LA white, hard sandstone, mostly devoid of organic remains. In a neighhouring 



island, however, are found imbedded in the sandstone impressions of Calamites, etc. 



and the sandstone therefore belongs to the same division as the Coal-bearing stratum 



on Bear Island, la, an inconsiderable layer of conglomerate. 



_2._ CyathophyUum Limestone. — A hard, grey, impiu-e limestone or dolomite con- 

 taining corals {GyatliophyUum), a Euomphalus, and portions of bodies and stems 

 of Crinoids. 



3. Spirifer Limestone, loose, grey, consisting almost exclusively of remains of Bra- 

 chiopods., 



4. A vein of diabase of great extent. 



5. Flint, rich in impressions and remains of Brachiopods, especially of Productus. 

 Similar, though less extensive flint beds, but without fossils, lie between the Cyatho- 

 phyUum Limestone (etage 2), but crop out first east of these limestone strata in such 

 abundance that they form the principal mass of the mountain. It is possible in this 

 mighty succession of strata to. distinguish two divisions. 



5a. A grey (but becoming yellowish-brown through weathering) , very close and 

 compact sandstone containing lime, which, when freshly broken, has a homogeneous 

 appearance, but when exposed for a considerable time to the action of the atmosphere, 

 has a rough and irregular surface. 



5h. A black flint, weathering to a limited extent when exposed to the air. These 

 strata are quite identical in respect of the organic remains they contain. The former 

 take up nearly the whole of Axel's Islands ; the latter a small ridge on the east side 

 of the island. On the southern island this flint stratum is covered by a pretty loose 

 marl-schist with fossils of various kinds. 



6. Sandstone with traces of vegetable impressions, probably belonging to the same 

 period of time as the stratum in Eobert's Valley (IV., C.) 



7. Frithiofs Glacier. — On the low land, which is now taken up by the glacier, were 

 observed in 1858 both black schists and a grey sandstone, which in all probability 

 also belonged to the same period of time as the stratum in Eobert's Valley, and in 

 the grave-mound now covered by ice, layers of a black schist rich in pyrites, which 

 probably belongs to the Jurassic formation.

sea, by von Drasche. 

 1. Grey limestone, containing silica, with a few fossils {Spirifer and Productus). 

 2. Grey sandstone, yellow after weathering, witli an immense number of fossils 

 (Bryozoa, Corals, Spirifer, Productus. etc.). 3. Flints, containing no fossils. 4. 

 Layer of diabase, with pretty large felspar crystals.
