4 hiilleflint-schist; 3 red granite, of more than medium-coarse 
grain; 2 grey granite—otherwise like the last-named variety; 1 
red hälleflint gneiss; 1 quartzite and 1 quartzite-sandstone ; whilst 
the remaining 4 specimens were put down as undeterminable. In 
the same moraine were also noticed limestone, red fine-grained 
sandstone, coarser sandstone, and sandstone conglomerate, sometimes 
with nodules of jasper and diabas. The sandstones and quartzites 
are very compact, as is generally the case with older sandstones, and 
bear a complete resemblance to many Swedish sandstones generally 
regarded as Cambrian. C. Pingel (in 1843) expressed his opinion 
that they are Permian; and K. J. V. Steenstrup (in 1877) takes 
Pingel’s side, and (in 1881) declares that there can be no reason for 
a different view as long as no petrifactions have been found in the 
sandstone. Yet there is no more reason to regard this rock as 
belonging to the Permian formation than to almost any other for- 
mation. Numerous dykes of diabase are met with in the southern 
portions of the district visited by Dr. Holst, all the way from Kipis- 
sako to Fredrikshaab. They are particularly abundant on the 
Tassiussak-fjord, and not less than twenty parallel dykes of green- 
stone were counted within a space of five hundred feet on the island 
Kikertarssuak, at the inlet to this fjord. East-southeast from 
Grönne Dal occurs a peculiar diabase breccia, and, close to it, dykes 
about a yard wide of a very fine-grained red rock, microscopically 
determined by Dr. A. E. Térnebohm! as a fine-grained syenite. 
B. The Interior Ice-covering.— Previous explorers of the inland 
ice have made the observation that moraines are found on the sur- 
face of the ice only near land, while the inner expanse of the ice- 
sheet is earthless, except the occurrence of the so-called kryokonite. 
What else it carries along is hidden more or less deeply in the mass 
of the ice. Knowing this, Dr. Holst thought it more fruitful to 
study the ice near its borders than to undertake time-wasting excur- 
sions into the interior. 
The inland ice expands ina continuous sheet from the mountains 
of the coast-lying land eastward beyond the horizon, only interrupted 
by the “nunataks” and the moraines. The former occur v 
sparingly, only the high peaks of the underlying mountains rising
