A Fresnel lens is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use primarily in lighthouses.  Made from high-quality glass Fresnel lenses were used originally in lighthouses and later for many other applications They were later being used for automobile headlamps, brake, parking, and turn signal lenses, and many other applications. Fresnel lenses used in lighthouses were considered state of the art from the late 19th through to the middle of the 20th century. The subject item is a Fresnel replacement lens used in a ships navigation light. For lighthouses, these lenses have now been replaced with much less expensive and more durable aerobeacons, which themselves often contain plastic Fresnel lenses. The lens design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The catadioptric form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source making the light visible from greater distances.The subject item at this time cannot be associated with a historical event, person or place, provenance is unknown, the item is a replacement for a ships navigation light and it is believed to have been produced before 1950.Fresnel glass replacement lens for a navigation lamp of a ship.

This hand written letter, in black ink script on blue lined paper, is impressed with the official stamp of the Victoria Steam Navigation Board. The left margin has the reference “S82/12" It is transcribed: "Victoria Steam Navigation Board, Melbourne, January 12th 1882 To Frederick Chapman, Master, S.S. "Julia Percy" You are herewith furnished with a copy of the report of the Official Court which assembled to enquire into the circumstances attending the collision between the steamers "Julia Percy" and "Nelson" off Apollo Bay near Cape Otway on the morning of the 25th December 1881, and you are hereby expected to attend at the Board Room, Custom House, Melbourne, at 2pm, on 13th January instant to show cause why you should not be censured accordingly. [Signature] Secretary" This document refers to the matter of a collision between two steamships, the Julia Percy and the Nelson, on 25th December 1881. The Julia Percy was at that time owned by her first owners, the Warrnambool Steam Packet Company, and she sailed under the command of Captain Chapman. She had left Melbourne the evening of 24th December, with about 150 passengers, sailing in fine weather through Port Phillip Heads around 9pm. She was headed for Warrnambool, Belfast (now named Port Fairy) and Portland. The Julia Percy was off Apollo Bay when Captain Chapman was woken by the ship’s whistle after midnight, the steamer Nelson being on a collision course with the Julia Percy.[See Link.] The Nelson struck Julia Percy midship. Boats were lowered from the ship (apart from a damaged lifeboat) and about 30-40 of the passengers boarded the Nelson. The engine room and the forehold were checked and found clear of water. The company manager, Mr Evans, had been on the Nelson, so he boarded and inspected the Julia Percy and the decision was made to continue on to Warrnambool with the passengers as there appeared to be no immediate danger. However, Captain Thomas Smith said the Nelson was taking on water, so Julia Percy followed her for about an hour towards Melbourne on standby in case of need. Then Julia Percy turned around towards Warrnambool again. Shortly afterwards the Nelson turned to follow her, the ships stopped and passengers were returned to Julia Percy, and three from Julia Percy boarded the Nelson. Both ships proceeded on their way. Julia Percy passed Cape Otway light afterwards, signalling that there had been a collision. It was discovered later that one of the passengers was missing, then thought to have boarded the Nelson but later thought to have fallen into the sea and drowned while trying to jump from Julia Percy to Nelson. There had been 3 tickets purchased under the same name of that passenger “Cutler”; a father, son and friend named Wordsworth, which had caused quite some confusion. No further mishap occurred to either ship and both the Julia Percy and the Nelson reached their destinations safely. An enquiry was instigated by the Victoria Steam Navigation Board regarding the cause of the accident between the two steamships, in connection with the death of Cutler who was supposed to have lost his life by the collision. The enquiry resulted in the following decision: "The Victorian Steam Navigation Board having taken into consideration the points urged by Captain Thos [Thomas] Smith and also by his legal advisers, is of opinion that the charge prepared against him has been sustained, but taking into consideration Captain Smith’s previous good conduct and character, the board suspends his master’s certificate No 227 issued by this board for a period of six calendar months from this date – Robert Fullarton, Chairman. “The Victorian Steam Navigation Board having beard the statement of Captain Frederick Chapman urged in his defense to the charge of dereliction of duty as master of the Julia Percy, in having no standing order on board that vessel to be called in the event of any approaching steamer’s lights being seen, find such charge sustained, and censure him accordingly – Robert Fullarton, Chairman.” ABOUT “JULIA PERCY” The S.S. Julia Percy (later named Leeuwin ) was an iron passenger-cargo steam ship built in 1876. At one point in time the Julia Percy would sail from Warrnambool to Melbourne every Friday and return from Melbourne to Warrnambool every Tuesday. The cost of a return ticket for a Saloon Fare was £1.0.0. She would sail “if practical and weather permitting”. Shipping was the cheapest and most practical means of carrying produce and goods during the period 1840-1890. Regular domestic steamer services commenced in the Warrnambool district in the late 1850’s and by 1870 the passenger trade was booming. Produce was loaded from the jetty into ‘lighters’ (small boats), which took it to the ships at anchorage in the bay. Passengers were taken to the ship’s side then climbed aboard up ladders or gangways. The coming of the railway in October 1889 meant the gradual decline and end of the steam shipping era. The Julia Percy was built in Glasgow by Thomas Wingate & Company, Whiteinch, in 1876 for the Warrnambool Steam Packet Company, which commissioned her for trade in Victoria’s western district. She was first registered in Warrnambool, Victoria in 1876. The Julia Percy changed hands several times. Her next owner was the Western Steam Navigation Co (1887), managed by Mr. T.H. Osborne (the company’s office was on the corner of Timor and Liebig Streets, Its north-western wall is now part of the current Warrnambool Regional Art Gallery. ) The Melbourne Steamship Co became the next owners (1890), followed by William Howard Smith and Sons (1901) for use in Queensland coastal trades, then she was bought by George Turnbull in 1903 and used for local mail contract in Western Australia. The Julia Percy was sold to the Melbourne Steamship Company Ltd. (1906) and re-named the “Leeuwin” but continued in her Western Australian coastal run. She was converted into a coal hulk in Melbourne in 1910 as a result of damaged caused when she was driven against the jetty at Dongara during a gale. The ship was eventually dismantled and scuttled in Bass Strait on 28 December 1934. The document is significant for its association with the wreck of the Leeuwin (Julia Percy), which is on the Victorian Heritage Register, VHR S413. . It is historically significant for being a rare artefact that has potential to interpret aspects of Western Victoria’s 19th century steamship trade and Victorian cultural history. The Leeuwin (Julia Percy) is listed on the Victorian Heritage Register as being historically significant ‘as one of only four wrecks of steamships in Victorian waters associated with the western district of Victoria’s coastal steamship trade.

