Abstract
IN his presidential address to Section C (Geology), Prof. W. J. Pugh points out that the history of the Lower Palæozoic is the evolution of a geosyncline with its marginal shelf-seas, which extended from south-west to north-east across the western part of Great Britan. This prolonged period of marine sedimentation was accompanied by extrusive and intrusive igneous activity and was closed by the Caledonian mountain-building movements.
