It has been suggested that the stripping off by denudation of dense masses from one part of a continent and the delivery of the same into the bed of the ocean must have a decided effect in causing changes of temperature in the earth's crust below, or, in other words, in causing the subterranean isothermals to shift their position.
Such facts teach us how many meteorological contrasts Europe presents, how many climates it contains. Necessarily it is full of modified men. If we examine the maps of monthly isothermals, we observe how strikingly those lines change, becoming convex to the north as summer approaches, and concave as winter.
Thus, in one region a species may possess peculiar medicinal qualities which it wants in another, or it may be hardier and better able to resist cold. The average range in altitude, says Hooker, of each species of flowering plant in the Himalayan Mountains, whether in the tropical, temperate, or Alpine region, is 4000 feet, which is equivalent to twelve degrees of isothermals of latitude.
And a like division of isothermals is made in the case of all our mountain systems, extending in both directions from the equator.
