magnifying glass, c. 19th century
A pocket magnifying glass was a versatile scientific tool. It was ideal for situations in which the specimen was too small to be observed under a magnifying glass and access to a larger microscope would have been impossible.It could be taken on field expeditions and used to examine botanical, zoological and mineralogical specimens. This small magnifying glass could be used for examining specimens of plants or rocks or jewellery.Simple,pocket microscopes had a significant impact on the the general public’s appreciation of both science and the natural world by making the microscopic world accessible and exciting.A small brass pocket magnifying glass with resting arm. The cardboard box is blue / black in colour.magnifying-glass scientific-instrument -

Photograph, C. 1891
Photograph shows the ship FIJI where she met her demise, in Wreck Bay, on the shipwreck coast of South West Victoria. The three-masted iron barque Fiji had been built in Belfast, Ireland, in 1875 by Harland and Wolfe for a Liverpool based shipping company. The ship departed Hamburg on 22nd May 1891 bound for Melbourne, under the command of Captain William Vickers with a crew of 25. The ship’s manifest shows that she was loaded with a cargo of 260 cases of dynamite, pig iron, steel goods, spirits (whisky, schnapps, gin, brandy), sailcloth, tobacco, coiled fencing wire, concrete, 400 German pianos (Sweet Hapsburg), concertinas and other musical instruments, artists supplies including brushes, porcelain, furniture, china, and general cargo including candles. There were also toys in anticipation for Christmas, including wooden rocking horses, miniature ships, dolls with china limbs and rubber balls. On September 5th, one hundred days out from Hamburg in squally and boisterous south west winds the Cape Otway light was sighted on a bearing differing from Captain Vickers’ calculation of his position. At about 2:30am, Sunday 6th September 1891 land was reported 4-5 miles off the port bow. The captain tried to put the ship on the other tack, but she would not respond. He then tried to turn her the other way but just as the manoeuvre was being completed the Fiji struck rock only 300 yards (274 metres) from shore. The place is known as Wreck Bay, Moonlight Head. Blue lights were burned and rockets fired whilst an effort was made to lower boats but all capsized or swamped and smashed to pieces. Two of the younger crewmen volunteered to swim for the shore, taking a line. One, a Russian named Daniel Carkland, drowned after he was swept away when the line broke. The other, 17 year old able seaman Julius Gebauhr, a German, reached shore safely on his second attempt but without the line, which he had cut lose with his sheath-knife when it become tangled in kelp. He rested on the beach a while then climbed the steep cliffs in search of help. At about 10am on the Sunday morning a party of land selectors - including F. J. Stansmore, Leslie Dickson (or Dixon) and Mott - found Gebauhr. They were near Ryans Den, on their travels on horseback from Princetown towards Moonlight Head, and about 5km from the wreck. Gebauhr was lying in the scrub in a poor state, bleeding and dressed only in singlet, socks and a belt with his sheath-knife, ready for all emergencies. At first they were concerned about his wild and shaggy looking state and what seemed to be gibberish speech, taking him to be an escaped lunatic. They were reassured after he threw his knife away and realised that he was speaking half-English, half-German. They gave him food and brandy and some clothing and were then able to gain information about the wreck. Some of the men took him to Rivernook, a nearby guest house owned by John Evans, where he was cared for. Stansmore and Dickson rode off to try and summon help. Others went down to the site of the wreck. Messages for rescuing the rest of the crew were sent both to Port Campbell for the rocket rescue crew and to Warrnambool for the lifeboat. The S.S. Casino sailed from Portland towards the scene. After travelling the 25 miles to the scene, half of the Port Campbell rocket crew and equipment arrived and set up the rocket tripod on the beach below the cliffs. By this time the crew of the Fiji had been clinging to the jib-boom for almost 15 hours, calling frantically for help. Mr Tregear from the Rocket Crew fired the line. The light line broke and the rocket was carried away. A second line was successfully fired across the ship and made fast. The anxious sailors then attempted to come ashore along the line but, with as many as five at a time, the line sagged considerably and some were washed off. Others, nearly exhausted, had to then make their way through masses of seaweed and were often smothered by waves. Only 14 of the 24 who had remained on the ship made it to shore. Many onlookers on the beach took it in turns to go into the surf and drag half-drowned seamen to safety. These rescuers included Bill (William James) Robe, Edwin Vinge, Hugh Cameron, Fenelon Mott, Arthur Wilkinson and Peter Carmody. (Peter Carmody was also involved in the rescue of men from the Newfield.) Arthur Wilkinson, a 29 year old land selector, swam out to the aid of one