APPENDIX. 
No. I. 
LIST of SPECIMENS of the ROCKS brought 
from the Eastern Coast of Greenland, with Geo- 
gnostical Memoranda. By Professor Jameson. 
I. Specimens found on Icebergs near Cape Brewster. 
1. Transition clay-slate. 
2. Slaty talcose granite. 
3. Granular felspar. 
4. Hornblendic mica-slate. 
5. Gneiss. 
6. Basaltic greenstone. 
Remarks .—The specimens above enumerated, inde¬ 
pendent of those collected on the coast, would have afford¬ 
ed proofs of the existence in this country of Primitive, Tran¬ 
sition, and Secondary rocks; the talcose granite, gneiss, 
hornblendic mica-slate, and granular felspar, being primi¬ 
tive ; the clay-slate, transition; and the greenstone, second¬ 
ary. So that thus a few stray specimens on an iceberg, 
would have enabled the mineralogist, who had no oppor¬ 
tunity of landing, to correct and confirm, to a certain extent.
