Abstract
I am enabled, by permission of Prof. A. C. Ramsay, Director-General of the Geological Survey, to lay before you the general results of the Survey examination of the Permian, Triassic, and Liassic rocks in the country bordering the Solway Firth; but I do not propose to discuss here the glacial drift and other superficial beds by which the surface of the ground is almost entirely covered, and which are the main hindrance to an understanding of the rocks which form my subject this evening. Papers on the Permian and Triassic rocks of the North-west of England have been read before this Society by Prof. Sedgwick, by Sir Roderick Murchison and Prof. Harkness, and by Mr. E. W. Binney. But as few districts promise less, except as regards drift and peat-mosses, than that immediately around the Solway, it has hitherto been dealt with, as a whole, in a brief and cursory fashion. In addition, a knowledge of certain borings, the results of which are by no means generally known, is absolutely necessary to a correct view of the structure of the Carlisle basin (see Map, Pl. XI.). The lowest bed with which we are here concerned is the great brick-red Upper Permian sandstone, so well shown at St.-Bees Head, and named, therefore, the St.-Bees Sandstone. Between St.-Bees Head and Maryport the coast consists of the underlying Coal-measures, the St.-Bees Sandstone having been swept away by marine denudation. But at Maryport it again becomes visible, its most northerly appearance being below Swarthy
