extended peninsula, and thus stretches further inland than the 

 northern, which latter I will now describe. 



The Northern Basalt Area is only known to me per- 

 sonally from our visit to Sabine I. and from a short landing 

 at C. Borlase Warren. Up to now our knowledge of this 

 area is chiefly indebted to the second German Polar Exp., 

 which wintered there; since that Nathorst has also published 

 a number of notes about it. I shall therefore confine myself to 

 a few observations. Sabine I. is characterized chiefly by the 

 huge and extensive stratifications of Tertiary sandstone found 

 in the basalt; nowhere in the basaltic area of E. Greenland 

 south of Hochstetters Land are they so extensive as here. 

 That the basalt is in part more recent than the Tertiary strata, 

 whose age is not exactly fixed, is proved by the dikes that 

 intersperse it, as also by the traces of contact metamorphism 

 I spoke of before. , Still, the basalt itself is the prevailing rock, 

 and round Germania Harbour it can be seen in its typical 

 development, formed of apparently horizontal sheets piled on 

 each other. Towards the interior of the island numerous dikes 

 appear, and in Hasenberg, built up for a good part of schists and 

 sandstone, we find also intervening layers of tufaceous rocks and 

 volcanic scoriae. Microscopically viewed, the forms I examined 

 are only noteworthy in their being considerably better preserved 

 and more thoroughly crystalline than the sheeted rocks in the 

 southern area, but I do not know whether this can be said of 

 such forms as, for instance, those around Germania Harbour, 

 which are of similar appearance as in the region mentioned. 



Also the rocks at C. Borlase Warren are coarsely crystalline, 

 doleritic, and slightly porphyritic. No fresh olivine is to be 

 found in them at the present moment. 



The Southern Basalt Area. This has never before 

 been the object of detailed observation. From the southern 

 side of Scoresby Sund to Kangerdlugsuak, where the coast 

 makes its bend to the south, and where its southern boundary
