Robert McNeill Alexander. 7 July 1934—21 March 2016

Neill Alexander graduated in natural sciences at the University of Cambridge in 1955. After a PhD at Cambridge and a lecturership at the University College of North Wales in Bangor, he was appointed to the chair of the Department of Pure and Applied Zoology at the University of Leeds in 1969. At that stage, he switched his research interests abruptly from fishes to the mechanics of legged locomotion. He conducted experiments with a variety of mammals, calculating forces, stresses and strains in muscle fibres, bones and tendons. His speciality became the application of mathematical models to animal locomotion, including repurposing the Froude number, devised by the Victorian engineer William Froude (FRS 1870) for use with ships, to estimate the speed of dinosaurs based on the spacing of their fossil footprints. Subsequent work included modelling the optimization of mammal performance and the minimization of energy costs. In 1992, following an announcement that London Zoo would have to close as a result of shortage of funds, Neill was appointed secretary of the Zoological Society of London. During the period of his secretaryship, the Society's finances recovered, with both its zoos (London and Whipsnade) breaking even in 1993 and the Society returning a surplus in each subsequent year. Neill was awarded the CBE in 2000. The National Portrait Gallery holds his portrait by John Arnison.

Genetic insights into the management and conservation of Arctic charr in North Wales

Aquatic species throughout the world are threatened by extinction in many parts of their range, particularly in their most southerly distributions. Arctic charr (Salvelinus alpinus) is a Holarctic species with a distribution that includes the glacial lakes of North Wales, towards it southern limit. To date, no genetic studies have been conducted to determine the genetic health of the three remaining native Arctic charr populations in North Wales, despite exposure to stocking and adverse environmental and ecological conditions. We used seven microsatellite loci to determine whether: 1) genetic differentiation existed between native populations; 2) translocated populations from Llyn Peris were genetically similar to the historically connected Llyn Padarn population; and 3) hatchery supplementation negatively impacted genetic diversity in Llyn Padarn. All three native populations retained their genetic integrity, with Llyn Bodlyn showing high levels of divergence (FST = 0.26 ± 0.02SD) as well as low genetic diversity (HO 0.30) compared to remaining populations (HO 0.64 ± 0.14SD). Although evidence suggests that stocking increased the effective population size of Llyn Padarn in the short term without impacting genetic diversity, the long term effects of such practices are yet to be seen. Results provide baseline data for conservation management, and highlight the need for protection of small isolated populations that are being negatively impacted by the processes of genetic drift due to escalating anthropogenic pressures. Continual monitoring of both Arctic charr and their habitats using a combination of methods will increase the likelihood that these threatened and iconic populations will persist in the future.

A Tale of Two Bridges: The Poetry and Politics of Infrastructure in Nineteenth-Century Wales

Drawing on Brian Larkin’s concept of ‘infrastructural poetics’, this article considers and compares a selection of English- and Welsh-language poems, by writers including Eliza Mary Hamilton, Frederick Faber, Richard Llwyd, and Eben Fardd, about two nineteenth-century infrastructures that transformed North Wales and Great Britain’s relationship to Ireland: the Menai Suspension Bridge (1826), and the Britannia Tubular Bridge (1850). I argue that these non-canonical poems complement perspectives derived from parliamentary records, official reports, technical planning documents, scientific manuals, and journalism, enhancing our understanding of the nineteenth-century infrastructural imagination. Specifically, building on the association of infrastructural development and modernity, I explore how the poems under discussion participate in nineteenth-century negotiations about Wales’s place and future in the United Kingdom, and how these negotiations evolved between 1819 and 1852. I show that, although Wales was the site of impressive engineering feats and accelerating industrial extraction, English-language poems present the Menai Bridge in picturesque terms, drawing on popular images of the Celtic fringe that evoke timeless, ideal beauty. Anglophone verse about Britannia Bridge, by contrast, focuses explicitly on the infrastructure’s technological modernity but claims it as an English landmark. Both strategies, I suggest, effect an erasure of Wales – as a distinct cultural and political entity – from a future conceived as Anglo-British. Poems written in Welsh, and the work of Welsh writers in English, complicate this picture, not because they reject British nationalism and imperialism, but because they seek to embed a modern Welsh nation more centrally within those political and ideological frameworks.

