The discoveries by Desprets have explained all this, but at the same time they have enlarged our views respecting the variety of wjys in which ice can act as a geological agent when an arctic current is present to assist in its formation. The differences between the condition of the Labrador and the Norwegian Fiords is remarkable; while the first named are closed by ice during at least six months of the year as a consequence of the Arctic Current flowing past them, the last named, according to Admiral Irminger, are kept open by a constant flow of warm water from the south-west, and the effect of this warm current is felt as far as Cape North. The cessation of the Labrador Arctic and Davis Strait Current by a general rise of the land between Greenland and Labrador would greatly Vide any good recent Map of the Arctic regions. change oce.inic circulation according to the views of Dr. Carpenter.
