ment consists in the small size of the zeolites and the predo- 

 minance of the mineral chabazite. On the other hand , the 

 basalt south of Scoresby Sund resembles more the Iceland 

 basalt, the distance from Iceland being also inconsiderable. 

 The zeolites in this basalt, more especially the stilbite attain 

 a considerable size and, possibly, by a closer examination of 

 the country, we might discover that zeolites were present in 

 comparatively large quantities. 



A description of the places where the various minerals 

 were found will be given later, as also an account of the more 

 prominent characteristics of the minerals belonging to each 

 locality. For the position of the localities, reference should be 

 made to the maps accompanying the various accounts of the 

 expedition given in the Meddelelser om Grönland vol. 27. Maps 

 of the northern territory will be found in the account of the 

 German North Polar expedition and in Nathorst's treatise. 



Quartz. 



In the basalt-region of East-Greenland, quartz was found 

 in few localities and generally in small quantities. It was 

 either in very small crystals or amorphous. 



Кар Dalton. A fairly large quantity of quartz was ob- 

 tained from the walls of a cavity in the basalt on the slope of 

 Station-mountain. The walls of the cavity were thickly 

 studded with quartz-crystals to the length of 1 centimetre. 

 Form of crystals a short prism of the ordinary combination of 

 faces: w{loTo}, r{l0Tl}, «{OlTl}. The faces, especially the 

 rhombohedral faces are well developed and bright. The cry- 

 stals are semitranslucent and of a whitish colour. 



From the same locality was obtained a quartz fragment, 

 which filled a cavity. This is covered on the outside by im- 

 pressions of disintegrated calcite-crystals. 



Henry Glacier. The specinien is a fragment of the wall 

 of a fissure, consisting of calcedony covered with small quartz
