In all products of the earth, which pertain, as was said above, either to the vegetable or to the animal kingdom, there is a kind of image of creation, and a kind of image of man, and also a kind of image of the infinite and the eternal; this was shown above (n. 313-318); also that the image of the infinite and the eternal is clearly manifest in the capacity of all these for infinite and eternal propagation. They all, therefore, receive means of propagation; the subjects of the animal kingdom through seed, in the egg or in the womb or by spawning; and the subjects of the vegetable kingdom through seeds in the ground. From which it can be seen that although the more imperfect and the noxious animals and plants originate through immediate influx out of hell, yet afterwards they are propagated mediately by seeds, eggs, or grafts; consequently, the one position does not annul the other.
