Natural History

Fossil Fern – Lune River Tasmania – Early Jurassic Forest circa 182 million years old.

A nice slice of petrified tree fern from the Lune River area deep in the southern reached of Tasmania.

The dating of the examples in this location to the middle of the early Jurassic Period (182 Ma) was by isotopic measurements on zircons found in the volcanic sandstone hosting the fossils (Bromfield et al 2007). Also refer the excellent guide by P. Manchester.

Weighing 70gm and 16cm by 5cm.

This region is the area of the world where these plants developed. Twelve tree paratypes (arborescent) ferns and one bracken-like (rhizomatous) fern have been studied in the region. All of the tree ferns belong to the genus Osmundacaulis. This example shows clear and tight trachioles

These plants evolved in this region, the Australian portion of Pangea, all that time ago. Gradually they have spread elsewhere and appear in North-west USA … examples were only discovered in Eurasia in the year 2000.

Published in the December after the conference this is the Proceeding of the Royal Society of Tasmania, representing Volume 143 Parts I and II.

Part I features … Climate trends at Macquarie Island; Exploitation of the marine ecosystem; Biological systems at Prince Edward Island; Terrestrial vegetation changes at Macquarie and Heard islands; Invasive species etc

Part II features … Orchids of Macquarie island; Freshwater diatoms; Antarctic vignettes Shackleton; Foraminifera ad paleoenvironment of Late Pleistocene sands, White Rock Point, Southeastern Tasmania; HMS Beagle in Tasmanian waters.

We particularly like the foram papers by Quilty et al … the site being round South Arm … and the tracking of the Beagle is up right up our street … or Ocean.

Antarctic forum – wish we had been there.

Rare Microscope Slide by Harry Webb – Transverse Section of Mistletoe – c1860

Harry Webb (1816-1866) was a professional mounter who lived in George Street, Balsall Heath, Birmingham England. His initials are embedded in the custom-made decorative slide papers.

A nice transverse section of the mistletoe stem.

There is a brief reference to Harry Webb in the key work by Brian Bracegirdle – Microscopical Mounts and Mounters (page 100) and an unattributed example (Page 39-P). we have this information from a later reviewer who knows their stuff – but we struggle to agree that the example shown in the book is from HW.

Webb’s work featured in several international shows and he is thought to have been awarded at least one prize. He was recommended by top line microscope makers. Unfortunately, something went very wrong and he took his life drinking phenol – which would not be a nice way to go.

Rare maker with definitive slide papers – 165 years old!

Erect-Crested Penguin – Lance Richdale – 1950

This is an offprint from the “The Emu” the then official organ of the Royal Australasian Ornithologist’s Union.

The point of this item is that since 1940 the population of this species of Penguin has been in decline and is now categorised as endangered. They nest on the Bounty and Antipodes Islands. Previously on the Auckland, Campbell etc Islands and the Otago Peninsula but no longer. At the time of writing the report Richdale was probably observing the last Otago nesters …

Typical offprint faded card covers, 18 pages with quite a few images from photographs of the beautifully crested penguins. Maybe there are some clues in here as to what will soon lead to further reductions in breeding.

Lance Richdale was a big individual in the bird world – he was a Fulbright Fellow at Cornell and a Nuffield Fellow in his field – later in life he spent time at the Zoological Society in London. Author of the Sexual Behavior of Penguins.

Erect-Crested doing it tough in the far reaches of the Southern Ocean.

Extra special, almost unheard of, we still have the original “printed directions” with schematic of the microscope and accessories. Put back together by someone else with Sellotape

A super example of this upmarket drum style brass microscope.

Steward’s Catalogue goes on … “For Utility, Portability, and Cheapness, this Instrument is not equalled; and to convey some idea of its power, a Microscopic Photograph of the “Trial of Pickwick”, containing upwards 9,000 letters, and occupying the space of a pin’s head, when placed under this Instrument every word can be rad with the greatest ease”

Siluria – The History of the Oldest Known Rocks Containing Organic Remains; with a Brief Sketch of the Distribution of Gold Over the Earth – Sir Roderick Impey Murchison – First Edition 1854

A very good copy of the first edition of this most important scientific work, published by John Murray, London in 1854.

Thick Royal Octavo, bound in full leather, separate green leather title label, gilt decorations to compartments on the spine. Marbled end papers with the marbling continuing to the page edges, boards with decorative edge gilding to front, back and edge. 523 pages after preliminaries, followed by 37 lithographed plates of the principal Silurian fossils, with descriptive letterpress, folding world map at page 475. Separate folding Geological Map of the Silurian Rocks in pocket at rear.

The coloured folding map (53cm by 43cm) published under Murray drawn by J.W. Lowry and lithographed by Vincent Brooks is a first edition dated 1853 of the Geological Map of the Silurian Rocks and overlying formations as developed in Wales and the Adjacent Parts of England, chiefly prepared for the Geological Survey of Great Britain. It is in very good condition, cloth backed likely at the time of binding.

The plates are well executed, many by James De Carle Sowerby (1787-1872) eldest son of the great James Sowerby and founder of the Royal Botanical Society.

Roderick Impey Murchison (1792-1871) was an incredible individual. Scottish born, born into a wealthy, and was sent to Durham for schooling at the age of 7, after the death of his father. He joined the military and at 16 saw action in the Peninsula War. In 1818 he met Sir Humphrey Davy who persuaded him to pursue science. He joined the Royal Geological Society … his colleagues included, William Buckland, Charles Lyell and Darwin. He worked with Lyell on the geology of the Alps. In the 1830’s he did much research in and around the England Wales border and through that established the Silurian system and then went on to categorise the Devonian and Permian systems.

In 1845 Murchison new several Cornish miners who were off to Australia to explore for gold. They sent back samples … so Murchison new of the discovery of gold in Australia before Edward Hargraves.

He won many distinguished awards including the Royal Society Copley Medal, the Geological Society Wollaston Medal, and the Edinburgh Brisbane Medal (Another Australian connection). Also, many overseas awards. He was President of the Royal Geographical Society on four separate occasions, importantly he was one of the founders in 1830.

A crater on the Moon is named after him as well as geographical features in Greenland, USA, Canada, Antarctica, Uganda. In Australia the Murchison River with its tributaries named, Roderick and Impey.
