These instances are sufficient for the purpose of illustrating the proposi- 
tion contained in this paper, but those who choose to verify it further will 
find abundant evidence of it in the published accounts of our flora. The 
New Zealand case, however, is not so striking as that of the Galipagos, as 
will appear from the following account given by Mr. Darwin. He tells us 
that in James Island thirty out of the thirty-eight endemic species are 
peculiar to it, as were twenty-two out of the twenty-six found in Albemarle 
Island, the same special feature also prevailing in Charles and Chatham 
Islands. He further illustrates this peculiarity in distribution by the case 
of Scalesia, an arborescent genus of the Composite, confined to the Archi- 
pelago, and containing six species, not one of which was found to grow on 
any two islands, and he adds, to use his own words « the distribution of the 
tenants of this Archipelago would not be nearly so wonderful, if, for instance, 
one island had a mocking-thrush, and a second island some other quite dis- 
tinct genus ; or if the different islands were inhabited, not by representative 
species of the same genera of plants, but by totally different genera, as does 
to a certain extent hold good; but it is the circumstance that several of the 
islands possess their own species of mocking-thrush, finches, and numerous 
plants, these species having the same general habits, occupying analogous 
situations, and obviously filling the same place in the natural economy of 
this Archipelago that fills me with wonder. I must repeat, that neither the 
nature of the soil, nor the height of land, nor the climate, nor the general 
character of the associated beings, and therefore their action one on another, 
can differ much in the different islands, and there seems to be no special
