In Scotland, volcanic rocks are often abundantly present--but the areas of Permian strata in that country are small and detached. A name proposed by Sir Roderick Murchison: from Perm, a Russian government in which strata of this age are largely developed. Upper group: consists principally of, first, marl slate or shale, which contains occasional thin compact magnesian limestones; and, second, magnesian limestone--a very variable series of yellow and brown--fine-grained, compact, crystalline, brecciated, and earthy limestones. Some beds resemble piles of cannon-balls, or heaps of turnips, or bunches of grapes--others are quite oolitic. The fossils of this group are abundant, and all (with the exception of a few drifted land-plants) of marine species. The series is well seen upon the coast between the Wear and the Tees. In the north-west of England the magnesian limestones are very sparingly represented, but at St Bees Head there occurs a set of red sandstones and marls with gypsum, which are the highest beds of the formation, and appear not to be represented in any other district in Britain. In Germany the Permian is composed of two members--the Zechstein and Kupfer-Schiefer, corresponding to the upper group; and the Rothliegendes, or Roth-todt-liegendes, representing the lower group of Britain. 49. The fossils of the Permian strata approximate generally to those of Carboniferous times--their fades is decidedly Palaeozoic. Most of the plants belong to genera which are abundant in the Carboniferous strata, and some species are said to be common to both formations. Some eighteen or twenty species of plants are known in the English Permian rocks; among these are lepidodendra and calamites, but sigillaria and. . .
