Henry Sutton is a talented world-wide accepted inventor with inventions relating to the telephone, photography, wireless, cars, motorcycles, and bicycles as well as many more inventions. Henry was also one of four brothers that ran the Sutton's Music Store after the death of their Father Richard Sutton. Henry Sutton taught Applied Electricity at the Ballarat School of Mines in 1883 to 1886.Folder containing information about Henry Sutton, the Phonola, Ballarat Mechanics Institute, Microscopical Studieshenry sutton, phonola, microscopical studies, ballarat mechanics institute, art

Microtome for cutting resin embedded tissues for electron microscopy. In 1957 a modified hodge microtome redesigned and built by H.A. Waters of the Melbourne University Department of Physics was acquired. The Waters microtome is of thermal expansion type - the rod “A” is heated and by expansion pushes the resin block forward by a fraction. It is mounted on a long cast iron base. The movement of the block is eccentric drawing the specimen away from the knife after cutting, The glass knife ‘B’ is adjustable by means of a modified microscope column screws ‘C’. The microtrome is driven by a continuous action electric motor mounted on the common base. Hand cutting can also be done. The cutting was controlled by viewing through a Leitz Binocular microscope mounted on the same base. The original microscope was subjected to nine modifications by Dr S Weiner from whose PhD Thesis (1962) ‘Electron Microscopical Studies of the Liver’ this information was obtained. (text provided by Professor H Attwood) Microtome made of metal and enamelled in light blue. Components are identified by the use of stick on labels. The microtome is mounted on a long cast iron rectangular base and has an electrical cord for connection to a power point.Plaque on back: “Pathology Department, University of Melbourne Serial No. 0091.

Geological specimen - Green Feldspar (orthoclase)

Feldspar, derived from the German word feldspat, is a group of minerals which is the most common mineral group found on Earth, making up more than half of the planet's crust. The major rock-forming minerals in the Feldspar group include albite, anorthite, orthoclase and microcline. (Mindat, Feldspar Group). Orthoclase is part of the Feldspar Group subgroup, Alkaline Feldspar, which are known to be poor in calcium, and mostly rich in potassium. It is further also considered to be a K Feldspar, a subgroup of Alkaline Feldspar that are Potassium-dominant with variable crystal symmetry and Al-Si ordering state. Orthoclase are most commonly Colorless to white, Greenish white, Grayish yellow, or Pale pink and transparent to translucent with slightly pearly cleavage. The mineral rates at a 6 on the Mohs Hardness Scale. (cannot be scratched with a knife, but scratches glass with difficulty). The stronger green colour of this particular specimen is distinctive to the Broken Hill region (where it was found), and due to a small amount of lead. (BB) Its qualities find it misidentified at times as as microcline variety amazonite. Broken Hill is one of the world’s richest lead-zinc-silver deposits. The huge, 300-million-tonne orebody was discovered in 1883 and the superb mineral specimens attract collectors from around the world. (Australian Museum, Minerals from Australia: Australian mining regions)While feldspar is not by any means rare, this particular specimen has qualities distinctive to the Broken Hill mining district, with these properties leading at times to the mineral's misidentification. This creates potential for further study and identification of these mineral deposits through methods such as microscopic twinning, or using the position of certain d values in XRD patterns to calculate the degree of disorder of a K-feldspar, as discussed on the Mindat website (Mindat.com, Orthoclase:About Orthoclase). This specimen is part of a larger collection of geological and mineral specimens collected from around Australia (and some parts of the world) and donated to the Burke Museum between 1868-1880. A large percentage of these specimens were collected in Victoria as part of the Geological Survey of Victoria that begun in 1852 (in response to the Gold Rush) to study and map the geology of Victoria. Collecting geological specimens was an important part of mapping and understanding the scientific makeup of the earth. Many of these specimens were sent to research and collecting organisations across Australia, including the Burke Museum, to educate and encourage further study.A solid small aluminosilicate mineral composition which is primarily pale green and blue-grey in colour with traces of beige and white throughout. Note: green plumbian orthoclase (aka green feldspar) is an indicator mineral for the Broken Hill style lead-zinc deposits.N/Abroken hill mine, geological specimen, minerology
