seeds or animals transported to an island, even if far less well-stocked than Britain,
more than one would be so well fitted to its new home, as to become naturalised. But

| The identity of many plants and animals, on mountain-summits, separated from each other by hundreds of miles of lowlands, where
Alpine species could not possibly exist, is one of the most striking cases known of the same species living at distant points, without the apparent possibility of their having migrated from one
the other. It is indeed a remarkable fact to see so many
the same
living on the snowy regions of the Alps or Pyrenees, and in the extreme northern parts of Europe; but it is far more remarkable, that the plants on the White Mountains, in the United States of America, are all the same with those of Labrador, and nearly all the same, as we hear from Asa Gray, with those on the loftiest mountains of Europe. Even as long ago as 1747, such facts led Gmelin to conclude that the same species must have been independently created at
distinct points; and we might have remained
