natrolite. mesolite, scolezite , thomsonite, calcedony, quartz, 

 calcite and aragonite were found to occur. 



On M an by Peninsula no minerals were collected and, 

 on Stewart Ö, only small quantities of calcedony. 



The district round Кар Brewster is fairly rich in 

 minerals and various zeolites were found but none in large 

 quantities ; calcedony and quartz were present. Jameson quoted 

 from this locality: calcedony, cacholong, grey and white ame- 

 thyst and a fibrous zeolite. 



The basalt along Scoresby Sund contains large quan- 

 tities of chabazite and differs in that respect from that of the 

 district mentioned above; thomsonite and levynite are widely 

 distributed here, but stilbite, heulandite, apophyllite and calcite 

 occur only in insignificant quantities. 



Very few zeolites have been found in the regions further 

 north. The expedition brought back very small quantities of 

 scolezite and stilbite from Sabine Ö. Lenz mentions other zeol- 

 ites, chiefly chabazite as being conspicuous in the rock of 

 Pendulum Ö and minerals such as quartz, calcedony, calcite 

 and aragonite, which were found in various locahties, will be 

 treated of later. 



No zeolites have been seen in Jan Mayen up to the 

 present time; the expedition brought back, however, small 

 quantities of calcite and aragonite. 



Owing to our very slight knowledge of the East-Greenland 

 minerals, it is difficult to draw a comparison between them 

 and those of the other basalt-regions situated nearest to them, 

 namely West-Greenland and Iceland. 



Both of these regions have been carefully examined and 

 considerable quantities of difi'erent minerals have been obtained 

 from them, also a very much greater number of specimens 

 of tlie individual minerals. The basalt of the northern regions 

 and that of Scoresby Sund seem to agree most closely as 

 regards the minerals with that of West-Greenland. This agree-
