Plates L. to LVIII. PART I. Introduction. In a communication made to the British Association during its meeting at Bristol (1836), we first pointed out (by help of a section extending from the north coast of Devon to Dartmoor) the true geological position of the great culmiferous deposits, which occupy so large a portion of that county. In this paper our object is more extensive; for we not only attempt to describe the order of the successive formations north of Dartmoor, but also, as far as we…

IV.—Note on a New Fossiliferous Limestone in the Upper Culm Measures of West Devon
At the present time we are only fully acquainted with the geology and palæontology of one division of the great Carboniferous Series developed in Devon and the adjacent counties, the Lower Culm
The naming of the Permian System
The naming of the Permian by Roderick Murchison in 1841 is well known. This is partly because he ‘completed’ the stratigraphic column at the system level, but also because of the exotic aspects of
Adam Sedgwick, Roderick Murchison, the Magnesian Limestone (Zechstein) of northeastern England and the foundation of the Permian System
The acrimonious controversy between Sedgwick and Murchison with regard to the definition and boundaries of the Cambrian and Silurian systems in the mid-1800s is well known and documented. The claim
