appeared to be a pale-red, massive, granite-like rock, in the northwestern part of Cape 
Meredith ((?.,), near to the Three Crowns, the older formation consists of a distinctly 
banded series dipping about NVV. Most of this stratified series is dark-coloured 
with subordinate layers which are lighter in colour. At d these beds are traversed 
by a 23ink-coloured dike. 
On a later occasion I got a chance to visit Cape Meredith from the land side. 
At the cliff was found inaccessible, so that as to this part of the older formation 
I must confine my.self to venturing the supposition that it may be a series of 
crystalline schi.sts traversed by a granitic or pegmatite dike. 
In the bay between the two points of 
Cape Meredith the descent to the sea is 
easy, and here I reached the j^art of the 
older formation. The sandstone is reddish 
and arkose-like; also in the undermost part 
its bedding is nearly horizontal, though the 
surface of its basement is very rugged with 
hollows and small hillocks. This basement 
here consists of gneiss which is invaded by 
a plentiful intrusion of granite, in some 
spots the latter rock forming the jiredom- 
inant constituent and including angular frag- 
ments of gneiss. These crystalline rocks are 
strongly decayed, easily crumbling, at least 
to a depth of five meters underneath the 
contact with the sandstone. Farther from 
the contact the rock was fresh, unaltered, 
pale red in colour. Here were noticed some 
narrow veins of coarser rock, exhibiting a 
very beautiful granophyric structure. 
The altitude of the contact between the two formations is very unequal in dif- 
ferent parts of the section. Near the southmost point of the cajae the older rock 
(gneiss or granite) rises to 74 m., but — as seen from fig. 8 — on both sides this 
older formation soon disappears below the sea-surface. 
Unfortunately my specimens from Cajae Meredith were kept on board the Aiit- 
arctic and were lost with it. Thus I am not able to give any details about the 
lithological characters of the crystalline rocks. The age of the formation here form- 
ing the basement of the sandstone cannot be definitely settled, but the whole, 
the gneiss and granite as well as the siq3posed crystalline schists, reminds me 
forcibly of Archæan rocks.
