QUOTE : It must not be supposed that atoms of every sort can be linked in every variety of combination. If that were so, you would see monsters coming into being everywhere. Hybrid growths of man and beast would arise. Lofty branches would spread here and there from a living body. Limbs of land-beast and sea-beast would often be conjoined. Chimeras breathing flame from hideous jaws would be reared by nature throughout the all-generating earth.
