cannot be more than 250 feet of rock.In both these burns there is an almost continuous series of sections,and there are no signs of faults. Both about Brampton on the onehand and west of the Esk on the other the thickness of the St.-BeesSandstone must be very much greater. Two outliers of KirklintonSandstone exist—one at Canobie, opposite the church, resting onCarboniferous rock; the other on the Cambeck near Walton, restingon St.-Bees Sandstone. Thus the band of St. Bees-like rock seen inthe Kirklinton Sandstone on the Line goes for nothing when thewhole of the evidence is considered, important as it would be did itstand alone. In consequence of this decided unconformity to thebeds below, I have, classed the Kirklinton Sandstone as Bunter. It is evident that the Stanwix Marls, in their turn, repose uncon-formably on the Kirklinton sandstone ; for while at Cliff Bridge andWestlinton they rest upon the lower red beds, at Stainton and x2 296 T.

And there seems to me to be little doubt that the Lias, in its turn,rests unconformably on formations all of which are unconformableto each other—the Gypseous Shales, the Kirklinton Sandstone, andthe Stanwix Marls. But as in this case it is barely possible, thoughnot, I think, probable, that the Stanwix Marls may overlap the twolower formations and underlie the Lias throughout its area, thepossibility seems worth mentioning. In this paper such facts only have been brought forward asseemed necessary to establish the true relations of the various for-mations to each other, fuller details being reserved for a forthcomingmemoir. Note on the Lias. April 25, 1881. Since writing my paper, my attention was called by my friendMr. H. B. Woodward to a passage in a paper by Rev. J. E. Cross On the Geology of North-west Li
