Instrument - Aneroid Barometer
An aneroid barometer is an instrument used for measuring air pressure as a method that does not involve liquid. Invented in 1844 by French scientist Lucien Vidi, the aneroid barometer uses a small, flexible metal box called an aneroid cell (capsule), which is made from an alloy of beryllium and copper. The evacuated capsule (or usually several capsules, stacked to add up their movements) is prevented from collapsing by a strong spring. Small changes in external air pressure cause the cell to expand or contract. This expansion and contraction drives mechanical levers such that the tiny movements of the capsule are amplified and displayed on the face of the aneroid barometer. Many models include a manually set needle which is used to mark the current measurement so a change can be seen. This type of barometer is common in homes and in recreational boats. It is also used in meteorology, mostly in barographs and as a pressure instrument in radiosondes.5 inch Aneroid barometer on wooden basebarometer, aneroid -

Surveyor's Pocket Altimeter, c 1940
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.

Photograph - Royal Australian Survey Corps Aerial Surveys, c1980
This is a set of nine photographs of technicians from the Royal Australian Survey Corps operating aerial surveys equipment c1980s. In photo .1P, CPL Steve Gloster was operating a RC10 air survey camera mounted in an Australian Army Pilatus Porter aircraft. The Wild RC10 super wide-angle air survey cameras were first introduced in 1971, were equipped with virtual distortion free lenses for supplementary, spot and special photography. In photo .2P, Roger Rees was operating Air Profile Recorder (APR) equipment. it was possibly taken during OP NERVOSE 84, sometime between June – August 1984 when based in Ngukurr, Northern Territory. The APR was operated at this time in unison with an RC10 camera. In 1963 the Royal Australian Survey Corps introduced the radar airborne profile recorder (Canadian Applied Research Ltd, Mark V, Airborne Profiler Recorder) was introduced for 1:100,000 mapping to replace terrain heighting by aneroid barometry. Later in 1974-1975, the Australian developed WREMAPS II airborne laser terrain profile recorder was introduced. In photo .3P, Neil Jones appears at the door of Airsearch Beechcraft Queen Air aircraft, Registration / Serial VH-MWX. This aircraft was typically used by RA Svy on air survey operations flying mission with Aerodist, APR and RC10 camera equipment. The Australian Army’s Pilatus Porter (short take-off and landing turbo propeller) was also equipped with a Wild RC10 aerial mapping camera for identification photography. The Pilatus Porter was also used on RA Svy’s map field checking operations. Photo .9P was taken at a survey station at an unknown location. In this photo an Australian Army Kiowa Light Observation Helicopter (LOH) is supporting a field survey party undertaking Magnavox AN/PRR-14 portable Doppler satellite observations. The satellite receiver’s antenna is plumbed over the survey ground mark surrounded by white plastic panels. The panels were used to identify the survey station on aerial photography. Introduced in 1974–1975, the Magnavox AN/PRR-14 portable Doppler satellite (US Navy Navigation Satellite System – TRANSIT) receivers and computing system provided independent three-dimensional point positions anywhere in the world, anytime, in any weather accurate to about 1.5metres with precise satellite ephemerides. The Bell OH-58 Kiowa LOH was a family of military helicopters used for observation, utility, and direct fire support. It was identified by RA Svy in the mid-1970s that considerable time was lost in replacing unserviceable remote equipment by road. Therefore Aerodist operations (pre-dating satellite receiver operations) were fully supported by Army’s Kiowa LOH aircraft.

