item not very significant as not associated with a historic person or property or with a known manufacturer or date.Storm Glass and Thermometer, commonly called a 'Cottage Barometer', mounted on a rectangular dark rectangle of wood, top corners rounded. The Storm Glass (or weather glass, or chemical weather glass) is suspended in a long oval shaped hole in the wood on left side, held in place at top and at bottom with 2 metal bands secured by nails. The glass of this gauge is hand blown, sealed at the top with another layer of glass. The watery fluid in the storm glass is opaque brownish colour with dark particles floating in it. (Storm glasses were usually filled with a variation of a mix of camphor, distilled water, ethyl alcohol and silver nitrate.) The alcohol thermometer is mounted on the right side of the wood, bulb resting in a hollow, attached at top and near base by 2 thin metal strips, with clover-leaf shaped ends, nailed into place. Over the bulb is nailed a metal guard with 3 ventilation slits cut into it. On left of thermometer is a scale, stamped into wood, 30 below zero to 130 above zero, in 2 degree intervals. A border of 2 thin parallel lines, with remnants of light coloured paint, is around the block of wood. On the reverse side, a metal plate is nailed to the top with a mounting hole in it. Impressed sideways along edge of barometer is "STORMY" "CHANGE" "FAIR". Across the top of the thermometer is a fleur de leis in the wood, and above this it is stamped "FAHRENHEIT". On right of the thermometer, stamped into the wood, is "BLOOD/HEAT", "SUMR/HEAT", "TEMPE/RATE", "FREEZ/ING". On the back of the wood, at the base, are remnants of a white sticker with "...111.73". Carved into the wood is "HOLLAND / AV". flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, barometer, cottage barometer, storm glass, thermometer, chemical weather glass -

Diary Extract - Trip to Bogong High Plains Xmas 1934 & DVD photos, original diary 1934
The Melbourne Women's Walking Club enjoyed bush walking as a hobby travelling to the north east of Victoria, using pack horses and camping on a 9 day hike. One of the woman, 'Bill' describes each day in detail - what they did, where they went and what they saw giving an insight into walking and the Bogong High Plains in the mid 1930's before the Kiewa Hydro Electric Scheme opened up the area. The diary mentions a photo being taken by Mr Blackwell on the 9th day, New Year's Eve 'from a lovely bush track from which, looking back at intervals we got our final glimpse of Fainter. 5 miles from from our destination'.Historic: This extract from the diary of 'Bill', a member of the Melbourne Women's Walking Club gives an insight into walking in the mid 1930's and describes the Bogong High Plains as it was then before it was opened up with a road built during the Kiewa Hydro Electric Scheme. It describes the area in summer including the flora & fauna, cattle grazing & cattlemen, the huts, the gauges set up by the State Electricity Commission of Victoria, the people working up there, the weather and the lifestyle of the walking group - their food, duties, swimming etc.. Six double sided typed photocopied yellow pages describing the Melbourne Women's Walking Club trip to the Bogong High Plains at Christmas in 1934.

Barometer, Given the plaque affixed to the instrument states Royal Arcade as the premises’ address it is assumed that the barometer was manufactured no sooner than1869
Stick mercury barometer, named after Admiral Robert Fitzroy of the Royal Navy (1805 - 1865) for his detailed instructions on interpreting the weather that are included with the instrument. Fitzroy was the captain of the Beagle, a weather forecaster to Charles Darwin and the second Governor of New Zealand. He developed many different types of barometers and was the first person to introduce the science of weather forecasting to the British Isles. A local manufacturer of scientific instruments, Thomas Gaunt, produced the barometer and it was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. Described as "Gaunt's Fitzroy Barometers" in the original sale catalogue, it was priced from 25/- to ₤9.9s. [See Miller, M., Gaunt’s Time, 2014]. Thomas Gaunt's business was originally located at 14 Bourke Street East from 1858. In 1869-1870 he moved to new premises in the Royal Arcade, Collins Street. Gaunt's business became an institution in Victorian Melbourne and Gaunt its leading clock maker. PROVENANCE According to official minutes the barometer was purchased by the Melbourne Athenaeum in 1874. In particular, at the March meeting of the General Committee the House Subcommittee was instructed to "obtain a Fitzroy or other reliable barometer" to be "fixed in the Reading Room". The 1874 Annual Report records the purchase at ₤3.10.0. The barometer is historically significant as an example of the work of Melbourne’s leading scientific instrument maker, Thomas Gaunt. The barometer has social significance as an example of the type of accoutrements provided by the committee of the Melbourne Athenaeum for the comfort of its members. Further social significance lies in the fact that Robert Ellery, the Government Astronomer, who designed the local version of the barometer, has a direct connection with the Athenaeum being a subscription member and committee member of the Athenaeum during the 1870s. There are also records of a T Gaunt as a subscription member of the Athenaeum during the 1870s and 1880s which may be Thomas Gaunt, however, this is yet to be verified. Stick mercury barometer known as the Admiral Fitzroy Barometer. It comprises an oblong wooden case with glass front panel, ornate pediment, barometer with bulb cistern (empty of fluid),printed instructions for interpreting information given by the gauge affixed to left and right face of instrument. Includes a thermometer. The barometer appears to be intact except for the turning knobs which are missing and the mercury in the tube which is not present. Whether the instrument could be restored to working order is unknown.
