of the Arctic climate and Fauna. Then as climate changed, arctic fauna
would take place of ice, and an inundation of plants from different
temperate countries <would> seize the lowlands, leaving islands of arctic
forms. But if this had happened on an island, whence could the new forms
have come,--here the geologist calls in creationists. If island formed,
the geologist will suggest <that> many of the forms might have been
borne from nearest land, but if peculiar, he calls in creationist,--as
such island rises in height &c., he still more calls in creation. The
creationist tells one, on a <illegible> spot the American spirit of
creation makes _Orpheus_ and _Tyrannus_ and American doves, and in
accordance with past and extinct forms, but no persistent relation
between areas and distribution, Geologico-Geograph.-Distribution.

{126} In the _Origin_, Ed. i. p. 366, vi. p. 516, the author does
not give his views on the distribution of alpine plants as original
but refers to Edward Forbes' work (_Geolog. Survey Memoirs_, 1846).
In his autobiography, Darwin refers to this. "I was forestalled" he
says, "in only one important point, which my vanity has always made
me regret." (_Life and Letters_, i. p. 88.)

{127} <The following is written on the back of a page of the MS.>
Discuss one or more centres of creation: allude strongly to
facilities of dispersal and amount of geological change: allude to
mountain-summits afterwards to be referred to. The distribution
varies, as everyone knows, according to adaptation, explain going
from N. to S. how we come to fresh groups of species in the same
general region, but besides this we find difference, according to
greatness of barriers, in greater proportion than can be well
accounted for by adaptation. <On representive species see _Origin_,
Ed. i. p. 349, vi. p. 496.> This very striking when we think of
cattle of Pampas, plants <?> &c. &c. Then go into discussion; this
holds with 3 or 4 main divisions as well as the endless minor ones
in each of these 4 great ones: in these I chiefly refer to mammalia
&c. &c. The similarity of type, but not in species, in same
continent has been much less insisted on than the dissimilarity of
different great regions generically: it is more striking.
