fibrous mesolite studded on the inner surface by numerous 

 short needle-shaped crystals. The mesolite was much disinte- 

 grated and оГ a brownish colour. 



Кар Brewster. The specimen found here was a block 

 with a single cavity, the walls of which were covered with 

 radiating groups (about 2 cm.) of snow-white mesolite. The 

 central part of the cavity is almost filled with calcite , into 

 which fine mesoHte needles project everywhere. When the 

 calcite is dissolved out with hydrochloric acid, the hair-like 

 radiating crystals are very distinctly seen. 



Scolecite. 



This mineral has only been found in a few localities in 

 East-Greenland and in rather small quantities. Well-developed 

 crystals are not found. 



.Mount Henry. The specimen is a loose block con- 

 sisting wholly of scolecite, without any surrounding rock and 

 unaccompanied by other zeolites. The scolecite is found in 

 crystals arranged in radiating groups; the length of the crystals 

 may reach 6 cm. and the breadth 1 — 2^^. The faces devel- 

 oped are w{ll0} and 6{010}; no terminal faces are developed. 

 The crystals, generally speaking, are somewhat decomposed, 

 opaque, white on the inside and brownish outside. The faces 

 are quite dull. 



Turner Ö. A few pieces of scolecite without any sur- 

 rounding rock, are accompanied by small masses of columnar 

 and crystallized thomsonite. The scolecite forms radiating mas- 

 ses to the size of 5 cm. More rarely, freely projecting crystals 

 are found bordered by w{ll0) and ^{oio} without terminal 

 faces. The colour is generally snow-white, sometimes reddish. 



Sabine Ö. A couple of small fragments have been ob- 

 tained from here , of about 3 cm. in diameter. They consist