397 Seasonal Variation in Acute Cholecystitis; An Analysis to Predict Resources Allocation

Background Acute cholecystitis accounts for 20% of Emergency General Surgical admissions. The concept of seasonal variation is still a developing concept in surgical literature. Whether acute cholecystitis also follows a seasonal trend remains to be established. Aim Given the struggle healthcare system has been facing towards resource and staff allocation to deliver best possible patient care, we thought this may be a step forward to predict North Wales demand of resources seasonally and make appropriate arrangements ahead of time. Method We performed a retrospective analysis of patients across North Wales who had a discharging diagnosis of acute cholecystitis from January 2010 to December 2019. Chi-square goodness-of-fit test was used to analyse seasonality of acute cholecystitis adjusting for variation in number of days between seasons. The number of days for seasons were taken as 92, 92, 91, and 90.25 for spring, summer, fall, and winter, respectively. Results Overall, 4100 patients presented to the three hospitals across North Wales with acute cholecystitis during the study period. The frequency of hospital admissions varied between months (minimum February n = 302, maximum July n = 373) and seasons (minimum winter n = 971, maximum spring n = 1067). After applying chi-square goodness-of-fit test to check significant seasonality, we did not find any significant seasonal variation in acute cholecystitis (p-value = 0.262). Conclusions Our data failed to show any significant seasonal variation in patients presenting with acute cholecystitis in North Wales. We recommend prospective collection of data at national level to validate our results.

1476 North Wales Vascular Surgery Zoom Webinar Teaching Programme for Medical Students and Junior Doctors

Aim Surgical Education is now more widely delivered on virtual platforms due to the COVID-19 pandemic. Due to centralisation of Vascular Surgery services in North Wales to Glan Clwyd Hospital (Central), Medical Students, Junior Doctors and General Surgical Registrars have reduced exposure to the speciality and the management of common cases in neighbouring hospitals (East and West). Subsequently, we developed a regional virtual teaching programme to help bridge gaps in knowledge and to instil confidence when providing a service. Method We developed a 4-part didactic webinar educational programme which covered parts of the medical undergraduate and MRCS curricula pertaining to Vascular Surgery. Under/Postgraduate educational leads from Central, East and West were contacted to promote our programme. Webinars were delivered on ZOOM video conferencing once weekly throughout December 2020. Feedback forms were collected on Google Forms™ and used 5-point Linkert scales to grade responses and analysis of data was carried out on Microsoft Excel®. Results 186 feedback forms were collected and respondents reported significant improvements in knowledge in each of the subjects covered: [1] Abdominal Aortic Aneurysms - (2.59±1.07/5 to 4.23±0.65/5, p = <0.0001, n = 60), [2] Acute Limb Ischaemia – (2.55±1.11/5 to 4.21±0.72/5, p = <0.0001, n = 42); [3] Chronic Limb Ischaemia (2.57±1.03/5 to 4.23±0.77/5, p = <0.0001, n = 35); [4] Vascular Emergencies (2.94±1.28/5 to 4.37±0.63/5, p = <0.0001, n = 49). Overall topic interest, presentational skills and clinical usefulness was also rated highly. Conclusions Through this virtually delivered regional teaching programme, we successfully enhanced Vascular Surgery knowledge and addressed the educational needs of Medical Students and Junior Doctors across North Wales.

Bituminous coals on emergent surfaces in an Asbian, lower Carboniferous (Mississippian) limestone succession on the North Wales carbonate platform, UK, and implications for palaeoclimate

