GREENLAND :—INSULAR STRUCTURE. 329 
ative map from Sir Charles Giesecke’s chart, is 
such, that there seems to he the greatest probabi¬ 
lity, that it continues through the country to a 
conjunction with Scoresby’s Sound ; and, perhaps, 
also, with some of the more northern inlets. The 
distance across, beyond the observed extent of 
these inlets, is about 380 miles, as measured up¬ 
on the map. But this is not the only place where 
the western coast is broken by inlets. On the 
contrary, Sir Charles Gieseclce found, that, to the 
northward of Disco Island, as high as latitude 
76-1?°, the coast is not continuous, as at a distance 
it seems to be, but consists entirely of a range 
of islands. 
These facts, however, though they render the 
assumed opinion respecting the structure of Green¬ 
land extremely probable, must be acknowledged 
to leave it still in a conjectural condition. The 
statement of another circumstance, however, rela¬ 
ting to the current, will carry the opinion, I should 
think, almost beyond a doubt. Wherever a cur¬ 
rent is observed to set regularly into a sound or 
other inlet, carrying floating bodies along with it, 
and not returning them back again, it is evident 
such inlet must have another, or interior commu¬ 
nication with the sea; otherwise, the perpetual 
inset of a body of water would produce such an 
accumulation within, as not only to prevent any
