  • Rare Large Sized Microscope Size – Lantern Fly – China

    Rare Large Sized Microscope Size – Lantern Fly – China

    No date or maker but this presentation was a specialty in the late Victorian / Edwardian era. Reference authority “Bracegirdle” shows a number of “outsized” examples but none quite like this.

    In modern terms known as the spotted lantern fly. The insect is on the move and a potential threat in Australia – modelling has shown that it could survive well in western and north-western Victoria. When we say a threat, it was endemic to China and Vietnam but moved into South Korea in 2006, Japan in 2009 and the USA in 2014 … so the move is on.

    Here the little blighter is beautifully preserved and presented in Canada Balsam … we know that CB was the mounters choice due its quality and the cursive narrative says so.

    A microscopical rarity outsized mount of the Spotted Lantern Fly.

  • Amsler Polar Planimeter [Measuring the area of complex irregular shapes/ boundaries] c1910

    Amsler Polar Planimeter [Measuring the area of complex irregular shapes/ boundaries] c1910

    Plush-lined fitted case some 12” long contains a polar planimeter invented by Swiss mathematician Jacob Amsler. All in very good condition and working order.

    The instrument was a revolutionary change from the complex Cartesian system base instruments used before. This device uses polar co-ordinates.

    With this device two arms are connected with a pivot both arms moving around the anchor. As the pivot moves back and forth it traces an area whose net measurement is zero. The means that the area traced by the tracer point exactly equals the area of the closed curve. The area is equivalent to 2pi X the product of the length of the tracer arm, the radius of the counting wheel and the number of revolutions of the counting wheel.

    In more modern times mathematicians apply “Green’s theorem”.

    Amsler’s radical and very useful new design

  • Strawbale Homebuilding – Alan Gray.

    Strawbale Homebuilding – Alan Gray.

    An “Earth Garden Magazine Publication” i.e. self published by Alan Gray of PO Box 2, Trentham, Victoria – love it!.

    The title more or less explains all. Octavo, perfect bound, 156 pages with numerous illustrations from original photographs of the magnificent constructions. This method may have gone out of fashion with the move towards stainless steel, glass and posh bathrooms.

    Time for a resurgence we would say – the economy monetary and environmental should be promoted by Governments and all of their cascading authorities.

    Every public servant should be made to build one – sorry if you live off the purse.

    More money and delight can be made from this book over any other
