THE STRANDFLAT AND ISOSTASY. 



26- 



Ramsay assumes these higher shore-lines to be of intergiacial age, 

 as they have a much older appearance than the lower ones. 



The heights of Ramsay's two lower shore-lines corresponding- to the 

 Norwegian shore-lines of the upper limit of submergence and the Tapes- 

 level, are given in the following table (in metres). (/) added to the 

 figures indicates measurements by levelling, (a) by aneroid-barometer. 

 The heights of the Tapes-line computed by our formula (2) are given in 

 the fourth column, and the difference between these values and the ol)- 

 served heights of the Tapes-line are given in the fifth column.

The observed and the computed values of the height of the Tapes-line 

 agree fairly well, but we find here a somewhat similar distribution of 

 the positive and negative differences. The observed heights of the Tapes- 

 line are relatively a little too high along the north coast of the land, from 

 Ril)achi l^cninsula to Kekora on the Murmanski Coast, while they are 

 slightly too low along the coast of the eastern and southern part of the 

 Kola Peninsula. The differences are no greater than might be expected 

 to be within the limits of observational error, but, nevertheless, there 

 seems to l)e a certain system in their geographical distribution. 



It was previously mentioned (p. 258) that according to Ramsay the 

 White Sea may probable have been transformed into a fresh-water lake
