The Plane Table Alidade was used as the sighting Instrument in the production of historical manual hand drawn maps. A Plane Table Board mounted on a tripod is levelled and the Alidade is placed on the table with the vanes perpendicular to the it. Each sighting vane has a central thread lined up on the target and the angle to that target point is then drawn on the map sheet using the beveled fiducial edge. Plane Table Surveying is used as a quick method where less accuracy is required or needed. Plane table Surveying is a relatively portable and inexpensive method and was used extensively before the advent of sophisticated surveying instruments. The photo at 6489.2 is an Australian Army Survey Corps Party using a Plane Table Alidade in Syria during WWII.Two Plane Table sighting instruments (Alidade) used for historical manual map making housed in wooden transit boxes. A brass instrument with folding sights at each end and a beveled fiducial edge in one edge. The front sight is the object vane and the rear sight is the sight vane. There is a sliding arm attached to the base to draw parallel lines to the fiducial edge. Very slight differences in model between these two instruments.First Instrument, "ER Watts and Son, London, 1938, MkII, Box Label 423. Second Instrument - R.

A slide rule is an instrument which is used to carry out mathematical calculations. William Oughtred is credited with its invention in 1621, however many others including Isaac Newton have made improvements or modifications over the years. From 1625 to 1800 there were approximately 40 different styles brought forward. with the following 100 years sees over 250 designs created.There have been different versions and modifications to suit scientific, mathematical and engineering requirements. It is interesting to note that many of the buildings of the 19th and 20th centuries have been designed with the use of slide rules. Their use has declined in the last 25-30 years with the advent of computers and specialist calculators.While not directly linked in any way to the history of Warrnambool, this slide rule would have been a item in use by students doing maths at upper secondary level as well as other applications which would make it a familiar object to many people.Coated bamboo with sliding metal framed glass panel or cursor .

The Heliograph MkV is a fascinating piece of historical surveying and communications equipment. It was primarily used for visual signaling by reflecting sunlight with a mirror to send coded messages over long distances. This method was primarily useful in remote areas where other forms of communication were not available. The MkV model, specifically, was widely used by the British Army and other military forces from around 1906 until the mid 1960s. It remained in use with the Australian Army Survey Corps until the mid 1980s. The device typically included a 5 - inch mirror and was often mounted on a tripod for stability. Initially the instrument was used to communicate between survey stations using Morse code to coordinate their activities. Later when better forms of communication were available, they were used for precise angle alignment where the sunlight reflection from the mirror was targeted between the survey stations to give very accurate results. The MkV was relatively light weight and portable, making it ideal for use in the field. It could be setup and adjusted quickly. The heliograph had an adjustable mirror that could be tilted to reflect sunlight towards a distant receiver. Surveyors could align the mirror using a sighting device. Whilst it was primarily used by the Military it was also used in civil surveying particularly in the remote areas of Australia. The British Army Mark V version uses a flat round mirror with a small unsilvered spot in the centre. The sender aligned the heliograph to the target by looking at the reflected target in the mirror and moving their head until the target was hidden by the unsilvered spot. Keeping their head still, they then adjusted the aiming rod so its cross wires bisected the target, they then turned up the sighting vane, which covered the cross wires with a diagram of a cross, and aligned the mirror with the tangent and elevation screws, so the small shadow that was a reflection of the unsilvered spot hole was on the cross target. This indicated that the sunbeam was pointing at the target. If the sun was in front of the sender, its rays were reflected directly from this mirror to the receiving station. If the sun was behind the sender, the sighting rod was replaced by a second mirror, to capture the sunlight and direct it onto the main mirror to reflect it to the receiving station.. 1 Brish Army "Mance" Mk V A253 Heliograph has two 125mm diameter mirrors on a brass arm with targeting attachments.

This surgical instrument, known as a nasal septum, was donated to Flagstaff Hill Maritime Village by the family of Doctor William Roy Angus, Surgeon and Oculist. It is part of the “W.R. Angus Collection” that includes historical medical equipment, surgical instruments and material once belonging to Dr Edward Ryan and Dr Thomas Francis Ryan, (both of Nhill, Victoria) as well as Dr Angus’ own belongings. The Collection’s history spans the medical practices of the two Doctors Ryan, from 1885-1926 plus that of Dr Angus, up until 1969. Dr Angus and his family moved to Warrnambool in 1939 and purchased 'Birdwood in Koroit Street (now the location of the Police Station and ALDI), the previous home and medical practice of Dr John Henderson. Dr Angus was appointed on a part-time base as the Port Medical Officer in Warrnambool and held this position until the 1940s, when the position was no longer required. He was also a surgeon at the Warrnambool Base Hospital 1939-1942.This surgical instrument is significant for its connection with Dr W.R. Angus of Warrnambool. The W.R. Angus Collection is significant for still being located at the site it is connected with, Doctor Angus being the last Port Medical Officer in Warrnambool. The collection of medical instruments and other equipment is culturally significant, being an historical example of medicine, administration, household equipment and clothing from late 19th to mid-20th century. Dr Angus assisted Dr Tom Ryan, a pioneer in the use of X-rays and in ocular surgery. Surgical instrument, part of the W.R. Angus Collection.

This pH meter was made in 1946 by Cambridge Scientific Instrument Co. Ltd. in London. The company was founded in 1881 and the owner eventually became Horace Darwin, the youngest son of the famous scientist Charles Darwin. It is a portable version that can be used on-site in many different situations. A similar instrument was used by the Chemistry Department of what is now the University of Cambridge. The science of pH measurement began in the 1910s and was further developed in 1926. The pH meter is an electronic scientific instrument used to determine the pH measurements of a solution accurately; the amount of acid and alkaline in it This measurement can have many other applications helping to maintain the appropriate balance for a particular result. For example, it can measure the pH of pharmaceutical medications, soil, swimming pool water and hair shampoos. This Cambridge portable electronic pH instrument was made in 1946 by a company specialising in scientific instruments. It is an early example of much smaller devices used today in many different fields including medicine, and the preservation and conservation of shipwreck artefacts. Flagstaff Hill Maritime Museum and Village's Curator uses a pH meter today in the conservation process of a historic cannon that was recovered from the 1839 wreck of the vessel 'Children'.Scientific instrument, electric Cambridge Portable pH Meter in a polished wooden box with compartments, fold-out doors, and leather carry handle.
