brown elliptic grains, which is probably titanile. Other varieties 

 contain biotite as well as hornblende. Apatite and zircon occur 

 more particularly as interpositions in biotite. On the other hand, 

 compact grains of ore are rarely found in these forms and a 

 distinct succession of crystallization between the minerals can 

 nowhere be traced. 



Finally, a rather peculiar variety may be mentioned which 

 occurs in a single piece and looks as if it had been found 

 detached, though it evidently had not been carried very far. It 

 consists of idiomorphic crystals of pale, yellowish-green horn- 

 blende with a perfect cleavage, lying in a mass that consists 

 chiefly of irregular grains of a still paler, green mineral, some- 

 times showing imperfect cleavages, sometimes much laminated, 

 and in the latter case showing a maximum extinction of about 

 18'^ towards the cleavages. The variety in question is doubtless 

 an actinolitic amphibole. There occur further irregular grains 

 both of colourless, fresh olivine and of a dark-green variety of 

 spinel, besides a small quantity of a peculiar pink pyroxene 

 which appears to have an oblique extinction, but otherwise 

 bears a strong resemblance to the rhombic pyroxene in the 

 rock from Angmagsalik. The rock, which may most properly 

 be called amphibolite-pikrite, perhaps forms an ultra -basic 

 link in the series described by Törnebohm and mentioned 

 above, and it also reminds one strongly of the rock met witli 

 by N. Hartz at Kobberpynt in the interior of Scoresby Sound, 

 and described by Bay and Us sin g M. 



From the district of Angmagsalik — i. e. from a 

 more southerly part of it than the above-mentioned (lat. OS'* 

 53' N. and long. 36° 5' W.) — there are two specimens, viz. 

 from the graphite rocks at the entrance of Ikerasak. The
