The Syenite, I suppose, formed a bed in the gneiss. Front 
the number of specimens of Gneiss, and other circumstance's, 
it appears that it was the predominating rock on this coast, 
and that the mica-slate, syenite, and homblende-slate, were 
subordinate to it. The red gneiss is that often met with 
near granite, and in districts abounding in red granite, 
while the grey gneiss occurs abundantly without granite, 
or in such districts as contain grey granite. 
The greenstone, from its association with calcedony, ap¬ 
pears to be secondary, and may have been derived from a 
vein, resembling those so frequently met with in Scotland 
traversing our primitive rocks. 
III. Specimens from Neill’s Cliffs And Cape Stewart 
in Jameson’s Land. 
1. Sandstone composed of quartz, felspar, flinty slate,' 
and silver-white mica. 
2. Same sandstone, with imbedded crystals of red felspar. 
3. Slaty sandstone. 
4. Sandstone impregnated with red iron-ore. 
5. Common grey sandstone. 
G. Common sandstone, stained yellow. 
7. Common sandstone, but of coarse grains. 
8. Sandstone with pebbles, the size of a bean, of common 
quartz. 
9. Coarse granular common grey sandstone. 
10. Common grey sandstone, shewing well its constitueiit 
parts, which are grey disintegrated felspar, grey 
quartz, and silver-white mica. This specimen con¬ 
tains intermixed portions of common black bitumi¬ 
nous slate-coal.
