    A group of six brightly coloured trade cards by Liebig advertising their tasty products. Produced circa Mid 20thC and in very good condition. Comprehensive text in French on reverse.

    Delightful chromolithographs depicting various phases in Gerard Mercator’s life.

    Gerardus Mercator (1512-1594) a German-Flemish geographer studied at the University of Leuven. He appears in the matriculation records of 1530 … they still exist! In 1569 he created the principles that we now call the Mercator projection, fundamental to voyagers from that day forward. He produced a magnificent Atlas based on his projection technique and made many fine globes sold to Royalty and gentry all over Europe. Unfortunately, as were the time even though a devout Catholic he was accused of heresy and spent six months in prison. Each of these elements of his life is nicely displayed in this scarce card set.

    Mercator … his projection is everlasting

    Octavo, 112 pages of slide rule lovers delight. Covers the … Principle of the Slide Rule; Principle of Logarithms; Using the Slide Rule; Examples; Circular Slide Rules etc. Very good condition albeit a little creasing to the otherwise good dust jacket.

    The Preface starts … “The slide rule is considered by many a mysterious instrument requiring years of study before it can be used with facility”.

    Within twenty years sophisticated electronic calculators and personal computers made the slide made the slide rule obsolete and an “antique” of the past. Pity … to use the slide rule properly a knowledge of mathematics was required …

    A very interesting “modern” curiosity … get your slide rule today.

  • Manuscript Letter – Italian Astronomer Giuseppe Armellini – Portorecanati – 19th August 1922

    Manuscript Letter – Italian Astronomer Giuseppe Armellini – Portorecanati – 19th August 1922

    Returning proofs and with suggestions of a mathematical nature based on “derivate ordinaries” … ordinary derivatives. Our calculus a little rusty as also our Italian … appears to be connected to Maxwell’s Laws.

    Giuseppe Armellini (1887-1958) was born and died in Rome. He was Professor of Physics and Astronomy at several Italian Universities and Director of the Rome Astronomical Observatory for over 30 years. It was in the year of this letter [1922] that he took up his position at the Observatory of the Campidoglio which in 1936 he transferred to Monte Mario. A fire destroyed the Observatory in 1957 … inconsolable Armellini died the following year.

    Armellini published several works … the first, in 1911, based on Newtonian principles. Over his career he developed several theories and principles. He will be forever known for Armellini’s Law {in 1922 also] which determines mathematically the distances of the planets from the sun in our solar system. The key to this understanding is the Armellini constant “D” … which is 1.53 but you must start at minus 2 for Mercury. Curiosities exist in its application … from them Armellini is awarded the honour of having predicted the large asteroid/ minor planet Chiron which was not confirmed until well after his death.

  • The Martyrs of Science, or the Lives of Galileo, Tycho Brahe and Kepler – Sir David Brewster – Special Binding – 1856

    The Martyrs of Science, or the Lives of Galileo, Tycho Brahe and Kepler – Sir David Brewster – Special Binding – 1856

    Published by John Murray, London in 1856. Small octavo 216 pages after preliminaries. Bound extravagantly in full purple Morocco, with rich gilt decoration to both boards and spine, the upper board with the arms of Milton Abbat School … a fine prize. A little rubbed externally, bright throughout.

    Sir David Brewster (1781-1868) was a Scottish scientist, inventor, academic. He was Principal at St Andrews and then Edinburgh University. Newtonian devotee and master in optics (hence his interest in the subjects of this book) he discovered Brewster’s Angle and pioneered mineralogical observations with the microscope. Inventor of the stereoscopic camera and kaleidoscope. He has a crater on the Moon named after him … the ultimate accolade.

    Galileo, Tycho Brahe and Kepler need less introduction.

  • [A History of the Aclare Mine – South Australia] – Silver and a Trace of Gold – J.K. Chilman

    [A History of the Aclare Mine – South Australia] – Silver and a Trace of Gold – J.K. Chilman

    A very good copy of Special Publication No 1 celebrating 100 year of the Department of Mines and Energy, South Australia.

    Soft silvered cover, 212 pages with numerous illustrations … from photographs, sketches, maps, mine plans etc.

    From discovery in the 1840 to the end of that century … and the continuing heritage interest an extremely thorough work.

    R.K Johns in his preface … “Silver and a Trace of Gold” establishes the mood of these times and painstakingly and sympathetically traces the events connected with speculation and mining investment, the opening and closure of mining operations, and the developments in metallurgical practice and smelting of mixed metallic ores. It not only traces the history of the Aclare mine, and the Kanmantoo- Callington mining field, but has relevance to the whole mining history in the State” … a bit dry but does capture the breadth and depth of this study.

    A Mining History well presented and more … processes etc
