﻿714 SUMMARY OF THE CONTENTS. 



On pp. 627 — 637, an attempt is made to prove that a sub- 

 mergence corresponding to the sinking of land in the Baltic area 

 during the httorina-time has probably not occurred in the Kri- 

 stiania region. 



On pp. 638 — 645, it is emphatically stated, that a submer- 

 gence corresponding to the sinking of land during the ancylus- 

 time in the Baltic area is also at present considered very 

 doubtful in the Kristiania region ; the superposition af portlandia 

 clay (at Grorud, Solberg, etc, in Aker) on mytilus-åeiposits, 

 may perhaps be explained by clay-slips, analogous to the land- 

 slip at Værdal in 1893. 



On pp. 645 — 650, the question of climatic changes after the 

 epiglacial time is discussed. No evidences of oscillations during 

 postglacial time have hitherto been derived from the moUusc 

 fauna. 



The change of climate seems to have been continuous 

 during the w^hole time from the deposition of the upper ostræa- 

 banks to the lowest tapes-banks, with continuously increasing 

 temperature almost up to the end of the uplift, and afterwards 

 with decreasing temperature during recent times. 



The table on p. 651 gives in a short summary a review of 

 the changes of level and climate from the ra-time up to recent 

 times. The first column shows the different morainic stages etc, 

 corresponding to the subsequent clay-deposits enumerated in 

 the second column; in the third column are enumerated the 

 corresponding littoral deposits (a. in Smålenene, b. at Kristiania). 

 Column four indicates the relative composition of the moUusc 

 fauna in the different deposits. Column five enumerates coasts 

 of corresponding climates in recent times; column six gives the 

 temperatures assumed to correspond with the different sub- 

 sequent faunas. Column seven gives the percentages of sub- 

 mergence (sænkning) and uplift (stigning).