Instrument - Marine Telescope, 1870-1880
This telescope was amongst various items collected from a sea dive in Port Phillip Bay. The diver was the caretaker of the Port Lonsdale Lighthouse, who dived on various wrecks in the bay during the 1960's. After the caretaker's death, his son sold off many of the shipwreck artefacts. The telescope was purchased from the caretaker's son in the 1990's by a previous owner of the Marine Shop, Queenscliff, Victoria. John Browning was particularly well known for his scientific advances in the fields of spectroscopy, astronomy, and optometry. Between 1856 and 1872, Browning acquired provisional patents for designs of numerous scientific instruments. He was also the recipient of an award at the 1862 International Exhibition held in London. Also recognised for his temperature-compensated aneroid barometer. Browning's scientific instruments were used in physics, chemistry, and biology. The products he designed and manufactured included spectroscopes, telescopes, microscopes, barometers, photometers, cameras, ophthalmologist, and electrical equipment such as electric lamps. John Browning was born around 1831 in Kent, England. His father, William Spencer Browning, was a maker of nautical instruments. John Browning's great-grandfather was also an instrument maker as well as John’s brother Samuel Browning of the firms Spencer & Browning and Spencer, Browning & Rust, who also manufactured navigational instruments. The latter firm was in operation in London from 1784 to 1840 and was succeeded by the firm of Spencer, Browning & Co. John Browning initially intended to follow the medical profession and entered Guy's Hospital, a teaching hospital and a school of medicine. Despite having passed the required examinations, however, he abandoned his plans. Instead, he apprenticed with his father, William Spencer Browning. At the same time, in the late 1840s, he was a student attending the Royal College of Chemistry several days per week. By the early 1870s, practical optics had become John Browning's primary interest, and he listed his occupation as an optician on the census records from 1871 to 1901. He was well known among London's ophthalmic surgeons for his various ophthalmic instruments. He had a large part in reforming the art of crafting spectacles. Other achievements were as an author of the book, How to Use Our Eyes and How to Preserve them by the Aid of Spectacles. Published in 1883, the book included thirty-seven illustrations, including a diagram demonstrating the anatomy of the eye. In 1895, he was one of the founders of the "British Ophthalmology" the first professional organisation for optometry. He was not only its first president but also registered as its first member so many considered him to be the first professional optometrist. Other professional organisations he belonged too was as a member of “The Aeronautical Society of Great Britain”. In 1871 constructing the first wind tunnel located at Greenwich Marine Engineering Works. He was also a member of other scientific organisations, such as the “Microscopical Society of London”, the “Meteorological Society”, and the “Royal”. Then in 1908 the company of W. Watson & Son, opticians and camera makers, took over John Browning's company since 1901 John Browning had been semi-retired but in 1908 he fully retired and moved to Bournemouth in Hampshire. He died in Cheltenham, Gloucestershire in 1925.The telescope is significant for its association with one of the world’s leading scientific instrument makers and inventor of the 19th and early 20th century. It is believed the donation came off a wreck either in Port Philip Bay or between Point Lonsdale and the Nepean Heads making it a significant maritime historical artefact. Its provenance is good given it was taken off a wreck in this area by the Point Lonsdale lighthouse caretaker. Examples of John Browning's telescopes because of their scientific and historical importance are highly valued by collectors.Marine style single draw brass telescope with a sunshade. The single draw has no split and the second cartridge is held in a long brass tube within the single draw, mounted from the objective end. The eyepiece is flat and at the end of the first draw in a very faded engraving that is believed to read "John Browning, 63 Strand, and should read London under the word strand but this is hard to establish given the engravings condition. This interpretation of the engraving has been arrived at by examination of other John Browning telescope engraving examples."John Browning, engraved to the first tube in copper plate style "63 STRAND" Engraved under in capital textflagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, shipwreck coast, shipwreck artefact, port phillip bay, port lonsdale lighthouse, wreck, 1960’s diver, queenscliff marine shop, john browning, telescope, spectroscopy, optometry, scientific instruments, william spencer browning, optician, navigational instrument, microscopical society of london, aeronautical society, marine technology -

The afternoon sun was lowering towards a heavy bank of clouds hanging still and sullen over the Medite-rranean. A mistral was blowing. The last yellow rays shone fiercely upon the towering coast of Corsica, and the windows of the village of Olmeta glittered like gold. There are two Olmetas in Corsica, both in the north, both on the west coast, both perched high like an eagle's nest, both looking down upon those lashed waters of the Mediterranean, which are not the waters that poets sing of, for they are as often white as they are blue; they are seldom glassy except in the height of summer and sailors tell that they are as treacherous as any waters of the earth. Neither aneroid nor weather-wisdom may, as a matter of fact, tell when a mistral will arise, how it will blow, how veer, how drop and rise, and drop again. For it will blow one day beneath a cloudless sky, lashing the whole sea white like milk, and blow harder to-morrow under racing clouds.Ill, p.344.fictionThe afternoon sun was lowering towards a heavy bank of clouds hanging still and sullen over the Medite-rranean.
