88 Robert Chambers, Esq., on Changes of the 
Hammerfest to Beritsmol—that is, in a line south-south-east 
—is tolerably equable in proportion to the space passed over ; 
but when we turn off into Varg Sund, in a line south-south- 
west, the rise is much slower. To give particulars: Between 
Hammerfest and Beritsmol, a space of 114 geographical 
miles, the rise is 46 feet; but from Beritsmol to Saraby, 9} 
miles, it is only 24 feet; while from this to Komagfiord, 9 
miles more, it is 25 feet. If, however, we form a line nearly 
coincident with that of the first line of observation, as in the 
accompanying map, and, prolonging this into the mainland, 
raise upon it vertical lines touching the various positions in 
Varg Sund, we shall find that egual spaces are passed through 
in this portion of the affected district within equal spaces of the 
rise. It therefore appears that the rise is not slower in Varg 
Sund than in the sound between Qualée and Seiland, but only 
the terrace is there not so coincident with the line of rise. The 
rise observably becomes accelerated as we pass on to Komag- 
fiord, because the trend of the coast in that quarter gets 
more into a conformity with the line of rise. The heights 
taken on opposite coasts, moreover, as at Molstrand and 
Quisnaes, near Neeverfiord and at Rabastynaes, at Saraby 
and Olderfiord, correspond pretty well with this theory of the 
direction of the movement. In short, if a fair allowance be 
made for inaccuracy of maps, and the indeterminateness of 
the base line of the measurement (for a high water mark is 
in some places difficult to hit), it will appear that there is a 
remarkable approach to equability of rise throughout the 
whole of the space between Hammerfest and Komagfiord, 
the rate being pretty uniformly about 4 feet in a geographi- 
cal mile. 
M. Bravais regarded the possibility of the terraces having 
either risen at the one end or fallen at the other, so as to 
produce the slope; but he had not probably observed the two 
terraces which run along the coast to the southward, with 
little interruptions, for a space of about 180 miles, observing 
to all appearance, one uniform relation of heights, at 55 and 
143 feet. I consider the two sloping terraces of the northern 
sounds, as a disturbed portion of the system represented by 
the two southern terraces. If this be a just view, the dis-
