The chemical and mineral world furnish us with many instances of the growth and development of forms closely resembling the forms of the vegetable world. What is known as "metallic vegetation," as shown in the "lead tree," gives us an interesting example of this phenomenon. The experiment is performed by placing in a wide-necked bottle a clear acidulated solution of acetate of lead. The bottle is corked, a piece of copper wire being fastened to the cork, from which wire is suspended a piece of zinc, the latter hanging as nearly as possible in the center of the lead solution. When the bottle is corked the copper wire immediately begins to surround itself with a growth of metallic lead resembling fine moss. From this moss spring branches and limbs, which in turn manifest a growth similar to foliage, until at last a miniature bush or tree is formed. Similar "metallic vegetation" may be produced by other metallic solutions. All of you have noticed how crystals of frost form on window panes in shapes of leaves, branches, foliage, flowers, blossoms, etc. Saltpeter when subjected to the effect of polarized light assumes forms closely resembling the forms of the orchid. Nature is full of these resemblances. A German scientist recently performed a remarkable experiment with certain metallic salts. He subjected the salts to the action of a galvanic current, when to his surprise the particles of the salts grouped themselves around the negative pole of the battery, and then grew into a shape closely resembling a miniature mushroom, with tiny stem and umbrella top. These metallic mushrooms at first presented a transparent appearance, but gradually developed color, the top of the umbrella being a bright red, with a faint rose shade on the under surface. The stems showed a pale straw color. This was most interesting, but the important fact of the experiment consists in the discovery that these mushrooms have fine veins or tubes running along the stems, through which the nourishment, or additional material for growth, is transported, so that the growth is actually from the inside, just as is the case with fungus life. To all intents and purposes, these inorganic metallic growths were low forms of vegetable his. But the search for Life does not end with the forms of the mineral world as we know them. Science has separated the material forms into smaller forms, and again still smaller. And if there is Life in the form composed of countless particles, then must there be Life in the particles themselves. For Life cannot come from non-Life, and if there be not Life in the particles, the theory of Omnipresent Life must fan. So we must look beyond the form and shape of the mineral--mist separate it into its constituent parts, and then examine the parts for indications of Life.
