nearly as terrestrial as the quail or partridge. In such cases, and many others could be given, habits have changed without a corresponding change of structure. The webbed feet of the upland goose may be said to have become
rudimentary rudimentary 1859 1860 1861 1866 1869 | almost rudimentary 1872 |
in function, though not in structure. In the frigate-bird, the

He who believes in separate and innumerable acts of creation
will will 1859 1860 1861 1866 | may 1869 1872 |
say, that in these cases it has pleased the Creator to cause a being of one type to take the place of one
of of 1859 1860 1861 1866 | belonging to 1869 1872 |
another type; but this seems to me only
restating restating 1859 1861 1866 1869 | re- stating 1860 | re-stating 1872 |
the fact in dignified language. He who believes in the struggle for existence and in the principle of natural selection, will acknowledge that every organic being is constantly endeavouring to increase in numbers; and that if any one
being vary being vary 1859 1860 1861 | varies 1866 1869 | being varies 1872 |
ever so little, either in habits or structure, and thus
