In 1821 the French otologist Jean Marc Itard irrigated the ear canal to remove hard wax, by using a syringe prototype designed for enemas which was made from tin and brass. This glass and cork ear syringe was manufactured by the Ambson Company in the United Kingdom, about eighty years afterwards. Its lightweight properties would have been ideal for application to the sensitive regions of the ear canal. https://www.racgp.org.au/the-racgp/history/the-racgp-museum-collection/syringes/ambson-ear-syringe Otology is a branch of medicine which studies normal and pathological anatomy and physiology of the ear (hearing and vestibular sensory systems and related structures and functions) as well as their diseases, diagnosis and treatment. Otologic surgery generally refers to surgery of the middle ear and mastoid related to chronic otitis media, such as tympanoplasty, or ear drum surgery, ossiculoplasty, or surgery of the hearing bones, and mastoidectomy. Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. https://en.wikipedia.org/wiki/Otology The ear syringe 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” 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. ABOUT THE “W.R.ANGUS COLLECTION” Doctor William Roy Angus M.B., B.S., Adel., 1923, F.R.C.S. Edin.,1928 (also known as Dr Roy Angus) was born in Murrumbeena, Victoria in 1901 and lived until 1970. He qualified as a doctor in 1923 at University of Adelaide, was Resident Medical Officer at the Royal Adelaide Hospital in 1924 and for a period was house surgeon to Sir (then Mr.) Henry Simpson Newland. Dr Angus was briefly an Assistant to Dr Riddell of Kapunda, then commenced private practice at Curramulka, Yorke Peninsula, SA, where he was physician, surgeon and chemist. In 1926, he was appointed as new Medical Assistant to Dr Thomas Francis Ryan (T.F. Ryan, or Tom), in Nhill, Victoria, where his experiences included radiology and pharmacy. In 1927 he was Acting House Surgeon in Dr Tom Ryan’s absence. Dr Angus had become engaged to Gladys Forsyth and they decided he further his studies overseas in the UK in 1927. He studied at London University College Hospital and at Edinburgh Royal Infirmary and in 1928, was awarded FRCS (Fellow from the Royal College of Surgeons), Edinburgh. He worked his passage back to Australia as a Ship’s Surgeon on the on the Australian Commonwealth Line’s T.S.S. Largs Bay. Dr Angus married Gladys in 1929, in Ballarat. (They went on to have one son (Graham 1932, born in SA) and two daughters (Helen (died 12/07/1996) and Berenice (Berry), both born at Mira, Nhill ) According to Berry, her mother Gladys made a lot of their clothes. She was very talented and did some lovely embroidery including lingerie for her trousseau and beautifully handmade baby clothes. Dr Angus was a ‘flying doctor’ for the A.I.M. (Australian Inland Ministry) Aerial Medical Service in 1928 . Its first station was in the remote town of Oodnadatta, where Dr Angus was stationed. He was locum tenens there on North-South Railway at 21 Mile Camp. He took up this ‘flying doctor’ position in response to a call from Dr John Flynn; the organisation was later known as the Flying Doctor Service, then the Royal Flying Doctor Service. A lot of his work during this time involved dental surgery also. Between 1928-1932 he was surgeon at the Curramulka Hospital, Yorke Peninsula, South Australia. In 1933 Dr Angus returned to Nhill and purchased a share of the Nelson Street practice and Mira hospital (a 2 bed ward at the Nelson Street Practice) from Dr Les Middleton one of the Middleton Brothers, the current owners of what previously once Dr Tom Ryan’s practice. Dr Tom and his brother had worked as surgeons included eye surgery. Dr Tom Ryan performed many of his operations in the Mira private hospital on his premises. He had been House Surgeon at the Nhill Hospital 1902-1926. Dr Tom Ryan had one of the only two pieces of radiology equipment in Victoria during his practicing years – The Royal Melbourne Hospital had the other one. Over the years Dr Tom Ryan had gradually set up what was effectively a training school for country general-practitioner-surgeons. Each patient was carefully examined, including using the X-ray machine, and any surgery was discussed and planned with Dr Ryan’s assistants several days in advance. Dr Angus gained experience in using the X-ray machine there during his time as assistant to Dr Ryan. When Dr Angus bought into the Nelson Street premises in Nhill he was also appointed as the Nhill Hospital’s Honorary House Surgeon 1933-1938. His practitioner’s plate from his Nhill surgery is now