90 Robert Chambers, Esq., on Changes of the 
became inclined rather to regard them as belonging to a dis- 
turbed than to a steady district. The objection from the 
terrace at a lower level in Kortsfiord may be allowed to give 
way, for there are so many anomalous markings in that val- 
ley, and in Komagfiord (to be presently adverted to), that a 
mistake may probably have happened. What adds in some 
degree to the probability of the Alten terraces being part of 
the district of disturbance, there are similar sandy forma- 
tions connected with other rivers at Melsvig and Talvig ; and 
these, being five or six miles less advanced upon the presumed 
line of movement, are proportionately lower. If we assume 
that the district of disturbance extends thus far, the vertical 
movement connected with that disturbance at Alten must be 
regarded as equal to the difference between 143 and 239, or 
96 feet. Does the movement extend farther southward ? 
We should have to answer in the negative if M. Bravais is 
right in saying that the great Alten terrace goes for four or 
five leagues along the valley without change of height ; but 
this point may be worthy of future inquiry. 
M. Bravais indicated the existence of a faint intermediate 
line, which he observed both at Hammerfest and Alten, and 
which he conceived to imply an intermediate movement. 
But the fact is, there are, at many stations throughout the 
disturbed district, terraces over and above, though mixed 
up with, the noted two which are here discussed. At Ham- 
merfest, besides the intermediate line alluded to by M. 
Bravais, which is formed by a grand terrace of blocks fallen 
from the schistous mountain behind the town, there is, on a 
hill-face near by, a series of shingle terraces, scantily covered 
with vegetation, and precisely resembling shingle beaches of 
the present day, at 87, 123, and 144 feet. There is also a 
ring terrace of transported matter, topped with water-laid 
sand, round the Lake of Hammerfest, at 97 feet above the 
sea. Here, it will be observed, are traces of the sea at not 
less than three elevations superior to the higher of the two 
lines. In Rypfiord and at Indre Sioholmen there are also 
terraces above the higher line. Such is likewise the case at 
Qualsund. In Komagfiord, at the entrance of its little river, 
there is a series of terraces both below and above the lower
