The sandstone beds which skirt the eastern border of Wales, and stretch from a little south-west of the town of Oswestry to near the Point of Ayr, on the shores of the Irish Sea, a distance of upwards of 40 miles in a direct line, have for several years past been a source of perplexity to those who have investigated their peculiarities, and who have been interested in arriving at a determination of their true age and geological horizon.

AbstractA free-swimming thornback ray Raja clavata specimen demonstrating significant morphological abnormality is reported, captured by beam trawl in the Irish Sea off north Wales, UK. The anterior sections of both pectoral fins were separated from the head section for a length of approximately 140 mm extending from the rostrum tip to a point posterior of the spiracles, along with abnormal morphology of the gill slits. This phenomenon has been observed elsewhere but is the first documented example of this abnormality in the eastern Irish Sea, despite widespread targeting of the species across the region by commercial and recreational fishers. Possible causes and consequences of the observed abnormality are discussed.

The relationship between Britain and Ireland in the nineteenth century has been extensively studied, but the crucial significance of the London-Dublin communications link in this relationship has received less attention from historians. This article concentrates on the effect of establishing and maintaining this link on the strategically-placed town of Holyhead and, more specifically, how employment patterns in the town changed as Holyhead became the main mail packet port for the Irish Sea crossing.

Topographical and geophysical surveys carried out in August 2002 at three monuments in the Preseli Hills of Pembrokeshire are reported: Bedd Arthur, Gors Fawr and Meini Gwyr. Previously unrecorded features were revealed at all three sites, most spectacularly at Meini Gwyr which, from the evidence of geophysical survey, appears to be a multi-phase monument that includes a double pit-circle, hengi-form monument and embanked enclosure with an internal stone circle. Comparisons are made with plans prepared by Flinders Petrie in 1926, published here for the first time. A viewshed analysis of the surveyed sites and others of similar kind in the area allows an appreciation of landscape setting and intervisibility. It is suggested that the stone circles are sited in relation to upland stone sources. All the monuments considered here are compared with contemporary structures recorded elsewhere in the British Isles. It is concluded that while the stone circles and oval setting fit comfortably within a distribution pattern that extends across most of the British Isles, the later phases of Meini Gwyr at least belong to a more localized tradition of monument building focused on the Irish Sea region.

Sea Coast

Striking a radius of 40 miles from Southport, the line will be seen to intersect the sea-coast near the Silurian districts of Ulverstone in North Lancashire, and Colwyn Bay in North Wales. The succession in both cases is very similar, Denbighshire Grits and Flags of the one area corresponding in time to the Coniston Grits and Flags of the other; and just as the Silurians of the Lake District are overlaid by a fringe of Carboniferous Limestone, so the Silurians of Diganwy are overlaid by the Carboniferous Limestone of the Great and Little Ormes Head. Laid upon a floor of Silurian rocks, the Carboniferous Limestone may be regarded as extending continuously under the Irish Sea, and underlying the various Carboniferous and Triassic rocks now occupying Lancashire.

Set Up

The Isle of Man situate in the midst of the Irish Sea as an intermediate station between Ireland and Cumbria, North Wales and Galloway, has naturally played a considerable part in various phases of western British life in which coastwise maritime movements have had significance. The phase or phases of megalithic construction included, as is generally agreed, a considerable amount of maritime movement along the coasts of western Britain, and monuments of various types were set up. It may be stated at the outset that, since developments even as late as the introduction of Christianity show relations with megaliths, we are not justified, without special local evidence, in ascribing particular megaliths necessarily to an early period, though there is widespread agreement that some must have been in existence at about 2000 B.C., and even possibly earlier.

SummaryFor the determination of plutonium isotopes in environmental samples, chemical separation of plutonium together with a suitable sample preparation method for measurement is necessary. In this work, a combined method for the determination ofThe use of this approach gives the advantage of combining the strengths of both radiometric and mass spectrometric methods for plutonium determination after chemical separation from environmental samples.Results from the measurement of reference materials and from sediment samples from the Irish Sea are presented and the applied methods are compared with respect to their detection limits for the investigated nuclides.

Carboniferous Limestone

The Millstone Grit of the North Wales Border follows the eastern slope of the Carboniferous Limestone, from Crickheath and Sweeney, South of Oswestry, to the shores of the Irish Sea; it is also thrown up into the range of hills which the traveller by the Great Western Railway may see to the west of the line between Oswestry and Chester. This range serves as a natural boundary between this part of England and Wales, and forms a second line of natural fortification, strengthened on the English side by numerous outposts of low hills of clay, gravel, and sand, which give place, upon the Welsh side, to precipitous escarpments of Mountain Limestone, beyond which the change in the language, dress, and manners of the people is marked and sudden.

The Town

William Henry Bragg was bom at Westward near Wigton in Cumberland on 2 July 1862, and died at the Royal Institution on 10 March, 1942, in his 80th year. The obituary notice was written for the Royal Society by Professor Andrade, and we have always felt grateful to him for its sympathy and insight. It covers the main events of his career. We feel that our contribution now can best be some account of a more personal kind and the memories we have of him . Some fifteen years before he died he wrote for his family a biographical note which covers the period from his earliest memories up to his going to Australia in 1886. It is interesting to give some details of the family history, because his early upbringing explains so much of his later outlook on life. He came from a Cumberland family whose members were yeoman farmers or in the merchant navy; there were no academic traditions of any kind. His grandfather was drowned in 1839 when his ship was lost in the Irish Sea, and the widow and four children were left badly off. The eldest boy was only twelve at the time, but he seems to have taken on his shoulders the main burden of supporting and bringing up the young family. He was apprenticed to a chemist and later set up his own chemist and grocer’s shop in Market Harborough, where he did well and acquired a position of influence in the town. The second boy, Robert John Bragg, went to sea like his father, but coming into some money at the age of 25 he retired and bought a farm in Cumberland. He married the daughter of the vicar and our father was their eldest child.
