Then, as Dana first pointed out with reference to the fjords as 
submerged river- valleys, the land had probabh- in the beginning 
of glacial time a much greater elevation than at prc^sent. Thus 
dt is quite possil)le, that during the great glaciation a considera- 
•'ble subsidence from the highest elevation occurred, followed dur- 
'ing interglacial time l)y a partial re-elevation of the land ; while 
"the earl}' marine deposits during the late glacial subsidence might 
'have been a second time so dei^ply depressed below the sea-level 
that generally they have not since been uplifted suftlcienth' to 
'appear above it. .\ccording to this explanation, it is easy to 
'conceiveAvhy the interglacial marine deposits are accessible Justin 
'the tracts which were least affected by the late glacial subsidence. 
1 take this opportunity to remai'k that in m}' opinion the marine 
sediments which .Murchison. Verueuil. and Keyserling* found at 
'Dwiiiaand Petsch«)ra in iKtithern Ikussia. and which liave been 
'lately traced over laige aicas Ity Tscliernyschew.t are |)i'oV)ably of 
'interglacial age. though they are not covered by till, as occurring 
at the outside ()f the last glaciation. But as theii- fauna con- 
tains such l)oreal and southei"n species as Cfiprimi ishiinliin and 
Cardiiim t'l/iifc, it is- no: probable tiiat they could be contempo- 
rary with the arc-tic fauna of the late glacial sulisidence in Scandi- 
navia. On the other liaiid. it is dillicull to believe that the con- 
sid(!rable oscillation of land in northern Russia could have taken 
•place so lately as in |jostglacial time. Hence there is some I'ea- 
'sonto infei' that the deposits in (|ueslion tielong to the iiitergla- 
'cial period, and it is my opinion that, like the undoubtedly inter- 
glacial deposits before-mentioned, they are still accessible al)ove 
the sea-level only outside of the region which was atfectcd l>y 
'the late glacial submergence.
