believe that the conglomerate and the schists on Liverpool 

 Land do not belong to the same period, situated as they are 

 on the level immediately below the Ryders Dale rock men- 

 tioned above and not far from it. 



The crushed rocks that occur on several places in the same 

 district, indicate that the boundary between the Archaean rock 

 and the more recent fossiliferous formations on the west side 

 of Liverpool Land is marked by a zone of dislocation. 



4. The sedimentary rocks of C. Fletcher. As we have already 

 seen, the beds cropping out at C. Brown, in the most north- 

 easterly part of Fleming Inlet, apparently belong to a somewhat 

 older series than the Triassic inside the fjord. Still further 

 along the coast-band, about 20 km. SSE. from C. Brown, the 

 expedition made another landing at Cape Fletcher, the SE. cape 

 of Canning Land at the entrance of Carlsberg Fjord (cfr. fig. p. 197). 

 As the district between these two capes is still unknown it is not 

 possible to express any opinion about the series of rocks at that 

 place. The series at Cape Fletcher, however, it could easily 

 be shown, must be older that those at С Brown, traversed as 

 they are by several dikes or bosses of the same porphyry rocks 

 that are represented amongst the pebbles of the conglomerate 

 at the foot of С Brown. 



During our landing 1 devoted myself chiefly to studying 

 and collecting these porphyry rocks, which shall be described 

 in a later chapter. But 1 also got some conception of the 

 sedimentary formation, though I cannot report on the strati- 

 graphic conditions. The types of rock alternate very considerably; 

 there are firstly hard, undoubtedly dolomitic limestones of a 

 grey or black colour, and often of a very fine oolithic structure. 

 The limestone alternates at times in thin bands with chert or 

 silicious schists, and often contain small, rounded lumps of 

 flint. Characteristic is a coarse, light-grey dolomite breccia. 

 Furthermore, we came across, as a more irregular mass, a 

 black, hard chert- or flint-like rock which, however, under the
