[APP. N°. I. 
the inferences as to the composition of the country, drawn 
from the shape and grouping of the mountains, and the 
forms of the cliffs as seen in the distance. 
II, Specimens from Cape Lister, and along tiie Coast 
to Cape Sivainson. 
1. Black mica. 
2. Mica-slate, inclining to gneiss, and in some specimens 
mixed with hornblende. 
53. Quartz, common variety. 
4. Common- calcedony. 
5. Red gneiss. 
6. Grey gneiss, like that of Huntly in Aberdeenshire, and 
Freybcrg in Saxony. 
7. Coarse granular hornblcndic gneiss. 
8. Gneiss passing into granite. 
9. Syenite, in which the felspar is deep flesh-red, and con¬ 
taining disseminated epidote. 
10. Hornblende-slate, with intermixed quartz and felspar. 
11. Coarse red granular syenite of Werner. 
12. Red granite, in which the mica is disposed in six- 
sided tables and prisms. 
13. Secondary greenstone, probably from a vein or overly¬ 
ing mass'; the calced'onyevidently from the greenstone. 
Remarks .— The rocks of this set of specimens, with ex¬ 
ception of the greenstone, belong to the primitive class, 
and are varieties of those original rocks that probably form 
the most extensive tracts in Greenland. The red Granite 
may have belonged to some central imbedded mass of that 
rock, or it may have been broken from a bed in the gneiss, 
or from a vein traversing the strata of that rock ; but 
whatever its situation was, it is evidently a true granite.
