He remarked, however, that the intermediate terrace con- 
siderably alters the relative amount of the earlier and later 
elevations along the coast, reducing the first or most ancient 
to about 24 feet, making the second or intermediate move- 
ment of 22 feet, and leaving the third or most recent of 46 
feet, and therefore considerably greater than the other two. 
In a work published by me on Ancient Sea-Margins, 1 ex- 
pressed some doubts as to the alleged inclination of the Fin- 
mark terraces, being partly led thereto by the discovery, in 
other parts of the earth, of uniform levels for such markings ; 
while it likewise appeared to me that, for perfect proof of 
M. Bravais’s positions, we should have required either evi- 
dence of greater continuity in the appearances, or measure- 
ments taken at a greater number of points. I deemed it 
not unlikely that the fragments of terrace which he saw at 
different places might be, not representative of two great 
lines, as he supposed, but representative of a number of lines 
nearly if not quite equal to the number of the points of ob- 
servation. I was therefore glad when I was able to pay a 
visit to Finmark, with a view to making a rigid personal ex- 
amination of the terraces, and with the means of measuring 
their elevations more accurately than had yet been done. 
The result I am now to bring before this Society. 
The general fact of the existence of two continuous lines 
of erosion on the rocky coast between Kortsfiord and Ham- 
merfest I found to be true. They appear as part of the same 
system of terraces with those seen farther south, or as a 
prolongation of them; but, unlike those terraces, they do 
not observe a level, for the upper line is at one end not much 
less than a hundred feet higher than it is at the other. It 
is about the middle that they bear the best resemblance to 
the couple of terraces in Trom Sund and elsewhere. The 
resemblance is chiefly in likeness of elevation. As to the 
material, there is a difference throughout a great part of the
