278 EMMERICH ON THE MORPHOLOGY, CLASSIFIUATION 
order of succession of the strata constituting the Swedish tran- 
sition formation ; and that (long before Murchison’s researches 
diffused a new and clearer light upon the whole system of the 
palzeozoic rocks) Wahlenberg (Acta Upsal. tom. viii.), and sub- 
sequently Dalman, described with great accuracy the distri- 
bution of the Trilobites in the rocks of Sweden. The pale- 
ozoic strata have in South and Central Sweden an uninter- 
rupted horizontal position (such as they are everywhere met 
with in the North of Europe), but exposed at numerous locali- 
ties by inundations, the younger strata having been washed to 
a considerable distance. The succession of strata may be best 
observed at those localities where a protective covering of basalt 
opposed a greater resistance to those destructive powers. All 
the isolated mountains, rearing their heads like castles from 
the level and hilly country of East and West Gothland, bear a 
basaltic crown on their summit, and the separate subdivisions of 
the transition formation appear like the steps of a gigantic lad- 
der. This scalariform appearance of the horizontally deposited 
strata seems to be nowhere more striking than at the Kinnekiille, 
a celebrated mountain on the east shore of the Wener Lake. 
The transition rock there consists of the following subdivisions 
in an ascending order :—at the lowest portion, which at other 
places rests on gneiss, we find,—1st, a siliceous sandstone, from 
which however no fossils are known. Thereupon follows, 2ndly, 
a slaty limestone, which is highly bituminous, and passes into 
brand and alum-slate with beds of stinkstein; 3rdly, a stratum 
of considerable depth, principally gray limestone, sometimes 
pure (marble), sometimes rather marly ; this is the richest bed of 
the Swedish Trilobites, Orthoceratites and other fossils. Upper- 
most and covered by trap, there finally occurs a second slaty 
formation, clay and marl slate of the Méseberg. This is the 
succession of the strata which Linnzus observed on the Kin- 
nekiille, at the Méseberg, Billingen and other localities. The 
subsequent researches of Wahlenberg, Hisinger, &c., have added 
no new member to it on the continent ; the entire Swedish con- 
tinent exhibits the same development from Dalecarlia to Schénen. 
It is only in the south, known above all by the numerous fossils 
of its alum-slate at Andrarum, that the rocks exhibit a deviation, 
the principal limestone acquiring a black colour from the inter- 
mixture of coal. 
We find the same system of division of the palzeozoic rocks on
