Now, when I saw those two plants growing in the Western Pyrenees, between France and Spain, and with them the beautiful blue butterwort, which grows in these Kerry bogs--we will go and find some--what could I say but that Spain and Ireland must have been joined once?
I suppose it must be so.
Again.

There is a little pink butterwort here in the bogs, which grows, too, in dear old Devonshire and Cornwall; and also in the south-west of Scotland.

Now, when I found that too, in the bogs near Biarritz, close to the Pyrenees, and knew that it stretched away along the Spanish coast, and into Portugal, what could my common sense lead me to say but that Scotland, and Ireland, and Cornwall, and Spain were all joined once?
Those are only a few examples.

I could give you a dozen more.

For instance, on an island away there to the west, and only in one spot, there grows a little sort of lily, which is found I believe in Brittany, and on the Spanish and Portuguese heaths, and even in North-west Africa.
And that Africa and Spain were joined not so very long ago at the Straits of Gibraltar there is no doubt at all.
But where did the Mediterranean Sea run out then?
Perhaps it did not run out at all; but was a salt-water lake, like the Caspian, or the Dead Sea.
