But the present actual state of knowledge on this subject forbids us any longer to accept theories for facts, premises for conclusions, or fallacious reasoning for legitimate induction. Truth and daylight never meet in a corner, and no one, in our day, need go to the bottom of a well in search of either. We are forever stumbling over the truth without knowing it, because our old traditional beliefs, like so many superannuated grasshoppers, are constantly springing up in our path and diverting our attention from her. There are physiological facts enough daily obtruding themselves upon our attention, if we would but notice them, in the case of wayside plants, garden and household weeds, and the more aggressive vegetation of worn out pasture-lands, to satisfy us of the truth of our theory, were it not for the swarms of these old traditional grasshoppers continually rising into the air before us, and shutting out the truth as it is in nature. And the worst feature about this whole business is, that we have come to regard these multitudinous insects as a delight instead of a burden. But it is hardly necessary to pursue this subject further. We have shown, or shall show in the succeeding pages, that all crystalline forms come from necessary or favoring statical conditions; that all infusorial forms come in the same way, only their conditions may be said to be dynamical rather than statical; that all mycological forms (fungi) are dependent, for their primary manifestation, on conditions of moisture and decay; that all plant-life, from the lowest cryptogam to the lordliest conifer, is dependent on some similar incidence of conditions; that the mastodon, now only known by his fossil remains, must have wallowed forth from his "necessary mire" (plasmic conditions) in the Eocene period; and that all animal life must have come from some underlying law of primordial conditions, as impressed upon matter, in harmony with the "Divine Intendment" from the beginning; and that this law is still operative in the production of new forms of life whenever and wherever the same may appear. We shall also show that all living organisms, such as seeds, fungus-spores, morphological cells, etc., perish at a temperature of about 100° C., and that _Bacteria, Torulæ_, and other infusorial forms, making their appearance in super-heated flasks, originate not from morphological cells, plastide particles, bioplasts, or any other vital organism, but from indestructible vital units, which are everywhere present in the organic matter of our globe, and ready to burgeon forth into life whenever the necessary vital conditions exist, and the proper incidences of environment occur.
