Geology at the British Association

Abstract

THE address of the President, Prof. Grenville A. J. Cole, was a brilliant and stimulating commencement to the proceedings of this section. Following it came an interesting address by Dr. George Hickling on the geology of Manchester and district, in which he pointed out the excellent position of Manchester, both geographically and geologically, situated at the junction of the red beds and the coal measures, with a great variety of opportunities for field-work in the neighbouring Pennine Chain. Prof. E. J. Garwood followed with a paper on the discovery of Solenopora and Sphærocodium in the Silurian rocks of Britain. Up to the delivery of his presidential address at Birmingham these organisms had not been found in Silurian rocks, but careful search has now proved that Solenopora occurs both in the Wenlock and Woolhope limestones. In areas on the borders of Herefordshire and Radnorshire had been found crystalline limestones, upwards of 80 ft. thick, containing remarkable developments of these and similar algal growths, amongst which were the remains of Girvanella and Sphærocodium, the latter genus being now recorded for the first time from rocks in Britain.
