It is requested that all letters and communications to the Secretaries, and presents to the Society,x may be addressed to the House of the Geological Society, No. 20, Bedford Street, Covent Garden, London. NOTICE. THE Council of the Geological Society have recently taken upon themselves the charge and management of the publication of their TRANSACTIONS, for the purpose of reducing the price, and thereby promoting the diffusion of Geological information. With this view they have adopted a page more full than that of the preceding volumes, and have employed Lithographic Plates instead of Engravings on Copper, wherever the substitution could be effected without injury to the correct illustration of the subjects represented. As the Transactions of the Geological Society will thus assume a form in some measure new, the Council, for the convenience of purchasers, have deter­ mined to commence a New Series of volumes;—that now published being Volume I. Second Series. LONDON, July 3, 1822. .

  • Geotourism and Geoconservation on the Isle of Wight, UK: Balancing Science with Commerce
    Carpenter: Rocky start of Dinosaur National Monument… Geoconservation Research Original Article Geotourism and Geoconservation on the Isle of Wight, UK: Balancing Science with Commerce Martin I. Simpson Lansdowne, Military Rd, Chale, Isle of Wight, PO38 2HH, UK. Abstract The Isle of Wight has a rich and varied geological heritage which attracts scientists, tourists and fossil collectors, both private and commercial. Each party has a role to play in geoconservation and geotourism, but a policy on the long term curation of scientifically important specimens is essential to prevent future conflicts. A new code of conduct is recommended, based on the one adopted on the Jurassic Coast of Dorset. I have spent over 40 years living on the Island and working in the tourist industry running geology field-trips for both academics and tourists, and managing one of the longest running geological gift shops. I see the geological heritage and fossil sites as valuable geotourism assets, and envisage no problems with respect to the scientifically important material provided that a clear collecting policy is adopted, and the local museum generates funding to ensure that significant finds remain on the Island. A positive attitude is recommended in view of past experiences. Corresponding Author: Martin I. Simpson Lansdowne, Military Rd, Chale, Isle of Wight, PO38 2HH, UK.

  • James Hutton's Reputation Among Geologists in the Late Eighteenth and Nineteenth Centuries
    The Geological Society of America Memoir 216 Revising the Revisions: James Hutton’s Reputation among Geologists in the Late Eighteenth and Nineteenth Centuries A. M. Celâl Şengör* İTÜ Avrasya Yerbilimleri Enstitüsü ve Maden Fakültesi, Jeoloji Bölümü, Ayazağa 34469 İstanbul, Turkey ABSTRACT A recent fad in the historiography of geology is to consider the Scottish polymath James Hutton’s Theory of the Earth the last of the “theories of the earth” genre of publications that had begun developing in the seventeenth century and to regard it as something behind the times already in the late eighteenth century and which was subsequently remembered only because some later geologists, particularly Hutton’s countryman Sir Archibald Geikie, found it convenient to represent it as a precursor of the prevailing opinions of the day. By contrast, the available documentation, pub- lished and unpublished, shows that Hutton’s theory was considered as something completely new by his contemporaries, very different from anything that preceded it, whether they agreed with him or not, and that it was widely discussed both in his own country and abroad—from St. Petersburg through Europe to New York. By the end of the third decade in the nineteenth century, many very respectable geologists began seeing in him “the father of modern geology” even before Sir Archibald was born (in 1835). Before long, even popular books on geology and general encyclopedias began spreading the same conviction. A review of the geological literature of the late eighteenth and the nineteenth centuries shows that Hutton was not only remembered, but his ideas were in fact considered part of the current science and discussed accord- ingly.

  • Imperfect Notion at Present. the Faculty of Medical Professors Were
    Letter I 15th July 1836 My dear Sharpey, The day before yesterday I got a summons from Carswell' to see him in some way or other as soon as possible and when I called on him I found you were the subject of conversation. From what he said I think there is every likelihood ofyour being chosen by the Council of the London University, but of course we can have but a very imperfect notion at present. The Faculty of Medical professors were to meet today to discuss the matter & Carswell says that their suggestion is very generally attended to by the Council. Mayo2 seemed to have an inclination to offer himself and Grainger3 is I suppose a candidate but Carswell seems to think that others as well as he is himselfwill be for having you. I need not say what tumult of feelings all this raised in my mind. The emoluments ofthe situation appear to be nearly £800 a year and you will deliver your lectures in much more advantageous circumstances there than you can do in Edinburgh. [I]t increases your chances of the Edinburgh chair4 and of preferment in every way and as far as I can see is most advantageous for you. I wrote you thus promptly in case it were possible for me to be of any use to you in this matter. Write me at all events and let me know what you are thinking ofthe matter. I weary to hear something ofSurgeons Square.5 Indeed I feel melancholy whenever I think of it.

