A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books, a red curtain covering the door, and part of the beech-coloured laminate floor.

On the left, standing up, From Crust to Core, showing a colour photo of a volcanic eruption of Etna at night. It is a long-exposure photo with numerous fiery streaks erupting from the crater.

In the middle, lying down, Confronting Consumption, showing a hardback without its dustjacket, bound in black cloth. The title and author names are printed on the spine in gold lettering, but the cover is plain black cloth.

On the right, standing up, Cohabiting Earth, showing a colour photo of a bird perched on top of a ceramic water fountain with a small column of water gently rising up out of the fountain. The background is out of focus. The bird is looking at the camera rather than drinking. I don't know what species it is, but it is predominantly an orangy-yellow with a black face and breast, and dark iridescent wing and tail feathers.

Faded 19th-century sepia photograph of Hugh Miller. He is standing, dressed in workman's overalls, his shirt-sleeves rolled up. He has bushy hair and large sideburns, and his left elbow is propped up on a carved gravestone. His right hand rests on a large stonemason's maul, and he holds a chisel in his left hand.

<p>This week's <a href="/tags/newbooks/" rel="tag">#NewBooks</a> at the library: second-hand copies of...<br>- Charles Lyell: The Years to 1841: The Revolution in Geology. Having reviewed Radical by Nature two years ago made me want to read up on other historical natural historians of this time period. There is no good recent book on the early geologist Charles Lyell. The standard is still the two books written by Leonard G. Wilson, which are the first two parts of an unfortunately unfinished trilogy. I obtained the second book some time ago, and now managed to buy the first part at a very decent price via eBay.<br>- The Feejee Mermaid and Other Essays in Natural and Unnatural History<br>- Biominerals and Fossils Through Time.

A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books and part of the beech-coloured laminate floor.

On the left, Charles Lyell: The Years to 1841: The Revolution in Geology, showing a black-and-white portrait drawn (possibly) in charcoal of a young Charles Lyell in 19th-century garb, showing him from the chest up.

In the middle, lying down, The Feejee Mermaid and Other Essays in Natural and Unnatural History, showing a drawing of an old-fashioned glass bell jar with a taxidermic oddity, a fake mermaid that has the lower body of a fish and the arms and head of a small man. The head is contorted in a grotesque scream, and he has his arms raised to cover his ears with his hands.

On the right, Biominerals and Fossils Through Time, showing a close-up colour photo of a sectioned fossil under a microscope, displaying abstract blue and gold shapes. The figure legend explains that this is a calcareous skeleton of a fossil sponge observed under a polarising microscope.

A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books and part of the beech-coloured laminate floor.

On the left, standing up, Atlas of the Galilean Satellites, showing a composite photo of four of Jupiter's large moons shown in crescent view, arranged left to right from small to large: Callisto, Ganymede, Europa, and Io, showing a tiny sulfur dioxide-rich volcanic plume in deep purple erupting from its surface.

In the middle, lying down, Fire and Mud, a very thick hardback book, showing a colour photo of an agricultural field with in the foreground the tiny figures of an ox pulling a plough, followed by a human holding the reins. The background shows various white-roofed buildings against a background of hills. The top 80% of the photo shows the sky in which an enormous eruption cloud blossoms skywards. The dust jacket explains this is an early pre-climactic eruption at 0851h, June 12, 1991. In the middle, towards the bottom, is an inset colour photo showing a house surrounded by felled trees, all covered in a thick layer of volcanic ash.

On the right, standing up, Charles Darwin, Geologist, showing a period black-and-white photo of a seated, middle-aged, balding Charles Darwin circa 1855, wearing a waistcoat. The bottom third of the photo shows a fold-out colour plate with three colourful cross-sections through the Cordilleras of the South American Andes mountains. The writing is too small to read.

A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books and part of the beech-coloured laminate floor.

On the left, Isotopes: Principles and Applications, showing a chunky hardback book with a bluish-black cover. A band of large ochre and brown pixels is running diagonally across the bottom-left corner. Though no explanation is given on the cover, this is a close-up of a colourised schematic plot that shows nuclides and their decay products

In the middle, Devil in the Mountain: A Search for the Origin of the Andes, showing a colour photo of a group of small, single-storey concrete buildings on a barren hillside with a huge mountain range with snow-covered peaks in the background. This photo is reproduced in the book, with the legend explaining that this is a small cemetery on the road to the Zongo Valley in the Cordillera Real, just north of La Paz. The peak in the background is the 6088 metre high peak of Huayna Potosi.

On the right, Bots and Beasts: What Makes Machines, Animals, and People Smart?, showing a colour photo of three figures, a small white robot, a woman, and a dog, in a grassy field facing the viewer, the out-of-focus background showing a blue sky.

Stonehenge. As painted by John Constable, 1835.

The most striking feature is the turbulent, stormy sky with sweeping dark clouds, rays of light breaking through, and possibly a rainbow.

The ancient sarsen stones and trilithons are shown in their weathered, partially ruined state.

A large fallen lintel stone lies in the foreground, emphasizing the monument's age and decay.