Emergent surfaces in the Mississippian (Asbian to Brigantian) carbonate platform succession of North Wales record periods of plant colonisation and peat formation that led ultimately to the local development of coals. Examination of bituminous coals on three emergent surfaces within Cefn Mawr Quarry reveals information on palaeoclimate that is not available from study of the limestones alone. Three coal seams in the Asbian Loggerheads Limestone Formation were identified and the lowest one studied in detail. Vitrinite reflectance data from alternating bands of vitrite and duroclarite microlithotypes, the distribution of pyrite within them, and the sharp contacts between them, suggest that there were abrupt changes in marine influence during the development of the peats that formed the coals. It is inferred that local palaeoclimate alternated between periods of high and low rainfall, the amount of rainfall influencing the extent to which seawater encroached into the peats, with higher rainfall suppressing the ingress of saline waters into groundwater. On the basis of modern peat growth rates, the timescale of the alternation indicated by each duroclarite-vitrite couplet is suggestive of an annual cycle, such as would arise in a monsoonal climate. The low proportion of ash in the three coals, the preservation of internal lamination, the low diversity of spore species in the lowest coal compared with the over- and underlying mudrock, and the presence of rhizoconcretions in palaeokarstic limestone beneath the lowest and highest coals, demonstrate that the peat swamps were isolated from the hinterland and autochthonous. This study demonstrates that a wider application of palynology and coal petrology is an important contribution to the study of marine carbonate successions of any age where terrestrial organic matter, formed during emergence, has been preserved.

Consumed Landscapes: Coal, Air and Circulation in the Writings of Catherine Hutton

This essay examines a particular nexus of ideas about health and circulation in relation to the practice and the literature of travel and tourism in Romantic-period Britain. Wales, like other ‘picturesque’ destinations, is often envisaged in these writings, and in fiction, as a space of non-metropolitan purity, of clean air, and of health. Yet this is precisely the period of industrial expansion in both south and north Wales, and coal-mines, copper-works, iron foundries and smelting furnaces also figured on many tourist itineraries. Taking as its entry point the novels of Birmingham-based writer Catherine Hutton – particularly The Welsh Mountaineer (1817), which was informed by the author's own experience of travel in north Wales in the late 1790s – the essay sets the familiar trope of travel for a ‘change of air’ against the literal changes to air quality which resulted from Britain's rapid industrialisation in the decades around 1800, revealing some inventive and complex adaptations of contemporary ideas about the effects of ‘pure’ and ‘polluted’ air on human health.

Who Was John Sampson Really Protecting?

Begun in 1888, the Gypsy Lore Society (GLS) set out to describe and preserve Welsh Kale Romani customs, culture and language. Leaders in this effort were John Sampson, Francis Hindes Groome and Dora Yates, among others who took on the role of ethnographers, anthropologists and linguists. This paper raises the question, “Who Was John Sampson Really Protecting?” It is answered through an extensive examination of documented sources: birth records, census records, newspaper articles, Gypsy Lore Society Journals, academics on racism, and modern-day ethnography and anthropological practices. As well as family history; the archived memory of a Wood family member. It is premised on these facts – that John Sampson’s ethics, methods and emotional investment ignores the context and inhumane impact of his study, namely the everyday lives and voices of his subject matter. His goal was heavily influenced by the works of Charles Darwin and intellectualbaggage of the history of the world seen through British eyes; simply as a straight line from cultures to possess the deep roots of civilization itself. The purer and more hidden the better. The method used by John Sampson was to capture as much of the Welsh Kale culture and language by embedding himself in one family – the Wood family who he proclaimed spoke the “pure” Romanus language of the Abram Wood tribe of North Wales. His published work on this is The Dialect of the Gypsies of Wales: Being the Older Form of British Romani Preserved in the Speech of the Clan of Abram Wood” (1926). Against this intellectual stronghold fortressed inside a racially superior monolith, the story of Edward Wood, John Roberts and their extended family is told. Ethically however, his project also raises serious questions about the dichotomy of singling out the Wood family from others who also spoke Welsh Kale Romanus but were excluded from John Sampson’s studies. He and the GLS recast the Wood family in romantic Victorian terms to use as props with which to stage their inventions in widely published articles to a gullible audience. In this paper, the moral position taken is one of noncompliance with the Romanized recasting and politicizing of the “Pure” Gypsy that local authorities used as policy to rationalize the separation of families and force them into housing right up to the 1970s. What is called today, “Scientific Racism”. Concluding with the ways we are dealing with the intergenerational trauma and the collateral damage done to these Welsh Kale families. Asserting, our own voices and legacy have earned us a rightful place in the wider collective as we commit to standing together in our ethnicity, diversity, and authenticity with all Roma.
