Johnson Professor Eugene A. TeSelle Professor Richard F. Haglund Professor James P. Byrd William Buckland “The evidences afforded by the sister sciences exhibit indeed the most admirable proofs of design originally exerted at the Creation: but many who admit these proofs still doubt the continued superintendence of that intelligence, maintaining that the system of the Universe is carried on by the force of the laws originally impressed upon matter…. Such an opinion … nowhere meets with a more direct and palpable refutation, than is afforded by the subserviency of the present structure of the earth’s surface to final causes; for that structure is evidently the result of many and violent convulsions subsequent to its original formation. When therefore we perceive that the secondary causes producing these convulsions have operated at successive epochs, not blindly and at random, but with a direction to beneficial ends, we see at once the proofs of an overruling Intelligence continuing to superintend, direct, modify, and control the operation of the agents, which he originally ordained.” – The Very Reverend William Buckland (1784-1856), DD, FRS, Reader in Geology and Canon of Christ Church at the University of Oxford, President of the Geological Society of London, President of the British Association for the Advancement of Science, Dean of Westminster. -

His first employment was as a land surveyor (1). Then in 1793 he became both, canal surveyor (2), and engineer, (3) to the Somerset Coal Canal (SCC). These had guaranteed him a regular, and known, income. But this suddenly changed, when he was successively dismissed, first as surveyor, then as engineer, in 1799. He now had to find some other means of supporting himself, and the geological revelations, which he knew were so important, that he had uncovered in Somerset. In the mid-1790s, he had done some land drainage and irrigation work (4), for the chairman of the SCC, and immediately after his dismissals, was able to generate an adequate living from such work around Bath, during a period of very high rainfall. -

Newsletter of the History of Geology Group of the Geological Society
HOGG Newsletter of the History of Geology Group of The Geological Society Number 68 February 2020 Front cover WILLIAM AUGUSTUS EDMOND USSHER (1849‒1920), the centenary of whose death is remembered this year. Born in County Galway, Ireland in 1849, Ussher joined the Geological Survey of Great Britain (now British Geological Survey) in 1868 and spent his whole career (retiring in 1909) as a field and mapping surveyor. He is best known for his work in the south-west of England (Cornwall, Devon, Somerset), particularly his work on the Devonian, Carboniferous and Triassic strata. In 1894, he was awarded the Geological Society’s Murchison Medal. Many Survey maps and memoirs bear his name as does the Ussher Society founded in 1962 as a focus for geological research in south-west England. Originally published under the title Proceedings of the Ussher Society, its journal was renamed Geoscience in South-West England in 1998. Sources Anon. 1920. Obituary of Mr W. A. E. Ussher.

It has the shape of a shallow-dipping slab or sheet up to a few kilometres thick that was exhumed from the subduction zone and emplaced into the accretionary complex to the northwest. Today the top boundary of the slab is commonly a thrust that was originally a low-angle normal fault at its top in the subduction zone; above it is an accretionary complex and a unit of high-grade gneisses. -
Letters from Charles Lyell and Adam Sedgwick to H. B. Tristram
LETTERS FROM CHARLES LYELL AND ADAM SEDGWICK TO H. B. TRISTRAM By S. I. TOMKEIEFF SOME years ago in Durham city, I bought a copy of the ninth edition of LyelPs Principles of Geology (1853).* At the back of the front cover it bore the ex libris of H. B. Tristram and an inscription stating that the book was presented to H. B. Tristram by the East Durham Book Hawking Society. Between the pages of this book I found three letters addressed to H. B. Tristram—two from Lyell and one from Sedgwick. These letters, as far as I know, have never been published. The name of Tristram does not occur in Life, letters and journals of Sir Charles Lyell,2 books on Lyell by T. G. Bonney3 and E. Bailey,4 and in Life and letters of Sedgwick.5 Thus the publication of these letters may be of historical interest. I have consulted Lord Lyell and his mother, Lady Lyell, who have no objection to the letters being published, but I failed to get in touch with the descendants of H. B. Tristram, or Sedgwick. The three letters contain no private matter and their publication can offend no one. The Reverend Henry Bower Tristram (182 2-1906), divine and naturalist, obtained his B.A. and M.A. at Oxford, in 1849 he became Rector at Castle Eden, Co. Durham, and in 1870 Canon of Durham Cathedral. In 1855-1857 he travelled in Algeria, the Sahara and later in Palestine and Egypt. In i860 he published a book, The Great Sahara. -
A Study of Saline Incursion Across an Inter-Tidal Zone on Anglesey, Wales
A study of saline incursion across an inter‐tidal zone on Anglesey, Wales using airborne conductivity data David Beamish British Geological Survey, Keyworth, Nottingham, NG12 5GG, UK. Near Surface Geophysics, 2012, 10, 171-184 Corresponding author: David Beamish British Geological Survey, Keyworth, Nottingham, NG12 5GG, UK Email: [email protected]. Tel: +44(0)115 936 3432 Fax: +44(0)115 936 3261 Right running head: inter-tidal zone, saline incursion Anglesey Wales, airborne ABSTRACT This study considers fixed-wing airborne electromagnetic data obtained by a recent high- resolution airborne geophysical survey across the island of Anglesey, Wales. The survey detected an extensive (~10 km in length) highly conductive, near-surface zone across low- lying marsh and salt-marsh areas. The four frequency electromagnetic survey data enable a continuous assessment of subsurface conductivity variations across the inter-tidal zone and onshore into the Holocene sediments and bedrock. Inshore sea-water conductivities exceed 2000 mS/m but reduce across sandbank areas to a range of values, typically exceeding 500 mS/m. Saline incursion onshore is observed largely at lower values and at a range of scales extending to over 10 km. Within defined salt-marsh areas, a main front of near-surface incursion can be mapped and extends several hundred metres inshore. The main body of subsurface saltwater incursion is largely confined to a trough containing Holocene deposits above Upper Carboniferous (Coal) Measures which were historically mined. The main conductive zone becomes more compact, both vertically and laterally, with increasing distance inland. Modelling of the data indicates that, onshore, the major concentrations of dissolved solids are confined to the upper 30 m within undulating subsurface zones. -

Princess of Palaeontology
millennium essay Princess of palaeontology Mary Anning came from humble origins to find fame as a fossil hunter on England’s south coast. Others took credit for her discoveries but it was said of her that she understood more of the science than “anyone else in the kingdom”. Crispin Tickell his year is the bicentenary of the birth of Mary Anning of Lyme Regis. She Thas become famous first as the discov- erer — and saleswoman — of the exotic fossil creatures of the Lower Jurassic; and secondly as the prettified heroine of many children’s books, sometimes identified with she “who sells sea-shells on the sea shore”. A recent MUSEUM, LONDON HISTORY NATURAL symposium in her honour at Lyme Regis brought together palaeontologists, histori- ans and sociologists of science. Anning was the daughter of a carpenter or cabinet-maker. Although she wrote that she was illiterate, this was far from so. Her letters were clearly written, and she is said to have DEPT GEOLOGY, NATIONAL MUSEUM OF WALES NATIONAL DEPT GEOLOGY, taught herself French in order to read Georges Cuvier. Her father collected and sold ‘curiosi- ties’ from the Dorset cliffs and beaches, and when he died in 1810 he left her, his son Joseph and his widow Molly the rudiments of a busi- ness. It seems to have been Joseph who uncov- ered the head of the famous ichthyosaur, which he and Mary excavated and sold. It requires a major effort of the imagina- tion to think back into the mental world of the 1820s. How did she interpret the world around her, and the place in it of the fossils she found? At one level far from hers, the concept of deep time was just beginning to take hold.
