CampbelL I^ '' ^ -^ TxtioodjLS I (confirmation of the general idea advanced in the hypothesis can be easily obtained by applying it to predict what will be found in certain places or under certain circum- stances. Many success- ful predictions of this kind have been made for the area comprised by New Zealand and its surrounding islands (the Kermadecs, 420 miles north; Chathams, 375 miles east; and Auck- lands, 190 miles south). It will be well to instance a few of these. To begin with simple cases (129); from the fact that to the east of these outlying islands the soundings are in general of enormous depth, while the water between them and New Zealand is comparativel}' shallow, one may infer that their floras have in general the same sources of origin as that of New Zealand. This is indicated also by the very few species in them, other than their own local endemic species, which do not occur in New Zealand. If they had received their flora by casual transport over sea, one would expect that it would be a miscel- laneous assortment, and that it would not show any numerical relations to the flora of the larger island. But as such relation- ships are shown very clearly one may, I think, take it for granted that the connection was by land, at least so far as the bulk of the flora of these islands is concerned. Now in this case it is clear that on the hypothesis ol' Age and Area, this flora should in general be very old in New Zealand, or it could not have "^JVTouj^Cuxrte- / New Zealand and outlying islands.
