lowest parts of the mountains, and in the plains *. This ne- 

 vertheless is subject to many exceptions. 



Transitio7i Rocks. — The transition rocks of Sweden are 

 distinguished by their extent in an horizontal direction com- 

 pared with their thickness, their position, and the nature of 

 the fossils they contain. The rocks composing them are the 

 following : graywacke, conglomerate, and quartzose sandstone ; 

 hornstone porphyry, and flinty slate; diorite both compact 

 and porphyritic ; a fine-grained and sometimes red-grayish 

 sandstone, nearly without organic remains; aluminous slate; 

 compact limestone, containing orthoceratites ; and clayslate, 

 containing fossils of the same genus, but smaller, named grap- 

 tolites. A thick bed of greenstone occurs on the elevated 

 summit of Mount Westgotha, above the four latter rocks ; it 

 is difficult to determine whether it belongs to the transition 

 epoch, or is of volcanic origin. 



The author afterwards describes with much care the dif- 

 ferent districts of Sweden in which transition rocks occur ; 

 viz. Dalecarlia, Jemtland, Nericia, Ostrogothia, Westrogothia, 

 KinnekuUe, the Hunneberg and Halleberg, Mount West- 

 gotha, the isle of Oeland, Scania, and the isle of Gottland. 



Secondary Rocks. — The formations belonging to the secon- 

 dary epoch are confined within the districts of Schonen and 

 Scania. They are divided into two portions : sandstone and 

 limestone. 1. Sandstone, containing beds of coal, bituminous 

 slate, and schistose clay, occurs along the Sund, for the length 

 of from three to four leagues, on the south of KuUaberg ; its 

 greatest breadth between the Sund and SUderas is more than 

 a league and a half. The large-grained sandstone in the en- 

 virons of Hoor, near the northern shore of lake Ringsjo, ap- 

 pears also to belong to the coal formation. 2. The limestones 

 are of different kinds : Muschelkalk forms thick beds near the 

 church of Ignaberga, at the foot of the Balsberg, near Chris- 

 tianstad, and in the environs of Carlshamn. 



The limestone mixed with sand (greensandf) is developed 

 in the countries of Svenstorp, Kopinge, Glamming, and In^ 

 gelstorp, in the districts of Ingelsta and Herresta, and to the 

 E. of Istad. Beds of chalk, with nodules of flint alternating 

 with a compact white limestone, are seen near Linhamn, on 

 the Sund, to the S. of Malmo. 



Basaltic Rocks. — Tliese occur in Scania, at Holmestrand, in 

 the southern part of Norway ; at Mount Anneklef, near Hoors ; 

 at the Gjelleberg, near the church of Rostanga. An amyg-
