Professor Owen[12] says: "There are organisms (vibrieo, rotifer, macrobiotus, etc.) which we can devitalize and revitalize--devive and revive--many times. As the dried animalcule manifest no phenomena suggesting any idea contributing to form the complex one of 'life' in my mind, I regard it to be as completely lifeless as is the drowned man, whose breath and heat have gone, and whose blood has ceased to circulate. * * * The change of work consequent on drying or drowning forthwith begins to alter relations or compositions, and in time to a degree adverse to resumption of the vital form of force, a longer period being needed for this effect in the rotifer, a shorter one in the man, still shorter it may be in the amoeba." "There is," says Dumas,[13] "an eternal round in which death is quickened and life appears, but in which matter merely changes its place and form." Let us now compare the inorganic world with the organic--the inanimate with the animate--and see if there does exist an inseparable boundary between them. The fundamental properties of every natural body are matter, form, and force. One important point to be noticed is, that the elements which compose all animate bodies are the very elements that help to build up the inanimate bodies. No new elements appear in the vegetable or animal world which are not to be found in the inorganic world. The difference between animate and inanimate bodies, therefore, is certainly not in the elements which form them, but in the molecular combination of them; and it is to be hoped that molecular physics will, at some not far distant time, enlighten us as to the peculiar state of aggregation in which the molecules exist in living matter. As to the form, it is impossible to find any essential difference in the external form and inner structure between inorganic and organic bodies--for the simple monad, which is as much a living organism as the most complex being, is nothing but a homogeneous, structureless mass of protoplasm. But just as the inorganic substance, according to well-defined laws, elaborates its structure into a crystal of great beauty, so does the protoplasm elaborate itself into the most beautiful of all structures--the cell unit.
