An Octant is a doubly reflecting navigation instrument used primarily by sailors to measure the angular distance between two visible objects and was a forerunner of the sextant. The name comes from the Latin octo, or “one-eighth of a circle,” for the Octant’s arc which spans 45°, or one-eighth of a circle. The primary use of an Octant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation. The estimation of this angle is known as sighting or shooting the object, or taking a sight. The angle, and the time when it was measured, can be used to calculate a position line on a nautical chart (latitude), for example, sighting the Sun at noon or Polaris at night (in the Northern Hemisphere) gives an angle by which the latitude can then be estimated. Sighting the height of a landmark on land can also give a measure of distance. History: The principle of the Octant as an instrument to measure ones latitude was first implemented around 1742-present but was superseded by the improvement of the octant to a sextant, a very similar instrument, better made and able to measure bigger angles 120°, allowing the measurement of Luna distances to give longitude when used with an accurate chronometer. The sextant started to appear around 1730 and had been attributed to by John Hadley (1682–1744) and Thomas Godfrey (1704–1749), but reference to the sextant was also found later in the unpublished writings of Isaac Newton (1643–1727). Earlier links can be found to Bartholomew Gosnold (1571–1607) indicating that the use of a Sextant for nautical navigation predates Hadley's implementation. In 1922, the sextant was modified for aeronautical navigation by Portuguese navigator and naval officer Gago Coutinho. Henry Hemsley was a lesser-known instrument maker and optician working in London in the late 17th and early 18th century. However, it should be noted that there were two Henry Hemsley opticians and instrument makers around this period. (Henry Hemsley 1, 1786-89, who had premises at 85 Fleet St London and Henry Hemsley 2, 1828-56), whose workshop was at 135-138 Radcliff Highway London. Therefore, based on the inscribed workshop address Henry Hemsley 2 is responsible for making this example.The octant is representative of its type and although not fully complete it demonstrates how 18th and 19th-century mariners determined their latitude on a chart to navigate their way across the world's oceans in the 18th and 19th century. It also demonstrates the skill and workmanship of the early instrument makers that operated from London at this time and provided most of the navigational instrumentation use by commercial and military navies of the time.Octant, ebony wooden frame and handle.

This meter belonged to the State Electricity Commission of Victoria. This meter measured the power used by all the houses in Mount Beauty and provided an inked one month period chart. This information was used to quantify and pay for the power consumption to the Transmission and Generating Department from the Distribution Department which then went on to bill local consumers.The State Electricity Commission of Victoria constructed the Kiewa Hydro Electric Scheme from the late 1930's to the 1960's. The construction towns of Bogong and Mt Beauty used electricity which was measured by this meter resulting in billing customers for the power they used.Black box with black painted wooden frame top and bottom screwed on holding clear glass at the front so that the instruments can be seen.

An aneroid barometer is an instrument used for measuring pressure without the use of a 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 and responds to changes in air pressure.An example of a widely used type of barometer.A brass aneroid barometer with a white face.Manufactured by C.

This book, ‘The Practical Measurer’, by Alexander Peddie, is subtitled ‘Tradesman and Wood Merchant’s Assistant’. It is a tradesman’s guide to measuring and contains many tables of measurement. The inscription in the front of the book shows that it belonged to Thomas Osborne and that he obtained it from D. McColl who is identified in the inscription as the Chief Engineer of the steam ship, ‘Julia Percy’. There is a record of a Donald McColl owning the vessel ‘Mimmie Dyke’ and sailing it to Mauritius in 1856 and there is also a record of the death of a Donald McColl in 1880 so these two facts may refer to the D.McColl mentioned by Thomas Osborne (especially as he refers to him as ‘poor old Mr D. McColl’). Thomas Hamilton Osborne was born in Port Fairy in 1851. He had a lifelong interest in ships and in Warrnambool was the Secretary and then Manager of the Western Steam Navigation Company for 16 years. Osborne wrote many articles with nautical themes using the nom-de-plume of ‘Sliding Gunter’ and had a great love of, and interest in, the ship, ‘Julia Percy’ and when he died in 1902 his body was put on board the ‘Julia Percy’ and he was buried at sea. The ‘Julia Percy’ (built 1876) was a well-known steamship on the western Victorian coast for many years. Later it plied the Queensland coast, saw service in West Australian waters, was renamed the ‘Leeuin’ and was used as a coal hulk until it was scuttled in 1935. The signature in the book of T. Hyland may indicate that he donated the book to the Warrnambool and District Historical Society. This book is of prime importance because:- 1. As a book printed in 1863 it is of antiquarian interest. 2. The connection with Thomas Osborne is of key interest as he was a notable figure in Warrnambool’s 19th century history, especially in maritime circles. 3. The connection with the ship, ‘Julia Percy’, is of particular interest as it was a prominent ship in Warrnambool’s maritime history. This is a hard cover book of 448 pages with brown and gold leather binding on the spine and cover edges and a brown and tan mottled pattern cover. The book has a Preface, a Contents page, information on how to measure all types of solid figures and how to measure work involved in the various trades – masons, carpenters, painters, glaziers, plumbers etc. It also has two Appendices with information on the measurement of sawn timber. The text has many tables and diagrams. The first page has a handwritten inscription in black ink and the back pages have some mathematical calculations written in pencil and a mathematical problem with its solution written in ink.
