size, those mentioned above. In a few cases it is seen in 

 smaller crystals, 1— 2°^™ in length, which, in addition to 

 ^•{lOTl}, almost always exhibit well-developed faces of 

 a {1120} and c>i(022l}. One fragment contains very small 

 crystals (about 1/2'"°^) together with stilbite; here r{l0Tl}, 

 s {0221} and e(0lT2} are almost equally developed. 

 Danmarks Ö in Scoresby Sund. A few loose blocks 

 of basalt were found here containing small chabazite crystals 

 unaccompanied by other zeolites, but sometimes associated with 

 calcite crystals. The form is almost exclusively that of the fun- 

 damental rhombohedron. The crystals are semitransparent and 

 greyish. 



Floating ice near Iluilek in South-Greenland. 

 On the drift-ice a fragment of a grey fine-grained basalt was 

 found. This has numerous cavities , some of which contain 

 chabazite crystals, others levynite, while others are lined with 

 a quite thin layer of a soft, sky-blue mineral: celadonite or 

 lithomarge. The basalt is not quite like any variety found in 

 East-Greenland and the minerals also differ from those of 

 known localities. The chabazite occurs in rather small crystals 

 of 2 — o"""^ in length. The only form is that of the fundamental 

 rhombohedron: r(l0Tl}. Twin formations are very common, 

 especially about >-{lOÏl). The same crystal may be twinned 

 about different faces of the rhombohedron. The crystals are 

 colourless and semi-transparent. 



Levynite. 



Levynite has been found in a few localities in East-Green- 

 land, though not in large quantities. 



As however this mineral is, generally speaking, rarer than 

 the other zeolites, we must suppose that on the whole it is 

 more common in East-Greenland than elsewhere. 



Henry Glacier, the medial moraine. A brown fine-grained 

 basalt was found here with numerous cavities containing various