mounted on the doorway to the Port Medical Office at Flagstaff Hill Maritime Village, Warrnambool. When Dr Angus took up practice in the Dr Edward and Dr Tom Ryan’s old premises he obtained their extensive collection of historical medical equipment and materials spanning 1884-1926. A large part of this collection is now on display at the Port Medical Office at Flagstaff Hill Maritime Village in Warrnambool. In 1939 Dr Angus and his family moved to Warrnambool where he purchased “Birchwood,” the 1852 home and medical practice of Dr John Hunter Henderson, at 214 Koroit Street. (This property was sold in1965 to the State Government and is now the site of the Warrnambool Police Station. and an ALDI sore is on the land that was once their tennis court). The Angus family was able to afford gardeners, cooks and maids; their home was a popular place for visiting dignitaries to stay whilst visiting Warrnambool. Dr Angus had his own silk worm farm at home in a Mulberry tree. His young daughter used his centrifuge for spinning the silk. Dr Angus was appointed on a part-time basis as Port Medical Officer (Health Officer) in Warrnambool and held this position until the 1940’s when the government no longer required the service of a Port Medical Officer in Warrnambool; he was thus Warrnambool’s last serving Port Medical Officer. (Masters of immigrant ships arriving in port reported incidents of diseases, illness and death and the Port Medical Officer made a decision on whether the ship required Quarantine and for how long, in this way preventing contagious illness from spreading from new immigrants to the residents already in the colony.) Dr Angus was a member of the Australian Medical Association, for 35 years and surgeon at the Warrnambool Base Hospital 1939-1942, He served with the Australian Department of Defence as a Surgeon Captain during WWII 1942-45, in Ballarat, Victoria, and in Bonegilla, N.S.W., completing his service just before the end of the war due to suffering from a heart attack. During his convalescence he carved an intricate and ‘most artistic’ chess set from the material that dentures were made from. He then studied ophthalmology at the Royal Melbourne Eye and Ear Hospital and created cosmetically superior artificial eyes by pioneering using the intrascleral cartilage. Angus received accolades from the Ophthalmological Society of Australasia for this work. He returned to Warrnambool to commence practice as an ophthalmologist, pioneering in artificial eye improvements. He was Honorary Consultant Ophthalmologist to Warrnambool Base Hospital for 31 years. He made monthly visits to Portland as a visiting surgeon, to perform eye surgery. He represented the Victorian South-West subdivision of the Australian Medical Association as its secretary between 1949 and 1956 and as chairman from 1956 to 1958. In 1968 Dr Angus was elected member of Spain’s Barraquer Institute of Barcelona after his research work in Intrasclearal cartilage grafting, becoming one of the few Australian ophthalmologists to receive this honour, and in the following year presented his final paper on Living Intrasclearal Cartilage Implants at the Inaugural Meeting of the Australian College of Ophthalmologists in Melbourne In his personal life Dr Angus was a Presbyterian and treated Sunday as a Sabbath, a day of rest. He would visit 3 or 4 country patients on a Sunday, taking his children along ‘for the ride’ and to visit with him. Sunday evenings he would play the pianola and sing Scottish songs to his family. One of Dr Angus’ patients was Margaret MacKenzie, author of a book on local shipwrecks that she’d seen as an eye witness from the late 1880’s in Peterborough, Victoria. In the early 1950’s Dr Angus, painted a picture of a shipwreck for the cover jacket of Margaret’s book, Shipwrecks and More Shipwrecks. She was blind in later life and her daughter wrote the actual book for her. Dr Angus and his wife Gladys were very involved in Warrnambool’s society with a strong interest in civic affairs. He had an interest in people and the community They were both involved in the creation of Flagstaff Hill, including the layout of the gardens. After his death (28th March 1970) his family requested his practitioner’s plate, medical instruments and some personal belongings be displayed in the Port Medical Office surgery at Flagstaff Hill Maritime Village, and be called the “W. R. Angus Collection”.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 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.Glass ear syringe. Has cork stopper at top and cotton wrapped at base of plunger.

