Nature, like a careful gardener, thus takes her seeds from a bed of a particular nature, and drops them in another equally well fitted for them.

The species of all kinds which inhabit oceanic islands are few in number compared with those on equal continental areas: Alph. de Candolle admits this for plants, and Wollaston for insects. →OMIT New Zealand, →for instance, with its lofty mountains and diversified stations, extending over 780 miles of latitude, →together with the outlying islands of Auckland, Campbell, and Chatham, contain altogether only 960 kinds of flowering
