E. R. Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

This instrument was used by Dr Fritz Duras (1896-1965), who moved to Australia from Germany in 1937. As his father was Jewish, Duras was forced to leave Germany, and came to Australia to take up a post as director of physical education at Melbourne University. This instrument was part of a collection of instruments given to his son-in-law, Dr Michael Kloss, who was an obstetrician. Dr Kloss subsequently donated the collection to the College, after using many of the instruments in his own practice. Metal uterine catheter.

Optometrists are trained to examine eyes and prescribe visual aids such as spectacles. The optometer pictured in the media section of this document dates from the 1800s. The optometer was used with various lenses to determine the refraction of the eye. Refraction means the extent to which light is bent by an individual's eye. The result can determine how short-sighted or long-sighted they are, and the strength of spectacles required. In the second half of the 1800s, ophthalmologists also devised instruments to measure the separate components of vision. Dr Jules Badal developed the pictured instrument in 1876. It was based on an optometer invented by William Porterfield in 1759. The brass stands look as though they were made for an optometer to be table mounted, with heavy brass stands and designed to hold a cylindrical object securely as would be required by an optometer. Stands appear to have been very well made and very early probably early to mid 19th Century by a well known scientific instrument maker given there are no inscriptions or marks to indicate the time period made or maker it is difficult to assume significance to these items at this point in time as well as the items are incomplete.The brass stands believed to be for mounting an early Optometer an (ophthalmic instrument) Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, stands for scientific instrument

Bushfire behaviour is influenced by many factors including temperature, relative humidity (RH), forest type, fuel quantity and fuel dryness, topography and even slope. Wind has a dominant effect on the Rate of Spread (ROS), as well as fire size, shape and direction. Temperature and relative humidity have major impacts on fuel dryness and therefore upon the availability of fuel for combustion. The amount of fine fuel available can increase rapidly from nearly zero when fuel moisture content is more than 16% after rain or a heavy morning dew, to many tonnes per hectare as fuel dries out later in the day and the moisture content drops below 9%. This explosive escalation in the amount of available fuel can happen over a few hours on hot and windy days. A sling psychrometer is a simple device for determining air temperature and relative humidity. It contains two thermometers, one of which is covered with a wick saturated with ambient temperature liquid water. These two thermometers are called dry bulb and wet bulb. When the sling psychrometer is spun rapidly in the air, the evaporation of the water from the wick causes the wet bulb thermometer to read lower than the dry bulb thermometer. After the psychrometer has been spun long enough for the thermometers to reach equilibrium temperatures, the unit is stopped, and the two thermometers are quickly read. A psychrometric scale on the side of the instrument is then used to convert the dry bulb temperature TDB and the wet bulb temperature TWB into humidity information. The wet bulb temperature is approximately equal to the adiabatic saturation temperature. The thermometers fold back into the plastic handle when not in use.
