﻿SUMMARY OF THE GONTENTS. 683 



the sea-bottom, during the time of the greatest ice-sheet of 

 Europe, must have been uplifted at least 2600 metres higher 

 than it is at present. In a discussion of this hypothesis, Dr. 

 Frithjof Nansen (pp. 94 — 96) concludes that the explanation of 

 the occurrence of arctic shallow-water fossils in the great depths 

 of the Norwegian Sea by the theory of transportation by float- 

 ing ice or icehergs from the Polar Sea in recent time, is 

 extremely improbable. If so, no other explanation is left than 

 the supposition of a former uplift of the sea-bottom. 



Pp. 100 — 111. A Discussion of the Level of the Kristiania 

 Region during the Last Ice-Sheet. This chapter first discusses 

 the littoral shellbanks of the continental platform along the Nor- 

 wegian west coast at the depths of 100 — 200 metres: on Stor- 

 eggen {G. 0. Sårs, p. 101) outside the mouth of the Sognefjord 

 {James Grieg, p. 101), at Tromsø [Sparre- Schneider, p. 102). 

 They are compared with corresponding littoral shellbanks on the 

 continental platform to the south-west of Ireland [Godwin 

 Austen 1849) at Rockall (the Rockall Expedition 1896—1897; 

 pp. 105, 106) and off the Færæ Islands (the Danish Ingolf 

 Expedition, 1898, A. S. Jensen; pp. 106, 107). An attempt is 

 made to prove that all these littoral shell-banks at depths of 

 from 100 to 300 m. are to be referred to the last interglacial 

 time, probably to the latest part of it; the continental platform 

 must at this time have been uplifted about 100 — 300 metres 

 higher than it is at present. 



It is assumed, that this uplift has continued during the last 

 covering of Norway with a great ice-sheet. At the beginning 

 of the melting of the ice the land has probably been situated 

 much higher than it is at present; even sometime before the 

 ra-station of the ice-front, the land was uplifted at least 50 

 metres higher than it is at present in the Kristiania region ; 

 and during the continual melting of the ra-time, the land sank 

 still m.ore, to about 75 — 100 m. lower than it is at present, 

 during the last part of the deposition of the yoldia clay (the 

 younger yoldia clay).
