as Old Red Sandstone аз a matter of course’. Pmerr (1843), 
on the other hand, referring to the abundance of porphyry-dykes 
in the sandstone, compares it with the Permian ‘‘Rotliegendes” 
in Germany”, while онкзтвор is of the opinion that a pre-Cam- 
brian age is more probable®. In the second volume of ‘‘Ant- 
litz der Erde”, Suess points out the analogy between the Igaliko 
Sandstone and the Liefde Bay group of Spitzbergen; the latter 
which according to Naruorsr's investigations contains Cephalaspis, 
Scaphaspis, and plant-fossils agreeing with those of the Old 
Red Sandstone, is the oldest sedimentary deposit of Spitzbergen 
which is uninfluenced by tangential stresses, and in South Greenland 
the Igaliko Sandstone occupies a similar position; it is probable, 
therefore, that the Igaliko Sandstone is of Devonian age‘. 
During recent years a number of scientific expeditions have 
explored the eastern coast of Greenland and have thus afforded 
the means of adducing for comparison the sedimentary succes- 
sion of this country. The southernmost occurence of sedimen- 
tary rocks in East Greenland is in the district north of Scoresby 
Sound from which the expeditions of Вурев (1891—1892), Nar- 
Horst (1899), Amprup and Harrz (1900) have provided informa- 
tion of great interest in regard to the question of the geological 
age of the Igaliko Sandstone. 
Thus, in the inner branches of King Oscar’s Fjord and of 
Emperor Frantz Joseph’s Fjord (72°—74° N. lat.) Млтновзт found 
a series of Silurian (or Cambro-Silurian) deposits resting on a 
basement complex of gneisses and crystalline schists®. This 
Silurian series consists of folded limestones, dolomites, slates,
