Swiss Alps, several deep depressions, formerly the beds of immense glaciers, have become a sort of continental fjord, such as the lakes of Mag-
giore, Iseo, Lugano, Como, and Garda.* These lacustrine basins are
dosed at the south by large moraines, like the sea-gates of Norway, and
their waters, like those of the fjords, are gradually displaced by the alluvium brought down by Alpine torrents.

Norway, and it was still earlier that the indentations of the coast-lines
of Ireland and Brittany ceased to serve as beds to the solidified snows
of the surrounding mountains. As to the shores of the British Islands

sooner melted, because of the want of the necessary moisture. This is
the reason of the striking contrast presented in the British Isles and Ice-
