A relanlation of tlie uplieaxal of the land caused in the manner 

 described above, may influence the relation between the heights to which 

 tlTC land was raised during the periods before and after the Tapes- 

 Litlorina period. We may, tlicrefore, be prepared to find that our 

 formula, based on tlie uplieaval of tlie north-western coast of Fenno- 

 Scandia, will not hold good in its central and eastern regions. 



d'lie retardation of the uplieaval caused by the weight of the trans- 

 gressing sea, nia\- l)c ex])ected to have been most considerable, compara- 

 tively, during the earlier periods of the upheaval, when the transgressing 

 sea was deepest. Hence we may expect that in the regions where this 

 sea was especially deep, the height of upheaval between the upper limit 

 of submergence and the Tapes-line was lower in relation to the upheaval 

 after the Tapes period, than it was in other regions. This seems to be 

 borne out by the obser\"ations. In southern Sweden the observed heights 

 of the Tapcs-Littorina level depart, on the whole, less from the values, 

 computed by our formula from the heights of "the upper marine limit", 

 than they do further north in Sweden. 



A. G. Högbom has attempted a comparison at the following localities:

This is already sufficient to show that the departures of the ob- 

 served values from the computed ones of the heights of the Tapes- 

 Littorina level are in these regions of quite a different order than those 

 we have found along the wdiole of the north and west coast of Fenno- 

 Scandia. 



It may especially seem striking to find such a great departure of 

 -I-15.7 at ]Mariestad, Lake\>ner, while in the region of Christiania Fjord, 

 about 200 kilometres to the north-west, the departures were between