The first all transistor hearing aids appeared in 1953. They were created to replace vacuum tubes; they were small, required less battery power and had less distortion and heat than their predecessor. The vacuum tubes were typically hot and fragile, so the transistor was the ideal replacement. The size of these transistors led to developments in miniature, carbon microphones. These microphones could be mounted on various items. There were body hearing aids where the earpiece was connected to the hearing aid and battery pack worn on the body. Ear level hearing aids consisted of eyeglass, behind the ear (BTE), in the ear (ITE), and in the canal (ITC, CIC) hearing aids. A Widex 25 hearing aid from the 1950's made in Denmark.

The first electrical hearing aids were carbon and were made possible by the invention of the carbon microphone and were made between 1900 and 1939. Carbon, which can be made to amplify electrical current, was used to provide some amplification prior to the invention of vacuum tubes. Later models often came with mechanical (carbon) amplifiers to try to boost the amount of amplification. The carbon microphone was originally invented for use in the telephone and had the properties of being able to modulate current. It is this property that made it useful in the early electrical hearing aids. An example of a carbon hearing aid. This has an imitation tortoise shell casing.

Although Lee DeForest invented the triode vacuum  in 1906, it was not employed in hearing aids until 1921. The first hearing aid using a vacuum tube was purported to have been made by Earl C. Hanson. He called his hearing aid the Vactuphone. It used one small peanut tube (below right) to amplify the output of a carbon hearing aid. The Globe Hearing Aid Company and Western Electric collaborated to manufacture the Vactuphone. By the early 1940s, Raytheon had developed miniature vacuum tubes. It was these miniature vacuum tubes that made body-worn hearing aids a reality. Unfortunately, the power requirements of these aids made it necessary to use two relatively large batteries—an "A" battery to power the filaments of the vacuum tubes and a "B" battery to supply the high-voltage for the plate current. The batteries were worn external to the hearing aid itself and the name "Two-piece" hearing aid was used to describe them. Until about 1945 "Two-piece" hearing aids were the norm. However, improved vacuum tube design reduced current requirements. As a result, battery manufacturers were able to reduce the size of the batteries used in hearing aids. At the same time, electronic components were also being miniaturized. This allowed the hearing aid manufacturers to design hearing aids with internal batteries. After 1945, these "One-piece" hearing aids quickly replaced the more cumbersome "Two-piece" hearing aids. With continuing improvements in both batteries and components, hearing aids continued to reduce in size until 1953 when the vacuum tube was suddenly supplanted by the transistor.Fawn plastic hearing aid with metal clip on back and wires leading from the bottom.

In addition to the Nicolet Corporation, Bell Laboratories expanded upon the hearing aid business by developing a hybrid digital-analog hearing aid. When the hearing aid was put on in the market, it was instantaneously successful. This development helped bring major changes to the world of the hearing aid. The next major milestone was creating an all-digital hearing aid. The Oticon Company developed the first digital hearing aid in 1995, but it was only distributed to audiological research centers for research on digital technology in the realm of acoustic amplification. The Senso was the first commercially successful, all-digital hearing aid, and was created by Widex in 1996. After the success of the Senso, Oticon began marketing their own hearing aid, the DigiFocus. Presently, the digital hearing aid is now become programmable. By making the hearing aid programmable, it has allowed hearing aids to be capable of regulating sound on their own, without using a separate control. The hearing aid can now adjust itself depending on what environment it is in and often does not even need a physical volume control button. Silver metal case with side clips and hearing aid attached. Has battery compartment for AA batteries. Volume control is the top left hand corner. Comes with its black case "C OF A/CALAID/101862" on back of case. "ANGUS & COOTE/Acoustics/HEARING AIDS" on inside cover of case
