  • Sir James Alfred Ewing, K.C.B., M.A., D.Sc, LL.D., F.R.S
    150 Obituary Notices. Sir James Alfred Ewing, K.C.B., M.A., D.Sc, LL.D., F.R.S. JAMES ALFRED EWING, a great engineer, scientific man, and charming Scot, was distinguished in many fields of activity. Born in 1855 at Dundee, where his father was a minister of the Free Church of Scotland, he grew up in an intellectual and spiritual atmosphere in which his early education was greatly influenced by his mother, whose critical taste in letters was passed on to her children. From Dundee High School Ewing proceeded in the early seventies to the University of Edinburgh, where his great ability soon manifested itself in the classes of Tait and Fleeming Jenkin, the latter of whom brought him into touch with Sir William Thomson (afterwards Lord Kelvin), then engaged in the development of submarine telegraph cables, an introduction which led to Ewing taking part in three cable-laying voyages to Brazil and the River Plate. Fleeming Jenkin was a man of wide culture, and his literary and scientific circle included Ewing and another young student, Robert Louis Stevenson, then at the commence- ment of an engineering training, soon to be abandoned for a literary career of the greatest distinction, the beginnings of which have been happily described by Ewing in "The Fleeming Jenkins and Robert Louis Steven- son." In 1878, at the early age of twenty-three, Ewing went to Japan as Professor of Mechanical Engineering in the University of Tokyo, a post which he occupied for five years, and there he made his classical researches in the widely different fields of magnetism and seismology.

  • Sess. Professor Andrew Jamieson, M.Inst
    334 Proceedings of the Royal Society of Edinburgh. [Sess. Professor Andrew Jamieson, M.Inst.C.E. By Mr J. Wilson. (Read January 20, 1913.) PROFESSOR JAMIESON, M.Inst.C.E., whose death took place on the 4th December 1912, at his residence, 16 Rosslyn Terrace, Kelvinside, Glasgow, W., was well known throughout the country as a consulting engineer and as the author of a large number of standard text-books on electrical and engineering subjects. He was elected to the Fellowship of the Royal Society of Edinburgh in 1882. Professor Jamieson, who was the eldest son of the late Rev. George Jamieson, D.D., of Old Machar Cathedral, Aberdeen, was born at Grange, Banffshire, in 1849, and received his education at the Gymnasium, Old Aberdeen, and at Aberdeen University. His apprenticeship was served with Messrs Hall, Russel & Co., marine engineers and shipbuilders, Aberdeen Ironwork. He afterwards entered the service of the Great North of Scotland Railway Company, ultimately attaining the position of chief draughtsman in the loco, and carriage department. When only twenty-three years of age he was appointed assistant to Sir William Thomson (Lord Kelvin) and Professor Fleeming Jenkin, who placed him in charge of the testing staff, to supervise the manufacture of the submarine cables at the Woolwich works of Messrs Siemens Bros. Then followed several years during which Mr Jamieson was mostly abroad. For two years he acted as chief electrical assistant to Thomson and Jenkin, along the coast of Brazil, for the Western Brazilian, and Platino-Brazilian Companies. On returning to this country, the late Sir John Pender and Sir James Anderson appointed him chief electrician to the Eastern Telegraph Company, and he was sent to the Mediterranean to super- intend the laying of the Marseilles-Malta cable.

    GENERAL ARTICLE Weldon’s Search for a Direct Proof of Natural Selection and the Tortuous Path to the Neo-Darwinian Synthesis Amitabh Joshi WFRWeldonfirst clearly formulated the principles of nat- ural selection in terms of what would have to be observed in natural populations in order to conclude that natural selec- tion was, indeed, acting in the manner proposed by Darwin.

  • The English-Speaking Aristophanes and the Languages of Class Snobbery 1650-1914
    Pre-print of Hall, E. in Aristophanes in Performance (Legenda 2005) The English-Speaking Aristophanes and the Languages of Class Snobbery 1650-1914 Edith Hall Introduction In previous chapters it has been seen that as early as the 1650s an Irishman could use Aristophanes to criticise English imperialism, while by the early 19th century the possibility was being explored in France of staging a topical adaptation of Aristophanes. In 1817, moreover, Eugene Scribe could base his vaudeville show Les Comices d’Athènes on Ecclesiazusae. Aristophanes became an important figure for German Romantics, including Hegel, after Friedrich von Schlegel had in 1794 published his fine essay on the aesthetic value of Greek comedy. There von Schlegel proposed that the Romantic ideals of Freedom and Joy (Freiheit, Freude) are integral to all art; since von Schlegel regarded comedy as containing them to the highest degree, for him it was the most democratic of all art forms. Aristophanic comedy made a fundamental contribution to his theory of a popular genre with emancipatory potential. One result of the philosophical interest in Aristophanes was that in the early decades of the 18th century, until the 1848 revolution, the German theatre itself felt the impact of the ancient comic writer: topical Lustspiele displayed interest in his plays, which provided a model for German poets longing for a political comedy, for example the remarkable satirical trilogy Napoleon by Friedrich Rückert (1815-18). This international context illuminates the experiences undergone by Aristophanic comedy in England, and what became known as Britain consequent upon the 1707 Act of Union.

