140 P. SCHEI. 



jlllj always occurs and so does ßSi\, with one exception 

 only. As seen from Haidingers description of the Greenland mi- 

 neral this form is not sharply destinguished from }230{. On the 

 contrary, the two faces pass insensibly into each other and from 

 this reason the pyramidal crystals with jOOlj, jlllj and j231| 

 aquire, by a certain thickness, a length 2—3 times that, which 

 would be the proper one of a crystal with the form j231j regu- 

 larly developed. (Fig. 3.) 



The prism j230| is found clearly developed on one crystal 

 only; this specimen was found lying wholly surrounded by feld- 

 spar in the midst of the wedge and consequently shows crystal- 

 lographic boundaries at both ends and thereby displaying the 

 bipyramidal-tetragonal symmetry, jlllj and jl31j occurring at 

 both ends of the verticl axis as shown in the fig. 4. 



2. Uraninite from Evje, Sætersdalen. 



This mineral was recorded from Norway for the first time 

 by Scheerer, who found it at the Gamle Grube in the mountain 

 tract of Strømshei, NE of Sætersdalen. 



Later, it was found by Mr. Knutsen in Evje, Sætersdalen, 

 and here, the present writer happened to find it, in the summer 

 of 1903, at three different localities. 



At first it was found in the feldspar quarry at Landsværk. 

 Here it obviously occurs very sparingly; during a month's stay 

 some few specimens were got, in the southern end of the peg 

 matite mass, near its boundary against the country rock. How 

 ever, it has been found before, as it was known to the proprietor 

 of Evje Nickel Mine, colonel Henriksen, to occur at Landsværk 

 and very probably this is the place where, it was found by Mr 

 Knutsen. 



Next, it was found at Aaseland, and that place yielded more
