To quickly assess the difficulty of the text, read a short excerpt:
This locality is as it were the ultima thuU of the Marl-slate and its fossils — just as the adjoining quarry at Whitley is that of the Magnesian Limestone and its fossils. These outliers form the most northerly fossiliferous rocks of the Permian period in Britain, assuming the sandstones and breccias north of the Sol- way to be without fossils. It would be useless speculating as to how much further north the strata to which they belong origi- nally extended, though the existing evidence favours... the idea that they ranged in that direction far beyond their present limits. Certainly there is none of thfit obscurity about the manner in which the Magnesian Limestone terminates to the north as there b in respect to the south. No portions of the Series, where last seen in Durham and Northumberland, show the least traces of becoming sandy and argillaceous, like the Magnesian Limestone of Derbyshire and Nottinghamshire. Nor do the fossils of these two localities indicate any approach to a change either in the distribution of species, or in their individual peculiarities, simi- lar to that observed in the south.