Tiny figures near the stones provide scale and emphasize the monument's monumentality.

<p>I always thought these were the best photos of the St Helens eruption that occurred 45 years ago today. Can you imagine being there and see that!!!</p><p>(Photos by John Christianson from Mt.

Two color landscape photos stitched together one on top of the other. Top photo shows a mountain climber in black with a red backpack and yellow socks standing on a field of snow watching a distant volcano beginning to erupt. The bottom photo, taken perhaps a minute later shows the entire volcano engulfed in ash as the cloud of ash spreads outward. The climber who was standing on the field of snow has sat down with their hand on their head in sock by the scene before them. Their long handled ice axe remains stuck in the snow next to them.

<p>James Hutton (1726–1797), father of modern geology, was born <a href="/tags/otd/" rel="tag">#OTD</a>, 14 June (NS; 3 June OS). One of the first European proponents of “deep time”, the conclusion of his 1788 paper “Theory of the Earth” has been called one of the most lyrical sentences in all of science:</p><p>The result, therefore, of our present enquiry is, that we find no vestige of a beginning,—no prospect of an end.</p><p>1/3</p><p><a href="https://www.nationalgalleries.org/art-and-artists/2808" rel="nofollow" class="ellipsis" title="www.nationalgalleries.org/art-and-artists/2808"><span class="invisible">https://</span><span class="ellipsis">www.nationalgalleries.org/art-</span><span class="invisible">and-artists/2808</span></a></p><p><a href="/tags/scottish/" rel="tag">#Scottish</a> <a href="/tags/literature/" rel="tag">#literature</a> <a href="/tags/enlightenment/" rel="tag">#Enlightenment</a> <a href="/tags/18thcentury/" rel="tag">#18thcentury</a> <a href="/tags/deeptime/" rel="tag">#DeepTime</a> <a href="/tags/science/" rel="tag">#science</a> <a href="/tags/geology/" rel="tag">#geology</a></p>

A portrait of James Hutton, painted by Sir Henry Raeburn. Oil on canvas, c. 1776. Hutton – a slim, middle-aged man, clean-shaven and with a receding hairline – sits in a plain wooden chair. His left leg is crossed over his right knee, and his hands are interlaced on his lap. He wears a brown eighteenth-century suit, with knee breeches. To his left is a table covered by a green cloth; on the table are piles of papers and a collection of rocks and fossils.

<p>This week's <a href="/tags/newbooks/" rel="tag">#NewBooks</a> at the library:<br>- For my birthday back in December, I treated myself to Mary Shelley's Frankenstein from The Folio Society.<br>- A review copy of Simon Lamb's The Oldest Rocks on Earth: A Search for the Origins of Our World from Columbia University Press (a review is forthcoming).<br>- A second-hand copy of Peter Godfrey-Smith's Darwinian Populations and Natural Selection from Oxford University Press. This one was withdrawn from the holdings of the nearby Devon Libraries, but has found a welcome home with me.<br><a href="/tags/books/" rel="tag">#Books</a> <a href="/tags/scicomm/" rel="tag">#Scicomm</a> <a href="/tags/geology/" rel="tag">#Geology</a> <a href="/tags/earthsciences/" rel="tag">#EarthSciences</a> <a href="/tags/evolution/" rel="tag">#Evolution</a> <a href="/tags/evolutionarybiology/" rel="tag">#EvolutionaryBiology</a> <a href="/tags/bookstodon/" rel="tag">#Bookstodon</a> <span class="h-card"><a href="https://fedigroups.social/@bookstodon" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@<span>bookstodon</span></a></span></p>

A photo of three books standing on a small, brown, wooden table. The out-of-focus background shows black shelves full of books and part of the beech-coloured laminate floor.

On the left, standing up, Frankenstein, showing a black silhouette of a humanoid figure in shredded clothing against what would be white rocks. The book is bound in blue cloth and is standing in front of a blue marbled slipcase.

In the middle, lying down, The Oldest Rocks on Earth, a paperback showing a colour photo of a mountainous landscape (to be specific, a view of the Makhonjwa Mountains in northwest Eswatini (formerly Swaziland), Africa.

On the right, standing up, Darwinian Populations and Natural Selection, a hardback showing drawings of ammonites on a pale pink background, with a white-bordered square with an ammonite drawing on a pale orange background in the centre.

On the left, Saurian: A Field Guide to Hell Creek, showing dark grey / blue hardcover book with a colour illustration of Tyrannosaurus rex, here reconstructed as a beefy dinosaur with a bulging skull, rather than a skinny reconstruction that shows the contours of bones.

In the middle, Extinctions: Living and Dying in the Margin of Error, showing a white hardback with a colour photo of a polar bear across the bottom and a trilobite fossil across the top.

On the right, Rock, Bone, and Ruin, showing a yellow hardback with. Each word of the title is cut out of a black-and-white photo of a rock, the bones of a tail, and a ruin (what looks to be the Colosseum) .

Like a family of giant whales, the 75-million-year-old rock formation rises from an ocean of trees on a plateau high above the Mekong River in north-east Thailand.
