that Kaldhol's heights of the upper limit of submergence in this region 

 are often too high. 



Koklerup's observations in the Bergen district were also to a great 

 extent difficult to bring into harmony with our formula, but he has 

 obviously estimated his Tapes levels much too low as a rule. 



The Uniform Character of the Lateglacial and Postglacial Upheaval 

 along the West and North Coast of Fenno-Scandia. 



On the whole the results of the preceding" investigations demonstrate 

 that, in spite of the possible local differences in the gradient of upheaval 

 (mentioned p. 253), the lateglacial and postglacial upheaval of the land 

 has proceeded remarkably regularly and uniformly along the whole of 

 the western and northern coasts of P'enno-Scandia, from the region of 

 Christiania Fjord to the east and south coast of the Kola Peninsula. 



Its relative rate appears to have been so uniform along the w'hole 

 of this long coast, that, when its height be reduced by 5 metres, very 

 nearly the same proportion, or about 68.5 per cent, of the rest of the 

 upheaval has everywhere been accomplished during the period between 

 the time of the deepest lateglacial submergence and the transgression of 

 the Tapes-sea; and this relation seems to be the same in the outer coastal 

 regions where the upheaval has been relatively small, as farther inland 

 where it has been much greater. We are thus actually able to compute 

 approximately the probable level of the Tapes-sea at any place where we 

 know the upper limit of submergence, or z'ice versa where we know the 

 height of the Tapes-line we can compute the height of the upper limit 

 of submergence. 



An important result of our previous investigations was that, on the 

 whole, the levels of the strandfiat appear to stand at very similar heights 

 above the sea in all regions of the Norwegian coast where they have been 

 investigated. 



These facts constitute conclusive evidence that the earth's crust in 

 these regions has very nearly returned to the same horizontal position 

 which it had before the last glacial submergence, only that the shore-line 

 stood then perhaps betzveen to and ij metres higJier, in relation to the 

 land, than it does now. 



The uniform relation which we have found between the heights of 

 the observed upper limit of lateglacial submergence and those of the Tapes- 

 line confirms in a striking manner the correctness of these conclusions. 



May we assume that the upheaval of the land is now practically at 

 an end along the coast of Norway and that the earth's crust has very 

 nearly found its new position of equilibrium after the last glacial sub- 

 mergence?
