The distribution of Mesolithic sites in Wales is controlled to a great extent by the terrain, for physiographically, Wales is a highland block defined on three sides by the sea and for the greater part of the fourth side by a sharp break of slope. Geologically the Principality is composed almost entirely of Palaeozoic rocks, of which the 600-foot contour encloses more than three quarters of the total area. There are extensive regions above 1,500 feet and 2,000 feet and in the north the peaks of Snowdonia and Cader Idris rise to 3,560 feet and 2,929 feet respectively. Indeed North Wales consists of an inhospitable highland massif, skirted by a lowland plateau and cut deeply by river valleys, providing only limited areas for settlement. The hills and mountains of Snowdonia with their extension at lower altitudes into the Lleyn Peninsula, and the ranges of Moelwyn, Manod Mawr, Arenig Fach and Cader Idris, are discouraging obstacles to penetration, save for a short distance along the river valleys. To the east of these peaks are extensive tracts of upland plateau dissected by rivers, bounded on the west by the vale of the river Conway and cleft by the Vale of Clwyd. To the east of this valley lies the Clwydian Range and further again to the east these uplands descend with milder contours to the Cheshire and Shropshire plains.To the south the district merges into the uplands of Central Wales, which are continuous until they are replaced by the lowland belt of South Wales.

The total thickness of Millstone Grit in North Wales does not quite reach 300ft. This thickness is, I am aware, considerably below that given by several authors, who notice this formation incidentally; but I am prepared to say, from. actual and computed measurement, made on the spot, that the above figures are substantially correct. The Carboniferous system, from the base of the Mountain Limestone to that of the Coal Measures in North Wales, is but an epitome of the same beds in the North of England, the middle member, the grits and sandstones, being thin in proportion.

Nonpalpable Breast Lesions

Purpose: To compare the positive margin rates for women with nonpalpable breast tumors whom had wire localization compared to radioactive seed localization in a small community hospital.Introduction: Wire localized (WL) breast biopsies have been performed on patients with nonpalpable breast lesions for many years. Radioactive seed localization (RSL) offers advantages of patient comfort and scheduling convenience.There is an extensive literature from large centers regarding the RSL technique. Little is known whether physicians performing these procedures in smaller community hospitals can achieve comparable negative margin rates as those performed with wire localization.Methods: The thirty-six patients who underwent wire localized breast conserving surgery between September 18, 2013 and December 10, 2014, were compared to the 48 radioactive seed localization patients resected between February 12, 2014 and December 18, 2014. The primary objective was to determine if the introduction of the radioactive seed localization technique significantly changed the positive margin rate.Results: Two of 36 wire localized breast biopsied patients had positive margins, compared to 5 of 48 radioactive seed localization patients, a difference which is not statistically different. The specimen weight was larger for the patients treated with the RSL technique. There was a trend toward a higher positive margin rate with older patients.Conclusion: The positive margin rate was similar between the wire localized and radioactive seed localized patients, and comparable to those in the published literature.

Geological Work

1831 was a momentous year for Charles Darwin. He passed his BA examination on 22 January, stayed up in Cambridge for two further terms and returned to The Mount, his home in Shrewsbury, in mid-June. On 6 August he left Shrewsbury with Adam Sedgwick for a geological field trip to North Wales, and after his lone traverse over the Harlech Dome returned to The Mount on Monday 29 August to find letters from John Stevens Henslow and George Peacock inviting him to joint HMSBeagle. This geological field trip was crucial for his work on theBeagle. For example, when he began his first geological work of the voyage on Quail Island, he was by that time a competent geologist. Though others have studied the North Wales tour in some detail, there is also another earlier and much briefer episode to consider. Darwin appears to have geologized on his own at Llanymynech in July. The contrast between his first recorded attempts at Llanymynech in July 1831 and then elsewhere in North Wales in August 1831 is most instructive, as his development as a geologist can be followed in his field notes. Retracing his steps today, and comparing his measurements and observations with new ones, throws light on what he might have learnt at different points during that summer.

A Meeting of the North Wales Branch was held on June 18th at Llanberis. The discussion on examinations which had been begun at the previous meeting was reopened by Miss Prior, Girls’ County School, Bangor, who dealt in turn with the points raised in Prof. Bryan’s paper, from the point of view of the school-girl.
