character, similarity of position, and universality of distri¬ 
bution of the primitive rocks, in all parts of the world. 
Judging from what is known of the imbedded minerals on 
the west coast of East Greenland, and reflecting on the 
agreement of the rocks, both on the east and west sides of 
the country, we may infer, that if Captain Scoresby had 
had leisure for minute investigation, his scientific zeal 
would have been rewarded by the discovery of the hitherto 
rare cryolite, the sodalite and allanitc, with magnificent 
tourmalines and garnets,—interesting varieties of zircon,—- 
splendid specimens of hyperstene, the remarkable dichroit, 
and with all the species .of the felspar genus. There 
does not appear any reason why the ores of iron, lead, tin, 
and copper, of the West coast, should not occur in the same 
rocks upon the East; and the fine displays of apatite, 
calcareous-spar, fluor-spar, and of other simple minerals, 
on the West coast, which have been the source of so 
much instruction and delightful contemplation to the scien¬ 
tific inquirer, may, in some future voyage, present them¬ 
selves, in the newly discovered countries, to the eye and 
intelligence of the naturalist. 
2. Transition Rocks. 
The specimens of Transition rocks, although few in num¬ 
ber, are highly interesting, as proving the existence of 
that class in Greenland, and thus adding a new feature to 
its geognosy, for Gicsecke does not enumerate any of the 
slates he met with, as members of the transition series. 
This fact is also a further proof of the wide distribution of 
these rocks; and shews, in opposition to certain speculative 
views, that they arc not confined to a few narrow corners 
of the globe, but, like gneiss, mica-slate, &c. may be consi-
