But a far more important consideration, as I believe, is that, during the process of further modification, by which two varieties are supposed on my theory to be converted and perfected into two distinct species, the two which exist in larger numbers from inhabiting larger areas, will have a great advantage over the intermediate variety, which exists in smaller numbers in a narrow and intermediate zone. For forms existing in larger numbers will always have a better chance, within any given period, of presenting further favourable variations for natural selection to seize on, than will the rarer forms which exist in lesser numbers.
Geology would lead us to believe that almost every continent has been broken up into islands even during the later tertiary periods; and in such islands distinct species might have been separately formed without the possibility of intermediate varieties existing in the intermediate zones. By changes in the form of the land and of climate, marine areas now continuous must often have existed within recent times in a far less continuous and uniform condition than at present.
Thirdly, when two or more varieties have been formed in different portions of a strictly continuous area, intermediate varieties will, it is probable, at first have been formed in the intermediate zones, but they will generally have had a short duration.
"Well, we must try to get the balloon into a medium zone of the atmosphere, and there keep her suspended between the perils of the heavens and those of the earth.
"We have delayed too long," exclaimed the doctor; "we must now pass through a zone of fire, with our balloon filled as it is with inflammable gas!"
Carried along a few hundred feet above the ground she was better able to appreciate the Titanic proportions of the storm than when she had flown in the comparative serenity of the zone
above the clouds, for now she could distinctly see the effect of the wind upon the surface of Barsoom.
But the only zones
of the globe in which the moon passes the zenith, that is, the point directly over the head of the spectator, are of necessity comprised between the twenty-eighth parallels and the equator.
Had this tail any prehensile power, I should straightway bethink me of Darmonodes' elephant that so frequented the flower-market, and with low salutations presented nosegays to damsels, and then caressed their zones
. On more accounts than one, a pity it is that the whale does not possess this prehensile virtue in his tail; for I have heard of yet another elephant, that when wounded in the fight, curved round his trunk and extracted the dart.
That this power exists in any regions and for any classes is the result of Fog; which prevails during the greater part of the year in all parts save the torrid zones
. That which is with you in Spaceland an unmixed evil, blotting out the landscape, depressing the spirits, and enfeebling the health, is by us recognized as a blessing scarcely inferior to air itself, and as the Nurse of arts and Parent of sciences.
