Junker's inhaler of brown glass, shaped as a cylindrical bottle, with two curved metal tubes protruding from a metal cap. One tube is connected to a brown rubber tube that ends in double-barrelled hand bellows. On the right is a black vulcanite rubber mask, which is also connected to a brown rubber tube. Junker's inhalers are a "blow over" device, used with hand-held bellows to bubble air through liquid chloroform in the jar and through to the patient.Hand-written inscription on bellows.

Between 1867 and 1920, anaesthesia for dental operations was often maintained by blowing the vapour of ether or chloroform into the patients' oral or nasal pharynx. Junker's inhalers are a "blow over" device used with a hand-held bellows to bubble air through liquid chloroform and to the patient. It was initially intended for use with bichloride of methylene, a mixture of chloroform and methyl alcohol. Ferdinand Ethelbert Junker introduced his inhaler in 1867 as appointed physician to Samaritan Free Hospital for Women (although it didn't have that name until c.1904). Glass jar with liquid measure markers etched onto. The jar has a metal lid, with a metal tube descending into the jar. Two metal tubes are protuding out of the top of the lid, and each has a small section of rubber tubing attached. There is also a metal hook, used to attached the jar to the physicians (anaesthetist's) lapel.Stamped into frame of metal lid: LONDON MADEjunker, blow over, chloroform, samaritan free hospital for women

This inhaler appears to be a modification of the original Rendle's inhaler, developed in 1867 by Richard Rendle for use with bichloride of methylene. Rendle's original design was criticised as there was no clear way to regulate the dosage of anaesthetic and it was difficult to clean. Nevertheless, the inhaler was available until 1915. Richard Rendle was the second son of William Rendle (qv), Medical Officer of Health for St George the Martyr, Southwark, London, SE, of whom there is an account in the Dictionary of National Biography. Richard Rendle studied at Guy's Hospital, where he held the posts of House Surgeon, Surgical Registrar, and Demonstrator of Anatomy. He was afterwards House Surgeon at the Seamen's Hospital, Greenwich, and at the Waterloo Road Royal Infirmary for Women and Children, and then Resident Medical Officer at the Brompton Consumption Hospital. Resigning that post, he was put in medical charge of an emigrant ship to Australia, where he remained. He held several posts there: Resident Medical Officer of the Government Hospital, Fremantle; Medical Officer of the Lying-in Hospital and Hospital for Children; also Health Officer at Brisbane. In later years he practised at Taringa, near Brisbane, and died at Taringa, Queensland, on Aug 10th, 1907. The mask for the administration of bichloride of methylene was named after him in the instrument-makers' catalogues.

Malachite is a water soluble, crystalline, triphenyl methylene chloride salt. It has a close relationship to copper because it is common for Malachite and copper to come from the same ore. Malachite often has shades of green, making it also known as Malachite Green. As a result of it's colour, it is known for being a dye and has been used in the dye industry, the textile industry and in medical fields. Cobar in New South Wales is well known for it's mining. This is because of the number of important deposits present in the area and include three important mining belts where most of the materials are found. These are the 'Cobar belt', the 'Canbelego belt' and the 'Girilambone belt'. The 'Cobar belt' runs underneath the main town. Copper was first discovered in Cobar in 1869 and since then, many deposits of other materials have been found, including Malachite.This specimen is significant because it comes from Cobar, NSW and represents the many deposits of materials found there. Cobar has a long history of mining and is a source of Australia's copper minerals. Malachite is often found in copper deposits meaning that it is representative of Cobar's copper production. Malachite is known for it's vivid green colour and as a result, has many uses, such as meaning used as a dye. This makes it a valuable material and highly significant. 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 hand-sized mineral with shades of brown , white and light green throughout.geological specimen, geology, geology collection, burke museum, beechworth, malachite, copper, water soluble, cobar, cobar mines, cobar mining, cobar nsw, nsw, new south wales, mining belts, ore, copper ore, malachite green, dye, green, dye industry, textile industry, desposits, canbelego, girilambone, alfred selwyn