of the ship’s crewmen, a carpenter named John Plunken. Plunken was attempting to swim from the Fiji to the shore. Two or three times both men almost reached the shore but were washed back to the wreck. A line was thrown to them and they were both hauled aboard. It was thought that Wilkinson struck his head on the anchor before s they were brought up. He remained unconscious. The carpenter survived this ordeal but Wilkinson later died and his body was washed up the next day. It was 26 year old Bill Robe who hauled out the last man, the captain, who had become tangled in the kelp. The wreck of the Fiji was smashed apart within 20 minutes of the captain being brought ashore, and it settled in about 6m of water. Of the 26 men on the Fiji, 11 in total lost their lives. The remains of 7 bodies were washed onto the beach and their coffins were made from timbers from the wrecked Fiji. They were buried on the cliff top above the wreck. The survivors were warmed by fires on the beach then taken to Rivernook and cared for over the next few days. Funds were raised by local communities soon after the wreck in aid of the sufferers of the Fiji disaster. Captain Vickers was severely reprimanded for his mishandling of the ship. His Masters Certificate was suspended for 12 months. At the time there was also a great deal of public criticism at the slow and disorganised rescue attempt to save those on board. The important canvas ‘breech buoy’ or ‘bucket chair’ and the heavy line from the Rocket Rescue was in the half of the rocket outfit that didn’t make it in time for the rescue: they had been delayed at the Gellibrand River ferry. Communications to Warrnambool were down so the call for help didn’t get through on time and the two or three boats that had been notified of the wreck failed to reach it in time. Much looting occurred of the cargo that washed up on the shore, with nearly every visitor leaving the beach with bulky pockets. One looter was caught with a small load of red and white rubber balls, which were duly confiscated and he was ‘detained’ for 14 days. Essence of peppermint mysteriously turned up in many settlers homes. Sailcloth was salvaged and used for horse rugs and tent flies. Soon after the wreck “Fiji tobacco” was being advertised around Victoria. A Customs officer, trying to prevent some of the looting, was assaulted by looters and thrown over a steep cliff. He managed to cling to a bush lower down until rescued. In 1894 some coiled fencing wire was salvaged from the wreck. Hundreds of coils are still strewn over the site of the wreck, encrusted and solidified. The hull is broken but the vessel’s iron ribs can be seen along with some of the cargo of concrete and pig iron. Captain Vickers presented Bill Robe with his silver-cased pocket watch, the only possession that he still had, as a token for having saved his life and the lives of some of the crew. (The pocket watch came with 2 winding keys, one to wind it and one to change the hands.) Years later Bill passed the watch to his brother-in-law Gib (Gilbert) Hulands as payment of a debt and it has been passed down the family to Gilbert Hulands’ grandson, John Hulands. Seaman Julius Gebauhr later gave his knife, in its hand crafted leather sheath, to F. J. Stansmore for caring for him when he came ashore. The knife handle had a personal inscription on it. A marble headstone on the 200m high cliffs overlooking Wreck Beach, west of Moonlight Head, paying tribute to the men who lost their lives when Fiji ran aground. The scene of the wreck is marked by the anchor from the Fiji, erected by Warrnambool skin divers in 1967. Amongst the artefacts salvaged from the Fiji are china miniature animals, limbs from small china dolls, rubber balls, a slate pencil, a glass bottle, sample of rope from the distress rocket and a candlestick holder. These items are now part of the Fiji collection at Flagstaff Hill Maritime Museum, along with Captain Vickers’ pocket watch and Julius Gebauhr’s sheath knife. Flagstaff Hill’s Fiji collection is of historical significance at a State level because of its association with the wreck Fiji, which is on the Victorian Heritage Register VHR S259. The Fiji is archaeologically significant as the wreck of a typical 19th century international sailing ship with cargo. It is educationally and recreationally significant as one of Victoria's most spectacular historic shipwreck dive sites with structural features and remains of the cargo evident. It also represents aspects of Victoria’s shipping history and its potential to interpret sub-theme 1.5 of Victoria’s Framework of Historical Themes (living with natural processes). The Fiji collection meets the following criteria for assessment: Criterion A: Importance to the course, or pattern, of Victoria’s cultural history. Criterion B: Possession of uncommon, rare or endangered aspects of Victoria’s cultural history Criterion C: Potential to yield information that will contribute to an understanding of Victoria’s cultural history.

Instrument - Sextant, Late 20th Century
In 1941, the scientific instrument manufacturing firms of Henry Hughes & Son Ltd, London, England, and Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.
