in the proportion between the extent and other circumstances 
of the two areas, and that by allowing due weight to all the 
evidences adduced in support of the view that Greenland was 
the source of the glacial phenomena of the area in question,

matical problem. 
Addendum. 
What strengthens and cogently proves the truth of my pre- 
vious statements is the circumstance that Professor NOkDENSKIOLD 
during his expeditious to the Yenisei, from the mouth of that river 
to Yeniseisk, found no evidence showing that any grand covering 
of ice existed in the Arctic lowlands of Siberia during the Glacial 
period. The fact that the glaciers of the Altai did not reach as 
far as to Yeniseisk may be explained by the dry climate of the 
highlands of Asia. —
