  • Thermograph – Ex Australian Antarctic Division

    Thermograph – Ex Australian Antarctic Division

    A vintage instrument and an essential piece of Antarctic equipment something to measure and record the temperature over time.

    This is the weekly “Bureau of Meteorology” CBM metal cased design with clockwork drum – which ticks away quite pleasantly.

    We say ex Australian Antarctic because there is a big sticker on the back saying it was disposed – we will leave it for others to remove.

    Weighs a bit so a postage supplement may be required – enquire and we will do our best ….

    The principle used is that a coiled bi-metallic strip [steel and copper] is attached to a long light lever or arm that holds a tiny pen. Small movements in the bi-metallic strip cause much larger movements at the end of the arm making the pen rise and fall with changes in temperature – these changes being recorded on the chart which is clockwork driven and turns once every week – in this case. A simple but effective analogue process.

    Thermograph from the Australian Antarctic Division which has no doubt been safely digitised and using poisonous batteries rather than eco friendly hand cranked clocks.

  • A Vindication of Phrenology – W. Matthieu Williams – First edition 1894

    Published by Chatto and Windus, London in 1894 a first edition of this “vindication” book by the esteemed phrenologist Williams.

    Largish octavo, xxii, 428 pages. Frontispiece photograph of the author pondering the shape of the head and its bumps crevices. Several illustrated plates and figures within the text. A very good copy.

    The author was a distinguished scientist and Fellow of the Royal Astronomical Society and Royal Chemical Society. He also authored a book titled “The Chemistry of Cooking” … Heston please note.

    If you don’t understand phrenology well this is the book for you … interest in the pseudo science was waning by this date maybe hence the vindication … some good things came out of it though … it’s all a matter of perspective.

    Phrenology explained and vindicated!

  • Encyclopedia of the Antarctic – Edited Beau Riffenburgh- 2 Volumes

    Published by Routledge in 2006 this two-volume set is regarded as the font of all things Antarctica.

    A substantial effort the number of distinguished contributors runs to over a hundred.

    Two quarto volumes, 1,272 pages heavily illustrated with all sorts, high technical level with many maps, charts, explanatory diagrams etc. Very good condition. Weighs in at circa 3.6kgs so not really suitable for Overseas postage.

    The elements relating to the History of Exploration and History of Science are understandably our favourites. Other broader topics include … Atmosphere; Birds; Conservation; Geography; Glaciology; Technology; Oceanography; Physics and astronomy etc.

    It is all here in the Encyclopedia of the Antarctic – more than a winter’s reading

  • Scientific Instrument – Measuring magnetic field produced by an electrical current against the Earth’s magnetic field (compass) – Flemings Right Hand Rule etc – likely Philip Harris c 1930.

    Scientific Instrument – Measuring magnetic field produced by an electrical current against the Earth’s magnetic field (compass) – Flemings Right Hand Rule etc – likely Philip Harris c 1930.

    Nicely made pine / mahogany box with removeable glass lid; back wall hinges down. Inside we have a good sensitive compass and two sets of parallel wires which are internally connected to the two brass terminals on the front wall. We say likely Philip Harris of Birmingham England, it is not marked, but it sure looks like their reliable work to us. 11cm by 11cm 4 cm deep – very good condition

    The application of various levels of current will provide a changing level of deflection in the compass. This will vary also as the instrument is revolved around the compass line. i.e. the true reading is gained with the parallel wires lined up North / south with the compass. There will be zero deflection at 90 degrees to that. Of course the instrument can be used to measure current in reverse principle – see out notes on the tangent galvanometer.

    The maths involved is pretty straight forward and very enlightening for anyone who has missed the physics challenge at school or for an interested youngster about to embark on it.

    Flemings Right Hand Rule proves very reliable

    The 2008, soft cover version, published by Allen & Unwin, Sydney. Small quarto, 414 pages and 60 pages of plates. Very good condition. A substantial and heavy book not really suitable for overseas postage.
