The fact of varieties of one species, when they range into the

very

the

our

view that species →of all kinds are only well-marked and permanent varieties. Thus the species of shells which are confined to tropical and shallow seas are generally brighter-coloured than those confined to cold and deeper seas. The birds which are confined to continents are, according to Mr. Gould, brighter-coloured than those of islands. The insect-species confined to sea-coasts, as every collector knows, are often brassy or lurid. Plants which live exclusively on the sea-side are very apt to have fleshy leaves. He who believes in the creation of each species, will have to say that this

for instance, was created →with bright colours for a warm

but that this other

became →bright-coloured by variation when it ranged into warmer or shallower waters.

When a variation is of the

being, we cannot tell how much

but who can tell how much of this difference may be due to the warmest-clad individuals having been favoured and preserved during many generations, and how much to the

action of the severe climate? for it would appear that climate has some direct action on the hair of our domestic quadrupeds.
