and the more nearly any two forms are related in blood, the nearer they will generally stand to each other in time and space; 1859 1860 1861

and 1866 1869

looking to distant provinces throughout the world, we find that →species in certain classes differ

little,

→from each other, whilst those in another class, or

a different →section of the same order, differ →greatly from each other. In both time and space the

lower

members of each class generally change less than the

higher;

but there are in both cases marked exceptions to the rule. →According to our

theory

these several relations throughout time and space are intelligible; for whether we look to the

forms

of life which have changed during successive

ages

→OMIT or to those which have changed after having migrated into distant quarters, in both cases

the