  • Tragedy After Darwin by Manya Lempert a Dissertation Submitted In
    Tragedy after Darwin by Manya Lempert A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in English in the Graduate Division of the University of California, Berkeley Committee in charge: Professor Dorothy Hale, Chair Professor Ann Banfield Professor Catherine Gallagher Professor Barry Stroud Summer 2015 Abstract Tragedy after Darwin by Manya Lempert Doctor of Philosophy in English University of California, Berkeley Professor Dorothy Hale, Chair Tragedy after Darwin is the first study to recognize novelistic tragedy as a sub-genre of British and European modernism. I argue that in response to secularizing science, authors across Europe revive the worldview of the ancient tragedians. Hardy, Woolf, Pessoa, Camus, and Beckett picture a Darwinian natural world that has taken the gods’ place as tragic antagonist. If Greek tragic drama communicated the amorality of the cosmos via its divinities and its plots, the novel does so via its characters’ confrontations with an atheistic nature alien to redemptive narrative. While the critical consensus is that Darwinism, secularization, and modernist fiction itself spell the “death of tragedy,” I understand these writers’ oft-cited rejection of teleological form and their aesthetics of the momentary to be responses to Darwinism and expressions of their tragic philosophy: characters’ short-lived moments of being stand in insoluble conflict with the expansive time of natural and cosmological history. The fiction in this study adopts an anti-Aristotelian view of tragedy, in which character is not fate; character is instead the victim, the casualty, of fate. And just as the Greek tragedians depict externally wrought necessity that is also divorced from mercy, from justice, from theodicy, Darwin’s natural selection adapts species to their environments, preserving and destroying organisms, with no conscious volition and no further end in mind – only because of chance differences among them.

  • Aspects of the Life and Work of Peter Guthrie Tait, FRSE1
    Aspects of the Life and Work of Peter Guthrie Tait, FRSE1 An essay by Dr. Chris Pritchard, PhD, FIMA, McLaren High School, Callander, Scotland. Peter Guthrie Tait was born in Dalkeith in 1831. Upon the death of his father when he was just six his mother took him and his two sisters to live in Edinburgh with her brother. Here in his uncle’s house he was encouraged to dabble in photography and astronomy. We know that at the age of thirteen he was making nightly observations of the positions of Jupiter's satellites. By this time he had entered the Edinburgh Academy. Fleeming Jenkin2 was a member of the same class, James Clerk Maxwell in the class above. The friendship which developed between Maxwell and Tait during their school days would last throughout Maxwell’s relatively short life. If there was a competitive element to that friendship, encouraged by the school’s awarding of the mathematics prize to Tait in 1846 and to Maxwell the following year then it was certainly not apparent. They exchanged drafts of papers they were writing in their teens and we know that Tait retained his annotated copies of Maxwell’s early geometrical papers for many years. At sixteen both young men went up to their local university but after just one session Tait moved on to Peterhouse, Cambridge, from where he graduated as Senior Wrangler in 1852. When Maxwell eventually moved to Cambridge it was in Tait’s college that he initially enrolled despite being advised by Forbes3 to enter Trinity. Within a couple of years of graduation Tait had been offered a mathematics chair at Queen’s College, Belfast.

  • Aristophanes in Performance 421 BC–AD 2007
    an offprint from Aristophanes in Performance 421 BC–AD 2007 Peace, Birds and Frogs ❖ EDITED BY EDITH HALL AND AMANDA WRIGLEY Modern Humanities Research Association and Maney Publishing Legenda: Oxford, 2007 C H A P T E R 16 ❖ A Poet without ‘Gravity’: Aristophanes on the Italian Stage Francesca Schironi Since the beginning of the twentieth century, Aristophanes has enjoyed a certain public profile: I have counted at least seventy-four official productions that have taken place in Italy since 1911. The most popular play by far seems to be Birds, which has taken the stage in sixteen different productions. Clouds is also reasonably popular, having been staged in twelve different productions. There have also been some interesting rewritings and pastiches of more than one play. But particularly striking is the relative infrequency with which Frogs — in my view one of Aristophanes’ most engaging comedies — has been produced: it has only seen public performance twice, in 1976 and in 2002.1 Indeed, it is one of those two productions of Frogs that attracted my attention: the most recent one, directed by Luca Ronconi at Syracuse in May 2002. As most people know by now, this performance excited many discussions, in Italy,2 as well as abroad,3 because of widespread suspicion that it had incurred censorship at the hands of Berlusconi’s government. I would like to reconsider this episode, not only because it is both striking and ambiguous, but above all because on closer inspection it seems to me a particularly good illustration of how theatre, and in particular ancient Greek and Roman theatre, ‘works’ in Italy.
