very often containing garnet. Incomparably the most common 

 are coarse biotite gneisses with pronounced schistosity; in these 

 layers of hornblende schists were frequent, so, for instance, 

 on Danmark 1., and, according to Hartz, inside Gaase Fjord, 

 there together with chlorite and talc schists, and traversed by 

 dikes of a peculiar amphiboline peridotite ^). Not rarely the 

 gneisses are fine-grained, at times the mica retires, and now 

 and then we find garnet- bearing, compact, finely banded forms, 

 the appearance of which strongly reminds one of the true Saxou 

 granulites. Nor are rocks similar to mica-schists wanting. From 

 Danmark I. a small mass of archæan limestone is reported. 

 It is especially remarkable that granitic rocks seem to be very 

 scarce. From Bregne Point on Milne Land comes a specimen 

 which may be a coarse biotite granite, while a fine specimen 

 of coarse red granite (according to Hartz, a "dike-formation 

 in gneiss") was met with in Hjörnedalen inside the fjord. More- 

 over, pegmatitic veins were found in some places, but otherwise 

 such kinds of rock seem to be lacking, in contrast to the state 

 of things in the coast-belt, where granites together with red 

 gneisses and hornblende schists play the leading part. 



In Nordostbugten (North-east Bay) I myself collected a 

 series of blocks, among which were several grey gneiss-granites, 

 but along with these also limestone and a more recent-looking 

 syenite; it is conceivable that the latter was brought in by 

 drift-ice from outside the coast-belt, and this may possibly be 

 the case with the former as well. 



under the microscope, too, these rocks show the same 

 uniformity; they are destitute of any characteristics unusual in 

 gneisses. They often contain microcline and garnet, the struc- 

 ture is the typical one, with pronounced lobate limitation in 

 the grains, which, perhaps by reason of secondary growth, 

 often poikilitically enclose lesser individuals. Relic siructures
