 to what is else the case with the neptunite from Narsarsuk. 



The surfaces are rather well developed and bright; in the 

 large crystals, however, they are somewhat curved. 



Accompanying minerals are most frequently quartz, mi- 

 crocline, and aegirine; in a single case the mentioned minerals 

 are together with elpidite imbedded in a large individual 

 of calcite.
