3 Sets held numbered 106, 989 and 990.A series of duotone printS of Sydney Harbour Bridge housed in a hand-made portfolio, bound in the traditional method. Produced probably in 1998. Intended for presentations from NMIT. From National Library of Australia record 'Limited to 1000 prints, increasing in value as the edition is sold out, "The prints are colour calibrated for display under tungsten lighting. They are individually numbered, embossed and placed between acid free trace paper to help protect the prints surface".tony yeates, sydney harbour bridge, presentation pieces, nmit

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. Jacqueline Eager Student Projects Placement, Cultural Collections 2005 The original X-ray tubes relied on low pressure operation. The electrons and positive ions are produced in the residual gas. Positive ions are accelerated towards the cathode and release electrons which on hitting the anode produce X-rays. These early gas X-ray tubes operated satisfactory only over a narrow pressure range.
