Geology of Scandinavia. 305 



deposits which may be compared, in their nature, with the 

 Fahluns of Touraine, and the Suffolk Crag^ but which are 

 probably more modern. 



Every one is acquainted with the curious observations made 

 in 1807 by M. de Buch, and verified since that time by M. 

 Brongniart and Mr Lyell, on the deposit of marine shells of 

 species now living, situated at Uddevalla in Sweden, near the 

 frontiers of Norway, 70 metres (about 230 feet) above the sea.* 



Deposits of the same kind have been observed in the envi- 

 rons of Stockholm, as also at Orust, and on the banks of the 

 lake Rogvarpen. 



The environs of Christiania also exhibit examples of this kind. 

 Professor Keilhau has observed them there, even 600 feet above 

 the sea. M. Eugene Robert, in his journey through Norway 

 and Sweden last year, has likewise stated different facts of the 

 same kind. He remarked, for instance, between Drammen and 

 Christiania, on the side of the road at Raunsborg, a black fetid 

 limestone, with Terebratulae, full of shells of the Saxicava 

 riigosa^ which have perforated it at an epoch when the sea 

 reached this point, now elevated 500 feet above its level. 



Facts of this kind are valuable, because they are clear and 

 undeniable. We may expect to find examples of them through- 

 out the whole extent of the coasts of Norway. 



Marine shells of species now living, have been collected in 

 places far up the country, near Drontheim. According to M. 

 de Buch and M. Strom, deposits of this nature exist at an ele- 

 vation of more than 400 feet above the sea in the northern part 

 of Norway. According to M. de Buch, beds of shells are ob- 

 servable on the isle of Luroe, even within the Polar Circle, and 

 at Tromsoe, about the sixty-ninth degree of latitude. 



They also make their appearance again at Spitzbergen. Ac- 

 cording to Professor Keilhau, there is found in the Stans- 

 Foreland (one of the large islands which, taken together, form 

 Spitzbergen), at the distance of nine and a half miles from the 

 sea, and 100 feet above its level, a bed of alluvial clay con- 

 taining bivalves, and analogous to those on the coasts of Norway. 



• Linna5us, in his Travels through West Gothland, gives an interesting 

 account of the Uddevalla formation, and a plate, with figures of several of 

 the more important fossil shells.— jEWtt.
