limited an area. In how far the same is true of the other 

 parts of the central mass inside the system of Kong Oscar and 

 Franz Joseph Fjords, is not easy to decide from the descriptions 

 that are to hand. We only find that the gneisses, here too, 

 are often garnet-bearing and that granites do not seem to play 

 any great part. 



It is from a fjord system situated far further north that 

 we presumably have a series of blocks that were collected by 

 me on the shore at Cape Borlase Warren. The rock in place 

 is coarse basalt. Amongst the boulders brought home are 

 coarse, almost pegmatitic rocks which most often have clearly 

 been subjected to pressure. Characteristic is a coarse, grey 

 hornblende-granite, also a coarse -red granite in contact with 

 a hghter, striped gneiss rock. Also more recent rocks, clay- 

 slates and sand -stones, occurred abundantly as blocks on 

 the shore. 



As regards the character of the archæan rock on the stretch 

 of coast S. of Scoresby Sund, 1 may refer to the description 

 of the rocks collected by Kruuse which I have published on 

 a previous occasion ^). 



С Liverpool Land. As far as we know, all this district, 

 too, is formed, in its bulk, of archæan rocks. Still, it is at 

 once evident that these are of quite another kind and ap- 

 pearance than those that occur within the known and neigh- 

 bouring parts of the central mass. This is true not only of 

 the west side and especially the tract nearest to the inmost 

 creek of Hurry Inlet, where the great variation may be bound 

 up with other factors, but also of other parts of the district. 

 So far, however, we have only material from a few places, i. e. 

 (apart from the west side) from a point on the southern ex- 

 tremity (Cape Tobin), and a spot on the east coast (Cape Greg)^). 

 I will first describe these places.
