Erikite. a new mineral. 



Xhe new mineral which is to be described here, has been 

 brought home by the geological expedition that travelled over 

 part of the district of Julianehaab during the summer of 1900 

 by the directions of Kommissionen for de geologiske 

 og geografiske Undersøgelser i Grønland. The mineral 

 was found by professor N. V. üssing, who charged me with 

 the work of collecting so much material as possible on the 

 finding place , and after my return home to make a thorough 

 examination of it. The examination, which has been made in 

 the Mineralogical Museum of the University in Copenhagen, 

 has shown that the erikite neither by its crystalline form nor 

 by its chemical properties is nearly related to any other 

 mineral. 



The mineral is named after Erik the Red who discovered 

 Greenland in 986, and after whom the Tunugdliarfik- 

 Fjord where the mineral is found, was formerly called the 

 Erik s fjord. 



The locality, hitherto the only one for the mineral, is the 

 little mountain N unar si uati ak at the Tunugdliarfik- 

 Fjord, which is also known as the finding place of fine cry- 

 stals of steenstrupite of type 1И), and of epistolite^) as also
