of these peaks, but I take it that, as on the northwestern coast, 

 these are more resistant granite areas, which are presumably of 

 later origin than the surrounding gneiss. 



The east coast profile, if we do not take into consideration the 

 isolated alpine area at Angmagssalik, thus shows that the gneiss 

 surface from the southernmost point drops toward the level of the

sea until 70° N. lat., where it rises abruptly to an elevation of 2,000 

 meters, and then again drops toward the north until at 82° N. lat. 

 it disappears beneath the sea. 



The astonishing similarity between the two profiles strikes one 

 at once. Both slope from 60° N. lat. toward 70° N. lat., with a 

 drop of about 2,000 meters; then the country rises abruptly again 

 to 2,000 meters, only to drop again to sea-level at about 80° N. lat.
