The investigation of the x-ray appears early on to have been a priority research topic at the University of Melbourne’s School of Physics. This interest was sparked by the appointment in 1889 of Professor T.R. Lyle. Lyle, who was head of the school until 1915, is thought to have been the first person in Australia to have taken an x-ray photograph. A copy of this photograph can be found in the School of Physics Archive. For this particular experiment Lyle actually made his own x-ray tube. His successor, Professor Laby, continued to work with x-rays. During the 1920s Laby worked on the x-ray spectra of atoms and in 1930 he co-published with Dr. C.E. Eddy, Quantitative Analysis by X-Ray Spectroscopy. Also with Eddy, Laby produced the landmark paper Sensitivity of Atomic Analysis by X-rays. Laby went on to have an x-ray spectrograph of his own design manufactured by Adam Hilger Ltd. (see cat. No. 38). School of Physics, the University of Melbourne Cat. No. 22.

A minor modification is the rotating anode type that extends the life and increases the available power of the tube by presenting a new portion of the anode when required. “P125/20/40/NrF038803 (?)

Stephen Spark compiled horses performance records starting in 1983 on his typewriter. Avian Again: Riverina Herald, Tuesday August 19, 1952 Mr Harry Holmfield's pacer Avian Again made a spectacular return to racing on Saturday night at Harold Park when he took one of the main races in ; his first appearance this season. Bookmakers were ready for his visit to Sydney for they did not bet better than 6/4 On. The Ech uca owned horse, driven by Gor don Rothacker, was never in danger and led almost through out to score comfortably by over one length. Sky Pilot, the N.Z. pacer, who has won his last three races at Harold Park, challenged at one stage but was easily beaten off. Mr Holmfield is very impress ed with trotting in Sydney where the attendances eclipse those at the galloping meetings in the day. Avian Again's race on Saturday night was worth ,£600—£450 to the winning own er. 'Next month there will be a race with six heats worth £700 each and £2500 for the final. It is likely that Avian Again in this race will strike his half-brother, the famous Avian Derby, who Has not been retired to the stud as expected. Next week Avian Again will race in the fastest class at Har old Park from the scratch mark. He has yet to appear at the. Melbourne Showgrounds and has been shrewdly placed. . Later in the season he will be taken to Perth where the Inter Dominion championships will, be held in February.Avian Again raced from 1951 (4yo) through to 1957 (10yo). Had a Winning Streak of 8 wins.

Jacqueline Eager Student Projects Placement, Cultural Collections 2005 In 1913 Coolidge overcame the limitation of the narrow operating range of the gas X-ray tubes with the invention of the vacuum X-ray tube. A filament heated by an electric current directly releases electrons by thermionic emission. In thermionic emission, electrons are emitted from a metal surface directly by the application of an electric current to heat a wire filament. The electrons accelerate to the anode and produce X-rays. The anode has associated cooling fins due to the high temperatures attained by the release of kinetic energy by the electrons on colliding with the anode. Internal Glass sleeve: “A941/L2593/2821”

In the Homeland Mr Frazier found it the increasing practice to take the great opera masterpieces and give them on the concert platform in more of less liberal excerpts. With characteristic generosity. He purchased the copies and presented them to the Choral Society. Bendigo has thus an opportunity to hear the latest idea. We are sure the musical public will appreciate this, though of course. . . . . It is interesting to note that when this great work was first performed in Paris, on March 19th, 1859, it was somewhat coldly received, to the composer's great grief, as he, with the instinct of genius, . . . . The Compact: Introduction: Faust, aged and worn, weary with long pondering over learned treatises, in a pessimistic mood wonders whether the work is worth while. Memories of an early love stir strangely in his being, and he, in his doubting mood, questions all things, In despair he would welcome death, and finding no answer from the heavens, he appeals to the powers of ill. To his great surprise, he is at once answered by Mephistopheles and a colloquy then ensues in which the Evil One promises him Gold? Glory? A Kingdom? No! No! It mist be 'Youth!' That can be done also. Faust is dubious, but on Mephistopheles bringing a vision of beauteous Margarita at is dubious, but on Mephistopheles be 'Youth!' That can be done also. Faust is dubious, but on Mephistopheles bringing a vision of beauteous Margarita at her wheel he agrees, and signs the compact. 'Up Here I am at thy command, Down There thou servest me!' At The Fair: Mephistopheles then asks Faust to the Fair where they mix with the revelry of the students, soldiers and merry maidens. He gets a glimpse of Margarita. The Evil One is again busy putting Suspicious and quarrelsome thoughts into good comrades minds. . . . The Wooing: Poor Siebel, the ardent, faithful lover of Margarita, finds himself somewhat overshadowed by the young and handsome Faust. Mephistopheles in a mocking mood tells him that every flower that he plucks will perish in his hands. He finds this prediction verified when he plucks the flowers for his lady love, but when in faith he scouts the Evil One, he conquers, and the spell is broken. Faust, filled with an ardent and pure passion, approaches the dwelling of Margarita, with an offering of priceless jewels, provided by the . . . . . The Return Of Valentine: Valentine, the soldier brother of Margarita, leaves for the wars, giving the care of his sister to her faithful lover, Siebel. On his return, covered with glory, and ardent to meet his people again, he hears the story of the flouting of Margarita by Faust. In this part the soldiers are welcomed home by their comrades in the male part of the song 'Fold the flag my brothers,' followed by the celebrated chorus (usually known as the 'Soldier's Chorus' Glory and love to the men of old.' It has been set, in this edition, for full choir. Mephistopheles, the evil genius, in a spirit of raillery, and exultant that his plans are working to . . . . The Price: Faust, repentant, desires to do justice to Margarita and again be her lover. Margarita is almost demented at the loss of her brother. Mephistopheles not to be cheated, thwarts the good impulse of Faust and demands his price. He also endeavors to make Margarita despair, but owing to the simple faith of the . . . . The End. A Question You give you name, your time, your pelf To ease your woe: But what do you give of your own self To pay the debt you owe? You open a Home for helpless ones, And you shut them in with care; Of what think you is their share? You talk and you write; you organise; All this, we know, is true; But how do you spread the spark divine, The deep-down soul of you? -A Simkins. Benevolent Asylum Appeal. The Committee of Management directing the works of the Asylum desire to bring before an always generous public the claims of the Instruction for financial support. The Appeal for 5000 pounds has been launched in the full belief that the case is a good one, and in the confident hope that it will be successful. The work carried on by the Asylum covers a big field, extending as it does from Swan Hill in the north and Melbourne in the south. Inmates from all parts of the State are given a comfortable home, and properly cared for in the eventide of their lives. There are at present in the Asylum 164 old men and women. In addition to this work the Committee thoroughly investigate and dispense relief in food to from 150 to 200 adults and from 300 to 400 children each week, and also issues a large number of blankets, boots and clothing garments to necessitious applicants. The recipients of this relief are principally widow and their little ones, and the wives and children who are dependents of miners suffering from the dread Miners' Complaint. The Committee in orgainising this branch of its charity work, has, to a great extent, prevented a large amount of waste, through overlapping and duplication of effort. It now appeals to the public for the above amount in order that be may still be able to continue charity work among the poor and necessitous of Bendigo and District.
