The barometer was either made or sold by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments. Thomas Gaunt photograph was included in an album of security identity portraits of members of the Victorian Court, Centennial International Exhibition, Melbourne, 1888. (See below for further details.) Admiral Fitzroy Pattern Barometer History: The stick mercury barometer was named after Admiral Robert Fitzroy of the Royal Navy (1805-1865) for his detailed instructions on how to interpret the weather, which were included with the instrument. Fitzroy was the captain of the HMS Beagle, also 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 that was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. In the original sale catalogue for Gaunt's, the item is described as "Gaunt's Fitzroy Barometers" and it was priced from 25/- to ₤9.9s. History of Thomas Gaunt: Thomas Gaunt established Melbourne's leading watchmaking, optical and jewellery business during the second half of the 19th century. Gaunt arrived in Melbourne in 1852, and by 1858 had established his own business at 14 Little Bourke Street. Around 1869 he moved to new premises in Bourke Street on the corner of Royal Arcade. Gaunt's shop quickly became a Melbourne institution. Gaunt proudly advertised that he was 'The only watch manufacturer in the Australian colonies'. While many watches and clocks may have had Gaunt's name on the dial, few would have been made locally. Gaunt did make some watches for exhibitions, and perhaps a few expensive watches for wealthy individuals. Gaunt's received a telegraph signal from Melbourne Observatory each day to correct his main clock and used this signal to rate and repair ship's chronometers and good quality watches. His main horological manufacturing was directed at turret clocks for town halls, churches and post offices. These tended to be specific commissions requiring individualised design and construction. He made the clock for the Melbourne Post Office lobby, to a design by Government Astronomer Robert Ellery, and won an award at the 1880-81 Melbourne International Exhibition for his turret clock for the Emerald Hill Town Hall. He became well known for his installation of a chronograph at Flemington Racecourse in 1876, which showed the time for the race, accurate to a quarter of a second. The firm also installed the clockwork and figures for Gog and Magog in the Royal Arcade. Thomas Gaunt also developed a department that focused on scientific instrumentation, making thermometers and barometers (from imported glass tubes), telescopes, surveying instruments and microscopes. Another department specialised in electroplating for trophies, awards and silverware, and the firm manufactured large amounts of ecclesiastical gold ware and silverware, for the church including St Patrick's Cathedral. There are no records that disclose the number of employees in the firm, but it was large enough for Gaunt to hold an annual picnic for the watchmakers and apprentices at Mordialloc from 1876; two years previously they had successfully lobbied Gaunt to win the eight hour day. Gaunt's workforce was reportedly very stable, with many workers remaining in the business for 15 to 30 years. Gaunt's wife Jane died on September 1894, aged 64. They had one son and six daughters, but only three daughters survived to adulthood. Two became nuns at the Abbotsford Convent and one daughter, Cecelia Mary Gaunt (died 28 July 1941), married William Stanislaus Spillane on 22 September 1886 and had a large family. Gaunt died at his home in Coburg, Victoria, leaving an estate valued at ₤41,453. The business continued as T. Gaunt & Co. after his death. 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 scientific equipment that Thomas Gaunt expanded his horology business into producing. Further social significance lies in the fact that Robert Ellery, the Government Astronomer who designed the local version of the barometer, had a direct connection with the Melbourne Athenaeum founded in 1839 as the Melbourne Mechanics' Institution. Its purpose was "the diffusion of literary, scientific and other useful information". There are also records of a T Gaunt as a subscription and committee member of this the Athenaeum organisation during the 1870s and 1880s which may be Thomas Gaunt, unfortunately still unverified.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), cleaning brush with printed instructions for interpreting information given by the gauge affixed to left and right face of instrument.

In 1913, Mark Cowley Lidwill designed a machine for the purpose of mechanical or insufflation anaesthesia. The Lidwill machine was a portable machine weighing 7kg that could easily be packed into two small bags. The machine involved compressed air being delivered to an ether vaporiser. An ether/air control device allowed varying concentrations of ether to be delivered. The ether vaporiser could be immersed in hot water to prevent cooling and the ether temperature was measured. From the vaporiser, the ether/air mixture went through a trap bottle, then to a crude mercury blow-off valve and subsequently to the patient.Large leather suitcase style bag divided into two levels containing and insufflation anaesthesia machine.insufflation, mark cowley lidwill, thoracic surgery, positive pressure

This work forms part of the collection assembled by the historian Dorothy Rogers, that was donated to the Kew Historical Society by her son John Rogers in 2015. The manuscripts, photographs, maps, and documents were sourced by her from both family and local collections or produced as references for her print publications. Many were directly used by Rogers in writing ‘Lovely Old Homes of Kew’ (1961) and 'A History of Kew' (1973), or the numerous articles on local history that she produced for suburban newspapers. Most of the photographs in the collection include detailed annotations in her hand. The Rogers Collection provides a comprehensive insight into the working habits of a historian in the 1960s and 1970s. Together it forms the largest privately-donated collection within the archives of the Kew Historical Society.'Yarra Bluffs' was the home of George Henry (1831-1906) and Allegra Charnock Mott (1831-1905), newspaper proprietor (and also a friend of John Inglis, father of Kew doctor, Edgar Inglis, who bought land adjacent to this property in the 1890s). Walter was a son who drowned in the Yarra in a swimming accident January 2, 1890.
