variety makes an impression of being considerably alterated, 

 there is good reason to consider the schizolite variety as being 

 a partly alterated schizolite. 



New examinations of Steenstrupite, 



by 0. B. Boeggild. 



A considerable quantity of steenstrupite was collected 

 by G. Flink M on his voyage to Greenland in the summer 

 of 1897, which shows several new and interesting forms 

 not mentioned by Moberg^) in his paper on steenstrupite. 

 In the following pages the two above mentioned dissertations 

 are referred to as well as Lorenzen's^) first information 

 concerning the steenstrupite. 



The mineral occurs in the following localities , all situated 

 in the district of Julianehaab, South Greenland. On the 

 bottom of the Firth of Kangerdluarsuk and Naujakasik 

 to the East of the same the mineral was formerly found, 

 but now it has also been found at Tupersiatsiap, close to 

 the last mentioned place and in 3 localities lying on the 

 Northern side of the Firth of Tunugdliarfik, namely 

 TNunarsiuatiak, Agdlunguak and Tutop Agdlerkofia. 

 The mineral from the last mentioned locality is called by 

 Flink: «Brown rhombohedra» ; the steenstrupite found here, 

 and which represents the least altered form of the mineral, 

 occurs also in a type considerably different from the others.