This is a passenger ticket for the Screw Steamship "Otway".It was built in 1872 at Glasgow for the Warrnambool Steam Packet Company. She traded to and from the Western Ports until 1878.when she was sold for the Melbourne West Australian trade. She was broken up at Sydney in 1924. The Warrnambool Steam Packet Company commenced in 1868 and operated on the Western Ports run using the ships "Edina", "Rob Roy", "Otway", " Nelson" and "Julia Percy".In 1878 it became the Western Steam Navigation Company which operated until 1896. There is no information available on the passenger James Gilligan This item which may come from the old Warrnambool Museum is of considerable interest as a rare memento of steam travel to and from the Western Ports in the 19th century. Warrnambool was an important port at that time and this item is part of our marine history.

Menus used on P&O liners SS Himalaya and SS Arcadia 1955-56. After the Great war of 1914-18, Australia experienced what up until then had been its biggest surge in immigration from Europe. Australia was seen as the great land of opportunity and became one of the top places to migrate to, particularly from Britain. The increase in migration to Australia led Britain’s leading shipping line to the Far East, the Peninsular and Oriental Steam Navigation Company (P&O;), to invest in a fleet of new ships of around 20,000 tonnes each to handle the business coming their way.29 Cruise Ship Menus from P&O cruises 1955-56Peninsula & Oriental Steam Navigation Companycruise liners, migrants, menus, p&o

With the advent of audio content available through i-phones and other small devices, the demand for a dedicated audio, easily portable player for the blind and vision impaired became louder and louder. Two organisations competed to deliver this and Canadian company Humanware developed the Victor Classic as a table top player that relied on discs. As CDs had been introduced into the library some years before, this allowed borrowers to have the advantages of 4 track cassettes within a digital medium. The Victor Reader Classic used simple features that made it easy for clients to navigate through a book or magazine. The player played both DAISY and music CDs. The function keys included controls for variable tone, volume, speed and creation of bookmarks, sleep time and you could navigate by chapter and page on DAISY books.