  • The Correspondence Between Charles Lyell and His Family and Gideon Algernon Mantell: 1821 - 1852
    THE CORRESPONDENCE BETWEEN CHARLES LYELL AND HIS FAMILY AND GIDEON ALGERNON MANTELL: 1821 - 1852 Transcribed and Annotated by Alan John Wennerbom A supplementary volume to the thesis Charles Lyell and Gideon Mantell, 1821-1852: Their Quest for Elite Status in English Geology, submitted in fulfilment of the requirements for the Degree of Doctor of Philosophy Unit for the History University of Sydney and Philosophy of Science February 1999 1 Charles Lyell to G. A. Mantell 29 Norfolk St. Strand Nov 3 1821. My dear Sir Your letter was forwarded to me here from the country some days since wh I have delayed answering in the hopes of being able to procure you some little information. I dispatched my packet to you as soon as I returned from my Sussex tour, I believe on the 11 th. or 12 th.of Octr. as you will see I suppose by my letter.1 They did not reach you it seems till the 25th. A fortnight from Southton to Lewes! This was unlucky, for had I known how much they w.d interest you I would have forwarded you a large collection at Stonesfield. Will you endeavour to ascertain the cause of the Waggon’s delay, for it strikes me as so careless that I am afraid to ask you to send any to Bartley Lodge – Southhampton2 lest they sh.d be lost on the way. If you can send me any be sure they are duplicates & only such as you have or can procure in abundance, for as I only wish them for instruction & have no choice cabinet, you would throw away your pearls.

  • HISTORY of SCIENCE and TECHNOLOGY: SERIES THREE: Part 1, Babbage
    HISTORY OF SCIENCE AND TECHNOLOGY: SERIES THREE: Part 1, Babbage THE HISTORY OF SCIENCE AND TECHNOLOGY Series Three: The Papers of Charles Babbage, 1791-1871 Part 1: Correspondence and Scientific Papers from the British Library, London Contents listing PUBLISHER'S NOTE BRIEF BIOGRAPHY BRIEF BIBLIOGRAPHY CONTENTS OF REELS LISTING BY CORRESPONDENT HISTORY OF SCIENCE AND TECHNOLOGY: SERIES THREE: Part 1, Babbage Publisher's Note “The idea of a digital computer is an old one. ... Babbage had all the essential ideas....” Alan Turing Alan Turing’s comment confirms the importance of Babbage to the History of Computing. Elected a Fellow of the Royal Society (aged 24) in 1816 - the same year in which Mary Shelley’s Frankenstein was written - Babbage showed that a machine could be created which could replicate certain areas of human thought. Babbage designed first the Difference Engine (an automatic mechanical calculating machine) and then the Analytical Engine (a pioneer digital computer). His designs included a central processing unit (“the Mill”), memory (“the Store”), variables, operators and a printer to output conclusions. The design was one thing, actually constructing the machines with the available technology proved to be extremely difficult. Notwithstanding substantial grants from the Royal Society and the British Government Babbage failed to create either. That glory was left to the Swedish printer, Georg Scheutz, who won a gold medal at the Paris Exhibition for constructing the Difference Engine. A close friend and collaborator in much of his work was Augusta Ada Byron, later the Countess of Lovelace, who was the only child of Lord Byron. She was confident of the importance of the machine, stating that “We may most aptly say that the Analytical Engine weaves algebraical patterns just as the Jacquard loom weaves flowers and leaves.” The metaphor was appropriate, for Babbage used a card reader inspired by the punched cards used on Jacquard loom.

  • A Guide to Notes and Citations
    A GUIDE TO NOTES AND CITATIONS All items in the Somerville Collection deposited in the Bodleian Library are arranged by a shelf number and a filing code as follows: 'Dep' plus 'b.205' or 'c.NNN', where NNN = 351-378. Since the designation 'Dep.' is common to all items, it is omitted in the citations, which are thus made in this form: 'c.359,17,MSIF-3', followed by the identification of the item and its date, if any. The 'c.359' represents the shelf-mark. The '17' is a box number. 'MSIF' is a code identifying the nature of the contents of the box, e.g., inner family papers. The last number, '3', identifies the folder in which the item is located. Other abbreviations used are: MS - Mary Somerville WS - William Somerville TS - The Reverend Dr. Thomas Somerville WG - Woronzow Greig Martha S - Martha Charters Somerville Mary CS - Mary Charlotte Somerville OCPS - On the Connexion of the Physical Sciences (various editions, each identified by date) PR - Personal Recollections, from Early Life to Old Age, of Mary Somerville, with Selections from her Correspondence (Lon­ don, 1873) Lit.

Superficial praise – Part I.Sprawozdania Archeologiczne 68, 345-403. This paper explores themes Dawid Kobiałka raised in his polemic discussion, “Against Gandalf the Grey: towards a Sherlockian Reading of the History of Archaeological Thought,” specifically the role excavation plays in the discipline, thereby shaping narratives of surface and appearance, parallels between archaeology and detective fiction, and ultimately of scholarship. By digging below the surface of these narratives and dissecting their his- tory, revealing the relations between archaeology and such disciplines as history and philology, and some of the metaphors held in common by any number of scientific disciplines, we come to critically examine the meta- physical assumptions of both the discipline itself potential “radical” approaches to it. Keywords: “radical” archaeology; archaeological metaphysics; archaeology and detectives; archaeology and philology; archaeology and “autopsia”; history of archaeology Received: 26.09.2015; Revised: 06.04.2016; Accepted: 11.04.2016 INTRO I have written the following response to the… superficial (?) way Dawid Kobiałka’s polemic discussion, “Against Gandalf the Grey: towards a Sherlockian Reading of the His- tory of Archaeological Thought” (Kobiałka 2014) addresses a number of issues I’ve been examining, including the history of archaeology, archaeology and detectives, archaeologi- cal metaphysics and hermeneutics. * [email protected] 346 Geoff Carver The first point I would like to note is a reference (Kobiałka 2014, 424) not to Tolkien’s original but to the filmed version of The Lord of the Rings.
