happens in the arctic regions. Yet it cannot be said that small islands will not support
→small
mammals, for they occur in many parts of the world on very small islands,
close to a continent; and hardly an island can be named on which our smaller quadrupeds have not become naturalised and greatly multiplied. It cannot be said, on the ordinary view of creation, that there has not been time for the creation of mammals; many volcanic islands are sufficiently ancient, as shown by the stupendous degradation which they have
and by their tertiary strata: there has also been time for the production of endemic species belonging to other classes; and on continents it is
that
→mammals
appear and disappear at a quicker rate than other and lower animals.
terrestrial mammals do not occur on oceanic islands,
mammals do occur on almost every island. New Zealand possesses two bats found nowhere else in the world: Norfolk Island, the Viti Archipelago, the Bonin Islands, the Caroline and Marianne Archipelagoes, and Mauritius, all possess their peculiar bats. Why, it may be asked, has the supposed creative force produced bats and no other mammals on remote islands? On my view this question can easily be answered; for no terrestrial mammal can be transported across a wide space of sea, but bats can fly across. Bats have been seen wandering by day far over the Atlantic Ocean; and two North American species either regularly or occasionally visit Bermuda, at the distance of 600 miles from the mainland. I hear from Mr. Tomes, who has specially studied this family, that many

species have enormous ranges, and are found on continents and on far distant islands. Hence we have only to suppose that such wandering species have been
