of scolecite, the crystals of which are arranged parallel to one 

 another. The surface of the fragments is worn and disinte- 

 grated. 



Apophyllite. 



Apophyllite is very rare in East-Greenland as it has only 

 been found on three fragments from two different localities. It 

 varies very much in its development in the different places ; as 

 a rule the crystals are of a fair size. 



Кар Brewster. From here we have a single amygda- 

 loid, without surrounding rock. The 

 apophyllite fills the greater part of 

 the cavity and is not accompanied 

 by other minerals. The size of the 

 crystals varies from 1 to \o^^. The 

 crystal form is almost cubical (fig. 4), 

 with c(OOl) and a{lOO} most pro-

faces of p [111]. The faces are 



rather badly developed and dull. The crystals are brownish- 

 white and semi-transparent. 



Sydbræ, in Scoresby Sund. 



1) In one of the basalts with cavities containing thomsonite 

 and stilbite, which are so frequent in these parts, a few 

 crystals of apophyUite were found. These were developed 

 on the thomsonite crystals, some singly and some in groups. 

 The size of the crystals is about 15™™. The form is that 

 of acute pyramids, with p{lll} and a{lOO} predominant. 

 Very small faces of c{00l) and з/(301} are also developed. 

 The faces are curved and very rough. The crystals are 

 semi-transparent and of a greyish colour. 



2) A fragment of basalt was found, having no connection with 

 the specimens mentioned above and with regard to which 

 it is expressly staled that it was found in situ. Within it 

 are columnar masses of apophyllite without crystal-faces.
