A corresponding change in climate would accompany this 
diversity in the conformation of the land and water ; and 
although the average heat of this quarter of the globe might 
not be much different from what is now the case, yet the change 
would have a tendency to promote the increase of permanent 
snow and ice in northern latitudes. In short, it would ap- 
proximate to that now in existence in the southern hemi- 
sphere. Icebergs detached from the mountainous regions 
would float upon the sea, depositing their spoils as they 
gradually melted ; while some being drifted up the narrow 
inlets, would convey the fragments into situations where their 
presence cannot otherwise be accounted for. That the 
boulders in question were transported by this means, I have 
no doubt, but further investigation is necessary satisfactorily 
to establish the point ; and I hope at some future time to be 
enabled to adduce much additional evidence in support of 
this view.
